Description

Technical Field

[0001] This utility model relates to the field of medical and nursing technology, specifically a pressure testing device for assessing the strength of male pelvic floor muscles. Background Technology

[0002] The pelvic floor muscles are the group of muscles that close the bottom of the pelvis. Organs such as the urethra, bladder, vagina, uterus, and rectum are located within these muscles, maintaining their proper position and function. However, with age, the pelvic floor muscles gradually weaken, causing organs to lose their proper position and leading to functional disorders. This is especially true in the elderly, where weakened pelvic floor muscles can easily result in urinary and fecal incontinence, organ prolapse, and other problems. Therefore, it is necessary to train the pelvic floor muscles daily to maintain their contraction strength and to periodically assess their muscle strength using a pelvic floor muscle strength and pressure monitoring device.

[0003] A search revealed a pressure detection device for assessing the strength of female pelvic floor muscles, disclosed in Chinese Patent Publication No. CN111839554A. This device utilizes a pressure-sensing airbag; changes in air pressure cause the airbag to output gas through an air delivery tube. The air delivery tube guides the gas from the airbag to an airflow pressure sensor, which outputs a measurement signal based on the airflow pressure from the airbag, thus measuring the pressure feedback muscle strength value of the pelvic floor muscles in real time. This pressure detection device can accurately measure the initial static pressure muscle strength value, the contraction pressure value, and the relaxation pressure value of the pelvic floor muscles.

[0004] However, due to the tortuous structure of the human rectum, when the pressure detection device for pelvic floor muscle strength is used for testing male rectal pelvic floor muscles, it cannot adaptively fill the rectal structure and cannot ensure that the detection balloon and electromyographic elements are covered and in close contact with the rectal skin. Therefore, it is easy to cause inaccurate detection data. Hence, a pressure detection device for evaluating male pelvic floor muscle strength is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a pressure testing device for assessing male pelvic floor muscle strength. It has the advantage of being able to easily adjust the fit between the testing device and the rectal skin, thus solving the problem that existing pelvic floor muscle strength pressure testing devices, once inserted into the rectum, cannot adjust the degree of fit with the rectum, and are prone to inaccurate pressure testing data when the rectum exerts force.

[0006] To achieve the above-mentioned purpose of conveniently adjusting the fit between the detection device and the rectal skin, this utility model provides the following technical solution: a pressure detection device for evaluating the strength of male pelvic floor muscles, comprising a detection rod consisting of an end head and an end rod, wherein a testing mechanism is provided inside the detection rod and a driving mechanism is provided outside the detection rod;

[0008] The drive mechanism includes a mounting bracket fixed to the outside of the end rod. A transmission gear is rotatably connected to one side of the mounting bracket that is connected to the outside of the end rod. A gear rod is rotatably connected to the inside of the mounting bracket. A micro motor is fixedly installed on the left side of the mounting bracket.

[0009] Preferably, a handle plate is fixedly connected to one end of the end head and the end rod, and an anti-slip component is fixed to the top of the handle plate. The anti-slip component includes a soft silicone plug fixed to the top of the handle plate, and threaded rings are evenly distributed on the outer side of the soft silicone plug.

[0010] Preferably, the inner left and inner right walls of the end are provided with slots, the number of supporting arc plates is two, and they are respectively located inside the two slots. The number of swing rods and threaded screws is two, and the two threaded screws are threaded to the outside of the two screws. The two swing rods are respectively connected to the two lifting rings at the ends away from the supporting arc plates. The protective layer is an HDPE film structure, and the number of piezoelectric plates is six, which are evenly distributed in a ring array on the inner side of the capsule.

[0011] Preferably, there are two gas delivery conduits, and both gas delivery conduits are connected to the top of the second balloon at the end away from the first balloon. The strain gauge layer includes a base layer attached to the outside of the second balloon, and a cover layer is bonded to the outer layer of the base layer. A sensitive grid is bonded to the gap between the cover layer and the base layer.

[0012] Preferably, a miniature digital display screen is embedded at the bottom front of the end rod. The miniature digital display screen is equipped with a chip module. The chip module includes a bridge circuit and a first amplifier that are electrically connected to each other. The sensitive grid and the piezoelectric element are both connected to leads and are electrically connected to the bridge circuit. The first amplifier is electrically connected to the miniature digital display screen through a control circuit.

