Description

Technical Field

[0001] This invention relates to an intensive care bed, more specifically, a mechanical suspension system that completely suspends the body contact points. The pressure points on the skin vary with each patient, and a double-layer memory foam pad is placed on the built-in drive plate to distribute pressure. This allows for changes in body position, relieving stiffness, promoting joint movement, stimulating spinal nerves, promoting visceral movement, stimulating the whole body, eliminating weakness, accelerating recovery, and improving digestion and appetite. Forced ventilation via air jets eliminates sweat and moisture from the patient. If necessary, ozone can be sprayed into the air to sterilize, disinfect, and deodorize the bed; it automatically converts into oxygen after a chemical reaction. 24-hour timed care is possible. The bed features a seesaw motion, twisting motion (strong and weak), and adjustable timing. It can be installed on hospital beds, regular hospital beds, or floors. Background Technology

[0002] Generally speaking, pressure ulcers are a disease caused by skin necrosis and inflammation in patients who are bedridden for a long time. When specific parts of the body of a patient who is bedridden for a long time are in contact with the bed surface and are continuously compressed, the blood circulation and air circulation of the skin in the compressed area are impaired, leading to skin necrosis.

[0003] To prevent bedsores, patients need to be cared for every 1-2 hours. Bedsores are a terrible disease that damages subcutaneous tissue, muscles, and bone tissue. Once they develop, they are very difficult to treat, so prevention is more important than anything else.

[0004] While warm mattresses can help improve blood circulation, they pose a risk of burns to unconscious patients, and sweat can exacerbate pressure sores. In contrast, mattresses that use water and air can distribute body weight and reduce pressure on the skin, but they lack space, and the lack of air circulation due to the body being pressed tightly against the mattress surface can lead to pressure sores.

[0005] In addition, even though air is sprayed for ventilation, some weight-bearing parts of the body are still in contact with the mat, and the irregularly shaped mat does not provide fundamental protection.

[0006] While there are beds that can tilt the entire bed board left and right, changing the pressure points and providing good ventilation, they are expensive because the entire bed board needs to be moved, the structure is complex, and a lot of driving force is required. Malfunctions and noise are also problems.

[0007] Although beds have been developed that allow raised and lowered convex and concave plates to change the contact points with the body and facilitate air circulation, they suffer from problems such as complex structure, high manufacturing cost, and frequent malfunctions, interference, and noise.

[0008] Like existing electric beds, beds designed to prevent bedsores must have a back and lower limb turning function for the patient's convenience.

[0009] The biggest problem in caring for critically ill patients is urinary and fecal incontinence, so sterilizing and deodorizing the nursing bed is necessary.

[0010] Patients who cannot move around are prone to bedsores, so they need to move around regularly.

[0011] Prolonged bed rest can lead to muscle atrophy, immobility, and even organ dysfunction, making it difficult to swallow food.

[0012] In other words, nutritional intake is very important for the prevention and treatment of bedsores. Utility Model Content

[0013] Technical challenges

[0014] This invention is proposed to solve the problems existing in the prior art. Its purpose is to provide a critical care bed that allows for a larger rotation angle of the seesaw fixing component formed on the drive plate, further increasing the height variation of the drive plate, and allowing the left and right seesaw movement and torsional movement time to be adjusted, thereby preventing bedsores and enabling movement function.

[0015] Problem Solving Methods

[0016] A critical care bed includes: a frame supported on the ground and a mattress mounted on top of the frame; a mounting portion formed in part of the mattress and in a space corresponding to the body; a drive plate installed inside the mounting portion, capable of rotating left and right repeatedly and protruding from the upper part of the mattress; a seesaw fixing component installed at the lower center of the drive plate, providing support at the top and forming the bed base, the seesaw fixing component including a telescopic partition mounted on the base; the seesaw fixing component further includes an upper suspension portion formed at the lower center of the drive plate and connecting the upper end of the telescopic partition, and a lower suspension portion formed on the base, connecting the lower end of the telescopic partition; first and second air bags symmetrically arranged on the left and right sides of the lower suspension portion connected to the bed base, the first and second air bags being configured to support the lower left and right sides of the drive plate, and a drive portion consisting of air hoses connected to the first and second air bags and an air pump connected to the air hoses and injecting air; and a control component for controlling the drive of the air pump.

[0017] The telescopic partition is made of rubber sheets.

[0018] It includes an elastic support plate, the lower part of which is connected to the lower suspension part and is arranged at an upward angle, connected to the lower part of the drive plate, and supported on the upper surface of the first and second air bags; the elastic support plate of the intensive care bed is characterized by being made of rubber sheet.

