The invention relates to the field of medical equipment, namely to laryngeal masks.

Over the years the use of laryngeal mask has established itself as a safe duct, rarely leads to complications. Primary laryngeal mask /LM/ was used for planned operations in patients without the risk of regurgitation.

But now LM has become so popular that its scope is expanding continuously. LM included in the standards when difficult intubation in many countries. Thus, the LM has been applied and emergency patients at risk of regurgitation. This fact leads to the need for a more secure mask against regurgitation and aspiration. The mass use of laryngeal mask dictates the need to use nerazdvoimy cuff to prevent risk of the patient associated with improper inflation of the cuff or insufficient current control of the pressure inside the cuff during General anesthesia.

To solve problems with regurgitation created mask with nerazdvoimy cuff on patent RU 02366463. Since the publication of this patent came with a lot of patents masks with nerazdvoimy cuff and a relatively large gastrorenal, however, such masks are of considerable size vozduhovodnom drainage part in comparison with the dimensions of the sealing cuff that will certainly complicate the installation of such masks. The objective of this patent is the solution to the problem of regurgitation using easily and quickly installed mask with nerazdvoimy cuff, large gastrorenal and with the ability not only to withdraw the contents from the stomach to the probe, but also the simultaneous discharge of gastric contents or gases from the proximal portion of the mask out of his mouth.

To solve aspiration and regurgitation, you must solve the problem of adequate drainage of the stomach cavity with the ability to simultaneously delete the contents of the stomach, which can rise between the probe and the walls of the esophagus. To this end, the following devices described in the patents.

In patent WO 2012127436 described laryngeal mask with nerazdvoimy cuff, which can simultaneously remove the contents of the stomach probe and esophageal funnel on the second gastrorrhagia hole, however, point out gastrodiae are not on the Central line, and on each side, which is extremely difficult installation of a gastric probe.

In the patent US 20130125897 described sophisticated laryngeal mask with nerazdvoimy the cuff. The height vozduhovodnom drainage part is clearly more than 50% of the maximum height of the sealing cuff. For ease of installation there is a special method that modifies the configuration of the ger is eitherwise cuff. In one embodiment, the mask includes a small diameter gastrodine. The connector is located along the respiratory channel.

In patent WO 2013182457 described variants mask with nerazdvoimy the cuff. The connector is located along the respiratory channel. The height vozduhovodnom drainage part is about 50% of the maximum height of the sealing cuff and the diameter of gastrodiae - about 17% of the maximum height of the sealing cuff. In addition, with the introduction of the probe into the stomach it will cover the whole cross-sectional area of gastrodiae, it becomes unlikely the opportunity of the discharge of gastric contents or gases from the proximal portion of the mask out of his mouth.

Mask with nerazdvoimy cuff and adequate diameter gastrorenal channel is a mask for patent RU 02366463. She was selected as a prototype.

Description of the prototype device includes a cuff in the form of a sealing ring formed of u-shaped rim, which can be opened or to the side of the breathing channel, or in the opposite direction, and a part of gastrodiae, with the plane of the sealing ring with one hand closed shell. Device: with the introduction of gastrodiae special Introducer cuff changes the configuration, significantly uploas that facilitates the introduction of the mask.

p> The disadvantages of this mask, in that changing the configuration of the mask due to the introduction and removal of Introducer slows down the process of its installation, vozduhovodnom drainage of the mask sufficiently large diameter, which complicates the installation of the mask, in addition, when a spasm of the masticatory muscles of the patient is possible clamping of the respiratory channel.

These drawbacks are eliminated in the invention.

The objective of the invention is to provide a laryngeal mask, which allows you to adequately drain the stomach, allowing the safe passage of gastric contents from both stomach and esophagus out of his mouth, quickly and easily installed without Introducer, vozduhovodnom drainage of the mask will be the most compact, however, allowing adequate probe into the stomach, at the same time constantly leaving gaping additional drainage channels for the smooth discharge of gastric contents, having risen esophagus between the walls of the esophagus and of the probe, while this prevented the possibility of cutting (squeezing) the teeth of the patient airway channel mask.

This and other problems are solved in the inventive laryngeal mask with improved geometric configuration.

As will become clear from the description of the invention, it may be different in the options and some of the details may be modified in various respects, without leaving the scope of the invention. Accordingly, the drawings and description should be considered illustrative materials that do not have restrictive values, taking into account the fact that the scope of the claims defined in the claims.

The problem is solved in that in the present us the cuff device in the form of a sealing ring formed of u-shaped rim and flattened part of broadband gastrodiae opening in the esophagus, with horseshoe-shaped bezel can be opened either to the outside or towards the respiratory tract. Horseshoe-shaped rim has a wall adjacent to gastrodiae, thinner than the other, thus, when exposed to the o-ring forces in the direction of gastrodiae wall adjacent to gastrodiae, easily SAG with minimum deformation of the remaining elements of the mask, the shape of the cuff is flattened, facilitating the introduction of the laryngeal mask in a patient's body.

The drainage channel is open at one end in esophageal funnel and the other end is directed to the outside of the mouth.

The device further comprises a structural element that prevents cutting (clamped) respiratory canal teeth of the patient in the form of thickening of the walls of the respiratory channels. This structural element can be additionally reinforced with reinforcing elements as tubes of different profiles or spirals. Respiratory canal passes through vozduhovodnom drainage of the mask and connects the connector of the mask and the inner part of the sealing cuff, carrying out breathing mixture to the larynx of the patient.

