Description

Technical Field

[0001] The present invention relates to the technical field of intra-abdominal pressure monitoring, and particularly to a continuous non-invasive intra-abdominal pressure monitoring device. Background Technique

[0002] The measurement methods of intra-abdominal pressure are divided into direct measurement method and indirect measurement method. The direct measurement method refers to measuring the pressure through an abdominal drainage tube or a puncture needle connected to a sensor. The measured value is relatively accurate, but this method has certain trauma. Since the abdominal conditions of most patients are relatively complex, this method is less commonly used clinically. The indirect measurement method reflects the abdominal pressure by measuring the pressure of flatulence in the abdominal cavity. Among them, the intravesical pressure can objectively reflect the intra-abdominal pressure, and has the advantages of simple operation and less trauma, and is often used clinically. The method is that the patient lies flat. Under aseptic operation, a special urinary catheter is inserted into the bladder through the urethra. After emptying the bladder, the three-way valve is adjusted so that about 50-100 mL of sterile saline is injected into the bladder through the urinary catheter. Then the urinary catheter is clamped, and the three-way valve is adjusted again to make the urinary catheter communicate with the atmosphere. Taking the pubic symphysis as the zero point, the height of the water column measured is the intra-abdominal pressure measurement value.

[0003] In the process of measuring abdominal pressure by the indirect measurement method, there are many and cumbersome steps. Because a pressure measuring tube and an injection tube are required for injecting physiological saline, this structure needs to be realized by a three-way tube. However, in different steps, the valves of the corresponding pipelines need to be opened and the others need to be closed. For example, when simply injecting physiological saline into the abdominal cavity, only the valve of this part is opened. When measuring, the pressure measuring tube and the injection tube need to be opened simultaneously. After the test is completed, the valves of the discharge tube and the injection tube need to be opened simultaneously, and the pressure measuring tube needs to be closed. In the whole process, the switches of the valves need to be switched multiple times, and each valve is operated separately, which is prone to errors. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a continuous non-invasive intra-abdominal pressure monitoring device to solve the problems raised in the above background technology. The structure of the present invention is novel. The clamping blocks of the installation component and the three sets of clamping frames clamp the connection ends of the pressure measuring tube and the main tube. The clamping frames can open and close the two ends of the main tube and the pressure measuring tube respectively. Under the switching use of the driving component, corresponding pipelines can be selected to be opened separately or multiple pipelines can be opened or closed simultaneously according to the progress of the measurement steps, avoiding artificial switching errors in the middle, being convenient to use, and the device can be reused after replacing the main tube and the pressure measuring tube.

[0005] To achieve the above object, the present invention is realized through the following technical solutions: A continuous non-invasive intra-abdominal pressure monitoring device, including a main tube, one end of the main tube is fixed with a plug, and the other end of the main tube is connected with a urine bag. A pressure measuring tube is installed at the middle position of the main tube, and a pressure sensor is installed at the other end of the pressure measuring tube. An installation component is provided at the connection end of the main tube and the pressure measuring tube. The installation component includes two clamping blocks, which are wrapped around both sides of the connection end of the main tube and the pressure measuring tube. An injection port is provided on one side of the main tube passing through the clamping block, and a filling port is provided at the top of the pressure measuring tube. Sealing plugs are inserted at the mouths of the injection port and the filling port. Two groups of first clamping frames are provided at the position of the clamping block corresponding to the front end of the main tube, two groups of third clamping frames are provided at the position of the clamping block corresponding to the rear end of the main tube, and a second clamping frame is provided at the position of the clamping block corresponding to the bottom of the pressure measuring tube. A driving component is provided on the outer surface of the clamping block. The driving component includes a first transmission belt and a second transmission belt. The first transmission belt is connected to the first clamping frame and the third clamping frame in a transmission manner, and the second transmission belt is connected to the first clamping frame and the second clamping frame in a transmission manner. A connection component is provided at the bottom of the clamping block. The connection component includes a placement frame, and the urine bag is placed inside the placement frame.

[0006] Further, the installation component further includes a moving frame. Ear plates are fixed to the top of the first clamping frame and the side of the second clamping frame, and a moving frame is fixed to the clamping block corresponding to the position of the ear plate. The ear plates slide along the inside of the moving frame. The moving frames of the first clamping frame and the second clamping frame are on the same vertical line.

