Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an ultrasonic scanning system for upper digestive tract obstruction. Background Art

[0002] Neonatal upper gastrointestinal ultrasound examination can detect the location, degree, and cause of neonatal upper gastrointestinal obstruction, thereby guiding clinical decision-making and carrying out corresponding treatment. However, most existing examination equipment requires a nurse to hold a syringe and aspirate the gas and liquid in the stomach of the child through a gastric tube to prevent the original gas and liquid in the stomach from affecting the quality of ultrasound imaging. After aspiration, normal saline is injected into the stomach of the child to fill it. After this operation is completed, an ultrasound doctor holds an ultrasound probe and scans along the stomach and duodenum of the child, and performs multi-angle scans at the obstruction site to clarify the degree and cause of obstruction. However, the subjective experience of the ultrasound doctor has a great influence on the efficiency of ultrasound scanning and the quality of ultrasound images, and this method requires more medical staff to operate, which reduces the inspection efficiency. Therefore, it is urgently needed to provide an upper gastrointestinal obstruction ultrasound scanning system to solve the problems existing in the prior art to a certain extent.

[0014] Compared with the prior art, the upper gastrointestinal obstruction ultrasound scanning system provided by the present invention has the following advantages:

[0015] The upper gastrointestinal obstruction ultrasonic scanning system provided by the present invention includes a pumping mechanism, a driving arm mechanism and a detection arm mechanism; the pumping mechanism includes a first box body and a driving component, a liquid extraction component and a liquid injection component located in the first box body, the output end of the driving component can respectively drive the movable end of the liquid extraction component and the movable end of the liquid injection component to move, and the liquid inlet end of the liquid extraction component and the liquid outlet end of the liquid injection component are both connected to the gastric tube of the child; the detection arm mechanism includes a second box body and a probe arranged in the second box body, one end of the driving arm mechanism is connected to the first box body, and the other end is connected to the second box body, and the driving arm mechanism can drive the detection arm mechanism to move in a direction close to or away from the examination area of ​​the child.

[0016] From this analysis, it can be known that the driving assembly can realize the extraction action of the extraction assembly and the injection action of the injection assembly, so that the gas and liquid in the stomach of the child can be extracted, and after the extraction, physiological saline is injected into the stomach. Since the detection arm mechanism and the pumping mechanism are connected by the driving arm mechanism in this application, the detection arm mechanism can be moved toward or away from the examination area of ​​the child through the driving arm mechanism.

[0017] Preferably, the upper gastrointestinal obstruction ultrasound scanning system in the present application can be installed on an examination bed, and during actual installation, the first box can be combined with the bed, so that during the detection process, the first box is fixed and the movement of the detection arm mechanism is realized by the driving arm mechanism. The movement of the driving arm mechanism in the present application can be realized by using the existing mechanical arm structure, and accordingly, a controller can be set in the first box in the present application to realize automatic control of the driving arm mechanism through the controller.

[0018] It should be noted that the controller in the present application can integrate the control circuit and control logic using PCB, and realize the control of the driving arm using communication control. In addition, since the body shape of newborns is roughly the same, the moving path of the driving arm mechanism in the present application can be designed to be unique, that is, the parameters such as the extension stroke and the rotation angle can be the same in each detection, thereby simplifying the control logic and action logic, improving the detection accuracy, and reducing the difficulty of operation.

[0019] Further preferably, a detection area can be designed and depicted on the examination bed, so that medical staff can place the newborn in place with reference to the detection area.

[0020] It is understandable that since the upper gastrointestinal obstruction ultrasound scanning system provided by the present application is mainly aimed at newborns, and newborns are in a state of unconsciousness during the detection process, the current inspection process requires a nurse to suction the gastric juice and gas in the stomach of the child and then inject saline solution, and an ultrasound doctor to hold the ultrasound probe for inspection. However, in the upper gastrointestinal obstruction ultrasound scanning system provided by the present application, the processes of extracting gastric juice and gas in the stomach, injecting saline solution, moving the driving arm mechanism, and detecting the detection arm mechanism can all be automatically performed by the controller, thereby reducing manpower waste.

