Description

Technical Field

[0001] The invention relates to the technical field of puncture devices, in particular to a clinical puncture device for cardiovascular medicine. Background Art

[0002] The diseases that the Department of Cardiology mainly treats include angina pectoris and hypertension, and the treatment methods of the Department of Cardiology mainly include drug therapy, interventional therapy and cardiac rehabilitation. Cardiovascular puncture is a diagnostic and treatment technique that inserts a puncture needle into the body cavity to extract secretions for testing, inject gas or contrast agent into the body cavity for angiography, or inject drugs into the body cavity. The purpose of puncture is to draw blood for testing, blood transfusion, infusion and insert a catheter for angiography.

[0003] However, during current cardiovascular treatment, puncture technology is used to aspirate the fluid in the cardiovascular system and inject drugs. When injecting drugs and aspirating the fluid near the cardiovascular system, two syringe barrels are combined to aspirate and inject drugs. The two barrels are connected to a needle, and one of the two barrels aspirates the fluid and the other injects the drug. There is no discharge mechanism on the barrel responsible for aspirating the fluid. When the patient has a lot of fluid accumulation, the fluid inside the barrel of the syringe needs to be discharged and then drawn out. If there is no discharge mechanism, the syringe needs to be separated from the needle. When disassembling the syringe, the needle needs to be pressed vertically on the patient's body, which increases the patient's pain. In addition, the two barrels are combined together, and the end of the barrel used to aspirate the fluid when aspirating drugs multiple times is prone to contaminate the injection barrel, affecting the efficacy of the drug and even causing cross infection. Summary of the invention

[0004] In view of the problems in the prior art, the present invention provides a clinical puncture device for cardiovascular medicine.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a clinical puncture device for cardiovascular medicine, comprising a needle and a conversion mechanism installed on the needle, a first syringe and a suction mechanism installed on the conversion mechanism, a discharge mechanism installed on the suction mechanism, and a limiting mechanism installed on the conversion mechanism; the conversion mechanism comprises a base, a side of the needle is fixedly connected to the base, a rotating shaft is rotatably connected to the base, a fixing plate is fixedly connected to the rotating shaft, a lower sealing gasket is installed on the needle, two connecting ports are symmetrically provided on the fixing plate about the rotating shaft, two upper sealing gaskets are bonded to the bottom of the fixing plate relative to the rotating shaft, one of the upper sealing gaskets is in contact with the lower sealing gasket, two connectors are symmetrically fixedly connected to the fixing plate about the rotating shaft, the first syringe is connected to one of the connectors, and the suction mechanism is connected to the other connector.

[0006] Specifically, the suction mechanism includes a second syringe, and the second syringe is connected to the connecting head located on the top of the lower sealing gasket.

[0007] Specifically, the suction mechanism further includes a first valve, and the second syringe is equipped with the first valve.

[0008] Specifically, the limiting mechanism includes a fixed column, the lower sealing gasket is fixedly connected to the fixed column, the fixed column is slidably connected to a limiting plate, two limiting grooves are relatively opened on both sides of the fixed plate, and the limiting plate is inserted into one of the limiting grooves.

[0009] Specifically, the limiting mechanism further includes a spring, and the spring is clamped between the limiting plate and the lower sealing gasket.

[0010] Specifically, the first syringe and the second syringe are equal in size, and the cross-section of the connector located at the bottom of the first syringe and the second syringe is a convex-shaped structure.

[0011] Specifically, the discharge mechanism includes a discharge pipe and a second valve. The bottom of the second syringe is connected to the discharge pipe, and the second valve is installed on the discharge pipe.

[0012] Specifically, the drainage mechanism further includes a connecting pipe, and the drainage pipe is connected to the connecting pipe.

[0013] Specifically, a control piece is installed on the needle head, and two control pieces are relatively fixedly connected to the needle head.

[0014] The beneficial effects of the present invention are:

[0015] (1) The clinical puncture device for cardiovascular medicine described in the present invention has a conversion mechanism installed on the needle. When it is necessary to absorb the accumulated fluid in the patient's cardiovascular lesion, one of the upper gaskets can be brought into contact with the lower gasket on the needle, and the second syringe can be connected to the connector. The discharge mechanism is closed and the valve is opened. The accumulated fluid in the patient's affected area can then be absorbed through the second syringe. When injecting the drug, the drug is first absorbed inside the second syringe. It only needs to rotate the fixed plate 180 degrees to rotate the first syringe to the top of the lower gasket, so that the first syringe and the second syringe can be quickly swapped. There is no need to press the needle in the vertical direction to disassemble the second syringe and replace the first syringe, thereby alleviating the patient's pain.

