Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically, it relates to a compression hemostasis device for the puncture site after femoral artery intervention. Background Art

[0002] Femoral artery intervention is a technique for diagnosis and treatment by inserting a catheter through the femoral artery, which is widely used in the diagnosis and treatment of cardiovascular diseases. This technique uses the femoral artery as a passage to send the catheter to the target blood vessel site for operations such as angiography, angioplasty, and stent implantation.

[0003] After femoral artery intervention, hemostasis at the puncture site is an important link to ensure the safety of patients and postoperative recovery. Currently, the commonly used hemostasis methods in clinical practice include manual compression, vascular closure devices, arterial compression hemostasis devices, and arterial hemostatic patches, etc. However, these methods still have the following problems: (1) The fixation methods of some existing compression hemostasis devices are prone to displacement of the compression hemostasis device when the patient moves, turns over, or has limb movements, causing the compression point to deviate from the puncture site, resulting in hemostasis failure or the formation of a hematoma; (2) Some existing compression hemostasis devices cover the puncture site, making it inconvenient to directly observe the condition of the wound, such as whether there is blood oozing, hematoma formation, skin color change, etc.; (3) Some existing compression hemostasis devices lack precise pressure measurement, and medical staff can only rely on experience and the touch of the dorsalis pedis artery pulsation to judge whether the compression is appropriate.

[0004] Therefore, the present invention aims to provide a compression hemostasis device for the puncture site after femoral artery intervention to solve the above problems. Summary of the Invention

[0005] The object of the present invention is to provide a compression hemostasis device for the puncture site after femoral artery intervention. Through the hemostasis structure, the present invention can achieve the function of medical staff pressing and stopping bleeding at the puncture site of the patient. At the same time, through the sensor combined with the intelligent control system, the inflation volume in the airbag can be automatically adjusted, enabling the compression hemostasis device to adjust the pressing force on the puncture site according to different pressing stages, reducing the instability of the hemostasis effect caused by differences in human experience, and thus improving the hemostasis effect on the puncture opening of the patient. Moreover, the sliding connection structure I allows relative movement between the hemostasis structure and the fixing plate, so that when the patient moves, turns over, or performs limb movements, it can avoid the compression point deviating from the puncture site due to the contact and friction between the compression hemostasis device and the body, preventing the occurrence of hemostasis failure or hematoma formation, thereby ensuring that the compression point can always act precisely on the puncture site.

[0006] The above technical object of the present invention is achieved through the following technical solutions: A compression hemostasis device for the puncture site after femoral artery intervention, including a fixing plate, both ends of the fixing plate are provided with arc-shaped splints, the end of the arc-shaped splint away from the fixing plate is provided with an elastic strap, the end of the elastic strap away from the arc-shaped splint is provided with a magic tape, the bottom of the fixing plate is provided with a sliding connection structure I, and the bottom of the sliding connection structure I is provided with a hemostasis structure. The sliding connection structure I is used to help generate relative movement between the hemostasis structure and the fixing plate, and the hemostasis structure is used to compress the puncture site to play a hemostasis role.

[0007] By adopting the above technical solutions, arc-shaped splints are provided at both ends of the fixing plate, an elastic strap is provided at the end of the arc-shaped splint away from the fixing plate, and a magic tape is provided at the end of the elastic strap away from the arc-shaped splint. The combination of the elastic strap and the magic tape can adapt to the leg sizes of patients with different body types. Moreover, a sliding connection structure I is provided at the bottom of the fixing plate, and a hemostasis structure is provided at the bottom of the sliding connection structure I. The hemostasis structure helps compress the puncture site to play a hemostasis role, and the sliding connection structure I allows relative movement between the hemostasis structure and the fixing plate. When the patient moves, turns over, or makes limb movements, it can avoid the compression point deviating from the puncture site due to the contact friction between the compression hemostasis device and the body, preventing the occurrence of hemostasis failure or hematoma formation, thereby ensuring that the compression point can always accurately act on the puncture site.

[0008] The present invention is further configured as: The hemostasis structure includes a pressure plate and a pressure airbag; the pressure plate is connected to the bottom of the fixing plate, and the pressure airbag is connected to the bottom of the pressure plate.

[0009] By adopting the above technical solutions, the pressure plate is connected to the bottom of the fixing plate, and the pressure airbag is connected to the bottom of the pressure plate. By inflating the pressure airbag, it can simulate the medical staff pressing on the patient's puncture site to achieve the effect of pressing for hemostasis. At the same time, by adjusting the inflation volume in the pressure airbag, different pressing forces can be generated on the puncture site, and thus different pressing situations can be adjusted according to different pressing stages, improving the practicability of the device.

