Medical dressing for PICC (Peripherally Inserted Central Catheter)

Abstract

The invention provides a medical dressing for PICC (Peripherally Inserted Central Catheter). The medical dressing comprises at least one transparent film backing cloth; a sponge substrate layer which is composed of circular freeze-dried sponge is fixed on the film backing cloth; an elongated guide tube fixing opening for leading out and fixing a guide tube is formed between the circle center of the sponge substrate layer and the circumference in the radial direction; the opening end of the guide tube fixing opening is formed in the circumference; the length of the guide tube fixing opening is 20 to 45% of the radius of the sponge substrate layer; bactericide which is prepared from chlorhexidine digluconate or flamazine and at the mass concentration of 0.1 to 10% fills the sponge substrate layer. The dressing has the functions of absorbing liquid, inhibiting bacteria and stopping bleeding, is low in allergy rate and high in antibacterial permanence.

Description

technical field [0001] The invention relates to a medical dressing, in particular to a medical dressing for a peripherally inserted central catheter (PICC). Background technique [0002] Peripherally Inserted Central Catheters (PICC) is a catheterization technique in which a peripheral venous catheter is inserted and its tip is positioned in the superior vena cava or subclavian vein. Because the head of the PICC catheter is located in the central vein, the blood flow is large, and the fluid osmotic pressure and drug concentration can be rapidly reduced, thus avoiding the damage of chemotherapy drugs to peripheral blood vessels, stimulation of local tissues, and chemical phlebitis and chemical phlebitis caused by extravasation of chemotherapy drugs. Tissue necrosis. At the same time, PICC reduces the pain of repeated puncture for patients, effectively improves the quality of care and work efficiency, and avoids many hidden dangers of clinical infusion. It is especially suita...

AI Technical Summary

Problems solved by technology

This treatment method has the advantages of better catheter fixation and wound observation, but has the following defects: 1. There is still no effective treatment method for a large amount of exudate, so for patients with a large amount of catheter exudate, the frequency of nursing needs to be significantly increased, which increases the The workload of the nurses; second, the validity period of the sterilization after the puncture site is limited, and the bacteria colonized on the skin will continue to grow after 2-3 days, and the sustained antibacterial effect is limited, which significantly increases the incidence of catheter-related bloodstream infections; Third, it is necessary to use foreign objects to press the puncture port to stop bleeding, and the hemostatic effect is poor
