Disclosed are methods and apparatus for determining analyte concentration in a sample such as bodily fluid. Systems and methods disclosed herein can also include a treatment dosing system to infuse or inject a treatment drug (e.g., insulin or glucose) and provide glycemic control. The dose of the treatment drug may be based on the concentration of th4e analyte or the average value for the concentration of the analyte and/or the rate of change of the value of the concentration of the analyte.

Bodily fluid sample collection systems, devices, and method are provided. The device may comprise a first portion comprising at least a sample collection channel configured to draw the fluid sample into the sample collection channel via a first type of motive force. The sample collection device may include a second portion comprising a sample container for receiving the bodily fluid sample collected in the sample collection channel, the sample container operably engagable to be in fluid communication with the collection channel, whereupon when fluid communication is established, the container provides a second motive force different from the first motive force to move a majority of the bodily fluid sample from the channel into the container.

Sterile transport, storage, and operation of fluid collection tubes in platelet-rich fibrin and platelet-rich plasma procedures. Sterile sample tube packages comprise a tray having a recessed cavity formed therein, one or more fluid collection tubes, and a cover. Each cavity houses a tube. A practitioner accesses a tube without contaminating the remaining tubes.

A biological fluid collection device that is adapted to receive a blood sample is disclosed. The biological fluid collection device includes a housing, a puncturing element transitionable between a pre-actuated position wherein the puncturing element is retained within the housing and a puncturing position wherein at least a portion of the puncturing element extends through the housing, and a cartridge removably connectable to a portion of the housing. After collecting a blood sample, the cartridge is removable from the housing and the cartridge is able to transfer the blood sample to a point-of-care testing device. The biological fluid collection device provides a closed system that reduces the exposure of a blood sample and provides fast mixing of a blood sample with a sample stabilizer.

The present invention relates generally to a sampling apparatus and a method for bodily fluids, and, more specifically, a blood sampling apparatus and a method for using the same. A blood collection system includes a housing having at least one open end, and an absorbent material positioned within the housing. The absorbent material has at least one end positioned proximate the at least one open end of the housing. A method of collecting blood samples includes positioning an absorbent material near a source of blood, holding the absorbent material with a housing, the absorbent material absorbing a volume of blood, and moving the housing and absorbent material to a position where the absorbent material can dry.

A system for confirmation of fluid delivery to a patient at the clinical point of use is provided. The system includes a wearable electronic device. The wearable electronic device has a housing; at least one imaging sensor associated with the housing; a data transmission interface; a data reporting accessory for providing data to the user; a microprocessor for managing the at least one imaging sensor, the data transmission interface, and the data reporting accessory; and a program for acquiring and processing images from the at least one imaging sensor. The system further includes a fluid delivery apparatus; and one or more identification tags attached to or integrally formed with the fluid delivery apparatus. The program processes an image captured by the at least one imaging sensor to identify the one or more identification tags and acquires fluid delivery apparatus information from the one or more identification tags.

Blood sample collection and processing system (1) using a tube (102) and a holder (104) is described herein. The tube (102) includes a plasma separation system (114) for converting a whole blood sample (129) into a plasma sample without using centrifugation. The plasma separation system (114) may comprise a filtration system such as a hollow fiber element (115). The tube (102) is thereafter placed in the holder (104) for analysis regarding the plasma. The results of the analysis may be displayed to the user via a display screen (134) to allow the user to determine whether the sample is sufficient for further use. Inasmuch as the analysis system (132) performs a rapid analysis of the plasma sample, the patient may still be present or in close proximity and if the sample is insufficient, the healthcare provider can take another whole blood sample (129), counsel the client regarding the blood sample (129), or examine the patient further.

A biological liquid collection vessel is adapted to contain a biological liquid to be centrifuged. The collection vessel has a vessel body having an open upper end and a closed lower end, a continuous wall, a target area at the upper end, and a solids area at the lower end that is connected to the target area. The target area is extended in length. In some embodiments, a volume capacity of both of the target area and the solids area are configured so that a red blood cell portion of the centrifuged biological liquid (e.g., blood) is substantially contained in the solids area, and the serum or plasma portion of the centrifuged biological liquid is substantially contained in the target area. Methods of and systems using the liquid collection vessels are provided, as are other aspects.

Disclosed are methods and apparatuses for determining analyte concentration in a sample such as bodily fluid. Systems and methods disclosed herein can also include a treatment dosing system to infuse or inject a treatment dose (e.g. insulin, dextrose, etc.) and provide glycemic control. The dose of the treatment drug may be based on the patient's calculated sensitivity to treatment dosing, for example. The dose of the treatment drug may be based on the concentration of the analyte or the average value for the concentration of the analyte and/or the rate of change of the value of the concentration of the analyte. Delivery of the treatment drug can be cut off if the determined analyte concentration indicates that continued delivery would be harmful to the patient.
