Description

Technical Field

[0001] The present invention relates to the field of radiotherapy auxiliary equipment, and in particular to a tumor radiotherapy protection device. Background Art

[0002] In the field of tumor radiotherapy, the neck, as one of the common radiotherapy targets, requires shielding of non-target tissues (such as the thyroid gland and spinal cord) through protective devices, while maintaining the stable position of the patient's head and neck to ensure that the radiotherapy rays are accurately focused on the lesion. With the advancement of radiotherapy technology and the increase in patient comfort requirements, neck protection devices must not only meet the requirements of protection effectiveness, but also take into account the patient's physical experience during long-term treatment, driving the development of protective equipment towards a combination of functionality and comfort.

[0003] Existing neck radiotherapy protection devices are mainly composed of a head support pad, a neck protector body, a shielding layer and a fixing component; the head support pad supports the patient's head, the neck protector body fits the neck curve, the built-in lead plate and other shielding materials block radiation penetration, and the straps and other fixing components limit body movement, forming an integrated structure of "support, protection and fixation"; this type of device relies on ergonomic design to reduce non-target radiation damage during radiotherapy, providing basic protection for radiotherapy of neck tumors.

[0004] In actual applications, existing neck protection devices have a long radiotherapy treatment cycle, with a single treatment usually taking tens of minutes. The patient's head needs to fit closely against the head support pad for a long time. The support pad is mostly made of elastic materials with strong sealing properties and poor air permeability, making it difficult for heat and sweat to dissipate, which can easily lead to stuffiness and humidity in the head contact area. This discomfort can increase the patient's tension during radiotherapy, and even cause irritability and restlessness, affecting body position stability and indirectly reducing the accuracy of radiotherapy. At the same time, long-term stuffy environments may irritate the patient's skin, especially for cancer patients with weak immunity, which can easily increase the risk of skin allergies and infections, making it difficult to balance the protective effect and the patient's treatment comfort needs. Therefore, there is an urgent need to improve the existing tumor radiotherapy protection devices. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a tumor radiotherapy protection device to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tumor radiotherapy protection device, comprising a mounting plate, a head support seat mounted on the mounting plate, and a head protection pad mounted on the head support seat for supporting the patient's head, wherein the outer wall of the head protection pad is provided with a first heat dissipation slot and a second heat dissipation slot for ventilation; The head support seat is equipped with a fan, and an air guide mechanism is provided inside the head support seat. The head protection pad is provided with air guide holes connected to the first heat dissipation slot and the second heat dissipation slot. The air guide holes cooperate with the air guide mechanism and the fan, as well as the first heat dissipation slot and the second heat dissipation slot to dissipate heat for the patient synchronously, thereby improving the patient's comfort. The outer wall of the head support seat is embedded with a guard plate located in the openings of the first heat dissipation slot and the second heat dissipation slot, and the guard plate corresponds to the setting position of the air guide hole and is used to block the airflow discharged from the air guide hole.

[0007] By adopting the above technical solution, the head support seat and the protective pad are coordinated, and the heat dissipation groove, air guide holes, fan and protective plate work together to stably support the head to ensure accurate radiotherapy, and dissipate heat. The protective plate guides air to prevent impact and improve comfort.

[0008] Furthermore, the first heat dissipation grooves and the second heat dissipation grooves are provided in multiple groups on the outer wall of the top of the head protection pad, and the multiple groups of first heat dissipation grooves and the multiple groups of second heat dissipation grooves are staggered and interconnected.

[0009] By adopting the above technical solution, multiple sets of staggered heat dissipation slots are connected to reduce the contact area of ​​the head, leaving channels for airflow, enhancing the heat dissipation effect, alleviating the stuffiness caused by long-term contact, and reducing skin discomfort.

[0010] Furthermore, there are multiple groups of air guide holes at the bottom of the head protection pad, and the diameter of the air guide holes is greater than the width of the first heat dissipation slot and the second heat dissipation slot.

[0011] By adopting the above technical solution, the position of the air guide holes corresponds to the connection of the heat sink, allowing the airflow to enter accurately, improving the heat dissipation efficiency and ensuring the smooth operation of the heat dissipation function.

[0012] Furthermore, the opening positions of the multiple groups of air guide holes all correspond to the positions where the first heat dissipation slots and the multiple groups of second heat dissipation slots are connected, and protective plates are provided above the air guide holes that are connected to the first heat dissipation slots and the multiple groups of second heat dissipation slots.

[0013] By adopting the above technical solution, the airflow can be dispersed to the heat dissipation slots to avoid the discomfort of direct blowing, taking into account both heat dissipation and body sensation.

[0014] Furthermore, the width of the guard plate is greater than the diameter of the air guide hole, and the thickness of the guard plate is less than the depth of the first heat dissipation slot and the plurality of groups of second heat dissipation slots.

