Description

Technical Field

[0001] This utility model belongs to the field of drug analysis technology, and specifically relates to a drug analysis device. Background Technology

[0002] Titration is a commonly used method in pharmaceutical analysis. It involves using the color change of an indicator to indicate the titration endpoint, and then calculating the analytical result by visually estimating the volume of standard solution consumed. Titration has wide applications in chemical analysis, and common titration methods include acid-base titration, redox titration, complexometric titration, and precipitation titration.

[0003] Titration devices are required for drug titration testing. For example, Chinese Patent CN221926272U discloses a medical drug analysis device that allows for flexible adjustment of the burette height to improve user convenience during operation and observation. However, the single-sided support of this titration device can only accommodate one burette. When titrating a large number of drugs, it is impossible to complete a large-scale sampling in a short time, which can easily reduce the titration efficiency.

[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a drug analysis device.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a drug analysis device that can solve the problem that the support frame can only install a single burette.

[0007] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0008] A drug analysis device includes: a base and a support mechanism;

[0009] A support column is connected to the base;

[0010] The support mechanism is installed on the support column. The support mechanism includes a connecting rod. One end of the connecting rod is fixedly connected to a first connecting sleeve, which is slidably installed on the support column. The other end of the connecting rod is equipped with an installation plate, on which a plurality of expansion-type fixing mechanisms are installed.

[0011] In one or more embodiments of this utility model, the support column is threadedly connected to the base, which facilitates the replacement of the support column so that the support mechanism can be installed on different support columns to meet the user's needs.

[0012] The first connecting sleeve is threaded with a first fastening bolt. The first fastening bolt is in contact with the support column. Loosening the first fastening bolt allows the first connecting sleeve to slide on the support column, thereby adjusting the vertical height of the support mechanism to meet the user's needs.

[0013] In one or more embodiments of this utility model, a second connecting sleeve is fixedly connected to the end of the connecting rod away from the first connecting sleeve, and a rotating shaft is fixedly connected to the center of the mounting plate. The rotating shaft is rotatably connected to the upper second connecting sleeve, so that the mounting plate can rotate around the second connecting sleeve to adjust the position of the burette on the mounting plate to meet the user's needs.

[0014] In one or more embodiments of this utility model, a second fastening bolt is threadedly connected to the side wall of the second connecting sleeve. The second fastening bolt contacts the rotating shaft, which facilitates the fixing of the mounting plate and makes it difficult for the burette on the mounting plate to rotate, so that the user can perform drug titration testing.

[0015] In one or more embodiments of this utility model, the mounting plate is provided with a plurality of circumferentially evenly distributed through grooves, and the burette can be placed in the through grooves so as to perform drug titration detection.

[0016] The expansion-type fixing mechanism includes an air bladder installed on the inner wall of the through groove. When the air bladder expands, it can compress the outer wall of the burette, thereby fixing the burette onto the mounting plate.

[0017] In one or more embodiments of this utility model, a plurality of circumferentially evenly distributed fixing frames are fixedly connected to the outer wall of the mounting plate, and the plurality of fixing frames correspond to a plurality of through slots respectively, and an air injection pipe is installed on the fixing frame.

[0018] In one or more embodiments of this utility model, a rotating rod is threadedly connected to the gas injection pipe, and a piston is connected to one end of the rotating rod located inside the gas injection pipe. When the rotating rod rotates, the piston can move inside the gas injection pipe.

[0019] In one or more embodiments of this utility model, the piston is slidably disposed inside the air injection pipe and is rotatably connected to the rotating rod, so that the piston can move inside the air injection pipe when the rotating rod rotates.

[0020] In one or more embodiments of this utility model, a connecting pipe is connected to the bottom of the gas injection tube. One end of the connecting pipe is located inside the mounting plate and communicates with the inside of the air bladder. When the piston moves down inside the gas injection tube, the piston can compress the gas inside the gas injection tube and allow the gas inside the gas injection tube to enter the air bladder through the connecting pipe, so that the air bladder expands and the expanded air bladder is used to fix the burette.

[0021] When the piston moves upward in the gas injection tube, it draws gas from the tube and simultaneously draws gas from the bladder through the connecting tube, causing the bladder to contract. At this time, the bladder will not compress the burette, allowing the burette to be removed from the slot.

[0022] In one or more embodiments of this utility model, the top of the air injection tube is provided with an air hole, and the inside of the air injection tube is connected to the outside through the air hole. The air injection tube can maintain air pressure balance with the outside through the air hole, which facilitates the movement of the piston inside the air injection tube.

[0023] Compared with the prior art, the drug analysis device of this utility model can simultaneously install multiple burettes on the support frame, so as to perform titration detection of multiple drugs in a short time, thereby improving the efficiency of drug titration detection and meeting the user's needs.

Detailed Implementation

[0033] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0034] like Figures 1 to 6 As shown, a drug analysis device according to one embodiment of the present invention includes a base 1 and a support mechanism 2.

[0035] The base 1 is connected to a support column 101, which is used to install the support mechanism 2.

[0036] Preferably, the support column 101 is threadedly connected to the base 1, which facilitates the replacement of the support column 101 so that the support mechanism 2 can be installed on different support columns 101 to meet different user needs.

[0037] like Figures 1 to 6 As shown, the support mechanism 2 is installed on the support column 101. The support mechanism 2 can install multiple burettes at the same time, so as to perform titration testing of multiple drugs in a short time, thereby improving the efficiency of drug titration testing and meeting the user's needs.

