Mechanical Stimulation Kit and Adaptive Capsule for Treatment of

Sarcopenia

TECHNICAL FIELD

The present invention relates to a medical device, in particular to an

external counterpulsation and local vibration stimulation kit and a capsule for

the treatment of sarcopenia.

BACKGROUND

Sarcopenia is a condition characterized by a decrease in muscle volume,

muscle strength, and somatic function. In 2016 sarcopenia received an

International Classification of Diseases (ICD-10) code (M62.84) from the World

Health Organization, which marked the recognition of sarcopenia as a new

disease. The prevalence of sarcopenia is about 10% in the elderly in

communities, up to 50% in the elderly over 80 years of age, and up to 30-50%

in the hospitalized elderly patient. Sarcopenia makes it difficult for the elderly

to complete various daily activities such as walking, sitting and standing, thus

increasing the risk of falls, disability rate and mortality.

Existing methods for the prevention and treatment of sarcopenia are

limited, mainly including nutritional intervention and resistance exercise, and

no drug can effectively prevent and treat such a disease. However, resistance

exercise is difficult to implement for most elderly people, especially the senile

elderly and these living in a nursing home and staying in hospital. The

whole-body vibration control (WBV) is a newly developed technology for the

prevention and treatment of sarcopenia, which can only be provided for the

elderly capable of standing constantly, thus making it infeasible for the elderly with severe sarcopenia. In addition, external counterpulsation (ECP) technology has been used clinically for more than 40 years, and several ECP devices have been introduced and mainly used to treat coronary heart disease, angina pectoris, congestive heart failure and ischemic stroke as an assistant treatment means. In recent years, it was found that the average blood flow of posterior tibial artery increased to (133±3.4) % of the basic state one hour after

ECP, which could improve the peripheral blood circulation.

The growth, repair and work of skeletal muscle cannot be performed

without blood supply and oxygen supply from capillary network. According to

the studies, patients with sarcopenia are manifested with sparse capillary

network and microcirculation disturbance. The muscle function of patients with

sarcopenia can be improved by enhancing their microcirculation. Therefore,

there is an important research value and practical need to develop a device

and equipment to treat sarcopenia by improving the blood and oxygen supply

to skeletal muscles through in vitro stimulation.

SUMMARY

The technical problem to be solved by the present invention is to provide a

mechanical stimulation kit for the treatment of sarcopenia by accurately

applying a pressure and vibrating muscle tissues.

The technical solution for solving the technical problem of the present

invention is a mechanical stimulation kit for the treatment of sarcopenia,

comprising a sleeve, a connecting rod, a vibrating device, a deformable touch

plate, a pressure sensor, a control module, an air source system, and an

airbag, wherein one end of the sleeve is provided with an opening for accommodating the connecting rod, and the other end thereof is provided with the vibrating device that is fixed relative to the sleeve; one end of the connecting rod is connected to the vibrating device that drives a reciprocating motion of the connecting rod, and the other end thereof is arranged outside the sleeve and connected to the deformable touch plate; the pressure sensor is arranged on one side of the deformable touch plate facing away from the connecting rod and electrically connected to the control module that is connected to the air source system; the number of the airbag is one or more, and the air source system is connected to the airbag and can inject air into the airbag and exhaust air therefrom. Further, the mechanical stimulation kit for the treatment of sarcopenia comprises an ECG signal acquisition device that is electrically connected to the control module.

Specifically, the pressure sensor is a Jingchengpu FlY button-type pull

pressure sensor, and the deformable touch plate is made from a shape

memory polymer (SMP) material.

Further, the sleeve is internally provided with a push plate capable of

sliding along the axial direction thereof, the vibrating device is installed in the

sleeve, with one side of the vibrating device being fixedly connected to one

end of the sleeve and the other side thereof being connected to the push plate,

the vibrating device can drive a reciprocating motion of the push plate, and one

end of the connecting rod arranged inside the sleeve is connected to the push

plate.

Specifically, the vibrating device is a vibration motor, wherein the vibration

frequency of the vibration motor is 30-45 Hz and preferably 35-40 Hz, and the amplitude thereof is 1.0-2.0 mm and preferably 1.1-1.5 mm.

