Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a wound compression hemostatic bandage. Background Art

[0002] Generally, a blood circuit is used in blood purification treatment, such as dialysis treatment. The blood circuit is composed of a flexible tube, which should allow the patient's blood to circulate extracorporeally. The blood circuit includes an arterial blood circuit and a venous blood circuit. An arterial puncture needle for collecting blood from the patient is installed at the front end of the arterial blood circuit, and a venous puncture needle for returning blood to the patient is installed at the front end of the venous blood circuit. A dialyzer is connected between the arterial blood circuit and the venous blood circuit, and a blood pump is provided in the arterial blood circuit. Thus, blood can be circulated extracorporeally while blood purification treatment is performed. After dialysis is completed, the arterial and venous punctures need to be pulled out from the arteries and veins. At this time, medical staff need to use a compression hemostatic bandage to press the puncture sites of the two to stop bleeding. The existing compression hemostatic bandage includes a bandage body, and a sub-velcro and a mother Velcro are provided at both ends of the bandage body. A pressing protrusion is provided in the middle part of the bandage body, and the specific operation of compression and hemostasis is: first, press the puncture site with a cotton ball, and the pressing protrusion corresponds to the cotton ball position, and the bandage body is wrapped around the patient's arm. The strength of the bandage body wrapped around the patient's arm affects the pressure of the pressing protrusion on the cotton ball, and the pressing strength of the cotton ball affects the hemostasis effect. The bandage body is fixed by the sub-Velcro and the mother Velcro. The puncture site is pressed and stopped by the above method, but there are the following problems: due to the different thickness of the patient's arm, the binding strength of the manual bandage body is not accurately grasped, and there will be an over-heavy or over-light squeezing state, which directly affects the hemostasis compression effect; the bandage body will move during the binding process, resulting in the pressing protrusion cannot press the cotton ball well, which will also affect the hemostasis compression effect.

[0031] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0032] Reference Figure 1-12As shown, a wound compression hemostatic bandage described in the utility model comprises a breathable fabric 1, a first breathable adhesive layer 2 fixedly arranged at the lower end of the breathable fabric, a clearance hole 3 arranged in the middle of the breathable fabric, a compression hemostatic member 4 arranged at the clearance hole, a drawstring 5 passing through the two ends of the breathable fabric at both ends respectively, a plurality of straps 6 movably sleeved on the drawstring, a first limiting fabric 7 fixedly arranged on the compression hemostatic member and used for limiting the drawstring, and tightening members 8 respectively arranged at both ends of the drawstring; the tightening member 8 comprises a base 81, a first extension fabric 8 fixedly arranged at both ends of the base, and a second extension fabric 8 fixedly arranged at both ends of the base. The first and second extended fabrics 82 and 83, a second breathable adhesive layer 84 fixedly arranged on the first and second extended fabrics and the base, a reel 85 rotatably arranged on the base, a driving assembly 86 arranged on the reel and the base and used for rotating and fixing the reel, a second position-limiting fabric 87 fixedly arranged on the first extended fabric, a third position-limiting fabric 88 fixedly arranged on the second extended fabric, an annular wire groove 89 arranged on the outer wall of the reel, a first drawstring 810 having one end fixedly arranged in the annular wire groove and the other end fixedly arranged on one end of the drawstring, and one end fixedly arranged on the annular wire groove. The second drawstring 820 is fixed in the shaped wire groove and the other end is fixed on the other end of the drawstring; first, manually press the cotton ball on the puncture site, put the wound compression hemostatic bandage as a whole on the wrist, and press the compression hemostatic piece on the cotton ball, and the breathable fabric is wrapped around the puncture site. The first breathable adhesive layer on the breathable fabric is in contact with the patient's skin, which plays a preliminary fixing effect, avoiding the compression hemostatic piece from moving in the subsequent tightening process of the drawstring, which causes the cotton ball compression position to deviate, and start the tightening piece, which pulls the two ends of the drawstring to move the two ends of the drawstring close to each other, so that The drawstring is tightened to bind the patient. During the tightening process of the drawstring, a force in the direction of the cotton ball is applied to the compression hemostatic component, so that the compression hemostatic component squeezes the cotton ball, and finally compresses the puncture site to stop bleeding. The drawstring can be limited by the first limiting fabric setting to prevent the drawstring from slipping off the compression hemostatic component during the tightening process. The sleeve setting reduces the contact between the drawstring and the patient's skin. During the tightening process of the drawstring, the sleeve contacts the patient's skin, and the sleeve moves relative to the drawstring. In this way, the movement of the drawstring on the patient's skin is greatly reduced during the tightening process, so that the comfort of the drawstring after the binding is completed is improved.The drive assembly drives the reel to rotate, and the reel rotates so that the first drawstring and the second drawstring are wound in the annular wire groove on the reel. The first drawstring and the second drawstring pull the two ends of the drawstring closer to each other respectively. The second breathable adhesive layer has the same effect as the first breathable adhesive layer. The two ends of the drawstring are limited by the second limiting fabric and the third limiting fabric respectively to prevent the drawstring from being separated from the first extension fabric and the second extension fabric. After the tightening force of the drawstring driven by the drive assembly reaches the specified requirement, the drive assembly continues to drive, and the drive assembly slides between the reel. After the drive assembly stops, the reel can be automatically fixed to ensure the binding force of the drawstring, so that the binding force remains consistent. Even if the patient's arm is of different thickness, the binding force of the final drawstring can be ensured to be consistent, and the pressure of the hemostatic component on the cotton ball is consistent, avoiding the puncture site from being squeezed too heavy or too light; the first breathable adhesive layer and the second breathable adhesive layer are replaced accordingly according to the number of uses. ;

