The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1, in a preferred embodiment of the present invention, a test tube barcode scanning device 100 is used to scan barcodes of test tubes on a test tube rack, so as to correlate information of each test tube with patient information in a LIS system of a hospital, and facilitate automatically transmitting test results of samples in the test tube to the LIS system of the hospital after detection. In this embodiment, the test tube barcode scanner 100 is communicatively connected to a fully automatic nucleic acid extractor, and is configured to, after analysis and detection by the fully automatic nucleic acid extractor, correlate the detection result, each test tube information, and patient information, and then transmit the correlated detection result, each test tube information, and patient information to the LIS system of the hospital. It will be appreciated that in other embodiments, the tube barcode scanner 100 is also used in connection with other analytical instruments, such as blood analyzers, etc., without limitation.
The test tube barcode scanning device 100 includes a base 10, a test tube rack 30, an in-place switch (not shown), and a scanner 70. The base 10 is used to provide a mounting base for the entire test tube barcode scanning device 100; the test tube rack 30 is disposed on the base 10, and is used for placing test tubes, so that a downstream instrument (such as a fully automatic nucleic acid extractor in this embodiment) can detect and analyze samples in the test tubes; the in-place switch is used for accurately positioning the test tube rack 30 when being placed on the base 10 so as to facilitate the accurate scanning of the scanner 70 and the related operation performed after the test tube rack 30 is accurately positioned; the scanner 50 is used for acquiring and storing information of the test tube rack 30 and the test tube, so that the acquired information can be associated with the LIS of the hospital, and sample information and patient information can be accurately corresponding.
Referring to fig. 2 and 3, the base 10 is generally L-shaped and includes a bottom plate 11 and a side plate 13 protruding above the bottom plate 11. The bottom plate 11 has a generally rectangular plate shape having short sides and long sides, and includes an upper surface 110 facing the user and a lower surface (not shown) facing away from the upper surface 110.
The test tube rack 30 is placed on the upper surface 110 of the base 10 and can reciprocate in a first direction relative to the base 10 under the action of external force.
Specifically, the test tube rack 30 includes a main body 31, a back plate 33, and a plurality of engaging portions 35. The main body 31 is substantially rectangular parallelepiped and includes a front surface facing the scanner 70 in the first direction and a back surface facing away from the scanner 70. Meanwhile, the main body 31 is provided with a plurality of receiving holes 310 for receiving test tubes. The plurality of receiving holes 310 are arranged at intervals along the moving direction (i.e., the first direction) of the test tube rack 30 with respect to the base 10, so that the scanner 50 can scan the bar code on the test tube received in the receiving holes 310 along the first direction. It will be appreciated that in other embodiments, the arrangement of the receiving holes 310 may be as desired and is not limited herein.
Wherein, the main body 31 faces the front of the scanner 70 and is provided with a notch 312 corresponding to each accommodating hole 310, so that the bar code adhered to the test tube is exposed, thereby facilitating the scanning operation of the scanner 70. Meanwhile, a barcode pasting area 314 is reserved on one side of the main body 31 facing the front of the scanner 70 and located at each notch 312, and barcodes for reflecting the position information of each test tube are sequentially pasted in the barcode pasting area 314.
When the scanner 70 scans, the bar codes on the test tubes in the plurality of accommodating holes 310 on each test tube rack 30 can be scanned to obtain sample information, and meanwhile, the bar codes in the bar code pasting area 314 on the scanning test tube rack 30 can be scanned to obtain the position information of each test tube, so that the position information of each test tube, the sample information in the test tube and the final detection result are finally correlated with the patient information in the LIS system of the hospital.
The back plate 33 is disposed on the back of the main body 31 opposite to the notch 312 and protrudes from the opening end of the accommodating hole 310, and the plurality of clamping portions 35 are disposed on the surface of the back plate 33 facing the accommodating hole 310 in one-to-one correspondence with the accommodating hole 310, for clamping the test tube cover on the test tube.
In this embodiment, each of the locking portions 35 is an L-shaped hook disposed on the back plate 33, and the opening direction of the L-shaped hook faces the corresponding receiving hole 310. When the test tube is placed in the accommodating hole 310, the test tube cover can be clamped in the opening of the L-shaped clamping hook, so that the full-automatic nucleic acid extractor is convenient for extracting samples in the test tube, and interference to the extraction operation caused by falling of the test tube cover is avoided.