Specifically, an opening at one end of the sleeve is located at the center of

the end face of the sleeve, the sleeve is cylindrical, a cable of the pressure

sensor is laid inside the connecting rod, a chip is arranged in the sleeve, and a

control module is integrated on the chip.

The advantageous effects of the mechanical stimulation kit for the

treatment of sarcopenia are as follows: the extracorporeal counterpulsation

technology is used for improving microcirculation in peripheral skeletal muscle

tissues for the first time; while the improved microcirculation and

neuromuscular stimulation are used to achieve the intervention treatment of

sarcopenia. Meanwhile, the mechanical stimulation therapy combining

extracorporeal counterpulsation and local vibrating therapy are used for the

first time in the present invention, saving treatment time and cost.

The vibrating device drives a reciprocating motion of the connecting rod,

which in turn drives a reciprocating movement of the deformable touch plate,

and produces a vibration stimulation to muscle tissues; at the same time, the

control module controls the air injection and exhaust process of the airbag

according to the acquired data or the set data, and the airbag directly or

indirectly applies a pressure and vibrates muscle tissues to produce a

mechanical stimulation, so as to improve the microcirculation of muscle tissues

of lower limbs, and achieve the purpose of treating sarcopenia. The

mechanical stimulation kit for the treatment of sarcopenia further comprises an

ECG signal acquisition device that can regulate the vibrating device and adjust

the air injection and exhaust process of the airbag according to the ECG signal, so as to optimize the therapeutic regimen of sarcopenia. The push plate is arranged between the vibrating device and the connecting rod to facilitate the accurate and stable reciprocating motion of the deformable touch plate driven by the vibrating device.

The present invention also provides an adaptive capsule for the treatment

of sarcopenia, comprising a leg capsule with a double-layer structure, and the

"mechanical stimulation kit for the treatment of sarcopenia" as claimed herein,

wherein an inner layer of the leg capsule is made from a flexible material, an

outer layer thereof is made from a non-elastic material, the inner layer and the

outer layer form a closed cavity for accommodating at least two sets of

"mechanical stimulation kits for the treatment of sarcopenia", and the

deformable touch plate is attached to the inner layer of the leg capsule.

Further, each set of "mechanical stimulation kit for the treatment of

sarcopenia" comprises multiple airbags, and a gap between the "mechanical

stimulation kit for the treatment of sarcopenia" and the inner wall of the leg

capsule is densely filled with an airtight balloon.

Further, a barrier is arranged between the inner layer and the outer layer

of the leg capsule to separate a cavity of the leg capsule into a plurality of

mutually independent units, of which each unit is provided with a "mechanical

stimulation kit for the treatment of sarcopenia" respectively.

Specifically, the adaptive capsule for the treatment of sarcopenia

comprises a thigh capsule and a calf capsule, wherein the leg capsule of the

thigh capsule is provided with a barrier, which separates the cavity to form a

unit corresponding to the distribution of skeletal muscles of the human thighs; and the leg capsule of the calf capsule is provided with a barrier, which separates the cavity to form a unit corresponding to the distribution of skeletal muscles of human calves.

Specifically, the barrier comprises a horizontal barrier and a vertical barrier,

wherein the horizontal barrier divides the cavity of the leg capsule into four

layers, of which each layer is provided with four vertical barriers, and the

barrier divides the cavity into 16 mutually independent units.

The adaptive capsule for the treatment of sarcopenia according to the

present invention adopts the following principle: the leg capsule is sleeved on

the patient's leg and fixed, and the deformable touch plate with a pressure

sensor releases a gentle impact to the lower limb muscles at a certain rate.

