Description

Technical Field

[0001] The present invention relates to the field of medical care devices, and more specifically, to an orthopedic care auxiliary fixing device. Background Art

[0002] Orthopedic care auxiliary fixation refers to using various methods and instruments to fix the fractured part or injured joint of a patient during orthopedic care to promote fracture healing, relieve pain, prevent joint dislocation or deformity, etc. Common auxiliary fixation instruments include splints, which are fixed on the injured limb by bandages or other fixing devices to limit the limb, and plaster bandages made of calcined gypsum powder and gauze, etc. When the plaster bandage is soaked in water, the calcined gypsum undergoes a hydration reaction and gradually hardens, so that it can be shaped according to the shape of the limb.

[0003] For patients with upper limb arm injuries, especially the upper arm, such as the humerus, when fixing, in order to promote the blood return of the arm to the heart, relieve the swelling of the limb end caused by the fracture, and avoid the fracture displacement caused by the movement of the affected limb or muscle traction, usually the affected limb is suspended by a strap or a triangular bandage, etc. Suspending the affected limb on the neck or shoulder can keep the arm stable to a certain extent for the patient, and at the same time facilitate the patient to carry out other daily activities. However, hanging the upper limb on the neck by a strap, etc. for a long time will change the body center of gravity. In order to balance the weight of the upper limb, the spine, especially the cervical and thoracic vertebrae parts, will be forced to be in an unnatural posture, which may cause the physiological curvature of the spine to change, such as increased lordosis of the cervical vertebra or kyphosis of the thoracic vertebra, thus causing spinal muscle strain and long-term spinal deformity. One shoulder bears the weight of the upper limb for a long time, and the muscles are in a tense state for a long time, while the other shoulder is relatively relaxed. This imbalance may lead to an imbalance in the muscle strength of the shoulders, resulting in the overdevelopment of muscles such as the trapezius muscle and deltoid muscle on one side and atrophy on the other side, and then causing problems such as shoulder pain and limited movement. Moreover, fractures are often accompanied by injuries to the surrounding soft tissues, including muscles, tendons, blood vessels and nerves. The inflammatory reaction of these soft tissues will cause local congestion, edema, or the local blood circulation may be affected, resulting in poor blood and lymph fluid return, and then causing swelling. However, through the current splints or plasters, etc., after being fixed on the limb, they are fixed. The swollen limb will be compressed in the fixed splint, resulting in increased pain, and the splint being too tight will compress the limb, resulting in blocked blood circulation and being unfavorable for the recovery of the affected limb. Summary of the Invention

[0004] Aiming at the problem that the long-term suspension of the affected limb in the prior art affects the comfort of the cervical vertebra and is unfavorable for recovery when the affected limb is swollen, the purpose of the present invention is to provide an orthopedic care auxiliary fixing device.

[0005] To solve the above problems, the present invention adopts the following technical solutions:

[0006] An orthopedic nursing auxiliary fixation device includes a support member for supporting an affected limb, and a waist ring worn around the waist, wherein the outer wall of the waist ring is formed with a sliding track, a moving member is slidably connected to the sliding track, the upper end of the moving member is connected to a support member, and the end of the support member away from the moving member is detachably connected to the support member via a connecting member;

[0007] A binding belt is fixedly connected to one side of the upper end of the supporting member, and a movable end of the binding belt is detachably connected to a side of the supporting member away from the fixed end of the binding belt via a mounting member. When the movable end of the binding belt is connected to the supporting member, the patient positioned on the supporting member can be bound. The binding belt is provided with an adaptive unit that can adjust the tightness according to the degree of swelling of the affected limb. The adaptive unit includes a plurality of air bags mounted on the inner wall of the binding belt, a micro air pump for inflating the air bags, a pressure sensor provided on a side of the air bags away from the binding belt, and a central control unit provided on the movable member and electrically connected to the pressure sensor, wherein the central control unit is used to control the filling degree of the air bags according to the pressure signal of the pressure sensor.

[0008] The waist ring is composed of a plurality of arc-shaped connecting parts, and two adjacent arc-shaped connecting parts are detachably connected to each other, so as to adjust the diameter of the waist ring to adapt to patients with different waist circumferences.

[0009] Optionally, the two sides of the arc-shaped connection part are respectively connected to a plug-in connector and a socket part that cooperates with the plug-in connector, and the plug-in connector is connected to a plug-in connector, a positioning button is threadedly connected to the plug-in connector, and a positioning groove corresponding to the positioning button is provided on the socket part. When the plug-in connector is inserted into the socket part on the adjacent arc-shaped connection part, the positioning button is rotated to move into the positioning groove, and the two adjacent arc-shaped connection parts are connected.

