[0031] In the existing technology, to prevent pressure injuries to the patients' ears during surgery, medical staff usually place dressing pads on the ears. However, as the head moves continuously during the operation, the dressing is prone to falling off, wrinkling, or becoming ineffective due to the patient's sweat, making it difficult to achieve stable protection.
[0032] Based on the above problems in the prior art, the present invention provides a device for preventing auricular pressure injury, such as Figure 1 and Figure 3As shown, the device for preventing auricle pressure injury includes: a mask body 100, which is an ellipsoid and has a mounting hole 110 on one side of the mask body 100; the mask body 100 includes a contact layer 121 arranged on the inner side, and a pressure-sensitive adhesive 123 is coated on the side of the contact layer 121 facing the inner cavity of the mask body 100; an absorption layer 122, which is laminated on the contact layer 121; and an anti-seepage layer 130, which is laminated on the outer side of the absorption layer 122.
[0033] The present invention can cover the patient's ear by providing a mask body 100 with a mounting hole 110, thereby isolating the ear from contact with the side of the skull and relieving pressure. The contact layer 121 coated with a pressure-sensitive adhesive 123 ensures that the mask body 100 is flat and wrinkle-free, and stably fixes the mask body 100 on the ear. The absorption layer 122 can absorb the patient's sweat. The present invention is low-cost and easy to use, and can prevent pressure damage caused by long-term pressure on the ear during surgery.
[0034] In the above embodiment, if Figure 1 As shown, the main body of the device for preventing auricle pressure injury of the present invention is a mask body 100, which is in the shape of an ellipsoid, and its length and width dimensions are adapted to the length and width dimensions of the human ear. During specific production, those skilled in the art can preset multiple models according to the average size of the human ear at different stages to adapt to patients with different ear sizes. A mounting hole 110 is provided on one side of the mask body 100, and the mounting hole 110 is intersected with the inner cavity of the mask body 100. In actual use, the patient's ear is mounted through the mounting hole 110, and the ear can be mounted inside the mask body 100, so that during the operation, the two sides of the ear are respectively isolated from the bed surface and the skull side by the mask body 100, and the pressure is relieved, so as to achieve the effect of avoiding pressure injury.
[0035] In this embodiment, if Figure 2 and Figure 3As shown, the mask body 100 is specifically a multi-layer structure. From the inside of the mask body 100 to the outside of the mask body 100, the contact layer 121, the absorption layer 122, and the anti-seepage layer 130 are respectively provided. The contact layer 121 is used to contact the patient's ear. In this embodiment, to ensure stable installation of the mask body 100 at the patient's ear and prevent wrinkles on the mask body 100 due to movement of the patient's head during surgery, a pressure-sensitive adhesive 123 is also coated on the contact layer 121 on the side facing the inner cavity of the mask body 100. The full name of the pressure-sensitive adhesive 123 adhesive is pressure-sensitive adhesive, also commonly known as self-adhesive adhesive, or simply pressure-sensitive adhesive 123. Common pressure-sensitive adhesive 123 products include three categories: pressure-sensitive adhesive 123 tape, pressure-sensitive adhesive 123 label paper, and pressure-sensitive adhesive 123 sheets. The components are adjusted to achieve better product performance. In this embodiment, the contact layer 121 coated with pressure-sensitive adhesive 123 is fitted with the corresponding part of the patient's ear, which not only fixes the installation position of the mask body 100 but also maintains the flatness of the mask body 100, thereby effectively preventing the occurrence of pressure injuries during surgery.
[0036] The absorption layer 122 is fitted on the contact layer 121. The absorption layer 122 is used to absorb sweat from the patient's ears and store the sweat to keep the patient's ears dry. This can prevent the patient from developing eczema due to long-term pressure and sweat penetration during surgery, and can also prevent the mask body 100 from being damaged by sweat; the anti-seepage layer 130 is provided on the outside of the absorption layer 122. Its main function is to prevent the absorbed sweat from seeping out from the outside of the mask body 100, thereby ensuring the dryness of the patient's ears and the corresponding positions on the skull side. In this embodiment, the anti-seepage layer 130 also has the effect of increasing the sliding properties between the skull side and the ear, and preventing the ear and the skull side skin from being fitted in one state for a long time when the head moves during surgery.
