DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example 1: Please refer to Figure 1 - Figure 4 The illustrated device is a fixing device for puncture and drainage tube in thoracic and cardiovascular surgery, comprising a fixing seat 1, a strap 2 is fixed to the outside of the fixing seat 1, a Velcro is fixed to the outer end of the strap 2, a receiving groove 3 is provided in the fixing seat 1, swing-in grooves 4 for inserting the drainage tube are provided at both ends of the fixing seat 1, a protrusion 5 is fixed to the outside of one end of the drainage tube and abuts against one of the swing-in grooves 4; and a fitting sheet 6, the fitting sheet 6 is fitted with the drainage tube, a buffer unit 7 abutting against the fitting sheet 6 is installed in the receiving groove 3, the fitting sheet 6 is pushed to fit the drainage tube through the buffer unit 7, and the drainage tube is buffered and stored; and a locking unit 8 connected to the fitting sheet 6, the locking unit 8 is used to press the drainage tube tightly to lock the drainage;

[0029] In this solution, the drainage tube is swung into the storage groove 3, and the drainage tube is stored in the storage groove 3 in a bent state through the bonding sheet 6. The buffer unit 7 can provide a certain degree of buffering when the drainage tube is accidentally pulled, thereby effectively avoiding the drainage tube from being separated from the affected area due to pulling. At the same time, the designed locking unit 8 can quickly squeeze and deflate the drainage tube to stop drainage and avoid backflow.

[0030] For further information, see Figure 2 - Figure 6 The buffer unit 7 includes an adjusting column 9 and an adjusting wheel 10. The adjusting wheel 10 is rotatably mounted on the fixing seat 1 and is threadedly connected to the adjusting column 9. An abutting ring 11 is fixed to one end of the adjusting column 9 and the outer side of the fitting sheet 6. A buffer spring 12 is fixed between the two abutting rings 11. A limiting groove 13 is provided on the outer side of the adjusting column 9. A limiting ring 14 is fixed in the fixing seat 1 and is slidably docked with the limiting groove 13.

[0031] It should be noted that when the outer end of the drainage tube is accidentally pulled, the drainage tube of the receiving groove 3 will be pulled to straighten the bent state, so that the bonding sheet 6 retreats, driving the buffer spring 12 to retract. The retraction range of the buffer spring 12 satisfies the pulling of the drainage tube within a certain range. After the pulling is completed, the drainage tube is returned to the bent state by the buffer spring 12.

[0032] When the patient is in different states, such as lying in bed or getting out of bed, the drainage tube will be pulled in different states. The staff can turn the adjusting wheel 10 to make the adjusting column 9 move accordingly, thereby controlling the distance between the two abutting rings 11 to adjust the retraction distance of the buffer spring 12, so as to control the pulling amplitude of the drainage tube accordingly, which is suitable for pulling the drainage tube in different states.

[0033] For further information, see Figure 2 , Figure 4 as well as Figure 7 and Figure 8 The locking unit 8 includes a locking rod 15 slidably plugged with the adjusting column 9, one end of the locking rod 15 is slidably plugged with the fitting sheet 6 and fixed with a locking member 16, and the other end of the locking rod 15 is installed with an adjusting assembly 17;

[0034] The adjusting assembly 17 includes an adjusting tube 18 installed and fixed on the outside, a moving groove 19 is opened on the adjusting tube 18, locking grooves 20 are opened at both ends of the moving groove 19, an adjusting ring 21 is rotatably installed at the tail end of the locking rod 15, and an adjusting block 22 is fixed on the adjusting ring 21 to slide and dock with the moving groove 19;

[0035] It is worth noting that, in order to facilitate the adjustment of the adjustment block 22, an adjustment plate 23 is fixed on the outside of the adjustment block 22, and anti-slip grooves are provided on the outside of the adjustment plate 23. The area of ​​the adjustment plate 23 is larger, and it is more convenient for personnel to adjust.

[0036] The locking member 16 includes an abutting piece 24 fixed to the outside of the locking rod 15 , and a blocking piece 25 is fixed to the top of the fitting sheet 6 at a position corresponding to the abutting piece 24 .

[0037] In this solution, the locking unit 8 is used to collapse the drainage tube to stop drainage and avoid backflow.

[0038] First, when drainage is not needed or when personnel accidentally discover backflow, personnel directly push the adjustment plate 23, so that the adjustment block 22 moves toward the receiving groove 3 in the moving groove 19, driving the adjustment ring 21 and the locking rod 15 to move, and then rotates after moving to one end of the moving groove 19, so that the adjustment block 22 docks with the locking groove 20. When the locking rod 15 moves, it drives the abutting piece 24 to squeeze the drainage tube, and under the action of the baffle 25, the drainage tube is compressed, thereby achieving the effect of stopping drainage and preventing backflow;

[0039] When placing the drainage tube, the personnel can drive the adjustment block 22 to move away from the storage slot 3, and then rotate it after moving to one end of the movable slot 19, so that the adjustment block 22 is docked with the locking slot 20. At this time, the bonding sheet 6 is pulled backwards, and after the personnel puts the drainage tube in, they can make good use of the bonding sheet 6 to offset and store the drainage tube.

[0040] It should be noted that in order to prevent the counter-piece 24 from being too protruding in the fitting piece 6 and affecting the sliding of the drainage tube, a groove 26 is provided on the fitting piece 6 at the position corresponding to the counter-piece 24. At the same time, the cross-sectional shape of the fitting piece 6 is L-shaped, so that when the drainage tube is squeezed, the baffle 25 can be used to limit the drainage tube well, thereby achieving a better extrusion effect.

[0041] Example 2: Please refer to Figure 1 and Figure 2 This embodiment further explains the first embodiment, and the difference lies in that a cover plate 28 is added to provide certain protection for the drainage pipe in the storage tank 3.

[0042] Specifically, a gasket 27 is fixed in the storage groove 3, and a cover plate 28 is provided on the fixing seat 1. The cover plate 28 and the gasket 27 are magnetically attracted to each other, wherein a notch 29 is provided on the cover plate 28 at a position corresponding to the adjusting wheel 10, so that personnel can directly adjust the adjusting wheel 10, and the cover plate 28 is made of a transparent material;

[0043] In this solution, the cover 28 is connected to the gasket 27 by magnetic attraction, so that it can be well installed on the storage slot 3. At the same time, the transparent material allows personnel to intuitively observe the state of the internal drainage tube. When the buffer amplitude needs to be adjusted, it can also be adjusted directly through the adjustment wheel 10 at the recess 29. When opening the cover 28, it can also be assisted by the recess 29.

[0044] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
