A delivery device is provided for introducing a fluid to a patient. The delivery device has a base with a bottom face for attaching to the skin of the patient, and a cannula extending from the bottom face for penetrating the skin of the patient. A fluid supply conduit has a first lumen connected to the cannula for supplying the fluid to the cannula, where the fluid contains an active agent and stabilizing agent. The conduit has a second lumen with an open end for capturing leakage of the fluid from the infusion site and carrying the fluid away from the infusion site. The second lumen has a leak detector containing a color changing in an amount to react with the stabilizing agent and produce a visual indication to the patient through the conduit. The leak detector is spaced from the infusion site and oriented in a location visible by the patient through the conduit.

A system for confirmation of fluid delivery to a patient at the clinical point of use is provided. The system includes a wearable electronic device. The wearable electronic device has a housing; at least one imaging sensor associated with the housing; a data transmission interface; a data reporting accessory for providing data to the user; a microprocessor for managing the at least one imaging sensor, the data transmission interface, and the data reporting accessory; and a program for acquiring and processing images from the at least one imaging sensor. The system further includes a fluid delivery apparatus; and one or more identification tags attached to or integrally formed with the fluid delivery apparatus. The program processes an image captured by the at least one imaging sensor to identify the one or more identification tags and acquires fluid delivery apparatus information from the one or more identification tags.

An antimicrobial light dressing device, system and method for a percutaneous treatment that bathes a treatment region around the percutaneous insertion with an antibacterial illumination source for preventing pathogens around the insertion from entering via the dermal puncture created by the insertion. The antimicrobial light dressing device combines a circumferential body centered around the insertion, and an arrangement of LEDs around the body that focus the light around the insertion and onto a therapeutic region of the insertion. An opening in the circumferential body has an articulated protrusion for offsetting a medicinal vessel such as an IV tube off the skin surface to avoid blocking light to an area under the vessel.

A single package infusion set is provided, including one or more of the following inserters: pushbutton-type, squeeze-type, contact-type, skin pinching-type, folding retraction-type, or multistage-type inserter having at least one reusable stage. The infusion set further includes adhesion means with user-selectable degrees of adhesion strength, self-sealing tube connection means, a lens feature to view, a site beneath the set, exemplary tube management and connection elements, insulin supply, adhesion concealment means, finger loops on the inserter and site preparation wipes or sprays, optionally provided as part of the inserter. The system further includes a package which may hold a number of easily released sets, retrievable by an inserter, an exemplary insertion needle handle and shroud, an exemplary squeeze-type latch between an upper portion and a lower portion of the set, and/or a tool removable upper portion of the set.

A disposable fluid flow assembly for operation in connection with a fluid pump configured to provide a flow of fluid to the disposable fluid flow assembly is provided. The disposable fluid flow assembly includes an elongated flexible tube, a needle hub connected with the flexible tube, a pressure sensor for sensing fluid pressure, and an identification circuit embedded connected with the pressure sensor. The identification is configured to provide a plurality of signals to the central controller of the fluid pump when the disposable needle assembly is connected with the fluid pump. The plurality of signals may include various signals, such as a signal to identify physical characteristics of the assembly, a signal to ensure that the assembly is authentic, a signal to ensure that the disposable assembly is not re-used, and/or a signal to ensure that the pressure signal is connected and operating properly.

An introducer needle may include a proximal end, a distal tip, and a needle lumen extending therebetween. The introducer needle may include a wall defining the needle lumen, a first notch formed through the wall, and a second notch formed through the wall. A catheter system may include a catheter adapter, a catheter extending distally from the distal end of the catheter adapter, a flash chamber coupled to the introducer needle, and the introducer needle, which may extend through the catheter. The first and second notches and the flash chamber may facilitate pressure-driven blood flow into the catheter for improved flashback and detection of transfixation when the catheter is primed prior to insertion into vasculature of a patient or otherwise.

Tissue access devices and methods of using and making the same are disclosed. The devices can have a sensor configured to occlude a flow path by deflecting a membrane into the flow path when the devices become dislodged from tissue. The sensor can be configured to partially or fully occlude the flow path. The sensor can have a spring, can be a spring, or may not have a spring. The sensor can be static or can be moved from a sensor first configuration to a sensor second configuration. The membrane can be deflected into the flow path when the sensor is in the sensor second configuration.

The present disclosure relates to a hemodialysis catheter that can monitor intravascular pressure using a MEMS sensor. The hemodialysis catheter comprises a venous lumen, an atrial lumen, and at least one MEMS system sensor. The hemodialysis catheter also comprises a data acquisition and processing system. The hemodialysis catheter can communicate with a monitor system to display pressure data.

Systems and instruments for medical procedures and methods relating thereto, such as, for example, those that can be used in minimally invasive medical procedures, among other procedures.

The present disclosure relates to an insertion type drug injection device capable of being inserted into a body for injecting a drug into a skin, including: a main body having an open insert part and formed in a tubular shape having a hollow space therein, a needle assembly formed in the insert part, provided with a plurality of needles, and including a pneumatic port and a drug injection port, and a drug injection pipe inserted into the main body and connected to a drug injection port of the needle assembly, and an air flowing pipe connected to the pneumatic port.
