Abstract: An oxygen supply apparatus is configured to directly supply oxygen-containing gas to an user for inhalation while facilitating blood circulation of a specific portion of the user. The oxygen supply apparatus includes a power supply; an oxygen-containing gas source for providing the oxygen-containing gas; a gas catheter having one end thereof connected to the oxygen-containing gas source; an inhalator connected to the other end of the gas catheter; and a circulation facilitating device at least partially attached to the specific portion of the user. The circulation facilitating device includes a sonic oscillation circuit and a housing.

Abstract: The invention is a can-filter structure of an oxygen concentrator, which includes: a first can-filter having filter material; a second can-filter having filter material; and an outlet cover. The first can-filter includes an air inlet provided at the entrance side of the first can-filter and a first conical joint formed at the exit side of the first can-filter, wherein the first conical joint is hollow and at least one recess is provided on the outer surface thereof. The second can-filter includes a second conical joint formed at the entrance side of the second can-filter, wherein the second conical joint is hollow, and at least one engaging hook corresponding to the recess is provided on the inner surface thereof for coupling to the first conical joint. The outlet cover is provided at the exit side of the second can-filter and is coupled thereto by ultrasonic fusion.

Abstract: The invention is an assembly structure that allows molecular sieves and can-filters be fast assembled in an oxygen concentrator.

Abstract: A portable oxygen generating system comprises a reaction chamber having at least a first storage compartment for containing a first reacting substance and a second storage compartment for containing a second reacting substance, a dispensing mechanism operable to cause the first and second reacting substances to contact with each other so as to create a chemical reaction to produce an oxygen gas, and a gas outlet for delivering the produced oxygen gas. To use the system, the user pushes on a switch to initiate the production of oxygen.

Abstract: A respiratory mask comprises a mask body and a filter system. The filter system includes a replaceable filter cartridge accommodating a filtration material separable into a plurality of portions, and a filter chamber connected to the mask body and configured to receive one portion of the filtration material. To change the filtration material, a user removes a first portion of the filtration material from the filter chamber, and positions a second portion of the filtration material contained inside the filter cartridge.

Abstract: A respiratory testing system comprises a fluid chamber enclosing a fluid medium and having a flexible membrane deflectable by the application of a respiratory gas flow, a pressure sensor configured to sense a pressure variation of the fluid medium in response to a deflection of the flexible membrane, and a processing circuit configured to compute a respiratory flow data from a pressure variation of the fluid medium. The respiratory testing system may additionally include a breathing exercise unit configurable to execute a software program responsive to an input of the respiratory flow data.

Abstract: A tonometer includes a chamber containing a fluid medium and having a contact tip for contacting an eye surface, the contact tip having a flexible surface stretched by the fluid medium, a pressure sensor detecting a pressure variation of the fluid medium, a detecting mechanism determining whether the tonometer is correctly placed against the eye surface, and a processing circuit configured to treat electrical a signal received from the detecting mechanism.

Abstract: The present invention is a automatic sound blood measurement device, it output a blood sense signal to a micro-computer CPU to operate from a blood pressure and voltage signal transform interface circuit; then, the operation result signal of said micro-computer CPU through a sound mixer to generate a analog mix signal, and inform the patient by sound broadcasting method through a speaker, and in the mean time it also can show up on the display screen by digital method, and the patient can easily read the blood pressure and related function (such as systolic blood pressure, diastolic blood pressure, heart beating, and auxiliary medical sound reading) messages by hearing and seeing.
