The following describes in detail that the fixing strap 1 is wrapped around the patient’s abdomen. It is understood that the fixing strap 1 can also be wrapped around other parts of the patient’s body. And detect the movement of the corresponding parts. The airbag 2 is fixedly connected to the fixed strap 1, and the airbag 2 is fixed on the designated part of the patient's body through the fixed strap 1. By detecting the pressure change of the airbag 2, the abdominal movement of the patient can be obtained; one end of the tracheal joint 6 is connected to the airbag 2 connected, the other end is used to communicate with an external device (such as a pressure detection device), so that the external device is communicated with the airbag 2, so that the external device can detect the air pressure change of the airbag 2; the positioning mark 3 is arranged on the outer surface of the fixing strap 1, It is convenient to determine the placement position of the airbag 2 on the patient's body. Preferably, the positioning mark 3 is facing the airbag 2 to improve the positioning accuracy of the airbag 2; the scale mark 4 is arranged on the outer surface of the fixing strap 1. When the fixing strap 1 is wound, the positioning Mark 3 coincides with scale mark 4, and the length of the wrapping of the fixing strap 1 can be read, so as to control the tightness of the fixing strap 1 and ensure that the airbag 2 is under the same pressure condition when used multiple times. Because the respiratory gating device provided in the present application can complete and precisely control the position fixation and pressure adjustment of the airbag 2 in one operation, the operation and operation of the respiratory gating device is simplified, and the detection accuracy of the respiratory gating device is improved.

Specifically, the fixing strap 1 can be set to any length to suit patients of different body types, preferably, the length of the fixing strap 1 is 100cm-200cm, so as to suit the body type of most patients. More preferably, the fixing strap 1 can be set into various length specifications by section, for example, two specifications of 120cm and 160cm, when the patient is small, the 120cm specification is used, and when the patient is large, the 160cm specification is used. The width of the fixing strap 1 is preferably 10 cm-15 cm, so that the fixing strap 1 can fit the body of the patient more easily and satisfy the comfort requirement.

Preferably, the fixing strap 1 is made of soft inelastic material, such as leather or cloth. On the one hand, the use of a soft material enables the fixing strap 1 to fit the patient's body without damaging the patient's body, thereby improving the comfort of the fixing strap 1; The determined tightness does not cause the pressure change of the airbag 2 caused by the elasticity of the fixing strap 1 itself, so as to ensure the accuracy of the detection result.

Preferably, the fixing structure adopted by the fixing strap 1 is a sticking structure, such as a Velcro, which can continuously adjust the tightness of the fixing strap 1 and has better adaptability, and the sticking structure is relatively soft as a whole, so that the fixing strap 1 can be wrapped around Better comfort for the patient's body. When the sticking structure is adopted, the piece with the hook hair in the sticking structure is arranged on the inner surface of one end of the fixing strap, and the piece with fluff in the sticking structure is arranged on the outer surface of the other end of the fixing strap, and the piece with the fuzz is arranged on the outer surface of the other end of the fixing strap The length of one piece is longer than that of the piece with hook hairs, so that when the fixing strap 1 is wrapped around the patient's body, the hook hairs are not exposed, so as to avoid scratches. It can be understood that the above-mentioned fixing structure may also be any existing fixing structure such as hooks, buttons, snaps or pins.

Specifically, the airbag 2 can be arranged at any position of the first circle formed by the winding of the fixing strap 1, that is, when the fixing strap 1 is wound around the patient's body, the airbag 2 can be in contact with the patient's body, so as to fully detect The patient's abdominal movements.

Preferably, as shown in FIG. 4 , the air bag 2 is arranged at one end of the fixing strap 1 . When the fixing strap 1 is wrapped around the patient’s body, the part where the air bag 2 is located has the maximum thickness of the fixing strap 1 , and the air bag 2 is increased. Fixed reliability.

Preferably, along the length of the fixing strap 1, the size of the airbag 2 is 15cm-20cm, so that the airbag 2 covers the area to be measured on the patient's abdomen, which can not only effectively detect the movement of the patient's abdomen, but also avoid detecting too many interference signal. Preferably, the airbag 2 extends along the width direction of the fixing strap 2 to the edge of the fixing strap 1 , so as to improve the effective utilization of the fixing strap 2 and improve the sensitivity of the airbag 2 .

