Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical equipment, specifically to a dual-purpose device for bladder irrigation and intra-abdominal pressure monitoring. Background Technology
[0002] Bladder irrigation is a medical procedure primarily used to maintain unobstructed urinary drainage in patients with indwelling catheters, remove blood clots, mucus, bacteria, and other foreign bodies from the bladder, and treat certain bladder diseases. Bladder irrigation involves using a catheter to deliver irrigation fluid into the bladder, followed by drainage. Currently, the most common clinical method for bladder irrigation is to deliver the irrigation fluid into the bladder via an infusion set through a catheter, which makes it difficult to accurately control the dosage of irrigation fluid delivered each time.
[0003] Intra-abdominal pressure (IAP) is the pressure within the abdominal cavity. Under normal circumstances, it is equal to or slightly higher than atmospheric pressure. Any condition that increases the volume of abdominal contents can increase IAP. Intra-abdominal infections, ascites, and other causes can lead to elevated IAP, and in severe cases, abdominal compartment syndrome, a very serious clinical complication. Therefore, monitoring IAP is crucial for patients with elevated IAP due to intra-abdominal infections, ascites, or other causes. Summary of the Invention
[0004] The main purpose of this invention is to propose a dual-purpose device for bladder irrigation and intra-abdominal pressure monitoring, which can perform both bladder irrigation and intra-abdominal pressure monitoring.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A dual-purpose device for bladder irrigation and intra-abdominal pressure monitoring includes an infusion tube, a reservoir, a pressure measuring tube, and a drainage tube. The reservoir has a first graduation mark starting from the bottom of the reservoir, and an exhaust pipe is located at the top of the reservoir. The pressure measuring tube has a second graduation mark starting from the bottom of the pressure measuring tube. The infusion tube, pressure measuring tube, and drainage tube are connected by two three-way valves.
[0007] The first graduation range is between 0 and 100 ml.
[0008] The second scale has a range of 0 to 40 centimeters.
[0009] The exhaust pipe is equipped with a switch clamp.
[0010] The pressure measuring tube is equipped with a switch clamp.
[0011] An infusion piston is installed on the infusion tube, and the infusion piston is located above the reservoir.
[0012] This utility model provides a dual-purpose device for bladder irrigation and intra-abdominal pressure monitoring, which has the following beneficial effects: by setting a reservoir with a first scale on the reservoir and a second scale on the pressure measuring tube, the reservoir can store a certain amount of liquid. During bladder irrigation, the dosage of irrigation fluid can be controlled. During intra-abdominal pressure monitoring, the dosage of liquid delivered to the bladder before intra-abdominal pressure monitoring can be controlled. The height of the liquid column in the second scale can directly reflect the intra-abdominal pressure. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. In the description of this utility model, it should be noted that the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0016] like Figure 1 As shown, the device is a dual-purpose device for bladder irrigation and intra-abdominal pressure monitoring. The device includes an infusion tube 3, a reservoir 4, a pressure measuring tube 7, and a drainage tube 11.
[0017] An infusion piston 2 is provided on the infusion tube 3. A first scale 14 is provided on the reservoir 4, with the bottom of the reservoir 4 as the starting point. An exhaust pipe 5 is provided on the top of the reservoir 4. A first switch clamp 6 is provided on the exhaust pipe. A second scale 15 and a second switch clamp 8 are provided on the pressure measuring tube 7, with the bottom of the pressure measuring tube 7 as the starting point. A third switch clamp 12 is provided on the drainage tube 11. The infusion tube 3, the pressure measuring tube 7, and the drainage tube 11 are connected by a first three-way valve 9 and a second three-way valve 10.
[0018] The puncture body 1 can be connected to a container holding bladder irrigation fluid or intra-abdominal pressure monitoring fluid.
[0019] The first graduation 14 has a graduation range between 0 and 100 ml. The first graduation 14 is used to indicate the dosage of the liquid contained in the reservoir 4. It can control the dosage of the irrigation fluid during bladder irrigation and the dosage of the fluid delivered to the bladder before intra-abdominal pressure monitoring during intra-abdominal pressure monitoring.
[0020] The second graduation 15 has a range of 0 to 40 centimeters. The height of the liquid column in the second graduation 15 directly reflects the intra-abdominal pressure.
[0021] During bladder irrigation, first close the infusion piston 2 and the second switch clamp 8. Rotate the second three-way valve 10 to close the connection between the second three-way valve 10 and the infusion tube 3. Rotate the first three-way valve 9 to close the connection between the first three-way valve 9 and the pressure measuring tube 7. Open the first switch clamp 6 to allow the reservoir 4 to communicate with the atmosphere. Open the infusion piston 2, add the required dose of irrigation solution into the reservoir 4, and then close the infusion piston 2. Rotate the second three-way valve 10 to connect the infusion tube 3 with the urinary catheter end of the drainage tube 11. The irrigation solution flows through the infusion tube 3 and the urinary catheter end of the drainage tube 11 into the urinary catheter and then into the bladder. After a period of treatment, rotate the second three-way valve 10 to close the connection between the second three-way valve 10 and the infusion tube 3. At this time, the urinary catheter end of the drainage tube 11 is connected to the drainage bag end of the drainage tube 11. The irrigation solution flows through the drainage tube 11 into the drainage bag 13, completing one bladder irrigation.
[0022] During intra-abdominal pressure monitoring, first close the infusion piston 2 and the second switch clamp 8. Rotate the second three-way valve 10 to close the connection between the second three-way valve 10 and the infusion tube 3. Rotate the first three-way valve 9 to close the connection between the first three-way valve 9 and the pressure measuring tube 7. Open the first switch clamp 6 to allow the reservoir 4 to communicate with the atmosphere. Open the infusion piston 2, add the required dose of intra-abdominal pressure monitoring fluid into the reservoir 4, and then close the infusion piston 2. Rotate the second three-way valve 10 to connect the infusion tube 3 with the urinary catheter end of the drainage tube 11. The intra-abdominal pressure monitoring fluid flows into the urinary catheter and then into the bladder through the infusion tube 3 and the urinary catheter end of the drainage tube 11. Rotate the first three-way valve 9 to connect the pressure measuring tube 7 with the urinary catheter end of the drainage tube 11. Place the pressure measuring tube 7 vertically and open the second switch clamp 8. At this time, the fluid in the bladder flows into the pressure measuring tube 7 under the action of abdominal pressure. The height of the liquid column at the second scale 15 on the pressure measuring tube 7 can directly reflect the intra-abdominal pressure, thus completing one intra-abdominal pressure monitoring.
[0023] This invention features a reasonable design that accurately controls the dosage of fluid delivered to the bladder during bladder irrigation and intra-abdominal pressure monitoring. This reduces complications caused by excessive fluid delivery during bladder irrigation and errors due to inaccurate fluid delivery dosage during intra-abdominal pressure monitoring. Furthermore, the device is simple to operate, and its integrated design reduces the risk of infection. It improves the efficiency of bladder irrigation and intra-abdominal pressure monitoring, facilitating clinical work and enhancing both efficiency and quality.
[0024] The above description is only used to illustrate the technical solution of this utility model, and not to limit it. Those skilled in the art should understand that they can still modify the technical solution of this utility model or make equivalent substitutions for some of its technical features, and these modifications or substitutions do not cause the essence of the corresponding technical solution to deviate from the spirit and scope of the technical solution of this utility model.
