Description

Technical Field

[0001] The present disclosure relates to the field of medical technologies, and particularly to a prostate pressure measurement system. Background Art

[0002] Benign prostatic hyperplasia is the most common urodynamic disorder in middle-aged and elderly men.

[0003] The treatment methods for benign prostatic hyperplasia (BPH) are surgical treatment and drug treatment. The surgical methods include: transurethral resection of the prostate, plasma prostatectomy, and laser prostatectomy; the drug treatment methods are mainly finasteride and tamsulosin hydrochloride. Clinically, there is a lack of specific values of the prostate pressure on the urethra. The direct effect of prostatic hyperplasia on the urethra is compression. When prostatic hyperplasia is excessive and the urethral pressure is too high, it will cause complete occlusion of the patient's urethra, resulting in difficulty in urination and urinary retention.

[0004] The current traditional measurement methods cannot directly reflect the pressure of the prostate on the urethra, resulting in subjectivity in clinical diagnosis, inability to accurately evaluate the degree of prostatic hyperplasia and its clinical significance. Moreover, the degree of urethral compression varies among different patients with prostatic hyperplasia. The indirect diagnosis method cannot objectively treat the patient's condition according to the patient's specificity. And when injecting the contrast agent, the injection tube will shake and is prone to falling off, requiring medical staff to repeatedly check after assembly, which is rather troublesome.

[0037] Currently, the traditional method of prostate pressure measurement cannot directly reflect the pressure of the prostate on the urethra, resulting in the subjectivity of clinical diagnosis, inability to accurately evaluate the degree of prostate hyperplasia and its clinical significance, and the degree of urethral compression varies from patient to patient with prostate hyperplasia. The indirect diagnosis method cannot objectively treat the patient's condition according to the patient's specificity. Moreover, when injecting the contrast agent, the injection tube will shake and is prone to fall off, requiring medical staff to repeatedly check after assembly, which is rather troublesome.

[0038] Based on the above problems, embodiments of the present disclosure provide a prostate pressure measurement system. The pressure of the medium injected into the balloon is detected by a medium pressure gauge, and the pressure of the prostate on the urethra is determined by the pressure in the balloon. Secondly, the clamping cooperation between the clamping portion on the medium filling tube and the limiting portion on the connecting tube realizes the relative fixation of the first end of the connecting tube and the medium inlet of the medium filling tube, thereby avoiding the loosening or detachment of the connection between the connecting tube and the medium filling tube during the medium injection, and further improving the measurement effect and efficiency.

[0039] Figure 1 Shown therein is a schematic diagram of the overall structure of the prostate pressure measurement system in an embodiment of the present disclosure. Figure 2 Shown therein is a partial cross-sectional schematic diagram of the prostate pressure measurement system in an embodiment of the present disclosure. Figure 3 Shown therein is an embodiment of the present disclosure Figure 2 An enlarged view of A therein. In Figure 1 , Figure 2 and Figure 3 In the example, the prostate pressure measurement system includes a catheter 10, at least one balloon 20, a medium filling tube 30, a medium pressure gauge 40, and a connecting tube 50.

[0040] The catheter 10 includes a guide wire channel 101 for a guide wire to penetrate and at least one medium channel 102. The balloon 20 is disposed around the catheter 10 and near one end of the catheter 10, and the medium channel 102 is communicated with the balloon 20. One end of the medium filling tube 30 is connected to the catheter 10 to form a medium outlet 301 communicated with the medium channel 102, and the other end forms a medium inlet 302. The medium pressure gauge 40 has an outlet 401 communicated with the medium inlet 302 of the medium filling tube 30, and an inlet 402 for injecting the medium; wherein, when the medium flows through the medium pressure gauge 40, the pressure gauge can obtain the pressure of the medium injection. The connecting tube 50 has a first end 51 hermetically and communicatively sleeved with the medium inlet 302 of the medium filling tube 30, and a second end 52 communicated with the outlet 401 of the medium pressure gauge 40; at least one limiting portion 511 is provided on the side wall of the first end 51 of the connecting tube 50, and at least one clamping portion 31 for clamping and cooperating with the limiting portion 511 is provided on the corresponding side wall of the medium inlet 302 of the medium filling tube 30.

[0041] Through the above arrangement, the medium pressure meter 40 detects the pressure of the medium injected into the balloon 20, and determines the pressure of the prostate on the urethra through the pressure in the balloon 20. Secondly, the engagement between the clamping portion 31 on the medium filling tube 30 and the upper limit portion 511 on the connecting tube 50 realizes the relative fixation between the first end 51 of the connecting tube 50 and the medium inlet 302 of the medium filling tube 30, thereby preventing the connection between the connecting tube 50 and the medium filling tube 30 from loosening or falling off when the medium is injected, thereby improving the measurement effect and efficiency.

