Description

Technical Field

[0001] The present invention relates to the technical field of protective equipment for radiotherapy departments, and in particular to a neck protection device for radiotherapy departments. Background Art

[0002] Radiotherapy is the treatment of malignant tumors and some benign diseases using one or more types of ionizing radiation. The means of radiotherapy is ionizing radiation. The most commonly used direct ionizing particles in radiotherapy are electrons, and the most commonly used indirect ionizing particles are photons. The energy range of X-radiation used in radiotherapy is 1-25MV.

[0003] During radiotherapy, patients need to maintain a fixed posture to ensure that the radiation acts accurately on the lesion area while avoiding radiation damage to surrounding healthy tissues. The neck protection device used in radiotherapy is used to ensure that the patient's neck remains in a specific position to reduce errors caused by patient movement.

[0004] However, the existing neck protection devices are usually constrained by rigid materials. Although they can provide a certain stability, during long-term radiotherapy, the contact between the rigid material and the patient's neck can easily cause discomfort to the patient, thereby affecting the effect of the treatment. Correspondingly, when the rigid material fixes the patient's neck, it is easy to produce a local sense of compression, causing the patient to have neck pain and other problems, which is not convenient for long-term use. In addition, the rigid material is universal, so it is not easy to meet the needs of different patients. Therefore, the present invention proposes a neck protection device for radiotherapy to solve the problems existing in the prior art. Summary of the invention

[0005] In view of the above problems, the purpose of the present invention is to provide a neck protection device for radiotherapy department, which has the advantages of good adaptability, sufficient support and high softness to alleviate the discomfort of the patient's neck and can solve the problems existing in the prior art.

[0022] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples. The examples are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0023] During radiotherapy, radiation needs to be precisely focused on the tumor area to ensure that tumor cells receive the maximum dose of radiation while minimizing damage to surrounding healthy tissues. The neck is an easily movable part, and any movement or position change will cause the radiation to deviate from the target area, which will reduce the treatment effect and fail to effectively kill tumor cells. At the same time, incorrect irradiation may damage important surrounding tissues and organs (such as the thyroid gland, esophagus, nerves, etc.). Therefore, by fixing the position of the neck, it can be ensured that the path and target of the radiation are exactly the same during each radiotherapy.

[0024] However, the existing neck protection device is usually restrained by rigid materials. Although the rigid materials have good stability and protection, they are in rigid contact with the patient's neck skin, which can easily cause physical discomfort to the patient and affect subsequent treatment.

[0025] Therefore, according to Figure 1-Figure 6 As shown, this embodiment proposes a neck protection device for radiotherapy, which integrates the support limits of the head and neck, so that the patient can find a more suitable protection pressure during radiotherapy, thereby reducing the discomfort of the patient's neck.

[0026] Specifically, it includes a base plate 1, which serves as the basic structure supporting the entire device and is used to be fixed to the radiotherapy equipment. A headrest is installed above the base plate 1, and a neckrest is installed on the headrest. The headrest is used to support the patient's head and maintain the accurate position of the head and neck during radiotherapy, while the neckrest provides support and protection for the patient's neck and fixes the neck position.

[0027] Furthermore, the neck pillow portion includes an arc-shaped outer base shell 2, the lower end of which is connected to the outer memory foam layer 6 through a silicone pad, which serves as an external support structure to provide the necessary strength and shape stability to adapt to the arc curve of the human neck. A protective airbag belt 3 is installed on the inner side of the arc-shaped outer base shell 2, and an inflation nozzle 4 is provided on the protective airbag belt 3. The two ends of the protective airbag belt 3 are connected by Velcro, and a skin-friendly layer 5 is provided on the inner side of the protective airbag belt 3. At the same time, the length of the protective airbag belt 3 is greater than the length of the arc-shaped outer base shell 2. In this device, airbag support is used to replace the traditional firmware support. The inflated protective airbag belt 3 provides flexible protection, fits the patient's neck, disperses pressure, improves comfort, and reduces the contact pressure between the neck skin and the hard material. Correspondingly, due to the inflatable design, the support strength can be adjusted according to the patient's needs to adapt to different neck shapes. Therefore, this device can adapt to the different needs of most patients and has good pertinence. The protective airbag belt 3 not only plays a supporting role, but also provides a certain buffering function to prevent accidental movement from causing damage to the neck. Correspondingly, the skin-friendly layer 5 directly contacts the patient's skin, providing a soft touch and reducing friction and discomfort.