[0038] The support mechanism 2 includes a connecting rod 201, one end of which is fixedly connected to a first connecting sleeve 202, which is slidably mounted on the support column 101. A first fastening bolt is threaded onto the first connecting sleeve 202, and this bolt contacts the support column 101. Loosening the first fastening bolt allows the first connecting sleeve 202 to slide on the support column 101, thereby adjusting the vertical height of the support mechanism 2 to adjust the vertical height of the burette, thus meeting the user's needs.

[0039] In addition, an installation plate 203 is installed at the other end of the connecting rod 201. The installation plate 203 is used to install multiple burettes at the same time so that multiple drugs can be titrated and tested in a short time, thereby improving the efficiency of drug titration and testing to meet the user's needs.

[0040] Specifically, a second connecting sleeve 204 is fixedly connected to the end of the connecting rod 201 away from the first connecting sleeve 202, and a rotating shaft 205 is fixedly connected to the center of the mounting plate 203. The rotating shaft 205 is rotatably connected to the upper second connecting sleeve 204. Through the cooperation between the second connecting sleeve 204 and the rotating shaft 205, the mounting plate 203 can rotate around the second connecting sleeve 204 to adjust the position of multiple burettes on the mounting plate 203 to meet the user's needs.

[0041] In addition, the second connecting sleeve 204 has a second fastening bolt threaded on its side wall. The second fastening bolt contacts the rotating shaft 205, which facilitates the fixing of the mounting plate 203, making it difficult for the burette on the mounting plate 203 to rotate, so that the user can perform drug titration testing.

[0042] like Figures 1 to 6 As shown, the mounting plate 203 has several circumferentially evenly distributed through slots, and the burette can be installed in the through slots, i.e. Figure 1 The state shown allows for the titration of various drugs, thereby improving the efficiency of drug titration testing and meeting the user's needs.

[0043] like Figures 1 to 6 As shown, the mounting plate 203 is equipped with several expansion-type fixing mechanisms. The expansion-type fixing mechanisms can be used to fix the burette on the mounting plate 203 for drug titration testing.

[0044] The expansion-type fixing mechanism includes an air bladder 206, which is installed on the inner wall of the through groove. When the air bladder 206 expands, it can compress the outer wall of the burette, thereby fixing the burette onto the mounting plate 203.

[0045] In addition, several evenly distributed circumferentially distributed fixing brackets 207 are fixedly connected to the outer wall of the mounting plate 203. The fixing brackets 207 correspond to several through slots, and an air injection pipe 208 is installed on the fixing bracket 207. A rotating rod 209 is threadedly connected to the air injection pipe 208. A piston 210 is connected to one end of the rotating rod 209 inside the air injection pipe 208. When the rotating rod 209 rotates, the piston 210 can move inside the air injection pipe 208.

[0046] When the piston 210 moves down inside the gas injection tube 208, the piston 210 can compress the gas inside the gas injection tube 208, and cause the gas inside the gas injection tube 208 to enter the air bladder 206 through the connecting tube 211, so that the air bladder 206 expands, so as to fix the burette with the expanded air bladder 206.

[0047] When piston 210 moves upward in the gas injection tube 208, piston 210 draws gas from the gas injection tube 208 and at the same time draws gas from the air bladder 206 through the connecting tube 211, causing the air bladder 206 to contract. At this time, the air bladder 206 will not squeeze the burette, allowing the burette to be removed from the through groove.

[0048] Meanwhile, the inflatable air bladder 206 prevents the burette from being rigidly squeezed, ensuring the safety of the burette. It can also be used for burettes of different diameters, thereby improving the overall applicability of the support mechanism 2.

[0049] Specifically, the piston 210 is slidably disposed in the air injection pipe 208 and is rotatably connected to the rotating rod 209, so that when the rotating rod 209 rotates, the piston 210 can move within the air injection pipe 208.

[0050] In addition, a connecting pipe 211 is connected to the bottom of the inflation tube 208. One end of the connecting pipe 211 is located inside the mounting plate 203 and is connected to the inside of the airbag 206. This allows the gas in the inflation tube 208 to enter the airbag 206, causing the airbag 206 to inflate. It can also draw gas out of the airbag 206, causing the airbag 206 to contract.

[0051] Furthermore, the top of the air injection pipe 208 is provided with an air hole 212. The inside of the air injection pipe 208 is connected to the outside through the air hole 212. The air injection pipe 208 can maintain air pressure balance with the outside through the air hole 212, which facilitates the movement of the piston 210 inside the air injection pipe 208.

[0052] In practical use, adjust the height of the mounting plate 203 according to the needs, then place the burette in the through groove, and rotate the rotating rod 209 to move the piston 210 downwards in the gas injection tube 208. When the piston 210 moves downwards in the gas injection tube 208, it compresses the gas in the gas injection tube 208, causing the gas in the gas injection tube 208 to enter the air bladder 206 through the connecting tube 211, thus inflating the air bladder 206. The inflated air bladder 206 then fixes the burette in the through groove. Different burettes can be installed as needed.

[0053] When the burette needs to be removed, the rotating rod 209 is rotated in the opposite direction, causing the piston 210 to move upward in the gas injection tube 208. This draws gas from the air bladder 206 through the connecting tube 211, causing the air bladder 206 to contract. At this time, the air bladder 206 will not squeeze the burette, and the burette can be removed from the through groove.

[0054] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0055] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
