Description

Technical Field

[0001] The present invention relates to the technical field of medical cleaning and disinfecting equipment, and in particular to a fully automatic hand-washing robot and a cleaning method. Background Art

[0002] Hand hygiene is a general term for hand washing, sanitary hand disinfection and surgical hand disinfection. It is mainly a measure taken to address the risk of cross infection in the work of medical staff. It is an important means of hospital infection control. Hand hygiene can effectively reduce hospital infections. Among them, surgical hand disinfection (also known as preoperative disinfection) refers to the process in which medical staff thoroughly wash their hands, nails, forearms and upper arms with soap (liquid) or antibacterial soap (liquid) and running water before surgery, and then use hand disinfectant to remove or kill temporary and permanent bacteria on the hands. This process can effectively reduce the risk of wound infection during surgery and thus shorten the wound healing time. The surgical hand disinfection process on the existing market is that the surgeon manually rubs and rinses his hands, forearms to the lower 1 / 3 of the upper arm with running water, and then uses hand disinfectant to kill the bacterial flora in this area. This process takes 10-15 minutes, has complicated steps, is time-consuming and labor-intensive, and sometimes may not be thorough due to improper operation by the surgeon. Sometimes, when medical staff perform operations continuously, they consume a huge amount of energy, and hand hygiene cleaning will increase the burden on the user. Summary of the Invention

Figure 2 A three-dimensional diagram schematically showing a fully automatic hand washing robot according to an embodiment of the present invention, Figure 3 The structural diagram of the hand washing module according to one embodiment of the present invention is shown schematically. Figure 1-3 As shown, a fully automatic hand washing robot of the present invention comprises:

[0041] Hand washing module 10, lifting module 20, control module 30 and supply module 40;

[0042] The hand washing module 10 is connected to the supply module 40 by pipeline. The hand washing module 10 is used to wash hands, and the supply module 40 is used to provide cleaning materials for the hand washing module 10. The lifting module 20 is fixedly connected to the hand washing module 10. The lifting module 20 can reciprocate in the vertical direction to adjust the height of the hand washing module 10. The control module 30 is in communication with the hand washing module 10, the lifting module 20 and the supply module 40. The control module 30 is used for human-computer interaction and controlling the movements of the hand washing module 10, the lifting module 20 and the supply module 40;

[0043] The hand washing module 10 includes a first housing 101, an arm washing device 102, a finger washing device 103, a drying device 104, and a detection device 105. One end of the first housing 101 has a first opening 1011 for inserting the hand. The arm washing device 102 and the finger washing device 103 are arranged in the first housing 101, and the finger washing device 103 is arranged away from the first opening 1011.

[0044] The arm washing device 102 can move back and forth axially along the inner wall of the first shell 101. The arm washing device 102 and the finger washing device 103 are respectively connected to the supply module 40 pipeline. The detection device 105 is arranged on the side wall of the first shell 101. The detection device 105 is used to detect whether the hand is placed in place and whether the hand is cleaned to standard.

[0045] Specifically, the control module 30 is communicated with the hand washing module 10, the lifting module 20 and the supply module 40, and can realize the hand washing operation through automatic control, without the user having to rub and wash by hand, thus freeing the user's hands. At the same time, the lifting module 20 is fixedly connected to the hand washing module 10, and the lifting module 20 can move back and forth in the vertical direction, so that the height of the hand washing module 10 can be adjusted according to the height of the user, thereby facilitating use by people of different heights.

[0046] Two hand washing modules 10 can be provided, and the two hand washing modules 10 are spaced apart and arranged side by side, so as to wash both arms of the user at the same time and speed up the washing speed.

[0047] The hand washing module 10 has an arm washing device 102 and a finger washing device 103. The arm washing device 102 can move back and forth axially along the inner wall of the first shell 101 and can wash the user's arm. The finger washing device 103 is located at one end of the first shell 101. When the user's hand is inserted into the first shell 101, the finger part is located on the finger washing device 103. The finger washing device 103 can wash the user's fingers and nail crevices, making the cleaning of the user's hands more comprehensive and further reducing the retention of bacteria.

[0048] At the same time, the hand washing module 10 also has a detection device 105, which can detect whether the user's hands are placed in place. Only when the hands are detected to be in place will the hands be washed. At the same time, the detection device 105 can also perform bacterial detection on the hands after washing. When the total number of residual bacterial colonies meets the standard, it will be displayed that the cleaning is completed.

