Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a hemostasis device for femoral artery and vein puncture points after interventional procedures for congenital heart disease in children. Background Technology

[0002] Interventional treatment for congenital heart disease in children is a commonly used minimally invasive method in clinical treatment of congenital heart disease. With its significant advantages such as minimal trauma, rapid recovery, and fewer complications, it is widely used in young children and infants. The femoral artery and vein are the most frequently chosen puncture paths in this type of interventional surgery. Effective hemostasis at the puncture site after surgery is a key link to ensure the surgical effect and reduce the risk of complications, and is directly related to the postoperative recovery process of the child.

[0003] Poor hemostasis at the puncture site can lead to a series of serious problems. If hemostasis is not timely or thorough, it can easily cause complications such as bleeding, hematoma, and pseudoaneurysm. These complications not only prolong the child's hospitalization and increase the medical burden, but may also cause secondary damage to local blood vessels and surrounding tissues, affecting the child's physical recovery and even having an adverse effect on their long-term health. Therefore, reliable hemostasis at the puncture site is crucial to the overall efficacy of interventional treatment for congenital heart disease in children.

[0004] Currently used devices for hemostasis at pediatric femoral artery and vein puncture sites have significant defects in actual use. The devices lack an effective positioning structure design, making it difficult to quickly and stably align the hemostatic point with the puncture site. This problem of insufficient positioning accuracy becomes more prominent after the child's slight activity, and hemostasis is easily lost due to pressure position deviation. Therefore, they cannot meet the core clinical need for accurate and stable hemostasis at the puncture site. Summary of the Invention

[0005] This invention provides a hemostasis device for femoral artery and vein puncture points after interventional procedures for congenital heart disease in children. It addresses the technical problem that existing devices lack an effective positioning structure design, making it difficult to quickly and stably align the hemostasis point with the puncture point, resulting in insufficient positioning accuracy. This problem becomes more prominent after slight activity in the child, and hemostasis may fail due to pressure position deviation.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A hemostasis device for femoral artery and vein puncture points after interventional treatment for congenital heart disease in children includes a transparent positioning cover with straps connected to both ends. A compression component is slidably installed inside the transparent positioning cover. The compression component includes a compression bladder. When the compression bladder is inflated, it expands and deforms to press against the hemostasis point. When the compression bladder is deflated, it contracts and returns to its initial state. A breathable component is installed inside the transparent positioning cover. Several air holes are opened on the side of the transparent positioning cover near the skin, and the breathable component communicates with the air holes.

[0008] Optionally, the positioning component further includes a crosshair positioning line formed on a transparent positioning cover, the transparent positioning cover being fixedly mounted on a pair of straps, and the transparent positioning cover being made of transparent material.

[0009] Optionally, the compression assembly includes a movable cavity within a transparent positioning cover. The transparent positioning cover also has a through hole communicating with the movable cavity. The through hole is located near the skin on the affected side. A fixing frame is slidably installed within the movable cavity. A bolt is threaded onto the transparent positioning cover, and one end of the bolt can abut against the fixing frame. An actuating block is fixedly installed on the fixing frame. A compression bladder is provided on the fixing frame. A ventilation tube controlled by the sealing assembly is fixedly installed on the compression bladder. An inlet hole communicating with the ventilation hole is provided on the actuating block.

[0010] Optionally, the compression bladder is provided with an elastic reset ring, which is elliptical in shape.

[0011] Optionally, the sealing assembly includes a connecting rope fixedly installed on an elastic reset ring, with a sealing block fixedly installed at one end of the connecting rope away from the elastic reset ring, the sealing block being slidably installed inside a venting pipe, and a magnetic block cooperating with the sealing block being fixedly installed inside the venting pipe.

[0012] Optionally, a positioning groove is provided inside the vent pipe, and a limiting pad is fixedly installed on the sealing block. The limiting pad can cooperate with the positioning groove to fix the sealing block.

[0013] Optionally, the sealing block is provided with an auxiliary component, the auxiliary component including a spring fixedly installed inside the sealing block, a connecting plate fixedly installed on the spring, a pull rope fixedly installed on the connecting plate, and the end of the pull rope away from the connecting plate being fixedly connected to the inner wall of the sealing block.

[0014] Optionally, the breathable component includes an airbag fixedly mounted on a transparent positioning cover, the transparent positioning cover having a plurality of air holes on the side near the skin, the air holes communicating with the airbag.

[0015] Optionally, a preheating component is provided inside the transparent positioning cover. The preheating component includes an installation cavity opened inside the transparent positioning cover, and a heating element is provided inside the installation cavity.

