Description

Technical Field

[0001] The invention relates to the technical field of medical device sterilization, in particular to a surgical catheter nursing device used in an interventional operating room. Background Art

[0002] Interventional operating room refers to the operating room where interventional equipment is used on the human body. Interventional devices are medical devices that are temporarily used on the human body to achieve the purpose of auxiliary treatment and disease control. Common interventional devices include intravenous catheters, guide wires, filters, spring emboli, etc. The catheters, guide wires, vascular sheaths and various items used in interventional surgery are mostly disposable. Instruments and items that must be reused should be strictly disinfected and sterilized.

[0003] At present, when using the catheter in the operating room, it is first necessary to flush and sterilize it, and then soak it in a multi-enzyme cleaning solution. However, during the flushing and disinfection process of the catheter, the existing technology generally adopts single-head flushing, and then repeatedly switches the water inlet to achieve back and forth flushing and sterilization in the tube. However, in this method, firstly, it is not easy for the disinfectant to pass through the tube to sterilize the tube wall. Secondly, it is necessary to perform repeated flushing and replacement cleaning, which is cumbersome for the operator. At the same time, when the catheter is used, the surface of the catheter inserted into the skin is generally coated with disinfectant. The traditional method is only to immerse the end of the catheter in the disinfectant. However, this operation will cause the internal tube wall to be contaminated with disinfectant. As the catheter is inserted into the human body, it is easy to cause the contaminated disinfectant to flow back into the human body, causing the problem of fluid accumulation inside the skin. Therefore, a surgical catheter care device for an interventional operating room is proposed to solve the above-mentioned problems. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides a surgical catheter care device for an interventional operating room, which solves the problem that the disinfection and care process of the catheter in the prior art is relatively cumbersome and inconvenient to operate.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a surgical catheter nursing device for an interventional operating room, comprising a sleeve, a fixing cap rotatably connected to the sleeve, the fixing cap being threadedly connected to a water inlet pipe, clamping devices being arranged at both ends of the sleeve, a catheter body being arranged on the clamping device, a circulating recoil device for controlling the continuous forward flushing and back flushing of water flow being arranged inside the sleeve; the circulating recoil device comprising a valve seat, the valve seat sliding inside the sleeve, a sliding rod being connected to the valve seat, one end of the sliding rod being connected to a sliding sleeve, an insert shaft being slidably connected inside the sliding sleeve, a driving handle being fixedly connected to the insert shaft, a driving motor being fixedly installed on the sleeve, and an output end of the driving motor being fixedly connected to the driving handle.

[0006] Preferably, a long groove is provided on the sliding sleeve, the plug shaft is slidably connected to the inside of the long groove, the sliding rod is slidably connected to the sleeve, closing plates are connected on both sides of the valve seat, outlet grooves are provided on the closing plates, two water outlets are provided at the bottom of the sleeve, a water inlet is provided inside the sleeve below the fixing cap, and a liquid medicine immersion device is provided at one end of the valve seat.

[0007] Preferably, the medicine liquid immersion device includes a medicine tank, which is threadedly connected to a sleeve, a flow channel 1 is provided inside the sleeve, a rotating shaft is rotatably connected inside the sleeve, blades are provided on the rotating shaft, and the medicine tank flows into the blades through the flow channel 1.

[0008] Preferably, a plug plate is slidably connected inside the sleeve, a through hole is opened on the plug plate, the plug plate is connected to the valve seat through a connecting rod, a suction tube is slidably connected inside the plug plate, and the plug plate is slidably connected inside the sleeve.

[0009] Preferably, one end of the suction tube is connected to a circular tube, the circular tube is connected to a guide tube, and two groups of rotating shafts and blades are provided, and the two groups of rotating shafts and blades are symmetrically distributed with the center of the circular tube as the symmetry axis.

[0010] Preferably, one end of the sleeve is slidably connected to a pull rod, one end of the pull rod is connected to a partition, a spring sheet is fixedly connected to the pull rod, one side of the spring sheet is connected to a return spring, a flow channel 2 is opened inside the sleeve, one end of the flow channel 2 is connected to the flow channel 1, and the other end of the flow channel 2 is connected to a surface impregnation component.

[0011] Preferably, the surface impregnation component includes a positioning sleeve, a sponge is arranged inside the positioning sleeve, a partition groove is arranged on the positioning sleeve, the partition groove is communicated with the second flow channel, and a plurality of flow holes are opened on the positioning sleeve.

