Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a multifunctional laryngeal mask airway. Background Art

[0002] The laryngeal mask airway (LMA) is a commonly used artificial airway in modern clinical practice, particularly in emergency resuscitation and general anesthesia. Its primary function is to maintain airway patency and ensure patient ventilation and oxygenation. The LMA consists of two parts: the ventilation tube and the ventilation mask. The ventilation tube, similar to a regular trachea, is made of silicone. One end is open for connection to an anesthesia machine or ventilator, while the other end connects to the ventilation mask. The ventilation mask forms an airway in the larynx. It is oval-shaped, made of soft rubber, with raised edges and an internal cavity. At the connection between the ventilation tube and the mask, the incline of the tube is 30°. A black line at the back of the ventilation tube helps identify any twisting. Above the inlet of the ventilation tube into the mask, two vertical barriers create several longitudinal slits to prevent epiglottic obstruction of the lumen. The proximal end of the mask connects to an injection tube, which inflates the mask by injecting air.

[0003] During the use of existing laryngeal mask airways, some fluid may accumulate in the patient's larynx. If this fluid is not removed in time, it can easily cause choking on the patient's airway. In addition, the existing laryngeal mask airways are relatively large, which can easily cause airway damage to the patient when they are inserted into or removed from the airway.

[0004] Therefore, those skilled in the art have provided a multifunctional laryngeal mask airway to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a multifunctional laryngeal mask airway to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional laryngeal mask airway tube, including an airway tube and a support for insertion into the larynx, the support including a support body, a recess on the outer side of the support body, an airbag on the outer side of the recess, and two stretchable soft pads on the support body, the two soft pads being connected to the airbag.

[0007] Preferably, the support body is hollow inside, a connecting cover is provided inside the support body, one end of the air guide tube is fixed on the connecting cover, and a ventilation tube communicating with the airbag is provided on the air guide tube.

[0008] Preferably, the support body is provided with a vertical fence on one side of the connecting cover, and the inside of the air duct is provided with a drug delivery tube for introducing anesthetic, one end of the drug delivery tube extending into the inside of the connecting cover.

[0009] Preferably, the support body is provided with multiple drainage holes.

[0010] Preferably, the support body has a collection chamber divided by a partition, the drainage hole is connected to the collection chamber, and the partition is provided with a liquid extraction tube connected to the collection chamber.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. In this utility model, the airbag connected by the soft pad is fitted onto the recessed part of the support body. After the airbag is inflated, it expands and enlarges. The expanded airbag can fill the gap between the larynx and the support body, which can prevent the backflow of fluid in the larynx and prevent the patient from being choked by the fluid.

[0013] 2. In this utility model, the airbag is located on the outside of the concave part. The airbag is used to replace the traditional laryngeal mask airway. After the airbag is inflated, it can be expanded, which can avoid damage to the patient's trachea caused by the excessive size of the traditional laryngeal mask airway. Attached Figure Description

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] In this design, all structures are made of materials that meet medical standards.

[0020] Please see Figures 1-3In this embodiment of the present invention, a multifunctional laryngeal mask airway includes an air tube 1 and a support for insertion into the larynx. The support includes a support body 2, a recess 3 on the outer side of the support body 2, an airbag 4 on the outer side of the recess 3, and two stretchable soft pads 5 on the support body 2, which are connected to the airbag 4.
