Description

Technical Field

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

[0002] The diagnosis and treatment of cardiovascular and cerebrovascular diseases require vascular puncture, among which femoral artery puncture is one of the most important ways of interventional diagnosis and treatment. After femoral artery interventional surgery, it is necessary to stop bleeding at the femoral artery puncture site. Common hemostasis methods include compression hemostasis and occlusion hemostasis. Occlusion hemostasis usually uses imported medical equipment, which is expensive and requires doctors to have more experience in use. Therefore, it has not been widely promoted in my country. Femoral artery compression hemostasis is more commonly used clinically. Femoral artery compression hemostasis method first presses the vascular puncture site with a finger for 10-15 minutes, and then uses a sandbag or hemostat to press the puncture site for 4-6 hours. Doctors who perform interventional surgery attach great importance to the process of femoral artery compression hemostasis, because if the femoral artery puncture site compression hemostasis fails, it will cause a series of serious problems such as puncture site bleeding, hematoma, pseudoaneurysm, venous thrombosis, etc.

[0003] At present, band-shaped triangular hemostats and three-point lever compression hemostats are more commonly used. At the same time, staff from many universities, hospitals and scientific research institutions are also actively researching more comprehensive femoral artery hemostasis devices. Among them, Wang Qian and others from the First Affiliated Hospital of the Chinese People's Liberation Army Army Medical University applied for an invention patent in 2024: a femoral artery hemostasis compressor with alarm function (CN117898782A). The patent is simple to operate, the compression position is accurate, the support point is not easy to slide, and it also has an alarm function. However, the device restricts the movement of the patient's thigh, and it is easy to cause changes in the pressure of the compression point due to body movement. Among them, Sun Xiaolei and others from the Affiliated Hospital of Southwest Medical University applied for an invention patent in 2017: a puncture site compression machine after cardiovascular intervention (CN107997801A). The patent is flexible in movement, small in space requirements, and the compression height, position, and angle are infinitely adjustable. However, the base (body) of the compression mechanism has only one physical connection (pressing head) with the patient's thigh compression point, and its compression stability is slightly insufficient.

DETAILED DESCRIPTION

[0021] Example 1

[0022] In order to make the technical means adopted by the present invention and the purpose achieved easy to understand, the present invention is further explained below in combination with a specific implementation method. A combined stepless decompression femoral artery compression hemostasis device includes a hip fixation device 1 and a leg fixation device 2.

After the device fixing through rod 1.7 passes through the front and rear through grooves 1.1, a through rod annular lock buckle 1.8 for locking the hip fixing device 1 and the leg fixing device 2 is provided on the primary annular groove 1.7.1.

[0025] Among them, the hip fixing device 1 and the leg fixing device 2 are both provided with left and right through holes 1.9, and the device fixing through rod 1.7 is provided with a secondary annular groove 1.7.2. After the device fixing through rod 1.7 passes through the left and right through holes 1.9, a through rod annular lock buckle 1.8 for locking the device fixing through rod 1.7 is provided on the secondary annular groove 1.7.2.

[0026] The buttocks fixing device 1 is provided with an anti-itching groove 1.10 and a first push rod receiving groove 1.3 for receiving a first anti-itching push rod 1.2.

[0027] The leg fixing device 2 is provided with an anti-itching groove 1.10 and a second push rod receiving groove 2.8 for receiving a second anti-itching push rod 2.9.

[0028] The leg fixing device 2 is provided with a fixing belt fixing rod 2.3 for fixing the elastic fixing belt 2.2, and a fixing belt pressure adjustment knob 2.4 for adjusting the contraction of the elastic fixing belt 2.2. The leg fixing device 2 is provided with a connecting belt direction adjustment buckle 2.7 for fixing the hemostat connecting belt 2.6.

[0029] Wherein, a pressure regulating hemostat 2.5 is arranged on the fixed hemostat connecting belt 2.6, and the center of the pressure regulating hemostat 2.5 coincides with the blood vessel puncture point.

[0030] Among them, the center of the pressure-regulating hemostat 2.5 is a solid threaded cylindrical structure, the bottom end of which is connected to the central pressure point 2.5.4, and the top end is connected to the central point pressure regulating knob 2.5.1; the front of the pressure-regulating hemostat 2.5 is also provided with a plurality of primary compression ring pressure regulating knobs 2.5.2, which correspond to the primary compression ring 2.5.5 at the back, and also adopt a threaded cylindrical structure, and the primary compression ring pressure regulating knob 2.5.2 can be retracted up and down and is flexibly connected to the primary compression ring 2.5.5; the front of the pressure-regulating hemostat 2.5 is also provided with a plurality of secondary compression ring pressure regulating knobs 2.5.3, which correspond to the secondary compression ring 2.5.6 at the back, and also adopt a threaded cylindrical structure, and the secondary compression ring pressure regulating knob 2.5.3 can be retracted up and down and is flexibly connected to the secondary compression ring 2.5.6.

