An anesthetic metering system includes an anesthetic reservoir (1) having an anesthetic reserve (2), which is limited by a flexible material wall and to which pressure is admitted by means of a propellant (3) acting thereon via the wall material. The anesthetic reservoir (1) has a first valve (4), which is in flow connection with the liquid anesthetic reserve (2) and can be inserted into a mounting element (6) of an anesthesia apparatus. The metered release of anesthetic to the anesthesia apparatus takes place via a volumetric nozzle (8). The present invention provides an anesthetic metering device which avoids, on the one hand, the drawbacks of the anesthetic evaporators used previously, which are to be refilled with anesthetics at the workplace, and makes possible the refilling of the anesthetic reservoir (1) at the anesthetic manufacturer, on the other hand.

A system for the delivery of a liquid anesthetic agent to a sump of an anesthetic vaporizer includes a filler assembly rotatable about a pivot point. The filler assembly further includes a sump valve that controls fluid communication between the filler assembly and the sump.

The invention relates to an anesthesia respirator evaporation device. The problems are effectively solved that drawdown of liquid levels of current anesthesia evaporators influences evaporation speed,the evaporation speed and the amount of carried gas cannot be matched and adjusted, and the evaporation speed is low. According to the technical scheme, the anesthesia respirator evaporation device includes an evaporation chamber, multiple layers of evaporating dishes are arranged inside the evaporation chamber, a drug storage cavity is formed above the evaporation chamber, a vertical pipe whichpenetrates through the evaporating dishes in sequence is installed inside the evaporation chamber, the upper end of the vertical pipe is communicated with the bottom of the drug storage cavity, a plurality of plungers which are in one-to-one correspondence to the evaporating dishes and capable of moving up and down are installed inside the vertical pipe, and the plungers move up and down and thencan control whether or not medical liquid is stored inside the corresponding evaporating dishes. The liquid level of the anesthesia respirator evaporation device is constant; according to the amount of the carried gas, the working conditions of the evaporating dishes on each layer can be selectively started and closed, so that the evaporation efficiency of the medical liquid inside the evaporationchamber is matched with the amount of the carried gas; the space utilization rate of the evaporation chamber is high, and the anesthesia respirator evaporation device is compact in structure, small in size and high in evaporation speed.

The invention discloses a temperature-sensing valve with the flow compensation function, which comprises a saddle and a movable plate; an airflow gap allowing airflow to pass through is formed between the saddle and the movable plate; an air hole cavity is formed inside the saddle, and is communicated with the airflow gap; when the flow at a fresh air inlet increases, the airflow gap becomes small to cause the flow of fresh air flowing into the temperature-sensing valve to decrease; when the flow at the fresh air inlet decreases, the airflow gap becomes large to cause the flow of the fresh air flowing into the temperature-sensing valve to increase; and the temperature-sensing valve has the advantage of simple structure, and is easy to process and convenient to dismantle. The invention further discloses an anesthetic vaporizer which comprises the temperature-sensing valve, a curved pipe box, the fresh air inlet and a mixed gas outlet; the fresh air inlet is communicated with the inlet of the temperature-sensing valve; an outlet of the temperature-sensing valve is communicated with the mixed gas outlet; and the anesthetic vaporizer can ensure that the concentration of the output gas is not changed along with the variation of flow at the fresh air inlet, that is, the concentration of the output gas keeps consistent with the set valve.

An anesthetic vaporizer and a temperature compensation unit are disclosed. The temperature compensation unit, which cooperates with a vaporizing chamber having a bottom wall, includes a first device connected to the bottom wall of the vaporizing chamber for contacting with liquid anesthetic agent in the vaporizing chamber and changing in length according to temperature change of the liquid anesthetic agent, and a second device connected to the vaporizing chamber. A gas flow gap through which a gas flow passes is formed between the first and second devices. The gas flow gap becomes larger as temperature of the liquid anesthetic agent rises and smaller as the temperature of the liquid anesthetic agent drops. Since the first device is connected with the bottom wall of the vaporizing chamber, the first device will directly contact with the liquid anesthetic agent regardless of the liquid level of the anesthetic agent, as long as there is liquid agent in the vaporizing chamber; therefore the efficiency of heat exchange is high and the effect of temperature compensation is good.
