Tumor patient effusion extracting and discharging device

Abstract

The invention discloses a tumor patient effusion extracting and discharging device. An infusion pump is arranged in the inner cavity of a box body, a liquid storage box is fixed to the bottom of the inner cavity of the box body, a flow limiter communicated with the liquid storage box is fixed to the right side of the top of the liquid storage box, and the left end of a liquid suction pipe penetrates through the right side wall of the box body and then is connected with the input end of the infusion pump; the bottom of the right side wall of the box body is fixedly connected with a liquid discharging pipe, and the left end of the liquid discharging pipe penetrates through the box body and the liquid storage box and then extends into the inner cavity of the liquid storage box. According to the tumor patient effusion extracting and discharging device, an air guide pipe is fixedly connected to the left side of the liquid storage box, and an air purifier is arranged on the left side of the air guide pipe, so that foul gas in accumulated liquid can be effectively filtered and absorbed; through the arrangement of the flow limiter, self-adaptive control over the flow rate and the flow velocity of the extracted accumulated liquid can be conducted, meanwhile, when the flow rate is large, automatic closing of a drainage channel can be achieved, and the accumulated liquid have good uniformity during extraction and circulation; and through an arranged adjusting screw rod and a guide rod, the length of the part, entering a body, of a pipette can be finely adjusted.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a device for extracting and discharging effusion of tumor patients. Background technique [0002] In the clinical treatment of tumor patients, pleural or peritoneal effusions are often encountered, which requires drainage of intracavitary effusions. The early method of effusion drainage is to use large-scale syringes to connect puncture needles with rubber tubes for extraction. , but the drainage efficiency of this extraction method is low. In the prior art, there is also a special effusion discharge device, which uses a micropump to replace the mechanical extraction method, but although this method has a fast extraction rate, it has the following problems: [0003] (1) Since the depth of the needle entering the body cannot be precisely adjusted, it is not suitable for the discharge of a small amount of residual fluid in the later stage; [0004] (2) Since the flow ...

AI Technical Summary

Problems solved by technology

[0003] (1) Since the depth of the needle entering the body cannot be accurately adjusted, it is not suitable for the discharge of a small amount of residual fluid in the later stage;

[0004] (2) Since the flow rate of the absorbed effusion cannot be effectively controlled during mechanical extraction, its long-term use will cause discomfort to the patient;

[0005] (3) If the extracted effusion cannot be effectively treated, the odor of the effusion will spread, which may affect the health of the staff. There are certain hidden dangers, and other cross-infection situations may also occur
