A container assembly is disclosed including an outer container, a hollow inner member, and a closure. The outer container has a closed bottom, an open top, and a sidewall extending therebetween. The hollow inner member is disposed within the outer container and has an inner surface defining at least one capillary channel. The inner member includes a first end adjacent to the open top of the outer container and has an outer periphery seated against the sidewall of the outer container. The closure has a proximal end and a distal end. The closure proximal end is seated at least partially within the first end of the inner member to seal the outer container and inner member and define a fluid collection chamber. The closure distal end defines a recessed area shaped to direct fluid under capillary action to the at least one capillary channel in the inner member.

A syringe-based device includes a housing and an actuator mechanism including a first member and a second member. The first member includes a syringe body and a plunger, the plunger being movably disposed within the syringe body. The second member includes a second member plunger seal and a valve operably and selectively coupled to the second member plunger seal such that the valve is positioned proximal of the second member plunger seal. The device also includes a first fluid reservoir and a second fluid reservoir. The device transitions from a first configuration to a second configuration in which the first type of fluid is expelled from the first fluid reservoir, to a third configuration in which the second type of fluid is expelled from the second fluid reservoir through the valve.

A sample holder for collecting a liquid sample, such as blood. The holder can include a vessel, a conduit having a proximal end extending from the vessel and a distal end positioned in the vessel, and a cap configured to engage with the vessel and create pressure to move a liquid sample in the conduit to move from the proximal end to the distal end. The vessel can include a fluid pathway to vent fluid from the vessel as the liquid sample is moved from the conduit into the vessel, and the cap can seal the fluid pathway closed. A desiccant can be used to support the conduit in the vessel and dry a blood sample during storage.

Disclosed is an attachment mechanism that may be used to attach a component to a particular location on a tube in a blood sampling-blood pressure monitoring system by a user. The attachment mechanism may include a piercing feature. The piercing feature may be used to pierce the tube to attach the component to the particular location on the tube of the blood sampling-blood pressure monitoring system selected by the user.

Disclosed is a tubing system for use in a blood sampling-blood pressure monitoring system. The blood sampling-blood pressure monitoring system may include a control valve, a reservoir with a plunger, a sampling site, and a blood pressure transducer for measuring the blood pressure of a patient. The tubing system may comprise: a plurality of flexible tubing sections and a plurality of rigid tubing sections. The plurality of rigid tubing sections and flexible tubing sections may be interlinked with one another between the patient and the blood pressure transducer for the blood pressure measurement of the patient.

The invention provides devices that improve tests for detecting specific cellular, viral, and molecular targets in clinical, industrial, or environmental samples. The invention permits efficient detection of individual microscopic targets at low magnification for highly sensitive testing. The invention does not require washing steps and thus allows sensitive and specific detection while simplifying manual operation and lowering costs and complexity in automated operation. In short, the invention provides devices that can deliver rapid, accurate, and quantitative, easy-to-use, and cost-effective tests.

A sample collection kit is described for ensuring positive sample identification. The sample collection kit includes a sample container configured to hold a biological sample. The sample container has a lower end, an upper end, a sidewall that extends from the lower end to the upper end, and an identifier disposed along the sidewall. The identifier includes information encoded therein related to the sample container and the sample. The kit includes a sample container holder. The sample container holder has a bottom end, an open top end, a sidewall, and a window in the sidewall. The window is positioned in the sidewall of the container holder such that when the collection tube is inserted inside the sample container holder, the identifier of the sample container is aligned with window of the sample container holder.

Provided are a packaging container, a blood test kit, and a blood analysis method, by which sealability of a collected liquid specimen is made to be compatible with easiness of extraction.

Provided is a packaging container including a bag main body portion which has a first surface and a second surface and has an opening portion; and a tongue piece portion which is formed to be continuously extended from the first surface, in which the bag main body portion and the tongue piece portion have an aluminum vapor-deposited layer on an outside thereof, the packaging container further including an adhesion portion which is provided on the second surface to be spaced from the opening portion; and a folded-back portion which is provided between the adhesion portion and the opening portion to fold back the tongue piece portion to the opening portion side, in which the following relational expression is satisfied in a case where a length of the tongue piece portion is a, a length from the opening portion to the folded-back portion is b, and a length from the folded-back portion to the adhesion portion is c. Furthermore, provided are a blood test kit containing this packaging container, and a blood analysis method using this blood test kit.

Systems and methods for collecting blood and other liquid samples. A sample holder may include a cap and porous element arranged to receive a blood or other liquid sample. The porous element may be stored in a sealed container, e.g., immediately after blood sample collection, and the sample dried while sealed in the container.
