Embodiments described herein are directed to non-invasive detection of peripheral arterial disease. For example, a measuring apparatus is used to measure a patient's calf circumference. The measuring apparatus has text feature(s) or indicator(s) printed thereupon that indicate the likelihood that the patient has peripheral arterial disease based on the measured calf circumference. The assessment may be further refined by using a software application that assesses the likelihood of the patient having peripheral arterial disease using at least the calf circumference measurement, along with other information/data. Based on the assessment, a healthcare practitioner may prescribe a walking program for the patient to follow. A software application may track compliance of the walking program and provide escalating reminders to the patient if the patient continues to fail to comply with the prescribed walking program.

A measurement device is disclosed for measuring a change in one or more of a circumference or a perimeter of at least a portion of an object having a surface. The measurement device includes a first part for attachment to the object, a second part having a first portion moveable relative to a first portion of the first part, a determining device for determining a displacement of the first portion of the second part relative to the first portion of the first part caused by the object changing, and a biasing device for biasing the first part and the second part towards engagement. The measured displacement is for use in determining the change in one or more of a circumference or a perimeter of the object.

Orthopedic systems and methods are provided for use in preparing joints for implants. Specifically, hip preparation systems and methods are disclosed which can include a surgical orientation device. The hip preparation systems and methods can be used, for example, to orient the hip during the procedure, determine the orientation of an anatomical plane or planes, and orient a prosthetic component or components.

An anthropometric measurement device for measuring anatomical features includes: a sheet having a width and a length; a plurality of incisions extending from an edge of the sheet, each of the plurality of incisions spaced apart a distance so as to define a plurality of slats between the incisions. The slats are configured to be displaced in a direction normal to the plane of the sheet and held in position when the edge of the sheet is pressed over the anatomical feature, so as to indicate a dimension of the feature.

Apparatus and methods are described for setting rehabilitation goals for a patient, measuring patient movements, storing the movement data for later transfer to a computer, displaying progress indicators and inspirational messages based on progress towards goals, reporting movement, skin temperature and swelling data to a caregiver so that they monitor compliance and be aware of potential infection. The invention consolidates data from motion, temperature and swelling sensors placed on the patient with data received directly from the patient in response to questions displayed on a tablet computer screen, to create one or more representative values indicating the patient's current status. These representative values may include the patient's degree of compliance with their prescribed exercise and icing regimen; their degree of wellness based on their self-reported pain scale and sensed temperature and limb swelling; and their current level of physical activity as detected by the motion sensors.

The present disclosure is directed to a method of surgery, such as knee replacement surgery and hip replacement surgery that achieves optimal implant sizing and placement within a surgically repaired joint.

A system for monitoring foetal growth. The system may include a plurality of devices. Each device of the plurality of devices may be configured to determine measurements of a baby bump over a time period, and may be further configured to store the measurements. The system may also include a server configured to receive the measurements from each of the plurality of devices. The server may be configured to compare the measurements from different devices of the plurality of devices. The system may be further configured to send an alert upon detecting an abnormality based on the measurements from the different devices of the plurality of devices.

A phlebostatic axis locating device for locating a phlebostatic axis of a homosapien includes a straightedge and a measuring stick. The measuring stick is slidably coupled to the straightedge proximate to a terminus of the straightedge, defining an intersection. The measuring stick extends perpendicularly from the straightedge. The straightedge is configured to position on the fourth intercostal space of a substantially supine homosapien supported on a surface, such that the straightedge is substantially parallel to the surface. The straightedge extends substantially perpendicularly from a centerline of a chest of the homosapien such that the terminus of the straightedge is positioned beyond the chest. An end of the measuring stick is configured to position on the surface, with the measuring stick substantially perpendicular to the surface. A midpoint of a distance between the intersection and the surface is determined. The midpoint corresponds to a phlebostatic axis of the homosapien.

An ultrasound diagnostic apparatus (1) includes an ultrasound probe (2) having a predetermined size; and a portable diagnostic apparatus main body (3), in which the diagnostic apparatus main body (3) includes a camera (25) that captures an optical image including a wound region of a subject and the ultrasound probe, an image generation unit (22) that generates an ultrasound image for the wound region, a monitor (24) that displays the optical image and the ultrasound image, an extraction unit (26) that extracts the wound region and the ultrasound probe from the optical image, and a wound size calculation unit (27) that calculates an actual size of the wound region on the basis of the predetermined size of the ultrasound probe (2) by comparing the extracted wound region and the extracted ultrasound probe (2), and displays the actual size on the monitor (24).

A measuring tape for measuring the size of limbs or waists is provided with a tape head capable of being stably inserted into a positioning hole during measurement and being automatically ejected out of the positioning hole after measurement, and includes a shell, and a cavity formed in the shell and used for receiving a flexible rule. An elastic switch assembly for clamping the tape head in the positioning hole is disposed at a position, close to the positioning hole, in the cavity. The elastic switch assembly and a leaf spring are disposed in the positioning hole, allowing the tape head to be inserted thereinto, in the shell, such that the tape head can be stably disposed in the positioning hole after being inserted into the positioning hole, and will not slide out of the positioning hole when users observe measure data.
