Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a pressing hemostasis device for cardiology department. Background Art

[0002] The cardiology department, that is, the cardiovascular medicine department, 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 and other cardiovascular diseases. When performing a radial artery puncture in the cardiology department, hemostasis needs to be performed on the puncture site. For example, a pressing hemostasis device for the cardiology department proposed in the patent publication number CN115530912A.

[0003] When the existing pressing hemostasis device is in use, the medical staff usually manually adjusts the pressing force of the hemostasis device to press and stop bleeding at the puncture point. Due to the different subcutaneous fat contents of different patients, obese patients have a thick subcutaneous fat layer, and the hemostasis device needs to apply a greater pressure to make the blood vessels at the pressing site be sufficiently compressed, so that the blood vessels are closed to achieve the purpose of hemostasis. If the pressing force is too small, the blood vessels cannot be effectively compressed, which is likely to cause continuous bleeding and form a subcutaneous hematoma. While thin patients have less subcutaneous fat and the blood vessels are closer to the body surface, the hemostasis device can compress the blood vessels by applying a smaller pressure. If the pressing force is too large, due to the pressure concentrating on the blood vessels, it is easy to block the local blood circulation, resulting in tissue ischemia, hypoxia, causing discomfort symptoms such as pain and numbness, and may even damage the blood vessels and surrounding tissues.

[0004] Therefore, a pressing hemostasis device for the cardiology department is proposed to solve the above problems. Summary of the Invention

While ensuring that the blood vessel is sufficiently compressed and closed, it also avoids excessive pressure on the blood vessel, resulting in tissue ischemia, hypoxia, and causing discomfort symptoms such as pain and numbness.

[0037] The hanging component 28 includes a rotating handle 281 arranged on the upper side of the installation box 1. Above the rotating handle 281, there is a hanging frame 282. A hanging ring 29 is fixedly connected to the upper side wall of the hanging frame 282. A rope wheel 30 is rotatably connected to the inner wall of the hanging frame 282. A self - locking motor 31 is fixedly connected to the right side wall of the hanging frame 282. The output end of the self - locking motor 31 passes through the hanging frame 282 and is fixedly connected to the rope wheel 30. A pull rope 32 is wound around the rope wheel 30. A rope hole is formed in the lower side wall of the hanging frame 282. The lower end of the pull rope 32 passes through the rope hole and is connected to the upper side wall of the rotating handle 281 through a rope loop. An induction component 34 is connected to the right side wall of the installation box 1. The induction component 34 is electrically connected to the self - locking motor 31 through the PLC controller 2. When the patient has upper limb venous return disorder, after using the pressure - applying hemostasis device to apply pressure to the puncture point for hemostasis, the patient's arm can be automatically lifted upward by a certain angle, which can promote venous blood return, reduce local venous pressure, and is beneficial to hemostasis and prevention of local congestion.

[0038] The induction component 34 includes an induction cylinder 341 fixedly connected to the right side of the installation box 1. The induction cylinder 341 is of a cylindrical structure. A rotating column 342 is rotatably connected to the left inner wall of the induction cylinder 341. A vertical rod 35 is fixedly connected to the lower side wall of the rotating column 342. A square block 36 is fixedly connected to the lower end of the vertical rod 35. A conductive head 37 is fixedly connected to the left side wall of the square block 36. The conductive head 37 is electrically connected to the micro power supply 3. A conduction piece 38 is embedded in the left inner wall of the induction cylinder 341. The conduction piece 38 is of an arc - shaped structure. The conduction piece 38 is electrically connected to the PLC controller 2 and can sense the placement angle of the patient's arm.

[0039] A limiting plate 39 is fixedly connected to the inner wall of the installation box 1. A limiting groove 40 that matches the limiting plate 39 is formed in the rod wall of the self-locking threaded rod 5. Through the mutual cooperation of the limiting plate 39 and the limiting groove 40, the rotation of the self-locking threaded rod 5 is avoided, so that the self-locking threaded rod 5 can only move up and down in the vertical direction.

[0040] A rotating plate 41 is fixedly connected to the upper end of the internal thread cylinder 4. The surface of the rotating plate 41 is provided with friction lines 33 to facilitate the rotation of the internal thread cylinder 4.

