Description

Technical Field

[0001] The present invention relates to the technical field of medical care equipment, and in particular to a multifunctional infusion chair and an intelligent monitoring system thereof. Background Art

[0002] Infusion chair is a chair used for patients to receive infusion, also known as drip chair, bottle chair, mainly used in medical units to give patients infusion. The traditional infusion chair is a chair for patients to sit and receive infusion, with a single function and poor comfort. With the development of society and productivity, infusion chairs have evolved from simple chairs to multifunctional, comfortable, safe, and environmentally friendly ones, and their ease of use can also better take care of patients.

[0003] However, the existing infusion chair does not have the ability to monitor infusion. During the infusion process, medical staff and patients need to pay close attention to the infusion situation to ensure that they can detect and take appropriate treatment measures in time when the medicine is exhausted. However, when patients are receiving infusions, especially at night, they may easily forget to check whether the medicine has been exhausted due to various reasons. When there are many patients, medical staff may not be able to detect the exhaustion of the medicine in time, and the patient may experience blood backflow or local tissue swelling. In order to solve this problem, a monitor is currently used for monitoring. When the medicine is exhausted, the monitor will beep to remind. However, the existing monitor only has detection and beeping effects and cannot intervene. When the patient falls asleep or the medical staff does not hear it, the patient's hand may still experience blood backflow or local tissue swelling.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the Invention

[0005] The purpose of the present invention is to adjust the infusion speed in real time so that the infusion state reaches an ideal state, and to control the alarm device and the reminder system of the nurse station to issue an alarm prompt.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a multifunctional infusion chair, comprising a seat, a backrest and armrests, the outer two side surfaces of the seat are fixed with guard plates, the two armrests are respectively fixed to the top surface of the guard plates, the backrest is fixed to one side surface of the seat, the top surface of the backrest is fixed with an alarm, an extension plate is movably connected between the two guard plates, the top surface of the armrest is provided with a storage groove, the top surface of the storage groove is movably connected with a sealing cover plate, an oximeter is placed on the inner wall of the storage groove, a disinfection component is fixed on the inner wall of the sealing cover plate, an infusion bracket is connected to the top surface of any armrest, an infusion monitoring component is fixed on the outer surface of the infusion bracket, and a speed regulating component is fixed on the outer surface of the infusion bracket;

[0007] The speed regulation component includes a fixed clamp and an expansion bag. The fixed clamp is fixed on the outer surface of the infusion bracket. An insertion notch is opened inside the fixed clamp. The expansion bag is fixed on the inner wall of the fixed clamp. A micro air pump is fixed on the outer surface of the infusion bracket.

[0009] Furthermore, the liquid outlet component includes an electromagnet and a magnetic block, a piston block is movably connected to the inner wall of the liquid storage tank, the electromagnet is fixed inside the piston block, the magnetic block is fixed inside the storage slot, and a power switch is fixed on the top surface of the liquid storage tank.

[0010] Furthermore, the infusion monitoring component includes a fixed bracket and a camera, the fixed bracket is used to be fixed on the outer surface of the infusion bracket, and the camera is fixed on the bottom surface of the fixed bracket.

[0011] Furthermore, a wireless charging plate is fixedly provided on the top surface of the armrest, and a mobile phone slot is opened on the top surface of the armrest.

[0012] The present invention also provides an intelligent monitoring system for a multifunctional infusion chair, comprising a data acquisition unit, an image analysis unit, a monitoring and analysis unit, and an infusion control unit;

[0013] The data acquisition unit includes an information entry module and a monitoring data acquisition module. The information entry module is used to obtain the patient's personal information and medical information and send them to the monitoring and analysis unit. The monitoring data acquisition module obtains the patient's blood oxygen data through the oximeter and sends it to the monitoring and analysis unit. The blood oxygen data includes pulse rate, blood oxygen saturation and perfusion index. At the same time, the camera obtains real-time images of the medicine bottles on the infusion stand and sends them to the image analysis unit.

[0014] The image analysis unit is used to obtain real-time images, perform contour extraction based on the real-time images, obtain the size and drug content of the medicine bottle and the infusion flow rate data, and send them to the monitoring and analysis unit;

[0015] The monitoring and analysis unit includes an infusion status analysis module and a drug approval module. The infusion status analysis module is used to obtain the patient's personal information and blood oxygen data, and then calculate the patient's infusion balance coefficient, obtain the real-time infusion flow rate to determine the current infusion status, and generate a reminder signal to send to the infusion control unit;

[0016] The drug approval module is used to obtain the size and drug content of the medicine bottle and the patient's medical information, which includes the patient's disease diagnosis results and medication plan. The medication plan specifically includes the type and quantity of infusion drugs and the order of medication. The module verifies each medicine bottle based on the size and drug content, and generates an early warning signal to send to the infusion control unit.

[0017] The infusion control unit is used to obtain and process reminder signals and early warning signals. When obtaining a reminder signal, it controls the speed regulation component to adjust the infusion speed in real time so that the infusion state reaches the ideal state. When obtaining an early warning signal, it controls the alarm device and the reminder system of the nurse station to issue an alarm prompt.

