Description

Technical Field

[0001] This utility model belongs to the field of ventilator technology, specifically a leak testing device for ventilators. Background Technology

[0002] Leak testing equipment for ventilators is widely used in hospital respiratory therapy departments, emergency centers, ICU wards, and medical device manufacturers. In these settings, the performance and sealing of ventilators are directly related to the patient's treatment outcome and life safety, making regular leak testing particularly important.

[0003] Leak testing equipment for ventilators primarily tests the sealing of the breathing tubing by simulating the pressure and flow environment during ventilator operation. Its core principle is based on high-precision gas flow measurement technology. By injecting gas at a certain pressure into the tested tubing and monitoring the difference in gas flow inside and outside the tubing, it determines whether a leak exists.

[0004] In current technologies, when leak testing of ventilators, the breathing tubing is usually tested for tightness. During the test, the breathing tubing is installed at the end of the testing device for tightness testing. However, during the long-term testing process, the end of the breathing tubing is compressed, which can cause the skin to bend and break, thereby reducing the accuracy of the ventilator's tightness test. Therefore, a leak testing device for ventilators is proposed to address the above problems. Utility Model Content

[0012] 1. This utility model provides a leak testing device for ventilators. The device involves a breathing tube that passes through the interior of a guide tube and is then installed inside a test mounting hole. Upon completion of the penetration, clamping rods on both sides of the guide tube are squeezed to open them and engage with both sides of the breathing tube. This provides support and guidance for the tail end of the breathing tube, reducing the risk of skin breakage due to bending at the tail end during prolonged installation, which could lower the detection accuracy of the ventilator leak detection device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figures 1-4 This utility model provides a leak testing device for a ventilator, including a ventilator leak detection device 1. The ventilator leak detection device 1 has a fixing unit installed inside. A support frame 21 is installed at the end of the ventilator leak detection device 1 via the fixing unit. A guide tube 22 is fixedly connected to the end of the support frame 21. Several clamping rods 23 are hinged to both sides of the guide tube 22 via torsion springs. A test mounting hole 25 is provided at the end of the ventilator leak detection device 1. During operation, when it is necessary to detect a leak in the ventilator, the ventilator tubing is inserted into the test mounting hole 25. During installation, the breathing tubing passes through the guide tube 22 and is then installed inside the test mounting hole 25. After the passage is complete, the clamping rods 23 on both sides of the guide tube 22 are squeezed, causing the clamping rods 23 to open to both sides and engage with both sides of the breathing tubing. This supports and guides the tail end of the breathing tubing, reducing the risk of the tail end bending and causing skin breakage during long-term installation, thus improving the detection accuracy of the ventilator leak detection device 1.

[0024] Furthermore, such as Figures 3-4As shown, the fixing unit includes a snap-fit ​​groove 31; the ventilator leak detection device 1 has a snap-fit ​​groove 31 inside; a snap-fit ​​block 32 is fixedly connected to the end of the support frame 21; a locking groove 33 is opened inside the snap-fit ​​block 32; a cavity 34 is opened inside the ventilator leak detection device 1; a locking block 35 is slidably connected inside the cavity 34; a spring 36 is fixedly connected to the end of the locking block 35, and the other end of the spring 36 is fixedly connected to the inner wall of the cavity 34; during operation, when the support frame 21 needs to be installed, the support frame 21 is placed at the end of the ventilator leak detection device 1, which drives the snap-fit ​​block 32 to be inserted into the snap-fit ​​groove 31. During the insertion process, the locking block 35 is squeezed, causing the locking block 35 to be compressed and contracted into the cavity 34, compressing the spring 36 to generate elastic force. When the locking groove 33 and the cavity 34 are aligned, the elastic force generated by the spring 36 pushes the locking block 35 into the locking groove 33 for snap-fit ​​fixing, thereby quickly installing and fixing the support frame 21.

[0025] Furthermore, such as Figures 3-4 As shown, a pull rod 41 is fixedly connected to the end of the locking block 35; a handle 42 is fixedly connected to the end of the pull rod 41. During operation, when the support frame 21 needs to be disassembled, the pull rod 41 is pulled to drive the handle 42 to slide, so that the handle 42 pulls the locking block 35 to retract into the cavity 34, thereby sliding the support frame 21 and the locking block 32 out of the locking groove 31 for quick disassembly.

[0026] Furthermore, such as Figures 1-2 As shown, the end of the locking block 35 is semi-arc-shaped and matches the locking groove 33; the end of the clamping rod 23 is fixed with a protective pad 24, and the end of the protective pad 24 is semi-arc-shaped; during operation, by installing the protective pad 24 at the end of the clamping rod 23, the clamping rod 23 can play a protective role when supporting the breathing tube.

[0027] Furthermore, such as Figures 1-2 As shown, the bottom of the ventilator leak detection device 1 is fixedly connected to a support leg 51, and there are several of them; the bottom of the support leg 51 is fixedly connected to a support plate 52; during operation, by installing several support legs 51 and support plates 52 at the bottom of the ventilator leak detection device 1, the overall stability of the ventilator leak detection device 1 is improved.

[0028] Working principle: When leak detection of the ventilator is required, the ventilator tubing is inserted into the test mounting hole 25. During installation, the tubing passes through the guide tube 22 and is then installed inside the test mounting hole 25. Upon completion of the penetration, the clamping rods 23 on both sides of the guide tube 22 are squeezed, causing them to open and engage with both sides of the tubing. This supports and guides the end of the tubing, reducing the risk of bending and skin breakage at the end during prolonged installation, which could reduce the detection accuracy of the ventilator leak detection device 1. When the support frame 21 needs to be installed, it is placed at the end of the ventilator leak detection device 1, causing the locking block 32 to be inserted into the locking groove 31. During insertion, the locking block 35 is squeezed, causing it to be subjected to pressure. The compression spring 36 inside the cavity 34 generates elastic force. When the locking groove 33 and the cavity 34 are aligned, the elastic force generated by the spring 36 pushes the locking block 35 into the locking groove 33 for locking and fixing, thereby quickly installing and fixing the support frame 21. When the support frame 21 needs to be disassembled, the pull rod 41 is pulled to drive the handle 42 to slide, causing the handle 42 to pull the locking block 35 to retract into the cavity 34, thereby sliding the support frame 21 and the locking block 32 out of the locking groove 31 for quick disassembly. The protective pad 24 installed at the end of the clamping rod 23 provides protection when supporting the breathing tube. Several support legs 51 and support plates 52 are installed at the bottom of the ventilator leak detection device 1 to improve the overall stability of the ventilator leak detection device 1.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
