Description

Intravenous Bag Field of invention
The present invention relates to a medical fluid system. The present invention more particularly relates to an intravenous (IV) bag for providing IV fluid to patients.
Prior art
IV treatment is widely used for infusion of liquid substances directly into veins. IV treatment is applied for several purposes including delivery of preparations and medications, correction of electrolyte imbalances and dehydration treatment.
From WO 98/16183 Al, EP 0 145 825 Al, WO 2012/076690 Al, WO 83/01569 Al, US 4,465,488 A, WO 99/27885 Al, WO 2005/074861 Al, US 4,997,083 A, EP 0 442 406 Al and EP 0 974 331 A2, respectively, IV bags for intravenous administration of fluids to a patient are known. The IV bags comprises at least a first chamber and a second chamber separated by a wall-like structure. The IV bags have an outlet opening at the emptying end. Furthermore, the IV bags have an element, by which a fluid connection between the chambers can be establish. The element may e.g. be a valve, a breakable bung, or a heat-sealed weld. However, such element may be difficult to operate and may even be prone to malfunction, resulting in failure in establishing the adequate connection between the chambers.
When present IV bags are applied, the healthcare practitioners carrying out IV treatment as well as the patients receiving the treatment are exposed to aerosols containing medicine (in small doses) in the respirated air during the IV treatment. The contamination takes place when the preparation (medicine) is coupled to the patient. The tubing contains the preparation which has access to the air when the container cap is unscrewed. Before the tubing is connected to the patient's venous catheter, contamination takes place. When the spike from the tubing is removed from an empty preparation receptacle (e.g . a medicine bottle) and inserted into a saline (saline solution) bag the healthcare practitioners carrying out the IV treatment will be exposed to aerosols.
Further, today, it is not possible to empty the preparation receptacle completely since residual preparation (e.g . medicine) will be present in the tubing and the spike applied to carry out the IV treatment. Accordingly, doses of approximately 5-20 ml will not be used . This is a rather large percentage since the total dose is typically 100- 120 ml . As residual preparation (e.g . medicine) is present, the waste is categorised as toxic waste which poses substantial or potential threats to public health or the environment. When using the present IV bags, it can be difficult for the healthcare practitioners carrying out IV treatment to positively determine if a patient has received one or two treatments (e.g . medicine doses) or only saline whenever the healthcare practitioners forgets to sign for administrating the treatment in either the corresponding computer 5 system or at the patient's liquid chart. Accordingly, there is risk for inappropriate medication that can cause the patients to get worse.
Today, the treatment (e.g . medicine) and the saline are kept in separate containers. If the healthcare practitioners forget the saline for rinsing, it is time-consuming to go back to get it when the treatment (e.g . medicine) has been given . Thus, there is a need for an improved IV bag that reduces or even eliminates the above-mentioned disadvantages of the prior art.
It is an object of the invention to provide an IV bag that increases the safety of the healthcare practitioners carrying out IV treatment and reduces the frequency of allergies and eczema among healthcare practitioners carrying out IV treatment.
It is a further object of the invention to provide an IV bag that does not need to be disposed of as toxic waste.
Summary of the invention
The object of the present invention can be achieved by an IV bag as defined in the claims, Preferred embodiments are defined in the dependent sub claims, explained in the following description and illustrated in the accompanying drawings,

The IV bag comprises an activation member configured to establish fluid connection between the first compartment and the second compartment, wherein the activation member is a button configured to establish fluid connection between the first compartment and the second compartment when being activated.
Hereby, it is possible to deliver ail the preparation (medicine) to the patient so that no residual preparation will be present in the IV bag after use. Therefore, it is not necessary to dispose of the IV bag as toxic waste.
The invention makes it possible to provide an IV bag that increases the safety of the healthcare practitioners carrying out IV treatment and reduces the frequency of allergies and eczema among healthcare practitioners carrying out IV treatment.
The IV bag according to the invention is an IV bag for providing IV fluid to a patient. The IV bag may be applied to carry out ail types of IV treatment.

The activation member may be any suitable member capable of establishing fluid connection between the first compartment and the second compartment upon being activated either manually or electrically by using any suitable electrical activation means including automatic electric activation means. Hereby, it is possible to establish the desired fluid communication between the adjacent compartments by simple, reliable, user-friendly means. it may be beneficial that the IV bag comprises an inlet port for injection of a fluid into the IV bag. Hereby, a preparation (e.g. medicine) may be injected into the IV bag through the inlet port.
The inlet port may comprise a sealing member provided at the distal end of the inlet port. The inlet port may comprise a non-return valve for preventing back flow.
