A process, apparatus and a catheter and a flexi needle for medical applications formed by the process of selecting a tubular flexible member and a metal/ceramic cap member to be securely joined to the tubular member, placing the cap member in engaging relation with a holding member of a material joining device, securing the tubular member on a positioning member of the material joining device, positioning a distal end of the tubular member in engaging relation with an end of the cap member positioned in the holding member, and rotating the holding member and maintaining the tubular member in frictionally engaging relation with the cap member to melt or soften a predetermined portion of the distal end of the tubular member engaged with the cap member to integrally join a predetermined portion of the distal end of the tubular member within the cap member forming a joined composite member.

A method of power injecting a contrast medium into a patient, including obtaining a power-injectable access port suitable for power injection. The power injectable access port includes a housing defining a reservoir, and a septum. The septum may include a self-sealing material, and a radiopaque material. The radiopaque material may form a selected pattern when an x-ray is taken through the septum for identifying the power-injectable access port as being suitable for power injection. The power-injectable access port may be structured for accommodating a pressure developed within the reservoir of at least 35 psi, and may be designed to accommodate a fluid flow rate of at least 1 milliliter per second. After implanting the power-injectable access port in the patient, the method may include imaging the power-injectable access port and confirming via the selected pattern in the septum that the power-injectable access port is suitable for injecting the contrast medium.

A medical injection and suction device includes: a housing that encloses a driving motor; a syringe mount disposed on a wall of an upper side of the housing; a plurality of valves disposed on the wall of the upper side of the housing and on a side of the syringe mount; a slider that moves toward or away from the housing and is disposed on a lateral side of the housing; a driving rod connected to the slider; and at least one slide rod. The driving rod extends through a wall of the lateral side of the housing. An end of the driving rod is connected to the driving motor. The driving motor drives the driving rod to move the slider. An end of the at least one slide rod is connected to the wall of the lateral side of the housing. The slider is disposed in a slidable manner on the slide rod.

An apparatus for use in tube feeding has a cylindrical body provided with first and second openings connected by a flow channel. The body has a reagent, for determining a characteristic of fluid disposed in the body and a transparent window to view the reagent. In use, a first end of an internal feeding tube releasably engages with the first opening. The second, distal end of the feeding tube is disposed inside a patient. A second feeding tube engages with the second opening. The second feeding tube connects the apparatus to a bi-directional pump operable: to pump internal fluid from a reservoir, through the apparatus and into the internal feeding tube; and to pump fluid from the patient into the body of the apparatus. This allows a user to pump fluid from the patient into the body of the apparatus to react with the reagent.

A system for controlled delivery of medical fluids to a patient includes an inlet conduit attached to a source of a medical fluid and an outlet conduit connected to the patient. The inlet and outlet conduits are interconnected by a multiple stage control valve assembly and a pair of syringes. The control valve assembly is alternated between a first state wherein the inlet conduit communicates with a first syringe for transmitting fluid from the source to the first syringe, a second state wherein the first syringe communicates with a second syringe and is isolated from the inlet conduit and the outlet for transmitting fluid from the first syringe to the second syringe, and a third state wherein the second syringe communicates with the outlet and is isolated from the inlet and the first syringe for transmitting fluid from the second syringe to the patient through the outlet.

An access port for providing subcutaneous access to a patient is disclosed. In one embodiment, the port includes an internal body defining a fluid cavity that is accessible via a septum. A compliant outer cover including silicone is disposed about at least a portion of the body. A flange is included with the port body and is covered by the outer cover. The flange radially extends about a perimeter of the port body proximate the septum so as to impede penetration of a needle substantially into the outer cover in instances where the needle misses the septum. The flange can further include both an anchoring feature for securing the outer cover to the port body and an identification feature observable via x-ray imaging technology for conveying information indicative of at least one attribute of the access port. The outer cover provides a suitable surface for application of an antimicrobial/antithrombotic coating.

The invention is an accessory configured to be fitted to an electrical surgical device and provide suction at a surgical site in which the electrical surgical device is being used. In particular, the accessory is in the form of a suction collar configured to be releasably coupled to the electrical surgical device, generally adjacent to a working end thereof, and provide suction to minimize the accumulation of excess steam, fluid, and/or debris from the surgical site during the treatment procedure. The suction collar is further configured to apply a sufficient suction force to a patient's skin surrounding the surgical site to aid in stabilizing the electrosurgical device in place and maintain the working end to the electrosurgical device within the surgical site during the procedure.

An assembly used in the injection of a contrast product into a patient is disclosed. This assembly includes a container, an injection flowpath, and a filling flowpath. The injection flowpath extends from the container to the patient, while the filling flowpath extends from a feed source to the container. Part of the injection flowpath is also used by the filling flowpath. One connector is disposed between an upstream filling line tubular section and a pump coupling section within the filling flowpath, while another connector is disposed between a downstream filling line tubular section and this same pump coupling section. This allows the upstream filling line tubular section, the pump coupling section, and the downstream filling line tubular section to differ in one or more respects, for instance with regard to hardness.

An anesthetic tank includes an insertion mouth for inserting an injection adapter of an anesthetic container, and a storage portion communicating with the insertion mouth. A volatile anesthetic inside of the anesthetic container is injected into the storage portion. An identifying member is arranged on the outside of the insertion mouth and is rotatable around the center axis of the insertion mouth. The identifying member has key groove formed in the internal surface of an insertion hole for inserting the injection adapter. The key groove are used for identifying the type of the volatile anesthetic in collaboration with keys formed in the injection adapter. A cover member has an opening formed in the position facing the insertion mouth and the insertion hole and presses the peripheral part of the identifying member.
