Anti-sway pillow with chin strap suspension device

Abstract

The invention relates to the technical field of medical apparatus, in particular to an anti-shaking traction belt hanging device. The anti-shaking traction belt hanging device comprises grooves, hanging racks, a frame beam, outer rods, inner rods, a rivet, a positioning plate, a fastening knob, hooks, a traction belt, standing columns and a base. The frame beam is a horizontal rectangular frame. Each hanging rack is of an isosceles triangle framework. One hanging rack is sleeved at the same position of each of the left frame and the right frame of the frame beam. The vertex angle of each hanging rack points downwards, and the vertex angle is simultaneously hinged to the upper end of one outer rod and the upper end of one inner rod. By the anti-shaking traction belt hanging device, deviation of the traction belt can be avoided, good stability is achieved, and a height fine tuning function is provided.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an anti-shaking occipital and maxillary belt suspension device. Background technique [0002] The application number is 200820187247.9 "cervical vertebra traction frame" comprises parts such as cross bar, groove, occiput and jaw strap and hanging ring, puts into the groove of cross bar to realize the positioning of occiput and jaw strap through the hanging ring of occiput and jaw strap. Such technical features have the problem of poor stability. Since the occiput-chin strap is positioned by the hanging ring on its top, and the hanging ring is in the groove of the cross bar, although the upper beam of the hanging ring cannot move along the longitudinal direction of the cross bar, it can move along the transverse direction of the cross bar. The lateral movement of the hanging ring will cause the lateral deviation of the occipital and maxillary belt, which will cause di...

Problems solved by technology

Such technical features have the problem of poor stability

Since the occiput-chin strap is positioned by the hanging ring on its top, and the hanging ring is in the groove of the cross bar, although the upper beam of the hanging ring cannot move along the longitudinal direction of the cross bar, it can move along the transverse direction of the cross bar. The lateral movement of the hanging ring will cause the lateral deviation of the occipital and maxillary belt, which will cause discomfort to the patient and affect the effect of the treatment.

In the process of treatment, it is a very important technical link to adjust the height of the occipital and maxillary belt to an appropriate value. The height of the occipital and maxillary belt can only be adjusted by adjusting the height of the column. Since the device itself has a certain weight, therefore It is laborious to manually adjust the height of the column, it is easy to over-operate, and has low adjustment accuracy

However, in the prior art, there is no technical means combining coarse adjustment and fine adjustment to precisely adjust the height of the occipital-mandibular belt
