[0002] Surgical hand disinfection refers to the process in which medical staff use running water and hand soap to rub and rinse their hands, forearms to the lower 1 / 3 of the upper arm, and then use hand disinfectant to remove or eliminate temporary bacteria on the hands and forearms to the lower 1 / 3 of the upper arm and reduce permanent bacteria. Traditional preoperative hand washing and disinfection uses the seven-step hand washing method for manual cleaning. This process has strict requirements on the hand washing posture of medical staff. If the hand washing posture is not standardized or the hand washing time is not up to standard, the surgical process may be contaminated.

[0003] The existing surgical hand washing equipment includes a cleaning liquid spraying chamber and a scrubbing chamber. The medical staff first puts their hands into the cleaning liquid spraying chamber, sprays the cleaning liquid on their hands, and then takes their hands out and puts them into the scrubbing chamber to rinse the cleaning liquid on their hands with water. This cleaning method has the following problems:

[0004] 1) It is necessary to spray the cleaning liquid and rinse the hands in two chambers respectively, and the actions required by medical staff are relatively complicated;

[0005] 2) When the hands are moved from the cleaning liquid spraying chamber to the washing chamber, there may be other factors that affect the disinfection effect, and some cleaning liquid may drip and wet the ground, which may easily cause medical staff to fall or get hurt;

[0006] 3) Only the hands can be cleaned, and the forearm to the lower 1 / 3 of the upper arm cannot be cleaned.

[0007] Therefore, how to design an operating room hand scrubbing device that can clean the hands, forearms to the lower 1 / 3 of the upper arm, so that during the cleaning process, the hands, forearms to the lower 1 / 3 of the upper arm do not need to be transferred from one chamber to another, to avoid the ground being wetted by water and cleaning fluid, causing medical staff to fall, bump, and other accidents, and to reduce the complexity of the operation is a technical problem that technical personnel in this field urgently need to solve.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] like Figures 1 to 11As shown, the present invention provides an operating room hand scrubbing device, comprising a housing 1, the housing 1 having a cleaning cavity 4 for accommodating a hand, a forearm to the lower 1 / 3 of an upper arm, the cleaning cavity 4 extending along the width direction of the housing 1 and not penetrating one of the front and rear surfaces of the housing 1, the cleaning cavity 4 being arranged in pairs and having an opening for a hand and an arm to enter and exit;

[0042] The housing 1 is provided with a flushing nozzle 11 capable of spraying water into the cleaning chamber 4, a cleaning liquid nozzle 14 capable of spraying cleaning liquid into the cleaning chamber 4, a first driving mechanism capable of driving the flushing nozzle 11 to move linearly, and a second driving mechanism capable of driving the cleaning liquid nozzle 14 to move linearly. The flushing nozzle 11 and the cleaning liquid nozzle 14 move alternately, that is, the flushing nozzle 11 and the cleaning liquid nozzle 14 do not move synchronously, but one moves after the other moves; the water outlet direction of the flushing nozzle 11 and the liquid outlet direction of the cleaning liquid nozzle 14 are both toward the cleaning chamber 4, and the movement path of the flushing nozzle 11 is consistent with that of the cleaning liquid nozzle 14. The movement paths of the nozzles 14 are independent of each other, and the projection of the movement path of the flushing nozzle 11 in the length direction of the cleaning chamber 4 overlaps with the projection of the movement path of the cleaning liquid nozzle 14 in the length direction of the cleaning chamber 4, and the length of the overlapping area is not less than the maximum length from the hand and forearm to the lower 1 / 3 of the upper arm, and the projection length of the movement path of the flushing nozzle 11 in the length direction of the cleaning chamber 4 is not shorter than the projection length of the movement path of the cleaning liquid nozzle 14 in the length direction of the cleaning chamber 4, so as to complete the actions of wetting the hands and arms of medical staff, spraying cleaning liquid and flushing cleaning liquid, thereby achieving cleaning of the hands and arms.

[0043] If the flushing nozzle 11 and the cleaning liquid nozzle 14 are long strip joints extending along the length direction of the cleaning chamber 4, it is necessary to evenly arrange a plurality of flushing nozzles 11 and cleaning liquid nozzles 14 along the circumference of the cleaning chamber 4, so that the flushing nozzles 11 and the cleaning liquid nozzles 14 can perform all-round cleaning and disinfection on the hands and arms without leaving any dead corners. In one embodiment, the flushing nozzle 11 and the cleaning liquid nozzle 14 are both annular structures, and at least four water nozzles 17 are evenly distributed along the circumference of the flushing nozzle 11, and at least four liquid nozzles 13 are evenly distributed along the circumference of the cleaning liquid nozzle 14. In addition, in the cross section of the cleaning chamber 4, the flushing nozzle 11 and the cleaning liquid nozzle 14 are sequentially distributed from the inside to the outside, ensuring that the flushing nozzle 11 will not interfere with the cleaning liquid nozzle 14 when it moves, and the corresponding cleaning liquid nozzle 14 will not interfere with the flushing nozzle 11 when it moves. The number of water spray nozzles 17 and the number of liquid spray nozzles 13 can be four, five, six, seven or more. However, no matter how many are provided, the water sprayed by all water spray nozzles 17 and the cleaning liquid sprayed by all liquid spray nozzles 13 should be able to completely cover the entire periphery of the hand and arm. In one embodiment, seven water spray nozzles 17 are provided on the flushing nozzle 11, and seven liquid spray nozzles 13 are provided on the cleaning liquid nozzle 14.

