[0002] At present, when giving blood transfusion (or drug transfusion) to patients, for some patients who have lost too much blood and urgently need blood transfusion (such as pregnant women with heavy bleeding or severe blood loss due to injuries, etc.), the speed of conventional blood transfusion (or drug transfusion) cannot meet the rescue requirements. In order to increase the speed of blood transfusion (or drug transfusion) and allow the blood from the blood bank and the bagged liquid to enter the human body as quickly as possible, it is necessary to pressurize the blood transfusion (or drug transfusion) through a pressurizer.

[0003] During the use of the pressurizer, the pressurized bag may leak, causing the pressure value in the pressurized bag to decrease, thereby reducing the speed of blood transfusion (or drug transfusion). In addition, the pressurized bag is monitored manually and leaks in the pressurized bag cannot be detected in time. Summary of the invention

[0027] The present application is further described in detail below in conjunction with the accompanying drawings.

[0028] After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of this application.

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] In addition, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally means that the associated objects before and after are in an "or" relationship.

[0031] The embodiments of the present application are further described in detail below in conjunction with the drawings in the specification.

[0032] The embodiment of the present application provides a blood transfusion and infusion pressurization control method, which is executed by a pressurization instrument body, and the pressurization instrument body can be a server or a terminal device, wherein the server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides cloud computing services. The terminal device can be a smart phone, a tablet computer, a laptop computer, a desktop computer, etc., but is not limited to this. The terminal device and the server can be directly or indirectly connected via wired or wireless communication, and the embodiment of the present application does not limit this. Figure 1 As shown, the method includes step S101, step S102, step S103, step S104 and step S105, wherein: S101, obtaining image information of the pressurization bag, screen display data of the pressurization instrument, and a pressure change diagram in the pressurization bag after the pressurization instrument is turned on.

[0033] With respect to the embodiments of the present application, when administering an infusion to an emergency patient, the patient usually needs to be rapidly infused or transfused, but ordinary infusion devices are difficult to achieve the infusion speed required by the doctor's order. Therefore, the infusion bag can be placed in a pressurized bag connected to the pipeline of the pressurizing instrument body for pressurization, thereby pressurizing the infusion bag and achieving the infusion speed required by the doctor's order. When the pressurizing instrument is in use, the camera device can be directed toward the pressurized bag, thereby collecting image information of the pressurized bag. The camera device is wiredly connected to the pressurizing instrument body, and the pressurizing instrument body obtains image information of the pressurized bag so as to timely understand the pressurization status of the pressurized bag.

[0034] The pressure data in the pressurizing bag is displayed on the screen, and the pressurizing instrument body obtains the screen display data of the pressurizing instrument, which is convenient for the staff to understand the pressure setting of the display screen.

[0035] When the pressurizer is turned on, the pressure inside the pressurization bag begins to increase rapidly. The gas pressure sensor in the pressurization bag can collect the pressure value in the pressurization bag. The gas pressure sensor is wirelessly connected to the pressurizer body. The pressurizer body obtains and generates a pressure change graph in the pressurization bag after the pressurizer is turned on.

[0036] S102, determining the sealing degree of the pressurized bag based on the screen display data and the pressure change diagram.

[0037] For the embodiment of the present application, the screen data of the pressurizing instrument and the pressure change diagram of the pressurizing bag can reflect the sealing condition of the pressurizing bag. Therefore, the pressurizing instrument body determines the sealing degree of the pressurizing bag based on the screen data and the pressure change diagram.

[0038] S103: If the sealing degree is within the preset sealing range, determine the liquid content of the infusion bag in the pressurized bag based on the image information.

[0039] For the embodiment of the present application, the preset sealing range is a range set when the pressurized bag has a slight leak but can still be used. If the sealing degree is within the preset sealing range, the pressurizing instrument body recognizes the image information, determines the position of the liquid in the infusion bag in the pressurized bag, and then determines the liquid content of the infusion bag.

[0040] S104, determining a target pressure value of the pressurizer based on the liquid content, sealing degree, pressure variation graph, and screen display data.

[0041] With respect to the embodiments of the present application, after the pressurized bag is pressurized, the amount of liquid content will affect the infusion speed, and the sealing degree is related to the air leakage of the pressurized bag. If the sealing degree is too low, the pressure in the pressurized bag will be smaller. If the pressure difference between the pressure change graph in the pressurized bag and the screen data of the pressurizer is too large, it further indicates that the pressure in the pressurized bag is too small, and the infusion bag cannot be pressurized, which in turn causes the infusion speed to slow down. Therefore, the pressurizer body determines the target pressure value of the pressurizer based on the liquid content, sealing degree, pressure change graph, and screen data.

