[0002] When examining a person (patient), the examination needs to be done in a lying position. When examining the body, sometimes the time is too long and the patient is prone to move around, thus affecting the examination effect. There is a method of restraint, which is generally to set a restraint belt on the bed to fix the patient's body. If the restraint force is too large, it is easy to cause physical discomfort to the patient. If the restraint force is too small, it cannot play a restraining effect, which still affects the examination effect. For some examinations that require people to be in a calm state, that is, people cannot be too nervous, the current use of restraint devices is even more unfavorable for doctors to perform medical work, and traditional restraint belts are usually fixed on the bed, which is not convenient for patients of different body shapes to use.

[0046] The bed body 6 is provided with a mattress 61, and the bed body 6 and the mattress 61 are provided with corresponding holes 63. The end of the restraint belt 9 opposite to the sliding seat extends above the mattress 61 through the hole 63, and the end of the restraint belt 9 opposite to the sliding seat is provided with an adjustment buckle. Multiple restraint belts 9 can be provided, and the restraint boxes 71 corresponding to the number of restraint belts 9 can be increased or decreased in the sliding groove 62 to achieve the effect of restraining more or less parts of the patient. In combination with the hole 63, the effect of restraining different body shapes and different parts can be achieved.

[0047] A patient restraint method based on a restraint bed as described above, the steps are as follows:

[0048] S1, pass the fixing screw 51 through the bed frame at one end of the bed body 6, then connect the fixing plate 53 to the fixing screw 51 from the rear side of the bed frame through the connecting port 54, and tighten the nut 55 to fix it, thereby fixing the head restraint device 8;

[0049] S2. Adjust the position of the restraint box 71 in the sliding slot 62 according to the body shape of the person (patient), and at the same time extend the restraint belt 9 from the hole 63 to above the mattress 61;

[0050] S3, after the person (patient) lies on the mattress 61, the height of the head cover 1 is adjusted through the adjustment mechanism so that the head cover 1 is fixedly restrained corresponding to the patient's face, and the restraint belt 9 is tied to the patient's limbs and torso through the adjustment buckle;

[0051] S4. During the treatment, when the person (patient) moves slightly, the restraint belt 9 drives the sliding seat to compress the spring 74. If the range of movement is small, there is a certain amount of space for movement due to the compression range of the spring 74. The contact 1 76 and the contact 2 77 do not contact each other, and the restraint belt 9 is relatively loose to ensure the comfort of the patient.

[0052] S5. When a person (patient) is moving due to gravity, that is, when the movement is more intense, the sliding seat drives contact 1 76 and contact 2 77 to contact and energize through trigger column 73, and then the controller uses the power supply to make electromagnet 72 work to absorb the iron block of the sliding seat, so that the restraint belt 9 is tightened, the restraint force is increased, and then the restraint belt 9 is pulled to restrain the patient's limbs and torso.

[0053] A head restraint device, a head restraint device 8 as described above, which is convenient for adjusting and restraining a patient's head and has a high degree of comfort.

[0054] A body restraint device, an adaptive body restraint device 7 as described above, which can adjust the restraint strength according to the patient's activity level.

[0055] When the device is in use, the fixing screw 51 is passed through the bed frame, and then the fixing plate 53 is connected to the fixing screw 51 from the back of the bed frame through the connecting port 54, and the nut 55 is tightened to fix it, thereby fixing the device; a control switch button electrically connected to the motor 35 is set on the mounting plate 34, and the support block 4 is adjusted by the bolt 41 according to the patient's condition to adjust it to a comfortable height for the patient. The patient's head lies on the pillow 44, and the adjusting screw 32 is driven by the motor 35 to rotate, so that the threaded port 12 drives the head cover 1 to move up and down, so that the head cover 1 can be more accurately attached to the head, and the head is protected by the protective cotton 2 inside the head cover 1, and the mouth and nose are placed in the mouth and nose placement port 22 so that the patient can breathe, and the ice compress eye mask 21 is attached to the eyes to relieve and cool the glasses, thereby improving comfort, thereby restraining the head while protecting it. The restraint belt 9 is extended from the hole 63 onto the mattress 61 in advance, and the restraint belt 9 is used to fix the patient's limbs and torso. When the patient is not moving vigorously, he will only be subject to a relatively small restraining force from the elastic force of the spring 74. When the patient moves vigorously, the contact between the contact 1 76 and the contact 2 77 activates the electromagnet 72, causing the electromagnet 72 to absorb the iron block, thereby increasing the restraining force of the restraint belt 9.

[0056] The present invention effectively improves the comfort of patients when they are restrained on the hospital bed, and can timely increase the restraint strength when the patient has strenuous activities. It can also be used for patients of different body shapes and sizes, and the number of restraint belts 9 can be increased or decreased according to different parts of the patient.

[0057] Especially suitable for use with psychiatric patients.

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

The electromagnet (72), the contact 1 (76), the contact 2 (77) and the power supply are respectively connected to the controller. The fixed end of the restraint belt (9) passes through the slot (75) and is fixedly connected to the sliding seat.

8. An induction restraint method for an induction restraint bed according to any one of claims 1 to 7, characterized in that: The steps are as follows: S1, passing the fixing screw 51 through the bed frame at one end of the bed body (6), and then connecting the fixing plate (53) to the fixing screw (51) from the rear side of the bed frame through the connecting port (54), and tightening the nut (55) to fix it, thereby fixing the head restraint device (8); S2, adjusting the position of the restraint box (71) in the sliding groove (62) according to the body shape of the person, and extending the restraint belt (9) above the mattress (61); S3, after the person lies on the mattress (61), the height of the head cover (1) is adjusted through the adjustment mechanism so that the head cover (1) is fixedly restrained corresponding to the patient's face, and the restraint belt (9) is tied to the patient's limbs and trunk through the adjustment buckle; S4. When the person moves slightly, the restraint belt (9) drives the sliding seat to compress the spring (74). If the range of movement is small, a certain amount of space is left for movement due to the compression range of the spring (74). The contact point 1 (76) and the contact point 2 (77) do not contact each other, and the restraint belt (9) is relatively loose to ensure the comfort of the patient. S5. When the person is moving due to gravity, the sliding seat drives the contact point 1 (76) and the contact point 2 (77) to contact and energize through the trigger column (73), and then the controller uses the power supply to make the electromagnet (72) work to absorb the iron block of the sliding seat, so that the restraint belt (9) is tightened, the restraint force is increased, and then the restraint belt (9) is pulled to restrain the patient's limbs and trunk, realizing inductive restraint.

9. A head restraint device, characterized in that: A head restraint device (8) as claimed in any one of claims 1 to 5, which is convenient for adjusting and restraining a patient's head and has a high degree of comfort.

10. A body restraint device, characterized in that: An adaptive body restraint device (7) as claimed in any one of claims 6 to 8, the restraint strength of which can be adjusted according to the patient's activity level.
