Description

[0002] Intravenous infusion is one of the most commonly used medical treatments in clinical medicine. However, the current management of intravenous infusion still uses traditional manual management methods. If medical staff fail to monitor in time and fail to stop the infusion in time at the end of the infusion, it will cause blood backflow or needle bruising, which will have adverse effects on the patient's health. At present, the infusion devices used in hospitals need to rely on medical staff or patients to monitor the infusion status and adjust the infusion speed. When the infusion is about to end, medical staff must be manually called to remove the infusion needle from the patient's body or block the infusion tube to stop the infusion.

The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] In the present invention, “first” and “second” do not represent specific numbers and orders, but are only used to distinguish names.

[0029] like Figure 1 and Figure 2As shown, an infusion monitoring system in one embodiment of the present invention includes an infusion monitoring system, including a monitoring device 1 and a monitoring platform; the monitoring device 1 is provided with a detection chamber adapted for an infusion drip bucket, and the monitoring device 1 includes an electrically connected photoelectric sensing component 2, a microprocessor, a display module, a wireless communication module, and an infusion tube blocking component 3. The photoelectric sensing component 2 is disposed in the detection chamber and is used to detect the dripping speed of the dripping bucket and send a dripping signal to the microprocessor; the wireless communication module is used to communicate with the monitoring platform; the display module is disposed on the clamping component and is used to display the dripping speed; the infusion tube blocking component 3 is disposed below the drip bucket and is used to stop the flow of liquid medicine in the infusion tube; when the microprocessor calculates that the dripping speed is zero, it sends an early warning signal to the monitoring platform via the wireless communication module, and the microprocessor sends a drive signal to the infusion tube blocking component 3, which stops the flow of liquid medicine in the infusion tube. Specifically, the drip bucket is also called a Mofei dropper.

[0030] The above-mentioned infusion monitoring system monitors the dripping speed of the liquid droplets in the drip bucket in real time by setting a photoelectric sensing component 2, and the microprocessor processes the liquid droplet signal to determine whether the infusion is finished. When it is determined that the infusion is finished, it sends a driving signal to the infusion tube blocking component 3 to stop the flow of the liquid medicine in the infusion tube below the drip bucket, thereby avoiding the situation of blood back or needle bruise caused by the negligence of medical staff or the patient himself to pull out or block the infusion tube in time, so that medical staff and patients are not distracted by the infusion status, thereby reducing the workload of medical staff, improving the quality of medical services, and allowing patients to rest assured.

[0031] like Figure 3 As shown, in one embodiment, the infusion tube blocking assembly 3 includes a driving member 31 and a pressing rod 32. The pressing rod 32 has a connecting end 321 and a pressing end 322. The connecting end 321 is connected to the driving member 31, and the pressing end 322 is provided with a rotatable roller. The pressing rod 32 is arranged at an acute angle with the infusion tube, and the driving member 31 drives the pressing rod 32 to move along the axial direction of the pressing rod 32. Specifically, the pressing rod 32 is arranged at an acute angle with the direction of delivery of the liquid medicine in the infusion tube. As a result, when the pressing rod 32 presses against the infusion tube, the infusion space below the pressing rod 32 forms a sealed space within the infusion tube. The liquid medicine in the sealed space has a liquid suction force, which may cause the blood in the patient's veins to flow back into the infusion tube due to the suction force. The driving member 31 drives the pressing rod 32, causing the roller at the pressing end 322 to roll the infusion tube, squeezing the liquid medicine in the infusion tube and delivering it to the patient's veins, thereby preventing the blood from flowing back into the infusion tube due to the suction force.

[0032] In one embodiment, the infusion tube blocking assembly 3 is provided with a positioning surface 33 adapted to accommodate the push rod 32. The positioning surface 33 is fixed relative to the infusion tube. Specifically, the positioning surface 33 is disposed within the detection chamber. Thus, when the push rod 32 presses against the infusion tube, the infusion tube is pressed against the positioning surface 33, thereby ensuring the blocking effect of the infusion tube blocking assembly 3 and further preventing venous backflow in the patient.

