[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] See also Figure 1-Figure 4 The utility model provides a technical solution: a hydrogel patch with temperature color strips, comprising a bottom lining layer 1, a hydrogel patch layer 10 is arranged on the surface of the bottom lining layer 1, a longitudinal color strip 11 is arranged on the hydrogel patch layer 10, and a transverse color strip 12 is also arranged on the hydrogel patch layer 10, the longitudinal color strip 11 and the transverse color strip 12 are perpendicular to each other, so that after the hydrogel patch layer 10 is attached to the skin, as long as one of the longitudinal color strip 11 or the transverse color strip 12 is in contact with the skin part to realize the color development operation, it is ensured that in some occasions, when the hydrogel patch layer 10 cannot be completely attached to the skin for use, one of the longitudinal color strip 11 or the transverse color strip 12 can be attached to the skin part for use;
[0026] The longitudinal color strip 11 and the transverse color strip 12 are both located at a position away from the symmetry axis of the base layer 1. The transverse color strip 12 and the longitudinal color strip 11 are mixed with the hydrogel on the hydrogel application layer 10. The hydrogel is a transparent material, and the transverse color strip 12 and the longitudinal color strip 11 can be made of a thermosensitive material that can change color according to changes in temperature. The base layer 1 is also made of a transparent film material, so that the color of the transverse color strip 12 and the longitudinal color strip 11 can be observed from the back to judge the approximate temperature of the hydrogel application layer 10.
[0027] In this embodiment, a side adhesive layer 13 is provided on the upper surface of the base lining layer 1 near the side position, and the cross-section of the side adhesive layer 13 is a rectangular ring. The hydrogel application layer 10 is located at the center of the side adhesive layer 13, which is convenient for adhering to the skin by using the side adhesive layer 13 to achieve a fixing effect, so that the base lining layer 1 is not easy to fall off the skin.
[0028] Specifically, a first anti-sticking protrusion 131 is provided on the surface of the side adhesive layer 13. The first anti-sticking protrusion 131 is used to reduce the sticky area of the side adhesive layer 13, so that the contact area between the side adhesive layer 13 and the skin is relatively reduced. Under the contact action of the first anti-sticking protrusion 131, the side adhesive layer 13 can be relatively easily torn off from the skin, thereby preventing the side adhesive layer 13 from adhering too tightly to the skin and affecting the normal tearing operation.
[0029] Furthermore, a release film 2 is provided on the surface of the hydrogel application layer 10 and the side adhesive layer 13, and the release film 2 is used for protection operation.
[0030] In addition, end tear-off stickers 20 are provided at both ends of the release film 2. The end tear-off stickers 20 and the release film 2 are an integrally formed structure, ensuring that the structure of the end tear-off stickers 20 and the release film 2 is more firm and stable; the cross-section of the end tear-off stickers 20 is arc-shaped, and the side parts of the end tear-off stickers 20 are upwardly curled for tearing operation.
[0031] It is worth noting that a back pulling belt 21 is fixedly installed between the side portions of the two end tear-off stickers 20, and the back pulling belt 21 is used for pulling and tearing operations, so that the end tear-off stickers 20 and the release film 2 can be torn off from the hydrogel application layer 10 more smoothly by pulling the back pulling belt 21.
[0032] It is worth noting that a plurality of second anti-adhesion protrusions 22 arranged at equal intervals are provided on the inner side surface of the release film 2. The second anti-adhesion protrusions 22 are used to reduce the adhesion area, so that the separation operation between the release film 2 and the hydrogel application layer 10 is smoother.
[0033] In this embodiment, the width of the side adhesive layer 13 is 0.3cm~0.5cm, so that the side adhesive layer 13 can be properly adhered and fixed to the skin part, and the width of the longitudinal color display strip 11 and the transverse color display strip 12 is 0.6cm~1.2cm, so that the longitudinal color display strip 11 and the transverse color display strip 12 can better perform display operations.
[0034] When using the hydrogel patch with temperature color strips of the utility model, the release film 2 is torn off, and then the hydrogel patch layer 10 is aligned with the patch part, and then the hydrogel patch layer 10 is attached to the patch part, and finally the side adhesive layer 13 is properly adhered and fixed on the skin to complete the fixing operation. Subsequently, the approximate temperature of the hydrogel patch layer 10 can be judged by observing the color changes of the horizontal color strips 12 and the vertical color strips 11.
[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
