Description

Technical Field

[0001] The utility model relates to the technical field of anesthesia, in particular to an anesthesia atomizer mask. Background Art

[0002] When anesthesia is performed in the hospital, the anesthesia machine and nebulizer are connected by a threaded tube and used together. Nebulizers are of oral and mask types. For some young people or people who are prone to stress reactions such as hyperactivity, mask-type nebulizers are more convenient to use because they are easy to fix and do not require active oral placement.

[0003] When the nebulizer is actually used clinically, in order to attract the wearer's attention and enable them to use the nebulizer in conjunction with it, induction and soothing balloons are currently added to the design. For example, the Chinese patent document with application number CN202022354759.3 discloses a soothing pediatric anesthesia mask, which fixes the soothing balloon on one side of the mask body, and uses the cartoon image on the soothing balloon or the soothing balloon itself to attract the child's attention. The soothing balloon can be blown up through the mask body, so that the child can adapt to wearing the mask body to the mouth and nose during play, which is beneficial for medical staff to perform anesthesia work in the later stage. However, the defect of this solution is that it only uses a mask similar to a mask nebulizer in the early stage to make it easier for the later wearer to accept the effect of a real mask, and it cannot attract and soothe the wearer while using a real mask.

[0004] To solve the above technical problems, the Chinese patent document with application number CN202123273548.8 discloses a pediatric anesthesia induction mask, which can be connected to an anesthesia machine through a three-way connector and a threaded tube, and at the same time, a balloon can be blown by an inflatable expansion component to relieve the nervousness of the child, and the child will take a deep breath actively after blowing the balloon, which effectively improves the child's inhalation induction speed and facilitates anesthesia induction. However, a defect of this solution is that after the child blows the balloon, the exhaled gas is easy to flow back into the mask. One of the reasons is that after blowing, it is necessary to inhale again after blowing, and gas reflux is easy to occur from the blowing port during inhalation. Another reason is that the balloon will shrink due to pressure, which requires frequent adjustment or removal of the balloon by switching valves, otherwise the exhaled gas in the balloon will flow back into the mask, which will seriously affect the use effect of the mask. Therefore, an efficient anesthesia mask is needed that can prevent gas from flowing back into the mask and facilitate the adjustment of the blown gas flow rate. Utility Model Content

[0005] In order to overcome the defects of the prior art, the technical problem to be solved by the utility model is to propose an anesthesia nebulizer mask, which can attract and soothe the wearer while using the mask, and can more efficiently induce inhalation of the wearer to improve the use effect of the mask.

[0006] To achieve this purpose, the utility model adopts the following technical solutions:

[0007] The utility model provides an anesthesia nebulizer mask, including a mask body, wherein the mask body is provided with an air inlet near the chin when worn, the air inlet is provided with a connecting pipe, an air blowing port is provided near the mouth when worn, the air blowing port is provided with an air blowing pipe integrally formed with the mask body, and a callback mechanism is also provided on the air blowing pipe. During anesthesia, the connecting pipe is connected to the anesthesia machine through a threaded pipe. In this way, the gas flow rate can be adjusted through the callback mechanism and the gas backflow can be prevented during inhalation; further, the mask body is provided with a flexible pad along the edge near the face side when worn to ensure comfortable wearing; the mask body is also provided with a tightening belt to facilitate fixing.

[0008] The preferred technical solution of the utility model is that the callback mechanism includes an anti-backflow structure, which includes at least two stopper sheets, at least two of which are arranged in a funnel shape, and at least two of which are in conflict with each other at one end close to the air outlet of the blowing tube, and the other end is integrally formed with the inner wall of the blowing tube; further, the callback mechanism also includes an adjustment seat, and the blowing tube is provided with an adjustment groove that cooperates with the adjustment seat between the anti-backflow structure and the air outlet of the blowing tube, the adjustment seat is provided with an air vent that cooperates with the blowing tube, and the air release hole that cooperates with the air vent is provided on the blowing tube. During anesthesia, the position of the air vent is adjusted by rotating the adjustment seat to control the gas flow.