[0012] Preferably, the clamping device comprises a rotating seat, a plurality of nail posts are mounted on the rotating seat, and the catheter body is wound around the plurality of nail posts, and the rotating seat is rotatably connected to the sleeve through a connecting piece.

[0013] Preferably, both ends of the sleeve are threadedly connected with matching caps, and a plug hole matching the diameter of the catheter body is provided inside the matching cap.

[0014] Compared with the prior art, the present invention provides a surgical catheter care device for an interventional operating room, which has the following beneficial effects: 1. The surgical catheter care equipment for interventional operating rooms can control the movement of the valve seat to the left and right positions through the circulating recoil device, thereby controlling the flow direction of the water flow, so that the water flow can be converted from the left end water inlet to the right end as the water inlet, and finally realize the repeated forward flushing and back flushing of the disinfectant in the catheter, thereby realizing efficient sterilization and disinfection of the inside of the catheter.

[0015] 2. The surgical catheter care equipment for interventional operating rooms can achieve internal flushing, disinfection and sterilization by mixing cleaning solution and multiple liquid medicines through the set liquid medicine immersion device, and simultaneously make the sterilization more thorough according to the principle of forward and back flushing. Because the traditional forward flushing method greatly reduces the liquid medicine, the internal disinfection and sterilization are not thorough. The forward and back flushing of the internal liquid can increase the sterilization effect of the catheter.

[0016] 3. The surgical catheter care equipment for interventional operating rooms can automatically immerse the outer surface of the catheter in medicine through the medicine liquid immersion device, without the need for manual insertion and immersion by the operator. This is simple and convenient, and prevents the inside of the catheter from being contaminated with disinfectant, ensuring that no internal fluid will accumulate when it is used on the patient later.

[0017] 4. The surgical catheter care equipment for interventional operating rooms performs disinfection and sterilization care by controlling the insertion and clamping of the two ends of the catheter, making the entire operation process extremely simple and eliminating the need for manual clamping by the operator, thus providing greater convenience for the sterilization of the catheter.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 7 A surgical catheter care device for an interventional operating room includes a sleeve 1, a fixing cap 3 is rotatably connected to the sleeve 1, the fixing cap 3 is threadedly connected to a water inlet pipe, clamping devices 2 are arranged at both ends of the sleeve 1, a catheter body 7 is arranged on the clamping device 2, and a circulating recoil device 5 for controlling the continuous forward flushing and recoil flushing of water flow is arranged inside the sleeve 1.

[0022] In this embodiment, the circulating recoil device 5 includes a valve seat 501, which slides inside the sleeve 1. A sliding rod 502 is connected to the valve seat 501, one end of the sliding rod 502 is connected to a sliding sleeve 503, the interior of the sliding sleeve 503 is slidably connected to an insert shaft 504, the insert shaft 504 is fixedly connected to a driving handle 506, a driving motor 505 is fixedly installed on the sleeve 1, and the output end of the driving motor 505 is fixedly connected to the driving handle 506. The rotation of the driving motor 505 will drive the plug shaft 504 on the driving handle 506 to rotate, and then use the plug shaft 504 to slide in the long groove on the sliding sleeve 503 to convert the circular motion into lateral motion. At this time, the sliding sleeve 503 moves lateral, which will drive the lateral movement of the valve seat 501 through the connection of the sliding rod 502. The lateral movement of the valve seat 501 can control the entry direction of the fluid. When the valve seat 501 is on the right side of the sleeve 1, the fluid will enter from the left end, and the left end becomes the input end, and the right end of the sleeve 1 becomes the output end. When the valve seat 501 is on the left side of the sleeve 1, the fluid will enter from the channel on the right side, and the right side becomes the input end, and the left end of the sleeve 1 becomes the output end, thereby realizing a reciprocating circulation, thereby realizing the sterilization of the inside of the catheter body 7 during the counter-pressure.

[0023] Furthermore, a long groove is provided on the sliding sleeve 503, the plug shaft 504 is slidably connected inside the long groove, the sliding rod 502 is slidably connected to the sleeve 1, and the valve seat 501 on both sides is connected with a closing plate 507, and the closing plate 507 is provided with an outlet groove 508. The bottom of the sleeve 1 is provided with two water outlets 509, and the interior of the sleeve 1 is provided with a water inlet 6 below the fixed cap 3, and one end of the valve seat 501 is provided with a liquid immersion device 4. The flushing disinfectant will enter from the position of the fixed cap 3, and then after passing through the water inlet 6, the water will flow from one side of the valve seat 501, enter the lateral flow channel inside the sleeve 1, and then enter one end of the catheter body 7. After that, the liquid medicine will re-enter the interior of the sleeve 1 from the other end of the catheter body 7, and enter the water outlet 509 on the right side from the outlet groove 508 position of the closing plate 507 on the right side of the valve seat 501, and finally discharge the cleaned waste liquid. Conversely, the same logic is applied to achieve the circulation process. Improve the convenience and thoroughness of the catheter body 7 during the nursing process. Because some traditional technologies directly connect the catheter to the flushing port, the fluid is directly discharged along the catheter, and the residual liquid inside is short, which cannot achieve the effect of sterilization and nursing. In addition, during the operation, the operator's hands need to be continuously clamped, and the sterilization liquid may even be contaminated on the hands, making the overall operation very inconvenient.

