A leak-proof applicator

Abstract

The invention relates to a leak-proof applicator to solve the technical problem that the applicator in the prior art often causes fluid leakage after thoracoabdominal puncture or puncture catheterization. When the anti-leak application of the present invention is used, the wound-facing surface of the absorbent layer is covered on the wound surface, and the protruding part with a groove on the overhanging end is set on the periphery of the tube hole, which can not only achieve a better fixing effect , can absorb effusion again, effectively prevent effusion from leaking out, and when the amount of effusion is large, the effusion can also be absorbed by the absorbent layer through the communicating holes, increasing the liquid absorption effect of the application of the present invention. When the patient moves, the protruding part can also be well covered on the periphery of the tube hole and will not fall off. In this case, the wound dressing in the groove can keep in contact with the tube hole and continue to take effect to promote the healing of the tube hole. Therefore, the present invention can prevent fluid outflow, application and dressing falling off, and reduce pain and infection risk of patients.

Description

technical field [0001] The invention relates to a leak-proof application. Background technique [0002] Most patients, especially those with advanced solid tumors and tuberculous pleurisy, will have pleural and peritoneal effusions. In this case, most patients undergo thoracoperitoneal puncture or puncture catheter drainage. After the patient is punctured or extubated (especially if the drainage tube has been left on the body for 10-15 days after the puncture and catheterization), a tube hole will be formed after the extubation, and most of the patients will not be affected by basic diseases such as diabetes. It takes 24-72 hours to heal gradually. After the operation or after the drainage tube is removed, fluid leakage will occur at the hole of the tube. The fixation method of the traditional application is usually: after covering the application, add multiple tapes to pressurize and fix, and then add a dressing to pressurize and wrap, and then fix it with a chest belt or...
