Patent number: 11260166Abstract: Disclosed are various embodiments for an anti-reflux tube-type enemator that is leakproof, easy-to-clean, and quickly inflates to provide a steady flow of solution. The anti-reflux enemator includes a nozzle comprising a nozzle outlet, a tube fluidly coupled to the nozzle, and an enema bulb fluidly coupled to the tube. The enema bulb is configured to store solution therein and, in response to a squeezing force applied to the enema bulb, direct the solution through the tube and the nozzle, and expel the solution through the nozzle outlet. An anti-reflux coupler is positioned between the enema bulb and the tube through which the solution passes from the enema bulb to the tube. One or more one-way air valves are positioned relative to an aperture of the enema bulb.Type: GrantFiled: September 27, 2019Date of Patent: March 1, 2022Assignee: NINGBO ALBERT NOVOSINO CO., LTDInventors: Yonggui Zhang, Haibo Hu
