The present invention relates to a trapezius acupressure type massage device, and more particularly, to reduce muscle tension around the trapezius through acupressure action of repeatedly pressing and retreating the trapezius muscles located on both shoulder sides of the human body with air pressure centered on the cervical vertebrae. It relates to a trapezius acupressure type massage device that relieves and facilitates blood circulation.

Disc is one of the diseases that occur frequently due to lack of exercise and more people sitting and working in the same position for a long time. As the number increases, the number of people suffering from cervical vertebra disease, which is a part between the skull and the thoracic vertebrae, which is the backbone, among the parts constituting the spine is rapidly increasing.

On the other hand, the spine is composed of a vertebral body, which is the central body, a bow-shaped vertebra protruding from the back upwards, and several projections.孔) is formed, and the spine is maintained in the wrong posture for a long time, or spinal diseases occur due to muscle aging and strong external shocks. The cause can be found in lifestyle habits such as sitting, standing, or sleeping posture. In the case of children and adolescents in the growing stage, when there is an abnormality in the spine, the growth line is put under pressure and the secretion of growth hormone is not smooth. Failure to do so may lead to problems that inhibit growth promotion.

In particular, in recent years, as the usage time of smartphones increases regardless of gender and age, more and more people suffer from cervical vertebrae, which is the part between the skull and the thoracic vertebrae, which is a part of the spine, which constitutes the spine.

That is, the cervical vertebrae are generally referred to as the cervical vertebrae among the vertebrae of our body, and are composed of 7 vertebrae segments. The transverse process of each cervical vertebra has a hole through which the cervical artery passes, and veins and brachial plexus are located around it. , it can be said that it is an important part of the body that is connected to the trunk below and to the head above. These cervical vertebrae, like the thoracic and lumbar vertebrae, are greatly affected by the posture of the person, and various musculoskeletal diseases caused by this Have. As an example, the same cervical disc herniation as other vertebral discs may occur, sprains occur in the ligaments supporting the cervical vertebrae from the back, and the cervical vertebrae muscles are also stiff due to various causes, compressing the nerves, resulting in a headache. Various musculoskeletal disorders such as neck pain and shoulder pain can occur.

In general, for the treatment of back pain or shoulder pain, methods for treating or alleviating pathological conditions are widely practiced, such as physical therapy that strengthens muscles or stimulation of acupuncture points to facilitate blood circulation. In this case, it is desirable to correct the body shape correctly by relaxing the intervertebral discs that were pressed by making the gap between the vertebrae widen.

In other words, acupressure or massage is a kind of manual procedure that corrects the body's alterations to treat diseases and promote health by directly giving mechanical stimulation to the skin in a certain way using hands.手技施術), promotes the circulation of blood or lymph by acupressure and massage, increases the metabolism of the body, increases the nutrition of the tissue, excretes wastes, and strengthens the resistance. This tactile stimulation (觸壓刺戟) stimulates nerves and acts as an analgesic, so it promotes the recovery of paralyzed nerves and has the effect of correcting the modulation of internal functions.

However, since most of these acupressure/massage treatments cannot be performed by the person receiving the treatment alone, there is a problem that the effect is not constant because it is carried out depending on the power of the person as well as the inconvenience of receiving the type of help. In order to improve these problems, various types of acupressure/massage devices that can receive acupressure/massage on their own have been developed and used in the past. However, in the case of a vibration massager, it is a method of repeatedly hitting (tapping) a part of the body, so the acupressure effect is low as well as causing secondary pain due to the blow. In order to do this, the acupressure tool has to be pressed with a certain force on the body part, so it is not only inconvenient to use, but also has a problem that it is difficult to use continuously because of the force.

In addition, in the case of a pneumatic massager, the pressure is repeatedly applied to a part of the body by injecting and discharging air into and out of a cuff designed to cover a body part such as an arm, leg, or waist. It is difficult to expect acupressure effects such as stimulating acupuncture points, but also has the disadvantage of being cumbersome to use because it has to be worn on the arm, leg, or waist of the body. There is a treatment device equipped with a belt-shaped cuff that is provided to expand downward to exert traction, but it is also inconvenient to use because it must be worn on the neck or waist, and it is difficult to quickly respond to excessive pneumatic action, and sufficient traction effect can be obtained. There was a disadvantage that the treatment effect was low as there was no treatment.

In particular, as a prior art for improving the flow of cerebrospinal fluid by compressing the suboccipital muscle or its periphery while relaxing the cervical spine, a functional cervical pillow has been proposed through Patent Publication No. 10-1665115 (2016.10.12.). Specifically, it keeps the cervical vertebrae in a C-shape when lying down, and relieves the tension and pain of the neck muscles by applying acupressure on the cervical vertebrae 1. A technology related to a functional cervical pillow that allows It only maintains it, but it does not include the function of relaxing the cervical vertebrae and exercising the cervical vertebrae muscles, and it does not include a composition for compressing the ventricles along with the suboccipital muscle, so there is no function to relax the cervical spine and smooth the flow of cerebrospinal fluid. .

As another prior art, Korean Patent Publication No. 10-1077885 (October 31, 2011) relates to a myofascial relaxer for physical therapy, see. Specifically, the body is placed horizontally on the floor; Acupressure part of the occipital bone protruding from one side of the main body to support the occipital bone; The lower laryngeal support portion is formed to protrude higher than the laryngeal acupressure portion at the position in front of the occipital bone acupressure portion of the main body to support the lower larynx; and an upper thoracic vertebrae acupressure part protruding from the position in front of the lower occipital support part of the main body so as not to push the main body while supporting the back neck, and to press the upper thoracic vertebrae. Although the technique has been described, there is a problem that the therapeutic effect cannot be expected because it is only a structure that simply presses the occipital fascia and its surroundings using a number of protrusions.
