Description

Intramuscular effect patch Technical Field The utility model relates to the technical field of medical auxiliary products, in particular to an intramuscular effect patch. Background After the intramuscular patch is stuck on the skin, blood and lymph fluid under the skin can be unblocked under reasonable movement, pain can be relieved, muscular tension can be regulated, the nervous system can be effectively stimulated, and the effects of relieving or curing muscle, joint inflammation and nervous system diseases can be achieved. The product adopts physical therapy, has no toxic or side effect, and has better effects on body building and rehabilitation training. The functional principle is like a human hand, and the micro massage effect is generated by continuously stretching and massaging the attached part. The intramuscular patch product has better protection and rehabilitation effects on the body of athletes in the field of sports, and has also shown great advantages in the prevention and treatment of some chronic joint diseases, such as knee joints, lumbar joints and other chronic joints in the medical field. The supporting base material of the existing intramuscular effect patch product adopts waterproof elastic cloth, the glue is medical acrylic pressure-sensitive adhesive, and the glue surface is corrugated and incompletely covered on the cloth base. The thickness and air permeability of the intramuscular patch are similar to those of human skin, and the intramuscular patch has continuous natural elasticity when no tension is applied or within the tension range, and can provide continuous beneficial sensory input under limb movement. The existing intramuscular patch can strengthen nerve perception in the use process, and the perception of the adhered part is more obvious under the condition that the ambient temperature suddenly becomes cold, so that the discomfort of a user can influence the application of the product in winter. The intramuscular plaster with the self-heating traditional Chinese medicine can not give consideration to the problems of large temperature difference in four seasons and the like, and can not solve the problem of application comfort of users. Therefore, there is a need to develop an intramuscular patch. Disclosure of utility model The present utility model aims to solve at least one of the technical problems in the related art to some extent. Therefore, the utility model provides the intramuscular patch which can keep the temperature of the application part stable. To this end, a first aspect of the present utility model provides an intramuscular patch comprising: A groove structure is arranged on one side of the support body; pressure sensitive adhesive disposed in the groove structure; a phase change heat storage material dispersed in the pressure sensitive adhesive; Is arranged at the distance from the pressure sensitive adhesive an isolating layer at one side of the supporting body. The utility model fuses the heat storage microcapsule with good safety into the intramuscular effect patch, stores heat into the phase change material when the human body heats or the environmental temperature is high, slowly releases heat when the environmental temperature suddenly becomes low, keeps the temperature of the adhered part stable, and has the functions of reducing the body temperature at high temperature and keeping the body temperature at low temperature. The utility model has simple implementation mode, the product has unobvious feeling when the temperature is changed, the comfort of the human body is enhanced, and the effect is obvious especially when the heat preservation is needed for the rehabilitation treatment of the chronic diseases, and the utility model can prevent the discomfort of the body caused by unsmooth blood due to low temperature.
