I.Function Description

The project is the national sports committee and a joint development of sports training center.

In the process of sports training, accurately and effectively grasp the exercise intensity, to keep abreast of the degree of fatigue of athletes training for the scientific planning process is essential, the current method is commonly used in sports for athletes to carry out the process of analysis of blood samples to determine blood lactate concentration.

Transcutaneous partial pressure of oxygen without a motion detection system is the use of advanced bio-sensors closer to the athletes of the skin surface can be detected in the blood concentration of lactic acid and other major physical quantities, this method does not require blood samples, has no effect on the skin, so that with "non-invasive percutaneous" method.

People need to maintain the normal life of oxygen, oxygen is the human body and every cell of every organ of the premise of energy, the body will cause long-term hypoxia of various diseases, and clinical Oxygenating is often one of the measures used in health care, accurate real-time on the body blood oxygen monitor, you can determine the degree of hypoxia, the effect can be observed Oxygenating. "Non-invasive transcutaneous oxygen pressure measurement," through the skin non-invasive continuous measurement of blood or tissue oxygen partial pressure, and understanding of the blood or local tissue oxygen supply of blood perfusion, measured when there is no trauma on the human body, not painful.

Non-invasive transcutaneous oxygen pressure measurement

I.Function

People need to maintain the normal life of oxygen, oxygen is the human body and every cell of every organ of the premise of energy, the body will cause long-term hypoxia of various diseases, and clinical Oxygenating is often one of the measures used in health care, accurate real-time on the body blood oxygen monitor, you can determine the degree of hypoxia, the effect can be observed Oxygenating.

"Non-invasive transcutaneous oxygen pressure measurement," through the skin non-invasive continuous measurement of blood or tissue oxygen partial pressure, and understanding of the blood or local tissue oxygen supply of blood perfusion, measured when there is no trauma on the human body, not painful.

II.Principle

This equipment has been adopted advanced computer technology, electronics technology, and unique sensor technology.
Polarographic oxygen sensor is based on principle and made the size of the output signal and the oxygen partial pressure of oxygen outside the membrane is proportional to. Measurement of partial pressure of oxygen sensors will be affixed to the skin surface of patients, with the outside world cut off the gas until the oxygen through the skin to reach dynamic equilibrium, this weak signal amplification by special processing and then, finally, the screen shows that the subcutaneous tissue of partial pressure of oxygen and changes in trends. In several specific areas, such asÖâÍä, the clavicle below the lower abdomen and other parts, measured arterial oxygen partial pressure of oxygen partial pressure value and a high degree of correlation and numerical values was no significant difference.
This equipment has been adopted advanced computer technology, electronics technology, and unique sensor technology.

V. Features and Application

Noninvasive measurements can be continuous dynamic changes in oxygen partial pressure trend display, simple operation, easy to carry. Has been successfully applied in clinical respiratory monitoring, drug therapy microcirculation observation of the effects of the disease, patients with burns of the second oxygen channel clinical testing, athletes experimental hypoxic environment, animal organ oxygen partial pressure measurements in patients with cardio-cerebral vascular disease treatment partial pressure of oxygen in the blood of the clinical observations, blood pressure in patients with atypical clinical monitoring.
All involved to determine the blood oxygen, Oxygenating assessment of the effect of treatment, patients in critical care, clinical anesthesia depth assessments to determine the location of amputation surgery, to identify the extent of human aging are suitable for application areas such as
When atmospheric oxygen or liquid oxygen at the high-drip, blood pressure often is greater than 100mmHg,. Oxygen saturation equipment at this time can not reflect the changes in partial pressure of oxygen, while the apparatus is able to fully demonstrate its clinical value.

1. Blood pressure

According to physics, to a certain temperature conditions, the gas solubility in liquids, in a certain range it is proportional to the partial pressure, that is, the higher its partial pressure, was dissolved more the less the other hand, it blood oxygen content of different machines, the partial pressure of oxygen is different, high blood pressure, blood oxygen content, and low blood pressure, blood oxygen content of less, it directly reflects the blood partial pressure of oxygen in blood how much oxygen.
Clinical detection of blood oxygen partial pressure of the methods, namely, arterial blood samples for blood gas analysis, and the other is non-invasive transcutaneous measurement of blood pressure.

2. Oxygen saturation

Red blood cells in the blood plays a role of oxygen and hemoglobin to be completed by. Hemoglobin molecule in hemoglobin with four oxygen binding in the standard mode, if the hemoglobin with oxygen exposure, when reaching saturation, the per gram of hemoglobin can be combined with 1. 34mL oxygen when the oxygen saturation of hemoglobin of 100 %, while in fact most of oxygen saturation in non-saturation, normal for 95-98%. Oxygen saturation of blood oxygen saturation can be used to measure equipment.

Oxygen saturation of hemoglobin is only a reflection of the extent of combining with oxygen, can only indirectly reflect the amount of oxygen, rather than the direct representative of blood oxygen content.

3. Blood pressure and oxygen saturation relations

Between the two is not equivalent to, but the relationship between a fixed, usually referred to as "S" curve, that is, oxyhemoglobin dissociation curve. Under normal circumstances, when the partial pressure of oxygen to 100mmHg, the corresponding oxygen saturation was 98%, partial pressure of oxygen fell to 60mmHg, the oxygen saturation dropped to 90%, that is, a decrease of oxygen partial pressure 40mmHg, oxygen saturation decreased by only 8%, only when the partial pressure of oxygen less than 40mmHg, the oxygen saturation will decrease rapidly. It is only based on oxygen saturation to determine the hypoxic conditions, while the body is often neglected early hypoxia, was to conceal, easy to delayed diagnosis or failure to give timely treatment.

4. Under conditions of high oxygen partial pressure monitoring

When atmospheric oxygen or liquid oxygen at the high-drip, blood pressure often is greater than 100mmHg, blood oxygen saturation reached saturation levels, that is 100%, partial pressure of oxygen and then how changes in oxygen saturation is not reflected by the instrument , and transcutaneous oxygen pressure measurement can fully demonstrate its clinical value.
