A better treatment method is to directly spray medicine at the diseased site. When treating these diseases, doctors often prescribe some powder medicines or medicaments that need to be diluted with water, and use a spraying device to directly act the medicament on the throat affected part to help the patient reduce inflammation and relieve pain; The commonly used method at present is to suck the liquid medicine with a syringe without a needle and then spray the liquid medicine at the diseased site. However, the liquid medicine sprayed by the syringe is in the form of a water column, and it cannot fully disperse when contacting the throat, with a small diffusion area, and cannot be evenly sprayed on the diseased site, resulting in poor absorption effect of the liquid medicine; and because the liquid medicine is continuously sprayed directly at the throat, it is very difficult for medical staff to control the dosage of the liquid medicine. The liquid medicine is easy to gather on the throat and flow downward, which is likely to cause waste of the liquid medicine and further affect the absorption effect of the liquid medicine, thus increasing great work difficulty for medical staff; Based on this, the present invention provides a pressurized sprayer for respiratory medicine to solve the problems raised in the above background art.

The intermittent rotation of the fourth bevel gear 42 drives the sixth rotating shaft 43 to rotate intermittently. The intermittent rotation of the sixth rotating shaft 43 drives the third rotating disc 45 to rotate intermittently. The intermittent rotation of the third rotating disc 45 drives the third sliding column 46 to rotate intermittently; Since the first ends of two second rotating rods 49 are respectively fixedly sleeved on the infusion tubes 410 above the two connecting plates 106, and the same sliding rod 48 is installed between the second ends of the two second rotating rods 49, a sleeve 47 is slidably installed on the sliding rod 48, and the first end of the third sliding column 46 is connected to the sleeve 47. The second end of the third sliding column 46 slidably penetrates through the eccentric position of the third rotating disc 45; The third sliding column 46 is intermittently rotated to drive the sleeve 47 to rotate intermittently. The intermittent rotation of the sleeve 47 drives the sliding rod 48 to swing intermittently back and forth around the infusion tube 410. The intermittent reciprocating swing of the sliding rod 48 around the infusion tube 410 drives the second rotating rod 49 to swing intermittently back and forth around the infusion tube 410. The intermittent reciprocating swing of the second rotating rod 49 around the infusion tube 410 drives the infusion tube 410 to swing intermittently back and forth. The intermittent reciprocating swing of the infusion tube 410 drives the medicine spraying head 4 to swing intermittently back and forth. The intermittent reciprocating swing of the medicine spraying head 4 is used to fully disperse the liquid medicine when it contacts the throat, increasing the area of liquid medicine diffusion and enabling the liquid medicine to be evenly sprayed on the diseased part, further improving the absorption effect of the liquid medicine.
[0018] By providing an intermittent mechanism, the present invention realizes the intermittent rightward movement of the piston plate and thus intermittently sprays medicine on the diseased throat part of the patient, preventing continuous spraying of medicine directly onto the throat. It is difficult for medical staff to control the amount of sprayed medicine, and the liquid medicine is likely to accumulate on the throat and flow downward, which may easily cause waste of the liquid medicine. At the same time, intermittent spraying gives the throat sufficient time to absorb the liquid medicine, and the liquid medicine sprayed on the throat is gradually absorbed by the throat, ensuring the absorption effect of the liquid medicine. By providing a stirring mechanism, the present invention realizes the intermittent rightward movement of the piston plate and thus intermittently sprays medicine on the diseased throat part of the patient. At the same time, intermittent spraying gives the throat sufficient time to absorb the liquid medicine, and the liquid medicine sprayed on the throat is gradually absorbed by the throat, ensuring the absorption effect of the liquid medicine. At the same time, the stirring rod rotates to continuously stir the mixed liquid medicine in the medicine spraying cylinder, avoiding the precipitation of the mixed liquid medicine due to standing still, which may affect the efficacy. By providing a swinging mechanism, the present invention realizes the intermittent rightward movement of the piston plate and thus intermittently sprays medicine on the diseased throat part of the patient. At the same time, intermittent spraying gives the throat sufficient time to absorb the liquid medicine, and the liquid medicine sprayed on the throat is gradually absorbed by the throat, ensuring the absorption effect of the liquid medicine. At the same time, the stirring rod rotates to continuously stir the mixed liquid medicine in the medicine spraying cylinder. At the same time, the medicine spraying head swings intermittently back and forth to fully disperse the liquid medicine when it contacts the throat, increasing the area of liquid medicine diffusion and enabling the liquid medicine to be evenly sprayed on the diseased part, further improving the absorption effect of the liquid medicine. The structure of the present invention is simple and reliable, with good medicine spraying effect for patients in the respiratory department, convenient control, and is suitable for popularization.
[0019] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
