Abstract
Description
Technical Field
[0001] This utility model relates to the field of restraint technology, and in particular to a restraint device specifically designed for epilepsy patient wards. Background Technology
[0002] During an epileptic seizure, the patient typically experiences involuntary twitching of a specific body part, most commonly one eyelid, corner of the mouth, hand, or toes, but sometimes one side of the face or limbs. In severe cases, the patient may experience transient limb paralysis after the seizure. Some patients may also exhibit abnormal movements related to the body's motor system.
[0003] During treatment, medical staff will use restraint devices to restrain the patient to prevent injury to the patient or others during a seizure. Common restraint devices include straps or restraint belts.
[0004] Existing straps or restraints are all forced restraints, which firmly fix the patient to the bed to make it difficult for the patient to move. Since the patient's limbs will twitch and stiffen during an epileptic seizure, the use of straps or restraints with forced restraints may further damage the patient (such as tissue or joint damage).
[0005] Therefore, this utility model provides a restraint device specifically for epilepsy patient wards to solve the above-mentioned problems. Utility Model Content
[0006] The purpose of this invention is to provide a restraint device specifically designed for epilepsy patients in their wards, in order to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a restraint device for epilepsy patients in a ward, comprising multiple sets of mounting plates and protective pillows symmetrically installed on the bed;
[0008] The feature is that a roller is rotatably mounted on the mounting plate; a telescopic belt is mounted on the roller, and the telescopic belt is wound around the roller;
[0009] The protective pillow is equipped with a fixing strap;
[0010] A snap-fit structure for quick connection or separation is provided between the fixing belt and the telescopic belt;
[0011] The mounting plate is equipped with a recycling structure;
[0012] When the telescopic belt extends and causes the reel to rotate in the forward direction, the recovery structure can cause the reel to rotate in the reverse direction to recover the telescopic belt.
[0013] Preferably, the snap-fit structure includes a connecting sleeve mounted on the telescopic belt, and the connecting sleeve has symmetrically formed limit grooves.
[0014] Preferably, the snap-fit structure further includes a docking block installed on the fixing band. The docking block has symmetrically formed shrinkage slits. After the shrinkage slits are formed on the docking block, two symmetrical docking posts are formed. A limiting block that snaps into the limiting groove is installed on the docking post.
[0015] Preferably, the recycling structure includes a motor mounted on the mounting plate, a fixed turntable mounted on the output end of the motor, a sliding turntable slidably fitted on the reel, a plurality of first tooth blocks mounted on the sliding turntable, and a plurality of second tooth blocks meshing with the first tooth blocks mounted on the fixed turntable.
[0016] Preferably, the surface on which the second tooth block mates with the first tooth block is set as a plane.
[0017] Preferably, the recycling structure further includes a first gear mounted on the reel, two sets of first rotating shafts symmetrically mounted on the mounting plate, a second gear meshing with the first gear mounted on the first rotating shaft, a spiral groove on the first rotating shaft, a slider slidably mounted on the first rotating shaft, a protruding post slidably fitted with the spiral groove on the slider, a lever cooperating with the sliding turntable on the slider, and multiple sets of guide rods mounted on the mounting plate, with guide sleeves slidably fitted on the guide rods and fixedly connected to the slider.
[0018] Preferably, the two sets of levers are respectively arranged on both sides of the sliding turntable, with the lever closer to the fixed turntable abutting against the sliding turntable, and the other lever being separated from the sliding turntable.
[0019] Preferably, a guide that is fixedly connected to the hospital bed is slidably mounted on the telescopic belt.
