Description

Technical Field

[0001] This invention belongs to the field of medical auxiliary device technology, specifically referring to a device for hemostasis by compression at the puncture site after cardiac intervention and its usage method. Background Technology

[0002] Cardiac interventional surgery dates back to the 1950s. Due to its advantages such as minimal invasiveness, rapid recovery, and high postoperative quality, it has become a common treatment method. Compared with traditional femoral artery puncture, the radial artery puncture method via the wrist has shown significant advantages in terms of complication rate, patient comfort, and post-discharge rehabilitation, and has now become the mainstream clinical choice.

[0003] Postoperative bleeding from the puncture site is a common complication, potentially leading to hematoma, pheochromocytoma, infection, and other problems. Therefore, it is essential to apply sufficient pressure to the puncture site to achieve hemostasis, effectively shorten the hemostasis time, improve work efficiency, and accelerate the patient's recovery. Postoperative hemostasis typically requires 12 to 24 hours of continuous pressure.

[0004] While existing compression hemostasis devices employ some techniques targeting the puncture site, several problems remain. First, because continuous pressure must be applied to the puncture site for 12 to 24 hours, patients often find it difficult to perform normal daily activities, including simple arm movements. Second, if the forearm remains horizontally downwards for an extended period due to accidental movement, lack of attention during sleep, or muscle fatigue, blood return may be obstructed, leading to swelling, pain, and even severe myocardial ischemia. Furthermore, wrist edema may cause nerve damage, resulting in limited sensation or movement in the arm. Finally, prolonged exertion to keep the arm upright can cause fatigue and soreness in the arm, hindering recovery. Existing hemostasis devices do not provide an effective solution to these problems.

[0005] Therefore, there is an urgent need to invent a new type of device for compression hemostasis at the puncture site after cardiac interventional procedures in order to better solve this problem. Summary of the Invention

[0006] In response to the above situation, the present invention provides a puncture point compression hemostasis device and its usage method after cardiac intervention. It can provide continuous, stable and effective compression to the puncture point while providing stable upward support to the forearm and allowing for simple and independent adjustment of the arm angle. This prevents swelling of the arm caused by the forearm being horizontally downward due to various accidents and fatigue and discomfort caused by maintaining an upward posture.

[0007] The technical solution adopted by this invention is as follows: This invention proposes a puncture point compression hemostasis device after cardiac intervention, including a protective shell. The protective shell is symmetrically arranged on both sides of the elbow joint. The protective shell is a hollow cylinder with one side semi-circular wall open. An upper arm support rod is inserted through one side of the protective shell at the opening, and a lower arm support rod is inserted through the other side of the protective shell at the opening. An upper arm wrapping strap is fixed on the upper arm support rod. A lower arm support strap is provided in the middle of the lower arm support rod. A compression hemostasis airbag is provided near the end of the lower arm support rod. A hand back support strap is provided at the end of the lower arm support rod. A press release mechanism is provided at one end of the lower arm support rod. A gravity adjustment support mechanism is provided inside the protective shell.

[0008] Furthermore, the gravity adjustment support mechanism includes a rotating disk. The rotating disk is concentrically arranged and axially fixed with the protective shell, one end of the lower arm support rod, and one end of the upper arm support rod. The edge of the rotating disk has a convex ring on the closed side of the protective shell, and the edge of the rotating disk has multiple grooves arranged in a circular array along the center within a quarter circle of the open side of the protective shell, thereby achieving a positioning function.

[0009] Furthermore, a gravity cavity is fixedly provided on the upper arm support rod at a position inside the protective shell, a first spring is fixedly provided inside the gravity cavity, and a gravity block is fixedly provided at one end of the first spring, with the gravity block located between the two sides of the rotating disk.

