Interventional oxygen partial pressure-temperature compound probe

Abstract

The invention discloses an interventional oxygen partial pressure-temperature compound probe which comprises a probe housing, a temperature sensing element, an oxygen partial pressure sensing elementand a temperature compensation device. The probe housing is provided with a closed head for intervening the monitored part, the middle of the closed head is provided with a blind hole for assembling the temperature sensing element, the side face of the closed head is provided with a detecting window for assembling the oxygen partial pressure sensing element, the temperature sensing element is assembled in the blind hole, and the oxygen partial pressure sensing element is assembled in the detecting window. The temperature compensation device is connected with the temperature sensing element andthe oxygen partial pressure sensing element and is used for receiving real-time temperature determined by the temperature sensing element and compensating a measurement value of the oxygen partial pressure sensing element according to the real-time temperature. Real-time and continuous monitoring of two physical signs partial pressure and temperature of the human body is achieved simultaneously by using one miniature probe, and meanwhile real-time temperature compensation of oxygen partial pressure parameters is achieved.

Description

technical field [0001] The invention belongs to the field of medical equipment, and more specifically relates to an interventional oxygen partial pressure-temperature coincident probe. Background technique [0002] Various physiological activities of the human body are inseparable from the participation of oxygen, and the oxygen metabolism index of the tissue can reflect the physiological state of the human body. Especially for intensive care patients, the reliable monitoring of oxygen metabolism indicators in the human body will help to diagnose human conditions and improve the treatment effect of patients. [0003] Take the treatment of severe neurosurgery as an example. Patients with severe neurosurgery such as stroke and craniocerebral injury often suffer from severe cerebral ischemia and hypoxic changes, which in turn lead to death or disability. Oxygen metabolism indicators measured from peripheral parts of the body cannot characterize the oxygen metabolism of brain t...
