Specific embodiment
Specific embodiments of the present invention are described in further detail below in conjunction with attached drawing:
As shown in Fig. 1 ~ Fig. 2, anti-suck negative pressure drainage vessel, including device bottle body 1 is provided on described device bottle body 1 negative
Potential source connection component 2 and the draining hole 3 being connected to bottle body 1.1 top of described device bottle body is provided with liquid barrier 5, the liquid barrier
5 form closed area at the top of bottle body 1, and 5 two sides of liquid barrier are respectively equipped with negative pressure guide port 6 and negative pressure liberation port 7, described
Negative pressure source connection component 2 is sealedly and fixedly connected with negative pressure guide port 6, so that negative pressure source interface and liquid barrier 5 are in 1 top shape of bottle body
It is connected at closed area.Liquid barrier 5 forms closed area at the top of bottle body 1, and negative pressure source connection component 2 and negative pressure guide port 6
It is sealedly and fixedly connected, is connected to so that negative pressure source interface forms closed area with liquid barrier 5 at the top of bottle body 1, cleverly ties in this way
Structure design can form closed area, effective protection negative pressure source connection component 2, drainage-fluid meeting by liquid barrier 5 at the top of bottle body 1
It is blocked by liquid barrier 5, negative pressure source connection component 2 will not be entered.
It is because caused by three kinds of situations that suck-back, which occurs, for general drainage bottle, i.e., bottle body 1 is arranged to negative pressure source connection component 2
Side is toppled over, bottle body 1 is toppled over to the side being arranged far from negative pressure source connection component 2, and bottle body 1 shakes.When bottle body 1 is to negative pressure
When the side that source connection component 2 is arranged is toppled over, drainage-fluid can be sheltered from by liquid barrier 5, when bottle body 1 is to far from negative pressure source connection group
When the side that part 2 is arranged is toppled over, drainage-fluid can form citadel at the top of bottle body 1 from negative pressure liberation port 7 into liquid barrier 5
Domain, however negative pressure source connection component 2 is located at the top of closed area at this time, the opening of negative pressure liberation port 7 of bottom is smaller, and drainage-fluid is only
It can slowly enter, will not have top, cause suck-back, when bottle body 1 shakes, liquid barrier 5 is fully able to shelter from drainage-fluid,
It is avoided to enter negative pressure source connection component 2.
In order to further effectively will between drainage-fluid and negative pressure source barrier open, the negative pressure source connection component 2 can be used with
It is provided with opening in flowering structure, including seal casinghousing 2a and negative pressure source interface 2b, the seal casinghousing 2a, which leads with negative pressure
Draw mouth 6 to be sealedly and fixedly connected, the ventilative filler of resistance bacterium blocking solution is provided in the seal casinghousing 2a.Such design, in negative pressure source
And liquid barrier 5 forms the design for foring a closed cavity between closed area again, and internal setting resistance at the top of bottle body 1
Bacterium blocking solution is breathed freely filler, even if accidentally, having a small amount of drainage-fluid to enter negative pressure source connection component 2 by negative pressure guide port 6, also capable of
It is enough to be separated by the ventilative filler of resistance bacterium blocking solution, guarantee being perfectly safe for negative pressure source.
In the case where negative pressure liberation port 7 can be flooded in order to which after bottle body 1 is toppled over, drainage-fluid is more in bottle body 1, effectively
Delay drainage-fluid to enter the time of negative pressure source connection component 2, further provides protection to negative pressure source connection component 2；The bottle body 1
Top is provided with the airtight chamber 4 of assembly negative pressure source connection component 2, the side that the negative pressure source connection component 2 is connected to bottle body 1
It is fixedly mounted in airtight chamber 4, is provided with opening at the top of the airtight chamber 4, the opening and the sealing of negative pressure guide port 6 are fixed
Connection.Such design increases a closed cavity again in 2 outside of negative pressure source connection component, when bottle body 1 is to far from negative pressure source
When the side that connection component 2 is arranged is toppled over, drainage-fluid forms citadel at the top of bottle body 1 from negative pressure liberation port 7 into liquid barrier 5
Domain after flooding negative pressure liberation port 7, can enter in the closed cavity, negative pressure source connection group can just be entered by gradually filling up after the cavity
Part 2, is equal to drainage bottle provided with triple protection, almost being capable of 100% generation for avoiding suck-back.To simplify structure, convenient for system
It makes, is constituted at the top of the airtight chamber 4 for a part of liquid barrier 5, the negative pressure guide port 6 opens up on the portion.
The liquid barrier 5 preferably arranges that the side for opening up negative pressure liberation port 7 on the lower, opens up negative pressure and leads using angled manner
The side for drawing mouth 6 is top.So, enter after liquid barrier 5 forms closed area at the top of bottle body 1 in drainage-fluid, as long as bottle
The drainage-fluid of 1 righting of body, entrance can flow out again.
The settable indent in region of negative pressure source connection component 2 and draining hole 3 is arranged in the bottle body 1, forms interior recessed area.In this way
It can guarantee that the bottle body 1 of drainage bottle does not protrude part, not have sense of discomfort when patient carries.
5 two sides of liquid barrier can be connected with 1 two sides of bottle body, form the closed area at entire 1 top of bottle body of a sealing,
The negative pressure guide port 6 is provided with the one side edge of liquid barrier 5, and the negative pressure liberation port 7 is provided with another side of liquid barrier 5
Edge.In this way, liquid barrier 5 has enough width, entire 1 top of bottle body can be sealed.When bottle body 1 is to far from negative pressure source connection group
When the side that part 2 is arranged is toppled over, drainage-fluid forms closed area at the top of bottle body 1 from negative pressure liberation port 7 into liquid barrier 5, i.e.,
So that drainage-fluid is almost stored up full drainage bottle, topples over rear negative pressure guide port 6 and be just located at 1 top of bottle body, drainage-fluid does not have never
At to this.
Liquid barrier 5 can be used multiple structural forms, and also there are many structures for the opening of negative pressure guide port 6 and negative pressure liberation port 7.
