Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a restraint chair for psychiatric nursing. Background Technology

[0002] During psychiatric care, patients may exhibit resistance, agitation, or aggressive behavior due to the specific circumstances of their condition. These behaviors may not only harm the patient but also pose a threat to medical staff or other patients. Therefore, in psychiatric nursing, it is often necessary to use protective restraint devices such as restraint chairs to limit the patient's range of motion and ensure their safety during treatment.

[0003] Traditional restraint chairs used in psychiatric care typically only restrain the patient's wrists and legs. Because the wrists are relatively flexible, if only the wrists are fixed, the patient may try to escape the restraint by twisting or struggling, resulting in poor restraint effectiveness. In addition, the chairs are complex in structure and inconvenient to operate. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing restraint chairs for psychiatric nursing usually only restrain the patient's wrists and legs, resulting in poor restraint effect and complex structure. Therefore, we propose a restraint chair for psychiatric nursing.

[0005] To achieve the above objectives, this application adopts the following technical solution: a restraint chair for psychiatric nursing, comprising a seat, a backrest fixed to one side of the seat, a leg rest fixed to the other side of the seat, armrests fixed to both sides of the seat, a fixed seat fixed to the top of the armrest, a fixed plate rotatably connected to the top of the fixed seat via a pivot, an upper housing fixed to both ends of one side of the fixed plate, and a lower housing fixed to both ends of one side of the fixed seat, a screw threadedly connected to the inside of the lower housing, a limit block fixed to one end of the screw inside the lower housing, the limit block being elliptical in shape, a knob fixed to the other end of the screw, movable plates slidably connected to both sides inside the lower housing, a locking block fixed to the top of the movable plate, and slots for engaging with the locking blocks at both ends of the upper housing.

[0006] Preferably, limit rods are fixed on both sides inside the lower housing, and a limit groove is provided on the surface of the movable plate to cooperate with the limit rods.

[0007] Preferably, a return spring is fixed on both sides inside the lower housing, and the other end of the return spring is fixed to the moving plate.

[0008] Preferably, the difference between the maximum and minimum diameters of the limiting block is greater than the diameter of the card block inserted into the card slot.

[0009] Preferably, a gasket is slidably connected to the surface of the screw, and the gasket is made of rubber.

[0010] Preferably, a restraint strap is fixed to one side of both the backrest and the leg rest, and a connecting shell that works in conjunction with the restraint strap is fixed to the other side of both the backrest and the leg rest.

[0011] Preferably, both the fixing base and the fixing plate have arc-shaped grooves inside that fit the arm, and both the fixing base and the fixing plate have soft pads inside.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, the patient's arm is placed in the arc-shaped groove inside the fixing base, and the fixing plate is rotated so that the upper and lower housings are on the same horizontal plane. At the same time, the locking block is located inside the upper housing. Then, the knob is turned so that the screw drives the limiting block to rotate and presses the moving plate. The moving plate will drive the locking block to insert into the slot and fix the upper housing, thereby fixing the patient's entire forearm. This effectively prevents the patient from making self-harm or attacking others. Fixing the forearm restricts the large range of arm movement and reduces the possibility of the patient using the arm as a tool or weapon for dangerous behavior. At the same time, the operation process is simple and highly practical. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Example 1

[0022] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a restraint chair for psychiatric nursing, including a seat 1, a backrest 2 fixed to one side of the seat 1, a leg rest 3 fixed to the other side of the seat 1, armrests 4 fixed to both sides of the seat 1, a fixed seat 5 fixed to the top of the armrests 4, a fixed plate 6 rotatably connected to the top of the fixed seat 5 via a pivot, an upper shell 7 fixed to both ends of one side of the fixed plate 6, a lower shell 8 fixed to both ends of one side of the fixed seat 5, a screw 9 threadedly connected inside the lower shell 8, a limit block 10 fixed to one end of the screw 9 inside the lower shell 8, the limit block 10 being elliptical in shape, a knob 11 fixed to the other end of the screw 9, a movable plate 12 slidably connected to both sides inside the lower shell 8, a locking block 13 fixed to the top of the movable plate 12, and a locking groove 14 for cooperating with the locking block 13 being opened at both ends of the upper shell 7.

