Preoperative preparation; S2. Place the insertion cannula outside the pressure measuring assembly and check whether the pressure measuring assembly and the pressure measuring controller are connected; S3. Use an insertion cannula to insert the pressure measuring part into the bladder through the urethra, pull out the insertion cannula, and the pressure measuring part will be deformed when the force of the insertion cannula disappears, and automatically restore its original shape and remain in the bladder. Then, the pressure measuring controller is worn on the patient, or attached to the patient's abdomen or thigh, and pressure measurement is started through the pressure sensor. When the pressure measuring part is a pressure measuring airbag, during its production and manufacturing process, gas of set pressure is injected into the pressure measuring airbag through a single-lumen tube.

[0021] Compared with the prior art, the present invention has the following advantages and beneficial effects: 1.

The cover can prevent the pressure sensor from directly contacting the inner wall of the bladder during the process of entering the bladder, which can protect the inner wall of the bladder from damage and avoid unstable data of the pressure sensor. After the detection is completed, the pressure measuring part in the bladder can be taken out by directly pulling the transmission line or single-lumen tube outside the body; 2. When the pressure measuring part in the present invention is a pressure measuring airbag, a gas of set pressure is injected into the pressure measuring airbag during manufacturing to fully expand it, and the rear end of the single-lumen tube is connected to the pressure sensor in the pressure measuring controller, which can be used for later pressure measurement; in addition, the setting of multiple chambers can detect in real time when the patient's bladder is abnormal. If a lesion occurs inside the patient, a certain chamber will be pressurized, and the gas in the chamber will overflow to the adjacent chamber, causing the pressure value of the pressure sensor in the area to increase, and the gas will enter the chamber of the adjacent area. In combination with the pressure measuring controller, a number of feedback pressure data can be obtained to know which specific part has a problem; 3. When the pressure measuring part of the present invention is designed with a through hole at the end of a single-lumen tube, the end of the single-lumen tube can be connected to the pressure measuring port of the pressure measuring sensor inside the pressure measuring controller to measure the bladder pressure.

[0024] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and drawings. The schematic implementation modes and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention. It should be noted that the present invention is already in the actual development and use stage.

[0025] Example 1 like Figures 1 to 3 As shown, this embodiment includes a built-in bladder pressure measuring device, including a pressure measuring controller 1 and a pressure measuring assembly, the pressure measuring assembly is connected to the pressure measuring controller 1, and is characterized in that: the pressure measuring assembly includes a single-lumen tube 2 and a pressure measuring part, one end of the single-lumen tube 2 is connected to the signal end of the pressure measuring controller 1, and the pressure measuring part is connected to the end of the single-lumen tube 2 away from the pressure measuring controller 1; Among them, the pressure measuring part is used to be inserted into the bladder through the insertion catheter 5 and left in the bladder, the pressure measuring part is used to detect the bladder pressure and feed back the pressure data or information to the pressure measuring controller 1, the pressure measuring controller 1 is used to monitor the bladder pressure data and the working status of the pressure measuring device in real time, obtain the real-time bladder pressure, bladder temperature, bladder pressure curve, maximum bladder pressure, bladder pressure change amplitude through calculation processing, generate a bladder pressure monitoring report and evaluation opinions, and store and display them.

[0026] like Figures 1 to 3 As shown, at least one pressure sensor 3 is arranged on the outer peripheral wall at the end of the pressure measuring part, a groove is opened at the pressure sensor 3, the pressure sensor 3 is arranged in the groove, and the pressure monitoring port of the pressure sensor 3 is lower than the upper surface of the groove, a wire channel is opened in the single-lumen tube 2 and the pressure measuring part, a transmission line is connected to the pressure sensor 3, and the transmission line passes through the wire channel and is electrically connected to the pressure measuring controller 1.

[0027] like Figure 1 , Figure 2 , Fig.11 , Fig.13 and Fig.14 As shown, the pressure measuring portion has flexibility and elastic deformation capability, is G-shaped, e-shaped, U-shaped or C-shaped, and has a circular, elliptical, quadrilateral or C-shaped cross section.

