[0001] The present invention relates to the technical field of restraint devices, in particular to a limb restraint device. Background Art

[0002] During an attack, patients with mania may experience extreme excitement, overactivity, aggressive behavior, self-harm, or harm to others. In order to prevent patients from causing harm to themselves or others, limb restraints are generally used clinically to limit patients' limb movements to ensure safety.

[0003] The limb restraint in the prior art is generally in the form of a strap, one end of which is tied to the patient's limb and the other end is tied to the bed frame, such as Chinese patent CN106726084B.

[0004] Although the above-mentioned restraint belts provide a certain amount of room for the patient's limbs to move while restraining them, since the patient's limbs are movable, there is still a risk that the patient may use facilities such as bed frames and walls to commit self-harm. At the same time, the strap-type fixing method is not only difficult to control the tightness, but also easy to strangle the patient's limbs during the patient's struggle. Summary of the invention

[0005] 1. Technical issues to be resolved In view of the deficiencies of the prior art, the present invention provides a limb restraint having the advantages of efficient restraint and comfortable cushioning.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment 1: See also Figure 1-Figure 4 A limb restraint comprises a lower liner 1 and an upper card seat 3, one side of which is hingedly connected by a hinge 2. Figure 1 As shown, a limb restraint space is formed between the lower liner 1 and the upper clamping seat 3 for restraining the patient's limbs.

[0022] Specifically, an arc-shaped pad 4 is laid and fixed on the arc-shaped surface of the inner bottom wall of the lower liner 1, an arc-shaped pressure plate 5 is movably provided in the upper clamping seat 3, and an elastic pad 6 is laid and fixed on the bottom of the arc-shaped pressure plate 5. In the present embodiment, the arc-shaped pad 4 and the elastic pad 6 are both silicone pads, which have good resilience, wear resistance and pressure resistance, and can not only provide cushioning protection, but also adapt to the limb shapes of different patients.

[0023] When in use, first place the patient's limbs on the arc pad 4, then close the upper seat 3. After closing, control the arc pressure plate 5 to move downward so that the arc pressure plate 5 is pressed on top of the patient's limbs, so that the patient's limbs can be stably wrapped and restrained. Compared with the traditional strap-type restraint, this not only makes the fixation method more comfortable, reduces the possibility of the patient breaking free, but also reduces the risk of self-harm.

[0024] In the present invention, the side of the lower liner 1 is connected to a cross bar 26 through a side rod and an adjuster, and the cross bar 26 is fixed to the bedside by a clamp at its end, so that the position of the entire lower liner 1 is fixed, which can effectively prevent the patient from using the bed frame or wall to self-harm.

[0025] This embodiment also provides a locking mechanism for locking the lower liner 1 and the upper card seat 3 to prevent opening. Specifically, Figure 2 As shown, an L-shaped locking rod 7 is fixedly installed on the side of the arc-shaped pressing plate 5, and the bottom end of the L-shaped locking rod 7 is movably inserted in a locking groove 9, which is provided on one side of the top of the lower liner 1. In addition, a side groove 8 for allowing the L-shaped locking rod 7 to move up and down is also provided on the inner side wall of the upper clamping seat 3; In this way, when the arc-shaped pressure plate 5 moves downward, it will also drive the L-shaped locking rod 7 to move downward, so that the bottom end of the L-shaped locking rod 7 is inserted into the locking groove 9. By inserting the bottom end of the L-shaped locking rod 7 in the locking groove 9, a locking effect can be achieved to prevent the upper clamping seat 3 from rotating to open. Conversely, when it needs to be opened, the arc-shaped pressure plate 5 is moved upward and the L-shaped locking rod 7 is disengaged from the locking groove 9.

[0026] In the present invention, the movement of the arc-shaped pressing plate 5 is controlled manually, specifically, as follows: Figure 2 As shown, a top cylinder 10 is fixedly installed on the top of the arc-shaped pressure plate 5, and an inner plate 11 is movably arranged in the top cylinder 10, and the inner plate 11 is supported by a support spring 12, and a screw rod 13 is rotatably installed on the top of the inner plate 11, and the screw rod 13 is screwed in a screw nut 14, and the screw nut 14 is fixedly installed on the top of the upper clamping seat 3; By twisting the screw rod 13, the screw rod 13 will move up and down under the action of the screw nut 14. The screw rod 13 moves up and down through the inner plate 11 to drive the arc-shaped pressing plate 5 to move up and down to adjust the position; Since the support spring 12 is provided, after the patient's limbs are restrained, when the patient struggles, the support spring 12 can provide buffering through its own compression to prevent the patient's limbs from being injured.