[0010] Optionally, both side walls of the arc-shaped connecting portion are connected with axle pins via a mounting bracket, and the plug-in component and the receiving component are movably connected to the arc-shaped connecting portion via the axle pins.

[0011] Optionally, the support member includes a vertical rod provided on the movable member, an adjusting rod threadedly connected to the top of the vertical rod, and a receiving rod rotatably connected to one end of the adjusting rod away from the vertical rod, and the length of the support member is adjusted by rotating the adjusting rod.

[0012] Optionally, the connecting member includes a support platform threadedly connected to one end of the supporting rod away from the adjusting rod, the support platform is slidingly connected to the bottom of the supporting member through a dovetail groove, and fasteners are threadedly connected to both ends of the support platform, and one end of the fastener extends to the inside of the dovetail groove to lock the supporting member on the support platform.

[0013] Optionally, the two adjacent air bags are connected by a branch air tube, and an electronically controlled valve electrically connected to the central control unit is provided on the branch air tube. The output end of the micro air pump is provided with a main air tube, and the main air tube is respectively connected to a plurality of branch air tubes for inflating and deflating a single air bag.

[0014] Optionally, the central control unit further includes a data processing module and a first data storage module electrically connected to the pressure sensor, which are used to receive the pressure data collected by the pressure sensor, record and store the pressure value detected by the pressure sensor as a standard reference value during the initial use, and set a pressure threshold range according to the standard reference value.

[0015] Optionally, a first warning module is electrically connected to the central control unit. When the central control unit receives that the pressure data monitored by the pressure sensor is not within the set threshold stored in the first data storage module, it controls the first warning module to issue a prompt.

[0016] Optionally, a structural parameter detection unit and a second data storage module are provided on the waist ring. The structural parameter detection unit includes a permanent magnet provided on the side wall of the plug-in part and a Hall element provided on the inner wall of the receiving part. When two adjacent arc-shaped connecting parts are connected, the change in the magnetic field will cause the Hall element to generate a voltage change for detecting the number of arc-shaped connecting parts.

[0017] Optionally, a data comparison and analysis module and a second warning module are further included. The data comparison and analysis module is used to analyze the initial pressure data stored in the first data storage module and the initial quantity data stored in the second data storage module. When it is judged that one of them is not within the initial data, the second warning module issues a warning.

[0018] The technical solution provided by the present invention has at least the following beneficial effects compared with the prior art:

[0019] In the above solution, the affected limb on the supporting member is supported by the waist ring worn on the waist and the supporting member, so that the weight of the arm is effectively dispersed to the waist, reducing the pressure on the neck when the affected limb is suspended. Through the sliding action of the waist ring supporting the arm on the sliding track of the waist ring by the moving member, the arm is relatively independent of the neck, and the patient can adjust the body posture more naturally, and can also swing while the arm is being supported, and the suspension strap will not cause discomfort to the neck when swinging.

[0020] By setting up a pressure sensor in the adaptive unit to monitor the restraining pressure of the binding strap on the affected limb, the airbag is inflated and deflated, so that the binding force can be adjusted in real time and accurately according to the changes in the degree of swelling of the arm. When the swelling gradually increases, the airbag can be deflated to avoid the binding strap being too tight and causing pressure on the swollen area, thereby reducing the patient's pain and discomfort; as the swelling gradually subsides, the airbag can be appropriately inflated to keep the binding strap effectively fixed to the arm. Through dynamic adjustment, the affected limb is always in a more comfortable fixed state, which is conducive to recovery.

[0021] By setting up the first data storage module and the second data storage module, when used on different patients, the binding force of the binding belt and the size of the waist ring suitable for the patient can be recorded in a targeted manner. When the binding belt is used on another patient, when the data comparison and analysis module analyzes that one of the two data is not within the initial data, a prompt can be issued through the second warning module to facilitate the user to appropriately adjust the pressure data of the binding belt and the size of the waist ring according to their own situation, so as to improve the use effect.

