Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a hand-imitating hemostatic clamp. BACKGROUND

[0002] Coronary angiography is the standard for diagnosing coronary heart disease, and radial artery puncture is the preferred path for percutaneous coronary intervention. Intervention often accompanies complications such as postoperative bleeding, puncture site hematoma, radial artery occlusion and pressure injury, etc. Therefore, it is of great significance to explore better hemostatic measures for patients undergoing intervention. After observing and analyzing the mechanical structure of the hand, doctors found that the hand has a natural advantage in pressing the radial artery for hemostasis. The biggest problem of using the hand to press the radial artery for hemostasis is that it is difficult to overcome fatigue and maintain continuous stable pressing for several hours. Therefore, various types of hemostatic clamps or hemostatic bands are commonly designed on the market.

[0003] The application announcement number CN113171151A discloses a radial artery hemostatic compression band assembly with pressure indication. According to the specification and drawings, the scheme is to align the center point of the elastic body with the puncture point, and pass the fixing band around the limb and through the hanging buckle connected with the fixed plate, tighten and lock, adjust the tightening force of the fixing band according to the patient's body type, use magic tape to stick, twist the rotating cap, and with the rotation of the rotating cap, the spiral rod drives the elastic body to continuously press down on the patient's puncture point. The elastic body compresses the radial artery puncture point, the indicating ring moves inside the rotating cap to indicate the pressure scale, and the pressure value is displayed. The medical staff adjusts the compression force by rotating the rotating cap clockwise or counterclockwise according to the pressure scale indication. However, this scheme has defects. The threads of the spiral rod are prone to automatic loosening during use, causing bleeding. The hanging buckle, as a supporting part, tightly wraps around most of the area on the opposite side of the pressing site, compressing the dorsal venous network, causing poor blood flow in the local area of the patient and causing swelling and discomfort. When the puncture point is low, the fixing band of the hemostatic device compresses the ulnar process or the process, which increases the local swelling and pain of the patient, and reduces the patient's comfort and satisfaction. Long-term use and high pressure often cause pain, swelling, numbness, and pressure injury in the patient's puncture side, leading to the patient's refusal to continue using the device, thereby affecting the hemostatic and therapeutic effect.

[0024] The support assembly 5 comprises a plurality of support columns 51, the surface of the second clamping piece 2 is provided with a plurality of through grooves 23, the inside of each through groove 23 is slidably connected with a plurality of support columns 51, the adjacent support columns 51 do not interfere with each other, the end of the support column 51 is provided with a column boss 511, the column boss 511 is inserted into the inside of the through groove 23, the cross-sectional area of the support column 51 is larger than that of the column boss 511, the inside of the support column 51 is towards the second clamping piece 2, the column boss 511 is towards the outside of the second clamping piece 2, the surface between a plurality of support columns 51 in the same through groove 23 forms a support plane 52, a plurality of support planes 52 and the pressing shell 41 form the clamping area 3, the hemostat is stable and does not move, the number of through grooves 23 is 4, and there are 3 support columns 51 in each through groove 23, after such setting, first, the air bag 42 is inflated by using the inflation valve 44, since the pressing shell 41 and the air bag 42 are fixedly connected, when the air bag 42 expands, it will push the pressing shell 41 to move outward, then the inside of the first clamping piece 1 and the second clamping piece 2 is attached to the wrist, and the pressing shell 41 is attached to the bleeding point, the doctor adjusts and fixes by winding the rope through the fixed hook 6 with the other hand, and adjusts and fixes by observing the reading of the pressure indicator 46 with the eyes, the arterial compression point of the upper pressing shell 41, and the 3 support columns 51 on each through groove 23 below, a total of 12 support points, since the total value of the upper and lower pressures is equal, the pressure received by each support point below is only one twelfth of the pressure of the arterial hemostatic point, which will not block the blood return of other areas of the wrist, of course, if the number of through grooves 23 and the number of support columns 51 are increased, the number of support points of the support columns 51 below can also be more, effectively dispersing the stress condition, but the pressure of the compression point at the bottom of the pressing shell 41 must be greater than or equal to the systolic pressure of the radial artery, and the pressure of each support point on the surface of the support column 51 is preferably less than the blood pressure of the subcutaneous vein, in order to prevent the support points on the surface of the support column 51 from being stressed for too long and causing blood stasis in the wrist area, the support column 51 can slide along the through groove 23 after supporting for a period of time.

