Description

Technical Field

[0001] This utility model relates to the field of medical cleaning technology, specifically a steel needle cleaning, drying and sterilization device. Background Technology

[0002] When extracting test solutions (such as test samples, test reagents, etc.) on diagnostic equipment, medical steel needles are usually used for extraction. After each extraction of test solutions, the medical steel needles need to be cleaned.

[0003] In existing technologies, after extracting the test solution using steel needles, the needles are typically cleaned manually, resulting in poor cleanliness and low efficiency. Some current methods employ mechanized cleaning, where the needle washing structure is integrated with the steel needle mounting structure. During washing, the steel needle moves up and down within the washing head, while water enters through the tube at the head and exits through the tube at the bottom, completing the cleaning process. However, in this type of washing structure, the washing head moves back and forth and side to side with the steel needle, resulting in complex piping arrangements. Over time, the piping in the washing head can wear down, posing a risk of leakage. Furthermore, some methods involve continuing to move the steel needle in a cleaning tank, followed by drying on another device. This results in large and complex steel needle cleaning equipment that lacks sterilization capabilities. Utility Model Content

[0004] The purpose of this invention is to provide a steel needle cleaning, drying and sterilization device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel needle cleaning, drying and sterilization device, including a cleaning tank, a cleaning component in the cleaning tank, a water pump and a suction component connected to the cleaning component, a water supply tank connected to the water pump, a lifting mechanism above the cleaning component, and a robotic arm connected to the lifting mechanism;

[0006] The cleaning assembly includes a mounting base. Above the mounting base, a sterilization block, a cleaning block, and a drying block are sequentially connected from top to bottom. The cleaning block has a first connector, and the drying block has a second connector. The sterilization block is an annular structure with a sterilization hole that runs vertically through it. The cleaning block has a cleaning hole that runs vertically through it and is connected to the sterilization hole. The inner side of the cleaning hole has a frustoconical guide ring with a larger diameter at the upper end than at the lower end. The cleaning hole and the lower middle part of the guide ring form a water guide groove. The side of the cleaning block has a water inlet hole that connects the first connector and the water guide groove. The drying block has a drying hole that runs vertically through it and is connected to the cleaning hole. The side of the drying hole is connected to a suction hole that connects to the second connector.

[0007] Further optimization involves attaching a flexible PCB board to the surface of the sterilization block, and providing several UV lamp beads on the inner wall of the sterilization holes.

[0008] Preferably, the number of UV lamp beads is five, and the power of the UV lamp beads is 1W.

[0009] Further optimization involves the sterilization block being a ring-shaped heating block or having a ring-shaped heating wire inside it;

[0010] Preferably, the sterilization block or annular heating wire is made of nickel-chromium alloy, and the heating temperature range of the annular heating wire is 200-300℃.

[0011] Further optimization includes a waterproof fan for suction, an air inlet pipe connected between the waterproof fan and the second connector, an air outlet pipe at the air outlet of the waterproof fan, and the end of the air outlet pipe away from the waterproof fan connected to the cleaning tank.

[0012] Further optimization involves a high-speed hollow motor for the waterproof fan, and a one-way valve connected to the air inlet pipe for discharging the cleaning fluid accumulated inside the air inlet pipe. The one-way valve is located above the cleaning tank and at the lowest point on the air inlet pipe.

[0013] Further optimization involves connecting water pipes between the water pump, the first connector, and the water supply tank. The water supply tank is located on the side of the cleaning tank and has an overflow hole between it and the cleaning tank to prevent the cleaning liquid in the cleaning tank from overflowing into the equipment. The bottom of the cleaning tank has a drain hole for discharging the cleaning liquid in the cleaning tank.

[0014] Further optimization involves a lifting mechanism that includes a connecting base connected to the robotic arm. An inverted stepper motor is mounted on the connecting base, and a vertically positioned ball screw is connected to the lower output shaft of the stepper motor. The ball screw's ball nut is connected to a steel needle mounting bracket for installing steel needles. The stepper motor drives the ball screw to rotate, achieving linear motion of the ball screw's ball nut, thereby moving the steel needle mounting bracket up and down.