[0044] In one embodiment, the flushing nozzle 11 is a first annular structure that is sleeved on the outside of the cleaning chamber 4. A temporary water storage chamber 19 connected to a water source is provided between the inner and outer surfaces of the first annular structure. The temporary water storage chamber 19 is also an annular structure. A water nozzle 17 connected to the temporary water storage chamber 19 is provided on the first annular structure, and the first annular structure is transmission-connected to the first driving mechanism.

[0045] In order to increase the wetting and flushing speed, two flushing nozzles 11 that can move toward each other are provided along the length direction of the cleaning chamber 4. Fig.10 and Fig.11 In one embodiment, the water nozzle 17 is located on the end faces of the two flushing nozzles 11 facing each other, and the axis of the water nozzle 17 is inclined relative to the length direction of the cleaning chamber 4. The water outlet direction of the water nozzles 17 on the two flushing nozzles 11 is toward the other flushing nozzle 11, and the water nozzles 17 located on the upper and lower sides of the same flushing nozzle 11 are inclined toward the direction close to the central axis, so that the sprayed water flow is conical, so as to achieve the best flushing effect and the largest flushing range, and avoid the generation of cleaning dead corners. In addition, compared with the vertically sprayed water flow, the inclined sprayed water flow has a smaller impact force on the skin, which can reduce the damage to the skin. The liquid spray nozzle 13 is located on the side of the cleaning liquid nozzle 14 facing the cleaning chamber, and the cleaning liquid sprayed by the liquid spray nozzle 13 is also conical.

[0046] In one embodiment, the cleaning liquid spray head 14 is a second annular structure sleeved on the outside of the flushing nozzle 11, and a temporary liquid storage cavity 12 connected to the cleaning liquid source is provided between the inner and outer surfaces of the second annular structure, and a liquid spray nozzle 13 connected to the temporary liquid storage cavity 12 is provided on the second annular structure, and the second annular structure is in transmission connection with the second driving mechanism. In order to prevent the water pipe 21 used to connect the temporary water storage cavity 19 with the water source and / or the liquid infusion pipe 20 used to connect the temporary liquid storage cavity 12 with the cleaning liquid source from being entangled with each other when the flushing nozzle 11 moves, a first channel for storing the water pipe 21 and a second channel for storing the liquid infusion pipe 20 are provided in the housing 1, and the first channel and the first channel, the second channel and the second channel, and the first channel and the second channel are not connected to each other. The water pipe 21 and the liquid infusion pipe 20 are both deformable hoses. In one embodiment, the water pipe 21 and the liquid infusion pipe 20 are both spiral hoses.

[0047] The first drive mechanism and the second drive mechanism both include a fixed motor and a screw rod fixedly connected to the output shaft of the motor, the axis of the screw rod is parallel to the length direction of the cleaning chamber 4, the flushing nozzle 11 is provided with a first connecting ring 18, the cleaning liquid nozzle 14 is provided with a second connecting ring 9, the first connecting ring 18 is fixedly connected to the flushing nozzle 11, the second connecting ring 9 is fixedly connected to the cleaning liquid nozzle 14, the first connecting ring 18 is sleeved on the screw rod of the first drive mechanism and is threadedly connected to the screw rod, and the second connecting ring 9 is sleeved on the screw rod of the second drive mechanism and is threadedly connected to the screw rod. The motor drives the screw rod to rotate, so that the first connecting ring 18 drives the flushing nozzle 11 to move linearly along the screw rod, and the second connecting ring 9 drives the cleaning liquid nozzle 14 to move linearly along the screw rod. In one embodiment, the screw rod used in conjunction with the first connecting ring 18 is a double-threaded screw rod.

