Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically to a pleural effusion drainage and extraction device for cardiology and its usage method. Background Art

[0002] Pleural effusion refers to the pathological state in which fluid abnormally accumulates in the pleural cavity. The pleural cavity is a potential cavity with a small amount of fluid inside, which plays a role in lubricating and protecting the lungs. Under normal circumstances, the fluid in the pleural cavity is in a dynamic balance state. However, certain diseases or conditions can break this balance. When the generation and absorption of fluid are out of balance, pleural effusion will be formed. A pleural effusion drainage and extraction device is a medical device that discharges the effusion or gas in the pleural cavity to the outside by connecting a drainage tube in the pleural cavity with an external drainage device. Through this device, on the one hand, the effusion or gas in the pleural cavity can be continuously or intermittently discharged according to the patient's condition to relieve the patient's pain. On the other hand, the drained fluid can be collected to facilitate doctors or nurses to observe the volume, color, and properties (such as thickness) of the drained effusion, and adjust the drainage speed and negative pressure as needed, or collect and analyze the drained effusion for laboratory tests. The principle of the pleural effusion drainage and extraction device for discharging fluid is to squeeze the fluid inside the pleural cavity through a single external channel of the drainage tube and the pressure generated by breathing and coughing in the pleural cavity. In the pleural effusion drainage and extraction device, when the drainage bottle is full and needs to be replaced, medical staff will use tools such as hemostatic forceps to firmly clamp the drainage tube to prevent the backflow of gas or fluid. After replacing the new drainage bottle, the hemostatic forceps are then opened to continue the drainage. If the drainage tube is not clamped, the gas or residual fluid in the pleural cavity may flow back into the pleural cavity through the drainage tube, resulting in the occurrence of pneumothorax, infection, or other complications. Therefore, during the process of replacing the drainage bottle, clamping the drainage tube can ensure the safety during the replacement process. In winter or when the external temperature is relatively low, due to the low-temperature environment, the material of the drainage tube becomes hard and its toughness decreases. After the drainage tube is flattened by external force, its ability to return to its original shape weakens. In this case, the drainage tube cannot fully return to its original shape due to insufficient elasticity, resulting in creases on the inner wall. The presence of creases will narrow or deform the internal channel of the drainage tube, increasing the flow resistance of the fluid. When some relatively viscous pleural effusions pass through the crease, the drainage will be unsmooth or completely blocked, affecting the normal discharge of the effusion. Therefore, in view of the above problems, a pleural effusion drainage and extraction device for cardiology and its usage method are proposed. Summary of the Invention

[0003] The object of the present invention is to provide a drainage and extraction device for pleural effusion in the department of cardiology and its usage method, so as to solve the problem that in a low-temperature environment, the material of the drainage tube becomes hard and its toughness decreases, and the ability of the drainage tube to return to its original state after being pinched flat by an external force weakens. In this case, the drainage tube cannot fully return to its original state due to insufficient elasticity, resulting in creases on the inner wall. The presence of the creases will narrow or deform the internal channel of the drainage tube, increasing the flow resistance of the fluid.

[0008] As a further optimized content of the present invention, wherein: the inner wall reset support assembly includes an elastic hose, a cavity is provided inside the elastic hose, 5 ml of 0.9% sodium chloride solution is injected into the cavity inside the elastic hose, two groups of spring strip assemblies are fixedly installed inside the elastic hose and are symmetrically distributed up and down, there is a gap between the two groups of spring strip assemblies, each group of spring strip assemblies has several, and a plurality of the spring strip assemblies are annularly arrayed inside the elastic hose, and a sliding assembly is slidably connected to the outside of the spring strip assembly.

[0009] As a further optimized content of the present invention, wherein: the materials of the grooved tube and the magnetic connection block are both alnico alloy, the position of the grooved tube corresponds to the position of the magnetic inner through tube one by one, and the height of the grooved tube is the same as the height of the magnetic inner through tube and is on the same horizontal plane.

