Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical appliances, and particularly to a rapid dressing device for trauma orthopedics. Background Art
[0002] In the clinical practice of trauma orthopedics, forearm fractures (such as ulna and radius fractures) are common acute injuries, accounting for about 10%-15% of all body fractures. The traditional emergency fixation methods mainly use wooden or plastic splints combined with elastic bandages for dressing and fixation. Although this method has been used for many years, it has exposed many technical defects and clinical pain points in practical applications: High professional dependence The existing splint fixation technology has high requirements for the professional skills of operators. According to the clinical research statistics of the Journal of Emergency Medicine in 2022, about 43% of non-professional first-aid personnel will have the situation of over-tight fixation (resulting in limb ischemia) or over-loose fixation (fixation failure) when trying to use traditional splints. The tightness of the bandage winding needs to be dynamically adjusted according to the swelling degree of the injured limb, and this process often requires relying on the palpation experience and manual training of medical staff.
[0003] Poor anatomical adaptability Standard splints are mostly straight plate designs and are difficult to fit the unique spiral anatomical structure of the forearm. Clinical observations show that 28% of patients using traditional splints will have the phenomenon of the splint edge compressing the ulnar nerve or the radial nerve (data source: the 4th issue of Orthopedic Nursing in 2023). In addition, the existing products lack a length adjustment mechanism and have poor adaptability for special groups such as children and obese patients.
[0004] Lack of dynamic fixation During the patient transfer process (especially in the pre-hospital emergency scenario), the traditional fixation device cannot adapt to the body position change. When the patient changes from the standing position to the supine position, the fixed limb often forms an abnormal angle with the trunk due to the gravity effect, which not only aggravates the pain but also may cause secondary displacement of the fracture end. The statistics of the trauma department of a certain tertiary hospital show that about 19% of the transferred patients have complications due to the inability of the fixation device to adjust with the body position.
[0005] Low operation efficiency The existing technology requires two-handed coordinated operation: one hand fixes the position of the splint, and the other hand winds the bandage. In special scenarios such as disaster medicine or battlefield first aid, this operation mode seriously delays the treatment time. Experimental data shows that it takes an average of 4.5 minutes for skilled medical staff to complete traditional fixation, while it takes more than 8 minutes for novices.
[0006] Comfort defect Traditional materials have poor air permeability, and long-term fixation can easily lead to skin maceration. Especially for plaster splints, their surface temperature can be 2-3°C higher than the ambient temperature (research in the Journal of Biomedical Engineering in 2021), significantly increasing the discomfort of patients. In addition, rigid fixation will limit the micro-movement of the wrist joint, affect lymphatic return, and exacerbate limb swelling.
[0007] In response to the above problems, some improved technologies have emerged in recent years, such as inflatable splints, memory polymer splints, etc. However, these solutions still have new defects such as high costs, requiring power support (intelligent adjustable splints), or being non-reusable. Therefore, there is an urgent need in clinical practice for a new type of fixation device that combines rapid operation, dynamic adaptation, and controllable costs. Summary of the Invention

[0029] In this embodiment, the clamping unit 1 further includes a traction belt 11 and a fastening assembly; there are two configured traction belts 11, symmetrically arranged on both sides of the clamping unit 1; both ends of the traction belt 11 are respectively fixed to the sides of the two clamping plates 6; the length of the traction belt 11 is greater than the diameter of the clamping unit 1; when the two clamping plates 6 are in the open state, the patient's arm first contacts the traction belt 11, and when the traction belt 11 is pressed down, it pulls the two clamping plates 6 at both ends thereof to close inward, causing the two clamping plates 6 to snap together, facilitating the single-handed operation of closing and locking the clamping plates 6; the fastening assembly includes a lifting module provided on the slider 5 and a pressing module provided on the clamping plate 6; The lifting module includes a lifting seat 14 and a lifting plate 13; the lifting seat 14 is fixed on the slider 5, and the lifting plate 13 is hinged to the lifting seat 14; the axis of the hinge joint between the lifting plate 13 and the lifting seat 14 is perpendicular to the axis of the guide rod 18 in space, enabling the lifting plate 13 to deflect within a certain range, so that the lifting plate 13 can lift the patient's arm at an angle that fits the patient's arm. The pressing module includes a lower pressing plate 10, a vertical adjuster 9, and a horizontal adjuster 12; the lower pressing plate 10 is spaced inside the clamping plate 6; the vertical adjuster 9 is placed above the lower pressing plate 10, and the horizontal adjuster 