Technical Field

The utility model relates to a continuous liquid-accumulating extractor, belonging to the technical field of liquid-extracting tools.

Background

Tumor patients with pleural effusion or peritoneal effusion need to frequently perform puncture and liquid extraction, in order to relieve the pain of the patients, puncture needles are embedded in the thoracic cavity or abdominal cavity of the patients under most conditions, so that the patients can repeatedly extract liquid for use in the later period, even after the puncture needles are embedded, medical workers also need to adopt a traditional syringe to extract liquid, the efficiency is low, and the labor is very great; most liquid pumping devices in the market can only realize the functions of diversion and collection of accumulated liquid, and cannot pump liquid; the hydrops extractor of local drawing liquid function, manual requirement medical personnel repeatedly operate, and automatic price is too high again, and a lot of hospitals and patients do not wish to purchase the use.

SUMMERY OF THE UTILITY MODEL

In order to solve the defects of the prior art, the utility model provides the accumulated liquid continuous extractor which can directly extract liquid when being used for the first time, realizes automatic continuous liquid extraction by utilizing negative pressure, has adjustable liquid extraction speed and flow guide speed, simple structure and low manufacturing cost, can be detached for cleaning and can be repeatedly used, thereby reducing the labor intensity of medical personnel and improving the liquid extraction efficiency.

The technical scheme adopted by the utility model for solving the technical problems is as follows: a continuous liquid-accumulating extractor is composed of a rectangular box with a hook fixed to its top, a liquid sucking tube inserted in the top of rectangular box, a liquid discharging tube inserted in the bottom of rectangular box, a pressure sucking tube inserted in the top of rectangular box and connected to its inner wall, a ball valve cavity in the middle of liquid sucking tube, a ball valve in said ball valve cavity, a sealing rubber plug fixed to two stop rings on the inner wall of pressure sucking tube, after the ball valve is closed, the rectangular box is sealed by the sealing rubber plug, and the rectangular box is vacuumized or filled with filling liquid.

Furthermore, the end parts of the liquid suction pipe and the liquid discharge pipe are of a pipe connector type, the rectangular box, the liquid suction pipe, the pressure suction pipe and the liquid discharge pipe are integrally formed by injection molding of transparent materials, the ball valve is an injection molding part, and a sealing gasket is arranged in the sealing cover of the ball valve.

Connecting the liquid pumping pipe with a puncture needle pre-embedded in the thoracic cavity or abdominal cavity of a patient through a catheter, and connecting the liquid discharge pipe with a collection belt or a collection cylinder through a catheter; when a vacuum cavity is formed in the rectangular box, firstly opening a ball valve on a liquid pumping pipe to facilitate vacuum liquid pumping, pumping accumulated liquid into the rectangular box, controlling the liquid pumping speed by swinging the angle of the ball valve in the pumping process, opening the ball valve on the liquid discharging pipe when the accumulated liquid in the rectangular box is about to be filled, discharging the accumulated liquid in the rectangular box from the liquid discharging pipe, wherein in the discharging process, as the box body is a long rectangular body, the negative pressure above the accumulated liquid in the box is gradually increased, and when the negative pressure value reaches the pressure required by liquid pumping, the pleural and abdominal dropsy are continuously pumped into the rectangular box, so that continuous liquid pumping is realized; when filling liquid is filled in the rectangular box, the ball valves of the liquid pumping pipe and the liquid discharge pipe are opened simultaneously, the filling liquid in the rectangular box is discharged gradually, the stroke above the liquid level in the box is negative, liquid pumping is realized, and after accumulated liquid enters the rectangular box, the liquid discharge pipe continues to discharge liquid, so that continuous liquid pumping is realized.
