[0014] Figure 2 is a module flow chart of a wound care device control method. DETAILED DESCRIPTION
[0015] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-Figure 2It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0016] The embodiments of the present application are further described in detail below in conjunction with the drawings in the specification.
[0017] The present application embodiment discloses a wound care device control method, referring to Figure 1 The method flow of the wound care device control method includes the following steps: Step S100: obtaining the surface detection pressure of a pressure collection device preset on the wound surface and the wound generation time point.
[0018] The pressure collection device is a device that can detect the pressure on the wound surface. For example, a strain gauge pressure sensor is made into a thin sheet and attached between the wound dressing and the skin. The sensor is connected to a signal collection device to record and display pressure data in real time. The surface detection pressure is the value obtained by the pressure collection device, and the time point of wound formation is the time point when the operation ends, which is manually input by the nursing staff according to the specific surgical situation.
[0019] Step S101: construct a recovery interval according to the wound formation time point and the current time point, and divide the recovery interval into healing intervals of different healing periods according to a preset recovery rule, and define the healing period corresponding to the healing interval at the current time point as the latest period.
[0020] The recovery interval refers to the time interval with the wound formation time point as the front end point and the current time point as the back end point. The recovery rules are the rules for wound recovery set in advance, for example, 0-A is the inflammatory period, AB is the proliferative period, and BC is the remodeling period. The specific recovery rules are determined by nursing staff according to different wound surgeries; the healing interval refers to the time interval corresponding to different healing periods. The latest period is defined to mark the recovery time interval of the current wound for subsequent analysis.
[0021] Step S102: Determine the effective recovery pressure range corresponding to the latest period according to the preset recovery matching relationship.
[0022] The effective recovery pressure range is the range of pressure that the wound needs to be subjected to in order to recover well in the current latest period. Different latest periods correspond to different effective recovery pressure ranges. The recovery matching relationship between the two is determined by the staff through multiple tests in advance.
[0023] Step S103: determining whether the surface detection pressure is within the effective recovery pressure range.
[0024] The purpose of judgment is to know whether the current wound can heal well.
[0025] Step S1031: If the surface detection pressure is within the effective recovery pressure range, the original state is maintained.
[0026] When the surface detection pressure is within the effective recovery pressure range, it means that the current pressure on the wound is conducive to healing. At this time, the original state can be maintained without additional control.
[0027] Step S1032: If the surface detection pressure is not within the effective recovery pressure range, then determine the effective required pressure within the effective recovery pressure range.
[0028] When the surface detection pressure is not within the effective recovery pressure range, it means that the current pressure on the wound cannot achieve a good healing effect, so further analysis is needed; the effective demand pressure is the pressure value that the wound surface needs to reach to facilitate wound healing, which can be determined by randomly selecting a pressure value in the effective recovery pressure range, or by referring to the method of steps S400-S406.
[0029] Step S104: Calculate and determine the required adjustment pressure according to the effective required pressure and the surface detection pressure, and control the adjustment device preset on the wound surface and connected to the compression belt to perform tightness adjustment according to the required adjustment pressure.
[0030] The demand adjustment pressure is the difference between the effective demand pressure and the surface detection pressure, that is, the pressure value at which the tightness of the compression belt on the wound surface needs to be adjusted. The tightness of the compression belt at the wound can be adjusted by operating the adjustment device, so that the pressure on the wound meets the demand; wherein the adjustment device is a device that can drive the compression belt to adjust the tightness, such as a device composed of a motor and a transmission device, wherein the motor receives the command of the control unit, drives the movement of the compression belt through the transmission device, thereby adjusting the tightness of the compression belt After the surface detection pressure is obtained, the wound care device control method further includes: Step S200: obtaining the pressure applied by the device.
[0031] The pressure applied by the device refers to the pressure value applied to the wound surface externally after the adjustment device is adjusted.
[0032] Step S201: Calculate the difference between the surface detection pressure and the device applied pressure to determine the actual wound pressure.
