Abstract: The laboratory device includes an elongated handle with ergonomic grips. The device has a center recess for a rod to slide or rotate. The blade head attaches at the distal end of the elongated handle. The rod has geared teeth that interact and mesh with the gears on the blade head allowing the user to manipulate the angle of the blade head via rod. The rod in the proximal position of the handle is disposed at an acute angle relative to the longitudinal axis of the handle such that the blade head and handle are positioned for insertion into and removal of a tissue culture vessel. When the rod is moved distally or rotated the blade head position is disposed perpendicularly, acute or obtusely in relationship to the longitudinal axes of the handle such that the blade head provides optimal raking opportunities for the device to collect cell colonies.

Abstract: A drying expiratory limb of a breathing circuit is provided that is configured to increase or optimize drying of a gas to reduce or prevent condensation. The drying expiratory limb can include a wall that is at least partly made of a breathable material configured to allow transmission of water vapor but substantially prevent transmission of liquid water. The wall includes first and second openings in the wall, the openings respectively configured to receive a gas at a first temperature and a first relative humidity and to allow the gas to exit having a second temperature and a second relative humidity. The drying expiratory limb can be configured to tailor the temperature drop of the gas along the wall to maintain a relative humidity within a targeted range and/or to maintain the gas temperature above its dew point temperature.

Abstract: A surgical mask gripper covering nose apex, ala and mouth of a person is disclosed. Gripper is designed to enhance the flow of air through the mask filter and restrict the flow of air leaking through the periphery of the surgical face mask. Gripper covering the contours of nose apex and ala creates a tight seal between face skin and surgical mask. Low profile of gripper around nose allows a person to wear safety or eye glasses without any interference. Tight seal forces inhaled and exhaled air through the surgical mask filter thereby improving the particulate filtering efficiency and eliminate the fogging of safety glasses.

Abstract: Embodiments relate to systems and methods for gas delivery for personal medical consumption having safety features. A hydrogen or oxygen gas delivery system herein can include electrolytic cores performing electrolysis-based reactions, and obtain free hydrogen (H2) gas for collection and delivery to a user. In aspects, the electrolytic core(s) can be scaled to produce a sufficient amount of hydrogen (H2) or oxygen (O2) gas so that the user can ingest that gas directly, without a need for storage. The system can be portable, and configured with a delivery tube for transmitting hydrogen or oxygen gas to a user. While safety risks are generally minimal, the system can be configured with sensors to detect fault conditions or hazards such as combustion or overpressure, which can only be caused by deliberate user action to expose gaseous products to flame or spark, and even then would not be likely to trigger violent combustion.

Abstract: A valve assembly attached to a capacitor such that pressurizing the capacitor to a first positive pressure threshold induces the valve assembly to open, the pressurized air is released to the patient, and then as the pressure in the capacitor drops to a second pressure threshold the valve closes and the capacitor begins to build pressure until the first positive pressure threshold is achieved and the process repeats. Relative to the valve assembly and integrated therein, is an incrementally adjustable index knob to vary the rate of a biasing force performing work against the actionable valve face of the diaphragm functional surface to set the performance of the valve assembly, thereby increasing the potential for correct operation across a range of oscillating rates supporting a broad spectrum of patient therapies and types.

Abstract: A garment and method for targeted water weight-loss of a user. The garment may be a typical article of clothing; however, heat trapping agents are applied to the garment, particularly on the inside of the garment so as to make contact with the skin causing increased perspiration of the user at the location where the heating trapping agent contacts the skin. The heat trapping agent can be applied to the garment at desired locations and with a desired pattern to increase the efficiency of perspiration, and therefore, water weight-loss, Preferably, the heat trapping agent is print material with a stretch additive.

Abstract: A patient ventilator system includes a patient delivery circuit having an inspiratory section that delivers an inspiratory gas flow to a patient and an expiratory section that receives expiratory gas flow from the patient, wherein a bidirectional blower motor drives the inspiratory gas flow in the inspiratory section and controls the expiratory gas flow in the expiratory section.

Abstract: Medical tubes and methods of manufacturing medical tubes. The tube(s) may be a composite structure made of two or more distinct components that are spirally wound to form an elongate tube. For example, one of the components may be a spirally wound elongate hollow body, and the other component may be an elongate structural component also spirally wound between turns of the spirally wound hollow body. The tube(s) need not be made from distinct components, however. For instance, an elongate hollow body formed (for example, extruded) from a single material may be spirally wound to form an elongate tube. The elongate hollow body itself may in transverse cross-section have a thin wall portion and a relatively thicker or more rigid reinforcement portion. The tube(s) can be incorporated into a variety of medical circuits or may be employed for other medical uses.
