Embodiment Construction

[0029] The present invention is described in detail below in conjunction with accompanying drawing:

[0030] Such as Figure 1-2 As shown, the embodiment of the present invention provides an image-guided blood gas collection device. include:

[0031] 101, wrist fixing support.

[0032] Among them, the patient's wrist, the image acquisition module and the near-infrared light source module are fixed.

[0033] Specifically, the patient's wrist is fixed by the bracket to prevent the wrist from moving; the image acquisition module and the near-infrared light source module are fixed by the bracket to prevent the displacement of each module during the image acquisition, processing and display process. The image acquisition module is located above the wrist fixing bracket, and the infrared light source module is located below the wrist fixing bracket. After the wrist of the person to collect blood gas is fixed by the wrist fixing bracket, the radial side of the wrist 2 faces upward...

Abstract

The invention discloses an image guidance based blood gas acquisition device and method. The image guidance based blood gas acquisition device comprises a wrist fixing support, wherein an image acquisition module is fixed above the wrist fixing support, an infrared source module is fixed under the wrist fixing support, the image acquisition module transmits an acquired image to an image processing module, and the image processing module displays a processing result through a display module. The image guidance based blood gas acquisition device and method enable a medical worker to acquire blood gas according to the radial artery position information and guidance information on the display module and know needle insertion situation according to the image displayed in real time. Wrist images of a patient are acquired through three cameras, and acquired data are accurate.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an image-guided blood gas collection device and method. Background technique [0002] Blood gas analysis is a test method commonly used in medicine to judge whether there is an acid-base balance disorder in the body, as well as hypoxia and the degree of hypoxia. Arterial blood gas analysis can accurately reflect the respiratory function and metabolism of the body, diagnose respiratory failure and acid-base balance disorders, and guide oxygen therapy and mechanical ventilation. In blood gas analysis, whether the collection and preservation of blood samples are appropriate has a great influence on the measurement results. Arterial blood is used as the analysis sample for blood gas analysis, and the commonly used arteries for arterial blood collection are the femoral, brachial, and radial arteries. Because the radial artery is superficial, easy to touch, and easy to compre...