[0013] Preferably, a terminal block is provided on the inner rear wall of the end rod, and an electromyography (EMG) detector is externally connected to the inside of the terminal block via a cable. There are two electrode pads, and a wire is connected to one side of each of the two electrode pads. A second amplifier and an averager are electrically connected to each other inside the terminal block. The wire is electrically connected to the second amplifier. A lithium battery compartment is fixedly connected to the bottom of the end rod, and the lithium battery compartment is electrically connected to a micro digital display screen.

[0014] Preferably, a first bevel gear is coaxially fixed to the bottom of each of the two threaded screws. There are two transmission gears, which are located on the left and right sides of the end rod, respectively. A second bevel gear is coaxially fixed to the opposite end of each of the two transmission gears. The two second bevel gears mesh with the bottom of the two first bevel gears, respectively. An active gear that meshes with the two transmission gears is provided on the outside of the gear rod. The output shaft of the micro motor is coaxially fixed to the left end of the gear rod, and the micro motor is electrically connected to the lithium battery compartment.

[0015] Compared with the prior art, this utility model provides a pressure detection device for assessing the strength of male pelvic floor muscles, which has the following beneficial effects:

[0016] 1. This pressure detection device for assessing the strength of male pelvic floor muscles uses a micro motor to drive a gear rod, which in turn meshes with a transmission gear. The transmission gear meshes with a first bevel gear via a second bevel gear, controlling the rotation of a threaded screw. The threaded screw then drives a swing arm to oscillate, adjusting the fit between the support arc plate and the rectal skin. This ensures that the rectal skin stably covers the first balloon, thereby improving the accuracy of pressure data detection.

[0017] 2. This pressure testing device for assessing male pelvic floor muscle strength involves setting an end that enters the rectum. The rectal cavity encloses the end, and when the patient contracts the rectal muscles, the first balloon is compressed. Based on the air pressure balance characteristic, the second balloon expands. A strain gauge layer is laid on the outside of the second balloon, which causes the sensitive grid to deform and compress the piezoelectric element. The change in the output voltage of the connected bridge is measured, thereby determining the pressure change on the strain gauge layer and facilitating the assessment of muscle strength.

[0018] 3. This pressure testing device for assessing male pelvic floor muscle strength uses an electrode plate installed at the end and an external electromyography (EMG) instrument connected via a connector and cable to collect EMG and muscle strength data. The end and soft silicone plug are wrapped around the rectal cavity, which adapts to the rectal cavity structure and effectively reduces the feeling of a foreign body. The flexible soft silicone plug and threaded ring adapt to the rectal cavity structure, avoiding inaccurate measurement data due to the probe falling off during measurement.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-8 A pressure testing device for assessing the strength of male pelvic floor muscles includes a testing rod 1 consisting of an end 101 and an end bar 102. The testing rod 1 has a testing mechanism 2 inside and a driving mechanism 3 outside.

[0030] The testing mechanism 2 includes a support arc plate 201 rotatably connected to the inside of the end 101. A first balloon 202 is fixedly connected to the inside of the support arc plate 201. A gas delivery conduit 203 is fixedly connected to the side of the first balloon 202 facing the inside of the end 101. A swing rod 204 is hinged to the inside of the support arc plate 201. A sliding seat 205 is fixedly connected to the inside of the end 101. A threaded screw 206 is rotatably connected to the inside of the sliding seat 205. A protective layer 207 covers the outside of the first balloon 202. A balloon cylinder 208 is fixedly connected to the inside of the end rod 102. A piezoelectric sheet 209 is provided on the inside of the balloon cylinder 208. A second balloon 210 is filled inside the balloon cylinder 208. A strain gauge layer 211 is laid on the outside of the second balloon 210. An electrode sheet 212 is fixedly installed on the inside of the first balloon 202.

[0031] The drive mechanism 3 includes a mounting bracket 301 fixed to the outside of the end rod 102. A transmission gear 302 is rotatably connected to the side of the mounting bracket 301 that is connected to the outside of the end rod 102. A gear rod 303 is rotatably connected to the inside of the mounting bracket 301. A micro motor 304 is fixedly mounted on the left side of the mounting bracket 301.

