Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a rinsing device for post-gynecological surgery. Background Technology

[0002] Postoperative wound cleaning is crucial for preventing infection and promoting healing after gynecological surgery. Postoperative wounds are prone to accumulate blood, exudate, and tissue debris; improper cleaning can lead to infection, adhesions, and even delayed healing. Clinical studies have shown that postoperative irrigation effectively removes contaminants, reduces bacterial colonization, and lowers inflammatory responses; therefore, postoperative irrigation has become a routine clinical nursing practice.

[0003] Currently, existing gynecological postoperative irrigation devices include manual squeezing irrigation devices and electric irrigation devices. Both types of irrigation devices can only perform irrigation. After rinsing the wound site, the irrigation fluid needs to be aspirated back into the abdominal cavity through catheterization, which is cumbersome and has low nursing efficiency. Secondly, the existing irrigation devices have a single method of fixing the irrigation tube / suction tube, which is mostly glued to the abdominal skin with tape. When the patient moves, the tube is easy to shift and rub against the skin, which can lead to local redness, swelling and pain. Summary of the Invention

[0004] This invention aims to provide a flushing device for post-gynecological surgery. An inner suction tube is fitted inside an outer flushing tube. When the outer flushing tube is inserted into the abdominal cavity, the inner suction tube is inserted along with it. A fixing component securely fastens the outer flushing tube to the wound site. Activating the flushing pump flushes the wound site within the abdominal cavity, while activating the suction pump aspirates any accumulated fluid. Flushing and drainage can be completed in a single insertion procedure. The device is simple and convenient to operate, highly efficient in nursing care, and the fixing component provides excellent fixation, effectively preventing tube displacement and skin friction. This invention solves the problems in the prior art.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A post-gynecological irrigation device includes an outer irrigation tube and an inner suction tube. The outer diameter of the inner suction tube is smaller than the inner diameter of the outer irrigation tube, and the inner suction tube passes through the outer irrigation tube. The inlet end of the outer irrigation tube is connected to an irrigation pump, and the inlet end of the irrigation pump is connected to a storage bottle for storing irrigation fluid. The outlet end of the outer irrigation tube has several first through holes. The outlet end of the inner suction tube is connected to a collection bottle, which is connected to the suction pump via a negative pressure tube. The inlet end of the inner suction tube has several second through holes. A fixing component is adjustablely connected to the outer side of the outer irrigation tube for fixing the irrigation device to the patient's wound position.

[0007] Furthermore, a plurality of first through holes are evenly arranged on the side wall of the outer flushing tube, and a plurality of second through holes are evenly arranged on the side wall of the inner suction tube, and the plurality of first through holes and the plurality of second through holes are arranged in a one-to-one manner; when the inner suction tube is rotated, the paired first through holes and second through holes are connected and / or staggered.

[0008] Furthermore, the diameter of the first through hole is not greater than the diameter of the second through hole.

[0009] Furthermore, the outer wall of the flushing outer tube is provided with a limiting platform, and the outer wall of the suction inner tube is connected with a limiting cap that cooperates with the limiting platform; when the limiting cap is fitted onto the limiting platform, the paired first through hole and second through hole are at the same horizontal height.

[0010] Furthermore, the limiting platform is provided with a plurality of conduction marks, and the limiting cap is provided with an indicator mark that cooperates with the conduction marks; when the indicator mark points to different conduction marks, the paired first through hole and second through hole correspond to different connected and / or staggered states.

[0011] Furthermore, the fixing assembly includes a sleeve that is slidably fitted onto the outer wall of the flushing outer tube. The sleeve is connected from top to bottom to a suction cup and an air bladder. The air bladder is connected to an inflation device that controls its inflation state through an air guide tube. The sleeve is also connected above the suction cup to a locking element that controls its sliding and / or locking relative to the flushing outer tube.

[0012] Furthermore, the airbag is ring-shaped, and the ring-shaped airbag is sleeved on the outside of the sleeve.