[0010] As a further optimized content of the present invention, wherein: the spring strip assembly includes a spring strip body, the projection of the spring strip body in the vertical direction is arc-shaped, a particle is fixedly connected to one side of the spring strip body, the materials of the spring strip body and the particle are both 316 stainless steel, a chuck is fixedly connected to the inside of the spring strip body, and an arc angle is provided at one end of the spring strip body.

[0011] As a further optimized content of the present invention, wherein: the sliding assembly includes a grooved magnetic ring, the outside of the grooved magnetic ring is closely attached to the inside of the elastic hose, a limit sliding groove is provided inside the grooved magnetic ring, and the cross-sectional area of the limit sliding groove is 1.2 times the cross-sectional area of the spring strip body.

[0012] As a further optimized content of the present invention, wherein: the material of the grooved magnetic ring is samarium cobalt magnet, there are two grooved magnetic rings, the two grooved magnetic rings are symmetrically distributed up and down and the magnetism between them is repulsive, and the grooved magnetic ring and the magnetic sleeve ring are magnetically attractive.

[0013] As a further optimized content of the present invention, wherein: it includes the following steps: S1: Selection of the bending position of the drainage tube: When replacing the drainage bottle of this cardiology pleural effusion drainage and extraction device, a comprehensive evaluation of spatial factors is carried out according to the length of the drainage tube and the height of the hospital bed. According to the evaluation results, the approximate position of the bending and clamping of the drainage tube is determined. The outer support tube assembly is moved to change the relative position between the outer support tube assembly and the drainage tube. When the outer support tube assembly moves, the grooved tube drives the magnetic inner through tube to move through magnetic suction; When the magnetic inner through tube moves, the connecting sliding tube assembly drives the tube head assembly and the inner wall reset support assembly to move, changing the relative position between the inner support tube assembly and the drainage tube, so that the outer support tube assembly and the inner support tube assembly move to the corresponding positions where the drainage tube needs to be bent and clamped at the same time; S2: Bending and fixing the outer support tube assembly to complete the clamping of the drainage tube: While passing one finger through the pull ring, bend the outer support tube assembly with the other two fingers. When the outer support tube assembly is bent to a certain extent, the magnetic connection blocks located on one side of the upper and lower grooved tubes will be adsorbed under the mutual action of their magnetic forces. The airbag blocks arranged in the block slots correspondingly opened in the two mutually adsorbed magnetic connection blocks are squeezed. At the same time, two fingers press the airbag blocks arranged in the block slots correspondingly opened in the two non-mutually adsorbed magnetic connection blocks. The four airbag blocks are squeezed at the same time, and the four airbag blocks exhaust air into the gap between the inner limiting tube and the outer limiting tube through the corresponding air holes and the inter-tube air grooves at the same time, so that the sliding tube is pushed. The sliding tube squeezes the corrugated hose, causing the corrugated hose to fold, and at the same time completing the clamping of the drainage tube; S3: Release and rapid recovery of the drainage tube clamping: After the replacement of the drainage bottle of this cardiology pleural effusion drainage and extraction device is completed, pull the drainage tube to separate the two mutually adsorbed magnetic connection blocks. The corrugated hose and the drainage tube return to their deformed states at the same time, and the effusion circulates in the drainage tube again; S4: The inner support tube assembly assists the drainage tube to recover its deformation: When the drainage tube recovers from the bent state, the elastic hose recovers from the bent state and releases elastic potential energy to provide a support pressure to the inner wall of the drainage tube. At the same time, the spring strip assembly returns to its original state. By pulling the pull ring with fingers, the pull ring drives the nylon rope mesh sleeve and the magnetic sleeve ring to move. When the magnetic sleeve ring moves, the suction force generated by the magnetic sleeve ring on the grooved magnetic ring will drive the grooved magnetic ring to slide outside the spring strip body. When the particles pass through the limiting sliding groove, the friction between the particles and the grooved magnetic ring causes the spring strip body to vibrate and drives the elastic hose to vibrate. The vibration of the elastic hose generates a force on the inner wall of the drainage tube to make the drainage tube recover its deformation.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In the present invention, by providing the outer support tube assembly and the inner support tube assembly, the anti-deformation ability and self-recovery performance of the drainage tube under low-temperature conditions are improved, effectively addressing the problem of creases remaining after clamping caused by the hardening of the drainage tube in a low-temperature environment, ensuring the elastic recovery of the drainage tube and the smooth flow of the internal liquid and gas, reducing the risk of blockage of the internal liquid caused by the untimely recovery of the drainage tube, and providing a more reliable guarantee for the treatment of patients. 2. In the present invention, by providing the outer support tube assembly and the ring sleeve assembly, the operation logic of replacing the traditional drainage bottle is reconstructed, and the replacement process is simplified into a standardized action that can be completed with one hand, greatly reducing the risk of operation errors. This mechanism not only simplifies the operation process, reduces the operation time, but also effectively avoids complications such as pneumothorax and infection caused by improper clamping, improving the clinical safety and operation convenience. 3. In the present invention, by providing the ring sleeve assembly and the inner support tube assembly, the deformation recovery of the drainage tube is strengthened. Both by generating vibration through friction to accelerate the shape recovery of the drainage tube and by heat conduction to improve the flexibility of the drainage tube material, the problem of the decrease in the elastic modulus of the drainage tube caused by low temperature is fundamentally solved, and the problem of lumen stenosis caused by residual creases on the inner wall of the drainage tube is completely avoided.

