The utility model discloses an oxygen supply mask for anesthesiology, which is mainly used in scenarios where air with viruses cannot be filtered. Referring to FIGS. 1 to 4 , an oxygen supply mask for anesthesia includes a mask body 1, a fixing block 11 is fixedly connected to the inside of the mask body 1, a cleaning structure 2 is arranged inside the fixing block 11, an adjusting structure 3 for providing oxygen to the inside of the mask body 1 is arranged inside the fixing block 11, and a collecting structure 4 for collecting condensed water is arranged inside the mask body 1;

The cleaning structure 2 includes a rotating block 21, one end of the rotating block 21 is fixedly connected to a gear 22 through a connecting column, the gear 22 is meshedly connected to a rack 23, and a cleaning plate 24 is slidably connected to the side of the rack 23 away from the gear 22, the adjusting structure 3 includes a connecting rod 31, and the collecting structure 4 includes two connecting blocks 41;

The cleaning structure 2 can drive the regulating structure 3 and the collecting structure 4 respectively when moving, and the regulating structure 3 and the collecting structure 4 can adjust the oxygen content between the mask body 1 and the patient when moving.

Specifically, an elastic band is installed on one side of the mask body 1, and a slide groove 1101 is opened on the side wall of the fixed block 11, and the slide groove 1101 consists of two wedge-shaped grooves and a straight groove. An oxygen tube 12 is fixedly connected to the inside of the fixed block 11, and a collecting tube 13 is fixedly connected to the inside of the fixed block 11. The end of the oxygen tube 12 away from the fixed block 11 is connected to the air outlet end of the oxygen machine, and the end of the collecting tube 13 away from the fixed block 11 is connected to a water pump. The end of the oxygen tube 12 close to the mask body 1 is respectively connected to four water inlets, and the end of the collecting tube 13 close to the mask body 1 is connected to two water outlets.

In this embodiment, when the device is used, the mask body 1 is worn on the patient's face through an elastic band, and then the staff starts the oxygen machine and sprays oxygen evenly onto the patient's face through the water inlet at one end of the oxygen tube 12, thereby providing oxygen to the comatose patient.

In the above technical solution, in order to avoid clogging of the filter cotton 25, the detailed structure of the cleaning structure 2 is described below:

Specifically, the rotating block 21 is rotatably connected to the fixed block 11 through a connecting column, two racks 23 are symmetrically arranged along the center line of the rotating block 21, and the two racks 23 are respectively meshed with the gear 22, and two cleaning plates 24 are symmetrically arranged along the center line of the rotating block 21, and the two cleaning plates 24 are respectively slidably connected to the two racks 23, and the two cleaning plates 24 are slidably connected to the side walls of the fixed block 11.

Specifically, the filter cotton 25 is fixedly connected inside the fixing block 11 .

In this embodiment, when the device is operated for too long, in the alveoli, oxygen is transferred from the inhaled air to the blood, and the carbon dioxide in the blood is released into the alveoli and discharged from the body with the exhaled air. In this process, water will also evaporate from the blood into the alveoli and be discharged with the exhaled air. The gas exhaled by the patient can be filtered through the filter cotton 25, and the water vapor exhaled by the patient can be collected inside the filter cotton 25 to prevent the water vapor from being sprayed in the air and causing harm to the health of medical staff.

Specifically, the two sides of the two cleaning plates 24 are respectively fixedly connected with protruding columns 2401 , and the two protruding columns 2401 are respectively slidably connected to the sliding grooves 1101 .

When the gear 22 rotates, the racks 23 meshing on both sides can be driven to slide in the direction close to the gear 22. When the gear 22 slides, the cleaning plate 24 can drive the boss 2401 to slide inside the slide groove 1101. When the boss 2401 slides, it will slide according to the shape of the slide groove 1101, so that the cleaning plate 24 will slide to the side close to the filter cotton 25 after sliding one end distance. At this time, the two cleaning plates 24 will squeeze one side of the filter cotton 25. The cleaning plate 24 continues to slide to the side close to the gear 22 to discharge the water vapor filtered inside the filter cotton 25 to the bottom of the fixed block 11. At this time, the medical staff can start the air pump and then collect the water vapor through the collecting pipe 13 fixed to the air inlet pipe of the air pump. By collecting the water vapor exhaled by the patient, it is convenient for subsequent medical staff to test the water vapor, thereby observing the patient's physical health.

In the above technical solution, in order to avoid the situation of insufficient oxygen, the detailed structure of the regulating structure 3 is described below:

Specifically, the connecting rod 31 is slidably connected to the fixed block 11 , the connecting rod 31 is fixedly connected to the cleaning plate 24 , and the side of the connecting rod 31 close to the gear 22 is fixedly connected to the oxygen tube 12 .

In the present embodiment, when the two cleaning plates 24 squeeze the filter cotton 25, the movement of the cleaning plates 24 will cause the air flow between the mask body 1 and the patient's face to accelerate, thereby causing the loss of oxygen. At this time, when the cleaning plates 24 slide toward the side close to the filter cotton 25, the connecting block 41 drives the oxygen tube 12 to slide toward the side close to the filter cotton 25. When the oxygen tube 12 moves, it can drive one end close to the mask body 1, which is respectively connected to four water inlets, to slide toward the side close to the filter cotton 25. At this time, the distance between the four water inlets and the patient's face will be reduced, so that oxygen can be sprayed in a concentrated manner, avoiding the occurrence of oxygen deficiency and the like.

In the above technical solution, in order to collect the water vapor inside the filter cotton 25, the detailed structure of the collection structure 4 is described below:

Specifically, the cleaning plate 24 on the side away from the connecting rod 31 is fixedly connected to the two connecting blocks 41, the two connecting blocks 41 are fixedly connected to the end of the collecting pipe 13 close to the mask body 1 through which two water outlets are connected, and the connecting block 41 is slidably connected to the fixed block 11.

In this embodiment, when the cleaning plate 24 moves toward the side close to the filter cotton 25, it can drive the water outlet to slide toward the side close to the filter cotton 25, so that when the two cleaning plates 24 squeeze the filter cotton 25, the water vapor inside the filter cotton 25 will flow to the side of the filter cotton 25 away from the gear 22 due to its own gravity. At this time, the distance between the two water inlets and the filter cotton 25 is reduced, so that the water vapor can be collected more quickly, avoiding the water vapor being adsorbed by the filter cotton 25 again.

The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
