Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, and relates to a urodynamic analyzer which is convenient for switching detection modes. Background Art

[0002] The urodynamic analyzer is based on the principles of fluid mechanics and uses sensor technology to transmit the measured bladder pressure, abdominal pressure, urethral pressure, etc. to the pressure sensor through the catheter. It can accurately capture data such as bladder pressure, abdominal pressure, urethral pressure, etc., such as the dynamic changes in pressure during bladder filling or urination. The pressure sensor converts the pressure signal into a weak electrical signal, which is amplified by the amplification channel and then converted into a digital signal by the analog-to-digital converter. The uroflowmeter measures the flow rate and flow of urine during urination based on principles such as gravity. Some are also equipped with electromyographic sensors that can detect the electromyographic activity of the urethral sphincter and pelvic floor muscles, and fully understand the state of urinary tract-related muscles. The computer then collects, processes, displays and prints the measured signals to provide key basis for doctors to formulate personalized treatment plans and guide decisions such as rational medication or surgical intervention.

[0003] At present, when measuring bladder pressure and urethral pressure, different pipelines need to be connected respectively, which requires workers to assemble different pipelines in different detection modes, which is time-consuming, labor-intensive, and prone to errors.

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] In a solution of a urodynamic analyzer fluid path connection conversion device disclosed in the patent document with publication number CN109009175B, in this solution, when the lower cover rotates, the two docking ports of the dual-chamber connection channel move along the rotation trajectory of the lower cover. Only when the lower cover rotates 180 degrees can the two docking ports be reconnected with the bladder pressure channel and the infusion socket. When deviation occurs, the socket on the upper side and the socket on the lower side will be in a misaligned state, causing liquid leakage. And because each connection channel is connected based on the rotation of the lower cover, it will cause leakage in each connection channel at the same time, causing the overall leakage to be superimposed, greatly affecting the accuracy of the pressure value. In order to solve the above problems, the following scheme is proposed:

[0039] like Figure 1-Figure 9 As shown, a urodynamic analyzer convenient for switching detection modes comprises a base 11, a body 1 is mounted on the upper end of the base 11, a connecting member 12 is mounted on the side wall of the body 1, the connecting member 12 can slide up and down on the body 1 to adjust the position, the connecting member 12 itself consists of two parts that can rotate relatively, so that the connecting member 12 can also rotate, so that the connecting member 12 has a greater degree of freedom, and a mode switching unit 2 is mounted on the connecting member 12. The mode switching unit 2 can switch back and forth between the bladder detection mode and the urethra detection mode.

[0040] The mode switching unit 2 includes a shell 3 , in which a first pipe 31 and a second pipe 32 are arranged. The first pipe 31 has a first butt end 311 and a second butt end 312 , and the second pipe 32 has a third butt end 321 , a fourth butt end 322 and a fifth butt end 323 .

[0041] In this embodiment, the first pipeline 31 is a straight pipe, and the second pipeline 32 is a three-way pipe.

[0042] Among them, the first docking end 311 is connected to the bladder pressure sensor, the third docking end 321 is connected to the water outlet end of the perfusion pump, the fourth docking end 322 is connected to the urethra pressure sensor, and the second docking end 312 and the fifth docking end 323 are respectively connected to the two external connectors of the double-lumen tube.

[0043] The housing 3 has a cavity 33 in which a closing plate 5 is slidably disposed. The front and rear ends of the cavity 33 are both provided with limiting openings. Both ends of the closing plate 5 are slidably disposed in the limiting openings. The closing plate 5 slides horizontally back and forth in the cavity 33, and the length of the closing plate 5 is greater than the distance between the two limiting openings, so that a part of the closing plate 5 is always located outside the housing 3. The closing plate 5 acts on the fourth docking end 322. Specifically, the closing plate 5 always slides on the upper end of the fourth docking end 322. When the machine body 1 is performing bladder pressure detection, the closing plate 5 closes the fourth docking end 322. When the machine body 1 is performing urethral pressure detection, the closing plate 5 opens the fourth docking end 322.

