Description

Technical Field

[0001] The invention belongs to the technical field of medical auxiliary equipment, and in particular relates to a groin puncture fixation device for children with heart disease. Background Art

[0002] Congenital heart disease is the most common type of congenital malformation, referred to as CHD. Cardiac interventional surgery is one of the most effective means of treating congenital heart disease. The approach for interventional surgery is generally in the groin, with only a small skin incision of 0.5cm-0.8cm. The catheter is introduced into the blood vessel through puncture, and the catheter can enter the heart along the blood vessel. After necessary routine examinations of the heart, further diagnosis and precise measurement of the condition, the instrument can be sent to the site to be treated for treatment.

[0003] After cardiac interventional surgery, it is necessary to use a fixation device to immobilize the lower limbs of the surgical patient, that is, to use a fixation device to fix the legs of the surgical patient. However, most patients who undergo interventional treatment for congenital heart disease are children. This is because congenital heart disease will affect growth and development, and affect lung development, so it is necessary to perform surgical treatment on the patient as soon as possible. Compared with postoperative lower limb immobilization for adults, when performing postoperative lower limb immobilization on child patients, because the child patients are not mentally mature, if the fixation is not firm, the child patients have poor autonomy, and their lower limbs are not restrained and will move around, causing related complications, and then causing braking failure. If it is fixed for a long time, it will increase the child patient's severe discomfort, which will inevitably cause the child patient to have more serious disgust and resistance, and then resist braking. In severe cases, it will also cause related complications, and then cause braking failure. Therefore, the fixation device in the prior art is difficult to perform reasonable lower limb immobilization on child patients after cardiac interventional surgery.

[0004] For example, a Chinese patent with announcement number CN106618906B discloses a lower limb braking and fixation device for use after vascular intervention surgery, which achieves braking of the patient's lower limbs through a bracket and a compression device installed on the bracket. It can be seen that it only relies on the compression device to compress the patient's lower limbs, and does not perform any other limiting or fixation. For children with poor self-control, it cannot guarantee effective lower limb braking. When the child's lower limbs are not restrained during movement, it will directly lead to braking failure. Therefore, it cannot reasonably perform lower limb braking on child patients after cardiac intervention surgery. Another example is a Chinese patent with announcement number CN219629890U that discloses a pediatric heart disease groin puncture fixation device, which fixes the waist and legs of child patients respectively through a waist support and a leg support. However, in actual use, since the children are not mentally mature, if they are fixed for a long time, they will inevitably have more serious disgust and resistance emotions, and then they will resist braking. In severe cases, they will resist and move around at will, which will further increase the discomfort and be more likely to cause related complications, resulting in braking failure. Therefore, it is not possible to reasonably perform lower limb braking on child patients after heart disease interventional surgery. Summary of the invention

[0005] In view of the above-mentioned problems, the purpose of the present invention is to provide a groin puncture and fixation device for pediatric heart disease, which can reasonably perform lower limb immobilization on pediatric patients after heart disease interventional surgery, and can effectively avoid long-term immobilization of pediatric patients, which may cause severe discomfort, disgust and resistance, and then resistance to immobilization.

[0006] The technical solution of the present invention is: a groin puncture fixation device for children with heart disease, including a restraint component for restraining the child patient during lower limb braking after cardiac intervention surgery; and also includes a data acquisition component and a control component.

[0007] The data acquisition component is used to collect the human motion data of the child patient in real time. The control component is electrically connected to the data acquisition component, and is used to receive and process the human motion data collected by the data acquisition component to determine whether the lower limb of the child patient at the puncture site has any motion behavior.

[0008] The constraint assembly includes a mounting member, a limiting member, a deformation member and a driving member.

[0009] The mounting part is fixed on the bed when braking the child's lower limbs. The limiting part is arranged on the mounting part, and is used to limit the waist and lower limbs of the child patient at the puncture site. A gap is formed between the limiting part and the body surface of the waist and lower limbs of the child patient at the puncture site. The deformable part is arranged on the limiting part, and is located at the gap. The driving part is connected to the deformable part, and is used to drive the deformable part to deform; the driving part is electrically connected to the control component, and when the control component determines that the child patient's lower limbs have movement behavior, the driving part drives the deformable part to deform to fix the child patient's waist and lower limbs at the puncture site.