Further, the inside of the airbag 2 may be filled with sponge. Airbag 2 can use an inflatable airbag. Because the abdominal movement caused by the patient's breathing is relatively weak, the sensitivity of the inflatable airbag is low, and it takes a long time to deform or restore the deformation under the action of the air of the airbag 2, resulting in the air pressure detected by the external equipment and the airbag There is a delay between the actual air pressure of 2. By filling the sponge in the air bag 2, the sponge deforms or recovers quickly with the patient's breathing, and the sensitivity is high, shortening the delay between the air pressure detected by the external device and the actual air pressure of the air bag 2, and improving the detection accuracy , and the manufacture is convenient and the cost is reduced.

Preferably, as shown in FIG. 3 , the scale mark 4 is arranged on the end of the fixing strap 1 away from the airbag 2 . When the two ends of the fixing strap 1 are slightly overlapped, the length of the winding of the fixing strap 1 can be read, thereby Make the most of the effective length of the securing strap 1. It can be understood that the scale mark 4 can also leave a gap with the end of the fixing strap 1 away from the airbag 2 .

Specifically, the scale mark 4 can be in any form such as line type or point type, preferably a line type, which is easy to read and has high accuracy, and the scale mark 4 can be a notch or a drawn mark. When the line type is adopted, the scale marks 4 extend along the width direction of the fixing strap 1 and are sequentially arranged along the length direction of the fixing strap 1 to form a longer scale range. The length of the scale marks 4 arranged along the length direction of the fixing strap 1 may be only a length region of the fixing strap 1 , or may be the entire length range of the fixing strap 1 . Specifically, along the length direction of the fixing strap 1 , the scale marks 4 may be identical, or two or more different scale marks 4 may be distributed at intervals.

Further, the distance between adjacent scale marks 4 is 0.5cm-1cm, that is to say, the tightness adjustment accuracy of the fixing strap 1 is 0.5cm-1cm, which not only satisfies the tightness adjustment requirement of the fixing strap 1, but also Not to introduce too small measurement accuracy, increase the complexity of manufacturing and operation.

Further, the position corresponding to the scale mark 4 on the fixing strap 1 is provided with a scale viewing window 40, and the scale viewing window 40 adopts a hollow structure or a transparent structure, and the positioning overlapping on the inner side of the scale viewing window 40 can be seen through the scale viewing window 40.

The central position of the cross mark or the rice mark can facilitate the positioning of the airbag 2 and improve the accuracy of the placement position of the airbag 2. The cross mark or the rice mark is along the fixing strap. The line extending in the width direction of 1 is easy to coincide with the scale mark 4, which improves the accuracy of pressure adjustment. In addition, when the fixing strap 1 is wound around the patient's body, it may be inclined. When the length of the fixing strap 1 is not changed, the different inclination angles will lead to different tightness of the fixing strap 1, so that the airbag 2 Under different pressure conditions, the two ends of the line extending along the width direction of the fixed strap 1 with the cross mark or the rice mark are overlapped with the same scale mark, which can effectively prevent the fixed strap 1 from tilting, thereby ensuring that the airbag 2 is at the same pressure conditions.

Further, as shown in FIG. 2 , the respiratory gating device provided by the present application may further include one or more auxiliary straps 5 for realizing the limiting effect on the fixed strap 1 , the auxiliary strap 5 and the fixed strap There is an included angle between 1, for example, the fixing strap 1 is wound around the patient's abdomen and fixed on the patient's abdomen, and the auxiliary strap 5 is fixed on the patient's shoulder along the patient's height direction, so as to adjust the air bag in two different directions. 2 position and pressure to further improve the detection accuracy.

Preferably, the auxiliary strap 5 and the fixed strap 1 are vertically arranged to determine the vertical position of the fixed strap 1. When in use, there is no need to adjust the angle between the auxiliary strap 5 and the fixed strap 1.

It further simplifies the use and operation, avoids the error generated during the angle adjustment process, and improves the detection accuracy.

Specifically, the length and width of the auxiliary strap 5 can be reasonably designed according to the actual situation and design requirements, and the auxiliary strap 5 can be designed to have a structure similar to that of the fixed strap 1. For example, the auxiliary strap 5 can adopt the same structure as the fixed strap 1. Made of the same material.
