Embodiment 1

[0039] Embodiment 1: Piston type isolation cavity

[0040] In this embodiment, the structure of the piston-type isolation cavity that can be connected with the blood collection needle is as follows:

[0041] The blood collection aid includes a tube body 1, a first interface 2, and a second interface 3; the tube body 1 is sequentially provided with an isolation cavity 4, a first pipeline 5, a second pipeline 6 and a pushable piston 7;

[0042] see figure 1 , 2 , the first pipeline 5 communicates with the first interface 2 and the isolation cavity 4 respectively; the first interface 2 can be connected with the blood collection needle, so that the collected front blood is placed in the isolation cavity;

[0043] see image 3 , 4 After the piston 7 can be pushed to move to the end of the isolation chamber 4, the second pipe 6 communicates with the first interface 2 and the second interface 3 respectively, so that the collected blood flows into the container that can be connect...

Embodiment 2

[0055] Embodiment 2: U-shaped tubular isolation cavity

[0056] In this embodiment, the structure of the U-shaped tubular isolation cavity that can be connected with the blood collection needle is as follows:

[0057] The blood collection aid includes a tube body 1, a first interface 2, and a second interface 3; the tube body 1 is provided with an isolation cavity 4; the tube body 1 is a U-shaped tube body, and one end of the tube body 1 is respectively provided with a first interface 2 and a second interface Two interface 3, the other end is closed.

[0058] The inside of the blood collection aid is sterile.

[0059] Preferably, the capacity of the isolation cavity is 0.01-10 mL.

[0060] Preferably, the isolation cavity is in a negative pressure state.

[0061] See the specific structure Figure 5 .

[0062] The method of use is as follows:

[0063] 1. Disinfect the patient's skin. The skin disinfection method has been recommended in the CLSI document and the blood cul...

Abstract

The invention relates to the technical field of blood culture, in particular to a blood sampling assistor, a blood sampling device and a method for reducing blood culture pollution rate. The blood sampling assistor comprises a tube body 1, a first interface 2 and a second interface 3, wherein the tube body 1 is provided with an isolation cavity 4. The blood sampling assistor and the blood samplingdevice can realize isolation of front-section blood of venous blood sampling, so that trace skin colonization bacteria are isolated in the cavity, and the blood culture pollution rate can be reduced.

Description

technical field [0001] The invention relates to the technical field of blood culture, in particular to a blood collection aid, a blood collection device and a method for reducing the contamination rate of blood culture. Background technique [0002] In hospital clinical and medical research trials, automated blood culture is a microbiological examination method used to test the presence or absence of bacteria in blood samples. It is very important to have bacterial growth to confirm the diagnosis, so blood culture is one of the most important and common bacterial testing items. At present, the instruments and matching blood culture bottles used clinically for blood culture mainly rely on imports, such as the Bactct 9000 series of the American BD company and the French Mérieux Bact / Alert3D, which usually use the silicone rubber on the bottom of the coating and the culture bottle Sensor, based on bottom sensor fluorescence or color sensing method to observe CO produced during...
