Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical cosmetology, in particular to a self-adaptive deformation cold compress bag and a preparation process. BACKGROUND

[0002] Medical cold compress is a physical therapy widely used in clinical treatment and daily nursing. It directly acts on the local skin surface of the human body by using low-temperature materials such as ice bags, cold compresses or cold gels, etc., to achieve the purpose of reducing the temperature of local tissues, shrinking blood vessels, reducing inflammation and relieving pain. Medical cold compress is not only suitable for the initial treatment of acute sprains, contusions, muscle strains and other sports injuries, but also plays an important role in postoperative recovery, chronic pain management and the adjuvant therapy of certain inflammatory diseases.

[0003] Ordinary cold compress devices often cannot closely adhere to the complex contours of the skin surface, such as joints, neck and other irregular parts, resulting in a significant reduction in cold compress effect. This poor adhesion not only makes the cold compress uneven, but also may weaken the therapeutic effect. At the same time, existing cold compress devices are usually equipped with fixed straps, but the straps are easy to be contaminated with dirt, sweat and skin residues during repeated use, and if they cannot be detached, they are difficult to clean and disinfect thoroughly. This not only shortens the service life of the straps, but also may cause skin infection or allergy and other problems. However, the traditional straps are mostly fixed on both sides of the device by sewing and other technologies, which are inconvenient to detach and maintain, bringing many inconveniences to users.

[0014] A self-adapting deformation cold compress bag and a preparation process, the specific processing steps are as follows: S1. Select lightweight plastic as the material of the main body, and open an oval groove in the lower surface, while reserving a slot on both sides. Fix the heat-conducting sheet in the oval groove to ensure that it is tightly attached to the groove wall, so as to achieve high-efficiency heat dissipation. Then, according to the size and shape of the main body, cut the sponge layer to perfectly fit the lower surface of the main body, and evenly open multiple mounting slots on the side surface of the sponge layer. Place the graphene guide sheet in these mounting slots to ensure that it is tightly attached to the sponge layer, so as to optimize the heat dissipation performance. Finally, firmly fix the skin-friendly layer on the outer arc surface of the sponge layer by pressing or bonding, etc. process, so that the skin-friendly layer is combined with the sponge layer, providing a soft and comfortable contact experience for the user.

[0015] S2. First, a light plastic is selected to make the mounting seat, which is formed into a I-shaped and hollowed by means of a mold or hot pressing technology. Then, the first and second straps are fixed on the side surface of the mounting seat respectively, and the magic tape hair surface is fixed on the upper surface of the second strap, and the magic tape hook surface is fixed on the lower surface of the first strap. Then, a sliding groove is opened on the inner lower surface of the mounting seat, and a notch and a square groove are opened on the side surface and the upper surface respectively. The sliding plate is assembled into the sliding groove, ensuring that it can slide in the groove. Then, the spring and the telescopic rod are fixed to the inner side surface of the sliding groove, and the other end is fixed to the side surface of the sliding plate. Then, the second rotating shaft is installed in the recessed part on both sides of the I-shaped sliding plate, the first rotating shaft is installed on the upper surface of the sliding block, the insertion column is fixed on the side surface of the sliding block, and the movable rod is fixed at both ends of the second rotating shaft and the first rotating shaft, so as to ensure that the movable rod can drive the sliding block to move smoothly.

[0016] S3. Next, the cover is formed by means of a mold or hot pressing technology. The second chain strip is installed on the lower surface of the cover, and the first chain strip is fixed on the upper surface of the main body, and the pull head is assembled at the second chain strip. Then, the cold gel is injected into the ice bag, and the ice bag is edge sealed to ensure that there is no risk of leakage. The ice bag is placed in a refrigerated environment until it is completely frozen. After freezing, the ice bag is placed on the upper surface of the heat conduction sheet, and the ice bag is placed in the main body by means of the close cooperation of the cover, the first chain strip and the second chain strip.

[0017] Working principle: when in use, the frozen ice bag is placed on the upper surface of the heat conduction sheet, and then the pull head is pulled to make the first chain strip and the second chain strip interlock, so that the cover and the main body form a relatively closed space. Then, the device is placed on the skin part to be cooled, and the sponge layer can be adapted to the concave and convex of the skin surface by means of the self-adaptive property. At this time, the cold released by the ice bag is transmitted to the sponge layer through the heat conduction sheet and the graphene guide sheet, so that the skin-friendly layer can be attached to the skin to achieve the cooling effect. Then, the second strap and the first strap are crossed into a ring shape, and the device is fixed on the skin by means of the cooperation of the magic tape hair surface and the magic tape hook surface, so as to prevent the main body from moving. If the mounting seat needs to be disassembled, the sliding plate can be buckled to slide in the sliding groove, the spring is stretched under stress, the sliding plate moves to drive the movable rod to rotate around the first rotating shaft and the second rotating shaft, so that the insertion column is separated from the limiting groove, so that the fixing of the mounting seat is released, and the mounting seat can be taken down for maintenance.

[0018] (Three) beneficial effects The present application provides a self-adaptive deformation cold compress bag and a preparation process. It has the following beneficial effects: 1. The cold released by the ice bag is transmitted to the sponge layer through the heat conduction sheet and the graphene guide sheet, and the sponge layer is adapted to the concave and convex of the skin surface by means of its self-adaptive property, so that the skin-friendly layer is closely attached to the skin, and the cooling effect is improved.

[0019] 2, by pulling the slide plate, make it slide in the chute, the spring is stretched. The slide plate moves to drive the movable rod to rotate around the first and second rotating shafts, prompting the insertion column to disengage from the limiting groove, thereby releasing the fixing of the mounting seat, facilitating the removal of the second strap and the first strap for maintenance.