[0010] The present invention is further configured as: A hemostatic patch is further provided at the bottom of the pressure airbag.

[0011] By adopting the above technical solutions, a hemostatic patch is also provided at the bottom of the pressure airbag. The drug components in the hemostatic patch can further promote blood coagulation, quickly seal the blood vessel breakage at the wound, reduce bleeding, and at the same time the drug components can inhibit the inflammatory reaction at the puncture site, thereby accelerating the healing of the puncture site.

[0012] The present invention is further configured such that: the first sliding connection structure includes a first spiral spring, a first limiting rod, a first sliding block, and a first connecting block; a first sliding groove is provided at the bottom of the fixed plate, two ends of the first limiting rod are fixedly connected to opposite side walls of the first sliding groove, the first sliding block is sleeved on the first limiting rod and slides along the first sliding groove, the first spiral spring is sleeved on the first limiting rod and its two ends are respectively connected to the first sliding groove and the first sliding block, and two ends of the first connecting block are respectively connected to the first sliding block and the hemostasis structure.

[0013] By adopting the above technical solution, two ends of the first limiting rod are fixedly connected to opposite side walls of the first sliding groove, the first sliding block is sleeved on the first limiting rod and slides along the first sliding groove, the first spiral spring is sleeved on the first limiting rod and its two ends are respectively connected to the first sliding groove and the first sliding block, so that the first sliding block can move left and right along the first limiting rod. At the same time, two ends of the first connecting block are respectively connected to the first sliding block and the hemostasis structure, and thus the hemostasis structure can be driven to move left and right. When the displacement is generated due to the contact and friction between the compression hemostasis device and the body, only the fixed plate and the patient's body generate displacement. At this time, the hemostasis structure is still located at the puncture point, so as to ensure that the compression point can always accurately act on the puncture point.

[0014] The present invention is further configured such that: a support structure is provided on the arc-shaped splint, and the support structure is used to relieve the pressure outside the puncture point during the compression hemostasis process. The support structure includes a support soft pad and a second sliding connection structure.

[0015] By adopting the above technical solution, a support structure is provided on the arc-shaped splint. The support structure can make a gap be formed between the arc-shaped plate and the patient's leg position, preventing the arc-shaped splint from closely adhering to the patient's leg skin, enabling the situation of the puncture opening to be observed, such as whether there is blood oozing, hematoma formation, and skin color change, and also relieving the pressure outside the puncture point during the compression hemostasis process, avoiding excessive compression of the leg blood vessels and facilitating the adjustment of the compression intensity at the puncture point.

[0016] The present invention is further configured such that: the second sliding connection structure includes a second spiral spring, a second limiting rod, a second sliding block, and a second connecting block; a second sliding groove is provided on the side wall of the arc-shaped splint, two ends of the second limiting rod are fixedly connected to opposite side walls of the second sliding groove, the second sliding block is sleeved on the second limiting rod and slides along the second sliding groove, the second spiral spring is sleeved on the second limiting rod and its two ends are respectively connected to the second sliding groove and the second sliding block, and two ends of the second connecting block are respectively connected to the second sliding block and the support soft pad.

[0017] By adopting the above technical solution, a second sliding groove is provided on the side wall of the arc-shaped splint. Both ends of the second limiting rod are fixedly connected to the opposite side walls of the second sliding groove. The second sliding block is sleeved on the second limiting rod and slides along the second sliding groove, enabling the second sliding block to slide up and down along the second limiting rod. The second spiral spring is sleeved on the second limiting rod and its two ends are respectively connected to the second sliding groove and the second sliding block. Both ends of the second connecting block are respectively connected to the second sliding block and the supporting soft pad, enabling the movement of the supporting structure to be driven. Furthermore, when the compression hemostasis device comes into contact with and rubs against the body to generate displacement, only the arc-shaped splint generates displacement with the patient's body. At this time, the supporting structure still maintains the initial position of contacting the leg, thereby ensuring that the compression point can always act precisely on the puncture point while further enhancing the stability of the overall structure of the compression hemostasis device.

[0018] The present invention is further configured such that: a waist strap is provided on the fixing plate.

[0019] By adopting the above technical solution, a waist strap is provided on the fixing plate. The waist strap can further fix the compression hemostasis device. At the same time, by being provided at the waist, it is also convenient for medical staff to fix the compression hemostasis device, improving the comfort of the patient during use.

[0020] The present invention is further configured such that: a sensor is provided between the pressurizing airbag and the pressurizing plate.

