Description

Technical Field

[0001] This utility model relates to the field of experimental technology, specifically a disposable puncture needle. Background Technology

[0002] Disposable prick needles are a commonly used tool for skin prick testing, which has gradually replaced traditional intradermal tests in allergen detection for allergic diseases. Specifically, the procedure involves dipping the tip of a disposable prick needle directly into a solution (i.e., reagent solution) and applying it to the skin. The dipped needle carries a small amount of antigen, which is then used to prick the skin, thus achieving the prick test. However, in traditional methods, the amount of reagent solution remaining on the disposable prick needle after each dilution is relatively small, affecting the accuracy of the test.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-5 As shown, the present invention provides a disposable puncture needle, which includes a handle rod 10, multiple branch rods 11 and multiple needle bodies 12.

[0024] The handle 10 is elongated. It should be understood that the handle 10 has raised friction points for easy gripping.

[0025] Multiple branch rods 11 are detachably spaced on the same side of the handle rod 10, allowing different branch rods 11 to be replaced as needed (e.g., damaged branch rods).

[0026] Preferably, multiple friction strips are provided at intervals on the branch rod 11 to increase friction and facilitate gripping.

[0027] In this embodiment, a plurality of receiving holes 101 are provided at intervals on the same side of the handle 10. A third magnet is provided in the receiving hole 101. The other end of the branch rod 111 is received in the receiving hole 101 and is provided with a fourth magnet that attracts the third magnet, so that the branch rod 11 is detachably connected to the handle 10 by magnetic attraction.

[0028] Of course, in other embodiments, a plurality of threaded holes are provided at intervals on the same side of the handle rod 10, and the outer wall of the other end of the branch rod 11 is provided with a threaded post that is threadedly connected to the threaded hole, so that the branch rod 11 can be detachably mounted on the handle rod 10 by means of threaded connection.

[0029] The needle body 12 is detachably located at the end of the branch rod 11 away from the handle rod 10, so that different models of needle bodies 12 can be replaced as needed.

[0030] In this embodiment, the cross-sectional area of ​​the end of the branch rod 11 away from the handle rod 10 is larger than the cross-sectional area of ​​the needle body 12, and the end of the branch rod 11 away from the handle rod 10 is provided with a plurality of protrusions 110 spaced apart from the needle body 12. It should be understood that since the cross-sectional area of ​​the end of the branch rod 11 away from the handle rod 10 is larger than the cross-sectional area of ​​the needle body 12, the reagent solution will remain in one end of the branch rod 11 after each application. This reagent solution will remain on the skin after the needle body 12 pricks the skin. Since the end of the branch rod 11 away from the handle rod 10 is provided with a plurality of protrusions 110 spaced apart from the needle body 12, these plurality of protrusions 110 can increase the contact area with the reagent solution, thus allowing a larger amount of reagent solution to remain on the pricking needle after each application, ensuring the effectiveness of the pricking test.

[0031] It should be understood that in some embodiments, the end of the branch rod 11 away from the handle rod 10 is also provided with an absorbent material layer corresponding to the protrusion 110, so that each time liquid is applied, the absorbent material layer absorbs the reagent liquid, allowing more reagent liquid to remain on one end of the branch rod 11.

[0032] Preferably, the absorbent material layer includes a sponge layer or other absorbent material layer.

[0033] In this embodiment, a receiving slot 111 is provided along the length direction of the end of the branch rod 11 away from the handle rod 10. The needle body 12 includes a locking part 121 and a needle part 122. The locking part 121 is detachably disposed in the receiving slot 111, and the needle part 122 is exposed outside the receiving slot 111.

[0034] Preferably, the receiving slot 111 is rectangular and the holding part 121 is rectangular, wherein the length, width and thickness of the receiving slot 111 are equal to the length, width and thickness of the holding part 121.

[0035] Furthermore, the plurality of protrusions 110 include a plurality of first protrusions 1101 and a plurality of second protrusions 1102 spaced apart on both sides of the receiving slot 111, wherein the first protrusions 1101 and the second protrusions 1102 are both triangular in shape, and the tops of the first protrusions 1101 and the second protrusions 1102 are both arc-shaped. It should be understood that the arc-shaped tops of the first protrusions 1101 and the second protrusions 1102 make it more comfortable to contact with the skin.

[0036] Of course, in some embodiments, the first protrusion 1101 and the plurality of second protrusions 1102 are both toothed.

[0037] Preferably, the first protrusion 1101 and the second protrusion 1102 are symmetrically arranged, or the first protrusion 1101 and the second protrusion 1102 are asymmetrically arranged and staggered.

[0038] Of course, in other embodiments, the needle body 12 is fixedly disposed at the end of the branch rod 11 away from the handle rod 10, that is, the locking part 121 is fixedly disposed in the receiving slot 111. Specifically, the outer wall of the end of the branch rod 11 away from the handle rod 10 is provided with a first positioning hole 1111 and a second positioning hole 1112 that communicate with the receiving slot 111 at intervals. The locking part 121 is provided with a first locking hole 1211 corresponding to the first positioning hole 1111 and a second locking hole 1212 corresponding to the second positioning hole 1112. A first insert rod is inserted into the first positioning hole 1111 and the first locking hole 1211, and a second insert rod is inserted into the second positioning hole 1112 and the second locking hole 1212.

[0039] Of course, in other embodiments, the end of the locking part 121 away from the needle part 122 is provided with a first magnet, and the receiving slot 111 is provided with a second magnet that attracts the first magnet, so that the locking part 121 is set in the receiving slot 111 by magnetic attraction.
