An adjustable length anesthesia laryngoscope

Abstract

The invention relates to an anesthesia laryngoscope for tracheal intubation, in particular to an adjustable length anesthesia laryngoscope, which belongs to the field of medical instruments. It is mainly composed of a handle, a support tube, a display, a camera, a nut holder, a control circuit, a lighting element, a battery, a slider, and a strip electrode; it is characterized in that the support tube and the handle can slide relatively, and the Indicates the position status of the support tube. In the present invention, a slidable connection is adopted between the support tube and the handle, and a deformation claw that can be deformed by being squeezed by the nut holder is provided at the lower end of the handle to realize the fixing of the handle to the support tube, and the support tube The position status of the device can be displayed, thereby having the beneficial effects of being adaptable to endotracheal tubes of different lengths, and being easy to operate and simple in structure.

Description

technical field [0001] The invention relates to an anesthesia laryngoscope for tracheal intubation, in particular to an adjustable length anesthesia laryngoscope, which belongs to the field of medical instruments. Background technique [0002] In clinical medicine, before anesthesiologists use anesthesia machines, ventilators and other equipment for patients, they generally need to intubate the patient, that is, insert a tracheal tube into the patient's trachea for connection to breathing equipment. When performing tracheal intubation, the support of intubation equipment is required, and the commonly used equipment is mainly anesthesia laryngoscope. After the doctor uses anesthesia laryngoscope to expose the glottis of the human body, the endotracheal tube is inserted behind the glottis. After years of development, various types of anesthesia laryngoscopes have emerged, such as the Chinese patent with application number 00214798.x and the name "Adjustable Medical Anesthesia...

Problems solved by technology

After years of development, various types of anesthesia laryngoscopes have emerged, such as the Chinese patent with application number 00214798.x and the name "Adjustable Medical Anesthesia Laryngoscope". This is a traditional anesthesia laryngoscope. Use this anesthesia laryngoscope to lift up the patient's epiglottis to expose the glottis, and then insert the tracheal tube into the patient's trachea behind the glottis, which may cause tissue damage to the patient and is inconvenient to operate; another example is application number 200920301231.0, name It is a Chinese patent for "tracheal intubation endoscope with direct display". This is an electronic anesthesia laryngoscope similar to an endoscope. It is directly placed on the electronic anesthesia laryngoscope, and the endotracheal tube is also inserted into the human body when the electronic anesthesia laryngoscope is inserted into the human body, which is more advanced than the traditional anesthesia laryngoscope; the electronic anesthesia laryngoscope similar to the endoscope There are still many patent applications, such as the Chinese patent application whose application number is 201020113473. When the length of the endotracheal tube is used, a positioning seat is set on it and the actual position of the positioning seat is adjusted according to the length of the endotracheal tube to adapt to different lengths of the endotracheal tube, and its length is not adjustable
