Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly, to an intra-abdominal pressure detection device and a detection method. Background Art

[0002] With the clinical application and the research of many domestic clinical experts, the monitoring of intra-abdominal hypertension (IAH) has extensive clinical significance in the ICU monitoring. The evolution speed and process of IAH to abdominal compartment syndrome (ACS) vary greatly among different patients. Among them, the speed of IAH developing into ACS is the fastest in patients with fulminant pancreatitis. The patient can enter the ACS stage through the IAH stage within a few hours to 48 hours after the onset of SAP. The increase in intra-abdominal pressure IAH is closely related to the incidence and mortality of ACS. To minimize the risk of ACS development, it is completely necessary to actively measure the intra-abdominal pressure of high-risk patients, pay attention to the change trend of IAH, and quickly intervene before the occurrence of ACS, which can significantly reduce the incidence and mortality of ACS.

[0003] Clinical studies have shown that the measurement of bladder pressure not only has non-invasiveness, but also has a significant linear positive correlation with intra-abdominal pressure. It has characteristics such as high detection accuracy and good correlation, and is widely used in clinical practice. It is currently recognized as the "gold standard" for indirectly measuring intra-abdominal pressure (IAP).

[0004] However, in the prior art, the detection of bladder pressure often requires the operator to operate manually. For some patients who need to monitor the intra-abdominal pressure periodically and frequently for a period of time, especially at night, medical staff need to perform operations frequently, which is time-consuming and laborious and has low efficiency.

[0081] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are only for illustrative purposes and are not used to limit the scope of these messages or information.

[0082] The present disclosure will be described in detail below with reference to the drawings and in combination with embodiments.

[0083] As Figures 1 to 3As shown in the figure, the intra-abdominal pressure detection device of an embodiment of the present application mainly includes: an input bag 100 for storing physiological saline; a syringe 200 for providing the power for the flow of physiological saline; a pressure sensor 300 for recording pressure values; an execution device 500. The execution device 500 includes a connecting member 510. The input bag 100, the syringe 200, and the pressure sensor 300 are respectively connected to the connecting member 510 through pipelines. The execution device 500 further includes a first electromagnetic valve 520, a second electromagnetic valve 530, and a third electromagnetic valve 540. A first electromagnetic valve 520 is provided in the pipeline between the input bag 100 and the connecting member 510. A second electromagnetic valve 530 is provided in the connecting pipeline between the syringe 200 and the connecting member 510. A third electromagnetic valve 540 is provided in the connecting pipeline between the pressure sensor 300 and the connecting member 510. First connection ports and second connection ports are further provided at both ends of the connecting member 510. The first connection port is connected to a urinary catheter through a pipeline, and the second connection port is connected to a liquid storage member through a pipeline. Wherein, the first electromagnetic valve 520, the second electromagnetic valve 530, and the third electromagnetic valve 540 are used to realize the conduction and closing of the connecting member 510 and each pipeline according to the input electrical signal. The intra-abdominal pressure detection device further includes: a collection device 600 for acquiring the operation state signal of the detection device; a control device 400 for sending a control signal to the execution device 500 according to the state signal sent by the collection device 600 to control the execution device 500. Wherein, the collection device 600 includes an image capturing device 610, and the control device 400 sends a control signal to the execution device 500 according to the image signal collected by the image capturing device 610 to control the execution device 500.

[0084] Specifically, the input bag 100 is filled with physiological saline, and its outlet end is connected with a pipeline, and the other end of the pipeline is fixedly connected to the connecting member 510. The syringe 200 is connected to the connecting member 510 through a pipeline. When both the first electromagnetic valve 520 and the second electromagnetic valve 530 are in the open state, the physiological saline in the input bag 100 can be sucked into the syringe 200 by pulling the syringe 200. Then, by closing the first electromagnetic valve 520, the syringe 200 is connected to the urinary catheter, and then by pushing the syringe 200, a certain amount of physiological saline can be injected into the bladder through the urinary catheter. Then, when the second electromagnetic valve 530 is closed and the third electromagnetic valve 540 is opened, the physiological saline in the bladder can enter the pressure sensor 300 through the pipeline. Furthermore, the value displayed in the pressure sensor 300 is the pressure inside the bladder at this time, and the intra-abdominal pressure can be obtained through conversion.

