DETAILED DESCRIPTION

[0023] In order to make the technical solutions in the embodiments of the present application or the prior art clearer, the accompanying drawings needed in the embodiments or prior art description will be briefly introduced below. Obviously, the accompanying drawings in the description below only represent some embodiments of the present application, and for those skilled in the art, other drawings can be obtained without any creative effort based on these drawings.

[0024] As Figures 1-4As shown, the intelligent infusion stand 100 in an embodiment of the present application includes a support 10 and a controller 21 fixed on the support 10 and a plurality of infusion assemblies 22, each of which includes an infusion bag compartment 221, a first power source 222, a first clamp 223 and a liquid level sensor 224, wherein the infusion bag compartment 221 is used to place an infusion bag, each of which is provided with a catheter for delivering a medicinal liquid to a patient, the liquid level sensor 224 is used to monitor the liquid level in the infusion bag, and the first clamp 223 is arranged on the catheter, and the first power source 222 is connected and drives the first clamp 223 to clamp or release the catheter. The controller 21 is fixed on the support 10, which receives the liquid level data of the liquid level sensor 244, connects and controls the first power source 222 to drive the first clamp 223 to clamp or release the corresponding catheter, and the controller 21 is provided with a plurality of keys 211 corresponding to the number of infusion bag compartments 221, and the infusion order can be set through the keys 211.

[0025] In actual use, the infusion bags needed to be used this time are placed in different infusion bag compartments 221, the controller 21 controls the first power source 222 corresponding to the currently used infusion bag to drive the first clamp 223 to release the catheter, and the remaining first power sources 222 drive the corresponding first clamps 223 to clamp the catheter. When the liquid level sensor 224 corresponding to the infusion bag in use detects that the liquid level in the infusion bag is lower than a set threshold value (such as less than 10 ml of medicinal liquid remaining), the controller 21 controls the first power source 222 to drive the first clamp 223 to clamp the catheter, and controls the first power source 222 corresponding to the next infusion bag to drive the corresponding first clamp 223 to release the catheter. When the liquid level sensor 224 corresponding to the last used infusion bag detects that the liquid level is lower than the set threshold value, the controller 21 controls the first power source 222 to drive the first clamp 223 to clamp the catheter, and no other first power source 222 drives the first clamp 223 to release the catheter. And the controller 21 is provided with a sequence control key 211, and the controller 21 can control the first power source 222 to work in a preset order, or control the working order through the key 211, especially when the number of infusion bag compartments 221 and infusion bags is large, medical staff do not need to place the infusion bags in the infusion bag compartments 221 in the order of infusion, and the flexibility is higher.

[0026] The intelligent infusion stand 100 in the embodiment can automatically replace the infusion bag according to the liquid level, and the patient, medical staff or accompanying personnel only need to place the infusion bag in the infusion bag compartment 221, and can not participate in the subsequent infusion process, thereby improving the safety, portability and intelligent level of home infusion.

[0027] In an embodiment, the liquid level sensor 224 is a high-precision infrared pair tube, which is fixed on both sides of the infusion bag at the position corresponding to the threshold height. The first power source 222 is a stepper motor, and the first gripper 223 is an infusion tube roller gripper with an inner diameter slightly larger than the outer diameter of the infusion tube, and the output shaft of the stepper motor is connected to the infusion tube roller gripper through a shaft coupling.

[0028] Preferably, the support 10 is provided with a master control module 60, which is the control center of the entire intelligent infusion support 100, used to receive data from the controller 21 and send device information to the server through wired or wireless communication, so as to realize remote monitoring of the infusion sequence and the liquid level threshold of liquid replacement, and at the same time, when necessary, the controller 21 can be skipped, and the first power source 222 can be directly controlled remotely to interrupt the infusion or temporarily adjust the infusion sequence, etc.

[0029] In an embodiment, the intelligent infusion support 100 further comprises a drip speed control module 30 fixed on the support 10, used to adjust the drip speed. It comprises a light sensor 31, a second power source 32 and a second gripper 33. The light sensor 31 is fixed on the outer wall of the drip chamber near the upper catheter outlet, used to detect the drip speed. The second gripper 33 is arranged on the catheter below the drip chamber. The master control module 60 controls the second power source 32 (such as a stepper motor) to drive the second gripper 33 to clamp or release the catheter by receiving the drip speed data of the light sensor 31. For example, when the light sensor 31 detects that the drip speed is too fast, the second power source 32 drives the second gripper 33 to clamp the catheter appropriately to slow down the drip speed; when the light sensor 31 detects that the drip speed is too slow, the second power source 32 drives the second gripper 33 to release the catheter appropriately to speed up the drip speed.

[0030] Specifically, when the liquid drops, the light sensor 31 blocks the infrared light emitted by the light sensor 31, and the light sensor 31 outputs an electrical signal, which is converted into a digital signal after signal conditioning and analog-digital conversion, and transmitted to the master control module 60. The master control module 60 processes and analyzes the digital signal according to a preset algorithm to calculate the drip speed and stability. To ensure data accuracy, the system continuously collects the time difference of multiple adjacent liquid drops and takes the average value to calculate the drip speed. After setting the target drip speed, the master control module 60 compares the real-time monitoring data with the target drip speed, and generates a control instruction to send to the second power source 32 when there is a deviation.