[0010] When in use, the child patient's waist and lower limbs at the puncture site are limited by the limiting parts. It should be noted that the limiting parts at this time do not fix the child patient. The child patient does not contact the limiting parts while maintaining the unchanged body position, and a gap is formed between the limiting parts and the child patient. At this time, the child patient is not actually restrained, and there is no discomfort caused by fixation. The data acquisition component collects the child patient's human body motion data in real time. When the control component determines that the child patient's lower limb at the puncture site has movement behavior, the driving part is used to drive the deformable part to deform to fill the gap. The limiting part and the deformed deformable part constitute a fixing part, which is used to fix the child patient to form an actual restraint.

[0011] Furthermore, the data acquisition component includes a sensing component and a photographing component.

[0012] The sensing component is electrically connected to the control component, and is used to collect relevant signals of the child patient's human body movements in real time. The shooting component is electrically connected to the control component, and is used to collect graphic information of the child patient in real time. The data collected by the data acquisition component is used as the starting signal source for the control component to start the driving component to drive the deformable component to deform. Therefore, the sensing component is used in conjunction with the shooting component to synchronously collect signals. In actual use, the sensing component is used for initial data monitoring. When the sensing component senses data changes, the shooting component further confirms whether there is any action through the captured graphic information. Therefore, the cooperation between the sensing component and the shooting component can more accurately determine whether the child patient's lower limbs have any action.

[0013] Furthermore, the sensing component includes one or more of a pressure sensor, an angle sensor, and a distance sensor.

[0014] The pressure sensor can be arranged on the bed to monitor the pressure exerted by the child patient on the bed. Specifically, a commercially available resistive pressure-sensitive fabric sensor is used. In actual use, the control component is used to monitor the pressure change signal exerted by the child patient on the bed to further predict and monitor whether the child patient has any action.

[0015] The angle sensor can be arranged at the groin of the puncture site of the child patient to monitor the angle between the lower limbs and the waist of the child patient at the puncture site. Specifically, a commercially available flexible joint motion angle optical fiber sensor is used. In actual use, the angle between the lower limbs and the waist of the child patient at the puncture site is monitored in cooperation with the control component, and this is used as a basis for judging the movement behavior of the lower limbs of the child patient.

[0016] The distance sensor can be set at the groin position and the lower limb position of the puncture site of the child patient to monitor the distance between the groin position and the lower limb position of the puncture site of the child patient and the reference position. Specifically, a commercially available infrared distance measuring sensor is used. In actual use, the distance sensor can be installed on the bed, and the foot corresponding to the puncture site of the child patient is used as a reference to monitor the distance from the fixed point of the bed to the foot, which is used as a basis for judging the movement behavior of the child patient's lower limbs.

[0017] In actual use, one or more types are used in combination. If multiple types are used in combination, the sensor that detects the changes is used as the basis to cooperate with the camera to determine whether the child patient has any action or behavior.

[0018] Furthermore, the mounting member includes a first mounting member and a second mounting member. There are two first mounting members, which are spaced apart on the bed and located on both sides of the middle section of the bed surface; there are two second mounting members, which are spaced apart on the bed and located on both sides of the lower section of the bed surface.

[0019] The limiting member includes a first limiting member and a second limiting member. There are two first limiting members, which are arranged on two first mounting members in a one-to-one correspondence, and are used to limit the waist of the child patient; the second limiting member is installed on any second mounting member, and is used to limit the lower limbs of the child patient at the puncture position.

[0020] The waist and leg limiter components are set independently, which can effectively reduce the effective fixation area of ​​the child patient in actual use, avoiding the overall structural components causing large-area fixation of the child patient and causing more severe discomfort. In addition, the two independent components are also more convenient for medical staff to operate in actual use.

[0021] Furthermore, the first mounting member includes a first mounting rod and a mounting base plate. One end of the first mounting rod is slidably arranged on the bed, and the bed is provided with a first slide groove corresponding to the first mounting rod. The mounting base plate is rotatably arranged on the other end of the first mounting rod, and the mounting base plate is an arc-shaped structure; the first limit member is arranged on the mounting base plate.

[0022] Furthermore, the first limiter includes an adjustment rod and a first base. There is at least one adjustment rod, which is threaded on the mounting base; the adjustment rod can adjust the length of the mounting base close to the bed through the thread; the first base corresponds to the adjustment rod and is arranged on the adjustment rod, and is located at one end of the adjustment rod close to the bed.

[0023] The gap is the gap between the mounting base and the child patient. The width of the gap can be adjusted according to different child patients or different braking requirements by adjusting the length of the adjusting rod located on the side of the mounting base close to the bed, which has a wider range of applicability in actual use.

