[0005] Furthermore, an annular upper cavity and an annular lower cavity are respectively provided at the upper and lower ends of the pressing cavity, a first annular flange matching the annular upper cavity is provided at the lower end of the bracket, and a second annular flange matching the annular lower cavity is provided at the upper end of the solution bottle, so that the bracket, the pressing cavity and the solution bottle form a detachable structure.

[0006] Furthermore, circular protrusions are provided on both sides of the bracket, and positioning holes matching the protrusions are provided on both sides of the cover, so that the cover will not shake or fall off when it is closed on the bracket.

[0007] The technical effects and advantages of the utility model: the utility model is provided with a pressing cavity between the bracket and the solution bottle, and medication is achieved by squeezing the pressing cavity. At the same time, the bracket, the pressing cavity and the solution bottle are designed to be detachable structures, which is convenient for replacing damaged parts.

DETAILED DESCRIPTION

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

[0013] The utility model provides Figure 1-3 The shown push-type roller needle applicator comprises a cover 1, a roller needle 2, a bracket 4, a push cavity 5 and a solution bottle 6. The push cavity 5 is elastic and is a cylindrical structure with two ends opened. The two ends of the push cavity 5 are respectively connected to the bracket 4 and the solution bottle 6. The cover 1 is covered on the bracket 4. Circular protrusions 42 are provided on both sides of the bracket 4. Positioning holes 11 matching the protrusions 42 are provided on both sides of the cover 1, so that the cover 1 will not shake or fall off when it is covered on the bracket 4. The bracket 4 is axially connected to a rotating shaft 3, which passes through the roller needle 2 and is fixed to the roller needle 2. A cylindrical hole 43 is provided at one end of the bracket 4 close to the roller needle 2. When the pressing cavity 5 is pressed, the medicine in the solution bottle 6 flows to the roller needle 2 through the cylindrical hole 43, thereby achieving drug administration.

[0014] In this embodiment, an annular upper cavity 51 and an annular lower cavity 52 are respectively provided at the upper and lower ends of the pressing cavity 5, a first annular flange 41 matching the annular upper cavity 51 is provided at the lower end of the bracket 4, and a second annular flange 61 matching the annular lower cavity 52 is provided at the upper end of the solution bottle 6, so that the bracket 4, the pressing cavity 5 and the solution bottle 6 form a detachable structure.

[0015] In this embodiment, the height of the cylindrical hole 43 is 1-3 mm, and the hole diameter is 0.6 mm.

[0016] It is worth noting that the diameters of the first annular flange 41 and the second annular flange 61 are respectively larger than the diameters of the annular upper cavity 51 and the annular lower cavity 52 , so that a sealing structure is formed after the card is clamped.

[0017] Working principle: When in use, fill the solution bottle 6 with liquid medicine, then snap the solution bottle 6 into the pressing cavity 5, snap the bracket 4 into the upper end of the pressing cavity 5, install the roller needle 2 onto the bracket 4, and administer the medicine by squeezing the pressing cavity 5. Control the squeezing force to control the amount of medicine administered.

[0018] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
