Backflow prevention disposable ampoule bottle for injection

Abstract

The invention provides a backflow prevention disposable ampoule bottle for injection. The backflow prevention disposable ampoule bottle comprises an ampoule bottle body, wherein the ampoule bottle body is provided with a neck part and a bottom push sheet, and is of a compressible air bellow structure; the bottom push sheet is used for pushing the ampoule bottle body. The backflow prevention disposable ampoule bottle is characterized by further comprising a clamping slot; the clamping slot consists of two or more clamping claws uniformly distributed around the ampoule bottle body; the clamping claws are inversely L-shaped, with one-edges combined at the neck part; the other edges of the inversely L-shaped clamping claws are adjacent to the ampoule bottle body and extend to the bottom close to the ampoule bottle body along the ampoule bottle body; the distance between the other edges of the clamping claws is equal to or slightly greater than the diameter of the bottom push sheet; clamping hooks are oppositely arranged at the tail ends of the other edges. According to the ampoule bottle provided by the invention, the operation steps during use are reduced, pollution to medicinal liquor is avoided, and misuse of medicines is reduced.

Description

technical field [0001] The invention relates to an ampoule bottle, in particular to an anti-reflux disposable injection ampoule bottle. Background technique [0002] Ampoules are commonly used to store injections such as drugs for injection, vaccines, and high-purity chemicals. Although the ampoule bottle has advantages such as low cost, safe storage, and convenient transportation, in actual use, the liquid medicine in the bottle needs to be broken off with a syringe because of the need to break the glass seal at the mouth of the ampoule bottle. The glass seal generally adopts special treatment to make the seal easy to break. However, the fragility of glass makes it possible for medical personnel to cut the broken glass when breaking the mouth of the ampoule by hand; Falling into the bottle, causing contamination of the liquid medicine; what's more, glass shards will be injected into the human body along with the liquid medicine, causing embolism. In addition, before the l...

Problems solved by technology

[0010] However, although the injection ampoule bottle with a bellows-type push-push injection structure solves the problem of drug liquid contamination caused by knocking open the ampoule bottle, another problem follows-the problem of backflow during injection and precise drug delivery

After removing the gas in the ampoule, when performing subcutaneous injection, it is very easy for the medical staff to re-inhale the gas due to the unstable hand of the medical staff, resulting in a safety accident

In addition, the existing one-time injection ampoules, the control of the liquid injection during injection is impossible to talk about, and it is not known how much liquid is injected
