[0016] Furthermore, the spray pipe is arc-shaped, and the curvature of the spray pipe is equal to the upper side of the expander upper plate and the lower side of the expander lower plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. When the expander needs to be lubricated, insert the expander upper piece and the expander lower piece into the opening of the sleeve at the same time, and slide and contact with the expander upper piece and the expander lower piece through the guide hole, guide the expander upper piece and the expander lower piece respectively to prevent the expander from deviating from the track, then extend the expander into the sleeve until the end of the expander upper piece or the expander lower piece contacts the push plate, and push the drive block to slide on the sleeve, through the cooperation between the push block, the slide groove, the drive arm, the first column, the drive arm, and the valve stem, drive the valve plate to rotate on the valve body, thereby changing the opening and closing relationship of the valve, so that the lubricant can be normally in the infusion pipeline The liquid flows upward and enters the spray pipe from several inlets in turn, and is sprayed on the surfaces of the upper and lower pieces of the dilator respectively through several atomizing heads arranged on the spray pipe. Compared with the application of paraffin oil lubricant cotton balls, the lubricant adhesion area is greatly increased, the effect of lubricating the dilator is improved, and the use of the same paraffin oil lubricant cotton ball to apply different dilator tips is avoided, thereby reducing the risk of cross infection. At the same time, the lubricant can be refined through the atomizing head, so that the lubricant is fully sprayed on the upper and lower pieces of the dilator, further improving the effect of lubricating the dilator and improving the patient's experience.

[0019] In addition, there is no need for individuals to hold a paraffin oil lubricant cotton ball to apply to the top of the dilator. It is only necessary to move the dilator and press the push plate to spray the dilator, which simplifies the operation steps of lubricating the dilator and improves the efficiency of lubricating the dilator.

[0020] 2. When the opening and closing angle of the valve needs to be adjusted, the fixed block is moved to the left, and the restriction of the fixed block on the rotation of the adjusting block is released through the cooperation among the second spring, the ball, the groove, the second spring, the fixed block, the L-shaped block, the second convex block and the second groove. Then the adjusting block is rotated on the guide rod. Since the adjusting block is threadedly connected with the screw, the adjusting block slides on the screw, changing the restriction range of the driving block sliding on the sleeve, thereby limiting the maximum opening angle of the valve plate, controlling the flow rate of the lubricant, making the flow rate of the lubricant in a suitable range, so that the lubricant can be evenly dispersed into small droplets, making the spray coverage wider and more uniform, thereby improving the effect of the lubricating expander;

[0021] After adjusting the opening and closing angle of the valve, the fixed block is pushed back to the right to return to the starting position. At this time, the fixed block contacts the adjusting block again. At the same time, the L-shaped block, the second protrusion, the second groove, the fixed block, the first protrusion, the guide rod and the first groove cooperate to limit the rotation of the adjusting block on the guide rod. The threaded connection between the adjusting block and the guide rod is used to limit the sliding of the adjusting block on the guide rod, so as to avoid the external force from accidentally pushing the adjusting block to rotate, resulting in a change in the maximum opening angle of the valve, thereby improving the effect of the lubrication expander; at the same time, the ball is reset under the action of the second rebound force, and the resistance generated by the contact between the ball and the groove will limit the sliding of the fixed block relative to the adjusting block, so as to avoid the external force from accidentally pushing the fixed block to move, resulting in a change in the maximum opening angle of the valve, thereby further improving the effect of the lubrication expander.

[0022] 3. When the initial position of the push plate needs to be adjusted, the handle is rotated by applying a force that overcomes the action of the fourth spring. Through the cooperation between the fixed rod, the conical surface, and the limit hole, the handle can continue to rotate on the sliding sleeve until the inclined surfaces on the left and right sides of the limit rod contact the left and right sides of the notch respectively. Then, the sliding sleeve is slid on the sleeve relative to the driving block. The component force generated after the inclined surface contacts the notch drives the limit rod to move toward both sides, so that the sliding sleeve can slide relative to the driving block, driving the push plate to move to the required area, ensuring that the expander can smoothly contact the push plate, and driving the valve to open, so that the infusion pipeline can smoothly transport the lubricant, and the lubrication of the expander is realized;