[0032] Furthermore, a handle plate is fixedly connected to one end of the end 101 and the end rod 102. An anti-detachment component 4 is fixed to the top of the handle plate. The anti-detachment component 4 includes a soft silicone plug 401 fixed to the top of the handle plate. Threaded rings 402 are evenly distributed on the outer side of the soft silicone plug 401.

[0033] Specifically, the end 101 is inserted into the patient's rectal lumen using the handle plate. At this time, the soft silicone plug 401, made of flexible material, will fill and adapt to the structure of the rectal lumen, allowing the rectal lumen to cover the end 101. The threaded ring 402 is used to increase friction, preventing the detection end from falling off when the patient contracts the rectal muscle group because it cannot adapt to the structure of the rectal lumen.

[0034] Furthermore, the inner left and inner right walls of the end 101 are provided with slots, and there are two supporting arc plates 201, which are located inside the two slots respectively. There are two swing rods 204 and two threaded screws 206. The two threaded screws 206 are threaded with lifting rings on their outer sides. The two swing rods 204 are connected to the two lifting rings at the ends away from the supporting arc plates 201 respectively. The protective layer 207 is an HDPE film structure, and there are six piezoelectric sheets 209, which are evenly distributed in a ring array on the inner side of the capsule 208.

[0035] Specifically, after the tip 101 is inserted into the rectum and covered by the rectal lumen, the inner skin of the rectum will closely adhere to the outer side of the first balloon 202. At this time, the protective layer 207 of the HDPE membrane structure maintains the comfort of contact with the skin and improves the wear resistance of the first balloon 202.

[0036] The threaded screw 206 drives the lifting ring to move up and down, and controls the swing arm 204 to drive the support arc plate 201 to change angle. Based on the piezoelectric effect, the piezoelectric plate 209 converts the pressure of the second balloon 210 when it expands into a voltage signal and transmits the voltage signal to the bridge, thereby causing the bridge to lose balance and its output voltage to change.

[0037] Furthermore, there are two gas delivery conduits 203. Both gas delivery conduits 203 are connected to the top of the second balloon 210 at the end away from the first balloon 202. The strain gauge layer 211 includes a base layer 2111 attached to the outside of the second balloon 210. A cover layer 2112 is bonded to the outer layer of the base layer 2111. A sensitive grid 2113 is bonded to the gap between the cover layer 2112 and the base layer 2111.

[0038] Specifically, by the patient contracting the rectal muscle group, the rectal lumen skin will squeeze the first balloons 202 on both sides, causing the first balloons 202 to contract and send gas into the second balloon 210 through the gas delivery tube 203, thereby causing the second balloon 210 to inflate.

[0039] Furthermore, a miniature digital display screen is embedded at the bottom front of the end rod 102. The miniature digital display screen is equipped with a chip module. The chip module includes a bridge and a first amplifier that are electrically connected to each other. The sensitive grid 2113 and the piezoelectric sheet 209 are both connected to leads and are electrically connected to the bridge. The first amplifier is electrically connected to the miniature digital display screen through a control circuit.

[0040] Specifically, the second balloon 210 expands, thereby causing the strain gauge layer 211 on its outer side to deform. When the sensitive grid 2113 deforms, its resistance value will change accordingly. The calculation formula for the principle of resistance change is: R=ρ*A / L, where R is the resistance, ρ is the resistivity, L is the material length, and A is the cross-sectional area.

[0041] Therefore, when subjected to tensile or compressive stress, its length L will change, and its cross-sectional area A may also change, resulting in a change in the resistance value R.

[0042] Furthermore, there are two electrode pads 212, and each electrode pad 212 has a wire connected to one side. The terminal block 7 is equipped with a second amplifier and an averager that are electrically connected to each other. The wire is electrically connected to the second amplifier. The terminal block 7 is provided on the inner rear wall of the end rod 102. The electromyography detector 8 is externally connected to the inside of the terminal block 7 through a cable. The bottom of the end rod 102 is fixedly connected to a lithium battery compartment 9, which is electrically connected to a micro digital display screen.

