Detailed Description
The following describes the embodiments of the present invention in detail with reference to specific examples.
Example 1
The pneumatic atomization drug delivery device of the embodiment, as shown in fig. 1 to 5, comprises an atomization end and a drug delivery end, wherein the atomization end is provided with an atomization tank 1, the bottom of the atomization tank 1 is provided with a primary nozzle 2, the lower end of the primary nozzle 2 is provided with a primary air inlet 3, and the outlet of the primary nozzle is provided with a liquid spray port 4; the top of the tank body is provided with a mist outlet 5; the drug delivery end is provided with an atomizing bottle 6 and a liquid medicine bottle 7 which is connected with a liquid spraying port 4 of the tank body through a liquid medicine pipe 8; the bottom of the atomizing bottle is provided with a secondary nozzle 9, the lower end of the secondary nozzle is provided with a secondary air inlet 10, the outlet of the secondary nozzle is provided with an atomizing nozzle 11, the atomizing nozzle is connected with the atomizing outlet of the tank body through an aerosol pipe 12, the top of the atomizing bottle is provided with a breathing port 13, and the breathing port is connected with an oxygen mask 14; the first-stage air inlet 3 is connected with a first-stage air inlet pipe 15, and the second-stage air inlet 10 is connected with a second-stage air inlet pipe 16. Wherein, the first-stage air inlet pipe is connected with a high-pressure air source, and the second-stage air inlet pipe is connected with a low-pressure air source. Or the first-stage air inlet pipe and the second-stage air inlet pipe can be connected with the same air source, and the air pressure distribution of the first-stage air inlet pipe and the second-stage air inlet pipe is adjusted through the valve 17. The gas source can adopt oxygen or compressed air.
In this scheme, the atomizing jar is as main atomizing container, and the one-level air inlet provides high-pressure large-traffic air supply, and the liquid medicine is spout along the hydrojet mouth through the liquid medicine pipe, and high velocity air carries out high-efficient atomizing to the liquid medicine. Meanwhile, the atomization tank is also used as a mist storage container. The atomized gas fog enters the second-stage nozzle along the gas fog pipe and is atomized by the gas flow sprayed from the second-stage air inlet. The air source of the second-stage atomization adopts low-flow airflow, reduces noise, and further atomizes and dilutes the aerial fog led out from the atomization tank. Atomizing jar and atomizing bottle adopt the hose connection, and the patient wears oxygen mask during the treatment and atomizes inhalation treatment, and patient's head is kept away from to the atomizing jar as the main noise source, can not produce obvious noise influence, is applicable to children aerosol treatment.
In this scheme, as shown in fig. 2, be equipped with pipette 18 in the atomizing jar, pipette one end is connected to the atomizing tank bottom, and the other end is connected to the exit of one-level nozzle through venturi. The hydrops that condenses the production in the atomizing jar can circulate to one-level nozzle through the pipette and circulate the atomizing, prevents that the liquid medicine from at the internal deposit of atomizing jar.
In addition, as shown in fig. 3, a gas phase balance tube 19 is connected between the liquid medicine bottle and the atomizing bottle. The arrangement of the gas-phase balance tube can ensure that the liquid medicine can smoothly flow to the liquid spraying port from the liquid medicine bottle.
Most of medicine loss in the aerosol treatment is caused by periodic breathing action, and when the conventional oxygen mask is used for the aerosol treatment, the mask is filled with aerosol all the time, and only when a patient inhales, the aerosol can enter a respiratory tract, and when the patient exhales, the aerosol in the mask can be discharged to the outside along a gap between a breathing valve or the mask and the face, so that a large amount of medicine loss is caused.
Aiming at the problems, the scheme is improved as follows, for example, as shown in fig. 5, the oxygen mask is provided with a breather valve, the breather valve is provided with a round through hole 20, the front end and the rear end of the through hole are both provided with limits, a foam ball 21 is arranged in the through hole, and the foam ball can move back and forth along the through hole. The front end of the through hole is communicated with the oxygen mask, the side wall is provided with a front opening 22 and a rear opening 23, and the front opening and the rear opening are at a distance from the limiting position. The front opening is provided with an expiration pipe communicated with the outside, the expiration pipe is provided with a one-way valve 24, the rear opening is communicated with a respiration port of the atomization bottle, and the rear end of the through hole is communicated with the expiration pipe.
In the exhalation process, the foam ball moves towards the rear end of the through hole, when the foam ball moves to the rear part of the front opening, the exhalation tube is communicated with the inside of the oxygen mask, and the exhaled gas is exhausted along the exhalation tube. When the foam ball moves to the rear of the rear opening, the breathing port is communicated with the oxygen mask, and the aerial fog in the atomizing bottle is filled into the oxygen mask until the expiration process is finished. In the air suction process, the foam ball moves towards the front end of the through hole, when the foam ball moves to the front of the rear opening, the breathing opening is separated from the front end of the through hole, and aerial fog does not directly enter the oxygen mask from the front opening. Most of the aerial fog filled into the oxygen mask in the exhalation process is inhaled, the residual quantity of the aerial fog of the oxygen mask is small, and the quantity of the medicine discharged along with the exhalation is greatly reduced in the next exhalation process, so that the medicine loss can be reduced.
On the other hand, the improvement is that as shown in figure 4, a first-stage air inlet pipe is provided with an air inlet valve, and a medicine liquid pipe is provided with a liquid inlet valve; an impeller 25 driven by airflow is arranged in the secondary air inlet pipe, and a rotating shaft of the impeller is in transmission connection with an air inlet valve rod 27 and a liquid inlet valve rod 28. The air flow of the secondary air inlet pipe drives the impeller to rotate, the air inlet valve rod and the liquid inlet valve rod are synchronously controlled by the impeller to rotate, the air inlet valve and the liquid inlet valve are controlled to be periodically opened and closed, and the periodic pneumatic atomization in the atomization tank is realized. The improvement allows for control of the total amount of airflow into the aerosol can without reducing the pressure and flow rate of the airflow during the aerosol can atomization.
In this scheme, the one-level nozzle is located and is close to jar side wall department, and the case axis of admission valve and feed liquor valve is parallel with the impeller axis, and the outer wall of atomizing jar is equipped with gear box 29, and admission valve rod 27, feed liquor valve rod 28 and impeller 25 pivot all extend to the gear box in, and the impeller pivot is located between admission valve rod and the feed liquor valve rod, passes through gear drive between impeller pivot and admission valve rod, the feed liquor valve rod.
