Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a patient protection device. Background Art

[0002] In the field of clinical treatment of psychiatry, mental illness, also known as mental illness, refers to a disease in which the brain is dysfunctional under the influence of various biological, psychological and social environmental factors, resulting in different degrees of disorders in mental activities such as cognition, emotion, will and behavior as clinical manifestations. At present, when a patient is ill, the patient will threaten his own life and a protective structure is needed to restrict limb movement. However, when fixing the patient, due to the strong resistance consciousness of some patients, it is difficult for medical staff to drag the patient to a bed surface higher than the ground. Although the utility model patent with the authorization announcement number CN215229425U discloses a safety protection structure for psychiatric patients, it can drive the bottom plate to rise and fall along the support plate when the patient's resistance consciousness is strong and it is difficult for medical staff to drag the patient to a bed surface higher than the ground, so as to achieve the driving extension plate to fit with the ground, so as to facilitate medical staff to move the patient to the upper surface of the bed board for fixing. However, since the protective structure used to restrain the patient on it does not have an adjustment function, the height of each patient is different, which brings inconvenience to the restraint process and affects the stability of the restraint protection. Utility Model Content

[0003] In view of the above problems, the purpose of the present utility model is to provide a patient protection device to solve the problem that the protection structure cannot be adjusted according to the different heights of patients.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is: a patient protection device, including a bed body, a motor 1 and a screw rod 1 are installed at the inner end of the bed body, and an operation panel is installed at the outer end thereof, and the output end of the motor 1 is connected to the end of the screw rod 1, a lifting frame is installed on the screw rod 1, a motor 2 and a screw rod 2 are installed at the inner end of the lifting frame, and the output end of the motor 2 is connected to the end of the screw rod 2, a moving seat 1 and a moving seat 2 are installed on the screw rod 2, and the moving seat 1 and the moving seat 2 are both slidably connected to the moving groove provided on the outer side of the lifting frame via the pulley installed on the inner side thereof, and the moving seat 1 and the moving seat 2 are ..., and the moving seat 1 and the moving seat 2 are slidably connected to the moving groove provided on the outer side of the lifting frame, and the moving seat 1 and the moving seat 2 are slidably connected to the moving groove provided on the outer side of the lifting frame, and the moving seat 1 and the moving seat 2 are slidably connected to the moving groove provided on the outer side of the lifting frame, and the moving seat 1 and the moving seat 2 are slidably connected to the moving groove provided A fastener A is installed on the seat one, and fastener A is buckled with fastener B. The fastener B is connected to one end of the restraint belt one through an adjustment ring installed thereon, and the other end of the restraint belt one is connected to one end of a restraint glove, and the other end of the restraint glove is connected to a limiting belt. A fastening bolt and a fixing plate are set on the movable seat two, a protection pad is installed on the fixing plate, and a restraint belt two is installed on the protection pad, and one end of the restraint belt two is connected to the fastener A, and the other end is connected to the adjustment ring installed on the fastener B through a sleeve. The lifting frame is installed on the side end of the bed board, and a lifting slot is opened on the bed body.

[0005] The beneficial effects of the present invention are as follows: through the present invention, not only the height of the bed board can be adjusted, thereby increasing the convenience for medical staff to drag the patient onto the bed board for restraint, but also, because the present invention can also adjust the restraint position and distance of the hand restraint structure and the leg restraint structure, it can adapt to the restraint and fixation of patients of different heights, increase the fit and stability of the restraint protection, and prevent patients from self-injury or hurting others.

[0006] To raise or lower the bed:

[0007] As a further improvement of the above technical solution: a motor is installed at each of the four corners of the bottom of the inner end of the bed, and the lifting grooves vertically opened on both sides of the front and rear ends of the bed are connected to a screw rod, and there are two lifting frames, which are horizontally installed at the left and right ends of the bed respectively.

[0008] The beneficial effect of this improvement is that, by setting up the motor 1, when the motor 1 is started, the screw rod 1 can drive the lifting frame and the bed board to move up and down on the bed body.

[0009] To move the mobile seat 1 / mobile seat 2 horizontally:

[0010] As a further improvement of the above technical solution: the number of the motor 2 and the screw rod 2 are both four, the four motors 2 are respectively installed in pairs at the middle position of the inner ends of the two lifting frames, and the four screw rods 2 are respectively installed in pairs at the front and rear parts of the inner ends of the two lifting frames, and the moving seat 1 is connected to the front end screw rod 2, and the moving seat 2 is connected to the rear end screw rod 2.

[0011] The beneficial effect of this improvement is that by setting up the second motor, when the second motor is started, the second screw rod can drive the first moving seat / the second moving seat to move horizontally on the lifting frame.

[0012] In order to restrict the outward expansion of the patient's hand and adjust the length of the limiting belt:

[0013] As a further improvement of the above technical solution: the two ends of the limiting belt are respectively connected to the two restraining gloves, and an adjustment ring is set on the limiting belt.

[0014] The beneficial effects of this improvement are as follows: by setting up the limiting belt, when the restraining gloves are worn on the patient's hands, the limiting belt can prevent the patient's hands from expanding outwards; by setting up the adjusting ring on the limiting belt, the adjusting ring can be moved or the limiting belt can be pulled to adjust the length of the use distance of the limiting belt.

[0015] To adjust the height and fix the position of the fixing plate:

[0016] As a further improvement of the above technical solution: the fastening bolt is screwed and set on the outer side of the second moving seat, and the fixing plate is set on the upper end of the second moving seat.

[0017] The beneficial effect of this improvement is that by unscrewing the fastening bolts outwards, the height of the fixed plate can be adjusted according to the height of the mattress laid on the bed board. When the adjustment is completed, the fastening bolts only need to be screwed inwards to press the fixed plate against the fixed plate, so that the fixed plate can be fixed in position.

[0018] To protect the patient's legs during restraint:

[0019] As a further improvement of the above technical solution: the number of the protection pads is two, and the two protection pads are respectively installed on the left and right sides of the middle of the fixed plate, and the protection pads are soft, breathable and elastic, and the installation position of the second restraint belt is located at the bottom of the protection pad.

[0020] The beneficial effect of this improvement is that by setting up the protection pad, when it is necessary to restrain the patient's legs, it is only necessary to wrap the patient's legs with the protection pad first, and then use the second restraint belt to wrap around the patient's legs at the outer end of the protection pad, so that the fasteners A and fasteners B respectively connected at both ends are fastened together, that is, in the process of restraining and fixing the patient's legs, the patient's legs will not be subjected to a strong sense of pressure and the patient's comfort will not be affected.
