Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a multifunctional psychiatric patient restraint chair. Background Art

[0002] In the field of psychiatric medicine, patients often exhibit dangerous behaviors such as impulsiveness, aggression, and self-harm due to the onset of mental symptoms. Traditional restraint methods mostly use manual binding or simple fixing devices, which have many problems. On the one hand, the manual restraint process requires a lot of time and energy from medical staff, and the operation may not be completed quickly and effectively in an emergency, resulting in an increased risk of injury to patients or medical staff. On the other hand, existing restraint tools often lack consideration for the psychological and physical comfort of patients, which can easily cause strong resistance from patients, further aggravate their mental instability, and may even cause unnecessary physical harm to patients, such as skin abrasions and poor blood circulation. At the same time, with the development of psychiatric medical technology and the enhancement of awareness of patient rights protection, the demand for safer, more effective, and more humane restraint methods is becoming increasingly urgent.

[0003] The patent with the publication number CN221556391U discloses a wheelchair for mentally ill patients, including: a wheelchair body, the wheelchair body is provided with a backrest, a protective frame, the upper end of the protective frame is hinged to the upper end of the backrest, and the protective frame can be rotated to the front side of the backrest to block the front side of the patient's body; a locking mechanism, the locking mechanism is arranged on the backrest, and the locking mechanism is used to fix the protective frame; when the patient sits in the wheelchair, he can put his legs into two leg slots respectively, and then close the rotating plate to restrict his legs in the leg slots, and then put the forearms of both hands on the hand slots on both sides respectively, and fix the patient's hands with a fixing belt. Finally, the nursing staff rotates the protective frame to make the protective frame descend, the leg pressing block is pressed on the thigh position, and the bolt knob is tightened to fix the gear, thereby fixing the protective frame, and the mentally ill patient can be safely and humanely restrained in the wheelchair.

[0004] The above technical solution hinges the rotating plate with the wheelchair body. When in use, the rotating plate needs to be manually rotated to restrict the patient's legs in the leg grooves. If the patient has mental symptoms and refuses to cooperate, multiple medical staff are needed to fix the patient's upper limbs so that other medical staff can manually rotate the rotating plate to fix the patient's lower limbs, which consumes a lot of time and energy of the medical staff. In an emergency, the operation may not be completed quickly and effectively, resulting in an increased risk of injury to the patient or medical staff. In addition, the above technical solution lacks consideration for the patient's psychological and physiological comfort, which can easily cause strong resistance from the patient, further aggravating his mental instability, and may even cause unnecessary physical harm to the patient, such as skin abrasions and poor blood circulation.

[0005] Therefore, there is an urgent need to design a psychiatric patient restraint chair that is simple to operate, can quickly and effectively fix the patient, can reduce the patient's resistance and psychological pressure, and is conducive to the stability and recovery of the patient's mental state.

[0024] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] In the description of the present invention, it should be understood that the terms "length direction", "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, features limited to "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The inventors have found that when using the current mental illness restraint device, the rotating plate needs to be manually rotated to confine the patient's legs in the leg groove. If the patient suffers from mental symptoms and refuses to cooperate, multiple medical staff are needed to fix the patient's upper limbs so that other medical staff can manually rotate the rotating plate to fix the patient's lower limbs. This consumes a lot of time and energy of the medical staff, and may not be able to complete the operation quickly and effectively in an emergency, resulting in an increased risk of injury to the patient or medical staff. In addition, the above technical solution lacks consideration for the patient's psychological and physiological comfort, which can easily cause strong resistance from the patient, further aggravating his mental instability, and may even cause unnecessary physical harm to the patient, such as skin abrasions and poor blood circulation.

[0028] Based on the above findings, the present application provides a multifunctional psychiatric patient restraint chair, including a restraint chair body 8, a mounting frame 1 is provided on the seat of the restraint chair body 8, and two limb restraint rods arranged up and down are provided in front of the mounting frame 1, and a massage mechanism 5 is connected to the bottom of the mounting frame 1; wherein, a first accommodating cavity 85 is provided inside the two armrests of the restraint chair body 8, and each first accommodating cavity 85 is provided with a rack 41 and a first transmission assembly 42; the rack 41 is connected to the mounting frame 1 and meshed with the first transmission assembly 42; when in use, after the patient sits on the mounting frame 1, the rack 41 moves downward under the action of the mounting frame 1, and the massage mechanism 5 is squeezed by the mounting frame 1, and the rack 41 drives the limb restraint rod to rotate through the first transmission assembly 42 to fix the patient's lower limbs. At the same time, the massage column 52 in the massage mechanism 5 is inflated to massage the patient's legs, which can reduce the patient's resistance and psychological pressure.

