Description

Technical Field

[0001] The invention relates to the field of femoral artery puncture arterial hemostasis, and in particular to a wearable femoral artery hemostasis compression device. Background Art

[0002] Clinically, the femoral artery is one of the conventional puncture sites in cardiovascular interventional treatment due to its advantages such as large size, stable shape, significant surface pulsation, and easy positioning. Because the arterial system is under positive pressure, serious complications such as bleeding, subcutaneous hematoma, even pseudoaneurysm, and hemorrhagic shock may occur after puncture treatment. Therefore, effective compression of the puncture point is crucial. The traditional hemostatic compression method is to use gauze bandages to wrap and bandage the puncture point in an "8" shape to achieve the effect of compression and hemostasis on the puncture point. Although this method is relatively mature, it has many defects: 1. After the operation, in order to achieve the "8"-shaped wrapping, the patient needs to raise his hips and change his position several times during the pressure bandage process, which requires the cooperation of multiple medical staff. During the turning process, the puncture point also needs to be pressed by a dedicated person to prevent bleeding. It can be seen that the traditional "8"-shaped wrapping method is very cumbersome. 2. According to the guidelines after interventional surgery, the patient's lower limbs need to be braked for a certain period of time to prevent bleeding or local hematoma caused by loosening or displacement of the pressure bandage material. At the same time, some patients have problems with the compression puncture point due to coma or poor cooperation, which affects postoperative recovery, increases medical safety risks, prolongs the patient's hospitalization time, and reduces patient satisfaction.

[0003] After searching and experiencing other compression and hemostasis products in the medical market, the following disadvantages are generally found: relatively expensive, complex devices, and inability to effectively achieve compression and hemostasis of puncture points in the inguinal ligament area with uneven and irregular anatomical positions.

[0004] Based on this, the inventors designed a new solution that is truly suitable for clinical use based on the actual clinical situation and the shortcomings of existing products. Summary of the invention

[0005] The present invention provides a wearable femoral artery hemostasis compression device. In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A wearable femoral artery hemostasis compression device, comprising a waist belt, a dressing belt and a pressure belt;

[0007] One end of the dressing tape is connected to a waist belt on one side of the human body's waist; the dressing tape is a laminated structure, which includes: an adhesive layer in contact with the skin, a first base layer, and a first bristle layer with exposed Velcro bristles on the surface;

[0008] One end of the pressure belt is connected to the belt on the other side of the human body's waist; the pressure belt is a stacked structure, which includes: a first round hair layer with Velcro round hair on the surface, a second base layer and a second hair layer with Velcro hair on the surface.

[0009] Furthermore, one end of the compress is fixedly connected to a belt on one side of the human waist and / or one end of the pressure belt is fixedly connected to a belt on the other side of the human waist.

[0010] Furthermore, one end of the dressing belt is detachably connected to the waist belt and / or one end of the pressure belt is detachably connected to the waist belt.

[0011] Furthermore, a plurality of first connecting buckles are equidistantly arranged on the belt body, a second connecting buckle is arranged at one end of the dressing belt, and the first connecting buckle and the second connecting buckle are detachably connected; a third connecting buckle is arranged at one end of the pressure belt, and the first connecting buckle and the third connecting buckle are detachably connected.

[0012] Furthermore, anti-slip edges made of elastic material are fixed to the long sides of both sides of the pressure belt.

[0013] Furthermore, the anti-slip edge is gauze with elastic rubber band inside.

[0014] Furthermore, the belt also includes a buckle, which detachably connects the two free ends of the belt.

[0015] Furthermore, the first connecting buckle comprises: a metal threaded hole fixed relative to the surface of the belt body, and a bolt is arranged on the threaded hole; the second connecting buckle and the third connecting buckle are through holes.

[0016] Compared with the prior art, the present invention has the following beneficial effects: compared with the traditional gauze "8"-shaped fixing method, the present invention can provide a mechanically stable three-fold compression force to the puncture point.

[0017] The dressing of the present invention fits the skin completely, and can fit well even the puncture point at the inguinal groove, which is an advantage that other design structures do not have at all.

