Description

Technical Field

[0001] The utility model belongs to the field of sterile medicine production equipment, in particular to a non-interference culture dish automatic opening and covering fully sealed dish changing device. Background Art

[0002] The production of sterile drugs must meet the requirements of their quality and intended use, and should minimize contamination by microorganisms, various particles and heat sources.

[0003] However, at present, the detection of microorganisms, especially sedimentation bacteria, is mainly achieved manually. The operator needs to open the lid of the sedimentation dish and expose it to the air for no more than 4 hours, observe and detect the flora in the sedimentation dish, and then open the next sedimentation dish for exposure for no more than 4 hours to achieve continuous dynamic detection of the environment. In the actual operation process, the opening and closing process of the lid of the sedimentation dish is manually implemented, and the time control is difficult to be accurate. The operator is prone to forget the exposure time of the sedimentation dish, resulting in inaccurate monitoring results. In addition, due to the manual process, it is inevitable that there will be contact actions, and the flora of the previous sedimentation dish will be carried to the operator, so that the flora will be brought into the next sedimentation dish. The disinfection and sterilization process is relatively cumbersome when personnel enter and leave the production area, and it is also easy to bring pollution risks to the drug production process.

[0004] Therefore, an interference-free culture dish automatic opening and covering dish changing system device used in the sterile drug production area can not only reduce the pollution caused by manual operation, but also liberate labor and improve the accuracy of the tested samples, which will greatly help the production of sterile drugs.

[0034] The feeding guide cylinder 12 and the collecting guide cylinder 13 are semi-cylindrical, and the side wall opening of the semi-cylindrical shape faces the outside of the housing 6. A detachable safety protection cover 4 is provided at the side wall opening. A lifting tray 18 for placing the culture dish 2 is provided inside the feeding guide cylinder 12 and the collecting guide cylinder 13; a lifting mechanism for driving the lifting tray 18 to move up and down is provided on the bottom plate 11 of the housing 6.

Figures 2 to 4 As shown, the opening and closing cover rotating track assembly 1 includes a long arc track 1-1 in the front, a short arc track 1-2 in the rear and an arc track cover plate 1-3 above; trapezoidal beams are provided on the two opposite arc walls of the long arc track 1-1 and the short arc track 1-2.

[0036] like Figure 7 As shown, a rotating motor 7 is provided inside the housing 6 at a position close to the short arc track 1-2 and at the symmetrical center of the two guide cylinders. Figures 5-6 As shown, the upper surface of the top plate 9 is provided with a culture dish claw assembly 3 connected to the output end of the rotating motor 7; the culture dish claw assembly 3 is provided with a circular ring claw 3-1 that cooperates with the culture dish 2, and the claw 3-1 is used to push the culture dish 2 to move horizontally in an arc shape between the feeding guide cylinder 12 and the collecting guide cylinder 13 under the drive of the rotating motor 7; the claw 3-1 is provided with a baffle 3-2 on the side close to the feeding guide cylinder 12, the height of the baffle 3-2 is greater than the trapezoidal beam and less than the circular arc track cover 1-3, and the inner diameter of the claw 3-1 is greater than the diameter of the culture dish 2.

[0037] In the utility model, a gap is provided between the lower end of the short arc track 1-2 and the top plate 9 for the culture dish claw assembly 3 to pass through when it moves horizontally; the lower end of the long arc track 1-1 is fixed on the top plate 9, and the upper end of the long arc track 1-1 and the upper end of the short arc track 1-2 are fixed to the arc track cover 1-3, that is, the short arc track 1-2 is not fixed to the top plate 9, but is fixed by the long arc track 1-1.

[0038] There are two lifting mechanisms, which are used to lift the lifting tray 18 in the feeding guide cylinder 12 and the collecting guide cylinder 13 respectively. Fig.10 As shown, the lifting mechanism includes a lifting screw motor 15 vertically fixed on the base plate 11, and a lifting upper origin sensor 15-2 and a lifting lower origin sensor 15-1 are respectively provided at the upper and lower ends of the lifting screw motor 15.

[0039] like Figures 8-9 As shown, a lithium battery 14, a motor driver 16, and an electric control board 17 are arranged inside the housing 6. Figure 1 As shown, an operation button 5 is provided on the top plate 9. The operation button 5 is connected to the electric control board 17, and the electric control board 17 receives the instruction of the operation button 5 and sends it to the motor driver 16, and controls the movement of the jacking mechanism and the rotating motor 7 through the motor driver 16.

[0040] like Fig.11 As shown, the culture dish 2 includes a culture dish plate 2-1 and a culture dish cover 2-2.

[0041] In the present invention, the area where the feeding guide cylinder 12 is located is the inoculation area, and the area corresponding to the collecting guide cylinder 13 is the recovery area. The working steps of this embodiment are described below in conjunction with the accompanying drawings:

[0042] (1) Place a plurality of culture dishes 2 to be inoculated in the lifting tray 18 of the loading guide cylinder 12 .

[0043] (2) Turn on the power switch, and the user sets the number of culture dishes 2 and the time to be inoculated according to the actual situation.

[0044] (3) Press the operation button 5, the motor driver 16 drives the lifting screw motor 15 corresponding to the feeding guide cylinder 12, so that the lifting tray 18 moves upward, and the single lifting height is the height of a culture dish.

[0045] (4) When the bottom of the culture dish 2 is flush with the top plate 9, the rotary motor 7 is started to drive the culture dish claw assembly 3 to rotate horizontally. The claw 3-1 is looped on the culture dish plate 2-1 and pushes the culture dish plate 2-1 to rotate in an arc toward the recovery area. Under the action of the baffle 3-2, the culture dish cover 2-2 can pass through the trapezoidal beam together with the culture dish plate 2-1 to reach the recovery area.

[0046] (5) After reaching the recovery area, the rotary motor 7 reverses, and the claw 3-1 pushes the culture dish plate 2-1 to rotate in an arc toward the inoculation area; due to the absence of the baffle 3-2, the culture dish cover 2-2 gradually separates from the culture dish plate 2-1 when passing through the trapezoidal beam and is placed on the trapezoidal beam.

[0047] (6) After the cover is separated, the culture dish 2-1 without the cover is further transported to the inoculation area, and inoculation begins at the set time.

[0048] (7) After the inoculation is completed, the claw 3-1 pushes the inoculated culture dish 2-1 to move along the arc to the recovery area, reaches the trapezoidal beam and begins to pass through the cover. When the front end of the culture dish 2-1 contacts the front end of the culture dish cover 2-2, the baffle 3-2 pushes the culture dish cover 2-2 to move together, and the culture dish cover 2-2 gradually descends on the trapezoidal beam until it is completely lowered onto the culture dish 2-1, completing the covering.

[0049] (8) When the culture dish 2 is pushed to the upper end of the recovery area, the bottom of the culture dish 2 contacts the lifting tray in the collection guide cylinder 13, and the lifting screw motor starts to descend one unit. At this time, the top of the culture dish 2 is flush with the top plate, and one inoculation is completed.

[0050] (9) According to the program, steps (3)-(7) are automatically cycled until all culture dishes 2 are operated and the program ends.

[0051] The embodiments described above provide a detailed description of the technical solutions and beneficial effects of the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, supplements and equivalent substitutions made within the scope of the principles of the present invention should be included in the protection scope of the present invention.
