Description

Technical Field

[0001] This utility model relates to the technical field of urination function testing equipment, and in particular to a non-invasive urodynamic testing device. Background Technology

[0002] Currently, when assessing bladder voiding function using urodynamics, conventional urodynamics is used to measure bladder pressure. This involves inserting a pressure measuring tube into the subject's bladder to establish a channel, and then performing an invasive examination by infusing a medium of gas or liquid from outside the body. During the urodynamic examination, the pressure measuring tube is in the intubated state, which occupies urethral space and stimulates the urethra, making it difficult to truly simulate the subject's normal voiding state.

[0003] The above-mentioned measurement methods are somewhat invasive and unnatural, and may cause problems such as urethral pressure data drift and difficulty in fixing the pressure measuring tube. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a non-invasive urodynamic testing device that enables urodynamic testing without invasive procedures.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] This invention provides a non-invasive urodynamic testing device, including a free arm, a uroflowmeter, and a uroflowmeter mechanism for detecting urine flow rate; the uroflowmeter mechanism is connected to the movable end of the free arm so that the urine inlet of the uroflowmeter mechanism corresponds to the urethral opening of the subject; the urine outlet of the uroflowmeter mechanism corresponds to the detection inlet of the uroflowmeter.

[0007] Furthermore, the urine flow rate mechanism includes a urine flow rate meter, a mounting base, a guide tube, and a funnel for connecting a disposable catheter. The mounting base has an installation channel extending through its upper and lower surfaces. The circumferential wall of the installation channel has an installation port for inserting the urine flow rate meter. The guide tube is fitted onto one end of the installation channel to form a sealed fit. The funnel is inserted into the other end of the installation channel opposite to the guide tube. The urine flow rate meter is inserted into the installation port, and the detection blade of the urine flow rate meter is located between the funnel and the guide tube, corresponding to the urine outlet of the funnel. The inlet of the disposable catheter is the urine inlet detection port of the urine flow rate mechanism. The outlet of the guide tube is the urine outlet of the urine flow rate mechanism.

[0008] Furthermore, a leak-proof ring is provided inside the end of the guide tube facing the mounting base to form a sealed fit between the guide tube, the urine flow meter, and the mounting base.

[0009] Furthermore, the free arm includes a vertical rod, multiple support arms, and joints for rotation. The joints are respectively provided between two adjacent support arms, between the vertical rod and the support arms, and between the urine flow rate mechanism and the support arms, so that the urine flow rate mechanism has multiple degrees of freedom. The joint on the support arm near the urine flow rate mechanism is the movable end of the free arm.

[0010] Furthermore, the joint includes a pin and two rotating members spaced apart. Each rotating member has a pin hole, and the pin is movably inserted through the pin holes of the two rotating members so that the two rotating members can rotate relative to each other.

[0011] Furthermore, a first rigid washer is provided between the two rotating parts, and an adjusting nut for adjusting the rotation tightness of the rotating parts is provided on the pin.

[0012] Furthermore, an elastic element is provided between the rotating component and the adjusting nut; and / or, a second rigid washer is provided between the pin and the rotating component.

[0013] Furthermore, the elastic element is a deformation gasket.

[0014] Furthermore, the number of joints is four, and the number of support arms is three, so that the urine flow rate mechanism can move forward and backward, left and right, up and down, and tilt.

[0015] Furthermore, the rotating component is a disk.

[0016] The technical solution provided by this utility model has the following beneficial effects:

[0017] The movable end of the free arm drives the urine flow rate mechanism to align the urine inlet of the urine flow rate mechanism with the urethral opening of the subject. After the subject's urine stream passes through the urine inlet of the urine flow rate mechanism, the urine flow rate is first detected to determine the maximum urine flow rate. Then, the urine stream flows into the detection inlet of the urine flow rate meter through the urine outlet of the urine flow rate mechanism, and the maximum urine flow rate is determined by the urine flow rate meter. In this way, urodynamic testing can be performed non-invasively, and the subject's normal urination state can be simulated to obtain accurate and stable urethral opening pressure data. It can also avoid problems such as difficulty in fixing the pressure measuring tube in existing measurement methods. Attached Figure Description

[0023] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0025] Reference Figures 1 to 5 As shown, this embodiment provides a non-invasive urodynamic testing device (hereinafter referred to as the testing device) for detecting the maximum urine flow rate and urine flow rate of the subject, thereby assisting in the assessment of the subject's bladder emptying function.

[0026] like Figure 1 and Figure 2 As shown, the detection device in this embodiment includes a free arm 1, a urine flow rate meter 3, and a urine flow rate mechanism 2 for detecting urine flow rate. The urine outlet of the urine flow rate mechanism 2 corresponds to the detection inlet of the urine flow rate meter 3, and the urine flow rate mechanism 2 is connected to the movable end of the free arm 1 so that the urine inlet detection port of the urine flow rate mechanism 2 corresponds to the urethral opening of the subject.

[0027] like Figure 3 and Figure 4 As shown, in this embodiment, the urine flow rate mechanism 2 includes a urine flow rate meter 21, a mounting base 22, a guide tube 23, and a funnel 24 for connecting a disposable catheter 25. The mounting base 22 has an installation channel 221 extending through its upper and lower surfaces. The circumferential wall of the installation channel 221 has an installation port 222 for inserting the urine flow rate meter 21. The guide tube 23 is fitted onto the lower end of the installation channel 221 and forms a sealed fit. The funnel 24 is inserted into the upper end of the installation channel 221 away from the guide tube 23.

