Description

Technical Field

[0001] The present invention relates to the technical field of medical supplies, and particularly to an anti-permeation drainage tube for clinical use in oncology departments. Background Art

[0002] There are many types of surgical drainage tubes used clinically. Some are used for urinary catheterization, and some are used for wounds, gastrointestinal tracts, biliary tracts, etc. Surgical drainage is to guide pus, blood, and fluid accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection and affect wound healing.

[0003] After retrieval, the authorized announcement number CN214860358U discloses an anti-permeation drainage tube for clinical use in oncology departments, which mainly consists of a drainage head (1), an anti-leakage patch (2), a drainage tube (3), a connector (4), a drainage bottle (5), and a negative pressure device (6). The drainage head (1), the anti-leakage patch (2), the drainage tube (3), and the connector (4) are connected in sequence from left to right. The drainage bottle (5) and the negative pressure device (6) are both detachably connected to the connector (4). In the above solution, the anti-permeation drainage tube for clinical use in oncology departments has a simple structure, low cost, and is easy to use. The device can effectively prevent the accumulated fluid from permeating and flowing out during the drainage process through the anti-leakage patch, and the drainage head can be pulled out through the mounting seat without uncovering the anti-leakage patch, preventing the residual accumulated fluid from leaking out and polluting the outside when the drainage tube is removed.

[0004] In the above technical solution: the anti-leakage patch is set to prevent the accumulated fluid from flowing out. However, in actual use, since the anti-leakage patch is pasted on the patient's skin, the accumulated fluid will slowly penetrate into the contact layer between the anti-leakage patch and the patient's skin. Over time, the viscosity of the anti-leakage patch decreases, and at this time, the anti-leakage patch is easily detached. The detached anti-leakage patch drives the drainage tube to shift, and at this time, it is easier to dirty clothes, bedding, etc.

[0005] Therefore, we propose an anti-permeation drainage tube for clinical use in oncology departments. Summary of the Invention

[0006] The present invention mainly solves the above technical problems and provides an anti-permeation drainage tube for clinical use in oncology departments.

[0007] To achieve the above object, the present invention adopts the following technical solution. An anti-permeation drainage tube for clinical use in oncology departments includes a sticking film, an anti-permeation ring, and a collection bottle. A through hole is formed through the sticking film. During use, the sticking film is pasted on the patient's skin, and the drainage openings on the patient's body are distributed at the positions of the through holes.

[0008] The outer side of the anti-permeation ring is provided with a rubber connection shell. An inner plate is fixedly installed inside the anti-permeation ring through a connection ear. An annular cavity is formed between the outer side of the inner plate and the inner side of the anti-permeation ring. A drainage tube is fixedly installed at the center of the inner plate. During use, the adhesive film is pasted at the position of the drainage opening on the patient's body. The adhesive pad drives the anti-permeation ring to be pasted and fixed on the outer surface of the adhesive film. At this time, the drainage tube passes through the drainage opening and extends inward, and the liquid in the drainage opening is drained outward through the drainage tube.

[0009] The outer surface of the anti-permeation ring is respectively fixedly installed with a first protective shell and a second protective shell. Two groups of support plates are fixedly installed inside both the first protective shell and the second protective shell. A first winding shaft is rotatably installed between the two groups of support plates in the second protective shell. A second winding shaft is rotatably installed between the two groups of support plates in the first protective shell. A compressed cotton strip is wound on the first winding shaft, and the free end of the compressed cotton strip passes through the annular cavity and is wound on the second winding shaft.

[0010] Preferably, a paste pad is fixedly sleeved on the outer circle of the anti-permeation ring. The inner side of the paste pad is provided with an adhesive layer. The anti-permeation ring is fixedly pasted on the adhesive film through the paste pad.

[0011] Preferably, a control handle is rotatably installed on the outer side of the first protective shell. The control handle is fixedly connected to the second winding shaft through a rotating shaft.

[0012] Preferably, a first docking head is fixedly installed on the outer surface of the rubber connection shell. The outer end of the drainage tube is fixedly connected to the first docking head and is in communication with each other.

