Technical Field
[0001] This invention belongs to the field of aseptic work technology, specifically relating to a single-person aseptic gown donning and doffing aid device and method. Background Technology
[0002] Sterile gowns are widely used in medical surgeries, laboratory aseptic operations, biological product preparation, and other work scenarios with high requirements for cleanliness and isolation. Their main function is to isolate the operator's body from the external sterile environment, reducing the risk of contamination of the sterile area by personnel activity. In practice, sterile gowns typically need to be put on before entering the sterile work area and removed according to regulations after the work is completed to ensure that the entire process complies with aseptic operating procedures.
[0003] Currently, the donning and doffing of sterile gowns largely relies on medical staff, laboratory personnel, or other operational staff to complete the process independently, or with the assistance of support staff. In scenarios requiring a single person to perform the donning and doffing procedures independently, the operator not only needs to support, unfold, and position the sterile gown, but also needs to minimize undue contact between their hands, the outer surface of the gown, and non-sterile areas during the process to reduce the risk of contamination. Therefore, under single-person use conditions, the donning and doffing of sterile gowns places higher demands on support conditions and operational coordination.
[0004] However, in the existing technology, there is usually a lack of systematic auxiliary means that can simultaneously adapt to different user body shapes and provide stable support, positioning and assisted removal of sterile gowns during the process of donning and doffing sterile gowns for single use. This results in poor coordination when a single person is donning and doffing sterile gowns, the process is not smooth enough, and it is not conducive to reducing the risk of contamination caused by inconvenient operation. Summary of the Invention
[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a single-person sterile gown donning and doffing assistance device and method, which can solve the above problems.
[0006] To achieve the above objectives, the present invention provides the following technical solution: A single-person sterile gown donning and doffing auxiliary device includes an L-shaped base plate, a screw for driving a lifting seat to rise and fall on the L-shaped base plate, a support hanger for mounting the sterile gown on the lifting seat, and telescopic plates that can move laterally on both sides of the lifting seat. The telescopic plates are provided with arc-shaped cuff support plates for supporting the cuffs of the sterile gown. The lifting platform is also equipped with an adjusting block and a first connecting rod for driving the two telescopic plates to move closer or further apart; The telescopic plate is provided with a pressure block for pressing and fixing the sleeve fitted on the arc-shaped cuff support plate. The pressure block is connected to the control ring through a second linkage. A spring is provided between the pressure block and the telescopic plate for pressing the pressure block down to reset it.
[0007] Furthermore, side guardrails are provided on both sides of the L-shaped base plate, and uprights are symmetrically fixed on the back side of the L-shaped base plate. A top plate is fixed on the top of the two uprights. The lead screw is horizontally rotatably installed between the L-shaped base plate and the top plate, and the lead screw is located between the two uprights. A rotating handle is provided on the top of the lead screw. The lifting seat is slidably installed on the two uprights and screwed onto the surface of the lead screw.
[0008] Furthermore, a front extension beam is provided above the front surface of the lifting seat, and the supporting clothes rack is fixed to the front end of the front extension beam; side extension beams are provided on both sides of the lifting seat, and T-shaped sliding grooves are provided on the side extension beams. The front side and the end of the T-shaped sliding grooves are both in an open state, and the telescopic plate is slidably installed on the inner side of the side extension beams, and the telescopic plate extends out of the end face of the side extension beams.
[0009] Furthermore, a screw is rotatably mounted at the center below the surface of the lifting seat, the adjusting block is screwed onto the surface of the screw, and first connecting rods are symmetrically hinged on both sides of the adjusting block. The ends of the two first connecting rods opposite to the adjusting block are respectively hinged to two telescopic plates.
[0010] Furthermore, each of the two telescopic plates has a fixing ring at one end facing away from each other, and an arc-shaped cuff support plate is provided on the front side of the fixing ring. The arc-shaped cuff support plate is used to support the cuff.
[0011] Furthermore, the telescopic plate has an installation groove at its end, which is located above the center of the fixing ring. The pressure block is vertically slidably installed in the installation groove, and a rubber pressure plate is provided at the front end of the pressure block. The rubber pressure plate is located above the root of the arc-shaped cuff support plate.
