Below difference with the prior art of the present invention is elaborated.
The negative pressure drainage of existing clinical use mainly contains three kinds of modes:
1, directly uses Negative pressure machine or HC negative pressure, hold attraction operation with continuing.This mode can accurately be adjusted to the negative pressure 0Kpa-80Kpa of clinical needs, and it can satisfy most of clinical demand, but the shortcoming of its existence is not removable, because need continual attraction under a lot of situations during closed drainage.
2, adopt the negative pressure drainage ball, utilize elastic deformation to produce negative pressure, realize negative pressure drainage.The negative regulation of negative pressure drainage ball, easy to carry, but that its shortcoming is negative pressure is single, range of negative pressure is less, to about the 20Kpa, and the negative pressure show value is inaccurate at 0Kpa.
3, use the closed drainage bottle that presets negative pressure, it utilizes the negative pressure that presets in the bottle to realize negative pressure drainage.Negative pressure drainage vessel is easy to carry, negative pressure is high, but shortcoming is the negative pressure instability, and the negative pressure that presets can constantly decay until not having; Secondly be exactly that Cao Zuo negative pressure reaches 85Kpa-90Kpa at the beginning, thereby is not suitable for most of closed drainage.
The technical scheme that these three kinds of existing modes and the present invention the are taked analysis of tabulating now:
As can be known from the above table, the disposable negative pressure drainage vessel of the present invention can be accomplished the negative pressure that provides lasting, accurate, stable, and can regulate exactly, and can be portable.
