Description

Dark ductus venosus fixes protective sheath

Technical Field

The utility model belongs to the technical field of medical equipment, concretely relates to fixed protective sheath of dark ductus venosus.

Background

During hemodialysis treatment, the problem of fixing the deep venous catheter and how to ensure local cleanness and even sterility is involved. For example, the indwelling tube may slip due to improper protection, which may cause heavy bleeding of the patient, and if the indwelling tube is replaced, the pain and economic burden of the patient are increased, the fixation of the gauze is not firm, and the gauze is porous, which cannot protect the sterile surface. The adhesive plaster only can play a role in fixation, and cannot form a sterile surface, so that a patient feels uncomfortable and is easy to loosen.

The deep venipuncture indwelling catheter is one of the commonly used operation techniques in intensive care, and is one of the most effective ways for central venous pressure monitoring, transfusion, blood transfusion, hemodialysis and complete parenteral nutrition implementation of critically ill, major surgery and chronic consumptive disease patients.

The deep venous catheter is conventionally reserved for the jugular vein or the subclavian vein of a patient by a doctor, so that the medicine is convenient to be administered in time. But because the connector of dark ductus venosus is placed in patient's head side or neck side, critical patient often flows out saliva or vomit voluntarily on the one hand, and on the other hand nursing staff administers many times, stands up for the patient etc. can lead to the connector to pollute, or the transfer line drops from the connector, brings infusion potential safety hazard for the patient.

SUMMERY OF THE UTILITY MODEL

The utility model aims at: aims to provide a fixing protective sleeve for a deep venous catheter, which is used for solving the problems that the connector of the prior deep venous catheter is easily polluted and the infusion tube falls off from the connector.
