Abstract

Disclosed herein is an injection device with housing that defines a channel and a first injection guide opening. The first injection guide opening enters the channel in a manner that allows a needle to penetrate a vessel in an animal with accuracy and at the same time protect the user from the needle.

First claim

What is claimed is:

1. An injection device comprising
a) a housing defining an arcuate channel and a first injection guide opening, the arcuate channel having a central axis, the first injection guide opening surrounding a first injection axis, wherein the first injection guide opening extends linearly to the arcuate channel, wherein the housing comprises
i) first and second end surfaces that are spaced apart relative to a first housing axis;
ii) a base surface extending between the first and second end surfaces; and
iii) at least one upper surface extending between the first and second end surfaces, wherein the base surface and the at least one upper surface are spaced apart relative to a second housing axis that is perpendicular to the first housing axis;

wherein the arcuate channel of the housing extends from the first end surface to the base surface,
wherein the first injection guide opening is positioned in fluid communication with the arcuate channel, and

wherein the first injection axis is substantially parallel to the first housing axis or the second housing axis.

2. The injection device of claim 1 , wherein the housing further defines a second injection guide opening surrounding a second injection axis, wherein the second injection guide opening is positioned in fluid communication with the arcuate channel, and wherein the second injection axis is substantially parallel to the first housing axis or the second housing axis.

3. The injection device of claim 2 , wherein the first injection guide opening extends from an upper surface of the at least one upper surface to the arcuate channel, wherein the first injection axis is substantially parallel to the first housing axis, wherein the second injection guide opening extends from an upper surface of the at least one upper surface to the arcuate channel, and wherein the second injection axis is substantially parallel to the second housing axis.

4. The injection device of claim 2 , wherein at least a portion of the central axis of the arcuate channel is substantially parallel to the second injection axis.

5. The injection device of claim 4 , wherein the at least a portion of the central axis that is substantially parallel to the second injection axis is spaced apart from the second injection axis relative to the second housing axis at a distance from about 0.8 mm to about 1.4 mm.

6. The injection device of claim 2 , further comprising a first injection insert guide that is at least partially received within the first injection guide opening, wherein the first injection insert guide surrounds the first injection axis.

7. The injection device of claim 2 , further comprising a second injection insert guide that is at least partially received within the second injection guide opening, wherein the second injection insert guide surrounds the second injection axis.

8. The injection device of claim 1 , wherein the first injection guide opening extends from an upper surface of the at least one upper surface to the arcuate channel, and wherein the first injection axis is substantially parallel to the first housing axis.

9. The injection device of claim 1 , wherein the first injection guide opening extends from an upper surface of the at least one upper surface to the arcuate channel, and wherein the first injection axis is substantially parallel to the second housing axis.

10. The injection device of claim 1 , wherein the first injection guide opening extends from the second end surface to the arcuate channel, and wherein the first injection axis is substantially parallel to the first housing axis.

11. The injection device of claim 1 , wherein at least a portion of the central axis of the arcuate channel is substantially parallel to the first housing axis.

12. The injection device of claim 1 , wherein the arcuate channel has a width from about 2 mm to about 5 mm.

13. The injection device of claim 1 , wherein at least a portion of the central axis of the arcuate channel is substantially parallel to the first injection axis.

14. The injection device of claim 13 , wherein the at least a portion of the central axis that is substantially parallel to the first injection axis is spaced apart from the first injection axis relative to the first housing axis at a distance from about 0.8 mm to about 1.4 mm.

15. The injection device of claim 1 , wherein the arcuate channel is an enclosed arcuate channel.

16. The injection device of claim 15 , wherein the enclosed arcuate channel is configured to receive at least a portion of a tail of a rodent.

17. The injection device of claim 1 , wherein the arcuate channel is at least partially open.

18. A method comprising
a) providing the injection device of claim 1 ;
b) placing a body portion of an animal in the arcuate channel; and
c) administering a substance to or withdrawing a fluid from a vessel in the body portion of the animal via a needle placed through the first injection guide opening.
