Abstract
Apparatus for supplying a patient with a fluid from a container (1) having a memory device (2) associated therewith. The memory device contains information relating to the contents of the container, such as the nature of the contents and the volume remaining within the container. Means (6) are provided for monitoring a body parameter indicative of the patient's condition and further means are provided for storing information defining the rate of flow of various fluids required for various body conditions. A processor reads the information contained in the memory device and the stored information actuates a flow control device (4) associated with the container in accordance with signals supplied by the monitoring means.
Description
FLUID DELIVERY APPARATUS
This invention relates to fluid delivery apparatus and in particular to apparatus for delivery of a fluid to a patient, eg. in the course of treatment. Examples of such fluids include blood, plasma, saline solutions, drug formulations, insulin, stimulants, and anaesthetics.
It is often desirable to control the flow of fluid to the patient in response to some parameter indicative of the patient's condition: examples of such parameters include respiration rate, pulse, blood pressure, brain activity, temperature, and the composition of a body fluid eg. exhaled breath, urine, or blood.
However, there is often a risk of error; for example supply of the wrong fluid to the patient and/or supply of the wrong quantity of fluid and/or supply at the wrong rate. This risk may be compounded by possible variation in the nature of the fluid eg. differing blood groups, drug formulations of differing concentrations and the like.
We have devised apparatus whereby such risks can be minimised.
Accordingly the present invention provides apparatus for supplying a patient with a fluid comprising means for monitoring a parameter indicative of the patient's body condition, a container having a memory device associated therewith, the memory device
containing information relating to the contents of the container, means for connection to said container for delivery of fluid from said container to the patient, flow control means for controlling the flow of fluid from said container to said patient, and means for reading the information stored in the memory device, whereby the flow control means can be operated in accordance with the read information and the signal derived from the monitoring means. It is seen that an important feature of the invention is the provision of an information carrying memory device associated with, and preferably attached to, the container. This memory device is coded with information relating to the contents of the container. Such containers are described in our European Patent Application No. 83300035 (Publication No. 00086029), the disclosure of which is incorporated herein by reference. The memory device is preferably an active electronic memory device, preferably digital, eg. a micro-chip, such as a PROM.
The flow control means may be a simple on/off valve or may be a proportional valve whose setting is determined by the monitored parameter in conjunction with the information carried by the memory device. The flow control means may be incorporated in the container or, alternatively, may be incorporated in the means for connection to the container for delivering the fluid to the patient.
The invention will now be described, by way of example, with reference to the accompanying drawings, in which:-
Figure 1 is a diagrammatic representation of an apparatus according to the invention; and
Figure 2 is an axial section of a container fitted with a memory device and a connector to the fluid delivery means. In Figure 1 there is shown a container 1 having a memory device 2 associated therewith. The type of information that may be carried by the memory device 2 includes not only the precise nature of the fluid within the container 1, but also the optimum delivery rate for a given value of a relevant body parameter. Also a security code may be provided so that delivery of the fluid can only take place when the relevant body parameter is being monitored and has a value within a particular range. The memory device 2 may also carry information regarding the amount of fluid remaining within the container 1 so that a warning signal can be given when the container approaches exhaustion of its contents.
An outlet port 3 of container 1 is connected to a fluid flow control device 4 for delivering fluid to a patient (not shown) via a line 5. A monitor 6 is provided to monitor one or more relevant body parameters of the patient. The memory device 2 is read by a control unit 7 which also receives signals from the monitor 6. The unit 7 contains a processor which operates in accordance with a program stored therein. Associated with the processor is a store for information defining the flow rates of various fluids required by patients according to age and other factors and according to the existing value of the body parameter, as monitored by the monitor 6.
In response to the information read from the memory device 2 indicating the precise nature of the fluid in container 1 and optimum delivery rates for any given value of a relevant monitored body parameter, the information stored in the processor of the unit 7, and the signals from monitor 6, the unit 7 supplies actuating signals to the fluid flow control device 4 to vary, as appropriate, the fluid delivered to the patient.
In Figure 2 the container 209 is shown inverted, having a cap 229 which is of a resilient plastic material which can sealingly grip the edge 223 of the container opening. The cap is fitted with an outlet port 234 and a vent inlet 235. Inside the supply outlet 234 is a shaped sealed ring 236, formed of rubber or like material. A sealing plate 237 is urged against sealing ring 236 by compression spring 239 the other end of which abuts a circumferential flange 240 within the upper end of outlet 234. Secured inside the vent inlet 235 and extending toward the upper end of the container 209 is an elongate duct 241, at the inner end of which is a springloaded ball valve 242, sealing the duct 241 against leakage of fluid from within container 209, but permitting air to enter container 209 when the pressure differential is sufficient to overcome the spring-loading of ball valve 242. The cap 229 also carries a memory device in the form of a pre-coded microcircuit chip 214 mounted to communicate via external conductive socket connections 243. The outer edge of cap 229 carries a thread 247, and for transport and storage carries a protective threaded cap lid (not shown).
The container 209 is mounted on the system via the connector 230, shown immediately below it. This comprises a cover member 244 formed with a flanged edge 245 supporting a freely rotatable threaded collar 246 which can engage with thread 247 to hold cover member 244 and cap 229 tightly together. Cover member
244 is formed with a projecting supply pipe 248 to mate with outlet 234, a projecting vent pipe 249 to mate with vent outlet 235 and female electrical contacts 251 to mate with male sockets 243. Connections 215 from contacts 251 lead to the memory reading device. Pipe 248 projects to a height sufficient so that, when cap 229 and cover 244 are in close contact, sealing plate 237 is lifted off sealing ring 236 so the fluid can flow out around the edges of plate 237 (which for this purpose are preferably partly cut away) into pipe 248. It will be appreciated that the apparatus described with reference to Figure 1 can be modified by removing the store associated with the processor unit 7 and the connection between the unit 7 and the fluid control device 4. In this event, the unit 7 is provided with a display for information regarding the amount of fluid remaining in the container 1, derived from the memory device 2, and for the value of the body parameter, derived from the monitor 6. A doctor or nurse then manually adjusts the flow control device 6 in accordance with known information relating to the flow rate required and the patient's body condition.
