Description

Technical Field

[0001] The present invention relates to the field of angiography technology, and in particular to an intelligent pressing device for cardiovascular surgery angiography. Background Art

[0002] Cardiovascular surgery angiography is a procedure in which a catheter is inserted into the coronary artery of the heart through the patient's groin, arm or neck artery, and contrast agent is injected. X-ray imaging is then used to observe whether there is stenosis or blockage in the coronary artery. It is mainly used to evaluate the pathology of the coronary arteries, heart valves and other cardiovascular structures. When the catheter needs to be removed later, in order to prevent the catheter insertion site, i.e., the puncture site, from continuous bleeding, a pressing device is generally used to install gauze at the puncture site for about half an hour. This is to improve the postoperative hemostasis effect and reduce the burden on medical staff. This pressing device can be called a pressing device for cardiovascular surgical angiography.

[0003] However, the existing pressing device for cardiovascular surgery generally waits for the catheter to be pulled out before performing the hemostasis operation, and its timeliness of hemostasis is low. During the use of this device, it is possible that excessive bleeding may occur due to failure to perform the hemostasis operation in time. In addition, this pressing device for cardiovascular surgery cannot apply the corresponding amount of downward pressure according to the different patients. The comfort and intelligence of this device are low, and it is generally necessary to press the puncture site with this device for about half an hour before it can be removed. The hemostasis efficiency of the device is poor. Therefore, it does not meet the existing needs. We have proposed an intelligent pressing device for cardiovascular surgery. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. When it is necessary to remove the catheter on the patient's arm, the arm with the catheter inserted is placed on the arm placement table, and then the pressing head is pushed downward by the adaptive pushing mechanism until the gauze wrapped around the outer surface of the pressing head fits the puncture hole on the arm. When the two are just in contact, the adaptive pushing mechanism will immediately stop running, and then the tube removal operation will be directly performed. When the catheter inserted into the patient's body is completely removed, the adaptive pushing mechanism will immediately increase the downward pressure on the pressing head to prevent a large amount of blood from flowing out of the puncture hole. Through the above technical solution, the gauze is already in contact with the puncture hole before the catheter is removed, which can effectively reduce the risk of bleeding at the moment of tube removal. This pre-pressing method is more timely than the traditional pressing after tube removal and can better control bleeding. 2. Before using the device, the present invention requires medical staff to input data such as the patient's age, weight, puncture site, and condition on the input panel based on the patient's specific situation. Multiple preset modes, such as child mode, adult mode, and obese patient mode, can also be pre-stored on the input panel to facilitate medical staff to quickly select. Once the data input is completed or the preset mode is selected, the input panel will automatically adjust the pressing force based on this data, thereby achieving personalized, precise, and highly intelligent pressing operations, thereby providing patients with a safer and more comfortable experience. 3. The present invention uses pressure sensors, optical sensors, and ultrasonic sensors to monitor in real time the pressure applied to the puncture site and whether there is bleeding from the puncture site. The input panel will dynamically adjust the pressing force based on the real-time feedback data. For example, if the puncture site is still bleeding, the device will appropriately increase the pressing force. If the wound has closed, the device will gradually reduce the pressing force. As time goes by and the wound gradually heals, the device will gradually reduce the pressing force according to a preset time curve. This prevents the wound from bleeding again due to the sudden disappearance of the pressing force. The above technical solution improves the adaptability of the device. 4. The present invention can automatically spray alginate liquid on the outer surface of the gauze before performing the pressing operation through the accelerated healing mechanism. The alginate liquid sprayed on the outer surface of the gauze can accelerate the healing speed of the puncture hole on the patient's body, thereby reducing the pressing time. The above technical solution reduces the time required for a single pressing operation of this device and speeds up its overall operating efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] See also Figures 1 to 6 The present invention provides an embodiment of an intelligent pressing device for cardiovascular surgical angiography, comprising an arm resting platform 1, on the upper end surface of which is mounted a highly adaptable pressing device 2 for preventing extubation bleeding. The highly adaptable pressing device 2 for preventing extubation bleeding comprises a pressing head 211, a pressing head fixing base 204, and an adaptive pushing mechanism. An internal thread mounting groove 209 is provided in the middle of the lower end surface of the pressing head fixing base 204. A thread mounting head 210 matching the internal thread of the internal thread mounting groove 209 is provided inside the internal thread mounting groove 209, and the lower end surface of the thread mounting head 210 is fixed to the pressing head 211. A circular groove 213 is provided in the middle of the lower end surface of the pressing head 211. The interior of the circular groove 213 contains hemostatic gauze 214. The outside of the hemostatic gauze 214 is provided with gauze 215 that is wrapped around the outer surface of both the pressing head 211 and the hemostatic gauze 214. The adaptive pushing mechanism can move the pressing head 211 up and down, and when the gauze 215 wrapped around the outer surface of the pressing head 211 contacts the patient's arm, it can automatically apply different amounts of downward pressure according to the type of patient.

