Description

Technical Field

[0001] The present invention relates to the technical field of radiotherapy auxiliary equipment, and in particular to a radiotherapy-specific blanket and a heat preservation equipment used for heat preservation of tissue equivalents. Background Art

[0002] When radiotherapy is used to treat tumors, high-energy radiation is used. High-energy radiation has the characteristic of building effect. If the treatment site is located on the superficial surface of the skin, it will lead to insufficient surface radiation dose, which will lead to poor tumor control effect and easy recurrence. To solve this problem, tissue equivalent compensators are often used clinically to cover the surface of the patient's skin. This can effectively increase the superficial target dose and obtain satisfactory treatment results.

[0003] Since the temperature in the radiotherapy room is relatively low, the temperature of the tissue equivalents stored in the room is close to the room temperature of the room. When used on patients, the tissue equivalents are attached to the exposed skin of the patient. The cold tissue equivalents can easily cause irritation, chills, shaking and other reactions in the patient. In the prior art, there is a method of using a warming box to heat the tissue equivalents to reduce the patient's discomfort, but the warming box needs to be powered on. The warming box based on the electric heating principle affects the temperature balance in the room and poses a safety hazard to the expensive medical equipment in the room.

[0004] Therefore, the prior art still needs to be improved and developed. Summary of the invention

[0005] In order to solve the problem in the prior art that the temperature in the radiotherapy room is low and the tissue equivalents stored in the room are cold, which can easily cause irritation, chills, tremors and other discomforts to the patient when they are in contact with the patient's exposed skin, the use of a warming box to warm the tissue equivalents can solve the patient's adverse reactions, but the electric warming box affects the temperature balance of the room and poses a safety hazard to the expensive medical equipment in the room.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0029] Since the temperature in the radiotherapy room is relatively low, the temperature of the tissue equivalents stored in the room is close to the room temperature of the room. When used on patients, the tissue equivalents are attached to the exposed skin of the patient. The cold tissue equivalents can easily cause irritation, chills, shaking and other reactions in the patient. In the prior art, there is a method of using a warming box to heat the tissue equivalents to reduce the patient's discomfort, but the warming box needs to be powered on. The warming box based on the electric heating principle affects the temperature balance in the room and poses a safety hazard to the expensive medical equipment in the room.

[0030] Based on the above problems in the prior art, the present invention provides a radiotherapy blanket for tissue equivalents, such as Figure 1 As shown, the radiotherapy blanket for tissue equivalents includes: a blanket body 100, which includes a thermal conductive layer 110 and an isolation layer 120; a closed opening 130 is provided on the isolation layer 120 on a side away from the thermal conductive layer 110, and the closed opening 130 can be opened or closed, and a corresponding area on the thermal conductive layer 110 and the isolation layer 120 form a placement cavity 200, and the placement cavity 200 is used to store tissue equivalents 400.

[0031] The present invention sets an openable and closable closed opening 130 on one side of the isolation layer 120 of the subject 100, and cooperates the thermal conductive layer 110 and the isolation layer 120 in the area corresponding to the closed opening 130 to form a placement cavity 200 for storing the tissue equivalent 400 to be used. When different patients undergo radiotherapy, some patients do not need to use the tissue equivalent 400, but all patients need to cover the exposed skin for heat preservation during the preparation period. By using the patient's own body temperature to increase the temperature of the tissue equivalent 400, when the tissue equivalent 400 needs to be used, it can avoid causing the patient to have reactions such as irritation, chills, and tremors. The present invention does not require an additional heating structure, does not have a safety hazard, does not occupy treatment space, and can improve the comfort of the patient during radiotherapy.

[0032] In the above embodiment, if Figure 1As shown, the main body of the radiotherapy blanket for keeping the tissue equivalent 400 warm is a blanket body 100, which is composed of a thermal conductive layer 110 and an insulating layer 120, wherein the thermal conductive layer 110 is in contact with the exposed skin of the patient, and is used to keep the exposed skin of the patient warm before radiotherapy, so as to avoid complications of the patient induced by low temperature; the insulating layer 120 is arranged on the other side of the thermal conductive layer 110 away from the human body, and the insulating layer 120 is made of a material with low thermal conductivity efficiency, and is used to reduce the heat transfer between the machine room space and the thermal conductive layer 110, so as to keep the exposed body of the patient warm. In this embodiment, the combined thermal conductive layer 110 and the insulating layer 120 can collect the temperature of the covered parts of the patient to a certain extent, thereby reducing the heat loss on the patient's body surface. Based on the characteristics of the thermal conductive layer 110 and the thermal insulating layer, in this embodiment, a closed opening 130 is further provided on the side of the insulating layer 120 away from the thermal conductive layer 110. The closed opening 130 can be opened or closed. In the specific setting, a placement cavity 200 is formed in the area corresponding to the closed opening 130 on the thermal conductive layer 110. The tissue equivalent 400 can be placed in the placement cavity 200 through the closed opening 130, so that the tissue equivalent 400 is indirectly heated by the patient's body temperature collected by the body 100. The temperature of the heated tissue equivalent 400 is close to the human body temperature. Therefore, when used, it can avoid causing irritation, chills, and shaking in the patient.

