Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of medical care equipment, and particularly relates to an emergency care bandaging support device for limb isolation, elevation and fixation, which is suitable for scenarios such as upper limb fracture, postoperative rehabilitation, shoulder injury and the like that need to avoid limb load. BACKGROUND

[0002] In emergency clinical and postoperative care, the upper limb needs to be kept in a specific position (such as elevation and fixation) for a long time due to reasons such as fracture, dislocation and surgery, so as to promote venous return, reduce swelling and reduce the risk of secondary injury. The current mainstream clinical method is to use a sling support device, which suspends the upper limb from the patient's shoulder by a cloth or fabric sling to achieve support, but this technology has the following defects that cannot be ignored: 1. Pressure injury risk is prominent: the support force of the sling completely depends on the neck and shoulder, and long-term wearing can easily cause local soft tissue compression, causing neck muscle strain, shoulder pain, and even compression of the cervical spine nerve, inducing nerve lesions; 2. The applicable scene is limited: if the patient's shoulder is also injured (such as rotator cuff injury or clavicle fracture) or is in the postoperative recovery period, the sling cannot provide effective support and will instead aggravate the shoulder injury, forming a "nursing contradiction"; in addition, for patients with shoulder injury, the shoulder also needs to be kept in a certain posture for support to promote healing during healing; 3. Insufficient support stability: cloth materials are prone to sliding and deformation, and cannot accurately control the elevation angle and horizontal distance of the limb, making it difficult to meet individual needs.

[0003] In view of the above technical problems, the present application aims to provide a support device that does not require a sling and integrates multi-dimensional adjustment and multifunctional assistance to solve the defects of the prior art from the structural design. SUMMARY

DETAILED DESCRIPTION

[0038] The application will be further described in detail in combination with the drawings. The drawings are simplified schematic diagrams, and only schematically illustrate the basic structure of the application, and thus only show the components related to the application.

[0039] In the prior art, the medical care field often uses a sling support device to fix the upper limbs of patients with fractures or postoperative patients. Such a device suspends the limbs from the neck or shoulder through a cloth sling, which can easily cause local pressure injury and cause cervical spine strain or nerve compression after long-term use. For patients with shoulder injuries, the sling cannot provide effective support, but instead aggravates the condition, especially for patients who need important and long-term fixation, the problem of pressure injury is more prominent; in addition, for patients with shoulder injuries, the shoulder also needs to be supported during healing; the traditional device has the problems of unadjustable support angle, poor stability and single function, and cannot meet the needs of lower limb bandaging.

[0040] As shown in Figure 1 、 Figure 2 、 Figure 14 The present application provides a bandaging and supporting device for emergency care, which comprises a first fixing member 1 fixed to the proximal end of the limb and a second fixing member 2 fixed to the distal end of the limb. The first fixing member 1 and the second fixing member 2 are connected by an adjustable suspension assembly 3. The suspension assembly 3 includes a suspension rod 301 with a first adjusting slide 302 and a slidingly connected pull rod 303. The pull rod 303 is provided with a second adjusting slide 304. The support pad assembly 4 includes a positioning pad 401, a placement pad 402 and an adjusting mechanism. The positioning pad 401 is detachably connected to the first fixing member 1, and the placement pad 402 is detachably connected to the second fixing member 2. The suspension rod 301 and the pull rod 303 form a cantilever support structure. A tension belt 7 is fixed to the second fixing member 2 and generates an inward tension. A fixing belt 8 is connected to the positioning pad 401 and fixed to the waist.

[0041] The suspension rod 301 is a rigid rod member extending outwardly from the first fixing member 1, which can be made of aluminum alloy. The first adjusting slide 302 provided on the surface of the suspension rod 301 can be an arc-shaped groove structure. The pull rod 303 is a support component that is connected to the suspension rod 301 by sliding connection. The adjustable suspension assembly 3 is a mechanism that achieves position locking through a slide and a screw assembly. The adjusting mechanism in the support pad assembly 4 is a device that can change the relative position of the positioning pad 401 and the placement pad 402, such as a crank slider mechanism composed of a connecting rod and a slider 16 to achieve angle adjustment.