[0037] In a specific embodiment, in order to prevent the coverage area of the pressure-sensitive adhesive 123 from affecting the absorption of the patient's sweat by the absorbent layer 122, the pressure-sensitive adhesive 123 can also be arranged in a dotted manner in this embodiment so that there is a certain avoidance space between adjacent pressure-sensitive adhesive 123 points, so that sweat can pass through and be absorbed by the absorbent layer.
[0038] In another embodiment of the present invention, the contact layer 121 can be specifically configured as a polyurethane film layer. Polyurethane film is a polymer material with multiple properties. It is a film made of polyurethane (PU). Polyurethane is a polymer compound formed by the addition polymerization of polyisocyanates and polyhydroxy polymers. It has excellent properties such as wear resistance, high mechanical strength, high elasticity, aging resistance, and corrosion resistance. Polyurethane film is widely used in the medical industry due to its high air permeability, biocompatibility, and good bacterial barrier properties. In this embodiment, by configuring the contact layer 121 as a polyurethane film layer, the area in contact with the patient's ear can be made more skin-friendly, and has elastic and breathable properties, which can effectively improve the patient's wearing comfort.
[0039] In another embodiment of the present invention, the absorption layer 122 is a water-absorbing resin absorption layer 122. The water-absorbing resin, also known as a super absorbent resin or hydrogel, is a polymer material with a special water absorption capacity. This resin can quickly absorb and retain a large amount of water, and its water absorption capacity can reach hundreds or even thousands of times its own weight. The water-absorbing resin usually contains strong hydrophilic groups, such as hydroxyl groups and carboxyl groups. These groups give the resin a high affinity for water and can form hydrogen bonds with water molecules, thereby achieving rapid water absorption. It has high water absorption, high water absorption rate, high water retention, and ammonia absorption. It can absorb and lock in moisture, and can also achieve a deodorizing effect. In this embodiment, the absorption layer 122 absorbs sweat to keep the patient's ears fresh and comfortable.
[0040] In the above embodiment, the absorption layer 122 can be specifically provided with multiple layers. The multi-layer absorption layer 122 structure can improve the performance of absorbing sweat on the one hand, and on the other hand, further improve the effect of isolating the auricle and the skin on the side of the skull, thereby achieving a better pressure relief effect. In this embodiment, the specific number of the absorption layer 122 is not limited in this application, and those skilled in the art can set it according to actual usage requirements.
[0041] In another embodiment of the present invention, Figure 2 and Figure 3As shown, the above-mentioned anti-seepage layer 130 is specifically composed of a first layer 131 and a second layer 132. The first layer 131 is coated with a pressure-sensitive adhesive 123 on the side facing away from the inner cavity of the mask body 100. The second layer 132 is tightly attached to the first layer 131 through the pressure-sensitive adhesive 123 coated on the first layer 131. The second layer 132 should be waterproof to prevent sweat absorbed by the absorbent layer 122 from leaking out of the second layer 132. In addition, the second layer 132 should be made of a smooth material to facilitate relative movement between the patient's auricle and the skin on the side of the skull when the patient's head moves during surgery, thereby alleviating the feeling of pressure. The provision of the anti-seepage layer 130 can keep the area between the patient's auricle and the skin on the side of the skull dry, preventing eczema caused by sweat accumulation.
[0042] In the above embodiment, the first layer 131 can be specifically formed of a polyurethane film layer. The properties of the polyurethane film layer have been described in detail above. The advantages of using the first layer 131 as a polyurethane film layer include, on the one hand, wrapping the absorbent layer 122, and, on the other hand, ensuring comfort when the skin on the skull side contacts the mask 100 through its elasticity and wear resistance. The second layer 132 can be specifically formed of a release paper layer. Release paper, also known as silicone oil paper or anti-adhesive paper, is a paper base coated with a special material (such as silicone oil or other release agent). Its primary function is to prevent other materials from adhering to the paper surface during processing. Release paper is widely used in various industrial fields and has the following main characteristics: it prevents adhesion, provides protection, is easy to process, is heat-resistant, chemically stable, recyclable, and has good customization. Therefore, in this embodiment, by using the second layer 132 as a release paper layer, a certain degree of leakage prevention is achieved. Its anti-adhesion function also maintains a smooth surface between the auricle and the skin on the skull side, thereby facilitating posture adjustment during surgery.
