[0002] With the continuous development of medical technology, the requirements for the multifunctionality and compatibility of medical equipment are becoming increasingly stringent. Especially in the field of respiratory anesthesia, patients need to receive oxygen supply, have their vital signs monitored (such as blood pressure and blood oxygen saturation), and undergo respiratory anesthesia procedures simultaneously. Therefore, a multifunctional oxygen mask that can meet these needs at the same time has become an urgent need in clinical practice.
[0003] In the existing medical respiratory anesthesia examination compatible oxygen mask, most of them use a thick tube inserted into a thin tube at the tracheal connection. This connection method results in poor airtightness and instability at the connection, which affects the patient's oxygen inhalation experience.
[0004] Therefore, a medical respiratory anesthesia examination compatible oxygen mask is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a medical respiratory anesthesia examination compatible oxygen mask, which aims to improve the problems of poor airtightness at the tracheal connection and inability to adjust the tightness of the fixing rope.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a medical respiratory anesthesia examination compatible oxygen inhalation mask, comprising a mask body, a Y-shaped tube fixedly connected to the bottom of the mask body, a first convex ring fixedly connected to the outer side of the Y-shaped tube, a second convex ring fixedly connected to the inside of the Y-shaped tube, an air inlet tube slidably connected to the inside of the Y-shaped tube, a second concave ring provided on the outer side of the air inlet tube, a shell fixedly connected to the outer side of the air inlet tube, a first concave ring provided on the inner wall of the shell, and an adjustment component for adjusting the tightness of the mask provided on the outer side of the mask body.
[0007] As a further description of the above technical solution:
[0008] The adjustment component includes a fixing block, which is fixedly connected to the outside of the mask body. A fixing rope is fixedly connected to the outside of the mask body. A pin is slidably connected inside the fixing block. A pull rod is fixedly connected to one end of the pin. A spring is sleeved on the outside of the pull rod. The end of the fixing rope is provided with teeth.
[0009] As a further description of the above technical solution:
[0010] The first and second convex rings are made of rubber, and the inner wall of the casing is slidably connected to the outside of the Y-shaped tube.
[0011] As a further description of the above technical solution:
[0012] A valve is fixedly connected to the outside of the Y-shaped tube, and a sealing gasket is fixedly connected to the inside of the concave ring.
[0013] As a further description of the above technical solution:
[0014] The outer side of the second convex ring is engaged with the inside of the second concave ring, and the outer side of the first convex ring is engaged with the inside of the first concave ring.
[0015] As a further description of the above technical solution:
[0016] One end of the spring is fixedly connected to one side of the pin, and the other end of the spring is fixedly connected to the inner wall of the fixing block.
[0017] As a further description of the above technical solution:

[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, when the air intake pipe needs to be connected to the Y-shaped pipe, the air intake pipe is directly inserted into one of the openings of the Y-shaped pipe to be connected. Since the Y-shaped pipe has convex rings fixed on both the outside and inside, and the air intake pipe and the housing have concave rings, they will be interference fit when inserted, making the connection more stable and the airtightness better.
[0023] 2. In this utility model, when the wearer puts on the mask, the tightness of the mask can be adjusted by pulling the fixing rope, so that the wearer is in a comfortable wearing state. Due to the toothed design at the end of the fixing rope and the rounded bevel design at one end of the pin, the fixing rope can only slide in the tight direction. When it is necessary to loosen, simply pull the disc to make the pin disengage from the toothed pattern, which effectively improves the wearer's comfort and makes it more convenient to put the mask on the wearer.

The mask body 1 is the basic part of the oxygen mask, which is in direct contact with the patient's face. It is used to seal and cover the nose and mouth to ensure that oxygen can be effectively delivered to the patient's respiratory tract. The fixing rope 2 is used to fix the mask body 1 to the wearer. The pin 15 is used to abut against the teeth at the end of the fixing rope 2 to ensure that the fixing rope 2 can only move in one direction. The pull rod 13 is used to pull the pin 15. The spring 16 is used to ensure that the pin 15 will be tightly abut against the fixing rope 2 when there is no external force.
[0034] Reference Figure 1 , Figure 4 and Figure 5 The first convex ring 5 and the second convex ring 11 are made of rubber. The inner wall of the housing 9 is slidably connected to the outside of the Y-shaped tube 3. The first convex ring 5 and the second convex ring 11 are used to engage with the first concave ring 10 and the second concave ring 7 on the intake pipe 8 and the housing 9.
[0035] Reference Figure 1 , Figure 4 and Figure 5 A valve 4 is fixedly connected to the outside of the Y-shaped tube 3, and a sealing gasket 6 is fixedly connected inside the concave ring 7. The Y-shaped tube 3 serves as a bridge connecting the mask body 1 with the external oxygen supply system and anesthetic. The valve 4 is used to control the opening and closing of the Y-shaped tube 3, and the sealing gasket 6 makes the airtightness between the Y-shaped tube 3 and the air inlet pipe 8 better.
[0036] Reference Figure 4 and Figure 5 The outer side of the second convex ring 11 is engaged with the inner side of the second concave ring 7, and the outer side of the first convex ring 5 is engaged with the inner side of the first concave ring 10. The first convex ring 5 and the second convex ring 11 are used to engage with the first concave ring 10 and the second concave ring 7 on the intake pipe 8 and the housing 9, so that the connection between the Y-shaped pipe 3 and the intake pipe 8 is more stable.
[0037] Reference Figure 3 One end of the spring 16 is fixedly connected to one side of the pin 15, and the other end of the spring 16 is fixedly connected to the inner wall of the fixing block 12.

[0039] Reference Figure 1 - Figure 3 The end of the pin 15 that abuts against the fixing rope 2 has a rounded bevel. The rounded bevel of the pin 15 is designed so that the pin 15 can slide in one direction of the teeth at the end of the fixing rope 2.
[0040] Working principle: First, the mask body 1 is put on by the wearer. Then, the tightness of the fixing rope 2 is adjusted by pulling it to ensure a comfortable wearing position. Due to the toothed design at the end of the fixing rope 2 and the rounded bevel design at one end of the pin 15, the fixing rope 2 can only slide in the tight direction. When it is necessary to loosen the fixing rope 2, simply pull the disc 14. The pull rod 13 connected to the disc 14 will pull the pin 15, causing the pin 15 to disengage from the toothed pattern. This allows the fixing rope 2 to move in the loosening direction. To adapt to the wearing requirements of different wearers, the comfort of the wearer is effectively improved, and it is also more convenient to put the mask on the wearer. When connecting the air inlet pipe 8, the air inlet pipe 8 is directly inserted into one of the ports of the Y-shaped pipe 3 to be connected. Since the Y-shaped pipe 3 has convex rings fixed on the outside and inside, and the air inlet pipe 8 and the housing 9 have concave rings inside, they will be interference fit when inserted and connected together. Moreover, the sealing gasket 6 is fixed inside the housing 9, which makes the connection more stable and the airtightness better. Then, the corresponding valve 4 on the pipe is opened.
