Description

  When injecting a contrast medium from the arm, instilling into the blood vessel of the arm, or when supplying nutrients through the nose or mouth, the patient consciously uses a tube or catheter for that purpose, Alternatively, the present invention relates to an arm movement restricting tool that restricts the movement of the arm so as not to unconsciously remove it.

There are several proposals for this type of arm movement restrictor.
The first is to attach a band that wraps and fixes the fixed cover around the arm on the outer surface of the resin-made arc-shaped fixed cover that is wrapped around and covers the outer half of the arm, and the inner surface width direction of the portion that hits the arm of each band In addition, an arm fixing device (Patent Document 1) is formed by attaching a plurality of plastic round bars or the like that relax the pressure on the blood vessels of the arms at appropriate intervals.

  When instilling, place an arm on the fixed cover, and in that state, wrap a band around the upper arm and wrist, thereby restricting the movement of the arm, At this time, it is used to prevent the drip needle from coming off or the chemical solution supply tube from coming off. In this arm fixing device, since a plurality of plastic round bars or the like are attached to the inner surface side of each band, the pressure on the arm's blood vessels is relieved and the blood flow is suppressed in the above use state. It is said that there is no fear.

  The second is that it is inserted into a replaceable bag, and the concave side of the wrapped groove-shaped hard core material is configured to contact the outer surface of the arm through the bag, and further to bands attached to both sides of the bag. This is an arm fixture (Patent Document 2) in which a buffer material is provided and the band is wound around the arm so that a hard core material can be fixed to the arm.

  Also when instilling, the arm is placed on the hard core material through the bag, and in this state, the upper arm part and the wrist part are wrapped and fixed with the banding material through the cushioning material, thereby controlling the movement of the arm. It is used to regulate and prevent the arm from moving and the infusion needle from coming off or the chemical solution supply tube from coming off during infusion.

The third is a core member that is rigid in the longitudinal direction and has a curvature that can be wound around the arm in the lateral width direction, an unfolded rectangular outer body housing the core member, and an arm-wrapped state of the outer body And holding means to keep
The core member is a corrugated plate housed in the exterior body so that the peak portion faces in the longitudinal direction, a solid or hollow bar housed in the exterior body so as to face the longitudinal direction, or the longitudinal direction so as to face the longitudinal direction. Consists of strip material stored in the exterior body,
The holding means is constituted by a planar fastener means,
It is a safety protector (patent document 3) which provided the cushion member between the edge part of the longitudinal direction of the said core member, and the inside of the said exterior body.

  This is because when performing infusion or other treatments, the arm on the side different from the side to be directly treated, such as the side where the infusion needle is stabbed, is placed on an exterior body with a core member and wrapped around the arm. The state is held by a holding means such as a surface fastener means, thereby restricting the movement of the arm and the tracheal tube inserted into the injection needle, mouth or nose of the other arm is removed. It is used to prevent this.

  At this time, the safety protector is said to be a thing that does not deteriorate blood circulation in the arm and does not have to feel that the person to be treated is bound.

  These are all used as described above, and it is considered that the corresponding effects can be obtained, but the holding state in the length direction of the mounting state to the arm is not sufficient, and it is attached to the arm. If the person moves his / her arm, there is a risk of shifting in the length direction. Further, if the size is made small so as not to be displaced, there is a possibility that problems such as tightness and poor blood circulation may occur. In addition, since it is assumed that the arm is completely straightened, it may be uncomfortable for a person wearing it to maintain it. Furthermore, since many parts of the arm are covered, there is a risk that the temperature will rise and become steamed in summer.
