Description

Technical Field

[0001] The present invention relates to the field of culture instruments, in particular to a blood culture instrument. Background Art

[0002] A blood culture instrument is a microbiological analysis device used to test blood samples for the presence of bacteria. It plays a crucial role in the diagnosis and treatment of patients with sepsis and bacteremia. To ensure optimal bacterial growth and improve the accuracy of test results, the blood sample must be maintained at a relatively stable temperature, typically 35±1.5°C, which is higher than room temperature.

[0003] Blood culture apparatuses usually use air circulation heating inside the box to create a relatively stable temperature environment for culture bottles. However, since blood culture apparatuses usually need to place a large number of culture bottles, the box of the blood culture apparatus needs to be opened and closed frequently to store and access the culture bottles, resulting in the entry of cold air from the outside that is lower than the constant temperature environment inside the box, affecting the incubation process of other blood culture bottles in the box. In addition, culture bottles that have just been placed and are still at room temperature will also have an impact on the surrounding temperature, resulting in large temperature fluctuations in the box and an inability to maintain a stable constant temperature environment.

[0004] Therefore, it is necessary to propose a blood culture instrument to solve the above technical problems existing in the prior art. Summary of the Invention

[0023] The two ball pins are both provided with connecting grooves, and the two connecting grooves are respectively matched with the two push-pull rods.

[0024] The present invention has the following beneficial effects:

[0025] 1. This blood culture instrument uses chains to form a fully automated shelf for mobile storage and retrieval of blood culture bottles. Several mounting mechanisms are installed on the shelf to support the blood culture bottles, and the blood culture bottles can rotate and shake horizontally and move radially relative to the chains. When storing and retrieval blood culture bottles, several access ports are provided with insulation chambers. The mounting seat first enters a closed first insulation chamber, isolating it from the temperature inside the constant temperature chamber. The blood culture bottles are then placed or removed. The temperature control mechanism installed on the insulation chamber allows the environment inside the first insulation chamber to return to equilibrium with the temperature inside the constant temperature chamber. Only then is the first insulation chamber opened and the mounting seat returned to the constant temperature chamber. This minimizes the disruption to the constant temperature environment of the constant temperature chamber caused by cold air entering when the door is opened and closed, as well as by the lower temperature of newly placed blood culture bottles, effectively ensuring that the culture environment of the blood culture bottles remains at a constant temperature.

[0026] 2. In this blood culture instrument, when the temperature of the first insulation chamber drops due to contact with the outside environment due to accessing blood culture bottles, the temperature control mechanism supplies heat to the first insulation chamber until the temperature inside the first insulation chamber converges with that inside the incubator. During this time, the first insulation chamber is not heated by directly supplying hot air from the incubator. Instead, a second insulation chamber is provided within the insulation chamber, which is indirectly connected to the first insulation chamber via the second insulation chamber. Under normal conditions, the three chambers maintain one-way communication and can be considered a single entity. Heat is continuously supplied to the second and first insulation chambers without affecting the constant temperature environment within the incubator. When the temperature of the first insulation chamber drops and heat is supplied again, the direct connection between the second insulation chamber and the incubator is severed, and the heat stored in the second insulation chamber is used to heat the first insulation chamber. The heat in the second insulation chamber is then slowly replenished. This avoids the slight impact on the constant temperature environment within the incubator caused by the instantaneous supply of hot air, further enhancing the maintenance of the constant temperature environment within the incubator.

[0027] 3. In this blood culture instrument, as the mounting mechanism and the blood culture bottles it carries continuously operate along the chain, the blood culture bottles' continuous movement within the incubator along the chain's trajectory increases their contact with the hot airflow generated by the incubator's heating device, resulting in more even heating compared to traditional fixed placement. Furthermore, the design of the first smooth section and the wavy section in the guide groove ensures that the mounting base supporting the blood culture bottles alternates between oscillation and balance as the chain operates, significantly improving incubation efficiency compared to traditional incubation methods that rely on continuous oscillation.

