Technical Field
[0001] This utility model relates to the field of medical protective clothing testing technology, specifically a device for testing the liquid penetration performance of medical protective clothing. Background Technology
[0002] Medical protective clothing refers to protective garments used by medical personnel (doctors, nurses, public health workers, cleaning staff, etc.) and people entering specific medical and health areas (such as patients, hospital visitors, and people entering infected areas). Its function is to isolate pathogens, harmful ultrafine dust, acidic and alkaline solutions, salt solutions, electromagnetic radiation, etc., ensuring personnel safety and maintaining environmental cleanliness. It is made of PP (polypropylene, accounting for 62% of the total material) non-woven fabric, covered with a special breathable membrane for protective clothing. It has high breathability, anti-static properties, and excellent impermeability. While resisting various organic solvents and acid and alkali corrosion, it also has high impact resistance, strong mechanical properties, a soft and comfortable texture, is non-flammable, non-toxic, non-irritating, and harmless to the skin. Existing liquid penetration performance testing devices for medical protective clothing have some drawbacks: First, the spray test on the protective clothing is insufficient, affecting the test results and leading to poor results; second, it is not easy to fully utilize the test solution, resulting in waste.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a liquid penetration performance testing device for medical protective clothing, comprising an adjustment chamber and a support. The adjustment chamber is disposed on one side of the support. A lead screw is rotatably connected between the upper and lower ends inside the adjustment chamber, and a threaded seat is threaded onto the lead screw. A guide seat is fixed to the front end of the threaded seat, and a conduit is fixed inside the guide seat. A second protective chamber is disposed at the lower end of the adjustment chamber, and a second motor is fixed inside the second protective chamber. The output end of the second motor is fixedly connected to the driving end of the lead screw. A first protective chamber is disposed in the middle of the support, and a first motor is fixed inside the first protective chamber. A support plate is disposed on the upper part of the first protective chamber, and the output end of the first motor is fixedly connected to the driving end of the support plate. Driven by the second motor, the lead screw rotates, thereby driving the threaded seat to rise and fall along the lead screw, thus driving the spray ring to rise and fall, allowing the test solution to be sprayed onto the protective clothing at different heights. Driven by the first motor, the support plate rotates, causing the protective clothing to rotate, which facilitates more thorough contact between the protective clothing and the test solution.
[0005] Preferably, the front end of the adjustment chamber is provided with a guide groove, and the guide groove is slidably connected to the rear end of the guide seat. The adjustment chamber limits the threaded seat through the guide groove to prevent the threaded seat from rotating.
[0006] Preferably, one end of the conduit is connected to a spray ring, and the inner wall of the spray ring is provided with spray nozzles at equal intervals. The test solution is discharged from the spray nozzles through the spray ring and sprayed onto the protective clothing on the mannequin model.

The upper end of the circulation pump is fixedly connected to the lower end of the flow controller. The flow controller can control the liquid flow rate to meet different detection requirements.
[0009] Preferably, a mannequin model is fixed to the upper end of the support plate, and a sieve layer is connected between the protective chamber and the support corresponding to the mannequin model. Several through holes are evenly distributed on the sieve layer, which can allow the test solution to pass through and can also block impurities, so that the test solution can be recycled.
[0010] Preferably, a liquid storage tank is provided at the lower end of the sieve layer, and a connecting pipe is connected between one end of the liquid storage tank and one end of the circulation pump. Under the pumping action of the circulation pump, the test solution passes through the connecting pipe, the circulation pump, and is introduced into the telescopic pipe.
[0011] Preferably, a sliding rod is connected to one side of the bracket, and a slip ring is fixed to the rear end of the conduit. The slip ring is slidably connected to the sliding rod, and the bracket limits the slip ring through the sliding rod, which facilitates the stable lifting and lowering of the spray ring.
[0012] Compared with the prior art, the advantages of this utility model are: better test results and easier utilization of the test solution;
[0013] (1) Driven by motor 2, the lead screw rotates, which in turn drives the threaded seat to rise and fall along the lead screw. The adjusting chamber limits the threaded seat through the guide groove to prevent the threaded seat from rotating, thereby driving the spray ring to rise and fall. The test solution can be sprayed onto the protective clothing at different heights. Subsequently, the bracket limits the slip ring through the slide bar, which is conducive to the stable rise and fall of the spray ring. Driven by motor 1, the support plate rotates, which drives the protective clothing to rotate, which is conducive to the protective clothing and the test solution to come into full contact, resulting in a good test effect. (2) Under the action of the circulating pump, the test solution is introduced into the telescopic tube through the connecting pipe and the circulating pump. The telescopic tube is telescopic, which is conducive to the lifting and lowering of the guide tube with the threaded seat, thus improving the flexibility of the device. The test solution is discharged from the spray nozzle through the spray ring and sprayed onto the protective clothing on the mannequin model. Subsequently, there are several through holes evenly distributed on the sieve layer, which can allow the test solution to pass through and can also block impurities, so that the test solution can be recycled and easily made full use of the test solution.
