  • Patent number: 7338634
    Abstract: A quantitative fecal examination apparatus includes a fecal collector removably mounted on a container base, having the fecal collector provided with a suction portion for sucking a fecal specimen into the collector and then the fecal specimen is disposed into the container base for examination test or for sucking the fecal specimen for further laboratory test including microscopic inspection, and having a quantitative design in the examination apparatus for collecting the fecal sample in a pre-set quantity for more precise examination.

  • Publication number: 20060254105
    Abstract: A hospital identification band includes a wrist band adapted to be wrapped on a patient's arm or wrist, a label having the patient's data written or printed on the wrist band; and a control sleeve formed on a head portion of the wrist band for adjustably jacketing a tail strip of the wrist band through the control sleeve to form a loop wrapping the patient's arm or wrist, having adhesive coated on an inside surface of the control sleeve, whereby upon a proper adjustment of the tail strip in the control sleeve for snugly fastening the wrist band around the patient's arm or wrist, the control sleeve is firmly pressed to bond the tail strip with an adhesive-coated inside surface of the control sleeve, and an insertion of the tail strip through a concealing slot transversely formed in the head portion of the wrist band to conceal the tail strip beneath the wrist band, thereby easily fastening an identification band on a patient or wearer.

  • Publication number: 20040180427
    Abstract: A medical apparatus includes a sampling and inoculating device detachably mounted in a container; having a suction portion formed on the sampling and inoculating device for sucking a liquid specimen which is then discharged into the container for storage or transport, a swabbing head detachably secured to a lower portion of the sampling and inoculating device for picking up the specimen and also for primarily inoculating the specimen onto a culture dish for a streak procedure, and an inoculating head formed on the lower portion of the sampling and inoculating device for subsequently diluting and separating the bacteria from the zone as streaked by the swabbing head for well inoculating and culturing the bacteria in order to identify the bacteria for a reliable medical treatment.

  • Patent number: 4849173
    Abstract: An excrement examination unit includes a handle member having an elongate stirrer inserted in a housing. Fecal sample is picked up by the stirrer and dissolved into a medical saline solution by shaking the stirrer. Fecal solution is downwardly discharged and absorbed on a liquid-penetrable filter so that a simple occult blood test can be conducted by poking a test paper onto the filter through a slot formed in the housing to prevent a fecal contamination. Fecal solution is next downwardly discharged into a test tube for further laboratory examination.
