Description

Technical Field

[0001] The invention relates to the technical field of vaginal B-ultrasound, and in particular to an automatic condom-donning device for a vaginal ultrasound probe. Background Art

[0002] Vaginal ultrasound, also known as intracavitary ultrasound, is a method of ultrasound diagnosis in which the ultrasound probe is placed in the vagina or rectum. It is suitable for observing pelvic organs in the small pelvis. Compared with abdominal ultrasound, the image of vaginal ultrasound is clearer and more realistic, the results are more accurate, and the examinee does not need to hold urine. Vaginal ultrasound examination is suitable for a variety of diagnoses, such as pregnancy examination, uterine space-occupying diseases, ovarian tumors, etc.

[0003] The bladder needs to be emptied before transvaginal ultrasound examination, and the patient takes the lithotomy position. The doctor will wear disposable gloves, apply ultrasonic coupling agent on the surface of the probe, put on a protective cover, and then insert it into the body for examination. Accurate images of the uterus and ovaries can be obtained at close range, which is more intuitive for diagnosing uterine and adnexal diseases.

[0004] There are still certain shortcomings in the existing vaginal ultrasound operation process. In order to ensure the hygiene of the operation process, medical staff need to wear disposable gloves and wear disposable protective covers on the vaginal ultrasound probe. However, the disposable gloves and protective covers are affected by their own materials and the oil used for lubrication on the outside of the protective cover, which makes the gloves and the protective covers very slippery, making it inconvenient to wear the protective covers. Secondly, before putting on the protective cover for the vaginal ultrasound probe, it is necessary to apply coupling agent to the end of the vaginal ultrasound probe to fill the gap between the probe and the protective cover, making the entire cover-donning operation more cumbersome. After completing the putting on of the protective cover, medical staff also need to operate the vaginal ultrasound-related operating equipment. The residual oil on the outside of their gloves due to the previous operation of putting on the protective cover will also cause the keyboard and screen of the equipment to be contaminated with oil, causing pollution. Therefore, the present application provides an automatic cover-donning device for a vaginal ultrasound probe to meet the needs. Summary of the invention

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above scheme, by setting up a pulling component and a storage tube, the automatic condom-donning device for the vaginal ultrasound probe can, under the premise of ensuring hygiene, stack the torn-off protective covers in the storage tube in advance, and rely on the pulling component to pull out the stacked protective covers in the storage tube one by one and form a taut state. The vaginal ultrasound probe can be automatically donned by simply inserting the vaginal ultrasound probe directly into the device, making the condom-donning operation of the vaginal ultrasound probe simple and convenient, and will not cause cross infection, which complies with medical and health standards.

[0019] By setting the arc-shaped elbow in the pulling component, when the vaginal ultrasound probe is pressed down to put on the cover, after the taut protective cover is pressed down to a certain extent, the pulling component can be deformed at the third weakened groove and the position of the arc-shaped elbow can be shifted, thereby releasing the pulling and tightening state of the protective cover and allowing the protective cover to recover its deformation under the action of its own elastic force, thereby making the structure of the entire pulling component simple, the cost controllable, and the protective cover will not be damaged during the pulling process.

[0020] During the insertion process of the vaginal ultrasound probe, a guide component is set to limit and guide the vaginal ultrasound probe, so that the end of the vaginal ultrasound probe is guided to the protective cover and pulled to a taut position, so that the entire vaginal ultrasound probe automatic cover-donning device can be used accurately and quickly, and is easy for medical staff to use, thereby indirectly improving the work efficiency of medical staff.

[0021] By setting up an extrusion component, the guide component can limit and guide the vaginal ultrasound probe during the insertion process while driving the extrusion component to work, so that before the end of the vaginal ultrasound probe contacts the protective cover, the coupling agent in the storage box is squeezed out and drips to the middle of the protective cover. After the end of the vaginal ultrasound probe contacts the middle of the protective cover, the end of the vaginal ultrasound probe is directly coated, so that the condom wearing operation can be combined with the extrusion and coating operation of the coupling agent, further simplifying the entire condom wearing operation process. At the same time, the extrusion component and the guide component in the device are coordinated, making the entire technical solution more complete.

