Technical Field
[0001] The present invention belongs to the technical field of debridement and irrigation, and relates to an irrigation system for infected wounds. Background Art
[0002] Irrigation of infected wounds is an important part of treating infections and promoting healing. By irrigating infected wounds, bacteria and necrotic tissues can be removed, which helps to reduce the inflammatory response, reduce the risk of infection, prevent the spread of infection, and is beneficial to the growth of granulation tissue and the migration of epithelial cells, thus accelerating the wound healing process.
[0003] When irrigating the infected wounds of patients, it often causes discomfort such as pain. In order to prevent the patient from moving during wound irrigation, it is necessary to fix the patient's limbs. However, the irrigation time of the wound sometimes needs to be relatively long, and long-term fixation will affect the blood circulation of the patient's limbs and cause new discomfort.
[0004] To solve the above problems, the present invention proposes an irrigation system for infected wounds. Summary of the Invention

The sliding rod is elastically and slidably connected to the placement board; the irrigation unit is communicated with the output end of the double-screw pump. A plurality of liquid inlet holes communicating with the irrigation tank are opened on the double-screw pump. A throttling throat is provided in the middle of the liquid inlet hole. A channel communicating with the throttling throat is opened in the double-screw pump. A piston is hermetically and slidably connected in the channel. The plurality of liquid inlet holes correspond to the plurality of restraint straps one by one. The piston and the corresponding sliding rod are connected by a connecting member; the liquid inlet hole is arranged in cooperation with the blade of the screw conveyor in the double-screw pump; as the screw conveyor rotates, the plurality of liquid inlet holes are alternately communicated with the double-screw pump. According to the Venturi effect, the liquid inlet hole communicating with the double-screw pump generates an adsorption force at the throttling throat, thereby moving the corresponding piston. The piston pulls the sliding rod to move through the connecting member, so that the corresponding restraint strap is tightened, and thus the plurality of restraint straps are alternately tightened; the double-screw pump transports the irrigation liquid into the irrigation unit to irrigate the patient's wound.
[0007] Further, a partition is provided in the irrigation tank. The partition divides the irrigation tank into a liquid supply chamber and a waste liquid chamber. The liquid inlet hole is communicated with the liquid supply chamber, and the waste liquid chamber is used to collect the waste liquid after irrigation.
[0008] Furthermore, there are three liquid inlet holes, which are distributed along the axial direction of the same spiral conveying rod, and the diameter b of the liquid inlet hole is equal to the spacing a between adjacent liquid inlet holes; the thickness c of the blade of the spiral conveying rod is equal to half of the pitch of the spiral conveying rod, and c is equal to three times a.
[0009] Furthermore, the lower end of the sliding rod slides through the placement plate, and the two sliding rods on the same constraint belt are fixedly connected by a connecting plate, and the connecting plate is connected to the corresponding piston through a connecting piece; a spring is sleeved on the sliding rod, and the spring is fixedly connected between the connecting plate and the placement plate.
[0010] Furthermore, the connecting member is a pull rope, one end of which is connected to the connecting plate, and the other end of the pull rope is fixedly connected to a connecting rod, and the connecting rod is connected to the piston.
[0011] Furthermore, the flushing unit includes a flushing nozzle, a first connecting pipe, a second connecting pipe and a sliding pipe; one end of the first connecting pipe is connected to the output end of the twin-screw pump, and the other end of the first connecting pipe is connected to the second connecting pipe through a sleeve ring; the end of the second connecting pipe away from the sleeve ring is slidably connected to the sliding pipe, and the flushing nozzle is installed at the end of the sliding pipe away from the second connecting pipe.
[0012] Furthermore, a sliding groove is provided on the sliding tube, and the second connecting tube has a slider slidably arranged in the sliding groove.
[0013] Furthermore, a groove is provided on the placement plate.
[0014] Compared with the prior art, the present invention has the following beneficial effects: as the spiral conveying rod rotates, the liquid inlet hole is intermittently connected to the twin-screw pump, and then the corresponding restraint belt intermittently restrains and fixes the patient's limbs, avoiding long-term compression of the patient's limbs and discomfort caused by poor blood circulation in the patient's limbs. Multiple liquid inlet holes are alternately connected to the twin-screw pump, so that multiple restraint belts alternately restrain the patient's limbs, which can achieve effective fixation of the patient's limbs. At the same time, multiple restraint belts alternately restrain the patient's limbs, forming a certain massage effect, further promoting blood circulation in the limbs, and improving the patient's comfort.
