Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to an independent pulse irrigation cleaning device for endoscopes. Background Technology

[0002] An endoscope is a flexible endoscope used for the examination or treatment of human cavities, such as a gastroscope, duodenoscope, and colonoscope. While its material is soft and flexible, its luminal structure is complex (e.g., water / air delivery tubes, suction tubes, auxiliary water delivery tubes), and its surface is prone to forming biofilms (stubborn attachments composed of bacteria, mucus, etc.), which are difficult to penetrate with conventional water flow and chemical disinfectants, requiring special cleaning processes.

[0003] In the process of realizing this invention, the inventors discovered at least the following problems in the prior art:

[0004] (1) Multi-cavity synchronous cleaning: Existing endoscope cleaning equipment lacks independence in the irrigation and cleaning of multiple cavities (such as water / air pipelines, suction pipelines, auxiliary water pipelines, etc.). Uneven pressure can easily lead to incomplete flushing of some cavities, leaving residual biofilm or organic pollutants, resulting in low cleaning efficiency and substandard cleaning.

[0005] (2) Insufficient physical flushing force: Conventional continuous water flow cleaning has limited flushing effect on complex pipe structures (such as lifting clamps and bends), and it is difficult to completely remove stubborn contaminants such as blood and mucus attached to the pipe wall.

[0006] (3) Insufficient compatibility: The diameter of the cavities of different types of endoscopes (such as gastroscopes and duodenoscopes) varies greatly. Existing equipment is difficult to independently adjust the pressure of each cavity, which can easily lead to waste of cleaning fluid or incomplete rinsing.

[0007] (4) Insufficient automation: Manual intervention may lead to substandard cleaning or equipment damage due to operational errors.

[0008] Therefore, how to solve the aforementioned technical problems of existing endoscope cleaning equipment is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0019] Each set of air-liquid inlets includes at least three air-liquid inlets, and each air-liquid inlet is connected to one of the irrigation pipes;

[0020] Each set of gas-liquid interfaces includes at least three gas-liquid interfaces, each of which is connected to one of the gas-liquid inlets and is also used to connect to a cavity of the endoscope.

[0021] Preferably, a first pressure sensor is provided on the connecting pipe between the gas outlet of the gas storage tank and the solenoid valve, and a second pressure sensor is provided on the connecting pipe between each three-way valve and the gas inlet liquid interface. Both the first pressure sensor and the second pressure sensor are signal-connected to the control device.

[0022] Preferably, the irrigation assembly is located at the bottom of the cleaning tank, and all the air-liquid inlets of the irrigation assembly extend beyond the bottom of the cleaning tank.

[0023] Preferably, each set of air-liquid inlets further includes a side-leak air inlet, and the side-leak air inlet extends through the bottom of the cleaning tank and out of the cleaning tank.

[0024] Each set of gas-liquid outlet ports also includes a side-leak gas outlet port, which is connected to the side-leak gas inlet port and is used to connect to the side-leak port of the endoscope.

[0025] Preferably, the cleaning equipment further includes an air filter, which is located on the connecting pipe between the solenoid valve and the air distributor.

[0026] Preferably, a first one-way valve is provided on the connecting pipe between the air filter and the air distributor's inlet end.

[0027] Preferably, a second check valve is provided on the connecting pipe between the outlet of each hydraulic pump and the three-way valve.

[0028] Preferably, the cleaning equipment further includes a frame, the top of which has an opening, and the cleaning tank is disposed in the opening;

[0029] The frame is provided with a first mounting plate on one side along its length direction. The first mounting plate is located adjacent to the bottom of the cleaning tank. The liquid separator, the gas separator and several sets of hydraulic pumps are all located on the first mounting plate.

[0030] The frame is provided with a second mounting plate on the other side along its length, the second mounting plate and the air distributor are arranged opposite to each other, and the solenoid valve is provided on the second mounting plate;

[0031] The bottom of the frame is provided with a base plate, the air pump is located on the base plate, and the air storage tank is located on the base plate via a bracket.

[0032] Preferably, the liquid separator and the gas separator are arranged at intervals along the width direction of the frame, and both are located on the side of the first mounting plate facing the interior of the frame.

