Detailed Description

As shown in fig. 1 to 3, in an embodiment of the drainage device with telescopic function of the present invention, the drainage device comprises a drainage body 10, a first sleeve 20 and a second sleeve 30 slidably sleeved with each other, a drainage head 40, and the like. Through the second end 22 and the third end 31 with first sleeve pipe 20 and second sleeve pipe 30 cup joint with the activity of each other, when patient or other personnel maloperation, the distance of first sleeve pipe 20 and second sleeve pipe 30 can change to avoided whole second sleeve pipe 30 and human keeping somewhere to produce between the pipeline and remove and produce the seepage etc. improved security, reliability, avoided the seepage etc. of maloperation.

Wherein, the drainage body 10 of the drainage device can be a conventional drainage body 10, such as a drainage bag body, a drainage bottle or a negative pressure drainage ball, etc. In this embodiment, the drainage bag body is taken as an example, and the surface thereof may be provided with scale marks or the like. One end of the drainage main body 10 is provided with a drainage inlet 11, and the drainage inlet 11 is connected with the first sleeve 20 in a sealing manner so as to drain liquid (such as effusion, urine, blood and the like) in a human body into the drainage main body 10.

Furthermore, an end of the drainage body 10 away from the drainage inlet 11 is further provided with a discharge port, so that the liquid in the drainage body 10 can be discharged. It will be appreciated that a discharge pipe may be connected to the discharge port, and a discharge valve or the like may be further provided on the discharge pipe to control the discharge. The drainage body 10 can be made of various materials, and when transparent or semitransparent materials are used, scales can be arranged, so that the amount of discharged liquid can be observed conveniently.

The first sleeve 20 includes a first end 21 sealingly connected to the drainage inlet 11 and a second end 22 movably connected to the second sleeve 30. The first end 21 and the drainage inlet 11 can be hermetically connected by various methods such as hot pressing, melting, ultrasonic welding, splicing and the like, so as to collect drainage liquid into the drainage device. It is understood that the first cannula 20 and the drainage body 10 can also be formed by one piece.

The second sleeve 30 includes a third end 31 movably sleeved with the second end 22, and a fourth end 32 hermetically connected with the drainage head 40. The fourth end 32 and the drainage head 40 can be hermetically connected by various methods such as hot pressing, melting, ultrasonic welding, plugging and the like, and connected with a drainage tube extending into the body of a patient through the drainage head 40, and drainage liquid is introduced into the first sleeve 20 through the second sleeve 30 and then flows into the drainage main body 10. It will be appreciated that the second cannula 30 and the drainage head 40 may also be formed as a single piece.

In this embodiment, as shown, the outer diameter of the first sleeve 20 is smaller than the inner diameter of the second sleeve 30, and the second end 22 is removably inserted into the third end 31. In use, the first and second cannulae 20, 30 are connected to the patient's drain in a compressed state, as shown in FIG. 2; when the patient or other person carelessly pulls the drainage body 10, the first sleeve 20 can move in the second sleeve 30, and before the maximum movement position is reached (as shown in fig. 3), the second sleeve 30 and the drainage tube are not displaced greatly, so that the drainage tube is prevented from moving or falling out, and the safety is improved.

Further, a separation prevention structure may be further disposed between the second end 22 and the third end 31 of the first sleeve 20 and the second sleeve 30, so as to prevent the first sleeve 20 and the second sleeve 30 from separating from each other. In this embodiment, the anti-slip structure includes an outer flange 23 extending outward from the end of the second end 22, and an inner flange 33 extending inward from the end of the third end 31. The first and second ferrules 20 and 30 are prevented from disengaging by the snap-fit engagement of the outer flange 23 with the inner flange 33. It will be appreciated that the first and second sleeves 20, 30 may be formed of a flexible material such as plastic or silicone to facilitate nesting of the two and to facilitate deformation for ease of use.

It will be appreciated that in another embodiment, the outer diameter of the first sleeve 20 is greater than the inner diameter of the second sleeve 30, and the second end 22 is removably received about the third end 31. The anti-dropping structure comprises an outer flange 23 extending outwards from the end of the third end 31 and an inner flange 33 extending inwards from the end of the second end 22. The outer flange 23 engages the inner flange 33 to prevent the first and second ferrules 20 and 30 from disengaging.

Further, a flow control switch may be disposed on the first sleeve 20 and/or the second sleeve 30, and the flow control switch may be used to control the flow rate of the fluid.

In some embodiments, the drainage device further comprises a telescoping tube 50 sealingly disposed about the first and second tubes 20, 30. The two ends of the telescopic tube 50 are fixedly and hermetically connected with the outer walls of the first and second tubes 20 and 30, respectively. The extension of the telescopic tube 50 is greater than the maximum distance that the first and second tubes 20, 30 can move relative to each other. The telescoping tubes 50 may be corrugated tubing, elastic hose, or other variable length tubing.

Because this telescopic tube 50 cover is established in first sleeve 20 and second sleeve 30 periphery, even first sleeve 20 and second sleeve 30's hookup location department produces the seepage, also can be shielded by telescopic tube 50, avoids overflowing the polluted environment, further improvement its practicality and reliability.