[0022] By setting the extrusion hole and the sealing elastic sheet in the extrusion assembly, when the vaginal ultrasound probe is not inserted into the device, the sealing elastic sheet is used to seal the coupling agent stored in the extrusion cavity to prevent the coupling agent from leaking out. When the coupling agent is extruded, the sealing elastic sheet can be opened under pressure to allow the coupling agent to be discharged along the inclined extrusion hole, so that the coupling agent can drip accurately onto the protective cover, further improving the function of the extrusion assembly.

[0046] like Figures 1 to 14As shown, an embodiment of the present invention provides an automatic condom-donning device for a vaginal ultrasound probe, comprising a sterile box 1 and a vaginal ultrasound probe 9. A first closing cover 2 is sleeved on the top of the sterile box 1, and the first closing cover 2 is used to close the top of the sterile box 1. When it is necessary to clean and sterilize the interior of the sterile box 1 and the structure below the first closing cover 2, the first closing cover 2 can be removed to expose the structure inside the sterile box 1, which is convenient for cleaning and sterilization. An insertion port 10 that matches the size of the vaginal ultrasound probe 9 is opened in the middle of the first closing cover 2, and a mounting frame 12 is fixedly connected to the bottom of the first closing cover 2. The vaginal ultrasound probe 9 can be inserted into the sterile box 1 from the insertion port 10 in the middle of the first closing cover 2. A storage box 13 and a storage tube 14 are sleeved in the mounting frame 12. A through port 3 that corresponds to the position of the insertion port 10 and is consistent with the size is opened in the middle of the storage box 13. 3. After the vaginal ultrasound probe 9 is inserted into the sterile box 1 from the insertion port 10, it can enter the through port 33 on the inner side of the storage box 13, and is guided and limited by the structure located on the inner side of the through port 33. The interior of the storage box 13 is a hollow structure; a closing component is used to seal and protect the sterile box 1, and the closing component is connected to the first closing cover 2; a limiting component is used to limit the protective cover stored in the storage tube 14, and the limiting component is connected to the storage tube 14; a pulling component is used to pull the protective cover in the storage tube 14 to a taut state, and the pulling component is connected to the sterile box 1; a guiding component is used to guide and limit the vaginal ultrasound probe 9 entering the sterile box 1, and the guiding component is connected to the interior of the storage box 13; an extrusion component is used to extrude the coupling agent stored in the storage tube 14, and the extrusion component is arranged in the guiding component.

[0047] In this embodiment, if Figures 2 to 6As shown, the closure assembly includes a buckle 6 fixedly connected to the first closure cover 2 around, a second weakened groove 20 is provided in the middle of the buckle 6, and the bottom end of the buckle 6 is bent toward the outside of the sterile box 1, and the first closure cover 2 and the sterile box 1 are connected and fixed by the buckle 6. The part of the bottom end of the buckle 6 bent toward the outside of the sterile box 1 makes it possible for a certain gap to exist between the end of the buckle 6 and the outer surface of the sterile box 1 after the first closure cover 2 is connected and fixed to the sterile box 1, so that it is convenient for medical staff to insert and move their fingers, and it is easy to disassemble the first closure cover 2. A buckle head 21 is provided on the side of the buckle 6 facing the outside of the sterile box 1, and a groove 21 having a shape similar to that of the buckle head 21 is provided on the outside of the sterile box 1. The adapted buckle groove 24, in the fixed state, the buckle head 21 on the buckle 6 is engaged with the buckle groove 24 on the outside of the sterile box 1, maintaining the connection and fixed state between the sterile box 1 and the first closing cover 2, the bottom of the first closing cover 2 is fixedly connected with a sealing ring 11, and the inner wall of the sterile box 1 is provided with a sealing groove 22 adapted to the shape of the sealing ring 11. When the first closing cover 2 and the sterile box 1 are in a connected and fixed state, the sealing ring 11 at the bottom of the first closing cover 2 enters the inner side of the sterile box 1, and is docked and fitted with the sealing groove 22 provided in the sterile box 1, so as to block the gap at the connection between the first closing cover 2 and the sterile box 1, and improve the sealing performance of the sterile box 1 and the first closing cover 2 after the connection and fixation.

