[0036] The present application will be further described in detail by specific embodiments with reference to the accompanying drawings.

[0037] Embodiment 1

[0038] Please refer to Figures 1 to 4This invention provides a technical solution: a common surgical anti-blockage abdominal drainage device, comprising a drainage tube 1, an injection bottle 2 disposed on the upper left side of the drainage tube 1, an irrigation tube 3 fixedly inserted into the bottom of the injection bottle 2, the side of the irrigation tube 3 away from the injection bottle 2 extending into the interior of the drainage tube 1, a media bladder 4 disposed on the right side of the drainage tube 1, a connecting tube 5 fixedly inserted into the left side of the media bladder 4, the end of the connecting tube 5 away from the media bladder 4 penetrating the drainage tube 1 and passing through the irrigation tube 3, and a fixed elastic bladder 10 is inserted therein, a drainage hole 11 is provided at the top of the drainage tube 1, and an agitation component 6 is disposed on the top inner side of the drainage tube 1, the agitation component 6 including a threaded frame 61 fixedly connected to the bottom of the outer wall of the connecting tube 5 and located below the elastic bladder 10, the threaded frame 61... The bottom outer wall of the frame 61 is threaded, and a threaded sleeve 62 is threadedly connected to the threaded part of the bottom outer wall of the threaded frame 61. The bottom inner wall of the threaded sleeve 62 is rotatably connected to the top outer wall of the flushing pipe 3 that extends into the drainage pipe 1. Agitators 63 are fixedly connected to both sides of the bottom outer wall of the threaded sleeve 62. The parts of the flushing pipe 3 and the connecting pipe 5 that extend into the drainage pipe 1 are made of rigid material. The top axis of the flushing pipe 3 that extends into the drainage pipe 1 is consistent with the top axis of the connecting pipe 5 that extends into the drainage pipe 1. The top of the threaded frame 61 has a trumpet-shaped structure. The top of the drainage pipe 1 is narrow at the top and wide at the bottom. A flushing hole 12 is opened on the top of the ring side of the flushing pipe 3 that extends into the drainage pipe 1. The flushing hole 12 corresponds to the position of the drainage hole 11.

[0039] By adopting the above technical solution, a fixing ring is fixedly connected to the top of the injection bottle 2. When in use, the injection bottle 2 is hung on the external hook through the fixing ring. When in use, a liquid pump can be installed near the injection bottle 2 in the flushing tube 3 to adjust the flow rate and pressure of physiological saline inside the flushing drainage tube 1. The bottom of the drainage tube 1 can be connected to a negative pressure adsorption device to provide negative pressure inside the drainage tube 1, so that abdominal drainage can be performed smoothly.

[0040] If a blockage occurs during drainage, the media bladder 4 needs to be pressed continuously. When the media bladder 4 is pressed, the viscous medium in the media bladder 4 enters the interior of the connecting tube 5, and the medium flows inside the connecting tube 5 and enters the interior of the elastic bladder 10. When the hand is released, under the elastic force of the elastic bladder 10 itself, the medium returns to the interior of the media bladder 4 through the connecting tube 5. Therefore, when the media bladder 4 is pressed continuously, the elastic bladder 10 continuously contracts and expands, which can agitate the liquid inside the drainage tube 1 to eliminate the blockage problem of the drainage tube 1 and ultimately achieve the purpose of smooth drainage.

[0041] The design of the drainage tube 1 is narrow at the top and wide at the bottom, so that when the elastic bag 10 expands, the top opening of the drainage tube 1 can be timely blocked, so as to improve the flow effect of the liquid in the drainage tube 1 when the elastic bag 10 expands to push the liquid, thereby improving the ability to solve the blockage problem in the drainage tube 1.

