Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.

As shown in fig. 1 to 6, the present application provides an anesthesia machine, including an anesthesia machine main body, a gas transmission device 30 and a driving system 20, wherein the gas transmission device 30 and the driving system 20 are both disposed on the anesthesia machine main body, and the driving system 20 is used for driving the gas transmission device 30, so that the gas transmission device 30 can provide airflow for a patient.

Illustratively, anesthesia machines are devices that are primarily used to provide oxygen, anesthesia, and respiratory support to a patient during surgery, with modes of operation including manual and mechanically controlled modes. The manual mode is mainly used for supplying air to a patient in a manual leather bag pinching mode in an induction stage immediately after operation and a resuscitation stage after operation, and the mechanical mode is used for realizing ventilation control through an inhalation valve and an exhalation valve in an operation process.

Specifically, in the mechanically controlled mode, when the patient exhales, the gas exhaled by the patient enters the gas delivery device 30 along the breathing line and is stored; when the patient inhales, the driving system 20 controls the driving gas with certain flow rate and pressure to enter the gas delivery device 30, and pushes the gas in the gas delivery device 30 to provide the gas for the patient, and after the gas is absorbed by the absorption device, the gas is mixed with fresh gas carrying anesthetic gas and oxygen after carbon dioxide is removed, and enters the lung of the patient, so that one respiratory cycle is completed.

In an alternative embodiment, the gas delivery device 30 is a bellows assembly in which a folded bladder is capable of storing a quantity of gas containing a gunpowder component upon transition between inhalation and exhalation by a patient. Specifically, when the patient exhales, the gas exhaled by the patient enters the folding bag along the breathing pipeline and lifts up the folding bag. When the patient inhales, the driving system 20 controls the driving gas with certain flow rate and pressure to enter the bellows, the driving gas pushes the folding bag to move downwards, the gas in the folding bag is further pressed out, the gas flows through the carbon dioxide absorbing tank so as to filter carbon dioxide, and then the gas is mixed with fresh gas carrying anesthetic gas and oxygen and enters the lung of the patient, so that one respiratory cycle is completed.

In an alternative embodiment, the gas delivery device 30 is a volume reflector, and the gas exhaled by the patient enters the volume reflector along the breathing circuit and is stored while the volume reflector is capable of expelling excess gas. When the patient inhales, the driving system 20 controls the driving gas with certain flow rate and pressure to enter the volume reflector and pushes the gas in the volume reflector, so that the gas in the volume reflector is pushed out, flows through the carbon dioxide absorbing tank so as to filter carbon dioxide, and then enters the lung of the patient after being mixed with fresh gas carrying anesthetic gas and oxygen, so that one respiratory cycle is completed.

The driving system 20 is a pneumatic driving system 21 or an electric driving system 22, and the two driving systems 20 have different advantages in use and have very large differences. However, the anesthesia machine of the same model cannot be compatible with the interchange of the two driving systems 20, or only the pneumatic control driving system 21 or only the electric control driving system 22, and the anesthesia machine cannot support the interchange of the two driving systems 20.

In this embodiment, the anesthesia machine further comprises a relay structure 10, wherein the relay structure 10 comprises a driving air inlet 121, an exhalation valve inlet 122 and an exhalation valve outlet 123, and the driving air inlet 121, the exhalation valve inlet 122 and the exhalation valve outlet 123 are located on the same side of the relay structure 10 and are arranged towards the driving system 20 so as to be connectable to the pneumatic or electric control driving system 21, 22.

Specifically, the arrangement of the inhalation channel outlet 20a, the exhalation channel inlet 20b and the exhalation channel outlet 20c on the pneumatic control driving system 21 is the same as the arrangement of the inhalation channel outlet 20a, the exhalation channel inlet 20b and the exhalation channel outlet 20c on the electric control driving system 22, so that the rotary structure 10 can be directly inserted into the inhalation channel outlet 20a, the exhalation channel inlet 20b and the exhalation channel outlet 20c on the pneumatic control driving system 21 or the electric control driving system 22, intermediate connecting pipes are reduced, and the integral disassembly and assembly of the whole machine during assembly are supported.

The transfer structure 10 mainly performs transfer between the gas delivery device 30 and the driving system 20 (the pneumatic control driving system 21 or the electric control driving system 22), so that the anesthesia machine of one type can conveniently realize the exchange of the two different driving systems 20, namely the pneumatic control driving system 21 or the electric control driving system 22, and the economic cost caused by the design change of the anesthesia machine for adapting to the different driving systems 20 is reduced.

In an alternative embodiment, the transfer structure 10 is further provided with an exhale inlet 112 and a drive gas outlet 111, wherein the exhale inlet 112 and the drive gas outlet 111 are located on the same side of the transfer structure 10 and are located towards one side of the gas delivery device 30 for connection with the gas delivery device 30, so that the gas delivery device 30 can communicate with the drive system 20 through the transfer structure 10, so that the drive system 20 can control a certain flow rate and pressure of drive gas into the volume reflector and push the gas in the gas delivery device 30 to provide a gas output for the patient.

In an alternative embodiment, the transfer structure 10 is further provided with an APL exhaust port 113 on the same side as the exhalation inlet 112 or the drive gas outlet 111, the APL exhaust port 113 being adapted to be connected to an APL valve in the anesthesia machine body such that gas exhausted from the APL valve can be exhausted from the APL exhaust port 113, and the gas pressure of the breathing system in the anesthesia machine is controlled in a manual mode so that the patient inhalation gas pressure can be regulated by the APL valve.

For example, when the anesthesia machine is in the manual mode, the gas discharged from the APL valve enters from the APL exhaust port 113 and is discharged through the exhaust gas discharge pipe 13, so that the pressure regulation of the respiratory system in the manual mode is realized.

In an alternative embodiment, as shown in fig. 6, the transfer structure 10 further includes a first pipeline 119 having an exhaust gas outlet 118, the first pipeline 119 being in communication with the APL exhaust interface 113, the exhalation valve outlet 123, and the exhaust gas outlet 13; wherein, the first pipeline 119 is provided with a negative pressure valve 15, and a valve outlet of the negative pressure valve 15 is communicated with the first pipeline 119 and used for balancing the internal pressure in the first pipeline 119.

At this time, the negative pressure valve 15 is opened, and external air is introduced into the first pipeline 119 to balance the pressure inside the anesthesia machine main body, thereby preventing the damage of internal devices due to the excessively high negative pressure of the internal pipeline of the anesthesia machine main body.

Wherein, the gas transmission device discharges redundant gas and discharges the gas into the anesthetic gas purification system; alternatively, if there is excess exhalation air when the collapsible bag is deployed to the extreme position, the bellows assembly may exhaust the excess exhalation air to the anesthetic gas purge system.

In an alternative embodiment, the negative pressure valve 15 further includes a first sealing member 154, the first sealing member 154 being disposed between an outer circumferential wall of the negative pressure valve 15 and an inner circumferential wall of the valve body mounting groove 1192 for filling a gap between the negative pressure valve 15 and the valve body mounting groove 1192 to ensure tightness between the negative pressure valve 15 and the first pipe 119.
