[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This application claims priority to U.S. Provisional Application Serial No. 62 / 805,398, filed on February 14, 2019, entitled “CAPILLARY COLLECTOR WITH ROTATABLE CONNECTION,” the entire disclosure of which is incorporated herein by reference. Technical Field
[0003] The present disclosure generally relates to a device for obtaining a biological sample. More specifically, the present disclosure relates to an integrated finger-based capillary blood collection device that can pierce and squeeze a finger, collect, stabilize, and dispense a blood sample in a controlled manner. Background Art
[0004] Devices for obtaining and collecting biological samples (e.g., blood samples) are commonly used in the medical industry. One type of blood sampling commonly performed in the medical field is capillary blood sampling, which is commonly used to collect blood samples for testing. Certain diseases (e.g., diabetes) require regular testing of the patient's blood to monitor, for example, the patient's blood sugar level. In addition, test kits (e.g., cholesterol test kits) typically require blood samples for analysis. The blood sampling procedure generally includes pricking a finger or other suitable body part in order to obtain a blood sample. Typically, the amount of blood required for such tests is relatively small, and a small puncture wound or incision can usually provide enough blood for these tests. Various types of lancet devices have been developed for piercing the patient's skin to obtain a capillary blood sample from the patient.
[0005] Many different types of lancet devices are available for purchase by hospitals, clinics, doctor's offices, etc., as well as individual consumers. Such devices typically include a pointed member (e.g., a needle) or a sharp-edged member (e.g., a blade) for forming a quick puncture wound or incision on the patient's skin to provide a small amount of blood to flow out. Many people often find it physically and psychologically difficult to prick their own fingers with a handheld needle or blade. As a result, lancet devices have evolved into automatic devices that puncture or cut the patient's skin when a trigger mechanism is actuated. In some devices, the needle or blade remains in a standby position until it is triggered by a user, who may be a medical professional or the patient himself who is responsible for drawing blood from the patient. When triggered, the needle or blade punctures or cuts the patient's skin, such as the skin on a finger. Typically, a spring is incorporated into the device to provide the "automatic" force required to puncture or cut the patient's skin.
[0006] One type of contact-activated lancet device is U.S. Pat. No. 9,380,975, which belongs to the assignee of the present application, Becton Dickinson, and is characterized in that the puncture or cutting element automatically pops out and retracts from the device. The lancet device includes a housing and a lancet structure having a puncture element. The lancet structure is arranged in the housing and is suitable for moving between a holding or pre-actuated position in which the puncture element is held in the housing and a puncture position in which the puncture element extends through the front end of the housing. The lancet device includes a drive spring arranged in the housing for biasing the lancet structure toward the puncture position, and a retaining seat that resists the bias of the drive spring to retain the lancet structure in the retracted position. The retaining seat includes a pivot rod that interferes with the lancet structure. An actuator in the housing pivots the rod, thereby moving the lancet structure toward the rear end of the housing to at least partially compress the drive spring and release the rod from the interference engagement with the lancet structure. The received blood sample is then collected and / or tested. The test can be done via a point-of-care (POC) testing device, or it can be collected and sent to a testing facility.
[0007] Currently, the capillary blood collection workflow is a complex, multi-step process that requires a high level of skill. The multi-step nature of the process introduces several variables that can lead to sample quality issues, such as hemolysis, insufficient sample stability, and microclotting. Using a lancet device to obtain a blood sample results in several variables that affect the collection of a capillary blood sample, including but not limited to keeping the lancet stationary during testing, obtaining adequate blood flow from the puncture site, adequately collecting blood, preventing coagulation, etc. Some of the most common sources of process variability are: (1) inadequate cleaning of the blood collection site and removal of the first drop of blood, which can potentially lead to sample contamination; (2) inconsistent puncture location and depth, which can potentially lead to insufficient sample volume and a large proportion of interstitial fluid; (3) inconsistent squeezing technique and excessive pressure near the puncture site to facilitate blood extraction (e.g., milking), which can potentially lead to sample hemolysis; (4) variable transfer interfaces and collection techniques that can potentially lead to hemolysis or sample contamination; and (5) inadequate mixing of the sample with the anticoagulant, which can potentially lead to microclotting.
[0008] Therefore, there is a need in the art for a device that can pierce and compress a finger, collect a sample, stabilize the sample, and subsequently dispense the sample in a controlled manner. There is also a need in the art for a device that simplifies and streamlines capillary blood collection by eliminating workflow variability that is often associated with poor sample quality, including hemolysis and microclotting. There is a further need in the art for closed system collection and transfer that eliminates blood exposure and device reuse. There is also a further need in the art for a device that: (1) introduces flexibility in adapting to different capillary collection and transfer containers; (2) has the ability to produce high quality uniformly mixed / stabilized capillary blood samples; (3) has the ability to produce onboard plasma from capillary plasma samples; (4) has the ability to collect large capillary blood samples (>50-500 μL) with reduced pain; (5) contains a unique sample identifier that is paired with patient information at the time of collection; (6) has the ability to collect capillary blood and perform onboard diagnostics; (7) has multiple collection ports to collect blood samples into different containers with the same or different anticoagulants. Summary of the invention
[0009] The present disclosure relates to a device for obtaining a biological sample, such as a capillary blood collection device, which meets the above needs and has the ability to pierce and squeeze a finger, collect a sample, stabilize the sample, and then dispense the sample in a controlled manner. The device also simplifies and streamlines capillary blood collection by eliminating the workflow variability commonly associated with poor sample quality (including hemolysis and microclotting).
[0010] The present disclosure includes a self-contained and fully integrated finger-based capillary blood sampling device having the ability to puncture, collect and stabilize large-volume capillary blood samples (e.g., up to or in excess of 500 microliters). The device simplifies and streamlines large-volume capillary blood sampling by eliminating workflow steps and variability typically associated with poor sample quality, including hemolysis, microclotting, and patient discomfort. The device includes a retractable puncture mechanism capable of puncturing a finger and an associated blood flow path that ensures capillary blood adherence and transfer from the punctured finger site to a collection container. The device also includes a retainer that can be cyclically squeezed to stimulate (i.e., pump) blood out of the finger, and the device also includes an anticoagulant deposited in the flow path or collection container to stabilize the collected sample.
[0011] According to one design, the device can include separate components such as a holder, a lancet, and a collection container. According to another design, the lancet and collection container can be integrated into a device that is then used with the holder. According to yet another design, the holder, lancet, and collection container can be integrated into a single system. Any of these designs are contemplated for use as a self-contained disposable device and / or in conjunction with an external power source for pain relief control. The capillary blood collection device can be used as a platform for a variety of capillary blood collection containers (from small tubes to capillary dispensers) as well as an onboard plasma separation module. This capability extends product flexibility to a variety of applications, including distribution to point-of-care (POC) boxes or transfer of small collection tubes that can be used in centrifuges or analytical instruments.