[0029] Example 1 This embodiment provides a multifunctional psychiatric patient restraint chair, such as Figure 1-17 As shown, it includes a restraint chair body 8, and a mounting frame 1, a first limb restraint rod 2, a second limb restraint rod 3, two first transmission mechanisms 4, a massage mechanism 5 and a shoulder fixing ring 6 arranged on the restraint chair body 8.

[0030] like Figure 1 , 9As shown in FIG. 10 , the restraint chair body 8 includes a chair back 81 , two armrests 83 , a chair seat 82 and a leg limiting plate having a leg groove 84 .

[0031] The seat 82 is an elastic structure. Specifically, the seat 82 includes a bottom plate and a sponge pad disposed on the bottom plate, and a spring is disposed inside the sponge pad. The bottom plate of the seat 82 is located at the upper end of the leg limit plate and is fixedly connected to the leg limit plate. In actual use, vertical through holes are respectively provided on both sides of the bottom plate of the seat 82 to facilitate the up and down movement of the first transmission mechanism 4. like Fig.16 and 17 As shown, the mounting frame 1 is sleeved on the seat 82, and connecting plates for connecting with the first transmission mechanism 4 are provided on both sides of the mounting frame 1. In this way, the first transmission mechanism 4 passes through the vertical bar through holes of the bottom plate of the seat 82 and is fixedly connected with the connecting plates on both sides of the mounting frame 1. When in use, the patient sits on the mounting frame 1, as shown in FIG. Fig.17 As shown, the installation frame 1 moves downward due to the patient's own gravity, so that the two first transmission mechanisms 4 connected to the installation frame 1 are activated. At the same time, the massage mechanism 5 is squeezed by the installation frame 1 and intermittently inflated and deflated.

[0032] The first limb restraining rod 2 and the second limb restraining rod 3 are arranged horizontally, and the first limb restraining rod 2 is located at the front side of the seat 82 , and the second limb restraining rod 3 is located at the front side of the leg groove 84 .

[0033] like Figure 1 ,as well as Figure 12-15 As shown, the first limb restraint rod 2 includes a left connecting portion 21, a right connecting portion 22 and a locking mechanism; wherein the locking mechanism includes a limiting ball 23, a spherical groove 24, a limiting spring 25 and a push rod 26; One end of the left connecting part 21 is connected to the first transmission mechanism 4 in the armrest 83 located on one side of the seat 82, and the other end of the left connecting part 21 is provided with a movable groove, and a limit spring 25 and a limit ball 23 are provided in the movable groove; specifically, one end of the limit spring 25 is connected to the bottom surface of the movable groove, and the other end is connected to the limit ball 23; One end of the right connecting part 22 is connected to the first transmission mechanism 4 in the armrest 83 located on the other side of the seat 82, and the other end of the right connecting part 22 is provided with a slot, and a spherical groove 24 is provided on the inner side of the slot; a through hole with an opening toward the limiting ball 23 is provided on the bottom surface of the spherical groove 24, and a push rod 26 is located in the through hole, and the push rod 26 is slidably arranged on the side wall of the spherical groove 24.

[0034] In actual use, the first transmission mechanism 4 located in the two armrests respectively drives the left connecting part 21 and the right connecting part 22 to rotate toward the center of the seat 82, so that the limiting ball 23 enters the slot of the right connecting part 22, and the limiting ball 23 is squeezed by the side of the slot of the right connecting part 22. At this time, the limiting spring 25 is compressed until the limiting ball 23 rotates into the spherical groove 24. The limiting spring 25 is no longer squeezed by the side of the slot of the right connecting part 22 and returns to a natural state, so that the limiting ball 23 is limitedly set in the spherical groove 24, completing the connection between the left connecting part 21 and the right connecting part 22, thereby achieving fixation of the patient's lower limbs; After use, the medical staff only needs to push the push rod 23b into the spherical groove 24 to squeeze the limiting ball 23 out of the spherical groove 24, and then rotate the right connecting part 22 to separate the left connecting part 21 and the right connecting part 22, so that the patient can leave the restraint chair body 8.

