Background
In clinical medicine, because the skin flap has blood supply and contains skin tissues, the skin flap transplantation operation is widely applied to wound repair of patients, and the appearance and the physiological function of a receiving area are recovered. However, vascular crisis complications after flap transplantation are likely to occur, leading to the risk of re-transplantation and even amputation for the patient. Therefore, generally, within 7 days after the skin flap transplantation by a doctor, a nurse is required to carry out intensive skin flap microcirculation observation and disease condition reporting on a skin flap receiving area, timely discover the change of the transplanted skin flap and take effective measures to ensure that a patient safely passes through the critical period of blood vessel crisis complications after the skin flap transplantation operation.
However, due to the high observation frequency and the need for observing frequency change during the observation period (e.g. 72 hours before operation, 1 hour/time after operation, 96 hours after operation, 4 hours/time after operation), a nurse is required to observe, measure, shoot, record and warn the skin flap transplanted on the patient in time so that the doctor can know the postoperative condition of the transplanted skin flap through the shot pictures or videos in time. The doctor gives the nurse treatment measure feedback in time under the reference of the picture or video shot and recorded by the nurse and the record of the measurement parameter, or further observes and tests on site under the picture video early warning, and makes appropriate condition improvement or blood vessel crisis treatment measures. The nurse observes the transplanted skin flap of the patient, shoots and records early warning, and shooting and measuring records are not standard and uniform, such as shooting light rays, angles or distances are different every time, so that the nurse early warning judgment and the doctor diagnosis judgment are affected seriously; sometimes, the patients are numerous, the nursing work is heavy, and the condition of the patient cannot be timely and effectively discovered due to untimely observation or omission of nurses; the early warning records are lack of unity and perfection, which affects the unity comparison of early warning and diagnosis, increases the misdiagnosis probability in serious cases and delays the treatment time of the illness state.

Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.
Referring to fig. 1, an embodiment of the present application provides a flap monitoring system 100, and the flap monitoring system 100 may include a first terminal 101, a second terminal 102, and a server 103. The first terminal 101 and the second terminal 102 can perform data interaction with the server 103, so that the first terminal 101 and the second terminal 102 can cooperate with the server 103 to execute a flap image acquisition method (the first terminal 101 and the second terminal 102 may be the same device or different devices). In this embodiment, a mobile phone used by a nurse for the first shooting is taken as an example of the first terminal 101, and a mobile phone used by a nurse for which subsequent shooting is required is taken as an example of the second terminal 102, which will be described in detail.
Illustratively, a doctor can use a terminal with a photographing function, such as a mobile phone (for the sake of distinction, the terminal used by the doctor is referred to as a doctor terminal in this embodiment), take an image containing a transplanted flap of a patient and add a label to the taken image, thereby obtaining a labeled image. The doctor terminal may transmit the image with the tag added thereto to a terminal used by a nurse, for example, a mobile phone through the server 103 (for convenience of distinction, the terminal used by the nurse is referred to as the first terminal 101 in this embodiment), or the doctor terminal may directly transmit the image with the tag added thereto to the first terminal 101. The nurse may refer to the tagged image displayed on the first terminal 101, perform a first photographing using the transplanted flap bandaged after the operation of the patient with the first terminal 101, and mark a corresponding positioning mark at a physical mark of the transplanted flap in the photographed image, thereby adding the positioning mark to the image (for the convenience of distinction, the image with the positioning mark is referred to as a first image in this embodiment). The first image is sent to the server 103 by the nurse through the first terminal 101 for processing, so as to generate a shooting mark (the position of the shooting mark in the shooting interface is consistent with the position of the positioning mark in the first image) in a shooting interface of a terminal (for the convenience of distinguishing, the terminal used by the nurse for subsequent shooting is called a second terminal 102) used by the nurse for subsequent shooting (shooting after the nurse first-time shooting), so that the nurse for subsequent shooting can shoot a second image containing a skin flap wrapped by a patient with the aid of the shooting mark, and the first shooting of the nurse is used as a target bar and a reference for subsequent shooting.
It should be noted that the number of the first terminal 101, the second terminal 102 and the server 103 is not limited to the number shown in fig. 1, and the number of the first terminal 101, the second terminal 102 and/or the server 103 may be actually multiple, for example, 10, 20, etc.
Referring to fig. 2, fig. 2 provides a block diagram of an electronic device 10. In this embodiment, when the electronic device is a terminal device (e.g., the first terminal 101 and the second terminal 102), the electronic device may be a smart phone, a tablet computer, a personal computer, or the like. At this time, the electronic apparatus 10 may include a communication interface 12 to which a camera assembly 15 is connected via a network, one or more processors 14 for executing program instructions, a bus 13, and a different form of memory 11, such as a magnetic disk, ROM, or RAM, or any combination thereof.
