Description

Technical Field

[0001] The invention relates to the technical field of hemostasis compression, and in particular to a hemostasis compression device for interventional surgery in cardiology. Background Art

[0002] Interventional cardiology surgery is a new technology for diagnosing and treating cardiovascular diseases and an invasive method of diagnosis and treatment. This surgery mainly involves puncturing blood vessels on the surface of the body, inserting a cardiac catheter under continuous projection of digital subtraction, and using specific cardiac catheterization techniques to diagnose and treat heart disease.

[0003] There are many types of interventional cardiology surgeries, such as coronary angiography, percutaneous coronary intervention, radiofrequency ablation, pacemaker implantation, interventional treatment of congenital heart disease, percutaneous aortic valve replacement, etc. Interventional cardiology surgeries have the advantages of less surgical trauma, shorter operation time, and less pain for patients.

[0004] In interventional cardiology surgery, radial artery puncture technology is widely used, and postoperative hemostasis of the radial artery puncture site is increasingly valued. At present, hemostasis of the radial artery puncture site is usually performed using a disposable hemostatic compressor. When using the existing disposable hemostatic compressor, medical staff usually need to preliminarily position the disposable hemostatic compressor before removing the sheath, and fine-tune the compression position and pressure after the sheath is removed.

[0005] The above steps are usually performed by medical staff based on naked eye observation and experience. On the one hand, the accuracy of hemostatic compression points and pressure is greatly affected by subjective factors. If the hemostatic compression points and pressure are inaccurate, it will increase the patient's pain and reduce the efficiency of hemostasis. On the other hand, the operation steps of the disposable hemostatic compressor are relatively complicated, and it is difficult for medical staff to operate. Summary of the invention

[0006] To solve the above problems, the present invention provides a hemostatic compressor for interventional cardiology surgery, which is used to reduce the influence of subjective factors on the accuracy of hemostatic compression points and pressure, and improve the accuracy and convenience of hemostatic compression after interventional cardiology surgery.

[0007] In order to achieve the above-mentioned object, the technical solution of the present invention is as follows: a hemostatic compressor for interventional cardiology surgery, comprising an inner compression ring and an outer support ring, wherein the inner compression ring is detachably connected to the inner wall of the outer support ring;

[0008] The inner compression ring includes a protective belt and a tourniquet, the protective belt contacts the inner wall of the outer support ring, the tourniquet is fixedly connected to the protective belt, and the tourniquet passes through the protective belt;

[0009] The outer support ring is used to limit the position of the inner compression ring. An adaptive compression mechanism is installed inside the outer support ring. The position of the adaptive compression mechanism corresponds to the position of the tourniquet.

[0010] The adaptive compression mechanism includes a squeezing mechanism and a detection mechanism. The detection mechanism is used to detect the humidity information of the tourniquet and output the compression point information and compression force information based on the humidity information analysis. The squeezing mechanism is used to apply pressure to the tourniquet according to the compression point information and compression force information.

[0011] The technical principles of the above scheme are as follows:

[0012] Through the design of detachable connection between the inner compression ring and the outer support ring, the inner compression ring can be removed and replaced, so that the outer support ring can be reused; the tourniquet is used to stop bleeding and compress the patient's radial artery puncture point. The initial hemostatic compression is provided by the extrusion mechanism with a preset compression point and compression force. The subsequent hemostatic compression is obtained by the detection mechanism according to the bleeding situation at the patient's radial artery puncture site to obtain more accurate compression points and compression forces, and the corresponding compression points and compression forces are used through the extrusion mechanism to perform hemostatic compression.

[0013] The above scheme has the following beneficial effects:

[0014] 1. In this solution, the inner compression ring and the outer support ring are designed to be detachably connected. Compared with the existing disposable hemostatic compressor, the inner compression ring can be replaced independently after completing hemostatic compression on the patient's radial artery. The manufacturing cost of the inner compression ring is low, which can effectively reduce the cost of hemostatic compression of the radial artery after cardiology surgery.