[0010] Furthermore, the lower arm support rod has a hollow structure, and an inner lower arm insert rod is inserted inside the lower arm support rod. A locking block is fixed at one end of the inner lower arm insert rod located inside the protective shell. The locking block passes through the lower arm support rod. A second spring is fixed at the other end of the inner lower arm insert rod, and one end of the second spring is fixedly connected to the inner side of one end of the lower arm support rod.

[0011] Furthermore, the press-release mechanism includes a fixed rod, one end of which is fixedly connected to one end of the lower arm support rod, and the other end of which is fixedly provided with a pressing cavity. The pressing cavity is a hollow cavity with one open end. A slide is fixedly provided on the inner surface of the closed end of the pressing cavity. The slide is provided with a vertical through hole and a horizontal through hole. A pressing button is inserted tightly into the open end of the pressing cavity. The pressing button is a hollow cavity with one open end. A third spring is fixedly provided at the center of the inner surface of the closed end of the pressing button. A vertical reciprocating rod is fixedly provided at one end of the third spring. Two inclined sliders are fixedly provided on the inner surface of the side wall of the pressing button. The two inclined sliders are centrally symmetrical.

[0012] Furthermore, the pressing release mechanism includes an irregularly shaped slider, which is inserted tightly into the horizontal through hole, allowing the slider to move only horizontally. The inclined surfaces on both sides of the irregularly shaped slider connect with the inclined surfaces of the inclined slider, and the inclined surface in the middle of the irregularly shaped slider is tightly attached to and penetrates the vertical reciprocating rod. The vertical reciprocating rod is inserted into the vertical through hole and penetrates the lower wall of the pressing cavity. One end of the vertical reciprocating rod is fixedly provided with a driven rod, and both ends of the driven rod penetrate the lower arm support rod and are fixedly connected to the lower arm inner insertion rod, so that the vertical reciprocating rod drives the lower arm inner insertion rod to move in the same direction.

[0013] Furthermore, the compression hemostasis airbag has a hollow ring structure, an inflation valve is provided on the compression hemostasis airbag, and two sliding retaining rings are flexibly connected to both sides of the compression hemostasis airbag, so that the compression hemostasis airbag and the sliding retaining rings can move relative to each other. The sliding retaining rings are slidably mounted on the lower arm support rod, so that the position of the compression hemostasis airbag on the lower arm support rod can be adjusted arbitrarily.

[0014] Furthermore, when the locking block is not pressed by the pressing and releasing mechanism, it is located in the groove, so that the position of the locking block is relatively fixed when the pressing and releasing mechanism is not pressed. When the gravity cavity is horizontal, the first spring drives the gravity block to rebound to the point tangent to the rotating disk, so that there is no force between the gravity block and the rotating disk.

[0015] A method for using a puncture site compression hemostasis device after cardiac interventional procedures includes the following steps:

[0016] Step 1: After eliminating the puncture point on the patient's wrist and performing other routine bandaging, place the wrist in a sterilized inflation valve. After the fingers pass through the back support strap, press the release mechanism to position it in the palm of the hand. At this time, the protective shell is located on both sides of the elbow joint, and the upper arm extends into the upper arm wrapping strap.

[0017] Step 2: Tighten and fix the upper arm bandage to the upper arm, move the sliding ring to the appropriate position, and inflate the compression hemostasis balloon through the inflation valve to wrap the puncture point. Continue to inflate until the compression hemostasis balloon forms a suitable compression hemostasis effect on the puncture point.

[0018] Step 3: While pressing the button with your finger, the locking block moves out of the groove. At this time, straighten your entire arm to move the upper arm support rod and the lower arm support rod, so that the gravity block contacts one side of the convex ring and the locking block contacts the other side of the convex ring. Then release the button and the locking block enters the groove connected to the convex ring.

[0019] Step 4: When the patient is lying flat, the upper arm is horizontal and the fingers do not press the button. The locking block is always in the outermost groove. At this time, the gravity chamber is horizontal and the gravity block bounces back to the outside of the groove. At this time, the groove of the rotating plate will not produce any resistance to the upper arm support rod. Therefore, the lower arm can be rotated to any angle. Because the patient is lying flat, the lower arm will always be horizontal and upward no matter how it is rotated.

