Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a mechanism for assisting patients to get out of bed and a method for using the mechanism. Background Art

[0002] With the advent of an aging society, the number of elderly patients suffering from hemiplegia due to cerebral stroke is increasing day by day. In addition, with the rapid development of China's economy, the number of patients with lower limb injuries caused by traffic accidents is also increasing. With the increase in the number of such patients, for medical institutions, a single person accompanying method has gradually failed to meet the daily activity needs of these patients with limited mobility, and the pressure and fatigue intensity of the accompanying staff are also increasing.

[0003] If patients rely solely on medical staff to get out of bed, it will inevitably require a lot of manpower, and sometimes only one medical staff member cannot achieve the desired effect. Secondly, there are many disadvantages in the rehabilitation training of patients who can be rehabilitated by manpower alone. Moreover, hospitals with limited medical staff resources cannot take care of all patients. Therefore, many patients may be paralyzed for life due to poor rehabilitation training or uneven technical levels of medical staff, which is a huge loss for patients. Moreover, under such heavy working conditions, medical staff are also unable to guarantee that they will be consistent with every patient in the face of so many patients. Of course, if you want to get better rehabilitation training, you also need sufficient material support, which is difficult for families that are not rich to accept.

[0004] Moreover, for a person with hemiplegia or lower limb disability, long-term bed rest and less participation in outdoor activities will greatly reduce the body's resistance and make it easy to get upper respiratory tract infection. Long-term bedridden patients have more bronchial secretions and thick sputum that is difficult to cough up, which can easily cause lung infection; and lying down for a long time can easily cause muscle atrophy and joint stiffness.

[0005] Therefore, in order to reduce the pressure on hospital accompanying staff on the one hand, and for the health and economic benefits of the patients themselves on the other hand, there is an urgent need for an institution that can assist patients in using their own abilities to achieve the transfer from bed to walker. Summary of the invention

[0006] The present invention provides a mechanism for assisting patients to get out of bed in order to assist people with lower limb disabilities or elderly people with weak bodies to transfer from a bed to a walker, so that the patients can recover on their own or go out to breathe fresh air.

[0007] The present invention also provides a method for using the mechanism for assisting patients to get out of bed.

[0008] The design idea of ​​the mechanism for assisting patients to get out of bed is as follows:

[0009] 1. People with lower limb disabilities or elderly people with weak bodies have the need to get up from the bed and get out of bed and move around in their daily lives. At the same time, since the wheelchair (a wheelchair is a type of walker) is at different positions beside the bed, the patient also has the need to turn, so a rotating mechanism needs to be designed.

[0010] 2. The height of the patient's bed is different from that of the wheelchair, so a lifting device needs to be designed to facilitate the patient to get up.

[0011] 3. There is a certain distance in the process of transferring the patient from the bed to the wheelchair, so it is necessary to design a mechanism to help the patient move horizontally so that the patient can transfer by his own strength.

[0012] The technical solution adopted by the present invention to overcome the technical problems is:

[0013] A mechanism for assisting patients to get out of bed, comprising a rotating mechanism, a translation mechanism and a lifting mechanism;

[0018] Preferably, the pulley frame is rectangular, including an upper rod, a lower rod and two side rods, the upper rod is a rectangular parallelepiped and fixed on the cross bar, and the lower rod is cylindrical and connected to the two side rods through a pulley bearing.

[0019] Preferably, the support frame is provided with at least one fixing clip, which is used to clamp and fix the support frame and the bed back together, and the fixing clip is preferably a G-shaped fixing clip, which is convenient for fixing to the bed back.

[0020] Preferably, the rotating rod is provided with a handle to facilitate the patient to rotate the rotating rod to a suitable position.

[0021] Preferably, a safety rope is provided above the crossbar, one end of the safety rope is fixed to the rotating rod above the crossbar, and the other end is fixed to the free end of the crossbar. The safety rope, the crossbar and the rotating rod form a triangle, further strengthening the firmness of the bed-getting-out mechanism.

[0022] Another embodiment of the present invention further provides a method for using a mechanism for assisting a patient to get out of bed, including a method for using the mechanism for transferring from a bed to a walker and a method for using the mechanism for transferring from a bed to a walker:

[0023] The first process, i.e., the method for using the mechanism for transferring from the bed to getting out of bed, comprises the following steps:

[0024] S11, adjusting the rotating mechanism, the patient rotates the rotating rod, and the rotating rod drives the fixing device located below the cross bar to rotate, so that the fixing device rotates to a position close to the patient;

[0025] S12, adjusting the lifting mechanism, the patient pulls the hand chain hoist to drive the fixing device to move up and down, thereby adjusting the fixing device to a height equivalent to the bed surface;

DETAILED DESCRIPTION

[0042] In order to facilitate those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The following is only exemplary and does not limit the protection scope of the present invention.

[0043] Embodiment 1,

[0044] like Figure 1-3 As shown, the mechanism for assisting patients to get out of bed described in this embodiment includes a rotating mechanism, a translation mechanism and a lifting mechanism.

