[0002] In long-term clinical practice, when mentally ill patients are restrained on their elbows, they are usually restrained with restraint belts to restrict their elbow mobility, so as to prevent their hands from pulling out the infusion tube or gas tube that is being infused and affecting the treatment. However, the existing restraint belts can easily cause damage to the patient's elbow or wrist, causing pain to the patient and increasing the workload of medical staff. Therefore, being able to effectively restrain the patient's elbow without restricting the elbow's mobility has become the development direction of modern medicine. Utility Model Content

[0003] The utility model aims to provide a medical elbow restraint device, which can better restrain the bending degree of the elbow and can also adjust the bending degree of the elbow as needed, thereby preventing the hand from pulling out the infusion tube or gas tube that is being infused and affecting the treatment.

[0004] In order to solve the above technical problems, the utility model adopts the following solutions:

[0005] A medical elbow restraint device comprises a soft restraint sleeve for inserting the patient's elbow and an adjusting device for adjusting the degree of elbow bending, the restraint sleeve comprises a first restraint part adapted to the arm and a second restraint part adapted to the hand bar, the adjusting device comprises a first fixing seat, a second fixing seat and a limiting rod, the first fixing seat is fixed to the surface of the first restraint part, the second fixing seat is fixed to the surface of the second restraint part, one end of the limiting rod is hinged to the second fixing seat, and the other end is hinged with a slider, the slider is slidably connected to the first fixing seat and can slide along the length direction of the arm, and the first fixing seat is detachably connected with a limiting plate for limiting the displacement range of the slider.

[0006] Due to the adoption of the above technical solution, the medical elbow restraint is a medical device mainly used to limit the patient's elbow movement.

[0029] Example

[0030] A medical elbow restraint device comprises a soft restraint sleeve 1 for inserting the patient's elbow and an adjusting device for adjusting the degree of elbow bending, the restraint sleeve 1 comprises a first restraint portion 101 adapted to the arm 11, and a second restraint portion 102 adapted to the hand lever 3, the adjusting device comprises a first fixed seat 8, a second fixed seat 5 and a limiting rod 6, the first fixed seat 8 is fixed to the surface of the first restraint portion 101, the second fixed seat 5 is fixed to the surface of the second restraint portion 102, one end of the limiting rod 6 is hinged to the second fixed seat 5, and the other end is hinged to a slider 7, the slider 7 is slidably connected to the first fixed seat 8 and can slide along the length direction of the arm 11, and the first fixed seat 8 is detachably connected to a limiting plate 9 for limiting the displacement range of the slider 7.

[0031] In this embodiment, the medical elbow restraint device is a medical device mainly used to limit the patient's elbow movement. This device is particularly suitable for medical scenarios that require elbow fixation, such as post-operative rehabilitation, treatment of certain neurological diseases, etc. The device is designed to ensure that the patient does not over-move the elbow during involuntary movement or treatment, thereby avoiding possible injury or reduced treatment effect.

[0032] Specifically, if Figure 1As shown, the medical elbow restraint device mainly includes two parts: a soft restraint sleeve 1 and an adjustment device. The soft restraint sleeve 1 is the main part of the device, which is divided into a first restraint portion 101 adapted to the arm 11 and a second restraint portion 102 adapted to the hand bar 3. The hand bar 3 refers to the part connected to the shoulder, and the arm 11 refers to the part connected to the palm. This design can ensure that the device can fit the patient's arm 11 and elbow tightly and provide sufficient support and stability. At the same time, the use of soft materials also ensures the comfort of the device and avoids causing unnecessary pressure or discomfort to the patient. A zipper can be set on the side of the restraint sleeve 1, which is more convenient to put it on the patient's arm 11 and hand bar 3.