[0048] In this embodiment, if Figures 2 to 3 As shown, the top of the first closing cover 2 is movably sleeved with a rotating shaft 16, and the outside of the rotating shaft 16 is fixedly connected with the second closing cover 3. The rotating shaft 16 is movably connected to the first closing cover 2 and can rotate at the top of the first closing cover 2. The second closing cover 3 can deflect under the action of the rotating shaft 16, so as to achieve the closure of the insertion port 10. The middle part of the second closing cover 3 is bent and provided with a first weakened groove 5. The bent part in the middle part of the second closing cover 3 makes the middle part of the second closing cover 3 form a bent structure similar to a handle, which is easy to release the connection and fixing relationship between the first closing cover 2 and the sterile box 1 by the buckle 6, and then lift the second closing cover 3 to lift the first closing cover 2 as a whole. At the same time, the design of the first weakened groove 5 makes the second closing cover 3 The thickness at this location is thinner, the strength is weaker, and it is easy to deform. The shape of one end of the second closing cover 3 away from the rotating shaft 16 is adapted to the shape of the insertion port 10, and a paddle 4 is fixedly connected above the end of the second closing cover 3 away from the rotating shaft 16. Plugging the paddle 4 can make the second closing cover 3 bend and deform at the first weakened groove 5, so that the end of the second closing cover 3 closing the insertion port 10 is pulled open, exposing the insertion port 10, and facilitating the insertion of the vaginal ultrasound probe 9. A temporary storage groove 51 adapted to the shape of the second closing cover 3 is provided on the first closing cover 2. The temporary storage groove 51 provided on the first closing cover 2 can temporarily store the end of the second closing cover 3 when the vaginal ultrasound probe 9 is inserted into the device through the insertion port 10.

[0049] In this embodiment, if Figures 10 to 12 As shown, the limiting assembly includes two supporting plates 40 symmetrically installed on the inner side of the bottom end of the storage tube 14. The protective covers after being torn off the package are stacked and stored on the inner side of the storage tube 14, and are supported and limited by the two supporting plates 40. The protective covers are affected by their own gravity, and the areas not supported by the supporting plates 40 will fall downward under the action of their own gravity. A fourth weakening groove 41 is provided on the outside of the supporting plate 40. The fourth weakening groove 41 on the outside of the supporting plate 40 makes the supporting plate 40 thinner and weaker at this location, so that when the protective cover is pulled by external force, the supporting plate 40 can move downward to a certain extent at the fourth weakening groove 41. The bottom of the storage tube 14 is provided with a second avoidance buckle 42 which is staggered with the supporting plate 40, and the depth value of the second avoidance buckle 42 is the same as the thickness value of the supporting plate 40. The setting of the second avoidance buckle 42 enables the bottom structure of the storage tube 14 to avoid the pulling component, so that the pulling component is convenient to enter the bottom of the storage tube 14 and contact with the protective cover. When the protective cover is naturally supported, its supporting area corresponds to the opening area of ​​the second avoidance buckle 42, so that the pulling component can contact the protective cover after entering from the second avoidance buckle 42.

[0050] In this embodiment, if Figure 2 and Figure 5 as well as Figure 8 and Fig.12 As shown, the pulling assembly includes an electric push rod 15 sleeved on the inner side of the sterile box 1 and a first fixing seat 27 fixedly connected to the inner wall of the sterile box 1. The position of the electric push rod 15 is symmetrically distributed in the sterile box 1 with the first fixing seat 27. The outside of the sterile box 1 is fixedly connected to a controller 8 electrically connected to the electric push rod 15. The operation of the controller 8 can control the electric push rod 15 to work. The outside of the controller 8 is provided with an operation button. The working principle and installation method of the controller 8 and the electric push rod 15 are the same as those of the prior art, and will not be described in detail here. The first A movable sleeve in the fixed seat 27 is provided with a first sliding plate 26, and the end of the first sliding plate 26 is fixedly connected to the second hook 25. The storage box 13 and the storage tube 14 are assembled on the axis of the sterile box 1. The pendant area of ​​the protective cover located at the bottom layer in the storage tube 14 falls directly on the second hook 25 and is hooked by the second hook 25. The end of the driving rod of the electric push rod 15 is fixedly connected to the first hook 23. When the electric push rod 15 is working, it can drive the first hook 23 to move through its driving rod, so that the first hook 23 moves to the bottom of the storage tube 14 and hooks the pendant part of the protective cover.

