Description

Technical Field

[0001] The present invention relates to the technical field of medical care, and particularly to a pressure detection device for evaluating the muscle strength of the male pelvic floor muscle. Background Art

[0002] The pelvic floor muscle, that is, the pelvic floor muscle group, refers to the muscle group that closes the pelvic floor. Organs such as the urethra, bladder, vagina, uterus, and rectum of the human body are all located in the pelvic floor muscle group, so as to maintain their normal positions to perform their functions. However, as people age, the pelvic floor muscle gradually ages and relaxes, resulting in the inability of organs to maintain their normal positions, thus causing corresponding functional disorders. Especially in the elderly population, problems such as urinary and fecal incontinence and pelvic organ prolapse are likely to occur after the pelvic floor muscle relaxes. Therefore, it is necessary to train the pelvic floor muscle daily, maintain the contraction intensity of the pelvic floor muscle group, and regularly determine the muscle strength of the pelvic floor muscle through a pelvic floor muscle strength pressure detection device.

[0003] After retrieval, a pressure detection device for evaluating the muscle strength of the female pelvic floor muscle is disclosed in the invention patent with the Chinese patent publication number CN111839554A. The pressure detection device for evaluating the muscle strength of the female pelvic floor muscle in this invention patent outputs gas from the pressure sensing airbag to the air duct through the pressure change of the pressure sensing airbag. The air duct guides the gas from the pressure sensing airbag to the air flow pressure sensor, and the air flow pressure sensor outputs a measurement signal according to the air flow pressure of the gas from the pressure sensing airbag to measure the muscle strength value of the pelvic floor muscle in real time. The pressure detection device of the present invention can accurately measure the initial static pressure muscle strength value of the pelvic floor muscle, the contraction pressure value of the pelvic floor muscle, and the relaxation pressure value of the pelvic floor muscle;

[0004] However, due to the tortuous structure of the human rectum, when this pelvic floor muscle strength pressure detection device is used for detecting the male rectal pelvic floor muscle, it cannot adaptively fill the rectal structure, and it cannot ensure that the detection airbag and the electromyographic element are covered by the rectal skin and in close contact. Therefore, it is easy to cause inaccurate detection data. Thus, a pressure detection device for evaluating the muscle strength of the male pelvic floor muscle is proposed. Summary of the Invention

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-8 , a pressure detection device for evaluating the muscle strength of the male pelvic floor muscle, including a detection rod 1 composed of a head 101 and a rod 102. A testing mechanism 2 is arranged inside the detection rod 1, and a driving mechanism 3 is arranged outside the detection rod 1;

[0030] The testing mechanism 2 includes a support arc plate 201 rotatably connected to the inner side of the head 101. A first balloon 202 is fixedly connected to the inner side of the support arc plate 201. An air delivery catheter 203 is fixedly connected to the first balloon 202 on the side facing the inside of the head 101. A swing rod 204 is hinged to the inner side of the support arc plate 201. A chute seat 205 is fixedly connected to the inside of the head 101. A threaded lead screw 206 is rotatably connected to the inner side of the chute seat 205. A protective layer 207 is coated on the outside of the first balloon 202. A balloon cylinder 208 is fixedly connected to the inside of the rod 102. A piezoelectric sheet 209 is arranged inside 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 inner side of the first balloon 202.

[0031] The driving mechanism 3 includes a mounting groove frame 301 fixed to the outside of the rod 102. A transmission gear 302 is rotatably connected to the side of the mounting groove frame 301 connected to the outside of the rod 102. A gear rotating rod 303 is rotatably connected to the inside of the mounting groove frame 301. A micro motor 304 is fixedly installed on the left side of the mounting groove frame 301.

[0032] Furthermore, one end of the head 101 and the rod 102 connected is fixedly connected with a handle plate. An anti - detachment member 4 is fixed on the top of the handle plate. The anti - detachment member 4 includes a soft silicone plug 401 fixed on the top of the handle plate, and threaded rings 402 are evenly distributed on the outside of the soft silicone plug 401.

