Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceuticals, in particular to a pH value detection device for pharmaceuticals. Background Art

[0002] In drug research and development, in order to improve the intrinsic quality of drug products, drug stability tests need to be conducted to examine the effects of environmental factors and prescription factors on the stability of drug preparations, so as to screen out the best prescription and provide safe, stable and effective drug preparations for clinical use. Among them, pH value is one of the factors that affect the stability of drug preparations. In the formulation design of solution preparations, the most stable pH value must be determined first.

[0003] In the existing device, the detection probe is usually fixed at a specified position to detect the liquid medicine inside the medicine tank. The pH detection probe is immersed in the liquid medicine for a long time, which can easily cause the detection probe to be corroded and damaged. In addition, when the liquid level inside the medicine tank drops, the position of the pH detection probe needs to be re-fixed, which is a cumbersome operation. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 4A pharmaceutical pH value detection device comprises a medicine tank 1, a detection box 2 is fixedly connected to the top wall of the medicine tank 1, a push plate 4 is sealingly and slidably connected to the inner wall of the detection box 2, a first mounting plate 5 is fixedly connected to the bottom wall of the push plate 4, a connecting rod 11 is symmetrically fixedly connected to the bottom wall of the first mounting plate 5, a second mounting plate 8 is fixedly connected to the other ends of the two connecting rods 11, a first stop block 9 is symmetrically fixedly connected to the side walls of the first mounting plate 5 and the second mounting plate 8, a sealing block 6 is symmetrically penetrated and fixedly connected to the side wall of the detection box 2, a slide groove 12 is opened on the side wall of each sealing block 6, and a second stop block 7 is slidably connected inside each slide groove 12.

[0021] Each side wall of the second stop block 7 is fixedly connected to a plurality of springs 13, and the other end of each spring 13 is fixedly connected to the side wall of the slide slot 12. When the first stop block 9 slides against the side wall of the second stop block 7, the second stop block 7 can be squeezed to slide into the slide slot 12 to compress the spring 13. The elastic force of the spring 13 makes the second stop block 7 tightly against the side wall of the first mounting plate 5, so that the interior of the detection box 2 is in a closed state, thereby preventing the PH detection probe 10 from being corroded and damaged.

[0022] An electric device 3 is fixedly connected to the top wall of the detection box 2, and the movable end of the electric device 3 is fixedly connected to the side wall of the push plate 4. The electric device 3 is specifically an electric telescopic rod, which can drive the push plate 4 to move up and down, and then drive the PH detection probe 10 to descend to the liquid with different liquid level heights for detection, and retract it after the detection is completed.

[0023] A first balancing pipe 15 is fixedly connected to the side wall of the medicine tank 1, and a second balancing pipe 14 is fixedly connected to the side wall of the detection box 2. The first balancing pipe 15 is fixedly connected to the second balancing pipe 14 via a hose. The interior of the detection box 2 is divided into a rod-containing part and a rod-free part via an electric device 3, wherein the second balancing pipe 14 is specifically connected to the rod-containing part of the detection box 2. The first balancing pipe 15 and the second balancing pipe 14 allow the air pressure inside the medicine tank 1 to be balanced when the push plate 4 rises and falls.

[0024] Each of the first stop block 9 and the second stop block 7 is a wedge-shaped structure, and each of the second stop block 7 slides against the side wall of the first mounting plate 5. When the first stop block 9 and the side wall of the second stop block 7 are against each other, a lateral component of force can be generated, thereby achieving the effect of pressing the second stop block 7 into the inside of the slide groove 12.

[0025] The first mounting plate 5 and the second mounting plate 8 are commonly and fixedly connected with a PH detection probe 10. The PH detection probe 10 is composed of a sensor and a secondary meter. It is a prior art and will not be described in detail here.

[0026] In the utility model, when it is necessary to detect the pH value of the medicine liquid in the medicine tank 1, the electric device 3 is started to drive the push plate 4 to slide downward along the inner wall of the detection box 2, and the first stop block 9 symmetrically fixedly connected to the side wall of the second mounting plate 8 first slides against the second stop block 7. The first stop block 9 and the second stop block 7 are both wedge-shaped structures. The vertical force transmitted by the push plate 4 generates a lateral component of force on the action surface, and squeezes the second stop block 7 to make it slide into the slide groove 12. At this time, the bottom of the detection box 2 is in an open state. With the push of the electric device 3, the pH detection probe 10 can be lowered to the medicine liquid with different liquid level heights for detection.

[0027] After the detection is completed, the electric device 3 drives the push plate 4 to slide upward along the inner wall of the detection box 2, driving the PH detection probe 10 to be retracted into the detection box 2. At this time, under the elastic force of the spring 13, the two second abutment blocks 7 are tightly abutted against the side walls of the first mounting plate 5, thereby closing the bottom of the detection box 2 and preventing the PH detection probe 10 from being corroded and damaged by being immersed in the medicine for a long time.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