12 is placed on one side of the lower pressing plate 10; when the two clamping plates 6 are snapped and fixed, the lower pressing plate 10 presses on the upper side of the patient's arm; the vertical adjuster 9 is used to adjust the pressing force of the lower pressing plate 10; The vertical adjuster 9 includes a first guide sleeve 37, a first screw 19, a first nut 25, a sliding ring 24, a support rod 20, and a first joint bearing 23; the first guide sleeve 37 is fixed to the clamping plate 6; the first screw 19 is slidably arranged in the first guide sleeve 37, and the lower end is hinged to the sliding ring 24; the first nut 25 is sleeved on the first screw 19, and the upper end surface abuts against the inner side surface of the clamping plate 6; the first joint bearing 23 is installed on the outer side surface of the lower pressing plate 10; the support rod 20 is slidably arranged in the sliding ring 24, one end is hinged to the clamping plate 6, and the other end is installed in the first joint bearing 23; by rotating the first nut 25, the length of the first screw 19 extending below the first guide sleeve 37 is adjusted, and the sliding ring 24 slides on the support rod 20 to adjust the inclination angle of the support rod 20, so that the vertical position of the lower pressing plate 10 is adjustable in the vertical plane; the first joint bearing 23 enables the lower pressing plate 10 to tilt at a certain angle to better fit the contour curve of the patient's arm; The horizontal adjuster 12 includes a second guide sleeve, a second screw rod 22, a second nut 21 and a second spherical plain bearing 36; the second guide sleeve is hinged to the clamping plate 6; the second spherical plain bearing 36 is installed on the outer side surface of the lower pressing plate 10; the second screw rod 22 is slidably arranged in the second guide sleeve, and one end is installed in the second spherical plain bearing 36; the second nut 21 is sleeved on the second screw rod 22, and the outer side surface is in abutting contact with the inner side surface of the clamping plate 6. Rotating the second nut 21 adjusts the length of the second screw rod 22 extending out of the second guide sleeve, so that the lower pressing plate 10 approaches the patient's arm in the horizontal direction; the second guide sleeve can be linked with the vertical adjuster 9 to prevent the vertical adjuster 9 from being stuck.
[0030] In this embodiment, the lifting plate 13 and the lower pressing plate 10 are hollow arc-shaped plates to reduce the overall weight of the device, and the inner side surfaces are both configured with curved surfaces that fit the contour of the arm; a plurality of ventilation through holes are provided on both the lifting plate 13 and the lower pressing plate 10 to improve air permeability and further reduce the overall weight of the device.
[0031] In this embodiment, the cross-sectional shape of the connecting plate 30 is arc-shaped, and the center of the arc is on the axis of the circular ring formed by the slider 5 and the two clamping plates 6; the base 3 further includes an angle positioning component; the angle positioning component includes a bottom plate 15, a vertical column 32 and a guide block 33; the bottom plate 15 is placed below the base 3; the vertical column 32 is vertically fixed on the bottom plate 15; the guide block 33 is fixed on one side of the vertical column 32; an arc-shaped chute 39 is provided on one side of the bottom plate 15, and the guide block 33 is movably placed in the arc-shaped chute 39; the height of the arc-shaped chute 39 is greater than the height of the guide block 33; the axis of the arc-shaped chute 39 coincides with the axis of the circular ring formed by the two clamping plates 6; a first anti-slip sheet 34 is fixedly arranged at the upper end of the guide block 33, and a second anti-slip sheet 35 is fixedly arranged in the arc-shaped chute 39; the lower end surface of the second anti-slip sheet 35 is in frictional contact with the upper end surface of the first anti-slip sheet 34; a guide vertical plate 31 is fixedly arranged on the upper end surface of the bottom plate 15, and a guide groove 40 matching the guide vertical plate 31 is arranged on the lower end surface of the bottom plate 15; the upper end of the guide vertical plate 31 is movably inserted into the guide groove 40. When the patient uses the device to fix the arm and is in a standing state, under the action of gravity, the lower end surface of the guide block 33 is in sliding contact with the arc-shaped chute 39, so that the guide block 33 can slide along the arc-shaped chute 39 in the arc-shaped chute 39, keeping the bottom plate 15 always in the directly below position. When the patient lies down, the bottom plate 15 can contact the bed surface in a horizontal state. At this time, the first anti-slip sheet 34 and the second anti-slip sheet 35 are in frictional contact, keeping the connecting plate 30 and the guide block 33 in a relatively fixed state, so that the patient's arm is fixed on the bed surface and will not swing randomly due to the bumps during transportation, aggravating the pain; the setting of the angle positioning component can meet the multi-angle lying requirements of the patient. Compared with the traditional clamping plate 6 fixation, the clamping plate 6 can only fit the bed surface at a specific angle, and this angle may not be suitable for the placement of the patient's arm, while the angle positioning component can meet the multi-angle fixation and lying requirements of the patient.
