Description

Technical Field

[0001] The invention relates to the technical field of anesthetic waste gas treatment, in particular to a device for monitoring trace concentration of anesthetic waste gas and for modifying waste gas. Background Art

[0002] Anesthetic gases are a type of volatile drugs used for medical anesthesia. Their main function is to suppress the central nervous system during surgery or other medical procedures, making the patient painless or unconscious. They are used by inhalation and their concentration can be quickly adjusted to control the depth of anesthesia.

[0003] Anesthetic gas waste, also known as anesthetic gas waste (AGW), mainly refers to the excess or unabsorbed gas produced by the use of volatile anesthetics during medical procedures. It is mainly released from the anesthetic exhaled by the patient, equipment leakage, or escape from the connection.

[0004] If anesthetic waste gas is not properly treated, it may pose a health risk to staff and other patients in the medical environment. Long-term exposure to low-dose anesthetics can cause headaches, eye and throat irritation, nausea and vomiting, fatigue, memory and concentration loss, and potential effects on reproductive health. Therefore, it is necessary to use a waste gas modification device to detect and treat anesthetic waste gas.

[0005] However, during use, the existing waste gas modification device uses a catalyst to react with the anesthetic waste gas, rendering it harmless by reacting with the anesthetic components. The anesthetic waste gas is first introduced into the device, and then the catalyst is transported out to spray the anesthetic waste gas. However, since the anesthetic waste gas is in a gaseous state and the catalyst is in a droplet state when spraying it, the contact time between the two is limited, and the catalyst cannot be used to completely react the anesthetic components in the anesthetic gas, which will cause some of the anesthetic waste gas to dissipate. Summary of the invention

[0006] In view of the shortcomings of the prior art, the present invention provides a device for monitoring the trace concentration of anesthetic waste gas and for modifying the waste gas, which solves the problem in the prior art that the anesthetic waste gas is in a droplet state during spraying, while the anesthetic waste gas is in a gaseous state, so the contact time between the two is limited, and the anesthetic components in the anesthetic gas cannot be completely reacted, resulting in the dissipation of some anesthetic waste gas.

[0021] Working principle: first add the catalyst into the liquid storage tank along the water injection pipe, and then connect the exhaust gas to the tank body. At this time, drive the motor and use the motor to drive the transmission shaft to rotate. At this time, the transmission shaft will drive gear 2 and the driving wheel to rotate at the same time. Gear 2 will drive gear 1 and the rotating shaft to rotate. The rotating shaft can drive the stirring rod and the paddle to rotate. At this time, the paddle can draw out the air inside the tank body, and then draw the exhaust gas into the tank body, and the driving wheel can drive the belt to rotate the driven wheel. The driven wheel can drive the support rod, the connecting rod, the delivery pipe and the nozzle to rotate. At this time, drive the delivery pump to draw out the catalyst inside the liquid storage tank and make it enter the liquid storage cavity, and then pass through the support rod and the delivery pipe into the delivery pipe, and finally spray out from the nozzle. After the exhaust gas enters the tank body, it will enter cavity 1 along the air intake channel. At this time, the exhaust gas will contact and react with the catalyst, and then the exhaust gas and the catalyst will enter cavity 2 along the connecting channel. At this time, the stirring rod can break up the exhaust gas and the catalyst, so that the two are evenly mixed and fully integrated, and then enter the separation box through the exhaust channel and the connecting pipe. After entering the separation box, the exhaust gas and the catalyst will impact the paddle on one side of the inside. At this time, the paddle will rotate and drive the airflow to rotate, and the spiral strips set inside the separation box can also guide the airflow to perform spiral motion. At this time, the water mist will adhere to the inner wall of the separation box due to centrifugal force, and the airflow will enter the purification box along the guide pipe. After the airflow enters the purification box, open valve two at this time to allow the air to be discharged along the outlet pipe. When too much water droplets accumulate inside the separation box, open valve one to discharge the collected water. After the gas is discharged along the outlet pipe, the gas can be detected by the detector. When it is detected that the gas still contains anesthetic components, close valve two and open valve three at this time. At this time, the gas can be guided to cavity one to contact the catalyst again.

