ADMINISTRATION SET Filed June 27, 1958 INVENTOR. 25 CHA V//V C. COU/LEV El a, BY -85 Z5 /5 United States Patent Oiice 3,057,350 Patented Oct. 9, 1962 3,057,350 ADMINISTRATN SET Calvin C. Cowley, La Canada, Calif., assignor to Don Baxter, Inc., Glendale, Calif., a corporation of Nevada Filed .lune 27, 1958, Ser. No. 745,168 8 Claims. (Cl. 12S- 214) This invention relates to an administration set for parenteral solutions and particularly to a set for administering intravenous anesthetics.

In the administration of an intravenous anesthetic, such as sodium thiopental, the usual procedure is t first infuse saline or dextrose solution. The intravenous anesthetic agent is then administered from a hypodermic syringe by inserting the syringe needle through a rubber tube near the patient end of the administration set. This arrangement may cause trouble however, because the rubber gland tends to leak when the needle is withdrawn. Even more serious, is the tendency of the syringe plunger to creep. This may cause 4the patient to receive too much anesthetic, or infusion solution may enter the syringe thereby diluting the anesthetic agent. Both of these possibilities are obviously highly undesirable.

Metal stopcocks, known to the trade as three-way stopcocks, have been used to control the administration of anesthetic agents and infusion solutions. Such stopcocks are expensive and extremely diflicult to clean and they cannot be used to administer more than one solution at a time.

It is the general object of this invention to provide an improved, expendable administration set for administering intravenous anesthetics.

Another object of the invention is to provide an administration set for 'administering two solutions either alternately or simultaneously.

Another object of the invention is to provide a set for administration of intravenous anesthetic which will prevent diffusion or dilution of the anesthetic.

Another object of the invention is to provide an administration set for administering three different solutions.

A further object of the invention is to provide an administration set for intravenous anesthetics in which the anesthetic reaches the patient with a minimum of delay yafter it is introduced into the set.

A still further object of the invention is to provide an administration set in which auxiliary medication, such as curare or a stimulant, can be `administered without disturbing the administration of infusion or anesthetic solutions.

A still further object of the invention is to provide an inexpensive, expendable administration set having a lightweight valve or stopcock, the plug of which will not come loose, even during pressure administration.

The administration set of the present invention will.

be more fully understood from the description of the preferred form of the invention given with the accompanying drawings, in which:

FIGURE l is a plan View of the invention including the connector 10.

FIGURE 2 is a sectional view of the connector 10.

FIGURE 3 is a sectional view on the line 3 3 of FIGURE 2.

FIGURE 4 is a sectional view on the line 4-4 of FIGURE 2.

FIGURE 5 is a sectional View on the line 5-5 of FIGURE 2.

FIGURE 6 isa partial view in section of a modification.

Referring now to the drawings, the administration set has a connector generally indicated as 10, a small diameter flexible tube 11 and a needle adapter 12. The connector l0 has a body 13 through which 'a bore 14 passes. The upper portion of the bore 14 has a tapered surface 15. At the top of the body 13, an annular ange 16 projects outwardly. The ilange has a flat horizontal bottom surface 17 and an outer surface 18 which tapers inwardly toward the top. At the lower end, the bore 14 tapers inwardly along the surface 19 to a relatively small outlet tube 20 which is connected by the small flexible tube l1 to one end of the needle adapter 12. The adapter 12 has a flange 21, ya tapered extension 22 adapted to receive the hub 23 of the needle 23a and a protector hub 24.

Near the middle of the body 13, cross tubes 25 and 26 project outwardly on opposite sides, preferably at right angles to the body. The tubes 25 and 26 are provided with bores 27 and 28 having tapered surfaces 29 and 30 which are adapted to receive a Luer or other standard, male, needle adapter. At the junctions of the bores 27 and 28 with the bore 14 partial diaphragms 35 projecting into the bores 27 and 2S form the rectangular openings 31 and 32.

