ANESTHESIA DOCKING STATION
Back~round of the Invention The present invention reIates to a device for improving connection to a patient of an anesthesia-delivering catheter and an infusion source for the anesthesia.
Epidural and continuous spinal anesthesia are common anesthetic techniques 10 used in operating rooms, hospital wards and in pain clinics. Such anesthetic techniques also find use by outpatients in homes for the treatment of chronic pain. Anesthesia is delivered to a patient through a thin, flexible catheter, the distal end of which penetrates the patient's body to deliver the anesthesia to a desired location, usually the epidural space. The proximal end of the catheter typically is connected to an infusion line that communicates with an infusion 15 source for deliverin2 the anesthesia to the catheter.
Currently, anesthesia is often delivered simply by joining together the infusionline and catheter and taping the joined unit to a tongue depressor, allowing the catheter to extend over the patient's shoulder and along the patient's back to a desired insertion point.
20 Such a connection arrangement is not satisfactory as it can often lead to catheter kinking or disconnection, possibly resulting in cont~min~tion of the epidural system and/or inadequate delivery of anesthesia. The increased use of epidural anesthesia in ambulating patients has resulted in an increased incidence of catheter disconnection, kinking and breaking, and system cont~min~tion.
Another potential hazard encountered with the use of such anesthesia delivery systems is the inadvertent injection into the epidural catheter system of substances intended for intravenous or other sites. Such errors can have life threatening consequences.
U.S. Patent ~o. 3,794,032 (Derouineau) discloses a connecting device in the forrn of a cuff mountable on a patient for effecting tranfusions or perfusions to a patient. The connecting device comprises a support base, mountable to the patient, and an adapter mechanism mounted on the support base. The adapter mechanism has at least one inlet port in fluid communication with an outlet port that is connectable ~o a catheter. A valve is 3 5 present on the adapter mechanism to regulate flow between inlet and outlet ports.
Accordin_ly, there is a need for a more secure and reliable anesthesia delivery svstem that effectively joins an infusion source to an epidural catheter svstem.

It is also an object to provide a device that facilitates safe and secure connection of an infusion source to a catheter system. Other objects of the invention will be apparent from the following description of the invention.

wo 94/23783 2 1 6 0 5 ~ ~ PcrluS94104095 Summaly of the Invention The invention provides a device for securely joining an infusion source to an S anesthesia-delivering catheter system. The device comprises a support base having an adapter mech~ni~m mounted on a top or first surface of the support base. The adapter mech~ni~m has at least a first port adapted to communicate with an infusion line, a second port adapted to communicate with an ~n.o5th~5j~-delivering catheter, and a valve means for regulating flow between the first and second ports. The device also includes a means for 10 relieving tensile strain on the anesthesia catheter. Preferably, a bottom or second surface of the support base includes a double sided adhesive material to facilitate mounting of the device to a patient.
The device is useful in the delivery of epidural and continuous spinal 15 anesthesia as it provides a secure connection between the infusion line and the catheter system and may also be comfortably affixed to a patient. This facilitates greater patient mobility, while at the same time reducing the risk of catheter breakage, catheter disconnection and catheter kinking. The device also enhances patient safety because the reduced risk of catheter breakage and catheter disconnection also reduces the risk of infection 20 due to cont~rnin~tion of the epidural system.
Tensile strain on the anesthesia catheter can be relieved by providing an adapter line which connects between the second port and the proximal end of the anesthesia-delivering catheter. The adapter line preferably is a stretchable or expandable conduit having 25 sufficient inner diameter to accommodate fluid flow. Preferably, the adapter line is a stretchable line having a coiled region.
Tensile strain on the catheter may also be reduced without connecting a stretchable adapter line between the second port and the catheter. In such an embodiment the 30 proximal end of the catheter can be connected directly to the second port. Further, a length of a proximal portion of the catheter is engaged by flanges or stanchions mounted on opposite ends of the top support base. In this way, slack can be created in the catheter line to relieve any tensile strain. Alternatively, a zone can be formed on the surface of the support base to engage a portion of a proximal length of the catheter to create slack in the catheter line.
In another embodiment the device further includes a third port in fluid communication with the first and second ports. The third port facilitates the delivery of medicaments (e.g., anesthetics) to the anesthesia-delivering catheter.