[0028] Specifically, Figures 1 to 3As shown, one or more pressure sensors 3 can be provided, and the transmission line is a soft and thin line, which is arranged in the single-lumen tube 2 and the pressure measuring part, and has both signal transmission and pull-out traction functions. The pressure sensor 3 and the pressure measuring part are fixedly packaged together, and the pressure measuring part and the single-lumen tube 2 are plastic-sealed as one, and the single-lumen tube 2 is connected to the signal interface of the pressure measuring controller 1. The pressure sensor 3 transmits the real-time collected bladder pressure and bladder temperature to the pressure measuring controller 1 through the transmission line, so as to realize real-time monitoring of the internal pressure and temperature of the bladder.

[0029] When measuring bladder pressure, the pressure measuring part is restricted in the lumen by inserting the cannula 5, and the pressure measuring part is sent into the bladder, and then the inserted cannula 5 is withdrawn, and the pressure measuring part gradually returns to its original shape after losing the restriction of the inserted cannula 5. It can be restored to a G shape, an E shape, a U shape or a C shape according to the actual shape of the pressure measuring part. Figure 1 and Figure 2 As shown, it can be restored to a G shape.

[0030] Preferably, Figure 2 As shown in (a), the single-lumen tube 2 and the pressure measuring part can be a separate structure. Figure 2 In (b), the single-lumen tube 2 and the pressure measuring part can also be an integrated structure; Figure 3 As shown, the groove in this embodiment can be opened on the outer circumferential wall or end face of the pressure measuring part, so the pressure sensor 3 has three settings (c), (d), and (e). Among them, a cavity is opened in the pressure measuring part of Figure (c), and Figures (d) and (e) are sealed settings.

[0031] Example 2 This embodiment is another implementation of Embodiment 1.

[0032] like Figures 4 to 10 As shown, a cover 23 is slidably connected in the groove, and the cover 23 and the inserted cannula 5 are sleeve-connected. The groove includes a limit groove 22 and a slide groove 21. The limit groove 22 and the slide groove 21 are connected and the connection is smoothly transitioned. The groove depth of the limit groove 22 is greater than the groove depth of the slide groove 21. The groove lengths of the limit groove 22 and the slide groove 21 are equal. The slide groove 21 is arranged near the end of the single-lumen tube 2, and an annular flange 51 is arranged at one end of the inserted cannula 5 near the cover 23. A clamping groove for clamping with the annular flange 51 is opened at one end of the cover 23 near the limit groove 22. The radius of the outer peripheral wall of the cover 23 is the same as the outer diameter of the single-lumen tube 2.

[0033] like Figures 6 to 9 As shown, a rotating shaft is arranged between the limit groove 22 and the slide groove 21, and a seesaw 24 is rotatably connected to the rotating shaft. The two ends of the seesaw 24 are respectively located in the limit groove 22 and the slide groove 21. At least one pressure sensor 3 is also arranged on the end surface of the seesaw 24 close to the slide groove 21. The seesaw 24 located on one side of the slide groove 21 is an inclined surface.

[0034] Specifically, when performing bladder pressure measurement on a patient, the pressure measuring device can be worn on the patient. Preferably, the pressure measuring controller 1 is provided with a strap that can be worn on the patient, so that the patient's daily life will not be affected during the pressure measurement process, and the patient does not need to stay in the hospital for observation; the pressure measuring part is sent into the bladder by inserting the cannula 5. The inserted cannula 5 is cylindrical, and the inner diameter is larger than the outer diameter of the single-lumen tube 2 but smaller than the radius when the cover 23 is located in the slide groove 21. After the inserted cannula 5 is connected with the cover 23, the cover 23 is slid to the slide groove 21, and then the pressure measuring part is introduced into the bladder through the urethra by the inserted cannula 5. In the process of the inserted cannula 5 pushing the cover 23 into the bladder, the thrust of the inserted cannula 5 will limit the cover 23 in the slide groove 21. When the pressure measuring part is in the bladder, the inserted cannula 5 can be pulled out separately, so that the inserted cannula 5 leaves the pressure measuring part and leaves the patient's body along the urethra.

[0035] Preferably, an annular flange 51 is provided at the end of the insertion cannula 5, and a slot is provided on the side of the cover 23 facing the limiting groove 22. During preoperative preparation, the annular flange 51 can be inserted into the slot. It should be noted that the material of the annular flange 51 and the cover 23 can preferably be a flexible material with a relatively hard texture. When the insertion cannula 5 is pulled out, as described above, the annular flange 51 drives the cover 23 to move toward the limiting groove 22. The groove depth of the limiting groove 22 is greater than the groove depth of the slide groove 21. Therefore, the cover 23 moves to the limiting groove. 22, the radius of the single-lumen tube 2 changes and it tilts toward the limiting groove 22 and moves into the limiting groove 22. The annular flange 51 also leaves the slot because the radius of the cover 23 changes after entering the limiting groove 22. The insertion cannula 5 continues to be pulled so that the cover 23 is completely located in the limiting groove 22. As the insertion cannula 5 leaves the single-lumen tube 2, the squeezing force on the single-lumen tube 2 disappears and gradually returns to its original state. The shape of the pressure measuring part can be G-shaped, e-shaped, U-shaped or C-shaped, which can be deformed and located in the bladder and is not easy to slide out.

