Description

Technical Field

[0001] The present invention relates to the field of medical-related technologies, and in particular to a drainage and flushing device for abdominal drainage observation. Background Art

[0002] Abdominal drainage refers to placing a drainage device (drainage tube or drainage strip) in the abdominal cavity to drain fluid and other things to the outside of the body. Correct abdominal drainage can timely remove effusion, blood accumulation, swelling, gas accumulation, necrotic tissue and foreign matter, improve blood circulation, prevent infection and necrosis, promote inflammation subsidence, ensure good healing of suture sites, reduce the occurrence of complications, and also achieve the purpose of differential diagnosis.

[0003] In the existing abdominal drainage process, such as the Chinese patent with publication number CN117695459B, a special drainage and flushing device for facilitating the observation of abdominal drainage is disclosed, which includes a first pipe and a fourth pipe, wherein the first pipe and the fourth pipe are both connected to a first connecting piece, and the first connecting piece on one side is fixedly connected to a second pipe.

[0004] In the above-mentioned prior art, the flushing and drainage operation is mainly interrupted when an abnormality occurs by cooperating with the sliding rod and the impeller. However, the above-mentioned prior art does not take into account that when the patient has bile leakage, pancreatic leakage and intestinal leakage, it is necessary to drain and remove the waste in time, because bile, pancreatic juice and intestinal contents contain a large number of bacteria and digestive enzymes. If they leak into the abdominal cavity, they may cause severe peritonitis and endanger human health. Moreover, intestinal leakage may be accompanied by feces discharge, which is very easy to cause pipeline blockage and affect the drainage efficiency. In addition, there will be squeezing and friction between the drainage tube inserted into the human body and the human tissue, and the human tissue and the drainage tube may be squeezed and fitted, resulting in the inability to absorb liquid. In this case, the negative pressure inside the drainage tube will act on the human tissue, which may cause the internal blood vessels of the human body to rupture, endangering safety. In addition, for patients, there may be a need to get out of bed and move around, and the drainage equipment needs to be disconnected in a short time. At this time, bacteria may invade from the pipeline, causing wound inflammation, infection, etc.

[0005] Based on this, there is still room for improvement in the above-mentioned prior art. Summary of the invention

[0006] In order to reduce the blockage between the pipe and human tissue and between the pipe and impurities during abdominal drainage and flushing, and to ensure the smoothness and safety of drainage and flushing, the present application provides a drainage and flushing device for abdominal drainage observation.

[0007] The present application provides a drainage and flushing device for peritoneal drainage observation using the following technical solution:

[0008] A drainage and flushing device for observation based on abdominal drainage includes a drainage tube, a flushing tube, an anti-blocking module, an isolation module, a drip module, a suction module, and an extension tube. The drainage tube is inserted into the patient's body for drainage, and the drainage tube has a negative pressure protection function for the patient. The flushing tube is inserted into the interior of the drainage tube, and the flushing tube is a retractable combined structure. The anti-blocking module is evenly arranged on the flushing tube along the length direction, and the anti-blocking module clears the gap between the drainage tube and the flushing tube to prevent blockage. The isolation module is arranged at the outer end of the flushing tube, and the isolation module isolates and closes the outer end of the flushing tube. The drip module is connected and cooperated with the isolation module, and the drip module outputs physiological saline to the flushing tube for flushing operation. The suction module is connected to the drainage tube through the extension tube, and the suction module creates negative pressure to suck and discharge the accumulated fluid in the patient's body.

[0009] Preferably, the cross-section of the drainage tube is circular, suction holes are evenly opened on the outer periphery of the end of the drainage tube, and a concave chamfer is provided on the outside of the suction hole. The setting of the concave chamfer enlarges the opening of the suction hole, which is conducive to the entry of accumulated fluid and hard impurities and is not easy to be blocked. The suction hole is evenly opened with anti-blocking holes along its inner circumference. When the drainage tube is inserted into the human body, the internal tissues of the human body (muscles, internal organs, etc.) will cause a certain amount of squeezing on the drainage tube, which may squeeze and block the suction hole, thereby causing the accumulated fluid to be unable to be discharged, and continuous negative pressure will attract and stretch the part of the tissue that blocks the suction hole, which may cause fragile capillaries to rupture, resulting in internal bleeding. The opening of the anti-blocking holes increases the flow space. At the same time, the continuous anti-blocking holes form a wave groove structure, which is not easily completely blocked by human tissue, reducing the risk of bleeding in the patient.

