[0059] Reference Figure 1 As shown, an embodiment of the present invention provides a fluid infusion device, including: a housing 110, a chamber fluid box 120, a first liquid storage box 131, a first catheter 141, an infusion unit, an input unit 170 and a controller 160. The housing 110 is provided with a cavity; the chamber fluid box 120 is fixed in the cavity; the first liquid storage box 131 is fixed in the chamber fluid box 120, and the first liquid storage box 131 is used to store the fluid to be infused; one end of the first catheter 141 is connected to the first liquid storage box 131; the infusion unit includes a first infusion unit 151, and the first infusion unit 151 is used to drain the fluid to be infused in the first liquid storage box 131 through the first catheter 141 to the patient corresponding to the patient information; the controller 160 is connected to the infusion unit in communication, and the controller 160 is used to control the working state of the infusion unit according to the patient information; the input unit 170 is connected to the controller 160 in communication, and the input unit 170 is used to input the patient information.

[0060] In this embodiment, the first liquid storage box 131 is loaded with the fluid to be infused, and the patient information is input to the controller 160 through the input unit 170, and the controller 160 determines the infusion parameters according to the patient information. According to the judgment of the controller 160, the infusion unit is controlled to drain the fluid to be infused in the first liquid storage box 131, so that the fluid to be infused is drained to the patient corresponding to the patient information through the first catheter 141. The housing 110 plays a good protective role for the chamber fluid box 120, the first liquid storage box 131, the infusion unit and the controller 160 wrapped therein, and there is no need to worry about the infusion amount error or damage to the device due to the bumps and vibrations of the device when the patient moves with the device.

[0061] Specifically, taking the case of a parenteral nutrition patient providing self-infusion as an example, the nutrient solution is sealed in the first liquid storage box 131, and the patient information is input into the controller 160 through the input unit 170. The controller 160 determines the corresponding nutrient solution infusion information according to the patient information, and the controller 160 controls the infusion unit to perform the nutrient solution infusion operation according to the nutrient solution infusion information.

[0062] In some embodiments, Figure 2 As shown, in order to better utilize the cavity space of the fluid infusion device, and to meet some specific medical needs, different fluids to be infused need to be infused in the same time period, the fluid infusion device is also provided with a second infusion unit 152, a second liquid storage box 132 and a second conduit 142. The second liquid storage box 132 is fixed in the chamber fluid box 120; one end of the second conduit 142 is connected to the second liquid storage box 132, and the other end extends out of the housing 110; one end of the second infusion unit 152 is connected to the second liquid storage box 132 or the second conduit 142, and the second infusion unit 152 is used to drain the liquid in the second liquid storage box 132 through the second conduit 142 to the patient corresponding to the patient information; the second infusion unit 152 is in communication connection with the controller 160.

[0063] In this embodiment, different fluids to be infused are loaded into the corresponding first liquid storage box 131 and the second liquid storage box 132 respectively, and the patient information is input into the controller 160 through the input unit 170. The controller 160 determines the infusion information, and the infusion unit drains the fluids to be infused in the first liquid storage box 131 and the second liquid storage box 132 according to the infusion information, and drains the fluids to be infused through the corresponding first conduit 141 and the second conduit 142 to the patient corresponding to the patient information. Figure 2 The first infusion unit 151 shown, when the infusion unit is a structure such as a plunger, controls the plunger to move in the first liquid storage box 131 through the infusion information to push the fluid to be infused, and the first infusion unit 151 is connected to the first liquid storage box 131; Figure 2The second infusion unit 152 shown, when the infusion unit is a structure such as a peristaltic pump or a roller pump, guides the fluid to be infused to drain through the pump body, and the second infusion unit 152 is connected to the second catheter 142. It should be noted that the corresponding relationship between the structure of the infusion unit and the liquid storage box in the infusion unit is not limited, wherein the specific structure of the infusion unit can be a plunger, a peristaltic pump or a roller pump, etc., and the number of liquid storage boxes is not limited, and can include the first liquid storage box 131 and the second liquid storage box 132, etc.

[0064] In some embodiments, taking a parenteral nutrition patient with diabetes as an example, the patient's blood sugar data is constantly monitored while the parenteral nutrition solution is infused, and the infusion of insulin is arranged according to the blood sugar situation. The nutrient solution and insulin are sealed in the first liquid storage box 131 and the second liquid storage box 132 respectively, and the patient information is input to the controller 160 through the input unit 170. The controller 160 determines the infusion information of the first liquid storage box 131 containing the nutrient solution according to the patient information, and the controller 160 controls the first infusion unit 151 according to the infusion information to complete the infusion operation that meets the infusion information. The blood sugar index is continuously monitored during the process, and the blood sugar index is sent to the controller 160. The controller 160 controls the second infusion unit 152 according to the level of the blood sugar index, thereby controlling the second liquid storage box 132 containing insulin to complete the corresponding infusion of insulin, so as to balance the patient's physical state. When the patient's blood sugar suddenly rises, the infusion amount of insulin is quickly increased by a separate insulin infusion, while the normal infusion of the nutrient solution is not affected. When the infusion is separated, the blood sugar needs to be monitored more closely to avoid the blood sugar fluctuation caused by the mismatch between the insulin infusion speed and the nutrient solution infusion speed. It is understandable that for diabetic patients, considering that insulin infusion is more refined, the second infusion unit 152 can be an insulin pump, which receives the control signal of the controller 160, obtains insulin from the second liquid storage box 132, and can continuously deliver insulin to the patient through the second catheter 142 to achieve insulin infusion.

