The medicine waste is avoided, no dead angle exists in a needleless connector, the residual liquid medicine is only 0.06 ml, the waste of expensive medicines can be avoided, the accuracy of the medicine dosage is ensured, and the economic loss of a patient is reduced.
The operation is convenient, the needle-free joint is simple and convenient to operate, the transfusion can be interrupted at any time, and the connection of the transfusion for the second time is easy. The puncture needle is not needed to puncture the heparin cap during safe, economical and practical operation, so that tiny particles are prevented from entering the transfusion system; the needleless connector is designed with a unique sealing valve device, so that the potential risk of air suction can be reduced; the needle-free joint does not need to use an infusion needle, so that accidental injury can be effectively avoided, and the chance that medical care personnel and patients are punctured by the needle is reduced; the needleless connector is used, so that the blockage of an indwelling catheter can be reduced, and the repeated puncture frequency is reduced, thereby relieving the pain of a patient; the needleless connector has the use validity period of 7-10 days, replaces disposable consumables such as an infusion needle, an injector, a heparin cap and the like, and saves tube sealing liquid such as normal saline, heparin sodium and the like; the needleless connector can provide enough flow, and the maximum flow can reach 200 ml/min. Is safe, convenient, economical and practical for patients with long-term transfusion.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a malleation connects, simple structure, convenient to use, malleation connect need not use anticoagulant tube sealing after pulling out the transfusion system down, reduced the inconvenience that a lot of bloodletting for medical personnel brought, the multichannel function that malleation connects can reduce a lot of bloodletting, and the medicine is annotated many times, brings the convenience for nursing staff work, and the probability that malleation connects the jam is zero, reduces the syringe needle simultaneously and blocks up and need puncture repeatedly's work load. The utility model discloses an adopt following technical scheme to realize: a positive pressure joint comprises a positive pressure joint base 1, a positive pressure valve 2 and a positive pressure joint upper base 3. The positive pressure joint base 1 is provided with the positive pressure valve 2, and the positive pressure joint base 1 and the positive pressure valve 2 are solidified and bonded through UV glue, so that liquid (gas) leakage of a product can be effectively avoided; the positive pressure joint base 1 and the positive pressure valve 2 are assembled and then welded and assembled with the positive pressure joint upper base 3 through an ultrasonic welding machine. The positive pressure joint base 1 is provided with a groove matched with a boss of the positive pressure joint upper base 3, and the positive pressure valve 2 is internally provided with a rib position 4, so that the positive pressure valve has higher resilience coefficient and stronger elasticity; the angle between the main cavity and the side cavity of the positive pressure joint upper seat 3 is 35 degrees, so that the packaging sealing angle is reduced, and the risk of poor packaging heat synthesis type sealing is reduced; the positive pressure joint base 1 and the positive pressure joint upper base 3 are welded and fixed through an ultrasonic welding machine, and the product is more stable and firm.
The utility model discloses the malleation connects, and malleation joint base passes through the solidification bonding of UV glue with positive pressure valve. The connection is reliable, the manufacturing process is simple, and the product quality is stable.
