Description

Technical Field

[0001] This invention relates to the technical field of controlled infusion bag dispensing in clinical medicine, and in particular to a mesh-type pressurized infusion system, control method, device, equipment, and medium. Background Technology

[0002] In clinical medicine, especially in emergency situations, surgery, trauma resuscitation, and blood transfusions, it is often necessary to rapidly infuse patients with large amounts of medical fluids, such as saline, plasma substitutes, and blood products. To achieve rapid infusion, a non-elastic gas-filled bag is usually placed over the infusion bag. A manually operated balloon connected to the gas-filled bag is repeatedly squeezed to inflate it, using the gas pressure to compress the infusion bag and accelerate the delivery of the medication. This entire process requires continuous manual operation and monitoring by medical staff, making it impossible for them to perform other tasks and resulting in a significant waste of valuable human resources. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a mesh-type pressurized infusion system that can automatically squeeze the infusion bag and adjust the squeezing force in real time to adapt to actual needs, thereby reducing the required human resource costs.

[0007] The present invention also proposes a computer-readable storage medium.

[0008] In a first aspect, one embodiment of the present invention provides a mesh-type pressurized infusion system, the pressurized infusion system comprising: a mesh pressurization module, a dual-modal detection module, and a controller. The mesh pressurization module includes a mesh, an air bladder, and an air pump. The mesh is used to wrap an infusion bag, and the air bladder is disposed in the interlayer of the mesh. The air bladder is connected to the air pump through a first pipeline. The air pump and the controller are integrated in an external control box. The dual-modal detection module includes a liquid level sensor and a pressure sensor. The liquid level sensor is disposed at the bottom of the inner side of the mesh and is attached to the infusion bag. The liquid level sensor detects the liquid level data of the infusion bag in real time. The pressure sensor is integrated in the control box and disposed inside the first pipeline. The pressure sensor detects the air pressure data inside the air bladder in real time. The controller is connected to the air pump, the pressure sensor, and the liquid level sensor. The controller controls the power of the air pump according to the liquid level data and the air pressure data.

[0009] The pressurized infusion system of this invention has at least the following beneficial effects: Medical staff place the infusion bag into a mesh bag, fix the mesh bag to the infusion stand, and, according to clinical infusion needs, set the air pressure setting value for the infusion bag via the operation buttons on the control box, and start the infusion switch. The controller controls the air pump to begin inflating, the air bag gradually expands, applying uniform pressure to the infusion bag, pushing the medication through the infusion set into the patient's body. Simultaneously, a liquid level sensor monitors the liquid level data of the infusion bag in real time, and a pressure sensor monitors the air pressure data inside the air bag in real time. The liquid level data and air pressure data... The data is synchronously transmitted to the controller, which executes a closed-loop control algorithm based on the liquid level and air pressure data to dynamically adjust the air pump power. That is, when the liquid level drops and the air pressure decreases, the air pump power is increased to replenish the gas. When the air pressure reaches the set value, inflation stops and the system enters a pressure holding state. If the air pressure exceeds the high pressure threshold, the pressure can be released by opening the pressure relief valve. When the infusion bag is completely infused and the liquid level sensor detects that the liquid level data is 0, the controller controls the air pump to stop running. The system can automatically squeeze the infusion bag and adjust the squeezing force in real time to adapt to actual needs, reducing the required human resource costs.

The terms "greater than," "less than," and "exceeding" should be understood as excluding the stated number, while the terms "above," "below," and "within" should be understood as including the stated number.

[0051] In clinical medicine, especially in emergency situations, surgery, trauma resuscitation, and blood transfusions, it is often necessary to rapidly infuse patients with large amounts of medical fluids, such as saline, plasma substitutes, and blood products. To achieve rapid infusion, a non-elastic gas-filled bag is usually placed over the infusion bag. A manually operated balloon connected to the gas-filled bag is repeatedly squeezed to inflate it, using the gas pressure to compress the infusion bag and accelerate the delivery of the medication. This entire process requires continuous manual operation and monitoring by medical staff, making it impossible for them to perform other tasks and resulting in a significant waste of valuable human resources.

