Description

Technical Field

[0002] Fully automatic biochemical analyzers, such as Roche's Cedex biochemical analyzer, are small in size, easy to operate, highly robust and highly sensitive, making them widely used in hospitals at all levels. Doctors use fully automatic biochemical analyzers to measure various biochemical indicators of blood or other body fluids, and use these indicators as the data basis to make scientific medical diagnoses.

[0003] The stirring device is one of the important components of the fully automatic biochemical analyzer. Its main function is to evenly mix the reagents and samples in the colorimetric cup. When the blood or other body fluids in the colorimetric cup are stirred and mixed, it is necessary to monitor in real time whether the blood or other body fluids produce excessive bubbles, so as to deal with the problems that occur during the stirring process of the body fluids. The current fully automatic biochemical analyzer mainly detects whether there are bubbles in the sample and reagent source, and does not detect whether bubbles are generated during the stirring process of the sample and reagent. Because the absorbance of blood or other body fluids will be affected by bubbles, the absorbance calculated by setting the program may be inaccurate.

[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings).

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0041] See also Figure 1As shown, the present application proposes a stirring detection device 100. The stirring detection device 100 includes a mounting seat 10, a stirring rod 20, a bubble sensor 30 and an early warning member 40; the mounting seat 10 is equipped with a stirring driving member (not shown in the drawings); the stirring rod 20 is arranged below the mounting seat 10 and connected to the stirring driving member, and the stirring rod 20 is used to stir the liquid in the container below; the bubble sensor 30 is arranged below the mounting seat 10 adjacent to the stirring rod 10, and is used to detect the number of bubbles generated in the container when the stirring rod 20 stirs the liquid; the early warning member 40 is connected to the bubble sensor 30, and is used to send an early warning signal when the bubble sensor 30 detects that the number of bubbles in the container reaches a bubble number threshold.

[0042] According to the technical solution of the present application, the bubble sensor 30 and the stirring rod 20 move synchronously with the mounting base 10, and after the stirring rod 20 is inserted into the liquid in the container, the liquid can be stirred under the drive of the stirring driving member. At the same time, the bubble sensor 30 arranged adjacent to the stirring rod 20 can detect in real time the number of bubbles generated in the liquid during the stirring process, and when the number of bubbles reaches a bubble number threshold, an early warning signal is issued by the early warning member 40 connected to the bubble sensor 30.

[0043] Among them, by setting up components such as the mounting base 10, the stirring rod 20, the bubble sensor 30 and the warning element 40, the stirring and detection are automated. The operator only needs to set the stirring parameters and the bubble quantity threshold, and the device can automatically complete the stirring, and obtain the bubble quantity detection and complete the warning during the automatic stirring process. This real-time feedback mechanism helps the operator to understand the stirring effect in time and prevent the stirring from generating excessive bubbles that affect the accuracy of the absorbance data of the liquid.

[0044] Exemplarily, the container used in the technical solution of the present application is a cuvette, and the liquid to be stirred contained in the cuvette is a mixed solution of a test sample and a reagent source, and the test sample can be a blood sample or other body fluid sample.

[0045] In some embodiments, the bubble sensor 30 includes a light beam emitter (not shown in the drawings) and a light beam receiver (not shown in the drawings); the light beam emitter is used to emit a light beam to the liquid in the container; the light beam receiver is used to receive the reflected light from the bubbles generated in the container, convert the light signal generated by the reflected light into an electrical signal, and control the warning component 40 to issue a warning signal when the electrical signal reaches an electrical signal threshold; the electrical signal threshold corresponds to the bubble quantity threshold.

[0046] In this embodiment, the bubble sensor 30 emits a light beam to the liquid in the container through a light beam emitter, and the light beam receiver is responsible for receiving the reflected light from the liquid. This non-contact detection method avoids direct contact between the sensor and the liquid, thereby reducing the risk of contamination and damage.

