PATENT SPECIFICATION FOR THE INVENTION ENTITLED: A PROTECTIVE DEVICE USED AFTER HEAD DECOMPRESSION SURGERY

The invention is described in the following statement:-

A PROTECTIVE DEVICE USED AFTER HEAD DECOMPRESSION SURGERY TECHNICAL FIELD

The present invention relates to the technical field of medical equipment, in particular

to a protective device used after head decompression surgery.

BACKGROUND

Decompressive craniectomy is applied in various diseases of central nervous system

such as craniocerebral injury, cerebrovascular disease, brain tumor, and has become a

routine operation in neurosurgery, which can effectively reduce intracranial pressure and

save lives. At the same time, postoperative care is also particularly important, and pressure

relief in the area of the surgical bone flap is one of the important contents of postoperative

care. Generally, in clinical nursing work, it is often only to mark the " pressure

forbidden" mark on the dressing of the surgical area, instead of using protective equipment

that can avoid pressure forbidden or resist pressure for actual protection. Therefore, the

current existing nursing care cannot play an effective protective role, and in order to avoid

the risk of accidental touching of the patient's surgical area, this application has designed a

head protective cap with hard plastic bone fragments, in which, the hard plastic bone

fragment can effectively protect the bone flap area of the head surgery, thereby protecting

the safety of the patient.

SUMMARY

In view of the foregoing, it is necessary to provide a protective device for head

decompression surgery. The head protective cap can effectively protect the bone flap area

of the head surgery without being restricted by the position of the bone flap.

In order to achieve the purpose, the technical scheme adopted by the invention is as

follows: the protection device for head decompression surgery comprises an inner liner and

a fixed edge. The inner lining layer is in the shape of a hollow mesh and fits the head, and

the fixing edge is fixed on the lower edge of the inner lining layer, and forms the cap body

of the head protective cap with the inner lining layer. Four sliding rails are arranged on the

upper side of the fixed edge at intervals, the four sliding rails are arranged in four directions

on the fixed edge and are not connected to each other, and the sliding rails are ports that

penetrate the upper and lower sides of the fixed edge or the upper and outer sides. The

device comprises a hard plastic bone piece, a four-bone piece fixing belt and four clamping

pieces also. The hard plastic bone pieces are fixedly arranged on the outer side of the inner

lining layer through four bone piece fixing belts. The four bone piece fixing belts are

respectively arranged on four sides of the hard plastic bone piece, one end of the four bone

piece fixing belts is connected with the hard plastic bone piece, and the other end of the

four bone piece fixing belts respectively passes through the four sliding rails and extends

out of the fixing edge. The bone piece fixing belt and the fixing edge are slidingly

connected. Each clamping piece corresponds to a sliding rail, the clamping piece is inserted

from the outer side of the fixed edge to the inside of the fixed edge, and the sliding rail is

sealed inside. The clamping piece is slidingly connected with the fixing edge, and the slide rail is sealed in a sliding mode to clamp a bone piece fixing belt on the slide rail or is opened to loosen the bone piece fixing belt.

Further, the bone piece fixing belt and the hard plastic bone piece are detachably

connected.

Further, the hard plastic bone piece has a semi-elliptical arc structure, and a plurality

of air-permeable through holes are opened on it.

Further, the inner lining layer is made of cotton material and has elasticity.

Further, the head protection cap further includes a visor, which is detachably mounted

on the fixed edge and has a telescopic structure.

Further, the head protection cap further includes an outer lining layer, which covers

the inner lining layer and the outer side of the hard plastic bone fragment, and the lower

edge is fixed on the fixed edge by a HOOK&LOOP or a zipper.

opposite sides of the fixing edge respectively.

Compared with the prior art, the present invention has the following beneficial effects:

1. In the present invention, a hard plastic bone fragment is set on the cap to cover the

bone removal flap area of the head surgery, so that the bone removal flap area will not be

touched or squeezed by the outside, thereby effectively protecting the safety of the patient.

Furthermore, the hard plastic bone piece is placed on the cap body through the bone piece

fixing belt, and the position of the hard plastic bone piece placed on the cap body is adjusted

by the sliding of the bone piece fixing belt on the slide rail, so that the hard plastic bone

piece can adapt to different bone flap removal areas in head surgery, and the application

range of the head protection cap is improved. In addition, the invention also fixes the

adjusted bone plate fixing belt through the clamping piece arranged on the fixing edge,

thereby fixing the hard plastic bone plate, preventing the hard plastic bone plate from

shifting in the use process and failing to effectively protect the bone flap removal area of

the head surgery of the patient.

2. The designed head protection cap after decompressive craniectomy can effectively

protect the craniectomy area of patients, and has simple structure, convenient use, wide

application range and good practicability.
