DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Tumor radiotherapy, also known as radiotherapy, is a treatment method that uses high-energy rays (such as X-rays, gamma rays) or other particles (such as protons, electrons) to kill cancer cells or prevent their growth. It is one of the important means of treating many types of cancer. It can be used alone or in combination with other treatments such as surgery and chemotherapy. Tumor radiotherapy is an effective cancer treatment method, but it also brings certain side effects, such as fatigue, skin changes, and hair loss. The hair loss caused by tumor radiotherapy is mainly closely related to the size of the radiotherapy irradiation area, the radiation incidence route and the dose. For example, whole-brain radiotherapy will cause more than 75% temporary hair loss, while multi-angle radiation incidence of small intracranial tumors will cause scattered temporary hair loss, and local temporary hair loss in the back of the brain may occur in nasopharyngeal carcinoma radiotherapy;

[0022] There are many ways to reduce hair loss caused by radiotherapy, such as using mild shampoo and conditioner, avoiding hot air hair dryers and tight hair accessories, and wearing hats or scarves to protect the scalp when going out. During radiotherapy, patients can reduce hair loss by wearing hair loss protection headgear. Hair loss protection headgear usually uses scalp cooling technology to reduce the impact of radiotherapy on hair follicles by lowering the scalp temperature. When using it, the patient needs to wear the headgear on the head to ensure that it fits the scalp tightly. The headgear may need to be pre-cooled for a period of time before treatment to achieve the best effect. During radiotherapy, the headgear should be worn continuously to keep the scalp at a low temperature.

[0023] Based on the findings in the prior art, the existing hair loss protection headgear used for tumor radiotherapy mostly has a single function, and it is not convenient to monitor and control the cooling temperature inside the headgear in real time, resulting in discomfort to the patient's scalp when the cooling temperature inside the headgear is too low, thereby reducing the patient's wearing comfort. In addition, the existing hair loss protection headgear used for tumor radiotherapy mostly has a fixed size, which is not convenient for adaptive adjustment according to the different head sizes of different patients, and thus cannot be suitable for different patients to wear stably.

[0024] For the problems existing in the above-mentioned prior art, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5The present embodiment provides a hair loss protective headgear for tumor radiotherapy, comprising an arc-shaped cover body 1 designed to imitate a human head and a connecting ring 2 fixed to the bottom end of the arc-shaped cover body 1, the connecting ring 2 is annular in design and a mask 3 is fixed to its bottom end, a cooling water tank 4 for storing cooling water is fixed at the top center position of the arc-shaped cover body 1, a first micro-water pump 5 is fixed to the bottom end of the cooling water tank 4, a shunt box 6 is fixed to the top center position of the inner top of the arc-shaped cover body 1, the output end of the first micro-water pump 5 penetrates into the arc-shaped cover body 1 and is fixedly connected to the top of the shunt box 6, an annular refrigeration cavity 7 for cooling cooling water is provided inside the connecting ring 2, cooling water pipes 8 are fixed to the outer side wall of the shunt box 6 and are distributed in an annular manner and are located in the side wall of the arc-shaped cover body 1, the bottom end of the cooling water pipe 8 penetrates the connecting ring 2 and is connected to the annular refrigeration cavity 7, semiconductor refrigeration plates 9 are fixed to the left and right side walls of the annular refrigeration cavity 7, and the refrigeration end of the semiconductor refrigeration plate 9 is located in the annular refrigeration cavity 7, The heat dissipation section of the semiconductor refrigeration sheet 9 is located outside the connecting ring 2. A water circulation mechanism is connected between the annular refrigeration cavity 7 and the cooling water tank 4, and the cooling water in the annular refrigeration cavity 7 is re-injected into the cooling water tank 4 through the water circulation mechanism. Temperature sensors 10 are fixed to the lower parts of the inner walls on both sides of the arc-shaped cover body 1. The temperature sensor 10 is connected to the PLC control system of the hair loss protection headgear, and is used to shut down the first micro-water pump 5 when the temperature is detected to be lower than a preset value, and the cooling water in the cooling water tank 4 is pumped into the shunt box 6 and injected into the cooling water pipe 8 through the first micro-water pump 5 to achieve cooling of the patient's scalp. At the same time, the temperature of the inner side of the arc-shaped cover body 1 is monitored in real time through the temperature sensor 10. When the temperature is detected to be lower than the preset value, the first micro-water pump 5 is shut down to stop cooling. When the temperature is detected to be higher than the preset value, the first micro-water pump 5 is started again to continue cooling, thereby achieving real-time monitoring and control of the cooling temperature in the arc-shaped cover body 1;

[0025] A hollow arc-shaped sliding sleeve 11 is symmetrically provided below the connecting ring 2. There are four groups of arc-shaped sliding sleeves 11 and they are symmetrically fixed on the front, back, left and right sides of the upper outer wall of the mask 3. An arc-shaped slide plate 12 is slidably provided between adjacent arc-shaped sliding sleeves 11. There are also four groups of arc-shaped slide plates 12 and they are not fixedly connected to the mask 3. The arc-shaped slide plates 12 and the arc-shaped sliding sleeve 11 are fixedly connected by a positioning mechanism. The arc-shaped sliding sleeve 11 and the arc-shaped slide plate 12 are adaptively slidably adjusted to adapt to the head circumference of different patients, and the arc-shaped sliding sleeve 11 and the arc-shaped slide plate 12 are positioned and fixed by the positioning mechanism, so that the hair loss protection headgear used for tumor radiotherapy can be suitable for different patients to wear stably.