[0020] Step 5: When the patient is semi-reclined, the upper arm is at a certain angle to the horizontal plane. At this time, the gravity block exerts a certain force on the rotating disk under the action of gravity. Rotating the lower arm will create a certain resistance. At this time, you can press the button continuously with your fingers. The locking block is always outside the groove, so you can rotate the lower arm at will. And with the support of the bed, the lower arm is always in a horizontal and upward position.

[0021] Step Six: When the patient is standing and walking, with the upper arm in a vertical position, press the button and straighten the arm. Then release the button, and the locking block will enter the groove connected to the convex ring. At this time, slowly lift the lower arm. The gravity block will slide against the rotating disk surface due to gravity until it enters the first groove and is fixed downwards. At this time, the upper arm and lower arm are at a 90-degree angle and fixed. The patient's lower arm is supported by the lower arm support strap and the back of the hand support strap and is always in a horizontal position. When the patient wants to change the posture after being in this position for a long time, press the button with your fingers to adjust the lower arm to any horizontal upward angle, and then release the button to fix it.

[0022] The beneficial effects achieved by the present invention using the above structure are as follows:

[0023] (1) By reasonably setting the position of the convex ring and groove on the rotating disk, the relative movement of the upper arm support rod and the lower arm support rod is restricted. With the help of the press release mechanism and the gravity adjustment support mechanism, the lower arm is always in a horizontal and upward position when the patient is lying flat, half-lying down and standing and walking. This prevents the lower arm from being horizontally downward for a certain period of time due to careless activity, lack of attention during sleep, muscle fatigue and other reasons, which may cause adverse consequences. The lower arm support belt and the back of the hand support belt support the arm, eliminating the fatigue and discomfort caused by the patient having to keep the lower arm in an upward position at all times.

[0024] (2) Through the combination of the press release mechanism and the gravity adjustment support mechanism, the patient can freely adjust the angle of the arm when lying flat, half-lying down and standing and walking, so as to prevent the arm from being in the same position for a long time and causing soreness and numbness and poor blood circulation.

[0025] (3) When the finger presses the button, it drives the inclined slider to move downward. The inclined surface of the inclined slider pushes the irregular slider to move horizontally. The middle inclined surface of the irregular slider pushes the vertical reciprocating rod to move upward. The vertical reciprocating rod drives the driven rod and then drives the lower arm inner insertion rod and locking block to move upward, so that the locking block leaves the groove, thereby realizing various combined operations. The gravity adjustment support mechanism moves on its own according to the principle of gravity, without the need for various additional operations. Therefore, through the cooperation of the press release mechanism and the gravity adjustment support mechanism, the patient only needs one hand to complete various operations of adjusting and fixing the lower arm when lying flat, semi-lying down and standing and walking, without occupying the other hand, which greatly facilitates the patient's rehabilitation.

[0041] The gravity adjustment support mechanism 2 includes a rotating disk 21, which is concentrically arranged and axially fixed with the protective shell 1, one end of the lower arm support rod 5, and one end of the upper arm support rod 3. A raised ring 22 is provided on the unopened side of the protective shell 1 along the edge of the rotating disk 21. Multiple grooves 23 are arranged in a circular array along the center of the quarter-circle area on the open side of the protective shell 1 along the edge of the rotating disk 21. A gravity cavity 31 is fixedly provided on the upper arm support rod 3 inside the protective shell 1, and a first spring is fixedly provided inside the gravity cavity 31. 33. A gravity block 32 is fixedly provided at one end of the first spring 33. The gravity block 32 is located between the two sides of the rotating disk 21. The lower arm support rod 5 is a hollow structure. A lower arm inner insertion rod 51 is inserted into the lower arm support rod 5. A locking block 52 is fixedly provided at one end of the lower arm inner insertion rod 51 located inside the protective shell 1. The locking block 52 passes through the lower arm support rod 5. A second spring 511 is fixedly provided at the other end of the lower arm inner insertion rod 51. One end of the second spring 511 is fixedly connected to the inner side of one end of the lower arm support rod 5.

