Description

Technical Field

[0001] This utility model belongs to the field of medical device cleaning equipment, specifically relating to a vacuum ultrasonic pre-cleaning device. Background Technology

[0002] With the continuous development of medical technology, the cleaning of various complex and precision instruments is becoming increasingly common. Therefore, employing appropriate methods to ensure the quality of medical device pretreatment is crucial. Due to the busy schedules in operating rooms and supply rooms, hospitals often lack sufficient time for timely pretreatment of used instruments. Some instruments are even left overnight before cleaning, leading to organic residue that can corrode and cause rust. The drying of organic matter can result in low subsequent cleaning pass rates and high rework rates, making it difficult to guarantee sterilization quality. Furthermore, inadequate pretreatment can cause stiff joints, blunted or broken precision tips, and functional impairment of the instruments, increasing hospital operating costs and, in severe cases, preventing the normal conduct of surgeries. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a convenient vacuum ultrasonic pre-cleaning device to reduce the probability of substandard instrument pretreatment.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a vacuum ultrasonic pre-cleaning device, including a cleaning chamber and a pulsed cleaning assembly installed on a main frame. A heating assembly is installed inside the cleaning chamber. The pulsed cleaning assembly includes a return air pipe, a bubble generator, and a vacuum pumping assembly. One end of the return air pipe is divided into a liquid phase return air pipe and a gas phase return air pipe, which are respectively connected to the cleaning chamber. A liquid phase return air valve and a gas phase return air valve are respectively installed on the liquid phase return air pipe and the gas phase return air pipe. The liquid phase return air pipe is connected to the bubble generator inside the cleaning chamber. The vacuum pumping assembly is connected to the upper part of the cleaning chamber. A touch screen is also installed on the main frame. The touch screen and the pulsed cleaning assembly are both connected to the electrical system.

[0005] Preferably, it also includes an ultrasonic cleaning assembly, which includes multiple transducers and an ultrasonic power supply. The transducers are mounted on the cleaning chamber, and the ultrasonic cleaning assembly is also connected to the electrical system.

[0006] Preferably, the vacuum assembly includes a vacuum pump and a vacuum tube, with one end of the vacuum tube connected to the vacuum pump and the other end connected to the cleaning chamber.

[0007] More preferably, the vacuum pump is connected to a water tank, and both the inlet pipe and outlet pipe of the vacuum pump are connected to the water tank, with a temperature detection device installed inside the water tank.

[0008] Preferably, an air filter is provided at the other end of the return air pipe.

[0009] Preferably, a platinum resistance thermometer is installed at the bottom of the cleaning chamber, and a pressure transmitter is installed at the top of the cleaning chamber.

[0010] Preferably, a liquid level detection device is provided on the cleaning chamber.

[0011] More preferably, the liquid level detection device includes a liquid level switch, a high liquid level protection switch, and a low liquid level protection switch, with the liquid level switch disposed between the high liquid level protection switch and the low liquid level protection switch.

[0012] Preferably, a door is provided above the cleaning chamber, and an electric actuator is provided on the side of the main frame. The lower end of the electric actuator is rotatably mounted on the main frame, and the upper end of the electric actuator is rotatably mounted on the door.

[0013] Preferably, rollers and locking components are provided at the bottom of the main frame.

[0014] More preferably, the locking component is an anchor bolt, which is threaded onto the lower side of the main frame.

[0015] Preferably, the heating component is an electric heating element.

[0016] Compared with existing technologies, the above technical solution has the following beneficial effects: 1. This utility model uses a pulsed cleaning assembly to pre-clean instruments. Gas-phase pulsed cleaning can clean the inside of tubular instruments without docking. Water in the cleaning chamber is evacuated to a boiling state at a set temperature using a vacuum assembly. Air is then introduced into the cleaning chamber through a gas phase return pipe and rapidly repressurized, causing the water inside the tubular instruments to flow repeatedly, thus removing contaminants. Liquid-phase pulsed cleaning, with water evacuated to a boiling state in the cleaning chamber, introduces air through a bubble generator via a liquid phase return pipe and rapidly repressurizes, achieving a vigorous scouring of the load, repeating multiple times to remove contaminants. A touchscreen is installed on the main frame. The touchscreen, ultrasonic cleaning assembly, and pulsed cleaning assembly are all connected to the electrical system. This automated pre-treatment equipment solves the problem of personnel time constraints, allowing for timely pre-treatment of instruments during surgical breaks or after surgery, improving instrument pre-treatment levels and reducing personnel workload.

