Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a drainage and medicine application device for surgical wounds in pediatric surgery. Background Art

[0002] In pediatric surgery, the care of postoperative wounds is a crucial link. The physical functions of children are not yet fully developed, and their tolerance and healing ability to surgical wounds are relatively weak. Therefore, the treatment of postoperative wounds requires more precision and efficiency. The main purpose of surgical wound care is to prevent infection, promote healing, and minimize scar formation as much as possible to ensure the health and quality of life of children. Currently, in clinical practice, the treatment of surgical wounds in pediatric surgery usually adopts a step-by-step method, that is, first, the exudate in the wound is drained through a drainage tube, and then medicine is applied through dressings or manual application. However, this traditional treatment method has many problems and deficiencies.

[0003] The existing Chinese patent with the publication number CN220833729U includes an operating table, a partition board, a fixing block, a hook, a player, and a bell, etc. A partition board for separating medical staff and pediatric patients is connected to the operating table. A player is installed at the rear of the partition board. At least two bells for attracting the attention of pediatric patients are installed on the partition board. The upper part of the partition board is connected to a fixing block, and a hook is connected to the fixing block.

[0004] When the above device is in use, a first water pump can make the nozzle spray misty liquid medicine to clean and drain the surgical wound, and the collection box can collect waste liquid. However, in the actual use process, after cleaning and draining the surgical wound, some cleaning liquid and secretions will remain inside the wound, increasing the risk of infection. Therefore, it is difficult to drain and discharge the cleaning liquid and secretions remaining inside the wound.

[0005] Therefore, we propose a drainage and medicine application device for surgical wounds in pediatric surgery. Summary of the Invention

[0006] The purpose of the present invention is to provide a drainage and medicine application device for surgical wounds in pediatric surgery, which has the advantage of draining and discharging the cleaning liquid and secretions remaining inside the wound, and solves the problems in the background art.

[0007] To achieve the above object, the present invention provides the following technical solution: A wound drainage and medicine application device for pediatric surgery, including a processing box for supporting the limbs of children. On both sides of the processing box at symmetric positions, there are fixedly connected inclined panels. On the symmetric positions of the opposite surfaces of the two inclined panels, there are fixedly connected track rods. Inside the inner walls of the two track rods, a moving plate is horizontally movably connected. The moving plate is penetrated and rotatably connected with a drainage tube. The inner wall of one of the track rods is penetrated and fixedly rotationally connected with a threaded rod driven to rotate by a power mechanism, and the moving plate is penetrated by the threaded rod and is screwed thereon. On one side of the moving plate close to the drainage tube, there is a cleaning tube for cleaning the wound. On the inclined panel, there is a drainage mechanism for driving the drainage tube to suck and drain the cleaning liquid and secretions at the wound site and a squeezing mechanism for squeezing out the cleaning liquid and secretions inside the wound.

[0008] Preferably, the drainage mechanism includes inclined grooves opened on the opposite surfaces of the two inclined panels. Inside the inner walls of the two inclined grooves, there are reciprocatingly movably connected movable rods. The opposite ends of the two movable rods are fixedly connected with a cylindrical shell. The end of the drainage tube penetrates into the inner wall of the cylindrical shell and is fixedly connected with a piston plate, and the piston plate is in contact with and movably connected to the inner wall of the cylindrical shell.

[0009] Preferably, the squeezing mechanism includes support grooves opened at symmetric positions on the moving plate close to both ends. Inside the inner walls of the two support grooves, there are horizontally movably connected sleeve blocks. Inside the inner walls of the bottoms of the two sleeve blocks, there are vertically movably connected lifting blocks. On the opposite surfaces of the end of each lifting block and the inner wall of the sleeve block, there are fixedly connected springs for guiding the lifting block to move back and forth to reset. The bottoms of the two lifting blocks are fixedly connected with arc-shaped pressing plates for pressing the skin on both sides of the wound.

