An elimination-absorber monitoring system addresses diaper-monitoring problems with a unique, low cost, multi-layer disposable sensor structure that absorbs small volumes of urine, yet allows most urine volume to flow unimpeded through it, and into the diaper below. When connected with a reusable, miniature monitor/indicator unit, the sensor presents a clear and on-going change of measurement condition upon experiencing a rapid influx into the diaper of a significant volume of urine, and/or upon a significant reduction in the available absorbency of the diaper's top surface. The sensor additionally provides recessed, protected elements for similarly presenting a clear and on-going change in measurement condition upon experiencing the presence of fecal matter. Further provided is the monitor unit employing narrow, widely-spaced, fast rise-time, fast transition-time pulses for conductivity measurement and alarm activation. The monitor and sensor are interconnected and attached to a diaper by particularly effective and unique means, and the monitor is equipped with a highly intuitive and convenient control interface, as well as improved assemblies for the transmission of audible and visual alarm indications. Also described is a convenient test-strip device which, when connected to the monitor/alarm unit of the system, can selectively simulate either a soiled or unsoiled elimination-absorber/sensor for test, caregiver-training or demonstration purposes.

Abstract of Disclosure Devices, systems and methods are provided for piercing the skin, accessing and collecting physiological sample therein, and measuring a characteristic, e.g., an analyte concentration, of the sampled physiological sample. The subject devices are in the form of a test strip which include a biosensor and at least one skin-piercing element which is a planar extension of a portion of the biosensor. At least one fluid pathway resides within a portion of the biosensor and within the skin-piercing element. The skin-piercing element has a space-defining configuration therein which acts as a sample fluid pooling area upon penetration into the skin. Systems are provided which include one or more test strip devices and a meter for making analyte concentration measurements. Methods for using the devices and systems are also provided.

A multilayer test strip and method of using the test strip for determining concentration of HDL cholesterol in a whole blood sample. The inventive test strip includes a two-stage blood separation mechanism, including a first glass fiber matrix which separates most of the blood cells and an adjacent, second matrix preferably also containing glass fibers that separates the remainder of the blood cells. The second layer also precipates and retains non-HDL cholesterol, thereby providing plasma that is substantially free of red blood cells and substantially free of non-HDL cholesterol to a reaction layer. Precipitation and retention on non-HDLs takes place by a vertical or dead-end filtration in a single layer. The reaction layer produces a color, the intensity of which is proportional to the concentration of HDL cholesterol in the blood sample which is applied to the test strip. Advantageously, the inventive test strip is a vertical flow device, which can be made more compact and operates more efficiently than a lateral flow device.

The invention provides a device for stool sampling and occult blood self-detection. The device comprises a cover, a main container, a stool sampling rod, a stool sampling rod guide channel, a stool dissolution tank, a stool liquid filter pipe, a communication pipe and a test strip detection tank. The stool sampling rod is fixed to the cover or is not fixed to the cover. A top end of the stool sampling rod is fixed to a top wall of the interior of the cover. The stool sampling rod is inserted into the stool sampling rod guide channel. The bottom of the stool liquid filter pipe is connected to the bottom of the test strip detection tank by the communication pipe. The device realizes quantitative acquisition, dissolution, filtration and immune test strip detection of a stool sample, does not produce liquid leakage in storage, conveying and detection, realizes stool sampling and occult blood self-detection in a single cycle, avoids stool direct viewing, is convenient for carrying, operation and cleaning, and is suitable for stool occult blood self-detection carried out by an average adult at any time or place. The device has a reasonable design, a simple structure and a low production cost, is convenient for operation, avoids stool liquid opening, realizes one-step detection after stool sampling, and is clean and safe.

This invention provides a device for detecting an analyte in a liquid sample, comprising a cup body (7), a lid (1) and a base (15), wherein, said the cup body (7) comprises a liquid storage chamber (9) and a test strip groove locating in one side of liquid storage chamber, the storage chamber (9) and the test strip groove communicates each other through a small hole in the bottom of liquid storage chamber, the test strip groove is configured with a test strip plate, said lid being able to seal the opening of the cup tightly, said opening of cup being directly connected with the liquid storage chamber.

A device for determining the presence and/or quantity of one or more analytes in a sample of human body fluid has a container for receiving a sample of body fluid, with an interior that is delimited by a base and by a circumferential surface. It further comprises at least one test strip and a holding element for receiving and holding the one or more test strips. The holding element is designed such that it has a shape corresponding and adapted to the peripheral circumferential surface of the container. The device further comprises an elongate sampling element having an absorbent sampler that takes up the sample of body fluid and by means of which the sample of body fluid is transferred into the container. Further, the base of the container has a central elevation via which the sample of body fluid can be conveyed from the sampler, by compression thereof on the elevation, to the at least one test strip.

A test strip for conducting a lateral flow assay for detection of an analyte in a sample that contains cells and fluid is provided, as well as methods for making and using the test strip. This test strip is commercially usable, for example, in a diagnostic device at a point of care for detection of analytes in whole blood.

The invention discloses a testing strip packing box. The testing strip packing box comprises a box body and a box cover, wherein an outlet and at least one notch are formed in the box body, the notches allow testing strips to be pushed out, an elastic pressing device used for pressing the testing strips is arranged in the box body, and the two ends of the elastic pressing device make contact with the inner wall of the box body and the contact face of each testing strip respectively so that each testing strip can be sent to the waiting position of the outlet. A transfer plate is arranged between the elastic pressing device and the testing strips, and the elastic pressing device presses the testing strips through the transfer plate. The packing box further comprises a testing strip pushing part which can slide along a side wall of the box body, and the testing strip pushing part is detachably connected with the side wall, provided with the notches, of box body. Protruding blocks and buckles are arranged on the testing strip pushing part, the testing strip pushing part is connected with the side wall, provided with the notches, of the box body in a clamped mode through the buckles, and the protruding blocks extend into the box body through the notches to push the testing strips out of the outlet. According to the testing strip packing box with the structure, a user can take out the testing strips without making contact with the testing strips by hand when using the testing strip packing box, and therefore the testing strips are prevented from being stained.
