Description

Technical Field

[0001] This utility model belongs to the field of blood culture technology, specifically relating to a fully automated blood culture instrument. Background Technology

[0002] Clinical microbiology testing is a crucial component of laboratory medicine. Its primary task is to rapidly and accurately isolate and identify various pathogenic bacteria present in a patient's body, and based on drug sensitivity results, provide accurate diagnosis and treatment. Clinical microbiology testing not only provides diagnostic evidence for infectious diseases but also informs medication use, serving as a major means of controlling antibiotic overuse and nosocomial infections, and thus possesses extremely important clinical significance and value. Bacteremia and sepsis both clinically present as acute infections with short onset times, rapid progression, severe symptoms, and serious complications. Failure to receive timely diagnosis and treatment can easily lead to missed opportunities for optimal treatment and serious consequences. Based on the clinical manifestations of bacteremia and sepsis, rapid diagnosis is a vital step in improving treatment effectiveness. Therefore, blood culture, as a diagnostic method, is crucial in providing patients with rapid and accurate blood culture results. The fully automated blood culture system plays a fundamental and core role in clinical microbiology testing, used to quickly determine whether a suspected infected patient has a bacterial infection and to preliminarily determine the type of infecting bacteria (aerobic or anaerobic). It is of great significance for the diagnosis of circulatory system infections such as bacteremia and sepsis.

[0003] However, existing fully automated blood culture systems have some problems. Among the existing domestic brands, some products only automate the incubation and detection parts, while automated products from brands such as bioMérieux (France), Brady (USA), and Deere (Zhuhai) achieve full-process automation, but they all use a single-sided culture bottle incubation array layout. The culture bottles are prone to tipping over during upright transport, requiring complex structural design to achieve stable transport, resulting in complex structure, high cost, and poor stability.

[0009] Furthermore, the swing oscillation mechanism includes a rotating motor, an eccentric wheel, and a swing arm. The rotating motor is installed on the outside of the culture bottle incubation array. An eccentric wheel is fixedly fitted at the output end of the rotating motor. The upper end of the swing arm is connected to the eccentric wheel, and the lower end is connected to a swing side plate via a pin.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] Please see Figure 1-10 This utility model provides a technical solution for a fully automated blood culture instrument: Example

[0030] according to Figure 1 , Figure 2 and Figure 3As shown, the fully automated blood culture instrument includes an insulated chamber 1 and a multi-dimensional automatic mechanical gripper mechanism 4. A double-sided culture flask incubation array 2 is arranged symmetrically within the insulated chamber 1, located on the front and rear walls or left and right walls inside the chamber. Each side of the culture flask incubation array 2 consists of multiple sets of honeycomb-shaped modules 21 arranged vertically, each with incubation, detection, and oscillation functions, used for blood culture within the culture flasks. By symmetrically arranging the culture flask incubation array 2 on both sides within the insulated chamber 1, the utilization rate of the internal space of the blood culture instrument can be increased compared to a single-sided arrangement. A horizontal culture flask transport device 5 is installed on the fully automated blood culture instrument, embedded on one side of the insulated chamber 1. The culture flasks to be cultured are transported via an automatic conveyor belt 52 at the bottom of the horizontal culture flask transport device 5. The bottles are conveyed to the bottle retrieval window, scanned, and the liquid level is detected before being grasped by the multi-dimensional automatic mechanical gripper 4 and placed into an empty culture bottle incubator 213 for incubation. An XY linear motion module 3 is set between the two-sided culture bottle incubation array 2, and a multi-dimensional automatic mechanical gripper 4 is set on the XY linear motion module 3. The multi-dimensional automatic mechanical gripper 4 consists of a 360-degree turntable 42, a linear guide rail 43, and an electric gripper 44. The multi-dimensional automatic mechanical gripper 4 is placed in the middle of the two-sided culture bottle incubation array 2. Through the cooperation of the 360-degree turntable 42, the linear guide rail 43, and the electric gripper 44, it can grasp and place culture bottles on both sides, realizing multi-dimensional grasping of objects in space. This allows the multi-dimensional automatic mechanical gripper 4 to move in multiple dimensions and accurately grasp culture bottles between the two-sided culture bottle incubation array 2.