[0010] Preferably, a threaded sleeve for driving the drainage tube to reciprocate and rotate is fixedly connected to the inner wall of the bottom of the cylindrical shell, and an external thread tooth for screwing with the inner wall of the threaded sleeve is fixedly connected to the outer contour of the drainage tube. An oval block for pulling the two sleeve blocks to move back and forth in opposite or same directions is fixedly connected to the outer contour of the threaded rod close to the bottom of the threaded sleeve. On the opposite surfaces of the two sleeve blocks close to the ends, there are fixedly connected L-shaped blocks, and an oval groove for supporting the two L-shaped blocks on both sides is opened on the oval block.

[0011] Preferably, a cleaning mechanism for cleaning the wound is provided on the cleaning tube. The cleaning mechanism includes a liquid storage tank for storing cleaning liquid, which is vertically movably connected to the outer contour of the cleaning tube close to the end. The cleaning tube is penetrated and fixedly connected with a balloon for sucking the cleaning liquid inside the liquid storage tank and cleaning the wound, and a plurality of annularly arranged liquid passing holes are opened on the outer contour of the cleaning tube close to the end. The liquid storage tank and the support rods are fixedly rotationally connected at symmetric positions with the two sleeve blocks.

[0012] Preferably, L-shaped rods are fixedly connected to the sides of the two sleeve blocks close to the cleaning tube. Clamping plates for reciprocally squeezing the balloon are fixedly connected to the opposite ends of the two L-shaped rods. The ends of the two support rods away from the liquid storage tank are respectively rotatably connected to the adjacent L-shaped rod through a pin shaft.

[0013] Preferably, a medicine application mechanism for applying medicine to the wound of the child is provided on the moving plate. The medicine application mechanism includes an arc-shaped housing fixedly connected to the side of the moving plate away from the cleaning tube. The arc-shaped housing is penetrated and fixedly connected with a medicine storage tank. And a sieve plate for sieving the medicine powder and evenly sprinkling it on the wound is penetrated and fixedly connected at the corresponding position of the moving plate and the outlet end of the medicine storage tank.

[0014] Preferably, a crank is rotatably connected to the side of the moving plate close to the arc-shaped housing. One end of the crank close to the medicine storage tank is fixedly connected with an arc-shaped block that moves in an arc on the inner wall of the arc-shaped housing. And a medicine taking hole with the same diameter as the sieve plate is formed in the arc-shaped block. A torsion spring for guiding the crank to rotate back to its original position is fixedly connected to the opposite surfaces of the crank and the moving plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] First, through the cooperation of the inclined groove, the movable rod, the cylindrical housing and the piston plate, the reciprocating movement of the cylindrical housing and negative pressure drainage can be realized. When the cylindrical housing moves upward under the action of the inclined groove, the piston plate remains stationary, so that negative pressure is formed inside the cylindrical housing, enabling the drainage tube to suck the cleaning liquid and secretions at the wound through the drainage tube into the cylindrical housing, improving the drainage efficiency, avoiding the residual liquid inside the wound, significantly reducing the infection risk, and providing good conditions for the rapid healing of the wound.

[0017] Second, through the cooperation of the sleeve block, the lifting block, the spring and the arc-shaped pressing plate, the skin on both sides of the wound can be squeezed. During the drainage process, the arc-shaped pressing plate fits with the skin, and through the opposite movement of the sleeve blocks, the cleaning liquid and secretions inside the wound are squeezed out, further promoting the suction effect of the drainage tube, not only enhancing the cleaning effect inside the wound, but also assisting drainage by physical squeezing to ensure that the liquid inside the wound can be completely discharged, further reducing the possibility of infection.

[0018] Third, through the cooperation of the liquid storage tank, the balloon, the liquid through hole and the clamping plate, uniform cleaning of the wound can be realized. The cleaning liquid in the liquid storage tank enters the balloon through the liquid through hole, and the balloon squeezes the cleaning liquid out through the cleaning tube under the action of the clamping plate to clean the surface of the wound, ensuring that the cleaning liquid evenly covers the wound, and also realizing the suction of the cleaning liquid in the liquid storage tank through the reset of the balloon. The uniform cleaning effect helps to remove dirt and bacteria inside the wound and promotes the rapid healing of the wound.

