Description
Technical field
The utility model belongs to field of medical appliances, particularly to one disposable constant volume negative pressure drainage device.
Background technology
At present, negative-pressure sealed drainage technology (being called for short VSD) tends to ripe, and it has the effect to complicated wound repair.Its
In, VSD refers to, with the medical sponge dressing including drainage tube, cover or fill the surface of a wound of skin, soft tissue defects, then with raw
It is closed by thing semi-transparent film so that it is become a confined space, finally drainage tube is connected central negative potential source, by can
The negative pressure controlled carrys out a kind of brand-new methods for the treatment of of wound healing.
During the use of VSD, medical personnel need to observe situation, the workload of increase medical personnel:
1, change every day or clean drainage bottle, preventing drainage bottle overfill, drainage bottle overfill from liquid can be caused to suck central negative
Potential source or Electric negative pressure source, damage machine.
2, be sucked out with or without a large amount of new bloods, if find new blood, should in time closing center's negative pressure source or electronic bear
Potential source.
Utility model content
The utility model is to provide a kind of disposable constant volume without medical personnel's nurse, suction body fluid capacity controllable to bear
Pressure drainage system.
For achieving the above object, the technical solution of the utility model is as follows:
Including drainage bottle, bottle cap and ball float, drainage Bottle and bottle cap is adaptive, and bottle cap is provided with first interface and the second interface,
Connecing drainage tube in second interface, drainage tube connects that to have water conservancy diversion interface, described water conservancy diversion interface to be set to up-narrow and down-wide to funnel type,
Ball float is positioned at drainage bottle, and floating ball diameter is less than drainage tube diameter.
For making ball float under the effect of negative pressure source, stopping at drainage tube and the second interface, thus block negative pressure source, ball float is straight
Footpath is more than or equal to the second interface diameter.
For filtering the impurity in drainage bottle, in order to avoid damaging negative pressure source, the second external filtering cover of interface.
In order to liquid (such as water for injection) adding drainage bottle to control the body fluid volume that can suck in drainage bottle, this practicality is newly
Type also includes funnel, and funnel is adaptive with first interface, for liquid is poured into drainage bottle.
In order to aspect medical personnel are starting to observe after drainage the color liquid measure of patient's drainage-fluid, and in time, accurately measure
The capacity of drainage-fluid, described drainage bottle bottle is transparent or semitransparent material, and described drainage bottle bottle is provided with scale.
For ball float position, location, making ball float accurately enter water conservancy diversion interface, be additionally provided with conduit in drainage bottle, conduit is through to be drawn
Stream bottle, described catheter containment drainage tube, water conservancy diversion interface and ball float；For making drainage-fluid enter in conduit, described duct wall sets
Put some apertures；For convenience of adjusting drainage tube and leading connector and carry out predetermined safe range drainage liquid measure from height at the bottom of bottle, described in lead
Also with scale on tube wall.
The utility model has by arranging ball float so that stop negative pressure to continue when the drainage-fluid in drainage bottle reaches preset value
Continuous drainage, massive haemorrhage at patient when not only preventing under VSD, pneumothorax drainage, glottis the negative pressure drainages such as drainage, but also anti-
Only in drainage bottle, liquid measure completely causes liquid to be back to negative pressure source, has simple in construction, and easy to operate, safe and reliable, applicability is wide
Feature.

Detailed description of the invention
Embodiment
Disposable constant volume negative pressure drainage device, fits including drainage bottle 10, bottle cap 20 and ball float 50, drainage bottle 10 and bottle cap 20
Joining composition confined space, bottle cap 20 is provided with first interface 21 and the second interface 22, first interface 21 is connected by pipe and suffers from
At person's drainage, in the second interface 22 external connecting negative pressure source (such as: central negative potential source or Electric negative pressure source) the second interface 22, connect drainage
Pipe 23, it is internal that drainage tube 23 is positioned at drainage bottle 10, and drainage tube 23 one end bottom drainage bottle 10 connects water conservancy diversion interface 24,
Described water conservancy diversion interface 24 is set to up-narrow and down-wide (funnel type).(as shown in Figure 3), wherein, drainage tube 23 and water conservancy diversion interface 24
Alternatively being wholely set, ball float 50 is positioned at drainage bottle 10, ball float 50 diameter less than more than drainage tube 23 diameter and more than or etc.
In the second interface 22 diameter, being additionally provided with conduit 25 in drainage bottle 10, the through water-sealed drainage bottle of conduit 25 10, conduit 25 accommodates drainage tube
23, water conservancy diversion interface 24 and ball float.Arranging many places aperture 26 on conduit 25 tube wall, the body fluid in drainage bottle 10 can be existed by aperture 26
The inside and outside circulation of conduit 25, also with scale on conduit 25 tube wall.Filtering cover 40 is set between second interface 22 and negative pressure source, filters
Lid 40 is for the interface filtered, and may filter that the impurity in drainage bottle 10, in order to avoid damaging negative pressure source, disposable constant volume vacuum suction
Drainage bottle also includes funnel 30, and funnel 30 first interface 21 is adaptive, for liquid (such as water for injection) is added drainage bottle 10
With the body fluid volume that can suck in controlling drainage bottle 10.Drainage bottle 10 bottle is transparent or semitransparent material, described drainage bottle 10 table
The scale of blueness or the black conveniently calculating liquid level it is provided with on face.Aspect medical personnel are after starting negative pressure drainage
Observe the color of patient's liquid and liquid measure, and in time, accurately measure the capacity of drainage-fluid.
Principle of the present utility model is: drainage bottle 10 is bled by negative pressure source by the second interface 22, first interface 21
Connecting at patient by pipe, patient's liquid (fester or blood) is inhaled in drainage bottle 10 by first interface 21
Portion, the ball float 50 in drainage bottle 10 floats due to increasing of body fluid, and reaching (can be certain by pouring in advance at water conservancy diversion interface 24
The water for injection measured or the length arranging drainage tube 23 carry out predetermined safe range drainage liquid measure), it is positioned at the floating of conduit 25 simultaneously
Ball 50, under the effect of negative pressure source, enters drainage tube 23 by water conservancy diversion interface 24, until ball float 50 arrives the second interface 22, thus
Make negative pressure source be obstructed and quit work.
