Description

Medical traction neck support

[0001] The utility model relates to a medical portable cervical vertebra tractor and a medical neck support.

Background technique

[0002] At present, the well-known medical portable cervical traction device and the medical cervical collar belong to two different products, and the medical portable cervical traction device is used for traction treatment of the cervical vertebra, mainly including a balloon retractor (for example, the patent application number 200610148837.6 airbag type) Cervical traction device), shoulder-loaded tractor (such as patent application number 91218692.5 shoulder fixed cervical traction device) two categories. The medical neck brace (such as the patent application No. 97214354.8 neck brace) is made of a polymer material and is mainly used for fixing and protecting the neck of the patient during use. The existing medical portable cervical traction device is convenient for the patient to carry with respect to the fixed cervical vertebra tractor. The airbag retractor generates upward traction by the airbag surrounding the neck. The shortcoming of the airbag retractor is that the traction force is average upward and backward, and the traction force mainly acts on the anterior chin. For the cervical vertebrae that needs to be pulled, the curve of the human body at the back of the neck is relatively straight, and the airbag material is soft. Sexuality, making it less effective for the upward traction of the neck, and the traction effect is not good. The shoulder-type tractor is fixed on the shoulders of the shoulder by the shoulder bracket, and the mechanical traction device is arranged on the two sides of the bracket, and the neck sleeve of the neck is lifted upward by the traction device on the bracket, thereby playing the role of the cervical vertebra. Relative to the airbag retractor, it has a large traction force on the cervical vertebra, but the disadvantage is that a traction bracket for hanging the neck sleeve needs to be fixed around the head. The bracket is not very convenient to carry due to the large volume, and the shoulder is used when the patient is used. A larger bracket on the top of the head is also not convenient for other activities, and the comfort of use is poor. The existing medical neck support only protects the patient's neck and protects the range of neck movement. Some products can adjust the height only as the size of the adjustment size. The disadvantage is that the lack of the head can be The adjustable support function of the active support is especially important for patients with cervical spine injuries. Summary of the invention

[0003] In order to overcome the shortcomings of the prior medical portable cervical traction device, the traction effect is not good or the volume is too large, and the existing medical neck support lacks an adjustable support function for the front and rear positions of the head, the utility model provides The utility model relates to a medical traction neck support, which can not only be used as a novel cervical-type cervical vertebra tractor, but has greater force on cervical traction than the existing airbag tractor, and is more compact and portable than a shoulder-mounted tractor. And can be used as a novel neck support with active (adjustable) support function for the front and back of the head, the traction neck support has two functions of cervical traction and neck support.

[0004] The technical solution adopted by the utility model to solve the technical problem is as follows: The four main components of the base, the lifter, the rocker arm and the pallet form a mutual coupling combination, and a combination is arranged around the neck before and after the lifting. Adjust the height of the support between the pallet and the base (traction) to support or fix the front and rear of the neck (head). Base shape It is made into an arc shape suitable for surrounding the neck, and a shaft hole for mounting the rocker arm is arranged on both sides; the rocker arm and the base are also formed into an arc shape at both ends, and a shaft which is movably engaged with the shaft hole of the base is arranged in the middle of the rocker arm. a curved support shaft for mounting the pallet is arranged at the top end of the curved shape; the pallet is designed to conform to (or close to) the contact portion of the human head, and a movable fit with the support shaft of the rocker arm is arranged near the central portion of the rocker Supporting hole; The lifter can be composed of a screw rod, a nut, a fixed shaft, etc., and the nut shape is made into a hand wheel that is convenient for hand rotation; the combination mode is: the pallet is mounted on the support shaft of the rocker arm through the support hole, and the rocker arm passes The two ends of the shaft are mounted on the two side shaft holes of the base. One end of the lifter is connected to the base and the other end is connected with the rocker arm, so that the four main components are coupled and assembled into a mutually rotatable (arc) combination around the neck. The two combinations are adjusted by the connecting devices on both sides to adjust the relative distance and the connection. The function of the base is to form a relatively fixed ring bracket around the neck. The function of the rocker arm is to support Positioning) The pallet is connected to the lifter, and the support (traction) force generated by the lifter is applied to the pallet through the support shaft on the rocker arm. The pallet is movably mounted through the support shaft on the rocker arm, and its function is to adjust the lifter. When the pallet rises to contact with the head, according to the physics principle, the pallet will automatically adjust the corresponding angle according to the curve shape of the contact surface of the human neck (head) according to the direction of the least resistance. When using, the lifter nut in the two combinations of the front and rear of the neck can be adjusted to adjust the angle (or height) between the rocker arm and the base through the screw, and the pallet on the rocker support shaft is moved up (down) to make the front The pallet in the combination bears against the chin jaw, and the pallet in the rear combination bears against the hindbrain to achieve support for the neck (head). At this time, the effect is equivalent to supporting the neck (head). The function of the "neck support" is a neck-type "cervical traction device" when the front and rear lifts are used to drive the rocker arm and the support plate on the support shaft to continue upward movement to achieve the traction required to pull the cervical vertebra.

[0005] The utility model has the beneficial effects that the utility model has the functions of the two kinds of cervical vertebra tractors and the neck support, and is used as a portable cervical vertebra tractor, and has the functions of separately adjusting the front and rear traction force of the neck and The function of the angle, and the advantage of small size and compact structure, is a novel cervical-type cervical vertebra tractor, which can be worn by patients in general daily activities; as a cervical collar, it has a front and rear position respectively. The upward support function of the adjustment, which is not known in the existing neck support, is another unique feature of the present invention compared with the existing products of the same type: the support acting on the front and rear of the neck (head) The force does not directly act on the pallet (in contact with the head), but acts on the pallet through a support shaft on the rocker arm. The advantage of this design is that the front and rear pallets can be based on the human neck (head). The contact surface curve automatically adjusts the corresponding angle, which minimizes the pressure on the surface area of the human body when the external force is applied, thereby High comfort of use of the product.
