  • Publication number: 20230338725
    Abstract: Pinch-style clamps can be designed for use in clamping or occluding plastic tubing, such as intravenous tubing. These pinch clamps can include a soft, polymer material applied to various surfaces of the pinch clamp to prevent abrasion or irritation to the patient, increase friction between the pinch clamp and the user operating said pinch clamp, increase friction between engaged surfaces of the pinch clamp to prevent premature or unintended disengagement of the clamp, or increase friction between the outer surfaces of the tubing and the clamping surfaces of the clamp. Various features or components can be employed to prevent lateral disengagement of the pinch clamp. A pinch clamp may also be configured with rounded outer edges to enhance patient comfort.

  • Publication number: 20200384185
    Abstract: A device to flush a catheter assembly may include a first extension tube and a first connector, which may be coupled to a distal end of the first extension tube. The device may include a second extension tube and a second connector, which may be coupled to a distal end of the second extension tube. The device may include a syringe and an extension, which may be coupled to the syringe. In some embodiments, a first fluid pathway may extend through the first extension tube, and a second fluid pathway may extend through the second extension tube. In some embodiments, a third fluid pathway may extend through the extension. In some embodiments, the third fluid pathway may branch into the first fluid pathway and the second fluid pathway.
