Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a sandbag fixing device. Background Technology

[0002] With the rapid development of medical technology, minimally invasive interventional surgery techniques are increasingly being used in disease treatment. Femoral artery puncture is an important procedure in vascular interventional therapy. Effective compression and hemostasis of the femoral artery puncture site after surgery is one of the means to prevent postoperative complications. The commonly used hemostasis method is to use multiple layers of bandages to wrap the femoral artery puncture site and apply a heavy object to compress and stop the bleeding.

[0003] The principle of sandbag compression hemostasis is to use the weight of the sandbag to act on the capillaries in the tissue to resist blood flow dynamics, slow down blood flow speed, activate clotting factors, thereby controlling and preventing bleeding, effectively compressing the wound, and preventing incision bleeding, swelling and reducing pain.

[0004] In clinical practice, when using sandbags for compression hemostasis, medical staff place the sandbag directly on the puncture site. However, due to the uneven surface of the patient's hip, the sandbag is unstable and tends to shift. Even small movements by the patient can cause the sandbag to shift, failing to achieve vertical compression hemostasis at the puncture site. Furthermore, since sandbag compression hemostasis takes a long time, medical staff cannot be with the patient at all times. During compression hemostasis, the patient's limb needs to be immobilized for an extended period. If the patient unintentionally makes a large movement that causes the sandbag to shift or even fall off, traditional sandbag fixation devices cannot allow the patient to independently adjust the sandbag's position, leading to bleeding and swelling at the puncture site, and potentially affecting the patient's postoperative recovery. Utility Model Content

[0005] This utility model provides a sandbag fixing device to solve the aforementioned technical problems.

[0006] The present invention adopts the following technical solution: it includes a waist strap and a leg strap. The waist strap has a cavity inside, and a movable locking component and a fixing component are respectively provided in the cavity. The leg strap is located below the waist strap. Both ends of the leg strap are provided with first Velcro. The leg strap is provided with a sandbag mounting and fixing component. The side end of the leg strap is provided with multiple connecting straps that can be connected to the waist strap.

[0007] Furthermore, the movable locking assembly includes a rack plate, a gear, a rotating shaft, a rotating block, a locking block, a locking hole, and a limiting block. The rack plate is located inside the cavity of the waist strap, and the volume of the rack plate is smaller than the capacity of the cavity. The gear is located inside the cavity and meshes with the rack plate. The limiting block is located at the side end of the waist strap and its position corresponds to the gear. The rotating shaft is rotatably mounted on the waist strap, and its two ends are fixedly connected to the gear and the limiting block, respectively. The cross-section of the rotating shaft at one end inside the waist strap is circular, and the cross-section of the rotating shaft extending to the outside of the waist strap is regular hexagonal. The rotating block is fitted onto the hexagonal part of the rotating shaft and can slide on this part. The locking block is located on the rotating block facing the gear, and one end of the locking block is fixedly connected to the edge of the rotating block. The side end of the waist strap is provided with multiple locking holes that correspond to the rotating blocks.

[0008] Furthermore, the fixing component includes multiple threading bags, connecting straps, and multiple female buckles. The multiple threading bags are fixedly disposed on the side end of the rack plate, and the multiple female buckles are located at the top of the connecting straps. Each connecting strap is provided with a buckle hole that matches the multiple female buckles, and the outer diameter of each connecting strap is smaller than the inner diameter of the threading bags.

[0009] Furthermore, the sandbag installation and fixing assembly includes two second Velcro straps and a placement box. The placement box is located at the side end of the leg strap, and the two second Velcro straps are respectively located at both ends of the edge of the placement box, and the two second Velcro straps can be glued to each other.

[0010] Furthermore, the waist straps are provided with a textured adhesive tape and a hook-and-loop adhesive tape at each end, which can be bonded together.

[0011] Furthermore, elastic bands are provided on both sides of the placement box.

[0012] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0013] By stretching the connecting strap, the leg strap at one end is displaced, thereby adjusting the position of the sandbag on the leg strap. When the sandbag is adjusted to the appropriate position, the female buckle on the connecting strap is installed into the corresponding buckle hole, so that the connecting strap cannot be stretched again, thus completing the fixation of the leg strap. This limits the position of the sandbag on the leg strap, preventing the sandbag from shifting or falling off when the patient performs small movements.

[0014] If the patient unintentionally moves too much and causes the sandbag to shift, the patient can slide the rotating block on the end of the rotating shaft that extends to the outside of the waist strap until the locking block on the rotating block completely separates from the locking hole on the side end of the waist strap. At this point, the patient can rotate the rotating block, which will cause the gear at one end of the rotating block to rotate. As the gear rotates, the rack plate meshing with it begins to move horizontally, thereby moving the entire fixation assembly horizontally. Since the connecting strap on the fixation assembly is connected to the side end of the leg strap, it can further adjust the position of the leg strap. The sandbag position can be adjusted. Compared to existing sandbag fixing devices, where the sandbag cannot provide vertical pressure to the puncture site for hemostasis when the patient is unattended and the sandbag shifts, resulting in poor hemostasis or even hematoma, this invention allows the patient to independently fine-tune the position of the sandbag through a movable locking component on the waist strap. This prevents poor hemostasis at the puncture site due to the lack of adjustment when the sandbag shifts, and saves time and energy for medical staff and patients' families.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0026] This utility model provides a sandbag fixing device, including a waist strap 1 and a leg strap 2. The waist strap 1 has a cavity 11 inside, and a movable locking component 3 and a fixing component 4 are respectively provided in the cavity 11. The leg strap 2 is located below the waist strap 1. Both ends of the leg strap 2 are provided with first Velcro 21. The leg strap 2 is provided with a sandbag mounting and fixing component 5. The side end of the leg strap 2 is provided with a plurality of connecting straps 22 that can be connected to the waist strap 1.