[0020] The beneficial effects of this utility model are:
[0021] This invention connects the fixing strap and the telescopic strap through a docking structure, allowing the protective pillow to fit snugly against the patient. The docking structure enables rapid restraint of the patient, and when the patient's condition worsens and transfer is required, the docking structure allows for rapid release of the restraint without affecting treatment efficiency. Because the length of the telescopic strap is not locked during the patient's convulsions (it can extend a certain distance), the restraint device is elastic, allowing the patient to shake and convulse slightly without being forcibly restrained, thus preventing secondary injury to the patient during an attack.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of this utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0050] Example 1, see Figure 1-7 As shown, a restraint device for epilepsy patients in a ward includes multiple sets of mounting plates 1 and protective pillows 16 symmetrically installed on the bed.
[0051] A roller 2 is rotatably mounted on the mounting plate 1; a telescopic belt 14 is mounted on the roller 2 and the telescopic belt 14 is wound around the roller 2.
[0052] The protective pillow 16 is equipped with a fixing strap 18;
[0053] A snap-fit structure for quick connection or separation is provided between the fixed belt 18 and the telescopic belt 14;
[0054] A recycling structure is provided on mounting plate 1;
[0055] When the telescopic belt 14 extends and drives the reel 2 to rotate in the forward direction, the recovery structure can drive the reel 2 to rotate in the reverse direction to recover the telescopic belt 14.
[0056] In this embodiment, when the epilepsy patient lies flat on the hospital bed, the fixing strap 18 and the telescopic strap 14 are connected by a docking structure, so that the protective pillow 16 fits the patient. The docking structure can quickly restrain the patient, and when the patient's condition worsens and transfer is required, the docking structure can quickly release the restraint without affecting the treatment efficiency.
[0057] The protective pillow 16 can increase the contact area between the fixation strap 18 and the patient, thereby improving the patient's comfort and effectively preventing strangulation injuries.
[0058] When the patient shakes or convulses after being restrained, the force generated by the shaking will act on the protective pillow 16, thereby moving the protective pillow 16 away from the hospital bed. During this process, the protective pillow 16 will act on the telescopic belt 14 through the docking structure, thereby pulling the telescopic belt 14 outward and causing the roller 2 to rotate in the forward direction.
[0059] When the telescopic belt 14 extends to a certain length, the roller 2 rotates several times in the forward direction. At this time, the retrieval structure will drive the roller 2 to rotate in the reverse direction to retrieve the telescopic belt 14, thereby moving the protective pillow 16 closer to the hospital bed to reapply restraining force and prevent the patient from sitting up or having large-scale convulsions.
[0060] Because the length of the elastic band 14 is not locked during the patient's convulsions (it can extend a certain distance), that is, the restraint is an elastic restraint, the patient can shake and convulse slightly, and it does not have the function of forced restraint, which can avoid secondary injury to the patient when the disease occurs.
[0061] Example 2: The snap-fit structure includes a connecting sleeve 15 installed on the telescopic belt 14, and the connecting sleeve 15 has symmetrically formed limit grooves 1501.
[0062] In embodiment 3, the snap-fit structure also includes a docking block 17 installed on the fixing belt 18. The docking block 17 has symmetrically opened shrinkage slits 1701. After the shrinkage slits 1701 are opened on the docking block 17, two symmetrical docking posts 1702 are formed. A limiting block 1703 that snaps into the limiting groove 1501 is installed on the docking post 1702.
[0063] In this embodiment, after the patient lies flat on the hospital bed, the protective pillow 16 is placed flat on the patient's body; then the fixing straps 18 on both sides of the protective pillow 16 are connected to the telescopic straps 14 on both sides of the hospital bed.
[0064] Connection process: Insert the docking post 1702 into the connecting sleeve 15; since the maximum distance between the two limiting blocks 1703 is greater than the width of the connecting sleeve 15; and since the docking post 1702 itself has a certain elasticity, the two limiting blocks 1703 will move closer to each other during the insertion process, compressing and shrinking the seam 1701.
[0065] When the limiting block 1703 is inserted into the connecting sleeve 15, the squeezing action of the inner wall of the connecting sleeve 15 on the limiting block 1703 and the elastic force of the docking post 1702 will cause the limiting block 1703 to always be in contact with the connecting sleeve 15.