[0085] More specifically, the first solenoid valve 520, the second solenoid valve 530, and the third solenoid valve 540 are all electrically connected to the control device 400, and the control device 400 can send electrical signals to open and close the first solenoid valve 520, the second solenoid valve 530, and the third solenoid valve 540. The control device 400 is a chip in the prior art that can implement the above functions.

[0086] The acquisition device 600 is used by the user to obtain the operating state signal of the detection device. The operating state signal referred to here is the signal generated by the intra-abdominal pressure detection device during normal operation. Specifically, the operating state signal of the detection device includes: the flow rate signal of the liquid in the pipeline between the input bag 100 and the connecting member 510; the flow rate signal of the liquid in the pipeline between the syringe 200 and the connecting member 510; the flow rate signal of the liquid in the pipeline between the pressure sensor 300 and the connecting member 510; the flow rate signal of the liquid in the pipeline between the catheter and the first connection port. Flow meters 620 are provided in the pipelines between the input bag 100 and the connecting member 510, between the syringe 200 and the connecting member 510, between the pressure sensor 300 and the connecting member 510, and between the catheter and the first connection port. During the detection process of the intra-abdominal pressure detection device, the flow meter 620 will send its own flow data to the control device 400 in real time. When the flow meter 620 in a certain pipeline detects an abnormal flow rate, it means that the pipeline at that place has suffered from conditions such as kinking or fracture. At this time, the control device 400 can control the first solenoid valve 520, the second solenoid valve 530, and the third solenoid valve 540 to close in time to interrupt the detection of bladder pressure. That is, the control device 400 sends a control signal to the actuator 500 to control the actuator 500 according to the flow rate signal of the liquid in the pipeline between the input bag 100 and the connecting member 510, and / or the flow rate signal of the liquid in the pipeline between the syringe 200 and the connecting member 510, and / or the flow rate signal of the liquid in the pipeline between the pressure sensor 300 and the connecting member 510, and / or the flow rate signal of the liquid in the pipeline between the catheter and the first connection port.

[0087] In a specific embodiment, the intra-abdominal pressure detection device further includes a temperature control device 400. The temperature control device 400 is disposed between the catheter and the first connection port. The temperature control device 400 includes a temperature detection device 630 and a heating device 800. The control device 400 sends an electrical signal to the heating device 800 according to the control signal sent by the temperature detection device 630 to heat the liquid in the catheter. When the intra-abdominal pressure detection device injects physiological saline into the bladder of the subject to be measured, if the temperature of the physiological saline is relatively low, it will cause irritation to the bladder when injected into the bladder of the subject to be measured, which will in turn cause the bladder muscles to contract, and further make the measured value of the pressure in the bladder inaccurate. Therefore, to solve this problem, a temperature detection device 630 and a heating device 800 are provided in the pipeline between the catheter and the connecting member 510. The temperature detection device 630 sends the specific temperature information of the liquid flowing through the pipeline to the control device 400. After calculation and judgment, the control device 400 sends a control signal to the heating device 800 or the execution device 500 to avoid the inaccuracy of the measured temperature caused by the too low temperature of the physiological saline flowing into the bladder of the subject to be measured.

[0088] In a specific embodiment, the intra-abdominal pressure detection device further includes a pressure sensor moving solenoid valve 560, which is used to move the position of the pressure sensor 300 according to the input electrical signal; wherein, the control device 400 sends a control signal to the pressure sensor moving solenoid valve 560 according to the image signal collected by the image capturing device 610 to move the pressure sensor 300. The image capturing device 610 captures an image of the subject to be measured. Then, the control device 400 determines whether the position coordinates of the upper edge of the pubic symphysis and the reference position coordinates of the pressure sensor 300 are on the same horizontal plane in the horizontal direction according to the captured image. If they are not on the same horizontal plane, the control device 400 controls the pressure sensor moving solenoid valve 560 to move the pressure sensor 300 so that the pressure sensor 300 actively aligns with the position of the upper edge of the pubic symphysis, ensuring the accuracy of the finally measured intra-bladder pressure data.

