Description

Technical Field

[0001] The utility model belongs to the technical field of medical accessories, and in particular relates to an anti-falling laryngeal mask. Background Art

[0002] At present, fiberoptic bronchoscopy is a means of diagnosing respiratory system diseases. The method of first inserting a standard laryngeal mask under intravenous anesthesia and then inserting a fiberoptic bronchoscope through the laryngeal mask for examination has been widely used in clinical practice.

[0003] The existing authorized public number is CN207734436U, which discloses a laryngeal mask that solves the problem of laryngeal masks in the prior art being difficult to insert into the patient's throat. The key points of its technical solution are a laryngeal mask comprising a cuff, a laryngeal tube, and an inflation tube connected to the cuff. The laryngeal tube is provided with a hollow fixed joint at the end away from the cuff. The fixed joint is detachably provided with a laryngeal tube fixing member that limits the bending range of the laryngeal tube. The laryngeal tube fixing member is made of a hard material. The laryngeal tube fixing member includes an arc-shaped fixed rod inserted into the laryngeal tube and having an outer diameter smaller than the inner diameter of the laryngeal tube, and a fixed baffle connected to the end of the arc-shaped fixed rod away from the laryngeal tube and abutting against the fixed joint. The laryngeal mask has a laryngeal tube fixing member that limits the bending range of the laryngeal tube so that the laryngeal tube of the laryngeal mask can be inserted into the patient's throat. However, the above-mentioned laryngeal mask has a relatively simple structure and does not have a limiting structure, so that the overall structure is easy to fall off when in use and has poor stability. Therefore, it is necessary to provide a laryngeal mask that prevents falling off to solve the above-mentioned problem. Utility Model Content

[0004] The technical content of the utility model is to provide an anti-falling laryngeal mask.

[0005] In order to solve the above problems, the present invention provides an anti-falling laryngeal mask, comprising: a mask body, the outside of the mask body is fixedly connected to a connecting head, and the outside of the connecting head is rotatably connected to a throat tube; a limiting component, the limiting component includes two threaded sleeves, and the two threaded sleeves are fixedly connected to the outside of the mask body. First, the mask body is placed in a suitable position on the user's neck, and then the threaded head is rotated to make its threads clamped with the inside of the threaded sleeve, so that the entire ring tube can be sleeved on the user's neck, so that the mask body is firmly limited. During the limiting process, by pressing the pressurization bag, external gas can enter the inside of the ring tube through the connecting tube, and finally the expansion ring is expanded, so that when used by people of different physiques, the mask body can be more closely fitted to the neck when limited.

[0006] As a further solution of the present invention, the limiting assembly also includes two threaded heads, which are respectively rotatably connected to the inside of the two threaded sleeves, and the outsides of the two threaded heads are jointly movably connected to a ring tube. The threaded heads can be clamped in the inside of the threaded sleeve by rotating the thread, thereby further realizing the limitation of the entire ring tube.

[0007] As a further solution of the present invention, an expansion ring is fixedly connected to the outside of the ring tube, and a flocking layer is provided on the outside of the expansion ring. The expansion ring can be inflated to expand so that the ring tube can be completely mounted on the neck, further realizing the limitation of the mask body, and can be used by people of different physiques.

[0008] As a further solution of the present invention, the expansion ring is communicated with the interior of the ring tube, and the expansion ring can change with the change of the air pressure inside the ring tube.

[0009] As a further solution of the present invention, an air intake pipe is fixedly connected to the outside of the annular tube, and a sealing ring is provided inside the air intake pipe. The air intake pipe allows external air to enter the interior of the annular tube.

[0010] As a further solution of the present invention, a pressure relief valve is provided on the outside of the air inlet pipe, and the pressure relief valve can control the entry and exhaust of air inside the annular pipe.

[0011] As a further solution of the present invention, a connecting pipe is provided on the outside of the air intake pipe, and a pressurizing bag is fixedly connected to the end of the connecting pipe. The pressurizing bag can be pressed repeatedly to allow external air to enter the interior of the annular pipe through the connecting pipe.

[0012] As a further solution of the present invention, the connecting tube is a spiral telescopic tube, and the connecting tube is elastic and can be telescopic.

[0013] In summary, the present invention has at least the following beneficial technical effects:

[0014] First, the utility model records that the mask body is first placed at a suitable position on the user's neck, and then the thread head is rotated to clamp the thread with the inside of the thread sleeve, so that the entire ring tube can be placed on the user's neck, so that the mask body is firmly limited.

[0015] Second, the utility model records an anti-falling laryngeal mask, which records that during the limiting process, by pressing the pressurized bag, external gas can enter the interior of the ring tube through the connecting tube, and finally the expansion ring can be expanded, so that when people of different physiques use it, the mask body can be limited to fit the neck more closely.
