[0002] The main purpose of pericardial effusion drainage is to drain the abnormal accumulation of fluid in the pericardium out of the body to relieve the symptoms of cardiac compression and improve cardiac function. This is usually applicable to pericardial effusion caused by diseases such as pericarditis, heart failure, heart rupture and cardiac tamponade.

[0003] The existing cardiovascular fluid drainage device is equipped with multiple fluid tanks to store the drained fluid during the fluid drainage process. However, during the fluid drainage process, the effusion will be diverted to multiple fluid tanks at the same time. When the effusion content is small, the effusion cannot fully fill the internal space of the multiple fluid tanks, and may even only flood the bottom of the fluid tanks, thereby reducing the utilization rate of the fluid storage space of the fluid tanks. At the same time, it also increases the number of fluid tanks that need to be cleaned later, increasing the workload of cleaning staff.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0032] In one embodiment of the present invention, see Figure 1-Figure 3 and Fig.11A device for draining effusion in cardiovascular medicine comprises a shell 1, a slide rail 102 is arranged at the bottom of the shell 1, a moving assembly 3 is movably arranged in the shell 1, the moving assembly 3 comprises a storage box 301 which is slidably matched with the slide rail 102, a plurality of moving wheels 302 are symmetrically installed at the bottom of the storage box 301, two partitions 303 are distributed on the storage box 301, the two partitions 303 divide the storage space of the storage box 301 into three placement spaces for sequentially storing corresponding collection tanks 5, a gravity sensor (not shown) in contact with the bottom of the collection tank 5 is arranged in the placement space, and a storage box 301 is provided in the shell 1. A positioning component 6 that movably cooperates with the collecting tank 5, one end of the shell 1 is provided with a rear end opening, and an opening and closing component 2 that movably abuts against the positioning component 6 is provided at the rear end opening, a supporting component 10 that movably cooperates with the storage box 301 is provided at the bottom of one end of the shell 1 away from the closing component 2, a lifting component 7 that movably cooperates with the top of the collecting tank 5 is movably provided inside the shell 1, the lifting component 7 is connected to a suction component 8 provided inside the shell 1, and a switching component 9 is provided on the suction component 8, and a front end opening is provided at one end of the shell 1 away from the closing component 2, and an adjusting component 4 corresponding to the suction component 8 is provided at the front end opening.

[0033] In this embodiment, the front end opening of the shell 1 is opened by adjusting the component 4, and the cardiovascular effusion of the patient can be extracted in an orderly manner through the cooperation of the suction component 8 and the switching component 9. The extracted effusion will be orderly introduced into the three collecting tanks 5, so that all the effusion can be drained once, avoiding the disadvantage that the capacity of a single collecting tank 5 is insufficient to accommodate all the effusion and requires secondary drainage. After the drainage of the effusion is completed, the cooperative connection between the collecting tank 5 and the suction component 8 is released through the lifting component 7, and the rear end opening is opened through the opening and closing component 2. The bottom of the support component 10 contacts the ground to realize the positioning and support of the front end of the shell 1. At the same time, the support component 10 pushes the storage box 301 to move toward the rear end opening of the shell 1, and the storage box 301 drives several collecting tanks 5 to move outward, releasing the positioning component 6. The clamping operation of the three collecting tanks 5 facilitates the collection tank 5 to move outward, and the collection tank 5 containing the accumulated liquid can be taken out and replaced with a new collection tank 5 for the next use. The storage box 301 is pushed into the inside of the shell 1, and the storage box 301 drives the collection tank 5 placed thereon to move synchronously. The storage box 301 clamps the position of the collection tank 5 by movably abutting against the positioning component 6. At the same time, the storage box 301 releases the positioning of the front end of the shell 1 by movably contacting with the supporting component 10, and the opening and closing component 2 is closed to achieve relative locking of the storage box 301 and the shell 1. The shell 1 is driven to move by the moving wheel 302 to achieve flexible movement of the device position, which has the effects of effective dust prevention, orderly and stable drainage, flexible switching, automatic clamping and positioning, reliable structure, convenient operation, and simple and practical operation. Among them, the shell 1 is provided with a device for temporarily placing medical equipment or medicines, which avoids the inefficiency of medical staff holding the device. An abutment plate 103 is symmetrically installed on the bottom of the end of the shell 1 close to the rear end opening. The abutment plate 103 is movably abutted with a side ear 3011 arranged at the end of the storage box 301 away from the rear end opening, which can limit the moving distance of the storage box 301 and prevent the storage box 301 from sliding out of the range of the slide rail 102. A handle 104 is installed above the end of the rear end opening of the shell 1. The handle 104 makes it convenient for medical staff to push the device to move its position. Support bars 105 that slide with the positioning component 6 are symmetrically installed on the inner wall of the shell 1.

