Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a negative pressure suction device for neonatal umbilical sinus tracts. Background Art

[0002] As a congenital developmental anomaly of the neonatal umbilicus or a pathological structure caused by factors such as infection in the acquired stage, the neonatal umbilical sinus tract has a non-negligible impact on the health of neonates. It is manifested as a blind tube that does not communicate with the internal hollow organs in the neonatal umbilicus and opens on the umbilical skin. During embryonic development, incomplete closure of the vitelline duct or urachus often leaves such sinus tracts; in the acquired stage, when the umbilicus is infected and invaded by inflammation, destroying local tissues, it may also gradually lead to its formation.

[0003] In appearance, the umbilical sinus tract appears as a small hole from which secretions such as mucus and exudate often flow out, and the surrounding skin often shows a state of redness, swelling and dampness. Since the neonatal own immune system is not yet perfect, if the umbilical sinus tract is not treated in a timely and effective manner, it is extremely easy to cause infection, and umbilical inflammation is one of the common complications. In severe cases, it may even spread to the whole body, causing systemic infection and endangering the life and health of neonates.

[0004] Currently, in the treatment of neonatal umbilical sinus tracts, negative pressure drainage devices are commonly used auxiliary means. However, the existing negative pressure drainage devices have many drawbacks. In the actual use process, the functions of such devices are relatively single, and they can only achieve negative pressure drainage. When it is necessary to irrigate the sinus tract, medical staff have to replace the connector of the drainage tube and reconnect the irrigation device. This operation process is cumbersome and complex, not only consuming time and energy, but also increasing the risk of operation errors. More importantly, both irrigation and drainage after irrigation rely on the same pipeline, which is extremely easy to cause impurities, bacteria, etc. remaining inside the pipeline to re-enter the sinus tract during irrigation, contaminating the irrigation fluid and affecting the treatment effect. If the pipeline is frequently replaced to avoid contamination, it will not only significantly increase the work intensity of medical staff, reduce the cleaning efficiency, but also cause secondary trauma to the already fragile neonates, undoubtedly aggravating the pain of the children. Summary of the Invention

[0017] The technical solution provided by the present invention has at least the following beneficial effects compared with the prior art:

[0018] In the above solution, through the negative pressure suction mechanism, the present device can achieve efficient drainage of the neonatal umbilical sinus tract. During use, first fix the adhesive tape to the umbilicus of the child and insert the injection drainage tube. During drainage, pull the piston rod to move the piston plate outwards. Under the action of the one-way valve, negative pressure is generated in the negative pressure tube, the drainage bottle and the suction tube. The suction conduit is communicated with the injection drainage cavity, and the sinus tract tissue fluid is sucked into the drainage bottle. After the drainage is completed, release the piston rod. The telescopic spring drives the piston plate to move inwards. The first one-way valve is closed, and the second one-way valve exhausts. Repeatedly pulling the piston rod can continue the drainage. The tissue fluid condition can be monitored through the observation window during the process. After the drainage is completed, twist the threaded cap to remove the drainage bottle to collect the tissue fluid. This mechanism utilizes the design of the telescopic spring and the piston plate to achieve rapid and continuous drainage, reduce the risk of infection, and facilitate subsequent cleaning and maintenance.

[0019] The device is provided with a cleaning liquid supply mechanism, so that it can provide reliable guarantee for sinus cleaning and disinfection during use. When cleaning is required, the regulating valve is opened to add the cleaning liquid into the hopper, and the cleaning liquid enters the tank body through the guide, and the driving motor is started to make the rotating shaft rotate in the reverse direction, driving the stirring plate to stir and mix the medicine and the liquid medicine. At the same time, the reverse rotating auger makes the liquid medicine tumble to enhance the mixing effect. After the stirring is completed, the flow valve is opened, and the driving motor drives the auger to rotate in the forward direction. The liquid medicine enters the sinus tract through the drain pipe, the cleaning catheter, and the injection cleaning cavity to flush the medicine. The flow valve can be adjusted to control the flow rate during flushing to avoid irritating the sinus tract of the child. The mechanism uses an independent cavity to transport the liquid medicine and drain the tissue fluid to avoid liquid medicine contamination. There is no need to frequently change the tube, and the liquid medicine can be sucked in real time to achieve thorough cleaning and suction, effectively care for the sinus tract, and reduce the possibility of bacterial infection.

