  • Publication number: 20130184576
    Abstract: In a valve-equipped hand switch and a chemical liquid introduction system, a contrast medium in a syringe is delivered to a patient line through a first port, a main passage around a spacer portion, and a second port. Furthermore, a pressure (about 300 psi) of the contrast medium delivered by a chemical liquid introduction device is transmitted as a reaction force through a third plunger from a handle portion of an operation piston held by an operator. As such, the operator can directly feel the pressure of the introduced contrast medium, which gives a sense of ease to the operator during operation.

  • Publication number: 20130184575
    Abstract: A contrast liquid injector has a controller that calculates a necessary volume of the contrast medium based on a read out necessary dose of effective component per unit weight, weight of the subject, and concentration of the effective component. The injection rate of a base-operation condition is changed based on the calculated necessary volume of the contrast medium, wherein the predetermined injection time is unchanged, for all volumes of the contrast medium, when making the injection pattern, whereby a timing of an optimum concentration of the contrast medium will be substantially unchanged for all volumes of the contrast medium.

    Abstract: A pressure sensor suitable for use in a powered contrast injector system may be tested to help validate the operability and/or integrity of the sensor. In some examples, the pressure sensor may be tested by generating a pressure pulse in a fluid line fluidly connected to the pressure sensor so as to generate a first pressure reading. A high pressure fluid at a pressure above a maximum operating pressure of the pressure sensor may be conveyed through a valve fluidly connected to the pressure sensor. Subsequent to conveying the high pressure fluid through the valve, the pressure sensor may again be tested by generating a pressure pulse in the fluid line fluidly connected to the pressure sensor so as to generate a second pressure reading. In some examples, the first pressure reading is compared to the second pressure reading to determine whether the pressure sensor has passed or failed.

    Abstract: Medical apparatus and processes controllably generate medically useful micro or nano bubbles of medically desirable and controllably selectable size, size distribution, homogeneity and concentration (and/or other key bubble parameters) for patient infusion, and/or which may incorporate therapeutic or other agents for patient infusion and/or may be combined with therapeutic or other agents prior to infusion into patients. The bubble generation apparatus and processes controllably permit the adjustment and selection of key bubble parameters through bubble generation actuation and orientation techniques and through selection of bubble fluid compositions in order to facilitate medical research and/or to optimize treatment for imaging, therapy, sonoporation, inertial and non-inertial cavitation, and acoustic activation, among other medical uses. Disposable cartridges containing such bubbles are provided and may include means for patient infusion.

  • Patent number: 8308726
    Abstract: A system to minimize fluid turbulence inside a tissue cavity during endoscopic procedures. A body tissue cavity of a subject is distended by continuous flow irrigation using a solenoid operated pump on the inflow side and a positive displacement pump, such as a peristaltic pump, on the outflow side, such that the amplitude of the pressure pulsations created by the outflow positive displacement pump inside the said tissue cavity is substantially dampened to almost negligible levels. The present invention also provides a method for accurately determining the rate of fluid loss into the subject's body system during any endoscopic procedure without utilizing any deficit weight or fluid volume calculation, the same being accomplished by using two fluid flow rate sensors. The present invention also provides a system of creating and maintaining any desired pressure in a body tissue cavity for any desired cavity outflow rate.

  • Publication number: 20120283561
    Abstract: A contrast media injection system includes detects the absolute position of the syringe ram using a non-contact sensor. A series of magnets and Hall-Effect sensors may be used or an opto-reflective system. Illuminated knobs that are connected to the drive mechanism for the syringe ram rotate with the drive and provide visual feedback on operation through the illumination. Analog Hall-Effect sensors are used to determine the presence or absence of magnets that identify the type of faceplate being used. The faceplates include control electronics, connected to the powerhead through connectors, which may be interchangeably used by the two faceplates. The faceplate electronics include detectors for automatically detecting the capacity of pre-filled syringes.

  • Patent number: 8265733
    Abstract: To facilitate imaging of a patient two different image recording methods are to be carried out at the same time. An auxiliary fluid, for example a contrast medium or a tracer, may be introduced into the body in each image recording method. The invention proposes mixing the two auxiliary fluids in situ immediately before dispensing to the patient. For this purpose it provides an injector with which the auxiliary fluids may be mixed and supplied to the patient. Devices for controlling dispensing of fluid from containers connected to the injector to produce a mixed solution may be electronically controlled by a control unit which calculates the total quantities, and optionally sub-quantities, of auxiliary fluids, which are used for a mixed solution, before activating the devices.

    Abstract: A bladder syringe for a fluid delivery system includes a cylindrical body, a cap-bladder assembly, a plunger element disposed in the cylindrical body, and a mounting assembly to secure the cap-bladder assembly to the cylindrical body. The cylindrical body has a distal end and a proximal end and defines a throughbore. The cap-bladder assembly is adapted for connection to the distal end of the cylindrical body, and includes a cap body and a bladder. The cap body defines an interior cavity and a distal discharge conduit and is adapted to engage the distal end of the cylindrical body. A disc-shaped bladder is disposed within the interior cavity and typically includes a central membrane portion. The plunger element is disposed in the throughbore of the cylindrical body and is vented to enable evacuation of the space between the plunger element and the cap-bladder assembly in the cylindrical body.

  • Publication number: 20120143053
    Abstract: A hand-held remote for a medical fluid injector includes a syringe and a conduit which may be coupled to a pressure transducer on a control circuit of the injector. Movement of a plunger within a syringe body on the syringe creates a pressure which is sensed by the pressure transducer and the control circuit responds to the sensed pressure by causing fluid to be ejected from, or drawn into, a syringe mounted to the injector. The pressure developed by the remote provides tactile feedback to an operator for improved control over injections.
