Description of the embodiments
Advantages of the invention will be described in detail below with reference to the drawings and the detailed description.
Referring to fig. 1, a block diagram of a sample information entry device according to a preferred embodiment of the present invention is shown. As can be seen from the figure, the sample information input device provided in this embodiment mainly includes: the bar code instrument 1 and the sample support 2, wherein the bar code instrument 1 comprises a code reading window 11, the sample support 2 is arranged relative to the code reading window 11 on the bar code instrument 1, namely, the sample support 2 is arranged facing to one surface of the bar code instrument 1, which contains the code reading window 11, so that the bar code instrument 1 can read bar code information on a test tube placed on the sample support 2 through the code reading window 11.
As can be seen in fig. 1, more specifically, the sample holder 2 includes a sample holder base 21 and a sample holder frame 22 mounted on the sample holder base 21. The sample holder base 21 supports the sample frame 22.
Reference is now made to fig. 2, which is an exploded view of a preferred sample entry device according to fig. 1. As can be seen from the figure, in this embodiment, the sample holder base 21 includes a bottom plate 211, a surface of the bottom plate 211 facing the sample holder frame 22 is a first surface 2111, and the first surface 2111 includes at least two parallel guide strips 212; meanwhile, on the first surface 2111, one end, which is vertically close to the guide bar 212 and far away from the bar code instrument 1, also comprises a baffle 213; in this embodiment, the opposite side of the bottom plate 211 to the first side 2111 is a second side 2112, and a detection plate 214 is mounted on the second side 2112.
In view of the above design of the present embodiment, a guide rail 215 is formed between the parallel guide bars 212 on the bottom plate 211, so that the sample holder frame 22 can slide along the guide rail 215 and stop at the baffle 213 after being mounted in the guide rail 215. Thus, the sample holder frame 22 can be pushed to slide in the guide rail 215 on the sample holder base 21, so that the test tube 4 placed in the sample holder frame 22 can sequentially pass through the code reading window 11 on the bar code meter 1, and the bar code information on the test tube can be read.
In addition, with continued reference to FIG. 2, it can be seen that the sample holder frame 22 has at least one tube slot 222 therein for receiving a test tube 4. In addition, a first hollowed-out portion 2221 is disposed on a side of the test tube slot 222 facing the bar code meter 1. Therefore, the test tube can be clamped in the test tube groove 222, the stable placement of the test tube 4 is ensured, the sample in the test tube is prevented from leaking in the moving process of the sample support frame 22, and meanwhile, when the sample support frame 22 slides on the sample support base 21 and passes through the code reading window 11 of the bar code instrument 1, the bar code instrument 1 can sequentially read bar code information on the test tube 4 through the first hollowed-out part 2221.
In addition, the present embodiment is also advantageous in that the bottom of the sample holder frame 22 is provided with a strong magnet 221. Therefore, when the sample support frame 22 slides along the guide rail 215 on the sample support base 21, the detection board 214 of the sample support base 21 can sense the Jiang Citie at the bottom of the sample support frame 22 and generate a first electric signal, and the barcode instrument 1 can receive the first electric signal, so that the barcode scanning function module of the barcode instrument is started according to the first electric signal, and the barcode instrument 1 can read the barcode information on the test tube 4 through the first hollowed-out portion 2221 on the test tube slot 222. Therefore, the technical effect of automatically reading the bar code information on the test tube can be realized by using a simple device and simple operation.
Preferably, in the present embodiment, a hall sensor is disposed on the detection plate 214, and when the sample support frame 22 slides along the guide rail 215, the strong magnet 221 on the sample support frame 22 is driven to move; when the strong magnet 221 reaches the upper portion of the hall sensor, in this embodiment, the sample support frame 22 is considered to reach the code scanning position, the hall sensor can sense the magnetic field of the strong magnet 221, correspondingly generate a first electric signal, send the first electric signal to the outside, and after the barcode instrument 1 receives the first electric signal, start the corresponding code scanning module in the barcode instrument 1 to scan the barcode information on the test tube 4 in the current code scanning position.
With continued reference to fig. 1, in the preferred embodiment, the barcode apparatus 1 further includes a light source (not shown), which is disposed in the code reading window 11 of the barcode apparatus 1; correspondingly, the sample support further comprises an optical fiber sensor 3, and the optical fiber sensor 3 is arranged on the sample support base 21 and is arranged at one end of the sample support base 21 far away from the light source. And the line between the light source and the optical fiber sensor 3 is perpendicular to the guide rail 215 on the sample holder base 21. Meanwhile, referring to fig. 3, an exploded view of a preferred sample holder frame according to fig. 1 is shown. As can be seen from the figure, in the present embodiment, a second hollow 2222 is provided on the side wall of the side of the sample holder frame 22, which is far from the bar code instrument 1, of the test tube slot 222. When the sample support frame 22 slides along the guide rail 215, and the test tube slot 222 moves to the connection line between the light source of the code reading window 11 of the bar code instrument 1 and the optical fiber sensor 3, if the test tube is placed in the test tube slot 222, the test tube will block the light emitted by the light source in the code reading window 11 of the bar code instrument 1, and the optical fiber sensor 3 will generate a corresponding second electric signal; if there is no cuvette in the cuvette slot 222, the light generated by the light source will be irradiated onto the optical fiber sensor 3, and the optical fiber sensor 3 generates a third variable electrical signal. In this embodiment, the second signal or the third signal may be 0 or 1 readable by a computer, so that the sample input device in this embodiment can know whether the corresponding position on the sample support 2 has the test tube according to the electrical signal. Therefore, the accuracy of reading the bar code by the bar code meter 1 can be further judged by combining the bar code information on the test tube read by the bar code meter 1, for example, when the bar code meter 1 does not read the bar code information, whether no test tube exists at the position or the bar code meter 1 is in error, and the bar code information on the existing test tube is not successfully read.
Preferably, in this embodiment, the optical fiber sensor 3 may also receive the first electrical signal generated by the sensing plate 214 sensing the strong magnet 221, and activate the optical fiber sensor according to the first electrical signal, so as to sense the light emitted by the light source in the barcode instrument 1, and determine whether the test tube 4 is present on the sample holder 2.

Thus, when the sample holder frame 22 slides to the bottom of the guide rail 215 and abuts against the baffle 213, the guide beads 2131 on the baffle 213 are clamped into the clamping holes of the sample holder frame 22. Therefore, the sample support frame 22 can be ensured to be accurately and stably fixed at the baffle 213 of the sample support base 21, and when a plurality of sample support frames 22 exist on the sample support base 21 at the same time, the sample support frames cannot be mutually influenced.

Thus, when the sample holder frame 22 slides to the bottom of the guide rail and the guide beads 2131 are engaged with the engaging holes, the guide beads 2131 press the switch of the indicator lamp to turn on the indicator lamp. And, the light emitted from the indicator lamp is guided by the light guide column 2151 and then emitted outwards. Therefore, whether the test tube placed in the sample holder frame 22 completes information recording in this embodiment can be determined according to whether the light is emitted from the light guide column 2151.
