Problems solved by technology

For example, the patent No. CN201910220220.8 provides "A Special Arterial Blood Gas Collector for Children", including a syringe, an extension hose, and a needle body. With anticoagulant; it is easy to operate, enhances the success rate of children's arterial blood collection, and reduces the pain children suffer during the blood collection process; the disadvantage is that it is impossible to accurately judge whether it is arterial blood

Embodiment

[0026] Example: Figure 1 to Figure 13 It is a preferred embodiment of the present invention. In this embodiment, the grooved needle 101 adopts a No. 5 needle or a No. 6 needle with a length of 2.5 cm; the capacity of the syringe 302 is 3 ml, the outer diameter of the syringe 302 is 8 mm, and the inner diameter is 6 mm; the holder 2 The outer diameter is 2.5mm; the outer diameter of the box is 25cm, and the height is 50cm. The turntable 402 can accommodate ten blood storage bins 3 .

[0027] The slot needle 101 of the present invention has grooves on three sides, and each groove has a group of capacitors made of fixed capacitor plates 107 and floating capacitor plates 108. The gap is filled with solid glue; when the grooved needle 101 is inserted into the blood vessel, the floating capacitor plate 108 will be squeezed due to fluid dynamic pressure, causing the capacitance value to change. The current blood flow is arterial blood. The capacitive signal is first transmitted t...

Abstract

The invention provides an intelligent arterial blood collection device, which includes an intelligent needle, a holder, a blood storage bin, a storage box and the like. The whole machine is modularized, and the traditional blood drawing device is divided into three modules: smart needle, holder and blood storage compartment. At the same time, an additional storage box is added to facilitate batch carrying operations; smart needles use capacitors as sensing elements, According to the arterial blood pressure, feedback the capacitance value, and then control whether to draw blood; the blood storage chamber is a vacuum cavity, and the docking with the needle is realized by the holder; the smart needle and the blood storage chamber can be recycled.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an intelligent arterial blood collection device. Background technique [0002] Arterial blood is blood that flows in the arteries of the systemic circulation (large circulation) and in the pulmonary veins that return from the lungs to the left atrium in the pulmonary circulation (small circulation). Arterial blood contains more oxygen, less carbon dioxide and is bright red. The purpose of collecting arterial blood samples is mainly for blood gas analysis. Blood gas analysis is often used for the monitoring of respiratory failure and acid-base balance disorders, as well as the adjustment of mechanical ventilation parameters, curative effect analysis and prognosis judgment. For chronic respiratory diseases, it can provide accurate basis for doctors to determine treatment plans, adjust drugs, observe curative effects, etc. For example, the patent No. CN201910220220.8 provi...
