Description

Technical Field

[0001] This utility model relates to the field of medical image acquisition technology, and in particular to a Tibetan medicine urine image acquisition device. Background Technology

[0002] Tibetan medicine has a unique urine diagnosis method called the "Three-Times Nine-Diagnosis Method." This method diagnoses a patient's illness by observing the color, odor, foam, and sediment of urine. The "three times" in the Three-Times Nine-Diagnosis Method refer to observing the cooling process of urine in three stages: the hot period (hot urine period), the warm period (heat dissipation period), and the cool period (cool urine period). During the hot urine period, the color of the urine is mainly observed, while during the warm urine period, the cracks and thickness of the diagnosedigo surface, and the position and form of substances in the urine are observed to diagnose the condition.

[0003] This method is an intangible cultural heritage accumulated by the Tibetan people through long-term practice and has significant implications for the development of modern medical diagnosis. However, because its diagnostic method requires doctors to identify urine characteristics through their subjective senses, experience must be passed down orally, and a large amount of clinical experience is needed to make accurate diagnoses, making it difficult to widely disseminate, learn, and use. In particular, the conventional three-times-nine-diagnosis method involves observing the color of urine during the hot urine period and observing the cracks and thickness of the diaphragm, as well as the quantitative analysis of the position and morphology of substances in the urine during the lukewarm urine period. This is of great significance for the later development of Tibetan medicine's remote diagnosis and treatment. To achieve the above-mentioned quantitative identification, it is first necessary to acquire images of urine at different stages. Utility Model Content

[0004] Based on the above problems, the purpose of this utility model is to provide a Tibetan medicine urine image acquisition device that can control and adjust the temperature during urine image acquisition, filter out floating skin, floating matter, suspended matter and sediment in urine, and acquire urine images at different stages from multiple angles.

[0005] The technical solution adopted by this utility model to achieve its purpose is: a Tibetan medicine urine image acquisition device, including an outer urine bottle, an inner urine bottle, a DC motor, an image acquisition module, and a temperature control module, wherein:

[0006] The outer urine bottle is placed on a tray, which is rotatably mounted on top of a chassis. A DC motor is fixedly installed on the lower surface of the chassis, and the tray and the DC motor are connected by a transmission. The DC motor can drive the tray, the outer urine bottle, and the inner urine bottle to rotate.

At least three hooks are fixedly installed on the inner ring wall of the second bearing. There are at least three suspension ropes, with the top end of the ropes hanging on the hooks and the bottom end of the ropes fixedly connected to the top of the urine bottle.

[0017] Furthermore, the heating unit includes a heating control circuit and an electric heating device.

[0018] Furthermore, this device is also equipped with a main control module, which includes:

[0024] The heating unit in the temperature control module is also equipped with a second Bluetooth unit connected to the heating control circuit, which is used to communicate with the first Bluetooth unit in the main control module.

[0025] In this way, the heating unit can be centrally controlled through the main control module, the top-view and side-view cameras can be controlled to take pictures, and the DC motor can be controlled to drive the tray and urine bottle to rotate. This can improve the centralized control and automation capabilities of the device and increase work efficiency.
