Description

Technical Field

[0001] The present invention relates to the field of medical devices, and more particularly, to a medical balloon pressure measuring device. Background Art

[0002] Trigeminal neuralgia is a sudden and intense electric shock-like pain that occurs in a certain area of the face. Its incidence rate not only increases year by year but also shows a trend of getting younger. Percutaneous balloon compression (PBC) is a procedure that punctures the foramen ovale through the skin and introduces a balloon into the Meckel's cave to compress the semilunar ganglion, thereby achieving the purpose of treating trigeminal neuralgia. With its advantages such as safe operation, low risk, and reliable treatment effect, it has become one of the main surgical treatment methods for primary trigeminal neuralgia.

[0003] The treatment effect of the surgery and the occurrence of postoperative complications are closely related to the balloon compression time and pressure value. However, usually, the pressure during balloon expansion during the operation has always been determined by intraoperative imaging and the surgeon's "hand feeling" and cannot be quantified. The general experience is to inject 0.5 - 0.8 ml of non-ionic contrast agent. But for beginners, it is very difficult to quickly master the so-called "hand feeling", resulting in poor postoperative effects for patients and an increase in complications. At the same time, to achieve the best treatment effect, the size of the balloon pressure changes with the change of the balloon position. The current balloon device completely relies on the doctor's control, which affects postoperative recovery. Summary of the Invention

[0038] In addition, if terms such as "first", "second", etc. are used only for distinguishing descriptions, they cannot be understood as indicating or implying relative importance.

[0039] It should be noted that, without conflict, the features in the embodiments of the present invention can be combined with each other.

[0040] The following Figures 1 to 3 will be used to describe in detail the medical balloon pressure measuring device 10 provided in this embodiment.

[0041] Referring to Figure 1 and Figure 2 , an embodiment of the present invention provides a pressure regulating and pressure measuring structure, including a pressure regulating valve body 100, a pressure regulating member 200 and a detector; the pressure regulating valve body 100 is provided with a pressure regulating cavity 110 and a first pipe orifice 120, a second pipe orifice 130, a third pipe orifice 140 and a fourth pipe orifice 150 that communicate with the pressure regulating cavity 110; the first pipe orifice 120 is used for introducing a fluid, and the second pipe orifice 130 is used for discharging the fluid; the pressure regulating member 200 is movably arranged at the third pipe orifice 140, the pressure regulating member 200 is used to block the third pipe orifice 140, and is used to approach or move away from the center of the pressure regulating cavity 110 during the movement relative to the first pipe orifice 120; the detector is arranged at the fourth pipe orifice 150, and the detector is used to detect in real time a pressure value representing the fluid pressure in the pressure regulating cavity 110 during the movement of the pressure regulating member 200 relative to the third pipe orifice 140; the pressure regulating member 200 is used to control the pressure according to the pressure value.

[0042] The first pipe orifice 120, the second pipe orifice 130, the third pipe orifice 140 and the fourth pipe orifice 150 of the pressure regulating valve body 100 are all communicated with the pressure regulating cavity 110, and the structure of the pressure regulating valve body 100 is similar to a four-way structure. In this embodiment, the pressure regulating valve body 100 adopts a four-way.

[0043] The first pipe orifice 120 and the second pipe orifice 130 are used for the fluid to pass through. The fluid can be a liquid or a gas. The flowing-out fluid flows to the balloon in this embodiment. The actual flow direction of the fluid is different according to the use scenario of the pressure regulating and pressure measuring structure. For example, the first pipe orifice 120 introduces the fluid and the second pipe orifice 130 discharges the fluid; or the second pipe orifice 130 introduces the fluid and the first pipe orifice 120 discharges the fluid. In this embodiment, the pressure regulating and pressure measuring structure is mainly used in the surgical operation of trigeminal neuralgia. Therefore, the pressure regulating and pressure measuring structure is used in cooperation with the balloon.

[0044] The pressure regulating member 200 reciprocates along the third pipe orifice 140 to approach or move away from the center of the pressure regulating cavity 110, which can change the magnitude of the fluid pressure in the pressure regulating cavity 110, thereby adjusting the pressure of the balloon communicated with the pressure regulating cavity 110. Among them, the movement of the pressure regulating member 200 relative to the third pipe orifice 140 can be realized manually or electrically adjusted.

[0045] The detector can detect the pressure in the pressure regulating chamber 110 at any time, that is, it can detect the pressure in the balloon in real time. Before the operation, the balloon pressure is adjusted and controlled through the pressure regulating member 200 until the balloon pressure meets the pressure required for the operation conditions, and then the adjustment of the pressure regulating member 200 is stopped, so that the balloon compression time and the pressure value can be accurately adjusted and controlled. Thus, the treatment effect of the surgical operation for trigeminal neuralgia is improved.

[0046] Referring to Figure 1 and Figure 2 , in this embodiment, the pressure regulating and measuring structure further includes a controller and a display 311; both the display 311 and the detector are in communication with the controller; the controller is used to obtain the pressure value and control the display 311 to display the pressure value.

