Problems solved by technology

[0003] In the prior art, the ultrasonic nebulizer usually simply cooperates with a hose to discharge air. When the patient receives nebulization treatment, the liquid droplets formed after nebulization are easy to flow back into the nebulizer, causing the nebulizer The internal medicinal liquid is turbid, which affects the medicinal effect, and because the amount of mist in the hose is not well controlled, it causes inconvenience to the patient when absorbing the atomized medicinal liquid

Embodiment 1

[0041] Such as Figure 1-7 As shown, a mist outlet device for a medical ultrasonic nebulizer includes a mist outlet tube and a mist outlet nozzle 3, the mist outlet tube includes a check tube 1 and a cooling tube 2, and one end of the check tube 1 is used to communicate with The ultrasonic atomizer is connected, and the other end of the check pipe 1 is connected to the cooling pipe 2, and the check pipe 1 is provided with a plurality of anti-reflux sheets 100 and a circular frustum-shaped anti-reflux pipe 110, and the anti-reflux pipe 1 The diameter of one end of 110 is equal to the diameter of the check pipe 1, and the diameter of the other end of the anti-reflux pipe 110 is smaller than the diameter of the check pipe 1, and the anti-reflux sheet 100 is located above the anti-reflux pipe 110 A plurality of anti-backflow sheets 100 can be combined to form a circle matching the inner diameter of the check pipe 1, and a plurality of rotating shafts 101 are arranged radially insi...

Embodiment 2

[0046] Such as figure 1 and image 3 As shown, this embodiment is based on Embodiment 1. The cooling pipe 2 includes a first pipe body 20 and a second pipe body 22, and the passage between the first pipe body 20 and the second pipe body 22 is spherical. The third pipe body 21 is connected, the first pipe body 20 is connected to the base 30, the second pipe body 22 is connected to the check pipe 1, and a plurality of cooling plates 210 are arranged at intervals in the third pipe body 21 , the cooling plate 210 is provided with a plurality of through holes passing through the upper and lower sides of the cooling plate 210 .

[0047] The mist enters the third pipe body 21 through the second pipe body 22, and the mist passes through the gap between the through hole and each cooling plate 210, and moves upward into the first pipe body 20. During this process, the temperature of the mist is reduced, avoiding the mist temperature. Too high scald people's mouth and esophagus.

Embodiment 3

[0049] Such as Figure 1-2 As shown, in this embodiment, on the basis of Embodiment 1, the end of the oral tube 33 close to the stop plug 310 is provided with a filter cartridge 320, and the filter cartridge 320 is detachably connected to the oral tube 33 .

[0050] The filter cartridge 320 can filter impurities in the mist to prevent the inside of the mist nozzle 3 from being blocked.

Abstract

The invention discloses a medical mist outlet device used for an ultrasonic atomizer. The medical mist outlet device comprises a mist outlet tube and a mist outlet nozzle, the mist outlet tube comprises a non-return tube and a cooling tube, multiple anti-reverse flow pieces and a cone-frustum-shaped anti-reverse flow tube are arranged in the non-return tube, the anti-reverse flow pieces can be combined to form a round matched with the non-return tube in inner diameter, multiple rotating shafts are radically arranged inside a tube branch, and one side of each anti-reverse flow piece sleeves thecorresponding rotating shaft; the mist outlet nozzle comprises a base of a hollow structure, a first cannula, a second cannula and a holding-in-mouth tube, the base is connected with the cooling tube, the holding-in-mouth tube is in threaded connection into the second cannula, the second cannula is in threaded connection in the first cannula, the first cannula is in threaded connection in the base, a mist outlet is formed in the end, close to the base, of the first cannula, and a flowing-stopping piston is arranged in the first cannula. The medical mist outlet device has the advantages of preventing mist from reverse flow and controlling the flow of the mist in unit time.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a mist-discharging device for a medical ultrasonic nebulizer. Background technique [0002] The basic principle of the application of ultrasonic atomization technology in medical treatment is: the oscillating signal from the main circuit board is amplified by the high-power triode and transmitted to the ultrasonic chip. The ultrasonic chip converts the electric energy into ultrasonic energy. Sexual drugs are atomized into tiny mist particles of 1um to 5um, using water as the medium, using ultrasonic directional pressure to spray water-soluble medicinal liquid into a mist shape, with the help of internal fan wind, the medicinal liquid is sprayed into the patient's airway, and then inhaled by the patient. Act directly on the focus, mainly used in internal medicine, surgery, ENT, pediatrics and other aspects. [0003] In the prior art, the ultrasonic nebulizer usually simply cooper...
