Infusion bag tube opening

Abstract

The invention discloses an infusion bag tube opening, which comprises a main tube and a puncture tube, wherein one end of the main tube is provided with a sealing film; the puncture tube comprises a sharp thorn-shaped tube head and a tube body; the sharp thorn-shaped tube head of the puncture tube faces the sealing film, and is embedded in a main tube cavity; the tail part of the tube body is exposed out of a main tube; by jacking and pushing the tube body, the sharp thorn-shaped tube head pierces the sealing film to realize the communication of an infusion bag with the outside. The infusion bag tube opening has the advantages that before the infusion bag tube opening is used, the infusion bag and powdery medicine are respectively in a sealed state and are mutually separated; the phenomenon of reaction taking due to advanced mixing of two medicine cannot occur; the medicine quality stability is ensured; the production process is simple; the production cost is low; the economic burden of a patient is reduced; the powdery medicine uses market sold powdery medicine packed by ordinary penicillin bottles; the medicine stability reduction due to plastic package materials of ordinary double-chamber bag package is avoided; the clinic use is convenient.

Description

technical field [0001] The invention relates to the field of medicine packaging, in particular to a spout of an infusion bag. Background technique [0002] In order to solve the problem of storage of unstable drugs in the solution state, the ready-to-mix powder-liquid double-chamber infusion bag product in the prior art is divided into two independent chambers by two openable weakly welded partition bars, which are respectively filled with injection solvents and Drug powder, before clinical use, the medical staff only need to apply a certain pressure to the liquid chamber, open the weak welding partition between the two chambers to make the two chambers communicate with each other and shake well, then the injection solvent and drug powder can be mixed. It is fully mixed for clinical use. Compared with the current traditional single-chamber infusion bag, it has the advantages of short dispensing time, low pollution rate, quick and convenient operation, and is especially suita...

Problems solved by technology

[0003] However, in order to ensure the effective opening of the weak welds before use in the existing double-chamber infusion bags, the welding strength is difficult to guarantee, and pressure is easily generated in the bag during transportation and storage, so that the weak welds of the above-mentioned double-chamber bags are removed in advance. If the drug is opened, the stability of the drug cannot be guaranteed. In addition, this type of double-chamber bag needs to be divided into two kinds of drugs with different properties, liquid and powder, in the same bag. The production process is too complicated and the production cost is too high. Patients bring additional economic burden, and plastic packaging cannot be applied to some unstable drugs due to certain physical and chemical properties