[0031] Among them, the hemostat connecting belt 2.6 is connected to the load-bearing Velcro 3.1 of the compression stepless decompression device 3 after passing through the connecting belt direction adjustment buckle 2.7. The load-bearing Velcro 3.1 is connected to the basic counterweight container 3.2 and the weight-reducing container 3.3 by a wedge-shaped structure. The weight-reducing container 3.3 is connected to the storage container 3.5 through a liquid leakage pipeline 3.4, and a low-speed regulating valve is arranged on the liquid leakage pipeline 3.4.

[0032] The main function of the compression stepless pressure relief device 3 is to provide a bidirectional stable pulling force for the pressure regulating hemostat 2.5, and has a stepless pressure relief function. The load-bearing Velcro 3.1 can be stably adhered to the elastic fixing belt 2.2 and transmit the bidirectional pulling force generated by the gravity of the container below to the pressure regulating hemostat 2.5 through the elastic fixing belt 2.2.

[0033] like Figure 1-Figure 5 As shown: a combined stepless decompression femoral artery compression hemostasis device. Before the patient undergoes the puncture operation, the medical staff first selects a hip fixing device 1, a leg fixing device 2, a thigh elastic fixing belt 2.2 and a hemostat connecting belt 2.6 of suitable specifications according to the patient's height, weight and thigh circumference. First, the selected hip fixing device 1 and leg fixing device 2 are inserted and fixed from above through the wedge-shaped fixing groove 1.4 of the connecting surface, and the device fixing through rod 1.7 is used for penetration connection, and then the through rod annular lock buckle 1.8 is fixed to the primary annular groove 1.7.1 on the device fixing through rod 1.7, so as to lock the two ends of the combined device. The assembled device is placed on the bed as a whole, and the patient lies on it. According to the length of the patient's leg circumference, a thigh elastic fixing belt 2.2 of appropriate length is selected to wrap the thigh and connect it to the leg fixing device 2 with the fixing belt fixing rod 2.3, and then the fixing belt pressure adjustment knob 2.4 is used to adjust the wrapping tightness of the thigh elastic fixing belt 2.2 and the patient's thigh. When the tightness is suitable, the locking button of the fixing belt pressure adjustment knob 2.4 is pressed, so that the thigh elastic fixing belt 2.2 fixes the patient's leg and the leg fixing device 2 relatively. This method can reduce the puncture point pressing displacement caused by the patient moving the thigh. One end of the hip fixing strap 1.5 is connected to the strap fixing beam 1.6 on one side of the hip fixing device 1 and passes around the hip from above. The other end of the hip fixing strap 1.5 is connected to the strap fixing beam 1.6 on the other side of the hip fixing device 1 and tied with a movable rope buckle, so that the patient's hip movement is also restricted. When the doctor completes the femoral artery puncture operation, he first presses the puncture point of the femoral artery with his fingers. The medical staff uses a medical marker pen to draw a circle with the blood vessel puncture point as the center and the minimum circumscribed circle diameter of the pressure regulating hemostat 2.5 as the diameter. Because the diameter of this circle is the same as the minimum circumscribed circle diameter of the pressure regulating hemostat 2.5, and the central pressure point 2.5.4 is located at the exact center of the minimum circumscribed circle, when the pressure regulating hemostat 2.5 is pressed on the thigh, we only need to adjust the position of the pressure regulating hemostat 2.5 so that its four corners coincide with the circle drawn by the marker pen on the thigh, so as to ensure that the central pressure point 2.5.4 is accurately pressed on the blood vessel puncture point.

[0034] Before the doctor finishes pressing with his fingers to stop the bleeding, the medical staff still needs to do some preparation work. They must select two hemostat connecting belts 2.6 that are suitable for the patient's thigh circumference, insert one end into the pressure-regulating hemostat 2.5, and pass the other end through the connecting belt direction adjustment buckle 2.7, and finally pass through the leg fixing device 2 and connect it to the load-bearing Velcro 3.1. A fixed amount of water is injected into the basic counterweight container 3.2 and the weight-reducing container 3.3 (the volume of water can be adjusted according to the patient's leg circumference). The basic counterweight container 3.2, the weight-reducing container 3.3 and the load-bearing Velcro 3.1 are all connected by a wedge-shaped structure, and then the upper end of the liquid leakage pipeline 3.4 is connected to the weight-reducing container 3.3, and the lower end is connected to the storage container 3.5.

