Abstract
The utility model mainly provides a novel exhaled air carbon dioxide metering mask which is characterized in that the two sides of a hard mask main body are respectively provided with an airflow window opening, a semi-circular bag-shaped one-way airflow valve with an inward bag opening is arranged on the inner wall of the airflow window opening in one side, an outer opening of the airflow window opening in the other side is connected with a carbon dioxide flow meter, and an airflow valve which is inwards opened is arranged on the pipe wall between the outer opening and the carbon dioxide flow meter. The novel exhaled air carbon dioxide metering mask has the advantages of being widely used for situations like health care and clinical care, and being capable of achieving real-time monitoring of normal aerobic exercise limitation and clinical respiratory frequency.
Description
Technical field
This utility model relates to a kind of novel breath carbon dioxide metering face shield.
Background technology
The enforcement monitoring that the expiration carbon dioxide is measured clinical many patients with severe symptoms has extremely important meaning.The variation of the carbon dioxide content level during the patient exhales can clearly show whether this patient has dyspnea and necessary processing.Hospital often utilizes a whole set of complicated instrument to detect the variation of the carbon dioxide content level in patient's expired gas, and still a kind of less, more portative equipment of clinical needs in time judges conditions of patients.Accordingly, a kind of intention of novel breath carbon dioxide metering face shield is sent out therefrom.
The functional status of quiescent condition body can record from the amount of carbon dioxide of breathing out.The body of motion is with corresponding the increasing of the meeting of the amount of carbon dioxide in momental increase expired gas; During hyperkinesia, when in expired gas, amount of carbon dioxide exceeded the maximum oxygen uptake capacity of body, the motion of this kind situation was anaerobic exercise.Thereby, by the measurement of expired gas amount of carbon dioxide, the function present situation of body in motion as can be known.
But under some abnormal conditions, the blood oxygen carrying capability descends or histiocyte utilizes the efficiency of oxygen lower, as patients such as serious anemia, carbon monoxide poisonings, the body erythrocyte can not oxygen carrier or the cell mitochondrial of essence can not effectively utilize oxygen, thereby cause the consumption utilization of oxygen to reduce; This moment, the venous blood amount of carbon dioxide reduced, therefore carbon dioxide is breathed out, reduced.Therefore, the monitoring by the expired gas amount of carbon dioxide also can reflect body internal respiration state.
Summary of the invention
Main purpose of the present utility model is to provide a kind of novel breath carbon dioxide metering face shield.This utility model is taked following technical scheme:
A kind of novel breath carbon dioxide metering face shield, it is characterized in that, hard mask body bilateral is respectively arranged with the air-flow fenestra, a described sidewind fenestra inwall arranges three bag-shaped valves that the semilune bag mouth is inside, and opposite side air-flow fenestra collar extension connects the air-flow valve that the inside unlatching of a slice is set on carbon dioxide flow meter and the tube wall between it.
The side of described bag-shaped valve is tapered, end osculum is large.
Adopt the as above advantage of the present utility model of technical scheme to be to be widely used in the situations such as health care and clinical treatment, the Real-Time Monitoring of body metabolism rate, inside and outside breathing function in the time of can realizing different conditions.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1-mask body, 2-air-flow fenestra, the bag-shaped valve of 3-, 4-air-flow valve, 5-carbon dioxide flow meter.
The specific embodiment
In order to further illustrate this utility model, below in conjunction with accompanying drawing, further describe:
As shown in Figure 1, the said a kind of novel breath carbon dioxide metering face shield of the present embodiment, there is respectively air-flow fenestra 2 its hard mask body 1 double side wall (buccal) left and right, at three semilunes of left side air-flow fenestra 2 inwall, end osculum is large, bag mouth is inside bag-shaped valve 3, ventilation window expired gas port, right side is connected with commercially available carbon dioxide flow meter 5, on the duct wall between ventilation window and quantifier, have one inwardly open, for air-breathing lamellar valve.Wear this face shield when air-breathing, the ventilation window valve of inside opening inwardly opens wide, air-flow enters respiratory tract; During expiration, the bag mouth of the bag-shaped valve in left side opens and fills under the impact of exhaled air flow, and three full taper bags push mutually, stops breath to be breathed out from the left side ventilation window.
During use, face shield is worn over to face, freely breathes and get final product.The carbon dioxide flow meter is take the shared gas concentration lwevel of the breath of normal quiescent condition individuality as reference, estimates under different functional statuss carbon dioxide content value in breath.
This utility model cocoa is widely used in the situations such as aerobatic exercise monitoring and clinical treatment.Realize the 1. monitoring of metabolism rate: for the individuality of specific body weight, in recording unit interval, quiescent condition breath, under the prerequisite of carbon dioxide basis amount, estimate different functional statuss inside and outside on opportunity breathing function situation.2. breathing function monitoring: the breathing of human body is divided into external respiration and internal respiration.Pulmonary's motion completes the external respiration process; Blood capillary and histiocytic gas exchange are internal respiration.The function of external respiration determines to take in oxygen and discharges carbon dioxide; Internal respiration is the process that cell utilizes oxygen and discharge carbon dioxide.Because gas exchange is mainly oxygen and carbon dioxide exchange process, therefore, the amount of carbon dioxide in the monitoring breath, can draw the functional status of the inside and outside breathing of body.
Obviously, be that clearly this utility model protection domain not only is confined to this to the illustrating of embodiment, for example the shape of the unidirectional control structure of air-flow, can also be chip architecture or bag-shaped.All any changes of making under the present utility model design are all within this utility model protection domain.
