The invention provides a blood placement method and a blood placement device, wherein the blood placement method comprises the following steps: obtaining the state information of a blood sample before the blood sample is detected to obtain a placement time, placing the blood sample in a placement area based on the placement time, and transferring the blood sample to leave the placement area after the placement is finished, thereby entering the subsequent detection step.
Description
Technical Field
The present invention relates to the field of blood processing, and more particularly to a blood processing method and a blood placement device.
Background
When blood is left in a human or animal body and is left alone for a certain period of time, physicochemical properties change, and therefore, when it is necessary to perform assay analysis on blood, the blood is left for a controlled period of time. Too long or too short a time may affect the final detection result. For example, the present study found that the serum dielectric concentration in blood changed with time, the study found that the measurement result increased when serum potassium was left for one hour compared with the immediately removed serum potassium, and the measurement result decreased when the serum potassium was left for five hours compared with the immediately removed serum potassium.
With the development of detection technology, the detection precision of blood samples is higher and higher, in other words, the quality requirements of blood samples are higher and higher. If the blood is not properly processed after leaving the living body, the accuracy of the subsequent detection results may be degraded.
At present, blood is detected, generally by a pipeline operation, and the pipeline can be static for a period of time, so that the blood is given a standing time. Obviously, when the detection pipeline is statically waited for a period of time, the subsequent detection steps cannot be carried out, and the operation efficiency of the pipeline is influenced in such a way. In addition, the pipeline is suitable for batch pipelining. Many blood samples are placed on the flow line waiting still, but not every sample is removed from the living subject at the same time, i.e. the way the flow line is controlled does not allow for precise control of the blood placement. When the time of residence of one blood sample is right, the time of residence of the other blood sample may have been too long, resulting in decomposition of the active components in the blood.

Detailed Description
The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The basic principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the invention.
It will be understood by those skilled in the art that in the present disclosure, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in an orientation or positional relationship indicated in the drawings for ease of description and simplicity of description, and do not indicate or imply that the referenced devices or components must be in a particular orientation, constructed and operated in a particular orientation, and thus the above terms are not to be construed as limiting the present invention.
It is understood that the terms "a" and "an" should be interpreted as meaning that a number of one element or element is one in one embodiment, while a number of other elements is one in another embodiment, and the terms "a" and "an" should not be interpreted as limiting the number.
Referring to fig. 1-5, a blood placement method and a blood placement device 1 according to a preferred embodiment of the present invention are illustrated.
By the blood placing method, at least one blood sample can be controlled in a good state so as to be beneficial to subsequent detection or analysis precision.
In detail, by the blood placement method, the blood sample can be controlled to a good state after leaving a living body, such as a human body or an animal body, and before the blood sample is formally detected, so as to ensure the accuracy of subsequent detection or analysis.
The blood placement method may include the steps of:
obtaining state information of the blood sample to obtain a placement time for which the blood sample needs to be placed;
placing the blood sample according to the placement time obtained by the analysis; and
selecting the blood sample after the placement is finished to allow the blood sample to be detected in a subsequent step.
In detail, after the operator has taken the blood sample, the blood sample may be transferred to the blood placement device 1. The blood placement device 1 is capable of obtaining the status information of the blood sample. The status information may include a collection time, a collection environment, such as a collection temperature, or other information.
Based on the status information, such as the collection time, the blood placement device 1 may analytically know how long the blood sample needs to be placed within the blood placement device 1. For example, when medical personnel take the blood to be tested from a living body, the blood to be tested can be loaded in a container for preservation, such as a test tube or a kit. During this step, either before or after this step, the collection time may be recorded on the surface of the tube or the kit. The recording mode can be manual recording mode or automatic recording mode. For example, medical personnel may print a time-stamped label attached to the surface of the test tube or the kit prior to sampling.
Since the time of collection has been recorded, the blood sample can be analyzed for the desired placement time by reading the label of the blood sample as it enters the blood placement device 1.
It will be appreciated that the blood sample may be sorted to a certain degree before testing, so that the same type of blood sample can enter the blood placement device 1. That is, for such blood samples, the time required to elapse after collection until detection is determined, and therefore, the time required for placement can be determined after the collection time is determined. It is of course to be understood that the blood sample may also be transferred directly to the blood device 1 without sorting.