[0033] During radiotherapy, tissue equivalent 400 (also known as radiotherapy compensator, Bolus, etc.) is used to increase the dose of superficial parts in radiotherapy. When photon rays (such as 6MV X-rays) irradiate the human body, the maximum dose point is not on the surface of the body, but at a certain depth in the body. This area is called the dose built-up area. If the target area is shallow, the dose of the target area may be insufficient, so it is necessary to place an object with a density similar to that of the human body on the surface of the body to increase the dose of the superficial parts. This object is the tissue equivalent 400. Since the radiotherapy conditions of different patients are different, not all patients need to use tissue equivalent 400, but all patients need to keep their exposed skin warm before radiotherapy. Therefore, in this embodiment, by covering the exposed skin of the patient with the quilt 100, the effect of heating the tissue equivalent 400 in the placement cavity 200 can be achieved, and the temperature of the tissue equivalent 400 when used can be guaranteed to be close to the temperature of the human body, avoiding irritation to the patient due to excessive temperature difference.

[0034] Specifically, Figure 1As shown, in order to make the above-mentioned thermal conductive layer 110 have a higher heat transfer efficiency to the tissue equivalent 400 placed in the cavity 200, in the present embodiment, an identification portion 300 is further provided on the side of the isolation layer 120 away from the thermal conductive layer 110. The identification portion 300 corresponds to the position of the cavity 200, and is used to facilitate medical staff to quickly know the position where the tissue equivalent 400 is placed, so that when covering the patient's skin, the part corresponding to the identification portion 300 can be targeted to cover the patient, that is, the corresponding area between the tissue equivalent 400 and the human skin is increased as much as possible, so as to improve the heating efficiency of the tissue equivalent 400.

[0035] In this embodiment, the length and width of the above-mentioned marking part 300 should be greater than the length and width of the placement cavity 200, so that the marking part 300 is relatively conspicuous, which is convenient for medical staff to quickly identify the location of the placement cavity 200 from the folded or curled quilt 100. In addition, the color of the above-mentioned marking part 300 and other parts of the isolation layer 120 can be set to be different, so as to facilitate medical staff to identify, and / or the texture of the marking part 300 and other parts of the isolation layer 120 is different, and / or the material used for the marking part 300 and other parts of the isolation layer 120 is different, etc. Through the above-mentioned different structural settings, it can be convenient for medical staff to quickly distinguish the location of the marking part 300.

[0036] Furthermore, if Figure 1 As shown, a connecting piece is provided on the closed opening 130, and the connecting piece is used to connect the two open sides of the closed opening 130 to achieve the effect of opening or closing the closed opening 130 through the connecting piece. In a specific embodiment of the present invention, the connecting piece can be specifically set to Velcro, that is, the two parts of the Velcro are respectively attached to the two sides of the closed opening 130, and the Velcro can be used to achieve the effect of repeated opening or closing, thereby meeting the needs of medical staff to take and place the tissue equivalent 400.

[0037] In another specific embodiment of the present invention, the above-mentioned connecting member can also be specifically configured as a zipper, that is, the two locking tracks of the zipper are respectively fixedly arranged on both sides of the closed opening 130, and the zipper is used to achieve the effect of repeated opening or closing, thereby meeting the needs of medical staff to take and place the tissue equivalent 400.

[0038] In another embodiment of the present invention, Figure 1 and Figure 2 As shown, the shapes of the thermal conductive layer 110 and the insulating layer 120 are adapted, and the thermal conductive layer 110 and the insulating layer 120 are fixedly connected except for the placement cavity 200, so as to form a Figure 2 In the structural style shown, the thermal conductive layer 110 has a better thermal conductive effect and can conduct the temperature of the patient's body surface.

[0039] At the location on the body 100 corresponding to where the cavity 200 is placed, the thermal conductive layer 110 continuously conducts heat between the patient's body temperature and the tissue equivalent 400 until the temperature of the tissue equivalent 400 is close to the patient's body temperature. The isolation layer 120 on the other side of the tissue equivalent 400 isolates the tissue equivalent 400 from heat exchange with the air, thereby achieving the effect of maintaining the temperature of the tissue equivalent 400.

[0040] At the location on the body 100 that does not correspond to the placement of the cavity 200, the thermal conductive layer 110 conducts the patient's body temperature to the isolation layer 120. However, since the heat exchange efficiency of the isolation layer 120 is low, the conducted temperature is stored on the thermal conductive layer 110 and reacts to the patient's body surface, thereby achieving the effect of keeping the patient warm.

