An intravenous splint cover may include a main body, a pair of opposing securing members, and a splinting member. The main body may be rectangular shaped and have a bottom portion and a top portion. The pair of opposing securing members may be rectangular shaped and be connected to and extend outwardly from the main body and have a bottom portion and a top portion. The splinting member may be rectangular shaped and be carried by the bottom portion of the main body and extend outwardly from the main body to create an elevated portion of the main body. The bottom portions of the pair of opposing securing members may have an adhesive material applied thereto. The bottom portion of the main body that does not carry the splinting member may have an adhesive material applied thereto.

Compression sleeve fabricated of a composite material that surrounds the joint to be supported and has a main layer of elastically stretchable material and at least one thin film of stretchable material which is laminated to the main layer and provides additional compressive forces that combine with compressive forces provided by the main layer in supporting a joint about which the sleeve is stretched. The material has a third layer which in some embodiments is a nylon jersey material, while in others it is another stretchable material that provides additional compressive forces and support.

A sleeve is provided with an antibacterial substance to substantially prevent germs from surviving thereon. The sleeve is designed to be worn by children over their existing clothes, worn over the elbow so that the wearer may cough or sneeze into it with the antibacterial substance acting to eliminate any germs transferred from the wearer to the sleeve by that cough or sneeze. The sleeve is elastic and held in place by a frictional fit that allows for easy application and removal without limiting range of motion for the user.

A substrate that can be applied to a user's body part having a region of temporally-controlled elasticity that transitions between a first state and a second state when activated, wherein the first state is more relaxed than the second state, and the substrate can at least partially revert from the second state to the first state over an extended time period resulting from the temporally-controlled elasticity of the substrate, and wherein the substrate can apply a treatment/mechanical force to the body part, as the substrate transitions from the second state to the first state.

Implementations of an arm sleeve that provides external assistance to an arm and shoulder of a user during an arm motion are provided. In one implementation, the arm sleeve comprises a framework that includes a torso portion configured to be attached to the torso of the user and an arm portion configured to receive at least a portion of the arm of the user. The framework of the arm sleeve is a unitary construction of interconnected elastic members. The interconnected elastic members include a first elastic member configured to play an active part throughout an overhead throwing motion, a second elastic member configured to decrease the concentric contraction force necessary for shoulder abduction during the cocking phase of a throwing motion, and a third elastic member configured to assist eccentrically contracting muscles during the deceleration phase of a throwing motion. In another implementation, the framework of the arm sleeve is encased by an elastomeric cover.
