The oxygen supply unit is also used to dilute the anesthetic.

[0008] Wherein, the anesthesia device also includes a breathing assistance unit, which is connected to the medicine feeding component and is used to assist the living being in breathing.

[0009] Wherein, the anesthesia device also includes a pressure gauge, which is respectively connected to the dosing unit, the medicine feeding component and the oxygen supply unit, and is used to detect the pressure between the dosing unit and the medicine feeding component and the pressure between the oxygen supply unit and the medicine feeding component.

[0010] Among them, the oxygen supply unit also includes a second supply port, which is connected to the medicine feeding component and is used to directly deliver oxygen to the living organism to revive the living organism; the pressure gauge is also connected to the second supply port and the medicine feeding component, and the pressure gauge is also used to detect the pressure between the second supply port and the medicine feeding component.

[0011] Wherein, the anesthesia device also includes a recycling component, which is connected to the medicine feeding component. The recycling component is used to purify the gas exhaled by the living organism and then feed it to the living organism again through the medicine feeding component.

[0012] Wherein, the recycling component comprises:

[0013] a collection unit, used for collecting gas exhaled by the living being; and

[0014] A purification unit is connected to the collection unit and is used to purify the gas; the purification unit is also used to connect to the medicine feeding component and is used to feed the purified gas to the living body again.

[0019] The anesthesia device of the embodiment of the present application is to make the living body inhale a mixed gas of anesthetic and oxygen during the breathing process of the living body, wherein most of the anesthetic enters the alveoli, and a small part is exhaled, and then the exhaled gas of the living body is controlled to enter a circuit including a CO2 absorption device, and the circuit removes the CO2 of the exhaled gas and is inhaled again by the living body together with the new mixed gas, thereby ensuring the high utilization rate of the anesthetic. After the anesthetic enters the alveoli of the living body, it diffuses into the blood and directly inhibits the central nervous system, thereby producing the effect of general anesthesia. This inhalation anesthesia method can greatly reduce the chronic damage and impact on the living body. When the anesthesia device described in the present application is used to anesthetize small living bodies (mice, rabbits, cats, etc.), the anesthetic demand for small living bodies is extremely low. The proportion of anesthetic in the mixed gas introduced into the alveoli of the small living body is very low, and the content of unabsorbed anesthetic in the gas exhaled by the small living body is very small, so the exhaled gas can be directly discharged from the anesthesia device to avoid unnecessary consumption of CO2 absorbent. The anesthesia device provided by the present application can control the dosage of the life body, which is convenient for administration and will not cause harm to the life body.

Mentioning "embodiment" or "implementation method" in this article means that the specific features, structures or characteristics described in conjunction with the embodiment or implementation method may be included in at least one embodiment of the present application. The appearance of this phrase at various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0029] Please refer to Figures 1 to 3 The present application provides an anesthesia device 100, which includes a medicine feeding component 150 for feeding anesthetics to a living being (such as an animal); a drug administration unit 120, which includes an air inlet 1211 and an air outlet 1221, and the air outlet 1221 of the drug administration unit 120 is connected to the medicine feeding component 150, and the drug administration unit 120 is used to provide a preset dose of anesthetics to anesthetize the living being; and an oxygen supply unit 110, which includes a first supply port 111, and the first supply port 111 is connected to the air inlet 1211 of the drug administration unit 120, and is used to provide oxygen, and the anesthetic generated by the drug administration unit 120 is delivered to the medicine feeding component 150 to be fed to the living being, and the oxygen supply unit 110 is also used to dilute the anesthetic.

[0030] The anesthesia device 100 of the embodiment of the present application includes a medicine feeding component 150, a drug administration unit 120, and an oxygen supply unit 110. The dosage of the anesthetic fed to the living body can be better quantified through the drug administration unit 120, and the anesthetic can be well delivered to the medicine feeding component 150 to be fed to the living body through the oxygen supply unit 110. The oxygen supply unit 110 is also used to dilute the anesthetic. Therefore, the dosage and concentration of the drug administered to the living body can be better controlled, the drug administration is convenient, and no harm is caused to the living body.

[0031] Optionally, the carrier of the anesthetic is oxygen, which can ensure that the living organism absorbs sufficient oxygen during the anesthesia process to ensure biological activity. Moreover, the amount of anesthetic absorbed by the living organism with each breath is limited. Absorbing a large amount of anesthetic in a short period of time can easily cause life-threatening danger. Oxygen can dilute the concentration of anesthetic absorbed by the living organism and ensure the safety of the living organism.

