Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to an electrocardiogram chest suction ball auxiliary fixation device. Background Art

[0002] ECG chest suction ball, also known as adsorption electrode or chest suction cup, is a common electrode used to detect chest bioelectric signals in ECG examination. The working principle of ECG chest suction ball is based on the principle of negative pressure adsorption. When using it, medical staff will squeeze the rubber ball on the suction ball to expel the air, then place it on the patient's chest skin and let go. Since the air inside the suction ball is expelled, negative pressure is formed, so it can be tightly adsorbed on the patient's skin;

[0003] When medical staff squeeze the chest suction ball to expel the air inside it, they cannot accurately control the pressure applied by their fingers on the chest suction ball. If the squeezing force is too great, the suction ball will form negative pressure and be adsorbed on the patient's chest, which will not only cause redness, swelling, pain, or even damage or subcutaneous bleeding on the patient's skin, causing damage to the patient's skin, but also excessive negative pressure will cause the patient to feel strong discomfort or pain, increase the patient's breathing amplitude during the electrocardiogram test, affect the quality of electrocardiogram collection, and interfere with the doctor's diagnosis. Conversely, when the squeezing force is too light, the negative pressure inside the suction ball will be insufficient, affecting the adsorption effect of the suction ball, resulting in the suction ball being unable to fit closely to the patient's chest, thereby affecting the quality of electrocardiogram signal collection, and due to poor adsorption effect, medical staff need to try or adjust the position of the suction ball multiple times, thereby increasing the risk of operational errors.

[0004] Therefore, the present invention proposes an electrocardiogram chest suction ball auxiliary fixation device to solve the above problems. Summary of the invention

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the present invention provides an electrocardiogram chest suction ball auxiliary fixation device, which has the following beneficial effects:

[0020] 1. The squeezing force control mechanism is set to limit the moving position of the squeezing plate, so as to control the squeezing force of the squeezing plate on the airbag. This can not only avoid the patient's skin redness, pain, damage or subcutaneous bleeding caused by excessive squeezing force, but also reduce the patient's discomfort during the electrocardiogram test, improve the patient's comfort and satisfaction, and reduce the mistakes caused by improper operation of medical staff. There is no need to try multiple times or adjust the position of the suction ball, which reduces the complexity of operation and improves work efficiency. In addition, the appropriate squeezing force can ensure that the suction ball fits tightly to the patient's chest, slowing down the patient's breathing amplitude, making it easier for medical staff to accurately collect electrocardiogram signals, avoiding the situation where the signal collection quality is reduced due to the patient's excessive breathing amplitude, thereby improving the clarity and accuracy of the electrocardiogram.

[0021] 2. The springs, positioning columns and positioning holes provided can facilitate medical staff to adjust and fix the position of the limit ring, change the moving distance of the extrusion plate and the extrusion amplitude of the airbag, and adjust the pressure of the extrusion plate on the airbag. Not only can the position of the limit ring be flexibly adjusted according to the patient's skin type, sensitivity and thickness factors, thereby ensuring that the pressure of the extrusion plate on the airbag is moderate, which helps to further reduce the risk of skin damage and improve the patient's comfort and medical safety, but the comfortable extrusion experience helps to reduce the patient's tension and fear, and improve the acceptance of electrocardiogram testing. Patients are more willing to cooperate with the test, so that medical staff can obtain more accurate electrocardiogram data.

[0022] 3. Through the provided lifting plate, connecting block, suction rod, suction pipe and exhaust hole, the suction rod can be pushed out of the suction pipe synchronously during the squeezing process of the airbag by the squeezing plate, and the air inside the airbag can be extracted and discharged from the exhaust hole. By synchronously pushing the suction rod to exhaust, not only the pressure inside the airbag can be accurately controlled, but also the medical staff can adjust the pressure of the airbag according to the actual situation and needs of the patient to achieve the best treatment effect. Moreover, by accurately controlling the pressure and exhaust process of the airbag, the risk of skin damage caused by excessive pressure can be reduced, the skin integrity of the patient can be protected, and the potential risk of infection can be reduced;

[0023] Among them, the extrusion plates on both sides are connected by the set lifting plate and connecting block, so that during the extrusion plate extrusion of the airbag, the airbag can be evenly squeezed from both sides at the same time, which not only avoids the situation where one side of the airbag is subjected to excessive or insufficient force, but also helps to maintain the shape and stability of the airbag, prevent deformation or damage caused by uneven force, and extend the service life of the airbag. Moreover, the uniform extrusion can ensure that the air in the airbag is effectively discharged, thereby achieving the expected extrusion effect, realizing better treatment effect, improving the clarity of electrocardiogram acquisition and reducing patient skin damage.