[0042] Specifically, the proximal end of the limb is fixed to the starting end of the suspension rod 301 by the first fixing member 1, and the distal end is fixed to the end of the pull rod 303 by the second fixing member 2. The sliding connection of the suspension rod 301 and the pull rod 303 allows horizontal length adjustment, and the second adjustment slide 304 realizes vertical height adjustment. The positioning pad 401 of the support pad assembly 4 is fixed to the waist of the patient, and the shoulder abduction distance and angle of the patient are adjusted; the placement pad 402 supports the elbow, and the distance between the two is changed by the adjusting mechanism. The cantilever support structure forms a rigid force transmission path, and the inward lateral tension applied by the tension belt 7 balances the weight of the limb, and the fixing belt 8 disperses the support force to the waist. When the position of the adjusting slide is locked, the device forms a stable triangular support system, avoiding the compression of the traditional sling on the shoulder and neck.

[0043] Compared with the prior art, the application avoids the risk of pressure injury of the neck and shoulder, and is suitable for the rehabilitation care of patients with shoulder injury. The cantilever support structure provides stable mechanical support to prevent secondary injury caused by limb displacement. The adjustable slide and pad distance design adapts to patients of different body types and different support needs, improving the universality of the device. The combination of rigid support and elastic tension belt 7 maintains a moderate activity space while fixing the limb, promoting blood circulation.

[0044] As shown in Figure 14 , Figure 15 , Figure 16 The first screw assembly 5 and the second screw assembly 6 are further provided in the application, and the structures of the first screw assembly 5 and the second screw assembly 6 are the same, both including a limiting washer 9 provided on the outer side of the pull rod 303 and having a positioning protruding column 10; the suspension rod 301 is provided with a plurality of first positioning holes 11 along the first adjusting slide 302, and the pull rod 303 is provided with a plurality of second positioning holes 12 along the second adjusting slide 304, and the positioning protruding column 10 cooperates with the first positioning hole 11 or the second positioning hole 12 to realize position locking. The limiting washer 9 refers to a rigid component installed on the outer side of the pull rod 303, which can be made of metal or high-strength plastic, and the positioning protruding column 10 provided on the surface thereof can be inserted into the positioning hole on the adjusting slide, which is used to limit the relative displacement between the pull rod 303 and the suspension rod 301. The first positioning hole 11 and the second positioning hole 12 refer to circular through holes 30 distributed at intervals along the adjusting slide, which can be arranged at equal intervals, for example, with a hole spacing of 5-10 mm, and multi-stage position adjustment is realized by cooperation of the positioning protruding column 10 with different hole positions. Specifically, when the horizontal or vertical position of the suspension rod 301 and the pull rod 303 needs to be adjusted, the operator loosens the screw assembly and moves the pull rod 303 or the second fixing member 2 along the slide, and then inserts the positioning protruding column 10 into the corresponding positioning hole when reaching the target position, and then completes the locking by tightening the screw.

[0045] By the technical scheme, the standardized screw assembly is matched with the positioning hole to ensure accurate locking of the limb support angle and height, reduce operation complexity, and be suitable for individual adjustment needs of patients with different body types.

[0046] As shown in Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 The adjustment mechanism further includes the first connecting plate 13 fixed with the positioning pad 401, the second connecting plate 14 fixed with the placement pad 402, and two symmetrically arranged adjustment assemblies, each of which includes the first connecting rod 15 hingedly connected to one end of the first connecting plate 13, and the adjustable locking slider 16 hingedly connected to the other end of the first connecting rod 15 and horizontally slidably connected to the second connecting plate 14. The first connecting plate 13 is a plate-shaped structure rigidly connected to the positioning pad 401, which can be made of metal or high-strength plastic material, and is used to transmit the support force of the positioning pad 401 to the adjustment mechanism. The second connecting plate 14 is a plate-shaped structure rigidly connected to the placement pad 402, which can be made of the same material as the first connecting plate 13, and is used to bear the support force of the placement pad 402 and realize linkage with the adjustment assembly. The adjustment assembly is a mechanical structure symmetrically distributed between the first connecting plate 13 and the second connecting plate 14, which can be realized by a combination of connecting rods and sliders 16, and is used to adjust the relative position between the two connecting plates by changing the geometric relationship. The first connecting rod 15 is a rigid rod hingedly connected to the first connecting plate 13 and the slider 16 at both ends, which is used to change the angle between the first connecting plate 13 and the second connecting plate 14 when the slider 16 moves. The adjustable locking slider 16 is a movable part that slides horizontally along the second connecting plate 14, which can be realized by a metal block with a locking bolt, and is used to fix the distance between the two connecting plates after sliding to the target position. Specifically, the positioning pad 401 and the placement pad 402 are rigidly connected through the first connecting plate 13 and the second connecting plate 14 respectively, and the two symmetric adjustment assemblies are located on both sides of the connecting plates. When the slider 16 slides horizontally along the second connecting plate 14, the hinge point of the first connecting rod 15 moves, driving the distance and included angle between the first connecting plate 13 and the second connecting plate 14 to change synchronously. By adjusting the sliding distance of the sliders 16 on both sides, the parallel movement or the change of the inclination angle of the two connecting plates in the horizontal direction can be controlled, thereby realizing the position adjustment between the positioning pad 401 and the placement pad 402. After the slider 16 is locked, the hinge point of the first connecting rod 15 and the slider 16 forms a stable support, preventing the adjusted position from being deviated by external force. By the technical solution, the spatial position and contact angle of the support pad can be flexibly adjusted according to the shoulder shape of the patient and the rehabilitation stage requirement, for example, a larger interval is adopted in the early postoperative stage to avoid pressing the wound, and the interval is reduced in the later rehabilitation stage to enhance the stability. The symmetrical adjusting assembly can balance the support force distribution on both sides, prevent the skin from being damaged due to excessive unilateral pressure, and adapt to the physiological characteristics of the asymmetric left and right shoulders.