[0052] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a mesh-type pressurized infusion system that can automatically squeeze the infusion bag and adjust the squeezing force in real time to adapt to actual needs, thereby reducing the required human resource costs.

[0053] Reference Figure 1 and Figure 2 , Figure 1 A schematic diagram of the pressurized infusion system in an embodiment of the present invention is shown. Figure 2A block diagram of a pressurized infusion system according to an embodiment of the present invention is shown. In some embodiments, the pressurized infusion system includes: a net bag pressurization module, a dual-modal detection module, and a controller. The net bag pressurization module includes a net bag 1, an air bag 104, and an air pump 8. The net bag 1 is used to wrap the infusion bag. The air bag 104 is arranged in the interlayer of the net bag. The air bag 104 is connected to the air pump 8 through a first pipeline 6. The air pump 8 and the controller 9 are integrated in an external control box 7. The dual-modal detection module includes a liquid level sensor 101 and a pressure sensor 102. The liquid level sensor 101 is located at the bottom of the inner side of the net bag 1 and is attached to the infusion bag. The liquid level sensor 101 detects the liquid level data of the infusion bag in real time. The pressure sensor 102 is integrated in the control box 7 and is located inside the first pipeline 6. The pressure sensor 102 detects the air pressure data in the air bag 104 in real time. The controller 9 is connected to the air pump 8, the pressure sensor 102, and the liquid level sensor 101. The controller 9 controls the power of the air pump 8 according to the liquid level data and the air pressure data.

[0054] Medical staff place the infusion bag into the mesh bag 1 and secure the mesh bag 1 to the infusion stand. Based on clinical infusion needs, the medical staff sets the pressure setting value for the air bag 104 using the operation buttons on the control box 9 and starts the infusion switch. The controller 9 controls the air pump 8 to begin inflating, and the air bag 104 gradually expands, applying uniform pressure to the infusion bag and propelling the medication through the infusion set into the patient's body. Simultaneously, the liquid level sensor 101 monitors the liquid level data of the infusion bag in real time, and the pressure sensor 102 monitors the air pressure data inside the air bag 104 in real time. The liquid level and air pressure data are synchronously transmitted to the controller. The controller 9 executes a closed-loop control algorithm based on liquid level and air pressure data to dynamically adjust the power of the air pump 8. That is, when the liquid level drops and the air pressure decreases, the power of the air pump 8 is increased to replenish the gas. When the air pressure reaches the set value, the inflation stops and the system enters a pressure holding state. If the air pressure exceeds the high pressure threshold, the pressure can be released by opening the pressure relief valve 3. When the infusion bag is completely infused, the liquid level sensor 101 detects that the liquid level data is 0, and the controller 9 controls the air pump 8 to stop running. It can automatically squeeze the infusion bag and adjust the squeezing force in real time to adapt to the actual needs, thereby reducing the required human resource costs.

[0055] It should be noted that in some embodiments, the mesh bag is made of polyester fiber, which is non-toxic, odorless, heat-resistant, corrosion-resistant, and easy to disinfect, meeting the hygiene standards for clinical medical supplies and avoiding adverse reactions when in contact with medication or patients. The mesh bag has an adjustable structure, with a cylindrical main body and an elastic drawstring at the top, allowing for flexible adjustment of tightness according to the height and diameter of the infusion bag. This ensures the mesh bag fits tightly against the surface of the infusion bag, preventing displacement or deformation during pressurization. Furthermore, the inner side of the mesh bag features a double-layer design. The inner layer is made of smooth, breathable fabric that directly contacts the infusion bag, reducing friction damage and facilitating the installation of the level sensor. A sealed interlayer between the outer and inner layers houses the air bladder. The edges of this interlayer are sealed to prevent air bladder displacement and ensure even pressure distribution to the infusion bag surface after inflation. A fixing buckle at the bottom of the mesh bag allows for secure attachment to the infusion stand hook, keeping the infusion bag vertical and preventing tilting during infusion that could affect level detection and pressurization.