[0023] Those skilled in the art will understand that by placing the patient's arm in the arc-shaped groove inside the fixing base 5 and rotating the fixing plate 6 so that the upper housing 7 and the lower housing 8 are on the same horizontal plane, and simultaneously positioning the locking block 13 inside the upper housing 7, then turning the knob 11 causes the screw 9 to rotate the limiting block 10 and press against the moving plate 12. The moving plate 12 will then drive the locking block 13 to insert into the slot 14, fixing the upper housing 7, thereby fixing the patient's entire forearm. This more effectively prevents the patient from making self-harm or attacking others. Fixing the forearm restricts the large range of motion of the arm, reducing the possibility of the patient using the arm as a tool or weapon for dangerous behavior. At the same time, the operation process is simple and highly practical.

[0024] Example 2

[0025] Reference Figure 3 and Figure 4 As shown in this embodiment: limit rods 15 are fixed on both sides inside the lower housing 8, and a limit groove 16 is opened on the surface of the moving plate 12 to cooperate with the limit rods 15. A return spring 17 is fixed on both sides inside the lower housing 8, and the other end of the return spring 17 is fixed to the moving plate 12. The difference between the maximum diameter and the minimum diameter of the limit block 10 is greater than the diameter of the card block 13 inserted into the card slot 14. A washer 18 is slidably connected to the surface of the screw 9. The material of the washer 18 is rubber.

[0026] Those skilled in the art will understand that the structure of the limiting rod 15 and the limiting groove 16 can improve the stability of the moving plate 12 during movement. The rebound force of the return spring 17 can pull the moving plate 12 and drive the locking block 13 out of the slot 14 when the medical staff turns the knob 11 to rotate the screw 9 and the limiting block 10 away from the moving plate 12, making it easier to release the fixing plate 6. Due to the elliptical shape of the limiting block 10, the difference between its maximum and minimum diameters is greater than the diameter of the locking block 13 inserted into the slot 14, which can ensure that the moving distance of the moving plate 12 can allow the locking block 13 to be released from the slot 14. The rubber material of the gasket 18 can make the knob 11 more secure to the lower housing 8.

[0027] Example 3

[0028] Reference Figure 2 As shown in this embodiment: a restraint strap 19 is fixed on one side of the backrest 2 and the leg rest 3, and a connecting shell 20 that works with the restraint strap 19 is fixed on the other side of the backrest 2 and the leg rest 3. The interior of the fixing seat 5 and the fixing plate 6 is provided with an arc-shaped groove designed to fit the arm, and the interior of the fixing seat 5 and the fixing plate 6 is provided with a soft pad 21.

[0029] Those skilled in the art will understand that by providing adjustable restraints such as restraint straps 19 and connecting shells 20 at the backrest 2 and leg rest 3, in conjunction with the fixing seat 5 and fixing plate 6, the patient's arms, chest, and legs can be restrained, reducing their struggling movements. This method can accommodate patients of different body types. When the restraints on the patient's arms are released, the restraints on the chest and legs allow the patient to move their upper limbs within a certain range, such as eating and drinking, thus improving their quality of life. By providing soft material in the arc-shaped grooves inside the fixing seat 5 and fixing plate 6, excessive injury to the patient's body can be avoided when they struggle.

[0030] The specific steps for using this psychiatric nursing restraint chair are as follows:

[0031] First, by placing the patient's arm in the arc-shaped groove inside the fixation base 5 and rotating the fixation plate 6, the upper housing 7 and the lower housing 8 are placed on the same horizontal plane, and the locking block 13 is placed inside the upper housing 7. Then, the knob 11 is turned to make the screw 9 drive the limiting block 10 to rotate and press the moving plate 12. The moving plate 12 will drive the locking block 13 to insert into the slot 14 and fix the upper housing 7, thereby fixing the patient's entire forearm.

[0032] Second, when it is necessary to release the fixation plate 6, the rebound force of the return spring 17 can pull the moving plate 12 and drive the locking block 13 out of the slot 14 when the medical staff turns the knob 11 to rotate the screw 9 and the limiting block 10 away from the moving plate 12, so as to facilitate the release of the fixation plate 6.

[0033] Thirdly, by setting adjustable restraint straps 19 and connecting shells 20 at the backrest 2 and leg rest 3, in conjunction with the fixing seat 5 and fixing plate 6, the patient's arms, chest, and legs can be restrained, reducing their struggling movements. It can also accommodate patients of different body types. When the restraint at the patient's arms is released, the restraint at the chest and legs can allow the patient to move their upper limbs within a certain range, such as eating and drinking, thus improving their quality of life. By setting soft material in the arc-shaped groove inside the fixing seat 5 and fixing plate 6, excessive damage to the body can be avoided when the patient struggles.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
