This utility model disposable adjustable continuous negative pressure drainage device comprises transparent vial body, draft regulator, pipette, vacuum table etc., prefabricated 80KPa-98KPa negative pressure in adjustable continuous negative pressure drainage device, under draft regulator effect, liquid sucting port negative pressure arbitrarily can regulate in 0KPa-90KPa, and the negative pressure scale on draft regulator can be adjusted to the negative pressure value needed for liquid sucting port exactly.
Below this utility model and prior art are compared explanation.
The negative pressure drainage of existing Clinical practice mainly contains several mode:
1, directly use Negative pressure machine or HC negative pressure, attract operation constantly.Which accurately can be adjusted to the negative pressure 0Kpa-80Kpa of clinical needs, and it can meet most of clinical demand, but its shortcoming existed is irremovable, because need continual attraction in a lot of situation during closed drainage.
2, adopt 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 its shortcoming to be negative pressure single, range of negative pressure is less, about 0Kpa to 20Kpa, and negative pressure show value is inaccurate.
3, use the closed drainage bottle of preset negative pressure, it utilizes negative pressure preset in bottle to realize negative pressure drainage.Negative pressure drainage vessel is easy to carry, negative pressure is high, but shortcoming is negative pressure instability, and preset negative pressure can constantly decay until do not have; Secondly, the negative pressure operated at the beginning reaches 85Kpa-90Kpa, thus can not be applicable to most of closed drainage.
4, China Patent No. 201320276736.2 discloses a kind of disposable negative pressure drainage vessel, though the patented product has its advantage, it needs to extract required negative pressure with Medical negative pressure machine temporarily, and Clinical practice is convenient not.
Now the technical scheme that these four kinds of existing modes and this utility model are taked is carried out list analysis:
As can be known from the above table, this utility model adjustable continuous negative pressure drainage device can be accomplished to provide lasting, accurate, stable negative pressure, and can regulate exactly, and can be portable, easy to use.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model preferred embodiment is elaborated.
Embodiment 1
See Fig. 1-4, the present embodiment comprises bottle 1, upper cover 2, vacuum table 3, draft regulator 4, pipette 5, base 6, and bottle 1 adopts transparent material to make, and it is suitable for reading is sealed by upper cover 2, and upper cover 2 has sample tap 2-1, and sample tap 2-1 is sealed by rubber.Bottle 1 inserts vacuum table 3, and the upper end of vacuum table 3 is stretched out outside upper cover 2, and is fixed on upper cover 2.
Draft regulator 4 comprises adjustment knob 4-1, spring 4-2, piston 4-3, housing 4-7, and housing 4-7 is cylindric, and housing 4-7 is vertically installed on upper cover 2, is sealed and matched between the two.Regulate the upper end of knob 4-1 to be the handle portion 4-1-1 of oblate shape, its underpart is that the interior hollow section of spinning 4-1-2, the section of spinning 4-1-2 form external screw thread, and the upper end of its housing 4-7 that stretched through also is spun by screw thread.The handle portion 4-1-1 of knob 4-1 is regulated to be in outside upper cover 2.Housing 4-7 built-in piston 4-3, is sealed and matched between the outer wall of piston 4-3 and the inwall of housing 4-7.The inner chamber of housing 4-7 is separated into two cavitys (top be the first cavity, bottom be the second cavity) by piston 4-3, wherein, the sidewall of the housing 4-7 corresponding with the cavity 4-4 of bottom forms liquid sucting port 4-7-1, negative pressure mouth 4-7-2 is formed on bottom, negative pressure mouth 4-7-2 is round table-like, and the inner chamber of negative pressure mouth and bottle 1 is through.
The two ends of spring 4-2 are individually fixed in and regulate the bottom surface of knob handle portion 4-1-1, the upper surface of piston 4-3.
Form the cylinder 4-3-1 of a vertical band arrow (cone shape) in the middle part of the lower surface of piston 4-3, its arrow down, and the shape of the shape of arrow and negative pressure mouth 4-7-2 suitable be that arrow can insert negative pressure mouth 4-7-2 and be sealed.
The liquid sucting port 4-7-1 of housing is communicated with pipette 5.The bottom outer wall of housing 4-7 is also fixedly connected with base 6, and base 6 fixes one end of pipette 5.Pipette 5 stretches out through after upper cover 2, fixes and be sealed and matched between pipette 5 and upper cover 2; Or pipette 5 is divided into two sections, one section is within bottle 1, and another section is in outside bottle 1, and two sections of pipette are connected by upper cover 2 and are communicated with.
Adjustment knob 4-1 is adjusted to desired location, and piston 4-3 up moves under the pulling force effect of spring 4-2, and then makes the cylinder 4-3-1 of its underpart depart from negative pressure mouth 4-7-2 and open negative pressure mouth 4-7-2, is communicated with negative pressure mouth 4-7-2 to make liquid sucting port 4-7-1; When the negative pressure value in cavity 4-4 is greater than set parameter, piston 4-3 moves down until the cylinder 4-3-1 of its underpart inserts negative pressure mouth 4-7-2, to close this negative pressure mouth 4-7-2; When cavity negative pressure value is less than set parameter, piston 4-3 up moves under the effect of spring 4-2, opens negative pressure mouth 4-7-2, thus makes there is stable negative pressure value in liquid sucting port 4-7-1 and cavity 4-4.