[0047] As Figures 1 to 11 shown, an orthopedic care auxiliary fixing device provided by an embodiment of the present invention includes a supporting member 1 for supporting the affected limb. The supporting member 1 can have a structure with an arc-shaped cross-section, so that when the affected limb is placed in the supporting member 1, it is in a semi-wrapped state with respect to the affected limb. It further includes a waist ring 2 worn around the waist, and a sliding track 21 is formed on the outer wall of the waist ring 2. A moving member 22 is slidably connected to the sliding track 21. The upper end of the moving member 22 is connected to a supporting member 3. The end of the supporting member 3 away from the moving member 22 is detachably connected to the supporting member 1 through a connecting member. The upper end of the supporting member 1.

[0048] One side of the upper end of the supporting member 1 is fixedly connected with a binding strap 11. The movable end of the binding strap 11 and the side of the supporting member 1 away from the fixed end of the binding strap 11 are detachably connected through a mounting member 12. And when the movable end of the binding strap 11 is connected to the supporting member 1, the patient on the supporting member 1 can be bound. An adaptive unit for adjusting the tightness according to the swelling degree of the affected limb is provided on the binding strap 11. The adaptive unit includes a plurality of air bags 101 installed on the inner wall of the binding strap 11, a micro air pump 102 for inflating the air bags 101, a pressure sensor 103 provided on the side of the air bag 101 away from the binding strap 11, and a central control unit 4 provided on the moving member 22 and electrically connected to the pressure sensor 103. The central control unit 4 is used to control the filling degree of the air bag 101 according to the pressure signal of the pressure sensor 103.

[0049] The waist ring 2 is composed of a plurality of arc-shaped connecting parts 23, and two adjacent arc-shaped connecting parts 23 are detachably connected to adjust the diameter of the waist ring 2 to adapt to patients with different waist circumferences.

[0050] According to the different waist circumferences of the patients, select an appropriate number of arc-shaped connecting parts 23 to form a waist ring 2 of an appropriate size. The best state of the size of the waist ring 2 is that it can be stuck on the waist and will not fall down. Then place the affected upper limb on the supporting member 1, and the affected limb on the supporting member 1 can be supported through the waist ring 2 and the supporting member 3. The waist of the human body is relatively stronger to bear additional loads. When the arm is injured, it is difficult to bear its own weight. By using the waist ring 2 to share the pressure, the burden on the muscles, bones and joints of the injured arm can be reduced, and the comfort of the neck can be avoided from being affected by the binding strap hanging on the cervical vertebra. The arm on the supporting member 1 is bound and fixed through the binding strap 11 to reduce the self-movement of the affected limb. The mounting member 12 can adopt detachable connection methods such as snap buttons and magic tapes, but the mounting member 12 is not limited to snap buttons and magic tapes. Any mounting member 12 that can connect the movable end of the binding strap 11 to one end of the supporting member 1 and can adjust the binding range is acceptable. For example, Figure 1 As shown, when using a magic tape for connection, the overlapping area between the sub-magic tape and the mother magic tape can be adjusted according to the thickness of the affected limb. That is, the thinner the affected limb, the larger the overlapping area, and vice versa.

[0051] When the binding part binds the affected limb on the supporting part 1, the airbag 101 on the binding belt 11 and the pressure sensor 103 on the airbag 101 will contact the affected limb, and the pressure sensor 103 will detect the resistance between the binding belt and the affected limb. Since the binding belt 11 is connected to the supporting part 1, when the affected limb is swollen, the greater the resistance between the affected limb and the binding belt 11, the greater the pressure value detected by the pressure sensor 103. Anyway, when the affected limb gradually subsides, the resistance between the patient's limb and the binding belt 11 becomes smaller. At this time, in order to adjust the binding strength of the binding belt 11 according to the degree of swelling of the affected limb, the central control unit 4 will monitor the pressure value according to the pressure sensor 103. The measured pressure value is used to inflate and deflate the airbag 101. When the airbag 101 is in a larger state of inflation, the resistance force between the airbag and the affected limb is greater, and the binding force is also greater. For example, in the early stage of injury, the swelling of the arm gradually intensifies. At this time, the airbag 101 can be deflated to avoid the binding strap 11 being too tight and causing pressure on the swollen part, thereby reducing the patient's pain and discomfort; as the swelling gradually subsides, it can be appropriately inflated to maintain the effective fixation of the binding strap 11 on the arm. Through this dynamic adjustment capability, the arm can always be in a more comfortable fixed state, preventing the pressure of the binding strap 11 from failing to adjust in time when the arm is swollen. An overly tight binding strap 11 will hinder the blood circulation of the affected limb and affect wound healing.

