[0004] However, the drainage tube in the above technology still has the following problems:

[0005] After the drainage tube is inserted into the patient's body, it is necessary to regularly check the real-time status of the patient's insertion position and promptly deal with the infection at the insertion position to avoid infection and deterioration. However, after the fixed structure fixes the drainage tube, the drainage tube cannot be moved again, which creates certain obstacles to the inspection work of the drainage tube. Utility Model Content

[0006] In view of the deficiencies of the prior art, the utility model provides a drainage tube with a fixing function, such as: when necessary, the fixing structure can be appropriately moved on the drainage tube to facilitate inspection of the drainage tube.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] See also Figure 1 - Figure 6 A drainage tube with a fixing function comprises an adhesive plate 1 and a drainage tube body 2, a glue layer is provided on one side of the adhesive plate 1, a tightening mechanism is connected to the side of the adhesive plate 1 away from the glue layer, the tightening mechanism comprises a shrinking sleeve 3, a shrinking spring 4, a shrinking rod 5 and a pipe sleeve 6, the shrinking sleeve 3 is fixedly connected to the side of the adhesive plate 1 away from the glue layer, the outer wall of the shrinking rod 5 is slidably connected to the inner wall of the shrinking sleeve 3, the two ends of the shrinking spring 4 are respectively fixedly connected to the shrinking sleeve 3 and the shrinking rod 5, the end of the shrinking rod 5 away from the shrinking spring 4 is fixedly connected to the pipe sleeve 6, the outer wall of the drainage tube body 2 is slidably connected to the inner wall of the pipe sleeve 6, and the side of the adhesive plate 1 close to the drainage tube body 2 and away from the glue layer is connected to a reinforcement structure.

[0027] like Figure 1 - Figure 6As shown, the drainage tube with a fixed function in the utility model is similar to the existing drainage tube with a fixed function, such as the drainage tube with a fixed function disclosed in the patent with announcement number CN213526649U. The main improvement of the utility model is that the fixed structure on the drainage tube can be appropriately moved as needed to improve the applicability of the drainage tube, such as Figures 1 to 6 As shown, when the drainage tube with a fixing function in the utility model is in use, the contraction spring 4 pulls the contraction rod 5 and the tube sleeve 6 to move into the contraction sleeve 3. When the tube sleeve 6 is close to the contraction sleeve 3, the two ends of the drainage tube body 2 inserted in the tube sleeve 6 are against the outside of the contraction sleeve 3, so that the drainage tube body 2 is clamped between the tube sleeve 6 and the contraction sleeve 3 by the contraction force of the contraction spring 4, avoiding the drainage tube body 2 from sliding in the tube sleeve 6. When it is necessary to move the pasting plate 1, the tube sleeve 6 can be pulled toward the outside of the contraction sleeve 3, so that the drainage tube body 2 can be moved. The body 2 is separated from the shrinking sleeve 3. At this time, the adhesive plate 1 together with the entire tightening mechanism can be slid on the drainage tube body 2. When sliding to a suitable position, release the pull on the tube sleeve 6, and the shrinking spring 4 can drive the shrinking rod 5 and the tube sleeve 6 to move toward the shrinking sleeve 3, and the drainage tube body 2 is pressed against the outside of the shrinking sleeve 3 again to fix the drainage tube body 2, which is convenient for moving the adhesive plate 1 on the drainage tube body 2 when needed and fixing the drainage tube body 2 at a suitable position, further improving the applicability of fixing the drainage tube body 2.

[0028] like Figure 1 - Figure 4 As shown, a tube loosening opening 301 is provided on one side of the shrink sleeve 3 away from the pasting plate 1. When the drainage tube body 2 is loosened, the shrinking rod 5 can be slid toward the outside of the shrink sleeve 3 through the tube loosening opening 301, without directly pulling the tube sleeve 6, thereby avoiding damage to the drainage tube body 2 when pulling the tube sleeve 6.

