Technical scheme of the present invention is as follows:

A pressure generator, comprising: a sealed container, a solution injection assembly and a gas output assembly arranged on the top of the sealed container, the gas output assembly includes: a first hollow sleeve, sleeved in the first hollow inside the second hollow tube sleeve and the second hollow tube sleeve threaded with it, and the exhalation tube sleeved in the second hollow tube sleeve, one end of the first hollow tube sleeve extends into the sealed container, The other end protrudes out of the sealed container, and the exhalation tube is clamped and sealed with the second hollow tube sleeve, and the second hollow tube sleeve is driven to move along the first hollow tube by rotating the first hollow tube sleeve. The cover moves up and down to prolong or shorten the depth at which the exhalation tube penetrates into the airtight container.

In the above-mentioned pressure generator, a fixed frame is arranged on the top of the sealed container, and the upper end of the first hollow pipe sleeve is restricted on the fixed frame and can rotate relative to the fixed frame.

Said pressure generator, wherein, an annular protrusion is arranged axially around the middle part of the first hollow pipe sleeve, the upper end of the first hollow pipe sleeve is supported on the fixing frame, and the annular protrusion supports Hold on top of airtight container.

A cpap continuous positive airway pressure ventilation system for children, comprising: a ventilator and a humidifier, the outlet of the ventilator is provided with a first connecting tube, and the output of the humidifier is provided with a second connecting tube, the The first connecting tube and the second connecting tube are jointly connected to the breathing end of the patient, and a pressure generator as described in any one of the above is arranged between the ventilator and the first connecting tube.

Beneficial effects of the present invention:

Compared with the prior art, the cpap continuous positive airway pressure system for children and its pressure generator provided by the present invention adopt the threaded cooperation between the first hollow sleeve and the second hollow sleeve, only It is necessary to rotate the first hollow tube cover to drive the second hollow tube cover into the depth of the sealed container, so as to extend or shorten the depth of the exhalation tube extending into the sealed container.

Detailed ways

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 sleeve 331, which is sleeved in the first hollow sleeve 331 and a second hollow sleeve 332 threadedly fitted with it, and sleeved 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, and the exhalation tube 333 and 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 to extend or shorten the The exhalation tube 333 extends into the depth of the airtight container 310 .

When the first hollow tube cover 331 is rotated from the first hollow tube cover 331, the second hollow tube cover 332 threaded with it is forced to rotate, however, the second hollow tube cover 332 is connected with the exhalation tube 333 Clamp fit, and the clamping force of the exhalation tube 333 to the second hollow tube cover 332 is greater than the rotational force applied by the first hollow tube cover 331 to the second hollow tube cover 332, which makes the second hollow tube cover 332 at this time The hollow sleeve 332 does not rotate with the first hollow sleeve 331 , 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 fit in the airtight container 310 has changed, which indirectly changes the air flow rate of the exhalation tube 333. 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, a fixing frame 334 is arranged on the top of the airtight container 310 , 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.