[0015] 2. In this solution, the squeezing mechanism and the detection mechanism work together to perform adaptive compression on the radial artery puncture site of the patient. Compared with the existing disposable hemostatic compressor, this reduces the active adjustment process of medical staff, making it more convenient for medical staff to operate when performing hemostatic compression on the patient's radial artery; at the same time, it improves the accuracy of the compression point and compression force, reduces the patient's pain and improves the efficiency of hemostasis.

[0016] 3. In this solution, since the squeezing mechanism and the detection mechanism cooperate to perform adaptive compression on the radial artery puncture site of the patient, when the patient's activity causes a slight change in the position of the compressor, the adaptive compression mechanism can promptly correct the compression point and compression force to ensure effective hemostasis compression on the radial artery puncture site of the patient.

[0017] Furthermore, the tourniquet is fixedly connected to the middle part of the protective belt, and the tourniquet extends outside the upper and lower surfaces of the protective belt.

[0018] Beneficial effect: The height of the tourniquet is set slightly higher than the protective belt, ensuring that one surface of the tourniquet is effectively in contact with the radial artery puncture site of the patient, and the humidity information of the other surface of the tourniquet is effectively detected by the detection mechanism.

[0019] Furthermore, the outer support ring includes an extrusion portion and a clamping portion, the clamping portion is hinged at both ends of the extrusion portion, and a torsion spring is provided at the hinge between the clamping portion and the extrusion portion, which provides a torque for the clamping portion to rotate toward the coverage area of ​​the extrusion portion.

[0020] Beneficial effects: The outer support ring can stabilize the overall structure of the compressor, support and limit the position of the tourniquet, and the compressor can be easily worn by pushing the clamping part outward.

[0021] Furthermore, a plurality of positioning shafts are arranged on the inner side wall of the extrusion part, and a plurality of positioning holes corresponding to the positions of the positioning shafts are opened on the protective belt, and the positioning holes are slidably matched with the positioning shafts.

[0022] Beneficial effect: Through the cooperation between the positioning shaft and the positioning hole, the disassembly and installation of the inner compression ring can be completed conveniently, and the position of the tourniquet can be accurate.

[0023] Furthermore, any clamping part is hinged with a locking belt, the other clamping part is fixedly connected with a locking buckle, the front surface of the locking belt is provided with a first adhesive part, and the rear surface of the locking belt is provided with a first Velcro.

[0024] Beneficial effect: The outer support ring is assisted in fixation by the locking belt and the locking buckle, so that the outer support ring can adapt to the arms of different sizes of different patients.

[0025] Furthermore, a fold is provided on the surface of the protective belt, and the position of the fold corresponds to the position of the hinge between the clamping part and the extrusion part.

[0026] Beneficial effect: The fold can facilitate the coordinated rotation of the protective belt during the rotation of the clamping ring, thereby avoiding displacement of the protective belt and stabilizing its position.

[0027] Furthermore, the detection mechanism includes a plurality of partitions provided in the extrusion portion, a plurality of humidity sensors are provided on the partitions, and the humidity sensor signals are connected to the controller;

[0028] The humidity sensor is used to collect the humidity signal of the tourniquet, and the controller is used to obtain the humidity signals collected by each humidity sensor, obtain the change trend of the humidity signal based on the humidity signals collected by each humidity sensor, and output the compression point information based on the change trend analysis of the humidity signal; obtain the distance between the humidity point greater than the threshold and the compression point based on the humidity signal collected by each humidity sensor, and output the compression intensity information based on the distance analysis between the humidity point greater than the threshold and the compression point.

[0029] Beneficial effects: Based on the humidity change trend of the blood on the tourniquet, the humidity near the blood center (radial artery puncture site) is usually higher because it is the first to contact the blood. As the blood spreads to the surrounding, the humidity on the tourniquet becomes lower and lower, thereby judging the compression point; based on the distance between the humidity point greater than the threshold and the compression point, if the humidity is still high at a large distance from the compression point, the blood is continuing to spread, and the compression force at the compression position needs to be increased, thereby adjusting the compression force.