[0028] The headrest part includes an outer memory foam layer 6, and a water pillow component is arranged inside the outer memory foam layer 6. Specifically, the water pillow component includes an impermeable inner shell 7, and a protective outer shell 8 is arranged outside the impermeable inner shell 7, and both the impermeable inner shell 7 and the protective outer shell 8 are thin films, and a silicone partition 9 is installed inside the impermeable inner shell 7, and the silicone partition 9 is provided in several groups. The impermeable inner shell 7 mainly plays the role of waterproofing and sealing, preventing the internal water medium from leaking to the outside, and adopts medical-grade polymer materials (such as TPU, PVC or composite film), which has good sealing, flexibility and durability, and the protective outer shell 8 provides external protection for the water pillow to prevent the impermeable inner shell from being damaged by external sharp objects or friction, and the material is also flexible. Furthermore, the silicone partition 9 can deform appropriately with the shape of the neck to further fit the patient's body shape. At the same time, the silicone partition 9 effectively limits the free flow of water in the water pillow, reduces the shaking feeling when the patient moves, and improves the stability of neck fixation. Accordingly, the setting of multiple groups of silicone partitions 9 can make the pressure distribution uniform, reduce local pressure concentration, and is suitable for long-term radiotherapy.

[0029] Then, a through hole 14 is provided on the silicone partition 9, and the through hole 14 is provided in several groups. The through hole 14 is used to limit the flow rate of water. A cross partition 15 is provided between two groups of silicone partitions 9, and the cross partition 15 is provided in several groups. A water through hole is provided on the cross partition 15, and the material of the cross partition 15 is consistent with that of the silicone partition 9, and the function of the cross partition 15 is consistent with that of the silicone partition 9.

[0030] The bottom plate 1 is provided with a connection groove 10, and the connection groove 10 is evenly arranged in a plurality of groups. The lower end of the outer memory foam layer 6 extends into the connection groove 10 and is connected to the bottom plate 1 by Velcro. In this embodiment, the connection groove 10 is evenly arranged in five groups. With the Velcro connection, the bottom plate 1 and the outer memory foam layer 6 can be easily separated, so as to facilitate the subsequent cleaning and maintenance of the device.

[0031] An elastic filling layer 11 is provided between the arc-shaped outer base shell 2 and the protective airbag belt 3. The elastic filling layer 11 adheres to the inner side of the arc-shaped outer base shell 2 and extends to the outer side of the arc-shaped outer base shell 2. The distribution of the elastic filling layer 11 is as follows: Figure 2 As shown, it can buffer the pressure between the neck and the device during radiotherapy, while absorbing the slight vibration of the neck. The elastic properties of the elastic filling layer 11 enable it to naturally fit the shape of the neck, and provide additional support when the protective airbag belt 3 is insufficiently inflated, thereby maintaining the support strength of the neck. Furthermore, when the protective airbag belt 3 fails, the elastic filling layer 11 can play a protective isolation role between the neck and the arc-shaped outer base shell 2 to reduce the patient's discomfort. In this device, the arc-shaped outer base shell 2 has a certain elasticity, which can be bent by the staff with both hands to expand the spacing of the upper opening of the arc-shaped outer base shell 2. After the patient's neck enters, the staff can release it.

[0032] Two groups of water nozzles 12 are installed on the outer memory foam layer 6, and the two groups of water nozzles 12 are connected to the impermeable inner shell 7. Circulating water pipes 13 are installed on the water nozzles 12, and the two groups of circulating water pipes 13 are respectively connected to the output end and the input end of the external circulating water equipment. A water pipe guide 16 is installed on the bottom plate 1, and two groups of water pipe guides 16 are symmetrically arranged. The lower end of the water pipe guide 16 is provided with a bayonet, and one end of the water pipe guide 16 is installed with a silicone ring 17 through a spring. The function of the water pipe guide 16 is to allow the circulating water pipe 13 to pass through and to limit it, so as to play a protective role.

[0033] The corresponding external circulating water equipment includes a circulating water pump and a circulating water tank. A heater is provided on the inner side of the circulating water tank. The output end of the circulating water tank is connected to the input end of the circulating water pump through a pipeline. The output end of the circulating water pump is connected to a group of circulating water pipes 13, and another group of circulating water pipes 13 is connected to the input end of the circulating water tank. When the device is working, the water in the water pillow assembly can circulate. Therefore, the device can adjust the support force required by the patient by filling water. At the same time, it can also use circulating water to transport heated water (water temperature 37±1℃) into the water pillow assembly. The overall heating and circulation devices are all set outside to reduce the risk of electromagnetic interference. The warm water pillow helps to relax the neck muscles through heat transfer and reduce discomfort and tension during treatment.
