Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer, more thorough understanding of the present application and to convey the complete scope of the present application to those skilled in the art.

[0042] Embodiment 1:

[0043] As shown in Figure 1 and Figure 2 According to the embodiment of the present application, an intra-abdominal pressure measuring device is provided, comprising: a urinary catheter body 100; an intra-abdominal pressure measuring device 200, comprising a measuring tube 210 and a connecting end 220 arranged on the measuring tube 200, the connecting end 220 being in communication with the urinary catheter body 100; a support assembly 300, the intra-abdominal pressure measuring device 200 being mounted on the support assembly 300, the support assembly 300 being used to adjust the relative position of the intra-abdominal pressure measuring device 200 relative to the patient.

[0044] The intra-abdominal pressure measuring device provided by the embodiment of the present application comprises a urinary catheter body 100, an intra-abdominal pressure measuring device 200 and a support assembly 300, wherein the intra-abdominal pressure measuring device 200 comprises a measuring tube 210 and a connecting end 220, the urinary catheter body 100 is connected with the connecting end 220, and the connecting end 220 is located on the measuring tube 210, which is designed to achieve close and reliable communication with the urinary catheter body 100. The material of the connecting end has good sealing property and durability, and can withstand multiple connections and disconnections without damage. When connecting, medical staff need to ensure that the connecting end is firmly connected with the urinary catheter body to ensure the accuracy of the measurement.

[0045] The intra-abdominal pressure measuring device 200 is installed on the support assembly 300 to ensure the stability of the entire device during the measurement process. The support assembly 300 has high adjustability, which can finely adjust the position of the intra-abdominal pressure measuring device 200 relative to the patient. Specifically, the support assembly 300 can be adjusted in multiple dimensions. In the vertical direction, the height of the intra-abdominal pressure measuring device 200 can be adjusted up and down according to the height of the patient, the height of the bed, and the specific needs of the measurement, so that the measuring tube 210 and the connecting end 220 are in the most suitable position to better communicate with the urinary catheter body 100 and perform accurate pressure measurement. In the horizontal direction, the support assembly 300 can move the intra-abdominal pressure measuring device 200 left and right to adapt to different bed layouts and patient positions. In addition, the support assembly 300 can also be adjusted in angle, so that the measuring tube 210 can be aligned with the patient at the most appropriate angle to avoid affecting the measurement results due to improper angle. In actual use, the adjustment function of the support assembly 300 provides great convenience for medical personnel. It can be personalized according to the specific circumstances of different patients to ensure that the intra-abdominal pressure measuring device 200 is always in the best measurement position, thereby improving the accuracy and reliability of the measurement. Whether for patients of different sizes or in different medical environments, the support assembly 300 can demonstrate its unique advantages and provide strong support for intra-abdominal pressure measurement.

[0046] As shown in Figure 1 and Figure 2 , in some examples, the above-mentioned support assembly 300 includes a support crossbar 310, which is formed with a clamping space 301, and the measuring tube 210 is installed in the clamping space 301; a lifting member 320 is hinged to at least one end of the support crossbar 310; and a base 330 is provided at the bottom of the lifting member 320.

[0047] In this technical solution, the support assembly 300 includes a support crossbar 310, a lifting member 320, and a base 330. The support crossbar 310 is formed with a clamping space 301, the size and shape of which can be set according to the measuring tube 210 to perfectly fit the measuring tube 210. The inner wall of the clamping space 301 is wrapped with soft material, which can also avoid scratching or damaging the measuring tube 210. When installing the measuring tube 210, medical personnel can easily put the measuring tube into the clamping space 301. The design of the clamping space 301 makes the installation and removal of the measuring tube very convenient and efficient, improving work efficiency.

[0048] The lifting member 320 bears the function of adjusting the height in the support assembly 300. It is hinged to at least one end of the support crossbar 310, so that the support crossbar 310 can be flexibly adjusted in the vertical direction.

[0049] Exemplarily, the lifting member 320 is made of high-strength metal material, has good stability and load-bearing capacity, and can realize stable lifting of the support crossbar 310 through rotation of the adjustment knob or pulling of the pull rod, etc. During lifting, the lifting member can maintain stable supporting force and will not shake or jam.

[0050] The hinged design of the lifting member 320 enables the support crossbar to be adjusted in a certain angle range, further increasing the flexibility of the measuring device. Medical staff can easily adjust the height and angle of the support crossbar according to the patient's body position, the height of the hospital bed, and the actual measurement needs, to ensure that the measuring tube can accurately communicate with the catheter body and obtain the best measurement effect.

[0051] The base 330 is the basic part of the support assembly 300, providing stable support for the entire device. Exemplarily, the base 330 can be made of heavy metal material, but is not limited thereto, and has a large bottom area to increase the contact area with the ground and improve the stability of the device. Exemplarily, the design of the base 330 takes into account various use scenarios, and the bottom is usually equipped with anti-slip rubber pads, which can effectively prevent the base from sliding on a smooth floor. Even in a busy hospital environment, it can ensure that the measuring device will not affect the measurement results due to accidental collisions or movements during use.

[0052] The base 330 and the lifting member 320 are firmly connected together to form a stable whole. During installation and use, the base can be fixed to the ground or beside the hospital bed through bolts to further improve the stability of the device. At the same time, the design of the base also facilitates movement and transportation, and when the measuring device needs to be used between different wards or departments, it can be easily pushed to the desired location.

[0053] In summary, the various parts of the support assembly 300 cooperate with each other to provide reliable support and flexible adjustment function for the intra-abdominal pressure measuring device. The lifting member 320 realizes the adjustment of height and angle, and the base 330 provides a stable foundation for the entire device.

