theoretical analysis, when the equipment starts, the infrared LED starts to work, emits infrared light and shoots at the infusion tube, the photoelectric receiver is responsible for receiving the

changes, and then an electric signal is generated, the signal converter amplifies these weak electric signals, then through filtering and other operations, effectively filters out noise and interference signals, finally converts the processed analog electric signal into a digital signal, and transmits it to the data processor, the data processor calculates the transmittance according to

pre-stores a corresponding relationship model between the pressure in the infusion tube and the liquid flow rate established according to a large amount of experimental data and theoretical analysis, which considers factors such as the diameter, material of the infusion tube and the viscosity of the liquid, the micro pressure sensor works with internal pressure sensitive elements, when there is liquid flowing in the infusion tube, it will exert pressure on the pressure sensor, at this time, the resistance value in the sensor will change linearly with the pressure, by accurately measuring the

pressure range during normal infusion, the data processor will determine that the infusion tube is blocked, at this time, the display screen will flash and alarm, and the alarm record will be stored in the data storage, in addition, when the pressure continuously stays at a low level, the data processor automatically sends a signal to the controller, the controller will drive the infusion transmission motor to automatically adjust the speed to compensate for the error until the pressure value returns to normal, The multi-level alarm system mainly realizes the following steps when executed: The infusion tube clamp is placed in the infusion tube limiting ring, and then passes between the infusion tube limiting ring transverse plate and the two infusion tube limiting plates, and the bottom end of the infusion tube is pressed and clamped between the two rotating plates and the placement plate through the two positioning rollers, and the infusion tube is clamped in the mounting hole near the two ends of the infusion tube pump shell. The driving of the infusion conveying motor drives the rotating shaft to rotate, so that the infusion roller rotates around the circular sliding, and the infusion roller extrudes the infusion tube in sequence, forming a local vacuum area in the infusion tube. The liquid in the infusion tube is sucked into the area, and the sucked liquid is pushed forward by the subsequent infusion tube as the infusion roller continues to rotate. Such a cycle realizes the transportation of the liquid. In the process of liquid transmission, the infrared LED starts to work, emits infrared light to the infusion tube, and the photoelectric receiver receives the infrared light through the infusion tube. The signal converter converts the electrical signal into a digital signal. The data processor calculates the bubble volume according to the digital signal output by the signal converter. Once the calculated bubble volume is greater than.ml, the data processor sends a signal to the controller. After the controller receives the signal, on the one hand, the audible alarm is driven to alarm, and an emergency notification is pushed to the main system. On the other hand, the infusion conveying motor is immediately controlled to stop working to ensure the safety of infusion, and the alarm record is stored in the data storage. At the same time, the liquid flow rate of the infusion tube is calculated according to the motor encoder, the pressure in the infusion tube is converted into an electrical signal by the micro pressure sensor, and the electrical signal is output to the signal converter. The signal converter converts the received electrical signal into a digital signal and transmits it to the data processor. The data processor continuously monitors the pressure. Once the pressure continuously rises and exceeds the normal pressure range during infusion, the data processor will determine that the infusion tube is blocked. At this time, the display screen will flash and alarm, and the alarm record will be stored in the data storage. In addition, when the pressure continuously remains at a low level, the data processor automatically sends a signal to the controller. The controller drives the infusion conveying motor to automatically adjust the rotating speed to compensate for the error until the pressure value returns to normal. When a staff member comes to handle the alarm, the empty button needs to be pressed to determine that a staff member is handling the alarm. Otherwise, the alarm will continue. When a staff member discovers an accident during drug injection, the alarm button can also be pressed to send an alarm to the system, so that the controller stops working and records it in the data storage. Further, the support spring (23) is sleeved with a support sleeve (25), the length of the support sleeve (25) is less than the shortest length of the support spring (23), the support spring (23) corresponds to the support sleeve (25) one by one, and the support sleeve (25) is in a cylindrical structure.

Each auxiliary heating ring (28) corresponds to a set of heating resistance wires (30). A set of heating resistance wires (30) has multiple wires. The multiple heating resistance wires (30) in each set are arranged circumferentially along the auxiliary heating rings (28), and the multiple heating resistance wires (30) in a set are connected in series. Preferably, the heating resistance wire (30) is made of constantan wire. When in use, insert the infusion tube (5) between two thermally conductive silicone gaskets (29) with opposite opening directions. After installation, start the heating resistance wire (30). The heat generated will be quickly absorbed by the thermally conductive silicone gaskets (29). Due to the good thermal conductivity of the thermally conductive silicone gaskets, the heat can be quickly and evenly conducted to the side of the infusion tube (5) to heat the internal drugs. The two thermally conductive silicone gaskets (29) have opposite opening directions, which can ensure that the entire side of the infusion tube (5) can be effectively heated, avoiding the situation where some injected drugs are not heated or are heated unevenly, and ensuring that the drugs are heated to a suitable temperature during infusion.