[0052] like Figure 8 As shown, the two adjacent airbags 101 are connected through a branch air pipe 104, and the branch air pipe 104 is provided with an electric-controlled valve 105 electrically connected to the central control unit 4. The output end of the micro air pump 102 is provided with a main air pipe 106, and the main air pipe 106 is connected to multiple branch air pipes 104 respectively, for inflating and deflating a single airbag 101. Due to the different thicknesses or swelling degrees of the same arm, multiple airbags 101 can be provided, and the airbags 101 are inflated and deflated in a targeted manner at different positions. When the pressure sensor 103 detects that the pressure value of a certain part of the affected limb is large, the central control unit 4 can close the electric-controlled valves 105 in other areas, and open the electric-controlled valves 105 on the corresponding branch air pipes 104 on the airbags 101 that need to be inflated and deflated separately, and the micro air pump 102 is used to realize separate inflation and deflation of this airbag 101, so as to adapt to different swollen parts of the affected limb.

[0053] like Figures 1 to 5As shown, on both sides of the arc connecting portion 23, there are respectively connected a plug-in member 231 and a receiving member 232 that cooperates with the plug-in member 231. And on the plug-in member 231, there is a plug-in member 231 connected. A positioning button 233 is threadedly connected to the plug-in member 231. A positioning groove 234 corresponding to the positioning button 233 is provided on the receiving member 232. When the plug-in member 231 is inserted into the receiving member 232 on the adjacent arc connecting portion 23, the positioning button 233 is rotated and moves into the positioning groove 234, and two adjacent arc connecting portions 23 are connected;

[0054] On both side walls of the arc connecting portion 23, there are respectively connected a shaft pin 2302 through a mounting bracket 2301. The plug-in member 231 and the receiving member 232 are both movably connected to the arc connecting portion 23 through the shaft pin 2302;

[0055] When connecting or wearing the waist ring 2, first, the plug-in member 231 on one of the arc connecting portions 23 can be inserted into the receiving member 232 on the adjacent arc connecting member, so that the two arc connecting members are preliminarily fixed. Then, the positioning button 233 is rotated and moved towards the positioning groove 234, so that the positioning button 233 enters the positioning groove 234, thereby realizing the connection and fixation of two adjacent arc connecting portions 23 and preventing them from separating. When all the arc connecting portions 23 are connected, a closed waist ring 2 is formed. At this time, the moving member 22 also slides along the sliding track 21 on the outer side of the waist ring 2, so as to facilitate the swinging of the affected limb during support. And according to the waist size of the patient, the corresponding number of arc connecting portions 23 can be used for connection. At the same time, in order to facilitate the connection of multiple arc connecting portions 23 to form a closed state, when two adjacent arc connecting portions 23 are connected, a certain range of swinging is realized through the plug-in member 231 and the receiving member 232 under the action of the shaft pin 2302 to achieve the closing of the waist ring 2.

[0056] As Figure 6 and Figure 7 shown, the support member 3 includes a vertical rod 31 provided on the moving member 22, an adjusting rod 32 threadedly connected to the top end of the vertical rod 31, and a receiving rod 33 rotatably connected to the end of the adjusting rod 32 far from the vertical rod 31. By rotating the adjusting rod 32, the length of the support member 3 can be adjusted;

[0057] The connecting member includes a support platform 34 threadedly connected to the end of the receiving rod 33 far from the adjusting rod 32. The support platform 34 is slidably connected to the bottom of the supporting member 1 through a dovetail groove 35. Fasteners 36 are threadedly connected to both ends of the support platform 34. One end of the fastener 36 extends into the interior of the dovetail groove 35 to lock the supporting member 1 on the support platform 34.

[0058] After the waist ring 2 is worn on the patient's waist, the adjusting rod 32 is rotated according to the patient's arm length, so that the adjusting rod 32 drives the receiving rod 33 to move up or down, so as to adjust the supporting member 1 to the optimal height for supporting the affected arm. For example, when the patient needs to remove the waist ring 2 when lying down or in other states, at this time, the receiving rod 33 can be rotated to separate it from the support platform 34, and at this time, the affected limb is separately bound to the supporting member 1, and the flexibility of the affected limb is stronger, such as it can perform actions such as lifting upwards. And when it is necessary to move the supporting member 1 to the left or right to adapt to the use during the operation on the left arm or right arm, first, the supporting member 1 is moved to one side by the moving seat, and then the position of the supporting member 1 on the support platform 34 is slid, and the position of the supporting member 1 is fixed by rotating the fastening member 36 to tightly contact the two side walls of the supporting member 1. Usually, the support platform 34 is located below one end of the supporting member 1 rather than in the middle of the supporting member 1. That is, when the arm is placed on the supporting member 1, the elbow is roughly above the support platform 34. At this time, if the forearm needs to swing around the elbow during support, the supporting member 1 can be used to drive the receiving rod 33 to rotate on the adjusting rod 32.

