Devices associated with on-body analyte sensor units are disclosed. These devices include any of packaging and/or loading systems, applicators and elements of the on-body sensor units themselves. Also, various approaches to connecting electrochemical analyte sensors to and/or within associated on-body analyte sensor units are disclosed. The connector approaches variously involve the use of unique sensor and ancillary element arrangements to facilitate assembly of separate electronics assemblies and sensor elements that are kept apart until the end user brings them together.

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 blood glucose detection device and system are portable blood glucose detection devices for patients. The blood glucose detection device includes a plurality of lancing units, which collect patient blood and generate current. The test unit can detect the current and transmit the current intensity data to the external device, thus making the glucose detection device portable. Besides, there is no need to change test strips every time for a blood glucose test as the current intensity data can be transmitted externally for management, which improves the patient's experience and makes it convenient for patients to perform blood glucose tests when they go out.

An integrated testing device and fluid module are disclosed, as well as a method of manufacture. Fluid module contains a reservoir containing a test fluid, and a control vessel. The reservoir discharges test fluid into the control vessel, which discharges the test fluid in a controlled way to a test component.

Devices and methods for withdrawing bodily fluid from a subject are disclosed herein. In some embodiments, a handheld device can include a housing having an opening, a skin-piercing assembly, and an actuator coupled to the skin-piercing assembly. The skin-piercing assembly can include a casing, a drive member pivotably mounted within the casing and carrying a blade, and a biasing member coupling the drive member to the casing. The actuator can be movable relative to the housing from a first position to a second position. In the first position, the drive member can engage the casing to maintain the biasing member in a biased configuration. Movement of the actuator from the first position to the second position can disengage the drive member from the casing to permit the biasing member to drive the blade at least partially through and/or across the opening in the base.

A push-type blood collection needle includes a housing having an accommodating cavity therein, a rear cover and a needle body disposed in the accommodating cavity. The rear cover is movably disposed on the housing, and the rear cover has a supporting leg extending into the accommodating cavity. The needle body is provided with a rib. The accommodating cavity is internally provided with a projecting part that cooperates with and blocks the bottom of the rib. The supporting leg is provided with a stopper that cooperates with and blocks the side wall of the rib. And an elastic member is disposed between the needle body and the rear cover.

A device which, in a shallow region including the epidermal layer or the dermal layer, can administer a target even in extremely small amounts. This includes a puncture needle which, in a flat puncture unit for puncturing the shallow region, has a groove and a through-hole which constitute a recess that extends through part of or the entire thickness of the puncture unit; and a casing which houses the puncture needle so as to allow the puncture needle to advance. By part or all of a flow agent containing the drug being arranged in the groove and the through-hole, the drug is positioned with respect to the puncture unit. The device is designed such that a flow agent in the amount of 10-1000 nL is dosed in the shallow region per puncture.

A sample collection device for collecting a blood sample of a patient, the sample collection device including a first partially deformable shell and a second at least partially pierceable shell with a pre-packaged vacuum sealed between the first shell and the second shell. The second shell may additionally hold a sample container and an automatic mechanical cutting mechanism including a rotatable cutting blade and an actuator spring, the actuator spring being actuatable by pressing the first shell, thereby releasing and rotating the cutting blade. By pressing the first shell, the pre-packaged vacuum is released to a collection opening of the second shell such that the vacuum effects a suction effect so that blood coming out of the incision created by the rotatable cutting blade leaks into the sample container.

A dermal patch for collecting a physiological sample includes a housing with a collection chamber, a sample channel and a pin within a receptacle of the housing. The sample channel is configured to direct a physiological sample drawn from a subject to the collection chamber. The pin is removably positioned within the receptacle and is configured to move from an undeployed position to a deployed position. The pin is configured to seal the receptacle when in the undeployed position and is further configured to facilitate generation of negative pressure in the sample channel when the pin is moved from the undeployed to the deployed position.
