Description

Technical Field

[0001] The present invention relates to the technical field of drug detection, and in particular to a liquid drug detection device and method. Background Art

[0002] Pharmacovigilance involves the safety and quality control of drugs. Different drugs have different qualities, and the adverse reactions they may cause are also different. On the one hand, for drugs with the same active ingredient, different manufacturers have different formulation technologies, different impurity removal rates, and different incidence rates of adverse reactions. On the other hand, drugs may be contaminated due to problems in production, circulation, and storage, which may lead to reduced or deteriorated drug quality, resulting in adverse drug reactions. Therefore, it is necessary to test drugs to detect possible quality problems before use and reduce the occurrence of adverse reactions.

[0003] When testing liquid medicines, commonly used equipment include test tube racks, conductivity meters, dissolved oxygen meters, etc. The test tube racks are used to place test tubes containing liquid medicines. When testing existing liquid medicines, it is necessary to insert the detection head into the liquid medicine. At the same time, the detection process also takes a certain amount of time, and the speed of preparing the medicines to be tested is much faster than the detection time, which causes the medicines to be tested to queue up for testing. The existing test tube rack has a relatively simple structure, and the test tubes containing medicines are mostly placed on the test tube rack with their openings open, so that the detection head can be inserted into the liquid medicine during subsequent testing. The medicines in the test tubes are exposed to the air for a long time, which will cause the volatile components in the medicines to gradually escape into the air, change the composition ratio of the sample, and cause a decrease in the detection accuracy. In addition, when testing a variety of different medicines, the open test tubes increase the possibility of cross-contamination between different medicines. Summary of the invention

[0009] It is further explained that the base is fixedly connected with an extrusion block, and the limiting rods uniformly distributed circumferentially are all extrusion-matched with the extrusion block.

[0010] Further description, the rotating seat is slidably connected to a second limiting column, a spring is arranged between the second limiting column and the rotating seat, the base is provided with grooves evenly distributed circumferentially, and the second limiting column is limitedly matched with adjacent grooves on the base.

[0014] A method for using a liquid drug detection device, based on the above-mentioned liquid drug detection device, comprises the following steps: S1: Place the test tube containing the drug to be tested in the rotating seat, control the test tube to move downward and squeeze the adjacent carrying plate, the carrying plate drives the adjacent rotating plate to rotate, and the rotating plate drives the adjacent cover plate to seal the test tube; S2: When the bearing plate moves downward, the fixing rod is driven to move downward. When the groove on the fixing rod is aligned with the adjacent limiting rod, the limiting rod is inserted into the groove of the adjacent fixing rod under the action of the adjacent spring; S3: When the drug in the test tube in the front queue is tested, the rotating seat is rotated to align the next test tube containing the drug to be tested with the detection head, and the rotating seat drives the second limit column to rotate. When the next test tube containing the drug to be tested is aligned with the detection head, the second limit column 1 is inserted into the adjacent groove on the base under the action of the adjacent spring; S4: When the rotating seat rotates, the limit rod is driven to rotate. When the limit rod contacts the extrusion block, the limit rod is squeezed and moved by the extrusion block.

When the third sliding rod moves downward to the limit position, the third sliding rod pushes the adjacent third fixed block to drive the adjacent sliding block to move downward; S6: After the sliding member drives the detection head to move downward into the medicine, the detection head detects the medicine. After the detection is completed, the sliding member drives the detection head to move upward, and the sliding member drives the symmetrically distributed third sliding rod to move upward. When the third sliding rod moves upward, the adjacent supporting blocks are reset. The symmetrically distributed supporting blocks squeeze the two cleaning cloths to contact the rod-shaped part of the sliding member, thereby cleaning the rod-shaped part of the sliding member and the residual medicine on the detection head. At this point, the detection is completed.

[0015] The beneficial effects of the present invention are as follows: when a test tube containing a drug to be tested is placed in a rotating seat, the present invention causes the carrier plate to drive the adjacent rotating plate to rotate, and the rotating plate drives the adjacent cover plate through evenly distributed springs to seal the test tube opening, thereby preventing volatile components in the drug from escaping into the air, thereby preventing errors in the detection of the drug.

