Description

Technical Field

[0001] The invention belongs to the field of ice compress care, and in particular relates to a highly absorbent resin ice bag suitable for head and face. Background Art

[0002] Ice compress is a commonly used physical therapy in clinical practice. It constricts blood vessels, slows local metabolism, and inhibits inflammatory responses through the effect of low temperature, thereby effectively relieving swelling, pain, and fever. For example, patients with postoperative swelling of the head and face, cervical sprains, or high fever all require cold compresses to control symptoms.

[0003] Traditionally, ice packs are used to apply ice to the affected areas of the head and face.

[0004] However, traditional ice packs are mostly fixed in shape (square, round), which cannot adapt to the complex anatomical curves of the head and neck. They can easily cause pressure on the skin in sensitive areas of the face, causing discomfort to the patient and even local blood circulation disorders. They rely on melting ice to release cold energy, and the effective cold compress duration is short. They need to be changed frequently and are prone to frostbite on the skin. Summary of the Invention

[0005] The purpose of the present invention is to provide a highly absorbent resin ice pack suitable for the head and face, so as to solve the problems raised in the above-mentioned background technology that traditional ice packs are mostly fixed in shape, cannot adapt to the complex anatomical curves of the head and neck, rely on melting ice cubes to release coldness, and have a short effective cold compress duration.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A super absorbent resin ice pack suitable for the head and face comprises an ice pack main body, which comprises, from the inside to the outside, a silver ion-coated non-woven fabric, a temperature buffer layer, a temperature-slow-release core, an elastic memory layer, and a hot-air non-woven fabric. The temperature-slow-release core comprises a super absorbent resin layer for adsorbing a phase-change material.

[0008] Preferably, the temperature buffer layer is a microporous sponge or a silica gel grid.

[0009] Preferably, the elastic memory layer includes a shape memory polymer embedded between the temperature-slow-release core and the hot air non-woven fabric, and a memory alloy wire arranged on the outer edge of the shape memory polymer.

[0010] Preferably, the memory alloy wire is arranged in a strip shape, and the shape memory polymer is arranged in a mesh shape.

[0011] Preferably, the temperature-slow-release core further comprises dust-free paper arranged on the outside of the super absorbent resin layer, and a fluff pulp layer arranged on the inside of the super absorbent resin layer.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The present invention uses an elastic memory layer to allow the ice bag to adaptively bend with the movement of the head and neck, avoiding the stiffness of traditional ice bags. It bends in both directions along the longitudinal and transverse axes of the head and neck, fitting the cervical spine, back of the head and mandibular area, avoiding the oppressive feeling of traditional square or round ice bags. The super absorbent resin layer absorbs phase change material to extend the cold compress time, the microporous structure of the temperature buffer layer is used to disperse local pressure, and the outer layer of hot air non-woven fabric is combined with rapid moisture removal to synergistically reduce the risk of frostbite.

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0023] As attached Figure 1 、 2 , 3 and attached Figure 4 As shown:

[0024] Embodiment 1: This embodiment provides a highly absorbent resin ice pack suitable for the head and face, including an ice pack main body 1. The ice pack main body 1 includes a silver ion coated non-woven fabric 105, a temperature buffer layer 104, a temperature slow-release core 103, an elastic memory layer 102 and a hot air non-woven fabric 101 from the inside to the outside. The temperature slow-release core 103 includes a super absorbent resin layer 1032 for adsorbing phase change material.

[0025] Phase change materials include, but are not limited to, ethanol-ammonium chloride solution, sodium sulfate decahydrate, and n-octadecane.

[0026] Attachment Figure 4 The upper left center portion shows the main body 1 of the ice pack suitable for nasal injuries, which is applied to the triangular area of the patient's nose during use;

[0027] The upper right side shows the main body 1 of the ice pack suitable for conventional head cooling, which is applied to the patient's forehead during use;

[0028] The lower left side shows the main body 1 of the ice pack suitable for use after neck surgery. When in use, it is attached to the patient's neck to cover the side of the neck.

[0029] The lower right side shows the main body 1 of the ice pack suitable for the ear and parotid area, which is covered on the patient's ear through the through hole in the middle when in use.

[0030] When in use, the ice pack body 1 with a U-shaped curved surface is attached to the patient's affected area. The silver ion coated non-woven fabric 105 is a skin-friendly and antibacterial material. Its surface is coated with a silver ion antibacterial agent, which can reduce the accumulation of condensed water during ice application, inhibit bacterial growth, and reduce the risk of skin infection.

[0031] The temperature buffer layer 104 disperses the contact pressure between the temperature-releasing core 103 and the skin, preventing ice crystals from directly pressing on the capillaries and reducing the risk of frostbite.

[0032] The super absorbent resin layer 1032 is a polymer material with super water absorption capacity. It uses its property of forming a gel when in contact with water to absorb the ethanol-ammonium chloride solution to form a gel. It stores cold energy through the phase change latent heat of 304kJ / kg and cooperates with the phase change material to achieve slow release of cold energy. The ethanol-ammonium chloride solution is a refrigerant; the phase change time is extended by electrolysis.