[0010] Preferably, the inner end of the flushing pipe is equipped with reinforcing rings at evenly spaced intervals along the length direction. The reinforcing rings with a hard structure play a supporting role (the length of the reinforcing rings is short and does not affect the bending of the flushing pipe). The left end of the reinforcing ring is fixedly connected to the flushing pipe, and the right end of the reinforcing ring is slidably fitted with the flushing pipe through an auxiliary part. The auxiliary part is installed on the flushing pipe, and a spring is connected between the reinforcing ring and the auxiliary part, which acts as a reset.

[0011] Preferably, the anti-blocking module includes a connecting piece, a rotating ring, a rotating groove, a scraper blade, and an extrusion piece. One end of the connecting piece is connected to the inner end of the flushing tube, and the other end of the connecting piece is connected to the inner end of the drainage tube. The rotating ring is rotatably arranged on the outer periphery of the reinforcement ring. A second spring is connected between the rotating ring and the reinforcement ring. The second spring is a torque spring. The second spring plays a resetting role. A rotating groove is provided on the rotating ring. Scraper blades are evenly installed on the outer periphery of the rotating ring. The extrusion piece is slidably arranged on the reinforcement ring from left to right. The right end of the extrusion piece is connected to the auxiliary piece. The cross-section of the extrusion piece is arc-shaped. An inclined extrusion angle is provided on one side of the extrusion piece. The extrusion piece and the rotating groove are extrusion-fitted.

[0012] Preferably, the rotating rings and the suction holes are arranged in a staggered manner to prevent larger solid impurities from being blocked by scraper blades when being sucked from the suction holes.

[0013] Preferably, the isolation module includes an outer shell member, a connecting head, an isolation assembly, a locking mechanism, and a closing plate. The outer shell member is installed at the outer end of the flushing pipe, the connecting head is slidably arranged inside the outer shell member, a spring three is connected between the connecting head and the outer shell member, and the spring three plays a resetting role. The isolation assembly is arranged at the lower end of the outer shell member, the locking mechanism is arranged in the outer shell member, the closing plate is slidably arranged at the lower end of the connecting head, and the closing plate in the initial state closes the lower end of the connecting head. A spring four is connected between the closing plate and the connecting head, and the spring four plays a resetting role.

[0014] Preferably, the isolation assembly includes a partition plate, a rotating roller, a traction belt, a sliding member, and a pressing member. The partition plate is slidably arranged at the lower end of the outer shell member. The partition plate in an initial state closes the lower end of the outer shell member. A spring five is connected between the partition plate and the outer shell member, and the spring five plays a resetting role. The rotating roller is rotatably arranged on an auxiliary bracket, and the auxiliary bracket is installed in the outer shell member. One end of the traction belt is fixedly connected to the upper surface of the partition plate, and the other end of the traction belt is connected to the sliding member after passing through the rotating roller. The sliding member is slidably arranged on the side wall of the outer shell member, and the pressing member is installed at the lower end of the outer wall of the connecting head, and the positions of the pressing member and the sliding member correspond.

[0015] Preferably, the locking mechanism includes a locking plate, an extrusion groove, and an unlocking piece. The locking plate is slidably arranged in the side wall of the outer shell member, and a spring six is ​​connected between the locking plate and the outer shell member. The spring six always tends to push the locking plate toward the connecting head. An extrusion groove is provided on the locking plate, and a locking groove corresponding to the position of the locking plate is provided on the connecting head. The unlocking piece is slidably arranged in the side wall of the outer shell member up and down, and a spring seven is connected between the unlocking piece and the outer shell member. The lower end of the unlocking piece is a spherical structure that is convenient for extrusion, and the position of the unlocking piece corresponds to the extrusion groove.

[0016] Preferably, the drip module is composed of an infusion bottle and an infusion set, and both the infusion bottle and the infusion set are prior art.

[0029] The following is combined with Figure 1-Figure 8 This application is described in further detail.

[0030] The embodiment of the present application discloses a drainage and flushing device for abdominal drainage observation, which avoids the harm of negative pressure to the human body by preventing excessive contact with human tissue, and at the same time cuts and stirs the blockages between pipes to ensure smooth drainage.

