Definitions

  • the invention relates to the field of medical equipment, namely to laryngeal masks.
  • the laryngeal mask has established itself as a safe duct that rarely leads to complications.
  • the primary laryngeal mask / JIM / was used in elective surgery in patients without the risk of regurgitation.
  • JTM has become so popular that its scope is constantly expanding.
  • LM is included in standards for difficult intubation in many countries.
  • JIM has also been used in emergency patients with a risk of regurgitation. This fact leads to the need for a safer mask for regurgitation and aspiration.
  • the first is to block the exit of gastric contents at the level of the esophagus or larynx so that it cannot exit and enter the trachea.
  • SUBSTITUTE SHEET (RULE 26) US Pat. No. L25632271 describes an airway device with a laryngeal mask. In addition to the airway tube for ventilating the patient’s lungs, this device also includes a drainage tube for draining or removing the burped stomach contents. The distal end of the drainage tube is placed near the patient's usually closed esophagus. In addition to providing drainage, the drainage tube can be used as a guide for the insertion of a gastric tube.
  • US> GS6439232 describes a commercially available laryngeal mask with an inflated cuff and a small diameter gastro-drainage.
  • the diameters of the drainage channels of the masks according to US Pat. Nos. 6439232B1, WO.Ns.2005 / 011784, WO # 22004016308, are not adequate to ensure the outflow of gastric contents. Their channels are too small in diameter and can be blocked by solid particles of gastric contents. Through such a channel, it is impossible to establish a gastric tube of sufficient diameter to adequately drain the stomach cavity.
  • the mask according to US patent JN25878745 has a channel of a larger diameter, but insufficient to install a gastric tube of significant diameter, which will adequately drain the stomach.
  • a mask having a gastro-drainage channel adequate in diameter is a mask according to WO .Na 01/24860. We chose her as a prototype.
  • SUBSTITUTE SHEET (RULE 26) Description of the prototype: the device consists of 2 air tubes, an inflated cuff and one wide-channel gastro-drainage, which runs along the midline of the laryngeal part of the device and opens into the esophagus.
  • the problem with this mask is that the gastro-drainage canal, passing along the midline, occupies most of the space intended to accommodate the anatomical formations of the larynx (mask nests). Due to the fact that the distance between the posterior pharyngeal wall and the larynx is limited, the gastro-drainage canal will inevitably put pressure on the larynx, which can lead to undesirable reflex responses.
  • the second problem of the prototype mask an adequate gastric tube conducted through the gastro-drainage opening covers the entire lumen of the gastro-drainage, and the gastric contents that rise to the level of the larynx in addition to the probe due to reverse peristalsis or during obstruction of the drainage holes of the gastric tube will not be removed from the larynx. This may result in aspiration of this contents into the trachea. This makes it difficult to use this device in patients with a risk of regurgitation and aspiration.
  • the objective of the invention is the creation of a laryngeal mask, which allows you to adequately drain the stomach, providing unhindered passage of gastric contents simultaneously from the stomach and esophagus to the outside of the mouth.
  • the cuff in the form of a sealing ring is formed by a horseshoe-shaped rim and two wide-channel gastro-drains, the lumens of which are connected, forming a common gastro-drainage hole opening into the esophagus, while the plane of the o-ring is closed on one side by the sheath.
  • the device additionally contains an introducer, allowing you to change the shape of the sealing ring, in order to facilitate its introduction into the respiratory tract of the patient. And also contains a channel of a smaller diameter, the distal end directed to the glottis.
  • the horseshoe-shaped rim can be made as hollow or solid.
  • the shell of the o-ring can be made as single-layer or multi-layer.
  • the claimed laryngeal mask is quickly and easily installed even in the neutral position of the neck, that is, without bending the cervical spine, which is optimal in cases where the patient’s neck is damaged, there is a suspicion of a fracture of the neck or the neck is mobile.
  • a positive result is also the minimization of risks for the patient associated with personnel error, which are inevitable with mass use of the device. This is achieved due to the fact that it should not contain inflated parts, since in case of personnel error, improper inflating can damage the patient. Additionally, if there is a need for endotracheal intubation, the introduction of drugs into the trachea or the vocal cords, the claimed device should simplify this procedure. In addition, it is relatively simple and inexpensive to manufacture and is another constructive option for a disposable or reusable airway device with a laryngeal mask.
  • the inventive device has two gastro-drainages of large internal diameter, up to 15 mm for an adult patient, one of which can be used to hold the probe into the stomach, with the aim of draining and washing the stomach, the second is used to freely drain the stomach contents from the esophagus.

Abstract

L'invention concerne des équipements médicaux et notamment des masques laryngés. Dans un masque laryngé, une manchette se présentant comme une bague d'étanchéité est formée par un anneau en 'U' et deux drainages gastriques à voie large dont les lumières se connectent entre elles de façon à former un orifice de drainage gastrique commun qui s'ouvre dans l'œsophage. Le plan de la bague d'étanchéité est obturé d'un des côtés par une pellicule. En outre, le dispositif comprend un introducteur. Le masque laryngé de l'invention fait partie des dispositifs simples et peu coûteux à la fabrication. Son faible coût de fabrication permet de l'utiliser comme un dispositif jetable. Le masque présente une sécurité élevé vis-à-vis du patient et peut s'utiliser efficacement dans la pratique clinique, même avec des patients aux urgences ou présentant des risques de régurgitation. Le masque peut être installé dans une position neutre du cou.
