Novel blood sampling patch

Abstract

The invention discloses a novel blood sampling patch, which is made of a PU (Poly Urethane) material and is designed and manufactured according to a sterile blood sampling rule. A PU film has the advantages of waterproofness, air permeability, no sensitization, high elasticity, transparency and antibiosis. The entire blood sampling patch is a rectangle of which the length is 7 centimeters, the width is 6 centimeters and the edges are circular beads. In a water absorbing pad of which the length is 3.5 centimeters and the width is 3 centimeters, V-shaped stripping bottom paper with the width of2-3 centimeters and the length of 7 centimeters is designed particularly, an open side is overlapped with a bottom edge, and a folded side is close to the long side of the water absorbing pad. After a blood sampling needle is inserted, the three sides of the blood sampling patch adhere to the skin and cover a needle eye, so that infection is prevented. During needle pulling, the blood sampling needle is prevented from adhering to the blood sampling patch since the V-shaped stripping bottom paper is used for partitioning. After the needle is pulled out, the V-shaped bottom paper is stripped off, and the four sides of the blood sampling patch adhere to the skin, so that the needle eye is prevented from being infected. The PU film is soft and comfortable, and is particularly suitable for protecting during elbow blood sampling. The PU film is transparent and perspective, so that the bleeding stopping situation on the needle eye, swelling, infection and the like can be observed conveniently. The novel blood sampling patch can be kept for over 24 hours.

Description

technical field [0001] The blood bank system collects blood from voluntary blood donors, and other medical institutions use it for blood collection by venipuncture. Background technique [0002] At present, all medical institutions across the country use Band-Aids, transfusion patches, and sterile cotton balls when venipuncture and unpaid blood donors donate blood. . . etc. Due to the long time of blood collection and infusion, according to the requirements of aseptic operation procedures, the needle hole must be covered during the puncture process to prevent bacteria and dust from polluting the needle hole in the air and on the body of the medical staff. Band-aids, infusion patches, sterile cotton balls, etc. cannot meet the requirements due to design limitations. Some use non-woven dressings, the size of which is sufficient to cover the eye of the needle. However, when the needle is pulled out after the puncture is completed, due to the adhesion of the needle and the dr...

Problems solved by technology

Band-aids, infusion patches, sterilized cotton balls, etc. cannot meet the requirements due to design limitations

Some use non-woven dressings, which are large enough to cover the eye of the needle, but when the needle is pulled out after the puncture, the needle is glued to the dressing, resulting in poor needle extraction, shifting of the dressing, and contamination around the eye of the needle.

The non-transparent material dressing is easy to warp and fall off when pasted on the elbow, and it is difficult to observe whether there is bleeding, redness, swelling, infection, etc.