Further, the status information may include the characteristic information of the blood sample. The characteristic information may be information of a type of the blood sample, a type of the detection, and the like. Similarly, the characteristic information of the blood sample may be printed in the test tube used to load the blood before, during or after collection. It will be appreciated that the characteristic information need not be provided in the cartridge in a directly accessible manner for privacy and the like. For example, the test tube surface may be a bar code or a two-dimensional code, and the characteristic information of the blood can be obtained by identifying the bar code or the two-dimensional code through an identification device.
The time required from when the blood is collected to when the test is performed is referred to as a waiting time, which may be different for the blood samples requiring different test items.
The characteristic information may correspond to one of the waiting times of the blood sample. That is, by acquiring the characteristic information of the blood sample, the waiting time can be obtained. The waiting time for which the blood sample has been consumed can be obtained by subtracting the collection time from the current time, the remaining waiting time being the required resting time.
Furthermore, the blood sample may not only need to be placed for a certain period of time to reach a suitable state, but also may need to be placed for a certain period of time under certain environmental conditions to reach a certain state.
The blood placement method further comprises the steps of:
obtaining the state information of the blood sample to judge whether the blood sample is in the expected environmental condition, if so, continuing to place the blood sample under the condition, and if not, adjusting the environmental condition to the expected condition.
In detail, the environmental conditions may include temperature conditions, humidity conditions, light conditions, and the like. Taking the temperature condition as an example, the blood sample may need to be placed at room temperature, if the temperature is too low, the time for placing the blood sample may need to be delayed, and if the temperature is too high, the time for placing the blood sample may need to be advanced. Similar to hen eggs, the eggs need to be incubated under appropriate conditions to allow the chicks to break, and the blood samples need to be incubated under appropriate conditions.
When a temperature detector detects that the temperature of the placement area where the blood sample is placed is lower, the temperature of the placement area can be increased through a heating device, so that the blood sample can be incubated at a desired temperature.
It will be appreciated that the placement region may be divided into separate regions for placing the blood sample separately, while the heating means may also be arranged separately so that each separate region may be temperature controlled separately. It will be appreciated that the blood sample may be heated by a heating region that is independent of the placement region. When one blood sample needs to be heated, the blood sample can be transferred to the heating area for heating, and after the heating is finished, the blood sample can be directly sent for detection or transferred to the placing area for placing.
Further, with the blood placement method, the placement time can be formed based on the state information of the blood sample and the environmental condition of the blood sample.
In detail, based on the state information of the blood sample, the standing time of the blood sample under preset environmental conditions can be determined. Further, under the actual environmental conditions of the blood sample, the resting time can be corrected to obtain a more accurate resting time, as shown with reference to fig. 5.
For example, the waiting time of the blood sample is 1 hour at room temperature, that is, the blood sample needs to be tested within 1 hour. Since 20 minutes have elapsed since the blood sample was collected to the device placed for placement, then the theoretical placement time should be 40 minutes. Whereas the temperature condition among the environmental conditions of the blood sample obtained in real time at present is 15 ℃, the standing time can be corrected to 50 minutes by the correlation between the state of the blood sample and the environmental conditions established in advance.
In this way, the placing time can be automatically changed without changing the environmental conditions, which is very convenient. This approach is particularly useful in one type of scenario, where, for example, one type of the blood sample is intended to be placed at room temperature and another type of the blood sample is intended to be placed at 15 ℃. In the present embodiment, the blood samples of the two types need to be placed in two different devices respectively, and the blood samples can be adapted to the environmental conditions by changing the placing time, so that the two types of blood samples can be incubated simultaneously in the same device.
According to another aspect of the present invention, there is provided a blood placement device 1, as shown in fig. 3, wherein the blood placement device 1 comprises a placement portion 10, a transfer unit 20, a processing unit 30, and a blood sample identification unit 40, wherein the blood sample identification unit 40 and the processing unit 30 are communicably connected, and the processing unit 30 and the transfer unit 20 are communicably connected.
The blood sample recognition unit 40 is configured to obtain the status information of the blood sample, and the processing unit 30 analyzes and obtains the placement time corresponding to the blood sample based on the status information obtained by the blood sample recognition unit 40. The transfer unit 20 is communicably connected to the processing unit 30 to operate on the blood sample based on the placement time so that the blood sample stays on the placement section 10, and after the placement time elapses, transfers the blood sample again to perform the next detection step.
The placing section 10 is used for placing the blood sample. It is to be understood that the placement section 10 may be independent of the line for testing the blood sample. That is, whether the pipeline is operated or not does not affect the placing section 10.