[0020] By providing an elastic connector, the convenience of disassembly and assembly of the cleaning liquid supply mechanism and the negative pressure suction mechanism can be greatly improved. When disassembly and assembly is required, the adjusting armrest is adjusted and pushed to drive the connecting shaft to rotate, so that the connecting rod rotates in a ring shape, and the arc-shaped rod is driven to disengage from the limiting hole, and the plug connector can be pulled out, the threaded cover and the drainage bottle can be removed, and the negative pressure suction mechanism and the negative pressure assembly can be quickly disassembled. During installation, the plug connector is inserted, and the adjusting armrest is pushed to move the arc-shaped rod outward and stably insert it into the sleeve connector. At this time, the torsion spring is compressed, and the adjusting armrest is released after the installation is completed. The torsion spring is reset to drive the arc-shaped rod to insert into the limiting hole, thereby realizing a stable connection between the sleeve connector and the plug connector. This design makes the device easy to quickly disassemble and clean, and further improves the convenience of caring for children. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] As Figures 1 to 8As shown in the figure, an embodiment of the present invention provides a negative pressure suction device for neonatal umbilical sinus, including an adhesive tape 1. The adhesive tape 1 is arranged in a disc shape. A hydrocolloid adhesive ring 11 is fixedly connected to the bottom of the adhesive tape 1. An injection and drainage catheter is fixedly installed in the middle of the adhesive tape 1. An injection and cleaning channel 4 and a negative pressure drainage channel are respectively formed on both sides inside the injection and drainage catheter. The top of the injection and drainage catheter passes through the adhesive tape 1 and is fixedly connected to a connector 10. A cleaning catheter 7 and a suction catheter 8 are respectively fixedly connected to both sides of the top of the connector 10. The output end of the cleaning catheter 7 is communicated with the injection and cleaning channel 4. The output end of the suction catheter 8 is communicated with the negative pressure drainage channel. Elastic connectors 9 are fixedly installed on the outer ends of the cleaning catheter 7 and the outer side of the suction catheter 8. The input end of the cleaning catheter 7 is fixedly connected to the inside of a cleaning liquid supply mechanism 6 through the elastic connector 9. The outer end of the suction catheter 8 is fixedly installed with a negative pressure suction mechanism 2 through the elastic connector 9.

[0049] During use, first, the disc-shaped adhesive tape 1 is attached and fixed to the neonatal umbilicus through the hydrocolloid adhesive ring 11 at the bottom. When sinus cleaning is required, the cleaning liquid in the cleaning liquid supply mechanism 6 enters the cleaning catheter 7 through the elastic connector 9, and then flows into the sinus through the connected injection and cleaning channel 4 to achieve the flushing of the sinus. When it is necessary to drain tissue fluid and the like in the sinus, the negative pressure suction mechanism 2 is activated to generate negative pressure, which is transmitted to the suction catheter 8 through the elastic connector 9, and then acts on the negative pressure drainage channel communicated therewith, sucking the liquid in the sinus through the injection and drainage catheter, the negative pressure drainage channel and the suction catheter 8 into the negative pressure suction mechanism 2 to complete the drainage operation. The whole device utilizes different channels and connection mechanisms to respectively achieve the functions of cleaning and negative pressure suction of the sinus.

[0050] As Figures 1 to 5As shown, the negative pressure suction mechanism 2 includes a negative pressure assembly 21. An elastic connector 9 is also fixedly connected to the outer end of the negative pressure assembly 21. The outer end of the elastic connector 9 on the negative pressure assembly 21 is fixedly connected to a negative pressure tube 22. A threaded cover 23 is fixedly installed at the bottom of the negative pressure tube 22. A drainage bottle 24 is threadedly connected to the bottom of the threaded cover 23. The other side of the top of the threaded cover 23 is fixedly connected to a suction tube 25. The outer end of the suction tube 25 is connected to the elastic connector 9 at the outer end of the suction guide tube 8. The negative pressure assembly 21 includes a negative pressure sleeve 211. A telescopic spring 212 is fixedly installed inside the negative pressure sleeve 211. The outer end of the telescopic spring 212 is fixedly connected to a piston plate 213. A piston rod 216 is fixedly connected to the outside of the piston plate 213. A first one-way valve 214 is fixedly connected to the inner end of the negative pressure sleeve 211. A second one-way valve 215 is fixedly connected to the top of the negative pressure sleeve 211 near the first one-way valve 214. The end of the first one-way valve 214 is connected to the elastic connector 9 on the negative pressure suction mechanism 2. Observation windows 26 are provided on both sides of the drainage bottle 24. An adjustment knob handle 27 is fixedly installed at the top of the drainage bottle 24. Anti-slip arc grooves 28 are arranged at equal intervals in a circular pattern on the outer surface of the adjustment knob handle 27.

