Abstract

An injection aid for supporting a hypodermic syringe and for facilitating injection of the needle of the syringe into a limb. The apparatus includes a syringe supporting member and a pair of guide rods for supporting the syringe supporting member for slideable movement between a first position wherein a needle supported by the syringe supporting member is retracted from the limb and an injecting position. A pair of spaced apart generally parallel support rods are also provided. The rearward ends of the support rods being adapted to rest on the limb and are integrally joined to the guide rods and for supporting the guide rods. The support rods include forward ends for pinching flesh therebetween to cause the flesh adjacent the syringe needle to pucker.

Claims

1. Apparatus for supporting a hypodermic syringe to facilitate injection of the needle of the hypodermic syringe into a limb, the apparatus comprising

a syringe supporting member having a syringe supporting surface adapted to support a syringe,

guide means for supporting the syringe supporting member for movement between a first position wherein the needle of the syringe is retracted from the limb and an injecting position, said means for supporting including a pair of guide rods for supporting said syringe supporting member for slideable movement between said first position and said injecting position, and

means for supporting said guide means on the limb and for pinching the flesh adjacent the syringe needle, said means for supporting said guide means including a pair of spaced apart generally parallel support rods having rearward ends adapted to rest on the limb and being integrally joined to said guide means, and said support rods including forward ends for pinching flesh therebetween to cause the flesh adjacent the syringe needle to pucker, and spring means for resiliently biasing said forward ends of said support rods together so as to cause said support rods to pinch the flesh therebetween.

2. Apparatus as set forth in claim 1 wherein said means for supporting said guide means further includes clamping means for clampingly engaging the limb, said clamping means including arms adapted to be positioned on opposite sides of the limb and to clampingly engage the limb, one of said arms being integrally joined to said forward end of one of said support rods, and the other of said arms being integrally joined to said forward end of the other of said support rods.

3. Apparatus as set forth in claim 1 wherein said guide rods each include a forward end and a rearward end, and wherein said rearward end of one of said guide rods is integrally joined to said rearward end of one of said support rods by a first rod portion extending transversely to said one of said guide rods and wherein said rearward end of the other of said guide rods is integrally joined to said rearward end of the other of said support rods by a second rod portion.

4. Apparatus as set forth in claim 1 and wherein said guide rods each include a forward end and a rearward end and wherein said rearward ends of said guide rods are spaced from said rearward ends of said spaced parallel rods and wherein said forward ends of said guide rods are closely adjacent said forward ends of said support rods.

5. Apparatus as set forth in claim 1 wherein said guide rods and said spaced parallel support rods are comprised of a one piece continuous elongated member.

6. Apparatus as set forth in claim 1 and further including means for fixing said rearward ends of said support rods in spaced apart relation.

7. Apparatus as set forth in claim 6 wherein said guide rods include forward ends and rearward ends and wherein said means for fixing provides means for fixedly supporting said rearward ends of said guide rods in parallel spaced apart relation.

8. Apparatus as set forth in claim 7 and further including a transverse rod integrally joining said forward ends of said guide rods.

9. Apparatus as set forth in claim 1 and further including resilient means for biasing said syringe supporting member toward said injecting position.

10. Apparatus as set forth in claim 9 and wherein said resilient means includes a coil spring surrounding one of said guide rods.

11. Apparatus as set forth in claim 10 wherein said guide rods include forward ends and rearward ends, wherein said guide means includes a transverse member positioned adjacent said rearward ends of said guide rods and fixedly supporting said guide rods in spaced apart relation, and further including means for releasably restraining said syringe supporting member in said first position.

12. Apparatus as set forth in claim 11 wherein said means for releasably restraining includes a lever having a forward end fixed to said syringe supporting member and a rearward end including means for releasably engaging said transverse member, said lever restraining said syringe supporting member in said first position when said rearward end of said lever engages said transverse member.
