Description

Technical Field

[0001] The utility model belongs to the field of medical auxiliary instruments, in particular to a compression device for a post-auricular and posterior cranial fossa incision. Background Art

[0002] Subcutaneous fluid accumulation after craniotomy is a common complication of craniotomy. It can directly affect the patient's recovery and, in severe cases, lead to intracranial infection, endangering the patient's life.

[0003] Postoperative neurosurgery procedures involving retrosigmoid, paramedian, and median cerebellar incisions are prone to subcutaneous effusion due to the difficulty in effectively compressing the wound. Currently, headbands are commonly used for wound compression, but due to their limited size, they are not specifically designed for compression of postauricular and posterior cranial fossa incisions. Consequently, headbands struggle to fully compress the wound area and can compress the ear as well, potentially causing ear pain and discomfort, or even ear damage. Therefore, there is an urgent need for a compression device specifically designed for postauricular and posterior cranial fossa incisions that does not compress the patient's ear. Utility Model Content

[0004] The utility model discloses a compression device for a post-auricular and posterior cranial fossa incision, which mainly solves the problem that after a patient undergoes craniotomy, a hairband is often used to compress the wound, which cannot achieve a good compression effect and easily causes ear pain and discomfort to the patient.

[0005] To achieve the above-mentioned purpose, the present invention provides a compression device for the incision behind the ear and in the posterior cranial fossa, comprising a compression body and fixing straps arranged at both ends of the compression body. A compression air cushion for compressing the incision behind the ear and in the posterior cranial fossa is arranged on the inside of the compression body, and earmuffs are arranged on both sides of the compression body to avoid compressing the ear.

[0006] Preferably, the compression body and the fixing belt are both made of soft, breathable elastic materials.

[0007] Preferably, the fixing belts are detachably connected to each other.

[0008] Preferably, the earmuff is provided with a plurality of ventilation holes.

[0009] Preferably, a soft, skin-friendly cushion strip is provided at the connection between the earmuff and the compression body.

[0010] Preferably, the compression body is provided with an inflation port, the inflation port is communicated with the compression air cushion pipeline, and a one-way air valve is provided in the inflation port.

[0011] Preferably, a non-slip soft rubber is provided outside the inflation port.

[0012] Preferably, a plurality of the compression air cushions are provided, and each compression air cushion is connected to an inflation port for independent inflation.

[0013] Preferably, the compression body is provided with a shaping plate that fits the curvature of the back of the human head.

[0014] The technical solution provided by the utility model has at least the following technical effects:

[0015] The utility model discloses a compression device for incisions behind the ear and in the posterior cranial fossa. After surgery on a patient behind the ear and in the posterior cranial fossa, a compression body is placed against the patient's incision, and the patient's ears are aligned with the earmuffs provided on both sides of the compression body. Fixing straps provided at both ends of the compression body are connected from above the eyebrows to fix the overall structure. Compared with the existing method of using a hairband to compress the wound, this device is specially designed for incisions behind the ear and in the posterior cranial fossa. The compression body has a larger compression range for incisions behind the ear and in the posterior cranial fossa, and the earmuffs can also cover the patient's ears to avoid ear pain and discomfort, or even ear damage to the patient.

[0022] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

[0023] In the description of the embodiments of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0024] Reference Figure 1 This embodiment discloses a compression device for behind-the-ear and posterior cranial fossa incisions, comprising a compression body 1, fixed straps 2 disposed at both ends of the compression body 1, a compression air cushion 3 disposed on the inner side of the compression body 1 for compressing the behind-the-ear and posterior cranial fossa incisions, and earmuffs 11 disposed on both sides of the compression body 1 to prevent compression of the ears. After a patient undergoes a neurosurgery procedure such as a retrosigmoid sinus, paramedian cerebellar, or median cerebellar incision, the patient's postoperative incision is often located behind the ear or near the posterior cranial fossa. The patient's injured area is placed on the compression body 1, and the earmuffs 11 on both sides can completely cover the patient's ears, preventing them from being compressed and causing discomfort. Both the compression body 1 and the fixed straps 2 are made of a soft, breathable, elastic material. The compression body 1 can better compress the patient's incision, and the fixed straps 2 can also be adjusted to a certain length based on the patient's head circumference. The fixed straps 2 at both ends of the compression body 1 are detachably connected. In this embodiment, Velcro is used for connection, allowing for further adjustment based on the patient's head circumference.

[0025] To ensure that the patient's hearing is not affected, the earmuff 11 is equipped with multiple ventilation holes. These holes also increase air circulation inside and outside the earmuff 11 during use, preventing the patient's ears from becoming stuffy and increasing patient comfort. A soft, skin-friendly padding strip is installed at the connection between the earmuff 11 and the compression body 1. When the compression body 1 compresses the patient's surgical incision, it drives the compression body 1 and the earmuff 11 to compress the skin around the ear. The padding strip relieves the pressure of the compression body 1 and the earmuff 11 on the skin around the ear, increasing patient comfort.

[0026] like Figure 3 、 Figure 4As shown, in order to adjust the pressure of the compression air cushion 3, an inflation port 12 is provided on the compression body 1, and the inflation port 12 is connected to the pipeline of the compression air cushion 3, and a one-way air valve is provided in the inflation port 12. When in use, a syringe barrel is used to connect to the inflation port 12. When the syringe barrel is pushed and pulled, air enters the compression air cushion 3 through the inflation port 12 and the inflation pipeline 121, increasing the pressure in the compression air cushion 3, thereby increasing the pressure of the compression air cushion 3 on the surgical incision; if the medical staff over-inflates the air during use, they can also use the syringe barrel to suck out some of the gas to reduce the pressure in the compression air cushion 3, thereby reducing the pressure of the compression air cushion 3 on the patient's surgical incision. The pressure of the compression air cushion 3 is adjustable. In addition, a non-slip soft rubber 122 is provided on the outside of the inflation pipeline 121 to improve the comfort of the patient. Furthermore, since most patients only have surgical incisions on one side of their head, multiple compression air cushions 3 are provided to more precisely compress the surgical incision. Each compression air cushion 3 is connected to an inflation port 12 for independent inflation. During use, a syringe is used to increase the pressure within the inflated air cushion corresponding to the patient's surgical incision. This compresses only the area corresponding to the surgical incision, leaving the rest of the skin unaffected, thereby improving patient comfort.

[0027] Reference Figure 2 In order to better compress the patient's surgical incision and prevent subcutaneous edema in the patient, a shaping plate 21 that fits the curvature of the back of the human head is provided in the compression body 1. The shape of the shaping plate 21 fits the curvature of the back of the human head and is embedded in the middle position of the compression body 1. It is wrapped by the compression body 1 on all sides and is light and thin, which does not affect the patient's comfort. When in use, when the inflatable air cushion compresses the corresponding surgical incision area, the shaping plate 21 has a certain shaping effect, which can assist the inflatable air cushion in compressing the surgical incision area. And because the shaping plate 21 has a fixed shape, the compression bodies 1 on both sides fit the patient's skin, and more comprehensive compression can be performed on the wounds of the compression bodies 1 on both sides.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