[0013] Furthermore, the inflation device is a self-recovering inflatable balloon.

[0014] Furthermore, the locking element is a conical nut, which is connected to the sleeve via threads.

[0015] Furthermore, both the storage bottle and the collection bottle are made of transparent material, and both the storage bottle and the collection bottle have scale markings on their outer side walls.

[0016] The principles and beneficial effects of the technical solution are as follows:

[0017] 1. This invention provides a rinsing device for postoperative gynecological surgery, comprising an inner suction tube and an outer rinsing tube. The outer rinsing tube is connected to a storage bottle via a rinsing pump, and a collection bottle connected to the inner suction tube is connected to a suction pump via a negative pressure tube. The inner suction tube is sleeved inside the outer rinsing tube. When rinsing / suctioning the abdominal cavity, the inner suction tube is inserted along with the outer rinsing tube. After the outer rinsing tube is securely fixed to the wound using a fixing component, the rinsing pump is started. The rinsing fluid in the storage bottle flows through the outer rinsing tube and out through the first through-hole to rinse the abdominal wound. The suction pump is then started, and the fluid in the abdominal cavity flows into the inner suction tube through the second through-hole. The inner suction tube guides the fluid into the collection bottle, thus completing the suction of the abdominal fluid. A single insertion can complete the rinsing and drainage of the abdominal wound, making the operation simple, convenient, and highly efficient.

[0018] 2. This invention provides a rinsing device for post-gynecological surgery, wherein a plurality of first through holes are evenly arranged on the side wall of the rinsing outer tube, and a plurality of second through holes are evenly arranged on the side wall of the suction inner tube, with the first and second through holes arranged in a one-to-one correspondence; by rotating the suction inner tube, the paired first and second through holes can be controlled to connect and / or stagger; so that during insertion, rotating the suction inner tube completely staggers the first and second through holes to block and close them, preventing detached muscle tissue from entering the suction inner tube and causing blockage, and preventing muscle tissue from being squeezed into the inner side of the suction inner tube through the first and second through holes during insertion, thus preventing frictional damage to the muscle tissue in the subsequent insertion process; When fluid needs to be aspirated, rotating the inner suction tube fully connects the first and second through holes, effectively improving suction efficiency. If foreign objects obstruct or block the second through hole during suction, the inner suction tube can be rotated periodically. The relative rotation between the inner and outer suction tubes cuts away the foreign object, resolving the blockage. If rotating the inner suction tube fails to resolve the blockage, it can be rotated to completely offset the first and second through holes, increasing the negative pressure of the suction pump to draw the obstruction out. The second through hole is then blocked by the outer suction tube, preventing excessive negative pressure from damaging abdominal muscle tissue. The diameter of the first through hole should not exceed that of the second through hole, ensuring that suctioned material passing through the first through hole can smoothly pass through the second through hole, reducing the risk of blockage.

[0019] 3. This invention provides a rinsing device for post-gynecological surgery. A limiting platform is provided on the outer wall of the rinsing outer tube, and a limiting cap, cooperating with the limiting platform, is connected to the outer wall of the suction inner tube. When the limiting cap is fitted onto the limiting platform, the paired first and second through holes are at the same horizontal height. This allows medical personnel to intuitively understand the relative positional relationship between the intra-abdominal suction inner tube and the rinsing outer tube from outside the body, increasing operational convenience. The limiting platform has several guiding marks, and the limiting cap has indicator marks that cooperate with the guiding marks. When the indicator marks point to different guiding marks, the paired first and second through holes correspond to different connected and / or staggered states. Based on the relative positional relationship between the indicator marks and the guiding marks, medical personnel can know the relative position (connected and / or staggered) of the first and second through holes in the intra-abdominal cavity from the patient's position, facilitating accurate rinsing and / or suction operations, reducing medical accidents, and improving the safety of rinsing and / or suction.

