[0049] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0050] It should be noted that: similar labels and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. Meanwhile, in the description of the present application, the terms “first”, “second” and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0051] Please refer to Figure 1 , Figure 1 The drug preparation test monitoring method in some embodiments of the present application is applied to a fume hood, and includes the steps of:

[0052] A1. Obtaining test information; the test information includes reagent information of reagents required for the test;

[0053] A2. Grouping the reagents according to the reagent information to obtain at least one reagent group;

[0054] A3. Displaying a placement area corresponding to each reagent group on the test bench according to the grouping result;

[0055] A4. Real-time monitoring of test operation, and judging whether there is a violation of operation based on the placement area and grouping results; the violation of operation includes a first violation of operation indicating that the reagent placement position is incorrect, and a second violation of operation indicating that the reagent bottle is not timely closed;

[0056] A5. When a violation of operation occurs, a warning is issued.

[0057] After grouping the reagents required for the test, the placement area corresponding to each reagent group is displayed on the test bench for the corresponding reagent group to be placed, so as to guide the operator to orderly classify and place each reagent, reduce the situation that the operator knocks down other reagents when taking the reagents due to disordered placement of the reagents, and timely issue a warning to remind the operator to correct (after being warned, the operator will pay more attention to the operation norm in the subsequent operation), which can effectively monitor the drug preparation test process and is conducive to reducing the occurrence of operation violations.

[0058] In some embodiments, the reagent information includes reagent identification information, volatility parameter and harmfulness parameter. The reagent identification information is information for identifying the reagent, which can be but is not limited to name, molecule or number, etc. The volatility parameter is a parameter quantitatively set in advance according to the volatility of the reagent (the specific setting rules can be determined according to actual needs), which is used to characterize the ease of reagent evaporation. The harmfulness parameter is a parameter quantitatively set in advance according to the toxicity, corrosivity, irritability and other characteristics of the reagent (the specific setting rules can be determined according to actual needs), which is used to characterize the harm degree of the reagent to the human body. The volatility parameter and the harmfulness parameter of the reagent can be obtained according to the reagent identification information.

[0059] The test information can be obtained by uploading by the test operator, or obtained by querying according to the test identification information. The test identification information can be but is not limited to test name or test number, etc. When querying the test information according to the test identification information, the test information can be obtained in a preset test information library (the test information library records the test information corresponding to various tests) according to the test identification information.

[0060] In some embodiments, all reagents in the laboratory can be pre-grouped (grouping can be performed according to actual needs) to obtain a plurality of first groups, and in step A2, the reagents required for the test belonging to the same first group are divided into the same reagent group. This way can realize fast grouping, but sometimes the reagents required for the test can be more and belong to different first groups, resulting in a large number of reagent groups and a large number of placement areas that need to be divided, which makes the reagent placement operation in the test process too cumbersome.

[0061] To this end, in some other embodiments, step A2 comprises:

[0062] According to the volatility parameter and the harmfulness parameter of each reagent, a hazard index of each reagent is calculated.

[0063] The reagents are grouped according to the hazard index.

[0064] The hazard of each reagent to human is quantitatively analyzed by the hazard index, and then the reagents are grouped according to the hazard index, so as to facilitate the subsequent setting of the placement area according to the hazard of each reagent group to human, so as to reduce the damage to human. In addition, reagents with similar hazard are grouped, which is conducive to avoiding the situation that the number of divided placement areas is too large, resulting in too cumbersome reagent placement operation in the test process.

[0065] In the case of the same harmfulness parameter, the greater the volatility parameter, the more volatile the reagent, and the higher the risk of causing harm to the operator. Therefore, compared with evaluating the harm of reagents to human only according to the harmfulness parameter, it is more scientific and reasonable to evaluate the harm of reagents to human by comprehensively considering the volatility parameter and the harmfulness parameter. Specifically, the sum or weighted sum (the specific weighting value can be set according to actual needs) of the volatility parameter and the harmfulness parameter can be calculated as the hazard index of the reagent, but it is not limited thereto.