[0031] Reference Figure 1 , Figure 2 As shown, a drainage and flushing device for observation based on abdominal drainage includes a drainage tube 1, a flushing tube 2, an anti-blocking module 3, an isolation module 4, a drip module 5, a suction module 6, and an extension tube 7. The drainage tube 1 is inserted into the patient's body for drainage, and the drainage tube 1 has a negative pressure protection function for the patient. The flushing tube 2 is inserted into the interior of the drainage tube 1, and the flushing tube 2 is a retractable combined structure. The anti-blocking module 3 is evenly arranged on the flushing tube 2 along the length direction. The anti-blocking module 3 dredges the gap between the drainage tube 1 and the flushing tube 2 to prevent blockage. The isolation module 4 is arranged at the outer end of the flushing tube 2, and the isolation module 4 isolates and closes the outer end of the flushing tube 2. The drip module 5 is connected and matched with the isolation module 4. The drip module 5 outputs physiological saline to the flushing tube 2 for flushing operation. The suction module 6 is connected to the drainage tube 1 through the extension tube 7, and the suction module 6 creates negative pressure to suck and discharge the effusion in the patient's body.

[0032] In the actual working process, the drainage tube 1 is implanted in the patient after surgery. After that, the suction module 6 is connected to the drainage tube 1 using the extension tube 7, and the drip module 5 is connected to the flushing tube 2. The isolation module 4 is triggered to open, and the flushing tube 2 is unblocked. Subsequently, the drip module 5 outputs saline through the drainage tube 1. The saline dilutes the accumulated fluid to make it easy to flow, and the saline also flushes the patient's wound. At the same time, the suction module 6 is started to generate negative pressure, and the accumulated fluid in the patient's body is sucked into the suction module 6 through the drainage tube 1 and the extension tube 7. The patient's recovery condition can be judged by observing the accumulated fluid condition inside the drainage tube 1. When the drainage tube 1 is blocked, the flushing tube 2 is slightly pulled to trigger the anti-blockage module 3, and the anti-blockage module 3 removes the impurities that cause the blockage. Cut and stir to clear the drainage tube 1. When the patient needs to get out of bed and move around (medically it is recommended that patients get out of bed and move around to facilitate recovery), disconnect the extension tube 7 and the drip module 5. At this time, the isolation module 4 automatically seals the exposed end of the flushing tube 2 to prevent infection by viruses, dirt, etc. The exposed end of the drainage tube 1 needs to be tied and sealed with a plastic bag (the standard is a special drainage bag, but it can also be replaced with a fresh-keeping bag, medical plastic gloves, etc.) to receive the leaked accumulated fluid. This application has targetedly dealt with the negative pressure that may damage blood vessels during drainage and flushing, as well as the problem of foreign body blockage. At the same time, in order to take care of the patient's need to get out of bed and move around, a double-sealing measure is taken for the flushing tube 2 that needs to be kept clean to prevent viruses from invading the human body and ensure the health and safety of patients.

[0033] Reference Figure 3 As shown, the cross-section of the drainage tube 1 is circular, and suction holes 11 are evenly opened on the outer periphery of the end of the drainage tube 1. The outside of the suction hole 11 is provided with a concave chamfer. The setting of the concave chamfer enlarges the opening of the suction hole 11, which is conducive to the entry of accumulated fluid and hard impurities and is not easy to be blocked. The suction hole 11 is evenly provided with anti-blocking holes 12 along its inner circumference. When the drainage tube 1 is inserted into the human body, the internal tissues of the human body (muscles, internal organs, etc.) will cause a certain amount of squeezing on the drainage tube 1, which may squeeze and block the suction hole 11, thereby causing the accumulated fluid to be unable to be discharged, and the continuous negative pressure will attract and stretch the part of the tissue that blocks the suction hole 11, which may cause fragile capillaries to rupture, resulting in internal bleeding. The opening of the anti-blocking holes 12 increases the flow space. At the same time, the continuous anti-blocking holes 12 form a wave groove structure, which is not easily completely blocked by human tissues, reducing the risk of bleeding in the patient.

