Description

Technical Field

[0001] The utility model relates to endoscope cleaning and disinfecting equipment, in particular to a self-cleaning device of an endoscope cleaning machine. Background Art

[0002] At present, due to people's increasing attention to their personal health and some reasons such as irregular diet, the number of endoscopes used for examination in the hospital's endocrinology department is increasing year by year. The endoscope cleaning machine is a device specially designed for cleaning and disinfecting endoscopes. It has the characteristics of high efficiency and automation, which can help medical institutions to quickly and safely clean and disinfect endoscopes to ensure their high-quality reuse. At the same time, it can also effectively avoid the secondary contamination of equipment caused by the negligence of personal hygiene and disinfection when the staff is cleaning and disinfecting the endoscope.

[0003] Therefore, an endoscope cleaning machine with fast, safe and efficient self-cleaning effect will have a good prospect market. However, judging from the currently available equipment, the endoscope cleaning machine will cause dirt residue in some dead corners inside the basin or on the cover during the cleaning process. Due to the splashing of cleaning water during the cleaning process, the dirt residue is mostly on the cover. Therefore, the inside of the basin and the cover require a device with 360° no dead corners to meet the above needs. There are some devices on the market that can perform internal self-cleaning. Through research and comparison, there are many problems, such as: the need for electric drive, the pressure cannot meet the effective flushing effect, and other problems. Utility Model Content

[0004] In order to solve the above technical problems, the purpose of the utility model is to provide a self-cleaning device for an endoscope cleaning machine, which can not only achieve the self-cleaning effect of the endoscope, but also does not require electricity during the cleaning process, so that it can have a better power saving function, while also being able to meet the effect of reducing pressure leakage.

[0005] The utility model provides the following technical solutions:

Therefore, when the high-pressure water source enters the connecting cavity through the pipe connector, the water flow impacts the spiral blade from above, thereby driving the spiral blade to rotate, and then driving the water spray base to rotate, and the impact of the high-pressure water flow will transmit the downward impact force through the water spray upper shell to the water-stop gasket. The water spray upper shell can press the water-stop gasket and the outer ring flange of the bearing under the impact of the water flow, and the setting of the bearing can ensure the smoothness of the rotation, and the rotation speed can also be adjusted according to the amount of water flow, and the water-stop gasket can effectively reduce the pressure leakage.

[0007] Preferably, a threaded ring is provided on the outside of the pipe connector, and a circle of packaging base 2 is also provided on the outside thereof. A group of nuts for threaded installation on the outside of the pipe connector is also provided above the transparent upper cover. The nuts cooperate with the packaging base 2 to press and lock the pipe connector on the transparent upper cover, thereby ensuring the sealing of the package while ensuring detachable installation.

[0008] Preferably, the communicating cavity of the water spray upper shell and the water spray base is connected by a threaded connection, and the tightening direction is the same as the rotation direction of the water spray base, thereby ensuring the detachable connection between the water spray upper shell and the water spray base, and also ensuring the working stability after connection.

[0009] Preferably, the transparent upper cover is hingedly mounted on the frame through a group of folding plate brackets, and a group of electric push rods are also hingedly mounted on the frame, and the driving ends of the electric push rods are connected to the transparent upper cover through connecting plates. Therefore, by starting the lifting and lowering of the driving ends of the electric push rods, the transparent bracket can be rotated around the hinged ends of the folding plate brackets and the frame to open or close, thereby realizing an electric opening and closing method. At the same time, a group of protective covers for protecting the electric push rods are also provided on the frame to ensure safety in use.

[0010] Preferably, the frame is also provided with a powder bin, a touch screen, a power switch and a manual switch on the upper cover which are located on the opposite side of the electric push rod. This position distribution makes it convenient for personnel to control the addition of powder and operate the display screen and the opening switch. That is, the personnel only need to stand on one side of the powder bin, the touch screen, the power switch and the manual switch on the upper cover to operate them. The transparent upper cover is rotated to open, and the opened rotating mouth is set towards the operator. Therefore, it is convenient for personnel to directly place the endoscope.

[0011] The beneficial effects of the utility model are:

[0012] 1. The self-cleaning device of the utility model does not need to use electrical equipment such as motors, but uses the pressure of water flow to impact the spiral blades (the structure is similar to that of a turbine generator), thereby driving the self-cleaning water spray device to rotate, which has the function of saving electricity;

[0013] 2. In the self-cleaning water spray device, due to the support of the bearing, it can ensure that the device can rotate smoothly, and the rotation speed can also be adjusted according to the size of the water flow to meet the needs;

[0014] 3. Since a water-stop gasket is provided between the water spray upper shell and the packaging base of the pipe connector for isolation, the reliability of compression can be ensured during water pressure impact, thereby effectively reducing pressure leakage.

The water-spraying base 43 includes a connecting cavity for connecting with the water-spraying upper shell 42 and a water-spraying pipe 49 installed on the connecting cavity. A spiral blade 45 coaxially arranged with the connecting cavity is installed in the connecting cavity. Therefore, when the high-pressure water source enters the connecting cavity through the pipe connector 41, the water flow impacts the spiral blade 45 from above, thereby driving the spiral blade 45 to rotate, and then driving the water-spraying base 43 to rotate. The impact of the high-pressure water flow will transmit the downward impact force to the water-stop gasket 46 through the water-spraying upper shell 42. The water-spraying upper shell 42 can press the water-stop gasket 46 and the outer ring flange 48 of the bearing 44 under the impact of the water flow. The setting of the bearing 44 can ensure the smoothness of the rotation, and the rotation speed can also be adjusted according to the size of the water flow. The water-stop gasket 46 can effectively reduce the pressure leakage.

The person can place the endoscope in the cleaning basin 2 without moving, and after closing the transparent upper cover 3, the cleaning operation can be controlled by the power switch 10, and the cleaning liquid is injected into the cleaning basin 2 to enter the endoscope cleaning step. When the high-pressure water source enters through the pipe connector 41, the endoscope is cleaned. After entering the connecting cavity, the water flow impacts the spiral blade 45 from above, thereby driving the spiral blade 45 to rotate, and then driving the water spray base 43 to rotate. The impact of the high-pressure water flow will transmit the downward impact force to the water stop gasket 46 through the water spray upper shell 42. The water spray upper shell 42 can press the water stop gasket 46 and the outer ring flange 48 of the bearing 44 under the impact of the impact force of the water flow.
