Abstract
Abstract An injection system for suspensions and solutions having five cartridges supported on a cartridge support. The cartridges are connected to a coalescing disc with five inlet passages and a single output passage with a feed line connected to the single passage. Suspensions and solutions supplied to the cartridges are selectively injected into a test subject by supplying a saline solution to the cartridge from a syringe pump through a selector which selects the cartridge to which the saline solution is supplied.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
214 words
An apparatus for injecting suspensions and solutions into a test subject supply line, comprising: a cartridge support member; a plurality of cartridges secured to said support member; a coalescing disc having a single outlet passage connected to a plurality of inlet passages; means for connecting said test subject supply line to the single outlet passage of the coalescing disc; means for connecting each of said cartridges to one inlet of said coalescing disc; means for selectively supplying a measured amount of carrier solution sequentially to said cartridges to carry the suspension and solutions therein through the coalescing disc into the test subject supply line; said means for supplying carrier solution sequentially to the cartridges includes a sequencer having a cylinder block with one inlet passage and a plurality of outlet passages; means for connecting said outlet passages to said cartridges; means for sequentially connecting said inlet passage to said outlet passages and means for supplying measured amounts of solution to said inlet passage; said means for sequentially connecting said inlet passage to said outlet passages including a cylinder positioned within said cylinder block; said cylinder including a passage adapted to sequentially connect said inlet passage to said outlet passages; means for stepping the passage within said cylinder sequentially into alignment with said outlet passages.
Claim 2
Independent Claim
214 words
An apparatus for injecting suspensions and solutions into a test subject supply line, comprising: a cartridge support member; a plurality of cartridges secured to said support member; a coalescing disc having a single outlet passage connected to a plurality of inlet passages; means for connecting said test subject supply line to the single outlet passage of the coalescing disc; means for connecting each of said cartridges to one inlet of said coalescing disc; means for selectively supplying a measured amount of carrier solution sequentially to said cartridges to carry the suspension and solutions therein through the coalescing disc into the test subject supply line; said means for supplying carrier solution sequentially to the cartridges includes a sequencer having a cylinder block with one inlet passage and a plurality of outlet passages; means for connecting said outlet passages to said cartridges; means for sequentially connecting said inlet passage to said outlet passages and means for supplying measured amounts of solution to said inlet passage; said means for sequentially connecting said inlet passage to said outlet passages including a cylinder positioned within said cylinder block; said cylinder including a passage adapted to sequentially connect said inlet passage to said outlet passages; means for stepping the passage within said cylinder sequentially into alignment with said outlet passages.
Claim 3
Dependent Claim
74 words
The device as recited in claim 1 wherein said means for sequentially stepping the passage within the cylinder into alignment with the outlet passages includes a rachet wheel connected to said cylinder; an electric motor; means, connected to said electric motor for stepping said rachet wheel to move the passage within said cylinder from one outlet passage to the next for each revolution of said motor; means for stopping said motor after each revolution.
Claim 4
Dependent Claim
100 words
The device as recited in claim 2 wherein said means for stopping said motor after each revolution includes a cam wheel connected to said electric motor; a microswitch positioned adjacent said cam wheel; means for energizing said electric motor; said means for energizing said electric motor including a power supply; a relay, including switch contacts connected between said power supply and said motor; means, connected in parallel with said microswitch for energizing said relay to start said motor; said cam including means for closing the microswitch contacts for maintaining the energization of the motor for one revolution of the motor.
Claim 5
Dependent Claim
128 words
The device as recited in claim 3 wherein said means for supplying measured amounts of solution to the inlet passage of the cylinder block includes a syringe pump; a three way connector having a first port connected to the syringe pump; a solution supply; said three way connector having a second port connected to the solution supply; means, connected between the solution supply and the three way connector, for permitting only one way flow from the solution supply to the syringe pump; said three way connector having a third port connected to the inlet passage in said cylinder block; means, connected between the three way connector and said cylinder block inlet passage for permitting only one way flow from the syringe pump to the cylinder block inlet passage.
