Description

Technical Field

[0001] The invention relates to the technical field of pericardiocentesis, in particular to a pericardiocentesis and fluid extraction device for cardiology. Background Art

[0002] Cardiology is a discipline in clinical medicine that specializes in the study and treatment of cardiovascular system diseases, covering structural abnormalities, functional disorders, and related metabolic diseases of the heart and blood vessels. Its diagnosis and treatment scope includes hemodynamic abnormalities, coronary artery disease, myocardial dysfunction, cardiac rhythm disorders, valvular dysfunction, and congenital structural defects. Common symptoms include chest pain, dyspnea, palpitations, fatigue, etc., which can cause cardiogenic shock or sudden death in severe cases. Pericardiocentesis is a diagnostic and treatment technique that uses a puncture needle to extract pericardial effusion or inject medication to diagnose the nature of the effusion and relieve symptoms of cardiac tamponade. Indications include large pericardial effusions, purulent pericarditis, etc., and contraindications include coagulation disorders, aortic dissection, etc.

[0003] Existing methods of extracting fluid with a puncture needle mostly involve extracting fluid through a needle tube. However, in actual use, when using a needle tube to extract fluid, it is necessary to always ensure that the puncture needle is in the correct position, and the needle tube needs to be pulled at the same time, which is more troublesome to use. In addition, if there is too much fluid accumulation, the needle tube needs to be replaced, which is even more troublesome. In addition, during the existing pericardial extraction process, if the pericardial effusion contains a lot of fibrin or flocs, blockage may occur. It may be necessary to repeatedly adjust the puncture site or replace the device, which is not conducive to the rapid extraction of fluid. Summary of the Invention

[0039] The mounting mechanism 9 includes a first magnetic block 901 and a second magnetic block 909. The first magnetic block 901 is fixedly mounted on the L-shaped tube 26, and the second magnetic block 909 is fixedly mounted on one end of the hose 10;

[0040] The dredging mechanism 11 includes a mounting tube 1102, a rotating shaft 1105, and dredging blades 1106. The rotating shaft 1105 is movably mounted in the mounting tube 1102, and the dredging blades 1106 are fixedly mounted on the rotating shaft 1105.

[0041] The closing mechanism 12 includes an arc block 1201 and a V-shaped pressure block 1203, and the arc block 1201 is movably provided with a V-shaped pressure block 1203. The present device replaces the traditional manual liquid extraction method with an air pump 3, which is more stable to operate and can store more accumulated liquid. The extraction part of the device is reusable, while the liquid collection box 5 and the hose 10 are disposable components, which reduces the cost of use while ensuring safety. The device is provided with an air extraction mechanism 8 to ensure stability. Even if the air pump 3 fails, the liquid can still be extracted through the air extraction mechanism 8. The installation mechanism 9 makes the connection between the liquid collection box 5 and the hose 10 more convenient, reducing the assembly time of the device. In addition, the dredging mechanism 11 can dredge the accumulated liquid in the hose 10, thereby enhancing the stability of the device.

[0042] Furthermore, a second limiting circular block 14 is provided on the upper side of the mounting base 1, a snap ring 15 is fixedly installed on one side of the second limiting circular block 14, a plug-in plate 16 is fixedly installed on one side of the snap ring 15, a pressing rod 17 is fixedly installed on both sides of the second limiting circular block 14, a second mounting tube 18 is fixedly installed on both sides of the mounting base 1, the pressing rod 17 is movably inserted in the second mounting tube 18, a third spring 19 is provided in the second mounting tube 18, the lower side of the pressing rod 17 is against the third spring 19, and the liquid collecting box 5 is fixedly mounted on both sides of the second limiting circular block 14.

The schematic diagram of this structure is as follows: Figure 2 、 Figure 3 and Figure 4 This structure allows the liquid collecting box 5 to be fixed on the second limiting circular block 14 by snapping. The second limiting circular block 14 itself can move up and down to a certain extent, so that the limiting ring 23 can be snapped into the air extraction groove 25, thereby completing the preliminary assembly of the liquid collecting box 5. This assembly is very quick and can save time during equipment assembly.

[0043] Furthermore, the lower end of the L-shaped tube 26 is opposite to the bottom surface of the liquid collecting box 5, and a guide block 27 is fixedly installed on the upper side of the liquid collecting box 5. An insertion ring 28 is fixedly installed on the upper side of the guide block 27, and the upper end of the insertion ring 28 is flush with the upper end of the limit ring 23. The schematic diagram of this structure is Figure 3 The shape of the L-shaped tube 26 can effectively prevent the splashing of the accumulated liquid when entering the liquid collection box 5, thereby preventing the accumulated liquid from contaminating the parts outside the liquid collection box 5 and improving the stability of the equipment.

Figure 4 The main function of the filter block 29 is to filter and effectively absorb impurities in the air during the operation of the vacuum pump 3, reducing the possibility of the vacuum pump 3 being contaminated by accumulated liquid, while also reducing the risk of other components being contaminated by accumulated liquid during long-term use. The filter block 29 is not fixedly installed in the vacuum tank 25, but is inserted into the vacuum tank 25 by squeezing the liquid collecting box 5, making it easy to disassemble.

[0045] Furthermore, the locking mechanism 6 also includes a first mounting block 602, a mounting shaft 603, a first connecting rod 605, a hollow knob 606, a first limiting round block 607, a first spring 608, a limiting spring 609 and a limiting ratchet 610.

