Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a postoperative vascular bandage with adjustable local pressure. Background Technology

[0002] Neck vascular surgery is a surgical procedure performed on vascular lesions such as the carotid artery and vertebral artery in the neck. It is mainly used to solve problems such as vascular stenosis, occlusion, aneurysm, and vascular malformation. It is an important means of preventing and treating cardiovascular and cerebrovascular diseases such as cerebral ischemia and cerebral infarction.

[0003] Neck vascular surgery often involves a minimally invasive incision on the side of the neck. Specialized instruments are used to clear narrowed blood vessels, remove lesions, or implant stents. Vascular anastomosis and patch repair can also be used to repair the vessel wall. After surgery, a medical-grade elastic bandage, primarily made of elastic fibers, provides both fit and support. It conforms to the curve of the neck and wraps around the wound, applying pressure to stop bleeding, securing the dressing, and reducing wound bleeding and swelling. For example, the existing Chinese utility model patent with publication number CN212997026U, "A Child's Neck Bandage," utilizes a commissive pouch and a commissive pouch... The sandbags inside the bandage apply pressure to the wound when the main bandage is wrapped around the child's neck and armpits. This reduces the need for the bandage to be wrapped multiple times around the neck. However, the sandbags have a fixed weight and are relatively hard. Therefore, when bandaging a patient, it is impossible to precisely adjust the pressure on the wound according to postoperative care needs and the patient's tolerance. If the pressure is too low, it will not achieve the effect of stopping bleeding or adhering to the wound surface, and may easily cause bleeding, swelling, and delay wound healing. If the pressure is too high, it will compress the blood vessels in the neck and surrounding tissues, affecting local blood supply, and may also cause stinging and redness of the skin. Utility Model Content

[0004] The purpose of this invention is to provide a vascular postoperative bandage with adjustable local pressure, which can precisely adjust the pressure at the wound site, adapt to postoperative care needs and patient adaptability, and effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An adjustable local pressure postoperative vascular bandage includes a bandage with a wound covering cloth at its center. Adhesive layers are coated on both sides of the wound covering cloth, and release paper is attached. A cover is fixedly connected to the lower end of the wound covering cloth, and a mounting ring is fixedly connected to the middle of the cover. A silicone pad is movably connected between the wound covering cloth and the cover. A radially moving ring is fixedly connected to the lower end of the silicone pad and is inserted into the mounting ring. An adjusting screw is threaded into the radially moving ring. A slot is formed at the lower end of the adjusting screw, and several transmission grooves are formed circumferentially on the inner side of the slot. A spring is fixedly connected to the transmission groove. An adjusting knob is movably connected to the outer side of the mounting ring, and a plug is movably connected to the adjusting knob.

[0007] As a further preferred embodiment of this utility model, the mounting ring has a rotating groove along its outer contour for mounting the adjustment knob, and the mounting ring has several guide grooves circumferentially arranged on its inner side to restrict the axial movement of the radial moving ring, so that the radial moving ring moves radially within the mounting ring.

[0008] As a further preferred embodiment of this utility model, a plurality of guide blocks are fixedly connected to the outer side of the radial moving ring. The guide blocks are inserted into the corresponding guide grooves, so that when the adjusting screw rotates in the radial moving ring, the radial movement of the radial moving ring in the mounting ring can be controlled.

[0009] As a further preferred embodiment of this utility model, the spring is V-shaped, and the two sides of the spring abut against one side of the transmission groove, thereby forming a clearance fit with the transmission block on the outside of the insert block and providing power for the reset of the transmission block.

[0010] As a further preferred embodiment of this utility model, a fixing ring is fixedly connected to the inner side of the adjusting knob, and several gap grooves are opened at the bottom of the adjusting knob. The longitudinal section of the gap groove is L-shaped. The adjusting knob is rotatably connected to the outer side of the mounting ring through the fixing ring, and the fixing ring is rotatably connected in the rotating groove. When the adjusting knob is manually rotated on the outer side of the mounting ring, the adjusting knob can drive the adjusting screw to rotate in the radial moving ring, thereby controlling the radial movement of the radial moving ring in the mounting ring, so that the silicone pad gradually applies pressure or reduces pressure on the wound covering cloth towards the patient's neck.

[0011] As a further preferred embodiment of this utility model, an insert block is fixedly connected to the bottom of the adjusting knob located inside the adjusting screw block. A transmission block with the same number as the transmission groove is fixedly connected to the outside of the insert block. The transmission block extends outward into the corresponding transmission groove. Thus, when the adjusting knob is accidentally touched, several gap grooves inside the adjusting knob are in clearance fit with several gap blocks. That is, the gap groove can move a certain distance on the gap block without causing the gap block to rotate. At the same time, the insert block drives the outer transmission block to move in the corresponding transmission groove and compresses and deforms one side of the spring piece, providing power for the subsequent restoration of the gap groove to the initial position on the gap block.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, the pressure at the wound site can be flexibly adjusted by rotating the adjustment knob in conjunction with the adjustment screw, radial moving ring, and silicone pad. The pressure can be controlled according to the needs of different postoperative care stages and the patient's actual adaptability, ensuring effective hemostasis and adherence to the wound surface while avoiding excessive pressure that could compress neck blood vessels or damage the skin. The adjustment screw, through several gap blocks at its bottom and several gap grooves at the bottom of the adjustment knob, prevents the adjustment knob from being accidentally touched, thus preventing pressure deviation and acting as a preventative measure.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figures 1-3 As shown, this utility model provides an adjustable local pressure postoperative vascular bandage, including a bandage 1. A wound covering cloth 3 is provided at the upper middle position of the bandage 1. Adhesive layers are coated on both sides of the bandage 1, and release paper 2 is attached. A cover 4 is fixedly connected to the lower end of the wound covering cloth 3. An installation ring 5 is fixedly connected to the middle position of the cover 4. A silicone pad 6 is movably connected between the wound covering cloth 3 and the cover 4. A radial moving ring 7 is fixedly connected to the lower end of the silicone pad 6 and is inserted into the installation ring 5. An adjusting screw block 8 is threadedly connected to the radial moving ring 7. A slot 9 is opened at the lower end of the adjusting screw block 8. Several transmission grooves 10 are opened circumferentially on the inner side of the slot 9. A spring piece 11 is fixedly connected in the transmission groove 10. An adjusting knob 12 is movably connected to the outer side of the installation ring 5. A plug block 17 is movably connected to the adjusting knob 12.

