Description

Technical Field

[0001] The invention relates to a bathing protective cover after percutaneous catheterization. Background Art

[0002] Clinically, there are a large number of patients with abscesses, hematomas, cysts, serous cavity effusions (including pleural cavity, peritoneal cavity, pericardial cavity, joint cavity), bile duct or urinary tract obstruction in various parts of the body. For treatment needs, these patients need percutaneous puncture and indwelling drainage tubes, which are retained for a period of time, and some are even retained for several years. The drainage tube is about 1.5 to 2 meters long, with a drainage bag connected to the end. The inside of the tube is a sterile environment and cannot be disassembled frequently. The puncture site must be kept dry as much as possible, otherwise it is easy to cause infection. These restrictions make bathing very inconvenient for patients and seriously affect their quality of life.

[0003] There is a kind of drainage tube waterproof film, which is a disposable product and is mainly used for patients after gastrostomy and peritoneal dialysis catheterization. Such patients do not need external drainage bags and do not need aseptic protection. The waterproof film is thin and flat, suitable for relatively flat puncture sites, but not for drainage tubes with external drainage bags; the product is sticky, and if it is accidentally stuck to the drainage tube, it is easy to pull off the tube when peeling it off; the product is a disposable consumable and is expensive.

[0004] In summary, there is a lack of effective and convenient products on the market for such patients to protect them during bathing. Existing protective measures cannot simultaneously meet multiple requirements such as waterproofness, bag sealing, easy putting on and taking off, reusability, and adaptability to different body parts and drainage tube lengths. Therefore, it is necessary to develop a new type of bathing protective cover. Summary of the invention

[0005] In order to solve the problems existing in the above-mentioned background technology, the present invention proposes a bathing protective cover after percutaneous catheterization, which is a waterproof device used to protect the puncture site, drainage tube and drainage bag of patients after percutaneous catheterization when bathing. It has the advantages of space for placing drainage tube and drainage bag, reusability and easy putting on and taking off.

[0006] The technical solution of the present invention to solve the above problem is: a bathing protective cover after percutaneous catheterization, which is special in that:

[0007] Includes storage bag and tie-down kit;

[0008] The bag opening of the storage bag is provided with a fitting portion, which is a ring-shaped structure. The side of the fitting portion away from the storage bag is a fitting surface, and a sealing structure is provided on the fitting surface. The binding assembly includes an adjustment belt and an adjustment buckle. Two adjustment belts are symmetrically arranged on a side of the fitting portion close to the storage bag, and the length of the adjustment belt is adjusted by the adjustment buckle.

[0009] Furthermore, the edge of the bag opening of the above-mentioned storage bag is connected to the inner edge of the fitting part; the binding assembly also includes two fixing ears, which are symmetrically arranged on a side of the fitting part close to the storage bag, and the adjustment belt is connected to the fixing ears.

[0010] Furthermore, the sealing structure comprises a first sealing structure and a second sealing structure, wherein the first sealing structure is located at an outer edge of the bonding surface of the bonding portion; and the second sealing structure is located at an inner edge of the bonding surface of the bonding portion.

[0011] Furthermore, a plastic annular metal ring is embedded inside the above-mentioned fitting portion, and the plastic annular metal ring is used to fix the shape of the disc and apply pressure.

[0012] Furthermore, the first sealing structure is an annular protrusion, and the annular protrusion gradually becomes thinner from the bottom to the top.

[0013] Furthermore, the second sealing structure is also an annular protrusion, and its width is greater than that of the first sealing structure.

[0014] Furthermore, the outer contour of the cross section of the top of the second sealing structure is in the shape of an arc, a rectangle or a trapezoid.

[0015] Furthermore, the position of the annular metal ring corresponds to the position of the second sealing structure.

[0016] Furthermore, the storage bag is made of silica gel and PVC materials mixed in a certain proportion, and is made into the basic shape of the storage bag through an injection molding process to ensure that it has a suitable thickness and strength, and can withstand a certain amount of external force and wear in daily use while ensuring waterproof performance.

[0017] Furthermore, the above-mentioned fitting part is mainly made of silicone, which has good micro-adhesion and flexibility. During the production process, it is tightly combined with the protective cover body through a molding process to ensure that the sealing performance of the bag opening is stable and reliable.

[0018] Furthermore, the adjustment belt may be an elastic belt. When in use, the patient's breathing or other movements may cause the skin to contract, and the elastic belt always has contraction force to ensure that it will not loosen during use.

[0019] Furthermore, the above-mentioned adjustment belt is made of silicone belt, and the adjustment buckle is made of plastic material, which ensures that the adjustment buckle has a compact structure and smooth operation, can accurately adjust the length of the long belt, and will not loosen or be damaged during long-term use.

[0020] Advantages of the present invention:

[0021] ①Good waterproof performance

[0022] The storage bag in the present invention is made of a composite material of silica gel and PVC. Silica gel itself has excellent waterproof performance, which can effectively prevent moisture from entering the protective cover, avoid the puncture site and the drainage device from getting wet, reduce the risk of infection for patients during bathing, and provide a safe environment for patients' postoperative recovery.

[0023] ②The bag mouth is sealed reliably

[0024] The fitting part at the bag opening of the present invention is soft and sticky, which can fit the skin tightly without causing damage to the skin. While ensuring a good sealing effect, it can be easily peeled off after use without any glue stains remaining. It can still maintain reliable micro-stickiness after repeated use, effectively preventing moisture from penetrating from the bag opening.

[0025] ③Easy to put on and take off

[0026] The bag-shaped design of the present invention allows the patient to simply put the protective cover on the puncture port, the drainage tube and the drainage bag, and then fit the bag opening to the skin, which is simple and convenient to operate. After bathing, it is also very easy to remove the protective cover, which will not cause too much trouble and discomfort to the patient.

[0027] ④Reusable

[0028] The storage bag of the present invention is mainly made of silica gel and PVC, which have good durability and can be reused many times, thereby reducing the use cost of the patient and also reducing the waste of medical resources.

[0029] ⑤Stable and comfortable to wear

[0030] The adjustable length adjustment belt of the present invention can be flexibly adjusted according to the patient's body size and wearing position requirements, so that the protective cover can be firmly tied to the patient's body to ensure that it will not shift or fall off during the bathing process, providing stable protection for the patient. In addition, the adjustment belt is made of elastic material and has a certain degree of softness, which will not cause excessive restraint to the patient's body and is more comfortable to wear.

[0031] ⑥Wide scope of application

[0032] The protective cover can simultaneously place the puncture port, drainage tube and drainage bag of the fistula patient therein, and is suitable for patients who need bathing protection after various percutaneous puncture and catheterization operations, meeting the actual needs of different patients and having high versatility and practicality.