[0049] In this way, the hand washing robot of the present invention can achieve comprehensive cleaning and disinfection of fingers and arms, and can be applied to medical, sterile workshops, food and other industries that require hand disinfection and hand hygiene processes.

[0050] Furthermore, the lifting module 20 includes a first frame 201, a second frame 202 and an electric cylinder 203;

[0051] The first frame 201 is sleeved on the outer wall of the second frame 202. The electric cylinder 203 is disposed in the second frame 202, and one end of the electric cylinder 203 is fixedly connected to the bottom of the first frame 201. The electric cylinder 203 is used to perform telescopic movement to control the lifting and lowering of the first frame 201.

[0052] The hand washing module 10 is disposed transversely in the first frame 201 .

[0053] Specifically, the first frame 201 is sleeved on the second frame 202, and the hand washing module 10 is horizontally arranged in the first frame 201. When the electric cylinder 203 is extended or retracted, the first frame 201 will move toward the direction close to the second frame 202. If the first frame 201 drops excessively, the top of the second frame 202 will hit the hand washing module 10. Therefore, it is necessary to limit the numerical range of the extension and retraction of the electric cylinder 203. The lower limit of the numerical range can be set according to the average height of adult females, and the upper limit can be set according to the average height of adult males. The distance from the hand washing module 10 to the bottom of the first frame 201 is at least greater than the upper limit of the numerical range to prevent the second frame 202 from hitting the hand washing module 10.

[0054] Furthermore, the arm washing device 102 includes a washing ring 1021 , a sliding bracket 1022 and a first motor 1023 ;

[0055] The first motor 1023 is located at one end of the first housing 101 , and the sliding bracket 1022 is fixed in the first housing 101 , and the sliding bracket 1022 is arranged along the axial direction of the first housing 101 ;

[0056] The cleaning ring 1021 is sleeved on the sliding bracket 1022, and the cleaning ring 1021 is in transmission connection with the first motor 1023, and the first motor 1023 drives the cleaning ring 1021 to make axial reciprocating movement;

[0057] The cleaning ring 1021 has a first through hole 10211 extending axially therethrough and a second through hole 10212 extending radially therethrough. The first through hole 10211 is for a hand to pass through, and the second through hole 10212 is connected to a pipeline of the supply module 40 .

[0058] Specifically, the sliding bracket 1022 is axially arranged along the inner wall of the first shell 101, and multiple sliding brackets 1022 are evenly and spaced apart along the circumference of the first shell 101. The sliding bracket 1022 can be configured as a crossbar. When the multiple sliding brackets 1022 pass through the cleaning ring 1021, the cleaning ring 1021 is supported on the sliding bracket 1022. There is a certain distance between the cleaning ring 1021 and the inner wall of the first shell 101 to prevent the cleaning ring 1021 from scratching the first shell 101 during movement.

[0059] The first motor 1023 is in transmission connection with the cleaning ring 1021 . Specifically, the cleaning ring 1021 is sleeved on the transmission shaft of the first motor 1023 . The cleaning ring 1021 is threadedly connected to the transmission shaft. When the transmission shaft rotates, the cleaning ring 1021 moves axially.

[0060] An atomizing nozzle is installed on the second through hole 10212. When the second through hole 10212 is connected to the supply module 40, atomized liquid can be sprayed out to contact the surface of the hand faster and more comprehensively, thereby achieving rapid cleaning.

[0061] The first through hole 10211 of the cleaning ring 1021 can allow the hand to pass through. When cleaning, the cleaning ring 1021 moves axially back and forth, so that the second through hole 10212 sprays atomized liquid to repeatedly clean the arm part of the hand.

[0062] Furthermore, the drying device 104 includes an air inlet 1041 arranged on the side wall of the first shell 101 and a dryer 1042 arranged in the second frame 202. The dryer 1042 includes a heating plate and an axial fan. When the dryer 1042 is powered on, the axial fan blows out hot air through the heating plate, and the hot air enters the first shell 101 through the air inlet 1041, thereby drying the arms and fingers.