[0034] Reference Figure 4-Figure 6As shown, in order to prevent the gap between the drainage tube 1 and the flushing tube 2 from being blocked and causing drainage failure, the present application is provided with an anti-blocking module 3, which includes a connecting member 31, a rotating ring 32, a rotating groove 33, a scraper blade 34, and an extrusion member 35. One end of the connecting member 31 is connected to the inner end of the flushing tube 2, and the other end of the connecting member 31 is connected to the inner end of the drainage tube 1. The rotating ring 32 is rotatably arranged on the outer periphery of the reinforcement ring 21, and a spring 2 is connected between the rotating ring 32 and the reinforcement ring 21. The spring 2 is a torque spring, and the spring 2 plays a resetting role. A rotating groove 33 is provided on the rotating ring 32, and scraper blades 34 are evenly installed on the outer periphery of the rotating ring 32. The extrusion member 35 is slidably arranged on the reinforcement ring 21 left and right, and the right end of the extrusion member 35 is connected to the auxiliary member 22. The cross-section of the extrusion member 35 is arc-shaped, and an inclined extrusion angle is provided on one side of the extrusion member 35. The extrusion member 35 and the rotating groove 33 are extrusion-fitted.

[0035] Reference Figure 4 As shown, the rotating rings 32 and the suction holes 11 are arranged in a staggered manner to prevent larger solid impurities from being blocked by the scraper blades 34 when being sucked from the suction holes 11 .

[0036] Reference Figure 5 As shown, the inner end of the flushing pipe 2 is evenly spaced along the length direction with reinforcing rings 21, and the reinforcing ring 21 with a hard structure plays a supporting role (the length of the reinforcing ring 21 is short and does not affect the bending of the flushing pipe 2). The left end of the reinforcing ring 21 is fixedly connected to the flushing pipe 2, and the right end of the reinforcing ring 21 is slidably matched with the flushing pipe 2 through an auxiliary part 22. The auxiliary part 22 is installed on the flushing pipe 2, and a spring is connected between the reinforcing ring 21 and the auxiliary part 22, and the spring acts as a reset.

[0037] In the actual anti-clogging process, the exposed end of the flushing tube 2 is pulled. Since the inner end of the flushing tube 2 is fixed to the drainage tube 1 through the connecting piece 31, the flushing tube 2 is pulled and stretched, and relative sliding occurs between the reinforcement ring 21 and the auxiliary piece 22. The extrusion piece 35 is pulled by the auxiliary piece 22 and displaced. The moving extrusion piece 35 squeezes the rotating groove 33 to rotate the rotating ring 32, and the scraper blade 34 rotates with the rotating ring 32 to stir and clean the impurities that cause the blockage. At the same time, when the flushing tube 2 is pulled and stretched, the scraper blade 34 is also displaced along the length direction of the flushing tube 2, and the impurities that cause the blockage are also cut, thereby realizing the operation of the scraper blade 34 cutting in a straight line while rotating and stirring, which is conducive to dredging.

[0038] Reference Figure 7As shown, the present application is provided with an isolation module 4 to seal the exposed end of the flushing pipe 2, and the isolation module 4 includes a shell member 41, a connector 42, an isolation assembly 43, a locking mechanism 44, and a closing plate 45. The shell member 41 is installed at the outer end of the flushing pipe 2, and the connector 42 is slidably arranged inside the shell member 41, and a spring three is connected between the connector 42 and the shell member 41, and the spring three plays a resetting role. The isolation assembly 43 is arranged at the lower end of the shell member 41, and the locking mechanism 44 is arranged in the shell member 41. The closing plate 45 is slidably arranged at the lower end of the connector 42, and the closing plate 45 in the initial state closes the lower end of the connector 42, and a spring four is connected between the closing plate 45 and the connector 42, and the spring four plays a resetting role.

[0039] During the actual isolation process, when the drip module 5 is connected to the isolation module 4, the closing plate 45 is squeezed downward by the drip module 5, thereby opening the connecting head 42. When the closing plate 45 moves to the maximum distance, the connecting head 42 moves downward synchronously. The downward moving connecting head 42 triggers the isolation assembly 43, and the outer shell 41 is unobstructed. At the same time, the locking mechanism 44 locks the position of the connecting head 42.