[0016] Optionally, the straps are provided with interlocking Velcro straps.

[0017] The beneficial effects of the above-described technical solution of the present invention are as follows:

[0018] In the above solution, the transparent positioning cover is made of transparent material, allowing medical staff to directly observe the real-time condition of the puncture point through the cover. This allows them to determine whether there is bleeding without removing the device, reducing the risk of infection. The crosshair positioning line on the cover provides an intuitive visual reference for puncture point positioning. Medical staff can quickly align the intersection of the crosshair with the puncture hemostasis point, greatly improving positioning efficiency and accuracy, and avoiding hemostasis failure caused by pressure position deviation.

[0019] The movable cavity inside the transparent positioning cover provides sliding space for the fixation frame. Medical staff can move the fixation frame within the movable cavity by using the lever, thereby adjusting the position of the compression bag to accurately align it with the puncture point. When hemostasis is required, gas is introduced into the ventilation tube through the inlet on the lever. The gas enters the compression bag, causing it to expand. The expanded compression bag acts directly on the puncture point through the through-hole, applying continuous and uniform pressure to achieve hemostasis. Attached Figure Description

[0035] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0036] like Figures 1 to 7 As shown, an embodiment of the present invention provides a hemostasis device for femoral artery and vein puncture points after interventional treatment for congenital heart disease in children. The device includes a bandage 10, with a pair of positioning components 20 located at their ends close to each other. The positioning components 20 are used to precisely locate the hemostasis point in conjunction with the bandage 10. A compression component 30 is disposed within a transparent positioning cover 21 in the positioning component 20, and the compression component 30 is used to stop the hemostasis at the hemostasis point in conjunction with the positioning component 20. A ventilating component 60 is disposed within the transparent positioning cover 21, and the ventilating component 60 is used to allow ventilation at the point of contact between the transparent positioning cover 21 and the skin.

[0037] The positioning component 20 is fixed to the puncture area of ​​the femoral artery and vein in the groin of the child by a pair of straps 10. The structural characteristics of the positioning component 20 are used to accurately align with the puncture hemostasis point, ensuring that the compression component 30 can directly act on the target position. With the cooperation of the positioning component 20, the compression component 30 applies stable and appropriate pressure to the puncture point to achieve closure and hemostasis of the vascular puncture site, avoiding bleeding and hematoma formation. The breathable component 60 continuously provides a breathable channel for the contact area between the transparent positioning cover 21 and the skin, reducing the stuffiness and dampness caused by prolonged contact with the local skin, and reducing the risk of skin redness, swelling and allergies. At the same time, the precise positioning of the positioning component 20, together with the fixing effect of the straps 10, ensures that the device will not shift due to the child's movement during the hemostasis process, ensuring the stability of the hemostasis effect.

[0038] like Figures 2 to 3As shown, the positioning component 20 includes a transparent positioning cover 21 with a crosshair positioning line 22. Both ends of the transparent positioning cover 21 are fixedly mounted on a pair of straps 10. The transparent positioning cover 21 is made of transparent material. The transparent material allows medical personnel to directly observe the real-time condition of the puncture point through the cover, enabling them to determine whether bleeding occurs without removing the device, thus reducing the risk of infection. The crosshair positioning line 22 provides an intuitive visual reference for puncture point positioning, allowing medical personnel to quickly align the intersection of the crosshairs with the puncture hemostasis point, significantly improving positioning efficiency and accuracy, and avoiding hemostasis failure caused by pressure displacement.

[0039] like Figure 2 ,to Figure 5 As shown, the compression assembly 30 includes a movable cavity 32 formed within a transparent positioning cover 21. The transparent positioning cover 21 also has a through hole 31 communicating with the movable cavity 32, located near the affected skin side. A fixing frame 33 is slidably installed within the movable cavity 32. A bolt is threaded onto the transparent positioning cover 21, with one end of the bolt abutting against the fixing frame 33. A toggle block 35 is fixedly installed on the fixing frame 33. A compression bladder 34 is provided on the fixing frame 33, and a ventilation tube 37 is provided on the compression bladder 34. A blocking assembly 40 is fixedly installed on the compression bladder 34, controlling the opening and closing of the ventilation tube 37. An inlet hole 36 is formed on the toggle block 35, communicating with the ventilation tube 37.

[0040] The movable cavity 32 inside the transparent positioning cover 21 provides sliding space for the fixation frame 33. Medical staff can move the fixation frame 33 within the movable cavity 32 by using the toggle block 35. After reaching the preset position, it is fixed by bolts, thereby adjusting the position of the compression bag 34 so that it is accurately aligned with the puncture point. When hemostasis is required, gas is introduced into the ventilation tube 37 through the inlet 36 on the toggle block 35. The gas enters the compression bag 34 and inflates it. The inflated compression bag 34 acts directly on the puncture point through the through hole 31, applying continuous and uniform pressure to achieve hemostasis.