[0033] Two sets of hydraulic pumps are arranged side by side on both sides of the first mounting plate, and all the hydraulic pumps in each set are spaced apart along the width of the frame.

[0034] It should be noted that an endoscope has three main cavities (water / air supply channel, suction channel, and auxiliary water supply channel), therefore, at least three hydraulic pumps are needed to clean one endoscope. The following explanation uses the cleaning of the three main cavities of one endoscope as an example:

[0035] The independent pulse irrigation cleaning device for endoscopes provided by this utility model involves placing the endoscope in the cleaning tank during cleaning. The three irrigation pipes of the three hydraulic pumps are connected one-to-one with the three main cavities of the endoscope, namely the water / air supply pipe, the suction pipe, and the auxiliary water supply pipe. The control device turns on the three hydraulic pumps, and the cleaning fluid in the cleaning tank flows into the three hydraulic pumps through the distributor. The three hydraulic pumps then pump the cleaning fluid to the three main cavities to achieve independent cleaning of each cavity.

[0036] In addition, during the independent cleaning process of each chamber, the control device turns on the air pump. The compressed gas generated by the air pump is input into the storage tank for energy storage. When the set energy storage time is reached, the control device opens the solenoid valve, and the compressed gas energy stored in the storage tank is released instantly. The powerful air shock wave mixes with the cleaning fluid at each three-way valve through the air distributor and pulses into each chamber of the endoscope. When the set flushing time is reached, the solenoid valve is closed to realize independent pulse-type circulation cleaning of each chamber.

[0037] In summary, the independent pulse irrigation and cleaning device for endoscopes provided by this utility model has the following beneficial effects:

[0038] (1) Independent cleaning of each cavity: Each cavity of the endoscope is equipped with an independent hydraulic pump to deliver cleaning fluid. The flow rate and pressure of each hydraulic pump can be precisely controlled for different pipe diameters and structures to avoid the problem of incomplete flushing of some cavities due to uneven pressure.

[0039] (2) Pulse-type circulating cleaning: By opening and closing the solenoid valve at regular intervals, a periodic high-frequency pulse airflow is formed, which is superimposed with the continuous cleaning fluid of the hydraulic pump to enhance the turbulence effect in the cavity, simulate the mechanical action of manual brushing, and improve the cleaning effect of each cavity.

[0040] (3) Strong compatibility: The flow rate of each cavity is controlled by adjusting the speed of each hydraulic pump to adapt to endoscope chambers of different diameters, that is, it is compatible with different models of endoscopes. Attached Figure Description

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0053] The core of this invention is to provide an independent pulse irrigation cleaning device for endoscopes. This cleaning device performs pulsed circulation cleaning on each cavity of the endoscope independently, which can greatly improve cleaning efficiency and effect. In addition, the flow rate of each cavity can be adjusted, and it can be compatible with different models of endoscopes.

[0054] Please refer to Figure 1 , Figure 2 and Figure 3 This application provides an independent pulse irrigation cleaning device for endoscopes, including a cleaning tank 1, a liquid separator 3, an air pump 4, an air storage tank 5, an air distributor 6, at least three hydraulic pumps 9, and a control device.

[0055] Cleaning tank 1 is used to hold cleaning solution.

[0056] The inlet end of the separator 3 is connected to the drain outlet 1a of the cleaning tank 1, and the outlet end of the separator 3 branches out into at least three outlet pipes II.

[0057] At least three hydraulic pumps 9, each hydraulic pump 9 having an inlet connected to an outlet pipe II, and each hydraulic pump 9 having an outlet connected to an irrigation pipe III, the irrigation pipe III being used to connect to a cavity of the endoscope.

[0058] Air pump 4 is used to generate compressed air, and the outlet of air pump 4 is connected to the inlet of air storage tank 5.

[0059] The gas distributor 6 has its inlet end connected to the outlet of the gas storage tank 5 via a solenoid valve 7. The outlet end of the gas distributor 6 branches out into at least three outlet pipes V, and each outlet pipe V is connected to an irrigation pipe III via a three-way valve 10.

[0060] The control device signals are connected to all hydraulic pumps 9 and solenoid valves 7.