[0033] Specifically, the head 101 is placed into the patient's rectal lumen through the handle plate. At this time, the soft silicone plug 401 made of flexible material will fill and adapt to the rectal lumen structure, enabling the rectal lumen to cover the head 101 part. At this time, the threaded rings 402 are used to increase the friction force, avoiding the problem that the detection end cannot adapt to the rectal lumen structure and fall off when the patient contracts the rectal muscle group.

[0034] Further, notches are provided on both the inner left wall and the inner right wall of the end head 101. The number of the supporting arc pieces 201 is two, and they are respectively located inside the two notches. The number of the swing rods 204 and the threaded lead screws 206 is two. Lifting rings are threadedly connected to the outside of the two threaded lead screws 206. One ends of the two swing rods 204 away from the supporting arc pieces 201 are respectively connected to the two lifting rings. The protective layer 207 is a HDPE film layer structure. The number of the piezoelectric sheets 209 is six, and they are evenly distributed in an annular array on the inner side of the bladder cylinder 208.

[0035] Specifically, after the end head 101 is placed into the rectum and wrapped by the rectal lumen, the inner cavity skin will closely adhere to the outside of the first balloon 202. At this time, the protective layer 207 of the HDPE film layer structure maintains the comfort of contacting the skin and improves the wear resistance effect of the first balloon 202.

[0036] The threaded lead screw 206 drives the lifting ring to move up and down, and controls the swing rod 204 to drive the supporting arc piece 201 to change the angle. Based on the piezoelectric effect, the piezoelectric sheet 209 converts the pressure when the second balloon 210 expands into a voltage signal and transmits the voltage signal to the electric bridge, so that the electric bridge loses balance and its output voltage changes.

[0037] Further, the number of the gas delivery conduits 203 is two. One ends of the two gas delivery conduits 203 away from the first balloon 202 are both connected to the top of the second balloon 210 in a penetrating manner. The strain gauge layer 211 includes a base layer 2111 attached to the outside of the second balloon 210. A covering layer 2112 is adhered to the outer layer of the base layer 2111. A sensitive grid 2113 is adhered to the gap between the covering layer 2112 and the base layer 2111.

[0038] Specifically, when the patient contracts the rectal muscle group, the inner cavity skin of the rectum will squeeze the two first balloons 202 on both sides, causing the first balloons 202 to contract and input the gas into the second balloon 210 through the gas delivery conduits 203, thereby driving the second balloon 210 to expand.

[0039] Further, a micro digital display screen 5 is embedded and installed at the bottom of the front surface of the end rod 102. The micro digital display screen 5 is provided with a chip module. The chip module includes an electric bridge and a first amplifier that are electrically connected to each other. The sensitive grid 2113 and the piezoelectric sheet 209 are both connected with leads and are both electrically connected to the electric bridge. The first amplifier is electrically connected to the micro digital display screen 5 through a control circuit.

[0040] Specifically, when the second balloon 210 expands, it drives the strain gauge layer 211 on its outside to deform. When the sensitive grid 2113 deforms, its resistance value will change accordingly. The calculation formula of the resistance change principle 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 changes, and the cross-sectional area A may also change, resulting in a change in the resistance value R.

[0042] Further, the number of electrode pieces 212 is two. Wires 6 are connected to one side of each of the two electrode pieces 212. A second amplifier and an averager that are electrically connected to each other are provided inside the terminal block 207. The wire 6 is electrically connected to the second amplifier. A terminal block 7 is provided on the inner rear wall of the end rod 102. An electromyogram detector 8 is externally connected to the inside of the terminal block 207 through a cable. A lithium battery compartment 9 is fixedly connected to the bottom of the end rod 102. The lithium battery compartment 9 is electrically connected to the micro digital display screen 5.

[0043] Specifically, the sensitive grid 2113 is electrically connected to the bridge through a lead wire. At this time, the sensitive grid 2113 deforms, resulting in a change in resistance, thereby causing the bridge to lose balance, and its output voltage changes. The changed voltage data is amplified and processed by the first amplifier and then received by the chip module of the micro digital display screen 5. The change data of the pressure received by the sensitive grid 2113 is calculated through a logic algorithm and displayed on the screen of the micro digital display screen 5.

