Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a device for collecting and cleaning exudate around a drainage tube after pancreatic debridement surgery. Background Art

[0002] Severe acute pancreatitis, also known as acute hemorrhagic necrotizing pancreatitis, is a common critical disease in clinical practice. It is caused by the activation of pancreatic enzymes in the pancreas, which causes an inflammatory reaction of pancreatic tissue edema, hemorrhage and necrosis. The main clinical manifestations are varying degrees of abdominal pain and distension, fever, nausea and vomiting, increased blood and urine amylase, extensive bleeding and necrosis. The disease progresses rapidly and is often followed by serious complications such as infection, bleeding, intestinal fistula, pancreatic fistula, deep vein thrombosis of the lower limbs, and multiple organ dysfunction. It is a fatal disease.

[0003] The current surgical treatment for severe acute pancreatitis is "debridement and drainage of pancreatic necrotic tissue". The patient is usually left with several drainage tubes after the operation, and the course of the disease is long.

[0004] After pancreatic debridement, it is common to see exudate from the drainage port around the drainage tube. The exudate is highly corrosive, causing immersion dermatitis and increasing the difficulty of care. The methods for treating exudate in the existing technology are as follows:

[0005] 1. Clean the skin around the wound and spray 3M skin protection film. The doctor will cover the skin around the drainage tube with gauze. However, if there is a lot of exudate, the skin protection film cannot last too long.

[0006] 2. Spray 3M skin protection film and apply hydrocolloid dressing around the drainage tube to protect the skin. If there is a lot of exudate, it may penetrate under the hydrocolloid dressing and continue to corrode the skin.

[0007] Combining the above two methods with the use of ostomy bags combined with negative pressure to collect exudate around the drainage tube, this method is currently effective, but the patient's turning over and body position are affected to a certain extent. The ostomy bag cannot be used for more than three days, and the cost of each dressing change is high. In addition, the nursing workload of medical staff is increased. In order to avoid the use of ostomy bags to reduce dressing costs and reduce the intensity of nursing work for medical staff, we proposed a device for collecting and cleaning exudate around the drainage tube after pancreatic debridement.

The device may be oriented in other ways, and the spatially relative descriptors used herein may be similarly interpreted accordingly.

[0041] like Figures 1 to 8As shown, an embodiment of the present invention provides a device for collecting and cleaning exudate around the drainage tube after pancreatic debridement surgery, including a collection structure 1, a negative pressure extraction device 28 and a collection box 30, wherein the collection box 30 is used to collect the extracted exudate, the negative pressure extraction device 28 is a conventional negative pressure exudate extractor in the prior art, and the collection structure 1, the negative pressure extraction device 28 and the collection box 30 are connected.

[0042] The collecting structure 1 comprises a disc 2, a plurality of slide grooves 3 are provided on the surface of the disc 2, a matching trapezoidal slider 4 is slidably connected to the interior of any of the slide grooves 3, a groove 18 is provided on the bottom surface of any of the trapezoidal sliders 4, a matching movable plate 19 is elastically connected to the interior of any of the grooves 18, two brackets 20 are fixedly installed on the bottom surface of the movable plate 19, a rolling roller 21 is rotatably connected between the two brackets 20, a movable groove 9 is provided through the middle of the disc 2, a seepage collection tube 10 is threadedly connected to the interior of the movable groove 9, an arc guide ring 11 is fixedly connected to the surface of one end of the seepage collection tube 10, and the arc guide ring 11 is used to In order to guide the exudate between the drainage tube body 14 and the wound, an adhesive protective film 12 is fixedly installed on the surface of one end of the arc guide ring 11, a guide tube 13 is fixedly installed inside the exudate collecting tube 10, and the drainage tube body 14 is movably installed inside the guide tube 13. A plurality of guide holes 15 connected with the exudate collecting tube 10 are opened on the end surface of the drainage tube body 14, and a rubber arc ring 16 is fixedly installed on the end surface of the exudate collecting tube 10 on the side away from the arc guide ring 11. A connecting tube 17 connected with the drainage tube body 14 is movably connected on the surface of the rubber arc ring 16, and one end of the connecting tube 17 rotates with the rubber arc ring 16, and the drainage tube body 14 and the connecting tube 17 are connected with each other.

