Description

Technical Field

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

[0002] Orthopedic nursing auxiliary fixation refers to the use of various methods and instruments to fix the patient's fractured bones or injured joints during orthopedic nursing to promote fracture healing, relieve pain, prevent joint dislocation or deformity, etc. Common auxiliary fixation devices include splints, which are fixed to the injured limb through bandages or other fixation devices to limit the limb, and plaster bandages made of plaster of Paris powder and gauze. When the plaster bandage is soaked in water, the plaster of Paris will undergo a hydration reaction and gradually harden, so that it can be shaped according to the shape of the limb.

[0003] For patients with upper limb injuries, especially when the upper arm, such as the humerus, is fixed, in order to promote blood return to the heart from the arm, reduce swelling of the limb caused by fracture, and avoid fracture displacement caused by activity of the affected limb or muscle pulling, the affected limb is usually suspended by a bandage or a triangular bandage. Suspending the affected limb on the neck or shoulder can keep the patient's arm stable to a certain extent, and it is convenient for the patient to carry out other daily activities. However, suspending the upper limb on the neck with a bandage for a long time will change the center of gravity of the body. In order to balance the weight of the upper limb, the spine, especially the cervical and thoracic parts, will be forced to be in an unnatural posture, which may lead to changes in the physiological curvature of the spine, such as excessive cervical lordosis or increased thoracic kyphosis, thereby causing spinal muscle strain, which can cause spinal deformity in the long run, and long-term shoulder pain on one side. Bearing the weight of the upper limb, 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 shoulder muscle strength, with overdevelopment of the trapezius, deltoid and other muscles on one side and atrophy on the other side, which in turn causes shoulder pain, limited mobility and other problems. Fractures are often accompanied by damage to the surrounding soft tissues, including muscles, tendons, blood vessels and nerves. The inflammatory response of these soft tissues can cause local congestion and edema, or the local blood circulation may be affected, resulting in poor blood and lymph return, and then causing swelling. However, with the current splints or plasters, they are fixed on the limbs, and the swollen limbs will be compressed in the fixed splints, causing increased pain. If the splints are too tight, they will compress the limbs, resulting in obstructed blood circulation, which is not conducive to the recovery of the affected limb. Summary of the invention

[0004] In view of the problems in the prior art that long-term suspension of an affected limb affects the comfort of the cervical spine and swelling of the affected limb is not conducive to recovery, the purpose of the present invention is to provide an orthopedic nursing auxiliary fixation device.

[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, a plug-in connector and a socket connector matching the plug-in connector are respectively connected on both sides of the arc-shaped connecting portion, and a plug-in connector is connected to the 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 connector. When the plug-in connector is plugged into the socket connector on an adjacent arc-shaped connecting portion, the positioning knob is rotated to move into the positioning groove, and the two adjacent arc-shaped connecting portions are connected.

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

[0012] Optionally, the connecting member includes a support platform threadedly connected to one end of the receiving rod away from the adjusting rod, the support platform is slidably connected to the bottom of the receiving member via a dovetail groove, both ends of the support platform are threadedly connected with fasteners, one end of the fastener extends to the interior of the dovetail groove for locking the supporting member on the support platform.

[0013] Optionally, the two adjacent airbags are connected by a branch air pipe, and the branch air pipe is provided with an electrically controlled valve electrically connected to the central control unit. The output end of the micro air pump is provided with a main air pipe, and the main air pipe is connected to multiple branch air pipes respectively, for inflating and deflating a single airbag.

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

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

[0019] In the above scheme, the affected limb on the supporting member is supported by a waist ring and a supporting member worn on the waist, 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. The arm is supported by the waist ring and the sliding action of the moving member on the sliding track of the waist ring makes the arm relatively independent of the neck. The patient can adjust the body posture more naturally and can swing while the arm is supported, and the suspension strap will not cause discomfort to the neck during swinging.

[0020] By setting 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 strength 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 part, 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, and 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 appropriate binding force of the binding belt and the size of the waist ring for this patient can be recorded in a targeted manner. When other patients are replaced for use, 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, so that the user can adjust the pressure data of the binding belt and the size of the waist ring appropriately according to their own situation, so as to improve the use effect.

[0047] like Figures 1 to 11 As shown, an embodiment of the present invention provides an orthopedic nursing auxiliary fixation device, including a supporting member 1 for supporting an affected limb, wherein the supporting member 1 may be a structure with an arc-shaped cross-section, so that when the affected limb is placed in the supporting member 1, the affected limb is in a semi-wrapped state, and further includes a waist ring 2 worn on 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, and the upper end of the moving member 22 is connected to a supporting member 3, and 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, and the upper end of the supporting member 1.

