Mobile fluid delivery system with detachable pedestal

Abstract

The mobile fluid delivery system includes a mobile pedestal and a fluid delivery superstructure detachably connected to the pedestal. The fluid delivery superstructure includes a pump device and a fluid control device. A fluid path set operatively associates the pump device with the fluid control device. The superstructure is further adapted to detachably connect to a patient examination platform. A rail mount is used to provide the interface between the superstructure and the patient examination platform. The rail mount attaches to a rail of the patient examination platform and includes a main body defining an elongated recess for engaging the rail of the patient examination platform. The superstructure detachably connects to the main body. Locking devices are used to secure the rail mount to the patient examination platform and the superstructure to the rail mount. A spacer may be inserted into the elongated recess to accommodate different sized rails.

AI Technical Summary

Benefits of technology

[0020] In one aspect, the manual control includes a first actuator providing control of flow rate of the first fluid by changing the force on the first actuator and a second actuator, the second actuator causing the injector to enter into a preprogrammed high pressure injection mode when placed in an on state. The system may further include a pressure sensor in fluid communication with the second fluid path via a pressure-activated isolator that isolates the pressure sensor from pressures in the second fluid path above a set pressure. In one embodiment, the per-patient disposable section may include a check valve in the second fluid path separating components of the per-patient disposable section from the multi-patient reusable section to reduce or eliminate flow of contaminated fluid into the multi-patient reusable section.

[0076] Furthermore, the pump device may be a syringe, and the method may include actuating the fluid control device to isolate the syringe from the source of injection fluid and the patient, and retracting a syringe plunger in the syringe to reduce fluid pressure in the syringe.

Problems solved by technology

Manual sources of fluid pressure and flow used in medical applications such as syringes and manifolds thus typically require operator effort that provides feedback of the fluid pressure / flow generated to the operator.

The feedback is desirable, but the operator effort often leads to fatigue.

However, compliance in the system components, for example, expansion of the syringe, tubing, and other components under pressure, using such a manifold system can lead to a less than optimal injection bolus.

Moreover, the arrangement of the system components of U.S. Pat. No. 5,800,397 results in relatively large amounts of wasted contrast and / or undesirable injection of an excessive amount of contrast when the low pressure, typical saline system, is used.

Unlike manual injection systems, however, there is little if any feedback to the operator of system pressure in the systems disclosed in the U.S. Patents identified previously.
