Abstract

The present invention relates to an improved quantitative skin allergic test device, which has a finger grip to be held by fingers and multiple legs longitudinally attached to the finger grip. Each leg has a cover having a sealing plug portion adaptful for the mouth of an antigen container, an elongated stem extending from the sealing plug portion, and a raised portion as well as a plurality of punctures provided at the end of the elongated stem. The raised portion and punctures being capable of carrying sufficient antigen liquid therebetween to conduct the test. The raised portion may be act as a stop to limit excessive penetration of the punctures, therefore preventing the epidermis layer of the skin of a patient from being penetrated through while conducting a skin allergic test so as to obtain an accurate interpretation of the test result.

Claims

1. A multileg skin-allergic testing device of the type that includes a rectangular-plate-like finger grip and a plurality of legs longitudinally attached to the finger grip to form an integral body, wherein each leg is furnished with a plurality of punctures at an end thereof;

wherein each of said legs being provided with at least a raised portion at the same end as where the puncturers are applied into a human skin, said raised portion is in a spaced apart relationship with respect to said puncturers to act as a stop, each of said puncturers having a length greater than the height of said raised portion by a predetermined value which is less than the thickness of the epidermis layer of the human skin, so that each puncturer will not penetrate through the epidermis layer of the skin of a human due to said raised portion being acting as a stop during a skin allergic test.

2. The multileg skin-allergic testing device of claim 1, wherein each said leg further comprises an integral cover which has a sealing plug, said cover being located between said finger grip and the punctures while said sealing plug being located between the cover and the punctures, the sealing plug having a diameter greater than that of the stem but less than that of the cover, said sealing plug being adapted to a mouth of an antigen container to prevent the antigen liquid in said antigen container from being contaminated.

3. The multileg skin-allergic testing device of claim 2, wherein each said cover of the leg further has an O-ring furnished on an outer rim thereof such that when the sealing plug is plugged into the antigen container, the O-ring will seal the outer surface of the mouth of the container to perform better sealing effect.

4. The multileg skin-allergic testing device of claim 1, wherein each said leg further comprises an elastic portion for accommodating deflection and deformation of the leg.

5. The multileg skin-allergic testing device of claim 4, wherein each said leg further comprises a cover while said elastic portion is formed between said cover and said raised portion.

6. The multileg skin-allergic testing device of claim 4, wherein each said leg further comprises a cover while said elastic portion is formed between said cover and said finger grip.

7. The multileg skin-allergic testing device of claim 4, wherein said elastic portion of the leg is formed by making part of the leg thinner and twisted in a wave-like manner such that, in comparison with other part of the leg, a relatively larger deflection and deformation can be Performed by the elastic portion.

8. The multileg skin-allergic testing device of claim 4, wherein said elastic portion of the leg is formed by making part of the leg thinner and twisted in a screw-like manner such that, in comparison with other part of the leg, a relatively larger deflection and deformation can be performed by the elastic portion.

9. A skin allergic testing device comprising:

a multileg skin-allergic testing device having a rectangular-plate-like finger grip, multiple legs longitudinally attached to the finger grip to form an integral body and a plurality of punctures furnished at an end of each of said legs;

each of said legs being provided with at least a raised portion at the same end where the punctures being furnished, said raised portion is in a spaced apart relationship with respect to said punctures to act as a stop, each of said punctures having a length greater than the height of said raised portion by a predetermined value which is less than the thickness of the epidermis layer of human skin;

a plurality of antigen containers, each of said containers having an inner compartment for storing antigen solution and a top mouth for receiving a leg of the multileg skin-allergic testing device; and

a tray having a plurality of round holes formed thereon, each of said round holes being capable to receive one of said antigen containers, the amount and positions of the round holes being so designed that, when taking said multileg skin-allergic testing device to mate with said tray, the legs of the multileg skin-allergic testing device are exactly put into the antigen containers which are received in the round holes of the tray.

10. The skin allergic testing device of claim 9, wherein each said leg of said multileg skin-allergic testing device further comprises an integral cover which has a sealing plug, said cover being located between said finger grip and the punctures while said sealing plug being located between the cover and the punctures, the sealing plug having a diameter greater than which of the stem but less than which of the cover, said sealing plug being adaptful to the mouth of the antigen container to prevent the antigen liquid in said antigen container from being contaminated.

11. The skin allergic testing device of claim 9, wherein two opposite sides of the tray are formed with a male connecting mechanism and a female connecting mechanism respectively, such that several trays can be assembled one by one by means of the connecting mechanisms for facilitating allergy tests especially when a vast amount of tests using various kinds of antigen solutions are needed.

12. The skin allergic testing device of claim 9, wherein each said cover of the leg further has an O-ring furnished on an outer rim thereof such that when the sealing plug is plugged into the mouth of the antigen container, the O-ring will seal the outer surface of the mouth to perform better sealing effect.

13. The skin allergic testing device of claim 9, wherein each said leg further comprises an elastic portion for accommodating deflection and deformation of the leg.

14. The skin allergic testing device of claim 13, wherein each said leg further comprises a cover while said elastic portion is formed between said cover and said raised portion.

15. The skin allergic testing device of claim 13, wherein each said leg further comprises a cover while said elastic portion is formed between said cover and said finger grip.

16. The skin allergic testing device of claim 13, wherein said elastic portion of the leg is formed by making part of the leg thinner and twisted in a wave-like manner such that, in comparison with other part of the leg, a relatively larger deflection and deformation can be performed by the elastic portion.

17. The skin allergic testing device of claim 13, wherein said elastic portion of the leg is formed by making part of the leg thinner and twisted in a screw-like manner such that, in comparison with other part of the leg, a relatively larger deflection and deformation can be performed by the elastic portion.
