Description

A new ascites drainage device

technical field

The utility model relates to the technical field of medical instruments, in particular to a novel ascites drainage device.

Background technique

When water accumulates in the abdominal cavity of the human body, it needs to be pumped out for treatment, which plays a very important role in the treatment of celiac disease. The current ascites puncture tools, such as steel needles, can only be used for one-time ascites drainage, and cannot be left in place for intermittent ascites drainage. Although there are some ascites puncture tools that can be left in place, the operation steps are complicated and need to be connected manually. Sex, and the operation process device is not in a closed state, there is a risk of body fluid contamination. Furthermore, the collected specimens are released from the drainage tube interface to the open test tubes for inspection. If a large amount of ascites is quantitatively analyzed, there is no standard container for collecting ascites at present.

Utility model content

The utility model aims to provide a novel ascites drainage device, which can visually and safely drain the fluid in the patient's abdominal cavity out of the human body.

In order to achieve the above object, the utility model is realized by adopting the following technical solutions: a novel ascites drainage device, including a puncture needle sleeve, a puncture needle, a transparent material tube, a drainage tube, a speed control controller, a drainage bag connector, a puncture pump Liquid tube, closed drainage bag, rubber plug, the outer wall of the puncture needle sleeve is provided with a water hole, the puncture needle sleeve is built with a puncture needle, the puncture needle sleeve is connected with the lower end of the transparent material tube, and the transparent The material pipe is connected with the side wall and the drainage tube, and the drainage tube is connected with the speed regulating controller and the closed drainage bag joint, and the closed drainage bag joint and the puncture suction tube are arranged on the closed drainage bag, and the puncture suction tube The liquid pipe is connected with the rubber stopper, and the transparent material pipe is provided with a T-shaped manual three-way ball valve and a piston, and the piston is above the T-shaped manual three-way ball valve.

Further, the puncture needle passes through the upper and lower passages of the T-shaped manual three-way ball valve and is connected with the piston.

Further, the left and right passages of the T-shaped manual three-way ball valve communicate with the drainage tube.

Further, there is a detachable sealing cover on the joint of the drainage bag.

Further, the puncture needle sleeve is made of colorless medical transparent soft material.

Further, the material of the T-type manual three-way ball valve is a colorless medical transparent material.

Further, the drainage tube, drainage bag connector, closed drainage bag, puncture suction tube and rubber

The plug is an existing product of the hospital.

The new ascites drainage device uses the principle of siphon to extract the fluid in the patient's abdominal cavity. The new ascites drainage device creates negative pressure in the new ascites drainage device through the movement of the piston, sucks the fluid out of the patient's abdominal cavity, and the fluid enters the T-shaped manual three Through the ball valve, turn the ball valve so that the effusion turns into the drainage tube and flows into the drainage bag at the lower place. Compared with the existing products, the new ascites drainage device can more effectively extract the effusion in the patient's abdominal cavity and can be left in the patient's body. The T-type hand-controlled three-way ball valve can control the flow direction of the effusion and the injected therapeutic liquid. Because the new ascites drainage device is in a sealed state, and there is no need to reserve various manifolds on the new ascites drainage device, it reduces the risk of the patient being exposed to the outside world. The risk of bacterial infection and the possibility of contamination of the device by the patient's body fluid also reduce the difficulty and cost of manufacturing the device. In addition, there is a screw thread on the interface of the closed drainage bag, which is connected with a matching detachable sealing cover, which is convenient for the device to be removed. The closed drainage bag is sent to the inspection department as a sample bag for inspection.
