A dialysis system is disclosed. An example dialysis system includes a water treatment device configured to provide purified water and a dialysis machine including a dialysate holding tank, and a dialysate mixing pump connected to a source of concentrate. The dialysis machine is configured to prepare dialysate using the purified water by receiving an indication that a batch of dialysate is needed, transmitting a first message to the water treatment device to begin providing the purified water, and causing the dialysate mixing pump to pump a concentrate from the source of concentrate for mixing with the purified water to form the dialysate for storage in the dialysate holding tank. After the batch of the dialysate has been stored to the dialysate holding tank, the dialysis machine transmits a second message to the water treatment device to stop providing the purified water.

A hand-held or wearable device for cooling tissue of an eye of a patient is disclosed. In one aspect, the device includes a reservoir having fluid therein and a support connected to the reservoir and configured to be positioned on a face of the patient. The device also includes a nozzle positioned proximate to the support and fluidically connected to the reservoir, the nozzle configured to pass the fluid from the reservoir onto a surface of the eye. The device further includes a cooling element configured to cool the fluid from the reservoir such that it exits the nozzle at a temperature of between −100° C. and 15° C. The device further includes an ultrasonic vibrator positioned near the nozzle and configured to generate mist from at least part of the fluid.

Pump heads for peristaltic pump assemblies are provided. For example, a pump head for a peristaltic pump comprises an occlusion bed, a rotor guide, a rotor assembly positioned between the occlusion bed and the rotor guide, and a pathway for tubing. The pathway comprises an inlet portion, an outlet portion, and a connecting portion that connects the inlet and outlet portions. The inlet portion is defined between the occlusion bed and the rotor guide, the outlet portion is defined between the occlusion bed and the rotor guide, and the connecting portion is defined between the occlusion bed and the rotor assembly. Further, the occlusion bed is movable with respect to the rotor guide and the rotor assembly. In exemplary embodiments, the pump head urges fluid flow through the tubing to supply a cooling fluid to a medical probe assembly for delivering energy to a patient's body.

A device and a method for cooling living tissues for a medical purpose and other purposes are proposed. The device may include a container configured to accommodate a cooling medium, the container including a plurality of divided members each having a contact surface which is thermally coupled with the cooling medium. The device may also include a cooling generator configured to provide cooling energy to the container, and disposed on another surface of the divided member other than the contact surface. The device may further include a lubricating member provided to the contact surface of the divided member, wherein the container is configured to be thermally coupled with the cooling medium via the lubricating member.

The invention relates to the technical field of highland first aid, and particularly discloses a field first-aid infusion device for frigid highland zones. The device comprises a storage box, comprising a heat preservation and pressurization device, a marrow cavity puncture needle, a heat preservation infusion tube, a power-assisted puncture tool, a power supply and a power line, the heat preservation and pressurization device is electrically connected with the power supply through the power line, the heat preservation and pressurization device comprises a heating sleeve, magic tape is fixed to the surfaces of the two ends of the heating sleeve, a control box is fixed to the middle of the outer surface of the heating sleeve, and the power line is inserted into the control box.

A fluid infusion system includes an air pump connected to an accumulator tank to produce pressurized air that is stored in the accumulator tank. The system can include one or more fluid bag chambers wherein each fluid bag chamber includes an inflatable bladder positioned inside the fluid bag chamber to apply pressure on the fluid bag supported inside the chamber. The fluid bag can be connected by a tube set to deliver fluid from the fluid bag to a surgical tool at a surgical site. The fluid can, for example, be irrigation fluid or distention fluid. The system can include a controller connected to the pump to control the pump to produce the pressurized air and an adjustable pressure regulator can be connected between the accumulator tank and the inflatable bladder to control the pressure of air delivered to the inflatable bladder and the pressure that the fluid is delivered to the surgical tool. A pressure sensor can be connected between the adjustable pressure regulator and the inflatable bladder to measure the air pressure delivered to the inflatable bladder and send the air pressure measurements to the controller. The controller can configure the system display to show the air pressure measured by the pressure sensor.

A container for holding liquid is described. The container defines an inner region inside which liquid is adapted to be held and includes one or more walls for facilitating heating or cooling of the liquid therethrough, the one or more walls being adapted for invagination by a temperature control probe such that the temperature control probe extends into the container without directly contacting contents of the inner region of the container.