[0020] An accelerated healing mechanism is fixedly mounted on the outer surface of the pressing head fixed base 204. The accelerated healing mechanism includes a spray head mounting ring 15, a movable mechanism, and multiple alginate liquid spray heads 17. The multiple alginate liquid spray heads 17 are fixedly mounted in a ring shape on the lower side of the inner wall of the spray head mounting ring 15. The movable mechanism can move the spray head mounting ring 15 up and down or drive the spray head mounting ring 15 to rotate around the pressing head fixed base 204. The accelerated healing mechanism also includes two L-shaped mounting brackets 3, one side of the outer surface of the L-shaped mounting bracket 3 is fixedly mounted with an externally threaded mounting head 5, the outer surface of the externally threaded mounting head 5 is mounted with an alginate bottle 7 via a threaded structure, the interior of the alginate bottle 7 contains alginate liquid 8, and above the alginate liquid 8 is a small water pump 4 fixedly mounted inside the L-shaped mounting bracket 3, and one side of the outer surface of the small water pump 4 is connected to a pipette 6 inserted into the alginate liquid 8; The other side of the outer surface of the small water pump 4 is connected to an infusion tube 9. An annular metal shell 10 is provided between the two infusion tubes 9. An alginate liquid storage tank 18 is provided inside the annular metal shell 10, and the two infusion tubes 9 are simultaneously connected to the interior of one alginate liquid storage tank 18; the lower end inner wall of the alginate liquid storage tank 18 is provided with an annular through hole 21 that penetrates the annular metal shell 10 and extends to the outside of the annular metal shell 10. The interior of the annular through hole 21 contains a sealing ring 20 fixed between its lower end surface and the spray head mounting ring 15. The outer surface of the sealing ring 20 is in contact with the inner wall of the annular through hole 21, and the sealing ring 20 and the annular through hole 21 are slidably connected; A plurality of L-shaped liquid extraction tubes 16 are fixedly installed inside the sealing ring 20. The number and position of the L-shaped liquid extraction tubes 16 correspond to the position and number of the alginate liquid spray heads 17. The bottom ends of the L-shaped liquid extraction tubes 16 are connected to the corresponding alginate liquid spray heads 17, and the alginate liquid spray heads 17 are connected to the interior of the alginate liquid storage tank 18 through the L-shaped liquid extraction tubes 16; the anti-extubation bleeding type highly adaptable pressing device 2 also includes an input panel 203, and the adaptive pushing mechanism and the accelerated healing mechanism are electrically connected to the input panel 203; the adaptive pushing mechanism and the accelerated healing mechanism can be controlled by the input panel 203. Before using the device, the alginate liquid 8 located inside the alginate bottle 7 is first extracted by a small water pump 4 and a pipette 6 and transported to the interior of the alginate liquid storage tank 18 located inside the annular metal shell 10 through the infusion tube 9 until the interior of the alginate liquid storage tank 18 is filled with alginate liquid 8.