DETAILED DESCRIPTION

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] Example 1

[0042] Typically, blood culture bottles 500 are placed in an incubator 100 under constant temperature conditions for blood culture. However, since a large number of blood culture bottles 500 need to be cultured within a single incubator 100, opening and closing the door when inserting new blood culture bottles 500 and removing old ones can cause cold air, which is below the 35°C ± 1°C internal temperature, to enter the incubator 100. Furthermore, the newly inserted blood culture bottles 500 are also at a lower temperature. Both of these factors can cause some degree of damage to the constant temperature culture environment within the incubator 100. Therefore, to address the aforementioned issues, Example 1 is proposed.

[0043] See also Figures 1-10 A blood culture instrument includes a constant temperature box 100, wherein a plurality of support frames 110 are provided in the constant temperature box 100, a conveying mechanism 200 is provided on the support frames 110, and the conveying mechanism 200 includes a chain 210 provided on the support frames 110;

[0044] Several mounting mechanisms 300 are provided on the chain 210 . The mounting mechanisms 300 include mounting seats 310 connected to the chain 210 . The mounting seats 310 are used to carry blood culture bottles 500 .

[0045] The constant temperature box 100 is further provided with a plurality of insulating chambers 120 corresponding to the plurality of support frames 110. A first insulating cavity 130 is provided in the insulating chamber 120. The insulating chamber 120 is provided with a first opening and closing door 140, a second opening and closing door 150 and a temperature control mechanism 400.

[0046] When storing or accessing a blood culture bottle 500, the mounting seat 310 is moved into the first temperature-isolating chamber 130, and the first and second doors 140, 150 are used to seal and insulate the first temperature-isolating chamber 130. The temperature control mechanism 400 is then used to bring the first temperature-isolating chamber 130 and the interior of the thermostat 100 to the same temperature, and the mounting seat 310 is then returned to the thermostat 100.

[0047] The conveying mechanism 200 further includes a plurality of rotating shafts 220 rotatably mounted on the support frame 110 , each of the rotating shafts 220 being provided with a sprocket 230 , the chain 210 being meshed with the plurality of sprockets 230 , and a servo motor 240 being provided on the support frame 110 , the output shaft of the servo motor 240 being coaxially connected to one of the rotating shafts 220 ;

[0048] A fixed seat 320 is provided on the chain 210 , a sliding seat 330 is slidably provided on the fixed seat 320 , a mounting seat 310 is provided on the sliding seat 330 , and two elastic clips 340 are symmetrically provided on the mounting seat 310 for mounting a blood culture bottle 500 ;

[0049] The mounting mechanism 300 further includes a displacement assembly 350 , which is used to drive the mounting seat 310 to move between the constant temperature box 100 and the first temperature isolation chamber 130 .

[0050] In this embodiment, a temperature control system is installed within the incubator 100, comprising a cooling system, a heating system, a control system, an air circulation system, and a sensor system. These components, as conventional technology, are not shown in the illustrations. During blood culture, the heating device within the incubator 100 maintains a constant temperature above room temperature for the blood culture bottles 500 within the incubator 100.

[0051] The support frame 110 is composed of two symmetrical plates. The conveying mechanism 200 is installed between the two plates. The servo motor 240 drives one of the rotating shafts 220 and sprockets 230 to rotate, which can drive the remaining rotating shafts 220 and sprockets 230 to rotate and the chain 210 to run.

[0052] The mounting mechanisms 300 mounted on the chain 210 are used to secure the blood culture bottles 500. Specifically, a fixing seat 320 is mounted on a link of the chain 210, and a sliding seat 330 is slidably mounted within the fixing seat 320. Both are U-shaped, and the mounting seat 310 is mounted on the sliding seat 330. Two elastic clips 340 symmetrically mounted on the mounting seat 310 are used to clamp and secure the blood culture bottles 500.

