Description

Technical Field

[0001] The invention relates to the technical field of grip balls, in particular to an intelligent PICC grip ball. Background Art

[0002] The grip ball, also known as the stress relief ball and the venting ball, is mainly used to exercise the finger and arm strength. The grip ball is not large and can be held in the palm of your hand. Hold the grip ball and squeeze it hard. You can feel the pressure of the grip ball on your fingers. Generally, if you hold it for N times continuously, you can feel the numbness and heat in your palms, and then you will feel very comfortable. Because when you squeeze the grip ball hard, the flexible ball is deformed and fills the palm. The palm is loosened and tightened, and the ball can effectively stimulate the major acupuncture points of the palm, promote blood circulation, and achieve the effect of exercise and health care. In order to prevent PICC-related thrombosis in patients with PICC catheterization, each new patient will be provided with a grip ball and instructed on its use to reduce the occurrence of PICC-related thrombosis.

[0003] A Chinese patent with publication number CN214074922U discloses a PICC grip ball, including a grip ball body, a cavity is opened inside the grip ball body, a pressure rod is fixedly connected to the left side of the inner wall of the cavity, 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, 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 arranging a pressure rod inside the grip ball body and cooperating with the pressure block and the first spring on the pressure rod, the grip strength can be exercised, and by arranging a pressure sensor inside the cavity and cooperating with the pressure rod to squeeze the pressure sensor, the effect of lighting up the indicator light can be achieved, thereby prompting the patient that the strength has reached the requirement.

[0052] A cavity 327 is provided in the fixed tube 325, and a pressure sensor 328 is provided at the bottom of the cavity 327. A fixed plate 329 is fixed to the outer surface of the fixed tube 325, and an infrared induction counter 320 is provided on the fixed plate 329. The position of the infrared induction counter 320 corresponds to the position of the trigger rod 322. The model of the pressure sensor 328 is PT124G-111. The pressure sensor 328 is used to generate a pressure signal when the palm force part 2 is deformed, and transmit the pressure signal to the control system. The control system is used to obtain the pressure value corresponding to the pressure signal. When in use, the patient's five fingers pass through the through hole 21 to hold the palm force part 2. At this time, the patient's five fingers squeeze the palm force part 2, so that the movable rod 311 shrinks inwardly, and the cross tube 321 shrinks inwardly under the squeezing of the fingers, and a pressure is generated under the action of the second spring 324. The force is applied to the second fixing rod 323 so as to move in the cavity 327 in the fixing tube 325 and contact the pressure sensor 328. The pressure sensor 328 is squeezed to generate a pressure signal and transmit the pressure signal to the control system. The control system controls the speaker 5 to issue a reminder to remind the patient that the force has reached the requirement at this time, thereby ensuring that the grip strength each time can achieve the therapeutic effect and avoiding the possibility of ineffective exercise. At the same time, the cross 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 induction counter 320. The infrared induction 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 grip amount and affecting the use effect.

[0053] Control system, including:

[0054] A data processing module, used to receive pressure data from the pressure sensor 328, and analyze and judge the received pressure data;

[0055] A display module, used to display the number of times the patient exercises with the PICC grip ball and the pressure data of the pressure sensor 328;

[0056] A timing module is used to set the time for the patient to exercise with the PICC grip ball and continuously time the real-time time when the patient uses the PICC grip ball;

[0057] The alarm module is used to send out a corresponding alarm signal through the speaker 5 according to the results of analysis and judgment.

[0058] Data processing module, including:

[0059] A data acquisition module, used to acquire pressure data from the pressure sensor 328 and transmit the acquired pressure data to the data analysis module;

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

[0061] The data judgment module is used to judge whether the patient has performed effective exercise according to the grip force value applied when the PICC grip ball is deformed.

