Description

Technical Field

[0001] This utility model relates to the field of medical dressing technology, specifically a composite dressing with a rigid substrate and its fixing device. Background Technology

[0002] After administering intravenous infusions, arterial blood draws, or venous blood samples, medical staff must stop the bleeding at the puncture site. Currently, there are two commonly used methods for stopping bleeding: one is applying pressure with a medical cotton swab; the other is applying pressure with an IV dressing. Both methods can potentially cause bleeding, subcutaneous bruising, swelling, and pain at the puncture site if the pressure is applied improperly. This not only causes unnecessary suffering for the patient but can also negatively impact future punctures.

[0003] Traditional cotton swab pressure methods often result in problems because the cotton swab is small in size and has a limited effective contact area. Operators tend to focus on pressing the needle puncture site on the skin surface while neglecting the puncture site in the blood vessel wall. Furthermore, the pressure applied by the cotton swab is uneven and prone to shifting, making it difficult to accurately press the needle puncture site, which frequently leads to bleeding and subcutaneous bruising.

[0004] Studies have shown that the intravenous patch compression method results in lower bleeding and bruising rates compared to the cotton swab compression method. Commonly used intravenous patch compression methods in clinical practice include thumb compression, hypothenar eminence compression, thenar eminence compression, three-finger compression, and four-finger compression. When performed by professionals, these methods significantly reduce bleeding and bruising rates. However, in practice, to save time for medical staff, the intravenous patch is often given to the patient or family member for compression. Because the intravenous patch is relatively soft and difficult to observe, it is inconvenient to hold and switch hands, and the actual compression effect depends on the finger position and the contact area with the wound. During the procedure, the person applying the compression may deviate from the puncture site, thus still potentially causing subcutaneous bruising.

[0005] Currently, there are two main methods for securing medical dressings: one is by using medical tape or the dressing's own adhesive; the other is by wrapping with bandages. With the former, when the dressing needs to be removed, the tape often sticks to the skin and hair around the wound, and sometimes the medical tape can cause skin allergies, leading to discomfort for the patient. The latter usually requires multiple layers of bandage, thus affecting the breathability of the wound and surrounding skin, hindering wound healing. Furthermore, wrapping and unwrapping bandages is cumbersome and inconvenient. Utility Model Content

[0049] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0050] Example 1

[0051] like Figure 1 and Figure 2 As shown, a composite dressing with a rigid substrate includes a substrate 1 and a dressing 5. The substrate 1 is made of non-metallic or ductile metal and has a rigid and deformable sheet structure under stress, wherein the non-metallic sheet can return to its initial shape after the external force is removed.

The area of ​​the substrate 1 is greater than 100 square millimeters. The area of ​​the dressing 5 is less than or equal to the area of ​​the substrate 1.

[0052] The dressing 5 includes cotton pads, cotton balls, gauze, non-woven fabric, alginate, hydrocolloid, hydrogel, and foam dressing; the dressing 5 is connected to the substrate 1 by adhesive, sewing, welding, or fiber winding; or, the dressing 5 and the substrate 1 are in a separate state before use, and the substrate 1 is combined with the dressing 5 when used.

[0053] In this embodiment, the substrate 1 is made of polyamide material and injection molded into a rectangular flat plate shape; the four corners of the substrate 1 are rounded; the thickness of the substrate 1 is preferably 0.6-1.0 mm; the area of ​​the substrate 1 is preferably 900-4800 square millimeters. The dressing 5 is made of cotton or non-woven fabric, the same size as the substrate 1, and is attached to the substrate 1 with medical adhesive. The outer surface of the dressing 5 is provided with a protective layer 15, which includes a protective film, release paper, packaging bag or packaging box; in this embodiment, the protective layer 15 is a plastic film.

[0054] In this embodiment, the dressing and substrate are much larger than traditional medical cotton swabs, providing sufficient margin of error. The substrate is rigid yet deformable under stress, making it easy to hold, switch hands, and apply pressure. Even ordinary patients can operate it accurately, easily locate and cover the wound, and apply more even pressure to the wound, thereby achieving effective wound pressure and rapid hemostasis.

