Description

Technical Field

[0001] The invention relates to the technical field of medical fixing belts, in particular to a comfortable and firm medical fixing belt. Background Art

[0002] In the field of medical care, especially during patient rehabilitation and treatment, various auxiliary devices are often needed to fix treatment objects or specific parts of the patient's body. Traditional fixation methods, such as using tape, bandages or simple straps, often have problems such as loose fixation, easy slipping, and poor comfort. This not only affects the treatment effect, but may also increase the patient's pain and discomfort.

[0003] In the current medical care field, traditional fixation belts still have significant defects in breathability and comfort. First of all, traditional fixation belts often adopt an integral design, and the support surface cannot be adjusted, which leads to a stuffy feeling on the waist skin due to lack of air circulation after long-term wearing, and even causes skin problems such as eczema. In addition, the material of the fixation belt is often not breathable enough, which further aggravates the stuffiness and reduces the patient's wearing experience. In addition, in order to ensure that the medical fixation belt can remain stable enough when worn for a long time, the wearer generally wears it tightly. Traditional fixation belts usually rely on simple straps or Velcro designs for tightness adjustment. Although this adjustment method is simple, it cannot be automatically adjusted according to the patient's breathing and body shape changes, resulting in the patient feeling a sense of restraint on the waist when breathing, affecting the smoothness of breathing. Long-term wearing may also cause unnecessary pressure on the waist, affecting the patient's recovery process and having a great impact on the wearer's wearing comfort. Summary of the invention

[0011] A plurality of movable blocks are arranged on one side surface of the regulating box, a top moving piece fixedly connected to a side surface of the horizontal plate is arranged on one side surface of the movable block, a force bearing groove is arranged on one side surface of the movable block, a connecting plate is arranged on both sides of the force bearing groove, a plurality of return springs are arranged on one side surface of the connecting plate, and the other end of the return spring is fixedly connected to the inner side surface of the regulating box;

[0012] A driving box is fixedly mounted on the upper surface of the regulating box, a telescopic motor is arranged inside the driving box, a motor mounting frame is arranged on the surface of the telescopic motor, the motor mounting frame is fixedly connected to the inner top surface of the driving box, a connecting rod is arranged on the output shaft of the telescopic motor, and a plurality of top piles are sleeved on the surface of the connecting rod.

[0013] Furthermore, a plurality of sliding wheels are arranged on one side surface of the connecting frame, a plurality of connecting springs connected to the inner side surface of the fixing belt body are arranged on both side surfaces of the connecting frame, and sliders are fixedly installed on the top and bottom surfaces of the connecting frame.

[0014] Furthermore, two placement plates are fixedly mounted on one side surface of the movable plate, movable piles are arranged at the centers of the two placement plates, and a ring frame is arranged at the connection point of the two movable piles.

[0015] Furthermore, a fixing frame matched with the movable plate is also provided inside the fixing belt body, a driving motor is provided on the upper surface of the fixing frame, a breathing detector for detecting the breathing frequency of the wearer and controlling the rotation speed of the driving motor through a signal is provided on one side surface of the fixing belt body, a rotatable rotating disk is provided on one side surface of the driving motor, a rotatable sliding pile is provided on one side surface of the rotating disk, and the sliding pile matches with the annular frame.

[0016] Furthermore, a slideway for the sliding wheel to slide is arranged on one side surface of the fixing frame, and a limiting strip matched with the two sliding blocks is also arranged on one side surface of the fixing frame.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In this solution, by providing a support component, the back support plate and the side support plate realize all-round support for the wearer's waist. The multiple ventilation holes on each horizontal plate effectively promote air circulation and significantly reduce the stuffiness that may be caused by long-term wearing. The horizontal plate can dynamically adjust the shape of the support surface with the assistance of the adjustment component. Through the drive of the telescopic motor, the top pile and the force groove cooperate to realize the up and down movement of the horizontal plate, thereby changing the shape of the support surface and the distribution of the ventilation holes, improving the support effect, allowing air to circulate more smoothly, further reducing the wearer's stuffiness, and improving the comfort and health of wearing;

