Abstract

Delivery devices for administering drugs are disclosed. An example apparatus, includes a body including: a handle in which a syringe assembly is to be disposed; a base having a bottom face to be disposed adjacent a user; and an absorbent material attached to the bottom face, the absorbent material structured to hold a fluid to be released onto the user prior to or during an injection procedure.

First claim

The invention claimed is:

1. An apparatus, comprising:
a body including:
a handle in which a syringe assembly is configured to be disposed;
a base having a bottom face configured to be disposed adjacent a user; and
an absorbent material coupled with the bottom face, the absorbent material structured to hold a fluid to be released onto the user prior to or during an injection procedure,

wherein the absorbent material is structured to deter the base from moving during the injection procedure,
wherein the fluid is at least one of: (a) a sterilization fluid, (b) a friction-generating substance, and (c) a numbing agent, and
further including a housing in which the absorbent material is disposed, the housing to deter the fluid from evaporating prior to the injection procedure.

2. The apparatus of claim 1 , wherein the housing includes a housing skin surrounding one or more sides of the absorbent material.

3. The apparatus of claim 1 , further including a movement-resistant material, the movement-resistant material to surround at least a portion of the absorbent material.

4. The apparatus of claim 3 , wherein the movement-resistant material includes an annular cross-section.

5. The apparatus of claim 1 , further including a release layer covering an exterior surface of the absorbent material to deter contaminants from being exposed to the absorbent material.

6. The apparatus of claim 1 , further comprising the syringe assembly, wherein the syringe assembly includes a needle structured to penetrate the absorbent material prior to or during the injection procedure.

7. The apparatus of claim 1 , further comprising the syringe assembly, wherein the syringe assembly includes an actuator that is structured to move a needle of the syringe assembly from a retracted position to an extended position during the injection procedure, in the extended position, the needle to extend from the base.

8. The apparatus of claim 7 , wherein the actuator is triggered in response to the absorbent material being compressed or the actuator is carried at an end of the handle.

9. The apparatus of claim 1 , wherein the base is structured to receive and move relative to the handle, the base including a needle guard that enables the needle to extend from the base during the injection procedure.

10. The apparatus of claim 9 , further including a spring disposed between the base and the handle to bias the needle guard toward an extended position.

11. The apparatus of claim 1 , the housing comprising a layer surrounding sides of the absorbent material, wherein the layer includes at least one of a low-tack adhesive or a non-slip coating.

12. The apparatus of claim 1 , wherein the absorbent material has an open-cell arrangement.

13. The apparatus of claim 1 , further comprising a needle guard carrying the absorbent material.

14. The apparatus of claim 13 , further comprising a biasing element disposed between the handle and the needle guard.