[0063] Furthermore, the detection device 105 includes an infrared detector 1051 and a bacterial detector 1052. Multiple infrared detectors 1051 and bacterial detectors 1052 are provided, one of which is provided corresponding to the finger cleaning device 103, and the remaining infrared detectors 1051 and bacterial detectors 1052 are evenly distributed between the finger cleaning device 103 and the first opening 1011. The infrared detector 1051 is used to detect whether there is a hand, and the bacterial detector 1052 is used to detect the bacterial content of the hand.

[0064] Specifically, at least two infrared detectors 1051 are set, one of which corresponds to the finger cleaning device 103, and the other is set near the first opening 1011. The infrared detector 1051 near the first opening 1011 can detect whether a hand is inserted, and the infrared detector 1051 corresponding to the finger cleaning device 103 can detect whether the finger part is placed in place. When both detect hand information, an electrical signal is given to the control module 30, and the control module 30 receives the start of the cleaning process to control the action of the hand washing module 10.

[0065] The bacterial colony detector 1052 and the infrared detector 1051 are respectively arranged on different sides of the first shell 101 to avoid crowding of multiple parts on one side. Three bacterial colony detectors 1052 can be set, one of which is arranged corresponding to the finger cleaning device 103, and the remaining bacterial colony detectors 1052 are evenly distributed in the side wall space of the first shell 101 between the first opening 1011 and the finger cleaning device 103.

[0066] When cleaning is completed, the bacterial colony detector 1052 is started to perform fluorescence detection on the cleaned arms and fingers, and whether the cleaning meets the standards is determined based on whether the total number of bacterial colonies detected is ≤5 cfu / ml.

[0067] Furthermore, the control module 30 includes a human-computer interaction platform 301 and a control box 302;

[0068] The human-computer interaction platform 301 is set on the top of the first frame 201, and the control box 302 is set in the second frame 202. The control box 302 is communicatively connected with the human-computer interaction platform 301, the supply module 40, the arm washing device 102, the finger washing device 103, the drying device 104 and the detection device 105.

[0069] Specifically, the human-computer interaction platform 301 can be set as a touch screen. The human-computer interaction platform 301 also has a camera that can perform face recognition. When used for the first time, the identity data is entered on the touch screen and the user is recorded through the camera. When used again, the user's facial information can be directly scanned through the camera. After matching the identity information, an electrical signal is provided to the control box 302. The control box 302 controls the lifting module 20 to adjust the hand washing module 10 to a suitable height.

[0070] The control box 302 integrates a switching power supply, a single-chip microcomputer, a voltage stabilizer, a motor drive module, a relay, a voice module and a level conversion module. The single-chip microcomputer receives instructions to control the motor action to complete the hand washing operation. The voice module can give the user corresponding instructions, such as starting cleaning, completing cleaning, etc.

[0071] Furthermore, the supply module 40 is configured as an electro-hydraulic isolation box;

[0072] The electro-hydraulic isolation box is connected to the second through hole 10212 and the finger cleaning device 103 pipeline, and the electro-hydraulic isolation box is used to store hand soap, disinfectant and clean water.

[0073] Specifically, multiple electro-hydraulic isolation boxes can be set up in the second rack 202, which contain diaphragm water pumps and solenoid valves. By installing joints, water sources, air sources and other media are introduced into the box, and then the media are controlled through the joints and solenoid valves to transport water or air to the hand washing module 10 to achieve different hand washing operations such as cleaning, flushing, and disinfection.

[0074] Furthermore, a sewage outlet 1012 is provided at one end of the first shell 101 close to the finger cleaning device 103, and a sewage storage tank 50 is provided in the second frame 202. The sewage outlet 1012 is connected to the sewage storage tank 50 through a pipeline, and the sewage storage tank 50 is connected to the outside of the hand washing robot, so that the sewage after cleaning can be discharged.

[0075] Furthermore, the finger cleaning device 103 includes a fixing plate 1031 and a support frame 1032. The fixing plate 1031 is arranged at the bottom of the first shell 101, and the support frame 1032 is fixed on the fixing plate 1031. There are 5 support frames 1032, and their setting positions correspond to the positions of human fingers. When the user's fingers are placed, all five fingers can be connected to the support frame 1032. The end of the support frame 1032 away from the first opening 1011 has a third through hole 1033. The third through hole 1033 is connected to the electro-hydraulic isolation box pipeline to achieve cleaning of fingers and nails.

[0076] At the same time, an atomizing nozzle is also provided on the third through hole 1033, which can spray atomized liquid to achieve more comprehensive cleaning.

