The injector of the present invention comprises a plunger capable of launching the lancet in a pricking direction, an injector housing which surrounds the plunger, and an injector cap capable of being attached and detached with respect to the injector housing. In particular, an inner face of the injector cap is provided with a rib, and the rib and the plunger moving for the pricking are capable of contacting with each other.

A device for collecting a physiological sample from a subject includes a lancet with a needle that is configured to puncture the subject's skin and a cartridge configured to engage with the lancet. The lancet is configured to transition the needle from an undeployed position to a deployed position in response to engagement with the cartridge, thereby allowing the needle to puncture the subject's skin.

An integrated bodily-fluid-component analyzing apparatus includes a main body, a lancet holder connected to the main body so as to be movable back and forth along a predetermined movement path, a lancet removably attached to the lancet holder, and a test strip that is removably attached to the main body and is used to measure a component of the bodily fluid flowing from a pricked site of the living body pricked with the lancet. The movement path of the lancet holder and a bodily fluid inlet of the test strip face a specific position that is in a vicinity of the main body and at which the pricked site is to be placed. The apparatus further includes a pressing section that presses a portion of the living body adjacent to the pricked site so as to cause the bodily fluid to flow from the pricked site.

The invention relates to an ingestible, implantable or wearable medical device comprising a microarray which comprises a bioactive agent capable of interacting with a disease marker biological analyte; a reservoir which comprises at least one therapeutic agent and is capable of releasing the therapeutic agent(s) from the medical device; and a plurality of microchips comprising a microarray scanning device capable of obtaining physical parameter data of an interaction between the disease marker biological analyte with the bioactive agent; a biometric recognition device capable of comparing the physical parameter data with an analyte interaction profile; optionally a therapeutic agent releasing device capable of controlling release of the therapeutic agent from the reservoirs; an interface device capable of facilitating communications between the microarray scanning device, biometric recognition device and the therapeutic agent releasing device; and an energy source to power the medical device. Specifically, the invention relates to a medical device capable of detecting an analyte in a bodily fluid comprising at least one microneedle capable of obtaining a sample of a bodily fluid, a first microchannel through which the sample flows and is in fluid communication with the at least one microneedle, a second microchannel in fluid communication with the first microchannel, through which a buffer flows, wherein the second channel comprises a microarray with a bioactive agent, a microarray scanning device to detect an interaction between the bioactive agent and the analyte in the bodily fluid; and an interface device.

A lancet device includes a housing, a removable front cap mounted to the housing, a lancet holding member, a trigger and an arming system comprising a grippable cocking member structured and arranged to place the lancet device in a trigger-set or armed position. A depth adjustment system includes a member that is at least slidable and partially rotatably mounted and that has an axis of rotation arranged substantially parallel to a center axis of the lancet holding member. An ejection system includes an ejector having a portion extending outside a sidewall opening of the housing and being located closer to a front end of the housing than to a rear end of the housing. The sidewall opening of the housing is arranged on an area of the housing located between the trigger and a wall of the housing located opposite the trigger. The ejection system is structured and arranged to at least one of prevent axial movement of the lancet holding member or remove or eject a lancet from the lancet holding member.

An automated method of evaluating a collected fluid sample includes: filling a sample cavity with the collected fluid sample; adding a buffer solution; separating the collected fluid sample into a first portion and a second portion; mixing the second portion with tagged antibodies; removing leftover tagged antibodies; and measuring a difference between the first portion and the second portion. A sample collection and testing device includes: a reference cavity comprising a reference fluid sample; a test cavity comprising a test fluid sample; a reference measurement element associated with the reference cavity; and a test measurement element associated with the test cavity. A method of evaluating a collected fluid sample including: separating the sample; pumping a first portion to a first measurement cavity; adding a solution to a second portion and pumping the mixture to a second measurement cavity; and measuring a charge difference between the first and second measurement cavities.

A lancing device includes a housing, a lancet carrier translational within the housing, a drive spring for propelling the lancet carrier through a translational lancing stroke, and a charging mechanism. The charging mechanism includes a first cam member that is rotatable relative to the housing, a second cam member that abuts the first cam member, is coupled to the lancet carrier, and is restricted from rotation relative to the housing, and a rotatable handle co-rotationally attached to the first cam member. Rotation of the handle rotates the first cam member with it, causing the first cam member to rotate against the second cam member, which in response traverses axially because it is restricted from rotation, thereby retracting the lancet carrier to a retracted or charged state.

A lancing device has a charging mechanism that operates to convert an external push action by a user to an internal pull action that retracts and charges a lancet for use in a lancing stroke. In some embodiments, the charging mechanism includes a user-actuated charging push-button, a reverse charging member coupled to a lancet carrier, and a reverse-motion conversion member coupled therebetween. Depressing the user-actuated member in a first longitudinal direction causes transverse movement of the conversion member, which in turn causes longitudinal retraction of the reverse charging member and the lancet carrier coupled thereto in a second longitudinal direction opposite the first direction, thereby charging a drive mechanism of the lancing device. In other embodiments, a rack-and-pinion gear mechanism provides the same push-to-pull functionality.

This liquid sample measurement device is provided with: a lancet mounting part to and from which a lancet device having a skin contact section for puncturing skin can be attached and detached; a sensor mounting part to which a biosensor, which is spotted with blood that comes out from the punctured skin, can be attached; and a measurement part that uses the biosensor attached to the sensor mounting part to measure the amounts of substances in the blood. The liquid sample measurement device includes a feature that makes it necessary to replace a lancet device that has been attached to the lance mounting part and has punctured skin, each time a lancet device is used to puncture skin.
