Description

Laryngoscope device

Technical Field

The utility model relates to the technical field of technical medical treatment, in particular to a laryngoscope device.

Background

The common laryngoscope is one of the necessary rescue equipment in the rescue carriage of medical units, and is mainly used for the clinical doctor to insert into the throat for anesthesia operation or rescue asphyxia. The common laryngoscope consists of a peeping sheet and a handle, the peeping sheet needs to enter the oral cavity and the throat when in use, so that a department needs to clean and disinfect the peeping sheet after use or send the peeping sheet to a supply room for disinfection, and the handle part of the department needs to wipe and disinfect the peeping sheet by a disinfection wet tissue.

The lamp beads of a conventional laryngoscope are generally arranged at the head or the tail of a peeping sheet, and the lamp beads can break down and the head of a light guide pipe is worn and yellowed after long-term use and disinfection, so that the light guide performance is reduced; the lamp pearl adopts the mode of thread tightening to install the head at peeping the piece, and the lamp pearl also has the risk that drops the throat in the use. The light source of the conventional common laryngoscope is yellow, and although the conventional common laryngoscope also has white LED light source lamp beads, the conventional common laryngoscope is limited by the internal space of the peeping sheet, so that the light source has darker brightness, narrower spectrum and poorer color rendering property. Two dry batteries and three dry batteries are required to be installed in the handle of the old laryngoscope, and the original stainless steel handle and the peeping sheet are added, so that the use is not flexible due to the heavier weight, and particularly for female doctors.

Because the endoscope is placed in the rescue vehicle for standby for a long time, although the examination is carried out according to the regulation of a nursing department every month, the administrative staff in the department generally can not connect the sterilized laryngoscope peeping sheet to the handle for testing, and can not judge whether the lamp bead of the peeping sheet can work normally without testing, but the test of installing the handle is contradictory to the disinfection. Also, the handle is damaged due to aging and leakage of the battery caused by forgetting to replace the internal battery. Due to long-term use, poor contact can appear in the contact of peeping sheet and handle top power supply circuit, can appear suddenly and suddenly dark during the use. The purchase cost of a set of imported laryngoscopes is about 4500 yuan, which is a small expenditure for departments. The replacement cost of one lamp bead is about 150 Yuan, and the maintenance cost of the later period of the department is higher.