[0040] Reference Figure 7 As shown, the isolation assembly 43 includes a partition plate 431, a rotating roller 432, a traction belt 433, a sliding member 434, and a pressing member 435. The partition plate 431 is slidably arranged at the lower end of the outer shell 41. The partition plate 431 in the initial state closes the lower end of the outer shell 41. A spring five is connected between the partition plate 431 and the outer shell 41, and the spring five plays a resetting role. The rotating roller 432 is rotatably arranged on an auxiliary bracket, and the auxiliary bracket is installed in the outer shell 41. One end of the traction belt 433 is fixedly connected to the upper surface of the partition plate 431, and the other end of the traction belt 433 is connected to the sliding member 434 after passing through the rotating roller 432. The sliding member 434 is slidably arranged on the side wall of the outer shell 41, and the pressing member 435 is installed at the lower end of the outer wall of the connecting head 42, and the pressing member 435 corresponds to the position of the sliding member 434.

[0041] During operation, the pressing member 435 follows the connector 42 to descend, and the descending pressing member 435 presses the sliding member 434 to descend, and the traction belt 433 is pulled. Under the action of the rotating roller 432, the direction of the force is changed, and the partition plate 431 is pulled up, so that the outer shell 41 is unobstructed.

[0042] Reference Figure 7 , Figure 8As shown, the locking mechanism 44 includes a locking plate 441, an extrusion groove 442, and an unlocking member 443. The locking plate 441 is slidably arranged in the side wall of the outer shell member 41, and a spring six is ​​connected between the locking plate 441 and the outer shell member 41. The spring six always pushes the locking plate 441 toward the connecting head 42. An extrusion groove 442 is provided on the locking plate 441, and a locking groove 421 corresponding to the position of the locking plate 441 is provided on the connecting head 42. The unlocking member 443 is slidably arranged in the side wall of the outer shell member 41 up and down, and a spring seven is connected between the unlocking member 443 and the outer shell member 41. The lower end of the unlocking member 443 is a spherical structure that is conducive to extrusion, and the position of the unlocking member 443 corresponds to the extrusion groove 442.

[0043] During the actual locking process, when the connecting head 42 descends so that the positions of the locking groove 421 and the locking plate 441 correspond, the locking plate 441 extends into the locking groove 421 under the action of spring six to lock the position of the connecting head 42. At the same time, the moved extrusion groove 442 is located below the unlocking member 443. When unlocking is required, the unlocking member 443 is pressed, and the unlocking member 443 squeezes the extrusion groove 442 to make the locking plate 441 retreat and reset, thereby unlocking the connecting head 42. At this time, the connection of the drip module 5 can be disconnected.

[0044] Reference Figure 1 As shown, the drip module 5 is composed of an infusion bottle and an infusion set, both of which are prior art. When working, the end of the infusion set is inserted into the connector 42.

[0045] Reference Figure 1 As shown, the suction module 6 is composed of a dirt storage container and a negative pressure device. When working, the negative pressure device is responsible for creating negative pressure, and the dirt storage container stores the sucked dirt.

[0046] The implementation principle of this embodiment is:

[0047] Step 1: The patient is implanted with a drainage tube 1;

[0048] Step 2: Use the extension tube 7 to connect the suction module 6 to the drainage tube 1;

[0049] Step 3: Connect the drip module 5 to the flushing pipe 2, the isolation module 4 is triggered to open, and the flushing pipe 2 is unblocked;

[0050] Step 4: The drip module 5 outputs saline through the drainage tube 1, and the saline dilutes the effusion and rinses the patient's wound. At the same time, the suction module 6 starts to generate negative pressure, and the effusion in the patient's body is sucked into the suction module 6 through the drainage tube 1 and the extension tube 7;

[0051] Step 5: Observe the fluid accumulation inside the drainage tube 1 to determine the patient's recovery;

[0052] Step 6: When the drainage tube 1 is blocked, the flushing tube 2 is slightly pulled to trigger the anti-blocking module 3, and the anti-blocking module 3 cuts and stirs the impurities that cause the blockage, thereby clearing the drainage tube 1;

[0054] A. Disconnect the extension tube 7 and the drip module 5, and the isolation module 4 automatically seals the exposed end of the flushing tube 2;

[0055] B. Use a plastic bag to tie and seal the exposed end of the drainage tube 1.

[0056] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