[0018] The invention innovatively allows the Velcro on the pressure belt to intersect twice, thereby improving the mechanical stability; the pressure belt is allowed to completely follow the contour of the human body, so that the pressure belt and the waist belt form an optimal balancing force solution suitable for different human body contours.

[0019] After the operation, the solution of the present invention only requires one doctor to firmly fix the patient's puncture point. Compared with the traditional "8"-shaped fixation method, which requires many people to turn the patient over, the present invention has great advantages. During the fixation process, it also avoids the need to lift the patient's hips several times and change the patient's position.

[0020] If the patient needs to add pressure to the puncture point during recovery, just open the pressure band, put the thickening pad on the dressing band, and re-secure it with the pressure band. During this process, the puncture point is always under the pressure provided by the dressing band, and there is no need to worry about arterial bleeding. If conditions permit, you can also directly insert the thickening pad between the dressing band and the pressure band, and there is no need to worry about the wound trauma at the puncture point.

[0029] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0030] like Figures 1 to 7 As shown, a wearable femoral artery hemostasis compression device comprises a waist belt 1, a dressing belt 2 and a pressure belt 3. The waist belt 1 is detachably connected via a buckle 11, and the structure of the buckle 11 is a common belt buckle structure or a Velcro structure, or any structure that can fix the two ends of the waist belt 1 to the human body.

[0031] After the belt 1 is fixed to the human body, one end of the dressing belt 2 is connected to the belt 1 on one side of the human waist, such as Figure 7 The dressing 2 is connected to the waist belt 1 on the left side of the human body. The specific connection method can be a fixed connection, such as sewing one end of the dressing 2 and the waist belt 1 into one piece; or a detachable connection. The dressing 2 is a laminated structure, which includes: an adhesive layer 23 in contact with the skin, a first base layer 22, and a first bristle layer 21 with exposed Velcro bristles on the surface. The adhesive material of the adhesive layer 23 can be other medical adhesives such as acrylic glue; the first base layer 22 is an elastic medical fabric, the adhesive layer is close to the skin, and the first bristle layer 21 of the bristle layer is far away from the skin. The three constitute the dressing 2.

[0032] After the belt 1 is fixed to the human body, one end of the pressure belt 3 is connected to the belt 1 on the other side of the human waist. Figure 7 As shown, one end of the pressure belt 3 is fixedly or detachably connected to the waist belt 1 on the right side of the human body. The pressure belt 3 is a laminated structure, which includes: a first round hair layer 34 with Velcro round hair on the surface, a second base layer 33 and a second thorn hair layer 32 with Velcro thorn hair on the surface. The round hair layer of the first round hair layer 34 is facing the skin, and the second base layer 33 is made of non-elastic material. The first round hair layer 34 faces the human skin, and the first round hair layer 34 is used to be detachably fixed with the second thorn hair layer 32.

[0033] like Figure 7 As shown in FIG. 1 , the position of one side of the human waist is: after the belt 1 is fixed, it is on the left side of the human waist; the corresponding other side of the human waist is the right side of the human waist. On the contrary, if the position of one side of the human waist is defined as Figure 7 On the contrary, when the waist belt 1 is fixed, one side of the human body's waist is the right side of the human body, and the other side of the human body's waist is the left side of the human body.

[0034] The compress 2 and the waist belt 1, the pressure belt 3 and the waist belt 1 can be fixedly connected, such as being sewn together or fixed in other ways; or they can be detachably connected, and the specific detachable connection method can be a hook connection, a fixing method with bolts passing through through holes, or the currently common detachable connection method.

[0035] like Figure 1As shown, a plurality of first connecting buckles 12 are provided at equal distances on the belt body of the waist belt 1. The structure of the first connecting buckle 12 is a threaded hole structure with a thread, and a bolt detachably connected to the threaded hole; that is, the bolt or screw is detachably connected to the threaded hole, and the first connecting buckle 12 is composed of the threaded hole and the bolt or screw. A second connecting buckle 20 is provided at one end of the dressing belt 2, and the corresponding second connecting buckle 20 can be a through hole. The bolt passes through the through hole to connect one end of the dressing belt 2 to the waist belt 1, thereby realizing the detachable connection between the first connecting buckle 12 and the second connecting buckle 20. Similarly, a third connecting buckle 30 is provided at one end of the pressure belt 3, and the first connecting buckle 12 and the third connecting buckle 30 are also detachably connected.