[0053] The insulation chamber 120, mounted in the middle of the front end of the support frame 110, is made of an insulating material. A first insulation chamber 130 defined therein is used for temporary storage of blood culture bottles 500 during access. The rear opening of the first insulation chamber 130 is controlled by a first opening / closing door 140. The notch in the first opening / closing door 140 mates with the portion of the mounting base 310 extending into the first insulation chamber 130. The front opening of the first insulation chamber 130 is controlled by a second opening / closing door 150. Both the first opening / closing door 140 and the second opening / closing door 150 are made of insulating material and can be opened and closed by a motor-driven rack mounted on the door body. As is conventional in the art, the specific structure and operating principle of the first opening / closing door 140 and the second opening / closing door 150 are not described in detail herein.

[0054] First, under normal conditions, the temperature in the first insulation chamber 130 tends to be the same as the constant temperature environment in the constant temperature box 100 through the action of the temperature control mechanism 400. When taking out a blood culture bottle 500 from the constant temperature box 100, the first switch door 140 is first opened, and then the servo motor 240 drives the chain 210 to rotate and move the mounting mechanism 300 carrying the blood culture bottle 500 to a horizontal forward position. At this time, the sliding seat 330 can be driven to move forward as a whole through the displacement assembly 350.

[0055] Once the mounting seat 310 has moved into the first temperature-isolating chamber 130, the first door 140 is closed to seal the first temperature-isolating chamber 130 again. The second door 150 is then opened, and the worker can remove the blood culture bottle 500 from the front opening of the first temperature-isolating chamber 130. At this point, the temperature within the first temperature-isolating chamber 130 is affected by the room temperature and lowered. The second door 150 is then closed, and after a period of time, the temperature within the first temperature-isolating chamber 130, controlled by the temperature control mechanism 400, returns to the constant temperature of the incubator 100. The first door 140 is then opened, and the displacement assembly 350 drives the slide 330 to move backwards as a whole, returning it to the incubator 100.

[0056] The same applies when storing a new blood culture bottle 500. First, open the second door 150 to place the blood culture bottle 500. Wait until the temperature of the new blood culture bottle 500 and the mounting base 310 in the first insulation chamber 130 reaches the same temperature as that in the constant temperature box 100. Then, open the first door 140 to place the new blood culture bottle 500 in the constant temperature box 100.

[0057] In addition, the specific opening of a second opening and closing door 150 to store and retrieve a blood culture bottle 500, the operation of a chain 210, the control of the internal environmental temperature, etc. are all fully automated based on this.

[0058] Example 2

[0059] If the constant temperature is maintained by continuously heating the constant temperature box 100 by only delivering the hot air flow in the constant temperature box 100 into the first insulation chamber 130, the process of delivering the hot air flow into the constant temperature box 100 itself will have a slight impact on the constant temperature environment in the constant temperature box 100. In order to further solve this problem, Example 2 is proposed.

[0060] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 7 The temperature control mechanism 400 includes a second insulation chamber 410 opened in the insulation chamber 120. The insulation chamber 120 is provided with two connecting pipes 420. The first insulation chamber 130 and the second insulation chamber 410 are connected through one of the connecting pipes 420. The inner cavity of the constant temperature box 100 and the second insulation chamber 410 are connected through the other connecting pipe 420.

[0061] A solenoid valve 430 and a one-way valve 440 are provided in each of the two connecting pipes 420 . The two one-way valves 440 are used to limit the one-way flow of air from the inner cavity of the constant temperature box 100 to the first temperature insulation cavity 130 .

[0062] In this embodiment, a second insulation chamber 410 is additionally provided in the insulation chamber 120. The thermostat 100 is not directly connected to the first insulation chamber 130, but is indirectly connected via the second insulation chamber 410. When the thermostat 100 is in a constant temperature and continuous heating process, the hot air in the thermostat 100 first passes through the first insulation chamber 410. Figure 7 The two connecting pipes 420 and the one-way valve 440 in the second temperature insulation chamber 410 and the first temperature insulation chamber 130 are heated and maintained at a constant temperature.

