A vascular compression apparatus and method for applying pressure onto an area of a patient generally including a blood vessel and a wound site, such as a blood vessel puncture, after a cannulated procedure for the purpose of controlling bleeding and achieving hemostasis. The vascular compression apparatus includes a handle, a shaft and a pad. The shaft extends generally downward from the center of the bottom side of the handle. The pad is connected generally off-center of its top side to the bottom end of the shaft. The bottom side of the pad is convex to allow the vascular compression device to be rocked back and forth. In use, the pad is generally placed proximal to the catheter insertion site and over the blood vessel containing the catheter. The device is rocked proximally to control blood flow while removing the catheter. After the catheter is removed from the puncture site, the device is rocked distally to the puncture site, where pressure is applied until hemostasis is achieved.

A method of inserting a catheter into a body of a patient includes identifying a catheter insertion site on the patient's body; measuring a length, from the insertion site to another site external to the body of the patient, and along an external path that follows a presumed internal path of the catheter from the insertion site to a target site within the patient's body, using an automatic measuring device; trimming the catheter to an appropriate length based on the length measured by the automatic measuring device; and inserting the trimmed catheter into the body of the patient through the insertion site to the target site.

This application describes example antimicrobial compositions that may be used alone or in combination with catheters and catheter insertion sites. According to another aspect, the application describes catheters which may employ one or more protection devices, such as cleaning caps, protective caps or both.

A hydrogel dressing for covering or treating a wound, a surgical incision, a catheter insertion site or the like, comprising a non-fluid sheet material including a structure of cross-linked polymers and / or monomers having suspended therein an agent for controlling infection of the wound, the incision, the catheter insertion site or the like.

The invention refers to a stabilization device for attaching and securing a catheter to the skin of a patient in order to maintain the catheter correctly placed through a catheter insertion site. The stabilization device includes a catheter clipping element which is attached to an anti-allergic adhesive pad. The catheter clipping element includes a clipping body that ends in open arms for easy and convenient clipping and unclipping of a catheter, cannula, catheter or cannula terminal adapter, or the like. The clipping body is oriented outwards from the top surface of the pad in a transverse direction, a vertical direction, or both transversely and vertically, in order to facilitate clipping and unclipping. A longitudinal axis of the clipping body can be tilted towards the pad top surface in order to enhance stabilization and favor correct orientation of the catheter towards the insertion site.

Devices and methods are provided for inserting a sterile catheter, and for maintaining a sterilely sealed catheter and catheter insertion site over time. In one embodiment, a four-part integrated system is provided that includes (1) a novel vascular catheter with integrated uniform diameter mounting, capping, and needle safety procurement features; (2) a novel vascular catheter dressing designed to specifically mate with and seal to this vascular catheter to achieve a sterile seal both at the catheter-skin insertion site and the catheter-dressing exit site; (3) a hub protection and sterilizing apparatus that serves to stabilize, protect, and sterilize the working end of the catheter hub as it protrudes from the sterile dressing, and that also helps to improve the ergonomics of the catheter-dressing complex in order to avoid snagging on clothing etc.; and (4) a whole dressing accessory secondary cover and securement device. Together, the components of this system work in a novel fashion to achieve a sterile, sealed, and fully secure vascular access site. While each of the four components can work together as part of an integrated system, each component can also be utilized individually, in any combination, or in conjunction with existing dressing-catheter technologies.

A catheter and dressing assembly is disclosed including a dressing having a distal adhesive plate configured for attachment to a skin region surrounding a catheter insertion site to provide a first circumferential seal around the catheter at the insertion site, a dressing body extending from the adhesive plate and configured to surround a catheter segment external to the insertion site and a proximal sealing element. The assembly further includes a two-part catheter having a first distal part consisting of a hub base bonded to a tubular catheter body; and a second proximal interconnector-cap that is adapted to couple to the distal hub base, whereby the attachment of the interconnector-cap to the hub-tubular body portion of the catheter establishes at least one continuous fluid pathway extending from a proximal end of the interconnector-cap to a lumen of the catheter and wherein either the hub base or the interconnector cap further comprises a mating feature for mating to the proximal sealing element of the dressing such that the dressing and interconnector-cap provide a second circumferential seal around the catheter body.

The device disclosed herein may be affixed over a transparent dressing overlying the catheter entry point, or may be used independent of such a dressing. The device may be affixed to the catheter insertion site using an adhesive or fastening band, or through other methods. Depending on context, the device may be used continuously or periodically, and may be affixed such that it is directly abutting a transparent dressing or directly adjacent to the skin surface, or it may be spaced a certain distance from the skin. If spaced from the skin, light may be directed from the light sources, either directly or indirectly through optical conduits. Preferably the light sources will be positioned such that light from the light sources overlaps at one or more areas on the skin, especially the catheter entry point.

Devices and methods are provided for sealing a catheter insertion site to maintain sterility. In one aspect of the invention, mounting handle / dressing assemblies and kits are disclosed for creating a sterile sealed environment around a catheter insertion site. For example the dressings of the present invention can be pre-disposed around a mounting handle and connector. The connector is joined to the proximal end of the catheter and then the dressing can be slid along the mounting handle until it surrounds the insertion site. Once the dressing is adhesively applied to the skin and locked into place by an annular fitting between the dressing and the connector, the handle can be removed and discarded, leaving only the dressing, and catheter connector in place. The catheter connector preferably has a needle-free connector port at its proximal end for connection to IV lines or other infusion devices.