[0061] It should be noted that the endoscope has a complex tubular structure, including three main cavities: a water / air supply channel, a suction channel, and a secondary water supply channel. Therefore, at least three hydraulic pumps are needed to clean one endoscope.

[0062] The function of hydraulic pump 9 is to pump the mixed gas and liquid through the perfusion pipe VI to the various cavities of the endoscope. Hydraulic pump 9 can be a gear pump, vane pump, or plunger pump; the type is not unique and can be selected according to the actual situation.

[0063] The function of air pump 4 is to generate compressed air and input the compressed air into air storage tank 5 for energy storage. Air pump 4 can be a vacuum pump, compressed air pump 4, or turbocharger; the type is not unique and can be selected according to actual needs.

[0064] The control unit is used to manage and regulate the operation of other components (such as hydraulic pump 9 and solenoid valve 7) to automate the cleaning equipment.

[0065] like Figure 4As shown, taking the independent cleaning of one cavity of an endoscope by a hydraulic pump 9 as an example, the connection relationship of each component is explained. Specifically, the drain outlet 1a of the cleaning tank 1 is connected to the inlet of the distributor 3 through the first pipeline I. The outlet of the distributor 3 branches off into an outlet pipeline II, which is connected to the inlet of the hydraulic pump 9. The outlet of the hydraulic pump 9 is connected to one cavity of the endoscope through the irrigation pipeline III. The outlet of the air pump 4 is connected to the air tank 5 through the second pipeline (not shown). The air tank 5 is then connected to the inlet of the air distributor 6 through the third pipeline IV. A solenoid valve 7 or an air filter 8 as described below is installed on this third pipeline IV. An outlet pipeline V branches off from the outlet of the air distributor 6 and is connected to the irrigation pipeline III through a three-way valve 10.

[0066] The following explanation uses the cleaning of the three main cavities of an endoscope as an example: During cleaning, the endoscope is placed in the cleaning tank, and the three irrigation pipes of the three hydraulic pumps are connected to the three main cavities of the endoscope, namely the water / air supply pipe, the suction pipe, and the auxiliary water supply pipe. The control device turns on the three hydraulic pumps 9, and the cleaning fluid in the cleaning tank 1 flows into the three hydraulic pumps 9 through the distributor 3. The three hydraulic pumps 9 pump the cleaning fluid to the three main cavities to achieve independent cleaning of each chamber.

[0067] In addition, during the independent cleaning process of each chamber, the control device turns on the air pump 4. The compressed gas generated by the air pump 4 is input into the storage tank for energy storage. When the set energy storage time is reached, the control device turns on the solenoid valve 7, and the compressed gas energy stored in the air tank 5 is released instantly. The powerful air shock wave is mixed with the cleaning fluid at each three-way valve 10 through the air distributor 6 and pulsed into each chamber of the endoscope. When the set one flushing time is reached, the solenoid valve 7 is closed to realize that each chamber can be independently pulsed and circulated for cleaning.

[0068] In summary, the independent pulse irrigation and cleaning device for endoscopes provided in the above embodiments has the following effects:

[0069] First, each cavity is cleaned independently: each cavity of the endoscope is equipped with an independent hydraulic pump 9 to deliver cleaning fluid. The flow rate and pressure of each hydraulic pump 9 can be precisely controlled for different pipe diameters and structures to avoid the problem of incomplete flushing of some cavities due to uneven pressure.

[0070] Second, pulse-type circulating cleaning: by opening and closing the solenoid valve 7 at regular intervals, periodic high-frequency pulse airflow is formed, which is superimposed with the continuous cleaning fluid of the hydraulic pump 9 to enhance the turbulence effect in the cavity, simulate the mechanical action of manual brushing, and improve the cleaning effect of each cavity.

[0071] Third, it has strong compatibility: the flow rate of each cavity is controlled by adjusting the speed of each hydraulic pump 9 to adapt to endoscope chambers of different diameters, that is, it is compatible with different models of endoscopes.

[0072] It should be explained that the aforementioned pulsed irrigation refers to the generation of turbulence through periodic pressure fluctuations (such as the coordinated action of hydraulic pump 9 and air pump 4), which can enhance the scouring force and simulate the effect of manual scrubbing.

