Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical disinfection, in particular to a surgical hand disinfection device with self-cleaning function. BACKGROUND

[0002] The scientific setting of the medical hand disinfection device is one of the core measures of hospital infection control, which needs to be combined with position rationality, equipment safety, operation convenience and maintenance standardization to ensure its effective role in actual work, facilitate fast and convenient hand disinfection, reduce the transmission of pathogens between medical staff and patients, especially contact transmission (such as drug-resistant bacteria, viruses, fungi, etc.), and is suitable for scenes where standard hand washing cannot be immediately performed (such as before and after emergency operation, after ward round, etc.), so as to ultimately reduce the risk of nosocomial infection and protect the safety of patients and medical staff.

[0003] The currently recommended patient hand disinfection device is a non-contact hand disinfection device, which is generally an inductive sprayer or an automatic dispenser. The inductive sprayer triggers the spraying of disinfectant by infrared / capacitive induction, and the automatic dispenser triggers the spraying of disinfectant by pressing, foot stepping or induction, which can avoid cross contamination caused by hand contact with the pressing part.

[0004] When the inductive sprayer or automatic dispenser triggers the spraying of disinfectant, the disinfectant is sprayed on the hands to complete hand disinfection by rubbing. However, during rubbing, the disinfectant sprayed on the hands can cause some splashed disinfectant to adhere to the bacteria, dust and other substances originally adhered to the hands to adhere to the shell wall around the disinfection device spraying area. The disinfectant is usually a complex formula with quick-acting and long-lasting bacteriostatic functions. When a single disinfection device is used frequently, the disinfection device may not be cleaned in time within a short period of time, and then crystallization may be formed on the shell wall around the disinfection device spraying area. The liquid disinfectant before crystallization can also further adhere to the dust in the air, causing a thick layer of dirt to form on the inner wall of the disinfection device spraying area, thereby affecting the hand disinfection effect.

[0005] Meanwhile, during the hand preparation before surgical operation, especially for high-risk or deep tissue surgery, the patient also needs to achieve a sterile disinfection state, so the patient's hands and other areas also need to be disinfected. At present, when disinfecting the patient's hands, iodophor gauze is usually used for wiping disinfection. Some patients' hands are prone to be in a state of weakness, and manual wiping is laborious and incomplete, which can easily lead to incomplete disinfection and low disinfection efficiency. SUMMARY

[0006] In view of the deficiencies in the prior art, the hand sterilizer with self-cleaning function for surgery is provided to solve the problem that the disinfectant crystals and dust and dirt residues are easily formed on the inner wall of the sterilizer after use, thereby affecting the disinfection effect of the hand.

[0046] In addition, as shown in the figure, Figure 1 As shown, the top surface of the disinfection spraying cavity 101 of the shell 10 is provided with a plurality of linearly arranged lamp strips 108, the number of the lamp strips 108 is 5, and the 5 groups of lamp strips 108 are located between the adjacent two spray heads 201, and there is only one group of lamp strips 108 between the adjacent two spray heads 201, the lamp strips 108 are located at the middle part of the two spray heads 201, and the axis of the lamp strips 108 is parallel to the axis of the first rotating shaft 301; the lamp strips 108 are electrically connected with a fifth controller for controlling the start or stop of the lamp strips 108, the fifth controller is electrically connected with the PLC processor, and the lamp strips 108 and the fifth controller are electrically connected with the battery; the power output end of the battery is electrically connected with a power management module for supplying power to the first camera 204, the first image processing module, the second camera 203, the second image processing module, the first controller, the second controller, the third controller, the fourth controller, the PLC processor, the first motor, the second motor, the liquid pump, the spray head 201, the electronic switch valve, the fifth controller and the lamp strips 108, and the power management module includes an ACDC module and a plurality of DCDC modules.

[0047] In this embodiment, before using the surgical hand disinfection device with self-cleaning function, the film roll is installed on the first rotating shaft 301 on the left side, and then the free end of the film is laid along the left vertical surface, the lower surface and the right vertical surface of the disinfection spraying cavity 101, the free end of the film passes through the first groove 102, the first communication groove 104 and the second communication groove 105 and enters the second groove 103, the free end of the film is fixed to the second rotating shaft 302, and the side edge of the film is embedded in the embedding groove 106, the embedding groove 106 can limit the laying of the film, so that the film is stably attached to the left vertical surface, the lower surface and the right vertical surface of the disinfection spraying cavity 101, and the inner wall of the disinfection spraying cavity 101 is cleaned and protected.