[0065] In some embodiments, Figure 3 As shown, in order to meet the mixed infusion requirements during medical procedures, the fluid infusion device is also provided with a three-way catheter 180 and a third catheter 143, one end of the three-way catheter 180 is connected to the third catheter 143, and the other two ends of the three-way catheter 180 are respectively connected to the first catheter 141 and the second catheter 142 in the cavity.

[0066] In this embodiment, different fluids to be infused are loaded into the corresponding first liquid storage box 131 and second liquid storage box 132 respectively, and the patient information is input into the controller 160 through the input unit 170. The controller 160 determines the infusion information, and the infusion unit is used to drain the fluids to be infused in the first liquid storage box 131 and second liquid storage box 132 according to the infusion information, and drain the fluids to be infused into the first conduit 141 and second conduit 142, and the fluids to be infused in the first conduit 141 and second conduit 142 are collected and merged through the three-way conduit 180, and the merged fluids to be infused are drained to the patient corresponding to the patient information through the third conduit 143. The three-way conduit 180 is fixed on the housing 110, and the first conduit 141 and second conduit 142 are connected to the three-way conduit 180 in the cavity, and do not need to be extended to the outside of the housing 110, so as to avoid the connection interface between the first conduit 141 and second conduit 142 and the three-way conduit 180 from being exposed outside the box, and to avoid the fluids to be infused from being contaminated through the connection port.

[0067] Specifically, take a parenteral nutrition patient with diabetes as an example. Due to the high glucose content in the parenteral nutrition solution, it is easy to cause blood sugar to rise after being injected into the human body. The main function of insulin is to regulate blood sugar, keep it within the normal range, and avoid hyperglycemia and its related complications. Insulin can be infused synchronously with the nutrient solution through the same intravenous access. Generally, insulin is added to the nutrient solution bag, mixed evenly and then infused. The advantage of this method is that the operation is relatively simple, and insulin can enter the body evenly with the nutrient solution, which is conducive to stabilizing blood sugar, but the input amount is fixed, and the infusion amount cannot be adaptively adjusted according to the body condition parameters during the input process. A better choice is to set a three-way catheter 180 and a third catheter 143 when synchronous infusion is required. The nutrient solution of the first catheter 141 and the insulin of the second catheter 142 are mixed at the three-way catheter 180, and then flow through the third catheter 143 and drain to the patient corresponding to the patient information, so as to complete the synchronous infusion. In this process, the infused nutrient solution or insulin can be regulated in real time by the obtained body condition parameters, which is convenient for coping with different emergencies.

[0068] In some embodiments, when the infusion unit is a drainage device such as a peristaltic pump, an insulin pump or a roller pump connected to a catheter, the infusion unit and the corresponding catheter portion connected to the infusion unit can be arranged in a cavity within the shell 110, which effectively reduces the overall cost and complexity of the device while being convenient for users to carry and use.

[0069] In some embodiments, in order to ensure the storage conditions of the fluid to be infused and control the storage temperature, the fluid infusion device is further provided with a temperature control box and a temperature sensor, the temperature control box is fixed in the chamber fluid box 120, the temperature sensor is used to monitor the real-time temperature in the chamber fluid box 120 in real time, and the controller 160 is used to control the working state of the temperature control box according to the real-time temperature. When the temperature sensor detects that the temperature exceeds the threshold, physical cooling can be achieved by placing ice cubes in the temperature control box, so that the overall temperature of the fluid infusion device is controlled within the temperature threshold.

