Description

Technical Field

[0001] This invention relates to the field of grip ball technology, specifically to an intelligent PICC grip ball. Background Technology

[0002] Grip balls, also known as stress balls or venting balls, are primarily used to strengthen fingers and arms. They are small enough to fit comfortably in the palm of your hand. When you squeeze the ball, you can feel the pressure on your fingers. After squeezing it repeatedly, you'll feel a tingling and warm sensation in your palm, followed by a comfortable feeling. This is because the flexible ball deforms and fills your palm when you squeeze it, and the alternating squeezing and releasing effectively stimulates various acupoints on the palm, promoting blood circulation and achieving a health-promoting effect. To prevent PICC-related thrombosis in PICC-placed patients, grip balls are provided to every new patient with instructions on their use, thus reducing the risk of PICC-related thrombosis.

[0003] Chinese patent CN214074922U discloses a PICC grip strength ball, including a grip strength ball with an internal cavity. A pressure rod is fixedly connected to the left side of the cavity's inner wall, and a pressure block is fixedly connected to the surface of the pressure rod. A first spring is fixedly connected to the right side of the pressure block, and a top plate is fixedly connected to the side of the first spring away from the pressure block. A top rod is fixedly connected to the right side of the top plate, and a baffle is fixedly connected to the right side of the top rod after passing through the side wall of the cavity. By setting a pressure rod inside the grip strength ball, and cooperating with the pressure block and the first spring on the pressure rod, it can exercise grip strength. By setting a pressure sensor inside the cavity, and cooperating with the pressure rod to squeeze the pressure sensor, an indicator light can be lit, thereby prompting the patient to apply the required pressure.

[0004] In actual use, the aforementioned patents lack direct feedback and tactile sensation during finger operation, making it difficult for patients to accurately perceive the position, force, and range of motion of their fingers. This results in a lack of clear training effects and feedback on physical signs, making it difficult to know whether effective or excessive training has been conducted, leading to poor rehabilitation training results for patients. Therefore, they cannot meet the existing needs. In response, we have proposed an intelligent PICC grip ball. Summary of the Invention

A pressure sensor generates a pressure signal and transmits it to the control system. The control system then controls a speaker to issue a reminder, prompting the patient that the required grip strength has been reached. This ensures that each grip strength has a therapeutic effect, avoiding the possibility of ineffective exercise.

Detailed Implementation

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments 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.

[0047] To address the problem that existing patents lack direct feedback and tactile sensation during practical use, making it difficult for patients to accurately perceive finger position, force, and range of motion, thus resulting in a lack of clear training effects and bodily feedback, and making it difficult to determine whether effective or excessive training has been performed, ultimately leading to poor rehabilitation outcomes, please refer to [link to relevant documentation]. Figures 1-7 This embodiment provides the following technical solution:

[0048] The intelligent PICC grip ball includes a hand gripping part 2 and a finger gripping part 1. The hand gripping part 2 has a storage cavity, and a support mechanism 3 is installed inside the storage cavity. Multiple LED lights 4 are evenly spaced on the surface of the hand gripping part 2. The finger gripping part 1 is mounted on the hand gripping part 2 and has a control system. The finger gripping part 1 has a set of through holes 21 for easy finger insertion. The hand gripping part 2 and the finger gripping part 1 are made of silicone material. The front of the finger gripping part 1 has a display screen 6, and speakers 5 are located on both sides of the display screen 6. A control button is located below the display screen 6. The back of the finger gripping part 1 has an installation cavity 7, which houses a battery. The battery allows the patient to exercise outdoors. The LED lights 4 can emit colorful lights and can play music through the speakers 5 as needed. This allows the patient to exercise with the intelligent PICC gripping ball while also enjoying entertainment, preventing boredom from prolonged use and ensuring effective training.

[0049] The support mechanism 3 includes a vertical support component 31, a horizontal support component 32, and a threaded rod 33. The vertical support component 31 is fixed in the storage cavity inside the gripping part 2. Multiple horizontal support components 32 are provided at equal intervals on the outer side of the storage cavity inside the gripping part 2. Each horizontal support component 32 is threaded with a threaded rod 33.