[0031] like Figure 4 and Figure 5 As shown, the culture flask incubation array 2 mainly includes a honeycomb module 21 and a swinging oscillation mechanism 22 that controls the swinging of the honeycomb module 21. The honeycomb module 21 in the fully automated blood culture instrument is existing technology and is only briefly described here. Multiple honeycomb modules 21 can be arranged vertically in each culture flask incubation array and are limited by the outer shell of the culture flask incubation array. A single honeycomb module 21 consists of a culture rack 216 and a culture flask warming bath 213. Multiple culture flask warming baths 213 are arranged in layers in the culture rack 216. The culture flask warm bath 213 is provided with a perforated spring piece 215 for placing and clamping the culture flask. A heating module 212 is installed in the honeycomb module 21. The heating module 212 is composed of a heating plate inserted between the double-layer culture flask warm bath 213 to generate heat and provide a suitable culture environment for blood culture. A detection module 211 is installed at the tail of the culture rack 216 to detect the microbial culture results in the culture flask (detecting the presence or absence of microorganisms), and to control the temperature and system operation. A cover plate 214 is fixed at the front of the culture rack 216.

[0032] The XY linear motion module 3 can employ various mechanical structures to achieve linear movement, such as gear and rack transmission, ball screw transmission, linear slider guide, belt or chain transmission, etc., which will not be listed here. This embodiment takes a linear guide module as an example: Figure 7 As shown, the XY linear motion module 3 includes an X-axis motion module 31 and a Y-axis motion module 32. Two X-axis motion modules 31, consisting of guide rails and sliders, are symmetrically arranged parallel to each other at the top and bottom of the insulation box 1. The Y-axis motion module 32 is slidably mounted on the slider of the X-axis motion module 31. The Y-axis motion module 32 moves left and right on the X-axis motion module 31 and is positioned between the culture bottle incubation array 2 with a double-sided layout. It consists of guide rails and sliders. A multi-dimensional automatic mechanical gripper mechanism 4 is mounted on the slider of the Y-axis motion module 32 and moves up and down on the Y-axis motion module 32. Thus, the XY linear motion module 3 enables the multi-dimensional automatic mechanical gripper mechanism 4 to move planar between the culture bottle incubation array 2 with a double-sided layout, allowing the multi-dimensional automatic mechanical gripper mechanism 4 to move to any culture bottle placement position in the double-sided culture bottle incubation array 2.

[0033] A multi-dimensional automated mechanical gripper mechanism 4 is mounted on an XY linear motion module 3. Driven by the XY linear motion module 3, it moves planar between the two-sided culture flask incubation array 2. Conventional automated mechanical gripper mechanisms mainly consist of linear guides and grippers. The linear guides drive the grippers to move back and forth, thus gripping the culture flasks. This method of using linear guides in conjunction with electric grippers to grasp culture flasks is existing technology and will not be elaborated further here. This solution utilizes a two-sided culture flask incubation array 2. To accommodate this array, the specific structure of the multi-dimensional automated mechanical gripper mechanism 4 provided in this solution is as follows: Figure 8 As shown, the system includes a 360-degree turntable 42, a linear guide rail 43, and an electric gripper 44. The 360-degree turntable 42 is mounted on the XY linear motion module 3 and is driven by a drive mechanism to achieve 360° rotation. The linear guide rail 43 is horizontally mounted on the front side of the 360-degree turntable 42. The electric gripper 44 is slidably mounted inside the linear guide rail 43, and can automatically grip culture flasks by moving back and forth on the linear guide rail 43. By setting the 360-degree turntable 42 to drive the electric gripper 44 to rotate 360° in all directions, and in conjunction with the planar movement of the XY linear motion module 3, it is possible to achieve omnidirectional gripping and placement of culture flasks on both sides of the culture flask incubation array 2.

[0034] like Figure 1 and Figure 9As shown, the horizontal culture bottle transfer device 5 is installed on one side of the insulated box 1. It consists of a transfer box 51, an automatic conveyor belt 52, a liquid level detector 53, and a barcode scanner 54. The transfer box 51 is embedded in one side of the insulated box 1, and the number of culture bottle incubation arrays 2 on the same side is less than that on the other side, providing space for the horizontal culture bottle transfer device 5. The direction of the transfer box 51 facing the outside of the insulated box 1 is the culture bottle inlet. An automatic conveyor belt 52 is horizontally installed at the bottom of the transfer box 51. The culture flasks placed inside are transported forward by the automatic conveyor belt 52. A barcode scanner 54 is installed on the top of one end of the transport box 51 in the transport direction to scan and identify the corresponding culture flask information. A liquid level detector 53 is installed on the side to monitor the liquid level in the culture flask. A mechanical gripper bottle picking window 56 is set on the rear side of the transport box 51 at the end of the automatic conveyor belt 52. After scanning and detection, the culture flasks are picked up by the multi-dimensional automatic mechanical gripper mechanism 4 at the bottle picking window 56 and placed into the empty culture flask incubator 213 for culture.

