Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to an open compression device. Background Technology

[0002] Interventional treatment is an emerging treatment method that lies between surgery and internal medicine, encompassing both endovascular and non-vascular interventional therapies. After more than 30 years of development, it has now become one of the three pillar disciplines alongside surgery and internal medicine. Simply put, interventional treatment involves creating tiny channels (a few millimeters in diameter) in blood vessels or skin, or through existing bodily channels, to treat the lesion locally under the guidance of imaging equipment (angiography, fluoroscopy, CT, MRI, ultrasound). Typically, interventional diagnostic and therapeutic procedures, especially in neurosurgery, are performed via the femoral artery. Femoral artery access offers advantages such as high success rates and low surgical difficulty; however, due to the relatively large size and high blood pressure of the femoral artery, achieving complete hemostasis post-procedure is challenging. After the interventional procedure is completed and the catheter is removed, the doctor or medical professional applies pressure to the puncture site of the arterial catheter to achieve hemostasis and closure of the arterial puncture site. Hemostasis and closure of the arterial puncture site require continuous and stable pressure. Generally, the pressure is higher at the beginning and needs to be gradually reduced after a period of time to ensure that the downstream tissues of the blood vessel receive a rich blood supply.

[0003] Existing compression hemostatic devices, once pressurized, are difficult to remove when the catheter sheath needs to be pulled out, and the compression point is easily displaced during the removal process due to the obstruction of the device's support. For example, invention patent (CN104490443B) discloses a femoral artery compression hemostatic device. The device includes at least a hemostasis unit and a fixation unit. The hemostasis unit includes a pressure knob, a pressure column fitted onto and threadedly connected to the pressure knob, and a pressure pad movably connected to the bottom surface of the pressure knob. The fixation unit is connected to the pressure column. The fixation unit includes a support stabilizing rod, a tail fin fixed to the support stabilizing rod, a leg support plate located below the support stabilizing rod, and a fixing strap. The support stabilizing rod is connected to the leg support plate via the fixing strap. The support stabilizing rod is perpendicular to the pressure knob, with one end connected to the tail fin and the other end threadedly connected to the pressure column. The pressure pad includes a base pad, a vascular pressure pad, and a hemostatic dressing. Both the base pad and the vascular pressure pad are silicone pads. The hemostatic dressing is a freeze-dried sponge containing hemostatic drugs. The vascular pressure pad and the hemostatic dressing are fixed to the bottom surface of the base pad, one on the left and one on the right. The vascular pressure pad is close to the hemostatic dressing, the area of ​​the hemostatic dressing is larger than the area of ​​the vascular pressure pad, and the height of the vascular pressure pad is not less than the height of the hemostatic dressing.

[0004] The aforementioned compression hemostat can only compress the bleeding point after applying pressure. However, during the removal process, the catheter sheath is inconvenient to remove due to the obstruction of the support part, and it can only be removed from the side. The compression point is prone to displacement during the removal process. Utility Model Content

[0028] Reference Figure 1 , Figure 2 This embodiment discloses an open-type compression device, including a compression device. The compression device body includes a hemostatic part 1, a support part 2 connected to the hemostatic part 1, and a fixing part 3 connected to the support part 2. The support part 2 is provided with an opening for observing the hemostasis status, and an opening and closing device 21 is provided in the opening. After the patient undergoes interventional surgery (interventional surgery is usually performed through the patient's femoral artery access, so this embodiment takes femoral artery interventional surgery as an example), the hemostatic part 1 is used to compress and stop the bleeding at the bleeding point. The hemostatic part 1 includes a pressure knob 212, a pressure column sleeved on the pressure knob 212 and threadedly connected to the pressure knob 212, and a pressure pad movably connected to the bottom surface of the pressure knob 212. The support part 2 is connected to the pressure column. An air balloon located inside the pressure column is connected to the pressure knob 212. In use, first place a clean, sterile gauze pad on the area requiring compression to stop the bleeding, then place a compression pad on top of the gauze. Next, secure the fixing part 3 to the patient's leg. The fixing part 3 is made of a flexible, elastic material, and its two ends are connected by detachable methods such as zippers, buttons, or straps. In this embodiment, Velcro is used. The fixing part 3 consists of two flexible elastic bands, each with a rough surface and a hook surface at its end. After wrapping the elastic band around the patient's leg, secure the compressor with Velcro. Once secured, rotate the pressure knob 212 downwards to further and more precisely compress the bleeding point. The support part 2 ensures more accurate pressure on the affected area, preventing other areas from being compressed. When it is necessary to remove the catheter sheath, the opening and closing device 21 can be opened.

[0029] like Figure 2As shown, the opening and closing device 21 includes a movable cover 211 movably disposed on the support part 2, a fixed post 213 disposed on the support part 2, a pull rope 214 passing through the movable cover 211 and having one end sleeved with the fixed post 213, and a knob 212 with the other end of the pull rope 214 wound around it. The knob 212 controls the opening and closing of the movable cover 211 through the pull rope 214. (Refer to...) Figure 3 , Figure 4 To more easily keep the opening and closing part closed and increase the supporting force of the support part 2, a locking device is provided on the knob 212. The locking device includes a locking boss 2121 at the contact end between the knob 212 and the support part 2, and a limiting groove 217 at the corresponding position of the support part 2 and the locking boss 2121. The locking boss 2121 and the limiting groove 217 are engaged. To further enable the locking boss 2121 of the knob 212 to be provided with a friction surface 2122, when the locking boss 2121 is engaged into the limiting groove 217, the friction surface 2122 will generate a certain resistance. It is necessary to align the locking boss 2121 of the knob 212 with the limiting groove 217 and press it down to make the locking boss 2121 engage into the limiting groove 217.

[0030] After the locking boss 2121 engages with the limiting groove 217, a spring 216 is fixedly installed between the movable cover 211 and the support part 2 to facilitate easier opening of the opening and closing part. The spring 216 can drive the opening and closing cover to reset. After the locking boss 2121 of the knob 212 is pulled out of the limiting groove 217, the pull rope 214 is loosened, and the movable cover 211 is elastically driven to both sides by the springs 216 on both sides, realizing the opening and closing device 21. Guide grooves 215 for limiting the springs 216 are provided between the two sides of the movable cover 211 and the support part 2. Multiple guide grooves 215 are symmetrically arranged. In this embodiment, three pairs are symmetrically arranged. Each guide groove 215 is provided with a spring 216 fixedly connected to the two sides of the movable cover 211 and the support part 2, so that the reset of the spring 216 is more stable.

[0031] Reference Figure 5 The knob 212 has an S-shaped groove for a pull cord 214, through which the pull cord 214 is wound around the knob 212. One end of the pull cord 214 passes over the fixing post 213 and then enters the groove, passing through two bends within the groove before connecting to the other end of the pull cord 214. The groove in the pull cord 214 ensures that the pull cord 214 remains stable and does not slip when wound.

[0032] When the catheter sheath needs to be removed, loosen knob 212 to slack the pull cord 214. This allows the movable cover 211 to be moved to both sides by the elasticity of the springs 216 on both sides, opening the opening / closing device 21. Once open, medical staff can more clearly see the position of the catheter sheath, making removal easier and faster. After removing the catheter sheath, simply close the opening / closing device 21. Tighten knob 212 and wrap the pull cord around it. As knob 212 tightens, the pull cord pulls the springs 216, causing the movable cover 211 to converge towards the center, closing the opening / closing device 21.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