Illustratively, the memory 11 stores a program. The processor 14 can call and run the programs from the memory 11 so that the skin flap image acquisition method can be executed by running the programs, and the processor 14 completes the execution of the skin flap image acquisition method by the execution of the skin flap image acquisition method.
When the electronic device 10 is the server 103, the server 103 may be a web server, a database server, a cloud server, a server assembly composed of a plurality of sub servers, or the like. And when the electronic device is the server 103, the camera assembly 15 may not be included. For the rest of the structure, reference is made to the above description of the structure of the electronic device 10, which is not described here in detail.
In the present embodiment, the skin flap image acquiring method can be executed by cooperation of each electronic device in the skin flap monitoring system 100, and the flow of each step of the skin flap image acquiring method will be described in detail below with reference to the drawings.
Referring to the flowchart of the method for obtaining a skin flap image shown in fig. 3, in this embodiment, the method for obtaining a skin flap image may include: step S10 and step S20.
Step S10: a first image of a graft flap is acquired, wherein the first image is labeled with a positioning marker corresponding to a physical marker on the graft flap.
Step S20: and determining the position of the positioning mark in the first image, and determining a shooting mark in a shooting interface of the terminal according to the position, wherein the position is consistent with the position of the shooting mark in the shooting interface.
In this embodiment, before the operation of step S10, an example is described to facilitate understanding of the method.
The flap monitoring system 100 can cooperate with clients running on the first terminal 101 and the second terminal 102 through the server 103 to realize the function of the flap image acquisition method.
At least two user identities may be included on the client: the doctor and the nurse in the present embodiment will be described with reference to the practical application scenario, that is, the doctor uses the mobile terminal and the nurse uses the first terminal 101 and the second terminal 102 to describe the scenario in the present embodiment. Of course, the two user identities of the doctor and the nurse are illustrated here, and are not limited to these two identities, and in some possible embodiments, the client may also include identities of the principal, the patient, and the like, and is not limited here.
After the patient is admitted, a nurse can enter information of the patient through a client on the first terminal 101 or the second terminal 102 (the first terminal 101 and the second terminal 102 can independently store the entered information of the patient through synchronization), such as name, sex, department, hospital number, nurse's unique ID (Identity document, identification number, and nurse's unique ID can correspond to the nurse's name), date of admission, doctor, operation name, operation time and other information, and after the patient information is entered, the patient information can be supplemented and modified subsequently to ensure the accuracy of the patient information. After the patient information is entered, the patient information can be displayed in an added patient list of the client, and for the patient with incomplete information entry, the patient information can be displayed in a patient list to be completed, so that the subsequent completion is facilitated. In the added patient list, the patient can be sorted according to the patient bed number, so that the management is convenient. Of course, other ordering may be used, such as the patient initials, or the time at which patient information entry is complete, the time of entry, etc., and is not limited herein.
Before a patient performs a skin flap operation, a doctor can shoot a skin flap supply area of the patient to obtain a supply area skin flap image; and after the skin flap operation is completed, the doctor can draw a physical mark convenient for observation and positioning shooting on the skin flap of the affected area, for example, the physical mark can comprise a cross ring and a cross, the cross ring is a mark for penetrating a fulcrum, and the cross is a mark for positioning shooting, wherein the cross can be drawn near the far end of the vascular pedicle or in a blank place which is not covered by gauze on the transplanted skin flap). When physical marks are made on skin flaps, the marks can be made with pens which do not fade easily or are alcohol washed off. After the marking is finished, the doctor can use the doctor terminal to take the whole shot of the marked transplanted skin flap so as to obtain the image shot by the doctor terminal and further improve the information of the patient subsequently.
It should be noted that, for the part of the transplanted flap that may be wrapped by the gauze later, the doctor may draw the physical mark on the exposed part to avoid the situation that the physical mark drawn by the doctor cannot be observed and photographed at the later stage due to being wrapped by the gauze.
The reason why the puncture point and the far end of the vascular pedicle are marked is that vascular crisis is most likely to occur at the two positions in the actual nursing process after the skin flap transplantation operation, and the positions can be marked, so that the positions can be intensively observed in the subsequent nursing and observing processes, and the occurrence of the vascular crisis is prevented as much as possible.