[0089] In a specific embodiment, the intra-abdominal pressure detection device further includes an interaction device 700, which is used for the user to operate to achieve human-computer interaction operations; wherein, the control device 400 sends a control signal to the execution device 500 according to the control signal sent by the interaction device 700.

[0090] The interaction device 700 is mainly used to provide a human-computer interaction interface for the user to set data, and at the same time, it also feeds back various data received by the control device 400 to the user. As a specific solution, the interaction device 700 can adopt a touch display with a processing chip and a memory. The touch screen of the touch display can be used for both display and for the user to input data by touch. The user can achieve human-computer interaction by operating the instructions on the touch screen. Using the touch screen as the carrier of the interaction module improves the intelligence level of human-computer interaction and reduces the operation difficulty.

[0091] Specifically, the interaction device 700 includes: a first interaction module 710 for the user to operate to start or close the intra-abdominal pressure detection; wherein, the control device 400 sends a control signal to the execution device 500 according to the control signal sent by the first interaction module 710. The interaction device 700 further includes: a second interaction module 720 for the user to operate to display the intra-abdominal pressure detection result; wherein, the control device 400 sends a control signal to the second interaction module 720 according to the control signal sent by the pressure sensor 300.

[0092] More specifically, the operator starts and closes the intra-abdominal pressure detection through the first interaction module 710 and can set the operation frequency and operation specifications through the first interaction module 710. The control device 400 sends an electrical signal to the execution device 500 according to the control signal sent by the first interaction module 710 to start the intra-abdominal pressure detection. The execution device 500 further includes a telescopic rod 550 for advancing the syringe 200 according to the received electrical signal; wherein, the control device 400 sends a control signal to the telescopic rod 550 according to the electrical signal sent by the acquisition device 600 to control the syringe 200. That is, after the control device 400 receives the control signal sent by the first interaction module 710, it sends a power-on start signal to the first solenoid valve 520, the second solenoid valve 530, the third solenoid valve 540, the telescopic rod 550, and the acquisition device 600.

[0093] As an intra-abdominal pressure detection method according to another embodiment of the present application, which is used to implement the intra-abdominal pressure detection, the intra-abdominal pressure detection method is implemented by the above-mentioned intra-abdominal pressure detection device, and the intra-abdominal pressure detection method includes:

[0094] S100. In response to the status signal of the intra-abdominal pressure detection device collected by the acquisition device 600, obtain the operating status of the intra-abdominal pressure detection device in the current state;

[0095] S200. When the flow rate signal of the liquid in the pipeline between the input bag 100 and the connecting member 510, and / or the flow rate signal of the liquid in the pipeline between the syringe 200 and the connecting member 510, and / or the flow rate signal of the liquid in the pipeline between the pressure sensor 300 and the connecting member 510, and / or the flow rate signal of the liquid in the pipeline between the urinary catheter and the first connection port is lower than the preset flow rate, a control signal to close is sent to the first solenoid valve 520, the second solenoid valve 530, and the third solenoid valve 540.

[0096] Specifically, flow meters 620 are provided in the pipelines between the input bag 100 and the connecting member 510, between the syringe 200 and the connecting member 510, between the pressure sensor 300 and the connecting member 510, and between the urinary catheter and the first connection port. During the process of the intra-abdominal pressure detection device performing detection, the flow meters 620 will send their own flow rate data to the control device 400 in real time. When the flow meter 620 in a certain pipeline detects abnormal flow rate, it indicates that the pipeline at that place has problems such as being pressed or broken. At this time, the control device 400 can control the first solenoid valve 520, the second solenoid valve 530, and the third solenoid valve 540 to close in time, thereby interrupting the detection of bladder pressure.

[0097] S300. In response to the control signal sent by the temperature detection device 630, obtain the temperature t of the physiological saline in the pipeline between the urinary catheter and the first connection port.

[0098] S400. When the value range of the temperature t is between t0 and t1, a control signal is sent to the heating device 800 to cause the heating device 800 to heat the physiological saline in the pipeline between the urinary catheter and the first connection port until the temperature t is higher than t1 and then stop.

