Description

Technical Field

[0001] The present invention belongs to the technical field of body restraint devices, and in particular relates to a protective restraint device for patients with mental disorders. Background Art

[0002] Due to the nature of their illnesses, patients with mental illnesses are often at risk of behavioral disorders, which may manifest as aimless agitation, unpredictable aggression, or severe self-harm. This poses a significant threat not only to the patient's own safety, but also to surrounding medical staff and other patients. Therefore, when implementing certain necessary physical therapies, especially interventions like electrical stimulation that require the patient to maintain a specific posture and high levels of cooperation, ensuring the safety and controllability of the treatment process is paramount.

[0003] However, the application of electric current during treatment may trigger tetanic contraction of the patient's muscles or a momentary startle reaction. If the patient moves significantly at this time, it is very easy to cause operational deviations, equipment displacement, and even lead to accidental physical injuries such as muscle strain, joint dislocation, and fracture. It will also seriously interfere with the accuracy of treatment parameters and treatment effects. In order to avoid these risks to the greatest extent and ensure that the treatment can be completed smoothly, accurately and safely, clinical practice generally requires that before conducting electrical stimulation treatment, specially trained medical staff use special, cushioned restraints or fixation devices to securely restrain the patient's limbs, shoulders and torso to the treatment bed.

[0004] In the Chinese patent with publication number CN109966151A, a mental monitoring intelligent drug delivery device for drug delivery protection of mental illness is mentioned, including a support frame for serving as a support, a reclining chair assembly for carrying mentally ill patients, a fastening device for restraining mentally ill patients, a drug delivery bottle device for mentally ill patients to take medicine, a brain wave monitoring system for monitoring mentally ill patients; and a rotating arm for fixing the drug delivery bottle device; the overall structural design of the invention is reasonable, which can effectively avoid the problem of a huge workload for medical staff when feeding mentally ill patients, and can be used for mentally ill patients at the time of illness, overcoming the problem of being unable to control mentally ill patients at the time of illness, and effectively reducing the risk of suffocation caused by patient resistance during medication, and is suitable for large-scale promotion.

[0005] During the application process, the applicant discovered that the above application had defects during use. The fastening device in the device is an airbag, which limits the patient's wrist, shoulder and head movements by inflating the airbag. However, relying solely on the airbag to limit the patient's limb extremities is not enough to completely limit the patient's movements. The patient's waist and torso can still perform violent movements, affecting the medical staff's treatment operations on the patient. Summary of the Invention

[0006] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a protective restraint device for patients with mental disorders to solve the problem that traditional therapeutic restraint devices for mental patients cannot stably restrain mental patients and are inconvenient for medical staff to operate.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0030] Example:

[0031] See also Figures 1-6 As shown, a protective restraint device for a patient with a mental disorder comprises:

[0032] A bed board 1 is provided with a plurality of chutes 2 on its side walls, an extension rod 4 being slidably connected to the end of the chutes 2, a first spring 3 being provided inside the chutes 2, one end of the first spring 3 being in contact with the inner wall of the chutes 2 and the other end being in contact with the end of the extension rod 4, and a side pad 7 being provided on the plurality of extension rods 4, the side pad 7 being made of a soft material and being deformable when squeezed;

[0033] A driving assembly is arranged at the bottom of the bed board 1;

[0034] a restraint assembly connected to the drive assembly and moving along the length direction of the bed board 1 under the action of the drive assembly, the restraint assembly comprising an electric telescopic rod 11 connected to the drive assembly, a second motor 12 fixedly mounted on one end of the electric telescopic rod 11, and a restraint belt 13 fixedly mounted on the output shaft of the second motor 12, the end of the restraint belt 13 being movably engaged with one end of the electric telescopic rod 11;

[0035] an auxiliary restraint assembly, connected to the restraint belt 13, for assisting in restraining the patient;

[0036] The controller 26 is connected to the bed board 1 and is used to control the actions of the driving component, the restraining component and the auxiliary restraining component.

[0037] As can be seen from the above, by arranging a driving component, a restraint component and an auxiliary restraint component under the bed board 1, when the user needs to restrain a mentally ill patient for treatment, the mentally ill patient can be placed on the bed board 1, and then the auxiliary restraint component can be placed at a suitable position on the patient's body. The controller 26 controls the electric telescopic rod 11 to shorten, and at the same time controls the output shaft of the second motor 12 to rotate. The restraint belt 13 will be wrapped around the output shaft of the second motor 12 and gradually shortened. The shortened restraint belt 13 compresses the first spring 3 through the expansion rod 4. As the expansion rod 4 retracts into the inside of the slide groove 2, the restraint belt 13 shortens and is gradually tied to the patient's body. As the restraint belt 13 shortens, the pressure of the restraint belt 13 on the auxiliary restraint component gradually increases. The auxiliary restraint component cooperates with the restraint belt 13 to stably clamp the patient's body. Multiple restraint components and auxiliary restraint components cooperate to limit the movement of the patient's body joints, which can effectively prevent the patient's body from shaking during treatment, making it convenient for medical staff to carry out subsequent treatment work.