[0034] In one embodiment of the present invention, see Figure 1 and Figure 3 The opening and closing assembly 2 includes a movable door 201 hinged at the rear end opening, and a plurality of ventilation grooves 202 are provided on the movable door 201. A horizontal bar 203 located above the movable door 201 is installed on the shell 1, and a first limiting cam 204 that is rotatably abutted against the movable door 201 is provided on the horizontal bar 203.

[0035] In this embodiment, in the initial state, the movable door 201 cooperates with the rear end opening, and the outer end of the first limit cam 204 abuts against the outer surface of the movable door 201, so that the position of the movable door 201 can be fixed, thereby realizing the closure of the internal space of the shell 1 and preventing external dust from entering the interior of the shell 1. When the rear end opening needs to be opened, the first limit cam 204 is rotated 180 degrees clockwise or counterclockwise around the cross bar 203, so that the outer end of the first limit cam 204 is away from the movable door 201, and the positioning of the movable door 201 is released. The positioning component 6 pushes the movable door 201 to rotate outward by abutting against the inner side of the movable door 201, thereby realizing the opening of the rear end opening and facilitating the export of the storage box 301. Among them, through a plurality of air permeable grooves 202, the export of the internal gas of the shell 1 is facilitated.

[0036] In one embodiment of the present invention, see Figure 1-Figure 5The positioning assembly 6 includes a limit plate 601 symmetrically and movably arranged inside the housing 1. The limit plate 601 is provided with a plurality of positioning grooves 602 movably abutting against the outer wall of the collection tank 5 on one side thereof close to the collection tank 5. The limit plate 601 is provided with at least two second rotating rods 604 movably at one end thereof away from the collection tank 5. One end of the second rotating rod 604 is rotatably connected to the inner wall of the housing 1. One end of the second rotating rod 604 is provided with a spiral strip 6041 slidably matched with the limit plate 601. The second rotating rod 604 is provided with a spiral strip 6041 slidably matched with the limit plate 601. A first transmission gear 603 is installed on the rod 604, and a movable frame 605 is slidably provided inside the outer shell 1. The movable frame 605 is set as a U-shaped plate. A rack 6051 meshing with the corresponding first transmission gear 603 is provided on the movable frame 605. A cross bar 606 is symmetrically provided at one end of the outer shell 1 away from the closing component 2. The cross bar 606 is slidably matched with the movable frame 605. A first spring 607 mounted on the outside of the cross bar 606 is connected between the movable frame 605 and the inner wall of the outer shell 1.

[0037] In this embodiment, in the initial state, the ends of the symmetrically arranged limit plates 601 are in active contact with the inner side wall of the movable door 201, and the first spring 607 is in a state of contraction under force. At this time, the symmetrically arranged limit plates 601 are in a state of being close to each other, and the three collection tanks 5 can be clamped and positioned accordingly through the positioning grooves 602; When it is necessary to take out the collecting tank 5, the first limiting cam 204 is rotated 180 degrees clockwise or counterclockwise around the cross bar 203, so that the outer end of the first limiting cam 204 is away from the movable door 201, the positioning of the movable door 201 is released, and the first spring 607 is extended and pushes the movable frame 605 to move outward by sliding cooperation between the movable frame 605 and the cross bar 606. The end of the movable frame 605 pushes the movable door 201 to rotate outward by movably contacting with the inner wall of the movable door 201, so that the movable door 201 automatically rotates outward. At the same time, the movable frame 605 drives the rack 6051 to move synchronously, and the rack 60 51 drives the second rotating rod 604 to rotate by meshing with the first transmission gear 603, and the second rotating rod 604 drives the symmetrically arranged limiting plates 601 to move away from each other by sliding cooperation with the limiting plates 601 through the spiral strip 6041, releases the positioning and clamping of the collection tank 5, and pulls the storage box 301 outward. The storage box 301 moves outward with the help of the moving wheel 302. When the side ear 3011 fits with the abutment plate 103, the storage box 301 stops moving. At this time, the moving distance of the storage box 301 reaches the maximum value, which is convenient for taking out the collection tank 5 containing the accumulated liquid and replacing the new collection tank 5 for subsequent operations; The positioning groove 602 is configured as a V-shaped groove. Through the symmetrically arranged positioning grooves 602 , the corresponding collecting tank 5 can be clamped at four points, thereby improving the stability of the positioning of the collecting tank 5 .