[0063] After the temperature in the first insulation chamber 130 drops due to the opening of the second door 150, the upper solenoid valve 430 is closed, leaving only the lower solenoid valve 430 open. This allows the heat stored in the second insulation chamber 410 to flow into the first insulation chamber 130 due to the temperature difference between the two sides, thereby heating the first insulation chamber 130 without directly consuming the heat in the constant temperature box 100. After the first door 140 is opened to return the mounting base 310 to the constant temperature box 100, the upper solenoid valve 430 is opened again to replenish the heat in the second insulation chamber 410.

[0064] It should be noted that temperature monitoring devices such as sensors can be installed in the thermostat 100, the first insulation chamber 130, and the second insulation chamber 410 to control the opening and closing of the first door 140, the opening and closing of the two solenoid valves 430, and the operation of the heating device in the thermostat 100 through temperature monitoring. This technical means is conventional and is not shown in the legend.

[0065] Example 3

[0066] In order to make the operation more convenient when installing the blood culture bottle 500 on the mounting seat 310 or removing the blood culture bottle 500 from the mounting seat 310, embodiment 3 is proposed;

[0067] This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 3-Figure 10 The elastic clip 340 includes a middle section 341, a rear section 342 and a front section 343, wherein the middle section 341 is connected to the mounting seat 310, the rear section 342 fits with the body of the blood culture bottle 500, and the front section 343 fits with the bottleneck of the blood culture bottle 500.

[0068] In this embodiment, the elastic clip 340 is made of elastic material. The middle section 341 is connected to the mounting seat 310 as a fulcrum. The front section 343 that fits the bottleneck of the blood culture bottle 500 is closer to the middle of the mounting seat 310, while the rear section 342 is wider. When the blood culture bottle 500 is placed, the part of the body of the blood culture bottle 500 with a larger diameter will first be Figure 10 Pushing the two front sections 343 backward causes the two elastic clips 340 to rotate backward. The two rear sections 342 then open, one above the other, allowing the blood culture bottle 500 to pass smoothly. Once the body of the blood culture bottle 500 has passed and the neck of the bottle reaches the front sections 343, the front sections 343 have room to rebound and rotate back, allowing the two rear sections 342 to grip the blood culture bottle 500 and secure it in place. To remove the blood culture bottle 500, pinch the two middle sections 341 inward to lift the rear sections 342, allowing the bottle 500 to be easily removed.

[0069] Example 4

[0070] In addition to the constant temperature environment, the culture process of the blood culture bottle 500 also requires a certain degree of shaking to assist blood culture. For this purpose, Example 4 is proposed.

[0071] This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 2-Figure 11 The mounting base 310 is rotatably connected to the slide 330 , and the mounting mechanism 300 further includes a shaking assembly 360 for driving the mounting base 310 to rotate back and forth on the slide 330 to shake the blood culture bottle 500 ;

[0072] The shaking assembly 360 includes two connecting rods 361 symmetrically arranged on the sliding seat 330. The fixed seat 320 has two first sliding grooves 362 symmetrically formed thereon. The two connecting rods 361 are slidably connected to the two first sliding grooves 362 respectively.

[0073] The two connecting rods 361 are each provided with a sliding rod 363. The mounting base 310 is symmetrically provided with two second sliding grooves 364. The two sliding rods 363 are respectively slidably connected in the two second sliding grooves 364.

[0074] The two connecting rods 361 are each provided with a ball pin 365. The support frame 110 is symmetrically provided with two guide grooves 366. The two ball pins 365 are respectively slidably connected in the two guide grooves 366.

[0075] The guide groove 366 includes a plurality of first smooth sections 3661 and a plurality of wave sections 3662 , wherein the crests of the wave sections 3662 on one side correspond to the troughs of the wave sections 3662 on the other side.