[0070] In some embodiments, in order to control the storage temperature of the fluid to be infused in the chamber fluid box, the fluid infusion device is also provided with a temperature control box and a temperature sensor, and liquid nitrogen is optionally sealed in the temperature control box. When the temperature sensor detects that the temperature exceeds the threshold, a trace amount of liquid nitrogen is released, and the temperature of the fluid infusion device is reduced by absorbing heat energy by vaporization of liquid nitrogen, so as to be controlled within the temperature threshold. Specifically, taking a parenteral nutrition patient with diabetes as an example. In order to keep the effectiveness of nutrient solution and insulin and reduce the risk of contamination, it is necessary to control the first liquid storage box 131 storing nutrient solution and the second liquid storage box 132 storing insulin to be maintained at about 25-30 degrees. Such a temperature is not easy to deteriorate the fluid to be infused, and the patient will not feel uncomfortable due to the excessively high or low temperature of the fluid to be infused during the infusion process. The temperature sensor is the front-end monitoring component of the entire temperature control system, which is placed in the chamber fluid box 120 near the liquid storage box to sense the temperature of the surrounding environment in real time. When the ambient temperature changes, the temperature sensor converts the temperature signal into an electrical signal, and the temperature sensor transmits the analog electrical signal to the controller 160, through the microprocessor of the controller 160, which has a special interface to receive the signal from the temperature sensor. After receiving the signal from the temperature sensor, the controller 160 processes the signal, first converting the analog signal into a digital signal, and the converted digital signal can be accurately identified and processed by the controller 160; then the controller 160 compares the digital temperature signal with the preset temperature threshold; when the controller 160 determines that the temperature exceeds the threshold, it sends a control signal to the temperature control box, which can be a digital pulse signal or a level signal, and its purpose is to activate the liquid nitrogen release mechanism in the temperature control box. There is a special liquid nitrogen storage and release device in the temperature control box, which includes a small liquid nitrogen storage tank, a solenoid valve and some pipes. When the control signal of the controller 160 arrives, the solenoid valve will open, so that the liquid nitrogen in the liquid nitrogen storage tank is released into the space around the liquid storage box through the pipe. Liquid nitrogen absorbs a lot of heat during the vaporization process, thereby reducing the temperature around the liquid storage box. At the same time, the temperature sensor will continue to monitor the temperature change and feed back the new temperature signal to the controller 160. The controller 160 will make a judgment based on the new temperature signal fed back by the temperature sensor. If the temperature is still higher than the threshold, the controller 160 will continue to let the temperature control box release liquid nitrogen; if the temperature has dropped below the threshold, the controller 160 will send a signal to close the solenoid valve of the temperature control box and stop the release of liquid nitrogen. This feedback adjustment process is a dynamic, real-time process that can accurately control the temperature around the liquid storage box to ensure that the nutrient solution and insulin are always within the appropriate storage temperature range.

[0071] In some embodiments, in order to obtain the real-time status of the patient, the input unit 170 of the fluid infusion device is also provided with a physical condition monitoring unit. The physical condition monitoring unit is connected to the controller 160 for obtaining the physical condition data of the patient. The physical condition monitoring unit can be a continuous monitoring sensor device, which can emergency-control the infusion unit according to the physical condition value, so as to achieve the effect of timely suppressing or alleviating the patient's symptoms. The physical condition monitoring unit can be connected to the controller 160 in a wired or wireless form.

[0072] Specifically, take diabetic patients as an example. In order to monitor the patient's blood sugar in real time, a blood sugar detection unit can be set up. The blood sugar detection unit can use a continuous blood sugar monitoring sensor to monitor the glucose concentration and continuously monitor the blood sugar level. The sensor is placed in the arm or abdomen of the infusion subject, and the glucose concentration in the interstitial fluid is monitored through a microprobe; or a non-invasive blood sugar monitoring sensor is used, such as using spectroscopy technology to penetrate the skin through a specific wavelength of light (such as near-infrared light), and inferring the blood sugar concentration by analyzing the absorption and reflection characteristics of light, or by ultrasonic or electromagnetic technology, the reflection and propagation characteristics of ultrasonic waves are used to monitor the blood sugar concentration to measure the blood sugar level without piercing the skin to measure the patient's blood sugar.

[0073] In some embodiments, in order to timely know the amount of fluid to be infused in the first liquid storage box 131 or the second liquid storage box 132 so as to replenish or replace it in time, a liquid level sensor is provided in both the first liquid storage box 131 and the second liquid storage box 132, and an alarm unit is also provided in the cavity of the housing 110. The liquid level sensor is used to monitor the real-time liquid level value in the first liquid storage box 131 or the second liquid storage box 132, and the controller 160 controls the working state of the alarm unit according to the real-time liquid level value. Specifically, when the liquid level sensor detects that the liquid level of the fluid to be infused in the first liquid storage box 131 or the second liquid storage box 132 is lower than the liquid level threshold, the controller 160 sends a signal to the alarm unit according to the real-time liquid level value, and the alarm unit displays a low liquid level prompt to the patient by making a sound, displaying a prompt interface, or flashing a light at a specific frequency, so as to avoid the patient being unable to replenish the fluid to be infused in time when going out.

[0074] In some embodiments, the alarm unit may sound an alarm based on the results of the body condition monitoring unit. When the body condition monitoring unit detects abnormal values, the alarm unit sounds an alarm.