[0021] During the actual examination, the liquid and gas in the stomach of the child are first extracted using the liquid extraction component. When the liquid and gas cannot be extracted, the injection component is used to inject saline into the stomach. Since the gas in the stomach floats on the liquid, the liquid extraction component is used again to extract the gas in the stomach, which can improve the examination effect and accuracy to a certain extent. Finally, the driving arm mechanism is used to drive the detection arm mechanism to contact the skin outside the examination area of ​​the child, and the scanning along the stomach and duodenum begins.

[0022] During the scanning process, the probe of the driving arm mechanism is always in contact with the skin of the child and is always perpendicular to the direction of liquid flow in the stomach and duodenum to ensure that the entire area of ​​the stomach and duodenum is scanned to avoid omissions. Since the liquid appears black in the stomach, when the probe is gradually scanning from the cardia position to the back, once the imaging changes from black to no imaging, it proves that the obstruction is at this position. The driving arm mechanism drives the detection arm mechanism to rotate 360° to achieve a comprehensive scan of the position, so that the obstruction area and range can be quickly checked, greatly improving the efficiency and accuracy of the detection.

[0038] like Figure 1As shown, the present invention provides an upper gastrointestinal obstruction ultrasonic scanning system, including a pumping mechanism, a driving arm mechanism and a detection arm mechanism; the pumping mechanism includes a first box body 1 and a driving component, a liquid extraction component and a liquid injection component located in the first box body 1, the output end of the driving component can respectively drive the movable end of the liquid extraction component and the movable end of the liquid injection component to move, the liquid inlet end of the liquid extraction component and the liquid outlet end of the liquid injection component are both connected to the gastric tube of the child; the detection arm mechanism includes a second box body 5 and a probe 501 arranged in the second box body 5, one end of the driving arm mechanism is connected to the first box body 1, and the other end is connected to the second box body 5, and the driving arm mechanism can drive the detection arm mechanism to move in a direction close to or away from the examination area of ​​the child.

[0039] Compared with the prior art, the upper gastrointestinal obstruction ultrasound scanning system provided by the present invention has the following advantages:

[0040] The upper gastrointestinal obstruction ultrasonic scanning system provided by the present invention can realize the extraction action of the extraction component and the injection action of the injection component through the driving component, so as to realize the extraction of gas and liquid in the stomach of the child, and after the extraction, inject physiological saline into the stomach. Since the detection arm mechanism and the pumping mechanism are connected by the driving arm mechanism in the present application, the detection arm mechanism can be moved toward or away from the examination area of ​​the child through the driving arm mechanism.

[0041] Preferably, the upper gastrointestinal obstruction ultrasound scanning system in the present application can be installed on an examination bed, and during actual installation, the first box 1 can be combined with the bed, so that during the detection process, the first box 1 is fixed and the movement of the detection arm mechanism is realized by the driving arm mechanism. The movement of the driving arm mechanism in the present application can be realized by using the existing mechanical arm structure, and accordingly, a controller can be set in the first box 1 in the present application to realize automatic control of the driving arm mechanism.

[0042] It should be noted that the controller in the present application can integrate the control circuit and control logic using PCB, and realize the control of the driving arm using communication control. In addition, since the body shape of newborns is roughly the same, the moving path of the driving arm mechanism in the present application can be designed to be unique, that is, the parameters such as the extension stroke and the rotation angle can be the same in each detection, thereby simplifying the control logic and action logic, improving the detection accuracy, and reducing the difficulty of operation.

[0043] Further preferably, a detection area can be designed and depicted on the examination bed, so that medical staff can place the newborn in place with reference to the detection area.

[0044] It is understandable that since the upper gastrointestinal obstruction ultrasound scanning system provided by the present application is mainly aimed at newborns, and newborns are in a state of unconsciousness during the detection process, the current inspection process requires a nurse to suction the gastric juice and gas in the stomach of the child and then inject saline solution, and an ultrasound doctor to hold the ultrasound probe for inspection. However, in the upper gastrointestinal obstruction ultrasound scanning system provided by the present application, the processes of extracting gastric juice and gas in the stomach, injecting saline solution, moving the driving arm mechanism, and detecting the detection arm mechanism can all be automatically performed by the controller, thereby reducing manpower waste.

