Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically to an external device for treating male erectile dysfunction. Background Technology

[0002] With rapid socio-economic development, many men are experiencing health problems due to factors such as overnutrition, reduced physical labor, sedentary lifestyles, and increased work pressure. Erectile dysfunction (ED) is often the first sign of a men's health crisis. Depression, anxiety, strained interpersonal relationships, smoking, excessive alcohol consumption, overwork, and immense stress can all contribute to ED. ED refers to the persistent or recurrent inability of a man to achieve or maintain an erection sufficient for sexual intercourse. This can manifest as inconsistent erectile function, a tendency to maintain only a brief erection, or complete inability to achieve an erection. Experts point out that this is a common health problem for men over 40. It is estimated that more than half of men over 40 suffer from ED to varying degrees, totaling 152 million men worldwide. ED can cause depression, low self-esteem, and low mood in men, becoming a factor affecting family happiness and well-being.

[0003] Vacuum erection devices (VEDs), as a non-invasive, non-pharmacological physical treatment, have been recommended by clinical guidelines as a second-line treatment option for erectile dysfunction (ED). Their basic principle is to increase blood flow to the corpora cavernosa through negative pressure suction, causing passive penile engorgement and erection, while a constricting ring blocks venous return to maintain the erection.

[0004] Chinese Patent Publication No. CN114504479B discloses an external device for treating male erectile dysfunction, comprising a housing, an inner upper surface of which communicates with the outside, a treatment sleeve fixedly fixed through the lower inner surface of the housing, a metal diaphragm fixedly installed inside the housing, an electromagnetic coil sleeved on the outer surface of the metal diaphragm and fitted against the inner wall of the electromagnetic coil, a circular plate fixedly connected to the upper part of the housing, an inner cavity formed between the outer surface of the treatment sleeve, the inner wall of the housing, and the bottom of the circular plate, with the metal diaphragm and the electromagnetic coil both located inside the inner cavity, and mounting grooves formed on the left and right side walls of the upper part of the housing. This device treats male erectile dysfunction through external shock waves, resulting in good therapeutic effect. Furthermore, the device is convenient to use and suitable for different individuals, making it highly practical.

[0005] However, existing external devices for treating erectile dysfunction, such as those described above, still have the following technical limitations: (1) Single negative pressure control method: Existing manual devices rely on manual suction, and users cannot know the real-time negative pressure value. They can only control it by feeling, which can easily lead to excessive negative pressure causing tissue damage (subcutaneous bruising, edema, pain) or insufficient negative pressure affecting the erection effect. While automatic devices have pressure control function, the pressure program is fixed and cannot be flexibly adjusted according to individual differences and real-time feelings during use. In addition, automatic pumps have complex structures, high costs, and poor portability.

[0006] (2) The sealing structure is rigid and cannot adapt to changes in the erection angle: Traditional devices use a rigid sealing ring or a fixed-angle sealing flange at the contact point between the base of the cylinder and the penis. After the penis becomes erect under negative pressure, it will naturally rise forward and upward (the normal erection angle is about 60°~90° with the abdominal wall). However, the vacuum cylinder axis of the existing device is fixed, which causes the erect penis to exert lateral pressure on the cylinder wall. On the one hand, this causes local pressure concentration and pain, and on the other hand, it damages the seal and causes air leakage, reducing the negative pressure maintenance effect.

[0007] (3) Single treatment modality: Existing devices rely solely on negative pressure mechanical action and lack auxiliary physical stimulation to promote vasodilation, improve tissue metabolism, and enhance the compliance of the corpus cavernosum, thus limiting the potential for improving treatment efficacy.

[0008] (4) Lack of temperature management: During the negative pressure suction process, due to the air flow inside the tube and the compression of local blood vessels, the surface temperature of the penis usually drops by 1~2℃. Patients feel cold and uncomfortable. Low temperature also causes vasoconstriction, which is not conducive to blood perfusion and erection maintenance. Summary of the Invention

[0009] The purpose of this invention is to provide an external device for treating male erectile dysfunction, overcoming the limitations of existing devices in that they have a single negative pressure control method, manual devices cannot accurately control pressure, causing tissue damage or affecting erectile function, automatic devices have fixed pressure programs, complex structures, high costs, poor portability, and rigid sealing structures that cannot adapt to changes in penile angle after erection, easily causing pressure pain, air leakage, and pressure loss; at the same time, the treatment modality is singular, lacking auxiliary physical stimulation, resulting in limited efficacy; in addition, there is no temperature control design, and local cooling under negative pressure causes physical discomfort, and can also constrict blood vessels, hindering blood perfusion and erection maintenance.

