Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a restraint device for the treatment of psychiatric patients. Background Art

[0002] Due to the influence of diseases, psychiatric patients often suffer from symptoms such as disturbance of consciousness, restlessness, delirium, etc. These symptoms may lead to dangerous behaviors such as the patient pulling out the treatment tube by himself, self-harm, suicide or hurting others. Therefore, during the treatment process, special restraint devices are needed to ensure the safety of the patient and prevent him from being injured due to his own behavior or disturbance of consciousness.

[0003] Although some of the existing restraint devices for psychiatric patients can achieve the restraint of patients to a certain extent, it is often difficult to adjust the degree of restraint according to the patient's body type, and it may be difficult to completely restrain the patient when facing patients of different body types.

[0004] In summary, it has become a difficult problem that needs to be solved urgently in this field that some of the existing restraint devices for psychiatric patients are difficult to adjust the degree of restraint according to the patient's body type and may have problems in completely restraining the patient. Therefore, it is necessary to propose a restraint device for the treatment of psychiatric patients. Summary of the Invention

[0005] To solve the above problems, the present invention provides a restraint device for the treatment of psychiatric patients. By adjusting the extension of the output shaft of the telescopic member, the clamping situation of the clamping block on the patient's foot can be adjusted, so as to flexibly adapt to the body types of different patients and provide a more personalized restraint solution.

[0006] To achieve the above object, the technical solution of the present invention is as follows: A restraint device for the treatment of psychiatric patients includes a controller and a bottom plate. A chair seat with a hollow interior is fixedly connected to the top of the bottom plate. A chair back is fixedly connected to the top of the chair seat. Armrests are symmetrically and fixedly connected to both sides of the chair back. Auxiliary components for assisting in fixing the patient's feet are symmetrically arranged inside the chair seat.

[0007] The auxiliary component includes a telescopic member fixedly connected to the inner bottom wall of the chair seat. The output shaft of the telescopic member is coaxially fixedly connected with a pressing block. A pressing plate is fixedly connected to the side of the pressing block away from the output shaft of the telescopic member. The controller is used to control the telescopic movement of the output shaft of the telescopic member.

[0008] A number of first chutes and a number of second chutes are symmetrically opened on the inner bottom wall of the chair seat. First sliders are slidably fitted in the first chutes respectively, and second sliders are slidably fitted in the second chutes respectively. First connecting rods are symmetrically hinged to both sides of the pressing block. The ends of the first connecting rods away from the pressing block are respectively hinged to the tops of the first sliders adjacent to them.

[0009] A second link is hinged to one end of the first link away from the pressing block, and one end of the second link away from the first link is hinged to the adjacent second slider.

[0010] An extension rod is fixedly connected to the side wall of each second slider. The extension rods all penetrate through the side wall of the seat and extend outside the seat, and are slidably matched with the side wall of the seat. A protection component for protecting the patient's feet is symmetrically arranged inside the seat.

[0011] A hand fixing component for fixing the patient's hands is arranged on each armrest.

[0012] A foot fixing component for fixing the patient's feet is arranged on each extension rod.

[0013] The technical principle of the above solution is as follows:

[0014] Medical staff guide the patient to sit on the seat, fix the patient's hands through the hand fixing component, and then start the telescopic member through the controller. The output shaft of the telescopic member extends, driving the pressing block to move horizontally. The pressing block drives the first link to swing. The first link drives the adjacent first slider to slide along the first chute. At the same time, under the limitation of the first slider, it drives the adjacent second link to swing. The second link drives the adjacent second slider to slide along the second chute, driving the extension rod to extend outside the seat, and the extension rod drives the clamping block to extend together with it. The adjacent second sliders move towards each other under the guiding action of the second chute, so that the adjacent clamping blocks move towards each other to clamp the patient's feet. At the same time, the medical staff fix the patient's feet through the foot fixing component.

[0015] During the horizontal movement of the pressing block, it also drives the pressing plate to move horizontally, driving the protection component to protect the patient's feet.

[0016] The above solution has the following beneficial effects:

[0017] 1. In the present invention, by adjusting the extension of the output shaft of the telescopic member, the clamping condition of the clamping block on the patient's feet can be adjusted, so as to flexibly adapt to the body types of different patients and provide a more personalized restraint solution.

