Description

Technical Field

[0001] The present invention relates to the technical field of cardiovascular care, and specifically to a postoperative care device for cardiovascular medicine. Background Art

[0002] Cardiovascular medicine is a clinical department set up in the general internal medicine departments of hospitals at all levels for the diagnosis and treatment of cardiovascular diseases. The diseases treated include angina pectoris, hypertension, arrhythmia, heart failure, premature beats, arrhythmia, myocardial infarction, cardiomyopathy, myocarditis, acute myocardial infarction and other cardiovascular diseases. After the treatment of cardiovascular diseases, there may be residual bleeding, inflammatory effusion or exudate on the postoperative wound surface or around the heart. If the effusion is not removed in time, it may lead to cardiac tamponade, tissue adhesion or cardiac function limitation, and will affect the rapid healing of the postoperative wound. Therefore, a drainage device is used to drain the effusion.

[0003] When draining the bleeding, inflammatory effusion or exudate through the drainage device, a certain degree of negative pressure is generated in the drainage bottle, and the effusion is introduced into the drainage bottle through the drainage tube by using the negative pressure. However, during the effusion drainage process, the drainage tube may be blocked due to reasons such as the accumulation of blood clots or purulent and inflammatory secretions, especially at a higher risk of blockage in the early postoperative period of hypercoagulable state of blood, which will affect the drainage of the effusion. Therefore, we propose a postoperative care device for cardiovascular medicine. Summary of the Invention

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment 1

[0034] Please refer to Figures 1 to 10 , the present invention provides a technical solution: a postoperative care device for cardiovascular medicine, including: a drainage bottle 11, a connector 12 is fixedly connected to the drainage bottle 11, and a drainage tube 13 is arranged on the connector 12.

[0035] It further includes: a drainage assembly 2, the drainage assembly 2 is arranged on the drainage bottle 11, and the drainage assembly 2 is used for forming negative pressure in the drainage bottle 11 and draining the accumulated fluid.

[0036] A blockage removal assembly 4, the blockage removal assembly 4 is arranged in the drainage bottle 11, and the blockage removal assembly 4 is used for removing blockages from the drainage tube 13.

[0037] The detection component 3 is arranged in the drainage bottle 11 and is used to detect the blockage of the drainage tube 13 and automatically control the blockage removal component 4 to remove the blockage of the drainage tube 13;

[0038] The positive pressure component 5 is arranged in the drainage bottle 11 and automatically controls the reverse ventilation into the drainage tube 13 according to the blockage removal situation of the blockage removal component 4.

[0039] One end of the drainage tube 13 is provided with a puncture needle. Through the puncture needle, it can puncture to the position of the effusion. Through the drainage component 2, a negative pressure is formed in the drainage bottle 11, and the effusion is introduced into the drainage bottle 11 through the drainage tube 13. During the drainage process of the effusion, through the detection component 3, the drainage of the effusion can be detected to judge whether the drainage tube 13 is blocked. If it is detected that the drainage tube 13 is blocked, the drainage component 2 will be automatically controlled to switch its operation and cooperate with the blockage removal component 4 to remove the blockage of the drainage tube 13 through the blockage removal component 4. After the blockage removal is completed, the drainage component 2 can be automatically controlled to immediately switch to the initial drainage state and continue to drain the effusion normally; when the blockage removal component 4 fails to remove the blockage normally, it means that the end position of the puncture needle may be blocked, so that the effusion cannot enter the puncture needle and thus the effusion cannot be drained. At this time, through the positive pressure component 5, the drainage component 2 can be automatically controlled to switch its operation and cooperate with the positive pressure component 5 to conduct reverse ventilation into the drainage tube 13. Through the introduction of gas, the end position of the puncture needle is dredged. After the dredging is completed, the drainage component 2 can be immediately controlled to switch to the initial drainage state to continue to drain the effusion normally, so as to timely handle the blockage phenomenon occurring during the drainage process and prevent it from affecting the drainage and discharge of the effusion.