[0023] In addition, after adjusting the position of the push plate, the reset handle is used to make the planes on the front and rear sides of the limit rod contact the notch. The resistance generated by the contact between the two will limit the further movement of the sliding sleeve relative to the driving block, thereby preventing the external force from accidentally driving the sliding sleeve to move and changing the starting position of the push plate, resulting in the expander being unable to contact the push plate smoothly, and the valve being unable to be fully opened, affecting the effect of the spray expander, or the expander being in contact with the push plate too early, and the entire top of the expander being unable to be inserted into the sleeve, resulting in some areas being unable to be lubricated; at the same time, the resistance generated by the contact between the conical surface at the end of the fixed rod and the limit hole can prevent the handle from being accidentally pushed to move by external force, thereby further improving the stability of the overall structure, thereby improving the effect of lubricating the expander and improving the patient's experience;

[0024] 4. When it is necessary to significantly change the positions of multiple spray pipes relative to the sleeve, the screw rod is loosened so that the multiple protrusions provided at the end of the screw rod no longer contact the arc plate, so that the arc plate can slide smoothly on the sleeve and contact the corresponding columns through the multiple inclined grooves provided on the arc plate. The component force generated simultaneously drives the multiple sliding rods to slide on the fixed plate, and transmits the component force through the fixed plate, the rotating shaft, the rotating plate and the second column to drive the support rod to slide on the sleeve, thereby adjusting the positions of multiple spray pipes on the same side on the sleeve at the same time, so that the atomizing head provided at the end of the spray pipe can fully spray the top of the expander, thereby improving the effect of lubricating the expander; after adjusting the positions of multiple spray pipes, the screw rod is tightened so that the multiple protrusions provided at the end of the screw rod contact the arc plate again, and the friction force generated after the contact will limit the sliding of the arc plate on the sleeve, thereby preventing the external force from accidentally pushing the arc plate, changing the position of the spray pipe on the sleeve, affecting the effect of spraying the top of the expander, and further improving the effect of lubricating the expander;

[0025] 5. When it is necessary to slightly change the position of a single spray pipe relative to the sleeve, press the handle provided on the corresponding spray pipe, and through the cooperation between the handle, the fixed plate, the fifth spring, and the rotating shaft, drive the rotating plate to move relative to the fixed plate, so that the third protrusion provided on one side of the rotating plate slides out from the third groove provided in sequence on the fixed plate, and the restriction on the rotation of the rotating plate on the fixed plate is released. Then, turn the handle on the fixed plate to drive the rotating plate to rotate on the fixed plate, and contact with the second column through the vortex groove. The component force generated after the contact will drive the column to move, thereby driving the support rod to slide on the sleeve, and slightly change the position of the single spray pipe relative to the sleeve, ensuring that the spray pipe fully sprays the top of the expander, thereby improving the effect of lubricating the expander;

[0026] After the small adjustment is completed, the force applied to the handle is cancelled, so that the third protrusion on the turntable enters the corresponding third groove. The resistance generated by the contact between the two will limit the rotation of the turntable on the fixed plate, thereby preventing the external force from accidentally driving the turntable to rotate, resulting in the spray pipe being unable to fully spray the top of the expander, thereby improving the effect of lubricating the expander; in addition, after adjusting the position of a single spray pipe, the second column will be re-positioned above the flat groove. Since the force applied to the flat groove by the second column is perpendicular to the flat groove, the second column cannot push the turntable to rotate relative to each other, further preventing the turntable from rotating relative to the fixed plate, ensuring that the spray pipe fully sprays the top of the expander, and improving the effect of lubricating the expander.