[0021] Please refer to Figures 1-14 , a pleural effusion drainage and extraction device for cardiology and its usage method, including a drainage bottle 1 and a drainage tube 2. An outer support tube assembly 3 is sleeved outside the drainage tube 2, a ring sleeve assembly 4 is sleeved outside the outer support tube assembly 3, and an inner support tube assembly 5 is arranged inside the drainage tube 2. The outer support tube assembly 3 includes a magnetic attraction fixing unit 31. One end of the magnetic attraction fixing unit 31 is fixedly connected to an outer limiting tube 32. An inner limiting tube 33 is arranged inside the outer limiting tube 32. A sliding tube 34 is slidably connected to the outside of the inner limiting tube 33. The upper and lower ends of the inner limiting tube 33 are respectively fixedly connected to the magnetic attraction fixing unit 31 and a corrugated hose 35. The ring sleeve assembly 4 includes two magnetically conductive sleeve rings 41 distributed symmetrically up and down. A nylon rope mesh sleeve 42 is fixedly connected between the two magnetically conductive sleeve rings 41. A pull ring 43 is fixedly connected through the nylon rope mesh sleeve 42. The inner support tube assembly 5 includes a tube head assembly 51. One end of the tube head assembly 51 is fixedly connected to a connecting sliding tube assembly 52. The end of the connecting sliding tube assembly 52 away from the tube head assembly 51 is fixedly connected to an inner wall reset support assembly 53 by bonding. The ring sleeve assembly 4 is used to assist in bending the outer support tube assembly 3 and the drainage tube 2, facilitating the operation of medical staff. The magnetic attraction force generated by the magnetic attraction fixing unit 31 causes the inner support tube assembly 5 to bend and restricts the drainage tube 2 from restoring deformation, ensuring that the drainage tube 2 will not easily move or fall off during use.

