A blood vessel visualization apparatus for visualizing a blood vessel inside a living body with light that has been transmitted through the living body includes: an irradiation unit configured to emit light from a contact portion with skin of the living body, the irradiation unit including: a fixing portion configured to be fixed to a target site of the living body, wherein the fixing portion includes a surface configured to contact the skin of the living body, and a plurality of light sources located in a light source arrangement area at the surface of the fixing portion that is configured to contact the skin of the living body. A brightness and/or a light distribution angle of respective ones of the light sources differ according to positions of the light sources in the light source arrangement area.

A blood vessel visualization apparatus, a blood vessel puncture system, and an observation window member include an observation window that contains a wavelength conversion material for converting near infrared light into visible light, and that is configured to visualize an image of the near infrared light that has been radiated from a light source that irradiates with near infrared light a visualization target site at which a blood vessel of a living body is visualized, and that has then passed through the visualization target site.

A body fluid sensing device with a body fluid capture structure and a body fluid measurement sensor positioned in the body fluid capture structure. A capacitance sensor is coupled to the body fluid measurement sensor. The capacitance sensor is used to assist in the positioning of a body part relative to the body fluid capture structure.

Systems and methods encourage users to rotate injection sites and avoid lipodystrophy. Sleeves and/or lost-tooth gear dials and/or microswitches in or on injection pens or their caps, on vials, and on other portable devices manually adjust an indicator before or after an injection to show a current or next injection site in accordance with a site rotation plan. Injected medicine packaging and related printed indicia encourage site rotation. Optical devices employing optical mouse or projection technology help locate and/or distribute injection sites within a body area. A mobile phone app tracks injections and locations to select next injection site, and can use imaging to locate a target injection site and optionally diagnose lipodystrophic conditions and record them. Tactile and print media educational tools are presented to help users palpate and identify lipos in body areas having injection sites.

A system to measure and display the orientation of a handheld instrument is disclosed.

The present invention relates to the intravenous injection aid for indicating vein, comprising: a compression strap; a binding means disposed at the opposite ends of the compression strap; a near-infrared lamp disposed at the compression strap; and a controller disposed on the compression strap for controlling the near-infrared lamp. The present invention as mentioned above may not only indicates vein with high visibility but also keep the vein from swaying or moving even during intravenous injection, so the intravenous injection can be carried out safely and efficiently.

An adhesive bandage system features a first member with an aperture substantially circumscribed by an adhesive layer couplable to a patient's skin. A second member of the adhesive bandage is removably couplable to the first member, having an adhesive along an outer perimeter on a first side, the outer perimeter sized so as to overlap with the first member. In some methods of use, a user may adhere the first member to a patient skin, administer a topical medication through the aperture, and then adhere the second member so as to cover the aperture. The second member may be removed, as needed, to either add medication, replace the medication with a new medication, or to have access to an injection site with a needle or catheter.

The present disclosure provides a template for marking injection sites on a biological surface prior to performance of a medical procedure, wherein the template comprises a flexible sheet having marked positions or demarcated areas for each injection site, and wherein each marked position or demarcated area is associated with a unique identifier. Also provided are methods of using such disclosed templates in a medical procedure where an agent or material is injected into a patient.

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.