[0007] Further, a stud 0 is rotatably installed inside the moving frame through a bearing. The ear plate is threadedly sleeved on the stud 0. There is a gap between the two moving frames, and the stud 0 passes through the moving frame and is fixed with a connecting shaft. The two connecting shafts are butted together.

[0008] Further, a convex block is fixed on the surface of the connecting shaft on one side of the main tube, and a slot is opened on the surface of the connecting shaft on the other side of the main tube. The two connecting shafts are inserted through the convex block.

[0009] Further, the other end of the stud 0 at the top of the first clamping frame passes through the moving frame and is fixed with a rotating rod. Anti-loss ropes are fixed to the outer ends of the rotating rod and the outside of the second clamping frame. Spring clips are clamped on the surfaces of the sealing plugs of the injection port and the filling port. The other ends of the anti-loss ropes are fixed to the spring clips.

[0010] Further, the connection component further includes a soft belt. A soft belt is fixed to the side of the placement frame facing the clamping block, and a paste layer is provided at the bottom of the clamping block. The paste layer is pasted on the surface of the soft belt.

[0011] Further, the driving assembly further includes a rotating shaft. One side of the first clamping frame, the second clamping frame, and the third clamping frame corresponding to the first transmission belt and the second transmission belt all passes through the rotating shaft, and the rotating shaft is fixedly connected to the corresponding stud 0. The two pulleys of the first transmission belt are slidably sleeved on the rotating shafts of the first clamping frame and the third clamping frame, and the two pulleys of the second transmission belt are slidably sleeved on the rotating shafts of the first clamping frame and the second clamping block.

[0012] Further, the first transmission belt and the second transmission belt are vertically arranged, and there is a certain interval between the first transmission belt and the second transmission belt.

[0013] Further, mounting plates are installed on the back surfaces of the first transmission belt and the second transmission belt, and the mounting plates slide along the rotating shafts of the first clamping frame, the second clamping frame, and the third clamping frame respectively.

[0014] Further, convex strips are symmetrically fixed on the surfaces of the rotating shafts of the first clamping frame, the second clamping frame, and the third clamping frame, and the convex strips of the first clamping frame are located between the first transmission belt and the second transmission belt. Card slots are arranged on the inner sides of the pulleys of the first transmission belt and the second transmission belt, and the convex strips are slidably inserted into the card slots.

[0015] Advantages of the present invention:

[0016] 1. Through the clamping connection between the convex strips on the rotating shaft and the card slots of the pulleys in the present invention, it can achieve the effect of maintaining the clamping drive when the transmission belt slides horizontally along the rotating shaft. When the first transmission belt and the second transmission belt are on both sides of the convex strip of the first clamping frame, at this time, by rotating the stud 0 of the first clamping frame alone, the opening and closing of the first clamping frame can be realized alone, which can be used as the process of injecting physiological saline and will not interfere with the states of other clamping frames.

[0017] 2. By rotating the stud 0 of the second clamping frame in the present invention to realize the opening and closing of the second clamping frame, it is convenient to add physiological saline for pressure measurement into the test tube. Select a group of transmission belts to move to the convex strip. When the second transmission belt moves to the position of the convex strip, at this time, rotating the stud 0 of the first clamping frame will drive the stud 0 of the second clamping frame to rotate synchronously, and the opening of the first clamping frame and the second clamping frame can be realized simultaneously. This state can be used as the stage of measuring abdominal pressure.

[0018] 3. In the present invention, the urine bag is placed inside the placement frame and is connected to the adhesive layer of the clamping block through the soft belt. The urine bag can be selectively installed at a specified position. The soft belt limits the clamping block to keep it in a vertical state, which is convenient to add physiological saline through the vertical pressure measuring tube and perform abdominal pressure detection.

[0019] 4. In the present invention, the rotating rod and the anti-loss rope outside the second clamping frame are respectively connected to the spring clips on the surfaces of the injection port and the filling port sealing plug, thereby preventing the loss of the sealing plug. The clamping and installation of the spring clips can be connected to the sealing plug, facilitating subsequent disassembly and installation of a new measuring pipeline.

[0020] 5. Compared with the prior art, in the present invention, the clamping blocks of the installation component and the three clamping frames clamp the connection ends of the pressure measuring pipe and the main pipe. The clamping frames can open and close the two ends of the main pipe and the pressure measuring pipe respectively. Under the switching use of the driving component, corresponding pipelines can be selected to be opened individually or multiple pipelines can be opened or closed simultaneously according to the progress of the measurement steps, avoiding artificial switching errors in the middle, being convenient to use, and the device can be reused after replacing the main pipe and the pressure measuring pipe.