[0033] The actual wound pressure is the pressure value that the wound will actually present without external influence, which is determined by subtracting the pressure applied by the device from the surface detection pressure.
[0034] Step S202: Determine the actual reasonable pressure range corresponding to the latest period according to the preset reasonable matching relationship.
[0035] The actual reasonable pressure range is the range of actual pressures that need to be reached when the wound is healed better. Different latest periods indicate different wound healing times, and the corresponding actual reasonable pressure ranges are also different. The reasonable matching relationship between the two is determined by the staff in advance based on multiple tests.
[0036] Step S203: Determine whether the actual pressure of the wound is within an actual reasonable pressure range.
[0037] The purpose of the judgment is to know whether the wound is in a good healing state, that is, to determine whether inflammation occurs.
[0038] Step S2031: If the actual pressure of the wound is within the actual reasonable pressure range, a normal healing signal is output.
[0039] When the actual pressure of the wound is within the actual reasonable pressure range, it means that the wound is healing normally, and at this time, a normal healing signal can be output.
[0040] Step S2032: If the actual pressure of the wound is not within the actual reasonable pressure range, an abnormal healing signal is output.
[0041] When the actual pressure of the wound is not within the actual reasonable pressure range, it means that the wound is not healing in time, that is, there may be problems such as inflammation. At this time, an abnormal healing signal is output to identify the situation so that the nursing staff can be aware of the situation in time and deal with it accordingly.
[0042] After the actual pressure of the wound is obtained, the wound care device control method further includes: Step S300: constructing a unit interval with a width of a preset unit time length on a preset time axis with the current time point as the rear end point, and defining the actual wound pressure obtained at the front end point of the unit interval as the preceding actual pressure.
[0043] The time axis is a coordinate axis formed by the combination of various time points, and the coordinate axis points from the time points that have passed to the time points that have not yet arrived, wherein the time points that have passed are on the left side of the time axis, and the left side is defined as the front end of the time axis; the unit duration is a fixed duration set by the staff, and the value of the fixed duration should be small, such as 3-5 minutes, and a unit interval is constructed to facilitate the acquisition and analysis of data within the unit duration; the preceding actual pressure is defined to distinguish the actual pressure of the wound at different time points, which is convenient for subsequent analysis.
[0044] Step S301: performing a difference calculation based on the current actual wound pressure and the previous actual pressure to determine the actual change pressure.
[0045] The actual change pressure is the difference between the current actual pressure of the wound and the previous actual pressure, and the difference is an absolute value.
[0046] Step S302: Determine whether the actual change pressure is greater than the preset allowable change pressure.
[0047] The allowable change pressure is the minimum actual change pressure that needs to be met when the pressure change value set by the staff is large and there is a situation caused by the staff's posture change. The purpose of the judgment is to know whether the currently determined surface detection pressure changes significantly.
[0048] Step S3021: If the actual change pressure is not greater than the allowable change pressure, the adjustment device is controlled according to the current actual wound pressure and the surface detection pressure.
[0049] When the actual change pressure is not greater than the permitted change pressure, it indicates that the current user has not had an obvious change in posture, which means that the wound healing condition can be better detected and analyzed at this time, and normal analysis and control can be performed at this time.
[0050] Step S3022: If the actual change pressure is greater than the permissible change pressure, the subsequent situation is not controlled and analyzed based on the current actual wound pressure and the surface detection pressure.
[0051] When the actual change pressure is greater than the allowed change pressure, it means that the current user has an obvious change in posture, that is, the surface detection pressure obtained at this time cannot objectively reflect the actual situation of the wound. At this time, the obtained data is not analyzed and processed to reduce the occurrence of invalid adjustment of the adjustment device.
[0052] The steps for determining the effective demand pressure within the effective recovery pressure range include: Step S400: constructing a recording interval with the current time point as the rear end point and a width of a preset recording duration on the time axis, and defining the actual wound pressure of each user as the reference actual pressure in the recording interval.