[0048] A binding belt 11 is fixedly connected to one side of the upper end of the supporting member 1, and the movable end of the binding belt 11 is detachably connected to the side of the supporting member 1 away from the fixed end of the binding belt 11 through a mounting member 12. When the movable end of the binding belt 11 is connected to the supporting member 1, the patient located on the supporting member 1 can be bound. The binding belt 11 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 airbags 101 installed on the inner wall of the binding belt 11, a micro air pump 102 for inflating the airbags 101, a pressure sensor 103 arranged on the side of the airbag 101 away from the binding belt 11, and a central control unit 4 arranged on the movable member 22 and electrically connected to the pressure sensor 103, and the central control unit 4 is used to control the filling degree of the airbag 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 each other, so as 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 patients, an appropriate number of arc-shaped connecting parts 23 are selected to form a waist ring 2 of appropriate size. The size of the waist ring 2 is optimal when it can be stuck at the waist and will not fall down. Then the affected arm of the upper limb is placed on the support member 1, and the waist ring 2 and the support member 3 are used to support the affected limb on the support member 1. The human waist is relatively stronger than the human body to bear the additional load. When the arm is injured, it is difficult for the body to bear its weight. With the help of 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 caused by the strap hanging at the cervical vertebra can be avoided. The arm on the support member 1 is bound and fixed by the binding belt 11 to reduce the movement of the affected limb itself. The mounting member 12 can adopt a detachable connection method such as a snap button and Velcro, but the mounting member 12 is not limited to snap buttons and Velcro. The mounting member 12 can connect the movable end of the binding belt 11 to one end of the support member 1 and can adjust the binding range, such as Figure 1 As shown, when Velcro is used for connection, the size of the overlapping area between the sub-Velcro and the main Velcro 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 member binds the affected limb on the supporting member 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 member 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 sensor 103 according to the resistance between the affected limb and the binding belt 11. The measured pressure value is used to inflate and deflate the airbag 101. When the airbag 101 is in a larger state of filling, the greater the resistance between the airbag and the affected limb, the greater the binding force. For example, in the early stage of injury, the swelling of the arm gradually increases. At this time, the air can be deflated to avoid the binding belt 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 arm by the binding belt 11. Through this dynamic adjustment capability, the arm can always be in a more comfortable fixed state, preventing the pressure of the binding belt 11 from failing to adjust in time when the arm is swollen. An overly tight binding belt 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 via a branch air pipe 104, and the branch air pipe 104 is provided with an electrically 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 respectively connected to multiple branch air pipes 104, and is used to inflate and deflate 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 specifically inflated and deflated 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 electrically controlled valves 105 in other areas, and open the electrically 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 the separate inflation and deflation of this airbag 101, so as to adapt to the different swelling parts of the affected limb.

[0053] like Figures 1 to 5As shown, the two sides of the arc-shaped connecting portion 23 are respectively connected with a plug-in connector 231 and a receiving member 232 matched with the plug-in connector 231, and the plug-in connector 231 is connected with a plug-in connector 231, and a positioning button 233 is threadedly connected to the plug-in connector 231, and a positioning groove 234 corresponding to the positioning button 233 is opened on the receiving member 232. When the plug-in connector 231 is plugged into the receiving member 232 on the adjacent arc-shaped connecting portion 23, the positioning button 233 is rotated to move into the positioning groove 234, and the two adjacent arc-shaped connecting portions 23 are connected;

[0054] The side walls of the arc-shaped connecting part 23 are connected with shaft pins 2302 through the mounting frame 2301, and the plug-in component 231 and the receiving component 232 are movably connected with the arc-shaped connecting part 23 through the shaft pins 2302;

[0055] When the waist ring 2 is connected or worn, the connector 231 on one of the arc-shaped connecting parts 23 can be first inserted into the receiving part 232 on the adjacent arc-shaped connecting part to preliminarily fix the two arc-shaped connecting parts, and then the positioning button 233 is rotated to move in the direction of the positioning groove 234 so that the positioning button 233 enters the positioning groove 234, thereby connecting and fixing the two adjacent arc-shaped connecting parts 23 so that they will not disengage. When multiple arc-shaped connecting parts 23 are connected, a closed waist ring 2 is formed. At this time, the moving part 22 also slides along the sliding track 21 outside the waist ring 2 to facilitate the swing of the affected limb during support, and the corresponding number of arc-shaped connecting parts 23 can be used for connection according to the waist size of the patient. At the same time, in order to facilitate the connection between multiple arc-shaped connecting parts 23 to form a closed state, when two adjacent arc-shaped connecting parts 23 are connected, the connector 231 and the receiving part 232 can swing within a certain range under the action of the shaft pin 2302 to realize the closure of the waist ring 2.

