Disposable central drug adding type infusion pump

Abstract

The invention discloses a disposable central drug adding type infusion pump which comprises a shell, an internal drug adding pipeline, an L-shaped two-way connecting pipe, a gland connecting pipe seat, a silicon capsule, a silicon capsule gland and a drum-shaped ring. The shell comprises an upper cover, a lower cover and an upper cover and lower cover fixing ring, and the upper cover and the lower cover are fixed together through the upper cover and lower cover fixing ring; one end of the internal drug adding pipeline is fixed to the gland connecting pipe seat, and the other end of the internal drug adding pipeline is communicated with the end, located in the shell, of the L-shaped two-way connecting pipe; the silicon capsule is arranged outside the drum-shaped ring in a sleeving mode, and the inner wall surface of the silicon capsule and the outer wall surface of the drum-shaped ring are attached together through clearance fitting; a through hole communicated with the silicon capsule is formed in the center of the drum-shaped ring. The disposable central drug adding type infusion pump has the advantages of being stable in output pressure, precise in output flow, less in residual drug liquid amount and the like.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a one-time-use central dosing type infusion pump. Background technique [0002] The infusion pump is a kind of disposable medical device that is pre-set by medical personnel according to the patient's pain condition and the appropriate drug dose is injected into the human body in a small amount to relieve or relieve the patient's pain. Traditional infusion pumps are generally non-central dosing infusion pumps, which have disadvantages such as unstable output pressure, inaccurate output flow, and large amount of drug residue. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art and provide a one-time use central dosing infusion pump, which has the advantages of stable output pressure, accurate output flow, and less residual liquid medicine. [0004] The technical solution to achieve the above purpose is:...