[0033] like Figure 2 As shown, the adjustment device is used to adjust the bending degree of the elbow. It mainly includes a first fixed seat 8, a second fixed seat 5 and a limiting rod 6. The first fixed seat 8 is fixed to the surface of the first constraint part 101, and the second fixed seat 5 is fixed to the surface of the second constraint part 102. The first fixed seat 8 and the second fixed seat 5 are both located within the plane range where the palm is located, so that the stability between the adjustment device and the constraint sleeve 1 can be ensured. One end of the limiting rod 6 is hinged to the second fixed seat 5, and the other end is hinged with a slider 7. The slider 7 is slidably connected to the first fixed seat 8 and can slide along the length direction of the arm 11. In this way, the bending degree of the elbow can be adjusted by adjusting the sliding displacement of the slider 7. The greater the sliding displacement of the slider 7 in the direction of the fingers, the greater the bending degree of the elbow, and vice versa. A detachable limiting plate 9 is also provided on the first fixed seat 8 to limit the displacement range of the slider 7. When the slider 7 slides to contact with the limiting plate 9, the limiting rod 6 can limit the arm 11 from continuing to rotate toward the hand lever 3, thereby limiting the bending angle of the elbow, thereby ensuring that the elbow moves within the set range.

[0034] In summary, the medical elbow restraint device is a very practical medical device. It can effectively limit the patient's elbow movement through the use of a soft restraint sleeve 1 and an adjustment device, thereby preventing the hand from pulling out the infusion tube or gas tube that is being infused and affecting the treatment, thereby improving the treatment effect. At the same time, its humanized design also ensures the patient's comfort.

[0035] Optionally, a slide groove 12 is provided on the top surface of the first fixed seat 8 along its length direction. The cross-section of the slide groove 12 is dovetail-shaped. Both ends of the slide groove 12 do not pass through the first fixed seat 8. The slider 7 is adapted to the slide groove 12. The limit plate 9 spans the dovetail slide groove 12 and is fixed to the top surface of the first fixed seat 8 at both ends by screws. The top surface of the slider 7 is higher than the top surface of the limit plate 9.

[0036] Specifically, Figure 3As shown, in the design of the first fixed seat 8, the slide groove 12 is a key component. The slide groove 12 is arranged along the length direction of the first fixed seat 8. The length direction of the first fixed seat 8 is the same as the length direction of the arm 11, and its cross-sectional shape is dovetail-shaped. This dovetail-shaped design can effectively prevent the slider 7 from disengaging from the slide groove 12 during the sliding process, thereby ensuring the stability and safety of the device. In addition, the two ends of the slide groove 12 do not pass through the first fixed seat 8, which means that the slider 7 can only move inside the slide groove 12, further enhancing the stability of the device.

[0037] The slider 7 is adaptable to the slide groove 12, which means that the slider 7 can slide smoothly in the slide groove 12. When the elbow is bent, the slider 7 can slide in the slide groove 12, and the sliding displacement determines the degree of elbow bending.

[0038] The limit plate 9 is another important component, which spans the dovetail slot 12 and is fixed to the top surface of the first fixed seat 8 at both ends by screws. The function of the limit plate 9 is to limit the displacement range of the slider 7, thereby ensuring that the elbow moves within the set range. This design can effectively prevent the slider 7 from moving excessively, avoiding unnecessary pressure or injury to the patient.

[0039] It is worth noting that the top surface of the slider 7 is higher than the top surface of the limit plate 9. This design ensures that when the slider 7 moves to the position of the limit plate 9, the top surface of the slider 7 will still be higher than the top surface of the limit plate 9, thereby providing an obvious visual indication, allowing the user to clearly know that the slider 7 has reached its maximum or minimum displacement position. This design improves the convenience and safety of the device.

[0040] In summary, the design of the first fixing seat 8 includes multiple components such as a dovetail slide groove 12, an adaptive slider 7, a limit plate 9 and a screw fixing structure. These components work together to enable the device to effectively limit the patient's elbow movement, improve the treatment effect, and ensure the patient's comfort and safety.

[0041] Optionally, a plurality of connection holes are provided on the top surface of the first fixing seat 8 along its length direction, each connection hole group includes two threaded holes 13 located on both sides of the slide groove 12, and through holes 14 corresponding to the threaded holes 13 are provided at both ends of the limiting plate 9.

