Description

Technical Field

[0001] This utility model relates to endoscope cleaning and disinfection equipment, specifically to an endoscope cleaning spray mechanism and cleaning and disinfection equipment. Background Technology

[0002] With the development of technology, people's requirements and standards for medical care are gradually rising. In addition to ensuring that medical devices are disinfected to a qualified standard, disinfection equipment also needs to protect the medical staff who perform disinfection.

[0003] Furthermore, since flexible endoscopes are not resistant to heat and moisture disinfection, chemical methods are generally used for disinfection and sterilization. These chemical methods are divided into immersion and spraying. Immersion requires a large amount of disinfectant and stricter sealing, so most hospitals and manufacturers use the more economical spraying method. How to improve the cleaning and disinfection effect of endoscopes through spraying is a goal that is constantly being verified. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned problems and provide an endoscope cleaning spray mechanism that can spray and wash the endoscope in all aspects, which helps to improve the cleaning and disinfection effect of the endoscope.

[0005] Another objective of this invention is to provide an endoscope cleaning and disinfection device.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] An endoscope cleaning spray mechanism includes a spray assembly and a rotary drive mechanism for driving the spray assembly to rotate.

[0008] The spray assembly is installed in the cleaning and disinfection chamber of the disinfection machine. The spray assembly includes a spray rod and a nozzle. The spray rod is provided with multiple water outlet mounting holes. The nozzle is provided with multiple nozzles and is respectively connected to multiple water outlet mounting holes. Some nozzles are set vertically downward and some nozzles are set downward at an angle.

[0009] The working principle of the above-mentioned endoscope cleaning spray mechanism is as follows:

[0010] During operation, the cleaning solution is delivered to the spray bar via the supply line. The spray bar then distributes the cleaning solution to each nozzle, causing the nozzles to spray downwards from above the endoscope, rinsing it. Because some nozzles are positioned vertically downwards while others are angled downwards, jets are directed at the endoscope in different directions, reducing blind spots and improving the cleanliness of the endoscope, thus enhancing the cleaning and disinfection effect. Furthermore, while spraying, a rotary drive mechanism rotates the spray assembly, causing the nozzles to rotate and spray downwards from above the endoscope, ensuring thorough rinsing.

[0011] In a preferred embodiment of this invention, the centerline of the downwardly tilted nozzle forms a 55-degree angle with the vertical line. Multiple tests have verified that the endoscope achieves the best cleaning effect when the nozzle is tilted downwards at 55 degrees.

[0012] In a preferred embodiment of this utility model, the spray rod is provided with multiple direct spray holes, some of which are located at the top of the spray rod, thereby achieving near 360-degree spraying and achieving the best cleaning effect on the endoscope.

[0013] In a preferred embodiment of this utility model, the spray assembly further includes a spray bar mounting component;

[0014] The spray bar has a mounting hole in the middle, the spray bar mounting component passes through the mounting hole, the spray bar mounting component has a conveying channel inside, and the part of the spray bar mounting component located in the mounting hole has a connecting hole;

[0015] One end of the spray bar mounting component presses a sealing gasket against one opening of the mounting hole, while the other end of the mounting component presses the sealing gasket against the other opening of the mounting hole via a nut. This structure enables a sealed installation of the spray bar. When the cleaning fluid enters the delivery channel of the spray bar mounting component, it flows through the connecting hole into the mounting hole and the inner cavity of the spray bar, and is then sprayed out from multiple nozzles.

[0016] Furthermore, with the mounting holes as the boundary, both ends of the spray bar are equipped with inclined nozzles.

[0017] Furthermore, in the projection parallel to the axis of the spray bar, the tilting directions of the inclined nozzles located at both ends of the spray bar are symmetrical to each other.

[0018] Furthermore, the rotary drive mechanism consists of a downwardly inclined nozzle. When the cleaning fluid is sprayed out, it generates a reaction force, which can drive the entire spray assembly to rotate. There is no need to set an active drive mechanism, which can simplify the structure and save costs.

[0019] Furthermore, the outlet size of a vertically downward-positioned nozzle is smaller than the outlet size of a nozzle positioned at a downward angle.

[0020] In a preferred embodiment of the present invention, the spray assembly further includes a spray connector, which is connected to the spray bar mounting component and the liquid supply pipeline respectively.

[0021] In a preferred embodiment of the present invention, the spray assembly further includes a pressure sensor for detecting the pressure of the cleaning fluid, the pressure sensor being disposed on the spray connector.

[0022] An endoscope cleaning and disinfection device includes the endoscope cleaning spray mechanism.

