[0064] Example 1

[0065] Reference Figure 1 and Figure 2 , as a first embodiment of the present invention, a radiotherapy positioning pad is provided, the device comprising:

[0066] The pad body 100 includes a fixing seat 101, a connecting frame 102 disposed inside the fixing seat 101, and a memory pad 103 disposed inside the connecting frame 102;

[0067] By placing the patient's head and body on the memory pad 103, it can provide support;

[0068] The identification device 200 connected to the pad body 100 includes a body 201, a display panel 202 located on the surface of the body 201, and an identifier 203 disposed below the display panel 202;

[0069] By using the identification device 200, the patient's identity can be read and the patient's information can be output;

[0070] as well as,

[0071] The plug wire 300 is used to connect the pad body 100 and the identification device 200 .

[0072] The pad body 100 also includes a pressure detection module 104 and an execution module 105;

[0073] The pressure detection module 104 is used to collect the pressure on each point of the memory pad 103;

[0074] The execution module 105 is used to control the memory pad 103 to deform;

[0075] After the patient lies on the memory pad 103, the pressure of each part can be collected through the built-in pressure detection module 104, and the memory pad 103 is divided into multiple groups of independently controlled independent areas, each group of independent areas is controlled by a brake to achieve deformation control of the memory pad 103.

[0076] The identification device 200 includes a data analysis module 204;

[0077] The data analysis module 204 is used to receive the data from the pressure detection module 104 and transmit the analyzed data to the execution module 105;

[0078] The data analysis module 204 is also connected to the database to upload the information to the cloud platform;

[0079] The database cloud service can ensure that patient information can be synchronized through the database when patients seek medical treatment in different hospitals.

[0080] During use, the patient first identifies information through the identifier 203, for example, through face recognition of the patient's facial features, and then reads the corresponding patient data in the database. After successful reading, all patient information is displayed on the display panel 202, and the patient information is analyzed and then transmitted to the execution module 105. The execution module 105 controls the memory pad 103 to deform so that it can better fit the patient's body, making it easier for the doctor to fix the patient.

[0081] Example 2

[0082] Reference Figure 3 , which is the second embodiment of the present invention, and which is different from the first embodiment in that: a method for using a radiotherapy positioning pad is provided, comprising:

[0083] S1. Collect patient information through the identifier 203.

[0084] The specific steps of the identifier 203 collecting patient information include:

[0085] Enter patient data and transfer patient data to database;

[0086] Compare the patient data with the database to determine whether there is existing patient data;

[0087] When there is patient data in the database, the patient information is displayed through the display panel 202, and the patient is reminded to check the patient information;

[0088] When patient data does not exist in the database, complete patient information is entered;

[0089] Among them, the patient data is any data in the patient information, and the patient information includes: facial information, adjustment data, fingerprint information, ID number, medical number, and name.

[0090] Among the patient information, ID number, medical number, adjustment data and name are necessary information;

[0091] Among the patient information, facial information and fingerprint information are secondary information;

[0092] When entering patient data, the patient enters a fingerprint or face, and the patient's identity is collected through fingerprint recognition or face recognition;

[0093] When the collection fails, the patient's identity is collected through the ID number or medical number, and all the patient information is displayed on the display board 202 for patient verification;

[0094] When the collection is successful, all the patient information is displayed on the display panel 202 for the patient's verification;

[0095] After successful patient verification, the patient information is transmitted to the data analysis module 204 .

[0096] S2. Analyze the patient information through the data analysis module 204 to obtain identification results and execution results.

[0097] The steps of analyzing the patient information by the data analysis module 204 include:

[0098] Determine whether the number of days corresponding to the adjustment data in the patient information is greater than the set value K;

[0099] When the number of days corresponding to the adjustment data is greater than the set value K, data prediction is performed;

[0100] When the number of days corresponding to the adjustment data is not greater than the set value K, the output execution result is none;

[0101] The data prediction step includes:

[0102] The input date is the forecast date, the N days closest to the forecast date are the core days, and the M days before the core days are the important days;

[0103] Determine whether the adjustment data of the core days is missing. If it is missing, the output execution result is None. If it is not missing, determine whether the missing data of the important days is less than the threshold Z. If it is less than the threshold Z, perform secondary prediction. If it is not less than the threshold Z, the output execution result is None.

