Its main purpose is to ensure the effectiveness and safety of medicines and protect the safety of patients using medicines. The medicine detection titration device is an analysis equipment for medicine testing, mainly used for titration analysis, that is, adding a standard solution with known accurate concentration to the solution of the measured substance until the amount of the added solution substance reacts completely according to the stoichiometric relationship, and then calculating the content of the measured substance according to the concentration and volume of the added standard solution.
[0003] As disclosed in a medicine detection titration device of Chinese patent CN222152106U, the staff can put the burette into the inside of the fixed ring, and rotate the second bolt, so that the second bolt rotates in the inside of the second threaded hole and drives the clamping block to clamp the burette, then the beaker containing different to-be-measured solutions can be put into the inside of the accommodating groove, then the staff can adjust the height of the supporting strip until the burette is adjusted to the appropriate height, then the first bolt is rotated into the first threaded hole to extrude and limit the fixed rod, then the staff can perform titration detection from the beaker at the middle position, then the staff can rotate the knob, the rotation of the knob will drive the rotating rod to rotate in the inside of the bearing, at this time the rotating rod will drive the gear to rotate, the gear will drive the rack to move, so that the rack drives the loading strip to move through the connecting rod, that is, the titration reagent in the inside of the burette is dropped into the beaker containing different to-be-measured solutions, on the one hand, after the reaction is completed, the beaker can be directly taken out from the inside of the accommodating groove, on the other hand, the titration reagent of the burette can react with different to-be-measured solutions, so that one burette can be used to react with different to-be-measured liquids, and the beaker is more easily taken out, which is more efficient and convenient.
[0004] For this structure, although titration work can be performed, the structure is inconvenient for precise titration, resulting in errors in detection data, therefore we propose a medicine detection titration device which can precisely titrate to improve the accuracy of detection data.

[0009] Preferably, the sealing ring has a rubber material, and the sealing ring is sealingly and slidingly arranged on the inner wall of the burette, so that the sliding push disc and the sealing ring can push the liquid in the burette.
[0010] Preferably, the screw rod is threaded on the inner wall of the burette, and the end of the screw rod is rotatably connected to the push disc, so that the screw rod moving towards the inner wall of the burette can smoothly push the push disc, and the sealing ring is prevented from rotating in the burette.

[0013] Compared with the prior art, the utility model has the advantages that:
[0014] 1. This drug testing titration device comprises a titration assembly. When titrating a drug, the burette is clamped inside the fixing ring by a fixing bolt, the beaker is placed directly below the burette, and the handle is turned. This causes the screw to rotate and move into the burette, pushing the pusher plate connected to the end of the screw. Due to the sealing ring fixedly installed on the outer wall of the pusher plate and the inner wall of the burette, the titrant inside the burette is pushed under its constraint. The titration amount is controlled according to the observation window and the scale. When it is necessary to add titrant to the burette, the end of the burette is placed in the liquid, and the handle is turned. This causes the screw to move the pusher plate outward from the burette. The sealing ring fixedly installed on the outer wall of the pusher plate draws the titrant into the burette. This structure allows for precise control of the titration amount through the scale and the observation window, making the test data more accurate. (The support bar, fixing ring, and fixing bolt are existing publicly disclosed technologies in the prior art, therefore their structures are not fully described in this case.)
[0015] 2. The drug testing titration device consists of a protective component. When drug testing titration is required, the protective tube is pulled upwards, causing the third magnetic ring to magnetically attract the first magnetic ring. At this time, titration is performed through the burette. After titration is completed, the protective tube is pulled, causing the second magnetic ring fixedly installed on the inner wall of the protective tube to magnetically attract the first magnetic ring. Under this restriction, the protective tube protects the burette, preventing impurities from adhering to the outer wall of the burette end and preventing foreign objects from colliding and damaging the burette end.