Then, the doctor can use the doctor terminal to complete the operation information of the patient, such as operation specific time, flap supply area information and flap reception area information, for example, the operation time can be 12 months and 25 days in 2018: 00-14: 00, the supply area is the front side of the left thigh, and the receiving area is the front side of the right leg. And, the doctor can modify the name of the operation to ensure the correctness of the name of the operation, for example, modify the name of the operation to the operation of the superior ulnar collateral branch flap.
In this embodiment, the doctor may directly upload the delivery area image to the server 103 using the doctor terminal. The uploaded donor area image may be images of a plurality of donor areas, for example, a donor area skin flap image on the front side of the left thigh, and a donor area skin flap image on the inner side of the left thigh, which is not limited herein.
In this embodiment, the doctor may add a tag to an image captured by the doctor terminal and upload the tagged image. For example, the doctor may add corresponding labels to the near end and near end of the blood vessel pedicle in the image taken by the doctor terminal, for example, add a label to the near end of the blood vessel pedicle to mark the near end of the blood vessel pedicle in the image taken by the doctor terminal; and adding a vessel pedicle distal end label at the vessel pedicle distal end in the image shot by the doctor terminal to mark the vessel pedicle distal end.
For example, the donor skin flap image P1 uploaded by the doctor is shown in fig. 4, which is the front side of the right thigh of the patient in fig. 4, and the donor skin flap is from the front side of the left thigh of the patient.
And fig. 5 shows the marks A1 and B1 made by the doctor on the transplanted flap after the flap transplantation operation is completed, wherein A1 is the mark for positioning shooting and B1 is the mark for penetrating the fulcrum.
As shown in fig. 6, the labeled image P2 uploaded by the doctor adds markers for the proximal end and distal end of the vascular pedicle to the image captured by the doctor's terminal, and obtains a labeled image P2. Where A2 and B2 are markers added to the image by the physician, A2 is a label indicating the distal end of the vascular pedicle over the graft flap, and B2 is a label indicating the proximal end of the vascular pedicle over the graft flap.
In this embodiment, for some special cases, for example, a plurality of physical marks are on a transplanted skin flap, the doctor marks a plurality of labels on the image shot by the doctor terminal. After the skin flap transplantation operation, the cross ring for indicating the pivot and the cross for positioning can not appear on the same picture, a plurality of images can be correspondingly shot for the cross ring and the cross at each position, then corresponding labels are added to all the near ends and far ends of the vascular pedicle in the plurality of images, and the images added with the labels are uploaded.
After the doctor uploads the skin flap image and the image added with the label, the doctor can check and modify the uploaded image so as to ensure the accuracy of the patient information.
The doctor may upload the tagged image to the server 103 through the doctor terminal and forward it to the first terminal 101 of the nurse by the server 103, or the doctor terminal may directly transmit the tagged image to the first terminal 101. When a nurse uses the first terminal 101 to shoot a transplanted skin flap of a postoperative patient for the first time, the nurse can refer to the image which is displayed on the first terminal 101 and added with a label, and carry out careful shooting on the transplanted skin flap of the postoperative patient for the first time to obtain an image shot by the first terminal 101.
Unlike the doctor imaging, the doctor imaging may be imaging of the entire graft skin flap, and the nurse imaging may be imaging of the details of the graft skin flap.
Then, the nurse may add a positioning mark through the fulcrum or at the distal end of the vascular pedicle in the image taken by the first terminal 101, thereby obtaining a first image.
For example, if the first terminal 101 can capture the puncture point and the far end of the vascular pedicle in one shot, the nurse can select a cross ring or a cross in the image captured by the first terminal 101 to add a positioning mark according to the dressing condition of the transplanted skin flap. For example, when gauze covers a cross circle at the puncture point, but does not cover a cross near the distal end of the vascular pedicle, a positioning mark may be added at the cross in the image taken by the first terminal 101; alternatively, when the gauze covers the cross near the distal end of the vascular pedicle but does not cover the cross circle at the branch puncture point, a positioning mark may be added at the cross circle in the image captured by the first terminal 101; alternatively, when neither the cross-loop at the puncture point nor the cross at the distal end of the vascular pedicle is covered with gauze, a positioning mark may be added at an optional one of the cross and the cross-loop in the image taken by the first terminal 101 (it is generally selected to add a positioning mark at the cross-loop).
