Abstract

The utility model discloses a kind of more drainage tubes, including outer tube and at least 2 inner tubes, said inner tube is arranged in the outer tube and can be free to slide, the limiting device moved horizontally for limiting said inner tube is equipped on the outer tube close to the position of said inner tube, the bottom end of said inner tube is connected to a negative pressure drainage vessel.The utility model is few using the notch of an outer tube, reduces the pain of patient, while time and operating procedure can also be saved in art, simplifies surgical procedure, speeds procedure；Inner tube is fixed simple, easy to adjust, and patient hardly has discomfort when adjusting；Any inner tube is individually pulled out, is not had any impact to other inner tubes.

Description

A kind of more drainage tubes

Technical field

The utility model relates to a kind of more drainage tubes.

Background technique

Drainage tube used at present needs to put one in each drainage point, and larger to patient trauma, notch is more, and Do not allow to be fixed easily, fixed bit postpones again difficult adjusting position, and is not easy to keep sterile.

Utility model content

The utility model devises a kind of more drainage tubes in view of the deficiencies of the prior art.

The utility model is in order to achieve the above object, using following scheme: a kind of more drainage tubes, including outer tube and at least 2 Root inner tube, said inner tube are arranged in the outer tube and can be free to slide, on the outer tube on the position of said inner tube Equipped with the limiting device moved horizontally for limiting said inner tube, the bottom end of said inner tube is connected to a negative pressure drainage vessel.

Further, the limiting device is clip, and the collet of the clip is matched with the diameter of said inner tube.

Further, the shank of the clip is fixed at the two sides of the outer tube wall.

Further, the outer tube is made of soft plastic.

The utility model compared to the prior art, have the following advantages and beneficial effects: it is few using the notch of an outer tube, The pain of patient is reduced, while time and operating procedure can also be saved in art, simplifies surgical procedure, speeds procedure； Inner tube is fixed simple, easy to adjust, and patient hardly has discomfort when adjusting；Any inner tube is individually pulled out, in other Pipe does not have any impact.

Detailed description of the invention

Fig. 1 is the utility model overall structure diagram；

Fig. 2 is that the utility model clip and inner tube cooperate schematic diagram.

Specific embodiment

A kind of more drainage tubes combined with Figure 1 and Figure 2, including outer tube 1 and at least 2 inner tubes 2, said inner tube 2 are arranged in institute It states in outer tube 1 and can be free to slide, close to the position of said inner tube 2 equipped with for limiting said inner tube 2 on the outer tube 1 The limiting device moved horizontally, the bottom end of said inner tube 2 are connected to a negative pressure drainage vessel 3.

As shown in Fig. 2, the limiting device is clip 4, the collet of the clip 4 is matched with the diameter of said inner tube 2, It is formed for two semicircles, it can be with clamping said inner tube 2 when collet closure.The shank of the clip 4 is fixed at described outer The two sides of 1 inner wall of pipe.The outer tube 1 is made of soft plastic.When pressing the two sides of outer tube 1, i.e., clip is pressed through outer tube 1 4 shank can release the limitation to inner tube 2, allow to free up-down stretch and adjust, and after regulating, unclamp clip 4, i.e., It can fix again, be subjected to displacement it no longer.

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change It also should be regarded as the protection scope of the utility model into modification.