[0024] Furthermore, the second mounting member includes a base and a second mounting rod. The base is slidably arranged on the bed, and the bed is provided with a second slide groove corresponding to the base. There are two second mounting rods, which are arranged on the base at intervals and located on both sides of the base; and the second stopper is arranged on the second mounting rod.

[0025] Furthermore, the second limiting member includes two limiting plates, which are rotatably arranged on the two second mounting rods in a one-to-one correspondence, and the two limiting plates are clamped together. Before use, after the two limiting plates are rotated to positions away from each other, the child patient places the lower limbs on the base and between the two second mounting rods, and then the two limiting plates are reset and clamped together.

[0026] Furthermore, the deformable member includes a mounting disc seat and a bladder body. There is at least one mounting disc seat, which is fixedly arranged on the limiting member. The bladder body corresponds to the mounting disc seat and is sleeved on the mounting disc seat; the bladder body and the mounting disc seat constitute an inflatable deformation chamber; the driving member is an inflation and deflation device, which is connected to the inflatable deformation chamber and adjusts the actual shape of the inflatable deformation chamber by gas. In actual use, when the driving member inflates the inflatable deformation chamber, the actual shape of the inflatable deformation chamber can be quickly changed, and the bladder body also has a certain cushioning property, and will not generate a large impact force on the body surface of the child patient after inflation, thereby having a higher safety. In addition, due to the characteristic that the bladder body can be deformed under pressure after the inflatable deformation chamber is inflated, it is also more comfortable when fixing the child patient.

[0027] Furthermore, the mounting plate is arranged on the limiting member through an elastic member, and the elastic member improves the buffering performance of the structure, further avoiding unnecessary damage caused by a large impact force on the body surface of the child patient.

[0028] The working method of the present invention: When in use, the child patient's waist and lower limbs at the puncture site are limited by a limiting member. It should be noted that the limiting member at this time does not fix the child patient. The child patient does not contact the limiting member while maintaining the unchanged body position, and thus a gap is formed between the limiting member and the child patient. At this time, the child patient is not actually restrained, and thus there is no discomfort caused by fixation. The data acquisition component collects the child patient's human body motion data in real time. When the control component determines that the child patient's lower limb at the puncture site has a movement behavior, the driving member is used to drive the deformable member to deform to fill the gap. The limiting member and the deformed deformable member constitute a fixing member, and the fixing member is used to fix the child patient to form an actual restraint.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] The present invention utilizes a data acquisition component to collect the human motion data of the child patient in real time, and utilizes a control component to receive and process the human motion data to determine whether the child patient's lower limb at the puncture site has any motion behavior. When the child patient has no motion behavior, the restraint component does not contact the child patient's body surface, and therefore does not cause discomfort to the child patient. When the child patient has any motion behavior, the drive member drives the deformation member to deform, and the child patient is quickly fixed and restrained to achieve braking of the lower limb at the puncture site, which greatly reduces the actual restraint time for the child patient, and effectively avoids long-term fixation of the child patient to cause serious discomfort, causing him to have aversion and resistance, and then seriously resist braking and move around, resulting in braking failure.

[0039] It should be noted that the circuit connections involved in the present invention all adopt conventional circuit connection methods and do not involve any innovation.

[0040] Example 1

[0041] like Figure 1 , Figure 2 , Figure 3 The groin puncture fixation device for pediatric heart disease shown in the figure includes a restraint component 1, which is used to restrain the child patient during lower limb braking after cardiac intervention surgery; it also includes a data acquisition component 2 and a control component 4.

[0042] The data acquisition component 2 is used to collect the human motion data of the child patient in real time. The control component 4 is electrically connected to the data acquisition component 2, and is used to receive and process the human motion data collected by the data acquisition component 2 to determine whether the lower limb of the child patient at the puncture site has any motion behavior.

[0043] The restraining assembly 1 includes a mounting member 11 , a limiting member 12 , a deforming member 13 and a driving member 14 .

[0044] The mounting member 11 is fixed on the bed 3 when braking the child's lower limbs. The limiting member 12 is arranged on the mounting member 11, and is used to limit the waist and the lower limbs of the child patient at the puncture position. A gap is formed between the limiting member 12 and the body surface of the waist and the lower limbs of the child patient at the puncture position. The deformation member 13 is arranged on the limiting member 12, and is located in the gap. The driving member 14 is connected to the deformation member 13, and is used to drive the deformation member 13 to deform; the driving member 14 is electrically connected to the control component 4. When the control component 4 determines that the child patient's lower limbs have movement behavior, the driving member 14 drives the deformation member 13 to deform to fix the child patient's waist and the lower limbs at the puncture position.