[0038] See also Figure 5 As shown, the constraint assembly also includes an outer cylinder 14 fixedly mounted on the end of the constraint belt 13 and a telescopic block 15 slidably connected to the end of the outer cylinder 14. A second spring 16 is arranged inside the outer cylinder 14, and the two ends of the second spring 16 are respectively abutted against the ends of the two telescopic blocks 15. A card slot 17 is provided at the bottom of one end of the electric telescopic rod 11, and positioning grooves are provided at both ends of the card slot 17. The telescopic block 15 is clamped inside the positioning groove. A side groove communicating with the card slot 17 is provided on the side wall of the end of the electric telescopic rod 11. A block connected to the end of the electric telescopic rod 11 is provided between the card slot 17 and the side groove. A gap is left between the blocks, and the width of the gap is smaller than the width of the card slot 17 and the side groove.

[0039] See also Figure 2-Figure 4As shown, when the user needs to connect the restraint belt 13 with the end of the electric telescopic rod 11, the outer tube 14 can be squeezed into the slot 17. The entities at both ends of the slot 17 will squeeze the telescopic block 15. The end of the telescopic block 15 can be set to a semi-spherical shape. Under the squeezing of the entity structure, the telescopic block 15 will squeeze the second spring 16 to retract into the outer tube 14. At this time, the outer tube 14 can be clamped in the slot 17. The compressed second spring 16 resets and pushes the telescopic block 15 outward, and the telescopic block 15 is clamped in the positioning groove. , and then rotate the restraint belt 13 to drive the outer tube 14 to rotate, so that the restraint belt 13 moves from the slot 17 to the side slot. At this time, the block can block the restraint belt 13 to prevent the restraint belt 13 from returning to the slot 17, ensuring that the outer tube 14 is subjected to less downward force to prevent the outer tube 14 from escaping from the slot 17. At this time, one end of the restraint belt 13 is connected to the output shaft of the second motor 12, and the other end is connected to the end of the electric telescopic rod 11. When the electric telescopic rod 11 is shortened, it can drive both sides of the restraint belt 13 to tighten at the same time, so that the restraint belt 13 is firmly wrapped around the patient's body.

[0040] The driving assembly includes a chute tube 8 fixedly installed at the bottom of the bed board 1, a first motor 9 arranged in the chute tube 8 and a threaded rod 10 fixedly installed on the output shaft of the first motor 9, the threaded rod 10 is threadedly connected to the inner wall of the chute tube 8, the first motor 9 is fixedly connected to the electric telescopic rod 11, and the electric telescopic rod 11 is in contact with the chute tube 8.

[0041] When the user needs to adjust the position of the restraint assembly and the auxiliary restraint assembly, the first motor 9 can be started. The output shaft of the first motor 9 will drive the threaded rod 10 to rotate. The rotating threaded rod 10 will slide and displace inside the slide tube 8. The displaced threaded rod 10 drives the first motor 9 and the electric telescopic rod 11 to move, and then the moving electric telescopic rod 11 drives the restraint assembly and the auxiliary restraint assembly to move, thereby adjusting the position of the restraint assembly and the auxiliary restraint assembly.

[0042] The end of the extension rod 4 is fixedly connected to an end block 5, and the side wall of the end block 5 is arranged in an arc shape along the length direction, and a groove 6 is opened on the arc side wall of the end block 5. The adjacent end blocks 5 are tightly fitted together. When the restraint belt 13 is tightened, the restraint belt 13 will be stuck in the groove 6. As the effective length of the restraint belt 13 gradually decreases, the restraint belt 13 applies pressure to the extension rod 4 through the end block 5, forcing the extension rod 4 to compress the first spring 3 and retract into the slide groove 2. At this time, the restraint belt 13 will gradually be tied to the patient's torso, thereby improving the stability of the restraint belt 13. Moreover, the two sides of the restraint belt 13 will be blocked by the adjacent extension rods 4, which can effectively limit the position of the restraint belt 13, thereby limiting the position of the auxiliary restraint component and improving the stability of the auxiliary restraint component.

[0043] See also Figure 1 and Figure 6 As shown, the auxiliary restraint assembly includes a mounting plate 18, a clamping plate 19 fixedly mounted on the mounting plate 18, and a screw 20 rotatably connected to the mounting plate 18. The restraint belt 13 is located between the mounting plate 18 and the clamping plate 19. The end of the screw 20 is threadedly connected to a side plate 21. The side wall of the side plate 21 is hinged with an arc-shaped splint 22. The splint 22 is rotatably connected to a sliding roller 24 at one end close to the bed board 1. A connecting piece 23 is bridged between the side plate 21 and the splint 22, and the connecting piece 23 is bent upward.

[0044] As can be seen from the above, when the effective length of the restraint belt 13 is reduced and the pressure on the mounting plate 18 is increased, the mounting plate 18 applies pressure to the side plates 21 through the screw 20, and the side plates 21 then apply pressure to the splints 22. The upwardly bent connecting pieces 23 cause the splints 22 to tilt slightly inward. At this time, the splints 22 under pressure drive the sliding rollers 24 to roll on the bed board 1. As the lower ends of the splints 22 roll, the overall inclination increases, and the inclined splints 22 will be clamped on both sides of the patient's torso, increasing the restraint force on the patient. To adapt to patients of different body shapes, the user can rotate the screw 20. The screw 20 is a double-headed screw, and the spiral directions of the two ends of the double-headed screw are opposite. When the screw 20 rotates, the screw 20 will push the side plates 21 to both sides, thereby increasing the distance between the two side plates 21 and the two splints 22, so that they can be clamped on both sides of patients with wider torsos.

[0045] In order to increase the wearing comfort of the mounting plate 18, an air cushion 25 is fixedly connected to the mounting plate 18, and the lower surface of the air cushion 25 is arranged in an arc shape to facilitate the air cushion 25 to be clamped on the patient's body.
