AI Technical Summary
Existing drug sensitivity test strip dispensers cannot guarantee the number of strips dispensed per hole per batch, which may result in multiple strips being pushed in at the same time or strips not being dispensed at a certain position, affecting the normal progress of the test.
A drug sensitivity test strip dispenser was designed, including an outer cover, a dispensing base, a drug sensitivity strip tube, a rotating inner cylinder, a swing arm, a pressing device, a pressing arm, and a support member. The rotating inner cylinder drives the swing arm to rotate, pushing the drug sensitivity test strip out and to the bottom of the support member. Then, the pressing device drives the pressing arm to press down, ensuring that only one drug sensitivity test strip is dispensed at a time. The outer cover, the rotating inner cylinder, and the pressing device serve as guides, limiting the movement direction of the pressing device and preventing deviation.
This method enables accurate single-dispensing of drug sensitivity test strips, ensuring that multiple strips fall onto the petri dish simultaneously. It avoids situations where strips fail to fall due to pressure deviation, thus improving the accuracy of the experiment and the convenience of operation.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical testing equipment technology, and in particular to a drug sensitivity paper dispenser. Background Technology
[0002] Drug susceptibility testing, also known as antibiotic resistance testing, is a microbiological test designed to understand the sensitivity or tolerance of pathogenic microorganisms to various antibiotics, guiding the rational selection of antibiotics in clinical practice. The method involves taking a specimen containing the pathogen from the patient's infection site, inoculating it onto an appropriate culture medium, and culturing it under specific conditions. Simultaneously, paper discs containing different concentrations and types of antibiotics (referred to as "drug susceptibility discs") are placed on the surface of an agar medium, and the results are observed after a certain incubation period. To ensure the accuracy and ease of operation of drug susceptibility testing, a drug susceptibility disc dispenser is typically used for large-scale testing. However, existing drug susceptibility disc dispensers, when pushing the discs from the dispenser or the disc strip onto the culture dish, may result in multiple discs being pushed into the same position simultaneously, or some discs remaining in a certain position, affecting the normal progress of the test.

[0023] like Figure 1-3 As shown in the figure, this application proposes a drug sensitivity test strip dispenser, including an outer cover 1, a dispensing base 2, drug sensitivity strips 3, a rotating inner cylinder 4, a swing arm 5, a pressing device 6, a pressing arm 7, and a support member 8. Multiple drug sensitivity strips 3, swing arms 5, pressing arms 7, and support members 8 are included. The swing arms 5, drug sensitivity strips 3, and pressing arms 7 are sequentially arranged adjacently to the outer cover 1 and the dispensing base 2. The dispensing base 2 has multiple through holes 21, and multiple support members 8 are respectively arranged corresponding to the multiple through holes 21. One end of the rotating inner cylinder 4 passes through... The outer cover 1 is mounted on the outer cover. The other end of the rotating inner cylinder 4 is rotatably connected to the distribution base 2. One end of the pressing device 6 passes through the rotating inner cylinder 4, and the other end of the pressing device 6 is connected to the distribution base 2. The outer cover 1 has multiple channels 11 on its periphery. Multiple drug sensitivity strips 3 are respectively passed through the multiple channels 11. Multiple pressing arms 7 are respectively set in relation to the multiple through holes 21. Multiple pressing arms 7 surround the periphery of the pressing device 6.

