Description

Technical Field

[0001] The utility model relates to a restraint device, in particular to a hand restraint device, belonging to the technical field of neurosurgery nursing. Background Art

[0002] Neurosurgery is a branch of surgery. It is based on surgery as the main treatment method in surgery, and uses unique neurosurgery research methods to study the human nervous system, such as the brain, spinal cord and peripheral nervous system, and its related ancillary organs, such as the skull, scalp, cerebral blood vessels and meninges, and other structural injuries, inflammation, tumors, deformities and certain genetic metabolic disorders or functional disorders. At present, neurosurgery patients usually need to recover in bed after surgery and eat through nasogastric feeding. Due to the discomfort of nasogastric feeding, medical staff usually put hand restraints on patients to fix their hands.

[0003] However, the existing hand restraint belts used in neurosurgery nursing have a single structure and poor stability during use, which makes it easy for patients to break free from the hand restraint belts. At the same time, the restraint belts are also easily damaged by patients during the struggle, which reduces the service life of the hand restraint belts. Therefore, we propose a hand restraint device to solve the above problems. Utility Model Content

[0004] In view of this, the utility model provides a hand restraint device to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0005] The technical solution of the embodiment of the utility model is implemented as follows: a hand restraint device includes a restraint mechanism, wherein the restraint mechanism includes a horizontal plate, a first screw rod, an arc block, a round rod and a first spring;

[0028] In one embodiment, two first springs 12 are fixedly connected between the cylinder 8 and the corresponding connecting block 10, and the first spring 12 is movably sleeved on the outer side of the corresponding round rod 11. Two vertical plates 13 are fixedly connected to the bottom of the horizontal plate 2, and the two vertical plates 13 are fixedly connected to the sides away from each other with a fixing rod 14, and the two vertical blocks 7 are fixedly connected to the sides away from each other with a square rod 15, and the fixing rod 14 is slidably sleeved on the outer side of the corresponding square rod 15. The same second spring 16 is fixedly connected between the fixing rod 14 and the corresponding square rod 15, and the second spring 16 is movably sleeved on the outer side of the corresponding square rod 15. The top of the first screw rod 3 is fixedly connected with a first knob 17, and the left side of the horizontal plate 2 is fixedly connected with an L-shaped block 18. The first screw rod 3 rotates to drive the horizontal rod 4 to move downward, and the horizontal rod 4 drives the two vertical rods 5 to move downward, and the vertical rod 5 squeezes the corresponding connecting rod 6 during the movement.

[0029] In one embodiment, a fixing mechanism 19 is provided below the constraint mechanism 1, and the fixing mechanism 19 includes a U-shaped block 20, a circular block 21 and a second screw 22;

[0030] A fixing mechanism 19 is provided below the L-shaped block 18, and a circular block 21 is provided on the inner side of the fixing mechanism 19. A second screw rod 22 is fixedly connected to the bottom of the circular block 21, and the bottom end of the second screw rod 22 extends to the bottom of the U-shaped block 20 and is fixedly connected to a second knob 23. The U-shaped block 20 is threadedly sleeved on the outside of the second screw rod 22, and the bottom end of the second screw rod 22 is fixedly connected to the second knob 23. The same electric telescopic rod 24 is fixedly connected between the U-shaped block 20 and the L-shaped block 18. The rotation of the second knob 23 drives the second screw rod 22 to rotate, and the rotation of the second screw rod 22 drives the circular block 21 to move upward, and the circular block 21 fixes the U-shaped block 20 to one side of the bed.

[0031] The utility model is in operation: when in use, the U-shaped block 20 is placed on one side of the bed so that the bed board is located in the U-shaped block 20, and then the second knob 23 is turned forward, the rotation of the second knob 23 drives the second screw 22 to rotate, the rotation of the second screw 22 drives the circular block 21 to move upward, and the circular block 21 fixes the U-shaped block 20 on one side of the bed. When it is necessary to adjust the height of the two arc blocks 9, the electric telescopic rod 24 is started in the reverse direction, the electric telescopic rod 24 drives the L-shaped block 18 to move downward, the L-shaped block 18 drives the cross plate 2 to move, the cross plate 2 drives the two arc blocks 9 to move, and the wrist is placed between the two arc blocks 9, and then the first knob 17 is turned forward to drive the first screw 3 to rotate, the rotation of the first screw 3 drives the cross bar 4 to move downward, the cross bar 4 drives the two vertical rods 5 to move downward, and the vertical rods 5 move the corresponding connecting rods 6 during the movement. The patient's wrist is squeezed, and under the action of the squeezing force, the connecting rod 6 moves and rotates, and the connecting rod 6 drives the corresponding vertical block 7 to move, and the vertical block 7 drives the corresponding square rod 15 to move. The vertical block 7 stretches the corresponding second spring 16 during the movement, and the vertical block 7 drives the connecting block 10 to move, and the connecting block 10 drives the corresponding arc block 9 to move. The two arc blocks 9 move in a direction close to each other and fix the patient's wrist. When the two arc blocks 9 contact the patient's wrist, the wrist generates a reaction force on the arc block 9. Under the reaction force, the arc block 9 drives the corresponding connecting block 10 to move, and the connecting block 10 drives the two round rods 11 to move. The connecting block 10 compresses the corresponding first spring 12 during the movement. The setting of the first spring 12 has a buffering effect to prevent the hard clamping force of the arc block 9 from causing wrist pain in the patient.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