[0025] In the first embodiment, in order to explain the whole hemostatic clamp can have the effect of finger pressing, wherein the right end of the first clamp 1 and the second clamp 2 is fixed, the bottom of the pressing shell 41 on the first clamp 1 is equivalent to the thumb pressing the hemostatic mouth, and the four through grooves 23 are equivalent to the four knuckles of the fingers, and the surface of the 12 movable support column bodies 51 inside the through groove 23 is equivalent to the support point of the fingers adhering to the wrist, and the surface between the three support column bodies 51 inside the same through groove 23 forms a support plane 52 that is not in a straight line. The pressing point of the upper pressing shell 41 and the support point of the plurality of support column bodies 51 on the lower support plane 52 jointly constitute a three-dimensional stable compression support positioning space, i.e. the clamping area 3, so that the hemostatic clamp is stable and does not move, and since the four fingers can be rotated and rested in daily life, each support column body 51 can be appropriately moved and adjusted to slide inside the through groove 23, so that the whole hemostatic structure is equivalent to imitating a hand to press the hemostatic.

[0026] In the first embodiment, the materials of the pressing shell 41, the support shell 411 and the air bag 42 are transparent, which is to enable the doctor or nurse to directly observe the real-time state of the bleeding point through the pressing shell 41. The material of the support column body 51 is soft plastic, which is to reduce the pressure effect of the surface of the support column body 51 on the wrist and optimize the comfort of the patient when wearing.

[0027] In the second embodiment, as Figure 5 Unlike the first embodiment, the first clamp 1 and the second clamp 2 are made of slightly deformable flexible material, such as elastic silicone material, and the inside of the column shaft 22 is provided with a torsion spring, which is connected to the shaft support column 11 through the torsion spring, so that it has a certain locking force. The shaft support column 11 is fixedly connected to one end of the first clamp 1. In order to make the structure clearer, the second clamp 2 is disassembled in the figure. One end of the second clamp 2 is provided with two fixed hooks 6. The external rope is tied to one hook 6 on the first clamp 1 and two hooks 6 on the second clamp 2 to form a stable triangular fixing structure, so that the whole device is not easy to slide when hemostasis.

[0028] For the first embodiment or the second embodiment of the hand-imitating hemostatic clamp, it is superior to the current various radial artery hemostasis devices in the flexibility of human hands. By observing and analyzing the mechanical structure of the hand, it can be seen that the hand is a top version of the hemostatic clamp, the thumb pad presses the hemostasis, and the remaining 4 fingers, a total of 12 segments of the knuckles, serve as support points on the opposite side of the pressing point. On the one hand, the number of pressing points: the number of support points = 1:12, if the area of the pressing point = the area of each support point, then the pressure of each support point = 1 / 12 of the pressure of the pressing point, and the support point of the patient's dorsal vein bears less pressure. On the other hand, the 12 support points are discontinuously distributed on the dorsal side of the hand opposite the pressing point, and do not cause the large area of the vein to be blocked by pressure, and still can ensure the unobstructed blood flow of the dorsal vein. Based on such characteristics, a special hemostatic clamp is designed to imitate the structure of the hand. The upper clamp of the clamp, that is, the first clamping part 1, is designed to be similar to the structure of the thumb to realize the function of pressing hemostasis. The lower clamp of the clamp, that is, the second clamping part 2, is designed to be similar to the structure of the other four fingers by using the support assembly to realize the function of dispersed multiple point support. The precision of the hand is well combined with the stability and durability of the device, which provides a design idea for the hand-imitating hemostatic clamp.

[0029] The working principle and use method of the present application are as follows:

[0030] Step 1: inflate the air bag 42 so that the air pressure generated by the air bag 42 is greater than or equal to the arterial blood pressure;

[0031] Step 2: the doctor uses one hand to clamp the clamp formed by the first clamping part 1 and the second clamping part 2 on the patient's wrist;

[0032] Step 3: the doctor uses the other hand to wind the rope while fixing the hook 6, and adjusts the fixing while observing the reading of the pressure indicating table 46 with the eyes;

[0033] Step 4: after a period of compression, it is necessary to loosen for a period of time, open the pressure relief device 45 at the end of the inflation valve 44 to reduce the pressure, and observe the reading of the pressure indicating table 46 at the same time;

[0034] Step 5: observe whether there is bleeding at the bleeding point through the transparent pressing shell 41, and then re-press the bleeding point.

[0035] Step 6: the bleeding point is healed, and the rope on the fixing hook 6 is untied.

[0036] The specific embodiments described in the present application are only illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, without deviating from the spirit of the present application or exceeding the scope defined by the appended claims.