[0024] 4. The anti-deflation mechanism can automatically drive the rubber sealing ring to descend when the suction cup is adsorbed on the patient's skin, and fit tightly to the connection between the suction cup and the patient's skin. This not only effectively prevents the gap caused by the chest rise and fall and skin unevenness caused by the patient's breathing, and ensures the stability of the negative pressure inside the suction cup, thereby improving the stability and clarity of the ECG signal, but also the fit of the rubber sealing ring reduces the movement and friction of the suction cup on the skin, reduces the risk of skin damage to patients caused by long-term friction, reduces redness, swelling, pain and even breakage, and improves the patient's comfort and satisfaction.

[0038] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] An electrocardiogram chest suction ball auxiliary fixation device of this embodiment, such as Figure 1 - Figure 8 As shown, it includes an airbag 1, a connecting tube 2 is fixedly connected to the lower end of the airbag 1, a suction cup 3 is fixedly connected to the lower end of the connecting tube 2, a connecting plate 4 is fixedly connected to the outer surface of the connecting tube 2, a data transmission line connection port 5 is fixedly connected to one side of the connecting plate 4, a slide groove 8 is provided on the upper end surface of the connecting plate 4, and also includes an extrusion force control mechanism and an anti-leakage mechanism, and the extrusion force control mechanism is used to help medical personnel control the pressing force on the airbag 1.

[0040] In this embodiment, Figure 3As shown, the extrusion force control mechanism includes a symmetrically arranged moving plate 601, and the moving plate 601 is symmetrically fixedly connected with a sliding column 602 on one side close to the connecting plate 4. The sliding column 602 is slidably connected to the connecting plate 4, and the outer surface of the sliding column 602 is sleeved with a limiting ring 609. The upper end surface of the moving plate 601 is fixedly connected with an extrusion plate 603, and the extrusion plates 603 are located on both sides of the airbag 1. When the medical staff presses the extrusion plates 603 on both sides to approach each other to squeeze the airbag 1, the extrusion plate 603 will drive the moving plate 601 to synchronously approach the connecting plate 4 through the sliding column 602, and at the same time shorten the distance between the moving plate 601 and the limiting ring 609. When the moving plate 601 contacts the limiting ring 609, the moving plate 601 will not be able to move further. At this time, the extrusion plate 603 connected to the upper end surface of the moving plate 601 will complete the extrusion of the airbag 1, thereby controlling the extrusion force of the extrusion plate 603 on the airbag 1.

[0041] In this embodiment, Figure 3 and Figure 4 As shown, a transverse plate 610 is fixedly connected between the limiting rings 609 on the same side, a connecting column 612 is fixedly connected at the center of the upper end surface of the transverse plate 610, and a connecting rod 613 is rotatably connected to the connecting column 612. A movable frame 611 is rotatably connected between the ends of the two connecting rods 613 away from the connecting column 612, and the movable frame 611 is slidably connected to the upper end surface of the connecting plate 4. When the movable frame 611 slides on the upper end surface of the connecting plate 4, the transverse plate 610 can be pulled closer to or away from the connecting plate 4 through the arranged connecting rod 613 and connecting column 612, and the limiting ring 609 can be driven to slide on the outer surface of the sliding column 602.

[0042] In this embodiment, Figure 5 As shown, the movable frame 611 is fixedly connected to a movable block 614 on the side away from the connecting pipe 2. The movable block 614 is slidably connected in the slide groove 8. Positioning holes 618 are equidistantly provided at the bottom of the slide groove 8. A positioning column 615 is slidably connected through the movable block 614. The positioning column 615 and the positioning hole 618 are engaged with each other. When the positioning column 615 is driven to be engaged in the positioning hole 618, the movable block 614 can be limited to a specified position inside the slide groove 8.

[0043] In this embodiment, Figure 5 As shown, a handle 616 is fixedly connected to the upper end of the positioning column 615, and a spring 617 is fixedly connected between the lower end surface of the handle 616 and the upper end surface of the moving block 614. The spring 617 is sleeved on the outer surface of the positioning column 615. When the medical staff pulls the handle 616 to drive the positioning column 615 to slide vertically upward on the moving block 614, the spring 617 connected between the handle 616 and the moving block 614 will be pulled at the same time. When the medical staff releases the handle 616, the rebound force of the spring 617 will pull the handle 616 close to the moving block 614 again, and push the positioning column 615 to slide into the moving block 614.

