Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an adaptive balloon dilation pressure pump. Background Art

[0002] Interventional surgery plays an important role in medical treatment. As one of the common methods of interventional treatment, balloon dilation usually uses a pressure pump to inject normal saline mixed with contrast agent into the balloon to expand it and make it visible at the same time. There are two key parameters in the balloon dilation process: the standard pressure and the burst pressure. The standard pressure is the dilation pressure to reach the balloon diameter, and the burst pressure is the limit of balloon dilation. When pressurizing the pressure pump, it needs to be controlled between the two. Different professional surgeries have different requirements for the speed of the injection pressure pump, such as slow dilation and slow withdrawal, slow dilation and fast withdrawal, fast dilation and fast withdrawal, etc. However, the existing pressure pumps are all manually controlled by the operator's experience and cannot accurately meet these requirements.

[0003] Taking the existing mechanical pressure pump as an example, it consists of a pressure gauge, a pressurizing handle, a graduated syringe, and a hose connected to the balloon. When a doctor performs a balloon dilation operation, first close the bayonet on the pressurizing handle and quickly pull the handle backward to fill the syringe with contrast agent, then connect the hose to the balloon and quickly push the contrast agent into the balloon to fill it. When the value on the pressure gauge is greater than 0, release the bayonet and turn the pressurizing handle towards the balloon side to slowly pressurize to the target working pressure. After the balloon reaches the target working pressure, it is necessary to observe the working state of the balloon and the value on the pressure gauge at the same time. When the pressure drops, manually pressurize to maintain it. After the pressure holding time ends, turn the pressurizing handle towards the side away from the balloon to release the pressure. When the value on the pressure gauge is 0, close the bayonet and quickly pull back the pressurizing handle to retract the balloon.

[0004] The existing mechanical pressure pump has obvious disadvantages. One is that it cannot achieve precise control of pressure. The other is that during the operation, the balloon pressure will be lower than the required value and the doctor needs to observe the pressure gauge and manually pressurize at any time. This not only increases the operation burden of the doctor, but also may affect the operation effect due to the inability to accurately control the pressure. Summary of the Invention

The piezoelectric pressure sensor faces the measurement hole and closes the measurement hole. The piezoelectric pressure sensor is used to measure the pressure inside the syringe;

[0014] A displacement sensor, which is fixedly connected to the push rod;

[0015] A data processing and signal amplification module. The piezoelectric pressure sensor and the displacement sensor are respectively connected to the input end of the data processing and signal amplification module. The output end of the data processing and signal amplification module is signal-connected to the linear driving device;

[0016] A programmable touch screen, which is signal-connected to the data processing and signal amplification module;

[0017] A power supply, which is used to supply power to the linear driving device, the piezoelectric pressure sensor, the displacement sensor, the data processing and signal amplification module and the programmable touch screen.

[0018] Preferably, the linear driving device adopts a servo electric cylinder.

[0019] Preferably, it further includes a box body. The cylinder body of the linear driving device, the power supply and the data processing and signal amplification module are all arranged in the box body;

[0020] A first support frame and a second support frame are arranged in the box body.

One end of the linear driving device is fixedly connected to the second support frame.

[0021] Preferably, it further includes a top cover, and a handle is arranged on the top cover;

[0023] Preferably, the programmable touch screen is located outside the box body and fixedly connected to the outer wall of the box body.

[0024] Preferably, the push rod is located outside the box body.

[0025] Preferably, it further includes a support block, one end of the support block is fixedly connected to the box body;

[0026] The support block includes a convex part and a concave part, the concave part is closer to the box body than the convex part; an annular limiting piece is fixedly sleeved on the syringe barrel, a groove with a semicircular cross-section that matches the barrel of the syringe is arranged on the top surface of the convex part, the barrel of the syringe is placed on the groove, and the annular limiting piece is used to abut against one end of the convex part close to the concave part.

[0027] Preferably, the groove, the syringe barrel, the push rod and the output end of the linear driving device are coaxial.

