Description
Technical field
The present invention relates to the two-way malleation infusion connector field of Needleless seal, particularly a kind of two-way positive pressure infuser of Needleless seal
Joint.
Background technology
Syringe, transfusion device and blood transfusion apparatus can be connected, it is especially useful in the patient of venous transfusion uses, such as children, critical illness
People, chemotherapy patients, the patient for continuing rescue and the patient for thering is water, electrolyte balance to lack of proper care.
At present, in existing technology, since the 1970s, it has been recognized that insecurely handle many shapes
The dangerous drug of the cancer of formula, as the Major health harm to the personnel of making up a prescription.There are the toxicity and length that report proves dangerous drug
Phase contact danger alopecia can be caused in medical personnel, fash is infertile, miscarriage, inborn defect even leukaemia or other
The cancer of form.In addition there are some researches show：Medical personnel and pharmaceutical factory worker may be faced with these medicines in whole cycle
Danger, whole cycle include, from distribution is fabricated onto, handling using waste in clinical or home care environment.Handle these medicines
Medical personnel may suck caused aerosol or dust during pharmacy and nursing supervision, or in unexpected acupuncture,
Overflow or during overflow is cleared up with direct skin contact, traditional medicine ordinance based on syringe needle and syringe in hospital ward
Material risk can be caused to the security of clinician and patient by having.Such as chemotherapeutics etc., there is heap file to prove a variety of
Medicine and its steam have very big bio-toxicity, and all these propose challenge, the production of ICU Medical, Inc. of the U.S. to clinic
Carry out good fortune positive pressure needle-free infusion products, be fluid input port respectively using three ends of T-shaped structure by taking CLC2000 types as an example
(needleless inserting mode, external spiral interface)；Decoction output end (inside spin interface)；Piston exhaust end.It can pull out after use defeated
While liquid joint, a malleation is produced in joint, forces liquid to be rinsed to intravenous rapidly, venous blood is left puncture needle, from
And avoid blood from being solidified in needle tubing, the unimpeded of remaining needle is kept, without using anticoagulant tube sealing.The product entered from 2002
After people China, found wide-spread favor in clinic, provincial hospital application is universal, and long-term defeated pin transfusion production liquid patient is even more to need.But
Because its is expensive, the patient for allowing to use is restricted.
In order to solve the above problems, closing pipe line is manufactured using specially designed machinery valve technology, to protect medical care people
Member and patient, including the connection of pin-free luer lock and connection needleless injector.When this great side research, exploitation, production it is two-way
When positive pressure connector and other needleless joints match, No leakage is provided with, no water clock is connected and disconnected from connecting.Two-way positive pressure connector
The transfer and effusion of environmental contaminants can mechanically be forbidden, medicine ordinance personnel may be coupled to needleless injector or needleless is defeated
The end of liquid pipe, and self automatic sealing whenever disconnecting, to protect the sealing of liquid container, material is free of latex
And DEHP, no dead space, the two-way positive pressure connector of valve sealing structure, it is widely portable to ICU, CCU, lazaretto ward, operating room
Deng clinical department, and production cost is greatly reduced, therefore, designing that a kind of two-way malleation infusion connector of Needleless seal has very much must
Will.