[0041] like Figures 3 to 4 As shown, an elastic reset ring 38 is installed on the inner wall of the compression bladder 34. The elastic reset ring 38 is elliptical in shape. The elliptical elastic reset ring 38 inside the compression bladder 34 has good elastic deformation capability. When the compression bladder 34 is inflated, the elastic reset ring 38 deforms together with the compression bladder 34. When hemostasis is completed and the ventilation tube 37 is depressurized, the elastic tension of the elastic reset ring 38 will drive the compression bladder 34 to contract and reset.

[0042] like Figure 3 and Figure 5As shown, the sealing assembly 40 includes a connecting rope 41 fixedly installed on the elastic reset ring 38. A sealing block 42 is fixedly installed at one end of the connecting rope 41 away from the elastic reset ring 38. The sealing block 42 is slidably installed inside the vent pipe 37. A magnetic block 45 that cooperates with the sealing block 42 is fixedly installed inside the vent pipe 37. The sealing component 40 achieves closure of the ventilator 37 through the magnetic attraction between the magnetic block 45 and the sealing block 42, preventing gas leakage from the compression bladder 34, ensuring pressure stability during compression, and thus ensuring continuous and reliable hemostasis. When inflation is required, external force overcomes the attraction between the magnetic block 45 and the sealing block 42, causing the sealing block 42 to slide within the ventilator 37, opening the ventilator 37 channel, and allowing gas to smoothly enter the compression bladder 34. As the compression bladder 34 expands, it causes the elastic reset ring 38 to deform. The connecting rope 41 on the elastic reset ring 38 pulls the sealing block 42 closer to the inlet 36 and seals it. When the sealing block 42 enters the magnetic field of the magnetic block 45, it is attracted again, achieving complete sealing of the ventilator 37, improving the ease of operation of the device and the stability of hemostasis.

[0043] like Figure 5 As shown, a positioning groove 43 is provided inside the ventilation tube 37, and a limiting pad 44 is fixedly installed on the sealing block 42. The limiting pad 44 cooperates with the positioning groove 43 to fix the sealing block 42. The positioning groove 43 in the ventilation tube 37 and the limiting pad 44 on the sealing block 42 cooperate with each other. When the sealing block 42 slides to the closed position in the ventilation tube 37, the limiting pad 44 is engaged in the positioning groove 43, forming a mechanical locking structure. This further enhances the sealing performance of the ventilation tube 37 after closure, prevents gas leakage, ensures long-term stable pressure in the compression bag 34, and guarantees the continuity of hemostasis. When it is necessary to open the ventilation tube 37, the limiting pad 44 disengages from the positioning groove 43 under the action of external force, and the sealing block 42 slides smoothly without affecting gas flow. Through the dual fixation of mechanical locking and magnetic adsorption, the loosening problem that may occur with a single fixation method is avoided, improving the reliability of the opening and closing control of the ventilation tube 37, thereby ensuring the stability and safety of the hemostasis process.

[0044] like Figure 6 As shown, an auxiliary component 50 is provided on the sealing block 42. The auxiliary component 50 includes a spring 51. One end of the spring 51 is fixedly installed inside the sealing block 42, and the other end of the spring 51 is fixedly installed with a connecting plate 52. One end of a pull rope 53 is fixedly installed on the connecting plate 52, and the other end of the pull rope 53 is fixedly connected to the inner wall of the sealing block 42. When the sealing block 42 moves towards the magnetic block 45, the connecting plate 52 abuts against one end of the vent pipe 37, and stretches the spring 51 as the sealing block 42 continues to move. The end of the connecting plate 52 is locked on the outside of the vent pipe 37. When the device is finished, the connecting plate 52 is pulled, and the connecting plate 52 and the pull rope 53 cooperate to pull the sealing block 42 back to its original position. The gas in the pressure bladder 34 is then discharged through the air hole 62, completing the depressurization.

