Description

Technical Field

[0001] This utility model relates to the field of cardiovascular medicine technology, specifically to a clinical puncture device for cardiovascular medicine. Background Technology

[0002] In the field of clinical puncture in cardiovascular medicine, various puncture devices already exist in the current technology. For example, a patent (application number: 202411958285.X) jointly applied for by Fuwai Hospital of the Chinese Academy of Medical Sciences and Xinnopu Medical Technology (Beijing) Co., Ltd. discloses a pericardial puncture guidewire kit. This kit, through a special guidewire head design, allows the needle tip to deflect away from the inner wall of the pericardium during puncture and surround the needle tip in a fully bent shape, thereby effectively reducing the risk of continuous puncture of the pericardium and scratching of myocardial cells, and lowering the probability of surgical complications. However, this existing technology mainly optimizes the accuracy and safety of pericardial puncture, but still has certain limitations in terms of the overall function and ease of operation of the puncture device.

[0003] In actual clinical practice, pericardiocentesis not only needs to ensure the accuracy and safety of the puncture, but also requires consideration of the versatility and ease of operation of the puncture device. For example, when draining pericardial effusion, existing puncture devices typically require frequent replacement of different components (such as the puncture needle, guidewire, and catheter), and multiple adjustments to the device's connections during the puncture process. This not only increases the complexity of the procedure but may also prolong the puncture time, increasing the risk to the patient. Furthermore, existing puncture devices often require additional equipment or complex procedures for prolonged drainage, further limiting their flexibility and convenience in clinical application. Therefore, how to further improve the versatility and ease of operation of puncture devices while ensuring puncture accuracy and safety is a pressing technical problem that needs to be solved in the field of cardiovascular clinical puncture. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a clinical puncture device for cardiovascular medicine, which solves the problems mentioned in the background section.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a clinical puncture device for cardiovascular medicine, comprising a multi-port tube, the multi-port tube including a first tube segment, a multi-port connector, at least three second tube segments, and at least three stop plates; one end of the first tube segment is fixedly connected to one end of the multi-port connector and the two are internally interconnected, the other end of the multi-port connector is fixedly connected to the ends of each of the second tube segments, and the multi-port connector is connected to each of the second tube segments; each stop plate is fitted onto the outer wall of each of the second tube segments; the stop plate is a plate structure, and each stop plate has a through hole and a groove, the through hole and the groove being interconnected, the diameter of the through hole being larger than the width of the groove, and the diameter of the through hole being larger than the outer diameter of the second tube segment, the width of the groove being less than or equal to twice the wall thickness of the second tube segment; the stop plate is slidably connected to the second tube segment, and after the second tube segment slides on the stop plate, the second tube segment moves from the through hole to the groove, the stop plate squeezes the second tube segment and closes the internal flow channel of the second tube segment.

[0006] Optionally, it also includes a puncture needle, syringe, guidewire, catheter, waste collection bag, and drainage tube; the end of the first tube segment away from the multi-port connector is detachably connected to the puncture needle or catheter; the end of the second tube segment away from the multi-port connector is detachably connected to the syringe or drainage tube.

[0007] Optionally, the guidewire passes through the multi-channel tube and the puncture needle in sequence.

[0008] Optionally, the catheter is sleeved on the outer wall of the guidewire and the two are slidably connected, and the catheter slides along the length of the guidewire.

[0009] Optionally, one end of the drainage tube is inserted into the second pipe section, and the other end of the drainage tube is detachably connected to the waste liquid inflow port of the waste liquid collection bag.

[0010] (III) Beneficial Effects This invention provides a clinical puncture device for cardiovascular medicine, which has the following beneficial effects: 1. This clinical puncture device for cardiovascular medicine improves the versatility and ease of operation of existing puncture devices. By designing a novel multi-port tube structure, it effectively solves the problems of single-function and complex operation in existing technologies. The multi-port tube includes a first segment, a multi-port connector, at least three second segments, and at least three stop plates. This structural design allows the puncture device to perform multiple functions, such as puncture, injection, and drainage, within a single component, eliminating the need for frequent component replacements. For example, during pericardial effusion aspiration, the physician can directly connect the puncture needle and syringe through the multi-port tube, enabling continuous puncture and aspiration operations, significantly reducing the number of steps and time required. Furthermore, the stop plate design of the multi-port tube allows the physician to flexibly control the opening and closing of each second segment as needed, thereby switching between different functions and further improving the convenience and flexibility of operation. This improvement in versatility and ease of operation not only reduces patient discomfort but also enhances the safety and efficiency of the procedure.