[0027] like Figure 4 As shown, two inflatable top airbag strips 27 are provided, fixed to the bottom of the arc-shaped pressure plate 5 and respectively located on both sides of the elastic pad 6, and the top tube 10 is connected to the two top airbag strips 27 through the upper connecting pipe; In the normal restraint state, the top airbag strip 27 is deflated; when the patient's limbs struggle violently, the arc-shaped pressure plate 5 is pushed upward and the support spring 12 is compressed. At this time, the air in the top tube 10 enters the top airbag strip 27 through the upper connecting pipe, thereby inflating the top airbag strip 27. The inflation of the top airbag strip 27 can not only play a role in buffering and protection, avoiding limb injuries of the patient due to violent struggle, but also further improve the restraint effect.

[0028] like Figure 4 As shown, two inflatable bottom airbag strips 28 are provided, fixed on the arc surface of the inner bottom wall of the lower liner 1 and located on both sides of the arc cushion 4; In addition, an inner cavity 29 is formed inside the lower liner 1, and a pull plate 30 is movably arranged in the inner cavity 29, the pull plate 30 is supported by a side support spring 31, and the side rod is fixedly installed on the pull plate 30, and the inner cavity 29 is connected with the two bottom airbag strips 28 through the lower connecting pipe; In the normal restraint state, the bottom airbag strip 28 is deflated; when the patient's limbs struggle violently, the side rods push the pull plate 30 to move, and the pull plate 30 moves to fill the air in the inner cavity 29 into the bottom airbag strip 28 through the lower connecting pipe, thereby inflating the bottom airbag strip 28. The inflation of the bottom airbag strip 28 can not only play a role in buffering and protecting, preventing the patient from limb injuries due to violent struggle, but also further improve the restraint effect; Although the upward movement of the arc-shaped pressure plate 5 provides a larger space for limb movement, the inflation of the top airbag strip 27 and the bottom airbag strip 28 can restrain the patient's limbs by "four points". In this way, although the patient's limbs can move, they will still be restrained and will not touch hard materials, making them less likely to be injured.

[0029] Embodiment 2: See also Figure 1 and Figure 5 Based on the first embodiment, this embodiment specifically provides a regulator structure, specifically, as Figure 5As shown, the regulator includes a pull rod 16, a movable plug 17 and a transverse cylinder 18. The end of the side rod is fixedly connected to the pull rod 16, and the end of the pull rod 16 is fixedly installed on the movable plug 17. The movable plug 17 is movably arranged in the transverse cylinder 18. The transverse rod 26 is fixedly installed at the other end of the transverse cylinder 18. The transverse cylinder 18 is filled with hydraulic oil, and an oil hole 20 is provided on the movable plug 17. When the patient struggles, the side rod can drive the pull rod 16 to move, and then pull the movable plug 17 to move. When the movable plug 17 moves, the hydraulic oil flows through the oil hole 20, thereby providing smooth damping. This not only reduces the impact force when the patient struggles violently, avoids joint injuries or fractures, and improves overall safety, but also can effectively consume the patient's strength, allowing the patient to gradually become tired after multiple attempts to struggle, and thus stabilize his emotions.

[0030] In this embodiment, the side rod is an elastic rod 15 that can produce a certain deformation, so that when the patient struggles, the elastic rod 15 can pull the pull rod 16 and the movable plug 17 to move.

[0031] The movable design of the movable plug 17 also facilitates the patient's limbs (such as arms) to adjust the posture without being restricted to one position all the time.

[0032] Embodiment three: See also Figure 5 , based on the first and second embodiments, in this embodiment, the interior of the horizontal cylinder 18 is separated by a partition 19 into an oil chamber and an air chamber, and the hydraulic oil is filled in the oil chamber; In addition, a tail rod 21 is fixedly installed on the side of the movable plug 17 facing the partition 19, and the tail rod 21 passes through the partition 19 and is fixedly connected to a piston 22; like Figure 1 and Figure 5 As shown, one side of the air cavity is connected to an air storage box 24 through an air inlet pipe 23, and a one-way air inlet valve is provided on the air inlet pipe 23; the other side of the air cavity is connected to an exhaust pipe 25, and a one-way exhaust valve is provided on the exhaust pipe 25; in this embodiment, aromatic gas, such as sweet orange flavor gas, lavender flavor gas, chamomile flavor gas, etc., is stored in the air storage box 24. The aromatic gas can stimulate the brain's limbic system through olfactory receptors, reduce the excitability of the sympathetic nerves, thereby relieving anxiety, lowering heart rate and soothing emotions, while reducing the patient's resistance behavior and reducing the mental stress caused by long-term restraint.

[0033] When the patient struggles, while driving the movable plug 17 to move, the tail rod 21 will also drive the piston 22 to move. Through the circular movement of the piston 22 and the exhaust pipe 25, the aromatic gas stored in the gas storage box 24 can be discharged, thereby assisting the patient's sedation and making it easier for the patient to calm down.

[0034] In this embodiment, the pull rod 16 and the cross tube 18, and the tail rod 21 and the partition plate 19 are sealed by sealing members to prevent gas and liquid leakage.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