[0044] In this embodiment, Figure 2 As shown, an exhaust pipe 605 is fixedly connected to the upper end of the airbag 1, and the exhaust pipe 605 is connected to the airbag 1. An exhaust rod 606 is slidably connected to the upper end of the exhaust pipe 605. An exhaust hole 608 is provided on the outer surface of the exhaust pipe 605. A one-way valve is provided at the exhaust hole 608 and the connection between the exhaust pipe 605 and the airbag 1. When the exhaust rod 606 slides out of the exhaust pipe 605, the exhaust rod 606 will draw the air inside the airbag 1 into the exhaust pipe 605. When the exhaust rod 606 slides into the exhaust pipe 605, the air inside the exhaust pipe 605 will be discharged through the exhaust hole 608.

[0045] In this embodiment, Figure 2 As shown, the upper end of the exhaust rod 606 is fixedly connected to a connecting block 607, and the side of the connecting block 607 close to the extrusion plate 603 is rotatably connected to a lifting plate 604, and the side of the lifting plate 604 away from the connecting block 607 is rotatably connected to the upper end of the extrusion plate 603. When the extrusion plates 603 move horizontally towards or away from each other, the lifting plate 604 can push the connecting block 607 to move up and down, driving the exhaust rod 606 to slide vertically up and down.

[0046] In the prior art, medical personnel usually use their fingers to squeeze the suction ball to expel the air inside it. However, due to personnel uncertainties, medical personnel cannot accurately control the pressure applied by their fingers to the chest suction ball. If the squeezing force is too great, the suction ball will form a negative pressure when adsorbed on the patient's chest, which will not only cause redness, swelling, pain, or even damage or subcutaneous bleeding on the patient's skin, causing damage to the patient's skin, but also excessive negative pressure will cause the patient to feel strong discomfort or pain, increase the patient's breathing amplitude during the electrocardiogram test, affect the quality of electrocardiogram collection, and interfere with the doctor's diagnosis. Conversely, when the squeezing force is too small, the negative pressure inside the suction ball will be insufficient, affecting the adsorption effect of the suction ball, resulting in the suction ball being unable to fit closely to the patient's chest, thereby affecting the quality of electrocardiogram signal collection, and due to the poor adsorption effect, medical staff need to use more The invention can limit the moving position of the squeezing plate 603 to control the squeezing force of the squeezing plate 603 on the airbag 1, which can avoid the patient's skin redness, pain, damage or subcutaneous bleeding caused by excessive squeezing force, reduce the patient's discomfort during electrocardiogram testing, improve the patient's comfort and satisfaction, and reduce the mistakes caused by improper operation of medical staff. There is no need to try or adjust the position of the suction ball for multiple times, which reduces the complexity of operation and improves work efficiency. The appropriate squeezing force can ensure that the suction ball fits tightly to the patient's chest, slows down the patient's breathing amplitude, and facilitates the medical staff to accurately collect electrocardiogram signals, thereby avoiding the situation where the signal collection quality is reduced due to the patient's excessive breathing amplitude, thereby improving the clarity and accuracy of the electrocardiogram.

[0047] In other aspects, this embodiment also provides an anti-leakage mechanism for sealing the suction cup 3 around, such as Figure 1 , Figure 7 and Figure 8 As shown, the anti-leakage mechanism includes a rubber sealing ring 701, which is sleeved on the outer surface of the suction cup 3. The upper end surface of the rubber sealing ring 701 is symmetrically fixedly connected with a lifting column 702, and the lifting columns 702 are all penetrated and slidably connected to the connecting plate 4.

[0048] In this embodiment, Figure 7As shown, the upper ends of the lifting columns 702 are fixedly connected with fixed blocks 703, and the fixed blocks 703 are rotatably connected with the push plates 704 on the side close to the moving plate 601, and the push plates 704 are rotatably connected with the linkage columns 705 on the side away from the fixed blocks 703. The linkage columns 705 are fixedly connected to the side walls of the moving plate 601. When the moving plate 601 moves horizontally, the linkage columns 705 connected on both sides can drive one end of the push plate 704 to move synchronously, thereby changing the state of the push plate 704, so that the push plate 704 pushes the fixed block 703 to drive the lifting columns 702 to slide up and down on the connecting plate 4.