[0073] The aforementioned turbulence effect refers to the vortex motion formed by fluid in a non-laminar state within a pipe, which can improve the efficiency of pollutant removal.

[0074] Based on the above embodiments, as a further preferred embodiment, a first pressure sensor is provided on the connecting pipe between the gas outlet of the gas storage tank 5 and the solenoid valve 7, and a second pressure sensor is provided on the connecting pipe between each three-way valve 10 and the gas inlet liquid interface 21. Both the first pressure sensor and the second pressure sensor are signal connected to the control device.

[0075] The first pressure sensor monitors the gas pressure stored in the gas tank 5 in real time and transmits the data to the control device, which presets a first pressure threshold (e.g., 100 kPa). The second pressure sensor monitors the gas-liquid pressure in each cavity of the endoscope in real time and transmits the data to the control device, which presets a second pressure threshold (e.g., 10 kPa). In addition, the control device presets the cycle time for completing the cyclic pulse cleaning.

[0076] Therefore, the specific steps of independent pulse circulation cleaning will be explained using the cleaning of one chamber in an endoscope as an example:

[0077] Step 1: Turn on hydraulic pump 9 to clean the endoscope chamber;

[0078] Step 2: Determine if the loop time has been reached. If yes, proceed to Step 3 below; otherwise, proceed to Step 4 below.

[0079] Step 3: Turn off hydraulic pump 9, air pump 4 and solenoid valve 7. Pulse cleaning ends.

[0080] Step 4: Turn on air pump 4;

[0081] Step 5: Obtain the air pressure value of the first pressure sensor and determine whether the air pressure value reaches the preset first pressure threshold (e.g., 100 kPa). If yes, proceed to step 6 below; otherwise, continue to step 5.

[0082] Step 6: Open solenoid valve 7;

[0083] Step 7: Obtain the air pressure value of the second pressure sensor and determine whether the air pressure value has dropped to the preset second pressure threshold (e.g., 10 kPa). If yes, close the solenoid valve 7 and execute the above step 5. If no, execute the following step 8.

[0084] Step 8: Determine if the loop time has been reached. If yes, proceed to step 3; otherwise, proceed to step 7.

[0085] Therefore, by monitoring the pressure and flow data in real time through the first and second pressure sensors, the control device can dynamically adjust the opening and closing sequence of the hydraulic pump 9, the air pump 4 and the solenoid valve 7 to more accurately control the flushing of the endoscope cavity, thereby ensuring thorough flushing of the endoscope cavity and preventing damage to the endoscope due to sudden pressure changes.

[0086] It should be noted that when cleaning two or more endoscopes at the same time, due to the complex connection of the various functional tubes, medical staff need to spend a lot of time and effort to correctly connect each tube, which can easily lead to connection errors, causing the irrigation and cleaning work to be unable to be carried out normally, and may even damage the endoscope equipment.

[0087] To solve the above problems, please refer to the following embodiments based on the above examples: Figure 2 and Figure 3 As a further preferred option, the device also includes an irrigation assembly 2, which includes several sets of air-liquid inlets and several sets of air-liquid outlets, and several sets of hydraulic pumps 9, each set of hydraulic pumps including at least three hydraulic pumps 9.

[0088] Each set of air-liquid inlets includes at least three air-liquid inlets 21, and each air-liquid inlet 21 is connected to an irrigation pipe III.

[0089] Each set of gas-liquid interfaces includes at least three gas-liquid interfaces 22, each gas-liquid interface 22 is connected to a gas-liquid interface 21, and is also used to connect to a cavity of the endoscope.

[0090] Therefore, in use, a set of air-liquid inlet ports, a set of air-liquid outlet ports, and a set of hydraulic pumps work together to clean one endoscope. Two or more endoscopes are placed in the cleaning tank 1. The three main channels of each endoscope—water / air supply pipe, suction pipe, and auxiliary water supply pipe—are connected via flexible hoses to the three air-liquid outlet ports 22 in each set of air-liquid outlet ports. The three air-liquid inlet ports 21 in the corresponding set of air-liquid inlet ports are then connected to the three irrigation pipes III of a hydraulic pump 9, thus enabling the cleaning of one endoscope. Therefore, the irrigation assembly 2 not only facilitates operator access but also allows for the simultaneous cleaning of two or more endoscopes, significantly improving cleaning efficiency.