[0059] As Figure 10 As shown, the central control unit 4 further includes a data processing module 41 and a first data storage module 42 that are electrically connected to the pressure sensor 103, which are used to receive the pressure data collected by the pressure sensor 103, and are used to record and store the pressure value detected by the pressure sensor 103 as a standard reference value when used for the first time, and set a pressure threshold range according to this standard reference value.

[0060] The central control unit 4 is electrically connected to a first warning module 43, and when the central control unit 4 receives that the pressure data monitored by the pressure sensor 103 is not within the set threshold stored in the first data storage module 42, it controls the first warning module 43 to issue a prompt.

[0061] When the patient uses it for the first time, after the binding member binds the affected limb to the appropriate tightness, the pressure sensor 103 collects the corresponding pressure data. At this time, the value recorded this time can be stored through an external confirmation button and used as the set threshold. When the subsequent swelling or other conditions of the affected limb cause the pressure value monitored by the pressure sensor 103 to be outside the initial recorded threshold range, a prompt can be issued by the first warning module 43. While prompting the patient or medical staff to perform corresponding operations, the adaptive unit will also make corresponding adjustments to adjust the binding strength to the optimal state.

[0062] As Figure 11As shown, a structural parameter detection unit 44 and a second data storage module 45 are provided on the waist ring 2. The structural parameter detection unit 44 includes a permanent magnet 441 provided on the side wall of the plug-in member 231 and a Hall element 442 provided on the inner wall of the receiving member 232. When two adjacent arc-shaped connecting portions 23 are connected, the change in magnetic field will cause the Hall element 442 to generate a voltage change, which is used to detect the number of arc-shaped connecting portions 23.

[0063] It further includes a data comparison and analysis module 46 and a second warning module 47. The data comparison and analysis module 46 is used to analyze the initial pressure data stored in the first data storage module 42 and the initial quantity data stored in the second data storage module 45. When it is determined that one of them is not within the initial data, the second warning module 47 issues a warning.

[0064] When the patient uses it for the first time, the number of arc-shaped connecting portions 23 is adjusted according to the different waist sizes of the patient. When the plug-in member 231 is inserted into the receiving member 232, the permanent magnet 441 approaches the Hall element 442, and the change in magnetic field will cause the Hall element 442 to generate a voltage change. At this time, it will be recorded that a set (two) of arc-shaped connecting portions 23 are connected, so as to judge the circumference of the entire waist ring 2. Similarly, the patient can store the circumference of the waist ring 2 at this time in the second data storage module 45 through an externally set confirmation button. When other patients use it, if only the circumference of the waist ring 2 is adjusted without adjusting the initial pressure value, the initial pressure at this time may not be completely suitable for this patient. Therefore, the second warning module 47 will issue a warning to remind the patient or medical staff to adjust in time, and the warning methods of the first warning module 43 and the second warning module 47 are different for easy distinction.

[0065] The working process of the technical solution provided by the present invention is as follows:

[0066] According to the waist size of the user, a waist ring 2 is formed by selecting an appropriate number of arc-shaped connecting portions 23 and worn on the patient's waist, and the height of the support member 3 is adjusted so that the supporting portion can effectively support the affected limb, and the gravity of the affected limb is transmitted to the waist. Then, after connecting the movable end of the binding belt 11 to one side of the supporting member 1 according to the binding strength that the patient can bear, the magnitude of the resistance force of the affected limb against the binding belt 11 detected by the pressure sensor 103 is recorded as the set pressure threshold, and as the swelling degree of the patient changes, the pressure data detected by the pressure sensor 103 changes, and the inflation and deflation of the airbag 101 are realized through the micro air pump 102 and the electric control valve 105, so as to realize the real-time adjustment of the binding pressure of the affected limb, and avoid discomfort caused by excessive binding strength and affecting the fixation effect due to too small binding pressure.

[0067] The present invention encompasses any alternatives, modifications, equivalent methods, and solutions that are within the spirit and scope of the present invention.
