Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a wound compression device. Background Art

[0002] Cardiac intervention is a minimally invasive interventional procedure that can be used for the diagnosis and treatment of coronary heart disease. Coronary angiography can be used to determine whether coronary heart disease exists. If the degree of coronary artery vascular disease is relatively serious, balloon angioplasty, stent implantation, coronary artery atherectomy or thromboembolism can be performed to treat coronary heart disease. For structural heart diseases, including valvular heart disease and congenital heart disease, interventional surgery can also be used, including balloon angioplasty, valve replacement surgery and occlusion surgery. It is necessary to choose the appropriate indications. Interventional treatment has the characteristics of less trauma and faster recovery, which reduces the trauma of patients and is conducive to the early recovery of the disease. Cardiac intervention is mainly between internal medicine and surgery and is an invasive treatment. For example, coronary artery intervention is mainly used to place artificial stents in the narrowed part of the coronary artery to help relieve the symptoms of stenosis. For example, valve intervention can help treat patients with severe stenosis of the aortic valve, especially elderly patients who cannot undergo open-chest and replacement surgery, so interventional treatment can be chosen.

[0003] Cardiac interventional therapy is a new technology for diagnosing and treating cardiovascular diseases. It does not require thoracotomy. Under the guidance of imaging methods, the catheter is sent to the lesion site through puncture of surface blood vessels with the help of certain instruments. The heart disease is diagnosed and treated through specific cardiac catheter operation techniques. The compression and hemostasis effect at the radial artery or femoral artery puncture site after surgery directly affects the patient's recovery speed after surgery. Usually, hemostasis methods include manual compression and mechanical compression. Since patients receive heparinization treatment during and after surgery, the compression time needs to be extended. Currently, manual compression or bandaging and pressurization are often used for treatment. The manual compression process is long and the workload is large. The bandaging and pressurization method is inconvenient to operate, and it is inconvenient to control the decompression operation during use, which brings inconvenience to the patient's treatment. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present utility model is to provide a wound compression device, which effectively solves the problem that it is inconvenient for medical staff to operate the wound pressure hemostasis after interventional surgery.

[0005] The technical solution is as follows: the utility model comprises a connecting block, a pressing rod is slidably connected inside the connecting block, the lower end of the pressing rod passes through the connecting block and is provided with a pressing block, an upper end of the connecting block is fixed with an up-and-down axial fixing plate, a through groove is coaxially opened in the middle of the fixing plate and opens downward, the upper end of the pressing rod is inserted into the through groove, a C-shaped piston cavity is opened on the fixing plate, the left side of the piston cavity is connected with the through groove via a connecting hole, an arc-shaped piston rod is slidably connected inside the piston cavity, a pushing block in the up-and-down directions is provided on the upper left end of the piston rod, fixing columns are respectively provided at the left and right ends of the connecting block, fixing belts are respectively mounted on the two fixing columns, an arc-shaped supporting pad is provided under the connecting block, positioning grooves are respectively opened on the left and right sides of the supporting pad, and the free end of the fixing belt passes through the positioning grooves on its corresponding sides.

[0006] The utility model has an ingenious structure and is easy to use. It is convenient for medical staff to press and stop bleeding on the puncture site of the patient after interventional treatment, and is also helpful for medical staff to control the pressing site. By moving the connecting block and the supporting pad, the pressing operation positioning is more flexible and convenient, which is convenient for medical staff to operate, and makes the initial positioning of the connecting block more stable. At the same time, only the push block needs to be turned to complete the compression of the patient's puncture site, and after maintaining it for a period of time, it is convenient for medical staff to perform timed decompression operations, which is beneficial to postoperative care of patients and convenient for medical staff to use.

[0017] In order to facilitate the movement of the block 18, the front end of the block 18 is connected to the rectangular groove 17 via a U-shaped elastic sheet 19, and the rear end face of the block 18 is an inclined surface tilted forward on the right side. A moving groove 20 with an opening facing upward and connected to the right end of the rectangular groove 17 is provided on the piston rod 8. A lever 21 fixedly connected to the block 18 is slidably connected in the moving groove 20, and the upper end of the lever 21 extends out of the moving groove 20.
