Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a hemostasis device after cardiac intervention. Background Art

[0002] Cardiac interventional surgery is a new technology for diagnosing and treating cardiovascular diseases. It is a diagnostic and treatment method that punctures surface blood vessels, inserts a cardiac catheter under continuous digital subtraction imaging, and uses specific cardiac catheterization techniques to diagnose and treat heart disease. It is a relatively advanced method for diagnosing and treating heart disease, and its progress is very rapid. It is between internal medicine treatment and surgical treatment, and is an invasive diagnosis and treatment method. Cardiac interventional treatment wounds are generally entered into the heart through the femoral artery at the groin or the radial artery on the wrist for treatment. After cardiac interventional surgery, patients are generally required to rest in bed, and the puncture point needs to be pressure-bandaged for 24 hours.

[0003] During puncture, if the puncture needle is inserted perpendicularly into the aorta, the projections of the aortic puncture point and the epidermal puncture point in the direction perpendicular to the patient's body surface will coincide. However, in most cases, the puncture needle is inserted at an angle, and the projections of the aortic puncture point and the skin puncture point in the direction perpendicular to the patient's body surface are a certain distance apart. Existing post-cardiac interventional puncture point compression hemostasis devices only apply vertical pressure to the skin puncture point and the surrounding body surface. The pressure on the puncture point and the surrounding muscle tissue is the same, and the compression force cannot be concentrated on the skin puncture point and arterial puncture point that actually need compression. Therefore, the hemostasis effect is poor and the purpose of rapid hemostasis cannot be achieved. Summary of the Invention

[0004] The purpose of the present invention is to provide a post-cardiac intervention hemostasis device to solve the problem that it is difficult to transport wounded patients on medical trains using existing transfer beds due to the narrow curves on the existing medical trains.

[0005] To achieve the above object, the basic scheme of the present invention is as follows:

[0006] A post-cardiac intervention hemostasis device comprises a base plate, a restraining belt arranged on the base plate for fastening the base plate to the patient's limb at the puncture site, a compression mechanism arranged on the base plate for compressing the tissue at the puncture site, an arterial compression mechanism for compressing the arterial puncture point, and an epidermal compression mechanism for compressing the epidermal puncture point.

[0007] In the above scheme, the arterial puncture point and the epidermal puncture point are independently compressed by the arterial compression mechanism and the epidermal compression mechanism respectively, so that the pressure on the artery at the arterial puncture point and the epidermal puncture point is greater than the pressure at other parts, increasing the degree of contraction of the arterial blood vessel at the arterial puncture point, accelerating the closure speed of the arterial blood vessel at the arterial puncture point, and effectively improving the hemostatic effect. Compression on the epidermal puncture point can effectively prevent blood in the microvessels in the muscle tissue from seeping out from the epidermal puncture point, further improving the hemostatic effect.

[0008] Furthermore, the compression mechanism 1 includes a compression block arranged below the substrate and a transmission component 1 arranged on the substrate for driving the compression block to move along the thickness direction of the substrate.

[0009] Furthermore, the transmission component 1 includes an outer cylinder arranged along the thickness of the substrate and an inner cylinder arranged coaxially with the outer cylinder, the lower end of the outer cylinder is rotatably connected to the substrate, the inner wall of the outer cylinder is provided with an internal thread, the outer wall of the inner cylinder is provided with an external thread that cooperates with the internal thread on the inner cylinder, and a through hole 1 is provided on the substrate for accommodating the inner cylinder to pass through, the lower end of the inner cylinder extends into the bottom of the substrate through the through hole 1 and is fixedly connected to the pressure block.

[0010] When the outer cylinder is rotated, the inner cylinder drives the pressing block to move downward to press the skin surface around the puncture point under the cooperation of the threads.

[0011] Furthermore, the arterial compression mechanism includes an inner rod coaxially arranged with the inner tube and an arterial pressure head arranged at the lower end of the inner rod. The outer wall of the inner rod is threadedly connected to the inner wall of the inner tube. The pressure block is provided with two through holes coaxial with the inner tube for accommodating the inner rod and the arterial pressure head to pass through. The upper end of the inner rod extends upward from the inner tube, and the lower end of the inner rod extends downward from the inner tube.