[0035] The number of culture bottle incubation arrays 2 and honeycomb modules 21 on both sides can be reasonably planned and set according to the internal space of the blood culture instrument. Two culture bottle recovery chambers 6 are placed inside the incubation box 1, which are divided into positive bottle chambers and negative bottle chambers. Positive bottle chambers and negative bottle chambers can be set on either side of the culture bottle incubation arrays 2 on both sides to collect positive and negative culture bottles after culture. After testing, the culture bottles are picked up by the multi-dimensional automatic mechanical gripper 4 and classified and placed into the positive or negative bottle chambers. Finally, they are manually removed for further testing or discarded.

[0036] In practical use, the fully automatic blood culture instrument of this utility model first manually places the culture bottle into the horizontal culture bottle conveyor 5, and then conveys it to the bottle picking window 56 via the automatic conveyor belt 52. When the culture bottle reaches the tail side of the conveyor box 51, the corresponding culture bottle information is scanned and identified by the barcode scanner 54, and the liquid level height in the culture bottle is detected by the liquid level detector 53. Then, the multi-dimensional automatic mechanical gripper mechanism 4 picks up the scanned culture bottles one by one from the bottle picking window 56 and puts them into each honeycomb module 21. Then, the swing oscillation mechanism 22 is activated to oscillate and shake the culture bottles inside. After the blood culture in the culture bottle is completed, the detection module 211 at the tail of the honeycomb module 21 detects the blood sample in the culture bottle. Then, the multi-dimensional automatic mechanical gripper mechanism 4 picks up the culture bottle according to the detection results and puts it into the corresponding positive or negative bottle compartment, and then the manual person performs the next step of detection or discards it. This process is dynamically cyclical.

[0037] During the process of gripping or placing culture bottles, the multi-dimensional automatic mechanical gripper mechanism 4 is driven by the X-axis motion module 31 to move left and right between the culture bottle incubation array 2 with a double-sided layout, and by the Y-axis motion module 32 to move up and down between the culture bottle incubation array 2 with a double-sided layout, thereby realizing the planar movement of the multi-dimensional automatic mechanical gripper mechanism 4 between the culture bottle incubation array 2 with a double-sided layout. The electric gripper 44 is driven by the 360-degree turntable 42 to rotate 360° in all directions, so as to realize the all-round gripping and placement of culture bottles on both sides of the double-sided layout of the culture bottle incubation array 2 and the bottle picking window 55, positive bottle compartment and negative bottle compartment of the culture bottle horizontal transmission device 5. Example

[0038] Based on Embodiment 1, the oscillating mechanism 22 is used to drive multiple honeycomb modules 21 to oscillate synchronously. Various oscillating mechanisms can be used, as long as they can achieve the oscillation and shaking of blood in the culture bottle. This embodiment takes an eccentric wheel and a swing arm as an example: A rotating motor is installed on the side of the culture bottle incubation array 2. The rotating motor is installed on the outside of the culture bottle incubation array shell through a motor frame. An eccentric wheel 221 is fixedly fitted at the output end of the rotating motor. A swing arm 222 is connected to the eccentric position of the eccentric wheel 221 through a pin. The upper end of the swing arm 222 is connected to the eccentric wheel 221, and the lower end is connected to a swing side plate 223 through a pin. The swing side plate 223 is connected to the end of the culture rack 216 of each honeycomb module 21 through a pin. When the rotating motor is running, it drives the eccentric wheel 221 to rotate. During the rotation of the eccentric wheel 221, the swing arm 222 is pulled to reciprocate. The reciprocating swing of the honeycomb module 21 can be achieved by the pull of the swing arm 222, thereby causing the culture bottle placed inside to swing and oscillate. Example

[0039] Based on Embodiment 1, the driving mechanism of this embodiment takes a rotary motor 41 as an example. The rotary motor 41 is mounted on the XY linear motion module 3 by a bracket. The 360-degree turntable 42 is fixed at the output end of the rotary motor 41. The operation of the rotary motor 41 can control the 360-degree turntable 42 to rotate in all directions.

[0040] The drive mechanism can be of various types and is not limited to the rotary motor 41 provided in this embodiment. Any mechanism that can control the 360-degree turntable 42 to rotate in all directions can be used here. Example

[0041] Based on Example 1, such as Figure 9 and Figure 10As shown, a diversion baffle 55 is fixed inside the transfer box 51. The diversion baffle 55 is used to separate the culture bottles inside the transfer box 51 to prevent the culture bottles from stacking up, so that they are conveyed forward one by one on the automatic conveyor belt 52, ensuring that the bottles do not overlap when they are conveyed to the end.

[0042] The rear of the transfer box 51 is also equipped with an error bottle return window 57. When errors such as bottle scanning failure, liquid level detection error, or bottle placement upside down occur, bottles that cannot be placed in the instrument for culture can be removed from here for manual verification.

[0043] The above description is only a preferred embodiment of the present utility model and does not limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