[0012] Furthermore, a fixing bolt is fixed to the upper surface of the pressure block, the fixing bolt penetrates the upper surface of the telescopic plate, and the spring is sleeved on the surface of the fixing bolt and located inside the mounting groove.
[0013] Furthermore, the control ring is rotatably mounted on the rear side of the fixed ring, a rod is fixed on the inner side of the control ring, an eccentric bolt is provided on the rear surface of the control ring, one end of the second connecting rod is rotatably mounted on the surface of the eccentric bolt, and the other end of the second connecting rod is hinged to the back of the pressure block.
[0014] A method for assisting in the donning and doffing of sterile gowns using a single-person sterile gown donning and doffing aid device, characterized by comprising the following steps: S1. Rotate the lead screw to make the lifting seat slide along the surface of the column to adjust the height of the clothes hanger and the telescopic plate. S2. Rotate the screw, and through the cooperation of the adjusting block and the first connecting rod, drive the two telescopic plates to move laterally to adjust the distance between the two arc-shaped cuff support plates; S3. Place the sterile garment hanger on the support hanger and put the sterile garment cuffs on the curved cuff support plate. S4. The second linkage is driven by the control ring to control the lifting or lowering of the pressure block, thereby releasing or squeezing the rubber pressure plate to fix the cuff.
[0015] Furthermore, when removing the garment, raise both arms and extend them forward along the inside of the curved cuff support plate. After the arms have reached the predetermined length, the control ring is rotated by the lever, causing the eccentric bolt to move the pressure block upward via the second connecting rod, thus raising the rubber pressure plate. Continue to extend forward until the cuff is below the rubber pressure plate, then release the control ring. Under the action of the spring, the pressure block moves downward, causing the rubber pressure plate to squeeze and fix the cuff. When the person moves backward, the sterile garment will automatically detach.
[0016] Compared with the prior art, the beneficial effects of the present invention are: To address the problem that existing technologies lack a systematic auxiliary means to simultaneously adapt to different user body shapes and provide stable support, positioning, and assisted removal of sterile gowns when a single person is putting on and taking off sterile gowns, resulting in poor operational coordination, an unsmooth process, and an increased risk of contamination, this invention addresses this issue by setting up height-adjustable support parts and laterally adjustable cuff support parts. This allows the support positions of the sterile gown body and cuffs to be adjusted according to the user's height and arm span. The same device is used to set up the sterile gown, open the cuffs, and maintain its position during the putting on and taking off process, thus providing a more stable support foundation and a clear operational coordination relationship for the donning and taking off of sterile gowns in single-person scenarios.
[0017] Furthermore, by setting a clamping structure at the cuff support position that can be controlled to lift and reset, the present invention enables the cuff of the sterile garment to be held in a predetermined position during the dressing preparation stage, and to be released, overstepped, and re-secured in conjunction with the forward extension of the arm during the undressing stage. This allows the sterile garment to have a clear and controlled positioning process when it is removed from the body, avoiding the inconvenience caused by relying mainly on the palm to directly assist in removing the garment during single-person undressing. This makes the single-person sterile garment removal process more coherent and reduces the risk of contamination caused by unstable dressing and undressing coordination. Attached Figure Description

[0020] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention. Example 1
[0021] like Figures 1 to 9As shown, a single-person sterile gown donning and doffing assistance device includes an L-shaped base plate 1. Side guardrails 11 are provided on both sides of the L-shaped base plate 1. The side guardrails 11 are arranged along the length of the L-shaped base plate 1 on both sides of the L-shaped base plate 1 to form an integral load-bearing foundation with the L-shaped base plate 1. Columns 12 are symmetrically fixed to the rear side of the back plate of the L-shaped base plate 1. A lifting guide area is formed between the two columns 12. A top plate 14 is fixed to the top of the two columns 12. The top plate 14 and the L-shaped base plate 1 form an installation support space for a screw 13. The screw 13 is horizontally rotatably installed between the L-shaped base plate 1 and the top plate 14, and the screw 13 is located between the two columns 12. A rotating handle 131 is provided on the top of the screw 13. A lifting seat 2 is slidably installed on the two columns 12 and screwed onto the surface of the screw 13. When the rotating handle 131 drives the screw 13 to rotate, the lifting seat 2 slides up and down along the columns 12.
