特殊咬口的研制

Development of special einbrand

目的 :针对普通咬口用于吸痰护理的弊端,为临床吸痰研制一种专用咬口。方法 :该咬口由含入口腔的体部和口外的翼部2个部分组成。采用具有自润滑性的材料——聚甲醛制作,以减小操作阻力。体部尺寸小巧,便于置入患者的口中,且能有效压舌;其咬面分为平面和椭圆曲面两段——平面方便被患者齿力咬持,曲面易于咬口的脱卸。咬口在置入时,翼部具有限位作用,并能被单手拿捏以便于操作。结果:经临床吸痰操作,将患者齿缝略开约10 mm,咬口即能被轻松置入;若患者有咬力,咬口能被稳定地咬住;将咬口外移35 mm左右即能依靠患者咬力自行脱卸;咬口能经受压强p>12 kg/cm^2(即1 200 kPa)而无变形。结论:吸痰专用咬口能很好地满足临床使用,适合不同患者的口腔及咽喉部吸痰护理工作。

Objective To develop a kind of special einbrand for clinical sputum suction.Methods The einbrand was composed of two parts:a body penetrating the mouth and an external wing,which was made of self-lubrication paraformaldehyde.The body was small in size and easy to be put in the patient's mouth,and could effectively press the tongue.The bite surface was divided into two sections of plane and elliptic surface,the plane section facilitated the biting of the patient while the elliptic surface assisted to discharge the einbrand.The external wing executed positioning while the einbrand was put into the mouth,which could be held by one single hand for manipulation.Results Clinical trials proved that the einbrand was embedded into the mouth easily with the mouth opened 10 mm,that the einbrand was bitten by the patient in case the bite force was existent,that the einbrand was discharged when it was drawn out 35 mm or so,and that the einbrand could withstand the pressure higher than 12 kg/cm2(1 200 kPa)with no deformation.Conclusion The einbrand designed can be satisfactorily used for clinical sputum suction.