[0022] The present invention provides a device for monitoring the trace concentration of anesthetic waste gas and for modifying waste gas. It has the following beneficial effects:

[0023] 1. The present invention utilizes a power component to drive the rotating shaft and the conveying pipe to rotate, and then drives the blades to rotate to draw the exhaust gas into the box, and the nozzle can spray the catalyst in atomization, so that the exhaust gas and the catalyst can be evenly mixed, and the two can be broken up and further mixed after passing through the stirring rod, so the emission of exhaust gas can be avoided.

[0024] 2. The present invention provides paddles and spiral strips inside the separation box. Therefore, after the airflow and the catalyst enter the separation box, they will first impact the paddles and rotate them. The paddles and the spiral strips can drive the airflow to rotate, so that the moisture brought by the airflow can be thrown out to the inner wall of the separation box. Therefore, part of the anesthetic waste gas can be prevented from being discharged along the water droplets and finally volatilized into the room, thereby ensuring the treatment effect of the anesthetic waste gas.

[0025] 3. The present invention connects the air outlet pipe with cavity one by using a reflux pipe. Therefore, when the monitor detects that the gas containing anesthetic components is discharged, valve two is closed and valve three is opened, so that the air flow can enter cavity one and contact with the catalyst for another induction, thereby preventing the generation of anesthetic waste gas and ensuring the air safety in the space.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Please see attached Figure 1-Figure 3 The embodiment of the present invention provides a device for monitoring the trace concentration of anesthetic waste gas and modifying waste gas, including: a box body 1, in which a delivery pipe 2 is installed, and a plurality of nozzles 3 are installed on the outer wall of the delivery pipe 2, and the delivery pipe 2 is connected to the liquid storage tank 1202, and is used to spray out the catalyst in an atomized form; a rotating shaft 4, which is located at the top of the box body 1, and a stirring rod 5 and a paddle 6 are respectively arranged on both sides of the outer wall of the rotating shaft 4, and the paddle 6 is used to generate negative pressure when rotating to suck the gas into the box body 1 and mix it with the catalyst; a separation box 7, which is connected to the top of the box body 1, and is used to receive and separate the gas and the catalyst; a purification box 8, which is located at the bottom of the separation box 7, and the two are connected to each other, and the purification box 8 is used to receive and purify the gas discharged from the separation box 7.

[0037] During use, the catalyst can be sprayed out from the nozzle 3 through the delivery pipe 2, and it can be made into mist and dispersed in the box 1, and the stirring rod 5 and the paddle 6 are installed on the rotating shaft 4, because after the rotating shaft 4 rotates, the paddle 6 and the stirring rod 5 will be synchronously driven to rotate. The rotation of the paddle 6 can generate negative pressure to extract the air inside the box 1. At this time, the anesthetic waste gas is connected to the box 1, so that the anesthetic waste gas can enter the box 1. After the anesthetic waste gas enters the box 1, it will contact and react with the catalyst, thereby losing the anesthetic effect. Then the two will pass through the stirring rod 5. At this time, the stirring rod 5 can break up the two, so that the two are evenly mixed and fully reacted, thereby improving the quality of the anesthetic waste gas treatment and preventing it from diffusing into the air. The treated anesthetic waste gas will enter the separation box 7, and the separation box 7 can separate the water vapor from the waste gas. The separated gas can enter the purification box 8 for purification, thereby effectively avoiding the discharge of anesthetic waste gas.

[0038] Please see attached Figure 1 , Figure 2 and Figure 8A cavity 102 is provided in the middle of the box body 1, and a cavity 2 104 and an air inlet channel 101 are respectively provided at the inner top and the inner bottom of the box body 1, the air inlet channel 101 is communicated with the cavity 1 102, the cavity 1 102 and the cavity 2 104 are communicated with each other through a connecting channel 103, the delivery pipe 2 is located in the cavity 102, the rotating shaft 4 is located in the cavity 2 104, an exhaust channel 105 is provided on one side of the top of the box body 1, the exhaust channel 105 is communicated with the cavity 2 104, an installation cavity 106 is provided in the middle and upper part of one side of the outer wall of the box body 1, and a power component 9 is installed in the installation cavity 106, and the power component 9 is used to drive the delivery pipe 2 and the rotating shaft 4 to rotate.