[0022] like Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, a forward extension beam 21 is provided above the front surface of the lifting seat 2. A support hanger 22 is fixed to the front end of the forward extension beam 21. The support hanger 22 is located above the front side of the device and is used to support the sterile gown body. Side extension beams 23 are horizontally provided on the lower sides of the lifting seat 2. T-shaped grooves 24 are opened on the surface of the side extension beams 23. The front and end of the T-shaped grooves 24 are open. Two telescopic plates 3 are slidably installed on the inner side of the corresponding side extension beams 23, and both telescopic plates 3 extend beyond the end face of the corresponding side extension beams 23. A screw 25 is rotatably installed at the center of the lower surface of the lifting seat 2. An adjusting block 4 is screwed onto the surface of the screw 25. First connecting rods 5 are symmetrically hinged on both sides of the adjusting block 4. The ends of the two first connecting rods 5 away from the adjusting block 4 are respectively hinged to the two telescopic plates 3, thus forming a synchronous lateral adjustment mechanism for the two telescopic plates 3.
[0023] like Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, each of the two telescopic plates 3 has a fixing ring 31 below its opposite ends. An arc-shaped cuff support plate 32 is located in front of each fixing ring 31, serving to expand and limit the cuff of the sterile gown. A mounting groove 33 is vertically formed at the end of each telescopic plate 3, located above the center of the fixing ring 31. A pressure block 6 is vertically slidably installed inside the mounting groove 33. A rubber pressure plate 61 is located at the front end of the pressure block 6, positioned above the root of the arc-shaped cuff support plate 32. A fixing bolt 62 is vertically fixed to the upper surface of block 6. The fixing bolt 62 penetrates the upper surface of the telescopic plate 3. A spring 7 is sleeved on the surface of the fixing bolt 62. The spring 7 is located inside the mounting groove 33 and is used to push the pressure block 6 downward. A control ring 8 is rotatably installed on the rear side of the fixing ring 31. A straight rod 81 is fixed on the inner side of the control ring 8. An eccentric bolt 82 is provided on the rear surface of the control ring 8. A second connecting rod 9 is rotatably installed on the surface of the eccentric bolt 82. The end of the second connecting rod 9 away from the control ring 8 is hinged to the back of the pressure block 6, thus forming the opening and closing control structure of the pressure block 6.
[0024] like Figures 1 to 9 As shown, when a single person needs to complete the donning and doffing of sterile gowns and the existing method is difficult to balance support, positioning, and disengagement, the device is first placed in the operating area. Then, by rotating the handle 131, the screw 13 is rotated, and the lifting seat 2 moves up and down along the screw 13 under the guidance of the column 12 to adjust the overall height of the support hanger 22, the side extension beam 23, the telescopic plate 3, and the arc-shaped cuff support plate 32. After the height adjustment is completed, the screw 25 is rotated, and the screw 25 drives the adjusting block 4 to move along the screw 25. During the movement of the adjusting block 4, the two telescopic plates 3 are simultaneously pulled by the first connecting rods on both sides to slide laterally in the corresponding side extension beam 23, thereby adjusting the distance between the two arc-shaped cuff support plates 32 so that the two arc-shaped cuff support plates 32 correspond to the position of the user's arms.
[0025] like Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, after the position adjustment is completed, the sterile gown is placed on the support hanger 22, and the two cuffs of the sterile gown are respectively fitted onto the outer sides of the two curved cuff support plates 32. The pressure block 6 in the mounting groove 33 is in a depressed state under the action of the spring 7, and the rubber pressure plate 61 is located above the root of the curved cuff support plate 32, forming a tight fit between the cuffs fitted onto the curved cuff support plate 32. During the dressing process, the support hanger 22 supports the main body of the sterile gown, the curved cuff support plate 32 unfolds the cuffs, and the rubber pressure plate 61 limits the cuffs, so that the sterile gown is maintained in an arrangement corresponding to the direction of human insertion on the front side of the device.