[0075] In some embodiments, in order to facilitate the replacement of the type of fluid to be infused or increase the amount of fluid to be infused, the first liquid storage box 131 and the second liquid storage box 132 of the chamber fluid box 120 of the fluid infusion device are detachable structures, and the type of fluid to be infused or the amount of fluid to be infused is changed or increased by replacing the first liquid storage box 131 or the second liquid storage box 132, so that the fluid to be infused does not contact the outside world, reducing the possibility of contamination. In this case, it is not convenient to set the liquid level sensor in the first liquid storage box 131 or the second liquid storage box 132, but to set a photoelectric liquid level sensor in the chamber fluid box 120. A near-infrared light-emitting diode and a photosensitive receiver are arranged on the inner wall of the chamber fluid box 120. When the fluid to be infused submerges the lens of the photoelectric liquid level switch, the light is refracted into the fluid to be infused, so that the receiver cannot receive or can only receive a small amount of light. If there is no or very little fluid to be infused, the light emitted by the light-emitting diode is directly reflected from the lens back to the receiver. The photoelectric liquid level sensor obtains the liquid level status by sensing this change in working condition, so that the patient can replenish or replace the fluid to be infused in time.

[0076] In some embodiments, due to the particularity of the movable fluid infusion device, the fluid infusion device may tilt during movement, or the first liquid storage box 131 or the second liquid storage box 132 may shake during movement, which may cause the liquid level sensor to misjudge and cause the alarm unit to transmit erroneous information. A gyroscope sensor is provided in the chamber fluid box 120. The real-time posture of the fluid infusion device is determined by the gyroscope sensor. Only when the fluid infusion device is in a vertical upright state or a stable equilibrium state can the liquid level of the first liquid storage box 131 or the second liquid storage box 132 be determined by the liquid level sensor. When the measured liquid level is lower than the liquid level threshold, the alarm unit issues a prompt.

[0077] In some embodiments, when the physical condition monitoring unit of the fluid infusion device detects that the patient's physical condition is abnormal, in addition to promptly controlling the infusion unit to infuse the patient, the controller 160 will also promptly control the alarm unit to issue a prompt to inform the patient, so that the patient can promptly know the current physical condition, maintain a suitable posture and stop the current physical labor to avoid further deterioration.

[0078] In some embodiments, the input unit 170 of the fluid infusion device is provided with a display interface and an input key. The display interface is used to display patient information and prompt information, and the input key is used to input patient information into the controller 160. The display interface may also be a touch screen, and the patient or medical staff may input the corresponding patient information on the touch screen, so that the controller 160 may automatically determine the infusion parameters for the patient information according to the input patient information. The input unit 170 may be fixed on the housing 110, or may be connected to the housing 110 by wire or wireless means.

[0079] In some embodiments, the input unit 170 of the fluid infusion device may also be provided with a voice input unit, and after identity authentication is completed, the microphone captures the voice, converts the captured voice into an executable command through voice recognition technology, and inputs the executable command into the controller 160. The controller 160 may automatically determine the infusion parameters for the patient information according to the executable command.

[0080] In some embodiments, the input unit 170 of the fluid infusion device may also be provided with a wireless receiving module, and the patient or medical staff may input the patient information through a mobile device, and transmit the patient information to the input unit 170 through a wireless transmission method such as WIFI or Bluetooth, and the input patient information is pre-processed and then input to the controller 160. The controller 160 automatically determines the infusion parameters for the patient information according to the pre-processed patient information.

[0081] Figure 4 is an optional flow chart of a control method for a fluid infusion device provided in an embodiment of the present application. Figure 4 The control method is applied to the controller 160 of the fluid infusion device, and the control method includes but is not limited to steps S401 to S403:

[0082] Step S401: Acquire patient information of an input unit;

[0083] Step S402: acquiring target infusion information of the patient corresponding to the patient information through a target mapping relationship table according to the patient information;

[0084] Step S403: Control the working process of the infusion unit according to the target infusion information.

[0085] In some embodiments, the patient or medical staff inputs the patient information into the input unit 170, which is processed into readable data and transmitted to the controller 160 by the input unit 170. The patient information is matched with the patient's target infusion information through the target mapping relationship table, and the target infusion information of the patient corresponding to the patient information is obtained. The corresponding infusion unit is controlled according to the target infusion information, and the infusion unit drains the infused fluid through the catheter to the patient corresponding to the patient information, wherein the target mapping relationship table is stored in the controller 160 based on prior experience.

[0086] In some embodiments, in step S401, the patient information is determined according to the type of illness, including but not limited to height, weight, work physical type, breakfast, lunch and dinner time range and age. It can also be screened according to the prompt information of the input unit 170, such as infusion by time or infusion by schedule. Among them, infusion by time is to divide the corresponding time intervals of a day according to the determined number of times, and start the infusion at the corresponding infusion time; infusion by schedule is to select the infusion time, and start the infusion according to the set corresponding time. The specific time can be manually modified according to the patient or medical staff.

[0087] In some embodiments, Figure 5 yes Figure 4 Flowchart of step S402 in FIG. Figure 4 Step S402 includes but is not limited to steps S501 to S503:

[0088] Step S501: Acquire patient information characteristics and infusion key point characteristics according to patient information;

[0089] Step S502: Obtaining a target mapping relationship table through patient information features;

[0090] Step S503: Obtain target infusion information through the target mapping relationship table according to the infusion key point features.

