All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The core of the invention is to provide a prevention and treatment instrument for deep venous thrombosis, the inflation and deflation rhythm of the air bag of the prevention and treatment instrument is consistent with the diastole and contraction rhythm of the heart, and the prevention and treatment instrument can provide a promoting force for diastole and contraction of the heart, so that blood can better reach the tail end of a limb, and the treatment effect of the prevention and treatment instrument for deep venous thrombosis can be effectively improved.
Referring to fig. 1, fig. 1 is a schematic structural view of the prevention and treatment apparatus for deep venous thrombosis provided by the present invention.
This embodiment provides a prevention and cure appearance of deep vein thrombosis, includes: a plurality of mutually independent air bags 1, a sheath 2 for installing the air bags 1, a pressure measuring device for detecting the pressure of each air bag 1, a pulse detecting device for acquiring the time length and the intensity of systole and diastole, an inflation and deflation device for inflating and deflating each air bag 1 and a control device 3; each air bag 1 is internally provided with a pressure measuring device, each air bag 1 is connected with an inflation and deflation device, and the pulse detecting device, the pressure measuring device and the inflation and deflation device are connected with the control device 3; the control device 3 is used for controlling the air inflation and deflation device to deflate when the heart contracts and inflate when the heart relaxes so as to enable each air bag 1 to reach the preset pressure.
It should be noted that the inflation and deflation rhythm of the air bag 1 by the inflation and deflation device is consistent with the diastole and contraction rhythm of the heart, and provides a promoting force for diastole and contraction of the heart, so that blood can better reach the end of the limb, and meanwhile, the air bag 1 can better promote the blood backflow of the human body when being inflated, thereby achieving the function of preventing thrombus.
In the actual application process, the shapes, structures, sizes, materials, positions and the like of the airbag 1, the sheath 2, the pressure measuring device, the pulse detecting device, the inflation and deflation device and the control device 3 can be determined according to actual conditions and actual requirements.
When the instrument for preventing deep venous thrombosis provided by the invention is used, the pulse detection device can detect the pulse of a patient in real time so as to further obtain the systole and diastole time of the patient, the control device 3 can control the inflation and deflation device to perform deflation operation when the heart contracts so as to enable the air bag 1 to perform pressure relief operation, and the control device 3 can control the inflation and deflation device to perform inflation operation when the heart relaxes so as to enable the air bag 1 to perform inflation operation. When the pulse detection device detects that the pulse intensity is strong, the control device 3 can increase the preset pressure of the air bag 1. Because the whole treatment process is carried out dynamically and all parameters are adjusted in real time, the effect of blood backflow is greatly enhanced, and the formation of thrombus is effectively prevented. The inflation and deflation rhythm of the air bag 1 of the device is consistent with the diastole and contraction rhythm of the heart, and can provide a promoting force for diastole and contraction of the heart, so that blood can better reach the tail end of the limb.
In conclusion, the prevention and treatment instrument for preventing deep venous thrombosis provided by the invention has the advantages that the inflation and deflation rhythm of the air bag 1 is consistent with the diastolic and systolic rhythm of the heart, and a promoting force can be provided for diastole and systole of the heart, so that blood can better reach the tail end of a limb, and the treatment effect of the prevention and treatment instrument for preventing deep venous thrombosis can be effectively improved.
In addition to the above-described embodiments, it is preferable that a plurality of airbags 1 are provided inside the sheath 2 from the top to the bottom, and the pulse detector is connected to the airbag 1 at the proximal end. The uppermost balloon 1 may be defined as a proximal balloon 1, the lowermost balloon 1 may be defined as a distal balloon 1, and the pulse detection device may be connected to the proximal balloon 1 for better detecting the frequency and intensity of the pulse.
It should be noted that the pulse detection device can accurately detect the frequency and intensity of the human pulse when the proximal end of the air bag 1 is pressurized to a state that the limbs are not obviously pressed. When the device is started to enter a treatment state, the pulse detection device can detect the pulse frequency of the pulse to obtain the heartbeat cycle, wherein the heartbeat cycle refers to the process from the start of one heartbeat to the start of the next heartbeat, and the process of the cardiovascular system is that each contraction and relaxation of the heart forms a cardiac cycle. When the heart is contracted once, the pulse appears once, and then the inflation and deflation operation can be carried out according to the cardiac cycle.
It should be noted that the pulse detecting device is configured to apply pressure to the proximal air cell 1 until no significant pressure is exerted on the limb (as shown by tests, when the pressure is applied to the limb to 8.5Kpa, the limb has no significant pressure and the pulse can be detected), and at the same time, the pressure measuring device is configured to detect the pressure change to calculate the frequency and intensity of the pulse.
Preferably, the preset pressure of each balloon 1 decreases from the distal end to the proximal end in sequence and is distributed in a gradient manner. The preset pressure of each air bag 1 is distributed in a gradient mode, which means that the pressure of the preset pressure of each air bag 1 is gradually reduced from the far end to the near end. The last inflation time can be calculated by the pulse detection device to determine the current inflation time.
