  • Publication number: 20240050647
    Abstract: A dual chamber single-hand pump is described that includes a pump chamber with four fluid pathways. Two pathways are configured to conduct fluid to the chamber and to stop flow therethrough from the chamber, and two pathways are configured to conduct fluid from the chamber and to stop flow therethrough to the chamber. A piston positioned and moveable within the chamber separates two of the pathways from the other two pathways within the chamber. The pump can be held in a single hand by having finger grips for stabilizing the pump and a palm grip for advancing the piston. A return spring can return the piston to the original position when the palm is relaxed to allow expansion of the spring.

  • Publication number: 20230390532
    Abstract: A catheter system may include a catheter hub, a catheter tube, a needle carrier, a needle extending distally from the needle carrier and through the catheter tube, a guidewire slider, and a guidewire extending distally from the guidewire slider. The guidewire slider may be configured to couple to the needle carrier in response to sliding of the guidewire slider. The catheter system may include a safety slider configured to slide with the guidewire slider from a proximal position to a distal position. In response to the guidewire slider and the safety slider sliding together from the proximal position to the distal position, the safety slider may be configured to couple to a proximal end of the needle carrier. In response to rotation of an additional slider into a cutout tab of a housing, the guidewire slider may be configured to uncouple from the additional slider.