[0029] like Figure 3 - Figure 6 As shown, the retractable rod 5 is fixedly connected with a push block 7 at one end close to the retractable spring 4 and away from the adhesive plate 1, and the push block 7 is slidably connected to the tube release opening 301. When the retractable rod 5 is pushed through the tube release opening 301, the tube sleeve 6 can be pushed away from the retractable sleeve 3 by pressing the push block 7 and pushing it in the direction of the tube sleeve 6, thereby releasing the restraint on the drainage tube body 2, and the operation is more convenient.

[0030] like Figure 4 - Figure 6 As shown, a side of the push block 7 away from the retracting rod 5 is provided with an anti-skid groove 701. By arranging the anti-skid groove 701 on the push block 7, it can be made more stable when the push block 7 is pushed, and it is not easy to slide.

[0031] like Figure 2 - Figure 6As shown, a tube clamping opening 601 is provided through the tube sleeve 6 on one side close to the retracting rod 5 and away from the pasting plate 1. By providing the tube clamping opening 601 on the tube sleeve 6, the tube sleeve 6 becomes hook-shaped, so that the drainage tube body 2 can be conveniently taken out of the tube sleeve 6 through the tube clamping opening 601, so that the pasting plate 1 and the tightening mechanism can be removed after the drainage tube body 2 is used, and connected with another drainage tube body 2, so that the pasting plate 1 can be recycled and the waste of materials can be reduced.

[0032] like Figure 1 - Figure 4 As shown, the reinforcement structure includes two U-shaped limiting sleeves 8, which are respectively located on both sides of the pipe sleeve 6 and connected to the adhesive plate 1 at the same time, and the inner walls of the two U-shaped limiting sleeves 8 are against the outer wall of the drainage tube body 2. After the drainage tube body 2 is fixed by the tightening mechanism, the two ends of the drainage tube body 2 located on the pipe sleeve 6 can be clamped in the U-shaped limiting sleeves 8 on both sides, and the two ends of the drainage tube body 2 are limited and fixed by the U-shaped limiting sleeves 8 on both sides, so as to further improve the fixing effect of the drainage tube body 2.

[0033] like Figure 1 - Figure 4 As shown, the inner walls of the two U-shaped limiting sleeves 8 are offset from the inner wall of the tube sleeve 6. By offsetting the inner side of the U-shaped limiting sleeve 8 from the inner wall of the tube sleeve 6, the two ends of the drainage tube body 2 can be clamped by the offset, so that the drainage tube body 2 is not easy to slide after being fixed.

[0034] like Figure 1 - Figure 4 As shown, one end of the two U-shaped limiting sleeves 8 is hinged to the pasting plate 1 through a hinge, and the ends of the two U-shaped limiting sleeves 8 away from the pasting plate 1 are connected to a U-shaped rod 9, and the two ends of the U-shaped rod 9 are respectively fixedly connected to the two U-shaped limiting sleeves 8. After the drainage tube body 2 is inserted into the tube sleeve 6, the contraction spring 4 drives the tube sleeve 6 to contract and clamps the drainage tube body 2 outside the contraction sleeve 3. At this time, the U-shaped rod 9 can be used to drive the U-shaped limiting sleeves 8 on both sides to flip downward through the hinge, and the two U-shaped limiting sleeves 8 are clamped on the outside of the drainage tube body 2 at both ends of the tube sleeve 6, thereby completing the re-fixation of the drainage tube body 2, and further improving the fixing effect of the drainage tube body 2.

[0035] like Figure 1 - Figure 4 As shown, a glue layer is provided on the side of the U-shaped rod 9 away from the U-shaped limiting sleeve 8. By providing the glue layer on the U-shaped rod 9, after the U-shaped rod 9 drives the two U-shaped limiting sleeves 8 to clamp the drainage tube body 2, the U-shaped rod 9 can be adhered to the patient's skin through the glue layer, and cooperate with the adhesive plate 1, so that the entire fixing structure is firmly fixed and adhered to the patient's skin, thereby improving the fixing effect of the drainage tube body 2.

[0036] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
