Description

Technical Field

[0001] This utility model relates to the field of reagent storage, and in particular to an automatic alarm device for expired reagents. Background Technology

[0002] In medical testing, a large number of reagents need to be stored. When there are many reagents, it takes a lot of time to complete all the tests, which can cause some reagents to expire due to prolonged storage and become unusable. Conventional storage boxes do not have timer or alarm functions, so they cannot promptly remind the testing personnel.

[0003] Chinese patent application date: January 10, 2023, publication number: CN219545498U, discloses a reagent kit storage compartment, including a compartment body. A compartment cover is hinged to the upper part of the compartment body. The cover and the side of the compartment body away from the hinge are connected by a snap fastener. A lifting assembly and a lighting assembly are provided inside the compartment body. The lifting assembly includes a base plate, a pull rope, and a limiting ring. The base plate is slidably connected to the middle of the compartment body. The limiting ring is fixedly connected to the upper middle of the side wall of the compartment body. One end of the pull rope is connected to the upper part of the base plate, and the other end passes through the limiting ring and is fixedly connected to the middle of the compartment cover. In this invention, through the interaction of the pull rope, the limiting ring, and the base plate, opening the compartment cover pulls the pull rope, causing the base plate to move upwards, thus moving the reagent kit upwards. This makes the upper surface of the reagent kit higher than the upper surface of the compartment body, facilitating the retrieval of the reagent kit and making it more convenient to use.

[0004] This technical solution facilitates the storage and retrieval of reagent kits. However, when storing a large number of reagents, it is difficult to detect which reagents have expired due to the different storage times. Using these expired reagents may cause adverse effects, thus requiring further improvement. Summary of the Invention

[0005] In order to solve the problems existing in the background art, this utility model proposes an automatic alarm device for expired reagents.

[0006] An automatic alarm device for expired reagents includes a storage box with a sealed door on the front side. A series of partitions are fixedly arranged on the bottom wall of the storage box, forming a receiving slot between adjacent partitions. A reagent rack is arranged in the receiving slot. A timer is fixedly installed on the front side of the partition, with each timer corresponding to a receiving slot. An alarm component is fixedly installed on the top of the storage box, and a battery is located at the bottom of the storage box. The timer and alarm component are electrically connected to the battery. A limit component is provided on the front side of the partition.

[0007] Based on the above, support plates are fixedly installed on the bottom of both sides of the storage box, and trays are fixedly installed on opposite sides of the two support plates. A U-shaped frame is fixedly installed between the two trays, and the battery is inserted into the U-shaped frame.

[0008] Based on the above, the reagent rack includes a frame plate, which is inserted into a receiving groove. A reinforcing plate is fixedly installed in the middle of the frame plate. Insertion holes are arranged in an array through the top of the frame plate and the reinforcing plate. A bottom support cylinder is fixed in an array on the bottom wall of the frame plate. The bottom wall of the bottom support cylinder is hemispherical.

[0009] Based on the above, a push-button switch is provided on the front side of the partition, and an arrow groove is opened on the front side of the partition, with the arrow groove pointing to the left. The push-button switch and the timer are electrically connected to a controller, and the alarm component includes a buzzer and an indicator light, both of which are electrically connected to the controller.

[0010] Based on the above, the partition plate has a circular groove and a strip groove on its front side. The strip groove is connected to the bottom of the circular groove. The partition plate has a sliding groove at the center of the inner wall of the circular groove and a guide groove at the center of the inner wall of the sliding groove. The diameter of the guide groove is smaller than the diameter of the sliding groove. The limiting component includes a tension spring fixedly installed on the inner wall of the sliding groove. A rotating seat is fixedly installed at the front end of the tension spring. A sliding rod is fixedly installed at the rear side of the rotating seat. The sliding rod is slidably connected in the guide groove. A rotating cylinder is rotatably connected at the front side of the rotating seat. The rotating cylinder is disposed in the sliding groove. A disc is fixedly installed at the front end of the rotating cylinder. A baffle is fixedly installed on the circumferential surface of the disc. The circular groove and the strip groove are used to accommodate the disc and the baffle.

