Technical Field
[0001] The present invention belongs to the technical field of medical care, and particularly relates to a nursing protection device for the psychiatric department. Background Art
[0002] The diseases involved in the psychiatric department are mainly mental illnesses, which are a group of nervous system diseases mainly manifested by disorders in behavior and psychological activities. In the care of psychiatric patients, a special nursing cart is required.
[0003] In the prior art, a general nursing cart has no protection function, which is likely to cause patients to move around during the nursing process, increasing the work difficulty of medical staff. Moreover, the emotional state of psychiatric patients is extremely unstable, and they may harm medical staff during the nursing process. Therefore, we provide a nursing protection device for the psychiatric department to solve the above problems. Summary of the Invention
[0004] The purpose of the present invention is to provide a nursing protection device for the psychiatric department. Through the specific structural design of the wheelchair armrest plate, wheelchair bottom bracket, foot pedal drive assembly, first transmission assembly, restraint mechanism, support beam and protective cover, the problem that the existing nursing cart has no protection function and is likely to cause harm to medical staff due to the unstable emotions of patients during the nursing process is solved.
[0005] To solve the above technical problems, the present invention is realized through the following technical solutions: The present invention is a nursing protection device for the psychiatric department, including a wheelchair armrest plate, a wheelchair bottom bracket, a foot pedal drive assembly, a first transmission assembly and a restraint mechanism. The foot pedal drive assembly is rotatably installed on the wheelchair bottom bracket, and the foot pedal drive assembly includes an arc-shaped tooth part. The first transmission assembly is installed on the top of the wheelchair armrest plate. The first transmission assembly includes a first transmission part and a second transmission part, and the first transmission part and the second transmission part are connected by a third transmission part. The arc-shaped tooth part meshes with the first transmission part. The restraint mechanism includes an arm placement assembly, a restraint ring group and a second transmission assembly. The arm placement assembly is installed on the top of the wheelchair armrest plate. The second transmission assembly is rotatably installed on the arm placement assembly. The restraint ring group is slidably connected to the second transmission assembly.
[0006] The present invention is further provided that the foot pedal drive assembly further includes a foot pedal rod rotatably provided on the wheelchair bottom bracket. A support beam installed at the bottom of the wheelchair is fixed to the top of the wheelchair bottom bracket. One end of the foot pedal rod is fixed with a foot pedal, and the other end of the foot pedal rod is fixed with a support frame. The arc-shaped tooth parts are symmetrically fixed on the support frame.
[0007] The present invention is further configured such that the first transmission assembly further includes a first support plate, a support rod, and a second support plate fixed to the top of the wheelchair armrest. The third transmission portion is slidably sleeved on the support rod. The first transmission portion includes a first rotating shaft rotatably disposed on the third transmission portion. A first connecting plate is fixed to the end of the first rotating shaft. A first transmission member is fixed at an eccentric position of the first connecting plate. The first transmission member is rotatably disposed on the first support plate and meshes with the arc-shaped tooth member.
[0008] The present invention is further configured such that the second transmission portion includes a second rotating shaft rotatably disposed on the third transmission portion. A second connecting plate is fixed to the end of the second rotating shaft. A second transmission member is fixed at an eccentric position of the second connecting plate. The second transmission member is rotatably disposed on the second support plate.
[0009] The present invention is further configured such that the arm placement assembly includes a first mounting bracket and a second mounting bracket fixed to the top of the wheelchair armrest. A restraint member is fixed between the first mounting bracket and the second mounting bracket. The restraint member is in a semi-cylindrical structure. An inclined surface limiting plate is fixed to the outer side of the restraint member.
[0010] The present invention is further configured such that the second transmission assembly includes a first linkage plate and a second linkage plate. The first linkage plate is rotatably sleeved on the first mounting bracket. The second linkage plate is rotatably sleeved on the second mounting bracket. A third transmission member sleeved on the first mounting bracket is fixed to the first linkage plate. The third transmission member meshes with the second transmission member. A load-bearing rod is fixed between the first linkage plate and the second linkage plate. A limiting groove is formed on the circumferential side of the load-bearing rod.
[0011] The present invention is further configured such that the restraint ring group includes an arc-shaped restraint plate sleeved on the restraint member. A sliding member slidably connected to the limiting groove is fixed to the circumferential side of the arc-shaped restraint plate. A guiding member is fixed to the inner wall of the arc-shaped restraint plate. The outer diameter of the guiding member is the same as the inner diameter of the restraint member. An inclined surface locking member is slidably disposed in the mounting cavity at the end of the arc-shaped restraint plate. The inclined surface locking member is connected to a spring in the mounting cavity. A pushing and pulling member connected to the inclined surface locking member is sleeved on the arc-shaped restraint plate.
