As used herein, the singular is intended to include the plural unless the context clearly dictates otherwise. Furthermore, it will be further understood that the terms "comprises" and/or "comprising," when used in this specification, specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof.

For convenience of description, the words "upper", "lower", "left" and "right" in the present application, if any, merely indicate that the device or element referred to in the present application is constructed and operated in a particular orientation, and thus should not be construed as limiting the present invention, since they are merely intended to be oriented in the upper, lower, left and right directions of the drawings themselves, and not to limit the structure, but merely to facilitate the description of the invention and to simplify the description.

Term interpretation section: the terms "mounted," "connected," "fixed," and the like in the present invention are to be understood in a broad sense, for example, they may be fixedly connected, detachably connected, or integrated; the two components can be connected mechanically, directly or indirectly through an intermediate medium, or connected internally or in an interaction relationship, and those skilled in the art can understand the specific meaning of the above terms in the present invention according to specific situations.

As mentioned above, in the oral and maxillofacial surgery, a large flap is often required to be turned up to expose the operation field, and wound exudate is required to be drained after the operation to avoid complications such as effusion infection. Therefore, the utility model provides a disposable medical closed wound exudate drainage device and components thereof; the invention will now be further described with reference to the drawings and specific examples.

Referring to fig. 1, a disposable medical closed wound exudate drainage device comprises: a flexible drainage tube 1, a puncture needle 2 and a flexible drainage strip 3. The flexible drainage tube 1 is a tubular structure (the inner diameter is 5mm, the outer diameter is 7mm, the wall thickness of the tube is 1mm) made of silicon rubber, both ends of the flexible drainage tube are open, the puncture needle 2 is arranged at the right end of the flexible drainage tube 1, and the puncture needle and the flexible drainage tube are in interference fit; because the flexible drainage tube 1 has certain elasticity, when the puncture needle 2 is inserted into the port of the flexible drainage tube 1, the tight connection between the puncture needle and the flexible drainage tube can be realized, and the falling off is avoided. A plurality of flexible drainage strip 3 bonds on the left end outer wall of flexible drainage tube 1, and is provided with scale mark 4 on flexible drainage strip 3 (wide 5mm, long 10cm, except that the partial length of bonding on flexible drainage strip 1), the scale mark distributes along the length direction of drainage strip, and the interval between the adjacent scale mark is 1 cm. Drainage hole 5 has still been seted up to the 5cm within range of left end of flexible drainage tube 1, and the drainage hole is located and is fixed with the region beyond flexible drainage strip 3, and the drainage hole helps improving drainage efficiency, avoids simultaneously because of the drainage tube tip is blockked up the problem of unable drainage by the hydrops. In addition, the flexible drainage tube 1 is provided with marking lines 6 at positions 5cm and 10cm away from the end part of the flexible drainage tube, and when the marking lines are arranged at the positions 5cm, the marking lines are used for marking dead points of distribution ranges of drainage holes, so that the situation that the holes are exposed outside a wound and negative pressure cannot play a role is avoided. A 10cm mark line is used to mark the approximate length of the drainage tube within the wound bed.

Further, referring to fig. 2, in other embodiments, one end of the flexible drainage strip 3 extends to the area of the drainage hole 5, and one end of the flexible drainage strip 3 is fixed on the flexible drainage tube 1, so that effusion can flow to the area of the drainage hole 5 along the drainage strip to achieve a better drainage effect.

Further, referring to fig. 3, in other embodiments, one end of the flexible drainage strip 3 passes through the area of the drainage hole 5 and extends to the marking line 6 at 5cm, and one end of the flexible drainage strip 3 is fixed on the flexible drainage 1. Similarly, the drainage strip can be used for facilitating the effusion to flow to the area where the drainage holes are positioned along the drainage strip, and the drainage effect is better.

It should explain, when being fixed with a plurality of flexible drainage strips 3 on flexible drainage tube 1, as long as the drainage strip does not all drainage holes all seal, then can not lead to the problem of unable drainage, can be rather because the edge of drainage strip is closer to and stays the sky, more is of value to the hydrops and is inhaled by the drainage hole, promotes the drainage effect.

Further, in other embodiments, the outer surface of one end of the puncture needle 2 is provided with threads, and the one end of the puncture needle refers to one end for connecting with the flexible drainage tube 1. This further helps to prevent the puncture needle from falling out of the drainage tube during the skin puncture.

Further, in other embodiments, the outer wall of the flexible drainage tube 1 and the flexible drainage strip 3 are provided with marking lines which can be developed under X-ray irradiation, and the marking lines are distributed along the length direction of the drainage tube or the drainage strip, if the drainage strip or the drainage tube is pulled out, a part of the marking lines is left in the wound due to breakage and the like, and the marking lines can be detected by X-rays, so that the marking lines can be taken out conveniently. It should be noted that the flexible drainage tube 1 and the flexible drainage strip 3 may also be made of other materials, such as the flexible drainage tube 1 made of a polyethylene tube, and the rubber drainage strip made of rubber.

Further, in view of avoiding the flexible drainage tube from being blocked to affect drainage, in some embodiments, the flexible drainage strips 3 are distributed along the circumference of the outer wall of the flexible drainage tube 1, and the flexible drainage strips 3 are tightly adhered to the outer wall of the flexible drainage tube 1. When the disposable medical closed wound exudate drainage device is used, the device is required to be matched with a negative pressure device, and a connecting pipe of the negative pressure device is connected with a drainage pipe.

When the disposable medical closed wound exudate drainage device and the components thereof are used for drainage, firstly, after the puncture needle penetrates through the skin, the drainage strip and the drainage tube distributed with the drainage hole part are left in the wound and the wound is fixed, then the puncture needle is pulled out of the drainage tube, and the drainage tube is connected with the connecting tube of the negative pressure drainage device to play a role in negative pressure drainage. When drainage strip and drainage tube need be demolishd, can check whether thoroughly take out the drainage strip according to above scale, when not all taking out, explore the position of remaining drainage strip through the X line, be convenient for take out it.

Finally, it should be understood that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention. Although the present invention has been described with reference to the accompanying drawings, it is not intended to limit the scope of the present invention, and those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without inventive work are still within the scope of the present invention.