[0042] S105, controlling the pressure instrument to adjust according to the target pressure value.

[0043] For the embodiment of the present application, the pressurizing instrument body controls the pressurizing instrument to adjust according to the target pressure value, so that the pressure in the pressurized bag is increased. The sealing degree of the pressurized bag is determined according to the screen data of the pressurizing instrument and the pressure change diagram of the pressurized bag. If the pressurized bag leaks but can continue to be used, that is, the sealing degree is within the preset sealing range, the target pressure value of the pressurizing instrument is determined based on the liquid content, sealing degree, pressure change diagram, and screen data, and then the pressurizing instrument is controlled to adjust according to the target pressure value, which can timely detect the leakage of the pressurized bag and effectively adjust the pressure value of the pressurizing instrument, so that the infusion bag can reach the infusion speed required by the doctor's order.

[0044] In a possible implementation of the embodiment of the present application, the sealing degree of the pressurized bag is determined based on the screen display data and the pressure change diagram in step S102, specifically including step S1021 (not shown in the figure), step S1022 (not shown in the figure), step S1023 (not shown in the figure), step S1024 (not shown in the figure), step S1025 (not shown in the figure) and step S1026 (not shown in the figure), wherein: Step S1021, determining the initial pressure value and the maximum pressure value in the pressurized bag, and the pressurization time used to reach the maximum pressure value for the first time based on the pressure change diagram.

[0045] For the embodiments of the present application, the pressure change graph shows the pressure change in the pressurization bag after the pressurizer is turned on. The pressurizer body determines the initial pressure value in the pressurization bag and the maximum pressure value reached after the pressurization bag is pressurized based on the pressure change graph, and determines the pressurization time used to reach the maximum pressure value for the first time. The pressurization bag may not leak initially during the pressurization process, but after reaching a certain pressure value, cracks will appear on the edge of the pressurization bag due to the change in pressure, causing slight leakage in the pressurization bag. Therefore, the pressurization bag leaks while pressurizing, which in turn causes the pressurization time of the pressurization bag to become longer. The pressurization time reflects the pressurization speed of the pressurization bag and the speed of leakage of the pressurization bag.

[0046] Step S1022, determining a set pressure value in the screen display data, and determining a first difference between the maximum pressure value and the set pressure value.

[0047] For the embodiment of the present application, the screen display data of the pressurizing instrument includes the set pressure value set by the staff for the patient. The pressurizing instrument body determines the set pressure value through the screen display data, and determines the first difference between the maximum pressure value reached by the pressurization bag and the set pressure value. The first difference reflects the degree of leakage of the pressurization bag.

[0048] Step S1023, determining the pressure increase rate of each preset time period within the boost time based on the pressure change diagram.

[0049] For the embodiment of the present application, the pressurizing instrument body determines the pressure growth rate of each preset time period within the pressurization time based on the pressure change diagram.

[0050] Step S1024, determining the total number of preset time periods, and determining the number of times the pressure growth rate reaches the preset growth rate.

[0051] For the embodiment of the present application, the pressurizing instrument body determines the total number of preset time periods and determines the number of times the pressure growth rate reaches the preset growth rate. For example, the pressurization time of the pressurization bag is 40 seconds, and the preset time period is set to 1 second, then the total number of preset time periods is 40 / 1=40.

[0052] Step S1025, determining a first ratio of the number to the total number.

[0053] For the embodiment of the present application, the pressurizing instrument body determines a first ratio of the number to the total number. For example, if the total number is 40 and the number at which the pressure growth rate reaches the preset growth rate is 30, the first ratio is 30 / 40=0.75.

[0054] Step S1026, determining a first score based on the first ratio, the first difference, the boost time, and respective first coefficients.

[0055] The first score represents the sealing degree of the pressurized bag.

[0056] For the embodiment of the present application, the first ratio characterizes the stability of pressurization of the pressurized bag, and the first difference and the pressurization time both reflect the degree of leakage of the pressurized bag. Therefore, the pressurizer body determines the first score based on the first ratio, the first difference, the pressurization time and the respective first coefficients. The first score characterizes the sealing degree of the pressurized bag. The lower the first score, the worse the sealing condition of the pressurized bag.

