DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] like Figures 1 to 4 As shown, the present invention provides an automatic measurement and monitoring system for postoperative drainage fluid of patients, including: an optical detection cabin 1, and a weighing component 2 arranged at the upper end of the optical detection cabin 1, the drainage tube is passed through the weighing component 2, and the drainage bag 8 is hung on the weighing component 2 to measure the weight of the drainage bag 8.

[0020] A monitoring module 3 for identifying the color and turbidity of the drainage fluid in the drainage bag 8 is installed in the optical detection cabin 1 .

[0021] The weight measuring assembly 2 and the monitoring module 3 are connected with a processing module 4, and the processing module 4 sends the output data of the weight measuring assembly 2 and the monitoring module 3 to the cloud platform 6 through a wireless communication module 5, the processing module 4 is connected with an alarm 7, and the cloud platform 6 processes the output data of the weight measuring assembly 2 and sends a control instruction to the processing module 4 to control the alarm 7 to perform the alarm work.

[0022] In the embodiment, the intelligent weight measuring assembly and the intelligent monitoring module for monitoring and identifying the color and turbidity of the drainage liquid are specifically used, the drainage weight and the state of the drainage liquid can be monitored in real time, the drainage liquid volume does not need to be recorded manually, and the color / turbidity does not need to be judged by the naked eyes of the medical staff, and the accuracy of synchronously monitoring the drainage weight, color, turbidity and flow rate is improved.

[0023] Preferably, the weight measuring assembly 2 is installed at the upper end of the optical detection cabin 1, and the drainage bag 8 is hung on the weight measuring assembly 2, so that the drainage bag 8 is in a suspended state when the weight of the drainage bag 8 is measured, thereby reducing the weight measurement error caused by the contact between the cabin body of the optical detection cabin 1 and the drainage bag 8.

[0024] If the weight measuring assembly 2 is arranged at the bottom of the optical detection cabin 1, for example, an electronic scale is arranged at the bottom of the optical detection cabin 1, and the bottom surface area of the drainage bag 8 is small, the drainage bag 8 is easily inclined in the optical detection cabin 1, thereby affecting the continuous performance of the drainage work and causing a large weight measurement error of the drainage bag 8.

[0025] And the present embodiment specifically uses the spring force principle to prepare the dynamometer, and the object is hung vertically by the dynamometer. When the spring dynamometer and the object are both static, it indicates that the object is subjected to the HYPERLINK "https: / / baike.baidu.com / item / %E5%B9%B3%E8%A1%A1%E5%8A%9B / 2158032?fromModule=lemma_inlink" \t "https: / / baike.baidu.com / item / %E6%B5%8B%E5%8A%9B%E8%AE%A1 / _blank" balanced force, i.e. the HYPERLINK "https: / / baike.baidu.com / item / %E9%87%8D%E5%8A%9B / 274830?fromModule=lemma_inlink" \t "https: / / baike.baidu.com / item / %E6%B5%8B%E5%8A%9B%E8%AE%A1 / _blank" gravity and the pulling force are a pair of balanced forces and the size is equal. The pulling force of the object to the dynamometer and the pulling force of the dynamometer to the object are the action force and the reaction force, and the size is equal. Therefore, the reading is the gravity of the measured object. The vertically distributed drainage bag 8 can ensure the smooth progress of the drainage work and avoid the problem of drainage pipe blockage caused by the bending of the drainage bag 8. Moreover, the drainage bag 8 can maintain vertical distribution and does not contact the optical detection cabin 1, thereby improving the accuracy of weight measurement.

[0026] As shown in Figure 1 and Figure 2 , the weight measuring assembly 2 includes a cover plate 21 hinged to the upper end of the optical detection cabin 1, and a digital dynamometer 22 arranged on the cover plate 21. The drainage bag 8 is hung on the digital dynamometer 22, and the weight of the drainage liquid in the drainage bag 8 is monitored in real time by the digital dynamometer 22.

[0027] The cover plate 21 is provided with a slotted hole 23 opening to the side surface thereof, and the drainage tube of the drainage bag 8 is arranged in the slotted hole 23.

[0028] The aperture of the slotted hole groove 23 is larger than the diameter of the drainage tube, and the digital tension meter 22 is at least two, and the distribution direction of the digital tension meter 22 is perpendicular to the slotted hole groove 23.

[0029] The upper end surface of the cover plate 21 is provided with a weight display panel 24 connected with the digital tension meter 22 to display the weight of the drainage bag 8 measured by the digital tension meter 22.

