[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0023] Example: Figure 1 and 2As shown, the trocar protective patch of this embodiment includes a main fixing patch 1, a first sub-patch 11 is provided on one side of one end of the above-mentioned main fixing patch 1, the above-mentioned first sub-patch 11 extends to the middle part of one end of the above-mentioned main fixing patch 1, and a needle handle pad 12 is provided on one side of the above-mentioned first sub-patch 11 corresponding to the middle part of one side of the above-mentioned main fixing patch 1, and a second sub-patch 13 is provided on the other side of one end of the above-mentioned main fixing patch 1, the above-mentioned second sub-patch 13 extends to one side end of one end of the above-mentioned main fixing patch 1 and is partially overlapped on one side of the above-mentioned first sub-patch 11, the surface of the above-mentioned needle handle pad 12 is covered with a first sterile release film, and the other surfaces of the above-mentioned main fixing patch 1, the first sub-patch 11 and the second sub-patch 13 are all provided with an adhesive layer, and the surfaces of the above-mentioned adhesive layers are respectively covered with a second sterile release film.
[0024] The usage process is as follows:
[0025] Taking the trocar insertion on the instep as an example, after the trocar is inserted (the needle head is shown in part b in the figure), tear off the second sterile release film on the other side of the main fixing patch 1, and stick the main fixing patch 1 on the outer surface of the skin corresponding to the blood vessel entered by the trocar, with the needle hole just facing the needle handle pad 12. Next, stick the first sub-patch 11 on the outer surface of the skin relative to one end of the main fixing patch 1 through the needle eye (that is, make the first sub-patch 11 pass through the gap between the trocar handle and the skin). After sticking, the needle eye is located between the first sub-patch 11 and the middle part of one end of the main fixing patch 1, and the needle handle pad 12 is just cushioned between the needle handle of the trocar (see part c in the figure) and the skin, which plays a protective role on the skin. Afterwards, the second sub-patch 13 is passed around the outside of the trocar handle and then stuck to the skin, so that the trocar handle is wrapped by the second sub-patch 13 and fixed. On the whole, the structural design is simple and reasonable. During use, the needle handle pad can isolate the needle handle of the trocar from the patient's skin, protecting the patient's skin from pressure sores. It improves the unhygienic phenomenon of cotton wool and silk threads caused by using torn cotton balls as pads in clinical practice. In addition, the needle handle of the trocar can be fixed by the second patch, which is very convenient and safe to use.
[0026] As a preferred embodiment, the main fixing patch 1 is a rectangular patch, and the first auxiliary patch 11 and the second auxiliary patch 13 are both rectangular patches provided along one end edge of the main fixing patch 1 .
[0027] In the above embodiment, the shape design of the main fixing patch 1 is simple, and the shape designs of the first sub-patch 11 and the second sub-patch 13 are adapted thereto. The first sub-patch 11 and the second sub-patch 13 are strip-shaped as a whole, and one end of the two is respectively connected to the two sides of one end of the main fixing patch 1 as a whole (only connected at the side end, and the rest of the part can be separated from the main fixing patch 1 for convenience of subsequent operations). The shape design is simple and reasonable. When not in use, the whole forms a rectangular patch, which is convenient for packaging and production.
[0028] In this embodiment, the corners of the main fixing patch 1 are rounded.
[0029] In this embodiment, the needle handle pad 12 can be a conventional medical cotton pad.
[0030] As a preferred embodiment, the thickness of the needle handle pad 12 gradually increases from one end close to the main fixing patch 1 to the other end.
[0031] In the above embodiment, since the end of the trocar handle away from the needle eye is generally in a tilted state after the needle is exposed, the thickness of the needle handle pad 12 is designed to be a gradual size, which is adapted to the direction of the trocar handle and can provide better support.
[0032] In this embodiment, the needle handle pad 12 is adhered to one side of the first secondary sticker 11 .
[0033] As a preferred embodiment, one side of the main fixing patch 1 , the first auxiliary patch 11 and the second auxiliary patch 13 is entirely covered with the first sterile release film.
[0034] In the above embodiment, the entire surface is adhered to the first sterile release film, which can achieve better packaging and sterile protection effects, and is also convenient and quick to tear open.
[0035] As a preferred embodiment, the second sterile release films on the other sides of the main fixing patch 1 , the first auxiliary patch 11 and the second auxiliary patch 13 are separated from each other.
[0036] In the above embodiment, the second sterile release film is designed as a split structure. During use, first tear off the second sterile release film on the other side of the main fixing patch 1, and stick the main fixing patch 1 near the needle eye (the middle of the edge line of one end of the main fixing patch 1 is close to the needle eye). Then, after the first sub-patch 11 passes through the gap between the trocar handle and the skin, tear off the second sterile release film on the other side of the first sub-patch 11, stick the first sub-patch 11 on the skin surface, and make the needle handle pad 12 well supported between the trocar handle and the skin. Next, tear off the second sterile release film on the other side of the second sub-patch 13, and make the second sub-patch 13 wrap the trocar handle from the outer surface, and stick it to the skin surface to fix it. The operation is more convenient, which improves the disadvantage that the first sub-patch 11 and the second sub-patch 13 are easily adhered to the skin during the whole tearing process of sticking the main fixing patch 1.
[0037] As a preferred embodiment, a pinching portion 14 is provided at the other end edge of the main fixing patch 1 for easy tearing off.
[0038] In the above embodiment, one side of the kneading portion 14 is not provided with an adhesive layer and will not adhere to the skin. When the main fixing patch 1 needs to be torn off, the medical staff can pinch the kneading portion 14 to tear off the main fixing patch 1 conveniently and quickly.
[0039] As a preferred embodiment, an easy-tear line (indicated by a in the figure) is provided between the first auxiliary sticker 11 and the second auxiliary sticker 13 and the edge line of one end of the main fixing sticker 1.
[0040] In the above embodiment, the tear line is not damaged when leaving the factory. When in use, the tear line between the first and second sub-patch 11, 13 and the main fixed patch 1 is torn apart through the tear line, so that the first and second sub-patch 11, 13 are only connected as a whole at the side ends of one end of the main fixed patch 1, which facilitates the subsequent operation of the first and second sub-patch 11, 13 bypassing the needle handle of the cannula needle and sticking them on the skin.