[0045] In the actual inspection process, the liquid and gas in the stomach of the child are first extracted using the liquid extraction component. When the liquid and gas cannot be extracted, the liquid injection component is used to inject saline into the stomach. Since the gas in the stomach floats on the liquid, the liquid extraction component is used again to extract the gas in the stomach, thereby improving the inspection effect and accuracy to a certain extent. Finally, the driving arm mechanism is used to drive the detection arm mechanism to contact the skin outside the inspection area of ​​the child, and start scanning along the stomach and duodenum. Therefore, the inspection area mentioned above in this application mainly refers to the area corresponding to the stomach and duodenum.

[0046] During the scanning process, the probe 501 of the driving arm mechanism is always in contact with the skin of the child and is always perpendicular to the flow direction of the stomach and duodenum liquid to ensure that the entire area of ​​the stomach and duodenum is screened to avoid omissions. Since the liquid appears black in the stomach, when the probe 501 gradually screens from the cardia position to the back, once the imaging changes from black to no imaging, it proves that the obstruction is at this position. The driving arm mechanism drives the detection arm mechanism to rotate 360° to achieve a comprehensive scan of the position, so that the obstruction area and range can be quickly checked, which greatly improves the efficiency and accuracy of the detection.

[0047] It should be noted that the probe 501 in the present application is connected to the existing scanning and imaging equipment, and the connection method and the development principle adopt the current mature technology to achieve the imaging purpose during the inspection process, which will not be repeated here.

[0048] Optionally, the driving assembly in the present application includes a first driving member and a second driving member, the output end of the first driving member is connected to the active end of the liquid extraction assembly, and the output end of the second driving member is connected to the active end of the liquid injection assembly.

[0049] Since the extraction component and the injection component need to act alternately and at intervals, in this embodiment, two independent first drive components and second drive components are used to drive the extraction component and the injection component separately, thereby avoiding mutual interference between the two and achieving the actions of pumping air, pumping liquid and injecting saline.

[0050] It should be noted that the first driving member and the second driving member in the present application can adopt telescopic structures such as oil cylinders, air cylinders or electric telescopic rods, so as to achieve the driving of the liquid pumping component and the liquid injection component.

[0051] Alternatively, if Figure 3 Combination Figure 4 As shown, the driving assembly in the present application includes a third driving member 6, a first driving rod 7, a second driving rod 8, a first threaded sleeve 701 and a second threaded sleeve 801, and a partition 9 is provided in the first box body 1; the third driving member 6 includes a first output shaft 601 and a second output shaft, the first output shaft 601 is transmission-connected to one end of the first driving rod 7, and the other end of the first driving rod 7 is rotationally connected to the partition 9; the second output shaft is transmission-connected to one end of the second driving rod 8, and the other end of the second driving rod 8 is rotationally connected to the partition 9; threads are formed on the first driving rod 7 and the second driving rod 8, the first threaded sleeve 701 is arranged on the first driving rod 7, the second threaded sleeve 801 is arranged on the second driving rod 8, the first threaded sleeve 701 is connected to the movable end of the liquid extraction assembly, and the second threaded sleeve 801 is connected to the movable end of the liquid injection assembly.

[0052] In this embodiment, the third drive component 6 in the present application is a dual-output shaft asynchronous motor, that is, it has two output shafts, and the two output shafts can control the action separately, so that distributed control action can be achieved by one motor, which greatly saves the manufacturing cost of the above two drive components.

[0053] In this embodiment, the transmission connection between the first drive rod 7 and the first output shaft 601 and the second drive rod 8 and the second output shaft can be achieved by using bevel gears. That is, since the first output shaft 601 and the second output shaft and the first drive rod 7 and the second drive rod 8 in the present application are perpendicular to each other, the bevel gears can be used to achieve the effect of reversing, thereby realizing the power transmission of the overall structure.

