Description

Anti-pollution side hole type remaining needle

Technical Field

The utility model relates to the field of medical equipment, in particular to needle is kept somewhere to anti-pollution side opening formula.

Background

The vein is required to be used by various outpatients, emergency patients, ward patients and operation patients with various medicines, the vein is opened conventionally, and the medicines are required to be injected into the human body by a bolus injection or a pump injection through an indwelling needle. The tail of the existing indwelling needle is provided with two interfaces, one interface is used for connecting an infusion leather strip, and the other interface is specially used for intermittent dosing treatment in the treatment process; the two connectors are respectively provided with a cap in a conventional way, the cap needs to be taken down when dosing is carried out each time, and the cap covers the dosing connector after dosing is carried out; no matter the cap is taken down or covered, the inner side surface of the cap and/or a medicine adding interface of a remaining needle are easily touched, so that pollution is caused. Because the skin surface of a human body, a sickbed, bedclothing, a saline rod, a sickbed table and other equipment are all bacteria-bearing areas, bacteria enter the human body through skin damage or a remaining needle, and the infection in the hospital of a patient can be caused. When the medicine adding port cap is taken down, the inner side surface of the cap and the medicine adding port are generally touched and polluted by fingers of medical staff clinically, or the cap slides down to touch the skin surface of a patient, a sickbed, bed clothes, a saline rod, a sickbed table and the like to be polluted, and even occasionally, the cap rolls down on the sickbed of the patient or even on the ground to cause pollution. In addition, various natural actions of turning over the patient on a hospital bed and the like can easily cause the cap to fall off from the medicine adding interface, so that pollution is caused, and even bacterial viruses enter the human body along with the diffusion of the indwelling needle, and the patient cannot know the effect. When the dosing interface and the cap are polluted, the existing scheme cannot completely sterilize through iodophor disinfection, and on the other hand, the remaining needle dosing interface cannot be completely sterilized in all directions without dead angles due to the narrow pipeline; the remaining needle is also not likely to be pulled out and replaced again each time of pollution, so that the medical cost is increased on one hand, and the pain of the patient is increased on the other hand. It must be acknowledged that the intravenous drug adding link is still a weak link of aseptic operation at present, has huge hidden danger, is an important component of nosocomial infection, and particularly causes huge hidden danger to patients due to severe infection caused by outbreak of deep vein indwelling needles and various infectious diseases and viruses such as hepatitis, AIDS, syphilis and the like remained in corners of other patients in hospitals; the nosocomial infection brings about the use and even abuse of antibiotics, and the infection of some patients cannot be controlled and can be degraded into serious infectious diseases, thereby bringing about huge potential safety hazards to life.

Therefore, strict sterility is required for the administration procedure after vein opening. Clinical reality, urgent requirement this type of medical action reduces from the technology and adds medicine interface pollution risk, and the aseptic technique of guarantee ensures all having the absolute safety of traumatic medical action, surely can not bring any infection hidden danger to the patient, one kind can effectively standardize and add the medicine interface and use, avoids adding the anti-pollution side opening formula indwelling needle that medicine interface pollutes completely and becomes clinical urgent.