[0018] 2. In the present invention, by setting the auxiliary component and using the cooperation of the telescopic member, the pressing block, the pressing plate, the link and the slider, the device can effectively fix the patient's feet and prevent unnecessary movement or unnecessary injury.

[0019] 3. In the present invention, the addition of the hand fixing component further enhances the safety of the patient, ensures that the patient's hands are properly fixed during the use of the restraint device, and reduces the risk of accidents.

[0020] Furthermore, the hand fixing component includes a fixing block fixedly connected to the top of the armrest. There are several hand hinge blocks above the armrest, and the fixing block is hinged to the adjacent hand hinge block.

[0021] The adjacent hand hinge blocks are hinged to each other. A first electromagnet is detachably connected to the bottom of the hand hinge block and the top of the armrest, and the controller is used to control the magnetic force of the first electromagnet.

[0022] Beneficial effects: Through the hinge design between adjacent hand hinge blocks, the entire hand fixing component can flexibly adapt to the hand sizes of different patients, ensuring the stability and safety of the patient's hand during fixation.

[0023] Furthermore, the foot fixing component includes a clamping block fixedly connected to the end of the extension rod away from the second slider. There are several foot hinge blocks on one side of the seat, and the clamping blocks are all hinged to the adjacent foot hinge blocks, and the adjacent foot hinge blocks are hinged to each other.

[0024] Second electromagnets are detachably connected to both sides of the foot hinge block, and the controller is used to control the magnetic force of the second electromagnet.

[0025] Beneficial effects: The application of the second electromagnet provides a stable and reliable fixing force for the patient's feet. By adjusting the magnetic force through the controller, it can ensure that the patient's feet are firmly fixed when needed.

[0026] Furthermore, the protection component includes a pressing airbag fixedly connected to the inner bottom wall of the seat. Protection airbags are fixedly connected to the side walls of the clamping blocks, and the protection airbags are fixedly connected to the side walls of the adjacent foot hinge blocks. Several through holes are opened on the protection airbags, and the second electromagnets on the side of the foot hinge block close to the protection airbag extend outside the protection airbag through the adjacent through holes.

[0027] The protection airbags are all communicated with the pressing airbag, and the pressing airbag is located in the movement path of the adjacent pressing plate.

[0028] Beneficial effects: The design of the protection airbag provides additional safety protection for the patient's feet. When the movement amplitude of the patient's feet is too large, the protection airbag can provide buffering for the patient's feet and reduce the damage suffered.

[0029] Furthermore, pulse sensors are fixedly connected to the armrests, and signal lights are fixedly connected to the top of the backrest. The controller is used to receive the pulse signals sent by the pulse sensors and control the lighting and extinguishing of the signal lights based on the pulse signals.

[0030] Beneficial effects: Pulse changes can often reflect the patient's emotional state and physical condition. By controlling the lighting and extinguishing of the signal lights based on the pulse signals through the controller, instant feedback on the patient's state can be achieved.

[0031] Furthermore, elastic buffer layers are fixedly connected to one side of the fixing blocks.

[0032] Beneficial effects: The elastic buffer layers can absorb and disperse the impact force acting on the fixing blocks, thereby reducing the sense of compression and discomfort for the patient.

[0033] Furthermore, shoulder limiters are symmetrically and vertically slidably fitted on the side wall of the chair back.

[0034] Beneficial effects: The design of the shoulder limiters sliding vertically along the side wall of the chair back enables medical staff to adjust the height of the shoulder limiters according to the height and body type of the patient, thus achieving personalized customization and improving the adaptability and flexibility of the device.

[0035] Furthermore, a head limiter is vertically slidably fitted on the side wall of the chair back, and the bottom of the head limiter and the top of the shoulder limiter are both detachably connected.

[0036] Beneficial effects: By adjusting the head limiter, it can ensure that the patient's head can be effectively limited, further improving the adaptability and flexibility of the device.

[0037] Furthermore, anti-collision layers are fixedly connected to the inner side walls of the head limiter and the shoulder limiter.