[0066] Further, when the number of reagents in a reagent group is too large, the excessive reagents are placed in the same placement area, which is easy to cause other reagents to be knocked down when taking and placing reagents. Therefore, after the step of grouping the reagents according to the hazard index, the step of:

[0067] If there is a reagent group with a number of reagents exceeding a preset number threshold (which can be set according to actual needs), the reagent group with a number of reagents exceeding the preset number threshold is divided into at least two reagent groups, so that the number of reagents in all divided reagent groups does not exceed the preset number threshold.

[0068] In some embodiments, when the reagent group with a number of reagents exceeding the preset number threshold is divided into at least two reagent groups, the at least two reagent groups can be randomly divided.

[0069] In some other embodiments, when the reagent group with a number of reagents exceeding the preset number threshold is divided into at least two reagent groups, the reagents in the reagent group with a number of reagents exceeding the preset number threshold can be sorted according to the hazard index, and then the reagents in the reagent group are divided into at least two reagent groups according to the sorting result (for example, when divided into two groups, the first half of the reagents in the sorting is divided into a group, and the other half of the reagents is divided into another group).

[0070] In some embodiments, the test information further comprises the number of times each reagent is used; when the reagent groups whose number of reagents exceeds the preset number threshold are divided into at least two reagent groups, the reagents in the reagent groups whose number of reagents exceeds the preset number threshold can be sorted according to the number of times each reagent is used, and then the reagents in the reagent group are divided according to the sorting result to obtain at least two reagent groups. Thus, in the subsequent placement area position setting, the number of times each reagent is used can be considered, for example, under the same conditions, the placement area position of the reagent group with a larger average number of times of use can be closer to the operator, so as to facilitate the operator to take and place the reagents that need to be used multiple times, and improve the operation convenience.

[0071] Preferably, step A3 comprises:

[0072] A301. According to the hazard index of each reagent, the average hazard index of each reagent group is calculated;

[0073] A302. The size of the corresponding placement area is determined according to the number of reagents in each reagent group;

[0074] A303. The position of each placement area is determined according to the average hazard index of each reagent group, the size of the corresponding placement area, and the position of the preset operation area on the test bench;

[0075] A304. Each placement area is displayed on the test bench according to the position and size of each placement area.

[0076] The position of each placement area is determined according to the average hazard index of each reagent group and the position of the preset operation area, wherein the reagents with higher hazard can be placed at a position farther away from the preset operation area, thereby reducing the harm to the operator.

[0077] In step A301, the sum of the hazard indices of the reagents in the same reagent group is divided by the number of reagents to obtain the average hazard index of the reagent group.

[0078] The placement area can be, but is not limited to, a circular area, an elliptical area, a rectangular area, or other polygonal areas, etc. Preferably, the placement area is a rectangular area, which can more fully utilize the test bench surface space.

[0079] In step A302, the corresponding reference size is obtained in the reference size query table according to the number of reagents in each reagent group, as the size of the corresponding placement area.

[0080] In step A302, the size of the placement region can also be determined according to the preset inter-bottle interval L0 (which can be set according to actual needs) and the number of reagents in the reagent group; for example, the placement region is set as a rectangular region, and the following is performed:

[0081] If the number n of reagents in the reagent group does not exceed the preset first threshold m (which can be set according to actual needs), the length of the corresponding placement region is set as n*L0, and the width is set as L0.

[0082] If the number n of reagents in the reagent group exceeds the preset first threshold m and is an integer multiple of the first threshold m, the length of the corresponding placement region is set as n*L0, and the width is set as k*L0, where k is the multiple of n relative to m.

[0083] If the number n of reagents in the reagent group exceeds the preset first threshold m and is not an integer multiple of the first threshold m, the length of the corresponding placement region is set as n*L0, and the width is set as j*L0, where j is equal to the integer part of the quotient of n divided by m plus 1.