The tapered bore 14 is preferably adapted to receive a rotatable valve member 40. The valve member 40 has a tapered plug 41 and a top section 42, the latter extending beyond the body 13 when the plug 41 is placed in the bore 14. A bore 43 extends through the valve member 4t) and is provided at its lower end with an opening 44 restricted and reinforced by the ledge 45. At the other end, the bore 43 has a tapered inner surface 46 adapted to receive a needle adapter. A removable, resealable rubber stopper 47, having a plug 48, and a skirt 49 closes this end of the bore 43. On one side, the tapered plug 41 has a slot 51 the sides 52, 53 of which meet the -bottom iiat wall portion 57 at substantially right angles. The upper end of the slot 51 is closed while the lower end has an opening 55. The bore 43 adjacent the upper end of la slot 51 has a slanting surface 56 extending inwardly on one side to form at wall portion 57.

The top section `42 of the valve member 40 has a horizontal flange 5S extending outwardly and adapted to serve as a valve handle. In the preferred design, the flange 58 -is provided with an arrow-like point 69 indicating the position of slot 51. Retaining hooks for holding the valve plug 41 in the connector body 13 are provided by the arms 59 which extend downwardly from ange 58 and hooks 61 and 62 which extend inwardly from arms 59. The hooks 61 and 62 have slanted inner edges 63 and 64 and flat horizontal surfaces 615 and 66. Above the hooks 61 and 62, holes 67 and 68 pass through flanges 58.

As shown in FIGURE 6, the lower end of the bore 43 may be provided with ia check valve unit 80 having a body 81, one end of which has a valve seat 82 and the other end a restricted outlet 83. The seat 82 has a tapered surface 84. A spring 85 holds the ball 86 against the tapered seat 84 except when fluid pressure in the bore 43 forces the ball down and opens the v-alve.

Both the body 10 and the valve member 40` are preferably molded of plastic material. Nylon has been found particularly suitable because of its moldability, strength, and resilience, but polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other plastics can be used. The arms 59 and the hooks 61 and '62 of valve member 40 require more strength and resilience than other parts of the structure, and when included in the structure, may limit the usable materials somewhat.

In use, a bottle of infusion solution is connected by an administration set 91 to tube 26 of the connector 10. The administration set may be provided with a drip indicator 92 and a clamp 93 or other ow control device. A syring 94 is filled with a solution of anesthetic suitable for intravenous use and is connected to the tube 25. The

3 flange 58 is then tur-ned till the slot 51 connects with the bore 28 and infusion solution is allowed to flow from bottle 90 through the set 91, the bore 28, the slot 51, the outlet tube 20, the fiexible tube 11, the adapter 12, and the needle 23a into the veins of the patient.

To administer anesthetic, the flange 58 is turned until the slot 51 connects with the bore 27. A measured amount of anesthetic solution is then forced from the syringe through the bore 27, the slot 51 and the tube 11. The flange 58 is then turned back to connect with the bore 28, and administration of the infusion solution is resumed.

If for any reason additional medication is needed, it may be injected from a syringe through the stopper 47 into bore 43. For example, it might be desirable to inject a stimulant quickly in an emergency, or to inject a muscle relaxing agent such as curare or succinylcholine chloride without interfering with the liow of infusion solution or anesthetic. After the injection is made, the syringe needle may be withdrawn and the stopper 47 reseals around the needle puncture. Alternatively the stopper 47 may be removed and a male needle adapter inserted in the tapered bore 43.

Alternatively the infusion solution may be connected to the bore 43, anesthetic agent to the bore 27 and muscle relaxant to the bore 28. In this way the infusion solution flows continuously through the bore 43. Anesthetic or relaxant is added to the continuous fiow as needed, by turning the valve member 40.

In the modification shown in FIGURE 6, a check valve 80 normally closes the bore 43 so that solution cannot escape during manipulations. When pressure is applied to the -solution connected to bore 43, the ball 86 is forced away from the tapered seat 84 allowing solution to liow through to the patient.
