Description
Technical Field
[0001] This invention relates to the field of surgical disinfection equipment technology, and more specifically, to a disinfection device for operating room personnel. Background Technology
[0002] Surgical hand disinfection follows the principle of washing hands before disinfection. Before the procedure, remove hand jewelry, trim nails to no more than the fingertips, and clean dirt under the nails. Then, wash hands, forearms, and the lower third of the upper arms with an appropriate amount of detergent, carefully rubbing skin folds and nail crevices. Rinse with running water and dry with a sterile towel from hand to elbow. Disinfection can be done by rinsing or no-rinse method. Apply disinfectant evenly to the above areas and rub properly. For rinsing, rinse thoroughly and dry. For no-rinse method, rub until the disinfectant is dry. Keep hands in front of the chest and above the elbows throughout the procedure. Disinfection is required again in different operating rooms, when gloves are damaged, or when hands are contaminated. After removing gloves, wash hands with soap. Rubbing tools must be disinfected according to regulations or used only once to ensure that the disinfection effect meets hygiene standards.
[0003] In traditional surgical hand disinfection, medical staff need to keep their hands in front of their chest and above their elbows throughout the process to prevent water from flowing backwards on the surface of their arms. However, this process may make it inconvenient to wipe the upper arm area (especially the outer side) and may leave water residue. Therefore, we propose a disinfection device for operating room personnel. Summary of the Invention
[0004] The present invention provides a disinfection device for operating room personnel, which can solve the problem mentioned in the background art that during the hand disinfection process, both hands must be kept in front of the chest and above the elbows to prevent water from flowing backward on the surface of the arms, and this posture makes it inconvenient to wipe the water on the upper arms.
[0005] To achieve the above objectives, this solution provides a disinfection device for operating room personnel, including a mounting frame. A fan and an infrared sensor are mounted on the mounting frame. A motor is installed on the mounting frame, and a drive roller is mounted on the output shaft of the motor.

[0009] Optionally, the mounting bracket is provided with a base for placing a bottle of disinfectant gel, the base being located below the absorbent cloth;
[0010] A disposable film is fitted on the outside of the support plate, and the width of the absorbent cloth exceeds the width of the support plate by 3-5 cm.
[0011] Optionally, the groove includes a horizontal support portion and a sliding inclined portion, the edge of the absorbent cloth is located directly above the pressing part of the disinfectant gel bottle, and after the absorbent cloth slides along the sliding inclined portion, the edge of the absorbent cloth covers the pressing part of the disinfectant gel bottle.
[0012] Optionally, a fixed pressure rod and a fixed shaft are fixedly connected to the surface of the mounting bracket, a rotating pressure rod is installed at the top of the fixed shaft, and a limiting rod is provided on the mounting bracket for contacting the rotating pressure rod.

Detailed Implementation
[0032] To make the aforementioned objectives, features, and advantages of this solution more apparent and understandable, the specific embodiments of this solution are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this solution. However, this solution can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this solution. Therefore, this solution is not limited to the specific embodiments disclosed below.
[0033] In the description of this solution, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this solution and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this solution. The terms "first" and "second" are used to distinguish one element from another and do not have sequential or importance. Furthermore, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings indicate the same or similar elements, which will not be repeated here.
[0034] In this solution, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this solution based on the specific circumstances.
[0035] According to some embodiments of this solution, a disinfection device for operating room personnel is provided, for reference. Figure 1-10 As shown, the operating room personnel disinfection device includes a mounting frame 101, on which a fan 107 and an infrared sensor 102 are mounted. A motor 103 is mounted on the mounting frame 101, and a drive roller 104 is mounted on the output shaft of the motor 103. A rotating shaft is also fixedly connected to the side of the mounting frame 101, and a driven roller 105 is mounted on the rotating shaft. A sterile absorbent cloth 106 is mounted on the driven roller 105, and the other end of the absorbent cloth 106 is wrapped around the drive roller 104. A support plate 108 for supporting the arm is fixedly mounted on the mounting frame 101, and the support plate 108 is located directly below the absorbent cloth 106.
[0036] Thus, when medical staff approach after washing their hands, the infrared sensor 102 detects the medical staff, and the motor 103 and the fan 107 start. The motor 103 drives the drive roller 104 to rotate, converting the used absorbent cloth 106 into an unused absorbent cloth 106. The medical staff then wipe their wet upper arms or elbows on the surface of the clean absorbent cloth 106.