[0042] When the elastic bag 10 expands, the bottom of the elastic bag 10 extrudes the threaded frame 61, so that the threaded frame 61 moves downward, and under the action of the threaded connection, the threaded sleeve 62 rotates, so that the stirring frame 63 rotates, and when the stirring frame 63 stirs, the pus and pus moss can be stirred, which is beneficial to break the adhesion of the pus and pus moss, thereby improving the effect of preventing abdominal cavity drainage from being blocked.

[0043] It should be noted that the threaded pitch of the threaded frame 61 is set to be large, which is beneficial to reduce the friction during movement, and the threaded frame 61 is similar to the connection mode between the hand-pushed flying saucer screw part and the flying saucer.

[0044] Specifically, as shown in Figures 1 to 4 and Figure 7 , the bottom of the drainage tube 1 is provided with an electromagnetic valve 9, and the right part of the flushing pipe 3 is fixedly provided with a micro liquid flow sensor 13.

[0045] By adopting the above technical scheme, when the medium bag 4 is pressed, the medium in the communication pipe 5 flows from the medium bag 4 to the elastic bag 10, at this time the micro liquid flow sensor 13 detects the liquid flow and transmits a signal to the external controller, and the controller controls the electromagnetic valve 9 to close. When the elastic bag 10 expands, the top opening of the drainage tube 1 is blocked, and the electromagnetic valve 9 is closed, at this time the area inside the drainage tube 1 close to the drainage hole 11 is in a closed state except the drainage hole 11, so when the elastic bag 10 continues to expand, the liquid in the drainage tube 1 flows from the inside to the outside through the drainage hole 11, thereby facilitating the drainage hole 11 to be dredged. Such a design further improves the effect of preventing abdominal cavity drainage from being blocked.

[0046] Specifically, as shown in Figures 1 to 4 , the stirring frame 63 is provided with a groove 64 on the side away from the threaded sleeve 62, the inner wall of the drainage tube 1 is fixedly connected with an auxiliary plate 65 at a position corresponding to the groove 64, the inner wall bottom of the threaded sleeve 62 is fixedly connected with the top of the flushing pipe 3, and the top of the threaded sleeve 62 is fixedly connected with the outer wall of the top of the threaded frame 61. The top of the threaded sleeve 62 is fixedly connected with the second flexible film 67 between the top of the threaded sleeve 62 and the outer wall of the top of the threaded frame 61.

[0047] By adopting the above technical scheme, when the stirring frame 63 rotates, the relative movement occurs between the stirring frame 63 and the auxiliary plate 65 because the auxiliary plate 65 is fixed to the inner wall of the drainage tube 1, and the auxiliary plate 65 can pass from the inside of the groove 64 when the stirring frame 63 rotates, and the auxiliary plate 65 can cooperate with the stirring frame 63 to improve the crushing effect on the coagulated pus and pus moss, and further improve the effect of preventing the abdominal cavity drainage from being blocked.

[0048] The first flexible film 66 and the second flexible film 67 are beneficial to guarantee the sealing of the threaded connection, and avoid affecting the threaded connection between the threaded frame 61 and the threaded sleeve 62.

[0049] It should be noted that the threaded frame 61 moves up and down within a limited distance, so that the stirring frame 63 does not rotate for one circle, the first flexible film 66 and the second flexible film 67 are large in size and elastic, and do not affect the rotation of the threaded sleeve 62.

[0050] Specifically, as shown in Figures 2 to 6 The top of the drainage tube 1 is provided with a scraping assembly 7, the scraping assembly 7 includes a linear array of scraping rings 71 movably connected to the top of the outer wall of the drainage tube 1, a plurality of scraping rings 71 are fixedly connected together, the top of the bending frame 72 extends into the inside of the drainage tube 1 and is fixedly connected to the top of the ring side of the threaded frame 61, the outer wall of the bending frame 72 is slidably connected to the drainage tube 1, and the U-shaped elastic sheet 74 is fixedly connected between the top of the bending frame 72 and the inner side of the drainage tube 1.

