Description

Technical Field

[0001] The utility model relates to the technical field of pricking needles, in particular to an automatic rebound needle which can be used for pricking treatment of painful parts with medicine without professional skills. Background Art

[0002] In vivo testing for allergens in human skin primarily involves understanding the body's allergic status to allergens through skin testing. Numerous skin testing methods exist, with allergen skin prick tests and intradermal tests being the most commonly used. Compared to intradermal allergen tests, allergen prick tests are simpler and faster to perform, cause less damage to the skin, are less painful, have a lower incidence of nonspecific skin reactions, and offer highly reproducible results. Therefore, in clinical research and practice both domestically and internationally, allergen skin prick tests are increasingly replacing traditional intradermal tests. Existing prick needles are standalone needles and cannot be used with medication. Summary of the Invention

[0012] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0013] like Figure 1 As shown, the medicated puncture needle includes a needle sleeve, the upper end of which is screwed with an upper end screw resistor; the sliding sleeve is placed inside the needle sleeve, and a "7"-shaped sliding groove is provided on the sliding sleeve. The oblique button is installed in the needle sleeve, and the upper end of the oblique button extends outward from the upper end of the needle sleeve. The inner spring sleeve is placed on the part of the oblique button located inside the needle sleeve, and a return fixing column is provided at the lower end of the inner spring. The piston pin on the return fixing column is clamped in the upper part of the "7"-shaped sliding groove on the sliding sleeve; an outer spring is placed on the outer end of the needle sleeve; the outer spring is connected to the convex pressure ring on the outer side of the oblique button;

[0014] The moving piston rod is installed in the needle sleeve and is located at the lower end of the needle sleeve; the front end of the moving piston rod is a conical structure, the middle section is a thin neck, and the tail end is provided with a dovetail mouth; the needle clamp spring is sleeved on the thin neck in the middle of the moving piston rod; the special disposable medicated needle is installed in the needle sleeve and fixed by the lower end needle resistance; the special disposable medicated needle is clamped on the moving piston rod through the dovetail mouth; the lower end needle resistance is provided with an adjusting thread, and the adjusting bolt is installed on the lower end needle group through the adjusting thread; the lower end needle resistance is a hollow structure, and a sliding groove is provided on the side of the lower end needle sleeve.

[0015] Working principle:

[0016] This product consists of: the main body is a needle sleeve 13, the upper part of which is topped with an upper end screw resistance 1, an inner spring 3 and an outer spring 14. The outer spring 14 is pressed by the oblique button 15 to work, and the inner spring 3 returns to its original position, so that it can be used reciprocatingly. The return fixing column 16 under the spring clamps the piston pin 4 and is stuck in the upper part of the "7"-shaped slide groove of the sliding sleeve 5. When the oblique button 15 is pressed, the piston rod 6 is the lower working column, and the needle clamp spring 7 is sleeved in the middle of the moving piston rod 6. At the thin neck, when the work is completed, the upper part returns to its position to store energy for the next firing, ready to be fired; the disposable needle 8 and the medicine feed tube 10 are sequentially installed into the needle sleeve 13 from the lower end, and are fixed by the lower needle resistance 12. The lower needle resistance 12 has an adjusting thread, and the lower needle resistance 12 is a hollow structure for adjusting the depth of needle insertion; the lower needle sleeve 9 is a hollow structure, and there is a sliding groove on the side to facilitate the sliding and pricking of the needle therein, and the lower end of the moving piston rod 6 is provided with a dovetail mouth for fixing the medicine-carrying needle.