[0043] Specifically, the sensitive grid 2113 is electrically connected to the bridge via leads. At this time, the sensitive grid 2113 deforms, causing a change in resistance, which causes the bridge to lose balance and its output voltage to change. The changed voltage data is amplified by the first amplifier and then received by the chip module of the micro digital display screen. The logic algorithm calculates the change data of the pressure on the sensitive grid 2113 and displays it on the screen of the micro digital display screen.

[0044] When the rectal lumen skin covers the end 101, the electrode pads 212 on both sides will contact the lumen skin. When the patient contracts the rectal muscle group, the muscle fibers are stimulated by nerve impulses, which will generate corresponding potential changes. The potential changes are captured by the electrode pads 212, amplified by the second amplifier, and then received by the averager.

[0045] The averager transmits the received electrical signals to the external electromyography (EMG) detector 8, where they are converted into visualized waveforms. By analyzing the waveforms, the electrical activity patterns of the muscles can be assessed, including the muscle's contractile ability and coordination.

[0046] The miniature digital display screen incorporates a muscle strength rating standard. Based on the strength of the pelvic floor muscles, a graded system is established to assess the intensity and duration of pelvic floor muscle contractions. The pelvic floor muscle strength includes:

[0047] 1) Level 0: In a relaxed state, with no contraction;

[0048] 2) Grade 1: In a state of slight contraction, but without a significant increase in muscle strength;

[0049] 3) Grade 2: In a certain state of contraction, muscle strength is significantly increased, but muscle groups are weak;

[0050] 4) Level 3: The body is in a state of strong contraction, but cannot resist applied mild pressure;

[0051] 5) Level 4: In a state of strong contraction, able to resist mild pressure;

[0052] 6) Level 5: In a state of strong contraction, able to resist moderate pressure.

[0053] Furthermore, the bottom of each of the two threaded screws 206 is coaxially fixed with a first bevel gear 10, and there are two transmission gears 302, which are located on the left and right sides of the end rod 102 respectively. The opposite ends of the two transmission gears 302 are coaxially fixed with a second bevel gear 11. The two second bevel gears 11 mesh with the bottom of the two first bevel gears 10 respectively. The gear rod 303 is provided with a drive gear that meshes with the two transmission gears 302. The output shaft of the micro motor 304 is coaxially fixed with the left end of the gear rod 303, and the micro motor 304 is electrically connected to the lithium battery compartment 9.

[0054] Specifically, the micro motor 304 drives the gear rod 303, and the active gear on the gear rod 303 meshes with and drives the two transmission gears 302 respectively, thereby controlling the transmission gears 302 to drive the threaded screw 206 to rotate through the first bevel gear 10 and the second bevel gear 11.

[0055] In summary, this pressure detection device for assessing male pelvic floor muscle strength uses a micro motor 304 to drive a gear rod 303, which in turn meshes with a transmission gear 302. The transmission gear 302 meshes with a first bevel gear 10 via a second bevel gear 11, controlling the rotation of a threaded screw 206. The threaded screw 206 then drives a swing arm 204 to oscillate at an angle, adjusting the fit between the support arc plate 201 and the rectal skin to ensure stable coverage of the first balloon 202 by the rectal skin, thereby improving the accuracy of pressure data detection.

[0056] By setting the end 101 as the end that enters the human rectum, the rectal lumen wraps around the end 101. When the patient contracts the rectal muscle group, it squeezes the first balloon 202. Based on the air pressure balance characteristics, the second balloon 210 expands. A strain gauge layer 211 is wrapped and laid on the outside of the second balloon 210, which drives the sensitive grid 2113 to deform and squeeze the piezoelectric element 209. The change in the output voltage of the connected bridge is measured, thereby determining the pressure change on the strain gauge layer 211, which facilitates the assessment of muscle strength effect.

[0057] By installing electrode pads 212 on the end 101, and using the connector 7 and cable to connect to the electromyography (EMG) detector 8, EMG and muscle strength data can be collected. At this time, the end 101 and the soft silicone plug 401 are wrapped around the rectal lumen, which can adapt to the rectal lumen structure and effectively reduce the foreign body sensation. The soft silicone plug 401 and the threaded ring 402 are adapted to the rectal lumen structure, avoiding the problem of inaccurate measurement data caused by the detection rod 1 falling off during measurement.
