Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Specific examples are given below.

[0026] See also Figure 1-Figure 5 The utility model provides an artificial airway bag pressure monitoring device, including a pressure measuring device 1, a three-way pipe 2 is inserted and connected at the rear of the pressure measuring device 1, a connecting hose 3 is inserted and connected at the middle of the three-way pipe 2, and an air supply structure 4 is inserted and connected at the distal end of the connecting hose 3.

[0027] Further, such as Figure 2-Figure 4As shown, the pressure measuring device 1 includes a fixed cylinder 11, the rear portion of the outer surface of the fixed cylinder 11 is threadedly connected to a connecting cover 12, the middle portion of the rear end of the connecting cover 12 is fixedly connected to an external pipe 13, the middle portion of the front end of the fixed cylinder 11 is fixedly connected to an extension pipe 14, the inside of the fixed cylinder 11 is slidably connected to a push plate 15, the middle portion of the front end of the push plate 15 is fixedly connected to a benchmark 16, the outer surface of the benchmark 16 is fixedly connected to a number of equally distributed pressure scales 17, a pressure spring 18 is provided on the outside of the benchmark 16, the outer surface of the push plate 15 is in contact with the inner surface of the fixed cylinder 11, the benchmark 16 is located inside the extension pipe 14, the pressure spring 18 is located between the push plate 15 and the fixed cylinder 11, the three-way pipe 2 includes a first fixed pipe 21, the middle portion of the outer surface of the first fixed pipe 21 is fixedly connected to a second fixed pipe 22, the rear end of the first fixed pipe 21 is fixedly connected to a first connecting pipe 23, a three-way ball valve 24 is provided at the position of the second fixed pipe 22 inside the first fixed pipe 21, and the first fixed pipe 21 is interlaced with the external pipe 13.

[0028] Through the above scheme: by providing a push plate 15 that fits with the fixed cylinder 11 in the pressure measuring device 1, when the device is used, the air entering the airway tube bag will be fed back into the pressure measuring device 1, and push the push plate 15 in the pressure measuring device 1, so that the mark 16 on one side of the push plate 15 is pushed out of the fixed cylinder 11, and the operator can directly observe the pressure scale mark 17 on the upper part of the mark 16 to understand the gas pressure filled in the airway tube bag, thereby avoiding excessive pressurization causing damage to the patient's airway, and the three-way ball valve 24 arranged inside the three-way pipe 2 in the device can close the passage between the pressure measuring device 1 and other components after the pressure measurement is completed using the device, so as to reduce the occurrence of gas leakage in the airway tube bag.

[0029] Further, such as Figure 5 As shown, the air supply structure 4 includes a third fixed tube 41, the right end of the third fixed tube 41 is fixedly connected to a pressure airbag 42, a one-way air valve 43 is provided on the right side of the outer surface of the pressure airbag 42, the left end of the third fixed tube 41 is fixedly connected to a second connecting tube 44, the middle part of the outer surface of the third fixed tube 41 is fixedly connected to a fourth fixed tube 45, the end of the fourth fixed tube 45 away from the third fixed tube 41 is interlaced with a sealing cover 46, and the connecting hose 3 is interlaced with the second fixed tube 22 and the second connecting tube 44.

[0030] Through the above scheme: when the device is in use, the air supply structure 4 can inflate the air bag in the connected airway cannula by squeezing the pressure air bag 42, and prevent the gas filled into the airway cannula air bag from being lost through the provided one-way air valve 43.

[0032] In actual application, the user only needs to simply connect the first connecting tube 23 of the three-way pipe 2 with the airbag connecting tube of the airway tube, and then manually press the pressure airbag 42 in the air supply structure 4 to easily inject the required gas into the airbag of the airway tube. As the gas is filled, the pressure change inside the airbag will be immediately reflected on the pressure measuring device 1. Specifically, the push plate 15 moves in the fixed cylinder 11 and pushes the mark 16 up, so that the user can directly read the clear pressure scale 17 on the mark 16 to accurately know the gas pressure value in the airbag;

[0033] If fine-tuning of the air pressure in the airbag of the airway tube is required, this device also provides a convenient solution. By operating the sealing cap 46 on the fourth fixed tube 45 of the air supply structure 4, the user can easily control the deflation process and achieve precise adjustment of the air pressure inside the airbag. This design not only simplifies the operation process, but also greatly improves the flexibility and safety of use.

[0034] It is particularly worth mentioning that the structural design of this device fully considers ease of use, economy and hygiene. It has a simple structure, low production cost, and each component can be completely disassembled, which facilitates thorough cleaning, disinfection and sterilization after use, effectively avoiding the risk of cross infection, while also saving procurement and maintenance costs for the hospital.

[0035] The above shows and describes the basic principles, main features and advantages of the present invention.
