A blood collector system utilizes a standard disposable needle assembly and standard blood collecting and receiving tubes of the type sealed by a pierceable septum. The system has a hollow cylinder, including an internally apertured sleeve into which the needle assembly is mounted and into which the sealed blood collecting tubes are inserted to be pierced by a needle of the needle assembly. A protective sheath with two clips is concentrically mounted to the barrel cylinder with slot on both sides of the barrel so that the hollow cylinder can move down to cover the patent contacted needle. On both side of the barrel, there are one upper slot and one lower slot, a slot channel between the upper slot and lower slot. The clip is shaped so that it can be snap in the upper and lower slot and can be only slide down from the upper slot to lower slot, but not backwards. After the needle is taken out from a patient, the clip will be pushed down out of the upper slot, then slide down through the slot channel, then be pushed down to snap in the low slot of the barrel in order to cover the used needle from a patient.

An IV container spike and drip chamber assembly is provided that includes an automatic shut off mechanism which allows nurses to change the fluid container without removing the catheter from the patient. The automatic shut off mechanism comprises a floating ball capable of being supported by or floating in the fluid due to the buoyancy of the fluid. The IV container spike also includes an air vent which allows the air in the drip chamber to vent out directly when the nurses want to change the container of medicinal fluid. The air vent is closed for the initial use and during the infusion process. As the medicinal fluid is gradually reduced in level in the drip chamber, the floating ball is lowered thereby and when the floating ball reaches the bottom of the drip chamber, the floating ball blocks the outlet so as to stop the injection. After the injection is stopped nurses can take off the spike and insert it into a new medicinal fluid container, and open the air vent cap until the new medicinal fluid reaches the required level in the drip chamber. The air vent cap should be closed immediately after the medicinal fluid reaches the desired level.

A needleless connector for adding medication to a parenteral fluid is provided. The connector is provided with a male luer connector at one end and a female connector at the opposite end. A sliding plug valve is built into the connector so that the parental fluid may be isolated from the injection site to prevent back flow when the syringe is removed.
