Abstract
A low-cost medical pump for ambulatory use provides reduced life components combined with a pump lockout enforcing a safe operating limit and preventing reuse after that limit is exceeded. An improved IV line clamp portion minimizes unsupported clamp structure length and provides a dual lock system preventing inadvertent clamp release.
Claims18
A medical tube assembly detachable from a pump housing holding outwardly extending peristaltic actuator elements, comprising:
- a flexible medical tube adapted to communicate between an external fluid bag and a patient connection;
- and
- a substantially rigid frame having first and second opposed longitudinal walls extending along a longitudinal axis of the frame defined by a longest dimension of the frame and separated by first and second opposed end walls and retaining the medical tube against movement therein wherein the medical tube extends along the longitudinal axis of the frame, the frame including a connector detachably attaching the frame to the pump housing and medical tube guides to align the medical tube along the longitudinal axis of the frame and with the peristaltic actuator elements to permit peristaltic pumping of liquid of the medical tube when the frame is attached to the pump housing;
- wherein the connector provides a first attachment element including a first hinge portion extending and positioned along one of the first and second opposed longitudinal walls of the frame and to releasably attach to a second hinge portion of the pump housing wherein the first hinge portion is attachable to the second hinge portion to thereby pivot about a hinge axis extended along the longitudinal axis of the frame;
- wherein the connector provides a second attachment element including receiving tabs extending along the other of the first and second opposed longitudinal walls of the frame and to releasably receive corresponding hooks of the pump housing by movement of the corresponding hooks generally along the pump housing and the other of the first and second longitudinal walls of the frame;
- wherein the medical tube is comprised of a first material positioned outside of the frame and a second material softer than the first material, the softer material positioned between the opposed first and second ends of the frame.
