Description

Technical Field

[0001] This invention relates to the field of anesthesia nursing technology, specifically to an intelligent real-time detection and blocking system for abnormal drug infusion in anesthesia nursing. Background Technology

[0002] Anesthesia care is a crucial part of the perioperative period, involving three stages: preoperative assessment, intraoperative monitoring, and postoperative recovery. It ensures patient safety, reduces pain, and prevents complications. Drug infusion in anesthesia care plays multiple physiological and therapeutic roles, far beyond a simple route of administration. One of its core functions is to maintain hemodynamic stability. Anesthetic drugs often cause vasodilation and myocardial depression, leading to a drop in blood pressure. Appropriate intravenous fluid administration can effectively prevent and treat this drug-induced hypotension, ensuring perfusion of vital organs. Crystalloid solutions such as normal saline or lactated Ringer's solution play a key role in this process, rapidly replenishing intravascular volume and maintaining effective circulating blood volume.

[0003] For example, a drug infusion device, blockage detection method, detection system, and storage medium disclosed in CN116096443A include: a housing, a motor, an infusion line, and a first pump, a squeezing pump assembly, and a second pump connected to the motor and sequentially arranged on the infusion line path; a detection component arranged on the infusion line path; and a data processor connected to the detection component. The detection component detects the status parameters of the infusion line and sends the detected status parameters to the data processor. The data processor determines the blockage of the infusion line based on the first status parameter detected by the detection component in the first infusion stage and the second status parameter detected by the detection component in the second infusion stage. The existing technologies mentioned above have the following technical problems: Although existing drug infusion systems can monitor and block infusion data during drug infusion, they are not convenient to adjust the temperature of the infused drug according to the external temperature. When the temperature of the infused drug is low, the low-temperature liquid entering the blood circulation will take away heat, resulting in a decrease in body temperature. Long-term or frequent use of cold liquid infusion may increase the risk of vasospasm and affect blood circulation and tissue oxygen supply.

[0004] Therefore, we proposed a real-time detection and blocking system for intelligent drug infusion abnormalities in anesthesia care to address the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a real-time detection and blocking system for intelligent drug infusion abnormalities in anesthesia care, in order to solve the problems mentioned in the background art. Although existing drug infusion systems on the market can monitor and block infusion data during drug infusion, they are not convenient to adjust the temperature of the infused drug according to the external temperature. When the temperature of the infused drug is low, the cold liquid entering the blood circulation will take away heat, resulting in a decrease in body temperature. Long-term or frequent use of cold liquid infusion may increase the risk of vasospasm and affect blood circulation and tissue oxygenation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a real-time detection and blocking system for abnormal intelligent drug infusion in anesthesia nursing, comprising a container block for placing an infusion bottle and an infusion tubing inserted into the infusion bottle. A detection unit is installed on the infusion tubing, controlled by a controller. The input terminal of the controller and the output terminal of the central processing unit are interconnected. An electrically controlled blocking valve is installed at one end of the infusion tubing near the infusion bottle. The central processing unit, controller, detection unit, data processing module, execution unit, electrically controlled blocking valve, and alarm constitute the real-time detection and blocking system for abnormal infusion tubing. The alarm is fixed to the side of the container block, and a heating module is installed inside the container block. The heating module is used to heat the drug to be infused inside the infusion bottle, and the heating module is interconnected with a heat preservation module via a drainage tube. The heat preservation module is fitted onto the infusion tubing to keep the drug infused in the infusion tubing warm, reducing heat loss of the drug during infusion.

[0007] Preferably, the detection unit includes a pressure sensor and a microflow rate sensor, and three pressure sensors are provided on the infusion line, namely pressure sensor A, pressure sensor B and pressure sensor C.

[0008] By adopting the above technical solution, when the infusion drug in the infusion line becomes blocked, the pressure of the drug on the infusion line is different in the corresponding pressure sensor location area, thereby determining the drug blockage.

[0009] Preferably, the detection unit transmits the detection data information to the data processing module, and after the data processing module processes the detection data, it controls the electrically controlled shut-off valve to close through the execution unit. When the data processing module receives an abnormal signal, it controls the detection unit to repeatedly and continuously detect the infusion pipeline, and the number of continuous detections is at least three.

[0010] By adopting the above technical solution, the blockage of the infusion line may be caused by external factors such as human pressing or misoperation. Through continuous detection, the results caused by human operation can be eliminated, thereby improving the reliability of the final detection results.

[0011] Preferably, the heating module includes a movable block, and a detection plug is fixed to the side of the movable block. The detection plug is connected to the inner wall of the receiving block through an auxiliary spring. A clamping unit is provided on the inner side of the movable block. A heater is fixed in the clamping unit. The clamping unit is connected to the movable block through a built-in spring. A diverter nozzle is connected to the side of the clamping unit. An electromagnet is fixed to the side of the movable block facing the clamping unit. A guide magnet fixed to the clamping unit is provided on the side of the electromagnet.

[0012] By adopting the above technical solution, the auxiliary spring can be set so that the clamping unit can rebound as the weight of the infusion bottle is reduced.