[0010] To achieve the above objectives, the technical solution adopted by the present invention to solve its technical problem is as follows: An external device for treating male erectile dysfunction has been designed.

The locking rod is slidably connected in the arc-shaped groove, and an angle adjustment button for fastening the ball joint seat is connected to the outer end of the locking rod.

[0013] Preferably, the upper inner side of the I-shaped connector is provided with a pulse stimulation airway, which is connected to the tail of the inner cylinder, and an inflation channel is provided on the outer side of the pulse stimulation airway, which is connected to the inflation interlayer.

[0014] Preferably, the inner cylinder is made of flexible medical silicone, and its front end is provided with a plurality of vent holes, which are arranged in a ring array on the peripheral wall of the inner cylinder; The inner wall of the inner cylinder has a ring array of several airbags, which are arranged along the length of the inner cylinder and whose lower ends are connected to the pulse stimulation airway.

[0015] Preferably, the temperature control sensor is disposed within the gap between the outer cylinder and the inner cylinder, and the temperature control sensor includes: A flexible heating element is disposed on the inner wall of the front end of the outer cylinder and connected to the control center via a wire, and connected to the control panel disposed on the outer wall of the outer cylinder; The sensor is located inside the rear end of the outer cylinder and is connected to the control center via a sensor signal line, and is also connected to the control panel.

[0016] Preferably, the sensors include a pressure sensor and a temperature sensor, which are respectively connected to the control center, and the control panel is provided with a display screen and control buttons.

[0017] Preferably, the negative pressure pump is equipped with a pressure adjustment button and an on / off button.

[0018] Preferably, the outer cylinder is made of high-transmittance engineering plastic with a hollow structure, and a negative pressure interface connected to the output end of the negative pressure pump is provided at its front end. A scale is provided on the outer peripheral wall of the outer cylinder along its length.

[0019] The beneficial effects of this invention are: 1. This invention adopts a ball joint seat and a ball joint head spherically movable connection structure. The outer cylinder can be flexibly deflected to adjust the fitting angle, and the angle can be locked by the angle adjustment button to adapt to different user body shapes and usage postures. The rear end of the ball joint seat is equipped with a silicone sealing ring, which can adapt to deformation with the change of angle, always keep the contact surface tightly sealed, effectively avoid the problems of local pressure and negative pressure leakage caused by improper angle, and ensure a stable and reliable negative pressure working environment.

[0020] 2. The outer cylinder of this invention is made of high-transmittance engineering plastic material, which combines structural strength and light transmission for observation.

[0021] 3. In this invention, a trumpet-shaped silicone protective ring is provided at the rear end of the inner cylinder, which has a good fit and wrapping effect, and the inner sealing ring further improves the overall airtightness; by controlling the center to inflate the air-filled interlayer in a quantitative manner, the locking ring is driven to slide precisely to the root of the penis, physically compressing and blocking the venous blood return, while not affecting the normal blood supply of the arteries, thus maintaining the erection state stably in a mechanically controllable manner.

[0022] 4. The present invention features axially distributed airbags arranged in a ring array on the inner wall of the inner cylinder. Combined with pulse stimulation of the airway, the airbags are periodically inflated and deflated, creating a biomimetic massage effect of circumferential compression and relaxation on the penile body at a specific frequency. This effectively promotes penile blood return and reperfusion, enhances the physiological function of the corpus cavernosum pump, and assists in improving erectile function from a physical therapy perspective, thereby improving the long-term treatment and rehabilitation effect.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this invention.

[0030] like Figure 1-15 As shown, the present invention provides an external device for treating male erectile dysfunction, including an outer cylinder 1, a negative pressure pump 2 disposed at the front end of the outer cylinder 1, and an inner cylinder 5 inside. The outer cylinder 1 is made of a hollow structure of high light transmittance engineering plastic, preferably polycarbonate (PC) material, and a negative pressure interface connected to the output end of the negative pressure pump 2 is provided at its front end. A scale 14 is provided on the outer peripheral wall of the outer cylinder 1 along its length direction for observing changes in penile erection length.