[0047] Locking mode of the adjusting mechanism: Mode one (screw adjusting): the middle part of the second connecting plate 14 is rotationally connected with the adjusting screw 17 (threadedly matched with the sliding block 16), and the operation handle 18 is arranged at the end of the screw; the sliding block 16 is driven to horizontally slide by rotating the handle, the first connecting rod 15 is rotated, the interval and angle of the positioning pad and the placement pad are adjusted, and the position is locked by the screw self-locking feature.

[0048] Mode two (mechanical limiting): as shown in Figure 7 , the end part of the first connecting rod 15 is rotationally connected with the limiting rod 20, the two limiting blocks 21 are symmetrically arranged on the second connecting plate 14, a plurality of limiting grooves 22 distributed along the moving direction of the limiting rod 20 are arranged in each limiting block 21, and the tension spring 23 is connected between the limiting rod 20 and the second connecting plate 14. The limiting rod 20 is a rigid rod member rotationally connected with the end part of the first connecting rod 15, which can be realized by a metal rod or a high-strength plastic rod, and the function is to change the matching position of the limiting rod 20 and the limiting groove 22 by rotation, so as to control the locking state of the sliding block 16. The limiting block 21 is a positioning component fixed on the two sides of the second connecting plate 14, which can be realized by a metal block with a groove or an injection molded part, and the function is to provide a plurality of fixed clamping positions for the limiting rod 20 by arranging a plurality of equidistantly distributed limiting grooves 22, so as to realize the position locking of the sliding block 16. The limiting groove 22 is a groove structure arranged on the limiting block 21, which can be realized by a rectangular groove or a semicircular groove, and the function is to realize the horizontal displacement locking of the sliding block 16 by embedding the limiting rod 20 in different positions of the limiting groove 22. The tension spring 23 is an elastic element connected between the limiting rod 20 and the second connecting plate 14, or connected between the two limiting rods 20, which can be realized by a spiral spring, and the function is to make the limiting rod 20 always have a tendency to move to the limiting groove 22 by the elastic tension, so as to maintain the stability of the locking state. Specifically, when the distance between the positioning pad 401 and the placement pad 402 needs to be adjusted, the operator pulls the limiting rod 20 outward to make it disengage from the current limiting slot 22, at this time the tension spring 23 is stretched to generate a restoring force. In the state of keeping the limiting rod 20 disengaged from the limiting slot 22, the horizontal moving slider 16 is moved to the target position and then the limiting rod 20 is released, the elastic restoring force of the tension spring 23 drives the limiting rod 20 to be embedded in the limiting slot 22 of the corresponding position, and the position locking is completed. The two symmetrically arranged limiting blocks 21 form double locking through the front and rear distributed limiting slots 22, avoiding the offset of the slider 16 caused by unilateral force. Through the above technical scheme, the shoulder support pad distance can be quickly adjusted and reliably locked, the support angle can be quickly adjusted according to the patient's body size difference in the emergency nursing scene, and the accidental loosening caused by vibration of the traditional threaded locking mechanism is avoided, and the stability and operation convenience of the shoulder support are significantly improved.

