[0002] Gas anesthesia is widely used in various types of surgeries as an effective means of anesthesia. The issue of anesthetic waste gas treatment has received more and more attention. Generally, during the implementation of inhalation general anesthesia, open or semi-open anesthesia methods are used, and anesthetic gases are directly mixed with indoor air, causing air pollution in the operating room. Even if a semi-closed or closed anesthesia machine is used, anesthetic gases can still be discharged from the mask, exhaust piston, threaded pipe, etc., polluting the surgical environment.

[0003] For example, patent number CN202020266679.X discloses an anesthetic waste gas extraction device, which includes an extraction device body, a dust suction pipe and a dust suction pump.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] like Figures 1 to 6 As shown, the utility model provides an anesthetic waste gas extraction device for anesthesia, including a moving mechanism 2, the moving mechanism 2 includes a track 21 fixed on the top of the operating room, a "T"-shaped slide groove is arranged at the lower end of the track 21, a T-shaped slider 22 fixed to the upper end of the outer shell 1 is slidably arranged in the T-shaped slide groove, rectangular grooves are arranged on both sides of the T-shaped slider 22, and rollers 23 rolling in the "T"-shaped slide groove of the track 21 are arranged in the rectangular groove through a rotating shaft, thereby achieving a limiting effect and preventing the outer shell 1 from falling. At the same time, the rollers 23 are arranged to facilitate the movement of the outer shell 1 and can effectively reduce the friction between the T-shaped slider 22 and the track 21. The nurse can adjust the position of the device in real time, thereby facilitating the use of the device without interfering with the doctor.

[0033] Both sides of the inner cavity of the outer shell 1 are fixed to the fixed ends of the electric push rods 13 by screws, and the two electric push rods 13 are arranged diagonally to effectively improve the stability of the inner shell 4. It should be noted that the extension and retraction of the two electric push rods 13 need to be synchronized and controlled by the same controller. The extension ends of the two electric push rods 13 are fixed to the extension plates on both sides of the inner shell 4 by threads (such as Figure 4 As shown in the figure, a filter core 6 for filtering anesthetic waste gas is detachably inserted into one side of the inner cavity of the inner shell 4, and a plurality of symmetrical card slots 15 are provided on one side of the inner shell 4. A sealing strip 14 is glued and fixed around the filter core 6. The filter core 6 is clamped in the card slot 15 and the sealing strip 14 abuts against the card slot 15 to achieve sealing, thereby dividing the inner cavity of the inner shell 4 into a plurality of chambers (such as Figure 2 As shown), multiple filter elements 6 can be made of different materials, such as activated carbon, melt-blown cloth, etc., and need to be set according to the anesthetic gas, so that different anesthetic waste gases can be extracted and filtered. The lower end face of the sealing strip 14 protrudes from the open end face of the lower end of the inner shell 4. The protruding sealing strip 14 is squeezed by force to achieve better sealing. The inner cavity of the inner shell 4 is away from the filter element 6 and is fixed with an exhaust fan 5 for exhausting air. The driving motor of the exhaust fan 5 is preferably a silent motor to avoid generating excess noise in the operating room and affecting the doctor's operation. At the same time, the exhaust fan 5 draws air to achieve negative pressure inside the inner shell 4.

[0034] The outer shell 1 has two sides opposite to the front side of the filter element 6, through holes 8 and 9 are respectively provided. Figure 2As shown in the figure, a filter screen 17 for filtering is fixed on one side of the through hole 3 9, and through holes 1 7 are provided on both sides of the inner shell 4, which correspond to and communicate with through holes 2 8 and 3 9; sealing gaskets are glued and fixed around the outer periphery of the two through holes 1 7, and the sealing gaskets fill the gap between the inner shell 4 and the outer shell 1, and make through hole 1 7, through hole 2 8 and through hole 3 9 the same complete channel to avoid air leakage. It should be noted that in order to better move the inner shell 4 into the inner cavity of the outer shell 1, the upper ends of the two sealing gaskets are provided with inclined chamfers, and at the same time, the opening at the lower end of the outer shell 1 is provided with two bevels corresponding to the sealing gaskets and inclined outward.

[0035] A connection cover 16 connected to the second through hole 8 is fixedly disposed on one side of the outer shell 1, and a bellows 10 for collecting anesthetic waste gas is fixedly disposed on one side of the connection cover 16. The bellows 10 is made of medical sterile material.

