[0026] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0027] The following is combined with Figures 1 to 4 The following describes embodiments of the present invention.
[0028] like Figure 1 and Figure 2As shown in the embodiment of the utility model, a pretreatment cleaning machine for medical devices is provided, comprising: a cleaning chamber 1 having at least one cleaning compartment 12; a nozzle 32 disposed on the top of the cleaning compartment 12; a cleaning fluid pipeline including a clean water pipeline, an enzyme solution pipeline, a switching valve, and a main pipeline 31, wherein the clean water pipeline and the enzyme solution pipeline are respectively connected to the switching valve, the switching valve is disposed at one end of the main pipeline 31, and the other end of the main pipeline 31 is connected to the nozzle 32; and a control cabinet 2 having a controller and a control panel 21, wherein the control panel 21 is adapted to receive control commands and send them to the controller, and the controller is communicatively connected to the switching valve to control the switching valve to open, close, or switch the connection between the clean water pipeline and the enzyme solution pipeline and the main pipeline 31.
[0029] In this embodiment, the cleaning chamber 1 is made of corrosion-resistant material to accommodate various cleaning solutions. The chamber contains at least one cleaning compartment 12 for holding medical devices requiring cleaning.
[0030] The nozzle 32 is mounted on top of the cleaning chamber 12 and is responsible for evenly spraying the cleaning solution onto the medical device. The nozzle 32 is typically designed with coverage, spray pressure, and uniformity in mind to ensure that the cleaning solution effectively reaches every corner of the medical device.
[0031] The clean water pipeline is used to transport clean water, while the enzyme solution pipeline is used to transport a cleaning solution containing enzymes, which can effectively decompose biological contaminants on medical devices.
[0032] The switching valve can be a three-way valve, capable of selecting between clean water and enzyme solution, or switching between the two. The switching valve is connected to one end of the main line 31. The main line 31 connects the switching valve and the nozzle 32 to deliver the selected cleaning solution from the switching valve to the nozzle 32.
[0033] First, use ordinary tap water to effectively clean impurities and bloodstains from the medical device. Then, use a small amount of enzyme solution to cover the surface of the medical device to achieve a certain moisturizing effect.
[0034] Control cabinet 2 includes a controller responsible for receiving instructions from control panel 21 and controlling various parts of the equipment according to these instructions, including the operation of switching valves. Control panel 21 is the interface for user interaction with the equipment. Operators can input control commands through control panel 21, such as selecting cleaning modes, starting or stopping the cleaning process, etc. Control panel 21 also displays equipment status information, such as cleaning progress, error warnings, etc.
[0035] The controller and the switching valve interact via a communication connection. This connection can be wired or wireless, depending on the equipment design. Based on operator commands, the controller controls the switching valve to open or close, or to switch between the clean water line and the enzyme solution line, connecting it to the main line 31, thereby achieving different cleaning modes.
[0036] The operator first selects the desired cleaning mode via control panel 21. Upon receiving the instruction, the controller controls the switching valve to deliver the corresponding cleaning solution, water, or enzyme solution to the main pipeline 31, which is then sprayed onto the medical device through nozzle 32. After the cleaning process is complete, the controller can automatically switch to the water pipeline for a final rinse, ensuring that no cleaning solution remains on the medical device.
[0037] This pretreatment cleaning machine is designed to improve the efficiency and quality of medical device cleaning while reducing the risk of human error and contamination. Through automation and precise control, it provides a reliable and efficient solution for medical device cleaning.
[0038] Furthermore, the control cabinet 2 is arranged side by side with the cleaning box 1. The control cabinet 2 is equipped with an enzyme solution tank 4 and a water tank. The enzyme solution tank 4 is connected to the enzyme solution pipeline, and the water tank is connected to the clean water pipeline.
[0039] Furthermore, the main pipeline 31 includes a first pipeline and a second pipeline. The first pipeline is connected to the nozzle 32, and the second pipeline is connected to the switching valve. The first pipeline and the second pipeline are detachably connected, for example, by plugging in, so that the cleaning chamber 1 and the control cabinet 2 can be separated, which enhances the flexibility and ease of maintenance of the equipment.
[0040] Furthermore, the cleaning chamber 12 is equipped with a sealed chamber door 13, which has a visualization structure. The visualization structure on the sealed chamber door 13 can be an observation window or an observation hole, allowing the operator to observe the inside of the cleaning chamber 12 without opening the chamber door.