Detailed Implementation
[0023] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.
[0024] Example 1: A preferred embodiment of the drug detection titration device provided by this utility model Figures 1 to 6 As shown: A drug testing titration device, including a support bar 1;
[0025] A fixing ring 2 is fixedly installed at one end of the support bar 1;
[0026] The fixing ring 2 has a fixing bolt 3 connected to its internal thread;
[0027] The processing component 4 is disposed inside the fixed ring 2. The processing component 4 includes a titration component 41 disposed inside the fixed ring 2. The titration component 41 includes a burette 411 sleeved inside the fixed ring 2. An observation window 412 is provided inside the burette 411. A scale line 413 is fixedly installed on the outer wall of the burette 411. A screw 414 is threaded inside the burette 411. A handle 415 is fixedly installed at the end of the screw 414. A push plate 416 is rotatably connected to the end of the screw 414 away from the handle 415. A sealing ring 417 is fixedly installed on the outer wall of the push plate 416.
[0028] In this embodiment, when titration is required for drug testing, the burette 411 is clamped inside the fixing ring 2 by the fixing bolt 3, the beaker is placed directly below the burette 411, and the handle 415 is turned. This causes the screw 414 to rotate and move into the burette 411, pushing the pusher 416 rotatably connected to the end of the screw 414. Due to the sealing ring 417 fixedly installed on the outer wall of the pusher 416 and the sealing sliding with the inner wall of the burette 411, the titrant inside the burette 411 is pushed under its constraint. The titration amount is controlled according to the observation window 412 and the scale line 413. When titrant is added to the burette 411, the end of the burette 411 is placed in the liquid. The handle 415 is turned so that the screw 414 drives the push plate 416 to move outward from the burette 411. The sealing ring 417 fixedly installed on the outer wall of the push plate 416 draws the titrant into the burette 411. This structure can accurately control the titrant quantity through the scale line 413 and the observation window 412, making the test data more accurate. (The support bar 1, the fixing ring 2 and the fixing bolt 3 are existing publicly disclosed technologies in the prior art, so their structures are not fully described in this case.)
[0029] Furthermore, the outer wall of the sealing ring 417 slides in a sealing manner with the inner wall of the burette 411. The sealing ring 417 is made of rubber, and under its constraint, the sliding push plate 416 and the sealing ring 417 can push the liquid inside the burette 411.
[0030] Furthermore, the outer wall of the screw 414 is threaded into the inside of the burette 411, and the end of the screw 414 is rotatably connected to the push plate 416. Under its constraint, the screw 414 moving into the burette 411 can smoothly push the push plate 416, preventing the push plate 416 from causing the sealing ring 417 to rotate inside the burette 411.
[0031] Example 2: Based on Example 1, a preferred embodiment of the drug detection titration device provided by this utility model is as follows: Figures 1 to 6 As shown: The protective component 42 includes a first magnetic ring 421 fixedly installed on the outer wall of the burette 411, a protective tube 422 slidably disposed on the outer wall of the first magnetic ring 421, a second magnetic ring 423 fixedly installed on the inner wall of the protective tube 422, and a third magnetic ring 424 disposed below the second magnetic ring 423.
[0032] In this embodiment, when drug testing titration is required, the protective tube 422 is pulled upwards, causing the third magnetic ring 424 to be magnetically attracted to the first magnetic ring 421. At this time, titration is performed through the burette 411. After titration is completed, the protective tube 422 is pulled, causing the second magnetic ring 423 fixedly installed on the inner wall of the protective tube 422 to be magnetically attracted to the first magnetic ring 421. Under its restriction, the protective tube 422 protects the burette 411, preventing impurities from adhering to the outer wall of the end of the burette 411 and preventing foreign objects from colliding and damaging the end of the burette 411.
[0033] Furthermore, the first magnetic ring 421 is magnetically attracted to the second magnetic ring 423 and the third magnetic ring 424. The inner wall of the second magnetic ring 423 is slidably disposed with the outer wall of the burette 411. Under the restriction of magnetic attraction, the protective tube 422 can stably cover the burette 411.
[0034] In addition, the inner wall of the protective tube 422 is fitted with the outer wall of the burette 411. The inner wall of the protective tube 422 is coated with an adsorbent material. Under its restriction, dust inside the protective tube 422 and on the outer wall of the end of the burette 411 can be adsorbed, preventing dust from adhering to the outer wall of the end of the burette 411.
[0035] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