[0028] Preferably, the rubber plug is bonded to the push rod through epoxy resin glue; the piezoelectric pressure sensor is hermetically bonded to the syringe barrel through epoxy resin glue; the hose is bonded to the liquid passage hole of the syringe barrel through epoxy resin glue.

[0029] Preferably, the test hole is close to the liquid passage hole.

[0030] The present invention has achieved the following technical effects compared with the prior art:

[0031] The adaptive balloon dilation pressure pump of the present invention solves the problem that the existing mechanical pressure pump cannot achieve precise pressure control. Through a system composed of a programmable touch screen, a data processing and signal amplification module, a servo electric cylinder, a displacement sensor, a piezoelectric pressure sensor, etc., the linear displacement of the servo electric cylinder can be linearly processed with the balloon pressure value to achieve precise control of the balloon pressure. For example, complex pressure control requirements such as requiring the balloon to slowly expand for 60 seconds to reach the standard pressure, maintain for 180 seconds, and the balloon to be completely evacuated within 30 seconds can be met.

[0032] Furthermore, it overcomes the problem that the existing pressure pump cannot maintain the pressure after the balloon expands to the standard pressure and the pressure will drop and cannot reach the required pressure value. When the actual pressure value is less than the target pressure value, the programmable touch screen outputs a corresponding voltage signal, and through the data processing and signal amplification module, the servo electric cylinder is driven to push the push rod to pressurize the balloon to keep the pressure of the balloon maintained at the target pressure value.

[0033] Furthermore, when performing balloon dilation surgery, doctors do not need to, like when using existing mechanical pressure pumps, pay attention to the balloon dilation status on the interventional surgery screen while repeatedly looking down at the pressure value on the pressure gauge of the pressure pump, thus avoiding possible pressure fluctuations. At the same time, doctors only need to input parameters such as pressurization time, target pressure value, pressure holding time, and pressure relief time in the interface of the upper computer, and the pressure value of the balloon during the subsequent surgical process does not require doctor intervention, saving the doctor's energy and physical strength and improving the safety of balloon dilation surgery.

[0034] Furthermore, compared with existing mechanical pressure pumps, the pressure detection servo system can achieve more precise pressure control and automatic pressure holding. Under the control of the data processing and signal amplification module and the programmable touch screen, the servo electric cylinder can automatically adjust the pressurization intensity according to the actual pressure of the balloon, improving the accuracy and stability of pressure control.

[0035] Furthermore, the adaptive balloon dilation pressure pump can be adapted to various types of balloons, expanding the application range of the pressure pump. By collecting the displacement values when the balloon pressure is 0, standard pressure, and burst pressure during the calibration stage, and linearly processing the above displacement values through the software built in the programmable touch screen, precise pressure control for different types of balloons is ensured.

[0036] Furthermore, the adaptive balloon dilation pressure pump of the present invention has the advantages of precise pressure control, automatic pressure holding, improving surgical safety and convenience. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0046] The purpose of the present invention is to provide an adaptive balloon dilation pressure pump to solve the problems existing in the above-mentioned prior art and achieve precise control of the balloon dilation pressure.

[0047] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0048] As Figures 1 to 5 shown, this embodiment provides an adaptive balloon dilation pressure pump 100, including:

[0049] A fixedly arranged linear drive device 8;

[0050] A push rod 10, one end of the push rod 10 is fixedly connected to the output end of the linear drive device 8;

[0051] A fixedly arranged syringe 13, one end of the syringe 13 is provided with a liquid through hole 22;

[0052] A rubber plug 11, the rubber plug 11 is fixedly connected to the other end of the push rod 10, the outer wall of the rubber plug 11 is in close fit with the inner wall of the syringe 13, and the rubber plug 11 can slide relative to the syringe 13;

[0053] A hose 14, one end of the hose 14 is communicated with the liquid through hole 22, and the other end of the hose 14 is used to communicate with the balloon to be used;