[0015] Further optimization involves a linear guide rail connecting the steel needle fixing seat and the connecting seat to ensure smooth and stable movement of the steel needle fixing seat; the lower end of the connecting seat is provided with a limiting plate to limit the downward movement of the lifting mechanism and to protect the steel needle.

[0016] Beneficial effects: The steel needle cleaning, drying and sterilization device of this utility model, through the coordinated arrangement of the cleaning component, water pump and suction component, realizes the sterilization, cleaning and drying of steel needles, ensuring the cleanliness of steel needles. Under the action of the lifting mechanism, the steel needles are thoroughly cleaned from top to bottom, and the steel needles can be continuously cleaned under the action of flowing cleaning liquid. The cleaning effect is good, and the cleaned steel needles are dried without any cleaning liquid residue left on the steel needles. This will not affect subsequent use or cause the cleaning liquid to drip onto the experimental table, thus avoiding contamination of the experimental table or affecting the experimental results.

[0017] The sterilization block sterilizes the steel needles during the cleaning process, avoiding cross-contamination between different samples. The suction assembly removes liquid from the steel needles, drying them completely. The removed liquid is then discharged into the cleaning tank through the exhaust pipe, preventing the cleaning solution from being blown everywhere and contaminating the equipment or adversely affecting its use. The suction assembly is also equipped with a one-way valve to prevent cleaning solution from accumulating in the air inlet pipe.

[0018] The steel needle cleaning, drying and sterilization device has a simple structure, few pipes and simple layout. At the same time, the pipes are fixed and will not move with the needle washing action, which can avoid the risk of pipe wear and water leakage caused by the movement of the pipes with the steel needles during the needle washing process, thus ensuring high safety. It can realize the automated cleaning of steel needles and has high cleaning efficiency. Attached Figure Description

Detailed Implementation

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0028] like Figure 1-4 As shown, a steel needle cleaning, drying and sterilization device includes a cleaning tank 1, a cleaning component 2 is provided in the cleaning tank 1, the cleaning component 2 is connected to a water pump 3 and a suction component 4, the water pump 3 is connected to a water supply tank 5, a lifting mechanism 6 is provided above the cleaning component 2, and a mechanical arm 7 is connected to the lifting mechanism 6.

[0029] The cleaning assembly 2 includes a mounting base 21. Above the mounting base 21, a sterilization block 22, a cleaning block 23, and a drying block 24 are connected sequentially from top to bottom. The cleaning block 23 has a first connector 25, and the drying block 24 has a second connector 26. The sterilization block 22 is an annular structure with a sterilization hole 221 that runs vertically through it. The cleaning block 23 has a cleaning hole 231 that runs vertically through it and is connected to the sterilization hole 221. The inner side of the cleaning hole 231 has a frustoconical guide inner ring 232. The upper diameter of the guide inner ring 232 is larger than the lower diameter. The cleaning hole 231 and the lower middle part of the guide inner ring 232 form a water guide groove 234. The side of the cleaning block 23 has a water inlet hole 233 that connects the first connector 25 and the water guide groove 234. The drying block 24 has a drying hole 241 that runs vertically through it and is connected to the cleaning hole 231. The side of the drying hole 241 is connected to a suction hole 242 that is connected to the second connector 26.

[0030] In this application, the steel needle cleaning, drying, and sterilization device is used for cleaning steel needles, capable of cleaning, sterilizing, and drying them. The cleaning tank 1 holds the cleaning solution for the steel needles, allowing for collection, recycling, and subsequent processing. The cleaning assembly 2 is used for cleaning the steel needles, sterilizing, cleaning, and drying them. It works with a water pump 3 to supply the cleaning solution and wash the steel needles, and with a suction assembly 4 to suction air from the steel needles for drying. A water supply tank 5 provides the cleaning solution and is connected to the water pump 3. The water pump 3 pumps the cleaning solution from the water supply tank 5 and sprays it onto the steel needles inserted into the cleaning assembly 2, thus cleaning the steel needles. A lifting mechanism 6 moves the steel needles up and down, achieving overall cleaning. A robotic arm 7 moves the lifting mechanism 6, facilitating the installation and removal of the steel needles.

