Description

Technical Field

[0001] The utility model belongs to the technical field of medical care, and in particular relates to a pressurized hemostasis device for a femoral artery. Background Art

[0002] Currently, when removing the intra-arterial catheter after femoral artery puncture, cardiac angiography and angioplasty, the doctor must press the puncture site by hand for 15 to 20 minutes, which is very strenuous. If the pressure is relaxed for a moment, it will cause arterial bleeding and hematoma, increasing the patient's pain.

[0003] In response to the above problems, the current mainstream knob compression femoral artery hemostat on the market, such as the product of Hangzhou Sanyou Walker, adopts an integral support plate structure, and opens 4 functional holes on the support plate to connect three straps to fix the legs and waist. Since the opening position and direction of the functional holes are fixed, the fixing position of the straps cannot be accurately adjusted on patients of different body shapes, which indirectly affects the force uniformity and balance of the compression point during use; such as the product of Daxin Medical under BenQ Biotechnology, its structure also adopts an integral support plate form, but only two functional holes are opened on the support plate, and the support plate area is small, thereby achieving the advantages of good direction adjustment when the strap is fixed and the overall force concentration of the support plate, but the basis of this advantage is achieved by increasing the overall length of the strap, which indirectly increases the inconvenience during use.

[0004] Therefore, the above-mentioned existing products still have the following defects: the position of the strap is fixed and cannot be adapted to patients of different heights and weights; the degree of compression cannot be adjusted by intuitive observation; after pressing, the pressing device needs to be removed and the puncture point needs to be covered with cotton cloth, which takes time to exchange and increases the risk of exposure and infection of the puncture site. Utility Model Content

[0005] The utility model aims to provide a femoral artery pressurized hemostasis device, which is provided with multiple straps with freely adjustable positions, can be adapted to patients of different body shapes, and can directly cover the puncture site with a sterile cotton block after pressing, thereby reducing the risk of infection caused by exposure of the puncture site.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pressurized hemostatic device for the femoral artery, which comprises a fixed block, a binding strap is rotatably connected to the outside of the fixed block, a through hole is provided inside the fixed block, a connecting tube is rotatably connected inside the through hole, an adjusting screw is threadedly connected inside the connecting tube, a pressure block is fixed to the end of the adjusting screw facing the through hole, a sterile foam cotton block is bonded to the end of the pressure block away from the adjusting screw, and the outside of the adjusting screw is coated with an identification layer of different colors.

[0007] Furthermore, the marking layer is coated with red, yellow and green colors in sequence along the direction toward the pressing block.

[0008] Furthermore, a rotating slot is provided on the side of the fixed block, the cross section of the rotating slot is T-shaped, and several rotating slots are provided along the axial direction of the fixed block. A moving block is rotatably connected inside each rotating slot, and the strap is sleeved on the end of the moving block away from the fixed block.

[0009] Furthermore, some of the straps are sewn with male Velcro patches or female Velcro patches at the ends away from the rotating slide slot, and the number of male Velcro patches and female Velcro patches is set to be the same.

[0010] Furthermore, a first connecting rod is fixed to the side of the connecting tube, the first connecting rod is spherical away from the end of the connecting tube, the first connecting rod is rotatably connected to a support rod away from the end of the connecting tube, the support rod is rotatably connected to a second connecting rod away from the first connecting rod, the second connecting rod is spherical toward the support rod end, and the second connecting rod is fixed on the inner wall of the through hole away from the support rod end.

[0011] Furthermore, a rubber pad is fixed to the bottom of the fixing block, and concave openings are provided on both sides of the rubber pad.

[0026] The marking layer is coated with red, yellow and green colors in the direction toward the pressing block 6, and the marking layer is not shown in the drawings.

[0027] A rubber pad 15 is also fixed to the bottom of the fixing block 1 , and concave openings 17 are provided on both sides of the rubber pad 15 .