Further, the test tube rack 30 further includes an elastic pressing member 37 (only one of the accommodating holes 310 is shown in fig. 3 as the elastic pressing member 37), one end of the elastic pressing member 37 is fixed to the wall of the accommodating hole 310, and the other end of the elastic pressing member extends into the accommodating hole 310 in a radially elastically deformable manner along the accommodating hole 310. Thus, when the test tube with larger tube diameter is placed in the accommodating hole 310, the test tube can squeeze the elastic pressing piece 37 to generate larger deformation so as to give way for the test tube with larger tube diameter; when the test tube with smaller tube diameter is placed in the accommodating hole 310, the test tube can extrude the elastic pressing piece 37 to generate smaller deformation even without deformation, and at the moment, the elastic pressing piece 37 can also be abutted against the outer tube wall of the test tube with smaller tube diameter to provide pre-pressing force for the test tube with smaller tube diameter so as to fix the test tube with smaller tube diameter. That is, by providing the elastic pressing member 37, the adaptability of the test tube rack 30 is improved, so that it is possible to place test tubes of various appropriate tube diameters.
In this embodiment, the elastic pressing member 37 is a spring plate with one end suspended and extending into the accommodating hole 310. It should be appreciated that in other embodiments, the elastic pressing member 37 may be an elastic pad or other deformable elastic structure disposed on the inner wall of the accommodating hole 310, which is not limited herein.
Further, the test tube rack 30 further comprises a handle 39 protruding from the tail end of the main body 31, so as to be convenient for an operator to hold. The tail end mentioned above, that is, when the test tube rack 30 is placed on the base 10 along the first direction, first enters one end of the base 10 as the head end, and finally enters the base 10 as the tail end.
Still further, the bottom plate 11 further includes guide ribs 114 protruding from a surface of the bottom plate 11 facing the side plate 13 (i.e., the upper surface 110). The guide rib 114 extends lengthwise in a first direction (in this embodiment, the longitudinal direction of the bottom plate 11, i.e., the moving direction of the rack 30) for guiding the rack 30 into and out of the base 10.
In this embodiment, the guide ribs 114 include a plurality of guide ribs 114 arranged on the upper surface 110 at intervals along the vertical first direction, and a guide groove 1141 for accommodating the test tube rack 30 is defined between two adjacent guide ribs 114. Correspondingly, the test tube racks 30 include a plurality of test tube racks 30 installed at intervals along the vertical first direction, and the main body 31 of each test tube rack 30 is provided with a guide groove 312 at a position corresponding to the guide rib 114, so that the guide rib 114 is embedded in the guide groove 312 when the test tube racks 30 are placed on the base 10, the test tube racks 30 are moved along the guide rib 114, and the test tube racks 30 are prevented from shifting in the moving process.
In this embodiment, each of the guide ribs 114 has a substantially inverted L-shaped cross section, and each adjacent two of the guide ribs 114 are disposed in a manner facing each other. The test tube rack 30 includes 6 test tube racks sequentially arranged along the short side direction of the bottom plate 11, and each test tube rack 30 has guide grooves 312 formed on two sides (i.e., two sides in the width direction) of the main body 31 perpendicular to the first direction, and each guide groove 312 is in snap fit with the edge of the corresponding guide rib 114. It will be appreciated that in other embodiments, the number, shape, and orientation of the guide ribs 114 may be varied as desired and are not limited in this regard.
In one embodiment, the in-place switch includes a plurality of in-place switches, each of which is mounted on the base 10 and is located on the moving path of the test tube rack 30. The in-place switch generates an in-place signal after being triggered by the test tube rack 30, and the scanner 70 performs a related action according to the in-place signal. Wherein the relevant actions performed by the scanner 70 include at least one of start-up, scan, data save, and data upload.
In this embodiment, a plurality of assembly grooves 130 are formed in the surface of the side plate 13 facing the bottom plate 11 in the direction parallel to the spacing direction of the plurality of test tube racks 30, and each in-place switch is installed in each assembly groove 130 so as to correspond to each test tube rack 30 one by one. Meanwhile, each in-place switch is located at the end point of the moving path of the corresponding test tube rack 30 entering the base 10, so that when the test tube rack 30 completely enters the base 10, the head end of the test tube rack 30 triggers the in-place switch opposite to the head end of the test tube rack 30, and the scanner 70 is controlled to execute related actions according to the in-place signals.
Further, the test tube barcode scanning device 100 includes an in-place prompter 80, where the in-place prompter 80 is connected to an in-place switch, and is used for generating a prompt message according to an in-place signal. That is, when the head end of the test tube rack 30 triggers the in-place switch, the in-place prompter 80 generates a prompt message to remind an operator that the test tube rack 30 is in place accurately. The prompt information may be light, sound, or the like, which is not limited herein.
