An intravenous delivery system may operate by gravity feed, and may have a liquid source containing a liquid, a drip unit that receives the liquid from the liquid source, and tubing that receives the liquid from the drip unit for delivery to a patient. A flow rate sensor may be used to measure a flow rate of liquid through the intravenous delivery system, and may generate a flow rate signal indicative of the flow rate. A controller may receive the signal, and may compare the flow rate with a desired flow rate. If the flow rate is more or less than the desired flow rate, the controller may transmit a control signal to a flow rate regulator. The flow rate regulator may receive the control signal and, in response, modify the flow rate to bring the flow rate closer to the desired flow rate.

IV flow management systems and methods

A catheter system may include a catheter adapter and a wing extending outwardly from the catheter adapter. The wing may include a groove or slot. The catheter system may include a needle hub and a paddle extending outwardly from the needle hub. The paddle may include an extension disposed within the groove or the slot to reduce axial movement between the catheter adapter and the needle hub, which may be advantageous during insertion of the catheter system into a patient. The extension may be removable from the groove or the slot to allow axial movement between the catheter adapter and the needle hub during removal of the needle hub from the catheter adapter, for example. The paddle and/or the wing may include a shape to reduce axial movement between the catheter adapter and the needle hub, which may also be advantageous during insertion of the catheter system.

Providing resistance to separation of a catheter adapter and a needle hub

A catheter system may include a catheter adapter, which may include a body and a nose extending distally from the body. The nose may be generally cylindrical. A strain relief rib may be disposed on the nose. The strain relief rib may be constructed of a flexible material. A bump may be disposed on the strain relief rib and configured to contact a needle cover. A catheter may be secured within the catheter adapter and extend distally beyond the nose.

Needle cover retention

An IV catheter system may have a catheter component and a needle component. The catheter component may have a catheter hub, a cannula extending distally from the catheter hub, and a push feature extending outward from the catheter hub. The push feature may have an outer surface that receives contact from a digit to move the IV catheter system from an insertion configuration, in which the needle is within the cannula, to a fluid delivery configuration, in which the needle is outside the catheter hub. The needle component may have a needle hub and a needle extending distally from the needle hub along an axis. The push feature may be formed of a flexible material that causes the push feature, in response to pressure exerted on the outer surface by a dressing securing the catheter component to a patient, to deflect the outer surface toward the cannula axis.

Soft push tabs for catheter adapter

An IV catheter system may have a catheter component with a catheter hub, a cannula extending distally from the catheter hub, and a push feature protruding outwardly from the catheter hub. The IV catheter system may also have a needle component with a needle hub, a needle extending distally from the needle hub along an axis, and a grip extending from the needle hub, generally parallel to the axis, with a pull feature. In the insertion configuration, the needle may be positioned within the cannula and the distal end of the needle hub may be seated in a needle port of the catheter hub. In the fluid delivery configuration, the needle may be positioned outside the catheter hub. The push and pull features may be positioned to facilitate manipulation with a single hand to move the IV catheter system from an insertion configuration to a fluid delivery configuration.

Ergonomic IV systems and methods

A catheter system may include a catheter hub, a septum disposed within the catheter hub, a catheter tube extending from the catheter hub, a needle hub, and an introducer needle secured within the needle hub. The catheter hub may include a push tab and one or more ribs, which may extend outwardly from an upper surface of the catheter hub. The ribs may be shorter in height than the push tab and/or may be generally parallel to the push tab. The introducer needle may include a flashback notch. In response to insertion of the introducer needle into vasculature, blood may flow into the introducer needle, through the flashback notch, and into a flashback chamber disposed between the septum and the catheter tube. The flashback chamber may be disposed distal to the push tab and the ribs, which may improve visualization of the flashback chamber by a user.

Medical device with anti-rotation push tab

A catheter device to visually identify a blood vessel may include a cannula. The cannula may include a distal tip, an elongated tubular shaft, and an inner lumen formed by the elongated tubular shaft. The cannula may also include an optical fiber, which may be disposed within the inner lumen of the cannula. The optical fiber may include a distal end and a proximal end. The optical fiber may be configured to emit light from the distal end.

