Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically an intra-abdominal pressure testing kit. Background Technology

[0002] Intra-abdominal pressure, or intra-abdominal pressure, is the pressure within the closed space of the abdominal cavity in a stable state, primarily generated by the hydrostatic pressure of the abdominal organs. A pressure sensor detects fluid pressure and converts it into a usable output signal. Electronic measurement involves connecting a pressure bag, irrigation fluid, and a pressure sensor to a suitable catheter, converting the pressure signal into an electrical signal that is displayed as an intra-abdominal pressure waveform and value on a monitor.

[0003] Bladder pressure is a commonly used clinical method for measuring intra-abdominal pressure. Clinically, electronic bladder pressure measurement is frequently used, employing pressure measurement kits that are highly repeatable and accurate. However, currently, there is no single pressure measurement kit suitable for measuring intra-abdominal pressure. Nurses typically assemble their own kits using arterial blood pressure measurement kits, three-way valves, disposable syringes or homemade sterile rubber tubing, and the front end of a disposable drainage bag (for connecting a urinary catheter). These are then connected to a three-lumen or double-lumen balloon catheter. A pressure bag, irrigation fluid, and pressure sensor are used to connect to a suitable catheter, converting the pressure signal into an electrical signal that is displayed as an intra-abdominal pressure waveform and value on a monitor. This manual assembly is time-consuming, labor-intensive, and increases workload. Furthermore, the connections between components and tubing are often not secure and are prone to detachment during use. Summary of the Invention

[0004] The present invention aims to address the shortcomings of the prior art by providing an intra-abdominal pressure testing kit, which solves the problems of time-consuming and laborious manual assembly by medical personnel and the insecure connection of pipes and components after assembly.

A limiting plate is slidably connected inside the limiting groove. The limiting plate is connected to the ejection block. A limiting spring is connected between the limiting plate and the limiting groove.

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] This application provides an intra-abdominal pressure testing kit, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0029] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0030] Example 1

[0031] Please see Figure 1-7 In this embodiment, an intraperitoneal pressure testing kit is provided, comprising: a saline bag 1, a first catheter 101 connected to the top of the saline bag 1, a three-way tube 102 connected to one end of the first catheter 101, a second catheter 104 connected to the bottom of the three-way tube 102, a sensor wire 103 connected to the other end of the three-way tube 102, a sensor connector 1031 connected to one end of the sensor wire 103, and an adjusting tube 2 at the bottom of the second catheter 104; a connecting assembly provided on the adjusting tube 2 to prevent the adjusting tube 2 from falling off when connected to other tubes, the connecting assembly including: a threaded block 202, a threaded cap 3, a connecting tube 5, an interface 501, and an annular block 506; and a metering assembly provided on the adjusting tube 2 for controlling the injected saline volume, the metering assembly including: a flow channel 201, a ball channel 2011, a syringe 4, and a three-way ball valve 8.

[0032] The saline bag 1 is connected to the regulating tube 2 through the first catheter 101, the three-way tube 102 and the second catheter 104, and then connected to the intra-abdominal pressure dynamic detection instrument through the sensor wire 103 and the sensor connector 1031.

[0033] The design incorporates a modular assembly that eliminates the need for manual assembly during clinical use, improving efficiency and quality. It also ensures a secure connection between the regulating tube 2 and the second catheter 104 and the third catheter 6, preventing dislodgement due to loose connections. Furthermore, it allows for the rapid and independent separation and connection of the urinary catheter 701 and the urinary bag 7. Additionally, the quantitative component enables precise control of the amount of saline solution injected into the abdominal cavity.

[0034] Example 2

[0035] Based on embodiment 1, both ends of the regulating pipe 2 are connected to threaded blocks 202, and the threaded blocks 202 are arranged in a ring structure. The outer side of the threaded block 202 is threadedly connected to a threaded cap 3. One end of the second conduit 104 extends into the threaded block 202. The bottom of the regulating pipe 2 is connected to a third conduit 6. Multiple ejection grooves 203 are opened on the inner wall of the threaded block 202. An ejection block 204 passes through the ejection groove 203. One end of the ejection block 204 is spherical. A limiting groove communicating with the ejection groove 203 is opened inside the threaded block 202. A limiting plate 205 is slidably connected inside the limiting groove. The limiting plate 205 is connected to the ejection block 204. A limiting spring 206 is connected between the limiting plate 205 and the limiting groove.

[0036] In use, the second conduit 104 and the third conduit 6 are respectively passed through the threaded cap 3 and inserted into the threaded block 202. Then, the threaded cap 3 is rotated so that the threaded cap 3 is threaded onto the outside of the threaded block 202. During the threading process, since one end of the ejector block 204 has an inclined surface, the bottom of the threaded cap 3 contacts the inclined surface of the ejector block 204 and squeezes the ejector block 204, causing the ejector block 204 to move into the threaded block 202. This fixes the second conduit 104 or the third conduit 6 inside the threaded block 202, improves the stability between the pipes, and prevents the pipes from being pulled during use, which could cause the pipes to fall off.