[0019] IV. Through the cooperation of the arc-shaped housing, the medicine storage tank, the sieve plate, the crank and the arc-shaped block, the uniform distribution of the medicinal powder can be achieved. The medicinal powder in the medicine storage tank enters the sieve plate through the medicine taking holes of the arc-shaped block. After the sieve plate evenly screens the medicinal powder, it is sprinkled on the wound. This can not only ensure that the medicinal powder evenly covers the wound, but also avoid the caking of the medicinal powder through the action of the sieve plate, improve the utilization rate of the drug. The uniform medicine application effect helps the drug to play a better role, improve the treatment effect, and promote the rapid healing of the wound.

[0020] Through the combined use of the above structures, the problem that in the actual use process of the existing device, after cleaning and draining the surgical wound, some cleaning fluids and secretions will remain inside the wound, increasing the risk of infection, and thus it is difficult to drain and discharge the cleaning fluids and secretions remaining inside the wound is solved.

[0039] During use, through the inclined slots 201 formed on the inclined panel 2, and the movable rods 7 provided on the inclined slots 201, the inclined slots 201 can support the moving direction of the movable rods 7. And with the cylindrical shell 8 provided on the movable rods 7, the cylindrical shell 8 is fixedly supported on the movable rods 7. Through the piston plate 9 provided on the drainage tube 6, the drainage tube 6 can movably support the piston plate 9 on the inner wall of the cylindrical shell 8.

[0040] With the limbs of the child placed in the arc-shaped grooves at both ends of the processing box 1, and the drainage tube 6 located above the limb wound, when the moving plate 4 is driven by the threaded rod 5 to move horizontally in the D direction at this time, the cylindrical shell 8 can move synchronously with the moving plate 4, and the cylindrical shell 8 drives the movable rod 7 to move along the inner wall of the inclined groove 201, enabling the movable rod 7 to pull the cylindrical shell 8 to move in the upward vertical direction under the action of the inclined groove 201. And the piston plate 9 is in a static state, so the air pressure inside the cylindrical shell 8 near the end is in a negative pressure state. Thus, the bottom end of the drainage tube 6 can suck the cleaning liquid and secretions at the wound to the inner wall of the cylindrical shell 8, and the piston plate 9 is conical to prevent the cleaning liquid and secretions inside the cylindrical shell 8 from flowing back.

[0041] Embodiment Three:

[0042] On the basis of Embodiment Two, further:

[0043] The extrusion mechanism includes support grooves 401 symmetrically arranged near both ends of the moving plate 4. The inner walls of both ends of the support grooves 401 are horizontally movably connected with sleeve blocks 10. The inner walls of the bottoms of both sleeve blocks 10 are vertically movably connected with lifting blocks 11. On the opposite surfaces of the ends of each lifting block 11 and the inner wall of the sleeve block 10, springs 12 for guiding the reset movement of the lifting block 11 are fixedly connected. The bottoms of both ends of the lifting blocks 11 are fixedly connected with arc-shaped pressing plates 13 for pressing the skin on both sides of the wound.

[0044] The inner wall of the bottom end of the cylindrical shell 8 is fixedly connected with a threaded sleeve 14 for driving the drainage tube 6 to rotate reciprocally, and an external thread tooth 601 for screwing with the inner wall of the threaded sleeve 14 is fixedly connected to the outer contour of the drainage tube 6.

L-shaped blocks 16 are fixedly connected to the opposite surfaces near the ends of both sleeve blocks 10, and an oval groove 151 for supporting the two L-shaped blocks 16 is formed on the oval block 15.

[0045] During use, through the support grooves 401 formed on the moving plate 4 and the sleeve blocks 10 arranged on the support grooves 401, the sleeve blocks 10 can move horizontally on the inner walls of the support grooves 401. And the lifting blocks 11 arranged on the sleeve blocks 10 and the arc-shaped pressing plates 13 arranged on the lifting blocks 11. First, the arc-shaped pressing plates 13 are fixedly supported on the lifting blocks 11, then the lifting blocks 11 can drive the arc-shaped pressing plates 13 to move vertically and movably on the inner walls of the sleeve blocks 10. Through the springs 12 arranged on the lifting blocks 11, and the springs 12 support the lifting blocks 11, thus the lifting blocks 11 can push the arc-shaped pressing plates 13 to fit with the skin on both sides of the patient's limb and the wound under the elastic force of the springs 12.

