Description

Technical Field

[0001] The present invention relates to the technical field of medical restraint devices, and particularly to an easily adjustable restraint device for mental patients and a using method thereof. Background Art

[0002] Mental patients refer to those with brain function disorders caused by various external harmful factors, and their clinical manifestations are abnormal mental activities. Specifically, they show varying degrees of disorders in aspects such as perception, thinking, attention, memory, emotion, behavior, will intelligence, and consciousness. Due to mental activity disorders, patients distortedly reflect the objective reality, lose their social adaptability, or those who harm themselves or disrupt social order are generally called mental patients.

[0003] When doctors diagnose, treat, and transfer mental patients, they often encounter suddenly ill mental patients. Since mental patients cannot correctly distinguish reality from illusion and control their personal behaviors, they often cannot cooperate with medical staff normally, and are very likely to show restlessness, and may even act self-harmingly and attack medical staff. In the current prior art, generally, when medical staff diagnose, treat, and transfer mental patients, they will fix and restrain the patients on the bed or chair with straps. At this time, the freedom of the patients is greatly restricted, which is very likely to exacerbate the mental trauma of the patients; in addition, the use of beds and chairs has relatively high requirements for medical staff, and it is necessary to control the patients on the bed or chair in advance, which is not convenient for single-person operation. Therefore, there is an urgent need to find a device that can flexibly adjust and restrain mental patients, which will not restrict the behavior of mental patients when their state is stable, but can be remotely controlled in time for restraint once the state of mental patients gets out of control, and the forced restraint can be gradually released after the state of mental patients returns.

[0029] Embodiment 1: Figure 1As shown in the figure, a restraint device for mental patients that is easy to regulate includes a human body 1. A strap 5 is provided on the human body 1, and a strap lining 6 is provided on the inner side of the strap 5. The strap lining 6 is used to reduce the pressure exerted by the strap 5 on the human body 1. The strap 5 is a leather belt or a medical fixation belt with a flexible structure. Two sets of symmetrically distributed restraint components are provided on the strap 5. The restraint component includes a rope-receiving unit 3 for receiving the rope and a wrist-binding unit 2 for connecting the hand of the human body 1. The rope-receiving unit 3 and the wrist-binding unit 2 are connected by a rope 4. When not in use, the wrist-binding unit 2 is close to one side of the rope-receiving unit 3.

[0030] As Figures 2 - 5 shown, the wrist-binding unit 2 includes a wristband box 2-1. Two symmetrically distributed fixed curved rods 2-2 are provided on the wristband box 2-1. The fixed curved rods 2-2 are hinged with movable curved rods 2-3 through rivets 2-5. Wristband linings 2-7 for directly contacting the hand of the human body 1 are connected to the inner sides of the two fixed curved rods 2-2 and the two movable curved rods 2-3. The fixed curved rods 2-2 and the movable curved rods 2-3 are both connected to the wristband linings 2-7 through a plurality of uniformly distributed elastic bands 2-6. A lock tooth 2-4 is provided at one end of the movable curved rod 2-3 away from the rivet 2-5, and teeth are provided on the movable curved rod 2-3.

[0031] The wristband box 2-1 includes an arc plate 2-13. A magnet 10 is fixedly installed on the arc plate 2-13. Side plates 2-12 are respectively fixedly installed on both sides of the arc plate 2-13. The two side plates 2-12 are jointly connected with a bottom plate. The bottom plate is connected to the arc plate 2-13. The arc plate 2-13 is connected to the two fixed curved rods 2-2. A keyhole is provided on one side plate 2-12, and an insertion hole is provided on the bottom plate. The insertion hole is used in cooperation with the movable curved rod 2-3. A lock assembly is provided inside the wristband box 2-1.

[0032] The lock assembly includes two symmetrically distributed partitions 7-1, and the two partitions 7-1 are fixedly installed on the bottom plate of the wristband box 2-1. The two partitions 7-1 are commonly connected with a rotating shaft 2-8, and the rotating shaft 2-8 is connected to one end of the rope 4. The two ends of the rotating shaft 2-8 are respectively connected to the two side plates 2-12 through hinge supports. A toothed buckle plate 2-10 is rotatably installed on the two partitions 7-1. A lock hole 2-11 is set at the rotation center of the toothed buckle plate 2-10 and the partition 7-1. The key hole on one side plate 2-12 is concentric with the lock hole 2-11. An elastic spring is arranged between the tooth plate 2-10 and the partition 7-1, the first end of the elastic spring is fixedly mounted on the tooth plate 2-10, the second end of the elastic spring is fixedly mounted on the partition 7-1, the tooth plate 2-10 is provided with meshing teeth that cooperate with the teeth on the movable curved rod 2-3, the two tooth plates 2-10 are connected, a weak type spring 2-9 is arranged on a partition 7-1, the first end of the weak type spring 2-9 is fixedly mounted on the rotating shaft 2-8, and the second end of the weak type spring 2-9 is fixedly mounted on the partition 7-1.

