Description

Technical Field

[0001] The present application relates to the field of medical device technology, and more specifically, to a readable storage medium and a balloon pressure system. Background Art

[0002] A balloon pressure pump is a common medical device that is used to pressurize a balloon so that the balloon is inflated and expanded to a set size, thereby stretching the stenosis to facilitate the operator to treat the stenosis. After the balloon expansion is completed, the operator pulls back the pressure pump handle, and the pressure in the balloon is released to form a negative pressure, which reduces the size of the balloon so that it can be withdrawn.

[0003] Currently, the common operation mode of balloon pressure pumps on the market is manual operation. During the use of the balloon pressure pump, the push rod is pulled or squeezed with both / one hands to pressurize, release pressure, and draw negative pressure in the cavity of the cylinder to expand or shrink the balloon. However, manual operation is not convenient and is time-consuming and labor-intensive. At the same time, since the operator cannot directly observe the size changes of the balloon, the operator can only judge whether the balloon is inflated and expanded to the target size based on the operator's experience during the balloon pressurization process. Therefore, the size of the balloon may be too small to fully open the stenosis or too large to cause damage. Summary of the invention

[0004] The embodiments of the present application aim to solve the problem that the balloon pressure pump in the prior art can only pressurize, relieve pressure, and draw negative pressure to the cavity of the cylinder by manually pulling or squeezing the push rod, which is inconvenient and time-consuming and labor-intensive. In addition, due to the operator's lack of experience, the balloon may not reach the set size, thereby failing to open the stenosis or causing damage to the stenosis.

[0005] In order to solve the above technical problems, the embodiment of the present application provides a readable storage medium, which adopts the following technical solution:

[0016] in, is the first set pressure value after correction, is the preset first set pressure value, is the preset third set pressure value, and n is the number of pressure corrections;

[0017] The corrected first set pressure value replaces the original first set pressure value.

[0018] Furthermore, before the step of replacing the original first set pressure value with the corrected first set pressure value, the method further comprises the following steps:

[0019] Acquire preset parameters, wherein the preset parameters also include a maximum pressure threshold;

[0020] The controller determines whether the corrected first set pressure value is greater than the maximum pressure threshold. If so, an alarm is issued and the driving mechanism is controlled to drive the push rod to move toward the side away from the cylinder at a preset pressure relief speed to relieve pressure and shrink the balloon; otherwise, the corrected first set pressure value replaces the original first set pressure value.

[0058] The pressure control mechanism 2 includes a cylinder 21, a push rod 22, and a balloon catheter 23;

[0059] The cylinder 21 is provided with a cavity 211. In this embodiment, a pressure measuring hole (not shown in the figure) is also provided on the side wall of the cylinder 21. The pressure measuring hole is connected with the cavity 211.

[0060] One end of the push rod 22 is a connecting end connected to the output end of the power source 1, and the other end is a free end extending into the cavity 211 and sliding along the cavity 211. A piston 221 is provided on the free end of the push rod 22, and the outer surface of the piston 221 is tightly matched with the inner surface of the cavity 211; in this embodiment, the piston 221 divides the cavity 211 into a first sub-cavity and a second sub-cavity, the push rod 22 is located in the first sub-cavity, and the pressure measuring hole is connected to the second sub-cavity.

[0061] The end of the cylinder 21 away from the push rod 22 is connected to the air inlet end of the balloon catheter 23, and the air outlet end of the balloon catheter 23 is connected to the balloon 3; in the present embodiment, the lumen of the balloon catheter 23 is connected between the second sub-cavity and the inner cavity of the balloon 3, and the push rod 22 moves in the cavity 211 under the action of the power source 1, and the piston 221 pressurizes or releases the pressure on the second sub-cavity, which is transmitted to the inner cavity of the balloon 3 through the lumen of the balloon catheter 23, thereby realizing the pressurized expansion or depressurized contraction of the balloon 3.