[0053] The recording duration is a fixed duration set by the staff, which is a relatively long period of time, such as 1-3 years. By constructing a recording interval, it is convenient to obtain the data of other personnel within the recording period; define the actual control pressure to distinguish the actual pressures of different wounds, which is convenient for subsequent analysis.
[0054] Step S401: Analyze the actual wound pressure corresponding to the current user and the control actual pressure of the user in the recording interval to determine the control user.
[0055] The control users are other users whose healing effects are similar to those of the current user during the wound healing process. The specific determination method can refer to steps S500 to S503.
[0056] Step S402: defining the time point corresponding to the current time point in the control user as the starting point, and constructing a short-term interval with a width of a preset short-term duration on the time axis with the starting point as the front end point.
[0057] The starting point is the time point corresponding to the current time point in the control user, where the corresponding meaning is as follows: for example, if the current time point is the Y time point of the X healing period, then the starting point is the Y time point of the X healing period of the control user; the short-term duration is a shorter duration set by the staff, such as 3-5 hours, and the short-term interval is constructed to facilitate the prediction and processing of the subsequent wound healing situation.
[0058] Step S403: defining the control actual pressure in the short-term interval as the subsequent predicted pressure, and randomly generating a simulated demand pressure in the effective recovery pressure range.
[0059] The subsequent predicted pressure is defined to distinguish different control actual pressures. At this time, the subsequent predicted pressure is the actual pressure value predicted to appear by the current user in a short period of time after the current time point; the required pressure value is simulated by randomly generating simulated demand pressure to facilitate analysis.
[0060] Step S404: performing a difference calculation based on the simulated required pressure and the current actual wound pressure to determine the simulated applied pressure.
[0061] The simulated applied pressure is the pressure value applied to the wound surface by an external device, and is determined by subtracting the current actual wound pressure from the simulated required pressure.
[0062] Step S405: Calculate the simulated applied pressure and each subsequent predicted pressure to determine the simulated overall pressure, and count the simulated fixed number based on whether the simulated overall pressure is within the effective recovery pressure range.
[0063] The simulated overall pressure is the pressure value obtained by adding the simulated applied pressure to the subsequent predicted pressure. When the simulated overall pressure is within the effective recovery pressure range, it means that the compression belt does not need to be adjusted by the adjustment device at this time. The simulated fixed number is determined by counting the situations where no adjustment is required, which is the total number of times that no adjustment is required.
[0064] Step S406: Calculate based on the simulated fixed quantity and the preset short-term quantity to determine the simulated fixed proportion, and determine the simulated demand pressure corresponding to the simulated fixed proportion with the largest value as the effective demand pressure.
[0065] The short-term quantity is the total number of time points in which the compression belt can be adjusted within the short-term duration. The simulated fixed ratio is determined by dividing the simulated fixed quantity by the short-term quantity. The larger the simulated fixed ratio, the smaller the number of adjustments required. In other words, the simulated demand pressure determined at this time can not only meet the pressure demand, but also reduce the possibility of subsequent adjustments. Therefore, it can be defined as the effective demand pressure.
[0066] The step of analyzing the actual wound pressure corresponding to the current user and the control actual pressure of the user in the recording interval to determine the control user includes: Step S500: Calculate the difference between the user's control actual pressure in the recording interval and the actual wound pressure corresponding to the current user to determine the actual differential pressure, and define the time point when the actual differential pressure in the current user's recovery interval is less than the preset effective deviation pressure as the similarity point.
[0067] The actual differential pressure is the difference in actual pressure between two users at corresponding time points. The effective deviation pressure is the maximum actual differential pressure allowed when the pressure values of two users are relatively similar, as set by the staff. Similar points are defined to distinguish time points with relatively similar pressure values, which is convenient for subsequent analysis.
[0068] Step S501: Count similar points in each healing interval to determine the number of similar points, calculate based on the number of similar points and the preset number of interval points to determine the similarity ratio, and define the healing interval whose similarity ratio is greater than the preset requirement ratio as a similar interval.