[0033] The special key is used in conjunction with the lock hole 2-11, the special key is inserted into the lock hole 2-11, and the special key is turned to drive the toothed buckle plate 2-10 to rotate through the lock hole 2-11, and the meshing teeth on the toothed buckle plate 2-10 are disengaged from the teeth on the movable curved rod 2-3. The special key is pulled out, and the toothed buckle plate 2-10 is reset by the elastic spring body 1. At this time, the movable curved rod 2-3 rotates around the rivet 2-5, and the hand of the mentally ill patient is placed on the wristband lining 2-7, and then the distance of the movable curved rod 2-3 inserted into the insertion hole of the bottom plate is adjusted according to the thickness of the mentally ill patient's wrist to ensure precision. To improve the comfort of the wrist of the mentally ill patient, the teeth on the movable curved rod 2-3 are re-engaged with the meshing teeth on the tooth buckle plate 2-10. When the wrist of the mentally ill patient is close to the rope-collecting unit 3, the weak-type spring 2-9 is in a relaxed state, so that the rope 4 is wound around the rotating shaft 2-8 through the elastic force of the weak-type spring 2-9. When the mentally ill patient becomes ill, the wrist is far away from the rope-collecting unit 3. At this time, the weak-type spring 2-9 is in a taut state. The weak-type spring 2-9 makes the exposed part of the rope 4 always in a taut state, ensuring that the rope 4 will not affect the mentally ill patient when he is moving.

[0034] like Figures 6 - 10As shown, the rope winding unit 3 includes a rope winding box, on which a magnet cooperating with the magnet 10 on the arc plate 2-13 is provided. A winding assembly is arranged in the rope winding box, and a limiting assembly is installed on the winding assembly. The winding assembly includes two symmetrically distributed second partition plates 7-2. The two second partition plates 7-2 are fixedly installed in the rope winding box. The two second partition plates 7-2 are jointly connected with a second rotating shaft 3-8. Both ends of the second rotating shaft 3-8 are installed on the rope winding box through hinge supports. Strong hairspring springs 3-3 are arranged on both of the two second partition plates 7-2. One end of the strong hairspring spring 3-3 is fixedly installed on the second partition plate 7-2, and the other end of the strong hairspring spring 3-3 is fixedly installed on the second rotating shaft 3-8. The elasticity of the strong hairspring spring 3-3 is moderate, which can prevent hurting the patient under strong restraint. Hexagonal countersunk holes 8 are arranged at both ends of the second rotating shaft 3-8. The winding assembly further includes two symmetrically distributed connecting rods 3-5. The two connecting rods 3-5 are both connected with the second rotating shaft 3-8 through connecting rods. The other end of the rope 4 is connected with the second rotating shaft 3-8.

[0035] The limiting assembly includes a left gear 3-1 and a right gear 3-2. The offset angles of the teeth on the left gear 3-1 and the right gear 3-2 are opposite. The left gear 3-1 and the right gear 3-2 are both fixedly installed on the second rotating shaft 3-8. A second tooth catch plate 3-4 is arranged above both the left gear 3-1 and the right gear 3-2. One end of the second tooth catch plate 3-4 is rotatably installed with a third rotating shaft 3-11. The third rotating shaft 3-11 is fixedly installed in the storage box. A fixed seat 3-12 is arranged above the second tooth catch plate 3-4. The fixed seat 3-12 is fixedly installed in the rope winding box. A return spring 9 is arranged between the fixed seat 3-12 and the second tooth catch plate 3-4. The first end of the return spring 9 is fixedly installed on the second tooth catch plate 3-4, and the second end of the return spring 9 is fixedly installed on the fixed seat 3-12. A limiting tooth matching the left gear 3-1 is arranged on the second tooth catch plate 3-4 above the left gear 3-1, and a limiting tooth matching the right gear 3-2 is arranged on the second tooth catch plate 3-4 above the right gear 3-2.

[0036] The limiting assembly further includes a left electric switch 3-6 and a right electric Y switch 3-7. The left electric switch 3-6 and the right electric Y switch 3-7 can both be controlled by remote control. The left electric switch 3-6 is located on one side of the left gear 3-1 and is fixedly installed in the rope winding box. A left telescopic rod 3-9 is fixedly installed on the left electric switch 3-6. The left telescopic rod 3-9 is located below the second tooth catch plate 3-4; the right electric Y switch 3-7 is located on one side of the right gear 3-2 and is fixedly installed in the rope winding box. A right telescopic rod 3-10 is fixedly installed on the right electric Y switch 3-7. The right telescopic rod 3-10 is located below the second tooth catch plate 3-4.

