Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a postoperative muscle recovery pressurization training cuff. Background Art

[0002] Blood Flow Restriction Training (BFRT) is an innovative physical training method. Its core lies in the use of specially designed pressure devices to implement precise external pressure on the proximal upper and / or lower limbs during training, thereby partially restricting arterial blood flow and simulating the effects of high-intensity training at a lower exercise intensity or neuromuscular electrical stimulation.

[0003] In the field of rehabilitation medicine, BFRT has been proven to be an effective means of preventing and treating various types of muscle disuse atrophy, especially for people who are recovering from surgery, bedridden for a long time, have their limbs fixed, or are at risk of muscle disuse atrophy due to aging. By combining low-intensity exercise or neuromuscular electrical stimulation, BFRT can effectively promote the maintenance and recovery of muscle mass without adding too much physical burden, accelerate the recovery process of injuries, and play a positive role in the overall health and development of the musculoskeletal system. In addition, the application of BFRT is also of great significance for patients with chronic diseases. It can not only improve vascular function, reduce vascular stiffness, and enhance venous compliance, thereby promoting cardiovascular health, but also promote microangiogenesis, reduce blood pressure after exercise, and improve the ability to carry out daily activities, bringing positive changes to their quality of life.

[0004] However, the current BFRT cuff design on the market has obvious shortcomings, which limits its effect and experience in practical applications. Specifically, there are the following defects:

[0005] 1. The rectangular cuff is difficult to fit the natural tapered contour of the human limbs, resulting in uneven pressure distribution, increasing the wearer's discomfort and pain, and affecting hemostasis and training effects.

[0006] 2. The inflation port is improperly designed and can be easily touched by mistake during rehabilitation training, causing the cuff to shift in position and affecting training stability.

[0007] 3. The cuff has the same width over the entire length and lacks auxiliary design for tying. It is impossible to hold down the lower cuff when tying the cuff, which results in the cuff being tied loosely and easily loosens.

[0008] 4. Existing cuffs generally lack pressure monitoring function and cannot provide real-time feedback and adjust to the optimal training pressure, which limits the implementation of personalized training programs.

[0009] Therefore, we propose a postoperative muscle recovery compression training cuff to solve the above technical problems. Summary of the invention

[0010] In order to solve at least one technical problem existing in the above-mentioned prior art, the present invention provides a postoperative muscle recovery pressurization training cuff.

[0011] The technical solution adopted by the present invention is as follows:

[0012] A postoperative muscle recovery pressurized training cuff comprises a cuff body, the cuff body is designed in an arc shape, the inner side and outer side of the two ends of the cuff body are respectively provided with matching Velcro sub-surfaces and Velcro main surfaces, an airbag and a pressure sensor are provided on the inner side of the cuff body, an inflation port is provided on the airbag, the inflation port passes through the cuff body and extends to the outside of the cuff body, and the inflation port is oriented perpendicular to the cuff body.

[0013] In a further technical solution, the widths of the two ends of the cuff body are different, the Velcro sub-surface is arranged on the inner side of the narrow end of the cuff body, and the Velcro mother surface is arranged on the outer side of the wide end of the cuff body.

[0014] In a further technical solution, straps are provided on both upper and lower sides of the narrow end of the cuff body, and Velcro sub-surfaces are provided on both straps.

[0015] In a further technical solution, a deflation button is provided on the inflation port to enable emergency deflation of the airbag.

[0016] In a further technical solution, the pressure sensor and the airbag are respectively located on the upper and lower sides of the inner side of the cuff body. When the cuff body is tied to a limb, the pressure sensor can directly contact the limb and be located on the distal end of the limb.

[0017] In a further technical solution, an inflation tube is sealedly connected to the inflation port.

[0018] In a further technical solution, the cuff body is made of soft and breathable medical-grade elastic material.

[0019] In a further technical solution, the inner surface of the cuff body is also covered with an antibacterial and anti-allergic layer, and the antibacterial and anti-allergic layer is made of nano silver ion antibacterial material.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0021] Fit and comfort: The cuff body of this training cuff adopts an arc design. When it is wrapped and fixed on the limb, it can naturally form a cone shape, closely fitting the natural cone contour of the human limb. This design not only solves the problem of uneven pressure distribution caused by loose fit of traditional rectangular cuffs, but also improves the comfort of the wearer, reduces discomfort and pain, and ensures good hemostasis and training effects during training.

