[0002] A drainage device is a medical device that uses physical principles to drain body fluids or gases. It primarily consists of a transparent bag, container, catheter (including a Luer connector), and screw cap. Its core function is to draw exudate, blood, or gas from the wound or body cavity through negative pressure suction. In the postoperative care of critically ill ICU patients, drainage devices serve as a key tool for removing blood, fluid, and exudate from the surgical site, playing a crucial role in preventing infection and promoting tissue healing.

[0003] When current drainage devices for postoperative care are used, such as abdominal drainage tubes, chest drainage tubes, and wound drainage tubes, blood clots, necrotic tissue debris, and viscous exudates such as pus and serous fluid in the drainage fluid are often deposited in the tube or adhered to the tube wall, resulting in narrowing or even complete blockage of the tube lumen. Blockage or poor fluidity of viscous fluid can lead to local residual fluid accumulation, such as peritoneal effusion and pleural effusion, which in turn leads to the risk of infection, delayed healing or secondary surgery.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0022] In order to solve the problem that blood clots in the drainage fluid are easily deposited in the tube or attached to the tube wall when the drainage device is used, causing the lumen to be narrowed or even completely blocked, which is easy to cause infection and delayed healing risks, and the existing treatment is time-consuming and cumbersome.

The drainage tube 105 is vertically connected to the connecting tube 104. The connecting tube 104, the one-way valve 103, the guide tube 102 and the negative pressure device 101 are connected. The negative pressure device 101 is an existing negative pressure drainage device, which uses the input end of the drainage tube 105 to absorb the patient's effusion, etc., and then guides and collects it through the connecting tube 104 and the guide tube 102.

[0023] The stirring mechanism 2 includes an installation cavity 201 arranged on the inner side of one end of the drainage tube 105, a installation sleeve 202 is provided on the outside of one side of the installation cavity 201, and a mounting seat 203 is fixed to one end of the inner part of the installation sleeve 202, an isolation cover 204 is provided on the inner and outer sides of the installation sleeve 202, and a stator coil 205 is provided on the upper side of the isolation cover 204, a rotating seat 206 is installed on one side of the middle part of the installation seat 203, and an inner rotor 207 is installed on the other side of the rotating seat 206. The stator coil 205 consists of a stator and a wound coil, constituting the existing motor principle.

[0024] The front end of the inner rotor 207 is connected to the first flexible shaft 208, and a magnetic plug 209 is fixed to one end of the first flexible shaft 208. A socket 210 is provided on the opposite side of the magnetic plug 209. A fixing ring 211 is fixed to the outer surface of the first flexible shaft 208, and a stirring blade 212 is fixed to the outer surface of the fixing ring 211. A fitting scraper 213 is installed on the top of the stirring blade 212.

[0025] The stator coil 205 is fixedly connected to the mounting sleeve 202, the mounting seat 203 is threadedly connected to the inner wall of the mounting cavity 201, and the inner rotor 207 is rotatably connected to the mounting seat 203 through the rotating seat 206. The mounting sleeve 202 is screwed together by the threads set on the outer surface of the mounting seat 203 and the threads on the inner wall of the mounting cavity 201, so that the mounting sleeve 202 can be assembled and disassembled with the mounting cavity 201 to facilitate operations before and after use. The insulating isolation cover 204 is attached to the outside of the mounting cavity 201, so that after the mounting sleeve 202 is threadedly installed, the stator coil 205 can be set on the outside of the mounting cavity 201 and the inner rotor 207 can be set on the inside of the mounting cavity 201, and the power cord for powering the stator coil 205 is connected to the outside of the mounting sleeve 202, so that the installed mounting sleeve 202 constitutes an electric motor structure based on the existing principle.

[0026] The first flexible shaft 208 is plugged into the socket 210 through a magnetic plug 209, and the magnetic plug 209 is magnetically connected to the socket 210, and the socket 210 is fixedly connected to the inner rotor 207. There are four groups of stirring blades 212 and fitting scrapers 213 arranged in a ring around the fixed ring 211, and the outer surface of the fitting scraper 213 fits the inner wall of the drainage tube 105. The first flexible shaft 208 passes through the installation cavity 201 and is connected to the socket 210 using the magnetic plug 209. The joint between the first flexible shaft 208 and the installation cavity 201 is just closed, which can prevent liquid leakage. The fitting scraper 213 is made of silicone, and the first flexible shaft 208 is an existing soft and flexible transmission shaft.

