Description

Technical Field

[0001] The invention belongs to the technical field of cardiovascular medicine, in particular to a cardiovascular effusion drainage device. Background Art

[0002] Cardiovascular medicine is a clinical department set up by the internal medicine department of hospitals at all levels for the diagnosis and treatment of cardiovascular diseases. The diseases treated include angina pectoris, hypertension, constrictive pericarditis, heart failure, premature beats, arrhythmia, myocardial infarction, cardiomyopathy, myocarditis, acute myocardial infarction and other cardiovascular diseases. Most patients with cardiovascular diseases have fluid substances such as gas, exudate, blood, pus and other components in their bodies. These are generally called drainage materials. The drainage materials themselves are foreign bodies. The longer they stay in the body, the more likely they are to be infected around the drainage materials. Therefore, when drainage materials are found in the patient's body, they need to be drained out of the body as soon as possible.

[0003] A patent with publication number CN112915274B discloses a cardiovascular drainage device. Through the coordinated use of a driving gear and a transmission gear, and the mutual cooperation between the decomposition disks, the blocky substances in the patient's blood stasis or fluid accumulation can be decomposed, and the drainage device can be prevented from being blocked, which facilitates the drainage operation of the blood stasis or fluid accumulation. The coordinated use of gear 1 and the push disk, and the coordinated use of the reflux fluid and the reflux tube can prevent the backflow of blood stasis or fluid accumulation, and at the same time, the blood stasis or fluid accumulation can be continuously transported, and the drainage effect of the blood stasis or fluid accumulation is good.

[0004] In the above-mentioned prior art, when the drainage tube is inserted into the patient's body to discharge the drainage, in severe cases, the drainage time may be longer and the discharged drainage may be more, and it is necessary to observe the drainage in the container at all times. In the prior art, a drainage tube is only equipped with one collecting bag, and it is necessary to observe the collection of the drainage in the rear lace at all times. When a lot of drainage is collected in the collecting bag, the collecting bag needs to be replaced in time.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] Embodiment 1

[0034] like Figure 1-5 As shown, a cardiovascular effusion drainage device described in an embodiment of the present invention includes a first hose 1, a collecting bag 21 is installed at one end of the first hose 1 through a second hose 2, a spare bag 23 is installed at one side of the second hose 2 through a third hose 22, a first extrusion device is provided on the outside of the second hose 2, the first extrusion device includes a first circular frame 26 located on the outside of the second hose 2, the first circular frame 26 is located on one side of the collecting bag 21, and first extrusion plates 264 are slidably provided at the upper and lower ends of the inner side of the first circular frame 26, a second extrusion device is provided on the outside of the third hose 22, the second extrusion device includes a second circular frame 27 located on one side of the spare bag 23, and second extrusion plates 272 are slidably provided at the upper and lower ends of the inner side of the second circular frame 27.

[0035] Specifically, most cardiovascular disease patients have fluid substances such as gas, exudate, blood, pus and other components in their bodies, which are generally called drainage materials. When drainage materials are found in the patient's body, they need to be drained out of the body as soon as possible. When dealing with effusion drainage, it is usually necessary to first insert a pericardial catheter through ultrasound intervention. In this process, after the puncture needle enters the pericardial cavity, a guide wire is inserted, and then the drainage tube is inserted along the guide wire. Then, the end of the drainage tube away from the pericardial cavity is connected to a negative pressure source to drain the effusion in the pericardium. After the drainage tube is inserted, the drainage tube is fixed to the patient's skin, and then the drainage material flows into the container along the drainage tube for collection. In severe cases, the drainage time may be long for the patient, and it is necessary to always observe the drainage material in the container and replace the container in time to prevent the drainage material from overflowing. When using the present invention, the first hose 1 is connected to the drainage tube, and then the drainage tube is inserted into the patient's pericardial cavity, and then the drainage tube is drained. The drainage flows into the second hose 2 along the first hose 1, and then enters the collecting bag 21. When the drainage flow in the collecting bag 21 is full, the collecting bag 21 gradually expands and increases in volume. At this time, the two first squeezing plates 264 are driven to approach each other to squeeze the second hose 2 in the middle, so that the drainage cannot enter the collecting bag 21, and the drainage in the collecting bag 21 is prevented from overflowing. At the same time, the two second squeezing plates 272 are driven away from each other to keep the third hose 22 unobstructed, so that the drainage can flow into the spare bag 23 along the third hose 22, so as to buy more time for replacing the collecting bag 21. When replacing the collecting bag 21, the second hose 2 is clamped by the first squeezing plate 264, and then the collecting bag 21 is removed to prevent the drainage from overflowing. At the same time, the drainage can continuously enter the spare bag 23 through the third hose 22 to prevent the drainage from staying in the second hose 2 and causing blockage, which can effectively prevent the drainage from overflowing and effectively reduce the occurrence of drainage accumulation and blockage.

