Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

The present embodiment provides a method for detecting a close-contact person, which is applied to a hospital platform, as shown in fig. 1, the main flow of the method is described as follows (steps S101 to S102):

step S101: acquiring personal information and treatment information of the hospitalized personnel, and classifying infectious disease patients and common patients based on the personal information and the treatment information.

In this embodiment, the personal information and the medical information stored in the storage module are acquired by reading the storage module.

The personal information comprises personal basic information and a personnel number of the person who is admitted, and the personnel number in the personal information read from the storage module is a first number; the information of seeing a doctor is the relevant information of the infectious patient, the information of seeing a doctor also includes the personnel number of the infectious patient, and the personnel number is the second number. Comparing the second number with the first number in sequence; and if the second number is the same as the first number, classifying the hospitalized personnel corresponding to the first number as the infectious disease patients. After the comparison is completed, the remaining hospital admissions are classified as general patients.

Step S102: indoor track information is acquired, and close contact persons of each infectious disease patient are detected based on the indoor track information of the infectious disease persons and the indoor track information of the common patients.

In this embodiment, the indoor trajectory information stored in the storage module is acquired by reading the storage module.

The indoor track information comprises tag information and reading time; the tag information comprises tag information to be detected and reference tag information, the tag information to be detected is the information of the tag to be detected read by the reader-writer, and the reference tag information is the information of the reference tag read by the reader-writer; the label to be detected is carried by the hospital admission personnel, and the reference label is preset in each area of the hospital; the reading time is the time point when the reader reads the label to be detected.

And obtaining the position coordinates of the hospitalized personnel in the hospital room based on the information of the label to be detected and the information of the reference label by adopting an RFID personnel positioning algorithm based on scene analysis.

The personal information and the to-be-detected label information both comprise to-be-detected label numbers, the to-be-detected label information further comprises electronic label information, and position coordinates of the hospitalized personnel in the hospital room are calculated and obtained based on the electronic label information and the reference label information.

The method comprises the steps that a to-be-detected label number in personal information stored in a storage module is used as a first label number, and a to-be-detected label number in the to-be-detected label information stored in the storage module is used as a second label number, so that the first label number is obtained by reading the personal information in the storage module; and reading the information of the tag to be detected in the storage module to obtain a second tag number.

Comparing the second label number with the first label number in sequence; and if the second label number is the same as the first label number, determining that the position coordinates obtained through the electronic label information corresponding to the second label number are the coordinates of the hospitalized person corresponding to the first label number, and further obtaining the position coordinates of the infectious disease person and the common patient according to the first number and the second number.

The position coordinates correspond to the reading time one by one, the position coordinates correspond to the persons who are admitted, and correspondingly, the reading time corresponds to the persons who are admitted, so that the reading time of the infectious disease persons and the reading time of the common patients can be obtained.

Next, based on the indoor track information of the infectious patients and the ordinary patients, the close contact person of each infectious patient is detected, and the specific methods mainly include two types: first, a method of detecting the presence of an infectious disease person and a general patient in the same area, and second, a method of detecting the absence of an infectious disease person and a general patient in the same area.

The method for judging whether the infectious disease person and the common patient are in the same region comprises the following steps:

referring to fig. 2, position coordinates and reading time of a person who is admitted are acquired, the position coordinates acquired for the first time are taken as effective coordinates, and the reading time corresponding to the position coordinates acquired for the first time is taken as arrival time corresponding to the effective coordinates; wherein the arrival time is a time point when the hospitalized person arrives at the effective coordinates.

Comparing the position coordinates acquired twice in sequence; if the position coordinates are different from the effective coordinates, the position coordinates acquired later are also used as effective coordinates, the reading time corresponding to the position coordinates acquired later is used as the arrival time corresponding to the position coordinates acquired later, and meanwhile, the reading time corresponding to the position coordinates acquired later is used as the departure time corresponding to the position coordinates acquired earlier; wherein the leaving time is a point in time at which the admit person leaves the valid coordinates.

