Provided is a self-fitting and automatically adjustable clasp band/strap which is usable in medical immobilization (e.g., casts, splints, braces) and multiple other fixation devices. The clasp band/strap may have a shape memory material and clasp members attached to two ends of the clasp band/strap. Upon stimulation by a trigger source, the shape memory material deforms which brings the two end portions closer to each other, causing the two clasp members to attach to each other to form a closure. Additionally, the clasp band/strap may include a motor, a control unit, and sensors to enable a motor actuated fine tensioning. Finally, the clasp band/strap may have an adhesive backing or any other kind of annealing or connective backing, such as a Velcro strap with an adhesive backing, for attaching to a splint or other object.

A customizable fitted device for immobilizing injuries and a method for constructing the fitted device is provided. The fitted device can be used to stabilize an arm, wrist, hand, leg, knee, ankle, foot or other body parts through custom formation. The device can be formed by a sidewall having one or more sidewall sections that can be secured together using retaining clips positioned within retaining clip slots on the device. The device can further include one or more openings defined in the sidewall of each device section while maintaining rigidity in the sidewall. The device can be constructed by of creating a 3D image scan of the particular body part on which the device will be applied, creating a design of the device to precisely match the contours of the 3D image scan, and using a 3D printer to construct the device according to the design.

An orthosis, and components thereof, that may be used as a shoulder brace for immobilization of the arm and shoulder joint may comprise components that may allow for abduction, internal/external rotation and allow for flexion and extension simultaneously. Methods of using the brace and methods of using the brace and treating shoulder injuries are similarly provided.

The arm brace supports the arm weight. The arm brace has a soft elastic arm pad that partially surrounds and protects the forearm. The arm pad is secured to a platform that is supported by a brace structure that is secured to the waist and the thigh of the patient. The weight of the arm can be supported by the hips. The brace is releasably coupled to a side of a patient's torso and thigh with belts. The brace provides rotational stability that immobilizes the arm regardless of the position of the patient. The brace has a hinge adjacent to the hip that allows the brace to immobilize the forearm while the patent dynamically moves during activities including: standing, walking, sitting, and lying down. The hand extends out from the brace so the user can perform activities such as eating, typing, and grasping.

In one aspect, a kit includes a sleeve including an outer lining and an inner lining; a pouch arranged within the sleeve and including one or more polymer sheets, a plurality of channels, and a plurality of vents; and a foam precursor capable of forming a foam within the pouch. In one aspect, a method of stabilizing a body part includes providing a sleeve including an outer lining and an inner lining around a body part; providing a pouch arranged within the sleeve and including one or more polymer sheets, a plurality of channels, and a plurality of vents; providing a foam precursor in the pouch; and forming a foam within the pouch.

A method (1100) of fabricating a personalised orthopaedic cast (900) is disclosed. The method (1100) includes 3D scanning of a body part of a user, generating a Computer Aided Design (CAD) of an orthopaedic cast (900) for the scanned body part, and simulating real-life conditions to determine mechanical stability of the modelled cast. The mechanical stability is determined through Finite Element Analysis (FEA). The method (1100) includes determining whether the mechanical stability of the modelled cast is acceptable. The method (1100) includes finalising the CAD model when the mechanical stability of the modelled cast is found to be acceptable. The method (1100) includes 3D printing the finalised CAD model to fabricate the personalised orthopaedic cast (900).

An inflatable splint can include a sleeve shaped to conform to a specific human body part and a plurality of inflatable chambers disposed on the sleeve. The sleeve, in cooperation with the plurality of chambers in an inflated condition, can be contoured to maintain the specific human body part in a desired position. A method of using an inflatable splint includes admitting a body part into a sleeve of the inflatable splint and positioning the sleeve around the body part. One or more of the plurality of air chambers are selectively inflated such that the flexible sleeve in cooperation with the plurality of chambers in inflated condition is contoured and positioned to maintain the specific human body part in a desired position.

A blood filtration system can reduce the amount of plasma constituents (e.g., water and/or electrolytes) in the blood of the patient, and accordingly increase the hematocrit value of the patient. The blood filtration system (e.g., a controller, or the like) can determine a hematocrit value of a patient. The blood filtration system can determine a venous pressure of vasculature of a patient. The blood filtration system can compensate for pressure head in a component of a blood circuit (e.g., a withdrawal line of a catheter), for example to improve the accuracy of the venous pressure determination. The blood filtration system can determine one or more resistance characteristics of a blood circuit for the blood filtration system. The resistance characteristics can correspond to a resistance to a flow of blood through a component of the blood circuit.

An orthotic device is coupleable to a fastener installation tool and is configured to be worn on an appendage of a user of the fastener installation tool. The orthotic device is configurable between a relaxed state and a rigid state, and includes at least one activation component responsive to an activation signal output by a controller in communication with the fastener installation tool. The at least one activation component changes the orthotic device from the relaxed state to the rigid state in response to operation of the fastener installation tool.
