DETAILED DESCRIPTION
[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0028] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0029] Example:
[0030] Reference Figure 1-Figure 5 The embodiment of the utility model provides a compression hemostasis device, including a device block 1, and also including: an arc-shaped concave surface 2, which is arranged at the lower end of the device block 1, and the arc-shaped concave surface 2 can make the bottom of the device block 1 fit more easily with the skin of the patient's arm;
[0031] Among them, a soft rubber pad 3 fixedly connected to the arcuate concave surface 2 of the device block 1 is attached; a plurality of vertical holes 4 in a rectangular array are all arranged at the upper end of the device block 1, and the number of the horizontal array and the number of the vertical array of the vertical holes 4 are both cardinality; the preferred number of the present application is 5; wherein, the inner bottoms of the plurality of vertical holes 4 are longitudinally slidably connected with a top rod 6 pressed against the upper end surface of the rubber pad 3, and the upper end of the vertical hole 4 is provided with an adjusting part for driving the top rod 6 to move up and down; a fixing component is arranged on both sides of the device block 1, and when in use, the fixing component and the device block 1 are in a circular ring shape.
[0032] Specifically, when in use, the device block 1 can be fixed on the patient's arm by the fixing component, and one of the push rods 6 can be slid downward by the adjustment part, and the push rod 6 can make the local position of the rubber pad 3 protrude toward the patient's skin (such as Figure 4 As shown in the figure, the pressure of the push rod 6 will make the rubber pad 3 press against the wound to stop bleeding. When the wound is long, the adjustment part makes multiple push rods 6 distributed in a line slide downward at the same time. Since the rubber pad 3 has elastic extensibility, the local position of the rubber pad 3 will be raised in a line (as shown in the figure). Figure 5 As shown), instead of multiple linearly distributed convex points, it can press long strip wounds, so wounds of different shapes can be pressed as needed, which is more flexible and convenient to use and ensures the hemostatic effect; in practice, as needed, multiple push rods 6 can also make the rubber pad 3 protrude in any shape, such as a C shape or a V shape.
[0033] The adjusting part in the pressing hemostasis device includes a first screw rod 5 threadedly connected to the upper end of the vertical hole 4, and a push rod 6 is rotatably connected to the lower end of the first screw rod 5; when it is necessary to move the push rod 6 toward the rubber pad 3, the first screw rod 5 is rotated, and the first screw 5 will slide downward in the vertical hole 4, thereby driving the push rod 6 to press the rubber pad 3. When the push rod 6 needs to be reset, the first screw 5 can be reversed; in practice, since each first screw rod 5 can be rotated independently, the telescopic length of each push rod 6 can be adjusted, which is more flexible.
[0034] The top of the first screw rod 5 is fixedly connected with a turning handle 7, and the outer wall of the turning handle 7 is provided with anti-skid patterns. It is more convenient and labor-saving to rotate the first screw rod 5 by using the turning handle 7 with anti-skid patterns.
[0035] The fixing components in the pressing hemostasis device include a main elastic rope 10 fixedly connected to both sides of the device block 1, and both sides of the device block 1 are connected to auxiliary elastic ropes 11 through an adjustment part. The main elastic rope 10 and the auxiliary elastic rope 11 both have elastic force; wherein a gap is provided between the main elastic rope 10 and the auxiliary elastic rope 11, and the ends of the two groups of main elastic ropes 10 and the auxiliary elastic ropes 11 are connected by a magic band 12.
[0036] Specifically, when the device block 1 needs to be fixed on the arm, the device block 1 is placed on the arm, and then the two sets of main elastic ropes 10 and the auxiliary elastic ropes 11 are wrapped around the arm, and finally the main elastic ropes 10 and the auxiliary elastic ropes 11 are fixedly connected by the magic belt 12. At this time, the device block 1 is fixed on the arm under the elastic force of the main elastic ropes 10 and the auxiliary elastic ropes 11, so that the device block 1 is easy to fix and has high stability.
[0037] The adjusting part in the pressing hemostasis device includes an internal threaded tube 13 fixedly connected to the outer wall of the device block 1, and the internal threaded tube 13 is internally threaded with a second screw 14; wherein, the auxiliary elastic rope 11 is fixedly connected to one end of the device block 1 with a connector 15, and the end of the second screw 14 is rotatably connected to the connector 15.
[0038] Since the shape of the arm is mostly conical, by rotating the second screw 14, the second screw 14 is returned to the internal threaded tube 13, and the circle formed by the two secondary elastic ropes 11 will reduce in diameter. At this time, the main elastic rope 10 and the secondary elastic rope 11 will form a conical ring body, which can make the main elastic rope 10 and the secondary elastic rope 11 fit the arm more closely, thereby improving the force uniformity of the arm, indirectly improving the stability of the device block 1, and making it less likely to have position deviation during the pressing and hemostasis process; when the second screw 14 is reversed, the second screw 14 will extend out of the internal threaded tube 13, and the circle formed by the two secondary elastic ropes 11 will increase in diameter, so that the main elastic rope 10 and the secondary elastic rope 11 can be suitable for different arms and are more flexible to use.
[0039] The outer wall of the second screw rod 14 is fixedly connected with a turntable 16 , and the second screw rod 14 can be rotated more conveniently through the turntable 16 .
[0040] The arcuate concave surface 2 is provided with a groove 9, the lower end of the push rod 6 is arranged in the groove 9, and the adjacent push rods 6 are fixedly connected with a rubber rod 8 located in the groove 9, and the lower end surface of the rubber rod 8 is flush with the surface of the arcuate concave surface 2.
[0041] Specifically, when multiple push rods 6 press toward the rubber pad 3, two adjacent push rods 6 will drive the rubber rod 8 to press the rubber pad 3 synchronously, so that the gap between the adjacent push rods 6 will be filled with the rubber rod 8. This can make the rubber pad 3 receive a more uniform pushing pressure and prevent the rubber pad 3 from having discontinuous protrusions, so as to ensure a good pressing and hemostatic effect.
[0042] The two cross-distributed rubber rods 8 are integrally formed, which can prevent the two cross-distributed rubber rods 8 from overlapping each other, so as to ensure that the force on the rubber pad 3 is more uniform.
[0043] The rubber pad 3 , the main elastic rope 10 and the auxiliary elastic rope 11 are all made of medical silicone. The rubber pad 3 , the main elastic rope 10 and the auxiliary elastic rope 11 made of medical silicone can reduce the harm to the wound, thereby improving the overall safety.
[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
