Description

Technical Field

[0001] The utility model relates to the technical field of head protection after craniocerebral surgery, in particular to a head protection device after craniocerebral surgery. Background Art

[0002] In clinical practice, craniocerebral surgery is generally performed when a patient has craniocerebral injury or when a patient's brain tumor is removed. Generally, a U-shaped incision is made on the patient's scalp at the affected part, and then several holes are made on the skull. After the corresponding skull is removed, medical operations are performed, and then the skull is put back to suture the wound. After craniocerebral surgery, a drainage tube is often left in place. During the drainage process, a protective head cap is usually worn on the patient's head to better compress the dressing attached to the patient's scalp wound.

[0003] Publication number "CN215192646U" provides a postoperative head protection device for brain surgery. When in use, the buffer device corresponding to the injured part can be removed according to the location of the patient's head surgery. When removing, since the metal base is connected to the magnetic limit groove by magnetic attraction, the buffer device can be removed by applying force on both sides, thereby reducing the risk of damaging the surgical site during collision.

[0004] However, the above technical solutions and the prior art have the following defects:

[0005] Although the head protection device can provide buffering protection for the head after surgery through the buffer device, the spring in the buffer device will apply an extrusion force to the shock-absorbing plate through the connecting rod during actual use, causing the shock-absorbing plate to squeeze the wearer's head. Although the lower end face of the shock-absorbing plate is provided with a rubber pad, the extrusion force will increase the pain in the wearer's head, which is not in line with actual application scenarios. The head protection cap in the prior art is not provided with a corresponding drainage tube lead-out structure, resulting in the drainage tube used during use can only be led out through the lower periphery of the head protection cap, which will compress the drainage tube, making it easy to bend under pressure, resulting in the internal bending position being blocked and the drainage being interrupted. The practicality needs to be improved. Utility Model Content

[0038] In a further embodiment of the utility model, by installing a first thermal insulation layer 302 and a second thermal insulation layer 304, the thermal insulation property of the protective outer cover 100 is improved, so that the protective outer cover 100 can keep the patient's head warm during postoperative transportation, outdoor examinations, etc., and the protective inner pad 301 not only has good moisture absorption and moisture dissipation properties, but also can assist in pressing and limiting the head incision dressing to prevent the head incision dressing from falling off easily.

[0039] The insulation component 300 includes a first insulation layer 302 and a second insulation layer 304. The second insulation layer 304 is bonded to the inside of the protective outer cover 100. The outer surface area of ​​the second insulation layer 304 is the same as the inner wall area of ​​the protective outer cover 100. The second insulation layer 304 is made of aerogel. The second insulation layer 304 made of aerogel not only has good thermal insulation properties but also has light weight. The inner wall of the second insulation layer 304 is bonded to the first insulation layer 302. The first insulation layer 302 is made of medical absorbent cotton. The outer surface area of ​​the first insulation layer 302 is the same as the inner wall area of ​​the second insulation layer 304. The first insulation layer 302 made of medical absorbent cotton not only has a certain insulation capacity but also has good hygiene. The left and right end faces and the front and rear end faces of the first insulation layer 302 and the second insulation layer 304 are both provided with first through holes (not shown in the figure). The first through holes facilitate the external drainage tube to be inserted into the first insulation layer 302 and the second insulation layer 304 respectively.

[0040] The inner wall of the support frame 202 is attached with a protective inner pad 301, and the protective inner pad 301 is a mesh structure. The material of the protective inner pad 301 is medical gauze. The protective inner pad 301 with a mesh structure and made of medical gauze not only has good moisture absorption and moisture dissipation properties, but also can assist in pressing the head incision dressing to prevent the head incision dressing from falling off easily. The left and right end faces and the front and rear end faces of the protective inner pad 301 are all provided with an internal second through hole (not shown in the figure), and the size of the internal through hole is the same as the size of the internal insertion through hole 206, and the internal through hole is convenient for the outside to The drainage tube is inserted into the protective inner pad 301, and a plurality of weight-reducing cavities 305 are opened inside the first thermal insulation layer 302. The plurality of weight-reducing cavities 305 can further reduce the dead weight of the first thermal insulation layer 302. A fixing screw 303 is installed on the lower side of the inner part of the protective outer cover 100, and fixing screw holes 306 are symmetrically opened on the left and right sides and the front and back sides of the bottom support ring 208, and the fixing screw holes 306 are meshed with the fixing screws 303. The meshed fixing screw holes 306 and fixing screws 303 facilitate the disassembly and assembly of the protective outer cover 100, the first thermal insulation layer 302 and the second thermal insulation layer 304.

[0041] Working principle: After the patient undergoes cranial surgery, the medical staff first fits the dressing to the incision on the head, and then wears the device on the head through the first elastic fixing belt 400, the second elastic fixing belt 600 and the connecting buckle 500, so that the device can protect the patient's head. During this process, the protective inner pad 301 made of medical gauze not only has good moisture absorption and moisture dissipation properties, but also can assist in pressing and limiting the head incision dressing to prevent the head incision dressing from falling off easily. The first thermal insulation layer 302 and the second thermal insulation layer 304 make the thermal insulation of the protective outer cover 100 better, so that the protective outer cover 100 can keep the patient's head warm during postoperative transportation, outpatient examinations, etc., and the multiple weight-reducing cavities 305 can further reduce the dead weight of the first thermal insulation layer 302. The device is more portable to use; at the same time, the bottom support ring 208, the support frame 202 and the connecting round block 201 can protect the patient's head, and the first annular rib 203, the second annular rib 204, the third annular rib 205 and the connecting support bar 207 can further increase the protection area of ​​the support frame 202. At the same time, the external through hole 209 and the internal through hole 206 also facilitate the external drainage tube at the incision of the patient's head to be inserted into the protective outer cover 100 and the support frame 202 respectively, so as to avoid the external drainage tube being compressed by the protective outer cover 100 or the support frame 202 and the bottom support ring 208 during use, so that it is easy to be compressed and bent, resulting in the internal bending position being blocked and the drainage being interrupted. At a later stage, medical personnel only need to unfasten the connecting buckle 500 to remove the device.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