[0091] In some embodiments, when the fluid infusion device is only provided with the first liquid storage box 131, in order to accurately obtain the target infusion information, the patient information characteristics are determined through the patient information, and the corresponding target mapping relationship table is determined by screening the patient information characteristics according to the target mapping relationship table stored in the controller 160; then the infusion key point characteristics are obtained through the patient information, and the key features corresponding to the infusion key point characteristics are retrieved from the table through the target mapping relationship table, and the target infusion information is obtained through the integration of the key features. Among them, the patient information characteristics refer to the characteristics of the type of fluid to be infused corresponding to the condition reflected in the patient information; the infusion key point characteristics refer to the key features directly associated with the target infusion information from the target mapping relationship table corresponding to the type of fluid to be infused.

[0092] In other embodiments, Figure 6 yes Figure 4 Flowchart of step S402 in FIG. Figure 4 Step S402 includes but is not limited to steps S601 to S605:

[0093] Step S601: Acquire patient information characteristics and infusion key point characteristics according to patient information;

[0094] Step S602: acquiring a first mapping relationship table and a second mapping relationship table according to patient information characteristics, wherein the target mapping relationship table includes the first mapping relationship table and the second mapping relationship table;

[0095] Step S603: acquiring first target infusion information through a first mapping relationship table according to the infusion key point features;

[0096] Step S604: acquiring second target infusion information through a second mapping relationship table according to the first target infusion information and the infusion key point features;

[0097] Step S605: combining the first target infusion information and the second target infusion information to obtain target infusion information.

[0098] In this embodiment, when the fluid infusion device is provided with a first liquid storage box 131 and a second liquid storage box 132, it means that there are two fluids to be infused, namely, a first fluid to be infused and a second fluid to be infused. The first mapping relationship table and the second mapping relationship table corresponding to the first fluid to be infused and the second fluid to be infused are screened out from the numerous target mapping relationship tables stored in the controller 160 through the patient information characteristics, and the target mapping relationship table includes the first mapping relationship table and the second mapping relationship table. The corresponding first target infusion information is retrieved in the first mapping relationship table through the infusion key point feature. When the first fluid to be infused and the second fluid to be infused have a medicinal property association, such as insulin and nutrient solution for diabetic patients with parenteral nutrition, for insulin infusion, it is necessary to refer to the historical insulin infusion situation and pay attention to the patient's nutrient solution infusion situation, and regulate the insulin infusion according to the patient's comprehensive blood sugar data, thereby suppressing the abnormal increase in blood sugar caused during the nutrient solution infusion process. Therefore, the second target infusion information is obtained through the second mapping relationship table in combination with the infusion key point feature through the first target infusion information. The first target infusion information and the second target infusion information are combined to obtain target infusion information, and then the first target infusion information and the second target infusion information are respectively transmitted to the corresponding first infusion unit 151 and the second infusion unit 152 through the controller 160 for infusion operation.

[0099] In some embodiments, in step S403, the acquired target infusion information is screened, and the target infusion information includes target infusion volume information, target infusion time information, and target infusion speed information. Among them, the target infusion time information refers to the frequency and specific time of infusion within a day, the target infusion volume information refers to the infusion volume in each infusion process, and the target infusion speed information refers to the infusion speed of each infusion process determined according to the properties of the fluid to be infused. The target infusion volume information and the target infusion speed information are transmitted to the corresponding infusion unit according to the target infusion time information, and the infusion unit drains the fluid to be infused through the catheter to the patient corresponding to the patient information according to the target infusion volume information and the target infusion speed information.

[0100] In some embodiments, the fluid infusion device is continuously connected to the patient corresponding to the patient information through a catheter. Or before reaching the target infusion time information, the fluid infusion device notifies the patient through an alarm unit to connect the catheter on the fluid infusion device to the patient, wait for the fluid infusion device to deliver the fluid to be infused at the time corresponding to the target infusion time information, and then separate the catheter after the infusion is completed, thereby reducing the impact on daily activities.

