Embodiment Construction

[0058] figure 1 An infusion pump 1 is schematically shown. The infusion pump 1 includes an infusion body 2 and a cap 3 . The cap 3 is provided with locking features 9, such as bayonets, screws, snaps or the like, to connect the cap 3 to the body 2 of the infusion pump 1 . The main body 2 of the infusion pump 1 is provided with corresponding locking features 10, such as Figure 5 bayonet, screw, snap or similar shown in . The infusion body 2 and cap 3 are configured to retain the fluid container 4 in the cavity volume 11 within the body 2 of the infusion pump 1 .

[0059] image 3 and Figure 4 An embodiment of a fluid container 4 is shown. image 3 and Figure 4 The fluid container 4 comprises a cylindrical body 4 a and a piston arrangement comprising a seal support 6 and a seal 7 . The seal support 6 and seal / piston 7 enable the introduction of medicament fluid 8 into the container 4 and may be fitted to the handle 5 for moving the piston arrangement. Furthermore, th...

Abstract

An infusion pump for administering controlled doses of fluid comprises a pump body 2 and cap 3 attachable to the pump body 2 to retain a medicament fluid receptacle 4 in the pump body 2, The fluid receptacle 4 is connected to a tube 12 for dispensing the fluid. The tube 12 is directed through a normally closed valve within the cap 3. The pump body 2 comprises a propulsion device engaging with a piston support 6 of the fluid receptacle 4, coupled to a retaining member, a drive system coupled to the retaining member and a rigid member coupled to the drive system. Actuation of the drive system enables the propulsion device to deliver fluid. In addition, the rigid member moveably projects into the cap to open the normally closed valve to allow the passage of fluid.

Description

technical field [0001] The present invention relates to an infusion pump for administering controlled doses of fluids, and in particular to an ambulatory infusion pump for administering medicament fluids to a patient. Infusion pumps include means for ensuring efficient delivery of medicament fluids and means for ensuring safe use of the infusion pump in case of breakage and in case of incorrect use. [0002] Infusion of a controlled flow or volume of medicament fluid over a controlled and often prolonged period of time is advantageous for many treatments when the body must receive gradual amounts of the medicament rather than doses in a single event. They can also be beneficial when the flow of medicament fluid increases or decreases in response to observed or measured patient conditions. Such an infusion pump can be connected to a patient for a substantial period of time when the patient may be healthy and mobile, and thus the ambulatory nature of the infusion pump provides ...