[0035] Once the preparations are done, the stepless decompression femoral artery compression hemostasis can be implemented. At the moment when the doctor releases the finger pressing the hemostasis, the center point of the pressure regulating hemostat 2.5 is aligned with the center point of the finger just pressing to press the femoral artery puncture point. In order to press the blood vessel puncture point more accurately, the position of the pressure regulating hemostat 2.5 can be slightly adjusted to make the four vertices of the pressure regulating hemostat 2.5 coincide with the circumference of the circle just drawn on the thigh, so that the center of the pressure regulating hemostat 2.5 can be guaranteed to coincide with the blood vessel puncture point. Then adjust the connection belt direction adjustment buckle 2.7 according to the overlap between the thigh and the hemostat connection belt 2.6, try to make the hemostat connection belt 2.6 completely overlap with the lower part of the thigh, and under the gravity of the basic counterweight container 3.2 and the weight reduction container 3.3, the hemostat connection belt 2.6 is attached to the outer side of the thigh from two directions, and the pressure regulating hemostat 2.5 is used to continuously compress the femoral artery puncture point for hemostasis.

[0036] Example 2

[0037] During the compression hemostasis process, the pressing pressure should be gradually reduced. The previous methods or devices all reduce the pressure value artificially after a period of time, which will cause a sudden change in the pressing pressure, which is not conducive to the healing of the vascular puncture point. In the present device, due to the use of the compression stepless decompression device 3, the decompression process of the compression point is changed to an automatic and controllable stepless decompression, and the effect is significantly better than the traditional manual staged decompression method. The specific method of use is as follows: the weight reduction container 3.3 is connected to the storage container 3.5 through the liquid drainage pipeline 3.4, and the counterweight liquid (usually water) in the weight reduction container 3.3 will flow to the storage container 3.5 through the liquid drainage pipeline 3.4 due to gravity. A drip rate adjustment switch is provided in the middle of the liquid drainage pipeline 3.4. The speed of the liquid flowing to the storage container 3.5 is controlled by adjusting the cross-sectional size of the liquid pipeline. Under normal circumstances, it takes 2-4 hours for the liquid in the weight reduction container 3.3 to be emptied. During the process of the liquid in the weight-reducing container 3.3 flowing to the storage container 3.5, the downward pulling force of the load-bearing Velcro 3.1 is also infinitely reduced due to the change of gravity, thus realizing infinite pressure reduction at the pressure point without manual intervention and electronic mechanical equipment. After the use of the compression infinite pressure reduction device 3, the compounding liquid inside can be released, and when the device is used next time, different volumes of counterweight liquid can be injected according to the required pressure strength.

[0038] Example 3

[0039] There are connecting slots 2.5.7 on both sides of the pressure regulating hemostat 2.5, which are connected to the hemostat connecting belt 2.6 through the wedge-shaped interfaces on both sides of the pressure regulating hemostat 2.5. The center of the pressure regulating hemostat 2.5 is a solid threaded cylindrical structure, the bottom end is connected to the central pressure point 2.5.4, and the top end is connected to the central point pressure regulating knob 2.5.1. When the central point pressure regulating knob 2.5.1 rotates clockwise and moves downward, the cylinder moves downward, and the downward pressure of the central pressure point 2.5.4 increases. There is a pointing arrow on the top of the central point pressure regulating knob 2.5.1, and the pressure value can be judged by observing the direction of the arrow. Similarly, when the central point pressure regulating knob 2.5.1 rotates counterclockwise and moves upward, the height of the cylinder increases, and the downward pressure of the central pressure point 2.5.4 decreases. When the hemostat connection belt 2.6 provides the first downward pressure for the pressure regulating hemostat 2.5 from both sides, the center point pressure regulating knob 2.5.1 provides a more precise secondary controllable pressure for the center pressure point 2.5.4. The front of the pressure regulating hemostat 2.5 is also provided with 6 primary pressure ring pressure regulating knobs 2.5.2, corresponding to the primary pressure ring 2.5.5 at the back, which also adopts a threaded cylindrical structure. The 6 cylinders that can be extended up and down are flexibly connected to the primary pressure ring 2.5.5. The 6 primary pressure ring pressure regulating knobs 2.5.2 select different pressure fingers, so that the pressure of the primary pressure ring 2.5.5 can have obvious directional directivity, and the pressure value at the proximal end is usually higher than that at the distal end. Similarly, the secondary pressure ring pressure regulating knob 2.5.3 and the secondary pressure ring 2.5.6 also provide secondary pressure and have pressure directionality. Through the adjustable primary and secondary compression rings, the adjustable central compression point and the adjustable stepless compression decompression device 3, a total of 4 levels of adjustable compression hemostasis can be provided for the blood vessel puncture point.