[0011] 2. This clinical puncture device for cardiovascular medicine enables convenient operation of prolonged drainage. Another significant advantage of this clinical puncture device for cardiovascular medicine is its ability to facilitate prolonged drainage. In existing technologies, prolonged drainage usually requires additional equipment or complex procedures, which not only increases patient discomfort but may also lead to unexpected situations during drainage. This clinical puncture device for cardiovascular medicine, by designing multiple second segments and stop clips within a multi-port tube, allows physicians to directly connect the drainage tube to the multi-port tube without replacing components, and control the start and end of drainage through the stop clips. This design not only simplifies the drainage procedure but also reduces the risk of infection that may arise from component replacement. Furthermore, since the connection between the drainage tube and the multi-port tube is detachable, physicians can flexibly adjust the drainage time and frequency according to the patient's actual situation, further improving the flexibility and safety of the drainage operation. This convenient operation of prolonged drainage not only reduces the workload of medical staff but also improves patient comfort and treatment outcomes. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0017] Example 1, please refer to Figures 1 to 2 , Figures 7 to 9 The present invention provides a technical solution: a clinical puncture device for cardiovascular medicine, comprising a puncture needle 1, a multi-port tube 2, and a syringe 3.

[0018] One end of the multi-port tube 2 is detachably connected to the external end of the puncture needle 1 (including but not limited to using a plug-in connection), and the other end of the multi-port tube 2 is detachably connected to the Luer connector on the syringe 3 (including but not limited to using a plug-in connection).

[0019] This technical solution describes a clinical puncture device for cardiovascular medicine, used to perform pericardial effusion puncture on patients, to extract fluid from the patient's pericardium to relieve symptoms or perform fluid analysis.

[0020] In practice: the external end of the puncture needle 1 is connected to one end of the multi-port tube 2, and the other end of the multi-port tube 2 is connected to the Luer connector of the syringe 3.

[0021] The puncture needle 1 is inserted through the xiphoid process. The tip of puncture needle 1 enters below the xiphoid process, facing the left shoulder, at a 30° to 40° angle to the patient's skin. The needle is advanced slowly, initially perpendicularly for 1.5 to 2 cm, then changing direction and advancing parallel to the patient's skin for 2 to 4 cm until it contacts the pericardial wall. When the needle 1 passes through the pericardial wall and enters the pericardial cavity, the physician will feel a distinct sense of loss of resistance; at this point, the needle tip is inside the pericardial cavity.

[0022] The doctor draws out pericardial effusion by pulling the handle of syringe 3. The pericardial effusion flows sequentially through the puncture needle 1, the multi-perforation tube 2, and the syringe 3. Once the inflow of fluid is confirmed, the fluid is typically a yellow or dark red non-clotting fluid. After confirming the fluid is pericardial effusion, the doctor directly uses syringe 3 to aspirate the fluid. After the fluid aspiration is complete, the puncture needle 1 is withdrawn.

[0023] This first embodiment is suitable for patients with a small amount of pericardial effusion and is applicable when pericardial effusion puncture can remove pericardial effusion in a short time.

[0024] Example 2, please refer to Figures 1 to 10 The main difference between this embodiment and Embodiment 1 is that: a clinical puncture device for cardiovascular medicine also includes a guidewire 4, a catheter 5, a waste fluid collection bag 6, a drainage tube 7, and a receiving tube 8. The guidewire 4 is slidably placed inside the receiving tube 8, and the receiving tube 8 is used to hold the guidewire 4.

[0025] The multi-port pipe 2 includes a first pipe section 201, a multi-port connector 202, at least three second pipe sections 203, and at least three stop plates 204.

