[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 4As shown, the utility model provides a fixed respiratory gated breathing tube fixing device, including two clamping mechanisms 1, the clamping mechanisms 1 constitute a snap-fit ​​structure that can be buckled on both ends of the treatment bed, the two clamping mechanisms 1 include a clamping shell 101, and the upper ends of the two clamping shells 101 are each provided with a rectangular upper cavity 102, and the two clamping mechanisms 1 also include rectangular limit blocks 103 symmetrically fixed on both sides of the inner cavity of the upper cavity 102, and both ends of the U-shaped rod 3 are provided with longitudinal grooves 4, and the limit blocks 103 slide in the longitudinal grooves 4 and can achieve limiting. It should be noted that a resistance pad is glued and fixed to the inner wall of the longitudinal groove 4 and abuts against the surface of the limit block 103, thereby increasing the resistance of the limit block 103 sliding inside the longitudinal groove 4, so that the U-shaped rod 3 can be stopped at any position, and at the same time, the longitudinal groove 4 can achieve the limiting effect on the limit block 103.

[0022] Rectangular transverse grooves 5 are provided on both sides of the middle of the U-shaped rod 3, and protrusions 2 are fixed on the opposite sides of the lower end of the movable seat 6. The two protrusions 2 are slidably set in the transverse grooves 5. The lower end surface of the middle part of the movable seat 6 fits with the upper end surface of the U-shaped rod 3 to reduce the gap and avoid shaking. The upper end of the movable seat 6 is fixed to the flexible bracket 7, and the end of the flexible bracket 7 away from the movable seat 6 is fixed with a clamp 8 for fixing the breathing valve. The clamp 8 is detachably plugged into the breathing valve, and one port of the breathing valve is connected to the breathing tube. Because the connection method between the breathing valve and the clamp 8 is an existing and conventional installation, it will not be described in detail.

[0023] The flexible bracket 7 is an existing and mature technology, which is the same as the existing mobile phone bracket structure that can be adjusted arbitrarily, and will not be described in detail.

[0024] The lower ends of the two clamping shells 101 are provided with a lower cavity 107. The shape and structure of the clamping shells 101 are as follows: Figure 3 As shown, both sides of the lower end of the clamping shell 101 are provided with extended protrusions and the protrusions are chamfered with arcs. A rotating shaft is inserted and fixed in the upper part of the inner cavity of the clamping shell 101, and the rotating shaft movably passes through the middle part of the trigger 104. The structure of the trigger 104 (such as Figure 4 As shown), a rotating shaft is fixedly passed through the lower part of the inner cavity of the clamping shell 101, and the middle part of the rotating shaft is hinged with one end of the arc-shaped claw 106 that can be movably passed through. The lower end of the clamping shell 101 constitutes the clamping arc-shaped claw 106, and the lower end of the clamping shell 101 is set as a plane. One end of two connecting rods 105 are respectively rotatably set on both sides of the trigger 104 and movably pass through the rotating shaft, and the other end of the connecting rod 105 is fixedly connected to both sides of the arc-shaped claw 106 close to one end of the rotating shaft.

[0025] Silicone pads 9 are embedded in the upper and lower ends of the two protrusions 2. The silicone pads 9 protrude from the end faces of the protrusions 2 and abut against the surface of the transverse grooves 5, thereby increasing the movement resistance so that the movable seat 6 can be moved to any position of the U-shaped rod 3 and fixed. The silicone pads 9 protrude from the end faces of the protrusions 2 by 2 mm.

[0026] It should be noted that Figure 1 It is the clamping state of the clamping mechanism 1.

[0027] Principle and process of this utility model:

[0028] Under normal conditions, the trigger 104 of the clamping mechanism 1 of the device is away from the clamping shell 101 so that the arc-shaped claw 106 is away from the lower end of the clamping shell 101, thereby achieving an open state.

[0029] When using the device, the two sides of the treatment bed are respectively inserted between the arc-shaped claws 106 and the clamping shell 101. Since the width of the treatment bed is standard, installation can be achieved. Then, the user presses the trigger 104 by hand to make it fit with the surface of the clamping shell 101. At this time, the trigger 104 rotates with the shaft as the rotation axis and drives the arc-shaped claws 106 to rotate on the shaft through the connecting rod 105, so that the arc-shaped claws 106 rotate toward the lower end position of the clamping shell 101, thereby realizing the clamping function. This operation forms a snap-on clamping, so the breathing tube fixing device can be firmly fixed on the treatment bed, and it will not fall and hit the patient or affect the treatment progress due to falling.

[0030] When the height of the U-shaped rod 3 needs to be adjusted, the user only needs to pull the U-shaped rod 3 by hand to make the longitudinal groove 4 slide outside the limit block 103 to prevent the U-shaped rod 3 from separating from the clamping shell 101, and the friction force of the resistance pad allows the U-shaped rod 3 to stay at the desired height.

[0031] When a certain position of the breathing tube is required, the user holds the movable seat 6 by hand and moves it on the U-shaped rod 3 to adjust the lateral position. At the same time, the setting of the silicone pad 9 can increase the friction between the protrusion 2 and the inner wall of the horizontal groove 5, thereby achieving a fixing effect. This setting can avoid interference with external equipment, thereby adapting to the special positioning of the patient.

[0032] In summary, the device is provided to facilitate the therapist to position the patient, and the treatment will not be suspended or interrupted due to the instability of the device.

[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
