Description

Technical Field

[0001] This utility model relates to the field of medical protective equipment technology, specifically to a protective cover for skull defects. Background Technology

[0002] In modern medicine, decompressive craniectomy is commonly used to treat patients with severe traumatic brain injury. Three to four months after decompressive craniectomy, cranioplasty can be performed to repair the skull defect. During this period, the defect area of ​​the patient's skull lacks the support and protection of the skull, requiring complex and meticulous care to prevent damage to brain tissue. Currently, existing technology offers 3D-printed, custom-made "protective caps" for each patient, which can better fit the skull defect area, protecting brain tissue, preventing hydrocephalus and subdural effusion, and promoting brain tissue repair. This helps patients return to normal life as soon as possible and provides a strong guarantee for their safe and stable passage through the skull defect period.

[0003] Although a shape matching the skull defect can be obtained through 3D printing, it is very uncomfortable for patients to wear a completely rigid shell; it is also difficult to fix it again, it is easy to shift, and there is a lack of internal cushioning space; it also causes a lot of inconvenience in daily life, especially during sleep, wearing a rigid protective cap makes it difficult for most patients to fall asleep, affecting their health.

[0004] In summary, there is an urgent need to design a protective shield for skull defects that overcomes the aforementioned problems. Utility Model Content

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0036] Please see Figures 1 to 5 A protective shield for skull defects, comprising:

[0037] The hat body is made of soft fabric 1;

[0038] The cap body 1 includes an inner layer 11 and an outer layer 12 sewn together at their lower edges. A fixing ring 2 is fixedly provided at the lower edge between the inner layer 11 and the outer layer 12. An arc-shaped top cover 3 is fixedly provided at the upper end between the inner layer 11 and the outer layer 12. An arc-shaped protective cover 4 is detachably connected between the top cover 3 and the fixing ring 2. The fixing ring 2 and the top cover 3 can be made of relatively thin plastic and have a certain degree of rigidity. However, the fixing ring 2 is relatively narrow and relatively long overall, which can produce bending deformation and facilitates fitting and fixing to the head.

[0039] The protective cover 4 is multiple, and after the multiple protective covers 4 are connected with the top cover 3 and the fixing ring 2, the cap body 1 is opened to form a shape that matches the head; the protective cover 4 can be installed according to the location of the patient's defect, so as to cover and protect the skull defect through the protective cover 4, and can provide targeted protection for the defect. For the undamaged area, it is more comfortable to directly contact the soft cap body.

[0040] The outer layer 12 is provided with an openable operating port 121. By opening the operating port 121, it is convenient to install and remove the protective cover 4. After installation, the operating port 1212 can be closed.

[0041] Preferably, the operating opening 121 is a circular slit formed around the middle of the outer layer 12. Matching hook and loop fasteners 122 and velvet fasteners 123 are sewn onto the upper and lower ends of the outer layer 12, respectively. The hook and loop fasteners make opening and closing easier and prevent hard objects from pressing against the patient's head. Of course, the opening and closing of this operating opening can also be achieved by using a thin zipper, snap fastener, or strap, as long as it does not press against the patient's head. The height of the breathable pressure-reducing pad 5 can be set higher than the height of each opening and closing component, so the patient will not feel any hard objects when lying down.

[0042] Preferably, the lower rear end of the cap body 1 has a notch 13, and the fixing ring 2 is broken at the notch 13. A first adjusting band 21 and a second adjusting band 22 are integrally connected to both ends of the fixing ring 2. The first adjusting band 21 and the second adjusting band 22 are each uniformly provided with multiple matching fasteners 211 and fastening holes 221. The connection position of the first adjusting band 21 and the second adjusting band 22 can be adjusted according to the patient's head circumference, thus making the device suitable for patients with different head circumferences and improving the applicability of this protective cover.

[0043] Preferably, the protective cover 4 has plastic buckles 41 at its upper and lower ends, and the lower end of the top cover 3 and the upper end of the fixing ring 2 are respectively provided with slots 31 that match the plastic buckles 41. The protective cover 4 can be made of hard plastic, and the plastic buckles 41 can be inserted into the slots 31 by external pressure, thereby connecting the protective cover 4 with the top cover 3 and the fixing ring 2.

[0044] Preferably, a silicone pad 42 is provided on the inner surface of both the protective cover 4 and the top cover 3;

[0045] The silicone pad 42 on the protective cover 4 and the protective cover 4 are respectively provided with a number of ventilation holes 43 to improve the air permeability of the damaged part.

[0046] Preferably, a breathable pressure-reducing pad 5 is attached to the lower end of the inner layer 11 facing the outer layer 12.

[0047] Preferably, the inner layer 11 and the outer layer 12 at the upper end of the notch 13 are connected by needle and thread stitching.

[0048] Preferably, the inner surface of the fixing ring 2 is provided with a breathable soft pad strip 23.

[0049] In this invention, the silicone pad 42, the breathable pressure-reducing pad 5, and the breathable soft pad strip 23 can further increase the buffer space when the inner wall of the protective cover comes into contact with the patient's head, improving the comfort of the patient's head when wearing it. When the patient is sleeping, they can choose to lie on their side or back with their skull intact. The combination of the soft cap and the breathable pressure-reducing pad 5 can effectively reduce the pressure on the patient's head when sleeping, further improving the comfort of the patient when wearing the protective cover to sleep, without affecting the patient's sleep, and ensuring the patient's health.

[0050] The present invention has been further described above with reference to the embodiments, but the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