[0037] When the strong spring spring 3-3 inside the rope collection box is in a tightened state, the rope 4 will not be wound around the second shaft 3-8, the left electric switch 3-6 and the right electric Y switch 3-7 are in a closed state, and the second shaft 3-8 cannot rotate. At this time, the rope 4 is mainly wound around the first shaft 2-8. Under the action of the patient's hand, the rope 4 will continue to extend and shorten, and the weak spring spring 2-9 will continue to tighten and relax; when the mentally ill patient becomes ill, the mentally ill patient's wrist is away from the rope collection unit 3, and the left electric switch 3-6 is started by remote control. The left electric switch 3-6 starts the left telescopic rod 3-9 to extend the left telescopic rod 3-9, and the clockwise rotation of the left gear 3-1 will not be restricted. The second shaft 3-8 rotates the left gear 3-1 clockwise under the action of the strong spring spring 3-3, and the rope 4 is quickly wound around the second shaft 3-8, and then the mentally ill patient's wrist is quickly restrained to the rope collection units 3 on both sides of the mentally ill patient through the rope 4 wound around the first shaft 2-8. The hand movement ability of the mentally ill patient is restricted. Since the right electric Y switch 3-7 is not started at this time, the right telescopic rod 3-10 is not extended, and the shaft 2 3-8 can only rotate clockwise. The hands of the mentally ill patient are restrained on both sides of the waist by the action of the strong spring 3-3, and cannot break free. Since the right gear 3-2 and the limit teeth on the tooth plate 2 3-4 above the right gear 3-2 cooperate with the right gear 3-2, the rope 4 can only achieve one-way contraction movement, ensuring that the mentally ill patient's physical strength is slowly exhausted under the contraction action of the strong spring 3-3, thereby gradually restraining the mentally ill patient's ability to move, which can better reflect humanistic care; when the mentally ill patient returns to normal, turn off the left electric switch 3-6 and start the right electric Y switch 3-7, insert the hexagonal wrench into the hexagonal countersunk hole 8 and rotate it counterclockwise to loosen the rope 4, and tighten the strong spring 3-3 again. When the strong spring 3-3 is tightened to a taut state, turn off the right electric Y switch 3-7.

[0038] Embodiment 2: An easily adjustable restraint device for mentally ill patients is used to restrain the feet of mentally ill patients, including a strap 5 and a group of restraint components installed on the strap 5. The specific structure of the restraint components is the same as that of embodiment 1. This device can be used simultaneously on the feet of mentally ill patients. The strap 5 is fixedly bound to one ankle of the mentally ill patient, and then the wrist unit 2 in the restraint component is fixed to the other ankle of the mentally ill patient. The two groups of restraint components on the waist can be used simultaneously to continue to tighten and restrain the mentally ill patient.

[0039] Embodiment 3: An easily adjustable restraint device for mentally ill patients, which limits the range of movement of the mentally ill patients, comprises a strap 5 and a group of restraint components installed on the strap 5. The specific structure of the restraint components is the same as that of embodiment 1. This device fixes the strap 5 at a position in the room, and binds the wrist unit 2 in the restraint component to the wrist of the mentally ill patient, thereby limiting the movement of the mentally ill patient to a certain range in the room.

[0040] A method for using a restraint device for mental patients that can be easily regulated. With the permission of the patient's guardian, the specific usage method is as follows: Step 1: Check the rope retraction unit 3 to ensure that both the left electric switch 3-6 and the right electric Y switch 3-7 are in the off state, and the strong spring 3-3 is in a taut state; Step 2: When the mental patient is in a stable state, tie the strap 5 with the restraint component around the patient's waist and take good fixation measures; Step 3: Remove the wrist restraint unit 2 adsorbed on the rope retraction unit 3, then open the wrist restraint unit 2 and fasten it to the left and right wrists of the mental patient respectively; Step 4: When the mental patient is in a normal state, the patient moves their hands, and the weak spring 2-9 retracts the rope 4. When the mental patient is in an abnormal state and needs to be restrained, the left electric switch 3-6 is remotely controlled to open, and the patient's hands will only gradually retract to both sides of the waist under the action of the strong spring 3-3; Step 5: When the mental patient's condition has recovered appropriately, the patient can be transferred to the bed or a safe location, and the right electric Y switch 3-7 is remotely controlled to open. The patient's arms can gradually move, and the patient's condition is observed. If the condition does not continue to improve, the right electric Y switch 3-7 should be closed again; Step 6: When the mental patient has recovered to a normal state, the left electric switch 3-6 can be closed, and the right electric Y switch 3-7 can be opened again. At the same time, the strong spring 3-3 can be tightened again using an Allen wrench, and the restraint state of the mental patient will also be released; Step 7: When the mental patient's condition relapses, steps 4-6 can be repeated to restrain the mental patient again.

[0041] In addition, it should be noted that for the specific embodiments described in this specification, the shapes and names of the components can be different. The above structures and usage methods of the present invention have obtained the permission of the patient's guardian.
