Description

Technical Field

[0001] This invention relates to the field of nursing bed technology, and more particularly to a nursing bed for medical rehabilitation. Background Technology

[0002] Medical rehabilitation nursing beds, also known as medical beds or electric nursing beds, are specialized equipment designed for patients who are immobile, bedridden for long periods, or require rehabilitation treatment. They are far more than just a simple bed; they are a comprehensive nursing platform that integrates nursing, treatment, rehabilitation, and comfort. They can greatly reduce the workload of nursing staff and improve the quality of life and dignity of patients.

[0003] Most existing nursing beds are equipped with a toilet, allowing patients to relieve themselves in bed without having to go to the bathroom, greatly reducing the difficulty of patient care. When using existing nursing beds, patients relieve themselves through a hole in the bed, with a bedpan underneath. However, this type of nursing bed causes waste from the bedpan to splash up and contaminate the nursing bed. When the nursing bed is contaminated, it needs to be cleaned extra, increasing the workload of nursing staff. If it is not cleaned, it will not only produce odors but also breed bacteria, affecting the health of both patients and nursing staff. Summary of the Invention

The rope take-up wheel is fixedly connected to a number of transmission ropes equal to the number of mounting rods. The adjusting block of the adjusting chain is fixedly connected to a fixing component. The transmission rope is fixedly connected to the fixing component on the upper side of the adjacent adjusting chain and passes through the remaining fixing components on the adjacent adjusting chain.

[0014] More preferably, the adjusting block on the upper side of the adjusting chain is provided with a washable film.

[0015] More preferably, the second slide rail is composed of a vertical part and an arc-shaped part, and the sliding member is rotatably connected to two rollers, both of which are located inside the second slide rail.

[0016] More preferably, it also includes:

[0017] A shielding member, fixed to a plurality of the mounting rods, is used to block sewage.

[0018] More preferably, the shielding element is made of an elastic material.

[0019] More preferably, it also includes:

[0020] There are several fixing rods, all of which are fixed to the edge of the holes in the bed board. Each fixing rod is slidably connected to a sliding pad. The number of sliding pads is equal to that of the adjusting chain. A spring is provided between the sliding pad and the bed board.

[0037] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be semantically transferred to the same components having the same reference numerals or the same component names. Location descriptions selected in the specification, such as upper, lower, side, etc., also refer to the directly described and illustrated figures and are semantically transferred to the new location when the location changes.

[0038] Example 1

[0039] A type of medical rehabilitation nursing bed, such as Figures 1-6 As shown, the device includes a bed frame 1, a bed board 2 mounted on the bed frame 1, and a mattress 3 mounted on the bed board 2. Both the bed board 2 and the mattress 3 have holes. A first slide rail 4 is fixed to the lower part of the bed frame 1. A sliding frame 5 is slidably connected to the upper side of the first slide rail 4 and a first motor 6 is fixedly connected thereto. The output shaft of the first motor 6 is driven by the sliding frame 5 via a gear and rack. A first push rod 7, a second slide rail 10, and a second push rod 15 are fixedly connected to the upper side of the sliding frame 5. A sealing plate 8 is fixedly connected to the telescopic end of the first push rod 7. The sealing plate 8 is made of the same material as the bed board 2. A sealing pad 9 is installed on the upper side of the sealing plate 8, and both are located in the holes of the bed board 2 and the mattress 3, respectively. The sealing pad 9 can seal the holes of the mattress 3. To improve patient comfort; a sliding member 11 is slidably connected to the second slide rail 10, and a mounting member 12 is fixedly connected to the right side of the sliding member 11. The second slide rail 10 and the sliding member 11 can be provided in two symmetrically distributed positions. The two sliding members 11 are jointly fixedly connected to the mounting member 12, thereby enhancing the support for the mounting member 12. Six mounting rods 13 are fixedly connected to the upper side of the mounting member 12, and an adjusting chain 14 is installed on the upper side of the mounting rods 13. A transmission rod 16 is fixedly connected to the telescopic end of the second push rod 15, and a transmission block 17 that is rotatably connected to the sliding member 11 is slidably connected to the transmission rod 16. An adjusting mechanism is provided on the lower side of the mounting member 12. The adjusting mechanism is used to change the shape of all the adjusting chains 14. The second slide rail 10 consists of a vertical part and an arc-shaped part. The slider 11 is rotatably connected to two rollers 1101. Both rollers 1101 are located inside the second slide rail 10. When the slider 11 moves to the arc-shaped part of the second slide rail 10, the slider 11 tilts forward under the action of the two rollers 1101.

