The present invention generally relates, in certain aspects, to relatively small devices applied to the skin, modular systems, and methods of use thereof. In some aspects, the device is constructed and arranged to have more than one module. For instance, the device may have a module for delivering to and/or withdrawing fluid from the skin and/or beneath the skin of a subject and a module for transmitting a signal indicative of the fluid delivered to and/or withdrawn from the skin and/or beneath the skin of the subject, a module for analyzing a fluid withdrawn from the skin and/or beneath the skin of the subject, or the like. In some embodiments, the modules are connectable and/or detachable from each other, and in some cases, the connections and/or detachments may be performed while the device is in contact with the subject, e.g., while affixed to the subject. In some embodiments, the device may be repeatedly applicable to the skin of the subject to deliver to and/or withdraw fluid from the skin and/or beneath the skin of a subject, e.g., at the same location, or at different locations on the skin of the subject. In some aspects, the devices may be self-contained and/or have a relatively small size, and in some cases, the device may be sized such that it is wearable and/or able to be carried by a subject. For example, the device may have a mass and/or dimensions that allow the device to be carried or worn by a subject for various periods of time, e.g., at least about an hour, at least about a day, at least about a week, etc., or no more than about an hour, no more than about 10 min, etc.

A miniature safety blood lancet for minimizing pain includes a needle body, an activation sleeve, a housing and a spring. The activation sleeve is arranged in the housing. The needle body is arranged in the activation sleeve. The housing, the activation sleeve and the needle body are slidably connected. The activation sleeve is provided with an inner wall. The inner side of the middle of the inner wall is provided with an unlocking arm, and the outer side of the bottom of the inner wall is provided with a buckle. A needle cap is arranged at the front end of the needle body. The unlocking arm of the activation sleeve is snap-fitted with a self-locking protrusion of the needle cap and an inverted buckle of the housing, respectively. The spring is arranged between the bottom of the needle body and the housing.

A system and method for monitoring body chemistry of a user, the system comprising: a housing supporting: a microsensor comprising a first and second working electrode, a reference electrode, and a counter electrode, and configured to access interstitial fluid of the user, and an electronics subsystem comprising a signal conditioning module that receives a signal stream, from the microsensor, wherein the electronics subsystem is configured to detect an impedance signal derived from two of the first working electrode, the second working electrode, the reference electrode, and the counter electrode; and a processing subsystem comprising: a first module configured to generate an analysis indicative of an analyte parameter of the user and derived from the signal stream and the impedance signal, and a second module configured to transmit information derived from the analysis to the user, thereby facilitating monitoring of body chemistry of the user.

An automated insertion assembly includes a first dermal perforation assembly configured to releasably engage a first subdermal device. A first actuation assembly is configured to drive the first dermal perforation assembly into a user's skin to a first depth and drive the first subdermal device into the user's skin to a second depth. The second depth is greater than the first depth.

Wearable sensor patches, applicator systems for applying wearable sensor patches, and associated systems, devices, and methods are disclosed herein. In one embodiment, an applicator system includes a first applicator portion, a second applicator portion, a spring, and a trigger mechanism. The first applicator portion releasably retains a wearable sensor patch configured to detect a parameter of an analyte in fluid of a user. When the applicator system is in a loaded mode, the spring and the first applicator portion are positioned within the second applicator portion such that the spring is positioned between the first applicator portion and the second applicator portion. The trigger mechanism is configured to initiate a transition of the applicator system from the loaded mode to a released mode such that the spring accelerates the first applicator portion distally away from the second applicator portion to apply the wearable sensor patch to the user.

A repeater system may control a pump by using a repeater and a user interface. An adhesive patch system may be used for affixing a pump or other object to a human body. Such an adhesive patch system may include two sets of adhesive members, each member including an adhesive material on at least one side so as to attach to the body. The members of the first set are spaced to allow the members of the second set to attach to the body in spaces provided between the members of the first set, and the members of the second set are spaced to allow members of the first set to detach from the body without detaching the members of the second set. Also, fill stations and base stations are provided for personal pump systems.

Bodily fluid sample collection systems, devices, and method are provided. The sample is collected at a first location and subjected to a first sample processing step. The sample may be shipped to a second location and subjected to a second sample processing step that does not introduce contaminants into a plasma portion of the sample formed from the first processing step. The sample may also be mixed with other material(s) in the collection device.

A lancing device with rear adjustment of penetration depth includes a cap, cap holder, ejection pin and shell, wherein: the lancing device has an external and medium depth adjusting sleeve. The ejection pin is located in the medium sleeve and the external depth adjusting sleeve is sleeved outside the medium sleeve; the external sleeve connects axially and circumferentially to the shell, and a rotary locating mechanism is between the external sleeve and the shell; the medium sleeve is connected circumferentially and axially in a sliding way, and a rotary moving mechanism is between the medium the external sleeve, and the medium includes a passive impact face relative to the active impact face of the ejection pin; the external sleeve includes a manual adjusting ring outside the lancing device at the middle and rear part, and rotates to drive the medium sleeve to move axially, changing the needle tip penetration depth.
