All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The invention aims to provide the oxygen mask capable of adsorbing and detecting the carbon dioxide at the end of the breathing so as to solve the problems in the prior art, and the oxygen mask can be used for monitoring the concentration of the carbon dioxide breathed out by a patient while the patient inhales the oxygen, and can adsorb the excessive carbon dioxide breathed out, so that the manufacturing and using costs are low, and the operation method is simple and convenient.
In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description.
As shown in fig. 1-3, the invention provides an oxygen inhalation mask capable of adsorbing and detecting end-tidal carbon dioxide, which comprises a mask main body 1, wherein the mask main body 1 is made of transparent medical plastic, the inner surface (the inner surface is the surface contacted with the face of a human body) of the mask main body 1 is provided with a detection box 2 and an adsorption box 3, and the detection box 2 and the adsorption box 3 can be fixed on the mask main body 1 in an adhesive manner or can be integrally formed with the mask main body 1. The detection box 2 is filled with a detection substance, the detection substance is used for detecting the concentration of carbon dioxide, the adsorption box 3 is filled with an adsorption substance, and the adsorption substance can adsorb carbon dioxide. The mask body 1 is provided with a plurality of air outlet through holes 7, and the specific number and distribution positions of the air outlet through holes 7 can be properly adjusted according to the area and the shape of the mask body 1. The face guard main part 1 is equipped with a plurality of oxygen passageway 4, and the air inlet of oxygen passageway 4 is located the surface of face guard main part 1, and the surface of face guard main part 1 is equipped with the mouth of taking over, and the air inlet of oxygen passageway 4 is collected in the mouth of taking over department, and the air inlet of oxygen passageway 4 is connected with outside oxygen therapy pipe 8 through coupling 5 in the mouth of taking over department, and the gas outlet of oxygen passageway 4 is located the internal surface of face guard main part 1, can carry outside oxygen to the face guard main part 1 in through oxygen passageway 4.
When the end-tidal carbon dioxide concentration of the patient needs to be detected, the mask body 1 is only required to be worn on the face of the patient, the air inlet of the oxygen channel 4 is connected with the external oxygen therapy tube 8, and the detection box 2 and the adsorption box 3 are positioned between the nose and the lips of the patient, so that any uncomfortable feeling is not caused to the face of the human body. The carbon dioxide exhaled by the patient enters the detection box 2, and the concentration of the carbon dioxide can be detected by using the detection box 2. And meanwhile, carbon dioxide exhaled by the patient can be adsorbed by the adsorption material in the adsorption box 3, so that excessive carbon dioxide is prevented from being re-inhaled by the patient.
In this embodiment, the cartridge 2 and the cartridge 3 are fixed against each other, and it is understood that the cartridge 2 and the cartridge 3 are fixed side by side.
The oxygen channels 4 are provided with two air outlets of the two oxygen channels 4 respectively positioned at two sides of the detection box 2 and the adsorption box 3. The purpose of this arrangement is to improve comfort of face and nasal cavity while inhaling oxygen. In order to slow down the influence of oxygen flow on the gas in the mask main body 1, the oxygen flow can be dispersed, the impulsive force of the oxygen which is infused into the mask main body 1 is slowed down, and the discomfort of airway drying caused by oxygen inhalation and the reblowing of the end-tidal carbon dioxide into the respiratory tract caused by the larger oxygen flow are alleviated.
In this example, the test substance is litmus particles or litmus paper, and the concentration of carbon dioxide is monitored by using a litmus solution. When the detection reagent is in actual use, the detection substance needs to be moistened by adding water, so that the detection substance is kept in a moist state, and can generate chemical reaction with carbon dioxide in the mask main body 1, therefore, a liquid inlet is formed in the side wall of the detection box 2, a micro-pressure film is arranged at the liquid inlet, a liquid storage bag 9 is arranged on the outer side of the micro-pressure film, and distilled water is contained in the liquid storage bag 9.
When the detection box 2 is needed to be used, the liquid storage bag 9 is needed to be pressed by hand, so that distilled water in the liquid storage bag 9 breaks through the micro-pressure film and enters the detection box 2, and the detection substance is in a wet state, so that carbon dioxide can be detected conveniently. When the wet detection substance changes in color (namely, changes from purple to red), the carbon dioxide is detected, the concentration content can be obtained by comparing the test paper color card when the color changes from light to dark, and the color of the detection substance does not change when the concentration of the carbon dioxide is unchanged or is reduced. Whereby the concentration of carbon dioxide exhaled by the patient can be substantially detected.
In this embodiment, the material of the liquid storage bag 9 is rubber, so that the sealing performance is good, and water leakage is not easy to occur. The micro-pressure membrane is made of PVC material, and is easy to break when being subjected to the pressure of distilled water, so that the distilled water is filled.
In this embodiment, the adsorption material is nano carbon, and the specific active structure and porous network on the surface of the carbon structure are utilized to enable the adsorption material to effectively adsorb CO 2 molecules, so as to realize purification of CO 2.
In this embodiment, the detection cartridge 2 and the adsorption cartridge 3 are both rectangular cartridge structures, and have a cartridge opening on one side. The box openings of the detection box 2 and the adsorption box 3 are respectively provided with a net surface (i.e. a filter net) which is used for preventing detection substances and adsorption substances from falling out. The surface of the net surface is provided with a common sealing paste, and in the transportation process, the detection box 2 and the adsorption box 3 can be sealed through the sealing paste, so that external impurities are prevented from entering. When the sealing tape is actually used, the sealing tape can be torn off for detection.
In this embodiment, absorbent cotton is placed in the detection case 2. The water absorption device has the advantages that the water entering the detection box 2 can be absorbed in the transportation or preservation process, so that the detection box 2 is in a dry state, and the detection material is prevented from losing efficacy before use.
In this embodiment, elastic straps 6 are attached to both sides of the mask body 1 to facilitate the fixation of the mask body 1 to the patient's face.
The principles and embodiments of the present invention have been described in detail with reference to specific examples, which are provided herein to facilitate understanding of the principles and embodiments of the present invention and to provide further advantages and practical applications for those of ordinary skill in the art in light of the present teachings. In view of the foregoing, this description should not be construed as limiting the invention.