[0039] The external anesthetic waste gas can be introduced into the cavity 102 through the air inlet channel 101, and the exhaust channel 105 is located on one side of the top of the box body 1 and is connected to the cavity 2 104 for discharging the treated gas. The cavity 102 serves as a mixing area for the catalyst and the anesthetic waste gas. Therefore, the delivery pipe 2 is installed in the cavity 102, and the catalyst is atomized by the nozzle 3, which can directly contact with the incoming anesthetic waste gas to produce a chemical reaction; the cavity 2 104 serves as an additional mixing and reaction space, and the rotating shaft 4 and the stirring rod 5 are located in the cavity 2 104, so the mixing of the waste gas and the catalyst can be further promoted, and the uniformity and efficiency of the reaction can be improved. The diameter of the connecting channel 103 is smaller than that of the cavity 102 and the cavity 2 104. Therefore, when the anesthetic waste gas and the catalyst pass through the connecting channel 103, the two can fully contact each other due to the smaller space; and the installation cavity 106 is the storage space of the power component 9, and the power component 9 can drive the delivery pipe 2 and the rotating shaft 4 to rotate.

[0040] Please see attached Figure 1 , Figure 2 and Figure 6 A liquid storage cavity 107 is provided in the middle of one side of the box body 1, a support rod 201 is provided on one side of the delivery pipe 2, a connecting rod 202 is provided on the adjacent sides of the support rod 201 and the delivery pipe 2, and a positioning ring 203 is fixedly connected to the outer wall of the adjacent sides of the support rod 201 and the delivery pipe 2, the connecting rod 202 is located in the liquid storage cavity 107, the positioning ring 203 on one side is located in the cavity 102, and the positioning ring 203 on the other side is located on the outer wall of the box body 1.

[0041] The connecting rod 202 can create an opening between the support rod 201 and the delivery pipe 2, so after the catalyst enters the liquid storage chamber 107, it can enter the delivery pipe 2 from the opening, which will not affect the rotation of the delivery pipe 2. The positioning ring 203 can be used to stably position the connecting rod 202 in the liquid storage chamber 107, thereby avoiding its position deviation.

[0042] Please see attached Figure 1-Figure 3The power assembly 9 includes a motor 901, which is fixedly connected in the installation cavity 106. The output end of the motor 901 is fixedly connected to a transmission shaft 902, and the middle part of the transmission shaft 902 is fixedly connected to a gear 2 904. One end of the rotating shaft 4 is equipped with a gear 1 903, and the gear 1 903 and the gear 2 904 are meshed and connected. One end of the transmission shaft 902 is fixedly connected to a driving wheel 905, and one end of the support rod 201 is fixedly connected to a driven wheel 906, and the driven wheel 906 and the driving wheel 905 are connected by a belt 907.

[0043] The driving motor 901 can drive the transmission shaft 902 to rotate, and the transmission shaft 902 can drive the gear 2 904 and the driving wheel 905 to rotate. The gear 2 904 can drive the gear 1 903 to rotate the rotating shaft 4, and then the stirring rod 5 and the paddle 6 can rotate. The driving wheel 905 can drive the driven wheel 906 to rotate through the belt 907. At this time, the driven wheel 906 can drive the support rod 201, the connecting rod 202 and the conveying pipe 2 to rotate.

[0044] Please see attached Figure 1 , Figure 2 , Figure 4 and Figure 6 The cavity 104 is fixedly connected with a bracket inside, the rotating shaft 4 is rotatably connected in the bracket, the bottom of the box 1 is fixedly connected with a base 10, the top surface of the base 10 is installed with a handle, and the bottom surface thereof is installed with a roller. A liquid storage tank 1202 is installed on one side of the top surface of the base 10, a delivery pump 12 is fixedly connected to the bottom of one side of the outer wall of the box 1, the delivery pump 12 is connected to the liquid storage tank 1202 through a connecting pipe 1203, a delivery pipe 1201 is installed at the output end of the delivery pump 12, the delivery pipe 1201 is connected to the liquid storage cavity 107, and a water injection pipe 1204 is arranged on the top surface of the liquid storage tank 1202, a drainage pipe 1205 is fixedly connected to the bottom of one side of the outer wall of the liquid storage tank 1202, and a valve 1206 is installed in the drainage pipe 1205.

