Description

[0002] The detection of whether biological samples contain microorganisms has a wide range of uses in clinical diagnosis and biomedical research, and the detection methods and processes are relatively demanding. On the one hand, due to the special requirements of the living environment of microorganisms, it is required to promote the growth of microorganisms in a relatively constant and suitable temperature environment; on the other hand, the growth activities of microorganisms are relatively slow relative to the requirements of detection, and continuous observation for a long time is required. If artificial cultivation and detection are used, the stability of temperature and the continuity of detection cannot be guaranteed, nor can the timely and effective detection of microorganisms be guaranteed, which often delays the best time for treatment in clinical applications. In existing microbial incubation devices, functional modules such as incubation modules, temperature control modules and detection modules are generally installed directly in the box.

[0023] The beneficial effects of the present invention are:

[0024] The assembled microorganism incubation unit of the present invention is provided with an incubation cabinet, and a drawer bracket is provided in the incubation cabinet, and a module installation area is formed between the drawer back plate, the front drawer end plate and the rear drawer end plate of the drawer bracket, so that the incubation module can be directly installed on the installation station in the module installation area. In this way, the assembled microorganism incubation unit of the present invention is integrated into a whole, and can be directly installed in the box when used, which is not only convenient to install but also can improve space utilization; by arranging two groups of heat circulation fans on the drawer back plate, one group of heat circulation fans blows hot air to the module installation area, and the other group of heat circulation fans sucks air from the module installation area, so as to realize air circulation in the module installation area and improve the temperature consistency in the module installation area.

[0025] Other technical effects of the assembled microorganism incubation unit of the present invention are as follows:

[0026] 1) By setting three slide rails between the drawer bracket and the incubation cabinet, the bottom slide rails set between the two sides of the bottom of the drawer bracket and the incubation cabinet mainly bear the weight of the drawer bracket and the incubation module installed in the drawer bracket, and the top slide rails set between the top of the drawer bracket and the incubation cabinet are used to improve the stability of the drawer when sliding;

[0027] 2) By making the incubator cabinet out of aluminum or copper, which have excellent thermal conductivity, a heating film and insulation cotton can be provided only on one side wall of the incubator cabinet, so that the temperature consistency of the incubator cabinet is better;

[0028] 3) By setting a shaking drive mechanism to drive the incubation module to shake, bacteria and other microorganisms can grow faster; by using the shaking connecting rod assemblies respectively arranged on the front drawer end plate and the rear drawer end plate, all the incubation modules arranged in the module installation area can be shaken synchronously; by installing the drive motor in the control area, the heat generated by the drive motor during operation can be prevented from affecting the temperature in the incubation cabinet, thereby preventing the temperature in the incubation cabinet from exceeding the rated value;

[0029] Since the drive motor is installed in the control area, and the drawer bracket and the incubation cabinet are slidably matched, that is, the drive motor cannot move synchronously with the drawer bracket, by setting a clutch mechanism, when the drawer bracket slides out of the opening of the incubation cabinet, the clutch mechanism is separated, and the incubation module stops shaking at this time; when the drawer bracket slides into the incubation cabinet, the clutch mechanism is engaged, and the drive motor can drive the incubation module to shake;

[0030] 4) The first clutch columns are evenly distributed in an annular pattern on the first clutch disc, and the second clutch columns are evenly distributed in an annular pattern on the second clutch disc, so that the distance between the axis of the first clutch column and the axis of the transition shaft is greater than the distance between the axis of the second clutch column and the axis of the transition shaft, that is, the inner diameter of the distribution circle of the first clutch column is greater than the inner diameter of the distribution circle of the second clutch column, so that when the clutch is engaged, the first clutch column is tangent to the two adjacent second clutch columns, and similarly, the second clutch column is also tangent to the two adjacent first clutch columns, so as to realize power transmission;

[0031] By respectively arranging the first diameter-reduced section and the second diameter-reduced section on the top of the first clutch column and the second clutch column, when the clutch is engaged, it can avoid being stuck, and it can also avoid collision between the tops of the clutch columns, so that the clutch mechanism can be engaged smoothly, thereby improving the reliability of the clutch mechanism;

[0032] By providing a first through hole on the first clutch disc to give way to the second clutch column, and providing a second through hole on the second clutch disc to give way to the first clutch column, the problem of overshoot and collision caused by the clutch mechanism during the meshing process can be avoided;

[0033] 5) By setting a first magnetic element on the end plate of the rear drawer and setting an adsorption component that cooperates with the first magnetic element in the incubation cabinet, the drawer bracket can be locked and fixed in the incubation cabinet by utilizing the magnetic force between the first magnetic element and the second magnetic element.

