摘要:
An electronically controlled syringe system for connection to a balloon catheter or other balloon-type member and for automatically monitoring, displaying and recording inflation data when the syringe system is used to inflate 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 housed on the barrel of the syringe senses fluid pressure applied by the syringe. The electric signal output by the transducer 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 automatically displayed and recorded. In one embodiment, the controller is also mounted onto the syringe barrel to provide a digitally controlled inflation syringe system that is completely self-contained, and disposable.

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.

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.

This invention relates to a measuring device, which includes a body. A digital display is located in the body, the digital display being configured to show at least a linear measurement. The measuring device also includes a holding portion coupled to the body and configured to slidably engage an elongate member, such as a catheter or introducer sheath, in a space provided between the holding portion and the body. The measuring device also includes a sensor or transducer located in the body and configured to measure at least a linear distance traveled by the elongate member, such that the linear measurement is associated with the linear distance.
摘要:
A syringe apparatus for use with balloon-tipped catheters is disclosed having an attached pressure gauge and timer assembly. In one mode, the timer assembly displays the duration of a current event of inflation or deflation, and the duration of the most recent past event of inflation or deflation. In another mode, the timer assembly displays historical information showing the event number and duration of past events of inflation and deflation. The pressure gauge display and the timer assembly display are situated conveniently on the syringe assembly and in proximity to one another so as to enable a syringe operator to substantially simultaneously monitor durations of inflation and deflation without the need for an assistant, yet without requiring purchase or use of computerized monitors.

In another mode, the timer assembly can be detached from the syringe assembly at the completion of an inflation procedure and then reused with another syringe assembly. In this mode, the pressure gauge is permanently mounted to the syringe assembly, or alternatively, it is mounted to the detachable timer assembly so as to also be reusable.

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. The modular configuration of the pressure infuser apparatus permits the user to detach and reattach a motorized pump and/or a manual pump to the pressure infuser bag quickly, easily, and efficiently without decreasing the air pressure of the pressure infuser bag. By providing selectively removable pump modules, the user can select the configuration of the pressure infuser apparatus that is best adapted to the needs of the patient. A pressure release valve is configured to regulate the pressure of the pressure infuser bag.

A self-suturing anchor device includes a base having a securement mechanism. The securement mechanism includes one or more resilient pockets in which are placed a plurality of looped sutures. The securement mechanism and looped sutures facilitate automatic securement of a catheter relative to the self-suturing anchor device. In at least one embodiment, the looped sutures are also threaded through loops in another corresponding looped suture, such that each looped sutures slidably tighten in concert with one another. When at least a portion of the securement mechanism is moved, at least one of the plurality of looped sutures is tensioned and closes against a securement point on the catheter. A catheter can be secured in a self-suturing anchor device in a quick and efficient manner with minimal effort.

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.
