Figure 5 As shown, the slot section 1 is in communication with the annular disc slot 25, and the slot section 2 is used to insert the sampling cannula 105, and the slot section 1 and the slot section 2 are in communication.

[0033] A plurality of waste liquid tanks 27 are provided in the positioning plate 21, such as Fig.11As shown, a plurality of waste liquid tanks 27 are arranged in a cross shape between a plurality of slots 24, the waste liquid tank 27 is communicated with the annular disc slot 25, a waste liquid tank 29 is provided at the bottom of the positioning disk 21, the number of the waste liquid tanks 29 and the waste liquid tank 27 is set to be consistent, the waste liquid tank 1 27 is communicated with the waste liquid tank 29, the bottom of the waste liquid tank 29 is sealed with a waste liquid bottle 210, the inner cavity of the waste liquid tank 1 27 is fixedly installed with a support ring 28, wherein the sealed installation method of the waste liquid tank 29 and the waste liquid bottle 210 includes a threaded connection, and since the installation methods are all sealed by a sealing ring, when liquid is injected, the air pressure in the chamber will expand, so in order to improve the convenience of injecting liquid, the waste liquid bottle 210 can be placed in the waste liquid tank 29. Select elastic and expandable rubber material, similar to an air bag, which is only used to store some waste liquid, and the amount will be very small, so it does not affect the use; when injecting liquid, the waste liquid bottle 210 itself can expand, and when the inserted pipeline is pulled out, the squeezed gas can be discharged through the waste liquid tank 27, and at the same time, a one-way valve can be installed on the top of the waste liquid bottle 210, so that liquid and gas can only enter the inner cavity of the waste liquid bottle 210. When it expands to a certain extent, the waste liquid bottle 210 is removed through a threaded connection, and then the one-way valve installed on the top of the waste liquid bottle 210 is removed or the valve cap is opened to pour out the liquid in the waste liquid bottle 210; in addition, sealing rubber rings can be set at both ends of the separation ring 26 and the support ring 28 to improve the sealing of the corresponding pipeline insertion; The interior of the positioning plate 21 is provided with an inclined groove 211, and the inclined groove 211 is connected to the slot section 1 of the slot 24. Figure 6 As shown, the bottom outlet position of the inclined groove 211 is aligned with the push groove 410, the inner cavity of the inclined groove 211 is slidably connected with an elastic steel bar 212, and the middle of the inner cavity of the inclined groove 211 is connected with a middle groove 213, and the middle groove 213 is arranged inside the positioning plate 21, and the inner cavity of the middle groove 213 is fixedly installed with an elastic strip 214, and the elastic strip 214 is used to position the elastic steel strip 212 so that the elastic steel strip 212 is suspended in the inner cavity of the inclined groove 211, and the top of the elastic steel strip 212 is fixedly installed with a pressing end 215, which is used in actual use. The elastic steel bar 212 is pressed by the pressing end 215, and the elastic steel bar 212 is pushed to the inner cavity of the push groove 410. The deformation of the elastic steel bar 212 is used to push the drainage tube sleeve 48 to shift to the inner cavity of the annular disc groove 25. At this time, the liquid collection tube 42 is rotated to make the drainage tube 2 44 and the drainage tube sleeve 48 offset to the cavity of the slot 24 or the waste liquid tank 1 27, thereby forming an effect of changing the position of the insertion port. Finally, the pressing end 215 is released, and the elastic force of the elastic bar 214 is used to pull the elastic steel bar 212 back to the inner cavity of the inclined groove 211.

[0034] Regarding the above scheme, it should be noted that the multiple sampling tubes 101 are stretched and wound in the card slot 1 22 and the card slot 2 32, and the magnetic attraction strip 103 is used to form a magnetic attraction fixing effect.

The liquid in the discharge tube 1 46 enters the chambers of the sampling tube 101 and the sampling cannula 105 through the discharge tube 2 44 and the discharge tube sleeve 48. After the infusion is completed, the sealing cap 104 without the one-way exhaust valve 106 can be replaced for sealing; When switching to infuse other sampling tubes 101, press the pressing end 215 to insert the elastic steel bar 212 into the chamber of the push groove 410, and push the drain tube sleeve 48 to retract to the outside of the drain tube 2 44, that is, to retract the drain tube sleeve 48 to the position of the annular disc groove 25, and then rotate the liquid collection tube 42 to insert the drain tube sleeve 48 into the next slot 24 or the waste liquid tank 1 27, wherein the waste liquid tank 1 27 is used to store the waste liquid in each pipeline of the suction pump 41, and whether to infuse can be selected according to actual needs; After all the infusions are completed, all the sampling tubes 101 can be removed at the same time, and the two magnetic adsorption strips 103 can be pulled apart, so that all the sampling tubes 101 can be spread out in a plane, which is convenient for overall comparison, and finally the measurement and detection can be achieved through the scale on the surface of the sampling tube 101; in addition, the outer wall of the sampling tube 101 can be made of transparent material, which is conducive to observing the scale.
