Description

Technical Field

[0001] This utility model relates to the field of medical and nursing technology, specifically a restraint chair for the care of patients with mental illness. Background Technology

[0002] Mental illness refers to diseases caused by the dysfunction of the brain under the influence of various biological, psychological and social environmental factors, resulting in varying degrees of impairment in mental activities such as cognition, emotion, will and behavior. When caring for mental patients, a restraint chair for mental illness patients needs to be used.

[0003] Existing restraint chairs cannot effectively adjust the angle and position of the backrest and leg rest, which can lead to discomfort for patients after prolonged use, making them more prone to agitation and reducing the overall practicality and flexibility of the device. Furthermore, existing restraint chairs cannot adaptively adjust the tightness of the restraints on the patient's hands according to the actual situation. When the patient's hands are in a tight restraint for a long time, blood circulation may be impaired, which also reduces the overall practicality of the device.

[0004] Compared to patent application CN215739779U, this utility model discloses an upper limb restraint device for patients with mental illness, including a chair with a rotating rod above it. This utility model involves having the mental patient sit in the chair, then the doctor places the patient's hand on the insertion frame and inserts a ring downwards. The ring causes a locking block and a locking claw to slide relative to each other. Once the desired position is reached, the insertion is stopped, and a straight spring presses the locking claw against the locking block, thus fixing the patient's hand. This utility model is simple and convenient to design, providing good restraint while avoiding the inconvenience caused by prior art restraints, such as difficulties with eating.

[0005] The above-mentioned methods can effectively restrain the patient's hands and facilitate tasks such as eating. However, these methods still cannot effectively adjust the angles of the backrest and leg rests, and they also cannot adaptively adjust the tightness of the hand restraints based on the patient's struggles. Therefore, a restraint chair for the care of patients with mental illness is now proposed. Utility Model Content

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0036] In one embodiment, such as Figures 1-8 As shown, a restraint chair for the care of patients with mental illness includes a seat 1. A connecting frame 2 is fixedly connected to the left and right surfaces of the seat 1. The front and rear surfaces of the connecting frame 2 are provided with mounting holes for mounting rotating rods 3. Turntables 4 are fixedly connected to both ends of the two rotating rods 3. A leg rest plate 5 is fixedly connected to the outside of one rotating rod 3, and a backrest 6 is fixedly connected to the outside of the other rotating rod 3.

[0037] Angle adjustment components are respectively set on the front and rear surfaces of the two connecting frames 2, and are used to adjust the angles of the leg rest 5 and the backrest 6.

[0038] The leg restraint assembly is symmetrically arranged on the left side surface of the leg placement plate 5 and is used to restrain the patient's legs.

[0039] Support plates 7 are fixedly connected to the front and rear surfaces of the seat plate 1, respectively. Handrails 8 are fixedly connected to the upper surfaces of the two support plates 7, and lower plates 12 are fixedly connected to the left side of the upper surfaces of the two handrails 8. An upper plate 17 is provided directly above the two lower plates 12.

[0040] The adaptive adjustment components are fixedly connected to the outside of the two handrails 8 respectively, and are used to adjust the distance between the upper plate 17 and the lower plate 12.

[0041] In this embodiment, when it is necessary to restrain the patient, the patient is first seated on the seat 1, and then the leg restraint assembly is used to restrain and fix the patient's legs. After the patient's legs are restrained, the upper plate 17 and the lower plate 12 are used to restrain the patient's hands. When the patient struggles violently, the adaptive adjustment assembly can effectively shorten the distance between the upper plate 17 and the lower plate 12, thereby further improving the restraint effect on the patient's hands and reducing the degree of struggle. When the patient stops struggling, the adaptive adjustment assembly will increase the distance between the upper plate 17 and the lower plate 12, thereby allowing the patient's hands to relax and preventing poor blood circulation in the patient's hands, effectively improving the patient's comfort and the overall practicality of the device. When it is necessary to adjust the angle of the backrest 6 and the leg rest 5, the angle adjustment assembly can be used to conveniently and effectively adjust the angle of the backrest 6 or the leg rest 5, thereby effectively improving the patient's comfort during the use of the device and further improving the overall practicality and flexibility of the device.

