Description

Technical Field

[0001] The utility model relates to the technical field of rolling devices, in particular to a rolling device for a hospital bed board. Background Art

[0002] A hospital bed generally refers to a nursing bed, which is designed based on the patient's treatment needs and bedridden lifestyle, so that family members can accompany the patient. It has multiple nursing functions and operation buttons, which are convenient for medical observation and inspection and family members to operate and use. It can also be used by patients in the recovery period for rehabilitation and recuperation at home.

[0003] When using existing hospital beds, patients often raise the head of the bed 15-30 degrees or adopt a semi-sitting position while resting. Furthermore, many patients recovering from illnesses or surgeries (such as heart failure and abdominal surgery) also require a semi-sitting position. This can cause the patient's upper body to lift up in bed, causing it to slide downward due to gravity, along with the mattress, toward the footboard. This can cause the patient to slide down to the lower two-thirds of the bed, with their feet resting against the footboard. This deformed position can affect recovery and even lead to pressure ulcers on the feet. In daily life, nurses shake the bedboard flat, and two to four people work together to move the patient back to the center of the bed. On average, each patient needs to be moved two to three times daily. Each nurse repeats this operation eight to twelve times daily. For patients who are overweight or have numerous medical procedures, five to six caregivers may be required, which is extremely time-consuming and labor-intensive. Therefore, a rolling bed has been designed to address these issues and make it easier for nurses to use. Utility Model Content

[0030] A hospital bed generally refers to a nursing bed, which is designed based on the patient's treatment needs and bedridden lifestyle, so that family members can accompany the patient. It has multiple nursing functions and operation buttons, which are convenient for medical observation and inspection and family members to operate and use. It can also be used by patients in the recovery period for rehabilitation and recuperation at home.

[0031] In the prior art, patients often raise the head of the bed 15 to 30 degrees or assume a semi-sitting position when resting in bed. Furthermore, many illnesses or surgeries (such as those with heart failure or abdominal surgery) require a semi-sitting position during the recovery period. This can cause the patient's upper body to lift up in bed, causing it to slide downward due to gravity. The patient will then slide toward the foot of the bed along with the mattress, causing the patient to slide down to the lower two-thirds of the bed, with their feet resting against the footboard. This deformed position can affect recovery or even lead to pressure sores on the feet. In daily life, nurses will shake the bed flat, and two to four people will work together to move the patient back to the center of the bed. Each patient needs to be moved 2 to 3 times per day on average. Each nurse repeats this operation 8 to 12 times per day. For patients who are overweight or have too many tubes, approximately five to six caregivers will need to work together, which is very time-consuming and labor-intensive.

[0032] In order to solve the problems in the related art to a certain extent, an embodiment of the present application provides a bed board rolling device. When the patient is half leaning on the bed board, the patient will slide downward due to the center of gravity, thereby pushing the sheets to the end of the bed, causing the sheets to stack together. At the same time, the patient's feet will contact the bed board, causing pressure sores. At this time, the nurse needs to pull the bed sheet and move the patient. At this time, the nurse can rotate the handle 28 to drive the rotating rod 24 to rotate. During the rotation of the rotating rod 24, the gear 1 25 will be driven to mesh with the gear 2 27 and drive the connecting rod 1 26 to rotate, and at the same time drive the roller 1 21 to rotate. The friction between the roller 1 21 and the belt 22 drives the belt 22 to rotate, and drives the patient and the bed sheet to move upward. The roller 2 23 provides support for the central part of the belt 22, so that the bed sheet piled at the end of the bed can be stretched flat, and the patient's position can be moved so that the soles of the feet are separated from the bed board to avoid pressure sores. When the adjustment is completed, in order to prevent the rotation of the roller 1 21, the ring body 33 can be pushed to slide on the connecting rod 2 31. At the same time, the slider 34 slides inside the slide groove 32, pushing the insertion rod 36 to be inserted into the positioning hole 35, which can limit the rotation of the connecting rod 2 31 and also limit the rotation of the roller 1 21, thereby maintaining the rotation of the belt 22.

