[0032] Example 1

[0033] like Figure 1-Figure 5 As shown, the utility model provides an anesthesia machine that is easy to disinfect, including: a liquid medicine tank 101, a water inlet is provided on the top of the liquid medicine tank 101, a drain is provided on the bottom, and a booster pump 201 is provided on the water inlet; a water inlet pipe 203 and a rotating pipe 207, the water inlet pipe 203 is provided in the liquid medicine tank 101 and is connected and communicated with the water inlet, and the rotating pipe 207 is provided in the liquid medicine tank 101 and is rotatably connected and communicated with the water inlet pipe 203; a rotating drive device, connected to the bottom of the liquid medicine tank 101 and connected to the bottom of the rotating pipe 207, driving the rotating pipe 207 to rotate; a plurality of water spray pipes 209, the plurality of water spray pipes 209 are connected at intervals and communicated with the rotating pipe 207, and rotate with the rotating pipe 207, and a plurality of water spray troughs 210 are provided at intervals on the water spray pipes 209.

[0034] Specifically, the anesthesia machine mainly consists of a drug liquid tank 101, an ether regulating switch, a foldable bellows, and an inhalation and exhalation one-way valve and a bellows. This embodiment mainly describes the disinfection mechanism inside the drug liquid tank 101. Other components not specifically described are all existing technologies in the field, and their structures and principles are not repeated here.

[0035] The water inlet pipe 203 and the rotating tube 207 are connected by a rotating connection structure of a first connecting ring 204 and a second connecting ring 206, specifically: the water inlet pipe 203 is bolted to the output end of the boost pump 201, the first connecting ring 204 is welded to the bottom end of the water inlet pipe 203, the raised ring 205 of a T-shaped structure is welded to the bottom of the first connecting ring 204, the top of the second connecting ring 206 is provided with a T-shaped groove, the T-shaped raised ring 205 at the bottom of the first connecting ring 204 is rotatably connected to the T-shaped groove at the top of the second connecting ring 206, so that the first connecting ring 204 and the second connecting ring 206 can rotate relative to each other; the rotating tube 207 is welded to the bottom of the second connecting ring 206, so that the rotating tube 207 and the water inlet pipe 203 can rotate relative to each other. As for how to install the raised ring 205 of the T-shaped structure in the groove of the T-shaped structure, in this embodiment, a square-section annular groove can be first opened on the top of the second connecting ring 206, and then the raised ring 205 of the T-shaped structure is placed therein, and then annular retaining strips are welded on both sides of the notch of the square-section annular groove to form a T-shaped structure groove.

[0036] The booster pump 201 is used to pressurize the disinfectant to improve its jetting ability, so that when the rotating tube 207 rotates, it can contact a farther position in the medicine tank 101, thereby increasing the contact area of ​​the disinfectant. The disinfectant sprayed onto the inner wall of the medicine tank 101 flows down along the inner wall of the medicine tank 101 and converges to the drain outlet at the bottom for discharge.

[0037] The rotation driving device can specifically be a motor 202. The bottom end of the rotating tube 207 is closed and extends through the bottom of the medicine tank 101 to be connected to the output shaft of the motor 202. A sealing structure is provided at the through connection between the rotating tube 207 and the medicine tank 101 to prevent leakage of the disinfectant.

[0038] Example 2

[0039] The rotating tube 207 is vertically arranged in the liquid medicine tank 101, and a plurality of water spray pipes 209 are horizontally connected to opposite sides of the rotating tube 207, and a plurality of water spray pipes 209 are vertically spaced and connected to the upper part of the rotating tube 207. A plurality of spraying slots 208 are vertically and circumferentially opened at the lower part of the rotating tube 207 to increase the spraying area of ​​the disinfectant.

[0040] Specifically, the rotating tube 207 is coaxially connected to the water inlet pipe 203 and vertically, and the water spraying pipe 209 is perpendicular to the rotating tube 207, that is, connected to the rotating tube 207 in a horizontal line. The disinfectant passes through the water inlet pipe 203, the rotating tube 207 and the water spraying pipe 209 in sequence, and then sprays out from the water spraying groove 210 of the water spraying pipe 209. Since the water spraying pipe 209 rotates in the liquid medicine tank 101 along with the rotating tube 207, only one or two water spraying pipes 209 are required to be connected to both sides of the rotating tube 207, so that the inner wall of the liquid medicine tank 101 can be sprayed more comprehensively during the rotation process, thereby increasing the contact area of ​​the disinfectant.

