The invention provides an air-tightness inspection device for an insertion part, which is used for performing air-tightness inspection on the insertion part. According to the technical scheme, the air-tightness inspection device comprises a containing part, a connecting pipe, a check valve, a positive air pressure source and an air pressure monitoring part, wherein the check valve comprises an air inlet, a first air outlet and a second air outlet, and air enters from the air inlet in one way; the air inlet is connected with the positive air pressure source, the first air outlet is connected with the containing part by virtue of the connecting pipe, and the second air outlet is connected with the air pressure monitoring part; the containing part is used for containing the insertion part and sealing the contact position. By implementing the technical scheme of the air-tightness inspection device, the device structure can be simplified, the portability is enhanced, the use flow is simple and convenient, and the convenience is enhanced.
Description
technical field [0001] The invention relates to the technical field of intracavity interventional medicine, in particular to an insertion part air tightness inspection device. Background technique [0002] Intracavity ultrasound examination, endoscopy, etc. need to insert the insertion part into the body cavity. In terms of hygiene, the insertion part needs to be disinfected to prevent the cavity fluid of the previous patient from contaminating the next patient. In terms of safety, it is necessary to prevent insertion The internal circuit is harmful to the human body, so the insertion part is required to have high sealing performance. [0003] Currently, liquid-assisted testing is used for airtightness inspection of the insertion portion. See figure 1 , the device includes: a container 101 and a vacuum source 102 . The side wall of the container 101 has an air supply and exhaust pipe 1011 through which the vacuum source 102 communicates with the container 101 , and the to...
