Detailed Description

Example 1

As shown in fig. 1 to 4, a polylactic acid antibacterial bandage comprises a bandage main body 1, a buckle 2 and a clip 3, wherein the bandage main body 1 comprises a substrate 4 and a dressing layer 5 sewed on the substrate 4, the substrate 4 is a polylactic acid elastic gauze which is made of the existing material and is formed by mixing and spinning elastic filaments and polylactic acid fibers.

As shown in fig. 1, the dressing layer 5 is stitched to the substrate 4 in a patch-like manner and is located near the ends of the substrate 4 to facilitate dressing of the dressing layer 5 in alignment with the wound site. The surface of the dressing layer 5 is polylactic acid gauze, and polyurethane sponge is embedded inside. The dressing layer 5 may be square, circular or other conventional shape.

As shown in fig. 2, the clip 2 is sewn on the substrate 4, and the clip 2 comprises a clip leg 6, a web clip 7 and a clip seat 8 which are integrally formed. The buckle 2 can be a metal elastic sheet or an injection molding piece with a certain elastic deformation amount, and preferably, the injection molding piece is used for reducing the weight of the bandage and reducing the manufacturing cost.

Card foot 6 is sewed up on substrate 4 by foot tong "pan" 9, and foot tong "pan" 9 entangles card foot 6, and card foot 6 can overturn in foot tong "pan" 9, can overturn into upright state with buckle 2 during the use, conveniently inserts bandage main part 1 in the abdomen presss from both sides 7, then reverse winding bandage main part 1 again, adjusts into buckle 2 and crouches the state of falling towards the right side.

The card foot 6 is equipped with convex stopper 10 at the both ends of foot tong "pan" 9, and stopper 10 supports foot tong "pan" 9, prevents that card foot 6 from freely moving to the front and back direction.

The clamping feet 6 and the clamping seats 8 enclose a closed frame body. The root of the abdominal clamp 7 is connected with the clamp base 8, the free end of the abdominal clamp 7 can be opened when being subjected to external force, and the free end is pressed on the clamp base 8 in a free state to clamp the bandage main body 1 inserted into the abdominal clamp 7 between the abdominal clamp 7 and the clamp base 8.

Specifically, as shown in fig. 2 to 4, the clip 7 is of a plate-like structure, and the main body portion of the clip 7 is located within the closed frame, and the free end 11 of the clip is raised upward, facilitating rapid insertion of the bandage main body 1 under the clip 7. The free end 11 of the belly clip is provided with an inwards concave clamping groove 12, and when in use, the clamping groove 12 is extruded below the clamping seat 8, so that the belly clip 7 is bent and deformed, and the base material 4 is clamped.

The end part of the base material 4 is also sewed with a clip 3, and two ends of the clip 3 are bent inwards and used for clamping the end part of the bandage main body on the wound bandage main body 1.

When the bandage is used, one end of the bandage main body 1 is pressed, the dressing layer 5 covers a wound, then a circle of bandage is wrapped, the bandage main body 1 is inserted into the abdomen clamp 7 from the free end of the abdomen clamp 7, then the free end 11 of the abdomen clamp is pressed downwards and is pressed into the lower part of the clamp seat 8, the clamp groove 12 clamps the clamp seat 8, and at the moment, the abdomen clamp 7 reliably and firmly clamps the bandage main body 1; then reversely winding the bandage main body 1, and finally clamping the clip 3 at the end part into the wound bandage main body 1 to finish the bandage.

Example 2

The difference between this embodiment and embodiment 1 is that, as shown in fig. 5, the clip 7 is U-shaped, the clip 7 has two clip arms 13, one clip arm 13 on the right side is located in the closed frame, the other clip arm 13 on the left side is closely attached to the clip base 8, and a gap 14 for the bandage main body 1 to extend into is formed between the clip arms and the clip base 8. The part connecting the two arms 13 is the free end of the web clamp 7, which is also upturned, as in embodiment 1. The other structure of this embodiment is the same as embodiment 1.

When in use, one end of the bandage main body 1 is pressed, the dressing layer 5 is covered on a wound, and then a circle of dressing is bound; the free end of the abdominal clamp 7 is lifted by hand, the bandage main body 1 extends into the U-shaped structure of the abdominal clamp 7 from the notch 14 of the left clamping arm 13, and then the free end of the abdominal clamp 7 automatically returns to be matched with the clamping seat 8 to clamp the bandage main body 1; then, the bandage main body is arranged to be flat, the bandage main body 1 is wound reversely, and the bandage main body 1 is pulled by utilizing the clamping arms 13; finally, the clip 3 at the end part is clamped into the winding bandage main body 1 to complete the bandage.

Another application method is similar to that of the embodiment 1, one end of the bandage body 1 is pressed, the dressing layer 5 is covered on the wound, and then a circle is wrapped; the free end of the abdomen clamp 7 is lifted by hand, the bandage main body 1 is inserted between the clamping arm 13 on the right side and the clamping foot 6, and then the free end of the abdomen clamp 7 automatically returns to be matched with the clamp seat 8 to clamp the bandage main body 1; then reversely winding the bandage main body 1, and finally clamping the clips 3 at the end part into the wound bandage main body 1 to finish the bandage.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