[0042] In one embodiment, such as Figure 2 and Figure 7 As shown, the angle adjustment assembly includes an L-shaped plate 28 fixedly connected to the front and rear surfaces of the connecting frame 2, respectively. A locking block 29 is fixedly connected to the outside of the L-shaped plate 28. A locking rod 30 is provided inside the locking block 29. A pull plate is fixedly connected to one end of the locking rod 30. An abutment plate 31 is fixedly connected to the outside of the locking rod 30. A return spring 32 is sleeved on the outside of the locking rod 30. The return spring 32 abuts between the abutment plate 31 and the locking block 29. Guide grooves for the locking rod 30 to move are opened on the contact surfaces of the locking block 29 and the L-shaped plate 28. Slots for the locking rod 30 to move are opened at equal intervals inside the turntable 4. When it is necessary to adjust the angle of the backrest 6 or the leg rest 5, simply pull the pull plate first. At this time, the pull plate will drive the locking rod 30 to move synchronously. The locking lever 30 then moves the contact plate 31 synchronously. During the movement of the contact plate 31, it compresses the return spring 32. When the locking lever 30 disengages from the slot inside the turntable 4, the backrest 6 or leg rest plate 5 is then moved. At this time, the backrest 6 or leg rest plate 5 will drive the rotating lever 3 to rotate synchronously. The rotating lever 3 will then drive the turntable 4 to rotate synchronously. When the backrest 6 or leg rest plate 5 is adjusted to a suitable angle, the pull plate is released. At this time, the return spring 32 returns to its original position, driving the contact plate 31 and the locking lever 30 to move synchronously. When the locking lever 30 is inserted into the slot inside the turntable 4, the turntable 4 can be locked. At this time, the angle of the backrest 6 or leg rest plate 5 can be locked, thereby effectively improving the patient's comfort.

[0043] In one embodiment, such as Figure 5 and Figure 8As shown, the leg restraint assembly includes arc plates 24 symmetrically arranged on the left side surface of the leg placement plate 5. Connecting blocks 23 are symmetrically arranged on one side of the arc plates 24. Restraint straps 25 are fixedly connected to the outside of the connecting blocks 23. Insert plates 33 are fixedly connected to the other end of the restraint straps 25. Fixing frames 34 are symmetrically arranged on opposite sides of the two arc plates 24. Guide grooves for the insertion plates 33 to move are opened inside the fixing frames 34. An inner plate 35 is fixedly connected to the middle of the inner wall of the insertion plate 33. Slide rods 36 are symmetrically arranged on the upper and lower surfaces of the inner plate 35. The other ends of multiple slide rods 36 are fixedly connected to the inner wall of the insertion plate 33. A sliding plate 37 is slidably connected to the outside of every two slide rods 36. A retaining spring 38 is sleeved on the outside of each slide rod 36. Multiple retaining springs 38 abut against the sliding plate 37 and the inner plate 35. Arc-shaped locking blocks 39 are fixedly connected to the outside of the sliding plate 37. Arc-shaped locking blocks are opened on the upper and lower surfaces of the insertion plate 33 and the fixing frames 34. The movable slot 39 allows for leg restraint when the patient's legs need to be secured. First, the patient's legs are placed inside the arc plate 24, then the insert plate 33 is inserted into the fixed frame 34. The insert plate 33 then moves the arc-shaped locking block 39 synchronously. When the arc-shaped locking block 39 moves into the fixed frame 34, it is compressed, causing the sliding plate 37 to move synchronously outside the sliding rod 36. During the movement of the sliding plate 37, it compresses the resisting spring 38. When the insert plate 33 moves the arc-shaped locking block 39 into the movable slots on the upper and lower surfaces of the fixed frame 34, the resisting spring 38 resets, causing the sliding plate 37 and the arc-shaped locking block 39 to move synchronously. When the arc-shaped locking block 39 is inserted into the movable slots on the upper and lower surfaces of the fixed frame 34, the insert plate 33 is fixed to the fixed frame 34. At this point, the patient's legs can be effectively restrained and secured using the restraint strap 25.

[0044] In one embodiment, such as Figure 5 and Figure 8As shown, multiple fixed frames 34 are all fixedly connected to an outer plate 40. Telescopic rods 41 are fixedly connected to the upper and lower surfaces of the outer plates 40. A pressing plate 42 is fixedly connected to the telescopic end of the telescopic rod 41. A compression spring 43 is sleeved on the outside of the telescopic rod 41, and the compression spring 43 abuts against the pressing plate 42 and the outer plate 40. A squeezing block 44 is fixedly connected to the opposite side of every two pressing plates 42. When it is necessary to cancel the fixation effect on the patient's leg, simply press the pressing plate 42 first. At this time, the pressing plate 42 will compress the telescopic rod 41. The compression spring 43 compresses synchronously, and the pressing plate 42 also drives the pressing block 44 to move synchronously. When the pressing block 44 presses the arc-shaped locking block 39 into the movable groove that is separated from the upper and lower surfaces of the fixed frame 34, the restraint strap 25 is pulled. At this time, the restraint strap 25 will drive the insert plate 33 to move synchronously. When the insert plate 33 is separated from the inside of the fixed frame 34, the fixation effect on the patient's leg can be canceled. At this time, the medical staff releases the pressing plate 42, and the compression spring 43 will reset synchronously, driving the pressing plate 42 to reset synchronously.