[0035] The structure of the second limb restraint rod 3 is the same as that of the first limb restraint rod 2 , and the second limb restraint rod 3 is located below the first limb restraint rod 2 and is used to fix the patient's legs. In practical applications, the second limb restraint rod 3 is connected to the first transmission mechanism 4 .

[0036] like Figure 1 , 16 As shown in Figure 17, the mounting frame 1 is sleeved on the seat 82; specifically, the lower surface of the mounting frame 1 is fixedly connected to the upper surface of the seat 82. In actual use, since the seat 82 is provided with a spring inside, when the patient sits on the upper surface of the mounting frame 1, the spring inside the seat 82 is compressed, and the mounting frame 1 moves downward, that is, the height of the mounting frame 1 is reduced, and then the bottom surface of the mounting frame 1 presses the massage mechanism 5 downward.

[0037] A first accommodating cavity 85 and a third accommodating cavity 87 which is not connected to the first accommodating cavity 85 are respectively provided inside the two armrests 83 .

[0038] Specifically, each first accommodating cavity 85 is provided with a first transmission mechanism 4, such as Figure 3-7 As shown, each first transmission mechanism 4 includes a rack 41 vertically disposed in the first accommodating cavity 85, and a first transmission assembly 42 meshingly connected with the rack 41; The upper end of the rack 41 is fixedly connected to the connecting plate on the side of the installation frame 1 , and the lower end of the rack 41 is connected to the first transmission assembly 42 .

[0039] The first transmission assembly 42 includes a first gear rod 42a, a first transmission unit 42b, a second gear rod 42c and a transmission gear 42d; The first gear rod 42a and the second gear rod 42c are arranged horizontally, and the first gear rod 42a is located above the second gear rod 42c; the first gear rod 42a and the second gear rod 42c have the same structure, and one end of each gear rod is provided with a gear. When in use, the first gear rod 42a is rotatably arranged in the first accommodating cavity 85.

[0040] The first transmission unit 42b includes a first upper gear column 42b-1, a first lower gear column 42b-2, and a first transmission belt 42b-3 sleeved on the first upper gear column 42b-1 and the first lower gear column 42b-2; Specifically, the first upper gear column 42b-1 and the first lower gear column 42b-2 have the same structure, one end of which is rotatably connected to the inner wall of the first accommodating cavity 85, and the other end is provided with a gear. In addition, a rotating column for connecting to the first transmission belt 42b-3 is fixedly provided on the outer side of the gears of the first upper gear column 42b-1 and the first lower gear column 42b-2.

[0041] In actual use, one end of the first gear rod 42a with a gear is meshed with the gear of the first upper gear column 42b-1, and the other end passes through the first accommodating cavity 85 and the leg stop plate on the same side, and is fixedly connected to the left connecting portion 21; wherein the first gear rod 42 is rotatably connected to the inner wall of the first accommodating cavity 85; One end of the first upper gear column 42b-1 passes through the inner wall of the first accommodating chamber 85 and is located in the third accommodating chamber 87, and the gear on the other end is meshed and connected with the first gear rod 42a, and the rotating column outside the gear is sleeved with the first transmission belt 42b-3; wherein, the first upper gear column 42b-1 is rotatably connected with the inner wall of the first accommodating chamber 85; Connected to the first lower gear column 42b-2 via a first transmission belt 42b-3; One end of the first lower gear column 42b-2 is rotatably connected to the inner wall of the first accommodating chamber 85, and the gear on the other end is meshed with the rack 41, and the rotating column outside the gear is sleeved with the transmission belt 42b-3; The second gear rod 42c has one end with a gear meshed with the rack 41 through the transmission gear 42d, and the other end passes through the first accommodating cavity 85 and the leg stop plate on the same side, and is connected to the left connecting portion of the second limb restraint rod 3; The shoulder fixing ring 6 is arranged on the chair back 81; The backrest 81 has a second receiving cavity 86 disposed therein. Fig.10 and 11 As shown, the second transmission unit 7 is arranged in the second accommodating cavity 86. In practical application, the shoulder fixing ring 6 is connected to the second transmission unit 7.