[0024] Furthermore, the liquid medicine immersion device 4 includes a medicine tank 401, which is threadedly connected to the sleeve 1, and a flow channel 1 402 is provided inside the sleeve 1. The sleeve 1 is rotatably connected to a rotating shaft 408, and a blade 409 is provided on the rotating shaft 408. The liquid medicine in the medicine tank 401 flows into the blade 409 through the flow channel 1 402. Because the blade 409 is in the lateral flow channel, the fluid will drive the blade 409 to rotate, and then the sterilizing liquid medicine in the medicine tank 401 will flow from the flow channel 1 402 to the position of the blade 409, and enter the interior of the catheter body 7 together with the fluid to achieve flushing, disinfection and sterilization.

[0025] In addition, a plug plate 403 is slidably connected inside the sleeve 1, a through hole 404 is opened on the plug plate 403, the plug plate 403 is connected to the valve seat 501 through a connecting rod, a pumping tube 405 is slidably connected inside the plug plate 403, and the plug plate 403 is slidably connected inside the sleeve 1. One end of the pumping tube 405 is connected to a circular tube 406, and the circular tube 406 is connected to a guide tube 407. Two groups of rotating shafts 408 and blades 409 are provided, and the two groups of rotating shafts 408 and blades 409 are symmetrically distributed with the center of the circular tube 406 as the symmetry axis. The lateral movement of the valve seat 501 will drive the lateral movement of the plug plate 403 through the connecting rod, blocking the flow channel 402, so that the drug liquid enters the interior of the suction tube 405 from the position of the through hole 404, and then flows to the interior of the circular tube 406, and then flows from the position of the guide tube 407 to the blade 409 on the right side. Because the fluid is entering from the right side at this time, the auxiliary drug liquid needs to enter the interior of the catheter body 7 from the entry end to achieve the sterilization effect.

[0026] In addition, one end of the sleeve 1 is slidably connected to a pull rod 410, one end of the pull rod 410 is connected to a partition 411, a spring sheet is fixedly connected to the pull rod 410, one side of the spring sheet is connected to a return spring 414, and a second flow channel 412 is provided inside the sleeve 1, one end of the second flow channel 412 is connected to the first flow channel 402, and the other end of the second flow channel 412 is connected to a surface impregnation component 413. The surface impregnation component 413 includes a positioning sleeve 4134, a sponge 4131 is provided inside the positioning sleeve 4134, a partition 4132 is provided on the positioning sleeve 4134, the partition 4132 is connected to the second flow channel 412, and a plurality of flow holes 4133 are provided on the positioning sleeve 4134. The operator can pull the pull rod 410 outward, and then drive the partition 411 to move horizontally, so that the flow channel 1 402 and the flow channel 2 412 are connected. At this time, the medicine liquid in the medicine tank 401 will enter the interior of the partition 4132 along the flow channel 1 402 and the flow channel 2 412, and then enter the interior of the sponge 4131 through the flow hole 4133 for absorption. At this time, the medicine liquid absorbed by the sponge 4131 will directly adhere to the outer surface of the catheter body 7. As the operator pulls out the catheter body 7, a smearing effect is directly formed.

[0027] It is worth noting that the clamping device 2 includes a rotating seat 201, on which a plurality of nail posts 202 are installed, and the catheter body 7 is wound on the plurality of nail posts 202. The rotating seat 201 is rotatably connected to the sleeve 1 through a connecting piece, and the catheter body 7 is wound and clamped on the plurality of nail posts 202. Because the water flow has a certain impact force during the flushing and disinfection process, if only the clamping of the matching cap 203 is used, it is easy to cause the impact of the impact on the catheter body 7 and cause it to fall off. However, after passing through the plurality of nail posts 202, the force-bearing part of the wound catheter will be subjected to the bending of the nail posts 202 to hinder the detachment effect to a certain extent, thereby increasing the friction force of the catheter body 7, thereby ensuring that the catheter body 7 will not detach during the impact. Both ends of the sleeve 1 are threadedly connected with the matching cap 203, and the inside of the matching cap 203 is provided with a jack adapted to the diameter of the catheter body 7. The matching cap 203 is threadedly connected to the sleeve 1, and the matching cap 203 of different sizes can be replaced according to the catheter body 7 of different diameters.