[0034] 6) By setting up an in-place detection component, and setting an optocoupler top block that is slidably mounted on the optical axis in the detection base, the optocoupler top block is reset by a reset spring, so that the optocoupler baffle is located outside the optocoupler detection point; when the drawer bracket slides into the incubation cabinet and is in place, the rear side wall of the incubation cabinet or the rear side wall of the box body drives the optocoupler top block to overcome the elastic force of the reset spring and move forward, so that the optocoupler baffle is located at the optocoupler detection point, which can not only realize the position detection of the drawer bracket, but also avoid the problem that the optocoupler baffle and the optocoupler detection point cannot be accurately aligned due to the shaking of the drawer bracket during the sliding process, thereby improving the detection reliability; BRIEF DESCRIPTION OF THE DRAWINGS

At least one incubation cabinet 31 is installed in the culture area. When the number of incubation cabinets 31 is set to at least two, all the incubation cabinets 31 are arranged in parallel. In this embodiment, two incubation cabinets 31 are installed in parallel in the culture area.

[0057] Further, if Figure 5-6 As shown, bottom slide rails 36 are respectively provided between the two sides of the bottom of the drawer bracket and the inner walls of the two sides of the incubation cabinet 31, and a top slide rail 37 is provided between the top surface of the drawer bracket and the top surface of the incubation cabinet 31. By arranging three slide rails between the drawer bracket and the incubation cabinet 31, the bottom slide rails 36 arranged between the two sides of the bottom of the drawer bracket and the incubation cabinet 31 mainly bear the weight of the drawer bracket and the incubation module 10 installed in the drawer bracket, and the top slide rail 37 arranged between the top of the drawer bracket and the incubation cabinet 31 is used to improve the stability of the drawer when sliding.

The incubation cabinet 31 of this embodiment is made of aluminum.

[0059] Further, a drawer door handle 40 is provided on the drawer bracket, and a handle display screen 41 is installed on the drawer door handle 40.

Specifically, since three incubation modules are installed in the drawer bracket of the present embodiment, three support rods 62 are connected to each linkage rod 61, and the support rods 62 are embedded in the brackets 13. When the support rods 62 swing, the incubation modules 10 are driven to rock accordingly. Figure 8As shown, the shaking drive assembly of this embodiment includes a swing rod 63, the middle part of the swing rod 63 is rotatably matched with a rotating shaft 64 set on the rear drawer end plate 34, one end of the swing rod 63 is hingedly connected to the linkage rod 61, and the other end is provided with a shaking power assembly for driving it to reciprocate around the rotating shaft 64 within a set angle range. Preferably, a detection optical coupler 65 for detecting the swing position of the swing rod 63 is provided on the rear drawer end plate 34 of this embodiment. The detection optical coupler 65 is used to detect the movement working condition of the drawer bracket, and is also used to control the state of the incubation module 10 when the drawer bracket is pulled out. During use, the incubation module 10 shakes within the range of 20° horizontally and upwards. The position of the detection optical coupler 65 is fixed. When the host computer receives the operation instruction to pull out the drawer bracket, the detection optical coupler 65 can determine the current position of the drawer bracket, and stop the incubation module at a position of 20° upwards through the shaking power assembly, and then release the electromagnet that locks the drawer bracket to ensure that the incubation module 10 is at an angle that is convenient for plugging and unplugging the culture bottle 22 when the drawer bracket is pulled out. Specifically, in this embodiment, two detection photocouplers 65 are provided, which are used to detect whether the incubation module 10 is in the horizontal position and the upward position of 20° respectively.

[0064] Specifically, the driving power assembly of the present embodiment includes a driving rod 66, an eccentric shaft 67 and a driving assembly for driving the eccentric shaft 67 to rotate, the two ends of the driving rod 66 are respectively hingedly connected to the swing rod 63 and the eccentric shaft 67, and the driving assembly includes a driving motor 68, and the driving motor 68 is connected to the eccentric shaft 67 by transmission. Specifically, a transition shaft 69 is provided on the rear drawer end plate 34 of the present embodiment; the output shaft of the driving motor 68 is connected to the transition shaft 69 by transmission, and the transition shaft 69 is connected to the eccentric shaft 67 by transmission. The driving motor 68 of the present embodiment is installed in the control area, and a clutch mechanism is provided on the transition shaft 69. Specifically, a motor seat 86 is provided on the top surface of the incubation cabinet 31, and the motor seat extends into the control area, and the driving motor 68 is installed on the motor seat and is located in the control area. Of course, in some other embodiments, the driving motor 68 can be directly installed on the rear drawer end plate 34, and the output shaft of the driving motor 68 is directly connected to the eccentric shaft 67 by transmission, and no more description is repeated. A first synchronous belt mechanism is provided between the output shaft of the driving motor 68 of this embodiment and the transition shaft 69, and the first synchronous belt mechanism includes a first synchronous pulley 70 provided on the output shaft of the driving motor 68 and a second synchronous pulley 71 provided on the transition shaft 69, and a first synchronous belt 72 is provided between the first synchronous pulley 70 and the second synchronous pulley 71. A second synchronous belt mechanism is provided between the transition shaft 69 and the eccentric shaft 67, and the second synchronous belt mechanism includes a third synchronous pulley 73 provided on the transition shaft 69 and a fourth synchronous pulley 74 provided on the eccentric shaft 67, and a second synchronous belt 75 is provided between the third synchronous pulley 73 and the fourth synchronous pulley 74, and a clutch mechanism is located between the second synchronous pulley 71 and the third synchronous pulley 73. By setting up a shaking drive mechanism to drive the incubation module to shake, bacteria and other microorganisms can grow faster; by using the shaking connecting rod assemblies respectively arranged on the front drawer end plate and the rear drawer end plate, all incubation modules arranged in the module installation area can be shaken synchronously; by installing the drive motor 68 in the control area, the heat generated by the drive motor 68 during operation can be prevented from affecting the temperature in the incubation cabinet 31, thereby preventing the temperature in the incubation cabinet 31 from exceeding the rated value.