[0013] Preferably, the collection bottle is provided with a bottle body connection part, and a hose is fixedly installed on the bottle body connection part.

[0014] Preferably, the free end of the hose is detachably connected to the first docking head through a second docking head.

[0015] Preferably, a negative pressure device is provided on the collection bottle.

[0016] Preferably, the anti-permeation ring is made of a transparent material, and the inner plate and the anti-permeation ring are coaxially arranged.

[0017] Beneficial effects

[0018] The present invention provides an anti-permeation drainage tube for oncology clinical use. It has the following beneficial effects:

[0019] (1) The anti-seepage drainage tube for clinical use in oncology department, when in use, the adhesive film is pasted on the patient's skin. The drainage openings on the patient's body are distributed at the positions of the through openings. The anti-seepage ring is fixedly pasted on the adhesive film through the adhesive pad. At this time, the drainage tube passes through the drainage opening and extends inward, and the accumulated liquid in the drainage opening is drained outward through the drainage tube. The large-area adhesive film drives the anti-seepage ring to be fixed on the patient's body, achieving the effect of improving the firmness of the anti-seepage ring pasting.

[0020] (2) The anti-seepage drainage tube for clinical use in oncology department, when in use, the adhesive film is pasted on the patient's skin. The drainage openings on the patient's body are distributed at the positions of the through openings. The anti-seepage ring is fixedly pasted on the adhesive film through the adhesive pad. At this time, the drainage tube passes through the drainage opening and extends inward, and the accumulated liquid in the drainage opening is drained outward through the drainage tube. The compressed cotton strips distributed in the annular cavity will be attached to the patient's skin, and the compressed cotton strips distributed in the annular cavity adsorb the overflowing accumulated liquid at the drainage opening to avoid the outward seepage of the accumulated liquid. Since the anti-seepage ring is made of a transparent material, when the compressed cotton strips distributed in the annular cavity adsorb contaminated accumulated liquid, people control the control handle to rotate, so that the control handle winds up the contaminated compressed cotton strips, thereby ensuring that the compressed cotton strips in the annular cavity can continuously adsorb the accumulated liquid, controlling the outward seepage of the accumulated liquid at the drainage opening, thereby ensuring that the adhesive film is closely pasted on the patient's body, and at the same time ensuring that the anti-seepage ring is closely pasted on the outer surface of the adhesive film, achieving the effect of timely adsorbing the overflowing accumulated liquid and efficiently avoiding the outward seepage of the accumulated liquid.

[0060] The working principle of the present invention:

[0061] In use, the adhesive film 1 is adhered to the patient's skin. The drainage openings on the patient's body are distributed at the positions of the through openings 2. The anti-permeation ring 3 is adhesively fixed to the adhesive film 1 through the adhesive pad 4. At this time, the drainage tube 6 extends inward through the drainage opening, and the accumulated liquid in the drainage opening is drained outward through the drainage tube 6. The compressed cotton strips 12 distributed in the annular cavity will be attached to the patient's skin, and the accumulated liquid overflowing from the drainage opening is adsorbed by the compressed cotton strips 12 distributed in the annular cavity to prevent the accumulated liquid from permeating outward. Since the anti-permeation ring 3 is made of a transparent material, when the compressed cotton strips 12 distributed in the annular cavity are contaminated by adsorbed accumulated liquid, people control the control handle 13 to rotate, so that the control handle 13 winds up the contaminated compressed cotton strips 12, thereby ensuring that the compressed cotton strips 12 in the annular cavity can continuously adsorb the accumulated liquid, controlling the outward permeation of the accumulated liquid at the drainage opening, thereby ensuring that the adhesive film 1 is closely adhered to the patient's body, and at the same time ensuring that the anti-permeation ring 3 is closely adhered to the outer surface of the adhesive film 1.

[0062] A negative pressure device 16 provides negative pressure so that the accumulated liquid is sequentially extracted through the drainage tube 6 and the hose 17 and collected inside the collection bottle 14.

[0063] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
