The technical field to which the present invention

The present invention relates to vozduhovodnom devices used to facilitate lung ventilation in patients who are unconscious, in particular to such devices of this kind, which are designed for placement above the orifice of the larynx of the patient in order to prevent airway obstruction and ensure spontaneous or forced pulmonary ventilation.

Description of the prior art

To maintain open airway the patient lying unconscious under the influence of General anesthesia, usually use a flexible endotracheal tube, made of rubber or plastic, which is injected, moving down through the trachea. Known endotracheal tube often include filled tracheal cuff, located symmetrically around the front end of the endotracheal tube, that is, in the end, which is inserted into the trachea. This filled the tracheal cuff is used to seal and to secure the endotracheal tube in place.

Usually an endotracheal tube inserted through the mouth or nose and the larynx into the trachea, then the tracheal cuff is filled through a small auxiliary tube in order to obtain the seal relative to the wall fuck the I. The introduction of the endotracheal tube into the trachea of the patient is an operation requiring high qualifications, which typically use a laryngoscope, which control the passage of the endotracheal tube through the larynx behind the vocal cords into the trachea. Some patients enter an endotracheal tube in the trachea is difficult or even impossible. In addition, with the introduction of the endotracheal tube there is a serious risk of damage to soft tissues or the larynx. In addition, there is a risk of accidental, but very undesirable introduction of the endotracheal tube into the esophagus or into the right or left main bronchus.

Instead incubating tubes to maintain respiratory tract of a patient lying unconscious under the influence of General anesthesia, you can use oropharyngeal (oropharyngeal or nasopharyngeal (nasal) vostokovedenie device. Oropharyngeal or nasopharyngeal vostokovedenie the device is a flexible tube, which is injected from your mouth (oropharyngeal vostokovedenie device) or nose (nasopharyngeal vostokovedenie device) of the patient in his throat, but not in the larynx. Usually oropharyngeal or nasopharyngeal vostokovedenie device used in conjunction with a face mask mounted on the mouth or nose of the patient, unlike incubat the Onna tube, normally used without face masks. Although primenenii oropharyngeal and nasopharyngeal vostokovednyh device is provided to prevent obstruction of the airway of the patient's language, such devices cannot be used for forced ventilation of the lungs of the patient, moreover, in their application, there is no risk of inhalation of foreign substances (aspiration). For these and other reasons, the use of devices of this type in many cases is undesirable.

In known from the prior art vostokovednyh devices (see, for example, U.S. patents NN 4.509514; 4.995.388; 5.241.956; 5.249.571; 5.282.464; 5.297.547; 5.305.743; 5.355.879; 5.584.290; 5.632.271 and 5.682.880, issued in the name of Archibald hay. Jay. The brain (Archibald I. J. Brain), collectively referred to as the "patents of the Brain") is used curved tube and laryngeal mask segment located at one end of this tube. Mentioned laryngeal mask segment includes a flexible annular inflatable ring, set with a fit to the inner wall of the laryngeal mask segment. Laryngeal mask segment previously given some ellipsoidally shape corresponding to the shape of the cavity of the respiratory tract beyond the larynx, so that the laryngeal mask segment forms a seal on the periphery of the inlet of the larynx without penetration Hort is neither. The above-mentioned curved tube made opening in the laryngeal mask segment, which allows the duct, the tube axis is located almost on the contour ellipsoidea education laryngeal mask segment.

In the patents of this Brain curved tube made opening into the lumen of the mask through the opening, which provides a flexible crossbars to prevent obstruction of the opening of the epiglottis while ensuring the passage of another tube having a smaller size, such as an endotracheal or endobronchial tube, suction catheter, or tube of the endoscopic device, such as fiber optic bronchoscope or laryngoscope.

Brief description of the invention

The present invention is vostokovedenie device, the purpose of which is to overcome certain shortcomings that were identified in the practical application of vostokovednyh devices known from the prior art. Other objectives of the invention are creating vozduhovodnogo device, which is also cheap, easy to install without damaging the tissue of the patient and without requiring the use of a laryngoscope or other endoscopic instrument, as well as providing effect of the main pulmonary ventilation without blocking or obstruction of the duct in use.

Application vozduhovodnogo device according to the invention does not require large expenditures, the device is easily installed and therefore it can be used in emergency medical services. This provides advantages over devices of this type known from the prior art. In vostokovednyh devices on patents of the Brain during the installation process, the formation of folds on the unfilled bezel, the result may be incomplete seal rim after its filling. Incomplete adherence leads to leakage of the filling medium, resulting in a lack of effectiveness vozduhovodnogo device. In addition, we fill our headbands are often adjacent to the duct wall improperly, which also leads to leakage of the filling environment. In addition, when applying vostokovednyh devices on patents of the Brain, the operator is often difficult to determine whether all filled filled bezel. To solve these problems associated with the leakage of the filling medium and the content of the bezel, the operator often fills bezel with excess pressure in the inflatable rim is too high, which may cause damage to the soft tissues in the place of installation of the filled bezel, which serves as a seal.