[0049] In the prior art, when the suction ball is attached to the patient's chest, the chest rise and fall caused by the patient's breathing and the unevenness of the skin will easily cause a gap to form at the edge where the suction ball contacts the patient's skin, resulting in the disappearance of the negative pressure inside the suction ball. The appearance of the gap will not only lead to loose contact between the suction ball and the skin, thereby affecting the stability and clarity of the ECG signal, causing fluctuations or interference in the collected ECG signal, and affecting the doctor's accurate judgment, but also the existence of the gap will cause the suction ball to move or rub on the skin, especially when the patient is breathing, this friction will be aggravated, and long-term friction will cause skin damage, redness, swelling, pain and even To prevent the damage of the suction cup 3, compared with the prior art, when the suction cup 3 is adsorbed on the patient's skin, the rubber sealing ring 701 can be automatically driven to descend and fit tightly at the connection between the suction cup 3 and the patient's skin, which not only effectively prevents the gap caused by the chest rise and fall and skin unevenness caused by the patient's breathing, and ensures the stability of the negative pressure inside the suction cup 3, thereby improving the stability and clarity of the ECG signal, but also the fit of the rubber sealing ring 701 reduces the movement and friction of the suction cup 3 on the skin, reduces the risk of damage to the patient's skin due to long-term friction, reduces redness, swelling, pain and even damage, and improves the patient's comfort and satisfaction.

[0050] The working process and principle involved in the overall content of the above embodiment are as follows:

[0051] When the medical staff needs to perform an electrocardiogram on the patient, they first let the patient lie flat on the test bed, then take the airbag 1, and according to the patient's skin type, sensitivity and thickness factors, lift the handle 616 upwards, pull the positioning column 615 to slide upwards on the moving block 614, and at the same time make the positioning column 615 slide out of the positioning hole 618 opened at the bottom of the slide groove 8, and pull the spring 617 connected between the handle 616 and the moving block 614. When the positioning column 615 and the positioning hole 618 are completely separated, the medical staff can pull the handle 616 horizontally, and pull the moving block 614 to slide horizontally in the slide groove 8 through the positioning column 615, and drive the moving frame 611 connected to the side wall of the moving block 614 to move synchronously on the upper end surface of the connecting plate 4. During the movement of the moving frame 611, the moving frame 611 can pull one end of the connecting rod 613 connected to the two sides to move synchronously, so that the connecting rod 613 moves out of the water. The horizontal shape moves to the inclined shape. With the change of the state of the connecting rod 613, the connecting rod 613 will pull the horizontal plate 610 synchronously close to the connecting plate 4 through the connecting column 612 connected to one end away from the moving frame 611, and make the limiting ring 609 connected on both sides of the horizontal plate 610 move synchronously on the outer surface of the sliding column 602. When the position adjustment of the limiting ring 609 is completed, the medical staff can release the handle 616. Through the rebound force of the spring 617 connected between the handle 616 and the moving block 614, the handle 616 will be pulled close to the moving block 614, and the positioning column 615 connected to the lower end of the handle 616 will be pushed to slide downward on the moving block 614 again, and slide into the other positioning holes 618 opened at the bottom of the slide groove 8, so as to limit the position of the moving block 614, so as to fix the adjusted position of the limiting ring 609 through the moving frame 611, the connecting rod 613, the connecting column 612 and the horizontal plate 610.

[0052] After the position of the limiting ring 609 is fixed, the medical staff can press the squeezing plates 603 on both sides so that the squeezing plates 603 squeeze the airbag 1 to discharge the air inside the airbag 1, and push the sliding column 602 to slide into the connecting plate 4 through the moving plate 601 connected to the lower end face of the squeezing plate 603. In the process of the moving plate 601 approaching the connecting plate 4, the distance between the moving plate 601 and the limiting ring 609 will gradually shorten. After the moving plate 601 and the limiting ring 609 are fitted together, they will be blocked by the limiting ring 609 and cannot move further. At this time, the squeezing plate 603 connected to the upper end face of the moving plate 601 will complete the squeezing of the airbag 1, so that the medical staff can control the squeezing of the airbag 1. The force can not only avoid the occurrence of skin redness, pain, damage or subcutaneous bleeding caused by excessive squeezing force, reduce the discomfort of patients during ECG testing, and improve the comfort and satisfaction of patients, but also reduce the mistakes caused by improper operation of medical staff. There is no need to try multiple times or adjust the position of the suction ball, which reduces the complexity of operation and improves work efficiency. The appropriate squeezing force can ensure that the suction ball fits tightly to the patient's chest, slowing down the patient's breathing amplitude, making it easier for medical staff to accurately collect ECG signals, avoiding the decrease in signal collection quality due to excessive breathing amplitude of patients, thereby improving the clarity and accuracy of the ECG.

