Pediatric blood drawing nursing device

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a pediatric blood drawing nursing device which comprises a square block, threaded holes used for connecting and fixing are formed in the four ends of the square block, a second transmission rotary disc used for transmission is arranged at the side end of the square block, and through arrangement of an annular sleeve, one end of the annular sleeve is fixedly connected with a circular groove of a square baffle, and the other end of the annular sleeve is limited by a limiting block in the circular groove through an arc-shaped convex block. According to the device, the arc-shaped protruding block is used for clamping and limiting the limiting block, the effect of facilitating the expansion and contraction of the diameter of the annular sleeve is achieved, so that the fixing effect is achieved, meanwhile, the annular sleeve can also achieve the effects of locking blood on the arm, rapidly showing meridians and facilitating medical staff to apply a needle, meanwhile, the other end of the limiting block is finally connected with a shifting rod through a connecting rod, the position of the limiting block is adjusted by shifting the shifting rod, the effect of rapidly loosening the annular sleeve is achieved, work can be rapidly carried out conveniently, and the working difficulty of medical staff is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a pediatric blood drawing nursing device.
