Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a head support and protection dressing. Background Art

[0002] High intracranial pressure within a fixed-volume skull caused by large cerebral infarction, intracranial hemorrhage, and neoplastic lesions can rapidly lead to secondary brain injury, brain herniation, permanent neurological damage, or death. Decompressive craniectomy (hereinafter referred to as DC) effectively increases the volume of the brain under the scalp and relieves intracranial hypertension by temporarily removing part of the skull (unilateral or bilateral frontal, temporal, parietal, and occipital bones); secondly, it reduces ischemic damage by increasing cerebral blood flow and tissue oxygenation. Several studies have described DC as a life-saving intervention that can consistently reduce mortality and often improve prognosis, especially when performed in the early stages of the disease. Although there is increasing evidence that timely surgery can achieve better outcomes.

[0003] DC is a high-risk invasive treatment method. Usually, 3-5 disposable sterile dressings are used to cover the surgical wound after surgery, mainly to protect the wound and prevent incision infection.

[0004] Patients who have undergone decompressive craniectomy have lost the protection of the skull on the affected side of their heads, and the brain tissue itself is very fragile. Secondly, paradoxical extracranial hydrocephalus often occurs due to the disorder of cerebrospinal fluid circulation after decompressive craniectomy. Therefore, the protection of the brain tissue on the affected side of the decompressive craniectomy and the normalization of cerebrospinal fluid circulation should also be considered by medical staff after surgery.

[0005] Currently, the specifications of sterile dressings on the market are usually 9cm*10cm, 9cm*15cm, and 9cm*25cm, and are made of soft non-woven fabric.

[0006] Since the scalp incision for decompressive craniectomy is designed to be at least 12*15cm, the current dressing size is no longer sufficient to cover and protect the postoperative wound, and multiple dressings are required; in addition, current surgical accessories are rectangular, and due to the particularity of the surgical incision and surgical site of decompressive craniectomy, rectangular dressings cannot fit the head well, and in order to completely cover the wound, 3-5 dressings are generally used. This undoubtedly increases the cost burden on patients. Secondly, a moist and temperature-appropriate environment is required for the initial growth of the wound, and multiple dressings will leave "dead corners" and delay the growth of granulation tissue. On the other hand, the design of the dressing did not take into account issues such as brain tissue exposure and cerebrospinal fluid circulation, and it cannot protect the affected brain tissue well, thereby preventing re-injury and extracranial hydrocephalus caused by cerebrospinal fluid circulation disorders in the later stage, and there is a possibility of a second stage of surgery.

[0028] The utility model is described in detail below in conjunction with the accompanying drawings.

[0029] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0030] Example 1

[0031] In this embodiment, if Figure 1 As shown, a head support protective dressing comprises: a flexible layer 1, a support layer 2, an adhesive layer 3 and a dressing layer 4, wherein the flexible layer 1 is provided with a support layer 2 that can be shaped according to the shape of the patient's head, the support layer 2 is provided with a mesh structure, and the flexible layer 1 is provided with an adhesive layer 3 for bonding the patient's head and the dressing layer 4; the flexible layer 1 is made of non-woven fabric, which is soft in texture and can effectively buffer a part of external impact to protect the wound;

[0032] The support layer 2 is made of resin material, which provides support while being relatively light. The mesh structure can further reduce weight while ensuring support. At the same time, the special material resin is used, which can be shaped at high temperature to fit the patient's head shape and wound position to the maximum extent. After reaching room temperature, the resin cools and sets to provide support.

[0033] The adhesive layer 3 adopts a water-gel structure that can be repeatedly pasted. This material can still maintain stickiness in the case of repeated pasting. The dressing layer 4 that needs to be replaced regularly is pasted on the adhesive layer 3, which is conducive to rapid recovery of the wound;

[0034] In summary, a flexible layer 1 is used to cover a supporting layer 2 with supporting force, and an adhesive layer 3 is arranged at the bottom of the flexible layer 1. The adhesive layer 3 is used to stick the dressing on the patient's head to provide protection and support for the craniectomy surgery area. The shape and size are more in line with the wound on the head, which effectively reduces the number of dressings used, thereby alleviating the cost burden on patients, reducing the "dead corners" caused by multiple dressings, and reducing the possibility of incision infection.