[0066] When the limiting block 1703 moves into the limiting groove 1501, under the elastic force of the docking post 1702, the two limiting blocks 1703 will move away from each other and enter the limiting groove 1501. The side of the limiting block 1703 near the protective pillow 16 is a straight surface. Through the mutual engagement of the straight surface with the limiting groove 1501, the docking block 17 and the connecting sleeve 15 will not easily separate, thereby ensuring a stable connection between the fixing belt 18 and the telescopic belt 14.
[0067] When separation is required, an external force is applied to the limiting blocks 1703 to bring the two limiting blocks 1703 closer together, thus separating them from the limiting groove 1501. Once the limiting groove 1501 separates from the straight surface, the stable connection between the mating block 17 and the connecting sleeve 15 is released. Then, the mating post 1702 is pulled outwards, thereby separating the mating block 17 from the connecting sleeve 15, and thus separating the fixing belt 18 from the telescopic belt 14.
[0068] The docking structure allows for the rapid restraint of patients, and when a patient's condition worsens and requires transfer, the docking structure allows for the rapid release of restraints without affecting treatment efficiency.
[0069] Example 4: The recycling structure includes a motor 5 mounted on a mounting plate 1, a fixed turntable 6 mounted on the output end of the motor 5, a sliding turntable 4 slidably fitted on the reel 2, a plurality of first tooth blocks 401 mounted on the sliding turntable 4, and a plurality of second tooth blocks 601 meshing with the first tooth blocks 401 mounted on the fixed turntable 6.
[0070] In this embodiment, in the initial state, the sliding turntable 4 and the fixed turntable 6 are separated, and the first tooth block 401 and the second tooth block 601 are not engaged.
[0071] Motor 5 always drives the fixed turntable 6 to rotate in the opposite direction; at this time, the telescopic belt 14 is in the retracted state.
[0072] When the patient has a seizure, the protective pillow 16 will cause the telescopic belt 14 to extend outward, thereby causing the roller 2 to rotate in the forward direction.
[0073] During the forward rotation of the scroll 2, the sliding turntable 4 will gradually approach the fixed turntable 6; and the sliding turntable 4 rotates in the forward direction while the fixed turntable 6 rotates in the reverse direction.
[0074] When the sliding turntable 4 moves to the point where the first tooth block 401 and the second tooth block 601 mesh with each other, the fixed turntable 6 can drive the sliding turntable 4 to rotate in the opposite direction (the kinetic energy of the motor 5 is greater than the kinetic energy that makes the roller 2 rotate in the forward direction).
[0075] When the sliding turntable 4 rotates in the opposite direction, it can drive the roller 2 to rotate in the opposite direction, thereby retracting the telescopic belt 14 and bringing the protective pillow 16 closer to the bed, thus re-restraining the patient and preventing the patient from suddenly sitting up or having large convulsions, thereby avoiding secondary injury to the patient.
[0076] When the fixed turntable 6 drives the sliding turntable 4 to rotate in the opposite direction until the telescopic belt 14 is retracted, the sliding turntable 4 will move away from the fixed turntable 6, thereby causing the first tooth block 401 and the second tooth block 601 to disengage, so that the telescopic belt 14 can be extended again by the patient's movement.
[0077] In Example 5, the surface on which the second tooth block 601 mates with the first tooth block 401 is set as a plane.
[0078] In this embodiment, when the first tooth block 401 and the second tooth block 601 are engaged, the flat surface will abut against the plane, so that the fixed turntable 6 can drive the sliding turntable 4 to rotate in the opposite direction, and there will be no disengagement during the rotation, thereby ensuring the stability of the restraint device.