[0049] As shown in Figure 3 , Figure 7 , the application further proposes that the annular elastic belt 24 is fixedly connected between the first connecting plate 13 and the second connecting plate 14 in order to cover the space between the first connecting plate 13 and the second connecting plate 14 and can deform with it. Among them, the annular elastic belt 24 refers to a belt structure with elastic deformation ability, which can be made of silica gel, rubber material or fabric, and can wrap the gap between the connecting plates through the annular form. The elastic belt can deform synchronously when the adjusting mechanism changes the distance or angle, maintaining the integrity of the covered area. Specifically, when the adjusting mechanism drives the first connecting plate 13 and the second connecting plate 14 to produce relative displacement or angle change, the annular elastic belt 24 is stretched or compressed with the movement of the connecting plate, always covering the space between the two. For example, during the shoulder support process, if the adjusting mechanism moves the placement pad 402 outward, the elastic belt fills the gap between the connecting plates through deformation, preventing external foreign matter from entering the inside of the support structure. At the same time, the annular fixing mode of the elastic belt ensures the stability of the connection with the connecting plate, preventing it from falling off due to repeated adjustment.

[0050] Through the above technical scheme, the application effectively prevents external foreign matter from invading the internal structure of the support device, avoiding the jamming or wear of mechanical parts caused by pollution. At the same time, the flexible deformation characteristics of the elastic belt ensure the integrity of the overall structure of the support device during the adjustment process, improving the comfort and safety of the patient during use.

[0051] As shown in Figure 13 , the application further proposes that the front and rear directions of the positioning pad 401 are provided with a through concave arc-shaped structure 4011, and the left and right sides of the positioning pad 401 are provided with support grooves 4012, and the cross section of the support grooves 4012 is an isosceles trapezoid with wide top and narrow bottom. The lower concave arc structure 4011 refers to a concave arc profile formed along the width direction of the positioning pad 401, which facilitates the support and placement of the lower limbs. The support groove 4012 refers to a trapezoidal groove located on the side of the positioning pad 401. Specifically, it can be realized by opening a groove structure with an isosceles trapezoidal cross-section on the surface of the silica gel material. The design of the trapezoidal cross-section with the upper wide and lower narrow can adapt to different thicknesses of the upper limbs. Specifically, when the lower limbs need to be bandaged, the operator can place the patient's lower limbs in the lower concave arc structure 4011 of the positioning pad 401. The arc-shaped recess can effectively wrap the lower limbs and distribute the contact pressure. When supporting the upper limbs, the patient's upper limbs can be embedded in the support groove 4012 on the side of the positioning pad 401. The upper wide part of the trapezoidal cross-section can accommodate the elbow joint, and the lower narrow part can form stable contact with the distal end of the arm. The isosceles trapezoidal cross-section design of the support groove 4012 allows the upper limbs to be self-centered when placed, avoiding lateral movement of the limbs in the groove. Through the above technical solutions, the application realizes adaptive support for different limb parts. When the lower limbs are bandaged, it can prevent lateral sliding of the limbs. When the upper limbs are supported, it can avoid pressure on the joint parts. The isosceles trapezoidal support groove 4012 structure ensures the stability of the upper limbs while reducing the problem of local pressure concentration caused by size differences of the limbs.

[0052] As shown in Figure 14 The first fixing member 1 and the second fixing member 2 are further modularly designed, including a basic fixing ring 24 provided with an elastic connecting belt 25, and a replaceable limb fitting sleeve 26. The fitting sleeve 26 is divided into multiple specifications according to different limb diameters, and the inner wall of the fitting sleeve 26 is provided with an anti-slip silica gel strip. The basic fixing ring 24 refers to a basic support structure around the proximal or distal end of the limb, which can be realized by a ring-shaped frame structure with an opening. The opening is adjusted to form a closed structure by the elastic connecting belt 25 to adapt to the fixing needs of different limb circumferences. The elastic connecting belt 25 is an elastic component connecting the two ends of the opening of the basic fixing ring 24, which can be realized by an elastic cloth belt, silica gel or rubber material belt structure, providing flexible fixing force through elastic deformation. The replaceable limb fitting sleeve 26 is a contact component that is sleeved on the inner side of the basic fixing ring 24, which can be realized by a flexible sleeve structure with a split design. The inner diameter specifications can be set to multiple gradient sizes according to the diameter difference of the patient's limbs. The anti-slip silica gel strip is a protruding structure extending longitudinally along the inner wall of the fitting sleeve 26, which can be realized by a molding process to form continuous or intermittent strip patterns on the inner surface of the silica gel sleeve. It prevents the device from shifting by increasing the friction force of the contact surface. Specifically, the base fixing ring forms an adjustable circumference annular support frame through the elastic connecting belt 25, and when it is necessary to adapt to different limb sizes, an adaptive sleeve 26 corresponding to the inner diameter specification can be selected and embedded in the inner side of the base fixing ring. During operation, the elastic connecting belt 25 allows the base fixing ring to adapt to slight changes in the circumference of the limb while maintaining structural rigidity, and the modular design of the adaptive sleeve 26 allows medical personnel to quickly replace the matching size sleeve according to the actual limb diameter of the patient. The anti-slip silicone strip forms a directional frictional resistance on the contact surface between the adaptive sleeve 26 and the limb, and when the limb moves slightly, the shear resistance generated by the strip-shaped convex stripes can effectively inhibit the sliding of the device. Through the above technical solutions, the present application realizes precise adaptation to patients with different limb sizes, the anti-slip structure effectively improves the stability of the device in dynamic use, the modular design significantly reduces the equipment procurement and management costs of medical institutions, and at the same time reduces the repeated adjustment operation time caused by size mismatch.

