Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a femoral artery compression hemostasis device. Background Art

[0002] With the promotion of interventional technology, the femoral artery has become a common channel for interventional surgery. However, after the interventional surgery, hemostasis at the femoral artery puncture site is still a prominent problem. Common femoral artery hemostasis methods include: artificial compression hemostasis and mechanical compression hemostasis. The disadvantages of the above femoral artery hemostasis methods are: the artificial compression hemostasis method usually uses a salt bag to compress and fix the patient's femoral artery puncture point. In this compression hemostasis method, the compression force is not easy to control, and the unstable pressure leads to poor hemostasis effect; the mechanical compression hemostasis method mainly compresses the femoral artery puncture site from outside the body through mechanical compression force to promote hemostasis and healing of the puncture site. When the existing femoral artery mechanical hemostat is in use, it is usually fixed to the required position with a strap for compression hemostasis. However, the mechanical compression hemostasis devices currently used in clinical practice are mostly adjusted by thread adjustment to adjust the compression force. When in use, it is necessary to twist it significantly to adjust the compression force to the applicable range; therefore, there is the problem of inconvenient operation, so there are problems of excessive compression caused by excessive twisting and loose compression caused by insufficient twisting range.

[0017] Figure 1 —6 shows the main technical content of this embodiment. This specific embodiment provides a femoral artery compression hemostasis device, which includes: The main body 1 has a receiving cavity 11, wherein the receiving cavity 11 has a first position 112 and a second position 113 in the depth direction of the receiving cavity 11, wherein the first position 112 is located above the second position 113 in the depth direction of the receiving cavity 11; A pressure member 2 is slidably connected to the main member 1, wherein a portion of the pressure member 2 is located in the accommodating cavity 11; An adjusting mechanism, the adjusting mechanism comprising a driving part, the driving part is rotatably connected to the main body 1, and the driving part partially extends into the accommodating cavity 11, wherein the driving part has a first axis, and the driving part can rotate relative to the main body 1 with the first axis as a reference; and The transmission part is disposed in the accommodating chamber 11 and is rotatably connected to the driving part and the pressure member 2. When the driving part rotates, the transmission part moves between the first position 112 and the second position 113 in the accommodating chamber 11 to drive the pressure member 2 to move in the extension direction of the first axis.

[0018] When in use, the main body 1 is placed at the femoral artery puncture point of the patient, and the pressure piece 2 is pressed on the femoral artery puncture point of the patient. Then, by rotating the driving member, the transmission part is switched between the first position 112 and the second position 113 in the accommodating chamber 11, so that the pressure piece 2 moves in the extension direction of the first axis, and then presses on the femoral artery puncture point of the patient, thereby performing compression hemostasis.

[0019] refer to Figure 1 —2. In the present embodiment, it also includes: a fixing belt, wherein the fixing belt includes: a first fixing belt and a second fixing belt, wherein the first fixing belt and the second fixing belt are both connected to the main body 1, and the first fixing belt and the second fixing belt are detachably connected. When in use, the main body 1 is placed at the femoral artery puncture point of the patient, and the pressure-applying member 2 is pressed on the femoral artery puncture point of the patient, and then the first fixing belt and the second fixing belt are connected after being wrapped around the patient's thigh, so that the main body 1 is fixed at the root of the patient's thigh, so as to avoid displacement of the main body 1 during use.

[0020] More specifically, the outer wall of the main body 1 has a first connection portion and a second connection portion that are mirror images of each other, wherein one end of the first fixing belt is connected to the first connection portion, and one end of the second fixing belt is connected to the second connection portion. When in use, the main body 1 is first placed at the femoral artery puncture point of the patient, and the pressure piece 2 is pressed against the femoral artery puncture point of the patient, and then the first fixing belt and the second fixing belt are connected around the patient's thigh along the direction of the patient's groin extension, so that the main body 1 and the pressure piece 2 always correspond to the femoral artery puncture position of the patient.

[0021] In this embodiment, the first fixing strap has a first outer surface, and the second fixing strap has a first inner surface, wherein a Velcro fleece surface is provided on the first outer surface, and a Velcro hook surface is provided on the first inner surface. When in use, the Velcro fleece surface on the first fixing strap is fit with the Velcro hook surface on the second surface, so that the first fixing strap and the second fixing strap are connected to fix the main body 1 at the femoral artery puncture point of the patient.