[0043] When the device is in use, the multiple trapezoidal sliders 4 are operated to move toward the center of the wound, so that the rolling roller 21 squeezes the skin and the skin around the wound is bulged at the wound. The wound and the surrounding skin bulge form a height difference with the initial skin state. The second rotating ring 25 rotates with the arc guide ring 11 and the adhesive protective film 12 to rotate in the movable groove 9 toward the wound. The adhesive protective film 12 moves to fit tightly with the raised skin surface. When the extraction end of the drainage tube body 14 is inserted into the wound for drainage, a large amount of exudate will seep out of the drainage tube body 14 and the wound. The exudate will be guided into the exudate collecting tube 10 along the arc guide ring 11. The exudate in the exudate collecting tube 10 is collected through the diversion hole 15, which reduces the contact between the exudate and the adhesive protective film 12, increases the use time of the adhesive protective film 12, prevents the exudate from penetrating under the hydrocolloid dressing to continue to corrode the skin, and avoids further damage to the skin by the exudate.

[0044] The surface of the rolling roller 21 is covered with a rubber sheet layer, which can alleviate excessive squeezing of the skin.

[0045] The exudate collecting tube 10 is used to collect exudate seeping from between the wound and the drainage tube body 14 .

[0046] The skin can be protected by providing the adhesive protective film 12, and the arc-shaped guide ring 11 is in contact with the skin through the adhesive protective film 12, thereby preventing the permeate from flowing out and penetrating under the hydrocolloid dressing to continue corroding the skin.

[0047] like Figure 3 and Figure 4 As shown, a first spring 5 is elastically connected between the trapezoidal slider 4 and the slide slot 3 , one end of the first spring 5 is fixedly connected to the surface of the trapezoidal slider 4 , and the other end of the first spring 5 is fixedly connected to the inner wall of the slide slot 3 .

[0048] The first spring 5 is used for resetting the trapezoidal slider 4, and the first spring 5 makes the trapezoidal slider 4 more stable during the reciprocating motion in the slide groove 3. The movement of multiple trapezoidal sliders 4 causes the rolling roller 21 to move toward the wound, and the skin around the wound is squeezed and bulged to form a height difference with the initial skin state.

[0049] like Figure 3 and Figure 4 As shown, a second spring 22 is elastically connected between the movable plate 19 and the slot 18 , one end of the second spring 22 is fixedly connected to the surface of the movable plate 19 , and the other end of the second spring 22 is fixedly connected to the inner wall of the slot 18 .

[0050] The second spring 22 is used for resetting the movable plate 19 . Under the action of the second spring 22 , the movable plate 19 makes the rolling roller 21 contact with the skin.

[0051] like Figures 2 to 6 As shown, the top surface of the trapezoidal slider 4 is provided with an external thread 6, the upper part of the trapezoidal slider 4 is provided with an arc-shaped rotating ring 7, the inner wall of the arc-shaped rotating ring 7 is provided with an internal thread 8 matching the external thread 6, and the arc-shaped rotating ring 7 is threadedly connected with the trapezoidal slider 4 through the matching of the external thread 6 and the internal thread 8. When the disc 2 is placed;

[0052] The first rotating ring 24 is rotated, and the arc-shaped rotating ring 7 squeezes the multiple trapezoidal sliders 4 to move toward the center of the movable groove 9 through the matching of the external thread 6 and the internal thread 8. The movement of the multiple trapezoidal sliders 4 causes the rolling rollers 21 to move toward the wound. Because the rolling rollers 21 roll on the skin, the rolling of the multiple rolling rollers 21 squeezes the skin. When the skin around the wound is squeezed and bulged, the first rotating ring 24 stops rotating. At this time, the wound and the surrounding skin bulge form a height difference with the initial skin state.

[0053] like Figures 2 to 6As shown, the inner wall of the movable groove 9 is provided with a first thread 26, and the surface of the exudate collecting tube 10 is provided with a second thread 27 matching the first thread 26. The exudate collecting tube 10 is threadedly connected to the movable groove 9 by matching the first thread 26 and the second thread 27. A first rotating ring 24 is fixedly installed on the surface of the arc-shaped rotating ring 7, and a second rotating ring 25 is fixedly installed on the surface of the exudate collecting tube 10. The diameter of the second rotating ring 25 is smaller than the diameter of the first rotating ring 24. A plurality of patches 23 are fixedly installed on the bottom surface of the disc 2.

[0054] It should be noted that the patch 23 is a conventional medical adhesive patch in the prior art. The disc 2 is attached to the wound through the patch 23 so that the position of the movable groove 9 corresponds to the position of the wound. The second rotating ring 25 is manually rotated. At this time, the second rotating ring 25 rotates with the arc guide ring 11 and the adhesive protective film 12 in the movable groove 9 to move toward the wound, so that the adhesive protective film 12 moves to fit the raised skin surface.