[0016] By inserting the first limiting column into the adjacent groove on the base, the sliding part is maintained in the current position, making it more convenient for the detection head to detect the medicine, and by inserting the second limiting column into the adjacent groove on the base, the test tube can be accurately stopped under the detection head.

[0017] The symmetrically distributed support blocks are used to respectively support the adjacent cleaning cloths to wipe the sliding part and the detection head, thereby wiping off the residual medicines on the surfaces of the sliding part and the detection head, thereby preventing the residual medicines on the surfaces of the sliding part and the detection head from affecting the next detection.

[0018] When wiping the sliding part and the detection head with the cleaning cloth, the cleaning cloth is transferred from the corresponding winding shell on the upper side to the corresponding winding shell on the lower side, so that the cleaning cloth stained with medicines after use is put away, and the sliding part and the detection head are wiped with a cleaning cloth that has not been stained with medicines to ensure cleanliness each time.

DETAILED DESCRIPTION

[0021] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0022] The existing test tube rack has a relatively simple structure. Test tubes containing medicines are mostly placed open on the test tube rack, which will cause the volatile components in the medicines to gradually escape into the air, change the composition ratio of the sample, and cause a decrease in detection accuracy.

[0023] Embodiment 1: A liquid medicine detection device, such as Figure 1 and Figure 2 As shown, it includes a base 1, a sliding member 2 is slidably connected to the right side of the base 1, the sliding member 2 is composed of a block portion and a rod portion, a detection head 3 is arranged on the lower side of the rod portion of the sliding member 2, and a rotating seat 4 is rotatably connected to the left side of the base 1. The rotating seat 4 is provided with six placement slots uniformly distributed in the circumferential direction, and the detection head 3 is located above the adjacent placement slots. Six mounting plates 5 uniformly distributed in the circumferential direction are fixedly connected to the upper side of the rotating seat 4, and a rotating plate 6 is hinged on the upper side of the mounting plate 5. The rotating plate 6 is connected to a cover plate 7 through four uniformly distributed springs. The cover plate 7 is used to block the test tube mouth, so as to prevent the volatile components in the medicine from gradually escaping into the air. The rotating plate 6 and the cover plate 7 are connected by four springs. Even if the rotating plate 6 is not parallel to the test tube mouth, the cover plate 7 can still cover the test tube mouth flatly.

[0024] like Figure 3 As shown, the sliding member 2 is slidably connected to the first limiting column 201, and the first limiting column 201 is composed of a cylinder and a hemisphere. A spring is arranged between the first limiting column 201 and the sliding member 2, and the spring is initially in a compressed state, and is used to provide the first limiting column 201 with an extrusion force on the base 1, so that the sliding member 2 is maintained in the current position, and the base 1 is provided with evenly distributed grooves, and the first limiting column 201 is limitedly matched with the adjacent grooves on the base 1, so that the detection head 3 can be inserted into different depths of the liquid medicine in the test tube for detection and stop at the current position.

[0025] like Figure 2 , Figure 4 and Figure 5 As shown, the mounting plate 5 is hinged with a rotating shell 8, and the rotating shell 8 is slidably connected to a rotating rod 9, which is hinged to the adjacent rotating plate 6. A first fixed shell 10 is fixedly connected to the lower side of the placement groove of the rotating seat 4, and a first sliding rod 11 is slidably connected to the upper side of the first fixed shell 10. A bearing plate 12 is fixedly connected to the upper side of the first sliding rod 11. A spring is arranged between the bearing plate 12 and the rotating seat 4, and the spring is used to reset the adjacent bearing plate 12. Liquid is filled in the rotating shell 8 and the first fixed shell 10. The liquid mentioned here and below is hydraulic oil for transmission, and the rotating shell 8 and the adjacent first fixed shell 10 are connected by a hose.