[0011] Based on the above, two mounting grooves are opened through the circumference of the rotating drum. Friction strips are fixedly installed on the inner wall of the rear side of the mounting grooves. A threaded rod is rotatably connected through the center of the insert. The threaded rod is arranged along the axis of the rotating drum. A knob is fixedly installed at the front end of the threaded rod. A threaded collar is threadedly connected to the threaded rod. Two pressure blocks are fixedly installed on the circumference of the threaded collar. The pressure blocks are slidably connected in the mounting grooves. The rear side of the pressure blocks is an inclined surface.

[0012] Based on the above, the length of the baffle is less than the length of the strip groove, and the bottom end of the baffle is an inclined surface.

[0013] This invention has substantial features and advancements compared to existing technologies. Specifically, it uses a timer to keep track of the stored reagents, and triggers an alarm via a buzzer and indicator light when the reagents expire. Multiple reagent racks allow for categorized storage, and multiple reagents can be retrieved at once. After the reagent racks are placed into the receiving slots, a limiting component secures the racks, ensuring they remain stably within the storage box. This invention offers advantages such as expiration alarms and easy reagent retrieval. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-6As shown, an automatic reagent expiration alarm device includes a storage box 100, a sealing door 200 on the front side of the storage box 100, and a series of partitions 300 fixedly arranged on the bottom wall of the storage box 100. A receiving groove is formed between two adjacent partitions 300, and a reagent rack 400 is placed in the receiving groove. A timer 500 is fixedly installed on the front side of the partition 300, and the timer 500 corresponds one-to-one with the receiving groove. An alarm component 600 is fixedly installed on the top of the storage box 100. After the reagent rack 400 is placed in the receiving groove, the timer 500 starts timing. When the reagent expires, the alarm component 600 triggers an alarm. A battery 700 is located at the bottom of the storage box 100, and the timer 500 and alarm component 600 are electrically connected to the battery 700. A limit component 800 is located on the front side of the partition 300.

[0023] In use, support plates 101 are fixedly installed on the bottom of both sides of the storage box 100. A tray 102 is fixedly installed on the opposite side of each support plate 101. A U-shaped frame 103 is fixedly installed between the two trays 102, and the battery 700 is inserted into the U-shaped frame 103. This allows the battery 700 to be detachably installed in the U-shaped frame 103 for easy replacement. The battery 700 is also suspended to facilitate heat dissipation and prevent heat transfer to the reagents, thus ensuring proper reagent storage. In practice, the reagent rack 400 includes a frame plate 401 inserted into a receiving slot. A reinforcing plate 402 is fixedly installed in the middle of the frame plate 401. Insertion holes 403 are arrayed through-holes on the top of the frame plate 401 and the reinforcing plate 402. Bottom support cylinders 404 are arrayed and fixedly installed on the bottom wall of the frame plate 401, with the bottom wall of the bottom support cylinder 404 being hemispherical. The reagent tubes are inserted into the socket 403 and the base tube 404 for storage, and then inserted into the receiving groove through the frame plate 401 for storage. When they are to be used, multiple reagent tubes can be taken out together by removing the frame plate 401 from the receiving groove.

[0024] Specifically, a push-button switch 501 is provided on the front side of the partition 300, and an arrow slot 502 is opened on the front side of the partition 300, pointing to the left to indicate to the user the corresponding receiving slot of the timer 500. After inserting the reagent rack 400 into the receiving slot, pressing the push-button switch 501 starts the timer 500. The push-button switch 501 and the timer 500 are electrically connected to a controller. The alarm component 600 includes a buzzer 601 and an indicator light 602, both of which are electrically connected to the controller. The timer 500 sends timing information to the controller. When the timing exceeds a predetermined time, the controller activates the buzzer 601 and the indicator light 602 to sound an alarm. In addition, the sealing door 200 can be made of transparent acrylic material, allowing the timing information of the timer 500 to be observed from outside the storage box 100. After the buzzer 601 and the indicator light 602 sound the alarm, the expired reagent in a certain reagent rack 400 can be detected by observing the timing information of the timer 500.

