DESCRIPTION OF THE EMBODIMENTS

[0015] As shown in FIG. 1 and FIG. 2, a sample adding system for automatically adding sputum digestion liquid of the present disclosure includes a weighing device 1 with a weight sensor and a sample adding device. The sample adding device includes a sputum digestion liquid reagent bottle 2. A sample adding tube 3 has a liquid inlet going deep into the sputum digestion liquid reagent bottle 2, and a liquid outlet extending to a position above the weighing device 1. A sample adding needle 4 is connected to the liquid outlet of the sample adding tube 3, and the sample adding needle 6 may adopt a steel needle or a Tip head to ensure that an addition amount is more accurate. The sample adding tube is equipped with a quantitative sample adding pump 5. A signal output end of the weight sensor is electrically connected to a signal input end of a single-chip microcomputer, and a control output end of the single-chip microcomputer is electrically connected to a control input end of the quantitative sample adding pump 5.

[0016] In the actual implementation, the weighing device 1 can adopt a balance, and certainly, other weighing platforms can also be used. The quantitative sample adding pump 5 can adopt a plunger pump, a peristaltic pump, a gear pump or a quantitative valve.

[0017] When in use, a cup 6 containing the sputum is placed on the weighing device 1. The shape, size and color of the cup 6 can be selected freely, and the weighing device 1 is configured for weighing a total weight of the cup 6 and the sputum contained in the cup 6. The weight sensor on the weighing device 1 can directly send feedback of the total mass of the weighed cup 6 (including sputum) to the single-chip microcomputer, and the single-chip computer obtains a mass of the sputum through calculation. Through calculation, the sputum mass corresponds to a corresponding addition amount of sputum digestion liquid. The quantitative sample adding pump 5 is controlled by the single-chip microcomputer to add sputum digestion liquid according to the calculated addition amount of sputum digestion liquid, thereby accurately completing quantitative sample addition of sputum digestion liquid, and realizing standardization and automation of addition amount of sputum digestion liquid.

[0018] The disclosure realizes the standardization of addition of the sputum digestion liquid by weighing the sputum, so that the bacteria in the sputum are homogenized better, and the culture positive rate of the actual pathogenic bacteria is greatly improved.