The inlet port may be provided together with an activation unit that may be arranged at an outer wall of the IV bag. It may be advantageous that the inlet port is connected to the first compartment. Hereby, it is achieved that a preparation (e.g. medicine) can be introduced into the first compartment which may contain a fluid such as saline. The IV bag can be connected to a patient's venous catheter for carrying out an IV treatment comprising the preparation introduced into the first compartment. When the patient has received the preparation introduced into the first compartment, the fluid in the second compartment (preferably a rinsing or flushing fluid) is led into the first compartment by activating the activation member. Accordingly, all medicine will be flushed out and dispensed through the outlet port of the IV bag. Therefore, the IV bag and the tubing connected to the outlet port of the IV bag will be "cleaned" by the rinsing or flushing fluid, and the contamination risk will be reduced significantly. Moreover, the IV bag can be disposed of as ordinary waste (not toxic waste).
It may be an advantage that the IV bag comprises an activation unit comprising an activation member and an inlet port.
Hereby, the healthcare practitioners carrying out IV treatment can easier carry out the IV treatment as both the activation member and the inlet port are provided close to each other at the activation unit.

Referring now in detail to the drawings for the purpose of illustrating preferred embodiments of the present invention, different embodiments of an IV bag 2 of the present invention are illustrated in Fig. 1.
Fig. 1 A illustrates a schematic view of a first embodiment of an IV bag 2 according to the invention. Fig. 1 B illustrates a schematic view of a second embodiment of an IV bag 2 according to the invention, and Fig. 1 C illustrates a schematic view of a third embodiment of an IV bag 2 according to the invention,
The IV bags 2 comprise a plurality of compartments 4, 4', 6, 6' defined by an upper portion 26 and lower wall(s) 28, 28' connected by a first outer wall 22 and a second outer wail 24, respectively. A hole 14 for suspending the IV bag 2 is provided in the upper portion 26,
Referring now to Fig, 1 A, it can be seen that the IV bag 2 comprises a first compartment 6 for a rinsing fluid and a second compartment 4 for a crystalloid fluid which may be saline. The first compartment 6 is arranged above the second compartment 4, A wall member 20 separates the first compartment 6 and the second compartment 4, The major portion of the wall member 20 separating the first compartment 6 and the second compartment 4 is sloped (with an angle a relative to horizontal H, when the IV bag 2 is in an upright position like illustrated in Fig. 1 A).
The IV bag 2 comprises an activation unit 16 comprising an inlet port 10 for introducing a preparation (e.g. medicine) into the first compartment 6. The activation unit 16 also comprises an activation member 8 shaped as a button that upon being activated (e.g. by pushing or turning the activation button 8) creates an opening and thus a fluid connection between the first compartment 6 and the second compartment 4 so that the crystalloid fluid (such as saline) will flow into the first compartment 6 due to gravity (since the wall member 20 separating the first compartment 4 and the second compartment 6 is angled relative to horizontal H). The activation member 8 may be configured to establish fluid connection between the first compartment 6 and the second compartment 4 upon being displaced, pulled or pushed in one or several directions e.g. sideways. The activation member 8 may be any suitable member capable of establishing fluid connection between the first compartment 6 and the second compartment 4 upon being activated either manually or electrically by using any suitable electrical activation means including automatic electric activation means.
Hereby, it is possible to clean the first compartment 6 when the preparation (e.g. medicine) introduced into the first compartment 6 is delivered to a patient through the outlet port 12 arranged in the bottom portion of the IV bag 2. Since the lower walls 28, 28' are angled (with angles β, β') relative to horizontal H, the preparation (e.g. medicine) introduced into the first compartment 6 can easily be delivered to a patient through the outlet port 12,
When the preparation (e.g. medicine) introduced into the first compartment 6 has been delivered to a patient through the outlet port 12, the activation button 8 is activated in order to create an opening and thus fluid connection between the second compartment 4 and the first compartment 6. Hereby, the crystalloid fluid (such as saline) is used to rinse the first compartment. Therefore, the IV bag 2 contains no residual preparation (e.g. medicine) after use. Accordingly, the IV bag can be disposed of as ordinary waste (since no residual preparation is left, the bag is not considered toxic waste).
In one embodiment, the first compartment 6 of the IV bag 2 may be pre- filled with a preparation (e.g. medicine). When using this IV bag, the safety of the patients receiving IV treatment and the healthcare practitioners carrying out IV treatment can be increased. Thus, neither the patients nor the healthcare practitioners carrying out IV treatment will be exposed to aerosols-containing medicine. Hereby, allergies and eczema among healthcare practitioners carrying out IV treatment may be prevented, The activation unit 16 extends along a section of the outer wail 22 and along a section of the separating wall member 20. Any suitable valve mechanism may be applied, including both mechanical and electronic valve mechanisms.
