Abstract
Description
Technical Field
[0001] This invention relates to the field of nursing equipment technology, specifically to a bed position adjustment device for patients in the hematology and oncology department. Background Technology
[0002] The Department of Hematology and Oncology primarily diagnoses and treats various hematological diseases and malignant tumors, including leukemia, lymphoma, and multiple myeloma. Patients often experience symptoms such as bone marrow suppression, weakened immunity, anemia, and fatigue due to the disease itself or treatments like chemotherapy and radiotherapy, resulting in a significant decrease in their physical tolerance. Therefore, these patients usually require bed rest to reduce energy consumption, lower the risk of complications such as bleeding and infection, and facilitate disease monitoring, medication administration, and daily care by medical staff. In clinical care, patients are usually placed in a supine position, which distributes pressure evenly and reduces organ compression. Occasionally, they may be switched to a lateral position to prevent pressure sores and promote the drainage of respiratory secretions, thereby ensuring the effectiveness of nursing care and patient comfort.
[0003] However, the existing technology has the following problems: Some patients with limited mobility require assistance from medical staff when getting into bed. The patient usually lies down on the edge of the bed first, and then the medical staff manually pushes or moves the patient's body to move the patient to the middle of the bed. When the patient is lying on their side, the medical staff also need to move the patient's body on one side to turn them into a side-lying position. Moving or pushing the patient's body is physically demanding for medical staff, and it is particularly strenuous to move patients with larger body weight. For the patient, the process of moving or pushing may cause excessive pressure on a localized area of the body, resulting in discomfort. Summary of the Invention
[0004] The purpose of this invention is to provide a body position adjustment device for bedridden patients in hematology and oncology departments in order to solve the above-mentioned problems. It aims to overcome the shortcomings of existing technologies that require manually pushing or moving the patient's body when adjusting the body position of bedridden patients, which is difficult to operate and easily causes discomfort to the patient. Details are described below.

The two protrusions are respectively connected to the ends of the two crossbars away from the second nut block. The four levers are respectively connected to the rotating shafts connected to the end caps of the two support frames.
[0009] Preferably, the two levers on the support frame are set as a group, and the two protrusions are located between the two groups of levers. The protrusions contact the two levers located at the same end of the two groups of levers.
[0010] Preferably, the connecting part includes two inserts connected to the bottom surface of the substrate. A pair of wedges are slidably installed at the bottom end of the inserts. A spring is provided between the pair of wedges. Two grooves are opened on the first nut block. The two inserts are respectively embedded in the two grooves. Two slots are opened in the grooves. The pair of wedges on the inserts are respectively engaged with the two slots. The sidewall of the wedge is set as an inclined surface, and the top surface of the wedge is set as a flat surface.
[0011] Preferably, the connecting part further includes a slide block, a slide plate, and four push rods. The slide block is mounted on the mounting frame, the slide plate is vertically slidably connected to the slide block, and the four push rods are all connected to the slide plate. The positions of the four push rods correspond to the inclined surfaces of the four wedges respectively. The push rods can move upward to contact the wedges and push the wedges to retract into the insert. A curved handle is installed at the bottom of the slide plate.
[0012] Preferably, the system also includes a display mechanism comprising a spring-loaded telescopic rod, a pressure block, a slider, a connecting rod, a pointer, and a scale plate.

[0014] The beneficial effects are: 1. This bed rest position adjustment device for hematology and oncology patients features a translation mechanism. Medical staff can operate the translation mechanism by turning the first crank according to actual needs, allowing the pad to move the patient horizontally. The operation is convenient and effortless, and the patient can be moved while lying flat, avoiding excessive pressure on any part of the body that could cause discomfort. The swing mechanism allows medical staff to swing one of the support frames upwards as needed, lifting one side of the patient's body to assist in side-lying. During this process, the pad maintains a large contact area with the patient, reducing pressure on the patient's body and preventing discomfort caused by excessive pressure on any part of the body when manually lifting the patient to side-lying.
[0015] 2. The bed rest position adjustment device for patients in the hematology and oncology department has a connecting part that allows the base plate and the first nut block to be detachably connected, making it convenient for medical staff to change the pads and making the operation relatively convenient.
