Embodiment Construction

[0021] The neck retractor provided by the present invention, its special mold and preparation method will be further described in detail below in conjunction with the accompanying drawings:

[0022] like figure 1 Shown is the structural representation of the neck retractor provided by the present invention, namely comprises three latex airbags 1 stacked on top of each other, the airbags are communicated by the latex tube 2, the inflatable mechanism made of the inflatable ball 3, the air guide tube 4 and the latex airbag as the latex The latex tube head 5 of the air bag air inlet is connected. In order to realize the control of the inflation and deflation of the airbag, a control mechanism consisting of balls 6 and ball chambers 7 is provided on the air guide tube; The inflatable ball 3 leaks, and the ball 6 is squeezed into the air guide tube 4 to get final product.

[0023] like figure 2 Shown is the mold structure schematic diagram of preparing above-mentioned neck retra...

Abstract

A neck attractor for treating cervical spondylopathy is composed of several air bags and inflating unit and is prepared through providing a dedicated mould, preparing liquid latex, coating it on the surface of said mould, solidifying, demoulding, sealing, and joining it with inflating unit and accessories. Said dedicated mould is composed of a fixing mechanism, several perforated crescent-shaped moulding plates, and a mould rod for connecting all moulding plates.

Description

technical field [0001] The invention belongs to the technical field of medical orthopedic devices, and in particular relates to a neck tractor for treating cervical spondylosis, which is composed of a plurality of inflatable bags and an inflatable mechanism, and a special mold and method for preparing the device. Background technique [0002] At present, the structure of the traction and fixation treatment device used for treating cervical spondylosis is formed by superimposing an inflatable mechanism and a plurality of interconnected inflatable bags. [0003] The utility model patent No. ZL99254350 and Publication No. 2396791 discloses a structure named "Portable Inflatable Cervical Traction and Fixation Therapy Device". , the airway must be connected with each airbag respectively, so its inflation mechanism has the defects of complex structure and inconvenient use by patients. [0004] In addition, there is also an inflatable cervical tractor on th...
