Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary devices, and in particular to a body position restraint device for critical emergency treatment. Background Art

[0002] Severely ill patients may lose their ability to control their bodies due to unconsciousness, coma, irritability, etc. If there are no adequate protective measures around the bed, the patient may easily fall from the bed. Falling out of bed may cause serious secondary injuries such as head injuries and fractures. The position restraint device can fix the patient in a suitable position on the bed to prevent the patient from falling out of bed due to body movement and ensure the patient's physical safety. At the same time, some seriously ill patients may experience abnormal mental states such as irritability and delirium due to impaired consciousness and side effects of drugs. In this state, the patient may unconsciously scratch his wounds and skin, causing wound infection, bleeding, etc. The position restraint device can restrain the patient's hand movements to prevent the patient from causing harm to himself.

[0003] The existing body position restraints in the process of critical emergency treatment mainly fix the patient's limbs by means of compression plates or straps. Although the firmness of the patient's limbs can be ensured, during the long-term restraint and fixation process, the compression plates or straps will compress the skin and blood vessels on the patient's body surface, causing the superficial veins to be squeezed, resulting in poor blood return, thereby causing local blood circulation disorders. Moreover, as the restraint and fixation time increases, the patient's nerve function may be affected due to ischemia and hypoxia at the restraint and fixation site, and the nerves begin to send pain signals and cause tingling, thereby reducing the comfort and safety of the patient's restraint and fixation.

[0026] See also Figure 2 The rotating mechanism 12 shown in the figure includes a fourth fixed plate 1201 fixedly connected to the side of the bed 1 away from the second restraining plate 3, the fourth fixed plate 1201 is rotatably connected to a rotating rod 1202, one end of the rotating rod 1202 is fixedly connected to a first bevel gear 1203, the side wall of the double-headed threaded rod 1104 is fixedly connected to a second bevel gear 1204, the first bevel gear 1203 and the second bevel gear 1204 are meshed with each other, and the other end of the rotating rod 1202 is fixedly connected to a rocker 1205; It should be noted here that: through the setting of the rotating mechanism 12, the rotation of the rocker 1205 drives the first bevel gear 1203 at one end of the rotating rod 1202 to rotate, thereby driving the double-headed threaded rod 1104 to rotate under the mutual meshing transmission action of the first bevel gear 1203 and the second bevel gear 1204.

[0027] See also Figure 8 The second connecting mechanism 13 shown in the figure includes a second connecting rod 1302 fixedly connected to the side of the driving plate 1102 close to the second binding plate 3, and the end of the second connecting rod 1302 away from the driving plate 1102 is fixedly connected to a connecting ball 1301, and the connecting ball 1301 is rotatably connected to the second binding plate 3; It should be noted here that: the second connection mechanism 13 is provided to make the second restraining plate 3 fit the inclination of the patient's legs, thereby ensuring the restraining and fixing effect on the patient's legs.

