The present invention relates to a method for protecting a ventilation device of a ventilator against backflowing exhaled air, and to a ventilator. A respiratory gas flow is generated by a blower device and is guided via a flow connection to a breathing interface. The respiratory gas flow is adjusted with the aid of a control device to a first ventilation pressure during an inhalation phase of the patient and to a second ventilation pressure during an exhalation phase. A characteristic variable for a flow within the flow connection is detected by a device for monitoring backflowing exhaled air. A back pressure with respect to the backflowing expiratory flow is adjusted by a specific increase of the ventilation pressure taking into consideration the characteristic variable, whereby an undesirable rebreathing into the ventilation device is counteracted by the back pressure.

The invention discloses a pulmonary function rehabilitation training device for respiratory internal medicine, which comprises a shell, an exhalation cavity, an inhalation cavity, air holes, an exhalation tube, an inhalation tube and a mask, and an exhalation cavity is arranged inside the shell And an air suction chamber, the left side of the air suction chamber is provided with a flip door installed on the shell, and the interior of the air suction chamber is provided with a sponge pad, and the sponge pad is laid on the upper end surface of the baffle. The pulmonary function rehabilitation training device used in respiratory medicine also adopts a dual-pipe training structure in the device, which can adjust the internal structure of the mask according to the actual needs of the patient, and can be used both with mouth and nose or with simple oral breathing. To achieve the purpose of rehabilitation training, there is no need to remove the mask repeatedly, and the inside of the device can be heated to avoid condensation of a large amount of water droplets inside the device when exhaling, and at the same time, the inhaled air can be heated, humidified and added to ensure lung function recovery The effect of training.

The invention provides an oral breathing rod with its own adjustment function, which includes a connecting cylinder, an air delivery cylinder cavity, an air inlet hole, a filter screen, a sealing ring, a blocking ring, a storage box, a box cavity, a telescopic rod, a sleeve and an adjustment bolt , assembly tube structure, breathing head structure, matching belt structure and sleeve mesh cylinder structure, the air delivery cylinder cavity is opened in the interior of the connecting cylinder, and the assembly tube structure is inserted on the inner side; the air inlet hole is opened in the The middle part of the front surface of the connecting cylinder; the filter screen is inserted in the middle part of the cavity of the gas delivery cylinder; the sealing ring is glued on the outer side of the blocking ring, and the outer side of the blocking ring is in close contact with the inner side of the connecting cylinder and the retaining rings are respectively glued on the left and right sides of the outer wall of the assembled pipe structure. The beneficial effects of the present invention are: through the arrangement of the assembly tube structure, it is beneficial to absorb the water mist in the exhaled gas when the gas exhaled by the patient passes through the fastening pad, thereby preventing the water mist of the patient's exhaled gas from affecting the oral breathing Great use.

The invention discloses a device and method for replacing a medicine tank. A device for replacing a medicine tank includes a shell, a breathing channel and a pushing part. The first port and the second port; the respiratory channel has a third port that divides the interior of the respiratory channel into the first channel and the second channel, and the respiratory channel communicates with the first port through a diverter, and the diverter is provided with an inlet; the push part The first end of the pusher has a communication hole, the second end of the pusher is placed in the cavity through the third opening, the second end of the pusher can move along the first preset mode to push the medicine tank in the cavity out from the outlet, and the pusher The portion has a first state of disconnecting the first channel from the second channel and a second state of connecting the first channel and the second channel through the communication hole. When the medicine tank needs to be replaced, the pushing part is pushed by hand, and the pushing part pushes the medicine tank out from the outlet along the first preset direction, and the communication hole connects the first channel and the second channel, switches to a breathing channel, and replaces the medicine tank.

The invention discloses a non-contact mouth breathing detection device, method and storage medium, comprising: using a thermal imager module to non-contactly collect the temperature of different positions of the face of the target to be measured and generating a sequence of infrared thermal images; using a steering gear The module receives the pulse signal from the processor, and adjusts the acquisition direction of the thermal imager module; the processor receives the infrared thermal image sequence of the thermal imager module and locates the position of the face in the infrared thermal image, and adjusts the thermal imager module. The acquisition direction makes the face to be tested be located in the detection area, locate the nostril and mouth two regions of interest from the infrared thermal image of the face, and judge whether the target to be tested is Perform mouth breathing and mouth breathing intensity, and generate a breathing report. The invention can distinguish whether the target to be tested is mouth breathing or nasal breathing, can generate a breathing report of the target to be tested during sleep, and will not affect the user's sleep.

A protective device for alcohol cardiomyopathy in the Department of Cardiology, which relates to the technical field of medical equipment. Two grooves are arranged on the lower jaw support end of the head support frame, and a mouth opening mechanism is installed in the groove, and the mouth opening mechanism A respiratory rate sensor is installed on the stretched end of the device; a protective device for alcohol cardiomyopathy in the Department of Cardiology according to the present invention supports the head of the drunk person through the head support frame, so as to prevent the head of the drunk person from being skewed and affecting the drunk person Open the mouth of the drunk person through the mouth opening mechanism to prevent the drunk person from vomiting and not opening the mouth in time, causing foreign objects to block the oral breathing tube. The breathing state of the drunk person is detected by the respiratory rate sensor, and the The information is transmitted to the single-chip microcomputer, and the oxygen supply mechanism and the button-type alarm are started through the single-chip microcomputer, and the oxygen is delivered to the nasal airway through the oxygen supply mechanism, and the button-type alarm is used for warning, so that others can find it in time.

The invention relates to a bio-piezoelectric intelligent mask, which comprises a mask body. Hanging ears and breathing windows are arranged on both sides of the mask body. A mask filter element is arranged in the breathing window. The mask filter element is composed of multiple layers of mutually insulated films. Each layer of film From left to right, it is composed of the first electrode layer, the first core material layer, the air-permeable layer, the second core material layer, and the second electrode layer. The core material layer is made of biological piezoelectric hydrogel, and the center position transparent window, and an intelligent control device is also arranged on the mask body. The invention also discloses an intelligent control method of the bio-piezoelectric intelligent mask. The present invention can generate electric energy under the respiratory air pressure, so as to have the function of electrostatic adsorption of dust and viruses; at the same time, the present invention can realize the matching of the working voltage of the filter element with the human respiratory air pressure through the intelligent control device, and predict and compensate the air pressure based on data mining technology. Working voltage, so as to ensure smooth breathing, filterability, adsorption and energy saving when used for a long time.
