Description

Catheter fixing dressing

Technical Field

The utility model relates to the technical field of medical supplies, in particular to a catheter fixing dressing.

Background

The technical operation Specification for intravenous therapy and nursing clearly requires: before vein treatment is performed on different diseases, nursing staff should evaluate the age, illness state, allergy history, vein treatment scheme and the like of patients, drug properties, treatment time and the like, select proper drug infusion routes and vein treatment tools, evaluate skin conditions and vein conditions of puncture parts, and select thinner and shorter catheters as far as possible under the condition of meeting treatment requirements. The venous indwelling needle is simple and convenient to operate, is suitable for puncturing at any position, simultaneously relieves the pain of repeated puncturing of patients, reduces the workload of nursing staff, and is popular with patients in clinic. With the widespread popularization and use of intravenous catheters, phlebitis, one of the complications that occurs with clinical intravenous catheters, is a non-negligible problem.

Such as bacterial phlebitis, which is usually related to incorrect sterilization methods, bad puncture techniques, destruction of sterile state of infusion cannula, overlong retention time of catheter, common symptoms of phlebitis, namely red, swelling, heat and pain of blood vessel at puncture position, vein like ropes should roll, slide and be inelastic when touching, purulent secretion can be extruded out from local needle eyes of serious patients, and systemic symptoms such as fever can be accompanied, at present, the method for fixing the clinical venous indwelling needle is various, and the method comprises medical adhesive tape fixing, wound bandage winding and bandage fixing, wrist mesh bandage fixing, gauze wrapping, transparent dressing fixing and the like. However, when a large amount of medical adhesive tapes are used for fixation, allergic reactions such as skin redness and swelling occur to partial patients; the wound bandage is fixed by winding the bandage, which covers the symptom of complications, influences the blood circulation and the transfusion speed and is unfavorable for clinical treatment. Transparent dressing commonly used clinically is well-appreciated by patients due to its high breathability, low sensitization and extensibility. However, the transparent dressing does not have functionality: such as bacteriostasis, pain relieving and hemostatic properties, thus when red swelling, pain and bacterial infection occur at the puncture site of the venous indwelling needle, nursing staff is required to frequently change dressing, and skin around the needle eye is required to be strictly disinfected with iodine and alcohol every day, so that the workload of the nursing staff is increased, and psychological anxiety and physical pain are brought to patients due to bacterial infection and inflammation.