[0019] It also includes first and second supports, which correspond to the first and second air bags respectively and are formed on both sides of the base plate of the bed. The lower part of the drive plate is separated from the base plate by contacting and supporting the first and second supports, so as to maintain the same height as the mattress.

[0020] The control unit is equipped with an air pump, an air valve, a PCB, and any one of an ozone generator or a negative ion generator, so as to mix ozone or negative ions into the exhaust air as needed.

[0021] The effects of the invention

[0022] According to the present invention, the nursing bed for patients with urinary and fecal incontinence is easy to sterilize, disinfect and deodorize. Regular activity can prevent bedsores and prevent muscle atrophy and immobility caused by prolonged bed rest.

[0023] In addition, physical activity helps prevent the degeneration of internal organ function, makes it easier to swallow food, and facilitates the intake of nutrients needed to prevent and treat bedsores. Attached Figure Description

[0028] The best form of implementing an invention

[0029] The following drawings illustrate preferred embodiments in detail.

[0030] The embodiments described below will enable those skilled in the art to readily implement the invention, but this does not imply any limitation on the technical concept or category of the invention.

[0031] Furthermore, the size or shape of components shown in the drawings may be illustrated together with the chapters for clarity and convenience. In view of the structure and function of the present invention, the specially defined terms may vary according to the intention or convention of the user or operator. Please note that the definitions of these terms should be based on the entire contents of this specification.

[0032] In the attached drawings, Figure 1 This is a perspective view of the critical care bed according to the present invention. Figure 2 This is an exploded perspective view of the critical care bed according to the present invention. Figure 3 This is a cross-sectional view of the critical care bed according to the present invention. Figure 4 and Figure 5 This is a cross-sectional view of the operation of the critical care bed according to the present invention.

[0033] like Figures 1 to 5 As shown, the critical care bed according to the present invention includes a frame (110) supported on the ground and a mattress (200) mounted on top of the frame (110). A base plate (120) of the bed is mounted on the frame (110), and the mattress (200) is placed on top of the base plate (120).

[0034] The mattress (200) is made of foam resin and is made of elastic material. It can be equipped with a vibration motor and can be divided into legs (10), calves (20), buttocks (30) and upper body (40) according to the corresponding position of the user's body when lying down.

[0035] The space is created by removing the internal foam components at the positions corresponding to the lower legs (20), hips (30), or upper body (40) of the mattress (200), thereby forming the mounting portion (230).

[0036] In the spaces corresponding to the lower leg (20), hip (30) and upper body (40) formed in this way, the drive plate (160) formed by the sheet material is installed.

[0037] The drive plate (160) is installed inside the mounting part (230) and can rotate left and right repeatedly, or protrude to the top of the mattress.

[0038] The drive plate (160) is made of a pad on top and a fabric material that wraps the pad, and is installed in its own space to support the hips and calves respectively.

[0039] Installed at the lower center of the drive plate (160) to support the top and the bottom as the bed base, including a seesaw fastener forming a telescopic partition (320) mounted on the base plate (120).

[0040] The seesaw fastener includes an upper suspension part (311) formed at the lower center of the drive plate (160), an upper suspension part (311) connecting the upper end of the telescopic partition (320), and a lower suspension part (312) formed on the base plate (120), so that the lower end of the telescopic partition is connected.

[0041] The telescopic partition (320) is made of rubber sheet.

[0042] Therefore, after the drive plate (160) is kept horizontal, the telescopic partition (320) is folded by applying pressure with body weight, thereby allowing the drive plate (160) to descend (see Figure 3 ).

[0043] On the other hand, the lower suspension portion (312) symmetrically arranged on both sides of the base plate (120) connected to the bed includes the first and second air bags (410, 420) configured as the lower left and right sides of the drive plate (160).

[0044] It includes an air hose (430) connected to the first and second air bags (410, 420) respectively, and an air pump (not shown) drive unit connected to the air hose (430) and injecting air.

[0045] It also includes a control unit for controlling the air pump drive (not shown).

[0046] According to the operation signal of the control unit, the first and second air bags (410, 420) alternately expand and contract repeatedly, and when expanding, the drive plate 160 tilts to perform a seesaw motion.

[0047] The first and second air bags (410, 420) may have air holes (not shown) formed on one side.

[0048] Therefore, during the air injection process, the air is discharged through the air hole and sprayed upward through the outer edge of the drive plate (160).