[0022] Please refer to Figures 2-11 , in this embodiment, the tube head assembly 51 includes a reducing tube 511. One end of the reducing tube 511 is fixedly connected to a sealing ring 512. A plurality of swirling strips 513 distributed in a circular array are arranged inside the reducing tube 511. The diameter of the end of the reducing tube 511 fixedly connected to the sealing ring 512 is 0.9 times the diameter of the other end of the reducing tube 511. The connecting sliding tube assembly 52 includes a magnetically conductive inner through tube 521. One end of the magnetically conductive inner through tube 521 is provided with a connecting installation groove 522. A rolling installation groove 523 is opened inside the magnetically conductive inner through tube 521. A ball 524 is installed inside the rolling installation groove 523. The diameter of the ball 524 is 1.1 times the depth of the rolling installation groove 523. The material of the magnetically conductive inner through tube 521 is alnico alloy, and the material of the ball 524 is austenitic stainless steel.

[0023] Specifically, when the outer support tube assembly 3 moves, the magnetic attraction fixing unit 31 drives the magnetic inner through tube 521 to move through magnetic attraction. The balls 524 installed in the rolling installation groove 523 are used to reduce the friction between the magnetic inner through tube 521 and the drainage tube 2 and improve the sliding performance. The material of the balls 524 is austenitic stainless steel, which has good corrosion resistance, wear resistance and mechanical strength, and can ensure its rolling effect. When the magnetic inner through tube 521 moves, the connecting sliding tube assembly 52 will drive the tube head assembly 51 to move at the same time. The setting of the reducing pipe 511 reduces the contact area between it and the drainage tube 2 and reduces the friction. The outer side of the sealing ring 512 is arc-shaped, which can also make the sealing ring 512 slide better in the drainage tube 2. In this way, the user comprehensively evaluates various spatial factors such as the sleeping position of the patient and the height of the hospital bed, and changes the relative position between the outer support tube assembly 3 and the drainage tube 2 by moving the outer support tube assembly 3, which is convenient for subsequent clamping of the drainage tube 2. In addition, the setting of the swirl strip 513 enables the liquid flowing through the reducing pipe 511 to guide the drainage liquid or gas to generate rotational flow, thereby improving the drainage efficiency, preventing blockage and reducing the retention of liquid in the tube.

[0024] Please refer to Figures 1-11 , in this embodiment, the magnetic attraction fixing unit 31 includes a grooved tube 311. An inter-tube air groove 312 is formed inside the grooved tube 311. Two symmetrically distributed magnetic connection blocks 313 are fixedly connected to the outside of the grooved tube 311. An inter-block groove 314 is formed inside the magnetic connection block 313. An airbag block 315 is arranged inside the inter-block groove 314. An air hole 316 is formed on one side of the airbag block 315. An airbag block 315 is fixedly connected to one side of the grooved tube 311. The materials of the grooved tube 311 and the magnetic connection blocks 313 are both alnico alloy. The position of the grooved tube 311 corresponds to the position of the magnetic inner through tube 521 one by one. The height of the grooved tube 311 is the same as that of the magnetic inner through tube 521 and they are on the same horizontal plane.

[0025] Specifically, while passing a finger through the pull ring 43, bend the outer support tube assembly 3 with the other two fingers. When the outer support tube assembly 3 is bent to a certain extent, the magnetic connection blocks 313 located on one side of the upper and lower grooved tubes 311 will be adsorbed under the mutual action of their magnetic forces. The magnetic connection blocks 313 are made of alnico alloy, which has excellent magnetic properties and good mechanical strength, and can achieve a good fixed connection effect. While the airbag blocks 315 arranged in the block slots 314 correspondingly opened in the two mutually adsorbed magnetic connection blocks 313 are squeezed, the airbag blocks 315 arranged in the block slots 314 correspondingly opened in the two non-mutually adsorbed magnetic connection blocks 313 can also be pressed simultaneously with two fingers. At this time, the four airbag blocks 315 are squeezed simultaneously, and the four airbag blocks 315 simultaneously exhaust air into the gap between the inner limiting tube 33 and the outer limiting tube 32 through the corresponding air holes 316 and the inter-tube air slots 312, which can ensure the pressure received when the sliding tube 34 is pushed, thereby strengthening the extrusion of the sliding tube 34 on the corrugated hose 35, making the corrugated hose 35 fold more fully, and simultaneously closing the drainage tube 2.