[0048] In order to protect the hands and arms to be washed from contacting the rotating screw and improve the safety of the hand washing device, a protective cover 16 with a soft surface is provided on the inner wall of the washing chamber 4, and a first hole groove 22 and a second hole groove 23 are provided on the protective cover 16. One end of the first hole groove 22 is connected to the washing chamber 4, and the other end is connected to the flushing nozzle 11. One end of the second hole groove 23 is connected to the washing chamber 4, and the other end is connected to the cleaning liquid nozzle 14. The water sprayed from the water nozzle 17 is injected into the washing chamber 4 through the first hole groove 22, and the cleaning liquid sprayed from the liquid nozzle 13 is injected into the washing chamber 4 through the second hole groove 23. Since the flushing nozzle 11 and the cleaning liquid nozzle 14 are respectively located at different radial positions of the washing chamber 4, the cleaning liquid nozzle 14 and the flushing nozzle 11 are alternately operated and the movement path of the cleaning liquid nozzle 14 is shorter than the movement path of the flushing nozzle 11, so the first hole groove 22 and the second hole groove 23 can also be combined into one. To improve the cleaning effect, in one embodiment, the pressure of the water flow sprayed from the water spray nozzle 17 ranges from 0.4 MPa to 0.6 MPa.

[0049] For the sake of a clearer description, the motor connected to the flushing nozzle 11 is called the first motor 15, the motor connected to the cleaning liquid nozzle 14 is called the second motor 6, the screw connected to the first motor 15 is called the first screw 10, and the screw connected to the second motor 6 is called the second screw 8. An electrical installation room is provided on the housing 1, and the first motor 15 and the second motor 6 are both installed in the electrical installation room. A mounting hole is provided along the radial outside of the cleaning cavity 4, the first screw 10 is installed on the inner wall of the mounting hole through the bearing 7, and the second screw 8 is installed on the outer wall of the mounting hole through the bearing 7. The outer wall of the mounting hole can be a protective sleeve 16 or a structure different from the protective sleeve 16. If it is a structure other than the protective sleeve 16, a through hole is also required to be provided at the position corresponding to the first hole slot 22 and the second hole slot 23 on the mounting hole. The present invention is provided with a hot air blower 28 for blowing hot air into the cleaning cavity 4 at one end away from the opening. In one embodiment, the hot air blower 28 is also installed in the electrical installation room and is placed in the area between the first motor 15 and the second motor 6.

[0050] In order to cover medical staff of different heights, at least two groups of cleaning chambers 4 are provided on the housing 1, and the two groups of cleaning chambers 4 are arranged sequentially in the height direction.

[0051] In order to improve the automatic performance of the hand washing device, an infrared sensor 5 is provided between the paired cleaning chambers 4, a flushing switch valve is provided on the pipeline for connecting the flushing nozzle 11 and the water source, and a liquid spraying switch valve is provided on the pipeline for connecting the cleaning liquid nozzle 14 and the cleaning liquid source. The infrared sensor 5, the flushing switch valve, the liquid spraying switch valve, the first motor 15, the second motor 6 and the hot air blower 28 are all connected to the control component signal. In one embodiment, a countdown display 3 and a display screen 2 are provided on the housing 1, each countdown display 3 corresponds to a group of cleaning chambers 4, and the countdown display 3 is connected to the control component signal, and the current status information of the hand washing device, such as water pressure, flow rate, etc., is displayed on the display screen 2. The housing 1 is also provided with a power switch 24 connected to the electrical equipment, a water inlet 25 connected to the water delivery pipe 21, a water outlet 26 and a liquid inlet 27 connected to the liquid delivery pipe 20, and a wastewater storage chamber for storing dirty water is provided at the bottom of the housing 1, and the wastewater storage chamber is connected to the water outlet 26.

[0052] When in use, the medical staff selects a washing chamber 4 of a suitable height according to their own height, and puts their hands into the washing chamber 4. After the infrared sensor 5 senses the staff, the hand washing device starts to work, the flushing switch valve is opened, the first motor 15 is started, one flushing nozzle 11 moves from the hand to the arm, and the other flushing nozzle 11 moves from the arm to the hand. The two flushing nozzles 11 meet in the middle of the arm, and then the first motor 15 is reversed, and the two flushing nozzles 11 return to their original positions respectively, and the first motor 15 and the flushing switch valve are closed. Then the second motor 6 is started, the spray switch valve is opened, and the hand sanitizer nozzle moves from the hand to the arm or from the arm to the hand to spray the cleaning liquid on the hand and arm, wherein the sprayed cleaning liquid is in a mist state. After the cleaning liquid is sprayed, the cleaning liquid nozzle 14 returns to its original position, and the second motor 6 and the spray switch valve are closed. Then, the first motor 15 is started again, and the flushing switch valve is opened again to rinse off the cleaning liquid on the hands and arms. After rinsing, the first motor 15 and the flushing switch valve are closed, and the hot air blower 28 is started to dry the washed parts. After the hand washing device starts working, the countdown display 3 counts down. After the countdown is completed, the staff can withdraw their hands and leave to proceed to the next disinfection process. After everyone has completed the cleaning and disinfection work, the water outlet 26 is opened to discharge the dirty water in the wastewater storage chamber, and the power switch 24 is turned off.