[0026] like Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, during the undressing process, the user raises both arms and extends them forward along the inside of the two curved cuff support plates 32, with the cuffs remaining on the outside of the curved cuff support plates 32. When the arms reach the predetermined position, the user rotates the lever 81, causing the control ring 8 to rotate. The control ring 8, via the eccentric bolt 82 and the second connecting rod 9, causes the pressure block 6 to move upward within the mounting groove 33. The rubber pressure plate 61 is lifted as the pressure block 6 moves upward. The user then continues to extend their arms forward, allowing the cuffs to enter the area below the rubber pressure plate 61. After releasing the control ring 8, the spring 7 pushes the pressure block 6 downward to reset, and the rubber pressure plate 61 presses down on the cuffs again. At this point, the two cuffs are stably fixed at the curved cuff support plates 32. The user then moves their body backward, separating the sterile gown from the body, completing a full single-person sterile gown removal process. Example 2
[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this embodiment further describes the lifting support and lateral adjustment parts. The L-shaped base plate 1 is located at the bottom of the device, serving as the mounting base for the columns 12, lead screw 13, and lifting seat 2. Two side guardrails 11 are respectively positioned on both sides of the L-shaped base plate 1. Two columns 12 are symmetrically fixed to the rear side of the back plate of the L-shaped base plate 1. The tops of the two columns 12 are fixedly connected via a top plate 14, forming a vertical frame structure between the top plate 14 and the L-shaped base plate 1. The lead screw 13 is horizontally rotatably installed between the L-shaped base plate 1 and the top plate 14, positioned between the two columns 12. A rotating handle 131 is located on the top of the lead screw 13 to allow external force to drive its rotation. The lifting seat 2 simultaneously slides with the two columns 12 and screws with the lead screw 13, thus, when the lead screw 13 rotates, the lifting seat 2 rises and falls synchronously along the two columns 12.
[0028] like Figure 2 , Figure 4 and Figure 5 As shown, the front extension beam 21 is located above the front surface of the lifting seat 2, and the support hanger 22 is fixed to the front end of the front extension beam 21. The support hanger 22 is located in the middle of the front part of the device. The two side extension beams 23 are respectively located on the lower sides of the lifting seat 2. The two side extension beams 23 and the lifting seat 2 form a left-right unfolding arrangement. The T-shaped slide 24 is opened on the surface of the side extension beam 23. The front side and the end of the T-shaped slide 24 are open. The telescopic plate 3 slides into the inside of the side extension beam 23 and moves laterally along the direction of the T-shaped slide 24. The above structure allows the height adjustment of the support hanger 22 and the height adjustment of the telescopic plate 3 to be completed synchronously by the same lifting seat 2, thereby avoiding height misalignment between the main support position of the sterile garment and the cuff support position.
[0029] like Figure 4 , Figure 6 and Figure 7 As shown, the screw 25 is positioned at the center below the surface of the lifting seat 2. The adjusting block 4 is screwed onto the surface of the screw 25. Two first connecting rods 5 are symmetrically arranged on both sides of the adjusting block 4, connecting the adjusting block 4 to the two telescopic plates 3 respectively. When the screw 25 rotates, the adjusting block 4 moves along the axial direction of the screw 25. As the adjusting block 4 moves, it pulls or pushes the two telescopic plates 3 laterally within the corresponding T-shaped slide groove 24 via the two first connecting rods 5. The two telescopic plates 3 move in opposite directions and move synchronously, thereby adjusting the distance between the two fixing rings 31 and the arc-shaped cuff support plate 32. The above-mentioned coordination is used to adapt the device to users of different heights and arm spans under single-person use conditions, ensuring that the main support position of the sterile gown and the cuff support position are adjusted accordingly within the same adjustment system. Example 3
[0030] like Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, this embodiment further explains the cuff support and compression release parts. A fixing ring 31 is positioned below one end of the telescopic plate 3 that is opposite to it. The fixing ring 31 connects to the end of the telescopic plate 3 to form the mounting base for the cuff support. An arc-shaped cuff support plate 32 is positioned in front of the fixing ring 31, located on the forward extension path corresponding to the user's arms. A vertical mounting groove 33 is provided at the end of the telescopic plate 3, located above the center of the fixing ring 31. A pressure block 6 is vertically slidably installed inside the mounting groove 33. A rubber pressure plate 61 is positioned at the front end of the pressure block 6, corresponding vertically to the root of the arc-shaped cuff support plate 32. Therefore, when the pressure block 6 moves up and down, the rubber pressure plate 61 can release or compress the cuff on the outside of the arc-shaped cuff support plate 32.
