An occludable venous catheter device includes a needle tube with a needle tube base; a venous catheter with a venous catheter base; a sealer, a front portion disposed inside a venous catheter lumen, a front end exposed out of a front-end opening; an occluding wire; an isolating element; a guide passage with a straight tube portion; a front-end opening connected to the venous catheter lumen; wherein the occluding wire is capable of entering the venous catheter lumen; the straight tube portion is coaxial with the venous catheter or is capable of moving in an externally-isolated manner to a position such that a central axis of the straight tube portion coincides with a central axis of the venous catheter; the occluding wire and the guide passage reach directly inside a chamber and are isolated from the outer environment.

Systems and methods for pressure sensors being located in various components of a surgical medical gases delivery system (such as for laparoscopic surgery) are disclosed. The pressure sensors can enable gas supply (either of a surgical medical gases delivery system or supplementary to such a system) to sense pressure so as to safely insufflate the surgical cavity in a controlled manner. Advanced pressure sensing can also be provided to achieve specific flow algorithms and/or non-standard flow patterns that may help achieve functionality for mitigating smoke accumulation in the surgical cavity and/or impairment to vision, and helping to improve stability in the surgical cavity. The pressure sensing disclosed herein can allow for more control over the fundamental aspects of gas control and supply in the surgical gas delivery system, better performance, and outcomes of the surgery, and better incorporation of a humidification therapy.

Devices, and methods for generating variable inhalable products (e.g., variable density, phase, and size products) are provided. Methods for treating or preventing a disorder in a subject using variable products generated by the devices are also provided herein. Additionally, inhalers and breathing systems comprising the devices are provided.

Dialysis machines and methods for operating dialysis machines (e.g., peritoneal dialysis machines) may include delivering dialysate to a patient and detecting a temperature of a volume of the dialysate, an air content of the dialysate volume, or another condition, or combinations thereof, wherein the detected temperature of the dialysate volume is compared to a predetermined maximum temperature, the detected air content of the dialysate volume is compared to a predetermined maximum air content and the detected other condition generates a signal. The volume of dialysate may be diverted in response to the detected temperature exceeding the predetermined maximum temperature, the air content exceeding the predetermined maximum air content, or the other condition generated signal, or combinations thereof.

A method of sanitizing liquid for use in a. medical device, the method comprising the steps of providing a medical device defining a water circuit with a volume of liquid, sensing the temperature of the volume of liquid with a sensor, heating the volume of liquid from an initial temperature to exceed a threshold temperature, maintaining the volume of liquid above the threshold temperature, determining a time-temperature value for the volume of liquid periodically once the threshold temperature has been exceeded, calculating a. cumulative time-temperature value and providing an output signal once the cumulative time-temperature value has reached a level indicative of a sanitizing dose. A medical device and a liquid sanitizer are also disclosed.

A sorbent cartridge for use in a portable wearable renal therapy system, and a method of using same is provided. The sorbent cartridge comprises: a inlet and an outlet, the inlet configured to receive process fluid from renal therapy device and the outlet configured to discharge treated process fluid; a hydrogel configured to absorb and adsorb a toxin from the process fluid without use of a dialysate to purify the process fluid. The inlet and the outlet are each configured to releasably couple to the renal therapy device for removing the sorbent cartridge.

A case for a mobile device including a back section and a first front section and a second front section, the first front section being adapted for connection to and separation from the second front section and the back section including an opening for receiving a mobile device; a receiving space located within the first front section and second front section for receiving an injection device, wherein the injection device is at least partially visible when the second section is detached from the first section; a release latch located on one or more of the first front section and second front section for facilitating separation of the second front section from the first front section; and a connector portion for connecting the back section to the first and second front sections.

A medical infusion fluid handling system, such as an automated peritoneal dialysis system, may be arranged to de-cap and connect one or more lines (such as solution lines) with one or more spikes or other connection ports on a fluid handling cassette. This feature may reduce a likelihood of contamination since no human interaction is required to de-cap and connect the one or more lines and the one or more spikes. For example, the automated peritoneal dialysis system may include a carriage arranged to receive the one or more lines each having a connector end and a cap. The carriage may move along a first direction so as to move the connector ends of the one or more lines along the first direction, and a cap stripper may be arranged to engage with the caps on the one or more lines on the carriage. The cap stripper may move in a second direction transverse to the first direction, as well as to move with the carriage along the first direction.

System and method for identification and verification of authorization of a subject to use a substance delivery device.

A surgical humidification system includes a source of gas flow and a humidifier that receives the gas flow and outputs a humidified gas to a delivery conduit. The delivery conduit has an outlet and a suitable interface, such as a diffuser, is connected to the outlet. The interface can be positioned near or within an open surgical cavity of a patient to supply the humidified gas to the cavity. The system also includes a pressure relief arrangement that operates to relieve pressure from the system above a normal operating pressure. The pressure relief arrangement can be located in a non-sterile portion of the system, such as upstream from the humidifier, for example.
