Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to a dynamic convergent discrete pressure hemostasis device for cardiovascular surgery. Background Technology

[0002] The incidence of coronary heart disease remains high, posing a serious threat to patients' health due to serious problems such as coronary artery stenosis caused by atherosclerosis and myocardial ischemia. Traditional methods such as electrocardiograms and exercise stress tests are insufficient to accurately identify details of coronary artery lesions. While coronary CT angiography (CCTA) is non-invasive, it has errors in stenosis assessment and cannot provide simultaneous treatment. Therefore, coronary angiography (CAG), as the "gold standard" of minimally invasive intervention, has emerged. It delivers contrast agent through peripheral vessels, using X-rays to dynamically visualize coronary artery morphology, accurately assessing lesions. It is widely used in the diagnosis of coronary heart disease and emergency assessment, providing crucial information for treatment. Especially in emergencies, it can quickly locate blocked blood vessels, facilitating timely treatment and improving prognosis.

[0003] Coronary angiography, specifically, involves using an angiography machine to insert a specific catheter into the femoral artery of the lower limb, retrogradely along the descending aorta to the root of the ascending aorta, and then probing the left or right coronary artery orifice to insert and inject contrast agent, thus visualizing the coronary artery. Because the catheter diameter is relatively large, a large needle hole is left on the femoral artery wall at the puncture point. After the procedure, effective pressure needs to be applied to this point. Currently, the main methods used are single-point pressure with air, or applying gauze with weights, or prolonged manual pressure. These methods not only affect the hemostasis effect but also easily cause wound infection, and still have certain shortcomings.

[0004] Therefore, a dynamic convergent discrete pressure hemostasis device for cardiovascular surgery is needed to solve the above-mentioned technical problems. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention presents a dynamic convergent discrete pressure hemostasis device for cardiovascular surgery. This device is capable of performing discrete pressure and allows for adjustment of the discrete pressure points as needed. Furthermore, the device can simultaneously time the pressure points and record the time for effective reminders.

Detailed Implementation

[0024] Example 1

[0025] A dynamic convergent discrete pressure hemostasis device for cardiovascular surgery includes: an adjustment device and a pressure head 3. The pressure head 3 is fixedly installed at the lower end of the adjustment device, and several fixing straps 23 are also fixedly installed circumferentially on the outer side of the adjustment device. The pressure head 3 includes: a support column 31, a spring 33, an outer shell 32, and a raised ring 36. The outer shell 32 is fixedly installed at the lower end of the support column 31, and the spring 33 is also fixedly installed inside the support column 31. The outer shell 32 is made of a soft elastic material, and the raised ring 36 is also fixedly installed at the lower end of the outer shell 32. The discretely installed pressure head 3 effectively applies pressure to the puncture point.

[0026] This device constructs a dynamic convergent adjustment structure through a designed adjustment mechanism (including a rotating disk 1, a fixed disk 2, and a movable plate 26). The second groove 27 of the circumferential array of the fixed disk 2 corresponds to and engages with the first groove 261 of the movable plate 26. The limiting rod 221 at the lower end of the rotating disk 1 passes through the two grooves. Rotating the handle 11 drives the movable plate 26 to move along the groove, thereby driving the pressing head 3 to achieve discrete position adjustment. Through the above design, it can effectively solve the single mode of traditional single-point pressing, gauze with weight, or manual pressing. It can achieve point-like pressing of the puncture point through discrete adjustment, accurately acting on the core bleeding area, and can achieve block pressing by adjusting the concentration of the pressing head 3, adapting to the differences in femoral artery puncture point size, vessel diameter, and hemostasis needs of different patients, avoiding the problems of incomplete hemostasis or excessive compression of surrounding tissues caused by improper coverage of traditional pressing.

[0027] In this embodiment, a contact head 35 is fixedly installed at the lower end of the spring 33. The contact head consists of a support plate 351 and a contact piece 352 that are bonded together. A raised ring 36 is also provided on the raised ring 36, and the contact pieces 352 between the two contact heads 35 are installed opposite each other. A wire 34 is also fixedly installed on the contact head 35. The wire 34 extends upward into the adjusting device inside the spring 33. The contact piece 352 is a metal conductive sheet. The metal conductive sheet is mainly made of copper, which is inexpensive and has good conductivity. Specifically, there are two wires 34, and the main function of the contact piece 352 is to connect, equivalent to the connection relationship of a circuit.