[0016] 3. This bed rest position adjustment device for patients in the hematology and oncology department, through the setting of the display mechanism, allows the pointer to reflect the position of the first nut block, making it easy for medical staff to determine the current position of the first nut block. Then, based on the position of the first nut block, the translation mechanism and the swing mechanism can be operated, eliminating the need for medical staff to bend over to see the position of the first nut block, further simplifying the operation and improving convenience.

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.
[0021] Example 1: Please refer to Figure 1 - Figure 7A bed positioning device for patients in hematology and oncology departments includes: a mounting frame 1, which can be mounted on a bed frame. The mounting frame 1 has bolt holes at both ends at the bottom, and is bolted to the bed frame to form a bed board; two support frames 2 are rotatably mounted on the mounting frame 1, the two support frames 2 being mirror-shaped, and a pad 3 made of flexible material is fitted onto the outside of each support frame 2, allowing it to be removed and replaced as a mattress; the mounting frame 1 is equipped with a translation mechanism 4, which drives the pad 3 to circulate between the two support frames 2 to assist the patient in adjusting their position. After the patient lies on the edge of the top surface of the pad 3, the pad 3 is driven by the translation mechanism 4 to make a conveyor belt-like cyclical movement, thereby moving the patient to the middle part of the top surface of the pad 3. The mounting frame 1 is equipped with a swing mechanism 5, which is used to drive the support frame 2 to swing upward to assist the patient in lying on their side. When the patient needs to change from lying flat to lying on their side, the swing mechanism 5 is used to drive one of the support frames 2 to swing upward. The two support frames 2 form a mechanism that can be folded. When one of the support frames 2 swings upward, it can lift the patient's body on that side to assist the patient in lying on their side.
[0022] Furthermore, the support frame 2 is divided into two frame heads and a set of rollers. The set of rollers is rotatably installed between the two frame heads. The two frame heads are rotatably connected to both ends of the mounting frame 1 through rotating shafts. The mounting frame 1 is provided with a limiting block. The bottom of the frame head abuts against the limiting block in a horizontal state. The set of rollers is distributed in a conveyor belt shape between the two frame heads. The sleeve 3 is fitted on the outside of the two sets of rollers. The rollers can rotate, thereby reducing the friction of the sleeve 3 circulating on the set of rollers. This allows the sleeve 3 to still circulate when bearing the weight of the patient's body. The sleeve 3 is provided with a zipper that can open the sleeve 3. After opening the zipper, the sleeve 3 can be disassembled and installed.
[0023] Furthermore, the translation mechanism 4 includes a first nut block 41, a base plate 42, a first lead screw 43, and a connecting part 6. The base plate 42 is installed on the bottom outer wall of the sleeve 3. The first nut block 41 is detachably connected to the base plate 42 through the connecting part 6. The first lead screw 43 is rotatably installed on the mounting bracket 1 and is threadedly connected to the first nut block 41. The first lead screw 43 is provided with a first crank handle. By rotating the first lead screw 43 through the first crank handle, the first nut block 41 is driven to move backward or forward through the threaded connection. When the first lead screw 43 rotates forward, the first nut block 41 moves backward; when the first lead screw 43 rotates in reverse, the first nut block 41 moves forward. When the first nut block 41 moves, it drives the base plate 42 to move synchronously. When the base plate 42 moves, it applies a horizontal force to the bottom of the sleeve 3, causing the sleeve 3 to perform a forward or backward cyclical movement. Previously, the first lead screw 43 was rotated forward to move the first nut block 41 and the base plate 42 into position. Then, the patient was helped to lie down from the front of the pad 3. Subsequently, the first lead screw 43 was rotated in the reverse direction to move the first nut block 41 and the base plate 42 forward to the center position. When the base plate 42 moved forward, the bottom of the pad 3 moved forward and the top moved backward, so that the patient was moved with the pad 3 to the center position of the top range of the pad 3, achieving the technical effect of moving the patient to the middle of the bed. Similarly, when the patient needs to get out of bed, the first lead screw 43 was reversed to move the top of the pad 3 forward and move the patient to the top edge of the pad 3. Medical staff can operate the translation mechanism 4 by rotating the first crank according to actual needs, so that the pad 3 can move the patient to achieve translation. The operation process is convenient and labor-saving, and the patient can be translated while lying flat, avoiding the discomfort caused by excessive local force on the patient's body.
