Description

Technical Field

[0001] The utility model relates to the field of medical facilities, in particular to a butterfly-wing needle cap-shaped waterproof dressing. Background Art

[0002] With the aging of the population and changes in lifestyle, the incidence of malignant tumors in the population has increased year by year. Malignant tumors are mainly treated with a combination of treatments including surgery, chemotherapy, radiotherapy, and immunotherapy and biological therapy. Among them, chemotherapy plays an important role in controlling tumors and reducing postoperative recurrence, metastasis, and implantation opportunities. Chemotherapy is usually a long-term process. Currently, in clinical practice, patients need to undergo intravenous port implantation to ensure a safe and reliable intravenous infusion route. Generally, the intravenous port is implanted in the patient's anterior chest wall.

[0003] On the other hand, in the control of pain in advanced tumors, when conventional oral drugs cannot effectively relieve pain, non-gastrointestinal opioids are often used clinically, such as intrathecal administration. At this time, it is necessary to implant an infusion port in the patient's abdomen to connect the intrathecal catheter to the subarachnoid space to achieve long-term intrathecal analgesia.

[0004] The implementation of the above two solutions requires the use of a butterfly wing needle to puncture the injection seat of the infusion port and connect the infusion bottle. Due to the special structure of the butterfly wing needle, there is currently no special fixing dressing for the butterfly wing needle of the infusion port. Therefore, when fixing the butterfly wing needle, a surgical incision dressing is usually used instead to fix it, and at this time, a piece of open gauze needs to be placed under the needle wing to reduce the friction between the needle body and the skin around the infusion port, and at the same time avoid damage to the skin caused by the needle wing. After the patient has the butterfly wing needle indwelling, directly cover the incision dressing, and then use tape to fix the butterfly wing needle extension tube around the skin above the injection seat of the intravenous infusion port to prevent the butterfly wing needle from falling off.

[0005] In the process of using dressing to fix butterfly wing needles, there are the following disadvantages:

[0006] 1. When using dressings to fix butterfly wing needles, open gauze needs to be placed under the needle wing. At this time, the gauze is often stuck to the dressing tape covering it, which is difficult to remove when changing it, and may even pull out the butterfly wing needle;

[0007] 2. Due to the special shape of the butterfly needle, the surgical patch cannot fit completely when applied.

[0008] It is easy to curl up and not fit firmly, and it is easy to fall off. Frequent replacement will also cause waste of medical resources and increase the economic burden on patients;

[0009] 3. When changing the dressing, the butterfly needle may be too tightly attached to the dressing and difficult to remove. Improper force may pull out the butterfly needle together, and the butterfly needle may rebound and even cause skin punctures on the patient.

[0010] 4. Ordinary surgical dressings are made of non-waterproof materials and are easily soaked by water, causing infection or even ulceration at the puncture site. Therefore, after the butterfly wing needle is placed, the body cannot be cleaned or wiped, especially the intrathecal analgesic infusion port during cancer analgesia, which needs to be placed for life. Not being able to take a bath is very inconvenient for patients and seriously affects their social activities. Utility Model Content

[0011] In view of this, the purpose of the utility model is to provide a butterfly-wing needle cap-shaped waterproof dressing which is easy to use, easy to operate, safe and reliable, and has a good waterproof effect.