[0026] One end of the first pipe segment 201 is fixedly connected to one end of the multi-port connector 202 and the two are internally interconnected. The other end of the multi-port connector 202 is fixedly connected to the ends of each of the second pipe segments 203, and the multi-port connector 202 is connected to each of the second pipe segments 203.

[0027] Each of the aforementioned stop plates 204 is respectively fitted onto the outer wall of each of the second pipe sections 203. The stop plate 204 has a plate structure, and each stop plate 204 has a through hole 2041 and a sliding groove 2042, with the through hole 2041 communicating with the sliding groove 2042. The diameter of the through hole 2041 is larger than the width of the groove 2042, and the diameter of the through hole 2041 is larger than the outer diameter of the second pipe section 203. The width of the groove 2042 is less than or equal to twice the wall thickness of the second pipe section 203.

[0028] The stop plate 204 is slidably connected to the second pipe section 203. After the second pipe section 203 slides on the stop plate 204, it moves from the through hole 2041 to the groove 2042. The stop plate 204 squeezes the second pipe section 203 and closes the internal flow channel of the second pipe section 203.

[0029] Each second pipe section 203 is equipped with a stop plate 204, which is used to control the opening and closing of the second pipe section 203. The second pipe section 203 is a flexible tube, and the stop plate 204 is made of hard plastic with a certain thickness to prevent it from scratching the second pipe section 203. By pushing and moving the second pipe section 203 relative to each other, the second pipe section 203 moves from the through hole 2041 to the slide groove 2042. The stop plate 204 compresses the pipe wall of the second pipe section 203, thereby causing the pipe wall of the second pipe section 203 to fit together, and the internal flow channel of the second pipe section 203 is in a closed state, thus closing the second pipe section 203. By pushing and moving the second pipe section 203 relative to each other, the second pipe section 203 is moved from the slide groove 2042 to the through hole 2041. The stop plate 204 no longer squeezes the pipe wall of the second pipe section 203, thereby resetting the pipe wall of the second pipe section 203. The internal flow channel of the second pipe section 203 is in an open state, thus enabling the second pipe section 203 to be opened.

[0030] Specifically, the end of the first tube segment 201 away from the multi-port connector 202 is detachably connected to the puncture needle 1 or the catheter 5.

[0031] The end of the first tube segment 201 furthest from the multi-port connector 202 is detachably connected to the external end of the puncture needle 1 (including but not limited to insertion). The end of the first tube segment 201 furthest from the multi-port connector 202 is detachably connected to the external end of the catheter 5 (including but not limited to insertion).

[0032] The end of the second tube segment 203 away from the multi-port connector 202 is detachably connected to the syringe 3 or the drainage tube 7.

[0033] The end of the second tubing segment 203 furthest from the multi-port connector 202 is detachably connected to the syringe 3 (including but not limited to a plug-in connection). The end of the second tubing segment 203 furthest from the multi-port connector 202 is detachably connected to the drainage tube 7 (including but not limited to a plug-in connection).

[0034] Specifically, the guidewire 4 passes through the multi-port tube 2 and the puncture needle 1 in sequence. The catheter 5 is sleeved on the outer wall of the guidewire 4 and the two are slidably connected, and the catheter 5 slides along the length of the guidewire 4. One end of the drainage tube 7 is inserted into the second tube segment 203, and the other end of the drainage tube 7 is detachably connected to the waste liquid inflow port of the waste liquid collection bag 6 (including but not limited to insertion).

[0035] The drainage tube 7 serves to drain and transport the accumulated liquid. The waste liquid collection bag 6 is used to collect and hold the accumulated liquid.

[0036] This second embodiment can be used as a further implementation of the first embodiment to meet the need for long-term drainage of effusion during pericardial effusion puncture.

[0037] In practice: the patient is positioned sitting or semi-recumbent, the area is disinfected, and local anesthesia is administered. (Reference) Figure 1 , Figure 2 , Figure 7 The doctor inserts the end of the first tubing segment 201 furthest from the multi-port connector 202 into the external end of the puncture needle 1, and inserts the end of a second tubing segment 203 furthest from the multi-port connector 202 into the Luer connector of the syringe 3, thus opening the internal flow channel of this second tubing segment 203. The flow channels of the other second tubing segments 203 are then closed.

