A manually operated medicament infusion device is provided. The device is capable of delivering an accurately controlled volume of medicament with reliability. Additionally, the device includes a battery-operated indication device for tracking the number of doses of medication delivered. Optionally, the device includes a ratchet and pawl to prevent inadvertent dispensing of medicament.

Disclosed is an ambulatory therapeutic fluid delivery device. The device includes at least one housing connectable to a cannula, the at least one housing retaining a reservoir to hold the therapeutic fluid. The device also includes a mechanically powered pumping mechanism to cause delivery of at least some of the fluid from the reservoir, and a power-transfer mechanism to transfer manually-delivered power provided by a user to mechanically actuate the pumping mechanism.

A high pressure delivery device for delivering a medicament includes a first chamber for storing a supply of the medicament and a second chamber in fluid communication with the first chamber. A fluid connection path is in fluid communication with the second chamber for administering the medicament. A valving system is in fluid communication with the first chamber, the second chamber and the fluid connection path. The valving system allows a dose of the medicament to be injected from the first chamber into the second chamber while substantially preventing backflow of the dose into the first chamber and substantially preventing leakage through the fluid connection path. The valving system also allows the dose in the second chamber to be administered through the fluid connection path while substantially preventing the dose from flowing back into the first chamber.

Devices used to deflate an inflatable hemostasis device are disclosed. The devices may be configured to deflate the inflatable hemostasis device in staged increments over a period of time. The devices may include a barrel member and a plunger member comprising an insert configured to couple with a retention ring of the barrel to restrict a retraction distance of the plunger member.

A method and a system are described for administrating an infusion liquid pulse. The system includes a tubing system having an inlet connected to an external reservoir adapted to contain infusion fluids and an outlet connected to a catheter. The tubing system includes a check valve proximate to the inlet and an anti-siphon valve proximate to the outlet. The system further includes an automatic pulse flow generation device. The automatic pulse flow generation device includes an internal reservoir and a bidirectional pump configured to pump infusion fluid from the external reservoir to the internal reservoir and further pump an infusion fluid pulse from the internal reservoir to be infused by a catheter, the infusion liquid pulse has a volume of at least 2 ml and a velocity of at least 5 ml/min.

A pressure solution of an infusion solution holder has a collar that is ergonomically fitted to the shape of the shoulders. The collar includes a pressure tank integrally with the holder and a tank containing the infusion solution. Since the tank containing the infusion solution is located on the patient's shoulders and vertically close to the supply point of the infusion solution, there has to be sufficient pressure in the tank in order for a successful infusion. Therefore, the collar's pressure tank is pressurized by the element, whereby the pressure in the pressure tank is pressing the solution tank and creates the necessary pressure at the time of infusion. The pressurization of the pressure tank is shown in the most cost-effective way by pumping with a manual pressure element, such as a ball pump. Pressurization can also be made, for example, by an electric pump.

A portable therapeutic fluid delivery device and a method for delivering a therapeutic fluid into a body of a patient are provided. In one aspect the therapeutic fluid delivery device and the method can be implemented using at least one housing securable to the body of the patient, a reservoir coupled to the at least one housing, a therapeutic fluid dispensing mechanism, a memory component, a controller, at least one bolus delivery button configured to signal the controller to initiate the delivery of the therapeutic fluid into the body of the patient; and, an inadvertent initiation prevention mechanism adapted for preventing the patient from activating the at least one bolus delivery button.

Disclosed is an ambulatory therapeutic fluid delivery device. The device includes at least one housing connectable to a cannula, the at least one housing retaining a reservoir to hold the therapeutic fluid. The device also includes a mechanically powered pumping mechanism to cause delivery of at least some of the fluid from the reservoir, and a power-transfer mechanism to transfer manually-delivered power provided by a user to mechanically actuate the pumping mechanism.

IV sets including a plurality of hand pumps and methods of use thereof are described herein. An IV set includes a first portion of tubing, a second portion of tubing, and a drip chamber. The drip chamber includes a spikeless inlet fluidically coupled to the first portion of the tubing, an outlet fluidic ally coupled to the second portion of the tubing, and a curved drop former positioned within the drip chamber between the inlet and the outlet. The curved drop former is configured to receive a fluid via the spikeless inlet and form, based on a curvature of its surface, one or more droplets having a substantially uniform consistency and flowing at a substantially constant rate through the drip chamber.

Described herein is an add-on device for an intravenous (IV) set hand pump comprising a first member configured to actuate the handpump, a second member hingedly connected to the first member and configured to receive the hand pump, wherein, when actuated, the add-on device is configured to increase a fluid flow rate downstream of the IV set hand pump beyond a maximum gravity-based fluid flow rate of the IV set.