Determining an area passed by the hospitalized person, an initial coordinate in the area, an initial time for entering the area, an end coordinate in the area and an end time for leaving the area according to the effective coordinate of the hospitalized person; the initial coordinate is a position coordinate when the hospitalized person enters the area on the premise that the hospitalized person is continuously located in the same area, the tail coordinate is a position coordinate when the hospitalized person leaves the area on the premise that the hospitalized person is continuously located in the same area, the initial time is the arrival time corresponding to the initial coordinate, and the tail time is the leaving time corresponding to the tail coordinate.

And acquiring an activity time period based on the initial time and the end time of the region, wherein the activity time period is the time when the hospitalized personnel are continuously located in the same region, and the time period formed by the initial time and the end time is the activity time period.

Determining the areas where the infectious patients pass according to the initial coordinates and the tail coordinates, and acquiring the activity time period of the infectious patients in each area according to the initial time and the tail time; similarly, the areas that the ordinary patient passes through and the activity time period in each area are determined.

Judging whether the infectious disease person and the common patient pass through the same area or not, wherein the activity time periods in the area are overlapped; if yes, the infectious disease person and the general patient are judged to be in the same area, and the area is called as a same area.

After judging that the infectious disease person and the common patient are in the same region, the detection method of the close contact person is divided into three methods, specifically as follows:

(1) detection methods based on cumulative contact time.

The overlapping parts of the activity time periods of the infectious patients in the same area and the activity time periods of the common patients in the area are added in an accumulated mode to obtain accumulated contact time.

Judging whether the accumulated contact time is greater than a preset time threshold value or not; if so, the common patient is determined to be in close contact with the patient.

It is noted that an infectious disease person and a general patient may continuously come together in two or more areas, and thus the cumulative contact time refers to the time the infectious disease person and the general patient are in contact at all times after judging that the infectious disease person and the general patient are in the same area. For example, if an infectious disease person and a general patient are located in the room 2 and then in the room 3, the cumulative contact time refers to the time when the infectious disease person and the general patient are located in the room 2 and the room 3.

Further, the level of infection of the close contact is determined based on the interval to which the cumulative contact time belongs. For example, whether the accumulated contact time is greater than a first preset time threshold is judged; if yes, judging the infection grade of the close contact person to be high grade; judging whether the accumulated contact time is not more than a first preset time threshold and is more than a second preset time threshold; if yes, judging the infection grade of the close contact person to be a middle grade; judging whether the accumulated contact time is not more than a second preset time threshold and is more than a third preset time threshold; if yes, judging the infection grade of the close contact person to be low; wherein the preset time threshold is equal to a third preset time threshold.

The probability of the close contact person being infected can be estimated from the infection level, where a high level indicates that the close contact person is infected with a high probability, a middle level indicates that the close contact person is infected with a high probability, and a low level indicates that the close contact person is infected with a low probability.

(2) Distance-based detection methods.

Referring to fig. 3, the time period is obtained based on the arrival time and the departure time of the effective coordinates; the time period is the time when the hospitalized person is continuously in the effective coordinates, and the time period formed by the arrival time and the departure time is the time period.

The overlapping part of the time period of the infectious patient in the same area and the time period of the common patient in the area is used as the same time period.

And acquiring effective coordinates of the infectious disease patient and the common patient in the same time period, and calculating the distance between the infectious disease patient and the common patient based on the two effective coordinates. The distance represents the distance between the infectious disease person and the common patient in the same period of time and the distance at the same time, and the specific calculation formula is as follows:

wherein d represents the distance, x_aX-axis coordinate, y, representing the effective coordinate of the location of the infected patient_aY-axis coordinate, x, representing the effective coordinate of the location of the infected patient_bX-axis coordinate, y, representing the effective coordinates of a typical patient_bIndicates the general patient is inY-axis coordinates of the effective coordinates of (a).

