Problems solved by technology

[0003] In the existing hepatic ascites suction operation, most of the syringes are connected to the puncture needle through the drainage tube, and the negative pressure suction is performed through the syringe, so as to suction the hepatic ascites. work intensity, and the single suction volume is low, and the suction efficiency is poor. Therefore, we propose a hepatic ascites suction device

Abstract

The invention discloses a liver ascites aspirator, which comprises a lower shell and an upper shell, the periphery of the bottom of the lower shell is connected with a base, the center of the bottom of the lower shell is connected with a first motor, the power output end of the top of the first motor is connected with a supporting shaft, and the end, extending into an inner cavity of the lower shell, of the supporting shaft is connected with a material collecting assembly; a second motor is connected to the right side wall of the upper shell; a worm is connected to the power output end of the second motor; a fixing ring is connected to the left side wall of an inner cavity of the upper shell; a piston cylinder is connected to the inner wall of the fixing ring; a piston plate is slidably connected into the piston cylinder in a sealed mode; a U-shaped rod is connected to the top of the piston plate; a transmission mechanism is connected to the bottom of the right end of the U-shaped rod; the left side of the bottom of the piston cylinder is connected with a joint tube; one end of the joint tube extending out of the upper shell is connected with a drainage hose; and the free end of the drainage hose is connected with a puncture needle. The liver ascites suction device is reasonable in structural design, the piston plate can move in the piston cylinder, the pressure intensity in the piston cylinder can be changed, and liver ascites suction and transfer are facilitated.

Description

technical field [0001] The invention relates to the technical field of medical related equipment, in particular to a hepatic ascites aspirator. Background technique [0002] In our normal body, there will be a small amount of ascites in the abdominal cavity. It is mainly used for lubricating effect. Once the ascites in the abdominal cavity is relatively large, it is easy to cause liver ascites. Hepatic ascites is a common complication of liver cirrhosis in the middle and late stages. The so-called hepatic ascites is ascites filling the liver. The presence of hepatic ascites can cause infection and other hazards to patients and pose a serious threat to health. Liver ascites is a serious disease in our life. This disease will directly endanger our health. The method of pumping hepatic ascites is to let the patient take the supine position, and need to take a puncture point in the left lower abdomen or right lower abdomen. [0003] In the existing hepatic ascites suction...
