Problems solved by technology

[0004] At present, when detecting the patient's gastric pressure or esophageal pressure in the prior art, medical personnel need to connect the syringe to the interface of the detection catheter, inject gas into the balloon through the syringe to detect gastric pressure or esophageal pressure, and determine the injection pressure according to the scale of the syringe. However, the method of using the syringe scale to determine the volume of injected gas is often quantitatively inaccurate; in addition, after the syringe injects gas into the airbag, the detection catheter needs to be separated from it, and then connected to the external instrument, so that Only external instruments can collect the air pressure signal of the air bag to detect the patient's gastric pressure or esophageal pressure
In the face of a large number of detections, repeated separation-conduction operations increase the load on medical staff, resulting in a decrease in detection efficiency

Embodiment 1

[0078] as Figure 1 As shown, the barometric pressure regulating mechanism 10 for detecting the pressure of the body cavity comprises: the housing body 11, the air pressure regulator 12 and the first valve body 13. Shell body 11 has an opening at the top, and the bottom is provided with a first ventilation port a; Barometric pressure regulator 12 is located at least a portion within the shell body 11, one end protruding from the opening as the free end b, for adjusting the amount of gas in and out of the first vent a; Wherein, the air pressure regulator 12 and the shell 11 body is gas-sealed; The first valve body 13 has a gas channel c through the setting; One end of the gas channel c is a second vent d, and the first vent a is conducted; The other end of the gas channel c is a free end capable of sealing, for connecting the test host, and when detecting the body cavity pressure, it is possible to conduct the second vent d with the test host. The first valve body 13 may be disposed...

Embodiment 2

[0093] The present disclosure embodiment also provides a detection catheter, such as Figure 2 As shown, the detection catheter 1 comprises: at least one barometric pressure regulator 10 and at least one sub-channel line 20, the sub-channel line 20 and the number of pneumatic regulatory mechanism 10 are adapted, each sub-channel line 20 is connected with a first vent a pneumatic regulatory mechanism 10. The barometric pressure regulation mechanism 10 is any one of the structures in Example 1. The number of air pressure regulation mechanisms 10 of the present disclosure may be two, three, four or more, of course, may also comprise only one, those of ordinary skill in the art should understand, according to the needs of the actual application may be reasonably designed the number of air pressure regulation mechanisms, the present disclosure is not specifically limited herein.

[0094]According to an embodiment of the present disclosure, the number of sub-channel lines 20 may be two, ...

Embodiment 3

[0106] The present disclosure embodiment also provides a detection catheter, and Example 2 is different, in Example 2, the air pressure regulation mechanism, multi-channel pipeline integrated, so that the air pressure regulation mechanism is also used as a consumable and can not be reused. In the present embodiment, by using the sealed silo, multi-channel pipeline, seal as the main consumable, the air pressure adjustment mechanism can be reused, reducing medical waste, reducing costs, and reducing the economic burden of patients.

[0107] as Figure 3 As shown, the detection catheter 2 comprises: at least one barometric pressure regulation mechanism 10, at least one sub-channel line, sealing compartment 40 and at least one seal 50; The sealed compartment 40 forms a confined space with the seal 50 for accommodating the sub-channel piping. Each sub-channel line is connected with a first vent a of the barometric pressure regulation mechanism 10. Specifically, the first vent a is a hol...

Abstract

Embodiments of the present disclosure provide an air pressure adjustment mechanism, a detection catheter and a detection device for detecting body cavity pressure. The air pressure adjustment mechanism includes: a shell body with an opening at the top and a first air vent at the bottom; an air pressure adjustment member, at least a part of which is located in the shell body, and one end protrudes from the opening as a free end for adjusting the in and out The gas volume of the first air vent; wherein, the air-tightness between the air pressure regulator and the shell body; the first valve body has a gas passage arranged through; one end of the gas passage is the second The air vent communicates with the first air vent; the other end of the gas channel is a free end that can be sealed, and is used to connect the test host, and when detecting body cavity pressure, it can communicate with the second air vent and The test host. The above technical solution realizes a convenient and fast pressure test without performing separation-conduction operation, which improves the detection efficiency.

Description

Technical field [0001] The present disclosure relates to the technical field of medical devices, specifically related to a barometric pressure regulation mechanism for measuring body cavity pressure, a detection catheter and a detection device. Background [0002] With the large-scale outbreak of the global epidemic, for a large number of severe and critically ill patients with severe and critical illness of new crown pneumonia who have respiratory failure or even progress to acute respiratory distress syndrome (ARDS), the main treatment method is to use ventilators and other equipment to help patients maintain breathing, ensure the body's oxygen supply, and buy time for the recovery of the immune system and the implementation of other treatment methods. [0003] In mechanical ventilation in patients with respiratory failure / acute respiratory distress syndrome, how to achieve a balance of interests between reducing alveoli collapse and preventing excessive lung expansion remains ...
