Hard double interfaces with medicine mixing mouth and transfusion soft bag thereof

Abstract

The invention discloses hard double interfaces with a medicine mixing mouth. The hard double interfaces comprise a base, a medicine mixing clamping body, a syringe cylinder body and a medicine feeding syringe, wherein a medicine mixing interface extending out of the base is arranged on the base, and a clamping ring is arranged at the end port of the medicine mixing interface; the bottom of the medicine feeding syringe extends downwards to form a sealing plug installation cavity, and the inner wall of the syringe cylinder body is provided with a positioning ring; the syringe cylinder body is fixed on the medicine mixing interface through the positioning ring and the clamping ring; and when medicines are mixed, the medicine mixing mouth is rotated downwards, and the bottom of the syringe cylinder body penetrates through a diaphragm. The invention also discloses a transfusion soft bag. When the hard double interfaces are used, the syringe cylinder body is sleeved on the medicine mixing interface, thus the medicine mixing mouth is fixed on the medicine mixing interface; when the medicines are mixed, the medicine mixing mouth is rotated downwards, and the bottom of the medicine feedingsyringe penetrates through the diaphragm, thus a medicine container in the medicine mixing mouth is communicated with the inside of the transfusion soft bag; in the use process of the hard double interfaces and the transfusion soft bag, hose connectors and easily broken handles are not adopted, thus the hose installation working positions are reduced and the weld seam liquid leakage caused by welding defects of the hose is avoided; and the hard double interfaces and the transfusion soft bag thereof have broader application ranges.

Description

technical field [0001] The invention relates to a medical device, in particular to a hard double interface with a drug mixing nozzle and a soft transfusion bag thereof. Background technique [0002] In the clinical treatment of diseases, patients are often given infusions or drugs are directly injected into the body through intravenous infusion. The drugs are often stored in the infusion soft bag, and the drug solution in the infusion soft bag is often injected or output through a hard double with a mixing nozzle. interface implementation. [0003] In the prior art, the hard double interface with a drug mixing nozzle mainly includes a base, a drug mixing card body, a syringe body, a hose, a frangible handle and a drug dosing needle. The base has a drug mixing channel and an infusion channel, the drug mixing channel extends out of the base to form a cylindrical hollow drug mixing interface, and the infusion channel extends out of the base to form a cylindrical hollow infusio...

AI Technical Summary

Problems solved by technology

[0004] The hard double interface with the mixing nozzle of the above structure mainly has the following deficiencies in use: 1. When the syringe body is connected to the mixing interface, it needs to be connected through a hose, and one end of the hose is sleeved on the mixing interface, and is connected with the mixing interface. The mixed drug interface is welded, and the other end of the hose is set on the syringe body and welded with the syringe body, which not only increases the installation station of the hose, but also increases the welding position, which increases the number of parts due to welding. The probability of liquid leakage during drug mixing; 2. The drug mixing interface is connected to the drug mixing nozzle through a hose. Due to the limitation of the material used in the hose, at low temperatures (such as sub-zero temperatures), it is easy to cause the welded part of the hose to crack , which in turn leads to mixed drug leakage; 3. For the hard double interface with a mixed drug nozzle of the above structure, when the mixed drug interface is connected to the mixed drug nozzle through a hose, an easy-to-break handle needs to be installed in the hose