[0031] It also includes a ball joint seat 3, which is movably connected to the rear end of the outer cylinder 1. When the penis first becomes erect, the outer cylinder 1 can rotate flexibly around the ball joint seat 3 as a fulcrum to adjust to the most suitable fitting angle. This not only facilitates the continuous performance of subsequent treatment operations but also effectively avoids air leakage problems caused by local pressure or poor sealing due to improper angle. In addition, a silicone sealing ring 31 is provided at the rear opening of the ball joint seat 3. Even if the angle of the outer cylinder 1 changes due to treatment needs, the silicone sealing ring 31 can adapt to deformation and always maintain a tight sealing fit with the contact surface, ensuring a stable negative pressure environment.

[0032] The control center 4 is installed at the front end inside the outer cylinder 1 and connected to the output end of the negative pressure pump 2. As the core control unit of the entire device, it is responsible for coordinating and commanding the operation of all functions. The control center 4 is also connected to a temperature control sensor, which is installed on the I-shaped connector 8 at the rear end of the inner cylinder 5. This sensor can monitor the temperature and pressure changes in the treatment area in real time and accurately. By feeding back this data, relevant parameters can be adjusted to achieve dynamic management and precise control of temperature and pressure, thereby ensuring the effectiveness of treatment while maximizing safety and comfort during use.

[0033] In the above scheme, the rear end of the inner cylinder 5 is connected to a silicone protective ring 9 via an I-shaped connecting seat 8. The silicone protective ring 9 has a trumpet-shaped structure that is smaller at the front and larger at the back to ensure better fit and wrapping of the target area. A sealing ring 91 is provided on its inner side to effectively enhance the overall airtightness. An inflatable interlayer 93 is provided inside the silicone protective ring 9. The inflatable interlayer 93 is annularly arranged inside the silicone protective ring 9. The inflatable interlayer 93 is connected to the I-shaped connecting seat 8 and is connected to the control center 4 via a control air pipe 41 to achieve remote or automatic gas control. A movable locking ring 92 is sleeved on the outside of the inflatable interlayer 93. It can be removed from the silicone protective ring 9 by the expansion of the inflatable interlayer 93 to block venous return and maintain penile erection.

[0034] Specifically, a fixed amount of gas is injected into the inflatable interlayer 93 via the control center 4, causing the inflatable interlayer 93 to expand uniformly. The radial pressure generated by the expansion pushes the locking ring 92 outward, causing it to move forward along the outer surface of the silicone protective ring 9, and finally be precisely pushed and stably stationed at the base of the penis. This achieves physical compression of the veins at the base of the penis, effectively blocking venous blood return while ensuring that arterial blood supply is basically unaffected, thus providing reliable and adjustable mechanical support for maintaining the necessary erection.

[0035] In the above scheme, a ball joint head 12 is connected to the outer side of the I-shaped connecting seat 8. The ball joint head 12 is located at the rear end of the outer cylinder 1 and is spherically connected to the ball joint seat 3. That is, the ball joint head 12 is assembled and movably connected to the internal cavity of the ball joint seat 3 through its spherical structure, which allows the outer cylinder 1 to deflect within the connecting seat 3 as needed. An arc-shaped sliding groove 32 is provided on the side wall of the ball joint seat 3. A locking rod is connected to the outer wall of the ball joint head 12. The locking rod is slidably connected within the arc-shaped sliding groove 32 and can slide along the trajectory of the arc-shaped sliding groove 32. An angle adjustment button 13 for fastening the ball joint seat 3 is connected to the outer end of the locking rod. By loosening or tightening the angle adjustment button 13, the ball joint seat 3 can be loosened or locked, allowing it to rotate as needed or locked at the currently adjusted angle position.

