Embodiment 1

[0035] Embodiment 1: A mainstream end-tidal carbon dioxide detection device, including a first housing 1 , an infrared detector, and an airway tube adapter 2 .

[0036] Such as figure 2 As shown, a slot 13 is provided on one side of the first housing 1, and the slot 13 includes two opposite surfaces, each of which is provided with a through hole. The slot 13 is "U"-shaped, and the first housing 1 is also provided with a card slot 14, the card slot 14 is arranged along the periphery of the slot 13, and the card slot 14 is provided with a groove 15, the groove 15 Located at the bottom of the "U"-shaped slot 13. The first housing 1 includes a "U"-shaped main body 11 and a "U"-shaped cover 12 disposed outside the "U"-shaped main body 11 . The length of the first housing 1 is 45-55mm, the width is 35-45mm, and the height is 18-25mm.

[0037] The infrared detector includes an emitter and a receiver, the emitter and the receiver are installed in the first housing 1, and are respe...

Embodiment 2

[0041] Embodiment 2: In order to further facilitate the detection of breathing gas and display corresponding data, this embodiment also discloses a hand-held end-tidal carbon dioxide and blood oxygen monitor 3, which replaces the traditional large-scale human breathing detection instrument to achieve handheld use. The purpose is to realize the detection of human metabolism parameters more easily and conveniently through breathing gas, including carbon dioxide detection, blood oxygen detection and so on.

[0042] Such as Figure 4 to Figure 5 As shown, in this embodiment, the mainstream end-tidal carbon dioxide detection device is connected to the hand-held end-tidal carbon dioxide oximeter 3 through a data cable.

[0043] Specifically, the handheld end-tidal carbon dioxide oximeter monitor 3 includes a second housing, a circuit board and a battery 34 . In order to facilitate the introduction of gas, the hand-held end-tidal carbon dioxide oximeter monitor 3 can also be provide...

Abstract

The invention discloses a mainstream type end expiratory carbon dioxide detecting device. The mainstream type end expiratory carbon dioxide detecting device is characterized by comprising a first housing, an infrared detector including a transmitter and a receiver and an air guiding tube adapter connected to a main expiration tube of a breathing loop. The air guiding tube adapter comprises a tubebody communicated to the breathing loop, a gas detecting portion communicated to the tube body and including a clamp-connecting terminal matched with a groove, and the clamp-connecting terminal is clamp-connected to the groove. The mainstream type end expiratory carbon dioxide detecting device is simple in structure, smaller in size, convenient to carry and use and capable of avoiding the problemof poor detection effect caused by catheter detachment in use.

Description

technical field [0001] The invention relates to the fields of health detection equipment, medical equipment, etc., and specifically relates to a mainstream type end-tidal carbon dioxide detection device, which mainly detects gas content such as carbon dioxide in breathing gas, blood oxygen blood pressure, and the like. Background technique [0002] The PetCO2 monitor is based on the principle that CO2 gas only has a strong absorption effect on infrared rays with a wavelength of 4.26 μm. When the infrared rays emitted by the sensor pass through the gas sampling chamber in the middle, the CO2 gas flowing through the chamber absorbs part of the infrared energy. After processing by the microcomputer, the PetCO2 waveform and value are displayed. The normal value of PetCO2 is 35-45mmHg. 2. PETCO2 waveform and its significance 2.1 A normal CO2 waveform can generally be divided into four phases and four segments: (1) Phase I: Inspiratory baseline, which should be at zero, is the beg...
