Abstract

A medicinal fluid pooling device may be used to pool multiple containers of medicinal fluid to facilitate administration of the medicinal fluid to a patient. A medicinal pooling device may include spikes covered by spike sheaths which are pierced when a container of medicinal fluid is inserted into the medicinal pooling device. The medicinal pooling device may also include a cover configured to cover the spikes. The medicinal pooling device may also include a fluidic interface which may be used to fluidly connect the medicinal pooling device to an infusion pump or syringe.

First claim

1 - 85 . (canceled)

86 . A method of using a pooling device for pooling a medicinal fluid, comprising:
connecting a first container to a port, the port including a hollow spike and a spike sheath covering the spike, wherein the spike has a body including a first body portion and a second body portion, and a spike tip disposed on the first body portion, wherein the first body portion and the second body portion have different cross sectional shapes, wherein the second body portion is configured to create a fluidic seal with the spike sheath prior to connecting a container to the port, and wherein an internal channel of the spike extends through the first body portion and the second body portion, wherein connecting the first container to the port comprises pushing the first container onto the spike, causing the spike sheath and the first container to be pierced by the spike to allow fluidic communication between the spike and an internal volume of the first container, wherein pushing the first container onto the spike causes a force to be applied to the spike sheath, causing the spike sheath to compress and move towards a base coupled to the spike.

87 . The method of claim 86 , wherein the port includes a second hollow spike and second spike sheath covering the second spike, wherein connecting the first container to the port causes the second spike sheath and a second container to be pierced by the second spike to allow fluidic communication between a second internal volume of the second container and the second spike, wherein the second spike sheath forms a seal against the second spike, wherein the second internal volume contains a second medicinal fluid, wherein the second spike is in fluidic communication with second tubing.

88 . The method of claim 87 , further comprising coupling a syringe to the second tubing to cause the second medicinal fluid to move into the syringe.

89 . The method of claim 86 , further comprising:
connecting a second container to a second port, the second port including a second hollow spike and a second spike sheath covering the second spike, wherein connecting the second container to the second port comprises pushing the second container onto the second spike, causing the second spike sheath and the second container to be pierced by the second spike to allow fluidic communication between the second spike and an internal volume of the second container.

90 . The method of claim 89 , wherein the first container and the second container have different sizes.

91 . The method of claim 89 , wherein a volume of the first container is between 1.25 and 300 mL.

92 . The method of claim 91 , wherein the volume of the first container and a volume of the second container are each selected from the group of 5 mL, 10 mL, 20 mL, and 40 mL.

93 . The method of claim 86 , wherein the first body portion has a first major axis diameter and the second body portion has a second major axis diameter, wherein the first major axis diameter is larger than the second major axis diameter.

94 . The method of claim 86 , wherein the first body portion has a first minor axis diameter and the second body portion has a second major axis diameter, wherein the second major axis diameter is larger than the first minor axis diameter.

95 . The method of claim 86 , wherein the internal channel comprises an inlet and an outlet, wherein the inlet and the outlet are in fluidic communication via the spike sheath when the spike sheath is in an uncompressed position.

96 . The method of claim 86 , wherein the spike sheath includes a sheath base, a sheath shaft, and a sheath tip, and wherein the spike is received in the sheath shaft.

97 . The method of claim 96 , further comprising applying force to the spike sheath in a direction towards the base, which compresses the sheath shaft towards the base.

98 . The method of claim 97 , further comprising piercing the sheath tip with the spike when the sheath shaft moves toward the base.

99 . The method of claim 96 , wherein the spike sheath includes at least one sealing ring disposed in the sheath shaft.

100 . The method of claim 99 , wherein the sealing ring engages with a ledge on the spike.

101 . The method of claim 86 , wherein the first body portion has an elliptical cross sectional shape and the second body portion has a circular cross sectional shape.

102 . The method of claim 86 , further comprising removing a cover to expose the port prior to connecting the first container to the port.

103 . The method of claim 102 , wherein the cover includes a hinge, and the cover rotates between an open position and a closed position about the hinge.

104 . The method of claim 89 , further comprising removing a second cover to expose the second port prior to connecting the second container to the second port.
