Description

Technical Field

[0001] The present invention relates to the technical field of fluid drainage, and in particular to a device and method for fluid drainage in cardiovascular medicine. Background Art

[0002] Cardiovascular medicine is a clinical department set up by the internal medicine department of hospitals at all levels to diagnose and treat cardiovascular diseases. The diseases treated include angina pectoris, hypertension, sudden death, arrhythmia, heart failure, premature beats, arrhythmia, myocardial infarction, cardiomyopathy, myocarditis, myocardial infarction and other cardiovascular diseases. Drainage is one of the commonly used surgical methods in cardiovascular medicine, which is to drain the fluid and blood accumulated in the patient's cavity or subcutaneous tissue out of the body.

[0003] In the treatment of cardiovascular diseases, drainage equipment is an indispensable treatment device, which plays an important role in draining the body fluids accumulated under the skin or in the cavity of the patient out of the body. However, the drainage equipment currently used generally only adopts a simple gravity drainage method. The drainage tube is often blocked during the drainage process. The drainage equipment is not easy to disassemble, clean and disinfect, which brings great inconvenience to medical staff and patients.

[0004] In order to avoid the above problems, in view of this: Chinese patent CN215134111U discloses a fluid drainage device for cardiovascular medicine, including a bottom plate, a box body is arranged on the top of the bottom plate, a support plate is arranged horizontally at the lower part of the inner cavity of the box body, the left and right ends of the support plate are slidably connected to the inner wall of the box body, a return spring is arranged between the left part of the bottom end of the support plate and the bottom wall of the box body, and a lifting mechanism is arranged between the right part of the bottom end of the support plate and the bottom wall of the box body. The utility model can facilitate the replacement of the fluid bottle through the support plate, return spring, bottle cap and other structures, and can make the fluid bottle close to the bottle cap during drainage work through the lifting mechanism to maintain the sealing of the connection. This scheme uses a vacuum pump to make the fluid bottle have a negative pressure to improve the drainage efficiency and effectively avoid the problem of pipeline blockage. The ultraviolet sterilization lamp can be used to sterilize and disinfect the box body, and the filter cartridge can be used to purify and adsorb the discharged gas.

[0005] Although the above can improve the drainage efficiency and avoid blockage, it is inevitable that there are still some shortcomings in the actual use process. For example, the device lacks a centering adjustment mechanism, so that during the fitting of the effusion bottle and the bottle cap, there will be a problem of inconvenience in sealing due to the non-centering, and the drainage tube lacks a convenient storage mechanism, which leads to the drainage tube being exposed and covered with dust when the device is not in use.

[0015] The present invention also discloses a method for draining effusion in cardiovascular medicine, which specifically comprises the following steps:

[0016] S1. Open the box door and place the liquid accumulation bottle on the top of the lifting platform, then start the servo motor, the servo motor starts to drive the threaded rod to rotate, the threaded rod rotates the threaded sleeve on its surface to drive the lifting platform and the ladder frame to rise, and the rising of several ladder frames will be squeezed and gathered with the gathering ring fixed inside the installation box, and the ladder frame will be squeezed and moved to drive the installation frame and the positioning guide roller to move closer to the bottle body until the positioning guide roller fits with the bottle body, and the liquid accumulation bottle is gathered by multiple installation frames and positioning guide rollers, and will be centered just below the bottle cap until the liquid accumulation bottle and the bottle cap are sealed and fit;

[0017] S2. While the ladder frames gather and rise synchronously, the ladder frame on the left synchronously squeezes the L-shaped movable plate to move to the right through the squeezing roller assembly, and the L-shaped movable plate drives the tripod and the storage roller assembly to move to the right. The rightward movement of the storage roller assembly will loosen the transfer hose for the first time, and the corresponding tripod will synchronously drive the wave lifting plate to move to the right along with the movement of the L-shaped movable plate. The rightward movement of the wave lifting plate will lift the sliding roller for the first lifting, causing the upper drainage pipe to rise and approach the bottom of the shielding plate. The corresponding rise of the upper drainage pipe will tighten the loose transfer hose again;

[0018] The L-shaped movable plate moves to the right, synchronously driving the tooth limit block to move, and causing the tooth limit block to mesh with the first gear. When the tooth limit block meshes with the first gear, the shield plate moves in the opposite direction to the L-shaped movable plate, thereby reserving a protruding space for the upper drainage pipe.

[0019] As the left ladder frame and the squeezing roller assembly continue to rise, the squeezing roller assembly will contact the tripod and squeeze the tripod, prompting the tripod to carry the storage roller assembly to continue to relax the transfer hose for the second time. When the tripod carries the storage roller assembly to move right again, the tripod synchronously drives the wave lifting plate to lift the sliding roller for the second time. The rising sliding roller drives the upper drainage pipe to extend from the inside of the installation box to the top of the installation box.

[0020] Finally, the external drainage hose is manually connected to the extended end of the upper drainage tube, and then the vacuum pump is started to extract the effusion in the human lesion under negative pressure;

[0021] S3. During the period when the threaded sleeve carries the lifting platform and the liquid accumulation bottle to rise, the lifting platform synchronously drives the second tooth plate to rise, the second tooth plate rises and meshes with the second gear, and the second gear synchronously meshes with the first tooth plate in the opposite direction, so that the first tooth plate carries the support pad to form a fixed support with the ground, thereby stably placing the installation box as a whole.