The schematic diagram of this structure is as follows: Figure 7 and Figure 13 The arc-shaped stopper 604 is horn-shaped, narrow at one end and wide at the other. When rotated, it can press against the underside of the liquid collecting box 5 and exert an upward force on the liquid collecting box 5 through its own shape, ensuring stable communication between the liquid collecting box 5 and the air extraction groove 25. The limiting spring 609 is set at an angle, so that the hollow knob 606 can only rotate in one direction when rotated, thereby ensuring that the arc-shaped stopper 604 stably presses against the underside of the liquid collecting box 5. The user can release the limit by pulling the hollow knob 606 outward, which is simple to operate and easy to control.

[0046] Furthermore, the ventilation mechanism 7 includes a ventilation groove 701, a fixed arc piece 702, a movable arc piece 703, a sealing gasket 704, a first installation cylinder 705, a rotating rod 706 and a torsion spring 707.

The schematic diagram of this structure is as follows: Figure 4 and Figure 5After the use of the equipment is finished, the liquid collecting box 5 will still be adsorbed on the air extraction groove 25 due to the negative pressure. This structure is used to relieve the negative pressure in the liquid collecting box 5. The fixed arc piece 702 and the movable arc piece 703 are the same shape. Both are semicircular pieces with an angle of more than one hundred and twenty degrees. Under normal circumstances, the two cover each other to seal the ventilation groove 701. Rotating the rotating rod 706 can drive the movable arc piece 703 to rotate, so that the ventilation groove 701 is connected to the liquid collecting box 5, relieving the negative pressure in the liquid collecting box 5, and then completing the loading and unloading. There is no need to directly pull out the liquid collecting box 5, which reduces the possibility of agitation of the accumulated liquid during disassembly and improves the stability of the equipment.

The second movable groove 808 runs through the first movable groove 807. The front and rear sides of the first movable groove 807 are provided with limiting arc-shaped grooves 809. The size of the limiting arc-shaped grooves 809 matches the size of the limiting arc-shaped plate 806. A pulling block 810 is fixedly installed on the upper side of the air extraction rod 803. The upper mounting long plate 2 is provided with an air extraction hole 811. The air extraction hole 811 is opposite to the position of the air extraction groove 25, and the air extraction hole 811 is connected to the second ventilation pipe 802. The schematic diagram of this structure is as follows: Figure 4 、 Figure 6 and Figure 12 When the pumping rod 803 moves upward, negative pressure is generated within the pumping cylinder 801. Since the second vent pipe 802 is connected to the liquid collecting box 5, the air in the liquid collecting box 5 is extracted to form a negative pressure.

When holding the mounting tube 1102, the user can move their fingers to choose to turn the toggle lever 1112 or press the V-shaped pressure block 1203, which improves the convenience of using the device.

[0051] Working principle: When installing the liquid collecting box 5 of the present invention, first place the filter block 29 in the air extraction groove 25, press the second limiting circular block 14 downward, and then the pressing rod 17 moves in the second installation tube 18 and compresses the third spring 19, so that the insertion plate 16 is inserted into the insertion groove 22, and the clamping ring 15 is fitted into the annular clamping groove 21. Loosen the second limiting circular block 14, insert the limiting ring 23 into the air extraction groove 25, and the third sealing rubber ring 24 is tightly pressed against the lower side of the filter block 29. Then rotate the hollow knob 606, which drives the first limiting circular block 607 to rotate, and then drives the first connecting rod 605 to rotate, so that the installation shaft 603 and the arc-shaped block 604 rotate. The arc-shaped block 604 gradually fits against the bottom of the liquid collecting box 5 and squeezes upward, so that the liquid collecting box 5 and the air extraction groove 25 are connected and sealed, completing the installation and locking.

[0052] When removing the liquid collecting box 5, the rotating rod 706 drives the movable arc piece 703 to rotate so that it fits with the fixed arc piece 702, the ventilation groove 701 is unsealed, and the negative pressure in the liquid collecting box 5 disappears. The rotating rod 706 is released, and the movable arc piece 703 is reset and re-sealed under the action of the torsion spring 707. The subsequent disassembly steps are the opposite of the installation steps.

[0053] To connect the L-shaped tube 26 and the hose 10, insert the insertion tube 914 into the L-shaped tube 26. Under the magnetic attraction of the first and second magnets 901 and 909, and guided by the triangular block 905, the triangular block 905 snaps into the engagement groove 913, completing the connection. To disconnect, squeeze the pressing plate 908 relative to each other to disengage the triangular block 905 from the engagement groove 913, and remove the hose 10.

[0054] During use, hold the mounting tube 1102 and move the rotating rod 1112 with your fingers, which drives the second gear 1116 to rotate, and drives the hollow gear 1109 to rotate by engaging with the annular tooth groove 1110. The hollow gear 1109 then drives the rotating shaft 1105 to rotate by engaging with the first gear 1108, so that the dredging blade 1106 rotates to dredge the accumulated fluid.

[0055] When holding the mounting tube 1102, the V-shaped pressing block 1203 can be pressed, and its lower side squeezes the hose 10 to achieve closure, and the movable block 1206 is pushed to make it fit into the limit frame 1204 to complete the release and fixation. Due to the action of the second guide rod 1207, the movable block 1206 will not completely detach from the third movable groove 1205.

[0056] When the vacuum mechanism 8 is to be used, the pull block 810 is pulled upward, and the vacuum rod 803 drives the airtight rubber block 805 upward, and the vacuum cylinder 801 begins to pump air. The air in the liquid collection box 5 enters the vacuum cylinder 801 through the vacuum hole 811 and the second vent pipe 802, creating a negative pressure. At this time, the limiting arc piece 806 slides within the second movable groove 808. To fix the position of the vacuum rod 803, the vacuum rod 803 is rotated to insert the limiting arc piece 806 into the limiting arc groove 809. The reset operation is similar.
