Abstract

The invention relates to a leak-proof applicator to solve the technical problem that fluid leakage often occurs after thoracoabdominal puncture or puncture and tube placement of the applicator in the prior art. The leak-proof applicator of the present invention covers the wound surface of the absorbent layer on the wound surface during use, and the protruding part with grooves on the overhanging end is covered on the periphery of the tube hole, which can achieve a better fixing effect. It can also absorb the effusion and effectively prevent the effusion from leaking out. In the case of a large amount of effusion, the effusion can also be absorbed by the absorbing layer through the communication hole, thereby increasing the liquid absorption effect of the application of the present invention. The protrusions can also be well positioned around the cannula hole without falling off when the patient moves, in which case the wound dressing in the groove can remain in contact with the cannula hole for continuous effect to promote cannula healing. Therefore, the present invention can avoid the outflow of effusion, prevent the application and the dressing from falling off, and reduce the pain of the patient and the risk of infection.

Description

Leak protection is applied ointment or plaster

Technical Field

The invention relates to a leak-proof application.

Background

Many patients, particularly those with advanced solid tumors and tuberculous pleurisy, are most often associated with pleural and peritoneal effusions, in which case most patients undergo thoracoabdominal paracentesis, or puncture catheterization. After the patient punctures or extracts the tube (especially under the condition that the drainage tube is left on the body for 10-15 days after the tube is punctured), a tube hole can be formed after the tube is extracted, and most of the influences of basic diseases such as diabetes and the like are removed, and the healing can be gradually carried out after 24-72 hours. The phenomenon of effusion leakage can appear in the tube hole after the operation or after the drainage tube is pulled out. The conventional application is usually fixed in the following way: and a plurality of adhesive tapes are added for pressurization and fixation after covering and applying, and the dressing is added for pressurization and bandaging and then is fixed by a chest belt or an abdominal belt. The fixed form is poor in patient perception, and the hot summer season also increases patient discomfort and does not prevent effusion from leaking out. In clinical application, the effect of only using the traditional application or dressing is poor, and effusion leakage cannot be avoided. The leakage of the accumulated liquid not only brings inconvenience to the patient, but also easily causes infection and increases the pain of the patient.
