Abstract
Abstract An apparatus for connecting a vial into the delivery tube of an intravenous administration set, the set including a container of fluid connected to one end of a delivery tube with the other end of the delivery tube adapted for insertion into the patient. The apparatus includes a penetrating spike penetrating an end of the vial which provides two pathways into the interior of the vial with two sections of the delivery tube connected to the two pathways of the penetrating spike. The apparatus also includes a frame for maintaining the two sections of the delivery tube adjacent to each other and clamp for releasably closing the adjacent sections of the delivery tube to temporarily prevent flow of fluid through the penetrating spike.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
174 words
In an intravenous administration set comprising a container containing a fluid, a delivery tube connected to the container for dispensing fluid therefrom, injection means for connecting the delivery tube to a patient, a drip chamber situated in the delivery tube for permitting the determination of the administration rate of the fluid, and control means for controlling the administration rate of the fluid, the improvement comprising: a vial containing a medicine under a partial vacuum, penetrating means penetrating an end of the vial to provide two pathways to the interior of the vial, two adjacent sections of the delivery tube being arranged contiguous to each other and connected to the two pathways of the penetrating means, fluid flow restricting means situated in the delivery tube between the injection means and the penetrating means for permitting fluid flow into the vial only from said container, and means embracing said adjacent sections of the delivery tube for releasably closing both pathways to the interior of the vial to temporarily prevent flow of fluid through the penetrating means.
Claim 2
Dependent Claim
174 words

Claim 3
Dependent Claim
28 words
The improvement of claim 1 wherein the means for releasably closing to the two pathways comprises a clamp for simultaneously constricting the two sections of the delivery tube.
Claim 4
Dependent Claim
15 words
The improvement of claim 1 wherein the fluid flow restricting means comprises a particle/air filter.
Claim 5
Dependent Claim
16 words
The improvement of claim 3 wherein the fluid flow restricting means further comprises a check valve.
Claim 6
Dependent Claim
128 words
Apparatus for connecting a vial in the delivery tube of an intravenous administration set, the set including a source of fluid connected to one end of the delivery tube, the other end of which is adapted to be inserted in a patient, the apparatus comprising: penetrating means penetrating an end of the vial to provide two pathways to the interior of the vial, two sections of the delivey tube connected to the two pathways of the penetrating means, frame means for maintaining the two sections of the delivery tube adjacent to each other, and a clamp connected to the frame means and embracing both of said two sections for releasably clamping the adjacent sections of the delivery tube to temporarily prevent flow of fluid through the penetrating means.
Claim 7
Dependent Claim
128 words
Apparatus for connecting a vial in the delivery tube of an intravenous administration set, the set including a source of fluid connected to one end of the delivery tube, the other end of which is adapted to be inserted in a patient, the apparatus comprising: penetrating means penetrating an end of the vial to provide two pathways to the interior of the vial, two sections of the delivey tube connected to the two pathways of the penetrating means, frame means for maintaining the two sections of the delivery tube adjacent to each other, and a clamp connected to the frame means and embracing both of said two sections for releasably clamping the adjacent sections of the delivery tube to temporarily prevent flow of fluid through the penetrating means.
Claim 8
Dependent Claim
19 words
The apparatus of claim 5 further comprising filter means for filtering particulate matter and air from the delivery tube.
Claim 9
Dependent Claim
24 words
The apparatus of claim 5 further comprising flow restricting means for preventing fluid flow up the delivery tube from the patient to the vial.
Claim 10
Dependent Claim
130 words
Apparatus for connecting a vial in the delivery tube of an intravenous administration set, the set including a source of fluid connected to one end of the delivery tube, the other end of which is adapted to be inserted in a patient, the apparatus comprising: penetrating means penetrating an end of the vial to provide two pathways to the interior of the vial, two sections of the delivery tube connected to the two pathways of the penetrating means, frame means for maintaining the two sections of the delivery tube adjacent to each other, and clamping means for releasably clamping the adjacent sections of the delivery tube to temporarily prevent flow of fluid through the penetrating means, the clamping means including pivot means connecting the clamping means to the frame means.
Claim 11
Dependent Claim
130 words
Apparatus for connecting a vial in the delivery tube of an intravenous administration set, the set including a source of fluid connected to one end of the delivery tube, the other end of which is adapted to be inserted in a patient, the apparatus comprising: penetrating means penetrating an end of the vial to provide two pathways to the interior of the vial, two sections of the delivery tube connected to the two pathways of the penetrating means, frame means for maintaining the two sections of the delivery tube adjacent to each other, and clamping means for releasably clamping the adjacent sections of the delivery tube to temporarily prevent flow of fluid through the penetrating means, the clamping means including pivot means connecting the clamping means to the frame means.
Claim 12
Dependent Claim
157 words
Apparatus for connecting a vial in the delivery tube of an intravenous administration set, the set including a source of fluid connected to one end of the delivey tube, the other end of which is adapted to be inserted in a patient, the apparatus comprising: penetrating means penetrating an end of the vial to provide two pathways to the interior of the vial, two sections of the delivery tube connected to the two pathways of the penetrating means, a frame for receiving the two sections of the delivery tube, the tubes positioned by the frame to have divergent end portions offset from each other to maintain the vial in an inverted position and intermediate portions contiguous to each other for maintaining the two sections of the delivery tube adjacent to each other, the frame comprising clamping means for releasably clamping the adjacent sections of the delivery tube to temporarily prevent flow of fluid through the penetrating means.
