Abstract

The utility model discloses an anti-reflux multifunctional drainage joint which comprises a drainage tube joint (1). The front end of the drainage tube joint (1) is a drainage tube discharging connector (2). The rear end of the drainage tube joint (1) is a drainage bag discharging connector (3). A one-way valve (4) is arranged on a position, near the drainage bag discharge connector (3), of the drainage tube joint (1). The drainage joint effectively prevents high-level liquid from reversely flowing so that a source of retrograde infection in a drainage cavity of a patient is cut off, probability of the retrograde infection is greatly reduced, drainage tube wash or drainage liquid sample collection is conducted under a closed environment all the time, occurrence of the retrograde infection is further effectively avoided, tightness of the whole drainage joint is good, replacing time of a drainage bag is prolonged, pain of the patient is lightened, waste of health resources is reduced, structure is simple, practicability is strong and the anti-reflux multifunctional drainage joint can be easily and clinically popularized and applied.

Description

The multi-functional flow sub of a kind of counterflow-preventing

Technical field

This utility model belongs to field of medical products, is specifically related to a kind of flow sub.

Background technology

The existing clinical drainage tube that generally uses, the one end is the drain end, and the other end is inserted the drain end in the patient body during use for the excretion interface, and the excretion interface is at external connection drainage bag; And the existing clinical drainage bag that generally uses is single hose, and its front end is drainage catheter, and the rear end is liquid-collection bag, the drainage tube endoceliac liquid of drain that is connected with drainage bag.

Above-mentioned drainage tube directly is connected with drainage bag, mainly has following shortcoming:

(1) drainage tube directly communicates with drainage bag, and during higher than the drain position, in drainage bag, the easy adverse current of liquid causes retrograde infection to patient's drainage lumens when the drainage bag position.

(2) joint that must separate drainage tube and drainage bag during blocked drainage tube just can be rinsed.This open flushing has increased the chance that the drainage tube inner chamber pollutes, thereby causes the generation of retrograde infection.

When (3) the collection drainage-fluid is done the antibacterial cultivation, must separate drainage tube and drainage bag ability specimen taken.Although anti back-flow arrangement is also arranged at present, common product is the anti back-flow drainage bag, but it can not block the adverse current of liquid in drainage catheter, and when blocked drainage tube maybe need gather the drainage-fluid specimen, still need separate drainage tube and drainage bag joint, thereby increase the chance of retrograde infection.

The utility model content

For above-mentioned deficiency, this utility model provides a kind of can effectively prevent high-order liquid countercurrent, reduce to infect probability, and seal multi-functional flow sub preferably.

This utility model is to realize by such technical scheme: the multi-functional flow sub of a kind of counterflow-preventing, comprise drainage tube joint, the front end of this drainage tube joint is drainage tube excretion interface, the rear end is drainage bag excretion interface, wherein, drainage tube joint is arranging a flap valve check valve near drainage bag excretion seam.

Described drainage tube joint arranges a perforate on the tube wall near drainage tube excretion interface, and in this perforate, a puncture component is set, as the passage of flow sub inner chamber with the external world.

Further that the two ends of described drainage tube joint are all tapered.

Further that the big or small 1cm of distance of described flap valve check valve and drainage bag excretion interface preferably approximates 1cm.

Further that the distance of described perforate and drainage tube excretion interface preferably approximates 2cm less than 2cm.

Further that described puncture component is positioned at the place ahead of flap valve check valve.

Owing to having adopted said structure, the beneficial effects of the utility model are as follows: drainage tube joint is arranging a flap valve check valve near drainage bag excretion seam, effectively prevent high-order liquid countercurrent, cut off the source of retrograde infection in patient's drainage lumens, greatly reduced the probability of retrograde infection; And, on the tube wall near drainage tube excretion interface, a perforate and puncture component are set, as the inner chamber of flow sub and extraneous passage, from need not to separate drainage tube and drainage bag can be obtained specimen, drainage tube flushing or drainage-fluid collection of specimens are carried out under airtight environment all the time, further effectively prevent the generation of retrograde infection, the good leak tightness of whole flow sub, can extend the replacing time of drainage bag, service time is long, alleviates patient's misery, reduced the waste of health resources, it is simple in structure, and is practical, is easy to clinical application.

Description of drawings

Fig. 1 is the structure diagram of the multi-functional flow sub of the described counterflow-preventing of this case.

The specific embodiment

In order more to be expressly understood the purpose of this utility model, technical scheme and beneficial effect, below in conjunction with accompanying drawing, this utility model is described further, but protection domain of the present utility model is not limited in following examples.

As shown in Figure 1, the multi-functional flow sub of a kind of counterflow-preventing, comprise drainage tube joint 1, the front end of this drainage tube joint 1 is drainage tube excretion interface 2, the rear end is drainage bag excretion interface 3, and wherein, drainage tube joint 1 is arranging a flap valve check valve 4 near drainage bag excretion interface 3 places, in order to prevent liquid countercurrent in high-order liquid or drainage bag to patient's drainage lumens, cause retrograde infection; Described drainage tube joint 1 arranges a perforate 5 on the tube wall near drainage tube excretion interface 2, and the interior puncture component 6 that arranges of this perforate 5, as the passage of flow sub inner chamber with the external world, so that the flushing of drainage tube or collection of specimens are all carried out in airtight system, protect from infection; The two ends of described drainage tube joint 1 are all tapered; The big or small approximately 1cm of distance of described flap valve check valve 4 and drainage bag excretion interface 3; The distance of described perforate 5 and drainage tube excretion interface 2 is less than about 2cm; Described puncture component 6 is positioned at the place ahead of flap valve check valve 4.