[0025] The partition 300 has a circular groove 301 and a strip groove 302 on its front side. The strip groove 302 is connected to the bottom of the circular groove 301. The partition 300 has a sliding groove 303 at the center of the inner wall of the circular groove 301. The partition 300 has a guide groove 304 at the center of the inner wall of the sliding groove 303. The diameter of the guide groove 304 is smaller than the diameter of the sliding groove 303.

[0026] The limiting component 800 includes a tension spring 801 fixedly installed on the inner wall of the slide groove 303. A rotating seat 802 is fixedly installed at the front end of the tension spring 801, and a slide rod 803 is fixedly installed at the rear side of the rotating seat 802. The slide rod 803 is slidably connected in the guide groove 304. Through the tension of the tension spring 801, the rotating seat 802 and the slide rod 803 have a tendency to move backward.

[0027] A rotating cylinder 804 is rotatably connected to the front side of the rotating base 802. The rotating cylinder 804 is disposed within the sliding groove 303. A disc 805 is fixedly installed at the front end of the rotating cylinder 804, and a baffle 806 is fixedly installed on the circumferential surface of the disc 805. A circular groove 301 and a strip groove 302 are used to accommodate the disc 805 and the baffle 806. When the rotating cylinder 804 rotates relative to the rotating base 802, causing the baffle 806 to be vertically downward, the disc 805 and the baffle 806 are embedded into the circular groove 301 and the strip groove 302 under the tension of the tension spring 801. After the reagent rack 400 is inserted into the receiving slot, the insert plate 805 and the baffle 806 are pulled forward, and then rotated to make the rotating cylinder 804 rotate relative to the rotating base 802. This causes the baffle 806 to be in a horizontal state. Finally, the tension of the tension spring 801 causes the baffle 806 to adhere to the front side of the reagent rack 400, blocking the reagent rack 400 and preventing it from detaching from the receiving slot. The length of the baffle 806 is less than the length of the strip groove 302, and the bottom end of the baffle 806 is inclined. Therefore, when removing the insert plate 805 and the baffle 806 from the circular groove 301 and the strip groove 302, the baffle 806 can be pried out of the strip groove 302 by inserting a hand into the gap between the baffle 806 and the bottom wall of the strip groove 302.

[0028] In reality, two mounting slots 807 are cut through the circumference of the rotating drum 804. Friction strips 808 are fixedly installed on the inner wall of the rear side of the mounting slots 807. A threaded rod 809 is rotatably connected through the center of the insert 805. The threaded rod 809 is set along the axis of the rotating drum 804. A knob 810 is fixedly installed at the front end of the threaded rod 809. A threaded collar 811 is threadedly connected to the threaded rod 809. Two pressure blocks 812 are fixedly installed on the circumference of the threaded collar 811. The pressure blocks 812 are slidably connected in the mounting slots 807 to prevent the threaded collar 811 from rotating with the threaded rod 809 when the threaded rod 809 is rotated. The rear side of the pressure block 812 is an inclined surface. When the baffle 806 blocks the front of the reagent rack 400, the screw rod 809 is rotated by turning the knob 810, which in turn drives the screw collar 811 and the pressure block 812 to slide along the mounting groove 807. As the pressure block 812 moves backward, it presses against the free end of the friction strip 808 and pushes the friction strip 808 to deflect outward, so that the friction strip 808 is attached to the inner wall of the slide groove 303, inhibiting the rotating cylinder 804 from sliding in the slide groove 303, and keeping the baffle 806 attached to the front of the reagent rack 400.

[0029] 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.
