[0045] In this embodiment, the base 2 is connected to the bottom of the box 1 and includes a lifting component 23. The lifting component 23 is used to adjust the height of the box 1. By setting the lifting component 23, the height of the box 1 can be easily adjusted by lifting the lifting component, thereby stably adjusting the height of the pressure measuring tube 4 set on the box 1, ensuring that the zero point height of the pressure measuring tube 4 is flush with the patient's mid-axillary line, making the measurement results more stable and the measurement accuracy better.
[0046] As an optional implementation method, Figure 2 yes Figure 1 A schematic diagram of the internal structure, such as Figure 2 As shown, the first pipeline 7 is also installed inside the box 1.
[0047] The first conduit 7 has a connector 71 at one end for connecting to the third interface 121; a puncture needle 72 at the other end of the first conduit 7, with a needle cap 73 covering the outside of the puncture needle 72; and a switch 74 and an exhaust valve 75 on the first conduit 7.
[0048] like Figure 2 As shown, the box 1 is also equipped with a pressure measuring tube 4, a urine bag 6, and a urinary catheter 3. When the patient needs to measure abdominal pressure, the first tube 7, pressure measuring tube 4, urine bag 6, and urinary catheter 3 can be taken out from the box 1 and connected to the corresponding interfaces for use.
[0049] Optionally, corresponding receiving positions are provided inside the housing 1 to receive the first pipeline 7, pressure measuring tube 4, urine bag 6 and catheter 3 respectively, so as to facilitate use and operation.
[0050] In actual use, the saline bag 5 can be placed inside the box 1 or used separately.
[0051] In this embodiment, the pressure measuring tube 4 is provided with a scale so that the intra-abdominal pressure can be reflected by the liquid height in the vertical pressure measuring tube 4 during measurement.
[0052] As an optional implementation method, Figure 3 This is a schematic diagram of the door panel after it is opened in this embodiment, as shown below. Figure 3 As shown, the front of the box 1 is provided with a transparent door panel 13.

[0060] Optionally, in this embodiment, a handle receiving groove 15 is provided on the top of the housing 1, and the handle 14 is hinged in the handle receiving groove 15. When measuring intra-abdominal pressure or when it is not necessary to lift the housing 1, the handle 14 is placed in the handle receiving groove 15, that is, the handle 14 is flush with the surface of the housing 1, avoiding interference with the measurement. When it is necessary to move the housing 1, the handle 14 is pulled up until it is perpendicular to the surface of the housing 1, and the housing 1 can be lifted by the handle 14. This design makes the overall structure of this intra-abdominal pressure measuring device neater and more practical.
[0061] As an optional implementation method, Figure 5 This is a schematic diagram of the structure used in this embodiment, as shown below. Figure 5 As shown, the base 2 includes a first base 21 and a second base 22.
[0062] The first base 21 and the second base 22 have the same structure. In this embodiment, both the first base 21 and the second base 22 adopt a plate structure, and the thickness of the plate structure is no more than 5cm. The lifting component is disposed between the first base 21 and the second base 22.
[0063] Specifically, in this embodiment, the first base 21 is fixedly connected to the bottom of the housing 1; the bottom of the second base 22 is provided with a movable component 24.
[0064] In this embodiment, the movable component 24 adopts a caster wheel structure. By setting casters at the bottom of the second base 22, the position of this intra-abdominal pressure measuring device can be moved as needed during use.
[0065] As an optional implementation, the lifting assembly 23 includes an X-shaped lifting mechanism and a hydraulic cylinder connected to the X-shaped lifting mechanism.
[0066] The upper and lower sides of the X-shaped lifting mechanism are connected to the bottom of the first base 21 and the top of the second base 22, respectively. The hydraulic cylinder is installed inside the second base 22 and drives the lifting mechanism to rise and fall stably through the hydraulic cylinder.
[0067] The usage method of this embodiment includes the following steps:
[0068] The box 1 is placed on the side of the patient using the handle 14, and the lifting component 23 is adjusted to place the box 1 at a height suitable for medical staff to operate.
[0069] Open the door panel 13 of the box 1, take out the first pipe 7, pressure measuring pipe 4, urine bag 6 and urine catheter 3 from the box 1, and connect them to the corresponding interfaces set on the surface of the box 1. Connect the urine bag 6 to the fourth interface 122 and close the door panel 13.
[0070] Connect the saline bag 5 to the first pipeline 7 and hang the saline bag on the hook 91 of the lifting rod 9. Adjust the height of the lifting rod 9 so that the saline bag 5 is placed in a suitable position.
[0071] By adjusting the first adjustment knob 110, the urine bag 6 and the catheter 3 are connected, and the other passages are closed, allowing for alternating urination. If a urine test or urine culture is required at this time, the door panel 13 can be opened, and the patient's urine can be discharged through the drain tube 61 by opening the valve 62 at the bottom of the urine bag 6.
[0072] By adjusting the first adjustment knob 110 and the second adjustment knob 120, the saline bag 5 is connected to the catheter 3, and the other passages are closed, so that saline is injected into the bladder of the patient.
[0073] Adjust the lifting assembly 23 until the zero point height of the pressure measuring tube 4 is level with the patient's mid-axillary line. By adjusting the first adjustment knob 110 and the second adjustment knob 120, the urinary catheter 3 is connected to the pressure measuring tube 4. Due to the influence of intra-abdominal pressure, physiological saline is injected into the pressure measuring tube 4 along the urinary catheter 3. At this time, the liquid level in the pressure measuring tube 4 is a reflection of the intra-abdominal pressure.
[0074] After the measurement is completed, the urine bag 6 and the catheter 3 are disposed of. The pressure measuring tube 4 and the first tubing 7 can be reused after cleaning and disinfection.
[0075] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
