Problems solved by technology

The current microwave-based stroke type identification methods mainly focus on animal experiments, and there is still a lack of multi-channel microwave detection antenna array hoods suitable for clinical detection application scenarios.
In addition, the current detection system host, signal generation processing module and multiplexing switch are usually located in different independent components, making the host not compact and not portable

Embodiment 1

[0040] see Figure 1 to Figure 2 , a portable microwave detection system for pre-hospital diagnosis of clinical stroke types, mainly including an antenna array head cover 1 and a detection host 2.

[0041] The antenna array hood 1 includes a semicircle I101 , a semicircle II102 , a hinge 103 and several microwave radiation antenna units 104 .

[0042] One end of the semi-circular ring I101 and one end of the semi-circular ring II102 are connected by a hinge 103 .

[0043] The length of the hinge 103 is adjustable, thereby making the circumference of the antenna array head cover 1 adjustable.

[0044] The angle between the two arc-shaped parts can be adjusted through the hinge, so as to adapt to users with different head circumferences.

[0045] The semi-circular ring I101, the semi-circular ring II102 and the hinge 103 form an unclosed circular ring.

[0046] In order to avoid affecting the microwave detection results, the semi-circular ring I101, semi-circular ring II102 a...

Embodiment 2

[0066] see Figure 3 to Figure 7 , a method of using a portable microwave detection system for prehospital diagnosis of clinical stroke types, mainly comprising the following steps:

[0067] 1) Before testing the user, adjust the angle between the two symmetrical arc parts through the hinge, so as to accurately place the antenna array hood to a suitable position without affecting the user, and then adjust the two angles after placing it. Angle the curved parts and tighten the hinges to begin the formal inspection.

[0068] 2) During detection, the user wears the antenna array headgear 1 on his head.

[0069] 3) The PXI chassis controls the multiplexing switches 201 to be sequentially turned on, so that the signal transmitting device sends a signal source to the microwave radiation antenna unit 104 connected to the conducting multiplexing switch, and then the microwave radiation antenna unit 104 sends microwaves. The inner cavity of the antenna array hood 1 forms a microwave ...

Abstract

The invention discloses a portable microwave detection system for pre-hospital diagnosis of a clinical stroke type, and mainly comprises an antenna array hood and a detection host. The invention proposes to establish a multi-channel microwave detection antenna array hood for clinical detection application scenarios, through the targeted design, the detection can be carried out without moving a patient under test, while the multi-channel microwave detection characteristics are retained. For the portability problem of the host, a PXI chassis, a multiplexing switch and a signal generation processing module are integrated through a PXI protocol, so that the detection system host is composed of only one independent module, and integration and portability are realized.

Description

technical field [0001] The invention relates to the technical field of biomedical medical equipment, in particular to a portable microwave detection system for pre-hospital diagnosis of clinical stroke types. Background technique [0002] Stroke is divided into hemorrhagic stroke and ischemic stroke, but the clinical treatment methods of the two types of stroke are mutually exclusive, making the diagnosis of stroke type before treatment essential. Especially for ischemic stroke, according to European clinical guidelines, 4.5 hours after stroke is the golden time to receive thrombolytic therapy, and the earlier the better. However, due to transportation and other reasons, a large number of patients have missed the golden period of thrombolysis when they arrive at the hospital, so that even less than 10% of ischemic stroke patients receive thrombolysis. Therefore, it is of great significance to develop a portable, fast, and easy-to-operate instrument that can diagnose stroke ...