[0042] Specifically, Figure 4 As shown, on the top surface of the first fixing seat 8, a plurality of connection holes are provided along its length direction, which are designed for fixed connection with the limiting plate 9. Each connection hole group includes two threaded holes 13 located on both sides of the slide groove 12. The two threaded holes 13 are symmetrically distributed on both sides of the slide groove 12 to ensure that the limiting plate 9 can be firmly fixed on the first fixing seat 8. Figure 5As shown, both ends of the limit plate 9 are provided with through holes 14 corresponding to these threaded holes 13. When the limit plate 9 needs to be fixed, the screw can be passed through the through hole 14 on the limit plate 9 and then screwed into the threaded hole 13 on the first fixing seat 8, so as to achieve a fixed connection between the limit plate 9 and the first fixing seat 8. This connection method is simple and reliable, and can effectively ensure that the limit plate 9 will not loosen or fall off during use. Through the design of multiple groups of connecting holes, the limit plate 9 can be fixed at different positions on the first fixing seat 8 to accommodate patients with different arm 11 lengths. At the same time, the sliding displacement length of the slider 7 can be limited to control the elbow bending angle. This design improves the flexibility and applicability of the device, so that the device can better adapt to the needs of different users.

[0043] In summary, the multiple groups of connection holes and the limit plate 9 on the first fixed seat 8 are designed to achieve a stable connection between the limit plate 9 and the first fixed seat 8. This design is simple and practical, and can effectively ensure the stability and safety of the device during use.

[0044] Optionally, the inner wall of the slide groove 12 is provided with a wear-resistant layer made of polytetrafluoroethylene.

[0045] Specifically, it is a very important design consideration to set a wear-resistant layer made of polytetrafluoroethylene (PTFE) on the inner wall of the slide 12. Polytetrafluoroethylene is a high-performance plastic material, which is famous for its excellent wear resistance, slip resistance and self-lubricating properties. The use of a polytetrafluoroethylene wear-resistant layer in the slide 12, which is often subjected to friction and wear, can significantly reduce the friction coefficient between the slider 7 and the slide 12, thereby reducing wear and friction heat. The presence of the wear-resistant layer can not only extend the service life of the slide 12 and reduce faults or failures caused by wear, but also ensure that the slider 7 moves smoothly in the slide 12 without jamming or hysteresis, which is crucial to maintaining the normal operation of the medical elbow restraint device and the patient's comfortable experience. In addition, polytetrafluoroethylene also has good chemical stability and can resist the erosion of a variety of chemical substances. Therefore, it is very safe and reliable to use in a medical environment. At the same time, it has good biocompatibility and will not cause adverse effects on patients.

[0046] Optionally, when the arm 11 and the handle 3 are straightened, the slider 7 is located at the end of the slide slot 12 adjacent to the handle 3 .

[0047] Specifically, Figure 1As shown, when the arm 11 and the hand bar 3 are in a straight state, the slider 7 should be located at the end of the slide slot 12 adjacent to the hand bar 3. This design is based on ergonomic and medical principles to ensure that the device can provide appropriate support and stability when the patient's arm 11 is straight. The slider 7 is located at the end of the slide slot 12 adjacent to the hand bar 3, which also means that when the patient needs to bend his elbow, it can be achieved by adjusting the position of the slider 7. This design provides flexibility, allowing the patient to bend and stretch his elbow as needed to adapt to different activity requirements.

[0048] Optionally, when the slider 7 slides to the maximum displacement in the slide groove 12, the limit rod 6 can prevent the elbow from bending so that the fingers reach the mouth. The maximum displacement is the end of the slide groove 12 away from the elbow.

[0049] Specifically, when the slider 7 slides to the maximum displacement in the slide groove 12, the design of the limit rod 6 has the important function of preventing excessive bending of the elbow. This design is mainly to ensure that when the patient uses the medical elbow restraint device, the bending degree of the elbow will not reach a position that may cause the fingers to touch the mouth, thereby avoiding potential risks and discomfort. When the slider 7 slides to the end of the slide groove 12 away from the elbow, the limit rod 6 will form a certain angle with the second fixing seat 5. This angle limits the further bending of the elbow. In this way, even if the patient tries to bend the elbow, due to the limiting effect of the limit rod 6, the bending degree of the elbow will be controlled within a safe range, thereby preventing the fingers from touching the mouth. This design not only takes into account the functionality of the device, but also fully considers the comfort and safety of the patient. By limiting the bending degree of the elbow, discomfort or potential risks caused by excessive bending can be avoided, and the stability and reliability of the device during use are also ensured. In summary, when the slider 7 slides to the maximum displacement in the slide groove 12, the limit rod 6 is designed to prevent excessive bending of the elbow and ensure the comfort and safety of the patient. This design embodies the humanization and practicality of the medical elbow restraint device.

