[0032] The following is a specific embodiment of the present application and further describes the technical scheme of the present application in combination with the drawings, but the present application is not limited to these embodiments.

[0033] Please refer to Figs. 1-3 The utility model discloses a liquid preparation tank with quick-mounting aseptic sensor interface, which comprises:

[0034] The tank body 100 is provided with a quick-mounting interface 200 on the side thereof, and the quick-mounting interface 200 is provided with a first connecting part 210 at the end away from the tank body 100, and the cross-sectional area of the first connecting part 210 is greater than that of the quick-mounting interface 200.

[0035] The detection assembly 300 comprises a mounting column 310, which is provided with a detection probe 350, and the mounting column 310 can extend into the quick-mounting interface 200 and make the detection probe 350 extend into the tank body 100; the mounting column 310 has an extending end and a connecting end opposite to each other, and the mounting column 310 can extend into the quick-mounting interface 200 along the direction from the connecting end to the extending end; the connecting end is provided with a second connecting part 320, and the cross-sectional area of the second connecting part 320 is greater than that of the mounting column 310.

[0036] The first connecting part 210 and the second connecting part 320 are connected through buckling, a first sealing ring is arranged between the first connecting part 210 and the second connecting part 320, and a second sealing ring 340 is arranged between the side of the mounting column 310 and the inner wall of the quick-mounting interface 200.

[0037] The application realizes the connection with the sensing probe through the quick-mounting interface 200 on the side of the tank body 100, and realizes the detection of the liquid medicine in the tank body 100. At the same time, through the design of the quick-mounting interface 200, the original scheme of detecting the liquid medicine through an external pipeline is replaced, which can effectively prevent the liquid medicine from remaining in the pipeline and avoid the pollution of the remaining liquid medicine to the newly stored liquid medicine.

[0038] Specifically, the mounting column 310 is arranged, and the second sealing ring 340 is arranged between the mounting column 310 and the quick-mounting interface, the mounting column 310 extends into the quick-mounting interface 200, so that the detection probe 350 is brought into the tank body 100 for detection, and when the mounting column 310 extends into the quick-mounting interface 200, the quick-mounting interface 200 can be filled to a great extent, so that the liquid medicine is prevented from entering the quick-mounting interface 200 in a large amount and too deep, and the pollution caused by the remaining liquid medicine is avoided.

[0039] It should be noted that even if a small part of the liquid medicine can enter the quick-mounting interface 200, it will only adhere to a shallow position of the extending end, and the remaining liquid medicine can be easily cleaned when the tank body 100 is cleaned, and the problem of liquid medicine remaining caused by the liquid medicine entering the quick-mounting interface 200 too deep and being unable to be cleaned.

[0040] Further, the second sealing ring 340 plays a role of isolating the drug solution, avoiding the drug solution from penetrating into the quick connector 200. The first sealing ring plays a role of secondary sealing, when the second sealing ring 340 fails, the first sealing ring can avoid the drug solution from flowing out from the quick connector 200; at the same time, due to the elasticity of the first sealing ring, when the buckle connects the first connecting part 210 and the second connecting part 320, the first sealing ring is pressed, so that the first sealing ring provides a certain pre-tightening force, so that the buckle can be tightly clamped and not easy to fall off, and the mounting column 310 is more stable and firm in connection with the quick connector 200.

[0041] Further, the first connecting part 210 and the second connecting part 320 each have a connecting surface and a back surface opposite to each other, and the first sealing ring is arranged between the two connecting surfaces.

[0042] The buckle is rotatably arranged on the back surface of the first connecting part 210 and / or the second connecting part 320.

[0043] Further, the buckle has an abutting part and a hinged part, the hinged part is hinged to one of the back surfaces, and the abutting part can abut against the other back surface.

[0044] Further, a limiting column is arranged on the back surface of the first connecting part 210 and / or the second connecting part 320, and the limiting column can abut against the abutting part and limit the rotation of the buckle.

[0045] Specifically, the hinged part of the buckle is rotatably connected to the back surface of the first connecting part 210 or the second connecting part 320, by rotating the buckle, the abutting part of the buckle passes over the limiting column and abuts against the limiting column, realizing the locking of the buckle, and further realizing the connection between the first connecting part 210 and the second connecting part 320.

[0046] Further, a first circular groove 321 is arranged at each of the connecting surfaces, and the first sealing ring can be simultaneously embedded in the two first circular grooves 321.

[0047] The first circular groove 321 is arranged at each of the connecting surfaces, so that at least part of the first sealing ring can be simultaneously embedded in the two first circular grooves 321, realizing the positioning of the first connecting part 210 and the second connecting part 320 while playing a sealing role.

[0048] Further, a second circular groove 330 is arranged on the side surface of the mounting column 310, and the second sealing ring 340 can be embedded in the second circular groove 330.

[0049] A second circular groove 330 is arranged to install a second sealing ring 340, which moves along with the mounting column 310. When the mounting column 310 extends into the quick connector 200, the second sealing ring 340 enters the quick connector 200 along with the mounting column 310 and is pressed by the inner wall of the quick connector 200, thereby avoiding the liquid medicine from extending into the quick connector 200.

[0050] Further, the second circular groove 330 is arranged at the side of the mounting column 310 and close to the extending end.

[0051] In particular, since the second circular groove 330 is arranged close to the extending end, the second sealing ring 340 is also arranged at this position, which can further reduce the depth of the liquid medicine entering the quick connector 200, and even completely avoid the liquid medicine from entering the quick connector 200, thereby eliminating the liquid medicine residue.

[0052] Further, the quick connector 200 is gradually inclined upward along the direction away from the tank body 100.

[0053] In particular, since the quick connector 200 is inclined upward, when the liquid medicine is cleaned, it can flow into the tank body 100 under the action of its own gravity, thereby reducing the residue; when the tank body 100 is cleaned, the cleaning liquid can enter the quick connector 200 and flow out of the quick connector 200 under the action of its own gravity, thereby removing the liquid medicine adhered to the inner wall of the quick connector 200, and achieving the dead angle-free cleaning of the residual liquid medicine.

[0054] Further, the tank body 100 has an arc-shaped bottom surface, the bottom surface is connected with the side surface of the tank body 100, and the quick connector 200 is arranged at the side surface of the tank body 100 and at the end facing the bottom surface.

[0055] Further, the length of the mounting column 310 is greater than or equal to the length of the quick connector 200.

[0056] When the length of the mounting column 310 is greater than the length of the quick connector 200, the mounting column 310 can extend out of the quick connector 200 and extend into the tank body 100, and when the length of the mounting column 310 is equal to the length of the quick connector 200, the end of the mounting column 310 can be flush with the inner wall of the tank body 100, both of which can make the mounting column 310 fully fill the entire quick connector 200, thereby avoiding a large amount of liquid medicine from entering the quick connector 200.