[0019] 2. In this solution, by providing an adjustment component and intelligently driving the telescopic motor, precise control of the support surface shape is achieved. The wearer only needs to operate the switch button to start the small exhaust fan and the telescopic motor, and complete the adjustment of air intake, ventilation and support surface at the same time. The small exhaust fan in the adjustment component and the ejection and reset effects of the multi-layer horizontal plates are combined to form a good air circulation system. The small exhaust fan inhales fresh air from the air inlet, and discharges the heat and moisture around the wearer's waist through the gaps and vents between the ejected and reset horizontal plates, and finally discharges it from the air outlet, thereby reducing the temperature and humidity of the waist skin, reducing the growth of bacteria and mold, and keeping the wearer's waist dry and comfortable;

[0020] 3. In this scheme, by providing an elastic mechanism, real-time monitoring and response to the wearer's breathing frequency is achieved through the respiratory detector, the drive motor and the movable plate, so that the fixing belt body can automatically adjust the contraction and expansion in a small range according to the breathing frequency when the wearer breathes. When the wearer inhales, the respiratory detector transmits the signal generated by the change in breathing frequency to the drive motor, and the drive motor adjusts the speed immediately. Through the coordinated action of the rotating disk and the sliding pile, the movable pile slides in the annular frame, thereby driving the movable plate to expand slightly outward, providing additional space for the wearer's waist and reducing the sense of restraint when breathing. On the contrary, during the exhalation stage, the movable plate automatically resets to keep a close fit with the wearer's waist to ensure the support effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0031] Example 1: Please refer to Figures 1 to 8 , a comfortable and firm medical fixation belt, comprising:

[0032] A fixing belt body 1, a plurality of breathable mesh pads 13 are arranged on the inner side surface of the fixing belt body 1, an elastic pad 17 is arranged on the rear side of the fixing belt body 1, storage bags 2 are arranged on both side surfaces of the fixing belt body 1, a main side strap 3 and a secondary side strap 4 are arranged inside the two storage bags 2, Velcro sub-buttons 5 are arranged on the surfaces of the main side strap 3 and the secondary side strap 4, Velcro female buckles 7 cooperating with the Velcro sub-buttons 5 are also arranged on both side surfaces of the fixing belt body 1, an armpit support frame 8 is arranged on the upper surface of the fixing belt body 1, and two shoulder straps 12 are arranged on the upper surface of the armpit support frame 8;

[0033] When in use, the user wears the fixing belt body 1 around the waist, passes both arms through the two shoulder straps 12 above the fixing belt body 1 to fix the fixing belt body 1 on the body, and pulls the main side straps 3 and the secondary side straps 4. Because the main side straps 3 and the secondary side straps 4 are made of elastic materials, the user pulls the main side straps 3 and the secondary side straps 4 out of the storage bag 2 according to his or her waist circumference, and passes the secondary side straps 4 through the opening at the center of the main side straps 3 to adhere to the Velcro female buckle 7 on one side of the fixing belt body 1, and then adheres the main side straps 3 to the Velcro female buckle 7 on the other side to fix the fixing belt body 1 to complete wearing;

[0034] The above process is the basic process of using medical fixation belts.

[0035] However, in the actual use of the medical fixation belt, since the fixation belt body 1 needs to be worn on the body for a long time, even if the material is made of a good breathable material, the internal ventilation effect will be affected to a certain extent due to the obstruction of the steel plate for supporting the waist, and the steel plate is generally in close contact with the waist of the wearer. Even if there are ventilation holes on the surface of the steel plate, the ventilation efficiency is relatively low;

[0036] In addition, when worn for a long time, the wearer generally tightens the fixing belt body 1 to prevent it from falling off. However, too close contact between the fixing belt body 1 and the body will cause the wearer to feel that breathing is restricted, causing the wearer to feel more uncomfortable.

