Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary tools technology, and in particular to a postoperative pressure hemostasis device for the iliac region. Background Technology

[0002] In oral and maxillofacial surgery, autologous bone grafting is often used to repair mandibular defects. The iliac bone is large in volume, has a certain natural curvature and thickness, and is rich in cancellous bone, which can be adapted to restore the shape of the mandibular body and angle. However, wound care in the iliac bone area is important. The iliac bone has a large amount of cancellous bone reticular structure. After bone harvesting, many small blood vessels are not anastomosed, which can easily lead to bleeding. In addition, in order to prevent fluid accumulation at the bone harvesting site and avoid the formation of dead space, it is necessary to use an abdominal binder for pressure bandaging until suture removal after surgery to apply pressure to the patient's wound for hemostasis and accelerate the patient's recovery.

[0003] A search revealed that Chinese Patent Publication No. CN219538417U discloses a compression hemostasis device for postoperative iliac region surgery. The device includes a bandage and a saline bag positioning piece wrapped around the body. The saline bag is fixed to the body part by the fastening Velcro of the bandage and the positioning Velcro of the saline bag positioning piece. The bandage is an elastic compression band, and the compression intensity and direction of the elastic compression band can be adjusted as needed to ensure the quality of compression, fix the saline bag, and prevent the saline bag from shifting and affecting the compression effect.

[0004] In actual use, the aforementioned pressure hemostasis device, when applying pressure to the patient's wound, if active bleeding persists after pressure is applied (such as the dressing being continuously soaked in blood), requires removing the device, checking the wound, and replacing it with a more effective hemostatic material. However, the device uses Velcro for adjustment and fixation, and when it is removed and re-fixed, the position and tightness of the bandage need to be readjusted repeatedly, prolonging the operation time. This not only affects the installation efficiency of the device but also poses a risk of secondary injury to the patient's wound. Therefore, a pressure hemostasis device for iliac surgery is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a pressure hemostasis device for iliac surgery, which aims to improve the problem in the prior art that requires repeated adjustments when the pressure hemostasis device needs to be temporarily removed and reinstalled.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a pressure hemostasis device for iliac surgery, comprising a pressure band 1, a through groove 2 at the center of the pressure band 1, a fixing hook and loop fastener 3 fixedly connected to the upper surface of the pressure band 1, a pressure plate 4 sleeved inside the through groove 2, when the pressure plate 4 is inside the through groove 2, it fills the inside of the through groove 2, the outer wall of the pressure plate 4 is in contact with the inner wall of the through groove 2, and an edge hook and loop fastener 5 is fixedly connected to the outer side of the pressure plate 4, the bottom right side of the edge hook and loop fastener 5 is fixedly connected to the upper surface of the fixing hook and loop fastener 3, and the bottom surface of the edge hook and loop fastener 5 is bonded to the upper surface of the fixing hook and loop fastener 3, thereby fully limiting the pressure plate 4, so that when the pressure band 1 is compressed to compress and stop bleeding at the patient's iliac wound, it can simultaneously drive the pressure plate 4 to compress the wound position. At the same time, the edge hook and loop fastener 5 can be torn open around the fixed position of the right side of the fixing hook and loop fastener 3, thereby allowing for quick removal and replacement of dressings or tourniquets at the patient's wound position without disassembling the entire device.

[0033] The bottom of the pressure pad 4 is detachably fitted with a saline bag 6. By adjusting the number or weight of the saline bags 6, the pressure can be flexibly controlled to meet the hemostasis needs of different patients. The saline bags 6 are directly pressed onto the blood vessel or tissue incision to promote local thrombus formation and accelerate hemostasis. The saline bags 6 are attached to the bottom of the pressure pad 4 with Velcro, allowing for quick adjustment and replacement of the saline bags 6 on the bottom of the pressure pad 4 to fit the area and location of the patient's wound, avoiding waste or insufficient coverage.

[0034] Reference Figures 3-5 An elastic band 7 is fixedly connected to the upper left side of the fixed hook and loop fastener 3. A connecting strip 8 is fixedly connected to the left end of the elastic band 7. A segmented hook and loop fastener strip 9 is fixedly connected to the left side of the connecting strip 8. The bottom surface of the segmented hook and loop fastener strip 9 is bonded to the upper surface of the fixed hook and loop fastener 3. When medical staff pull the connecting strip 8 through the segmented hook and loop fastener strip 9, the elastic band 7 will be stretched, causing the elastic band 7 to undergo elastic deformation.

