Portable thyroid hormone tester

Abstract

The invention relates to a portable thyroid hormone tester, which comprises a shell, wherein a detection device is arranged in the shell; an acupuncture suction device is arranged at one end of the shell and communicates with the detection device in the shell; the detection device comprises a sample pad, a chromatographic film, a detection band, a quality control band and a colloidal gold bonding pad; and the sample pad, the colloidal gold bonding pad, the detection band, the chromatographic film and the quality control band are sequentially arranged far away from the acupuncture suction device. The portable thyroid hormone tester is capable of quickly and simply detecting PTH, and identifying parathyroid glands in situ, thus avoiding an intraoperative injury.

Description

technical field [0001] The invention belongs to the technical field of human body detection, in particular to a portable thyroid hormone measuring instrument. Background technique [0002] Thyroid cancer is a common tumor. In recent years, the incidence rate has been increasing year by year. According to my country’s national conditions, most hospitals still use subtotal or subtotal lobectomy as the main surgical method. Due to the small size of the parathyroid gland, it is closely related to the thyroid gland. The hypofunction caused by parathyroid injury in thyroid cancer surgery is the most common and one of the most serious complications after surgery. [0003] At present, the main measures to identify parathyroid glands during surgery are, first of all, to improve the awareness of the importance of parathyroid glands, make full preparations before surgery, and be familiar with the normal anatomical position, dedicated blood vessels, and abnormal anatomical structures.

Problems solved by technology

Secondly, it is a rapid pathological examination of the parathyroid glands during the operation, but part of the parathyroid glands needs to be removed, which is time-consuming and wastes part of the tissue

In addition, studies have shown that the thyroid gland and central lymph nodes can be visualized with nanocarbon suspension, but the parathyroid glands will not be visualized, but nanocarbon is more expensive, and in practical applications, nanocarbon has limited distinguishing effect, which will lead to local A large area of ​​tissue is black stained, and the parathyroid glands cannot be well identified

Since the parathyroid gland is an endocrine gland that can secrete parathyroid hormone (PTH), and the half-life of PTH is only 2-4 minutes, the concentration of PTH in the blood drops rapidly after parathyroidectomy. Detect the PTH concentration in the blood at different time periods (0.5h, 1h, 2h) to confirm whether the parathyroid glands have been removed, but this method requires coordination between the clinical department and the laboratory department, and takes a long time
