Bedding prevention cushion device with ventilation function{BEDSORE PREVENTING CUSHION APPARATUS WITH BLOWING FUNCTION}

The present invention relates to an anti-bedsore cushion device having a blowing function, and more specifically, individually controls air pressure in a plurality of air pockets, and blows air upwards through a fan to provide a comfortable environment for long-term seating. The invention relates to an anti-bedsore cushion device having a blowing function.

In general, pressure ulcers occur when blood circulation is poor due to constant or repeated pressure on a certain part of the body, mainly by applying to the protrusions of the bone. Refers to a local deficiency or depression.

Pressure sore is a disease that occurs when a constant or repetitive pressure is applied to a specific part of the body, so it is mainly occurring in critically ill patients, such as paralyzed patients, whose magnetic behavior is impossible.

Patients with physical disabilities have a high risk of pressure sores because they spend most of their day lying in bed or sitting on chairs such as wheelchairs.

In addition, in the case of a pressure sore in patients with physical discomfort, there is a problem in that the recovery speed is slow due to inconvenient behavior, and the wound is more likely to worsen.

In other words, it is very important to prevent pressure sores from occurring in the elderly, because patients with discomfort are difficult to treat when pressure sores occur, and there are problems such as worsening of wounds.

As a prior patent related to the present invention, Korean Patent Utility Model No. 2016-0004011,'Anti-bedsore cushion' has been proposed.

The Korean Open Utility Model No. 2016-0004011'Absorbing Prevention Cushion' includes a plurality of air cells connected to one air passage and expanding upward by air pressure, and an air valve installed at an air inlet formed on one side of the air cell The air pressure in the air cell is controlled.

However, in the Korean Utility Model No. 2016-0004011, the ulcer prevention cushion is designed to allow air passages to pass through each other in a plurality of air cells formed vertically and horizontally. There is a disadvantage in that the air pressure is transferred to another air cell, and rather, excessive pressure is applied to a part of the body, thereby causing an adverse effect contrary to the natural effect.

In other words, the Korean Public Utility Model No. 2016-0004011,'Patient Prevention Cushion', is the most pressure applied by the buttocks when the user is seated, so the part where the buttocks are seated is compressed, and other parts, such as the thighs, are seated. There was a risk that pressure was concentrated on other parts of the thigh, etc., as the air was concentrated in the area where it was.

In addition, Korea Public Utility Model No. 2016-0004011,'Pulmonary Prevention Cushion', has a problem in that skin circulation is caused by sweat and the like due to improper air circulation when seated for a long period of time.

In addition, Korea Public Utility Model No. 2016-0004011'Absorbing Prevention Cushion' is a new product that cannot be used for the entire air cell and cannot be repaired if one air cell is damaged by wear or contact with pointed devices. Since it has to be purchased and used newly, there is a problem in that it gives an economical burden to the user, it is difficult to use for a long time, and care must be taken when handling the product.

The present invention blows air to the upper side by the operation of the fan 600 for blowing to maintain a comfortable environment when the user sits for a long time, thereby eliminating discomfort caused by sweat and heat generated in the seated body part during use, and skin disease By preventing the occurrence, the satisfaction of the elderly or patients with mobility difficulties is greatly improved.

The present invention measures pressure distribution, humidity, and temperature in real time, and provides a comfortable environment when used as measured data, thereby effectively preventing a user's pressure sores, and greatly improving satisfaction when used.

According to the present invention, since the plurality of air pockets 100 can be individually replaced, it is easy to repair and can be stably used for a long time, thereby greatly improving the economics of the product.

The present invention can clean the inside of the body casing portion 200 in which the substrate 331a for individually controlling the air pressure of the plurality of air pocket portions 100 is located therein with water, so that the inside of the body casing portion 200 It prevents the dust from being generated due to dust accumulated in the air and prevents the generation of unpleasant sensations caused by foreign substances such as dust when using, so that the environment can be kept clean during use. Improve it further.

The present invention is not limited to the above-described embodiments, but can be implemented by variously changing within a range not departing from the gist of the present invention, and it is revealed that it is included in the configuration of the present invention.
