Description

Background Art

[0002] At present, most medical institutions rely mainly on patients to call nurses to remind them that the infusion is complete when the infusion is finished. However, this traditional method has several potential problems. First, because patients may be in a state of sleep, coma or inattention, they may not be able to detect the end of the infusion in time, resulting in continued infusion of air into the intravenous channel after the liquid in the infusion bottle is exhausted, causing discomfort to the patient and even serious consequences. Secondly, even if the patient can find the end of the infusion in time, they may not be able to call the nurse in time or effectively due to various reasons (such as weakness, pain, etc.), resulting in delayed processing after the end of the infusion. Therefore, there is an urgent need for a method that can promptly remind medical staff that the infusion is about to end, which is of great significance to improving the efficiency and safety of medical care. Summary of the invention

[0013] In a second aspect of the present application, an infusion prompt device is provided, which is applied to a target infusion stand, wherein a pressure sensor is provided at a hook for hanging an infusion bottle on the target infusion stand, and the pressure sensor is connected to a communication module;

[0014] The device comprises:

[0015] An acquisition unit, used to acquire the initial weight CZ of the drug solution in the target infusion bottle;

[0016] The first acquisition unit is used for, in response to receiving the infusion start signal, controlling the pressure sensor to acquire the pressure value at the hook at intervals of a first time period within a first time window to obtain a first pressure value list YL=(YL1, YL2, ..., YL i , …, YL n ); i = 1, 2, ..., n; where n is the number of pressure values ​​collected in the first time window; YL i is the i-th pressure value collected in the first time window;

[0017] A first determining unit, configured to obtain an initial reminder time YT according to YL and a preset reminder time XT, and determine YT as a target reminder time;

[0018] The second acquisition unit is used to control the pressure sensor to acquire the current pressure value DY at the hook once every second time period before reaching the target reminder time, so as to obtain the current pressure difference DC; wherein DC meets the following conditions: DC=DY-SY; SY is the pressure value acquired last time before the current pressure value;

[0019] The third acquisition unit is used for controlling the pressure sensor to acquire the pressure value at the hook at intervals of a third time period within the second time window if DC-BC>YC, so as to obtain an updated pressure value list EL=(EL1, EL2, ..., EL j ,…,EL m ), j = 1, 2, ..., m, where m is the number of pressure values ​​collected in the second time window, EL j is the j-th pressure value collected in the second time window; wherein BC is the standard pressure difference; the start time of the second time window is the time when DC-BC>YC is determined; YC is the preset pressure difference threshold;

[0021] The sending unit is used to control the communication module to send the ET to the target display device, and control the target display device to initiate an infusion end alarm when the ET is reached.

[0022] In a third aspect of the present application, a non-transitory computer-readable storage medium is provided, in which at least one instruction or at least one program is stored, and the at least one instruction or at least one program is loaded and executed by a processor to implement the aforementioned infusion prompt method.

[0023] In a fourth aspect of the present application, an electronic device is provided, comprising a processor and the above-mentioned non-transitory computer-readable storage medium.

[0024] This application has at least the following beneficial effects:

[0025] The infusion reminder method provided by the present application first obtains the initial weight CZ of the medicine in the target infusion bottle. After the infusion starts, the medical staff will set a reasonable infusion speed, and the medicine in the target infusion bottle will gradually decrease. In the first time window, at each first time period, the pressure sensor is controlled to collect the pressure value at the hook. According to the change in the pressure of the infusion bottle, the change in the weight of the medicine in each first time period can be derived, and then the average flow rate of the medicine outflowing from the infusion bottle in the first time window can be inferred. Furthermore, the predicted time to end the infusion can be obtained. In the present application, XT is a preset reminder duration, that is, the time length from the time of the infusion end reminder to the predicted infusion end time. According to YL and the preset reminder duration XT, the initial reminder time YT can be determined.

