Description

Technical Field

[0001] The invention relates to the technical field of restraint belts, in particular to a limb fall prevention restraint belt in a resuscitation room. Background Art

[0002] The recovery room, also known as the post-anesthesia monitoring and treatment room, is simply a place to ensure that patients safely pass through the anesthesia recovery period. In the anesthesia recovery room, professional personnel monitor and treat patients who have not awakened after general anesthesia, and patients who have awakened but are not yet stable. Some patients need to use restraints after surgery. The restraint is a safety device to protect patients. It is used to limit the body and limb movements of agitated patients who are in danger of self-injury or falling out of bed, and when treatment requires fixing a certain part of the body.

[0003] At present, when traditional limb anti-fall restraint belts are used to restrain patients' limbs, in order to avoid wound injuries caused by patient activities, the movement of patients' limbs is restricted. Long-term fixation will lead to muscle disuse, which in turn causes muscle atrophy, and will also lead to obstructed blood circulation and increase the risk of thrombosis. At the same time, long-term fixation will also cause psychological discomfort to patients. When patients are allowed to move their limbs, they are prone to excessive range of motion, resulting in accidental injuries or aggravation of existing injuries. In addition, patients move differently when they are awake and unconscious, and the restraints need to be adjusted according to different states. Frequent removal and re-wearing of the restraint belt will increase patients' discomfort and increase the workload of medical staff, which makes the equipment less practical.

[0015] Compared with the prior art, the advantages of the present invention are: 1. The present invention realizes flexible switching of restraint modes by utilizing the adsorption effect of magnetic blocks and magnets, combined with a movable transmission block and an electric telescopic rod. When the patient is not awake, a restraint mode of connecting two hands and two feet is adopted, which relatively gently restricts the patient's movement, while avoiding the discomfort caused by excessive restraint, helping to maintain blood circulation and muscle vitality, preventing the patient from accidentally touching or uncovering the wound dressing with his hands, and restricting the patient's leg movement, helping to maintain the patient's body position stability. After the patient wakes up, it is converted to cross restraint, with the left hand connected to the right foot and the right hand connected to the left foot, which more effectively restricts the patient's turning over and large movements, ensures the patient's safety and reduces the risk of accidents, and allows medical staff or the patient's family to easily adjust the connection mode of the restraint belt according to the patient's physical condition and specific needs, without the need to frequently remove and re-wear, reducing the patient's discomfort, thereby enhancing the practicality of the device.

[0016] 2. The present invention increases the surface roughness of the third restraint and the contact area with the skin by setting the edge of the third restraint to be wavy, so that the restraint fits the skin more tightly, reduces the possibility of gaps and sliding, and helps to prevent the restraint from slipping or loosening when the patient struggles or moves. The contact part of the third restraint with the patient's limbs is provided with a silicone sheet. The silicone sheet has buffering properties and can absorb and disperse impact force when the limbs are subjected to external force, thereby reducing the pressure on the joints and soft tissues. In addition, the silicone sheet can maintain good fit when the skin is moist or sweating, and during the struggle, the friction between the skin and the silicone sheet allows the third restraint to fit the skin more closely.

[0017] 3. The present invention drives the transmission rod and the connecting rod by the movement of the first moving block and other components. The baffle blocks the first restraint belt from moving to the outside of the shell, so that the connecting rod only drives the first restraint belt to tighten the waist, ensuring that the waist is centrally restrained and no unnecessary pressure is caused on other parts of the patient, thereby reducing the overall restraint pressure on the patient, especially on parts that are prone to discomfort such as the shoulders and chest, thereby improving the patient's comfort. The waist is an important supporting part of the human body. Waist restraint can more effectively prevent the patient from moving in an unconscious state and reduce the risk of falling or other accidental injuries.

