Abstract

The utility model relates to a medical position pad field discloses a position pad for thyroid gland CT inspection, the one end of position pad is diverged and is formed the recess, the top surface of position pad is the curved surface, follows the length direction of position pad divides into uphill section, flat section and downhill path section with its top surface, and wherein, the downhill path section is longer than the uphill section, lies when human back is crouched when the top surface of position pad, the recess blocks human cervical vertebra and compares with prior art with fixed neck, the beneficial effects of the utility model are that: when a patient lies on the position pad, the head and the neck of the patient can be in the hyperextension position, similar to the position of thyroid operation, and the thyroid and the clavicles are not in the same horizontal plane as much as possible due to the back pulling of the shoulders, so that the hardened wiring harness artifacts from the two clavicles are avoided.

Description

A position pad for thyroid gland CT inspection

Technical Field

The utility model relates to a medical position pad field especially relates to a position pad for thyroid gland CT inspection.

Background

At present, for examining thyroid gland alone, B ultrasonic has higher diagnostic value than CT and Magnetic Resonance (MRI), is more convenient and economic, has no radiation, and is the first choice. CT/MRI of the thyroid gland is not recommended for routine screening of the thyroid gland and assessment of thyroid nodules, but still has irreplaceable diagnostic value in some special cases. There are many contraindications for MRI examination or the image quality is caused by respiratory motion artifacts during cervical examination. The CT imaging speed is high, the influence of respiratory motion can be ignored, the size and the shape of the thyroid tumor can be clearly and intuitively displayed, the position relation between the tumor and surrounding tissues (such as trachea, esophagus, blood vessels, nerves and the like) can be more clearly understood after enhancement, and the invasion range of cancer can be determined, so that most patients can recommend CT examination before surgery by an operator, thereby providing scientific and intuitive basis for surgery and being also helpful for finding ectopic thyroid (such as thyroid after sternum).

However, when a neck CT examination is performed, the position of the clavicle and the thyroid is adjacent, hardening artifacts can occur due to the influence of nonlinear hardening artifacts and average volume, and when the artifacts are overlapped on the thyroid, the image quality and the CT value can be influenced, so that the diagnosis of thyroid related diseases is influenced. In the case of existing CT devices where the X-ray tube emits full-spectrum X-rays, this limitation is inherent and insurmountable, so that the hard beam artifacts are only reduced and not eliminated, and conventional pads are not satisfactory for use in neck (thyroid) CT examinations, and are generally used to assist patient immobilization or fall-down prevention.

SUMMERY OF THE UTILITY MODEL

The utility model overcomes the above insufficiency, and aims to provide a technical scheme which can solve the above problems.

The utility model provides a position pad for thyroid gland CT inspection, the one end of position pad is diverged from and is formed the recess, the top surface of position pad is the curved surface, follows the length direction that the position was filled up divides its top surface into upslope section, flat section and downhill path section, and wherein, the downhill path section is longer than the upslope section, lies when human back clings the top surface of position pad, the recess blocks human cervical vertebra in order to fix the neck.

Compared with the prior art, the beneficial effects of the utility model are that: when a patient lies on the position pad, the head and neck of the patient can be in the hyperextension position, similar to the position of a thyroid operation, and the thyroid and the clavicles are not on the same horizontal plane as much as possible by pulling the shoulders backwards, so that the hardened wiring harness artifacts from the two clavicles are avoided.

Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be understood that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 and 2, in an embodiment of the present invention, a body position pad for thyroid gland CT examination, one end of the body position pad 1 is diverged to form a groove 2, and an inner surface of the groove 2 is an included angle; the top surface of position pad 1 is the curved surface, follows the length direction of position pad 1 divides into the uphill section 11, flat section 12 and the downhill path section 13 that connect gradually with the surface of position pad 1, wherein, the surface of uphill section 11 risees gradually, and the surface 12 of flat section is flat, and the surface of downhill path section 13 reduces gradually, and downhill path section 13 is longer than uphill section 11, and it is worth mentioning that recess 2 sets up the uphill section 11 of position pad 1, body position pad 1 wholly is Y shape and both sides outwards protrusion promptly, and specific saying so, the side of position pad 1 also can divide into the syllogic structure that corresponds with uphill section, flat section and downhill path section along length direction, wherein, the interlude of position pad 1 side (correspond with flat section and lie in flat section both sides) and especially protrude, the material of position pad 1 is memory sponge or polyurethane foam.

As shown in figures 3 and 4, when in use, the body position pad 1 is placed in the middle of an examination bed, a human body sits on the back right in front, lies backwards on the body position pad 1, naturally lies flat (or simultaneously vertically bends the legs), is adjusted to be centered left and right, leans backwards, raises the chin, clamps the cervical vertebra in the groove 2, fixes the head and neck, enables the trachea and the sternum to be positioned at the same horizontal line as far as possible so as to be beneficial to fully exposing the thyroid gland, enables the two shoulders to do the back stretching action, visually observes that the thyroid gland and the two shoulders are not positioned at the same horizontal line, enables the neck to be horizontally parallel with the bed surface at the moment, fixes the horizontal positioning line of the examination at the middle crown line of the neck, is not too high or too low, and can reduce the radiation dose to the maximum extent and protect the thyroid gland.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