[0038] Beneficial effects: The design of the anti-collision layers can significantly reduce the risk of injury caused by accidental collisions. In places such as the psychiatric department or the rehabilitation department, patients may suddenly move due to emotional fluctuations. The anti-collision layers can effectively slow down the impact on the head and shoulders caused by such sudden movements and protect the patients from injury.

[0039] Furthermore, straps are fixedly connected to the chair back.

[0040] Beneficial effects: The design of the straps can ensure that the patient remains stable in the restraint device, preventing the patient from suddenly standing up or falling down due to emotional fluctuations, thereby improving the overall safety.

[0041] The additional aspects and advantages of the present invention will be partly given in the following description, partly will become obvious from the following description, or will be understood through the practice of the present invention. Brief Description of the Drawings

Detailed Description of the Specific Embodiment

[0046] The following is a further detailed description through specific embodiments:

[0047] Embodiment 1:

[0048] As shown in Figure 1 , Figure 2 and Figure 3 : A restraint device for the treatment of psychiatric patients includes a controller and a bottom plate 1. A seat 2 with a hollow interior is bolted and fixedly connected to the top of the bottom plate 1. A backrest 3 is integrally formed on the top of the seat 2. A strap 4 is bolted and fixedly connected to the backrest 3. Armrests 5 are integrally formed symmetrically on both sides of the backrest 3. Shoulder limiting frames 6 are symmetrically and vertically slidably fitted on the side walls of the backrest 3. A head limiting frame 7 is vertically slidably fitted on the side wall of the backrest 3. The bottom of the head limiting frame 7 and the top of the shoulder limiting frame 6 are both detachably connected by a buckle. Anti-collision layers are fixedly adhered to the inner side walls of the head limiting frame 7 and the shoulder limiting frame 6. An auxiliary assembly for assisting in fixing the patient's feet is symmetrically provided inside the seat 2.

[0049] The auxiliary assembly includes a telescopic member bolted and fixedly connected to the inner bottom wall of the seat 2. The output shaft of the telescopic member is coaxially bolted and fixedly connected with a pressing block 8. A pressing plate 9 is integrally formed on the side of the pressing block 8 away from the output shaft of the telescopic member. The controller is used to control the telescopic movement of the output shaft of the telescopic member. In this embodiment, the telescopic member is selected as an electric telescopic rod.

[0050] A number of first chutes and a number of second chutes are symmetrically formed on the inner bottom wall of the seat 2. First sliders 10 are slidably fitted in the first chutes respectively. Second sliders 11 are slidably fitted in the second chutes respectively. First connecting rods 12 are symmetrically hinged on both sides of the pressing block 8. The ends of the first connecting rods 12 away from the pressing block 8 are respectively hinged to the tops of the first sliders 10 adjacent to them.

[0051] Second connecting rods 13 are respectively hinged to the ends of the first connecting rods 12 away from the pressing block 8. The ends of the second connecting rods 13 away from the first connecting rods 12 are respectively hinged to the second sliders 11 adjacent to them.

[0052] Extension rods 14 are integrally formed on the side walls of the second sliders 11. The extension rods 14 all penetrate through the side wall of the seat 2 and extend outside the seat 2 and are slidably fitted with the side wall of the seat 2. Protection assemblies for protecting the patient's feet are symmetrically provided inside the seat 2.

[0053] On the armrests 5, there are hand fixing components for fixing the patient's hands, and on the extension rods 14, there are foot fixing components for fixing the patient's feet.

[0054] The hand fixing component includes a fixing block welded to the top of the armrest 5. On one side of the fixing block, an elastic buffer layer is fixedly adhered. Above the armrest 5, there are several hand hinge blocks 15, and the fixing block is hinged to the adjacent hand hinge block 15.

[0055] The adjacent hand hinge blocks 15 are hinged to each other. At the bottom of the hand hinge block 15 and the top of the armrest 5, first electromagnets are detachably connected by screws, and the controller is used to control the magnetic force of the first electromagnets.

[0056] The foot fixing component includes a clamping block 17 welded to one end of the extension rod 14 away from the second slider 11. On one side of the seat 2, there are several foot hinge blocks 18. The clamping blocks 17 are all hinged to the adjacent foot hinge blocks 18, and the adjacent foot hinge blocks 18 are hinged to each other.

