However, since the types of sensors that can sense whether the laser light pins 800 are taken away from the needle storage box 3 are numerous, they are not limited to the above types.

The history recording module 473 records all the selection signals sent by the control host 900, and records the selection of the selection module 472 to the The light needle data of each of the laser light pins 800 of the needle position 411, and the time of generation of the received needle signals output by the light needle taking sensing unit 49 to correspondingly generate a light needle use recording file, the light The needle uses the log file to allow the control host 900 to wire the read output.

When the optical needle identification system of the present invention is used, the medical staff can first insert the laser light needles 800 that are intended to be used in the needle slots 30 of the needle storage box 3, and then attach and attach the needle storage box 3 to the needle needle box 3 The driving unit 43 drives the cover 42 to the base 41. Then, the power switch 461 (shown in FIG. 2) can be turned on to energize the entire needle selecting device 4.

After the needle selection device 4 is energized, the scan recognition module 471 first performs scan recognition of the laser pointer 800.

In this embodiment, the laser light pins 800 are disposed through the needle segment 802 for image recognition, but in practice, the laser light pins 800 can also pass through the needle segments. The geometric shape of the needle portion of the 802 is used for identification, for example, the needle portion is designed to be tapered, square, wedge-shaped, etc., at this time, the light needle recognition sensing unit 44 can be changed to take the needle of the needle segment 802. The part image is used for analysis and recognition by the scan recognition module 471. In addition, when the identification mark 803 is a one-dimensional bar code type, the optical pin recognition sensing unit 44 can be changed to scan the identification tag 803 that senses the one-dimensional bar code pattern, and output a sensing mode of the light and dark electric signal type. The type of signal.

Moreover, when the identification design of the laser light pins 800 is set in the joint segment 801, for example, the joint segment 801 is provided with an O-shaped gasket of a different color configuration that can be identified, or the joint segment 801 is different. The color representation, for example, the anode dyeing of different colors, at this time, the optical needle recognition sensing unit 44 can be modified to be exposed above the base 41, so that the optical needle recognition sensing unit 44 can sense the connector segments 801 for output. The sensing signal of the image signal type or the spectral signal type is used for analyzing and recognizing the scanning identification module 471 through the color identification mode.

Referring to FIG. 3 and FIG. 8 , in the implementation, the needle slots 30 of the needle storage box 3 are not required to provide the needle opening section 301, and the joint section 801 of the laser light needles 800 can be directly exposed. Above the top surface of the needle storage box 3, the shape of the needle opening 420 of the cover 42 is designed to conform to the shape of the laser phone 901.

As shown in FIG. 9, the second embodiment of the optical needle recognition system of the present invention differs from the first embodiment in the design of the control unit 47, and the optical needle taking sensing unit is not provided in the embodiment. For convenience of explanation, only the differences between the present embodiment and the first embodiment will be described below.

In this embodiment, the control unit 47 further includes a timing module 474. The timing module 474 can control the driving unit 43 to transfer the storage box 3 to the selected needle. When the light-emitting needle 800 is transferred to the needle-receiving position 411, a needle-taking time is started, and after the needle-taking time is over, a needle-taking determination signal is issued, and the needle-selecting module 472 is triggered by the needle-taking signal. And the drive unit 43 is again controlled to drive the needle storage box 3 to transfer the needle slot 30 of the selected laser light needle 800 to the sensing position of the light needle recognition sensing unit 44. The sensing unit 44 is triggered by the needle determining signal, and the sensing output is a sensing signal corresponding to the selected needle slot 30 of the selected laser light needle 800. The scan identification module 471 analyzes The sensing signal is used to determine whether the selected laser light needle 800 is still present in the needle slot 30, and when it is determined that the laser light needle 800 has not been selected, a needle signal is generated, and the signal is determined. When the laser light needle 800 is not removed, an untaken signal is generated.

Then, the needle selection module 472 is triggered by the picked needle signal and the untaken needle signal, and the driving unit 43 is controlled to transfer the needle storage box 3 to accommodate the selected laser light needle 800. The needle groove 30 is moved back to the needle taking position 411. In addition, the timing module 474 is triggered by the unacquired signal, and the needle selection signal is sent after the time of the needle is separated.

Through the above design, the history recording module 473 can also record and establish the optical needle usage record according to the generated time of the received needle signal and the untaken signal.

In summary, the structural design of the needle storage box 3 and the needle selection device 4 can be used to automatically and quickly select the laser light needle 800, which can completely improve various shortcomings of the current manual selection of the laser light needle 800.