[0022] Alternatively, a plurality of sub-buckles are provided on the first outer surface, and one or more female buckles are provided on the first inner surface. When in use, the female buckle and the sub-buckle are fastened together, so that the first fixing belt and the second fixing belt are connected. In addition, with the provision of a plurality of sub-buckles, the fixing strength of the first fixing belt and the second fixing belt to the main body 1 can be adjusted according to the patient's leg circumference when in use.

[0023] refer to Figure 1 —3. Preferably, it also includes: a third fixing belt, which is detachably connected to the first fixing belt, wherein the outer wall of the main body 1 also has a third connecting portion 14. In this embodiment, the first connecting portion, the second connecting portion and the third connecting portion 14 are circumferentially distributed on the outer wall of the main body 1 around the first axis, and the distance between the second connecting portion and the first connecting portion is the same as the distance between the third connecting portion 14 and the first connecting portion, and the distance between the second connecting portion and the third connecting portion 14 is smaller than the distance between the first connecting portion and the second connecting portion. When in use, the first fixing belt corresponds to the patient's groin position, and the second fixing belt and the third fixing belt are located on the outside of the patient's thigh. Under this setting, the first fixing belt, the second fixing belt and the third fixing belt are in a crossed state, and the main body 1 is located at the intersection of the three fixing belts, thereby further improving the fixing strength of the main body 1.

[0024] refer to Figure 2 —4. In this embodiment, the main body 1 includes: a first mounting portion 15 and a second mounting portion 16, wherein the second mounting portion 16 is arranged at one end of the first mounting portion 15, wherein the accommodating cavity 11 is opened from the other end of the first mounting portion 15 toward the second mounting portion 16 and penetrates the second mounting portion 16, and the diameter of the first mounting portion 15 is greater than the diameter of the second mounting portion 16.

[0025] refer to Figure 3 —5. In the present embodiment, the accommodating cavity 11 has an inclined bottom surface 111, and the first position 112 and the second position 113 are both located on the inclined bottom surface 111, wherein the transmission part is partially in contact with the inclined bottom surface 111, and when the driving part rotates, the transmission part moves between the first position 112 and the second position 113 on the inclined bottom surface 111; more specifically, the inclined bottom surface 111 is formed in the first mounting portion 15, and when the driving portion rotates, the transmission part rotates synchronously with the driving portion. At this time, under the action of the inclined bottom surface 111, the spatial posture of the transmission part in the accommodating cavity 11 changes, and acts on the pressure member 2, so that the pressure member 2 is away from the second mounting portion 16 or close to the second mounting portion 16 in the extension direction of the first axis. When in specific use, after the main body 1 is fixed to the femoral artery puncture point of the patient by the first fixing belt and the second fixing belt, the driving portion is rotated so that the pressure member 2 compresses the femoral artery puncture point of the patient, thereby compressing and stopping bleeding for the patient.

[0026] More specifically, the cross section of the accommodating cavity 11 is circular.

[0027] refer to Figure 4 —6. In this embodiment, the transmission part includes: a transmission rod 4 and a connecting rod 5. The transmission rod 4 is rotatably connected to the driving part. The outer wall of the transmission rod 4 is tangential to the inclined bottom surface 111, and the axis of the transmission rod 4 is parallel to the inclined bottom surface 111; one end of the connecting rod 5 is rotatably connected to one end of the transmission rod 4, and the other end of the connecting rod 5 is rotatably connected to the pressure member 2; wherein, when the driving part rotates, one end of the transmission rod 4 rotates circumferentially around the first axis, and moves toward the pressure member 2 under the action of the inclined bottom surface 111, so that the connecting rod 5 The rod 5 pushes the pressure piece 2 to move in the extension direction of the first axis. When in use, after the main body 1 is fixed to the femoral artery puncture point of the patient by the first fixing belt and the second fixing belt, the driving part is rotated. At this time, the transmission rod 4 rotates synchronously with the driving part, and under the action of the inclined bottom surface 111, it rotates radially relative to the first axis, so that the distance between the two ends of the transmission rod 4 and the second mounting part 16 changes step by step, thereby allowing the connecting rod 5 to push the pressure piece 2 to apply pressure to the femoral artery puncture point of the patient or reduce the pressure.