[0017] 2. The cabin door is closed by an electric push rod, which ensures the tightness of the door and reduces the need for manual operation by medical staff. Attached Figure Description

Detailed Implementation

[0026] Figures 1-7 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-7 The present invention will be further described below.

[0027] like Figures 1-2As shown, this utility model discloses a vacuum ultrasonic pre-cleaning device, including a cleaning chamber 1 mounted on a main frame 28 and a pulsed cleaning assembly. The cleaning chamber 1 is fixedly mounted on the upper part of the main frame 28. A heating assembly is provided inside the cleaning chamber 1. In this embodiment, the heating assembly is an electric heating tube 4. The pulsed cleaning assembly includes a return air pipe 26, a bubble generator 8, and a vacuum pumping assembly. One end of the return air pipe 26 is divided into a liquid phase return air pipe and a gas phase return air pipe, which are respectively connected to the cleaning chamber 1. Liquid phase return air pipes are respectively provided on the liquid phase return air pipe and the gas phase return air pipe. Air valve 7 and gas phase return air valve 9, liquid phase return air pipe are connected to bubble generator 8 in cleaning chamber 1, vacuum assembly is connected to the upper part of cleaning chamber 1, return air pipe, liquid phase return air pipe, vacuum assembly and bubble generator form liquid phase cleaning assembly, return air pipe, gas phase return air pipe and vacuum assembly form gas phase cleaning assembly, touch screen 20 is also installed on main frame 28, touch screen 20 and pulse cleaning assembly are connected to electrical system 21. Automated pretreatment equipment can solve the problem of personnel time occupation and reduce personnel workload.

[0028] like Figures 3-4 As shown, the vacuum assembly includes a vacuum pump 5 and an evacuation pipe 25. The vacuum pump 5 is fixedly installed below the cleaning chamber 1. One end of the evacuation pipe 25 is connected to the vacuum pump 5, and the other end is connected to the cleaning chamber 1 through the evacuation port 10 on the cleaning chamber 1. The evacuation pipe 25 needs to be connected above the water surface in the cleaning chamber 1. In this embodiment, the vacuum pump 5 is a water ring vacuum pump. The vacuum pump 5 is connected to a water tank 11. The water tank 11 can provide and store the working fluid for the vacuum pump 5. The inlet and outlet pipes of the vacuum pump 5 are both connected to the water tank 11. A temperature detection device is installed in the water tank 11. The working fluid of the vacuum pump 5 enters the water tank 11 through the tap water valve 12. If the temperature detection device detects that the temperature in the water tank 11 is low, the working fluid in the water tank 11 can continue to supply the vacuum pump 5. If the temperature detection device detects that the temperature of the working fluid in the water tank 11 is too high to supply the vacuum pump 5, the working fluid in the water tank 11 is replaced.

[0029] An air filter 6 is installed at the other end of the return air pipe 26. The cleaning chamber 1 is connected to a water inlet pipe 24. A cleaning enzyme solution inlet pipe is also connected to the bottom of the cleaning chamber 1. A water inlet valve and a liquid inlet solenoid valve 13 are respectively installed on the water inlet pipe 24 and the cleaning enzyme solution inlet pipe. Before cleaning the instruments, water is added to the cleaning chamber 1 through the water inlet pipe 24. The liquid inlet solenoid valve 13 is opened to add cleaning enzyme solution to the cleaning chamber 1. The electric heating tube 4 heats the water in the cleaning chamber 1 to the set temperature. The vacuum pump 5 draws negative pressure to make the water in the cleaning chamber 1 boil. The externally filtered air is introduced into the cleaning chamber 1 through the liquid phase return air through the air filter 6, the liquid phase return air valve 7, and the bubble generator 8, and is quickly repressurized to achieve a violent flushing of the load. This is a cleaning method that removes contaminants by repeating the process multiple times. It is mainly used to remove contaminants from the outer surface of instruments.