[0042] Specifically, the second transmission unit 7 includes a second upper gear rod 71 , a second middle gear rod 72 , a second lower gear rod 73 and a second transmission belt 74 .

[0043] The second upper gear rod 71 is horizontally arranged in the second accommodating cavity 86, and the second upper gear rod 71 passes through the second accommodating cavity 86 and is fixedly connected to the shoulder fixing ring 6 located at the upper end of the chair back 81; The second middle gear rod 72 is vertically disposed in the second accommodating cavity 86 and is located between the second upper gear rod 71 and the first accommodating cavity 85; thus, the upper end of the second middle gear rod 72 is meshedly connected with one end of the second upper gear rod 71 provided with a gear, and the lower end of the second middle gear rod 72 is meshedly connected with the second lower gear rod 63; The structure of the second lower gear rod 73 is the same as that of the first upper gear column 42b-1, one end of which is rotatably connected to the inner wall of the second accommodating cavity 86, and the other end is provided with a gear, and a rotating column for connecting with the second transmission belt 74 is fixedly provided on the outer side of the gear; One end of the second transmission belt 74 is sleeved on the rotating column outside the gear of the second lower gear rod 73, and the other end passes through the second accommodating cavity 86 and is located in the third accommodating cavity 87, and the second transmission belt 74 is sleeved on the end of the first upper gear column 52a.

[0044] Thus, the working principle of the first transmission assembly 42 provided in the embodiment of the present invention is: After the patient sits on the mounting frame 1, the mounting frame 1 descends due to the patient's own gravity, and the mounting frame 1 drives the racks 41 fixedly connected on both sides to move downward, and the transmission gear 42d and the first lower gear column 42b-2 meshing with the rack 41 rotate, so that the transmission gear 54 drives the second gear rod 42c to rotate, and then the second gear rod 42c drives the second limb restraint rod 3 to rotate 270° clockwise, and the first lower gear column 42b-2 drives the first upper gear column 42b-1 to rotate through the first transmission belt 42b-3, and then the first upper gear column 42b-1 drives the first limb restraint rod 2 to rotate 270° clockwise, at the same time, the first upper gear column 42b-1 drives the second lower gear rod 73 to rotate through the second transmission belt 74, and the second lower gear rod 73 drives the second upper gear rod 71 to rotate through the second middle gear rod 72, and then the second upper gear rod 71 drives the shoulder fixing ring 6 fixedly connected to it to rotate toward the side close to the patient's upper limb, thereby realizing rapid fixation of the patient's shoulder.

[0045] like Figure 7 , 16 As shown in 17 , the massage mechanism 5 includes an inflatable airbag 51 and a massage column 52 connected to the inflatable airbag 51 ; The inflatable airbag 51 is arranged below the mounting frame 1, and the top surface of the inflatable airbag 51 is fixedly connected to the bottom surface of the mounting frame 1. A mounting plate is arranged on the bottom surface of the inflatable airbag 51, and one end of the mounting plate is fixedly connected to the chair back 81, that is, the inflatable airbag 51 is located between the mounting frame 1 and the mounting plate. In this way, the mounting plate provides a supporting force for the inflatable airbag 51, so that when the mounting frame 1 moves downward under the patient's own gravity, the mounting frame 1 squeezes the inflatable airbag 51, so that the inflatable airbag 51 inflates the airbag column 52; The massage column 52 is fixedly disposed on the side of the leg groove 84, and the massage column 52 is connected to the inflatable airbag 51 through the inflatable tube 53 so as to massage the patient's legs.

[0046] In this way, when the mounting frame 1 is lowered by the patient's own weight, the inflatable airbag 51 is squeezed by the mounting frame 1, so that the gas in the inflatable airbag 51 enters the massage column 52 through the inflatable tube 53, so that the massage column 52 expands and squeezes the patient's legs, thereby fixing the patient's lower limbs. In actual use, if the patient struggles, causing the mounting frame 1 to shake up and down, the gas in the inflatable airbag 51 and the massage column 52 will flow back and forth, so that the massage column 52 can contract slightly when the patient struggles, and the small protrusions thereon can play a massage role, effectively relieving the patient's manic mood and promoting the stability of his psychological state.

[0047] In order to better fix the patient's upper limbs, wrist fixing rings 9 are respectively provided on the two armrests 83 .