[0051] Preferably, Figure 8 As shown, the support rod 5 is slidably arranged on the sleeve 2, and a turntable 46 is rotatably connected to the sleeve 2. The turntable 46 is provided with a plurality of vortex grooves 47, and a flat groove 48 is provided between two adjacent vortex grooves 47. A second column 49 is provided at the end of the support rod 5, and the second column 49 is in sliding contact with the vortex groove 47 and the flat groove 48 respectively. When it is necessary to slightly change the position of a single spray pipe 4 relative to the sleeve 2, the vortex groove 47 contacts the second column 49, and the component force generated after the contact will drive the column to move, thereby driving the support rod 5 to slide on the sleeve 2. , slightly change the position of the single spray pipe 4 relative to the sleeve 2 to ensure that the spray pipe 4 fully sprays the top of the expander 1, thereby improving the effect of lubricating the expander 1; after adjusting the position of the single spray pipe 4, the second column 49 will be re-located above the flat groove 48. Since the force applied to the flat groove 48 by the second column 49 is perpendicular to the flat groove 48, the second column 49 cannot push the turntable 46 to rotate relative to each other, further preventing the turntable 46 from rotating relative to the fixed plate 50, ensuring that the spray pipe 4 fully sprays the top of the expander 1, thereby improving the effect of lubricating the expander 1.

[0052] Preferably, Figure 8 and Fig. 9As shown, a fixed disk 50 is provided on the sleeve 2, and a rotating shaft 51 is provided on the rotating disk 46. After the rotating shaft 51 passes through the fixed disk 50, a handle 52 is provided. A fifth spring 53 is provided between the handle 52 and the fixed disk 50. A plurality of third grooves 54 are provided on the fixed disk 50, and third protrusions 55 that are plugged and matched with the third grooves 54 are symmetrically provided on the rotating disk 46. When it is necessary to slightly change the position of a single spray pipe 4 relative to the sleeve 2, the fifth spring 53 provided between the handle 52 and the fixed disk 50 is compressed by pressing the handle 52 provided on the corresponding spray pipe 4, and at the same time, the rotating disk 46 is driven to move relative to the fixed disk 50 through the rotating shaft 51, so that the third protrusion 55 provided on one side of the rotating disk 46 slides out from the third grooves 54 provided in sequence on the fixed disk 50, thereby releasing the rotating disk 46 from rotating on the fixed disk 50. The movement is restricted, and then the handle 52 is turned on the fixed plate 50 to drive the turntable 46 to rotate on the fixed plate 50, and contact the second column 49 through the vortex groove 47. The component force generated after the contact will drive the column to move, thereby driving the support rod 5 to slide on the sleeve 2, slightly changing the position of the single spray pipe 4 relative to the sleeve 2, ensuring that the spray pipe 4 fully sprays the top of the expander 1, thereby improving the effect of lubricating the expander 1; after the small adjustment is completed, the force applied to the handle 52 is canceled, so that the third protrusion 62 on the turntable 46 enters the corresponding third groove 54, and the resistance generated after the two contact will limit the rotation of the turntable 46 on the fixed plate 50, avoiding external force from accidentally driving the turntable 46 to rotate, resulting in the spray pipe 4 being unable to fully spray the top of the expander 1, thereby improving the effect of lubricating the expander 1.

[0053] Preferably, Fig. 9 and Fig.10 As shown, the fixed disk 50 is provided with a slide bar 56 slidably connected with the sleeve 2, and the end of the slide bar 56 is provided with a third column 57. The sleeve 2 is slidably connected with an arc plate 58, and the arc plate 58 is provided with a plurality of inclined grooves 59 that are in sliding contact with the third column 57. The arc plate 58 is in contact with the corresponding columns through the plurality of inclined grooves 59 provided on the arc plate 58, and the component force generated simultaneously drives the plurality of slide bars 56 to slide on the fixed disk 50, and transmits the component force through the fixed disk 50, the rotating shaft 51, the rotating disk 46 and the second column 49, driving the support rod 5 to slide on the sleeve 2, thereby simultaneously adjusting the positions of the plurality of spray pipes 4 on the same side on the sleeve 2, so that the atomizing head 6 provided at the end of the spray pipe 4 can fully spray the top of the expander 1, thereby improving the effect of lubricating the expander 1;

