Referring to fig. 4, 5, and 6, the steps of obtaining a donor wax block and a corresponding stained section include terminal reading of a first label of a donor wax block cassette used to embed the tissue sample; retrieving medical record information associated with the sample organization and associating the medical record information with the first label; the terminal reads a second label on a slice box for presenting the stained slice; associating the first label with the second label; and accumulating the donor wax blocks and the dyed sections to generate associated information.
With the above scheme, the first label may include donor wax block box information, specifically, may be storage location information of the donor wax block box, for example, the first label information may be "a 03 cabinet 01 zone 01 row 01 column"; the medical record information of the sample organization can comprise source attribution information such as patient name, age and the like; the second label information may include information on the location where the slide cassette is stored, and for example, the second label information may be "a 03 row 02 in the cabinet 02 area 02". The first label and the second label can be arranged in a bar code or a two-dimensional code form, and the surface packaging prevents the first label and the second label from being corroded when soaked. The medical record information of the sample organization can be pre-input into an information base. Specifically, when a worker prepares the donor wax block, the worker can scan the first label by holding a mobile phone and other terminal equipment, and then a corresponding interface can be popped up, wherein the information of each first label is different. The staff can know the organization medical record information embedded into the donor wax block in advance, then the staff can find the medical record information which is the same as the organization medical record information which is known in advance in the options of the interface through attribute screening, for example, screening is carried out through the name Zhang III, and the medical record information is input, so that each piece of medical record information corresponds to the corresponding first label, and information interconnection and binding are realized. When the terminal reads the second label, a corresponding selection interface is popped up, the first label is correlated with the second label by searching the information of the first label in the information base, namely, the medical record information, the first label information and the second label information are jointly bound, and the information is uploaded to the cloud server for recording and then is stored. When the staff needs to search for the dyed slices or donor wax blocks of corresponding patients, the one-to-one correspondence relationship between the donor wax block boxes and the slice boxes in the storage space can be realized by inputting the attributes in the medical record information at the terminal, and the accurate positioning is realized.
The storage space is provided in the form of a storage cabinet or in the form of a drawer 29 in a storage cabinet.
In the current preparation process, an offline recording mode is usually adopted, corresponding errors of the three are easy to occur due to negligence of workers and improper operation, and the situation that the search is not matched with the actual search due to human errors during the search occurs. The technical scheme has the technical problems of improving the preparation efficiency, the storage efficiency and the storage accuracy.
Referring to fig. 5, the steps of obtaining donor wax blocks and corresponding stained sections include:
receiving batch medical record information searching instructions;
and according to the medical record information searching instruction, generating a region set where the donor wax block and the dyed section to be acquired are located.
By adopting the scheme, in the actual preparation process, a plurality of groups of donor wax blocks and dyeing slices are required to be taken out in sequence, and because the taken donor wax blocks and the dyeing slices are not necessarily adjacent to each other in the storage position, the working personnel need to frequently take the donor wax blocks and the dyeing slices from different storage spaces, so that the material taking efficiency is greatly reduced. Above-mentioned scheme, through the case history information that will input in batches, can confirm the information of the donor wax piece box and the slice box of waiting to acquire, through match the information of the two with storage space's in the information bank information, can generate all the information of the donor wax piece box and the slice box of waiting to acquire in the same storage space in batches at the display interface, the staff passes through above-mentioned information, can once only get the donor wax piece box or the slice box in the same storage space completely, remove other storage spaces and draw materials again, sampling efficiency has been promoted. The reference of the region set can be preset, and a single cabinet can be used as a reference unit or each layer in the cabinet can be used as a reference unit according to the sizes of different storage spaces.
Referring to fig. 7, the step of generating a set of regions where the donor wax pieces, stained sections, are to be acquired comprises:
traversing all the area sets, and identifying the number attribute of the area sets;
and calling a set rule, and carrying out sampling sequence arrangement on the region set according to the set rule.
By adopting the scheme, the number attribute can be Arabic numbers or letters on numbers, the established rule can be that the numbers of the storage spaces are arranged from large to small or from small to large, and the layers can be arranged in the order of top, middle and bottom, for example, the displayed region sets are arranged in the order of "A01 cabinet 01 area 01 row 01 column", "A01 cabinet 01 area 02 row 01 column", "A01 cabinet 02 area 01 row 01 column", "A02 cabinet 02 area 02 row 01 column", and "A03 cabinet 03 area 02 row 01 column", because the actual storage spaces are also arranged in the order of the numbers, a worker can conveniently take out all the donor wax blocks and the dyeing slices at one time in the adjacent layers or the adjacent storage spaces without frequently switching different storage spaces, and the working efficiency is improved.
The step of generating the region set where the donor wax block and the stained section to be obtained are located comprises the following steps:
acquiring an extraction instruction;
traversing all the area sets, and identifying the number attribute of the area sets;
acquiring power device information corresponding to the serial number attribute in the area set;
the power device receives the server information to open the storage space for the donor wax blocks and/or stained sections to be removed.
By adopting the scheme, each storage space is provided with a power device capable of being automatically opened, such as a motor-driven power device or a hydraulic power device, the server can send an opening instruction to the cabinet body or the drawer 29 containing the region collection information after receiving the region collection information, the opened storage space for opening the storage space for storing the donor wax blocks and/or the dyeing slices to be taken out does not necessarily represent a cabinet door, and the storage space can also be in the forms of pulling the drawer 29 open, opening the upper cover and the like, at the moment, the corresponding storage space is opened without the comparison terminal by the staff one by one, the drawer 29 of the corresponding storage space can be opened in an automatic opening mode, and the staff can be closed after taking one drawer 29 each time until all the drawers are taken out. The scheme reduces human errors of workers and improves the working efficiency.
Fig. 6, 8-13 below illustrate a storage cabinet for storing wax blocks or shifting pieces, which includes a cabinet body including a side fixing plate 12 and a drawer connected to the side fixing plate 12; the drawer comprises a second power device 21 arranged inside and a containing device 22 connected with the second power device 21, wherein the containing device 22 can move under the action of the second power device 21.