[0050] The vertical support assembly 31 includes a movable rod 311, a vertical tube 312, a partition 313, a first spring 314, and a first fixed rod 315. The partition 313 is fixed to the center of the vertical tube 312. The first spring 314 is installed on both the upper and lower surfaces of the partition 313. The end of the first spring 314 away from the partition 313 is fixed to the bottom of the movable rod 311. The top of the movable rod 311 passes through the upper and lower ends of the vertical tube 312 and is fixed to the top and bottom of the gripping part 2, respectively. The first fixed rod 315 is provided on the inner side of the first spring 314. The movable rod 311 is movably installed on the outer side of the first fixed rod 315.

[0051] The transverse support assembly 32 includes a transverse tube 321, a trigger rod 322, a second fixing rod 323, a second spring 324, a fixing tube 325, and a threaded hole 326. The second fixing rod 323 is fixed inside the transverse tube 321. Both the second fixing rod 323 and the fixing tube 325 are provided with threaded holes 326. The second spring 324 is provided on the outside of the second fixing rod 323. One end of the second spring 324 is fixed to the fixing tube 325, and the other end is fixed to the fixing tube 325. The outside of the fixing tube 325 is fixed. With a trigger lever 322, when the size needs to be adjusted to be smaller, rotate the threaded rod 33 clockwise so that the threaded rod 33 moves inward in the threaded hole 326, retracting the gripping part 2 inward and reducing its size. When the size needs to be adjusted to be larger, rotate the threaded rod 33 counterclockwise so that the threaded rod 33 moves outward in the threaded hole 326 and increases the size of the gripping part 2. This allows the PICC grip ball to be adapted to different people, and patients with large or small hands can use it, improving its practicality.

[0052] A cavity 327 is provided inside the fixed tube 325. A pressure sensor 328 is installed at the bottom of the cavity 327. A fixed plate 329 is fixed to the outer surface of the fixed tube 325. An infrared sensor counter 320 is installed on the fixed plate 329. The position of the infrared sensor counter 320 corresponds to the position of the trigger rod 322. The pressure sensor 328 is a PT124G-111. The pressure sensor 328 is used to generate a pressure signal when the gripping part 2 deforms and transmits the pressure signal to the control system. The control system is used to obtain the pressure value corresponding to the pressure signal. In use, the patient's five fingers pass through the through hole 21 and grasp the gripping part 2. At this time, the patient's five fingers squeeze the gripping part 2, causing the movable rod 311 to retract inward. The horizontal tube 321 retracts inward under the pressure of the fingers, generating pressure under the action of the second spring 324. The force causes the second fixing rod 323 to move within the cavity 327 of the fixing tube 325 and come into contact with the pressure sensor 328. The pressure sensor 328 is compressed, generating a pressure signal which is transmitted to the control system. The control system then controls the speaker 5 to issue a reminder, indicating to the patient that the required force has been applied. This ensures that each grip force is effective and avoids ineffective training. Simultaneously, the horizontal tube 321, under the elastic force of the second spring 324, moves the trigger rod 322, causing it to come into contact with the infrared sensor counter 320. The infrared sensor counter 320 counts the patient's training progress and displays the count on the display screen 6. This counts the number of times the patient grips the ball each day, preventing the patient from failing to reach the required daily grip volume and affecting the effectiveness of the treatment.

[0053] Control system, including:

[0054] The data processing module is used to receive pressure data from the pressure sensor 328 and to analyze and judge the received pressure data.

[0055] The display module is used to display the number of times the patient uses the PICC grip ball for exercise and the pressure data from the pressure sensor 328;

[0056] The timing module is used to set the time for the patient to exercise with the PICC grip ball and to continuously time the real-time time of the patient's use of the PICC grip ball.

[0057] The alarm module is used to emit corresponding alarm signals through speaker 5 based on the analysis and judgment results.

[0058] The data processing module includes:

[0059] The data acquisition module is used to acquire pressure data from the pressure sensor 328 and transmit the acquired pressure data to the data analysis module.

[0060] The data analysis module is used to process the pressure data of the pressure sensor 328 to obtain the pressure value corresponding to the pressure signal, and to analyze the grip force applied by the patient when the PICC grip ball deforms.

[0061] The data assessment module is used to determine whether a patient has performed effective exercise based on the grip force applied when the PICC grip ball deforms.

[0062] The working process of the control system specifically includes:

[0063] First, the timing module is used to set the time for the patient to exercise with the PICC grip ball, and the real-time time of the patient's use of the PICC grip ball is continuously timed.

