Be equipped with the external screw thread in buckle 6's cavity boss periphery, adjusting nut 3 is through corresponding internal thread with the spiro union on buckle 6, presses cap 4 to wear to locate T shape briquetting 7 movably from top to bottom outside, and adjusting nut 3's bottom butt is in pressing cap 4, consequently can drive when adjusting nut 3 down the rotating and press cap 4 downstream. Meanwhile, two ends of the elastic piece 5 respectively abut against the bottom plates of the pressure cap 4 and the T-shaped pressing block 7, so that when the pressure cap 4 moves downwards, the elastic piece 5 is compressed, and the axial resetting acting force of the elastic piece 5 can be transmitted to the T-shaped pressing block 7. The compression soft pad 8 is used for contacting with a radial artery puncture part, and the compression soft pad 8 is fixedly connected to the bottom of the T-shaped pressing block 7, or the compression soft pad 8 and the T-shaped pressing block 7 are integrally formed.

Referring to fig. 3, the compression cushion 8 further includes: a mounting surface 81 for attachment to the T-shaped compact, an active surface 82 for contacting the radial artery puncture site, and a plurality of circumferential attachment surfaces 83 for attaching the mounting surface 81 to the active surface 82. The circumferential connecting surface 83 is a circular arc surface structure with a plane transition.

In the process that the compression cushion 8 acts on the puncture part, the smoothly-transited circumferential connecting surface 83 is easy to be attached to the hand of the patient, the indentation is not easy to be left, the indentation does not need to be naturally eliminated after hemostasis is finished, and the rehabilitation experience of the patient is improved; meanwhile, because the bottom action surface 82 of the compression soft cushion 8 is smaller, the skin can be fully compressed by applying smaller pressure at the end of the adjusting nut 3, and the pressure expression effect of the hemostat is better.

Specifically, the four corners of the mounting surface 81 of the pressing pad 8 are smoothly rounded, and the four corners of the acting surface 82 are smoothly rounded. More specifically, the circumferential connection surface 83 in turn comprises: a first connection face 831 and a second connection face 832; the first connecting surface 831 connects the side edge of the mounting surface 81 and the side edge of the acting surface 82 at the same time, and the second connecting surface 832 connects the fillet position of the mounting surface 81 and the fillet position of the acting surface 82 at the same time. Thus, when the pressing pad 8 is applied to the puncture site, no matter the side edge portion or the four corner portions of the circumferential connecting surface 83 is in contact with the skin, the indentation is not easily left.

Specifically, the compression cushion 8 is made of soft and transparent TPR material or silicon rubber material, and can accurately press the puncture part without compressing the ulnar artery, so that the limb of the patient is not required to be fixed, and the pain of the patient is greatly relieved.

Specifically, the utility model discloses a top cap 1, the external screw thread of top cap 1 lock fixed in buckle 6 upper end.

More specifically, the utility model discloses still include that the top of cardboard 2,T shape briquetting 7 is equipped with a top boss 71, the fixed block of cardboard 2 is in the bottom of this top boss 71, and the bottom low pressure of top cap 1 is on cardboard 2, and nut and top and the top of pressing cap 4 are arranged in to cardboard 2. The top cover 1 and the clamping plate 2 are fixed relative to the T-shaped pressing block 7, so that the adjusting nut 3 is prevented from being separated upwards from the pinch plate 6 due to the action of excessive elasticity.

Specifically, the utility model discloses still include elastic cord 9 for tie up patient's hand, and adjust the elasticity. The buckle 6 also comprises a supporting plate 61, the hollow boss is fixed on the supporting plate 61, belt containing holes are formed in two sides of the supporting plate 61, and the elastic bands 9 are annularly tied in the belt containing holes. The elongation of the elastic band 9 is preferably 100% to 300%.

Specifically, a pressure color code is marked on the top end of the T-shaped pressing block 7, and medical staff can qualitatively judge the pressure applying size by observing the position of the pressure color code marked on the upper rod of the pressing cap 4 through the T-shaped pressing block 7, so that the pain or the risk caused by too small pressure applying to a patient is avoided.

The elastic element 5 is preferably embodied as a spring, but other elastic elements known in the art may be used.

Preferably, the buckle 6, the T-shaped pressing block 7 and the compression soft cushion 8 are made of transparent materials, so that medical personnel can directly observe the blood seepage condition of the puncture point.

The working principle of the utility model is as follows:

opening the radial artery hemostasis by compression device, pasting the action surface 82 of the soft compression pad 8 above the puncture point of the radial artery, penetrating the elastic band 9 through the right side of the buckle plate 6 for cerclage, and firmly adhering the elastic band 9 by using a self-adhesive buckle after the elastic band is properly tightened. The adjusting nut 3 is rotated to apply pressure to the radial artery puncture point, the adjusting nut 3 drives the pressing cap 4 to move, so that the elastic part 5 has a compression trend, the axial resetting acting force of the elastic part 5 drives the T-shaped pressing block 7 and the compression soft cushion 8 to apply pressure to the radial artery puncture point, and the hemostasis effect is achieved.

In the process of applying pressure, slowly withdraw from and intervene the medical instrument, intervene medical instrument and withdraw from the back, because buckle 6, T shape briquetting 7, oppression cushion 8 are transparent design, so can the oozing blood condition of direct observation point of puncture, ask the adaptation condition of patient simultaneously, carry out appropriate pressure adjustment through adjusting nut 3. If the puncture point has no blood seepage phenomenon and the patient feels comfortable, the adjusting nut 3 is stopped rotating.

The pressurizing time is 1 to 4 hours according to different puncture pipe diameters; after 4 hours, if no abnormity exists, the adjusting nut 3 can be gradually rotated upwards along the 'withdrawing' direction to reduce the pressure on the puncture point, after 12 hours, the pressurization is released, the radial artery compression hemostasis device is taken down after the existence of the hemorrhage phenomenon on the puncture point is confirmed, and the puncture point is protected by using a sterilized gauze or a sterilized plaster.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art on the basis of the present invention are all within the protection scope of the present invention.