[0032] Optionally, the medicine feeding component 150 includes a first medicine feeding unit 151 and a second medicine feeding unit 152, and the first medicine feeding unit 151 and the second medicine feeding unit 152 are respectively connected to the drug administration unit 120. Specifically, the gas outlet 1221 of the drug administration unit 120 is connected to the first medicine feeding unit 151 and the second medicine feeding unit 152. The anesthetic in the drug administration unit 120 is mixed with oxygen to obtain anesthetic gas, and the anesthetic gas flows out from the gas outlet 1221 of the drug administration unit 120 and enters the medicine feeding component 150. In some embodiments, when the target of the anesthesia device 100 is a small life form (such as a small animal, such as a small animal such as a mouse, rabbit, cat, etc.), the anesthetic gas flows out from the gas outlet 1221 of the drug administration unit 120, enters the first medicine feeding unit 151, and is fed to the small life form through the first medicine feeding unit 151. Optionally, the first medicine feeding unit 151 is connected to the lungs of the small life form through a coaxial tube. During the breathing process of the small life form, when the small life form inhales, the anesthetic gas enters the lungs of the small life form through the inner tube of the coaxial tube. When the small life form exhales, the inner tube is closed, and the exhaled gas passes through the gap between the inner tube and the outer tube of the coaxial tube, flows to the exhaust pipe of the coaxial tube, and is directly discharged into the atmosphere. The anesthesia operation process is simple. Since the demand for anesthetics for small life forms is extremely low. The proportion of anesthetics in the mixed gas introduced into the alveoli of the small life form is very low, and the content of unabsorbed anesthetics in the gas exhaled by the small life form is extremely small. Therefore, direct discharge into the atmosphere will not cause environmental pollution. Optionally, the first feeding unit 151 is a one-way conducting feeding unit, such as a one-way valve. The anesthetic gas can flow out from the gas outlet 1221 of the dosing unit 120, enter the first feeding unit 151, and flow out through the first feeding unit 151 to be fed to the living organism. The first feeding unit 151 can prevent the anesthetic gas from flowing back from the mouth and nose of the living organism into the first feeding unit 151, thereby avoiding the loss of anesthetic gas and causing inaccurate experimental dosage.

[0033] Optionally, the second medicine feeding unit 152 is a one-way valve, which is used to control the gas to only flow out of the anesthesia device 100 to prevent the gas from flowing back into the body of the living being.

[0034] In some embodiments, the anesthesia device 100 further includes a diverter 180, which is disposed between the drug feeding assembly 150 and the drug administration unit 120, and the diverter 180 is in communication with the drug feeding assembly 150 and the drug administration unit 120, respectively. In other words, the diverter 180 is in communication with the drug administration unit 120, the first drug feeding unit 151, and the second drug feeding unit 152, respectively. After the anesthetic gas supplied by the drug administration unit 120 enters the diverter 180, it is divided into two paths and flows out through the first drug feeding unit 151 and the second drug feeding unit 152, respectively. Specifically, after the gas flowing out of the drug administration unit 120 enters the diverter 180, it enters the drug feeding assembly 150 under the control of the diverter 180, and the diverter 180 controls the gas flowing out of the gas outlet 1221 of the drug administration unit 120 to enter the first drug feeding unit 151 or the second drug feeding unit 152. In some embodiments, the diverter 180 is a two-position three-way valve.

[0035] In some embodiments, the drug delivery unit 120 includes a flow meter 121 and a drug delivery device 122. The flow meter 121 is located between the oxygen supply unit 110 and the drug delivery device 122, and is connected to the oxygen supply unit 110 and the drug delivery device 122 respectively. The oxygen provided by the oxygen supply unit 110 enters the flow meter 121 through the first supply port 111, flows out and enters the drug delivery device 122, and the oxygen is mixed with the gaseous anesthetic in the drug delivery unit 120 to form anesthetic gas; the flow meter 121 is used to detect the flow rate of oxygen from the oxygen supply unit 110 into the drug delivery device 122, and the oxygen output of the oxygen supply unit 110 is controlled according to the value detected by the flow meter 121. Combined with the amount of gaseous anesthetic provided by the drug delivery device 122, the two cooperate with each other to control the concentration of the anesthetic gas provided by the drug delivery unit 120, so that the drug delivery unit 120 can provide anesthetic gas of a preset concentration and a preset dose, so as to obtain anesthetic gas of a suitable concentration to anesthetize the living body. The drug delivery device 122 is used to provide a preset dose of anesthetic to anesthetize the living body.