[0027] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0028] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0029] like Figures 1 to 4As shown, a butterfly wing needle cap-shaped waterproof dressing includes a water-absorbing sponge pad 1 and a cap-shaped dressing cover 2. The water-absorbing sponge pad 1 is arranged inside the dressing cover, but is not connected to the dressing cover, and the two are independent; a butterfly wing needle accommodating cavity 3 is formed inside the dressing cover 2, and the dressing cover is provided with a brim portion 4 at the outer periphery of the opening, and the lower side of the brim portion and the bottom surface of the water-absorbing sponge pad are both provided with a rubber coating layer, and a waterproof film 5 is attached to the upper surface of the dressing cover, and a needle hole 6 is opened in the middle of the water-absorbing sponge pad. The water-absorbing sponge pad 1 is disc-shaped, and its diameter is equivalent to the diameter of the butterfly wing needle commonly used in the market after extension. When in use, the dressing cover 2 covers the butterfly wing needle, and the water-absorbing sponge pad 1 is sandwiched between the butterfly wing needle and the skin. The absorbent sponge pad 1 can be attached to the skin surface to prevent displacement, and the adhesive layer is covered with release paper for protection. When in use, peel off the release paper and insert the absorbent sponge pad 1 between the butterfly needle and the skin. The absorbent sponge pad 1 can absorb a small amount of liquid exuded from the puncture point, and at the same time isolate the butterfly needle from the skin to prevent the butterfly needle from causing direct pressure and abrasion on the skin. The dressing cover 2 is formed in one piece with medical dressings. The materials of medical dressings generally include: polymer film dressings, foaming polymer dressings, hydrocolloid dressings, alginate dressings, etc. The product can be made of different materials as needed; the brim can be attached and fixed to the skin surface, and the adhesive layer on the lower side of the brim is protected by release paper. The release paper is peeled off when in use.

[0030] In this embodiment, the edge of the waterproof film extends from the brim of the application cover, and a rubber layer is provided on the bottom surface of the edge of the waterproof film. The application cover 2 is entirely covered with a waterproof film, and the rubber layer on the bottom surface of the edge of the waterproof film is protected by release paper, which is removed when in use.

[0031] In this embodiment, the top of the butterfly wing needle accommodating cavity is provided with a water-absorbing sponge block 7. The water-absorbing sponge block 7 is in close contact with the butterfly wing needle, and the butterfly wing needle can be fixed by the plastic deformation of the water-absorbing sponge block, which is not easy to move, and can also absorb a small amount of exudate.

[0032] In this embodiment, the water-absorbing sponge pad is provided with a groove 8 extending outward from the needle hole and penetrating the edge. The water-absorbing sponge pad is placed between the butterfly wing needle and the skin, and the needle body of the butterfly wing needle is inserted into the needle hole in the middle of the water-absorbing sponge pad through the groove.

[0033] When using, first place the absorbent sponge pad between the butterfly needle and the skin; tear off the release paper on the bottom of the brim, and cover the entire patch cover on the butterfly needle. The butterfly needle is in close contact with the absorbent sponge block on the top of the patch cover, and the butterfly needle can be fixed with the help of the plastic deformation of the absorbent sponge block, making it difficult to move; the brim is applied to the skin surface to fix the entire patch cover; then tear off the release paper of the adhesive layer on the waterproof film, compact the edge of the waterproof film and apply it to the skin to achieve the overall waterproof function of the patch. The infusion tube of the butterfly needle is led out from a low position after the patch cover and the waterproof film are tightly attached to the skin. Hence, the above-mentioned disadvantages can be effectively avoided, namely: (1) The disc-shaped absorbent sponge pad effectively isolates the direct contact between the butterfly wing needle and the skin, avoiding mechanical wear. At the same time, the absorbent sponge pad itself is fixed to the skin surface and is not easy to shift or fall off. In addition, it does not come into direct contact with the external dressing, making it easy to replace. (2) The dressing cover has a special structure that allows the absorbent sponge block on the top to deform and completely fit the butterfly wing needle, so it can fix the butterfly wing needle well, but it does not adhere to the butterfly wing needle. When replacing it, there is no risk of pulling out the butterfly wing needle, thus avoiding potential damage. (3) The dressing cover is equipped with a waterproof film to isolate the butterfly wing needle from contact with the outside world. When lightly wiped and rinsed, it is not easy to soak the internal puncture wound, effectively avoiding wound infection and potential catheter-related infection. Patients can clean and bathe freely without interfering with their daily lives, thus enhancing social interaction.
