Problems solved by technology

[0004] (1) Pressurized ventilation with nasopharyngeal airway placement: However, some patients still cannot improve ventilation due to obesity, soft palate or tongue hypertrophy, excessively long nasal passages, obstructed posterior nasal pore and poor position of nasopharyngeal airway;
[0005] (2) Place supraglottic ventilation tools such as oropharyngeal airway, laryngeal mask, esophagus-trachea tube, laryngeal tube, etc. to pressurize oxygen: However, the placement of the above devices requires a mouth opening of about 2-3 cm, and for mouth opening less than 2 cm , 1cm, and 0.1cm patients cannot be inserted; and some patients with unlimited mouth opening may experience problems due to obesity, soft palate or tongue hypertrophy, too long or too short neck, implanted position Clinical conditions that still cannot improve ventilation, such as suboptimal;
[0006] (3) Try tracheal intubation again: Although this method has a slight success rate, it still has the defect that the laryngoscope cannot be placed in patients with limited mouth opening, and it is easy to force intubation for patients who do not meet the intubation conditions. Induce laryngospasm, bronchospasm and other life-threatening clinical situations
[0007] (4) Emergent cricothyropuncture tube insertion or tracheotomy: it is an invasive method, which is easy to damage the airway and cause serious sequelae, and still has the defects of puncture or incision failure and time-consuming
[0008] (5) The visual ventilation laryngoscope (patent number: 201220117131.4) granted by the State Intellectual Property Office of the People's Republic of China and the visual ventilation intubation laryngoscope (patent number: 201210417431.9) granted an invention patent have the following defects: First, The ventilation of both is realized through the ventilation handle, and the ventilation handle contains the ventilation lumen and the visible structure, which requires the handle to have a certain thickness. Or the difficult ventilation situation of patients with slightly limited mouth opening, and for patients with difficult ventilation with limited mouth opening (such as mouth opening less than 2cm, 1cm, 0.1cm) and tumors or foreign objects occupying space in the mouth, it cannot be placed because it cannot be placed. play a role; and both can only be ventilated through the mouth, not through the nasal cavity
Therefore, difficult fiberoptic bronchoscopic tracheal intubation lacks a device that can increase the exposure space of the pharyngeal cavity in patients with limited mouth opening

Embodiment 1

[0053] A lifting throat organizer, the lifting throat organizer 1 includes a detachable lifting handle 11, a lifting bent piece component 12 and a visualization component 13;

[0054] In one possible implementation, such as Picture 1-1 and Figure 1-4 As shown, the lifting handle 11 is provided with an insertion channel 121 for lifting the bending piece assembly and an insertion channel 131 for the visualization component. 13 can move freely up and down in the corresponding component embedding channel and can be fixed by the corresponding component fixer, and the corresponding component embedding channel can be compatible with lift-up bent piece components 12 or visualization components 13 of different shapes, models and sizes.

[0055] Further preferably, as Figure 1-2 and Figure 1-5 As shown, the lifting bent piece assembly 12 is provided with a bent piece handle 122 and a bent piece 123; the upper end of the bent piece handle 122 can extend into the insertion channel 1...

Embodiment 2

[0062] A device for a difficult airway, which has the elevating throat organizer 1 described in Embodiment 1, and also includes a mask 2 . The mask 2 has a mask breathing circuit interface 25, which can be a conventional mask 2 or an optimized mask 2 provided by the present invention.

[0063] Among them, in a feasible implementation, such as diagram 2-1 , Figure 2-2 and Figure 2-3 As shown, the mask 2 includes a mask body. The front of the mask body is designed with a lip wall 21 similar to the appearance of the lips and a nasal front wall 22 similar to the appearance of the front of the nose. When in use, when the mask body is placed on the patient's mouth and nose When in the upper part of the mouth, the lip wall 21 is located above the patient's mouth, and the front nose wall 22 is located in front of the patient's nose, facing the nostrils; the lip wall 21 is provided with an insertion port for lifting the throat tissue, and the insertion port for the lifting throat ...

Embodiment 3

[0069] A device for difficult airways, comprising a lifting throat organizer 1, a face mask 2, and a disposable protective cover 3. First, the lifting throat organizer 1 is composed of a detachable lifting handle 11, a lifting curved piece assembly 12, and a visualization component 13; the lifting handle 11 is provided with a lifting curved piece component insertion channel 121, a visualization component insertion channel 131 and component fixer 111; Lifting bent piece assembly 12 is provided with bent piece handle 122, bent piece 123, disposable protective cover bent piece fixing protrusion 124; Visualization component 13 is provided with visible carrier handle 132, endoscope 133 , wireless digital imaging transmitter module 134, wireless digital imaging receiver 135, power supply 136, disposable protective cover visualization fixed protrusion 137, there are micro-camera 1331, light source 1332 to pass through in the tube body of endoscope 133, wireless digital imaging receive...

Abstract

The invention provides an instrument for lifting throat tissue, and belongs to the technical field of medical apparatus and instruments. The instrument comprises a lifting handle and a lifting bent piece assembly which are detachably connected, the lifting bent piece assembly is provided with a bent piece, the thickness of the bent piece is 0.5-1 mm, and the width of the bent piece is 1-2 cm; theend of the bent piece is fixedly connected with the lifting handle, and the front end of the bent piece can enter from the oral cavity and reach the throat of a patient. The instrument for lifting thethroat tissue can expand the oropharyngeal space of the patient who is extremely restricted to opening the mouth, so that a broad and unobstructed ventilation or intubation path is formed in the oropharynx of the patient, and convenience is provided for a doctor to perform endotracheal intubation of a fiberoptic bronchoscope or other intubation auxiliary devices. The invention also provides a device used for complicated airways.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a device for lifting throat tissue and a difficult airway. Background technique [0002] A difficult airway is a clinical condition in which an anesthesiologist with more than five years of anesthesia experience has difficulty performing mask ventilation or intubation. [0003] "Patients will only die from failure of ventilation, not failure of intubation." In clinical practice, once difficulty in ventilation is encountered, the patient will easily enter a state of hypoxia and cause asphyxiation and death. The existing technical solutions and existing defects for difficult ventilation mainly contain the following: [0004] (1) Pressurized ventilation with nasopharyngeal airway placement: However, some patients still cannot improve ventilation due to obesity, soft palate or tongue hypertrophy, excessively long nasal passages, obstructed posterior nasal pore an...