[0022] Safety: The inflation port of the airbag is set on the outside of the cuff body and perpendicular to the cuff body. This layout effectively avoids the risk of accidental touch during rehabilitation training, prevents interference with the wearer's training or displacement of the cuff body, ensures the continuity and stability of training, and provides a safer training environment for the wearer.

[0023] Personalized training: The pressure sensor monitors the pressure of the airbag on the limbs in real time, which not only ensures the safety of the training process and ensures that the pressure is always within a safe and effective range, but also allows the wearer or rehabilitation therapist to flexibly adjust the training plan according to the pressure data to achieve personalized training and further improve the training effect and recovery speed.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 4The present invention provides a postoperative muscle recovery pressurized training cuff, including a cuff body 1, the cuff body 1 is designed in an arc shape, and the inner and outer sides of the two ends of the cuff body 1 are respectively provided with matching Velcro sub-surfaces 8 and Velcro mother surfaces 9, an air bag 2 and a pressure sensor 3 are provided on the inner side of the cuff body 1, and an inflation port 4 is provided on the air bag 2, the inflation port 4 penetrates the cuff body 1 and extends to the outside of the cuff body 1, and the inflation port 4 is perpendicular to the cuff body 1.

[0032] This training cuff is well suited for blood flow restriction training. It can apply precise external pressure to the limbs during training. By partially restricting arterial blood flow, it can effectively simulate the effects of high-intensity training under conditions of lower exercise intensity or neuromuscular electrical stimulation, thereby effectively promoting the maintenance and recovery of muscle mass, accelerating the recovery process of injuries, and playing a positive role in the overall health and development of the musculoskeletal system. The specific usage is as follows:

[0033] First, by aligning one side of the airbag 2 with the part that needs to be pressurized, and then using the Velcro sub-surface 8 and Velcro main surface 9 on both sides of the cuff body 1 to stably and comfortably fix the cuff body 1 on the limb that needs to be trained. Next, connect the inflation port 4 through the inflation device, inflate the airbag 2 through the inflation port 4, and observe the reading of the pressure sensor 3 at the same time to ensure that the pressure of the cuff on the limb is within a safe and effective range, so as to complete the wearing of the training cuff and perform blood flow restriction training. In addition, when the wearer's limb is inflated and squeezed to stop bleeding, the pressure sensor 3 can be used to detect the pulse of the limb. As the squeezing force of the airbag 2 on the limb continues to increase, when the pressure sensor 3 cannot detect the pulse of the limb, the pressure of the airbag 2 at this time is the wearer's minimum hemostatic pressure, achieving the function of measuring the wearer's minimum hemostatic pressure.

[0034] Compared with the traditional rectangular cuff, the training cuff designed above has the following advantages:

[0035] Fit and comfort: The cuff body 1 of the training cuff adopts an arc design. When it is wrapped and fixed on the limb, it can naturally form a cone shape and closely fit the natural cone contour of the human limb. This design not only solves the problem of uneven pressure distribution caused by loose fit of traditional rectangular cuffs, but also improves the comfort of the wearer, reduces discomfort and pain, and ensures good hemostasis and training effects during training.

[0036] Safety: The inflation port 4 of the airbag 2 is arranged on the outside of the cuff body 1 and is arranged perpendicular to the cuff body 1. This layout effectively avoids the risk of accidental touch during rehabilitation training, prevents interference with the wearer's training or displacement of the cuff body 1, ensures the continuity and stability of training, and provides a safer training environment for the wearer.

[0037] Personalized training: The pressure value of the airbag 2 on the limbs is monitored in real time by the pressure sensor 3, which not only ensures the safety during the training process and ensures that the pressure is always within a safe and effective range, but also allows the wearer or the rehabilitation therapist to flexibly adjust the training plan according to the pressure data, realize personalized training, and further improve the training effect and rehabilitation speed.