[0045] The base 10 can provide stable support for the entire device, and is equipped with movable rollers, so that the device can be easily moved between different treatment areas, and the handle can be used for easy pushing and operation, and the bracket is fixed inside the cavity 104, so it can provide a stable installation platform for the rotating shaft 4 to ensure its stability during rotation; at the same time, the liquid storage tank 1202 and the delivery pump 12 are connected through the connecting pipe 1203, so the catalyst can be added to the liquid storage tank 1202 through the water injection pipe 1204, and the delivery pipe 2 and the liquid storage chamber 107 are connected through the feed pipe 1201, so after driving the delivery pump 12, the catalyst inside the liquid storage tank 1202 can be drawn out, so that it enters the liquid storage chamber 107 along the connecting pipe 1203, the delivery pump 12 and the feed pipe 1201, thereby realizing the delivery of the catalyst, and at the same time, when the use is over, the remaining catalyst can be discharged from the drain pipe 1205 by opening the valve four 1206.

[0046] Please see attached Figure 1 , Figure 4 and Figure 5 A connecting pipe 701 is fixedly connected to the bottom of one side of the separation box 7, and the connecting pipe 701 is communicated with the exhaust channel 105. A guide pipe 705 is fixedly connected to the bottom of the separation box 7, and the guide pipe 705 is communicated with the purification box 8. A support shaft 702 is rotatably connected to the top of the separation box 7, and a plurality of paddles 703 are installed on the outer wall of the support shaft 702. A spiral strip 704 is arranged at the bottom of the inner side wall of the separation box 7, and the height of the bottom of the guide pipe 705 is higher than the height of the bottom surface of the inner wall of the separation box 7. A sewage pipe 706 is fixedly connected to the bottom of the outer wall of the separation box 7, and a valve 707 is installed in the sewage pipe 706.

[0047] When the waste gas and the catalyst enter the separation box 7 along the cavity 2 104, the exhaust channel 105 and the connecting pipe 701 in sequence, they will hit the paddle 703, and the paddle 703 is fixed on the support shaft 702, so that the support shaft 702 and the paddle 703 can rotate, and the rotation of the paddle 703 can drive the catalyst and the anesthetic waste gas to rotate, thereby generating centrifugal force, which can throw the droplets to the inner wall of the separation box 7, thereby separating the liquid in the air flow. In addition, a spiral strip 704 is installed at the bottom of the inner wall of the separation box 7, and the spiral strip 704 can help guide the gas to spiral down, further increase the contact time between the gas and the box wall, and promote separation. Subsequently, the gas required for further purification is transported to the purification box 8 by using the guide pipe 705. And the sewage pipe 706 is installed at the bottom of the outer wall of the separation box 7, which is used to discharge the waste liquid collected during the separation process.

[0048] Please see attached Figure 1 , Figure 4 and Figure 7, a filter frame 801 is movably connected inside the purification box 8, a filter plate 802 is installed inside the filter frame 801, a handle 803 is installed on the top of the filter frame 801, a rubber sealing plate 804 is fixedly connected to the top of the outer wall of the filter frame 801, an air outlet pipe 805 is installed on the front side of the purification box 8, and a valve 2 806 and a monitor 807 are installed on one side of the air outlet pipe 805.

[0049] The filter frame 801 can be used to fix the filter plate 802, and the filter plate 802 can capture and absorb the anesthetic waste gas that remains in the gas after treatment. The rubber sealing plate 804 can provide a sealed environment between the filter frame 801 and the purification box 8 to prevent leakage of unpurified gas. When cleaning or replacing the filter plate 802, pull the handle 803 to pull out the filter frame 801, and insert it into the purification box 8 during installation. When the installation is completed, the filter frame 801 and the purification box 8 will squeeze the sealing plate 804 to form a seal, thereby facilitating the loading and unloading of the green plate. After the air is purified, valve two 806 is opened to discharge the treated gas, and the gas can be detected by using monitor 807. When the gas contains anesthetic components, at this time, valve two 806 is closed and valve three 1101 is opened, so that the airflow can enter cavity one 102 along the return pipe 11, so that the gas can contact and react with the catalyst again, thereby avoiding the release of anesthetic components until the ideal treatment effect is achieved.