[0047] After the detector detects the pressure value, the pressure value is displayed on the display 311 in real time, and the doctor decides whether to adjust the pressure regulating member 200 according to the pressure value displayed on the display 311. Specifically, the display 311 is a display screen. By displaying the pressure value on the display 311, it is convenient for the doctor to intuitively obtain the pressure value information.

[0048] Specifically, the detector is a pressure sensor. When the pressure regulating member 200 moves closer to the center of the pressure regulating chamber 110, the fluid in the pressure regulating chamber 110 is compressed, and the pressure sensor sends the received pressure change signal to the controller. After receiving the pressure change signal, the controller performs conversion and then controls the display 311 to display. In this way, it is possible to adjust and control the pressure in the balloon to a preset pressure value according to the treatment needs.

[0049] Referring to Figure 1 and Figure 2 , in this embodiment, the pressure regulating and measuring structure further includes a timer; the timer is in communication with the controller; the timer is used to perform cumulative timing when the pressure value reaches the preset pressure value.

[0050] Before the operation, the doctor needs to adjust and control the pressure of the balloon in advance until the pressure value displayed on the display 311 reaches the preset pressure value, and then start the timer to time, so as to control the balloon compression time. The timer timing can be positive timing or countdown timing.

[0051] In this embodiment, the pressure regulating and measuring structure further includes a reminder; the reminder is in communication with the controller; the reminder is used to emit a reminder sound when the cumulative timing of the timer reaches the preset time period.

[0052] When the timer finishes timing, the reminder will emit a reminder sound. Specifically, the reminder can be an alarm. Thus, it can provide convenience for the doctor to control the balloon compression time and ensure the treatment effect of the operation.

[0053] Referring to Figure 1 andFigure 2 In this embodiment, the pressure regulating member 200 includes a pressure regulating portion and a sealing ring; the sealing ring is disposed on the pressure regulating portion, and the outer wall of the sealing ring is sealingly engaged with the inner wall of the third pipe orifice 140. Specifically, the third pipe orifice 140 has a circular channel structure, and the sealing ring is cylindrical. The sealing engagement between the sealing ring and the third pipe orifice 140 can improve the sensitivity of pressure regulation during the movement of the pressure regulating member 200 and make it easier to control the pressure regulation.

[0054] Refer to Figure 1 and Figure 2 In this embodiment, the pressure regulating portion includes a rod portion 260 and a head portion 270 connected to one end of the rod portion 260; the sealing ring is sleeved on the outer portions of both the rod portion 260 and the head portion 270. By adopting the combination of the rod portion 260 and the head portion 270, the contact area with the sealing ring is increased, and the sealing ring is fixed more firmly.

[0055] Refer to Figure 1 and Figure 2 In this embodiment, the pressure regulating member 200 further includes an introduction portion 250; the introduction portion 250, the rod portion 260, and the head portion 270 are connected in sequence; the outer wall of the introduction portion 250 has a clearance fit with the inner wall of the third pipe orifice 140, and the introduction portion 250 is used to extend into or out of the third pipe orifice 140.

[0056] Specifically, the introduction portion 250, the rod portion 260, and the head portion 270 are arranged in sequence from top to bottom. The introduction portion 250, the rod portion 260, and the head portion 270 are all cylindrical. The diameter of the rod portion 260 is smaller than the diameter of the head portion 270, and the diameter of the head portion 270 is smaller than the diameter of the introduction portion 250. The diameter of the introduction portion 250 is smaller than the diameter of the third pipe orifice 140, which is convenient for extending into or out of the third pipe orifice 140. The rod portion 260 and the head portion 270 are both embedded in the sealing ring, and are sealingly engaged with the third pipe orifice 140 through the sealing ring.

[0057] Refer to Figure 1 and Figure 2 In this embodiment, the pressure regulating member 200 further includes a limiting portion 230; the limiting portion 230, the introduction portion 250, the rod portion 260, and the head portion 270 are connected in sequence; the limiting portion 230 is used to abut against the pressure regulating valve body 100 when the pressure regulating member 200 moves relative to the third pipe orifice 140 to a preset position, so as to stop the pressure regulating member 200.

[0058] Specifically, the "preset position" refers to the position where the pressure regulating member 200 abuts against the regulating housing, and the preset position is set according to the limit position of the downward movement of the pressure regulating member 200.

[0059] Specifically, the limiting portion 230 is also columnar, the diameter of the limiting portion 230 is larger than the diameter of the guiding portion 250, and the diameter of the limiting portion 230 is larger than the diameter of the third pipe orifice 140. When the pressure regulating member 200 moves downward to a preset position, the limiting portion 230 abuts against the pressure regulating valve body 100, and the pressure regulating member 200 cannot move downward any further.

[0060] Refer to Figure 1 and Figure 2 , in this embodiment, the pressure regulating valve body 100 is provided with an abutting surface 101, and the third pipe orifice 140 is opened on the abutting surface 101; the limiting portion 230 has a limiting surface 240, and the limiting surface 240 is used for contacting the abutting surface 101 when the limiting portion 230 abuts against the pressure regulating valve body 100.