[0015] The change in the number of liquid inlet holes connected to the twin-screw pump causes the flushing pressure on the wound surface to change continuously, which can improve the cleaning efficiency and reduce the risk of injury. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0019] As Figures 1 - 10 shown, the technical solution adopted by the present invention is as follows: An infected wound flushing system includes a flushing tank 1, a flushing unit, a placement plate 24 and a twin-screw pump 10.
[0020] A partition plate 2 is fixedly installed inside the flushing tank 1. The partition plate 2 divides the flushing tank 1 into an independent liquid supply chamber and a waste liquid chamber. The waste liquid chamber is located above the liquid supply chamber. An inlet 3 communicating with the liquid supply chamber and a drain port 4 communicating with the waste liquid chamber are installed on the flushing tank 1. A vertical pipe 5 is fixedly installed on the partition plate 2. The lower end of the vertical pipe 5 communicates with the liquid supply chamber, and the upper end of the vertical pipe 5 extends above the flushing tank 1. The vertical pipe 5 keeps the air pressure inside and outside the liquid supply chamber balanced. The waste liquid chamber is used to collect the waste liquid after flushing.
[0021] A support frame 23 is fixedly installed on one side of the flushing tank 1. A placement plate 24 is fixedly installed on the support frame 23. An arc-shaped groove is formed on the upper end surface of the placement plate 24 to limit the patient's limb. A plurality of restraint straps 25 are arranged on the placement plate 24. Both ends of each restraint strap 25 are fixedly connected with a sliding rod 26. The lower end of the sliding rod 26 slidably penetrates through the placement plate 24. A connecting plate 27 is fixedly connected between the two sliding rods 26 on the same restraint strap 25. And a spring 28 is sleeved on the sliding rod 26 below the placement plate 24. The spring 28 is fixedly connected between the placement plate 24 and the connecting plate 27. When the connecting plate 27 moves downward, the sliding rod 26 moves downward, and the restraint strap 25 moves downward, so that the restraint strap 25 tightens to limit the patient's limb.
[0022] A double-screw pump 10 is fixedly installed at the bottom of the flushing tank 1. The double-screw pump 10 includes a pump body and two spiral conveyor rods 11 rotatably installed in the pump body. A first gear 8 and a second gear 9 are rotatably arranged on the outer side of the pump body. The first gear 8 and the second gear 9 are meshed with each other. One of the spiral conveyor rods 11 is fixedly connected coaxially with the first gear 8, and the other spiral conveyor rod 11 is fixedly connected coaxially with the second gear 9. The flushing tank 1 is fixedly connected with a mounting plate 6. A motor 7 is fixedly installed on the mounting plate 6. The motor shaft of the motor 7 is fixedly connected coaxially with the first gear 8.
[0023] A plurality of liquid inlet holes are formed on the double-screw pump 10. The plurality of liquid inlet holes are all communicated with the flushing tank 1. The output end of the double-screw pump 10 is connected with the flushing unit. The flushing liquid in the liquid supply chamber enters the double-screw pump 10 through the liquid inlet holes, and then enters the flushing unit from the double-screw pump 10 to flush the patient's wound surface. The plurality of liquid inlet holes are distributed along the axial direction of one of the spiral conveyor rods 11. The liquid inlet holes are arranged in cooperation with the blades of the spiral conveyor rod 11. As the spiral conveyor rod 11 rotates, the liquid inlet holes are intermittently communicated with the double-screw pump 10, and the plurality of liquid inlet holes are alternately communicated with the double-screw pump 10.
[0024] A convex part 15 is fixedly arranged in the liquid inlet hole, so that a throttling throat is formed in the liquid inlet hole. At positions corresponding to a plurality of liquid inlet holes on the twin-screw pump 10, a first channel 16 and a second channel 17 are respectively provided. One end of the first channel 16 communicates with the throttling throat of the corresponding liquid inlet hole, and the other end of the first channel 16 communicates with the second channel 17. The end of the second channel 17 facing away from the first channel 16 communicates with the outside. A piston 18 is hermetically and slidably arranged in the second channel 17. A restraint ring 20 for limiting the piston 18 is fixed at the end of the second channel 17 facing away from the first channel 16 to prevent the piston 18 from coming out of the second channel 17. The plurality of liquid inlet holes correspond to a plurality of restraint bands 25 one by one. The piston 18 is connected to the corresponding connecting plate 27 through a connecting member.
[0025] In this embodiment, the connecting member is a pull rope 21. The piston 18 is fixedly connected with a connecting rod 19. One end of the pull rope 21 is fixedly connected with the connecting rod 19, and the other end is fixedly connected with the connecting plate 27. A pulley 22 is arranged on the flushing box 1, and the pull rope 21 bypasses the pulley 22, so that the pull rope 21 can move smoothly.
