Abstract

Fluid or blood administration equipment comprising, a plastic manifold, a plurality of flexible conduits connected at one end to said manifold and at their opposite ends each respectively connected to a bag for receiving blood, another flexible conduit connected to said manifold at one end with the opposite end of said flexible conduit adapted to be connected to a blood flow tube, another flexible conduit adapted to be connected at one end to said manifold with the opposite end thereof connected to an intravenous needle, with said pair of conduits leading to said blood bags having at their inner ends within said manifold a removable valve and with said manifold having a filter at the inner end of the conduit from the needle, and a band secured to said manifold whereby said band is strapped around the wrist or arm of the patient to prevent dislodgement of the needle if there should be any pull on the equipment.

Claims

1. Means for blood administration and the like which comprises, a manifold formed of a bag made of a transparent material which is generally pliable and which is inert and nontoxic, an inlet tube connected at one end to said manifold and a needle for insertion into the vein connected to the opposite end of the inlet tube, a blood receiving bag and a first tube connecting said manifold to said blood receiving bag, a blood flow tube and a second tube connecting said manifold to said blood flow tube, said first and second tubes being connected to said manifold at the end opposite said inlet tube connection, and filter means located within said manifold on said inlet tube, said manifold being of a size so as to be attached directly to the patient'"'"''"'"'s limb.

2. Means as set forth in claim 1 in which the end of the tube connecting the manifold to the blood receiving bag extends into the manifold with a ball valve inside said end of the tube for blocking the flow of blood into said tube, which ball valve may by manual pressure applied against the manifold and the end of the tube eject the ball valve from the tube into the manifold to unblock said tube.

3. Means as set forth in claim 1 in which there is a pair of blood receiving bags each connected by a tube to said manifold, which tubes have a ball valve inside the end of the tube within the manifold for blocking the flow of blood into said tube, which ball valve may by manual pressure applied against the manifold and the end of the tube eject the ball valve from the tube into the manifold to unblock said tube.

4. Means as set forth in claim 3 in which a band is adapted to encompass the hand or wrist of a patient so that accidental withdrawal of the needle from the patient is prevented.

5. Means for blood administration and the like which comprises, a manifold formed of a bag made of a transparent material which is generally pliable and which is inert and nontoxic, an inlet tube connected to one end of said manifold and a needle for insertion into the vein connected to the opposite end of the inlet tube, a blood receiving bag and a first tube connecting said manifold to said blood receiving bag, a blood flow tube and a second tube connecting said manifold to said blood flow tube, means connected to said manifold adapted to engage around the arm or wrist of a patient to prevent accidental removal of the needle from the patient.

6. Means as set forth in claim 5 in which the means adapted to engage around the arm or wrist comprises a band formed of flexible material having hooking means and cooperating attaching means.

7. Means as set forth in claim 5 in which the end of the tube connecting the manifold to the blood receiving bag extends into the manifold with a ball valve inside said end of the tube for blocking the flow of blood into said tube, which ball valve may by manual pressure applied against the manifold and the end of the tube eject the ball valve from the tube into the manifold to unblock said tube.

8. Means as set forth in claim 5 in which the means adapted to engage around the arm or wrist of a patient comprises a band of attaching members formed of Velero material whereby the opposite ends of the band are readily attachable and detachable from each other.
