Description

Ascites quantitative pumping device

technical field

The utility model belongs to the technical field of medical equipment, in particular to a quantitative pumping device for ascites.

Background technique

When extracting effusion from patients with abdominal effusion, the operation efficiency of using a syringe to extract ascites is very low. It is necessary to extract ascites from the patient one by one.

Utility model content

The problem to be solved by the utility model is to provide an ascites quantitative pumping device for automatically controlling the flow rate of the pumped ascites and controlling the pumping amount.

The specific technical scheme is as follows: a quantitative pumping device for ascites, characterized in that: it comprises an ascites storage bottle (5), the mouth of the ascites storage bottle (5) is provided with a sealing plug (2), and the sealing plug (2) A drainage tube (1) and a negative pressure tube (3) run through the inside, a flow sensor (1-1) and a one-way valve (1-2) are arranged in the middle of the drainage tube (1), and the negative pressure tube ( 3) A pressure relief valve (3-1) is provided in the middle part, the pressure relief valve (3-1) is an electric control valve, and the control end of the electric control valve is connected with the second output end of the controller;

The air outlet of described negative pressure pipe (3) links to each other with the air inlet of negative pressure aspirator (4);

A liquid level sensor is arranged inside the ascites storage bottle (5), the output end of the liquid level sensor is connected to the first input end of the controller, and the output end of the flow sensor (1-1) is connected to the first input end of the controller. The second input end of the controller is connected, and the adjustment end of the negative pressure suction device is connected with the first output end of the controller.

The principle of this technical solution: the controller controls the switch size of the negative pressure suction device through the flow sensor, and detects the water level in the ascites storage bottle through the liquid level sensor, thereby controlling the stop of the negative pressure suction device; The pressure in the ascites storage bottle is released, the sealing plug can be taken out, and the ascites in the ascites storage bottle is inspected or cleaned. When the water level in the ascites storage bottle reaches the set height, the controller stops the negative pressure suction device, opens the electric control valve, and automatically releases the pressure of the ascites storage bottle;

In order to better realize the utility model, it may be further that: the bottle body of the ascites storage bottle (5) is provided with a measuring scale (5-1);

The liquid level sensor is a buoy type liquid level sensor, or a float type liquid level sensor, or a hydrostatic liquid level sensor;

The flow sensor is close to the water inlet of the drainage tube (1), so that the ascites suction flow can be quickly detected.

The beneficial effects of the utility model are as follows: the utility model is designed with a controller, which has a high degree of automation, and the comfort and controllability of the utility model have been improved, and the operation is convenient; a sealing plug is set at the mouth of the ascites storage bottle, so This structure is convenient for cleaning the ascites storage bottle.