[0062] The pressure detection mechanism includes a first pressure detection component 41 and a second pressure detection component (not shown in the figure), wherein the first pressure detection component 41 is arranged on the cylinder 21, and is used to detect the cavity pressure value of the cavity 211; the second pressure detection component is arranged on the balloon 3, and is used to detect the surface pressure value of the balloon 3;

[0063] In this embodiment, the first pressure detection component is a pressure sensor fixed on the cylinder 21, and the sensing end of the pressure sensor (not shown in the figure) is located in the pressure measuring hole and is sealed with the inner wall of the pressure measuring hole to detect the pressure in the second sub-cavity;

[0064] The second pressure detection component is a micro pressure sensor (not shown in the figure) attached to the outer surface of the balloon 3; the pressure sensor and the micro pressure sensor are respectively connected to the controller by wired connection or wireless connection.

[0065] The controller of the present application provides the cavity pressure value and surface pressure value monitored in real time by the first pressure detection component 51 and the second pressure detection component to the controller. After analyzing them, the controller accurately controls the pressure increase or pressure release of the driving mechanism to enable the balloon to expand to a size that matches the stenosis.

[0066] In this embodiment, the power source 1 is a driving motor, and the push rod 22 is a screw with external threads evenly distributed on the outer wall. The cylinder 21 is located on the side close to the power source 1 and is provided with a threaded interface 212 matching the external threads of the push rod; the connecting end of the push rod 22 is provided with a quick connector 222. In this embodiment, the quick connector 222 is preferably an inwardly recessed quick connector groove.

When the driving motor is started, it drives the push rod to rotate to achieve extension or withdrawal relative to the threaded interface.

[0067] Since the pressure control mechanism 2 is a disposable consumable, the provision of a quick-connect groove at the connecting end of the push rod can reduce the installation time and thus improve work efficiency.

[0068] Embodiment 2 of the balloon pressure system of the present application:

[0069] See also Figure 2 As shown, the difference between the balloon pressure system of this embodiment and the first embodiment is that the power source 1 of this embodiment is a cylinder, and the connecting end of the push rod 22 is connected to the piston rod end of the cylinder through a quick connector 222.

[0070] Embodiment 2 of the balloon pressure system of the present application:

[0071] See also Figure 3 As shown, the difference between the balloon pressure system of this embodiment and the first embodiment is that the power source 1 of this embodiment is a hydraulic cylinder, and the connecting end of the push rod 22 is connected to the piston rod end of the hydraulic cylinder through a quick connector 222.

[0072] Embodiment of the balloon pressurization method of the balloon pressure system of the present application:

[0073] See also Figure 4 As shown, the present application also provides a balloon pressurization method, which specifically includes the following steps:

[0074] Step S101, obtaining preset parameters, which include a first set pressure value, a second set pressure value, a pressure injection speed, a pressure relief speed, and a pressure maintenance time. In this embodiment, the first set pressure value is the pressure value in the cylinder cavity when the balloon pressure system is in a factory state and the balloon is expanded to a target size, which is set to 230 mmHg in this embodiment; the second set pressure value is the pressure value applied to the balloon surface by the outside world when the balloon is expanded to the target size;

[0075] Step S102, the controller controls the driving mechanism to start based on the preset parameters, so that the power source pushes the push rod to move in the cavity at a preset pressing speed and in a direction extending into the cavity, so that the balloon is pressurized and expanded;

[0076] Step S103, the controller controls the first pressure detection component to detect the cavity pressure value in the cavity; in this embodiment, the first pressure detection component is a pressure sensor, and the sensing end of the pressure sensor detects the cavity pressure value of the second sub-cavity when the piston of the push rod squeezes the second sub-cavity of the cylinder;

[0077] Step S104, the controller determines whether the cavity pressure value reaches the first set pressure value; if so, the controller controls the second pressure detection component to detect the surface pressure of the balloon; otherwise, the controller jumps to step S102, controls the driving mechanism to continue to drive the push rod to move in the direction of the cavity, so that the balloon is pressurized and expanded;

[0078] Step S105, the controller determines whether the surface pressure value is equal to the second set pressure value; if so, the driving mechanism is controlled to stop so that the balloon maintains the current surface pressure value; otherwise, step S107 is executed to further compare and determine the surface pressure value;

[0079] In step S106, the controller maintains the current surface pressure value of the balloon. After a preset pressure maintenance time, the controller controls the drive mechanism to start and drive the push rod to move in the direction of exiting the cavity at a preset pressure release speed, so that the balloon releases pressure and shrinks. In this embodiment, the preset pressure maintenance time is set to 2 hours.