[0044] When the inner cavity skin of the rectum wraps the end head 101, the electrode pieces 206 on both sides will contact the inner cavity skin. When the muscle fibers are stimulated by nerve impulses during the contraction of the rectal muscle group by the patient, corresponding potential changes will occur. The electrode pieces 206 capture the potential changes and amplify and process them through the second amplifier, and then the corresponding electrical signals are received by the averager.

[0045] The averager transmits the received electrical signals to the externally connected electromyogram detector 8, which is converted into a visual waveform. By analyzing the waveform graph, the electrical activity pattern of the muscle can be evaluated, including the contraction ability and coordination of the muscle.

[0046] In the micro digital display screen 5, a muscle strength rating standard is set. According to the pelvic floor muscle strength, the pelvic floor muscle strength is graded, which can be used to evaluate the strength and duration of the contraction force of the pelvic floor muscle group. The pelvic floor muscle strength includes:

[0047] 1) Grade 0: In a relaxed state, without contraction.

[0048] 2) Grade 1: In a slightly contracted state, but the muscle strength does not increase significantly.

[0049] 3) Grade 2: In a certain contracted state, the muscle strength increases significantly, but the muscle group is weak.

[0050] 4) Grade 3: In a state of strong contraction, but unable to resist the applied mild pressure.

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

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

[0053] Furthermore, at the bottom of both lead screws 206, a first bevel gear 10 is coaxially fixed. The number of transmission gears 302 is two, and they are respectively located on the left and right sides of the end rod 102. At the opposite ends of the two transmission gears 302, a second bevel gear 11 is coaxially fixed respectively. The two second bevel gears 11 are respectively meshed with the bottoms of the two first bevel gears 10. An active gear meshing with the two transmission gears 302 is arranged outside the gear rotating rod 303. The output shaft of the micro motor 304 is coaxially fixed to the left end of the gear rotating rod 303, and the micro motor 304 is electrically connected to the lithium battery compartment 9.

[0054] Specifically, the micro motor 304 is used to drive the gear rotating rod 303, and the active gears on the gear rotating rod 303 are respectively meshed to drive the two transmission gears 302, so as to control the transmission gears 302 to drive the lead screws 206 to rotate through the first bevel gear 10 and the second bevel gear 11.

[0055] To sum up, for the pressure detection device used to evaluate the muscle strength of the male pelvic floor muscles, the micro motor 304 is used to drive the gear rotating rod 303, the gear rotating rod 303 is meshed to drive the transmission gears 302, the transmission gears 302 are meshed with the first bevel gear 10 through the second bevel gear 11 to control the rotation of the lead screw 206, and the lead screw 206 drives the swing rod 204 to swing at an angle to adjust the fitting degree between the support arc piece 201 and the skin inside the rectum, ensuring that the rectal skin stably wraps the first balloon 202 to improve the accuracy of pressure data detection;

[0056] By setting the end head 101 as the end entering the human rectum, at this time, the inner cavity of the rectum wraps the end head 101, and the patient contracts the rectal muscle group to squeeze the first balloon 202. Based on the air pressure balance characteristic, the second balloon 210 expands. A strain gauge layer 211 is laid outside the second balloon 210, driving the sensitive grid 2113 to deform and cooperate with squeezing the piezoelectric sheet 209 to measure the change in the output voltage of the changed access bridge, so as to determine the change in pressure received by the strain gauge layer 211 and facilitate the evaluation of the muscle strength effect;

[0057] By installing the electrode sheet 206 on the end head 101 and using the terminal block 207 and the cable to externally connect the electromyogram detector 8 to complete the acquisition of electromyogram muscle strength data. At this time, by wrapping the end head 101 and the soft silicone plug 401 with the inner cavity of the rectum, it can adapt to the inner cavity structure of the rectum, effectively reduce the foreign body sensation, and adapt to the inner cavity structure of the rectum through the soft silicone plug 401 and the thread ring 402 made of flexible materials to avoid the problem of inaccurate measurement data caused by the detachment of the detection rod 1 during measurement.