Preferably, the single air bag inflation and deflation time period is the single air bag capacity/the total air bag capacity and the total inflation and deflation time period. Specifically, all the air bag capacities can be added to obtain the total air bag capacity, and the single air bag inflating and deflating time length is equal to the single air bag capacity/the total air bag capacity. When the air bag 1 is inflated, the air pressure of the air storage device can be adjusted in real time to ensure that the inflation operation is completed within a specified time. If the previous inflation pressure does not reach the preset pressure, the inflation pressure of the air storage device needs to be increased, because the inflation time is fixed, the pressure of the inflated airbag 1 can be increased along with the increase of the inflation pressure. If the last inflation pressure exceeds the set pressure, the inflation pressure of the gas storage device needs to be reduced, because the inflation time is fixed, and as the inflation pressure is reduced, the pressure of the inflated airbag 1 can be reduced to maintain the pressure in the airbag 1 within the preset pressure value range. The pulse detection device can detect and calculate the diastole and the systole of the first two times so as to estimate the diastole and the systole of the current time.
Preferably, the left and right ends of the sheath 2 are provided with adhesive portions that can be bonded together in a fitting manner. When the user needs to wear the sheath 2, the left and right ends of the sheath 2 may be fixed by the adhesive portions, for example, the adhesive portions may be provided on the side contacting the leg of the user and the side away from the leg of the user, respectively.
Preferably, each air bag 1 is provided with an interface connected with the air pipe 4, one end of the air pipe 4 is connected with the interface, and the other end of the air pipe 4 is connected with the inflation and deflation device. For example, an interface may be provided on a side of each airbag 1 away from the leg, the airbag 1 may be connected to a male plug 5 through the interface and the air tube 4, the male plug 5 is connected to a female plug 6 of the control device 3, and the control device 3 is connected to the inflation and deflation device, so that the inflation and deflation device effectively controls the airbag 1 to perform inflation and deflation operations.
Preferably, the inflation and deflation device comprises a control valve, a gas storage device and a gas pump for inflating and deflating the gas storage device, the gas pump is connected with the gas storage device, each gas pipe 4 is electrically connected with the gas storage device through the control valve, and the control valve is connected with the control device 3.
It should be noted that, a gas storage device may be disposed inside the control device 3, and the pressure of the gas storage device is much greater than the preset pressure of the air bag 1, when the air bag 1 needs to be inflated, the gas storage device may rapidly inflate the air bag 1 to the set pressure within the diastole time, so as to meet the requirement of rapid inflation and deflation of the air bag 1, and ensure that the inflation and deflation rhythm of the air bag 1 is consistent with the diastolic contraction rhythm of the heart.
It should be noted that when the heart contracts at the pulse moment and pumps blood to the artery, the air storage device and the air pump can control the air bags 1 to deflate, wherein deflation refers to the complete deflation of all the air bags 1, and the deflation time is the previous systole time, during which the air can be rapidly discharged out of the air bags 1 by the air pump to draw air outwards. The deflation speed of the air bag 1 can be controlled by adjusting the air pumping speed of the air pump, and the inflation and deflation speed can be adjusted in a self-adaptive mode.
For example: the pumping power of the air pump for the first deflation can be used as a test basis to measure a certain conventional value (i.e. the pulse frequency and the pulse intensity of a plurality of normal persons can be tested to obtain the required data). If the deflation time is reached and the air pressure in the air bag 1 is not 0, the air pumping power of the air pump needs to be increased when the next deflation is carried out until the air in the air bag 1 can be completely exhausted within the deflation time, so that the blood reaches the tail end of the limb.
The specific deflation time accounts for the proportion of the whole period, an empirical value can be obtained through testing a large number of people, when the heart is in diastole, the vena cava blood flows back, at the moment, the air bags 1 can be inflated, the set pressure of the air bags 1 is sequentially reduced from the far center end to the near center end, so that the set pressure of each air bag 1 is distributed in a gradient form, all the air bags 1 are inflated to the preset pressure, and the backflow of the venous blood is effectively promoted. The whole process can be quickly finished within a set time, and the whole inflation and deflation process is ensured to be consistent with the diastolic and systolic action rhythm of the heart.
Preferably, the control valve comprises a first electromagnetic valve and a second electromagnetic valve, the first electromagnetic valve and the second electromagnetic valve are three-way valves, the common end of the first electromagnetic valve is communicated with the airbag 1, one end of the first electromagnetic valve is suspended and communicated with the outside, the other end of the first electromagnetic valve is communicated with the common end of the second electromagnetic valve, one end of the second electromagnetic valve is sealed, and the other end of the second electromagnetic valve is communicated with the gas storage device.