s Figure 2 is a perspective of the anesthesia docking station shown in Figure 1.
Figure 3 is an alternative anesthesia docking station useful with the present invention.
Detailed Description of the Invention As shown in Figure I, anesthesia docking system 10 of the invention comprises a docking station 12 that can be affixed to a patient 14. The system 10 comprises an infusion source (not shown) communicated through an infusion line 18 to the docking station 12. The infused fluid, such as an anesthesia-containing fluid, is communicated to a catheter line 22, the distal end thereof which delivers anesthesia to the epidural or the subarachnoid space of the patient. The system is best adapted for use in the delivery of epidural anesthesia and continuous spinal anesthesia.
Referring to Figures 1 and 2, docking station 12 comprises a support base 26 having mounted thereon an adapter mech~ni~m 28. Preferably, the adapter mechanism 28 is mounted upon a flange 31 such that it is positioned above the surface 29 of support base 26.
The adapter mech~ni~m 28 incudes a first port 30 adapted to communicate with infusion line 18 and a second a port 32 adapted to communicate with catheter 22. A third port 34 (shown in Figure 2) may also be mounted on the adapter mech~ni~m 28, intermedi~te first port 30 and second port 32. Third port 34 can be used to deliver medicament to the catheter line 22.
Ideally, port 34 includes at a top portion thereof a self-closing seal 35.
As illustrated in Figure 2, the first port 30 may be mounted on a flexible fluidcommunication line 36 that extends between port 30 and the adapter mechanism 28.Preferably, at least a portion of line 36 includes a coiled region 38 that enables extension of the line 36. Altematively, port 30 can be mounted directly on adapter mech~ni~m 28 as shown in Figure 3.
The proximal end of catheter 22 can be connected directly to second port 32 as illustrated in Figure 3. Altematively, as illustrated in Figure 2, the proximal end of catheter 22 can be connected to port 32 through a catheter adapter line 40. Catheter adapter line 40 has a proximal end 42 with a connector 44, such as a luer lock, friction fit connector, or J
216055~
threaded connector, for mounting to port 32. The distal end 46 of catheter adapter line 40 includes a standard connector 48 for mounting to catheter 22. Catheter adapter line 40 preferably is manufactured from a medically compatible polymeric material and has an inner diameter sufficient to accommodate fluid flow. Catheter adapter line 40 preferably includes a coiled region 50 that enables extension of line 40 and movement of catheter 22 without placing undue tensile strain on either catheter line 40 or catheter line 22. The length of catheter line 40 may vary depending upon requirements of a given application. Generally, however, the line is approximately 16 inches in length and coiled region 50 enables catheter adapter line 40 to be extended to at least 3 to 5 times its normal length.
The adapter mech~ni~m 28 preferably includes a valve 52, such as a stopcock, infusion port, or a similar device, to regulate fluid flow between the first and third ports and the second port.
Support base 26 is a rigid or flexible member having a shape and dimensions suitable to its intended application. This support member may, for example, be rectangular, oval or circular in shape. A suitable rectangular base 26 can have dimensions of about l 1/2 x 3 1/2 inches. One having ordinary skill in the art will appreciate that the d-imensions of the support base may be modified as necessary. A bottom surface 54 of support base 26 preferably includes an adhesive material or other means of mounting the support base to the skin of a patient. Preferably, a cushioned, two-sided adhesive 56 is placed on the bottom surface 54 of support base 26. A removable release sheet 58 preferably protects the adhesive surface of the adhesive layer 56 before use.
Figure 3 illustrates docking station 60, forrning an alternative embodiment of the invention. As illustrated, adapter mechanism 70 is secured by way of mounting flange 31 to a top surface 29 of support base 26. The adapter mech~nicm includes a first port 30, second port 32 and third port 34. The three ports mounted upon the adapter mechanism 70 in alternative docking station 60 serve the same purpose as the corresponding ports in docking station 12. However, port 30 communicates directly with catheter line 22. Docking station 60 also includes two stanchions 62 mounted on opposite ends of docking station 60.
Stanchions 62 are adapted to engage a proximal portion of catheter line 22 to provide slack in the catheter line and thus relieve any tensile strain on the catheter line ~2. In one embodiment, one stanchion may comprise a U-shaped flange 64 while the other comprises a vertical member 66 havïng a central aperture 68 disposed therein. As illustrated, the catheter may engage flange 64 and be threaded through aperture 68 of member 66 before being directed to a desired location on a patient's body. The threading of the catheter line through aperture 68 enables a desired arnount of slack to be created in catheter line ~2.
t~ D S~,, wo 94/23783 2 1 6 0 5 S 3 PcrluS94/04095 The docking system of the present invention is advantageous as it is able to be comfortably and securely affixed to a patient. At the same time, the infusion line may be securely joined with a catheter line to deliver an anesthetic to a patient. The connection of S the infusion line and the catheter line typically utilizes well known, reliable locking mech~nisms such as luer locks, friction fit connectors, or threaded connectors, and thus virtually elimin~tes any risk of nnintenrled disconnection of the catheter line from the infusion source. The docking station also provides a surface which can be clearly marked to indicate the intended use of the various ports to facilitate rapid and easy assembly.
10 Moreover, due to the secure ~tt~chment of the docking station to the patient and the secure connection between the infusion source and the catheter line, ambulatory patients in need of pain control treatments have greater freedom of movement.
Various modifications may be made in the device described above 15 without departing from the intended scope of the invention.
