Problems solved by technology

The disadvantage is that it is not easy to insert the endotracheal tube into the patient's trachea due to the reasons of the endotracheal tube itself (such as large diameter, non-circular shape of the insertion end, etc.) during operation; It is difficult for personnel to observe the state of the trachea, and sometimes it takes repeated times to insert the intubation tube into the trachea, which can easily cause throat edema or mucosal injury and bleeding in patients, leading to serious consequences

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and examples, but the examples should not be construed as limiting the present invention.

[0016] figure 1 The disclosed structure is that of an embodiment of the present invention.

[0017] refer to figure 1 , the guide light rod 1 of the present invention is a hollow smooth rod, and the guide light rod 1 is at an angle of 150°-165° at 25 mm from the front end, which avoids frontal collision between the front end of the guide rod and the glottis during insertion into the trachea. An optical fiber bundle 2 is arranged inside the hollow rod. A battery 5 and a light bulb 4 are arranged inside the casing 3 of the lighting device, and a switch 6 is arranged on the casing 3 . When the present invention is used, a light-emitting device is inserted at the end of the guide light rod 1, and the light source emitted by the light bulb 4 is transmitted to the front end of the gui...

Abstract

The invention discloses a guiding optical wand for constructing an artificial airway. The guiding optical wand is a smooth hollow rod with the front end shaped in a sealed arc, a fiber-optic bundle (2) is arranged in the hollow rod, a detachable light emitting device is arranged at the tail end of the guiding optical wand which is composed of a shell (3), a bulb (4), a battery (5) and a switch (6). Light sources emitted by the light emitting device are guided to the front end of the guiding optical wand (1) via the fiber-optic bundle (2), so that arrangement of a light emitting body and a guide wire in the guiding optical wand is avoided, and the guiding optical wand is lighter and more prone to shaping, and blind exploring direction is easy to change. The guiding optical wand is simple in structure, before insertion of the guiding optical wand, sleeving of a trachea cannula is not needed, only the guiding optical wand needs to be inserted singly, and the guiding optical wand is low in resistance and can pre-lead the trachea cannula to be inserted into a trachea accurately, trachea cannula inserting time can be shortened, success rate and safety of trachea cannula insertion are improved, and the artificial airway can be constructed quickly and safely.

Description

technical field [0001] The invention relates to a medical device, in particular to a guiding light rod used for establishing an artificial airway with a simple structure and convenient operation. Background technique [0002] At present, the way that hospitals establish artificial airways for patients is to directly insert endotracheal tubes into the trachea. The disadvantage is that it is not easy to insert the endotracheal tube into the patient's trachea due to the reasons of the endotracheal intubation itself (such as large diameter, non-circular shape of the insertion end, etc.); It is difficult for personnel to observe the state of the trachea, and sometimes the intubation can be inserted into the trachea several times, which can easily cause throat edema or mucosal injury and bleeding in patients, leading to serious consequences. Contents of the invention [0003] The purpose of the present invention is to provide medical personnel with a simple-structured and easy-...
