Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, and more specifically, it relates to a novel flushable integrated drainage tube structure. Background Technology
[0002] The current incision drainage tube is an integrated silicone tube connected to a negative pressure bulb. During abdominal surgery, the subcutaneous drainage tube is placed when the subcutaneous tissue layer is closed. After the abdomen is closed, the negative pressure bulb is squeezed to create negative pressure. The tube is removed 6 days after the operation.
[0003] Based on the above, the inventors have discovered the following problems: the negative pressure of the negative pressure drainage ball is weak and it has no flushing function. When the tube is removed, fibrous tissue strips can often be seen forming inside the lumen, which are easy to remain in the wound and cause secondary infection. Once the incision infection occurs, the wound needs to be opened for debridement and dressing, which increases the length of hospital stay and hospitalization costs.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a new type of washable integrated drainage tube structure in order to achieve a more practical purpose. Utility Model Content
[0005] The purpose of this disclosure is to address the technical problems in related technologies by providing a novel washable integrated drainage tube structure. The specific solution is as follows:
[0006] A novel flushable integrated drainage tube structure includes a flushing drainage tube, one end of which is provided with a negative pressure interface, and the other end of which is provided with a tube body opening; an inlet pipe is provided inside the flushing drainage tube, and an outlet is provided at one end of the inlet pipe near the tube body opening, and the other end of the inlet pipe penetrates through the side wall of the flushing drainage tube to form an inlet.
[0007] In some embodiments, the lumen at the negative pressure interface is shaped like a Laval nozzle.
[0008] In some embodiments, the sidewall of the flushing drainage tube is symmetrically provided with a plurality of first side holes.
[0009] In some embodiments, the plurality of first side holes are symmetrically arranged along both sides of the water inlet pipe.
[0010] In some embodiments, a sealing cap is also included, which is stitched to the flushing drainage tube.
[0011] In some embodiments, the sealing cap includes a pipe wall, and a through groove is formed on one side of the pipe wall.
[0012] In some embodiments, the sidewalls of the pipe are symmetrically provided with a plurality of second side holes, the second side holes being positioned corresponding to the first side holes.
[0013] In some embodiments, the plurality of second side holes are symmetrically arranged along both sides of the through groove.
[0014] In some embodiments, the sealing cap further includes a base disposed at one end of the pipe wall.
[0015] In some embodiments, the base has a third side hole.
[0016] Compared with the prior art, the present invention has at least one of the following beneficial effects:
[0017] This utility model discloses a flushable integrated drainage tube structure, comprising a flushing drainage tube. One end of the flushing drainage tube has a negative pressure interface, and the other end has a tube body opening. An inlet pipe is installed inside the flushing drainage tube, with an outlet at the end near the tube body opening, and the other end of the inlet pipe penetrating the side wall of the flushing drainage tube to form an inlet. By connecting to a wall-mounted negative pressure or negative pressure drainage device through the negative pressure interface, a greater negative pressure is achieved, resulting in better removal of accumulated fluid. Simultaneously, the flushing function is enhanced, reducing tube blockage and improving the negative pressure effect, effectively preventing and reducing postoperative incision infection, lowering the postoperative incision infection rate, reducing patient hospital stay, reducing hospitalization costs, and increasing patient comfort.

[0033] The optional embodiments of this disclosure are described in detail below with reference to the accompanying drawings.
[0034] As attached Figure 1 To be continued Figure 6 As shown, this utility model provides a flushable drainage tube structure, including a flushing drainage tube 1 and a sealing cap 8. One end of the flushing drainage tube 1 is provided with a negative pressure interface 2, and the other end of the flushing drainage tube 1 is provided with a tube body opening 5. A water inlet pipe 3 is installed inside the flushing drainage tube 1. One end of the water inlet pipe 3 penetrates the tube wall of the flushing drainage tube 1 to the outside to form a water inlet 4. The end of the water inlet pipe 3 located at the tube body opening 5 is provided with a water outlet 6. Through the design of the negative pressure interface 2, a wall negative pressure or bellows-type negative pressure drainage device can be connected at the negative pressure interface 2, which has a good effect on clearing accumulated liquid.
[0035] The negative pressure interface 2 has a tube shape resembling a Laval nozzle. This design increases the outflow speed of the drainage fluid and makes it less likely to form cellulose deposits.
[0036] The flushing and drainage pipe 1 has several first side holes 7 symmetrically formed on its surface. The several first side holes 7 are symmetrically arranged along both sides of the water inlet pipe 3.
[0037] The sealing cap 8 includes a pipe wall 9 and a base 10, with the base 10 disposed at one end of the pipe wall 9. A through groove 11 is provided on one side of the pipe wall 9. The design of the through groove 11 allows the central pipe wall 9 to avoid the protrusion of the outlet 6, facilitating its use.
[0038] The pipe wall 9 has a plurality of second side holes 12 symmetrically opened on its sidewalls. The plurality of second side holes 12 are symmetrically arranged along both sides of the through groove 11, and the positions of the second side holes 12 and the first side holes 7 are corresponding. The second side holes 12 and the first side holes 7 are used together to facilitate the stitching and fixing of the sealing cap 8 and the flushing drainage pipe 1 together.
[0039] The base 10 has a third side hole 13. The base 10 serves as a seal to prevent tissue from being drawn into the flushing and drainage tube 1, thus reducing secondary damage.
[0040] First, check the integrity of the device. It can only be used after confirming that there are no problems. Before closing the subcutaneous tissue during surgery, cut the irrigation drainage tube 1 according to the incision length, and then install the sealing cap 8. The tube wall 9 of the sealing cap 8 extends into the irrigation drainage tube 1. Then, use the first side hole 7 and the second side hole 12 of the irrigation drainage tube 1 and the sealing cap 8 to suture and fix them together. When placing it, the water inlet tube 3 is on top. Place it under the skin and suture the skin intermittently. After returning to the ward, connect the negative pressure interface 2 to the wall negative pressure or accordion-type negative pressure drainage device, and connect the water inlet 4 to the normal saline for drip infusion. The lumen of the negative pressure interface 2 adopts the Laval spray tube design, which accelerates the outflow of drainage fluid and makes it less likely to form fibrous deposits. Remove the irrigation drainage tube 1 about 6 days after surgery. If the wound is long, it can be removed and replaced with another shorter irrigation drainage tube 1 for a transition period of 3 days before removal.
[0041] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the systems or apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the descriptions are relatively simple, and relevant parts can be referred to the method section.
