[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is incorporated in an air-jet type bedsore prevention mat device used to prevent bedsores and odors of bedridden patients at home, hospitals, etc., to prevent the growth of bacteria and to prevent fragrance. The present invention relates to a plant extract vaporizer for a bedsore prevention mat that provides a stabilizing effect and a bedsore prevention mat device using the same.

[0002]

2. Description of the Related Art In recent years, bedsores, odors, and the like that occur when a bedridden state of a sick person or an elderly person for a long period of time have become a problem. A major cause of bedsores, odors, etc. is that, when the same posture is maintained for a long time, the body weight of the person and the area pressed by the mattress generate stuffiness, and an environment in which bacteria can easily propagate is created. Bedsores, odors, etc. not only cause pain to the patient himself, but also impose a burden on the caregiver, and also cause mental distress due to the odor and odor that fills the room. In addition, depending on the breeding bacteria, they may have a new disease, and if they are hospitalized, adversely affect other patients and caregivers. For this reason, bedsore prevention mats have been developed that use a method of changing the position of the patient as needed and a method of blowing air so that moisture does not accumulate on the surface of the patient's body.

[0003] As a conventional bedsore prevention mat device, there is known a device in which a plurality of rod-shaped air cells are combined and the air supplied from an air pump is controlled so that the air cells alternately expand and contract alternately. In this bedsore prevention mat apparatus, the beds are repeatedly expanded and contracted alternately to disperse the pressure applied to the body and to appropriately change the body position of the patient, thereby preventing bedsore, odor and the like. Further, as another bedsore prevention mat device, a device having a structure in which an air ejection hole is provided on the surface of the bedsore prevention mat is also known. This bedsore prevention mat device prevents bedsores, odors, etc. by preventing the air blown out from the blowout holes from constantly adjusting the humidity of the patient's skin to prevent stuffiness. On the other hand, as a method of preventing the propagation and odor of bacteria etc. in a sterile room of a hospital or the like, a method using a sterilization and deodorization gas generator which vaporizes and sends a volatile sterilization and deodorant gas into the room. Are known.