In use, the thermally conductive silicone pad (29) can be adjusted through the deformation adaptation holes (31) to conform to the thermally conductive silicone pad (29). When subjected to external force, it undergoes a small elastic deformation. When infusion tubes (5) of different sizes are placed between two thermally conductive silicone gaskets (29), the thermally conductive silicone gaskets (29) undergo adaptive deformation through the deformation adaptation hole (31) and fit tightly against the outer wall of the infusion tube (5), thereby achieving the adaptation of infusion tubes (5) of different sizes. In this process, the good thermal conductivity of the thermally conductive silicone gaskets (29) is not affected, and it can continuously and efficiently conduct heat to the side of the infusion tube (5) to achieve uniform heating of the drug. Example 3

The auxiliary heating ring (28) has a cylindrical structure and a cross-section of three-quarters of a circular structure, which can better fit the outer surface of the infusion tube, increase the contact area with the infusion tube, improve the heat transfer efficiency, and at the same time facilitate the installation and disassembly of the infusion tube, making the operation convenient. The auxiliary heating ring (28) is provided in two parts. The two auxiliary heating rings (28) are arranged along their axial direction and the opening directions of the two auxiliary heating rings (28) are opposite. This design can heat different parts of the infusion tube (5), avoid the problem of uneven heating that may be caused by a single heating area, and ensure that the sides of the infusion tube (5) can be heated, so that the injected drug is heated more evenly. The thermally conductive silicone gasket (29) has a cylindrical structure and a three-quarter circular cross-section. The thermally conductive silicone gasket (29) corresponds one-to-one with the auxiliary heating ring (28). The outer side of the thermally conductive silicone gasket (29) is fixedly connected to the inner side of its corresponding auxiliary heating ring (28). The thermally conductive silicone gasket (29) has good thermal conductivity and can quickly and effectively conduct the heat generated by the heating resistance wire to the side of the infusion tube (5), thereby improving the heating efficiency. At the same time, the silicone material has a certain degree of flexibility and can fit tightly to the infusion tube (5), further enhancing the heat transfer effect and providing a certain degree of protection for the infusion tube, preventing damage due to direct contact with the heating element. The heating resistance wire (30) is made of constantan wire, which has the characteristics of low temperature coefficient of resistance and good stability. During the heating process, the heating power can be controlled more accurately to ensure that the heating temperature does not exceed the required range, avoid adverse effects on the injected drug due to excessive temperature, and ensure the safety and effectiveness of the drug.

