Embodiment Construction

[0031] Such as Figure 5 As shown, in this embodiment, the temperature control valve with flow compensation function of the present invention includes a seat block 31 and a movable plate 32, which form an air flow gap for air flow through each other, and the seat block 31 has gas inside. The cavity 311, the gas cavity 311 communicates with the airflow gap.

[0032] On the front of the seat block 31, a groove for mounting the movable plate 32 is opened, and the movable plate 32 is embedded in the groove. The joint surface of the movable plate 32 and the seat block 31 forms an airflow gap.

[0033] One end of the seat block 31 and the movable plate 32 is fastened by the screw 4, and the other end is compressed by the spring sheet 33. On the outside of the spring sheet 33, an upper backing plate 34 and a lower backing plate are respectively provided corresponding to the movable plate 32 and the seat block 31 35. A spring pressure plate 36 is arranged outside the lower backing plate 35...

Abstract

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.

Description

Technical field [0001] The invention relates to the field of anesthesia machines, in particular to a temperature control valve with a flow compensation function and an anesthesia vaporizer containing the same. Background technique [0002] The evaporator is an important part of the anesthesia machine, which can effectively evaporate the anesthetic liquid, produce an anesthetic vaporized gas, mix with fresh gas, and accurately input the anesthesia breathing circuit according to the concentration set by the anesthesiologist, and then output to the patient. [0003] In practical applications, fresh gas enters the evaporator, and the gas is divided into two paths. One is called carrier gas, which enters the anesthetic evaporation chamber, which can effectively carry out the anesthetic evaporation gas, and the other is called bypass gas, which passes through the temperature control valve. , And then the two gases are mixed into anesthetic gas and output to the patient. Modern anesthesi...