If the first terminal 101 can only shoot the puncture point or the far end of the vascular pedicle in each shooting and needs to shoot the puncture point or the far end of the vascular pedicle for multiple times, the nurse can add a positioning mark to the image shot by the first terminal 101 every time. For example, if the puncture point is on the back of the patient's foot and the vascular pedicle distal end is on the sole of the patient's foot, the first terminal 101 needs to be photographed in two times. The first terminal 101 first takes an image containing a penetrating point, and a nurse can add a positioning mark to a cross ring in the image containing the penetrating point; the first terminal 101 again takes an image containing the distal end of the vessel pedicle and the nurse may add a positioning marker at the cross in the image containing the distal end of the vessel pedicle. For example, as shown in fig. 7 and 8, the nurse adds a cross mark to the first-taken post-operative image of the transplanted flap. Where figure 7 shows a nurse's mark applied at the cross near the distal end of the vascular pedicle when the cross-loop at the point of debranching is covered with gauze. Fig. 8 shows a cross marker C2 (location marker) added by the nurse at the cross-loop at the puncture site when the cross at the distal end of the vessel pedicle is covered with gauze.
It should be noted that fig. 7 shows only one cross since the center point of the cross mark C1 added to fig. 7 coincides with the center point of the cross circle. The center point of the cross marker C2 added in fig. 8 coincides with the center point of the cross at the distal end of the vascular pedicle, so only one cross is shown in fig. 8.
After the first terminal 101 obtains the first image, the first terminal 101 may upload the first image to the server 103, and then the server 103 may perform step S10.
Step S10: a first image of a graft flap is acquired, wherein the first image is labeled with a positioning marker corresponding to a physical marker on the graft flap.
In this embodiment, the nurse uploads the first image to the server 103 through the first terminal 101, and the server 103 acquires the first image accordingly, and continues to execute step S20.
Step S20: and determining the position of the positioning mark in the first image, and determining a shooting mark in a shooting interface of the terminal according to the position, wherein the position is consistent with the position of the shooting mark in the shooting interface.
In this embodiment, in order to determine the position of the positioning mark in the first image, the server 103 may perform binarization processing on the first image to determine a binary image of the first image. After obtaining the binary image of the first image, the server 103 may detect the positioning mark in the binary image.
For example, the server 103 may detect a circle of a cross or a location mark added at the cross in the binary image. After detecting the positioning mark in the binary image, the server 103 may determine the position of the positioning mark in the binary image, thereby obtaining the position of the positioning mark in the first image. In this way the position of the positioning marker in the first image is determined, simply and accurately.
It should be noted that, in this embodiment, one or more positioning marks may be provided, for example, two, four, etc., and the number of the positioning marks is not to be considered as a limitation to the present application.
After the server 103 determines the position of the positioning mark in the first image, a shooting interface of the second terminal 102 is preset in the server 103, so that the server 103 can determine a shooting mark in the shooting interface, which is consistent with the position of the positioning mark in the first image, according to the position of the positioning mark in the first image.
As an exemplary way of determining the photographing mark, the position of the subsequently photographed second image needs to be as identical as possible to the position of the first image photographed so that the subsequently photographed second image of the nurse highly coincides with the first image photographed by the nurse for the first time. Then, the server 103 may determine a difference between the first image and the shooting interface according to the size of the first image and the size of the shooting interface of the second terminal 102. For example, if the size of the first image is 100 × 160 and the size of the capture interface of the second terminal is 80 × 120, then determining the difference between the first image and the capture interface can be done by calculating the ratio between the size of the first image and the size of the capture interface of the second terminal, the ratio resulting in: 0.8*0.75. Of course, the way of calculating the difference here is one of the ways, and the difference between the size of the first image and the size of the shooting interface of the second terminal may also be calculated by calculating the difference, and is not limited here.
The server 103 can flexibly adjust the position of the shooting mark in the shooting interface according to the difference by calculating the difference between the size of the first image and the size of the shooting interface of the second terminal and combining the position of the positioning mark in the first image, so that the flap image acquisition method can be applied to terminals with different shooting interfaces.
After the server 103 determines the shooting mark in the shooting interface, the server 103 may send the shooting mark to the second terminal 102, so that the second terminal 102 can generate the shooting mark at a corresponding position in the self-shooting interface.
Of course, the determination of the shooting mark is not limited to be determined by the server 103, and in other exemplary manners, after the server 103 determines the position of the positioning mark in the first image, the server 103 may feed back the determined position to the second terminal 102, so that the second terminal 102 can generate the shooting mark at the corresponding position in the self-shooting interface according to the position. Or the shooting mark can be added in the shooting interface by the nurse, so that the situation that some generated shooting marks are not suitable in position can be avoided, the standard degree of the shot second image is improved, and the doctor can observe the shot second image conveniently.