[0057] On both sides of the foot hinge block 18, second electromagnets are detachably connected by screws, and the controller is used to control the magnetic force of the second electromagnets.

[0058] The protection component includes a pressing airbag 20 fixedly adhered to the inner bottom wall of the seat 2. On the side walls of the clamping blocks 17, protection airbags 19 are fixedly adhered. The protection airbags 19 are all fixedly adhered to the side walls of the adjacent foot hinge blocks 18. Several through holes are opened on the protection airbags 19, and the second electromagnets on the side of the foot hinge block 18 close to the protection airbag 19 all extend outside the protection airbag 19 through the adjacent through holes.

[0059] The protection airbags 19 are all communicated with the pressing airbag 20, and the pressing airbag 20 is located in the movement path of the adjacent pressing plate 9.

[0060] The specific implementation process is as follows: The medical staff guides the patient to sit on the seat 2, wears the strap 4 for the patient, and adjusts the positions of the head limiting frame 7 and the shoulder limiting frame 6 according to the patient's body type, so that the patient's head and shoulders are respectively limited by the head limiting frame 7 and the shoulder limiting frame 6. Subsequently, the medical staff fixes the head limiting frame 7 and the shoulder limiting frame 6, and places the patient's hand on the armrest 5. The controller is used to make the first electromagnets on the hand hinge block 15 and the first electromagnets on the armrest 5 attract each other. During this process, the medical staff adjusts the position of the hand hinge block 15 according to the size of the patient's hand to ensure that the patient's hand is stably fixed on the armrest 5, and the fixation of the patient's hand is completed.

[0061] After the patient's hand is fixed, the medical staff starts the electric telescopic rod through the controller. The output shaft of the electric telescopic rod extends, driving the pressing block 8 to move horizontally. During the movement of the pressing block 8, it will drive the first connecting rod 12 to swing. As Figure 2 shown, the first connecting rod 12 will drive the adjacent first slider 10 to slide along the direction of the first chute. At the same time, the first connecting rod 12 drives the adjacent second connecting rod 13 to swing under the limiting action of the first slider 10 and the first chute. The second connecting rod 13 drives the adjacent second slider 11 to slide along the direction of the second chute, so as to drive the adjacent extension rod 14 to extend out of the seat 2.

[0062] During the extension process of the adjacent extension rods 14, under the limiting action of the second chute on the second slider 11, they move towards each other, driving the clamping blocks 17 welded to them to move towards each other to clamp the patient's feet. At this time, the medical staff controls the second electromagnets on both sides of the foot clamping block 17 to attract each other according to the patient's foot size to clamp the patient's feet.

[0063] During the horizontal movement of the pressing block 8, it will also drive the pressing plate 9 to move horizontally with it, squeezing the pressing airbag 20. After being squeezed, the pressing airbag 20 transports the gas inside it to the inside of the protection airbag 19, and the protection airbag 19 buffers and protects the patient's feet. Since the second electromagnets on the side of the foot hinge block 18 close to the protection airbag 19 all extend outside the protection airbag 19, sufficient space is provided for the expansion of the protection airbag 19. When the second electromagnets attract each other, the protection airbag 19 can normally buffer and protect the patient's feet.

[0064] By adjusting the extension of the output shaft of the telescopic member, the clamping condition of the clamping block 17 on the patient's feet can be adjusted, so as to flexibly adapt to the body types of different patients and provide a more personalized restraint solution.

[0065] Embodiment 2:

[0066] As shown in the appendix Figure 1 shown, the difference from Embodiment 1 is that pulse sensors 21 are embedded and installed on the armrests 5, and a signal lamp 22 is fixedly connected to the top of the backrest 3 by screws. The controller is used to receive the pulse signals sent by the pulse sensors 21 and control the on and off of the signal lamp 22 based on the pulse signals.

[0067] The specific implementation process is as follows: The medical staff sets a pulse threshold through the controller. When the patient's pulse rate is greater than the pulse threshold, the pulse sensor 21 sends a pulse signal to the controller, and the controller controls the signal lamp 22 to light up, prompting the medical staff that the patient's pulse is abnormal at this time, which is convenient for the medical staff to make timely responses.

[0068] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