[0027] The movable locking assembly 3 includes a rack plate 31, a gear 32, a rotating shaft 33, a rotating block 34, a locking block 35, a locking hole 36, and a limiting block 37. The rack plate 31 is located inside the cavity 11 of the waist strap 1, and the volume of the rack plate 31 is smaller than the capacity of the cavity 11. The gear 32 is located inside the cavity 11 and meshes with the rack plate 31. The limiting block 37 is located at the side end of the waist strap 1 and its position corresponds to that of the gear 32. The rotating shaft 33 is rotatably mounted on the waist strap 1, and both ends of the rotating shaft 33 are respectively connected to the gear 32 and the limiting block 37. The position block 37 is fixedly connected. The cross-section of the rotating shaft 33 inside the waist strap 1 is circular, and the cross-section of the rotating shaft 33 extending to the outside of the waist strap 1 is regular hexagonal. The rotating block 34 is sleeved on the part of the rotating shaft 33 with a regular hexagonal cross-section and can slide on this part. The locking block 35 is located on the side of the rotating block 34 facing the gear 32, and one end of the locking block 35 is fixedly connected to the edge of the rotating block 34. The side end of the waist strap 1 is provided with a plurality of locking holes 36 that correspond to the rotating block 34.

[0028] The fixing component 4 includes multiple threading pockets 41 and multiple female buckles 42. The multiple threading pockets 41 are fixedly disposed on the side end of the rack plate 31, and the multiple female buckles 42 are located at the top end of the connecting belt 22. Each connecting belt 22 is provided with a buckle hole 43 that is adapted to the multiple female buckles 42. The outer diameter of each connecting belt 22 is smaller than the inner diameter of the threading pockets 41.

[0029] When in use, medical staff attach the leg strap 2 containing the sandbag to the puncture site on the patient's leg. Since the outer diameter of the connecting strap 22 on the leg strap 2 is smaller than the inner diameter of the insertion bag 41, the female buckle 42 at one end of the connecting strap 22 can be passed through its corresponding insertion bag 41. At this time, by stretching the connecting strap 22, the leg strap 2 at one end will be displaced, thereby adjusting the position of the sandbag on the leg strap 2. When the sandbag is adjusted to the appropriate position, the female buckle 42 on the connecting strap 22 is installed into its corresponding buckle hole 43, so that the connecting strap 22 cannot be stretched again, thus completing the fixation of the leg strap 2. This can limit the position of the sandbag on the leg strap 2 and prevent the sandbag from shifting or falling off when the patient makes small movements.

[0030] If the patient unintentionally engages in strenuous activity that causes the sandbag to shift, the patient can slide the rotating block 34 on the end of the rotating shaft 43 extending to the outside of the waist strap 1 until the locking block 35 on the rotating block 34 is completely separated from the locking hole 36 on the side of the waist strap 1. At this point, the patient can rotate the rotating block 34, thereby causing the gear 32 at one end of the rotating block 34 to rotate. As the gear 32 rotates, the rack plate 31 meshing with it begins to move horizontally, thereby driving the entire fixing assembly 4 to begin horizontal movement. Since the connecting strap 22 is connected to the side of the leg strap 2, Furthermore, the position of the sandbag on the leg strap 2 can be adjusted. Compared with the existing sandbag fixing device, when the patient is unattended and the sandbag is displaced, the displaced sandbag cannot provide vertical pressure to the puncture point for hemostasis, resulting in poor hemostasis and even hematoma. This utility model, through the movable locking component 3 set on the waist strap 1, allows the patient to independently fine-tune the position of the sandbag, preventing poor hemostasis at the puncture point due to lack of adjustment when the sandbag is displaced. It also saves time and energy for medical staff and patients' families.

[0031] Preferably, the sandbag installation and fixing component 5 includes two second Velcro straps 51 and a placement box 52. The placement box 52 is located at the side end of the leg strap 2, and the two second Velcro straps 51 are respectively located at both ends of the edge of the placement box 52. The two second Velcro straps 51 can be glued together. When medical staff install the leg strap 2, they can place the leg strap 2 at the patient's puncture point and fix the leg strap 2 to the patient's leg by the first Velcro straps 21 at both ends of the leg strap 2 being glued together. For bleeding at the puncture site, a sandbag of appropriate weight can be placed in the placement box 52 and connected to each other by the second Velcro 51 at both ends of the puncture site. This limits the position of the sandbag in the placement box 52, preventing it from shaking due to insufficient weight, which would affect the hemostatic effect. It also prevents the sandbag from directly contacting the puncture site, which could cause blood from the puncture site to seep into the sandbag. If a sandbag soaked in blood is reused, it may cause cross-infection at the puncture site, affecting the reuse of the sandbag.

[0032] Preferably, the waist strap 1 has a textured adhesive tape 12 and a hook-and-loop adhesive tape 13 at each end that can be adhered to each other. Through the adhesion of the textured adhesive tape 12 and the hook-and-loop adhesive tape 13 at each end of the waist strap 1, the waist strap 1 can be fixed to the patient's waist, thereby limiting the position of the fixing component 4 on the waist strap 1.

[0033] Preferably, elastic bands 53 are provided on both sides of the placement box 52. When installing the leg strap 2 on an obese patient, the elastic bands 53 on both sides of the placement box 52 can stretch the overall length of the leg strap 2, preventing the leg strap 2 from being unable to be fixed to the patient's leg due to insufficient length, thus affecting the effect of the sandbag on the vertical pressure hemostasis of the puncture point.

[0034] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