[0040] The drainage component 2 includes a connecting pipe 21 fixedly communicated with the lower end of the connecting head 12. Both ends of the first four-way pipe 22 are fixedly communicated with the connecting pipe 21. Three sides of the first four-way pipe 22 away from the connecting head 12 are all installed with first solenoid valves 23. A partition 29 is fixedly arranged inside the drainage bottle 11. The inside of the drainage bottle 11 is separated into a drainage cavity 28 by the partition 29. A negative pressure pump 24 is fixedly arranged on the upper side of the drainage bottle 11. The input end of the negative pressure pump 24 is fixedly communicated with a second four-way pipe 25. Three sides of the second four-way pipe 25 away from the negative pressure pump 24 are all installed with second solenoid valves. The output end of the negative pressure pump 24 is fixedly communicated with a three-way pipe 27. Two sides of the three-way pipe 27 away from the negative pressure pump 24 are all installed with third solenoid valves. One end of the second four-way pipe 25 is fixedly communicated with an air extraction pipe 26 communicated with the drainage cavity 28. A controller is installed on one side of the drainage bottle 11. A first cover 210 is threadedly arranged on the upper side of the drainage bottle 11 where the drainage cavity 28 is located. The drainage bottle 11 can be set to be transparent. By rotating and opening the first cover 210, the inside of the drainage cavity 28 can be cleaned;

[0041] When draining the accumulated fluid, the first solenoid valve 23 on the side where the first four-way pipe 22 is connected to the connecting pipe 21 is in the open state, the second solenoid valve on the side where the second four-way pipe 25 is connected to the air extraction pipe 26 is in the open state, and the third solenoid valve on the side of the three-way pipe 27 away from the negative pressure pump 24 is in the open state. By controlling the operation of the negative pressure pump 24, the gas in the drainage cavity 28 is extracted through the air extraction pipe 26 and discharged from one end of the three-way pipe 27 away from the negative pressure pump 24, so that a negative pressure is formed in the drainage cavity 28, and thus the accumulated fluid can be drained into the drainage cavity 28 through the puncture needle, the drainage pipe 13, the connector 12, the connecting pipe 21, and the two ends where the first four-way pipe 22 is connected to the connecting pipe 21.

[0042] The detection assembly 3 includes a first detector 31 arranged on one side of the connecting pipe 21. The first detector 31 includes a rotating shaft 3101. A support 3102 fixedly arranged at the top end of the drainage bottle 11 is rotatably arranged on the outer side of the rotating shaft 3101. A plurality of receiving members 3103 are fixedly arranged at equal intervals around the circumference on one side of the rotating shaft 3101. A receiving groove is arranged on the side of the receiving member 3103 away from the rotating shaft 3101. A plurality of arc-shaped blocks 3104 are fixedly arranged at equal intervals around the circumference on the other side of the rotating shaft 3101.

[0043] When the accumulated fluid is introduced into the drainage cavity 28 through the drainage assembly 2 via the drainage pipe 13 and the connecting pipe 21, the accumulated fluid can flow down to one end of the receiving member 3103 away from the rotating shaft 3101 and accumulate in the receiving groove of the receiving member 3103. With the inflow of the accumulated fluid and the gravitational action after the accumulated fluid accumulates in the receiving groove of the receiving member 3103, the receiving member 3103 can be pressed down, causing the rotating shaft 3101 to rotate. Moreover, the arrangement of the receiving member 3103 can also play the role of the lever principle, facilitating the rotation of the rotating shaft 3101, and further enabling the plurality of arc-shaped blocks 3104 to rotate with the rotating shaft 3101.

[0044] A runner 32 is arranged on one side of the arc-shaped block 3104. A connecting rod member 33 that movably penetrates the side wall of the drainage bottle 11 is rotatably arranged on one side of the runner 32. A moving block 34 is fixedly arranged at the outer end of the connecting rod member 33. A connecting shell 35 fixedly arranged on the side wall of the drainage bottle 11 is slidably arranged on the outer side of the moving block 34. The connecting rod member 33 movably penetrates one side of the connecting shell 35. A corrugated pipe 316 fixedly arranged on the inner wall of the drainage bottle 11 is fixedly sleeved on the outer side of the connecting rod member 33. When the connecting rod member 33 moves, the corrugated pipe 316 extends or contracts. The arrangement of the corrugated pipe 316 can prevent the gas in the drainage cavity 28 from flowing through the movable penetration part of the connecting rod member 33 and the side wall of the drainage bottle 11, so as to ensure the formation of negative pressure in the drainage cavity 28. A limiting rod 36 fixedly arranged on the inner side of the connecting shell 35 is symmetrically penetrated and slidably arranged on the moving block 34. The two ends of the limiting rod 36 are respectively fixed to the two inner sides of the connecting shell 35. The two limiting rods 36 can play a guiding role in the movement of the moving block 34.