In this embodiment, the shooting mark generated by the second terminal 102 can facilitate the nurse to use the second terminal 102 to continue shooting the transplanted skin flap of the postoperative patient, so that the position of the transplanted skin flap in the shot second image is consistent with the position of the transplanted skin flap in the first image (i.e. the second image is highly consistent with the first image).
The first terminal 101 and/or the second terminal 102 will be described in detail below with reference to photographing of the graft skin flap.
After a flap-grafting procedure, it is usually necessary to perform high-frequency observation of the transplanted flap of the patient within one week, for example, the first 72 hours, 1 hour/time; after 96 hours, 4 hours/time, to find the bad condition as early as possible. Of course, the situation here is based on the actual situation, for example, the vascular crisis of the transplanted flap of some patients needs to be readjusted to 1 hour/time no matter which frequency observation interval is currently.
The nurse may view the patient's information through the client on the second terminal 102, and the patients who need the nurse to view may be presented through the list. Illustratively, patients may be displayed in categories based on frequency of observation, e.g., patients with an observation frequency of 1 hour/time in one list and patients with an observation frequency of 4 hours/time in another list. The patient information of show can show patient's name and last observation world to the nurse in time observes, shoots the image and the record.
After the nurse takes the first post-operative observation of the patient, the nurse needs to continue to take the continuous observation of the patient. Patient information may be selected to determine the identity of the patient as the nurse continues to take observations of the patient. After the patient identity is determined, the nurse may use the client on the second terminal 102 to photograph the patient's graft flap.
For example, when the observation photographing is continued for the patient, the nurse may select one of two modes, i.e., a standardized photographing (in which the photographing mark is displayed in the photographing interface) and a non-standardized photographing (in which the photographing mark is not displayed in the photographing interface). The method is suitable for observation of transplanted skin flaps after small skin flap surgeries for non-standardized shooting, has no strict requirements on shooting positions when pictures are shot, and needs to enable shooting distances, shooting angles and light rays to be the same as those of the first shooting as far as possible. For standardized shooting, strict requirements are imposed on the shooting position when the picture is shot, so that the shot second image can effectively reflect the condition of the transplanted skin flap of the patient and is convenient for doctors to observe, diagnose and the like.
Before the nurse selects the standardized shooting, the second terminal 102 can display the first image shot before, so that the nurse can know the approximate shooting position of the transplanted skin flap needing to be shot, and the efficiency of the nurse is improved. After the nurse selects the standardized photographing, the second terminal 102 may generate a photographing mark in the photographing interface according to the position of the positioning mark in the first image, the photographing mark corresponding to the position of the positioning mark in the first image. Because the transplanted skin flap of the patient has the mark made by the doctor with the pen, the shooting can be performed after the shooting mark on the shooting interface is aligned with the mark on the transplanted skin flap, so that the camera position of the second image is consistent with the camera position of the first image (consistency does not mean that the camera position of the second image is completely the same as the camera position of the first image, and the camera position slightly different from the camera position can also be understood as consistency). Because the camera positions are consistent, the shot second image can be conveniently observed by a doctor, important observation information cannot be omitted in the shot second image due to negligence of a nurse, and the efficiency of observing the transplanted skin flap of the patient by the doctor and the nurse is favorably improved.
For example, as shown in fig. 9, there are shooting marks (cross marks for locating the puncture point) in the shooting interface, and the nurse can complete the shooting by adjusting the shooting position to align the cross mark in the shooting marks with the physical mark W1 (cross circle) at the puncture point on the transplanted flap, and the second image P4 is shown in fig. 10.
In addition, during the standardized shooting process by the nurse, the second terminal 102 may further detect a physical mark on the transplanted skin flap in the shooting interface, and for example, the second terminal 102 may identify the physical mark in the shooting interface through a pre-machine learning pair (that is, the second terminal 102 may identify whether a cross or a cross circle exists in the shooting interface), and determine a current position of the physical mark on the transplanted skin flap in the shooting interface of the second terminal (the current position may dynamically change according to a change of the position of the second terminal 102).
After the second terminal 102 determines the current position of the physical mark on the transplanted flap in the shooting interface of the second terminal, the second terminal 102 may further determine a position difference between the current position and the position of the shooting mark in the shooting interface, and determine whether the position difference is smaller than a preset position difference threshold.
If the position difference is smaller than a preset position difference threshold (the position difference is smaller than the preset position difference threshold and indicates that the current position of the physical mark is almost coincident with or already coincident with the position of the shooting mark), the second terminal 102 may generate and display a prompt message in the shooting interface, where the prompt message is used to prompt a nurse that the second terminal 102 may be currently controlled to shoot. Correspondingly, the nurse controls the second terminal 102 to take a picture based on the instruction of the prompt message, and obtains a second image. Of course, when the position difference is smaller than the preset position difference threshold, the second terminal 102 may also automatically shoot, so that it is more convenient to shoot the second image.