[0031] like Figure 8 and Figure 9 As shown, the fixing bolt 62 is vertically fixed to the upper surface of the pressure block 6, and the fixing bolt 62 extends upward through the upper surface of the telescopic plate 3. The spring 7 is sleeved on the outside of the fixing bolt 62 and located inside the mounting groove 33. The spring 7 applies a continuous downward force to the pressure block 6, so that the pressure block 6 remains in the pressed-down reset state when there is no external force driving it. The control ring 8 is rotatably installed on the rear side of the fixing ring 31. The straight rod 81 is fixed on the inner side of the control ring 8. The eccentric bolt 82 is set on the rear surface of the control ring 8. One end of the second connecting rod 9 is rotatably installed on the surface of the eccentric bolt 82, and the other end of the second connecting rod 9 is hinged to the back of the pressure block 6. When the control ring 8 rotates, the eccentric bolt 82 moves eccentrically synchronously with the control ring 8, and the second connecting rod 9 drives the pressure block 6 to move up and down in the mounting groove 33.
[0032] like Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, after the cuff is pre-fitted onto the outside of the curved cuff support plate 32, the rubber pressure plate 61 is positioned in the lower pressing position under the push of the spring 7, forming a clamping fit between the rubber pressure plate 61 and the root of the curved cuff support plate 32. When it is necessary for the cuff to pass over the position of the rubber pressure plate 61, the lever 81 is rotated, and the control ring 8 drives the eccentric bolt 82 to rotate. The eccentric bolt 82 causes the pressure block 6 to slide upward via the second connecting rod 9, and the rubber pressure plate 61 moves upward simultaneously, thereby making room for passage above the root of the curved cuff support plate 32. After the cuff moves to the predetermined position, the rotational force on the lever 81 is released, and the pressure block 6 moves downward and resets under the push of the spring 7. The rubber pressure plate 61 presses down again and clamps the cuff. The above structural fit allows the cuff to complete the position change in the action chain of support, release, and re-fixation during the putting on and taking off process, and cooperates with the overall usage process in Example 1 to complete the single-person sterile gown putting on and taking off auxiliary operation.
[0033] The working principle of this invention is as follows: When in use, first place the device in the position of use. The L-shaped base plate 1 supports the entire device. The side guard rods 11 are set on both sides of the L-shaped base plate 1. The columns 12 are fixed to the back side of the back plate of the L-shaped base plate 1. The top plate 14 is fixed to the top of the two columns 12. The screw 13 is horizontally rotatably installed between the L-shaped base plate 1 and the top plate 14. The lifting seat 2 is slidably installed on the two columns 12 and screwed onto the surface of the screw 13, so that the lifting seat 2 can be adjusted in height between the columns 12.
[0034] When it is necessary to adjust the dressing and undressing position according to the user's height, rotate the rotating handle 131 and drive the lead screw 13 to rotate. The screw 13 and the lifting seat 2 rotate together, causing the lifting seat 2 to slide up and down along the surface of the column 12. This allows for the synchronous adjustment of the height of the support hanger 22 at the front end of the front extension beam 21, as well as the overall height of the side extension beams 23 and the telescopic plate 3, so that the support hanger 22 and the arc-shaped cuff support plate 32 are in a position that is suitable for the user.