[0038] In a specific embodiment, see Figure 2 and Figure 3 The widths of the two ends of the cuff body 1 are different, the Velcro sub-surface 8 is arranged on the inner side of the narrow end of the cuff body 1, and the Velcro mother surface 9 is arranged on the outer side of the wide end of the cuff body 1.

[0039] By setting the widths of the two ends of the cuff body 1 to be different, the stability and firmness of wearing can be enhanced. Specifically, when wearing a training cuff, one hand firmly presses the wide end of the cuff body 1, and the other hand pulls the narrow end of the cuff body 1 and wraps it along the wearer's limbs, and finally fits the Velcro sub-surface 8 of the narrow end to the Velcro parent surface 9 of the wide end. Since the width of the narrow end is smaller, it will not hinder the wide end from firmly pressing down on the limbs when wrapping, thereby ensuring the fit and tightness of the cuff body 1, reducing the probability of the cuff body 1 loosening, and bringing a more comfortable and safe training experience to the wearer.

[0040] In a specific embodiment, see Figure 2 The upper and lower sides of the narrow end of the cuff body 1 are both provided with straps 5, and the two straps 5 are both provided with Velcro sub-surfaces 8.

[0041] By providing two straps 5 at the narrow end of the cuff body 1 and arranging the Velcro sub-surface 8 on the straps 5, after the cuff body 1 is wrapped and worn, the space reserved between the two straps 5 allows the inflation port 4 of the airbag 2 to be exposed, which is beneficial for inflation and deflation operations.

[0042] In a specific embodiment, see Figure 4 The inflation port 4 is provided with a deflation button 6, which can make the airbag 2 deflate urgently.

[0043] In an emergency, such as when the wearer feels uncomfortable or needs to stop training immediately, the gas in the airbag 2 can be quickly released by pressing the deflation button 6, so that the cuff can be quickly relaxed, thereby avoiding continuous pressure or injury to the limbs and improving the safety of training.

[0044] In a specific embodiment, see Figure 2The pressure sensor 3 and the airbag 2 are respectively located on the upper and lower sides of the inner side of the cuff body 1. When the cuff body 1 is tied to the limb, the pressure sensor 3 can directly contact the limb and be located on the distal end side of the limb.

[0045] Since the pulse wave is transmitted through the vibration of the arterial blood vessel wall, the pressure sensor 3 directly contacts the limbs, which can reduce the attenuation and interference in the transmission process and more accurately sense the pulse beating. The pulse waveform of the artery is relatively more stable and obvious at a location far away from the heart. Setting the pressure sensor 3 on the distal end of the limb can more easily capture a clear pulse waveform. Therefore, through the above design, the detection accuracy of the pressure sensor 3 can be improved, providing continuous and reliable data support for medical diagnosis, exercise effect evaluation, etc.

[0046] In a specific embodiment, see Figure 4 The inflation port 4 is sealed with an inflation tube 7 .

[0047] The inflation port 4 of the airbag 2 is extended by the inflation tube 7, so as to facilitate the docking with the inflation device, improve the convenience of inflation, and facilitate use.

[0048] In a specific embodiment, the cuff body 1 is made of a soft and breathable medical-grade elastic material.

[0049] The cuff body 1 made of a soft and breathable medical-grade elastic material can fit the wearer's limbs closely. Specifically, the selection of medical-grade elastic materials is not limited to thermoplastic elastomers, polyurethane elastomers and silicone. By making the material breathable, it helps to reduce the stuffiness caused by long-term wearing, providing a more comfortable wearing experience for the wearer.

[0050] In a specific embodiment, the inner surface of the cuff body 1 is also covered with an antibacterial and anti-allergic layer, and the antibacterial and anti-allergic layer is made of nano silver ion antibacterial material.

[0051] By covering the inner surface of the cuff body 1 with an antibacterial and anti-allergic layer made of nano silver ion antibacterial material, it can effectively inhibit and kill a variety of bacteria, fungi and other microorganisms, reduce the risk of infection caused by bacterial contamination, and ensure the safety and reliability of the training cuff during training.

[0052] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
