Creation Instructions (/ This creation is about a laryngeal mask structure, especially a convenient laryngeal mask structure that can be used in clinical medicine to allow patients to smoothly and comfortably introduce anesthetic gas. Please refer to the fifth figure and sixth As shown in the figure, the conventional laryngeal mask includes an air inlet pipe (60) and a cover body (70) installed at one end of the air inlet pipe (60). The bottom of the cover body (70) is a concave surface, the concave surface There are several openings (71), and a slightly oval-shaped inflatable ring (72) is arranged on the periphery. The rear end of the inflatable ring (72) is connected to an inflatable tube (74) with an inflatable pressure capsule (76), in which There is a valve (not shown) at the end of the air bag (76). When using a laryngeal mask, the entire body of the mask (70) is placed in the patient's throat, so that the front end of the mask (70) abuts against the esophagus, and The opening (71) is aligned with the patient's trachea, and then the valve can be self-inflated to observe the pressure capsule 6) through a syringe to send air through the inflation tube (7 4) into the inflation ring (7 2) to make the inflation ring (7 2) Expansion, so that there is no gap between the patient's throat and the cover, so that the anesthetic gas can be removed from Pipe (6 billion) enters the patient's body, would not escape from the gap bulk, while observing the pneumatic pressure bladder (76) and a retention or contraction, that may be relatively inflatable ring (72) of the inflated state. However, although the above-mentioned conventional laryngeal mask can completely allow the anesthetic gas to enter the human body, when the inflatable tube (7 4) injects 20 to 30 cc of air, the pressure of the inflated gas will be as high as 60 to 1 2 Qcm water column. This kind of pressure compresses the laryngeal mucosa for a long time, the laryngeal mucosa will ulcerate, but if the insufflation pressure is insufficient, the inflatable ring (7 2) will not be able to fully expand, and the throat and the cover.

Creation Instructions (meaning ) A-(70) creates a gap, which easily causes the anesthetic gas to escape into the esophagus, so it is not ideal for use. In addition, it can be seen from the sixth figure that the front end of the inflatable ring (72) is inflated. After it is complete, the material is made of rubber with high hardness and too thick, which will cause push-type compression on the esophagus, and even the front end of the inflatable ring (7 2) will be folded back, causing the patient to feel uncomfortable or produce The vomiting of reflex 1 cannot place the laryngeal mask in the laryngeal cavity to complete the anesthesia process On the other hand, the opening (7 1) of the cover body (70) may also be covered by the drooping pharynx to cause the air duct (60) to be blocked. Therefore, the author considers that the structure of the conventional laryngeal mask is still It is lacking, and is committed to improvement, in order to reduce or eliminate the shortcomings of the conventional laryngeal mask. Therefore, the main purpose of this creation is to provide a laryngeal mask structure that can achieve a close effect without high pumping pressure, so that the laryngeal mask is not easy to slip and Leakage will not cause discomfort to the patient. To achieve the above purpose, the technical means used in this creation include: A laryngeal mask structure, which includes: a cover with an opening at the bottom, and the periphery of the cover A soft inflatable ring is provided. The inner front end of the inflatable ring forms a guide sheet to facilitate the insertion of the laryngeal mask into the patient's throat; a son and daughter formed by the combination of an air inlet tube and an inflatable tube and communicating with the cover body through the opening Tube, one end of the inflatable tube is connected to the inflatable ring of the cover body, and the other end is separated from the air inlet tube to connect an inflatable observation device; and at least one is formed at the bottom of the cover body near the opening Ribs to guide the gas and prevent the drooping pharynx from blocking the intake pipe. 4 (Please read the precautions on the back before filling this page) · This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) Love) M240224 The first picture, the second picture, the third picture, the fourth picture, the fifth picture, and the sixth picture C7.

Creation instructions (Y) (1 2) Inside the tube 璧, one end extends in the direction of the cover (20), and the other end passes through the inlet tube (12) at a distance from the cover (20) to connect with the inlet valve (Figure (Not shown) inflatable observation device (30)The cover body (20) has an oval shape. The bottom of the cover body is a concave surface. An opening (2 2) is provided on the concave surface to communicate with the intake pipe (丄 2), and the periphery of the cover body (20) is provided with a super soft material. (Such as polyvinyl chloride (pv C)) made of inflatable ring (24), the inside of the inflatable ring (24)-a supporting guide (2 4 2) to prevent the inflatable ring (2 4) from touching The laryngeal wall is reflexed, which facilitates the insertion of the laryngeal mask into the patient's throat. The rear end of the inflation ring (2 4) is in communication with the inflation tube (i 4) of the daughter tube (i 〇), and the air can be drawn from the inflation tube ( 14) Into the inflatable ring (24). In addition, at least two longitudinal ribs (26) are formed near the bottom opening (22) of the cover body (20), which can guide the gas into the trachea and allow the patient to hang down during the anesthesia. In order to maintain the air duct (丄 2) to the patient's airway, anesthesia was performed smoothly. The inflatable observation device (30) can be a bag with a joint as shown in the figure. The automatic inflation system can blow air from the joint of the bag to adjust the degree of inflation of the inflatable ring (24). The degree of astringent or atrophic state of the pouch is relatively known about the degree of inflation of the inflatable ring (24). According to the above structure and the operating state of the fourth figure, this creation has the following advantages: μ 1 · Inflatable ring (2 4) internal front guide (2 4 design (please read the note on the back?

Creation instructions (f), so that the cover (20) will not allow the inflatable ring (2 4) to be folded back when pushed by the esophagus when it extends into the throat. Phenomenon; the inflatable ring (2 4) is made of ultra-soft material, which can also reduce the pressure on the laryngeal mucosa and avoid ulceration. 2 · Combining the inflatable tube (14) with the air inlet tube (12) to form a mother tube (10) It can avoid the trouble of adjusting the inflation tube (7 4) when inserting the larynx when using a laryngeal mask. 3 · At the bottom of the cover (2 0) The design of the ribs (2 6) can easily guide the gas into the trachea, and it can also stand against the pharynx, so that the patient can still maintain the airway patency under unconscious conditions. In summary, this creation can indeed solve the problem caused by the conventional laryngeal mask. Discomfort and operational problems The structure is simple and light, and the method of use is easy. 'It can be easily used even by people who do not have multiple medical experiences, and it is more convenient to use. In addition,' this creation is a novel creation not seen in the market, and it also has medical aspects. The practical design of the application should meet the application requirements of the new patent, and the application should be submitted in accordance with the law.