[0051] By adopting the above technical scheme, when the medium enters the inside of the elastic bag 10, the threaded frame 61 moves downward, so that the bending frame 72 moves downward, and then the plurality of scraping rings 71 move, so that the scraping rings 71 can scrape the outer wall of the drainage tube 1 corresponding to the drainage hole 11, and further improve the effect of dredging the drainage hole 11, and further improve the effect of preventing the abdominal cavity drainage from being blocked.

[0052] When the elastic bag 10 extrudes the threaded frame 61, the U-shaped elastic sheet 74 deforms, when the medium in the elastic bag 10 returns to the inside of the medium bag 4, the bottom position of the elastic bag 10 cannot extrude the threaded frame 61, and the threaded frame 61 resets under the elastic force of the U-shaped elastic sheet 74.

[0053] It should be noted that the elastic force of the U-shaped elastic sheet 74 is greater than the sum of the resistance of the threaded frame 61 and the threaded sleeve 62 and the frictional force between the scraping ring 71 and the outer wall of the drainage tube 1.

[0054] Specifically, as shown in Figures 2 to 6As shown, the outer top and bottom ends of the scraping ring 71 are inclined, the top bending part of the bent frame 72 is inclined, the bent frame 72 and the scraping ring 71 are made of latex material, the inner side of the bent frame 72 and the scraping ring 71 is fixedly connected with a rigid reinforcing rib 73, and the top of the bent frame 72 is fixedly connected with a third flexible film 75 between the inner wall of the drainage tube 1.

[0055] Through the above technical scheme, the outer top and bottom ends of the scraping ring 71 are inclined, the top bending part of the bent frame 72 is inclined, the bent frame 72 and the scraping ring 71 are made of latex material, the inner side of the bent frame 72 and the scraping ring 71 is fixedly connected with a rigid reinforcing rib 73, and the top of the bent frame 72 is fixedly connected with a third flexible film 75 between the inner wall of the drainage tube 1.

[0056] Specifically, as shown in the figure, Figures 2 to 6 As shown, the inside of the communication pipe 5 near the medium bag 4 is provided with a slow flow assembly 8, the slow flow assembly 8 includes a circular plate 81 fixedly connected inside the communication pipe 5 near the medium bag 4, the middle part of the circular plate 81 is provided with a through slot 82, the right side wall of the circular plate 81 is fixedly connected with an elastic stop sheet 83, the length of the elastic stop sheet 83 is less than the height of the through slot 82, and the inside of the medium bag 4 is provided with a fluid medium, and the fluid medium is viscous in texture.

[0057] Through the above technical scheme, when the medium bag 4 is pressed, the medium in the communication pipe 5 flows to the direction of the elastic bag 10, under the action of the flow pressure of the liquid medium, the elastic stop sheet 83 deviates to the direction of the circular plate 81, the elastic stop sheet 83 is attached to the circular plate 81, thereby blocking most of the through slot 82, slowing down the speed of the liquid medium, thereby avoiding the speed of the elastic bag 10 from being too fast when the medium bag 4 is pressed, so as to further improve the comfort of the device in use.

[0058] Working principle: the liquid injection bottle 2 is hung on the external hook through the fixing ring, and when in use, a liquid pump can be installed at the position of the flushing pipe 3 close to the liquid injection bottle 2 to adjust the flow rate and pressure of the physiological saline in the flushing drainage tube 1, and the bottom of the drainage tube 1 can be connected with a negative pressure suction device for providing negative pressure to the inside of the drainage tube 1, so that abdominal cavity drainage can be smoothly carried out.