[0044] Compared with the existing analyzer, in this embodiment, since the first pipe 31 is a straight pipe and the second pipe 32 is a three-way pipe, when in use, the first butt end 311 and the second butt end 312 of the first pipe 31 are always connected together, and the third butt end 321, the fourth butt end, and the fifth butt end 323 of the second pipe 32 are also always connected together. In different modes, the first butt end 311 is always connected to the bladder pressure sensor, the second butt end 312 and the fifth butt end 323 are always connected to the two external connectors of the double-lumen tube, and the third butt end 321 is always connected to the water outlet of the perfusion pump. In different modes, it is only necessary to control the opening and closing of the fourth butt end 322 to achieve mode switching.

[0045] By such arrangement, when switching modes, it is not necessary to consider the docking of multiple pipelines at the same time, thereby greatly improving the airtightness of each pipeline. At the same time, since the relative positions of the housing 3 and the first pipeline 31 and the second pipeline 32 remain unchanged, the positions of the various connecting pipes connected to the housing 3 also remain unchanged, so when switching modes, the various connecting pipes will not be entangled with each other, which is conducive to the staff to quickly sort out the connection of the pipelines.

[0046] In order to realize the opening and closing of the fourth docking end 322, a docking port 51 is provided on the closing plate 5, and the closing plate 5 can slide to the first position or the second position in the cavity 33. The first position is that the closing plate 5 is located at the rightmost end, and the second position is that the closing plate 5 is located at the leftmost end. When the closing plate 5 is located at the first position, the docking port 51 is aligned with the fourth docking end 322, so that the fourth docking end 322 is in an open state. When the closing plate 5 is in the second position, the docking port 51 is misaligned with the fourth docking end 322, so that the fourth docking end 322 is in a closed state. That is to say, in this embodiment, the opening and closing control of the fourth docking end 322 is realized by adjusting the position of the closing plate 5 and controlling the docking port 51 to overlap or misalign with the fourth docking end 322. This control method does not require a large adjustment of the shell 3, and only requires adjusting the position of the closing plate 5, which is simple and convenient to operate.

[0047] In order to facilitate the insertion of the pipeline and allow a certain degree of fault tolerance in the docking process, an annular wall 511 which is larger at the top and smaller at the bottom is provided at the upper end of the docking port 51. When the pipeline is inserted downward, it is easier to fall into the range of the annular wall. As the pipeline continues to move downward, the inclined side wall of the annular wall 511 allows the pipeline to smoothly enter the docking port 51, thereby achieving a quick connection between the pipeline and the docking port 51.

[0048] In order to ensure stable sliding between the closing plate 5 and the second pipe 32, a closing groove 53 is provided at the lower end of the closing plate 5. The closing groove 53 is in a long strip shape, and one end of the closing groove 53 is connected to the lower part of the docking port 51. When the closing plate 5 slides back and forth, the fourth docking end 322 of the second pipe 32 always slides in the closing groove 53, thereby preventing relative displacement between the closing plate 5 and the fourth docking end 322.

[0049] The middle part of the upper side wall of the closed groove 53 has an inclined guide wall 532, and the end of the guide wall 532 close to the docking port 51 is higher than the end away from the docking port 51. The end of the closed groove 53 away from the docking port 51 has an abutment wall 531, and the abutment wall 531 is connected to the guide wall 532. That is, as the closed plate 5 slides, the distance from the upper end of the fourth docking end 322 to the upper side wall of the closed groove 53 is not fixed, but will change.

[0050] When the closing plate 5 is in the second position, the upper end of the fourth butt end 322 is in airtight contact with the lower side wall of the abutting wall 531 to ensure the closure of the fourth butt end 322. As the closing plate 5 moves, when the fourth butt end 322 moves to the position of the guide wall 532, the fourth butt end 322 gradually moves away from the upper side wall of the closing groove 53 as the closing plate 5 moves, thereby reducing the friction resistance generated by the closing plate 5 and the fourth butt end 322 during the movement. When the closing plate 5 is in the first position, the upper end of the fourth butt end 322 is located in the docking port 51.

