Description

Technical Field

[0001] The invention relates to the technical field of cerebral hematoma positioning imaging, in particular to a portable cerebral hematoma positioning imaging device. Background Art

[0002] Cerebral hematoma is usually caused by craniocerebral trauma, which can lead to impaired consciousness and rapidly progress to brain herniation, thus endangering life. Early detection of life-threatening cerebral hematoma and preliminary characterization and positioning, providing reference for rescue personnel and rational selection of treatment methods are urgent issues to be addressed in out-of-hospital treatment sites such as disaster relief and battlefield treatment. Currently commonly used methods such as ultrasound and CT cannot achieve rapid injury assessment of cerebral hematoma victims out of hospital due to technical limitations, cost control, and large-scale equipment, and cannot provide sufficient diagnostic and treatment reference data for on-site emergency treatment.

[0003] In addition, in disaster emergency rescue and battlefield first aid, cerebral hematoma caused by exogenous trauma is a common secondary lesion of brain injury. After the blood vessels in the brain or between the brain tissue and the skull rupture, blood accumulates in the brain or between the brain and the skull, which compresses the brain tissue, increases intracranial pressure, and endangers the patient's life. The incidence of intracranial hematoma accounts for about 10% of closed craniocerebral injuries and 40% to 50% of severe craniocerebral injuries, and is higher in special scenarios. Intracranial hematoma can be roughly divided into epidural hematoma, subdural hematoma, and intracranial hematoma.

[0004] Rapid diagnosis and treatment of cerebral hematoma is of great significance to improving the survival rate of patients. Existing detection methods mainly include CT, ultrasound, MRI, etc. CT and MRI are not suitable for emergency rescue and battlefield first aid scenarios because of their large size and inability to be carried by one person. Ultrasound is limited by the scattering of sound waves by the skull and cannot effectively detect the entire brain.

[0005] The absorption rate and scattering characteristics of near-infrared light in cerebral hematoma and normal brain tissue are different. The higher the hemoglobin concentration, the higher the absorption rate of near-infrared light. By measuring the intensity of scattered light in a specific area, the degree of blood enrichment at that location can be determined. Combined with the pre-recorded basic detection data and trauma conditions, the positioning detection of cerebral hematoma can be achieved.

[0006] At present, the disclosed technologies include Inftrascanner 1000 / 2000 brain hematoma scanner, and publication number CN104434034B discloses "a handheld near-infrared brain hematoma detection device". However, the brain hematoma positioning imaging device in the prior art has only single-channel detection, and the detection target area is limited. Each detection is limited to a range of about 3 cm long and 1 cm wide. The accuracy of the detection target area is limited, and the noise interference of the skin, skull, etc. on the near-infrared light cannot be eliminated. It can only qualitatively detect whether the hematoma in the target area is negative or positive, and cannot provide accurate position reference for timely diagnosis and treatment such as puncture drainage, craniotomy and other emergency measures. In addition, the detection head and the host are integrated into one design, which cannot cope with all detection areas. It is inconvenient to detect when the patient's head cannot move to cooperate. Summary of the invention

[0007] The purpose of the present invention is to provide a portable cerebral hematoma positioning imaging device, which increases the portability and practicality of the device, adopts matrix multi-channel coverage, combination of target channel and background noise channel, graphical fitting of detection data, integrated detection unit group and flexible flexible detection unit combination technical means, to achieve rapid positioning and imaging of cerebral hematoma, improve the quality of triage, improve treatment efficiency and make disposal decisions.

[0037] Embodiment 1

[0038] Reference Figure 5 As shown, in this embodiment, if the patient's head is in a space that is easy to detect, the detection unit provided by the main body detection unit can be used for detection directly, and the ends of the three groups of detection units are placed in the target area of ​​the injured head, and are adjusted so that the ends of the detection units are in contact with the scalp tissue.

[0039] Embodiment 2

[0040] Reference Figure 5As shown, in this embodiment, if the patient's head is in a space that is not easy to detect, an external flexible detection unit 7 can be used. The patch of the external flexible detection unit 7 is placed on the target area of ​​the patient to be tested. After the enabling function is started, the second output light LED 74 emits a near-infrared light source, which is refracted and scattered by the tissue and then emitted. The signal is captured by the second photoelectric conversion IC chip 73 and sent to the signal processing mainboard. The built-in program of the mainboard can determine the hematoma condition of the area through which the light path passes based on the comparison operation of the incident light and the output light. The detection range covers a circular area, which is fitted into an image by the built-in software and displayed on the screen of the host 1 for reference in diagnosis and treatment.

[0042] (1) The use of a detachable external flexible detection unit increases the applicability and portability of the device, providing all-round coverage detection inspection when the application scenario is complex and the patient's head is inconvenient to move;

[0043] (2) The device adopts a matrix 3+2 multi-channel design, with a total of 5 groups and 10 channels. Each group contains two detection channels. One is a noise channel, which detects the background noise data of tissues such as the skull and skin. The other is a target signal data detection channel. In signal processing, the noise data of the noise channel is removed from the target signal data to make the target signal more accurate. Among them, 3 groups of channels are set in the integrated detection unit of the main body, evenly distributed around the circumference, which can cover all detection areas within a 70mm circumference and can cope with most cerebral hematoma scenarios.

[0044] (3) The device uses the different absorption rates and scattering characteristics of near-infrared light in cerebral hematoma and normal brain tissue. By judging the degree of blood enrichment at that location and combining it with the pre-recorded basic detection data and trauma situation, it can intuitively provide a relatively accurate location reference for emergency treatment plans.