[0053] When the medical staff adjusts the position of the limiting ring 609, it is convenient for the medical staff to adjust the movable distance of the movable plate 601 and the squeezing plate 603, so as to adjust the pressure of the squeezing plate 603 on the airbag 1. Not only can the position of the limiting ring 609 be flexibly adjusted according to the patient's skin type, sensitivity and thickness factors, so as to ensure that the pressure of the squeezing plate 603 on the airbag 1 is moderate, which helps to further reduce the risk of skin damage and improve the patient's comfort and medical safety, but also the comfortable squeezing experience helps to reduce the patient's tension and fear, improve the acceptance of electrocardiogram testing, and the patient is more willing to cooperate with the test, so that the medical staff can obtain more accurate electrocardiogram data;

[0054] During the process of the pressing plates 603 approaching each other to press the airbag 1, the pressing plates 603 will push the lower end of the lifting plate 604 rotatably connected to the upper end face to move, causing the lifting plate 604 to move from an inclined state to a vertical state. As the state of the lifting plate 604 changes, the two lifting plates 604 will push the connecting block 607 connected to the end far from the pressing plate 603 to move upward, and at the same time pull the air extraction rod 606 connected to the lower end of the connecting block 607 out of the inside of the air extraction pipe 605, pumping the air inside the airbag 1 into the air extraction pipe 605. By synchronously pushing the air extraction rod 606 to exhaust, not only can the pressure inside the airbag 1 be precisely controlled, and medical staff can adjust the pressure of the airbag 1 according to the actual situation and needs of the patient to achieve the best treatment effect, but also by precisely controlling the pressure and exhaust process of the airbag 1, the risk of skin damage caused by excessive pressure can be reduced, protecting the skin integrity of the patient and reducing the potential infection risk;

[0055] During the process of the pressing plates 603 approaching each other to press the airbag 1 and driving the air extraction rod 606 through the lifting plate 604 and the connecting block 607, affected by the lifting plate 604 and the connecting block 607, the two pressing plates 603 on both sides will be connected to each other, enabling uniform pressing on both sides of the airbag 1 simultaneously during the process of the pressing plates 603 pressing the airbag 1. This not only avoids the situation where one side of the airbag 1 is overloaded or underloaded, which helps to maintain the shape and stability of the airbag 1, prevent deformation or damage caused by uneven stress, and extend the service life of the airbag 1, but also uniform pressing can ensure that the air inside the airbag 1 is effectively discharged, thereby achieving the expected pressing effect, realizing a better treatment effect, improving the clarity of electrocardiogram acquisition and reducing skin damage to the patient;

[0056] When the moving plate 601 approaches the connecting plate 4 and drives the squeezing plate 603 to squeeze the airbag 1, the moving plate 601 will synchronously drive the linkage columns 705 on both sides to move horizontally, and make the linkage columns 705 move the lower end of the push plate 704 close to the connecting plate 4, so that the push plate 704 moves from the inclined state to the vertical state. When the state of the push plate 704 changes, the push plate 704 will push the fixed block 703 connected to the rotation at one end away from the linkage column 705 to move, and push the lifting column 702 connected to the lower end of the fixed block 703 to slide vertically upward on the connecting plate 4, driving the rubber sealing ring 701 connected between the lower ends of the lifting columns 702 to rise synchronously, and then the medical staff can place the suction cup 3 at the designated position on the patient's chest, and then release the squeezing plates 603 on both sides. The rebound force of the airbag 1 between the squeezing plates 603 will push the squeezing plates 603 on both sides away from each other, so that the airbag 1 The suction cup 3 arranged at the lower end instantly forms a negative pressure state, is adsorbed on the patient's chest, and drives the moving plate 601 connected to the lower end of the squeezing plate 603 away from the connecting plate 4. During the reverse movement of the moving plate 601, the moving plate 601 will push the rubber sealing ring 701 to descend synchronously through the linkage column 705, the push plate 704, the fixed block 703 and the lifting column 702, so that the rubber sealing ring 701 fits tightly at the connection between the suction cup 3 and the patient's skin, which not only effectively prevents the gap caused by the chest ups and downs and skin unevenness caused by the patient's breathing, ensures the stability of the negative pressure inside the suction cup 3, thereby improving the stability and clarity of the ECG signal, but also the fit of the rubber sealing ring 701 reduces the movement and friction of the suction cup 3 on the skin, reduces the risk of patient skin damage caused by long-term friction, reduces redness, swelling, pain and even breakage, and improves the patient's comfort and satisfaction.