[0042] The press-release mechanism 7 includes a fixed rod 71, one end of which is fixedly connected to one end of the lower arm support rod 5. The other end of the fixed rod 71 is fixedly provided with a pressing cavity 72, which is a hollow cavity with one open end. A slide 721 is fixedly provided on the inner surface of the closed end of the pressing cavity 72. The slide 721 is provided with a vertical through hole 722 and a horizontal through hole 723. A pressing button 73 is inserted tightly into the open end of the pressing cavity 72. The pressing button 73 is a hollow cavity with one open end.

[0043] The press-release mechanism 7 includes an irregularly shaped slider 724, which is inserted tightly into the horizontal through hole 723. The inclined surfaces on both sides of the irregularly shaped slider 724 connect with the inclined surfaces of the inclined slider 733. The inclined surface in the middle of the irregularly shaped slider 724 is tightly attached to and penetrates the vertical reciprocating rod 732. The vertical reciprocating rod 732 is inserted into the vertical through hole 722 and penetrates the lower wall of the pressing cavity 72. A driven rod 74 is fixedly provided at one end of the vertical reciprocating rod 732, and both ends of the driven rod 74 penetrate... The lower arm support rod 5 is fixedly connected to the lower arm inner insertion rod 51. The compression hemostasis airbag 6 is a hollow ring structure. The compression hemostasis airbag 6 is equipped with an inflation valve 61. Two sliding retaining rings 62 are flexibly connected on both sides of the compression hemostasis airbag 6. The sliding retaining rings 62 are slidably disposed on the lower arm support rod 5. The locking block 52 is located in the groove 23 when the pressing and releasing mechanism 7 is not pressed. When the gravity chamber 31 is horizontal, the first spring 33 drives the gravity block 32 to rebound to the point tangent to the rotating disk 21.

[0044] A method for using a puncture site compression hemostasis device after cardiac interventional procedures includes the following steps:

[0045] Step 1: After eliminating the puncture point on the patient's wrist and performing other routine bandaging, place the patient in the sterilized inflation valve 61. After the fingers pass through the back support strap 9, press the release mechanism 7 to be located in the palm of the hand. At this time, the protective shell 1 is located on both sides of the elbow joint, and the upper arm extends into the upper arm wrapping strap 4.

[0046] Step 2: Tighten and fix the upper arm wrapping band 4 to the upper arm, move the sliding ring 62 to the appropriate position, inflate the compression hemostasis balloon 6 through the inflation valve 61 to wrap the puncture point, and continue to inflate until the compression hemostasis balloon 6 forms a suitable compression hemostasis effect on the puncture point.

[0047] Step 3: While pressing the button 73 with your finger, the locking block 52 moves outside the groove 23. At this time, straighten your entire arm to drive the upper arm support rod 3 and the lower arm support rod 5 to move, so that the gravity block 32 contacts one side of the convex ring 22 and the locking block 52 contacts the other side of the convex ring 22. At this time, release the button 73 and the locking block 52 enters the groove 23 connected to the convex ring 22.

[0048] Step 4: When the patient is lying flat, the upper arm is in a horizontal position. The fingers do not press the button 73. The locking block 52 is always in the outermost groove 23. At this time, the gravity chamber 31 is in a horizontal position. The gravity block 32 rebounds to the outside of the groove 23. At this time, the groove 23 of the rotating disk 21 will not generate any resistance to the upper arm support rod 3. Therefore, the lower arm can be rotated to any angle. Since the patient is lying flat, the lower arm will always be in a horizontal and upward position no matter how it is rotated.