[0065] Since the drive motor 68 is installed in the control area, and the drawer bracket and the incubation cabinet 31 are slidably matched, that is, the drive motor 68 cannot move synchronously with the drawer bracket. By setting a clutch mechanism, when the drawer bracket slides out of the opening of the incubation cabinet, the clutch mechanism is separated, and the incubation module stops shaking at this time; when the drawer bracket slides into the incubation cabinet, the clutch mechanism is engaged, and the drive motor can drive the incubation module to shake. Specifically, Figure 10-11As shown, the clutch mechanism of this embodiment divides the transition shaft 69 into two sections, and the two sections of the transition shaft 69 are provided with a first clutch seat 76 and a second clutch seat 77 which are respectively slidably matched and synchronously rotated therewith, and the first clutch seat 76 and the second clutch seat 77 are respectively provided with a coaxially arranged first clutch disk 78 and a second clutch disk 79 on the side facing each other, and the first clutch disk 78 is evenly distributed with first clutch columns 80 in an annular shape, and the second clutch disk 79 is evenly distributed with second clutch columns 81 in an annular shape, and the number of the first clutch columns 80 and the second clutch columns 81 is equal, and the distance between the axis of the first clutch column 80 and the axis of the transition shaft 69 is greater than the distance between the axis of the second clutch column 81 and the axis of the transition shaft 69; when the clutch mechanism is in the engaged state, the first clutch column 80 is tangent to the two adjacent second clutch columns 81. By evenly distributing the first clutch posts 80 in a circular shape on the first clutch disc 78 and evenly distributing the second clutch posts 81 in a circular shape on the second clutch disc 79, the distance between the axis of the first clutch post and the axis of the transition shaft is greater than the distance between the axis of the second clutch post and the axis of the transition shaft, that is, the inner diameter of the distribution circle of the first clutch post is greater than the inner diameter of the distribution circle of the second clutch post, so that when the clutch is engaged, the first clutch post is tangent to the two adjacent second clutch posts, and similarly, the second clutch post is also tangent to the two adjacent first clutch posts, thereby realizing power transmission.

[0066] Preferably, the top of the first clutch column 80 of the present embodiment is provided with a first diameter-reducing section 82, and the outer diameter of the first diameter-reducing section 82 gradually decreases along the direction from the first clutch disc 78 to the second clutch disc 79; the top of the second clutch column 81 is provided with a second diameter-reducing section 83, and the outer diameter of the second diameter-reducing section 83 gradually decreases along the direction from the second clutch disc 79 to the first clutch disc 78. The first diameter-reducing section 82 and the second diameter-reducing section 83 of the present embodiment are both conical. By respectively providing the first diameter-reducing section and the second diameter-reducing section at the top of the first clutch column and the second clutch column, when the clutch is engaged, it can avoid getting stuck, and it can also avoid collision between the tops of the clutch columns, so that the clutch mechanism can be smoothly engaged, and the reliability of the clutch mechanism is improved.

[0067] Preferably, the first clutch disc 78 is provided with a first through hole 84 for giving way to the second clutch column 81, and the second clutch disc 79 is provided with a second through hole 85 for giving way to the first clutch column 80. By providing the first through hole for giving way to the second clutch column on the first clutch disc and the second through hole for giving way to the first clutch column on the second clutch disc, the problem of collision caused by overshoot during the engagement process of the clutch mechanism can be avoided.

