Embodiment 1
[0078] Such as figure 1 As shown, the air pressure regulating mechanism 10 for detecting body cavity pressure includes: a shell body 11 , an air pressure regulating member 12 and a first valve body 13 . The top of the shell body 11 has an opening, and the bottom is provided with a first air vent a; at least a part of the air pressure regulator 12 is located in the shell body 11, and one end protrudes from the opening as a free end b, which is used to adjust the access to and from the first vent. The amount of gas in the air vent a; wherein, the gas pressure regulator 12 and the shell body 11 are airtight; the first valve body 13 has a gas passage c arranged through; one end of the gas passage c is The second vent d is in communication with the first vent a; the other end of the gas passage c is a free end that can be sealed, and is used to connect to the test host, and when detecting body cavity pressure, it can conduct the The second vent d is connected to the test host. Th...
Embodiment 2
[0093] Embodiments of the present disclosure also provide a detection catheter, such as figure 2 As shown, the detection catheter 1 includes: at least one air pressure adjustment mechanism 10 and at least one sub-channel pipeline 20, the number of sub-channel pipelines 20 is adapted to the number of air pressure adjustment mechanisms 10, and each sub-channel pipeline 20 is compatible with an air pressure adjustment mechanism The first vent a of 10 communicates. The air pressure regulating mechanism 10 is any structure in the first embodiment. The number of the air pressure regulating mechanism 10 of the present disclosure can be two, three, four or more, and of course, only one can be included. Those of ordinary skill in the art should understand that the air pressure can be reasonably designed according to the needs of practical applications. The number of adjustment mechanisms is not particularly limited in the present disclosure.
[0094] According to an embodiment of th...
Embodiment 3
[0106] The embodiment of the present disclosure also provides a detection catheter, which is different from embodiment 2 in that the air pressure adjustment mechanism and the multi-channel pipeline are integrated in one body, so that the air pressure adjustment mechanism is also used as a consumable and cannot be reused. In the embodiment of the present disclosure, by using the sealed chamber, the multi-channel pipeline, and the seal as the main consumables, the air pressure adjustment mechanism can be reused, reducing medical waste, reducing costs, and reducing the financial burden on patients.
[0107] Such as image 3 As shown, the detection catheter 2 includes: at least one air pressure adjustment mechanism 10, at least one sub-channel pipeline, a sealed chamber 40 and at least one sealing member 50; the sealed chamber 40 and the sealing member 50 form a closed space for containing Set the sub-channel piping. Each sub-channel pipeline communicates with the first vent a of...
