Description

Technical Field

[0001] The utility model relates to the technical field of medical glove testing equipment, in particular to a medical glove water tightness testing equipment. Background Art

[0002] Medical gloves are widely used as protective tools around the world. Governments and relevant regulatory agencies have set corresponding standards for the quality of medical gloves to ensure their effectiveness and safety.

[0003] Among them, glove water tightness testing is an important test item for medical gloves and is an evaluation indicator for avoiding cross-contamination between patients and users in the medical field.

[0004] There are differences in the water tightness testing standards for medical gloves in the world's three major markets: the United States, the European Union, and China.

[0005] 1. The water tightness test of medical gloves in the United States is carried out according to ASTM D5151-2019. The test steps of this method are as follows:

[0006] (1) Make sure the outside of the gloves remains dry.

[0007] (2) Install the cuff onto the test tube, with the cuff no more than 40 mm from the bottom of the plastic tube. When the tube is filled with water, the rest of the glove should hang freely.

[0008] (3) Pour at least 1000cm 3 Room temperature water (20-30°C), water should enter the gloves freely.

[0009] (4) Visually check the gloves for leaks, let the gloves hang for 2 minutes, and check again for leaks.

[0010] 2. The EU medical gloves water tightness test is carried out according to EN 455-1-2020. The test steps of this method are as follows:

[0011] (1) Install the gloves on a suitable tube and vertically pour (1000±50)ml of water into the gloves.

[0012] (2) The water temperature should be controlled at (15-35)°C. Water should flow freely into the glove, ensuring that each finger flows evenly. During the test, some water may remain in the filling tube.

[0013] (3) Check the gloves for water leakage immediately, and then observe again within 2 to 3 minutes. Leakage within 40 mm of the cuff is the criterion for judging whether the test has failed.

[0014] 3. The water tightness test of disposable medical rubber examination gloves in China is carried out according to GB 10213-2006. The test steps of this method are as follows:

[0015] Use a suitable device, such as an O-ring, to tie the glove to the cylinder so that the glove does not extend beyond 40 mm of the cylinder. Introduce 1000 mL ± 50 mL of water, not exceeding 36 ° C, into the device and wipe off any splashed water on the glove. If the water cannot rise to 40 mm from the cuff, raise the glove to ensure that the entire glove (including the part 40 mm from the cuff) is tested. Pay attention to any obvious leakage immediately. If there is no immediate leakage, observe for another 2 minutes to 4 minutes. Ignore leakage within 40 mm from the cuff. For easy observation, the water can be dyed with a water-soluble dye.

[0016] From the perspective of the water tightness test standards of medical gloves in the three regions, the main differences are as follows:

[0017] standard Water volume Water temperature Observation time ASTM D5151-2019 ≥1000ml (20-30)℃ 2 minutes EN 455-1-2020 (950-1050)ml (15-35)℃ 2-3 minutes GB 10213-2006 (950-1050)ml ≤36℃ 2-4 minutes

[0018] The utility model designs a detection tool, which can use one set of tool to simultaneously meet the requirements of three standards for water tightness testing of ASTM D5151-2019, EN 455-1-2020, and GB 10213-2006. Utility Model Content

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0040] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix", "join", "hinge" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] A medical glove water tightness testing device, such as Figure 1 to Figure 2 As shown, it includes four main components: a water tank 110, a medical glove assembly cylinder 211, a flow meter 210, a post-test water receiving tank 310, and a timer 311. The water tank 110 is equipped with a heating temperature control device 111, the medical glove assembly cylinder 211 is equipped with a flow meter 210, and a timer 311 is installed on the side of the post-test water receiving tank.

[0042] The water tank 110 is in the shape of a rectangular parallelepiped, and is equipped with a heating and temperature control device to ensure that the water temperature can meet the standard requirements. Figure 2, the water tank 110 extends downwardly out of 10 cylindrical connecting parts 112, so as to facilitate interconnection with the medical glove assembly cylinder 211, so the device can connect 10 medical glove assembly cylinders 211, thereby improving the detection efficiency. In other embodiments, the shape of the water tank 110 can also be other shapes, and more cylindrical connecting parts 112 can be added to increase the number of medical glove cylinders 211 that can be connected. At the same time, in other embodiments, the body of the medical glove assembly cylinder may be other shapes, such as an elliptical cylinder. In any embodiment, the connecting part provided in the water tank 110 should match the body shape of the medical glove assembly cylinder. Furthermore, a water inlet can be added to the side of the water tank 110, so that there is no need to manually add test water for each test, thereby improving the detection efficiency.

[0043] like Figure 1 As shown, the medical glove assembly cylinder 211 is connected to the water tank 110, and a flow meter 210 is installed on the medical glove assembly cylinder 211 to ensure that the amount of water added to the gloves during the test can meet the standard requirements. The flow meter 210 is arranged in the hollow structure of the medical glove assembly cylinder 211, and has a device that can open or close the water flow passage inside the medical glove assembly cylinder. The medical glove assembly cylinder 211 is made of glass or other transparent materials. When the test water flows into the cylinder, the flow rate can be visually observed, so as to judge the accuracy of the data of the flow meter 210.

[0044] like Figure 1 As shown, the post-test water receiving tank 310 has a rectangular body structure. In other embodiments, the post-test water receiving tank 310 may also be in other shapes. The post-test water receiving tank 310 should be able to receive all the water flowing out of the medical glove cylinder 211 or the medical glove cylinder 211 after the gloves are put on. The slot area should be large enough. The post-test water receiving tank 310 is equipped with a timer 311 on the outer side of the tank body to monitor the water tightness test observation time.

[0045] When the medical glove water tightness testing device is used normally, the water tank 110 is connected to the medical glove assembly cylinder 211 and is suspended above the post-test water receiving tank 310, and is at a certain distance from the post-test water receiving tank 310. This distance should be sufficient to allow the gloves to hang down naturally without folding during the test. The diameter of the lower cylinder opening of the medical glove assembly cylinder 211 should not be too large, otherwise excessive deformation of the medical gloves will affect the accuracy of the test results.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical scheme and concept of the present invention within the scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