[0054] The piezoelectric pressure sensor 12 is arranged on the syringe 13. The syringe 13 is provided with a measurement hole corresponding to the piezoelectric pressure sensor 12. The piezoelectric pressure sensor 12 faces the measurement hole and closes the measurement hole. The piezoelectric pressure sensor 12 is used to measure the pressure inside the syringe 13;

[0055] The displacement sensor 9 is fixedly connected to the push rod 10;

[0056] The data processing and signal amplification module 5. The piezoelectric pressure sensor 12 and the displacement sensor 9 are respectively connected to the input end of the data processing and signal amplification module 5. The output end of the data processing and signal amplification module 5 is signal-connected to the linear drive device 8;

[0057] The programmable touch screen 1 is signal-connected to the data processing and signal amplification module 5;

[0058] The power supply 4 is used to supply power to the linear drive device 8, the piezoelectric pressure sensor 12, the displacement sensor 9, the data processing and signal amplification module 5 and the programmable touch screen 1.

[0059] The specific usage method of the adaptive balloon dilation pressure pump 100 in this embodiment is as follows:

[0060] (1) Calibration stage

[0061] Place the entire adaptive balloon dilation pressure pump 100 on a flat workbench. Connect the hose 14 to the balloon to be used. At this time, the balloon is filled with normal saline mixed with contrast agent and the pressure of the balloon is 0; input the standard pressure value and burst pressure value of balloon dilation through the programmable touch screen 1, and then push the push rod 10 through the linear drive device 8, thereby driving the rubber plug 11 to move inside the syringe 13 to pressurize the balloon;

[0062] During the pressurization process, the displacement sensor 9 respectively collects the displacement values when the balloon pressure is 0, the standard pressure, and the burst pressure;

[0063] The collected displacement values are input into the preset software of the programmable touch screen 1 through A / D conversion by the data processing and signal amplification module 5; after being processed by the preset software, the linear displacement of the linear drive device 8 and the balloon pressure value are linearly processed to realize the calibration work of the output displacement value of the linear drive device 8 and the balloon pressure value, and prepare for the subsequent precise control of the balloon pressure;

[0064] It should be noted that the above-mentioned preset software can be written by technicians based on existing programming knowledge and the content disclosed in this embodiment. In this embodiment, the above-mentioned preset software will not be elaborated further;

[0065] (2) Actual working stage

[0066] Connect the balloon and the pressure pump that are the same as those in the calibration stage;

[0067] The doctor inputs parameters such as pressurization time, target pressure value, pressure holding time, pressure relief time, etc. in the software interface of the programmable touch screen 1, and then clicks the start button;

[0068] Pressurization process: The pressure pump pressurizes the balloon according to the set pressurization time; during this process, the linear drive device 8 pushes the push rod 10 according to the instructions of the programmable touch screen 1, causing the rubber plug 11 to move in the syringe 13, and pushing the physiological saline mixed with the contrast agent into the balloon, thereby increasing the pressure inside the balloon;

[0069] Pressure monitoring and adjustment: The piezoelectric pressure sensor 12 collects the balloon pressure value in real time. When the pressure reaches the target pressure value, the collected pressure value is input into the software of the programmable touch screen 1 through the data processing and signal amplification module 5; the software in the programmable touch screen 1 compares the actually collected balloon pressure value with the target pressure value set by the doctor. When the actual pressure value is less than the target pressure value, the programmable touch screen 1 outputs a corresponding voltage signal to drive the linear drive device 8 through the data processing and signal amplification module 5 to push the push rod 10 to pressurize the balloon, so as to keep the pressure of the balloon maintained at the target pressure value until the actual pressure value is equal to the target pressure value;

[0070] Pressure holding: During the pressure holding period, the piezoelectric pressure sensor 12 continuously monitors the balloon pressure, and the linear drive device 8 automatically adjusts the output force as needed to ensure that the balloon pressure is stable at the target value;

[0071] Pressure relief process: When pressure relief is required, the linear drive device 8 pulls the push rod 10 according to the instructions of the programmable touch screen 1, causing the rubber plug 11 to move in the syringe 13 in the reverse direction, and extracting the contrast agent in the balloon to reduce the pressure inside the balloon;

[0072] During the entire working process, the programmable touch screen 1, the data processing and signal amplification module 5, the linear drive device 8, the displacement sensor 9, and the piezoelectric pressure sensor 12 are all powered by a lithium battery; each component works together to achieve precise control and real-time control of the balloon pressure, improving the safety and convenience of balloon dilation surgery.