[0037] By setting the limiting groove and the limiting plate 205, the movement direction and distance of the ejector block 204 can be limited. At the same time, during the process of the ejector block 204 being squeezed, the limiting spring 206 is squeezed and continues to exert its elastic force. After the threaded cover 3 is separated from the ejector block 204, the limiting spring 206 releases its elastic force, and the ejector block 204 bounces back to its original position, releasing the limitation on the second conduit 104 or the third conduit 6.

[0038] Example 3

[0039] Based on embodiment 1, the regulating tube 2 is provided with a flow groove 201 inside, and two spherical grooves 2011 communicating with the flow groove 201 are opened inside the regulating tube 2. A three-way ball valve 8 is provided inside the spherical groove 2011, and the three-way ball valve 8 is a T-type three-way ball valve. A syringe 4 is fixedly connected to one side of the regulating tube 2. A piston 401 is slidably connected inside the syringe 4. A pull rod 402 is fixedly connected to one side of the piston 401.

[0040] When measuring intra-abdominal pressure in a patient, 20 ml of normal saline needs to be injected into the abdominal cavity to generate a sufficiently large pressure change to accurately detect the intra-abdominal pressure. If the injected amount is too small, the pressure change may be too small to be accurately measured; if the injected amount is too large, it may affect the accuracy of the measurement results and even cause unnecessary discomfort or risks to the patient. At the same time, the volume of normal saline is relatively small and will not significantly increase the patient's intra-abdominal pressure, thus minimizing the impact on the patient, which is especially important for patients who already have high intra-abdominal pressure. During injection, the three-way ball valve 8 is controlled to connect the saline bag 1, the first catheter 101, the three-way tube 102, the second catheter 104, the flow channel 201, and the syringe 4. Then, the piston 401 is moved by the pull rod 402 to draw out the normal saline from the saline bag 1, and the volume of normal saline drawn is precisely controlled by the scale on the syringe 4.

[0041] Then, control the rotation of the two three-way ball valves 8 to connect the syringe 4, the flow channel 201 and the third catheter 6. The third catheter 6 is connected to the urinary catheter on the patient. Then push the lever 402 and the piston 401 to inject 20ml of normal saline inside the syringe 4 into the patient's abdominal cavity through the flow channel 201 and the third catheter 6 to facilitate subsequent intra-abdominal pressure testing.

[0042] Example 4

[0043] Based on Embodiments 1 and 3, a connecting pipe 5 is fixedly connected to one side of the adjusting pipe 2. An interface 501 is provided on one side of the connecting pipe 5, and an annular groove 502 is provided on one side of the connecting pipe 5. A pressing block 503 is slidably connected inside the annular groove 502. A pressing spring 504 is connected between the pressing block 503 and the annular groove 502. A pressing rod 505 is fixedly connected to the side of the pressing block 503 away from the pressing spring 504. An annular block 506 is fixedly connected to one end of the pressing rod 505. The connecting pipe 5... An internal squeezing groove 507 is provided, and the squeezing groove 507 connects the interface 501 and the annular groove 502. A squeezing block 508 is provided inside the squeezing groove 507. A reset groove is provided on the inner wall of the squeezing groove 507. A reset plate 509 is connected to both sides of the squeezing block 508. A reset spring 5091 is connected between the reset plate 509 and the reset groove. A urine tube 701 is provided inside the interface 501. One end of the urine tube 701 is connected to a urine bag 7. An inclined surface is provided at one end of both the pressing block 503 and the squeezing block 508.

[0044] Before pressure testing, insert one end of the urinary catheter 701 into the interface 501 and press the annular block 506. The annular block 506 moves the pressing block 503 through the pressing rod 505, causing the pressing spring 504 to be compressed and accumulate elastic force. At the same time, the pressing block 508 rebounds under the action of the return spring 5091, so that the urinary catheter 701 can be smoothly inserted into the interface 501.

[0045] After the urinary catheter 701 contacts the innermost part of the interface 501, the annular block 506 is released. At this time, the pressing spring 504 releases its elastic force and drives the pressing block 503 to reset. At this time, one end of the pressing block 503 contacts the inclined surface of the squeezing block 508 and presses the squeezing block 508 towards the urinary catheter 701, thus pressing and fixing the urinary catheter 701. Then, during the movement of the squeezing block 508, the direction and distance of movement of the squeezing block 508 can be limited by the setting of the reset groove and the reset plate 509. At the same time, the reset spring 5091 accumulates elastic force under compression. After the pressing block 503 separates from the squeezing block 508, the reset spring 5091 releases its elastic force to push the squeezing block 508 back to its original position. Similarly, when it is necessary to separate the urinary catheter 701 from the connecting pipe 5, the annular block 506 can be pressed to complete the quick connection and disconnection of the urinary catheter 701. This allows the urine bag 7 and the urinary catheter 701 to be disassembled without operating other pipes during subsequent pressure testing.

[0046] After the pressure measurement is completed, the saline solution inside the abdominal cavity needs to be drained. At this time, the third catheter 6 is connected to the connecting tube 5 through the three-way ball valve 8, so that the saline solution inside the abdominal cavity is drained into the urine bag 7 through the third catheter 6, the flow channel 201, the connecting tube 5 and the urine catheter 701.
