A digital display balloon expansion pressure pump

[0001] Cross-references to related applications

[0002] This application claims priority to Chinese Patent Application No. 202411031357.6, filed on July 29, 2024, entitled "A Digital Display Balloon Expansion Pressure Pump", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of medical device technology, specifically to a digital display balloon expansion pressure pump. Background Technology

[0004] Balloon inflation pressure pumps are widely used in various endoscopic surgeries, angioplasty, and other medical procedures to achieve precise pressure control of the balloon.

[0005] The existing balloon inflation pressure pump mainly consists of a pump body, a mechanical pressure gauge, and connecting fasteners. The mechanical pressure gauge is mounted on the pump body via the fasteners and is used to display the pressure inside the balloon. The dial of the mechanical pressure gauge includes a pointer and a pressure scale. When the pressure inside the balloon inflation pressure pump rises, the pointer rotates clockwise, and the corresponding scale reading indicates the current pressure inside the pump.

[0006] Because mechanical pressure gauges suffer from inconvenient dial readings, poor accuracy, and lack of automatic timing, some balloon inflation pumps now use digital pressure gauges instead. Digital pressure gauges display pressure values ​​digitally, resulting in higher accuracy. However, existing digital pressure gauges only display the pressure value numerically, offering a limited and indirect display that doesn't provide the operator with a clear understanding of the balloon's inflation status.

[0007] Summary of the Invention

[0008] Therefore, the technical problem to be solved by this application is to overcome the shortcomings of the pressure gauge on the balloon expansion pressure pump in the prior art, which has a single function and a non-intuitive display effect, so as to provide a digital display balloon expansion pressure pump.

[0009] To solve the above-mentioned technical problems, the technical solution of this application is as follows:

[0010] A digital display balloon inflation pressure pump, comprising:

[0011] The pressure pump body is used to inflate the balloon.

[0012] The digital pressure gauge includes a pressure sensor for acquiring the internal pressure at the end where the pressure pump body is connected to the balloon, a controller electrically connected to the pressure sensor, and a display electrically connected to the controller.

[0013] The pressure sensor is controlled by the controller to collect pressure signals inside the pressure pump body in real time. The controller processes the pressure signals collected by the pressure sensor at various time points to form pressure-time change data. The display shows the pressure-time change curve on the screen based on the pressure-time change data.

[0014] Optionally, the display may also continuously refresh the pressure-time change curve shown on the screen according to control commands issued by the controller.

[0015] Optionally, the digital pressure gauge further includes a storage module for automatically storing the pressure-time change data.

[0016] Optionally, the digital pressure gauge further includes a data transmission module electrically connected to the storage module. The data transmission module communicates with an external device via wired or wireless transmission. The external device is used to read or export the pressure-time change data stored in the storage module.

[0017] Optionally, the data transmission module is a Bluetooth module.

[0018] Optionally, the screen of the display may also display the pressure value data collected by the pressure sensor in real time in the form of a mechanical dial.

[0019] Optionally, the digital pressure gauge further includes a timing module electrically connected to the controller; when the pressure value signal collected by the pressure sensor is greater than a preset threshold, the timing module automatically records the time point as T1; when the pressure value signal collected by the pressure sensor is equal to or less than the preset threshold, the timing module automatically records the time point as T2, and the timing module also automatically calculates the time difference between time point T2 and time point T1; the display shows the time difference on the screen.

[0020] Optionally, the digital pressure gauge also includes a battery module that provides the power required for the operation of the digital pressure gauge, and the screen of the display also displays the remaining power information and Bluetooth connection status information.

[0021] Optionally, the digital pressure gauge further includes a power on / off button, a function button, and a timing button; the power on / off button controls the opening and closing of the digital pressure gauge when pressed and held, the function button controls the backlight and function setting menu interface of the digital pressure gauge, and the timing button controls the starting, pausing, timing, and resetting of the timing function.

[0022] Optionally, the digital pressure gauge is fixed to a connecting fastener, the connecting fastener having a threaded interface, and the connecting fastener being threadedly connected to the side wall of the pressure pump body through the threaded interface; the connecting fastener has a cavity communicating with the inner cavity of the pressure pump body, and the pressure sensor of the digital pressure gauge is placed in the cavity of the connecting fastener.

[0023] The technical solution of this application has the following advantages:

[0024] 1. The digital display balloon inflation pressure pump provided in this application uses a digital pressure gauge instead of a traditional mechanical pressure gauge. The pressure sensor, controlled by a controller, can collect pressure signals from inside the pump body in real time. The controller processes the pressure signals collected by the pressure sensor at various time points to generate pressure-time change data. The display shows the pressure-time change curve on the screen based on this data. Since the digital pressure gauge displays a pressure-time change curve, the inflation status of the balloon can be understood more intuitively by observing the trend of pressure value changes in the curve. For example, when the pressure value in the pressure-time change curve increases with time, the operator can clearly know that the balloon is inflating. The operator can also observe the curvature of the pressure-time change curve to determine the inflation rate. When the curvature of the pressure-time change curve is too large, the pump speed can be reduced to prevent the balloon from inflating too quickly and causing harm to the human body, thus simplifying the operation during balloon inflation.