When the position difference is not less than the preset position difference threshold, the second terminal 102 may convert the moving direction and the moving distance of the machine position of the second terminal 102 on the focal plane according to the position difference, and generate and display a prompt message in the shooting interface according to the moving direction and the moving distance, where the displayed prompt message may be used to prompt a nurse how to adjust the machine position, for example, the content of the prompt message may be to please move the machine position horizontally leftward by XX distance or horizontally upward by XX distance, and the like.
In addition, in this embodiment, the second terminal 102 may further determine a shooting distance between the machine position of the second terminal 102 and the physical mark on the transplanted skin flap to be shot according to the size of the physical mark on the transplanted skin flap detected on the shooting interface, and determine whether the shooting distance is consistent with a distance preset in the second terminal 102. When it is determined that the shooting distance is inconsistent with the preset distance, the second terminal 102 may generate a prompt message for prompting a nurse to adjust the shooting distance. When it is determined that the photographing distance is inconsistent with the preset distance, the second terminal 102 may prompt the nurse that the second terminal 102 may be currently controlled to perform photographing or automatic photographing.
It should be noted that, in this embodiment, the determination of the shooting distance and the machine position may be performed simultaneously, and when both meet the requirements, automatic shooting may be performed or shooting prompt information may be generated to prompt a nurse to shoot to capture a second image, which is not limited herein.
Of course, after the shooting interface has the shooting mark, the nurse may shoot the transplanted skin flap by aligning the shooting mark with the shooting nurse, and in some cases of detecting the inaccurate mark on the transplanted skin flap, the nurse may shoot the second image by aligning the shooting nurse manually, which is not limited herein.
In this embodiment, in order to make the captured second image as consistent as possible with the first image in terms of brightness of light, a dimming function may be provided for the nurse to dim in the capturing interface, so that the captured second image is as consistent as possible in terms of brightness and tone with the first image, which is convenient for the doctor to observe and compare.
It should be noted that, in this embodiment, the number of the shot marks may be one, that is, it is determined that only one shot mark is used in each shot, and for the plurality of marks on the transplanted flap, a specific mark type may be detected, for example, only the physical mark (cross circle) at the perforator, or only the physical mark (cross) at the distal end of the vascular pedicle is detected, or the physical mark (cross circle) at the perforator is preferentially detected, and then the physical mark (cross) at the distal end of the vascular pedicle is detected, which is not limited herein, and may be reasonably agreed according to actual conditions, so as to make the method more practical.
It should be noted that the shooting process described above may also be executed by the server 103. For example, the second terminal 102 may upload a picture in the shooting interface to the server 103 in real time, and the server detects whether the current position of the physical marker in the picture is consistent with the position of the shooting marker, and sends a prompt message to the second terminal 102.
The nurse may then enter a record of observations of the transplanted skin flap through the second terminal 102. Illustratively, the nurse may manually input the color parameter and the swelling degree parameter of the graft skin flap into the second terminal 102 based on the graft skin flap in the second image.
Specifically, the nurse may adjust the color in the color chart by transplanting the color of the skin flap in the second image, until the nurse confirms that the color in the color chart is adjusted to be similar to or the same as the color of the skin flap transplanted in the second image. Correspondingly, the second terminal 102 determines the color parameter in the current color comparison card in response to the operation of confirming the end by the nurse, wherein the color parameter in the current color comparison card is the color parameter of the transplanted flap.
For example, when the nurse first draws color, the pointer of the color chart may be at the default position of normal color, and the bottom color of the screen displays the color of the position where the pointer of the color chart is drawn. The nurse can move the pointer of the color chart to adjust the color of the color chart according to the color of the transplanted skin flap in the second image. The end is confirmed when the color in the color chart is adjusted to be similar or identical to the color of the transplanted flap in the second image. The second terminal 102 may determine the name of the color, such as normal color, light red, dark red, light purple, black purple, and the like, according to which preset parameter threshold the parameter of the color in the current color card is in when the user confirms that the color is finished. If the color is not taken for the first time, the pointer can stay at the position of the last color taking.
Currently, the color sampling manner is an exemplary manner of the present embodiment, and is not limited to the present embodiment. For example, the second terminal 102 may also adopt an intelligent color-taking manner, that is, the second terminal 102 may automatically recognize the color parameter of the transplanted flap in the second image, automatically select the same or similar color parameter from the color comparison card, and perform an early warning according to a difference between the color parameter of the transplanted flap in the second image and the color parameter selected from the color comparison card.