[0012] After rotating the outer cylinder to make the pressure block contact and press the skin surface around the patient's puncture point, the inner rod is then rotated to drive the arterial pressure head downward to press the skin surface at the arterial puncture point, so that the pressure at the arterial puncture point is greater than the pressure at other parts, effectively improving the hemostasis effect.

[0013] Furthermore, the epidermal compression mechanism includes a slide plate arranged on the substrate, a screw arranged along the thickness direction of the substrate and connected to the slide plate through a threaded transmission, and an epidermal pressure head arranged at the lower end of the screw. A through groove 1 is arranged on the substrate along the thickness direction of the substrate, and the length direction of the through groove 1 is parallel to the width direction of the substrate and is arranged along the radial direction of the inner cylinder. A through groove 2 is arranged on the pressure block along the thickness direction of the substrate and is aligned with the through groove 1. The slide plate is located in the through groove 1 and is slidably connected to the substrate. A threaded through hole is provided on the slide plate for cooperating with the screw thread transmission. The screw is passed through the threaded through hole and the epidermal pressure head is located in the through groove 2.

[0014] When the arterial pressure head is aligned with and presses the skin at the arterial puncture point, the slide plate can be slid to align the epidermal pressure head with the epidermal puncture point. After the vascular sheath is pulled out, the screw rod is rotated to lower the epidermal pressure head to press the epidermal puncture point.

[0015] Furthermore, the two inner walls of the through groove 1 that are parallel to the width direction of the substrate are both provided with recessed sliding grooves along the width direction of the substrate, and sliders that slide with the corresponding sliding grooves are respectively provided on both sides of the slide so that the slide can slide along the width direction of the substrate in the through groove 1.

[0016] Furthermore, the restraint belt is a flexible belt and is provided with Velcro.

[0017] Furthermore, the substrate is a hard transparent plate.

[0018] Furthermore, the epidermal pressing head is provided with sterilizing cotton.

[0019] Furthermore, the pressing block is made of transparent silicone.

[0020] Compared with the prior art method of compressing the puncture site as a whole, the present invention has at least the following beneficial effects:

[0021] 1. In this scheme, the arterial puncture point and the epidermal puncture point are independently compressed by the arterial pressure head and the epidermal pressure head respectively, so that the pressure on the artery at the arterial puncture point and the epidermal puncture point is greater than the pressure at other parts, increasing the degree of contraction of the arterial blood vessel at the arterial puncture point, accelerating the closure speed of the arterial blood vessel at the arterial puncture point, and effectively improving the hemostatic effect; the compression of the epidermal pressure head on the epidermal puncture point can effectively prevent the blood in the microvessels in the muscle tissue from seeping out from the epidermal puncture point, further improving the hemostatic effect.

[0022] 2. In this solution, when the arterial pressure head is aligned with the arterial puncture point to press, the epidermal puncture point and the extracorporeal vascular sheath are both located in the second through groove. The pressure block avoids the vascular sheath and does not press on it, making it easy to pull out the vascular sheath and the epidermal puncture point can be wiped and disinfected through the second through groove.

[0023] 3. In this solution, when the arterial pressure head is aligned with and presses the skin at the arterial puncture point, the slide plate can be slid so that the epidermal pressure head is aligned with the epidermal puncture point, which can meet the use of different distances between the arterial puncture point and the epidermal puncture point after puncture at different puncture angles. After puncture at different puncture angles, both can be adjusted to press the arterial puncture point and the epidermal puncture point to improve the hemostatic effect.

[0040] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0042] A post-cardiac intervention hemostasis device according to this embodiment, such as Figures 1-6 As shown, it includes a base plate 10, a restraint belt 20 arranged on the base plate 10 for fastening the base plate 10 to the patient's limb at the puncture site, a compression mechanism arranged on the base plate 10 for compressing the tissue at the puncture site, an arterial compression mechanism for compressing the arterial puncture point 621, and an epidermal compression mechanism for compressing the epidermal puncture point 611.

