Description
Technical field
The present invention relates to medical instruments field more particularly to a kind of inhalation anesthetic electron evaporation devices.
Background technique
Anesthetic is sucked by respiratory tract, is generated central nervous system impression, is made patient's brief loss of consciousness and cause not feel
It is the main method of general anesthesia to having aches and pains all over, the anesthesia depth is related with partial pressure of the drug in brain tissue, works as arcotic
After being metabolized from internal discharge or in vivo, patient is gradually recovered awake, and does not stay any sequelae.Inhalation anesthesia generation in vivo
It thanks, decomposition of little；It is most of to be excreted with original shape from lung, therefore inhalation anesthesia is easy to control, and is compared safely, effectively, is anesthesia
In a kind of common method.
For the safety of patient and medical worker, anesthetic is usually transported in suitable container with liquid.Known liquid
Body anesthetic includes fluothane, isoflurane, Sevoflurane, desflurane, enflurane and methoxyflurane.Liquid anaesthetic agent passes through anesthesia
Vaporising device vaporizes liquid anaesthetic agent, becomes the carrier gas mixing of such as oxygen or nitrogen that patient may be inhaled etc.
Anesthetic dosing process is cumbersome, is easy leakage.Especially desflurane, boiling point are 23 DEG C, at room temperature
Boiling, therefore tradition machinery electronic anesthetic vaporizer cannot be used, it is necessary to use special electron evaporation device, more efficient control anesthetic
Gas output.
Summary of the invention
A kind of inhalation anesthetic electron evaporation device, including liquefied anesthetic measurement and control of temperature unit, anesthetic gases distribution list
Member and safety monitoring unit, it is characterised in that：
The inhalation anesthetic electron evaporation device also has and measures anesthetic liquid level using differential pressure liquid；
The inhalation anesthetic electron evaporation device also has anesthetic gases flow sensor；
The inhalation anesthetic electron evaporation device also has height above sea level meter；
The inhalation anesthetic electron evaporation device, anesthetic concentration adjustment disk can be controlled manually or automatically.
Anesthetic flow sensor is in the anesthetic gas circuit between proportioning valve and code-disc.
Differential pressure levelmeter is realized by the differential pressure that measurement anesthetic liquid bottom and top vaporize position to level gauging.
Anesthetic concentration adjustment disk includes motor and transmission system, has position sensor, monitors code-disc position.
Gas flow after anesthetic vaporizes is calculated by flow sensor, according to the anesthetic latent heat of vaporization, calculates anesthetic
The heat taken away is vaporized, in conjunction with liquid level signal, provides lead compensation parameter to the unit temperature control of liquefied anesthetic measurement and control of temperature.
System can be automatically adjusted according to height above sea level, anesthetic concentration adjustment disk, compensate concentration caused by height above sea level
Variation.
Preferably, differential pressure levelmeter sensor uses monocrystalline silicon or capacitance kind micro-pressure sensor.
Preferably, flow sensor uses thermal type mass flow sensor.
Preferably, automatically controlled code-disc motor uses stepper motor, has two-position sensor.
Preferably, feedforward parameter is introduced according to flow sensor, temperature sensor, liquid level sensor, thermal control mode uses
Pid control mode keeps liquid anaesthetic agent temperature in volatilization device constant.