[0027] After the existing motor structure formed by the stator coil 205 and the inner rotor 207 is energized, the inner rotor 207 will rotate on the mounting seat 203 using the rotating seat 206. When the first flexible shaft 208 is inserted into the socket 210 on the inner rotor 207 by adsorption using the upper and lower protruding magnetic plugs 209, the rotating inner rotor 207 will drive the first flexible shaft 208 to rotate together, so that the first flexible shaft 208 can rotate in the drainage tube 105. Since the fixing ring 211 is fixed to the outer surface of the first flexible shaft 208, when the first flexible shaft 208 rotates, it can drive the fixing ring 211 and the stirring blade 212 to rotate together in the drainage tube 105, so that when the patient's tissue fluid circulates in the drainage tube 105, the stirring blade 212 can be used to automatically remove blood clots or aggregates. The solid particles are broken up to enhance the fluidity of the drainage fluid, ensure that the accumulated fluid is discharged smoothly through the lumen, reduce residue, and reduce the possibility of infection or slow wound healing caused by residue. The soft silicone scraper 213 can automatically peel off the impurities on the wall of the drainage tube 105 and the stirring blade 212 due to centrifugal rotation during rotation, which is conducive to further improving the circulation effect. At the same time, the scraper 213 can also isolate and support the stirring blade 212 and the wall of the drainage tube 105 to avoid contact between the stirring blade 212 and the drainage tube 105 and damage the drainage tube 105, making the drainage treatment safer. At the same time, after automatic breaking up and dredging, the need for manual intervention and cleaning can be reduced to improve the overall use effect of drainage.

[0028] In order to solve the technical problems that the position is easily offset during rotation cleaning, and the pipe is easily bent and deformed, thus affecting the cleaning and drainage stability, such as Figure 1 、 Figure 2 as well as Figure 6-Figure 8 As shown, the following preferred technical solutions are provided: The front and rear end outer sides of the stirring mechanism 2 are provided with a fixing mechanism 3 for fixed support, and the fixing mechanism 3 includes a fixed end 301 fixed to the rear end of the drainage tube 105 near the connecting tube 104 side, and a wrapping tube 302 is provided on one side of the fixed end 301, and a magnetic ring 303 is installed on the front end surface of the wrapping tube 302, and the magnetic ring 303 is magnetically connected to the fixed end 301, and the wrapping tube 302 is sleeved on the outside of the drainage tube 105. The wrapping tube 302 is a metal bellows, which can wrap and support the soft drainage tube 105 to prevent the drainage tube 105 from being bent or deformed greatly and affecting the internal rotation. The wrapping tube 302 is sleeved from the liquid inlet end of the drainage tube 105 to the fixed end 301 of the metal material, and the liquid inlet end of the drainage tube 105 is not provided with a fixed end 301. After being sleeved, the magnetic ring 303 is used to adsorb and fix the fixed end 301 to prevent the wrapping tube 302 from sliding and displacing at will.

[0029] The fixing mechanism 3 further includes a fixing ring 305 , a connecting frame 306 and a convex ring 307 . The fixing rings 305 are fixed to the outer surfaces of both ends of the first flexible shaft 208 , and the connecting frame 306 is fixed to the outside of the fixing ring 305 .

[0030] The fixing mechanism 3 also includes a sunken groove 308, an outer magnetic ring 309 and a first magnetic ring 304. The outer surface of the connecting frame 306 is wrapped with the outer magnetic ring 309, and the inner surface of the outer magnetic ring 309 is provided with a sunken groove 308. The first magnetic ring 304 is arranged on the outer opposite side of the outer magnetic ring 309, and the first magnetic ring 304 is embedded in the inner surfaces of both ends of the wrapping tube 302. The connecting frame 306 is embedded in the sunken groove 308 by the convex ring 307, and the connecting frame 306 is rotatably connected to the outer magnetic ring 309. When the first soft shaft 208 drives the fixing ring 305 and the connecting frame 306 to rotate.

