Description
Technical field
The utility model relates to Anesthesia machine, TCI anesthesia machine in especially a kind of inhalation anesthetic breathing circuit.
Background technique
Anesthesia machine is mainly made of anesthesia respirator, corrugated hose, inhalation anesthetic high-precision evaporator and auxiliary device,
Anesthesia machine is connected to form a circuit with patients with respiratory tract by corrugated hose gas delivery port transtracheal intubation, and referred to as anesthesia is exhaled
Suck back road.
In operation, patient does not have autonomous respiration, and anesthesia respirator row mechanical ventilation is needed to substitute patient respiratory.In anesthesia respiration
The intake period of machine row mechanical ventilation, Anesthesia machine by breathing circuit for anesthesia by live gas and inhalation anesthetic through check valve, exhale
Suction pipe road gas delivery port is transported in patients with respiratory tract；The expiration phase of mechanical ventilation, the gas of patient's exhalation, through corrugated hose
Gas delivery port excretes, and by another check valve, comes back in Anesthesia machine.Continue due to perseverance because containing in Anesthesia machine
The supplement of fixed live gas, the portion gas of patient's exhalation are discharged anesthesia respiration in the form of waste gas of anesthesia through outlet port and returned
Road；Because containing a certain concentration carbon dioxide, the another part gas of patient's exhalation need to pass through absorption unit of dioxide carbon for dioxy
Change carbon absorption removal, then mixed with the live gas supplemented in Anesthesia machine, completion respiration recycles and enters to be breathed next time
Circulation.
Existing Anesthesia machine suffers from the drawback that 1, can not count due to using inhalation anesthetic high-precision evaporator
Inhalation anesthetic usage amount；2, the ramp-up rate of drug concentration is slow within the Inhalation anesthesia induction stage, breathing circuit, reaches pre-
It is long to determine the depth of anesthesia time, and inhalation anesthetic drug concentration is understable for a long time in breathing circuit for anesthesia；3, it is applied to clinic
The inhalation anesthetic of anesthesia is many kinds of, need to use different evaporators using different inhalation anesthetics；4, it is lured in inhalation anesthesia
The stage is led, in order to accelerate the ramp-up rate of drug concentration in breathing circuit, is often used increasing " live gas containing inhalation anesthetic "
Flow and the mode for improving inhalation anesthetic drug concentration, cause the waste of inhalation anesthetic.
Summary of the invention
The purpose of this utility model be just to provide it is a kind of can accurately count inhalation anesthetic usage amount, be conducive to keep constant
Depth of anesthesia, and meet a variety of inhalation anesthetics and be used in conjunction with, while saving the inhalation anesthetic of inhalation anesthetic usage amount
TCI anesthesia machine in breathing circuit.
TCI anesthesia machine in the inhalation anesthetic breathing circuit of the utility model, including absorption unit of dioxide carbon, gas
Cannula, air storage bag, gas transmission supervisor, anesthesia respirator, which is characterized in that the outlet of target controlled infusion pump is connected with gas transmission supervisor
It is logical；Anesthesia respirator, air storage bag are connected with gas transmission supervisor；The inlet end of gas transmission supervisor is divided to two branches, and a branch passes through
Gate valve is connect with oxygen intake end, and another branch is connected by check valve, flowmeter, gate valve with oxygen intake end；Gas transmission supervisor
Outlet side through breather cheek valve, threeway and trachea cannula connect, trachea cannula access patients with respiratory tract, threeway the other end warp
Expiratory one-way valve connects absorption unit of dioxide carbon, is arranged APL pressure limiting valve on absorption unit of dioxide carbon, absorption unit of dioxide carbon simultaneously with
Gas transmission supervisor's connection.
TCI anesthesia machine in the inhalation anesthetic breathing circuit of the utility model pumps substitution sucking by target controlled infusion
Arcotic high-precision evaporator, makes target controlled infusion in inhalation anesthetic corrugated hose, can accurately count inhalation anesthetic usage amount,
Continuous constant spray pattern is accommodated using single metered injection, liquid inhalation anesthetic infusion is directly entered into breathing circuit for anesthesia,
Inhalation anesthetic is gasificated into anesthetic gases in breathing circuit for anesthesia, breaks gas exchanges time constant concept, in corrugated hose
Inhalation Anesthetic concentration can be increased quickly, sucking anesthetic concentration is rapidly reached effective anesthetic concentration in alveolar, and be breathed
Inhalation Anesthetic concentration is stablized in pipeline, and the vital sign that the liquor-saturated depth degree ﹑ of fiber crops for being conducive to keep constant maintains patient stable mentions
High quality of anesthesia；And it is able to achieve the clinical demand that a device meets a variety of inhalation anesthetics, sucking is saved to a certain extent
The usage amount of arcotic.
