Description

Electrolaryngoscope

Technical field

This utility model relates to medical instruments field, particularly a kind of electrolaryngoscope.

Background technology

Electrolaryngoscope is typically made up of photographic head, hollow stereoplasm tube (or claiming " connecting rod "), handle and control display module；The front end of hollow stereoplasm tube is provided with photographic head, and its rear end is fixing with handle to be connected, can be with admittance line inside it；The rear portion of handle connects control display module.In the diagnosis and treatment process using electrolaryngoscope, the general supporting tracheal cartilages of electrolaryngoscope (or claim " tracheal intubation ", or " endotracheal tube ", or " inserting pipe ") use, will insert in tracheal cartilages the hollow stereoplasm tube of electrolaryngoscope, tracheal cartilages circumference is coated with the hollow stereoplasm tube with photographic head and gos deep in patient's cavum laryngis.

In use, owing to human internal environment is dark, the insertion depth at electrolaryngoscope is often not easily controlled, it is therefore desirable to utilize extra light source as guiding, but the process guided will necessarily produce certain vision blind spot, is susceptible to insert not in place or inserted deep situation.

Additionally, in diagnosis and treatment process, the sputum in patient's cavum laryngis can cover all the photographic head of electrolaryngoscope, affect the Checking on effect of doctor, it is therefore desirable to removed in time by sputum.But, use electrolaryngoscope and simultaneously to patient, particularly suction sputum or cavum laryngis nursing to comatose patient is always the difficult point in medical and nursing work, because the inhaling-conveying mode of the conventional assistive device of application tends not to reach thoroughly to remove sputum and the purpose of oral cavity dirt, simultaneously, owing to assistive device used is numerous and diverse, operation is also inconvenient.

Chinese utility model patent CN203388832 (a kind of hose laryngoscope) discloses the suction sputum scheme of a kind of improvement, in order to by sputum sucking-off, this utility model buries Catheter for sputum aspirating in the tube wall of tracheal cartilages underground, axially extending along tracheal cartilages of Catheter for sputum aspirating, its rear end is provided with sputum aspirator interface, its front end has on the inwall of the fore-end that an osculum (i.e. " suction sputum mouth ") is arranged at tracheal cartilages, sputum i.e. by Catheter for sputum aspirating from suction sputum mouth sucking-off.

Chinese utility model patent CN201168310 (a kind of Multifunctional luminous endotracheal tube) also discloses that a kind of suction sputum scheme, improvement with utility model CN203388832 is identical, also in burying Catheter for sputum aspirating in the tube wall of tracheal cartilages underground, suction sputum mouth is an osculum equally, on the inwall of the fore-end being located at tracheal cartilages.

Catheter for sputum aspirating is all located in the tube wall of tracheal cartilages by above-mentioned two utility model, their defect is that the position of suction sputum mouth distance photographic head cannot determine, under normal circumstances, suction sputum mouth can be positioned at distance photographic head remote position, this is because the specification of tracheal cartilages is more, size is the most different.According to " the People's Republic of China's pharmaceuticals industry standard YY0337.1-2002 " regulation to tracheal cartilages, the length that tracheal cartilages matches because of its internal diameter and internal diameter is different, have 19 kinds of specifications, so the position of the photographic head on the more difficult coupling of suction sputum mouth being located on tracheal cartilages wall or corresponding hollow stereoplasm tube, thus cannot effectively absorb or clear up sputum or the dirt of photographic head periphery.

Therefore, with regard to current electrolaryngoscope be correlated with suction sputum scheme prior art for, the insertion process to electrolaryngoscope cannot be realized and directly carry out the scheme of light guiding, simultaneously because suction sputum mouth is all away from maybe can not stably be located at photographic head periphery, and the power of sputum aspirator is typically small, and (the relatively conference of suction sputum power causes patient uncomfortable, or cause the damage of its wall of laryngeal cavity), thus sputum or the dirt being covered in photographic head periphery can not be absorbed the most completely；Even if suction sputum mouth is just at the periphery of photographic head, owing to simply certain point in photographic head periphery side carries out suction sputum, still can not effectively remove the sputum of photographic head periphery.

Utility model content

The purpose of this utility model is to provide a kind of electrolaryngoscope with sputum aspirator, it can more effectively solve the technical problem that the photographic head that above-mentioned prior art run into is blocked by sputum or dirt, and overcome the defect of above-mentioned prior art, the insertion process of electrolaryngoscope can be carried out guiding in real time illumination, and can quickly and completely remove the object being covered in photographic head periphery.
