Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically to a bladder pressure and abdominal pressure measuring device. Background Technology

[0002] Critically ill patients with conditions such as intestinal obstruction, sepsis, and pancreatitis often have indwelling urinary catheters for regular abdominal pressure monitoring. Since the bladder is an intra-abdominal structure, changes in bladder pressure reflect changes in intra-abdominal pressure. Therefore, bladder pressure is highly correlated with indirectly measured intra-abdominal pressure and is considered the "gold standard" for indirect intra-abdominal pressure measurement in clinical practice. Monitoring bladder pressure is crucial for treating critically ill patients. However, due to the presence of indwelling catheters, it is also necessary to simultaneously perform on-demand or pressure-controlled urination; otherwise, it may cause harm to the patient. This is especially true for critically ill patients such as those in a coma or with cerebral hemorrhage who require indwelling catheters and need real-time bladder pressure monitoring and urination based on clinical needs. Currently, there is no non-disposable product that can simultaneously perform pressure monitoring and automatic urination.

[0003] In addition, existing constant pressure self-releasing drainage systems do not have bladder pressure monitoring functions, nor can they measure the actual pressure and capacity of the bladder, and cannot detect and evaluate bladder function. As a result, effective treatment methods cannot be adopted for the condition. At the same time, traditional drainage systems do not have the function of monitoring abdominal pressure.

[0004] Therefore, measuring bladder pressure and monitoring bladder pressure in real time, understanding bladder function and intra-abdominal pressure, and helping the bladder to urinate properly by monitoring real-time bladder pressure are urgent problems that need to be solved. Summary of the Invention

Detailed Implementation

[0019] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments are not limited to the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0020] In the description of the plan, the direction closer to the operator is the near end, and the direction farther away from the operator is the far end.

[0021] like Figure 1 As shown, a bladder pressure and abdominal pressure measuring device includes a vertical pressure display tube 3 at the rear of a catheter 2 connected to a drainage tube or urinary catheter, which displays bladder pressure, and an automatic urine discharge line 9 extending downward from the top of the pressure display tube 3; a fluid guide tube connector 1 or a connector with a vent hole on the fluid guide tube is connected to the front of the pressure display tube 3; and the automatic urine discharge line 9 is connected to a waste fluid collection bag. In practical use, the connector at the tip of catheter 2 connects to a urinary catheter. Catheter 2 can also be a continuation of the urinary catheter. Bladder pressure or abdominal pressure is obtained by observing the height of the liquid column in the vertical pressure display tube 3, either from urine or the fluid injected into the bladder. When the bladder is saturated or the corresponding pressure exceeds the top of the pressure display tube 3, urine is automatically discharged into a waste collection bag with a vent or membrane via the downward-facing automatic urine discharge tube 9. The automatic discharge pressure can be adjusted by moving the top and turning part of the pressure display tube 3. The waste collection bag has a vent or membrane and is positioned below the bladder. After discharge, the presence of a vent allows for continued discharge from the pressure display tube 3 and the automatic urine discharge tube 9, facilitating subsequent observation of bladder pressure. The vent should be designed to not affect the continuity of the discharge flow after the start of the discharge.

[0022] It also includes a height measuring device for measuring the height of the liquid column in the pressure display tube 3. This height measuring device can be suspended or placed on the ground or fixed to the side of the bed. The apex of the pressure display tube 3 can be adjusted or moved within the height measuring area of ​​the height measuring device. The height measuring device can be suspended or fixed to an infusion hook or infusion stand, or it can be placed on the ground or beside the bed using a dedicated fixing device. The height of the height measuring device from the ground is adjustable. The apex of the pressure display tube 3, with its limiting and fixed position, is fixed to the height measuring device and can be adjusted or moved up and down within the measuring area, thus allowing the setting of a trigger pressure for automatic urine discharge.

[0023] The height measuring device includes a scale plate 4 and a catheter direction conversion and height adjustment device 5. The scale plate 4 can be suspended from the infusion stand via a rope on the scale plate suspension and fixing device 6, and its height can be adjusted by the rope. Alternatively, the scale plate 4 can be placed on a floor-mounted, height-adjustable scale plate suspension and fixing device bracket 12. The scale plate 4 has graduations or corresponding pressure values, and its zero position can be adjusted to meet clinical requirements by adjusting the fixed height of the height measuring device. The catheter direction conversion and height adjustment device 5 uses a diverting tube or catheter diverter to redirect the pressure display tube 3 to the downward-facing automatic urine discharge tubing 9.

[0024] The conduit direction conversion and height adjustment device 5 can be a reverse fluid circuit device that can connect to the conduit.

[0025] Of course, the conduit direction conversion and height adjustment device 5 can also be a conduit turning device, that is, it has a turning conduit groove to accommodate the conduit, such as a semi-circular conduit groove with the opening facing downward. After a conduit is placed in the semi-circular conduit groove, it naturally achieves a 180-degree turn.

[0026] The conduit direction conversion and height adjustment device 5 is movably fixed in the guide groove 7 on the scale plate 4, or it can be a sliding block or other sliding mechanism. The position of the conduit direction conversion and height adjustment device 5 can be adjusted by moving it up and down along the guide groove 7.

[0027] The conduit direction conversion and height adjustment device 5 can also be attached to the liquid column scale plate 4 by a magnet for easy height movement or adjustment.

[0028] The ruler plate 4 is made of plastic, metal, or other materials. The catheter direction conversion and height adjustment device 5 is an injection molded, vacuum-formed, or metal part, with an "n"-shaped catheter groove on its back to accommodate the upper part of the pressure display tube 3 and the downward turning catheter. During assembly, the upper catheter of the display tube 3 is directly placed into the "n"-shaped catheter groove to form the turning part and the downward automatic urine discharge pipeline. If the catheter direction conversion and height adjustment device 5 has a reverse liquid passage inside, it is only necessary to connect the upper end of the pressure display tube 3 to the front end of the automatic urine discharge pipeline. The catheter direction conversion and height adjustment device 5 is equipped with a one-way buckle to slide and fix it on the ruler plate 4. The ruler plate 4 can also be equipped with a catheter fixing buckle 8 for easy catheter fixation.

[0029] A connecting tube 11 can also be placed between the front and rear catheters of the pressure display tube 3. This device facilitates manual drainage of fluid from the bladder. If the connecting tube 11 is not provided, the catheter 2 connecting the drainage tube or urinary catheter, the bladder pressure display tube 3, and the automatic urine discharge tube 9 can be a continuous tube of the same material and diameter. This configuration is simple in structure and easy to manufacture.

[0030] The product can also be configured with two-way, three-way, or multi-way drainage tubes or urinary catheters 13. The multiple access channels are mainly for the convenience of pushing or infusing fluid into the bladder through these channels to test bladder function. For convenience, a syringe or infusion set-like bladder fluid infusion device 14 is also configured. In addition, the waste fluid collection bag is a precision metering waste fluid collection bag 10, which can measure bladder capacity and calculate safe bladder capacity in combination with bladder pressure display.

[0031] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. 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.

[0032] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. All equivalent embodiments or modifications made without departing from the spirit of the present invention should be included within the scope of protection of the present invention.