[0051] Through the arrangement of the above-mentioned mechanism, this embodiment can reduce the frictional resistance of movement while ensuring the airtightness between the closing plate 5 and the fourth docking end 322, thereby making the switching between the two modes easier and achieving a better airtightness.

[0052] Furthermore, the present embodiment further comprises a mounting frame 21, through which the housing 3 is fixedly connected to the side wall of the connecting member 12, and a telescopic cylinder 22 is fixedly mounted on the mounting frame 21, and the driving direction of the telescopic cylinder 22 is along the vertical direction. Specifically, the telescopic cylinder 22 can be an electric cylinder, a hydraulic cylinder or a pneumatic cylinder. A clamping plate 23 is fixedly connected to the output end of the telescopic cylinder 22, and a clamping groove 231 is provided at the front end of the clamping plate 23. The clamping groove 231 is used to clamp the cannula 4 of the urethral pressure sensor. The clamping groove 231 is specifically a semicircular structure and can be made of elastic plastic material so that the end of the clamping groove 231 can be deformed to facilitate fixing or removing the cannula 4 from the clamping groove 231. Furthermore, a matching limiting ring 41 is fixedly connected to the insert tube 4, and the limiting ring 41 can cooperate with the clamping groove 231 to achieve limiting fixation of the insert tube 4, so as to facilitate the insert tube 4 to move up and down through the clamping plate 23 to achieve automatic insertion and removal of the insert tube 4.

[0053] Specifically, when the telescopic cylinder 22 is started, the cannula 4 can be driven to move up and down through the clamping groove 231 , so that the cannula 4 is inserted into or pulled out of the fourth docking end 322 .

[0054] A sleeve 34 is fixedly inserted in the housing 3, the upper end of the sleeve 34 is an insertion end 341, the lower end of the sleeve 34 is arranged opposite to the fourth docking end 322, and the closing plate 5 is slidably arranged between the sleeve 34 and the fourth docking end 322. When the closing plate 5 moves, the sleeve 34 and the fourth docking end 322 can be connected or separated. The sleeve 34 plays a guiding role, so that the insertion tube 4 is inserted downward along the sleeve 34.

[0055] In this embodiment, the lower end of the clamping plate 23 is fixedly connected with a driving bar 24, which is arranged vertically. A driving groove is provided on the driving bar 24, which is arranged along the length direction of the driving bar 24 and also along the vertical direction. The starting point and the end point of the driving groove are at different distances from the housing 3. In one embodiment, the driving groove is arranged obliquely, so that there is a displacement difference between the starting point and the end point of the driving groove in the horizontal direction. A driving column 52 is fixedly connected to the side wall of the closing plate 5, and the driving column 52 is slidably connected in the driving groove. When the clamping plate 23 drives the driving bar 24 to move up and down, the driving groove acts on the driving column 52 to drive the closing plate 5 to move back and forth. That is, the driving bar 24 moves up and down, and the horizontal movement of the closing plate 5 is achieved through the interaction between the driving column 52 and the driving groove.

[0056] In order to improve stability, there are two driving bars 24, and the two driving bars 24 are respectively arranged on both sides of the clamping plate 23, and there are two groups of driving columns 52. The two groups of driving columns 52 are respectively slidably arranged in the driving grooves on the two driving bars 24, so that both sides of the closing plate 5 are subjected to force at the same time, thereby avoiding the closing plate 5 from tilting due to uneven force.