[0028] The urine flow meter 21 is inserted into the mounting port 222 located in the middle, so that the detection blade of the urine flow meter 21 is positioned between the funnel 24 and the guide tube 23. During detection, the urine stream flowing out of the urine outlet of the funnel 24 is directed towards the detection blade of the urine flow meter 21 and generates an impact force to drive the detection blade to rotate.

[0029] A leak-proof ring 231 is provided inside the upper end of the guide tube 23 facing the mounting base 22 to form a sealed fit between the guide tube 23, the urine flow meter 21 and the mounting base 22 to prevent urine leakage.

[0030] In this embodiment, when the detection device is in use, the disposable catheter 25 is detachably inserted into the funnel 24, the urine flow meter 3 is located below the urine flow rate mechanism 2, and the urine of the subject is introduced through the disposable catheter 25, and flows through the funnel 24, the detection blade of the urine flow meter 21 and the guide tube 23 in sequence. Finally, the urine flows out from the outlet of the guide tube 23 and continues to flow into the detection inlet of the urine flow meter 3. At this time, the inlet of the disposable catheter 25 is the urine inlet detection port of the urine flow rate mechanism 2, and the outlet of the guide tube 23 is the urine outlet of the urine flow rate mechanism 2.

[0031] In another preferred embodiment, such as Figure 1 As shown, the free arm 1 includes one upright 11, three support arms 12, and four joints 13 for rotation, as follows: Figure 2 As shown, the three support arms 12 are the first horizontal support arm 121, the second vertical support arm 122, and the third vertical support arm 123.

[0032] In specific implementation, a horizontally arranged fixing seat 111 is installed on the upright 11. The extension direction of the fixing seat 111 is parallel to the extension direction of the first horizontal support arm 121. A first joint is provided between the fixing seat 111 and the first horizontal support arm 121, and the first horizontal support arm 121 can rotate along the joint surface of the first joint through the first joint.

[0033] A second joint is provided between the end of the first transverse support arm 121 away from the fixed base 111 and the second longitudinal support arm 122, and the second longitudinal support arm 122 can rotate along the joint surface of the second joint through the second joint.

[0034] A third joint is provided between the end of the second longitudinal support arm 122 away from the first transverse support arm 121 and the third longitudinal support arm 123, and the third longitudinal support arm 123 can rotate along the joint surface of the third joint through the third joint.

[0035] like Figure 2 and Figure 3As shown, the outer peripheral wall of the mounting base 22 has mounting blocks 223 extending vertically upward and downward. A fourth joint is provided between the end of the third longitudinal support arm 123 away from the second longitudinal support arm 122 and the mounting block 223 of the mounting base 22. The urine flow rate mechanism 2 is rotated along the joint surface of the fourth joint through the fourth joint. At this time, the fourth joint is the movable end of the free arm 1.

[0036] Through the combined action of three support arms 12 and four joints 13, the urine flow rate mechanism 2 has multiple degrees of freedom, that is, the urine flow rate mechanism 2 has degrees of freedom to move forward, backward, left, right, up, down and tilt under the drive of the free arm 1.

[0037] When the detection device of this embodiment is needed for urodynamic testing, the disposable catheter 25 is first moved to the perineum of the subject through the free arm 1, ensuring that the subject's urethral opening is aligned with the inlet of the disposable catheter 25. At the same time, the outlet of the lower end of the guide tube 23 of the urine flow rate mechanism 2 is aligned with the detection inlet of the urine flow rate meter 3. Then, the subject's urine stream passes through the disposable catheter 25 and the funnel 24, and then impacts the detection blade of the urine flow rate meter 21. At this time, the subject's maximum urine flow rate can be measured. Then, the urine flows into the urine flow rate meter 3 through the guide tube 23, and the subject's maximum urine flow rate can be detected. In this way, the subject's maximum urine flow rate and maximum urine flow rate can be measured simultaneously.

[0038] The movable end of the free arm 1 drives the urine flow rate mechanism 2 to align the urine inlet of the urine flow rate mechanism 2 with the urethral opening of the subject. After the subject's urine stream passes through the urine inlet of the urine flow rate mechanism 2, the urine flow rate is first detected to determine the maximum urine flow rate. Then, the urine stream flows through the outlet of the urine flow rate mechanism 2 into the detection inlet of the uroflowmeter 3, and the maximum urine flow rate is determined by the uroflowmeter 3. This allows for urodynamic testing without invasive procedures and can simulate the subject's normal urination state to obtain accurate and stable urethral opening pressure data. It also avoids problems such as difficulty in fixing the pressure measuring tube in existing measurement methods.

[0039] More specifically, such as Figure 5 As shown, the joint 13 includes a pin 131 and two rotating members 132 that are spaced apart. Both rotating members 132 have pin holes 133. The pin 131 is movably inserted through the pin holes 133 of the two rotating members 132 so that the two rotating members 132 can rotate relative to each other.

[0040] In this specific embodiment, the two rotating components 132 are a first disk and a second disk, respectively. A first rigid washer 134 is provided between the first disk and the second disk. An adjusting nut 136 for adjusting the rotation tightness of the rotating component 132 is provided on one end of the pin 131. The adjusting nut 136 is located in the pin hole 133 of the first disk. An elastic element 137 and a second rigid washer 135 are provided between the first disk and the adjusting nut 136. A second rigid washer 135 is also provided between the head of the pin 131 located in the second disk and the second disk. Specifically, the elastic element 137 is a deformation washer for providing elastic force restriction, and it works in conjunction with the adjusting nut 136 to adjust the rotation tightness. In this way, the first disk and the second disk can rotate relative to each other and form a reliable joint structure.

[0041] Of course, in other embodiments, the rotating member 132 may also be pentagonal, hexagonal, or other shapes. Furthermore, the deformation washer may be replaced by a spring.

[0042] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