[0047] Among them, after the light beam emitter emits the light beam, the light beam will quickly pass through the liquid to be detected in the container. When the light beam encounters bubbles, part of the light beam will be reflected, refracted or scattered. These reflected light beams, refracted light beams and scattered light beams are back-reflected light beams. The light beam receiver converts the received back-reflected light beams into electrical signals. When too many bubbles are generated during the stirring process, the electrical signals converted by the back-reflected light beams of the light beam receiver gradually increase, and when the threshold of the electrical signal is reached, the warning component 40 can be controlled to send out a warning signal. This conversion makes the detection of the number of bubbles more accurate and quantifiable.

[0048] In some embodiments, the warning component 40 is a voice broadcast module and / or a light warning module; the voice broadcast module is used to issue a warning voice, and the light warning module is used to issue a warning light.

[0049] In this embodiment, this design enriches the warning methods, improves the practicality and user experience of the stirring detection device 100, and the user can make a choice based on the specific application scenario and user preference.

[0050] The warning element 40 includes a voice broadcast module and a light warning module, so that the device can select a suitable warning method according to the actual situation and user needs. The voice broadcast module reminds the operator by issuing a warning voice, while the light warning module draws attention by issuing a warning light. This diversified warning method makes the device more flexible and convenient.

[0051] The warning light provided by the light warning module is intuitive, so that the operator can quickly notice the warning signal even in a noisy or visually restricted environment. The voice broadcast module conveys the warning information through hearing, so the operator can clearly hear the warning voice even when the vision is blocked or the ambient noise is low. This combination makes the warning signal easier to detect and understand.

[0052] For the technical solution of the present application, when the electrical signal converted by the reflected light beam receiver reaches the electrical signal threshold, the voice broadcast module can be controlled to emit a warning voice and / or the light warning module can be controlled to emit a warning light.

[0053] See also Figure 2 As shown, in some embodiments, the stirring rod 20 includes a rod body 210 and a stirring head 211; one end of the rod body 210 is connected to the stirring drive member; the stirring head 211 is connected to the other end of the rod body 210; wherein, when the stirring rod 20 stirs the liquid in the container below, the stirring head 211 is immersed below the liquid surface.

[0054] In this embodiment, the design of the stirring rod 20 includes two parts: a rod body 210 and a stirring head 211. The stirring head 211 is connected to the other end of the rod body 210 and is immersed below the liquid surface during the stirring process. This design enables the stirring head 211 to directly contact the liquid and effectively mix and stir. Further, according to the specific needs of stirring, the stirring head 211 can be designed into different shapes and sizes to adapt to the stirring characteristics and mixing requirements of different liquids.

[0055] See also Figure 3 As shown, in some embodiments, the stirring head 211 is a fan-shaped column, and the cross-sectional shape of the fan-shaped column is two mirror-symmetrical fan-shaped units 212, and the outer side of the fan-shaped column corresponds to the fan-shaped long side 2121 on the outer side of the fan-shaped unit 212, and the fan-shaped long side 2121 is an arc edge; wherein, the two fan-shaped side edges 2122 adjacent to the fan-shaped long side 2121 in each fan-shaped unit 212 are straight edges.

[0056] In this embodiment, the stirring head 211 is designed as a fan-shaped column, and the stirring head 211 includes two mirror-symmetrical fan-shaped units 212, so that the stirring head 211 can form a larger stirring area when rotating. Among them, the two fan-shaped units 212 are arranged as one body, and when the fan-shaped long side 2121 outside the fan-shaped unit 212 is an arc side, it can better contact with the liquid when the stirring rod 20 is stirring, increase the stirring efficiency, and effectively mix the various parts in the liquid.

[0057] See also Figure 4 As shown, in some embodiments, the stirring head 211 is a fan-shaped column, and the cross-sectional shape of the fan-shaped column is two mirror-symmetrical fan-shaped units 212, and the outer side of the fan-shaped column corresponds to the fan-shaped long side 2121 on the outer side of the fan-shaped unit 212, and the fan-shaped long side 2121 is an arc-shaped edge; wherein, the two fan-shaped side edges 2122 adjacent to the fan-shaped long side 2121 in each fan-shaped unit 212 are arc-shaped edges, and the two fan-shaped side edges 2122 are in a relatively concave state.