[0030] The electric heating tube 4 heats the water in the cleaning chamber 1 to the set temperature. The vacuum pump 5 draws negative pressure to bring the water in the cleaning chamber 1 to a boiling state. The externally filtered air is introduced into the cleaning chamber 1 through the air filter 6 and the gas phase return valve 9 from the return pipe above the liquid surface, and is quickly repressurized, so that the water inside the tube flows. This process is repeated multiple times to remove contaminants. This cleaning method is mainly used to remove contaminants from the inner surface of instruments. By combining the gas phase pulse cleaning component and the liquid phase pulse cleaning component, the internal and external surfaces of the instruments are pre-cleaned, improving the pre-treatment level of the instruments.

[0031] A platinum resistance thermometer 2 is installed at the bottom of the cleaning chamber 1 to control the temperature inside the cleaning chamber 1, and a pressure transmitter 3 is installed at the top of the cleaning chamber 1 to control the pressure inside the cleaning chamber 1. A liquid level detection device is installed on the cleaning chamber 1, which includes a liquid level switch 16, a high liquid level protection switch 17, and a low liquid level protection switch 27. The liquid level switch 16 is located between the high liquid level protection switch 17 and the low liquid level protection switch 27. When the water volume reaches the level of the liquid level switch 16, the liquid level switch 16 transmits a signal to the electrical system 21, and the electrical system 21 closes the water inlet pipe 24. The high liquid level protection switch 17 and the low liquid level protection switch 27 are used to limit the highest and lowest water levels in the cleaning chamber 1 to ensure the safety of the cleaning chamber 1 during the cleaning process. A drain outlet is installed at the bottom of the cleaning chamber 1, which is connected to a drain pipe and a drain pump 15. A drain valve 14 is installed on the drain pipe. After cleaning, the drain valve 14 is opened, and the water in the cleaning chamber 1 is drained by the drain pump 15.

[0032] In this embodiment, an ultrasonic cleaning assembly is also provided. The ultrasonic cleaning assembly includes multiple transducers 22 and an ultrasonic power supply 23. The transducers 22 are installed on the cleaning chamber 1. The ultrasonic cleaning assembly is also connected to the electrical system 21. Before performing pulse cleaning, ultrasonic cleaning can be turned on first. The dirt that is broken up by ultrasonic cleaning cannot be washed away, but liquid phase pulse and gas phase pulse can effectively supplement it, peeling the dirt that has been broken up by ultrasonic vibration from the surface of the object. In this embodiment, ultrasonic vibration is turned on first to shake off the dirt, and then vacuuming and returning to air are performed. The ultrasonic activation time is shorter, and the damage to the instruments is smaller.

[0033] like Figures 5-7As shown, the main frame 28 is equipped with an outer shell, and the touch screen 20 is mounted on the outer shell. A door 19 is located above the cleaning chamber 1. An electric actuator 18 is located on the side of the main frame 28, with its lower end rotatably mounted on the main frame 28 and its upper end rotatably mounted on the door 19. The electric actuator 18 is also connected to the electrical system 21 and can be controlled to open and close the door 19 via the touch screen 220. Rollers 29 and a locking assembly are located at the bottom of the main frame 28. In this embodiment, the locking assembly is an anchor bolt 30, which is threaded onto the bottom of the main frame 28.

[0034] In use, medical staff select "open door 19" on the touchscreen 20, place the instruments requiring pre-cleaning into the cleaning chamber 1, close the door 19, and then select the water inlet command to add water into the cleaning chamber 1 through the water inlet pipe 24. The amount of water added depends on the type and quantity of instruments, ensuring the water level does not exceed the high-level protection switch 17 and is not lower than the low-level protection switch 27. Next, the heating command is selected on the touchscreen 20, and the electric heating element 4 heats the water to the set temperature. Then, ultrasonic cleaning is activated to break up the contaminants on the instrument surface. The vacuum pump 5 is then activated to create a vacuum, while the gas phase return valve 9 and liquid phase return valve 7 are simultaneously activated to allow for reflux, thus removing the ultrasonically broken-up contaminants from the object surface. This automated pre-treatment equipment solves the problem of personnel time constraints, allowing for timely pre-treatment of instruments during surgical breaks or after surgery, improving instrument pre-treatment levels and reducing personnel workload.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
