Background technique

More than 70% of human diseases are related to the environment, and the environment has the greatest impact on the human respiratory system. The most effective, common and most acceptable way to deliver drugs to patients is to deliver oral drugs through Oral delivery, but the drug is easily broken down in the digestive tract, so the drug delivery route through the mouth, nose, and lungs has been developed. Directly enter the bronchi, and then diffuse to the entire alveoli, the effect is more efficient and direct than ordinary oral drugs.

The existing atomizer consists of a cylinder body, a mist-making structure connected to the bottom of the cylinder body, a "T"-shaped tube connected to the top of the cylinder body, and sleeves respectively connected to both ends of the "T"-shaped tube And a buffer tube, the medicine liquid is preset in the tube and atomized by the mist making structure, the free end of the buffer tube is an open space, the patient bites the jacket tube and absorbs the medicine mist.

When the patient inhales, the drug mist enters the respiratory tract from the cylinder body through the "T" tube and the cannula, and inhales the outside air through the buffer tube to supplement the patient's inhalation volume.

When the patient stops inhaling, the nebulizer still continues to produce the drug mist, and dissipates from the buffer tube to the outside, or when the patient exhales, the exhaust gas is discharged to the outside through the sleeve and the buffer tube, but the drug mist is also released. Blowing away causes waste and pollutes the environment, and the actual use efficiency of the amount of liquid medicine preset in the barrel is not good. If a necessary course of treatment is to be achieved, the amount of liquid medicine preset must be increased, thereby increasing medical expenses.

The method of using the utility model to manufacture medicine mist to provide inhalation, please refer to Figure 4 to Figure 7, first fill and store a medicine 400 in the chamber 111, the medicine 400 is used to treat diseases of the human body, the liquid of the medicine 400 The surface height does not exceed the compressed gas inlet 212 , and the medicament 400 will flow into the fluid channel 221 .

Infuse a compressed gas 500 from the gas delivery tube 311. Generally speaking, the compressed gas 500 is compressed oxygen. The compressed gas 500 circulates in the gas delivery tube 311 and the compressed gas channel 211. When the patient needs to take medicine, the trigger arm is pulled at this time 321 , the trigger arm 321 rotates through the pivot portion 313 and drives the valve 322 to close the pressure relief hole 312 , and at the same time presses the outer periphery of the elastic arm 323 with the pressing rod 324 to make it bend and deform to store the elastic restoring force.

When the valve 322 seals the pressure relief hole 312, the only flow path for the compressed gas 500 is to flow through the gas delivery pipe 311 and then enter the compressed gas channel 211, and then the compressed gas 500 enters the smaller compressed gas inlet 212 from the compressed gas channel 211 , the Venturi effect occurs, that is, the compressed gas 500 sucks the medicament 400 out of the fluid channel 221 .

The compressed gas 500 attracts the medicine 400 and impacts the medicine 400 to make it thinner. The thinned medicine 400 is sprayed by the compressed gas 500 and hits the stopper 230, making it splash and atomized and mixed with the compressed gas 500 to form a medicine. The mist 600 is sprayed around, and most of the medicine mist 600 will be filled in the air intake channel 123 .

The patient clamps the convex tube 113 with his mouth, and inhales the drug mist 600 in the air intake channel 123 into the lungs through the chamber 111, the mixed gas channel 129, and the mixed gas outlet 112, and the patient's inspiratory force The one-way intake valve 127 will open the intake hole 125 and the one-way exhaust valve 128 will tightly close the exhaust hole 126 .

At this time, outside air can enter the air inlet 125 to supplement the patient's inspiratory volume, and at the same time, most of the medicine mist 600 can be guided to the mixed gas outlet 112 for the patient to inhale without inhaling. Excessive air can increase the absorption efficiency of the medicament 400 and reduce the treatment time.

After inhaling the medicine, the patient must exhale again to discharge the waste gas in the lungs. The patient's exhalation force will cause the one-way exhaust valve 128 to open the exhaust hole 126, and the exhaust gas exhaled by the patient will pass through the mixed gas outlet 112 And the exhaust channel 124 is exhausted to the outside, and is filtered by the filter material 130 at the same time, so as to prevent the virus or bacteria in the exhaust gas from spreading to the outside and affecting the hygienic environment.

At this time, due to the disappearance of the suction force, the one-way intake valve 127 recloses the exhaust hole 126, so that the medicine mist 600 will not be lost, reducing unnecessary waste, and because the channel cross-sectional area of the mixed gas channel 129 is much smaller than that of the exhaust gas. The channel cross-sectional area of the channel 124 makes it difficult for the exhaust gas to enter the chamber 111 and most of it is exhausted from the exhaust channel 124 to the outside.

When the patient wants to stop inhaling the medicine mist 600, he only needs to release the trigger arm 321, then the deflected elastic arm 323 returns to its original shape with its elastic restoring force and elastically pushes against the pressing rod 324, thereby connecting the valve 322 and the pressure relief hole. 312 breaks away from the seal, so that the pressure relief hole 312 is opened.

When the pressure relief hole 312 is opened, since the aperture size of the pressure relief hole 312 is much larger than the aperture size of the compressed gas inlet 212, the compressed gas 500 will flow to the position where the obstruction is small, thus causing the compressed gas 500 to escape from the pressure relief hole 312 To the outside world without entering the compressed gas inlet 212, in this way the generation of the drug mist 600 is stopped.

The utility model has considerable convenience in use, the patient only needs to continuously pull the pressing mechanism 300 to absorb the medicine mist 600, release the pressing mechanism 300 and no medicine mist 600 will be produced, so the waste of medicine 400 and medicine mist 600 can be reduced , so as to greatly improve the medication efficiency and medical effect, and during the treatment process, the patient blows air but does not discharge the medicine mist 600 from the chamber 111, which can effectively preserve the medicine 400 and medicine mist 600. In addition, the patient blows out The exhaust gas will be filtered by the filter material 130 to prevent the virus or bacteria in the exhaust gas from spreading to the outside and maintain a hygienic environment.

Of course, the utility model can also have other various embodiments, and those skilled in the art can make various corresponding changes and deformations according to the utility model without departing from the spirit and essence of the utility model, but These corresponding changes and deformations should all belong to the protection scope of the appended claims of the present utility model.