[0028] Specifically, the compression head 3 adopts a composite structure of "support column 31 + spring 33 + soft elastic outer shell 32". The spring 33 provides a continuous and controllable elastic compression force, which can ensure that sufficient pressure is applied to the puncture point to stop bleeding, and can also avoid vascular damage caused by rigid compression through the buffering effect of the spring 33. The soft elastic outer shell 32 fits the skin surface, and together with the raised ring 36 at the lower end, it enhances the compression seal and reduces the risk of blood leakage. At the same time, several fixing straps 23 on the outer circumferentially fixed side of the device can directly and firmly fix the device to the patient's femoral artery, replacing the traditional manual long-term compression or heavy object compression, avoiding compression position displacement caused by loose fixation, and eliminating the need for continuous medical staff to be on duty, reducing labor costs, and reducing the risk of wound contamination caused by manual operation, solving the problem that traditional compression is prone to hemostasis failure or infection due to unreliable fixation. The contact head 35 of the pressing head 3 is connected to the control module 24 of the adjustment device via the wire 34. When the contact head 35 is pressed against the puncture point, the conductive sheet triggers the control module 24 to start the timing function. The loudspeaker 25 on one side of the control module 24 can issue a reminder when the preset hemostasis time (such as the conventional hemostasis time for femoral artery puncture) is reached, so as to avoid medical staff missing the timing due to being busy, resulting in insufficient or excessive pressing time. Insufficient pressing time can easily cause secondary bleeding, while excessive pressing time may lead to local tissue ischemic necrosis.

[0029] Example 2

[0030] Specifically, in this embodiment, based on the adjustment device described in Embodiment 1, the adjustment device includes a rotating disk 1, a fixed disk 2, and a movable plate 26; the fixed disk 2 has a plurality of second sliding grooves 27 arranged in a circular array inside, and the movable plate 26 is movably installed on the fixed disk 2, and the movable plate 26 also has a first sliding groove 261 arranged on the movable plate 26, with the first sliding groove 261 and the second sliding groove 27 installed correspondingly; a limit rod 221 is fixedly installed in a circular array at the lower end of the rotating disk 1, and the limit rod 221 is installed between the first sliding groove 261 and the second sliding groove 27; a control module 24 is also fixedly arranged on the outside of the fixed disk 2, and a loudspeaker 25 is fixedly installed on one side of the module.

[0031] Meanwhile, an extension ring 21 is fixedly installed on the outer side of the rotating disk 1, and a plurality of limiting holes 22 are provided on the extension ring 21; at the same time, a handle 11 is fixedly installed at the upper center of the rotating disk 1, and a fixing rod 12 is fixedly installed on one side of the handle 11. The fixing rod 12 is elastic and its other end extends to the upper end of the limiting hole 22; the specific process is that when the rotating disk 1 is rotated, under the drive of the limiting rod 221 of the rotating disk 1, the limiting rod 221 will slide in the first slide groove 261 and the second slide groove 27. By sliding, the movable plate 26 is brought together or dispersed, thereby driving the pressing head 3 to perform discrete adjustment.

[0032] The usage process of this invention is as follows: After coronary angiography, the device is placed directly above the puncture point. First, adjust the position of the pressing head 3 using the adjustment device. Hold the handle 11 at the upper end of the rotating disk 1 and rotate it clockwise. The limiting rod 221 slides along the second sliding groove 27 of the fixed disk 2 and the first sliding groove 261 of the movable plate 26, causing the movable plate 26 to converge towards the center synchronously, so that the pressing head 3 gathers around the puncture point, forming a ring-shaped discrete pressing layout around the puncture point. If the bleeding area of ​​the puncture point is slightly large, the handle 11 can be rotated counterclockwise, so that the movable plate 26 drives the pressing head 3 to spread outward, expanding the pressing coverage area. After adjusting until the pressing head 3 completely covers the bleeding area, press the elastic fixing rod 12 on one side of the handle 11 of the rotating disk 1, so that it is inserted into the limiting hole 22 corresponding to the extension ring 21, locking the position of the pressing head 3.

[0033] Next, the fixing straps 23 on the outside of the adjustment device are wrapped around the patient's groin, and the tightness is adjusted with Velcro to ensure that the device is securely fixed and does not affect the patient's lower limb blood circulation. At this time, the contact piece 352 of the pressing head 3 is in contact with the skin of the puncture point, and the metal conductive piece triggers the control module 24 to start the timing function. The display screen of the control module 24 shows the pressing time in real time. During the pressing process, the spring 33 continuously provides elastic pressure, and the soft elastic outer shell 32 and the raised ring 36 are tightly in contact with the skin to prevent blood from leaking from the pressing edge. When the pressing time reaches the preset femoral artery puncture hemostasis time (e.g., 20 minutes), the loudspeaker 25 on one side of the control module 24 emits a "beep beep" reminder sound. Medical staff can first press the pause button of the control module 24 to turn off the reminder, and then slowly loosen the fixing straps 23. After removing the device, observe the hemostasis of the puncture point. If there is no bleeding, routine dressing can be applied. If there is still a small amount of bleeding, the position of the pressing head 3 can be readjusted (repeat the above adjustment steps of rotating handle 11), and the device can be fixed again for short-term supplementary pressing.