[0077] Further, Figure 4 A flow chart schematically shows a cleaning method of a fully automatic hand washing robot according to an embodiment of the present invention, as shown in FIG. Figure 4 As shown, the present invention also provides a cleaning method applied to the above-mentioned fully automatic hand washing robot, the steps of which include:

[0078] S01: The human-computer interaction platform 301 identifies and matches the identity information, and controls the movement of the lifting module 20 according to the identity information to adjust the use height of the hand washing module 10;

[0079] S02: inserting the hand into the first housing 101, the finger portion corresponds to the finger cleaning device 103, and the cleaning process is started according to the arm portion and finger portion detection information detected by the infrared detector 1051;

[0080] S03: Wash, rinse, dry and disinfect your hands according to the cleaning process;

[0081] S04: Instruct the bacterial colony detector 1052 to perform fluorescence detection on the washed hands, and judge whether the hand washing meets the standard based on the total number of bacterial colonies detected. If so, it will prompt that the hand washing is completed. If not, the washing process will be repeated until the total number of bacterial colonies detected meets the standard.

[0082] Specifically, in step S01, when the user uses the handwashing module for the first time, the user manually enters the identity information on the human-computer interaction platform 301 and records the facial information through the camera. When the user uses the handwashing module again, the camera on the human-computer interaction platform 301 performs facial recognition on the user. After matching the identity information, the lifting module 20 is controlled to adjust the height of the handwashing module 10 according to the content of the identity information.

[0083] The entered identity information may be basic data such as height and weight.

[0084] In step S02, when the hand is inserted into the first shell 101, the infrared detector 1051 monitors in real time whether the hand is placed in place. If it is detected that the hand is placed in place, the infrared detector 1051 sends a first electrical signal. After receiving the signal, the control box 302 starts the cleaning process and controls the hand washing module 10 to operate.

[0085] When the infrared detector 1051 detects that the hand is not in place, it sends out a second electrical signal. After receiving the second electrical signal, the control box 302 controls the built-in voice module to broadcast a message to prompt the user to adjust. After the user adjusts, when it detects that the hand is in place, it controls the hand washing module 10 to operate.

[0086] In step S03, the cleaning process includes four steps of washing, rinsing, drying, and disinfecting the hands. Through the internal control of the electro-hydraulic isolation box, when cleaning is required, hand soap is provided and sprayed from the second through hole 10212 and the third through hole 1033 of the finger cleaning device 103. The movement of the cleaning ring 1021 achieves flushing of the arms and fingers.

[0087] When flushing is required, the electro-hydraulic isolation box provides clean water to flush the arms and fingers;

[0088] When drying is required, the control box 302 controls the drying device 104 to provide hot air, so that the hot air enters the first housing 101 and dries only the arms and fingers. The drying time and temperature can be automatically adjusted and generally last for 30 seconds.

[0089] When disinfection is required, the electro-hydraulic isolation box provides alcohol to flush the arms and fingers to achieve disinfection of the arms and hands.

[0090] In step S04, when cleaning is completed, the flora detector 1052 is started to perform fluorescence detection on the arm and fingers, and the total bacterial colony count on the arm and fingers is detected. The cleaning is judged whether the total bacterial colony count is ≤5cfu / ml to determine whether the cleaning meets the standard. If it meets the standard, the flora detector 1052 provides a third electrical signal. After the control box 302 receives it, the internal voice module prompts that the disinfection is completed. If it does not meet the standard, the above S03 step will be repeated for re-cleaning and disinfection.

[0091] In summary, through the solution of the present invention, a fully automatic hand washing robot is provided, which can automatically wash hands without the need for users to rub them manually, thus freeing the user's hands. At the same time, the hand washing module 10 includes an arm washing device 102 and a finger washing device 103, which can wash the arms and fingers, making the cleaning and disinfection more comprehensive. It also has a detection device 105, which includes an infrared detector 1051, which can detect whether the user's hands are placed in place. When it is detected that they are in place, cleaning will be performed to avoid inadequate cleaning. It also includes a bacterial colony detector 1052, which can detect the total number of bacterial colonies remaining on the hands after washing, to ensure that the hands after washing are disinfected to the standard. The hand washing robot of the present invention can be used in medical, sterile workshops, food and other industries that require hand disinfection and hand hygiene processes.