[0076] The guide groove 366 further includes a second smooth section 3663 and a horizontal section 3664 . A port on one side of the horizontal section 3664 is connected to the second smooth section 3663 , and a port on the other side of the horizontal section 3664 is aligned with the insulation chamber 120 .

[0077] In this embodiment, the mounting base 310 is rotatably mounted on the slide 330 via two upper and lower shafts. Two connecting rods 361 are movable through the slide 330 from the left and right ends and can slide back and forth along the first sliding groove 362.

[0078] When the chain 210 is running, when the fixed seat 320 slides and drives the two ball pins 365 to be in the two first smooth sections 3661, the two connecting rods 361 are at the same distance from the middle of the slide seat 330. At this time, the mounting seat 310 remains horizontal, and the two slide rods 363 are respectively located in the middle of the two second slide grooves 364.

[0079] When the chain 210 continues to run, driving the two ball pins 365 to slide to two of the wave segments 3662, the trough of the left wave segment 3662 facing the middle slide 330 is aligned with the crest of the right wave segment 3662 facing the middle slide 330, that is, the two guide grooves 366 are not mirror-symmetrical based on the center line of the slide 330, but are a left-right movement and replication relationship.

[0080] During the sliding process within the two wave segments 3662, the distance between the two connecting rods 361 and their ends remains constant, but the two connecting rods 361 as a whole undergo a left-right reciprocating motion. When the two connecting rods 361 as a whole deflect to the left, the mounting base 310 is driven to rotate leftward. When the two connecting rods 361 as a whole deflect to the right, the mounting base 310 is driven to rotate rightward. During this process, the two sliding rods 363 slide along the two second sliding grooves 364 respectively.

[0081] As a result, the mounting base 310 will continue to shake as the chain 210 runs through several wavy sections 3662, while the first smooth section 3661 remains balanced, alternating between shaking and balance to improve the auxiliary incubation effect on the blood culture bottle 500.

[0082] Example 5

[0083] In order to achieve the goal of driving the entire sliding seat 330 forward when it is displaced to the horizontal forward position so that the mounting seat 310 enters the first temperature insulation chamber 130, embodiment 5 is proposed;

[0084] This embodiment is an improvement made on the basis of embodiment 4. For details, please refer to Figure 3-Figure 11The displacement assembly 350 includes two electric push rods 351 symmetrically arranged on the support frame 110. The output ends of the two electric push rods 351 are both provided with a push-pull rod 353. Two third sliding grooves 352 are symmetrically opened on the support frame 110, and the two third sliding grooves 352 are respectively connected to the two horizontal sections 3664;

[0085] The two ball pins 365 are each provided with a connecting groove 354 , and the two connecting grooves 354 are respectively engaged with the two push-pull rods 353 .

[0086] In this embodiment: Figure 11 As shown, the guide groove 366 in the figure represents the movement trajectory of the ball pin 365. When the two ball pins 365 are displaced to the middle section of the front side, the ball pins 365 enter the second smooth section 3663. At this time, the mounting base 310 remains horizontal and forward. By allowing the two electric push rods 351 to drive the two push-pull rods 353 to reach a position that fits with the two connecting grooves 354 in advance. After the two ball pins 365 are displaced to the middle, the two push-pull rods 353 are inserted into the two connecting grooves 354. At this time, the two electric push rods 351 operate synchronously to drive the two push-pull rods 353 to move back and forth, which will drive the two ball pins 365 to slide back and forth along the two horizontal sections 3664.

[0087] Furthermore, the connecting slot 354 is penetrated vertically by a ball pin 365, allowing the push-pull rod 353 to enter the connecting slot 354 from both the top and bottom sides. The ball pin 365 can reach the center position from either the top or bottom. This allows the mounting seat 310 to be moved to the front side. When a blood culture bottle 500 is to be placed or removed, the shortest distance can be intelligently calculated, thereby controlling the chain 210 to rotate forward or reverse to ensure that the mounting seat 310 reaches the front side as quickly as possible.

[0088] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0089] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