[0016] (2) The clinical puncture device for cardiovascular medicine described in the present invention has a limiting mechanism on the lower sealing gasket. The fixing plate can be limited by the limiting mechanism whether it is when injecting drugs into the patient or sucking out the accumulated fluid. When limiting the fixing plate, it is only necessary to engage the limiting groove on one side of the fixing plate through the limiting plate to achieve horizontal limiting of the fixing plate. When the fixing plate needs to be rotated, the limiting plate on the fixing column is pulled, and the limiting plate passes over the fixing plate. After the fixing plate rotates, the limiting plate is released. The limiting plate is engaged with the inside of another limiting groove under the tension of the spring, and the fixing plate can be quickly limited to avoid horizontal rotation, which causes the upper sealing gasket and the lower sealing gasket to be misaligned and affect water leakage, thereby facilitating drug injection and liquid suction.

[0017] (3) In the clinical puncture device for cardiovascular medicine described in the present invention, a discharge mechanism is installed at the bottom of the suction mechanism. When the suction mechanism is used to absorb the accumulated fluid from the patient's affected part, the second valve can be closed. At this time, the second syringe will not leak and can absorb the accumulated fluid from the patient's affected part. After the second syringe is full, the first valve at the bottom of the second syringe can be closed, and the second valve on the discharge pipe can be opened to push the second syringe to discharge the accumulated fluid from the connecting pipe. The second syringe can be discharged without disassembling the second syringe, thereby increasing the comfort of the patient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] 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.

[0028] like Figure 1-Figure 7As shown, a clinical puncture device for cardiovascular medicine described in the present invention comprises a needle 1, a conversion mechanism 3 installed on the needle 1, a first syringe 4 and a suction mechanism 5 are installed on the conversion mechanism 3, a liquid discharge mechanism 6 is installed on the suction mechanism 5, and a limiting mechanism 7 is installed on the conversion mechanism 3; the conversion mechanism 3 comprises a base 301, a side of the needle 1 is fixedly connected to the base 301, a rotating shaft 307 is rotatably connected to the base 301, a fixing plate 302 is fixedly connected to the rotating shaft 307, a lower sealing pad 306 is installed on the needle 1, and two connecting ports 306 are symmetrically provided on the fixing plate 302 about the rotating shaft 307. 5, two upper sealing pads 304 are bonded relatively to the bottom of the fixing plate 302 about the rotating shaft 307, one of the upper sealing pads 304 is in contact with the lower sealing pad 306, two connectors 303 are fixedly connected symmetrically on the fixing plate 302 about the rotating shaft 307, the first syringe 4 is connected to one of the connectors 303, and the suction mechanism 5 is connected to the other connector 303; the suction mechanism 5 includes a second syringe 501, and the connector 303 located on the top of the lower sealing pad 306 is connected to the second syringe 501; a control sheet 2 is installed on the needle 1, and two control sheets 2 are fixedly connected relatively to the needle 1; When sucking the accumulated fluid from the patient's affected part, the fixing plate 302 is rotated to the top of the needle 1, and one of the connecting ports 305 corresponds to the needle 1. At this time, one of the upper sealing pads 304 located at the bottom of the fixing plate 302 is tightly fitted with the lower sealing pad 306 on the needle 1 without leakage. The second valve 603 on the drainage pipe 601 is closed to prevent air from entering from the drainage pipe 601. The needle 1 is inserted into the patient's body, and the second syringe 501 is pulled to extract the accumulated fluid from the patient's affected part, and the cleaning of the accumulated fluid is completed. After the cleaning is completed, the fixing plate 302 is rotated 180 degrees to swap the positions of the first syringe 4 and the second syringe 501. The medicine inside the first syringe 4 can be first sucked up and then connected to the connector 303. After the fixing plate 302 is rotated one hundred and eighty degrees, the first syringe 4 is connected to the needle 1. Similarly, the other upper sealing gasket 304 will fit with the lower sealing gasket 306 on the needle 1. The first syringe 4 can be pushed to push the medicine inside it through the needle 1 to the patient's affected part for treatment. The design of the two upper sealing gaskets 304 can ensure that the first syringe 4 to the top of the needle 1 is in a clean state. When sucking liquid, the accumulated liquid is sucked into the second syringe 501, so there will be no residual accumulated liquid at the needle 1, and the contact between the drug and the accumulated liquid is minimized to avoid cross infection.

[0029] Specifically, Figure 4 , Figure 6 and Figure 7As shown, the limiting mechanism 7 includes a fixing column 701, the fixing column 701 is fixedly connected to the lower sealing gasket 306, and a limiting plate 702 is slidably connected to the fixing column 701. Two limiting grooves 704 are relatively provided on both sides of the fixing plate 302, and the limiting plate 702 is inserted into one of the limiting grooves 704; the limiting mechanism 7 also includes a spring 703, and the spring 703 is clamped between the limiting plate 702 and the lower sealing gasket 306; whether it is sucking the accumulated fluid from the patient's affected part or injecting the medicine, the fixing plate 302 can be limited by the limiting plate 702 in cooperation with the limiting groove 704, and the fixing plate 302 is rotated to the needle head during operation. 1, it is necessary to pull the limit plate 702 to prevent the limit plate 702 from blocking the rotation of the fixed plate 302. After the fixed plate 302 is rotated to the top of the needle head 1, observe whether the upper sealing pad 304 and the lower sealing pad 306 on the needle head 1 are tightly in contact. After the two are matched, the limit plate 702 can be loosened to realize the contraction of the spring 703. Further, the limit plate 702 is engaged with the inside of the limit groove 704 on the side of the fixed plate 302 and the upper sealing pad 304 to limit the horizontal direction of the fixed plate 302, so as to avoid the rotation of the fixed plate 302 during liquid aspiration or drug injection, causing the upper sealing pad 304 and the lower sealing pad 306 to be misaligned and cause water leakage, resulting in pollution to other parts of the body or waste of drugs.