[0031] In this application, the cleaning component 2 includes a mounting base 21, a sterilization block 22, a cleaning block 23, and a drying block 24. The mounting base 21 is used to install the cleaning module composed of the sterilization block 22, the cleaning block 23, and the drying block 24. The sterilization block 22 is used to sterilize the steel needles. The cleaning block 23 is used to wash the steel needles with water to remove stains. The drying block 24 is used to dry the steel needles, facilitating the removal of cleaning liquid from the steel needles, which is achieved through the suction of the suction component 4. The first connector 25 is used to connect the cleaning block 23 to the water pipe, and through the water pipe to the water pump 3, so that the water pumped by the water pump 3 can flow into the water guide groove 234 of the cleaning block 23 through the water pipe and the first connector 25, and form a circular water outlet through the water guide groove 234, which can wash the entire circumference of the steel needle passing through the cleaning hole 231, ensuring that the steel needle can be thoroughly cleaned and its cleanliness is guaranteed. The sterilization block 22 has a ring-shaped structure, formed by sterilization holes 221. Steel needles are inserted into the sterilization holes 221, and the sterilization block 22 sterilizes the passing steel needles. The cleaning hole 231 allows the steel needles to pass through, and the cleaning solution introduced through the first connector 25 flows into the cleaning hole 231 to clean the steel needles. The guide inner ring 232 has a frustoconical structure, forming a structure that is larger at the top and smaller at the bottom. This guides the water entering the cleaning hole 231 to form a conical flow, meaning the water in the inlet hole 233 flows into the water guide groove 234 formed by the cleaning hole 231 and the guide inner ring 232. This causes the water in the water guide groove 234 to flow in a ring shape and downwards along the guide inner ring 232 towards the center, ultimately forming a surrounding flush of the steel needles passing through the guide inner ring 232. This allows for flushing of the entire circumference of the steel needles without rotating them. The steel needle enters the drying hole 241 of the drying block 24, and is dried by the suction assembly 4, removing the cleaning liquid from it. The suction assembly 4 draws air into the drying hole 241 through the second connector 26 and the suction hole 242, removing the cleaning liquid from the steel needle and achieving drying. The sterilization hole 221, cleaning hole 231, and drying hole 241 form a through-hole structure that is vertically connected. Under the action of the lifting mechanism 6, the steel needle can move up and down within the through-hole formed by the sterilization hole 221, cleaning hole 231, and drying hole 241, facilitating cleaning, sterilization, and drying of the steel needle from both the top and bottom.

[0032] like Figure 3 and Figure 4 As shown, in one embodiment of this application, the surface of the sterilization block 22 is covered with a flexible PCB board, and the inner wall of the sterilization hole 221 is provided with a plurality of UV lamp beads 222.

[0033] In this embodiment, UV lamp beads 222 are arranged on the inner wall of the sterilization hole 221, and the light emitted by the UV lamp beads 222 is used to irradiate and sterilize the steel needle. The UV lamp beads 222 can emit ultraviolet light, which destroys the DNA structure of microorganisms on the surface of the steel needle to achieve a sterilization effect. A flexible PCB board is disposed on the surface of the sterilization block 22 for controlling the UV lamp beads 222.

[0034] Preferably, the number of UV lamp beads 222 is five, and the power of each UV lamp bead 222 is 1W. The five UV lamp beads 222 are arranged in a ring to achieve full irradiation of the entire circumference of the steel needle, ensuring the sterilization effect of the UV lamp beads 222. The power of the UV lamp beads 222 is 1W, which generates little heat and will not affect the flexible PCB board attached to the surface of the sterilization block 22.

[0035] like Figure 3 and Figure 4 As shown, in another embodiment of this application, the sterilization block 22 is an annular heating block or has an annular heating wire inside.

[0036] In this embodiment, the sterilization block 22 is an annular heating block with a heating function, which can directly sterilize the passing steel needle by burning. The sterilization block 22 can also be made by setting an annular heating wire inside, which also has the effect of sterilizing the steel needle by burning.