[0041] In specific settings, such as Figure 2 As shown, the thickness of the above-mentioned thermal conductive layer 110 should be greater than the thickness of the isolation layer 120. The purpose of such a setting is to allow a certain amount of air flow inside the thermal conductive layer 110, thereby avoiding the patient from feeling stuffy when keeping warm. Specifically, the thermal conductive layer 110 is made of breathable material, such as wool, silk, cotton and linen, etc., which can have both thermal insulation and breathability. At the same time, since the thermal conductive layer 110 is in contact with different patients, the easy cleaning and disinfection of the surface should also be considered in the actual setting. In a specific embodiment, the surface density of the thermal conductive layer 110 can be increased by weaving the silk into multiple branches, so that it can be easily cleaned and disinfected by disinfectants such as alcohol.

[0042] In addition, the thermal conductive layer 110 and the isolation layer 120 are both made of flexible materials. The purpose of this arrangement is to enable the quilt 100 to better adapt to the shape of the skin when covering the patient's skin, thereby fitting the skin and improving the thermal insulation efficiency. The four corners of the quilt 100 should be smoothly chamfered to avoid sharp corners scratching the patient's skin and causing irritation.

[0043] Furthermore, the placement cavity 200 should be arranged at the center of the body 100. This is because the thermal conductive layer 110 has a certain degree of air permeability, and the surrounding areas of the body 100 will exchange heat with the air due to the air permeability. The heat in the placement cavity 200 located at the center of the body 100 is not easy to dissipate, and the effect of keeping the tissue equivalent 400 warm can be better achieved.

[0044] In a specific embodiment, the placement cavity 200 is preferably configured as a rectangle, and the length and width of the placement cavity 200 should be greater than or equal to 30 cm. The reason for this configuration is that the conventional cross-sectional size of the tissue equivalent 400 in the prior art is a rectangle of 30*30 cm. By configuring a placement cavity 200 adapted to the tissue equivalent 400, on the one hand, the tissue equivalent 400 can be flattened to make the patient more comfortable when covered with the quilt 100 for insulation. On the other hand, the contact area between the tissue equivalent 400 and the thermal conductive layer 110 can be increased as much as possible, thereby achieving higher heating efficiency.

[0045] Based on the above embodiment, the actual use process of the radiotherapy blanket for keeping the tissue equivalent 400 warm is as follows:

[0046] First, the medical staff places the tissue equivalent 400 in the placement cavity 200 of the object 100 through the closed port 130;

[0047] During the preparation for radiotherapy of the patient, the body 100 is covered on the exposed skin of the patient according to the area corresponding to the marking part 300, and the heat of the patient's skin is conducted to the placement cavity 200 through the thermal conductive layer 110, and the tissue equivalent 400 is heated and stored back on the patient's skin, so that the temperature of the tissue equivalent 400 is increased to a temperature close to that of the human body while the patient is kept warm;

[0048] When the patient is undergoing radiotherapy, if tissue equivalent 400 is needed, medical staff can take out the tissue equivalent 400 in the placement cavity 200 for use. Since the temperature of the tissue equivalent 400 is similar to that of the human body, it will not cause irritation to the patient, thus avoiding chills, tremors, etc. in the patient, thereby ensuring the accurate implementation of radiotherapy.

[0049] When the patient is receiving radiotherapy, if the tissue equivalent 400 is not needed, there is no need to remove the tissue equivalent 400 .

[0050] Based on the above embodiments, the present invention also provides a thermal insulation device, which includes the radiotherapy blanket for thermal insulation of tissue equivalents in the above embodiments, and the radiotherapy blanket for thermal insulation of tissue equivalents includes: a blanket body, the blanket body includes a thermal conductive layer and an isolation layer; a closed opening is provided on the side of the isolation layer away from the thermal conductive layer, and the closed opening can be opened and closed, and the area on the thermal conductive layer corresponding to the closed opening forms a placement cavity with the isolation layer, and the placement cavity is used to store tissue equivalents.

[0051] The present invention sets an openable and closable closed opening on one side of the isolation layer of the subject, and cooperates the thermal conductive layer and the isolation layer in the area corresponding to the closed opening to form a placement cavity for storing tissue equivalents to be used. When different patients undergo radiotherapy, some patients do not need to use tissue equivalents, but all patients need to cover the exposed skin for heat preservation during the preparation period. By using the patient's own body temperature to increase the temperature of the tissue equivalent, when the tissue equivalent needs to be used, it can avoid causing the patient to have reactions such as irritation, chills, and tremors. The present invention does not require an additional heating structure, does not have any safety hazards, does not occupy treatment space, and can improve the comfort of the patient during radiotherapy.

[0052] It should be understood that the application of the present invention is not limited to the above examples. For ordinary technicians in this field, improvements or changes can be made based on the above description. All these improvements and changes should fall within the scope of protection of the claims attached to the present invention.
