Description

Technical Field

[0001] The present application relates to the technical field of microbiological testing, and in particular to an anaerobic biological culture chamber for biological testing. Background Art

[0002] The anaerobic culture chamber is a kind of experimental equipment specially used for cultivating anaerobic microorganisms. The anaerobic biological culture chamber simulates the living conditions of anaerobic microorganisms in nature by providing a closed, oxygen-free environment, thereby supporting their growth and reproduction.

[0003] Existing anaerobic microorganisms are cultured in incubators. During the operation of the incubator, the air in the incubator needs to be pumped out and nitrogen needs to be pumped in to cultivate the anaerobic organisms. During the reproduction process, anaerobic organisms may need to be sampled to observe the culture conditions, and at this time, the door of the incubator needs to be opened; but since oxygen can easily enter the incubator when the door is opened, the incubator needs to be vacuumed and nitrogen needs to be discharged again when it is closed. The amount of nitrogen required is large and needs to be improved. Utility Model Content

[0004] In order to reduce the amount of nitrogen that needs to be refilled into the incubator after sampling the anaerobic organisms in the incubator, the present application provides an anaerobic organism culture chamber for biological testing.

[0005] The anaerobic biological culture chamber for biological testing provided in this application adopts the following technical solution:

[0006] An anaerobic biological culture chamber for biological testing comprises a box body, a partition, and a driving assembly. The box body has a culture chamber and a removal chamber, the volume of the culture chamber is smaller than the volume of the removal chamber, and the partition is used to separate the culture chamber and the removal chamber; an operating table is installed in the culture chamber, and the driving assembly is used to drive the operating table into the removal chamber.

[0007] By adopting the above technical solution, the driving component can switch the operating table back and forth between the culture chamber and the extraction chamber through the flexible separation of the partition; when anaerobic biological sampling is required, the anaerobic environment in the culture chamber will not be damaged; when the operating table in the extraction chamber is moved back to the culture chamber, since the volume of the culture chamber is larger than that of the extraction chamber, the air in the extraction chamber can be quickly extracted and the amount of nitrogen charged into the extraction chamber can be reduced.

[0008] Optionally, the driving assembly includes a thumb cylinder, which is installed in a box and is used to clamp the operating table.

[0009] By adopting the above technical solution and using the thumb cylinder to clamp the operating table, the operating table can be driven to move within the box, so as to achieve rapid switching of the operating table between the extraction chamber and the culture chamber.

[0010] Optionally, a first slide rail is provided in the culture chamber, a second slide rail is provided in the removal chamber, and the operating table is slidably installed on the first slide rail through a sliding seat; the distance between the first slide rail and the second slide rail is smaller than the length of the sliding seat, and the driving assembly is used to drive the sliding seat from the first slide rail into the second slide rail.

[0011] By adopting the above-mentioned technical solution, by setting the first slide rail and the second slide rail, the stability of the operating table sliding in the removal chamber and the culture chamber can be increased; and the distance between the first slide rail and the second slide rail is smaller than the length of the sliding seat, so that when the sliding seat enters from the first slide rail to the second slide rail, the operating table will not be detached or stuck.

[0012] Optionally, the sliding seat is provided with a telescopic slot, in which a telescopic rod is movably installed; a first spring is arranged between the telescopic rod and the inner wall of the telescopic slot, and the elastic force of the first spring is used to drive the telescopic rod to move toward a side away from the telescopic slot, and the first slide rail and the second slide rail are both provided with a clamping slot for inserting the telescopic steel rod.

[0013] By adopting the above technical solution, when the operating table stops moving on the first slide rail / the second slide rail, the driving component is used to drive the telescopic groove and the clamping groove to be arranged opposite each other, and the elastic force of the first spring drives the telescopic rod to be inserted into the telescopic groove, so that the position of the operating table on the box body can be fixed; the possibility of free movement of the operating table due to external vibration is reduced, and the possibility of anaerobic organisms in the operating table being spread to the outside of the operating table is reduced.

[0014] Optionally, a hemispherical head is integrally formed at one end of the telescopic rod away from the telescopic slot, and the hemispherical head is inserted into the clamping slot.

[0015] By adopting the above-mentioned technical solution, the outer wall of the hemispherical head can guide the telescopic rod into the telescopic groove. When the driving component drives the first slide rail / second slide rail of the operating table to move, the hemispherical head abuts against the inner wall of the clamping groove, thereby driving the hemispherical head into the telescopic groove, so that the operating table slides on the first slide rail / second slide rail.

