[0002] The operating room is an important place for aseptic operation in medical institutions, and the cleanliness of its environment is crucial to the success rate of surgery and the recovery of patients. Before surgery, medical staff need to perform strict hand cleaning and disinfection to avoid bacterial contamination of the surgical area. Traditional hand washing basins are designed for manual operation, which has a certain risk of contact infection and cannot fully meet the high standard of aseptic requirements in modern operating rooms.

[0003] In recent years, with the development of induction technology, non-contact induction equipment has been widely used in the medical field. The induction type hand washing basin realizes automatic control of water flow through infrared or other sensing technology, without manual operation, thereby effectively avoiding secondary pollution. In addition, some induction hand washing basins also integrate intelligent temperature control, time setting, automatic proportioning of disinfectant, etc., further improving the convenience and safety of use.

[0004] However, in actual use, after the disinfectant or deep cleaning hand sanitizer is dispensed, liquid droplets are formed at the mouth due to gravity, which causes waste and increases the cleaning workload. After the residual liquid drops out, the hand sanitizer exposed to the air for a long time may form a solid material at the outlet due to the volatilization or oxidation of its chemical components. This not only affects the normal dispensing of the hand sanitizer, but also may block the dispensing outlet, causing the equipment to malfunction. SUMMARY

[0036] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0037] Reference Figures 1-6 A surgical operating room induction hand washing pool, comprising:

[0038] A table body 100;

[0039] A pool body 101 arranged in the table body 100;

[0040] A water outlet pipe 102 arranged on the table body 100, one end of the water outlet pipe 102 facing the pool body 101;

[0041] A liquid tank 103 arranged in the table body 100, used for storing hand washing liquid;

[0042] A liquid pipe 104 arranged on the liquid tank 103, one end of the liquid pipe 104 extending into the water outlet pipe 102 through the table body 100 and corresponding to the water outlet of the water outlet pipe 102;

[0043] An induction component arranged on the table body 100, used for monitoring the entry of a shielding object into the pool body 101;

[0044] A conveying component arranged between the liquid tank 103 and the liquid pipe 104, used for conveying the hand washing liquid in the liquid tank 103 into the liquid pipe 104;

[0045] A control component arranged between the liquid tank 103 and the water outlet pipe 102, used for controlling the opening and closing of the water outlet pipe 102 and the start and stop of the conveying component, the control component being capable of opening the water outlet pipe 102 and continuously operating for a preset time, and simultaneously starting the conveying component and operating for a preset time when the induction component monitors the entry of the shielding object into the pool body 101;

[0046] By setting the liquid tank 103, medical staff can add an appropriate amount of hand sanitizer to the liquid tank 103, and the liquid tank 103 stores the hand sanitizer for subsequent use. In the application process, the sensing component is used to monitor the state of the pool body 101 to detect whether the hands of medical staff or other medical equipment enter the pool body 101. When the sensing component detects that the hands of medical staff or other medical equipment enter the pool body 101, the control component will start, and the water outlet pipe 102 will be opened according to the preset time a, and the conveying component will be started at the same time, and the conveying component will convey the hand sanitizer to the water outlet of the water outlet pipe 102, and the conveying time is also the preset time a, which ensures the automatic output of the appropriate amount of hand sanitizer.

[0047] The end of the liquid pipe 104 extends into the water outlet pipe 102 and corresponds to the water outlet of the water outlet pipe 102. When the water outlet pipe 102 is opened, water will be discharged from the water outlet of the water outlet pipe 102, and when the conveying component conveys the hand sanitizer into the liquid pipe 104, the hand sanitizer will also be discharged from the water outlet of the water outlet pipe 102. In this way, the system can automatically provide an appropriate amount of water flow and hand sanitizer each time the medical staff uses the hand washing pool. In addition, the sensing component can monitor in real time whether an object (such as a hand or a medical instrument) enters the pool body 101. Only when the sensing component senses that the hand or the instrument enters the pool body 101, the control component will start the water outlet pipe 102 and the conveying component, thereby avoiding unnecessary waste of water and hand sanitizer, and also avoiding direct contact between the medical staff and the device before, during and after washing hands, thereby reducing the risk of cross contamination.

[0048] Further, in order to effectively avoid the hand sanitizer from being left over and wasted during use, one end of the liquid pipe 104 is arranged in the water outlet pipe 102, and the end of the liquid pipe 104 corresponds to the end of the water outlet pipe 102. When the water outlet pipe 102 is opened and the hand sanitizer is conveyed into the liquid pipe 104, the water flow in the water outlet pipe 102 directly contacts the hand sanitizer. By using the pressure of the water outlet of the water outlet pipe 102, the water flow can impact the hand sanitizer and scatter it into foam, which then forms foam and flows into the pool body 101, ensuring that the hand sanitizer can uniformly and effectively cover the hands of medical staff each time it is used. This design not only improves the utilization efficiency of the hand sanitizer and avoids liquid residue and waste, but also improves the cleaning effect of the hand sanitizer through foaming. Since the foam can spread and cover a larger area when it contacts the skin, it ensures more thorough cleaning and disinfection.