[0091] Based on the above embodiments, please refer to Figure 2 and Figure 3 Considering the specific configuration of the irrigation component 2, as a further preferred option, the irrigation component 2 is located at the bottom of the cleaning tank 1, and all the air-liquid inlet ports 21 in the irrigation component 2 extend through the bottom of the cleaning tank 1 and out of the cleaning tank 1.

[0092] Understandably, since the cleaning tank 1 contains the cleaning fluid, placing the endoscope in the cleaning tank 1 during cleaning can clean the endoscope's outer shell, further improving the cleaning effect. The perfusion assembly 2 acts as a bridge connecting the various cavities of the endoscope to the hydraulic pump 9, its function being to perfuse the mixed gas-liquid mixture into each cavity of the endoscope. The perfusion assembly 2 is located in the cleaning tank 1, facilitating the connection between the various cavities of the endoscope and the gas-liquid outlet 22.

[0093] In addition, all the air-liquid inlets 21 in the irrigation assembly 2 extend through the bottom of the cleaning tank 1, which facilitates the connection between the air-liquid inlets 21 and the outlet pipe of the hydraulic pump 9.

[0094] Based on the above embodiments, the irrigation component 2 is further optimized. For further preferred embodiments, please refer to... Figure 2 and Figure 3 Each set of air-liquid inlets also includes a side-leak air inlet 23, which extends beyond the bottom of the cleaning tank 1. Each set of air-liquid outlets also includes a side-leak air outlet 24, which connects to the side-leak air inlet 23 and is used to connect to the side-leak outlet of the endoscope.

[0095] In other words, the irrigation assembly 2 has at least two pairs of connected side-leak inlet ports 23 and side-leak outlet ports 24. The side-leak inlet ports 23 extend through the bottom of the cleaning tank 1 for easy connection to the leak detector, and the side-leak outlet ports 24 connect to the side-leak port of the endoscope. Thus, during endoscope cleaning, while the endoscope is immersed in the cleaning solution, the leak detector's vent valve can be tightened and pressure injected to observe whether bubbles emerge. If bubbles emerge, it indicates that the endoscope is leaking and should be sent for repair and inspection immediately. If no bubbles emerge, it indicates that the endoscope is working normally.

[0096] Based on the above embodiments, as a further preferred embodiment, at least three air-liquid inlets 21 in each group of air-liquid inlets have different text labels, such as liquid delivery / air pipeline liquid delivery inlet 21a, suction pipeline liquid delivery inlet 21b, and auxiliary liquid delivery pipeline liquid delivery inlet 21c, for example... Figure 5 As shown; at least three gas-liquid interfaces 22 in each group of gas-liquid interfaces have different text labels, such as liquid / gas delivery pipe interface 22a, suction pipe interface 22b, and auxiliary liquid delivery pipe interface 22c, as shown. Figure 6 As shown, this makes it easier for operators to distinguish between them.

[0097] Based on the above embodiments, as a further preferred option, please refer to... Figure 1 and Figure 4 The cleaning equipment also includes an air filter 8, which is located on the connecting pipe between the solenoid valve 7 and the air distributor 6.

[0098] It should be noted that the cleaning solution usually uses a special multi-enzyme cleaning solution or sterile water to remove stubborn contaminants such as blood and mucus adhering to the endoscopic cavity.

[0099] The air filter 8 filters dust and particles from the air. It is installed on the connecting pipe between the solenoid valve 7 and the air distributor 6. It filters the air before it enters the cleaning fluid to form a clean gas-liquid mixture, thereby preventing airborne contaminants from remaining in the endoscope cavity and affecting the cleaning effect.

[0100] For a more preferred embodiment, please refer to Figure 4 A first one-way valve 11 is provided on the connecting pipe between the air filter 8 and the air distributor 6. The first one-way valve 11 ensures that the air flows only towards the air distributor 6, which can prevent the air backflow from affecting the stability of the air tank 5 and the air pump 4, and can also ensure that the clean air flows normally to the three-way valve 10 to mix with the cleaning liquid.