[0055] Example 2

[0056] A composite dressing includes a dressing and a substrate, the substrate being a rectangular sheet structure. The substrate is made of a plastic metal, including stainless steel, aluminum, aluminum alloy, copper, and copper alloy; the surface of the substrate may also be coated with a medical polymer coating or a medical polymer film. Alternatively, the dressing substrate is composed of a plastic metal skeleton and a flexible non-metallic material; the metal skeleton includes metal strips, metal sheets, and metal wires; the flexible non-metallic material includes medical polymer films, non-woven fabrics, and textiles; the flexible non-metallic material is connected to the metal skeleton by adhesive bonding or wrapping.

[0057] like Figure 3 and Figure 4 As shown, the substrate 1 of the composite dressing in this embodiment is composed of medical nonwoven fabric 16 and aluminum alloy strip 17. The aluminum alloy strip 17 is designed in the shape of an I-beam and is attached to the side of the nonwoven fabric 16 by adhesive.

[0058] In this embodiment, the nonwoven fabric 16 can be used as a substrate for bonding with dressings or directly as a dressing. During use, the aluminum alloy strip 17, which serves as a metal skeleton, can be bent and pinched by hand to secure it to the patient's wound. It is suitable for wound dressing of small-diameter limbs such as fingers, toes, and wrists, as well as for special patients such as children, and the operation is quick and convenient.

[0059] Example 3

[0060] like Figure 5 and Figure 6 As shown, a composite dressing includes a substrate 1 and a dressing (not shown in the figure). The substrate 1 is made of a transparent material to form a rectangular sheet structure. The substrate 1 has a protruding surface 18 in the middle, which is a spherical surface or a boss structure with a flat end face. The spherical surface includes partial surfaces of a sphere and a rugby ball.

[0061] In this embodiment, the substrate 1 is made of transparent polycarbonate or polymethyl methacrylate. A spherical protrusion 18 is provided in the center of the front side of the substrate 1.

The protruding rings 2 have four grooves 3 and an outwardly protruding limiting ring 4 at the upper end of the protruding rings. This facilitates the connection of the composite dressing to the fixing device with insertion holes through the protruding rings.

[0062] The transparent substrate in this embodiment facilitates alignment of the puncture site and observation of the wound, simplifying the procedure. In cases where dressings are unavailable, contaminated, or the wound and bleeding are minimal, dressings can be omitted, and pressure can be applied directly to the patient's wound to stop bleeding. The substrate surface must be cleaned, disinfected, and sterilized before use.

[0063] Example 4

[0064] like Figure 7 and Figure 8As shown, a composite dressing includes a substrate 1 and a dressing 5. The substrate 1 is made of a rectangular planar sheet structure of medical polymer material, and the four corners of the substrate 1 are rounded. The front side of the substrate 1 is the dressing adhesion surface, and the back side of the substrate 1 is provided with a connecting structure, which includes a buckle, a plug, and a socket. The composite dressing is connected to a fixing device through the connecting structure.

[0065] In this embodiment, the base 1 is square, with a side length of 50 mm and a thickness of 0.8 mm, and the area of ​​the base 1 is approximately 2500 square millimeters. The connection structure of the base 1 is a plug, including two circular protruding rings 2 on the back of the base 1. The protruding rings 2 are evenly distributed with four grooves 3, and the upper end of the protruding rings 2 is provided with an outwardly protruding limiting ring 4. In use, the composite dressing is connected to the dressing fixing device with matching insertion holes through the protruding rings 2.

[0066] The dressing 5 includes cotton pads, gauze, non-woven fabric, alginate, hydrocolloid, hydrogel, and foam dressing; the dressing 5 is connected to the substrate 1 by adhesive, sewing, or welding; or, the dressing 5 and the substrate 1 are in a separate state before use, and the substrate 1 is combined with the dressing 5 and fixed by adhesive, bandage wrapping, or cable tie binding.