Judging whether the distance is smaller than a preset distance threshold value or not; if so, the common patient is determined to be in close contact with the patient.

It is noted that when a plurality of distances are acquired between an infectious disease person and a general patient, the general patient is determined to be a close contact person as long as one of the distances is less than a preset distance threshold.

At present, the frequency and the precision of the obtained position coordinates are adjustable by adopting a RFID personnel positioning algorithm based on scene analysis, if the frequency and the precision are very high and the personnel in hospital move, an effective coordinate can be obtained within a few seconds, correspondingly, the calculation amount of the distance is large, and the calculation pressure is heavy. At this time, the distance between an infectious disease person and a general patient in the same area can be acquired at preset time intervals to reduce the calculation pressure.

Further, the infection level of the close contact person is determined according to the interval to which the distance belongs. For example, whether the distance is smaller than a first preset distance threshold value is judged; if yes, judging the infection grade of the close contact person to be high grade; judging whether the distance is not less than a first preset distance threshold and is less than a second preset distance threshold; if yes, judging the infection grade of the close contact person to be a middle grade; judging whether the distance is not less than a second preset distance threshold and is less than a third preset distance threshold; if yes, judging the infection grade of the close contact person to be low; wherein the preset distance threshold is equal to a third preset distance threshold.

(3) A detection method based on a co-located time period and a distance.

Obtaining a co-located time period and a distance between the co-located time period and the co-located time period according to the method (2), and judging whether the co-located time period is greater than a time threshold value or not and the distance is less than a distance threshold value; if so, the common patient is determined to be in close contact with the patient.

Further, the infection level of the close contact person is determined according to the interval to which the period of the same place belongs and the interval to which the distance belongs. For example, determining whether the period of the co-location time is greater than a first time threshold and the distance is less than a first distance threshold; if yes, judging the infection grade of the close contact person to be high grade; judging whether the same time period is not greater than a first time threshold and is greater than a second time threshold, and meanwhile, the distance is smaller than a first distance threshold; if yes, judging the infection grade of the close contact person to be a middle grade; judging whether the distance is not less than a first distance threshold value and is less than a second distance threshold value, and meanwhile, the same time period is greater than a first time threshold value; if yes, judging the infection grade of the close contact person to be a middle grade; judging whether the same time period is not more than a first time threshold and is more than a second time threshold, and meanwhile, whether the distance is not less than the first distance threshold and is less than the second distance threshold; if yes, judging the infection grade of the close contact person to be low; wherein the time threshold is equal to the second time threshold and the distance threshold is equal to the second distance threshold.

Secondly, the detection method for infectious disease people and common patients who are not in the same region specifically comprises the following steps:

judging whether a common patient enters the area within a preset time after the infectious patient leaves the passing area according to the passing area of the infectious patient in the hospital and the activity time period of each passing area, and the passing area of the common patient in the hospital and the activity time period of each passing area; if so, the common patient is determined to be in close contact with the patient.

Further, according to the preset time interval, the infection level of the close contact person is determined. For example, it is determined whether a general patient enters the area within a first preset time after the infectious patient leaves the passing area; if yes, judging the infection grade of the close contact person to be high grade; judging whether a common patient enters the area within a first preset time to a second preset time after the infectious patient leaves the passing area; if yes, judging the infection grade of the close contact person to be a middle grade; judging whether a common patient enters the area within a second preset time to a third preset time after the infectious patient leaves the passing area; if yes, judging the infection grade of the close contact person to be low; wherein the preset time is equal to a third preset time.

Optionally, the close contact person may be determined by another method, specifically, according to the area passed by the infectious patient in the hospital and the activity time period in each passed area, and the area passed by the general patient in the hospital and the activity time period in each passed area, it is determined whether there is an infectious patient leaving the area within a preset time after the general patient enters the area; if so, the common patient is determined to be in close contact with the patient. At this time, the principle of determining the infection level of the close contact person is consistent with the above-mentioned principle of determining the infection level of the close contact person according to the preset time interval, and is not described herein again.