[0035] Furthermore, the adhesive layer 3 is provided with a tearable protective film 5 to prevent the adhesive layer 3 from being contaminated with bacteria and other impurities before pasting. The protective film 5 is provided, and after the curvature of the supporting layer 2 is determined according to the patient's head, the protective film 5 is torn off, and the dressing is pasted on the patient's head. This can effectively shape the supporting layer 2 and prevent the adhesive layer 3 from carrying bacteria during adhesion, which may cause infection of the patient's wound.

[0036] Furthermore, the flexible layer 1, the supporting layer 2 and the adhesive layer 3 are configured as a flexible structure that can be cut according to the size of the affected area; since the patients' heads are of different sizes, curvatures and wound shapes, the patch adopts a cuttable flexible structure, and the patch can be cut according to the surgical wound conditions of different patients. Such a configuration can greatly save costs, and one patch can cover the wound without causing excess skin to stick due to the patch being too large. In the case of complex wounds, such as wounds close to the ears, the patch can be cut to avoid the ears for adhesion.

[0037] Further, such as Figure 4 As shown, it includes a seal 6 for sealing the cut flexible layer 1, support layer 2 and adhesive layer 3, and the seal 6 is arranged as a strip structure; the seal 6 is made of flexible plastic, adopts a "C"-shaped structure, has a certain clamping force, and is cut to a corresponding length according to the shape of the dressing to seal the edges of the cut dressing to prevent the hard support layer 2 from extending out to cause harm to the patient, or the flexible layer 1 is peeled off to cause the dressing to scatter as a whole.

[0038] Furthermore, it includes a Velcro layer 7, which is adhered to the adhesive layer 3; the Velcro layer 7 is provided with a plurality of fine barbs, and the Velcro layer 7 is adhered to the middle of the adhesive layer 3, so as to facilitate the subsequent adhesion of the dressing layer 4.

[0039] Furthermore, the dressing layer 4 is provided with Velcro corresponding to the Velcro layer 7; the size is set corresponding to the Velcro layer 7, and is set as a number of fine hairs. When the dressing layer 4 needs to be pasted or replaced, it is only necessary to peel off the dressing layer 4 and then paste the new dressing to the Velcro layer 7.

[0040] Further, such as Figure 3 As shown, the support layer 2 is fixedly connected at the intersection of the mesh structure; in order to prevent the support layer 2 from being displaced during use or after cutting, resulting in the instability of the mesh structure and insufficient support for the affected area.

[0041] Furthermore, a barb structure is provided on the surface of the support layer 2. Such a configuration allows the support layer 2 to hook onto the flexible layer 1 made of non-woven fabric, thereby preventing relative displacement between the support layer 2 and the flexible layer 1, thereby ensuring the support of the dressing and ensuring continuous and stable protection of the patient's wound.

[0042] Further, such as Figure 2 As shown, the flexible layer 1, the support layer 2 and the adhesive layer 3 are provided with notches 8, and the notches 8 can be cut with a cutting knife after cutting. Since the head is an arc-shaped surface, it is difficult for a complete patch to fit the head completely, so a notch 8 is provided at the edge of the patch so that it can fit the head better when fitting.

[0043] Furthermore, a waterproof layer 9 is arranged on the outside of the flexible layer 1; the waterproof layer 9 is arranged on the outermost side of the flexible layer 1, which can effectively prevent external water from penetrating into the wound, causing infection in the wound and increasing unnecessary treatment process.

[0044] Embodiment 2

[0045] On the basis of Example 1, the support layer 2 is made of a memory alloy. When changing the dressing or removing the dressing to check the wound recovery, it is inevitable to apply external force to the dressing to cause it to deform. Re-pasting may cause the dressing to not fit. Therefore, a memory alloy is used to heat the support layer 2 before re-application to restore it to its original curvature that matches the patient's head, so that it can completely fit the patient's head when applied for the second time.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
