Description

Technical Field

[0001] This application relates to the field of pneumoperitoneum testing technology, and in particular to a pneumoperitoneum testing device. Background Technology

[0002] An insufflator is a specialized device used in laparoscopic surgery to establish and maintain pneumoperitoneum. It mainly consists of an inlet tube, a main unit, an outlet tube, and an insufflation needle.

[0003] The working principle of an insufflator is mainly based on gas as a medium. As gas is injected, the abdominal wall is slowly lifted, forming a cavity, which is called "pneumoperitoneum". Current related technologies use ordinary balloons to simulate the abdominal cavity for testing the insufflator, and the elastic modulus of an ordinary balloon is approximately 0.225 L / Pa.

[0004] The above-mentioned method of using ordinary balloons to simulate the abdominal cavity for testing the insufflator is inaccurate because the elastic modulus of ordinary balloons differs significantly from that of the actual abdominal cavity. Summary of the Invention

[0005] To address the problem of inaccurate performance testing results of insufflator machines caused by using ordinary balloons to simulate the abdominal cavity in related technologies, this application provides an insufflator machine testing device, employing the following technical solution: It includes a housing for simulating the abdominal cavity, the housing containing liquid, and the housing comprising a first container, a second container, and a third container. The first and second containers are connected, as are the second and third containers. The third container is equipped with a pressure detection component for detecting pressure values. The insufflator machine is connected to the third container, and a flow detection component for detecting the actual flow rate of the insufflator machine is provided between the third container and the output end of the insufflator machine.

[0006] In one specific implementation scheme, the box body is provided with a first partition, which divides the box body into a third compartment and a separate compartment. The separate compartment is provided with a second partition, which divides the separate compartment into a first compartment and a second compartment.

[0007] In one specific implementation, a push hole is provided on the third container, and a push plate matching the third container is slidably connected inside the third container. A push rod matching the push hole is provided on the surface of the push plate facing the push hole. The push rod is slidably connected inside the push hole and partially passes through the push hole. A sealing assembly is provided between the push plate and the third container.

[0008] In one specific implementation, the number of push holes and push rods is set to two, and the two push rods are located on the same straight line in the vertical direction.

[0009] In one specific implementation, the outer edge of the push rod is provided with scale values.

[0010] In one specific implementation, the third container is equipped with an air pump for inflating the interior of the third container.

[0011] In one specific implementation scheme, the third container is provided with a vent valve to control the pressure inside the third container.

[0012] In a specific implementation scheme, the system further includes a data acquisition module and a data processing module. The data acquisition module is used to acquire detection information from the pressure detection component and the flow detection component and feed the detection information back to the data processing module. The data processing module is used to receive the detection information from the data acquisition module, process and summarize it, and send the summarized detection information to the control center in real time.

[0013] In one specific implementation, the data acquisition module includes a pressure acquisition submodule and a flow acquisition submodule. The pressure acquisition submodule is used to acquire the detection information of the pressure detection component and feed the detection information back to the data processing module. The flow acquisition submodule is used to acquire the detection information of the flow detection component and feed the detection information back to the data processing module.

[0014] In one specific implementation scheme, the data processing module includes a pressure processing submodule and a flow processing submodule. The pressure processing submodule is used to receive and process the detection information from the pressure acquisition submodule and send the processed detection information to the control center in real time. The flow processing submodule is used to receive and process the detection information from the flow acquisition submodule and send the processed detection information to the control center in real time.

[0015] In summary, this application has at least the following beneficial technical effects: In the initial state, the liquid fills the second and third containers, and the initial air pressure and initial volume of the insufflator detection device are zero when the insufflator is not inflated; when the insufflator is started, air is inflated into the third container, and some of the liquid in the third container is squeezed out into the second container by the gas. The excess liquid in the second container is discharged from the second container to the first container. At this time, there is a height difference between the liquid in the second and third containers. The pressure detection component and the flow detection component record the actual values ​​at this time. The actual values ​​are processed and summarized with the set values ​​of the insufflator, thereby realizing the detection of the performance of the insufflator. Intelligent measurement and calibration of the insufflator is realized through automated detection, which improves the accuracy of detecting the performance of the insufflator.