[0036] Optionally, the drug delivery device 122 is a vaporizer, and the anesthetic may be, but is not limited to, isoflurane and ether. The drug delivery device 122 processes the anesthetic into a gaseous state by controlling temperature and time, and cooperates with a flow meter. When oxygen passes through the flow meter and enters, it mixes with oxygen to form an anesthetic gas of a preset concentration.

[0037] Optionally, the oxygen supply unit 110 may be connected to and communicate with an external oxygen source, and the external oxygen source may be, but is not limited to, an oxygen cylinder or a wall gas source.

[0038] Optionally, the oxygen supply unit 110 further includes a second supply port 112, which is connected to the medicine feeding assembly 150 and is used to directly deliver oxygen to the living body to revive the living body. The second supply port 112 is also connected to a diverter, and the oxygen provided by the oxygen supply unit 110 flows out through the second supply port 112, is diverted by the diverter, and is respectively supplied to the first medicine feeding unit 151 and the second medicine feeding unit 152, and flows out from the first medicine feeding unit 151 and the second medicine feeding unit 152 to be delivered to the living body.

[0039] In some embodiments, the oxygen provided by the external oxygen source enters from the inlet of the oxygen supply unit 110 and flows out through the first supply port 111 or the second supply port 112. The oxygen flowing out of the first supply port 111 is used as a carrier of anesthetics in the process of anesthetizing a living organism, and the oxygen flowing out of the second supply port 112 directly enters the body of the living organism to revive the anesthetized living organism.

[0040] In some embodiments, the anesthesia device 100 further includes a switch 170, which is disposed between the second supply port 112 and the diverter 180, and is used to control the opening and closing of the oxygen supply of the second supply port 112 of the oxygen supply unit 110. When the anesthesia device 100 is in the process of anesthetizing a living being, the switch 170 is closed, and the oxygen flowing out of the second supply port 112 will not enter the body of the living being, thereby avoiding its influence on the anesthesia effect; when the living being that needs to be anesthetized wakes up, the switch 170 is turned on, the drug delivery device 122 is closed, and the oxygen flowing out of the second supply port 112 dilutes the anesthetic gas inside the anesthesia device 100 and enters the body of the living being to promote rapid awakening.

[0041] Specifically, the second supply port 112 is connected and communicated with the switch 170, the switch 170 is connected and communicated with the diverter 180, the diverter 180 is connected and communicated with the medicine feeding assembly 150, and the oxygen flowing out of the second supply port 112 passes through the switch 170, enters the diverter 180, and then flows out from the diverter 180, enters the medicine feeding assembly 150, and is respectively supplied to the first medicine feeding unit 151 and the second medicine feeding unit 152; the switch 170 is used to control the flow of oxygen in the gas path where it is located, and optionally, the switch 170 is a valve. When the life form needs to be awakened after the anesthesia is completed, the drug delivery device 122 is closed, and the switch 170 is turned on, so that the oxygen from the second supply port 112 passes through the switch 170 to the diverter 180, and according to whether the anesthetized object is a small life form or a non-small life form, the oxygen is controlled by the diverter 180 to enter the first medicine feeding unit 151 or the second medicine feeding unit 152, and then enters the life form. Oxygen can dilute the anesthetic in the gas circuit to prevent the living organism from continuing to inhale anesthetic gas of a preset concentration. After oxygen enters the body of the living organism, it can promote the living organism to wake up quickly and relieve the paralysis state.

[0042] Optionally, the anesthesia device 100 further includes a pressure gauge 130, which is respectively connected to the drug administration unit 120, the drug feeding component 150 and the oxygen supply unit 110, and is used to detect the pressure between the drug administration unit 120 and the drug feeding component 150, and the pressure between the oxygen supply unit and the drug feeding component. Furthermore, the pressure gauge 130 is respectively connected to the second supply port 112 and the drug feeding component 150, and is also used to detect the pressure between the second supply port 112 and the drug feeding component 150. In the process of the drug feeding component 150 delivering oxygen to the living body, the pressure gauge 130 monitors the air pressure of the gas circuit to prevent excessive air pressure from causing damage to the body of the living body.

