Description

Technical Field

[0001] This invention relates to the field of anesthesia recovery equipment technology, specifically to a device for rapid recovery of bodily sensation in anesthetized patients after surgery. Background Technology

[0002] In the field of clinical anesthesia, the rapid recovery of postoperative bodily sensation in patients has always been a key concern for medical staff. Traditionally, the recovery of bodily sensation after awakening from anesthesia is often slow and lacks effective active interventions. During natural recovery, patients rely solely on their own bodily functions for regulation, resulting in limited improvement in blood circulation and a passive awakening of neural sensory functions. For example, in cold environments, the vasoconstriction caused by anesthesia is difficult to resolve quickly, leading to poor local blood circulation and further delaying the recovery of sensation in various parts of the body. This can cause patients to experience numbness and limited mobility in their limbs for a prolonged period after surgery. Furthermore, a single stimulation method is insufficient to fully activate the patient's neural sensory system. Sound stimulation alone may not effectively reach deep nerves; simple physical touch such as limb massage lacks precise control over intensity and frequency, making it impossible to dynamically adjust according to different stages of recovery and achieve the desired effect of promoting sensory recovery. Furthermore, traditional methods lack systematic planning for stimulation intensity and patterns, failing to provide appropriate stimulation based on individual patient differences and postoperative recovery progress. This results in prolonged postoperative recovery times and increased time spent in the post-anesthesia care unit (PACU), impacting PACU turnover and causing patients more confusion, anxiety, and discomfort. Therefore, developing a device that effectively promotes rapid recovery of bodily sensation in anesthetized patients is of significant practical importance. Summary of the Invention

The temperature-raising wrapping blanket includes a cotton blanket, three binding straps fixedly connected to the right side surface of the cotton blanket, and several graphene heating wires embedded and fixed in the inner surface of the cotton blanket. The pneumatic touch assembly includes an air tube, several manifolds fixed to the side wall of the air tube, and a straight tube fixed to the end port of the manifold, and multiple silicone airbags arranged in a linear array on the side of the straight tube away from the cotton blanket. The micro vibration motor array comprises multiple micro vibration motors arranged in a rectangular array. The sound stimulation component includes an internally threaded tube fixed to the bottom surface of a cotton blanket, and a Bluetooth speaker screwed onto the internally threaded tube.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the embodiments described below are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. In order to provide a clearer explanation and description of the technical solutions and implementation methods of the present invention, the following describes specific embodiments that implement the preferred technical solutions of the present invention.

[0018] Example 1: This example describes a device for rapid recovery of body sensation after anesthesia, applied to the patient's arm. The core structure is a warming blanket 1-1. The inner surface of the blanket 1-1 has multiple grooves 1-4, with several graphene heating wires 1-3 embedded within these grooves. This provides a warm environment to the patient, promoting blood circulation. Three straps 1-2 are fixedly connected to the right side of the blanket 1-1. The lower surface of the blanket 1-1 has a Velcro lining, and the inner surface of the straps 1-2 has a hook-and-loop lining. Together, these securely wrap the warming blanket 1 around the patient's arm. On the inner surface of the warming blanket 1, a rectangular array of micro-vibration motors 3 is embedded and fixed. Composed of multiple micro-vibration motors, these motors generate vibrations of different frequencies and intensities to stimulate the patient's arm. The pneumatic touch component 2 is located between the miniature vibration motor array 3. An air tube 2-1 is fixed inside the cotton blanket 1-1, and several manifolds 2-2 are fixed through its sidewall. A straight tube 2-4 is fixed to the end of each manifold 2-2. Multiple silicone airbags 2-3 are arranged in a linear array on the side of the straight tube 2-4 away from the cotton blanket 1-1, and the internal spaces of the straight tube 2-4, silicone airbags 2-3, and manifolds 2-2 are interconnected. The end of the air tube 2-1 away from the manifold 2-2 is connected to a miniature air pump. When the miniature air pump operates, gas enters the silicone airbags 2-3 through the air tube 2-1 and manifolds 2-2, causing them to inflate and touch the patient's arm, generating a tactile stimulus. A flexible pressure sensor is fixed to the end of the silicone airbag 2-3 closest to the body to monitor the touch pressure. The sound stimulation component 4 is fixed to the bottom surface of the cotton blanket 1-1. The inner wall of the internally threaded tube 4-1 is threaded, and the outer shell of the Bluetooth speaker 4-2 has threads that match the internal threads of the tube 4-1. The two are screwed together to secure the component. The Bluetooth speaker 4-2 can play different types of sounds to provide sound stimulation to the patient. Multiple temperature sensors are installed on the inner surface of the cotton blanket 1-1 to monitor the temperature of the graphene heating wire 1-3 and the patient's body temperature, ensuring a suitable temperature. Multiple battery blocks are installed on the outer surface of the cotton blanket 1-1 to power the micro-vibration motor array 3 and the pneumatic touch component 2.