[0028] refer to Figure 5 and Fig. 9 —10, more specifically, the transmission rod 4 has a first end 41 and a second end 42, wherein the driving portion is connected between the first end 41 and the second end 42, and the connecting rod 5 is connected to the first end 41; more specifically, the connecting rod 5 has a first connecting end and a second connecting end, wherein the first connecting end of the connecting rod 5 is pivotally connected / histogrammed to the first end 41 of the transmission rod 4, and the second connecting end of the connecting rod 5 is pivotally connected / histogrammed to the pressure member 2, and when the first end 41 of the transmission rod 4 moves on the inclined bottom surface 111, the first connecting end of the connecting rod 5 rotates relative to the first end 41 of the transmission rod 4, so that the second connecting end of the connecting rod 5 approaches / moves away from the transmission rod 4, thereby driving the pressure member 2 to move in the length extension direction of the first axis; and the driving portion is connected between the first end 41 and the second end 42, which can also keep the outer wall of the transmission rod 4 tangent to the inclined bottom surface 111.

[0029] Specifically, the cross-section of the transmission rod 4 is circular. Under this setting, the transmission rod 4 always maintains a close fit with the inclined bottom surface 111, thereby preventing the transmission rod 4 from moving due to the reaction force after the pressure piece 2 is pressed on the patient's body surface, thereby ensuring that the force applied by the pressure piece 2 remains unchanged during use.

[0030] Preferably, the first end 41 and the second end 42 of the transmission rod 4 are also provided with pulleys. When the driving member rotates, the pulley at the first end 41 and the pulley at the second end 42 rotate, thereby facilitating the transmission rod 4 to rotate with the driving part.

[0031] refer to Figure 5 —7 and Fig. 9 —10. In addition, when the first end 41 moves from the first position 112 to the second position 113, the pressure member 2 gradually moves away from the transmission rod 4 in the extension direction of the first axis, so that pressure is applied to the femoral artery puncture point of the patient. Conversely, when the first end 41 moves from the second position 113 to the first position 112, the pressure member 2 gradually moves toward the transmission rod 4 in the extension direction of the first axis, so that the pressure applied by the pressure member 2 to the femoral artery puncture point of the patient is reduced. Therefore, when in use, according to the condition of the patient's puncture point, the position of the first end 41 of the transmission rod 4 is moved between the first position 112 and the second position 113 by rotating the driving part, so that the pressure of the pressure member 2 on the puncture point is adjusted to an applicable force, thereby ensuring that the patient's blood circulation is not affected during the compression hemostasis process, and avoiding instrumental skin damage and blisters.

[0032] refer to Figure 2 and Figure 5 —7, in this embodiment, the driving part includes: a rotating member 6 and a transmission shaft 7, wherein the rotating member 6 is rotatably connected to the main body 1, wherein the rotating member 6 is constructed to be able to rotate relative to the main body 1; one end of the transmission shaft 7 is fixedly connected to the rotating member 6, and the other end of the transmission shaft 7 extends into the accommodating chamber 11 and is connected to the transmission rod 4; wherein, when the rotating member 6 rotates, the transmission shaft 7 rotates synchronously with the rotating member 6; more specifically, the accommodating chamber 11 includes: a first accommodating chamber and a second accommodating chamber, wherein the first accommodating chamber is opened in the first mounting portion 15, the second accommodating chamber is opened in the second mounting portion 16, and the first accommodating chamber is opened in the second mounting portion 16. A accommodating cavity is communicated with a second accommodating cavity, wherein the rotating member 6 is installed on the second mounting portion 16, and the rotating shaft is arranged in the second accommodating cavity, and one end of the transmission shaft 7 extends out from the second accommodating cavity, and the other end of the transmission shaft 7 extends into the accommodating cavity 11, and the transmission shaft 7 and the rotating member 6 are integrally formed, or a connecting hole is opened on the rotating member 6, and a first key groove is opened on the inner wall of the connecting hole, and a second key groove is opened on the outer wall of the transmission shaft 7, wherein the transmission shaft 7 is inserted into the connecting hole, and flat keys are assembled in the first key groove and the second key groove, so that when force is applied to the rotating member 6, the transmission shaft 7 can rotate synchronously with the rotating member 6.

[0033] refer to Figure 5—8. As can be understood by those skilled in the art, when the rotating member 6 rotates in the same direction, the first end portion 41 of the transmission rod 4 moves to the second position 113 after passing the first position 112. During this process, the pressure member 2 is first pushed out of the accommodating chamber 11 by the connecting rod 5, and then driven by the connecting rod 5 to move into the accommodating chamber 11. Through this arrangement, the pressure can be adjusted slightly when the pressure is adjusted, so as to more accurately apply pressure to the femoral artery puncture point and avoid excessive pressure on the femoral artery puncture point.

