Description

Combined type remaining needle sterilizer

Technical Field

The invention relates to the technical field of indwelling needle disinfection, in particular to a combined type indwelling needle disinfector.

Background

The venous indwelling needle is also called as venous trocar. The core components include a flexible catheter/cannula that can be indwelling in a blood vessel, and a stainless steel puncture guiding stylet. When in use, the catheter and the needle core are punctured into a blood vessel together, after the catheter completely enters the blood vessel, the needle core is withdrawn, and only the soft catheter is left in the blood vessel so as to carry out infusion treatment; the indwelling needle is divided into an open type and a closed type, the open type is divided into a common type and a safe type (a needle-prick prevention type), the closed type is divided into a common type and a safe type (a needle-prick prevention type), the puncture is easy, the related puncture technology is easy to learn and protect the blood vessels of patients, the pain of the patients is relieved, the feeling is comfortable, a plurality of different structural products can be selected for improving the satisfaction degree of the patients and the nursing quality, catheters with different lengths can be selected for improving the working efficiency of nurses to reasonably use the medicine, the condition that the patients do not use the medicine on time due to puncture when the transfusion is carried out for a plurality of times every day is avoided, the reaction between the medicines is avoided, the cost of the treatment is reduced, the cost of the exudation treatment caused by the puncture of a scalp needle is reduced, the pain and the fear of the puncture of the patients due to repeated veins can be reduced by the use of the indwelling needle, the anxiety of parents is relieved, the clinical medication is convenient for emergency rescue of the critical patients, and the workload of the nurses is reduced, the intravenous indwelling needle has the advantages that the pain of the children is reduced, so that the intravenous indwelling needle is widely applied clinically, the length of the indwelling time of the intravenous indwelling needle and the comfort of the children become the most concerned problems of nurses and parents in the face of the special group of the children, the intravenous indwelling needle is also the premise of successful use mark and popularization of the indwelling needle, and the disinfection and sterilization of the indwelling needle are particularly important when the indwelling needle is used.

At present, the existing indwelling needle disinfection has the following defects:

1. when the existing medical care personnel disinfect the indwelling needle, the positive pressure connector of the indwelling needle is mostly disinfected by adopting a disinfection cotton ball stained with disinfection alcohol, the disinfection cotton ball has strong adsorbability and can suck a large amount of alcohol, when the positive pressure connector is wiped, the alcohol on the cotton ball is easily dropped due to the action of pressure, meanwhile, the excessive alcohol is easily adsorbed on the positive pressure connector, the medical care personnel can inject the drug after the alcohol volatilizes, and the working efficiency of the medical care personnel is greatly prolonged;

2. in addition, the traditional manual disinfection mode is easy to cause the phenomenon of unclean disinfection and infection of patients.