[0030] The digital tension meter 22 used in the embodiment can be selected as a WD digital tension meter WDF portable digital spring dynamometer tension meter. The digital tension meter 22 is installed on the cover plate 21 and the hanging buckle is exposed. The drainage bag 8 can be hung on the digital tension meter 22 and vertically distributed.

[0031] The upper end of the drainage bag 8 is provided with two perforations 81 symmetrically distributed with respect to the drainage tube. The drainage bag 8 is hung on the digital tension meter 22 through the perforations 81. The cabin diameter of the optical detection cabin 1 is larger than the width of the drainage bag 8, and the height of the optical detection cabin 1 is larger than the moving distance of the digital tension meter 22 corresponding to the maximum containing volume in the drainage bag 8, so that the drainage bag 8 hung on the digital tension meter 22 has no other supporting effect.

[0032] It should be particularly noted that in order to intelligently monitor the drainage volume of the drainage liquid in real time, the digital tension meter 22 is used as a weighing component to calculate the weight change of the drainage liquid per unit time, so as to dynamically calculate the flow rate of the drainage liquid through the weighing data. At this time, when the drainage tube is pulled, the weighing weight of the digital tension meter 22 will abnormally change. For example, when the drainage tube is pulled upward by mistake, the weighing weight of the digital tension meter 22 will decrease, which will cause abnormal situation of the processing result of the cloud platform 6 and affect the real-time monitoring of the drainage liquid.

[0033] In order to solve the above problem, the inner end of the slotted hole groove 23 is provided with a pipe body fixing component 9. The pipe body fixing component 9 is used to fix the drainage tube when the drainage tube moves upward, so as to prevent the drainage bag 8 from being pulled upward and causing measurement error of the digital tension meter 22.

[0034] As shown in Figure 3 The pipe body fixing component 9 includes inclined rotating gears 91 distributed on both sides of the slotted hole groove 23. The center position of the inclined rotating gears 91 is movably installed in the cavity plate 92. The side surface of the cavity plate 92 facing the drainage tube is open. The cavity plate 92 movably installs a spring plate 93.

[0035] When the amount of drainage liquid in the drainage bag 8 gradually increases, the drainage tube moves downward and drives one of the two inclined rotating gears 91 to rotate in the positive direction and the other to rotate in the negative direction, and the elastic plate 93 keeps bouncing when the inclined rotating gears 91 rotate.

[0036] When the drainage tube moves upward, it drives one of the two inclined rotating gears 91 to rotate in the negative direction and the other to rotate in the positive direction, and the elastic plate 93 abuts against the adjacent two tooth plates of the inclined rotating gears 91 to prevent the inclined rotating gears 91 from rotating.

[0037] When the postoperative drainage liquid automatic measurement monitoring system of the present embodiment is used, the distribution line of the drainage tube needs to be fixed without any obstruction, and then the tube fixing assembly 9 is arranged on the cover plate 21 at the upper end of the optical detection cabin 1, which can ensure that the drainage bag can only move downward and cannot move upward, thereby ensuring the normal weighing work of the digital tension meter 22.

[0038] When the drainage liquid continuously moves into the drainage bag 8 through the drainage tube, the drainage bag 8 will deform the spring and move downward in the optical detection cabin 1, and correspondingly, the drainage tube will also move downward. At this time, the drainage tube just contacts the surface of the inclined rotating gear 91, and the inclined rotating gear 91 is driven by the drainage tube to rotate in the positive direction. When the drainage tube is pulled upward, the inclined rotating gear 91 is driven to rotate in the negative direction, and the inclined rotating gear 91 is abutted by the elastic plate 93 and cannot rotate, thereby fixing the drainage tube and avoiding the continuous upward movement of the drainage tube.

[0039] In addition, the processing module 4 is connected with the alarm 7, and the cloud platform 6 processes the output data of the weighing assembly 2 and sends a control instruction to the processing module 4 to control the alarm 7 to perform the alarm work. When the cloud platform 6 monitors that the output data of the weighing assembly 2 decreases in the monitoring period, it sends an alarm instruction to the processing module 4, and the processing module 4 controls the alarm 7 to perform the alarm work, reminding the abnormal upward movement of the drainage tube.

[0040] In addition, as shown in Figure 2 Further, the upper end of the optical detection cabin 1 is provided with an incandescent lamp 10 for illuminating the drainage bag 8, and the monitoring module 3 includes an RGB sensor 31 for identifying the color of the drainage liquid in the drainage bag 8 and a near-infrared spectrum module 32 for identifying the turbidity of the drainage liquid in the drainage bag 8.