[0051] In this embodiment, if Figures 5 to 9As shown, a guide block 31 is arranged outside the first sliding plate 26, and an active cavity 32 which is adapted to the shape of the first sliding plate 26 and the guide block 31 is opened in the first fixed seat 27. The first sliding plate 26 can slide on the inner side of the first fixed seat 27. During the sliding process, the guide block 31 and the active cavity 32 are kept in a sleeve state, providing guidance and limiting for the sliding of the first sliding plate 26, so as to prevent the first sliding plate 26 from being completely withdrawn from the first fixed seat 27, and a first spring 34 is fixedly connected between the first sliding plate 26 and the active cavity 32. The first spring 34 can limit the first sliding plate 26 by its own elastic force, so that the second hook 25 and When the first sliding plate 26 is not subjected to external force, the first sliding plate 26 can be retracted in the first fixing seat 27, and the position of the second hook 25 is kept corresponding to the position of the second avoidance buckle 42 at the bottom of the storage tube 14 near the second hook 25, so as to hook the pendant area on one side of the protective cover. The outside of the first hook 23 and the second hook 25 are both provided with a third weakening groove 29. The third weakening groove 29 makes the thickness of the first hook 23 and the second hook 25 thinner at this location, and the structural strength is weaker. After being subjected to a large external force, they can be deformed, and the ends of the first hook 23 and the second hook 25 are bent toward the direction of the third weakening groove 29 to form an arc elbow 30. During the retraction of the electric push rod 15, the arc elbow 30 area on the first hook 23 and the second hook 25 remains connected to the outer ring part of the protective sleeve, and the second hook 25 is subjected to a pulling force toward the storage cylinder 14, thereby driving the first sliding plate 26 to be pulled out from the first fixing seat 27 and stretching the first spring 34 until the first sliding plate 26 is pulled out from the first fixing seat 27 to a maximum value, and then the electric push rod 15 continues to retract. Since the first sliding plate 26 cannot continue to move, the protective sleeve is deformed under the pulling action of the first hook 23 and the second hook 25, and is pulled tight, and the center area is kept aligned with the center area of ​​the through hole 33. When the end of the vaginal ultrasound probe 9 is pressed down to contact the protective cover, the continuous downward pressure can generate downward pressure on the protective cover and the first hook 23 and the second hook 25, thereby causing the first hook 23 and the second hook 25 to bend and deform at the third weakened groove 29 until the edge of the protective cover is separated from the arc elbow 30 at the end of the first hook 23 and the second hook 25. At this time, the protective cover is released from the tensioned state and recovers its deformation under the action of its own elasticity, so as to fit the outside of the vaginal ultrasound probe 9, thereby realizing the operation of putting on the cover of the vaginal ultrasound probe 9. The outside of the first hook 23 and the second hook 25 are both arc-shaped curved surface structures to avoid damage to the protective cover during the pulling process.

[0052] In this embodiment, if Figures 10 to 13As shown, the guide assembly includes a second fixing seat 35 fixedly connected to the inner wall of the storage box 13, there are four groups of second fixing seats 35, and the four groups of second fixing seats 35 are evenly distributed in the storage box 13, the second fixing seats 35 are fixedly connected to the inner wall of the storage box 13, and other structures of the unguided assembly provide a stable installation position, the outer sleeve of the second fixing seat 35 is provided with a second sliding plate 36, and the second fixing seat 35 and the second sliding plate 36 are fixedly connected with evenly distributed second springs 48, one side of the second sliding plate 36 facing the center direction of the storage box 13 extends into the through hole 33 and is fixedly connected with a second limiting plate 43, and the second sliding The plate 36 can move in the second fixed seat 35, and can drive the second limiting plate 43 to move during the movement, thereby changing the position of the second limiting plate 43 in the through hole 33, and the outside of the second sliding plate 36 is fixedly connected to the third limiting plate 47 located inside the storage box 13, and the second spring 48 between the second fixed seat 35 and the second sliding plate 36 can limit the second sliding plate 36 by its own elastic force, and the second limiting plate 43 can maintain the fitting state between the third limiting plate 47 and the inner side wall of the storage box 13 when no external force is applied, thereby realizing the limiting of the second limiting plate 43, and the outside of the second limiting plate 43 is provided with a third limiting plate 47 that is in contact with the vaginal ultrasound probe 9 The second limiting plate 43 has a curved surface that matches the outer shape of the rod body, and the top and bottom of the second limiting plate 43 are respectively provided with a first guiding surface 44 and a second guiding surface 45. During the insertion of the vaginal ultrasound probe 9 into the through-port 33, when the end of the vaginal ultrasound probe 9 passes through the through-port 33, the rod body portion of the vaginal ultrasound probe 9 is in the through-port 33, and the second spring 48 can squeeze the second sliding plate 36 through its own elastic force, so that the second sliding plate 36 drives the second limiting plate 43 to maintain contact with the outer part of the rod body of the vaginal ultrasound probe 9, providing guidance for the downward movement of the vaginal ultrasound probe 9. The curved surface on the outside of the second limiting plate 43 can increase the contact with the outer part of the rod body portion of the vaginal ultrasound probe 9. The contact area can ensure the guiding and limiting effect of the second limiting plate 43. The first guiding surface 44 and the second guiding surface 45 on the second limiting plate 43 can first contact with the end part of the vaginal ultrasound probe 9 when the vaginal ultrasound probe 9 is pressed downward or pulled out upward, and decompose the resistance encountered by the vaginal ultrasound probe 9 during the movement through its own inclined structure, and decompose a part of the vertical resistance encountered by the vaginal ultrasound probe 9 through the inclined surface structure to form a lateral thrust on the second limiting plate 43, and then reduce the resistance during the movement of the vaginal ultrasound probe 9 through the movement of the second limiting plate 43, so as to facilitate the insertion of the vaginal ultrasound probe 9 into the device and the extraction after the condom operation is completed.