[0024] In addition, the swing mechanism 5 includes a second nut block 51, two crossbars 52, two protrusions 53, four levers 54, and a second lead screw 55. The two crossbars 52 are horizontally slidably connected to both ends of the mounting frame 1. The second nut block 51 is connected between the two crossbars 52. The second lead screw 55 is rotatably mounted on the mounting frame 1. The second nut block 51 is threadedly connected to the second lead screw 55. A second crank is provided on the second lead screw 55. The two protrusions 53 are respectively connected to the ends of the two crossbars 52 away from the second nut block 51. The four levers 54 are respectively... Connected to the rotating shafts at both ends of the two support frames 2, the two levers 54 on the support frame 2 are set as a group, and two protrusions 53 are located between the two groups of levers 54. The protrusions 53 contact the two levers 54 located at the same end of the two groups of levers 54. When the second screw 55 is rotated by the second crank, the second screw 55 drives the second nut block 51 and the two crossbars 52 to move forward or backward through the threaded connection. When the second screw 55 rotates forward, the second nut block 51 moves forward; when the second screw 55 rotates in reverse, the second nut block 51 moves backward. When the second nut block 51 and the two crossbars 52 move forward, the two crossbars 52 drive the two protrusions 53 to move forward, causing the two protrusions 53 to push the two levers 54 on the front support frame 2 forward, causing the two levers 54 to swing forward and drive the support frame 2 to swing upward. Similarly, when the second nut block 51 and the two crossbars 52 move backward, the rear support frame 2 swings upward, and the upward swing of the support frame 2 can drive the sleeve 3 in contact with it to swing upward synchronously. For example, when the patient needs to turn from supine to forward lateral position, the medical staff reverses the second lead screw 55, and the rear support... The support frame 2 swings upward, causing the rear half of the pad 3 to lift one side of the patient's body, gradually turning the patient into a side-lying position. Through the setting of the swing mechanism 5, medical staff can operate one of the support frames 2 to swing upward according to actual needs, thereby lifting one side of the patient's body and assisting the patient to complete the side-lying action. During this process, the pad 3 always maintains a large contact area with the patient, thereby reducing the pressure on the patient's body and avoiding discomfort caused by excessive pressure on a localized area of the patient's body when manually helping the patient to lie on their side.
[0025] When the two support frames 2 swing upward, the first nut block 41 must be in the center position to avoid motion interference. When the two sides of the sleeve 3 swing upward, it will not affect the base plate 42 and the first nut block 41.
[0026] Example 2: Please refer to Figure 4 , Figure 8 , Figure 9The connecting part 6 includes two inserts 61, which are connected to the bottom surface of the base plate 42. A pair of wedges 62 are slidably mounted on the bottom end of the inserts 61, and a spring is provided between the pair of wedges 62. The first nut block 41 has two slots, and the two inserts 61 are respectively inserted into the two slots. Two slots are provided in the slots, and the pair of wedges 62 on the inserts 61 are respectively engaged with the two slots. The side walls of the wedges 62 are sloped, and the top surface of the wedges 62 is flat. Multiple gaskets 3 are provided on the base plate 42 for easy cleaning and replacement. When the base plate 42 is not connected to the first nut block 41, medical staff can manually pull it. The moving sleeve 3 performs a cyclical movement, aligning the base plate 42 with the first nut block 41, and then pressing the base plate 42 and the first nut block 41 so that the two inserts 61 are inserted into the two slots respectively. When the insert 61 is inserted into the slot, the inclined surfaces of the pair of wedges 62 above it first contact the edge of the slot, so that the wedges 62 are squeezed and retracted into the insert 61. When the wedges 62 move to the slot, the pair of wedges 62 rebound outward by the spring force, so that the wedges 62 are embedded in the slot. At this time, the flat surface of the top of the wedge 62 abuts against the inner wall of the top of the slot, forming a snap-fit structure. At this time, the connection between the base plate 42 and the first nut block 41 is completed.