[0036] like Figure 2-Figure 4 As shown, the second hose 2 is installed with the collecting bag 21 through the circular ring 24, and the first rectangular blocks 241 are fixedly connected on both sides of the circular ring 24, and one side of the first rectangular block 241 is fixedly connected to the first circular frame 26 through the second L-shaped block 245, and the upper and lower ends of the first rectangular block 241 are fixedly connected with the third rectangular strip 242, and the third rectangular strip 242 is rotatably connected with the connecting rod 243 through the torsion spring, and the connecting rod 243 is located on both sides of the collecting bag 21, and the circular ring 24 is provided with a U-shaped plate 25 on the side away from the collecting bag 21, and the U-shaped plate 25 can slide on the outside of the second hose 2, and the second L-shaped pointed block 262 is fixedly connected on the opposite side of the first squeezing plate 264, and the second L-shaped pointed block 262 passes through the upper and lower ends of the first circular frame 26 and can slide, and the first bevel block 251 is fixedly connected to the position corresponding to the second L-shaped pointed block 262 on the side of the U-shaped plate 25 close to the first circular frame 26, and the bevel side of the first bevel block 251 can slide on the bevel side of the second L-shaped pointed block 262.

[0037] Specifically, when a large amount of drainage is collected in the collecting bag 21, the collecting bag 21 is made of a plastic bag. At this time, the volume of the collecting bag 21 gradually expands, pushing the connecting rods 243 on both sides outward, and the connecting rods 243 on both sides rotate at the same time, driving the U-shaped plate 25 to move away from the collecting bag 21. The U-shaped plate 25 drives the first bevel block 251 to slide along the bevel of the second L-shaped pointed block 262, so that the second L-shaped pointed block 262 drives the first extrusion plate 264 to approach the second hose 2 at the same time. The first extrusion plate 264 is made of a magnet with a small magnetic force. After the two first extrusion plates 264 approach each other to a certain distance, they adsorb each other and clamp the second hose 2, so that the drainage cannot enter the collecting bag 21, and then it can enter the spare bag 23 to prevent the drainage from overflowing.

[0038] like Figure 3 As shown, one end of the connecting rod 243 away from the third rectangular bar 242 is rotatably connected to a cylindrical wheel 244 , and the cylindrical wheel 244 can roll along the outer side of the collecting bag 21 .

[0039] Specifically, when more and more drainage material is collected in the collection bag 21, the collection bag 21 gradually expands, driving the connecting rods 243 on both sides to rotate along the side walls of the collection bag 21. The connecting rods 243 roll along the outside of the collection bag 21 through the cylindrical wheel 244, reducing the friction between the connecting rods 243 and the outside of the collection bag 21, thereby preventing the collection bag 21 from being scratched.

[0040] like Figure 4 As shown, L-shaped grooves 261 are respectively provided at both ends of the first circular frame 26 close to the U-shaped plate 25, and rectangular frames 252 are respectively fixedly connected to the positions of the U-shaped plate 25 corresponding to the L-shaped grooves 261, and the lower ends of the rectangular frames 252 are respectively slidably connected to the first L-shaped pointed blocks 253, and the first L-shaped pointed blocks 253 can slide in the L-shaped grooves 261, and the upper ends of the first L-shaped pointed blocks 253 are fixedly connected to the cylindrical bar 254, and the cylindrical bar 254 passes through the upper end of the rectangular frame 252, and a first spring 255 is provided on the outside of the cylindrical bar 254.