[0049] The hand sanitizer is discharged in the form of foam, which can reduce the risk of pollution caused by liquid droplets and improve the user experience. Moreover, when the water flow passes through the end of the liquid pipe 104, it also flushes the end of the liquid pipe 104, further avoiding the residue of the liquid at the outlet. Through the impact of the water flow of the water outlet pipe 102, the hand sanitizer that may be left at the end of the liquid pipe 104 can be effectively removed, preventing liquid droplets from being left at the mouth. In this way, the phenomenon of liquid droplets falling around the device due to gravity is avoided, reducing the waste of hand sanitizer and reducing the workload of subsequent cleaning.

[0050] It is worth noting that the control component can be set to sense that the sensing component senses the object again within the preset time A after initially sensing the object, and the conveying component no longer conveys the hand sanitizer into the liquid pipe 104. This avoids releasing hand sanitizer again when rinsing hands after using hand sanitizer, which ensures that hand sanitizer is released strictly according to demand each time, avoids excessive consumption of hand sanitizer, and improves the efficiency and economy of the device.

[0051] Further, when the sensing component senses the object again after the preset time A after initially sensing the object, the control component will restart the water outlet pipe 102 according to the preset time a and start the conveying component. At this time, the conveying component will re-convey the hand sanitizer to the water outlet of the water outlet pipe 102 to ensure that medical personnel can obtain the appropriate amount of hand sanitizer at the right time. This design makes the delivery of hand sanitizer more intelligent and avoids repeated and ineffective liquid delivery. The preset time a is 5 seconds and the preset time A is 6 minutes. The purpose of setting the preset time a and the preset time A is to achieve more accurate and intelligent control of the release of hand sanitizer, avoid waste, and ensure that medical personnel obtain the appropriate amount of hand sanitizer at the right time. The preset time A (6 minutes): This is a longer delay set to avoid frequent release of hand sanitizer in a short period of time. That is, when the sensing component initially senses the hands or other objects of medical personnel, a 6-minute time window is set. If the hands or other objects are sensed again within this time period, the device will not continue to deliver hand sanitizer.

[0052] The purpose of this is to prevent medical staff from repeatedly obtaining hand sanitizer within a short time after washing their hands, causing waste of hand sanitizer. A sufficient window period can be provided for medical staff to clean their hands during this time. The preset time a (5 seconds): this is to control the delivery time of hand sanitizer each time. When the sensing component detects that the hand or other objects enter the pool body 101 again, the control component will open the water outlet pipe 102 and deliver the hand sanitizer within the preset time a (such as 5 seconds). This is to ensure that the hand sanitizer released each time is accurate and does not flow excessively, avoiding waste. If the medical staff moves the hand washing site due to other factors during hand washing, and exceeds the preset time A (6 minutes), the system will automatically reset. When the medical staff returns to the hand washing pool and the hand or other objects are sensed again, the system will restart the hand sanitizer release operation, ensuring that the next hand washing process still meets the standard and is not affected by the previous operation.

[0053] By setting the preset time A and the preset time a, the device can realize intelligent control, ensuring that each release of hand sanitizer is strictly on demand, avoiding unnecessary waste. In addition, this design enhances the adaptability of the device, which can flexibly cope with different use scenarios, such as when medical staff needs to move positions or change actions during hand washing, the system can still provide accurate liquid delivery.

[0054] As a further aspect of the present application, the sensing component includes a boss 200 connected to the table body 100, the water outlet pipe 102 passes through the boss 200, the boss 200 provides support for the water outlet pipe 102, the boss 200 is provided with a photoelectric sensor emitting end 201, the table body 100 is provided with a photoelectric sensor receiving end 202, the water outlet pipe 102 is provided with an electromagnetic valve 203, and the liquid tank 103 is provided with a controller 204.

[0055] By setting the photoelectric sensor, the emitting end emits a light beam outward. If an object (such as a hand or a medical instrument) enters the pool body 101 and blocks the light beam, the receiving end cannot receive the light signal from the emitting end. At this time, the photoelectric sensor sends a signal to the controller 204, and the controller 204 receives the signal and immediately triggers the opening of the electromagnetic valve 203, and then opens the water outlet pipe 102. When the electromagnetic valve 203 is opened, the hand sanitizer in the liquid tank 103 is delivered to the water outlet pipe 102 through the liquid pipe 104, so that the water is sensed and discharged during hand washing, avoiding the problem of cross contamination caused by touching other components during hand washing.