[0019] When using the device post-surgery, the warming blanket 1 is first wrapped around the patient's arm and secured with bandages 1-2. The graphene heating wire 1-3 is then activated, slowly heating the arm to a suitable temperature to provide warmth. Initially, the micro-vibration motor array 3 vibrates at a low frequency and intensity, while the silicone airbags 2-3 of the pneumatic touch component 2 intermittently expand and touch the patient's arm with low pressure. A Bluetooth speaker 4-2 plays gentle, soothing sounds, providing gradual stimulation. As the patient's sensation gradually returns, the vibration frequency and intensity of the micro-vibration motor array 3 are gradually increased, along with the touch frequency and pressure of the pneumatic touch component 2, according to a preset program or the instructions of medical staff. Simultaneously, the sound type and volume of the Bluetooth speaker 4-2 are adjusted to achieve patterned stimulation. Throughout the recovery process, the stimulation intensity is continuously adjusted based on the patient's progress, ensuring the intensity adapts to the recovery process. This comprehensive stimulation method helps shorten the patient's stay in the PACU, improves turnover rate, enhances the post-operative experience, and reduces confusion, anxiety, and discomfort.

[0020] Example 2: The device in this example is applied to a patient's leg. The cotton blanket 1-1 of the warming wrap 1 is also inlaid with graphene heating wires 1-3 through grooves 1-4. Three binding straps 1-2 on the right side engage with the magic nap on the lower surface of the cotton blanket 1-1 to secure the warming wrap 1 to the patient's leg. A micro-vibration motor array 3 is embedded inside the cotton blanket 1-1, and pneumatic touch components 2 are arranged between the micro-vibration motor array 3. An air tube 2-1 connects to a micro-air pump; gas enters the silicone airbag 2-3 via a manifold 2-2 and a straight tube 2-4. A flexible pressure sensor monitors the touch pressure. The internally threaded tube 4-1 and Bluetooth speaker 4-2 of the sound stimulation component 4 are fixed to the bottom of the cotton blanket 1-1 by screwing. The temperature sensor on the cotton blanket 1-1 and the battery block on the outside are responsible for temperature monitoring and power supply, respectively.

[0021] When using this device on the patient's leg post-surgery, first secure the warming blanket 1, then turn on the graphene heating wires 1-3 to raise the temperature. Initially, the micro-vibration motor array 3 vibrates at a low intensity, the pneumatic touch component 2 slowly touches the leg, and the Bluetooth speaker 4-2 plays gentle sounds, providing the patient with gentle initial stimulation. As sensation in the leg returns, the vibration of the micro-vibration motor array 3 is gradually increased according to a preset pattern, the touch frequency of the pneumatic touch component 2 is accelerated, and the pressure is increased. Simultaneously, the sound of the Bluetooth speaker 4-2 is adjusted to achieve gradual and patterned stimulation. The stimulation intensity is dynamically adjusted based on the patient's leg recovery progress to meet the needs of stimulation as the recovery process progresses. This comprehensive stimulation helps the patient regain sensation in their leg more quickly, reduces time spent in the PACU, and improves the patient's post-operative experience.