[0043] The switching assembly 9 includes a third rotating rod 901 rotatably arranged in the drainage tank 802 and the air inlet tank 803 respectively, and a switching disk 908 connected to the corresponding third rotating rod 901 is rotatably arranged at the bottom of the inner side of the drainage tank 802 and the air inlet tank 803, and a groove 9081 corresponding to only one guide hole 8021 or the air guide hole 8031 ​​is opened on the switching disk 908. The end of the third rotating rod 901 away from the switching disk 908 penetrates the drainage tank 802 or the air inlet tank 803 and is connected to the second transmission gear 90 2, a guide plate 904 is slidably provided on the fixed plate 801, an adjusting rack frame 903 located between the two second transmission gears 902 is installed on the guide plate 904, the adjusting rack frame 903 is respectively meshed with the second transmission gears 902 on both sides, a tooth groove 905 is provided on the guide plate 904, a rotating gear 906 meshing with the tooth groove 905 is rotatably provided on the fixed plate 801, and the rotating gear 906 is connected to a rotating motor 907 installed on the fixed plate 801.

[0044] In this embodiment, in the initial state, the groove 9081 located in the drainage tank 802 corresponds to one of the flow guide holes 8021, and the groove 9081 located in the air guide tank 803 corresponds to one of the air guide holes 8031. The flow guide hole 8021 and the air guide hole 8031 ​​both correspond to the same sealing cover 705, that is, the flow guide hole 8021 and the air guide hole 8031 ​​both correspond to the same collection tank 5; When drainage of the effusion is required, the rotary motor 907 does not work, the air pump 808 works and extracts the air inside the corresponding collection tank 5 through the connection of the exhaust pipe 807, the air inlet tank 803 and the corresponding air inlet pipe 806, the air pressure inside the corresponding collection tank 5 is reduced, and the effusion is negatively sucked into the drainage tank 802 through the drainage pipe 805, and then flows into the corresponding collection tank 5 through the corresponding guide hole 8021 and the corresponding liquid guide pipe 804, thereby realizing negative pressure suction treatment of the effusion; When the amount of accumulated liquid in the collection tank 5 reaches a certain range, the vacuum pump 808 stops working, the rotating motor 907 starts working and drives the rotating gear 906 to rotate forward for a certain number of circles. The rotating gear 906 drives the adjusting rack frame 903 to move a certain distance by meshing with the tooth groove 905 and the sliding cooperation between the guide plate 904 and the fixed plate 801. The adjusting rack frame 903 drives the third rotating rod 901 to rotate the shell 1 opening and closing component 20 degrees by meshing with the second transmission gears 902 on both sides. The third rotating rod 901 drives the switching disk 908 to rotate synchronously. The groove 9081 corresponds to another guide hole 8021 or the air guide hole 8031, and then the rotating motor 907 stops working and the air pump 808 starts working again, so that the accumulated liquid in another collection tank 5 can be collected, and the accumulated liquid can be collected in an orderly manner, so that the accumulated liquid is not drained into multiple collection tanks 5 at the same time and the storage space inside the collection tank 5 cannot be fully utilized. For different amounts of accumulated liquid, the accumulated liquid can be stored in stages, so that when the amount of accumulated liquid is small and is drained into multiple collection tanks 5 respectively, the multiple collection tanks 5 need to be cleaned later. The number of revolutions of the rotating gear 906 is determined by the actual number of teeth of the second transmission gear 902, the actual number of teeth of the adjusting rack frame 903 and the actual number of teeth of the tooth groove 905. When the amount of accumulated liquid in the collecting tank 5 is measured, it can be determined by a weight sensor arranged at the bottom of the collecting tank 5. When the pressure on the weight sensor reaches the set range value, the signal is transmitted to the control module (not shown in the figure) inside the housing 1. The control module controls the corresponding start and stop of the lifting motor 704, the suction pump 808 and the rotating motor 907, which is convenient for the flexible switching of the collecting tank 5, can meet the orderly drainage of the accumulated liquid, improve the utilization rate of the liquid storage space of the collecting tank 5, and reduce the subsequent processing operations of the collecting tank 5. The top of the switching disk 908 is provided with an inclined surface to facilitate the rapid diversion of the accumulated fluid.