[0056] like Figure 6 and Figure 7 As shown, the support member 3 includes a vertical rod 31 disposed on the moving member 22, an adjusting rod 32 threadedly connected to the top of the vertical rod 31, and a receiving rod 33 rotatably connected to an end of the adjusting rod 32 away from the vertical rod 31, and the length of the support member 3 is adjusted by rotating the adjusting rod 32;

[0057] The connecting member includes a support platform 34 threadedly connected to one end of the receiving rod 33 away from the adjusting rod 32, and the support platform 34 is slidably connected to the bottom of the receiving member 232 via a dovetail groove 35. Both ends of the support platform 34 are threadedly connected with fasteners 36, and one end of the fastener 36 extends to the inside of the dovetail groove 35 for locking 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 upward or downward, so as to adjust the supporting member 1 to the optimal height for supporting the affected arm. For example, when the patient needs to take off the waist ring 2 in a lying state, the receiving rod 33 can be rotated to separate from the support platform 34, and the affected limb is now separately bound to the supporting member 1, and the affected limb is more flexible, such as being able to lift up, and when the supporting member 1 needs to be moved to the left or right side to adapt to the use during surgery on the left or right arm First, the supporting member 1 is driven to move to one side by the moving seat, and then the position of the supporting member 1 is fixed by sliding the supporting member 1 on the supporting platform 34 and rotating the fastener 36 to tightly contact the side walls of the two ends of the supporting member 1. Normally, the supporting 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 located above the supporting platform 34. At this time, if the forearm needs to swing with the elbow as the center, the supporting member 1 can drive the receiving rod 33 to rotate on the adjusting rod 32.

[0059] like Fig.10 As shown, the central control unit 4 also includes a data processing module 41 and a first data storage module 42 electrically connected to the pressure sensor 103, which are used to receive pressure data collected by the pressure sensor 103, and 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 the pressure threshold range according to the standard reference value.

[0060] The central control unit 4 is electrically connected to a first warning module 43 . When the central control unit 4 receives information indicating that the pressure data monitored by the pressure sensor 103 is not within a 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 device binds the affected limb to a suitable tightness, the pressure sensor 103 collects the corresponding pressure data. At this time, the recorded value can be stored through an external confirmation button and used as a set threshold. When the affected limb subsequently swells, etc., causing the pressure value monitored by the pressure sensor 103 to be out of the initial recorded threshold range, a prompt can be issued together with the first warning module 43 to prompt the patient or medical staff to perform corresponding operations. At the same time, the adaptive unit will also make corresponding adjustments to adjust the binding force to the optimal state.

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

[0063] It also 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 of the second data storage module 45. When it is determined that one of the two is not in 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 parts 23 is adjusted according to the different waist sizes of the patients. When the connector 231 is inserted into the receiving part 232, the permanent magnet 441 is close to the Hall element 442. The change in magnetic field will cause the Hall element 442 to produce a voltage change. At this time, it will be recorded that a group (two) of arc-shaped connecting parts 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 the external confirmation button. When other patients are replaced, 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 make adjustments 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 workflow of the technical solution provided by the present invention is as follows:

[0066] According to the waist size of the user, a suitable number of arc-shaped connecting parts 23 are selected to form a waist ring 2 worn on the patient's waist, and the height of the support part 3 is adjusted so that the supporting part can effectively support the affected limb to transfer the gravity of the affected limb to the waist. Then, according to the binding force that the patient can withstand, the movable end of the binding belt 11 is connected to one side of the supporting part 1, and the resistance force of the affected limb on the binding belt 11 detected by the pressure sensor 103 is recorded as the set pressure threshold. As the degree of swelling of the patient changes, the pressure data detected by the pressure sensor 103 changes, and the micro air pump 102 and the electric control valve 105 are used to inflate and deflate the airbag 101, so as to realize real-time adjustment of the binding pressure of the affected limb, so as to avoid excessive binding force causing discomfort to the patient and too little binding pressure affecting the fixation effect.

[0067] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0068] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