[0101] In addition, please refer to Figure 4 A second check valve 12 is installed on the connecting pipe between the outlet of each hydraulic pump 9 and the three-way valve 10. The second check valve 12 ensures that the cleaning fluid flows only towards the three-way valve 10, which can prevent the cleaning fluid from flowing back and affecting the stability of the distributor 3 and the hydraulic pump 9, and can also ensure that the cleaning fluid flows normally to the three-way valve 10 to mix with the cleaning air.

[0102] Based on the above embodiments, as a further preferred option, please refer to... Figure 1 and Figure 3 The cleaning equipment also includes a frame 13, with an opening at the top of the frame 13, and a cleaning tank 1 is disposed in the opening.

[0103] A first mounting plate 14 is provided on one side of the frame 13 along its length direction. The first mounting plate 14 is located near the bottom of the cleaning tank 1. The liquid separator 3, the gas separator 6 and several sets of hydraulic pumps are all located on the first mounting plate 14.

[0104] A second mounting plate 15 is provided on the other side of the frame 13 along its length direction. The second mounting plate 15 and the air distributor 6 are arranged opposite each other, and the solenoid valve 7 is provided on the second mounting plate 15.

[0105] The bottom of the frame 13 is provided with a base plate 16, the air pump 4 is provided on the base plate 16, and the air storage tank 5 is vertically provided on the base plate 16 through a bracket.

[0106] As can be seen from the above structure, the cleaning tank 1 of this application and the irrigation components 2, liquid distributor 3, air pump 4, air distributor 6 and several sets of hydraulic pumps at its bottom wall are concentrated in the frame 13, which can save the floor space of the cleaning equipment, facilitate overall management and transportation, and the frame 13 has excellent structural strength, which can enhance the stability of the cleaning equipment.

[0107] In addition, the cleaning tank 1 is located in the opening at the top of the frame 13. The liquid distributor 3, the air distributor 6, and several sets of hydraulic pumps are centrally located on one side plate of the frame 13, and the solenoid valve 7 is located on the other side plate of the frame 13. The air pump 4 and the air tank 5 are both located on the bottom plate 16 of the frame 13. This arrangement, with the liquid distributor 3, the air distributor 6, and several sets of hydraulic pumps concentrated on one side, facilitates the connection between them and is rationally laid out. It also allows the cleaning fluid in the cleaning tank 1 to flow from top to bottom into the hydraulic pump 9, and the compressed air in the air tank 5 to flow from bottom to top into the air distributor 6, thereby enabling the cleaning fluid and compressed air to mix quickly, which is beneficial to improving the cleaning efficiency of the endoscope.

[0108] Based on the above embodiments, as a further preferred option, please refer to... Figure 1 The air inlet of the air tank 5 is located at its bottom end, and the air outlet of the air tank 5 is located at its top end. The air tank 5 is set vertically, and there is a gap between the bottom end of the air tank 5 and the base plate 16. This gap provides a space for the connecting pipe between the air outlet of the air pump 4 and the bottom end of the air tank 5.

[0109] Therefore, the air tank 5 is designed with bottom inlet and top outlet. Air enters from the bottom of the air tank 5, which can first flush out the air remaining at the bottom and avoid creating dead corners at the bottom of the air tank 5, thereby maximizing the utilization of the volume of the air tank 5.

[0110] Based on the above embodiments, as a further preferred option, please refer to... Figure 3 Several sets of air-liquid inlets are arranged at intervals along the length of the frame 13, and all air-liquid inlets 21 in each set are arranged at intervals along the width of the frame 13. This facilitates the orderly arrangement of pipelines between each air-liquid inlet 21 and the outlet of the hydraulic pump 9 by the operator, avoiding a messy arrangement.

[0111] For further optimization, please refer to... Figure 3 The liquid separator 3 and the gas separator 6 are arranged at intervals along the width direction of the frame 13, and both are located on the side of the first mounting plate 14 facing the inside of the frame 13. This facilitates the arrangement of pipelines between the liquid separator 3 and the drain outlet 1a of the cleaning tank 1, and between each hydraulic pump 9, as well as between the gas separator 6 and the air filter 8, and between the outlet pipelines of each hydraulic pump 9.