[0027] A water injection pipe 15 for adding cooling water is fixed at the top of the cooling water tank 4. A threaded cap 16 is screwed on the top of the water injection pipe 15. The top of the water injection pipe 15 is sealed by the threaded cap 16. A sealing ring is fixed to the bottom of the threaded cap 16 and the size of the sealing ring is adapted to the water injection pipe 15. When the threaded cap 16 is covered on the water injection pipe 15, the sealing ring seals the connection between the two.

[0028] The outer wall of the arc-shaped cover body 1 is made of a hard material and a support rod 17 is symmetrically fixed on its top. The top of the support rod 17 is fixed to the bottom end of the cooling water tank 4 to support the cooling water tank 4. The cooling water pipe 8 is designed to be arc-shaped and is adapted to the curvature of the arc-shaped cover body 1. The cooling water pipe 8 is evenly distributed in the side wall of the arc-shaped cover body 1 to achieve a better cooling effect.

[0029] The side wall of the arc-shaped cover body 1 is provided with evenly distributed ventilation holes 18, which connect the inside and outside of the arc-shaped cover body 1, making the arc-shaped cover body 1 more breathable and improving the wearing comfort of the patient. The inner wall of the arc-shaped cover body 1 is made of soft material and is fixed with evenly distributed arc-shaped silicone protrusions 19 to improve the comfort of the patient's scalp. The inner wall of the connecting ring 2 is fixed with a forehead sponge buffer ring 20 to avoid direct contact between the connecting ring 2 and the patient's forehead, thereby improving the comfort of the patient's forehead.

[0030] The water circulation mechanism includes a first pumping pipe 21 and a second pumping pipe 22, wherein the first pumping pipe 21 is fixed to the front of the connecting ring 2 and is connected to the annular refrigeration chamber 7, and the second pumping pipe 22 is fixed to the front of the cooling water tank 4 and is connected to the inside of the cooling water tank 4. A second micro water pump 23 is connected between the first pumping pipe 21 and the second pumping pipe 22. The cooling water in the annular refrigeration chamber 7 is re-pumped into the cooling water tank 4 through the first pumping pipe 21 and the second pumping pipe 22 by the second micro water pump 23 to achieve recycling.

[0031] An elastic opening 24 is fixed at the bottom end of the mask 3 to facilitate the patient to wear it. Ear sponge buffer bumps 25 are fixed to the upper part of the inner walls on both sides of the mask 3 to buffer the patient's ears. A vent 26 is opened at the lower part of the rear side wall of the mask 3 and a filter is fixed in the vent 26 to improve the air permeability of the mask 3.

[0032] An observation port 27 is provided on the upper front part of the mask 3, which is located at the patient's eye position. A nasal breathing port 28 is provided on the front part of the mask 3 below the observation port 27 to facilitate the patient's nose breathing. An oral breathing port 29 is provided on the front part of the mask 3 below the nasal breathing port 28 to facilitate the patient's mouth.

[0033] When the hair loss protective headgear for tumor radiotherapy is actually used, the patient first extends the head into the mask 3 through the elastic opening 24, and makes the arc-shaped mask body 1 cover the patient's scalp, and then slides and adjusts the arc-shaped sliding sleeve 11 and the arc-shaped sliding plate 12. The arc-shaped sliding plate 12 is extended into the arc-shaped sliding sleeve 11 to reduce the surrounding size of the upper part of the mask 3, and the arc-shaped sliding plate 12 is slid out of the arc-shaped sliding sleeve 11 to expand the surrounding size of the upper part of the mask 3, until the upper part of the mask 3 just fits the forehead position of the patient's head. At this time, the positioning mechanism is used to position and fix the arc-shaped sliding sleeve 11 and the arc-shaped sliding plate 12, so that the hair loss protective headgear for tumor radiotherapy can be stably worn on the patient's head;

[0034] When the patient's scalp needs to be cooled, cooling water is pre-stored in the cooling water tank 4, and the first micro water pump 5 is started to pump the cooling water in the cooling water tank 4 into the shunt box 6, and then the shunt box 6 injects the cooling water into the cooling water pipe 8 and finally merges into the annular refrigeration cavity 7 in the connecting ring 2. When cooling water passes through the cooling water pipe 8 distributed in an annular shape in the side wall of the arc-shaped cover body 1, the temperature of the arc-shaped cover body 1 is reduced through heat exchange, and the inner wall of the arc-shaped cover body 1 cools the patient's head scalp again, and the effect of radiotherapy on hair follicles is reduced by reducing the scalp temperature, so as to achieve the effect of hair loss protection. The cooling water merged into the annular refrigeration cavity 7 is cooled by the semiconductor refrigeration sheet 9, and after cooling, it is re-injected into the cooling water tank 4 by the water circulation mechanism to achieve recycling;

[0035] When cooling the patient's scalp, the temperature sensor 10 is used to monitor the temperature inside the arc-shaped cover body 1 in real time. When the monitored temperature is lower than the preset value (indicating that the cooling temperature of the patient's scalp is too low, which will cause discomfort to the patient), the first micro water pump 5 is turned off to stop continuing to inject water into the cooling water pipe 8, so that the temperature inside the arc-shaped cover body 1 rises again. When the monitored temperature is higher than the preset value, the first micro water pump 5 is started again to continue to inject water into the cooling water pipe 8, and the patient's scalp is continued to be cooled, thereby realizing real-time monitoring and intelligent control of the cooling temperature.
