Description

Technical Field

[0001] The utility model relates to the field of medical instruments, and more specifically to an anorectal and anal medicine pusher. Background Art

[0002] An anal medicine pusher refers to a syringe that can inject medicine into the patient's anus, and can effectively treat diseases in the patient's anus.

[0003] The current anorectal and anal medicine pusher, such as the "A Traditional Chinese Medicine Anorectal and Anal Medicine Pusher" proposed with patent number 202121362762.8, includes a syringe, a conical head is fixedly installed on one side of the syringe, a T-shaped slide groove is provided on the top of the syringe, and a T-shaped slider is slidably connected inside the T-shaped slide groove, an oil filling cylinder is fixedly installed on the top of the T-shaped slider, an annular groove is provided inside the conical head, a plurality of oil outlet holes are provided on the outside of the conical head, a second tube groove is provided inside the conical head and on one side of the annular groove, and a first tube groove is provided inside the syringe. The beneficial effect of the utility model is that the oil filling cylinder can be better installed and disassembled through the coordinated use of the T-shaped slider and the T-shaped slide groove. After the anal syringe is used, the oil filling cylinder can be removed and installed on a new syringe for continued use, so that the oil filling cylinder can be reused, which effectively avoids waste and saves costs.

[0004] The existing anorectal and anal medicine pushers are equipped with a detachable oiling cylinder, which can lubricate the medicine pushers when in use. However, in actual use, the oiling cylinder is disassembled and assembled to achieve the purpose of reuse, but the rest of the medicine pusher is disposable, and the injection head of the medicine pusher cannot be disassembled and replaced, and cannot be disinfected and reused, which increases the cost of use to a certain extent. Therefore, there is an urgent need to improve the technology of the anorectal and anal medicine pusher structure to improve this device. Utility Model Content
