Description

Bed for care of critically ill patients

The present invention relates to a bed for the care of seriously ill patients. More specifically, it completely levitates the contact parts of the body through mechanical levitation, ensures that the pressure position on the skin changes each time, and is equipped with a double memory foam mat on top of the mat with a built-in driving plate. It distributes pressure, enables position changes, resolves stiffness, joint movement, spinal nerve stimulation, and promotes internal movement, relieves asthenia and speeds recovery through whole-body stimulation, and promotes internal movement to strengthen digestion and appetite. The patient's sweat and moisture are removed by forced ventilation using air spray, and when necessary, ozone is sprayed into the air to sterilize, disinfect, and deodorize. After a chemical reaction, it can be automatically converted to oxygen, and 24-hour care and It is about a bed for the care of critically ill patients that allows seesaw movement, twisting movement (strong, weak), and time adjustment, and can be installed on hospital beds, regular beds, and the floor.

In general, bedsores are a disease in which the skin of a patient who has been lying in a hospital bed for a long time becomes necrotic and becomes inflamed. When a specific part of the body of a patient who has been lying in a bed for a long time is in contact with the surface of the bed for a long period of time and is continuously pressed, the pressured area may become damaged. Necrosis of the skin occurs due to poor blood circulation in the skin and poor air circulation.

To prevent bedsores, patients must be cared for all day every 1 to 2 hours. Pressure ulcers are a serious disease that can damage subcutaneous tissue, muscles, and bone tissue. Once they occur, they are difficult to treat, so prevention is of the utmost importance.

In the case of existing bedsore prevention mats or medical beds, bedsore prevention mats using heat help with blood circulation, but there is a risk of burns in unconscious patients and sweat may promote bedsores, and water and air A pressure ulcer prevention mat using has the effect of reducing pressure on the skin by distributing body weight, but since the body adheres to the surface of the mat without space, it does not allow air to pass through well, which can cause bedsores.

In addition, mats that spray air or have irregularities for good ventilation do not provide fundamental prevention because certain parts of the body that bear weight are still in contact with the mat.

There are beds that change the pressure area and improve ventilation by tilting the entire bed board to the left and right, but since the entire bed board moves, the structure is complicated and a large driving force is required, so the unit price is high and breakdowns and noise are problems.

A bed has been developed that changes the area in contact with the body by raising and lowering the uneven plate and facilitates air circulation, but the structure is complex, the production cost is high, and there are problems with frequent breakdowns, interference, and noise.

Like existing electric beds, bedsore prevention beds must have a reclining function on the back and lower body for the patient's convenience.

The biggest problem in caring for seriously ill patients is that they cannot cover their bowels and urine, so sterilization and deodorization are necessary.

Since the patient cannot move and develops bedsores, he or she must move regularly.

If you stay in bed for a long time, your muscles will weaken and you will not be able to move your body. If your body does not move, your internal organs will also deteriorate and you will not be able to swallow food.

Nutrition is important in preventing and treating bedsores.

The present invention was developed to solve the problems of the prior art. The rotation angle of the seesaw axis fixture formed on the driving plate is made greater, and the fluctuation in the height of the driving plate is further increased to adjust the time of the left and right seesaw movement and twisting movement.

As shown in Figures 1 to 5, the bed for the care of critically ill patients according to the present invention includes a frame 110 supported on the ground, and a mattress 200 mounted on the upper part of the frame 110. The bottom plate 120 of the bed is installed on the frame 110, and the mattress 200 is seated on the upper surface of the bottom plate 120.

The mattress 200 is made of a foam resin material with elasticity and elasticity, and may be equipped with a vibration motor. The mattress 200 may include a leg portion 10 and a calf portion depending on the corresponding position of the body in contact with the user while the user is lying down. It can be divided into 20), hips (30), and upper body (40).

The mounting portion 230 is formed at a position corresponding to the calf 20, hip 30, or upper body 40 of the mattress 200 by removing the internal foam member to create a space.

A driving plate 160 made of a plate is installed in the space corresponding to the calf 20, hips 30, and upper body 40 formed in this way.

The driving plate 160 is mounted inside the mounting portion 230 and may repeatedly rotate left and right and protrude toward the top of the mattress.

The driving plate 160 is made of a pad with a cushion on the upper surface and a fabric material surrounding the pad, and is installed in each space to support each hip or calf.

It includes a seesaw axis fixing unit 300, which is mounted at the lower center of the driving plate 160 so that its upper end is supported, and whose lower end is formed with a telescoping partition 320 mounted on the bottom plate 120 of the bed.