The rebound rate and strength of the deformable touch plate are measured to

calculate the elasticity of muscle tissues. Based on the calculation results, the

air source system is controlled to inject air into the airbag. By this time, the

pressure sensor on the deformable touch plate continuously monitors the

contact surface pressure until a threshold value is determined, thus applying

an accurate pressure to the lower limb muscles. Depending on the elasticity of

skeletal muscles, the vibrating device generates a mechanical vibration at low

intensity and high frequency, and generates a vibration stimulation to muscle

tissues through the deformable touch plate; while the vibrating device

automatically adjusts the amplitude within a set range. The elasticity of skeletal

muscles increases at an increasing amplitude, and vice versa, which avoids a

damage to muscle tissues at excessive amplitude, and ensures sufficient

vibration stimulation to deep skeletal muscles.

The ECG signal acquisition device monitors the patient's ECG R-wave,

which can be used to predict the systole and diastole, and the air source

system sequentially inflates and deflates each airbag accordingly. During

diastole, airbags in each segment are inflated from far to near with a time

difference of approx. 50 ms, which increases diastolic pressure and circling

heart blood flow. During systole, the airbags are rapidly and synchronously

deflated, and the artery relaxes and receives blood from aorta after

decompression of lower limbs, thus achieving the purpose of improving

microcirculation of muscle tissues of the lower limbs.

The adaptive capsule for the treatment of sarcopenia has the following

advantages according to the present invention: firstly, the adaptive capsule

can be applied to the debilitated or bedridden elderly patients with severe

sarcopenia, without any special demands on position or active cooperation of

the patients; secondly, the microcirculation and neuromuscular stimulation are

combined to achieve the intervention treatment of sarcopenia; thirdly, the

adaptive capsule can adaptively adjusts the airbag size and air wave pressure

to an appropriate level according to the volume of lower limb musculature and

the elasticity of skeletal muscles. Specifically, the self-adaptation is reflected in

two aspects: on the one hand, the airbag can adaptively adjust the internal

pressure of the cavity of leg capsule at different positions by injecting air into

the airbag and applying a pressure on the legs, so as to ensure full contact

between the leg capsule and limbs, and accurately adjusting the pressure; on

the other hand, the vibration amplitude of the deformable touch plate can be

automatically adjusted in real time according to the elasticity of muscle tissues

in different parts of the patient.

The leg capsule is provided with a barrier to separate the cavity of leg

capsule into a plurality of mutually independent units, of which each unit is

provided with a "mechanical stimulation kit for the treatment of sarcopenia"

respectively. So, each unit can be sensed and controlled separately, which

ensures the complete fitting of the leg capsule to the limb tissues, facilitates

the precise control of the airbag pressure. The external counterpulsation

efficiency is improved, and different users can be given an individualized and

precise therapeutic regimen. The adaptive capsule comprises a thigh capsule

and a calf capsule, and can mechanically stimulate the muscles at the target

position according to the distribution of muscle tissues of thighs and calves,

which is conducive to ensuring the therapeutic effect.

DESCRIPTION OF THE INVENTION

The present invention will be further explained with reference to the

As shown in Fig. 1, the first subject of the present invention is a

mechanical stimulation kit for the treatment of sarcopenia, comprising a sleeve

1-1, a connecting rod 1-2, a vibrating device 1-3, a deformable touch plate 1-4,

a pressure sensor 1-5, a control module, an air source system 1-6, and an

airbag 1-7, wherein one end of the sleeve 1-1, i.e. the left end in Fig. 1, is

provided with an opening for accommodating the connecting rod 1-2, and the

opening is slightly larger than the diameter of the connecting rod 1-2, so that

the connecting rod 1-2 can move freely in the opening. The other end of the

sleeve 1-1, i.e. the right end in Fig. 1, is provided with the vibrating device 1-3

that is fixed relative to the sleeve 1-1, and one end of the connecting rod 1-2 is

connected to the vibrating device 1-3 that drives a reciprocating motion of the

connecting rod 1-2. The vibrating device 1-3 can be directly installed on the

sleeve 1-1. As shown in Fig. 1, the right side of the vibrating device 1-3 is an

installation end which is fixedly connected to the right end of the sleeve 1-1.

The connecting rod 1-2 can be directly connected to the vibrating device 1-3

that drives a reciprocating motion of the connecting rod 1-2 correspondingly.