[0009] An optimal technical solution of the utility model is that a detachable balloon is arranged at one end of the air blowing tube away from the mask body, and a fixing groove is arranged at the air outlet end of the air blowing tube to facilitate the fixing and replacement of the balloon.

[0010] The beneficial effects of the utility model are:

[0011] The utility model provides an anti-backflow structure and an adjustment seat to ensure that when the wearer inhales after blowing, there will be no backflow of gas from the air blowing tube. At the same time, the gas flow rate can be adjusted by rotating the adjustment seat, so that the wearer can take a deep breath when inhaling to increase the induction speed during inhalation. At the same time, a balloon can be arranged at the air outlet end of the air blowing tube to relieve the tension of the wearer. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0019] Embodiment 1: As shown in the figure, an anesthesia nebulizer mask includes a mask body 1. When the mask body 1 is worn, an air inlet 101 is provided near the chin. The air inlet 101 is provided with a connecting tube 11. When the mask body 1 is worn, an air blowing port 102 is provided near the mouth. The air blowing port 102 is provided with an air blowing tube 12 integrally formed with the mask body 1. The air blowing tube 12 is also provided with a callback mechanism 13. During anesthesia, the connecting tube 11 is connected to the anesthesia machine through a threaded tube. When the nebulizer mask of this example is in use, the anesthesia machine is connected to the air inlet 101 through the connecting tube 11, and the user blows air through the blowing port 102. Then, during the blowing process, the blowing flow rate is adjusted by the callback mechanism 13 and the gas backflow during inhalation is prevented. Specifically, in order to adjust the flow rate and direction during blowing, the callback mechanism 13 includes an anti-backflow structure 131, and the anti-backflow structure 131 includes at least two stopper sheets 1311. The at least two stopper sheets 1311 are arranged in a funnel shape. At least two stopper sheets 1311 are in contact with each other at one end close to the balloon 14, and the other end is integrally formed with the inner wall of the blowing tube 12; in this way, the wearer can blow air normally, while the funnel-shaped structure composed of at least two stopper sheets 1311 can prevent the gas from flowing back into the mask; further, the callback mechanism 13 also includes an adjustment seat 132, and the blowing tube 12 An adjusting groove 133 cooperating with the adjusting seat 132 is provided between the anti-backflow structure 131 and the balloon 14, a vent 1321 cooperating with the blowing tube 12 is provided on the adjusting seat 132, and a leaking hole 1331 cooperating with the vent 1321 is provided on the blowing tube 12. During anesthesia, the position of the vent 1321 is adjusted by rotating the adjusting seat 132 to control the gas flow rate. In this way, during the blowing process, the adjusting seat 132 can be rotated to align the vent 1321 with the leaking hole 1331 or the vent 1321 with the air outlet of the blowing tube 12, so that normal blowing can be performed. At the same time, the cross-sectional area of ​​the vent 1321 aligned with the leaking hole 1331 can be adjusted, that is, when the aligned area is smaller, the wearer will blow harder, so that a deep breath will be taken when inhaling, which greatly increases the induced speed during inhalation. Furthermore, the mask body 1 is provided with a flexible pad 15 along the edge near the face side when worn to ensure comfortable wearing; at the same time, a tightening belt 16 is also provided on the mask body 1 to facilitate fixation.

[0020] Embodiment 2: The difference from Embodiment 1 is that a detachable balloon 14 is provided at one end of the air blowing tube 12 away from the mask body 1, and a fixing groove 121 is provided at the air outlet end of the air blowing tube 12 to facilitate the fixing and replacement of the balloon 14; when using this scenario, there is no need to align the air vent 1321 with the air outlet of the air blowing tube 12, so that the gas can still flow out from the air leakage hole 1331, so that the blown gas is mainly used to blow the balloon 14, and then when inhaling, the gas in the balloon 14 can flow out from the air leakage hole 1331, that is, the balloon 14 can be automatically deflated to reduce the volume, and there is no need to frequently deflate, and it is also more attractive.

[0021] The present invention is described by preferred embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. The present invention is not limited to the specific embodiments disclosed herein, and other embodiments falling within the claims of this application are within the scope of protection of the present invention.
