The present invention relates to an extensible drug injection device capable of injecting a drug from a location away from a patient, and an operation method therefor. Disclosed is a drug injection device comprising: a first sub-line of which one end joins with a main line, connected from a first drug storage part for storing a first drug to be injected into a patient to the body of the patient such that the first drug flows therein, and of which the other end is extended to the other side; a second drug injection part which is connected to the first sub-line and which injects a second drug that is different from the first drug; and a second drug pumping part which is connected to the first sub-line, and which pushes, to the main line, the second drug having been injected by the second drug injection part into the first sub-line.

Bubble traps for use in medical fluid lines and medical fluid bubble trap systems are disclosed herein. In some embodiments, the bubble trap is configured to trap gas (e.g., air) that flows into the bubble trap from a fluid line. In some embodiments, the bubble trap includes an inlet and an outlet and a chamber between the inlet and the outlet. For example, in some embodiments, the bubble trap is configured to inhibit gas from flowing into the outlet once gas flows into the chamber from the inlet. In some embodiments, the bubble trap is in fluid communication with a source container, a destination container, and/or a patient.

The present disclosure describes a flow reversing valve, along with associated methods and systems for providing forward flow, reverse flow, and bypass flow modes of operation, and integrating them into patient treatment systems, including those used for treating and inducing hyperthermia.

A surgical access port or trocar is provided. The trocar has a trocar seal housing and a trocar cannula with an optical obturator insertable through the trocar seal housing and the trocar cannula. The trocar is configured to access a body cavity, to maintain positive pressure and to prevent loss of surgical insufflation gas used in laparoscopic procedures. The trocar seal housing can be releasably attached to the trocar cannula. The trocar seal housing may also have a shield and/or alignment channel that provide protection or assist in operation of instrument and zero seals housed in the trocar seal housing.

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.

An example connector for a balloon catheter assembly according to an example of the present disclosure includes, among other possible things, an inlet branch, a first outlet branch in fluid communication with the inlet branch and configured to be connected to a first balloon, a second outlet branch in fluid communication with the inlet branch and configured to be connected to a second balloon, and a valve integrated the first outlet branch. The valve has a first position and a second position. The valve is configured to limit fluid flow through the valve when in the first position. Another example connector for a balloon catheter assembly and a method of inflating a balloon catheter assembly are also disclosed.

A system for feeding and evacuation has a feeding tube in place into a subject's stomach cavity, having a Luer-Lock compatible female connector on an outboard end, a feed source, a unique Lopez valve having a conventional connector on one end and a male Luer-Lock connector on the other end in place of the conventional tapered connector, a suction tube coupled to a suction source, the suction tube having a connector compatible with the conventional connector of the conventional Lopez valve on an end away from the suction source. With the feeding tube connected to the feed source, nutrients are supplied to the subject through the feeding tube, and with the feed source disconnected, the body of the unique Lopez valve connected to the feed tube by the male Luer-Lock extension and to the suction tube, the subject's stomach cavity is exposed to suction controlled by the conventional Lopez valve.

A fat harvesting system and related methods of harvesting and reinjecting fat that provides a medical professional with multiple technique options. Harvested fat can be subjected to a variety of pre-reinjection preparation steps within a single, self-contained reservoir such that the potential for contaminating the harvested fat is avoided. The fat harvesting system can be completely self-contained kit requiring no additional external systems or alternatively, can utilize available surgical suite systems, for example, vacuum to successfully harvest, prepare and reinject fat cells. The fat harvesting system can size harvested fat cells so as to be especially desirable for different injection locations in the body. The fat harvesting system is a single use, disposable system that requires no sterilization equipment and recovered and sized fat cells are maintained in a sanitary environment so as to avoid contamination that could result in having to discard recovered fat cells.

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.
