In alternative embodiments, provided are mechanical ventilators and methods for making and using them.

A ventilator includes at-least one air vessel, at-least one inflation bag, at-least one connecting member, a bag holder and at-least one controller member. The at-least one connecting member connects to the at-least one air vessel. The bag holder may hold the inflation bag. The at-least one controller member operates the at-least one inflation bag thereby changing size of the inflation bag to vary a tidal volume and an inspiration-expiration ratio of the ventilator. In another aspect, at-least one controller member is mounted on the bag holder. Further, the at-least one controller member slides within the bag holder to change the shape of the inflation bag to vary a tidal volume and an inspiration-expiration ratio of the ventilator.

An adipose tissue (AT) transfer system includes, on the aspiration side, an aspiration cannula, an aspiration pump, a container, and flexible tubing connecting the aspiration cannula to the container. On the reinjection side, the system includes a reinjection cannula, flexible tubing connecting the inlet of the reinjection cannula to the container, and a reinjection pump imposing positive-displacement pumping action on the flexible tubing and causing movement of AT in a continuous or pulsed mode. The aspiration pump operates to continually supply harvested AT to the second flexible tubing while the reinjection pumps causes continuous or pulsed deposition of the AT at the injection site. To ensure that internal pressure and/or flow of the AT through a channel of delivery of the AT to the reinjection site does not exceed a predetermined value, the system contains an external pressure sensor configured to measure such internal pressure in absence of a part that is in direct contact with the AT.

A device for infusing a medicament into a patient includes a disposable component having a collapsible reservoir for holding the medicament, a cannula, and an elastomeric tube connected in fluid communication between the reservoir and the cannula. A manipulator is mounted on a chassis for engagement with the elastomeric tube. The manipulator includes a piston and respective pinchers upstream and downstream from the piston for a close/open open/close changeover operation. In concert therewith, the piston cyclically advances and withdraws relative to a platen to thereby alternatingly dilate/constrict the tube section. When the upstream pincher is open, the piston withdraws to create a low fluid pressure, p.sub.Lo, in the tube section to draw medicament into the tube. Alternately, when the downstream pincher is open, the piston is advanced to create a high fluid pressure, p.sub.Hi, on the tube to infuse medicament into the patient.

The present invention discloses ventilation apparatus, comprising a casing with a first vent and a second vent, a fixed spacer disposed within the casing, and a movable spacer in operative connection with a power mechanism. Also discloses herein are methods for ventilating a subject, by synchronously providing a positive pressure ventilation and a negative pressure ventilation using the ventilation apparatus described herein.

The present invention provides a 2-way air flow type dispenser for spraying powder and a powder sprayer including the same. The present invention adopts a 2-way air flow manner in which an air flow causing the powder to be sprayed and an air flow causing the powder to be transferred from a container to a spraying nozzle are separately formed, thereby enabling the smooth spraying of the powder.

An oscillating positive expiratory pressure system including an oscillating positive expiratory pressure device, an adapter coupled to the device, and a control module coupled to the adapter. The control module provides real time information about the use of the device, and provides feedback and storage of the information to improve the use thereof.

A method and a wash, clean and dry system are provided for washing, cleaning and drying a surface region of a human body. The system includes a toilet seat assembly with a bidet assembly having a spray canister device for spraying the surface region with a solution, such as a skin protecting barrier solution, a cleaning solution or a medicated solution. In one aspect, the spray canister device can be movably insert into and out of the toilet seat assembly and is easy to operate and use. In addition, the bidet assembly further includes a spray nozzle assembly and a drying nozzle assembly, which are adapted to wash, clean and dry the region of the human body in three dimensional moments. The removable spray canister device with the removable sleeved cover element is thus easy to carry and be re-filled with new solutions.

A snivel suction apparatus includes a suction mechanism and an air extraction mechanism. The air extraction mechanism is connected to the suction mechanism. The air extraction mechanism includes a pump, a piston, a communicating tube, a first check valve and a second check valve. The piston is arranged on the pump. One side of the communicating tube is connected to the pump. The other side of the communicating tube is connected to the suction mechanism. The first check valve is arranged in the pump and at one side of the communicating tube. The second check valve is arranged on the pump.

A respiratory ventilator device is described herein. The respiratory ventilator device includes an inhaled air assembly, an exhaled air assembly, and a control system operatively coupled to the inhaled air assembly and the exhaled air assembly. The inhaled air assembly is coupled to a patient respiratory circuit and configured to channel a volume of inhalation air to the patient's lungs to assist in patient inhalation. The exhaled air assembly is coupled to the patient respiratory circuit and configured to remove air from the patent's lungs to assist in a patient exhalation. The control system is configured to operate the respiratory ventilator system in an inhalation mode and an exhalation mode.