[0068] Further, if Fig.12As shown, the incubation module 10 includes an incubation module bracket 14 and an incubation bottle holder 15 fixedly mounted on the incubation module bracket 14, and the culture bottle sockets 11 are arranged in the incubation bottle holder 15. Specifically, one or two rows of culture bottle sockets 11 are arrayed in the incubation bottle holder 15, and heating films 16 and heating film pressing plates 17 are respectively arranged on both sides of the one or two rows of culture bottle sockets. By arranging one or two rows of culture bottle sockets 11 in the incubation bottle holder 15, and arranging heating films 16 and heating film pressing plates 17 on both sides of the culture bottle sockets 11, the temperature of all culture bottle sockets 11 can be made more uniform. The incubation bottle holder 15 of this embodiment is arrayed with two rows of culture bottle sockets 11.

[0069] Preferably, the incubation bottle seat 15 is made of aluminum or copper. By making the incubation bottle seat of aluminum or copper, the good thermal conductivity of aluminum and copper can be used to make the incubation bottle seat have good temperature uniformity and stability; at the same time, after the drawer bracket is pulled out from the opening of the incubation cabinet, the incubation bottle seat will cause temperature changes at ambient temperature, and the drawer bracket returns to the control temperature after being pushed into the incubation cabinet, that is, there is temperature fluctuation in the process of pulling out and pushing in the drawer bracket. The incubation bottle seat made of aluminum or copper has a large specific heat capacity and thermal conductivity, thereby reducing the amplitude of temperature fluctuation.

[0070] Furthermore, a spring piece 18 for clamping the culture bottle 12 is provided in the culture bottle insertion hole 11 . The spring piece 18 is made of spring steel and can clamp and fix the culture bottle 12 in the culture bottle insertion hole 11 .

[0071] Furthermore, a detection component for detecting the growth of microorganisms is provided below the culture bottle socket 11. The detection component of this embodiment includes an optical signal detector 19 and a signal light source 20. A light-transmitting hole 21 is provided at the bottom of the culture bottle socket 11. The optical signal emitted by the signal light source 20 is irradiated on the bottom surface of the culture bottle 12 installed in the culture bottle socket 11 through the light-transmitting hole 21, and the optical signal reflected by the culture bottle 12 is transmitted to the signal detector 19 through the light-transmitting hole 21. Specifically, the detection principle of the detection component is: bacteria and other microorganisms metabolize to produce carbon dioxide, and an ion exchange membrane and a color-developing substance are provided at the bottom of the culture bottle 12. After carbon dioxide is produced, the bottom of the bottle will gradually change color, and the more carbon dioxide is produced, the more obvious the color will be. Detection 2, the signal light source 20 periodically generates an optical signal, the optical signal is irradiated to the bottom of the bottle, and then the reflected light is captured by the optical signal detector 19, and the growth of microorganisms such as bacteria is judged according to the intensity and intensity change trend of the optical signal of a fixed wavelength.

[0072] Furthermore, the light signal emitted by the signal light source 20 is irradiated on the smooth annular area at the bottom of the corresponding culture bottle 12. Since the center position of the bottom of the culture bottle is the glue feeding position, the surface at this position is extremely uneven. In the prior art, the light signal emitted by the signal light source is often directly irradiated on the center position of the bottom of the culture bottle. When the culture bottle rotates, it will cause a large fluctuation in the detection signal. By irradiating the light signal emitted by the signal light source on the smooth annular area at the bottom of the culture bottle, when the culture bottle rotates, it will not cause too much impact on the detection signal, thereby improving the detection accuracy.

[0073] In the light-transmitting hole 21 of the present embodiment, a dustproof light-transmitting plate 22 is provided, and a portion of the light signal emitted by the signal light source 20 is reflected by the dustproof light-transmitting plate 22 to form a reflection irradiation area, and the signal detector 19 is located outside the reflection irradiation area. By arranging the signal detector outside the reflection irradiation area after the light signal is reflected by the dustproof light-transmitting plate, the problem of high background noise due to the reflected light signal entering the signal detector can be avoided, that is, the background noise can be effectively reduced.

[0074] A light shielding bowl 23 is also provided below the culture bottle socket 11 of this embodiment to prevent interference of light signals from adjacent detection components. A front cover plate 24 is installed on the incubation module 10 of this embodiment. A through hole 28 for the culture bottle 12 to pass through is provided on the front cover plate 24 in a one-to-one correspondence with the culture bottle socket 11. A lower computer 25 is provided on the side of the optical signal detector 19 facing away from the culture bottle socket 11. The lower computer 25 is used to control the signal light source 20 to excite the light signal and transmit the light signal collected by the optical signal detector 19 to the detection system located in the control area. A detection module cover plate 26 is provided below the incubation module bracket 14. A flexible pad 27 is provided between the detection module cover plate 26 and the lower computer 25. The flexible pad 27 of this embodiment is a foam pad.

Equivalent substitutions or changes made by those skilled in the art based on the present invention are within the protection scope of the present invention. The protection scope of the present invention shall be subject to the claims.