[0045] The connecting shell 35 is fixedly provided with a mounting block 37 on one side of the moving block 34. A first switch 38 is mounted on one side of the mounting block 37. The side of the moving block 34 close to the first switch 38 is set as an inclined surface to facilitate the pressing of the first switch 38. One end of the moving block 34 is fixedly provided with a connecting rod 39. One end of the connecting rod 39 is fixedly provided with a limiting bladder 310. A limiting shell 311 fixedly connected to the connecting shell 35 is sleeved outside the limiting bladder 310. An air bladder 312 is arranged on one side of the moving block 34. A stop block 314 fixedly connected to the connecting shell 35 is fixedly provided on one side of the air bladder 312. A ventilation pipe 313 is fixedly connected between the air bladder 312 and the limiting bladder 310. The ventilation pipe 313 is set as a flexible pipe. A first spring 315 fixedly connected to the inner side of the connecting shell 35 is fixedly provided on one side of the moving block 34;

[0046] When multiple arc-shaped blocks 3104 rotate with the rotating shaft 3101, through the pressing action of the arc-shaped blocks 3104 on the runner 32, the link member 33 can be made to move away from the arc-shaped blocks 3104, so that the moving block 34 moves along the limiting rod 36 close to the limiting shell 311. The first spring 315 elongates and the corrugated pipe 316 contracts, so that the moving block 34 presses the first switch 38. At the same time, with the movement of the moving block 34, the connecting rod 39 and the limiting bladder 310 can be driven to move synchronously, so that the limiting bladder 310 moves to the outside of the limiting shell 311, and the moving block 34 can be made to squeeze the air bladder 312, so that the gas in the air bladder 312 enters the limiting bladder 310 through the ventilation pipe 313, making the limiting bladder 310 expand. Through the limiting action of the limiting shell 311 on the expanded limiting bladder 310, the moving block 34 can be prevented from immediately moving reversely and resetting under the elastic force of the first spring 315. With the continuous inflow of the accumulated liquid and the rotation of multiple arc-shaped blocks 3104 with the rotating shaft 3101, during the process of draining the accumulated liquid, the moving block 34 can be kept in a state of pressing the first switch 38.

[0047] The plugging and draining assembly 4 includes a communicating pipe 42 fixedly connected to one end of the second four-way pipe 25. The inside of the drainage bottle 11 is separated into a plugging and draining cavity 41 by a partition plate 29. The communicating pipe 42 is communicated with the plugging and draining cavity 41. One end of the first four-way pipe 22 is fixedly connected with a plugging and draining pipe 43 communicated with the plugging and draining cavity 41. A second detecting member 44 is arranged on one side of the plugging and draining pipe 43. The structure of the second detecting member 44 is the same as that of the first detecting member 31. The supporting member 3102 of the second detecting member 44 is fixedly connected to the inner top end of the drainage bottle 11. A connecting block 45 fixedly connected to the partition plate 29 is arranged on one side of the arc-shaped block 3104 of the second detecting member 44. A second switch 46 is mounted on one side of the connecting block 45. A second sealing cover 47 is threadedly arranged on the upper side of the drainage bottle 11 where the plugging and draining cavity 41 is located. By rotating and opening the second sealing cover 47, it is convenient to clean the inside of the plugging and draining cavity 41. Drainage pipes are arranged on the lower sides of the drainage cavity 28 and the plugging and draining cavity 41 of the drainage bottle 11. Control valves are installed on the drainage pipes. By opening the control valves, the accumulated liquid in the drainage cavity 28 and the plugging and draining cavity 41 can be discharged;