[0045] The groin puncture fixation device for children with heart disease is used to immobilize the lower limbs after puncture surgery in the groin area. When in use, the limiting member 12 is used to limit the waist and the lower limbs of the child patient at the puncture site. It should be noted that the limiting at this time does not fix the child patient. The child patient does not contact the limiting member 12 while maintaining the unchanged body position, and a gap is formed between the limiting member 12 and the child patient. At this time, the child patient is not actually restrained, and there is no discomfort caused by fixation. The data acquisition component 2 collects the human body motion data of the child patient in real time. When the control component 4 determines that the lower limb of the child patient at the puncture site has a movement behavior, the driving member 14 is used to drive the deformable member 13 to deform and fill the gap. The limiting member 12 and the deformed deformable member 13 constitute a fixing member, which is used to fix the child patient to form an actual restraint.

[0046] Preferably, the data acquisition component 2 includes a sensing component 21 and a photographing component 22 .

[0047] The sensing component 21 is electrically connected to the control component 4, and is used to collect relevant signals of the child patient's human body movements in real time. The shooting component 22 is electrically connected to the control component 4, and is used to collect graphic information of the child patient in real time. The data collected by the data acquisition component 2 is used as the starting signal source for the control component 4 to start the driving component 14 to drive the deformable component 13 to deform. Therefore, the sensing component 21 is used in conjunction with the shooting component 22 to synchronously collect signals. In actual use, the sensing component 21 is used for initial data monitoring. When the sensing component 21 senses data changes, the shooting component 22 further confirms whether there is any action through the captured graphic information. Therefore, the cooperation between the sensing component 21 and the shooting component 22 can more accurately determine whether the child patient's lower limbs have any action.

[0048] Preferably, the sensing component 21 includes one or more of a pressure sensor, an angle sensor, and a distance sensor.

[0049] The pressure sensor can be arranged on the bed 3 to monitor the pressure applied by the child patient to the bed. Specifically, a commercially available resistive pressure-sensitive fabric sensor is used. In actual use, the control component 4 is used to monitor the pressure change signal applied by the child patient to the bed to further predict and monitor whether the child patient has any action.

[0050] The angle sensor can be set at the groin of the puncture site of the child patient to monitor the angle between the lower limbs and the waist of the child patient at the puncture site. Specifically, a commercially available flexible joint motion angle optical fiber sensor is used. In actual use, the control component 4 is used to monitor the angle between the lower limbs and the waist of the child patient at the puncture site, which is used as a basis for judging the movement behavior of the lower limbs of the child patient.

[0051] The distance sensor can be set at the groin position and the lower limb position of the puncture site of the child patient to monitor the distance between the groin position and the lower limb position of the puncture site of the child patient and the reference position. Specifically, a commercially available infrared distance sensor is used. In actual use, the distance sensor can be installed on the bed 3, and the foot corresponding to the puncture site of the child patient is used as a reference to monitor the distance from the fixed point of the bed 3 to the foot, which is used as a basis for judging the movement behavior of the child patient's lower limbs.

[0052] In actual use, one or more combinations are used. If multiple combinations are used, the sensor that detects the change is used in conjunction with the camera 22 to determine whether the child patient has made any movement or behavior. Specifically, the sensing component includes a pressure sensor and an angle sensor. When the pressure sensor detects a pressure change, but the angle sensor does not detect a signal change, it may be that the child patient is in the early stage of making a movement or behavior, and the angle between the lower limb and the waist at the puncture site has not changed. In this case, the signal detected by the angle sensor is used as the initial data monitoring of the start signal source, and the graphic information captured by the camera 22 is used to further confirm whether there is any movement or behavior.

[0053] The sensing component of this embodiment includes a pressure sensor and a distance sensor.

[0054] Preferably, Figure 1 , Figure 2 As shown, the mounting member 11 includes a first mounting member 111 and a second mounting member 112. There are two first mounting members 111, which are arranged on the bed 3 at intervals and located on both sides of the middle section of the surface of the bed 3; there are two second mounting members 112, which are arranged on the bed 3 at intervals and located on both sides of the lower section of the surface of the bed 3.