[0042] Exemplarily, the limiting portion 511 is implemented as a limiting hole, and the holding portion 31 is implemented as a holding column engaged with the limiting hole.

[0043] Exemplarily, the catheter 10 is made of silicone rubber, polytetrafluoroethylene or polyurethane rubber. Exemplarily, the surface of the catheter 10 is provided with scale lines 11 spaced apart along the length direction. The setting of the scale lines 11 can facilitate the user to adjust the length of the catheter 10 in the patient's body.

[0044] Exemplarily, the liquid inlet 402 of the medium pressure meter 40 is connected to a container storing the medium. The medium pressure meter 40 can extract the medium and inject it into the medium filling pipe 30, and can also detect the pressure of the medium filling. Exemplarily, the medium is gas or contrast agent.

[0045] Figure 4 FIG. 1 is a schematic cross-sectional view of the catheter 10 in an embodiment of the present disclosure. Figure 2 and Figure 4 In the example, the balloon 20 is implemented as one, and the medium channel 102 is implemented as one; the balloon 20 is arranged around the catheter 10 and close to one end of the catheter 10, and the medium channel 102 is connected to the balloon 20. Exemplarily, the cross section of the medium channel 102 is annular, and the guidewire channel 101 is arranged inside the medium channel 102. In another embodiment, the balloon 20 and the medium channel 102 can be implemented as two; the two balloons 20 are spaced apart along the length of the catheter 10; the two medium channels 102 are formed by dividing a ring-shaped channel into two semicircular channels.

[0046] Figure 5 The embodiment of the present disclosure is shown in Figure 2 The enlarged view of B in Figure 5 In the example, a plurality of communicating holes 103 are formed in the catheter 10 and are evenly distributed along the circumference and are used to connect the balloon 20 with the medium channel 102. The advantage of such a configuration is that the medium in the medium channel 102 can flow evenly to various places inside the balloon 20, so that various places of the balloon 20 can be expanded simultaneously and evenly.

[0047] In Figure 2 and Figure 3 the example, both the connecting pipe 50 and the medium filling pipe 30 are implemented as circular pipes. In this embodiment, the first end 51 of the connecting pipe 50 is inserted into the medium inlet 302 of the medium filling pipe 30. Exemplarily, at least a pair of guiding columns 512 are provided on the wall surface of the first end 51 of the connecting pipe 50 facing the medium filling pipe 30, and at least a pair of guiding cavities 303 corresponding to the positions of the guiding columns 512 are provided on the wall surface of the medium filling pipe 30 facing the first end 51 of the connecting pipe 50; the line connecting between each pair of the guiding cavities 303 passes through the center of the medium filling pipe 30. In this embodiment, both the guiding columns 512 and the guiding cavities 303 are implemented as a pair. The advantage of such a setting is that when the pair of guiding columns 512 are inserted into the pair of guiding cavities 303, the clamping portion 31 on the medium filling pipe 30 is aligned with the limiting portion 511 on the connecting pipe 50, and there is no need to relatively rotate the medium filling pipe 30 and the connecting pipe 50 to align the clamping portion 31 on the medium filling pipe 30 with the limiting portion 511 on the connecting pipe 50, so as to improve the installation efficiency. In another embodiment, multiple pairs of the guiding columns 512 and the guiding cavities 303 can also be respectively provided. In another embodiment, the forming positions of the guiding columns 512 and the guiding cavities 303 can be interchanged.

[0048] Exemplarily, the clamping portion 31 remains in a state of snap-fitting with the limiting portion 511. For example, in Figure 3 the example, a receiving cavity 304 for receiving the first end 51 of the connecting pipe 50 is formed at the medium inlet 302 of the medium filling pipe 30. As can be seen from the appendix Figure 3 the guiding cavity 303 is formed by extending from the bottom wall surface of the receiving cavity 304. The clamping portion 31 is slidably combined with the corresponding side wall of the medium inlet 302 of the medium filling pipe 30; a retaining ring 311 is provided on the part of the clamping portion 31 extending into the receiving cavity 304, and an elastic member 312 is sleeved on the clamping portion 31 between the retaining ring 311 and the side wall of the medium filling pipe 30. Exemplarily, the elastic member 312 is implemented as a spring, and the elastic force of the spring makes the clamping portion 31 remain in a state of snap-fitting with the limiting portion 511. In another embodiment, the elastic member 312 is implemented as a rubber block.