[0101] In some embodiments, a parenteral nutrition patient with diabetes is taken as an example. Patient information includes nutrient solution infusion information and blood sugar control information. The nutrient solution infusion information includes nutrient solution infusion time, nutrient solution infusion frequency and nutrient solution infusion parameters. The blood sugar control information includes blood sugar monitoring time, blood sugar monitoring frequency and insulin infusion parameters. For nutrient solution infusion information, the nutrient solution infusion time, that is, the specific time arrangement for supplementary nutrient solution infusion, includes the daily infusion start and end time, and the infusion time point in a specific treatment stage, wherein each infusion has its corresponding nutrient solution infusion time. Nutrient solution infusion parameters, that is, describe the specific settings and conditions of nutrient solution infusion, including the infusion speed and the ratio of infused nutrients. For blood sugar control information, the blood sugar monitoring time, that is, the specific time for measuring blood sugar level, is a fixed time every day, determined according to the patient information of the infusion object, and adjusted in combination with the nutrient solution infusion information or other drug usage; blood sugar monitoring frequency, that is, the frequency of blood sugar level measurement, can be measured multiple times a day or more frequently monitored in specific circumstances according to the patient's health status and treatment goals, so as to adjust the treatment plan in time; insulin infusion parameters, that is, the specific settings and conditions of insulin infusion, including insulin dosage, infusion schedule, infusion speed, etc. Blood sugar history information includes the patient's historical blood sugar level records, insulin usage, eating habits, etc., and collecting blood sugar history information helps to fully understand the patient's blood sugar control needs. The controller 160 uses the second mapping relationship table to query and determine the blood sugar control information suitable for the patient in combination with the determined nutrient solution infusion information and the collected blood sugar history information. The second mapping relationship table includes the matching relationship between adjusting the blood sugar monitoring time, frequency and insulin infusion parameters according to the nutrient solution infusion information and the blood sugar history. In combination with the patient's nutrient solution infusion information and blood sugar history information, the controller 160 automatically configures a blood sugar management plan that is more suitable for the patient. The first mapping relationship table and the second mapping relationship table are preset and stored in the controller 160; the first mapping relationship includes the correspondence between different basic information and the nutritional input information of each range, and the second mapping relationship includes the correspondence between different nutrient solution infusion information and blood sugar history information and the blood sugar control information of each range. For example, the patient information controller 160 automatically obtains information such as BMI value and labor activity intensity, and obtains Figure 7The first mapping relationship table shown shows the daily energy supply (kcal / kg) of adult diabetic patients according to the table. The daily energy supply of the patient can be determined from the table, thereby acting on the first infusion unit 151. According to the blood sugar history information, the patient types are divided into: normal patients (i.e., no history of diabetes, normal patients do not infuse insulin, and the daily energy can be designed to be 25-30 kcal / kg / day), strict control of diabetes, general control of diabetes, and loose control of diabetes. The range of blood sugar control according to the patient type can be as follows:

[0102] Strict: fasting or pre-meal (i.e. before nutrient solution infusion) blood sugar is controlled at 4.4-6.1 mmol / L, and 2 hours post-meal (i.e. 2 hours after nutrient solution infusion) or random blood sugar is controlled at 6.1-7.8 mmol / L;

[0103] Generally: fasting or pre-meal (i.e. before nutrient solution infusion) blood sugar is controlled at 6.1-7.8 mmol / L, and 2 hours after meal (i.e. 2 hours after nutrient solution infusion) or random blood sugar is controlled at 7.8-10.0 mmol / L;

[0104] Loose: fasting or pre-meal (i.e. before nutrient solution infusion) blood sugar is controlled within 7.8-10.0 mmol / L, and 2 hours after meal (i.e. 2 hours after nutrient solution infusion) or random blood sugar is controlled within 7.8-13.9 mmol / L;

[0105] The above blood sugar control range is combined with Figure 8 As shown, Figure 8 The process of the controller 160 determining the nutrient solution infusion information and the blood sugar control information according to the patient information includes the following steps:

[0106] Step a: Daily energy requirement determination source: 1. Patient's height, weight (or age) and other information; 2. Labor activity intensity;

[0107] Step b, average energy per meal per day: based on the daily energy, calculate the energy according to three meals a day (or other methods);

[0108] Step c, determine the timing of energy feeding (infusion) at each meal: 1. Feed according to the interval between each meal; 2. Feed according to the specific time of each meal;

[0109] Step d, determine blood sugar control information: 1. Blood sugar control range before and after meals (i.e. blood sugar range standard value); 2. Blood sugar measurement time and frequency: strict: every 1 minute, general: every 5 minutes, loose: every 10 minutes. In this way, combined with patient information and mapping relationship table, provide patients with personalized nutrient solution infusion and blood sugar infusion plans with high efficiency.

[0110] When the blood sugar monitoring result meets the blood sugar monitoring standard value, the nutrient solution infusion operation is performed according to the determined nutrient solution infusion information. Specifically, the following steps are included: when the blood sugar monitoring result is monitored within the first preset time before the nutrient solution infusion time, and the blood sugar monitoring result is within the blood sugar standard value range, the nutrient solution infusion unit is controlled to perform the nutrient solution infusion operation within the nutrient solution infusion time. Among them, the blood sugar monitoring time is set to a period of time before the nutrient solution infusion time, that is, the first preset time, and a period of time after the nutrient solution infusion time, that is, the second preset time. The first preset time and the second preset time are determined according to actual application or prior data, wherein the first preset time is before the nutrient solution infusion time is about to enter, and the second preset time is after the nutrient solution infusion time. For example, when the blood sugar monitoring result 5 minutes before the meal is within the blood sugar standard value range, the controller 160 controls the infusion unit corresponding to the nutrient solution to perform the nutrient solution infusion operation at the nutrient solution infusion time corresponding to the first preset time. By means of pre-meal blood sugar monitoring, when the corresponding blood sugar standard value range is met, the corresponding nutrient solution infusion operation is performed, which can more effectively manage the patient's metabolic state and provide safer and more effective nutrient solution infusion support.

