Problems solved by technology

[0005] The arterial blood gas needles currently used clinically are all imported from abroad, and the anticoagulant is placed in the syringe in the form of a ball or a sheet, which leads to some air remaining in the syringe
In addition, after the blood is drawn, the air can still pass from the needle to the ne

Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on the other component or t...

Abstract

An arterial blood gas needle relates to the medical instrument field, and comprises a syringe, a needle stand, a pull bar and a piston; the syringe is fixedly connected with the needle stand; the piston is fixedly connected with the end portion of the pull bar; the pull bar and the piston are movably sleeved in the syringe; the needle stand is provided with a through hole connected with the syringe; a sleeve rod is movably sleeved in the piston, and arranged in opposite with the through hole; the sleeve rod extends to one end in the syringe and is fixedly connected with a block; the cross section area of the block is bigger than that of the through hole, thus blocking the through hole; the pull bar is hollow; the other end of the sleeve rod extends outside the pull ar. The arterial blood gas needle can effectively isolate air so as to ensure the collected blood sample quality, thus effectively realizing blood anticoagulant purpose.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an arterial blood gas needle. Background technique [0002] Arterial blood gas analysis is of great significance in clinically guiding oxygen therapy to adjust various parameters of mechanical ventilation and correcting acid-base and electrolyte imbalances. The method of arterial blood sample collection has a very important impact on the results of blood gas analysis. The main influencing factors are the sampling process and whether it is isolated from the air when it is sent for inspection, and whether it is coagulated. [0003] There are two main technical requirements for arterial blood gas needles: 1. The sooner the arterial blood is exposed to the anticoagulant after entering the syringe, the better; 2. The arterial blood should be isolated from the air. [0004] There are three places where a syringe with a needle can retain air, namely inside the barrel; inside the needle...
