Ventilatory assistance for treatment of cardiac failure and Cheyne-Stokes breathing

Method and apparatus for the treatment of cardiac failure, Cheyne Stokes breathing or central sleep apnea are disclosed. A subject is provided with ventilatory support, for example positive pressure ventilatory support using a blower and mask. Respiratory airflow is determined. From the respiratory airflow are derived a measure of instantaneous ventilation (for example half the absolute value of the respiratory airflow) and a measure of longterm average ventilation (for example the instantaneous ventilation low pass filtered with a 100 second time constant). A target ventilation is taken as 95% of the longterm average ventilation. The instantaneous ventilation is fed as the input signal to a clipped integral controller, with the target ventilation as the reference signal. The output of the controller determines the degree of ventilatory support. Clipping is typically to between half and double the degree of support that would do all the respiratory work. A third measure of ventilation, for example instantaneous ventilation low pass filtered with a time constant of 5 seconds, is calculated. Ventilatory support is in phase with the subject's respiratory airflow to the fuzzy extent that this ventilation is above target, and at a preset rate conversely.

Luminaires for illumination of outdoor panels

Luminaires for illumination of vertical surfaces of predetermined dimensions such as billboards or similar signs, the invention in several embodiments takes the form of reflector assemblies capable of directing light from a light source disposed within each of said luminaires either directly to the vertical surface or to refractive structures located on the luminaires for redirection of light to the vertical surface for even illumination of said surface with minimal light pollution from “spill” light. Lamps used in embodiments capable of providing asymmetrical light distributions are located toward one or the other of side portions and are preferably vertically oriented. A main reflector is curvilinear in conformation and functions in concert with a secondary reflector located directly behind the lamp to direct light onto desired portions of a vertical surface. Luminaires configured according to the invention also utilize side reflectance panels for light control and for maximizing light directed onto a vertical surface, said luminaires also preferably including refractive lens elements for redirection of light onto the vertical surface. The reflector assemblies of the invention are mounted within weather-tight housings, the refractive structures conveniently being disposed on or formed integrally with a transparent glass or plastic cover that completes the housing, said cover being located between the lamp and the vertical surface to be illuminated. Efficiencies occasioned by the present luminaires permit illumination of billboards and similar signs of standard dimensions with only two of the luminaires and with full and even illumination with minimal light spillage, a capability approached previously in the art only with a greater number of luminaires.

Method and device for monitoring controlling oxygen inhalation instrument

InactiveCN101121051AChange oxygen concentrationUninterrupted careRespiratorsData processing applicationsLower limitMicrocomputer
The present invention discloses a method and an installation of monitoring and controlling an oxygen inhalator. Under the control of a microcomputer, an upper limit and a lower limit of a patient blood oxygen saturation are set, and a preset flow velocity ratio is set for the oxygen inhalator. The oxygen inhalator is opened and supplied with oxygen at the preset flow velocity, after a period of time, the blood oxygen saturation inside the body of the patient who inhales oxygen is inspected, the flow velocity of a proportion electromagnetic valve which is in series in an gas path of the oxygen inhalator is regulated properly until the blood oxygen saturation is within a preset range. The apparatus not only has the characteristics of the oxygen inhalator and a monitor but also closely combines the oxygen inhalator and the monitor to realize an interaction. The apparatus provides monitoring of life sign parameters such as the blood oxygen saturation and can automatically change an oxygen inhalation flow velocity with the preset flow velocity range according to the timely collected changes of the patient life singe such as the blood oxygen saturation and accordingly a patient oxygen inhalation concentration is changed, then the patient life sign is improved.

Pharmaceutical composition for treating diseases of urinary system and method for detecting components thereof

The invention relates to a pharmaceutical composition for treating diseases of the urinary system and a method for detecting components thereof. The pharmaceutical composition comprises the components of desmodium styracifolium, corn silk, pyrrosia lingua, herba abri, tuckahoe, herba plantaginis, lygodium japonicum and rhizoma imperatae. The detecting method comprises the following steps: taking the pharmaceutical composition as the sample solution; taking a herba abri control medicine as the control medicine solution; and absorbing the two solutions, respectively dropping on the same silica gel G thin-layer plate using sodium carboxymethyl cellulose as the adhesive, developing by using n-hexane-ethyl acetate as the developing agent, taking out, drying in the air, spraying a vanillina-sulphuric acid solution, and heating until the spots become clear. The pharmaceutical composition can be used for hygropyrexia of bladder, pyretic stranguria and stranguria caused by urinary stone, urinate ache, urinary tract infection, lithangiuria and nephritic colic. The invention has the advantages of low cost of preparation technique and detecting technique, and easy processing, reduces the heating time of the drugs and is suitable for wide application in clinical treatment.
