摘要:
The present invention generally relates to systems and methods for delivering and/or receiving a substance or substances such as blood, from subjects, e.g., from the skin and/or from other tissues of the body. In some cases, the device may contain a substance transfer component such as needles or microneedles, which can be inserted into the skin or another organ to deliver and/or receiving fluid or other substances from the subject. In some embodiments, the device may include an activator constructed and arranged to insert one or more substance transfer components into the skin or other organ. In certain cases, the device may also include a storage chamber for receiving a fluid received from the subject.

The present invention is generally directed to systems and methods for sampling fluids from subjects. The fluid may be any suitable bodily fluid, e.g., blood or interstitial fluid. In some cases, the subject is a patient. The subject may have a device that can be applied to the skin of the subject (e.g., by the subject, or another person), and the device is able to obtain a sample of fluid. The fluid may be stored within a reservoir in the device, and the fluid may be obtained from the subject at any convenient time, e.g., at home, away from a healthcare setting, etc. In some embodiments, the device, or a portion thereof, may be returned to a clinical and/or laboratory setting to analyze the fluid stored within the device.
摘要:
The present invention generally relates, in certain aspects, to systems and methods for application to the skin, and control of actuation, delivery, and/or perception thereof. For example, certain aspects of the invention are generally directed to devices for delivering to and/or withdrawing fluid or from subjects, e.g., to or from the skin and/or beneath the skin. In one aspect, the delivery and/or withdrawal of fluid is at least partially obscured. For example, the obscuration may be by time, and/or by sensory obscuration (e.g., by providing tactile, olfactory, auditory, and/or visual sensations). Certain aspects of the invention are generally directed to devices able to automatically deliver to and/or withdraw fluid from the skin and/or beneath the skin after activation, e.g., where the fluid is delivered and/or withdrawn without the need for any additional intervention. The devices may be activated by any suitable technique. In other aspects, a device may be contained in a package, and when removed from the package, the device may be constructed and arranged to be able to deliver and/or withdraw fluid when the device is applied to the skin, and in some cases, automatically and/or without any further intervention by the subject or another person.
摘要:
The present invention generally relates to receiving bodily fluid through a device opening. In one aspect, the device includes a flow activator arranged to cause fluid to be released from a subject. A deployment actuator may actuate the flow activator in a deployment direction, which may in turn cause fluid release from a subject. The flow activator may also be moved in a retraction direction by a retraction actuator. In one aspect, the device may include a vacuum source that may help facilitate fluid flow into the opening of the device and/or may help facilitate fluid flow from the opening to a storage chamber. In one aspect, a device actuator may enable fluid communication between the opening and the vacuum source and the flow activator may be actuated after the enablement of fluid communication.
摘要:
The present invention generally relates to devices and techniques associated with diagnostics, therapies, and other applications, including skin-associated applications, for example, devices for delivering and/or withdrawing fluid from subjects, e.g., through the skin. In some embodiments, the device includes a system for accessing an extractable medium from and/or through the skin of the subject at an access site, and a pressure regulator supported by a support structure, able to create a pressure differential across the skin at least a portion of the access site. The device may also include, in some cases, a sensor supported by the support structure for determining at least one condition of the extractable medium from the subject, and optionally a signal generator supported by the support structure for generating a signal relating to the condition of the medium determined by the sensor.
摘要:
An apparatus and methods for delivering ocular implants or microimplants. The apparatus is ergonomically designed for ease of use, and a simple manual depression of an actuator produces proportional movement of a linkage causing the implant or microimplant to be ejected through a cannula disposed at the desired location in the eye. Small gauge cannulas are provided for self-sealing methods of delivery.
摘要:
A channeled under floor heating element incorporating channeled areas for accepting heat and sensor wires. The inventive channeled under floor heating element includes an arrangement of seam structures defining channels housing substantially discrete elongate heating and sensing elements arranged in a substantially similar pattern.
摘要:
A warming mattress and mattress pad incorporating an insert layer or sheet with a scrim having one or more pairs of heating and/or sensor wires arranged in a continuous pattern such that pair members are disposed in crossing relation to one another. The pair members may be cut and joined to establish electrical connections at defined crossing points to establish feedback loop circuits with a control element.
摘要:
A warming blanket incorporating channeled areas for accepting heat and/or sensor wires. The inventive blanket includes multiple layers of knitted, woven or non-woven fabrics that are welded together with ultrasonic seams to define channels through which wires for resistive heating can be placed. This composite may be produced in a continuous process, providing the composite in roll form.