[0030] To make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the specific implementation manners.

[0031] Please refer to Figures 1 to 8, the present invention provides a technical solution: a continuous non-invasive intra-abdominal pressure monitoring device, including a main pipe 1. One end of the main pipe 1 is fixed with a plug 11, and the other end of the main pipe 1 is connected with a urine bag 12. A pressure measuring pipe 13 is installed at the middle position of the main pipe 1. A pressure sensor 5 is installed at the other end of the pressure measuring pipe 13. An installation component 2 is provided at the connection end of the main pipe 1 and the pressure measuring pipe 13. The installation component 2 includes two clamping blocks 21. The clamping blocks 21 are wrapped around both sides of the connection end of the main pipe 1 and the pressure measuring pipe 13. An injection port 14 is provided on one side of the main pipe 1 and penetrates through the clamping block 21. A filling port 15 is provided at the top of the pressure measuring pipe 13. Sealing plugs 16 are inserted at the pipe orifices of the injection port 14 and the filling port 15. Two groups of first clamping frames 22 are provided at the position of the clamping block 21 corresponding to the front end of the main pipe 1. Two groups of third clamping frames 26 are provided at the position of the clamping block 21 corresponding to the rear end of the main pipe 1. A second clamping frame 25 is provided at the position of the clamping block 21 corresponding to the bottom of the pressure measuring pipe 13. A driving component 4 is provided on the outer surface of the clamping block 21. The driving component 4 includes a first transmission belt 41 and a second transmission belt 45. The first transmission belt 41 is in transmission connection with the first clamping frame 22 and the third clamping frame 26, and the second transmission belt 45 is in transmission connection with the first clamping frame 22 and the second clamping frame 25. A connection component 3 is provided at the bottom of the clamping block 21. The connection component 3 includes a placement frame 31. The urine bag 12 is placed inside the placement frame 31. During the pressure measurement process, the main steps are as follows: First, connect the plug 11 to the urethral catheter. At this time, the first clamping frame 22, the second clamping frame 25, and the third clamping frame 26 are all in the clamped state. Connect a 50 ml syringe filled with 50 ml of normal saline to the injection port 14. Open the first clamping frame 22 and inject 20 ml of normal saline into the bladder of the urethral catheter. Clamp the first clamping frame 22. After 1 minute, open the second clamping frame 25 to fill it with normal saline. Align the zero scale with the horizontal position of the iliac crest connection and the mid-axillary line, that is, the bladder position. Vertically pick up the pressure measuring pipe 13. Open the first clamping frame 22 and the second clamping frame 25. The liquid level in the pressure measuring pipe 13 drops. Observe the liquid level height. After the liquid level height is stable, record the reading, which is the intra-abdominal pressure value. Measure the pressure value through the pressure sensor 5 and feedback it to the terminal device, and continuous monitoring can be carried out. When the use is completed, open the third clamping frame 26 to drain the remaining saline in the pressure measuring pipe 13 into the urine bag 12, and clamp the third clamping frame 26. Before use, install the installation component 2 at the connection of the pressure measuring pipe 13 and the main pipe 1. Clamp both ends of the main pipe 1 and the bottom of the pressure measuring pipe 13 through the first clamping frame 22, the second clamping frame 25, and the third clamping frame 26 respectively. Switch the corresponding pipes for use through different steps to measure the abdominal pressure.

[0032] In this embodiment, the installation component 2 further includes a moving frame 27. Lugs 29 are fixed to the top of the first clamping frame 22 and the side of the second clamping frame 25, and a moving frame 27 is fixed to the clamping block 21 corresponding to the position of the lug 29. The lug 29 slides along the inside of the moving frame 27. The moving frames 27 of the first clamping frame 22 and the second clamping frame 25 are on the same vertical line. A stud 210 is rotatably installed inside the moving frame 27 through a bearing. The lug 29 is threadedly sleeved on the stud 210. There is a gap between the two moving frames 27, and the stud 210 passes through the moving frame 27 and is fixed with a connecting shaft 211. The two connecting shafts 211 are butted together. A convex block 212 is fixed on the surface of the connecting shaft 211 on one side of the main pipe 1, and a slot is provided on the surface of the connecting shaft 211 on the other side of the main pipe 1. The two connecting shafts 211 are inserted through the convex block 212. The two clamping blocks 21 are installed at the connection between the main pipe 1 and the pressure measuring pipe 13 in a combined manner and are clamped and fixed through a common clamping structure to limit the main pipe 1 and the pressure measuring pipe 13. At the same time, when the first clamping frame 22, the second clamping frame 25 and the third clamping frame 26 are respectively wrapped in different positions, the connecting shafts 211 between the moving frames 27 will also be butted after the clamping blocks 21 are installed. Thus, the studs 210 in the two moving frames 27 can be rotated simultaneously to drive the clamping frames to approach each other to clamp the pipeline, preventing the flow of liquid. At the same time, it is convenient to disassemble separately and can be connected and installed with other groups of pipelines.

