Description

Technical Field

[0001] The utility model relates to the medical field, and more specifically, to a clinical puncture device for cardiology. Background Art

[0002] Cardiology, also known as cardiovascular medicine, is a clinical department set up in the general internal medicine department of hospitals at all levels for the diagnosis and treatment of cardiovascular diseases. The diseases treated include angina pectoris, hypertension, sudden death, arrhythmia, heart failure, cardiomyopathy, myocarditis, acute myocardial infarction and other cardiovascular diseases. During clinical surgery in the Department of Cardiology, radial artery puncture is a key step in interventional diagnosis and treatment.

[0003] In clinical puncture in the Department of Cardiology, local anesthesia is usually first performed on the radial artery on the patient's wrist, and then the puncture needle is used to puncture the patient's radial artery at a certain angle. Gauze is placed on the patient's wrist, and the puncture needle is returned. When blood gushes out of the puncture needle, it means that the puncture needle has pierced the radial artery. Then a guide wire is inserted through the puncture needle, and then the puncture needle is pulled out, and the puncture site is opened. Then the sheath is inserted through the guide wire, and the guide wire is pulled out. Finally, the contrast catheter is inserted through the sheath, and contrast fluid is injected for contrast imaging. , and then complete the puncture angiography link of the entire cardiology clinical operation. In the whole link, the radial artery puncture step is the most difficult to grasp. It is necessary to find the radial artery and puncture the radial artery at a certain angle.

[0018] 3. Beneficial effects

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] 1. In this solution, after turning on the near-infrared generating module, the doctor places the auxiliary puncture mechanism on the patient's radial artery with one hand and keeps the auxiliary puncture mechanism stable. At this time, the sterile transparent developing film at the lower end of the auxiliary puncture mechanism is in contact with the skin above the patient's radial artery. The near-infrared light emitted by the near-infrared generating module is transmitted to the sterile transparent developing film through the near-infrared low-hydroxyl optical fiber. The near-infrared light is refracted by the amplifying refractive mirror in the sterile transparent developing film. A part of it is directly refracted on the skin, and the other part is refracted on the nano-reflective layer. The near-infrared light refracted on the nano-reflective layer will be reflected on the skin to prevent the near-infrared light from escaping to the outside world. According to the principle that hemoglobin in the blood absorbs near-infrared light more strongly than other tissues, the near-infrared light transmitted by the sterile transparent developing film can project the radial artery and other blood vessels on the skin, so that the doctor can quickly find the radial artery, and transmit the near-infrared light through the sterile transparent developing film and the near-infrared low-hydroxyl optical fiber. The doctor's body position will not block the projection of the near-infrared light, and the volume is small, which will not affect the doctor's subsequent operation.

[0021] 2. In this solution, the doctor places the auxiliary puncture mechanism on the patient's radial artery with one hand and keeps the auxiliary puncture mechanism stable. The doctor's thumb and index finger are pinched at the hand contact block, and the other hand pinches the upper end of the puncture needle. The puncture needle is moved according to the imaging position of the radial artery. The puncture needle will drive the limit block to move at the same time during the movement. When the puncture needle moves to the position of the radial artery and rotates a certain angle to prepare for puncture, the doctor's thumb and index finger pinch and press the hand contact block, and the hand contact block will drive the pressure rod to push the squeezing block. The squeezing block will squeeze the elastic gas during the advancement process. The bag contacts and presses against the shaft column, and the shaft column that is pressed against with a certain force is not easy to rotate, thereby limiting the angle of the puncture needle. After the internal gas of the squeezed elastic air bag is transmitted to the cavity inside the movable rod through the through hole on the shaft column, the rubber membrane will expand. The expanded rubber membrane will be clamped on both sides of the limit block, thereby limiting the puncture needle that passes through the limit block. When the position and angle of the puncture needle are limited, when the personnel pinches the puncture needle for puncture, even if the hand shakes, it will not cause the needle tip of the puncture needle to deviate, greatly improving the success rate of radial artery puncture.