[0061] Specifically, the abutting surface 101 is horizontally arranged, the limiting surface 240 is horizontally arranged, and when the pressure regulating member 200 moves downward to the preset position, the limiting surface 240 contacts the abutting surface 101.

[0062] Refer to Figure 1 and Figure 2 , in this embodiment, the third pipe orifice 140 is arranged at the top of the pressure regulating valve body 100, and the fourth pipe orifice 150 is arranged at the bottom of the pressure regulating valve body 100. Specifically, the center line of the third pipe orifice 140 coincides with the center line of the fourth pipe orifice 150.

[0063] The third pipe orifice 140 is located above the fourth pipe orifice 150. During the process of the pressure regulating member 200 moving downward in the third pipe orifice 140, the detector can more quickly and sensitively detect the pressure value.

[0064] Specifically, the pressure regulating chamber 110 is cylindrical, the third pipe orifice 140 is arranged at the top of the pressure regulating chamber 110, the fourth pipe orifice 150 is arranged at the bottom of the pressure regulating chamber 110, and the first pipe orifice 120 and the second pipe orifice 130 are arranged at the side of the pressure regulating chamber 110.

[0065] Refer to Figure 1 and Figure 2 , in this embodiment, the detector is arranged at the bottom of the pressure regulating valve body 100, and the detector is hermetically connected to the fourth pipe orifice 150. Specifically, the pressure regulating valve body 100 is arranged on the detector, which helps the detector more sensitively sense the pressure and detect the pressure value.

[0066] Refer to Figure 1 and Figure 2 , in this embodiment, the bottom of the pressure regulating valve body 100 is provided with a sealing surface 102, and the fourth pipe orifice 150 is opened on the sealing surface 102; the sealing surface 102 is used for hermetically contacting the detector. Specifically, the sealing surface 102 is arranged in parallel with the abutting surface 101.

[0067] In this embodiment, the centerlines of the first pipe orifice 120 and the second pipe orifice 130 coincide. In other embodiments, the centerlines of the first pipe orifice 120 and the second pipe orifice 130 may be arranged at an angle.

[0068] In this embodiment, the centerline of the first pipe orifice 120 is perpendicular to the centerline of the third pipe orifice 140. It should be noted that the "perpendicular" in this article does not require the angle between the two to be exactly 90°, but can be slightly inclined. For example, within the range of 88° - 90° of the angle, the two can still be considered perpendicular. Example: The angle between the centerline of the first pipe orifice 120 and the centerline of the third pipe orifice 140 can also be 88°, 89°, etc.

[0070] Refer to Figure 1 and Figure 2 , in this embodiment, the pressure regulating and measuring structure further includes a first connecting pipe and a second connecting pipe; both ends of the first connecting pipe are respectively connected to the first pipe orifice 120 and the catheter orifice 340, and both ends of the second connecting pipe are respectively connected to the second pipe orifice 130 and the medicine inlet 350.

[0071] Specifically, one end of the first connecting pipe is connected to the first pipe orifice 120, and the other end of the first connecting pipe is connected to the catheter orifice 340. One end of the second connecting pipe is connected to the second pipe orifice 130, and the other end of the second connecting pipe is connected to the medicine inlet 350.

[0072] Refer to Figure 1 and Figure 2 , in this embodiment, the pressure regulating member 200 is rotatably connected to the pressure measuring device housing 300, and the pressure regulating member 200 is used to move relative to the third pipe orifice 140 during the process of rotating relative to the pressure measuring device housing 300. Rotate the pressure regulating member 200 back and forth in a positive and negative direction, so that the pressure regulating member 200 moves closer to or farther away from the center of the pressure regulating cavity 110 along the third pipe orifice 140.

[0073] Refer to Figure 1 and Figure 2, in this embodiment, the pressure regulating member 200 includes a threaded portion 220. The pressure measuring device housing 300 is provided with a threaded hole, and the threaded portion 220 is threadedly connected to the threaded hole. The pressure regulating member 200 is threadedly connected to the pressure regulating valve body 100 to better control the rotation process of the pressure regulating member 200. Specifically, the threaded portion 220, the limiting portion 230, the guiding portion 250, the rod portion 260, and the head portion 270 are connected in sequence, and the threaded portion 220, the limiting portion 230, the guiding portion 250, the rod portion 260, and the head portion 270 are coaxially arranged. By adopting the design of the threaded structure for the pressure regulating member 200, real-time and precise pressure regulation and control can be ensured, which is convenient for doctors to operate.

[0074] Refer to Figure 1 and Figure 2 , in this embodiment, the pressure measuring device housing 300 is provided with an installation hole 312 communicating with the accommodation cavity 330; the pressure regulating and measuring structure further includes a nut, the nut is installed in the installation hole 312, and the threaded portion 220 is threadedly connected to the nut.