[0111] In some embodiments, a parenteral nutrition patient with diabetes is taken as an example. The control method of the controller 160 also includes delayed infusion to balance the user's blood sugar level. The controller 160 controls the nutrient solution infusion operation of the first infusion unit 151 corresponding to the nutrient solution according to the infusion information of the nutrient solution and the blood sugar monitoring result. Specifically, when the blood sugar monitoring result is monitored within the first preset time before the nutrient solution infusion time, and the blood sugar monitoring result is greater than the maximum value of the blood sugar standard value range, the nutrient solution infusion time is delayed according to the preset delay rule to obtain the delay time; the blood sugar monitoring unit is controlled to perform blood sugar monitoring until the blood sugar monitoring result is within the blood sugar standard value range, and the nutrient solution infusion operation of the nutrient solution infusion unit is controlled within the delay time. It is understandable that if the blood sugar value monitored before a meal is greater than the corresponding blood sugar standard value range before the meal, it is considered that the current patient's blood sugar value is too high. If the nutrient solution infusion operation is still performed within the corresponding nutrient solution infusion time, the already high blood sugar level will be further increased, thereby causing the patient's blood sugar to be too high. Based on the blood sugar monitoring results, this embodiment delays the infusion of nutrient solution and, during the delay process, controls the body condition monitoring unit in real time to perform blood sugar monitoring, so as to achieve real-time adjustment of the nutrient solution infusion process, thereby further stabilizing the patient's blood sugar level.

[0112] In certain embodiments, take the parenteral nutrition patient suffering from diabetes as an example. The control mode of controller 160 also includes reducing the patient's blood sugar by real-time insulin infusion. Specifically, when the blood sugar monitoring result is within the first preset time, and the blood sugar monitoring result is greater than the maximum value of the blood sugar standard value range, the controller 160 controls the insulin infusion operation of the second infusion unit 152 corresponding to insulin in real time. Exemplarily, the controller 160 calculates the insulin dosage and the corresponding infusion rate according to the blood sugar monitoring result, sends the calculated insulin dosage and the corresponding infusion rate to the second infusion unit 152, and performs insulin infusion operation according to the insulin dosage and the corresponding infusion rate. Based on the patient's blood sugar situation during the nutrient solution infusion process, the method of insulin infusion is used to help reduce the user's blood sugar risk.

[0113] In some embodiments, a parenteral nutrition patient with diabetes is taken as an example. The control method of the controller 160 also includes real-time adjustment when the blood sugar level is less than the minimum value of the standard blood sugar value range. Specifically, the controller 160 controls the nutrient solution infusion operation of the first infusion unit 151 according to the nutrient solution infusion information and the blood sugar monitoring result. When the blood sugar monitoring result is monitored within the first preset time before the nutrient solution infusion time, and the blood sugar monitoring result is less than the minimum value of the standard blood sugar value range, the first infusion unit 151 corresponding to the nutrient solution is controlled in real time to perform the nutrient solution infusion operation.

[0114] In some embodiments, a parenteral nutrition patient with diabetes is taken as an example. The control method of the controller 160 also includes adjusting the user's blood sugar level by postprandial blood sugar monitoring. The controller 160 controls the insulin infusion operation of the insulin infusion unit according to the blood sugar monitoring result. Specifically, when the blood sugar monitoring result is monitored within the second preset time after the nutrient solution infusion time, and the blood sugar monitoring result is greater than the maximum value of the blood sugar standard value range, the second infusion unit 152 is controlled to perform the insulin infusion operation; after controlling the insulin infusion operation, the blood sugar monitoring unit is controlled to perform blood sugar monitoring to obtain a new blood sugar monitoring result; if the new blood sugar monitoring result is greater than the maximum value of the blood sugar standard value range, the insulin infusion operation of the insulin infusion unit is continued to be controlled until the new blood sugar monitoring result is within the blood sugar standard value range. Optionally, the second preset time is after the meal, and the parenteral nutrition solution enters the blood directly through the vein, but the body still needs a certain amount of time to metabolize and utilize these nutrients. Usually, the blood sugar level reaches a peak within a period of time after the infusion. By monitoring blood sugar for a period of time after the infusion, the effect of the nutrient solution infusion on blood sugar is observed, thereby identifying whether insulin needs to be adjusted. When the blood sugar monitoring result after a meal is greater than the maximum value of the blood sugar standard value range, the infusion operation of insulin is immediately controlled, and the nutrient solution infusion is not performed. If the blood sugar value is still higher than the corresponding blood sugar standard value range, it is infused again until the monitoring result returns to the corresponding blood sugar standard value range. Therefore, the blood sugar level of the user can be effectively adjusted by monitoring blood sugar after a meal. When the blood sugar monitoring result is monitored within the second preset time after the nutrient solution infusion time, if the new blood sugar monitoring result is within the blood sugar standard value range, the next nutrient solution infusion time is waited for, and the first infusion unit 151 corresponding to the nutrient solution is controlled to perform the nutrient solution infusion operation within the next nutrient solution infusion time. More specifically, when the new blood sugar monitoring result is within the corresponding blood sugar standard value range, the controller 160 stops controlling the infusion operation of the insulin infusion unit insulin, and waits for the next nutrient solution infusion time corresponding to the nutrient solution infusion information, and infuses the user with nutrient solution again, thereby achieving the purpose of nutrient solution infusion while ensuring the patient's blood sugar balance.

