Abstract

Medical apparatus (10) for use with single use kits (100) containing a flow control device (101), a syringe (40), and one or more vials (60A, 608, 60C), for reconstituting a liquid drug dosage and administrating same. The flow control devices (101) include a core member (116) having an inlet port (107) and a flow control member (117) rotatably mounted on the core member (116) and having at least one vial port (112,113,114) for attachment of a vial and an outlet port (109). Flow control devices (101) are designed to ensure an inlet port (107) is in flow communication with a single port (112,113,114) at each flow control position of at least two predetermined flow control positions of a flow control member (117) relative to a core member (116). The medical apparatus (10) includes a housing (11) having a syringe support (12) for horizontally supporting a syringe (40) and a flow control device support (13) for horizontally supporting a flow control device (101). The medical apparatus (10) can be designed for either manual operation or automatic operation.

Claims

1. A flow control device for use with a syringe and at least one vial for reconstituting and administering a liquid drug dosage, the syringe having a reciprocal plunger with a proximal plunger head, the flow control device having a horizontal longitudinal axis and comprising:

(a) a stationary core member co-directional with the longitudinal axis and having an inlet port co-directional with the longitudinal axis for sealing fluid connection with the syringe and a pair of radial directed lumens perpendicular to the longitudinal axis and in flow communication with said inlet port,

said pair of radial directed lumens including a downward radial directed injection lumen for injecting liquid contents into a vial in flow communication therewith and an upward radial directed aspiration lumen for aspirating liquid contents from a vial in flow communication therewith; and

(b) an outer tubular flow control member rotatably mounted on said core member and having at least one peripheral located vial port for sealed attachment of a vial thereto and an administration flow channel in flow communication with an outlet port for administrating the liquid drug dosage,

the flow control device being operative such that said inlet port is in flow communication with a single port of said at least one vial port and said outlet port at each flow control position of at least two predetermined flow control positions of said flow control member relative to said core member for initially establishing a liquid drug reconstitution flow path between the syringe and each vial of the at least one vial for enabling initial reconstitution of the liquid drug dosage according to a liquid drug reconstitution program and subsequently establishing a liquid drug administration flow path between the syringe and the outlet port for administration of the liquid drug dosage according to a liquid drug administration regime.

2. The device according to claim 1, wherein said flow control member includes a driven cogwheel for rotating said flow control member relative to said core member.

3. The device according to claim 1, wherein each vial port of said at least one vial port is integrally formed with a vial adapter for snap fit receiving a vial.

4. The device according to claim 1, wherein said flow control member includes a set of at least two peripheral located vial ports deployed at the same length therealong.

5. A kit for reconstituting and administrating a liquid drug dosage, the kit comprising a flow control device according to claim 1, a syringe and at least one vial.

6. Medical apparatus for reconstituting and administrating a liquid drug dosage, the medical apparatus intended for use with a flow control device according to claim 1, a syringe having a reciprocal plunger with a proximal plunger head, and at least one vial, the medical apparatus comprising a housing including a syringe support for horizontally supporting a syringe and a flow control device support for horizontally supporting a flow control device.

7. Medical apparatus according to claim 6 and further comprising a controller for controlling the operation of:

a motorized syringe drive unit for selectively reciprocating a plunger head drive member engaging the plunger head for reciprocating the plunger relative to the flow control device, and

a motorized flow control device drive unit for selectively rotating the flow control member relative to the core member to a series of predetermined flow control positions for initially establishing a liquid drug reconstitution flow path between the syringe and each vial of the at least one vial for enabling initial reconstitution of the liquid drug dosage according to a liquid drug reconstitution program and subsequently establishing a liquid drug administration flow path between the syringe and the outlet port for administration of the liquid drug dosage according to a liquid drug administration regime.

8. Medical apparatus according to claim 7 wherein said controller reciprocates the flow control member back and forth relative to the core member for agitating a vial for reconstituting its powder contents.

9. Medical apparatus according to claim 7 wherein said controller is programmable for enabling manual input of said liquid drug reconstitution program.

10. Medical apparatus according to claim 7 wherein said controller is programmable for enabling manual input of said liquid drug administration regime.
