Description
Technical Field
The utility model relates to a medical instrument, it is specific, relate to a trace amount blood gas hemostix with self sealing device.
Background
The blood gas acid-base analysis is used for detecting the gas in the blood and is an important index for reflecting the physiological function of respiration. At present, part of blood gas is detected by combining electrolytes (NA, K, CL and CA) and part of biochemical project detection. The collection of radial artery, forearm artery and femoral artery is the main aspect of blood-qi samples, because only arterial blood can correctly reflect the physiological function of respiration.
At present, there are two main ways for collecting blood gas samples in China: disposable syringes and blood gas sampling devices (blood gas needles). Wherein the following problems are easy to occur when a disposable syringe is used for collecting the blood gas sample:
1. difficulty level: when the injector collects arterial blood, an operator operates with two hands to determine whether the arterial blood vessel is punctured by experience, when the operator punctures the arterial blood vessel by experience, the other hand starts to draw blood, if the operator is not operated properly, the arterial blood vessel is easy to puncture or the venous blood is easy to be drawn, and the collection of old people and children is very difficult.
2. Patient privacy: the syringe has large blood collection amount (1.5-2ml), mainly including femoral artery (femoral root artery tube).
3. Pain sensation: the pain is mainly determined by the thickness of the needle and the blood sampling time, the syringe needle is generally selected to be between 0.65 and 0.8, and the blood sampling time is about 10 to 15 seconds when the blood sampling amount is 1.5 to 2 ml.
4. Sample variation amount: the following factors mainly influence the specimen result;
A. the blood specimen should be isolated from the air, and the air isolation of the injector is better.
B. The temperature of the blood sample and the influence of the temperature on the sample are large, the standing time of the injector sample is not suitable to exceed 15 minutes under normal conditions, because the injector can not rapidly cool the blood sample, so that blood cells, particularly white blood cells and reticulocytes continue to metabolize to generate acid metabolites such as lactic acid and the like, and the PH and BE are reduced.
C. Blood and qi specimen storage material. The injector is a plastic product, and the plastic product has obvious oxygen consumption when the oxygen partial pressure is more than 15.96kpa (120 mmHg) (see blood gas acid-base analysis and relevant blood gas books at home and abroad).
5. Quantifying blood and qi samples: the quantification of the blood-gas sample refers to the quantification of the anticoagulant and the quantification of the blood collection. The amount of anticoagulant and the blood sampling amount of the syringe are completely dependent on the experience of operators, the biochemical result of blood gas can be influenced when the anticoagulant is too much, and the blood coagulation phenomenon can be generated when the anticoagulant is too little.
6. Difficulty in hemostasis: the injector adopts a thick needle, so the injector has large damage to arterial blood vessels, long hemostasis time (10-15 minutes) and easy generation of thrombus.
Therefore, in the medical care field, the blood gas sampler (blood gas needle) is generally used for collecting blood gas samples, so that the problems of automatic blood collection and blood collection quantity (partial quantification) quantification can be solved, namely the problem of anticoagulant quantification is solved, and the collection of arterial blood is simple and convenient.
The existing products, such as a micro blood gas collector manufactured by roche diagnostics ltd, germany, are tools which are commonly used for collecting blood gas samples in the field of medical care in China. Can realize quantitative micro blood sampling.
However, the existing products still have some places which are not convenient enough and do not meet the requirements of hospital sense in the using process:
1. the micro blood gas hemostix is a medical consumable material which is very commonly used clinically, and when medical staff collects micro arterial blood for a patient, the blood gas is analyzed after the collection is finished. Before trace blood gas hemostix is connected with blood gas analysis appearance, at first take off the sealing plug on syringe needle (5) and hemostix casing (2), then correspond blood gas analysis appearance probe butt joint with taper joint (7) of trace blood gas hemostix and carry out blood gas analysis, its process is more time-consuming, and humanized not strong, can have blood leakage and cross contamination's risk moreover, for example: when the trace amount blood gas hemostix gathered arterial blood and need utilized the blood gas analysis appearance, need take off the sealing plug on casing (2), make arterial blood and atmosphere be in the on-state, because of blood contacts with the atmosphere for a long time, oxygen and carbon dioxide concentration that can lead to in the blood change, influence the accuracy that detects data to and medical personnel's operation is improper or the intraductal arterial blood of maloperation collection will spill over, then can lead to unable detection. Therefore, if the action of the sealing plug on the shell (2) is reduced or removed in the blood gas analysis process after the medical staff collects the arterial blood for the patient, the workload of the medical staff can be reduced, the detection time is shortened, and meanwhile, the phenomena that the concentration of oxygen and carbon dioxide in the blood is changed to influence the accuracy of detection data and the arterial blood in a micro blood sampling tube overflows due to improper misoperation and operation because the blood is contacted with the atmosphere for a long time after the sealing plug is removed can be effectively avoided. Therefore, the method has important clinical significance and social value for preventing medical accidents.
2. Patent CN201820618562.6 a trace amount of blood gas hemostix with a check valve, which is a traditional trace amount of blood gas hemostix, wherein the check valve is added and used in cooperation with the traditional trace amount of blood gas hemostix, during the blood gas analysis process, when the blood gas analyzer absorbs the blood in the trace amount of blood gas hemostix, the check valve opens the opening channel of the check valve due to the suction effect, so that the blood channel is communicated with the atmosphere, and the blood gas analyzer can directly and easily extract the blood in the trace amount of blood gas hemostix for detection; however, during blood collection, the glass capillary tube generates positive pressure along with the entering of blood, the one-way valve is closed, and finally, sufficient blood volume cannot be collected, so that the glass capillary tube cannot be applied to practical use and has no clinical significance.
