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 collapsible bottle-like assembly. The fluid dispenser includes a unique stored energy mechanism which takes the form of a 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 collapsible fluid reservoir carried by said dispenser housing, said collapsible reservoir comprising a bottle having a telescoping sidewall, said bottle having an outlet port;

(iii) 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; and

(iv) dispensing means connected to said outlet port of said collapsible reservoir for dispensing fluid to the patient; 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 vial defining a fluid chamber containing a medicament and an elastomeric member movable within said fluid chamber between first and second positions.

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

3. The apparatus as defined in claim 1 in which said stored energy means comprises an expandable sponge operably interconnected with said collapsible reservoir.

4. 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.

5. The apparatus as defined in claim 1, further including a carriage assembly interconnected with said dispenser housing for movement between a first position and a second position, said collapsible fluid reservoir being carried by said carriage assembly.

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

7. The apparatus as defined in claim 1, further including fluid flow control means carried by said dispenser housing for controlling fluid flow from said collapsible reservoir toward said dispensing means.

8. The apparatus as defined in claim 7 in which said fluid flow control means comprises rate control means for controlling the rate of fluid flow from said collapsible reservoir toward said dispensing means.

9. 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 carriage assembly connected to said dispenser housing for movement between a first position and a second position;

(iii) a collapsible fluid reservoir carried by said carriage assembly, said collapsible reservoir comprising a telescoping bottle having an outlet port;

(iv) stored energy means carried by said dispenser housing and operably associated with said carriage assembly for moving said carriage assembly toward said second position;

(v) an administration set connected to said dispenser housing, said administration set including an administration line interconnected with said outlet of said collapsible reservoir; and

(vi) fluid flow control means carried by said dispenser housing for controlling fluid flow from said collapsible reservoir toward said administration set; 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 vial defining a fluid chamber containing a medicament and an elastomeric member movable within said fluid chamber between first and second positions.

10. The apparatus as defined in claim 9 in which said stored energy means comprises a pair of spaced-apart constant force springs operably interconnected with said carriage assembly.

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

12. The apparatus as defined in claim 9, further including guide means connected to said dispenser housing for guiding travel of said carriage assembly between said first position and said second position.

13. The apparatus as defined in claim 9 in which said fluid flow control means comprises rate control means for controlling the rate of fluid flow from said collapsible reservoir toward said administration set.

14. The dispensing device as defined in claim 13 in which said rate control means comprises a rate control plate having a plurality of fluid flow channels interconnected with said outlet of said collapsible reservoir.

15. The apparatus as defined in claim 13 in which said fluid flow control means comprises reservoir-accessing means for controlling fluid flow between said collapsible reservoir and said rate control means.

16. The apparatus as defined in claim 15 in which said outlet port of said reservoir is closed by a pierceable septum and in which said reservoir-accessing means comprises a penetrating member for penetrating said pierceable septum.

17. 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 carriage assembly connected to said dispenser housing for movement between a first position and a second position;

(iii) a collapsible fluid reservoir carried by said carriage assembly, said collapsible reservoir comprising a plastic bottle having a telescoping sidewall, said bottle having an outlet port;

(iv) stored energy means carried by said dispenser housing and operably associated with said carriage assembly for moving said carriage assembly toward said second position, said stored energy means comprising a spring; and

(v) fluid flow control means carried by said dispenser housing for controlling fluid flow from said collapsible reservoir toward said administration set; 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 vial defining a fluid chamber containing a medicament and an elastomeric member movable within said fluid chamber between first and second positions.

18. The apparatus as defined in claim 17 in which said stored energy means comprises a coil spring.

19. The apparatus as defined in claim 17 in which said stored energy means comprises a pair of spaced-apart constant force springs operably interconnected with said carriage assembly.

20. The apparatus as defined in claim 17 in which said vial of said vial assembly of said additive sub-system contains a diluent and a lyophilized drug.