[0053] As shown in Figure 6 , Figure 8 , the present application further proposes that in order to facilitate dehumidification and heat dissipation, the inside of the first connecting plate 13 is provided with a heat dissipation structure, the inside of the first connecting plate 13 is provided with a heat dissipation structure, a plurality of parallel micro fans 28 are embedded in the side wall of the placement pad 402, a plug 29 is integrated on the outer side wall of the first connecting plate 13, a honeycomb-shaped vent hole array 27 penetrates the thickness direction of the placement pad 402, a plurality of through holes 30 penetrate the thickness direction of the second connecting plate 14, and the lower end of the micro fan 28 is provided with a heating / cooling circulation line. Among them, the micro fan 28 refers to a plurality of parallel heat dissipation devices embedded between the first connecting plate 13 and the second connecting plate 14, which can be realized by using a brushless motor driven axial flow fan, and the embedded position can form a directional air flow channel. The honeycomb-shaped vent hole array 27 refers to a group of heat dissipation holes with circular or hexagonal hole structures, which can increase the heat exchange efficiency by increasing the surface area. The through hole 30 refers to a circular or square hole or any other hole that penetrates the plate, which is used to establish an air convection path. The plug 29 refers to a power input interface, which can be integrated on the outer side of the device in the form of a USB-C interface, which is convenient for connecting a mobile power supply. The forced air flow promotes the air flow in the contact area between the placement pad 402 and the limb. The heating or cooling circulation line refers to a temperature regulation module integrated below the micro fan 28, which can be realized by using a semiconductor refrigeration sheet combined with a heat-conducting copper pipe circuit, which can control the cooling or heating mode by switching the current direction, thereby actively adjusting the surface temperature of the placement pad 402.

[0054] Specifically, the micro fan 28 introduces external air into the placement pad 402 through the honeycomb vent array 27 to accelerate the evaporation of moisture for dehumidification and heat dissipation. The heating or refrigeration circulation line is stacked with the micro fan 28 in an up-down structure. When heating is needed, the heating mode is started, and heat is transferred to the surface of the placement pad 402 through the heat-conducting copper pipe; when cold compress is needed, the refrigeration mode is switched, and cold is conducted through the same path. During operation, the plug 29 can power the micro fan 28 and the circulation line, and the through hole 30 cooperates with the honeycomb vent to maintain air circulation. Thus, the temperature of the supported part can be dynamically adjusted according to the nursing needs. Compared with the prior art, the conventional support device only relies on passive heat dissipation materials or external ice packs for temperature control, and cannot simultaneously realize the functions of heat preservation and cold compress in a single body position, and the temperature adjustment needs to interrupt the nursing operation. The scheme can switch the temperature mode in real time during continuous support by integrating an active temperature control module, thereby avoiding the risk of limb displacement caused by frequent replacement of cold and hot compresses. Through the above technical solutions, the application can effectively reduce swelling through the cold compress mode in the acute stage of fracture and promote blood circulation through the heat preservation mode in the rehabilitation stage, while maintaining the stability of the support structure. The temperature adjustment process does not need to disassemble the device or adjust the limb position, reduces the possibility of secondary injury caused by operation, and improves the comfort of patients in different treatment stages.

Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