[0020] 4. This invention provides a rinsing device for post-gynecological surgery. The fixing component includes a sleeve that slides onto the outer wall of the rinsing tube. The sleeve is connected to a suction cup and an air bladder. The air bladder is connected to an inflation device via an air tube to control its inflation state. When the rinsing tube is inserted, the sleeve is inserted into the patient's abdominal cavity. The air bladder is positioned inside the abdominal cavity, and the suction cup is positioned outside the abdominal cavity. A locking device controls the sliding and / or locking between the rinsing tube and the sleeve. When the fixing component is fixed to the wound position, the air bladder is inflated using the inflation device, causing it to expand within the abdominal cavity. Simultaneously, the suction cup is adhered to the patient's body surface, acting both inside and outside the wound, which can effectively improve fixation. The components and their fixation effect on the wound location are as follows: The airbag is ring-shaped and fits around the outside of the cannula. When the airbag is inflated, its outer wall evenly abuts against the inner wall of the abdominal cavity, resulting in a large contact area between the inner wall of the abdominal cavity and the airbag, and uniform force on the inner wall of the abdominal cavity, which can effectively improve the fixation effect. The inflation device is a self-recovering inflatable airbag, which is reliable, easy to operate, and has high inflation and deflation efficiency. The locking component is a conical nut, which is connected to the cannula by threads. When it is necessary to lock the irrigation tube, the limiting nut is rotated to make it rotate along the axial direction of the cannula. The effective diameter of the cannula continuously decreases, thereby locking the irrigation tube.

[0021] 5. The present invention provides a flushing device for post-gynecological surgery, wherein both the reservoir bottle and the collection bottle are made of transparent material, and the outer walls of both the reservoir bottle and the collection bottle are marked with graduations, so that during flushing and / or aspiration, the amount of flushing fluid used and the amount of fluid aspirated can be intuitively known, thus ensuring effective flushing and / or aspiration; in addition, by comparing the volumes of the two (the amount of flushing fluid used and the amount of fluid aspirated), medical staff can know whether there is residual fluid in the abdominal cavity (the amount of flushing fluid used is greater than the amount of fluid aspirated) or intra-abdominal bleeding (the amount of fluid aspirated is greater than the amount of flushing fluid used), so as to facilitate subsequent nursing operations.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0029] like Figures 1 to 4As shown, a rinsing device for post-gynecological surgery includes an outer rinsing tube 1 and an inner suction tube 2. The outer diameter of the inner suction tube 2 is smaller than the inner diameter of the outer rinsing tube 1, and the inner suction tube 2 passes through the outer rinsing tube 1. The inlet end of the outer rinsing tube 1 is connected to a rinsing pump 4, and the inlet end of the rinsing pump 4 is connected to a storage bottle 3 for storing rinsing fluid. The outlet end of the outer rinsing tube 1 is evenly provided with several first through holes 9. The outlet end of the inner suction tube 2 is connected to a collection bottle 5, and the collection bottle 5 is connected to a suction pump 6 through a negative pressure tube 7. The inlet end of the inner suction tube 2 is evenly provided with several second through holes 12. The storage bottle 3 and the collection bottle 5 are both made of transparent material, and the outer walls of the storage bottle 3 and the collection bottle 5 are marked with graduations. A fixing component 8 is adjustablely connected to the outer side of the outer rinsing tube 1. The fixing component 8 is used to fix the rinsing device to the position of the patient's wound.

[0030] In this embodiment, the diameter of the first through hole 9 is smaller than the diameter of the second through hole 12, and a plurality of first through holes 9 and a plurality of second through holes 12 are arranged in a one-to-one manner; when the suction inner tube 2 is rotated, the paired first through holes 9 and second through holes 12 are connected and / or staggered.

