Description

Quantitative trace blood and gas hemostix

Technical Field

The utility model relates to the technical field of blood samplers, in particular to a quantitative trace blood gas hemostix.

Background

The blood gas acid-base analysis is to detect the gas in blood, which is an important index reflecting the respiratory physiological function. Currently part of blood gas has been detected by combining electrolyte (NA, K, CL, CA) with part of biochemical project detection. The blood-qi specimen is mainly collected radial artery, forearm artery and femoral artery, because only arterial blood can correctly reflect the respiratory physiological function.

In addition, a trace blood gas hemostix with an automatic sealing device is mentioned in an application document with the publication number of CN213758255U, the blood hemostix is additionally provided with an automatic plugging device on the traditional trace blood gas hemostix and is matched with the traditional trace blood gas hemostix, when medical staff selects proper parts according to actual conditions of patients to puncture arteries at proper angles, blood can automatically enter the trace blood gas hemostix immediately when the medical staff performs arterial blood collection, the automatic plugging device is pushed into a taper joint passage port, the inner cavity of a cone-shaped passage is gradually enlarged and is in a state of more than or equal to 6 degrees, the diameter of the automatic plugging device is larger than the taper joint passage port, and the automatic plugging device can be clamped in the cone-shaped passage and is automatically closed when encountering blood; in the blood gas analysis process, when the blood gas analyzer absorbs the blood in the trace blood gas hemostix, under the action of the suction force of the blood gas analyzer, the automatic plugging device moves upwards, and the blood can be easily sucked into the blood gas analyzer for detection, so that the action of pulling out a sealing plug on a shell of the traditional trace blood gas hemostix in the market can be reduced, the workload of medical staff is reduced, humanized medical operation is realized, and the phenomenon that the concentration of oxygen and carbon dioxide in the blood changes and the internal arterial blood overflows due to long-time contact of the blood and the atmosphere after the sealing plug is pulled out by the trace blood gas hemostix can be effectively avoided, the detection time is shortened, and the accuracy of detection data is improved. In addition, after blood sampling is completed, the injection needle is firstly pricked on the rubber block and then is pulled out, so that an operator is prevented from being pricked, medical accidents are prevented, certain defects still exist, the optimization is needed, and the specific defects are as follows: when the existing hemostix is used for a disposable syringe, as the needle sheath is generally made into a cylinder shape, one end of the needle sheath is provided with an opening, and the needle is inserted from the opening, and as the opening is in clamping fit with the outer wall of the needle seat, the inner diameter of the opening is smaller, and people are not easy to align the opening when inserting the needle, so that the needle is inserted to deviate to cause the finger pricking people.

Therefore, it is important to design a quantitative trace blood and gas hemostix to improve the whole practicality by changing the technical defects.
