A fluid injector system configured for use in administering at least one fluid to a patient, the fluid injector system including at least one image capture device configured for capturing image data in an environment surrounding the fluid injector system; and a control device comprising at least one processor programmed or configured to receive, with the at least one processor, the image data captured by the at least one image capture device; determine, with the at least one processor, whether the received image data comprises at least one predetermined characteristic; and perform, with the at least one processor, at least one action in response to determining whether the received image data comprises at least one predetermined char-acteristic.

A system for confirming acquisition of a fluid sample is provided. The system includes a wearable electronic device configured to be worn by a user. The device has a housing, at least one imaging sensor associated with the housing, a data transmission interface for sending data to or receiving data from an external electronic device, a microprocessor for managing the at least one imaging sensor and the data transmission interface, and a program for acquiring and processing images acquired by the at least one imaging sensor. The system further includes a sampling device for collecting a fluid sample in a sample container and at least one identification tag attached to or integrally formed with the sampling device or sample container. The at least one identification tag includes or is associated with a tracking code.

An injection device may include a housing and a baseplate coupled to the housing. The baseplate may include a flange portion and an axial portion that extends from the flange portion in a longitudinal direction of the housing. The baseplate may be an opaque, polymer material that is more thermally conductive than a material of the housing. The injection device may additionally include a syringe at least partially disposed within the housing. The syringe may include a needle. The injection device may include a deployment mechanism configured to move the syringe relative to the housing from a retracted position to a deployed position in which the needle projects beyond the baseplate. At least a portion of the syringe may be visible when the syringe is in the retracted position.

A method for tracking injection site information includes displaying, on a user interface, a plurality of injection zones, each of the plurality of injection zones representing a segment of the body suitable for medication injection and including a graphical indicator indicating a period of time since a most recent previous injection in the injection zone. The method also includes receiving, via the user interface, injection information relating to a new injection in a particular injection zone. The method also includes updating a graphical indicator of the particular injection zone on the user interface to indicate a new date and time of injection to the particular injection zone.

A surgical device that provides a suction force against a patient's body. The device includes a handle and a suction head pivotally attached to the handle. The suction head includes an open-ended suction chamber having a rim positioned to engage the patient's skin. An actuator on the handle operates a pump to draw a negative pressure in the suction chamber, causing the rim to seal against the patient's skin via the suction force. Once the suction force is initiated, the user may lift the handle away from the patient's body to lift tissue. The lifted tissue provides a site for insertion of a trocar or Veress needle for a laparoscopic procedure in some embodiments. A gimbal disposed between the handle and the suction head provides at least two degrees of freedom such that the handle can be rotated and pivoted to optimize the direction of applied lifting force.

A skin treatment device using both a radiofrequency and medication and including tightening members, includes a skin expansion module configured to stretch a region of the skin into which first needles are inserted to be tightened, the skin expansion module including a guide body protruding outward from a lower end of a handpiece main body and a pair of tightening members hinge-coupled to hinge shafts provided on a left side and a right side of the guide body to be rotatable, wherein lower ends of the pair of tightening members are spread outward while pressurizing the skin in contact with the skin when the handpiece main body is moved downward.

A smart tourniquet includes a casing having a control unit; a contact area arranged to the casing, configured to contact a patient's skin, and connected to the control unit; a cuff arranged to the casing with an inflatable bladder; an adjustable strap arranged to the cuff for securing the cuff and casing to the patient; a pump contained in the casing, connected to the bladder, and controlled by the control unit; a thermoelectric module contained in the casing, controlled by the control unit, and connected to the contact area; and at least one sensor contained in the casing for detecting blood pulse and controlled by the control unit. The control unit is configured to inflate and deflate the bladder in response to blood pulse for changing a pressure around an arm or leg and to heat the contact area for vasodilating a vein under the patient's skin for visual detection.

Methods of actuating a needle array device can include causing fluid to move through flow channels to needle apertures that are spaced apart from an inflow aperture at different distances where flow channels that have approximately equal pathway lengths and where the fluid can reach tips of the needle apertures approximately simultaneously, which can provide an approximately equal dosage or fluid volume through the tips of the needle apertures.
