Description

Extension shower nozzle and have duplex mixer of this extension shower nozzle

Technical Field

The utility model relates to the technical field of medical instruments, in particular to an extension nozzle and a duplex medicine mixer with the same.

Background

With the continuous development of treatment means in the medical industry, the clinical requirement of mixing two-component liquids is increasing day by day. For example, fibrin glue for solving the bleeding of a wound surface consists of fibrin and thrombin double components and is a double-component sealant for tissue sealing to prevent liquid leakage or air leakage.

The existing duplex medicine mixer usually realizes liquid mixing in a spray head after a solution in an injector flows through a tee joint, and the tee joint is fixed on a duplex injector frame by adopting a strip-shaped buckle, such as a pig fibrin adhesive administration device (application number: 201420427435.X) in the Chinese invention patent and a binary liquid mixing device (application number: 201821009248.4) in the Chinese invention patent. The fluid pressure is directly related to the pushing speed of the injector, and the fluid pressure also reacts to the push rod of the injector. When the pushing speed is high, the liquid pressure is high, the push rod resistance is high, the buckle is likely to slip and break, the tee joint is separated from the injection frame, the spraying fails, and the separated tee joint and the spray head even collide against the wound surface of the tissue to cause tissue damage.

The minimally invasive surgery is a surgery performed by using modern medical instruments such as a laparoscope, a thoracoscope and the like and related equipment, reduces the harm of the traditional surgery to the human body, and greatly reduces the inconvenience and pain of the patient caused by diseases. The minimally invasive surgery has the advantages of small wound, light pain and quick recovery. For deeper wounds in minimally invasive surgery, the existing drug delivery device is very difficult to operate, and fibrin glue or sealant products are difficult to spray to a target part, so that ideal treatment effect is difficult to obtain.