[0037] Preferably, the sterilization block is made entirely of nickel-chromium alloy or the annular heating wire is made of nickel-chromium alloy, with the heating temperature range of the annular heating wire being 200-300℃. Sterilization blocks or annular heating wires made of nickel-chromium alloy have the advantage of stable operation in high-temperature environments and are not easily deformed or structurally altered after long-term use. They also have high resistivity, generating more heat under the same current, making them very suitable as heating modules for heating and sterilizing steel needles. The heating temperature of the annular heating wire, at 200-300℃, can effectively sterilize steel needles through heat treatment.

[0038] like Figure 1 , Figure 5 and Figure 6 As shown, in another embodiment of this application, the suction assembly 4 includes a waterproof fan 41 for suction, an air inlet pipe 42 is connected between the waterproof fan 41 and the second connector 26, and the air outlet of the waterproof fan 41 is provided with an air outlet pipe 43, the end of the air outlet pipe 43 away from the waterproof fan 41 is connected to the cleaning tank 1.

[0039] In this embodiment, the suction assembly 4 includes a waterproof fan 41, an air inlet pipe 42, and an air outlet pipe 43. When the waterproof fan 41 is working, it generates a low-pressure zone inside, much lower than atmospheric pressure, which can draw in the water-laden air from the drying holes 241 of the drying block 24 through the suction holes 242, the second connector 26, and the air inlet pipe 42, and then discharge it through the air outlet pipe 43. The water-laden air enters the cleaning tank through the air outlet pipe 43, facilitating the collection of moisture in the sucked-out air and preventing cleaning liquid from spraying onto other places and affecting the environment.

[0040] like Figure 5 and Figure 6 As shown, further, based on the above scheme, in another embodiment of this application, the waterproof fan 41 is a high-speed hollow motor, and a one-way valve 44 is connected to the air inlet pipe 42. The one-way valve 44 is located above the cleaning tank 1 and at the lowest point on the air inlet pipe 42.

[0041] In this embodiment, the waterproof fan 41 is a high-speed hollow motor with its blades inside and the motor coil externally mounted. When the motor coil is energized, it generates a magnetic field, which drives the internal blades to rotate via electromagnetic induction. This rotation of the blades blows air towards the outlet duct 43, creating a low-pressure zone inside the motor due to insufficient airflow. This draws air away from the inlet duct 42, achieving the purpose of air intake. Ultimately, it removes the water-laden air from the drying hole 241, drying the steel needles located within it. Because the motor coil is located externally, there is ample space for heat dissipation, unlike small high-speed fans that require airflow through the coil for cooling. Furthermore, because the gaps at the motor's edge are under high pressure (equal to atmospheric pressure), moisture cannot enter the bearings and other components through these gaps, thus effectively protecting the motor and preventing moisture corrosion of the fan, bearings, etc.

[0042] In this embodiment, neodymium iron boron magnets can be used as stators, and four pairs of magnetic poles can be used to realize large-diameter high-speed fans.

[0043] In this embodiment, a one-way valve 44 is connected to the air inlet pipe 42, which allows the cleaning fluid accumulated in the air inlet pipe 42 to be discharged. The one-way valve 44 is located above the cleaning tank 1, facilitating the return of the discharged liquid to the cleaning tank 1. Simultaneously, the one-way valve 44 is located at the lowest point on the air inlet pipe 42, ensuring that the cleaning fluid accumulated in the air inlet pipe 42 converges towards the one-way valve 44, achieving drainage. Furthermore, in this embodiment, when the waterproof fan 41 is operating, the valve plate of the one-way valve 44 is sucked up to close the pipe opening, preventing insufficient air pressure at the drying block 24 due to air intake through the one-way valve 44. When the waterproof fan 41 stops operating, the valve plate of the one-way valve 44 falls down, allowing the cleaning fluid in the air inlet pipe 42 to flow towards the one-way valve 44, exiting through the valve plate gap and entering the cleaning tank 1.

[0044] like Figure 1 As shown, in another embodiment of this application, water pipes are connected between the water pump 3, the first connector 25, and the water supply tank 5. The water supply tank 5 is located on the side of the cleaning tank 1 and has an overflow hole between it and the cleaning tank 1. A drain hole is provided at the bottom of the cleaning tank 1.