[0021] By adopting the above technical solution, a sensor is provided between the pressurizing airbag and the pressurizing plate. The sensor can accurately obtain the pressure exerted by the compression hemostasis device on the puncture point during the compression hemostasis process, solving the limitation problem in the traditional treatment process that mainly relies on the personal experience of medical staff to judge whether the pressure is appropriate, enabling more medical staff to accurately perform pressing adjustments and improving the applicability of the compression hemostasis device.

[0022] The present invention is further configured such that: an electric air pump and a PLC controller are further provided on the fixing plate; the PLC controller is communicatively connected to both the sensor and the electric air pump, and the PLC controller is integrated with an intelligent control system.

[0023] By adopting the above technical solution, an electric air pump and a PLC controller are further provided on the fixing plate. The PLC controller is communicatively connected to both the sensor and the electric air pump. The PLC controller is integrated with an intelligent control system. The sensor obtains the pressure on the pressurizing airbag and transmits it to the PLC controller. The PLC controller analyzes the current pressure of the pressurizing airbag to determine whether it is in the optimal inflation state corresponding to the pressurizing stage, and then automatically controls the pressurizing airbag through the intelligent control system to ensure the accuracy of the hemostasis effect and improve the hemostasis efficiency.

[0024] The present invention is further configured such that: the intelligent control system includes a data acquisition module, a data processing module, an intelligent analysis module, an automatic control module, and a voice broadcast module; The data acquisition module is used to receive the electrical signals transmitted by the sensors, and convert the electrical signals into digital signals and then transmit them to the data processing module; the data processing module is used to receive the digital signals transmitted by the data acquisition module, and perform signal filtering and format conversion to obtain accurate digital signals and transmit them to the intelligent analysis module; the intelligent analysis module is used to receive the digital signals transmitted by the data processing module and perform analysis, generate control signals and transmit them to the automatic control module and the voice broadcast module simultaneously; the automatic control module is used to receive the control signals transmitted by the intelligent analysis module, and convert them into control instructions to automatically control the electric air pump; the voice broadcast module is used to receive the control signals transmitted by the intelligent analysis module, and generate the status information of the compression hemostasis device in combination with the time stamp and then broadcast it.

At the same time, the voice broadcast module can accurately obtain the hemostasis time of the current compression hemostasis device in combination with the time stamp, and then perform voice broadcast through the voice broadcast module to feed back to the medical staff in a timely manner, further improving the hemostasis efficiency. Among them, the data processing module receives the digital information in the data acquisition module, and then performs data filtering and format conversion on the digital information to obtain complete and standardized signal data. The processed data will be more standardized and tidy, facilitating subsequent analysis and processing. At the same time, sending the processed data to the intelligent analysis module can improve the analysis accuracy and facilitate the generation of more accurate control information. Secondly, the processed data can also be stored in the database according to needs, which is convenient for subsequent query and use.

[0026] In summary, the present invention has the following beneficial effects: The sliding connection structure I in the present invention allows relative movement between the hemostasis structure and the fixing plate, ensuring that when the patient moves, turns over, or the limb moves, the hemostasis structure can still accurately act on the puncture point, avoiding the compression point deviating due to friction, thereby effectively preventing hemostasis failure or hematoma formation; Through the combination of the arc-shaped splint, the elastic bandage, and the magic tape in the present invention, the leg sizes of patients with different body types can be adapted, ensuring that the device is firmly fixed on the patient's leg and avoiding hemostasis failure caused by the device loosening; In the hemostasis structure of the present invention, inflating the pressurized airbag simulates the pressing of medical staff for hemostasis. At the same time, the pressing force can be adjusted at different pressing stages by adjusting the inflation volume, improving the practicability and adaptability of the device. In addition, the hemostatic patch at the bottom of the pressurized airbag can promote blood coagulation, reduce bleeding, inhibit the inflammatory response, and accelerate the healing of the puncture site. The support structure on the arc-shaped splint of the present invention can create a gap with the patient's leg, preventing the arc-shaped splint from tightly adhering to the leg skin, thereby relieving the pressure outside the puncture site, preventing excessive compression of the leg blood vessels, and improving the patient's comfort. The present invention uses a sensor to monitor the hemostasis pressure in real time and transmits the data to the PLC controller. Combined with the intelligent control system, it realizes the automatic control of the pressurized airbag, ensuring the accuracy of the hemostasis effect. The voice broadcast module combined with the timestamp function can real-time feedback the status of the compression hemostasis device, facilitating medical staff to adjust the operation in time and further improving the hemostasis efficiency. Overall, the present invention combines the sliding connection structure I and the support structure to ensure that when the patient moves, the compression point of the compression hemostasis device can still accurately act on the puncture site, while further improving the overall structural stability of the device and avoiding hemostasis failure caused by friction or displacement.