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

[0063] First, use the timing module to set the time for the patient to exercise with the PICC grip ball, and continuously count the real-time time that the patient uses the PICC grip ball;

[0064] Receiving pressure data from the pressure sensor 328, processing the pressure data from the pressure sensor 328 to obtain a pressure value corresponding to the pressure signal, and analyzing the grip force value applied by the patient when the PICC grip ball is deformed;

[0065] The grip force applied when the PICC grip ball is deformed is used to determine whether the patient has performed effective exercise;

[0066] If the effect of effective exercise is achieved, the result will be displayed on the display screen 6. If the effect of effective exercise is not achieved, an audible and visual alarm will be issued through the speaker 5, so that the patient can understand his or her training situation and avoid the lack of clear exercise effect and physical sign feedback, making it difficult to know whether effective exercise has been performed or excessive exercise, which may lead to the possibility of poor effect of patient rehabilitation exercise.

[0067] Working principle: When using the intelligent PICC grip ball of the present invention, Figure 1-Figure 7 , including the following steps:

[0068] Step 1: According to the size of the patient's hand, the threaded rod 33 is rotated to move the threaded rod 33 in the threaded hole 326, and the size of the hand grip part 2 is adjusted until it fits the size of the patient's hand, so that the PICC grip ball can be adapted to different groups of people, and can be used by patients with large or small hands, thereby improving practicality;

[0069] Step 2: After the size adjustment is completed, the patient passes five fingers through the through hole 21 to hold the palm force part 2. At this time, the patient's five fingers squeeze the palm force part 2, and the movable rod 311 shrinks inwardly under the elastic force of the first spring 314. At this time, the second spring 324 at the cross tube 321 shrinks inwardly under the squeezing of the fingers;

[0070] Step 3: The palm of the hand generates pressure on the force-applying part 2 under the action of the second spring 324, so that the second fixing rod 323 moves in the cavity 327 in the fixing tube 325 and contacts the pressure sensor 328. The pressure sensor 328 is squeezed to generate a pressure signal and transmit the pressure signal to the control system. At the same time, the cross 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 induction counter 320. The infrared induction counter 320 counts the patient's training status and displays the counted number on the display screen 6, which can count the number of times the patient holds the ball every day, so as to prevent the patient from failing to reach the daily ball holding amount and affecting the use effect;

[0071] Step 4: The control system obtains the pressure data of the pressure sensor 328, processes the pressure data of the pressure sensor 328 to obtain the pressure value corresponding to the pressure signal, and analyzes the grip force value applied by the patient when the PICC grip ball is deformed;

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

[0073] In summary, the intelligent PICC grip ball of the present invention rotates the threaded rod 33 to move the threaded rod 33 in the threaded hole 326, and adjusts the size of the palm grip portion 2, so that the PICC grip ball can adapt to different groups of people and can be used by patients with large or small hands, thereby improving practicality. The transverse 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 induction counter 320. The infrared induction counter 320 counts the patient's training status and displays the counted number on the display screen 6, so as to count the number of times the patient grips the ball every day, thereby preventing the patient from failing to reach the target number. The amount of gripping the ball every day affects its use effect. The pressure sensor 328 generates a pressure signal and transmits the pressure signal to the control system. The control system controls the speaker 5 to issue a reminder to remind the patient that the strength has reached the requirement at this time, thereby ensuring that the size of each grip can achieve a therapeutic effect and avoid the possibility of ineffective exercise. The LED light 4 and the speaker 5 are set to emit colorful lights and play music respectively, so that patients can exercise with the intelligent PICC grip ball of the present invention while also taking into account the entertainment effect, thereby avoiding patients feeling bored with long-term use of the intelligent PICC grip ball for exercise, which affects the training effect.

[0074] Based on the above embodiment, the data processing module further includes:

[0075] The biometric identification submodule is used to obtain infrared detection data from the infrared sensor, make biometric judgment based on the infrared detection data, and determine whether the patient is performing the gripping operation; obtain the patient's fingerprint, and distinguish and store the measurement data of the PICC gripping ball exercise based on the fingerprint identification of the patient's identity;

[0076] The single grip pressure curve construction submodule is used to associate the pressure data with the time data through the timer when the patient performs the grip force operation, so as to construct a pressure curve that changes with time; the curve is segmented according to the changes in the peak and trough of the pressure curve, so as to ensure that each segmented curve segment includes a pressure change process from the trough to the peak, that is, to obtain a single grip pressure curve;

