DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1 , Figure 2 As shown, an anesthetic drug spray device includes a volumetric flask 1, a transparent glass 11 is fixedly connected to the front of the volumetric flask 1, a scale 12 is opened on the outer wall of the transparent glass 11, a liquid inlet 13 is fixedly connected to the right part of the top of the volumetric flask 1, a liquid outlet 14 is fixedly connected to the bottom of the right end of the volumetric flask 1, a spray mechanism 2 is fixedly connected to the top of the volumetric flask 1, and an auxiliary mechanism 3 is fixedly connected to the outer wall of the spray mechanism 2.

[0025] The spray mechanism 2 and the auxiliary mechanism 3 cooperate with each other to spray anesthetic drugs on the throat of the patient.

[0026] like Figure 2 , Figure 4 As shown, the spray mechanism 2 includes a pump body 21, the bottom end of the pump body 21 is fixedly connected to the top end of the volumetric flask 1, the output end and the input end of the pump body 21 are fixedly connected to a hose 22, the left part of the hose 22 at the output end is fixedly connected to a connecting pipe 23, and the left end of the connecting pipe 23 is fixedly connected to a nozzle 29.

[0027] By opening the pump body 21, the anesthetic drug in the inner cavity of the volumetric flask 1 is extracted by the hose 22, the drug is transported to the connecting tube 23 by the hose 22, the drug is transported to the nozzle 29 by the connecting tube 23, and the drug is sprayed by the nozzle 29 to anesthetize the patient's throat.

[0028] like Figure 2 , Figure 3 As shown, the left part of the connecting tube 23 is slidably connected to the mask 24, the front and rear parts of the mask 24 are fixedly connected to the elastic band 25, the right part of the mask 24 is fixedly connected to the guide block 26, the outer wall of the guide block 26 is slidably connected to the inner wall of the connecting tube 23, and the outer shape of the connecting tube 23 is rectangular.

[0029] The elastic band 25 is hung behind the patient's ear to fix the mask 24. When worn, the mask 24 is close to the patient's face, and the mask 24 drives the guide block 26 to slide synchronously on the inner wall of the connecting tube 23. The guide block 26 limits the mask 24 so that the mask 24 will not rotate on the outer wall of the connecting tube 23, thereby achieving a limiting effect.

[0030] like Figure 2 , Figure 4 As shown, the left part of the connecting tube 23 is slidably connected with an arc plate 27, the inner wall of the arc plate 27 is fixedly connected with a positioning block 28, the outer wall of the positioning block 28 is plugged into the inner wall of the connecting tube 23, and the positioning block 28 is made of rubber.

[0031] By pulling the arc plate 27, the arc plate 27 slides on the outer wall of the connecting tube 23, and at the same time, the arc plate 27 drives the positioning block 28 to move synchronously, so that the positioning block 28 moves on the inner wall of the connecting tube 23. When the arc plate 27 is in a suitable position, the pulling of the arc plate 27 can be stopped. At this time, the outer wall of the positioning block 28 is engaged with the inner wall of the connecting tube 23, thereby positioning the arc plate 27 so that the arc plate 27 will not move without external force. After that, the patient bites the arc plate 27 with his teeth.

[0032] like Figure 2 , Figure 4 and Figure 5 As shown, the auxiliary mechanism 3 includes a flow control valve 31, the inner wall of the flow control valve 31 is fixedly connected to the left part of the connecting pipe 23, the left end of the flow control valve 31 is fixedly connected to a fixing ring 32, the inner wall of the fixing ring 32 is fixedly connected to the left part of the connecting pipe 23, the inner wall of the fixing ring 32 is fixedly connected to a lighting lamp 33 in a circular array, and the outer wall of the fixing ring 32 is fixedly connected to a camera 34.

[0033] Turn on the lighting 33 to illuminate the patient's mouth, then observe the current position of the nozzle 29 through the camera 34, and adjust the position of the nozzle 29 through the connecting tube 23. Each time the adjustment is made, the positioning block 28 will fix the distance of each adjustment to avoid excessive adjustment distance and damage to the patient. After that, the drug can be sprayed. When the drug circulates, it passes through the flow control valve 31, and the flow control valve 31 monitors the flow of the drug. When the flow reaches the threshold, the flow control valve 31 transmits information to stop the pump body 21 from working, thereby controlling the flow of the anesthetic drug to avoid too much or too little anesthetic drug spraying, thereby controlling the drug spraying position and the drug flow.

[0034] The working principle of the utility model is as follows: when in use, the device is adjusted according to the patient's own conditions, and the arc plate 27 is pulled to make the arc plate 27 slide on the outer wall of the connecting tube 23. At the same time, the arc plate 27 drives the positioning block 28 to move synchronously, so that the positioning block 28 moves on the inner wall of the connecting tube 23. When the arc plate 27 is in a suitable position, the arc plate 27 can be stopped from being pulled. At this time, the outer wall of the positioning block 28 is engaged with the inner wall of the connecting tube 23, thereby positioning the arc plate 27. The curved plate 27 will not move without external force. The patient then presses the curved plate 27 with his teeth, then wears the mask 24, and hangs the elastic band 25 behind the patient's ears to fix the mask 24. When wearing, the mask 24 approaches the patient's face, and the mask 24 drives the guide block 26 to slide synchronously on the inner wall of the connecting tube 23. The guide block 26 limits the mask 24, so that the mask 24 will not rotate on the outer wall of the connecting tube 23, thereby achieving a limiting effect. After the preparation work, turn on the lighting 33 to illuminate the patient's mouth, then observe the current position of the nozzle 29 through the camera 34, adjust the position of the nozzle 29 through the connecting pipe 23, and each time the adjustment is made, under the action of the positioning block 28, the distance of each adjustment will be fixed to avoid excessive adjustment distance and damage to the patient. When the position is suitable, the pump body 21 can be opened, and the anesthetic drug in the inner cavity of the volumetric bottle 1 is extracted by the hose 22, and the drug is transported to the connecting pipe 23 by the hose 22, and the drug is transported to the nozzle 29 by the connecting pipe 23, and the drug is sprayed by the nozzle 29. In this process, the drug passes through the flow control valve 31 when it circulates, and the flow control valve 31 supervises the flow of the drug. When the flow reaches the threshold, the flow control valve 31 transmits information so that the pump body 21 no longer works, thereby controlling the flow of the anesthetic drug to avoid too much or too little anesthetic drug spraying, thereby controlling the drug spraying position and the drug flow, thereby greatly improving the user experience.