[0025] 2. The digital display balloon expansion pressure pump provided in this application can continuously refresh the pressure-time change curve according to the control command sent by the controller, and can present a dynamic pressure-time waveform curve on the screen, so that the operator can see the pressure change process more intuitively on the screen.

[0026] 3. The digital display balloon expansion pressure pump provided in this application uses a storage module to store pressure-time change data and uses a data transmission module to transmit the pressure-time change data to an external mobile phone or monitor via wired or wireless transmission. The monitor can analyze the pressure-time change data and objectively evaluate whether there are any operational errors by the operator during the operation.

[0027] 4. The digital display balloon expansion pressure pump provided in this application displays the pressure value in real time on the screen in addition to the pressure-time change curve, using a mechanical dial. This makes the pressure value reading more intuitive and accurate without changing the original usage habits.

[0028] 5. The digital display balloon inflation pressure pump provided in this application displays the time difference between the current time point Tn and the timing start time point T1 on the display screen. This time difference is the balloon inflation time. The inflation time is directly displayed on the display screen, which makes it easy to intuitively understand the balloon inflation time during the operation. This makes it easier for the operator to control the balloon inflation time within a reasonable range, and also makes it easier to objectively evaluate whether the balloon inflation time exceeds the standard time based on the timing data.

Detailed Implementation

[0034] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] As shown in Figures 1-2, a digital display balloon inflation pressure pump includes a pump body 1, a digital display pressure gauge 2, and a connecting fastener. The pump body 1 includes a syringe 11 and a piston 12. One end of the syringe 11 has a balloon connection end 111, which communicates with a distal balloon 4. The piston 12 is used to inflate the balloon 4 with pressure through the syringe 11. Threaded interfaces are provided on the side wall of the syringe 11 at the end connecting to the balloon 4 and on the connecting fastener. The connecting fastener is threaded onto the side wall of the syringe 11 through these interfaces. The digital display pressure gauge 2 is integrated with the connecting fastener by screws. The connecting fastener has a cavity communicating with the inner cavity of the pump body 1, and the pressure sensor 21 of the digital display pressure gauge 2 is placed within this cavity.

[0038] As shown in Figure 1-2, the digital pressure gauge 2 includes a pressure sensor 21, a controller 22, a display 23, and a storage module 24. The pressure sensor 21 is used to collect the internal pressure at the connection point between the pressure pump body 1 and the balloon 4. The display 23, pressure sensor 21, and storage module 24 are all electrically connected to the controller 22. The pressure sensor 21, controlled by the controller 22, collects the pressure value signal inside the pressure pump body 1 in real time. The controller 22 processes the pressure value signal collected by the pressure sensor 21 at various time points to form pressure-time change data. The storage module 24 automatically stores the pressure-time change data, and the display 23 shows the pressure-time change curve 23a on the screen based on the pressure-time change data.

[0039] This digital display balloon inflation pressure pump displays a pressure-time curve 23a on the screen of the digital pressure gauge 2. Operators can observe the pressure value changes in this curve to gain a more intuitive understanding of the balloon 4's inflation status. For example, when the pressure value in the pressure-time curve 23a increases over time, the operator can clearly see that the balloon 4 is inflating. The operator can also observe the curvature of the pressure-time curve 23a to determine the inflation rate of the balloon 4. If the curvature is too large, the pumping speed of the pressure pump body 1 can be reduced to prevent the balloon 4 from inflating too quickly and causing harm to the human body, thus simplifying the operation during the balloon 4 inflation process.

[0040] As shown in Figure 1-2, the display 23 continuously refreshes the pressure-time change curve 23a displayed on the screen according to the control commands issued by the controller 22; with this setting, a dynamic pressure-time waveform curve can be presented on the screen, and the operator can see the process of balloon pressure change more intuitively on the screen.

[0041] As shown in Figures 1-2, the digital pressure gauge 2 also includes a data transmission module electrically connected to the storage module 24. The data transmission module communicates with external devices (such as mobile phones or monitors) via wired or wireless transmission. The external devices are used to read or export the pressure-time change data stored in the storage module 24. Specifically, the data transmission module is a Bluetooth module 25. By using the storage module 24 to store the pressure-time change data and the data transmission module to transmit the data to an external mobile phone or monitor via wired or wireless transmission, the monitor can analyze the pressure-time change data and objectively evaluate whether the operator made any operational errors during the surgery. In an alternative implementation, the data transmission module can also be a wired transmission interface. This wired interface can communicate with other devices via a data cable, such as external temperature measurement accessories, blood pressure measurement accessories, blood oxygen measurement accessories, FFR measurement accessories, and OCT measurement accessories, and automatically switch to the corresponding display interface. This reduces the number of monitoring screens the operator needs to observe during surgery, allowing them to focus more on the current operation.

