A self-suturing anchor device includes rotatable ring adapted to automatically deploy sutures to secure a catheter. The rotatable ring is utilized in connection with a ratchet mechanism which allows movement of the rotatable ring in a first direction while preventing movement of the rotatable ring in the opposite direction. The rotatable ring is also utilized in connection with a bearing member to facilitate smooth and efficient rotation of the rotatable ring. An extension saddle is utilized to provide a desired amount of displacement between suture securement points to minimize pivotal movement of the catheter. The rotatable ring is wider than its height to minimize kinking of the catheter tube and to relieve pressure when pressed between the patient and a support surface. In another embodiment, a plurality of scallops or other gripping members are utilized to facilitate easy gripping and rotation of the rotatable ring.

The present invention is directed to a modular pressure infuser apparatus adapted to allow a user to modify the configuration of the pressure infuser apparatus by utilizing one or more interchangeable manual and/or automatic pumps to inflate a pressure infuser bag of the pressure infuser apparatus.

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.

Monitoring and displaying pressurization data

A pressure gauge for displaying the magnitude of fluid pressure generated within a syringe or another pressurized system. The pressure gauge is removably attachable to a syringe, and may be sterilized for reuse after each medical procedure. A piezoresistive transducer senses fluid pressure and generates an electrical signal that changes in response to changes in said fluid pressure. The electrical signal is converts d to digital signals by a microprocessor. A stepper motor responds to the digital signals to control a pointer that moves across a dial to display the magnitude of the fluid pressure. A small lithium battery that can withstand high temperatures supplies electrical power to the pressure gauge. A housing unit, comprising stainless steel and a transparent window, encases the components of the pressure gauge. After use, the pressure gauge is placed in an autoclave, thereby sterilizing the pressure gauge for reuse.

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.

An electronically controlled syringe system for connection to a balloon catheter or other balloon-type member and for monitoring, displaying and optionally recording inflation or deflation data when the syringe system is used to inflate or deflate the balloon of the catheter or other balloon-type member. A syringe having a barrel and a syringe plunger is selectively operable to increase fluid pressure applied to the balloon catheter or other balloon member by sliding the plunger further into the barrel. Positive pressure applied to the balloon catheter or member is released by withdrawing the syringe plunger toward the rear of the barrel. A piezoresistive semiconductor transducer placed in fluid communication with the fluid pressure applied by the syringe, senses the fluid pressure and outputs an electrical signal representative of that pressure. The electric signal is input to a controller where the signal is digitally processed so as to derive and record therefrom electronic data representing the magnitude of applied fluid pressure, and so as also to derive the length of time that fluid pressure is applied. The electronic data representing this information is displayed and optionally recorded. In one embodiment, the electronic signal is received by a detachable and reusable electronic circuit module that detachably mounts to a housing formed on the syringe barrel.