The improved medical infusion pump of the present invention also includes a multi-level alarm system, which comprises a signal converter, a data processor, a data storage device, a controller, and a main system. The signal converter is located inside the display housing (1), and the data processor is located inside the display housing (1). The audible and visual alarm (6), alarm button (7), empty button (8), and infusion conveyor motor (20) are connected to the controller via data cables. The photoelectric receiver (22) is connected to a signal converter via a data transmission line, and the motor encoder inside the infusion delivery motor (20) is connected to the signal converter. The signal converter and the data processor interact with each other, and the data processor is connected to the data memory. The data storage device pre-stores a model relating light transmittance to bubble volume, established based on extensive experimental data and theoretical analysis. When the device is started, the infrared LED... (24) Start working, emit infrared light and shoot it toward the infusion tube. The photodetector (22) is responsible for receiving the infrared light passing through the infusion tube (5). During this process, the energy of the photons is transferred to the electrons in the photoelectric element, causing the electron state to change and thus generating an electrical signal. The signal converter amplifies these weak electrical signals and then effectively filters out noise and interference signals through filtering and other operations. Finally, the processed analog electrical signal is converted into a digital signal and transmitted to the data processor. The data processor calculates the transmittance based on the digital signal output by the signal converter. Then, it compares and analyzes the calculated transmittance with the relationship model stored in the data memory in advance, and then uses a specific algorithm to calculate the bubble volume. Once the calculated bubble volume is greater than 0.5 ml, the data processor will send a signal to the controller. After receiving the signal, the controller will drive the sound and light alarm (6) to sound an alarm and push an emergency notification to the main system. On the other hand, it will immediately control the infusion delivery motor (20) to stop working to ensure infusion safety and store the alarm record in the data memory. The motor encoder generates pulse signals as the infusion delivery motor (20) rotates. The signal converter amplifies, filters, and adjusts these signals into appropriate digital signals. The data processor calculates the motor speed by counting the number of pulses per unit time based on the preset encoder parameters. Then, combined with the pre-determined volume of liquid pumped per revolution of the infusion delivery motor (20), the liquid flow rate in the infusion tube (5) is calculated using a formula. The data storage device pre-stores a model of the relationship between pressure and flow rate in the infusion tube, established based on a large amount of experimental data and theoretical analysis. This model considers various factors such as the diameter, material, and viscosity of the infusion tube (5). The miniature pressure sensor (21) operates using an internal pressure-sensitive element. When there is liquid flowing in the infusion tube (5), pressure is applied to the miniature pressure sensor (21). At this time, the resistance value inside the miniature pressure sensor (21) changes linearly with the pressure. By accurately measuring this change in physical characteristics, the pressure sensor can convert the pressure in the infusion tube (5) into electrical signals. The signal is received and output to a signal converter, which converts the received electrical signal into a digital signal and transmits it to a data processor. The data processor continuously monitors the pressure. If the pressure continues to rise and exceeds the normal pressure range for infusion, the data processor will determine that the infusion tube (5) is blocked. At this time, the display screen (3) will flash an alarm and record the alarm in the data memory. In addition, when the pressure remains at a low level, the data processor automatically sends a signal to the controller, which will drive the infusion delivery motor (20) to automatically adjust its speed to compensate for the error until the pressure value returns to normal. When the multi-level alarm system is executed, it mainly performs the following steps: The infusion tube (5) is placed inside the infusion tube limiting ring (18) and passes between the horizontal plate of the infusion tube limiting ring (18) and the two infusion tube limiting plates (19). The bottom end of the infusion tube (5) is pressed between the two positioning rollers (12) and inserted between the two rotating plates (11) and the placement plate (15). The two ends of the infusion tube (5) near the infusion pump housing (2) are then placed in the mounting holes (9). The infusion transfer motor (20) drives the rotating shaft (16) to rotate, causing the infusion roller (17) to slide in a circle. The infusion roller (17) squeezes the infusion tube (5) in turn, forming a local vacuum area inside the infusion tube (5). The liquid inside the infusion tube (5) is then sucked into this area. As the infusion roller (17) continues to rotate, the sucked liquid is pushed forward by the subsequent infusion tube (5). This cycle repeats to achieve liquid delivery. During the liquid transfer process, the infrared LED... The lamp (24) starts working, emitting infrared light and shining it onto the infusion tube (5). The photodetector (22) is responsible for receiving the infrared light passing through the infusion tube (5). The signal converter converts the electrical signal into a digital signal. The data processor calculates the bubble volume based on the digital signal output by the signal converter. Once the calculated bubble volume is greater than 0.5 ml, the data processor sends a signal to the controller. After receiving the signal, the controller drives the audible and visual alarm (6) to sound an alarm and pushes an emergency notification to the main system. On the other hand, it immediately controls the infusion delivery motor to stop working to ensure infusion safety and stores the alarm record in the data memory. At the same time, it calculates the liquid flow rate in the infusion tube (5) using a formula based on the motor encoder. The pressure in the infusion tube (5) is converted into an electrical signal by the miniature pressure sensor (21) and output to the signal converter. The signal converter receives the signal. The received electrical signal is converted into a digital signal and transmitted to the data processor. The data processor will continuously monitor the pressure. Once the pressure continues to rise and exceeds the normal pressure range for infusion, the data processor will determine that the infusion tube (5) is blocked. At this time, the display screen (3) will flash and alarm, and the alarm will be recorded and stored in the data memory. In addition, when the pressure is continuously at a low level, the data processor will automatically send a signal to the controller. The controller will drive the infusion delivery motor (20) to automatically adjust the speed to compensate for the error until the pressure value returns to normal. When a staff member comes to handle the alarm, the clear button (8) needs to be pressed to confirm that a staff member has handled the alarm. Otherwise, the alarm will continue. When a staff member finds an accident during the drug injection process, the alarm button (7) can also be pressed to send an alarm to the system, thereby driving the controller to stop working and recording and storing the data in the data memory.