[0021] The movable mechanism includes two pushing cylinders 19, and the piston rods of the two pushing cylinders 19 are fixedly connected to the two sides of the upper end surface of the spray head mounting ring 15; before the pressing operation, the pushing cylinder 19 is started to push the spray head mounting ring 15 connected thereto downward. As the spray head mounting ring 15 descends, a circle of alginate liquid spray heads 17 installed on its inner wall will move downward together. When the alginate liquid spray head 17 moves to the same horizontal line as the pressing head 211, the alginate liquid spray head 17 will extract the alginate liquid in the alginate liquid through the L-shaped liquid extraction pipe 16 connected thereto. The alginate liquid 8 in the storage tank 18 is sprayed toward the pressing head 211. The alginate liquid 8 sprayed toward the pressing head 211 will be absorbed by the gauze 215 wrapped around the outer surface of the pressing head 211 and the hemostatic gauze 214 located in the circular groove 213 at the lower end surface of the pressing head 211. By spraying the alginate liquid 8 on the outer surface of the gauze 215 before the pressing operation, the healing speed of the puncture wound on the patient's body is accelerated, thereby reducing the pressing time. The above technical solution reduces the time required for a single pressing operation of the device and improves its overall operating efficiency. From the left to the right, the first push cylinder 19 is provided with a rotating motor 11 fixedly mounted inside the annular metal shell 10. The output shaft of the rotating motor 11 is connected to the transmission shaft 12 through a coupling. The outer surface of the transmission shaft 12 is fixed with a gear column 13. One side of the outer surface of the gear column 13 is meshed with a gear 14 fixed to the inner wall of the spray head mounting ring 15. When the alginate liquid spray head 17 starts to spray, the rotating motor 11 is started, and the rotating motor 11 can drive the transmission shaft 12 and the fixed sleeve connected thereto. The gear column 13 provided on the outer surface of the transmission shaft 12 rotates, and the rotating gear column 13 can drive the gear 14 meshing therewith and the spray head mounting ring 15 fixed to the outer side of the gear 14 to rotate together. When the spray head mounting ring 15 rotates, a circle of alginate liquid spray heads 17 fixed on the inner wall of the spray head mounting ring 15 will rotate along with it. By rotating the alginate liquid spray heads 17, the spraying range of the alginate liquid spray heads 17 can be increased, thereby ensuring that as many locations as possible on the outer surface of the gauze 215 can absorb the alginate liquid 8; When the spraying operation is completed, the spray head mounting ring 15 and the alginate liquid spray head 17 are pulled back to their original positions by the pushing cylinder 19. By pulling the spray head mounting ring 15 and the alginate liquid spray head 17 back to their original positions, the lower end surface of the downwardly moving spray head mounting ring 15 is prevented from contacting the patient's arm, thereby preventing the patient's arm from being compressed. As the spray head mounting ring 15 moves downward, the sealing ring 20 fixed on its upper end surface will move downward therewith. The sealing ring 20 can seal the annular through hole 21 located on the inner wall of the lower end of the alginate liquid storage tank 18 to prevent the alginate liquid 8 located inside the alginate liquid storage tank 18 from leaking. The sealing ring 20 and the annular through hole 21 can prevent the L-shaped liquid extraction tube 16 inserted into the alginate liquid storage tank 18 from being stuck, thereby preventing the tube from rotating or moving up and down.