[0040] like Figures 1-6As shown, the adjustment mechanism includes: several elastic plates 18; an adjustment chain 14 consisting of five adjustment blocks, with adjacent adjustment blocks hinged together; the lower adjustment block fixed to the adjacent mounting rod 13; the five adjustment blocks can bend up to 90°; the elastic plates 18 are fixed between adjacent adjustment blocks; the elastic plates 18 are in a stretched state in the figure; a second motor 19 fixed to the lower side of the mounting member 12; the output shaft of the second motor 19 is fixed to a take-up wheel 20; the take-up wheel 20 is fixed to six transmission ropes 21; in the figure, the take-up wheel 20 is already wrapped with transmission ropes 21, but the transmission ropes 21 wrapped around it are not shown to make the take-up wheel 20 clearly visible; the adjustment blocks of the adjustment chain 14 are fixed to a fixing member 1401; the transmission ropes 21 are fixed to the fixing member 1401 on the upper side of the adjacent adjustment chain 14 and pass through the other fixing members 1401 on the adjacent adjustment chain 14; when the transmission ropes 21 are taut, the adjustment chain 14 will bend towards the fixing member 1401. The adjusting block on the upper side of the adjusting chain 14 is provided with a washable film 1402. The washable film 1402 is used to stick the garbage bag and prevent the garbage bag from falling off. When the surface of the washable film 1402 is contaminated and its stickiness is reduced, its stickiness can be restored by cleaning the washable film 1402.

[0041] When using this device to care for a patient, the patient lies on the device. When the patient needs to relieve themselves, the telescopic end of the second push rod 15 moves downward via the transmission rod 16 to the transmission block 17. The transmission block 17 drives the sliding member 11 to move downward. The sliding member 11 drives the roller 1101 to move to the arc-shaped part of the second slide rail 10. Under the guidance of the second slide rail 10, the two rollers 1101 tilt. The sliding member 11 drives the six adjusting chains 14 to tilt forward via the mounting member 12 and the six mounting rods 13, thereby facilitating the putting on or taking off of the garbage bag. Then, the garbage bag is put on the six adjusting chains 14, and the washing film 140 is placed on it. The garbage bag is fixed by the action of 2. Then the telescopic end of the second push rod 15 drives the six adjusting chains 14 to return to their original positions. At this time, the telescopic end of the first push rod 7 drives the sealing plate 8 to move downward. The sealing plate 8 drives the sealing pad 9 to move downward. When the sealing pad 9 is lower than the bed board 2, the telescopic end of the first push rod 7 stops moving. At this time, the output shaft of the first motor 6 rotates and drives the sliding frame 5 to move backward through the gear rack. The sliding frame 5 drives the sliding member 11 to move through the second slide rail 10. The sliding member 11 drives the mounting member 12 to move. The mounting member 12 drives the six mounting rods 13 to move. The mounting rods 13 drive the adjacent adjusting chains 14 to move.

[0042] After the mounting piece 12 is aligned with the original position of the sealing plate 8, the first motor 6 stops working. Then, the output shaft of the second motor 19 drives the take-up wheel 20 to rotate, releasing the transmission rope 21 wound on the take-up wheel 20. Under the action of the elastic plate 18, the adjusting chain 14 gradually becomes vertical. At this time, the second motor 19 is turned off, and then the second push rod 15 is started, and the transmission adjusting chain 14 moves upward. When the adjusting chain 14 reaches the specified height, the second push rod 15 is turned off and the second motor 19 is started. The output shaft of the second motor 19 winds up the transmission rope 21 through the take-up wheel 20, causing the transmission rope 21 to drive the adjusting chain 14 to bend and return to the initial state. At this time, the six adjusting chains 14 reopen the garbage bag and lay it on the upper side of the mattress 3, covering the part of the mattress 3 near the hole to prevent the mattress 3 from being contaminated. At this time, the patient can relieve himself.