[0018] The difference between this embodiment and embodiment 1 is that: a support sleeve (25) is fitted on the support spring (23), the length of the support sleeve (25) is less than the shortest length of the support spring (23), the support spring (23) and the support sleeve (25) correspond one-to-one, the support sleeve (25) has a cylindrical structure, when in use, the support sleeve (25) can effectively support the rotating plate (11), ensuring that the rotating plate (11) maintains a reasonable position and angle when the spring extends and retracts, so that the two rotating plates (11) always maintain a suitable opening distance, and medical staff can easily and quickly insert the infusion tube (5), which improves the convenience and efficiency of operation; Example 3

[0019] The difference between this embodiment and embodiment 1 is that: the infusion roller (17) is fitted with an infusion roller protective sleeve (26) on its side. The infusion roller protective sleeve (26) has a cylindrical structure. The infusion roller (17) is made of rubber. When in use, the soft material of the infusion roller protective sleeve (26) effectively avoids physical damage to the infusion tube (5) caused by excessive friction, thus extending the service life of the infusion tube (5). The design of the motor encoder installed in the motor shaft of the infusion delivery motor (20) can monitor the rotation of the infusion delivery motor (20) in real time, convert the rotation information into an electrical signal output, and, combined with the signal converter and data processor, accurately calculate the rotation speed of the infusion delivery motor (20), thereby achieving precise control of the infusion flow rate and meeting the precise requirements of various clinical infusion treatment plans. The design of placing the infusion roller (17) in the placement groove of the rotating shaft (16) and rotating it to the rotating shaft (16) allows the infusion roller (17) to squeeze the infusion tube (5) in sequence under the drive of the infusion delivery motor (20). This can both promote the flow of liquid and reduce damage to the infusion tube (5), thus ensuring the quality and safety of the infusion. One end of the support spring (23) is fixedly connected to the side of the placement plate (15), and the other end of the support spring (23) is fixedly connected to the middle of the side of the rotating plate (11). There are two sets of support springs (23), and each set of support springs (23) corresponds to the rotating plate (11). There are multiple support springs (23) in each set. The multiple support springs (23) in each set are arranged at equal intervals along the length of the rotating plate (11). The elastic force provided by the support springs (23) allows the rotating plate (11) to flexibly adapt to infusion tubes (5) of different sizes. No matter what the diameter of the infusion tube (5) is, the rotating plate (11) can fix it in a stable position. At the same time, medical staff can more easily lock or remove the infusion tube (5) and reduce the probability of damage to mechanical components. The photoelectric receiver (22) is fixed between the two rotating slots on the side of the placement plate (15). The design of working in conjunction with the infrared LED lamp (24) can monitor the changes in light transmittance in the infusion tube (5) in real time. By detecting the changes in light transmittance caused by air bubbles, the air bubbles in the infusion tube (5) can be accurately identified, potential infusion risks can be detected in time, and the infusion safety of patients can be guaranteed. The design of the miniature pressure sensor (21) fixed between the two rotating slots on the side of the placement plate (15) utilizes the internal pressure-sensitive element to work. When there is liquid flowing in the infusion tube (5), it can convert the pressure change into an electrical signal output. By monitoring the pressure in the infusion tube in real time, it can promptly detect blockage of the infusion tube and abnormal liquid flow rate, providing an important basis for the safety monitoring of the infusion process. The other side of the display housing (1) is designed with an audible and visual alarm (6), an alarm button (7), and a clear button (8). The audible and visual alarm uses a combination of sound and light to quickly send a strong signal when there are excessive bubbles, blockages, or abnormal pressure during infusion. It can also attract the attention of medical staff in noisy or complex lighting environments, expand the warning range, and avoid oversights. The alarm button gives medical staff the power to manually trigger the alarm, enabling them to respond flexibly when the system does not respond in time or encounters special accidents, thus enhancing their sense of control over infusion safety. The clear button plays a role when medical staff deal with alarms. Pressing it can confirm the processing status, avoid repeated processing, restore the system to normal, and improve data recording, providing a basis for medical management and process optimization.

[0020] The system enables the infusion assembly to drive the flow of liquid while simultaneously monitoring changes in air bubbles, pressure, and flow rate within the infusion tubing in real time. An alarm is triggered by a display component for any abnormalities, and the controller then adjusts the relevant equipment according to the specific circumstances, thereby ensuring a safe and stable infusion process.