[0064] The system receives pressure data from the pressure sensor 328, processes the pressure data from the pressure sensor 328 to obtain the pressure value corresponding to the pressure signal, and analyzes the grip force applied by the patient when the PICC grip ball deforms.

[0065] The effectiveness of exercise can be determined by the grip force applied when the PICC grip ball deforms.

[0066] If the exercise is effective, the result will be displayed on the screen 6. If the exercise is not effective, an audible and visual alarm will be triggered by the speaker 5. This will allow the patient to understand their training progress and avoid the possibility of poor rehabilitation results due to a lack of clear exercise effects and physical signs, making it difficult to know whether the exercise has been effective or excessive.

[0067] Working principle: When using the intelligent PICC grip ball of this invention, according to... Figure 1 Figure 8 includes the following steps:

[0068] Step 1: Based on the size of the patient's hand, rotate the threaded rod 33 so that the threaded rod 33 moves within the threaded hole 326, and adjust the size of the hand gripping part 2 until it fits the patient's hand size. This allows the PICC gripping ball to be adapted to different people, and patients with large or small hands can use it, thus improving its practicality.

[0069] Step 2: After the size adjustment is completed, the patient's five fingers pass through the through hole 21 and grasp the gripping part 2. At this time, the patient's five fingers squeeze the gripping part 2, and the elastic force of the first spring 314 causes the movable rod 311 to retract inward. At this time, the second spring 324 at the horizontal tube 321 retracts inward under the pressure of the fingers.

[0070] Step 3: Under the action of the second spring 324, the gripping part 2 generates pressure, which causes the second fixing rod 323 to move in the cavity 327 inside the fixing tube 325 and contact the pressure sensor 328. The pressure sensor 328 is squeezed, thereby generating a pressure signal and transmitting the pressure signal to the control system. At the same time, the horizontal tube 321 drives the trigger rod 322 to move under the elastic force of the second spring 324, so that the trigger rod 322 contacts the infrared sensing counter 320. The infrared sensing counter 320 counts the patient's training status and displays the counted number on the display screen 6. It can count the number of times the patient grips the ball every day to prevent the patient from failing to reach the daily ball grip volume and affecting the use effect.

[0071] Step 4: The control system acquires the pressure data from the pressure sensor 328, processes the pressure data from the pressure sensor 328 to obtain the pressure value corresponding to the pressure signal, and analyzes the grip force applied by the patient when the PICC grip ball deforms.

[0072] Step 5: Determine whether the patient has performed effective exercise based on the grip force applied when the PICC grip ball deforms, and display the result on display screen 6.

[0073] In summary, the intelligent PICC grip ball of this invention, by rotating the threaded rod 33, allows it to move within the threaded hole 326, adjusting the size of the gripping part 2. This makes the PICC grip ball suitable for different people, including patients with large or small hands, improving its practicality. The horizontal tube 321, under the elastic force of the second spring 324, moves the trigger rod 322, causing it to contact the infrared sensor counter 320. The infrared sensor counter 320 counts the patient's training progress and displays the count on the display screen 6, enabling the counting of the number of times the patient grips the ball daily, preventing patients from failing to reach their training goals. The daily amount of gripping affects the effectiveness of the exercise. Pressure sensor 328 generates a pressure signal and transmits it to the control system. The control system then controls speaker 5 to issue a reminder, indicating to the patient that the required force has been applied. This ensures that each gripping effort is effective and avoids ineffective training. LED lights 4 and speaker 5 emit colorful lights and play music, respectively, allowing patients to enjoy the exercise while using the intelligent PICC grip ball. This prevents patients from becoming bored with long-term use of the intelligent PICC grip ball and thus avoids affecting the training effect.

