The adjustable negative pressure drainage bottle comprises a drainage bottle, a drainage pipe and a guide needle, wherein the top of the drainage bottle is provided with a liquid inlet; the liquid inlet is provided with a sealing clip and is connected with a Luer; one end of the drainage pipe is connected with the Luer by a Luer taper; the tail end of the guide needle is connected with a guide pipe; the guide pipe is connected onto a Y-shaped tee joint arranged at the other end of the drainage pipe; the Luer taper is provided with a one-way valve; the drainage pipe is provided with a negative pressure release regulator capable of changing the cross sectional area of the drainage pipe. The adjustable negative pressure drainage bottle has the advantages of 1, being capable of resisting countercurrent and preventing infection; 2, having the advantages of a high-negative-pressure drainage bottle and a low-negative-pressure drainage bottle in the prior art.

Description

The adjustable negative pressure drainage bottle

Technical field

This utility model relates to a kind of adjustable negative pressure drainage bottle, belongs to the medical apparatus technical field.

Background technology

At present, drain use clinically is more and more, facts have proved, the liquid in crack, body cavity, internal organs organ pipe of organizing of human body is deflected to original place or excretes, need to realize by negative pressure drainage in most cases, negative pressure drainage has also obtained abundant affirmation in clinical practice.At first, hospital adopts central negative pressure to attract, and its maximum defect is exactly dumb, and the patient must can not arbitrarily walk about by hospital's negative pressure system, in the poor hospital of some medical conditions and field, can not realize at all.In order to address this problem, people have developed negative pressure drainage vessel, exactly the gateway of a container is blocked, after by external negative pressure device, attracting, make in container to form negative pressure, be equipped with as apparatuses such as guid needle, guide wires again, just formed an easy drainage system, the negative pressure drainage vessel that namely uses clinically now.

Mainly there is following defect in existing negative pressure drainage vessel: 1, adverse current easily occurs, can not protect from infection, in case when in bottle inversion or bottle, liquid level was too high, infection risk was very high; 2, existing negative pressure drainage vessel has two kinds of high negative pressure and lower negative pressures, high negative pressure drainage bottle have attract fully, can cicatrize a wound rapidly, the drain liquid measure can reach drainage bottle capacity 85% with first-class advantage, in the clinical practice for some sufferer, obtained certainly, as the fracture etc., yet, not all sufferer all is suitable for high negative pressure drainage bottle, as operation negative pressure value such as hyperthyroidisms, requires in not too high operation; And in clinical practice, find, the drain of most of sufferers preferably first attracts with high negative pressure, then attracts with lower negative pressure, still, existing negative pressure drainage vessel all can not realize that negative pressure is adjustable, use very inconvenience.

The utility model content

The purpose of this utility model is, a kind of adjustable negative pressure drainage bottle is provided, to solve above-mentioned technical problem.

For addressing the above problem, the technical scheme that this utility model adopts is:

A kind of adjustable negative pressure drainage bottle, comprise drainage bottle, drainage tube and guid needle; The top of described drainage bottle is provided with inlet, on described inlet, clips is installed, and is connected with female Luer; One end of described drainage tube is connected with female Luer by female Luer; The end of described guid needle is connected with guide wire, and guide wire is connected in the Y shape threeway on the drainage tube other end; It is characterized in that: on described female Luer, be provided with check valve; The negative pressure release regulation device that can change the drainage tube cross-sectional area is installed on described drainage tube.

Say further:

The top of described drainage bottle is equipped with negative pressure display and/or negative pressure show rulers.

On described guide wire, be provided with the guide wire fixture.

Beneficial effect: compared with prior art, the utlity model has following advantage: 1, the female Luer on drainage tube is with check valve, neither affects external negative pressure device and forms negative pressure in bottle, attracting, and can solve again bottle interior liquid countercurrent and causes the problem of infection; 2, the cross-sectional area that changes drainage tube by being arranged on negative pressure release regulation device on drainage tube is controlled the size of negative pressure, and then regulates the release of negative pressure, makes the advantage of this utility model with high negative pressure drainage bottle in prior art and lower negative pressure drainage bottle.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

With reference to Fig. 1, adjustable negative pressure drainage bottle described in the utility model, comprise drainage bottle 1, drainage tube 8 and guid needle 13.The top of described drainage bottle 1 is provided with inlet 4, on described inlet 4, clips 7 is installed, and is connected with female Luer 6.One end of described drainage tube 8 is connected with female Luer 6 by female Luer 5, on described female Luer 5, is provided with check valve, like this, neither affects external negative pressure device in bottle, attract forming negative pressure, can solve again bottle interior liquid countercurrent and causes the problem of infection.

The end of described guid needle 13 is connected with guide wire 11, and guide wire 11 is connected in the Y shape threeway 10 on drainage tube 8 other ends; On described guide wire 11, be provided with guide wire fixture 12.The negative pressure release regulation device 9 that can change drainage tube 8 cross-sectional areas is installed on described drainage tube 8.By the cross-sectional area that negative pressure release regulation device 9 changes drainage tube 8, control the size of negative pressure, and then regulate the release of negative pressure.

In order to make the medical worker can in time learn the negative pressure value size in drainage bottle 1, the top of described drainage bottle 1 is equipped with negative pressure display 2 and/or negative pressure show rulers 3.

During drainage procedure, the doctor first is embedded in by guid needle 13 pathological area that needs drain, after by guide wire fixture 12, guide wire 11 being fixed on to body surface, being connected in Y shape threeway 10, then female Luer 5 is connected with female Luer 6; Then, clips 7 is unclamped.Like this, just between the pathological area that needs drain and the drainage bottle 1 with negative pressure, just formed an airtight subnormal ambient, under the vacuum suction effect, body fluid is drained in drainage bottle 1.