[0030] Furthermore, the extrusion mechanism includes a pressurized chamber formed between a plurality of partitions, each of which is provided with an air bag, each of which is connected to an air pump through a pipeline, each of which is provided with an electromagnetic valve, and each of the air pump and the electromagnetic valve is connected to a controller signal, and the controller is used to control the operation of the air pump and the electromagnetic valve based on the information of the compression point and the information of the compression force;

[0031] A plurality of pressure detection points are arranged on the lower surface of the extrusion part, and the pressure detection points are connected to the controller signal. The controller is used to obtain the pressure information of each part within the coverage area of ​​the extrusion part based on the pressure signals collected by the pressure detection points.

[0032] Beneficial effect: By adjusting the inflation volume through a number of independently adjustable air bags, the compression position and compression intensity can be adjusted. The compressor can complete the operation independently without the assistance of medical staff.

[0033] Furthermore, a display is fixedly connected to the surface of the extrusion part, and the display is connected to the controller signal. The controller is used to send compression point information and compression force information to the display, and the display is used to display the compression point information and compression force information.

[0034] Beneficial effects: The display shows the patient's radial artery compression point and compression strength, so that medical staff can intuitively obtain the current hemostasis compression situation.

[0035] Furthermore, a plurality of second adhesive portions are fixedly connected to the inner side wall of the clamping portion, a plurality of second Velcro portions are arranged on the surface of the protective belt, and the protective belt is detachably connected to the clamping portion via the second adhesive portions and the second Velcro portions.

[0036] Beneficial effect: The second adhesive portion and the second Velcro are used in conjunction with each other to fix the auxiliary protective belt, thereby improving the stability of the compressor during use.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] The following is further described in detail through specific implementation methods:

[0050] Embodiment 1:

[0051] A hemostatic compression device for interventional cardiology surgery comprises an inner compression ring 200 and an outer support ring 100, wherein the inner compression ring 200 is detachably connected to the inner wall of the outer support ring 100. Figure 1 and attached Figure 2 As shown, the inner compression ring 200 and the outer support ring 100 have similar structures, the difference between them is that the inner compression ring 200 is detachably mounted on the inner wall of the inner support ring, and the diameter of the inner compression ring 200 is smaller than that of the outer support ring 100 .

[0052] Specifically, the inner compression ring 200 includes a protective belt 3 and a tourniquet 5. The tourniquet 5 is preferably made of sterile gauze or approximately sterile gauze; the protective belt 3 contacts the inner wall of the outer support ring 100, and the tourniquet 5 is fixedly connected to the protective belt 3. In order to ensure that the tourniquet 5 accurately performs hemostatic compression on the radial artery puncture site of the patient, the present embodiment sets the tourniquet 5 in the middle of the protective belt 3. Secondly, it is necessary to ensure that the tourniquet 5 passes through the protective belt 3 so that the tourniquet 5 contacts the radial artery puncture site of the patient. In order to ensure that one surface of the tourniquet 5 effectively contacts the radial artery puncture site of the patient, the tourniquet 5 can be extended outside the upper and lower surfaces of the protective belt 3, that is, the upper and lower surfaces of the tourniquet 5 are higher than the upper and lower surfaces of the protective belt 3.

[0053] The outer support ring 100 is used to limit the position of the inner compression ring 200. Specifically, the outer support ring 100 includes a pressing portion 6 and a clamping portion 7. Figure 1 and attached Figure 2 As shown, the thickness of the squeezing part 6 is relatively thick, while the thickness of the clamping part 7 is relatively thin, and the clamping part 7 is hinged at both ends of the squeezing part 6; both the squeezing part 6 and the clamping part 7 are arc-shaped structures to fit the patient's arm. A torsion spring is provided at the hinge between the clamping part 7 and the squeezing part 6, and the torsion spring provides a torque for the clamping part 7 to rotate toward the area covered by the squeezing part 6, so that the clamping parts 7 at both ends of the squeezing part 6 automatically retract inward when not subject to other external forces, thereby conveniently realizing the wearing of the hemostatic compressor.

