Description

A driver's spine health care device installed on a car seat

technical field

The invention relates to a spine health care device, in particular to a spine health care device which can be installed in a car, and belongs to the technical fields of medical care equipment and cars.

Background technique

With the improvement of people's living standards, the phenomenon of unbalanced diet, excess and insufficient exercise generally exists, and there are more people who are overweight or even obese. The overweight body puts too much burden on the spine, coupled with sedentary, desk and other bad habits, resulting in a large number of patients with spinal diseases, especially drivers and desk workers. The spine bears the entire weight of the upper body of the human body. When the vertebral joints are unevenly stressed or move, they need to be pulled by ligaments and muscles to maintain balance, and it will also cause excessive compression on the intervertebral disc, which will cause the fibrous ring to deform, protrude, and even rupture , Prolapsed nucleus pulposus. Muscle strain and intervertebral disc herniation often occur in the cervical and lumbar spine of the human body. When driving or sitting for a long time, in order to maintain the balance of force on various parts of the body, the muscles of the lower back need to maintain a tense state of contraction for a long time, and you will feel back pain. Cars have generally entered people's daily lives, and the pain of the cervical spine and lumbar spine has had a greater impact on drivers.

For health care and spinal disease treatment, people have improved car seats, optimized the structure and performance of cushions and backrests, and added electric adjustment, heating and multiple massage health care functions. The invention patent with the application number 201410472476.5 proposes a car seat lumbar support device for relieving driving fatigue. It is equipped with a lumbar support airbag combination and a lifting mechanism, which can adjust the upper and lower positions and support strength, and can reduce driver fatigue. The car seat lumbar support device can provide support for the driver's waist, and can relieve some muscle tension of the lower back muscles, but the support of the upper body weight of the human body is still concentrated on the lumbar spine, and the degree of reduction of lumbar spine compression is small. The invention patent with the application number 201410527860.0 proposes a driver fatigue-proof safety chair with an inflatable neck fork part, flip the inflatable neck fork to the required angle, inflate the neck fork, put the neck into the neck fork and Put on the belt cover and hold your head up naturally. The inflatable neck fork part can effectively relieve the compression of the head on the cervical spine; under severe bumps, vibrations and impacts, the human body moves relative to the seat, and the weight of the human body will directly act on the cervical spine in an instant. Excessive force may easily cause cervical spine injury .

Multiple spinal traction therapy and massage health care devices have occurred at present. Due to the constant bumps, vibrations and impacts of the driving car, the risk of human injury is increased. The cervical and lumbar traction therapy devices currently used in homes and hospitals cannot be directly installed on the car for use. The invention patent with the application number 201310136396.8 proposes a device for preventing and treating lumbar and cervical disc herniation, including a seat, a cervical spine correction airbag, a lumbar spine correction airbag, a mandibular adhesive belt, a chest adhesive belt and a waist adhesive belt . By bonding the belt, the mandible, chest and waist of the person are fastened to the chair, which plays a good role in fixing the cervical and lumbar vertebrae of the human body, and at the same time restricts the movement of the person, especially the movement of the head. If installed on the car seat, it will affect the driver's normal driving. In addition, in the sitting position of the driver, the waist adhesive belt will squeeze the abdomen, which has a strong sense of binding and is likely to cause discomfort, especially for those with belly fat and pregnant women. The utility model patent with the application number 201220723093.7 proposes a multifunctional vehicle traction belt, which includes a traction belt, a fixing belt and a multifunctional air pillow, which can be fixed on the seat of a vehicle and generate upward traction force under the weight of the body. The length of the traction belt is adjusted through the snap ring, which requires the cooperation of both hands, which is difficult for the driver during driving, and is more suitable for the occupant to use. The traction belt passes through the armpit and is fixed on the seat, which can reduce the partial pressure of the human body on the lumbar spine. Since the traction belt is made of flexible fabric, it has a certain degree of elasticity, and the force is relatively concentrated. When it is violently bumped, vibrated and impacted, it is easy to cause local skin discomfort, redness, and even abrasions or ruptures. The invention patent with the application number 201710387301.8 proposes a driver's body safety and health care belt, which can be adjusted by a motor-driven lifting device, and the tightness adjustment is convenient; there is also the problem of excessive local force, which may easily cause discomfort and skin damage. The invention patent with application number 201410063304.2 proposes a driver-specific intervertebral disc force reducer, which includes a support device and its fixing belt; the support device includes a pair of support tubes and a support rod threaded therewith; the support The upper end of the tube is fixed with a rubber support that is supported under the armpit. The weight of the human body is transferred to the seat through the rubber support, support tube and support rod, which can reduce the burden on the spine. Although the rubber support has a certain buffering effect, but the rigid support, the underarm is under a large force, and it is easy to cause injury under severe bumps, vibrations and impacts. In order to solve the problems of local discomfort and skin damage, the utility model patent with application number 201720338849.9 proposes a vehicle-mounted safety clothing, which includes a clothing cover and a safety frame. The clothes cover is connected with a safety frame rigidly fixed on the car seat through a safety belt; a plurality of safety airbags arranged in parallel are sewn inside the clothes cover; the rear side of the safety airbag is provided with heat-insulating paint. The vehicle-mounted safety clothing can perfectly fit the upper body of the human body and protect the spine, but it has a large contact area with the upper body of the human body, and the heat insulation performance of the airbag has poor air permeability, which is easy to cause discomfort, especially in hot summer. In addition, clothes such as shirts and vests are made of fiber fabrics, which are flexible and easy to deform when subjected to tension, which will cause greater pressure on the local protruding parts of the upper body of the human body, uneven force, and easily cause a sense of binding and discomfort. The protruding parts of the front of the upper body of the human body include the pectoralis major, breast and raised abdomen; compression of the protruding parts can cause discomfort and soreness, and in severe cases, local congestion and swelling can easily be caused. Bones are the hard organs of the body that support and protect the body. Moderate pressure on bones can be dispersed, muscle tension is relieved, and the body feels comfortable, but excessive impact can cause fractures and organ injuries. For example, when carrying objects on the shoulder, the pressure acts on the bones of the shoulder, while carrying heavy objects requires the muscles and ligaments of the arm to resist gravity, so shoulder-supporting objects feel more comfortable than carrying objects of the same weight. When one shoulder is stressed, some muscles need to be contracted to maintain body balance. Therefore, a shoulder bag of the same weight is not as comfortable as a backpack.

In order to alleviate the pain of patients with spondylosis, relieve driving fatigue and protect the spine, under the premise of ensuring safety, it is necessary to further improve the existing driver's spine care device.
