Abstract

Apparatus is provided for intravenous administration of a series of solutions for cardiopulmonary resuscitation. Each solution is in a separate syringe held in place on a base plate. All syringes are connected at the same time to a single stopcock with multiple inlets and a single outlet for connection via tubing to a needle in the patient'"'"'s vein. A selector handle on the stopcock is rotated to a particle inlet to select the solution in a particular syringe. The assembly eliminates the changing of syringes, the confusion and errors, and the need for assistance of the prior apparatus and speeds up the administration of the medications to make the treatment more effective, and, more importantly, reduces the risk of bacterial contamination.

Claims

1. An assembly for facilitating the intravenous administration of a series of medications for cardiopulmonary resuscitation, comprising:

a supporting base means for supporting all the necessary elements of the administration in position for most effective use;

a plurality of syringe holding means connected to the surface of said base means for holding a plurality of syringes containing said medications and a flushing solution in convenient positions ready for use;

a stopcock held in position on the surface of said base means, said stopcock having a plurality of inlet means, one for each of said medications and one for said flushing solution, said inlet means including syringe connecting means for connecting said stopcock to said syringe in leak-tight connection;

said stopcock further having a single outlet means, said outlet means including tubing connection means for connecting said outlet to intravenous tubing communicating with the vein of a patient, said stopcock further including manual position selection means for selectively connecting one of said inlet means with said outlet means so that a medication from a selected syringe can be injected into said patient by simple manual operation of said selection means said stopcock including means sealing said outlet means from said inlet means when said position selection means is not connecting one of said selected inlet means with said outlet means.

2. The assembly of claim 1, further including a plurality of syringe identification label means connected to said base means and located with relation to said syringe holding means to identify appropriately the contents of each syringe that will be placed on said base means to reduce errors.

3. The assembly of claim 1, further including a chart of recommended dosages for said medications for different body weights affixed to the surface of said base means to reduce errors.

4. The assembly of claim 2, further including syringes filled with said medications and said flushing solution and held in correct locations by said syringe holding means to provide a package ready for use in an emergency, said syringes including syringe sealing means for sealing in the syringe contents during shipment.

5. In the assembly of claim 1, said stopcock further comprising a tapered inner plug means and an outer barrel means, said plug means connected to said selection means at the upper end of said plug means, said plug means rotatably and sealably engaged in a tapered recess in said barrel means;

said barrel means having said plurality of inlet means arranged radially in a common plane, said barrel means further having said outlet means arranged radially at a plane below said inlet means, sid plug means including an axial bore extending through the bottom of said plug means at a first end, said bore connecting with a radial bore at a second end, said radial bore extending from said axial bore to the tapered lateral surface of said plug at a level corresponding to said common plane of said inlet means when said plug is sealably seated in said barrel so that said bore communicates with the inner fluid passage of each inlet means when said plug is selectively rotated about its longitudinal axis by said selection means, said barrel further including an axial bore below said tapered recess that is in registry with said axial bore in said plug means, said axial bore in said barrel is connected to a radial bore extending into said outlet means so that a fluid passage may be established from any one of said inlet means through said outlet means by the rotation of said selection means for the intravenous injection of the contents of the syringe connected to said inlet means.

6. The assembly of claim 5, further including plug tightening means said plug tightening means biasing said tapered plug into sealing relationship with said tapered recess in said barrel.

7. In the assembly of claim 6, said plug tightening means including a locking collar means connected to the upper end of said barrel.

8. In the assembly of claim 5, said plug is composed of a lubricous, resilient material for enhanced rotating and sealing.

9. The plug of claim 8 composed of a fluorocarbon plastic.

10. In the assembly of claim 1, said syringe connecting means including tubing means connecting said stopcock to said

syringe connecting means so that said syringe holding means and said syringes may be arranged on said base means in substantially parallel array for more compact arrangement and easier handling.

11. A stopcock for facilitating the intravenous administration of a series of medications for injection into a needle in a patient'"'"'s vein for cardiopulmonary resuscitation, comprising:

a tapered inner plug means;

a position selection handle connected to the top of said plug means for rotating said plug means;

an outer barrel means having an inner recess for receiving said plug means, said recess having an open top and a closed bottom, said recess having a taper matching said plug means to provide a rotating seal of said plug means in said recess;

said barrel means including a plurality of syringe-connecting inlet means arranged radially in a common plane about the longitudinal axis of said barrel means, each of said inlet means including a fluid passage extending to said recess, said barrel means further including an axial bore extending from said bottom of said recess to a radial bore extending outwardly to an outlet means with tubing connecting means for connecting to intravenous tubing that is connected to said needle in said patient'"'"'s vein;

said plug means including a fluid passage therethrough comprised of an axial bore extending from the bottom of said plug where said bore is in registry with the axial bore of said barrel means up to the level of said inlet means in said barrel means, said bore in said plug means then extending radially to the outer surface of said plug means where it may be positioned in registry with the fluid passage of any particular inlet means by rotation of said position selection handle so that a fluid passage may be established from any selected inlet means to said outlet means;

and plug tightening means connected to the top of said barrel means for forcing said plug means tightly into said recess to ensure liquid tight sealing of said plug means in said recess in said barrel.

12. In the stopcock of claim 11, said plug tightening means including a locking collar means.

13. In the stopcock of claim 12 said locking collar means including a tapered surface for snap-in fitting of said plug means.

14. In the stopcock of claim 11, said plug means is composed of a resilient, lubricous material for enhanced sealing and rotating.

15. The plug means of claim 14 composed of a fluorocarbon plastic.