[0035] Subsequently, when it is necessary to adjust the position of the cuff supports on both sides according to the user's arm span, the screw 25 installed at the center below the surface of the rotating lifting seat 2 can move the adjusting block 4 when the screw 25 rotates, since the adjusting block 4 is screwed onto the surface of the screw 25. During the movement of the adjusting block 4, the first connecting rods 5 symmetrically hinged on both sides of the adjusting block 4 move synchronously and drive the telescopic plates 3 on both sides to slide laterally in the T-shaped slide groove 24 of the corresponding side extension beam 23, so that the two telescopic plates 3 move closer or further away from each other. Since the fixing ring 31 is set below the opposite ends of the two telescopic plates 3 and the arc-shaped cuff support plate 32 is set in front of the fixing ring 31, the position change of the telescopic plate 3 can synchronously change the distance between the two arc-shaped cuff support plates 32 to adapt to the dressing and undressing needs of different users.
[0036] Next, when preparing to put on the garment, the sterile gown is placed on the support hanger 22, and the two cuffs of the sterile gown are respectively placed on the outside of the curved cuff support plates 32 on both sides. Since the curved cuff support plates 32 are located in front of the fixing ring 31 and can support the cuffs, the two cuffs of the sterile gown can remain open under the support of the curved cuff support plates 32, making it easy for the user to put their arms in accordingly.
[0037] After the cuff is fitted onto the curved cuff support plate 32, the pressure block 6, which is vertically slidably installed in the mounting groove 33, is in the corresponding working position. The rubber pressure plate 61 at the front end of the pressure block 6 is located above the root of the curved cuff support plate 32. At the same time, the fixing bolt 62 is fixed to the upper surface of the pressure block 6 and passes through the upper surface of the telescopic plate 3. The spring 7 is fitted on the surface of the fixing bolt 62 and is located inside the mounting groove 33. Therefore, the spring 7 can apply a downward pressing and reset action to the pressure block 6, so that the rubber pressure plate 61 can press down on the cuff located on the curved cuff support plate 32 to fix it, thereby keeping the cuff in the predetermined position during the process of putting on and taking off clothes.
[0038] When the cuff needs to be released or re-secured, the control ring 8, which is rotatably mounted on the back of the fixing ring 31, is rotated. The straight rod 81 fixed inside the control ring 8 is used to apply force. The eccentric bolt 82 on the rear surface of the control ring 8 rotates synchronously with the control ring 8. The eccentric bolt 82 is connected to the back of the pressure block 6 through the second connecting rod 9. Therefore, the rotation of the control ring 8 can be transmitted to the pressure block 6 through the eccentric bolt 82 and the second connecting rod 9, causing the pressure block 6 to move up or down in the mounting groove 33. When the pressure block 6 moves up, the rubber pressure plate 61 is lifted relative to the arc-shaped cuff support plate 32, thereby releasing the cuff. When the control ring 8 is released, the pressure block 6 moves down and resets under the action of the spring 7, and the rubber pressure plate 61 re-presses and secures the cuff.
[0039] During the undressing process, the user first raises both arms and extends them forward along the inside of the two curved cuff support plates 32. During this extension, the sterile garment cuffs remain fitted onto the curved cuff support plates 32. Then, when the arms reach the predetermined length, the user rotates the control ring 8 via the lever 81. The rotation of the control ring 8 causes the eccentric bolt 82 to move the pressure block 6 upward via the second connecting rod 9, thereby raising the rubber pressure plate 61 so that the cuffs can further pass through the corresponding position.
[0040] Next, extend the arm forward until the cuffs of the sterile gown are positioned below the rubber pressure plate 61. Then, release the control ring 8, and the pressure block 6 moves downward and resets under the action of the spring 7. The rubber pressure plate 61 then presses down on the cuffs again, stably squeezing and fixing the two cuffs in their corresponding positions. At this point, the user moves their body backward, and the sterile gown separates from the body with the cuffs fixed, thus achieving automatic detachment of the sterile gown and completing one single-person sterile gown donning and doffing assistance process.
[0041] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
