Description

Technical Field

[0001] The present invention relates to the technical field of femoral artery hemostasis and pressurization, and in particular to an integrated device for rapid hemostasis and pressurization of a puncture point after femoral artery interventional treatment. Background Art

[0002] When medical staff perform femoral artery interventional treatment on patients, they need to puncture the patient's femoral artery with a puncture needle. The arterial blood flow rate is fast. After puncture and needle removal, the puncture point needs to be pressed to stop bleeding to prevent blood from flowing out of the puncture point. A special pressing device is needed in this process. However, the existing pressing device still has certain usage defects during use. The existing pressing device uses a sandbag as a pressure-applying device, and the weight of the sandbag contained therein is fixed. During postoperative care, different patients need different pressure strengths. If the pressure is too light, it will not have a good hemostatic care effect. If the pressure is too heavy, it will easily lead to weakened dorsalis pedis artery pulsation, cold limb extremities, pale skin and other symptoms.

[0003] The patent authorization announcement number CN215606043U discloses a femoral artery puncture point pressurization device that can fix the outer bag in both the horizontal and vertical dimensions through a first elastic band and a second elastic band. It has good stability and is not easy to shift when pressurized. A multi-layer inner bag is arranged in the outer bag, and sandbags of appropriate size can be loaded according to the required pressurization pressure, which is convenient for adjustment, and the sandbags will not produce excessive deformation and affect the pressure during use.

[0004] The patent with patent authorization announcement number CN212755780U discloses a femoral artery puncture point compression hemostasis device, which can be fixed on the compression plate. When in use, the two first fixing belts are used to fix the main body to the root of the thigh. At this time, the main body and the two first fixing belts form a ring and are sleeved on the outer periphery of the thigh, so that the cotton pad presses the femoral artery puncture point. Then the two second fixing belts are wrapped around the outer periphery of the waist and fixed, and the two third fixing belts are wrapped around the outer periphery of the corresponding positions of the leg and fixed. After fixing, the first connecting belt and the second connecting belt are ensured to be straightened, thereby achieving all-round fixation of the main body. During operation, the handle is turned to tighten the screw, thereby driving the compression plate to press the puncture point. The compression plate is rotatably connected to the screw, which can prevent the compression plate from rotating during the tightening process, which is beneficial to reduce friction on the skin around the puncture point.

[0005] For example, the patent authorization announcement number CN113197612A discloses a visual and adjustable pressure compression hemostasis device for femoral artery puncture point. By improving the structure of the existing visual and adjustable pressure compression hemostasis device for femoral artery puncture point, the improved compression hemostasis device can not only intuitively penetrate the health of the skin around the compression position, but also conveniently change the pressure force of the compression hemostasis device on the puncture point through the adjustable pressure, which can ensure efficient hemostasis while avoiding excessive pressure on the body. It is used to achieve hemostasis at the puncture point, and the compression hemostasis mechanism completes the compression hemostasis process through the adjustment effect. Due to the adjustability of the compression hemostasis mechanism, the device can be used for hemostasis in different parts of the body, or suitable for hemostasis at the puncture point positions of different people, thereby making the device more applicable. In summary, it is particularly important to design a fast hemostasis and pressurization integrated device for puncture point after femoral artery interventional treatment that is simple to operate, has no special requirements for the size and shape of the block sample, and can effectively ensure that the test plane and the clamping plane of the block sample are on the same horizontal line.

During the use of the device, the device needs to be tied to the outside of the patient's thigh with a strap, and during the tying process, the position of the pressing part needs to be manually adjusted by medical staff. During this process, it is easy for the pressing part to fail to be installed in place at one time, and multiple adjustments are required. At the same time, it is difficult to control the pressing force during installation, and multiple adjustments are required, which easily affects the rapid pressing use of the device.

A telescopic rod 5 is fixedly installed at the lower end of the motion frame 17, and a motion plate 6 is fixedly installed at the lower end of the telescopic rod 5, and an arc-shaped extrusion piece 7 is fixedly installed at the lower end of the motion plate 6; A rotating rod 8 is rotatably installed inside the moving frame 17, and a moving cylinder 9 is threadedly installed on the lower end of the rotating rod 8, and a cylindrical pressure sensor 10 is fixedly installed on the moving cylinder 9. A pressure display 14 is fixedly installed on the outer side of the support plate 1. The pressure display 14 is connected to the cylindrical pressure sensor 10 through a wire and can display the pressure exerted on the cylindrical pressure sensor 10 at all times.

[0034] An upper fixed cylinder 11 is fixedly mounted on the lower end of the moving cylinder 9 , a support spring 13 is fixedly mounted inside the lower end of the moving cylinder 9 , and a lower fixed cylinder 12 is fixedly mounted on the lower end of the support spring 13 .

[0035] The lower fixed cylinder 12 is slidably connected to the upper fixed cylinder 11, and the lower fixed cylinder 12 is fixedly connected to the upper end of the movable plate 6. At the same time, the sliding between the lower fixed cylinder 12 and the upper fixed cylinder 11 can utilize the support spring 13 to transmit pressure, and the pressure size of the patient's puncture point is detected at all times.

[0036] Combine Figure 4-Figure 6 As shown, in the embodiment of the present invention, positioning holes 15 are equidistantly provided inside the support plate 1 , and the positioning holes 15 are arranged corresponding to the movement grooves 3 , and limiting holes 16 are equidistantly provided inside the sliding hollow plate 4 .

[0037] Two sets of moving gear plates 19 are slidably installed inside the moving frame 17, and positioning rods 20 are fixedly installed at both ends of the moving gear plates 19, and the positioning rods 20 are engaged with the positioning holes 15. At the same time, the engagement of the positioning rods 20 with the positioning holes 15 can control the position of the moving frame 17.

