  • Publication number: 20060242037
    Abstract: An apparatus and a method for assisting the marketing in which a service provider acts as proxy to send messages to healthcare people, as customers, who have met preset conditions, out of the totality of customers, and in which the healthcare people, who have received the messages, approve an MR of a particular pharmaceutical manufacturing company, so that the number of healthcare individuals, as customers, may be increased without the MR of the particular pharmaceutical manufacturing company visiting the premises of the healthcare people, and so that messages may be exchanged between the MR and the healthcare people. An MR of the main office of a pharmaceutical manufacturing company, supervising MRs in charge, is able to send messages to the healthcare individuals, as customers, in the name of the MR of the main office or the MR in charge, depending on the message sorts. Each participating company is able to increase the number of customers efficiently.

  • Publication number: 20050261997
    Abstract: Processing requests for financial-related transactions. Upon receiving a communication from a caller, wherein the communication includes a request for a particular financial card, information is obtained from the customer for use in processing the request. A first set of criteria related to the information is evaluated to determine if the request involves potential fraud. Based upon the evaluation of the first set of criteria, a second set of criteria related to the information is selectively evaluated to determine if the request involves potential fraud. An indication of the evaluation is output and used to determine whether to issue the requested financial card.

  • Patent number: 5906435
    Abstract: A rotary drum mixer mixes product matter in a particulate form. A scoop section for the mixer has scoop blades which are radially enclosed by a peripheral wall which rotates with the drum. A stationary hood includes an outer face portion which covers the end wall of the scoop section and a peripheral portion which covers the peripheral wall of the scoop section, but neither the outer face portion nor the peripheral portion of the stationary hood contact product matter. The scoop blades are relatively flat and are angled into the direction of rotation. A back section is also included for the scoop blades. A seal assembly is positioned toward the inner diameter of the scoop blades and biases radially outward. The seal assembly may alternatively be positioned at the outer diameter of the scoop section, and/or the seal member may alternatively be biased radially outward. An inflatable bladder is used to radially bias the seal member against a hoop.

  • Patent number: 5395321
    Abstract: In an infusion apparatus for use in the medical field, a peristaltic pump mechanism pumps an infusion fluid including medication through an administration tube toward a patient. A clock powered independent of the apparatus counts a predetermined unit time. A CPU accumulates data representing an incremental unit of fluid of the infusion fluid delivered by the pump mechanism to measure an accumulated infusion fluid volume each time the clock counts the unit time. Data as to the current accumulated infusion fluid volume is stored in a second storage section of a RAM. Each time the clock counts the unit time, data representing the accumulated infusion fluid volume stored in the second storage section is written to a ring buffer in the RAM, so that the ring buffer stores data representing a plurality of accumulated infusion fluid volumes in one-to-one correspondence with a plurality of times at which the plurality of accumulated infusion fluid volumes were measured.

  • Patent number: 5370612
    Abstract: A slit disk having a hole at a specified portion of its flat surface and a plurality of slits at regular intervals at a peripheral portion thereof is mounted to a shaft of an infusion pump. A controller clears a live band determination counter based on a light detection signal from a sensor when the hole is detected, and increments the count value of a live band determination counter when an side edge of one of the plurality of slit is detected. When the count value of the live band determination counter falls within "10" to "24" or "0" to "2", it is determined that the infusion pump is in a live band, and the count value of the live band counter is incremented. Thus an operation amount of the infusion pump in the live band is detected to measure a fluid delivery rate taking a dead band into account.

  • Patent number: 5312334
    Abstract: A peristaltic pumping apparatus has a misloaded-tube detector. The detector is constituted of a pair of pressure sensors and a CPU. The pressure sensors are located on both sides of a fluid propelling portion onto which an IV tube containing a solution is loaded. The detector detects a tube misloading by making use of pressure which is applied to one pressure sensor when the tube is displaced onto the pressure sensor and is forced against it by the closing of a door. Each sensor consists of first and second electrodes spaced from each other, a pressure-resistive conductive element attached to the first electrode and spaced from the second electrode and capable of connecting thereto, and a resistor connected to the first and second electrodes. The CPU judges from a resistance value of the pressure sensor as to whether the tube is properly loaded or misloaded or whether the pressure sensor is in an operative state.
