Description
Technical field
The present invention relates to medical appliance fields, and in particular to a kind of needleless joint microorganism invasion tester and its user
Method.
Background technology
With the development of modern medical service technology, clinically application obtains universal original having needle to vein detaining needle for fluids infusion mode
Transfusion system cannot fully meet the needs of domestic clinic, and the appearance of Needleless seal transfusion technology, compensate for needle infusion
Deficiency of the system in clinic, makes gradually to replace backward needle to pierce using needleless connection in infusion connection system and connects into order to can
Energy.Needleless connection (infusion) technology refers to not using the mode of puncture of steel needles calparine cap in infusion system to be attached.Nothing
Needle closed transfusion technology no longer makes be attached with the mode that needle pierces in infusion system, will have needle infusion connection to be changed to needleless
Infusion connection can avoid the accidental injury generated when needle thorn, simplify mode of operation, mitigate the labor intensity of medical staff, protects patient
Vein blood vessel safeguards medication access, contaminates professional risk to reducing operating personnel's picotement, mitigates medical staff's labor intensity, carry
High working efficiency and the equal important in inhibiting of therapeutic quality.
Clinically it is required for the disinfectant program provided according to manufacturer to carry out disinfection it using before needleless interface every time.
If manufacturer provide disinfectant program is inappropriate or needleless interface there are design defect, the microorganism of interface may
Into fluid path and bloody path system, patient body health is influenced.Microorganism invasion experiment must be carried out for this kind of instrument, with to manufacture
Disinfectant program and the needleless interface design that quotient provides carry out overall merit.The microbial species to be checked of the microorganism invasion experiment of connector
Class is gram-positive bacteria, staphylococcus epidermis, staphylococcus aureus, pseudomonas aeruginosa, Klebsiella Pneumoniae and Bao Man
Several most common pathogens of acinetobacter calcoaceticus.
Needleless interface is often attached with Rule attachment device.According to the standard of ISO594, the distal end of medicament delivery device
Tip is cone and presents and be tapered 6%, therefore constitutes the protrusion that can be called Rule attachment device.Rule connects
The recess portion of device be such as accordingly to be connected to distal tip needle holder be tapered 6% hole.Such Rule connection
Device allows the connection of the No leakage between medicament delivery device and such as needle holder, and provides protection against them and contain
Liquid product pollution.In YY/T 0923《Fluid path, bloody path needleless interface microorganism invasion test method》Have in standard following
Regulation:For a test specimen, under aseptic technique, the following tests period is carried out again and again by hand:1) it takes
There is a syringe of luer lock outer cone conehead, extracts 10mL sodium chloride injections (or using there is locking-type outer cone cone
The disposable pre-encapsulated injector of head);2) the locking-type outer cone conehead of syringe is screwed in for trying needleless joint;3) to for examination
10mL sodium chloride injections are injected in needleless joint;4) the luer lock outer cone of syringe is screwed off from for examination needleless joint
Conehead.
Since test requirements document carries out the inspection of a variety of bacterial strains.For each bacterial strain, the inspected number of every batch of sample is at least 5
Even 20 samples.It may need to repeat the above-mentioned test period nearly 100 times per a sample.With no-needle transfusion connector
Product is more and more, and reviewer's workload can be more and more heavier.And manual operation experiment during be easy to bring it is cumbersome,
The problems such as be easy to causeing introducing artificial pollution, influencing test result, in order to avoid needing to use disposable inoculated with reduction pollution
Syringe (about more than ten yuan every) is sealed, this leads to excessively high experimentation cost, waste of manpower and time.Therefore, there is an urgent need to develop