[0057] It should be further explained that, in this embodiment, the driving groove includes a first strip groove 241, a second strip groove 242 and a third strip groove 243, wherein the first strip groove 241 and the third strip groove 243 are both vertically arranged, and the first strip groove 241 is arranged away from the shell 3, the third strip groove 243 is arranged close to the shell 3, and the second strip groove 242 is inclined to connect the first strip groove 241 and the second strip groove 242.

[0058] When the driving column 52 is located in the first strip groove 241, the closing plate 5 is at the rightmost position, and the closing plate 5 opens the fourth docking end 322. When the driving column 52 is located in the third strip groove 243, the closing plate 5 is at the leftmost position, and the closing plate 5 closes the fourth docking end 322.

[0059] As a further optimization, the length of the first strip groove 241 is equal to the insertion depth of the cannula 4, that is, when the cannula 4 is fully inserted into the fourth docking end 322, the driving column 52 moves to the uppermost end of the first strip groove 241. On the one hand, the first strip groove 241 can limit the horizontal direction of the driving column 52 to prevent the closing plate 5 from continuing to slide in the horizontal direction, thereby ensuring that the docking port 51 can be aligned and connected with the fourth docking end 322. On the other hand, the driving column 52 can limit the vertical direction of the first strip groove 241 to prevent the cannula 4 from continuing to move in the vertical direction, ensuring that the cannula 4 and the fourth docking end 322 can be tightly docked.

[0060] Through the cooperation among the driving groove, the clamping plate 23, the insert tube 4 and the closing plate 5, a double limit can be formed to ensure the deep locking of the insert tube 4 and the fourth docking end 322, thereby improving the airtightness of the connection between the pipelines.

[0061] As a further optimization, the lower end of the third strip groove 243 is open, and in normal working state, when the telescopic cylinder 22 controls the driving bar 24 to move upward, the driving column 52 will not be separated from the third strip groove 243, so that the driving column 52 can be limited by the third strip groove 243. When disassembly and maintenance are required, the clamping plate 23 is controlled by the telescopic cylinder 22 to continue to move upward until the driving column 52 is separated from the third strip groove 243.

[0062] Here’s how it works:

[0063] In the initial state, the telescopic cylinder 22 is in a shortened state, the driving column 52 is located in the third strip groove 243, and the docking port 51 on the closing plate 5 is misaligned with the fourth docking end 322, so that the fourth docking end 322 is in a closed state.

[0064] When performing bladder pressure detection, water flows out from the water outlet of the infusion pump, and the water enters the double-lumen pressure measuring tube through the third docking end 321 and the fifth docking end 323 in turn. Then, the bladder pressure information enters the second docking end 312 and the first docking end 311 through the double-lumen pressure measuring tube in turn and is transmitted to the bladder pressure sensor. The bladder pressure sensor transmits the measured information to the body 1 to realize pressure detection.

[0065] When performing urethral pressure detection, it is necessary to control the telescopic cylinder 22 to extend downward. When the telescopic cylinder 22 extends downward, it will drive the clamping plate 23 to move downward. On the one hand, the clamping plate 23 drives the driving bar 24 to move downward, so that the driving groove acts on the driving column 52, thereby pushing the closing plate 5 to move backward, so that the docking port 51 is aligned with the fourth docking end 322, so that the fourth docking end 322 is in an open state. On the other hand, the clamping plate 23 drives the cannula 4 to move downward, so that the cannula 4 passes through the sleeve 34 and is inserted into the fourth docking end 322 in the open state, so that the fourth docking end 322 docks with the urethral pressure sensor.

[0066] It should be noted that when the fourth docking end 322 is in the open state, there is still sliding space on the upper part of the first strip groove 241, so that the insertion tube 4 can continue to move downward to avoid interference.

[0067] After the water comes out of the water outlet of the infusion pump, on the one hand, the water will transmit the pressure information to the bladder pressure sensor through the double-lumen pressure measuring tube and the first pipe 31, and on the other hand, the water will transmit the pressure information to the urethra pressure sensor through the second pipe 32 to realize the detection of urethra pressure.

[0068] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