Vozduhovodnom drainage of the mask on the cut forms an oval, a part of which, which is the segment of the oval is gastrodiae, and the other part contains two respiratory channel, made in the form of segments of an oval, inscribed in the oval vozduhovodnom drainage parts of the mask and separated by partition walls between themselves and between gastrorenal channel.

While the claimed laryngeal mask quickly and easily installed without the use of Introducer.

In the use of this LM is achieved following a new technical result:

freely removed gastric contents out of the mouth when in the stomach, the large diameter probe, not only from the stomach, but also from the funnel of the esophagus at the same time due to the constantly yawning additional channels formed in the corners of the drainage channel during installation of the gastric probe;

mask quickly and easily installed without Introducer;

- vozduhovodnom drainage of the mask made the most compact;

- prevented the possibility of cutting (squeezing) the teeth of the patient airway channel mask.

The proposed device has gastrodine in the form of a segment of a circle in cross section, through the introduction of the gastric probe formed two additional constantly yawning channel for lead free out of the mouth of gastric contents from the spout of the esophagus.

The duct is divided into 2 channels, between which there is a partition that prevents accidental kinking or compression when twisting and bending the AI vozduhovodnom drainage parts of the mask, in conjunction with the curve (smoothing) of the corners of the cross-section of the respiratory channel ensures free passage of the breathing gas to the lungs of the patient when the angle of inclination of the neck and turn the patient's head.

At the time of installation of the u-shaped rim is pressed against gastrodiae, optimizing the shape of the sealing cuff for easy introduction of the device into the patient. After passing over the tongue shaped bezel gets in a natural extension of the hypopharynx and under the influence of elastic forces restores form, optimizing it for the best of Hermeticism connection system patient - laryngeal mask.

The invention is accompanied by drawings, where

in Fig.1 shows a General view LM, Fig.2 shows part of the mask of Fig.3 shows a section of the mask on the level of structural elements that prevent compression of the airway channel, without reinforcing inserts with reinforcing inserts of Fig.4 - transverse incision at the level of vozduhovodnom drainage part without the injected probe and with the probe of Fig.5 is a transverse incision at the level of the sealing cuff (mask option when u rim is open to the respiratory channel), Fig.6 - transverse incision at the level of the sealing cuff (mask option when u rim is open to the outside).

p> Laryngeal mask contains: connector 1; structural elements that prevent compression of the breathing channel 2; vozduhovodnom and drainage part 3; laryngeal part of the mask 4; an elastic u-shaped rim (Fig.2 bold dotted line) 5, (part of gastrodiae) forms a sealing cuff in the form of a sealing ring 6; gastrorenal channel (Fig.2 the walls of the channel shown in bold lines) 7 ending gastrorenal hole 8; gastric tube (not part laryngeal mask, but can be installed in gastrorenal channel) 9; respiratory channel 10; a reinforcing insert (not a required element) 11; supplementary constantly yawning channels 12.

All parts of the LM (with the exception of reinforcing inserts into the structural element that prevents compression of the airway channel, if applicable) are cast simultaneously and represent the monolith. It is economically very important advantage of the invention.

The device is used as follows.

Horseshoe-shaped rim 5 press to gastrodine 7, while the transverse dimensions of the sealing cuff 4 is reduced.

The device is inserted through the mouth of the patient until it stops in the upper esophageal sphincter (sphincter). When this drain hole 8 is located at the level of werhner the esophageal sphincter and directed into the esophagus. The back side of the laryngeal side of the mask formed gastrorenal channel, adjacent to the back of the throat. Horseshoe-shaped rim 5 encircles the throat on each side and from the root of the tongue.

When setting the mask in the patient's body after passing through the narrow channel formed by the root of the tongue, sealing cuff falls within the zone of expansion of the channel and under the spring action of the elastic forces of the polymer (seeking to buy its original shape) horseshoe-shaped rim 5 extends, filling the anatomical extension of the hypopharynx.

When this drain hole 8 is located at the level of the upper esophageal sphincter and directed into the esophagus. Drainage hole 8 (as well as broadband, gastrodine 7) through and through it is free to depart gastric contents in the event of regurgitation. To the back of the throat turned back astrotraining channel.

The connector 1 of the device is at right angles to the tidal channel and, if you plan to IVL, when connecting the mask to the breathing circuit apparatus outside covers attached tee breathing circuit without using an additional angle adapter. Through broadband, gastrodine you can spend adequate probe 9 in the stomach for active or passive UD the population of gastric contents, in the corners of the drainage channel mask is formed more constantly yawning channels 12 for discharge of the gas or liquid (which may rise to the level of the upper esophageal sphincter between the probe and the wall of the esophagus because of reverse peristalsis of the esophagus or due to obstruction of the drainage holes of the gastric probe solid particles of gastric contents) out of the mouth. Stomach contents from the esophagus can freely penetrate into the gaping channels, since the cross-sectional area of the drainage holes 8 more cross-sectional area of the probe 9, is inserted through gastrodine 7 in the stomach. Thus, between the outer wall of the gastric probe 9 and the edge astrotraining holes 8 there is a gap, through which the stomach contents from the esophagus penetrates into the gaping channels 12 in the corners astrotraining channel 7.

Declare laryngeal mask relates to a device of relatively simple and inexpensive to manufacture. The low cost of manufacturing this device allows you to use it as disposable. Declare laryngeal mask safe for the patient and can be used effectively in clinical practice.
