Sleep respiration monitoring device capable of monitoring end-tidal carbon dioxide

Abstract

A sleep respiration monitoring device capable of monitoring end-tidal carbon dioxide comprises a wristwatch type casing and watchbands connected with the wristwatch type casing, wherein the wristwatch type casing comprises a front casing body and a rear casing body which are connected with each other, a circuit board is arranged between the front casing body and the rear casing body, a display screen is arranged on the front casing body, a battery for supplying electric power to the circuit board is arranged on the rear casing body, and a nasal airflow interface, a gas collecting terminal data interface and a blood-oxygen probe interface are formed in one side surface of the connected surface of the front casing body and the rear casing body. According to the sleep respiration monitoring device capable of monitoring end-tidal carbon dioxide, end-tidal carbon dioxide is collected by adopting a by-pass flow mode instead of a traditional air pump, so that a product is wholly small and exquisite in structure and is portable, the designed main body structure is the wristwatch type casing, the device can be worn on the wrist through the watchbands, measurement results of end-tidal carbon dioxide, respiration, the degree of blood-oxygen saturation and the pulse rate are displayed on the display screen through a microprocessor module, and accordingly, the condition of a patient can be observed in real time.

Description

technical field [0001] The invention relates to the field of vital sign detection, in particular to a sleep respiration monitoring device capable of monitoring end-tidal carbon dioxide. Background technique [0002] The end-tidal carbon dioxide concentration is another vital sign of the human body besides blood pressure, ECG, body temperature and respiration. The end-tidal carbon dioxide concentration waveform can well reflect the physiological state of the human body in the process of metabolism, respiration, circulation and anesthesia. Therefore, the detection of end-tidal carbon dioxide concentration is an important monitoring procedure clinically. At present, there are two ways to monitor end-tidal carbon dioxide. One is a ventilator with an end-tidal carbon dioxide detection module. Or anesthesia machine, however, only patients who are critically ill or need anesthesia use a ventilator or anesthesia machine. Or the anesthesia machine is expensive to use for patients wh...

[0002] The end-tidal carbon dioxide concentration is another vital sign of the human body in addition to blood pressure, ECG, body temperature and respiration. The end-tidal carbon dioxide concentration waveform can well reflect the physiological state of the human body in the process of metabolism, respiration, circulation and anesthesia. Therefore, the detection of end-tidal carbon dioxide concentration is clinically regarded as an important monitoring procedure. At present, there are two ways to monitor end-tidal carbon dioxide. One is a ventilator with an end-tidal carbon dioxide detection module. Or anesthesia machine, however, only patients who are critically ill or need anesthesia use ventilators or anesthesia machines, ventilators and anesthesia machines have complex functions and large structural volumes, and ordinary respiratory patients do not need ventilators or anesthesia machines, so ventilators Or the anesthesia machine is expensive to use for patients who only check end-tidal carbon dioxide, and it is inconvenient. Another way to detect end-tidal carbon dioxide is an ordinary multi-parameter monitor, that is, a desktop monitor, a collection of monitors Adult parameters such as blood pressure, blood oxygen, pulse rate, respiration, ECG, body temperature, etc. are generally used for bedside monitoring. Suitable for deficiencies such as patient transfer