[0037] Therefore, based on the above problem, we first designed a ventilation mechanism, which is composed of a support component and an adjustment component. The support component includes: a back support plate 15 and multiple side support plates 16. The back support plate 15 and the side support plates 16 are composed of multiple horizontal plates arranged vertically. The surface of each horizontal plate is provided with multiple ventilation holes 19. The multiple horizontal plates that constitute the back support plate 15 and the side support plates 16 can move independently. The side surface of the fixed belt body 1 is also provided with an air inlet 10 for taking air into the interior of the fixed belt body 1 and an air outlet 11 for exhausting air. A small exhaust fan is arranged inside the air inlet 10. The side surface of the fixed belt body 1 is also provided with a switch button 14 for controlling the small exhaust fan.

[0038] When the wearer wears the fixing belt body 1 around the waist, multiple ventilation holes 19 can allow air to flow freely around the wearer's waist to reduce the feeling of stuffiness. The horizontal plate can be moved independently to adjust the support surface under the adjustment component to prevent the waist contact surface from being in contact for too long and causing stuffiness. It also reduces the obstruction of the steel plate to the wearer's waist contact surface, improves the ventilation efficiency, and maintains sufficient support force.

[0039] The adjustment component includes: a plurality of adjustment boxes 18, the plurality of adjustment boxes 18 are located inside the fixed belt body 1, and one side surface of the back support plate 15 and each side support plate 16 is provided with an adjustment box 18, one side surface of the adjustment box 18 is provided with a plurality of movable movable blocks 22, one side surface of the movable block 22 is provided with a top moving plate 25 fixedly connected to one side surface of the cross plate, one side surface of the movable block 22 is also provided with a force groove 26, both side surfaces of the force groove 26 are provided with a connecting plate 27, one side surface of the connecting plate 27 is provided with a plurality of return springs 28, the other end of the return spring 28 is fixedly connected to the inner side surface of the adjustment box 18, the upper surface of the adjustment box 18 is fixedly installed with a driving box, a telescopic motor 20 is provided inside the driving box, a motor mounting frame 21 is provided on the surface of the telescopic motor 20, the motor mounting frame 21 is fixedly connected to the inner top surface of the driving box, a connecting rod 23 is provided on the output shaft of the telescopic motor 20, and a plurality of top piles 24 are provided on the surface of the connecting rod 23;

[0040] When the fixing belt body 1 is being worn, the wearer presses the switch button 14, and the switch button 14 drives the telescopic motor 20 to work. The small exhaust fan arranged inside the air inlet 10 starts to suck air. At the same time, the telescopic motor 20 on the upper surface of each adjustment box 18 starts, driving the connecting rod 23 to move up and down to a certain extent. At this time, the top pile 24 will move up and down synchronously, and the movable block 22 and the cross plate will be pushed out by cooperating with the force groove 26 to realize the movement of the cross plate. Every two cross plates cooperate with a top pile 24, and the cross plate above When being pushed out, the lower horizontal plate returns to its original position through the restoring effect of the restoring spring 28 on the side of the movable block 22, thereby realizing the interchange of the ejection and restoring effects of the multi-layer horizontal plates. The wind sucked in by the small exhaust fan passes through the side gaps of the pushed out and reset horizontal plates, and reduces the heat on the wearer's skin surface through the vents 19, and is discharged from the air outlet 11 on the other side of the fixing belt body 1, forming convection with the air inlet 10, discharging internal heat and moisture, keeping the wearer's waist dry and comfortable, thereby achieving the effect of improving wearing comfort.

[0041] At the same time, based on the previous problems, we have also designed an elastic mechanism, which includes: two movable plates 6, the two movable plates 6 are respectively located on the two side surfaces of the fixed belt body 1, a connecting frame 32 is provided on one side surface of the movable plate 6, a plurality of sliding wheels 33 are provided on one side surface of the connecting frame 32, a plurality of connecting springs 34 connected to the inner side surface of the fixed belt body 1 are provided on both side surfaces of the connecting frame 32, a slider 35 is fixedly installed on the top and bottom surfaces of the connecting frame 32, two placement plates 29 are also fixedly installed on one side surface of the movable plate 6, a movable active pile 30 is provided at the center of the two placement plates 29, and a movable pile 30 is provided at the connection between the two movable piles 30. The annular frame 31, the interior of the fixed belt body 1 is also provided with a fixed frame 36 matched with the movable plate 6, the upper surface of the fixed frame 36 is provided with a driving motor 37, and the side surface of the fixed belt body 1 is provided with a breathing detector 9 for detecting the breathing frequency of the wearer and controlling the rotation speed of the driving motor 37 through a signal, and the side surface of the driving motor 37 is provided with a rotatable rotating disk 38, and the side surface of the rotating disk 38 is provided with a rotatable sliding pile 39, and the sliding pile 39 cooperates with the annular frame 31, and the side surface of the fixed frame 36 is provided with a slideway 40 for the sliding wheel 33 to slide, and the side surface of the fixed frame 36 is also provided with a limiting strip 41 matched with the two sliders 35;