[0056] It is worth mentioning that the controller 204 is connected with the photoelectric sensor and the electromagnetic valve 203 through signal lines and power lines to ensure the coordinated work of various components. The transmitting end and the receiving end of the photoelectric sensor are respectively installed on the boss 200 and the table body 100, and they are connected with the controller 204 through cables to transmit the signal of the object blocking the light beam. The electromagnetic valve 203 is connected with the controller 204 through wires, and after the controller 204 receives the signal from the photoelectric sensor, the controller 204 sends a command to the electromagnetic valve 203 to open the electromagnetic valve 203 and make the water flow and the hand sanitizer in the water outlet pipe 102 flow out smoothly.

[0057] Further, the controller 204 can also be provided with a preset time a (5 seconds), which is used to ensure the accurate control of the release time of the hand sanitizer each time. When the light beam emitted by the transmitting end 201 of the photoelectric sensor is blocked by an object (such as a hand or a medical instrument), the receiving end cannot receive the optical signal, triggering the controller 204 to receive the signal and start timing. The timer in the controller 204 starts timing, and the set time a is 5 seconds. The controller 204 will keep the electromagnetic valve 203 open, and will control the delivery component to deliver the hand sanitizer to the water outlet pipe 102. The delivery process will last for 5 seconds to ensure that an appropriate amount of hand sanitizer can be delivered to the water outlet. In the 5-second time, the hand sanitizer flows out through the water outlet pipe 102 together with the water flow to provide sufficient cleaning and disinfection in the sink. After the 5-second timing is over, the controller 204 will automatically send a signal to close the electromagnetic valve 203 to stop delivering the hand sanitizer, so as to prevent waste and ensure the accurate control of the amount used each time. By setting the preset time a (5 seconds), the over-consumption and invalid output of the hand sanitizer can be effectively avoided, and the use efficiency of the hand sanitizer can be improved.

[0058] As a further embodiment of the present application, the delivery component comprises a push plate 300 arranged in the liquid tank 103, and an electric push rod 301 connected in the liquid tank 103, and the telescopic shaft of the electric push rod 301 is connected with the push plate 300.

[0059] By setting the push plate 300, the hand sanitizer is located between the push plate 300 and the bottom end of the liquid pipe 104, and the telescopic shaft of the electric push rod 301 is connected with the push plate 300. When the controller 204 receives the signal from the photoelectric sensor and triggers the electromagnetic valve 203 to open, the controller 204 controls the action of the electric push rod 301 at the same time. The electric push rod 301 starts to extend, and the push plate 300 drives the hand sanitizer to be pushed along the liquid pipe 104 to the water outlet pipe 102 under the drive of the electric push rod 301. When the electric push rod 301 pushes the push plate 300 to move downward, the hand sanitizer is pushed to the outlet of the liquid pipe 104, and finally flows out through the water outlet pipe 102. This design ensures the stable delivery and accurate control of the liquid, avoiding the excessive delivery or waste of the hand sanitizer caused by uneven external pressure or manual operation error. It is worth noting that the electric push rod 301 moves the push plate 300 from the upper limit position to the lower limit position, and the process takes a preset time a (5 seconds). When the controller 204 receives the signal from the photoelectric sensor and triggers the electromagnetic valve 203 to open, the electric push rod 301 completes the pushing action of the push plate 300 within 5 seconds. This process avoids the excessive release or unstable flow of the hand sanitizer during the delivery process through accurate time control, effectively ensuring the use efficiency of the hand sanitizer and reducing waste.

[0060] It is worth noting that within the preset time A (6 minutes) after the first detection of the hand or other objects, the controller 204 will continuously listen to the signal of the sensing component. When the hand is detected again, the controller 204 will instruct the electromagnetic valve 203 to open for one minute, providing enough time for the medical staff to wash the residual hand sanitizer on their hands. At the same time, the controller 204 will also control the telescopic shaft of the electric push rod 301 to retract, pushing the push plate 300 to move back, preparing for the next delivery of the hand sanitizer. At this time, the retraction action of the electric push rod 301 will last for a short time to ensure that the push plate 300 completely returns to its initial position. If the sensing component does not detect the object again at the preset time A (6 minutes) + 1 second after the first detection of the hand or other objects, the controller 204 will consider that the current hand washing operation has been completed, and automatically execute the action of returning to the standby state. At this time, the controller 204 will issue an instruction to control the telescopic shaft of the electric push rod 301 to reset the push plate 300 to the starting position of the liquid tank 103, preparing for the next hand washing operation.

[0061] During the process, the action of the electric push rod 301 is accurately controlled by the controller 204, ensuring that the device can be fully restored after each use, avoiding unnecessary waste caused by operation errors or long-term non-use of the device. At the same time, the intelligent adjustment of the controller 204 ensures that each release and push operation of the hand sanitizer meets the expected time length and flow, avoiding waste or overuse. Through this design, the device can maximize the use efficiency of hand sanitizer without affecting the operation efficiency, and ensure that the device can quickly respond at the next use, providing better experience for medical staff.

