Description

Technical Field

[0001] The invention relates to the field of ICU fluid management, in particular to a real-time processor for bedside data of ICU fluid management. Background Art

[0002] ICU fluid management is an important treatment task in the intensive care unit (ICU), involving the precise monitoring and management of the patient's fluid input and output. Due to the unstable systemic hemodynamics of critically ill patients, the fluid infusion rate and total amount need to be very precise, so the demand for fluid management is very high. The purpose of ICU fluid management is to ensure the patient's fluid balance and avoid adverse reactions caused by too much or too little fluid, which means that the input and output of fluids need to be precisely controlled to achieve the best treatment effect;

[0003] Therefore, medical staff need to monitor the patient's intake and output in real time, and strictly control and limit the input and output of fluids. According to the patient's specific situation, the intake and output need to be adjusted in real time to achieve balanced fluid management.

[0004] Since ICU patients need to use a large number of different types of infusion pumps, including conventional infusion pumps, micro-infusion pumps, syringe pumps and insulin pumps, to meet their complex infusion needs, the traditional method of managing fluid intake and output relies on bedside nurses to calculate the patient's intake and output in real time and feed it back to the attending physician to make clinical decisions and ensure that the patient's fluid management achieves the expected goals;

[0005] However, due to the wide variety of infusion pumps, this method has lags and subjectivity. Especially for critically ill patients with unstable systemic hemodynamics, the speed and total amount of fluid infusion require extremely high accuracy. Any slight error may lead to worsening of the patient's condition. For this reason, a real-time processor for ICU fluid management bedside data is provided. Summary of the invention

[0006] In order to solve the above problems, the present invention proposes a real-time processor for bedside data of ICU fluid management, comprising a processor housing and a detection mechanism;

[0007] The detection mechanism is arranged inside the processor housing;

[0008] The processor housing is convex as a whole, and a U-shaped groove is provided on the top surface of the processor housing;

[0009] A top pressure cover is provided on the top of the U-shaped groove;

[0010] The U-shaped groove is used to prevent intravenous infusion access.

[0013] Preferably, a rectangular frame plate is fixedly connected to the interior of the processor housing, and a mounting substrate is fixedly connected to the bottom surface of the rectangular frame plate;

[0014] A control circuit board is fixedly connected to the top surface of the mounting substrate, and the ultrasonic flow sensor is connected to the control circuit board through a wire.

[0015] Preferably, a vertical plate is fixedly mounted on the bottom surface of the top pressure cover, a first card block is fixedly mounted on a side of the vertical plate close to the processor housing, and a second card block is fixedly mounted on the left side of the processor housing close to the top.

[0016] Preferably, a plurality of return springs are symmetrically fixedly mounted on the inner side wall of the U-shaped groove, and one end of the return spring away from the inner side wall of the U-shaped groove is fixedly connected to the limit plate.

[0017] Preferably, a bottom sealing plate is fixedly mounted on the bottom surface of the processor housing by means of hexagon socket bolts.

[0018] Preferably, a retractable shielding cloth is fixedly mounted on the inner side wall of the U-shaped groove, and one end of the retractable shielding cloth away from the inner side wall of the U-shaped groove is fixed to one side of the limiting plate.

[0039] Unless otherwise defined, technical or scientific terms used in the present invention shall have the common meanings understood by one having ordinary skills in the field to which the present invention belongs.

[0040] like Figure 1-Figure 6 , the present invention provides a real-time processor for bedside data of ICU fluid management, including, a processor housing 1 and a detection mechanism;

[0041] Further, such as Figure 3 , Figure 4 and Figure 5 As shown, a rectangular frame plate 7 is fixedly connected to the inside of the processor housing 1, and a mounting substrate 8 is fixedly connected to the bottom surface of the rectangular frame plate 7;

[0042] The rectangular frame plate 7 is provided to facilitate personnel to install and fix the installation base plate 8 using screws, thereby facilitating the installation and removal of the installation base plate 8 .

[0043] like Figure 3 , Figure 4 and Figure 5 As shown, a control circuit board 9 is fixedly connected to the top surface of the mounting substrate 8, and the ultrasonic flow sensor 6 is connected to the control circuit board 9 via a wire.