[0022] 3. The auxiliary puncture mechanism and the sterile transparent developing film of this scheme are an integrated component. The overall structure is small and compact, which is convenient for doctors to use clinically. With the cooperation of the auxiliary puncture mechanism and the sterile transparent developing film, it is convenient for doctors to quickly find the radial artery and perform stable puncture, which improves the success rate of radial artery puncture and reduces trial and error to avoid harm to patients and unnecessary medical disputes. It also has a profound impact on the transition of doctors who are performing clinical surgery for the first time or who lack clinical surgery experience in clinical surgery.

[0037] Example:

[0038] See also Figure 1-9 A clinical puncture device for cardiology, comprising a puncture needle 1 and a near infrared generating module 3, the outer circumference of the puncture needle 1 is sleeved with an auxiliary puncture mechanism 2, and the lower end of the auxiliary puncture mechanism 2 is fixedly connected with a sterile transparent developing film 4;

[0039] The near-infrared output end of the near-infrared generating module 3 is fixedly connected with a light shield 31, one end of the light shield 31 is fixedly connected with a plurality of near-infrared low-hydroxyl optical fibers 32, one end of the near-infrared low-hydroxyl optical fibers 32 is fixedly connected with a connecting block 33, and the connecting block 33 is embedded in the lower end of the auxiliary puncture mechanism 2 and connected with the sterile transparent developing film 4;

[0040] During use of the present solution, the auxiliary puncture mechanism 2 and the sterile transparent developing film 4 are an integrated component, and the overall structure is small and compact, which is convenient for doctors to use clinically. With the cooperation of the auxiliary puncture mechanism 2 and the sterile transparent developing film 4, it is convenient for doctors to quickly find the radial artery and perform stable puncture, thereby improving the success rate of radial artery puncture and reducing trial and error, so as to avoid harm to patients and unnecessary medical disputes. It also has a profound impact on the transition of doctors who are performing clinical surgery for the first time or who lack clinical surgery experience in clinical surgery.

[0041] In order to better express the schematic diagram, the near-infrared low-hydroxyl optical fiber 32 in the figure is drawn shorter. In fact, the near-infrared low-hydroxyl optical fiber 32 is longer, and the near-infrared generating module 3 is placed beside the operating table.

[0042] See also Figure 1-5 The sterile transparent developing film 4 includes a transparent film layer 41, a magnifying refracting mirror 42 and a nanometer reflective layer 43. A magnifying refracting mirror 42 is provided on one side of the transparent film layer 41. The magnifying refracting mirror 42 corresponds to the near-infrared low-hydroxyl optical fiber 32 one by one. The upper surface of the transparent film layer 41 is provided with a nanometer reflective layer 43.

[0043] During the use of this solution, after turning on the near-infrared generating module 3, the doctor places the auxiliary puncture mechanism 2 on the patient's radial artery with one hand and keeps the auxiliary puncture mechanism 2 stable. At this time, the sterile transparent developing film 4 at the lower end of the auxiliary puncture mechanism 2 is in contact with the skin above the patient's radial artery. The near-infrared light emitted by the near-infrared generating module 3 is transmitted to the sterile transparent developing film 4 through the near-infrared low-hydroxyl optical fiber 32. The near-infrared light is refracted by the amplifying refractive mirror 42 in the sterile transparent developing film 4. A part of the near-infrared light is refracted directly on the skin, and the other part is refracted on the nano-reflector. On layer 43, the near-infrared light refracted on the nano-reflective layer 43 will be reflected on the skin to prevent the near-infrared light from escaping to the outside. According to the principle that hemoglobin in the blood absorbs near-infrared light stronger than other tissues, the near-infrared light transmitted by the sterile transparent developing film 4 can project the radial artery and other blood vessels on the skin, so that the doctor can quickly find the radial artery, and the near-infrared light is transmitted through the sterile transparent developing film 4 and the near-infrared low-hydroxyl optical fiber 32. The doctor's body position will not block the projection of the near-infrared light, and the small size will not affect the doctor's subsequent operations.