[0033] In one embodiment, the driving member 31 is a micro electric telescopic rod, and the pressing rod 32 is arranged at the rod end of the micro electric telescopic rod. In this way, the micro electric telescopic rod has a compact structure and uses the telescopic rod to directly press, ensuring a safe and reliable blocking effect of the infusion.

[0034] In one embodiment, the driving member 31 is a driving motor assembly, which includes a driving motor and a rotating and retractable screw member. In this way, the driving motor drives the screw member to rotate and retract, thereby facilitating the control of the extension stroke of the screw member and ensuring a safe and reliable blocking effect of the infusion.

[0035] In one embodiment, the monitoring device 1 includes an RFID sensor electrically connected to a microprocessor; an RFID tag is provided on the infusion bottle, the RFID sensor identifies the RFID tag and sends the infusion bottle information to the microprocessor; the microprocessor receives the drop signal and calculates the remaining infusion time of the current infusion bottle, and displays the remaining infusion time on the display module. RFID (Radio Frequency Identification) is a technology that uses spatial coupling of wireless radio frequency signals to achieve contactless automatic transmission and identification of tag information. In this way, by using the RFID tag to identify the capacity of the infusion bottle and the patient's name and other related information, the RFID sensor is used to identify the RFID tag, thereby obtaining the infusion bottle capacity information and sending it to the microprocessor, so that patients can intuitively estimate their infusion time, thereby improving the user's medical care experience.

[0036] In one embodiment, the RFID sensor is provided on the infusion stand, so as to improve the recognition accuracy of the RFID sensor and enhance the quality of medical care services.

[0037] like Figure 3As shown, in one embodiment, the photoelectric sensing assembly 2 includes a dripping rate detection group 21 and a liquid level detection group 22; the dripping rate detection group 21 includes a first infrared emitting tube and a first infrared receiving tube, and the first infrared emitting tube and the first infrared receiving tube are arranged on opposite sides of the air storage part of the drip bucket. The first infrared emitting tube transmits a first infrared signal to the first infrared receiving tube. When no liquid drops, there is no obstacle between the receiving tube and the transmitting tube, and they are directly reflected. The first infrared receiving tube will be turned on, and the first infrared receiving tube will send a first photoelectric signal to the microprocessor; when liquid drops, there is an obstacle between the receiving tube and the transmitting tube, and the first infrared receiving tube will be turned off, thereby collecting the infusion dripping rate; the liquid level detection group 22 includes a second infrared emitting tube for emitting a second infrared signal and an adapted second infrared receiving tube; the second infrared emitting tube and the second infrared receiving tube are respectively arranged on opposite sides of the infusion tube above the drip bucket. When there is no liquid drop in the infusion tube, there is no obstacle between the receiving tube and the transmitting tube, and they are directly reflected. The second infrared receiving tube will be turned on, and the second infrared receiving tube will send a second photoelectric signal to the microprocessor. In this way, the droplet status in the infusion tube is detected by combining the droplet detection group 21 and the liquid level detection group 22, thereby improving the sensing accuracy of the photoelectric sensing component 2, thereby reducing the workload of medical staff and improving the quality of medical services.

[0038] In a specific embodiment, when the infusion is completed, no liquid drops fall from the air storage part of the drip bucket, and the dripping speed is zero. The liquid level detection group 22 detects that there are no liquid drops in the infusion tube above the drip bucket and sends a second photoelectric signal to the microprocessor.

[0039] In one embodiment, the monitoring platform is provided with a warning component, and the warning component is provided with an audible and visual alarm circuit, and the audible and visual alarm circuit is used to alert medical staff; the system also includes a portable device, and the monitoring platform is provided with a communication module, and the monitoring platform is connected to the portable device through the communication module. When the monitoring device 1 detects that the infusion is completed, the generated detection signal of the end of the infusion is simultaneously transmitted to the monitoring platform, and the monitoring platform connects to the audible and visual alarm circuit to perform an alarm action and simultaneously sends a communication signal to the portable device, and the portable device generates a corresponding alarm signal to remind the infusion person or medical staff; the portable device is one or more of a smart terminal or a nameplate. In this way, the medical staff is reminded by the audible and visual alarm circuit to avoid no one to handle the current infusion after the end; in addition, by carrying the portable device with you, it is convenient for medical staff to promptly handle the patient after the infusion is completed, thereby reducing the workload of medical staff and improving the quality of medical services.