[0054] It can be understood that the partition 9 arranged in the first box body 1 can provide stable bearing for the first drive rod 7 and the second drive rod 8, and the rotational connection between the first drive rod 7 and the second drive rod 8 and the partition 9 can adopt bearings, that is, bearings are embedded in the corresponding positions of the partition 9, so that the first drive rod 7 and the second drive rod 8 are connected to the corresponding inner rings of the bearings, thereby achieving the purpose of rotation relative to the partition 9.

[0055] Since threads are formed on the first driving rod 7 and the second driving rod 8 in the present application, by correspondingly arranging the first threaded sleeve 701 and the second threaded sleeve 801 on the first driving rod 7 and the second driving rod 8, when the first driving rod 7 and the second driving rod 8 rotate, the first threaded sleeve 701 and the second threaded sleeve 801 can achieve the purpose of reciprocating movement along the extension direction of the rod body. Since the first threaded sleeve 701 is connected to the movable end of the liquid extraction component and the second threaded sleeve 801 is connected to the movable end of the liquid injection component, the purpose of liquid extraction, air extraction and liquid injection can be achieved through the movement of the first threaded sleeve 701 and the second threaded sleeve 801.

[0056] Alternatively, if Figure 3 Combination Figure 4 As shown, the liquid extraction assembly in the present application includes a liquid extraction tube and a first connecting tube 14; the liquid extraction tube includes a first piston rod 12 and a first tube body 10, the first piston rod 12 is arranged in the first tube body 10, and one end of the first piston rod 12 located outside the first tube body 10 is connected to the first threaded sleeve 701; one end of the first connecting tube 14 is connected to the liquid extraction end of the first tube body 10, and the other end is connected to the gastric tube.

[0057] The first piston rod 12 can realize piston movement in the first tube body 10, so as to utilize the piston movement to realize extraction of gas and liquid in the stomach.

[0058] The first connecting tube 14 can be used to connect the first tube body 10 with the gastric tube. Since the gastric tube is a pre-buried structure, during inspection, it is only necessary to connect the first connecting tube 14 with the gastric tube.

[0059] Alternatively, if Figure 3 Combination Figure 4 As shown, the injection assembly in the present application includes an injection tube and a second connecting tube 15; the injection tube includes a second piston rod 13 and a second tube body 11, the second piston rod 13 is arranged in the second tube body 11, and one end of the second piston rod 13 located outside the second tube body 11 is connected to the second threaded sleeve 801; one end of the second connecting tube 15 is connected to the injection end of the second tube body 11, and the other end is connected to the gastric tube.

[0060] The second piston rod 13 can realize piston movement in the second tube body 11 , so as to utilize the piston movement to push out the physiological saline contained in the second tube body 11 , so that the physiological saline enters the stomach.

[0061] The second connecting tube 15 can be used to connect the second tube body 11 with the stomach tube. Since the stomach tube is a pre-buried structure, during inspection, it is only necessary to connect the second connecting tube 15 with the stomach tube.

[0062] It should be supplemented here that, since the first connecting tube 14 and the second connecting tube 15 in the present application need to be connected to the stomach tube, the three tubes can be connected by using a three-way structure. Accordingly, the liquid outlet end of the first tube body 10 and the liquid inlet end of the second tube body 11 in the present application can extend out of the first box body 1 and connect with the corresponding first connecting tube 14 and second connecting tube 15, thereby reducing the difficulty of connecting the first tube body 10 and the first connecting tube 14 and the second tube body 11 and the second connecting tube 15 to a certain extent, and facilitating replacement.

[0063] It should be further explained here that the second tube body 11 in the present application takes in a corresponding volume of physiological saline and then is placed in the first box body 1 .

