Description
Technical Field
The utility model relates to the technical field of medical appliances, in particular to a central venous catheter protection and fixation dressing.
Background
The central venous catheter (Central venous catheter, CVC) and the central venous catheter (PERIPHERALLY INSERTED CENTRAL CATHETER, PICC) are placed through peripheral veins and are used as a common administration mode for clinical critical patients and tumor patients, the administration mode can remarkably improve the pain of the patients caused by repeated puncture due to long-term acceptance of nutritional medicines or other medicaments, and the administration method can reduce the irritation of high-concentration medicines such as irritant medicines to the blood vessels of the patients and improve the treatment effect on the patients. However, clinical experience shows that if the CVC and PICC cannot be effectively fixed after the patient is punctured, adverse reactions such as infection, local seepage, pipeline displacement, falling-off and the like can be caused to the patient, and the treatment effect is affected to a certain extent. 60% of nosocomial blood flow infections originate from vascular access devices, and 90% of catheter-related blood flow infections (CRBSIs) in the icu (intensive care unit) are caused by CVCs or PICCs (central venous catheter placement via peripheral veins).
Therefore, in order to meet the drug treatment requirements of ICU critical patients and tumor patients, the drug infusion device has the advantages of safety, comfort, convenience and the like, so that the drug infusion device is suitable for patients needing repeated input of stimulatory drugs or long-term infusion. After the catheter is placed, the problems of bleeding, seepage and the like of the puncture point are more prominent and common, and sometimes the protective dressing needs to be replaced once even for a few hours. Frequent dressing changes undoubtedly increase the chance of catheter infection, causing serious complications. The existing clinical catheter fixing method is not suitable for fixing various catheters; moreover, at present, no proper and convenient fixed dressing can meet the requirements of firm catheter fixation, convenient observation of puncture points, measurement of exposed length of the catheter, and stronger adsorption, blood permeation, liquid permeation and the like when the catheter is observed at any time. Meanwhile, in the prior art, when the central venous catheter is used, the central venous exposed catheter is difficult to fix and protect. Moreover, the protection of the central vein exposed catheter in the prior art is insufficient, and for patients requiring long-term resident PICC catheter regular chemotherapy of tumor patients, effective protection and fixation of the exposed catheter are key to protecting the PICC catheter to prolong the resident time and service life during the intermittent period of the tubular resident chemotherapy.
For this reason, there is a clinical need for a dressing that is effective in establishing a sterile barrier for a patient and protecting a catheter puncture site to reduce the problems of directly causing catheter-related blood flow infections (CRBSIs) to occur due to infection of the puncture site wound. The key to preventing and controlling local infections is wound care and dressing choice, so the use of a suitable catheter-fixed dressing is of great importance to central venous catheter patients. That is, there is a great clinical need for a dressing that can effectively protect and secure a central venous catheter, thereby preventing contamination, and which can facilitate the observation and assessment of the catheter.