[0033] In this embodiment, the other end of the stud 210 at the top of the first clamping frame 22 passes through the moving frame 27 and is fixed with a rotating rod 28. Anti-loss ropes 24 are fixed to the outer ends of the rotating rod 28 and the outside of the second clamping frame 25. Spring clips 23 are clamped on the surface of the sealing plugs 16 of the injection port 14 and the filling port 15. The other ends of the anti-loss ropes 24 are fixed to the spring clips 23. The anti-loss ropes 24 on the outside of the rotating rod 28 and the second clamping frame 25 are respectively connected to the spring clips 23 on the surface of the sealing plugs 16 of the injection port 14 and the filling port 15, which can prevent the loss of the sealing plugs 16. Through the clamping installation of the spring clips 23, they can be connected to the sealing plugs 16, facilitating subsequent disassembly and installation of new measuring pipelines.

[0034] In this embodiment, the connection component 3 further includes a soft belt 32. The soft belt 32 is fixed to the side of the placement frame 31 facing the clamping block 21, and a paste layer 33 is provided at the bottom of the clamping block 21. The paste layer 33 is pasted on the surface of the soft belt 32. The urine bag 12 is placed inside the placement frame 31. By connecting the soft belt 32 to the paste layer 33 of the clamping block 21, the urine bag 12 can be selectively installed at a designated position. The soft belt 32 limits the clamping block 21 to keep it in a vertical state, facilitating the addition of normal saline through the vertically arranged pressure measuring pipe 13 and performing abdominal pressure detection.

[0035] In this embodiment, the driving assembly 4 further includes a rotating shaft 43. The first clamping frame 22, the second clamping frame 25, and the third clamping frame 26 all penetrate through the rotating shaft 43 on one side corresponding to the first transmission belt 41 and the second transmission belt 45, and the rotating shaft 43 is fixedly connected to the corresponding stud 210. The two pulleys of the first transmission belt 41 are slidably sleeved on the rotating shaft 43 of the first clamping frame 22 and the third clamping frame 26. The two pulleys of the second transmission belt 45 are slidably sleeved on the rotating shaft 43 of the first clamping frame 22 and the second clamping block 21. The first transmission belt 41 and the second transmission belt 45 are vertically arranged, and there is a certain interval between the first transmission belt 41 and the second transmission belt 45. An installation plate 42 is installed on the back of the first transmission belt 41 and the second transmission belt 45. The installation plate 42 slides along the rotating shaft 43 of the first clamping frame 22, the second clamping frame 25, and the third clamping frame 26 respectively. Convex strips 44 are symmetrically fixed on the surface of the rotating shaft 43 of the first clamping frame 22, the second clamping frame 25, and the third clamping frame 26. The convex strip 44 of the first clamping frame 22 is located between the first transmission belt 41 and the second transmission belt 45. A clamping groove 46 is arranged inside the pulleys of the first transmission belt 41 and the second transmission belt 45, and the convex strip 44 is slidably inserted into the clamping groove 46. The rotating shafts 43 of the first clamping frame 22, the second clamping frame 25, and the third clamping frame 26 are located on the same side and are connected to their respective studs 210. One pulley of both the first transmission belt 41 and the second transmission belt 45 is slidably sleeved on the rotating shaft 43 of the first clamping frame 22, and the installation plate 42 also slides along the rotating shaft 43 of the first clamping frame 22. The other ends of the first transmission belt 41, the second transmission belt 45, and the installation plate 42 are respectively installed on the rotating shafts 43 of the second clamping frame 25 and the third clamping frame 26. Through the clamping connection between the convex strip 44 on the rotating shaft 43 and the pulley clamping groove 46, when the transmission belt slides horizontally along the rotating shaft 43, the effect of clamping transmission can still be maintained. When the first transmission belt 41 and the second transmission belt 45 are on both sides of the convex strip 44 of the first clamping frame 22, at this time, by rotating the stud 210 of the first clamping frame 22 alone, the opening and closing of the first clamping frame 22 can be realized alone, which can be used as the process of injecting physiological saline and will not interfere with the states of other clamping frames. Similarly, the opening and closing of the second clamping frame 25 can also be realized by rotating the stud 210 of the second clamping frame 25, which is convenient for adding physiological saline for pressure measurement into the test tube. Select a set of transmission belts to move onto the convex strip 44. When the second transmission belt 45 moves to the position of the convex strip 44, at this time, rotating the stud 210 of the first clamping frame 22 will drive the stud 210 of the second clamping frame 25 to rotate synchronously, and the first clamping frame 22 and the second clamping frame 25 can be opened simultaneously. This state can be used as the stage of measuring abdominal pressure, and the abdominal pressure is detected through the connection between the pressure sensor 5 and the pipeline. When the first transmission belt 41 moves to the position of the convex strip 44, the first clamping frame 22 and the third clamping frame 26 can be opened simultaneously, which is convenient for draining the physiological saline in the abdominal cavity into the urine bag 12. This is the final step.

