Description
Technical field
This utility model relates to a kind of electrolaryngoscope, particularly a kind of electrolaryngoscope with sputum aspirator.
Background technology
Electrolaryngoscope is generally 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 fixedly connected with handle, and its inside can admittance line; The rear portion of handle is connected with 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 " insertion tube ") use, hollow stereoplasm tube by electrolaryngoscope inserts in tracheal cartilages, and the tracheal cartilages circumference hollow stereoplasm tube be coated with photographic head gos deep in patient's cavum laryngis.
In diagnosis and treatment process, the sputum in patient's cavum laryngis can cover the photographic head of electrolaryngoscope completely, affects the Checking on effect of doctor, therefore needs sputum to remove in time.But, use electrolaryngoscope also simultaneously to patient, particularly the difficult point in medical and nursing work to the suction sputum of comatose patient or cavum laryngis nursing always, because the inhaling-conveying mode applying conventional assistive device often can not reach the object thoroughly removing sputum and oral cavity dirt, simultaneously, because assistive device used is numerous and diverse, operation is also inconvenient.
Chinese utility model patent CN203388832 (a kind of hose laryngoscope) discloses a kind of suction sputum scheme of improvement, in order to by sputum sucking-off, this utility model buries Catheter for sputum aspirating underground in the tube wall of tracheal cartilages, Catheter for sputum aspirating extends along the axis of tracheal cartilages, its rear end is provided with sputum aspirator interface, its front end has an osculum (i.e. " suction sputum mouth ") to be arranged on the inwall of the fore-end of tracheal cartilages, sputum namely by Catheter for sputum aspirating from the sucking-off of suction sputum mouth.
Chinese utility model patent CN201168310 (a kind of Multifunctional luminous endotracheal tube) also discloses a kind of suction sputum scheme, identical with the improvement of utility model CN203388832, bury Catheter for sputum aspirating underground in the tube wall of tracheal cartilages equally, suction sputum mouth is an osculum equally, is located on the inwall of the fore-end of tracheal cartilages.
Catheter for sputum aspirating is all located in the tube wall of tracheal cartilages by above-mentioned two utility models, their defect is that the position of suction sputum mouth distance photographic head cannot be determined, under normal circumstances, suction sputum mouth can be positioned at distance photographic head position far away, this is because the specification of tracheal cartilages is more, size is also all different.According to " the People's Republic of China (PRC) 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 be located at the position of the more difficult coupling of suction sputum mouth on tracheal cartilages wall or the photographic head on 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 with regard to, because suction sputum mouth is all located at photographic head periphery away from maybe not stablizing, simultaneously general less (suction sputum power comparatively conference causes patient uncomfortable to the power of sputum aspirator, or cause the damage of its wall of laryngeal cavity), thus effectively can not absorb the sputum or dirt that are covered in photographic head periphery completely; Even if suction sputum mouth is in the periphery of photographic head just, owing to just a bit carrying out suction sputum in certain of photographic head periphery side, the sputum of photographic head periphery still effectively can not be removed.
Utility model content
The purpose of this utility model is to provide a kind of electrolaryngoscope with sputum aspirator, it more effectively can solve the technical problem that photographic head that above-mentioned prior art runs into is blocked by sputum or dirt, and overcome the defect of above-mentioned prior art, thus can fast and completely remove the object being covered in photographic head periphery.
Inventor of the present utility model finds through a large amount of experiments and research, suction sputum mouth and sputum passage thereof is formed in the peripheral extent of photographic head, certain being better than away from photographic head of its suction sputum effect and efficiency a bit carries out suction sputum, and the mode of operation of integration is more convenient, be more conducive to medical personnel's use.Based on above-mentioned discovery, this utility model is accomplished.
