Description

Technical Field

[0001] The embodiments of this utility model belong to the field of chemical storage and retrieval technology, and more specifically, relate to a chemical storage and retrieval device for clinical laboratories. Background Technology

[0002] Clinical laboratories inevitably use many types of chemicals when testing patient specimens, including flammable and explosive hazardous chemicals, corrosive hazardous chemicals, toxic and harmful hazardous chemicals, and general chemicals. Due to their special nature, these chemicals require dedicated personnel, dedicated cabinets, and double locks for management. In principle, flammable hazardous chemicals should be stored in explosion-proof cabinets, corrosive hazardous chemicals in corrosion-resistant cabinets, and toxic, harmful, and solid chemicals containing salts in chemical safes. Considering the hazards of chemicals, comprehensive chemical storage and management measures should be established to reduce potential risks.

[0003] Currently, the storage of chemicals in clinical laboratories mainly involves the following two aspects. First, chemical storage: each bottle of chemical must be labeled with its "arrival date" and "number," and arranged in ascending order of numbering from the inside out within the chemical cabinet. Relevant records must be filled out. Second, chemical retrieval: the chemical safety officer and the chemical administrator open the chemical cabinet, retrieve the required chemicals (prioritizing chemicals nearing their expiration date), and fill out relevant records. These records include, but are not limited to: chemical name, current inventory, quantity received, date of receipt, signature of the person receiving the chemicals, quantity issued, date of issuance, signature of the person receiving the chemicals, and signature of the chemical administrator.

[0004] The above methods have achieved chemical storage and retrieval management to a certain extent, but the following technical problems still exist: (1) Both storage and retrieval require manual numbering and recording, which is time-consuming and labor-intensive; (2) Manual recording is prone to omissions and errors, resulting in inconsistencies between actual inventory and records; when taking out chemicals, the near-expiration chemicals may not be taken out first as required; (3) Regarding (2), this method often requires chemical administrators to conduct regular inventory checks, which increases the workload.

Furthermore, by adding an isolation push-in component at the input port, reverse chemical retrieval is prevented, ensuring priority use of chemicals nearing their expiration date. Additionally, a photoelectric sensor is added at the exit; upon detecting changes in chemical usage, the system automatically updates the chemical management information, thereby reducing management costs and promoting the automation and standardization of chemical management.

[0032] The chemical input component 220 conveys the chemical into the front flow channel 212 through the chemical input port 211 and pushes it into the tail flow channel 213. The auxiliary external extraction component 240 removes the chemical from the tail flow channel 213. The isolation and pushing component 230 seals and isolates the chemical input port to prevent reverse external extraction. The storage and retrieval status is sensed by a photoelectric sensor.

[0033] like Figure 1 As shown in this embodiment of the invention, the chemical input component 220 includes:

[0034] The conveyor belt 221 covers the front flow channel 212, the driven pulley 222 of the conveyor belt 221 is connected to the driven pulley 222, the driving pulley 224 of the driven pulley 222 is connected to the driven pulley 222 via the transmission belt 223, and the transmission drive motor 225 drives the driving pulley 224 to rotate.

[0044] Working principle of this utility model embodiment:

[0045] S100: First, chemicals are placed into the chemical input port 211. The chemical input component 220 conveys the chemicals into the front flow channel 212 via a transmission belt. Under the action of the flexible rack 233 on the back of the synchronous belt and the transmission gear 232, two sets of symmetrical pulleys 231 rotate in opposite directions, thereby pushing the input chemicals in one by one and isolating them from the input port in real time to prevent external personnel from taking the chemicals from the input port and reduce management costs. At the same time, chemical information is registered and entered from the touch input screen. After the first photoelectric sensor 250 detects the input of the chemical bottle, the information is packaged and registered. If only the information is entered from the touch input screen or only the bottle carrier is stored, the alarm will be triggered to remind the staff to complete the registration information.

[0046] S200: The chemicals are further carried from the front flow channel 212 into the rear flow channel 213 and onto the drawer plate 242. When needed, the second safety door 102 on the back is opened, the drawer plate 242 is pulled out, and the chemicals can be taken out. The change in state is then detected by the photoelectric sensor 250, and the retrieval information is automatically registered.

[0047] In this embodiment of the invention, by adding a photoelectric sensor, a touch input screen, and an alarm, the system will automatically sound an alarm if information registration is missed when staff deposit chemicals, reminding staff to complete the registration. Furthermore, by adding an isolation push-in component at the input port, reverse chemical retrieval is prevented, ensuring priority use of chemicals nearing their expiration date. Additionally, a photoelectric sensor is added at the exit; upon detecting changes in chemical usage, the system automatically updates the chemical management information, thereby reducing management costs and promoting the automation and standardization of chemical management.