[0045] The rotating mechanism comprises a support frame 11 , a bearing 10 and a rotating rod 13 . The rotating rod 13 is fixed to the support frame 11 through the bearing 10 . A cross bar 2 is fixedly arranged on the upper part of the rotating rod 13 .

[0046] In this embodiment, the rotating rod 13 and the cross bar 2 are both made of 45-degree steel. This type of steel has high strength and good cutting processability, and is suitable for the mechanism described in this embodiment to withstand greater strength. The cross bar 2 and the rotating rod 13 are connected as a whole by welding.

[0047] The rotating mechanism mainly realizes rotation through an angular contact bearing. In order to obtain low friction torque, high rigidity and good rotation accuracy of the bearing, this embodiment uses a steel ball with a small outer diameter.

[0048] The shape of the support frame 11 is similar to that of the patient's bed 8 (due to Figure 1 The middle bed is not a structure that assists the patient to get out of bed, so it is indicated by a dotted line. The support frame 11 is rectangular in shape and its length is equivalent to the width of the bed. At least one fixing clip 9 is provided on the support frame 11, and the fixing clip 9 is used to clamp the support frame 11 and the bed together. In this embodiment, the fixing clip 9 is provided on the upper side and the side of the support frame 11, and the fixing clip 9 is preferably a G-shaped fixing clip, which is convenient for fixing to the bed. In addition, the rotating rod 13 is also fixed to the ground by screws (not shown in the figure). The stability of the mechanism is ensured by fixing to the bed and the ground respectively.

[0049] Furthermore, a handle 12 is provided on the rotating rod 13, and the handle is generally located in the middle and lower part of the rotating rod 13, and can also be made height-adjustable; in addition, a rubber grip cover is provided on the surface of the handle 12 to increase the friction between the hand and the handle.

[0050] The working principle of the rotating mechanism is as follows: the patient rotates the handle 12, which rotates under the action of the bearing 10, thereby driving the rotating rod 13 to rotate, thereby realizing the rotation movement of the entire mechanism.

[0051] The translation mechanism is arranged on the cross bar 2, and the translation mechanism includes a guide rail 15, a slider 14 and a pulley group. The guide rail 15 is fixed below the cross bar 2 along the length direction of the cross bar, and the slider 14 is slidably arranged on the guide rail 15. The pulley group is connected to the slider 14. By pulling the pull rope 5 of the pulley group, the slider 14 slides on the guide rail 15, thereby driving the patient arranged below the slider to translate.

[0052] In this embodiment, the pulley group includes two small pulleys 17, two middle pulleys 19 and two large pulleys 18, wherein one middle pulley and one large pulley are coaxially arranged and fixed to one end of the cross bar 2 through a pulley frame 3, another middle pulley and another large pulley are coaxially arranged and fixed to the other end of the cross bar 2 through another pulley frame 3, a connecting plate 4 is respectively arranged at the front and rear ends of the slider 14, a small pulley frame 16 is arranged on each connecting plate 4, and two small pulleys 17 are respectively arranged on a small pulley frame 16; one of the small pulleys is connected to a large pulley through a pull rope 5, and the middle pulley coaxial with the large pulley is connected to one end of the slider 14; the other small pulley is connected to another large pulley through a pull rope 5, and the middle pulley coaxial with the large pulley is connected to the other end of the slider 14. In this embodiment, the pulley frame 3 is rectangular, including an upper rod 31, a lower rod 34 and two side rods 32. The upper rod 31 is a rectangular parallelepiped and fixed on the crossbar 2; the lower rod 34 is cylindrical, which is equivalent to a pulley shaft, and the lower rod 34 is connected to the two side rods 32 through a pulley bearing 33. One of the middle pulleys 19 and one of the large pulleys 18 are coaxially arranged on the lower rod 34 of one of the pulley frames, and the other middle pulley 19 and the other large pulley 18 are coaxially arranged on the lower rod 34 of the other pulley frame.

[0053] In this embodiment, the small pulley 17, the middle pulley 19 and the large pulley 18 are all H-shaped pulleys made of stainless steel, and their diameters are 20 mm, 70 mm and 130 mm respectively.

[0054] The movement principle of the translation mechanism is: through the steering effect of the two front and rear small pulleys 17, a person pulls the pull rope 5 to drive the large pulley 18 to rotate; the rotation of the left and right large pulleys 18 is realized by the rotation of the left and right middle pulleys 19; because the left and right middle pulleys 19 are connected to the slider 14, the object under the slider 14 is driven to move left and right when the middle pulley 19 rotates.

[0055] The lifting mechanism includes a hand chain hoist 6 , which is connected to the bottom of the slider 14 , and a fixing device 11 for fixing the patient is arranged below the hand chain hoist 6 .