[0037] For details, see Figure 1 and Figure 2 Both the drive roller 104 and the driven roller 105 are equipped with sealing boxes 109 on their outer sides. The two sealing boxes 109 have through grooves 110 on the side near the absorbent cloth 106. The absorbent cloth 106 passes through the through grooves 110. The sealing boxes 109 are fitted with sealing covers on their sides. The sealing boxes 109 and sealing covers isolate the drive roller 104, the driven roller 105, the motor 103 and its transmission components from the external environment, effectively preventing dust, hair, liquid splashes and other pollutants from entering, and avoiding pollutants from being rolled onto the absorbent cloth 106 and causing secondary pollution.
[0038] For details, please refer to Figure 4 , Figure 5 Two mounting slots are provided inside the through groove 110. Each mounting slot is equipped with a clamping sealing plate 111. The two clamping sealing plates 111 are located on both sides of the absorbent cloth 106. A movable spring 112 is connected between the clamping sealing plate 111 and the mounting slot. When the absorbent cloth 106 is stationary, under the continuous pressure of the movable spring 112, the two clamping sealing plates 111 will clamp the stationary absorbent cloth 106, effectively preventing dust, insects, and airborne pollutants from entering the box through the gaps.
[0039] Additionally, please refer to Figure 3Both ends of the support plate 108 are integrally connected with arc-shaped plates 1081 to facilitate the movement of the absorbent cloth 106. The arc-shaped plates 1081 solve the problem of edge scraping of the absorbent cloth 106, allowing the absorbent cloth 106 to move smoothly and reducing wear and resistance. The upper surface of the support plate 108 is provided with a groove 1082 for fitting the upper arm. The part of the groove 1082 that comes into contact with the person is set as a rubber pad. When the medical staff places their arm on the absorbent cloth 106 and the groove 1082 on the support plate 108, the rubber pad groove 1082 automatically adapts to the person's arm. In specific implementation, the groove 1082 can also be set as a rubber airbag with a depression. The rubber airbag can deform and automatically recover to achieve adaptive wrapping of the person's arm.
[0040] In practice, a U-shaped seat is fixedly installed at the bottom of the mounting bracket 101. The mounting bracket 101 can be snapped into place on the sink through the U-shaped seat. Therefore, after washing their hands, medical staff can directly move to the mounting bracket 101 and place their arms on the absorbent cloth 106 to absorb water, preventing water from dripping from their elbows onto the ground. Moreover, the mounting bracket 101 is set as a lifting bracket, which consists of a sleeve and a telescopic rod that is slidably installed in the sleeve. Bolts are provided on the sleeve, and the sleeve and the telescopic rod can be fixed to each other by tightening the bolts. The lifting bracket is a common mechanical structure, and the specific structure of the lifting bracket is well known to those skilled in the art, so it will not be described in detail here.
[0041] Additionally, please refer to Figure 2 The mounting bracket 101 is equipped with a base 201 for placing disinfectant gel bottles. The base 201 is located below the absorbent cloth 106. A disposable film is covered on the outside of the support plate 108. The disposable film can be a disposable polyethylene film, polyvinyl chloride film, etc. When the absorbent cloth 106 is replaced, the disposable film is also replaced. The disposable film isolates contaminants. Disinfection is completed by tearing and replacing it. The width of the absorbent cloth 106 exceeds the width of the support plate 108 by 3-5 cm, forming a hanging cover on both sides to avoid secondary contamination of the support plate 108 when the previous user used it.
[0042] It should be noted that the simplified hand disinfection procedure for medical staff is as follows:
[0043] 1. First, wash your hands, forearms, and lower 1 / 3 of your upper arms with a detergent;
[0044] 2. Use absorbent cloth 106 to absorb water from the upper arm and elbow, and use fan 107 to assist in drying.
[0045] 3. Apply disinfectant gel to hands, forearms, and the lower third of upper arms, and allow to air dry.
[0046] In existing technologies, to avoid direct contact between washed hands and the cap of the disinfectant gel bottle, which could lead to recontamination, mechanical devices (such as airbags) are typically installed on the ground. The gel is dispensed by foot-operated mechanical devices, or by squeezing a pressure plate on top of the bottle with the head, causing the cap to be squeezed and the gel to flow out. However, these methods are not conducive to controlling the amount of gel dispensed. In this device, the cap of the disinfectant gel bottle is positioned below the absorbent cloth 106. After the arms are dry, medical personnel can indirectly apply pressure to the cap of the disinfectant gel bottle by pressing down on the absorbent cloth 106 with their hands. This helps control the amount of gel dispensed and also makes full use of the absorbent cloth 106, preventing waste.