[0062] As a further aspect of the present application, the top of the liquid tank 103 is connected with a liquid injection channel 302, the liquid injection channel 302 is provided with a sealing plug 303, the end of the liquid injection channel 302 extends to the position below the push plate 300 through the liquid tank 103 and the push plate 300, the push plate 300 is provided with a first opening 304, the first opening 304 is provided with a first baffle 305, and the first baffle 305 is connected with a first spring 306 between the first opening 304 and the first baffle 305.

[0063] By setting the first opening 304, the first baffle 305 and the first spring 306, the first opening 304 can form a one-way air valve, when the push plate 300 moves downward, the first baffle 305 can close the first opening 304 to block the outflow of gas, at this time, the liquid tank 103 will generate positive pressure, the pressure can make the liquid enter the liquid pipe 104 to realize the pushing of the liquid.

[0064] As a further aspect of the present application, the inside bottom surface of the liquid tank 103 is connected with a connecting pipe 307 in communication with the liquid pipe 104, a plurality of second openings 308 are formed in the outer wall of the connecting pipe 307, a baffle ring 309 is arranged in the connecting pipe 307, a second baffle 310 is slidably connected in the baffle ring 309, a first limiting rod 311 is connected to the top of the second baffle 310, a second limiting rod 312 is slidably connected to the first limiting rod 311 on the inside top surface of the connecting pipe 307, and a second spring 313 is connected between the second limiting rod 312 and the first limiting rod 311.

[0065] By setting the first limiting rod 311 and the second limiting rod 312, a stable check mechanism is formed in the connecting pipe 307 of the liquid tank 103, which can effectively limit the moving position of the second baffle 310. Specifically, when the liquid soap is in the normal conveying process, the push plate 300 pushes the liquid to be conveyed into the liquid pipe 104, and the second baffle 310 moves upward under the action of the liquid pressure and overcomes the elastic force of the second spring 313, and the liquid smoothly enters the liquid pipe 104 through the second opening 308. When the push plate 300 is reset upward, due to the negative pressure generated in the liquid tank 103 caused by the movement of the push plate 300, the second baffle 310 in the connecting pipe 307 moves downward under the action of the second spring 313 and cooperates with the blocking ring 309, thereby effectively blocking the backflow of the liquid soap in the liquid pipe 104 due to the negative pressure. The sliding cooperation structure of the first limiting rod 311 and the second limiting rod 312 makes the second baffle 310 always remain in a reasonable activity range.

[0066] The elastic reset force provided by the second spring 313 ensures that the second baffle 310 quickly returns to the initial position after the liquid pressure and the reset action are completed, avoiding the occurrence of backflow problems caused by improper baffle position. At the same time, the multiple second openings 308 provided on the outer wall of the connecting pipe 307 provide multiple channels for the flow of the liquid, effectively reducing the flow resistance of the liquid when passing through the connecting pipe 307, and ensuring that the liquid soap can be smoothly and efficiently conveyed into the liquid pipe 104. This design prevents the liquid soap in the liquid pipe 104 from flowing back to the liquid tank 103 due to negative pressure after the push plate 300 completes each liquid conveying action, ensures the stability of the liquid soap in the liquid pipe 104, avoids the problem of insufficient or intermittent output of liquid soap caused by liquid backflow, and improves the use reliability and conveying accuracy of the equipment.

[0067] As a further embodiment of the present application, the end of the water outlet pipe 102 is connected with a bubbler 105.

[0068] By setting the bubbler 105, the liquid is fine foam when flowing through the end of the water outlet pipe 102 through the action of the bubbler 105. Specifically, the inside of the bubbler 105 is provided with multiple layers of filter screen and micro-porous structure, the liquid from the water outlet pipe 102 flows out when the liquid pipe 104 gushing out of the liquid soap produces high-speed impact, the mixing of the two liquid streams enhances the primary emulsification effect of the liquid, and the air mixing degree of the liquid soap is improved. The mixed liquid flows through the bubbler 105, and the multiple layers of filter screen and micro-porous structure of the bubbler 105 further refine the liquid into foam, and finally output from the liquid outlet. This structure realizes more efficient mixing of liquid soap through liquid impact, not only strengthens the foaming effect of the bubbler 105, but also makes the generated foam more delicate, uniform, and stronger in coverage. In addition, the liquid intersection position between the water outlet pipe 102 and the liquid pipe 104 is designed to be close to the inlet of the bubbler 105, ensuring that the mixed liquid directly enters the bubbler 105 for secondary processing, reducing the resistance and mixing loss in the liquid flow path.

[0069] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