[0041] The RGB sensor 31 can detect and identify the light intensity of red, green and blue three primary colors, and the cloud platform 6 is provided with red, green and blue three primary color thresholds, and the cloud platform 6 compares the red, green and blue three primary color light intensities monitored by the RGB sensor 31 in real time with the red, green and blue three primary color thresholds to monitor whether the color of the drainage liquid meets the setting.

[0042] The near infrared spectroscopy module 32 emits near infrared light, and the near infrared light passes through the sample and is measured by the spectrometer detector to identify the turbidity of the drainage fluid.

[0043] like Figure 1 As shown, the inner curved surface of the optical detection cabin 1 is made of opaque material and is set as a reflective surface. A vertically distributed observation window 11 is provided on the side curved surface of the optical detection cabin 1, and the drainage fluid volume in the drainage bag 8 is read through the observation window 11.

[0044] An RGB sensor is a sensor that can detect and identify the intensity of the three primary colors of light: red, green, and blue. RGB represents the three basic colors of light, red, green, and blue. Through different combinations and intensities, these colors can create the vast majority of colors perceived by human vision. An RGB sensor uses built-in photoelectric conversion elements to convert these light signals into electrical signals, which can then be recognized and processed by electronic devices.

[0045] The operating principle of an RGB sensor is primarily based on the photoelectric effect. When light strikes the sensor, the photoelectric conversion element within the sensor (such as a photodiode or photoresistor) absorbs the energy of the photon, causing electrons to transition from a bound state to a free state, generating a photocurrent. The intensity of this photocurrent is proportional to the intensity of the light striking the sensor.

[0046] Therefore, an RGB sensor typically contains three independent photosensors, one for red, green, and blue. When the RGB sensor is operating, it emits detection light toward the drainage bag. This light is reflected by each photosensitive element, which generates a different photocurrent based on the intensity of the corresponding color. By measuring these photocurrents, the RGB components of the incident light can be determined, thereby restoring the original color information.

[0047] Wherein, R component is 0-255, G component is 0-255, B component is 0-255, the color of the liquid flowing out of the drainage tube after surgery may vary depending on the specific type of surgery, postoperative time and individual differences, generally clear or light yellow outflow fluid is a normal phenomenon, usually mixed with the HYPERLINK "https: / / m.baidu.com / bd_page_type=1 / baiduid=B92EB17E6EA42996B7E348CC85D66B81 / t=mip / l=1 / tc?ct=54&lid=41924502018166&module=mip&eqid=c189bd3d004a234e000000056858f28e&cst=55&clk_extra={"pageid":"41924502018166","searchID":"41924502018166","nPageID":"41924502018166","mip_logid":"41924502018166","masterpage_type":"self","originalUrl":"http:\\ / \\ / muzhi.baidu.com\\ / content_production\\ / fine_422498776297728.html","srcid":"landingpage","name":"\\u81ea\\u5efa\\u9875highlight","id":"highlight"}&sec=4497&di=3474e1f0d1d2ff0e&&bdver=2_1&bdenc=1&nsrc= / OPkEndSS1OxJGcxb+QxS4jhudfWfcVQ9kamXIo3uFjQ2m214nYCYEE58xBztsdDC0G80bNw / eeFm+nN5PwfLcA / j35o82mqT6KX2hjACyUUHEDyxZDGYqs0WGh5jAJQTh1VS9gF7RtOwNlEBzuiGtnW7EHd74HxpNtA / / B / IDg7hYyYg8UmhMLSnYeoqvKDinXpf9Y75TtMBLLKbagOP6hcft0yNTMhwuokW3F / Msw=" saline or other washing liquid, and some lymph fluid. The color of the liquid shows that the surgical site is normal in the healing process of waste discharge.

[0048] When the drainage fluid is pink or light red, it can indicate that there is a certain amount of blood in the drainage fluid. In the early postoperative period, this can be normal, with a small amount of bleeding due to trauma at the surgical site. However, if the color remains red for a long time or the amount of drainage fluid increases, it may be necessary to seek medical attention for evaluation.

[0049] When the drainage fluid is dark red or bright red, it can indicate that there is a large amount of fresh blood in the drainage fluid, which requires immediate medical attention from a doctor, as it can be a sign of abnormal bleeding.

[0050] When the drainage fluid is yellow-green or brown, it can be due to the presence of bile (yellow-green) or other digestive fluids (brown) in the drainage fluid, which can indicate that the surgery has affected the biliary tract or related organs. If such liquid color appears, please contact the doctor in time.

[0051] When the drainage fluid is milky white, the milky white liquid can be a sign of chylo leakage, which can be due to damage to the thoracic duct or abdominal lymphatic vessels during surgery. This condition may require special treatment, such as fasting and total parenteral nutrition.