[0043] In some embodiments, the pressure gauge 130 is connected to the dosing unit 120 and the medicine feeding component 150, and is used to detect the pressure between the dosing unit 120 and the medicine feeding component 150. In some embodiments, the pressure gauge 130 is arranged on the air path between the dosing unit 120 and the medicine feeding component 150. Specifically, the dosing unit 120 is connected and communicated with the pressure gauge 130, the pressure gauge 130 is connected and communicated with the diverter 180, the diverter 180 is connected and communicated with the medicine feeding component 150, and the gas flowing out of the dosing unit 120 enters the diverter 180 through the pressure gauge 130, and then enters through the air inlet of the medicine feeding component 150. The pressure gauge 130 can monitor the air path pressure during the process of the breathing assistance unit 140 adjusting the breathing of the living body to avoid excessive air pressure causing damage to the body of the living body.

[0044] Optionally, the anesthesia device 100 further includes a breathing assistance unit 140, which is connected to the medicine feeding assembly 150 and is used to assist the living body in breathing. In some embodiments, the breathing assistance unit 140 is connected to the gas path between the drug delivery unit 120 and the diverter 180, and the gas flowing out of the gas outlet 1221 of the drug delivery unit 120 passes through the breathing assistance unit 140 and enters the diverter 180; the breathing assistance unit 140 is used to assist the breathing of the living body, and the breathing assistance unit 140 can be, but is not limited to, a squeezable air bag or an air pump. In some embodiments, after being anesthetized, the living body cannot breathe autonomously, and the CO2 in the body cannot be discharged through breathing, which may cause CO2 poisoning. To avoid CO2 poisoning of the living body, after the living body is anesthetized, the air bag is squeezed to increase the air pressure, and the gas is pressed into the body of the living body, so that the living body continues to take in anesthetic gas containing oxygen to maintain the anesthetized state of the living body. The air bag is relaxed to reduce the air pressure and extract the CO2 gas in the body of the living body to avoid CO2 poisoning of the living body. The vital signs of the living body are kept stable by repeatedly squeezing and relaxing the air bag. The time and frequency of squeezing and relaxing the air bag can also be adjusted to control the time for the anesthetic gas to diffuse in the body of the living body, thereby controlling the anesthetic effect.

[0045] Optionally, the anesthesia device 100 further includes a recycling component 160, and the recycling component 160 is connected to the medicine feeding component 150, and the recycling component 160 is used to purify the gas exhaled by the living body and then feed it to the living body again through the medicine feeding component 150. Specifically, when the anesthesia device 100 acts on a non-small life form (for example, a large animal, such as a large animal such as a cow, sheep, horse, etc.), the anesthetic gas dosing unit 120 flows out, enters the second medicine feeding unit 152, and is fed to the non-small life form (i.e., a large life form) through the second medicine feeding unit 152. Non-small life forms require a large amount of anesthetic, but after inhaling the anesthetic gas, most of the anesthetic enters the alveoli, and a small part will be exhaled, resulting in a waste of resources. To this end, during the breathing process of the non-small life form, when the non-small life form inhales, the anesthetic gas enters the lungs of the non-small life form through the second feeding unit 152, and when the non-small life form exhales, the exhaled gas enters the recycling component 160. The recycling component 160 purifies the gas exhaled by the non-small life form, and the purified gas flows out of the recycling component 160 and enters the second feeding unit 152 again, and enters the body of the non-small life form as it breathes, thereby achieving a high utilization rate of the anesthetic.

[0046] Optionally, the recycling component 160 includes: a collection unit 161 for collecting the gas exhaled by the living body; and a purification unit 162, the purification unit 162 is connected to the collection unit 161, and is used to purify the gas; the purification unit 162 is also used to connect to the medicine feeding component 150, and is used to feed the purified gas to the living body again. Optionally, the second medicine feeding unit 152 is also connected to the purification unit 162. In some embodiments, when the object of the anesthesia device 100 is a non-small life form, when the non-small life form inhales, the anesthetic gas enters the lungs of the non-small life form through the second medicine feeding unit 152, and when the non-small life form exhales, its exhaled gas enters the collection unit 161. Specifically, the gas exhaled by the living body enters from the collection unit 161, flows out and enters the purification unit 162, and after the gas exhaled by the living body is processed by the purification unit 162, flows out from the purification unit 162, enters the medicine feeding component 150, and enters the living body after flowing out.

[0047] In some embodiments, the purification unit 162 is a CO2 absorption device, which contains a CO2 absorbent, which may be, but is not limited to, calcium hydroxide or soda lime. The CO2 absorbent is a porous loose structure with a large adsorption surface area, good air permeability, a fast CO2 absorption rate, and does not react with anesthetics to avoid consuming anesthetics. The CO2 absorption device absorbs and purifies the CO2 exhaled by the non-small life form, and the purified gas enters the second medicine feeding unit 152 again, and enters the body of the non-small life form again with its breathing, thereby achieving a high utilization rate of the anesthetic.