[0099] Specifically, the heating device 800 is arranged at one end of the pipeline far from the urinary catheter. When t0 < t < t1, the heating device 800 can heat it to the temperature t1, and the temperature t1 is slightly higher than the temperature of the urine in the bladder.

[0100] S500. When the value range of the temperature t is less than t0, a control signal to close is sent to the first solenoid valve 520, the second solenoid valve 530, and the third solenoid valve 540.

[0101] When t < t0, it indicates that the temperature of the physiological saline is much lower than the most suitable temperature t1 at this time. Therefore, the heating device 800 cannot heat the physiological saline to t1 in a short time. Thus, the control device 400 sends a control signal to close the first solenoid valve 520, the second solenoid valve 530, and the third solenoid valve 540, and this measurement is terminated.

[0102] The intra-abdominal pressure detection method further includes:

[0103] S600. In response to the image signal collected by the image capturing device 610, obtain the coordinate information of the upper edge position of the symphysis pubis of the object to be measured;

[0104] S700. When the coordinate information of the upper edge position of the symphysis pubis of the object to be measured and the reference point coordinates of the pressure sensor 300 are not on the same horizontal line, send a control signal to the moving solenoid valve 560 of the pressure sensor to move the pressure sensor 300 by the moving solenoid valve 560 until the coordinate information of the upper edge position of the symphysis pubis of the object to be measured and the reference point coordinates of the pressure sensor 300 are on the same horizontal line.

[0105] The intra-abdominal pressure detection method further includes:

[0106] S800. The image capturing device 610 collects the displacement amount between the body position of the object to be measured and the preset standard body position. When the displacement amount exceeds the preset reference value, the control device 400 sends a control signal to the interaction device 700 and marks the measurement result of this time;

[0107] S900. When the displacement amount exceeds the preset reference value and the measurement cycle reaches 3 times, the control device 400 sends a control signal to close the first solenoid valve 520, the second solenoid valve 530, and the third solenoid valve 540, and simultaneously sends an alarm message to the interaction device 700.

[0108] Specifically, to ensure the accuracy of the measurement, the body position of the object to be measured is crucial. When lying completely flat, the abdominal muscles may contract involuntarily, while the semi-recumbent position can relax the abdominal muscles and more accurately reflect the true pressure of the bladder. Therefore, generally, the semi-recumbent position is adopted, and a Foley catheter is placed for urinary catheterization to empty the bladder. During the detection process, it is necessary to keep the posture stable and avoid movement or coughing (which may cause pressure fluctuations). Therefore, when the displacement amount between the body position of the object to be measured collected by the image capturing device 610 and the preset standard body position is greater than the set value, it indicates that the object to be measured has moved at this time. When the displacement amount is large, it is possible that the object to be measured is not in the semi-recumbent position, and the finally measured value is not an accurate value.

[0109] Among them, the method for the image capturing device 610 to collect the body position of the object to be measured includes:

[0110] Place 4 marking points at the fixed position of the object to be measured. The 4 marking points are located in the lower abdomen of the object to be measured, and one of them is located at the upper edge position of the symphysis pubis.

[0111] Collect a standard body position image of the object to be measured under the illumination of a visible light source, mark the coordinates (a, b, c, d) of the marking points in the image, and obtain the regional image R0 of the object to be measured as a template. The template is used to locate the positions of the marking points of the object to be detected in the subsequent steps.

[0112] Collect an image of the object to be measured under the illumination of a visible light source, and take the area to be recognized (a - r, b - r, c + r, d + r), where (a, b, c, d) are parameters in template making, and r is a configuration parameter (from 1 to 5), to obtain an image Ri of the marked points of the object to be measured. When the weight of the object to be measured is large, a larger value of r is taken to reduce false alarms. When the weight of the object to be measured is small, a smaller value of r is taken for higher precision.

[0113] Slide a window of R0 on Ri, and calculate the matching similarity γ between R0 and Ri. The calculation method is the matching value of R0 on the window image of Ri:

[0114] ,

[0115] where m represents the pixel coordinate index in the image, represents the pixel value at this coordinate in R0, represents the pixel value at this coordinate in Ri;

[0116] When the matching similarity γ is greater than the preset value, it indicates that the displacement between the body position of the object to be measured and the preset standard body position is greater than the preset reference value.