[0045] As shown in the figure Figure 3 and Figure 7 As shown, the breathable component 60 includes an airbag 61. The top of the transparent positioning cover 21 has a mounting groove, within which the airbag 61 is installed. Most of the airbag 61 is exposed, allowing medical personnel to compress it. Several air holes 62 are located on the skin-facing side of the transparent positioning cover 21, communicating with the airbag 61. The airbag 61 on the transparent positioning cover 21 can generate air pressure through compression, causing the gas inside the airbag 61 to continuously escape through the air holes 62 on the skin-facing side of the transparent positioning cover 21, forming an airflow circulation. This airflow between the transparent positioning cover 21 and the skin removes locally generated heat and sweat, keeping the skin dry and breathable. This effectively reduces problems such as stuffiness, redness, and allergies caused by prolonged contact, improving the comfort of the child. Simultaneously, the airflow circulation reduces the risk of local bacterial growth, decreasing the probability of infection. The airbag 61 allows for active control of the ventilation operation, enabling medical personnel to flexibly adjust the ventilation intensity and frequency according to the child's skin condition, adapting to the needs of different children and enhancing the practicality and comfort of the device.

[0046] like Figure 7 As shown, a preheating component 70 is provided inside the transparent positioning cover 21. The preheating component 70 includes a mounting cavity 71 formed within the transparent positioning cover 21, and a heating element 72 is disposed within the mounting cavity 71. When the heating element 72 in the mounting cavity 71 of the transparent positioning cover 21 is energized, it generates heat, which is evenly transferred to the area of ​​the transparent positioning cover 21 in contact with the skin, providing gentle preheating to the local skin. Preheating improves blood circulation in the skin, reducing discomfort caused by cold contact with the device and minimizing skin irritation from low temperatures. This is especially suitable for low-birth-weight premature infants or children with weak constitutions, improving wearing comfort. The heating temperature of the heating element 72 can be controlled within a suitable range for the human body, avoiding overheating and burns. The preheating effect improves the local skin condition, reducing adverse skin reactions. Combined with the breathable component 60, this further enhances the comfort and safety of the device.

[0047] like Figures 1 to 2 As shown, the bandage 10 is equipped with interlocking Velcro straps. These straps achieve quick and easy fixation through adhesive bonding. Medical staff can adjust the tightness of the bandage 10 according to the child's thigh circumference to ensure that the positioning component 20 and the compression component 30 are stably fixed in the puncture area. This avoids problems such as poor blood circulation or skin injury caused by an overly tight bandage 10, or device displacement caused by an overly loose bandage 10. The Velcro straps are easy to apply and require no complicated tools, allowing for quick and easy insertion and removal of the device, thus improving clinical efficiency. Furthermore, the Velcro straps are firmly attached and do not easily fall off during slight child movement, ensuring reliable device fixation and maintaining consistent pressure from the compression component 30 at the puncture point, thus guaranteeing hemostasis.

[0048] The working process of the hemostasis device for femoral artery and vein puncture points after interventional treatment for congenital heart disease provided by this invention is as follows:

[0049] First, based on the child's weight and thigh circumference, the device is secured to the femoral artery and vein puncture area in the groin using Velcro on the strap 10. The adhesive properties of the Velcro allow for quick adjustment of tightness, ensuring device stability and not affecting lower limb blood circulation. During the fixation process, the crosshair 22 on the transparent positioning cover 21 is used to quickly and accurately align the intersection of the crosshairs with the puncture hemostasis point. The transparent positioning cover allows medical staff to observe the puncture point in real time, monitoring for bleeding without removing the device.

[0050] After positioning, the fixed frame 33 inside the movable cavity 32 is slid by the actuating block 35 to further fine-tune the position of the compression bag 34, ensuring it precisely fits the puncture point. Then, the compression bag 34 is inflated through the inlet 36 on the actuating block 35. After inflation, the puncture site is closed and hemostasis is achieved. The magnetic block 45 attracts the sealing block 42, and simultaneously, the limiting pad 44 on the sealing block 42 engages with the positioning groove 43 of the ventilation tube 37. This double fixation ensures the ventilation tube 37 is sealed, preventing gas leakage and maintaining stable pressure. The spring 51 and pull rope 53 inside the sealing block 42 assist in maintaining a stable force state, improving sealing reliability and operational flexibility.

[0051] During hemostasis, the breathable component 60 works continuously, squeezing the airbag 61 to expel gas through the air hole 62, forming an airflow circulation between the transparent positioning cover 21 and the skin, carrying away heat and sweat, and keeping the skin breathable and dry; if the child's skin is sensitive or the ambient temperature is low, the preheating component 70 can be activated, and the heating pad 72 in the mounting cavity 71 is powered to generate gentle heat, preheating the local skin, improving wearing comfort, and reducing adverse skin reactions.

[0052] After hemostasis is completed, pull the connecting plate 52 to disengage the sealing block 42 from the magnetic block 45 and the positioning groove 43, open the vent tube 37, and compress the bladder 34 under the elastic tension of the elastic reset ring 38. Then, loosen the Velcro removal device.

[0053] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