[0026] When the flushing liquid flows through the liquid inlet hole, due to the Venturi effect, an adsorption force is formed at the throttling throat, and then the corresponding piston 18 moves in the direction close to the first channel 16. The piston 18 drives the corresponding sliding rod 26 to move downward through the connecting rod 19 and the pull rope 21, and the restraint band 25 moves downward, so that the corresponding restraint band 25 is tightened. As the spiral conveyor rod 11 rotates, when the blade of the spiral conveyor rod 11 blocks the liquid inlet hole, under the action of the spring 28, the sliding rod 26 moves upward, the restraint band 25 moves upward, and at the same time the piston 18 resets. Therefore, as the spiral conveyor rod 11 rotates, the liquid inlet hole is intermittently communicated with the twin-screw pump 10, and then the corresponding restraint band 25 intermittently restrains and fixes the patient's limb, avoiding long-term compression of the patient's limb, which may cause poor blood circulation in the patient's limb and discomfort to the patient. And the plurality of liquid inlet holes are alternately communicated with the twin-screw pump 10, so that the plurality of restraint bands 25 alternately restrain the patient's limb, that is, effective fixation of the patient's limb can be realized. At the same time, the plurality of restraint bands 25 alternately restrain the patient's limb, forming a certain massage effect, which further promotes blood circulation of the limb.
[0027] In this embodiment, there are three liquid inlet holes, which are the first liquid inlet hole 12, the second liquid inlet hole 13 and the third liquid inlet hole 14 in sequence. And in this embodiment, as Figure 9 shown, the diameters of the first liquid inlet hole 12, the second liquid inlet hole 13 and the third liquid inlet hole 14 are all b, the interval between the first liquid inlet hole 12 and the second liquid inlet hole 13 and the interval between the second liquid inlet hole 13 and the third liquid inlet hole 14 are both a, and a is equal to b. The width of the blade of the spiral conveyor rod 11 is equal to c, which is half of the pitch of the spiral conveyor rod 11, that is, the distance between the blades of the spiral conveyor rod 11 is equal to the width of the blade, and c = 3a.
[0028] The flushing unit includes a first connecting pipe 29, a second connecting pipe 31, a sliding pipe 32 and a flushing nozzle 35. One end of the first connecting pipe 29 communicates with the output end of the twin-screw pump 10, and the other end of the first connecting pipe 29 is rotatably connected to one end of the second connecting pipe 31 through a collar 30. The end of the second connecting pipe 31 facing away from the collar 30 is slidably connected to the sliding pipe 32, and the flushing nozzle 35 is connected to the end of the sliding pipe 32 facing away from the second connecting pipe 31. A chute 34 is formed in the sliding pipe 32, and a slider 33 is fixed in the second connecting pipe 31. The slider 33 is slidably arranged in the chute 34. The twin-screw pump 10 transports the flushing liquid into the first connecting pipe 29, and then the flushing liquid flows through the second connecting pipe 31 and the sliding pipe 32 in sequence and is sprayed out through the flushing nozzle 35 to flush the wound surface of the patient.
[0029] Working principle: During use, the limb of the patient to be fixed is placed in the groove on the placement plate 24, so that the wound surface is located above the flushing box 1. The flushing liquid is transported into the liquid supply cavity through the water inlet 3.
[0030] The motor 7 is turned on, and the twin-screw pump 10 is started. The flushing liquid in the liquid supply cavity is sucked into the twin-screw pump 10 through the liquid inlet hole, and then flows through the first connecting pipe 29, the second connecting pipe 31 and the sliding pipe 32 in sequence and is sprayed out through the flushing nozzle 35 to flush the wound surface of the patient. The position of the flushing nozzle 35 can be adjusted through the collar 30 and the sliding pipe 32 for convenient flushing. The waste liquid after flushing enters the waste liquid cavity for collection.
[0031] As Figure 10 shown, the blades of the spiral conveyor rod 11 block the first liquid inlet hole 12 and the second liquid inlet hole 13, and the third liquid inlet hole 14 communicates with the inside of the twin-screw pump 10. At this time, the flushing liquid in the liquid supply cavity enters the twin-screw pump 10 through the third liquid inlet hole 14, and the flushing liquid entering the twin-screw pump 10 enters the first connecting pipe 29. When the flushing liquid flows through the throttling orifice of the third liquid inlet hole 14, under the Venturi effect, the corresponding piston 18 slides along the second channel 17 close to the third liquid inlet hole 14. The piston 18 pulls the pull rope 21 through the connecting rod 19, so that the sliding rod 26 moves downward, and further makes the corresponding restraint belt 25 move closer to the placement plate 24 to restrain the limb of the patient. The restraint belts 25 corresponding to the first liquid inlet hole 12 and the second liquid inlet hole 13 are in a relaxed state and will not restrain the limb of the patient.