[0056] The airbag is made of silicone, possessing excellent elasticity, sealing properties, and biocompatibility. It is odorless and non-irritating, inflates evenly without rupturing due to excessive pressure, making it suitable for clinical pressurization. The overall shape of the airbag matches the mesh bag's interlayer, forming a ring-shaped sleeve that fits snugly against the inner layer of the mesh bag, fully covering the sides of the infusion bag. A recessed groove at the bottom corresponds to the level sensor, preventing the airbag from obstructing the sensor and ensuring accurate data. A sealed interface at the bottom of the airbag connects to the air pump via a first conduit, employing a threaded seal design to prevent air leakage during inflation. An internal pressure buffer layer within the airbag mitigates the instantaneous pressure surge during air pump inflation, preventing damage to the infusion bag from excessive localized pressure, while also ensuring more even pressure distribution and a stable infusion rate.

[0057] The air pump is a miniature, silent DC air pump integrated into an external control box. It features small size, low noise, low power consumption, and high inflation efficiency, making it suitable for the quiet environment of clinical wards and minimizing disruption to patients' rest. The air pump's inflation power is adjustable, dynamically controlled by the controller based on air pressure and liquid level data. It can achieve functions such as slow inflation, stable pressure maintenance, and rapid depressurization, meeting the pressurization needs of different clinical infusion scenarios. The air pump is equipped with an overload protection device that automatically stops operation when the air pump has been running for too long, the current is too high, or the air pressure reaches the set upper limit, preventing damage to the air pump. Simultaneously, both the air inlet and outlet of the first pipeline are equipped with one-way valves to prevent backflow of gas and air from the air bladder, ensuring stable pressurization pressure. The connection between the air pump and the control box uses a shock-resistant fixing structure to reduce vibration during air pump operation and avoid affecting the normal operation of other components within the control box.

[0058] Reference Figure 1Furthermore, in some embodiments, the airbag is also connected to a pressure relief valve via a second pipeline, and the airbag is also connected to a manual balloon via a third pipeline. A control valve is provided in the third pipeline. The first pipeline includes a Y-shaped pipeline. The air inlet end of the first pipeline is connected to the airbag, and a first solenoid valve is provided at the air inlet end. The exhaust end of the first pipeline is connected to the external environment, and a second solenoid valve is provided at the exhaust end. The first solenoid valve and the second solenoid valve are integrated in a control box and connected to a controller.

[0059] The first, second, and third tubing lines are all made of silicone tubing, possessing excellent flexibility, sealing properties, and corrosion resistance, preventing rupture or leakage due to excessive inflation pressure. The first, second, and third tubing lines are threaded into the sealing interface of the inflator, with the other end passing through the control box housing and connecting to the air pump outlet. The interfaces between the first tubing and the air pump, the second tubing and the pressure relief valve, and the third tubing and the manual balloon are all sealed with sealant to ensure a tight connection. Additionally, a pressure sensor mounting position is provided at the end of the first tubing near the control box, allowing the pressure sensor to directly detect the gas pressure within the tubing and reduce errors during pressure transmission. A small pressure relief valve is installed in the middle of the tubing, connected to the controller. When the gas pressure exceeds the set upper limit, the pressure relief valve opens to release excess gas, ensuring the inflator pressure remains stable within a safe range and preventing the infusion bag from rupturing or the medication from being infused too quickly due to excessive pressure.

[0060] Reference Figure 3 and Figure 4 , Figure 3 The circuit diagram of the liquid level sensor in an embodiment of the present invention is shown. Figure 4 A circuit diagram of a pressure sensor according to an embodiment of the present invention is shown. In some embodiments, the level sensor includes a JCS-08A sensor, the pressure sensor includes an MSP300 sensor, and the controller includes an STM32 chip. The VCC pin of the JCS-08A sensor is connected to one end of a first resistor, the GND pin of the JCS-08A sensor is grounded, the SDA pin of the JCS-08A sensor is connected to one end of a second resistor and the PB7 pin of the STM32 chip, the SCL pin of the JCS-08A sensor is connected to one end of a third resistor and the PB6 pin of the STM32 chip, and the INT pin of the JCS-08A sensor is connected to one end of a fourth resistor and the PA0 pin of the STM32 chip. The other ends of the first, second, and third resistors are connected to a 5V power supply, and the other end of the fourth resistor is connected to a 3.3V power supply.

