71 results about "Intravenous fluid tubing" patented technology

A pump for pumping fluid includes a tube platen, a plunger, a bias member, inlet and outlet valves, an actuator mechanism, a position sensor, and a processor. The plunger is configured for actuation toward and away from the infusion-tube when the tube platen is disposed opposite to the plunger. The tube platen can hold an intravenous infusion tube. The bias member is configured to urge the plunger toward the tube platen.

The invention concerns an arrangement to couple an intravenous hose having a roller clamp with an infusion pump. A hose clamp has clamping surfaces in the form of legs which can move relative one another about a hinge, the legs being enveloped on their outside by a biased clamping spring, and the device is formed by an expander rib that is fastened on the inside of the door and can be brought into engagement with the legs of the hose clamp so to produce the open position after closing the door to expand the legs. The housing has a receiver, into which the hose clamp can be snapped, and that a locking device is present in the housing that prevents the closing of the door if the hose clamp is not inserted into the receiver and permits the closing of the door when the hose clamp is fully inserted.

A long-sleeved, pullover-type upper body garment has a continuous slit, which runs up the side of the garment from the bottom of garment body to an arm pit, and downward along the underside of a sleeve, and terminates at a point intermediately along the length of the sleeve. The segment of the slit that is in the body of the garment is temporarily closeable using mating hook-and-loop fastener members that are attached to the body of the garment on opposite sides of the slit. The segment of the slit in the upper portion of the sleeve remains at all times “open”, thereby allowing access to the middle and / or upper end of the wearer's arm for attachment of IV tubing or other medical lines. The circumference of the lower end (e.g., forearm portion) of the sleeve is neither separable nor openable, thereby requiring that a wearer insert his / her hand through the lower portion of the sleeve. The garment can be donned or removed by a patient to whom mid-arm medical lines are attached, without necessitating detachment of the medical lines. Conversely, mid-arm medical lines can be attached to a wearer's arm without necessitating rolling up of the sleeve or removal of the garment.

A drip chamber having an upper reservoir that is separated from a lower reservoir via a filter assembly, wherein a distance between the filter assembly and a bottom surface of the drip chamber is selected to prevent dislodged air bubbles of the filter assembly from being drawn into an intravenous fluid line that is coupled to the bottom surface of the drip chamber, during an infusion procedure.

The invention provides a multi-bottle automatic continuous penetrating venous infusion apparatus which comprises a cork puncture outfit (1), an air filter (2), a hose (3), an observation window (4), a flow regulator (5) and an injection needle (6) of the present venous infusion apparatus, and is characterized in that: the parts containing a switch float valve cavity (7) and a circuit switch cavity (8) are additionally arranged in a venous infusion pipeline, and a solenoid valve (24) and an alarm (25) are mounted in parallel in a circuit related to the circuit switch cavity (8). The multi-bottle automatic continuous penetrating venous infusion apparatus can be used for realizing the automatic continuous penetration for multi-bottle liquid medicines without manual switching and automatically cutting off the venous infusion pipeline while alarming when the infusion of the liquid medicine in the tail bottle is ended. By using the multi-bottle automatic continuous penetrating venous infusion apparatus, the working strength of nursing personnel is greatly relieved, the nursing load of an infusion patient or nursing personnel is reduced, the generation of unforeseen circumstances is reduced, and the market developing value is higher.

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.

Mandrel supported IV tubing is inserted within a mold of a mold assembly to heat the IV tubing and form a tapered end of the tubing. The tip of the tubing extending beyond the tapered end of the tubing is severed by the mandrel bearing against the mold to lodge the tip in an outlet of the mold. Cooling air is introduced to the mold assembly to cool the mold and to create a flow of turbulent air about the outlet of the mold to extract the severed tips. The turbulent air is exhausted through a channel, pipe and fitting into a collection chamber and causes translation of the severed tip to and into the collection chamber. Sensors may be incorporated to sense the translation of the severed tips.
