Embodiment 1
[0042] Embodiment one: see attached figure 1 Shown:
[0043] A method for manufacturing an infusion indwelling device connector that reduces nosocomial infections, comprising the following steps:
[0044] Step 1: Preparation of the steel needle 1: produce a steel needle 1 with a conical needle tip, the opening of which is located on the side wall of the needle tube behind the rear edge of the conical needle tip; the diameter of the steel needle 1 is 0.7 mm.
[0045] The second step: bonding the steel needle 1 and the needle holder 2 .
[0046] Step 3: or further bond or heat seal or weld or assemble with other components, pack, sterilize, and pass the inspection to obtain the indwelling infusion connector.
[0047] During use, the steel needle 1 is inserted towards the end face of the puncture-type connecting piece and inserted to the bottom. Because the steel needle 1 with a conical needle point is used, the probability of nosocomial infection is greatly reduced. The inje...
Embodiment 2
[0048] Embodiment two: see attached figure 1 , 2 , as shown in 4:
[0049] A method for manufacturing an infusion indwelling device connector that reduces nosocomial infection, the manufacturing method includes the following steps:
[0050]Step 1: Preparation of the steel needle 1: produce the steel needle 1 with a conical needle tip, the opening of which is located on the side wall of the needle tube behind the rear edge of the conical needle tip; the diameter of the steel needle 1 is 0.4mm or 0.6mm.
[0051] The second step: the 0.4mm steel needle 1 is bonded to the injection needle seat or the 0.6mm steel needle 1 is bonded to the infusion needle seat.
[0052] Step 3: Assembling with the injection barrel or bonding the infusion catheter 3 and bonding or assembling the conventional protective cap 6 and other accessories, packaging, sterilizing, and passing the inspection to obtain the infusion indwelling part infusion needle / device or syringe.
[0053] During use, the co...
Embodiment 3
[0054] Embodiment three: see attached figure 1 , 3 Shown:
[0055] A method for manufacturing an infusion indwelling device connector that reduces nosocomial infection, the manufacturing method includes the following steps:
[0056] Step 1: Preparation of the steel needle 1: produce the steel needle 1 with a conical needle tip, the opening of which is located on the side wall of the needle tube behind the rear edge of the conical needle tip; the diameter of the steel needle 1 is 0.5mm or 0.8mm.
[0057] The second step: the 0.5mm steel needle 1 is bonded to the injection needle seat or the 0.8mm steel needle 1 is bonded to the infusion needle seat.
[0058] Step 3: After assembling with the injection device or bonding the infusion catheter 3 and other accessories, performing bonding or assembling, packaging, sterilizing, and passing the inspection, the infusion needle / device or syringe of the indwelling part for infusion is obtained.
[0059] In this example, the infusion n...