[0026] However, in actual infusion, the patient or medical staff may adjust the infusion speed. When adjusting, it will cause the infusion bottle to shake or apply a certain pressure to the infusion bottle. At this time, the pressure value at the hook of the pressure sensor will change significantly. Adjusting the infusion speed will cause the end time of the infusion to change, so the above-mentioned initial reminder time will also change. Therefore, in order to be able to detect the action of adjusting the infusion speed in this application, before reaching the target reminder time, every second time period, the pressure sensor is controlled to collect the current pressure value DY at the hook once to obtain the current pressure difference DC. If DC-BC>YC, that is, the difference between the current pressure difference DC and the standard pressure difference is greater than the preset pressure difference threshold; it means that the current pressure difference is large, which may be caused by the shaking of the infusion bottle or the application of a certain pressure to the infusion bottle when the patient or medical staff adjusts the infusion speed. At this time, it is necessary to re-collect the pressure value within a period of time to update the above-mentioned initial reminder time. Then the updated reminder time ET is obtained. During the whole infusion process, multiple infusion adjustment actions may be detected. Therefore, after updating the reminder time once, before the reminder time is reached, the process continues to jump to step S400 to continue pressure value detection until the update reminder time is reached. Finally, after the latest update reminder time ET is reached, the communication module is controlled to send ET to the target display device, and the target display device is controlled to initiate an infusion end alarm when ET is reached.

[0027] This application senses the pressure change through the pressure sensor set at the hook of the infusion stand to obtain the predicted end time of infusion, and can send the reminder time to the medical staff through the set communication module before the end. So that the infusion end alarm can be triggered before the end of the infusion, even reminding the medical staff to change the fluid or end the infusion. There is no need for patients and medical staff to check the infusion bottle frequently. It saves manpower. In addition, this application can detect the adjustment of the infusion speed by the patient or medical staff through the change of pressure, and then continuously update the reminder time of the end of the infusion during the entire infusion process, so that the medical staff can accurately grasp the end time of the infusion for each patient. It can change the fluid or end the infusion for the patient in time. Reduce the probability of danger. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Please refer to Figure 1 As shown, an embodiment of the present application provides an infusion prompt method, which is applied to a target infusion stand, where a pressure sensor is provided at a hook for hanging an infusion bottle on the target infusion stand, and the pressure sensor is connected to a communication module;

[0035] The method comprises:

[0036] S100, obtaining the initial weight CZ of the drug solution in the target infusion bottle.

[0037] Specifically, the acquisition method may be manual input by medical staff or identification by a handheld device of medical staff. It should be noted that multiple infusion bottles may be hung on the same infusion stand at the same time. CZ is the initial weight of the liquid medicine in the target infusion bottle that is about to start infusion.

[0038] S200, in response to receiving the infusion start signal, control the pressure sensor to collect the pressure value at the hook at intervals of a first time period within the first time window to obtain a first pressure value list YL=(YL1, YL2, ..., YL i , …, YL n ); i = 1, 2, ..., n; where n is the number of pressure values ​​collected in the first time window; YL i is the i-th pressure value collected in the first time window.

[0039] Specifically, after the infusion begins, the liquid in the target infusion bottle gradually decreases, and the pressure sensor is controlled to collect the pressure value at the hook at every first time period in the first time window. As an example: the first time window can be 60 seconds, and the first time period can be 5 seconds.

[0040] S300, obtaining an initial reminder time YT according to YL and a preset reminder time XT, and determining YT as a target reminder time.

[0041] Specifically, when starting the infusion, the medical staff will set a reasonable infusion speed. The change in the pressure of the infusion bottle can be used to deduce the change in the weight of the liquid medicine in each first time period, and then the average flow rate of the liquid medicine flowing out of the infusion bottle in the first time window can be inferred. Furthermore, the predicted time to end the infusion can be obtained.

[0042] In this embodiment, XT is a preset reminder duration, i.e., the time length from the time of the infusion end reminder to the predicted infusion end time. For example, if XT is 10 minutes, the infusion end alarm is issued 10 minutes before the predicted infusion end time. Then, according to YL and the preset reminder duration XT, the initial reminder time YT can be determined.

[0043] Specifically, step S300 includes:

[0044] S310, according to YL, obtain the average flow YS in the first time window, and YS meets the following conditions:

[0045] YS=(Σ n i=2 f(YL i -YL i-1 )) / (n-1);

[0046] Among them, f() is the preset flow calculation function.

[0047] Here, firstly, n-1 pressure differences are obtained, and then the weight difference of the liquid medicine can be obtained according to each pressure difference, and the volume of the liquid medicine can be obtained according to each weight difference of the liquid medicine and the concentration of the liquid medicine; and then the flow rate corresponding to each pressure difference can be obtained according to the time interval of obtaining two adjacent pressure differences. Then, the average flow rate in the first time window is obtained according to the n-1 pressure differences.