[0045] In one embodiment of the present invention, see Figure 1-Figure 3 , Figure 7 and Fig.10The adjustment component 4 includes a movable plate 401 hinged at the front end opening of the shell 1, and a buckle 402 movably engaged with the drainage tube 805 is installed on a side wall of the movable plate 401 close to the inside of the shell 1, and a fixed arc plate 4011 is provided on the top of the side of the movable plate 401 close to the buckle 402. A first rotating rod 403 located above the movable plate 401 is rotatably provided on the shell 1, and one end of the first rotating rod 403 is connected to a second limiting cam 404 movably abutted against the outer wall of the movable plate 401, and the other end of the first rotating rod 403 is connected to a rotating disk 405 movably provided inside the shell 1, and a movable arc plate 4051 movably contacting with the fixed arc plate 4011 is provided on the side of the rotating disk 405 close to the second limiting cam 404.

[0046] In this embodiment, in the initial state, the outer end of the second limit cam 404 is vertically downwardly arranged and abuts against the outer wall of the movable plate 401, and the movable arc plate 4051 is away from the fixed arc plate 4011. At this time, the movable plate 401 is matched with the front end opening of the housing 1, and the drainage tube 805 is engaged with the buckle 402; When it is necessary to drain the effusion, the second limiting cam 404 is rotated upward to release the contact between the outer end of the second limiting cam 404 and the outer side of the movable plate 401. At the same time, the second limiting cam 404 drives the rotating disk 405 to rotate synchronously through the first rotating rod 403. When the second limiting cam 404 rotates 180 degrees upward, the rotating disk 405 rotates 180 degrees downward. The rotating disk 405 drives the movable arc plate 4051 to rotate synchronously and the movable arc plate 4051 and the fixed arc plate 4011 are movably abutted to push the movable plate 401 outward, so as to realize the outward turning of the movable plate 401, which is convenient for the conduction of the front end opening of the shell 1. The buckle 402 is pulled outward to release the clamping connection between the drainage tube 805 and the buckle 402, so that the medical staff can take out the drainage tube 805 and realize the drainage treatment of the effusion. During this period, the outer end of the second limiting cam 404 will automatically rotate downward under the action of its own gravity, so that the outer end of the second limiting cam 404 is located at the lower end. After the drainage of the effusion is completed, the second limiting cam 404 is rotated 180 degrees upward around the first rotating rod 403, the drainage tube 805 is re-engaged on the buckle 402, and the movable plate 401 is pushed to rotate upward, so that the movable plate 401 is matched with the front end opening of the shell 1 again, and then the second limiting cam 404 is released, and the outer end of the second limiting cam 404 automatically rotates downward under the action of its own gravity, so that the second limiting cam 404 is in contact with the outer wall of the movable plate 401 again, so that the positioning of the movable plate 401 can be achieved; The movable plate 401 is provided to facilitate storage and dust prevention of the drainage tube 805 when no drainage operation is performed, which can effectively prevent the drainage tube 805 from being exposed to the external environment for a long time and being damaged by scratches and dust accumulation; Among them, both ends of the movable arc plate 4051 and the fixed arc plate 4011 are provided with contact inclined surfaces 10051, and the contact inclined surfaces 10051 are provided to facilitate smooth contact between the fixed arc plate 4011 and the movable arc plate 4051, thereby avoiding the movable arc plate 4051 and the fixed arc plate 4011 from getting stuck.