[0055] The limiting member 12 includes a first limiting member 121 and a second limiting member 122. There are two first limiting members 121, which are arranged on two first mounting members 111 in a one-to-one correspondence, and are used to limit the waist of the child patient; the second limiting member 122 is installed on any second mounting member 112, and is used to limit the lower limbs of the child patient at the puncture position.

[0056] The first mounting member 111 and the first limiting member 121 constitute a component for limiting the waist of the child patient, and the second mounting member 112 and the second limiting member 122 constitute a component for limiting the lower limbs of the child patient at the puncture site. The components for limiting the waist and the legs are independently arranged, which can effectively reduce the effective fixing area of ​​the child patient in actual use, and avoid the overall structural components causing large-area fixation of the child patient and causing more serious discomfort. In addition, the two independent components are also more convenient for medical staff to operate in actual use.

[0057] Preferably, Figure 2 As shown, the first mounting member 111 includes a first mounting rod 1111 and a mounting base plate 1112. One end of the first mounting rod 1111 is slidably disposed on the bed body 3, and a first slide groove 301 corresponding to the first mounting rod 1111 is disposed on the bed body 3. The mounting base plate 1112 is rotatably disposed at the other end of the first mounting rod 1111, and the mounting base plate 1112 is an arc-shaped structure; the first stopper 121 is disposed on the mounting base plate 1112.

[0058] In actual use, for children with different body shapes, the actual position of the first mounting rod 1111 can be adaptively adjusted by adjusting the actual position of the first slide slot 301. It should be noted that: in this embodiment, the first mounting rod 1111 is fixed by bolts after sliding to a suitable position in the first slide slot 301. In addition, the first mounting rod 1111 is a telescopic structure, and this embodiment specifically adopts a threaded adjustable telescopic rod.

[0059] Before use, the two mounting base plates 1112 are rotated to positions away from each other, and the child patient lies on the bed 3, and then the two mounting base plates 1112 are reset.

[0060] Preferably, Figure 4 As shown, the first stopper 121 includes an adjustment rod 1211 and a first base 1212. There is at least one adjustment rod 1211, which is threadedly arranged on the mounting base 1112; the adjustment rod 1211 can adjust the length of the side of the mounting base 1112 close to the bed 3 through the thread; the first base 1212 corresponds to the adjustment rod 1211 and is arranged on the adjustment rod 1211, and is located at one end of the adjustment rod 1211 close to the bed 3.

[0061] The gap at the waist is the gap between the mounting base 1112 and the child patient. The width of the gap can be adjusted by adjusting the length of the adjusting rod 1211 located on the side of the mounting base 1112 close to the bed 3 to meet different child patients or different braking requirements, which has a wider range of applicability in actual use.

[0062] Preferably, Figure 4 As shown, the second mounting member 112 includes a base 1121 and a second mounting rod 1122. The base 1121 is slidably arranged on the bed body 3, and a second slide groove 302 corresponding to the base 1121 is arranged on the bed body 3. There are two second mounting rods 1122, and the two second mounting rods 1122 are arranged on the base 1121 at intervals and on both sides of the base 1121; the second limiter 122 is arranged on the second mounting rod 1122. Similarly, by adjusting the actual position of the base 1121 in the second slide groove 302, it can adapt to pediatric patients of different body shapes. In actual use, the base 1121 is adjusted and fixed by bolts after the actual position of the second slide groove 302 is determined. In addition, the second mounting rod 1122 is a telescopic structure, and this embodiment specifically adopts a threaded adjustment telescopic rod.

[0063] Preferably, Figure 4 As shown, the second limiting member 122 includes two limiting plates 1220, which are rotatably arranged on the two second mounting rods 1122 in a one-to-one correspondence, and the two limiting plates 1220 are clamped. Before use, after the two limiting plates 1220 are rotated to positions away from each other, the child patient places the lower limbs on the base 1121 and between the two second mounting rods 1122, and then the two limiting plates 1220 are reset and clamped. The gap at the lower limb part is the gap between the limiting plates 1220 and the child patient, and the width of the gap can be actually adjusted according to different child patients or different braking requirements by adjusting the actual height of the second mounting rods 1122.

[0064] Preferably, Figure 5 As shown, the deformable member 13 includes a mounting disc seat 131 and a capsule 132. There is at least one mounting disc seat 131, which is fixedly arranged on the limit member 12. The capsule 132 corresponds to the mounting disc seat 131 and is sleeved on the mounting disc seat 131; the capsule 132 and the mounting disc seat 131 constitute an inflatable deformation chamber; the driving member 14 is an inflation and deflation device, which is connected to the inflatable deformation chamber and adjusts the actual shape of the inflatable deformation chamber through gas. Among them, the capsule 132 is a flexible deformable material, and rubber is used in this embodiment.

