Description

Technical Field

[0001] The utility model relates to the technical field of medical waste gas treatment, in particular to an anesthesia waste gas treatment device for an anesthesia operating room. Background Art

[0002] With the increasing use of inhaled anesthetics in operating rooms, the anesthetic gas or steam diffused in the operating room during surgery will inevitably cause pollution to the operating room environment. Long-term exposure to this polluted environment of trace anesthetic waste gas may have an adverse effect on the physical and mental health of operating room staff, and waste gas treatment equipment is needed to treat the anesthetic waste gas.

[0003] Existing waste gas treatment devices have few means of treating anesthetic waste gas, and in actual use, the effect is not very ideal, and it is difficult to effectively remove harmful substances in anesthetic waste gas; at the same time, inhaled anesthetics are a type of volatile liquid or gas, which is extremely easy to evaporate, and the problem of volatility is not considered during the treatment process of existing devices.

[0004] For example, a new patent with the announcement number CN218687764U discloses an anesthetic waste gas treatment device for an anesthesia operating room, which belongs to the field of medical device technology. By providing an inhalation mechanism, the first fan is started, and the exhaust gas is inhaled by the suction nozzle. Through the inhalation pipe and the inhalation part, at the rotary separator assembly, the inhaled solid particles are removed after centrifugation through the high-speed rotation of the rotary separator assembly, and the anesthetic waste gas is preliminarily treated by purification through the first filter plate and the second filter plate at one time; and by providing a refrigeration mechanism, the temperature of the outside air is reduced after being treated by the condenser, and the temperature is reduced in the condensation chamber and the disinfection mechanism through the main air duct and the branch air duct, so as to prevent a large amount of volatilization during the treatment of the anesthetic waste gas and reduce the treatment effect; by providing a disinfection mechanism, the anesthetic waste gas after the condensation treatment is transported to below the liquid level of the absorption treatment agent in the disinfection mechanism, and through stirring, the anesthetic waste gas and the agent are fully mixed and contacted, so that the treatment effect of the anesthetic waste gas is better.

[0005] In response to the above problems, the above patent provides a solution. Although the processing device can prevent the anesthetic gas from volatilizing again, it only mixes the medicine and the anesthetic gas and then discharges them into the atmosphere. The medicine alone cannot filter the anesthetic gas, so the anesthetic gas discharged from the processing device still has a health impact on the human body.

[0006] In view of the above reasons, the utility model proposes an anesthetic waste gas treatment device for an anesthesia operating room to solve the above technical problems. Utility Model Content

[0033] like Figure 1-5As shown, the utility model provides an anesthetic waste gas treatment device for an anesthesia operating room, comprising: a box body 1, an absorption treatment component 2 is arranged on the box body 1, the absorption treatment component 2 comprises an air pump 201, an absorption pipe 202, a purification chamber 204, an exhaust pipe 205 and a water inlet 206, wherein the air pump 201 is installed on the top surface of the box body 1, the input end of the air pump 201 is located outside the box body 1, the absorption pipe 202 is connected to the input end of the air pump 201, a filter screen can be installed at the free end of the absorption pipe 202 to prevent the inhalation of debris, the purification chamber 204 is arranged inside the box body 1, the purification chamber 204 is filled with an alkaline medium, and ... The output end of 201 is connected to the interior of the purification chamber 204, one end of the exhaust pipe 205 is connected to the output end of the vacuum pump 201, and the other end extends to the interior of the purification chamber 204 and extends downward below the liquid surface of the alkaline medium. The water inlet 206 is opened at the top of the box body 1 and is connected to the purification chamber 204 through the water inlet pipe 207. The alkaline medium can be introduced into the purification chamber 204 through the water inlet 206 and the water inlet pipe 207. The alkaline medium can absorb and react carbon dioxide and acidic gases in the anesthetic waste gas. A filter component 3 is provided on one side of the purification chamber 204, and particulate matter can be filtered through the filter component 3.

[0034] In this embodiment, the alkaline medium is sodium lime water, which has strong alkalinity and can remove CO 2 、SO 2 , HCl, H 2 S and other acidic gases. Therefore, the acidic gas in the anesthetic waste gas can be removed through sufficient reaction after passing through sodium lime water, which solves the problem that the existing technology only mixes the agent and the anesthetic gas and then discharges it into the atmosphere, and the anesthetic gas cannot be filtered, and still causes health effects on the human body after discharge.

[0035] In this embodiment, the purification chamber 204 is separated from the filter component 3 by a baffle plate 203, the water inlet pipe 207 can pass through the baffle plate 203 to communicate with the purification chamber 204, and the purification chamber 204 and the space where the filter component 3 is located are connected through the top of the baffle plate 203, and the anesthetic waste gas after reacting with sodium lime water enters the filter component 3 through it for secondary filtration.

