[0002] An anesthesia face mask is a medical first-aid device used in conjunction with an anesthesia machine and a ventilator. It is used to deliver anesthetic gas for the patient to inhale during anesthesia. It is mainly used for anesthesia respiratory resuscitation and surgery, which can reduce the pain of patients, especially infants and young children, during the operation and enable the operation to proceed smoothly. Currently, the anesthesia face masks used for general anesthesia induction and first-aid resuscitation of patients in clinical practice include a mask body, an air inlet at the upper end of the mask body, and an annular closed mask airbag provided at the lower end of the mask body. When the anesthesia face mask is buckled on the patient's mouth and nose, it is necessary to press the balloon to introduce oxygen.

[0003] In the prior art, after gas anesthesia of the patient is completed, since the patient is under general anesthesia and it is difficult for the patient to breathe independently, oxygen supply must be provided to the patient at this time. Usually, the anesthesiologist removes the anesthesia face mask and inserts a laryngeal mask for continuous oxygen supply to the patient. This operation process requires more than two people to complete. The anesthesiologist needs to continuously press the anesthesia face mask on the patient's mouth and nose, and then another person needs to press the balloon for operation. It cannot be operated by a single person. Moreover, in order to ensure the airtightness of the anesthesia face mask, it is necessary to continuously press the anesthesia face mask, which consumes a large amount of physical strength of the anesthesiologist. Summary of the Utility Model

[0004] Based on this, in view of the above technical problems, it is necessary to provide an anesthesia face mask that can control the elongation or contraction of the first strap and the second strap by inflating or deflating the inner cavities of the first strap and the second strap, so as to facilitate quickly fixing the mask shell on the patient's mouth and nose and facilitating the operation to release the fixation.

[0028] To enable those in the technical field to better understand the solution of the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] As described in the background art, an anesthesiologist needs to continuously press the anesthesia mask against the patient's mouth and nose, and then another person needs to operate by pressing the balloon. It cannot be operated by a single person, and in order to ensure the tightness of the anesthesia mask, the anesthesia mask needs to be continuously pressed, which consumes a large amount of physical strength of the anesthesiologist.

[0030] Specifically, please refer to Figures 1 to 5 , an anesthesia mask, which includes:

[0031] A mask housing 1, with an interface 2 installed at the upper end of the mask housing 1 for externally connecting an oxygen tube;

[0032] A first strap 4 and a second strap 5, with the ends of the first strap 4 and the second strap 5 both fixed to the outer wall of the mask housing 1. The first strap 4 and the second strap 5 are both composed of a telescopic tube 11 and a contraction cord 12, and the contraction cord 12 is fixed to the side wall of the telescopic tube 11 along the axis of the telescopic tube 11.

[0033] For an anesthesia mask provided by the present utility model, when the mask housing 1 is buckled on the patient's mouth and nose, before putting the first strap 4 and the second strap 5 on the patient's head, by inflating the telescopic tubes 11 of the first strap 4 and the second strap 5, the telescopic tubes 11 expand and become longer, facilitating putting the first strap 4 and the second strap 5 on the patient's head. After the first strap 4 and the second strap 5 are put on, the gas in the telescopic tubes 11 is released. At this time, the contraction of the contraction cord 12 drives the telescopic tubes 11 to contract, thereby controlling the tightening of the first strap 4 and the second strap 5, quickly binding the mask housing 1 to the patient's mouth and nose, and continuously fixing it. Therefore, by inflating or deflating the inner cavities of the first strap 4 and the second strap 5, the purpose of controlling the elongation or contraction of the first strap 4 and the second strap 5 is achieved, facilitating quickly fixing the mask housing 1 to the patient's mouth and nose and facilitating the operation to release the fixation.

[0034] To enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings.

[0035] It should be noted that, without conflict, the embodiments and the features and technical solutions in the embodiments in the present utility model can be combined with each other.

[0036] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. Embodiment

[0037] Please refer to Figure 1 , an anesthesia mask, with an interface 2 installed at the upper end of the mask housing 1 for externally connecting an oxygen tube, and oxygen is supplied to the mask housing 1 through an oxygen generator or an oxygen bag.