[0040] In one embodiment, the system also includes a dressing change drip stand, which includes a fixed bracket, a rotating assembly and a needle insertion and extraction assembly. The rotating assembly includes a fixed base, a rotating frame and a rotating motor; the fixed base is fixedly installed on the fixed bracket, and the rotating motor drives the rotating frame to rotate relative to the fixed base. The rotating frame is provided with multiple liquid bottle clamping ports, which are used to clamp infusion bottles; the needle insertion and extraction assembly includes a driving motor, a gear rack group, and a clamping member. The clamping member is used to clamp the insertion needle of the infusion tube, and the driving motor drives the insertion needle on the clamping member to move up and down through the gear rack group. In this way, medical staff clamp multiple infusion bottles for the same patient onto the bottle clamping port on the rotating rack and secure the insertion needle to the clamp. The RFID sensor recognizes the RFID tags on the infusion bottles and obtains the number of infusion bottles to be infused. The microprocessor controls the drive motor to move the insertion needle upward and insert it into the first infusion bottle. When the first infusion bottle is finished, the microprocessor controls the drive motor to move the insertion needle downward and out of the first infusion bottle. The rotary motor drives the rotating rack to rotate so that the second infusion bottle stops above the insertion needle. The microprocessor controls the drive motor to move the insertion needle upward and insert it into the second infusion bottle, thus completing the dressing change of the infusion bottles. This allows for timely and automatic dressing change of infusions, reducing the workload of medical staff and improving the quality of medical care.

[0041] In one embodiment, the system also includes a detection patch, which includes a substrate, an antenna coil and a chip, and the antenna coil and the chip are arranged on the substrate; the chip is electrically connected to the antenna coil; the chip includes a capacitive sensor and a detection circuit electrically connected to the capacitive sensor, and the capacitive sensor is used to convert the displacement signal of the patient's intravenous infusion site monitored into an electrical signal, and transmit the electrical signal to the detection circuit; the detection circuit is used to convert the electrical signal into a digital signal, and transmit the digital signal to the antenna coil; the antenna coil is used to send the received digital signal to the monitoring device 1. On the one hand, the monitoring device 1 is close to the detection patch, which is convenient for saving energy consumption of the detection patch and improving detection accuracy; on the other hand, the patient may experience leakage of injection liquid during the infusion process, and the delivered liquid medicine cannot enter the blood vessels, but enters the subcutaneous part, causing edema at the infusion site. By attaching the detection patch to the infusion port of the patient's intravenous infusion, the displacement signal of the patient's intravenous infusion site is monitored by the capacitive sensor, and a monitoring signal is sent to the microprocessor, and then sent to the monitoring platform through the wireless communication module, so that medical staff can monitor the infusion status in real time, thereby avoiding waste of liquid medicine and timely handling of edema, thereby improving the quality of medical services.

[0042] In one embodiment, the chip also includes an RFID circuit for storing patient information. The RFID sensor recognizes the RFID circuit, reads the patient information, and sends it to the microprocessor, which verifies the patient information against the infusion bottle information. This avoids manual verification errors that could strain the medical relationship, reduces the workload of medical staff, and improves the quality of medical care.

[0043] In one embodiment, the chip further includes a heartbeat sensing circuit and a temperature sensing circuit electrically connected to the antenna coil. The heartbeat sensing circuit is used to obtain the patient's real-time heartbeat information, and the temperature sensing circuit is used to obtain the patient's real-time body temperature information. In this manner, a patient may develop an infection during an infusion, leading to phlebitis. Phlebitis can cause symptoms such as local tissue swelling, burning, pain, and redness, as well as systemic symptoms such as fever and chills. By monitoring the patient's heartbeat and body temperature in real time, the heartbeat sensing circuit and temperature sensing circuit, respectively, can prevent major medical incidents and strained doctor-nurse relationships caused by phlebitis, provide timely attention to the patient's physical condition, address emergencies, and improve the quality of medical care.

[0044] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above embodiments merely illustrate several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
