Problems solved by technology

Rough handling or extreme overloading is a concern especially in the latter case, as the sensor may be irreparably damaged, requiring the pump to be taken out of service for repair

Embodiment Construction

[0016] With reference to the accompanying drawings, figure 1 An example of a medicament syringe pump 10 comprising an overload protection device 12 according to the inventive subject matter is depicted. The medicament syringe 14 is depicted in an operative position, mounted near the top of the syringe pump 10 .

[0017] Syringe pump 10 includes base 16 , display and user input panel 18 , handle 20 , and plunger driver 22 . The plunger driver 22 includes a drive rod 23 and a syringe engaging head 24 . The syringe 14 is removably received by the syringe pump 10 in a syringe carriage 26 formed near the top of the syringe pump 10 . Syringe clamp 28 is used to hold syringe 14 in place on syringe pump 10 . The syringe 14 includes a syringe barrel 30 and a syringe plunger 32 . The syringe plunger 32 includes a thumb press 34 at the distal end. Plunger drive 22 may be actuated by an electric drive motor (not shown) of pump 10 .

[0018] refer to figure 2 , the overload protect...

Abstract

An overload protection method and apparatus for a medicament syringe pump force sensor. A dome switch is employed with force sensor components of a medicament pump. The dome switch collapses at overload pressures, isolating the force sensor from pump driving forces that exceed the force sensor limit. An alarm signal can be triggered by the overload, and initiate pump shut down.

Description

technical field [0001] Embodiments relate to a medicament infusion pump. In particular, embodiments relate to a method and apparatus for sensing and preventing force overload in a drive mechanism of a syringe pump used to administer a medicament to a patient. Background technique [0002] Syringe pumps are used in a variety of therapeutic areas to administer drugs, nutritional ingredients, and prescribed fluids or fluid-like substances (collectively "medications") to patients in doses that are controlled in volume and time. Agents can be administered precisely and continuously by such pumps at infusion rates typically ranging from as low as 0.1 ml / hr to as high as 1200 ml / hr. Syringe pumps are well suited for applications such as pain control and palliative care and are also frequently used in neonatal and pediatric intensive care units due to their ability to deliver medication in a precise, accurate and continuous manner. [0003] In operation, a medicament syringe pump ...