[0074] Based on the foregoing embodiments, the data processing module further includes:

[0075] The biometric identification submodule is used to acquire infrared detection data from the infrared sensor, determine the biometrics based on the infrared detection data, identify whether the patient is performing the grip strength operation, acquire the patient's fingerprint, and distinguish and store the measurement data of PICC grip strength ball exercise according to the fingerprint identification of the patient;

[0076] The single grip pressure curve construction submodule is used to correlate pressure data with time data through a timer when the patient performs grip force operation, and construct a pressure curve that changes over time; the curve is segmented according to the changes in the peaks and troughs of the pressure curve, ensuring that each segmented curve segment includes a pressure change process from the trough to the peak, thus obtaining the single grip pressure curve;

[0077] The effectiveness evaluation submodule is used to set the evaluation cycle. For the same patient's first PICC grip ball exercise measurement data on the first day of adjacent evaluation cycles, it compares the single grip pressure curves of the same sequence from the two exercises, determining the smaller of the two peaks in the same sequence, and the pressure duration required to reach that smaller peak pressure. The exercise effectiveness index is calculated using the following formula and announced via speaker:

[0078]

[0079] in, This represents the training effectiveness index for adjacent evaluation periods. This refers to the number of grip compressions performed during the first PICC grip ball exercise on the first day of the previous assessment cycle within an adjacent assessment period. This refers to the number of grip compressions performed during the first PICC grip ball exercise on the first day of the next assessment cycle within an adjacent assessment period. The minimum number of grip compressions during the first PICC grip ball exercise on the first day of an adjacent assessment cycle, i.e.: ; This is the first PICC grip ball exercise on the first day of the previous cycle. The duration of pressure application for each grip. The first PICC grip ball exercise on the first day of the next cycle The duration of pressure application for each grip. and To set the weighting coefficients, and .

[0080] Specifically, infrared biometrics are used to identify the user as a patient, not a mechanical device or robot. Fingerprint recognition is used to differentiate users, and the exercise measurement data is stored and managed separately for each user, facilitating data retrieval and analysis for specific patients. The data measurement is correlated with time to construct a pressure change curve for the patient's exercise. A single grip pressure is defined as the process from lowest to highest pressure, and curve segmentation is performed to obtain each single grip pressure curve, meaning each single grip pressure curve includes the entire process from low to high pressure, thus providing a basis for analyzing changes in single grip pressure. The number of grip pressures per patient's PICC grip ball exercise (i.e., including multiple...) The single grip pressure curve may vary, and the duration of each grip pressure increase from low to high also differs, with the general trend being that the duration increases towards the end. The peak pressure of each single grip may also differ. The above formula uses the first PICC grip ball exercise in adjacent cycles as the analysis object to avoid analytical errors caused by differences in fatigue levels due to multiple consecutive exercises. The evaluation cycle is generally calculated in days because patients have time to recover their physical condition after resting overnight. For example, the evaluation can be conducted once a day using the first PICC grip ball exercise of the previous day and the current day, or once every three days, or once a week or month. The evaluation provides patients with an intuitive understanding of their exercise effect and improves their user experience.

[0081] Based on the foregoing embodiments, the data processing module further includes:

[0082] The data acquisition submodule is used to acquire the palm temperature and ambient temperature from the temperature sensor, and at the same time acquire heart rate data from the heart rate sensor.

[0083] The energy consumption assessment submodule is used to input hand temperature, heart rate data and ambient temperature into a pre-trained exercise energy consumption assessment model, and output the calorie consumption value.

[0084] The status assessment submodule is used to calculate and assess the patient's status using the following formula for the same patient:

[0085]

[0086] in, For patient status indicators, This represents the number of calories burned during the current hand pressure. For the first The number of calories burned in each historical grip compression. The patient's historical number of hand grips;

[0087] The alert submodule is used to compare the current patient status indicators with the indicator thresholds. If the patient status indicator exceeds the indicator threshold, an alert message is issued.

[0088] Specifically, when patients use PICC hand grip balls for exercise, the friction between their hands and the grip ball generates heat as the number of uses increases, causing their palm temperature to rise. This means that the patient's palm temperature and heart rate change with environmental variations. Furthermore, different patients have different physical conditions, resulting in variations in palm temperature and heart rate during exercise. By monitoring changes in palm temperature, heart rate, and ambient temperature, a sports energy consumption assessment model can indirectly assess calorie consumption. Based on the calories consumed during current and historical exercise, the aforementioned formula is used to calculate the patient's status index. If the patient's status index exceeds a threshold, it indicates an abnormality in the patient's current state, and a warning message is issued, prompting the patient to pay attention. Additionally, the calorie consumption assessment can be adjusted according to changes in ambient temperature, thus ensuring the reliability of the assessment results. The sports energy consumption assessment model can use a neural network as its foundation, employing a training dataset composed of historical monitoring data for training, enabling the model to monitor exercise effectiveness.