[0013] Preferably, the clamping unit is symmetrically arranged about the transverse central axis of the movable block, the detection plug on the side of the movable block can slide on the receiving block, and a laser range sensor is arranged below the detection plug, which is electrically connected to the alarm.

[0014] By adopting the above technical solution, the distance to the detection block can be monitored through the setting of the laser range sensor, thereby determining whether the medicine in the infusion bottle has been used up.

[0015] Preferably, the inside of the clamping unit is a hollow structure, and the side of the clamping unit facing the infusion bottle is made of elastic metal, and the surface contour of the elastic metal is arc-shaped.

[0016] By adopting the above technical solution, when the clamping unit is squeezed against the infusion bottle, the airflow inside the clamping unit can be squeezed outward.

[0017] Preferably, multiple diverting nozzles are evenly distributed on the side of the clamping unit, and the diverting nozzles and the interior of the clamping unit are interconnected.

[0018] By adopting the above technical solution, when the clamping unit is compressed, the internal airflow can be sprayed out in other directions of the infusion bottle through the side diversion nozzle, thereby achieving all-round heating of the drug inside the infusion bottle and improving the uniformity of drug heating.

[0019] Preferably, the clamping unit is connected to the insulation module via a drainage hose. The insulation module includes a diversion block connected to the drainage hose. The diversion block is connected to the insulation sleeve via a delivery hose, and the insulation sleeve is fitted onto the infusion line.

[0020] By adopting the above technical solution, the insulation jacket can be used to reheat the transported liquid medicine, reducing heat loss during the transport process.

[0021] Preferably, the inside of the diversion block is a hollow structure, and the diversion block is interconnected with the internal cavity of the clamping unit through the drainage hose.

[0022] By adopting the above technical solution, when the clamping unit is compressed, the airflow inside can enter the interior of the diverter block through the drainage hose.

[0023] Compared with the prior art, the beneficial effects of the present invention are: the intelligent drug infusion abnormality real-time detection and blocking system for anesthesia care, by setting a detection unit, can be used to monitor the flow rate and abnormal blockage during drug infusion, and can block the infusion system in time when an abnormality is detected. In addition, it can be used to heat the infused drugs when the temperature is low, reducing the stimulation of low temperature drugs to patients. 1. Equipped with a pressure sensor, when the infusion line becomes blocked, the pressure sensor detects different pressures on the infusion line caused by the drug, thus determining the blockage. At the same time, the blockage may be caused by external factors such as manual pressing or misoperation. Through continuous detection, the results caused by human operation can be eliminated, improving the reliability of the final detection results. 2. It is equipped with a clamping unit, which can fix the infusion bottle through the arc-shaped clamping unit. At the same time, as the drug inside the infusion bottle decreases, the moving block and the detection plug reset under the action of the auxiliary spring. The distance between the moving block and the detection plug is measured by the laser range sensor, thereby determining the drug infusion volume. 3. A heater is provided, which uses the elastic metal on the surface of the clamping unit to absorb heat and transfer it to the medicine inside the infusion bottle, thereby heating the medicine inside the infusion bottle and reducing the stimulation of the human body caused by low-temperature medicine. 4. An electromagnet is provided. By intermittently switching the electromagnet on and off, a magnetic force is generated on the guide magnet. The repulsive magnetic force causes the elastic metal on the clamping unit to be squeezed by the infusion bottle. At this time, the airflow inside the clamping unit can be sprayed out to other parts of the infusion bottle through the diversion nozzle, thereby improving the uniformity of heating the medicine inside the infusion bottle. 5. An insulation sleeve is provided. The airflow in the clamping unit can enter the interior of the diversion block through the drainage hose. The airflow in the diversion block enters the insulation sleeve through the delivery hose. The heating of the insulation sleeve can reheat the drug in the infusion line, thereby avoiding the difference between the drug temperature during infusion and the initial heating temperature.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1: Please refer to Figures 1-9While existing drug infusion systems can monitor and block infusion data during drug infusion, they are not convenient for adjusting the temperature of the infused drug according to the external temperature. When the infused drug temperature is low, the cold fluid entering the bloodstream will carry away heat, leading to a drop in body temperature. Long-term or frequent use of cold fluid infusions may increase the risk of vasospasm, affecting blood circulation and tissue oxygenation. To solve this technical problem, this embodiment discloses the following technical content: a real-time detection and blocking system for abnormal intelligent drug infusion in anesthesia care, including a container block 1 for placing the infusion bottle and an infusion tubing 2 inserted into the infusion bottle, with a detection unit installed on the infusion tubing 2. The detection unit is controlled by the controller. The input terminal of the controller and the output terminal of the central processing unit are interconnected. An electrically controlled shut-off valve 5 is installed on the end of the infusion line 2 near the infusion bottle. The central processing unit, controller, detection unit, data processing module, execution unit, electrically controlled shut-off valve 5, and alarm 6 constitute the real-time detection and shut-off system for abnormalities in the infusion line 2. The alarm 6 is fixed to the side of the receiving block 1, and a heating module 7 is installed inside the receiving block 1. The heating module 7 is used to heat the drug to be infused inside the infusion bottle, and the heating module 7 is interconnected with the heat preservation module 9 through the drainage hose 8. The heat preservation module 9 is sleeved on the infusion line 2 and is used to keep the drug infused in the infusion line 2 warm. To reduce heat loss of the drug during infusion, the detection unit includes a pressure sensor 3 and a microflow sensor 4. Three pressure sensors 3 (A, B, and C) are installed on the infusion line 2. The detection unit transmits the detected data to the data processing module, which processes the data and then controls the electrically controlled shut-off valve 5 to close via the execution unit. When the data processing module receives an abnormal signal, it controls the detection unit to perform repeated continuous detection on the infusion line 2 at least three times. The heating module 7 includes a movable block 701, and a detection insert is fixed to the side of the movable block 701. 702, the detection plug 702 is connected to the inner wall of the receiving block 1 by the auxiliary spring 703, and the inner side of the movable block 701 is provided with a clamping unit 704. The clamping unit 704 is fixed with a heater 705. The clamping unit 704 is symmetrically arranged about the transverse central axis of the movable block 701. The detection plug 702 on the side of the movable block 701 can slide on the receiving block 1. A laser range sensor 10 is provided below the detection plug 702. The laser range sensor 10 is electrically connected to the alarm 6. The inside of the clamping unit 704 is set as a hollow structure, and the side of the clamping unit 704 facing the infusion bottle is made of elastic metal material, and the surface contour of the elastic metal is arc-shaped.