[0047] Specifically, the absorbent cloth 106 covering the pump cap of the hand sanitizer gel bottle only requires a small area; therefore, the pump cap of the hand sanitizer gel bottle can be placed in the dry area of the absorbent cloth 106 (see...). Figure 2 , Figure 3 Directly below the area between the two grooves 1082.
[0048] With the above technical solution, when using the disinfection device for operating room personnel provided by this solution, after medical staff wash their hands, they can directly move to the mounting frame 101, place their arms on the absorbent cloth 106 to absorb water, and avoid water dripping from the elbows onto the ground. When the infrared sensor 102 detects the medical staff, the motor 103 and the fan 107 start. The motor 103 drives the drive roller 104 to rotate, converting the used absorbent cloth 106 into an unused absorbent cloth 106. The medical staff can then place their damp upper arms or elbows on the clean absorbent cloth 106 for targeted wiping, ensuring that the medical staff's arms dry quickly while bent and raised, and preventing water from flowing back onto the skin surface when wiping their arms.
[0049] It should be noted that in the prior art, the signal output terminal of the infrared sensor 102 is electrically connected to the signal input terminal of the DSP controller, and the fan 107 is controlled by the DSP controller. In this embodiment, the motor 103 is also controlled by the DSP controller. When medical personnel approach the infrared sensor 102, the DSP controller sends a start signal to the fan 107 and the motor 103, and the fan 107 and the motor 103 start working.
[0050] In addition, the fan 107 uses a three-stage filtration system consisting of a pre-filter, a medium-efficiency filter, and a HEPA high-efficiency filter to intercept 0.3μm particles and microorganisms. It also uses ultraviolet light and photocatalytic sterilization modules to inactivate residual bacteria. Low-humidity and hot air is used to inhibit bacterial growth. Regular testing and maintenance ensure that the output air meets sterility standards. The specific structure and principles involved in the sterile air delivered by the fan 107 are well known to those skilled in the art and will not be elaborated here.
[0051] In some implementations of this solution, reference is made to Figure 2 , Figure 3 and Figure 8 As shown, the groove 1082 includes a horizontal support portion 10821 and a sliding inclined portion 10822. The edge of the absorbent cloth 106 is located directly above the pressing part of the disinfectant gel bottle, and after the absorbent cloth 106 slides along the sliding inclined portion 10822, the edge of the absorbent cloth 106 covers the pressing part of the disinfectant gel bottle.
[0052] It should be noted that the base 201 is located at the edge of the absorbent cloth 106, and the top of the disinfectant gel bottle is located directly below the edge of the absorbent cloth 106. This is to prevent medical staff from accidentally touching the top of the gel when pressing their arm down on the absorbent cloth 106, causing the gel to be squeezed out prematurely and wasted. At the same time, it also prevents the absorbent cloth 106 from obstructing the user's view of the press cap. In addition, if the absorbent cloth 106 is not wide enough, the edge of the absorbent cloth 106 will not be able to cover the cap of the disinfectant gel bottle. If the absorbent cloth 106 is too wide, it will also be wasted. Therefore, the groove 1082 includes a horizontal support part 10821 and a sliding inclined part 10822. After the medical staff puts their arm into the groove 1082, the absorbent cloth 106 slides along the sliding inclined part 10822, so that the edge of the absorbent cloth 106 slides toward the disinfectant gel bottle, making the side of the absorbent cloth 106 near the disinfectant gel bottle loose enough to ensure that the edge of the absorbent cloth 106 completely covers the pressing part of the disinfectant gel bottle.
[0053] Additionally, please refer to Figure 2 The mounting frame 101 is fixedly connected to a fixed pressure rod 301 and a fixed shaft 302. A rotating pressure rod 303 is installed at the top of the fixed shaft 302. A limiting rod 304 is provided on the mounting frame 101 to abut against the rotating pressure rod 303. Both the fixed pressure rod 301 and the rotating pressure rod 303 are located above the absorbent cloth 106. Specifically, the top of the fixed shaft 302 is dampedly connected to the rotating pressure rod 303 (the top of the fixed shaft 302 is connected to one end of the damping shaft, and one end of the rotating pressure rod 303 is connected to the other end of the damping shaft. The damping shaft generates constant resistance by relying on internal damping medium or friction structure to offset external force, realize arbitrary angle suspension, slow opening and closing, stable support and no rebound).