The above-mentioned plurality of detection methods may be used in combination, and after two or more detection methods are selected, as long as any one of the detection conditions is satisfied, it is determined that the common patient is a close contact person. For example, a detection method based on accumulated contact time and a detection method based on distance are selected, wherein the result that the common patient is an osculating person is obtained by the detection method based on accumulated contact time, the result that the common patient is a non-osculating person is obtained by the detection method based on distance, and the final result is that the common patient is an osculating person.

If a common patient and an infectious patient are contacted for a plurality of times, the infection grade of the close contact person is obtained for a plurality of times, the highest infection grade is used as a final infection grade, and the final infection grade is stored in the personal record of the common patient in the data module; here, the contact means that any one of the above-described detection conditions is satisfied.

Further, the medical information includes the infectious disease grade of the infectious patient, and after the general patient is determined as the close contact person of the infectious patient, the personal information, the medical information and the infectious disease grade of the infectious patient are stored in the personal record of the general patient; wherein, the infectious disease grade is determined according to the type and the degree of the infectious disease. Determining the region grade according to the infectious disease grade of the infectious patient to facilitate the management of medical personnel, and specifically judging whether the infectious patient enters the region; if yes, the highest infectious disease grade among the infectious disease persons is taken as the regional grade.

Alternatively, for general patients who are determined to be non-close contacts, the infectious disease may be graded based on their visit information. For example, the hospitalized personnel are divided into four levels and displayed by different colors, green, yellow, orange and red, respectively; wherein green represents a no risk level; yellow for low risk rating; orange indicates a risk rating; red indicates a high risk level, and a no risk level and a low risk level indicate that the admitted person is a normal patient who is not a close contact, and a high risk level and a medium risk level indicate that the admitted person is an infectious patient or a close contact.

The zone rating is based on the highest rating of infectious disease for the hospitalized personnel entering the zone. Correspondingly, the regional grade is also four grades and is represented by four different colors, namely green, yellow, orange and red; wherein, green represents a four-level risk level, and a zone level is a four-level risk level representing that the highest level of the hospitalized personnel entering the zone is a risk-free level; yellow represents a third-level risk level, and a zone level of a third-level risk level represents that the highest level of the hospitalized personnel entering the zone is a low risk level; orange indicates a secondary risk level, a regional level being a secondary risk level indicating that the highest level of admissions to the region is a medium risk level; red indicates a primary risk level and a zone level of primary risk indicates that the highest level of admissions into the zone is a high risk level. The areas of the primary and secondary risk classes have a source of infectious disease.

If a general patient has contact with two or more infectious patients, the general patient is recorded as a close contact person of the infectious patients, and the corresponding infection grade is recorded respectively.

If two or more infectious patients are in contact with each other, the infectious patients are in close contact with each other.

Further, personal information of the close contact person is acquired, data desensitization is performed on the personal information of the close contact person, and a private announcement is sent to the close contact person based on the personal information after the data desensitization. The data desensitization may specifically adopt a symmetric encryption data desensitization method.

The hospital entrance and exit information stored in the storage module is obtained by reading the storage module; the hospital entrance and exit information comprises information of entrance and exit of the inpatient to and from the hospital.

Judging whether the infectious disease patient and the close contact person are discharged or not based on the hospital entrance and exit information; if yes, judging whether the infectious disease patient and the close contact person see a doctor again; if so, a prompt is sent to remind the staff at the door of the hospital to guide the infectious disease patient and the close contact person, so as to assist the infectious disease patient and the close contact person to go to a special passage of the hospital for diagnosis, and further avoid infecting other hospitalization personnel.

The specific method for judging whether the infectious disease patient and the close contact person see the doctor again comprises the following steps: marking the personal information of the infectious disease patient and the close contact person, matching the personal information of the admission person with the marked personal information when the admission person enters the hospital, and determining that the admission person is the infectious disease patient or the close contact person if the matching is successful.

