Description

Technical Field

[0001] This invention relates to the field of medical assistive device technology, specifically to an adjustable-angle restraint and protection device for the care of elderly psychiatric patients. Background Technology

[0002] In geriatric psychiatric clinical nursing, some patients may exhibit dangerous behaviors such as self-harm, harming others, or destroying property due to cognitive impairment, emotional agitation, etc. Therefore, it is necessary to use restraint and protective devices to appropriately restrain the patient's limbs to ensure the safety of the patient and medical staff, so as to facilitate nursing procedures.

[0003] Most existing restraint and protection devices for psychiatric patients are fixed structures, forcing patients to maintain a single supine position without the ability to adjust the patient's position according to their needs. Prolonged use can lead to pressure sores, muscle stiffness, and patient agitation and resistance, increasing the workload of nursing care. At the same time, the force of existing restraint devices is mostly difficult to control precisely, easily resulting in poor blood circulation in the patient's limbs due to excessive tightness or ineffective protection due to excessive looseness. Therefore, there is an urgent need for an adjustable restraint and protection device for elderly psychiatric patients, which can safely restrain and protect while flexibly adjusting the patient's position to meet the needs of patients of different body types and achieve restraint and protection in various postures, thereby improving patient comfort and nursing efficiency. Summary of the Invention

[0018] The following specific embodiments are merely illustrative of the present invention and are not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present invention.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Example

[0021] according to Figures 1-5 As shown, an adjustable restraint and protection device for elderly psychiatric patients includes a mounting base 1, a support base 2, an angle adjustment component 3, a restraint and protection component 4, and a buffer and limiting component 5. The support base 2 includes a first support part 21 and a second support part 22 that are hinged to each other. The angle adjustment component 3 includes a base adjustment component 31 and a restraint adjustment component 32. The second support part 22 is fixedly connected to the mounting base 1. The base adjustment component 31 is detachably connected to the mounting base 1 and movably connected to the first support part 21, and is used to adjust the angle between the first support part 21 and the second support part 22. The restraint and protection component 4 is disposed on the support base 2, and the restraint adjustment component 32 is used to adjust the angle between the restraint and protection component 4 and the support base 2.

[0022] according to Figure 1 , Figure 2 As shown, in this embodiment, the base adjustment assembly 31 includes a base drive 311 and a movable slider 312. The cylinder of the base drive 311 is hinged to the base adjustment mounting part 211 on the back of the first support part 21, and the movable slider 312 is hinged to the push rod output end of the base drive 311. A guide rail 11 is fixedly connected to the mounting base 1, and the movable slider 312 is movably disposed on the guide rail 11. The base drive 311 is used to drive the movable slider 312 to slide on the guide rail 11 to adjust the angle between the first support part 21 and the second support part 22. The first support part 21 and the second support part 22 are hinged together by a connecting part 23, which is fixedly mounted on the mounting base 1. A boss 12 is also fixedly provided on the surface of the mounting base 1 to support the first support part 21 when the angle is in a horizontal position.

[0023] The base drive component 311 is an electric push rod, the cylinder of which is hinged to the base adjustment mounting part 211 on the back of the first support part 21. The output end of the push rod is hinged to the movable slider 312, which is movably connected to the guide rail 11 of the mounting base 1. The base drive component 311 and the guide rail 11 are in the same straight line position. During use, medical staff can send adjustment commands to the main controller of the device through the control button. The controller can control the push rod of the base drive component 311 to extend or retract, thereby driving the movable slider 312 hinged at the end of the push rod to slide along the guide rail 11, realizing the adjustment of the first support on the support base 2. The angle of the support 21 can be adjusted. After the angle is adjusted, the base drive 311 will provide sufficient self-locking force, so that the device can provide sufficient back support after the patient lies down, which improves the comfort of using the device and meets the angle requirements of different operations during the nursing process. The surface of the mounting base 1 is also provided with a boss 12 at the position of the first support 21, which is used to provide support when the first support 21 is flat. At the same time, the height of the boss 12 can also determine the gap between the support base 2 and the mounting base 1. When different sizes of base drive 311 need to be installed, only the boss 12 of the corresponding size needs to be replaced to meet the installation requirements.

[0024] according to Figure 3 , Figure 4As shown, in this embodiment, the restraint and protection component 4 includes a movable base 41, an arc-shaped restraint frame 42, and a flexible restraint belt 43 arranged sequentially from bottom to top. The restraint adjustment component 32 includes a restraint drive member 321, a rack 322, and a rotating gear 323. The restraint drive member 321 is fixedly disposed inside the movable base 41, and the arc-shaped restraint frame 42 is fixedly connected to the rotating gear 323. The rack 322 is fixedly connected to the drive end of the restraint drive member 321, and the rack 322 is provided with meshing... The rack 3221 and the limiting part 3222 are provided. The moving seat 41 is provided with a limiting post 411 and a hinge shaft 412 on one end of the rack 322. The rotating gear 323 is hinged to the hinge shaft 412. One end of the rack 322 is connected to the rotating gear 323 through the meshing teeth 3221, and the other end is attached to the limiting post 411 through the limiting part 3222. The constraint drive member 321 drives the rack 322 to drive the rotating gear 323 to rotate, thereby driving the arc-shaped constraint frame 42 to adjust the angle.

