Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a turning-over auxiliary device which is easy to wear. Background Art

[0002] Parkinson's disease is a degenerative disease of the nervous system whose main clinical features are motor symptoms such as resting tremor, muscle rigidity, bradykinesia, postural balance disorders, and non-motor symptoms such as hyposmia, constipation, abnormal sleep behavior, and depression.

[0003] Parkinson's patients may suffer from muscle aches all over the body if they maintain the same posture at night, which is very painful for the patients and may make them feel frustrated, helpless and lonely. On the other hand, it is easy to cause skin problems such as pressure sores. Therefore, an easy-to-wear auxiliary turning device is needed.

[0004] The Chinese utility model patent with the announcement number "CN215915370U" discloses "a turning buckle for hospital nursing". This utility model patent mainly uses a strap structure design to facilitate patients to wear and use, wherein the strap is placed on the bed surface and cushioned under the patient's back. When turning the patient over, the sleeves and straps are quickly assembled so that the whole can be worn on the patient, and then the medical staff can turn the patient over by buckling. After turning over, the airbag on the back side of the strap can be inflated by a pressurized airbag to form a support part to assist in supporting the side-lying patient. In summary, the utility model is easy to use through the wearable strap structure design, and after wearing, force can be applied through the buckle to facilitate turning the patient over. In addition, an airbag that can be manually inflated to support the patient is also provided. The overall structural setting is simple and reasonable, and the practicality is good.

[0005] However, Parkinson's patients have limited mobility, so traditional devices are not convenient to wear, which reduces the practicality of the wearable device. At the same time, when turning over, the upper body of the nursing vest is squeezed against the bed surface. If the design here is not good, it is easy to affect comfort and the wearable device is easy to loosen due to squeezing when turning over. Utility Model Content

[0006] This application is made in view of the above-mentioned state of the prior art. The purpose of this application is to provide a turning-over assisting device that is easy to wear.

[0007] The technical solution adopted by the present application to solve its technical problems is: a wearable vest, comprising two vest pieces for covering the front chest and back of the wearer respectively, and the two vest pieces are connected by shoulder straps; a connecting ring, fixed to the side of the vest piece; a connecting rope, passing through the connecting ring and turning, and the trajectory of the connecting rope itself forms a U shape; a winding device, one end of the connecting rope is connected to the wearable vest, and the other end of the connecting rope is connected to the winding device, and the winding device reduces the distance between the two vest pieces by winding and shortening the length of the connecting rope.

[0008] As a further improvement of the present application, the connecting ring and the winding device are located on different vest pieces; each connecting rope passes through at least two connecting rings, and the same side of the two vest pieces in the left and right directions is also connected by at least two connecting ropes.

[0009] As a further improvement of the present application, the connecting ring is made of rubber.

[0010] As a further improvement of the present application, the winding device is buried inside the vest piece; one end of the connecting rope is detachably connected to the vest piece.

[0011] As a further improvement of the present application, the winding device includes a power chamber arranged inside the vest piece, a rotating motor is fixed to the inner wall of the power chamber, an output end of the rotating motor is connected to a driving worm gear, the driving worm gear is connected to a first rotating shaft and a second rotating shaft in sequence, the first rotating shaft and the second rotating shaft are arranged parallel to each other, the first rotating shaft and the driving worm gear are arranged perpendicular to each other, and a portion of the connecting rope is wound around the second rotating shaft.

[0012] As a further improvement of the present application, a first gear and a driven worm wheel are coaxially fixed to the first rotating shaft, a second gear is coaxially fixed to the second rotating shaft, the first gear and the second gear are meshed with each other, and the driven worm wheel and the driving worm are meshed with each other.

[0013] As a further improvement of the present application, an inner support block is provided inside the vest piece, the power cavity is located inside the inner support block, the inner support block is wrapped with an arc-shaped rubber block, and the power cavity has a connecting port for the connecting rope to enter and exit.

[0014] As a further improvement of the present application, the outer wall of the vest piece for covering the back of the wearer is provided with two inflatable bags, and the two inflatable bags are arranged in mirror symmetry on both sides of the vertical center line of the worn vest.

[0015] As a further improvement of the present application, the inflation bulge and exhaust depression of the two inflatable bags on both sides of the vertical center line of the wearing vest can be controlled independently of each other.

[0016] As a further improvement of the present application, the turning over assist device also includes a control box, and the two inflatable bags are each connected to the same control box through an independent connecting hose. An air pump is provided in the control box, and the air pump is connected to the two connecting hoses through a two-way connector.