[0059] When the drainage is carried out, if the blockage occurs, the medium bag 4 needs to be pressed constantly, when the medium bag 4 is pressed, the viscous medium in the medium bag 4 enters the inside of the communication pipe 5, and the medium flows in the communication pipe 5 and enters the inside of the elastic bag 10, when the hand is released, under the elastic force of the elastic bag 10 itself, the medium returns to the inside of the medium bag 4 through the communication pipe 5, therefore, when the medium bag 4 is pressed constantly, the elastic bag 10 constantly shrinks and expands, so that the liquid in the inside of the drainage tube 1 can be oscillated to eliminate the blockage problem of the drainage tube 1, and the purpose of unobstructed drainage is finally realized.

[0060] When the elastic bag 10 expands, the bottom part of the elastic bag 10 extrudes the screw frame 61, so that the screw frame 61 moves downward, under the action of the screw connection, the screw sleeve 62 rotates, so that the stirring frame 63 rotates, when the stirring frame 63 stirs, the pus and pus moss can be stirred, so that the viscous pus and pus moss can be broken, and the effect of preventing the blockage of the abdominal cavity drainage is improved.

[0061] When the medium bag 4 is pressed, the medium in the communication pipe 5 flows from the direction of the medium bag 4 to the direction of the elastic bag 10, at this time, the micro liquid flow sensor 13 detects the liquid flow and transmits the signal to the external controller, and the controller controls the electromagnetic valve 9 to close, when the elastic bag 10 expands, the top opening of the drainage tube 1 is blocked, and the electromagnetic valve 9 is closed, at this time, the area close to the drainage hole 11 in the inside of the drainage tube 1 is in a closed state except the drainage hole 11, so when the elastic bag 10 continues to expand, the liquid in the inside of the drainage tube 1 flows from inside to outside through the drainage hole 11, so as to facilitate the dredging of the drainage hole 11, and the effect of preventing the blockage of the abdominal cavity drainage is further improved.

[0062] When the stirring frame 63 rotates, the relative movement occurs between the stirring frame 63 and the auxiliary plate 65 because the auxiliary plate 65 is fixed on the inner wall of the drainage tube 1, and the auxiliary plate 65 can pass through the inside of the groove 64 when the stirring frame 63 rotates, the auxiliary plate 65 can cooperate with the stirring frame 63 to improve the breaking effect of the viscous pus and pus moss when the stirring frame 63 rotates, and the effect of preventing the blockage of the abdominal cavity drainage is further improved.

[0063] When the medium enters the inside of the elastic bag 10, the screw frame 61 moves downward, so that the bending frame 72 moves downward, and then the plurality of scraping rings 71 move, so that the scraping rings 71 can scrape the place corresponding to the drainage hole 11 on the outer wall of the drainage tube 1, the effect of dredging the drainage hole 11 is further improved, and the effect of preventing the blockage of the abdominal cavity drainage is further improved.

[0064] The outer side top and bottom ends of the scraping ring 71 are both inclinedly arranged, the top bending part of the bending frame 72 is inclinedly arranged, the damage to the patient is reduced when the drainage tube 1 is inserted into the abdominal cavity, the comfort of the device is improved, the bending frame 72 and the scraping ring 71 are both made of latex material, the comfort of the device is further improved, the rigid reinforcing rib 73 is arranged, so that when the threaded frame 61 moves, the scraping ring 71 and the bending frame 72 can smoothly move to scrape the outer wall of the drainage tube 1, when the medium bag 4 is pressed, the medium in the communication pipe 5 flows to the direction of the elastic bag 10, under the action of the liquid medium flow pressure, the elastic baffle 83 deviates to the direction of the circular plate 81, the elastic baffle 83 is close to the circular plate 81, so as to block most of the through slot 82, slow down the speed of the liquid medium flow, so as to avoid the speed of pressing the medium bag 4 being too fast, the elastic bag 10 is inflated too fast, and the abdominal pressure of the patient is rapidly increased.

[0065] The technical features of the above embodiments can be combined in any manner (as long as the combination of the technical features does not exist contradiction), in order to make the description simple, not all possible combinations of the technical features in the above embodiments are described; these embodiments which are not explicitly written should also be considered as the scope of the present application.