[0049] Exemplarily, an operating end 313 is formed at one end of the clamping portion 31 outside the medium filling pipe 30 to facilitate the user to pull the clamping portion 31. Further exemplarily, the operating end 313 is implemented in a shape that is convenient for pulling the clamping portion 31.

[0050] In another embodiment, the medium inlet 302 of the medium filling pipe 30 is inserted into the first end 51 of the connecting pipe 50. In this way, the limiting portion 511 is formed on the inner side wall of the first end 51 of the connecting pipe 50, and the engaging portion that is engaged with the limiting portion 511 is configured in a shape that guides the medium inlet 302 of the medium filling pipe 30 to be inserted into the first end 51 of the connecting pipe 50.

[0051] Those skilled in the art can understand that when assembling the connecting pipe 50 and the medium filling pipe 30, the user pulls the operating end 313 outwards until the engaging portion 31 is no longer engaged with the limiting portion 511. During this process, the spring 312 is in a compressed state. After the first end 51 of the connecting pipe 50 is placed in the accommodating cavity 304 and the guiding column 512 is inserted into the corresponding guiding cavity 303, at this time the engaging portion 31 is aligned with the limiting portion 511, and then the operating end 313 is released. The engaging portion 31 is re-engaged with the limiting portion 511 due to the elastic force of the spring 312 and remains in a state of being engaged with the limiting portion 511 under the elastic force of the spring 312 to complete the relative fixation of the connecting pipe 50 and the medium filling pipe 30, thereby avoiding loosening or detachment at the connection between the connecting pipe 50 and the medium filling pipe 30 during medium injection, and further improving the measurement effect and efficiency.

[0052] In another embodiment, the spring 312 is sleeved on the engaging portion 31 and is located between the operating end 313 and the outer wall of the medium filling pipe 30. At this time, the engaging portion 31 relies on the pulling force of the spring 312 to maintain the state of being engaged with the limiting portion 511.

[0053] Further exemplarily, at least one sealing member 53 is provided between the first end 51 of the connecting pipe 50 and the medium inlet 302 of the medium filling pipe 30. In this embodiment, a sealing member 53 is provided at each of the first end 51 of the connecting pipe 50 and the medium inlet 302 of the medium filling pipe 30, and when the engaging portion 31 is engaged with the limiting portion 511, the sealing member 53 is in a deformed state to improve the sealing effect between the connecting pipe 50 and the medium filling pipe 30 and improve the accuracy of pressure detection.

[0054] Figure 6 Shown in the figure is the structure diagram of another embodiment of the present disclosure Figure 3 of the present disclosure. In Figure 6In the example, the clamping portion 31A is threadedly connected to the corresponding side wall of the medium inlet 302 of the medium filling pipe 30. As the clamping portion 31A rotates, one end of the clamping portion 31A entering the accommodating cavity 304 is snap-fitted to the limiting portion 511. At this time, due to the self-locking property of the thread, the clamping portion 31A relies on the self-locking property of the thread to maintain the state of clamping the limiting portion 511. In this embodiment, the operating end 313A is implemented in a shape that facilitates the rotation of the clamping portion 31A.

[0055] In summary, the prostate pressure measurement system provided in the embodiments of the present disclosure is characterized by including: a catheter including a guide wire channel for a guide wire to penetrate and at least one medium channel; at least one balloon disposed around the catheter and near one end of the catheter, the medium channel communicating with the balloon; a medium filling pipe, one end connected to the catheter to form a medium outlet communicating with the medium channel, and the other end forming a medium inlet; a medium pressure gauge, its liquid outlet communicating with the medium inlet of the medium filling pipe, and its liquid inlet for medium injection; wherein when the medium flows through the medium pressure gauge, the pressure gauge can obtain the pressure of the medium injection; a connecting pipe, the first end is hermetically connected and sleeved with the medium inlet of the medium filling pipe, and the second end communicates with the liquid outlet of the medium pressure gauge; at least one limiting portion is provided on the side wall of the first end of the connecting pipe, and at least one clamping portion for snap-fitting with the limiting portion is provided on the corresponding side wall of the medium inlet of the medium filling pipe. The pressure of the medium injected into the balloon is detected by the medium pressure gauge, and the pressure of the prostate on the urethra is determined by the pressure in the balloon. Secondly, the snap-fitting of the clamping portion on the medium filling pipe and the limiting portion on the connecting pipe realizes the relative fixation of the first end of the connecting pipe and the medium inlet of the medium filling pipe, thereby avoiding the loosening or detachment of the connection between the connecting pipe and the medium filling pipe during the medium injection, and further improving the measurement effect and efficiency.
