    • There is provided an improvement to a device for slidably mounting a tube against an orifice of a medical patient, the device including a polygonal section of sponge foam, a bore through this foam and a slot for enabling the polygonal section of foam to be slid over and onto a tube. The improvement comprises a rigid backing plate that fixedly attaches to the sponge foam in an area apart from, and preferably opposite, the surface of the sponge foam section in contact with the patient's orifice. This backing plate has a bore and slot corresponding to those in the sponge foam section. With this improvement, such mounting devices may be placed in more permanent traction against the patient's nose, mouth or other orifice. A further improvement includes a gauge for varying the amount of substantially permanent traction placed on a medical tube with this device. There is also disclosed a method for supplying variable amounts of substantially permanent traction to a medical tube with the holder of this invention.
    • 提供了一种用于将管可滑动地安装到医疗患者的孔口上的装置的改进,该装置包括海绵泡沫的多边形部分,穿过该泡沫的孔,以及用于使多边形部分的泡沫能够滑过的狭槽 并放在管子上。 该改进包括刚性背板,其在与患者孔口接触的海绵泡沫部分的表面之外的区域(优选相对的)上固定地附接到海绵状泡沫体。 该背板具有对应于海绵泡沫部分中的孔和槽。 通过这种改进,这种安装装置可以被放置在更持久的牵引力下,抵靠患者的鼻子,嘴部或其他孔口。 进一步的改进包括用该装置改变放置在医疗管上的基本上永久牵引的量的量规。 还公开了一种用于向具有本发明的保持器的医用管提供可变量的基本永久牵引的方法。
