Description

Technical Field

[0001] The utility model relates to the technical field of enema machine filling mechanisms, in particular to a medicine filling mechanism for an enema machine. Background Art

[0002] The enema machine is a medical device used for intestinal cleansing, defecation, capsules, etc. When in use, the enema machine needs to inject the medicine into the patient's body through the perfusion mechanism to achieve the cleaning effect.

[0003] According to the description of a drug liquid perfusion device for an enema machine disclosed on the patent website (authorization announcement number: CN 218961453U), "The utility model provides a drug liquid perfusion device for an enema machine, which relates to the technical field of perfusion devices, including: a first connecting tube and an auxiliary part; the first connecting tube is connected to the enema machine, and an injection head is connected to the first connecting tube; the auxiliary part is composed of an air bag and a second connecting tube, and the air bag is installed on the injection head. Because a round ball is placed in the injection head, the round ball is in a sealed state at the air inlet nozzle of the injection head at this time. During use, the round ball can prevent the liquid in the patient's body from flowing back, and then the refluxed liquid enters the enema machine through the first connecting tube, causing contamination of the enema machine, which solves the problem that the injection head needs to be inserted into the patient's body during enema. At this time, the liquid in the patient's anus and rectum is easy to flow back, and the refluxed liquid is easy to cause contamination to the enema machine. During enema, the drug liquid or the liquid in the patient's body will flow out along the injection head position, causing contamination."