[0041] Specifically, when the drainage in the collection bag 21 increases, the U-shaped plate 25 squeezes the second L-shaped pointed block 262 through the first bevel block 251, driving the two first squeezing plates 264 to approach each other to clamp the second hose 2. When the two first squeezing plates 264 approach each other, the first L-shaped pointed block 253 gradually slides into the L-shaped groove 261. When the bevel of the first L-shaped pointed block 253 slides along the side of the L-shaped groove 261, the first L-shaped pointed block 253 slides downward and stretches the first spring 255. When the two first squeezing plates 264 are close to each other, the first L-shaped pointed block 253 slides to the L-shaped groove 261. shaped groove 261, at this time, the first spring 255 releases its elastic force and pulls the first L-shaped pointed block 253 upwards. When it is clamped in the L-shaped groove 261, the two first squeezing plates 264 are further prevented from separating and the drainage flow is prevented from flowing out. After the collecting bag 21 is replaced, the cylindrical bar 254 is pushed to drive the first L-shaped pointed block 253 to slide downward and stretch the first spring 255, and then the U-shaped plate 25 is driven to move toward the side close to the collecting bag 21 until the first L-shaped pointed block 253 completely slides out of the L-shaped groove 261, so that the two first squeezing plates 264 are away from each other, so that the drainage can flow into the collecting bag 21.

[0042] like Figure 4 As shown, alarms 263 are respectively provided on both sides of the upper end of the first circular frame 26 .

[0043] Specifically, when the collection bag 21 is filled with drainage material, the first L-shaped pointed block 253 slides completely into the L-shaped groove 261. A switch is installed inside the L-shaped groove 261. The first L-shaped pointed block 253 touches the switch to cause the alarm 263 to sound an alarm to remind the collection bag 21 to be replaced.

[0044] like Figure 5 As shown, a second L-shaped block 245 on one side is fixedly connected to the second circular frame 27 through a second rectangular block 246, and a third L-shaped pointed block 271 is fixedly connected to the opposite side of the second extrusion plate 272. The third L-shaped pointed block 271 passes through the upper and lower ends of the second circular frame 27 and can slide. The third L-shaped pointed block 271 is fixedly connected to the second circular frame 27 through a second spring 273, and a second bevel block 256 is fixedly connected to a position on one side of the U-shaped plate 25 relative to the third L-shaped pointed block 271. The bevel side of the second bevel block 256 can slide on the bevel side of the third L-shaped pointed block 271.

[0045] Specifically, when the collection bag 21 is filled with drainage material, the two first squeezing plates 264 are driven to approach each other, and the U-shaped plate 25 drives the second bevel block 256 to approach the third L-shaped pointed block 271. The second squeezing plate 272 is initially in a close contact state, clamping the third hose 22 in the middle to prevent the drainage material from entering the third hose 22. When the second bevel block 256 approaches the third L-shaped pointed block 271, the second bevel block 256 slides back along the bevel of the third L-shaped pointed block 271, so that the third L-shaped pointed block 271 drives the second squeezing plate 272 to slide away from the third hose 22, and at the same time stretches the second spring 273. At this time, the drainage material can flow into the spare bag 23 along the third hose 22.

[0046] like Figure 6-Figure 9 As shown, a backflow prevention component is provided between the first hose 1 and the second hose 2, and the backflow prevention component includes a first rectangular box 11 fixedly connected to one end of the first hose 1, a first rectangular plate 12 is fixedly connected to the middle part of the inner side of the first rectangular box 11 away from the first hose 1, a second rectangular plate 121 is slidably provided on one side of the first rectangular plate 12, a third rectangular plate 123 is fixedly connected to one side of the upper end of the first rectangular plate 12, a second rectangular box 15 is fixedly connected to one side of the first rectangular box 11, a second cylinder 17 is fixedly connected to one side of the lower end of the first hose 1, the second cylinder 17 is communicated with the inside of the first rectangular box 11, a one-way valve 176 is provided at the connection between the second cylinder 17 and the second cylinder 17, a circular plate 171 is slidably provided in the second cylinder 17, and a second connecting pipe 174 is fixedly connected to one side of the second cylinder 17.

[0047] Specifically, when part of the drainage material enters the first rectangular box 11 from the first hose 1, the second rectangular plate 121 is driven to slide out from the first rectangular plate 12, so that the second rectangular plate 121 slides to one side of the first rectangular box 11, and the upper and lower parts of the first rectangular box 11 are separated. The first hose 1 is located at the upper end of the first rectangular box 11, and the second hose 2 is located at the lower end of the first rectangular box 11. Then, the circular plate 171 is driven to slide in the second cylinder 17 toward the side close to the first rectangular box 11. The second cylinder 17 is filled with saline solution, and the circular plate 171 pushes the saline solution into the second cylinder 17. The lower end of the interior of a rectangular box 11 is mixed with the drainage, which is rich in protein and white blood cells and may have a higher viscosity. Mixing with physiological saline can dilute the drainage. Since the upper and lower parts of the first rectangular box 11 are isolated by the first rectangular plate 12 and the second rectangular plate 121, the first hose 1 can continuously discharge the drainage into the upper half of the first rectangular box 11, and the circular plate 171 pushes the physiological saline into the lower half of the first rectangular box 11 to mix with the drainage, and at the same time allows the drainage to flow into the second hose 2. The drainage mixed with the physiological saline can reduce blockage and then enters the collection bag 21 for collection.