[0048] S320, according to YS and the preset reminder duration XT, the initial reminder time YT is obtained, and YT meets the following conditions:

[0049] YT=(g(CZ) / YS)+KT-XT;

[0050] Wherein, KT is the start time of infusion; g() is the preset volume calculation function.

[0051] Here, the initial volume of the liquid in the target infusion bottle is obtained according to g(CZ), and then (g(CZ) / YS) represents the time required for the liquid in the target infusion bottle to be infused when the currently set infusion speed remains unchanged. KT is the infusion start time, and XT is the preset reminder time, that is, the initial reminder time YT is obtained according to (g(CZ) / YS)+KT-XT. As an example: (g(CZ) / YS) is 30min; KT is 8:15; XT is 10min; then YT=8:35. That is, the infusion end alarm is issued at 8:35.

[0052] S400, before reaching the target reminder time, control the pressure sensor to collect the current pressure value DY at the hook once every second time period to obtain the current pressure difference DC; wherein DC meets the following conditions: DC=DY-SY; SY is the pressure value collected last time before the current pressure value.

[0053] Specifically, during actual infusion, the patient or medical staff may adjust the infusion speed. When adjusting, the infusion bottle may shake or a certain pressure may be applied to the infusion bottle. At this time, the pressure value at the hook of the pressure sensor may change significantly. Adjusting the infusion speed will cause the end time of the infusion to change, and the initial reminder time will also change. Therefore, in this embodiment, in order to detect the action of adjusting the infusion speed, before reaching the target reminder time, the pressure sensor is controlled to collect the current pressure value DY at the hook every second time period to obtain the current pressure difference DC.

[0054] S500, if DC-BC>YC, then control the pressure sensor to collect the pressure value at the hook at every third time interval within the second time window to obtain an updated pressure value list EL=(EL1, EL2, ..., EL j ,…,ELm ), j = 1, 2, ..., m, where m is the number of pressure values ​​collected in the second time window, EL j is the j-th pressure value collected in the second time window; wherein BC is the standard pressure difference; the start time of the second time window is the time for determining DC-BC>YC; and YC is the preset pressure difference threshold.

[0055] Specifically, if DC-BC>YC, that is, the difference between the current pressure difference DC and the standard pressure difference is greater than the preset pressure difference threshold;

[0056] This indicates that the current pressure difference is large, which may be due to the shaking of the infusion bottle or the application of a certain pressure to the infusion bottle when the patient or medical staff adjusts the infusion speed. At this time, it is necessary to re-collect the pressure value within a period of time to update the above initial reminder time. The length of the second time window can be equal to the length of the first time window. The length of the third time period can be equal to the length of the first time period.

[0057] Here, BC is the standard pressure difference, BC=(Σ n i=2 (YL i -YL i-1 )) / (n-1). This is the average value of the n-1 pressure differences obtained in the initial stage of the infusion.

[0058] It should be noted that if DC is greater than BC, it means that the current pressure difference has increased, which may be caused by a variety of reasons, such as wind, being hit, etc. When DC-BC>YC, it means that the pressure difference has increased significantly, which is likely due to the shaking of the infusion bottle or the application of a certain pressure to the infusion bottle when the patient or medical staff adjusts the infusion speed.

[0059] S600, obtaining an updated reminder time ET according to EL and a preset reminder time XT, and determining ET as a target reminder time; and jumping to step S400, until the target reminder time is reached.

[0060] Specifically, according to the above content: it may be due to the shaking of the infusion bottle or the application of a certain pressure to the infusion bottle when the patient or medical staff adjusts the infusion speed, that is, the infusion speed has changed. At this time, the updated EL is obtained. According to the updated EL, the change value of the weight of the liquid medicine at each third time period can be deduced, and then the average flow rate of the liquid medicine flowing out of the infusion bottle in the second time window can be inferred. Further, the updated (possibly after the infusion speed is adjusted) predicted time to end the infusion can be obtained. Then the updated reminder time ET is obtained. The process here is the same as the step S200, which will not be repeated.

[0061] S610, according to EL, obtain the corresponding pressure difference fluctuation value LB, LB meets the following conditions:

[0062] LB=(∑ m j=1 (EL j -avg(EL)) 2 ) / m.