[0025] In use, the patient's arm or leg is placed on the arc-shaped restraint frame 42 of the restraint protection component 4 and restrained and fixed by the flexible restraint strap 43. The restraint adjustment component 32 is used to adjust the angle position of the arc-shaped restraint frame 42. During use, medical staff send restraint adjustment commands to the main controller through the control button. The restraint drive component 321 can drive the rack 322 at the output end to make linear movements. The rotating gear 323 meshes with the rack 322, converting the linear movement of the rack 322 into the rotational movement of the rotating gear 323. Then, through the rigid connection between the rotating gear 323 and the arc-shaped restraint frame 42, the arc-shaped restraint frame 42 can be adjusted in angle. By adjusting the extension and retraction length of the rack 322, the adjustment angle of the arc-shaped restraint frame 42 can be precisely controlled. The limiting part 3222 at the end of the rack 322 and the limiting post 411 on the moving seat 41 can ensure the accuracy of the angle adjustment process. The speed control of the restraint drive component 321 can ensure the stability of the angle adjustment process.

[0026] according to Figure 4 As shown, in this embodiment, the buffer limiting component 5 includes a buffer pad 51, a pressure sensor 52, and an early warning device 53. The buffer pad 51 is fixed to the inner side of the arc-shaped constraint frame 42, the pressure sensor 52 is embedded in the surface of the buffer pad 51, and the early warning device 53 is fixed to the outside of the arc-shaped constraint frame 42. The pressure sensor 52 and the early warning device 53 are electrically connected.

[0027] The cushioning pad 51 is located on the inner surface of the arc-shaped restraint frame 42, which can improve the wearing comfort of the restraint protection component 4 and prevent the patient's skin from being directly rubbed against the hard arc-shaped restraint frame 42, causing damage. The pressure sensor 52 can monitor the pressure on the patient's limbs in real time during the restraint process. When the pressure exceeds the set threshold, the warning device 53 will issue an audible and visual warning to remind medical staff to adjust the restraint force in time to avoid poor blood circulation in the patient's limbs due to excessive restraint. During use, the patient's limbs are placed on the cushioning pad 51 of the arc-shaped restraint frame 42, and medical staff use the flexible restraint strap 43 to restrain and fix the limbs. The pressure sensor 52 monitors the pressure on the patient's limbs in real time and transmits the pressure signal to the controller. When the pressure threshold is exceeded, the controller sends a signal to control the warning device 53 to issue an audible and visual warning, and medical staff can adjust the tightness of the flexible restraint strap 43 in time to reduce the restraint force.

[0028] according to Figure 5 As shown, in this embodiment, a lateral adjustment assembly 6 is also provided on the support base 2. The lateral adjustment assembly 6 includes an adjustment seat 61, a drive motor 62, a drive gear 63, a driven gear 64, and a rotating shaft 65. The adjustment seat 61 is fixed on the support base 2. The lateral adjustment assembly 6 is threadedly connected to the movable seat 41 through the rotating shaft 65. The support base 2 is also provided with a guide groove 24 for constraining the movement of the restraint and protection assembly 4. The drive motor 62 is fixed inside the adjustment seat 61. The drive gear 63 is located at the output end of the drive motor 62. One end of the rotating shaft 65 is fixedly provided with a driven gear 64 that meshes with the drive gear 63, and the other end is threadedly connected to the movable seat 41. Two sets of restraint and protection assemblies 4 are provided. The two sets of restraint and protection assemblies 4 are symmetrically distributed on both sides of the adjustment seat 61, and both are meshed with the drive gear 63 through the rotating shaft 65.

[0029] The lateral adjustment component 6 can adjust the distance between the two symmetrically arranged restraint and protection components 4, allowing the restraint device to meet the needs of patients of different body types. Lateral adjustment of the restraint and protection components 4 also provides further restraint for the patient, limiting their movement by adjusting the distance between their hands or legs. During use, medical staff send a lateral adjustment command to the main controller via a control button. The controller then starts the drive motor 62, which drives the output drive gear 63 to rotate. The drive gear 63 in turn drives the driven gear 64 to rotate, which in turn drives the rotating shaft 65 to rotate. The rotating shaft 65 causes the threaded movable seat 41 connected to it to move laterally, thus achieving lateral adjustment of the restraint and protection components 4. The threads of the rotating shafts 65 on the two symmetrically arranged restraint and protection components 4 are opposite. When the drive motor 62 rotates, the two symmetrical restraint and protection components 4 can simultaneously expand outward or contract inward, achieving synchronous lateral adjustment of the same set of restraint and protection components 4.

[0030] In this embodiment, the support base 2 is further provided with a flexible layer 7, which includes a body restraint unit 71 and a waist restraint unit 72. The body restraint unit 71 includes at least one restraint strap that crosses the patient's chest, and the waist restraint unit 72 includes at least one restraint strap that crosses the patient's waist. Both the body restraint unit 71 and the waist restraint unit 72 are detachably connected to the flexible layer 7. The body restraint unit 71 and the waist restraint unit 72 are integrated into the flexible layer 7 and are both made of breathable soft materials, which improves the comfort of using the restraint device. The body restraint unit 71 and the waist restraint unit 72 can restrict the patient's large-scale movements and provide a certain amount of elastic movement space, so that it can always maintain an effective protective state without causing additional pressure or friction to the patient.