[0018] Furthermore, the specific process of generating the reminder signal is as follows:

[0019] S101. Obtain the patient's personal information, including the patient's age and gender, and create a patient account based on the patient's personal information and tag the account;

[0020] S102. Evaluate the patient's baseline blood oxygen value based on the patient's personal information to obtain the patient's standard blood oxygen value range, specifically the pulse rate range (P1, P2), blood oxygen saturation (S1, S2), and perfusion index (PI1, PI2);

[0021] S103. Obtain the patient's blood oxygen data, including pulse rate Pt, blood oxygen saturation SaO2, and perfusion index PI, and calculate the patient's infusion balance coefficient Ki according to the following formula: Among them, e1, e2, e3 and α are preset weight coefficients, vi is the real-time infusion flow rate, is the conventional infusion flow rate. The infusion balance coefficient is used to evaluate the patient's physiological state during the infusion process. The larger the infusion balance coefficient, the more the patient's physiological state during the infusion process tends to be abnormal. Conversely, the smaller the infusion balance coefficient, the more the patient's physiological state during the infusion process tends to be normal.

[0022] S104: Obtain a preset infusion balance judgment threshold value, and generate a reminder signal if the infusion balance coefficient is greater than or equal to the infusion balance judgment threshold value.

[0023] Furthermore, the specific process of generating early warning signals is as follows:

[0024] S201, acquiring real-time images from multiple angles, performing denoising on the real-time images to obtain standard images, performing contour extraction on the standard images to obtain a medicine bottle outline, drawing the medicine bottle outline on the standard images to obtain a medicine bottle drawing, and calculating actual medicine bottle dimensions based on the medicine bottle drawing from multiple angles, the actual medicine bottle dimensions including the height and diameter of the medicine bottle;

[0025] S202, grayscale processing is performed on the drawn image of the medicine bottle to obtain the liquid area and the empty area within the outline of the medicine bottle, and the drug content data is obtained by comprehensive calculation based on the area of the liquid area at multiple angles;

[0026] S203: Mark the drug content data at the initial state of infusion as initial content data Vb, periodically obtain the remaining content data Vt during the infusion process, and calculate the real-time infusion flow rate Vi according to the following formula: Where T is the infusion time;

[0027] S204. Obtain the category and quantity of the infusion drug, search the database for the standard medicine bottle size corresponding to the category of the infusion drug, and generate a medicine list according to the medication order in the medication plan. The medicine list includes the drug category and the corresponding standard medicine bottle size. The actual medicine bottle size is compared with the standard medicine bottle size one by one. When the comparison results are inconsistent, a warning signal is generated.

[0028] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0029] 1. This multifunctional infusion chair uses a blood oximeter to obtain the patient's blood oxygen data during the infusion process. After the infusion is completed, the blood oximeter is returned to the storage tank, and the liquid storage tank is rotated to reset the sealing cover. At the same time, the power switch is pressed to energize the electromagnet and make it magnetic. Since the magnetism of the electromagnet and the corresponding surface of the magnetic block are opposite, the electromagnet drives the piston block downward under the action of magnetic attraction, and then the disinfectant in the liquid storage tank is sprayed out from the liquid outlet nozzle to disinfect the blood oximeter and avoid cross infection.

[0030] 2. During the infusion process, if the infusion is found to be too fast or the infusion is completed, the multifunctional infusion chair controls the micro air pump to inflate the expansion bag. After the expansion bag is inflated, it squeezes the infusion tube to adjust the speed or close the infusion channel to ensure that the patient will not experience blood backflow or local tissue swelling during the infusion process.

[0031] 3. The intelligent monitoring system of the multifunctional infusion chair extracts contours based on real-time images to obtain the size and drug content of the medicine bottle and the infusion flow rate data. At the same time, it obtains the patient's personal information and the patient's blood oxygen data, and then calculates the patient's infusion balance coefficient, obtains the real-time infusion flow rate to determine the current infusion status, and generates a reminder signal. It obtains the type and quantity of infusion drugs and the order of medication, and verifies each one according to the size and drug content of the medicine bottle to generate an early warning signal, and then adjusts the infusion speed in real time to make the infusion status reach the ideal state, and controls the alarm device and the reminder system of the nurse station to issue an alarm prompt.

The intelligent monitoring system for a multifunctional infusion chair according to claim 6, characterized in that: The specific process of generating early warning signals is as follows: S201, acquiring real-time images from multiple angles, performing denoising on the real-time images to obtain standard images, performing contour extraction on the standard images to obtain a medicine bottle outline, drawing the medicine bottle outline on the standard images to obtain a medicine bottle drawing, and calculating actual medicine bottle dimensions based on the medicine bottle drawing from multiple angles, the actual medicine bottle dimensions including the height and diameter of the medicine bottle; S202, grayscale processing is performed on the drawn image of the medicine bottle to obtain the liquid area and the empty area within the outline of the medicine bottle, and the drug content data is obtained by comprehensive calculation based on the area of the liquid area at multiple angles; S203: Mark the drug content data at the initial state of infusion as initial content data Vb, periodically obtain the remaining content data Vt during the infusion process, and calculate the real-time infusion flow rate Vi according to the following formula: Where T is the infusion time; S204. Obtain the category and quantity of the infusion drug, search the database for the standard medicine bottle size corresponding to the category of the infusion drug, and generate a medicine list according to the medication order in the medication plan. The medicine list includes the drug category and the corresponding standard medicine bottle size. The actual medicine bottle size is compared with the standard medicine bottle size one by one. When the comparison results are inconsistent, a warning signal is generated.