The IV bag 2 illustrated in Fig. 1 B comprises four compartments 4, 4', 6, 6'. The IV bag 2 comprises a first activation unit 16 provided along the outer wall 22 and extending along a portion of the first wall member 20, The activation unit 16 is equipped with an activation button 8 configured to establish a fluid connection between the fourth compartment 4' containing a fourth fluid (preferably a rinsing fluid or a crystalloid fluid such as saline) and the third compartment 6' that contains a third fluid (preferably a preparation or saline for being mixed with a preparation) and/or is configured to receive a fluid (e.g. a preparation) through an inlet port that may be provided in the activation unit 16. Due to the inclination of the wall member 20 (the angle between the wall member 20 and horizontal H is a), the fluid in the fourth compartment 4' can flow into the third compartment 6' by means of gravity (when the IV bag 2 is arranged vertically).
The IV bag 2 comprises a second activation unit 16' provided along the outer wall 22 and extending along a portion of the second wall member 20'. The activation unit 16' is provided with an activation button 8' configured to establish a fluid connection between the second compartment 4 and the first compartment 6. Since the second wall member 20' is angled (the angle between the second wail member 20' and horizontal H is α'), the fluid in the second compartment 4 can flow into the first compartment 4 by means of gravity provided that the IV bag 2 is arranged vertically as intended.
The IV bag 2 comprises a third activation unit 16" provided along the outer wall 22 and extending along a portion of the third wall member 20". The activation unit 16" has an activation member 8" adapted for establishing fluid connection between the second compartment 4 and the first compartment 6 that contains a first fluid (e.g. a preparation or a saline for being mixed with a preparation) and/or is configured to receive a fluid (e.g. a preparation) through an inlet port that may be provided in the activation unit 16". Due to the fact that the third wall member 20" is angled (the angle between the third wall member 20" and horizontal H is a"), the fluid in the second compartment 4 can flow into the firth compartment 6 due to gravity when the IV bag 2 is arranged vertically as intended. The IV bag 2 comprises an outlet port 12 arranged in the lowest corner section of the IV bag 2. Since the lower wall 28 is angled (the angle between the lower wail 28 and horizontal H is α'"), the fluid in the first compartment 6' can flow out through the outlet port 12 into a tubing (not shown) connected to a patient's venous catheter. In one embodiment according to the invention, the first compartment 6 and the third compartment 6' may contain saline and be configured to receive medicine through an inlet port provided in the activation unit 16, 16"'. Rinsing fluid may be provided in the second compartment 4 and in the fourth compartment 4'. Hereby, medicine may be introduced into the saline in order to achieve the correct medicine concentration.
Generally, it may be an advantage to have a compartment rinsing or flushing fluid in the compartments that are provided above and adjacent to each compartment provided with medicine or with an inlet for introducing medicine or another treatment. Hereby, the rinsing or flushing fluid can be used to rinse the medicine containing compartment. Fig. 1 C illustrates another embodiment of an IV bag 2 according to the invention. The IV bag 2 comprises an outlet port 12 arranged in the lowest corner section of the IV bag 2. As the lower wall 28 is angled (the angle between the lower wall 28 and horizontal H is α'), the fluid in the first compartment 6 can flow out through the outlet port 12. Similarly, the wail member 20 is angled (the angle between the wall member 20 and horizontal H is a) allowing for the fluid in the first compartment 6 to flow out through the outlet port 12.
The IV bag 2 comprises an activation unit 16 provided along the lower wail 28 and extending along a portion of the wall member 20. The activation unit 16 comprises an activation button 8 adapted for establishing fluid connection between the second compartment 4 and the first compartment 6 that contains a fluid (e.g. a preparation or saline for being mixed with a preparation). The first compartment 6 is configured to receive a fluid (e.g. medicine) through an inlet port 10' provided at the activation unit 16. Likewise, the second compartment 4 is configured to receive a fluid (e.g. medicine) through an inlet port 10 provided at the activation unit 16. The activation button 8 is provided at the lowest portion of the wall member 20 and is configured to establish an opening between the first compartment 6 and the second compartment 4.
Fig. 2 A illustrates a schematic view of a fourth embodiment of an IV bag 2 according to the invention. Fig. 2 B illustrates a schematic view of a fifth embodiment of an IV bag 2 according to the invention, and Fig. 2 C illustrates a schematic view of a sixth embodiment of an IV bag 2 according to the invention.