[0026] like Figure 1 and Figure 5As shown, a fixing rod 13 is fixedly connected to the lower side of the supporting plate 12, and the rotating seat 4 is slidably connected with six F-shaped limiting rods 14 evenly distributed in the circumference. A spring is arranged between the limiting rod 14 and the rotating seat 4. The spring is initially in a compressed state and is used to provide power for the adjacent limiting rods 14 to move. The fixing rod 13 is provided with a groove that cooperates with the adjacent limiting rod 14. The groove on the fixing rod 13 is a triangular prism, and the limiting rod 14 is F-shaped. The limiting rod 14 is provided with an inclined surface obliquely pointing upward. When the limiting rod 14 is inserted into the groove of the adjacent fixing rod 13, the fixing rod 13 cannot move upward, so that the supporting plate 12 transmits the adjacent cover plate 7 to keep the adjacent test tube covered.

[0027] like Figure 1 As shown, an extrusion block 15 is fixedly connected to the right side of the base 1, and a rightward inclined surface is arranged on the front side of the extrusion block 15. The six limiting rods 14 are all pressed and matched with the inclined surface on the extrusion block 15. When the limiting rods 14 are rotated to contact the inclined surface on the extrusion block 15, the limiting rods 14 are squeezed and moved to the right by the extrusion block 15.

[0028] like Figure 2 As shown, the rotating seat 4 is slidably connected to a second limiting column 16, which is composed of a cylinder and a hemisphere. A spring is arranged between the second limiting column 16 and the rotating seat 4, and the spring is used to provide the second limiting column 16 with a force to insert into an adjacent groove on the base 1. The base 1 is provided with six grooves evenly distributed circumferentially. The second limiting column 16 is limitedly matched with the adjacent grooves on the base 1, so that the six placement grooves of the rotating seat 4 are sequentially located below the detection head 3 each time the rotating seat 4 rotates.

[0029] When using the device, first place the device in the working area, then place the test tube containing the drug to be tested in the placement groove of the rotating seat 4, then move the test tube downward and squeeze the adjacent carrying plate 12, the carrying plate 12 compresses the adjacent spring and drives the adjacent first sliding rod 11 to move downward, when the first sliding rod 11 moves downward, the liquid in the adjacent first fixed shell 10 is pressed into the adjacent rotating shell 8 through the hose, the liquid in the rotating shell 8 increases, and the adjacent rotating rod 9 is pushed to move, and when the rotating rod 9 moves, it drives the adjacent rotating plate 6 to rotate, and the rotating plate 6 drives the adjacent cover plate 7 to rotate through the adjacent four springs, and when the carrying plate 12 moves downward, it drives the fixed rod 13 to move downward, when the groove on the fixed rod 13 is aligned with the adjacent limiting rod 14, the limiting rod 14 is inserted into the groove of the adjacent fixed rod 13 under the action of the adjacent spring, and at this time the cover plate 7 rotates to contact with the upper side of the test tube, thereby blocking the opening of the test tube to prevent the volatile components in the drug from gradually escaping into the air and affecting the accuracy of the detection.

[0030] When the drug in the test tube queued in front is tested, the rotating seat 4 is rotated to align the next test tube containing the drug to be tested with the detection head 3. When the rotating seat 4 rotates, the rotating seat 4 drives the second limiting column 16 to rotate. When the second limiting column 16 rotates, it is squeezed and moved by the base 1. The second limiting column 16 moves and compresses the adjacent spring. When the next test tube containing the drug to be tested is aligned with the detection head 3, the second limiting column 16 is aligned with the adjacent groove on the base 1. The second limiting column 16 is inserted into the adjacent groove on the base 1 under the action of the adjacent spring, thereby ensuring that the test tube is in the detection position. Directly below the measuring head 3, the rotating seat 4 rotates and drives the limiting rod 14 to rotate. When the side of the limiting rod 14 away from the center of the rotating seat 4 contacts the inclined surface of the extrusion block 15, the limiting rod 14 is squeezed to the right by the extrusion block 15 and compresses the adjacent spring. When the test tube is located directly below the testing head 3, the limiting rod 14 is separated from the groove of the adjacent fixing rod 13. At this time, the supporting plate 12 moves upward under the action of the adjacent spring. When the supporting plate 12 moves upward, it drives the adjacent rotating plate 6 to rotate through the adjacent first sliding rod 11, so that the cover plate 7 releases the blockage of the test tube and resets it.

