IV Extravasation Detection Device

A fluid extravasation detection device detects the subcutaneous extravasation of fluid from a vein containing an intravenous (IV) catheter. The device includes one or more first temperature sensors for positioning on skin near an entry point of the IV catheter into the vein, and one or more second temperature sensors for positioning on skin near a tip of the subcutaneously located IV catheter. The first and second temperature sensors are operably connected to an electronic thermometer that compares the temperature difference between a first temperature and a second temperature. The first temperature is determined based on temperature detected by at least one of the one or more first temperature sensors. The second temperature is determined based on temperature detected by at least one of the one or more second temperature sensors. An alarm is activated if the difference between the first and second temperatures changes more than a predetermined amount.

SELF-ACTIVATING CATHETER INSERTION SITE DRESSING
20210228765 · 2021-07-29 ·

A self-activating dressing for use with a medical device inserted into a skin surface of a patient via a skin insertion site. The dressing includes a dressing body impregnated with a nitric oxide releasing compound which reacts in the presence of a physiological fluid to release nitric oxide. Nitric oxide provides antimicrobial activity and promotes wound healing. The nitric oxide releasing compound may include s-nitroso-n-acetyl penicillamine (SNAP), s-nitrosoglutathione (GSNO), and mixtures thereof. A slit defined in the dressing body enables the dressing body to be placed around a perimeter of the medical device on the skin surface at the skin insertion site such that the dressing body surrounds and contacts skin insertion site. The dressing body may be further impregnated with a catalyst, such as copper, iron, zinc, selenium, and silver, to facilitate release of nitric oxide. The dressing body may be further impregnated with an additional antimicrobial agent.

Catheter anchor system and method thereof

A method and system of and for securing a lumen or catheter, after placement in a patient, to prevent unwanted removal or dislodgement of the lumen or catheter caused by patient movement and/or further medical interventions such as cardiopulmonary chest compressions, electrical defibrillation, surgical procedures, and the like. The method and system comprising simple and sterile materials that preclude the use of excessive suturing and ineffective ad-hoc methods with tape and gauze. The catheter is secured by a rubber on plastic frictional force and will resist external forces while preventing the tube structure from bending and subsequent occlusion. The device can be comfortably attached to the patient in all of the anatomical locations typically targeted for large catheter installment. The method of securement is rapid and requires only a single personnel to handle the device and the catheter tube simultaneously.

Method and Apparatus for a Perforable Absorbent Portion Bandage (PAP-B) for Avoidance of Constant Adhesive Removal
20210177664 · 2021-06-17 ·

An apparatus for removing a dressing without removing an adhesive portion comprising: an absorbent central portion; an adhesive frame; the absorbent portion coupled to the adhesive frame by a perforated border; and the perforated border with a tab, whereby a user holds the tab and pulls in any one of a direction to loosen free the absorbent portion from the adhesive frame via the perforated border, thereby freeing the absorbent portion from an applied skin surface without a need for removing the adhesive frame from the applied skin surface for mitigating against a risk of MARSI, tube dislodgement, or any risk associated with constant adhesive tape removal from a skin surface during long-term wound or tube insertion dressing.

WINDOW DRESSING FOR USE WITH ULTRASONIC AID IN VENIPUNCTURE
20210177456 · 2021-06-17 ·

A window dressing includes a primary layer having a window for viewing a catheter insertion site. The primary layer includes an adhesive layer on a lower, skin-contacting face of the primary layer. A transparent layer covers the window and adheres to the upper surface of the primary layer. An ultrasonic transmission layer is positioned below the primary layer, where the transmission layer comprises a layer of hydrogel. A support structure has a stiffness that is greater than the primary layer and has an adhesive layer on the lower surface of the support structure. The support structure adhesive layer adheres the support structure to the upper surface of the primary layer.

Catheter connection and stabilization device and methods of using same

A device for stabilizing a patient catheter includes a docking pod with a body, an inlet, an outlet, an internal fluid path between the inlet and the outlet, and a securement surface located on an underside of the docking pod. A docking pod adhesive layer located at least partially on the securement surface of the docking pod may secure the docking pod to the patient such that the securement surface and the docking pod adhesive layer form a generally planar or concave surface when secured to the patient. A valve mechanism located within the internal fluid path of the docking pod may control fluid flow through the docking pod. The device may also have a luer connector that is fluidly connected to the outlet of the docking pod and configured to be connected to the catheter.

Catheter positioning device
20210146097 · 2021-05-20 ·

The invention provides a catheter positioning device which comprises a base fixed on a body, a positioning guide groove arranged on the base, and a self-locking module positioned on two opposite sides or one side of the positioning guide groove, wherein when the catheter is positioned at a preset position in the positioning guide groove, the self-locking module is in a released state; and when the catheter moves relative to the positioning guide groove to deviate from the preset position, the self-locking module is triggered to switch from the released state to a locking state, so that the self-locking module in locking state limits the movement of the catheter relative to the positioning guide groove so as to achieve the technical effect of positioning the catheter.

INTEGRATED VASCULAR ACCESS DEVICE AND ANCHOR PAD
20210106786 · 2021-04-15 ·

An anchor system for securing a vascular access device to a patient may include an anchor pad, which may include a lower surface, an upper surface, and a window extending through the anchor pad. The system may also include the vascular access device, which may include a body and a stabilization platform extending from the body. The anchor pad may be coupled to and extend distally from the stabilization platform.

Catheter securement device with window

An anchor system for securing a catheter to a patient may include an anchor pad, which may include a lower surface, an upper surface, and a window extending through the anchor pad. The lower surface may include an adhesive layer to adhere the anchor pad to skin of the patient. The upper surface may include a catheter securement mechanism. The window may provide access to the skin of the patient for application of a topical skin adhesive at a catheter insertion site disposed within the window.

SYSTEMS AND METHODS FOR SECURING CATHETERS
