Detailed Description

the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

it should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.

The invention is further described with reference to the following drawings and specific examples, which are not intended to be limiting.

The device for detecting the blood clot comprises an upper cover 1, a shell 2, a bottom cover 3, an ultrasonic generator 4, an ultrasonic receiver 5, an electrical module 6 and a plurality of indicator lamps 7;

the upper cover 1 covers the top of the shell 2, the bottom cover 3 covers the bottom of the shell 2, and the upper cover 1, the shell 2 and the bottom cover 3 form a shell of the device; the upper cover 1 is provided with a plurality of through holes slightly larger than the diameter of the test tube, the ultrasonic generator 4 and the ultrasonic receiver 5 are positioned in the shell 2, the test tube 8 can be inserted into the shell 2 through the through holes and is positioned between the transmitting end of the ultrasonic generator 4 and the receiving end of the ultrasonic receiver 5, the indicator lamps 7 are positioned on the upper cover 1, and the indicator lamps 7 correspond to the through holes one to one; the electric module 6 is mounted on the bottom cover 3;

An ultrasonic generator 4 for emitting ultrasonic waves toward the test tube 8;

the ultrasonic receiver 5 is used for receiving ultrasonic signals and then sending the ultrasonic signals to the electrical module 6;

The electrical module 6 is used for supplying power to other devices, obtaining blood clot information according to the ultrasonic signals and controlling the indication of the indicator light 7 according to the blood clot information; the method specifically comprises the following steps:

The electrical module 6 receives the ultrasonic signals to obtain an ultrasonic spectrogram, judges the size of the blood clot according to the amplitude of HITS in the ultrasonic spectrogram, and judges the number of the blood clot according to the number of HITS; the control indicator light 7 displays different colors when exceeding standard and not exceeding standard, when not exceeding standard, the indicator light 7 is green, and when exceeding standard, the indicator light 7 flickers yellow or is red.

in 8 insert devices of test tube to be equipped with blood, ultrasonic generator 4 sends the ultrasonic wave, passes test tube 8 to received by ultrasonic receiver 5, if the inside blood clot content of test tube exceeds standard, corresponding instruction is carried out to pilot lamp 7.

the principle of the invention is as follows:

The principle of ultrasonic detection of blood clots is that when ultrasonic waves are transmitted into a test tube filled with blood, because the blood clots and surrounding red blood cells and the like have different acoustic impedances, more ultrasonic waves are reflected on the blood clots/blood surface, and a distinguishable HITS is generated on a spectrogram; the size of HITS amplitude depends on the size of the blood clot, so that the size of the blood clot can be detected, and how much HITS quantity reflects how much of the blood clot.