[0044] See also Figure 6-9The auxiliary puncture mechanism 2 includes an auxiliary frame 21, a movable rod 22, a limit block 23, a shaft column 24, a bearing 25, an elastic air bag 26, an extrusion block 27, a pressure rod 28 and a hand contact block 29. Both ends of the movable rod 22 are fixedly connected to the shaft column 24, the outer circumferential surface of the shaft column 24 is fixedly connected to the bearing 25, the outer circumferential surface of the bearing 25 is fixed to the auxiliary frame 21, the side of the shaft column 24 away from each other is fixedly connected to the elastic air bag 26, the side of the elastic air bag 26 away from each other is fixedly connected to the extrusion block 27, the pressure rod 28 runs through both sides of the auxiliary frame 21 and contacts with the extrusion block 27, and the end of the pressure rod 28 away from each other is fixedly connected to the hand contact block 29, the movable rod 22 is slidably connected to the limit block 23, and the limit block 23 is sleeved on the outer circumferential surface of the puncture needle 1;

[0045] During use of this solution, the doctor places the auxiliary puncture mechanism 2 on the patient's radial artery with one hand, and while keeping the auxiliary puncture mechanism 2 stable, the doctor's thumb and index finger pinch the hand contact block 29, and the other hand pinches the upper end of the puncture needle 1 to move the puncture needle 1 according to the imaging position of the radial artery. During the movement, the puncture needle 1 will drive the limit block 23 to move at the same time. When the puncture needle 1 moves to the position of the radial artery and rotates a certain angle to prepare for puncture, the doctor's thumb and index finger pinch and press the hand contact block 29, and the hand contact block 29 will drive the pressure rod 28 to push the squeezing block 27. During the pushing process, the squeezing block 27 will contact the solid shaft column 24. The solid shaft column 24 is not easy to rotate under a certain force, thereby limiting the angle of the puncture needle 1.

[0046] See also Figure 6-7 The inner wall of the movable rod 22 is provided with a slide groove 221, and sliders 231 are fixedly connected to both sides of the limit block 23, and the limit block 23 moves linearly in the slide groove 221 through the sliders 231;

[0047] During use of the present invention, the movement of the limit block 23 is limited by the slide groove 221 and the slider 231, so that the limit block 23 will not fall off the movable rod 22 during the movement, thereby improving the stability of the limit block 23 during the movement.

[0048] See also Figure 6-9 A cavity 222 is formed in the movable rod 22, a through hole 241 is formed on the surface of the shaft column 24, the elastic airbag 26 is connected to the cavity 222 in the movable rod 22 through the through hole 241 on the shaft column 24, and the cavity 222 and the slide groove 221 are separated by a rubber membrane 223;

[0049] During use of the present solution, the doctor's thumb and index finger pinch and press the hand contact block 29, which will drive the pressure rod 28 to push the squeezing block 27. The pressure block 27 will squeeze the elastic airbag 26 during the pushing process. The internal gas of the squeezed elastic airbag 26 is transmitted to the cavity 222 inside the movable rod 22 through the through hole 241 on the shaft column 24, which will cause the rubber membrane 223 to expand. The expanded rubber membrane 223 will be clamped on both sides of the limit block 23, thereby limiting the puncture needle 1 that passes through the limit block 23. When the position and angle of the puncture needle 1 are limited, when the personnel pinches the puncture needle 1 for puncture, even if the hand shakes, it will not cause the needle tip part of the puncture needle 1 to deviate, thereby greatly improving the success rate of radial artery puncture.

[0050] See also Figure 2-3 A pair of ear blocks 5 are fixedly connected to the lower end of the auxiliary puncture mechanism 2, and slots 331 are provided at both ends of the connecting block 33, and the ear blocks 5 match the slots 331;

[0051] During use of this solution, the auxiliary puncture mechanism 2 and the sterile transparent developing film 4 are an integrated component. In order to ensure medical hygiene, it is a disposable product. The auxiliary puncture mechanism 2 can be connected to the connecting block 33 at one end of the infrared generating module 3 by fitting the ear block 5 and the slot 331. After use, the auxiliary puncture mechanism 2 can be easily disassembled. Similarly, it is also convenient to install during use.