Alternatively, as shown in Fig. 1, the sleeve 1-1 is internally provided with a

push plate 1-8 capable of sliding along the axial direction thereof, and the push

plate 1-8 and the sleeve 1-1 form a piston-cylinder relationship. The push plate

1-8 is arranged between the vibrating device 1-3 and the connecting rod 1-2.

The vibrating device 1-3 is arranged inside the sleeve 1-1, with the right side of

the vibrating device 1-3 being fixedly connected to the right end of the sleeve

1-1, and the left side of the vibrating device 1-3 being connected to the push

plate 1-8, and the left side of the push plate 1-8 is connected to the connecting

rod 1-2. The sleeve 1-1 is cylindrical, and the connecting rod 1-2 is preferably connected to the center of the push plate 1-8. At the same time, the opening at one end of the sleeve 1-1 is located at the center of the end face of the sleeve

1-1 to ensure the stability of the vibration direction of the connecting rod 1-2.

One end of the connecting rod 1-2 located outside the sleeve 1-1 is

connected to the deformable touch plate 1-4, and the side of the deformable

touch plate 1-4 facing away from the connecting rod 1-2 is provided with a

pressure sensor 1-5. The deformable touch plate 1-4 is mainly used for

vibrating muscle tissues and applying pressure thereto, and the pressure

sensor 1-5 is used for sensing and monitoring the pressure between the

deformable touch plate 1-4 and muscle tissues in real time. The deformable

touch plate 1-4 is made from a shape memory polymer (SMP) material, which

has the advantages of light weight, low price, large deformation, easy

programming and adjustable elastic modulus, and can be shaped by according

to the user's leg curve. The deformable touch plate ensures the pressure

transmission and closely fitting with the user's leg, thus crushing injury to the

leg. The pressure sensor 1-5 is electrically connected to the control module

that is connected to an air source system 1-6, the number of the airbag 1-7 is

one or more, and the air source system 1-6 is connected to the airbag 1-7 and

can inject air into the airbag 1-7 and exhaust air therefrom. The control module

can correspondingly control the air source system 1-6 according to the data

collected by the pressure sensor 1-5 or other settings, so as to adjust the air

pressure value of the airbag 1-7. The pressure sensor 1-5 is available, for

example, a Jingchengpu FlY button-type pull pressure sensor. The airbag 1-7

has certain elastic deformation and several to dozens of airbags 1-7 should be

provided. If a few, for example, several airbags 1-7 are provided, the volume of a single airbag 1-7 is relatively large after inflated. In contrast, if dozens of airbags 1-7 are provided, the volume of the airbag 1-7 is small after inflated.

In addition, the mechanical stimulation kit for the treatment of sarcopenia

comprises an ECG signal acquisition device that is electrically connected to

the control module. The ECG signal acquisition device is used to detect the

patient's ECG R-wave, based on which the systole and diastole are predicted

to guide and control the inflation and deflation of the airbag 1-7. During diastole,

air is injected into the airbag 1-7, which applies a pressure on muscles and

raises the diastolic pressure to increase the return blood flow. During systole,

the airbag 1-7 is deflated to weaken the pressure on muscles, and the arteries

are diastolic to accept blood from the aorta, thus improving the microcirculation

of the muscle tissues of the lower limbs.

The vibrating device 1-3 generates a vertical mechanical vibration at low

intensity and high frequency, which is transmitted to the deformable touch

plate 1-4 through the connecting root 1-2 and then acted on the human body.

The vibrating device 1-3 can be a vibration motor, wherein the vibration

frequency of the vibration motor is 30-45Hz and preferably 35-40 Hz, and the

amplitude thereof is 1.0-2.0 mm and preferably 1.1-1.5 mm. The amplitude of

the vibration motor is automatically adjusted within the set range according to

the measured elasticity of skeletal muscles. The vibration amplitude increases

with the increasing of elasticity of skeletal muscles, and vice versa. The

vibration motor vibrates the patient's muscle groups to stimulate the nerves for

therapeutic purposes.