[0038] The puncture needle 1 is inserted through the xiphoid process. The tip of puncture needle 1 enters below the xiphoid process, facing the left shoulder, at a 30° to 40° angle to the patient's skin. The needle is advanced slowly, initially perpendicularly for 1.5 to 2 cm, then changing direction and advancing parallel to the patient's skin for 2 to 4 cm until it contacts the pericardial wall. When the needle 1 passes through the pericardial wall and enters the pericardial cavity, the physician will feel a distinct sense of loss of resistance; at this point, the needle tip is inside the pericardial cavity.

[0039] The doctor draws out pericardial effusion by pulling the handle of syringe 3. The pericardial effusion flows sequentially through the puncture needle 1, the multi-perforation tube 2, and the syringe 3. Once the fluid flow is confirmed, it is confirmed to be a yellow or dark red non-clotting fluid. After the fluid has flowed into syringe 3, the flow path of the second tubing segment 203 corresponding to syringe 3 is closed. Syringe 3 is then removed, and the doctor verifies the nature of the fluid by observing whether it has coagulated (pericardial fluid usually does not coagulate) or by using gauze to verify its properties (e.g., a dark red spot in the center surrounded by a light red halo indicates pericardial effusion).

[0040] After confirming the fluid level, the pericardial effusion can be directly aspirated using syringe 3.

[0041] When prolonged continuous drainage is required: reinsert the Luer connector of syringe 3 into the first second tubing segment 203; refer to Figure 3 , Figure 4 Open the stop plate 204 on the second second tube segment 203, align one end of the receiving tube 8 with the port of the second second tube segment 203, and slide the guidewire 4 so that it slides sequentially through the multi-port tube 2 and the puncture needle 1, with the tip of the guidewire 4 inserted into the pericardial cavity. Then, the doctor uses surgical forceps or their hand to hold the end of the guidewire 4 (i.e., the exposed end) to prevent it from slipping and from being removed from the patient's body. The doctor slowly slides the puncture needle 1, slowly withdrawing it from the patient's body.

[0042] After removing the puncture needle 1 from the patient's body, remove the puncture needle 1 from the multi-port catheter 2, and connect the external end of the catheter 5 to the first segment 201. The catheter 5 is a flexible tube with a certain degree of flexibility. Insert the end of the guidewire 4 into the head (internal end) of the catheter 5, and hold the catheter 5, allowing it to slide along the guidewire 4 from the end to the head, as per reference. Figure 5 During the displacement process, the catheter 5 is inserted into the patient's body along the guide wire 4 until the tip of the catheter 5 is inserted into the patient's pericardial cavity.

[0043] refer to Figure 6 The guidewire 4 is withdrawn and detached from the pericardial cavity. The guidewire 4 is then moved sequentially to remove the second second segment 203 of the catheter 5 and the multi-perforation tube 2. After the guidewire 4 is removed, the second second segment 203 is closed. The doctor then connects both ends of the drainage tube 7 to the waste fluid collection bag 6 and the third second segment 203, respectively.

[0044] Open the first and third second tubing segments 203, pull the handle of syringe 3, and the pericardial effusion flows sequentially through catheter 5 and multi-port tube 2 into syringe 3. Under the drainage effect of syringe 3, most of the remaining pericardial effusion flows sequentially through catheter 5, multi-port tube 2, and drainage tube 7 into waste fluid collection bag 6. This allows for continuous drainage of pericardial effusion for an extended period. Replacing the puncture needle 1 with catheter 5, which is relatively flexible, avoids damage to the patient's tissues caused by prolonged operation.

[0045] The needle insertion and fluid aspiration processes must be slow to avoid damage to the heart or surrounding tissues. An electrocardiogram (ECG) or ultrasound can be used during the procedure to ensure the correct needle placement. Rapid fluid aspiration should be avoided as it can lead to acute ventricular dilation or pulmonary edema.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