[0052] See also Figure 1-2 The outer circumferential surface of the pressure rod 28 is fixedly connected to the limiting ring 281, and the inner walls of the through holes 211 on both sides of the auxiliary frame 21 are fixedly connected to the limiting ring 1 212;

[0053] During use of this solution, the pressure rod 28 is limited by the limiting ring 1 212 and the limiting ring 281, so that the pressure rod 28 will not fall off from the auxiliary frame 21 during use.

[0054] See also Figure 3 The length, width and height of the auxiliary frame 21 are 30mm*25mm*5mm;

[0055] During use of the present invention, the width of an adult's open mouth is at least 10 cm. The auxiliary frame 21 of this specification is very convenient for doctors to pinch and press with their thumb and index finger, making it easy for doctors to operate and use.

[0056] See also Figure 1-2 A rubber extrusion layer 51 is fixedly connected to one side of the ear block 5, and the rubber extrusion layer 51 is in close contact with the inner wall of the notch 331;

[0057] During use of this solution, when the ear block 5 is engaged with the notch 331 , the rubber extrusion layer 51 can greatly increase the friction between the ear block 5 and the notch 331 , thereby improving the stability of the ear block 5 and the notch 331 when engaged.

[0058] In the utility model, the relevant technology first turns on the near-infrared generating module 3, and the doctor places the auxiliary puncture mechanism 2 on the patient's radial artery with one hand, and keeps the auxiliary puncture mechanism 2 stable. At this time, the sterile transparent developing film 4 at the lower end of the auxiliary puncture mechanism 2 is in contact with the skin above the patient's radial artery, and the near-infrared light emitted by the near-infrared generating module 3 is transmitted to the sterile transparent developing film 4 through the near-infrared low-hydroxyl optical fiber 32. The near-infrared light is refracted by the amplifying refractive mirror 42 in the sterile transparent developing film 4, and a part of it is refracted directly on the skin, and the other part is refracted at the nanometer. On the reflective layer 43, the near-infrared light refracted on the nano-reflective layer 43 will be reflected on the skin to prevent the near-infrared light from escaping to the outside. According to the principle that hemoglobin in the blood absorbs near-infrared light more strongly than other tissues, the near-infrared light transmitted by the sterile transparent developing film 4 can project the radial artery and other blood vessels on the skin, so that the doctor can quickly find the radial artery. In addition, the near-infrared light is transmitted through the sterile transparent developing film 4 and the near-infrared low-hydroxyl optical fiber 32, and the doctor's body position will not block the projection of the near-infrared light. In addition, the size is small and will not affect the doctor's subsequent operations.

[0059] Among them, the doctor places the auxiliary puncture mechanism 2 on the patient's radial artery with one hand, and keeps the auxiliary puncture mechanism 2 stable. The doctor's thumb and index finger are pinched at the hand contact block 29, and the other hand pinches the upper end of the puncture needle 1 to move the puncture needle 1 according to the imaging position of the radial artery. The puncture needle 1 will drive the limit block 23 to move at the same time during the movement. When the puncture needle 1 moves to the position of the radial artery and rotates a certain angle to prepare for puncture, the doctor's thumb and index finger pinch and press the hand contact block 29, and the hand contact block 29 will drive the pressure rod 28 to push the squeezing block 27. The squeezing block 27 will squeeze the elastic airbag 26 and contact the solid during the advancement process. The shaft column 24, which is pressed against with a certain force, is not easy to rotate, thereby limiting the angle of the puncture needle 1. After the internal gas of the squeezed elastic airbag 26 is transmitted to the cavity 222 inside the movable rod 22 through the through hole 241 on the shaft column 24, the rubber membrane 223 will expand. The expanded rubber membrane 223 will be clamped on both sides of the limit block 23, thereby limiting the puncture needle 1 passing through the limit block 23. When the position and angle of the puncture needle 1 are limited, when the personnel pinches the puncture needle 1 for puncture, even if the hand shakes, it will not cause the needle tip part of the puncture needle 1 to deviate, which greatly improves the success rate of radial artery puncture.

[0060] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