[0028] Working principle: first, the operator needs to insert the two ends of the catheter body 7 into the inside of the matching cap 203 and dock them in the inside of the sleeve 1. The matching cap 203 and the sleeve 1 are threadedly connected, and the matching caps 203 of different sizes can be replaced according to the catheter body 7 of different diameters. After that, the catheter body 7 is wound and clamped on multiple nail posts 202, because the water flow has a certain impact force during the flushing and disinfection process. If only the clamping of the matching cap 203 is used, it is easy to cause the impact of the impact on the catheter body 7 and cause it to fall off. However, after passing through multiple nail posts 202, the force-bearing part of the wound catheter will be hindered to a certain extent by the bending of the nail posts 202, which increases the friction of the catheter body 7, thereby ensuring that the catheter body 7 will not fall off during the impact. When the installation is completed, the flushing disinfectant will enter from the position of the fixed cap 3, and then after passing through the water inlet 6, the water will flow in from one side of the valve seat 501, enter the horizontal circulation channel inside the sleeve 1, and then enter one end of the catheter body 7. At this time, because the blade 409 is in the horizontal flow channel, the fluid will drive the blade 409 to rotate. Then the sterilizing liquid in the medicine tank 401 will flow from the flow channel 1 402 to the position of the blade 409, and follow the fluid into the interior of the catheter body 7 to achieve flushing, disinfection and sterilization. After that, the liquid will re-enter the interior of the sleeve 1 from the other end of the catheter body 7, and enter the water outlet 509 on the right side from the outlet groove 508 of the closing plate 507 on the right side of the valve seat 501, and finally discharge the cleaned waste liquid. At this time, the rotation of the driving motor 505 will drive the plug shaft 504 on the driving handle 506 to rotate, and then the plug shaft 504 is used to slide in the long groove on the sliding sleeve 503 to convert the circular motion into lateral motion. At this time, the sliding sleeve 503 moves horizontally, and the valve seat 501 will be driven to move horizontally through the connection of the sliding rod 502. After the valve seat 501 moves to the left, the fluid will be blocked by the left end of the lateral channel in the sleeve 1 and will enter from the opened channel on the right. At this time, the fluid will enter the interior of the catheter body 7 from the right channel, and then enter the interior of the sleeve 1 from the left end of the catheter body 7. After that, the miscellaneous liquid will pass through the outlet groove 508 on the left closing plate 507 and enter the water outlet 509 on the left to be discharged. At this time, positive flushing and back flushing in relative directions are formed, so that the liquid medicine can remain in the interior of the catheter body 7 for a long time, and there will also be internal liquid impulse to flush the bacteria inside the catheter, so as to maximize the sterilization effect of the catheter body 7.During the liquid backflow process, the lateral movement of the valve seat 501 will drive the lateral movement of the plug plate 403 through the connecting rod, blocking the flow channel 1 402, so that the liquid medicine enters the interior of the suction tube 405 from the position of the through hole 404, and then flows to the interior of the round tube 406, and then flows from the position of the guide tube 407 to the blade 409 on the right side. Because the fluid enters from the right side at this time, the auxiliary liquid medicine needs to enter the interior of the catheter body 7 from the entry end to achieve the sterilization effect. Therefore, the corresponding flow of the auxiliary liquid medicine can also be automatically controlled during the circulation process. If the operator has completed the sterilization and disinfection, the valve of the water inlet pipe can be closed, and then there will be no impact force of the fluid inside. At this time, the operator can pull the pull rod 410 outward, and then drive the partition 411 to move horizontally, so that the flow channel 1 402 and the flow channel 2 412 are connected. At this time, the medicine in the medicine tank 401 will enter the interior of the partition 4132 along the flow channel 1 402 and the flow channel 2 412, and then enter the interior of the sponge 4131 through the flow hole 4133 for absorption. At this time, the medicine absorbed by the sponge 4131 will directly adhere to the outer surface of the catheter body 7. As the operator pulls out the catheter body 7, a smearing effect is directly formed, and there is no need for the operator to manually smear or liquid immersion operation, so that the care and sterilization effect of the entire catheter is better.
