Heat-sealable chemical vapor-sensor bag

The present invention relates to a chemical vapor-sensor bag with an integrated sensor array to verify the presence of specific chemical vapors inside a sealed bag. In an exemplary embodiment, a device can be sealed within a vapor-sensor bag to allow the device to be transported to and tested for contaminants at the point of use by an end user of the device. In another exemplary embodiment, a device can be coupled to a gas port on a vapor-sensor bag to allow gas within the device to be tested for contaminants. In another exemplary embodiment, gas from a device can be streamed through vapor-sensor bag by coupling the device to a first gas port on a vapor-sensor bag and allowing gas to exit the bag through a second gas port.

An in-situ fecal specimen sampling device for stool tests, comprising: a sampling tube of a tube-like structure comprising an bottom with an opening; a sampling structure disposed inside the sampling tube is attached to the bottom of the sampling tube, and is an tube-like structure with a closed top end, an bottom end with opening and an stretchable soft body, which can insert a finger from the opening of the bottom outside the sampling tube and push forward and stretch the closed top end to beyond the sampling tube. The sample provider is able to collect the sample by placing the sampling structure onto the stool or inside the anus through the finger operated sampling structure by himself. All of the process can be finished during defecation process in-situ.

SELF-CONTAINED SAMPLING DEVICE FOR PROCESSING WHOLE BLOOD

A collection device is disclosed having a tubular housing detachably receiving a valved bulb reservoir at a first end thereof, the housing having a second end for dispensing fluids. The valved bulb reservoir has a sample capillary tube attached at one end thereof. The bore of the capillary is fluidically coupled to the valved bulb reservoir. The capillary is removed from the tubular housing to collect a sample in its bore, and is then replaced into the tubular housing. The contents of the valved tubular reservoir, which can be a buffer solution, a reagent, or other analytic fluid, or a gas, are then passed through the capillary bore to expel the sample and mix therewith in the housing. The sample product can then be dispensed from the tubular housing.

Processing Cartridge and Method for Detecting a Pathogen in a Sample

In one embodiment, a multiplex fluid processing cartridge includes a sample well, a deformable fluid chamber, a mixing well with a mixer disposed therein, a lysis chamber including a lysis mixer, an electrowetting grid for microdroplet manipulation, and electrosensor arrays configured to detect analytes of interest. An instrument for processing the cartridge is configured to receive the cartridge and to selectively apply thermal energy, magnetic force, and electrical connections to one or more discrete locations on the cartridge and is further configured to compress the deformable chamber(s) in a specified sequence.

PORTABLE URINATION WEIGHT MEASUREMENT DEVICE

A portable urination weight measurement device comprising: a holding unit for releasably holding a container, and a handle comprising a weight measurement unit coupled to the holding unit so as to allow the measure of a weight exerted on the holding unit; and a toilet flushable container having: a rim having a fold at a front side of the opening and a fold at a back side of the opening, each fold forming at rest an angle of less than 20, and a collar secured to the rim and comprising at least one fold at the front side of the opening forming at rest an angle of less than 20, the collar being of a rigidity such that increasing the angle of the collar fold to 180 increases the angle of the rim fold at the back of the opening to from 50 to 90.

Filter bag incorporating a device to facilitate the removal of a filtrate
10933355 · 2021-03-02 · ·

A filter bag comprising with a wall structure defining an inner volume with an opening. The wall structure extends from a bottom to the opening. A filter extends from the bottom toward the opening to separate the inner volume into a sample receiving compartment and a filtrate collection compartment. An orifice in the wall structure is in communication with the filtrate collection compartment, and a closure system has a closed state wherein access through the orifice is prevented and an open state wherein access through the orifice is permitted. The closure system can have a moveable part operative to selectively seal the orifice and a stationary part fixed to the wall structure with a separative limit therebetween. A fastening system can selectively retain a foldable portion of the wall structure against the wall structure to adjust the opening from an open state to a closed state.

Sample and reagent reservoir kits and liners with anti-vacuum feature

A pipetting reservoir kit includes a base, a disposable liner, and a lid. The disposable liner includes anti-vacuum channels on the bottom wall to prevent a pipette tip vacuum engaging the wall during aspiration. The groupings of anti-vacuum channels located on the bottom surface of the liner face upward into the basin that holds liquid samples or reagents. The groupings of anti-vacuum channels are spaced in an array 4.5 mm apart for a 384 pipetting head and 9 mm apart for a 96 pipetting head. The anti-vacuum channels also lower the required working volume for the liner and reduce liquid waste.

20210016287 · 2021-01-21 ·

The present invention involves a reinforced tubing structure that is particularly useful for reinforcing tubing that is present inside disposable bioreactor bags, including for example thermowell tubing.

Sequencing device

A method of preparing reagents includes inserting a cartridge into an instrument. The cartridge includes a plurality of reagent enclosures disposed in a cavity of the cartridge and exposing a port to an exterior of the cartridge. Each reagent enclosure includes a reagent container including a reagent and an internal cavity defining a compressible volume, an opening defined through the reagent container to the internal cavity. The method further includes connecting a plurality of fluid ports to the openings of the plurality of reagent enclosures; applying a solution through the fluid ports to at least partially fill the plurality of reagent enclosures; and cycling a pressure of the cavity, whereby for each of the reagent enclosures, during increasing pressure, the solution enters the internal cavity of the reagent container, combines with the reagent, and compresses the compressible volume, and during decreasing pressure, the compressible volume decreases and the reagent is ejected through the opening.
