Description
Technical field
The present invention relates to field of medical device, is breathed more specifically to a kind of compatible ascending manner and descending manner bellows
The anesthesiaing system in circuit.
Background technology
In anesthesia machine system scheme, with patient end it is nearest be breathing circuit, its major function and effect is：For machine
Tool is ventilated or manual ventilation provides a closed respiration channel, after the CO2 gases in patient's exhaled gas is absorbed by soda lime
Anesthetic gases in exhaled gas can repeat to suck by patient；Meanwhile breathing circuit also realizes tidal volume, airway pressure and oxygen
The monitoring of concentration.
On world market, country variant or region are different to the hobby of bellows, and some countries and regions are got used to making
With the breathing circuit of ascending manner bellows, and some countries and regions then get used to the breathing circuit using descending manner bellows.
By taking ascending manner bellows as an example, as shown in figure 9, the operation principle of bellows device is as follows in breathing circuit：
Expiratory phase, the gas (CO2 gases and anesthetic gases) of patient's exhalation enter in the folding capsule in bellows device；Air-breathing
Phase, drives the folding capsule 01 in gas compression bellows, and the gas press-in CO2 absorbers in folding capsule 01 are disposed CO2 gases
Patient lung is transported to together with live gas afterwards to be absorbed.In Anesthesia machine normal work, when corresponding to expiratory phase, Bing Renhu
The gas gone out, which can enter, to be folded in capsule 01 and rises to the top of bellows cover 02, and unnecessary gas is then from the POP- in bellows device
Discharge and then via being emitted after AGSS at OFF valves 03.
The user of selection ascending manner bellows breathing circuit thinks：Observe by the naked eye rise bellows in fold capsule 01 whether on
Anesthesia machine can intuitively be judged with the presence or absence of leakage very much by being raised to the top of bellows, if bellows cannot be risen to by folding capsule 01
Then there is leakage in machine at top, and user get used to identify machine with the presence or absence of leakage with this method.
And the user of descending manner bellows breathing circuit is selected then to think：1) if the machine of ascending manner bellows breathing circuit is deposited
In leakage, it is necessary to the folding Nang Chong collapsed be expired the top until rising to bellows by quick oxygenate apparatus；This can lead
The oxygen dilution for causing the anesthesia gas concentration in breathing circuit to be quickly filled with rapidly, i.e. anesthetic concentration are decreased obviously, and influence fiber crops
Liquor-saturated effect, system need to can be only achieved by one long time before anesthetic concentration.And descending manner bellows breathing circuit is such as
It need not be then oxygenated when fruit has leakage by quick, because the folding capsule in descending manner bellows breathing circuit can be downward under its own weight
Reach the bottom of bellows.Then there is no the situation that anesthesia gas concentration is diluted.2) ascending manner bellows circuit can produce one admittedly
Some PEEP values (end-expiratory positive pressure), the PEEP values be generally 2cmH2O and more than；And the PEEP of descending manner bellows breathing circuit
(end-expiratory positive pressure) can accomplish to be zero, there is important clinical application significance.

In order to control the gas flow when patient breathes out and sucks, absorption unit of dioxide carbon 226 and expiration pipeline 222
Connecting node prevent what gas from circulating to 223 side of expiratory flow sensor to being provided between expiratory flow sensor 223
Expiratory one-way valve.The connecting node of absorption unit of dioxide carbon 226 and live gas pipeline 224 is to inspiratory flow sensor 225
Between be provided with the breather cheek valve for preventing that gas from circulating to 226 side of absorption unit of dioxide carbon.When patient breathes out, exhalation
Gas can only flow to ascending air bladder.In patient's air-breathing, the gas in ascending air bladder is removed through absorption unit of dioxide carbon 226
Pneumostome 2212 is flowed to together and is inhaled by a patient with live gas after carbon dioxide, allows the Anesthesia machine breathed out before to suck disease again
In human body, remain unchanged anesthesia amount.
Further, absorption unit of dioxide carbon 226 include the first by-passing valve 2261, soda lime tourie 2262 and
Second by-passing valve 2263.First by-passing valve 2261 includes the first station, second station, and the second by-passing valve 2263 includes the 3rd work
Position, the 4th station, soda lime tourie 2262 are connected with the first by-passing valve 2261, the second by-passing valve 2263 respectively, the first bypass
Valve 2261 is connected with expiration pipeline 222, and the second by-passing valve 2263 is connected with live gas pipeline 224.
At the first operating position, the first by-passing valve 2261 is located at first for first by-passing valve 2261, the second by-passing valve 2263
Station, the second by-passing valve 2263 are located at 3rd station so that expiration pipeline 222, the first by-passing valve 2261, soda lime tourie
2262nd, the second by-passing valve 2263 and live gas pipeline 224 are sequentially communicated, and allow ascending air bladder gas therein when being compressed
Carbon dioxide absorption can be fallen after soda lime tourie 2262.First by-passing valve 2261, the second by-passing valve 2263 are second
During operating position, the first by-passing valve 2261 is located at second station, and the second by-passing valve 2263 is located at the 4th station, the first by-passing valve
2261st, the second by-passing valve 2263 mutually separates, and prevents the gas mixing between expiration pipeline 222, live gas pipeline 224, keeps away
The amount of anesthetic after the gas outflow for exempting from originally to breathe out to sucking again impacts.
First bellows host 22 further includes machine control/manual ventilation selecting switch 227, Manual bladder 2281, adjustable pressure
Valve 2282 is limited, machine control/manual ventilation selecting switch 227 is arranged on the company of absorption unit of dioxide carbon 226 and expiration pipeline 222
Connect node upstream.

222 gas circulation styles.Manual bladder 2281 is equivalent to ascending air bladder, decline air bag, for storing and outwardly against exhalation
Gas.
When machine control/manual ventilation selecting switch 227 is located at machine control operating position, the expiration pipeline of the first bellows host 22
222 conductings, manual exhaust pipeline 228 are disconnected with expiration pipeline 222, and exhalation is fed directly to rising to 222 gas of expiration pipeline
Air bag, controls the flowing of gas by the way of machine control.
When machine control/manual ventilation selecting switch 227 is located at manual work position, the expiration pipeline of the first bellows host 22
222 disconnect, and manual exhaust pipeline 228 is turned on expiration pipeline 222, and exhalation to 222 gas of expiration pipeline flows into dynamic leather bag in one's hands
2281, adopt the flowing for manually controlling gas.When patient exhales, the gas with anesthetic of patient's exhalation enters
Into Manual bladder 2281, Manual bladder 2281 is filled.Excessive gas can then be released by adjustable pressure limit valve 2282
Remaining anesthetic gases recovery system is put into be absorbed.In patient's air-breathing, then Manual bladder 2281 is pinched by the inside by receiving
Gas is pressed into soda lime tourie 2262 and sponges carbon dioxide, is transported to after then merging with live gas in disease population.
Second adapter assembly 12 includes manual exhaust anesthesia side interface 126；Manual exhaust bellows side interface 2217 with manually
Exhaust anesthesia 126 corresponding matching of side interface, realizes that gas is discharged manually, and the excessive gas of exhalation is anaesthetized gas by remnants
Body recovery system is absorbed.
Since the structure of the first bellows host 22, the second bellows host 32 is identical, internal component forms identical, descending manner
30 and its second bellows host 32 of bellows breathing circuit and anesthesia host 10 between cooperation and operation principle also with ascending manner wind
