A catheter assembly includes a flexible catheter (22), a needle (12) having a sharp distal tip, the needle (12) disposed in the flexible catheter (22) and moving from a first position that exposes the needle (12) to a second position, an outer member (26) that is configured to engage and disengage a catheter hub (14), an inner member (28) disposed in the outer member (26), and a needle protection (30) member disposed in the inner member (28), the needle protection member (30) enclosing at least a portion of the needle (12) when the needle (12) is in the second position.

An insufflator for insufflating a body cavity includes a compressed air vessel and a flow control valve for delivering insufflating air to the cavity through a first trocar. A discharge control valve at an outlet port of a second trocar exhausts insufflating air from the cavity. A pressure sensor on the first trocar monitors cavity pressure, and a microcontroller operates the flow control valve for maintaining a predefined working pressure in the cavity. A foot operated switch is operable by a surgeon for opening and closing the discharge control valve. When the pressure in the cavity drops below the predefined working pressure, the flow control valve increases the insufflating air to the cavity, thereby increasing the insufflating air flow through the cavity for removing undesirable gases. The apparatus and insufflator may also be adapted for removing smoke, nitrogen or other undesirable gases during both cauterisation and cryogenic procedures.

Disclosed herein is a vertical-flat-arrangement-type suction and irrigation device which is easy to operate. The vertical-flat-arrangement-type suction and irrigation device includes a housing, a probe, and a suction and supply unit. The housing include a front chamber and a rear chamber spaced apart from each other and connected via a connection duct, a first duct connected to a front of the front chamber and extending forwards, a second duct connected to a rear of the front chamber and extending rearwards, and a third duct connected to a rear of the rear chamber and extending rearwards. The suction and supply unit includes a supply valve reciprocally moved inside the front chamber in an axial direction of the front chamber and a suction valve reciprocally moved inside the rear chamber in an axial direction of the rear chamber.

An ambulatory infusion device including a pump drive unit, a valve drive unit and a control unit. The pump drive unit includes a pump actuator and a pump driver coupled to a piston of a metering pump unit. The valve drive unit includes a valve actuator and a valve driver coupled to a valve unit for transmitting a valve switching force or torque. The control unit controls a repeated execution of: (a) placing the valve unit in a filling state; (b) displacing the piston in a retraction direction; (c) displacing the piston in an advancing direction by a backlash compensation distance; (d) switching the valve unit from the filling state into a draining state; and (e) further displacing the piston in the advancing direction in a number of incremental steps over an extended time period.

One aspect of the disclosure includes a respiratory valve apparatus. The respiratory valve apparatus may include: a housing having an inner chamber, an endotracheal tube connection port, a ventilator connection port, and a resuscitation bag connection port; and a piston assembly positioned within the inner chamber and including a piston having a first passageway and a second passageway through the piston, wherein the first passageway provides a first flow pathway between the endotracheal tube connection port and the ventilator or connection port when the piston is in a first position, and wherein the second passageway provides a second flow pathway between the endotracheal tube connection port and the resuscitation bag connection port when in a second position.

Disclosed is a valve for use in a pump for a wearable drug delivery device for moving a liquid drug from reservoir into a pump chamber and thereafter from the pump chamber to a patient interface. The valve can comprise two needles, a first needle in fluid communication with the reservoir and a second needle in fluid communication with the patient interface. The first and second needles may be linearly translated to either cover the lumen opening of a needle with a septum or place the lumen opening of the needle in fluid communication with the pump chamber. When the first needle is in fluid communication with the pump chamber, the liquid drug may be transferred from the reservoir to the pump chamber via suction created by a plunger in the pump chamber. When the second needle is in fluid communication with the pump chamber, the liquid drug may be transferred from the pump chamber to the patient interface via a pressure created by the plunger in the pump chamber.

A catheter assembly includes a flexible catheter (22), a needle (12) having a sharp distal tip, the needle (12) disposed in the flexible catheter (22) and moving from a first position that exposes the needle (12) to a second position, an outer member (26) that is configured to engage and disengage a catheter hub (14), an inner member (28) disposed in the outer member (26), and a needle protection (30) member disposed in the inner member (28), the needle protection member (30) enclosing at least a portion of the needle (12) when the needle (12) is in the second position.

A drug delivery device comprising a delivery unit (2) including an internal reservoir (8), a subcutaneous delivery mechanism (6), a pump for pumping liquid from the internal reservoir to the subcutaneous delivery system, and a liquid filling mechanism (12) configured for injecting liquid from an external vial (16) or reservoir into the internal reservoir. The liquid filling mechanism comprises a filling port (14) and a valve mechanism (18) selectively operable to: open a first fluid path (54) extending from the filling port to the internal fluid reservoir and close a second fluid path (56) extending from the internal reservoir to the subcutaneous delivery member, or close the first fluid path and open the second fluid path. The valve mechanism comprises a valve housing (48) fixedly mounted in relation to a housing of the drug delivery device and a valve stem (50) rotatably received within the valve housing, whereby the first fluid path and the second fluid path are selectively operated by the rotational position of the valve stem in relation to the valve housing, such that when the valve stem is in a first position, the first fluid path is open while the second fluid path is closed, and when the valve stem is in a second position, the second fluid path is open while the first fluid path is closed.

Fluid flow manifold assemblies for use in fluid flow sets are provided. The fluid flow manifold assembly includes a body having a main fluid channel and a reinforcing plate, the main fluid channel having a fluid inlet, a fluid outlet and a drug port. A flow control assembly is disposed opposite the main fluid channel from the drug port. The flow control assembly is configured to shut off fluid flow through the drug port into the main fluid channel with a plunger of the flow control assembly in a closed position and to allow incremental levels of fluid flow through the drug port into the main fluid channel by variably retracting the plunger based on rotation of a knob of the flow control assembly.