Through the L-shaped block 16 provided on the sleeve block 10 and the oval groove 151 opened on the oval block 15, the end of the L-shaped block 16 can be movably supported on the inner wall by the oval groove 151. Along with the rotation of the oval block 15, thus the L-shaped block 16 can pull the two sleeve blocks 10 to move reciprocally towards or away from each other under the action of the oval groove 151. And the arc-shaped pressing plate 13 is attached to the skin on both sides of the limb. Furthermore, the sleeve block 10 can drive the arc-shaped pressing plate 13 to move towards each other to squeeze out the cleaning liquid and secretions inside the wound. Then the drainage tube 6 can suck and drain the cleaning liquid and secretions squeezed out from the wound inside the cylindrical shell 8, further improving the cleaning and drainage effect of the wound.

[0047] Embodiment 4:

[0048] On the basis of Embodiment 3, further:

[0049] A cleaning mechanism for cleaning the wound is provided on the cleaning tube 17. The cleaning mechanism includes a liquid storage tank 19 for storing cleaning liquid, which is connected to move up and down on the outer contour of the cleaning tube 17 near the end. The cleaning tube 17 is penetrated and fixedly connected with a balloon 18 for sucking the cleaning liquid inside the liquid storage tank 19 and cleaning the wound. And a plurality of annularly arranged liquid through holes 171 are opened on the outer contour of the cleaning tube 17 near the end. The liquid storage tank 19 and the support rods 22 are rotatably connected on the fixed axis at the symmetric positions of the two sleeve blocks 10.

[0050] On one side of the two sleeve blocks 10 close to the cleaning tube 17, L-shaped rods 20 are fixedly connected respectively. On the relative ends of the two L-shaped rods 20, clamping plates 21 for reciprocally squeezing the balloon 18 are fixedly connected respectively. One end of each of the two support rods 22 far away from the liquid storage tank 19 is rotatably connected to the adjacent side L-shaped rod 20 through a pin shaft.

[0051] During use, through the liquid storage tank 19 arranged on the cleaning tube 17, the liquid storage tank 19 is connected in a lifting and moving manner on the outer contour of the cleaning tube 17. Moreover, the balloon 18 arranged on the cleaning tube 17 can connect the balloon 18 with the inner walls of the cleaning tube 17 and the liquid storage tank 19. Through the L-shaped rod 20 arranged on the sleeve block 10, and the L-shaped rod 20 is fixedly supported on the sleeve block 10, the L-shaped rod 20 can move reciprocally towards or away synchronously with the sleeve block 10. Through the support rod 22 arranged on the liquid storage tank 19, both ends of the support rod 22 are rotatably supported on the liquid storage tank 19 and the L-shaped rod 20 respectively. Along with the L-shaped rod 20 moving reciprocally towards or away, thus the support rod 22 can push 029 to move reciprocally up and down on the cleaning tube 17.

[0052] First, store the cleaning liquid inside the liquid storage tank 19. As Figure 2 , Figure 3 , Figure 5 and Figure 7 shown, the sleeve block 10 drives the L-shaped rod 20 to move away to the limit position. And for the liquid through hole 171 opened on the cleaning tube 17, the support rod 22 pulls the liquid storage tank 19 to move downward under the action of the L-shaped rod 20. At this time, the liquid through hole 171 contacts the cleaning liquid inside the liquid storage tank 19, so that the cleaning liquid inside the liquid storage tank 19 enters the inside of the balloon 18 through the liquid through hole 171. Moreover, the clamping plate 21 arranged on the L-shaped rod 20, along with the sleeve block 10 driving the L-shaped rod 20 to move towards each other, makes the support rod 22 push the liquid storage tank 19 to move upward under the action of the L-shaped rod 20. And the liquid through hole 171 fits with the inner wall at the bottom end of the liquid storage tank 19, then the liquid through hole 171 is in a sealed state. At this time, the L-shaped rod 20 drives the clamping plate 21 to move towards each other to contact and squeeze the balloon 18, and the inner wall of the balloon 18 is in a positive pressure state under the extrusion of the clamping plate 21. Thus, the cleaning liquid inside the balloon 18 can be discharged through the bottom end of the cleaning tube 17 to clean the wound. At the same time, the cleaning liquid overflowing from the wound will fall into the inside of the treatment box 1 for collection.