[0084] Thus, it can be ensured that the placement region has sufficient space to place the reagents in the reagent group, so that the reagent bottles of each reagent after placement can have sufficient spacing (at least L0 spacing) between them, thereby reducing the probability of encountering or even overturning other reagent bottles when taking and placing reagents.

[0085] The preset operation region is usually arranged at a position in the middle of the front side (the front side refers to the side close to the operator during the test) of the test bench, so as to facilitate the operator to perform test operation. The operation region is used to place test equipment to perform test operation, but is not limited thereto. In some embodiments, step A303 includes:

[0086] According to the size of the average hazard index, the reagent groups are sorted in descending order;

[0087] According to the sorting order, each reagent group is taken as a target group in turn, and the following is performed:

[0088] A minimum circumscribed rectangular window of the placement region of the target group (if the placement region is a rectangular region, the minimum circumscribed rectangular window is actually the boundary of the placement region) is used to perform window scanning in a preset order (for example, from left to right and from back to front) on the test bench surface to search for a first region that can place the minimum circumscribed rectangular window and does not interfere with the placement regions with determined positions and the operation region.

[0089] From the searched placement positions, a first region farthest from the placement region is selected as a target region, and the placement region of the target group is arranged at the target region (specifically, the center of the placement region of the target group is made to coincide with the center of the target region).

[0090] Thus, the higher the hazard of the reagent group, the farther the placement area from the operation area, and the lower the harm to the operator.

[0091] Preferably, after the reagent groups are sorted in descending order according to the average hazard index, the following step is performed:

[0092] If the difference between the average hazard indexes of two reagent groups sorted adjacently is less than a preset difference threshold (which can be set according to actual needs), the average number of uses of the reagents in each of the two reagent groups is calculated (the average number of uses of the reagents in each reagent group is obtained by dividing the sum of the number of uses of the reagents in the reagent group by the number of reagents), and the sorting of the reagent group with the smaller average number of uses is adjusted to be before the sorting of the reagent group with the larger average number of uses.

[0093] For example, if the difference between the average hazard indexes of the reagent group A sorted at the i-th and the reagent group B sorted at the i+1-th is less than the preset difference threshold, if the average number of uses of the reagents in the reagent group A is not greater than the average number of uses of the reagents in the reagent group B, the sorting of the reagent group A is kept as the i-th and the sorting of the reagent group B is kept as the i+1-th, if the average number of uses of the reagents in the reagent group A is greater than the average number of uses of the reagents in the reagent group B, the sorting of the reagent group A is adjusted to the i+1-th and the sorting of the reagent group B is adjusted to the i-th.

[0094] Thus, under similar hazard levels, the placement area of the reagent group with a larger average number of uses is closer to the operator, so as to facilitate the operator to take and place the reagents that need to be used multiple times, and improve the operation convenience.

[0095] In step A304, the placement areas can be displayed on the test bench by projection, lighting of different positions of the test bench, or other ways. For example, in some embodiments, the step of displaying the placement areas on the test bench comprises:

[0096] The placement areas are displayed by an LED array on the test bench.

[0097] That is, the test bench is provided with an array of LED lights, and the display of the placement areas is realized by lighting the LED lights at corresponding positions, so as to visually guide the operator to place the reagents. In the display, only the LED lights at the edges of the placement areas can be lit, or all the LED lights in the placement areas can be lit, or the LED lights at the edges of the placement areas are lit and the numbers of the placement areas are displayed by the LED lights inside the placement areas. Different colors can be displayed for different placement areas to facilitate the operator to distinguish the placement areas.

[0098] In some preferred embodiments, after step A3 and before step A4, the following step is further included:

[0099] The display displays the grouping results of the reagents and the corresponding relationship information between each reagent group and each placement area (the corresponding relationship information can be the color or code correspondence between each reagent group and each placement area).

[0100] In order to facilitate the operator to place the reagents according to the content displayed by the display.

