Drainage device for hepatology nursing

Abstract

The invention discloses a drainage device for hepatology nursing. The drainage device comprises a liquid storage cavity, a drainage pump and a drainage end, the drainage end comprises a water collecting cavity, a sliding ring, a first cavity, a first rubber sleeve, a second cavity, a second rubber sleeve and a puncture cone. After the puncture cone is inserted into a liver and gallbladder, the sliding ring is connected with a sliding cylinder, the sliding cylinder is connected with an elastic sheet through a connecting rod, the sliding cylinder is moved, deformation of the elastic sheet is pushed by the connecting rod, so that the middles of the first rubber sleeve and the second rubber sleeve are synchronously expanded outwards, the device is bi-directionally limited by the expanded first rubber sleeve outside the liver and gallbladder and the expanded second rubber sleeve in the liver and gallbladder, falling of the device from a liver can be prevented, so that the device cannot be deeply inserted into the liver, sliding of the device at a liver inserting opening can be avoided by bi-directional limit of the first rubber sleeve and the second rubber sleeve, the device is firmly fixed, and patient pain caused by sliding of the device is avoided.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, in particular to a drainage device for hepatobiliary care. Background technique [0002] At present, many patients in general surgery need to carry drainage devices for a long time after surgery, such as drainage bags for bile drainage and pancreatic duct drainage bags for pancreatic juice drainage. The tube falls off. In the prior art, the application number 201520167547.0 discloses a special drainage device for hepatobiliary department, which includes a tube body and a drainage bag. A conical head is provided above the tube body, and a drainage device is provided between the conical head and the tube body. The elastic supporting column on the outer circumference of the upper part, through the control line connected with the elastic supporting part, makes the elastic supporting column bend and expand, so as to prevent the tube body from falling off from the liver and gallbladder, but i...

[0002] At present, many general surgery patients need to carry drainage devices for a long time after surgery, such as drainage bags for bile drainage and pancreatic duct drainage bags for pancreatic juice drainage. The tube falls off. In the prior art, the application number 201520167547.0 discloses a special drainage device for hepatobiliary department, which includes a tube body and a drainage bag. A conical head is provided above the tube body, and a drainage device is provided between the conical head and the tube body. The elastic supporting column on the outer circumference of the upper part, through the control line connected with the elastic supporting part, makes the elastic supporting column bend and expand, so as to prevent the tube body from falling off from the liver and gallbladder, but it cannot limit the sliding of the tube body in the liver and gallbladder. When the body is affected by external forces and slides into the liver and gallbladder, it is easy to increase the pain of the patient. In view of the shortcomings of the prior art, the present invention provides a drainage device for hepatobiliary care that can prevent the drainage tube from sliding
