Description

Portable intelligent temperature control low body temperature first-aid rewarming cap

Technical Field

The utility model relates to the technical field of medical first-aid equipment, in particular to a portable intelligent temperature-control low-body-temperature first-aid rewarming cap.

Background

When working under extremely low-temperature environments such as military operations, polar investigation, mountain climbing and the like, personnel are extremely vulnerable to low-temperature threat, and hypothermia becomes a serious risk of life threatening. Hypothermia can seriously affect physiological functions of a human body, such as metabolism slowing, nervous system dysfunction, burden increase of cardiovascular systems and the like, and even cause cardiac arrest, thus directly threatening life safety.

In the field of outdoor hypothermia treatment, heat dissipation reduction and rewarming are two main key points. Among them, protection against heat dissipation is particularly important, especially for the protection of the head and face. The human body is effectively protected in a low-temperature environment by covering most parts of the body with clothes, but the head and the face are often exposed. Related researches show that under the low-temperature environment, the heat emitted by a human body through the head and the face can reach 30% of the total heat emission of the human body, so that the head and the face can be effectively protected outdoors under the low-temperature condition, the heat loss of the human body can be greatly reduced, and favorable conditions are created for subsequent re-warming and curing.

The rewarming is used as a key link for curing hypothermia and is mainly divided into passive rewarming and active rewarming. The passive rewarming is realized by the heat generated by the wounded and by the warming measures such as blanket covering and the like, and is only suitable for light hypothermia wounded. For severe hypothermia wounded, active rewarming is more necessary. Active rewarming is further subdivided into superficial rewarming and intra-superficial rewarming. In an outdoor environment, the in-vivo rewarming methods such as respiratory tract rewarming, hemodialysis, peritoneal dialysis and the like have extremely high requirements on equipment and operation, and require special sites and professionals to implement. The body surface rewarming becomes an outdoor main rewarming mode, and the body surface temperature is raised by using heat sources such as hot water bath, electric blanket, radiant heat and the like, but the simple body surface rewarming has the problems of lower efficiency and weaker effect, and the body temperature postfalling effect is easy to be caused, so that the deep body temperature of a wounded is continuously reduced, and a great risk is brought.

The carotid artery of the neck is critical to the blood circulation of the human body, is the artery with the largest blood flow in the body surface artery, and the blood flow of the carotid artery accounts for 10% -15% of the heart blood transfusion amount. Through heating carotid artery, can carry the heat to whole body with the help of blood circulation is quick, effectively promotes core body temperature. The carotid artery heating can be applied to the body surface, but can realize the in-vivo rewarming effect, and has the characteristic of high-efficiency rewarming. In addition, the human forebreast area plays an important role in rapidly increasing the core body temperature, especially in the areas where important organs such as heart and lung are located. The heat conduction efficiency of cardiopulmonary is higher, through the body surface heating of chest, can promote the temperature of cardiopulmonary fast, and then through blood circulation with heat transfer to whole body to realize the effect of quick intensification.

However, there are a number of disadvantages to the hypothermia treatment equipment currently on the market. In terms of reducing heat dissipation, most products are deficient in terms of head-to-face protection heat dissipation. On the one hand, these devices mostly meet the need for heating the body or whole body, resulting in a larger volume, or a heavier weight, in terms of rewarming function. On the other hand, the existing outdoor hypothermia treatment equipment adopts a body surface rewarming mode and cannot quickly and efficiently rewarming as in-vivo, so that the rewarming effect of the existing treatment equipment is relatively poor and the efficiency is low, and when the severe hypothermia wounded is treated in emergency, the rewarming equipment cannot meet the strict requirement on timeliness in gold treatment time.

For the above reasons, there is an urgent need to provide a low-body-temperature first-aid rewarming device for precisely heating key parts of a human body, and rapidly raising core body temperature by using blood circulation.
