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.

Claims24

Dependent claims

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.