The second subject of the present invention is an adaptive capsule for the treatment of sarcopenia, comprising a leg capsule 2, and the "mechanical stimulation kit for the treatment of sarcopenia". Referring to Fig. 2, the leg capsule 2 has a double-layer structure, comprising an inner layer 2-1 and an outer layer 2-2, wherein the inner layer 2-1 is made from a flexible material for direct contact with human body, for example, a SMP material, and the outer layer 2-2 is made from a non-elastic material, for example, an ABS plastic material, so as to apply a pressure on human muscle tissues. The middle part of the leg capsule 2 forms a circular space for accommodating the legs, and the leg capsule 2 can be directly cylindrical, or is vertically provided with zippers or fasteners, so that the leg capsule 2 can be conveniently put on and off later. The inner layer 2-1 and the outer layer 2-2 form a closed cavity for accommodating at least two sets of "mechanical stimulation kits for the treatment of sarcopenia", and the deformable touch plate 1-4 is attached to the inner layer 2-1 of the leg capsule 2.

The adaptive capsule for the treatment of sarcopenia comprises a

"mechanical stimulation kit for the treatment of sarcopenia", which should be

multiple sets, for example, 12 to 24 kits, depending on the distribution and

number of muscle groups in the thighs and calves of the human body. Each of

"mechanical stimulation kit for the treatment of sarcopenia" comprises several

or dozens of airbags 1-7. In order to accurately apply a pressure to muscle

tissues during inflation of the airbag 1-7, the gap between the "mechanical

stimulation kit for the treatment of sarcopenia" and the inner wall of the leg

capsule 2 should be filled after inflation of the airbag 1-7. Alternatively, the gap

between the "mechanical stimulation kit for the treatment of sarcopenia" and

the inner wall of the leg capsule 2 is densely filled with an airtight balloon 2-3.

The airtight balloon 2-3 is essentially a filling cushion, and can be spherical or

other shapes such as square and ellipsoid. The airtight balloon 2-3 can be

either a closed air balloon, i.e., a non-inflated and deflated balloon, or a closed

air balloon. The airtight balloon 2-3 works in conjunction with the airbag 1-7 to

apply pressure to the inner layer 2-1.

In order to make each set of "mechanical stimulation kit for the treatment

of sarcopenia" not interfere with each other, a barrier 2-4 is arranged between

the inner layer 2-1 and the outer layer 2-2 of the leg capsule 2 to separate a

cavity of the leg capsule 2 into a plurality of mutually independent units, and

one unit is a relatively independent chamber. Each unit is equipped with a

"mechanical stimulation kit for the treatment of sarcopenia". The barrier 2-4 is

distributed depending on the muscle groups in the legs. For example, the

adaptive capsule for the treatment of sarcopenia comprises a thigh capsule

and a calf capsule, wherein the leg capsule 2 of the thigh capsule is provided

with a barrier 2-4, which separates the cavity to form a unit corresponding to

the distribution of skeletal muscles of the human thigh, specifically, an anterior

thigh unit corresponding to the rectus femoris and vastus intermedius, a medial

thigh unit corresponding to the sartorius, vastus medialis and gracilis, a lateral

thigh unit corresponding to the vastus lateralis, and a posterior thigh unit

corresponding to the adductor magnus, adductor longus, biceps femoris,

semitendinosus and semimembranosus. The leg capsule 2 of the calf capsule

is provided with a barrier 2-4, which separates the cavity to form a unit

corresponding to the distribution of skeletal muscles of human calves,

specifically, an anterolateral calf unit corresponding to the tibialis anterior, a

lateral calf unit corresponding to the tibialis anterior, and an posterior calf unit corresponding to the gastrocnemius and soleus.

A specific arrangement of the barrier 2-4 is provided below. As shown in

Fig. 2, the barrier 2-4 comprises a horizontal barrier 2-4 and a vertical barrier

2-4, wherein the horizontal barrier 2-4 divides the cavity of the leg capsule 2

into four layers, of which each layer is provided with four vertical barriers 2-4,

and the barrier 2-4 divides the cavity into 16 mutually independent units; that is,

both the thigh capsule and the calf capsule comprises 16 mutually

independent units respectively, of which each unit is provided with a set of

"mechanical stimulation kit for the treatment of sarcopenia".