[0022] Preferably, both sides of the bottom of the installation box in S3 are provided with driving grooves matched with the first tooth plate and the second tooth plate. Beneficial Effects

[0023] The present invention provides a device and method for drainage of effusion in cardiovascular medicine. Compared with the existing technology, it has the following beneficial effects:

[0024] (1) The cardiovascular internal medicine effusion drainage device and drainage method, by arranging a centering adjustment mechanism, a storage mechanism and a self-stabilizing mechanism between the installation box, the lifting platform, the effusion bottle, the bottle cap and the suction mechanism, enables the device to calibrate and seal the effusion bottle and the bottle cap through the coordinated cooperation of the centering adjustment mechanism, the storage mechanism and the self-stabilizing mechanism, and simultaneously make corresponding extension and shielding storage of the upper drainage tube in the use state to avoid the problem of exposure and dust when it is not in use, and simultaneously make automatic stable placement cooperation for the device that stops moving, thereby improving the convenience of using the device.

[0025] (2) The cardiovascular internal medicine effusion drainage device and drainage method, by arranging a reset slide groove, a reset slider and a third reset spring matched with the ladder frame on the top of the lifting platform, the ladder frame can be easily reset, so that after the effusion bottle and the bottle cap are out of sealing, the ladder frame can be reset to reserve a space around the effusion bottle for taking out, so as to facilitate the subsequent taking out of the effusion bottle.

[0026] (3) The cardiovascular internal medicine effusion drainage device and drainage method are provided with guide grooves and guide sliders on both sides of the inner cavity of the installation box, which are used in conjunction with the lifting platform. When the threaded rod and the threaded sleeve are matched through threads, the lifting platform can be driven to rise. The sliding limit of the guide groove and the guide slider can provide stable guidance for the lifting platform, thereby improving the stability of the lifting platform.

[0027] (4) The cardiovascular internal medicine effusion drainage device and drainage method are provided with a first slide plate, a limit slide plate and a first return spring on the rear side of the installation box, which are used in conjunction with the L-shaped movable plate. The L-shaped movable plate can be easily engaged and reset with the shield plate through the elastic cooperation of the first slide plate, the limit slide plate and the first return spring, so that the shield plate can perform corresponding opening and closing actions in different use states.

[0047] S1. Open the box door and place the liquid accumulation bottle 3 on the top of the lifting platform 2, then start the servo motor 605. The servo motor 605 starts to drive the threaded rod 606 to rotate. The threaded rod 606 rotates the threaded sleeve 607 on its surface to drive the lifting platform 2 and the ladder frame 601 to rise. The rising of several ladder frames 601 will squeeze and gather with the gathering ring 604 fixed inside the installation box 1. The ladder frame 601 is squeezed and moved to drive the installation frame 602 and the positioning guide roller 603 to move closer to the bottle body until the positioning guide roller 603 fits with the bottle body. The liquid accumulation bottle 3 is gathered by multiple installation frames 602 and positioning guide rollers 603 and will be centered directly below the bottle cap 4 until the liquid accumulation bottle 3 and the bottle cap 4 are sealed and fit;

[0048] S2, while the ladder frame 601 gathers and rises synchronously, the left ladder frame 601 synchronously squeezes the L-shaped movable plate 701 to move to the right through the squeezing roller assembly 704, and the L-shaped movable plate 701 drives the tripod 702 and the storage roller assembly 703 to move to the right, and the rightward movement of the storage roller assembly 703 will loosen the transfer hose 505 for the first time, and the corresponding tripod 702 synchronously drives the wave lifting plate 705 to move to the right along with the movement of the L-shaped movable plate 701, and the rightward movement of the wave lifting plate 705 will lift the sliding roller 707 for the first time, so that the upper drainage tube 504 rises and approaches the bottom of the shielding plate 709, and the corresponding rise of the upper drainage tube 504 will tighten the loose transfer hose 505 again;

[0049] The L-shaped movable plate 701 moves to the right and synchronously drives the tooth limit block 710 to move, and causes the tooth limit block 710 to mesh with the first gear 711. When the tooth limit block 710 meshes with the first gear 711, the shielding plate 709 moves in the opposite direction to the L-shaped movable plate 701, and reserves a space for the upper drainage pipe 504 to extend.

[0050] As the left ladder frame 601 and the squeezing roller assembly 704 continue to rise, the squeezing roller assembly 704 will contact the tripod 702 and squeeze the tripod 702, prompting the tripod 702 to carry the storage roller assembly 703 to continue to relax the transfer hose 505 for the second time.

[0052] S3, while the threaded sleeve 607 carries the lifting platform 2 and the liquid collection bottle 3 to rise, the lifting platform 2 synchronously drives the second tooth plate 805 to rise, and the second tooth plate 805 rises and meshes with the second gear 804, and the second gear 804 synchronously meshes with the first tooth plate 803 in the opposite direction, so that the first tooth plate 803 carries the support pad 806 to form a fixed support with the ground, thereby stably placing the installation box 1 as a whole, wherein both sides of the bottom of the installation box 1 are provided with driving grooves for matching with the first tooth plate 803 and the second tooth plate 805.