[0028] During drug infusion, the clamping unit 704 is pushed outwards from the receiving block 1, and then the infusion bottle is placed inside the clamping unit 704. The clamping unit 704 clamps the infusion bottle using the reset force provided by the built-in spring 706. The controller activates the heater 705, which heats the elastic metal surface of the clamping unit 704. Through the contact between the elastic metal and the infusion bottle, the drug inside the infusion bottle is heated, preventing the drug temperature from being too low. The heated drug enters the body through the infusion tubing 2. During the infusion process, the pressure sensor 3 monitors the pressure in the infusion tubing 2, and the microflow sensor 4 monitors the drug flow rate in the infusion tubing 2. When the corresponding path of the infusion tubing 2... When a blockage occurs in the tubing, the pressure of the medication on the tubing decreases. At this time, the pressure sensor 3 detects the pressure change and transmits the signal to the execution unit through the data processing module. The execution unit then controls the electrically controlled shut-off valve 5 to close, thereby automatically blocking the infusion tubing 2 in case of an abnormal signal. Simultaneously, when abnormal data occurs during real-time monitoring, the execution unit controls the alarm 6 to activate, providing an audible and visual alarm to those nearby, facilitating subsequent manual intervention. As the amount of medication inside the infusion bottle decreases, the weight of the infusion bottle lightens. At this time, the movable block 701 and the detection plug 702 gradually reset under the action of the auxiliary spring 703. The distance of the detection plug 702 is measured by the laser range sensor 10, thereby determining the amount of medication infused.

[0029] Example 2: The technical content disclosed in this example is a further improvement based on Example 1. This example discloses a heat preservation module 9, used for secondary heating of the drug in the infusion line 2. The specific disclosure is as follows: Figure 1 and Figure 3 As shown, the clamping unit 704 is interconnected with the insulation module 9 via the drainage hose 8. The insulation module 9 includes a diversion block 901 interconnected with the drainage hose 8. The diversion block 901 is interconnected with the insulation sleeve 903 via the delivery hose 902, and the insulation sleeve 903 is fitted onto the infusion line 2. The interior of the diversion block 901 is hollow, and the diversion block 901 communicates with the internal cavity of the clamping unit 704 via the drainage hose 8. The clamping unit 704... The built-in spring 706 and the movable block 701 are interconnected. The side of the clamping unit 704 is connected to the diversion nozzle 707. An electromagnet 708 is fixed on the side of the movable block 701 facing the clamping unit 704. A guide magnet 709 fixed on the clamping unit 704 is provided on the side of the electromagnet 708. Multiple diversion nozzles 707 are evenly distributed on the side of the clamping unit 704, and the diversion nozzles 707 and the interior of the clamping unit 704 are interconnected.

[0030] After the clamping unit 704 clamps the infusion bottle, the electromagnet 708 is intermittently activated. When the electromagnet 708 is energized, it generates a repulsive magnetic force on the guide magnet 709. Under the action of the magnetic force, the clamping unit 704 can move. At this time, the infusion bottle squeezes the elastic metal on the clamping unit 704. After the elastic metal is compressed, the volume of the cavity inside the clamping unit 704 decreases. At this time, part of the airflow inside the clamping unit 704 blows hot air through the diversion nozzle 707 towards other areas of the infusion bottle that are not covered by the clamping unit 704, thereby improving the uniform heating of all parts of the infusion bottle. At the same time, another part of the airflow can enter the interior of the diversion block 901 through the drainage tube 8. The airflow in the diversion block 901 enters the insulation sleeve 903 through the delivery tube 902. The heating of the insulation sleeve 903 can reheat the drug in the infusion line 2, thereby avoiding the difference between the drug temperature during infusion and the initial heating temperature.

[0031] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