[0041] In addition, the bottom of the cleaning tank 1 is equipped with casters, the top of the cleaning tank 1 is equipped with a push handle 5, and the bottom side wall of the cleaning tank 1 is equipped with a waste liquid connector 14 to discharge waste liquid.
[0042] Furthermore, continue to combine Figure 1 As shown, the control panel 21 is located on the top of the control cabinet 2 and is tilted from top to bottom for easy operation.
[0043] Furthermore, such as Figure 3 and Figure 4As shown, the control panel 21 is equipped with station selection and cancellation buttons, with one selection button and one cancellation button corresponding to each cleaning chamber 12. This design allows operators to quickly and accurately control the cleaning process of each cleaning chamber 12, thereby improving cleaning efficiency and safety. This design also helps reduce operational errors and ensures that the cleaning quality of medical devices meets medical standards.
[0044] The station selection and station cancellation buttons are important components of the pretreatment cleaning machine control panel 21, providing operators with flexible and efficient control methods to adapt to different cleaning needs and conditions.
[0045] Furthermore, the cleaning chamber 12 is configured with two layers, and the control panel 21 is also equipped with a synchronized operation button and a synchronized cancellation button. The synchronized operation button allows the operator to simultaneously activate and control the cleaning process of both cleaning chambers 12, and the synchronized cancellation button is used to cancel the synchronized operation of the two cleaning chambers 12.
[0046] Furthermore, two cleaning chambers 12 are arranged on top of each other, and the two cleaning chambers 12 are separated by a perforated partition 11.
[0047] The dual-layer cleaning chamber 12 design allows for the cleaning of more medical devices simultaneously. During the cleaning process in both chambers, the synchronized operation and synchronized cancellation buttons on the control panel 21 can be used to control the cleaning operation of both chambers uniformly, while the station selection and station cancellation buttons allow for individual control of each chamber. This design provides operational flexibility, allowing for simultaneous or individual operation as needed.
[0048] Furthermore, the control panel 21 is also equipped with buttons for the number of cleaning chambers 12 and the corresponding working mode and working status.
[0049] The control panel 21 also has start and stop buttons.
[0050] The control system allows for mode and workstation selection, supports intelligent operation, and enables one-button start and stop. The entire cleaning process can be completed in just 1 minute, with 40 seconds of tap water cleaning and 20 seconds of enzyme solution cleaning and covering.
[0051] Furthermore, the control panel 21 provides three workstation options: Workstation A, Workstation B, and Workstation C.
[0052] AB. Workstation A represents the upper-level operation mode, workstation B represents the lower-level operation mode, and workstations AB represent simultaneous operation of both upper and lower levels. When a workstation is selected, the corresponding workstation will turn blue, and only one workstation can be selected at a time. There are also three buttons for deselecting workstations: Cancel Workstation A, Cancel Workstation B, and Cancel Workstations AB. Clicking "Cancel Workstation" will return the corresponding workstation to its initial state.
[0053] The flushing control includes two buttons: Run Indicator and Run Complete, used to control and indicate the status of the flushing process.
[0054] At the bottom of the control panel 21 are four buttons: Rinse Start, Rinse Stop, Manual Operation, and a cycle arrow button that can be used to restart or go back to the previous step.
[0055] The control panel 21 also features channel selection: the interface has three channel options, namely "Channel One," "Channel Two," and "Dual Channel." This indicates that the device can process multiple samples simultaneously, or two samples simultaneously in dual-channel mode. Each channel has station selection options, such as "Upper Station," "Lower Station," and "Dual Station." This means the device can perform different cleaning tasks at different stations. Each station has two status indicators: "In Progress" and "Completed." This indicates that the device can display the cleaning progress of each station in real time.
[0056] The bottom of the control panel 21 has "ON" (on), "OFF" (off) and "SET" (set) buttons, which are used to control the device's start-up, stop, and parameter settings.
[0057] By selecting different channels and workstations, multiple samples can be cleaned simultaneously, and waste liquid is collected in waste tanks. The equipment can be controlled via buttons on the interface, and its operating status and sample information can be displayed in real time.
[0058] Obviously, the above embodiments are merely examples for clear illustration and are not intended to limit the implementation.
[0059] For those skilled in the art, various variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom remain within the protection scope of this invention.