[0044] The control circuit board 9 is the center of the whole device. It integrates a data processor and a data analyzer, can receive signals from the ultrasonic flow sensor 6, and perform complex processing and analysis. The control circuit board 9 mainly includes the following components: microcontroller (MCU), sensor interface, analog-to-digital converter (ADC), digital signal processor (DSP), memory, communication interface, etc. Through the coordinated work of these components, the control circuit board 9 can efficiently process and analyze the signals monitored and fed back by the ultrasonic flow sensor 6, and output the processed results;

[0045] The model of the control circuit board 9 may be ADALM1000.

[0046] Furthermore, a bottom sealing plate 16 is fixedly mounted on the bottom surface of the processor housing 1 by means of hexagon socket bolts.

[0047] The bottom sealing plate 16 is provided to facilitate sealing the bottom of the processor housing 1, so that the processor housing 1 can form a whole. At the same time, when the personnel unscrew the hexagon socket bolts, the components installed inside the processor housing 1 can be inspected and maintained.

[0048] Further, such as Figure 1 , Figure 3 and Figure 4 As shown, a display 10 is provided on one side of the processor housing 1, and the control circuit board 9 is connected to the display 10 via a signal line;

[0049] A communication interface connected to the control circuit board 9 is installed on one side of the processor housing 1. The display 10 is connected to the control circuit board 9 by a signal line, which facilitates the feedback of the signal processed by the control circuit board 9 to the display 10. The display 10 can display the data in real time, which is convenient for medical staff to observe and record and provide timely feedback, thereby improving convenience. The display 10 is a device that can be purchased directly in reality. The present invention only uses it without improving its structure, and no further elaboration is made here. The display 10 can select a display 10 with an alarm, which facilitates the issuance of an alarm when subsequent data exceeds the set value.

[0050] like Figure 4 , Figure 5 and Figure 6 A plurality of heat dissipation holes 18 are provided on the right side of the processor housing 1 .

[0051] The multiple heat dissipation holes 18 are provided to facilitate the circulation of external air and the air inside the processor housing 1 .

[0052] The detection mechanism is arranged inside the processor housing 1;

[0053] The processor housing 1 is convex as a whole, and a U-shaped groove 2 is provided on the top surface of the processor housing;

[0054] like Figure 1 , Figure 2 and Figure 3 , the U-shaped groove 2 is used to prevent the intravenous infusion passage 4.

[0055] Furthermore, limiting plates 3 are provided on both sides of the interior of the U-shaped groove 2, and the limiting plates 3 are used to limit the intravenous infusion pathway 4; by providing the U-shaped groove 2, it is convenient to place the intravenous infusion pathway 4, and by providing two limiting plates 3, it is convenient to limit the intravenous infusion pathway 4 inside the U-shaped groove 2, so that it will not move significantly left and right.

[0056] like Figure 2 , Figure 3 and Figure 4 As shown, circular grooves 5 are formed on opposite sides of the limiting plate 3 , and ultrasonic flow sensors 6 are fixed inside the circular grooves 5 .

[0057] The circular groove 5 is provided to facilitate the installation and fixation of the ultrasonic flow sensor 6. This design can ensure that the sensor accurately monitors the liquid flowing inside the intravenous infusion passage 4. The ultrasonic flow sensor 6 contains a transmitter and a receiver. The transmitter sends ultrasonic signals, which propagate in the liquid and are then received by the receiver. Since the flow of the fluid causes the propagation time of the ultrasonic signal to change, the flow rate of the fluid can be accurately calculated by measuring the time difference between the transmitted and received signals. At the same time, the total amount of liquid can be calculated based on the flow rate and time by the integration method. This design effectively solves the problem of lack of real-time monitoring and precise control in the traditional intravenous infusion management method, and provides a reliable guarantee for the safe infusion of patients.

[0058] There are many types of ultrasonic flow sensor 6, which can be selected according to actual debugging needs. The present invention provides an ultrasonic flow sensor 6 model 1ME21TR-1.

[0059] Further, such as Figure 2 , Figure 3 and Figure 4 As shown, a plurality of return springs 15 are symmetrically fixedly installed on the inner side wall of the U-shaped groove 2 , and one end of the return spring 15 away from the inner side wall of the U-shaped groove 2 is fixedly connected to the limit plate 3 .