[0048] If the drainage tube 13 becomes blocked, the accumulated fluid will no longer flow into the drainage cavity 28 normally. This will cause the rotating shaft 3101 of the first detection member 31 and the multiple arc-shaped blocks 3104 to stop rotating. Under the elastic force of the first spring 315, the gas in the expanded limiting bladder 310 will gradually flow back into the airbag 312, causing the limiting housing 311 to gradually release the restrictive effect on the limiting bladder 310. Finally, under the elastic force of the first spring 315, the moving block 34 will move in the reverse direction and reset, so that the moving block 34 no longer presses against the first switch 38. Then, the first electromagnetic valve 23 on the side where the first four-way pipe 22 is connected to the blockage removal pipe 43 will be opened, and the first electromagnetic valve 23 on the side where the first four-way pipe 22 is connected to the connecting pipe 21 will be closed. The second electromagnetic valve on the side where the second four-way pipe 25 is connected to the communication pipe 42 will be opened, and the second electromagnetic valve on the side where the second four-way pipe 25 is connected to the air extraction pipe 26 will be closed. Thus, the extraction of gas from the drainage cavity 28 can be stopped, the gas in the blockage removal cavity 41 can be extracted through the communication pipe 42, and discharged from one end of the three-way pipe 27 away from the negative pressure pump 24, creating a relatively large negative pressure in the blockage removal cavity 41 to increase the suction force and introduce the blocked part into the blockage removal cavity 41 through the blockage removal pipe 43. Similarly, when the blocked part of the accumulated fluid is introduced into the blockage removal cavity 41 through the blockage removal pipe 43, the receiving member 3103 of the second detection member 44 can be rotated, causing the rotating shaft 3101 of the second detection member 44 and the multiple arc-shaped blocks 3104 to rotate, so that the arc-shaped blocks 3104 press against the second switch 46. Then, the first electromagnetic valve 23 on the side where the first four-way pipe 22 is connected to the blockage removal pipe 43 will be closed, the first electromagnetic valve 23 on the side where the first four-way pipe 22 is connected to the connecting pipe 21 will be opened, the second electromagnetic valve on the side where the second four-way pipe 25 is connected to the communication pipe 42 will be closed, and the second electromagnetic valve on the side where the second four-way pipe 25 is connected to the air extraction pipe 26 will be opened. Then, the accumulated fluid will continue to be introduced into the drainage cavity 28 to continue the normal drainage of the accumulated fluid. In this way, it can also prevent the relatively large negative pressure in the blockage removal cavity 41 after blockage removal from causing the drainage of the accumulated fluid to be too fast and causing discomfort to the patient.

By rotating and opening the third sealing cover, it is convenient to clean the inside of the positive pressure chamber 51. A drain pipe is arranged on the lower side of the positive pressure chamber 51 of the drainage bottle 11, and a control valve is installed on the drain pipe.

[0051] During the blockage removal process by the blockage removal assembly 4, as the gas in the blockage removal chamber 41 is pumped out, under the action of the external atmospheric pressure, the pressing block 55 can move downward, and the second spring 59 extends. When the pressing block 55 moves downward to press against the third switch 58, that is, when the negative pressure formed in the blockage removal chamber 41 reaches a certain pressure, if the arc-shaped block 3104 of the second detection member 44 still does not press against the second switch 46 at this time, it means that the blockage removal assembly 4 fails to remove the blockage normally. It may be that the end position of the puncture needle is blocked, resulting in the accumulated fluid being unable to enter the puncture needle, and thus the normal drainage of the accumulated fluid cannot be carried out. Then, the first solenoid valve 23 on the side where the first four-way pipe 22 is connected to the air guide pipe 53 will be controlled to open, and the first solenoid valves 23 on the other two sides of the first four-way pipe 22 will be closed. The second solenoid valve on the side of the second four-way pipe 25 away from the air extraction pipe 26 and the communication pipe 42 will be opened, and the second solenoid valves on the sides where the second four-way pipe 25 is connected to the air extraction pipe 26 and the communication pipe 42 will be closed. The third solenoid valve on the side where the tee pipe 27 is connected to the air delivery pipe 52 will be opened, and the third solenoid valve on the side of the tee pipe 27 away from the negative pressure pump 24 will be closed. Thus, through the negative pressure pump 24, the external gas can be passed through one port of the second four-way pipe 25 away from the air extraction pipe 26 and the communication pipe 42, and conveyed into the positive pressure chamber 51 through the air delivery pipe 52. And a filter (not shown in the figure) is installed on one port of the second four-way pipe 25 away from the air extraction pipe 26 and the communication pipe 42 to purify and filter the external gas.