[0050] Optionally, the first constraint portion 101 and the second constraint portion 102 are integrally formed and connected.

[0051] Optionally, a cavity 2 for allowing an elbow to pass through is provided at the connection between the first restraint portion 101 and the second restraint portion 102 .

[0052] Specifically, the first constraint portion 101 and the second constraint portion 102 are integrally formed and connected. This design can ensure the integrity and stability of the constraint sleeve 1, improve the durability and service life of the device, and the integrally formed connection avoids the looseness or wear problems that may occur at the seams or connections between different components, thereby reducing the frequency and cost of device maintenance.

[0053] In addition, in order to increase the comfort and functionality of the device, a cavity 2 allowing the elbow to pass through is provided at the connection between the first restraint portion 101 and the second restraint portion 102. The design of this cavity 2 allows the elbow to move freely in the restraint sleeve 1 without being subjected to excessive compression or restriction. The presence of the cavity 2 not only improves the comfort of the device, but also allows the patient to perform moderate elbow bending when necessary to meet different activity requirements.

[0054] To sum up, the first restraint part 101 and the second restraint part 102 are integrally connected, and a cavity 2 for allowing the elbow to pass through is provided at the connection. This design not only enhances the integrity and stability of the device, but also improves the patient's comfort and freedom of movement. Such a design makes the medical elbow restraint device more ergonomic and medical requirements, and provides patients with a better user experience.

[0055] Optionally, a plurality of exhaust holes 4 are provided on the surface of the restraint sleeve 1 .

[0056] Optionally, a sweat-absorbing layer 10 is provided on the inner wall of the restraint sleeve 1 .

[0057] Specifically, Figure 1 As shown, in the design of the medical elbow restraint device, in order to improve the patient's comfort and reduce discomfort, some additional design measures can be taken, among which the exhaust holes 4 on the surface of the restraint sleeve 1 and the sweat-absorbing layer 10 on the inner wall are two optional design schemes. First, a plurality of exhaust holes 4 are provided on the surface of the restraint sleeve 1. These exhaust holes 4 can effectively promote air circulation and reduce the dampness and stuffiness inside the restraint sleeve 1. Especially in hot weather or when the patient sweats a lot, the role of the exhaust holes 4 is more obvious. By discharging excess heat and moisture, the exhaust holes 4 can keep the inside of the restraint sleeve 1 dry and comfortable, reducing the patient's discomfort.

[0058] In addition, it is also a practical design choice to provide a sweat-absorbing layer 10 on the inner wall of the restraint sleeve 1. The sweat-absorbing layer 10 is usually made of a material with good hygroscopicity and can effectively absorb the sweat produced by the patient when sweating. In this way, the sweat will not stay inside the restraint sleeve 1, but will be quickly absorbed and discharged by the sweat-absorbing layer 10, thereby keeping the inside of the restraint sleeve 1 dry and clean. The design of the sweat-absorbing layer 10 not only improves the patient's comfort, but also reduces the bacterial growth and odor problems caused by sweat accumulation.

[0059] In summary, the exhaust holes 4 on the surface of the restraint sleeve 1 and the sweat-absorbing layer 10 on the inner wall are both optional solutions designed to improve the patient's comfort and reduce discomfort. These design measures can effectively promote air circulation, discharge excess heat and moisture, and absorb sweat, thereby keeping the inside of the restraint sleeve 1 dry and comfortable. Such a design makes the medical elbow restraint device more ergonomic and medical, and provides patients with a better user experience.

[0060] The above is only a preferred embodiment of the utility model and does not limit the utility model in any form. According to the technical essence of the utility model, within the spirit and principles of the utility model, any simple modification, equivalent replacement and improvement made to the above embodiment still falls within the protection scope of the technical solution of the utility model.