[0031] The outer wall of the flushing outer tube 1 is provided with a limiting platform 10, and the limiting platform 10 is provided with a number of guiding marks 11. The outer wall of the suction inner tube 2 is connected to a limiting cap 13 that cooperates with the limiting platform 10. The limiting cap 13 is provided with an indicator mark 14 that cooperates with the guiding marks 11. When the limiting cap 13 is sleeved on the limiting platform 10, the paired first through hole 9 and second through hole 12 are at the same horizontal height. And when the indicator mark 14 points to different guiding marks 11, the paired first through hole 9 and second through hole 12 correspond to different connected and / or staggered states.

[0032] The fixing assembly 8 includes a sleeve 15 that is slidably fitted onto the outer wall of the flushing outer tube 1. The sleeve 15 is connected from top to bottom to a suction cup 16 and an airbag 17. The airbag 17 is connected to an inflation device that controls its inflation state through an air guide tube. The sleeve 15 is also connected to a locking member on the upper side of the suction cup 16 to control its sliding and / or locking relative to the flushing outer tube 1. The airbag 17 is ring-shaped and fits onto the outside of the sleeve 15. The inflation device is a self-recovering inflatable airbag 19. The locking member is a conical nut 18, which is connected to the sleeve 15 by threads.

[0033] The specific implementation process is as follows:

[0034] When using this flushing device, first fill the reservoir bottle 3 with an appropriate amount of flushing fluid. Use the graduations on the reservoir bottle 3 to determine the amount of flushing fluid. Then, correctly connect the outer flushing tube 1 to the flushing pump 4, and the flushing pump 4 to the reservoir bottle 3. Also, correctly connect the inner suction tube 2 to the collection bottle 5, and the collection bottle 5 to the negative pressure tube 7 / suction pump 6. The inner suction tube 2 should be fitted inside the outer flushing tube 1. Next, insert the outer flushing tube 1, along with the inner suction tube 2 and the cannula 15 of the fixing assembly 8, into the abdominal cavity. After insertion, the annular balloon 17 should be positioned inside the abdominal cavity, and the suction cup 16 should be positioned outside the abdominal cavity, adhering to the patient's skin. Continue inserting the outer flushing tube 1 (along with the inner suction tube 2) into the abdominal cavity as needed. After the irrigation tube 1 is inserted into the designated position in the abdominal cavity, rotate the conical nut 18 to move it along the axial direction of the sleeve 15, thereby reducing the effective inner diameter of the sleeve 15 and fixing the sleeve 15 to the irrigation tube 1. Then, squeeze the self-recovering inflatable balloon 19 to inflate the ring-shaped balloon 17, effectively fixing the entire fixation assembly 8 to the wound position. Next, accurately fit the limiting cap 13 onto the limiting platform 10, and determine the connection and / or misalignment of the first through hole 9 and the second through hole 12 by using the relative positional relationship of the indicator mark 14 and the conduction mark 11. When irrigating the intra-abdominal wound, start the irrigation pump 4 to perform irrigation. When aspirating intra-abdominal fluid, start the aspiration pump 6 to aspirate the fluid.

[0035] When the fixation component 8 is fixed to the wound position, the airbag 17 is inflated using an inflation device, causing it to expand within the abdominal cavity. Simultaneously, the suction cup 16 is adhered to the patient's body surface, acting both inside and outside the wound to improve the fixation effect of the fixation component 8 to the wound position. The ring-shaped airbag 17 is sleeved on the outside of the cannula 15. When the airbag 17 is inflated, its outer wall evenly abuts against the inner wall of the abdominal cavity, resulting in a large contact area between the inner wall of the abdominal cavity and the airbag 17, and uniform force on the inner wall of the abdominal cavity, thus improving the fixation effect. The inflation device is a self-recovering inflatable airbag 19, which is reliable, easy to operate, and has high inflation and deflation efficiency for the airbag 17. The locking component is a conical nut 18, which is connected to the cannula 15 by threads. When it is necessary to lock the irrigation outer tube 1, the limiting nut is rotated to rotate along the axial direction of the cannula 15, and the effective diameter of the cannula 15 continuously decreases, thus locking the irrigation outer tube 1.