[0054] Preferably, Fig. 9 and Fig.10As shown, the sliding sleeve 35 is provided with a guide block 60 slidably connected to the arc plate 58, and the arc plate 58 is rotatably connected with a screw rod 61, and the end of the screw rod 61 is provided with a plurality of protrusions 62 in contact with the arc plate 58. When it is necessary to significantly change the positions of the plurality of spray pipes 4 relative to the sleeve 2, the screw rod 61 is loosened so that the plurality of protrusions 62 provided at the end of the screw rod 61 no longer contact with the arc plate 58, so that the arc plate 58 can slide smoothly on the sleeve 2; after adjusting the positions of the plurality of spray pipes 4, the screw rod 61 is tightened so that the plurality of protrusions 62 provided at the end of the screw rod 61 contact with the arc plate 58 again, and the friction force generated after the contact will limit the sliding of the arc plate 58 on the sleeve 2, thereby preventing the external force from accidentally pushing the arc plate 58, changing the position of the spray pipe 4 on the sleeve 2, affecting the effect of spraying the top of the expander 1, and further improving the effect of lubricating the expander 1.

[0055] Preferably, Figure 8 As shown, the spray pipe 4 is arc-shaped, and the curvature of the spray pipe 4 is equal to the upper side of the upper piece of the expander 1 and the lower side of the lower piece of the expander 1. The spray angle of the atomizer head 6 is adjusted so that the atomizer head 6 on the spray pipe 4 is perpendicular to the tangent of the outer side of the upper piece of the expander 1 and the lower piece of the expander 1, so that the lubricant sprayed by the atomizer head 6 is better wrapped on the outer side of the spray pipe 4, thereby improving the effect of the subsequent spray mechanism spraying the lubricant on the expander 1, thereby further improving the effect of lubricating the expander 1.

[0056] Example 1

[0057] The present invention provides a contact lubricant spraying device, such as Figure 1 , Figure 2 , Figure 3 and Figure 8 As shown, when the expander 1 needs to be lubricated, the upper piece and the lower piece of the expander 1 are simultaneously inserted into the opening of the sleeve 2, and the upper piece and the lower piece of the expander 1 are respectively in sliding contact with the upper piece and the lower piece of the expander 1 through the guide hole 3, and the upper piece and the lower piece of the expander 1 are respectively guided to prevent the expander 1 from deviating from the track, thereby improving the effect of the subsequent spraying mechanism spraying the lubricant on the expander 1;

[0058] The expander 1 is further extended into the sleeve 2 until the end of the upper plate of the expander 1 or the lower plate of the expander 1 contacts the push plate 17, and the driving block 14 is pushed to slide on the sleeve 2. Since the push block 15 and the driving arm 12 are not perpendicular to each other at the beginning, the force arm between the push block 15 and the driving arm 12 is prevented from being zero. At the same time, the sliding groove 16 provided on the push block 15 is in sliding contact with the first column 13 provided on the driving arm 12. The component force generated after the contact will push the driving arm 12 to rotate around the valve stem 11, and the torque is transmitted through the valve stem 11, driving the valve plate 10 to rotate on the valve body 9, thereby changing the opening and closing relationship of the valve, so that the lubricant can flow normally on the infusion pipeline 8, and in turn The plurality of inlets 7 respectively enter the spray pipes 4 provided on the upper and lower pieces of the dilator 1, and the plurality of atomizing heads 6 provided on the spray pipes 4 spray the surfaces of the upper and lower pieces of the dilator 1, respectively. Compared with the application of the paraffin oil lubricant cotton ball, the adhesion area of ​​the lubricant is greatly increased, the effect of lubricating the dilator 1 is improved, and the use of the same paraffin oil lubricant cotton ball to apply the tops of different dilators 1 is avoided, thereby reducing the risk of cross infection; at the same time, the lubricant can be refined by the atomizing head 6, so that the lubricant is fully sprayed on the upper and lower pieces of the dilator 1, further improving the effect of lubricating the dilator 1 and improving the patient's experience;

[0059] In addition, there is no need for an individual to hold a paraffin oil lubricant cotton ball to apply the top of the dilator 1. The dilator 1 can be sprayed by simply moving the dilator 1 and pressing the push plate 17, which simplifies the operation steps of lubricating the dilator 1 and improves the efficiency of lubricating the dilator 1.

[0060] After spraying for a period of time, the expander 1 is taken out, and the resilience generated by the compression of the first spring 18 drives the driving block 14 to reset, thereby achieving lubrication of the expander 1.