[0036] In this embodiment, if Figure 1 , 5 As shown, the water inlet 206 is installed with a sealing cover 6, and the sealing cover 6 is connected to the outer periphery of the water inlet 206 through threads. A sealing gasket 7 is installed in the sealing cover 6, and the bottom end of the sealing gasket 7 extends into the water inlet 206, which can ensure that the water inlet 206 is relatively sealed when in use to prevent the anesthetic waste gas from volatilizing before being filtered.

[0037] like Figure 3As shown, the filter assembly 3 includes a limiting plate 301, a HEPA filter layer 302, a silica gel layer 303 and an activated carbon layer 304. The limiting plate 301 is located on one side of the barrier plate 203 and is fixedly connected to the inner top wall of the box body 1. The HEPA filter layer 302, the silica gel layer 303 and the activated carbon layer 304 are sequentially arranged from bottom to top between the limiting plate 301 and the inner wall of the box body 1. After being absorbed by the alkaline medium, the anesthetic waste gas is filtered and discharged from the bottom of the limiting plate 301 through the HEPA filter layer 302, the silica gel layer 303 and the activated carbon layer 304 in turn. Among them, the HEPA filter layer 302 can effectively remove tiny particles in the gas, such as dust, dandruff, hair, etc., and the silica gel layer 303 subsequently absorbs part of the water vapor and carbon dioxide, which can further remove harmful components such as certain organic matter. The activated carbon layer 304 can adsorb acidic objects such as various anesthetic drug residues due to its strong adsorption capacity.

[0038] like Figure 2 As shown, an air outlet pipe 10 is provided on the surface of the box body 1 just above the activated carbon layer 304 , and both ends of the air outlet pipe 10 are respectively connected with the inside and outside of the box body 1 , and the anesthetic waste gas filtered by the filter component 3 is discharged through the air outlet pipe 10 .

[0039] like Figure 2 As shown, an inclined portion 8 is provided at the bottom of the purification chamber 204, the inner side of the inclined portion 8 is higher than the outer side, and the inclined portion 8 is located on one side of the baffle plate 203, and the inclined portion 8 is located below the exhaust pipe 205. A drain plug 9 is provided at one side of the bottom of the box body 1, one end of the drain plug 9 extends to the inside of the purification chamber 204, and the drain plug 9 is located at the lower side of the inclined portion 8. When the absorption is completed, the drain plug 9 is opened, and the alkaline medium in the purification chamber 204 can be discharged from the hole of the drain plug 9.

[0040] like Figure 1 , 4 As shown, at least one lower clamping jaw 4 is disposed on the outer side of the box body 1, and an upper clamping jaw 5 is disposed above the lower clamping jaw 4 to cooperate with it. The lower clamping jaw 4 and the upper clamping jaw 5 are both made of plastic material, and the two are bent in opposite directions and cooperate to form a circular clamping ring structure. When not in use, the absorption tube 202 can be clamped between the lower clamping jaw 4 and the upper and lower clamping jaws 5. Universal wheels 11 are disposed at the bottom of the box body 1 to facilitate the movement of the box body 1.

[0041] The working principle of the utility model device is as follows:

[0042] First, when the anesthetic waste gas is recovered, soda lime water is transported to the interior of the purification chamber 204 through the water inlet 206 and the water inlet pipe 207, and the vacuum pump 201 absorbs the anesthetic waste gas through the absorption pipe 202. The sealing cover 6 and the sealing gasket 7 make the water inlet 206 on the top of the box body 1 relatively sealed when in use to prevent the anesthetic gas from volatilizing before filtering. At this time, the anesthetic waste gas can be absorbed into the interior of the purification chamber 204 through the exhaust pipe 205. At this time, the anesthetic waste gas directly enters the soda lime water in the purification chamber 204, and the soda lime water absorbs carbon dioxide and other acidic gas components in the anesthetic waste gas. Then the carbon dioxide and other acidic gases are discharged around After passing through the baffle plate 203 and the limit plate 301, the remaining waste gas contacts the HEPA filter layer 302, which can effectively remove tiny particles in the gas, such as dust, dandruff, etc. The silica gel layer 303 then adsorbs part of the water vapor and carbon dioxide, which can further remove harmful components such as certain organic compounds. The activated carbon layer 304 can adsorb acidic substances remaining in various anesthetic drugs due to its strong adsorption capacity. At this time, the adsorbed and filtered gas is discharged to the outside of the box 1 through the outlet pipe 10. When cleaning is needed, the drain plug 9 can be unscrewed to allow the soda lime water and part of the residue of the anesthetic waste gas to be discharged from the box 1 along the inclined portion 8.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