[0064] Alternatively, if Figure 3 Combination Figure 4 As shown, in the present application, the first threaded sleeve 701 and the second threaded sleeve 801 both include a sleeve portion 8011, a connecting rod portion 8012 and a connecting portion 8013; the sleeve portion 8011 is sleeved on the corresponding first drive rod 7 and the second drive rod 8, one end of the connecting rod portion 8012 is connected to the sleeve portion 8011, and the other end is connected to the connecting portion 8013, and the first piston rod 12 and the second piston rod 13 are connected to the connecting portion 8013 at one end located outside the first tube body 10 and the second tube body 11.

[0065] Alternatively, if Figure 3 Combination Figure 4 As shown, the connecting portion 8013 in the present application includes a first positioning plate and a second positioning plate, the first positioning plate and the second positioning plate are arranged at intervals to form a positioning space, and the first piston rod 12 and the second piston rod 13 are formed with connecting plates at one end outside the first tube body 10 and the second tube body 11, and the diameter of the connecting plate is larger than the diameter of the first piston rod 12 and the second piston rod 13; a first channel is formed on the first positioning plate, the first channel extends along the radial direction of the first positioning plate and passes through the edge of the first positioning plate, and the width of the first channel is adapted to the rod body diameter of the first piston rod 12 and the second piston rod 13.

[0066] A positioning space can be formed by the first positioning piece and the second positioning piece arranged at intervals, so as to accommodate the connecting piece formed at the ends of the first piston rod 12 and the second piston rod 13. A first channel is formed on the first positioning piece, and one end of the first channel passes through the edge of the first positioning piece in the radial direction of the first positioning piece. The width of the first channel is adapted to the rod body diameter of the first piston rod 12 and the second piston rod 13. Therefore, the first piston rod 12 and the second piston rod 13 can enter through the first channel, thereby driving the connecting piece to finally enter the positioning space, and then the first piston rod 12 and the second piston rod 13 can be driven to reciprocate through the connecting portion 8013 composed of the first positioning piece and the second positioning piece.

[0067] Alternatively, if Figure 1-Figure 3 As shown, a second channel 901 is formed on the partition 9 in the present application, and the second channel 901 includes a first section 9011 and a second section 9012 that are connected to each other, and the end of the first section 9011 away from the second section 9012 passes through the edge of the partition 9; the width of the first section 9011 is adapted to the diameter of the second tube body 11, and the width of the second section 9012 is adapted to the diameter of the first piston rod 12; a first limiting piece 1001 is formed at the end of the first tube body 10 away from the liquid extraction end, and the diameter of the first limiting piece 1001 is greater than the width of the second section 9012; a second limiting piece 1101 is formed at the end of the second tube body 11 away from the liquid injection end, and the diameter of the second limiting piece 1101 is greater than the width of the first section 9011; the first box body 1 includes a main body 101 and a cover portion 102, one side of the main body 101 forms an opening, and the cover portion 102 is detachably connected to the main body 101, and the opening can be opened or closed.

[0068] The second channel 901 formed on the partition 9 can provide an installation basis for the first tube body 10 and the second tube body 11 to ensure the stability of the first tube body 10 and the second tube body 11. It can be understood that in the present application, multiple brackets can also be set in the first box body 1 to support the first tube body 10 and the second tube body 11.

[0069] Since the first piston rod 12 needs to perform a pulling action, during assembly, the first piston rod 12 is first sent into the first section 9011 of the second channel 901, and then enters the second section 9012, and the first limiting plate 1001 is made to abut against the side of the partition 9 away from the connecting portion 8013. Since the diameter of the first limiting plate 1001 is greater than the width of the second section 9012, the first tube body 10 can be limited when the first piston rod 12 is pulled.

[0070] Correspondingly, since the second piston rod 13 in the present application needs to perform a pushing action, the second limiting plate 1101 is abutted against the side of the partition 9 toward the connecting portion 8013. When the second piston rod 13 is pushed, the second limiting plate 1101 can be used to limit the second tube body 11 to ensure the injection of physiological saline.