[0054] The static friction between the rotating pressure rod 303 and the absorbent cloth 106 below is significantly greater than the rotational resistance of the fixed shaft 302. As the medical staff dries their arms, the absorbent cloth 106 changes from a taut to a relaxed state. The rotating pressure rod 303 and the absorbent cloth 106 are thus shifted to the left. When the motor 103 rotates... Figure 8The drive roller 104 starts to rotate. The drive roller 104 overcomes the damping of the fixed shaft 302, thereby driving the rotating pressure rod 303 to rotate as a whole. This tightens and straightens the absorbent cloth 106 on the left side of the pressure rod, which was originally loose or wrinkled, so that it enters a tensioned state. Then the drive roller 104 continues to rotate and passes through the tensioned cloth surface, starting to smoothly pull the entire absorbent cloth 106 to move.
[0055] The motor 103 has a spiral spring 401 sleeved on its output shaft. The drive roller 104 has an installation groove inside. The other end of the spiral spring 401 is connected to the inner wall of the installation groove. The output shaft of the motor 103 is rotatably connected to the drive roller 104. When the motor 103 starts, the spiral spring 401 deforms and the drive roller 104 rotates slowly to prevent the drive roller 104 from suddenly stretching the absorbent cloth 106 at the moment the motor 103 starts, causing the absorbent cloth 106 to become entangled and misaligned.
[0056] In some embodiments, reference Figure 6 As shown, a number of spring plates 305 are fixedly connected to the bottom of the rotating pressure rod 303. A pressure plate 306 is provided at the other end of the spring plate 305. The spring plate 305 provides abutment and pressing for the pressure plate 306, so that the pressure plate 306 can always press the absorbent cloth 106 flatly on the working surface.
[0057] In other embodiments, reference is made to Figure 9 As shown, several sliders 501 are slidably mounted on the rotating pressure rod 303. Bolts 502 are threaded onto the sliders 501. A compression spring 503 is provided at the bottom end of the bolt 502. A pressure block 504 is fixedly connected to the other end of the compression spring 503. The pressure block 504 abuts against the surface of the absorbent cloth 106. The bolts 502 and sliders 501 can adjust the degree and position of the pressure block 504 on the absorbent cloth 106 to prevent the absorbent cloth 106 from shifting due to dragging.
[0058] In practice, the rotational resistance of the drive roller 104 is adjusted by adjusting the ratio of the outer diameter of the drive roller 104 to the diameter of the output shaft of the motor 103. According to the lever principle, the larger the ratio of the outer diameter of the drive roller 104 to the diameter of the output shaft of the motor 103, the easier it is for the drive roller 104 to rotate. In addition, the motor 103 can also be set as a stepper motor. Before the motor 103 stops, it is reversed by a certain angle to make the absorbent cloth 106 on the drive roller 104 in a relaxed state.
[0059] It should be noted that after the medical staff puts their arm into the groove 1082, the absorbent cloth 106 slides along the sliding inclined part 10822, so that the edge of the absorbent cloth 106 slides towards the disinfectant gel bottle, making the side of the absorbent cloth 106 close to the disinfectant gel bottle loose enough to ensure that the edge of the absorbent cloth 106 completely covers the pressing part of the disinfectant gel bottle. At this time, the absorbent cloth 106 is in a wrinkled state. If the drive roller 104 directly takes in the absorbent cloth 106, it will cause the absorbent cloth 106 to be misaligned. Therefore, when the drive roller 104 rotates, the drive roller 104 first overcomes the damping of the fixed shaft 302, rotates the pressure rod 303 and moves the absorbent cloth 106 as a whole, tightens and straightens the absorbent cloth 106 that was originally loose or wrinkled on the left side of the rotating pressure rod 303, so that it enters a tensioned state. Then the drive roller 104 continues to rotate through the tensioned cloth surface and begins to smoothly pull the entire absorbent cloth 106 to move.
[0060] The preferred embodiments of this solution have been described in detail above with reference to the accompanying drawings. However, this solution is not limited to the specific details in the above embodiments. Within the scope of the technical concept of this solution, various simple modifications can be made to the technical solution, and these simple modifications all fall within the protection scope of this solution.
[0061] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this solution will not describe the various possible combinations separately.
[0062] Furthermore, various implementations of this solution can be combined in any way, as long as they do not violate the spirit of this solution, they should also be regarded as the content disclosed in this solution.