At present, hospitals are generally multi-storey buildings, so that indoor track information also comprises reader-writer numbers, not only is information of a to-be-detected tag and a reference tag sent by a reader-writer obtained, but also the reader-writer numbers sent by the reader-writer are obtained, the obtained reader-writer numbers are matched with the reader-writer numbers stored in a storage module in advance, and floors to which position coordinates belong are determined.

In the above, the infectious disease person and the common patient are located in the same area on the premise that the infectious disease person and the common patient are located on the same floor at the same time; the areas of the infectious disease people and the common patients are determined according to the floors and the effective coordinates.

The personal information includes a first tag number to be tested and basic personal information, and the tag number to be tested in the personal information stored in the storage module 302 is used as the first tag number.

After the hospital is entered by the hospitalized person, the reader 3013 reads the tag information and stores the tag information to the storage model; the tag information includes tag information to be detected and reference tag information, the tag information to be detected is information of a tag 3011 to be detected read by the reader 3013, and the reference tag information is information of a reference tag 3012 read by the reader 3013; the reading time is a time point when the reader 3013 reads the tag to be detected 3011.

The information of the tag to be detected includes a second tag number and electronic tag information, and the tag number to be detected read by the reader 3013 and stored in the storage module 302 is used as the second tag number.

The hospital induction platform 200 reads the personal information and the tag information in the storage module 302. Obtaining a position coordinate based on the information of the tag to be detected and the information of the reference tag by adopting an RFID personnel positioning algorithm based on scene analysis; and determining the obtained position coordinate as the coordinate of which admitting person according to the first label number and the second label number, and knowing the identity of the admitting person according to the personal basic information.

At present, hospitals are generally multi-storey buildings, so the indoor track information further includes the numbers of the readers 3013, the readers 3013 send tag information to be detected and a reference tag 3012 to the storage module 302 and also send the numbers of the readers 3013 of the readers themselves, and the hospital platform 200 matches the obtained numbers of the readers 3013 with the numbers of the readers 3013 stored in the storage module 302 in advance to determine the floors to which the position coordinates belong.

The personal information also includes a person number, which is stored in the storage module 302 with the assistance of the medical staff when the hospital is entered by the hospitalized staff. The hospital platform 200 sends the personal information in the storage module 302 to the informatization system 303 for the medical personnel to view. Wherein, the personnel number in the personal information stored in the storage module 302 is used as the first number; the person number in the informatization system 303 serves as the second number.

After the hospital admission staff enters the hospital, the medical staff diagnoses the hospital admission staff to judge whether the hospital admission staff is an infectious patient, and if so, the information of the diagnosis result of the infectious patient is recorded to the information system 303. Next, the information system 303 sends the diagnosis information to the storage module 302 for storage according to the diagnosis result information; wherein the visit information includes a second number of the infected patient.

The hospital platform 200 reads the personal information and the visit information in the storage module 302, and marks out the communicable disease person and the general patient according to the first number in the personal information and the second number in the visit information, so as to obtain the indoor track information of the communicable disease person and the general patient.

The hospital platform 200 detects close contact of each infectious patient based on the indoor trajectory information of the infectious patient and the general patient.

The visit information also includes the infectious disease grade of the infected patient. After the hospital platform 200 determines that the general patient is a close contact person of the infectious patient, the individual information, the visit information and the infectious disease grade of the infectious patient are stored in the individual record of the general patient; the nosocomial platform 200 also determines the regional level based on the infectious disease level of the infectious patient; wherein, the infectious disease grade is determined by medical staff according to the type and the degree of the infectious disease and then is recorded into the information system 303.

Various changes and specific examples in the method provided by the above embodiment are also applicable to the close contact person detection system of the present embodiment, and through the foregoing detailed description of the close contact person detection method, those skilled in the art can clearly know the implementation method of the close contact person detection system in the present embodiment, and for the brevity of the description, detailed description is not provided herein.