[0028] In this embodiment, the fixing block 1 is placed at the femoral artery, and the sterile foam cotton block 7 is used to contact the femoral artery. At the same time, the adjusting screw 5 is rotated, specifically, the adjusting screw 5 is rotated clockwise. Since the adjusting screw 5 and the connecting tube 4 are threadedly connected, the adjusting screw 5 can be driven to move toward the femoral artery, thereby driving the pressing block 6 and the sterile foam cotton block 7 bonded to the pressing block 6 to move toward the femoral artery. As the adjusting screw 5 is continuously rotated, the greater the pressure applied by the sterile foam cotton block 7 to the femoral artery, the degree of pressure can be visually observed based on the surface color of the adjusting screw 5 exposed to the outside of the fixing block 1. Green to red indicate increasing pressure.

[0029] As an embodiment, a rotating groove 8 is provided on the side of the fixed block 1, and the cross-section of the rotating groove 8 is T-shaped. Several rotating grooves 8 are provided along the axial direction of the fixed block 1. Each rotating groove 8 is rotatably connected to a movable block 9, and the movable block 9 is sleeved with the strap 2 at the end away from the fixed block 1.

[0030] Some of the straps 2 are sewn with male Velcro patches 10 or female Velcro patches 11 at the ends away from the rotating slide slot 8, and the number of male Velcro patches 10 and female Velcro patches 11 is the same.

[0031] In this embodiment, the number of straps 2 is set to four, and the straps 2 themselves are made of elastic fiber. Velcro male patches 10 are sewn on two of the straps 2, and Velcro female patches 11 are sewn on the other two straps 2. Then, according to the actual situation of different patients, the position of the movable block 9 is rotated and adjusted, and the four straps 2 are cross-sticked at the patient's waist or thighs to fix the fixed block 1.

[0032] After the fixing block 1 is fixed, the rubber pad 15 abuts around the fixing position and directly abuts against the patient's skin. As shown in the figure, the rubber pad 15 is fixed to the bottom of the fixing block 1 to reduce the discomfort caused by the abutment of the fixing block 1.

[0033] As an embodiment, a first connecting rod 12 is fixed to the side of the connecting tube 4, and the end of the first connecting rod 12 away from the connecting tube 4 is spherical. The end of the first connecting rod 12 away from the connecting tube 4 is rotatably connected to a support rod 13, and the support rod 13 is rotatably connected to a second connecting rod 14 away from the first connecting rod 12. The second connecting rod 14 is spherical toward the end of the support rod 13, and the end of the second connecting rod 14 away from the support rod 13 is fixed to the inner wall of the through hole 3.

[0034] The first connecting rod 12 and the support rod 13 are spherically connected, so that the first connecting rod 12 can rotate freely along the connection with the support rod 13, and the connection between the support rod 13 and the second connecting rod 14 can also rotate freely. The first connecting rod 12 is symmetrically arranged on the side of the connecting tube 4, so the connecting tube 4 can rotate in different directions in the through hole 3, and at the same time drive the adjusting screw 5 to rotate in different directions, so as to adjust the position of the pressure block 6.

[0035] Among them, the side of the sterile foam cotton block 7 away from the adjusting screw 5 is a sticky surface, and the sticky surface is covered with release paper. An extended cotton plate 16 is fixed to the side of the sterile foam cotton block 7, and the extended cotton plate 16 is symmetrically arranged about the middle of the sterile foam cotton block 7.

[0036] When in use, place the fixing block 1 at the femoral artery, fix the fixing plate on the patient's leg by adjusting the position of the bandage 2, turn the adjusting screw 5 to drive the pressing block 6 to contact the sterile foam cotton block 7 at the puncture site to stop bleeding, press the adjusting screw 5 according to the required time, and observe the pressure through the color identification layer on the adjusting screw 5. After the pressing is completed, press the extended cotton plates 16 on both sides of the sterile foam cotton block 7 along the concave opening 17 of the rubber pad 15 with your fingers, and rotate the adjusting screw 5 counterclockwise at the same time, the sterile foam cotton block 7 is separated from the pressing block 6. At this time, the sterile foam cotton block 7 stays on the puncture site to cover the puncture site, and then fold the extended cotton plate 16 to the upper surface of the sterile foam cotton block 7 to cover its bonding surface with the pressing block 6 to avoid sticking of the upper surface of the sterile foam cotton block 7; when used next time, re-bond a sterile foam cotton block 7 and it can be used again.

[0037] The extended cotton block and the sterile foam cotton block 7 are made of the same material and are made in one piece.
