Description

mattress {mattress}

The present invention relates to a mattress, and more particularly, to prevent bedsores and various diseases that may occur in the body of a patient who lives in bed for a long time in a hospital or the elderly or an elderly person with reduced mobility, and to prevent contamination by various excrement penetration, and It was invented to maintain a hygienic and pleasant environment at all times by preventing virus transmission and odor generation through periodic sterilization.

In general, a mattress is one of bedding, which is made to have a predetermined height by filling the inside of the outer shell with a filler. For example, a bed for a patient is not well ventilated and the surface texture is hard, so when an inpatient lies on the mattress, the patient The skin of the patient is compressed, so if it persists, it can create a factor in the occurrence of pressure sores.

In order to improve this, it is not enough to improve the cushioning and flexibility of the mattress surface by installing an air supply chamber on the bed and injecting air into the bed so that ventilation is smooth.

In addition, the control device is complicated, the price is high, and there are inconveniences that burden the patient. A device for supplying a mixture of oxygen and aroma on the bed surface has also been developed, but it is only a part of it and the efficiency is weak. There is one inconvenience.

Mattresses are composed of a mat body that performs a cushioning action and a sheet overlaid on the mat body, and special functions are required for mattresses used by the elderly or patients with reduced mobility.

For example, in the case of patients lying in bed for a long time or paralyzed patients such as paraplegia or general paralysis, blood circulation and metabolism are not smooth due to prolonged posture in the same position for a long time, resulting in bedsores in areas under pressure. .

As a measure to prevent pressure sores, a representative measure is to change the patient's lying position at regular intervals to reduce the burden on the pressure area and provide ventilation.

However, the task of periodically moving and changing the patient's posture to prevent bedsores is laborious and cumbersome, and requires a separate caregiver, which places a severe economic burden on the caregiver.

As a solution to this problem, a mat for preventing bedsores has been proposed.

That is, a plurality of air pockets formed in the body forming the basic frame and a plurality of cold and warm wind units, a first sensor unit for measuring pressure or weight, installed adjacent to the plurality of cold and warm wind units, and controlling temperature or humidity. A second sensor unit for measuring, including a piezo sensor, measuring stress applied to the piezo sensor, and converting the measured stress into an electrical signal A piezo sensor and generator formed in a matrix form on an upper portion of one surface of the body the plurality of air pockets; An air passage part interconnecting the plurality of air bags and supplying air supplied from an air pump to the plurality of air bags, the plurality of cooling and warming parts formed in a matrix form on an upper part of one surface of the body, and the first air passage part. 1 controls the air pressure in the air bag adjacent to the first sensor unit based on the pressure or weight detected through the sensor unit, and controls the air pressure in the air bag adjacent to the second sensor unit based on the temperature or humidity detected through the second sensor unit It has a structure having a control unit that controls the operation of the piezo sensor and generator and controls the operation of the cold/heat/air unit adjacent to the piezo sensor/generator based on the electrical signal converted from the piezo sensor/generator.

However, the anti-bedsore mat having such a configuration provides a constant temperature/humidity function to the patient and secures ventilation to relieve the patient's pressure sore to some extent, but has several disadvantages as follows.

That is, since it is embedded in a basic frame made of materials such as plastic, wood, and aluminum, the thickness is excessively thick, which makes handling, storage, and use inconvenient, and it is difficult and inconvenient to place it on an existing hospital bed and use it.

In addition, since the air bag is built into the basic frame, there is a disadvantage in that the effect of mitigating pressure sores is poor due to lack of ventilation.

In addition, since the height of the mattress increases when the air bag is inflated, it is not possible to provide comfort and comfort to the patient and to have a good night's sleep, which adversely affects the condition of the patient.

In particular, since a patient or hospital operator has to additionally purchase an expensive mat for preventing bedsores, the cost burden increases, which causes a problem that acts as a factor in increasing medical expenses.

The mattress according to the present invention prevents bedsores and various diseases that may occur in the body of patients who lie down for a long time in hospitals or elderly people with reduced mobility, blocks contamination by various excrement penetration, and periodically sterilizes the mattress. It was invented to prevent virus transmission and odor generation to maintain a hygienic and pleasant environment at all times.

The present invention comprises a hard cushion part 10 and a soft cushion part 20 in the form of a coil, and a cover member 30 made of woven paper for accommodating the cushion member inside, a one-way permeable sheet 40, and sterilization A sterilization means 50 is included to generate a wavelength to remove surrounding bacteria.

