Description

Technical Field

[0001] The utility model relates to the medical field, and specifically relates to an exercise device with a bidirectional adjustable function for exercising the hands of patients. Background Technique

[0002] Grip strength, commonly known as hand strength, is the muscle strength from the hand, forearm, and upper limb. Grip strength reflects the overall muscle health status and motor ability, and is a currently proven and widely used muscle strength measurement tool. Grip strength has been proposed as a biomarker for current and future health status. There are many people with decreased grip strength, and the harm is serious.

[0003] (1) Decreased grip strength in the elderly population: Currently, the aging level in China is at the upper-middle level globally and shows a gradually increasing trend. In 2023, the proportion of the elderly population aged 65 and above was 15.4%; after the age of 65, for every ten-year increase in the age of the elderly, their grip strength will decrease by 3.5 kg. In particular, the grip strength of men decreases more than that of women for each additional year (0.53 kg vs 0.23 kg).

[0004] (2) Decreased grip strength in patients with cardiovascular diseases: Grip strength can be used as a screening tool for cardiovascular risk stratification, is positively correlated with cardiopulmonary function, and is a recognized protective factor for cardiovascular diseases. The grip strength of patients with coronary heart disease is lower than that of non-coronary heart disease patients; a decrease in grip strength increases the related cardiovascular mortality and the incidence of cardiovascular diseases, shortens the life expectancy; increases the risk of heart failure and the re-hospitalization rate of heart failure; the grip strength of the limb on the side of the body after pacemaker implantation decreases.

[0005] (3) Patients with cerebrovascular diseases: Patients with cerebral infarction and cerebral hemorrhage will bring sequelae such as hemiplegia, weakness, and inflexibility of the hands to the patients;

[0006] In addition, there is a correlation between lower grip strength and a higher risk of malnutrition, osteoporosis, falls, fragility fractures, cognitive impairment, depression and other diseases in middle-aged and elderly inpatients;

[0007] Hand exercises can improve grip strength, finger flexibility and hand-eye coordination; they are even crucial for the recovery of cardiopulmonary function. At present, clinically, patients are encouraged to clench their fists with their bare hands or use grip balls to exercise. The grip strength and number of times the patients clench their fists are also recorded, which can improve the grip strength of patients to varying degrees. However, there are still advanced medical management models that are difficult to meet the current development. There are the following problems: the strength of the grip ball cannot be adjusted for products on the market. When the grip strength is weakened, there is too much resistance, making it difficult to hold the grip in place and failing to achieve the effect of exercise; the distribution of hand muscles and the functions of various parts are not considered, and the effect of reverse stretching of the five fingers is ignored: pulling the thumb backward to stretch the thumb flexor; pulling the remaining four fingers to stretch the wrist and metacarpophalangeal joints, and stretching the common flexor of the digitorum. Therefore, according to the distribution of hand muscle groups and the recovery of muscle strength, it is necessary to set up a device that gradually increases the palm pressure and reverse pulling force according to the recovery of hand grip strength, and dynamically changes the exercise plan.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0033] Please refer to Figure 1 - Figure 6 , the present utility model provides an exercise device with a bidirectional adjustable function for patient hand exercise, including a finger exercise mechanism 1, an airbag massage mechanism 2 and a binding mechanism 3;

[0034] The finger exercise mechanism 1 is used to be placed on the wrist part of the patient and is triggered by the elastic inflation and deflation contraction of the airbag massage mechanism 2. The binding mechanism 3 is used to surround and set on the wrist part, thereby synchronously regulating the elastic contraction of the airbag massage mechanism 2;

[0035] The finger exercise mechanism 1 includes multi-joint rubber finger sleeves 11 sleeved on the fingers. An access base 12 is installed on the top side of the multi-joint rubber finger sleeves 11. A spring 13 for elastic tightening and expansion is connected to the top end of the access base 12;

[0036] Both ends of each independent spring 13 are respectively arranged at the end positions of the tube-connected rubber finger sleeves 11, and the other ends of the springs 13 are respectively provided with linkage hooks 14 for tying. A rubber coating sleeve 15 is attached and installed on the back of the linkage hooks 14.

[0037] In this embodiment: An airbag massage mechanism 2 is also installed on the surface of the rubber coating sleeve 15. The airbag massage mechanism 2 includes airbag columns 21 attached to both side edges of the top of the rubber coating sleeve 15. An airbag ball 22 for connection is provided at the end position of the airbag columns 21. A number of rubber pressing arc pieces 23 are successively arranged at the end of the airbag ball 22.

[0038] Under the combined action of the adopted airbag ball 22 and the specific rubber pressing arc pieces 23, the problem of the recovery training for the disease that the patient's fingers cannot independently make a fist and stretch is solved

[0039] In this embodiment: One end of each rubber pressing arc piece 23 is respectively arranged on the surface of the specified airbag ball 22. The bottom of the rubber pressing arc piece 23 corresponds to the slot space of the specified rubber finger sleeve 11. A palm pressing ball 24 is also installed on the back side edge of the airbag column 21. A thumb pressing airbag ball 25 is hinged to the side of the palm pressing ball 24. An arc-shaped adjusting ball 26 is provided at the end position of the thumb pressing airbag ball 25. The bottom of the arc-shaped adjusting ball 26 is arranged for the specified thumb pressing.

[0040] The airbag column 21, the palm pressing ball 24, and the thumb pressing airbag ball 25 adopt different pipe connections for air transmission, with refined structural control.

[0041] In this embodiment: At the end position of the palm pressing ball 24, a connecting sleeve 27 for pipe connection is hermetically connected. On the back of the rubber finger cot 11, a binding mechanism 3 is also installed. The binding mechanism 3 includes a constricting wristband 31 installed at the end of the rubber finger cot 11. A stretch tightening band 32 for binding is sleeved on the surface of the constricting wristband 31, and a mother-daughter magic tape 33 for pasting is provided at the edge of the stretch tightening band 32.

