Preferred embodiments of the present utility model may also have the following additional technical features:
in this embodiment, the air-blocking cavity 1012 is disposed on the air-containing device 10 and located at one side of the air outlet channel 30 and is communicated with the air outlet channel 30, and the air-blocking cavity 1012 is mainly disposed to facilitate the installation of the air-blocking member 40; the air blocking piece 40 is adjustably disposed in the air blocking cavity 1012 and can extend into the air outlet channel 30, so that the flow rate of the air entering the air containing device 10 into the air outlet channel 30 can be controlled by adjusting the extension and retraction amount of the air blocking piece 40 extending into the air outlet channel 30.
In other embodiments, the air blocking cavity 1012 may also be disposed at an angle with respect to the air outlet channel 30, for example, the angle between the air blocking cavity 1012 and the air outlet channel 30 is set at 60 ° or 45 °, so that the angle between the air blocking member 40 disposed in the air blocking cavity 1012 and the air outlet channel 30 is also set at 60 ° or 45 °, and thus the amount of the output air flow of the air inlet and outlet channel 30 can be controlled by adjusting the expansion and contraction amount of the air blocking member 40 extending into the air outlet channel 30, which is not limited herein.
In the present embodiment, the air container 10 includes a mounting base 101 and an air container 102, and the air container 102 is fixed on a surface of the mounting base 101, so that an air container 104 is formed between the air container 102 and the mounting base 101. Wherein, the gas transmission channel is arranged on one side of the mounting seat 101 and is communicated with the gas chamber 104, and the gas outlet channel 30 is also arranged on one side of the mounting seat 101 and is communicated with the gas chamber 104. Thus, the gas of the gas source enters the gas delivery channel, enters the gas accommodating chamber 104, and then enters the gas outlet channel 30 for output. Of course, a sealing gasket 103 is provided at the junction of the gas tank 102 and the mount 101, and the gas placed into the gas chamber 104 through the sealing gasket 103 leaks from the gap at the junction between the gas tank 102 and the mount 101.
It should be noted that, the air chamber 104 is designed to have a fixed capacity, and the specific capacity of the air chamber 104 can be set according to the actual requirement, for example, 30ml to 40ml, and of course, the capacity of the air chamber 104 can also be 50ml or 55ml, so long as the air inlet channel 20 can be ensured to synchronously and rapidly fill the air chamber 104 and reach the pressure requirement required by the air chamber 104 in the air inlet state, and sufficient airflow in the air chamber 104 can be ensured to be continuously output into the pressure collecting pipe so as to continuously purge the pressure collecting pipe, so that the specific capacity of the air chamber 104 is not limited. It can be seen that the gas chamber 104 is equivalent to a buffer chamber, and after the gas of the gas source enters the gas chamber 104 through the gas inlet channel 20, the pressure fluctuation can be reduced under the buffer action of the gas chamber 104, so as to ensure the stability of the output purge gas flow.
It should be noted that, the gas of the gas source in this embodiment comes from the exhalation branch of the ventilator, and specifically may be connected to the exhalation branch of the breathing circuit of the ventilator through a branch pipe, so, in the inhalation state, the gas source may enter the gas inlet channel 20 and enter the gas chamber 104 and be stored in the gas chamber 104 in the process of introducing the gas into the exhalation branch of the breathing circuit, without having to purge the separate gas source, so as to reduce the cost of the ventilator. It will be appreciated that the gas chamber 104 has the additional function of storing sufficient gas in the gas chamber 104 to continue to enter the pressure tube through the gas outlet channel 30 for purging even during a ventilator standstill.
Of course, the air blocking cavity 1012 communicated with the air outlet channel 30 is also arranged on the mounting seat 101, when the breathing machine is in a working state, one air flow in the expiration branch enters the breathing system of a patient, and the other air flow enters the air outlet channel 30 after entering the air accommodating chamber 104 through the air inlet channel 20, and the air flow entering the air outlet channel 30 from the air accommodating chamber 104 controls the air flow output by the air outlet channel 30 by adjusting the expansion and contraction amount of the air blocking piece 40 entering the air outlet channel 30, so that the flow of the purge air entering the pressure collecting pipe is controlled.
It should be noted that, the air blocking cavity 1012 is disposed perpendicular to the air outlet channel 30, that is, the expansion direction of the air blocking member 40 expands and contracts along the direction perpendicular to the air outlet channel 30, so as to enter the air outlet channel 30 to control the flow of the air output by the air outlet channel 30, so that the flow of the air output by the air outlet channel 30 can be quickly adjusted.
In this embodiment, the specific structure of the air blocking member 40 includes a knob adjusting part and a flow limiting part 401 connected to each other, and the knob adjusting part is used for controlling the expansion and contraction amount of the flow limiting part 401 from the air blocking cavity 1012 into the air outlet channel 30. That is, it can be understood that the flow restrictor 401 can extend into the air-blocking cavity 30 from the air-blocking cavity 1012 or retract into the air-blocking cavity 1012 from the air-blocking cavity 30 under the driving of the knob adjusting part, so as to achieve the purpose of adjusting the air-blocking cavity 30 to output the purge air flow into the pressure production pipe.
In this embodiment, an external thread is disposed on the outer wall of the knob adjusting portion, and an internal thread in threaded connection with the external thread is disposed on the inner wall of the air-blocking cavity 1012, so that the expansion and contraction amount of the flow restrictor 401 entering the air outlet channel 30 can be controlled by controlling the tightening depth between the external thread and the internal thread, thereby facilitating the control of the flow of the air output from the air outlet channel 30. Of course, an adjusting groove 4021 is provided on the end surface of the knob adjusting part facing away from the flow limiting part 401, and when the flow of the gas output by the gas outlet channel 30 is controlled by driving the flow limiting part 401 by the adjusting knob adjusting part, the knob adjusting part can be rotated by inserting a screwdriver tool into the adjusting groove 4021, so as to achieve the purpose of adjustment.