The transfer unit 20 is used for controlling the blood sample to change the position of the blood sample, for example, the transfer unit 20 may transfer the blood sample from a previous device to the placing portion 10, or may transfer the placed blood sample away from the placing portion 10.
The placement portion 10 has a placement area 100. it is understood that the placement portion 10 may be an open configuration or a relatively closed configuration, adjusted based on the degree of control over the environmental conditions. It is understood that the placement section 10 may be, but is not limited to, a platform or a placement cabin.
The blood samples outside the placement unit 10 may be placed on the placement unit 10 in a batch by the transfer unit 20, or may be placed one by one in the placement area 100 of the placement unit 10 by the transfer unit 20. The transfer unit 20 may be, but is not limited to, a conveyor track or a robotic arm. By means of the transfer unit 20, the blood sample can automatically enter the placement section 10 or automatically leave the placement section 10. The transfer unit 20 is implemented as a robot arm and the number of the robot arms may be one or more. It will be appreciated that the transfer unit 20 is not essential and that the blood sample may be manually accessed. According to another embodiment of the present invention, as shown in fig. 6, the transfer unit 20 may be independently provided to the placing section 10.
The blood sample identification unit 40 can identify the blood sample, for example, identify the collection time, so that the processing unit 30 can analyze the placement time. The blood sample identification unit 40 may comprise a plurality of detectors, and the type of detector may be different, for example the detector may be a camera, an infrared detector, an RF detector, etc.
The blood sample discrimination unit 40 may perform the detection before the blood sample is placed in the placement unit 10, and if the waiting time of the blood sample at this time is sufficient, the blood sample may be directly subjected to the detection step without being placed in the placement unit 10.
If the processing unit 30 analyzes and judges that the waiting time for the blood sample is not yet sufficient based on the data detected by the blood sample recognition unit 40, the processing unit 30 sends a signal to the transfer unit 20, and the transfer unit 20 transfers the blood sample to the placement area 100 of the placement portion 10 for a sufficient waiting time. That is, after the standing time, the transferring unit 20 transfers the blood sample again to transfer the blood sample to a subsequent testing step.
If the processing unit 30 analyzes and judges that the waiting time of the blood sample exceeds a predetermined range based on the data detected by the blood sample recognition unit 40, which may have an adverse effect on the detection result, the transfer unit 20 transfers the blood sample to a recovery area of a recovery unit 50, so that the blood sample cannot directly enter the subsequent detection step. The blood may be re-sampled by the medical personnel concerned, in such a way that the accuracy of the subsequent test results can be guaranteed to avoid the blood being lost to the testing step.
It will be appreciated that if the processing unit 30 determines that the waiting time of the blood sample has exceeded a predetermined range based on the detection of data by the blood sample recognition unit 40, which may have an adverse effect on the detection result, the processing unit 30 can issue an alarm signal, which is sent to the relevant medical staff for timely re-collection of the blood sample by the medical staff.
Further, the blood placement device 1 may further comprise an identification unit 60, wherein the identification unit 60 is communicatively connected to the transfer unit 20, and the identification unit 60 is used for identifying the blood sample so that the transfer unit 20 can accurately transfer the blood sample. It is understood that the blood sample identification unit 40 and the identification unit 60 may be the same device, or may be two separate devices, which may be the same or different.
It is understood that the blood sample recognition unit 40 may perform detection after the blood sample is placed in the placement region 100 of the placement portion 10, so that the processing unit 30 can process the time period required for obtaining the blood sample.
Further, the placing section 10 may further include an environment detecting unit 70 and an environment adjusting unit 80, wherein the environment detecting unit 70 is communicably connected to the processing unit 30, and the environment adjusting unit 80 is communicably connected to the processing unit 30.
The environment detection unit 70 is provided in the placement section 10 to detect an environmental condition of the placement area 100, such as a temperature condition, a humidity condition, or a light condition. The environment detecting unit 70 may include a temperature detector, a humidity detector, or an illumination detector. After the environment detecting unit 70 detects the placement area 100 of the placement unit 10, the processing unit 30 determines whether the current environment condition needs to be adjusted based on the data detected by the environment detecting unit 70, if so, the processing unit 30 sends a signal to the environment adjusting unit 80, and the environment adjusting unit 80 is adapted to adjust the environment condition of the placement area 100 of the placement unit 10.
