technical field

The invention relates to the technical field of medical instruments, in particular to an extension tube for connecting a laryngeal mask.

Background technique

The laryngeal mask is used in general anesthesia surgery. Its main function is to establish an artificial airway and assist the patient to breathe. After using the laryngeal mask, it needs to be connected to a ventilator or anesthesia machine through a breathing circuit. The connecting line between the traditional endotracheal tube and the anesthesia machine or ventilator is mostly a single-way connecting tube. During operation, the anesthesia machine or ventilator must be separated from the endotracheal tube to interrupt the ventilation so as to perform inspection or nursing operations, and the above-mentioned operations have great disadvantages. For example, when the user needs to suck sputum, he must leave the ventilator, which may cause severe hypoxia and endanger his life.

Chinese patent (CN206198420U) discloses an enhanced drainage laryngeal mask, which includes a main duct for air guidance, a secondary duct for drainage, an inflatable tube and a mask body, and the corresponding ends of the main duct and the secondary duct are connected to the mask body Airtight connection, the cover body can be inflated and airtightly connected with the inflatable tube, the main duct is provided with an air intake tube connected to the ventilator, and the main duct is provided with a fiberscope insertion hole for fiberoptic bronchoscope insertion, The fiberscope insertion hole is an elastic hole, and the main conduit is provided with a plugging device corresponding to the fiberscope insertion hole.

Detailed ways

The technical solutions of the present invention will be further described and illustrated through specific examples below.

As shown in Figure 1: an extension tube for connecting a laryngeal mask, including a breathing tube 1 and a connecting tube 2, the diameter of the connecting tube 2 is 10 mm, and the inner diameter of the breathing tube 1 is 8 mm. The lower end of the breathing tube 1 is fixedly connected to the lower side wall of the connecting pipe 2 and communicates with the connecting pipe 2 . The breathing tube 1 can be connected to a ventilator, and the upper end of the connecting tube 2 is a connecting port 9, from which an external pipeline matching the inner diameter of the connecting tube 2 can be introduced, and the diameter of the external pipeline is no more than 6.5mm. The external pipeline can be fiberoptic bronchoscope, tracheal intubation, suction tube, etc. While ventilating, the operator can perform operations such as drainage, sputum suction, and fiberoptic bronchoscopy in a timely and convenient manner. Wherein, the included angle between the breathing tube 1 and the connecting tube 2 is 80°, and the included angle between the breathing tube 1 and the connecting tube 2 is less than or equal to 90°, which facilitates connection and other operations.

The lower end of the connecting pipe 2 is provided with a first connector 7 for connecting to a laryngeal mask, and the first connector 7 is a standard joint, which can be used for different laryngeal masks. The first connecting head 7 can be rotatably connected with the connecting pipe 2 . In actual use, it can be adjusted to the best position for easy use and connection.