[0054] As shown in Figure 1 and Figure 2 In some examples, the above support assembly 300 further comprises a rotating ring 340 rotatably installed in the clamping space 301, and the measuring tube 210 is clamped in the rotating ring 340.

[0055] In this technical solution, the support assembly 300 further comprises a rotating ring 340 rotatably installed in the clamping space 301, exemplarily as Figure 1As shown, the rotating ring 340 rotates left and right, providing greater flexibility for the installation and adjustment of the measuring tube 210. For example, the rotating ring 340 can be made of, but is not limited to, high-quality engineering plastics or metal materials, possessing good wear resistance and corrosion resistance. Its outer surface is finely machined to ensure a smooth rotational connection with the inner wall of the clamping space 301. The rotating ring 340 is rotatably mounted within the clamping space 301, achieving smooth rotation through bearings or other rotating mechanisms. This design allows the measuring tube 210 to be adjusted at multiple angles as needed after installation within the rotating ring. For example, medical personnel can easily rotate the measuring tube to more accurately align it with the connection end of the catheter body, or adjust the angle of the measuring tube to adapt to different measurement environments and patient positions. The measuring tube 210 is snapped into the rotating ring 340, a snap-fit ​​method that ensures both secure installation of the measuring tube 210 and facilitates quick disassembly and replacement. The inner wall of the rotating ring is usually equipped with elastic claws or grooves. When the measuring tube 210 is inserted into the rotating ring 340, the claws or grooves will firmly hold the measuring tube in place, preventing it from accidentally falling off during use. At the same time, the snap-fit ​​design also makes the installation and removal of the measuring tube 210 very simple and quick, allowing medical staff to easily complete the operation without the use of tools.

[0056] To further improve the connection stability between the measuring tube 210 and the rotating ring 340, an anti-slip pad or rubber ring can be provided on the inner wall of the rotating ring 340. These anti-slip measures can increase the friction between the measuring tube 210 and the rotating ring 340, preventing the measuring tube 210 from slipping or loosening during rotation.

[0057] In practical use, the presence of the rotating ring 340 greatly improves the ease of operation and measurement accuracy of the intra-abdominal pressure measuring device. Medical staff can flexibly adjust the angle and position of the measuring tube 210 according to specific circumstances to ensure the reliability of the measurement results.

[0058] like Figure 1 and Figure 2 As shown, in some examples, the lifting component 320 includes: a support tube 321, one end of which is fixedly mounted on the base 330; a lifting adjustment rod 322, which is coaxially slidably mounted inside the support tube 321, and the support crossbar 310 is rotatably mounted on the end of the lifting adjustment rod 322 away from the base 330; and a locking screw 323, which is threaded through and mounted on the side wall of the support tube 321. When the locking screw 323 is in close contact with the lifting adjustment rod 322, the support tube 321 and the lifting adjustment rod 322 are fixed to each other.

[0059] In this technical solution, the lifting component 320 includes a support tube 321, a lifting adjustment rod 322, and a locking screw 323. One end of the support tube 321 is firmly fixed to the base 330, ensuring that the entire lifting component 320 will not shake or tilt during use. For example, the inner wall of the support tube 321 is smooth, providing good guidance for the sliding of the lifting adjustment rod 322. The length of the support tube 321 is determined according to actual usage requirements, meeting the requirements of different height adjustment ranges.

[0060] The lifting adjustment rod 322 is the core component for achieving height adjustment. It works in conjunction with the support tube 321 and can slide coaxially within the support tube 321. The outer diameter of the lifting adjustment rod 322 is slightly smaller than the inner diameter of the support tube 321 to ensure smooth sliding.

[0061] The locking screw 323 is threaded through and installed on the side wall of the support tube 321. When it is necessary to fix the position of the lifting adjustment rod 322, the locking screw 323 is rotated to make it tightly contact the lifting adjustment rod 322. The locking screw 323 is usually made of high-strength metal material, which can provide sufficient clamping force to ensure that the support tube 321 and the lifting adjustment rod 322 are fixed to each other. In the locked state, even if a certain external force is applied, the lifting adjustment rod 322 will not slip, ensuring the stability of the measuring device.

[0062] To improve locking reliability, the head of the locking screw 323 can be designed in an easy-to-operate shape, such as hexagonal or butterfly-shaped. Additionally, an anti-slip pad or rubber pad can be provided at the contact point between the locking screw 323 and the lifting adjustment rod 322 to increase friction and prevent loosening.

[0063] In practical use, medical staff can easily adjust the height of the lifting adjustment rod 322 according to the patient's position and measurement needs, and then fix it in the desired position by rotating the locking screw 323. This height adjustment method is simple, quick, and has high precision and stability, providing a strong guarantee for the accurate measurement of intra-abdominal pressure measurement devices.

[0064] like Figure 1 As shown, in some examples, a counterweight 400 is also included, which is detachably mounted on the bottom of the measuring tube 210.

[0065] like Figure 1 As shown, in some examples, a positioning spotlight 500 is also included, which is detachably mounted on the bottom of the measuring tube 210.

[0066] The technical solution also includes a positioning spotlight 500 that can be detachably installed at the bottom of the measuring tube 210. The positioning spotlight 500 can be, but is not limited to, an infrared component. During operation, it can illuminate the mid-axillary line, thereby achieving accurate positioning.

[0067] As Figure 1 shown, in some examples, the measuring tube 210 is formed with a scale 600.

[0068] In this technical solution, the scale 600 on the measuring tube 210 is colored green, yellow, red and dark red at the positions of 10, 20, 30 and 40 respectively, so that it can be observed more quickly and intuitively whether the pressure reaches a critical value.