[0024] This utility model relates to a drug sensitivity test strip dispenser, including an outer cover 1, a dispensing base 2, drug sensitivity strips 3, a rotating inner cylinder 4, swing arms 5, a pressing device 6, a pressing arm 7, and a support member 8. The dispensing base 2 has multiple through holes 21. In use, multiple drug sensitivity strips 3 filled with different drug sensitivity test strips are installed on the drug sensitivity test strip dispenser through the channels 11. The support member 8 and the dispensing base 2 form an opening communicating with the through holes 21. Rotating the rotating inner cylinder 4 drives the multiple swing arms 5 to rotate, and the swing arms 5 push the drug sensitivity test strips at the bottom of each drug sensitivity strip 3 out and push them to the support member 8. The bottom of the tall part 8 falls onto the through hole 21, and then the pressing device 6 drives the pressing arm 7 to press down, pushing out the drug sensitivity paper. This ensures that one drug sensitivity paper is taken at a time. The outer cover 1, the rotating inner cylinder 4, and the pressing device 6 are sequentially connected, which to a certain extent plays a guiding role, ensuring that multiple drug sensitivity papers are pushed onto the culture dish at the same time. The drug sensitivity paper dispenser disclosed in this application can ensure the number of drugs taken from each drug sensitivity strip 3 at a time, while limiting the movement direction of the pressing device 6 to ensure that multiple drug sensitivity papers fall synchronously, avoiding the situation where some drug sensitivity papers do not fall due to pressing deviation.
[0025] The rotating inner cylinder 4 includes a snap-fit sleeve 41, an inner cylinder 42, and a rotating base 43. The inner cylinder 42 is mounted on the outer cover 1. The snap-fit sleeve 41 is rotatably mounted on the outer cover 1 at the end away from the distribution base 2 and is connected to one end of the inner cylinder 42. The rotating base 43 is mounted on the distribution base 2 and connected to the other end of the inner cylinder 42. Multiple swing arms 5 are respectively connected to the rotating base 43. The pressing device 6 is sequentially mounted on the inner cylinder 42 and the snap-fit sleeve 41. The periphery of the inner cylinder 42... The inner cylinder 42 is provided with multiple guide grooves 44 and multiple clearance grooves 45. Multiple pressing arms 7 are respectively inserted into the multiple guide grooves 44, and multiple clearance grooves 45 are respectively provided on one side of the multiple guide grooves 44. When the inner cylinder 42 rotates, each pressing arm 7 is engaged in the multiple clearance grooves 45 to avoid mutual interference between the rotating inner cylinder 42 and the pressing device 6. The guide grooves 44 play a guiding role for the pressing device 6 and the pressing arms 7, and restrict the movement direction of the pressing device 6 and the pressing arms 7.
[0026] Each of the clearance grooves 45 has beveled angles 46 on its upper and lower sides near the end of the pressing arm 7. While increasing the size of the port of the clearance groove 45, the beveled angles 46 play a certain guiding role, guiding the pressing arm 7 to move toward the clearance groove 45.
[0027] The snap-fit sleeve 41 includes a first snap-fit member 411, a second snap-fit member 412, and two snap-fit grooves 413. The two snap-fit grooves 413 are respectively provided on the opposite side of the first snap-fit member 411 and the second snap-fit member 412. The outer cover 1 has a protruding edge 12 on its periphery. The two snap-fit grooves 413 are respectively snapped into the protruding edge 12. On the one hand, they snap and fix the rotating inner cylinder 4 and the outer cover 1. On the other hand, they restrict the rotation of the rotating inner cylinder 4.
[0028] The rotating base 43 includes a base 431, an outer cylinder 432, an inner column 433, and a torsion spring 434. The base 431 is connected to the inner cylinder 42.

The inner column 433 is located on the distribution base 2 and passes through the outer cylinder 432. The torsion spring 434 is located between the outer cylinder 432 and the inner column 433. The two ends of the torsion spring 434 are connected to the base 431 and the distribution base 2, respectively. The torsion spring 434 limits the rotation angle of the rotating inner cylinder 4 during rotation and drives the rotating inner cylinder 4 to return to its original position after rotation.
[0029] The pressing device 6 includes a guide post 61, a limiting member 62, a limiting post 63, and a return spring 64. A snap-fit cylinder 47 is provided on the inner side of the inner cylinder 42. The guide post 61 passes through the snap-fit cylinder 47. The guide post 61, the limiting member 62, and the limiting post 63 are connected in sequence. The limiting member 62 and the snap-fit cylinder 47 are snapped together. The return spring 64 is sleeved on the limiting post 63. The two ends of the return spring 64 abut against the limiting member 62 and the rotating base 43, respectively. The snap-fit cylinder 47 and the limiting member 62 are snapped together to restrict the movement of the pressing device 6. At the same time, the snap-fit cylinder 47 guides the guide post 61. Pressing the guide post 61 compresses the return spring 64. The pressing device 6 drives multiple pressing arms 7 to press down to push out the drug-sensitive paper sheets under each of the supporting members 8.
[0030] The distribution chassis 2 includes an inner support plate 22, a connecting cover 23, a snap-fit cover 24, and multiple guide covers 25. Multiple through holes 21 are respectively provided on the inner support plate 22. The connecting cover 23 is located on one side of the inner support plate 22 and connected to the outer cover 1. The snap-fit cover 24 is located on the side of the inner support plate 22 facing away from the connecting cover 23. Multiple guide covers 25 are all located on the side of the inner support plate 22 facing away from the outer cover 1. Each of the multiple through holes 21 is provided with a corresponding one-to-one connection. The snap-fit cover 24 and the multiple guide covers 25 are frustoconical in shape. When the drug sensitivity paper dispenser is placed on the culture dish, the snap-fit cover 24 is used to align the dispenser with the culture dish. When the drug sensitivity paper falls into the through hole 21, each of the guide covers 25 plays a limiting role in preventing the drug sensitivity paper from falling directly onto the culture dish. When the pressing arm 7 pushes, it guides the drug sensitivity paper to fall.
[0031] Each of the pressing arms 7 includes a guide cylinder 71, an extension rod 72, and a pusher column 73. The guide cylinder 71 is disposed on any of the supporting members 8. The two ends of the extension rod 72 are respectively connected to the pressing device 6 and the pusher column 73. The pusher column 73 passes through the guide cylinder 71. The guide cylinder 71 is provided to restrict the movement direction of the pusher column 73 and to restrict the relative position of each pressing arm 7 with respect to the outer cover 1, so as to prevent the rotating inner cylinder 4 from driving the pressing arm 7 to rotate and to prevent the position of each pressing arm 7 relative to each through hole 21 from shifting.
[0032] The outer cover 1 is also provided with a receiving cavity 9, in which a desiccant can be placed to ensure that the drug sensitivity paper inside is dry.
[0033] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of this utility model.