[0031] When the test tube is located directly below the detection head 3, the sliding member 2 is controlled to move downward, and the sliding member 2 drives the detection head 3 and the first limiting column 201 to move downward. When the first limiting column 201 moves, it is squeezed by the base 1 and moves backward and compresses the adjacent spring. When the detection head 3 enters the medicine in the test tube, the sliding member 2 stops moving. At this time, the first limiting column 201 is inserted into the adjacent groove on the base 1 under the action of the adjacent spring, so that the sliding member 2 and the detection head 3 stop at the current position to facilitate the detection of the medicine by the detection head 3. After the detection is completed, the sliding member 2 is moved upward to disengage the detection head 3 from the test tube, and then the rotating seat 4 is rotated counterclockwise from the top view to remove the detected test tube from under the detection head 3, and move the next test tube containing the medicine to be detected to under the detection head 3. The above steps are repeated continuously to complete the detection of medicines in multiple test tubes.

[0032] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 6 and Figure 7As shown, it also includes two mounting frames 17 symmetrically distributed front and back, the two mounting frames 17 are fixed to the right side of the base 1, the mounting frames 17 are rotatably connected to two rotating shafts 18 symmetrically distributed up and down, the left sides of the two lower rotating shafts 18 are fixedly connected to the winding shell 19, and the left sides of the two upper rotating shafts 18 are rotatably connected to the winding shell 19, there is a certain resistance between the mounting frames 17 and the adjacent rotating shafts 18, and the resistance between the lower rotating shaft 18 and the adjacent mounting frames 17 is greater than the resistance between the upper rotating shaft 18 and the adjacent mounting frames 17. Force, a second fixed shell 20 is fixedly connected to the left side of the mounting frame 17, and the opposite sides of the two second fixed shells 20 are slidably connected with second sliding rods 21, and the opposite sides of the two second sliding rods 21 are fixed with support blocks 22, and the support blocks 22 are elastic materials with smooth surfaces, which are used to reduce the resistance of the cleaning cloth 23 when it moves, and enable the two support blocks 22 to deform to wrap the sliding part 2 and the detection head 3, and the two winding shells 19 located on the same mounting frame 17 are jointly wrapped with a cleaning cloth 23, and the cleaning cloth 23 bypasses the adjacent support blocks 22.

[0033] like Figure 7 As shown, the two rotating shafts 18 on the lower side are installed with one-way wheels 24, and a sliding frame 25 is fixedly connected to the right side of the sliding member 2. The two one-way wheels 24 are transmitted to the sliding frame 25 through friction. When the sliding frame 25 moves upward, the adjacent rotating shafts 18 are driven to rotate by the one-way wheels 24. When the sliding frame 25 moves downward, the one-way wheels 24 will not drive the adjacent rotating shafts 18 to rotate.

[0034] like Figure 1 and Figure 7 As shown, the right side of the base 1 is slidably connected with two sliding blocks 26 which are symmetrically distributed front and back, there is a certain resistance between the sliding block 26 and the base 1, and the resistance between the sliding block 26 and the base 1 is greater than the resistance between the third fixed block 27 and the adjacent third sliding rod 28, the upper side of the sliding block 26 is fixedly connected with the third fixed block 27, the upper side of the third fixed block 27 is slidably connected with the third sliding rod 28 fixed to the sliding member 2, the second fixed shell 20 and the third fixed block 27 are both filled with liquid, and the two adjacent ones are connected by a hose, and torsion springs are respectively arranged between the two winding shells 19 on the upper side and the adjacent rotating shafts 18, and the torsion springs are always in a stored force state, which is used to make the winding shell 19 drive the adjacent rotating shaft 18 to rotate, and tighten the adjacent cleaning cloth 23 when it is loose.

