Technical Field

[0001] The present invention relates to a lung-clearing and phlegm-discharging device, and more particularly to a lung-clearing and phlegm-discharging device for respiratory care. Background Art

[0002] The respiratory department is one of the traditional departments of internal medicine, a secondary clinical department belonging to the internal medicine system. The main diseases it treats are respiratory system diseases. Common diseases include upper respiratory tract infections, such as colds, pharyngitis, laryngitis, tonsillitis, etc. There are also lower respiratory tract infections, often diagnosing acute and chronic bronchitis, pneumonia, bronchiectasis, lung abscess, pulmonary tuberculosis, etc. In addition, airway obstructive diseases are also within the scope of practice of the respiratory department, such as bronchial asthma, chronic obstructive pulmonary disease, bronchiectasis, etc.

[0003] During the process of respiratory care, it is often necessary to discharge phlegm from patients to slow down their conditions. In the prior art, phlegm clearing in nursing often only uses the method of patting the patient's back by hand to make them cough up the phlegm dryly. On the one hand, the germs in the phlegm are likely to enter the external air, causing pollution. On the other hand, it makes the patient cough more severely, and it is also inconvenient for nurses to take and place the phlegm and for sampling and testing the phlegm.

[0004] In view of this, the present invention designs a lung-clearing and phlegm-discharging device for respiratory care. Summary of the Invention

Initially, an adjusting piston plate and a second fine hole plate block the oxygen delivery pipe, and oxygen can pass through the small holes on the second fine hole plate. And the small working motor drives the trimming rod to rotate 90 degrees, making the first fine hole plate rotate to the original position of the second fine hole plate, and then an adjusting piston plate and the first fine hole plate block the oxygen delivery pipe, and oxygen can pass through the small holes on the first fine hole plate, thus completing the switching between the two to adjust the oxygen delivery pressure according to the patient's condition, and the use effect is better.

[0046] The U-shaped positioning tool 1 of the device can be clamped on the bed frame or railing of the hospital bed. Twist the hand-twist nut 19 to make the locking screw 17 drive the pressing plate 18 to clamp the bed frame. On the one hand, it strengthens the firmness of the positioning. On the other hand, it can adapt to hospital beds or railings of different sizes. And the azimuth control ball 3 can swing around the central axis 20 to adjust the angle of the first telescopic cylinder 4. Connect the bolt 22 into the positioning slot 21 to lock the azimuth control ball 3. The operation is simple, further enhancing the flexibility during use;

[0047] During use, align the breathing mask 233 with the mouth and nose, open the manual valve 2310, and make the oxygen in the oxygen storage bag 231 continuously supply oxygen for breathing through the oxygen delivery tube 232 to assist the patient in breathing. The structure is simple and the use is flexible;

[0048] Before use, the oxygen delivery pressure can also be adjusted through the metering component. Initially, an adjusting piston plate 236 and the second orifice plate 238 block the oxygen delivery tube 232. Oxygen can pass through the small holes on the second orifice plate 238. And the small working motor 239 drives the trimming rod 235 to rotate 90 degrees, making the first orifice plate 237 rotate to the original position of the second orifice plate 238. Then, an adjusting piston plate 236 and the first orifice plate 237 block the oxygen delivery tube 232.
