The present disclosure relates to a capillary blood collecting device which includes a fixing device including an accommodating cavity for accommodating a blood collection finger and a squeezing member for squeezing blood to a fingertip site. The capillary blood collecting device is configured to detachably accommodate at least one skin puncture part on a blood collection side of the finger, and the skin puncture part includes a blood lancet that may be driven to puncture the blood collection finger, such that a sufficient amount of capillary blood quickly flows out from the capillary blood converged at the fingertip under the action of blood lancet.

An apparatus comprises a diffuser, a connection tube section forming a tubular fluid passage, a first indicating element section that indicates a measurement related to a body fluid disposed between a distal end and the connection tube section, a second indicating element section that indicates that the first indicating element section is suitable for use, and a housing having a generally tubular body. The diffuser is at least partially disposed in the generally tubular body. A fluid chamber adapted to receive fluid is cooperatively defined by the housing and the diffuser. The first indicating element section is visibly disposed in a first section of the housing. The second indicating element section is disposed within the fluid chamber. A micro-needle collector to draw the fluid from a source to the distal end is attachable to the distal end.

Improvements in and relating to blood sampling devices A blood sampling device includes a housing and a lancet supporting a lancet needle or tip, the lancet and needle being urged or urgeable in a pricking direction. A trigger mechanism is moveable to a fire position for releasing the lancet to travel in the pricking direction. A removable safety cap initially covers the lancet needle. The lancet has an initial position in which movement of the trigger mechanism to its fire position is blocked and an intermediate position in which the trigger mechanism may be moved to its fire position. The intermediate position is obtainable only on removal of the safety cap.

The biological test kit is a device for drawing and, optionally, testing biological samples. The biological test kit is an array of lancets set in wells in a rigid base. Each lancet well is covered by a protective cover which when deformed permits the lancet to puncture a user or other patient. In one embodiment the biological test kit employs distinct covers for each lancet and in another the covers are formed from sheet material formed into blisters which cover the lancet.

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.

In one aspect, a dermal patch is disclosed, which comprises at least one needle configured for puncturing a subject's skin so as to allow drawing blood from the subject, a first blood-transfer fluidic channel for receiving at least a portion of the drawn blood, and a serum-separation element fluidly coupled to said first blood-transfer fluidic channel for receiving at least a portion of the drawn blood and separating a serum component thereof. In some embodiments, the dermal patch may include at least one reservoir for storing blood-processing reagent(s).

Embodiments of the present invention provide magnetic lancet devices and methods for driving a lancet. For example, a magnetic lancet device may include a driving mechanism having a plurality of magnets and a lancet coupled to the driving mechanism. A magnetic interaction between the plurality of magnets is configured to drive the lancet from an engaged position to a penetrating position.

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.

Provided herein are devices, systems, kits and methods for obtaining genetic information from cell-free fetal nucleic acids in ultra-low amounts of biological samples. Due to the convenience of obtaining ultra-low amounts of samples, devices, systems, kits and methods can be at least partially employed at a point of need.

This invention is in the field of medical devices. Specifically, the present invention provides portable medical devices that allow real-time detection of analytes from a biological fluid. The methods and devices are particularly useful for providing point-of-care testing for a variety of medical applications.