[0026] Please refer to Figures 5-14 In this embodiment, the inner wall reset support assembly 53 includes an elastic hose 531. A cavity is provided inside the elastic hose 531, and 5 ml of 0.9% sodium chloride solution is injected into the cavity inside the elastic hose 531. Two groups of spring strip assemblies 532 are fixedly installed inside the elastic hose 531 in a vertically symmetric distribution. There is a gap between the two groups of spring strip assemblies 532. Each group of spring strip assemblies 532 has several, and multiple spring strip assemblies 532 are distributed in a circular array inside the elastic hose 531. A sliding assembly 533 is slidably connected to the outside of the spring strip assembly 532. The spring strip assembly 532 includes a spring strip body 5321. The projection of the spring strip body 5321 in the vertical direction is arc-shaped. A particle 5322 is fixedly connected to one side of the spring strip body 5321. The spring strip body 5321 and the particle 5322 are both made of 316 stainless steel. A chuck 5323 is fixedly connected to the inside of the spring strip body 5321. An arc angle 5324 is provided at one end of the spring strip body 5321. The sliding assembly 533 includes a grooved magnetic ring 5331. The outside of the grooved magnetic ring 5331 is in close contact with the inside of the elastic hose 531. A limiting sliding groove 5332 is opened inside the grooved magnetic ring 5331. The cross-sectional area of the limiting sliding groove 5332 is 1.2 times the cross-sectional area of the spring strip body 5321. The grooved magnetic ring 5331 is made of samarium cobalt magnet. There are two grooved magnetic rings 5331, and the two grooved magnetic rings 5331 are symmetrically distributed up and down and are magnetically repulsive to each other. The grooved magnetic ring 5331 and the magnetic sleeve ring 41 are magnetically attractive to each other.

[0027] Specifically, after the fixation between two magnetically connected blocks 313 that adsorb to each other is released, the drainage tube 2 will return from the bent state. At this time, the elastic hose 531 helps the drainage tube 2 to recover by releasing elastic potential energy. Since the spring strip body 5321 is arc-shaped, the spring strip body 5321 can better adapt to the shape of the elastic hose 531. When the spring strip body 5321 returns from the deformed state, it can provide a uniform elastic support force to the elastic hose 531. This elastic support force is transmitted to the drainage tube 2 through the elastic hose 531, further accelerating the speed at which the drainage tube 2 recovers from deformation. The sodium chloride solution in the inner cavity of the elastic hose 531 provides a certain lubricating effect to the elastic hose 531, preventing the inside of the elastic hose 531 from drying out. At the same time, the setting of the arc angle 5324 in the spring strip body 5321 can prevent the spring strip body 5321 from damaging the inner wall of the elastic hose 531. The chuck 5323 fixedly connected to the spring strip body 5321 is installed in the connecting installation groove 522, making the spring strip assembly 532 fixed to the magnetically inner through tube 521. At this time, by pulling the pull ring 43 with a finger, the pull ring 43 drives the nylon rope mesh sleeve 42 and the magnetic sleeve ring 41 to move. When the magnetic sleeve ring 41 moves, the suction force generated by the magnetic sleeve ring 41 on the grooved magnetic ring 5331 will drive the grooved magnetic ring 5331 to slide on the outside of the spring strip body 5321. When the particle 5322 passes through the limit sliding groove 5332, the friction generated between the particle 5322 and the grooved magnetic ring 5331 causes the spring strip body 5321 to vibrate and drives the elastic hose 531 to vibrate. The vibration of the elastic hose 531 helps the drainage tube 2 to recover from deformation and at the same time can also reduce the adhesion force between the inner wall of the drainage tube 2 and the accumulated fluid, preventing the accumulated fluid from staying in the tube. At the same time, the friction generated between the particle 5322 and the grooved magnetic ring 5331 causes the temperature of itself and the spring strip body 5321 to rise, and transfers the heat to the sodium chloride solution in the inner cavity of the elastic hose 531, causing the temperature of the sodium chloride solution to rise and be transmitted to the drainage tube 2 through the elastic hose 531, enhancing the flexibility of the drainage tube 2 and the fluidity of the accumulated fluid.