[0036] Before use, the two clamping blocks 21 are installed at the connection between the main pipe 1 and the pressure measuring pipe 13 in a combined manner, and are clamped and fixed through a common clamping structure to limit the main pipe 1 and the pressure measuring pipe 13. At the same time, when the first clamping frame 22, the second clamping frame 25 and the third clamping frame 26 are respectively wrapped at different positions, the connecting shafts 211 between the moving frames 27 will also be docked after the clamping blocks 21 are installed. Thus, the studs 210 in the two moving frames 27 can be rotated simultaneously to drive the clamping frames to approach each other and clamp the pipeline, preventing the flow of liquid. The urine bag 12 is placed inside the placement frame 31 and is connected to the adhesive layer 33 of the clamping block 21 through the soft belt 32. The urine bag 12 can be selectively installed at a specified position, and the soft belt 32 limits the clamping block 21 to keep it in a vertical state, facilitating the addition of normal saline through the vertical pressure measuring pipe 13 and performing abdominal pressure detection. The rotating shafts 43 of the first clamping frame 22, the second clamping frame 25 and the third clamping frame 26 are located on the same side and are connected to their respective studs 210. One pulley of each of the first transmission belt 41 and the second transmission belt 45 is slidably sleeved on the rotating shaft 43 of the first clamping frame 22, and the mounting plate 42 also slides along the rotating shaft 43 of the first clamping frame 22. The other ends of the first transmission belt 41, the second transmission belt 45 and the mounting plate 42 are respectively installed on the rotating shafts 43 of the second clamping frame 25 and the third clamping frame 26. Through the engagement of the protrusions 44 on the rotating shaft 43 with the pulley slots 46, it can be realized that when the transmission belt slides horizontally along the rotating shaft 43, the effect of clamping and transmission can still be maintained. When the first transmission belt 41 and the second transmission belt 45 are on both sides of the protrusion 44 of the first clamping frame 22, at this time, by rotating the stud 210 of the first clamping frame 22 alone, the opening and closing of the first clamping frame 22 can be realized alone, which can be used as the process of injecting normal saline and will not interfere with the states of other clamping frames. Similarly, the opening and closing of the second clamping frame 25 can also be realized by rotating the stud 210 of the second clamping frame 25, facilitating the addition of normal saline for pressure measurement into the test tube. Select a set of transmission belts and move them to the protrusion 44. When the second transmission belt 45 moves to the position of the protrusion 44, at this time, the rotation of the stud 210 of the first clamping frame 22 will drive the stud 210 of the second clamping frame 25 to rotate synchronously, and the first clamping frame 22 and the second clamping frame 25 can be opened simultaneously. This state can be used as the abdominal pressure measurement stage, and the abdominal pressure is detected through the connection between the pressure sensor 5 and the pipeline. When the first transmission belt 41 moves to the position of the protrusion 44, the first clamping frame 22 and the third clamping frame 26 can be opened simultaneously, facilitating the discharge of the normal saline in the abdominal cavity into the urine bag 12.

For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.

This narrative style of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
