Referring to fig. 1, a wrist band provided in this embodiment is used in the medical field, and includes: a heat sensitive layer 10 and a thermal insulation layer 20. Typically the wristband is provided in the form of a strip and is intended to be worn around the wrist or ankle of a patient. The patient's identity information is recorded with the wristband. The heat sensitive layer 10 is disposed on one surface of the heat insulating layer 20. The thermosensitive layer 10 comprises a thermochromic layer which undergoes a colour change when exposed to heat, and this colour change is irreversible. The thermosensitive color-changing layer has a printing surface for recording information; by this color change, writing can be left on the printed surface for recording the identity information of the patient. Specifically, a form of printing the two-dimensional code can be adopted, and the two-dimensional code can occupy a smaller area, so that more contents can be recorded.

The heat insulation layer 20 is arranged opposite to the printing surface of the heat sensitive layer 10, and the thickness of the heat insulation layer 20 is larger than that of the heat sensitive layer 10. When the corresponding wrist band is produced and processed, high-temperature heating is needed. For example, the heat-sensitive layer 10 is printed on the surface of the heat-insulating layer 20, and needs to be dried at a high temperature, in this case, an ultraviolet lamp is used for drying. The uv lamp generates heat which is transferred to the surface of the thermosensitive layer 10 to dry it. In this process, the heat is prevented from penetrating into the interior of the insulating layer 20 by the insulating layer 20, and the insulating layer 20 is prevented from being deformed. The thermal insulation layer 20 also insulates excessive heat from being transferred to the thermosensitive layer 10, and prevents the thermosensitive layer 10 from being blackened.

In the technical scheme provided by the embodiment, the heat-sensitive layer 10 is arranged on the heat-insulating layer 20, and the heat permeation inside the wrist strap is reduced through the heat-insulating layer 20, so that the wrist strap is prevented from being deformed or even broken in the processing process. Increase the thickness of insulating layer 20 simultaneously, insulating layer 20's thickness is thicker like this, and insulating layer 20 is when receiving the heat heating, and non-deformable more further avoids the wrist strap fracture.

In the above embodiment, the thickness of the thermosensitive layer 10 is 70um to 90um, and the thickness of the thermal insulation layer 20 is 100um to 300 um. Specifically, the thermosensitive layer 10, which may also be referred to as a thermosensitive paper, is formed by disposing a thermosensitive color-changing layer on a composite paper. The thickness of heat-sensitive layer 10 can guarantee at 70um ~ 90um when printing the typeface that the typeface can clearly appear. The thickness of the thermal insulation layer 20 is set to be 100-300 um, so that the thermal insulation layer 20 has certain hardness and is used for supporting the thermal sensitive layer 10, and the phenomenon that the wrist strap is too thin and too soft, so that the thermal sensitive color changing layer cannot be smoothly printed on the composite paper is avoided.

In the above embodiment, the insulating layer 20 comprises a stretch resistant material. Generally, the wrist strap is worn on the body of a patient, and the patient inevitably scratches and touches the wrist strap in the process of contacting with the external environment. The anti-stretching material is an existing material, and the wrist strap is prevented from being easily broken in the using process through the anti-stretching performance of the existing material. The stretch resistant material may include a film plastic with good stretch resistance, such as PE (Polyethylene), PET (Polyethylene terephthalate), POE (Polyolefin elastomer), and the like.

In the above embodiment, the thermal insulation layer 20 is provided with the flexible layer 30 on the side facing away from the thermosensitive layer 10, and the flexible layer 30 comprises a flexible material. When a patient wears the wrist strap, the wrist strap is usually in direct contact with the skin. In the related art, the wrist strap facing the skin of the patient is hard, so that the wrist strap is uncomfortable and not soft enough for the patient to wear, and even the edge of the wrist strap scratches the skin of the human body sometimes because the wrist strap is too hard. In this embodiment, the flexible layer 30 is more flexible on the side facing the patient's skin. That is, the flexible layer 30 is made of a flexible material, wherein the flexible material includes EVA (Ethylene-vinyl acetate copolymer), TPU (Thermoplastic polyurethanes, Thermoplastic polyurethane elastomer rubber), PE (polyethylene), POE (Polyolefin elastomer), and the like. These materials are soft and comfortable and do not scratch the contacter. Meanwhile, the materials are close to the skin, light and dry, and the phenomenon that the wrist strap is stuck to the skin can be avoided.