[0042] As shown in Figure 3, the pressure value data collected by the pressure sensor 21 is also displayed in real time on the screen of the display 23 in the form of a mechanical dial 23b. In addition to displaying the pressure-time change curve 23a, the screen of the display 23 also displays the pressure value in real time in the form of a mechanical dial 23b, making the pressure value reading more intuitive and accurate without changing the original usage habits.

[0043] As shown in Figures 2 and 3, the digital pressure gauge 2 also includes a timing module 26 electrically connected to the controller 22. When the pressure signal collected by the pressure sensor 21 is greater than a preset threshold, the timing module 26 automatically records the time point as T1; when the pressure signal collected by the pressure sensor 21 is equal to or less than the preset threshold, the timing module 26 automatically records the time point as T2. The timing module 26 also automatically calculates the time difference between time point T2 and time point T1. The display 23 shows the time difference on the screen, which is the inflation time of the balloon 4. The display of the inflation time on the screen of the display 23 makes it easy to intuitively understand the inflation time of the balloon 4 during the operation, which helps the operator control the inflation time of the balloon 4 within a reasonable range, and also facilitates subsequent objective evaluation of whether the inflation time of the balloon 4 exceeds the standard time based on the timing data.

[0044] As shown in Figure 3, the digital pressure gauge 2 also includes a battery module 27 that provides the power required for its operation. The screen of the display 23 also displays the remaining battery power and Bluetooth connection status. The digital pressure gauge 2 also includes a power button, a function button, and a timing button. The power button, when pressed and held, controls the digital pressure gauge 2 to turn on and off. The function button controls the backlight and the function setting menu interface of the digital pressure gauge 2. The timing button controls the timing function to start, pause, start, and reset.

[0045] Specifically, to power on the device, press and hold the power button for more than 3 seconds while it is off; to power off the device, press and hold the power button for more than 5 seconds while it is on. The first short press of the function button illuminates the backlight; the second short press opens the function settings menu, allowing functions such as connecting to Bluetooth, switching interfaces, switching units, and resetting data. The first short press of the timer button starts the timer; the second short press pauses the timer; the third short press displays the time; and a long press resets the timer and starts a new one. When the function settings menu is displayed, a short press of the power button moves the load upwards to search for timing data, a short press moves the timer downwards, a double-click of the function button goes back, and a long press returns to the working interface.

[0046] Specifically, the digital pressure gauge 2 has a pressure display resolution of 0.1 ATM / 1 PSI, a pressure monitoring accuracy of no more than 2% FS, and a drift of no more than 1% within 3 years. The time display resolution is 1 second. The digital pressure gauge 2 has a pressure-time waveform display function, and when used with a specific balloon 4, it can display the expansion status of the balloon 4 in the patient's blood vessels in real time. The digital pressure gauge 2 has a built-in storage module that can store more than 10 hours of pressure and time data, and a Bluetooth module 25 that can connect to a mobile phone or other monitoring equipment to view real-time data, pressure-time waveforms, and query historical data. It can also be connected to monitoring equipment to display pressure data and other patient physiological indicators on the same interface for easy observation by the operator.

[0047] In summary, the digital display balloon expansion pressure pump provided in this application has the following advantages: it uses a digital pressure gauge 2 instead of a traditional mechanical pressure gauge, and the pressure value is displayed in both mechanical dial style and digital form, making the pressure value reading more intuitive and accurate without changing the original usage habits. Due to the characteristics of the pressure sensor 21, it offers higher accuracy and is less affected by environmental factors compared to traditional mechanical pressure gauges, with minimal accuracy drift even after long-term storage. The timing function automatically starts and stops timing upon pressure detection, or the operator can manually start and stop it, reducing operator workload and providing more functional options. The integrated pressure-time waveform display simplifies the monitoring process during surgery. The backlight function automatically illuminates upon pressure detection or can be manually activated by the operator for easy observation in low-light environments. Pressure timing data is automatically stored in the internal storage module and can be exported via wired transmission or connected to a mobile phone or monitor via the built-in Bluetooth module 25 for real-time monitoring of pressure changes. It can also be used with external accessories such as body temperature measurement, blood pressure measurement, blood oxygen measurement, FFR measurement, and OCT measurement, automatically switching to the corresponding display interface. It boasts advantages such as ease of operation, intuitive readings, aesthetically pleasing appearance, waterproof design, and convenient data management and analysis, while also further enhancing surgical safety.

[0048] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