[0060] By setting up multiple return springs 15, it is convenient to use intravenous infusion pathways 4 of different sizes, thereby improving practicality. The elastic force of the return spring 15 can be selected according to actual debugging needs. The selected elastic force of the return spring 15 cannot be too large, otherwise it will cause squeezing effect on the intravenous infusion pathway 4 and liquid flow.

[0061] Furthermore, a retractable shielding cloth 17 is fixedly mounted on the inner side wall of the U-shaped groove 2 , and one end of the retractable shielding cloth 17 away from the inner side wall of the U-shaped groove 2 is fixed to one side of the limiting plate 3 .

[0062] The retractable shielding cloth 17 is provided to conveniently shield the partially exposed structures of the reset spring 15 and the ultrasonic flow sensor 6, thereby improving the appearance and preventing foreign objects from falling into the structure, thereby improving the practicality.

[0063] like Figure 4 , Figure 5 and Figure 6 As shown, a top pressure cover 11 is provided on the top of the U-shaped groove 2;

[0064] Furthermore, a vertical plate 12 is fixedly installed on the bottom surface of the top pressure cover 11, a card block 13 is fixedly installed on one side of the vertical plate 12 close to the processor housing 1, and a card block 2 14 is fixedly installed on the left side of the processor housing 1 close to the top.

[0065] By setting the top pressure cover 11, it is convenient to protect the intravenous infusion passage 4 inside the U-shaped groove 2, and try to prevent the intravenous infusion passage 4 from escaping from the inside of the U-shaped groove 2. When the top pressure cover 11 is closed, the block 13 contacts the block 2 14, so it is convenient to limit and fix the top pressure cover 11.

[0066] Further, such as Figure 2 , Figure 4 and Figure 6 As shown, an arc-shaped tilting 19 is fixedly installed on the top surface of the top pressure cover 11. The top pressure cover 11 and the arc-shaped tilting 19 are both made of plastic materials, which makes it easy for people to push the arc-shaped tilting 19 upward to open the top pressure cover 11, thereby improving convenience.

[0067] Further, such as Figure 2 , Figure 4 and Figure 6 As shown, a sponge pad 20 is fixedly installed on the bottom surface of the top pressure cover 11 , and the sponge pad 20 is arranged so that the top pressure cover 11 will not affect the intravenous infusion passage 4 .

[0068] The implementation principle of the embodiment of the ICU liquid management bedside data real-time processor of the present invention is as follows: the operator first selects a suitable position beside the ICU bed to place the display 10 so that the medical staff can observe and record data, and then places the processor housing 1 on the bed or the bedside table stool. This design takes into account the convenience of use, so that the operator can easily approach and operate. Then, the operator puts the intravenous infusion passage 4 into the limiting plate 3. At this time, the reset spring 15 will generate a certain thrust to ensure that the intravenous infusion passage 4 is effectively limited. This design is not only suitable for intravenous infusion passages 4 of different sizes, but also improves the convenience of use. Then, two symmetrically installed ultrasonic flow sensors 6 will be close to the surface of the intravenous infusion passage 4;

[0069] When the liquid inside the intravenous infusion passage 4 begins to flow, the transmitter of the ultrasonic flow sensor 6 will emit ultrasonic signals, which propagate in the liquid and are received by the receiver. Since the flow of the liquid will cause the propagation time of the ultrasonic signal to change, these changed signals will be monitored and fed back to the control circuit board 9. The control circuit board 9 integrates a data processor and a data analyzer, which will process and analyze the monitoring data, and convert the results into digital signals and output them to the display 10. In this way, medical staff can observe the flow rate and total amount of the liquid through the display 10. The data is presented in digital form, which is convenient for medical staff to observe, record and report in time. The device has a simple structure and is easy to operate. Through the design of the limit plate 3, it can adapt to intravenous infusion passages 4 of different sizes, which improves the flexibility and convenience of use. At the same time, the ultrasonic flow sensor 6 can effectively monitor the flow rate and total amount of different liquids in the intravenous infusion passage 4, without the need for personnel to observe the liquid flow rate and flow data on the infusion pump one by one and record and process them one by one, which can effectively help medical staff better manage the liquid state of critically ill patients, thereby improving the treatment effect and the safety of patients.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical method of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical method to deviate from the spirit and scope of the technical method of the present invention.
