Description

Technical Field

[0001] This utility model relates to the field of medical product testing technology, specifically an airtightness testing device. Background Technology

[0002] Hemostatic clips and infusion tubing are two commonly used medical devices. Infusion tubing is usually made of soft material and can be used to administer intravenous fluids to patients with the help of a needle. Hemostatic clips are used to prevent bleeding. In order to ensure that these two devices can be used normally, they need to be tested during the production and processing.

[0003] When testing the airtightness of medical devices such as infusion tubing, the existing testing device is based on a processing table with the testing equipment body installed on the top side of the processing table. The output end of the testing equipment body is connected to a tubing, and a connector is fixed to one end of the tubing. During testing, the operator connects the tubing to the infusion tubing to be tested with the help of the connector, and the testing equipment inflates it. The airtightness of the product is detected by the change in air pressure. This device has a simple structure and is easy to use.

[0004] However, current testing devices only allow operators to test a single infusion tube during the testing process, resulting in low testing efficiency and reduced production efficiency of the medical product. Therefore, an airtightness testing device is proposed. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the testing devices on the market only allow operators to test a single infusion tube during the testing process, resulting in low testing efficiency and reduced production efficiency of the medical product. This utility model proposes an airtightness testing device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The airtightness testing device of this utility model includes a bracket; a testing mechanism is provided on the inner side of the bracket, an auxiliary mechanism is provided on the bottom side of the bracket, a limiting mechanism is provided on the top side of the bracket, and slide rails are symmetrically fixed on the inner side of the bracket.

[0007] Preferably, the testing mechanism includes a slide rail, on which a slider is slidably mounted. Fixed plates are symmetrically fixed on both sides of the slider. A hollow tube is fixed inside the slider, and a guide tube is uniformly fixed on one side of the hollow tube, with the guide tube inserted through the side of one fixed plate. An inflation head is fixed to one end of the guide tube. A support plate is fixed to the top of the side of the support, and an electric telescopic rod is fixed to the side of the support plate. The output end of the electric telescopic rod passes through the support plate and is fixedly connected to the fixed plate, and is slidably connected to the support plate. A base plate is fixed to the bottom of the support. Through the cooperation of the slide rail and the slider, multiple inflation heads can be moved to the testing position, enabling simultaneous testing of multiple products, thereby improving the production and processing efficiency of medical products.

[0008] Preferably, the auxiliary mechanism includes a base plate, an air pump fixed to the top side of the base plate, an air supply pipe fixed to the output end of the air pump, one end of the air supply pipe communicating with the inside of a hollow tube, a rectangular plate fixed to the side of the support, a glass tube fixed to the inside of the rectangular plate, a piston slidably mounted inside the glass tube, a spring fixedly connected between the piston and one end of the glass tube, one end of the glass tube communicating with the inside of the air supply pipe through a guide pipe, a graduated groove formed on the circumference of the glass tube, and a support frame fixed to the top of the support. By using the glass tube and piston in conjunction, the pressure of the air pump during testing is measured according to the position of the piston in the graduated groove, thereby preventing leakage of the air supply pipe and affecting the accuracy of the test results.

[0009] Preferably, the limiting mechanism includes a support frame, a top plate fixed to the inner side, a first cylinder fixed to the side of the top plate, a first lifting platform fixed to the bottom output end of the first cylinder, a limiting plate fixed to the side of the support frame, a second cylinder fixed to the side of the limiting plate, a second lifting platform fixed to the top output end of the second cylinder, and clamping plates fixed to the inner sides of the first and second lifting platforms. Through the structure of the cylinder and the lifting platform, the clamping plates can be moved to contact the product to be tested, thereby limiting its movement and enabling testing, thus improving the testing efficiency of the device.

[0010] The advantages of this utility model are:

[0011] 1. This utility model, through the structural design of an airtightness testing device, sets up a testing mechanism and controls the electric telescopic rod to extend, thereby pushing the fixed plate to slide along the slide rail with the cooperation of the slider, thereby driving multiple inflation heads to extend and connect with the product to be tested. With the cooperation of the air pump and the hollow tube, air is introduced into the product through the conduit to test its airtightness. This structure can realize the function of simultaneously and automatically testing multiple products, solving the problem of low production and processing efficiency of existing equipment.

[0012] 2. This utility model, through the structural design of an airtightness testing device, uses an auxiliary mechanism to turn on the air pump, allowing it to output air through the air supply pipe. Since the glass tube is connected to the inside of the air supply pipe, changes in the internal air pressure push the piston to move horizontally inside the glass tube, compressing or stretching the spring. By observing the position of the piston in the graduated groove, the extension and contraction length of the spring can be measured, thereby determining the change in air pressure inside the air supply pipe and identifying any leaks, ensuring the accuracy of the product's airtightness test results.

[0020] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0021] Please see Figure 1-4 As shown, an airtightness testing device includes a bracket 1; a testing mechanism is provided on the inner side of the bracket 1, an auxiliary mechanism is provided on the bottom side of the bracket 1, a limiting mechanism is provided on the top side of the bracket 1, and slide rails 2 are symmetrically fixed on the inner side of the bracket 1.

