Description

  The present invention relates to a hook, and more particularly, to a hook suitable for holding a display surface of a bag container containing a drip medicine in a state directed in a specific direction.

  For example, in the medical field, various instillations stored in bag containers are stored, and these instillations are generally adopted in the form of work in which nursing staff prepares in advance for medication according to a doctor's instructions. ing. Such work is normally performed using a work table such as a table installed in the nurse station. In this case, it is possible to hold the bag container by arranging a horizontal member above the work table and hooking the horizontal member with a hook.

  Patent Document 1 discloses a hook including an upper hook forming member and a lower hook forming member connected to a lower end portion of the upper hook forming member.

JP 2003-245189 A

  However, although the hook described in Patent Document 1 allows relative rotation in the horizontal plane between the upper hook forming member and the lower hook forming member, the hook is used for relatively rotating the upper hook forming member and the lower hook forming member. A separate member is required, and the relative rotation is not allowed only by the two members of the upper and lower hook forming members. Therefore, there is an inconvenience that the number of parts increases and the assembly becomes complicated.

  Further, Patent Document 1 does not employ a mechanism that holds a position where the position of the lower hook forming member is directed in a specific direction as a stationary position. For example, when a human body comes into contact with a bag container holding a drip medicine, or when a tube connected to the drip medicine is pulled, a lower hook is formed. The member is inadvertently rotated with respect to the upper hook forming member, resulting in an inconvenience that the display surface is directed in an unintended direction.

  As is well known, the infusion drug bag container is provided with a display of patient information, etc., so that the display surface always faces in a certain direction in order to prevent medication errors. Although it is necessary to keep it in an easy-to-see state, it is the actual situation that a known hook has not been devised in terms of structure corresponding to such a need.