[0052] Therefore, the threshold range of R component, G component and B component corresponding to clear and light yellow drainage fluid, when exceeding the threshold range of R component, G component and B component, it means that there is a problem, which needs to be handled in time.

[0053] Further, the cloud platform 6 is provided with a flow calculation unit 61, which is used to calculate the increase in drainage fluid in a unit of time to represent the dynamic flow rate of the drainage tube, wherein the increase in drainage fluid is the change in the weight of the drainage bag 8 measured by the digital tension gauge 22.

[0054] The cloud platform 6 is provided with a flow rate threshold range, and the cloud platform 6 controls the alarm 7 to perform alarm work when the dynamic flow rate of the drainage tube exceeds the flow rate threshold range.

[0055] Assuming that the initial value of the weight of the drainage bag 8 measured by the digital tension gauge 22 is a, and the weight of the drainage bag 8 measured by the digital tension gauge 22 is b as the drainage proceeds for time t, the increase in drainage fluid is b-a, and the dynamic flow rate of the drainage tube is b-a / t, when the dynamic flow rate of the drainage tube exceeds the flow rate threshold range, i.e. the flow rate is too large or too small, the cloud platform 6 controls the medical staff.

[0056] In this embodiment, the cloud platform 6 is also provided with a timing unit, which is used to calculate the numerical change of the increase in drainage fluid and the numerical state of the RGB component, so as to calculate the length of time that the drainage fluid maintains a low dynamic flow rate, for example, the flow rate <5mL / h for 2h+, to remind the medical staff of the warning.

[0057] In order to avoid the interference phenomenon of the monitoring work of the RGB sensor 31 and the near-infrared spectrum module 32, the RGB sensor 31 and the near-infrared spectrum module 32 are alternately controlled. The processing module 4 controls the RGB sensor 31 and the near-infrared spectrum module 32 to work alternately, and the time interval between adjacent two times of monitoring the color of the drainage fluid by the RGB sensor 31 is the same as the time interval between adjacent two times of monitoring the turbidity of the drainage fluid by the near-infrared spectrum module 32.

[0058] The monitoring method of the postoperative drainage fluid automatic measurement monitoring system for the patient includes the following steps: The drainage bag is hung on the weighing unit in the optical detection cabin, the initial value of the weighing unit is set, and the weight of the drainage fluid in the drainage bag is monitored in real time; The flow rate of the drainage fluid and the flow rate maintenance time are calculated in combination with the weight change of the drainage fluid in the drainage bag, the medical and nursing end early warning work is performed based on the flow rate of the drainage fluid and the flow rate maintenance time, and the patient end alarm work is performed when the flow rate of the drainage fluid is negative, so as to avoid that the patient pulls the drainage bag; The color and turbidity of the drainage fluid in the drainage bag are alternately monitored at fixed interval time, and the medical and nursing end early warning work is performed based on the color and turbidity of the drainage fluid; The flow rate, flow rate maintenance time and patient state of the drainage fluid are recorded, and the correlation between the drainage and the patient state is constructed, for example, the relationship between the patient sitting position and the drainage flow rate.

[0059] The embodiment provides a patient management system based on postoperative drainage fluid measurement, which can monitor the rate, color and turbidity of postoperative drainage in real time to indicate the health status of the patient after surgery, can locally analyze and compare with cloud big data in real time, improve the early warning accuracy, break through the limitation of single weight detection, and realize the synchronous analysis of "drainage volume-drainage turbidity quality-drainage color".

[0060] When the above system is applied to a patient ward, the following two embodiments are obtained: Embodiment 1: Postoperative management of abdominal drainage The device card slot fixes the abdominal drainage tube, and the initial parameters are set: alarm threshold: flow rate > 100 mL / h or color_R > 180.

[0061] Postoperative detection at 8 hours: The flow rate suddenly increases to 135 mL / h, the color_R value rises to 210, the system triggers a red alarm, and pushes a CT examination suggestion to the mobile phone of the attending doctor.

[0062] After active bleeding is diagnosed, the system automatically records the event and associates the electronic medical record.

[0063] Embodiment 2: Thoracic drainage behavior guidance It is found by analysis that the drainage flow rate of the patient decreases by > 40% from 10:00 to 12:00 every day.

[0064] Retrieving contemporaneous data finds that the patient position training time coincides.

[0065] System generates "position adjustment recommendation": reduce the drainage bottle by 15 cm in the sitting position.

[0066] The above examples are only exemplary embodiments of the present application and are not intended to limit the present application, and the protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the present application within the spirit and protection scope of the present application, and such modifications or equivalent replacements shall also be considered to fall within the protection scope of the present application.
