According to the invention, when the cover body is expanded by conveying gas to the cover body through the gas inlet pipe, negative pressure can be formed in the bent pipe 17 and the pipe wall cavity by the gas flow of the gas inlet pipe, negative pressure is further generated in the cavity, mucus at the throat cavity part can enter the cavity through the opening 16 due to the generated negative pressure, so that the close contact surface can be tightly attached to the throat cavity of a human body on one hand, and the close contact surface can be tightly attached to the bottom of the cover body on the other hand, the elastic action is realized between the close contact surface and the bottom of the cover body due to the volume change of the cavity, and the bottom surface and the close contact surface are bonded by the.
In the embodiment of the present invention, as shown in fig. 1, the cover tube is provided with an intake control device 50 to control the intake airflow of the cover tube 20 into the cover body 10, specifically, the intake airflow can be set at a stable value, when the airflow is large, the intake control device can reduce the intake airflow, when the airflow is small, the intake control device can increase the intake airflow, the intake control device of the present invention has a mechanical structure, has no or few electrifying devices, reduces power consumption, and can be applied to a laryngeal mask.
As shown in fig. 5, the intake control device 50 includes a stopper 51, the stopper forms a first intake passage 52 and a second intake passage 53 in the cover tube 20, the first intake passage and the second intake passage are located at the middle position of the stopper, as shown in fig. 5, the first intake passage 52 and the second intake passage 53 are communicated, and the sectional area of the second intake passage 53 is smaller than that of the first intake passage 52, so that the flow velocity of the air flow is increased when the air flow passes through the second intake passage, and the detection accuracy is further improved. The air flow entering the enclosure 10 through the hood duct needs to pass through the first air intake passage 52 and the second air intake passage 53 in order.
A sliding sheet 55 is arranged in the first air inlet channel, an air passing hole 556 is arranged on the sliding sheet, a sliding groove 57 is arranged on the side wall of the first air inlet channel, the sliding groove is annularly distributed, the edge of the sliding sheet is positioned in the sliding groove, the sliding sheet can move in the sliding groove to change the size of the air passing hole in the first air inlet channel, an air pressure channel 54 is arranged in the first block 51, one end of the air pressure channel extends to the second air inlet channel 53, the other end extends into the sliding groove, one end of the sliding sheet is provided with a first pull rod 551, the tail end of the first pull rod is provided with a first piston 552 positioned in the air pressure channel 54, the other end of the sliding sheet is provided with a second pull rod 553, the tail end of the second pull rod is provided with a second piston 554, an air pressure control unit 56 is arranged in the block 51, the air pressure control unit can control the air pressure on the end part of the second piston, so that the air pressure on the end part keeps a constant state when the second piston moves; the gas flow rate through the second inlet channel changes, and then the gas pressure in the gas pressure channel 54 changes, and then the first piston moves to drive the sliding piece to move, and the sliding piece moves to change the size of the gas hole in the first inlet channel so as to restrain the change of the gas flow rate of the second inlet channel.
As shown in fig. 7, the pneumatic control unit 56 includes a control chamber 561, the second piston is located in the control chamber 561, the second piston divides the control chamber 561 into a first portion and a second portion, as shown in fig. 7, the left side of the second piston is the first portion, and the right side of the second piston is the second portion. The second piston can move in the control chamber to change the volume of first portion and second portion, first portion and outside intercommunication, and when the second piston moved, the atmospheric pressure of second portion can be fixed, and the second piston is connected with and is located interference rod 555 in the second portion, and when the atmospheric pressure of second portion was less than first portion, interference rod 555 can prevent the second piston to move towards the direction of second portion. When the gas flow rate in the second gas inlet channel needs to be controlled to be larger, the gas pressure of the second part can be controlled to be a lower value at this time, the slide plate can move only by the lower gas pressure value in the gas pressure channel, and then the gas flow rate in the second gas pressure channel is controlled to be a larger value. By the same token, the steady air flow in the second air pressure passage can be reduced by increasing the constant air pressure of the second portion.
In a preferred embodiment, the second portion is connected to an air pressure sensor, the air pressure sensor is connected to a controller 562, the second portion is connected to a first air pipe 563 connected to the outside, the first air pipe is provided with an air pump 564, the controller controls the air pump, and the controller controls the air pump according to data of the air pressure sensor, so as to further maintain the air pressure of the second portion at a set value.