Still further, the cuvette barcode scanning device 100 comprises an inductive switch 90. The inductive switch 90 is disposed on the surface (i.e. the upper surface 110) of the bottom plate 11 facing the side plate 13 and is located at the beginning of the moving path of the test tube rack 30 when the test tube rack 30 enters the base 10, so that when the test tube rack 30 enters the base 10, the inductive switch 90 is triggered and generates starting information to control the scanner 70 to be turned on. In this embodiment, the test tube rack 30 is a metal rack structure, and the sensor switch 90 is a ceramic sensor switch. It should be appreciated that in other embodiments, the matching manner of the test tube rack 30 and the sensing switch 90 may be other manners, for example, the sensing switch 90 is a conventional mechanical switch, and the test tube rack 30 may trigger the sensing switch 90 during the moving process, which is not limited herein.
In this embodiment, when the test tube rack 30 enters the base 10 along the first direction, the head end of the test tube rack 30 triggers the inductive switch 90, and the inductive switch 90 generates the start information to control the scanner 70 to start and start the scanning operation. When the test tube rack 30 continues to move forward, the bar code on the test tube passing through the scanner 70 and the bar code in the bar code pasting area 314 on the test tube rack 30 are scanned and recorded until the test tube rack 30 completely enters the base 10, and the head end touches the in-place switch, the scanner 70 stops the scanning operation and saves and uploads the relevant information obtained by scanning, and the current scanning operation of the test tube rack 30 is ended. That is, the scanner 70 is turned on and starts scanning when receiving the start information, and the related actions performed by the scanner 70 when receiving the bit information are data saving and data uploading of the information acquired by scanning.
It will be appreciated that in other embodiments, the scanner 70 may also be movable in the first direction relative to the base 10, and the sensor switch 90 may generate the start information after being triggered, where the start information is only used to start the scanner 70, and the scanner 70 does not perform the scanning operation. When the test tube rack 30 completely enters the base 10 and the head end touches the in-place switch, the scanner 70 starts to move along the first direction relative to the base 10 according to the in-place information, so as to scan the bar codes in the bar code pasting area 314 on the test tube rack 30 and the bar codes on the test tubes one by one, and complete the acquisition, storage and uploading of the related information. That is, at this time, the relevant actions performed by the scanner 70 upon receiving the bit information are scanning, data saving, and data uploading.
Still further, the surface of the side plate 13 facing the bottom plate 11 is provided with a plurality of magnetic attraction pieces 136, and each magnetic attraction piece 136 is opposite to each test tube rack 30 for attracting the test tube rack 30 entering the base 10. Specifically, the number of the magnetic attraction pieces 136 corresponds to the number of the guide grooves 1141 one by one, that is, the projection of each magnetic attraction piece 136 relative to the bottom plate 11 falls into the corresponding guide groove 1141, so that when each test tube rack 30 enters the base 10 along the guide groove 1141 and falls into the magnetic force range of the magnetic attraction piece 136, the test tube rack 30 can be accelerated to move towards the direction close to the side plate 13 under the action of the adsorption force of the magnetic attraction piece 136, and is stably adsorbed with the magnetic attraction piece 136.
In this embodiment, the magnetic attraction member 136 is a magnet block disposed on the side plate 13, and the test tube rack 30 is a metal structure attracted to the magnetic attraction member 136. It should be understood that in other embodiments, the test tube rack 132 may be disposed with a surface corresponding to the magnetic attraction member 136 being a metal structure, which is not limited herein.
In one embodiment, the side plate 13 is provided with a fixing hole 138, and the fixing hole 138 penetrates the side plate 13 along the direction perpendicular to the bottom plate 11, so as to fix the test tube bar code scanner 100 on other test or support platforms.
In still another embodiment, the bottom surface of the bottom plate 11 is provided with a positioning groove (not shown), which is used for positioning and matching with a protrusion structure at a corresponding position on other equipment (e.g., an automatic nucleic acid extractor in the present embodiment) when the test tube barcode scanning device 100 is fixed on the other equipment.
In the test tube bar code scanning device 100, an in-place switch is arranged, so that when the test tube rack 30 is accurately positioned on the base 10, the scanner 70 is controlled to execute corresponding actions according to in-place information, such as starting scanning or saving after scanning, and the like, so that the error information obtained after the scanner 70 scans the test tube rack 30 which is not positioned is avoided, and the accuracy of the whole test information in the later stage is influenced.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