It should be noted that, when the airbag 1 needs to be controlled to inflate, the common end of the first electromagnetic valve may be controlled to be communicated with the common end of the second electromagnetic valve, and the common end of the second electromagnetic valve is communicated with the gas storage device, so that the gas storage device is communicated with the airbag 1, and then the inflation operation is performed. When the air bag 1 needs to be controlled to deflate, the first electromagnetic valve can be controlled to be communicated with the atmosphere to deflate, and meanwhile, the public end of the second electromagnetic valve is communicated with the sealing end of the second electromagnetic valve. The air storage device is communicated with the air pump, when the pressure in the air storage device is smaller than a certain set value (the pressure of the air storage device is far larger than the preset pressure value of the air bag 1 so as to ensure that the air bag 1 can be filled to the preset pressure value in the diastole time period), the air pump can perform air filling and air discharging operation on the air storage device under the control of the control device 3, and then the air storage device is used for performing air filling and air discharging operation on the air bag 1.
When the prevention and treatment instrument for preventing deep venous thrombosis provided by the invention is used, the real-time frequency and the intensity of the pulse can be acquired in a manner of pressurizing the limbs, so that the pressure of the air bag 1 can be adjusted in real time. When the pulse intensity is stronger, the pressure of the air bag 1 can be properly increased within a proper pressure range, the whole treatment process is dynamically carried out, and all parameters can be adjusted in real time, so that the effect of blood backflow is greatly enhanced, and the formation of thrombus is effectively prevented. For example, the air bags 1 can be controlled to sequentially inflate or deflate the air bags 1 during diastole or systole according to the sequence from the far end to the near end so as to adjust the pressure of the air bags 1 in real time, so that the whole treatment process is dynamically carried out, and various parameters are adjusted in real time, thereby ensuring that the effect of blood backflow is effectively enhanced, and preventing the formation of thrombus.
In order to further explain the using method of the prevention and treatment instrument for deep vein thrombosis provided by the invention, the following description is given by way of example.
Firstly, the proximal air bag 1 can be inflated by the air pump and the air storage device, and when the proximal air bag 1 is pressurized to 8KAP and no obvious compression feeling is caused to the limb, the pulse detection device can detect the frequency and the intensity of the pulse. For example, the pulse intensity can be obtained by detecting the fluctuation rate of the real-time pressure in the air bag 1, if the pulse is strong, the change of the extrusion force on the air bag 1 in the pulse beating period is large, and if the pulse is weak, the change of the extrusion force on the air bag 1 in the pulse beating period is small.
Then, the pulse detection device can measure the frequency and intensity of the last pulse, and calculate the contraction and relaxation time of the heart, when the heart contracts, the control device 3 can control the air bag 1 to deflate, when the heart contracts, the vena cava blood reflows, and the air bag 1 is rapidly inflated from the far end to the near end in sequence to reach the preset pressure of the air bag 1. The pulse detection device can estimate the diastolic time of the current time through the fluctuation period of the last pulse and the time distribution of diastolic contraction, and meanwhile, the control device 3 can sequentially inflate the air bags 1 from the far end to the near end during diastole, namely sequentially inflate the first cavity, the second cavity, the third cavity and the fourth cavity from the far end. When the heart contracts, the air bags 1 are controlled to be deflated simultaneously.
The pulse detection device can also determine the current inflation time according to the last inflation time, namely the inflation time of a single air bag 1 is equal to the total inflation time of the single air bag volume/the total air bag volume; the air pressure in the air storage device can be adjusted in real time when the air bag 1 is inflated, so that the inflation operation can be completed within a specified time. If the previous inflation pressure does not reach the set value, the air pressure in the air storage device is increased, and if the previous inflation pressure exceeds the set pressure, the inflation pressure in the air storage device is decreased, thereby maintaining the pressure in the airbag 1 at the set value. Meanwhile, the control device 3 can adjust the pressure of the air bag 1 according to the intensity of the pulse, and the stronger the pulse is, the greater the pressure of the air bag 1 is. The pulse intensity of the human body is detected by the pulse detection device, and the pulse intensity can be divided into three levels. The stronger the pulse intensity, the larger the corresponding pressure level, the stronger the pulse intensity can reflect the activity of the heart and blood vessels to prevent the damage to the blood vessels and promote the blood backflow. Taking the four-chamber sheath 2 as an example, the pressure rating distribution of the corresponding balloon 1 is as follows:
first-stage: 100. 80, 60, 40 (unit: mm Hg);
and (2) second stage: 120. 100, 80, 60 (unit: mm Hg);
third-stage: 140. 120, 100, 80 (unit: mm Hg);
then, the pulse detection device calculates the systolic and diastolic time, when the heart contracts, the heart pumps blood to the artery, and at this time, the control balloon 1 is deflated, wherein if the systolic time is short, the gas during the systole cannot be exhausted, and therefore, the gas needs to be pumped out by the gas pump. If the air can not be exhausted, the air can be exhausted by the air pump in the control device 3 because the air-bleeding time is short, so that the air can be exhausted quickly. The air discharge speed of the air bag 1 can be controlled by adjusting the air discharge speed of the air pump, and is adjusted in a self-adaptive mode.
Finally, the operation can be stopped in the pulse interval, and when the pulse beats, the operation can be returned to the step of acquiring the beating time length and the beating intensity of the heart in the contraction and relaxation states until the treatment time is finished; or directly jumping back to the step of acquiring the beating time length and the beating intensity of the heart in the contraction and relaxation states until the treatment time is over.
