Problems solved by technology

[0006] At present, after the nurses use the new arterial blood gas needle to collect blood from the patient's artery, they pull out the needle of the new arterial blood gas needle and insert the needle into the rubber stopper or cork or the gel sleeve, which often causes air to flow from the patient's blood. The needle enters the syringe filled with blood, which causes the oxygen partial pressure of the blood sample to increase and the carbon dioxide to decrease, resulting in the inability to obtain accurate results from blood analysis, and thus unable to make accurate judgments on patients and clinics

Embodiment Construction

[0024] Such as figure 1 As shown, a novel arterial blood gas needle includes a syringe 1, a needle base 3 integrally connected with the syringe, and a needle 4 detachably connected to the needle base. There is a piston 2 inside the syringe. The basic structure of blood gas needle blood collection.

[0025] Wherein, a circular baffle 5 is arranged inside the needle base, and the circular baffle 5 fits the radially inner section of the needle base 3, and a knob 6 is arranged on it, and the knob 6 is rotatably connected to the needle base 3, and is connected to the needle base 3 from the circular baffle. The place where the plate 5 is located extends to the outside of the needle hub 3 and is used to control the left and right rotation of the circular baffle 5 . This setting is helpful for the nursing staff to select the connection state between the needle base 3 and the needle head 4 of the novel arterial blood gas needle according to the needs. When blood collection is required...

Abstract

The invention belongs to the technical field of medical devices and specifically discloses a novel arterial blood gas needle. The novel arterial blood gas needle of the present invention comprises a needle barrel, a needle seat integrally connected with the needle barrel, and a needle head detachably connected with the needle seat. The needle barrel has a piston inside; A baffle, the diameter of the circular baffle matches the radially inner section of the needle base, and a knob is arranged on it, and the knob is rotatably connected to the needle base, and from where the circular baffle is located, extending to the outside of the needle seat. The novel arterial blood gas needle is not only simple in structure and easy to operate, but also can effectively avoid contact between blood samples and air, thereby effectively improving the accuracy of arterial blood gas analysis.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of medical appliances, in particular to a novel arterial blood gas needle. [0003] 【Background technique】 [0004] Arterial blood gas analysis is one of the important monitoring measures for acute, severe, and critical patients. It can objectively reflect the nature and degree of respiratory failure, and is a reliable method for judging whether a patient has hypoxia and carbon dioxide retention. It is of great significance to clinically guide oxygen therapy to adjust various parameters of mechanical ventilation and correct acid-base and electrolyte imbalances. [0005] 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 and whether it is coagulated when it is sent for inspection. That is, the technical requirements of the new arterial blood gas n...