[0061] The V+ pin of the MSP300 sensor is connected to one end of the fifth resistor, the V- pin is grounded, and the OUT pin is connected to one end of the sixth resistor. The other end of the fifth resistor is connected to a 12V power supply, and the other end of the sixth resistor is grounded.

[0062] It should be noted that the first resistor is Figure 3 The resistor R1 in the middle, the second resistor is Figure 3 The resistor R2 in the middle, the third resistor is Figure 3 The resistor R3 in the middle, the fourth resistor is Figure 3 The resistor R4 in the middle, the fifth resistor is Figure 4 The resistor R5 in the middle, the sixth resistor is Figure 4 The resistor R6 in the middle.

[0063] The liquid level sensor uses an ultrasonic sensor or a miniature radar sensor. It emits sound waves or electromagnetic waves to the bottom of the infusion bag and receives the echoes. By calculating the round-trip time of the waves, it accurately determines the distance to the liquid surface. Its advantages are that it is pollution-free, easy to install, and unaffected by the color of the liquid.

[0064] The pressure sensor is a diffused silicon pressure sensor, integrated into the control box and installed on the inside of the first pipeline. It is in direct contact with the gas in the pipeline and is used to detect the air pressure data in the airbag in real time. It can quickly capture the dynamic changes in air pressure and provide accurate basis for the controller to adjust the power of the air pump.

[0065] The pressure sensor employs a sealed enclosure, exhibiting excellent corrosion resistance and stability. It can withstand the instantaneous pressure surges during air pump inflation and adapt to the operating environment within the control box, maintaining drift-free operation over extended periods. The sensor connects to the controller via a dedicated interface, converting the detected analog air pressure signal into a digital signal and transmitting it to the controller in real time. The controller analyzes the air pressure data using a built-in algorithm to determine whether the current pressurization status meets clinical requirements.

[0066] Reference Figure 2 Furthermore, in some embodiments, the pressurized infusion system further includes: a communication module and a server. The communication module is connected to the controller and is used to receive liquid level data, air pressure data and control data, and to feed back the liquid level data, air pressure data and control data to the server. The server is also used to send the user's control signals to the communication module so that the communication module can transmit control signals to the controller for execution.

[0067] It should be noted that in some embodiments, the communication module is a core hardware module added to enable remote monitoring via the APP. The communication module includes any one of the following: a Wi-Fi or 4G / Cat.1 wireless communication chip module, which is responsible for uploading data from the device to the cloud server and receiving remote control commands from the cloud. It is the gateway for the device to access the Internet of Things.

[0068] The cloud server is a remote high-performance computer deployed on the Internet. It serves as a data relay and processing center between the device and the user's APP, and is responsible for device management, user authentication, data storage and forwarding, command routing, etc., to ensure the stability and real-time performance of remote monitoring and control.

[0069] Reference Figure 5 , Figure 5 A flowchart illustrating the control method in an embodiment of the present invention is shown. In some embodiments, the control method for the pressurized infusion system is applied to the pressurized infusion system of the above embodiments, and the control method may include, but is not limited to, steps 101 to 103:

[0070] Step 101: Obtain real-time data on the infusion bag's liquid level and the air pressure inside the airbag.

[0071] Step 102: Identify the infusion progress based on the liquid level data to obtain the infusion stage.

[0072] Step 103: Determine the target air pump power based on the infusion stage, and adjust the air pump power according to the air pressure data and the target air pump power.

[0073] It should be noted that after acquiring the infusion bag's liquid level data and the air pressure data inside the airbag in real time, the liquid level data is converted into infusion progress, which is divided into three infusion stages according to the liquid level height. Each infusion stage corresponds to adjusting the air pump power. The corresponding infusion stage is identified based on the current liquid level data, and the target air pump power to be adjusted is determined. Based on the current air pressure data and compared with the target air pressure range, the direction of adjustment for increasing, decreasing, or maintaining the air pump power is determined, and the current power of the air pump is adjusted to the target air pump power according to the adjustment direction.

