Non-slipping thoracoabdominal cavity indwelling drainage apparatus

Abstract

The invention discloses a non-slipping thoracoabdominal cavity indwelling drainage apparatus, which comprises an indwelling catheter, an inflating cuff, a clamping kettle, a drainage tube, a drainage bag and a liquid check valve, wherein the inflating cuff is arranged at the outer side of the indwelling catheter and communicates with the clamping kettle by virtue of a gas guide tube; a gas injection device is connected to the exterior of the clamping kettle; a conical drainage head is arranged at the front end of the indwelling catheter; drainage holes are formed in the front side of the indwelling catheter; a truncated cone-shaped structure of an inner groove is arranged at the tail end of the indwelling catheter; a drainage tube connector is arranged at the front end of the drainage tube; a drainage bag connector is in matched connection to the truncated cone-shaped structure of the inner groove; the tail end of the drainage tube communicates with the drainage bag; and a flow rate controller and the liquid check valve are arranged on the drainage tube. According to the device, the indwelling catheter can be prevented from getting fallen off by virtue of the inflating cuff, and seepage of effusion from a puncture site can be prevented; by virtue of the plurality of drainage holes which are designed in the front end of the indwelling catheter, drainage is facilitated and blockage is prevented; the drainage tube makes use of a standard interface, so that a glass connector or empty needle transformation is prevented; by virtue of the flow rate controller, individual drainage can be implemented on a patient; and by designing the liquid check valve, backflow of drainage liquid can be prevented.

Description

technical field [0001] The invention belongs to the technical field of medical instruments and devices, and in particular relates to a drainage device for pleural and peritoneal fluid that prevents slippage. Background technique [0002] Closed drainage of the thoracoabdominal cavity is a widely used technique in surgery, medical oncology, and intensive care medicine, and is an effective method for treating pleural and peritoneal effusions. Common causes of pleural and peritoneal effusions are inflammation, malignant tumors, etc. Due to the long course of treatment for the etiology and the rapid formation of effusion, when more than a moderate amount of effusion occurs, multiple pumping is often required. As the incidence of tumors increases year by year, the incidence of malignant tumors combined with malignant pleural effusions also increases significantly. During the treatment of malignant pleural effusion, long-term indwelling drainage tubes are often required. On the o...