[0051] When using the negative pressure suction mechanism 2, first connect the negative pressure tube 22 to the negative pressure assembly 21 through the elastic connector 9, and at the same time connect the suction tube 25 and the suction guide tube 8 using the elastic connector 9 to ensure that the entire system is connected. When drainage is required, pull the piston rod 216 to drive the piston plate 213 to move outwards, stretching the telescopic spring 212. At this time, the first one-way valve 214 is opened under the pressure formed by the piston plate 213, causing the negative pressure tube 22, the drainage bottle 24, and the suction tube 25 to generate negative pressure. Since the suction tube 25 is connected to the suction guide tube 8, the negative pressure drainage cavity is thus made to generate negative pressure, sucking the tissue fluid in the sinus tract into the drainage bottle 24 through the injection drainage catheter, the negative pressure drainage cavity, and the suction tube 25. After the drainage is completed, release the piston rod 216, and the telescopic spring 212 returns to its original position, driving the piston plate 213 to move inwards. The first one-way valve 214 closes to prevent gas from re-entering the sinus tract, and the second one-way valve 215 opens to exhaust the excess gas that has been drawn out. After the exhaust is completed, pull and push the piston rod 216 again to continue the drainage operation. During the drainage process, the situation of the tissue fluid in the drainage bottle 24 can be monitored in real time through the observation window 26, and the anti-slip arc grooves 28 on the adjustment knob handle 27 facilitate gripping during operation, making it convenient for the user to twist the threaded cover 23, thereby realizing the disassembly and installation of the drainage bottle 24 and facilitating the collection of the drained tissue fluid.

[0052] As Figures 1 to 3 and Figures 6 to 7As shown in the figure, the cleaning liquid supply mechanism 6 includes a tank body 61. A drain pipe 62 is fixedly connected to the bottom of the tank body 61. A connecting hose 63 is fixedly connected to the bottom of the drain pipe 62. The outer end of the connecting hose 63 is connected to an elastic connector 9 located on a cleaning conduit 7. A stirring assembly 64 is movably installed inside the tank body 61. The stirring assembly 64 includes a top cover 641 and mounting holes 642. The top cover 641 covers the top of the tank body 61. The mounting holes 642 are arranged in an equidistant circular pattern and opened at the upper end of the outer surface of the tank body 61. Fixing plates 643 are fixedly connected to the bottom of the top cover 641 in an equidistant circular pattern. A hand-twist screw 644 is threadedly connected to the lower end of the fixing plate 643. The end of the hand-twist screw 644 penetrates through the fixing plate 643 and is inserted into the inside of the mounting hole 642. A driving motor 645 is fixedly connected to the top of the top cover 641. The output end of the driving motor 645 penetrates through the top cover 641 and is fixedly connected to a rotating shaft 646. Stirring plates 647 are fixedly connected to the outer surface of the rotating shaft 646 at equal intervals. An auger 648 is fixedly connected to the lower end of the outer surface of the rotating shaft 646. The auger 648 is rotatably connected to the inside of the drain pipe 62. A regulating valve 649 is fixedly connected to one side of the top of the top cover 641. The bottom of the regulating valve 649 penetrates through the top cover 641 and is in communication with the inside of the tank body 61. A feeding hopper 650 is fixedly connected to the top of the regulating valve 649. The cleaning liquid supply mechanism 6 further includes a flow valve 651. The flow valve 651 is fixedly installed at the outer end of the cleaning conduit 7.

[0053] When using the cleaning liquid supply mechanism 6, first pour the cleaning liquid through the feeding hopper 650 at the top of the regulating valve 649. The regulating valve 649 can control the flow rate of the cleaning liquid entering the tank body 61. After the cleaning liquid enters the tank body 61 through the regulating valve 649, start the driving motor 645. The output end of the motor drives the rotating shaft 646 to rotate. The stirring plates 647 on the outer surface of the rotating shaft 646 rotate accordingly, stirring and mixing the medicine and the cleaning liquid in the tank body 61. At the same time, the auger 648 at the lower end of the rotating shaft 646 also rotates. When the rotating shaft 646 rotates reversely, the auger 648 makes the liquid medicine roll from bottom to top, cooperating with the agitation of the stirring plates 647 to enhance the mixing effect. After stirring is completed, open the flow valve 651. At this time, the driving motor 645 drives the auger 648 to rotate forward, and the mixed liquid medicine flows from the tank body 61 through the drain pipe 62, the connecting hose 63, and through the elastic connector 9 into the cleaning conduit 7, and finally enters the neonatal umbilical sinus through the injection cleaning channel 4 for flushing and applying medicine. During the process, the flow rate of the liquid medicine in the injection cleaning channel 4 can be controlled by adjusting the flow valve 651 to achieve the best cleaning effect and avoid causing discomfort and irritation to the child's sinus.