Detailed Implementation

[0020] The following is in conjunction with the appendix Figure 1-3 This application provides further details.

[0021] This application discloses a pneumoperitoneum testing device.

[0022] Reference Figure 1 and Figure 2 The pneumoperitoneum testing device includes a housing 1 for simulating an abdominal cavity. The housing 1 is connected to the air path of the pneumoperitoneum 24 and receives and contains the output gas of the pneumoperitoneum 24. The housing 1 is filled with liquid. In this embodiment, the housing 1 and the liquid structure are made of non-elastic material to simulate the abdominal cavity. Under normal temperature and pressure, the compatibility of carbon dioxide and water does not affect the test results. Therefore, the liquid used to simulate the abdominal cavity can be water.

[0023] Reference Figure 1 and Figure 2 The housing 1 includes a first container 2, a second container 3 and a third container 4. The first container 2 and the second container 3 can be connected through a second through hole 23. The second container 3 and the third container 4 can be connected through a first through hole 22. The top of the third container 4 is detachably connected to a first cover plate. The tops of the first container 2 and the second container 3 share a second cover plate and the second cover plate is detachably connected.

[0024] Reference Figure 1 and Figure 2The first cover plate of the third container 4 is provided with a pressure detection component for detecting pressure value. The insufflator 24 is connected to the third container 4 through a pipeline. A flow detection component for detecting the actual flow rate of the insufflator 24 is provided between the third container 4 and the output end of the insufflator 24. The first container 2 is provided with a water pumping component for drawing liquid from the first container 2 to the second container 3. In this embodiment, the pressure detection component is specifically a pressure gauge 19, the flow detection component is specifically a flow meter 20, and the water pumping component is specifically a water pump 21. The range of the pressure gauge 19 and the flow meter 20 covers the maximum actual air pressure and the maximum actual flow rate during measurement.

[0025] Therefore, in the initial state, the liquid fills the second container 3 and the third container 4. When the insufflator 24 is not inflated, the initial air pressure and initial volume of the insufflator 24 detection device are both zero. When the insufflator 24 is started, it inflates the third container 4. Some of the liquid in the third container 4 is squeezed out into the second container 3 by the gas. The excess liquid in the second container 3 is discharged to the first container 2. At this time, there is a height difference between the liquid in the second container 3 and the third container 4. The pressure detection component and the flow detection component record the actual values ​​at this time. The actual values ​​are processed and summarized with the set values ​​of the insufflator 24, thereby realizing the detection of the performance of the insufflator 24. Intelligent measurement and calibration of the insufflator 24 are realized through automated detection, which improves the accuracy of detecting the performance of the insufflator 24.

[0026] Reference Figure 1 and Figure 2 The third container 4 is equipped with an air pump 11 for quickly inflating the third container 4 in case of an accident. The top of the third container 4 is equipped with a vent valve 12 to control the pressure inside the third container 4, which can maintain the simulated intra-abdominal pressure or release the pressure, and the venting speed is adjustable.

[0027] Reference Figure 1 and Figure 2 The housing 1 is equipped with a first partition 5, which divides the housing 1 into a third compartment 4 and a secondary compartment 7. The secondary compartment 7 is equipped with a second partition 6, which divides the secondary compartment 7 into a first compartment 2 and a second compartment 3. In this embodiment, the first through hole 22 is located slightly lower on the first partition 5, while the second through hole 23 is located slightly upper on the second partition 6. The sum of the widths of the first compartment 2 and the second compartment 3 is equal to the length of the third compartment 4. Therefore, by optimizing the internal structural layout of the housing 1 using the first partition 5 and the second partition 6, compared to arranging the first compartment 2, the second compartment 3, and the third compartment 4 side-by-side, the usable space occupied by the housing 1 is reduced, and the space utilization rate is improved.

