A marking implement assembly for placing a mark on tissue, including a marker body including a marking implement extending from the marker body, a cap configured to fit to an end of the marker body so as to cover the marking implement, the cap including a housing providing an ink reservoir, where when fitted to the marker body at least a part of the marking implement is in fluid contact with the ink reservoir, the cap fitting onto the marker body in fluid tight manner.

A system for filtering vaporized medicinal compounds includes a vaporizer configured to release one or more volatilized medicinal compounds in gaseous form, together with solid or semi-solid particulate byproducts, and one or more removable filters for efficiently removing at least a portion of the particulate byproducts while allowing passage of medicinally active volatilized compounds. The vaporizer includes a mouthpiece through which one or more volatilized medicinal compounds may be drawn. The filter is made of a chemically inert material (e.g., polypropylene or other polyolefin) and may be configured to detachably interface with an exposed surface of a vaporizer mouthpiece. The filter acts to remove solid or semi-solid particulate matter passing through the mouthpiece with minimal chemical and/or physical interference with volatilized medicinal compounds, which pass through the filter. The removable filter can also prevent cross-contamination by multiple users of the vaporizer.

Disposable set for an extracorporeal blood treatment system. The disposable set includes an extracorporeal blood circuit having a blood withdrawal line and a blood return line configured to be attached to a blood treatment device and an infusion circuit coupled to the extracorporeal blood circuit through infusion lines. The disposable set further includes an infusion valve unit configured to be releasably connected to an infusion pump of the extracorporeal blood treatment system, the infusion valve unit incorporating a one-way valve or seal to control the flow of infusion liquid through the infusion cicuit.

An electronic cigarette includes a housing, a sleeve, an atomizer, a latch assembly and a control assembly. The sleeve includes a first limiting position and a second limiting position. The atomizer includes a mouthpiece. The atomizer is capable of being inserted into the sleeve and telescoping relative to the sleeve along an axial direction of the sleeve, so as to expose the mouthpiece or take out the atomizer from the sleeve. The latch assembly is arranged on an end of the atomizer opposite to the mouthpiece and configured to latch the atomizer in the sleeve when the atomizer is retracted into the sleeve and is positioned at the first limiting position. The control assembly is arranged on the sleeve and configured to unlock the latch assembly to allow the end of the atomizer to move to the second limiting position along the axial direction of the sleeve.

A breathing treatment apparatus delivers breathing gas to a user. The apparatus may be configured to comprise one or more sensors for sensing microbial growth within the apparatus.

A system and method is provided to allow multiple patients to receive peritoneal dialysis treatment at a walk-in facility without having to keep fresh dialysis solution on hand themselves. The walk-in facility is enabled to receive a peritoneal dialysis prescription from a patient, verify the prescription, determine the appropriate treatment for the patient, provide the patient with the appropriate dialysis solution in the appropriate amount, and enable the patient to undergo a dialysis treatment at the facility. The walk-in facility can also be enabled to monitor the patient's home dialysis treatment and to adjust the patient's treatment at the facility accordingly. The facility can be enabled to produce dialysis solution on demand by manufacturing the solution from solution components according to a patient's prescription. Moreover, the facility can use a sorbent system to regenerate effluent dialysis solution into fresh dialysis solution.

Systems, methods, and devices related to removing fluids from a patient are provided. In one instance, fluid is removed from the patient and delivered to a canister using reduced pressure. Reduced pressure is supplied to the canister via a reduced-pressure delivery conduit that includes a moisture processing device and a hydrophobic filter. The moisture processing device condenses moisture from the air to prevent condensation from occluding the hydrophobic filter. The moisture processing devices includes an expanded volume and one or more liquid-impermeable, vapor-permeable membranes. The liquid-impermeable, vapor-permeable membrane allows vapor to egress the moisture processing device. Other systems, methods, and devices are presented.

A liquid medicine injection apparatus capable of injecting an additional fluid after completion of injection of a liquid medicine is provided. The apparatus includes a cylinder elongated in a direction and having a nozzle formed at one end of the cylinder; a piston installed to be hermetically movable within the cylinder in the direction; an injector provided at the other end of the cylinder to allow the piston to be moved; a fluid tank for storing a fluid in a sealed state; a needle unit disposed between the nozzle and the fluid tank; and a cap member provided between the needle unit and the fluid tank and deformable to allow the needle unit to penetrate the fluid tank.

A measurement device and a method for monitoring a condition of a patient. The measurement device includes: a gas-guide apparatus, configured to operatively connect between an medical gas provider and a patient side of the measurement device, and deliver medical gas from the medical gas provider to the patient; and at least one sensing apparatus, placed on an outer surface of the gas-guide apparatus and configured to detect real-time measurement data of the medical gas passing through the gas-guide apparatus. In this way, the at least one sensing apparatus is placed on the outer surface of the gas-guide apparatus, since the measurement data is a relative value which indicates a change of internal environment of the gas-guide apparatus, this can also avoid a problem of contamination compared with setting a sensor inside a respiratory device, thus improving the security of the measurement.