[0061] Example 2

[0062] On the basis of Example 1, Figure 3 , Figure 4 and Figure 5As shown, when the opening and closing angle of the valve needs to be adjusted, the fixed block 26 is pushed to the left and the resistance applied by the second spring 34 is overcome. The component force generated after the ball 32 contacts the groove 33 drives the ball 32 to slide inward, compressing the second spring 34, so that the fixed block 26 can slide relative to the adjusting block 25, until the second protrusion 31 provided on the L-shaped block 29 slides out of the second groove 30 provided on the fixed block 26, and the restriction of the fixed block 26 on the rotation of the adjusting block 25 is released. Then, the adjusting block 25 is rotated on the guide rod 24. Since the adjusting block 25 is threadedly connected with the screw 61, the adjusting block 25 slides on the screw 61, changing the restriction range of the driving block 14 sliding on the sleeve 2, thereby limiting the maximum opening angle of the valve plate 10, controlling the flow rate of the lubricant, and making the lubricant flow rate in a suitable range, so that the lubricant can be evenly dispersed into small droplets, so that the spray coverage is wider and more uniform, thereby improving the effect of the lubricating expander 1;

[0063] After adjusting the opening and closing angle of the valve, the fixing block 26 is pushed back to the right side to return to the starting position. At this time, the fixing block 26 contacts the adjusting block 25 again, and the second protrusion 31 provided on the L-shaped block 29 also re-enters the second groove 30 provided on the fixing block 26. The resistance generated by the contact between the second protrusion 31 and the second groove 30, and the resistance generated by the contact between the first protrusion 28 provided on the fixing block 26 and the first groove 27 provided on the guide rod 24, will limit the rotation of the adjusting block 25 on the guide rod 24, and cooperate with the adjusting block 2 The threaded connection between the guide rod 24 and the ball 32 will limit the sliding of the adjusting block 25 on the guide rod 24, so as to prevent the adjusting block 25 from being pushed to rotate by an external force accidentally, resulting in a change in the maximum opening angle of the valve, thereby improving the effect of the lubricating expander 1; at the same time, the ball 32 is reset under the action of the second rebound force, and the resistance generated by the contact between the ball 32 and the groove 33 will limit the sliding of the fixing block 26 relative to the adjusting block 25, so as to prevent the fixing block 26 from being pushed to move by an external force accidentally, resulting in a change in the maximum opening angle of the valve, thereby further improving the effect of the lubricating expander 1.

[0064] Example 3

[0065] On the basis of Example 2, Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, when lubricating expanders 1 of different sizes, it is necessary to adjust the initial position of the push plate 17 to ensure that the expander 1 can smoothly contact the push plate 17 and drive the valve to open, so that the infusion pipeline 8 can smoothly transport the lubricant to achieve lubrication of the expander 1; at the same time, it is also necessary to change the positions of several spray pipes 4 relative to the sleeve 2, so that the atomizing head 6 provided at the end of the spray pipe 4 can fully spray the top of the expander 1, thereby improving the effect of lubricating the expander 1.

[0066] When the initial position of the push plate 17 needs to be adjusted, the handle 37 is rotated by applying a force that overcomes the action of the fourth spring 45, and the conical surface 44 provided at the end of the fixing rod 42 contacts the limiting hole 43. The component force generated drives the fixing rod 42 to move toward both sides, so that the handle 37 can continue to rotate on the sliding sleeve 35 until the inclined surfaces 39 provided on the left and right sides of the limiting rod 38 contact the left and right sides of the notch 36 respectively, and then the sliding sleeve 35 is slid on the sleeve 2 relative to the driving block 14. The component force generated after the inclined surface 39 contacts the notch 36 drives the limiting rod 38 to move toward both sides, so that the sliding sleeve 35 can slide relative to the driving block 14, and the push plate 17 is driven to move to the required area, ensuring that the expander 1 can smoothly contact the push plate 17, and drive the valve to open, so that the infusion pipeline 8 can smoothly transport the lubricant, and the lubrication of the expander 1 is realized;