[0028] Reference Figure 1 and Figure 2Two push holes 8 are provided on the third container 4. A push plate 9 matching the size of the third container 4 is slidably connected inside the third container 4. Two cylindrical push rods 10 matching the size of the push holes 8 are fixedly connected to the surface of the push plate 9 facing the push holes 8. The two push rods 10 are vertically aligned on the same straight line. The push rods 10 are slidably connected inside the push holes 8 and partially pass through the push holes 8. The outer edge of the push rods 10 is provided with scale values. The scale values ​​are used to facilitate the operator to observe the position of the push plate 9 in the third container 4 when the push rods 10 are pushed. A sealing assembly is provided between the push plate 9 and the third container 4. In this embodiment, the outer edge of the push plate 9 is provided with a placement groove. The sealing assembly is specifically a sealing ring with an O-shaped cross section. The sealing ring is installed in the placement groove and partially extends out of the placement groove. The placement groove limits the position of the sealing ring and improves the stability of the sealing ring installation. Therefore, when the operator pushes the push rod 10, the push rod 10 moves the push plate 9. The surface of the push plate 9 away from the push rod 10 forms a cavity with the third container 4. The capacity of the cavity can be easily adjusted through the push plate 9, making it more flexible.

[0029] Reference Figure 1 and Figure 3 It also includes a data acquisition module 13 and a data processing module 14. The data acquisition module 13 includes a pressure acquisition submodule 15 and a flow acquisition submodule 16. The pressure acquisition submodule 15 is used to acquire the value of the pressure gauge 19 and feed the value back to the data processing module 14. The flow acquisition submodule 16 is used to acquire the value of the flow meter 20 and feed the value back to the data processing module 14.

[0030] Reference Figure 1 and Figure 3 The data processing module 14 includes a pressure processing submodule 17 and a flow processing submodule 18. The pressure processing submodule 17 receives the values ​​from the pressure acquisition submodule 15, decodes, analyzes, and calculates the numerical error to obtain summarized detection information, and sends the summarized detection information to the control center in real time. The flow processing submodule 18 receives the values ​​from the flow acquisition submodule 16, decodes, analyzes, and calculates the numerical error to obtain summarized detection information, and sends the summarized detection information to the control center in real time. The display module of the control center displays the measurement results based on the detection information, and the document module of the control center generates and saves the measurement results. Before inflation, the initial volume V0 = 0, and the initial air pressure P0 = 0. According to existing related technologies, during the inflation detection process... Where k is the proportionality coefficient, and k must be within 0.955*10 -3 ~2.86*10 -3 L / P a Within the range.

[0031] The implementation principle of this application embodiment is as follows: In the initial state, water fills the second container 3 and the third container 4. When the insufflator 24 is not inflated, the initial air pressure and initial volume in the container 1 are both zero. In the testing state, the insufflator 24 is started to inflate the third container 4. Some of the water in the third container 4 is squeezed out into the second container 3 by the gas. The excess liquid in the second container 3 is discharged from the second container 3 to the first container 2. At this time, there is a height difference between the liquid in the second container 3 and the third container 4. The pressure gauge 19 and the flow meter 20 record the actual values ​​at this time. The actual values ​​are processed and summarized with the set values ​​of the insufflator 24 to realize the performance test of the insufflator 24. After the performance test of the insufflator 24 is completed, the pressure relief valve is opened to release the gas in the third container 4. The water pump is started, and the water pump delivers the water in the first container 2 to the second container 3. Since the bottom of the second container 3 and the third container 4 are connected, the insufflator 24 can be tested again when the water in the second container 3 and the third container 4 are full. The automated testing of the insufflator 24 testing device enables intelligent metrological calibration of the insufflator 24, improving the accuracy of testing the performance of the insufflator 24.