[0042] The adopted stretch tightening band 32 and mother-daughter magic tape 33 achieve the effect of binding and connecting to the patient's wrist and forearm, providing a good environment for subsequent blood pressure measurement or other instrument treatments.

[0043] In this embodiment: At the top of the airbag column 21, a control mechanism 4 is fitted and installed. The control mechanism 4 includes an arc-shaped rubber pad 41 fitted on the surface of the airbag column 21. In the middle of the top of the arc-shaped rubber pad 41, a detector 42 for airbag pressure adaptation detection is fitted and installed. A counter 43 is also installed on the side of the detector 42.

[0044] The main functions of the adopted detector 42 and counter 43 are to calculate the number of times the patient exercises the finger gripping state.

[0045] In this embodiment: In the middle of the arc-shaped rubber pad 41, a data acquisition QR code 44 is also provided. One end of the connecting sleeve 27 is piped to a two-way air exchange mechanism 5. The two-way air exchange mechanism 5 includes an air charging and discharging frequency pump 51 connected to the connecting sleeve 27.

[0046] The adopted air charging and discharging frequency pump 51 mainly has a resistance structure with frequency control. This kind of air pump is relatively common and more convenient to use.

[0047] In this embodiment: The airbag column 21, the airbag ball 22, and the thumb pressing airbag ball 25 are all hermetically connected to the palm pressing ball 24.

[0048] Multiple airbags have different application effects, and the gas transmission efficiency between them is more convenient.

[0049] First step one: Let the hand that the patient needs to exercise be placed into this glove.

[0050] At this time, several fingers at the wrist part: the thumb, index finger, ring finger, little finger, and middle finger are all placed into the multi-joint rubber finger cot 11. And this form of finger cot is made of hollow rubber material inside, which just holds them. To prevent stuffiness, the position of the hand surface is open, and the position of the palm is bound by the arc-shaped rubber pad 41.

[0051] After insertion, let the multiple rubber pressing arc pieces 23 swing upwards, because when the airbag is not expanded and inflated, there is less air, so each rubber pressing arc piece 23 moves involuntarily toward the center of the palm of the hand. After it is turned over and put on;

[0052] Step 2: Wrist binding;

[0053] In this stage, the corresponding elastic tightening belt 32 is wound, and the corresponding Velcro 33 is further turned over in the deflection direction, and then based on the specific tightening of the elastic tightening belt 32, the tightening wristband 31 is adjusted to cover the patient's wrist forearm;

[0054] Step 3: Massage exercise:

[0055] The user only needs to control the inflation and deflation frequency of the inflation and deflation frequency pump 51, and then the gas will first be injected into the position of the palm pressing ball 24 from one end of the connecting sleeve 27, and finally ventilated to the position of the specific airbag column 21, and then after being triggered, the spherical structure of the airbag ball 22 between them will be expanded, and the linked rubber pressing arc piece 23 will be expanded downward until the pressing hand is gradually unfolded from the fist state;

[0056] The deployment gas is first generated from the position where the palm presses the ball 24, and then diverted to the thumb pressing the airbag ball 25, then to the airbag column 21 and then to the airbag ball 22, so that multiple rubber pressing arc pieces 23 can control it;

[0057] Step 4: Contraction and reduction:

[0058] In this process, after the airbag shrinks, the handle changes from a gripping state to a shrinking state. This process is achieved by the shrinkage and traction of the elastically tightened and expanded spring 13 arranged on the outside of the multi-jointed rubber finger sleeve 11. By utilizing the connection state of the specific linkage hook 14 and the front-end access base 12, during the process, according to the corresponding access base 12, the front and rear shrinking states of the elastically tightened and expanded spring 13 can be restrained by the corresponding access base 12. The multiple multi-jointed rubber finger sleeves 11 are first subjected to the gas pressure bending, and the spring 13 is passively stretched. Finally, the air pressure disappears, and the spring 13 turns the entire multiple independent multi-jointed rubber finger sleeves 11 into a fisting state. This has the advantage that as long as the gas is large enough, the elastic force characteristics generated can better achieve traction;

[0059] Step 5: Intelligent monitoring, the number of times the hand is gripped and stretched is measured by the counter 43, and the number of times the hand is gripped and stretched is measured by the detector 42.

[0060] Step 6: Intelligent construction;

[0061] The main function is to cooperate with the cloud system based on the exercise data. What is utilized is the data acquisition QR code 44. In advance, a web cloud platform needs to be constructed, and the data is uploaded in advance to facilitate viewing of the user usage data.

[0062] It should be supplemented that in terms of pressure sensing, the following is used: for the piezoelectric film sensor, existing products can be adopted, such as LDT1-028K;

[0063] Other solutions in the prior art are also adopted for exercise counting. For example, a Hall sensor and a magnet are used. The Hall sensor and the magnet are symmetrically arranged on both sides of the hollow air cavity 3 respectively. The Hall sensor is connected to the microcomputer processing module 7. When the elastic sphere 1 is squeezed and deformed, causing the Hall sensor and the magnet to approach each other, the Hall sensor senses the magnetic field of the magnet and counts once. The Hall sensor can also adopt conventional products in the prior art, such as the 3144E switch-type Hall sensor. This product is equipped with an induction indicator light, and the induction indicator light will only light up after sensing the magnetic field, so that the user can be accurate;

[0064] The main effects achieved are: the number of effective exercises, the pressing force (contraction), and the force of spreading the five fingers can be recorded.

[0065] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