[0057] In a possible implementation of the embodiment of the present application, in step S1023, the pressure growth rate of each preset time period within the boost time is determined based on the pressure change diagram, specifically including step S1 (not shown in the figure), step S2 (not shown in the figure) and step S3 (not shown in the figure), wherein: Step S1, determining a first pressure value at every preset time period within a boost time based on a pressure variation diagram.

[0058] According to the embodiment of the present application, the pressurizing instrument body determines the first pressure value at every preset time period within the pressurization time based on the pressure change diagram.

[0059] Step S2, determining a second difference between every two adjacent first pressure values.

[0060] According to the embodiment of the present application, the pressurizing instrument body determines the second difference between every two adjacent first pressure values.

[0061] Step S3, determining a second ratio of the second difference to the preset time period. The second ratio is the pressure growth rate in each preset time period.

[0062] For the embodiment of the present application, the pressurizing instrument body determines the second ratio of the second difference to the preset time period, that is, the slope of each preset time period in the pressure change diagram, that is, the pressure growth rate of each preset time period. The pressure growth rate reflects the pressure boost situation in each preset time period. If the values ​​are the same, it means that the boost rate is stable. If the values ​​are different, it means that the boost rate is unstable.

[0063] In a possible implementation of the embodiment of the present application, in step S104, the target pressure value of the pressurizer is determined based on the liquid content, the sealing degree, the pressure change diagram, and the screen data, specifically including step S1041 (not shown in the figure), step S1042 (not shown in the figure), step S1043 (not shown in the figure), and step S1044 (not shown in the figure), wherein: Step S1041, determining the current pressure value in the pressurized bag based on the pressure change graph.

[0064] For the embodiment of the present application, the pressure change graph is a pressure change graph obtained by the pressurizing instrument body up to the current time. The pressurizing instrument body determines the current pressure value in the pressurizing bag based on the pressure change graph, that is, the pressure value corresponding to the last time in the pressure change graph.

[0065] Step S1042, determining a third difference between the current pressure value and the set pressure value in the screen display data.

[0066] With respect to the embodiment of the present application, the pressurization bag is pressurized and, under normal circumstances, it will take a certain period of time to reach the set pressure value on the screen display of the pressurizer. However, if it cannot be reached, it means that the pressurization bag may be leaking. Therefore, the pressurizer body determines the third difference between the current pressure value and the set pressure value in the screen display. The larger the third difference, the more leaks there are in the pressurization bag.

[0067] Step S1043, determining a second score based on the liquid content, the sealing degree, the third difference and the respective second coefficients.

[0068] For the embodiment of the present application, the liquid content, sealing degree and the third difference are all important factors affecting the pressure value of the adjustment pressurizer. Therefore, the pressurizer body determines the second score based on the liquid content, sealing degree, the third difference and the respective second coefficients.

[0069] Step S1044, determining a target pressure value of the pressurizing instrument based on the second score.

[0070] For the embodiment of the present application, the pressurizing instrument body determines the preset score range in which the second score is located, and then determines the target pressure value corresponding to the preset score range. The lower the second score, the higher the corresponding target pressure value should be.

[0071] In a possible implementation of the embodiment of the present application, step S105 further includes step 1, step 2, and step 3, wherein: Step 1: After the pressurizing instrument is adjusted to the target pressure value and a preset target time has passed, a second pressure value in the pressurizing bag is obtained.

[0072] For the embodiment of the present application, when the pressurizing instrument is adjusted to the target pressure value and after a preset target time has passed, the pressurizing instrument body obtains a second pressure value in the pressurizing bag.

[0073] Step 2: determine whether the second pressure value reaches the set pressure value.

[0074] For the embodiment of the present application, the pressurized bag should reach the set pressure value after adjustment of the preset target time. The pressurizing instrument body determines whether the second pressure value reaches the set pressure value. If so, the pressurized bag can continue to be used, indicating that the infusion speed required by the doctor's order can be achieved in this case.

[0075] Step 3: If not reached, output a prompt message.

[0076] For the embodiment of the present application, if it is not achieved, the pressurizing instrument body can output a prompt message with the words "pressurizing bag abnormality" to the staff's terminal device, so that the staff can replace the pressurizing bag in time.