[0018] 4. The present invention arranges the first rubber ball in the second arc plate and the second rubber ball in the fixing device. When the first restraint belt moves, it will drive the second rubber ball, and when the second connecting belt moves, it will drive the first rubber ball. The rubber ball, as an elastic element, can absorb and disperse the impact force, thereby slowing down the movement speed of the restraint belt and reducing the potential impact on the patient's wound. The design of the arc groove enables the rubber ball to move toward the narrow end when subjected to tension, thereby gradually increasing the squeezing force on the restraint belt and ensuring that the patient's movement is carried out within a safe range. Through the squeezing effect of the rubber ball, the restraint belt will be subject to additional resistance during the movement, which helps to maintain the stability and reliability of the restraint belt and prevent excessive sliding due to external force, thereby facilitating the healing of the wound.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figures 1 to 11The limb anti-fall restraint belt in the resuscitation room includes a second restraint belt 5, a restraining mechanism and a fixing mechanism. The second restraint belt 5 is located above the bed 1. The second restraint belt 5 is fixedly connected to the fourth restraint belt 14. The fourth restraint belt 14 is provided with a gauze 13. The gauze 13 is provided with an opening. The size of the opening corresponds to the patient's wound, ensuring that the gauze 13 will not cause pressure on the wound when restrained, and can fix the edge of the protective film covering the wound. The width of the second restraint belt 5 is wider than the fourth restraint belt 14, which can provide a wider support area and help reduce the shaking of the lower limbs when moving. and pulling, thereby protecting the wound site from additional damage. The second strap 5 is provided with a first strap 4, the first strap 4 runs through the second strap 5, and is slidably connected to the second strap 5. Two limit blocks 16 are fixedly installed on the first strap 4, and the two limit blocks 16 are symmetrically distributed on both sides of the second strap 5. The function of the limit blocks 16 is to limit the sliding range of the second strap 5 relative to the first strap 4, and prevent the second strap 5 from excessively sliding due to external force, thereby ensuring the stability and reliability of the second strap 5, and ensuring that a certain amount of movement space is given to the patient. At the same time, it can prevent the patient from moving significantly and causing damage to the wound. The limit block 16 can also be used as a reference point for adjusting and fixing the position of the second restraint belt 5. The best restraint strength and position can be determined by sliding the second restraint belt 5 and observing the position of the limit block 16. The two ends of the first restraint belt 4 are respectively penetrated by a fixing device 3 that is slidably connected. The two limit blocks 16 are located between the two fixing devices 3. The two fixing devices 3 are symmetrically distributed on both sides of the bed 1 and are connected to the bed 1. The fixing device 3 is provided with a first arc groove inside, and a second rubber ball 17 is provided in the first arc groove. The first restraint belt 4 contacts the second rubber ball 17, and the width of the first arc-shaped groove gradually decreases from the middle to both ends. The first restraint belt 4 moves under the pulling force of the patient, so that the second rubber ball 17 moves toward the narrow end of the first arc-shaped groove, so that the squeezing force of the second rubber ball 17 on the first restraint belt 4 gradually increases, and the difficulty of moving the first restraint belt 4 increases, thereby slowing down the moving speed of the first restraint belt 4, controlling the moving range of the first restraint belt 4, ensuring that the patient's movement is carried out within a safe range, and avoiding the risks of wound compression, tearing or infection caused by excessive movement.

[0023] The restraint mechanism includes four groups of restraint components, which are used to restrain the patient's limbs. The restraint components include a first arc plate 8, a second arc plate 11, and a second connecting belt 7. The first arc plate 8 and the second arc plate 11 form a cylindrical shape, which is used to install the restraint components on the guardrail of the bed 1. The second connecting belt 7 runs through the first arc plate 8. The second arc plate 11 is provided with a second arc groove inside. The second arc groove is provided with a first rubber ball 12. The width of the second arc groove gradually decreases from the middle to both sides. The second connecting belt 7 is in contact with the first rubber ball 12 (such as Figure 3As shown in the figure, the two ends of the second connecting belt 7 are fixedly connected with the first connecting belt 2 and the third restraining belt 9 respectively. The end of the first connecting belt 2 away from the first arc plate 8 is fixedly installed with a spring buckle 6. When the first rubber ball 12 is pulled toward the narrow end of the second arc groove by the force of the second connecting belt 7, the first rubber ball 12 gradually squeezes the second connecting belt 7 close to the guardrail, increasing the movement resistance of the second connecting belt 7, which can better limit the movement range of the second connecting belt 7, ensure that the patient's movement is carried out within a safe range, and prevent the risks of wound compression, tearing or infection caused by excessive movement. The first rubber ball 12 can be deformed when the patient moves to absorb part of the second connecting belt 7. The third restraint belt 9 can reduce the impact force, slow down the movement speed of the third restraint belt 9, and reduce the potential impact on the wound. The edge of the third restraint belt 9 is set to a wavy shape, which increases the contact area and roughness of the third restraint belt 9 with the skin, reduces gaps and sliding, and prevents the third restraint belt 9 from slipping or loosening when the patient struggles or moves, thereby ensuring the safety of the patient. A silicone sheet 10 is set on the inner side of the third restraint belt 9. The addition of the silicone sheet 10 provides a cushioning performance, reduces the impact force when the limbs are subjected to external force, reduces the pressure on the joints and soft tissues, and improves the comfort of the patient. The silicone sheet 10 can also maintain good fit when the skin is moist or sweating, thereby enhancing the durability and stability of the restraint belt.

