Description
Technical Field
The utility model relates to the technical field of medical equipment, concretely relates to a scalp cooling system for preventing cancer chemotherapy is lost hair.
Background
Antineoplastic drugs are mainly used to destroy the highly proliferative active keratinocytes in the growth phase and their pigment systems. The influence on the mitosis phase of the hair follicle is large, and the hair follicle is easy to undergo apoptosis mainly due to the fact that the hair follicle is very sensitive to toxins or drugs. In addition, the hair accounts for a higher proportion (about 90 percent) in scalp hair follicles, and is more easily influenced by the anti-tumor drugs. Chemotherapy alopecia occurs in association with the type of drug: the chemical medicine most likely to cause alopecia is adriamycin, vincristine, cyclophosphamide, etc. The incidence rate of the hair loss of the microtubule inhibitor is over 80 percent, the incidence rate of the topoisomerase inhibitor is 60 to 100 percent, the incidence rate of the alkylating agent is over 60 percent, and the incidence rate of the antimetabolite is 10 to 50 percent, wherein the incidence rate of the hair loss of the multi-drug chemotherapy is higher than that of the single-drug chemotherapy. The chemotherapy-induced alopecia is reversible, and the hair of a user is reproducible after the chemotherapy is finished for 3-6 months; permanent alopecia is rare and is often related to the damage of hair follicle stem cells by high-dose chemotherapy drugs and long-term chemotherapy.
International patent application No. WO98/16176 (Olofsson), published in 1998, discusses in detail the problem of hair loss experienced by users undergoing chemotherapy. According to this document, cooling the skin (and here the hair roots) to a temperature in the range of 0 ℃ to +5 ℃ reduces the capacity of the roots to absorb the therapeutic agent and thus increases the chances of the roots undergoing treatment, thus causing the user to retain his hair. According to WO98/16176, the cooling treatment will preferably last for 1 to 5 hours.
One known head covering in the form of a soft cap composed of a block of soft cryogel is placed over the head of a user. When the soft cap is placed on the user's head, the block is heavy and often has a temperature below-18 ℃. The device is uncomfortable because the bonnet is inflexible and initially very cold. Another problem is that the frozen mass melts rapidly and therefore does not keep the temperature below the upper temperature limit during the entire treatment period. When the temperature rises from-18 ℃ to above +10 ℃, the user must replace the soft cap, typically at about 45 minutes after the head covering is applied.
The Chinese patent with publication number CN107854211A also discloses a medical ice cap, which comprises an ice cap body, a connecting channel and a refrigeration host, wherein the ice cap body consists of a cushion bottom layer, a capillary network cooling layer and an external heat insulation layer, the capillary network cooling layer is fixed on the cushion bottom layer, the capillary network cooling layer is provided with a plurality of mutually independent refrigerant circulating pipelines, and the liquid inlet ends and the liquid outlet ends of the mutually independent refrigerant circulating pipelines are respectively connected with the refrigeration host through a liquid inlet channel and a liquid outlet channel of the connecting channel by a liquid distributor and a liquid collector.