[0022] like Figures 2-5 As shown, the mounting ring 5 has a rotating groove 13 along its outer contour for mounting the adjusting knob 12. Several guide grooves 14 are circumferentially formed on the inner side of the mounting ring 5 to restrict the axial movement of the radial moving ring 7, allowing the radial moving ring 7 to move radially within the mounting ring 5. Several guide blocks 15 are fixedly connected to the outer side of the radial moving ring 7. The guide blocks 15 are inserted into the corresponding guide grooves 14, so that when the adjusting screw block 8 rotates within the radial moving ring 7, the radial movement of the radial moving ring 7 within the mounting ring 5 can be controlled. The spring piece 11 is V-shaped, with its two sides abutting against one side of the transmission groove 10, thus forming a clearance fit with the transmission block 18 on the outer side of the insert block 17 and providing power for the reset of the transmission block 18.

[0023] like Figures 2-5As shown, a fixing ring 19 is fixedly connected to the inner side of the adjusting knob 12. Several gap grooves 20 are formed at the bottom of the adjusting knob 12, with an L-shaped longitudinal section. The adjusting knob 12 is rotatably connected to the outer side of the mounting ring 5 via the fixing ring 19, and the fixing ring 19 is rotatably connected to the rotating groove 13. When the adjusting knob 12 is manually rotated outside the mounting ring 5, it causes the adjusting knob 12 to drive the adjusting screw block 8 to rotate within the radially moving ring 7, thereby controlling the radial movement of the radially moving ring 7 within the mounting ring 5. This allows the silicone pad 6 to gradually apply or reduce pressure on the wound covering cloth 3 towards the patient's neck. The adjusting screw block 8 is located inside the adjusting screw block 8. An insert block 17 is fixedly connected to the bottom of the adjustment knob 12. A transmission block 18, the same number as the transmission groove 10, is fixedly connected to the outside of the insert block 17. The transmission block 18 extends outward into the corresponding transmission groove 10. Thus, when the adjustment knob 12 is accidentally touched, several gap grooves 20 inside the adjustment knob 12 are in clearance fit with several gap blocks 16. That is, the gap groove 20 can move a certain distance on the gap block 16 without causing the gap block 16 to rotate. At the same time, the insert block 17 drives the outer transmission block 18 to move in the corresponding transmission groove 10 and squeezes and deforms one side of the spring piece 11, providing power for the subsequent restoration of the gap groove 20 to the initial position on the gap block 16.

[0024] It should be noted that this utility model is a vascular postoperative bandage with adjustable local pressure. When using it, first tear off the release paper 2, align the wound covering cloth 3 in the middle of the bandage 1 with the dressing pad at the wound site of the vascular surgery on the patient's neck, and use the adhesive layers on both sides of the bandage 1 to fix the whole to the patient's neck, so that the wound covering cloth 3 fits tightly to the wound area, and complete the basic bandaging and fixation operation.

[0025] When adjusting the pressure, manually rotate the adjusting knob 12 on the outside of the mounting ring 5. The adjusting knob 12 rotates on the outside of the mounting ring 5 via the fixing ring 19, and simultaneously drives the insert block 17 and the transmission block 18 to rotate. After the transmission block 18 abuts against the side inside the transmission groove 10 and the side inside the gap groove 20 abuts against the side of the corresponding gap block 16, it will drive the adjusting screw block 8 to rotate in the radial moving ring 7. The guide block 15 on the outside of the radial moving ring 7 is limited by the guide groove 14 on the inside of the mounting ring 5 and cannot rotate axially with the adjusting screw block 8. It can only move radially in a straight line along the guide groove 14, which in turn drives the silicone pad 6 to move radially in sync. Therefore, when the silicone pad 6 moves towards the wound covering cloth 3, it will form a continuous pushing force on the wound covering cloth 3, so that the pressure applied by the wound covering cloth 3 to the patient's wound gradually increases. When the adjusting knob 12 is rotated in the opposite direction, the silicone pad 6 moves away from the wound covering cloth 3. As the wound is moved in the direction of the wound covering cloth 3, the pressure on the wound gradually decreases, thereby achieving the goal of precisely controlling the wound pressure according to postoperative care needs and the patient's adaptability.

[0026] If the adjustment knob 12 is accidentally touched during routine care, the gap groove 20 inside the adjustment knob 12 will move a small distance on the gap block 16, without directly driving the gap block 16 and the adjustment screw block 8 to rotate. At the same time, the insert block 17 drives the transmission block 18 to squeeze the V-shaped spring piece 11 in the transmission groove 10, causing the spring piece 11 to deform. After the external force disappears, the reset elasticity of the spring piece 11 will drive the transmission block 18 back to its original position, thereby allowing the adjustment knob 12 to return to its initial position, avoiding accidental touch that could cause the wound pressure to shift, and achieving the protection effect of preventing accidental touch.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