[0027] It is worth noting that the connecting part 6 also includes a slide 63, a slide plate 64, and four push rods 65. The slide 63 is mounted on the mounting bracket 1, the slide plate 64 is vertically slidably connected to the slide 63, and the four push rods 65 are all connected to the slide plate 64. The positions of the four push rods 65 correspond to the inclined surfaces of the four wedges 62 respectively. When the push rods 65 move upward, they can contact the wedges 62 and push the wedges 62 to retract into the insert 61. A curved handle 66 is installed at the bottom of the slide plate 64. When it is necessary to disassemble the base plate 42 and the first nut block 41, the first lead screw 43 is used to drive the first nut block 41 to the foremost position. After the first nut block 41 moves into position, the first nut block 41 is located at... Above the slide plate 64, the four push rods 65 are aligned with the inclined surfaces of the four wedges 62. Then, the slide plate 64 is lifted upward by the curved handle 66. The slide plate 64 moves upward along the slide block 63. The four push rods 65 on the slide plate 64 contact the four wedges 62 and apply force, causing the wedges 62 to retract into the insert 61. At this time, the locking effect of the wedges 62 disappears. Medical staff can lift the base plate 42 from bottom to top to separate the base plate 42 from the first nut block 41. The connection part 6 enables the base plate 42 and the first nut block 41 to be detachably connected, which is convenient for medical staff to replace the gasket 3 and is relatively easy to operate.
[0028] Example 3: Please refer to Figure 1 , Figure 10 , Figure 11It also includes a display mechanism 7, which includes a spring-loaded telescopic rod 71, a pressure block 72, a slider 73, a connecting rod 74, a pointer 75, and a scale plate 76. The spring-loaded telescopic rod 71 is mounted on the mounting frame 1 and has multiple telescopic sections. A spring is installed inside the spring-loaded telescopic rod 71. The pressure block 72 is connected to the telescopic end of the spring-loaded telescopic rod 71 and abuts against the first nut block 41. The slider 73 is slidably mounted on the mounting frame 1. The scale plate 76 is mounted on the mounting frame 1. One end of the connecting rod 74 is hinged to the pressure block 72. The other end is hinged to the slider 73, and the pointer 75 is mounted on the slider 73. The scale plate 76 has scale lines corresponding to the position of the first nut block 41, and the pointer 75 is located on the front side of the scale plate 76. The spring inside the elastic telescopic rod 71 always applies elastic force, so that the elastic telescopic rod 71 maintains an outward extension force, so that the pressure block 72 at the end of the elastic telescopic rod 71 always abuts against the first nut block 41. When the first nut block 41 moves forward, it applies a pushing force to the pressure block 72, causing the elastic telescopic rod 71 to retract. When the first nut block 41 moves backward, the elastic telescopic rod 71 extends accordingly. The pressure block 72 maintains contact with the first nut block 41, thus allowing the pressure block 72 to move synchronously with the first nut block 41. Furthermore, the pressure block 72 and the first nut block 41 are separate structures, preventing motion interference due to their interconnection. When the pressure block 72 moves backward, it drives the slider 73 to move left along the mounting bracket 1 via the connecting rod 74; when the pressure block 72 moves forward, the slider 73 moves right. The movement of the slider 73 causes the pointer 75 to move synchronously, thus the current position of the pointer 75 reflects the position of the first nut block 41. For example, pointer 75... If the pointer is on the left, it means that the first nut block 41 is at the rear. When the first nut block 41 is in the center position, the pointer 75 is in the center. The scale line on the scale plate 76 is marked with the distance between the front and rear range of the first nut block 41. When the pointer 75 is in the center, it is exactly on the scale line in the middle of the scale plate 76. This makes it easy for medical staff to judge the current position of the first nut block 41. Then, the translation mechanism 4 and the swing mechanism 5 are operated according to the position of the first nut block 41. Medical staff do not need to bend down to see the position of the first nut block 41, which further simplifies the operation and improves convenience.
