Description

Upper limb auxiliary supporting device for CT examination

Technical Field

The utility model belongs to the technical field of supplementary medical instrument, especially, relate to a CT inspection is with supplementary strutting arrangement of upper limb.

Background

As is well known, CT examinations are widely used in medical services. At present, CT scanning beds are all provided with head frames, so that head scanning is very convenient; when the examination of each part of the body below the neck is carried out, both hands need to be lifted from both sides of the body to the top, but the existing CT scanning bed has no racks for supporting both hands, the both hands of the examined person are in a suspended state when the examined person lifts, the lifted person possibly holds most of the examined person in a short time, and most of the examined persons are difficult to support and the both hands are in a suspended fixed state for a long time when the examined person carries out the enhanced examination because of more examined parts. If the examinee moves both hands, it is easy to interfere with the scanning, and the scanning progress and the scanning quality are affected. Especially when the enhanced examination or blood vessel imaging of the part below the chest and the abdomen is carried out, the multi-period enhancement is often needed, the time is relatively too long, and if the suspended hands cannot keep a constant state, the scanning quality is inevitably influenced. The most clinically used non-ionic contrast medium for enhancing CT examination is a non-ionic contrast medium with a high concentration, and the flow rate is generally required to be 2.5-4.5ml/s when a high-pressure syringe is used for injection, so that a proper blood vessel is selected according to the difference of examined parts and the requirement of liquid medicine flow when the blood vessel is selected. Generally, a blood vessel with thicker and straight upper limb and good elasticity is selected, the median cubital vein is selected as the first choice, and a proper vein part is selected to be deeply buried and retained in the median cubital vein.

In actual work, for many patients with advanced age, weak body or unconsciousness, the two hands of the patients are difficult to keep a constant state for a long time, and an indwelling needle needs to be deeply buried in the elbow joint vein during the enhancement examination, if the elbow joint can not keep a corresponding straight state for a corresponding time and is bent, a light person can deform and bend the indwelling needle, the normal enhancement function can not be performed, and a serious person can puncture the blood vessel, so that the contrast agent can be leaked to cause a series of adverse effects.

For example, the radiology department in our hospital faces the national tumor patients, including the patients before and after operation and chemotherapy, in order to assist the diagnosis of the patients, the patients need to carry out the enhanced CT examination, and the increased CT is to carry out the imaging technology by intravenous injection of contrast medium containing iodine, thereby improving the display rate of the lesion. The method is characterized in that upper limb veins such as elbow middle and the like are added to a CT vein, the upper limb veins enter a CT room for examination after the vein is retained, for example, the chest examination of a breast cancer patient is taken as an example, the left side operation of the patient can only select the right elbow middle or lower limb vein, the patient lies on a CT examination bed and lifts up with both hands, an iodine-containing contrast medium is injected through a retaining needle, the iodine-containing contrast medium belongs to a hypertonic solution, about 120 plus 150ml of contrast medium (the dosage is calculated according to kilogram body weight) needs to be injected under a high-pressure injector during the reinforced CT according to the requirements in the operation specification, and if the upper limb of the patient is not straightened, the phenomenon that the injected medicine is not smooth and even the medicine is extravasated can be caused.

In addition, some people need to inspect both hands, blood vessel imaging of both upper limbs and the like, the fixation of the hands is more important, and if the hands slightly move, the whole inspection fails, so that the use of the upper limb bracket is particularly important for supporting and limiting the suspended both hands. However, the existing upper limb bracket has the disadvantages of complex structure, not simple and convenient operation, high production cost and poor practicability.

Therefore, the upper limb auxiliary supporting device for CT examination is suitable for patients of any body shapes, and can fix and support the arms and elbows of the patients in a comfortable manner for CT scanning to be smoothly carried out and the accuracy of scanned data is improved.