[0053] In this embodiment, if Figures 10 to 14As shown, the extrusion assembly includes an extrusion cavity 46 opened in the second limiting plate 43 and an extrusion seat 39 fixedly connected to the inner side wall of the storage box 13, the extrusion cavity 46 is adapted to the shape of the extrusion seat 39, and the position of the extrusion cavity 46 and the extrusion seat 39 corresponds to each other, and the second limiting plate 43 is provided with an extrusion hole 49 connected with the extrusion cavity 46 on the outside, and during the insertion of the vaginal ultrasound probe 9 into the device, the second limiting plate 43 is squeezed and moved by the vaginal ultrasound probe 9, and then the extrusion seat 39 is inserted into the extrusion cavity 46 at the corresponding position, so that the coupling agent in the extrusion cavity 46 is squeezed by the extrusion seat 39, and the extrusion hole 49 is inclined downward toward one end of the center position of the through hole 33, and a sealing elastic sheet 50 is sleeved in the extrusion hole 49, and the sealing elastic sheet 50 is made of a circular elastic silicone sheet, and a cross-shaped gap is opened in the middle of the sealing elastic sheet 50, and when the extrusion seat 39 enters the extrusion cavity 46 and squeezes the coupling agent in the extrusion cavity 46, the sealing elastic sheet 50 is squeezed by the coupling agent. The coupling agent stored in the extrusion cavity 46 flows out due to the inclined setting of the extrusion hole 49. The coupling agent flowing out can drip along the inclined direction on the middle part of the protective cover maintained in a taut state by the pulling component, waiting for contact with the end of the vaginal ultrasound probe 9. The extrusion cavity 46 is provided with an opening on the side facing the extrusion seat 39, and a gap is provided between the opening of the extrusion cavity 46 and the extrusion seat 39. When the second limiting plate 43 is not subjected to external force, it is limited only by the elastic force of the second spring 48. At this time, there is a certain gap between the opening of the extrusion cavity 46 and the extrusion seat 39, which can facilitate the coupling agent to leak into the extrusion cavity 46 and replenish the coupling agent waiting to be extruded in the extrusion cavity 46. When the vaginal ultrasound probe 9 is pressed down to contact with the taut protective cover, the end part of the vaginal ultrasound probe 9 can contact and fit with the coupling agent dripping on the center part of the protective cover, thereby covering and wrapping the outside of the end of the vaginal ultrasound probe 9 and filling the gap between the end of the vaginal ultrasound probe 9 and the protective cover.