1 and 2 show a mattress configuration according to the present invention in an exploded perspective view and a cross-sectional view, respectively.

In the hard cushion part 10, synthetic resin yarns of a certain thickness form an irregular coil shape and are molded to a thicker thickness than the soft cushion part 20, so that not only a cushion function but also a relatively large number of air gaps are formed between the coil yarns, resulting in excellent ventilation. function will be held.

The soft cushion part 20 is a foamed resin material such as sponge or urethane foam and is adhered to one side of the hard cushion part 10 to have a cushion function while the patient is lying down.

In addition, a plurality of ventilation holes 21 are vertically and horizontally drilled in the soft cushion part 20 to allow smooth ventilation between the patient and the hard cushion part 10 .

Therefore, it is possible to prevent bedsores or various diseases that may occur in the body of patients who lie down for a long time in hospitals or the elderly with poor mobility.

Here, it is revealed that the soft cushion part 20 may be utilized while switching both sides by bonding to both sides of the hard cushion part 10, respectively.

In a state where the hard cushion part 10 and the soft cushion part 20 are joined, the mattress is completed by being received inside the cover member 30 made of woven paper.

The cover member 30 is made of soft and flexible fabric paper.

On the other hand, a unidirectional permeable sheet 40 is further installed on the outer surface of the hard cushion part 10 and/or the soft cushion part 20.

As the unidirectional permeable sheet 40, Gore-tex is selected.

As such, the unidirectional permeable sheet 40 made of Gore-Tex prevents permeation of excrement such as sweat, urine, and saliva from the outer surfaces of the hard cushion part 10 and the soft cushion part 20.

Like Gore-tex, the unidirectional permeable sheet 40 has a function of blocking moisture while transmitting air in one direction, and is a very thin layer made of Teflon-based resin that is resistant to heat or chemicals and heated to puncture countless small holes. It is composed of a membrane, and by setting the size of the hole, it has the function of not passing moisture with a large minimum particle and passing air or water vapor with a minimum particle of much smaller than moisture.

Therefore, when liquid secretion such as sweat or urine is generated from the human body, moisture is blocked from penetrating into the hard cushion part 10 and the soft cushion part 20, and the air particles are very small, so that the unidirectional It passes smoothly through the Gore-tex selected as the permeable sheet 40.

However, when the cushion members are contaminated with secretions and are damaged, smooth ventilation can be achieved while blocking.

In addition, a sterilizing means 50 is further installed inside the hard cushion part 10 to remove bacteria around the hard cushion part 10 and the soft cushion part 20 by generating a sterilizing wavelength.

That is, an LED sterilization lamp 55 that is turned on by the power of the PCB board 54 and the battery 53 is provided inside the case 51, and the LED sterilization lamp is turned on at set time intervals under the control of the PCB board 54. The sterilizing wavelength from (55) is sent out through aperture (52).

The opening of the case 51 is sealed with a cover 56.

The LED sterilization lamp 55 transmits a sterilization wavelength through the hole 52 to sterilize the area around the mattress including the cushion members.

The LED sterilization lamp 55 is harmless to the human body, has an excellent sterilization effect, and transmits light and wavelength generated from a UV-C LED with a relatively small amount of energy required to pass through the hole 52.

Therefore, it is possible to sterilize bacteria or various viruses contaminated by urination, and also to remove odors.

Here, the outside of the case 51 and the cover 56 is surrounded by a protective cushion member 60 made of a foamed resin material in which pores are repeatedly molded, and this protective cushion member 60 is a three-dimensional oval as shown in FIG. is molded into

In this way, when the case 51 and the cover 56 are covered with the protective cushion member 60, discomfort or pain will not be caused even if the patient touches them, and the sterilization wavelength can pass smoothly without being disturbed.

A passage is formed on the bottom of the hard cushion part 10 where the sterilization means 50 is installed to replace or inspect the battery 53, and then open and close through a zipper (not shown).

With the configuration of the present invention as described above, a comfortable sleeping environment is created for patients, and the mattress is sterilized and odor removed, so that virus transmission is blocked and a comfortable environment can be maintained for a long time.

Although the present invention has been described in detail only with respect to the specific embodiments described above, it is obvious to those skilled in the art that various changes and modifications are possible within the scope of the technical idea of the present invention, and it is natural that such changes and modifications fall within the scope of the appended claims. will be.