[0058] In this embodiment, the stirring head 211 is another arrangement form of a fan-shaped column. On the basis of the above-mentioned fan-shaped column, two fan-shaped side edges 2122 adjacent to the fan-shaped long side 2121 are set as arc-shaped edges, and the two fan-shaped side edges 2122 are in a relatively concave state. In this way, in the effect achieved by the above-mentioned fan-shaped column, the arc design of the fan-shaped side edges 2122 helps to smoothly push the liquid and reduce the generation of bubbles during the stirring process.

[0059] It can be understood that the above-mentioned fan-shaped column of the stirring head 211 is only one example in the present application, and the stirring head can also be set in other forms, such as a spiral column, stirring blades, etc. The specific scheme will not be repeated here.

[0060] In some embodiments, the stirring head 211 is detachably connected to the rod body 210. In this way, different stirring tasks require stirring heads 211 of different shapes, sizes or materials, or when the stirring head 211 is worn or damaged. Through the detachable connection, the operator can easily replace it with a suitable stirring head 211 to meet different stirring needs and improve adaptability. In practical applications, the detachable connection can be in various forms, such as threaded connection, snap connection, quick locking device, etc.

[0061] read Figure 1 As shown, in some embodiments, the stirring detection device 100 also includes a driving mechanism 60 and a cross arm 50; one end of the cross arm 50 is connected to the driving mechanism 60; the mounting base 10 is arranged on the cross arm 50 at the other end close to the cross arm 50; wherein the driving mechanism 60 is used to drive the cross arm 50 to rotate on the horizontal plane and to drive the cross arm 50 to move in the vertical direction.

[0062] In this embodiment, when the mounting base 10 is disposed on the cross arm 50 and the driving mechanism 60 drives the cross arm 50 to rotate in the horizontal plane and is used to drive the cross arm 50 to move in the vertical direction, the stirring rod 20 and the bubble sensor 30 on the mounting base 10 can be synchronously driven to move.

[0063] Specifically, the driving mechanism 60 drives the cross arm 50 to rotate on the horizontal plane. In this way, the stirring detection device 100 can stir and detect the liquid in the container at different positions without manually adjusting the position of the container or the device. The convenience and efficiency of operation are greatly improved, and it is particularly suitable for scenarios where multiple containers need to be continuously stirred and detected. The driving mechanism 60 can also drive the cross arm 50 to move in the vertical direction. In this way, the stirring rod 20 and the bubble sensor 30 can be accurately adjusted to the appropriate position in the container to ensure the stirring effect and the accuracy of bubble detection. No matter how the size, shape or position of the container changes, the device can adapt to and optimize the stirring and detection conditions by moving in the vertical direction.

[0064] See also Figure 1 As shown, in some embodiments, the stirring detection device 100 further includes a protective cover 70 ; the protective cover 70 is disposed on the cross arm 50 , and the range of the protective cover 70 is from one end to the other end of the cross arm 50 .

[0065] In this embodiment, the protective cover 70 is provided on the cross arm 50, covering the entire range from one end to the other end of the cross arm 50. This design effectively prevents the operator from accidentally contacting the cross arm 50 and its components (such as the mounting seat 10, the stirring drive member, etc.) during operation, thereby reducing potential safety hazards and enhancing the safety and reliability of the device. Furthermore, the protective cover 70 can be designed in coordination with the overall style of the device, so that the entire stirring detection device 100 is more beautiful and unified in appearance.

[0066] The present application also provides a fully automatic biochemical analyzer. The fully automatic biochemical analyzer includes the stirring detection device 100 as described above. The fully automatic biochemical analyzer adopts all technical solutions of all embodiments of the stirring detection device 100, and therefore has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0067] The above description is only a partial or preferred embodiment of the present application. Neither the text nor the drawings can limit the scope of protection of the present application. All equivalent structural changes made using the contents of the present application specification and drawings under the overall concept of the present application, or direct / indirect application in other related technical fields are included in the scope of protection of the present application.
