The invention provides a coronary blood-flow volume acquiring method. The coronary blood-flow volume acquiring method comprises acquiring coronary image information to acquire coronary geometrical characteristic data; according to the coronary geometrical characteristic data, acquiring the total volume V of a coronary reference lumen, and calculating the blood-flow volume Q of an coronary openingaccording to a following formula, wherein, when the unit of Q is mm3 / s and that of V is mm3, K ranges between 5 and 9.5. The invention also provides a coronary blood-flow speed acquiring method. According to the coronary blood-flow volume and speed acquiring method, the coronary blood-flow volume and speed can be acquired through the coronary image information; compared with a method for estimating coronary blood-flow volume according to myocardium size in the prior art, the coronary blood-flow volume and speed acquiring method can provide more accurate boundary conditions for image-based hamodynamic calculation.

The invention discloses an intermediate-advanced stage cancer imaging detecting system and an intermediate-advanced stage cancer imaging detecting method based on the quantum superstring engine, mainly used for overcoming the defect that the traditional medical device can not efficiently, safely, rapidly and comprehensively detect the cancer cell spreading area of a cancer patient. The intermediate-advanced stage cancer imaging detecting system comprises a quantum light emission source, an optical splitter, a convex lens, a light filter group, a detection unit, an image processing unit and a display. The intermediate-advanced stage cancer imaging detecting method comprises the steps that orthogonal polarized photons generated by the quantum light emission source pass through the optical splitter, and then are transmitted in two paths; one path of the orthogonal polarized photons irradiates the body of the patient through the convex lens and light filters, penetrates through the body and then is received by a detector, and the other path of the orthogonal polarized photons directly passes through the light filters, and are received by another detector; the detection unit carries out combined measurement on the photons detected by the two detectors, and outputs a detection result to the image processing unit, the image processing unit draws a diffusion area imaging picture of cancer cells in the body of the patient, and the diffusion area imaging picture is displayed by the display. With the adoption of the intermediate-advanced stage cancer imaging detecting system and the intermediate-advanced stage cancer imaging detecting method, the diffusion area imaging picture of the cancer cells can be obtained, and thus a basis is provided for the treatment and research on the cancer patient.

Heating, shaping and quenching operation of a plate spring can be automatically implemented, various working procedures are automatically and continuously executed, linage is compact, and the product production efficiency and the output quality are greatly improved.

The invention discloses an ear-hanging device equipped by an electric power regulation and control attendant, comprising an ear-hanging main body which is of a cavity structure; one end of the ear hanging device is provided with a hook body bending toward the ear-hanging main body; the other end of the ear-hanging main body is provided with a battery chamber; an indication lamp panel is positioned on the upper part of the end surface, which is on the contrary to one end surface of the ear-hanging main body corresponding to the hook body; the middle part of the end surface is provided with a switch panel; the free end of the hook is provided with a buzzer; an inclination angle sensor and a programming controller which are mutually connected are arranged inside the cavity of the ear-hearing main body; and the inclination angle sensor is provided with a normally open contact switch which is connected to the programming controller. The ear-hanging device disclosed by the invention wakes up the regulation and control attendant who is about to go into a deep sleep state through deflection sensing of the inclination angle sensor and the programming controller controlling the working state of the buzzer, and enables the attendant to focus and finish the detection work.

The invention discloses a sampling head, a sampling system, a mass spectrometer imaging device and a sampling method. The sampling head includes: a sampling body, one of two opposite sides of the sampling body is provided with a tenon, and the other side is opposite to a A mortise with a size matching the mortise is provided; a sampling cavity, the sampling cavity is arranged on the first end face of the sampling body, and the sampling cavity forms a sampling area with the sampled surface; it is used for injecting and extracting The first flow channel for reagents; the second flow channel for injecting air and the third flow channel for exporting sample droplets. Since the sampling head in the present invention is directly in contact with the surface to be sampled, sampling can be realized without being separated from the body, and the method of liquid droplet extraction will not cause trauma to the surface to be sampled, and the sampling cavity is close to the surface to be sampled, which improves the quality of the sampling liquid. Drop concentration, reducing the possibility of loss of key compound information, thereby improving sampling quality.