And, the nurse may manually enter the degree of swelling parameter of the skin flap into the second terminal 102 according to the degree of swelling parameter of the transplanted skin flap in the second image. For example, the swelling/dermatoglyph condition can be recorded to determine whether the transplanted flap is normal, swollen, or swollen.
In this embodiment, the nurse may also manually enter the physiological parameters of the flap measured by the instrument, such as the temperature of the transplanted flap, the capillary reflux rate and the blood oxygen saturation, all or some of which are entered into the second terminal 102 according to actual needs.
Of course, the manner in which the second terminal 102 obtains the color parameter and the swelling degree parameter of the transplanted skin flap is not limited to the manner in which the nurse manually inputs the parameters. For example, a deep neural network preset in the second terminal 102 may be trained and verified through a training set and a verification set composed of images of various transplanted skin flaps, so as to obtain a transplanted skin flap recognition model. In this way, the second terminal 102 can directly identify the second image through the graft flap recognition model, thereby determining the color parameter and the swelling parameter of the graft flap in the second image.
Further, the second terminal 102 can compare the parameters with preset physiological parameters to determine the physiological parameter status, so that the nurse can know the skin flap more clearly by combining the parameters. For example, the temperature of the transplanted flap may be normal (normal temperature), increased (higher than normal temperature), decreased (lower than normal temperature), and the like, without limitation. The capillary blood vessel reflux speed of the transplanted skin flap can be accelerated, normal, slowed down and the like. The oxygen saturation level entered by the nurse may be a percentage parameter value or may be compared to a normal value to determine if it is a normal level. From this, the physiological parameter status can be determined. Of course, the physiological parameter status may be directly determined and recorded by a nurse, which is not limited herein.
The nurse can decide whether to mark the patient as a vascular crisis early-warning patient or not according to the physiological parameter states. Or, if any one of the physiological parameter states is an abnormal state, the patient can be automatically marked as a blood vessel crisis early-warning patient.
And after the second terminal 102 captures the second image, the second terminal 102 may upload the second image to the server 103. In this way, the server 103 can determine the degree of difference between the transplanted skin flap in the first image and the transplanted skin flap in the second image by comparing the first image and the second image, so as to reflect the change of the degree of swelling of the transplanted skin flap by the degree of difference.
In this embodiment, since the transplanted flap has fine skin lines, and the tightness of the skin lines can reflect the swelling degree of the skin, the server 103 can determine the difference of the skin lines on the transplanted flap, and then reflect the change of the swelling degree of the transplanted flap through the difference of the skin lines.
Specifically, the server 103 may determine a second distribution result of the skin texture on the transplanted flap in the second image from the binarized second image by performing binarization processing on the second image. The server 103 may compare the determined second distribution result with the first distribution result to determine the difference therebetween, where the first distribution result may be obtained by performing a process similar to the second image on the first image, and the process of obtaining the first distribution result in the first image may be performed before or in synchronization with the determination of the second distribution result.
If the skin of the graft flap swells, the lines on the skin within the contour of the graft flap change due to the swelling of the skin, e.g., the lines decrease or even disappear. In this way, it is then possible to determine whether the patient's graft flap in the second image is swollen. If the degree of difference between the second distribution result and the first distribution result exceeds the preset degree of difference, it may be that the skin of the transplanted flap is swollen, so that the warning message may be generated and sent to the second terminal 102. Thus, the nurse can know that the skin flap difference degree exceeds the preset difference degree according to the early warning information displayed by the second terminal 102, and mark the label of the patient in the second terminal 102 as the blood vessel crisis early warning patient.
By means of the comparison mode, when swelling of the transplanted skin flap of the patient occurs, a nurse can be reminded that the transplanted skin flap changes and is abnormal, and the condition that swelling is not found due to carelessness or fatigue of the nurse can be avoided as much as possible. Therefore, the medical staff can be assisted in observing the transplanted skin flap of the patient.
It should be noted that the execution flow of determining the second distribution result and the first distribution result and comparing the second distribution result and the first distribution result is not limited to be executed by the server 103, and may also be executed by the first terminal 101 or the second terminal 102.
In this embodiment, for some special cases, the nurse may also record the capillary reflux test video at the transplanted flap through the second terminal 102 and upload the video to the server 103 to help the doctor understand the condition of the transplanted flap of the patient, thereby helping the doctor make an accurate diagnosis.