[0067] In this embodiment, the size and shape of the dressing 5 are the same as those of the substrate 1. The dressing 5 is made of a self-adhesive hydrocolloid. The outer surface of the dressing 5 is provided with a protective layer 15, which includes a plastic film, release paper, or a packaging bag. In this embodiment, the protective layer 15 is made of release paper.

[0068] Before using composite dressings, the dressing and the substrate are packaged separately, and then combined when needed. This method not only facilitates dressing production and packaging and makes it easier to replace contaminated dressings during use, but also allows for the reuse of the substrate, reducing unnecessary waste and aiding in waste sorting and recycling.

[0069] In this embodiment, the surface area of ​​the substrate and dressing is much larger than that of traditional medical cotton swabs, making it easy to locate the wound during use. The substrate also has sufficient rigidity for easy handling, switching between hands, and pressure application, resulting in uniform pressure. It is suitable for hemostasis after intravenous infusions and blood collection. Even ordinary patients can operate it accurately, achieving effective wound pressure and rapid hemostasis, making it very convenient to use.

[0070] Example 5

[0071] like Figures 9 to 11 As shown, a dressing fixation device includes a base 1, a dressing, and a cable tie for securing the dressing. The base 1 and the cable tie are both made of polyamide material, and the dressing is made of hydrocolloid. The base 1 and the dressing are rectangular, with the long side of the base 1 being 80 mm and the short side being 60 mm; the thickness of the base 1 is 1.0 mm.

[0072] The cable tie consists of a strap body 6 and a buckle body 7; the strap body 6 includes a connecting part 12, a toothed part and a tail part 10, the connecting part 12 is provided with a connecting hole 13 that matches the protruding ring 2 of the base body 1; the toothed part is provided with a plurality of first teeth 9 symmetrically on both sides.

[0073] The base 1 is connected to the belt 6 by the connecting hole 9 of the connecting part embedded in the protruding ring 2; the buckle 7 is provided with a T-shaped buckle hole 8; when the belt 6 passes through the buckle hole 8, the first tooth 9 of the belt 6 can form a snap-fit ​​connection with the edge of the buckle hole 8.

[0074] The buckle body 7 includes a main body 71 and a bent edge 72, the bent edge 72 being perpendicular to the main body 71; the bent edge 72 is provided with a T-shaped buckle hole or a rectangular strap hole 20, and the toothed part and the tail part 10 of the strap body 6 can freely pass through the rectangular strap hole 20.

[0075] In this embodiment, the connecting part 12 is provided with three connecting holes 13 and two structural holes 19; the back of the base 1 is provided with two circular protruding rings 2. The bent edge 72 of the buckle body 7 is provided with a rectangular through hole 20; the surface of the main body 71 is provided with two T-shaped buckle holes 8, wherein the lower buckle hole 8 is provided with an anti-loosening elastic baffle 14, and the toothed part of the belt body 6 passes into the buckle hole 8. The anti-loosening elastic baffle 14 can prevent the belt body 6 from coming off due to the rebound force generated by bending deformation.

[0076] The surface of the main body 71 of the buckle 7 is provided with a second tooth 11 that matches the first tooth 9 of the belt 6; the first tooth 9 of the belt 6 can also form a snap or embedded connection with the second tooth 11.

[0077] When in use, first connect the composite dressing to the tape body 6, then pass the tail 10 of the tape body 6 through the through hole 20 of the bent edge 72 and tighten it. At the same time, attach the tape body 6 to the surface of the main body 71 of the buckle body 7 so that the first tooth 9 of the tape body 6 and the second tooth 11 on the surface of the main body 71 form a snap-fit ​​connection.

[0078] This invention not only uses cable ties to connect and secure dressings, but also achieves physical hemostasis through the pressure of the cable ties, eliminating the need for continuous pressure from medical staff or patients. It is particularly suitable for hemostasis after arterial punctures and for bandaging wounds with significant bleeding, achieving rapid hemostasis. Compared to traditional arterial hemostasis devices, it has a simpler structure, is easier to operate, and allows for adjustable cable ties. It is safe and quick to use, while also reducing the workload of medical staff and improving work efficiency.