The environment adjusting unit 80 may be an air conditioner to adjust the temperature or humidity, and the environment adjusting unit 80 may include a lighting device to adjust the intensity and position of the illumination.
By the environment detecting unit 70 and the environment adjusting unit 80 of the placing section 10, the environmental condition of the placing area 100 of the placing section 10 can be adjusted.
It is understood that the placement area 100 of the placement section 10 may be divided into independent small areas, and the number of the environment adjustment units 80 may be plural and may be respectively disposed in the independent small areas. The environment adjusting unit 80 may include a plurality of the heating devices. The heating means is used to independently control the temperature of a plurality of independent small areas of the placement area 100. It is understood that the heating means may be provided separately from the placement region 100 of the placement section 10, and may be placed in a heating region provided by the heating means when the blood sample needs to be maintained under a certain temperature condition. That is, when the blood sample has a heating requirement or a cooling placement requirement, it can be transferred to a separate heating region without changing the environmental conditions of the placement region 100. The heating device is detachably mounted to the placing section 10 so that the heating device can be used as a separate accessory.
It is worth mentioning that the environmental condition of the placement area 100 of the placement unit 10 may be adjusted based on the current environmental condition detected by the environment detection unit 70, or may be adjusted based on the type of the blood sample.
In detail, the blood sample identification unit 40 may obtain the state information of the blood sample, which includes the characteristic information, so that the environmental condition expected for the blood sample may be obtained. The processing unit 30 may send a signal to the environment adjusting unit 80 to adjust the placing area 100 of the placing part 10 when the current environmental condition and the expected environmental condition differ by more than a certain limit by comparing them.
Further, according to an embodiment of the present invention, referring to fig. 4, when the current environmental condition does not satisfy the environmental condition expected by the blood sample, the processing unit 30 performs analysis based on the data obtained by the blood sample recognition unit 40 and the environmental detection unit 70, and if the difference between the two is within a certain range, the processing unit 30 directly corrects the placement time so that the incubation of the blood sample is completed under the current environmental condition. If the difference exceeds a certain range, the processing unit 30 sends a signal to cause the environmental adjustment unit 80 to adjust the environmental conditions to meet the blood sample placement requirements.
For example, the temperature of the current environment is 0 ℃, the environment detection unit 70 detects this data and sends the data to the processing unit 30, the processing unit 30 knows that the temperature condition of the current expected environment condition of the blood sample is 18 to 25 ℃ based on the information detected by the blood sample identification unit 40, and the processing unit 30, after analyzing, finds that the current temperature is greater than the expected temperature by a preset range, and thus the processing unit 30 sends a signal, so that the environment adjustment unit 80 adjusts the environment condition, and the environment temperature returns to 18 to 25 ℃, so as to meet the condition of incubating the blood sample.
Further, the blood placement device 1 can be operated in batches on the blood samples, while also being able to be operated specifically on a single blood sample.
When a plurality of blood samples are placed on the placement area 100 of the placement section 10, a single blood sample can be identified by the data obtained by the blood sample identification means 40, so that the placement time required for the blood sample can be known specifically based on the blood sample. It will be understood that a batch of the blood samples may be placed on the placement section 10 at the same point in time, but the waiting times that elapse may be different. For example, the blood sample a may be collected at 10 o ' clock, and the blood sample b may be collected at 10 o ' clock and 10 o ' clock, and then collectively fed to the placing section 10. After the blood sample identification means 40 and the processing means 30 are analyzed, the blood sample a needs to be incubated in the placement portion 10 for 1 hour, and the blood sample b needs to be incubated in the placement portion 10 for 1 hour and 10 minutes.
After 50 minutes, the transfer unit 20 may pick the blood sample b to carry the blood sample b away from the placement portion 10. After 1 hour and 10 minutes, the transfer unit 20 may pick up the blood specimen a to carry the blood specimen a away from the placement section 10.
It will be appreciated that the transfer unit 20 may be provided with identification means to accurately identify the blood sample. Alternatively, the transfer unit 20 may acquire the position coordinates of the blood sample of the target based on the information of the blood sample obtained by the blood sample recognition unit 40, thereby completing the accurate transfer of the blood sample.
It will be appreciated by persons skilled in the art that the embodiments of the invention described above and shown in the drawings are given by way of example only and are not limiting of the invention. The objects of the invention have been fully and effectively accomplished. The functional and structural principles of the present invention have been shown and described in the examples, and any variations or modifications of the embodiments of the present invention may be made without departing from the principles.