[0069] The number of similar points is the total number of similar points in a single healing interval, and the number of interval points is the total number of time points in the healing interval that can be analyzed. Different healing intervals correspond to different numbers of interval points. The relationship between the two is determined in advance by the staff. The similarity ratio is the ratio of similar points to all time points in the healing interval, which is determined by dividing the number of similar points by the number of interval points. The required ratio is the minimum similarity ratio set by the staff to determine that the wound healing effects of two users in the corresponding intervals are similar. By defining similarity intervals to distinguish different healing intervals, it is convenient for subsequent analysis.
[0070] Step S502: Counting the healing intervals in the recovery interval to determine the overall healing number, and counting the similarity intervals to determine the interval similarity number.
[0071] The overall healing number is the total number of healing intervals determined in the recovery interval, and the interval similarity number is the total number of healing intervals that are similar intervals in the recovery interval.
[0072] Step S503: Calculate the comparison similarity according to the interval similarity number and the overall healing number, and define the user corresponding to the comparison similarity with the largest value in the recorded interval as the control user of the current user.
[0073] The comparative similarity is the ratio of the number of interval similarities divided by the total number of healings. The larger the value, the more similar the wound healing effects of the two users are. At this time, the user corresponding to the largest comparative similarity has the most similar wound healing effect to the current user, so he or she can be determined as the control user.
[0074] After the comparison similarity is determined, the wound care device control method further includes: Step S600: Determine whether there are at least two users with the same and maximum comparison similarity.
[0075] The purpose of the judgment is to find out whether there are multiple users who meet the requirements.
[0076] Step S6001: If there are not at least two users with the same and maximum comparison similarity, the user corresponding to the maximum comparison similarity is defined as the control user of the current user.
[0077] When there are not at least two users with the same and maximum comparison similarity, it means that there is only one user that meets the requirements, and in this case, the user can be determined as the control user.
[0078] Step S6002: If there are at least two users with the same and greatest comparison similarity, the user corresponding to the greatest comparison similarity is defined as a candidate user for the current user.
[0079] When there are at least two users with the same and largest comparison similarity, it means that there are multiple users that meet the requirements, so they are defined as candidate users to distinguish different users, so as to facilitate the subsequent determination of the only control user.
[0080] Step S601: Determine the interval span among candidate users according to the similar interval and the healing interval corresponding to the latest period.
[0081] The interval span is the time interval between two intervals, that is, the interval between the rear endpoint of the similar interval and the front endpoint of the healing interval corresponding to the latest period.
[0082] Step S602: Calculate the segment similarity based on the interval spans of all similar intervals and the corresponding similarity ratios, and define the candidate user corresponding to the segment similarity with the largest value as the control user of the current user.
[0083] The segmented similarity is a value obtained by dividing the similarity ratio by the corresponding interval span and adding them all up. The calculation of this segmented similarity can strengthen the judgment of the similarity of recent cures and weaken the judgment of the similarity of periods far apart. At this time, the larger the segmented similarity, the more similar the corresponding candidate user is to the current user's cure. Therefore, the candidate user corresponding to the segmented similarity with a large value can be determined as the control user.
[0084] Wound care device control methods also include: Step S700: Obtain an external receiving instruction.
[0085] The external receiving command is a command input by an external nursing staff, and the signal can be input through the touch panel.
[0086] Step S701: When the externally received instruction is consistent with the preset disinfection instruction, the disinfection device preset on the wound surface is controlled to perform a disinfection operation.
[0087] The disinfection instruction is an externally received instruction that requires the wound to be disinfected. When the externally received instruction is consistent with the disinfection instruction, it means that the nursing staff needs to disinfect the wound. At this time, the disinfection device can be controlled to perform the disinfection operation. The method of disinfection by the disinfection device can be to spray medical disinfectant. The specific setting is determined by the staff according to the actual situation and will not be elaborated here.