[0063] Here, firstly, the fluctuation degree of the updated EL obtained in the second time window is obtained. If LB is large, it means that the shaking may not end at this time, resulting in unstable pressure difference in the second time window and a large pressure difference. On the contrary, if LB is small, it means that there is no excessive or small pressure difference in EL, and the pressure difference is similar in size, that is, the shaking may have ended at this time, and the target infusion bottle has stabilized.

[0064] S620: If LB is less than the preset fluctuation value threshold, then the average flow ES in the second time window is obtained according to EL, and ES meets the following conditions:

[0065] ES=(Σ m j=2 f(EL j -EL j-1 )) / (m-1).

[0066] Here, if LB is less than the preset fluctuation value threshold, it means that there is no excessive or too small pressure difference in EL, and the pressure differences are similar in size, that is, the shaking may have ended at this time, and the target infusion bottle has stabilized. At this time, the weight difference of the drug solution can be obtained according to the m-1 pressure differences, and the volume of the drug solution can be obtained according to each weight difference of the drug solution and the concentration of the drug solution; and then according to the time interval between the acquisition of two adjacent pressure differences, the flow rate corresponding to each pressure difference can be obtained. The average flow rate in the second time window is obtained according to the m-1 pressure differences.

[0067] S630: According to ES and the preset reminder duration XT, an updated reminder time ET is obtained, where ET meets the following conditions:

[0068] ET=(g(EL m ) / ES)+DT-XT;

[0069] Among them, DT is the current time.

[0070] Here, according to g(EL m ) to obtain the current volume of the liquid in the target infusion bottle, and then (g(EL m ) / ES) indicates the time required to infuse the liquid in the target infusion bottle according to the updated infusion speed. DT is the current time, and XT is the preset reminder time, that is, according to (g(EL m) / ES)+DT-XT gets the update reminder time ET.

[0071] It should be noted that, during the entire infusion process, multiple infusion adjustment actions may be detected. Therefore, after updating the reminder time once, before the reminder time is reached, the process continues to jump to step S400 to continue pressure value detection.

[0072] S700, controlling the communication module to send ET to the target display device, and controlling the target display device to initiate an infusion end alarm when ET is reached.

[0073] Specifically, after reaching the latest update reminder time ET, the communication module is controlled to send ET to the target display device, and the target display device is controlled to initiate an infusion end alarm when ET is reached. The target display device can be a computer at a nurse station or a mobile phone of a medical staff.

[0074] This embodiment senses the pressure change through the pressure sensor installed on the hook of the infusion stand to obtain the predicted end time of the infusion, and can send the reminder time to the medical staff through the communication module before the end. So that the infusion end alarm can be triggered before the end of the infusion, even reminding the medical staff to change the fluid or end the infusion. There is no need for patients and medical staff to check the infusion bottle frequently. Manpower is saved. In addition, this embodiment can detect the adjustment of the infusion speed by the patient or medical staff through the change of pressure, and then continuously update the reminder time of the end of the infusion during the entire infusion process, so that the medical staff can accurately grasp the end time of the infusion for each patient. It is possible to change the fluid or end the infusion for the patient in time. Reduce the probability of danger.

[0075] In an exemplary embodiment of the present application, after step S400, the method further includes:

[0076] S800: If DC-BC≤YC, jump to step S400 until the target reminder time is reached.

[0077] Specifically, if DC-BC≤YC, it means that the current pressure difference increases, but the increase is not large, which may be caused by wind or other reasons, and no processing is performed. The process jumps to step S400 to continue monitoring.

[0078] S900: If EL is empty, according to YT, use the communication module to send an infusion end alarm to the target display device.

[0079] Specifically, if EL is empty during the entire monitoring process, it means that the patient or the medical staff has not adjusted the infusion speed and the infusion is always performed according to the initial infusion speed. That is, at this time, according to YT, the communication module sends an infusion end alarm to the target display device.

[0080] In an exemplary embodiment of the present application, after step S610, the method further includes:

[0081] S640, if LB is equal to or greater than the preset fluctuation value threshold, then control the pressure sensor to collect the pressure value at the hook at every fourth time period within the third time window to obtain a key pressure value list SL = (SL1, SL2, ..., SL j ,…,SL m ), j = 1, 2, ..., m, where m is the number of pressure values ​​collected in the second time window, SL j is the j-th pressure value collected in the third time window; the time length of the third time window is equal to the second time window and the time length of the fourth time period is equal to the third time period; the start time of the third time window is the end time of the second time window;

[0082] S650, according to SL, the corresponding pressure difference fluctuation value SB is obtained, and SB meets the following conditions:

[0083] SB=(∑ m j=1 (SL j -avg(SL)) 2 ) / m;

[0084] S620: If SB is less than the preset fluctuation value threshold, then the average flow rate SS in the third time window is obtained according to SL, and SS meets the following conditions:

[0085] SS=(Σ m j=2 f(SL j -SL j-1 )) / (m-1);

[0086] S630, according to SS and the preset reminder time XT, a critical reminder time ST is obtained, and ST meets the following conditions:

[0087] ST=(g(SL m ) / SS)+DT-XT.