Another disadvantage vostokovednyh devices to Pat the days before the Brain is when installing the operator is often difficult to determine, in good place mask is set duct above the larynx. This uncertainty in the correct placement of the mask makes the task of ensuring full compaction more difficult, and complicates the task of introducing vozduhovodnogo devices in the respiratory tract of the patient. For this reason vostokovedenie device patent of the Brain are not widely used in the emergency medical services. In addition, fill headbands such vostokovednyh devices to ensure a proper seal must be completely filled with the filling medium, therefore, require a large number of rims of different sizes to match the different sizes of the respiratory tract of patients, which are used vostokovedenie device of this type. As for endotracheal tubes and oropharyngeal or nasopharyngeal vostokovednyh devices, they also had generally unsuitable for use by personnel of the emergency medical services.

When installing vostokovednyh devices known from the prior art, is not secured to prevent accidental introduction of the duct or part of the duct into the esophagus.

And ingress of air flow into the esophagus can cause damage to its delicate tissue that it is undesirable, that is as it may cause the patient serious problems. In addition, vostokovedenie devices known from the prior art often do not have adequate mechanisms to secure in place, and this is very important, especially when applied in the emergency medical services.

The present invention offers vostokovedenie device intended to facilitate lung ventilation in patients who are unconscious, while the proposed device provides overcoming the shortcomings inherent in vozduhovodnom the devices known from the prior art. The device according to the present invention includes a curved but flexible vozduhovodnogo tube and mask segment, which includes the opening section and the support element. Mask segment attached to vozduhovodnogo tube at its front end. The shape of the opening section, intended for the supply of air, such that provided a close fit to the tissues above the laryngeal orifice of the larynx of the patient without penetration into the larynx and without the necessity of sealing the opening of the site, focusing on the larynx or laryngeal opening (entrance to the larynx). The support element has a number of thin and flexible ribs located with stretch from a relatively more rigid core, which is made with stretch in direction is toward the longitudinal axis of the opening section and in the preferred embodiments of the proposed invention is made integral with him. In one of the embodiments of the present invention on one side of the support element at least some of the ribs may have a wavy shape in cross section across their width in order to compensate for the bending or stretching of the support element during installation. Ribs are focusing on the cricoid cartilage of the larynx from the side of the throat, just above the esophagus. This ensures the proper placement of mask segment over the laryngeal opening and securing with a focus on a relatively hard surface without the risk of damage to delicate tissues of the esophagus, larynx or laryngeal opening. When placing the support element based on the cricoid cartilage of the larynx from the pharynx to the operator, establishes vostokovedenie device, provides information about the fact that the opening area of mask segment is installed in the proper place and adequately fixed or installed with the seal. The interaction between the support element and the pharyngeal side of the cricoid cartilage of the larynx helps to ensure that the operator, establishes vostokovedenie device that accurately places the opening area of mask segment, and therefore also ensures proper adherence to vozduhovodnogo tube over the laryngeal opening Hort is no patient. Pharyngeal side of the cricoid cartilage of the larynx is relatively rigid docking area for the mask segment, which provides a stay of the opening area of mask segment in the position of close proximity and circular fit to the laryngeal opening of the larynx of the patient. The opening section of mask segment has a shape corresponding to the space around the laryngeal opening, providing for the admission of air to the laryngeal opening without the necessity of creating a seal at the periphery of the laryngeal opening and no penetration into the larynx or esophagus.

The shape of the opening area of mask segment is very close to the shape of the laryngeal opening. Because when applying vozduhovodnogo device according to the invention does not require sealing with emphasis on the laryngeal opening, and since the supporting element vozduhovodnogo device according to the invention, made with the possibility of fixing on a relatively hard tissues of the pharyngeal side of the cricoid cartilage of the larynx or seals based on these fabrics to fit to a wide range of sizes of the respiratory tract of patients will need a few different sizes vostokovednyh devices offer the mu to the invention, it has significantly reduced the number of sizes vozduhovodnogo device. Due to this advantage of the present invention decreases the cost of the device, it becomes more suited for use in emergency medical services, as the ambulance will have smaller different sizes, resulting in the free space in the car. In addition, the seal support element based on the pharyngeal side of the cricoid cartilage of the larynx provides a good tactile indication of proper placement of the opening area of mask segment in the respiratory tract of the patient, providing ease and precision injection vozduhovodnogo device according to the invention, in the respiratory tract of the patient.

Vostokovedenie device according to the invention is easily and conveniently introduced into the respiratory tract of most patients. This vostokovedenie device is also cheap to manufacture and can be produced in large quantities, whereby it may be manufactured as a disposable. This creates prerequisites for use vozduhovodnogo device according to the invention, in emergency medical services or for other applications outside of the medical Stazione is a, as well as in surgery. When the reference element mask segment reaches the pharyngeal side of the cricoid cartilage of the larynx above the esophagus, the operator sets vostokovedenie device, you may feel a certain point it stops, what is the evidence that the mask segment is installed correctly. Mask segment does not penetrate into the larynx or trachea, and the reference element does not penetrate into the esophagus, making it possible to avoid the risk of damage to these delicate structures.

In the same way when applying vozduhovodnogo device according to the invention, it is possible to avoid the risk of penetration of the mask segment in the esophagus or one of the main bronchi. Being established in its place, vostokovedenie device according to the invention allows to perform pulmonary ventilation by creating excessive pressure. Or after the introduction of vozduhovodnogo device the patient can be given the ability to breathe spontaneously.
