Abstract
The utility model provides a nasal oxygen cannula band ET CO2 sampling port which is a technology of non-invasively and continuously sampling expired carbon dioxide while oxygen is supplied to detect the pressure or concentration of carbon dioxide of pulmonary alveolus of a patient. The nasal oxygen cannula band ET CO2 sampling port is characterized in that a nasal plug comprises two one-way nose tips with independent cavities, wherein a catheter of one one-way nose tip without a narial tube is connected with an oxygen source for constantly supplying oxygen, and the catheter of the other one-way nose tip with a narial tube is connected to a negative pressure monitor for sampling carbon dioxide; and unions connected with the negative pressure monitor are divided into a male screwed union and a female screwed union, and is applicable to different connection unions of the negative pressure monitor. When the sampling port is used, a head-wearing catheter is hung on two sides of patient ears, the one-way nose tip with the narial tube on the nasal plug is placed in the nasal cavity of the patient, and the catheter communicated with the one-way nose tip is connected with the negative pressure monitor for constantly collecting ET CO2; and the unions connected with the negative pressure monitor is divided into a male screwed union and a female screwed union, and is applicable to various connection unions of the negative pressure monitor. The one-way nose tip without the narial tube is connected with the oxygen source for constantly supplying oxygen.
Description
Technical field:
This utility model nasal oxygen tube band ET CO
2Sample tap relates to and is used for medical patient at the oxygen pipeline of oxygen uptake process to the carbon dioxide sampling monitoring of expired gas.
Background technology:
Oxygen inhalation therapy is medically a kind of important treatment means, and the patient of various disease is different to the demand of nasal oxygen tube.Oxygen inhalation therapy plays a very important role for the thorough recovery of disease.
ET CO
2Monitoring is the expired gas carbon dioxide monitoring, is a kind of non-invasive method that continues to monitor alveolar pressure carbon dioxide or concentration.Clinical medicine is thought Pet CO
2With partial pressure of carbon dioxide in arterial blood (Pa CO
2) good dependency is arranged, so be widely used in the monitoring of all kinds of ventilatory functions.Because Pet CO
2Monitoring can be indicated the air-flow that comes from alveolar rapidly, thus be the fast reaction index of general anesthesia or other tracheal intubation accuracys, while Pet CO
2Also can be used as the monitoring and the evaluation index of cardiac function and circulatory function.
This utility model nasal oxygen tube band ETCO
2Sample tap when giving patient's oxygen supply noinvasive constantly to patient's expired gas carbon dioxide sampling monitoring.
Summary of the invention:
This utility model nasal oxygen tube band ET CO
2Sample tap be a kind of in oxygen supply the technology to the non-invasive lasting sampling of expired gas carbon dioxide, with the monitoring patient alveolar pressure carbon dioxide or concentration.
This utility model nasal oxygen tube band ET CO
2The technical scheme that sample tap adopts is that the nose plug forms one by the single-pass nose of two individual cavity
Individual the connection with source of oxygen with the conduit of the single-pass nose of nasal tubes is used for continuing oxygen supply, and another conduit that has the single-pass nose of nasal tubes is received the negative pressure monitor and carried out the carbon dioxide sampling.The joint that is connected with the negative pressure monitor divides public screwed union and female screwed union, applicable to the different jointing of negative pressure monitor.

The specific embodiment:
Earlier the headgear conduit is hung over patient's ear both sides during use, then the single-pass nose of the band nasal tubes on the nose plug is placed in patient's nasal cavity, the conduit that communicates is with it received the negative pressure monitor, is used for continuous collecting ET CO
2The joint that is connected with the negative pressure monitor divides public screwed union and female screwed union, applicable to the different jointing of negative pressure monitor.With not being connected with source of oxygen, be used for continuing oxygen supply with the single-pass nose of nasal tubes.
Claims (2)
1. nasal oxygen tube band ET CO
2Sample tap: its nose plug characteristic is to be that conduit by the single-pass nose of two individual cavity is connected with source of oxygen to be used for continuing oxygen supply that another conduit that has the single-pass nose of nasal tubes is received the negative pressure monitor and carried out the carbon dioxide sampling.
2. nasal oxygen tube band ET CO according to claim 1
2Sample tap: the joint that is connected with the negative pressure monitor divides public screwed union and female screwed union, applicable to the different jointing of negative pressure monitor.