[0024] The fixing mechanism is located below the bed 1, and the fixing mechanism includes a shell 22, and the shell 22 is located between the two fixing devices 3. The two ends of the first restraint belt 4 are respectively connected to the shell 22 through a connecting assembly. A suction cup 15 is fixedly installed on the top of the shell 22, and the suction cup 15 is used to fix the shell 22 to the bottom of the bed 1. A limiting cylinder 28 is fixedly installed on the inner wall of the shell 22. A transmission block 18 is slidably connected to the bottom of the shell 22. The transmission block 18 is slidably connected to the limiting cylinder 28. A handle 19 is fixedly installed on the bottom of the transmission block 18. A block assembly is provided on the top of the transmission block 18. The block assembly is located in the limiting cylinder 28. The block assembly includes a fixed A first clamping block 34 is fixedly installed on the top of the transmission block 18, a second clamping block 35 is fixedly installed on the top of the first clamping block 34, a third clamping block 36 is fixedly installed on the top of the second clamping block 35, and a fourth clamping block 37 is fixedly installed on the top of the third clamping block 36. The first clamping block 34, the second clamping block 35, the third clamping block 36 and the fourth clamping block 37 are slidably connected with the limiting cylinder 28. A fastener 25 is provided on the outer wall of the transmission block 18, and the fastener 25 is fixedly installed on the bottom of the shell 22. The transmission block 18 is pushed by the handle 19 to drive the clamping block assembly to move along the inner wall of the limiting cylinder 28. The position of the transmission block 18 can be fixed by starting the fastener 25.

[0025] The side wall of the limiting cylinder 28 is provided with four shift grooves, and the four shift grooves are distributed in a circular array on the side wall of the limiting cylinder 28. The first clamping block 34, the second clamping block 35, the third clamping block 36 and the fourth clamping block 37 are respectively penetrated by the third connecting belt 27 for sliding connection, and the two ends of the third connecting belt 27 respectively penetrate the shift grooves on the corresponding sides. The third connecting belt 27 on the first clamping block 34 and the second clamping block 35 is a straight line, and the third connecting belt 27 on the first clamping block 34 and the second clamping block 35 forms a cross structure. The third connecting belt 27 on the third clamping block 36 and the fourth clamping block 37 is a right angle type, and the third connecting belt 27 on the third clamping block 36 and the fourth clamping block 37 forms a cross structure. The two cross structures formed by the third connecting belts 27 are aligned, and the two ends of the four third connecting belts 27 are respectively fixedly connected with magnetic blocks 26. The side wall of the transmission block 18 is fixedly installed with four connecting plates 21. The four connecting plates 21 are distributed in a circular array on the side wall of the transmission block 18. The four connecting plates 21 are located outside the shell 22. The ends of the four connecting plates 21 away from the transmission block 18 are respectively fixedly connected with electric telescopic rods 20. The electric telescopic rods 20 penetrate the shell 22 and are slidably connected to the shell 22. The four electric telescopic rods 20 correspond to the two magnetic blocks 26 respectively. The side wall of the electric telescopic rod 20 is fixedly installed with an electromagnet 32. The electromagnet 32 ​​is energized to adsorb the corresponding magnetic block 26.

[0026] The housing 22 is provided with a first moving block 23, a second moving block 24, a third moving block 30 and a fourth moving block 31, and the four groups of restraint components correspond to the first moving block 23, the second moving block 24, the third moving block 30 and the fourth moving block 31 respectively. The first connecting belt 2 in the restraint component is connected to the corresponding moving block by using a spring buckle 6. The first moving block 23, the second moving block 24, the third moving block 30 and the fourth moving block 31 are distributed in a circular array on the side wall of the housing 22 and correspond to the four electric telescopic rods 20 respectively. The outer wall of the limiting cylinder 28 is provided with four groups of limiting components, and the four groups of limiting components correspond to the first moving block 23, the second moving block 24, the third moving block 30 and the fourth moving block 31 respectively. The limiting components include fixedly mounted The two limit plates 29 on the side wall of the limit cylinder 28 are symmetrically distributed on both sides of the moving blocks on the corresponding sides, so that the first moving block 23, the second moving block 24, the third moving block 30 and the fourth moving block 31 slide along the side where the two limit plates 19 are close to each other when pulled, and the first moving block 23, the second moving block 24, the third moving block 30 and the fourth moving block 31 are respectively provided with receiving grooves, and the receiving grooves are used to receive the magnetic blocks 26 on the corresponding sides. Magnets 40 are fixedly installed in the receiving grooves of the first moving block 23, the second moving block 24, the third moving block 30 and the fourth moving block 31, and a fastener 25 is fixedly installed on the bottom of the outer shell 22. The fastener 25 is arranged on the outer wall of the transmission block 18 to fix the position of the transmission block 18.

