Automatic slide switch with infusion hook

Abstract

The invention relates to an automatic slide switch with a transfusion hook. The automatic slide switch connected with the transfusion hook comprises a shell, a spring, a slider moving contact, two fixed contacts and a connecting rod. The shell consists of an upper insulation section, a contact section and a lower insulation section, the two fixed contacts are arranged on the inner wall of the contact section, the slider moving contact slides up and down in the shell, the lower portion of the slider moving contact is connected with the connection rod, and the spring sleeves the connection rod which is connected with the hook. When the hook is in zero load, the slider moving contact is ejected to the upper insulation section by the spring, and the switch is open; when the hook is in heavy load, the slider moving contact is pulled to the lower insulation section, and the switch is off as well; when the hook bears a response load, the slider moving contact is ejected to the contact section by the spring, the switch is closed. The automatic slide switch is capable of automatically closing and opening a transfusion alarm circuit according to transfusion conditions and has the advantages of trouble saving, freeness from worries, sensitiveness, durability, simple structure, convenience in mounting and maintenance, less proneness to false alarm and the like.

Description

[0001] Technical field [0002] The invention relates to a medical infusion auxiliary device, which is an automatic sliding switch with an infusion hook, which can be automatically disconnected when the hook is empty when the infusion is performed in a hospital, and can also be automatically disconnected when the infusion hook is overloaded (during infusion). Open and close automatically only when the infusion bottle bag on the hook is empty. Background technique [0003] During the infusion process in the hospital, it often occurs that the infusion is not completed in time, which sometimes causes unnecessary damage to the patient.