[0031] Preferably, the drop speed control module 30 further comprises a strain gauge 34 attached to the outer wall of the drip chamber. When the amount of liquid medicine in the drip chamber changes, the drip chamber will produce a slight deformation. The strain gauge 34 detects the deformation of the drip chamber and outputs an electrical signal, which is converted into a digital signal by a signal conditioning circuit and an analog-to-digital converter, and transmitted to the main control module 60. The main control module 60 obtains the liquid medicine amount data in the drip chamber through the strain gauge 34, which is used as an auxiliary reference for drop speed control.

[0032] Further, the drop speed control module 30 further comprises a protective film 35 attached to the outer wall of the drip chamber, which covers the entire strain gauge 34, so that the strain gauge 34 remains completely attached to the outer wall of the drip chamber, improving detection accuracy and avoiding gaps between the strain gauge 34 and the drip chamber.

[0033] Further, the intelligent infusion stand 100 further comprises a backflow detection module 50 for detecting whether backflow occurs during infusion, which comprises a mounting buckle 51, and an optical sensor 52 and a signal transmitter 53 fixed on the mounting buckle 51. The mounting buckle 51 is fixed to the infusion catheter near the needle, the optical sensor 52 is used to detect whether there is backflow of blood in the catheter, and the signal transmitter 53 transmits the detection data of the optical sensor 52 to the main control module 60.

[0034] The intelligent infusion stand 100 further comprises an index monitoring module, which comprises a monitoring bracelet 41 and an infrared sensor (not shown in the figure) in communication connection with the main control module 60. The monitoring bracelet 41 is provided with a blood oxygen sensor and is worn on the patient's hand to monitor the patient's blood oxygen and other data. The infrared sensor is non-contact and is installed on the stand 10 and faces the patient to obtain the patient's body temperature data.

[0035] It is easily conceivable that other sensors for monitoring pulse, heart rate and other data can also be provided on the monitoring bracelet 41 to expand the monitoring range and improve the practicability.

[0036] In an embodiment, the monitoring bracelet 41 comprises a buckle-fixed plastic shell, and the sensors are installed in the shell. A medical-grade silica gel band is connected to the shell, and a magic tape is provided on the surface of the silica gel band to fix the monitoring bracelet 41 on the patient's hand. A wireless signal transmitter is provided in the shell, and the sensor data is transmitted to the main control module 60 through the wireless signal transmitter after analog-to-digital conversion. Medical staff can monitor the patient's heart rate, pulse and other data in real time through the terminal APP.

[0037] Preferably, the monitoring bracelet 41 adopts a magnetic charging mode, and a magnetic charging compartment 43 for supplementing power to the monitoring bracelet 41 is provided on the stand 10. When the monitoring bracelet 41 is out of power, it can be placed on the magnetic charging compartment 43.

[0038] In an embodiment, the support 10 is made of 6063-T5 medical aluminum alloy material, and the surface is treated by anodic oxidation to have corrosion resistance and wear resistance. The height of the support 10 is adjustable, and a stepping motor is used to drive an adjustment controller 21 and a transfusion assembly 22 to adjust the position of the transfusion assembly 22 in the vertical direction, so as to facilitate the operation of patients and medical staff of different body types. The base is a triangular reinforced structure, and is provided with three medical rubber wheels to facilitate movement and fixation.

[0039] The main control module 60 receives data of the adjustment controller 21, the transfusion assembly 22, the drop speed control module 30, the index monitoring module, and the back blood detection module 50, integrates and preliminarily processes the data, and uploads the data to a cloud server. The client receives data of the cloud server to view the transfusion state in real time. When detecting data abnormities such as excessively high or low body temperature, excessively high or low heart rate, back blood in the catheter, or abnormal drop speed, the main control module 60 issues an alarm (sound or light signal) and sends an abnormal data signal to the cloud server, and medical staff remotely sends a control instruction to the intelligent transfusion support 100 when necessary, so as to remotely control and manage.

[0040] In summary, the intelligent transfusion support 100 in the embodiment integrates automatic liquid replacement, index detection, back blood detection, and other functions, greatly improves the convenience of patient transfusion, and enables patients to meet the transfusion demand without going out. Secondly, the functions of automatic liquid replacement, drop speed control, and back blood monitoring ensure the continuity and safety of transfusion, and reduce the nursing burden and anxiety of patients and their families. At the same time, potential abnormal conditions (abnormal body temperature, heart rate, and back blood) in the transfusion process can be found and warned in time, and the transfusion, liquid replacement, and drop speed can be remotely controlled when necessary, effectively reducing the incidence of medical accidents and improving the medical quality and service level. The entire intelligent transfusion support 100 has a compact structure, is convenient to install and use, and supports flexible function expansion and upgrading. The modular design facilitates maintenance and troubleshooting, reduces the maintenance cost and time of the equipment, and the equipment can operate stably for a long time.
