CN203017527U - Sputum suction type laryngeal mask - Google Patents

Abstract

The utility model relates to a sputum suction type laryngeal mask, which comprises a laryngeal mask body, an air bag, an air bag air-filling pipeline and a ventilation catheter, wherein the laryngeal mask body and the ventilation catheter are fixedly connected; the air bag is around the laryngeal mask body; one end of the air bag air-filling pipeline is connected with the air bag; and a one-way valve is arranged at the other end of the air bag air-filling pipeline. The sputum suction type laryngeal mask is characterized in that a special sputum suction pipeline is also arranged on the sputum suction type laryngeal mask. The sputum suction type laryngeal mask disclosed by the utility model is simple in structure; ventilation and auxiliary sputum suction can be carried out simultaneously, and therefore, sputum suction can be carried out at any time; gathering of sputum and secreta is reduced; the mis-suction occurrence rate is greatly reduced; the sputum suction type laryngeal mask is applied to long-time mechanical ventilation and long-time general anesthetic control or auxiliary ventilation; and in addition, once patients have anesthetic accidents, quick input breathing support is not influenced.

Description

A suctionable laryngeal mask

technical field

The utility model relates to a laryngeal mask, in particular to a phlegm-absorbing laryngeal mask.

Background technique

The application of the laryngeal mask brings great convenience to clinical anesthesia, and at the same time reduces the suffering of patients with tracheal intubation, thereby reducing respiratory complications. This traditional laryngeal mask, its outer mouth structure includes a breathing joint for gas exchange and an air injection port for inflating the air bag in the laryngeal mask. No matter in terms of structure or clinical application, this laryngeal mask lacks a device for suctioning sputum, especially During general anesthesia, as the operation time increases, the secretions in the oral cavity will increase and accumulate, which will increase the possibility of aspiration. Sputum suction and respiratory lavage will bring great potential safety hazards to patients. In the event of an anesthesia accident, effective ventilation cannot be put into place in time, and the laryngeal mask must be pulled out and the trachea intubated, which is time-consuming, especially for patients with poor cardiopulmonary function, and has a potentially huge risk.

Utility model content

The utility model aims at the deficiencies in the prior art, and provides a phlegm-absorbing laryngeal mask capable of performing ventilation and assisted phlegm suction simultaneously.

The technical solution of the utility model to solve the above-mentioned technical problems is as follows: a phlegm-absorbing laryngeal mask, comprising a laryngeal mask body, an air bag, an air bag inflation pipe and a ventilation catheter, the laryngeal mask body is fixedly connected with the ventilation catheter, the The airbag surrounds the body of the laryngeal mask, one end of the airbag inflation pipeline is connected to the airbag, and the other end is provided with a one-way valve. Special pipe for suctioning sputum.

Further, the dedicated sputum suction pipeline is attached to the inner wall of the ventilation catheter and is independent of each other, the inlet of the dedicated sputum suction pipeline is set on the back of the laryngeal mask body, and the outlet of the dedicated sputum suction pipeline is set on the back of the ventilation catheter end.

Further, two suction inlets are provided at the joint between the entrance of the special suction pipe and the back of the laryngeal mask body.

The beneficial effects of the utility model are: the utility model has a simple structure, ventilation and auxiliary sputum suction can be carried out simultaneously, so that sputum suction can be performed at any time, the accumulation of sputum and secretions can be reduced, and the incidence of aspiration is greatly reduced; it is suitable for long-term use Timed mechanical ventilation and long-term surgical ventilation, once an anesthesia accident occurs to the patient, will not affect the rapid rescue of breathing.
