Description
Technical field
The present invention relates to technical field of medical instruments.
Background technology
Atomization inspiration treatment respiratory tract disease, it is a kind of important, effective way, it is a kind of way of accurate therapeutic treatment disease, adopt nebulizer that medicinal liquid is entered respiratory tract and pulmonary by the mode sucked, reach the object of noinvasive, topical therapeutic, painless, rapid, effective treatment, also at utmost can avoid systemic complications.
Main two kinds of the principle of the nebulizer used clinically at present, one is ultrasound atomizer, one is jet flow type atomizer, jet flow type atomizer is according to venturi ejector principle, compressed air is utilized to form high velocity air by the tiny mouth of pipe, the negative pressure produced drives liquid to be ejected into together on blockage, splashes towards periphery, make drop become droplet microgranule and spray from escape pipe under high-speed impact.
But there are three kinds of defects in the jet flow type atomizer used clinically at present:
First: during patient expiration, nebulizer air vent, while row pressure, aerofluxus, is discharged atomization medicine, is caused drug waste, and seriously, the curative effect of patient is given a discount for national medical insurance input and patient self economic loss; When air-breathing, Sucked medicine simultaneously, has and the pollutant such as pathogen in air is sucked air flue risk, cause cross infection;
Second: patient oneself can not control Sucked medicine flow velocity, uses inconvenience; Such as when all spitting at any time, a people cannot both spit in time postscript time close nebulizer, cause drug waste, use inconvenience;
3rd: the efficiency and the speed that produce atomization medicine are not good enough, and nebulisation time is long.
Summary of the invention
The present invention is serious in order to solve existing medical vaporizer drug waste, there is the risk pollutant such as pathogen in air being sucked air flue during patient breaths, use inconvenience, the efficiency and the speed that produce atomization medicine are not good enough, the problem that nebulisation time is long, thus a kind of medical vaporizer is provided.
A kind of medical vaporizer of the present invention, comprises atomizing cup, atomizing cup core and atomization lid;
The bottom of atomizing cup is provided with air inlet pipe, and one end of air inlet pipe is provided with nozzle, and nozzle comprises nozzle body and nozzle bore, and nozzle body is cylindricality, and conically, nozzle bore is positioned at nozzle tip center, communicates with air inlet pipe on the top of nozzle body; The top of atomizing cup side is provided with suction nozzle mouth, the junction of suction nozzle mouth and atomizing cup is provided with switch, and by the switch of on-off control suction nozzle mouth and the size of opening, the top of atomizing cup opposite side is provided with pressure release orifice, pressure release orifice is provided with filter membrane, and atomization lid is fixed on atomizing cup;
Atomizing cup core comprises support portion and nozzle casing, the bottom of support portion connects nozzle casing, and atomizing cup core is fixed in atomizing cup, and nozzle casing is cylindrical, the top of nozzle casing is conical, its top has aperture, and nozzle casing is tightly placed in nozzle exterior, and the inwall of nozzle casing is provided with narrow groove, narrow groove forms gas passage, the bottom of nozzle casing is provided with bottom notch, and one end of narrow groove extends to described bottom notch, and the space that the other end and nozzle and the nozzle casing of narrow groove surround is communicated with.
Compared with existing nebulizer, this invention is by by atomizing cup integrally closed, in conjunction with switch and filter membrane, make in therapeutic process, the waste of medicine to be dropped to very low, do not affect normal use simultaneously, can not affect the pressure sucked when the normal discharge, pressure and the switch that comprise atomization medicinal liquid oxygen are closed under normal oxygen pressure flow in atomizing cup, the present invention can not increase the volume of nebulizer.A kind of medical vaporizer of the present invention, filter membrane can discharge pressure too high in nebulizer, and the medicine of atomization can also be stoped to leak, and stops the pollutant in ambient atmos to enter, reduce cross infection risk, improve utilization ratio of drug, greatly reduce the waste of medicine, filter membrane energy waterproof, and can also dismantle and change, low price, realizes suitability for industrialized production, can not increase the burden of patient and national medical insurance input.Narrow groove and bottom notch can ensure that the oxygen entered by air inlet pipe produces high speed when contacting with medicinal liquid, improve nebulization efficiency and atomization speed, shorten nebulisation time, are more easily accepted by patient.The junction of suction nozzle mouth and atomizing cup is provided with switch, by the switch of on-off control suction nozzle mouth and the size of opening, realize the flow of atomization medicine and the free adjustment of flow velocity, patient's one hand can operate, facilitate patient to close nebulizer voluntarily at any time not changing under position prerequisite, save medicine; Patient is spit at any time can closing control switch easily, and medicine of avoiding waste, is easy to operation, facilitates patient.
Nebulizer of the present invention greatly improves utilization ratio of drug, greatly reduce drug waste, avoid national medical insurance and drop into waste, save patient treatment expense, alleviate patient economy burden, greatly improve curative effect, concerning chronic obstructive pulmonary disease, asthmatic patient, if calculated by normal use amount, estimate that a patient saves 57.6 yuan in one day, within 1 year, save about 2.1 ten thousand yuan, within 10 years, save about 210,000 yuan.The present invention is easy to suitability for industrialized production, does not increase manufacturing process difficulty, is more suitable for medical applications.
The present invention is applicable to treat respiratory tract disease.