[0065] In actual use, when the driving member 14 inflates the inflatable deformation cavity, the actual shape of the inflatable deformation cavity can be quickly changed, and the bladder 132 also has a certain cushioning property, and will not produce a large impact force on the body surface of the child patient after inflation, thereby having a higher safety. In addition, since the bladder 132 can be deformed under pressure after the inflatable deformation cavity is inflated, it is also more comfortable when fixing the child patient.

[0066] The deformable member 13 adopts an inflatable structure. Since the capsule 132 is made of a flexible material, it has a better comfort level and will not cause serious discomfort to the child patient when in use. In addition, since the inflatable deformable cavity needs to fill the gap more quickly, the inflation and deflation method has the advantage of faster deformation compared to the telescopic deformation of the traditional mechanical structure.

[0067] Preferably, the mounting plate 131 is arranged on the limiting member 12 through an elastic member 133. In this embodiment, the mounting plate 131 is arranged on the first base 1212 and the limiting plate 1220 through an elastic member 133, and the elastic member 133 is specifically a deformable metal mounting sheet. The elastic member 133 improves the buffering performance of the structure, further avoiding unnecessary damage caused by a large impact force on the body surface of the child patient.

[0068] The working method of the above embodiment is:

[0069] Before use, the two mounting base plates 1112 are rotated to positions away from each other, and the two limiting plates 1220 are rotated to positions away from each other, and the child patient lies on the bed body 3. Then, the first mounting rod 1111 is slid to a suitable position in the first slide groove 301 and fixed by bolts, and the adjustment base 1121 is slid to a suitable position in the second slide groove 302 and fixed by bolts, wherein the first mounting rod 1111 is ensured to be level with the child patient's waist, and the adjustment base 1121 is ensured to be close to the child patient's knee joint or calf.

[0070] After adjusting the first mounting rod 1111 to the highest position and the second mounting rod 1122 to the highest position, the mounting base plate 1112 and the limit plate 1220 are reset. By adjusting the actual height of the first mounting rod 1111 and the length of the side of the adjusting rod 1211 close to the bed body 3, the actual width of the gap at the waist is adjusted, and by adjusting the actual height of the second mounting rod 1122, the actual width of the gap at the lower limbs is adjusted.

[0071] During normal use, the inflatable deformable cavity is in a deflated state. At this time, except for the bed body 3, the restraint component 1 does not contact the child patient, so the fixed restraint will not cause discomfort to the child patient. The data acquisition component 2 collects the human body motion data of the child patient in real time. When the control component 4 determines that the child patient's lower limb at the puncture site has a movement behavior, the inflatable deformable cavity is inflated using the inflation and deflation equipment, and the capsule 132 is deformed and contacts the child patient, fixing the child patient to form an actual restraint.

[0072] The data acquisition component 2 continuously collects the human body motion data of the child patient. When the control component 4 determines that the movement of the lower limbs of the child patient at the puncture site has stopped, the inflatable deformation cavity is deflated using the inflation and deflation equipment, and the inflatable deformation cavity returns to a deflated state.

[0073] It should be noted that the adjustment of the actual width of the gap is not only to accommodate children of different body shapes. Since the deformable member 13 is triggered to deform when it detects movement of the lower limbs of the child patient, and it also needs to deform to fill the gap before it can fix and restrain the child patient, therefore, in actual use, the actual width of the gap needs to be kept at a small distance to ensure that the deformable member 13 can quickly fix and restrain the child patient after deformation. Therefore, the width of the gap is best selected as 1cm to 2cm.

[0074] Example 2

[0075] The difference from the first embodiment is that a pressure sensor is provided on the side of the deformable member 13 close to the bed 3 , and the pressure sensor is electrically connected to the control component 4 for monitoring the actual pressure exerted on the body surface of the child patient when the child patient is fixed.

[0076] The pressure sensor at this location monitors the actual pressure on the child patient's body surface, which can avoid excessive impact on the child patient. On the other hand, when the child patient gives up the action, the pressure signal monitored by the pressure sensor at this location will gradually decrease, so it can be used as a basis for judging whether the deformable member 13 is reset.

[0077] The specific models of the above electronic components are not specially specified, and ordinary products available on the market can be selected as long as they can meet the use requirements of the present invention.

[0078] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and does not limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are included in the protection scope of the present invention.