[0055] like Figure 1 , Figure 6 , Figure 7 as well as Figure 8 As shown, a plurality of fixing frames 35 are provided on the surface of the guide tube 13, and the guide tube 13 is fixedly connected to the inner wall of the exudate collecting tube 10 through the fixing frames 35. A negative pressure extraction device 28 is provided on one side of the connecting tube 17, and the negative pressure extraction device 28 provides power for extracting the exudate. A hose 29 is provided between the negative pressure extraction device 28 and the connecting tube 17, and the connecting tube 17 is sealed and connected to one end of the negative pressure extraction device 28 through the hose 29. The negative pressure extraction device 28 is a conventional pressure-controllable negative pressure extraction device in the prior art. A collecting box 30 is provided below the negative pressure extraction device 28, and an insert tube 31 is provided between the collecting box 30 and the negative pressure extraction device 28. The collecting box 30 is sealed and connected to the collecting box 30 through the insert tube 31. A breathable plate 32 is fixedly connected to the surface of the collecting box 30, and a liquid level sensor 33 for detecting the liquid level is fixedly installed on the inner wall of the collecting box 30.

[0056] It should be noted that the liquid level sensor 33 is set as a conventional liquid level position sensor in the prior art, and its specific working principle will not be elaborated here. It is used to detect the liquid level of the exudate inside the collection box 30. The liquid level sensor 33 is electrically connected to the existing controller, and the controller itself has a buzzer. When the liquid level reaches the liquid level sensor 33, the buzzer can remind personnel to deal with the exudate inside the collection box 30.

[0057] like Figure 2 , Figures 6 to 8 As shown, a rubber ring 34 is fixedly mounted on the inner wall of one end of the guide tube 13 , and the surface of the drainage tube body 14 is in contact with the rubber ring 34 .

[0058] When the drainage tube body 14 has completed draining the exudate, the exudate will adhere to the surface of the drainage tube body 14 . When the drainage tube body 14 is reset in the guide tube 13 , the rubber band ring 34 can scrape off the exudate on the surface of the drainage tube body 14 to ensure the cleanliness of the surface of the drainage tube body 14 .

[0059] The working process of the technical solution provided by the present invention is as follows:

[0060] Initially, the collection box 30 and the negative pressure extraction device 28 are placed on the bed support table, and the disc 2 is attached above the wound through the patch 23, so that the position of the movable groove 9 corresponds to the position of the wound. During the placement of the disc 2, the rolling roller 21 is squeezed by the body and carries the bracket 20 and the movable plate 19 to squeeze the second spring 22 into the slot 18. When the disc 2 is placed, the first rotating ring 24 is manually rotated. At this time, the arc-shaped rotating ring 7 squeezes multiple trapezoidal sliders 4 to move toward the center of the movable groove 9 through the matching of the external thread 6 and the internal thread 8. The movement of the multiple trapezoidal sliders 4 causes the rolling roller 21 to move toward the wound. Because the rolling roller 21 rolls on the skin, the multiple rolling rollers 21 roll The movement will squeeze the skin. When the skin around the wound is squeezed and bulged, stop rotating the first rotating ring 24. At this time, the wound and the surrounding skin bulge form a height difference with the initial skin state. Then manually rotate the second rotating ring 25. At this time, the second rotating ring 25 rotates with the arc guide ring 11 and the adhesive protective film 12 in the movable groove 9 to move toward the wound. When the adhesive protective film 12 moves to fit the surface of the bulged skin, stop rotating the second rotating ring 25, and manually squeeze the rubber arc ring 16 so that the hand can touch the drainage tube body 14. Because the rubber arc ring 16 is made of flexible rubber, the drainage tube body 14 can move on the guide cylinder 13 at this time, so that the extraction end of the drainage tube body 14 is inserted into the wound for drainage.

[0061] When draining the exudate, a large amount of exudate will seep out of the drainage tube body 14 and the wound. Since the adhesive protective film 12 is tightly attached to the raised skin surface, the exudate will be guided to the exudate collection tube 10 along the arc guide ring 11. In this scheme, multiple trapezoidal sliders 4 move toward the center of the wound, so that the rolling roller 21 squeezes the skin, and the skin around the wound is raised at the wound. The wound and the surrounding skin are raised with a height difference from the initial skin state. The second rotating ring 25 rotates with the arc guide ring 11 and the adhesive protective film 12 to rotate in the movable groove 9 toward the wound. The adhesive protective film 12 moves to fit closely with the raised skin surface. When the extraction end of the drainage tube body 14 is inserted into the wound for drainage, more exudate will seep out of the drainage tube body 14 and the wound. The exudate will be guided into the exudate collecting tube 10 along the arc guide ring 11. The exudate in the exudate collecting tube 10 is collected through the guide hole 15, which reduces the contact between the exudate and the adhesive protective film 12, increases the service life of the adhesive protective film 12, prevents the exudate from penetrating under the hydrocolloid dressing to continue to corrode the skin, and avoids further damage to the skin by the exudate.

[0062] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