[0048] like Figure 7-Figure 9As shown, the upper end of the first rectangular plate 12 is provided with a first rectangular hole 122, the upper end of the second rectangular plate 121 can slide in the first rectangular hole 122 through the first L-shaped block 1221, the first rectangular box 11 is provided with a second rectangular hole 16 on the side close to the second rectangular box 15, the first L-shaped block 1221 can slide in the second rectangular hole 16, one side of the first rectangular box 11 is fixedly connected with a second rectangular bar 18, the second rectangular bar 18 is located inside the second rectangular box 15, and the second rectangular bar 18 is slidably connected with a first toothed plate 18 at the middle of one end close to the first rectangular box 11 The first rectangular bar 173 is fixedly connected to the first L-shaped block 1221 at one end, a rectangular groove 181 is provided on one side of the second rectangular bar 18, a third rectangular hole 175 is provided on the upper side of one end of the second cylinder 17 away from the first rectangular box 11, and a first rectangular bar 173 is fixedly connected to the side of the circular plate 171 away from the first rectangular box 11 through a second cylindrical rod 172, and the first rectangular bar 173 can slide in the third rectangular hole 175, and a second rack 183 is fixedly connected to the upper end of the first rectangular bar 173, and the second rack 183 can slide in the rectangular groove 181.

[0049] Specifically, after part of the drainage flows into the first rectangular box 11, the first rack 182 is driven to slide at one end of the second rectangular bar 18, and the first rack 182 drives the second rectangular plate 121 to slide outward from the inside of the first rectangular plate 12 through the first L-shaped block 1221 until it slides to one side of the inside of the first rectangular box 11, and then drives the second rack 183 to move in the rectangular groove 181 toward the side close to the first rectangular box 11, and the second rack 183 drives the circular plate 171 to move toward the side close to the first rectangular box 11 through the first rectangular bar 173, and the circular plate 171 pushes the saline solution contained in the second cylinder 17 into the first rectangular box 11 to mix with the drainage, and uses the thrust to push the drainage mixed with the saline solution into the second hose 2, and when the saline solution is pushed in, the second rectangular plate 121 completely slides out from the inside of the first rectangular plate 12 and fits tightly against the first rectangular box 11 inner wall, so that the drainage at the lower end of the second rectangular plate 121 can only flow into the second hose 2. Since a one-way valve 176 is provided at the connection between the second cylinder 17 and the first rectangular box 11, the drainage inside the first rectangular box 11 cannot flow into the second cylinder 17, and the circular plate 171 is driven to slide to the side away from the first rectangular box 11. The second connecting pipe 174 is connected to an external container, and the container is filled with saline. The saline is sucked into the second cylinder 17, and then the second rectangular plate 121 is driven to slide into the first rectangular plate 12, so that the drainage flows to the lower end of the first rectangular plate 12, and then the above operation is performed again to continuously dilute the drainage. The upper and lower ends of the first rectangular box 11 are isolated by driving the second rectangular plate 121 to slide in the first rectangular plate 12, and then dilution is performed to prevent the drainage from flowing back and reduce the problem of drainage blockage.

[0050] like Figure 7 As shown, a sealing strip 1211 is provided on the edge of the second rectangular plate 121 .

[0051] Specifically, the sealing strip 1211 provided on the edge of the second rectangular plate 121 can keep the second rectangular plate 121 sealed when sliding. When the second rectangular plate 121 slides from the first rectangular plate 12 to one side of the first rectangular box 11, the upper and lower parts of the first rectangular box 11 are completely isolated.

[0052] Embodiment 2

[0053] like Fig.10 As shown, compared with Example 1, another embodiment of the present invention is: a first cylinder 14 is fixedly connected to one side of the lower end of the first rectangular box 11 through a first connecting tube 13, a first cylindrical rod 141 is rotatably connected to the middle of the first cylinder 14, and paddles 142 are respectively fixed to both sides of the first cylindrical rod 141.

[0054] Specifically, when the drainage mixed with saline flows into the first cylinder 14 through the first connecting tube 13, the first cylindrical rod 141 is driven to rotate, and the first cylindrical rod 141 drives the paddle 142 to rotate to stir the saline and the drainage to ensure a more uniform mixing and reduce the risk of blockage.