[0077] The effect evaluation submodule is used to set the evaluation cycle. For the first PICC grip ball exercise measurement data of the same patient on the first day of the adjacent evaluation cycle, the single grip pressure curves of the same order of the two exercises are compared according to the grip pressure order, and the pressure peak value of the smaller of the two peaks in the same order and the pressure duration respectively experienced to reach the smaller pressure peak value are determined. The exercise effect index is calculated using the following formula and announced through the speaker:

[0078]

[0079] in, is the exercise effect index of the adjacent evaluation cycle, The number of grip compressions during the first PICC grip ball exercise on the first day of the previous cycle in the adjacent assessment cycle. The number of grips and compressions during the first PICC grip ball exercise on the first day of the next cycle in the adjacent assessment cycle. The minimum number of grip compressions in the two grip compressions of the first PICC grip ball exercise on the first day of the adjacent assessment cycle, that is: ; The first PICC grip ball exercise on the first day of the previous cycle The duration of the compression of each grip, The first PICC grip ball exercise on the first day of the next cycle The duration of the compression of each grip, and is to set the weight coefficient, and .

[0080] Specifically, infrared biometric recognition is used to determine that the user is a patient, not a mechanical device or robot. Fingerprint recognition is used to distinguish users, and the exercise measurement data are stored and managed separately according to the different users, so as to facilitate data query or call analysis for specific patients. The data measurement is associated with time to construct a pressure change curve of the patient's exercise. The process from the lowest pressure to the peak pressure is used as a single grip pressure. The curve is segmented to obtain each single grip pressure curve, that is, the single grip pressure curve includes the whole process from low to high grip pressure, thereby providing a basis for the change analysis of single grip pressure. The number of grip pressures (that is, including multiple grip pressures) of the patient each time using the PICC grip ball exercise The single grip pressure curve may be different, and the duration of each grip pressure from low to high is also different. The general trend is that the later it is, the longer it takes. Each single pressure peak may also be different. The above formula uses the first PICC grip ball exercise in adjacent cycles as the analysis object, avoiding the analysis error caused by differences in fatigue levels caused by consecutive exercises. The evaluation cycle is generally measured in days, because the patient's physical condition recovers after a night of rest. For example, the first PICC grip ball exercise of the previous day and the current day is evaluated once a day, or it is evaluated every three days, or it can be evaluated once a week or month. The evaluation provides patients with an intuitive understanding of the effect of their own exercise and improves the patient's good experience.

[0081] Based on the above embodiment, the data processing module further includes:

[0082] The data acquisition submodule is used to obtain the palm temperature and ambient temperature of the temperature sensor, and obtain the heart rate data through the heart rate sensor;

[0083] The energy consumption evaluation submodule is used to input the palm temperature, heart rate data and ambient temperature into the sports energy consumption evaluation model based on the pre-trained sports energy consumption evaluation model, and output the consumed calorie value;

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

[0085]

[0086] in, is an indicator of patient status, The current number of calories consumed by gripping. For the The number of calories burned by the historical grip and pressing. The patient's historical grip-pressure times;

[0087] The warning submodule is used to compare the current patient status indicator with the indicator threshold. If the patient status indicator exceeds the indicator threshold, a warning message is issued.

[0088] Specifically, when the patient uses the PICC hand grip ball for exercise, as the number of times the hand gripper is used increases, the friction between the hand and the hand gripper will generate heat, causing the palm temperature to rise, that is, the patient's palm temperature and heart rate will change with the changes in the environment. In addition, the changes in palm temperature and heart rate during exercise will vary depending on the patient's physique. By monitoring the changes in palm temperature, heart rate and ambient temperature, the calorie consumption can be indirectly evaluated through the exercise energy consumption evaluation model. Based on the calories consumed by the current exercise and historical exercise, the patient's status index is calculated using the above formula. If the patient's status index exceeds the index threshold, it means that the patient's current state is abnormal, and a warning message is issued to prompt the patient to pay attention. In addition, the calorie consumption assessment can be adjusted according to the change in ambient temperature to ensure the reliability of the assessment results. Among them, the exercise energy consumption assessment model can use a neural network as the model basis, and use a training data set composed of historical monitoring data for the training of the exercise energy consumption assessment model, so that the exercise energy consumption assessment model can be used to realize exercise effect monitoring.