[0022] Please see Figure 2 As shown, the detection mechanism includes a slide rail 2, on which a slider 3 is slidably mounted. Fixing plates 4 are symmetrically fixed on both sides of the slider 3. A hollow tube 5 is fixed inside the slider 3. A guide tube 6 is evenly fixed on one side of the hollow tube 5, and the guide tube 6 is inserted through the side of one fixing plate 4. An inflation head 7 is fixed to one end of the guide tube 6. A support plate 8 is fixed to the top of the side of the bracket 1. An electric telescopic rod 9 is fixed to the side of the support plate 8. The output end of the electric telescopic rod 9 passes through the support plate 8 and is fixedly connected to the fixing plate 4, and the output end of the electric telescopic rod 9 slides against the support plate 8. The support 1 is connected to a base plate 10 fixed at its bottom end. During operation, when the existing equipment has low production efficiency, the structure of the detection mechanism controls the electric telescopic rod 9 to extend, thereby pushing the fixed plate 4 to slide along the slide rail 2 with the cooperation of the slider 3. This causes multiple inflation heads 7 to extend and connect with the product to be tested. With the cooperation of the air pump 11 and the hollow tube 5, air is introduced into the product through the conduit 6 to test its airtightness. This structure can realize the function of automatically testing multiple products at the same time, thereby improving the production efficiency of medical products.

[0023] Please see Figure 3 As shown, the auxiliary mechanism includes a base plate 10, an air pump 11 fixed to the top side of the base plate 10, an air supply pipe 12 fixed to the output end of the air pump 11, one end of the air supply pipe 12 communicating with the inside of the hollow tube 5, a rectangular plate 13 fixed to the side of the bracket 1, a glass tube 14 fixed to the inside of the rectangular plate 13, a piston 15 slidably mounted on the inside of the glass tube 14, a spring 16 fixedly connected between the piston 15 and one end of the inside of the glass tube 14, one end of the glass tube 14 communicating with the inside of the air supply pipe 12 through an air guide pipe 18, and a graduated groove 17 opened on the circumferential surface of the glass tube 14. A support frame 19 is fixed at the top of the bracket 1. During operation, when encountering problems such as inaccurate test results due to pipeline leakage, the air pump 11 is turned on through the structure of the auxiliary mechanism, so that it outputs air through the air supply pipe 12. Since the glass tube 14 is connected to the inside of the air supply pipe 12, when the air pressure inside changes, it pushes the piston 15 to move inside the glass tube 14, so that it compresses or stretches the spring 16. By observing the position of the piston 15 in the scale groove 17, the extension and contraction length of the spring 16 is measured, thereby knowing the change in air pressure inside the air supply pipe 12, judging its leakage, and ensuring the accuracy of the product's airtightness test results.

[0024] Please see Figure 4 As shown, the limiting mechanism includes a support frame 19, a top plate 20 fixed to the inner side, a first cylinder 21 fixed to the side of the top plate 20, a first lifting platform 22 fixed to the bottom output end of the first cylinder 21, a limiting plate 23 fixed to the side of the support frame 1, a second cylinder 24 fixed to the side of the limiting plate 23, a second lifting platform 25 fixed to the top output end of the second cylinder 24, and a clamping plate 26 fixed to the inner side of the first lifting platform 22 and the second lifting platform 25. During operation, if the product position shifts during the testing process, preventing testing, the limiting mechanism, through its structure, controls the first cylinder 21 or the second cylinder 24 to move the output end of the first lifting platform 22 or the second lifting platform 25, causing the product to be positioned within the groove inside the clamping plate 26, thus limiting its position. Then, the product is tested, preventing position shift during testing and ensuring that the testing efficiency and accuracy of the device do not decrease.

[0025] Please see Figure 5 As shown, the support 1 has threaded holes 28 evenly distributed on its side. The limiting plate 23 is fixedly installed on the side of the threaded holes 28 by bolts 27. During operation, when the existing processing equipment has a limited range of application, the limiting plate 23 is fixed by the structure of the threaded holes 28 and bolts 27, so that it can be installed in a suitable position as needed. This allows the second lifting platform 25 on the top side of the second cylinder 24 to move more widely, thus making it suitable for various production lines and expanding the scope of application of the equipment.

[0026] Working Principle: Hemostatic clips and infusion tubing are two commonly used medical devices. Infusion tubing, typically made of soft materials, allows for intravenous infusion with the aid of a needle, while hemostatic clips prevent bleeding. To ensure proper functioning, these devices require testing during manufacturing. Existing testing devices only allow operators to test a single infusion tubing, resulting in low testing efficiency and consequently reduced production efficiency. To address this, a testing and auxiliary mechanism is implemented. The product to be tested is moved between the two clamping plates 26. The first cylinder 21 or the second cylinder 24 is controlled to move the first lifting platform 22 or the second lifting platform 25 at the output end, causing the product to be positioned within the groove on the inner side of the clamping plate 26, thus limiting its movement. Then, the electric telescopic rod 9 is extended, thereby controlling the slider... With the cooperation of 3, the fixed plate 4 is pushed to slide along the slide rail 2, thereby driving multiple inflation heads 7 to extend and connect with the product to be tested. With the cooperation of air pump 11 and hollow tube 5, air is introduced into the product through conduit 6 to test its airtightness. During the test, since the glass tube 14 is connected to the inside of the air supply pipe 12, when the air pressure inside changes, the piston 15 is pushed to move inside the glass tube 14, which compresses or stretches the spring 16. By observing the position of the piston 15 in the scale groove 17, the extension and contraction length of the spring 16 is measured, thereby knowing the change in air pressure inside the air supply pipe 12 and judging its leakage, ensuring the accuracy of the product airtightness test results. Finally, the electric telescopic rod 9 is controlled to retract the inflation head 7, and the first cylinder 21 or the second cylinder 24 is controlled to reset the clamp 26, release the limit on the product, and output the tested product, which solves the problem of low production and processing efficiency of existing equipment.
