Positioning sputum suction laryngeal mask

Abstract

The invention relates to a positioning sputum suction laryngeal mask. The positioning sputum suction laryngeal mask comprises a cover body and a cover body tube; the cover body comprises a cover bodybottom plate and a cover main body arranged on the cover body bottom plate, a central region in the cover main body is provided with a cover body cavity which can be communicated with the cover body tube, an appetite tube corresponding to the appetite is arranged on the back side of the cover body bottom plate, the appetite tube is isolated from the cover body cavity through the cover body bottomplate; the positioning sputum suction laryngeal mask also comprises a connection suction mechanism which can realize the negative pressure suction in the gas supply process, wherein the connection suction mechanism comprises a suction connection pipe which is arranged in the cover body bottom plate, and the end part, in the cover body bottom plate, of the suction connection pipe is communicated with the appetite pipe. The positioning sputum suction laryngeal mask can effectively meet the positioning of the laryngeal mask, reduce the complexity of the laryngeal mask and the using cost, and canensure the ventilation and sealing effect of the laryngeal mask when the laryngeal mask is in use, can realize the suction of the secretion in the ventilation process, avoid the epiglottis and the dead air passage, and improve the stability and the reliability of the laryngeal mask.

Description

technical field [0001] The invention relates to a laryngeal mask, in particular to a positioning phlegm-suction laryngeal mask, which belongs to the technical field of medical instruments. Background technique [0002] Laryngeal mask, as a medical device used to maintain patients' breathing and ventilation, is widely used in clinical anesthesia, first aid or resuscitation because of its non-invasive airway characteristics. Along with the progress of material and technology, existing multiple improved laryngeal mask is used clinically at present, but the laryngeal mask of prior art still has many problems to exist. [0003] The current laryngeal masks use airbags or soft rubber rings to cover the glottis to achieve a sealing effect. The essence of the seal is that the airbags or soft rubber rings press the throat mucosa surrounding the glottis. The pressure is perpendicular to the pressure of gas leakage, and the sealing effect is poor. , to achieve the clinical sealing effe...

AI Technical Summary

Problems solved by technology

[0003] The current laryngeal masks use airbags or soft rubber rings to cover the glottis to achieve a sealing effect. The essence of the seal is that the airbags or soft rubber rings press the throat mucosa surrounding the glottis. The pressure is perpendicular to the pressure of gas leakage, and the sealing effect is poor. , to achieve the clinical sealing effect requires a large pressure, which often leads to postoperative throat pain in patients; and when the pressure is low, gas leakage often occurs, resulting in ventilation failure or aspiration of saliva into the airway

[0004] Current laryngeal masks cannot effectively suction sputum during respiratory support, and forced suction often leads to air leakage and throat friction damage

The laryngeal masks that are widely used clinically are all air bag type, which require high pressure on the air bag when in use, and need to be inflated and deflated, which is cumbersome to use

[0005] During anesthesia with laryngeal mask respiratory support, when the patient's head and neck move slightly, the positioning relationship between the laryngeal mask and the glottis will be destroyed, which will lead to a decrease in the airtightness of the laryngeal mask and even failure to achieve respiratory support

In order to re-realize the respiratory support of the laryngeal mask, it is generally necessary to adjust the position of the laryngeal mask and the glottis again. If the adjustment fails, tracheal intubation is required; at this time, the difficulty of tracheal intubation will increase greatly, which will bring troubles to doctors and patients. bring risk
