detailed description

The present invention provides a cpap continuous positive airway pressure system for children and its pressure generator. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

Please refer to Fig. 1, Fig. 1 is the three-dimensional view of the continuous positive airway pressure ventilation system for children cpap of the present invention. The output end is provided with a first connecting pipe 110, and the output end of the humidifier 200 is provided with a second connecting pipe 210. The first connecting pipe 110 and the second connecting pipe 210 are jointly connected to the patient's respiratory end, and also include a The pressure generator 300 between the ventilator 100 and the first connecting tube 110 .

As shown in FIG. 2 and FIG. 3 , FIG. 2 is a perspective view of the pressure generator of the present invention, and FIG. 3 is a cross-sectional view of the pressure generator of the present invention. The pressure generator 300 includes: a sealed container 310 arranged in the sealed container Solution injection assembly 320 and gas output assembly 330 at the top of 310. Specifically, the gas output assembly 330 includes: a first hollow tube sleeve 331, a second hollow tube sleeve 332 sleeved in the first hollow tube sleeve 331 and threadedly matched with it, and a second hollow tube sleeve 332 sleeved in the The exhalation tube 333 in the second hollow tube cover 332, one end of the first hollow tube cover 331 extends into the airtight container 310, and the other end extends out of the airtight container 310, the exhalation tube 333 is connected to the airtight container 310 The second hollow sleeve 332 is clamped and sealed, and the second hollow sleeve 332 is driven to move up and down along the first hollow sleeve 331 by rotating the first hollow sleeve 331, so as to extend or shorten the breathing The air tube 333 protrudes into the depth of the airtight container 310 .

When the first hollow sleeve 331 is rotated from the upper end of the first hollow sleeve 331, the first hollow sleeve 331 exerts a rotational force on the second hollow sleeve 332, however, the second middle The hollow tube cover 332 is clamped with the exhalation tube 333, and the clamping force of the exhalation tube 333 on the second hollow tube cover 332 is greater than the rotation exerted by the first hollow tube cover 331 on the second hollow tube cover 332 Force, which makes the second hollow sleeve 332 not rotate with the first hollow sleeve 331 at this time, but moves up and down along the first hollow sleeve 331. Although the depth of the exhalation tube 333 in the airtight container 310 does not change, the depth of the second hollow tube cover 332 that is clamped and sealingly matched in the airtight container 310 has changed, which indirectly changes the airtightness of the exhalation tube. The depth of the tube 333 inside the sealed container 310 . Through this adjustment method, not only the adjustment accuracy is high, but also the exhalation tube 333 is fixed, which will not cause misoperation, and will not affect the patient's breathing end at the same time.

Further, the top of the airtight container 310 is provided with a fixing frame 334 , and the upper end of the first hollow sleeve 331 is restricted on the fixing frame 334 and can rotate relative to the fixing frame 334 . Specifically, an annular protrusion 335 is axially arranged around the middle of the first hollow sleeve 331 , the upper end of the first hollow sleeve 331 is supported on the fixing frame 334 , and the annular protrusion 335 supports At the top of the sealed container 310 , the first hollow sleeve 331 is restricted on the fixed frame 334 and can rotate relative to the fixed frame 334 to adjust the depth of the exhalation tube 333 protruding into the sealed container 310 .

To sum up, the cpap continuous positive airway pressure system for children and its pressure generator provided by the present invention, because the first hollow sleeve and the second hollow sleeve are threaded, only need to rotate The first hollow sleeve drives the second hollow sleeve to extend into the sealed container, so as to extend or shorten the depth of the exhalation tube inserted into the sealed container.

It should be understood that the application of the present invention is not limited to the above examples, and those skilled in the art can make improvements or transformations according to the above descriptions, and all these improvements and transformations should belong to the protection scope of the appended claims of the present invention.
