Embodiment Construction

[0014] Referring now to the drawings, FIG. 1 is a schematic diagram of an exemplary perfusion pump in accordance with an embodiment of the present invention. The irrigation pump 10 includes a keypad assembly 20 attached to the pump housing 15 to form an airtight seal. As used herein, "hermetically sealed" or "hermetically sealed" means that the relationship between the keypad assembly 20 and the pump housing 15 is formed so as to be impermeable to gases and other fluids. The electronic components secured between the keypad assembly 20 and the pump housing 15, such as the flex circuit disposed on the flex circuit board, are thus shielded from the ingress of air and moisture, thereby maintaining the safety of the circuitry on the flex circuit and quality and operation of the perfusion pump.

[0015] FIG. 2 shows the irrigation pump 10 of FIG. 1 with the keypad assembly 20 removed from the pump housing 15 to expose the keypad assembly area 25 . Keymat assembly area 25 is sized ...

Abstract

According to the present invention there is provided an infusion pump and a method of manufacturing the same. The priming pump includes a pump housing formed from a first material and defining a keypad assembly area. Disposed within the area of ​​the keypad assembly and electrically connected to the priming pump is a flexible circuit. The keymat assembly is hermetically sealed in the area of ​​the keymat assembly over the flexible loop. The keypad assembly includes a frame made of a second material and defining a perimeter dimensioned to cooperate with the keypad assembly area, the frame having an adhesive surface and an overmolding surface, and a cover made of a third material and attached to the frame. Keypads in direct contact with molded surfaces.

Description

technical field [0001] The present invention is directed to an infusion pump, and more particularly, an infusion pump having a silicone keypad overmolded on a frame chemically bonded to the pump housing forming an air gap between the keypad assembly and the pump housing. Tight seal. Background technique [0002] In general, medical patients sometimes require accurate continuous delivery of medication or delivery of medication at set periodic intervals. Pharmaceutical infusion pumps have been developed to provide controlled infusions of drugs, where drugs are dispensed at precise rates, maintaining drug concentrations within therapeutically safe limits. Basically, drug infusion pumps provide proper drug delivery to the patient at a controlled rate so that constant attention is not required. [0003] Certain infusion pumps are designed to be controlled by the patient via a user interface. These patient-controlled pumps based on perfusion needs allow the user to manipulate c...
