Wear-type hypoglycemia symptom warning device

The present invention relates to a warning device, especially a wearable hypoglycemia symptom warning device.

With the advancement of medicine and the development of the biomedical industry, many tests that were previously only possible in hospitals have been tested, traced and controlled by means of home medical care. For example, miniaturized blood glucose meters have received a lot of attention in recent years. They are mainly used to estimate the amount of glucose in the blood, so that users (such as diabetic patients) can easily use it in daily life to know the current situation. Physiological condition.

For example, in the Republic of China Patent Publication No. 201350085, a blood glucose meter is disclosed which reads a blood glucose level table in which a measured blood sugar level is recorded when the power is turned on and/or when the power is turned off, and calculates the current to the prescribed value. The moving average value of the blood sugar level measured in the past period is evaluated by the five-stage evaluation, and as a result, one of the five face illustrations is displayed on the display unit. This allows the patient to clearly determine the management status of his or her blood glucose level.

However, for diabetic patients, the most common complication is hypoglycemia. Most people with diabetes take hypoglycemic drugs or insulin, so there may be symptoms of hypoglycemia. In severe cases, patients It may be a loss of consciousness or even a coma. In order to maintain normal blood glucose concentration, it is a burden for the blood glucose meter to be taken by the needle at least three times a day for the blood glucose meter. If the needle is added for the possible hypoglycemia symptoms, the patient's pain and infection are increased invisibly. The opportunity for foreign diseases, therefore, for the monitoring of hypoglycemia symptoms, there are still good strategies to improve.

The main object of the present invention is to solve the conventional blood glucose meter, which is to obtain blood by pinching a needle through a patient's finger, and then to measure the blood sugar concentration, but there is no mechanism for preventing hypoglycemia without needle sticking.

To achieve the above object, the present invention provides a wearable hypoglycemia symptom warning device comprising a housing, a holding member, a detecting module and a warning device. The housing has a recess, the holder is coupled to the housing, and the housing is fixed to a user, and the recess forms a chamber between the skin facing the user and the skin; The detecting module is disposed in the housing, and includes a humidity sensor for detecting a humidity in the chamber, a heartbeat sensor for measuring a number of heartbeats of the user, and measuring the use An integrated temperature sensor and a processing unit respectively electrically connected to the humidity sensor, the heartbeat sensor and the temperature sensor, the processing unit determining the humidity, the number of heartbeats, and the body temperature A warning signal is sent after the threshold is met; and the warning device is disposed in the housing and electrically connected to the processing unit, and the warning device displays the warning signal to display a degree of hypoglycemia symptoms of the user. reading.

In this way, the present invention determines the degree of reading of the hypoglycemia symptom in a non-invasive manner by detecting the humidity associated with the skin, the number of heartbeats, and the body temperature, which not only allows the user to monitor at any time. The physical condition of the body, in response to the hypoglycemia symptoms in advance, also allows the user to do not need extra needle blood glucose, to avoid additional pain and the risk of infection.