[0036] When the cover 23 slides to the limiting groove 22, the seesaw 24 at the bottom of the limiting groove 22 is pressurized, and under the action of the rotating shaft, the seesaw 24 at the bottom of the slide groove 21 rises, and the pressure sensor 3 thereat is exposed to the outside of the slide groove 21. The pressure sensor 3 at the slide groove 21 is an inclined surface, which can make the seesaw 24 at the slide groove 21 remain parallel to the single-lumen tube 2 when moving up. The cover 23 is used to protect the pressure sensor 3 during the process of entering the bladder, so as to prevent the pressure sensor 3 from contacting the inner wall of human tissue when it is not stabilized in the bladder, thereby affecting the transmission data of the pressure sensor 3; at the same time, the cover 23 is smooth, which can protect the human tissue from being scratched by multiple pressure sensors 3, thereby preventing the patient from suffering secondary injury.

[0037] After the detection is completed, the transmission line or the single-lumen tube 2 on the single-lumen tube 2 can be directly pulled, and the single-lumen tube 2 can be moved out of the outside world along the bladder and urethra. During the movement, the cover 23 loses the limiting effect of the insertion tool, and when the single-lumen tube 2 is pulled out, one side of the limit groove 22 is exposed first. Therefore, during the removal process, the cover 23 will move toward the slide groove 21 when it contacts the human tissue. Even if the moving distance is a little, the seesaw 24 will change, causing the seesaw 24 at one end of the pressure sensor 3 to move downward, thereby avoiding the pressure sensor 3 from contacting the urethra when passing through the urethra, affecting the measurement data or causing harm to the human body. Preferably, the cover 23 is surrounded by smooth curved surfaces.

[0038] Example 3 like Fig.11 and Fig.13 As shown, the pressure measuring part is provided with a pressure measuring airbag 4 , and an air hole is penetrated through the end or the outer circular side wall of the pressure measuring part, and the air hole is connected with the lumen of the single-lumen tube 2 and the inner cavity of the pressure measuring airbag 4 .

[0039] Specifically, Fig.11 As shown, a pressure measuring airbag 4 is provided at the end of the pressure measuring part. During the manufacturing process, gas of set pressure is injected into the pressure measuring airbag 4 through the single-lumen tube 2. After the pressure measuring airbag 4 is inflated and expanded, the rear end of the single-lumen tube 2 is fixedly sealed and connected to the pressure measuring port of the pressure sensor 3 in the pressure measuring controller 1 as a whole, thereby connecting the pressure measuring airbag 4 with the pressure sensor 3 in the pressure measuring controller 1 to implement pressure measurement.

[0040] Preferably, Fig.11 As shown in Figure (f), the pressure measuring airbag 4 can be set on the outer circumferential wall of the pressure measuring part and the gas can be injected through the air hole. Alternatively, as shown in Figure (g), the pressure measuring airbag 4 can be set at the end of the pressure measuring part and the air hole can be opened at the end of the pressure measuring part for injecting gas.

[0041] Example 4 This embodiment is another implementation of Embodiment 3.

[0042] like Fig.12 As shown, a plurality of annular grooves are formed on the outer peripheral wall of the pressure measuring airbag 4, and the grooves are used to divide the pressure measuring airbag 4 into a plurality of chambers, each of which is interconnected, and a pressure sensor 3 is also arranged in the chamber, and the pressure sensor 3 is used to be electrically connected to the pressure measuring controller 1 through the transmission line in the single-lumen tube 2, and the groove is annular, and the axis of the groove and the single-lumen tube 2 coincide or are inclined.

[0043] Specifically, this embodiment is substantially the same as the embodiment 1, the only difference being that the pressure measuring part in this embodiment is a pressure measuring airbag 4 .