The IV bags 2 comprise a plurality of compartments 4, 6, 6', 18 defined by an upper portion 26 and lower wa!l(s) 28, 28' connected by a first outer wall 22 and a second outer wall 24, respectively. A suspending hole 14 is provided in the upper portion 26.
Referring now to Fig. 2 A, it can be seen that the IV bag 2 comprises a second compartment 4 for a rinsing fluid and a first compartment 6 for a crystalloid fluid which may be saline. The second compartment 4 is arranged above the first compartment 6. A wall member 20 separates the first compartment 6 and the second compartment 4. The wall member 20 has two sections: a left section which is angled relative to horizontal (with an angle relative to horizontal H) and a right section which is angled relative to horizontal (with an angle relative to horizontal H) when the IV bag 2 is suspended.
The IV bag 2 comprises an activation unit 16 provided at the central portion of the wall member. The activation unit 16 comprises an activation button 8 adapted for establishing fluid connection between the first compartment 6 and the second compartment 4. The angled sections make it possible for the fluid in the second compartment 4 to flow into the first compartment 6 through the opening provided by means of the activation button 8. The first compartment 6 is configured to receive a fluid (e.g. medicine) through an inlet port 10 provided at the activation unit 16.
The lower wall comprises a left section 28 which is angled relative to horizontal (with an angle β relative to horizontal H) and a right section 28' which is angled relative to horizontal (with an angle β' relative to horizontal H) when the IV bag 2 is suspended. Accordingly, the fluid in the first compartment 6 can be emptied through the outlet port 12 provided at the junction between the end of the left section 28 and the right section 28'.
The IV bag 2 illustrated in Fig. 2 B almost corresponds to the one shown in Fig. 1 A. The activation button 8, however, is arranged differently. The activation button 8 does not protrude parallel to the inlet port 10 like in the embodiment shown in Fig. 1 A.
Fig. 2 C shows an embodiment of an IV bag 2 according to the invention. The IV bag 2 comprises a plurality of compartments 4, 6, 6', 18 defined by an upper portion 26 (provided with a suspension hole 14), two lower wails 28, 28', a first outer wall 22 and a second outer wall 24.
The left lower wail 28 is angled relative to horizontal (with an angle β relative to horizontal H) and the right lower wall 28' is angled relative to horizontal (with an angle β' relative to horizontal H) when the IV bag 2 is suspended. Therefore, the fluid in the first compartment 6 can be emptied through the outlet port 12 provided at the junction between the end of the left lower wall 28 and the right lower wall 28'.
The second compartment 4 is configured to be brought into fluid communication with the first compartment 6 by means of an activation button 8 provided in an activation unit 16 extending along a portion of the first outer wall 22 and a portion of the wall member 20. Since the major portion of the wail member 20 is angled (with an angle relative horizontal H), the fluid in the second compartment 4 can (by means of gravity) flow into the first compartment 6 when an opening is established by means of the activation button 8 (e.g. a push button or a rotatable button).
The IV bag 2 comprises a third medical substrate compartment 18 filled with a substrate and a fourth compartment 6' containing a crystalloid fluid (e.g. saline) or sterile water. A thin membrane 30' divides the third compartment 18 and the fourth compartment 4'. Likewise, a thicker membrane 30 separates the first compartment 6 and the third compartment 18 and the fourth compartment 4'.
The thin membrane 30' is configured to be ruptured when squeezed from the outside. Likewise, the thick membrane 30 is configured to be ruptured when squeezed, although by a larger force, from the outside. Accordingly, the sequence of the rupture process can be controlled so that the thin membrane 30' ruptures before the thicker membrane 30.
When applying this IV bag 2, there is no need for injecting a preparation (e.g. medicine) into the first compartment 6. Accordingly, the IV bag 2 increases the safety of the healthcare practitioners carrying out IV treatment. As no preparation (e.g. medicine) needs to be added to the first compartment 6 by means of an injection, the patients and the healthcare practitioners carrying out IV treatment will not be exposed to airborne contaminants. Accordingly, allergies and eczema among patients and healthcare practitioners may be reduced.
More activation units may be provided to establish fluid communication between the compartments. Such activation units may contain various types of activation members. The activation members may be configured to establish fluid connection between the compartments upon being displaced, pulled or pushed in one or several directions e.g. sideways. The activation members may be any suitable member capable of establishing fluid connection between the compartments upon being activated either manually or electrically by using any suitable electrical activation means including automatic electric activation means.
