  • Patent number: 6616634
    Abstract: The ergonomic syringe is used by an operator to inject fluid under pressure into a patient during a medical procedure, which can include angiographic procedures where catheters are used. Although said ergonomic syringe may be connected to and used with a catheter of any size, it is particularly suited for use by an operator to inject radiopaque dye through catheters having small diameters. The large handgrip and locations of the fingergrips, together with other features on these elements of the ergonomic syringe, increase comfort and reduce the fatigue, strain, and risk of disability which may be associated with achieving the force required for each injection to achieve high pressures necessary for proper dye density in the blood flow in the target blood vessels, where such force is greater in smaller catheters than in larger catheters.

  • Publication number: 20030105487
    Abstract: A hemostatic compression pad, for use with vascular compression devices, for application of pressure onto an area of a patient generally including a blood vessel and a wound site, such as a blood vessel puncture, during or after a medical procedure, where such procedure may be a cannulating procedure, for the purpose of controlling bleeding and achieving hemostasis. In use, the hemostatic compression pad, which is composed of at least two materials, is detachably connected to a vascular compression device and generally placed proximal to the catheter insertion site and over the blood vessel containing the cannula. The cannula is then removed from the blood vessel and pressure applied and maintained using the vascular compression device and hemostatic compression pad to compress the blood vessel for the purpose of controlling bleeding and, further, to achieve hemostasis. The improvement of this invention is its low propensity to slip laterally relative to the patient's body surface to which it is applied.

  • Publication number: 20030028214
    Abstract: 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, an elongate shaft and a pad. The shaft extends generally downward from the cente of the bottom side of the handle, The pad is connected generally at the center of its top side to the bottom end of the shaft. In use, the pad is generally placed proximal to the catheter insertion site and over the blood vessel containing the catheter. The catheter is then removed from the blood vessel and pressure applied to the gandle by the user in a downward direction to force the pad to compress the blood vessel for the purpode of controlling bleeding and, further, to achieve hemostasis. The entire vascular compression apparatus may then be discarded after use.