[0045] In one embodiment, such as 1- Figure 5 As shown, each of the multiple telescopic rods 41 is fitted with a bellows cover 45. The two ends of the bellows cover 45 are fixedly connected to the opposite side of the pressing plate 42 and the outer plate 40, respectively. By setting the bellows cover 45, the telescopic rods 41 and the compression springs 43 can be effectively protected, thereby effectively extending the service life of the telescopic rods 41 and the compression springs 43, without affecting the normal use of the telescopic rods 41 and the compression springs 43.

[0046] In one embodiment, such as Figure 3 and Figure 6As shown, the adaptive adjustment assembly includes an adjustment plate 13 fixedly connected to the outside of the armrest 8. A threaded rod 14 is rotatably connected to the top of the inner part of the adjustment plate 13. A fixed plate 18 is fixedly connected to the bottom of the seat plate 1. The bottom ends of both threaded rods 14 are rotatably connected to the upper surface of the fixed plate 18. A drive motor 21 is fixedly connected to the rear of the lower surface of the fixed plate 18. The output shaft of the drive motor 21 is fixedly connected to the bottom end of one of the threaded rods 14 via a coupling. The two threaded rods 14 are connected by a synchronous belt 19 and a pulley 20 for transmission. Both threaded rods 14 are threadedly connected to threaded blocks 15 on their outer sides. Guide grooves for the movement of the threaded blocks 15 are provided on opposite sides of both adjusting plates 13. The opposite sides of both threaded blocks 15 are fixedly connected to the middle of the upper surfaces of both upper plates 17 via side plates 16. Airbags 27 are bonded to the bottom of both upper plates 17. Pressure sensors 26 are located between the airbags 27 and the upper plates 17. When the patient struggles violently, their hands will continuously squeeze the airbags 27, which in turn will simultaneously squeeze the pressure sensors 26. When the pressure sensor 26 is subjected to continuous pressure of varying degrees, it transmits a signal to the controller. The controller then controls the drive motor 21 to start running. At this time, the drive motor 21 drives one of the threaded rods 14 to rotate synchronously. Since the two threaded rods 14 are connected by a synchronous belt 19 and a pulley 20, they rotate synchronously. The threaded block 15 moves synchronously outside the threaded rods 14, causing the side plate 16 and the upper plate 17 to move synchronously. This shortens the distance between the upper plate 17 and the lower plate 12, thereby further improving the overall restraint effect of the device on the patient's hand. When the patient is stable, the pressure sensor 26 detects that the pressure fluctuations are not large and are relatively stable. At this time, the pressure sensor 26 transmits a signal to the controller again. The controller then controls the drive motor 21 to reverse, thereby increasing the distance between the upper plate 17 and the lower plate 12. This allows the patient's hand to relax, preventing poor blood circulation and effectively improving the overall practicality of the device.

[0047] In one embodiment, such as Figures 1-5 As shown, a base plate 9 is symmetrically arranged below the base plate 1. Mounting sleeves 10 are symmetrically arranged on the upper surfaces of both base plates 9. Movable rods 11 are located inside the mounting sleeves 10. The tops of multiple movable rods 11 are fixedly connected to the bottom of the base plate 1. Multiple movable rods 11 are fixedly connected to the mounting sleeves 10 by bolts. When the overall height of the device needs to be adjusted, simply unscrew the bolts and pull the movable rods 11 inside the mounting sleeves 10. When the movable rods 11 move the base plate 1 to a suitable height, the movable rods 11 are then fixed to the mounting sleeves 10 by bolts. At this point, the overall height of the device can be adjusted.

[0048] In one embodiment, such as Figure 4 As shown, rubber anti-slip pads 22 are glued to the bottom of both base plates 9. The rubber anti-slip pads 22 can effectively improve the stability of the device during use and prevent the device from shifting.

[0049] The above embodiment discloses a restraint chair for the care of patients with mental illness. When restraint is required, the patient is first seated on the seat 1, and then the legs are restrained and fixed using restraint straps 25. After the legs are restrained, the patient's hands are restrained using the interaction between the upper board 17 and the lower board 12. When the patient struggles violently, the pressure sensor 26 transmits a signal to the controller, which then controls the drive motor 21 to start running. This shortens the distance between the upper board 17 and the lower board 12, further enhancing the restraint effect on the patient's hands and reducing the degree of struggle. When the patient stops struggling... During the procedure, the pressure sensor 26 transmits a relatively stable signal from the patient to the controller, which then controls the drive motor 21 to reverse. This increases the distance between the upper plate 17 and the lower plate 12, allowing the patient's hand to relax and preventing poor blood circulation. This effectively improves patient comfort and the overall practicality of the device. When the angles of the backrest 6 and the leg rest 5 need to be adjusted, simply pull the lever to easily and effectively adjust the angles of the backrest 6 or the leg rest 5. This further enhances patient comfort during use and improves the overall practicality and flexibility of the device.

[0050] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