[0043] The substrate 10 is a "J"-shaped plate comprising a horizontal portion and inclined portions arranged on both sides of the horizontal portion. To facilitate observation of the situation at the puncture point, the substrate 10 is a hard transparent plate, such as a transparent acrylic plate. Both ends of the substrate 10 are connected to flexible straps 20. The straps 20 at both ends of the substrate 10 are equipped with Velcro for conveniently fastening the substrate 10 to the patient's limbs.

[0044] The pressing mechanism 1 includes a pressing block 31 arranged below the horizontal part of the substrate 10 and a transmission assembly 1 arranged on the substrate 10 for driving the pressing block 31 to move along the thickness direction of the substrate 10. The pressing block 31 is a circular block made of transparent silicone. The transmission assembly 1 includes an outer cylinder 321 arranged along the thickness of the horizontal part of the substrate 10 and an inner cylinder 322 arranged coaxially with the outer cylinder 321. The outer cylinder 321 and the inner cylinder 322 are both cylindrical bodies with open ends. The lower end of the outer cylinder 321 is rotatably connected to the substrate 10. The inner wall of the outer cylinder 321 is provided with an internal thread, and the outer wall of the inner cylinder 322 is provided with an external thread that cooperates with the internal thread on the inner cylinder 322. The inner cylinder 322 is threadedly connected to the outer cylinder 321. A through hole 101 is provided on the substrate 10 for accommodating the inner cylinder 322 to pass through. The lower end of the inner cylinder 322 extends into the bottom of the substrate 10 through the through hole 101 and is fixedly connected to the upper surface of the pressing block 31. When the outer cylinder 321 is rotated, the inner cylinder 322 drives the pressing block 31 to move downward to press the surface of the skin 61 around the puncture point under the threaded engagement.

[0045] The arterial compression mechanism includes an inner rod 401 coaxially arranged with the inner cylinder 322 and an arterial pressure head 402 arranged at the lower end of the inner rod 401 for compressing the surface of the skin 61 corresponding to the arterial puncture point 621 on the arterial blood vessel 62. The arterial pressure head 402 is coaxially rotatably connected to the lower end of the inner rod 401. The inner wall of the inner cylinder 322 is provided with an internal thread, and the outer wall of the inner rod 401 is provided with a corresponding external thread so that the outer wall of the inner rod 401 is threadedly connected to the inner wall of the inner cylinder 322. The pressure block 31 is provided with a through hole 311 coaxial with the inner cylinder 322 for accommodating the inner rod 401 and the arterial pressure head 402 to pass through. The upper end of the inner rod 401 extends upward from the inner cylinder 322, and the lower end of the inner rod 401 extends downward from the inner cylinder 322. After the outer cylinder 321 is rotated to make the pressure block 31 contact and press the surface of the skin 61 around the puncture site of the patient, the inner rod 401 is then rotated to make the inner rod 401 drive the arterial pressure head 402 to move downward to press the surface of the skin 61 at the arterial puncture point 621, so that the pressure at the arterial puncture point 621 is greater than the pressure at other parts, thereby effectively improving the hemostatic effect.