[0033] Specifically, the driving assembly 86 includes a rotating seat 861 rotatably arranged on the base, an inner ratchet ring 862 sleeved on the outer side of the rotating seat and fixed on the base, a V-shaped spring piece 863 fixed on the outer wall of the rotating seat and matched with the inner ratchet ring, a plurality of card slots 864 equidistantly distributed on the inner wall of the winding disk, a moving rod 865 movably arranged on the rotating seat, a card block 866 fixed at one end of the moving rod and matched with the card slot, a guide rod 867 fixed on the moving rod, a moving seat 868 movably arranged on the rotating seat and the guide rod at the same time, and a moving seat sleeved on the guide rod and fixed at both ends of the moving seat. and a spring 869 on the moving rod, and a knob 8610 fixed on the rotating seat; the driving assembly 86 also includes a fixed block 8620 fixed on the rotating seat, a first gear slot 8630, a second gear slot 8640 and a third gear slot 8650 provided on the fixed block, an adjustment rod 8660 that passes through and is movably provided on the moving seat, a handle 8670 fixed at one end of the adjustment rod, and a tension spring 8680 sleeved on the adjustment rod and fixed at both ends on the handle and the moving seat respectively; fixed to the base through an inner ratchet ring, and fixed to the rotating seat by a V-shaped spring piece, so that the rotating seat can only rotate in one direction;When the adjusting rod is inserted into the first gear slot, the spring on the moving rod is in a natural expansion and contraction state, at which time the card block is disengaged from the card slot, the winding disk can rotate forwards and backwards, the first drawstring and the second drawstring are in a relaxed state, and when the drawstring needs to be tightened, the handle is moved to move the adjusting rod out of the first gear slot. After the adjusting rod is moved out of the first gear slot, the handle pushes the adjusting rod and the moving seat to move together in the direction of the second gear slot. The spring setting is used to make the moving seat move and push the guide rod and the moving rod to move together, and the card block on the moving rod moves closer to the card slot. , and finally the card block is stuck in the card slot, and the moving seat continues to move to compress the spring. The compressed spring will give a thrust to the moving rod and the card block. When the second gear slot on the moving seat coincides with the adjusting rod, the tension spring setting can generate a thrust to the adjusting rod in the direction of the second gear slot, so that one end of the adjusting rod is inserted into the second gear slot to limit the position of the moving seat. Turn the knob, and the knob drives the rotating seat to rotate. The rotating seat rotates in one direction. The rotation of the rotating seat drives the moving rod, the guide rod, and the moving seat to rotate together, and the card block on the moving rod also rotates together to drive the winding. The reel rotates to reel in the first and second pull ropes, and the two ends of the draw ropes approach each other. When the pulling force on the two ends of the draw ropes reaches the requirement, the rotating seat continues to drive the moving rod and the clamping block to rotate. Since the thrust of the spring on the moving rod and the clamping block is less than the force of tightening the draw rope, the rotation of the rotating seat will not drive the reel to rotate. The reel stops rotating, and the reel slides with the clamping block. At this time, the spring setting can make the moving rod reciprocate on the rotating seat. That is, the reel stops rotating after the tightening force of the draw rope reaches the specified requirement. Even if the rotating seat is continued to be driven to rotate, the reel The rotating seat can only rotate in one direction. After the rotating seat stops rotating, the rotating seat is automatically fixed. At this time, the card block is inserted into the card slot, and the winding disk is fixed by the moving rod and the card block. In special cases, it is necessary to increase the tightening force of the drawstring, move the adjustment rod to the third gear slot, increase the distance the spring is compressed, and increase the thrust of the spring on the moving rod and the card block. Repeating the above work can increase the tightening force of the drawstring; when the squeezing of the cotton ball is completely relaxed, the adjustment rod is moved to the first gear slot. ;

[0034] Specifically, the compression hemostatic component 4 includes a rubber box 41 arranged in the yield hole, a cotton ball cavity 42 arranged on the rubber box, a rubber anti-slip ring 43 fixedly arranged at the lower end of the rubber box, and an arc ring 44 fixedly arranged on the rubber anti-slip ring; the first limiting fabric is fixed on the rubber box; the cotton ball cavity is set to enable the cotton ball to be located therein, thereby avoiding misalignment of the cotton ball and the rubber box, and ultimately avoiding the cotton ball from moving and affecting the compression effect. During the tightening process of the drawstring, a pressure will be applied to the rubber box, and ultimately pressure will be applied to the cotton ball. The arc ring setting can increase the contact area between the rubber box and the patient's skin, thereby making the rubber box less likely to move. The rubber anti-slip ring setting can enable a snap connection between the cotton ball and the rubber box, which is equivalent to a fixed connection between the cotton ball and the rubber box.

[0035] Specifically, the compression hemostatic component 4 also includes an upper rubber ring 45 fixedly mounted on the outer wall of the rubber box, a lower rubber ring 46 located below the upper rubber ring and fixed in the make way hole, and a reset airbag 47 with two ends respectively fixed on the upper rubber ring and the lower rubber ring; through the setting of the reset airbag, the rubber box can be reset after the compression is stopped in the later stage, and the overall setting of the above-mentioned compression hemostatic component can improve the comfort during the compression process.

[0036] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the utility model involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned utility model concept.