[0023] Compared with the prior art, the present invention has the following advantages:

[0024] 1. The endoscope cleaning spray mechanism of this utility model is not only equipped with vertically downward spray heads, but also with inclined spray heads, which emit jets in different directions towards the endoscope, which can reduce cleaning dead angles, improve the cleanliness of the endoscope, and thus improve the cleaning and disinfection effect of the endoscope.

[0025] 2. The spray assembly is driven to rotate by a rotary drive mechanism, so that the nozzle sprays downwards from above the endoscope to thoroughly rinse the endoscope. Attached Figure Description

[0028] Figure 4 This is a cross-sectional view of the endoscope cleaning spray mechanism of this utility model. Detailed Implementation

[0029] To enable those skilled in the art to fully understand the technical solution of this utility model, the present utility model will be further described below in conjunction with the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0030] Combination Figures 1-4The endoscope cleaning and disinfection equipment of this embodiment includes an endoscope cleaning spray mechanism, which includes a spray assembly and a rotation drive mechanism for driving the spray assembly to rotate. The spray assembly is disposed in the cleaning and disinfection chamber of the disinfection machine. The spray assembly includes a spray rod 1 and a nozzle 2. The spray rod 1 is provided with multiple water outlet mounting holes. The nozzle 2 is provided with multiple nozzles and is respectively connected to multiple water outlet mounting holes. Some nozzles 2 are set vertically downward and some nozzles 2 are set downward at an angle.

[0031] Combination Figure 3 The centerline of the downward-tilted nozzle 2 forms a 55-degree angle with the vertical line. Multiple tests have verified that the endoscope achieves the best cleaning effect when the nozzle 2 is tilted downwards at 55 degrees.

[0032] Combination Figures 1-4 The spray rod 1 is provided with multiple direct spray holes 3. Some of the direct spray holes 3 are located at the top of the spray rod 1, and some of the direct spray holes 3 are located at the top of the spray rod 1, so as to achieve near 360-degree spraying and achieve the best cleaning effect on the endoscope.

[0033] Combination Figures 1-4 The spray assembly also includes a spray bar mounting component 4; the spray bar 1 has a mounting hole in its middle, and the spray bar mounting component 4 passes through the mounting hole. The spray bar mounting component 4 has a conveying channel inside, and a connecting hole is provided at the portion of the spray bar mounting component 4 located in the mounting hole. One end of the spray bar mounting component 4 presses a sealing washer 5 against one opening of the mounting hole, and the other end of the spray bar mounting component 4 uses a nut 6 to press the sealing washer 5 against the other opening of the mounting hole. Through this structure, the spray bar 1 can be sealed and installed. When the cleaning fluid enters the conveying channel of the spray bar mounting component 4, it flows through the connecting hole into the mounting hole and the inner cavity of the spray bar 1, and then is sprayed out from multiple nozzles 2.

[0034] Furthermore, with the mounting holes as the boundary, both ends of the spray rod 1 are provided with inclined nozzles 2.

[0035] Furthermore, in the projection parallel to the axis of the spray bar 1, the tilting directions of the inclined nozzles 2 at both ends of the spray bar 1 are symmetrical to each other.

[0036] Furthermore, the rotary drive mechanism consists of a downwardly inclined nozzle 2. When the cleaning fluid is sprayed out, it generates a reaction force, which drives the entire spray assembly to rotate. This eliminates the need for an active drive mechanism, simplifying the structure and saving costs. Of course, other active drive mechanisms can also be used, as described in existing technologies.

[0037] Furthermore, the outlet size of the vertically downward-positioned nozzle 2 is smaller than the outlet size of the downward-sloping nozzle 2.

[0038] Combination Figures 1-4 The spray assembly also includes a spray connector 7, which is connected to the spray bar mounting component 4 and the liquid supply pipeline respectively.

[0039] Combination Figures 1-4 The spray assembly also includes a pressure sensor 8 for detecting the pressure of the cleaning fluid, which is disposed on the spray connector 7.

[0040] Combination Figures 1-4 The working principle of the above-mentioned endoscope cleaning spray mechanism is as follows:

[0041] During operation, the cleaning solution is delivered to the spray bar 1 via the supply line. The spray bar 1 then distributes the cleaning solution to each nozzle 2, causing the nozzles 2 to spray downwards from above the endoscope, rinsing it. Since some nozzles 2 are vertically downwards while others are tilted downwards, jets are directed towards the endoscope in different directions, reducing blind spots and improving the cleanliness of the endoscope, thus enhancing the cleaning and disinfection effect. Furthermore, while spraying, a rotary drive mechanism rotates the spray assembly, causing the nozzles 2 to rotate and spray downwards from above the endoscope, ensuring thorough rinsing.

[0042] The above are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above content. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