[0016] Optionally, both the first slide rail and the second slide rail are provided with rubber damping.

[0017] By adopting the above technical solution and setting rubber damping, the friction between the sliding seat and the sliding seat can be increased, thereby further reducing the possibility of free movement of the operating table due to external vibration and reducing the possibility of anaerobic organisms in the operating table spreading to the outside of the operating table.

[0018] Optionally, the driving assembly includes a connecting piece, a motor and two screw rods, the two screw rods are rotatably installed in the culture chamber and the rotating chamber respectively, and the connecting piece is used to connect the two screw rods; the sliding seat is provided with a rotating groove, and the screw rod is rotatably connected to the rotating groove; the motor is installed in the box and connected to one of the screw rods.

[0019] By adopting the above technical solution, when the operating table needs to be switched from the culture chamber to the extraction chamber, the connecting piece is used to drive the two screws to connect; then the motor is driven to rotate, and the two screws rotate at the same time; when the screw rotates, the sliding seat moves along the direction of the screw under the rotation connection between the rotating groove and the screw, thereby playing the role of switching the operating table back and forth between the culture chamber and the extraction chamber.

[0020] Optionally, a sealing groove for inserting a partition plate is provided on the inner wall of the box body, and a first rubber layer is provided on the outer wall of the partition plate.

[0021] By adopting the above technical solution, the partition plate is inserted into the sealing groove by interference fit, which can increase the sealing of the extraction chamber and the culture chamber and reduce the situation where external oxygen enters the culture chamber when the operating table is transferred to the extraction chamber for sampling.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. By setting up the extraction chamber and the culture chamber, the driving component can switch the operating table back and forth between the culture chamber and the extraction chamber; when anaerobic biological sampling is required, the anaerobic environment in the culture chamber will not be damaged; when the operating table in the extraction chamber is moved back to the culture chamber, since the volume of the culture chamber is larger than that of the extraction chamber, the air in the extraction chamber can be quickly extracted and the amount of nitrogen charged into the extraction chamber can be reduced;

[0024] 2. By setting the rubber damping, the friction between the sliding seat and the sliding seat can be increased, further reducing the possibility of the operating table moving freely due to external vibration, and reducing the possibility of anaerobic organisms in the operating table spreading to the outside of the operating table.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-5 This application is described in further detail.

[0032] Embodiment 1:

[0034] Reference Figure 1 and Figure 2 An anaerobic biological culture chamber for biological testing includes a box body 1, a drive assembly 2 and a partition 3. The box body 1 has a culture chamber 11 and a removal chamber 12. The volume of the culture chamber 11 is smaller than that of the removal chamber 12. The culture chamber 11 is used to culture anaerobic organisms, and the removal chamber 12 is used to sample anaerobic organisms. The partition 3 is used to separate the culture chamber 11 and the removal chamber 12.

[0035] Reference Figure 2 The outer wall of the partition 3 is wrapped with a first rubber layer 31, and sliding grooves 13 are provided on the opposite side walls of the culture chamber 11. The two ends of the partition 3 are respectively slidably installed in the sliding grooves 13, and one side of the partition 3 is in contact with the inner wall of the culture chamber 11 close to the removal chamber 12; a sealing groove 14 is provided on the bottom wall of the culture chamber 11, and the two ends of the sealing groove 14 are respectively connected with the sliding grooves 13 on the opposite sides of the culture chamber 11; a first cylinder 15 is fixed to the box body 1, and the movable plug of the first cylinder 15 is fixed to the partition 3.

[0036] By driving the first cylinder 15, one side of the partition 3 can be inserted into the sealing groove 14 to separate the extraction chamber 12 and the culture chamber 11; and the provision of the first rubber layer 31 can increase the sealing performance of the partition 3 inserted into the sealing groove 14, thereby reducing the situation where external air enters the culture chamber 11 when the sampling chamber is sampling anaerobic organisms.

[0037] A first slide rail 16 is provided on the inner bottom wall of the culture chamber 11, and a second slide rail 17 is provided on the inner bottom wall of the removal chamber 12, and the first slide rail 16 and the second slide rail 17 are arranged opposite to each other; both the first slide rail 16 and the second slide rail 17 are provided with rubber damping 5; a sliding seat 41 is installed on the surface of the first slide rail 16 for sliding movement, and the width of the sliding seat 41 is greater than the distance between the first slide rail 16 and the second slide rail 17; the driving component 2 is used to drive the sliding seat 41 to switch from the first slide rail 16 to the second slide rail 17.