[0031] Before the installation sleeve 202 is installed, the first flexible shaft 208 is first inserted into the drainage tube 105, and then the first flexible shaft 208 is passed through the installation cavity 201 and connected to the inner rotor 207. As the installation sleeve 202 is installed, the first flexible shaft 208 is pulled back. At this time, the fixing rings 305, the connecting frame 306 and the outer magnetic ring 309 at both ends of the first flexible shaft 208 will move to the first magnetic ring 304 in the wrapped tube 302, and the outer magnetic ring 309 will be stuck in the groove opened on the inner wall of the drainage tube 105, and the connecting frame 306 can rotate between the outer magnetic ring 309, so that while ensuring support, it will not affect the first The normal rotation of the flexible shaft 208 utilizes the magnetic attraction of the first magnetic ring 304 and the outer magnetic ring 309, and the engagement of the outer magnetic ring 309 with the inner wall of the drainage tube 105, so as to fix the front and rear end positions of the first flexible shaft 208, thereby locking the first flexible shaft 208 to ensure that its rotation position does not change forward and backward, and at the same time prevent the front end from separating from the connection between the inner rotor 207, thereby facilitating the effective rotation and cleaning of the first flexible shaft 208. At the same time, the bracket formed by the connecting frame 306 can also support the first flexible shaft 208, so that it is in the middle position of the drainage tube 105, to ensure the stability of the rotation and cleaning.

[0032] In order to solve the technical problem that timely adaptation and adjustment cannot be carried out when the length of the pipeline is changed or when the flexible shaft of a certain section is damaged, such as Figure 1 、 Figure 2 、 Figure 6 as well as Figures 9-11 As shown, the following preferred technical solutions are provided: A connecting mechanism 4 for combined connection is provided in the middle of the stirring mechanism 2, and the connecting mechanism 4 includes a second flexible shaft 401, a combined groove 402 and a plug-in end 403. A combined groove 402 is provided inside the front end of the second flexible shaft 401, and a plug-in end 403 is provided on the outer side of the combined groove 402, and the plug-in end 403 is fixedly connected to the middle of one end of the first flexible shaft 208.

[0033] The connecting mechanism 4 also includes a limit block 404 and a snap ring 405. The limit block 404 is fixed on one side of the outer surface of the plug-in end 403, and the snap ring 405 is fixed on the other side of the outer surface of the plug-in end 403. The plug-in end 403 is plugged into the combination groove 402 through the limit block 404, and the plug-in end 403 is snapped into the combination groove 402 through the snap ring 405. The flexible shaft passing through the interior of the drainage tube 105 is formed by a combination of the first flexible shaft 208 and the second flexible shaft 401, and the combined flexible shaft is provided with three groups of fixing rings 211, stirring blades 212 and fitting scrapers 213, which are respectively arranged at the liquid inlet of the drainage tube 105, the middle of the pipe and the end of the pipe.

[0034] The connecting mechanism 4 also includes a rotating ring 406, a sliding block 407, an adsorption ring 408 and a second magnetic ring 409. The outer surface of the second flexible shaft 401 is provided with a rotating ring 406, and the inner surface of the rotating ring 406 is fixed with a sliding block 407. The outside of the rotating ring 406 is fixed with an adsorption ring 408, and the outer opposite side of the adsorption ring 408 is provided with a second magnetic ring 409.

When the second flexible shaft 401 rotates, the sliding block 407 is used to enable the second flexible shaft 401 and the rotating ring 406 to rotate radially, thereby preventing the rotating ring 406 and the adsorption ring 408 from interfering with the rotation of the second flexible shaft 401.

[0035] By inserting the plug end 403 into the combination groove 402 using the limit block 404 and the snap ring 405, one end of the first flexible shaft 208 and one end of the second flexible shaft 401 can be combined and connected into a whole, and the limit block 404 can ensure the synchronous rotation between the first flexible shaft 208 and the second flexible shaft 401 after the combination, so that before the first flexible shaft 208 passes through the drainage tube 105, according to the length of the selected specific drainage tube 105 and the installation sleeve 202, the combination of the first flexible shaft 208 and the second flexible shaft 401 can be used to adjust the length of the entire flexible shaft, so that the drainage and removal adaptability is better and the drainage effect is guaranteed. The result is that the first flexible shaft 208 and the second flexible shaft 401 that can be detachably assembled can be replaced in a separate area when a certain section is damaged, so as to ensure the use effect of the flexible shaft and avoid the waste of replacing the entire flexible shaft. After the second flexible shaft 401 is assembled and matched, the adsorption ring 408 will be adsorbed with the second magnetic ring 409 on the outside, so that the position of the combined second flexible shaft 401 can be limited. At the same time, the rotating ring 406 and the adsorption ring 408 can support the second flexible shaft 401 so that it is in the middle position of the drainage tube 105. After cooperating with the support of the connecting frame 306, the stability of the rotation can be further guaranteed.