In addition, after the nurse inputs the observation information of the patient to the server 103, the nurse can select whether to mark the patient as a blood vessel crisis early warning patient or not, and can leave a message for the doctor of the patient to introduce detailed conditions, which is helpful for the doctor to quickly know the condition of the transplanted skin flap of the patient. In this embodiment, after the nurse marks the critical blood vessel condition early warning patient, the server 103 may send a prompt message to the doctor terminal to prompt the doctor to handle as soon as possible.
After the nurse inputs the observation information of the patient, the nurse can start to observe the patient with the next observation time and input the observation information.
After the nurse submits the observation information of the patient, the doctor terminal which can be used by the doctor checks the observation information, the messages of the nurse and the like. For the blood vessel crisis early-warning patient marked by the nurse, the doctor can judge the condition of the patient by combining the observation information input by the nurse, sometimes the doctor can also judge by himself at the bedside of the patient and input the judged information. And the doctor can also modify the wrong information input by the nurse based on the observation of the second image, so that the accuracy of the patient information is ensured. The doctor can also enter orders to explain the situation, notice and the like, which is not limited herein.
In this embodiment, the physician can make a diagnosis of a patient who has been nursed as a pre-warning patient of vascular crisis. For example, if the diagnosis is normal, the doctor can enter the diagnosis result and the order; if the diagnosis is a vascular crisis, a doctor can immediately prepare and take corresponding measures so as to treat the patient in time; for patients diagnosed with vascular crisis, the doctor can enter the results and medical orders to inform the nurse to pay attention to observe. Of course, these are merely examples and should not be construed as limiting the present application.
In this embodiment, if the doctor fails to deal with the skin flap in time, other doctors may use another terminal to perform diagnosis or order entry, so that the nurse can clearly know the condition of the skin flap transplanted to the patient and perform corresponding observation.
By the mode, doctors and nurses can know the condition of the patient clearly and timely as far as possible, and information between the doctors and the nurses can be kept smooth, so that the nursing efficiency of the doctors and the nurses to the patient after the skin flap transplantation operation can be greatly improved, and the time of a plurality of doctors and nurses can be saved.
After the doctor diagnoses the blood vessel crisis early-warning patient, the nurse can view the diagnosis information of the doctor from the client of the second terminal 102, and perform subsequent observation or treatment on the patient according to the doctor's order. In this example, generally, patients after skin flap transplantation surgery require 1 observation every 1 hour by a nurse for the first 72 hours, and 1 observation every 4 hours thereafter for 96 hours. In practical situations, if the patient is marked as a blood vessel crisis early-warning patient, the doctor can adjust the observation time of 1 hour every 4 hours back to the observation time of 1 hour every 1 hour at the doctor terminal or the nurse at the second terminal 102, and continue the observation for 24 hours. If no improvement occurs after 24 hours, the observation is ended and the operation is performed again. It can be understood that since doctors and nurses can change the observation time, the method has stronger flexibility and can adapt to the actual complex postoperative condition.
In this embodiment, in the list of the patients that the nurse needs to observe, the nurse fails to observe and enter the observation information in time, the client of the second terminal 102 may mark the name of the patient as a striking state to prompt the nurse to observe in time, the nurse does not enter the observation information even if the time elapses, and the nurse may be prompted once every other period, for example, once every 15 minutes, and the nurse is prompted to observe and enter the observation information as soon as possible for the patient.
Through the mode, the observation of the transplanted skin flap of the patient can be avoided as far as possible from being missed by a nurse, so that the observation efficiency and the nursing quality of the patient after the skin flap transplantation operation are improved.
In the present embodiment, when there is no abnormal situation in the patient, the nurse may end the observation of the patient after completing the observation for a total of 168 hours; for the patients with abnormal conditions, when no abnormal conditions occur in the observation which lasts for a period of time after the patients are recovered to be normal, the observation of the patients can be ended; and, at any time, after the doctor wraps the patient's graft flap, the nurse can manually end the observation. Of course, this is by way of example only and not by way of limitation.
After the observation of the patient is finished, the server 103 archives all records of patient information, observation information and the like of the patient, and then, doctors, nurses or other doctors and nurses check the information of the patient through the terminal used by the doctors, nurses or other nurses, but the information cannot be modified any more, so that the accuracy of the patient information is ensured.
The observation of the transplanted flap operation patient is realized by the flap image acquisition method, and the problems of untimely clinical early warning, irregular and inaccurate recorded data, disordered corresponding patient, missed diagnosis, misdiagnosis and the like can be avoided as much as possible.