[0048] In some embodiments, the collection unit 161 is a one-way valve, which is used to control the gas to flow into the anesthesia device only, and prevent the gas exhaled by the living body from being sucked back into the body again.

[0049] Optionally, the recycling component 160 further includes a pressure limiting valve 163, which connects the collection unit 161 and the purification unit 162, and is used to control the air pressure of the collection unit 161 entering the purification unit 162. The pressure limiting valve 163 is arranged between the collection unit 161 and the purification unit 162, and the collection unit 161 is connected and communicated with the pressure limiting valve 163, and the pressure limiting valve 163 is connected and communicated with the purification unit 162. The gas exhaled by the living body enters from the collection unit 161, flows out, enters the pressure limiting valve 163, and then flows out into the purification unit 162. After being processed by the purification unit 162, the gas flows out from its outlet, enters the second medicine feeding unit 152, and is then inhaled by the non-small living body. The pressure limiting valve 163 can control the gas to flow out of the anesthesia device 100 only and not flow back. The pressure limiting valve 163 can also control the air pressure of the air circuit. As the living body breathes, the gas in the air circuit will gradually increase and the air pressure will gradually increase. When the air pressure increases to a set value, the pressure limiting valve 163 automatically deflates the air to maintain the air pressure of the air circuit below the set value. If the pressure limiting valve 163 is not provided and only a one-way pipeline for exhaust is provided, during the breathing process of the living body, although the living body can normally inhale the anesthetic gas when inhaling, when the living body exhales, most of the gas in the air circuit enters the CO2 Absorption device, a part of the remaining exhaled gas will be discharged from the anesthesia device 100 through the one-way pipeline. At this time, the exhalation of the living body is too sufficient, resulting in an increase in the exhaled anesthetic, and it will also cause the alveoli to close early, and the action time of the anesthetic and the alveoli will be shortened, so that the living body enters the anesthesia state slowly. After the pressure limiting valve 163 is set, the pressure limiting valve 163 can maintain a certain positive pressure in the respiratory tract at the end of the exhalation of the living body, so that the exhalation of the living body is insufficient, the early closure of the alveoli is avoided, and the alveoli expand more evenly, so as to achieve the purpose of increasing blood oxygen, thereby achieving a better anesthesia effect.

[0050] In some embodiments, the anesthesia device 100 further includes a filter device, which is connected to the air outlet of the coaxial tube and the air outlet of the pressure limiting valve 163, and is used to absorb anesthetics in the waste gas to prevent the anesthetics from leaking into the environment, thereby further protecting the environment. In some embodiments, the anesthesia device 100 further includes a housing 200 and a top cover 300.

[0051] Please refer to Figure 4, which is a gas flow diagram of the anesthesia device. In some embodiments, when the anesthesia device acts on a small life form, the switch is first turned off, and then oxygen is introduced. After the oxygen passes through the drug delivery unit, the anesthetic in the drug delivery unit is mixed with oxygen to obtain a mixed gas with a preset anesthetic gas concentration. The mixed gas is diverted by the diverter and flows to the first drug feeding unit. The small life form inhales the mixed gas and is anesthetized. The waste gas exhaled by the small life form can be directly discharged into the outside atmosphere because the amount of anesthetic contained in it is extremely small; when the small life form is to be awakened, the drug delivery unit is turned off to stop providing anesthetic gas, and the switch is turned on. The oxygen is diverted to the first drug feeding unit through the diverter and is inhaled by the small life form to awaken the small life form.

[0052] When the object of the anesthetic device is a non-small life form, the switch is first turned off, and then oxygen is introduced. After the oxygen passes through the dosing unit, the anesthetic in the dosing unit is mixed with oxygen to obtain a mixed gas with a preset anesthetic gas concentration. The mixed gas is diverted by the diverter and flows to the second feeding unit. The non-small life form inhales the mixed gas and is anesthetized. The gas exhaled by the non-small life form is collected by the collection unit and sent to the purification unit to remove CO2 therein and recover the unabsorbed anesthetic. The recovered anesthetic is sent to the second feeding unit and is absorbed by the non-small life form together with the new mixed gas, thereby improving the utilization rate of the anesthetic. When the non-small life form is to be awakened, the dosing unit is turned off to stop providing anesthetic gas, and the switch is turned on. The oxygen is diverted to the first feeding unit through the diverter and is inhaled by the non-small life form to awaken the non-small life form.

[0053] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present application, and these improvements and modifications are also regarded as the scope of protection of the present application.
