摘要:
A drug dispensing-tracking device configured in the form of at least one of a cover, a sleeve, and a cap, and configured to connect with a drug-injection or storage device. The tracking device may comprise at least one or more of: an acoustic sensor, a vibration sensor, an optical sensor, an optical-navigation sensor, and a magnetic sensor, and any combination thereof. At least one sensor may be configured to produce at least one respective signal in response to sensing a vibration, a sound, light, movement, and a magnetic field, respectively, produced by the drug-injection device due to an activity of the drug-injection device.

To provide a method for calibrating a discharge volume of the pipette that enables accurate measurement of the discharge volume under arbitrary conditions, and to provide an apparatus therefor. The method including the steps of, setting a preset volume by the pipette that is actually used in a measurement (S1), sucking liquid that is actually used in the measurement into the pipette chip that is actually used in the measurement while aiming to be sucked the preset volume (S2), discharging the liquid sucked in the pipette chip onto a measuring apparatus (S3), determining an actual discharge volume of the pipette based on the weight measured (S4 to S6) and calculating a ratio between the preset volume and the actual discharge volume and correcting a sucking amount so as to bring the sucking amount to match an amount obtained by multiplying the preset volume by the ratio (S7 to S9).
摘要:
A container cleaner comprising a spray head, a travel limiter wherein the length the spray head may be depressed is limited by the location of the travel limiter, a starter rod wherein said starter rod is capable of being depressed by said spray head, a timing cartridge wherein the timing cartridge is capable of being opened for a selected period of time when the starter rod is decompressed and a fluid inlet. The further the spray head is depressed the longer the time duration the timing cartridge remains open and the longer the time duration of the pressurized spray is sprayed. The length the spray head may be depressed is dependent on the position of the travel limiter and he travel limiter may be positioned by rotating the spray head.

A fluid dispenser includes an adjustable dosing mechanism that permits adjustment of the amount of fluid to be dispensed. An adjustable dosing mechanism may be inserted into the dispenser in either a high dose orientation or a low dose orientation. The body further includes pair of dose adjusting flanges. When the adjustable dosing mechanism body is received into the dispenser in the high dose orientation, a relatively larger quantity of fluid product is dispensed. When the adjustable dosing mechanism body is received into the dispenser in the low dose orientation, a relatively smaller quantity of fluid product is dispensed.

A fixed-nozzle dispenser pump suitable for large doses has a downwardly-directed nozzle tip (32) and an outlet valve arrangement (4) in the nozzle (3). A blocking element e.g. ball (41) of the outlet valve (4) is biased back along a close-fitting tubular draw path (43) in the valve after dispensing, so as to draw product back out of the nozzle tip and prevent dripping. A further feature is subdivision of the nozzle tip and a flexible flap valve (35) blocking a resulting passage segment in the nozzle. This facilitates clearance of another nozzle passage (36) by the suck-back. A further feature is a membrane (24) across the front of the piston plunger, advanceable relative to the piston seal (231) by pressure on the plunger head (21). This helps accommodation of sucked-back fluid and enables a spot-dosing action.

A delivery device includes a durable housing portion (22) and a separable disposable portion (20) that selectively engage and disengage from each other. The disposable housing portion secures to the patient-user and may be disposed of after it has been in use for a prescribed period. Components that normally come into contact with a patient-user or with an, infusion medium, including a pump device, are supported by the disposable housing portion for disposal after the prescribed use, while the durable housing portion supports other components such as electronics for controlling delivery of the infusion medium from the reservoir and a drive device and drive linkage.
