Medicament dosing system
First Claim
1. A medicament dosing system comprising a replaceable unit and a permanent unit, the replaceable unit comprising:
- a fluid reservoir for receiving therein a pressurizable liquid medicament;
a temperature sensor for detecting the temperature of said liquid medicament;
a fluid channel which is provided with a flow resistor and which is in flow communication with the fluid reservoir; and
a hose means which is connected to the fluid channel; and
the permanent unit comprising;
a squeezing valve means for squeezing the hose means together; and
a control means which is coupled to the temperature sensor and the squeezing valve means so as to control a flow rate of the liquid medicament by clocked actuation of said squeezing valve means depending on the temperature detected.

Abstract
A medicament dosing system comprises a replaceable unit and a permanent unit. The replaceable unit comprises a fluid reservoir for receiving therein a pressurizable liquid medicament, a temperature sensor for detecting the temperature of said liquid medicament, a fluid channel which is provided with a flow resistor and which is in flow communication with the fluid reservoir, and a hose means which is connected to the fluid channel. The permanent unit comprises a squeezing valve means for squeezing the hose means together, and a control means which is coupled to the temperature sensor and the squeezing valve means so as to control a flow rate of the liquid medicament by clocked actuation of said squeezing valve means depending on the temperature detected. Alternatively, the temperatur sensor can be arranged in the permanent unit.
