    摘要： A system and method for electronically monitoring and displaying digital flow data relevant to the administration of a parenteral fluid, such as a contrast medium, to a patient is disclosed. The system includes a disposable fluid flow indicator, adapted to be detachably connected in fluid communication with a contrast media source. The fluid flow indicator measures the amount of contrast media dispensed from the source and administered to a patient, and provides an indication of the amount dispensed based on the movement of a displacement indicator. Also disclosed is an electronic controller, which is adapted to be detachably connected to the fluid flow indicator. The controller includes a sensor interface circuit, which operably interfaces the electronic controller circuitry with the fluid flow indicator so that the fluid flow measurement indicator is optically detected by the sensor circuit, which in turn generates a representative electrical flow signal. The electrical flow signal is received and processed by a programmable digital processor contained within the electronic controller in a manner so as to continuously track and generate digital flow data. The digital flow data includes information regarding the amount of contrast medium remaining within the contrast source, and the amount of medium that has been delivered to the patient. The electronic controller also includes a digital display, which continuously displays the digital flow data. The controller also includes a series of user actuable switches, which permit the user to select various functions to be performed by the digital processor, including the ability to display digital flow data for prior patients, and the ability to select various operating parameters. Since the electronic controller is detachably connected to the flow indicator, the controller can be reused at the completion of a monitoring procedure. Also disclosed is a method for safely and efficiently monitoring and displaying the amount of contrast medium administered to a patient by using a programmable digital processor.

    摘要： The present invention relates to a system for irrigating a wound with wound irrigation fluid and for preventing substantial splashback of the wound irrigation fluid. The system comprises: (i) fluid delivery device for delivering wound irrigation fluid; and (ii) a flexible wound irrigation shield configured such that the shield prevents substantial splashback of the irrigation fluid upon irrigation of a wound. The shield is configured to be disposed, preferably removably, on the fluid delivery device. The flexible shield is substantially conformable to a desired wound area, enabling the practitioner to irrigate awkward, uneven, and hard to reach areas. The shield can be folded into a compact position, then opened into a larger shield. The fluid delivery device comprises (i) a fluid source for providing wound irrigation fluid; and (ii) an adaptor for transmitting fluid from the fluid source to the wound. In one embodiment, the adaptor has a substantially planar face that is substantially coplanar with the plane defined by the shield, thereby preventing patient puncture. The preferred adaptor, preferably a multi-part adaptor, features spray pattern adjustability, removable coupling to the shield, the capacity for removably coupling to a variety of different fluid sources, and a variety of other features and advantages.

    摘要： Methods and systems for controlling and monitoring pressurization data. The methods and systems advance beyond the prior art in their ability to convey pressurization data unambiguously. The methods and systems include a novel combination of visual cues and control features to insure that pressurization data may be analyzed accurately. For example, the visual cues and control features include changing the background color of the display area and providing a pressurization arrow to indicate pressurization or depressurization; a time showing the elapsed time of pressurization or depressurization; a pressurization number indicating the number of pressurization cycles that have occurred; software keys for making configuration choices; and text and graphic display modes. A touch interface may be provide for user interaction. To insure accurate pressure measurements, at least one pressure reference standard may also be utilized.

    摘要： A novel catheter apparatus for use in delivering an anesthetic agent or other fluid medicament to the portion of subcutaneous tissue through which a catheter device has been inserted into a patient, thereby allowing the catheter device to be further manipulated or retracted without causing pain or discomfort to the patient. The catheter device has an indwelling cannula adapted for insertion through subcutaneous tissue into a patient's body. A cylindrical sleeve around the cannula can be positioned within the subcutaneous tissue once the cannula has been inserted into the body. The cylindrical sleeve has formed therein one or more lumens into which the anesthetic agent or other fluid medicament can be delivered via a hub that is connected to the proximal end of the cylindrical sleeve. The cylindrical sleeve has formed therein a plurality of delivery holes that form a fluid communication path with the one or more lumens. The delivery holes permit the anesthetic agent or fluid medicament to be delivered to the surrounding subcutaneous tissue.

    摘要： An electronically controlled syringe system for connection to a balloon catheter for automatically monitoring, displaying and recording inflation or deflation data. A syringe applies and releases pressure to and from the balloon catheter. A transducer housed on the syringe barrel emits at atmospheric pressure a signal by which both the syringe and transducer are recognizable to the system as a particular type of syringe. The system prompts the user to verify the recognized type of syringe. The system prompts the user to verify the recognized type of syringe. The transducer, which can be calibrated, senses fluid pressures applied by the syringe. The signal output by the transducer is input to a controller where the signal is digitally processed so as to derive and record therefrom data representing the magnitude of applied fluid pressure and the length of time that pressure is applied by the syringe. The data is automatically displayed and recorded. The syringe system permits input of various control parameters, such as a maximum positive inflation pressure and maximum duration for applying pressure.

    摘要： A novel catheter apparatus for use in delivering an anesthetic agent or other fluid medicament to the portion of subcutaneous tissue through which a catheter device has been inserted into a patient, thereby allowing the catheter device to be retracted without causing pain or discomfort to the patient. The catheter device has an indwelling cannula adapted for insertion through subcutaneous tissue into a patient's body. A cylindrical sheath is placed on the cannula so as to be positioned within the subcutaneous tissue once the cannula has been inserted into the body. The cylindrical sheath has formed therein a lumen into which the anesthetic agent or other fluid medicament can be delivered via a hub that is disposed on the catheter apparatus. The cylindrical sheath has formed therein a plurality of one-way slit valves. The one-way slit valves permit the anesthetic agent or fluid medicament to be delivered to the surrounding subcutaneous tissue, and also prevent any bodily fluids from entering the lumen. In one embodiment the cylindrical sheath is permanently mounted to the cannula. In another embodiment the cylindrical sheath is detachably mountable to the cannula. In yet another embodiment, the lumen is formed within the outer wall of the cannula and the one-way slits are formed through the outer wall.
