Puncture device air impermeability detector

Abstract

The invention belongs to the field of medical equipment and in particular relates to a puncture device air impermeability detector comprising a main box body and a secondary box body. The main box body is provided with a processing device and an air supply device. An interactive interface and an adjusting button are disposed on the side of the main box body. The processing device includes a control module and a flow monitoring device. The control module is connected with the flow monitoring device, the air supply device and the interactive interface. The adjusting button is connected with theair supply device. A detection airbag is arranged inside the secondary box body. A detection port is disposed on the secondary box body. One end of the detection port is connected to the detection airbag. A pipe is connected between the main box body and the secondary box body. One end of the pipe is connected with the air supply device, and the other end of the pipe is connected with the detection airbag. The flow monitoring device is installed on the joint of the pipe and the air supply device, and is connected with the pipe. The puncture device air impermeability detector has scientific structure and convenient operation, can quickly output a detection result so as to achieve a visualized characteristic, The detection airbag is suitable for various types of puncture devices, reduces thepossibility of leakage, and achieves accurate detection results.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to an air tightness detector of a puncture device. Background technique [0002] A trocar is a medical device that is often used in abdominal surgery and other minimally invasive surgical operations, and is a widely used surgical instrument. The trocar can establish an access channel in the abdominal wall of the human body, so that other surgical instruments can enter the abdominal cavity and provide a channel for gas in and out. Since the trocar is mainly used in pneumoperitoneum surgery, there are high requirements on the air tightness of the trocar, and it is required that the product cannot or can only have a small amount of gas leakage during the operation. There are various detection methods for trocars, but most of them are inefficient. [0003] The Chinese invention patent with publication number CN 204903111 U discloses an air-tightness detection device for a puncture dev...

AI Technical Summary

Problems solved by technology

The piercer air tightness detection equipment can detect the air tightness of the piercer, but the equipment requires the operator to observe the rotameter all the time during the detection, and the result is not intuitive

At the same time, the cross-section of the test port is circular or polygonal, and needs to be replaced according to the specifications of the piercer to be tested. The replacement takes time and affects the detection efficiency.
