[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part or all of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0027] In the embodiments, by Figure 1-4 The present invention discloses a sterile isolation box for laboratory animals. The invention includes a base 1, an isolation box 2 fixedly connected to the top of the base 1, two ventilation openings inside the isolation box 2, air filters 3 on the outer side of each ventilation opening, a first door panel 4 on the front side of the interior of the isolation box 2, a second door panel 5 on the right side of the interior of the isolation box 2, an isolation frame 6 fixedly connected inside the isolation box 2, a hydraulic push rod 7 fixedly connected to the top of the isolation box 2, an isolation plate 8 extending through and into the interior of the isolation box 2 fixedly connected to the outer side of the hydraulic push rod 7, two sliding grooves inside both the isolation box 2 and the isolation frame 6, sliding plates 9 fixedly connected to the interior of each of the four sliding grooves by fasteners, connecting rods 10 fixedly connected to the outer side of each of the four sliding plates 9, and movably connected to a partition 11 on the outer side of each of the four connecting rods 10, and multiple ultraviolet sterilization lamps 16 inside both the isolation box 2 and the isolation frame 6.
[0028] The lower ventilation opening is the air inlet, and the upper ventilation opening is the air outlet. Both ventilation openings are equipped with protective mesh 12.
[0029] In this embodiment, during actual use, it helps air flow from bottom to top, forming an upward airflow, which helps to carry away the pollutants produced by the experimental animals upward and discharge them through the air outlet. This design can effectively reduce the accumulation of pollutants in the chamber and maintain a sterile environment inside the chamber. The protective mesh 12 plays a role in isolation and protection, preventing the waste produced by the experimental animals from clogging the air outlet.
[0030] The first door panel 4 and the second door panel 5 are each provided with a first observation window 13, and the isolation box 2 is provided with a second observation window 14 on the front side of the interior.
[0031] In this embodiment, during actual use, the first door panel 4 and the second door panel 5 can be opened or closed respectively, and both the first observation window 13 and the second observation window 14 can be used to observe the interior of the isolation box 2.
[0032] The cross-sections of the four slides are all convex, and the interiors of the four slide plates 9 are threaded with bolts 15 that pass through and extend into the interiors of the four slides respectively.
[0033] In this embodiment, during actual use, when the bolt 15 is loosened, the four slide plates 9 can slide freely inside the slide groove to adjust the position of each connecting rod 10. When the bolt 15 is tightened, due to the action of the thread, the slide plate 9 will move outward. A buffer rubber pad can be set on the outside of the slide plate 9. Through the friction between the rubber pad and the inside of the slide groove, the slide plate 9 is fixed under the action of the continuously tightened bolt 15.
[0034] The partition 11 has four limiting grooves inside, and the width of the four connecting rods 10 is smaller than the width of the four limiting grooves.
[0035] In this embodiment, during actual use, the size of the limiting grooves opened below the partition 11 is larger than the upper surface area of the connecting rod 10. By placing the partition 11 above the connecting rod 10, the partition 11 can be limited to increase the longitudinal activity space of the experimental animal. The partition 11 is also easy to disassemble and remove for cleaning.
[0036] The isolation box 2 has a sealing gasket fixedly connected to the outside of the isolation plate 8, and the partition plate 11 has a clearance groove inside.
[0037] In this embodiment, during actual use, the isolation plate 8 can divide the isolation box 2 into left and right parts, and the spacer slot allows the partition plate 11 to reserve the position of the ultraviolet sterilization lamp 16 when adjusting the height. When feeding experimental animals or placing objects, sterilization is carried out on both sides separately to prevent the experimental animals from being contaminated.
[0038] Working principle:
[0039] Before isolating the experimental animals, the positions of the connecting rod 10 and the partition 11 can be adjusted by loosening or loosening the bolt 15. After closing the first door 4, the ultraviolet sterilization lamp 16 inside the isolation chamber 2 should be kept on, and the air filter 3 should also be kept running. The air filter 3 consists of a fan, a high-efficiency filter, a controller, and a differential pressure sensor, which can facilitate the purification and circulation of the air inside the isolation chamber 2. Then, the experimental animals can be put into the isolation chamber 2 through the second door 5 on the right side. At this time, the isolation plate 8 is in the lowered state. After the experimental animals are sterilized by the ultraviolet sterilization lamp 16 for a period of time, the isolation plate 8 can be raised by the hydraulic push rod 7, and the experimental animals can be driven to the left side of the isolation chamber 2, which has more space, to live. Then, the isolation plate 8 is lowered. When it is necessary to feed or put items into the experimental animals, the items can be placed in the space on the right side of the isolation plate 8 first. After a period of filtration and sterilization, the isolation plate 8 can be opened. All experiments can be observed through the observation window.
