Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of binaural variable temperature hot and cold tests, in particular to a temperature-controlled binaural variable temperature hot and cold test water perfusion device. Background Art
[0002] Among the many tests in the electronystagmography or nystagmography test, the caloric test is the only one that can assess the function of unilateral semicircular canal and is also one of the most important tests in vestibular function testing.
[0003] At present, the hot and cold air perfusion method is mainly used in clinical practice. Although hot and cold air perfusion has the advantage of easy operation, the actual stimulation intensity received by both ears during the operation is easily affected by various factors, such as temperature, the subject's alert state, ear anatomical variation, abnormal body temperature, etc., which will have a certain impact on the test results. When the total hot and cold response of one ear is less than 12° / s, that is, RC+RW of the right side is less than 12° / s, it is considered that the response of one side is low. During the clinical testing process, some subjects will be affected by the environment or other factors, resulting in low results, and diagnosed with mild or weakened semicircular canals, which affects the patient's treatment plan and causes a greater economic burden.
[0004] When there is no response or low response to the binaural variable temperature hot and cold test gas perfusion, in order to provide a better basis for diagnosis, it is necessary to perform the hot and cold test water perfusion test. At present, homemade devices are mostly used in clinical practice, and water temperature is measured with a thermometer. The water temperature and flow rate are difficult to control, and it is difficult to carry out in clinical practice. Utility Model Content

DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0022] The utility model provides a technical solution: a temperature-controlled binaural variable temperature hot and cold test water perfusion device. In this embodiment, Figure 1 and Figure 3 As shown, an interlayer 9 is arranged in the box body 1, wherein the box body 1 is a rectangular white transparent hard plastic box, and a two-color temperature control element 2 is installed in the interlayer 9. Through the setting of the temperature control element, the disadvantage that the homemade device cannot automatically control the temperature is solved, so that the clinical operation is convenient and accurate. A rubber tube 4 is installed at the center of the lower side of the box body 1, and a flow rate control element 8 is arranged on the pipeline of the rubber tube 4 close to the box body 1. A joint 6 is installed at the end of the rubber tube 4, and a round blunt-headed hose 5 is threadedly connected to the joint 6. The round blunt-headed hose 5 is threadedly connected to the rubber tube 4. Compared with the traditional hard tube, it is not easy to cause damage to the patient's external auditory canal. This tube is a replaceable component. One hose 5 is only used by one patient, which can effectively avoid the occurrence of medical-induced infection.
[0023] like Figure 1-3 As shown, the two-color temperature control element 2 includes a heating wire 206 arranged in the interlayer 9, a battery compartment 205 is installed at the bottom of the box body 1, and the battery compartment 205 is electrically connected to the heating wire 206. A temperature sensor 204 is installed inside the box body 1, and a controller 203 is installed on the outside of the box body 1. A red temperature control lamp 201 is installed on the box body 1 below the controller 203, and a green temperature control lamp 202 is installed on the box body 1 on one side of the red temperature control lamp 201. The battery compartment 205 is electrically connected to the heating wire 206, the temperature sensor 204, the controller 203, the red temperature control lamp 201 and the green temperature control lamp 202 respectively.

During specific use, when the water temperature in the box body 1 is 30℃±0.5℃, the temperature sensor 204 will transmit the signal to the controller 203, and energize the green temperature control light 202, so that the green temperature control light 202 displays green. When the water temperature in the box body 1 is 44℃±0.5℃, the temperature sensor 204 will transmit the signal at this time to the controller 203, and energize the red temperature control light 201, so that the red temperature control light 201 displays red.
[0024] like Figure 1 As shown, a strap 7 is provided on the rubber tube 4, one side of the strap 7 is provided with a Velcro surface, and the other side of the strap 7 is provided with a Velcro hook surface.