[0017] This technical solution provides a nursing vest for Parkinson's patients, for example, with adjustable overall tightness. Because the connecting rope is firmly tied to the connecting ring at the turning point, there is a tightening force, and the more the connecting rope is pulled, the more firmly it is connected to the connecting ring. Therefore, compared with traditional Velcro, the adjustment part of the vest of this application is not easy to break when the wearer turns over. Because the connecting rope itself is often softer and thinner, and the volume of the connecting ring itself can also be made smaller, compared with the hard plate structure that may exist in the prior art, this application is not easy to hurt the patient.

[0018] First of all, the design of this wearable vest is connected only by shoulder straps, which leaves room for the patient's upper body on both sides. The two vest pieces can be opened at any angle, making it convenient to wear.

[0019] Secondly, the space for wearing the vest is narrowed by tightening the connecting rope so as to accommodate patients of different body shapes.

[0020] Thirdly, compared with similar mechanisms, the connecting rope can be designed to be relatively thin and soft, and the volume of the connecting ring that only needs to be passed through the connecting rope is also relatively small, so as a tension adjustment device, its volume and hardness are better than the existing design, and the final upper body effect is very docile. Therefore, when the patient turns over while lying on his side, the adverse effects of the connecting rope and connecting ring under the body on the patient can be ignored. The connecting rope and connecting ring are also not easy to loosen due to squeezing.

[0021] Finally, the connecting rope is shortened by winding one end, and the overall shape is relatively neat, with no exposed thread ends. At the same time, the connecting ring also plays a similar role as a pulley to change the trajectory of the connecting rope. The U-shaped trajectory of the connecting rope can provide greater tightening force. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The content of the utility model is further described in detail below in conjunction with specific embodiments.

[0032] like Figures 1 to 6 As shown, an embodiment of the utility model of an easy-to-wear turning over assisting device may include a wearing vest 1, a connecting ring 2, a connecting rope 13 and a winding device. The wearing vest 1 has two vest pieces, and the two vest pieces are used to cover the front chest and the back of the wearer respectively, and the two vest pieces are connected by a shoulder strap 23. The connecting ring 2 is fixed to the side of the vest piece. The connecting rope 13 passes through the connecting ring 2 and turns, so that the trajectory of the connecting rope 13 itself forms a U shape. One end of the connecting rope 13 is connected to the wearing vest 1, and the other end of the connecting rope 13 is connected to the winding device, which reduces the distance between the two vest pieces by winding and shortening the length of the connecting rope 13.

[0033] In addition, if Figure 1 As shown, the vest 1 is connected to a control box 14. Figure 2 , Figure 5 As shown, connecting rings 2 can be fixed on the left and right sides of the front piece 21 of the two vest pieces of the vest 1, and four connecting rings 2 can be fixed on each of the left and right sides of the vest 1, and the connecting rings 2 and the winding device are located on different vest pieces; each connecting rope 13 passes through two connecting rings 2, and the same side of the two vest pieces in the left and right directions is also connected by two connecting ropes 13.

[0034] The beneficial effect of adopting the above technical solution is that two connecting rings 2 can shape a connecting rope 13 into a U shape, which is equivalent to that the connecting rope 13 makes a right-angle turn each time it passes through a connecting ring 2, so the friction resistance caused by the connecting ring 2 to the connecting rope 13 is relatively small. If there is only one connecting ring 2, the turning of the connecting rope 13 is 180°, which will cause the local deformation of the connecting rope 13 to be too large, and the resistance encountered when pulling will also be relatively large.

[0035] The vest 1 is also fixedly connected with an inner support block 3, and an inner support block 3 can be set on the left and right sides of the back piece 22 of the two vest pieces. A winding device is set on the upper and lower sides of the two inner support blocks 3. The winding device includes a power chamber 4 arranged on the upper and lower sides of the inner support block 3, the inner wall of the power chamber 4 is fixedly connected with a rotating motor 5, and the output end of the rotating motor 5 is connected with a driving worm 6, the driving worm 6 is meshed with a driven worm gear 7, the inner wall of the driven worm gear 7 is fixedly connected with a first rotating shaft 8, the rod wall of the first rotating shaft 8 is fixedly connected with a first gear 9, the top surface of the first gear 9 is meshed with a second gear 10, and the inner wall of the second gear 10 is fixedly connected with a second rotating shaft 20. The first rotating shaft 8 and the second rotating shaft 20 are arranged parallel to each other, the first rotating shaft 8 and the driving worm 6 are arranged perpendicular to each other, and a part of the connecting rope 13 is wound around the second rotating shaft 20. In addition, one end of the connecting rope 13 is detachably connected to the vest piece, and preferably the connecting rope 13 is detachably connected to the back piece 22, which further facilitates putting on and taking off because more space on the chest side can be left.