[0077] In a possible implementation manner of the embodiment of the present application, the method further includes step 4, step 5, step 6, step 7 and step 8, wherein step 4 may be performed after step S105, wherein: Step 4: Determine the historical usage times and specifications of the pressurized bag.

[0078] With respect to the embodiment of the present application, the pressurized bag is a reusable item. Multiple pressurization and depressurization of the pressurized bag will cause certain wear and tear on the bag body and increase the possibility of cracks in the pressurized bag. The pressurizer records each use of the pressurized bag, and the pressurizer body determines the historical number of uses of the pressurized bag, which reflects the wear and tear of the pressurized bag.

[0079] Step five: determine the specifications of the infusion bag in the pressurized bag based on the image information.

[0080] For the embodiment of the present application, the pressurizing instrument body has pre-stored pictures of various specifications of infusion bags placed in the pressurizing bag, so the pressurizing instrument body can determine the specifications of the infusion bag in the pressurizing bag based on the image information by comparing the photos.

[0081] Step six, determining the third ratio of the infusion bag specification to the pressurized bag specification.

[0082] For the embodiment of the present application, the pressurizing instrument body determines the third ratio of the specifications of the infusion bag and the specifications of the pressurizing bag. The smaller the third ratio is, the greater the damage to the pressurizing bag caused by pressurizing the pressurizing bag, and the greater the possibility of cracks.

[0083] Step seven, determining a third score based on the historical usage times, the third ratio and the respective third coefficients.

[0084] For the embodiment of the present application, the pressurizing instrument body determines the third score based on the historical usage times, the third ratio and the respective third coefficients. The lower the third score, the worse the quality of the pressurized bag. The third coefficient can be adjusted according to actual conditions.

[0085] Step eight, determining an adjustment value corresponding to the third score, and adjusting the target pressure value based on the adjustment value.

[0086] For the embodiment of the present application, the pressurizing instrument body determines the adjustment value corresponding to the third score, and adjusts the target pressure value by subtracting the adjustment value, thereby reducing the target pressure value to avoid the situation where the pressure in the pressurizing bag is too high and causes cracks in the pressurizing bag as much as possible.

[0087] In a possible implementation manner of the embodiment of the present application, the method further includes step nine, step ten and step eleven, wherein: Step nine, obtaining the first blood pressure before adjustment and the second blood pressure after adjustment of the patient by the pressor.

[0088] The first blood pressure includes a first systolic pressure and a first diastolic pressure, and the second blood pressure includes a second systolic pressure and a second diastolic pressure.

[0089] For the embodiment of the present application, after the pressurizer is adjusted, the gas pressure inside the pressurized bag will be greater, thereby increasing the infusion speed. Rapid infusion will cause a rapid increase in blood volume, which can cause blood pressure to rise. For patients with heart failure or hypertension, it may increase the burden on the heart and cause danger. Therefore, the pressurizer body obtains the first blood pressure before adjustment and the second blood pressure after adjustment of the pressurizer corresponding to the patient. The first blood pressure and the second blood pressure reflect the changes in the patient's state before and after the adjustment of the pressurizer.

[0090] Step ten: determining a systolic blood pressure change value and a diastolic blood pressure change value of the patient based on the first blood pressure and the second blood pressure.

[0091] For the embodiment of the present application, the increase in blood pressure may be an increase in systolic pressure or an increase in diastolic pressure. Therefore, the pressor body determines the systolic pressure change value based on the first systolic pressure and the second systolic pressure, and determines the diastolic pressure change value based on the first diastolic pressure and the second diastolic pressure.

[0092] Step eleven: if the systolic pressure change value exceeds a preset change threshold and / or the diastolic pressure change value exceeds a preset change threshold, the pressurizer is controlled to be turned off.

[0093] For the embodiment of the present application, if the fluctuation of blood pressure before and after adjustment of the pressurizer is too large, it means that the patient may not adapt to the infusion speed, have excessive drug reaction or other reasons. The pressurizer body judges the systolic blood pressure change value and the diastolic blood pressure change value. If there are three situations in which the systolic blood pressure change value exceeds the preset change threshold, or the diastolic blood pressure change value exceeds the preset change threshold, or the systolic blood pressure change value and the diastolic blood pressure change value both exceed the preset change threshold, it means that the patient has a serious adverse reaction to the adjustment of the pressurizer, and the pressurizer needs to be controlled and shut down as soon as possible.