[0054] On the basis of the wearing of the above-mentioned hemostatic compressor, in order to further promote the wearing stability of the compressor, a locking belt 8 can be hinged on a clamping part 7, a locking buckle 9 can be fixedly connected to the other clamping part 7, a first adhesive part is provided on the front surface of the locking belt 8, and a first hook is provided on the rear surface of the locking belt 8. Specifically, the first adhesive part and the first hook can be respectively set as the loop surface and hook surface of Velcro, so that the compressor can be further fixed conveniently; in addition, an elastic locking belt 8 can be used, and buckles can be set at the end and tail of the compressor, which can also achieve further fixation of the compressor. The Velcro structure used in this embodiment can extend the locking belt 8 in the opposite direction after passing the locking buckle 9, so that the loop surface and hook surface of the Velcro overlap, thereby achieving the fixation of the locking belt 8.

[0055] Combined with Figure 3 -Attached Figure 6 As shown, an adaptive compression mechanism is installed in the outer support ring 100, and the position of the adaptive compression mechanism corresponds to the position of the tourniquet 5 to ensure accurate adaptive compression position and compression force adjustment. The adaptive compression mechanism includes a squeezing mechanism and a detection mechanism, and the detection mechanism is used to detect the humidity information of the tourniquet 5, and output the compression point information and compression force information based on the humidity information analysis.

[0056] Specifically, the detection mechanism includes a plurality of partitions 2 opened in the extrusion part 6, and a plurality of humidity sensors are arranged on the partitions 2. In this embodiment, the humidity sensors are arranged at the intersection of the partitions 2 to ensure that the humidity of the tourniquet 5 in the covered area can be detected, and the humidity sensor signal is connected to the controller. In addition, a battery compartment is arranged in the extrusion part 6, and the battery compartment is used to store batteries (the batteries are mainly used to power various electrical components). Correspondingly, in order to facilitate charging of the batteries, a charging hole is installed on the side wall of the extrusion part 6, and the batteries are charged through the charging hole, so that the outer support ring 100 can be partially reused.

[0057] The humidity sensor is used to collect the humidity signal of the tourniquet 5, and the controller is used to obtain the humidity signals collected by each humidity sensor, obtain the change trend of the humidity signal based on the humidity signals collected by each humidity sensor, and output the compression point information based on the change trend analysis of the humidity signal; based on the humidity change trend of the blood on the tourniquet 5, the humidity near the blood center (radial artery puncture position) is usually higher because it is the first to contact the blood. As the blood diffuses to the surrounding area, the humidity on the tourniquet 5 becomes lower and lower, thereby judging the compression point.

[0058] The humidity sensor is also used to obtain the distance between the humidity point greater than the threshold and the compression point based on the humidity signal collected by each humidity sensor, and output the compression intensity information based on the distance analysis between the humidity point greater than the threshold and the compression point; based on the distance between the humidity point greater than the threshold and the compression point, if there is still a large humidity at a large distance from the compression point, the blood is continuing to spread, and the compression intensity at the compression position needs to be increased, thereby adjusting the compression intensity.

[0059] The squeezing mechanism is used to apply pressure to the tourniquet 5 according to the compression point information and the compression force information. Specifically, the squeezing mechanism includes a pressurized chamber formed between a plurality of partitions 2, each of which is fixedly connected with an air bag 1, each of which is connected with an air pump through a pipeline, each of which is provided with a solenoid valve, and each of which is connected to a controller signal, and the controller is used to control the operation of the air pump and the solenoid valve based on the compression point information and the compression force information.