[0101] Specifically, step A4 comprises:

[0102] A401. Real-time acquisition of video information of the test bench;

[0103] A402. Analyzing the video information based on an image analysis method to obtain the real-time placement position of each reagent;

[0104] A403. If the real-time placement position of at least one reagent is not in the corresponding placement area, it is determined that a first rule violation operation condition indicating that the reagent placement position is incorrect occurs.

[0105] In fact, the corresponding mark can be previously set on the reagent bottle cap of each reagent, and the real-time placement position of the corresponding reagent is obtained by recognizing the mark.

[0106] Further, step A4 further comprises:

[0107] A404. Analyzing the video information based on an image analysis method to obtain the opening time of the reagent bottle of each reagent;

[0108] A405. According to the volatility parameter and the harmfulness parameter of each reagent, the opening upper limit time of the reagent bottle of each reagent is obtained;

[0109] A406. If the opening time of the reagent bottle of at least one reagent exceeds the corresponding opening upper limit time, it is determined that a second rule violation operation condition indicating that the reagent bottle is not timely closed occurs.

[0110] Among them, one reagent in the laboratory (which can be selected according to actual needs) can be determined as a reference reagent in advance, and the volatility parameter and the harmfulness parameter of the reference reagent are taken as the reference volatility parameter and the reference harmfulness parameter, and the opening upper limit time of the reference reagent is set as the reference opening upper limit time in advance. In step A405, the ratio of the volatility parameter of each reagent to the reference volatility parameter is calculated, which is denoted as the first ratio, the ratio of the harmfulness parameter of each reagent to the reference harmfulness parameter is calculated, which is denoted as the second ratio, then the adjustment coefficient is calculated according to the first ratio and the second ratio, and finally the adjustment coefficient is multiplied by the reference opening upper limit time to obtain the opening upper limit time of the reagent bottle of each reagent. When calculating the adjustment coefficient according to the first ratio and the second ratio, the following formula can be used for calculation, but it is not limited thereto:

[0111] ;

[0112] wherein, is an adjustment coefficient, , , are all preset parameters (which can be set according to actual needs), is a first ratio, is a second ratio, is a preset opening time threshold value (which can be set according to actual needs).

[0113] Further, step A5 comprises:

[0114] if the first violation operation condition occurs, a first warning signal requiring correct placement of the reagent is sent out;

[0115] if the second violation operation condition occurs, a second warning signal requiring timely closing of the reagent bottle is sent out.

[0116] For example, the first warning signal and the second warning signal can include at least one of an acoustic signal, a light signal, and a text signal.

[0117] In some embodiments, the pharmaceutical preparation test monitoring method further comprises a step of:

[0118] adjusting the power of the air suction device of the fume hood according to the maximum value of the hazard index of the reagent required to be used in the test.

[0119] Thus, while ensuring that harmful waste gas can be effectively adsorbed, electricity is saved.

[0120] For example, a corresponding reference power can be set for different hazard index ranges in advance to form a power query table; the corresponding reference power is obtained in the power query table according to the maximum value of the hazard index of the reagent required to be used in the test, and then the power of the air suction device of the fume hood is adjusted to the reference power.

[0121] As can be seen from the above, the pharmaceutical preparation test monitoring method, by acquiring test information; the test information includes reagent information of a reagent required to be used in the test; grouping the reagents according to the reagent information to obtain at least one reagent group; displaying a placement area corresponding to each reagent group on the test bench according to the grouping result; monitoring the test operation condition in real time, and judging whether a violation operation condition occurs based on the placement area and the grouping result; the violation operation condition includes a first violation operation condition indicating that the reagent is placed in an incorrect position and a second violation operation condition indicating that the reagent bottle is not timely closed; when the violation operation condition occurs, a warning is sent out; thus, the pharmaceutical preparation test process can be effectively monitored, and it is beneficial to reduce the occurrence of operation violations.