[0028] Working principle: During emergency treatment, when it is necessary to restrain the position of a critically ill patient to prevent the patient from falling from the bed 1 or self-harm due to impaired consciousness, drug side effects, etc., the patient is first laid on the bed 1, and the patient's two arms and legs are respectively placed between the first restraint plate 2 and the second restraint plate 3. Taking the restraint of the patient's legs as an example, after the patient's legs are placed between the first restraint plate 2 and the second restraint plate 3, according to the placement angle of the patient's legs, the first restraint plate 2 is adjusted to prevent the patient from falling from the bed 1 or self-harm due to impaired consciousness, drug side effects, etc. Rotate so that the first restraint plate 2 fits against the patient's legs. After the first restraint plate 2 fits against the patient's legs, the connecting ring 1002 is rotated. Under the threaded connection transmission action of the connecting ring 1002 and the first connecting rod 1001, the connecting ring 1002 moves closer to the bed 1. When one side of the connecting ring 1002 abuts against the side wall of the bed 1, the rotation of the connecting ring 1002 is stopped. Thus, under the abutment action of the connecting ring 1002, the position of the first restraint plate 2 after the rotation angle is limited. After the position of the first constraint plate 2 is defined, the first bevel gear 1203 at one end of the rotating rod 1202 is driven to rotate by rotating the rocker 1205, so that the double-headed threaded rod 1104 is driven to rotate under the mutual meshing transmission action of the first bevel gear 1203 and the second bevel gear 1204. During the rotation of the double-headed threaded rod 1104, the two adjacent second constraint plates 3 are driven to move away from each other under the threaded meshing transmission action of the two driving plates 1102 and the double-headed threaded rod 1104 and the guiding action of the driving hole 1101. During the movement of the two second constraint plates 3 away from each other, when the second constraint plates 3 abut against the patient's legs, the second constraint plates 3 are driven to rotate under the action of the tightening force and the rotation of the second connecting mechanism 13, so that the second constraint plates 3 fit the inclination of the patient's legs, thereby ensuring the effect of restraining and fixing the patient's legs. Then, by continuing to rotate the rocker 1205, the second constraint plates 3 and the patient's legs are pre-aggressively abutted. When the first restraint plate 2 and the second restraint plate 3 form a pre-impact with the patient's legs, the motor 604 is started to drive the push rod 602 to rotate. During the rotation of the push rod 602, each cam 603 will be synchronously driven to rotate. Since the two adjacent cams 603 are arranged at 90 degrees, during the rotation of each cam 603, several staggered cams 603 will rotate close to the first restraint plate 2, while the other staggered cams 603 will rotate away from the first restraint plate 2. During the rotation, the switch plate 502 will be pressed against each other, and thus, under the pushing action of each staggered cam 603 and the guiding action of the reset mechanism 7, the switch plate 502 will move closer to the patient's legs, so that the staggered switch plates 502 will be pressed against the patient's legs. After each staggered switch plate 502 has a certain pressing force on the patient's legs, the rotation of the motor 604 is stopped, so that under the pressing action of each staggered switch plate 502, the patient's body position is restrained, and under the locking action of the motor 604, the firmness of the fixation of the patient's limbs is guaranteed; After the patient's legs are restrained for a period of time, the motor 604 is started again to drive the cams 603 that are against the switching plate 502 to rotate away from the first restraining plate 2, so that the switching plates 502 that are against the patient's legs are moved away from the patient's legs under the spring action of the reset mechanism 7. At the same time, the other staggered cams 603 are driven to move closer to the first restraining plate 2, and then under the pushing action of the other staggered cams 603 and the guiding action of the reset mechanism 7, the other staggered switching plates 502 are pushed to move closer to the patient's legs. After the other staggered switching plates 502 have a moving and tight force against the patient's legs, the rotation of the motor 604 is stopped. Therefore, by staggered pushing of each switching plate 502, it is convenient to switch the position of the position restraint after the patient has been restrained for a period of time, thereby avoiding discomfort to the patient caused by long-term restraint at the same position, thereby improving the comfort and safety of the patient's position restraint fixation. And in the process of each switching plate 502 moving away from the patient, when the triangular plate 803 on the switching plate 502 abuts against the push rod 802, the interaction force between the push rod 802 and the triangular plate 803 and the guiding action of the telescopic mechanism 9 will push the switching plate 502 to move away from the push rod 802. When the triangular plate 803 passes over the push rod 802, the elastic action of the telescopic mechanism 9 will push the switching plate 502 to move closer to the push rod 802. Then, in the process of the switching plate 502 moving away from the patient, the triangular plate 803 will reciprocatingly abut against the push rod 802. Therefore, under the interaction force and the guiding and resetting action of the telescopic mechanism 9, the switching plate 502 is pushed to perform reciprocating lateral movement. Then, the reciprocating lateral movement of the switching plate 502 is used to rub the skin of the patient's restraint fixation site to a certain extent, thereby facilitating blood recovery at the patient's restraint fixation site and enhancing the patient's comfort.