[0034] refer to Figure 5 —7 and 9—10, in this embodiment, the end of the transmission shaft 7 extending into the accommodating cavity 11 is provided with: a first arm 71 and a second arm 72 which are mirror-symmetrical to each other, wherein the first arm 71 and the second arm 72 are both provided with a connecting shaft, the axis of the connecting shaft is perpendicular to the first axis, and the transmission rod 4 is provided with a through hole, and the connecting shaft penetrates into the through hole, wherein, when the transmission shaft 7 rotates, the transmission rod 4 rotates axially around the first axis with the transmission shaft 7, and the transmission rod 4 rotates circumferentially around the axis of the connecting shaft under the action of the inclined bottom surface 111, so that the first end 41 moves from the first position 112 to the second position 113, for example, When the first end 41 is located at the first position 112, the rotating member 6 rotates, and at this time, the transmission rod 4 rotates accordingly. The first end 41 of the transmission rod 4 rises in a spiral manner in the accommodating cavity 11 under the action of the inclined bottom surface 111 until the first end 41 reaches the second position 113. Conversely, when the first end 41 moves from the second position 113 to the first position 112, the first end 41 of the transmission rod 4 descends in a spiral manner in the accommodating cavity 11 under the action of the inclined bottom surface 111. In addition, during this process, the second connecting end of the connecting rod 5 moves in the same manner as the first end 41, thereby driving the pressure member 2 to move.

[0035] refer to Figure 5 —6 and Fig. 9In the present embodiment, the pressure member 2 comprises: a sliding portion 21 and a pressing plate 22, the sliding portion 21 having a first end and a second end, the first end being located in the accommodating chamber 11 and connected to the transmission portion, and the second end extending out of the accommodating chamber 11, wherein the transmission portion is hinged to the first end, and the pressing plate 22 is arranged at the second end of the sliding portion 21, wherein the pressing plate 22 is fixedly connected to the sliding portion 21; more specifically, the sliding portion 21 is constructed so as not to completely escape from the accommodating chamber 11, so that when the first end portion 41 of the transmission rod 4 is located at the first position 112, at least a portion of the sliding portion 21 is still located in the accommodating chamber 11, so that the accommodating chamber 11 maintains the constraint on the sliding portion 21 in the radial direction of the first axis; when in use, the pressing plate 22 is in contact with the patient's body surface, and when the rotating member 6 is rotated, the sliding portion 21 moves in the accommodating chamber 11, so that the pressing plate 22 applies force to the patient's femoral artery puncture point, thereby performing compression and hemostasis.

[0036] More specifically, a sterile pad is provided on the side of the pressing plate 22 away from the sliding portion 21, wherein the sterile pad is connected to the pressing plate 22 by gluing. When in use, the sterile pad is fitted with the femoral artery puncture point of the patient. At this time, the sterile pad can deform along with the curved surface of the patient's body surface, so that the pressing plate 22 is more fitted with the patient's groin position, thereby making the force on the femoral artery puncture point of the patient uniform; preferably, the sterile pad can be separated from the pressing plate 22, so that after compression and hemostasis for the patient, the device can be used again, thereby saving the patient's medical costs.

[0037] Method of use of the present invention: 1. When in use, place the main body at the femoral artery puncture point of the patient, and make the pressure-applying member press on the femoral artery puncture point of the patient, and then fix the main body with the first fixing belt, the second fixing belt and the third fixing belt; 2. Rotate the rotating member so that the first end of the transmission rod moves to the first position in the accommodating cavity, so that the pressure-applying member gradually applies pressure to the puncture point of the femoral artery of the patient. When the pressure is insufficient, continue to rotate the rotating member until the pressure is adjusted to the appropriate force; 3. After compression and hemostasis are completed, the third fixing belt and the second fixing belt are separated from the first fixing belt. At this time, the main body loses the constraints of the first fixing belt, the second fixing belt and the third fixing belt, so the device can be removed.

[0038] The above embodiments are only used to understand the present invention. It should be noted that, for those skilled in the art, several improvements can be made to the present invention without departing from the principles of the present invention, and these improvements will also fall within the scope of protection of the claims of the present invention.
