Second, by arranging the spring 3 of specific coefficient of elasticity, diaphragm 2, guide pillar 2a, and on tubular case
Offering compensation gas port 8, the elastic force of spring is linear with deflection, when bearing of negative pressure source interface 1
When pressing relatively low, the elastic force of spring 3 props up diaphragm 2, compensation gas port 8 is blocked, and maintains setting
Negative pressure；When the negative pressure of negative pressure source interface 1 is higher, negative pressure overcomes partial spring pressure, diaphragm 2 to put
Pine, outside air compensates and enters, reduces and attract negative pressure.Achieve and set being automatically adjusted of negative pressure.
Further, described one group of compensation gas port 8 is with tubular case end face center as the center of circle, in ring
Shape is arranged, diaphragm 2 is ring-type in correspondence.
Further, described pore 5a, with the center of base plate 5 as the center of circle, is circular layout in a circle, institute
State the traffic sign placement of projection at the middle part of a circle pore 5a.
Further, the described top being arranged on tubular case when negative pressure source interface 1, described body is even
Interface is arranged on the bottom of tubular case.
The beneficial effects of the present invention is:
1) can significantly distinguish negative pressure whether to open, it is simple to medical personnel control water-sealed drainage bottle work in real time
Situation.
2) realize automatization's regulation of negative pressure, improve the convenience of negative pressure regulation.
3) improve the reliability of water-sealed drainage bottle work.
4) simple in construction, compact, the top of water-sealed drainage bottle can be arranged on.
5) implementing conveniently, to put into less, cost is relatively low, and beneficial effect is notable.

Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the present invention is further described.
Seeing Fig. 1-5, a kind of water-sealed drainage bottle is automatically adjusted negative pressure device, including tubular case, described tubular
Case is provided with negative pressure source interface 1, body connector, and tubular case one end is offered one group and compensated gas port
8；Tubular casing interior is provided with sleeve 4, is provided with the spring 3 of diaphragm 2, specific coefficient of elasticity in sleeve 4；
Described diaphragm 2 with compensate fit at gas port 8 corresponding, in the middle part of diaphragm 2 band guide pillar 2a, guide pillar 2a and
Spring 3 one end is socketed, and the spring other end props up sleeve 4；Base plate 5 is provided with pore 5a and projection
Mark, base plate 5 is outside fits corresponding with transparent membrane 6；Also include that end cap 7, described end cap 7 have
Form 7a, form 7a are corresponding with transparent membrane 6 position；When negative-pressure sucking is opened, transparent membrane 6
It is close to base plate 5 under the suction of pore 5a, finds out, from form 7a, the mark highlighted base plate 5；
When the negative pressure of negative pressure source interface 1 is relatively low, the elastic force of spring 3 props up diaphragm 2, will compensate gas port 8
Block, maintain the negative pressure set；When the negative pressure of negative pressure source interface 1 is higher, negative pressure overcomes part
Spring pressure, diaphragm 2 loosens, and outside air compensates and enters, and reduces and attracts negative pressure.
Seeing Fig. 3, described one group of compensation gas port 8 is with tubular case end face center as the center of circle, ringwise
Arranging, diaphragm 2 is ring-type in correspondence.The stability that diaphragm coordinates with tubular case is high.
Described pore 5a, with the center of base plate 5 as the center of circle, is circular layout in a circle, the mark of described projection
Will is arranged on the middle part of a circle pore 5a.Transparent membrane 6 is conducive to fit tightly with base plate 5, and convex
Aobvious " √ " shape mark, can pass through to judge whether external connecting negative pressure source opens with or without " √ " shape mark,
Simple, intuitive.
The described top being arranged on tubular case when negative pressure source interface 1, described body connector is arranged on
The bottom of tubular case, reasonable structural arrangement.
Present invention is characterized in that first, by being provided with protruding sign and the base plate 5 of pore 5a,
And carry out corresponding transparent membrane 6 with base plate 5, utilize the negative pressure provided at pore 5a, by transparent
The tight adhesive of diaphragm 6, transparent membrane 6 highlights sign, and operation doctor can be obvious from form 7a
Find out that negative pressure is opening, it is simple to instrument situation is controlled by operative doctor in real time；Second,
By arranging the spring 3 of specific coefficient of elasticity, diaphragm 2, guide pillar 2a, and offer benefit on tubular case
Repaying gas port 8, the elastic force of spring is linear with deflection, when the negative pressure of negative pressure source interface 1 is relatively low
Time, the elastic force of spring 3 props up diaphragm 2, compensation gas port 8 is blocked, and maintains the negative pressure set；
When the negative pressure of negative pressure source interface 1 is higher, negative pressure overcomes partial spring pressure, diaphragm 2 to loosen, outward
Boundary's compensated with air enters, and reduces and attracts negative pressure.Achieve and set being automatically adjusted of negative pressure.