[0060] In addition, in order to measure the actual pressure value generated by the squeezing part 6 at the radial artery puncture site of the patient, a number of pressure detection points 4 are arranged on the lower surface of the squeezing part 6. The pressure detection points 4 are arranged alternately with the humidity sensors to avoid interference between the temperature and humidity information collection caused by the overlap of the two. The pressure detection points 4 are connected to the controller signal, and the controller is used to obtain the pressure information of each part in the coverage area of ​​the squeezing part 6 based on the pressure signal collected by the pressure detection point 4. At the same time, the controller is also used to collect the pressure change frequency and amplitude collected by the pressure detection point 4, estimate the radial artery pulsation based on the frequency and amplitude, and control the inflation volume of the airbag 1 according to the collected pressure change frequency and amplitude. For example: if the pressure change frequency and amplitude are significantly reduced, there may be a situation of over-extrusion, so the inflation volume of the airbag 1 is reduced to reduce the squeezing force on the patient's puncture site, avoiding excessive squeezing of the patient's puncture site.

[0061] The hemostatic compressor can adjust the inflation volume through a plurality of independently adjustable air bags 1, and can adjust the compression position and compression intensity. In addition, the controller adjusts the compression intensity according to the continuous compression time of the radial artery puncture site of the patient. The adjustment relationship between the pressure and time can be preset by medical staff according to the individual situation of the patient, or the controller can adjust the pressure according to the initial preset. The initial preset pressure adjustment rule can adapt to more than 80% of patients. Therefore, after the hemostatic compressor is worn and the information is preset, it does not need the assistance of medical staff to operate, and the compressor position adjustment and compression intensity adjustment can be completed autonomously.

[0062] The specific implementation process is as follows: when the locking belt 8 is not locked, the clamping part 7 is pushed to both sides so that the hemostatic compressor has a larger opening space, and the hemostatic compressor is initially worn on the patient's arm. The medical staff pulls out the sheath and presses the puncture site with their hands at the same time, and then makes the squeezing part 6 cover the patient's radial artery puncture site. The medical staff releases the compressed puncture site and locks the locking belt 8 at the same time. Then the adaptive compression mechanism independently adjusts the compression position and compression strength, so as to conveniently complete the wearing of the hemostatic compressor, and the compressor can independently and accurately perform hemostatic compression on the patient's radial artery puncture site, and at the same time the medical staff can independently observe the radial artery pulsation and bleeding.

[0063] Embodiment 2:

[0064] As attached Figure 7 As shown, the difference from Example 1 is that a plurality of positioning shafts are integrally formed on the inner wall of the extrusion portion 6, the positions of the positioning shafts can be randomly arranged, and the length of the positioning shafts should not be too long to avoid interference with the patient's arm. Accordingly, a plurality of positioning holes 11 corresponding to the positions of the positioning shafts are provided on the protective belt 3, and the positioning holes 11 are slidably matched with the positioning shafts. When installing the protective belt 3, the positioning shafts and the positioning holes 11 are used for auxiliary positioning installation, so that the protective belt 3 can be conveniently installed.

[0065] In order to prevent the protective belt 3 from shifting during the movement of the clamping part 7, a fold is provided on the surface of the protective belt 3, and the position of the fold corresponds to the position of the hinge between the clamping part 7 and the extrusion part 6; the fold can facilitate the coordinated rotation of the protective belt 3 during the rotation of the clamping ring, thereby maintaining the stability of the protective belt 3.

[0066] A plurality of second adhesive portions are fixedly connected to the inner wall of the clamping portion 7, and a plurality of second Velcro portions 10 are provided on the surface of the protective belt 3. The protective belt 3 is detachably connected to the clamping portion 7 through the second adhesive portions and the second Velcro portions 10. The second adhesive portions and the second Velcro portions 10 are used in conjunction with each other to assist in fixing the protective belt 3 and improve the stability of the compressor during use.

[0067] Embodiment 3:

[0068] The difference from Example 2 is that a display 300 is fixedly connected to the surface of the extrusion part 6, and the display 300 is connected to the controller signal. The controller is used to send pressure point information and pressure intensity information to the display 300, and the display 300 is used to display the pressure point information and pressure intensity information.

[0069] Specifically, the display 300 displays the shape of the tourniquet 5 , and displays in real time the humidity information of each area on the tourniquet 5 , as well as the points where the tourniquet 5 is compressed and the information of the compression force.

[0070] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