[0055] Working principle: when draining a patient, the first hose 1 is connected to the drainage tube, and then the drainage tube is placed in the patient's pericardial cavity. When part of the drainage material enters the first rectangular box 11 from the first hose 1, the first rack 182 is driven to slide at one end of the second rectangular bar 18. The first rack 182 drives the second rectangular plate 121 to slide outward from the inside of the first rectangular plate 12 through the first L-shaped block 1221 until it slides to one side of the inside of the first rectangular box 11, and then drives the second rack 183 in the rectangular groove. 181 moves toward the side of the first rectangular box 11, and the second rack 183 drives the circular plate 171 to move toward the side of the first rectangular box 11 through the first rectangular bar 173. The circular plate 171 pushes the saline solution contained in the second cylinder 17 into the first rectangular box 11 to mix with the drainage material. When the saline solution is pushed in, the second rectangular plate 121 completely slides out from the inside of the first rectangular plate 12 and clings to the inner wall of the first rectangular box 11, so that the drainage material at the lower end of the second rectangular plate 121 can only be discharged from the first connecting pipe 11. After 13 flows into the first cylinder 14, the first cylindrical rod 141 is driven to rotate, and the first cylindrical rod 141 drives the paddle 142 to rotate, so as to stir the physiological saline and the drainage material to ensure a more uniform mixing, and then flows into the second hose 2. Since a one-way valve 176 is provided at the connection between the second cylinder 17 and the first rectangular box 11, the drainage material inside the first rectangular box 11 cannot flow into the second cylinder 17, and the circular plate 171 is driven to slide to the side away from the first rectangular box 11, and the second connecting pipe 174 is connected to the external container, and the container is filled with physiological saline, and the physiological saline is sucked into the second cylinder 17, and then the second rectangular plate 121 is driven to slide into the first rectangular plate 12, so that the drainage flows to the lower end of the first rectangular plate 12, and then the above operation is performed again to continuously dilute the drainage material, and the upper and lower ends of the first rectangular box 11 are isolated by driving the second rectangular plate 121 to slide in the first rectangular plate 12, and then dilution is performed to prevent the drainage material from flowing back and reduce the problem of drainage material blockage;

[0056] The drainage material flows into the collecting bag 21 along the second hose 2. The collecting bag 21 is made of a plastic bag. At this time, the volume of the collecting bag 21 gradually expands, pushing the connecting rods 243 on both sides outward. The connecting rods 243 on both sides rotate at the same time and drive the U-shaped plate 25 to move away from the collecting bag 21. The U-shaped plate 25 drives the first bevel block 251 to slide along the bevel of the second L-shaped pointed block 262, so that the second L-shaped pointed block 262 drives the first extrusion plate 264 to approach the second hose 2 at the same time. The material of the first extrusion plate 264 is a magnet with a small magnetic force. After the two first extrusion plates 264 approach each other to a certain distance, they are adsorbed on each other to collect the first extrusion plate 264. The two hoses 2 are clamped, and at the same time, the first L-shaped pointed block 253 gradually slides into the L-shaped groove 261. When the hypotenuse of the first L-shaped pointed block 253 extends to one side of the L-shaped groove 261, the first L-shaped pointed block 253 slides downward and stretches the first spring 255. When the two first extrusion plates 264 are pressed against each other, the first L-shaped pointed block 253 slides into the L-shaped groove 261. At this time, the first spring 255 releases its elastic force and pulls the first L-shaped pointed block 253 upward. When it is clamped into the L-shaped groove 261, the two first extrusion plates 264 are further prevented from separating, and the drainage is prevented from flowing out, so that the drainage cannot enter the collection bag 21.

[0057] When the collecting bag 21 is filled with drainage, the two first squeezing plates 264 are driven to approach each other, and the U-shaped plate 25 drives the second bevel block 256 to approach the third L-shaped pointed block 271. The second squeezing plate 272 is initially in a close contact state, clamping the third hose 22 in the middle to prevent the drainage from entering the third hose 22. When the second bevel block 256 approaches the third L-shaped pointed block 271, the second bevel block 256 slides back along the bevel of the third L-shaped pointed block 271, so that the third L-shaped pointed block 271 drives the second squeezing plate 272 to slide away from the third hose 22, and at the same time stretches the second spring 273. At this time, the drainage can flow into the spare bag 23 along the third hose 22.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