[0022] The adaptive pushing mechanism includes a metal shell 201, a pressing cylinder 202 is fixedly installed in the middle position of the upper end surface of the metal shell 201, the piston rod of the pressing cylinder 202 is connected to a strip plate 212, and an adaptive connecting rod 205 is fixedly connected to the middle position of the lower end surface of the strip plate 212. A metal ring 206 is fixedly sleeved on the lower side of the outer surface of the adaptive connecting rod 205; the outer side of the metal ring 206 is provided with a cylindrical groove 207 inside the pressing head fixed base 204, and the cylindrical groove 207 contains a spring 208 inside. The upper and lower ends of the spring 208 are connected to the lower end surface of the metal ring 206 and the lower end inner wall of the cylindrical groove 207 respectively; when it is necessary to pull out the catheter on the patient's arm, the arm with the catheter inserted is placed on the arm placement table 1, and then the pressing cylinder 202 is used to push downward the pressing head fixed base 204 connected to it through the strip plate 212 and the appropriate connecting rod 205. As the pressing head fixed base 204 descends, the distance between the pressing head 211 installed on the lower end surface of the pressing head fixed base 204 and the puncture port is reduced. It will gradually shrink. When the gauze 215 wrapped around the outer surface of the pressing head 211 fits the puncture hole on the arm and the metal ring 206 fixed on the lower side of the outer surface of the appropriate connecting rod 205 has not been squeezed, the pressing cylinder 202 will stop running immediately, and then the tube removal operation will be carried out directly. When the catheter inserted into the patient's body is completely pulled out, the pressing cylinder 202 will immediately push the strip plate 212 downward. As the strip plate 212 descends, the appropriate connecting rod 205 fixed on the lower end surface of the strip plate 212 will be pushed down. The metal ring 206 fixedly mounted on the outer surface of the suitability connecting rod 205 will move downward therewith and squeeze the spring 208 connected to the lower end surface of the metal ring 206, thereby increasing the downward pressure applied to the puncture site to prevent a large amount of blood from flowing out of the puncture site. Through the above technical solution, the gauze 215 is already in contact with the puncture site before the catheter is removed, which can effectively reduce the risk of bleeding at the moment of removal. This pre-pressing method is more timely than the traditional pressing method after removal of the catheter and can better control bleeding. In the above technical solution, the downward force applied to the puncture site is increased by squeezing the spring 208. Compared with the downward force applied by directly pushing the cylinder downward, this method has higher safety, flexibility and reliability. In addition, the spring 208 has a certain elastic buffering effect. During the pressing process, if the pressing force is too large, the spring 208 can automatically adjust to avoid excessive pressure on the puncture site, reducing the risk of tissue damage. The spring 208 can flexibly adjust the pressing force according to actual needs. By changing the compression degree of the spring 208, the pressing force can be gradually increased or decreased to meet the needs of different patients. Before using the device, medical staff need to input the patient's age, weight, puncture site, condition and other data on the input panel 203 according to the patient's specific situation. A variety of preset modes can also be pre-stored on the input panel 203, such as child mode, adult mode, obese patient mode, etc., to facilitate medical staff to quickly select. When the data input is completed or the preset mode is selected, the input panel 203 will automatically adjust the pressing force according to these data, thereby realizing personalized, precise and highly intelligent pressing operations, thereby providing patients with a safer and more comfortable experience.

[0023] A pressure sensor 216 is fixedly mounted in the middle of the inner wall of the upper end of the circular groove 213, and the pressure sensor 216 is electrically connected to the input panel 203. An optical sensor 218 is fixedly mounted on one side of the lower end surface of the metal housing 201. An ultrasonic sensor 219 is located behind the optical sensor 218 and is also fixedly mounted on the lower end surface of the metal housing 201. Both the optical sensor 218 and the ultrasonic sensor 219 are electrically connected to the input panel 203. The pressure applied to the puncture site and the presence of bleeding at the puncture site can be monitored in real time by the pressure sensor 216, the optical sensor 218, and the ultrasonic sensor 219. The input panel 203 dynamically adjusts the pressing force based on the real-time feedback data. For example, if bleeding is detected at the puncture site, the device will appropriately increase the pressing force. If the wound has closed, the device will gradually reduce the pressing force. As time passes and the wound gradually heals, the device will gradually reduce the pressing force according to a preset time curve to prevent the wound from bleeding again due to a sudden loss of pressing force. The above technical solution improves the adaptability of the device. Furthermore, the operation of the pressing cylinder 202 can be more accurately controlled by monitoring the pressure sensor 216, the optical sensor 218, and the ultrasonic sensor 219, thereby preventing the situation where the gauze 215 just contacts the puncture hole but the pressing cylinder 202 continues to push the strip plate 212 downward. When the pressing operation needs to be ended, the pressing head fixing base 204 is pulled upwards. When the gauze 215 is no longer in contact with the puncture port, the arm placed on the arm placement table 1 can be pulled out. Then, before performing the next pressing operation, the pressing head 211 is removed through the spring 208 on the lower end surface of the pressing head fixing base 204 and the threaded mounting head 210 fixed to the upper end surface of the pressing head 211, and the hemostatic gauze 214 inside the circular groove 213 on the lower end surface of the pressing head 211 and the gauze 215 wrapped around the outer surface of the pressing head 211 are replaced. After the hemostatic gauze 214 and the gauze 215 are replaced, the pressing head 211 can be reinstalled through the internal thread mounting groove 209 and the threaded mounting head 210.

[0024] A guide rod 217 fixed to the lower end surface of the strip plate 212 is provided on the front and rear sides of the suitability connecting rod 205, and the bottom end of the guide rod 217 is movably inserted into the interior of the pressing head fixed base 204; by fixing the guide rod 217 on the lower end surface of the strip plate 212 and inserting into the interior of the pressing head fixed base 204, the overall stability of the pressing head fixed base 204 can be ensured to prevent it from tilting.

[0025] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