[0054] In this embodiment, if Figures 2 to 3As shown, the connection between the mounting frame 12 and the first closing cover 2 is bent toward the outside of the first closing cover 2 and forms an escape area 52. The setting of the mounting frame 12 can form an assembly space for the storage box 13 and the storage cylinder 14 below the first closing cover 2, so that the storage box 13 and the storage cylinder 14 are associated with the first closing cover 2, and the storage box 13 and the storage cylinder 14 can be assembled in the sterile box 1 while the first closing cover 2 is assembled. The setting of the escape area 52 allows a larger space to exist between the top of the storage box 13 and the storage cylinder 14 and the first closing cover 2, which is convenient for medical staff to add coupling agent in the storage box 13 and protective cover in the storage cylinder 14. The bottom of the mounting frame 12 is provided with a first escape opening 18 that can accommodate the vaginal ultrasound probe 9 and the electric push rod 15 as well as the first hook 23 and the second hook 25, and the bottom end of the mounting frame 12 is fixedly connected with a uniform The distributed legs 19 and the opening of the first avoidance opening 18 allow sufficient space at the bottom of the mounting frame 12 to facilitate the downward movement of the vaginal ultrasound probe 9, and allow the entire pulling assembly to move under the mounting frame 12, pulling the protective cover tight to a position corresponding to the downward movement of the vaginal ultrasound probe 9, and a support 28 that is adapted to the shape of the legs 19 is fixedly connected to the inner wall of the sterile box 1. The legs 19 at the bottom of the mounting frame 12 can support the mounting frame 12 and the first closing cover 2 as a whole when the mounting frame 12 is pulled out of the sterile box 1 as a whole and placed on the platform, thereby reducing the contact area between the bottom of the mounting frame 12 and the platform and reducing contamination caused by contact. The support 28 in the sterile box 1 can dock with the legs 19 after the mounting frame 12 is assembled in the sterile box 1, thereby further improving the stability of the mounting frame 12 and the structure in the mounting frame 12 when assembled and fixed in the sterile box 1.

[0055] In this embodiment, if Figure 2 and Figure 3 as well as Fig.10As shown, the mounting frame 12 is U-shaped as a whole, and two groups of mounting seats 17 are symmetrically installed on the inner side wall of the mounting frame 12. The U-shaped structure of the mounting frame 12 forms an assembly space for the storage box 13 and the storage cylinder 14 on the inner side of the mounting frame 12, and can protect the storage box 13 and the storage cylinder 14. The storage box 13 and the storage cylinder 14 are fixedly connected to the outside with a first limiting plate 37 that is adapted to the shape of the mounting seat 17. The end of the first limiting plate 37 is inclined toward the inner side wall of the mounting frame 12, and the outside of the first limiting plate 37 is provided with a fifth weakening groove 38, and the fifth weakening groove 38 makes The first limiting plate 37 is thinner and weaker at this location, and is prone to deformation. The storage box 13 and the storage tube 14 are connected to the mounting frame 12 through the mounting seat 17 and the first limiting plate 37, so that the storage box 13 and the storage tube 14 can be disassembled and separated from the mounting frame 12, further facilitating the cleaning and disinfection operations of various structures in the entire device. In the separated state, the distance between the ends of the two sets of first limiting plates 37 outside the storage box 13 and the storage tube 14 is greater than the length of the top end of the mounting seat 17. When installing, the two first limiting plates 37 can be pinched together so that the two first limiting plates 37 are The limiting plate 37 is deformed and bent at the fifth weakened groove 38 until the distance between the ends of the two first limiting plates 37 is less than the length value of the top entrance of the mounting seat 17. Then the two first limiting plates 37 are inserted into the inner side of the mounting seat 17 and loosened. The first limiting plates 37 recover their deformation under the action of their own elastic force and are squeezed and fitted on the inner side wall of the mounting seat 17 to achieve the connection and fixation between the storage box 13 and the storage cylinder 14 and the mounting frame 12. A liquid level display window is provided on the outside of the storage box 13, a protective cover observation port is provided on the outside of the storage cylinder 14, and a liquid level display window is provided on the outside of the sterile box 1 The liquid level display window and the protective cover observation port correspond to the observation area 7, the setting of the liquid level display window can cooperate with the observation area 7 to facilitate medical staff to observe the remaining coupling agent in the storage box 13, and the protective cover observation port cooperates with the observation area 7 to facilitate medical staff to observe the remaining protective cover in the storage tube 14. A filling port is provided on the top of the storage box 13, and the outside of the filling port is closed by a sealing cover. The filling port on the top of the storage box 13 can be opened by rotating the sealing cover to facilitate the addition of coupling agent. The top of the storage tube 14 is designed to be a trumpet-shaped opening, which expands the area at the entrance of the storage tube 14 and facilitates the insertion of the protective cover.

