Blood collection device used during invasive artery monitoring

Abstract

The invention discloses a blood collection device used during invasive artery monitoring. The blood collection device comprises an arterial duct, a pressure connection tube, a pressure sensor, a continuous washing system and an electronic monitor, wherein the pressure connection tube is filled with liquid and provided with a switch. The blood collection device is characterized in that the pressure connection tube is provided with a blood collection plug, a three-way plug valve and an injection syringe, the blood collection plug is arranged on the part, on the root of a palm of a patient, of the pressure connection tube, the three-way plug valve is arranged between the blood collection plug and the injection syringe, and the injection syringe and the pressure connection tube are formed at a time. During blood collection, the injection syringe sucks the liquid in the pressure connection tube, blood is sucked to the position of the blood collection plug, a blood taking needle punctures the blood collection plug and the blood is collected; after blood collection is finished, the liquid sucked out by the injection syringe is injected into the pressure connection tube, waste of the blood of the human body of avoided, and pulsating pressure produced during injection of the injection syringe can reduce the blood vessel blocking probability; meanwhile, no bloodstain is formed on the blood collection position, and therefore the blood infection probability of the patient is reduced; in addition, blood collection steps are simplified and the quantity of consumables is reduced.

Description

technical field [0001] The invention relates to a blood collection device, in particular to a blood collection device for invasive arterial blood pressure monitoring, and belongs to the technical field of medical equipment. Background technique [0002] Invasive arterial blood pressure monitoring is a method of directly measuring intra-arterial blood pressure by inserting an arterial catheter into the artery. It is suitable for intraoperative and postoperative monitoring of patients with shock, severe illness, severe peripheral vasoconstriction, major surgery or life-threatening surgery. , Monitoring of other high-risk patients. Invasive arterial blood pressure monitoring has the following advantages: 1) Direct arterial pressure monitoring is a continuous dynamic change process, not affected by artificial pressure, cuff width and tightness, accurate and reliable, and can be taken at any time; 2) It can be changed according to arterial waveform 3) The sudden change of arteri...

Problems solved by technology

With this method, although the third blood collection needle C is used to clean the waste blood of the three-way cock D, there will still be residual blood stains at the three-way cock D, which may cause blood infection and waste of blood; , its operation process is complicated, and it also increases the consumables