[0038] It is worth mentioning that, as Figures 1 to 3 shown, the ends of the first strap 4 and the second strap 5 are both fixed to the outer wall of the mask housing 1. The first strap 4 and the second strap 5 are both composed of a telescopic tube 11 and a contraction cord 12, and the contraction cord 12 is fixed to the side wall of the telescopic tube 11 along the axis of the telescopic tube 11. By inflating the inner cavity of the telescopic tube 11, the telescopic tube 11 and the contraction cord 12 are stretched, and when the gas in the telescopic tube 11 is released, the elastic force of the contraction cord 12 is used to fix the telescopic tube 11 to fit the patient's head, facilitating fixing the mask housing 1 to the patient's head.

[0039] In addition, as shown in Figure 2 and Figure 4 , the retractable cord 12 is installed on the inner wall of the telescopic tube 11, and the retractable cord 12 is fixed to the telescopic tube 11 through a number of positioning points, facilitating the retractable cord 12 to extend when the telescopic tube 11 extends, and the retractable cord 12 contracts to drive the telescopic tube 11 to contract. The telescopic tube 11 is of a cylindrical structure or a flat structure, and an inflation cavity is provided in the middle of the telescopic tube 11 to better fit the patient's head.

[0040] In this embodiment, as shown in Figure 1 , an airbag 3 is installed on the outer ring of the opening of the interface 2, which can fit the patient's face. The outer rings of the first strap 4 and the second strap 5 are covered with a flannel layer, making the patient's head more comfortable. Embodiment

[0041] A further optimization is made to the anesthesia mask provided in Embodiment 1. Specifically, as shown in Figure 1 and Figure 4 , the first strap 4 and the second strap 5 are connected through a communicating pipe 7. A control valve 10 is installed at the input end of the communicating pipe 7. By inflating the communicating pipe 7, the first strap 4 and the second strap 5 are controlled to extend, and by controlling the control valve 10, the gas in the first strap 4 and the second strap 5 is discharged to control the shortening of the first strap 4 and the second strap 5.

[0042] It is worth mentioning that, as shown in Figure 5 , a gas guide pipe 8 is connected to the output end of the communicating pipe 7. The input end of the gas guide pipe 8 extends into the inner cavity of the interface 2. When oxygen is filled into the interface 2, the gas can enter the communicating pipe 7 through the gas guide pipe 8, and whether the gas is discharged is controlled by controlling the control valve 10.

[0043] Preferably, as shown in Figure 1 , both ends of the first strap 4 and the second strap 5 are connected to the communicating pipe 7, which can control the extension and shortening of the first strap 4 and the second strap 5 simultaneously.

[0044] In this embodiment, as shown in Figure 5 , the control valve 10 is installed in the gas guide pipe 8, and the control knob 6 located on the control valve 10 extends to the outside of the interface 2, facilitating driving the control valve 10 to rotate by controlling the control knob 6 to control the connection of the gas guide pipe 8. A one-way valve 9 is installed at the input end of the gas guide pipe 8. By installing the one-way valve 9, oxygen enters the gas guide pipe 8 unidirectionally to avoid air leakage during the binding process, and the gas can be controlled to flow out through the side of the gas guide pipe 8 by rotating the control valve 10.

[0045] The usage process of an anesthesia mask provided by the present utility model is as follows: When buckling the mask shell 1 on the patient's mouth and nose, before putting the first strap 4 and the second strap 5 on the patient's head, by inflating the telescopic tubes 11 of the first strap 4 and the second strap 5, the telescopic tubes 11 expand and become longer, which is convenient for putting on the patient's head. After the first strap 4 and the second strap 5 are put on, the gas in the telescopic tubes 11 is released. At this time, the contraction ropes 12 contract to drive the telescopic tubes 11 to contract, thereby controlling the first strap 4 and the second strap 5 to tighten, quickly binding the mask shell 1 on the patient's mouth and nose, and maintaining the fixation.
