Abstract

A compact fluid dispenser for use in controllably dispensing fluid medicaments, such as, antibiotics, analgesics, and like medicinal agents from the device reservoir which is provided in the form of a novel bellows-type assembly. The fluid dispenser includes a unique stored energy mechanism which takes the form of a constant force spring member of novel design that provides the force necessary to continuously and substantially uniformly expel fluid from the device reservoir. The device also includes novel adjustable flow rate control assembly that is disposed intermediate the fluid reservoir outlet and the outlet port of the device for precisely controlling the rate of fluid flow from the outlet port toward the patient.

Claims

1. An apparatus for dispensing medicaments to a patient comprising:

(a) A fluid dispensing unit comprising;

(i) a dispenser housing, including a connector portion;

(ii) a reservoir-defining assembly formed in accordance with an aseptic blow-fill-seal manufacturing technique and comprising a collapsible container having a collapsible fluid reservoir carried by said dispenser housing, said collapsible container having an outlet port and including a top wall, a bottom wall, and a side wall interconnecting said top and bottom walls, said collapsible container further including a neck portion connected to said top wall, said neck portion being sealed by a closure wall;

(iii) dispenser stored energy means carried by said dispenser housing and operably associated with said collapsible reservoir for collapsing said collapsible reservoir to expel fluid from said outlet port of said collapsible reservoir;

(iv) dispensing means connected to said outlet port of said collapsible reservoir for dispensing fluid to the patient; and

(v) fluid flow control means carried by said dispenser housing for controlling fluid flow from said collapsible reservoir toward said dispensing means, said flow control means comprising;

a. rate control means carried by said dispenser housing for controlling the rate of fluid flow from said collapsible reservoir toward said dispensing means, said rate control means comprising rate control plate having a plurality of fluid flow channels interconnected with said outlet of said collapsible reservoir; and

b. operating means carried by said dispenser housing for controlling fluid flow between said collapsible reservoir of said fluid dispensing unit and said rate control means, said operating means comprising a penetrating member having a fluid flow passageway and a control knob rotatably carried by said dispenser housing for causing said penetrating means to penetrate said closure wall of said collapsible container; and

(b) an additive sub-system removably connected to said fluid dispensing unit for adding fluid to said collapsible fluid reservoir of said fluid dispensing unit, said additive sub-system comprising;

(i) a connector housing removably connected to said connector portion of said dispenser housing of said fluid dispensing unit; and

(ii) a vial assembly removably receivable within said connector housing, said vial assembly comprising a blow-molded, collapsible fill vial having a closure wall and a collapsible sidewall defining a fluid chamber containing a medicament, said fluid chamber having an outlet port.

2. The apparatus as defined in claim 1 in which said additive sub-system further comprises a stored energy means carried by said connector housing and operably associated with said vial for collapsing said collapsible sidewall, thereof, to expel fluid from said outlet port of said fluid chamber.

3. The apparatus as defined in claim 1 in which said dispenser stored energy means comprises a spring operably interconnected with said collapsible reservoir.

4. The apparatus as defined in claim 1 in which said collapsible sidewall of said vial comprises a bellows structure.

5. The dispensing apparatus as defined in claim 1 in which said collapsible sidewall of said vial comprises a telescoping side wall.

6. The apparatus as defined in claim 1 in which said collapsible fluid reservoir of said fluid dispensing unit comprises a bellows structure.

7. The apparatus as defined in claim 1 in which said dispensing means comprises an administration set, including an administration line interconnected with said outlet of said collapsible reservoir of said fluid dispensing unit.

8. The apparatus as defined in claim 1, in which said fluid dispensing unit further includes a carriage assembly interconnected with said dispenser housing for movement between a first position and a second position, said collapsible fluid reservoir of said fluid dispensing unit being carried by said carriage assembly.

9. The apparatus as defined in claim 1 in which said vial of said vial assembly of said additive sub-system contains a diluent.

10. An apparatus for dispensing medicaments to a patient comprising:

(a) A fluid dispensing unit comprising;

(i) a supporting structure, including a connector portion;

(ii) a carriage assembly carried by said supporting structure for movement between a first position and a second position;

(iii) a reservoir-defining assembly formed in accordance with an aseptic blow-fill-seal manufacturing technique and comprising a hermetically sealed, collapsible container carried by said carriage, said collapsible container having a fluid reservoir for containing the fluid to be delivered to the patient, said fluid reservoir having an outlet port, said collapsible container including a top wall, a bottom wall, and a collapsible side wall interconnecting said top and bottom walls, said collapsible container further including a neck portion connected to said top wall, said neck portion being sealed by a closure wall;

(iv) a dispenser stored energy means operably associated with said carriage assembly for movement of said carriage assembly between said first position and second positions;

(v) an administration set, including an administration line interconnected with said outlet port of said collapsible reservoir; and

(vi) fluid flow control means carried by said supporting structure for controlling fluid flow from said collapsible reservoir toward said administration set, said flow control means comprising;

a. rate control means carried by said supporting structure for controlling the rate of fluid flow from said collapsible reservoir toward said administration set, said rate control means comprising rate control plate having a plurality of fluid flow channels interconnected with said outlet of said collapsible reservoir; and

b. operating means carried by said supporting structure for controlling fluid flow between said collapsible reservoir of said fluid dispensing unit and said rate control means, said operating means comprising a penetrating member having a fluid flow passageway and a control knob rotatably carried by said supporting structure for causing said penetrating means to penetrate said closure wall; and

(b) an additive sub-system removably connected to said fluid dispensing unit for adding fluid to said collapsible fluid reservoir of said fluid dispensing unit, said additive sub-system comprising;

(i) a connector housing removably connected to said connector portion of said dispenser housing of said fluid dispensing unit; and

(ii) a vial assembly removably receivable within said connector housing, said vial assembly comprising a blow-molded, collapsible fill vial having a closure wall and a collapsible sidewall defining a fluid chamber containing a medicament, said fluid chamber having an outlet port.

11. The apparatus as defined in claim 10 in which said collapsible sidewall of said vial comprises a bellows structure.

12. The dispensing apparatus as defined in claim 10 in which said collapsible sidewall of said vial comprises a telescoping side wall.

13. The apparatus as defined in claim 10, in which said vial assembly further comprises a check valve for controlling fluid flow between said outlet port of said fluid chamber and said collapsible fluid reservoir of said fluid dispensing unit.

14. The apparatus as defined in claim 10, in which said vial assembly further comprises a carriage assembly moveable between a first position and a second position, said vial being carried by said carriage assembly.