[0027] The four groups of restraint components are connected to the first moving block 23, the second moving block 24, the third moving block 30 and the fourth moving block 31 respectively through the spring buckle 6. When the patient is not awake, the transmission block 18 is pushed to move toward the inside of the shell 22 through the handle 19, and the magnetic block 26 corresponding to the third clamping block 36 and the fourth clamping block 37 is embedded into the first moving block 23, the second moving block 24, the third moving block 30 and the fourth moving block 31 through the electric telescopic rod 20 and is adsorbed and fixed by the magnet 40. Then the electromagnet 32 ​​is disconnected, the electric telescopic rod 20 retracts, and the fastener 25 fixes the transmission block 18. Since the third connecting belt 27 on the third clamping block 36 and the fourth clamping block 37 is a right angle type, the patient's two hands are connected to the same connecting belt, and the two legs are connected to the same connecting belt, ensuring that the patient is basically fixed in an unconscious state to prevent possible injuries or displacement due to unconscious movements. When the patient just wakes up, the transmission block 18 is moved, and the electric telescopic rod 20 is started, so that the first clamping block 34 The magnetic blocks 26 corresponding to the second clamping block 35 are embedded in the first moving block 23, the second moving block 24, the third moving block 30 and the fourth moving block 31. After the magnetic blocks 26 corresponding to the third clamping block 36 and the fourth clamping block 37 leave the first moving block 23, the second moving block 24, the third moving block 30 and the fourth moving block 31, they are adsorbed by the magnetic fixing block (not shown in the figure) on the top of the inner wall of the shell 22, so as to avoid the magnetic blocks 26 corresponding to the third clamping block 36 and the fourth clamping block 37 from falling under the influence of gravity after leaving the first moving block 23, the second moving block 24, the third moving block 30 and the fourth moving block 31. Since the third connecting belt 27 on the first clamping block 34 and the second clamping block 35 is linear, the patient's left hand is connected to the right foot with the same connecting belt, and the right hand is connected to the left foot with the same connecting belt, forming a cross-binding effect, which not only maintains the necessary binding to ensure safety, but also allows the patient to perform slight activities in a more natural and comfortable way, which helps to promote body recovery and blood circulation.

[0028] The connecting assembly includes a connecting rod 38 fixedly installed at the end of the first restraint belt 4, and the two ends of the connecting rod 38 are rotatably connected to the transmission rods 39, and the transmission rods 39 are fixedly connected to the moving blocks on the corresponding sides. A baffle 33 is fixedly installed on the first restraint belt 4. When the first moving block 23, the second moving block 24, the third moving block 30, and the fourth moving block 31 move, the corresponding transmission rod 39 will be driven to move, so that the connecting rod 38 drives the first restraint belt 4 to move. The baffle 33 makes the connecting rod 38 only drive the first restraint belt 4 to move toward the inside of the shell 22, tighten the waist, and enhance the overall stability of the body.

[0029] In the present invention, when the patient lies on the bed 1, first, according to the position of the patient, the fixing device 3, the first arc plate 8, and the second arc plate 11 are fixed to the edge of the bed 1, and the outer shell 22 is fixed to the back of the bed 1 with a suction cup 15. Then, according to the position of the patient's abdominal wound, the second binding belt 5 is wrapped around the patient at the position below the wound. After the tightness of the second binding belt 5 is adjusted according to the patient's body shape, an opening is cut on the gauze 13. The size of the opening should ensure that the wound will not be compressed when the gauze 13 is bound, and the edge of the protective film covering the wound can be fixed. Then, the fourth binding belt 14 is slightly tightened. After slightly stretching to both sides, it is fixed from the patient's back. In this process, the fourth strap 14 will also drive the gauze 13 to stretch, so that the gauze 13 fits better with the skin near the wound. The fourth strap 14 is fixed above the wound and is designed to be narrower and fit the skin better. The narrow band design can reduce the sense of restraint while ensuring sufficient pressure, thereby improving the patient's comfort. The width of the second strap 5 is wider than that of the fourth strap 14. The wide strap can provide a wider support area, which helps to reduce the shaking and pulling of the lower limbs when moving, thereby protecting the wound from additional damage. Finally, the first strap 4 passing through the second strap 5 is fixed. This fixation allows the second strap 5 to move slightly on the first strap 4, giving the patient a certain amount of movement space. However, due to the presence of the first strap 4 and the limit block 16, the patient can only perform a small parallel movement and cannot perform large movements such as turning over, which helps prevent the patient from inadvertently pressing on the wound and reducing pain and discomfort.