[0079] Example 6: The recycling structure also includes a first gear 3 mounted on the reel 2, two sets of first rotating shafts 8 symmetrically mounted on the mounting plate 1, a second gear 9 meshing with the first gear 3 mounted on the first rotating shaft 8, a spiral groove 801 opened on the first rotating shaft 8, a slider 10 slidably mounted on the first rotating shaft 8, a protruding post 1001 slidably fitted with the spiral groove 801 mounted on the slider 10, a lever 13 cooperating with the sliding turntable 4 mounted on the slider 10, and multiple sets of guide rods 11 mounted on the mounting plate 1, with guide sleeves 12 slidably fitted on the guide rods 11 and fixedly connected to the slider 10.
[0080] In Example 7, two sets of levers 13 are respectively arranged on both sides of the sliding turntable 4. The lever 13 closer to the fixed turntable 6 is in contact with the sliding turntable 4, while the other lever 13 is separated from the sliding turntable 4.
[0081] In this embodiment, when the spool 2 rotates in the forward direction, it will drive the first gear 3 to rotate in the forward direction, thereby driving the second gear 9 to rotate in the reverse direction through meshing, which in turn drives the first shaft 8 to rotate in the reverse direction.
[0082] When the first rotating shaft 8 rotates in the reverse direction, it will drive the spiral groove 801 to rotate synchronously. Through sliding cooperation, it will drive the protruding column 1001 to move away from the scroll 2, thereby driving the slider 10 to move; thus driving the lever 13 and the guide sleeve 12 to move synchronously.
[0083] When lever 13 moves away from the spool 2, lever 13, which is separated from the sliding turntable 4, will gradually approach and contact the sliding turntable 4. After contact, it will drive the sliding turntable 4 to move synchronously, thereby driving the sliding turntable 4 to approach the fixed turntable 6. This will cause the first tooth block 401 to mesh with the second tooth block 601, so that the fixed turntable 6 can drive the sliding turntable 4 to rotate in the opposite direction, thereby driving the spool 2 to rotate in the opposite direction and thus retracting the telescopic belt 14.
[0084] During this process, the lever 13 that is in contact with the sliding turntable 4 will disengage from the sliding turntable 4 and move away from the scroll 2.
[0085] When the fixed turntable 6 drives the scroll 2 to rotate in the reverse direction, the first gear 3 will drive the second gear 9 to rotate in the forward direction, thereby driving the first rotating shaft 8 to rotate in the forward direction, which in turn drives the spiral groove 801 to rotate synchronously, thereby driving the slider 10 to slide closer to the scroll 2, which in turn drives the lever 13 and the guide sleeve 12 to move synchronously.
[0086] During this process, one lever 13 will disengage from the sliding turntable 4 and gradually move away from it; the other lever 13 will gradually approach the sliding turntable 4 and, after contact, drive the sliding turntable 4 to move synchronously, so that the sliding turntable 4 gradually moves away from the fixed turntable 6, thereby causing the first tooth block 401 to disengage from the second tooth block 601, stopping the sliding turntable 4 from rotating in the opposite direction, thus stopping the retraction of the telescopic belt 14.
[0087] When the telescopic belt 14 extends to a certain length, the roller 2 rotates several times in the forward direction. At this time, the retrieval structure will drive the roller 2 to rotate in the reverse direction to retrieve the telescopic belt 14, thereby moving the protective pillow 16 closer to the hospital bed to reapply restraining force and prevent the patient from sitting up or having large-scale convulsions.
[0088] Because the length of the elastic band 14 is not locked during the patient's convulsions (it can extend a certain distance), that is, the restraint is an elastic restraint, the patient can shake and convulse slightly, and it does not have the function of forced restraint, which can avoid secondary injury to the patient when the disease occurs.
[0089] Example 8: A guide 7, which is fixedly connected to the hospital bed, is slidably installed on the telescopic belt 14.
[0090] In this embodiment, the guide 7 can prevent the telescopic belt 14 from directly contacting the bed, thereby reducing wear and tear on the bed.
[0091] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
