Description

Biometric meter {MEASURING INSTRUMENT FOR LIVING BODY}

The present invention relates to a biometer, and more particularly, it is designed to more accurately and safely insert a biosensor into a living body such as a human or an animal to measure the operation without additional operations such as surgery or incision for the sensor insertion. The present invention relates to a biometer that can more easily measure affected lesions.

In general, during rehabilitation of a critically ill patient or a patient in recovery after surgery or a retarded person, body temperature, blood pressure, respiration, blood, or muscle strength are measured to check the patient's condition at any time. And, in order to lead a healthier life, humans take proper nutrients while taking various nutrients and check the physical condition through periodic checkups.

Body temperature is determined by the equilibrium between heat generated in the body and heat released to the outside world.

Ingestion of various nutrients causes metabolism in vivo, of which 1/3 or 1/4 of the energy released by metabolism plays a mechanical, chemical, or electrical role, but the rest is consumed as heat. Will be maintained.

Human body temperature is generally 37 ± 1 (36 ~ 38) ℃, mercury thermometer, thermocouple thermometer, thermistor thermometer is used to measure the body temperature.

Blood pressure refers to arterial blood pressure, capillary blood pressure, and venous blood pressure, which is a pressure applied to blood vessel walls when blood flows in blood vessels, and simply refers to arterial blood pressure.

A blood pressure monitor called a sphygmomanometer is used as an instrument for measuring blood pressure. A typical blood pressure monitor includes a Riva-Rocci type blood pressure gauge using a mercury barometer or a Tycos type blood pressure gauge using an aneroid pressure gauge.

Respiration is a type of gas exchange that takes in oxygen from the outside world and releases unnecessary carbon dioxide (carbon dioxide). This respiration may be classified into tissue cell breathing, ie, internal breathing, which is performed by metabolism of carbon dioxide that is produced by releasing energy from nutrients reacting with oxygen in the cell, and exhalation of lungs through the blood giving and receiving gas. Here, the internal breathing may be a criterion for identifying the presence of biochemical abnormalities in the living body, and the external breathing is mainly an object for examining the presence of physiological abnormalities.

Physiologically, ventilation is realized as a kind of movement of air in which the rib cage surrounding the lungs changes volume by the action of the respiratory muscles such as the ribs and diaphragms, and the internal pressure of the lungs is regulated to cause a difference from the outside air pressure. In addition, there is a respiratory flow meter as a measuring system for measuring the air flow, that is, the speed and flow rate of the air flow in the airway realized when such a ventilation phenomenon occurs.

Blood is a fluid that circulates in the blood vessels of humans and animals. It carries oxygen from the lungs to tissue cells or releases carbon dioxide from tissue cells into the lungs, and transports nutrients absorbed from the digestive tract to the liver or tissue cells. As a product, unnecessary substances in the living body may be transported to the kidney to be discharged out of the body, and hormones secreted from the endocrine gland may be transported to the organ or each tissue cell, or the body heat may be evenly distributed to maintain a constant body temperature.

At this time, the blood can be tested in various ways for the purpose of diagnosis and treatment of the disease. For example, the general peripheral blood test is a test for tangible components (blood cells) in the blood to observe red blood cells, hemoglobin, hematocrit, leukocytes, and platelets. A blood biochemical test is a test for measuring chemical components in plasma or serum. It is a test for protein, carbohydrates, fats, vitamins, enzymes, and inorganic substances. This test measures the function of immunoglobulins (antibodies) and lymphocytes contained in serum.

Muscle strength is the force generated when a muscle contracts, which is the maximum tension that any muscle can produce without changing the length of the muscle, expressed in kilograms, and can be measured using a gyrometer or anusometer.

However, as described above, the conventional measuring equipment for examining various abnormalities in the living body including body temperature or blood for the purpose of healing the patient or for the purpose of periodic examinations is equipped with a special equipment room, for example, an intensive care unit or various systems. It is provided only in the measuring room, so the subject (patient) must enter the intensive care unit or measuring room and undergo a predetermined test.In addition, the specialist or nurse in charge of the medical treatment can only check the patient directly using the measuring equipment. There was a hassle.

In this case, due to the high cost of the measuring equipment and spatial constraints, all patients do not receive the benefits evenly, and there are difficulties and inconveniences of having to observe the measurement results of the patient with the specialist or nurse. There is no choice but to.

In other words, the body temperature is difficult to measure in real time because the nurse directly measures and records the patient in the middle with the thermometer, and the blood pressure is often measured at the same time as the body temperature by the nurse using a blood pressure monitor. The cumbersome, respiratory state is measured by attaching a respirator, so the place of installation is required separately.In order to measure muscle state or strength in rehabilitation patients, a muscular dynamometer is directly mounted outside the measurement site or measured for more accurate measurement. There was a major drawback of injuring the patient with another pain and incision by cutting the site and inserting the measuring device there.

Accordingly, the present invention has been made to solve the above-mentioned problems, the object of the present invention is to omit the operation or incision for the insertion of the biosensor in a living body such as humans or animals, and the biosensor It is possible to completely protect the sensor by the injection needle to reduce the pain for inserting the sensor while the post-measurement removal of the sensor to provide a biometer that can be very easily realized.
