Description

耳部检查内窥镜及鼻喉检查内窥镜配套用一次性套管 Ear nose and throat examination and endoscopic examination using a disposable endoscopic supporting sleeve

技术领域 FIELD

[0001] 本发明涉及医疗器械,尤其涉及耳鼻喉科医疗器械。 [0001] The present invention relates to medical devices, and more particularly ENT Medical Devices. 背景技术 Background technique

[0002] 目前在耳鼻喉科的临床上,基本还在使用头镜、耳镜以及耳鼻喉内窥镜来做检查。 [0002] Currently in clinical ENT, still using substantially mirror head, an endoscope do otoscope and ENT examination.

[0003] 但是头镜、耳镜有以下不足:1、观察角度受限;2、无法对病变作近距离的观看;3、不能将观察到的东西数字化。 [0003] However mirror head otoscope has the following shortcomings: 1, the viewing angle is limited; 2, the lesion can not be viewed at close range; 3, can not be observed things digitized.

[0004] 耳鼻喉内窥镜也有以下不足: [0004] ENT endoscope also has the following shortcomings:

[0005] 1、传统耳鼻喉镜由于图像显示系统庞大,只能用于医院的腔镜检查室和手术室, 在门诊无使用条件,也不方便移动,因此门诊大夫只能要求患者在腔镜室进行检查。 [0005] 1, the conventional image display ENT mirror because large systems can only be used in hospital operating rooms and endoscopy chamber, in the clinic without the use conditions, not easy to move, and therefore only require the patient to the doctor-patient endoscopic room to be checked.

[0006] 2、传统耳鼻喉镜使用前必须经过高温高压或浸泡消毒,其最短消毒时间不能低于半个小时。 [0006] 2, before using the conventional mirror ENT autoclaving or immersion sterilization, disinfection period which is not less than half an hour. 门诊患者多,一个患者检查完成后,另一位往往要等很长时间才能进行检查,有的患者甚至需要提前好几天预约才可能轮到检查,时效性很差。 Outpatient and more, after a patient examination is completed, another often have to wait a long time to be checked, and some patients even require several days in advance booking it may turn checks, timeliness is poor.

[0007] 3、起雾:由于鼻喉腔道存在大量的人体水蒸气,传统窥镜的光学传像镜面表层容易凝结水气,形成雾层,因此其使用前用加热至六十度左右的生理盐水(浸泡液不能重复使用)浸泡镜体部分十几分钟后再进入人体进行观察,但时间一长镜体温度下降后仍不能避免起雾;还有的防雾方法是防雾剂的使用,但价格昂贵,使用成本高,且不方便。 [0007] 3, fog: The presence of numerous human larynx nasal passage of water vapor, the optical transfer surface of a conventional endoscope specularly readily condensed water vapor, the formation of fog layer, which is heated before use to about 60 degrees physiological saline (steep liquor can not be reused) immersion lens body portion into the body after ten minutes was observed, but the temperature decrease over time scope fog still can not be avoided; antifogging there is to use the anti-fogging agent , but expensive, high cost, and inconvenient.

[0008] 4、有一些病人在做气管插管的时候,由于病人本身气道结构的特殊或者气管异物的存在,造成插管难度增加,这时候需要有可视喉镜或支气管镜的帮助,但目前市场上这两种产品价格很高,而科室的使用率又很低,所以一直没有一个价格适当,又能满足使用需要的设备。 [0008] 4, some patients do when endotracheal intubation, due to the existence of special or foreign body airway of a patient itself, resulting in increased difficulty of intubation, this time need help visualize laryngoscope or bronchoscope, but the high price of these two products on the market, and department usage is very low, it has not been a proper price, but also to meet equipment needs.