[0036] The swing mechanism 3 includes a fixed round seat 31 fixed to the outer wall of the outer shell 1 and located below the connecting cover 16. The swing mechanism 3 also includes a damping shaft 38 embedded and fixed in the middle of the fixed round seat 31. The movable end of the damping shaft 38 is embedded and fixed in the middle of the rotating seat 32. The setting of the damping shaft 38 can make the slide bar 34 stay at any position to achieve the supporting effect. The lower end of the rotating seat 32 is fixed with a sleeve 33. The inner cavity of the sleeve 33 is longitudinally slidably provided with a slide bar 34. The lower end of the slide bar 34 is connected to the upper end of the fixed seat 35. It is fixed, and the steel ball 37 and the groove at the lower end of the fixed seat 35 are rotated. It should be noted that two-thirds of the steel ball 37 rotates in the groove at the lower end of the fixed seat 35 to achieve the limiting effect. A connecting rod 36 is fixed to the lower end of the steel ball 37, and a plurality of damping rings 39 are fixed on the surface of the slide bar 34 to increase the friction force. The plurality of damping rings 39 abut against the inner wall of the sleeve 33. This arrangement can make the slide bar 34 stay at any position of the sleeve 33. At the same time, a limiting device for the slide bar 34 is also provided at the lower end of the sleeve 33 (not shown in the figure).

[0037] A magnet (not shown in the figure) is embedded in the groove at the lower end of the fixing seat 35, and the magnet and the steel ball 37 can be fixed by magnetic attraction. The fixing seat 35 and the steel ball 37 can achieve a movement similar to a universal ball. The lower end of the connecting rod 36 is fixedly connected to the fixing plate 12. The fixing plate 12 can be set to a larger size to facilitate the nurse to adjust the position of the wind collecting hood 11. At the same time, the corners of the fixing plate 12 are set to be rounded. The lower end of the fixing plate 12 is fixed with the wind collecting hood 11, which is preferably made of medical sterile silicone material. The end of the bellows 10 away from the connecting hood 16 passes through the fixed wind collecting hood 11 and the fixing plate 12 and is connected to the inner cavity of the wind collecting hood 11, thereby realizing the transportation of anesthetic waste gas.

[0038] The lower opening of the outer shell 1 is clamped with a sealing cover, and the upper end of the sealing cover is provided with a sealing sheet to achieve a sealing effect with the inner shell 4 and the outer shell 1. The sealing cover is fixed to the lower opening of the inner shell 4, and the surrounding edge of the sealing cover abuts against the lower opening of the outer shell 1 to achieve sealing.

[0039] Principle and process of this utility model:

[0040] The installation construction personnel select a suitable position according to the layout of the operating room and install the track 21 on the top of the operating room by bolts, and then suspend the purification device of the device.

[0041] When in use, the nurse holds the fixing plate 12 by hand and pulls it, and drives the outer shell 1 and the T-shaped slider 22 to move on the track 21 through the swing mechanism 3, so that the wind hood 11 is roughly located on the patient's side, and will not interfere with the doctor. Then, the nurse first pulls the fixing plate 12 and then drives the slide bar 34 to move in the sleeve 33 through the connecting rod 36, the steel ball 37, and the fixing seat 35, thereby changing the height of the wind hood 11. After the height is determined, the nurse rotates the fixing plate 12 by hand and then drives the steel ball 37 to rotate in the fixing seat 35 through the connecting rod 36. After rotating to a suitable position, the steel ball 37 stops in the fixing seat 35. This fixation is achieved by the magnetic attraction effect of the magnet and the steel ball 37. The magnet is embedded in the fixing seat 35 and cannot wear the steel ball 37. The above setting can make the wind hood 11 suspended around the patient to collect and extract the anesthetic waste gas. It can also be adjusted in real time.

[0042] Then, the nurse turns on the switch of the device, which enables the circuit inside the device to be connected. The external power grid provides power to the device and transmits power through the wires. At this time, the exhaust fan 5 is powered on and the fan blades rotate to discharge the air inside the inner shell 4 to the outside through the through hole three 9. The filter 17 is set to prevent external dust from entering the inner shell 4. A pipe can also be set outside the through hole three 9 to discharge the purified gas to the outside of the operating room.

[0043] The anesthetic waste gas enters the wind collecting hood 11, the bellows 10, the connecting hood 16, the through hole 2 8 and the through hole 1 7 of the outer shell 1 located on the side of the connecting hood 16, and then enters the interior of the inner shell 4. The anesthetic waste gas moves toward the exhaust fan 5, and the filter elements 6 arranged in sequence can filter the anesthetic waste gas.

[0044] The above structural setting can effectively reduce the concentration of anesthetic waste gas around the patient. At the same time, the device is suspended on the top of the operating room, which has the advantages of not occupying ground space and not interfering with doctors while maintaining the most efficient anesthetic waste gas extraction.

[0045] When replacing the filter element 6, the electric push rod 13 is energized, and the telescopic end of the electric push rod 13 extends out through the sealing cover to drive the inner shell 4 to move out of the inner cavity of the outer shell 1. At this time, the sealing cover is separated from the outer shell 1. This arrangement avoids the danger of maintenance personnel climbing up and allows the inner shell 4 to be moved downward for easy maintenance. The user then removes the screws to separate the sealing cover from the inner shell 4 and then pulls the filter element 6 out of the slot 15 to complete the replacement.