[0115] In some embodiments, the control method of the controller 160 also includes controlling the nutrient solution infusion operation of the first infusion unit 151 according to the nutrient solution infusion information and the blood glucose monitoring result. Specifically, when the blood glucose monitoring result is monitored within the second preset time after the nutrient solution infusion time, and the blood glucose monitoring result is less than the minimum value of the blood glucose standard value range, a nutrient supplement confirmation message is generated, and the nutrient supplement confirmation information is used to indicate whether the nutrient solution infusion operation is currently being performed and the corresponding supplementary nutrient solution infusion parameters; the control input unit 170 transmits the nutrient solution supplement confirmation message to the alarm unit to inform the patient; the alarm unit controls the first infusion unit 151 corresponding to the nutrient solution to perform the nutrient solution infusion operation according to the feedback information of the nutrient solution supplement confirmation fed back by the input unit 170. In this embodiment, considering that the patient may have hypoglycemia after the nutrient solution infusion, this situation may be that the patient has basically completed the metabolism of the infused nutrient solution, and the patient's blood sugar can be balanced by increasing nutrient intake. However, since the nutrient solution infusion information is determined by the patient's information, if the nutrient solution infusion is automatically supplemented, it will lead to overnutrition of the patient, resulting in a series of adverse health effects, such as automatic supplementation of too much nutrition, resulting in an increase in blood sugar levels, or excessive nutrient intake may increase the metabolic burden on the liver and kidneys. Based on such adverse effects, when the postprandial blood sugar value range is low, by generating a nutrient supplement confirmation message, the patient actively confirms and adjusts, thereby supplementing the nutrient solution infusion, which can effectively optimize the patient's nutritional management and overall blood sugar level.

[0116] In some embodiments, Fig. 9 As shown, it is a schematic diagram of the infusion of nutrient solution and insulin for a parenteral nutrition patient with diabetes. The controller 160 controls the first infusion unit 151 corresponding to the nutrient solution to perform the nutrient solution infusion operation before the nutrient solution infusion operation, or sends a control signal to the body condition monitoring unit to perform blood sugar monitoring after a meal, and obtains the blood sugar monitoring result.

[0117] Based on the blood glucose monitoring results before meals, fluid infusion situations can include the following 01-03 situations:

[0118] 01. When the blood sugar monitoring result is within the current blood sugar standard value range, the nutrient solution infusion can be started normally, that is, the nutrient solution infusion unit is controlled to perform the nutrient solution infusion operation at the corresponding nutrient solution infusion time according to the nutrient solution infusion information;

[0119] 02. When the blood sugar monitoring result is lower than the minimum value of the range, start the nutrient solution infusion immediately;

[0120] 03. When the blood sugar measurement result is higher than the maximum value of the range, immediately infuse insulin and delay the infusion of nutrient solution until the monitoring result returns to the range and then start the infusion of nutrient solution again.

[0121] Based on the blood glucose monitoring results after a meal, fluid infusion situations can include the following 04-06 situations:

[0122] 04. When the blood sugar monitoring result is within the standard blood sugar value range, the nutrient solution infusion is not normally performed until the nutrient solution infusion time is reached again;

[0123] 05. If the blood sugar level is still higher than the maximum value of the range, immediately infuse insulin without infusing nutrient solution; if the blood sugar level is still higher than the range 2 hours after infusion, infuse again until the blood sugar monitoring result returns to the range;

[0124] 06. When the blood sugar level is lower than the minimum value of the range, the controller 160 will feed back a nutritional supplement confirmation message to the patient, and the patient will decide whether additional nutritional solution infusion is needed. The nutritional supplement can be infused at 50% of the normal amount per meal, which can be adjusted by the patient.

[0125] In some embodiments, Fig.10 As shown, a method for infusing a parenteral nutrition patient with diabetes through a fluid infusion device comprises the following steps:

[0126] Step S1001: determining nutrient solution infusion information and blood sugar control information according to patient information;

[0127] Step S1002: According to the blood sugar control information, the body condition monitoring unit is controlled to perform blood sugar monitoring, and according to the blood sugar monitoring result, the second infusion unit corresponding to the insulin is controlled to perform an insulin infusion operation;

[0128] Step S1003: According to the infusion information of the nutrient solution and the blood sugar monitoring result, the first infusion unit corresponding to the nutrient solution is controlled to perform the nutrient solution infusion operation.