[0044] In this embodiment, a plurality of grooves are provided on the outer peripheral wall of the pressure measuring airbag 4. The texture of the pressure measuring airbag 4 at the grooves is thicker than that at other positions of the airbag. Before the pressure measuring airbag 4 enters the bladder, it is completely wrapped in the lumen of the insertion cannula 5. The insertion cannula 5 guides the pressure measuring airbag 4 into the bladder for pressure measurement. The grooves can divide the airbag into a plurality of chamber areas, and each chamber area is interconnected. In this embodiment, an air hole is provided on the single-lumen tube 2 located at the pressure measuring airbag 4 for inflating the pressure measuring airbag 4.

[0045] Method of use: The single-lumen tube 2 is still inserted into the bladder through the insertion cannula 5, and the pressure measuring balloon 4 is confined in the lumen of the insertion cannula 5. After the pressure measuring part is inserted into the bladder as in Example 1, the insertion cannula 5 can be taken out, and the pressure measuring part remains in the bladder. The pressure sensor 3 in the pressure measuring controller 1 is connected to the pressure measuring balloon 4, and the bladder pressure can be directly obtained.

[0046] Preferably, an additional pressure sensor 3 can be set in the area inside each chamber of the pressure measuring airbag 4, and a diaphragm and a leakage hole are provided between adjacent chambers. Due to the setting of multiple chambers of the pressure measuring airbag 4, real-time detection can be performed when abnormalities occur in the patient's bladder. Under normal circumstances, the pressure values ​​in multiple connected chambers are equal. If a lesion occurs inside the patient, such as a foreign body or a tumor in the bladder, a certain chamber will be pressurized, and the gas in the chamber will overflow to the leakage hole on the diaphragm of the adjacent chamber, causing the pressure value of the pressure sensor 3 in the chamber to increase. In combination with the pressure measuring controller 1, several feedback pressure data can be obtained to know which specific part has a problem, so that the patient can be treated in time. When the bladder pressure is uneven, it can reflect more subtle changes relative to a single airbag.

[0047] Example 5 like Fig.14 As shown, a through hole is formed at one end of the single-lumen tube 2 away from the pressure measuring controller 1 , and the through hole is communicated with the lumen of the single-lumen tube 2 .

[0048] Specifically, this embodiment is basically the same as Embodiment 3. This embodiment eliminates the design of the pressure measuring airbag 4, and a through hole is provided on the pressure measuring portion to communicate with the bladder. The end of the pressure measuring portion is connected to the pressure measuring port of the pressure measuring sensor inside the pressure measuring controller 1 to measure the bladder pressure. Similarly, the single-lumen tube 2 can be introduced into the bladder for pressure measurement by inserting the cannula 5.

[0049] Example 6 This embodiment provides a method for using a built-in bladder pressure measuring device. The built-in bladder pressure measuring device described in embodiments 1 to 5 is used to measure pressure, including the following steps: S1. Preoperative preparation; S2, insert the cannula 5 outside the pressure measuring assembly, and check whether the pressure measuring assembly and the pressure measuring controller 1 are connected; S3, use the insertion cannula 5 to send the pressure measuring part into the bladder through the urethra, pull out the insertion cannula 5, the pressure measuring part is deformed when the force of the insertion cannula 5 disappears, and automatically restores its original shape and remains in the bladder, then the pressure measuring controller 1 is worn on the patient, or pasted on the patient's abdomen or thigh, and the pressure measurement is started through the pressure sensor 3. When the pressure measuring part is a pressure measuring airbag 4, during its production and manufacturing process, a gas of a set pressure is injected into the pressure measuring airbag 4 through the single-lumen tube 2. After the pressure measuring airbag 4 is inflated and expanded, the rear end of the single-lumen tube 2 is fixedly sealed and connected to the pressure measuring port of the pressure sensor 3 in the pressure measuring controller 1 as a whole, and fixed on the pressure measuring controller 1. According to the pressure value of the pressure measuring airbag after the gas is injected, the pressure measuring device is calibrated, and the bladder pressure can be directly obtained during measurement; S4, the pressure measuring controller 1 records and processes the data measured by the pressure sensor 3, and issues an alarm when the bladder pressure value exceeds the set safe bladder pressure warning value or the pressure measuring device is abnormal; S5. When starting and ending the test, the pressure measurement controller 1 also has an operation prompt function and an alarm function. After the pressure measurement is completed, the pressure measurement part in the bladder is pulled out by pulling the transmission line or single-lumen tube 2 outside the body.

[0050] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention.