[0033] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0034] Combine Figures 1-4 , the embodiment of the present application provides a bed board rolling device, comprising: a bed frame 11 with a side panel 12 fixedly provided on the inner side thereof; a rolling assembly 2 is provided on the side panel 12, and the rolling assembly 2 comprises: two ends of a roller 1 21 are rotatably connected to the side panel 12; a belt 22 is sleeved on the outer wall of the roller 1 21; two ends of a roller 2 23 are rotatably connected to the side panel 12; one end of a rotating rod 24 passes through the side panel 12 and is rotatably connected to the side panel 12; a gear 1 25 is fixedly sleeved on the outer wall of the rotating rod 24; one end of a connecting rod 1 26 passes through the side panel 12 and is connected to the roller 1 21; a gear 27 is fixedly sleeved on the outer wall of the connecting rod 1 26 and meshes with the gear 1 25; a handle 28 is provided at one end of the rotating rod 24.

[0035] Specifically, the roller 21 and the belt 22 rotate by friction to change the patient's position.

[0036] When the patient is half-leaning on the bed board during use, the patient will slide downward due to the center of gravity, thereby pushing the bed sheet to the end of the bed, causing the bed sheets to pile up together. At the same time, the patient's feet will come into contact with the bed board, which will cause pressure sores. At this time, the nurse needs to pull the bed sheet and move the patient. At this time, the nurse can rotate the handle 28 to drive the rotating rod 24 to rotate. During the rotation of the rotating rod 24, the gear 1 25 will be meshed with the gear 2 27 and the connecting rod 1 26 will be rotated, which will also drive the roller 1 21 to rotate. The friction between the roller 1 21 and the belt 22 will drive the belt 22 to rotate, which will drive the patient and the bed sheet upward. The roller 2 23 provides support for the center part of the belt 22, which can flatten the bed sheets piled at the end of the bed and move the patient's feet to separate from the bed board to avoid pressure sores.

[0037] In some embodiments, the rolling assembly 2 further includes: a rectangular groove 241 opened at one end of the rotating rod 24 ; and a rectangular block 281 disposed at one end of the handle 28 and inserted into the rectangular groove 241 .

[0038] When in use, the rectangular block 281 at one end of the handle 28 can be inserted into the rectangular groove 241 on the rotating rod 24 to control the rotation of the rotating rod 24 when rotation is required. When rotation is not required, the handle 28 can be pulled out to avoid the design of the handle 28 affecting the nurse's walking.

[0039] In some embodiments, the rolling assembly 2 further includes a protective frame 29 disposed on an outer side wall of the side plate 12 .

[0040] The design of the protective frame 29 can prevent accidental injury when the gear 1 25 and the gear 2 27 are engaged.

[0041] In some embodiments, the rolling assembly 2 further includes: a placement block 291 disposed on the outer side wall of the side plate 12 .

[0042] During use, one end of the handle 28 can be inserted into the interior of the placement block 291 , which makes it easier to store the handle 28 .

[0043] In some embodiments, a positioning assembly 3 is provided on the outer wall of the side panel 12, and the positioning assembly 3 includes: one end of a connecting rod 2 31 passes through the side panel 12 and is connected to the roller 1 21; a slide groove 32 is opened on the outer wall of the connecting rod 2 31; a ring body 33 is sleeved on the outer wall of the connecting rod 2 31; a slider 34 is set on the inner wall of the ring body 33 and slides inside the slide groove 32; a positioning hole 35 is opened on the outer wall of the side panel 12; an insertion rod 36 is set on one side of the ring body 33, and one end is inserted into the interior of the positioning hole 35.

[0044] During use, after the adjustment is completed, in order to prevent the rotation of roller 1 21, the ring body 33 can be pushed to slide on the connecting rod 2 31, and at the same time the slider 34 slides inside the slide groove 32, pushing the insertion rod 36 to be inserted into the inside of the positioning hole 35, which can limit the rotation of the connecting rod 2 31 and the rotation of roller 1 21, thereby maintaining the rotation of the belt 22.

[0045] In some embodiments, the inner wall of the positioning hole 35 fits with the outer wall of the insertion rod 36 .

[0046] The fitting design during use can prevent shaking after the insertion rod 36 is inserted into the interior of the positioning hole 35, thereby making the fixation more stable.

[0047] In some embodiments, the positioning assembly 3 further includes: a cone 37 disposed at one end of the insertion rod 36 .

[0048] The design of the cone 37 can make it easier for the insertion rod 36 to be inserted into the positioning hole 35 during use.

[0049] In some embodiments, the positioning assembly 3 further includes: a baffle 38 disposed at one end of the second connecting rod 31 .

[0050] During use, the design of the baffle 38 can prevent the ring body 33 from being separated from the second connecting rod 31 when sliding on the second connecting rod 31.
