Fixed plaster for puncture needle hole

Abstract

The invention provides a fixed plaster for a puncture needle hole. The fixed plaster comprises medical proof fabric, a waterproof silicone base and a replaceable inner core. The medical proof fabric comprises a first surface with a gel layer and an opposite second surface, and a crack is formed in the middle of the medical proof fabric. The waterproof silicone base is arranged on the first surface of the medical proof fabric, the waterproof silicone base is provided with an annular bottom which is fixed to the first surface and an annular wall portion which is arranged above the annular bottom, and a first containing space is defined by the annular wall portion and the annular bottom. The replaceable inner core is arranged in the first containing space in an insertion and extraction mode, the replaceable inner core comprises a silicone cover, a hand pulling portion and an absorption portion, the absorption portion is arranged in a groove of the silicone cover, the hand pulling portion is fixed to the cover head of the silicone cover and corresponds to the crack of the medical proof fabric, and the hand pulling portion is located on a second surface which extends from the crack to the medical proof fabric when the silicone cover is located in the first containing space. According to the fixed plaster for the puncture needle hole, ascites exosmosis can be effectively avoided, the wound is also disinfected conveniently, and the water absorption portion is further replaced conveniently.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a puncture needle hole fixed applicator. Background technique [0002] At present, paracentesis is a commonly used clinical diagnosis and treatment technique. Most of the operation adopts the "Z" shape needle insertion method. After the puncture, the puncture point is often covered with gauze, and then pressed with a rubber bottle cap, and tied around the abdomen to the waist to fix it to prevent postoperative ascites from leaking out. For a small amount of ascites The patient can play a role of local packing, but for patients with advanced liver cirrhosis ascites and advanced abdominal malignant tumors with a large amount of ascites, because the intra-abdominal pressure is too high and the fat layer of the abdominal wall becomes thinner, this method of puncture and needle insertion cannot prevent postoperative ascites Leakage from the puncture point, and the gauze covering the pu...

Problems solved by technology

Most of the operation adopts the "Z" shape needle insertion method. After the puncture, the puncture point is often covered with gauze, and then pressed with a rubber medicine bottle cap, and fixed with a band around the abdomen to the waist to prevent postoperative ascites from leaking out. For a small amount of ascites The patient can play a role of local packing, but for patients with advanced liver cirrhosis ascites and advanced abdominal malignant tumors with a large amount of ascites, because the intra-abdominal pressure is too high and the fat layer of the abdominal wall becomes thinner, this method of puncture and needle insertion cannot prevent postoperative ascites Leakage from the puncture point, and the gauze covering the puncture site is often larger than the rubber bottle cap. Clinically, it is often seen that the gauze and even the cover on the patient’s body are wetted by the extravasated ascites. Intraperitoneal contamination also increases the psychological burden of patients