[0048] During use, after the patient passes through the curved frame 11 and extends into the disinfection spray chamber 101, the second camera 203 obtains image information and transmits it to the second image processing module. The second image processing module determines the number of hands entering and the approximate angle of the hands. At the same time, the first camera 204 obtains image information of the position of the human hand in the disinfection spray chamber 101 and transmits it to the first image processing module. The first image processing module further specifically determines the number of hands entering and the specific angle of the hands. The PLC processor combines the data information of the first image processing module and the second image processing module to further comprehensively determine the position and number of human hands. At this time, the PLC processor controls the nozzle 201 at the corresponding position to start through the fourth controller. At the same time, the PLC processor controls the electronic switch valve on the corresponding infusion tube to start, and synchronously controls the liquid pump to start through the third controller, so that the disinfectant is pumped into the corresponding opened infusion tube through the liquid pump and then discharged from the corresponding nozzle. 201 is sprayed, so as to realize more refined disinfectant spraying on the hands; when only one hand enters or the hand is small, the spraying amount of disinfectant can be reduced, thereby reducing the waste of disinfectant and realizing precise spraying; when the PLC processor obtains the digital information of the second image processing module, the PLC processor controls the light strip 108 to turn on through the fifth controller, and the light strip 108 reflects light to form a light column under the action of the spray formed by the disinfectant. The light emitted by the light strip 108 can more accurately indicate the distribution position of the fingers, which is convenient for spraying the disinfectant. The nozzle 201 can be opposite to the gaps between the fingers, which is convenient for more precise atomization spraying of disinfectant at the gaps between the fingers. Then, when two hands are inserted into the disinfection spray chamber 101 at the same time, it is also more convenient to indicate the distribution position of the two hands after insertion, which is convenient for uniform disinfection; at the same time, under the support of the arc frame 11, the patient is not likely to touch the inner wall of the disinfection spray chamber 101, making the disinfection of the patient's hands more labor-saving and easier to disinfect more comprehensively.

[0049] After the disinfection is completed, the human hand is removed from the disinfection spray chamber 101 and the arc frame 11. After the first camera 204 and the second camera 203 obtain image information, the first image processing module and the second image processing module can quickly transmit the information to the PLC processor. The PLC processor controls the nozzle 201 to be closed through the fourth controller, the third controller to control the liquid pump to be closed, and at the same time the fifth controller controls the light strip 108 to be closed, and the opened electronic switch valve is also controlled to be closed synchronously.

[0050] The first camera 204 continuously collects image information of the film on the bottom surface and side surface of the disinfection spraying cavity 101. When the first image processing module learns that the film is dirty, the first image processing module transmits information about the film to be replaced to the PLC processor. The PLC processor controls the first motor to start and drive the first rotating shaft 301 to unwind the film roll. At the same time, the PLC processor controls the second motor to start and drive the second rotating shaft 302 to wind the film roll. In this way, the film on the left vertical surface, the lower surface, and the right vertical surface of the disinfection spraying cavity 101 is replaced. The film can be wound on the second rotating shaft 302, and the dirt on the film will not scatter everywhere. At the same time, the left vertical surface, the lower surface, and the right vertical surface of the disinfection spraying cavity 101 remain relatively clean, and the disinfection environment is better.

[0051] When the disinfectant in the liquid adding box 40 is sprayed out, the hand is attached to the recess 401, and the entire liquid adding box 40 is pulled out horizontally. The liquid adding head 501 at the right end of the liquid adding box 40 is unscrewed, disinfectant is added to the liquid adding box 40, and the liquid adding head 501 is screwed onto the liquid adding box 40. During this process, the tension spring 504 is in a contracted state, and the left side of the plug 503 in the liquid adding head 501 is in a sealing state with the stepped structure of the liquid adding head 501. The disinfectant will not leak. At the same time, during the process of adding liquid and transferring the liquid adding box 40, the one-way air inlet pressure relief valve 402 on the upper right side is not easy to contact with the disinfectant and will not leak.

[0052] When the liquid adding box 40 containing disinfectant is installed again in the liquid adding cavity 107 of the shell 10, the liquid adding box 40 is pushed horizontally into the liquid adding cavity 107. As shown in Figure 3 , the access pipe 60 can first contact and abut against the limiting communication groove 505 at the right end of the plug 503. When it continues to move to the right, the access pipe 60 pushes the entire plug 503 to move to the left relative to the liquid adding box 40, and the sealing ring 507 on the outer wall of the liquid adding head 501 is embedded into the limiting groove, thereby fixing and limiting the outer wall of the plug 503. As shown in Figure 4 , after the access pipe 60 pushes the plug 503 to move to the left, the tension spring 504 is stretched. When the left end of the plug 503 is separated from the stepped structure on the inner wall of the liquid adding head 501 to form a liquid outlet gap 70, the liquid outlet gap 70, the flow guide groove 506, the limiting communication groove 505, and the access pipe 60 are sequentially communicated, which facilitates the disinfectant to enter the access pipe 60. At this time, as shown in Figure 4 , the right end of the plug 503 continuously abuts against the inner wall of the liquid outlet hole 502 to prevent liquid leakage.

[0053] When the entire hand sanitizer is installed and maintained, it can be quickly disassembled and maintained through the hanging buckle installation assembly, and the internal structures in the shell 10 can be easily maintained by disassembling the back plate 801.

The support column 902 is vertically and fixedly installed on the top side of the walking robot 901, and the upper end of the support column 902 is fixedly connected to the bottom of the shell 10 by screws. The power supply batteries are installed in the support column 902 and are electrically connected to the walking robot 901. The top end of the support column 902 is provided with a first plug-in interface electrically connected to the power supply batteries. The lower surface of the shell 10 is provided with a second plug-in interface 110 that can be plugged into and electrically connected to the first plug-in interface.
