A medical device comprising a syringe barrel, a plunger, and an injectable viscous lifting agent containing a coloring agent loaded in the syringe barrel. The injectable viscous lifting agent is sterilized by a sterilization process, such as an autoclaving process, while inside the syringe barrel. The injectable viscous lifting agent is adapted for injection between an upper mucosal layer and a lower layer at a target treatment site such that the upper mucosal layer separates from the lower layer and the upper mucosal layer is elevated.

Systems and methods for treating biologic fluids are disclosed. Some disclosed embodiments may be used to filter cerebrospinal fluid (CSF) from a human or animal subject, heat CSF to a target temperature, cool CSF to a target temperature, apply light treatment to CSF, separate cells via their dielectric properties, apply spiral and/or centrifugal separation, introduce additives to target particles, and/or apply combinations thereof. The method may include the steps of withdrawing fluid comprising CSF, treating the fluid, and returning a portion of the treated fluid to the subject. During operation of the system, various parameters may be modified, such as flow rate.

A low-cost and simple-to-use system and method to facilitate a prophylactic pleural lavage protocol at the time of thoracostomy tube placement for traumatic hemothorax in order to reduce the need for secondary intervention for the management of retained hemothorax. The invention may be used in conjunction with existing chest tubes and be administered at the time of initial chest tube placement, and continued at the bedside (by a bedside nurse) over the duration of chest drainage, as necessary. The system includes an operator device that semi-automatically administers a pleural lavage protocol consisting of saline instillation, and suction to slow the clotting process, prevent “gelling” of blood, and maintain drainability.

A heating device for blocking flow of air if the inside of a cartridge enters a negative-pressure state is provided. The device includes a cartridge upper plate having a fluid-guide member for guiding the flow of a fluid; a cartridge lower plate having an inlet, an outlet and another fluid-guide member positioned spaced apart from the fluid-guide member of the cartridge upper plate; a heater disposed between the cartridge upper plate and the lower plate and heating the fluid being guided by the fluid-guide members; air filters positioned outside the fluid-guide members and discharging air bubbles in the heated fluid into the atmosphere; and extension units which are provided on the cartridge upper and lower plates having film members and outflow and discharge passages and that keep the flow of fluid normal in the positive-pressure state and block the fluid movement pathway if a negative pressure occurs inside the cartridge.

A stimulation probe device including a first electrode, a stimulation module, a control module and a physical layer module. The stimulation module is configured to (i) wirelessly receive a payload signal from a console interface module or a nerve integrity monitoring device, and (ii) supply a voltage or an amount of current to the first electrode to stimulate a nerve or a muscle in a patient. The control module is configured to generate a parameter signal indicating the voltage or the amount of current supplied to the electrode. The physical layer module is configured to (i) upconvert the parameter signal to a first radio frequency signal, and (ii) wirelessly transmit the first radio frequency signal from the stimulation probe to the console interface module or the nerve integrity monitoring device.

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.

The disclosure is and includes at least an apparatus, system and method for a flexible heater sensor suitable for association with a fluid bag. The apparatus, system and method may include a conformable substrate on a ply of the fluid bag opposite a printed flexible heater; and a matched function ink set, printed onto at least one substantially planar face of the substrate. The matched function ink set forms: at least one conductive layer capable of receiving current flow from at least one power source; and at least one dielectric layer capable of at least partially insulating and at least partially limiting conductivity of the at least one conductive layer; wherein the matched ink set is matched to preclude detrimental interactions between the printed inks of each of the at least one conductive and dielectric layers, and to preclude detrimental interactions with the conformable substrate; and wherein the at least one conductive layer and the at least one dielectric layer comprise a sensing circuit that senses at least the temperature of fluid within the fluid bag.

A bilaterally driven intelligent control infusion device, comprising: infusion unit, the infusion unit comprises a drug storage unit, a piston and a rigid screw, the piston is arranged in the drug storage unit, a metal piece arranged on the piston, fixedly connected to the rigid screw; a driving wheel, provided with wheel teeth, drives the screw movement by rotation, the screw advances the piston to move; a driving unit cooperating with the driving wheel; and a power unit, connected to the driving unit, outputs forces in two different directions on the driving unit to lead driving unit to pivot; a position detector, interacted with the metal piece to generate signal; a program unit, connected to the infusion unit, convert the received signal into the piston position information and can control the driving unit to operate with different infusion rate according to requirements.

An infusion device. The infusion device includes a top portion comprising an introduction needle, and a bottom portion comprising a cannula, the top portion removably attached to the bottom portion, wherein the introduction needle is used to insert the cannula, and wherein after insertion, the top portion is removed from the bottom portion.

An apparatus, system, and method for contacting blood with ozone to kill microorganisms in the blood are described. The method involves injecting microbubbles of ozone containing gas into a flow of blood, preferably at a temperature of less than 12° C. The apparatus includes a blood flow conduit including a blood ozone contacting portion including a porous ozone injector.