[0038] A driving gear 21 is fixedly mounted on the outer side of the rotating rod 8 , and the driving gear 21 is meshed with the two sets of moving gear plates 19 respectively.

[0039] A fixed block 22 is fixedly mounted on the outer side of the moving gear plate 19 , and a moving rod 23 is fixedly mounted on the outer side of the fixed block 22 . Two sets of the moving rod 23 and the fixed block 22 are provided inside the moving frame 17 .

[0040] A fixed tube 24 and a vent tube 25 are fixedly installed inside the moving frame 17, and the interiors of the fixed tube 24 and the vent tube 25 are connected. A limiting rod 26 is slidably installed inside the vent tube 25, and the limiting rod 26 is engaged with the limiting hole 16, and the internal vertical cross-sectional area of the vent tube 25 is larger than the vertical cross-sectional area of the fixed tube 24. The position of the arc extrusion member 7 and the rotating rod 8 can be controlled by engaging the limiting rod 26 with the limiting hole 16 to ensure accurate control of the pressing position.

[0041] according to Figure 4-Figure 7In an embodiment of the present invention, a rotating shaft 28 is installed inside the moving plate 6, and a clamping plate 29 is fixedly installed between the two sets of rotating shafts 28, and a pushing plate 30 is fixedly installed on the upper end of the clamping plate 29. At the same time, the lower end of the clamping plate 29 is inclined near the side of the moving plate 6. The tourniquet attached to the lower end of the arc-shaped extrusion member 7 can be controlled by the clamping plate 29, so that the tourniquet is directly pressed on the puncture point.

[0042] A torsion spring 18 is sleeved on the outer side of the rotating shaft 28, and the rotating shaft 28 forms an elastic structure with the moving plate 6 through the torsion spring 18. The elastic force of the torsion spring 18 can directly limit the clamping plate 29, ensuring the convenience of the clamping plate 29 to limit the tourniquet.

[0043] Example 2 refer to Figure 5-Figure 7 In order to enable the arc-shaped extrusion member 7 to accurately squeeze the puncture point, after the device is tied to the outside of the patient's leg by the binding belt 27, the positions of the arc-shaped extrusion member 7 and the rotating rod 8 need to be fine-tuned to avoid the arc-shaped extrusion member 7 being unable to directly and accurately squeeze the puncture point. During this process, the rotating rod 8 needs to be rotated and the positioning rod 20 and the limiting rod 26 are respectively engaged with the positioning hole 15 and the limiting hole 16, so as to ensure the stability of the device in squeezing the puncture point.

[0044] Example 3 The specific use process of the integrated device for rapid hemostasis and pressurization of the puncture point after femoral artery interventional treatment provided by the present invention is as follows: First, before puncture, the device is installed on the outside of the patient's thigh through the binding belt 27, and the midpoint between the two sets of connecting rods 2 is close to the puncture position, and the two sets of support plates 1 need to be naturally parallel to the placement direction of the patient's thigh.

[0045] Second, install the tourniquet on the lower end of the arc-shaped extrusion piece 7, push the pushing plate 30 toward the telescopic rod 5 and make the rotating shaft 28 on the outside of the clamping plate 29 rotate inside the moving plate 6. At this time, fit the tourniquet to the moving plate 6 and the lower end of the arc-shaped extrusion piece 7, release the group of pushing plates 30 and use the torsion spring 18 to push the clamping plate 29 to reset, so that the clamping plate 29 cooperates with the moving plate 6 to limit and clamp one side of the tourniquet, repeat the above operation and limit and clamp the other side of the tourniquet.

[0046] Third, puncture the patient's femoral artery with the puncture needle. After the puncture is completed, press the puncture point with a tourniquet. At this time, push the rotating rod 8 to move so that the rotating rod 8 is located at the upper end of the puncture point.

[0047] Fourth, the rotating rod 8 is rotated to move the moving cylinder 9 downward and expand the telescopic rod 5. When the arc-shaped extrusion member 7 is close to the puncture point, the medical staff releases the tourniquet and quickly rotates the rotating rod 8 at the same time.

[0048] Fifth, the arc-shaped extrusion member 7 will move downward and press the puncture point through the tourniquet. At this time, sliding will occur between the upper fixed tube 11 and the lower fixed tube 12, causing the support spring 13 to contract. After that, the cylindrical pressure sensor 10 can feel the pressure and the pressure display 14 can display the pressing force, thereby facilitating the control of the pressing force.

[0049] The rotation of the rotating rod 8 will drive the moving tooth plate 19 and the positioning rod 20 to slide through the driving gear 21, and the positioning rod 20 will slide into the interior of the positioning hole 15 and limit the sliding empty plate 4. At the same time, the sliding of the moving tooth plate 19 will drive the moving rod 23 to move through the fixed block 22, and the movement of the moving rod 23 will squeeze the air pressure inside the fixed tube 24 into the interior of the vent tube 25. At this time, the expansion of the gas inside the vent tube 25 will push the limiting rod 26 to move and engage with the limiting hole 16, thereby completing the positioning of the arc extrusion member 7 and ensuring the accuracy of the extrusion of the arc extrusion member 7.

[0050] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, which is convenient for those skilled in the art to understand and apply the present invention. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art of the present invention, several simple deductions or substitutions can be made without departing from the concept of the present invention, without having to go through creative work. Therefore, based on the disclosure of the present invention, simple improvements made to the present invention by those skilled in the art should be within the scope of protection of the present invention.