[0042] When the wearer fixes the main side strap 3 and the secondary side strap 4 on the surfaces of the Velcro female buckles 7 on both sides, the breathing detector 9 on the surface of the fixing belt body 1 monitors the wearer's breathing frequency in real time and transmits the signal to the driving motor 37. The driving motor 37 adjusts the speed according to the breathing frequency, rotates through the rotating disk 38 and the sliding pile 39, and makes the sliding pile 39 slide inside the annular frame 31, so that the movable pile 30 slides back and forth, and drives the movable plate 6 to slide back and forth synchronously. When sliding, the sliding wheel 33 on the side surface of the connecting frame 32 slides inside the slideway 40, and the sliding effect is more stable through the cooperation of the limiting strip 41 and the slider 35, so that the fixing belt body 1 can automatically achieve a small range of contraction and expansion in accordance with the frequency of the breathing when the wearer breathes, so that the fixing belt body 1 always maintains a stable fit with the wearer's waist, and will not be restricted by the waist when the wearer breathes, ensuring that the wearer does not feel uncomfortable when breathing.

[0043] The working principle of the present invention is:

[0044] When in use, the user wears the fixing belt body 1 around the waist, passes both arms through the two shoulder straps 12 above the fixing belt body 1 to fix the fixing belt body 1 on the body, and pulls the main side straps 3 and the secondary side straps 4. Because the main side straps 3 and the secondary side straps 4 are made of elastic materials, the user pulls the main side straps 3 and the secondary side straps 4 out of the storage bag 2 according to his or her waist circumference, and passes the secondary side straps 4 through the opening at the center of the main side straps 3 to adhere to the Velcro female buckle 7 on one side of the fixing belt body 1, and then adheres the main side straps 3 to the Velcro female buckle 7 on the other side to fix the fixing belt body 1 to complete wearing;

[0045] After the wearer fixes the main side strap 3 and the secondary side strap 4 on the surface of the Velcro female buckle 7 on both sides, the respiratory detector 9 on the surface of the fixing belt body 1 monitors the wearer's breathing frequency in real time and transmits the signal to the driving motor 37. The driving motor 37 adjusts the speed according to the breathing frequency, so that the fixing belt body 1 can automatically achieve a small range of contraction and expansion in accordance with the breathing frequency of the wearer when breathing, so that the fixing belt body 1 always maintains a stable fit with the wearer's waist, and the wearer will not be restricted by the waist when breathing, ensuring that the wearer will not feel uncomfortable when breathing;

[0046] When the fixing belt body 1 is being worn, the wearer presses the switch button 14 to drive the telescopic motor 20 to work, and the small exhaust fan arranged inside the air inlet 10 starts to suck air. At the same time, the telescopic motor 20 on the upper surface of each adjusting box 18 starts, driving the connecting rod 23 to move up and down to a certain extent, so as to realize the movement of the cross plate. Every two cross plates cooperate with a push pile 24. When the upper cross plate is pushed out, the lower cross plate returns to its original position through the reset effect of the reset spring 28 on the side of the movable block 22, thereby realizing the interchange of the ejection and reset effects of the multi-layer cross plates. The wind sucked in by the small exhaust fan passes through the side gaps of the pushed out and reset cross plates, and reduces the heat on the skin surface of the wearer through the vent 19, and is discharged from the air outlet 11 on the other side of the fixing belt body 1, forming convection with the air inlet 10, and discharging the internal heat and moisture, keeping the wearer's waist dry and comfortable, thereby achieving the effect of improving the wearing comfort.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
