Abstract

The utility model discloses a breathing device capable of monitoring the concentration of end-tidal carbon dioxide, which comprises an annular breathing tube and an expiration sampling tube, wherein the front side of the breathing tube is provided with a breathing head, the tail end of the breathing tube is provided with a connector connected with an oxygen supply device, and the expiration sampling tube penetrates from the outer side of the breathing tube and extends into the breathing head. The utility model can supply oxygen to the patient, collect the breath sample of the patient in real time, monitor the concentration of the carbon dioxide at the end of expiration of the patient in real time through the monitoring device, and reflect the respiration and pulmonary blood flow conditions of the patient in real time. The utility model has simple structure and small volume. In the using process, the stimulation degree to the respiratory tract of the patient is low, and the body feeling of the patient is good. The utility model has lower manufacturing cost and can be widely popularized in the market.

Description

Breathing device capable of monitoring concentration of end-expiratory carbon dioxide
Technical Field
The utility model relates to the field of medical instruments, in particular to a breathing device capable of monitoring the concentration of end-tidal carbon dioxide.
Background
End-tidal carbon dioxide monitoring, as a newer noninvasive monitoring technology, has been increasingly applied to operative anesthesia monitoring, has high sensitivity, and can monitor ventilation and reflect the circulation function and the pulmonary blood flow condition. Has become an indispensable routine monitoring means in anesthesia monitoring at present.
However, most of the existing breathing devices capable of monitoring end-tidal carbon dioxide need intubation, and are complex and large in size; brings great discomfort to the patient and brings inconvenience to the doctor during treatment.
Therefore, there is a need for a respiratory device that is compact, inexpensive to manufacture, and easy to use.
SUMMERY OF THE UTILITY MODEL
It is an object of the present invention to overcome the above problems and to provide a breathing apparatus in which the end-tidal carbon dioxide concentration can be monitored. In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a can monitor respiratory device of end carbon dioxide concentration of exhaling, includes annular respiratory tube and exhales the sampling tube, the respiratory tube front side is equipped with exhales the suction head, and the end is equipped with the connector of being connected with apparatus of oxygen supply, exhale the sampling tube and penetrate from the respiratory tube outside to extend to exhale in the suction head.
As a modification, the number of the breathing heads is two, and the breathing heads are respectively inserted into the nostrils of the patient.
As a refinement, the end of the breath sampling tube extends into one of the two exhalation heads.
As the improvement, the end of the expiration sampling tube is provided with a second connector connected with monitoring equipment.
As an improvement, the expiration sampling tube penetrates into the position of the breathing tube to be sealed.
The utility model has the advantages that:
the utility model can supply oxygen to the patient, collect the breath sample of the patient in real time, monitor the concentration of the carbon dioxide at the end of expiration of the patient in real time through the monitoring device, and reflect the respiration and pulmonary blood flow conditions of the patient in real time.
The utility model has simple structure and small volume. In the using process, the stimulation degree to the respiratory tract of the patient is low, and the body feeling of the patient is good. The utility model has lower manufacturing cost and can be widely popularized in the market.

Detailed Description
The present invention will be described in detail and specifically with reference to the following examples so as to facilitate the understanding of the present invention, but the following examples do not limit the scope of the present invention.
Example 1
The embodiment discloses a breathing device capable of monitoring end-tidal carbon dioxide concentration, which comprises a circular breathing tube 1 and an expiration sampling tube 2. The breathing tube 1 is provided with a breathing head 11 at the front side and a connector 12 at the tail end for connecting with an oxygen supply device. The expiration sampling tube 2 is threaded from the outside of the breathing tube 1 and extends into the expiration head 11. The expiration sampling tube 2 penetrates the position of the breathing tube 1 to be sealed.
The breathing heads 11 are two in number and are inserted into the nares of the patient, respectively. The end of the breath sampling tube 2 extends into one of the two breathing heads 11. The end of the expiration sampling tube 2 is provided with a second connector 21 connected with the monitoring equipment.
As shown in fig. 2, the breath sampling tube 2 penetrates into the expiratory head 11. When a patient inhales, oxygen enters the nasal cavity of the patient from a gap between the expiration sampling tube 2 and the breathing head 11, and oxygen inhalation of the patient is not influenced; when the patient exhales, the patient exhales from the exhalation sampling tube 2 and enters the monitoring equipment to monitor the carbon dioxide at the end of the patient expiration in real time.
The embodiments of the present invention have been described in detail above, but they are merely exemplary, and the present invention is not equivalent to the above described embodiments. Any equivalent modifications and substitutions to those skilled in the art are also within the scope of the present invention. Accordingly, it is intended that all equivalent alterations and modifications be included within the scope of the utility model, without departing from the spirit and scope of the utility model.