[0030] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the suction mechanism 5 also includes a first valve 502, and the first valve 502 is installed on the second syringe 501; the first syringe 4 and the second syringe 501 are equal in size, and the cross-section of the connector 303 located at the bottom of the first syringe 4 and the second syringe 501 is a convex structure; the discharge mechanism 6 includes a discharge pipe 601 and a second valve 603, the bottom of the second syringe 501 is connected to the discharge pipe 601, and the second valve 603 is installed on the discharge pipe 601; the discharge mechanism 6 also includes a connecting pipe 602, and the discharge pipe 601 is connected to a connecting pipe Connect the pipe 602; when sucking the accumulated fluid in the patient's body, rotate the second syringe 501 to the top of the needle 1. When discharging the accumulated fluid in the second syringe 501, the second valve 603 on the discharge pipe 601 can be opened to push the second syringe 501 to discharge the accumulated fluid from the discharge pipe 601. A connecting pipe 602 is installed at the end of the discharge pipe 601. It is only necessary to switch the second valve 603 to achieve multiple suction of the accumulated fluid in the patient's body and discharge of the accumulated fluid in the second syringe 501. There is no need to repeatedly separate the second syringe 501 from the connector 303, thereby reducing the patient's pain.

[0031] When the present invention is used, first, when sucking the accumulated fluid from the patient's affected part, the fixing plate 302 is rotated to the top of the needle 1, and one of the connecting ports 305 corresponds to the needle 1. At this time, one of the upper sealing pads 304 located at the bottom of the fixing plate 302 is tightly fitted with the lower sealing pad 306 on the needle 1 without leaking air, and the second valve 603 on the drainage pipe 601 is closed to prevent air from entering from the drainage pipe 601. The needle 1 is inserted into the patient's body, and the second syringe 501 is pulled to extract the accumulated fluid from the patient's affected part, and the cleaning of the accumulated fluid is completed. After the cleaning is completed, the fixing plate 302 is rotated 180 degrees to realize the connection between the first syringe 4 and the second syringe 501. The positions of the two upper gaskets 304 are reversed, and the medicine inside the first syringe 4 can be sucked out first and then connected to the connector 303. After the fixing plate 302 is rotated 180 degrees, the first syringe 4 is connected to the needle 1. Similarly, the other upper gasket 304 will fit with the lower gasket 306 on the needle 1. The first syringe 4 can be pushed to push the medicine inside through the needle 1 to the patient's affected part for treatment. The design of the two upper gaskets 304 can ensure that the first syringe 4 to the top of the needle 1 is in a clean state. When sucking liquid, the accumulated liquid is sucked into the second syringe 501, so there will be no residual accumulated liquid at the needle 1, which minimizes the contact between the medicine and the accumulated liquid to avoid cross infection.

[0032] Then, whether it is to absorb the accumulated fluid from the patient's affected area or to inject medicine, the fixing plate 302 can be limited by the limiting plate 702 in cooperation with the limiting groove 704. During operation, when the fixing plate 302 rotates to the top of the needle 1, it is necessary to pull the limiting plate 702 to prevent the limiting plate 702 from blocking the rotation of the fixing plate 302. After the fixing plate 302 is rotated to the top of the needle 1, it is observed whether the upper sealing pad 304 and the lower sealing pad 306 on the needle 1 are tightly in contact. After the two are matched, the limiting plate 702 can be loosened to realize the contraction of the spring 703. Further, the limiting plate 702 is engaged with the fixing plate 302 and the inner part of the limiting groove 704 on the side of the upper sealing pad 304 to realize the horizontal limitation of the fixing plate 302, so as to avoid the upper sealing pad 304 and the lower sealing pad 306 from being misaligned and leaking due to the rotation of the fixing plate 302 during the suction or injection of liquid, thereby causing pollution to other parts of the body or waste of medicine.

[0033] Finally, after sucking out the accumulated fluid in the patient's body, the second syringe 501 can be rotated to the top of the needle 1. When discharging the accumulated fluid in the second syringe 501, the second valve 603 on the discharge tube 601 can be opened to push the second syringe 501 to discharge the accumulated fluid inside it from the discharge tube 601. A connecting tube 602 is installed at the end of the discharge tube 601. The accumulated fluid in the patient's body can be sucked out and the accumulated fluid in the second syringe 501 can be discharged multiple times only by switching the second valve 603. There is no need to repeatedly separate the second syringe 501 from the connector 303, thereby reducing the patient's pain.