In this embodiment, the air resistor 40 further includes a connection portion 403 to facilitate the installation of the sealing gasket 103, and of course, in order to further facilitate the installation of the sealing gasket 103, a receiving groove 4031 is provided on an outer wall of the connection portion 403 along a circumferential direction thereof, and the sealing gasket 103 is installed in the receiving groove 4031. The knob adjusting part is connected with the current limiting part 401 through the connecting part, the outer diameter of the connecting part 403 is larger than the outer diameter of the current limiting part 401 but smaller than the outer diameter of the knob adjusting part, and a sealing gasket is arranged between the outer wall of the connecting part 403 and the air resistance cavity 1012. It can be seen that the sealing gasket is sleeved on the connecting portion 403, and the outer wall of the sealing gasket is connected and sealed with the inner wall of the air blocking cavity 1012, so that leakage of air from the air blocking cavity 1012 to the outside of the mounting seat 101 is avoided.
In this embodiment, an annular step surface 1014 is disposed in the air lock chamber 1012 along the circumferential direction thereof, and the sealing gasket is pressed against the annular step surface 1014 to prevent the gas in the gas outlet channel 30 from being discharged from the air lock chamber 1012, so that the outer wall of the sealing gasket cannot rub with the inside of the air lock chamber 1012 to abrade the sealing gasket in the process of driving the flow restrictor 401 to expand and contract by the adjusting knob portion 402, thereby improving the service life of the sealing gasket and the sealing performance of the sealing gasket.
In this embodiment, the flow restrictor 401 is a tapered rod, one end of the tapered rod with a smaller outer diameter faces the air outlet channel 30, and the maximum outer diameter of the tapered rod is equal to or slightly smaller than the inner diameter of the air outlet channel 30, so that the stepped adjusting effect is achieved when the flow of the air output by the air outlet channel 30 is adjusted through the flow restrictor 401, and the adjusting effect is better. Of course, the channel of the air blocking cavity 1012 communicated with the air outlet channel 30 is a tapered channel matched with the tapered rod, and the clearance between the tapered rod and the channel of the air blocking cavity 1012 communicated with the air outlet channel 30 can be prevented from being larger by the tapered channel, so that the air in the air outlet channel 30 is reduced from entering the air blocking cavity 1012.
In this embodiment, the channel for communicating the air chamber 104 with the air outlet channel 30 is an air flow channel 1011 disposed on the mounting seat 101 and communicating the air blocking chamber 1012 and the air chamber 104, since one end of the air flow channel 1011 is communicated with the air chamber 104, the other end of the air flow channel 1011 is communicated with the air blocking chamber 1012, and the air blocking chamber 1012 is communicated with the air outlet channel 30 through the communicating channel 1013 (tapered channel), thereby achieving the purpose of communicating the air chamber 104 with the air outlet channel 30. Of course, the end of the air flow channel 1011 communicating with the air lock chamber 1012 is located between the sealing gasket and the communicating channel, so as to avoid the leakage of the air entering the air lock chamber 1012 from the air chamber 104. It can be seen that the gas in the gas chamber 104 enters the gas-proof cavity 1012 through the gas flow channel 1011, and the gas entering the gas-proof cavity 1012 is forced to enter the gas outlet channel 30 through the tapered channel under the sealing action of the sealing gasket, and finally is input into the pressure production pipe for purging. Of course, the maximum outer diameter of the tapered flow-limiting rod is larger than the maximum inner diameter of the tapered channel, and for this, those skilled in the art will understand that by adjusting the expansion and contraction amount of the tapered flow-limiting rod driven by the rotation adjusting part into the tapered channel, the flow rate of the gas entering the gas outlet channel 30 can be adjusted, so as to control the gas flow rate in the gas outlet channel 30 delivery pressure pipe.
It should be noted that two air outlet channels 30 are provided in this embodiment, so that a path for purging the pressure sensor is added in the pressure production pipe, and the purging effect is improved; of course, 2 air blocking members 40 are also provided corresponding to the number of air outlet passages 30, i.e., one adjustable air blocking member 40 corresponds to one air outlet passage 30. In other embodiments, three or four air outlet channels 30 may be provided, which is not limited herein.
Preferred embodiments of the present utility model may also have the following additional technical features:
the utility model also comprises a switching valve 50, wherein the switching valve 50 is arranged on the surface of the mounting seat 101, which is opposite to the air container 102, the switching valve 50 is communicated with the air inlet channel 20 and the air container 104 on the mounting seat 101 to form a passage, and after entering the air inlet channel 20, the air enters the air container 104 through the switching valve 50, so that the switching valve 50 is equivalent to a switch control valve of the air inlet channel 20 to control the on-off of the air entering the air container 104. In this way, when the ventilator is in the exhalation state, the switching valve 50 is closed, so that the gas in the gas chamber 104 will not flow back through the gas inlet channel 20, and the gas in the gas chamber 104 can be ensured to be sufficient and continuously enter the pressure production pipe through the gas outlet channel 30 for purging.
The above additional technical features can be freely combined and superimposed by a person skilled in the art without conflict.
The foregoing is only a preferred embodiment of the present utility model, and all technical solutions for achieving the object of the present utility model by substantially the same means are within the scope of the present utility model.