[0088] S640, determining ST as the target reminder time; and jumping to step S400, until the target reminder time is reached.

[0089] In this embodiment, if LB is equal to or greater than the preset fluctuation value threshold, it means that the shaking may not end at this time, resulting in unstable pressure difference in the second time window and a large pressure difference. At this time, if the corresponding pressure difference is used to calculate the average flow, it is inaccurate. Therefore, in the third time window after the second time window ends, continue to obtain the key pressure value list. And obtain its corresponding fluctuation value. If the fluctuation value is less than the preset fluctuation value threshold, it means that the shaking is basically over, and SL can be used to obtain the updated reminder time. The steps for determining the reminder time are the same as the above steps and will not be repeated here.

[0090] In an exemplary embodiment of the present application, the target infusion stand is in a target area, and in addition to the target infusion stand, a plurality of infusion stands are arranged in the target area, and each infusion stand is provided with a communication module. After step S600, the method further includes:

[0091] S1000, obtaining the difference between each infusion reminder time and ET of each infusion stand other than the target infusion stand in the target area;

[0092] S1100, the infusion reminder time of each infusion stand except the target infusion stand in the target area whose difference between the infusion reminder time and the ET is less than a preset time difference threshold is adjusted to the ET, and the process jumps to step S700.

[0093] In this embodiment, several infusion reminder times with similar reminder times in the target area are adjusted to ET and combined to remind each other, which can reduce the amount of data transmission.

[0094] When the ET is sent to the target display device, the corresponding identifiers of several infusion stands are also sent to the target device at the same time, so that the medical staff can determine the corresponding infusion tasks to be processed.

[0095] The following is a complete example to illustrate an infusion prompt method provided by the present application:

[0096] A male patient with pneumonia, normal heart function, was treated with ceftizoxime, twice a day, 2 vials (2g) each time. 100ml 0.9% sodium chloride was used for intravenous infusion. Bottle weight: 107g, liquid density of 1.0g / ml, liquid volume of 100ml, first, the initial weight of the liquid in the infusion bottle was obtained CZ = 1.0g / ml × 100ml = 100g; secondly, the duration of the first time window was set to 2min, the first time period was 5s, 1ml of liquid was counted as 20 drops, and the liquid was infused at a rate of 30 drops per minute, that is, the weight of the liquid changed by 0.125g every five seconds. In response to receiving the infusion start signal, YL was obtained every 1s within 2min; according to YL. The average flow rate YS in the first time window was obtained, YS = 1.5ml / min. Set the preset reminder time to 10 minutes. If the infusion start time is 8:00, then YT = (100ml / (1.5ml / min)) + 8:00:00 - 10min = 8:56:40. That is, for the infusion task started at 8:00, the infusion end alarm will be issued at 8:56:40.

[0097] It should be noted that if the drip rate is adjusted during the infusion, the time for issuing the above-mentioned infusion end alarm is recalculated and updated according to the adjusted flow rate, which is the same as the above-mentioned calculation steps and will not be repeated here.

[0098] Please refer to Figure 2 As shown, an embodiment of the present application provides an infusion prompt device 100, which is applied to a target infusion stand, and a pressure sensor is provided at a hook for hanging an infusion bottle on the target infusion stand, and the pressure sensor is connected to a communication module;

[0099] The device comprises:

[0100] The acquisition unit 110 is used to acquire the initial weight CZ of the drug solution in the target infusion bottle.

[0101] The first acquisition unit 120 is used for, in response to receiving the infusion start signal, controlling the pressure sensor to acquire the pressure value at the hook at intervals of a first time period within a first time window to obtain a first pressure value list YL=(YL1, YL2, ..., YL i , …, YL n ); i = 1, 2, ..., n; where n is the number of pressure values ​​collected in the first time window; YL i is the i-th pressure value collected in the first time window.