[0056] The hand chain hoist 6, also called the fairy hoist, chain hoist, chain hoist, jinbulu, manual hoist, is a manual lifting machinery that is simple to use and easy to carry, also known as "chain hoist" or "chain hoist". It is suitable for short-distance lifting of small equipment and goods. The lifting capacity generally does not exceed 10T, the maximum can reach 20T, and the lifting height generally does not exceed 6m. The shell material of the hand chain hoist is high-quality alloy steel, which is strong and wear-resistant and has high safety performance. When the hand chain hoist lifts the heavy object upward, the manual chain is pulled clockwise and the hand chain wheel rotates. When descending, the hand chain is pulled counterclockwise, the brake seat is separated from the brake pad, the ratchet is stationary under the action of the pawl, and the five-tooth long shaft drives the lifting sprocket to run in the opposite direction, thereby smoothly lifting and lowering the heavy object.

[0057] Hand chain hoists are of worm type and gear type. This embodiment adopts a 2K-H planetary transmission structure, which has a large transmission ratio and adopts a ratchet mechanism to prevent the lifting sprocket from reversing and avoid unsafe accidents. The specific one selected is the Yudiao brand 0.5t hand chain hoist, which is made of alloy steel, has a lifting height of 4m and a weight of 8kg.

[0058] In this embodiment, the fixing device 7 can be a safety suit or a seat with a safety belt. The safety suit is generally provided with a safety belt to ensure the safety of the patient during the transfer from the bed to the walker.

[0059] The working principle of the lifting mechanism is that the patient pulls the hand chain hoist 6 to drive the fixing device 7 to move up and down.

[0060] Furthermore, a safety rope 1 is provided above the cross bar 2, one end of the safety rope 1 is fixed to the rotating rod 13 above the cross bar, and the other end is fixed to the free end of the cross bar 2. The safety rope 1, the cross bar 2 and the rotating rod 13 form a triangle, further strengthening the firmness of the getting-out-of-bed mechanism.

[0061] The present invention uses a lifting mechanism to enable the patient to stand up or move up and down, uses a translation mechanism to enable the patient to translate himself, and uses a rotating mechanism to enable the entire mechanism to provide both front-to-back and left-to-right movement, making the scope of the entire mechanism wider and the functions of the entire mechanism more comprehensive. The three major mechanisms provide services in various directions, which not only makes the system more prominent, but also makes it easier to use in actual use due to its simplicity and clarity.

[0062] Embodiment 2,

[0064] The first process, i.e., the method for using the mechanism for transferring from the bed to getting out of the bed, comprises the following steps:

[0065] S11, adjusting the rotating mechanism, the patient rotates the handle 12 to rotate the rotating rod 13, and the rotating rod drives the fixing device 7 located below the cross bar to rotate, so that the fixing device rotates to a position close to the patient;

[0066] S12, adjusting the lifting mechanism, the patient pulls the hand chain hoist 6 to drive the fixing device 7 to move up and down, so as to adjust the fixing device to a height equivalent to the bed surface, where "equivalent" means that the bottom surface of the fixing device is slightly higher, slightly lower or equal to the bed surface;

[0067] S13, adjusting the translation mechanism, the patient pulls the pull rope 5 to translate the slider 14, thereby driving the fixing device 7 to translate onto the bed;

[0068] S14. The patient fixes his body to the fixing device 7 and takes protective measures, such as fastening a safety belt or buckling a safety buckle.

[0069] Preferably, in this embodiment, for patients who are unable to stand up directly from the bed with their arms, step S11 ′ is included before step S12 : the patient stands up by pulling the hand chain hoist 6 with his hands.

[0070] The second process, i.e., the method for transferring from the bed-moving mechanism to the walking aid, comprises the following steps:

[0071] S21, after the patient is fixed on the fixing device 7, the rotating mechanism is adjusted, the handle 12 is rotated to rotate the rotating rod 13, and the rotating rod drives the fixing device to rotate, so that the patient is rotated to a position close to the walker;

[0072] S22. Adjust the lifting mechanism. The patient pulls the hand chain hoist 6 to drive the fixing device 7 to move up and down, thereby adjusting the fixing device to a height matching the walker. The "matching height" mentioned here refers to a height at which the patient can directly transfer to the walker. For example, if the walker is a wheelchair, the matching height can be that the bottom surface of the fixing device is slightly higher, slightly lower, or equal to the sitting surface of the wheelchair.

[0073] S23. Transfer the patient to the walker and release the immobilization device.

[0074] Preferably, in this embodiment, before or after step S22, a step of adjusting the translation mechanism is further included: the patient pulls the pull rope 5 to translate the slider 14, thereby driving the patient to translate to a position facing the walker or directly above the walker.

[0075] In the description of the present invention, the directions or positional relationships indicated by terms such as "up", "down", "front", "back", "left", "right", "high", and "low" are based on the directions or positional relationships shown in the accompanying drawings, or the directions commonly used in daily life. They are only for describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0076] The above only describes the basic principles and preferred embodiments of the present invention.
