Emergency dual-chamber dual-cuff throat vent pipe

Abstract

The invention discloses an emergency dual-chamber dual-cuff throat vent pipe. The emergency dual-chamber dual-cuff throat vent pipe comprises a main vent pipe, an auxiliary pipe, a multiple-ventilation opening and a cuff charging assembly, wherein the main vent pipe adopts straight line design, the cross section of the main vent pipe is in the shape of a circle, and an integration dental pad and depth scales are arranged / formed at / in the near end of the main vent pipe; the auxiliary pipe slantways penetrates in the near-section pipe wall of the main vent pipe, travels in the pipe chamber of the main vent pipe, and threads out at the position of the multiple-ventilation opening at the far end of the main vent pipe; a far-end opening adopts inclined design; the main vent pipe and the auxiliary pipe are prepared from medical silica gel materials; the multiple-ventilation opening is totally provided with 4-6 outlets in annular average distribution, is inclined when being viewed from the side surface, and is located between the far end of the main vent pipe and the auxiliary pipe; and the cuff charging assembly contains a large cuff, a small chuff, a pressure measuring air-charged bag and a charging connecting pipe, and the pressure measuring charging bag can be used for charging the large cuff and the small cuff and at the same time and can measure the pressure in the bag. The emergency dual-chamber dual-cuff throat vent pipe disclosed by the invention has different model sizes, is simple and convenient to operate, can be freely inserted for use, and is high in safety and validity.

Description

technical field [0001] The invention relates to a ventilation device, in particular to an emergency double-cavity double-cuff throat ventilation tube. Background technique [0002] In many cases in clinical medical work, patients may experience airway obstruction or risk of obstructed aspiration, or respiratory and ventilatory insufficiency, or during general anesthesia operations, it is necessary to use certain ventilation equipment at this time to ensure that the patient’s airway is unobstructed and assist or Control ventilation. [0003] The current non-invasive airway ventilation equipment includes three types: face masks, endotracheal tubes, and supraglottic ventilation equipment, each of which is suitable for different situations and has its own advantages and disadvantages. The effect of mask ventilation is limited, and it is often used in transition when the conditions are not available or short-term ventilation; endotracheal intubation requires intubation equipment...

AI Technical Summary

Problems solved by technology

The effect of mask ventilation is limited, and it is often used in transition when the conditions are not available or short-term ventilation; endotracheal intubation requires intubation equipment, professional skills, and the possibility of failure of difficult airway intubation; there are many types of supraglottic ventilation equipment, each with Advantages, but there are also defects such as the need for certain operational skills, certain placement and ventilation failure rates, and certain complications.

[0004] Especially in the absence of professional airway management personnel and the need for emergency ventilation (such as pre-hospital first aid or first aid outside the hospital operating room), the difficulty of safe and effective application of the above airway management equipment will increase