In the above embodiment, the flexible layer 30 and the thermal insulation layer 20 are made of the same material, and the flexible layer 30 and the thermal insulation layer 20 are integrally formed; so the wrist strap is convenient to produce and process. For example, both the thermal insulation layer 20 and the flexible layer 30 are PE or POE materials.

In another embodiment, the flexible layer 30 and the thermal insulating layer 20 are different materials. So, set up to two kinds of materials, guarantee again that the wrist strap can not be heated under the cracked condition, can also avoid the wrist strap to cut skin. For example, the thermal insulating layer 20 is a PET material, and the flexible layer 30 is an EVA or TPU material. The two-layer structure respectively ensures the characteristics of the functional materials of the two-layer structure and is convenient to respectively play a role.

In the above embodiment, the adhesive layer 40 is provided between the thermosensitive layer 10 and the heat insulating layer 20. The adhesive layer 40 is used to adhere the thermosensitive layer 10 and the heat insulating layer 20 together. The thermal sensitive layer 10 and the thermal insulation layer 20 are prevented from being uncovered at will when wearing or printing the recorded patient information, and the wrist strap is prevented from being damaged.

In the above embodiment, the adhesive layer 40 includes a pressure sensitive adhesive having a thickness of 20um to 70 um. The pressure-sensitive adhesive is also called pressure-sensitive adhesive, is called pressure-sensitive adhesive and is also called self-adhesive. The pressure-sensitive adhesive has good adhesion, and can effectively adhere the thermosensitive layer 10 and the heat-insulating layer 20 together. If the thickness of the pressure-sensitive adhesive is less than 20um, the adhesive property is poor, and the adhesive effect is difficult to achieve. And if the thickness of pressure sensitive adhesive is greater than 70um, the thickness of pressure sensitive adhesive itself is too late, the whole thickness of wrist strap is changed, and the patient is uncomfortable to wear, and the cost of wrist strap is increased. Therefore, the thickness of the pressure-sensitive adhesive is 20um to 70um, so that the heat-sensitive layer 10 and the heat-insulating layer 20 can be well adhered together, and the cost can be reduced.

In the above embodiment, the wristband further includes a heat-sensitive protective layer 50, and the heat-sensitive protective layer 50 is disposed on a side of the heat-sensitive layer 10 facing away from the heat-insulating layer 20. The thermosensitive protection layer 50 prevents the thermosensitive layer 10 from being scratched and torn, and also prevents the thermosensitive protection layer 50 from falling off.

In the above embodiment, the wristband further includes a waterproof layer 60, and the waterproof layer 60 is disposed on a side of the heat-sensitive protective layer 50 away from the heat-sensitive layer 10. In actual use of the wristband, the use environment may be complicated, for example, when it is exposed to rain, and a waterproof layer 60 is further provided on the thermosensitive protective layer 50. The heat sensitive layer 10 is prevented from being wetted by the waterproof layer 60, thereby protecting the information recorded on the wristband. In addition, the thermosensitive protection layer 50 and the waterproof layer 60 may be the same transparent material.

In the above embodiment, the heat-sensitive layer 10 and the heat insulating layer 20 have the same area, and the heat-sensitive layer 10 and the heat insulating layer 20 are disposed to overlap. The overlapping arrangement can be understood as that the thermosensitive layer 10 and the heat-insulating layer 20 are arranged in a layered manner and are finally attached together, so that the processing and the production are convenient, and meanwhile, the areas of the thermosensitive layer 10 and the heat-insulating layer 20 are the same, so that the wrist strap looks more tidy and concise.

The above is only the preferred embodiment of the present invention, not so limiting the patent scope of the present invention, all of which are in the utility model discloses a conceive, utilize the equivalent structure transform that the content of the specification and the attached drawings did, or directly/indirectly use all to include in other relevant technical fields the patent protection scope of the present invention.
