Description

Technical Field

[0001] The invention relates to the technical field of rehabilitation training equipment, in particular to an anal contraction training device. Background Art

[0002] The anal sphincter is an important group of smooth muscles in the rectal area of ​​the human body. Its function is essential for maintaining normal bowel control. Due to various reasons (such as surgery, trauma or aging), the anal sphincter may be damaged or its function may decline, leading to problems such as loss of bowel control and incontinence. Therefore, training to restore the function of the anal sphincter has become an important means of treatment.

[0003] At present, common training methods include training the contraction of the sphincter by inserting an elastomer. Elastomer insertion usually uses soft elastic materials (such as silicone) to physically stimulate the anal sphincter to contract, thereby helping patients restore the function of the sphincter. The principle of this method is to use the rebound force of the elastomer to promote muscle contraction and train the elasticity and strength of the anal sphincter. Although this training method can achieve functional recovery of the anal sphincter to a certain extent, it also has some significant defects. First, it is prone to the problem of insufficient elastic support. During the training process, as the sphincter gradually recovers and the elastic rebound decays, it may not be able to provide sufficient support, resulting in a weakened training effect, and unable to maintain sufficient antagonistic training intensity, affecting the treatment effect; second, the current training equipment is usually unable to evaluate the patient's sphincter contraction degree in real time, making it difficult for patients to determine whether the training is effective, and it is easy to have insufficient training. There is a lack of real-time feedback on the contraction intensity, which makes it difficult to accurately control the treatment effect and scientifically guide the recovery process.

[0004] Therefore, the existing technology has certain limitations in anal sphincter function recovery training, and there is an urgent need for a training device with more lasting elastic resistance and improved contraction training degree to improve the effectiveness of anal sphincter recovery training. Summary of the invention

[0005] The purpose of the present invention is to address the problems existing in the above-mentioned background technology and to propose an anal contraction trainer, which is an implant body composed of a flexible main body and an elastic member that provides an anti-elastic force. The implant is inserted into the anus to perform sphincter contraction training, thereby providing more lasting training effectiveness and better recovery effect. In addition, a specially designed detection device is used to provide feedback on whether the sphincter contraction is in place during training, thereby evaluating the training degree and promoting the patient's training to be in place.

[0006] In order to achieve the above-mentioned object of the invention, the present invention adopts the following technical solutions: An anal contraction trainer includes a trainer body, the trainer body includes an insertion body for insertion through the anus, the insertion body includes an outer covering portion, a shape maintaining portion and a contraction resistant portion, the shape maintaining portion uses a flexible material to maintain the overall shape of the insertion body, the outer covering portion uses a flexible non-water-permeable material and covers the shape maintaining portion, the contraction resistant portion includes an elastic member, the elastic member is fixed inside the shape maintaining portion or embedded in the shape maintaining portion, and the elastic member provides a reverse resistant force when the insertion body contracts.

[0007] By using a combined design of an outer covering portion, a shape maintaining portion and a contraction resistant portion, the shape of the implant can be effectively maintained, and an additional elastic member is used to provide the required elastic resistant force, which can provide a lasting reverse supporting force during contraction, thereby helping to enhance the training effect of the anal sphincter.

[0008] Preferably, the implant is in the form of a columnar structure with a narrowed middle portion, the shape maintaining portion is hollow inside to form an inner cavity, the elastic member is configured as at least one radial force spring, the spring line path of the radial force spring extends in a wave shape or a broken line shape and surrounds an axis until the ends are connected to form a cylindrical ring structure, the radial force spring is coaxial with the inner cavity, and the radial force spring maintains the shape of the inner cavity when the implant is not subjected to external force. The radial force spring provides additional support for the shape maintaining portion, and provides a reverse antagonistic force when the implant is subjected to lateral compression, so that the implant can maintain its shape when subjected to a smaller external force range, and is convenient for insertion into the anus; when subjected to lateral compression, it can provide a relatively uniform reverse antagonistic force, adapt to the sphincter contraction mode, and enhance the feedback force during training.

[0009] Preferably, a plurality of linings are fixedly arranged outside the spring wire of the radial force spring, and the plurality of linings are evenly distributed around the axis of the radial force spring, and the outer side of the linings is attached to the inner wall of the shape maintaining portion, and one lining does not cover two adjacent spring wires at the same time. The arrangement of the linings can ensure the stability of the radial force spring and evenly distribute the transmission of force, while preventing the thinner spring wire from exerting a large pressure on the implanted body, and preventing the patient from having a sense of discomfort during training and reducing comfort.

[0010] Preferably, a handheld controller is further included, wherein the handheld controller is provided with a prompt module and a corresponding control circuit, wherein the prompt module adopts one of sound, light and vibration or a combination of two or three of the modes; the implanted body also includes a detection core for detecting the degree of contraction of the sphincter training, wherein the detection core includes a trigger module and a circuit module, and the circuit module of the detection core is connected to the control circuit of the handheld controller by wire or wirelessly, and when the contraction degree of the implanted body reaches the trigger condition of the trigger module, the handheld controller receives the signal of the detection core and generates a prompt action.

[0011] The combination of the handheld controller and the prompt module provides real-time feedback on the training process. Users can clearly know the training progress and whether the contraction requirements have been met through prompts such as sound, light, and vibration, thereby avoiding training errors or over-training and improving the accuracy of training effects.

[0013] The design of the trigger module can monitor the contraction status in real time and generate feedback when the conditions are met. The working principle of the sealed air bag and elastic diaphragm ensures that the prompt signal is triggered under specific contraction conditions, further enhancing the device's feedback and control of the anal sphincter training intensity, thereby improving the targetedness and effectiveness of the training.

[0014] Preferably, the seat body is provided with an air charging and discharging interface, which is a normally closed air charging and discharging interface connected to a sealed air bag, and an external air pump device can be connected to the air charging and discharging interface to control the air pressure of the sealed air bag.

[0016] Preferably, a flexible film pressure sensor is provided between the outer covering part and the shape maintaining part.