[0049] Step 5: When the patient is half-lying down, the upper arm is at a certain angle to the horizontal plane. At this time, the gravity block 32 is subjected to gravity and exerts a certain force on the rotating disk 21. Rotating the lower arm will create a certain resistance. At this time, the finger can be used to continuously press the button 73. The locking block 52 is always outside the groove 23, so the lower arm can be rotated at will. And with the support of the bed, the lower arm is always in a horizontal and upward state.

[0050] Step Six: When the patient is standing and walking, with the upper arm in a vertical position, press the button 73 and straighten the arm. Then release the button 73, and the locking block 52 will enter the groove 23 connected to the convex ring 22. At this time, slowly lift the lower arm. The gravity block 32 will slide against the surface of the rotating disk 21 under the action of gravity until it enters the first groove 23 and is fixed downward. At this time, the upper arm and lower arm are at a 90-degree angle and fixed. The patient's lower arm is supported by the lower arm support strap 8 and the back of the hand support strap 9 and is always in a horizontal position. When the patient wants to change the posture after being in this position for a long time, press the button 73 with your fingers. The lower arm can be adjusted to any angle with the horizontal upward direction. Then release the button 73 to fix it.

[0051] In practical use, the device is worn on the arm, the release mechanism 7 is located in the palm of the hand, the protective shell 1 is located on both sides of the elbow joint, the upper arm wrapping band 4 is tightened and fixed to the upper arm, the sliding ring 62 is moved to the appropriate position, and the compression hemostasis airbag 6 is inflated through the inflation valve 61 to form a suitable compression hemostasis effect on the puncture point.

[0052] When the finger presses the button 73, it causes the inclined slider 733 to move downward. The inclined surface of the inclined slider 733 pushes the irregular slider 724 to move horizontally. The middle inclined surface of the irregular slider 724 pushes the vertical reciprocating rod 732 to move upward. The vertical reciprocating rod 732 drives the driven rod 74, which in turn drives the lower arm inner insert rod 51 and the locking block 52 to move upward, so that the locking block 52 leaves the groove 23. The entire arm is straightened, which drives the upper arm support rod 3 and the lower arm support rod 5 to move, so that the gravity block 32 contacts one side of the convex ring 22 and the locking block 52 contacts the other side of the convex ring 22. At this time, the button 73 is released, and the locking block 52 enters the groove 23 connected to the convex ring 22.

[0053] When the patient is lying flat, with the upper arm horizontal and no fingers pressing the button 73, the locking block 52 remains in the outermost groove 23. At this time, the gravity chamber 31 is horizontal, and the gravity block 32 rebounds to the outside of the groove 23. The groove 23 of the rotating disk 21 does not provide any resistance to the upper arm support rod 3, so the lower arm can be rotated to any angle. When the patient is semi-reclined, with the upper arm at a certain angle to the horizontal plane, the gravity block 32 exerts a certain force on the rotating disk 21 under the action of gravity, which creates a certain resistance when rotating the lower arm. At this time, the button 73 can be pressed continuously with the fingers, and the locking block 52 remains outside the groove 23, allowing the lower arm to be rotated arbitrarily. When the patient stands and walks, the upper arm is in a vertical position. After pressing the button 73 and straightening the arm, the button 73 is released, and the locking block 52 enters the groove 23 connected to the convex ring 22. At this time, the lower arm is slowly raised, and the gravity block 32 slides against the surface of the rotating disk 21 under the action of gravity until it enters the first groove 23 and is fixed downward. At this time, the upper arm and lower arm are at a 90-degree angle and fixed. The patient's lower arm is supported by the lower arm support strap 8 and the back of the hand support strap 9 and is always in a horizontal position. When the patient is in this position for a long time and wants to change the posture, the fingers press the button 73 to adjust the lower arm at any angle facing upward, and then the button 73 is released to fix it.