[0080] Among them, see Figure 5 As shown, when the controller determines that the surface pressure value is not equal to the second set pressure value, step S107 is executed to further compare and judge the surface pressure value, including the following steps:

[0081] Step S201, the controller determines whether the surface pressure value is greater than a second set pressure value;

[0082] Step S210, if yes, the controller issues an alarm and controls the driving mechanism to drive the push rod to move in the direction of exiting the cavity at a preset pressure relief speed, so that the balloon is depressurized and shrinks; in this embodiment, the balloon is depressurized and shrinks until the initial state, so as to avoid damage to the stenosis caused by the oversized balloon and facilitate the withdrawal of the balloon from the stenosis;

[0083] Step S220: otherwise, the first set pressure value is corrected, and the corrected first set pressure value replaces the original first set pressure value, and is compared with the cavity pressure value.

[0084] The surface pressure value detected by the second pressure detection component is compared with the second set pressure value. When the cavity pressure value in the pressurized cavity of the cylinder is equal to the first set pressure value, the controller can clearly detect the change in the balloon shape based on the comparison between the surface pressure value and the second set pressure value, so that the balloon pressure system can be adjusted in time to facilitate timely pressure relief to avoid damage to the stenosis caused by the balloon with an overly large shape after expansion, or to perform at least one pressurization so that the balloon can eventually expand to a size that matches the stenosis.

[0085] See also Figure 6 As shown, in some embodiments, in step S220, the first set pressure value is corrected, and the corrected first set pressure value replaces the original first set pressure value, specifically including:

[0086] Step S301, obtaining preset parameters, wherein the preset parameters also include a third set pressure value; in this embodiment, the third set pressure value is 10 mmHg;

[0087] Step S302: Substitute the preset first set pressure value and the third set pressure value into formula (1) to calculate the corrected first set pressure value. Formula (1) is: ;

[0088] in, is the first set pressure value after correction, is the preset first set pressure value, is the preset third set pressure value, n is the number of pressure corrections, in this embodiment, Take 10mmHg;

[0089] Step S303: replacing the original first set pressure value with the corrected first set pressure value.

[0090] The third set pressure value is used as a constant growth value to increase the cavity pressure in the pressurized cavity of the cylinder by small amounts and multiple times, thereby ensuring that the balloon can be smoothly expanded to the target size while avoiding a sudden increase in pressure, which may cause damage to the stenosis.

[0091] In some embodiments, before replacing the original first set pressure value with the revised first set pressure value in step S303, the balloon pressurization method of the present application further includes the following steps:

[0092] Step S401, obtaining preset parameters, wherein the preset parameters also include a maximum pressure threshold; in this embodiment, the maximum pressure threshold is set to 260 mmHg;

[0093] Step S402: The controller determines whether the corrected first set pressure value is greater than the maximum pressure threshold.

[0094] Step S410, if yes, an alarm is issued, and the driving mechanism is controlled to drive the push rod to move away from the cylinder at a preset pressure relief speed, so that the balloon is depressurized and contracted;

[0095] Step S420: otherwise, the corrected first set pressure value replaces the original first set pressure value.

[0096] By adopting the technical solution provided in this embodiment, the expansion condition of the balloon can be quickly grasped based on the comparison between the surface pressure value detected by the second pressure detection component and the second set pressure value, so that the balloon pressure pump can adjust the driving mechanism in time to achieve pressure relief protection or multiple pressurization to expand the balloon to the target size. The small amount of multiple pressurization method adopted in this application prevents the balloon from suddenly over-expanding, thereby avoiding damage to the stenosis.