[0040] Example 4

[0041] In the process of using this device to perform femoral artery compression hemostasis, in order to make the patient's vascular puncture point heal quickly, a delayed compression scheme is usually adopted, and the compression time can be as long as 3-5 hours. During such a long period of time, the doctor will also ask the patient not to move the buttocks and puncture the thigh, which is bound to cause local blood circulation, muscle tension or itching in the patient's buttocks and legs. If the patient can't help itching or moves the buttocks or legs uncontrollably, this will instantly affect the pressure value of the puncture point compression, thereby destroying the healed vascular puncture point structure. In order to solve this problem, the device is provided with an anti-itching groove 1.10 that penetrates the upper and lower structures in the buttocks fixing device 1 and the leg fixing device 2. When the patient feels itchy in the buttocks or legs, the family can take out the anti-itching push rod 1.2 from the push rod storage groove 1.3, and push and pull up and down along a certain anti-itching groove 1.10. The front end protruding part of the anti-itching push rod 1.2 presses back and forth for the patient's buttocks or legs during the up and down movement to achieve the effect of relieving itching.

[0042] Example 5

[0043] When using the device to perform femoral artery compression hemostasis, if an emergency requires the patient to be moved, the device fixed through rod 1.7 can be used to penetrate horizontally through the left and right through holes 1.9, and the through rod annular lock buckle 1.8 can be used to lock the through rod to the secondary annular slot 1.7.2 on the device fixed through rod 1.7. Medical staff can use the four horizontal handles extending from the left and right sides of the device to lift the patient and move him.

[0044] Example 6

[0045] The present invention aims to provide a combined stepless decompression femoral artery compression hemostasis device, which can not only ensure the compression hemostasis effect of the femoral artery vascular trauma point, but also improve the comfort of the patient's buttocks and legs, and reduce the workload of nursing staff.

[0046] In order to achieve the above-mentioned purpose, the present invention provides a combined stepless decompression femoral artery compression hemostasis device, which comprises three parts: a buttocks fixing device 1, a leg fixing device 2, and a compression stepless decompression device 3. The three devices are combined together by a physical connector to effectively compress the puncture point after femoral artery surgery. The entire compression process does not require power supply, the operation is simple, and each component has a variety of specifications that can be spliced ​​arbitrarily to suit patients of various body shapes. The preferred technical solution is:

[0047] The hip fixation device 1, the leg fixation device 2 and the compression stepless decompression device 3 all have different sizes to accommodate patients of different body shapes. Any size of the hip fixation device 1 and the leg fixation device 2 can be connected and assembled through the standard device fixing through rod 1.7.

[0048] You can also choose different lengths of the load-bearing Velcro 3.1 according to the thickness of the patient's thigh at the puncture point to better match the pressure point.

[0049] The hip fixation device 1 and the leg fixation device 2 are connected by a device fixing through rod 1.7. Different hip fixation devices 1 and leg fixation devices 2 can be selected according to the patient's height, weight or hip circumference. The connection interface of each device is of standard size, so the device fixing through rod 1.7 can adapt to hip fixation devices 1 and leg fixation devices 2 of various specifications.

[0050] The thigh elastic fixing belt 2.2 can be selected in different lengths according to the size of the patient's thigh, fixed by a fixing belt fixing rod 2.3, and the pressure is adjusted by a fixing belt pressure adjustment knob 2.4.

[0051] The pressure regulating hemostat 2.5 can provide 5 points of adjustable pressure, providing effective annular layered pressure for the puncture point.

[0052] The connecting belt direction adjustment buckle 2.7 can finely adjust the compression angle according to the patient's leg shape.

[0053] The compression stepless decompression device 3 utilizes a preset gravity effect to provide continuous and stable bidirectional stretching and compression for the puncture point, and has a stable stepless uniform decompression effect.

[0054] As an improvement of the present invention, both the buttocks fixing device 1 and the leg fixing device 2 are equipped with an anti-itching push rod. Since the compression and hemostasis time of the puncture point is relatively long, many patients move their bodies due to poor blood circulation or local itching, thus causing re-bleeding at the puncture point. The anti-itching push rod can perform through-type movement from the upper and lower ends to provide massage for the buttocks and leg muscles to relieve local itching, and the anti-itching push rod can be completely stored in the push rod storage slot for easy access.

[0055] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