[0015] By adopting the above technical solution, the guard plate can effectively guide air while not hindering the ventilation of the heat sink, thus balancing the air guiding function and the normal use of the heat sink.

[0016] Furthermore, the air guide mechanism includes an air guide groove and a diversion groove. The air guide groove is opened in the bottom of the head support seat and corresponds to the position of the fan. In addition, multiple groups of diversion grooves connected to the air guide holes and the air guide grooves are opened in the bottom of the head support seat, and the air guide grooves and the diversion grooves are both larger than the air guide holes.

[0017] By adopting the above technical solution, the air guide groove and the diversion groove cooperate to evenly distribute the fan airflow to the air guide holes.

[0018] Furthermore, an air flow slot corresponding to the fan is provided on the mounting plate, and the width and length of the air flow slot are both greater than the fan.

[0019] By adopting the above technical solution, it is ensured that the fan inhales sufficient air, provides sufficient air source for the air guide mechanism, ensures stable heat dissipation effect, and meets continuous heat dissipation needs.

[0020] In summary, the present invention mainly has the following beneficial effects: The present invention dissipates heat from the patient's head through the first and second heat dissipation slots that are intertwined and connected on the head protection pad, in conjunction with an air guide mechanism, a fan and air guide holes. The head protection pad can not only stably support the patient's head to ensure the accuracy of radiotherapy, but also use the airflow to take away the heat and moisture from the head. At the same time, the guard plate can prevent the airflow from directly impacting the patient, taking into account the body position fixation, heat dissipation effect and comfort of use.

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0025] The following describes an embodiment of the present invention based on its overall structure.

[0026] A tumor radiotherapy protection device, such as Figure 1 - Figure 5 As shown, it includes a mechanism body, which includes a mounting plate 1, a head support seat 2 and a head protection pad 3; The mounting plate 1 is used to fix the device to the radiotherapy equipment and provide stable support; the head support seat 2 is installed on the mounting plate 1. At the same time, the head protection pad 3 is installed on the head support seat 2 to support the patient's head. It adopts an ergonomic design that adapts to the curve of the head. It can not only fix the patient's head position to ensure the accuracy of radiotherapy, but also reduce the patient's sense of pressure through the soft material. In some examples, a lifting mechanism may be installed on the mounting plate 1 to adjust the height of the head support seat 2 .

[0027] Specifically, the outer wall of the head protection pad 3 in this embodiment is provided with a first heat dissipation groove 4 and a second heat dissipation groove 5, both of which are used for ventilation and heat dissipation; a fan 6 is installed on the head support seat 2, and the head support seat 2 is provided with an air guide mechanism, and an air guide hole 9 is provided on the head protection pad 3, which is connected to the first heat dissipation groove 4 and the second heat dissipation groove 5, and cooperates with the air guide mechanism and the fan 6 to simultaneously dissipate heat for the patient's head, thereby improving the patient's comfort during long-term radiotherapy.

[0028] It should be noted that in this embodiment, a protective plate 10 is embedded in the outer wall of the head support seat 2. The protective plate 10 is located in the openings of the first heat dissipation groove 4 and the second heat dissipation groove 5, and corresponds to the setting position of the air guide hole 9. It is used to block and guide the airflow discharged from the air guide hole 9 to prevent the airflow from directly impacting the patient and causing discomfort.

[0029] In this embodiment, multiple groups of first heat dissipation slots 4 and second heat dissipation slots 5 are provided on the top outer wall of the head protection pad 3. The multiple groups of first heat dissipation slots 4 and the multiple groups of second heat dissipation slots 5 are intertwined and connected with each other, which can not only reduce the contact area between the head and the protection pad, but also reserve channels for air flow, thereby preliminarily alleviating the problem of stuffiness.

[0030] In this embodiment, multiple groups of air guide holes 9 are opened at the bottom of the head protection pad 3, and the diameter of the air guide holes 9 is larger than the width of the first heat dissipation slot 4 and the second heat dissipation slot 5, which can reduce the airflow resistance and ensure the heat dissipation efficiency; at the same time, the opening positions of the multiple groups of air guide holes 9 all correspond to the positions where the first heat dissipation slot 4 and the multiple groups of second heat dissipation slots 5 are connected, and a protective plate 10 is provided above the air guide holes 9 that are connected to the first heat dissipation slot 4 and the multiple groups of second heat dissipation slots 5, so that the airflow can accurately enter the first heat dissipation slot 4 and the multiple groups of second heat dissipation slots 5 and be effectively guided.