[0041] The operating principle of the present invention is described as follows: The medical staff aligns the pressing component 7 with the puncture point on the patient's arm, then adheres the hemostatic cotton 9 to the puncture point and presses it. Then, the strap 20 is wound around the patient's arm, and the lower end of the strap 20 is passed through the fixing frame 21 and pulled downward tightly. After the pulling force sensor 192 detects that the pulling force of the strap 20 reaches the set threshold (about 1 N), the pulling force sensor 192 will control the buzzer 27 to emit a "beep" prompt sound through the PLC controller 2. After hearing this prompt sound, the medical staff can rotate the end of the strap 20 and fix the strap 20 on the fixing frame 21 through the magic tape structure 22. When the strap 20 is passed through the fixing frame 21, the conductive column 23 arranged inside the fixing frame 21 will pass through the rubber stoppers 26 on both sides of the analysis groove 24 and contact the flexible resistance strip 25. When the subcutaneous fat of the patient's arm is relatively thick, the pulling force sensor 192 will detect that the pulling force of the strap 20 reaches the set threshold when the strap 20 passes through a relatively short distance of the fixing frame 21, and the conductive column 23 will contact the position of the flexible resistance strip 25 close to the lower end. One end of the flexible resistance strip 25 close to the connecting block 191 is electrically connected to the PLC controller 2 (equivalent to the upper end of the flexible resistance strip 25 being electrically connected to the PLC controller 2), and the conductive column 23 is electrically connected to the micro power supply 3. Since the length of the flexible resistance strip 25 connected to the circuit becomes longer, the resistance of the circuit connected to the PLC controller 2 is larger. Under the condition that the voltage of the micro power supply 3 remains unchanged, the current signal transmitted to the circuit of the PLC controller 2 is smaller, indicating that the patient's subcutaneous fat is thicker, and the hemostatic device needs to apply a greater pressure to make the blood vessels at the pressing part be sufficiently compressed (the required pressure is about 30 - 50 mmHg). The medical staff needs to manually rotate the rotating plate 41, and the rotating plate 41 drives the internal thread cylinder 4 to rotate (the adjusting motor 18 is a non-brake motor. When the rotating plate 41 drives the internal thread cylinder 4 to rotate, the bevel gear transmission component between the internal thread cylinder 4 and the adjusting motor 18 will not cause the internal thread cylinder 4 to lock). The self-locking threaded rod 5 is driven to move downward through thread cooperation. The self-locking threaded rod 5 presses the pressing plate 71 downward through the pressure sensor 6, and the pressing plate 71 drives the hemostatic cotton 9 to press the blood vessel puncture point. When the pressure sensor 6 detects that the pressure between the pressing plate 71 and the patient's arm reaches 30 - 50 mmHg, the pressure sensor 6 will control the buzzer 27 to emit a "beep beep" prompt sound through the PLC controller 2 to remind the medical staff that the pressing intensity reaches the set standard, and the medical staff can stop rotating the rotating plate 41. Similarly, by repeating the above operations, the pressing hemostatic device can be installed for patients with less subcutaneous fat;

[0042] When there is upper limb venous return disorder in a patient (such as venous valve insufficiency, etc.), it is necessary to lift the patient's arm at a certain angle to promote venous blood return, reduce local venous pressure, which is beneficial for hemostasis and preventing local congestion. After installing the hemostasis device on the patient's arm, and when the hemostasis device is installed on the patient's arm, in order to avoid the arm drooping, under the action of gravity, it will increase the blood return resistance at the puncture site and raise the local intravascular pressure, leading to the problem of increased bleeding at the puncture point. The doctor needs to lift the patient's arm to avoid the arm drooping. Then the medical staff needs to take out the hanging frame 282 placed aside, and turn the rotary handle 281 upward. Then connect the pull rope 32 inside the hanging frame 282 with the rope loop on the upper side of the rotary handle 281. Then hang the hanging ring 29 on the upper side of the hanging frame 282 on the infusion stand above the hospital bed. Then the medical staff sends an electrical signal to the PLC controller 2 through a remote control device (or a control button with a connecting wire). After receiving this electrical signal, the PLC controller 2 will control the self-locking motor 31 to work. The self-locking motor 31 will drive the rope wheel 30 to rotate, and use the rope wheel 30 to wind up the pull rope 32. The pull rope 32 will drive the hemostasis device and the patient's arm to move upward. When the hemostasis device and the patient's arm move upward, the arm will rotate upward with the shoulder as the origin. And the mounting box 1 is installed on the arm at this time. The mounting box 1 will rotate upward with the arm with the shoulder as the origin. The mounting box 1 will drive the induction cylinder 341 to rotate together. The induction cylinder 341 will drive the internal conduction piece 38 to rotate together (refer to Figure 7 as shown). Under the action of gravity, the square 36 and the conductive head 37 will maintain a vertical state. When the patient's arm rotates 30 - 45°, the conductive head 37 will contact the conduction piece 38. The conductive head 37 is electrically connected to the micro power supply 3, and the conduction piece 38 is electrically connected to the PLC controller 2. When the conductive head 37 contacts the conduction piece 38, it will send an electrical signal to the PLC controller 2. After receiving this electrical signal, the PLC controller 2 will control the self-locking motor 31 to stop working, so that the patient's arm is lifted at a certain angle and maintained, promoting venous blood return, reducing local venous pressure, which is beneficial for hemostasis and preventing local congestion;

[0043] When the timing module inside the PLC controller 2 detects that the hemostatic device has been working for six hours, the PLC controller 2 will control the regulating motor 18 to work slowly. The regulating motor 18 will drive the internal thread cylinder 4 to rotate in the reverse direction (the regulating motor 18 is a non-brake motor), thereby controlling the pressing member 7 to move upward by a small distance and reducing the pressure of the hemostatic device on the puncture point. (Normally, after working for six hours, the hemostatic device can gradually reduce the pressure within the subsequent two to five hours and be removed.) When the hemostatic device reduces the pressure for the first time, but there is still a small amount of bleeding at the patient's puncture point, a small amount of blood will spread to the extension part 17 through the hemostatic cotton 9, turning the extension part 17 red (when there is a small amount of blood in the extension part 17 originally, the color will deepen after bleeding occurs). After detecting this situation through the optical sensor 151, the optical sensor 151 will control the regulating motor 18 to work in the reverse direction through the PLC controller 2, controlling the pressing part to squeeze and press the puncture point. At the same time, the PLC controller 2 will also control the micro pump 11 to work (when the hemostatic device is first used, the PLC controller 2 will also control the micro pump 11 to work intermittently for half an hour). The micro pump 11 will transport medicaments such as thrombin stored in the installation box 1 to the annular cavity 72 (the side wall of the installation box 1 is provided with an adding pipe, and medicaments such as thrombin can be added to the installation box 1 through the adding pipe), and transport them to the hemostatic cotton 9 and penetrate to the puncture point through the liquid leakage hole 8, further promoting the healing of the blood vessel.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