[0052] One end of the first four-way pipe 22 is fixedly connected to an air guide pipe 53 communicating with the positive pressure chamber 51. Inside the positive pressure chamber 51, there is a fixed block 511. On the upper side of the fixed block 511, there is a second corrugated plate 513 fixedly arranged on the inner side of the drainage bottle 11. The through hole 510 on the upper side of the fixed block 511 is located inside the second corrugated plate 513, enabling the upper side of the fixed block 511 to communicate with the outside. When the fixed block 511 moves up and down, the second corrugated plate 513 extends or contracts. The setting of the second corrugated plate 513 can separate the upper side and the lower side of the fixed block 511. On both sides of the fixed block 511, there are second guide rods 512 symmetrically and slidably arranged on the inner side of the drainage bottle 11. The second guide rods 512 can guide the movement of the fixed block 511. On the upper side of the fixed block 511, there is a third spring 514 fixedly arranged on the inner side of the drainage bottle 11;

[0053] As the gas is delivered into the positive pressure chamber 51, the air pressure inside the positive pressure chamber 51 will increase, causing the fixed block 511 to move upward, compressing the third spring 514 and contracting the second corrugated plate 513. At the same time, the gas delivered into the positive pressure chamber 51 can be reversely introduced into the drainage pipe 13 through the air guide pipe 53, and then into the puncture needle, flushing the blocked part at the end of the puncture needle and dredging the end position of the puncture needle to ensure the continuous drainage of the effusion.

[0054] On one side of the fixed block 511, there is an installation shell 515. Inside the installation shell 515, there is an electromagnet block 516. Inside the installation shell 515, there is an inclined tooth block 517 slidably arranged and adsorbed to the electromagnet block 516. On one side of the inclined tooth block 517, there are fourth springs 518 symmetrically fixedly arranged on the inner side of the installation shell 515. On one side of the inclined tooth block 517, there is a tooth rod member 519, which cooperates with the inclined tooth block 517. On one side of the tooth rod member 519, there is a limiting plate 520 slidably arranged. The upper end of the limiting plate 520 is fixed to the inner top end of the drainage bottle 11. The limiting plate 520 can limit the up and down movement of the tooth rod member 519. On one side of the limiting plate 520, there is a fifth spring 521 fixedly arranged with the tooth rod member 519. On the lower side of the tooth rod member 519, there is a support block 522 fixedly arranged on the inner wall of the drainage bottle 11. On the upper side of the support block 522, there is a fourth switch 523;

[0055] With the delivery of gas into the positive pressure chamber 51, the upward movement of the fixed block 511 can drive the upward movement of the mounting shell 515, causing the helical gear block 517 to move upward along one side of the toothed rod member 519. After the dredging of the end position of the puncture needle is completed, the air pressure in the positive pressure chamber 51 will instantaneously decrease. Under the action of the external atmospheric pressure and the third spring 514, the fixed block 511 can be moved downward, causing the helical gear block 517 to drive the toothed rod member 519 to move downward. The fifth spring 521 elongates, causing the toothed rod member 519 to press against the fourth switch 523, which will control the drainage assembly 2 to switch to the initial state, that is, the first solenoid valve 23 on the side where the first four-way pipe 22 is connected to the connecting pipe 21 is opened, and the first solenoid valves 23 on the other two sides of the first four-way pipe 22 are closed. The second solenoid valve on the side where the second four-way pipe 25 is connected to the air extraction pipe 26 is opened, and the second solenoid valves on the other two sides of the second four-way pipe 25 are closed. The third solenoid valve on the side of the three-way pipe 27 away from the negative pressure pump 24 is opened, and the third solenoid valve on the side where the three-way pipe 27 is connected to the air delivery pipe 52 is closed. Then, the accumulated fluid is continuously introduced into the drainage chamber 28, and the normal drainage of the accumulated fluid is continued. In this way, it is also possible to prevent the gas in the positive pressure chamber 51 from continuing to flow into the drainage pipe 13 after dredging. At the same time, the pressing action on the fourth switch 523 can cause the electromagnet block 516 to be energized to generate an adsorption effect on the helical gear block 517, causing the helical gear block 517 to move close to the electromagnet block 516 and disengage from the toothed rod member 519. The fourth spring 518 elongates, and under the elastic force of the fifth spring 521, the toothed rod member 519 moves upward to reset.