[0036] like Figure 7 As shown, in order to prevent the pressure belt 3 from sliding sideways on the human body, an elastic anti-slip edge 31 is fixed on the long sides of the pressure belt 3; the anti-slip edge 31 can be a gauze with elasticity, such as gauze with elastic rubber bands; the anti-slip edge 31 is used to increase the friction between the skin and the pressure belt 3 to prevent sliding. Therefore, the area of ​​the anti-slip edge 31 can be set to be relatively large, and the specific width of a single side can be selected from 1 cm to 5 cm, or even larger than 10 cm.

[0037] by Figures 1 to 7 Taking the structure in the figure as an example, the method of using the present invention is as follows:

[0038] Step 1: When the patient lies on his back on the bed, the doctor passes the belt 1 through the patient's waist and fixes it to the patient's abdomen with a buckle 11.

[0039] Step 2, according to the actual position of the puncture point, connect one end of the dressing tape 2 to the waist belt, open the adhesive layer 23 of the dressing tape 2, and use the adhesive layer 23 to press the pad 5 tightly against the human skin. This can prevent arterial bleeding and also provide a good pressure relief to the puncture point ( Figure 7 After this step, the patient does not need the doctor to take care of the puncture point at all times.

[0040] Step 3, connect the waist belt 1 on the right side of the human body to one end of the pressure belt 3, let the pressure belt 3 pass over the puncture point and go around the thigh, then go out from the inner side of the thigh and press on the puncture point again. In this step, the puncture point is pressed 3 times in total.

[0041] Step 4, the end of the pressure belt 3 is connected to the nearest first connecting buckle 12 on the waist belt 1. When the pressure belt 3 is wrapped, it completely fits the outer contour of the patient's leg, and the final fixing point of the pressure belt 3 can be in the most suitable position to complete the compression of the puncture point. The wrapping of the human leg here is completely based on the different leg shapes of different patients, and can be suitable for the leg shapes of various human bodies.

[0042] The design principle of the present invention is:

[0043] The design of the present invention is based on actual conditions and completely on clinical needs. The connection positions of the dressing band 2, the pressure band 3 and the waist belt 1 can also be adjusted according to actual conditions. For example, in special cases, when the dressing band 2 and the pressure band 3 are connected to the waist belt 1, they may not necessarily be strictly symmetrical at the waist, as long as the pressure band 3 can press the puncture point well according to the patient's body shape. Therefore, the connection position of the end of the pressure band 3 and the waist belt 1 is also completely determined based on the external contour of the human body and the fixed position according to the situation. As long as a stable compressive force can be provided to the puncture point of the human body, especially the puncture point at the inguinal groove 4, the purpose of the present invention is achieved.

[0044] The most important thing is: after the dressing tape 2 uses adhesive to press the pad 5 to the puncture point, the pressure belt 3 is pressed on the puncture point for the first time, and after the pressure belt 3 is wrapped around the thigh, it is pressed on the puncture point for the second time. The intersection and adhesion of Velcro at the puncture point, the anti-slip edge 31, the connection between the first section of the pressure belt 3 and the waist belt 1, and the connection between the end of the pressure belt 3 and the waist belt 1 form a perfect balance force as a whole; in this balance force system, the fixation of the intersection point (puncture point) of the Velcro is equivalent to using the pressure belt 3 to make a loop that completely fits the patient's leg shape. This stable balance force completely solves the drawbacks of the "8" buckle fixing method of the gauze; at the same time, the puncture point finally obtains 3 pressure compressions. If the doctor needs to pressurize the puncture point, a thickened pad can be filled between the dressing tape 2 and the pressure belt 3 at the puncture point to provide greater pressure on the puncture point.