[0032] In this embodiment, a through hole is provided inside the guide rod 18; the adjustment hole 4 communicates with the through hole; the extension line of the axis of the adjustment hole 4 perpendicularly passes through the axis of the through hole; there are multiple adjustment holes 4; the multiple adjustment holes 4 are arranged in an equally spaced array along the axial direction of the guide rod 18; the distance adjustment unit 2 includes a pull plate 16 and two adjustment rods 28; one end of the adjustment rod 28 is fixed on the pull plate 16; the two adjustment rods 28 are respectively slidably inserted into the through holes of the two guide rods 18; multiple locking holes 29 corresponding to the adjustment holes 4 are provided on the adjustment rod 28; blind holes corresponding to the adjustment holes 4 are provided inside the boss 17, and a spring 26 and a ball head 27 are provided inside the blind holes; the upper end of the spring 26 is fixedly connected to the boss 17, and the lower end is fixedly connected to the ball head 27; the spring 26 pushes the ball head 27 to pass through the adjustment hole 4 and be clamped in the locking hole 29; when the ball head 27 is clamped in the locking hole 29, the center of the ball of the ball head 27 is located inside the adjustment hole 4; when the pull plate 16 is pulled to move the adjustment rod 28 to the outside of the through hole and the adjustment hole 4 and the locking hole 29 are misaligned, the center of the ball of the ball head 27 is located outside the adjustment hole 4. When the axes of the adjustment hole 4 and the locking hole 29 coincide, the ball head 27 is clamped in the locking hole 29, and the guide rod 18 and the adjustment rod 28 are locked by the ball head 27, and the clamping unit 1 is fixed on the base 3. When the adjustment rod 28 is pulled out a certain distance so that the adjustment hole 4 and the locking hole 29 do not correspond, at this time, a small part of the lower end of the ball head 27 is located inside the adjustment hole 4. When the slider 5 is slid, the ball head 27 retracts into the blind hole of the boss 17, facilitating the adjustment of the position of the clamping unit 1.
[0033] In this embodiment, a first handle is fixedly provided on the side of the pull plate 16 away from the adjustment rod 28.
[0034] In this embodiment, a first magnet block 38 is fixedly provided on one of the clamping plates 6; a second magnet block matched with the first magnet block 38 is provided on the other clamping plate 6; the first magnet block 38 and the second magnet block are attracted to each other.
[0035] In this embodiment, an observation port is provided on the clamping plate 6, and the observation port is located on the sides of the vertical adjuster 9 and the horizontal adjuster 12. The observation port can reduce the overall weight of the device, facilitate observing the patient's arm, and facilitate rotating and adjusting the first nut 25 and the second nut 21.
[0036] Usage method Adjust the position of the clamping unit 1: Pull the pull plate 16 to misalign the locking hole 29 of the adjustment rod 28 with the adjustment hole 4 of the guide rod 18 to release the lock.
[0037] Slide the two clamping units 1 along the guide rod 18 so that they are respectively aligned with the patient's wrist and elbow positions.
[0038] Push the pull plate 16 back, and the spring 26 pushes the ball head 27 to snap into the locking hole 29 to complete the position fixation.
[0039] Place the arm and fix it: Place the patient's arm on the lifting plate 13 of the slider 5. The arm naturally presses down on the traction belt 11, and the traction belt 11 pulls the two splints 6 inward to close.
[0040] Rotate the lock catch 7 and snap it into the lock groove 8 to fasten and fix the two splints 6.

[0043] Angle adjustment (when lying down): When the patient stands, the angle positioning component automatically keeps the bottom plate 15 vertically downward.
[0044] When lying down, the bottom plate 15 contacts the bed surface, and the guide block 33 slides in the arc-shaped chute 39 to make the arm angle naturally adapt to the body position, and the anti-slip sheet ensures stable fixation.
[0045] Observation and fine-tuning: Check the arm fixation situation through the observation port on the splint 6, and adjust the fastening component if necessary.
[0046] When it is necessary to release the fixation, open the lock catch 7, and the splint 6 will automatically spring open, and the arm can be taken out.
[0047] The operation of the present invention is simple and the fixation is reliable, which can effectively solve the deficiencies of the traditional dressing method and is applicable to first aid and daily medical scenarios.
