Description
Technical Field
[0001] The invention relates to the technical field of sterility detection, in particular to a sterility detection device. Background Art
[0002] Sterility testing equipment is a specialized device used to detect and ensure the presence of microbial contamination in samples, products, or environments. These devices are critical in many industries, especially in the fields of pharmaceuticals, food, medical devices, cosmetics, etc., where the sterility of the product is crucial. Sterility testing equipment can help ensure product quality and ensure consumer safety; and one of the main applications of incubators is sterility testing. By placing suspected contaminated samples (such as drugs, medical devices, foods, etc.) in an incubator and observing whether there is microbial growth, it can be determined whether the sample meets the sterility standard.
[0003] Some existing sterile incubators, especially those used in experimental environments with higher safety requirements, are equipped with isolation gloves. However, the existing isolation gloves used for sterile testing are generally kneaded into an uneven state when not in use or when worn by staff, resulting in the staff needing to frequently move their fingers to wear the gloves correctly each time, and requiring both hands to cooperate when taking off the gloves. Otherwise, due to the characteristics of rubber gloves, friction will be generated between the palm and the rubber, making it very difficult to operate, and sometimes the gloves will be turned over to the outside of the testing equipment, which will cause dust to accumulate inside the gloves, affecting hygiene.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0029] See also Figure 1-Figure 7 As shown, a sterility detection device includes a sterile culture detection box 1, and also includes: a bottom plate 2 fixed to the bottom of the sterile culture detection box 1, and a glove box 3 is arranged on one side of the sterile culture detection box 1. It should be noted that the sterile culture detection box 1 and the glove box 3 in the above description are devices with relatively mature applications in the prior art. The specific model can be selected according to actual needs and will not be repeated here. Rubber gloves 4 are arranged on both sides of the inside of the glove box 3, and a motor 5 is fixedly connected to one side of the glove box 3. By turning on the motor 5, the bidirectional screw 6 can be rotated, and the output end of the motor 5 passes through the inside of the glove box 3 and is fixedly connected to the bidirectional screw 6;
[0030] The internal thread plate 7 connected to both sides of the surface of the bidirectional screw rod 6 is rotatable. Through the setting of the internal thread plate 7, the connecting block 8 and the extension plate 9 and the support plate 10 can be driven to move relative or oppositely. One side of the internal thread plate 7 is connected to the connecting block 8 in a damping rotation manner, one side of the connecting block 8 is fixedly connected to the extension plate 9, one side of the top of the extension plate 9 is fixedly connected to the support plate 10, and the top of the extension plate 9 is fixedly connected to a pressing piece 13. The top position of the rubber glove 4 can be pressed by the pressing piece 13. The pressing piece 13 includes a hydraulic rod 1301 and a second clamping plate 1302.
[0031] A controller body 11 electrically connected to the motor 5 is fixedly connected to one side of the glove box 3. The controller body 11 is electrically connected to the motor 5 and the hydraulic rod 1301 to facilitate control and drive. One end of the bidirectional screw 6 is rotatably connected to the inner wall of the glove box 3 through a bearing. A partition 12 for limiting the maximum flipping angle of the connecting block 8 is fixedly connected to the surface of the internal threaded plate 7. By setting the partition 12, the maximum flipping position of the connecting block 8 can be limited. There are two partitions 12, which are respectively distributed and fixed on the two internal threaded plates 7. A reinforcing rib 17 is fixedly connected to one side of the connecting block 8. The fixed connection of the reinforcing rib 17 and the extension plate 9 can improve the connection strength between the connecting block 8 and the extension plate 9. One side of the reinforcing rib 17 is fixedly connected to the extension plate 9.
[0032] One side of the support plate 10 is fixedly connected to the first clamping plate 14. The first clamping plate 14 is fixed to the first rubber tooth block 15, and the first rubber tooth block 15 is distributed in an array at the bottom of the rubber glove 4, which can generate resistance when the rubber glove 4 is clamped, so that the staff can better separate the palm from the inside of the rubber glove 4. The top of the first clamping plate 14 is fixedly connected with a plurality of first rubber tooth blocks 15 in an array. The top of the first clamping plate 14 is fixedly connected with a sandwich plate 16 used to separate the rubber glove 4. Through the setting of the sandwich plate 16, the three fingers in the middle of the palm can be separated, so as to clamp and limit the rubber glove 4. The sandwich plate 16 is arranged in an array. One side of the top of the first clamping plate 14 is fixedly connected with a retaining plate 18. Slide bars 19 are arranged on the front and back sides of the retaining plate 18. A movable Plate 20, a first spring 21 is fixedly connected between one side of the retaining plate 18 and the movable plate 20. When the staff's hand is placed flat on the top of the first clamping plate 14 and pressed backward to a certain extent, the movable plate 20 will drive the sliding bar 19 to move within the internal limit of the retaining plate 18 and squeeze the first spring 21 at the same time. However, as the movable plate 20 moves, the push rod 22 will be driven to move. If the user feels that the clamping force is enough to make it easy to take off the rubber glove 4, the finger can be extended backward. At this time, the push rod 22 presses against the first pressure sensor 23, and the first pressure sensor 23 is electrically connected to the hydraulic rod 1301, which will stop the hydraulic rod 1301 from retracting, thereby facilitating the staff's fingers to detach from the rubber glove 4. A push rod 22 is fixedly connected to one side of the movable plate 20, and a first pressure sensor 23 is fixedly connected to one side of the retaining plate 18.