[0053] Embodiment Five:

[0054] On the basis of Embodiment Four, furthermore:

[0055] An upper medicine mechanism for applying medicine to the wound of the child is arranged on the moving plate 4. The upper medicine mechanism includes that a curved shell 23 is fixedly connected to the side of the moving plate 4 away from the cleaning tube 17. The curved shell 23 is penetrated and fixedly connected with a medicine storage tank 24. And at the corresponding position between the moving plate 4 and the outlet end of the medicine storage tank 24, a sieve plate 25 that sieves the medicine powder and evenly sprinkles it on the wound is penetrated and fixedly connected.

[0056] One side of the moving plate 4 close to the arc-shaped housing 23 is rotatably connected to a crank 26 by a fixed axis. One end of the crank 26 close to the medicine storage tank 24 is fixedly connected to an arc-shaped block 27 that moves in an arc on the inner wall of the arc-shaped housing 23. A medicine-taking hole 271 with the same caliber as the sieve plate 25 is formed in the arc-shaped block 27. A torsion spring 28 for guiding the crank 26 to rotate back to its original position is fixedly connected to the opposite surfaces of the crank 26 and the moving plate 4.

[0057] During use, the arc-shaped housing 23 is fixedly supported on the moving plate 4 through the arc-shaped housing 23 provided on the moving plate 4. Through the medicine storage tank 24 provided on the arc-shaped housing 23 and the sieve plate 25 provided on the moving plate 4, the sieve plate 25 and the discharge port at the bottom of the medicine storage tank 24 are in corresponding positions. Through the crank 26 provided on the moving plate 4, the crank 26 can be rotatably connected to the moving plate 4 by a fixed axis. Through the arc-shaped block 27 provided on the crank 26, the arc-shaped block 27 can be fixedly supported on the crank 26. At the same time, the arc-shaped block 27 is connected to move in an arc on the inner wall of the arc-shaped housing 23. Through the torsion spring 28 provided on the crank 26, the torsion spring 28 can support the positions of the crank 26 and the arc-shaped block 27. Through the medicine-taking hole 271 formed in the arc-shaped block 27, the medicine-taking hole 271 is adapted to the apertures of the sieve plate 25 and the discharge port of the medicine storage tank 24.

[0058] When both ends of the elliptical block 15 rotate and contact the end of the crank 26 far from the arc-shaped block 27, the crank 26 rotates under the push of the elliptical block 15 and drives the arc-shaped block 27 to move in an arc on the inner wall of the arc-shaped housing 23. At the same time, the arc-shaped block 27 drives the medicine-taking hole 271 to be disengaged from the positions of the medicine storage tank 24 and the sieve plate 25, and the torsion spring 28 rotates and contracts under the action of the crank 26. When the elliptical block 15 rotates and disengages from the crank 26, at this time, the crank 26 can drive the arc-shaped block 27 to move in an arc and reset on the inner wall of the arc-shaped housing 23 under the elastic force of the torsion spring 28, and the arc-shaped block 27 drives the medicine-taking hole 271 to move in an arc to the corresponding position of the medicine storage tank 24 and the sieve plate 25. Then the medicine powder inside the medicine storage tank 24 can fall onto the inner wall of the medicine-taking hole 271 and be evenly screened through the sieve plate 25 to the wound. Along with the arc-shaped block 27 moving in an arc back and forth on the inner wall of the arc-shaped housing 23, the medicine powder is evenly sprinkled on the cleaned wound.

[0059] Furthermore, it is realized that during the actual use of the existing device, the residual cleaning liquid and secretions inside the wound can be drained and discharged, which is convenient to use and better than traditional products.
