Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a pressure stabilizing gas container for a medical pneumoperitoneum machine. Background Technology

[0002] Medical insufflators are specialized air supply devices for minimally invasive surgeries such as laparoscopy, thoracoscopy, and hysteroscopy. When liquid carbon dioxide vaporizes through a pressure reducing valve, its temperature drops sharply, causing significant pressure fluctuations. Repeated insertion and removal of instruments, incomplete cannula sealing, and fume extraction from electrosurgical units can all lead to instantaneous air leakage. Without buffering, the abdominal pressure can immediately limit the field of vision, affecting the surgical outcome. Therefore, a pressure-stabilizing gas container is necessary for medical insufflators.

[0003] The gas pressure stabilizing device for medical insufflators is a device for stabilizing the pressure of medical insufflators. In previous technologies, a buffer chamber was usually set up to stabilize the pressure of the insufflator. The gas capacity of the buffer chamber was usually fixed and could not be flexibly adjusted, which limited the gas pressure stabilization and could not effectively stabilize the pressure. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a gas pressure stabilizing device for a medical pneumoperitoneum machine, which aims to improve the problem that the gas capacity of the pneumoperitoneum machine cavity is usually fixed and cannot be flexibly adjusted, which limits the ability to effectively stabilize the gas pressure.

[0028] Specifically, the gas chamber 1 is the part of the device used to store gas. Inside the gas chamber 1, there is a regulating plate 2, which can be used to adjust the volume of the gas chamber 1 and play a role in stabilizing pressure.

The regulating plate 2 can drive the connecting block 3 to move, the connecting block 3 can drive the rotating shaft 4 to move, and the rotating shaft 4 can drive the rotating plate 5 to rotate. The rotating plate 5 rotates on the outer wall of the rotating shaft 6, and the rotating shaft 6 can drive the sliding block 7 to slide on the outer wall of the support column 8.

The control plate 2 can be driven to slide inside the gas cavity 1 by the compression of the gas. The control plate 2 can drive the sliding column 1301 to slide inside the telescopic rod 1302. When the sliding column 1301 slides, it can drive the first spring 1303 to be compressed. The first spring 1303 plays a rebound role, which can drive the control plate 2 to slide stably and ensure the pressure stabilization effect.

[0035] Specifically, a proportional valve 16 is installed above the gas chamber 1. The proportional valve 16 can precisely regulate the intake gas and inject the depressurized carbon dioxide from upstream into the gas chamber 1 at a set flow rate. An exhaust valve 17 is installed above the gas chamber 1 to actively exhaust and regulate the release of carbon dioxide quickly and controllably. A pressure detection port 19 is installed on the outer wall of the gas chamber 1 for real-time pressure monitoring. A vent valve 20 is installed above the gas chamber 1 for venting the gas.

[0036] Example 3:

[0037] Reference Figure 5 and Figure 6An installation block 21 is fixedly connected to the outer wall of the vent valve 20, and the outer wall of the installation block 21 is slidably connected to the inside of the gas cavity 1. A slide rod 22 is slidably connected inside the installation block 21, and a connecting plate 23 is fixedly connected to the lower surface of the slide rod 22. A connecting shaft 24 is fixedly connected inside the connecting plate 23. A rotating plate 25 is rotatably connected to the outer wall of the connecting shaft 24, and a support shaft 26 is rotatably connected inside the rotating plate 25. A sliding plate 27 is fixedly connected to the outer wall of the support shaft 26, and the outer wall of the sliding plate 27 is slidably connected to the inside of the gas cavity 1. A second spring 28 is provided on the outer wall of the sliding plate 27, and the outer wall of the second spring 28 is fixedly connected to the inside of the gas cavity 1. A locking block 29 is fixedly connected to the outer wall of the sliding plate 27, and the outer wall of the locking block 29 is slidably connected to the inside of the gas cavity 1.

[0038] Specifically, the vent valve 20 serves to fix the mounting block 21. The mounting block 21 is used to install and fix the vent valve 20. By moving the mounting block 21 into the gas chamber 1, a locking block 29 is provided inside the mounting block 21. The rebound action of the second spring 28 can drive the locking block 29 to engage with the gas chamber 1, thereby achieving the effect of quick installation of the vent valve 20. By pressing the slide rod 22, the connecting plate 23 can be moved. The connecting plate 23 can be moved, which in turn can move the connecting shaft 24. The connecting shaft 24 can be moved, which in turn can rotate the rotating plate 25 on the outer wall of the support shaft 26. The rotating plate 25 can be moved, which in turn can move the support shaft 26. The support shaft 26 can be moved, which in turn can move the sliding plate 27 inside the gas chamber 1. The sliding plate 27 can be moved, which can also move the locking block 29. By moving the locking block 29 into the mounting block 21, the vent valve 20 can be quickly disassembled. This allows for quick confirmation of whether the valve body is faulty. After disassembly, cleaning can thoroughly sterilize the valve and prevent cross-infection.

[0039] Working principle: When this pressure-stabilizing gas capacity device is needed, carbon dioxide is first discharged from the inlet 15, heated by the heating module 14, and then enters the gas capacity cavity 1 to stabilize the gas pressure. When the high-frequency switching proportional valve 16 is turned on, an increased pressure difference is formed, and the gas capacity in the gas capacity cavity 1 changes accordingly. The gas will drive the control plate 2 to slide inside the gas capacity cavity 1. When the control plate 2 slides, it can drive the control plate 2 to slide on the outer wall of the limit rod 11, and at the same time drive the second spring 12 to be compressed, thereby driving the rotating plate 5 to rotate on the outer wall of the rotating shaft 4 and the rotating shaft 6. At the same time, it can drive the outer wall of the support column 8 to slide, thereby driving the first spring 10 to reciprocate on the outer wall of the fixed plate 9, so as to achieve the effect of flexibly adjusting the gas capacity and achieving the effect of effective pressure stabilization.

[0040] When the vent valve 20 needs to be disassembled, pressing the slide bar 22 can move the connecting plate 23, which in turn causes the rotating plate 25 to rotate on the outer wall of the connecting shaft 24. When the rotating plate 25 rotates, it can move the support shaft 26, and at the same time, it can cause the sliding plate 27 to slide inside the gas chamber 1, which in turn causes the second spring 28 to be compressed, and at the same time, it causes the locking block 29 to slide into the interior of the mounting block 21. At this time, by causing the mounting block 21 to slide out of the interior of the gas chamber 1, the vent valve 20 can be quickly disassembled to check whether the valve body is faulty. After disassembly, cleaning can thoroughly sterilize and avoid cross-infection. This device can not only achieve the effect of flexibly adjusting the gas capacity and effectively stabilizing the pressure, but also achieve the effect of quickly disassembling the vent valve 20, so that cleaning can be carried out after disassembly, and thorough sterilization can be achieved to avoid cross-infection.
