1. An apparatus for delivering fluid to a mammal'"'"'s body, comprising:
- a reusable part comprising;
a reusable housing including a first portion and a second portion;
a first part of a pump contained within the first portion of the reusable housing, wherein the first part comprises a stator stpported by a spring;
a second part of the pump contained within the second portion of the reusable housing, wherein the second part of the pump comprises a rotary wheel with rollers; and
a disposable part removably insertable into the reusable housing, the disposable part comprising at least a reservoir containing the fluid, and a fluid delivery tube;
wherein the first portion of the reusable housing and the second portion of the reusable housing are configured together in a hinged arrangement for relative pivoting displacement between an open position in which the pump is disabled and a closed position in which, when the disposable part is inserted within the reusable housing, the pump is enabled, andwherein upon insertion of the disposable part into the housing, and relative displacement of the first portion and the second portion from the open position to the closed position, at least portion of the delivery tube is pressed against the rotary wheel by the stator thereby effecting peristaltic pumping.

Abstract
Methods, systems, and apparatuses for delivering therapeutic fluid to a user are disclosed. The apparatus includes a pump mechanism for pumping therapeutic fluid to the user having a reusable part which includes a housing and a disposable part configured to be inserted into the housing of the reusable part and to be connected with the reusable part. The connection of the reusable part and the disposable part enables operation of the pump mechanism and disconnection of the reusable part and the disposable part disables operation of the pump mechanism.

25. An apparatus for delivering fluid to a mammal'"'"'s body, comprising:
-
first part of a pump contained within a first portion of a housing, wherein the first part comprises a stator supported by a spring; a second part of the pump contained within a second portion of the housing, wherein the second part of the pump comprises a rotary wheel with rollers; and at least one component, separate from the portions of the housing, configured for removable insertion into the housing so as to be entirely contained within the housing when inserted, the at least one component including a fluid delivery tube; wherein; the first portion of the housing and the second portion of the housing are configured together in a hinged arrangement for relative pivoting displacement between an open position and a closed position, the at least one component is configured to operatively couple to the first and second parts of the pump upon inserting the at least one component into the housing and displacing the first and second portions of the housing from the open position to the closed position, and upon insertion of the at least one component into the housing, and relative displacement of the first portion and the, second portion from the open position to the dosed position, at least portion of the delivery tube is pressed against the rotary wheel by the stator thereby effecting peristaltic pumping.