[0049] Install any one of the air pump, air valve, PCB, ozone generator, or negative ion generator on the aforementioned control components to mix ozone or negative ions into the exhaust air as needed.

[0050] As an example, connect an ozone generator (not shown) to inject ozone through an air hose.

[0051] Because ozone has bactericidal properties, it can disinfect nursing beds, thereby maintaining cleanliness and hygiene.

[0052] In addition, the lower part is connected to the lower suspension part (312), is arranged at an upward angle, is connected to the lower part of the drive plate (160), and is supported by an elastic support plate (180) on the upper surface of the first and second air bags (410, 420).

[0053] The elastic support plate (180) is preferably composed of rubber sheet.

[0054] Therefore, when either the first air bag (410) or the second air bag (420) inflates, it can push the elastic support plate (180) into an inclined shape and perform a seesaw motion, causing the drive plate (160) connected to it to tilt upwards (see...). Figure 4 and Figure 5 ).

[0055] Therefore, by pushing the user's buttocks or calves while lying on the drive plate (160), the body is alternately pushed up and down on the left and right sides, which can prevent bedsores, promote blood circulation in the skin and organs, and thus help smooth metabolism.

[0056] On the other hand, the first and second supports (121, 122) are formed on the bottom plate (120) of the bed, respectively, corresponding to the first and second air bags (410, 420). The lower part of the drive plate (160) is in contact with the support and is separated from the bottom plate (120). The first and second supports (121, 122) are formed on both sides to maintain the same height as the mattress.

[0057] The first and second supports (121, 122) are made of metal or elastic material, which can limit the drive plate (160) from falling to a certain height during descent and can also have a buffering effect to reduce impact.

[0058] The control components include storage devices such as a PCB substrate with storage chips, and a remote control (not shown) connected to the PCB substrate via wired or wireless communication.

[0059] The memory device will control the speed, duration, and restart time of the aforementioned air pump.

[0060] The intensity (finger pressure) of the vibration motor (not shown) on the mattress (200) is memorized in stages.

[0061] The remote control allows for the adjustment of the vibration motor's strength, the air pump's operating speed, operating time, and restart time, all of which are stored in the memory.

[0062] Therefore, users can adjust the speed of the seesaw movement of the drive board (160) by setting the operating speed of the air pump at will using the remote control.

[0063] In addition, not only can the action time of the drive board (160) be set, but also any time can be set so that it can be restarted after a period of time, and the seesaw movement of the drive board (160) can be controlled by setting the time.

[0064] The operations that can be achieved according to the present invention are as follows.

[0065] Mechanical levitation allows the parts of the body in contact with the levitation system to be completely suspended, and the pressure points on the skin are different each time, allowing for alternating suspension.

[0066] The pad with the built-in drive plate (160) is equipped with a double layer of memory foam pad to disperse pressure and facilitate pressure distribution.

[0067] The patient can be placed in a double-lying position, left-side position, right-side position, or semi-lateral position to handle urination and defecation, change chairs, undress the patient, and change positions to suit the patient's posture.

[0068] It relieves stiffness, promotes joint movement, stimulates spinal nerves, and promotes visceral movement, thus eliminating weakness through systemic stimulation and accelerating recovery. It also promotes visceral movement and enhances digestion and appetite.

[0069] Forced ventilation using air jets removes sweat and moisture from the patient.

[0070] As needed, ozone can be sprayed into the air to sterilize, disinfect, and deodorize. After a chemical reaction, it is automatically converted into oxygen, thus having the function of generating ozone.

[0071] It can provide 24-hour care and includes seesaw exercises, twisting exercises (strong and weak), and time adjustment.

[0072] The installation can be placed on any hospital bed, regular bed, or floor.

[0073] The operation function based on an example is as follows.

[0074] 1. Operation time per session: 10 minutes, 20 minutes - optional

[0075] 2. Repeat time: 1, 2, or 3 hours - optional

[0076] 3. Exercise options: seesaw, twisting, upper body exercises - optional

[0077] 4. Pause: Maintain the top left and top right positions.

[0078] 5. Stop time: 0, 1-10 minutes - optional

[0079] 6. Drive section: Strong, Weak - Optional

[0080] 7. Air injection: (Installed with an independent pneumatic motor) Manual: Press and inject simultaneously; Automatic: Inject for 10 minutes every 30 or 60 minutes.

[0081] Although preferred embodiments have been described, various modifications and variations can be made without departing from the spirit and scope of the invention, as will be readily understood by those skilled in the art, and such modifications and variations are all within the scope of the appended claims, which is self-evident.