10. A method for using a cardiology pleural effusion drainage and extraction device according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1: Selection of the bending position of the drainage tube (2): When the drainage bottle (1) is replaced in the cardiology pleural effusion drainage and extraction device, a comprehensive evaluation of space factors is performed based on the length of the drainage tube (2) and the height of the bed, and the approximate position of the drainage tube (2) bending and clamping is determined based on the evaluation result, and the outer support tube assembly (3) is moved to change the relative position of the outer support tube assembly (3) and the drainage tube (2). When the outer support tube assembly (3) is moved, the grooved tube (311) drives the magnetic inner tube (521) to move through magnetic attraction; When the magnetic inner through tube (521) moves, the connecting sliding tube assembly (52) drives the tube head assembly (51) and the inner wall reset support assembly (53) to move, thereby changing the relative position of the inner support tube assembly (5) and the drainage tube (2), so that the outer support tube assembly (3) and the inner support tube assembly (5) are simultaneously moved to the corresponding position of the drainage tube (2) that needs to be bent and clamped; S2: The outer support tube assembly (3) is bent and fixed to complete the clamping of the drainage tube (2): one finger is passed through the pull ring (43), and the other two fingers are used to bend the outer support tube assembly (3). When the outer support tube assembly (3) is bent to a certain extent, the magnetic connection blocks (313) respectively located on one side of the upper and lower grooved tubes (311) are attracted by the interaction of the magnetic forces, and the air bag blocks (315) arranged in the corresponding inter-block grooves (314) opened in the two mutually attracted magnetic connection blocks (313) are squeezed, and the two fingers are bent at the same time. The airbag blocks (315) in the corresponding inter-block grooves (314) opened in the two magnetic connection blocks (313) that are not attracted to each other are pressed, so that the four airbag blocks (315) are squeezed at the same time, and the four airbag blocks (315) are exhausted into the gap between the inner limit tube (33) and the outer limit tube (32) through the corresponding air holes (316) and the inter-tube air grooves (312), so that the sliding tube (34) is pushed, and the sliding tube (34) squeezes the corrugated hose (35), so that the corrugated hose (35) is folded, and the drainage tube (2) is clamped and closed at the same time; S3: Unclamping and rapid recovery of the drainage tube (2): After the drainage bottle (1) of the cardiology pleural effusion drainage and extraction device is replaced, the drainage tube (2) is pulled to separate the two magnetic connection blocks (313) adsorbed together, and the corrugated hose (35) and the drainage tube (2) are deformed at the same time, so that the effusion flows again in the drainage tube (2); S4: The inner support tube assembly (5) assists the drainage tube (2) in restoring its deformation: the drainage tube (2) recovers from the bent state, the elastic hose (531) recovers from the bent state and releases elastic potential energy to provide supporting pressure on the inner wall of the drainage tube (2), and at the same time the spring bar assembly (532) returns to its original state. The pull ring (43) is pulled by fingers, so that the pull ring (43) drives the nylon rope net (42) and the magnetic ring (41) to move. When the magnetic ring (41) moves, the magnetic ring (41) is pressed against the inner wall of the drainage tube (2). The suction force generated by the grooved magnetic ring (5331) drives the grooved magnetic ring (5331) to slide on the outside of the spring bar body (5321). When the particles (5322) pass through the limiting sliding groove (5332), the friction generated between the particles (5322) and the grooved magnetic ring (5331) causes the spring bar body (5321) to vibrate and drives the elastic hose (531) to vibrate. The vibration of the elastic hose (531) generates a force on the inner wall of the drainage tube (2) so that the drainage tube (2) recovers its deformation.
