[0002] A trocar is a medical and laboratory tool used primarily for venipuncture, blood drawing, drug injection or infusion. It consists of a hollow needle and an outer cannula. The needle is usually sharp and is used to penetrate the skin, while the cannula can remain in the body after the needle is removed for drug delivery or blood collection. After venipuncture, a transparent dressing or other type of dressing is usually applied to fix the puncture site, prevent infection and protect the wound. Trocars can reduce damage to blood vessels and reduce discomfort after puncture. They can also continue infusion or other operations after the needle is removed, which improves the convenience of operation. In addition, it avoids the need for multiple punctures and reduces the patient's pain.

[0003] However, the conventional patch used in the prior art is a whole piece attached to the trocar, and the needle stem of the trocar is placed under the patch, which can easily reduce the stickiness of the patch and the patient can easily touch the puncture site during activities, causing discomfort to the patient.

[0031] This embodiment provides an application assembly that is not easy to curl and prevents redness. Figures 1 to 3 As shown, it includes an application body and an additional part. A visual window 2 is provided in the center of the application body. A transparent polyurethane film is provided on the visual window 2 for observing the needle insertion point so as to promptly detect bleeding, redness, infection, or even tube detachment at the needle insertion point.

[0032] The dressing body includes an adhesive layer 1 and a dressing layer 3, which are stacked in sequence. A first sponge pad 5 is provided at the edge of the adhesive layer 1, and the first sponge pad 5 is used to pad under the stem of the trocar to prevent the stem from pressing the skin for a long time; the adhesive layer 1 is also provided with a tearable fixing belt 4, and the tearable fixing belt 4 is used to fix the trocar 6. The adhesive layer 1 is provided with a plurality of small holes, and the small holes are located directly below the dressing layer 3, so that the silver ion dressing in the dressing layer can penetrate and play an anti-inflammatory role. The dressing layer 3 is filled with silver ion dressing for anti-inflammatory; the silver ion dressing adopts the Miaotie silver-containing wound dressing produced by German Bauhemann AG.

[0033] The first sponge pad 5 is triangular in shape, with the long side of the first sponge pad 5 flush with the edge of the adhesive layer 1, one short side of the first sponge pad 5 is an integrated structure with the adhesive layer 1, and the other short side of the first sponge pad 5 is a separate structure from the adhesive layer 1. One end of the tearable fixing belt 4 is fixedly connected to the adhesive layer 1, and the other end is tearable. Two tearable fixing belts 4 are provided, and the two tearable fixing belts 4 are respectively located on both sides of the trocar 6, and are used to cross-fix the needle stem of the trocar 6.

[0034] The attachment is used to fix the extended end of the trocar, and includes a base 10, a sealing cover 7, a support 8, and a second sponge pad 9. The second sponge pad 9 and the support 8 are fixed on the base 10. The sealing cover 7 is clamped with the support 8, and the support 8 is fixed on both sides of the second sponge pad 9. A groove is provided on the second sponge pad 9, and the groove is used to place the extended end of the trocar. The base 10 is irregular in shape, and the bottom layer of the base 10 is sticky, which is used to stick the attachment to the skin.

[0035] A third sponge pad is disposed on the inner side of the sealing cover 7 , and the third sponge pad cooperates with the second sponge pad 9 to fix the extended end of the trocar. The sealing cover 7 is made of silicone material.

[0036] like Figure 1 As shown, when the trocar 6 is puncturing, the visual window 2 is aligned with the puncture site and the dressing body is adhered to the skin, and then the first sponge pad 5 is flipped from the top of the trocar 6 to the bottom of the trocar 6 to prevent the needle tube from pressing the skin for a long time. After tearing the tearable fixing tape 4 in the opposite direction of the arrow, the tearable fixing tape 4 is wrapped around the bottom side of the trocar 6, and the final fixing direction is the direction of the arrow of the tearable fixing tape 4 to fix the trocar needle stem. When the trocar 6 does not have an extension end, the dressing body is used for fixing; when the trocar 6 has an extension end, the dressing body and the attachment are used to fix the trocar 6 and its extension end to avoid poor fixation of the extension end resulting in the tube coming off and crushing the skin.