[0071] It can be understood that since the liquid extraction component and the liquid injection component in the present application are both disposable items, the first box body 1 can be opened or closed by making the first box body 1 include a main body 101 and a cover part 102 detachably connected to the main body 101, and the cover part 102 in the present application is located at one end of the edge of the second channel 901 that passes through the partition 9, so that the liquid extraction component and the liquid injection component can be taken out from the second channel 901 after the cover part 102 is removed.

[0072] Accordingly, new liquid extraction components and liquid injection components are sequentially placed through the second channel 901 to avoid infection caused by repeated use of supplies.

[0073] Preferably, the sealing cover 102 in the present application may be made of a transparent material, so that observation can be performed during the process of pumping liquid and air as well as injecting liquid, thereby ensuring the safety of the inspection process.

[0074] Since the second tube 11 is in a state of containing physiological saline, the second piston rod 13 is in a stretched position, so that the second threaded sleeve 801 located on the second driving rod 8 in the present application is in a suitable position to achieve the purpose of inserting the connecting piece into the positioning space. The above-mentioned suitable position can be the extreme position where the second threaded sleeve 801 can move on the second driving rod 8, so as to ensure assembly accuracy and speed.

[0075] Alternatively, if Figure 1 Combination Figure 2 As shown, the detection arm mechanism in the present application also includes a pressure sensor 502, a coupling agent output component 503 and a telescopic component 4; the pressure sensor 502 is located on the side of the second box 5 facing the skin of the child, the coupling agent output component 503 is arranged in the second box 5, and the outlet of the coupling agent output component 503 is located at the front end of the probe 501 on the travel route of the second box 5; the positioning end of the telescopic component 4 is rotatably connected to the end of the driving arm mechanism away from the first box 1, and the telescopic end of the telescopic component 4 is connected to the second box 5.

[0076] The pressure sensor 502 can detect the degree of fit and pressure between the second box 5 and the skin of the child, so that the telescopic degree of the telescopic component 4 can be adjusted by the controller, thereby adjusting the pressure and ensuring the accuracy of the inspection. The telescopic component 4 in the present application can be a cylinder, and the telescopic cylinder can be used to achieve the purpose of moving the second box 5 closer to or away from the second arm 3, thereby achieving the pressure applied by the second box 5 to the child, thereby ensuring the clarity and accuracy of the inspection.

[0077] During the examination, coupling agent needs to be applied to the child's skin to increase lubrication and eliminate air between the probe 501 and the skin to ensure the clarity and accuracy of the examination. Therefore, the present application further provides a coupling agent output component 503 in the second box 5 to release the coupling agent during the examination.

[0078] The coupling agent output component 503 in the present application can adopt an automatic liquid dispenser, that is, when the pressure sensor 502 detects contact with the child's skin, and the second box 5 starts to move, and the probe 501 starts to check, the automatic liquid dispenser starts to output the coupling agent. Since the coupling agent output component 503 in the present application is located in front of the probe 501 in the moving direction of the second box 5, the positions detected by the probe 501 will be coated with coupling agent by the coupling agent output component 503 to ensure the detection accuracy.

[0079] Alternatively, if Figure 1 Combination Figure 2 As shown, the driving arm mechanism in the present application includes a first arm body 2, a first rotating member 201, a second arm body 3 and a second rotating member 301; one end of the first rotating member 201 is rotatably connected to the first box body 1, and the other end is connected to one end of the first arm body 2, one end of the second rotating member 301 is rotatably connected to the other end of the first arm body 2, the other end of the second rotating member 301 is connected to the second arm body 3, and the end of the telescopic assembly 4 away from the second box body 5 is rotatably connected to the second arm body 3.

[0080] The first rotating member 201 and the second rotating member 301 in the present application both include a driving member and a rotating rod, and the driving member can use a motor to drive the gear to rotate, and a gear ring is set on the rotating rod, so that the rotation of the rotating rod is realized through the cooperation of the gear and the gear ring, thereby realizing the rotation of the first arm body 2 and the second arm body 3.

[0081] Since the driving member still adopts a motor, it can also be controlled by the above-mentioned controller, so as to realize the automatic operation of the overall scanning system provided by the present application.

[0082] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
