A funnel-shaped extension attachment is provided for a blood collection device. The attachment provides a larger area for collecting a fingertip blood sample from a patient than the collection device itself would otherwise provide. The funnel is preferably easily removable from the collection device after the blood sample is taken. Optional trenches running down one or more corners of the attachment may be used to encourage pulling blood drops from the finger tip through capillary action. A tube may also provide another location to encourage pulling blood drops from the finger tip through capillary action. The funnel attachment may be mated with the collection device at a point of manufacture, or separately shipped and installed over the collection device at a point of use.

A capillary cavity 19 and an inlet 13 protruding circumferentially outward from an axial center 107 are connected by a guide section 17 formed so as to extend circumferentially inward and on which a capillary force acts. A sample liquid collected from a leading end of the inlet 13 is transferred to a separation cavity 23. A bent section 22 and a recess 21 are formed at a connected section of the guide section 17 and the capillary cavity 19 so as to change the direction of a passage.

Devices and methods for withdrawing bodily fluid from a patient are disclosed herein. A handheld device configured in accordance with the present technology can include a housing having an opening, a skin-piercing assembly located at least partially within the housing, and an actuator movable relative to the housing along a deployment direction. The skin-piercing assembly can include a skin-piercing feature and a biasing member. The biasing member can be coupled to the skin-piercing feature to bias the skin-piercing feature along the deployment direction. Movement of the actuator along the deployment direction to a predetermined position can increase a load on the biasing member to at least a partially loaded state. Movement of the actuator along the deployment direction beyond the predetermined position can release the load on the biasing member so that the biasing member actively drives the skin-piercing feature along the deployment direction.

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.

An analyzing device having a microchannel structure includes a sample inlet and a guide section extending from the sample inlet toward an axial center. The analyzing device further includes a first cavity connected to the guide section and configured to measure a certain amount of a sample liquid, and a receiving cavity located adjacent to the first cavity and receiving the sample liquid. The analyzing device further includes a liquid reservoir formed between the sample inlet and the guide section and temporarily holds the sample liquid before being suctioned into the guide section. The sample liquid temporarily held in the liquid reservoir is transferred from the liquid reservoir to the guide section and the first cavity by a capillary force and transferred to the receiving cavity by a centrifugal force caused by rotating the analyzing device about the axial center.

A biological fluid collection device (10) that receives a sample (12) and provides flow-through blood stabilization technology and a precise sample dispensing function for point-of-care and near patient testing applications is disclosed. A biological fluid collection device of the present disclosure is able to effectuate distributed mixing of a sample stabilizer within a blood sample and dispense the stabilized sample in a controlled manner. In this manner, a biological fluid collection device of the present disclosure enables blood micro-sample management, e.g., passive mixing with a sample stabilizer and controlled dispensing, for point-of-care and near patient testing applications. Advantageously, a biological fluid collection device of the present disclosure includes an internal vacuum (28). In this manner, a biological fluid collection device of the present disclosure eliminates the need for additional vacuum creating components that must be connected to the biological fluid collection device during use.

Apparatuses, methods, and systems are disclosed for accelerated ergonomic collection of capillary blood. An apparatus and system include a blood collection module with a proximal portion including a vacuum generation chamber, a distal portion including a blood collection chamber, a concave mid portion including a pressure equalization channel configured to equalize reduced air pressure. The apparatus further includes a sealing surface to stably seal the blood collection module to the skin around a collection site and a slide latch actuated by a lengthwise sliding motion. Also included is a lancet carrier with linearly-arranged lancet strips to puncture rows of blood extraction slits in the collection site. The apparatus also includes an angled transfer port with a low-resistance non-microfluidic blood flow channel to a transfer module, then to a plasma separation module with a multilayer laminate and plasma separation membrane. Methods for accelerated ergonomic collection of capillary blood are disclosed.