The seesaw axis fixing part 300 is formed at the lower center of the driving plate 160 so that the upper locking part 311, which connects the upper end of the telescopic partition 320, and the lower end of the expandable partition 320 are connected to the bed. It includes a lower engaging portion 312 formed on the bottom plate 120.

The telescopic bulkhead 320 is made of a rubber plate, and is formed symmetrically on both sides of the lower locking portion 312.

Therefore, after the driving plate 160 is maintained in a horizontal state, the expandable partition wall 320 is folded due to the pressure of the body weight, so that the driving plate 160 can be lowered (see FIG. 3).

Meanwhile, it is symmetrically disposed on both sides of the lower locking part 312 connected to the bottom plate 120 of the bed, and includes first and

second air pockets

410 and 420 installed to support the lower left and right sides of the driving plate 160. .

It also includes a driving unit consisting of an air hose 430 connected to the first and

second air pockets

In addition, it includes a control unit (not shown) that controls the operation of the air pump.

By an operation signal from the control unit, the first and

second air pockets

410 and 420 alternately repeat expansion and contraction, and when expanded, the driving plate 160 performs an inclined seesaw motion.

The first and

second air pockets

410 and 420 may have an air hole (not shown) formed on one side.

Therefore, in the process of injecting air, the air is discharged through the air hole and blown upward through the outer periphery of the driving plate 160, thereby blowing the patient's skin, which can help prevent bedsores.

Attach one of an air pump, air valve, PCB, ozone generator, and negative ion generator to the control unit so that ozone or negative ions are mixed in the discharged air as needed.

As an example, an ozone generator (not shown) is connected to inject ozone through an air hose.

Because ozone has sterilizing power, it can sterilize mattresses and patients, thereby maintaining clean hygiene.

In addition, the lower part is connected to the lower locking portion 312, is disposed to be inclined upward, and is connected to the lower part of the driving plate 160, and includes an elastic support plate 180 supported on the upper surfaces of the first and

second air pockets

410 and 420.

Preferably, the elastic support plate 180 is made of a rubber plate.

Therefore, when either the first air pocket 410 or the second air pocket 420 expands, the elastic support plate 180 can be pushed to form an inclined shape, and the driving plate 160 connected to it can see-saw to be inclined upward. (see Figures 4 and 5).

Accordingly, by pushing the buttocks or calves of the user lying on the driving plate 160 and lifting the body alternately left and right sequentially, it is possible to prevent bedsores in the patient and promote blood circulation to the skin and organs, thereby improving metabolism. can help you do it.

Meanwhile, the bottom plate 120 of the bed is formed to correspond to the first and

second air pockets

410 and 420, respectively, and the lower part of the driving plate 160 is supported in contact and spaced apart from the bottom plate 120, and is at an appropriate height with the mattress. It includes first and

second supports

121 and 122 respectively formed on both sides to maintain the support.

The first and

second supports

121 and 122 are made of metal or elastic material and can limit the driving plate 160 from falling below a certain height when it descends, and can also have a buffering effect to relieve impact.

The control unit includes a memory device such as a PCB board equipped with a memory chip, and a remote control (not shown) connected to the PCB board through wired or wireless communication.

The memory device controls the operation speed, operation time, restart time, etc. of the air pump.

The strength and weakness (acupressure intensity) of the vibration motor (not shown) provided in the mattress 200 is remembered in stages.

The remote control is provided with a control unit that can control the strength of the vibration motor stored in the memory device, the operation speed, operation time, restart time, etc. of the air pump.

Therefore, the user can control the speed of the seesaw movement of the driving plate 160 by arbitrarily setting the operating speed of the air pump through the remote control.

In addition, the operation time of the driving plate 160 can be set, as well as an arbitrary time can be set so that it can be restarted after stopping for a certain period of time, and the seesaw movement of the driving plate 160 can be controlled by setting.

Operations that can be implemented according to the present invention are as follows.

Mechanical levitation completely levitates the contact parts of the body, and alternating levitation is possible by allowing the pressure position of the skin to change each time.

It is easy to distribute pressure by distributing the pressure by providing a double memory foam mat on the mat with the driving plate 160 built in.

It is possible to change positions such as supine position, left position, right position, and semi-Fowler position to suit toilet handling, sheet replacement, patient undressing, and patient posture.

It relieves stiffness, joint movement, spinal nerve stimulation, and promotes internal movement, relieving asthenia and speeding recovery through whole-body stimulation. It promotes internal movement and enhances digestion and appetite.

Forced ventilation is provided using air spray to remove sweat and moisture from the patient.

When necessary, ozone can be sprayed into the air to sterilize, disinfect, and deodorize, and after a chemical reaction, it automatically converts to oxygen to generate ozone (O₃).