[0012] The present invention has the following beneficial effects: 1. During the process of stepping on the footrest of the present invention, the counterclockwise rotating arc-shaped tooth member drives the first transmission member to rotate clockwise. The clockwise rotating first transmission portion drives the third transmission portion to slide along the support rod. Furthermore, the third transmission portion drives the second transmission portion to rotate. Then, the second transmission portion drives the second transmission assembly and each restraint ring group thereon to rotate synchronously. In this way, the forearms of mental patients can be restrained and fixed by each restraint ring group.
[0013] 2. During the process of controlling the rotation of the second transmission component in the present invention, each set of restraint rings that rotates synchronously with the second transmission component gradually approaches the inclined surface limiting plate. When the inclined surface locking member contacts the inclined surface of the inclined surface limiting plate, the inclined surface locking member is squeezed by the inclined surface limiting plate to move and compress the spring until the inclined surface locking member disengages from the inclined surface limiting plate. At this time, under the action of the elastic restoring force of the spring, the inclined surface locking member is driven to complete the reset and press against the outer wall of the restraint member. At this time, the inclined surface locking member is blocked by the inclined surface limiting plate and cannot be reset, thereby realizing the position fixation of each arc-shaped restraint plate, and completing the restraint and fixation of the patient's forearm at this time.

Detailed implementation manners
[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.
[0030] For the first specific embodiment, please refer to Figure 1-12 , the present invention is a psychiatric nursing protection device, including a wheelchair armrest 1, a wheelchair bottom bracket 2, a pedal drive assembly 3, a first transmission assembly 4 and a restraint mechanism 5; the pedal drive assembly 3 is rotatably installed on the wheelchair bottom bracket 2, and the pedal drive assembly 3 includes an arc-shaped tooth part 301; the first transmission assembly 4 is installed on the top of the wheelchair armrest 1, the first transmission assembly 4 includes a first transmission part and a second transmission part, the first transmission part and the second transmission part are connected by a third transmission part 410, and the arc-shaped tooth part 301 meshes with the first transmission part; the restraint mechanism 5 includes an arm placement assembly 6, a restraint ring group 7 and a second transmission assembly 8, the arm placement assembly 6 is installed on the top of the wheelchair armrest 1, the second transmission assembly 8 is rotatably installed on the arm placement assembly 6, and the restraint ring group 7 is slidably connected to the second transmission assembly 8.
[0031] In some embodiments, as Figure 3 shown, the foot pedal drive assembly 3 further includes a foot pedal rod 302 rotatably disposed on the bottom bracket 2 of the wheelchair. A support beam 9 installed at the bottom of the wheelchair is fixed to the top of the bottom bracket 2 of the wheelchair. One end of the foot pedal rod 302 is fixed with a foot pedal 303, and the other end of the foot pedal rod 302 is fixed with a support frame 304. The arc-shaped tooth parts 301 are symmetrically fixed on the support frame 304. During the nursing process, medical staff can drive the support frame 304 at the end of the foot pedal rod 302 to rotate upward by stepping on the foot pedal 303, thereby realizing the synchronous counterclockwise rotation of the arc-shaped tooth parts 301 on both sides.
[0032] In some embodiments, as Figure 2 、 Figure 6 and Figure 11 shown, the first transmission assembly 4 further includes a first support plate 401, a support rod 402 and a second support plate 403 fixed to the top of the wheelchair armrest 1. The third transmission part 410 is slidably sleeved on the support rod 402; the first transmission part includes a first rotating shaft 404 rotatably disposed on the third transmission part 410. A first connecting plate 405 is fixed to the end of the first rotating shaft 404, and a first transmission member 406 is fixed at an eccentric position of the first connecting plate 405. The first transmission member 406 is rotatably disposed on the first support plate 401 and meshes with the arc-shaped tooth part 301. Thus, during the process of stepping on the foot pedal 303, the arc-shaped tooth part 301 rotating counterclockwise can drive the first transmission member 406 to rotate clockwise, thereby realizing the clockwise rotation control of the first transmission part.