[0030] After the patient's waist is fixed by the first strap 4, the second strap 5 and the fourth strap 14, the patient's limbs are fixed by the third strap 9. The edge of the third strap 9 is wavy. Compared with the traditional straight or smooth edge, the wavy edge can increase the surface roughness and the contact area with the skin, so that the strap fits the skin more tightly, reducing the possibility of gaps and sliding, and helping to prevent the strap from slipping or loosening when the patient struggles or moves. In addition, the contact part of the third strap 9 with the patient's limbs is equipped with a silicone sheet 10. The silicone sheet 10 has a certain buffering performance and can absorb and disperse the impact force when the limbs are subjected to external force, thereby reducing the pressure on the joints and soft tissues. In addition, the silicone sheet 10 can maintain good fit when the skin is wet or sweating, and during the struggle, due to the friction between the skin and the silicone sheet 10, the third strap 9 can fit the skin more closely. When the patient's limbs or waist move, the multiple first rubber balls 12 and the second rubber balls 17 inside the fixing device 3 and the second arc plate 11 will be pulled or squeezed, and the multiple first rubber balls 12 and the second rubber balls 17 can be deformed to absorb part of the impact force, thereby slowing down the movement speed of the first binding belt 4 and the second connecting belt 7, and reducing the potential impact on the patient's wound. In addition, the first rubber balls 12 and the second rubber balls 17 are inside the fixing device 3 and the second arc plate 11. This limiting effect ensures that the patient's movement is carried out within a safe range, avoiding the risk of wound compression, tearing or infection caused by excessive movement.

[0031] After the patient's waist and limbs are fixed, the first connecting belt 2 corresponding to the third restraint belt 9 on the left hand, right hand, left foot, and right foot is fixed to the first moving block 23, the second moving block 24, the third moving block 30, and the fourth moving block 31 respectively with a spring buckle 6, and then the transmission block 18 is moved by the handle 19, and the magnetic block 26 corresponding to the third clamping block 36 and the fourth clamping block 37 is embedded into the first moving block 23, the second moving block 24, the third moving block 30, and the fourth moving block 31 through the electric telescopic rod 20 and the connecting plate 21, and is adsorbed and fixed by the magnet 40 at the same time, and then the electromagnet 32 ​​is disconnected, the electric telescopic rod 20 is retracted, and the transmission block 18 is fixed with the fastener 25. At this time, the left hand and the right hand, the left foot and the right foot can be connected through the device under the bed 1 through the third connecting belt 27, the third clamping block 36, and the fourth clamping block 37, forming a closed loop, which limits the independent movement of the patient's arms and legs. This situation applies to patients who are not awake, when their movements are usually unconscious, small, and uncoordinated. In this case, connecting the left hand to the right hand and the left foot to the right foot can relatively gently restrict the patient's movement while avoiding the discomfort caused by excessive restraint. This connection method allows patients to move in a small range, which helps maintain blood circulation and muscle activity. This design can also prevent patients from accidentally touching or uncovering wound dressings with their hands, while limiting the movement of the patient's legs, helping to keep the patient's position stable. When patients just wake up, they may try to make larger movements, such as turning over or sitting up. At this time, the transmission block 18 can be moved so that the magnetic block 26 corresponding to the first clamp block 34 and the second clamp block 35 is embedded in the first moving block 23, the second moving block 24, the third moving block 30, and the fourth moving block 31, and the left hand and the right foot, and the right hand and the left foot are connected through the third connecting belt 27, the first clamp block 34, and the second clamp block 35, so as to form a cross-binding effect, which can more effectively limit the patient's turning over and large movements, and is particularly suitable for preventing the patient from making large movements when awake, thereby ensuring the patient's safety and reducing the risk of accidents. This design allows medical staff or the patient's family to easily adjust the connection method of the restraint belt according to the patient's physical condition and specific needs, without the need to frequently remove and re-wear it, reducing the patient's discomfort.

[0032] When the first moving block 23, the second moving block 24, the third moving block 30, and the fourth moving block 31 move, the transmission rod 39 is driven to move, so that the connecting rod 38 drives the first restraint belt 4 to move, and due to the existence of the baffle 33, the connecting rod 38 only drives the first restraint belt 4 to tighten the waist. When the limbs move, the tightening of the waist by the first restraint belt 4 can enhance the overall stability of the body. In addition, the slight tightening of the waist can also disperse the pressure, reduce the burden on the lumbar spine and waist muscles, and help relieve waist discomfort.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