[0035] When the sliding member 2 moves downward, it drives the sliding frame 25 to move downward, and the sliding frame 25 drives the two one-way wheels 24 to rotate through friction. At this time, the one-way wheels 24 will not drive the adjacent rotating shaft 18 to rotate. The sliding member 2 drives the two third sliding rods 28 to move downward. When the third sliding rod 28 moves downward, the liquid in the adjacent third fixed block 27 is pressed into the adjacent second fixed shell 20 through the hose. The liquid in the second fixed shell 20 increases, pushing the adjacent second sliding rod 21 to move, and the second sliding rod 21 drives the adjacent support block 22 to move in the direction close to the adjacent second fixed shell 20. With the movement of the support block 22, one of the upper sides of the two adjacent winding shells 19 rotates under the action of the adjacent torsion spring to tighten the loose cleaning cloth 23. When the third sliding rod 28 moves downward to the extreme position, the third sliding rod 28 pushes the adjacent third fixed block 27 to drive the adjacent sliding block 26 to move downward.

[0036] When the sliding member 2 drives the detection head 3 to move upward, the sliding member 2 drives the two third sliding rods 28 to move upward. When the third sliding rod 28 moves upward, negative pressure is generated in the adjacent third fixed block 27, and the liquid in the adjacent second fixed shell 20 is pumped into the adjacent third fixed block 27 through the hose, so that the adjacent second sliding rod 21 drives the adjacent support block 22 to reset. At this time, the two support blocks 22 respectively push the adjacent cleaning cloths 23 to pull the upper winding shell 19 to rotate. The rotation of the winding shell 19 causes the adjacent torsion springs to accumulate force. The two support blocks 22 squeeze the two cleaning cloths 23 to contact with the rod-shaped portion of the sliding member 2. At this time, the sliding member 2 continues to drive the detection head 3 to move upward, and the sliding member 2 drives the sliding frame 25 to move upward until it contacts with the one-way wheel 24. The sliding frame 25 passes The two one-way wheels 24 drive the two rotating shafts 18 on the lower side to rotate, and the lower rotating shafts 18 drive the adjacent winding shells 19 to rotate. The two winding shells 19 on the lower side rotate to wind the adjacent cleaning cloths 23 thereon, and the cleaning cloths 23 are transferred from the adjacent winding shells 19 on the upper side to the adjacent winding shells 19 on the lower side, thereby cleaning the residual medicines on the rod-shaped part of the sliding member 2 and the detection head 3. During the transfer of the cleaning cloth 23, the torsion spring adjacent to the upper winding shell 19 accumulates force sufficient to overcome the resistance to the rotation of the adjacent rotating shafts 18, so the upper rotating shaft 18 rotates, and when the sliding member 2 moves to its original position and stops moving, the detection head 3 is separated from the two cleaning cloths 23, and the cleaning cloths 23 stop transferring, and the subsequent detection process only needs to replace the two new cleaning cloths 23.