[0036] In the above scheme, a pulse stimulation airway 83 is provided on the upper inner side of the I-shaped connecting seat 8. The pulse stimulation airway 83 has an annular cavity structure and is connected to the tail of the inner cylinder 5, forming a key path for airflow circulation. An inflation channel 82 is provided on the outer side of the pulse stimulation airway 83, which is connected to the inflation interlayer 93, thus facilitating the inflation and deflation of the inflation interlayer 93. To achieve precise airflow control, a first connecting pipe 81 and a second connecting pipe 84 are respectively connected to the top of the pulse stimulation airway 83 and the inflation channel 82. The first connecting pipe 81 and the second connecting pipe 84 are respectively connected to the control center 4 through two control air pipes 41. The entire workflow is uniformly controlled by the control center 4, which can accurately deliver or discharge gas to the first connecting pipe 81 and the second connecting pipe 84 through the two control air pipes 41, thereby controlling the inflation and deflation of the pulse stimulation airway 83 and the inflation interlayer 93 respectively.

[0037] In the above scheme, the inner cylinder 5 is coaxially disposed inside the outer cylinder 1. The inner cylinder 5 is made of flexible medical silicone, and its front end has several ventilation holes 51. The ventilation holes 51 are arranged in a ring array on the circumferential wall of the inner cylinder 5, mainly used to receive and conduct negative pressure airflow, gently inducing arterial blood to flow into the corpora cavernosa to achieve initial erection. Several air bladders 52 are arranged in a ring array on the inner wall of the inner cylinder 5. The air bladders 52 are evenly arranged along the axial length of the inner cylinder 5. The lower end of the air bladder 52 is provided with a connecting port, which is used to connect with the pulse stimulation airway 83. In conjunction with the pulse stimulation airway, periodic inflation and deflation are achieved, forming a biomimetic massage effect of circumferential compression and relaxation on the penile body at a specific frequency. This effectively promotes penile blood return and reperfusion, enhances the physiological function of the corpora cavernosa pump, and assists in improving erectile function from a physical therapy perspective.

[0038] Specifically, during pulse stimulation therapy, the trachea 41 is controlled to periodically inflate and deflate the pulse stimulation airway 83 at a specific frequency, that is, to periodically inflate and deflate the airbag 52 inside the inner cylinder 5 at a specific frequency. The airbag 52 generates gentle circumferential compression and relaxation on the penile body, simulating a mechanical stimulation similar to "massage", promoting blood return and reperfusion, and enhancing the function of the corpus cavernosum pump.

[0039] In the above scheme, the temperature control sensor is installed in the gap between the outer cylinder 1 and the inner cylinder 5 to monitor and control the temperature and pressure in this area in real time and accurately. The temperature control sensor includes a flexible heating element 6, which is installed on the inner wall of the front end of the outer cylinder 1 and connected to the control center 4 via a wire 61. It is also connected to the control panel 11 installed on the outer wall of the outer cylinder 1, allowing for manual setting and fine adjustment of the temperature via the panel, and also facilitating the operator to visually view the current heating status. The sensor 7 is installed at the rear end inside the outer cylinder 1 and connected to the control center 4 via a sensing signal line 71, and is also connected to the control panel 11. This ensures that the system can continuously monitor the temperature and pressure in the gap in real time, and all status information can be clearly read through the panel, facilitating timely understanding of the operating status.

[0040] Sensor 7 includes a pressure sensor and a temperature sensor for real-time monitoring of the working environment, both of which are reliably electrically connected to the control center 4. The control panel 11's interface clearly distinguishes and arranges two main functional areas: a display screen for dynamically displaying monitoring data and system status, and control buttons for operators to input commands and adjust parameters.

[0041] In the above scheme, the negative pressure pump 2 is equipped with a pressure adjustment button 21 and an on / off button 22 to enable the negative pressure pump 2 to start and effectively control the negative pressure state, thus balancing ease of operation and accuracy of function. The on / off button 22 controls the start and stop of the pump body, ensuring that it can enter the working state according to the instructions; while the pressure adjustment button 21 allows the operator to flexibly and accurately set and adjust the specific level of negative pressure according to actual needs, thereby achieving dynamic and effective control of the negative pressure state.