[0043] After the patient finishes using the toilet, the output shaft of the second motor 19 drives the adjusting chain 14 to deform. The six adjusting chains 14, initially in an outward-expanding state, gradually straighten and then bend inward, temporarily sealing the garbage bag to mask odors and making subsequent sealing easier. This also prevents the appearance of the garbage bag from being visible, reducing the psychological burden on caregivers. After the six adjusting chains 14 are in the inward-bending state, the telescopic end of the second push rod 15 drives the adjusting chain 14 downward. The sealing pad 9 separates from the hole in the bed board 2. The output shaft of the first motor 6 then drives the adjusting chain 14 and the sealing pad 9 forward. The telescopic end of the first push rod 7 then drives the sealing pad 9 back to its original position. Simultaneously, the second push rod 15 drives the adjusting chain 14 to tilt forward, facilitating the removal of the garbage bag. Before removing the garbage bag, it is sealed. After sealing, the second motor 19 drives the six adjusting chains 14 to open, allowing the garbage bag to be removed and replaced with a new one for future use.

[0044] Example 2

[0045] Based on Example 1, such as Figures 2-5 As shown, it also includes a shield 22, fixed to several mounting rods 13, which is used to block sewage. The shield 22 is made of an elastic material, such as sponge, so that the shield 22 can change shape according to the curvature of the patient's body surface, thereby reducing the gap between the patient and the garbage bag and reducing the occurrence of sewage splashing out of the garbage bag.

[0046] Example 3

[0047] Based on Example 1, such as Figure 3As shown, it also includes: a number of fixing rods 23, twelve in the figure, all fixed to the edge of the hole in the bed board 2. Each pair of adjacent fixing rods 23 are slidably connected to a sliding pad 24. The number of sliding pads 24 is equal to that of the adjusting chain 14. The lower side of the sliding pad 24 is made of a hard material, and the rest is made of the same material as the mattress 3. A spring 2401 is provided between the sliding pad 24 and the bed board 2.

[0048] like Figure 3 As shown, the sealing plate 8 is fixed with six support rods 25. The support rods 25 and the sliding pad 24 are pressed against each other. The support rods 25 are used to support the sliding pad 24 so that the sliding pad 24 will not move downward when the patient is not relieving himself / herself, thereby reducing the difference in physical sensation between the sliding pad 24 and the mattress 3.

[0049] When the six adjustment chains 14 are open on the upper side of the mattress 3, the adjustment chains 14 press the adjacent sliding pads 24. The sliding pads 24 move downward and compress the adjacent springs 2401. At this time, the upper side of the adjustment chains 14 is flush with the upper side of the mattress 3, thereby reducing the feeling of unevenness and improving the comfort of the patient when relieving themselves. After the patient finishes relieving themselves, the adjustment chains 14 separate from the sliding pads 24. The sliding pads 24 return to their original position under the action of the adjacent springs 2401. After the sealing plate 8 is reset, the sealing plate 8 drives the support rod 25 to reset, so that the support rod 25 abuts against the sliding pads 24. This makes the deformation of the sliding pads 24 when compressed equal to that of the mattress 3, and prevents the sliding pads 24 from moving downward and causing a feeling of unevenness.

[0050] Example 4

[0051] Based on Example 1, such as Figure 3 As shown, the installation component 12 is equipped with a water storage tank 1201, which is used to store sewage. If the caregiver does not notice that the garbage bag is damaged and continues to use it, the sewage leaking from the garbage bag will enter the water storage tank 1201, thus preventing the floor from being contaminated.

[0052] like Figure 5 and Figure 7 As shown, it also includes: a drain nozzle 26, fixed to the front side of the mounting component 12, the drain nozzle 26 being connected to the water storage tank 1201, thereby facilitating the discharge of sewage from the water storage tank 1201 and facilitating the collection of sewage in the water storage tank 1201; a baffle 27, rotatably connected to the drain nozzle 26, a sealing element being provided between the baffle 27 and the drain nozzle 26, and a torsion spring 2701 being provided between the drain nozzle 26 and the baffle 27, the torsion spring 2701 being in a charged state to increase the pressure between the baffle 27 and the drain nozzle 26, improve the sealing between the two, and prevent sewage leakage.

[0053] When the garbage bag breaks, the sewage inside the garbage bag enters the water storage tank 1201. Then, when the adjusting chain 14 is in an inclined state, a new garbage bag is taken out and caught from the drain outlet 26, and the baffle 27 is opened. The baffle 27 causes the torsion spring 2701 to store force, and the sewage flows from the drain outlet 26 into the new garbage bag. Then the water storage tank 1201 can be cleaned to remove odors. After the cleaning is completed, the baffle 27 returns to its original position under the action of the torsion spring 2701.

[0054] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
