Description

The sleeve type laryngoscope

Technical field:

This utility model relates to a kind of medical apparatus and instruments, especially a kind of laryngoscope of conveniently assemble and disassemble.

Background technology:

Previously rescue respiratory failure, breathe poly-patient such as stop, as when carrying out endotracheal intubation, need operate by anesthetic laryngopharyngoscope.The laryngoscope that hospital uses now constitutes by material can be divided into rustless steel laryngoscope and plastics laryngoscope, can be divided into the disposable laryngoscope that uses and reuse by access times.No matter be import, still home-made, price is all very expensive, and hospital often adopts the sterilization back to reuse, if but in clinical sterilization not thorough, the virus between the patient is cross infection easily then, makes dopey patient might suffer from new disease.But, be difficult to promote the use of owing to the cost height at present for disposable laryngoscope.

In existing laryngoscope, no matter be plastics or stainless, no matter be import, still home-made, its structure is similar: mainly be made of handle and eyeglass two parts.In use, only eyeglass is partly carried out disinfection, handle generally need not sterilized.Equipped with battery in the handle cavity, install luminescent device below the front end of eyeglass, luminescent device links to each other with battery in the handle by electric wire, and handle and eyeglass are two independently parts, the connection of mechanical part relies on buckling device, and electric connection is then by contact contact (as shown in Figure 1).In clinical use, the fault rate of the connection of mechanical part is lower, generally can not take place; The connection of electric part but often goes wrong, and is promptly not luminous because of electrical contact loose contact luminescent device, and what influence was performed the operation normally carries out, and disposable laryngoscope of this phenomenon and reusable laryngoscope all occurred.

Summary of the invention:

The purpose of this utility model is to overcome the weak point of existing anesthetic laryngopharyngoscope configuration aspects, and a kind of sleeve type laryngoscope is provided.

This utility model, comprise handle and eyeglass, it is characterized by: in the lower end of handle, the mirror core is set, and mirror core and handle constitute " L " shape, and mirror core and handle design for consubstantiality or the allosome fixed connection structure, its inside is provided with cavity and lead channels, its intracavity equipped with battery and electronic component, the front end installing luminous organ of mirror core, luminous organ directly is connected with electronic component and battery by lead; Below eyeglass, be provided with and the mirror core tube chamber of fit mutually, the antetheca of tube chamber is closed and is transparent configuration that the rear end is for fastening locking device.

This utility model, if eyeglass adopts transparent material to make, then the antetheca of tube chamber and eyeglass are same body structure, if eyeglass adopts non-transparent material to make, then the antetheca of tube chamber and eyeglass body are combinative structure.

This utility model, can be at the front end installing video perception device of described mirror core, be equipped with the signal processing apparatus that is connected with the video perception device at handle or mirror core intracavity,, then constitute laryngoscope with video capability if signal processing apparatus is connected with the display that is arranged at the handle top; If signal processing apparatus is connected with the video transmission device, the outer supporting wireless video receptor of video transmission device and the TV or the display that are attached thereto then constitute the laryngoscope that has the wireless visible device.

This utility model also can be provided with the conduit approaching channel in the lower limb extension of the laryngoscope eyeglass with video capability, makes its directly guide cannula.

This utility model, because handle and mirror core constitute the main part of laryngoscope, be reusable medical apparatus and instruments, the required battery of laryngoscope, luminous organ or and video perception device and other components and parts all be installed on handle or the mirror core, adopt lead directly to connect between electrical part, fundamentally stop the fault that causes because of poor contact of contacts, thereby improve the reliability of laryngoscope greatly; In addition, laryngoscope in use, laryngoscope body---handle does not directly contact with patient with the mirror core, also needn't be to handle and the disinfection of mirror core, thereby improve the ruggedness of laryngoscope.

This utility model and since eyeglass and mirror core combine that to adopt sleeve type syndeton, eyeglass be directly and the part of contact patients, and eyeglass do not contain electrical appliance part, thereby carries out disinfection after can dismantling easily, or disposable use after sterilizing.The laryngoscope of the same type with tradition compares, and can reduce sterilization expense or production cost greatly, especially can reduce the production cost of disposable laryngoscope.Be significant to promoting the use of disposable laryngoscope (eyeglass).

This utility model, because eyeglass adopts the sleeve type syndeton with combining of laryngoscope body, therefore, the eyeglass that adopts the different structure form and the mirror core one-tenth capable of being combined of different configurations have difference in functionality (as throw light on, can stick up, video, oxygen supply, display screen etc.) laryngoscope.

This utility model has characteristics such as simple in structure, science, practicality.Have and promote preferably and use value.