[0043] In a specific embodiment, Figure 2 and Figure 3 As shown, the above-mentioned pressure-sensitive adhesive 123 should be set on the contact layer 121 at a position corresponding to the back of the patient's ear. The advantage of this arrangement is that, on the one hand, the back of the ear has a complete skin surface, and the pressure-sensitive adhesive 123 fits the back of the ear for better stability. At the same time, the skin on the back of the ear is close to a plane, which is conducive to maintaining the flatness of the mask body 100 and avoiding wrinkles. On the other hand, the front side of the ear does not need to fit with the contact layer 121, providing a larger space for breathability, avoiding the ear hole being covered and causing discomfort caused by changes in air pressure in the ear.
[0044] In another embodiment of the present invention, Figure 1As shown, a positioning ring 200 is further provided on the cover body 100 at a position corresponding to the mounting hole 110. The positioning ring 200 is made of an elastic material, specifically rubber, silicone and the like. The positioning ring 200 is intersected with the cover body 100. In actual use, the positioning ring 200 is used to engage the auricle, so that the cover body 100 is stably mounted on the ear.
[0045] Furthermore, in the specific settings, such as Figure 1 As shown, one side of the positioning ring 200 is further provided with a relief portion 210, which is recessed along a predetermined arc toward the inner side of the positioning ring 200. In actual setting, the relief portion 210 is set corresponding to the position behind the ear. Figure 4 Since the auricle of the human ear faces obliquely backward, the provision of the clearance portion 210 can cooperate with the shape of the rear of the human ear to achieve the effect of making the positioning ring 200 more snugly fixed at the base of the ear.
[0046] Based on the above embodiments, Figure 4 As shown, the actual use process of the device for preventing auricular pressure injury of the present invention is as follows:
[0047] Before the operation, the medical staff determines the side of the patient's head that needs surgery and the side that is oppressed, selects a suitable model of auricular pressure injury prevention device and puts it on the ear on the oppressed side, and puts it on the ear through the mounting hole 110 so that the side of the positioning ring 200 with the yield portion 210 corresponds to the back of the ear. After the mask 100 completely covers the ear, press the mask 100 and the ear so that the pressure-sensitive adhesive 123 on the internal contact layer 121 of the mask 100 fits and is fixed to the back of the patient's ear, thus completing the installation of the auricular pressure injury prevention device.
[0048] During surgery, the mask body 100 composed of the contact layer 121, the absorption layer 122 and the anti-seepage layer 130 isolates the patient's ear from the side of the skull and the bed surface and relieves pressure. During the operation, it absorbs sweat and keeps the patient fresh, and prevents the mask body 100 from falling off and wrinkling, effectively avoiding the occurrence of pressure injuries.
[0049] Based on the above embodiments, the present invention also provides a surgical protective device, which includes the device for preventing auricular pressure injuries in the above embodiments, and the device for preventing auricular pressure injuries includes: a cover body, which is ellipsoidal and has a mounting hole on one side of the cover body; the cover body includes a contact layer arranged on the inner side, and a pressure-sensitive adhesive is coated on the side of the contact layer facing the inner cavity of the cover body; an absorption layer, which is bonded to the contact layer; and an anti-seepage layer, which is bonded to the outer side of the absorption layer. The present invention can cover the patient's ear by providing a cover body with a mounting hole, thereby isolating the ear from contact with the side of the skull and relieving pressure. The contact layer coated with pressure-sensitive adhesive can ensure that the cover body is flat and wrinkle-free, and can also stably fix the cover body on the ear. The absorption layer can absorb the patient's sweat. The present invention is low-cost and easy to use, and can prevent pressure injuries caused by long-term pressure on the ear during surgery.
[0050] In summary, the present invention provides a device for preventing pressure injuries to the auricle and a surgical protective instrument, wherein the device for preventing pressure injuries to the auricle specifically includes: a cover body, the cover body is ellipsoidal, and a mounting hole is provided on one side of the cover body; the cover body includes a contact layer provided on the inner side, and a pressure-sensitive adhesive is coated on the side of the contact layer facing the inner cavity of the cover body; an absorption layer, the absorption layer is bonded to the contact layer; and an anti-seepage layer, the anti-seepage layer is bonded to the outer side of the absorption layer.