[0042] Specific implementation examples: The specific operating procedure for using this external device for treating erectile dysfunction in men includes the following steps: (1) Angle adaptation First, the angle of the outer cylinder 1 is adjusted through the spherical connection structure between the ball joint seat 3 and the ball joint head 12. The outer cylinder 1 can rotate flexibly with the ball joint seat 3 as the fulcrum. After the locking rod slides along the arc-shaped groove 32 on the side wall of the ball joint seat 3 to the appropriate position, the angle adjustment button 13 is tightened to lock the angle. The silicone sealing ring 31 at the rear end of the ball joint seat 3 adapts to deformation to ensure that the outer cylinder 1 and the contact surface are sealed and fitted, thus establishing a sealing foundation for the subsequent negative pressure environment.

[0043] (2) Negative pressure induction The pump body is started by the start / stop button 22 of the negative pressure pump 2, and a suitable negative pressure value is set by the pressure adjustment button 21. The negative pressure pump 2 draws air into the gap between the outer cylinder 1 and the inner cylinder 5 through the negative pressure port at the front end of the outer cylinder 1 to form a stable negative pressure environment.

[0044] Negative pressure is applied to the penis through the vents 51 of the annular array at the front end of the inner cylinder 5, inducing arterial blood to flow into the corpora cavernosa, thus achieving initial erection. The scale 14 on the outer side of the outer cylinder 1 can be used to observe changes in the length of the erect penis in real time.

[0045] (3) Mechanical assistance The control center 4 injects a fixed amount of gas into the inflatable interlayer 93 of the silicone protective ring 9 through the control trachea 41, so that the inflatable interlayer 93 expands evenly. The radial pressure of the expansion pushes the outer locking ring 92 forward along the silicone protective ring 9, and finally locks it at the root of the penis, physically compressing the veins to block venous return, while ensuring normal arterial blood supply, thereby stabilizing and maintaining the erect state of the penis.

[0046] The horn-shaped structure of the silicone protective ring 9 and the inner sealing ring 91 further enhance the airtightness and prevent negative pressure leakage; the silicone protective ring 9 is connected to the rear end of the inner cylinder 5 through the I-shaped connecting seat 8 to ensure structural stability.

[0047] (4) Pulse stimulation The control center 4 controls the trachea 41 to periodically inflate and deflate the pulse stimulation airway 83 of the I-shaped connector 8. The airflow enters the airbag 52 through the connecting port at the lower end of the airbag 52 on the inner wall of the inner cylinder 5, causing several airbags 52, which are evenly distributed along the axis of the inner cylinder 5 and arranged in a ring, to periodically inflate and contract at a specific frequency. This produces a gentle circumferential compression and relaxation on the penile body, simulating a massage effect, promoting penile blood return and reperfusion, enhancing the function of the corpus cavernosum pump, and assisting in improving the treatment effect.

[0048] (5) Monitoring and regulation A temperature control sensor monitors the device's operating status in real time. This device is located in the gap between the outer cylinder 1 and the inner cylinder 5 and is mounted on the I-shaped connector 8. A flexible heating element 6 is located on the inner wall of the front end of the outer cylinder 1 and is connected to the control center 4 via a wire 61. It is also connected to the control panel 11 on the outside of the outer cylinder 1. The temperature can be manually set and adjusted via the control panel 11 to provide a suitable temperature environment for the treatment area.

[0049] Sensor 7 is located inside the rear end of the outer cylinder 1 and is connected to the control center 4 and control panel 11 via a sensor signal line 71. Sensor 7 includes a pressure sensor and a temperature sensor, continuously collecting pressure and temperature data within the gap and feeding it back to the control center 4. The control center 4 dynamically adjusts parameters such as negative pressure, temperature, inflation volume, and pulse frequency based on the feedback data to ensure treatment effectiveness while improving safety and comfort. The display screen of the control panel 11 can display monitoring data and system status in real time, and the control buttons are used to input operation commands.

[0050] It should be noted that the control center 4, as the core unit, is installed inside the front end of the outer cylinder 1 and is connected to the output end of the negative pressure pump 2. It coordinates the operation of the negative pressure pump 2, the temperature control sensor, the air-filled interlayer 93, and the pulse stimulation airway 83. Operators can flexibly adjust various parameters through the control panel 11, the pressure adjustment button 21 of the negative pressure pump 2, and the on / off button 22 to achieve automated and precise control of the entire treatment process.

[0051] The above specific embodiments further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above are merely specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
