The application provides a multifunctional gas collecting mask, wherein a slot for installing a resistance net converter is arranged on a port, far away from the face, of an air flow collector, and different functions of air flow detection are realized by aligning resistance nets with different resistances on the resistance net converter to the port of the air flow collector, so that the multifunctional gas collecting mask is integrated, a patient does not need to switch the gas collecting mask when simultaneously carrying out various air flow detection, the detection flow is simplified, and the medical experience is improved.
As shown in fig. 1 and 2, the multifunctional gas collecting mask provided by the application comprises a gas flow collector 20, wherein the gas flow collector 20 is a cavity with two open ends, one end of the gas flow collector surrounds the mouth and nose parts of the face of a patient, and the other end of the gas flow collector is used as a gas flow inlet and outlet. As shown in fig. 2, the shape of the portion of the airflow collector 20 close to the face is matched with the face, and the portion far from the face is tubular, so as to smooth and stabilize the airflow, and facilitate the airflow detection.
The air flow collector 20 is provided with a slot at a port far away from the face (i.e. the end of the tubular part in fig. 2), a resistance net converter 30 is arranged in the slot, and a first pipeline 90 and a second pipeline 100 connected with the oral-nasal air flow detector are respectively arranged at two sides of the resistance net converter 30 and are used for providing air pressure at the front side and the rear side of the resistance net converter for the oral-nasal air flow detector so as to calculate pressure difference.
As shown in fig. 3, the body of the resistance net converter 30 is provided with resistance nets with different resistances at intervals. The mesh of the resistance net with lower resistance is thinner and the metal net wires are thinner than the resistance net with higher resistance.
As an example, as shown in fig. 3, a first resistance net 32 for detecting the oral airflow and a second resistance net 33 for detecting the nasal airflow are provided on a body 31 of a resistance net converter 30 at intervals. The mesh of the first resistance net 32 is thinner and the metal net wires are thinner than the second resistance net 33.
Upon oral flow detection, the resistive mesh transducer 30 is pushed so that the first resistive mesh 32 covers the port. Upon nasal airflow detection, the resistive mesh transducer 30 is pushed so that the second resistive mesh 33 covers the port. Thereby effecting a switching of the resistance net.
Preferably, the sealing strips which are in butt joint with the resistance net converter 30 are arranged on the slots, so that the slots are free from air leakage, and the detection accuracy is ensured.
Preferably, a temperature and humidity sensor (shown as temperature and humidity sensor 80 in fig. 2, located on the inner side of the tubular portion) or a separate temperature and humidity sensor is provided on the inner side of the middle portion of the airflow collector 20 for detecting the temperature and humidity of the airflow within the airflow collector 20.
Preferably, the airflow collector 20 is provided with an operating window 50 corresponding to the nose position. As shown in fig. 4, the body 54 of the operation window 50 is provided with a medicine feed hole 53. In the inactive state, the administration hole 53 is sealed by the seal 52. If nasal administration or physical stimulation is desired, seal 52 is torn off, the applicator is positioned on body 54, and the administration tube is threaded through air flow collector 20 from the dispensing orifice 53 and directed to the nostril of the patient.
Preferably, the periphery of the operation window 50 is provided with a clamping groove 51 matched with the medicine feeder, and the medicine feeder is clamped with the clamping groove 51 to realize the positioning of the medicine feeder and the body 54.
Preferably, the aperture of the administration hole 53 is slightly smaller than the outer diameter of the administration tube so that the two are in transition fit, ensuring the air tightness of the administration process.
Preferably, the air bag 10 is arranged on the port of the air flow collector 20 near the face, and the air bag 10 is provided with an air injection hole 40. The outer surface of the balloon 10 is secured with a plurality of attachment points 60 for securing the ends of the bungee cords 70.
When the gas collecting mask is used, the elastic rope 70 is wound around the head and neck of a patient to position the mask, then a proper amount of gas is injected into the air bag 10 through the gas injection hole 40 by using a syringe, and the air bag is attached to the face after being inflated, so that the face and the mask are sealed. The design of the air bag enables the mask to be suitable for patients with different facial shapes and facial sizes, and the application range is improved.
The application integrates structures such as air flow collection, resistance nets with different resistances, temperature and humidity sensors, administration operation windows, pressure collecting pipes and the like on the same air collecting mask, can realize comprehensive data collection of physical and chemical properties of air flow through the mouth and the nose, and simultaneously the operation windows provide possibility for physical/drug stimulation of the nasal cavity (for example, in the detection of allergic rhinitis, one term is called a nose excitation test, and the change of the nasal air flow is detected after allergen stimulation is actually given in the nasal cavity).
