Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a wrist restraint pad which can reduce limb edema and facilitate observation in an ICU. Background Art

[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents, calibrators and materials, and other similar or related items, including the required computer software, that are used directly or indirectly on the human body. Medical devices include medical equipment and medical consumables.

[0003] The utility model with the existing authorization announcement number CN213311312U discloses a surgical arm restraint pad, including a headrest portion and arm restraint portions located on both sides of the headrest portion. The arm restraint portions are connected by a bottom pad located under the headrest portion. The headrest portion is arranged on the bottom pad so that the surgical arm restraint pad forms an integral structure.

[0004] By adopting the above technical scheme, the utility model is suitable for the patient to place the head on the headrest when the patient is in the supine position, and the arms on both sides are extended toward the top of the head and restrained on the arm restraint parts. On the one hand, by restraining the arms by extending them toward the top of the head, the arms are prevented from obstructing the surgical field during the operation. On the other hand, even if the operation time is long, the patient will not feel tired, which increases the patient's comfort during the operation. However, with the above technical scheme, when the restraint pad is used, it is not convenient for the staff to adjust the height of the restraint pad, so that the patient's elbow joint cannot be raised according to actual needs. At the same time, the restraint function of the restraint pad easily blocks the radial artery catheter on the patient's wrist, which is not convenient for the staff to observe, resulting in poor practical effect.

[0005] Therefore, those skilled in the art provide a wrist restraint pad for ICU that can reduce limb edema and facilitate observation, so as to solve the problems raised in the above background technology. Utility Model Content

[0023] See also Figure 1-4 , a wrist restraint pad for ICU that can reduce limb edema and facilitate observation, comprising a support frame 1, an adjustment mechanism 2 is arranged inside the support frame 1, and a restraint mechanism 3 is arranged above the support frame 1;

[0024] The adjustment mechanism 2 includes a constraint pad 201, the outer surface of the constraint pad 201 is slidably connected to the inner wall of the support frame 1, the outer surface of the support frame 1 is fixedly connected to two support frames 4, and the inner wall of each support frame 4 is fixedly connected to an anti-slip pad 5. By providing the support frames 4 and the anti-slip pads 5, the stability and friction of the device can be improved to avoid position displacement during use.

[0025] The outer surface of the constraint pad 201 is fixedly connected to four fixed blocks 203, the outer surface of each fixed block 203 is slidably connected to the inner wall of the support frame 1, and the inner walls of the other three fixed blocks 203 are slidably connected to the limiting columns 10, and the outer surface of each limiting column 10 is fixedly connected to the inner wall of the support frame 1. By setting the limiting columns 10, the stability of the constraint pad 201 during adjustment and lifting can be further improved, so that it can be adjusted more stably and smoothly.

[0026] The inner bottom wall of the support frame 1 is fixedly connected to a forward and reverse motor 202, the output end of the power of the forward and reverse motor 202 is fixedly connected to a first threaded rod 204, the top end of the first threaded rod 204 is fixedly connected to a second bearing 11, and the upper surface of the second bearing 11 is fixedly connected to the inner top wall of the support frame 1. By setting the second bearing 11, the stability of the first threaded rod 204 during rotation can be further increased to avoid shaking during rotation.

[0027] The outer surface of the first threaded rod 204 is threadedly connected to the inner wall of one of the fixed blocks 203, and the constraint mechanism 3 includes a movable frame 301. The inner wall of the constraint pad 201 is fixedly connected with an anti-wear pad 7, and both side surfaces of the movable frame 301 are fixedly connected with a pulling block 6. By providing the anti-wear pad 7, the anti-wear effect of the constraint pad 201 can be further improved to avoid wear and tear on the patient's arm. By providing the pulling block 6, it is convenient for the staff to pull the movable frame 301 to move through the pulling block 6, thereby quickly adjusting the position of the constraint plate 304.

[0028] The outer surface of the movable frame 301 is slidably connected to the inner wall of the support frame 1, the inner wall of the movable frame 301 is threadedly connected to the second threaded rod 302, the upper surface of the second threaded rod 302 is fixedly connected to the handle 8, and the outer surface of the handle 8 is fixedly connected to the anti-wear sleeve 9. By providing the handle 8 and the anti-wear sleeve 9, it is convenient for the staff to drive the second threaded rod 302 to rotate through the handle 8, thereby facilitating the staff to use it.

[0029] The bottom end of the second threaded rod 302 is fixedly connected to the first bearing 303, the outer ring of the first bearing 303 is fixedly connected to the constraint plate 304, the outer surface of the constraint plate 304 is slidably connected to the inner wall of the movable frame 301, and the two side surfaces of the constraint plate 304 are fixedly connected to the limiting blocks 12, and the outer surface of each limiting block 12 is slidably connected to the inner wall of the movable frame 301. By setting the limiting blocks 12, the stability of the constraint plate 304 during lifting and lowering can be further increased, so that it can be lifted and lowered more stably and smoothly.

[0030] The working principle of the utility model is as follows: when in use, the staff first transports the device to a suitable use position, and then turns on the power of the forward and reverse motor 202, so that it can be in a stable power-on state to avoid power outages during use. When the staff needs to use the device to work, the staff first places the patient's arm on the restraint pad 201, and then turns on the forward and reverse motor 202. After the forward and reverse motor 202 is turned on, it starts to generate power rotation. The rotation of the forward and reverse motor 202 can drive the first threaded rod 204 to rotate, so that under the action of the rotation of the first threaded rod 204, one of the fixed blocks 203 and the restraint pad 201 will be driven to move. When the restraint pad 201 adjusts the movement It can drive the remaining fixed blocks 203 to move, so that the height of the restraint pad 201 can be quickly adjusted, which can help the patient relieve edema. Then the staff moves the mobile frame 301 to a suitable restraint position, and then manually rotates the second threaded rod 302 through the handle 8. When the second threaded rod 302 rotates, it can drive the first bearing 303 to rotate. When the second threaded rod 302 rotates, it can move downward. At the same time, the movement of the second threaded rod 302 can drive the restraint plate 304 to move, so that the patient's wrist can be restrained. At the same time, it is also convenient to adjust the position of the restraint plate 304 to avoid affecting the staff's observation of the patient's radial artery catheterization, so that the patient's wrist can be quickly restrained.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
