Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an improved drainage device. Background Art

[0002] Ascites is a manifestation of many clinical diseases. Its common causes include cirrhosis, malignant tumors, peritonitis, etc. A large amount of ascites can cause severe chest tightness, dyspnea and other symptoms in patients, affecting their quality of life. Abdominal puncture and drainage is a common, effective and economical method for treating this symptom in clinical practice.

[0003] At present, the drainage tubes of existing drainage devices are all arranged at the top of the device, and there is a certain bend in the connection between the drainage tube and the device. During abdominal surgery, the exudate or pus at the surgical site may contain tissue fragments. Then, when the drainage tube is draining, the pus and tissue fragments are very likely to cause blockage at the bend of the drainage tube, resulting in the device being unable to drain. For this reason, we propose an improved drainage device. Utility Model Content

[0010] Preferably, the slide plate is slidably connected to the inner wall of the slide groove, and a hole cooperating with the slide rod is opened inside one side of the guide column.

[0011] The utility model provides an improved drainage device, which has the following beneficial effects:

[0012] 1. The improved drainage device cooperates with a negative pressure machine, a negative pressure tube, a mounting frame, a separation cylinder, a sealing cover, a mounting rod, a filter screen, a limiting ring, a drainage tube and a positioning groove. During drainage, the negative pressure machine creates negative pressure in the collection barrel, so that one end of the negative pressure tube generates suction. After the air inside the separation cylinder is discharged, the separation barrel can be negatively pressurized, so that the drainage tube can generate suction and can be used for drainage of effusion. During the drainage process, the effusion flows into the separation cylinder through the drainage tube and is filtered through the filter screen, thereby effectively preventing human tissue or pus in the effusion from clogging the bending part of the connection between the negative pressure tube and the barrel cover, thereby achieving separation of tissue fragments and effusion, and avoiding clogging of the drainage tube.

[0013] 2. The improved drainage device cooperates with the liquid inlet pipe, guide column, slide groove, slide rod, slide plate, spring and valve plate. When the negative pressure in the separation cylinder increases, the valve plate will be sucked open from one side of the liquid inlet pipe, so that the drainage tube will generate suction and suck the accumulated fluid into the separation cylinder. When the valve plate is opened, the displacement of the slide rod and the slide plate will squeeze the spring. In this way, when the negative pressure of the barrel cover stops, the valve plate will rebound through the spring to push the slide plate to drive the slide rod and the valve plate to reset. The liquid inlet pipe is blocked by the valve plate to prevent the accumulated fluid and tissue in the separation cylinder from flowing back into the drainage tube, thereby preventing the drained accumulated fluid from flowing back to the patient's drainage site to cause infection.