[0036] The beneficial effect of adopting the above technical solution is that the winding device is located inside, which is also to ensure that the surface of the worn vest 1 is flat and smooth.

[0037] The rotating motor 5 is used to drive the shortening of the connecting rope 13. The driven turbine 7 and the active worm 6 can achieve a force-increasing effect, and even a rotating motor 5 with a relatively small power can achieve tightening. The effect of fast tightening can also be achieved, and the overall transmission structure is relatively stable.

[0038] like Figure 2 As shown, the surfaces of the two inner support blocks 3 are provided with arc-shaped rubber blocks 11, the inner walls of the multiple power chambers 4 and the corresponding surfaces of the arc-shaped rubber blocks 11 are jointly provided with connecting ports 12, and the rod walls of the multiple second rotating shafts 20 are fixedly connected with connecting ropes 13, which can effectively avoid the problem of traditional auxiliary wearing devices being unchanged when worn. The device can achieve a rapid tightening effect through a special structure, and can avoid the problem of loosening of the vest caused by Parkinson's patients turning over, thereby improving the practicability of wearing the vest, reducing the wearing time, and increasing the use effect of the wearing device.

[0039] The beneficial effect of adopting the above technical solution is that the hardness of the inner support block 3 can be greater than that of the outer arc-shaped rubber block 11, and it plays the role of an inner support frame, providing a stable shape and size space for the power chamber 4. The arc-shaped rubber block 11 can adapt to the curvature of the human body.

[0040] like Figure 2 and Figure 3 As shown, the front end of the active worm 6 is rotationally connected with the inner wall of the corresponding power chamber 4, ensuring the normal transmission of power. The two ends of the first rotating shaft 8 and the two ends of the second rotating shaft 20 are rotationally connected with the two sides of the inner wall of the corresponding power chamber 4, that is, the spatial positions of the active worm 6, the driven turbine 7, the first gear 9, and the second gear 10 are relatively fixed in the power chamber 4, but each has the freedom of rotation around its own axis. The normal operation of the winding work is guaranteed. One end of the multiple connecting ropes 13 passes through the inner wall of the corresponding connecting ring 2 and is fixedly connected to one side of the surface of the vest 1, ensuring the normal operation of the device. The connection relationship is used to ensure the stability of the connection of the internal parts of the equipment and reduce the failure rate.

[0041] The beneficial effect of adopting the above technical solution is: such a design is to prevent the wound connecting rope 13 from being too close to the driven turbine 7 and the active worm 6, so as to prevent the connecting rope 13 inside the winding device from being knotted or stuck during long-term use.

[0042] like Figure 1 , Figure 4 As shown, the inner wall of the control box 14 is fixedly connected with an air pump 15, and the upper side of the inner wall of the control box 14 is provided with a plurality of air holes 16, which ensure the normal operation of the air pump 15, and the output end of the air pump 15 is fixedly connected with a two-way joint 17, one end of the two-way joint 17 penetrates the inner wall of the control box 14 and extends to the control box 14, and both ends of the two-way joint 17 are provided with a connecting hose 18, and the connecting hose 18 and the two-way joint 17 can be connected by a tight hoop. The two-way joint 17 can be disassembled to facilitate the patient to wear. Two inflatable bags 19 are provided at the back of the vest 1, and one end of the two connecting hoses 18 is fixedly connected to one side of the corresponding inflatable bag 19, and the actual material of the connecting ring 2 can be rubber material, which is from another perspective, that is, the material selection perspective, to prevent the patient from being hurt and ensure the patient's comfort. Using the air pump 15 to transmit the gas to the corresponding inflatable bag 19 through the connecting hose 18 can make the inflatable bag 19 bulge, which serves the purpose of supporting Parkinson's patients. It is convenient for Parkinson's patients to turn over or move positions, and the practicability of the device is ensured by using a connecting ring 2 made of rubber.

[0043] In actual use, the power drive devices of the device are connected to the external power supply through the line; first, the wearable vest 1 is put on the Parkinson's patient, and then the corresponding active worm 6 is driven to rotate by starting the rotating motor 5 in the power chamber 4, and the meshing action of the active worm 6 and the driven worm gear 7 is utilized to allow the driven worm gear 7 to drive the first rotating shaft 8 to rotate, and then the meshing action of the first gear 9 and the second gear 10 on the first rotating shaft 8 is utilized to allow the second gear 10 to drive the second rotating shaft 20 to rotate, so that the connecting rope 13 can be rolled up, and the appropriate tightness can also be adjusted according to the body shape of the Parkinson's patient to ensure the comfort of the Parkinson's patient.