[0032] As the spiral conveying rod 11 rotates, the first liquid inlet hole 12 gradually disengages from the blade and gradually communicates with the inside of the twin-screw pump 10. When the flushing liquid in the liquid supply cavity flows through the first liquid inlet hole 12, the corresponding piston 18 moves close to the first liquid inlet hole 12, and then the corresponding restraint belt 25 gradually moves downward and approaches the patient's limb. When the first liquid inlet hole 12 is completely communicated with the inside of the twin-screw pump 10, at this time, the first liquid inlet hole 12 and the third liquid inlet hole 14 are in a state of being communicated with the twin-screw pump 10, and the second liquid inlet hole 13 is in a state of being blocked by the blade. At this time, the restraint belts 25 corresponding to the first liquid inlet hole 12 and the third liquid inlet hole 14 restrain the patient's limb.
[0033] As the spiral conveying rod 11 rotates, the third liquid inlet hole 14 is gradually blocked by the blade of the spiral conveying rod 11. When the third liquid inlet hole 14 is completely blocked by the spiral conveying rod 11, since there is no longer flushing liquid flowing through the third liquid inlet hole 14, the piston 18 resets. Under the action of the spring 28, the restraint belt 25 corresponding to the third liquid inlet hole 14 resets and releases the restraint on the patient's limb. At this time, the second liquid inlet hole 13 and the third liquid inlet hole 14 are blocked, and the first liquid inlet hole 12 communicates with the inside of the twin-screw pump 10. At this time, the restraint belt 25 corresponding to the first liquid inlet hole 12 restrains the patient's limb.
[0034] As the spiral conveying rod 11 continues to rotate, the second liquid inlet hole 13 gradually disengages from the blade and gradually communicates with the inside of the twin-screw pump 10. When the second liquid inlet hole 13 communicates with the inside of the twin-screw pump 10, the flushing liquid in the liquid supply cavity enters the twin-screw pump 10 through the second liquid inlet hole 13. The piston 18 corresponding to the second liquid inlet hole 13 moves in the direction close to the second liquid inlet hole 13, and then the restraint belt 25 corresponding to the second liquid inlet hole 13 moves downward and approaches the placement plate 24. When the second liquid inlet hole 13 is completely communicated with the twin-screw pump 10, at this time, the first liquid inlet hole 12 and the second liquid inlet hole 13 are in a state of being communicated with the twin-screw pump 10, and the third liquid inlet hole 14 is in a blocked state. At this time, the restraint belts 25 corresponding to the first liquid inlet hole 12 and the second liquid inlet hole 13 restrain the patient's limb, and the restraint belt 25 corresponding to the third liquid inlet hole 14 is in a relaxed state.
[0035] As the spiral conveying rod 11 continues to rotate, the first liquid inlet hole 12 is gradually blocked by the blade again. During the rotation of the spiral conveying rod 11, one or two liquid inlet holes are simultaneously communicated with the twin-screw pump 10.
[0036] Therefore, as the spiral conveying rod 11 rotates, the liquid inlet holes are intermittently connected to the twin-screw pump 10, thereby enabling the corresponding restraint belts 25 to intermittently restrain the patient's limb, avoiding poor blood circulation in the limb caused by long-term fixation of the limb. At the same time, the three restraint belts 25 alternately restrain the patient's limb, which can effectively fix the patient's limb. Moreover, multiple restraint belts 25 alternately restrain the patient's limb, which has a certain massaging effect on the limb, further facilitating the promotion of blood circulation in the limb and increasing the patient's comfort.
[0037] When only one liquid inlet hole is connected to the twin-screw pump 10, the pressure of the flushing liquid sprayed by the flushing nozzle 35 is relatively small. When gradually two liquid inlet holes are connected to the twin-screw pump 10, the pressure of the flushing liquid sprayed by the flushing nozzle 35 gradually increases. When gradually changing from two liquid inlet holes being connected to the twin-screw pump 10 to only one liquid inlet hole being connected to the twin-screw pump 10, the pressure of the flushing liquid sprayed by the restraint belt 25 gradually decreases. The change in the number of liquid inlet holes connected to the twin-screw pump causes the flushing pressure on the wound surface to continuously change, which can improve the cleaning efficiency, reduce the risk of injury, help control infection, promote wound healing, and improve the safety of debridement.
[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