[0037] Embodiment 3: Based on Embodiment 2, a method for using a liquid drug detection device, based on the above-mentioned liquid drug detection device, comprises the following steps: S1: Place the test tube containing the drug to be tested in the rotating seat 4, control the test tube to move downward and squeeze the adjacent carrying plate 12, the carrying plate 12 drives the adjacent rotating plate 6 to rotate, and the rotating plate 6 drives the adjacent cover plate 7 to seal the test tube; S2: When the carrying plate 12 moves downward, the fixing rod 13 is driven to move downward. When the groove on the fixing rod 13 is aligned with the adjacent limiting rod 14, the limiting rod 14 is inserted into the groove of the adjacent fixing rod 13 under the action of the adjacent spring; S3: When the drug in the test tube in the front queue is tested, the rotating seat 4 is rotated to align the next test tube containing the drug to be tested with the detection head 3, and the rotating seat 4 drives the second limiting column 16 to rotate. When the next test tube containing the drug to be tested is aligned with the detection head 3, the second limiting column 16 is inserted into the adjacent groove on the base 1 under the action of the adjacent spring; S4: When the rotating seat 4 rotates, the limiting rod 14 is driven to rotate. When the limiting rod 14 contacts the extrusion block 15, the limiting rod 14 is squeezed and moved by the extrusion block 15. When the test tube is located directly below the detection head 3, the limiting rod 14 is separated from the groove of the adjacent fixed rod 13. At this time, the bearing plate 12 drives the rotating plate 6 to rotate, so that the cover plate 7 releases the blockage of the test tube; S5: When the sliding member 2 moves downward, it drives the symmetrically distributed third sliding rods 28 to move downward, and the symmetrically distributed third sliding rods 28 drive the symmetrically distributed supporting blocks 22 to move backward, and the two adjacent winding shells 19 tighten the loose cleaning cloth 23. When the third sliding rod 28 moves downward to the limit position, the third sliding rod 28 pushes the adjacent third fixing block 27 to drive the adjacent sliding block 26 to move downward; S6: After the sliding member 2 drives the detection head 3 to move downward into the medicine, the detection head 3 detects the medicine. After the detection is completed, the sliding member 2 drives the detection head 3 to move upward. The sliding member 2 drives the symmetrically distributed third sliding rod 28 to move upward. When the third sliding rod 28 moves upward, the adjacent supporting blocks 22 are reset. The symmetrically distributed supporting blocks 22 squeeze the two cleaning cloths 23 to contact the rod-shaped part of the sliding member 2, thereby cleaning the residual medicine on the rod-shaped part of the sliding member 2 and the detection head 3. At this point, the detection is completed.

10. A method for using a liquid medicine detection device, characterized in that: According to the liquid medicine detection device of claim 9, the specific method of use is as follows: S1: placing a test tube containing the drug to be tested in the rotating seat (4), controlling the test tube to move downward and squeeze the adjacent carrying plate (12), the carrying plate (12) drives the adjacent rotating plate (6) to rotate, and the rotating plate (6) drives the adjacent cover plate (7) to seal the test tube; S2: When the bearing plate (12) moves downward, the fixing rod (13) is driven to move downward, and when the groove on the fixing rod (13) is aligned with the adjacent limiting rod (14), the limiting rod (14) is inserted into the groove of the adjacent fixing rod (13) under the action of the adjacent spring; S3: After the drug in the test tube in the front queue is tested, the rotating seat (4) is rotated to align the next test tube containing the drug to be tested with the detection head (3), and the rotating seat (4) drives the second limit column (16) to rotate. When the next test tube containing the drug to be tested is aligned with the detection head (3), the second limit column 1 (6) is inserted into the adjacent groove on the base (1) under the action of the adjacent spring; S4: When the rotating seat (4) rotates, the limiting rod (14) is driven to rotate. When the limiting rod (14) contacts the extrusion block (15), the limiting rod (14) is squeezed and moved by the extrusion block (15). When the test tube is located directly below the detection head (3), the limiting rod (14) is separated from the groove of the adjacent fixed rod (13). At this time, the bearing plate (12) drives the rotating plate (6) to rotate, so that the cover plate (7) releases the blockage of the test tube; S5: When the sliding member (2) moves downward, it drives the symmetrically distributed third sliding rod (28) to move downward, and the symmetrically distributed third sliding rod (28) drives the symmetrically distributed supporting block (22) to move backward, and the two adjacent winding shells (19) tighten the loose cleaning cloth (23). When the third sliding rod (28) moves downward to the extreme position, the third sliding rod (28) pushes the adjacent third fixed block (27) to drive the adjacent sliding block (26) to move downward; S6: After the sliding member (2) drives the detection head (3) to move downward into the medicine, the detection head (3) detects the medicine. After the detection is completed, the sliding member (2) drives the detection head (3) to move upward. The sliding member (2) drives the symmetrically distributed third sliding rod (28) to move upward. When the third sliding rod (28) moves upward, the adjacent support blocks (22) are driven to reset. The symmetrically distributed support blocks (22) squeeze the two cleaning cloths (23) to contact the rod-shaped portion of the sliding member (2), thereby cleaning the medicine remaining on the rod-shaped portion of the sliding member (2) and the detection head (3). At this point, the detection is completed.
