Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical treatment, in particular to an intelligent drainage bag for monitoring drainage volume based on a scraper-type flowmeter. Background Art
[0002] Current drainage bags are widely used in wards. The drainage bags commonly used in clinical practice are composed of a plastic bag with a scale and a drainage tube and a drain valve fixed at the upper and lower ends of the plastic bag. Although the plastic bag is marked with a scale, due to the strong plasticity of the plastic bag, the flow scale is often inaccurate, which cannot meet the clinical need for detailed measurement of drainage fluid volume. For example, urine volume needs to be recorded after heart surgery, and drainage volume per unit time needs to be recorded regularly after craniotomy. This requires a drainage device that can measure the flow per unit time and accurately measure the drainage volume.
[0003] To accurately measure drainage volume, this utility model is designed based on a volumetric flowmeter. This design incorporates a cam-type scraper flowmeter in addition to the existing drainage bag. This is primarily used for precise drainage volume measurement. A 51 single-chip microcomputer monitoring system is also incorporated to electronically monitor flow. Different detection thresholds are set based on applicable conditions. When a patient's drainage volume exceeds the set threshold, an alarm is promptly sent to the host computer, emitting an audible and visual alarm within the ward. Utility Model Content
[0004] The utility model aims to solve the above technical problems and provides an intelligent monitoring drainage bag based on the drainage volume of a scraper flow meter.
[0005] In order to solve the above technical problems, the technical solution provided by the present invention is:
[0006] The utility model adopts an improved drainage bag, which is equipped with 9 flow meters ( Figure 2 ) to achieve accurate measurement of flow, the flow meter workflow is as follows Figure 1 As shown, in combination with FIG (3), the number of revolutions of the flow meter can be controlled by the infrared sensor, thereby measuring the flow rate. The number of infrared revolutions is transmitted to the 51 single-chip microcomputer control system (13) through the Bluetooth module. The 51 single-chip microcomputer control system (13) monitors the flow monitoring start time and the monitoring amount, thereby achieving precise control of the instantaneous flow rate. At the same time, the threshold value can be set by the 51 single-chip microcomputer. When the threshold value is exceeded, an audible and visual alarm is turned on to prompt that the flow monitoring is abnormal. This improves the traditional method of relying on nursing staff for regular monitoring. The 51 single-chip microcomputer control system (13) and the host computer (14) system are used for data transmission through the wifi module, and the data content is displayed in real time at the nurse station, thereby reducing the workload of medical staff.
[0007] As an improvement, a scraper flow meter was added to the original drainage bag to achieve precise control of the drainage volume.
[0008] As an improvement, a 51 single-chip microcomputer control system was introduced, which was connected to the host computer via WiFi to enable the host computer to monitor the monitoring indicators in real time.
[0009] As an improvement, the 51 single-chip microcomputer control system is used to display the instantaneous flow and total flow, and automatically issues an audible and visual alarm in the ward in case of exceeding the set threshold. At the same time, the situation can also be transmitted to the host computer, so that nurses can grasp the patient's actual information in a timely manner.
[0010] As an improvement, the single-chip microcomputer control system realizes the automatic uploading of monitoring indicators, reducing the nursing workload of nurses and patients.
[0011] As an improvement, the recording time can be set through the host computer to achieve improvement.
[0012] As an improved 51 single chip microcomputer control system, it can be reused.
[0013] After adopting the above structure, the present invention has the following advantages:
[0014] The present invention proposes a device for accurately measuring drainage volume, and the device is suitable for drainage of various diseases. It is combined with an intelligent control system and realizes ward monitoring reminders through a 51 single-chip microcomputer, while transmitting data to the nurse station. While reducing the workload of medical staff, it can also provide doctors with accurate drainage volume monitoring, which is more conducive to the diagnosis of the disease.
[0015] At the same time, the invention of this device can change the traditional reliance on regular monitoring by personnel, and can effectively improve the nursing effect, especially reduce the workload of single-person nursing staff for cardiovascular and cerebrovascular surgery during the epidemic.

[0022] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.
[0023] The present invention will be described in further detail below with reference to the accompanying drawings.
[0024] This design uses the principle of volumetric flowmeter and realizes quantitative and accurate measurement of drainage volume by adding a scraper flowmeter to the original drainage bag. At the same time, the 51 single-chip microcomputer is used to connect the scraper flowmeter separately to ensure the recycling of the 51 single-chip microcomputer system. At the same time, the 51 single-chip microcomputer system can also record the number of revolutions of the scraper flowmeter to achieve accurate measurement and improve the accuracy of drainage volume. The 51 single-chip microcomputer control system and the host computer are connected through wifi. Different thresholds can be set according to the conditions of different patients. At the same time, the patient's drainage volume can be dynamically monitored by setting the threshold. When the set threshold is exceeded, an alarm signal is issued and the patient's flow situation is dynamically monitored. By setting the upload cycle, the patient's drainage volume is automatically collected, avoiding traditional manual monitoring and improving the problem that the drainage bag scale cannot achieve accurate quantitative measurement due to deformation of the bag body.
[0025] During the drainage process, the specific monitoring process is as follows: Figure 1 As shown, the accumulated fluid moves downward under the action of gravity. The scraper flowmeter set according to the volume principle can accurately measure the flow rate and then falls directly into the drainage bag. This improvement mainly adds a flowmeter in the design of the traditional drainage bag.
[0026] Figure 2This is a detailed schematic diagram of the flow meter. The entire annular cavity is divided into four grids with each grid being 90 degrees. It is composed of four slides (6) and moves around the cam (5) to form four cavities. When the accumulated liquid fills the volume cavity, it moves downward. Each rotation of 360 degrees is a circle. The number of circles and the speed are recorded by the 51 single-chip microcomputer to realize the measurement of the instantaneous flow rate and the total flow rate of the accumulated liquid.
[0027] Figure 3 This is a schematic diagram of the information transmission and function realization between the 51 single-chip microcomputer system and the host computer. The speed and number of revolutions of the flow meter are measured through the measuring device. The ambient temperature and humidity are measured through DH11. The current instantaneous flow and total flow are displayed through the LCD1602 of the 51 single-chip microcomputer control system at the current time. During the information transmission process, the information transmission between the 51 single-chip microcomputer and the host computer is realized through the wifi or Bluetooth module. The threshold value can be set in the host computer. The most suitable value of the ambient temperature and humidity, as well as the flow limit, can be set. When the flow exceeds the threshold, the 51 single-chip microcomputer control system will realize the sound and light alarm in the ward. At the same time, the display part of the host computer also displays the current bed number and sends out the sound and light alarm. The host computer can also pay attention to the patient's real-time condition. The storage module set in the host computer can realize the statistics of patient drainage flow and reduce the workload of nurses.
[0028] Figure 4 This is the connection form between the flow meter and the 51 single-chip microcomputer control system. Through the connection device, the single-chip microcomputer records the instantaneous speed and total number of revolutions of the current flow meter, and the current accurate flow rate can be obtained after conversion.
[0029] The present invention and its embodiments are described above. This description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs structures and embodiments similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
