Detailed Description

In order to make the objects, technical solutions and advantages of the present invention easier to clearly understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

As shown in fig. 1, the abdominal puncture drainage device comprises a drainage main pipe 2 and a puncture needle 1 arranged inside the drainage main pipe 2, wherein the drainage main pipe 2 is of a hollow structure, the inner diameter of the drainage main pipe 2 is slightly larger than the diameter of the puncture needle 1, the diameter of the puncture needle 1 is 18-23G, the damage to tissues is small when the diameter is thin, the puncture needle 1 can clearly develop under ultrasound, and medical staff can puncture a focus under direct vision of ultrasound;

the main drainage pipe 2 is sequentially provided with an injection branch pipe 4, a flowmeter 7, a speed regulating switch 8 and a branch drainage pipe 5, the branch drainage pipe 5 is connected with a drainage bag 9 through a one-way valve 6, the flow direction of the one-way valve 6 on the branch drainage pipe 5 is from the main drainage pipe 2 to the branch drainage pipe 5, so that secondary infection caused by backflow can be prevented, the drainage bag 9 is connected with a negative pressure ball 11 through an air pipe 10, the negative pressure ball 11 is provided with an exhaust valve 1101, and the negative pressure ball 11 can accelerate the outflow of ascites; the flowmeter 7 is of a model DK800, can be used for observing the flow rate of ascites to control the speed regulating switch 8, and prevents the patient from discomfort caused by too high flow rate or too low flow rate and too much time consumption;

the injection branch pipe 4 is connected with an injector through a one-way valve 6, the flow direction of the one-way valve 6 on the injection branch pipe 4 is from the injection branch pipe 4 to the drainage main pipe 2, so that medicine injection can be facilitated, and the one-way valve 6 adopts a common medical one-way valve;
