Description

  The present invention relates to a home healthcare support system, and more particularly to a technique for alerting a patient or the like to an environment in which an oxygen supply device is used.

Conventionally, home oxygen therapy (HOT) is known as a treatment method for respiratory diseases, under the prescription and guidance of a doctor, in which a patient inhales oxygen while living daily at home. In this home oxygen therapy, an oxygen supply device capable of supplying high-concentration oxygen to a patient is installed in the patient's home and used when necessary or continuously.
Since this oxygen supply device releases high-concentration oxygen, it is necessary to be careful in handling the surrounding fire. In other words, because oxygen is a combustion-supporting substance that promotes combustion, high-concentration oxygen alone does not burn itself, but when the lighter flame or cigarette fire is brought closer, the fire suddenly increases. In addition, the cannula connected to the oxygen supply device may ignite and burn into the patient's clothes, which may cause a serious fire accident. Therefore, when using the oxygen supply device, various attentions regarding the handling of fire have been given to patients and their families, such as avoiding the fire within 2 m.

  In addition, technologies that can cope with a case where fire is used around an oxygen supply device have been proposed (for example, Patent Documents 1 and 2). Specifically, Patent Document 1 proposes a technique for issuing a warning to a patient when cigarette smoke is detected by a smoke detection sensor provided in an oxygen supply device. In Patent Document 2, when a temperature abnormality (ignition to the cannula) is detected by a temperature detection sensor provided in the vicinity of the connecting portion of the cannula, the supply of high-concentration oxygen is interrupted to prevent the fire from spreading. Technology has been proposed.