[0038] An operating table 4 is arranged above the sliding seat 41, and the operating table 4 is used to place a culture dish for culturing organisms; the driving component 2 includes a thumb cylinder 21, and the thumb cylinder 21 is installed on the box body 1, and the moving direction of the piston rod of the thumb cylinder 21 is the same as the extension direction of the first slide rail 16; in this embodiment, a clamping portion 42 for clamping the thumb cylinder 21 is integrally formed on one side of the operating table 4 close to the culture chamber 11.

[0039] By clamping the clamping portion 42 through the thumb cylinder 21, the sliding seat 41 can be driven to move on the first slide rail 16 and enter the second slide rail 17, so as to increase the stability of the operating table 4 moving back and forth in the culture chamber 11 and the removal chamber 12; and the distance between the first slide rail 16 and the second slide rail 17 is smaller than the length of the sliding seat 41, so as to prevent the operating table 4 from being detached or stuck during the process of the sliding seat 41 entering from the first slide rail 16 to the second slide rail 17.

[0040] In addition, when the sliding seat 41 stops moving on the first slide rail 16 / the second slide rail 17, in order to avoid energy loss caused by long-term activation of the thumb cylinder 21, the thumb cylinder 21 cancels the contact with the clamping portion 42; the rubber damper 5 can increase the friction between the sliding seat 41 and the first slide rail 16 / the second slide rail 17, increase the stability of the operating table 4 in the box body 1, reduce the possibility of free movement of the operating table 4 due to external vibration, and reduce the possibility of anaerobic organisms in the operating table 4 spreading to the outside of the operating table 4.

[0041] The implementation principle of Example 1 of the present application is:

[0042] Through the flexible separation of the partition 3, the thumb cylinder 21 can switch the operating table 4 back and forth between the culture chamber 11 and the extraction chamber 12; when anaerobic biological sampling is required, the anaerobic environment in the culture chamber 11 will not be damaged; when the operating table 4 in the extraction chamber 12 is moved back to the culture chamber 11, since the volume of the culture chamber 11 is larger than the volume of the extraction chamber 12, the air in the extraction chamber 12 can be quickly extracted and the amount of nitrogen charged into the extraction chamber 12 can be reduced.

[0043] Embodiment 2:

[0046] The implementation principle of Example 2 of the present application is:

[0047] When the operating table 4 is stably parked in the culture chamber 11 / removal chamber 12, the thumb cylinder 21 is driven to set the telescopic groove 43 and the snap-in groove 18 opposite each other, so that the hemispherical head 61 is inserted into the snap-in groove 18 under the elastic force of the first spring 62, which can reduce the free sliding of the sliding seat 41 on the first slide rail 16 / second slide rail 17; thereby reducing the possibility of free movement of the operating table 4 due to external vibration.

[0048] When it is necessary to switch the operating table 4 back and forth between the culture chamber 11 and the removal chamber 12, the outer wall of the hemispherical head 61 abuts against the inner wall of the snap-in groove 18 to guide the telescopic rod 6 into the telescopic groove 43, so as to cancel the fixation between the operating table 4 and the first slide rail 16 / the second slide rail 17, so that the sliding seat 41 can slide smoothly on the first slide rail 16 and the second slide rail 17.

[0049] Embodiment 3:

[0050] The embodiment of the present application discloses an anaerobic biological culture chamber for biological testing.

The second cylinder 25 is rotatably installed on the box body 1 and connected to the plug-in rod 26; the screw rod 22 located in the culture chamber 11 is provided with a plug-in groove 27 for the plug-in rod 26 to be plugged in. Inserting the plug-in rod 26 in the plug-in groove 27 can connect the two screw rods 22 to drive them to rotate simultaneously.

[0053] In this embodiment, a second rubber layer is provided between the second cylinder 25 and the housing 1 , which can increase the friction between the second cylinder 25 and the housing 1 to reduce the free rotation of the second cylinder 25 and further reduce the free rotation of the screw rod 22 in the extraction chamber 12 .

[0054] The implementation principle of Example 3 of the present application is:

[0055] When it is necessary to switch the operating table 4 from the culture chamber 11 to the extraction chamber 12, the second cylinder 25 is driven to insert the plug-in rod 26 into the plug-in groove 27; then the motor 23 is driven to rotate, and the two screw rods 22 rotate at the same time; when the screw rod 22 rotates, the sliding seat 41 moves along the direction of the screw rod 22 under the rotation connection between the rotating groove and the screw rod 22, thereby playing the role of switching the operating table 4 back and forth in the culture chamber 11 and the extraction chamber 12.