[0074] Reference Figure 6 , Figure 6 A flowchart illustrating the control method in an embodiment of the present invention is shown. In some embodiments, the infusion stage includes: an initial stage, a middle stage, and a final stage. The progress of the infusion is identified based on the fluid level data, and the infusion stage specifically includes, but is not limited to, steps 201 to 203:

[0075] Step 201: Compare the liquid level data with the first liquid level data range. If the liquid level data is within the first liquid level data range, the initial stage is obtained.

[0076] Step 202: Compare the liquid level data with the second liquid level data range. If the liquid level data is within the second liquid level data range, the intermediate stage is obtained.

[0077] Step 203: Compare the liquid level data with the third liquid level data range. If the liquid level data is within the first liquid level data range, the final stage is obtained.

[0078] It should be noted that the liquid level is divided into three stages: initial stage (0-40%), middle stage (40%-70%), and final stage (70%-100%). Each stage has a preset pressure range: initial stage: 0.02-0.04MPa, middle stage: 0.04-0.07MPa, and final stage: 0.07-0.1MPa.

[0079] Reference Figure 7 , Figure 7 A flowchart illustrating the control method in an embodiment of the present invention is shown. In some embodiments, the target air pump power includes: a first-stage power, a second-stage power, and a third-stage power. The target air pump power is determined based on the air pressure data and the infusion stage. Adjusting the air pump power according to the air pressure data and the target air pump power specifically includes, but is not limited to, steps 301 to 303:

[0080] Step 301: If the infusion stage includes an initial stage, then adjust the power of the air pump to the first level power according to the air pressure data.

[0081] Step 302: If the infusion stage includes an intermediate stage, adjust the power of the air pump to the second level based on the air pressure data.

[0082] Step 303: If the infusion stage includes the final stage, adjust the power of the air pump to the third level based on the air pressure data.

[0083] It should be noted that the air pump power is adjusted in stages: based on the deviation between the current air pressure and the target air pressure, and in conjunction with the infusion progress stage, adjustments are made in stages: small deviation: 0.1-0.2W, medium deviation: 0.3-0.5W, large deviation: 0.8-1.0W, to avoid sudden changes in the infusion rate. Furthermore, the infusion progress rate is optimized in conjunction with the calculation of the liquid level change rate, infusion rate, and combined with the current infusion stage and air pressure data, to further optimize the power. If the rate is too slow at the end and the air pressure reaches the upper limit, the power is slightly increased. In addition, there is adaptive adjustment for abnormal operating conditions: the power is reduced before a low liquid level warning; when the air pressure changes suddenly, the maximum power is adjusted according to the progress; and the pump is immediately stopped when sensor data is abnormal.

[0084] In addition, this application also discloses a control device for a pressurized infusion system, please refer to... Figure 8 , Figure 8 This invention discloses a block diagram of a control device according to an embodiment of the present invention. In some embodiments, the pressurized infusion system can implement the above-described control method for the pressurized infusion system. The control device includes: a detection data acquisition module, an infusion stage identification module 802, and an air pump power adjustment module 803. The detection data acquisition module, the infusion stage identification module 802, and the air pump power adjustment module 803 are all communicatively connected.

[0085] The detection data acquisition module 801 acquires the liquid level data of the infusion bag and the air pressure data inside the air bladder in real time. The infusion stage identification module 802 identifies the infusion progress based on the liquid level data to determine the infusion stage. The air pump power adjustment module 803 determines the target air pump power based on the infusion stage and adjusts the air pump power accordingly.

[0086] The detection data acquisition module 801 acquires the liquid level data of the infusion bag and the air pressure data inside the airbag in real time, and converts the liquid level data into infusion progress. The liquid stage identification module 802 divides the infusion into three infusion stages according to the liquid level height. Each infusion stage corresponds to the adjustment of the air pump power. Based on the current liquid level data, the corresponding infusion stage is identified, and the target air pump power to be adjusted is determined. The air pump power adjustment module 803 compares the current air pressure data with the target air pressure range, determines the adjustment direction of increasing, decreasing, or maintaining the air pump power, and adjusts the current power of the air pump to the target air pump power according to the adjustment direction.