[0033] The hydraulic rod 1301 is fixed to the top of the extension plate 9, and the top of the hydraulic rod 1301 is fixedly connected to the limiting plate 1303, and the limiting plate 1303 is slidably connected with multiple retaining rods 1304 inside the limiting plate 1303, and the bottom of the retaining rod 1304 is fixedly connected to the second clamping plate 1302, and the second spring group 1305 is fixedly connected between the top of the retaining rod 1304 and the second clamping plate 1302, and one side of the limiting plate 1303 is slidably connected to the limiting rod 1306, and the bottom of the limiting rod 1306 is fixedly connected to the extension plate 9. First, the limiting plate 1303 is driven to descend by the retraction of the hydraulic rod 1301. At this time, the limiting plate 1303 will move in a limited position on the surface of the limiting rod 1306, and the retaining rod 1304 cooperates with the second clamping plate 1302 and the second spring group 1305 to make the second clamping plate 1302 elastically fit the rubber gloves 4 of the staff. At the top, the second rubber tooth block 1307 will fit on the surface of the rubber glove 4 to generate friction resistance between the rubber glove 4 and the second rubber tooth block 1307, and as the second clamping plate 1302 descends, the second spring group 1305 will be forced to retract, and at the same time, the second pressure sensor 1308 will press against the palm of the staff. At this time, the second pressure sensor 1308 is electrically connected to the hydraulic rod 1301, and at the same time cooperates with the first pressure sensor 23 to stop the hydraulic rod 1301 from retracting, thereby slightly clamping the rubber glove 4. At that time, the user can take off his fingers from the inside of the rubber glove 4. Similarly, it is also convenient for the staff to wear it directly next time. The bottom array of the second clamping plate 1302 is fixedly connected with a plurality of second rubber tooth blocks 1307, and one side inside the second clamping plate 1302 is fixedly connected with a second pressure sensor 1308.
[0034] Working principle: first turn on the motor 5 to cooperate with the two-way screw rod 6 to rotate. At this time, the two internal thread plates 7 will drive the connecting block 8 to move relative to each other, and the bottom of the internal thread plate 7 is fixedly connected with a sliding ring, and a sliding rod is arranged inside the sliding ring, which can limit the movement of the internal thread plate 7, and with the movement of the connecting block 8, the extension plate 9 and the support plate 10 will be driven to move relative to each other. At this time, the staff can place the palm of the hand wearing the rubber glove 4 flat on the top of the first clamping plate 14, and relax it on the top of the first clamping plate 14. At this time, the first rubber tooth block 15 on the top of the first clamping plate 14 will contact with the rubber glove 4, and at the same time, the fingers are separated by the interlayer plate 16, and then through The hydraulic rod 1301 retracts and drives the limit plate 1303 to descend. At this time, the limit plate 1303 will move within a limited position on the surface of the limit rod 1306, and the fixing rod 1304 will cooperate with the second clamping plate 1302 and the second spring group 1305 to make the second clamping plate 1302 elastically fit the top of the rubber glove 4 of the staff. At this time, the second rubber tooth block 1307 will fit the surface of the rubber glove 4 to generate friction resistance between the rubber glove 4 and the second rubber tooth block 1307, and as the second clamping plate 1302 descends, the second spring group 1305 will be forced to retract, and at the same time, the second pressure sensor 1308 will press against the palm of the staff. The pressure sensor 1308 is electrically connected to the hydraulic rod 1301, and cooperates with the first pressure sensor 23 to stop the hydraulic rod 1301 from retracting, thereby slightly clamping the rubber glove 4. At that time, the user can remove the finger from the inside of the rubber glove 4. At this time, the rubber glove 4 will be prevented from being separated from the inside of the glove box 3 by the friction of the first rubber tooth block 15 and the second rubber tooth block 1307, and the palm of the staff can be smoothly separated from the inside of the rubber glove 4. Similarly, it is also convenient for the staff to wear it directly next time. However, when wearing it, the palm can be inserted into the inside of the rubber glove 4 and the finger can be pressed against the first pressure sensor 23. Sensor 23, since the first pressure sensor 23 is electrically connected to the hydraulic rod 1301 synchronously, the hydraulic rod 1301 will drive the limit plate 1303 to rise. At this time, the limit plate 1303 will move on the surface of the limit rod 1306, and the fixing rod 1304 will cooperate with the second clamping plate 1302 and the second spring group 1305 to make the second clamping plate 1302 gradually separate from the top of the staff's rubber glove 4. Then the user can separate the palm from between the first clamping plate 14 and the second clamping plate 1302, and control the motor 5 through the controller body 11 to rotate the bidirectional screw rod 6, and move the internal thread plate 7 and the connecting block 8 to the operating area in the opposite direction.