[0041] Furthermore, when the water spray pipe 209 rotates to spray water, the spraying slot 208 at the lower portion of the rotating pipe 207 also sprays disinfectant outward, increasing the jet distance of the disinfectant by means of the centrifugal force of rotation, thereby disinfecting and cleaning the lower inner wall of the medicine tank 101.

[0042] Example 3

[0043] A plurality of ultraviolet lamps 401 for sterilizing the interior of the liquid medicine tank 101 are connected to the inner top wall of the liquid medicine tank 101. A plurality of lampshades 402 are connected to the inner top wall of the liquid medicine tank 101, and the plurality of ultraviolet lamps 401 are installed in the lampshades 402 respectively.

[0044] Specifically, the interior of the drug liquid tank 101 is sterilized by the ultraviolet lamp 401 , and the ultraviolet lamp 401 is protected by the lamp cover 402 .

[0045] Example 4

[0046] The drain outlet is connected to a drain pipe 211, and a valve 212 is provided on the drain pipe 211. A guide plate 102 is provided on the inner bottom wall of the liquid medicine tank 101, and the guide plate 102 guides the disinfectant to the drain outlet.

[0047] Specifically, the drain pipe 211 is connected to the outer wall of the bottom end of the liquid medicine tank 101 and communicates with the drain port, and the valve 212 is arranged on the outer wall of the drain pipe 211. The cross-sectional shape of the guide plate 102 is a right triangle, which is inclined toward one side of the drain port, guides the disinfectant to the drain port, and controls the discharge of the disinfectant through the valve 212.

[0048] Example 5

[0049] A support plate 302 is provided below the liquid medicine tank 101, and a damping spring shock absorber 301 is provided between the liquid medicine tank 101 and the support plate 302. A universal wheel 303 is provided at the bottom of the support plate 302, and a handle 304 is provided on the support plate 302. An anti-slip cover 305 is provided on the handle 304.

[0050] Specifically, the damping spring shock absorber 301 is bolted to the bottom of the liquid medicine tank 101, and the support plate 302 is bolted to the bottom of the damping spring shock absorber 301. There are four damping spring shock absorbers 301 and they are evenly distributed at the bottom of the liquid medicine tank 101. Four universal wheels 303 are bolted to the bottom of the support plate 302 to facilitate the movement of the liquid medicine tank 101, and a handle 304 is bolted to the side wall of the support plate 302 to facilitate pushing the liquid medicine tank 101. An anti-skid cover 305 is sleeved on the outer wall of the support plate 302 to improve the anti-skid performance of the handle 304, and a plurality of anti-skid grooves 306 are provided on the outer wall of the anti-skid cover 305.

[0051] When the medicine liquid tank 101 needs to be moved, the medicine liquid tank 101 can be moved by using the handle 304 and the universal wheel 303. When the medicine liquid tank 101 is in use, the damping spring shock absorber 301 can reduce the shock of the medicine liquid tank 101 to prevent the medicine liquid tank 101 from shaking and affecting the operation on the patient, thereby improving the stability of the device.

[0052] How this device works:

[0053] When it is necessary to disinfect the inside of the liquid medicine tank 101, the booster pump 201, the motor 202 and the ultraviolet lamp 401 can be connected to an external power source, and then the external pipeline can be connected to the disinfectant pool, and then one end of the external pipeline can be connected to the booster pump 201, and then the booster pump 201 is started, and the booster pump 201 pumps the disinfectant into the water inlet pipe 203, the rotating pipe 207 and the water spray pipe 209 in sequence; at this time, the motor 202 is started again, and the motor 202 drives the rotating pipe 207 and the water spray pipe 209 rotates, so that the disinfectant can be rotated to contact the inner wall of the medicine tank 101, thereby increasing the contact area between the inner wall of the medicine tank 101 and the disinfectant; after the disinfection of the medicine tank 101 is completed, the valve 212 can be opened to allow the disinfectant to be guided by the guide plate 102 to the drain pipe 211, and then discharged to the outside of the medicine tank 101; then the ultraviolet lamp 401 is turned on, and the ultraviolet lamp 401 can disinfect the inside of the medicine tank 101 again to improve the cleanliness of the inside of the medicine tank 101.