[0036] A limiting platform 10 is installed on the outer wall of the flushing outer tube 1, and a limiting cap 13, which cooperates with the limiting platform 10, is connected to the outer wall of the suction inner tube 2. Medical staff can intuitively know the relative positional relationship between the suction inner tube 2 and the flushing outer tube 1 inside the abdominal cavity from outside the body. Several guiding marks 11 are provided on the limiting platform 10, and indicator marks 14, which cooperate with the guiding marks 11, are provided on the limiting cap 13. Based on the relative positional relationship between the indicator marks 14 and the guiding marks 11, medical staff can know the relative position (connected and / or staggered) of the first through hole 9 and the second through hole 12 inside the abdominal cavity from the patient's position, so as to facilitate accurate flushing and / or suction operations, reduce medical accidents, and improve the safety of flushing and / or suction.

[0037] Rotating the suction inner tube 2 controls the connection and / or offset of the paired first through hole 9 and second through hole 12. During insertion, rotating the suction inner tube 2 completely offsets the first through hole 9 and the second through hole 12 to block and close them, preventing detached muscle tissue from entering the suction inner tube 2 and causing blockage, and preventing muscle tissue from being squeezed into the inner side of the suction inner tube 2 through the first through hole 9 and the second through hole 12 during insertion, thus avoiding frictional damage to the muscle tissue in subsequent insertions. When suctioning accumulated fluid, rotating the suction inner tube 2 completely connects the first through hole 9 and the second through hole 12 to open them, improving suction efficiency. If foreign objects block / block the second through hole 12 during suction, periodically rotate the suction inner tube 2. The inner tube 2 utilizes the relative rotation between the suction inner tube 2 and the flushing outer tube 1 to cut foreign objects, thereby resolving the problem of the suction hole (second through hole 12) being blocked. If rotating the suction inner tube 2 fails to resolve the blockage of the suction hole (second through hole 12), rotating the suction inner tube 2 completely offsets the first through hole 9 and the second through hole 12, increasing the negative pressure of the suction pump 6 to draw the blockage out of the tube. The second through hole 12 is blocked by the flushing outer tube 1, preventing excessive negative pressure suction from damaging the abdominal muscle tissue. The diameter of the first through hole 9 is not larger than the diameter of the second through hole 12, allowing the suction material that passes through the first through hole 9 to pass smoothly through the second through hole 12, reducing the risk of the second through hole 12 being blocked by the suction material.

[0038] Start the flushing pump 4. The flushing fluid in the reservoir bottle 3 flows through the flushing outer tube 1 and out through the first through hole 9 to flush the intra-abdominal wound site. Start the suction pump 6. The effusion in the intra-abdominal cavity flows into the suction inner tube 2 through the second through hole 12. The suction inner tube 2 guides it into the collection bottle 5, thus completing the suction of the intra-abdominal effusion. The flushing and drainage of the intra-abdominal wound site can be completed with one intubation. The operation is simple and convenient and the nursing efficiency is high. Both the reservoir bottle 3 and the collection bottle 5 are made of transparent material, and their outer walls are marked with graduations. This allows for a clear understanding of the amount of irrigation fluid used and the amount of fluid aspirated during flushing and / or aspiration, ensuring effective flushing and / or aspiration. By comparing the volumes of the two (the amount of irrigation fluid used and the amount of fluid aspirated): if the amount of irrigation fluid used is greater than the amount of fluid aspirated, it indicates that there is residual fluid in the patient's abdominal cavity; if the amount of fluid aspirated is greater than the amount of irrigation fluid used, it indicates that there is a high probability of bleeding in the patient's abdominal cavity. Medical staff will refer to these conditions to determine subsequent nursing care.

[0039] The above descriptions are merely embodiments of the present invention, and common knowledge regarding specific technical solutions or characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