[0035] Reference Figure 2 , Figure 4 and Figure 5A loop-shaped braided frame 10 is fixedly connected to the upper surface of the fastener 3, and a pull tab 11 is fixedly connected to the left side of the upper surface of the edge fastener 5. The loop-shaped braided frame 10 is sleeved on the outside of the edge fastener 5. The loop-shaped braided frame 10 can limit the position of the edge fastener 5. When installing the pressure plate 4, the edge fastener 5 can be directly aligned with the inside of the loop-shaped braided frame 10 and inserted, so that the pressure plate 4 can be stably inserted into the through groove 2, avoiding displacement that would affect the pressure effect. At the same time, the staff can directly pull the left end of the edge fastener 5 through the pull tab 11, avoiding the need to fasten the left end of the edge fastener 5 to open it, thereby reducing the impact on the patient's wound.

[0036] A U-shaped braided frame 12 is fixedly connected to the left side of the upper surface of the fixed hook and loop fastener 3. The U-shaped braided frame 12 is sleeved on the outside of the connecting strip 8. A pull strip 13 is fixedly connected to the right side of the upper surface of the segmented hook and loop fastener 9. The U-shaped braided frame 12 can limit the position of the connecting strip 8. After the left end of the segmented hook and loop fastener 9 is pulled open to relieve the pressure on the wound in the patient's iliac region, when it is reinstalled, the connecting strip 8 can be directly aligned with the inside of the U-shaped braided frame 12, so that the segmented hook and loop fastener 9 can be quickly reset to its original position and accurately positioned. This further reduces the reset adjustment time of the segmented hook and loop fastener 9. Medical staff can directly pull open the left end of the segmented hook and loop fastener 9 through the pull strip 13 without having to fasten the connecting strip 8.

[0037] Working principle: Align the saline bag 6 with the wound on the patient's iliac region, then attach the pressure band 1 to the patient's body, and then wrap the segmented hook and loop tape 9 around the patient's body, so that the right end of the segmented hook and loop tape 9 is bonded to the right side of the upper surface of the fixing hook and loop tape 3, so that the device is tied to the patient's body. By controlling the stretching length of the segmented hook and loop tape 9 and the bonding position with the fixing hook and loop tape 3, the pressure intensity and direction can be adjusted to suit different patients, ensure the quality of pressure, and achieve fixation and pressure of the saline bag 6, preventing the saline bag 6 from shifting and affecting the compression effect.

[0038] If active bleeding persists after a period of use (e.g., the dressing remains soaked in blood), medical staff can first use the pull strip 13 to loosen the adhesion between the left end of the segmented hook and loop fastener 9 and the fixed hook and loop fastener 3. After fully loosening, the medical staff should slowly release the left end of the segmented hook and loop fastener 9 to avoid sudden pressure drop that could cause a recurrence of heavy bleeding at the patient's wound. After loosening, the left end of the segmented hook and loop fastener 9 can be released directly. The elastic band 7 ensures the connection between the connecting strip 8 and the fixed hook and loop fastener 3, preventing it from falling off or being lost, which could lead to the device detaching from the patient. When pulling the left end of the segmented hook and loop fastener 9, the elastic band 7 can be stretched, which can avoid excessive pressure on the pressure band 1, thereby reducing the impact on the patient's wound. Then, the pull tab 11 can be used to pull open the edge of the hook and loop fastener. By attaching the Velcro 5 and the pressure pad 4, medical staff can quickly change dressings or tourniquets through the through-slot 2. After the change, the edge of the Velcro 5 can be aligned with the inside of the U-shaped braided frame 10 and inserted, allowing the pressure pad 4 to quickly enter the through-slot 2 for filling, preventing displacement. Finally, the left end of the segmented Velcro strip 9 is pulled back to its original position to restore adhesion to the fixing Velcro 3, thus quickly completing the reinstallation of the device. Since the segmented right end of the segmented Velcro strip 9 is not removed, only the left end of the segmented Velcro strip 9 needs to be reset, reducing the difficulty of operation and improving installation efficiency. At the same time, the U-shaped braided frame 12 can work with the connecting strip 8 to quickly position the left end of the segmented Velcro strip 9, further improving the efficiency of secondary installation and avoiding the need to repeatedly readjust the position and tightness of the straps.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