[0054] As Figures 1 to 8As shown, each of the elastic connectors 9 includes three socket joints 91 and three plug joints 92. The socket joints 91 are respectively installed at the outer ends of the cleaning conduit 7, the suction conduit 8, and the outer end of the first one-way valve 214. The plug joints 92 are respectively installed at the outer ends of the suction tube 25, the connecting hose 63, and the negative pressure tube 22. Elastic components 93 are provided at both ends of the plug joint 92. The plug joints 92 are inserted into the interior of the socket joints 91. The elastic component 93 includes a housing 931 and a limiting hole 932. The housing 931 is fixedly connected to both sides of the plug joint 92. A torsion spring 933 is fixedly connected inside the housing 931. A turntable 934 is fixedly installed inside the torsion spring 933. The turntable 934 is rotatably connected to the middle of the housing 931. A connecting rod 935 is fixedly connected to the outside of the turntable 934. An arc-shaped notch is provided in the middle of the housing 931. The connecting rod 935 is located inside the arc-shaped notch and extends outside the housing 931. An arc-shaped rod 936 is fixedly connected to the outer end of the connecting rod 935. The limiting holes 932 are respectively opened on both sides of the socket joint 91. The arc-shaped rod 936 is inserted into the interior of the limiting hole 932. The limiting hole 932 is arranged in a circular arc shape. The arc-shaped rod 936, the limiting hole 932, the torsion spring 933, and the turntable 934 are concentrically arranged. Both sides of the turntable 934 are fixedly connected with a connecting shaft 937. The outer end of the connecting shaft 937 passes through the housing 931 and is fixedly connected with an adjusting handle 938. The connecting shaft 937 is rotatably connected to the housing 931. The elastic connector 9 is used to connect the cleaning conduit 7, the suction conduit 8, the first one-way valve 214 with the suction tube 25, the connecting hose 63, and the negative pressure tube 22. Its core components are the socket joint 91 and the plug joint 92. Elastic components 93 are provided at both ends of the plug joint 92, and the connection is achieved by inserting the plug joint 92 into the socket joint 91.

[0055] When disassembly is required, push the adjusting handle 938 to drive the connecting shaft 937 to rotate, and then drive the turntable 934 to rotate, compressing the torsion spring 933, so that the connecting rod 935 drives the arc-shaped rod 936 to disengage from the circular arc-shaped limiting holes 932 on both sides of the socket joint 91. At this time, the plug joint 92 can be easily pulled out of the socket joint 91 to complete the separation of the components; during installation, align the plug joint 92 with the socket joint 91 and insert it. Push the adjusting handle 938 to make the connecting shaft 937 drive the turntable 934 to rotate, and the connecting rod 935 pushes the arc-shaped rod 936 to move outward. When the plug joint 92 is in place, release the adjusting handle 938, and the torsion spring 933 resets, driving the turntable 934 to rotate in the reverse direction, so that the arc-shaped rod 936 is inserted into the limiting hole 932. Using the concentric structure of the arc-shaped rod 936 and the limiting hole 932, accurate and stable positioning is completed to ensure the firm connection between the socket joint 91 and the plug joint 92, and rapid and reliable disassembly and assembly between each pipeline are realized.

[0056] The working process of the technical solution provided by the present invention is as follows:

[0057] During use, first fix the adhesive tape 1 to the umbilicus of the child. At the same time, accurately insert the injection drainage tube 3 into the internal sinus tract. When drainage is required, pull the piston rod 216, driving the piston plate 213 to move outward. Due to the effect of the one-way valve, the first one-way valve 214 forms negative pressure in the pressure generated by the piston plate 213, causing negative pressure in the negative pressure tube 22, the drainage bottle 24, and the suction tube 25. At this time, the suction catheter 8 is in communication with the inside of the injection drainage cavity 5. Using the negative pressure suction of the injection drainage cavity 5 and the suction catheter 8, the tissue fluid in the sinus tract is sucked into the drainage bottle 24. After the drainage is completed, release the piston rod 216, and the telescopic spring 212 resets, driving the piston plate 213 to move inward. During this process, the first one-way valve 214 closes, and the second one-way valve 215 exhausts, discharging the excess extracted gas. After the exhaust is completed, pull the piston rod 216 again to continue the drainage operation. During the drainage process, the situation of the tissue fluid in the drainage bottle 24 can be monitored in real time through the observation window 26. After the drainage is completed, twist the threaded cap 23 to separate the drainage bottle 24 from the threaded cap 23, so as to conveniently remove the drainage bottle 24 and collect the drained tissue fluid. The negative pressure suction mechanism 2 adopts the design of the telescopic spring 212 and the piston plate 213, realizing the rapid and continuous suction and drainage of tissue fluid, effectively reducing the risk of infection, providing convenience for the suction treatment of sinus tract tissue fluid, and facilitating subsequent cleaning and maintenance.

[0058] The setting of the cleaning liquid supply mechanism 6 provides a reliable guarantee for the cleaning and disinfection of the sinus tract. When cleaning is required, open the regulating valve 649, add the cleaning liquid to the feeding hopper 650. The cleaning liquid is guided by the feeding hopper 650 and the regulating valve 649 and enters the inside of the tank body 61. Start the driving motor 645. The driving motor 645 drives the rotating shaft 646 to rotate reversely, and then drives the stirring plate 647 to rotate, stirring and mixing the medicine and the liquid medicine in the tank body 61. At the same time, the reversely rotating rotating shaft 646 drives the auger 648 to rotate reversely, causing the liquid medicine to roll from bottom to top, cooperating with the stirring action of the stirring plate 647 to enhance the mixing effect. After the stirring is completed, open the flow valve 651, start the driving motor 645 to drive the auger 648 to rotate forward, and convey the liquid medicine from top to bottom, so that it stably flows into the cleaning catheter 7 through the drain pipe 62, and then enters the internal sinus tract of the child through the injection cleaning cavity 4 to realize the flushing and medicine application of the sinus tract. During the flushing process, the flow rate of the liquid medicine in the injection cleaning cavity 4 can be precisely controlled by adjusting the flow valve 651 to avoid causing discomfort and irritation to the child's sinus tract due to too fast flow rate. During the use of the cleaning liquid supply mechanism 6, the conveying of the cleaning liquid and the suction and drainage of the tissue fluid adopt independent channels, effectively avoiding the problem of liquid medicine pollution caused by sharing a channel, and there is no need to frequently replace the catheter. During the flushing process, the liquid medicine can be sucked in real time, realizing a more thorough cleaning and suction function, playing a good nursing role for the sinus tract, and minimizing the possibility of sinus tract germ infection.

[0059] The provision of the elastic connector 9 greatly improves the convenience of disassembling and assembling the cleaning liquid supply mechanism 6 and the negative pressure suction mechanism 2. When it is necessary to disassemble and replace these two mechanisms, adjust the push-adjustable handrail 938 to drive the coupling shaft 937 to rotate, and then drive the connecting rod 935 to rotate. The connecting rod 935 rotates in a circular shape, driving the arc-shaped rod 936 at its outer end to rotate, so that the arc-shaped rod 936 disengages from the limit hole 932. At this time, the plug connector 92 can be pulled out from the inside of the socket connector 91, so as to conveniently remove the threaded cap 23 and the drainage bottle 24 from the outer end of the suction catheter 8, realizing the rapid disassembly of the negative pressure suction mechanism 2. At the same time, the negative pressure assembly 21 can also be quickly removed. During installation, insert the plug connector 92 into the inside of the socket connector 91, push the adjustable handrail 938 to drive the coupling shaft 937 and the turntable 934 to rotate, so that the connecting rod 935 and the arc-shaped rod 936 at its end move outwards, and insert the plug connector 92 stably into the socket connector 91. During the process of pushing the adjustable handrail 938, the torsion spring 933 is in a compressed state. After the installation is completed, release the adjustable handrail 938, and the torsion spring 933 resets, driving the turntable 934 to rotate, so that the connecting rod 935 drives the arc-shaped rod 936 to insert into the limit hole 932. Through the mutual engagement of the arc-shaped rod 936 and the limit hole 932, the stable connection between the socket connector 91 and the plug connector 92 is realized. This design makes the device convenient for rapid disassembly, cleaning and further improves the convenience of caring for children.