Cannula with light-emitting optical fiber

An intraosseous access device can include a constant-torque spring assembly disposed in a housing, a drive shaft extending from the housing, and an intraosseous needle coupled to the drive shaft configured to provide intraosseous access to a medullary cavity of a patient. A method of using an intraosseous access device can include inserting a distal end of the intraosseous needle through skin at an insertion site of a patient and applying a contacting force to a bone beneath the insertion site with the distal end of the intraosseous needle. The contacting force can initiate a winding of a metal ribbon of the constant-torque spring assembly from an output spool onto a storage spool, thereby initiating drilling rotation of the intraosseous needle. The method can further include drilling through the bone until the intraosseous needle enters a medullary cavity of the patient.

Constant-torque intraosseous access devices and methods thereof

A pinch clamp for use in occluding intravenous tubing or other similar tubing can include patient comfort features and/or lateral disengagement prevention features. These features can also be designed in a manner that allows the pinch clamps to be more easily manufactured. A pinch clamp can include a first arm that is coupled to a second arm by hinges. Each of the first and second arms can form a clamping surface that are aligned when the first arm is positioned overtop the second arm. The first arm can include opposing openings and the second arm can include opposing tabs which insert through the openings when the first arm is positioned overtop the second arm. The retaining tabs interface with the openings to prevent the first arm from separating from the second arm.

Pinch clamp

Devices and methods for an autovance intraosseous device. The autovance intraosseous device can include a trigger activated system or pressure activated system that causes a needle to advance distally for a predetermined distance. The predetermined distance ensures a needle tip extends through the bone cortex, to access the medullary cavity, without penetrating a far wall of the medullary cavity. The advancement can be driven by a spring based system or an electric motor.

Autovance feature of an intraosseous device

Pinch clamps are provided which generate positive displacement while also preventing rebound. To prevent rebound while providing positive displacement, the upper and lower clamping surfaces may be configured to form a pinch profile along which the tubing is compressed with the pinch point being formed at the distal end of the pinch profile. To further prevent rebound, the lower arm of the pinch clamp can include blocking ribs that interface with the upper clamping surface to prevent distal travelling of the pinch point even if the upper arm is forced into an over-engaged position.

A needle stick prevention device () includes a needle shield () for selectively covering a distal end of a needle (). A needle hub () is movably received within the needle shield (). The needle hub () includes a proximal end (), a distal end (), a needle () fixedly connected to the distal end of the needle hub (), and a plurality of ribs () or a cylinder () disposed between the proximal and distal ends. An actuation button movably received in a transverse opening of the needle shield () to engage the needle shield (), the needle hub () and a medical device. A spring () is disposed between the needle hub () and actuation member to automatically retract the needle () into the needle shield ().

Catheter systems comprising independent fluid paths are disclosed. The catheter systems can include a catheter adapter that has a catheter hub with a chamber. A catheter extends from a distal end of the catheter hub and is in fluid communication with the chamber. A stabilization platform with a first wing and a soft push tab are also part of the catheter hub. The catheter system includes a needle hub with a needle that slidably fits within the catheter. In an insertion configuration, a proximal extension of the catheter hub is removably coupled within a distal opening of the needle hub. After the catheter is placed, the needle hub is retracted from the catheter adapter to slidably remove the needle from the catheter.

Integrated catheter with independent fluid paths

A needle hub including a core mounting structure, a first panel and a second panel each connected to the core mounting structure with an opening formed between the first panel and the second panel, and an introducer needle fixedly attached to the core mounting structure; a first actuation lever disposed within the opening, cantilevered at a central portion thereof from the core mounting structure that has a first actuation button disposed at a proximal free end and a first needle hub latch disposed at a distal free end. A needle tip shield is rotatably connected to one of the first panel and the second panel and rotatable from a first position in which a distal end of the introducer needle is exposed to a second position shielding the distal end of the introducer needle.