[0046] like Figure 2-Figure 5As shown, the epidermal compression mechanism includes a slide plate 501 arranged on the substrate 10, a screw rod 502 arranged along the thickness direction of the substrate 10 and threadedly connected to the slide plate 501, and an epidermal pressing head 503 arranged at the lower end of the screw rod 502. The epidermal pressing head 503 is coaxially connected to the lower end of the screw rod 502 for rotation. A sterilizing cotton is arranged on the epidermal pressing head 503. A through groove 102 is arranged on the horizontal part of the substrate 10 along the thickness direction of the substrate 10, and the length direction of the through groove 102 is parallel to the width direction of the substrate 10 and is arranged along the radial direction of the inner cylinder 322. When the device is used, the width direction of the substrate 10 is consistent with the length direction of the patient's limb, as shown in FIG. Figure 2 、 Figure 4 As shown, the two inner walls of the through groove 102 parallel to the width direction of the substrate 10 are both provided with a groove 103 along the width direction of the substrate 10, and the two sides of the slide plate 501 are respectively provided with sliders 5012 that slide with the corresponding groove 103 so that the slide plate 501 can slide along the width direction of the substrate 10 in the through groove 102. The slide plate 501 is located in the through groove 102 and is slidably connected to the substrate 10. The slide plate 501 is provided with a threaded through hole 5011 that is threadedly driven with the screw 502. Figure 3 、 Figure 5 As shown, the pressing block 31 is provided with a second through-slot 312 aligned with the first through-slot 102 along the thickness direction of the substrate 10. The screw 502 is inserted into the threaded through-hole 5011, positioning the epidermal pressure head 503 within the second through-slot 312. When the arterial pressure head 402 is aligned with and compresses the skin 61 at the arterial puncture point 621, the slide 501 can be slid to align the epidermal pressure head 503 with the epidermal puncture point 611. After the vascular sheath 70 is removed, the screw 502 can be rotated to lower the epidermal pressure head 503 and compress the epidermal puncture point 611.

[0047] When using this solution, according to the patient's body shape and the puncture angle, the pressing block 31 is pressed against the patient's puncture site so that the second through hole 311 corresponds to the arterial puncture point 621. The base plate 10 is fastened to the patient's limb by the binding belt 20. The outer cylinder 321 is rotated to move the pressing block 31 downward to press against the patient's skin 61. Then, the inner rod 401 is rotated to make the arterial pressure head 402 press downward to press the skin 61 at the arterial puncture point 621. The arterial puncture point 621 of the artery 62 is affected. The pressure increases, which speeds up the closing of the artery 62 at the artery puncture point 621. At this time, the vascular sheath 70 is located in the second through groove 312, and the pressure block 31 does not press the vascular sheath 70. The sliding slider 5012 is aligned with the epidermal puncture point 611, and the screw 502 is adjusted to make the epidermal pressure head 503 close to the patient's skin 61. Then, the vascular sheath 70 is pulled out, and the screw 502 is rotated to move the epidermal pressure head 503 downward to press the epidermal puncture point 611 on the skin 61.

[0048] Compared with the prior art method of only compressing the puncture site as a whole, the present invention has at least the following beneficial effects:

[0049] 1. In this solution, the arterial puncture point 621 and the epidermal puncture point 611 are independently compressed by the arterial pressure head 402 and the epidermal pressure head 503, so that the pressure on the artery at the arterial puncture point 621 and the epidermal puncture point 611 is greater than the pressure at other parts, thereby increasing the degree of contraction of the arterial blood vessel 62 at the arterial puncture point 621, accelerating the closure speed of the arterial blood vessel 62 at the arterial puncture point 621, and effectively improving the hemostatic effect; the epidermal pressure head 503 compresses the epidermal puncture point 611, which can effectively prevent the blood in the microvessels in the muscle tissue 63 from seeping out from the epidermal puncture point 611, further improving the hemostatic effect.

[0050] 2. In this solution, when the arterial pressure probe 402 is aligned with the arterial puncture point 621 to press, the epidermal puncture point 611 and the vascular sheath 70 outside the patient's body are both located in the second through groove 312. The pressure block 31 avoids the vascular sheath 70 and does not press the vascular sheath 70, making it convenient to pull out the vascular sheath 70 and the epidermal puncture point 611 can be wiped and disinfected at the second through groove 312.

[0051] 3. In this solution, when the arterial pressure head 402 is aligned with and presses the skin 61 at the arterial puncture point 621, the slide plate 501 can be slid so that the epidermal pressure head 503 is aligned with the epidermal puncture point 611, which can meet the different distances between the arterial puncture point 621 and the epidermal puncture point 611 after puncture at different puncture angles. After puncture at different puncture angles, the arterial puncture point 621 and the epidermal puncture point 611 can be accurately pressed to improve the hemostatic effect.

[0052] The above are only embodiments of the present invention, and the common knowledge such as the specific structure and characteristics of the scheme are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