[0045] In this embodiment, the water pump 3 is connected to the first connector 25 of the cleaning component 2 via a water pipe, enabling the cleaning fluid to be pumped into the cleaning block 23 for cleaning the steel needles. The water pump 3 is also connected to the water supply tank 5 via a water pipe, providing the cleaning fluid. An overflow hole is provided between the water supply tank 5 and the cleaning tank 1, allowing the cleaning fluid in the cleaning tank 1 to flow into the water supply tank 5 after reaching a certain height, preventing the cleaning fluid from overflowing into the equipment. It also prevents the cleaning agent from overflowing into the equipment due to pipe blockage or other reasons, ensuring timely drainage from the bottom drain hole of the cleaning tank 1. The drain hole is located at the bottom of the cleaning tank 1 for draining the cleaning fluid. In this embodiment, the water supply tank 5 is also connected to an external pump, which automatically replenishes the cleaning fluid if it is insufficient.

[0046] like Figure 7 As shown, in another embodiment of this application, the lifting mechanism 6 includes a connecting seat 61 connected to the robotic arm 7. The connecting seat 61 is provided with an inverted stepper motor 62. The lower output shaft of the stepper motor 62 is connected to a vertically arranged ball screw 63. The ball nut of the ball screw 63 is connected to a steel needle fixing seat 64 for installing steel needles.

[0047] In this embodiment, the lifting mechanism 6 includes a connecting seat 61, a stepper motor 62, a ball screw 63, and a steel needle fixing seat 64. The connecting seat 61 is used for mounting other components of the lifting mechanism 6 and for connecting with the robotic arm 7, enabling the robotic arm 7 to drive the lifting mechanism 6 to move laterally, facilitating the installation and removal of the steel needle. The stepper motor 62 drives the ball screw 63 to rotate, which in turn drives the ball nut of the ball screw 63 to move linearly, thereby driving the steel needle fixing seat 64 to move up and down. The steel needle fixing seat 64 is used for vertical fixing of the steel needle. The up and down movement of the steel needle fixing seat 64 drives the steel needle to move up and down synchronously, thereby enabling the steel needle to move up and down between the sterilization block 22, the cleaning block 23, and the drying block 24, that is, to move up and down within the sterilization hole 221, the cleaning hole 231, and the drying hole 241, achieving sterilization, cleaning, and drying of the steel needle.

[0048] Furthermore, a linear guide rail 65 connects the steel needle fixing seat 64 and the connecting seat 61, and a limiting plate 66 is provided at the lower end of the connecting seat 61. The linear guide rail 65 ensures smooth and precise up-and-down movement of the steel needle fixing seat 64, and the limiting plate 66 is used to limit the position of the lifting mechanism 6 relative to the cleaning component 2, while also protecting the steel needle.

[0049] In this application, the operation process of the steel needle cleaning, drying, and sterilization device is as follows: First, the steel needle is installed on the steel needle fixing seat 64. Then, the stepper motor 62 drives the ball screw 63 to insert the steel needle into the sterilization hole 221, cleaning hole 231, and drying hole 241 of the cleaning component 2. The water pump 3 is started, and the cleaning liquid enters the cleaning hole 231 and the water guide groove 234 of the cleaning block 23 through the water pipe. The cleaning liquid is guided and sprayed onto the steel needle through the guide inner ring 232 to clean the steel needle. The cleaning liquid in the flow channel carries away the dirt on the steel needle. Then, the sterilization block 22 and the suction... The air assembly 4 sterilizes the steel needles via the sterilization block 22 (ultraviolet sterilization or high-temperature sterilization) and dries them via the drying block 24. Specifically, the waterproof fan 41 is activated, and air is drawn into the drying hole 241 of the drying block 24 through the air inlet pipe 42 and the second connector 26 to remove the cleaning liquid from the cleaned steel needles, thus drying them. During the entire process of cleaning, sterilization, and drying, the steel needles are moved up and down by the lifting mechanism 6 until they are clean. Finally, the steel needles are removed by the lifting mechanism 6 and the robotic arm 7.

[0050] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