[0104] In this embodiment, the setting value K is 8 days, the core days N is 3 days, and the important days M is 2 days;

[0105] For example, if today's date is October 10, 2024, the number of days with adjusted data in the patient information is 10 days, which is greater than the set value K, that is, 10 days is greater than 8 days, then data prediction is performed. If the number of days with adjusted data in the patient information is 5 days, it means that the data is too small to make an effective prediction, so the output execution result is None;

[0106] When predicting data, today (October 10, 2024) is used as the prediction date, and the three days closest to the prediction date are used as core days, namely October 9, 2024, October 8, 2024, and October 7, 2024. It is determined whether there is any missing adjustment data in these three days. If there is no adjustment data on October 8, 2024, it means that this group of data cannot be effectively predicted, so the output execution result is None. If the data of these three days is complete and there is no missing data, then effective prediction can be made, that is, it is determined whether the missing data of important days is less than the threshold Z.

[0107] Assume that the threshold Z is 2, and the dates of the important days M are October 6, 2024 and October 5, 2024. When the number of days with missing data in the important days is less than 2 days, in the case of this embodiment, one of the days is missing or not missing, and a secondary prediction is performed. When the number of days with missing data in the important days is not less than 2 days, in the case of this embodiment, both days are missing, and no effective prediction can be performed, that is, the output execution result is none.

[0108] The steps of the secondary prediction include:

[0109] A prediction calculation formula is introduced, and predicted adjustment parameters are obtained through the prediction calculation formula, and the predicted adjustment parameters are transmitted to the execution module 105 as execution results.

[0110] The calculation formula is expressed as,

[0111] y=β0+β1χ+∈;

[0112] In the formula, y represents the adjustment parameter of the prediction, χ represents the number of days, β0 represents the intercept, β1 represents the slope, and ∈ represents the error term;

[0113] Among them, the calculation formula of slope β1 is expressed as:

[0114]

[0115] The calculation formula of intercept β0 is expressed as:

[0116]

[0117] In the formula, Expressed as the mean of days, It is expressed as the parameter mean, n is the sum of the core days N days and the important days M days;

[0118] Mean of days The calculation formula is:

[0119]

[0120] The mean of the parameters The calculation formula is:

[0121]

[0122] In the formula, x i Represented as the number of the i-th day, y i Represented as the adjustment parameter for the i-th day.

[0123] In the specific implementation process, the adjustment data of the patients in the database are shown in Table 1;

[0124] Table 1: Patient's adjustment data information table

[0125]

[0126] First, we need to calculate the mean of the days x and the mean of the parameters Take the first block of pressure values ​​as an example and substitute it into the average value of the days The calculation formula is: Substitute into the parameter mean The calculation formula is:

[0127] Then substitute it into the calculation formula of slope β1, and the result is 1;

[0128] Substitute it into the calculation formula of intercept β0, and the result is 84;

[0129] Finally, all the data are put into the prediction calculation formula, and the result is y=94, which means that the prediction result of the first pressure value on October 10, 2024 is 94;

[0130] At this point, the output execution result is that the pressure value of the first block is adjusted to 94. According to the same method, the pressure values ​​of all areas are predicted and calculated in turn, and finally the complete execution result is output.

[0131] S3, judging whether to deform the memory pad 103 according to the recognition result;

[0132] When the memory pad 103 needs to be deformed, the memory pad 103 is operated to deform through the execution module 105;

[0133] When the memory pad 103 does not need to be deformed, there is no response;

[0134] When the memory pad 103 is deformed, the complete execution result will be output, and after the individual brakes in each area of ​​the memory pad 103 receive the corresponding execution result, the deformation of the memory pad 103 is completed, and the patient can then lie directly on the memory pad 103.

[0135] Combined with Figures 1 to 3 As shown, during each radiotherapy, the pressure on the memory pad is collected and used for the next prediction calculation, and the memory pad can be automatically adjusted according to the prediction results, which can reduce treatment deviations caused by improper body position, thereby reducing potential damage to surrounding healthy tissues. Secondly, it can reduce treatment interruptions and repeated treatments caused by manual adjustments, and can make more efficient use of medical resources. In combination with face recognition or fingerprint recognition, the patient only needs to complete the identification of identity information before the operation to automatically complete the adjustment of the memory pad.
