Plug-in type dual-valve cover

Abstract

The invention discloses a plug-in type dual-valve cover, wherein a dual-valve cover body is provided with a chemicals mixing channel and a transfusion channel; the chemicals mixing channel extends out of the dual-valve cover body to form a chemicals mixing port; an annular lug boss is saliently arranged on the external wall of the chemicals mixing port and provided with an external thread; a clamp ring is arranged on the external wall of an end port of the chemicals mixing port, and a diaphragm is arranged inside the chemicals mixing port; and the external diameter of the clamp ring is not more than the external diameter of the annular lug boss. When the plug-in type dual-valve cover is in use, the dual-valve cover body is welded on a port of a transfusion container, the bottom of a syringe is sleeved on the chemicals mixing port, the clamp ring is located on a locating ring and the syringe and the chemicals mixing port are fixed; during the mixing of the chemicals, a chemicals container is inserted into a chemicals mixing nozzle and rotated downward, so that the diaphragm is punctured by the bottom of a chemicals feeding syringe and the chemicals container is communicated with the inside of the transfusion container; a hose for connection and an easily folded handle are not needed during the use of the cover, so that not only the mounting location for the hose is reduced, butalso the liquid leakage of a welded seam, caused by the welding defect of the hose, is avoided; meanwhile, the plug-in type dual-valve cover is molded at a time and has wider scope of application.

Description

technical field [0001] The invention relates to a medical device, in particular to a double valve cover connected with an infusion container. Background technique [0002] In 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 container, and the injection or output of the drug solution in the infusion container is often realized through a double valve cover. [0003] In the prior art, the double valve cover includes a double valve cover body, a drug mixing channel and an infusion channel are arranged on the top of the double valve cover body, and the bottom of the double valve cover body is a connection port. The drug mixing channel extends out of the double valve cover body to form a cylindrical hollow drug mixing interface, and the infusion channel extends out of the double valve cover body to form a cylindrical hollow structure infusion inte...

AI Technical Summary

Problems solved by technology

[0004] The double valve cover of the above structure mainly has the following disadvantages in use: 1. When connecting with the drug mixing nozzle, it needs to be connected through a hose, and one end of the hose is sleeved on the drug mixing interface and welded to the drug mixing interface. The other end of the hose is set on the syringe body on the mixing nozzle, 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 welding position due to the welding position in the mixing nozzle. The probability of liquid leakage during medicine; 2. The double valve cover is connected to the mixing nozzle through a hose. Due to the limitation of the material used in the hose, at low temperature (such as sub-zero temperature), it is easy to cause the welding part of the hose to crack, and then 3. When the double valve cover of the above structure is connected to the mixing nozzle through a hose, a frangible handle needs to be installed in the hose