[0031] Illustratively, the width of the protective plate 10 is greater than the diameter of the air guide hole 9, which can effectively diffuse the airflow to the first heat dissipation slot 4 and multiple groups of second heat dissipation slots 5; and the thickness of the protective plate 10 is less than the depth of the first heat dissipation slot 4 and multiple groups of second heat dissipation slots 5, which neither hinders the ventilation function of the heat dissipation slot nor blocks or guides the airflow.

[0032] The air guide mechanism in this embodiment includes an air guide groove 7 and a diversion groove 8; Among them, the air guide groove 7 is opened in the bottom of the head support seat 2 and corresponds to the position of the fan 6, serving as the main air flow channel; A plurality of shunt grooves 8 are provided in the bottom of the head support seat 2. The shunt grooves 8 are connected to the air guide holes 9 and the air guide grooves 7 to distribute the air flow from the air guide grooves 7 to the air guide holes 9. Specifically, the air guide groove 7 and the diversion groove 8 are both larger than the air guide hole 9 , which can form a certain airflow pressure to ensure that the airflow can smoothly pass through the air guide hole 9 into the interior of the head protection pad 3 .

[0033] In this embodiment, an air flow slot 60 corresponding to the fan 6 is opened on the mounting plate 1, and the width and length of the air flow slot 60 are both larger than the fan 6, which can ensure that the fan 6 can inhale sufficient air from the outside.

[0034] Through the coordinated cooperation of the above-mentioned components, the fan 6 is started during radiotherapy, and the air enters the air guide groove 7 through the air flow groove 60, and then enters the head protection pad 3 through the diversion groove 8 and the air guide hole 9. Under the guidance of the protective plate 10, the air flow is dispersed to the first heat dissipation groove 4 and the second heat dissipation groove 5 that are intertwined with each other, taking away the heat and sweat moisture from the head, significantly improving the patient's comfort, reducing the restlessness caused by stuffiness, and ensuring body position stability.

[0035] It should be noted that the model, power, material, etc. of the fan 6 are all suitable for the medical environment (this is a well-known technology and will not be elaborated here). At the same time, in winter, it can be started according to actual needs. When operating in winter, the fan 6 is used to draw heat from the first heat dissipation groove 4 and the second heat dissipation groove 5 into the air guide groove 7, and discharge it through the air flow groove 60 to dissipate heat.

[0036] The working principle of the present invention is as follows: During tumor radiotherapy, the device is first fixed to a designated position of the radiotherapy equipment via the mounting plate 1, providing stable support for the overall structure; the patient's head is placed on the head protection pad 3 of the head support seat 2. The head protection pad 3 adopts an ergonomic design that adapts to the curve of the head. It can not only effectively fix the patient's head position to ensure that the radiotherapy rays are accurately focused on the target area, but also reduce the patient's sense of pressure through the soft material; Because the outer wall of the head protection pad 3 is provided with multiple groups of first heat dissipation slots 4 and second heat dissipation slots 5 that are intertwined and interconnected, these slots not only reduce the contact area between the head and the protection pad, but also reserve channels for airflow, thereby preliminarily alleviating the problem of stuffiness. At the same time, the protective plate 10 embedded in the outer wall of the head support seat 2 is located within the openings of the first heat dissipation slots 4 and the second heat dissipation slots 5, and corresponds to the position of the air guide holes 9. This neither hinders the ventilation function of the heat dissipation slots nor guides the subsequent discharged airflow, thereby preventing the airflow from directly impacting the patient and causing discomfort. When the patient starts radiotherapy, the fan 6 on the head support seat 2 is started, and the fan 6 draws air from the outside through the air flow slot 60 on the mounting plate 1. Since the width and length of the air flow slot 60 are larger than the fan 6, sufficient air intake can be ensured; the inhaled air flows into the air guide slot 7 at the bottom of the head support seat 2, and the air guide slot 7 serves as the main air flow channel, distributing the cold air to the multi-component flow slots 8; Subsequently, the diverter groove 8 evenly guides the airflow to the multiple groups of air guide holes 9 at the bottom of the head protection pad 3. Since the air guide groove 7 and the diverter groove 8 are larger than the air guide holes 9, a certain airflow pressure is generated to ensure that the airflow can smoothly pass through the air guide holes 9 and enter the interior of the head protection pad 3. After the airflow passes through the air guide holes 9, it is blocked and guided by the protective plate 10 and dispersed into the first heat dissipation slots 4 and the second heat dissipation slots 5 that are staggered with each other; due to the staggered design of the first heat dissipation slots 4 and the second heat dissipation slots 5, the airflow can cover most of the area where the patient's head contacts the head protection pad 3, and the heat and sweat moisture generated by the head are taken away by the airflow, thereby reducing the local temperature and keeping it dry, significantly improving the patient's comfort during long-term radiotherapy, reducing restlessness caused by stuffiness, and ensuring body position stability.

The specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiment without creative contribution as needed without departing from the principles and purpose of the present invention.