[0073] In an alternative embodiment of the present embodiment, preferably, the linear drive device 8 is a servo electric cylinder; the servo electric cylinder can achieve precise position control and can accurately push the push rod 10 to move a specific distance according to preset parameters. In the balloon expansion pressure pump, this means that the position of the rubber plug 11 in the syringe 13 can be precisely controlled, thereby precisely controlling the pressure inside the balloon. For example, in a surgery where the balloon is required to slowly expand to a specific pressure value, the servo electric cylinder can push the push rod 10 in very small steps to ensure a precise increase in pressure; the servo electric cylinder can adjust the moving speed of the push rod 10 according to different surgical requirements. Some surgeries require slow expansion and slow withdrawal, while some require fast expansion and fast withdrawal, and the servo electric cylinder can meet these different speed requirements. By setting different speed parameters through the programmable touch screen 1, the servo electric cylinder can precisely control the moving speed of the push rod 10, thereby achieving precise control of the balloon expansion and withdrawal speeds.

[0074] It should be noted that in practical applications, the linear drive device 8 can be replaced with other precision drive components such as a linear motor. The linear motor has the advantages of fast response speed, high precision, and no wear, which may bring further improvement in the accuracy and response speed of pressure control. The data processing device composed of the data processing and signal amplification module 5 and the programmable touch screen 1 can also be replaced with a scheme of PLC and touch screen. The PLC has the characteristics of high reliability and flexible programming, and can achieve similar pressure control functions when paired with the touch screen. This alternative scheme may have advantages in terms of system stability and scalability.

[0075] Specific description of other structures of the adaptive balloon expansion pressure pump 100 of the present embodiment:

[0076] The adaptive balloon expansion pressure pump 100 of the present embodiment further includes a box body 16 and a top cover 7. The cylinder body of the linear drive device 8, the power supply 4, and the data processing and signal amplification module 5 are all arranged inside the box body 16;

[0077] A first support frame 2 and a second support frame 6 are arranged inside the box body 16. The power supply 4 and the data processing and signal amplification module 5 are respectively connected to the first support frame 2 by bolts, and one end of the linear drive device 8 is fixedly connected to the second support frame 6;

[0078] A handle 17 is arranged on the top cover 7; the top side of the box body 16 is open and a U-shaped groove is provided corresponding to the top cover 7, and the top cover 7 can be inserted into the U-shaped groove; the top cover 7 is in sliding fit with the U-shaped groove; an end plate 3 is also detachably connected to the box body 16, and the end plate 3 is drawn out from one end of the box body 16 where the top cover 7 is located; the end plate 3 plays a limiting role on the top cover 7, and the end plate 3 is connected to the box body 16 by a plurality of bolts. Only when the end plate 3 is removed from the box body 16 can the top cover 7 be drawn out from the U-shaped groove.

[0079] The programmable touch screen 1 is located outside the box body 16 and fixedly connected to the outer wall of the box body 16; the push rod 10 is located outside the box body 16; in this embodiment, the power supply 4 preferably uses a lithium battery.

[0080] In an alternative embodiment of the present embodiment, more preferably, it further includes a support block 15, one end of the support block 15 is fixedly connected to the box body 16;

[0081] The support block 15 includes a convex portion 19 and a concave portion 20, the concave portion 20 is closer to the box body 16 than the convex portion 19; an annular limiting piece 18 is fixedly sleeved on the syringe barrel 13, and the top surface of the convex portion 19 is provided with a groove with a semi-circular cross-section that matches the barrel of the syringe barrel 13, and the barrel of the syringe barrel 13 is placed on the groove, and the annular limiting piece 18 is used to abut against one end of the convex portion 19 close to the concave portion 20; enabling the annular limiting piece 18 to abut against one end of the convex portion 19 close to the concave portion 20 can fix the position of the syringe barrel 13 and maintain the stability of the position of the syringe barrel 13, thereby ensuring the stability of the pressurization process by driving the rubber plug 11 to move.