[0056] The working principle provided by the present invention is that when in use, the protective cover of the torn outer packaging is pre-filled, the end of the buckle 6 is moved to make the buckle head 21 withdraw from the buckle groove 24, the lock of the first closing cover 2 is released, the first closing cover 2 together with the mounting frame 12 is taken out from the sterile box 1 as a whole, and placed stably, the protective cover after the package is torn is placed in the storage tube 14, the input port of the storage box 13 is opened, and the coupling agent is poured into the storage box 13, and the interior of the sterile box 1 and the exterior of the first closing cover 2 and the mounting frame 12 are sterilized. After the treatment, the mounting frame 12 is placed in the sterile box 1, and the first closing cover 2 is closed at the opening at the top of the sterile box 1 until the sealing ring 11 is docked with the sealing groove 22, and the buckle head 21 is clamped on the outside of the buckle groove 24, and the sterile box 1 and the first closing cover 2 are connected and fixed.

[0057] When it is necessary to put on the protective cover for the vaginal ultrasound probe 9, the paddle 4 is pushed to drive the second closing cover 3 to deform at the first weakened groove 5, and the paddle 4 is pulled to make the second closing cover 3 deflect around the rotation axis 16 to the temporary storage groove 51 as a whole and then released. The second closing cover 3 recovers its deformation under the action of its own elastic force and snaps into the temporary storage groove 51, opening the insertion port 10, and the operation controller 8 controls the electric push rod 15 to start, which drives the first hook 23 to move to the bottom of the storage tube 14. At this time, the second closing cover 3 is located at the storage tube 14. The edge area of ​​the bottom protective cover in the storage cylinder 14 is respectively sleeved in the arc elbow 30 at the end of the first hook 23 and the second hook 25, and then the electric push rod 15 is retracted, and the protective cover is pulled by the first hook 23 and the second hook 25. During the pulling process, the second hook 25 drives the first sliding plate 26 to slide in the first fixed seat 27 and stretch the first spring 34 until the first hook 23 and the second hook 25 tighten the protective cover and make the middle of the tightened protective cover correspond to the center position of the through hole 33.

[0058] Insert the vaginal ultrasound probe 9 from the insertion port 10, and the end of the vaginal ultrasound probe 9 enters the sterile box 1 and is inserted into the through port 33 in the storage box 13. During the process of passing through the through port 33, the vaginal ultrasound probe 9 contacts the first guide surface 44 at the top of the second limiting plate 43, slides along the guide of the first guide surface 44 and squeezes the second limiting plate 43 and the first guide surface 44. The second limiting plate 43 drives the second sliding plate 36 to slide in the second fixed seat 35. At the same time, the displacement of the second limiting plate 43 causes the extrusion seat 39 to be inserted into the extrusion cavity 46, and the coupling agent in the extrusion cavity 46 is squeezed. The extruded coupling agent opens the cross-shaped gap in the middle of the sealing elastic sheet 50, and is discharged through the extrusion hole 49 and drips to the center position of the tightened protective cover.

[0059] As the vaginal ultrasound probe 9 is continuously pressed downward, the end portion of the vaginal ultrasound probe 9 passes through the bottom of the through-port 33, and the rod portion above the end of the vaginal ultrasound probe 9 overlaps with the distribution area of ​​the second limiting plate 43. The second limiting plate 43 remains in contact with the outside of the rod portion of the vaginal ultrasound probe 9 under the action of the elastic force of the second spring 48, guiding and limiting the downward movement of the vaginal ultrasound probe 9, and keeping the end position of the vaginal ultrasound probe 9 corresponding to the center position of the tightened protective cover.

[0060] Afterwards, the vaginal ultrasound probe 9 continues to be pressed downward, and the end area of ​​the vaginal ultrasound probe 9 fits with the middle area of ​​the tightened protective cover and contacts with the coupling agent that has dripped before. Under the pressure of the vaginal ultrasound probe 9 and the deformation of the protective cover itself, the coupling agent is squeezed and evenly covers the outer end of the vaginal ultrasound probe 9. After continuing to press the vaginal ultrasound probe 9 downward, under the action of the downward pressure of the vaginal ultrasound probe 9, the tightened protective cover pulls the first hook 23 and the second hook 25, so that the first hook 23 and the second hook 25 are bent and deformed at the third weakened groove 29 until the edge position of the protective cover slides out of the arc elbow 30, releasing the pulled and tightened state of the protective cover. After the pulling is released, the protective cover immediately restores its deformation under the action of its own elastic force, fits and wraps around the outer end of the vaginal ultrasound probe 9, and then the vaginal ultrasound probe 9 is directly pulled out of the sterile box 1 as a whole, and the second closing cover 3 is deflected in the reverse direction to close the insertion port 10, completing the use process of the entire vaginal ultrasound probe automatic condom device.