[0022] Example 3: This example applies the device to the patient's torso. The cotton blanket 1-1 of the warming wrap 1 provides warmth through graphene heating wires 1-3 embedded in grooves 1-4. Three binding straps 1-2, in conjunction with the Velcro surface, secure the device to the patient's torso. A micro-vibration motor array 3 and a pneumatic touch component 2 are distributed inside the cotton blanket 1-1. An air tube 2-1 connects to a micro-air pump to supply air to the silicone airbag 2-3. A flexible pressure sensor monitors the touch. The internally threaded tube 4-1 of the sound stimulation component 4 and a Bluetooth speaker 4-2 are fixed to the bottom of the cotton blanket 1-1. A temperature sensor on the cotton blanket 1-1 and an external battery block monitor the temperature and provide power, respectively. The device is used on the patient's torso after surgery. After securing the warming wrap 1, heating is activated. Initially, the micro-vibration motor array 3 vibrates at a low frequency and low intensity, the pneumatic touch component 2 gently touches the torso, and the Bluetooth speaker 4-2 plays soothing sounds. As trunk sensation recovers, the vibration intensity and frequency of the micro-vibration motor array 3 are gradually increased according to a preset program, accelerating the contact speed and increasing the pressure of the pneumatic touch component 2, while simultaneously adjusting the audio content of the Bluetooth speaker 4-2. The stimulation intensity is adjusted in real time based on the patient's trunk recovery status, achieving gradual, patterned stimulation that adjusts in intensity according to the recovery process. This helps patients regain trunk sensation more quickly, improves turnover rate in the PACU, and enhances the postoperative experience. Based on the above description, the workflow of this technical solution is explained as follows: This rapid recovery device for post-anesthesia patient sensation is applied to parts of the patient's body, including but not limited to the arms, legs, and torso. The workflow is as follows: First, a warming blanket 1 is wrapped around the corresponding part of the patient's body and secured using three straps 1-2 on the right side surface of the blanket 1-1. The Velcro side sewn on the lower surface of the blanket 1-1 cooperates with the Velcro side sewn on the inner surface of the straps 1-2 to ensure the blanket adheres firmly to the patient's body. Then, the graphene heating wire 1-3 embedded in the groove 1-4 on the inner surface of the blanket 1-1 is activated. The temperature sensor installed on the inner surface of the blanket 1-1 begins to work, monitoring the temperature of the graphene heating wire 1-3 and the patient's body temperature in real time to ensure the temperature is within a suitable range, creating a warm and comfortable environment for the patient, promoting blood circulation, and creating favorable conditions for subsequent stimulation and recovery. On the inner surface of the warming blanket 1, a fixed array of miniature vibration motors 3 is started. This array consists of multiple miniature vibration motors arranged in a rectangular array. In the initial stage, it vibrates at a low frequency and intensity, generating preliminary vibration stimulation on the corresponding parts of the patient's body. This low-intensity vibration can gently awaken the patient's sensory nerves.

[0023] At the same time, the pneumatic touch component 2 located between the micro vibration motor array 3 starts to work. The end of the trachea 2-1 away from the manifold 2-2 is connected to the micro air pump. The micro air pump pumps gas into the trachea 2-1. The gas enters the straight tube 2-4 through several manifolds 2-2 that are fixed to the side wall of the trachea 2-1. Since the internal spaces of the straight tube 2-4, the silicone airbags 2-3 and the manifolds 2-2 are all interconnected, the gas finally enters the multiple silicone airbags 2-3 that are fixed to the side of the straight tube 2-4 away from the cotton blanket 1-1 and are arranged in a linear array. This causes the silicone airbags 2-3 to inflate and intermittently touch the patient's body. The flexible pressure sensor fixed to the end of the silicone airbag 2-3 near the human body monitors the touch pressure in real time to ensure that the touch force is moderate and will not cause excessive stimulation to the patient. This pneumatic touch works in conjunction with the vibration of the micro vibration motor to stimulate the patient's body in different ways. The sound stimulation component 4, fixed to the bottom surface of the cotton blanket 1-1, also begins to function. By screwing the Bluetooth speaker 4-2, which is fixed to the internal thread tube 4-1, it plays sounds of a specific type and volume. The threads on the inner wall of the internal thread tube 4-1 and the matching threads on the outer shell of the Bluetooth speaker 4-2 ensure a secure connection between the two. The sound stimulation can further activate the patient's auditory nerves and form a combined effect with the vibration and touch stimulation on the body, promoting the recovery of the patient's bodily perception.

[0024] As the patient gradually regains sensation, the device adjusts the stimulation intensity according to a pre-set program or instructions from medical staff. The micro-vibration motor array 3 gradually increases the frequency and intensity of vibration, while the pneumatic touch component 2 accelerates the contact frequency of the silicone airbags 2-3 and appropriately increases the contact pressure. Simultaneously, the Bluetooth speaker 4-2 adjusts the type and volume of the played sound as needed, achieving a patterned stimulation method. This patterned stimulation is designed based on the natural process of the patient's recovery and the characteristics of their neural responses, helping to more effectively promote the recovery of sensation. Throughout the recovery process, a temperature sensor continuously monitors the temperature. Multiple battery blocks installed on the outer surface of the cotton blanket 1-1, powering the micro-vibration motor array 3 and the pneumatic touch component 2, ensure the device's power supply. Medical staff can manually adjust various parameters of the device based on information from the temperature sensor and the patient's actual response, ensuring that the stimulation intensity always matches the patient's recovery process. This comprehensive, gradual, and recovery-adaptive stimulation method helps patients regain sensation more quickly, shortens their stay in the PACU, increases turnover rate, improves the postoperative experience, and reduces confusion, anxiety, and discomfort.
