Abstract: An elliptical drive mechanism and a steering mechanism, applicable to velocipedes in general, is disclosed. Sliding blocks are capable of sliding along guide rods such that the sliding blocks are movable along the guide rods in an elliptical trajectory while the sliding blocks are simultaneously capable of driving cranks to cause a chain to drive a ratchet for driving a rear wheel. A steering mechanism for velocipedes in general is disclosed. The steering mechanism allows leftward or rightward movement of the handlebar to produce rotation of the rear wheel fork and corresponding turning of the rear wheel.

Abstract: A breathing system is provided that employs a reservoir for holding oxygen or an oxygen and medicine mixture while the patient is not inhaling. The reservoir generally prevents waste and reduces cost and helps prevent the patient from re-inhaling the previously exhaled gases.

Abstract: A nasal cannula is provided that employs a left tube and a right tube wherein at least a portion thereof is made of a resilient and compliant material that elongates in response to a tensile load applied thereto. The contemplated tubing material will continue to supply a predetermined amount of oxygen to the patient if elongated, i.e., the elongated tube will not substantially constrict air flow.

Abstract: A luer connector is provided having a first member that includes an end face with a reflective material that does not cover the entire end face wherein the first member is selectively rotatable to align the reflective portion with sensors of the medical instrument. The first member is adapted to freely rotate within a second member that is used to connect the first member to the medical instrument.

Abstract: A plunger-less syringe, method of manufacture and system of use is disclosed wherein the syringe includes a barrel that has an interior receptacle for receiving a quantity of blood. The syringe has at least one filter that controls fluid flow within the syringe. The syringe may be fabricated from a material that prevents diffusion of the gas from the blood. Different syringes may comprise different fluid flow characteristics. In addition, the components of the syringe may include indicia so a syringe having particular characteristics can be selected for patients with different blood pressure.

Abstract: A plunger-less syringe and method of use are disclosed. The syringe includes an outer housing fixedly attached to an interior receptacle for receiving a quantity of blood. The syringe has a vent that allows air to escape from the receptacle as blood flows therein. The vent can include a filter for use in preventing blood from exiting the interior receptacle. A vent cap is provided having a recess for mating with a syringe having a plunger, wherein blood flow into the receptacle can be controlled. A plurality of the plunger-less syringes can be packaged in a container, wherein the blood pathway of the syringes is sterilized and without having any exterior sterile packaging.

Abstract: A splash shield for use in wound irrigation is provided. The splash shield includes at least one outlet area located along its rim so that irrigating fluid may flow from the splash shield. The splash shield is preferably oval-shaped with a substantially flat top adjacent to which is a receiver unit. The outlet area can be formed, for example, by contoured portions or by a generally V-shaped opening, each able to define a channel to enable the escape of fluid from the splash shield. The splash shield may be used in tandem with a syringe having a tip that is positioned in the receiver unit. Additionally, a basin can be provided for use during wound irrigation. The basin includes indentations to accommodate placement of a portion of the human body within the basin and an exit portion such that fluid in the basin can move in the basin to the edge of a table, bed, gurney or the like.

Abstract: A system for dispensing medication includes: a medicine canister that contains medicine to be dispensed, an actuator that houses the medicine canister and an adapter assembly that allows for obtaining information. The adapter assembly includes a connector assembly and an electronics module. The connector assembly connects to the medicine canister. The electronics module obtains information related to patient usage of medicine from the medicine canister. In another embodiment, a method for using the same electronics module with first and second medicine dispensing apparatuses, including a first medicine canister and a second medicine canister, is provided. The first medicine canister contains first medicine and the second medicine canister contains second medicine. First information, related to dispensing the first medicine, is stored with the electronics module joined to the first medicine dispensing apparatus.

Abstract: A system for collecting patient respiratory information includes a base unit and a removable mouthpiece unit. The mouthpiece unit includes sensors that sense parameters of a patient's breath when the patient blows into the mouthpiece unit. The base unit receives and processes the information from the mouthpiece unit and stores it in chronological fashion for later analysis by a physician. The mouthpiece unit includes a memory for storing identification information for a patient who has been assigned the mouthpiece unit. When the mouthpiece unit is inserted into the base unit, the base unit reads the identification information from the mouthpiece unit and stores all measurement information in association therewith. In this manner, a single base unit can be used to collect information for a plurality of different patients without creating confusion as to which measurement results correspond to which patients.

Abstract: A respiratory system drug applicator for a patient is disclosed which may include a number of features to enhance the administration of the aerosolized drug to the patient. For instance, an adjustable flow regulator may be utilized which regulates the air flow during inhalation by the patient (during which the aerosolized drug is also administered to the patient's respiratory system), and thus affects the patient's breathing pattern. Moreover, a distensible drug reservoir which changes shape during inhalation and exhalation by the patient may be utilized. This may be used to provide biofeedback to the patient regarding the patient's breathing pattern.

Abstract: A syringe device for obtaining a gas-free blood sample has a tubular body connected to an hypodermic needle. The tubular body receives a resilient sealing member operatively connected to a plunger rod. The sealing member and plunger rod have a vent formed longitudinally therealong to provide a passageway for the purge of air as an interior chamber of the tubular body is filled with blood. The passageway is covered with an hydrophobic filter allowing the passage of air until such time as blood completely contacts the filter, at which time blood cannot cross the hydrophobic filter. The interior chamber containing the blood sample is then purged of all air.