[0082] In an alternative embodiment of the present embodiment, more preferably, the groove, the syringe barrel 13, the push rod 10 and the output end of the linear driving device 8 are coaxial, ensuring that the force generated by the linear driving device 8 can be transmitted to the push rod 10 along a straight line without deviation, and then the push rod 10 pushes the rubber plug 11 to move in the syringe barrel 13. This way of transmitting the linear force ensures the accuracy of the pressure application, avoids the component force or offset force caused by non-coaxiality, and thus can more precisely control the pressure in the syringe barrel 13, and further accurately control the pressure of the balloon connected to the syringe barrel 13.

[0083] In an alternative embodiment of the present embodiment, more preferably, the rubber plug 11 is adhesively bonded to the push rod 10 with epoxy resin glue; the piezoelectric pressure sensor 12 is hermetically adhesively bonded to the syringe barrel 13 with epoxy resin glue; the hose 14 is adhesively bonded to the liquid passage hole 22 of the syringe barrel 13 with epoxy resin glue.

[0084] In an alternative embodiment of the present embodiment, more preferably, the test hole 21 is close to the liquid passage hole 22; having the test hole 21 close to the liquid passage hole 22 has at least the following advantages:

[0085] The liquid passage hole 22 is the part connected to the hose 14 and is also the inlet for the liquid pressure in the balloon to be transmitted into the syringe barrel 13. Setting the test hole 21 close to the liquid passage hole 22 can be closer to the pressure source, reduce the loss and fluctuation of the pressure during the transmission process, thereby more accurately measuring the actual pressure in the syringe barrel 13, and further more truly reflecting the pressure situation in the balloon;

[0086] Due to being close to the pressure source, when the pressure inside the balloon changes, the piezoelectric pressure sensor 12 can sense the pressure change more quickly and transmit the signal to the data processing and signal amplification module 5. This helps to achieve real-time monitoring and precise control of the balloon pressure. Especially in surgical scenarios that require rapid response, such as rapid dilation or rapid retraction, it can timely adjust the output of the linear drive device 8 to ensure that the balloon pressure is always within the range of safe and precise control.

[0087] During the calibration phase, placing the piezoelectric pressure sensor 12 close to the liquid passage hole 22 can make the measured pressure value closer to the actual pressure of the balloon, thus making it easier to perform system linearization processing and calibration. This helps to improve the accuracy and performance of the entire adaptive balloon dilation pressure pump 100, ensuring that the balloon can be pressurized and controlled accurately according to the parameters set by the doctor during the actual working phase.

[0088] In addition, since the rubber plug 11 and the syringe barrel 13 are in sliding fit, during the pressurization process, the rubber plug 11 usually slides from one end of the syringe barrel 13 away from the liquid passage hole 22 to the other end, causing the test hole 21 to approach the liquid passage hole 22, which can avoid the situation where the rubber plug 11 obscures the test hole 21.

[0089] Furthermore, it should be noted that in practical applications, the push rod 10, rubber plug 11, piezoelectric pressure sensor 12, syringe barrel 13, and hose 14 in the adaptive balloon dilation pressure pump 100 of this embodiment are all used as disposable products. For other parts except the push rod 10, rubber plug 11, piezoelectric pressure sensor 12, syringe barrel 13, and hose 14, a disposable protective cover should be sleeved before use, and after use, the push rod 10, rubber plug 11, piezoelectric pressure sensor 12, syringe barrel 13, hose 14, and the used protective cover should be treated as medical waste to avoid medical infection phenomena such as cross-infection between patients.

[0090] In the present invention, specific examples are used to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, based on the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