[0033] The elastic memory layer 102 is located between the temperature-slow-release core 103 and the hot air non-woven fabric 101. It memorizes the initial shape of the ice pack body 1. When the ice pack body 1 is covered on the patient's skin, the elastic memory layer 102 will undergo elastic deformation simultaneously. After deformation, it uses its own memory properties to cause the ice pack body 1 to deform back to its initial shape, thereby making the ice pack body 1 completely fit the skin. When the patient's head and neck move, the ice pack body 1 can adaptively deform, reducing the sense of restraint.

[0034] Hot air non-woven fabric 101 is a highly soft and breathable non-woven fabric with a water vapor transmission rate of ≥2000g / m 2 24 hours, reducing skin friction irritation when handling the device, and quickly draining away condensation during ice application, maintaining a dry user experience.

[0035] Specifically, the temperature buffer layer 104 is a microporous sponge.

[0036] Specifically, the elastic memory layer 102 includes a shape memory polymer 1021 embedded between the temperature-slow-release core 103 and the hot air non-woven fabric 101 , and a memory alloy wire 1022 disposed on the outer edge of the shape memory polymer 1021 .

[0037] The shape memory polymer 1021 adaptively deforms with the movement of the head and neck to reduce the feeling of restraint, and the memory alloy wire 1022 is distributed along the edge of the ice pack to provide structural support and enhance dynamic fit.

[0038] Specifically, the memory alloy wire 1022 is arranged in a strip shape, and the shape memory polymer 1021 is arranged in a mesh shape.

[0039] The memory alloy wire 1022 is embedded in the edge of the ice pack in a strip shape. Utilizing its superelasticity and shape memory effect, the ice pack can quickly return to its preset shape after being deformed by external forces (such as head movement), preventing the ice pack from twisting or collapsing. The strip distribution can also provide directional support along the anatomical curves of the head and neck (such as the cervical spine and mandibular line), allowing the ice pack to maintain uniform contact with the skin during movement, reducing the risk of slipping.

[0040] The shape memory polymer 1021 mesh setting has porous elasticity, allowing the ice pack to stretch or bend slightly with head and neck movements (such as turning or lowering the head), avoiding the stiffness of traditional ice packs and improving wearing comfort;

[0041] The memory alloy wire 1022 provides rigid support to maintain the overall shape, while the shape memory polymer 1021 provides flexible fit. The combination of the two achieves dynamic stability, which not only maintains the integrity of the ice pack structure but also adapts to the complex needs of human activities.

[0042] The memory alloy wire 1022 may be made of nickel-titanium alloy, and the shape memory polymer 1021 may be made of polyurethane (PU) or epoxy resin-based shape memory polymer.

[0043] Specifically, the temperature-slow-release core 103 further includes a dust-free paper 1033 disposed on the outside of the super absorbent resin layer 1032 , and a fluff pulp layer 1031 disposed on the inside of the super absorbent resin layer 1032 .

[0044] The layered design of the temperature-slow-release core 103 allows for slow release of cooling from the inside out, maintaining a constant temperature range of 10-15°C and preventing sudden temperature drops.

[0045] The fluff pulp layer 1031 acts as a liquid-absorbing base layer, quickly absorbing and dispersing the refrigerant to ensure that the cold is stably transferred to the skin contact surface. The dust-free paper 1033 acts as an isolation layer to prevent the leakage of particles from the super absorbent resin layer 1032 and the fluff pulp layer 1031 in the middle layer, while assisting in the uniform release of cold from the inside to the outside to achieve gradient control.

[0046] As can be seen from the above, dynamic fit and comfort: the elastic memory layer 102, through the mesh deformation of the shape memory polymer 1021 and the strip support of the memory alloy wire 1022, allows the ice pack to bend adaptively with head and neck movements (such as turning or lowering the head), avoiding the stiffness of traditional ice packs;

[0047] Long-lasting cold release: The temperature-slow-release core 103 uses SAP to absorb the phase-change material ethanol-ammonium chloride solution, and combined with the layered structure, it extends the cold compress time to 4-6 hours, significantly better than the 1-2 hours of traditional ice packs.

[0048] Skin protection mechanism: The microporous structure of the temperature buffer layer 104 disperses local pressure, and the outer layer of hot air non-woven fabric 101 quickly removes moisture, synergistically reducing the risk of frostbite.

[0049] As attached Figure 2 As shown:

[0050] Example 2: 10 human head and shoulder bionic models were divided into two groups, and used traditional ice packs and the product of Example 1 respectively. The effects are shown in the following table:

[0051]

[0052] Results: This application achieves long-term cooling through the SAP-PCM composite core; the breathable and moisture-wicking structure reduces the risk of frostbite; and the dynamic fitting technology improves patient comfort.

[0053] It is suitable for relieving postoperative swelling of the head, face, and neck, and physical cooling of fever; cold compresses for sports injuries (such as cervical sprains), and cooling of workers working in high temperatures; emergency care for children with fever, and migraine relief; it is especially suitable for sensitive people and scenarios where long-term cold compresses are needed.