[0044] When the Parkinson's patient needs to turn over or adjust the body position, the air pump 15 in the control box 14 is used to adjust the height of the left or right side of the Parkinson's patient through the corresponding connecting hose 18 to achieve the purpose of turning over or adjusting the position, thereby completing the entire operation of the device.

[0045] In order to clearly demonstrate the application principle of this device, Figure 5 , Figure 6 These are schematic diagrams of the wearer wearing the turning assist device. Figure 5 The personnel in the room are lying flat. Figure 6 The people in the vehicle are in the process of rolling over.

[0046] Figure 5 It is also a side view, where Figure 5 There is also a partial cross-sectional view showing the active worm 6, the first gear 9, and the second gear 10 hidden inside the wearable vest 1.

[0047] In another embodiment, if Figure 5 As shown, the two connecting rings 2 through which the same connecting rope 13 passes are axially perpendicular to each other. The U-shaped trajectory of the connecting rope 13 itself can also be regarded as three rope segments that are vertically connected in sequence.

[0048] In another embodiment, the material of the connecting ring 2 can also be a soft material such as silicone with properties close to those of rubber. The main function of the connecting ring 2 is to change the direction of the connecting rope 13. As long as the connecting ring 2 has the function of hooking the connecting rope 13, the connecting ring 2 is not limited to the traditional closed loop form. In another embodiment, the vest piece is composed of a front piece 21 and a back piece 22. The front piece 21 is located in front of the chest and the back piece 22 is located on the back. The front piece 21 and the back piece 22 have the same contour. The front piece 21 and the back piece 22 are connected by two shoulder straps 23, and the wearer's head and neck pass between the two shoulder straps 23. Figure 1 As shown, the front piece 21, the back piece 22 and the shoulder strap 23 are connected by an integral material.

[0049] In another embodiment, the connecting ring 2 and the vest piece may be detachably connected, and specific connection methods include but are not limited to threaded assembly and snap-on assembly.

[0050] In another embodiment, a damper may be provided between the rotating motor 5 and the connecting rope 13 to reduce the vibration and inertia force when the rotating motor 5 winds the connecting rope 13. Alternatively, the rotating motor 5 may have the ability to stop when encountering resistance. When the rotating motor 5 winds the connecting rope 13 into place, the resistance will increase when continuing to wind it, causing the current inside the circuit of the rotating motor 5 to increase instantly. The rotating motor 5 is provided with an overcurrent protection device. When the current exceeds the limit value, the internal circuit of the rotating motor 5 will be disconnected from the power supply, causing the rotating motor 5 to stop working immediately. This improves the patient's comfort, avoids over-tightening the patient, and protects the patient and the rotating motor 5. In addition, the stopping when encountering resistance can be achieved through appropriate sensors and controllers.

[0051] In another embodiment, if Figure 3 As shown, the diameter of the driven worm gear 7 is smaller than the diameter of the first gear 9 .

[0052] Optionally, the inflation bulge and exhaust depression of the two inflatable bags 19 on both sides of the vertical centerline of the wearing vest 1 can be controlled independently of each other or in association. In the independently controlled solution, two air pumps can be used. The inflatable bags 19, i.e., air bags, can play a role in dynamically lifting the patient. Figure 6 This is a perspective from the top of the wearer's head to the feet, and in order to facilitate the demonstration of how to use the inflatable bag 19 to assist in turning over, Figure 6 One of the two inflatable bags 19 is relatively deflated, while the other is inflated, so as to support the wearer who is originally lying flat to turn over and tilt to one side.

[0053] The beneficial effect of adopting the above technical solution is that the patient can be lifted or turned over to the left or right according to the needs. When the air pump 15 inflates the air bag 19, the air bag 19 will increase in size and be lifted, so that the personnel can independently control the turning direction of the patient. Because the control box 14 is convenient and portable, the patient can also use the control box 14 to help himself turn over.

[0054] In another embodiment, if Figure 4 As shown, the outline of each inflatable bag 19 is in the shape of a waist-shaped hole.

[0055] It can be understood that the device of the present invention is not limited to being worn by Parkinson's patients, but can also be used by other people with limited mobility.

[0056] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology in this field to understand the content of the utility model and implement it. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