[0033] In some embodiments, as Figure 2 、 Figure 6 and Figure 12 shown, the second transmission part includes a second rotating shaft 407 rotatably disposed on the third transmission part 410. A second connecting plate 408 is fixed to the end of the second rotating shaft 407, and a second transmission member 409 is fixed at an eccentric position of the second connecting plate 408. The second transmission member 409 is rotatably disposed on the second support plate 403 (the protective cover 10 is installed on the front side of the nursing vehicle for protecting the Figure 2 gear structure shown). During the process of stepping on the foot pedal 303, the arc-shaped tooth part 301 rotating counterclockwise drives the first transmission member 406 to rotate clockwise. The clockwise rotating first transmission part drives the third transmission part 410 to slide along the support rod 402, and then drives the second transmission part to rotate through the third transmission part 410. The second transmission part drives the second transmission assembly 8 and each restraint ring group 7 thereon to rotate synchronously. Thus, the forearms of the mental patients can be restrained and fixed through each restraint ring group 7.
[0034] Specific Embodiment 2, based on Specific Embodiment 1, as Figure 7 shown, the arm placement assembly 6 includes a first mounting bracket 601 and a second mounting bracket 602 fixed to the top of the wheelchair armrest 1. A restraint 603 is fixed between the first mounting bracket 601 and the second mounting bracket 602. The restraint 603 is of a semi-cylindrical structure, and an inclined surface limiting plate 604 is fixed to the outside of the restraint 603. The second transmission assembly 8 includes a first linkage plate 801 and a second linkage plate 802. The first linkage plate 801 is rotatably sleeved on the first mounting bracket 601, and the second linkage plate 802 is rotatably sleeved on the second mounting bracket 602. A third transmission member 803 sleeved on the first mounting bracket 601 is fixed to the first linkage plate 801. The third transmission member 803 meshes with the second transmission member 409. A load-bearing rod 804 is fixed between the first linkage plate 801 and the second linkage plate 802. A limiting groove 805 is formed on the circumferential side surface of the load-bearing rod 804.
[0035] During the process of stepping on the foot pedal 303, the arc-shaped tooth member 301 rotating counterclockwise drives the first transmission member 406 to rotate clockwise. The clockwise rotating first transmission part drives the third transmission part 410 to slide along the support rod 402. Then, the third transmission part 410 drives the second transmission part to rotate. The second transmission member 409 on the second transmission part drives the third transmission member 803 to rotate, thereby realizing the rotation of the entire second transmission assembly 8. Each restraint ring group 7 on the second transmission assembly 8 rotates synchronously and gradually surrounds the forearms of the mental patients (when nursing, the mental patients are made to sit on the nursing chair cart, and the forearms of the patients are placed inside the restraints 603 on both sides). In this way, the forearms of the mental patients can be restrained and fixed by each restraint ring group 7.
[0036] In some embodiments, as Figure 9 and Figure 10As shown, the restraint ring set 7 includes an arc-shaped restraint plate 701 sleeved on the restraint member 603. A sliding member 702 slidably connected to the limit groove 805 is fixed on the circumferential side of the arc-shaped restraint plate 701. In this way, the distance between each restraint ring set 7 can be adjusted according to the length of the patient's forearm, so as to achieve the maximum restraint and fixation of the patient's forearm. A guiding member 703 is fixed on the inner wall of the arc-shaped restraint plate 701, and the outer diameter of the guiding member 703 is the same as the inner diameter of the restraint member 603. A bevel locking member 704 is slidably arranged in the installation cavity at the end of the arc-shaped restraint plate 701. The bevel locking member 704 is connected to a spring 705 in the installation cavity. A pushing and pulling member 706 connected to the bevel locking member 704 is sleeved on the arc-shaped restraint plate 701. During the rotation of the second transmission assembly 8, each restraint ring set 7 rotating synchronously with the second transmission assembly 8 gradually approaches the bevel limit plate 604. When the bevel locking member 704 contacts the bevel surface of the bevel limit plate 604, the bevel locking member 704 is squeezed by the bevel limit plate 604 and moves to compress the spring 705 until the bevel locking member 704 disengages from the bevel limit plate 604. At this time, under the elastic restoring force of the spring 705, the bevel locking member 704 is driven to complete the reset and press against the outer wall of the restraint member 603. At this time, the bevel locking member 704 is blocked by the bevel limit plate 604 and cannot be reset. Thus, the positions of the arc-shaped restraint plates 701 are fixed, and the restraint and fixation of the patient's forearm are completed. After the nursing is completed, by pulling the pushing and pulling member 706 outward, the bevel locking member 704 moves to compress the spring 705. At this time, the bevel limit plate 604 releases the limiting effect on the bevel locking member 704. Then, during the downward movement of the overall gravity of the foot pedal drive assembly 3, the second transmission assembly 8 and each restraint ring set 7 thereon are controlled to rotate synchronously in the reverse direction by the arc-shaped tooth member 301 rotating clockwise to complete the reset, and each restraint ring set 7 synchronously releases the restraint and fixation of the forearm of the mental patient.