[0067] In addition, after the position of the push plate 17 is adjusted, the reset handle 37 is used to make the flat surfaces 40 provided on the front and rear sides of the limit rod 38 contact the groove 36. The resistance generated by the contact between the two will limit the further movement of the sleeve 35 relative to the drive block 14, thereby preventing external force from accidentally driving the sleeve 35 to move and changing the starting position of the push plate 17, resulting in the dilator 1 being unable to contact the push plate 17 smoothly, and the valve being unable to be fully opened, affecting the effect of the spray dilator 1, or the dilator 1 being in contact with the push plate 17 too early, and the entire top of the dilator 1 being unable to be inserted into the sleeve 2, resulting in some areas being unable to be lubricated; at the same time, the resistance generated by the contact between the conical surface 44 at the end of the fixing rod 42 and the limit hole 43 can prevent external force from accidentally pushing the handle 52 to move, thereby further improving the stability of the overall structure, thereby improving the effect of lubricating the dilator 1 and improving the patient's experience.

[0068] Example 4

[0069] On the basis of Example 2, Figure 8 , Fig. 9 and Fig.10As shown, when it is necessary to significantly change the positions of multiple spray pipes 4 relative to the sleeve 2, the screw 61 is loosened so that the multiple protrusions 62 provided at the end of the screw 61 no longer contact the arc plate 58, so that the arc plate 58 can slide smoothly on the sleeve 2, and contact with the corresponding columns through the multiple inclined grooves 59 provided on the arc plate 58. The component force generated simultaneously drives the multiple slide bars 56 to slide on the fixed plate 50, and transmits the component force through the fixed plate 50, the rotating shaft 51, the rotating plate 46 and the second column 49, driving the support rod 5 to slide on the sleeve 2, thereby adjusting the multiple positions on the same side at the same time. The positions of the spray pipes 4 on the sleeve 2 are such that the atomizing head 6 provided at the end of the spray pipes 4 can fully spray the top of the expander 1, thereby improving the lubrication effect of the expander 1; after adjusting the positions of the spray pipes 4, the screw 61 is tightened so that the plurality of protrusions 62 provided at the end of the screw 61 are in contact with the arc plate 58 again, and the friction force generated after the contact will limit the arc plate 58 from sliding on the sleeve 2, thereby preventing the arc plate 58 from being pushed inadvertently by external force, changing the position of the spray pipe 4 on the sleeve 2, and affecting the effect of spraying the top of the expander 1, thereby further improving the lubrication effect of the expander 1;

[0070] When it is necessary to slightly change the position of a single spray pipe 4 relative to the sleeve 2, the handle 52 provided on the corresponding spray pipe 4 is pressed to compress the fifth spring 53 provided between the handle 52 and the fixed disk 50, and at the same time, the rotating disk 46 is driven to move relative to the fixed disk 50 through the rotating shaft 51, so that the third protrusion 55 provided on one side of the rotating disk 46 slides out from the third groove 54 provided in sequence on the fixed disk 50, and the restriction on the rotation of the rotating disk 46 on the fixed disk 50 is released. Then, the handle 52 is rotated on the fixed disk 50 to drive the rotating disk 46 to rotate on the fixed disk 50 and contact the second column 49 through the vortex groove 47. The component force generated after the contact will drive the column to move, thereby driving the support rod 5 to slide on the sleeve 2, and slightly changing the position of the single spray pipe 4 relative to the sleeve 2, ensuring that the spray pipe 4 fully sprays the top of the expander 1, thereby improving the effect of lubricating the expander 1;

[0071] After the small adjustment is completed, the force applied to the handle 52 is cancelled, so that the third protrusion 62 on the turntable 46 enters the corresponding third groove 54. The resistance generated by the contact between the two will limit the rotation of the turntable 46 on the fixed plate 50, thereby preventing the external force from accidentally driving the turntable 46 to rotate, resulting in the spray pipe 4 being unable to fully spray the top of the expander 1, thereby improving the effect of lubricating the expander 1; in addition, after adjusting the position of a single spray pipe 4, the second column 49 will be re-located above the flat groove 48. Since the force applied to the flat groove 48 by the second column 49 is perpendicular to the flat groove 48, the second column 49 cannot push the turntable 46 to rotate relative to each other, further preventing the turntable 46 from rotating relative to the fixed plate 50, ensuring that the spray pipe 4 fully sprays the top of the expander 1, thereby improving the effect of lubricating the expander 1.
