Description

A kind of with breathing synchronous medical vaporizer

Technical field the present invention relates to a kind of ultrasound atomizer of medical instruments field.

No. 871049821 Chinese patent of background technology discloses a kind of quasi synchronous ultrasound atomizer, atomization circuit is worked at interval, and can adjust its working cycle and gap periods, wish to make patient's breathing synchronous with the working condition maintenance of nebulizer, patient inhales when being atomization circuit work medical liquid atomizing, patient respiration when atomization circuit quits work reaches medicine and the energy-conservation effect of saving.But in actual use, because people's breathing is stablized constant unlike machinery, change and exist, such as running into extraneous interference, the perhaps variation of patient's emotion, the capital causes the variation of breath rhythm, cause the gap periods of breathing asynchronous, or not during this work, or not when this stops with the ultrasonic atomizatio circuit, lose this technology fully and wish the effect that reaches, even cause reverse effect.And to allow patient notice constantly whether the breathing of oneself changes, and observe the working condition of atomization circuit constantly, or constantly control the work of nebulizer by hand, both bothered also unrealistic, more can cause patient's spirit in tension, be unfavorable for health.

Summary of the invention the present invention seeks to the medical vaporizer of open a kind of like this interval work, and it can more easily make the working cycle of atomization circuit synchronous accurately with patient's breath rhythm maintenance.

Nebulizer of the present invention comprises atomization circuit, it is characterized in that: nebulizer also includes one can send the breath prompting device of breathing prompt tone; Breath prompting device is by breath rhythm generating circuit and constituted by the respiratory murmur generation circuit that includes sounding component of breath rhythm generating circuit control; Breath rhythm generating circuit connects and controls the work of atomization circuit simultaneously.

Described breath rhythm generating circuit, the output of the breath rhythm of generation include inspiratory cycle T1, exhalation cycle T2 and gap periods T3.These three cycles can be regulated by the variable resistance of breath rhythm generating circuit.Rhythm generating circuit control atomization circuit carries out work at inspiratory cycle, and quits work in exhalation cycle and gap periods.Described respiratory murmur generating means sends air-breathing prompt tone at inspiratory cycle, sends the expiration prompt tone in exhalation cycle.

During use, the user adjusts breath rhythm generating circuit, and air-breathing prompt tone and expiration prompt tone that the respiratory murmur generating means is sent are synchronous with the breathing maintenance of oneself, just can normally use.At this moment breath rhythm generating circuit is being controlled the work of atomization circuit, make atomization circuit keep with the user breathe synchronously, reach saving medicine and purpose of energy saving.Its meaning is, cause respiratory variations even in use run into external interference or patient's emotion changes, cause the gap periods of breathing asynchronous with nebulizer, patient is closing eyes just can hear the breathing prompt tone at any time, again keep synchronous so can adjust the breathing of oneself at an easy rate with the breathing cue, also being patient also can make the breathing of oneself and the interval working cycle of nebulizer keep synchronous accurately in reposing closing one's eyes, and reaches real synchronous effect.And stable breathing prompt tone can keep stable and tranquil in the breathing of inducing patient virtually, helps loosening patient's spirit, plays the effect that promotes treatment.Particularly use nebulizer mostly to be asthma patient, stable tranquil breathing is highly significant to mitigate the disease.

As improvement, send the time of air-breathing prompt tone, delay a buffer circle T4 than inspiratory cycle.Buffer circle mainly is to consider that medicinal liquid is atomised to flow to by conduit from nebulizer to need certain slack time between the breathing mask, just corresponding this slack time of buffer circle T4, just send air-breathing prompt tone when making medicine mist after the atomizing deliver to breathing mask, realize synchronous more accurately.Further improve, air-breathing prompt tone and expiration prompt tone all have gradually big gradually little effect, make the user sound more custom.

Description of drawings Fig. 1 is a functional-block diagram of the present invention.Fig. 2 is the sequential sketch map in each cycle.

With reference to the accompanying drawings the present invention is narrated below the specific embodiment:

Among Fig. 1, atomization circuit belongs to prior art, even medicinal liquid produces the interlock circuit of atomizing.Nebulizer of the present invention also includes one can send the breath prompting device of breathing prompt tone; Breath prompting device is by breath rhythm generating circuit and constituted by the respiratory murmur generation circuit that includes sounding component of breath rhythm generating circuit control; Breath rhythm generating circuit connects and controls the work of atomization circuit simultaneously.

Breath rhythm generating circuit is used for producing with the similar breath rhythm signal of human body respiration, the output of the breath rhythm that produces includes the gap periods T3 between inspiratory cycle T1, exhalation cycle T2 and the inspiratory cycle connection exhalation cycle, as the waveform of transverse axis S1 among Fig. 2.Breath rhythm generation circuit can adopt time base circuit to realize, also can adopt single-chip microcomputer is that microprocessor MCU realizes, come the cycle of T1, T2, T3 is regulated by W1, W2, three variable resistances of W3, the ordinary skill that this belongs to the easy realization of electronic technology field is not described in detail here.

The output of rhythm generating circuit is connected with respiratory murmur and produces circuit, and respiratory murmur produces circuit and includes sounding component such as loudspeaker, can produce the breathing prompt tone, and be subjected to the control of the output signal of rhythm generating circuit.Send air-breathing prompt tone at inspiratory cycle T1, the sound such as similar " inhale～～～～" sends the expiration prompt tone at exhalation cycle T2, such as the sound of similar " exhale～～～～", at gap periods sounding not.Shown in the figure of the transverse axis S3 among Fig. 2.Respiratory murmur produces circuit can adopt audio oscillator circuit or chip microcontroller, and to breathe prompt tone vivider in order to make, and also can adopt the dedicated voice circuit, synthetic or record people's breathing sound.

The work of atomization circuit is controlled in the output of rhythm generating circuit simultaneously, makes atomization circuit only carry out work at inspiratory cycle T1, and quits work in exhalation cycle and gap periods.Shown in the figure of transverse axis S2 among Fig. 2.Control mode can adopt relay or power switch pipe control, for the atomization circuit that adopts ultrasonic oscillating circuit, can directly control the base stage of concussion pipe, make oscillating circuit only normally shake work at inspiratory cycle T1, produce atomizing, and stop concussion in T2, T3 cycle, nebulizer is not worked.

Like this, the work that the output control breathing sound of rhythm generating circuit produces circuit produces the breathing prompt tone, induce patient that the breathing of oneself is kept synchronously with prompt tone, the work of the atomization circuit of rhythm generating circuit control simultaneously, atomization circuit is only atomized in the cycle in patient inhales, and do not work at other times, reach the purpose of energy saving of saving medicinal liquid, and help patient and keep breathing tranquil and stable.

As improvement, respiratory murmur produces the time that circuit sends air-breathing prompt tone, delays a buffer circle T4 than inspiratory cycle T1.Shown in the figure of the transverse axis S4 of Fig. 2.Buffer circle T4 considers that medicinal liquid is atomised to flow to by conduit from nebulizer to need certain slack time between the breathing mask, just corresponding this slack time of buffer circle T4, atomization circuit was started working in the T1 cycle produce the medicine mist, when the medicine mist is delivered to breathing mask under the fan effect, just send air-breathing prompt tone, when residue medicine mist was sent to breathing mask after atomization circuit quits work, prompt tone just stopped suction.Realize synchronous more accurately and saving medicinal liquid effect.

Further improve, air-breathing prompt tone and expiration prompt tone all have gradually big gradually little effect.Shown in the figure of Fig. 2 transverse axis S5.Patient sounds more melodious and custom like this, and it is tranquil to help patient's spirit.
