Embodiment 1

[0024] figure 1 The formula is a self-filling arterial blood collection device, which includes a blood collection tube 2 and a silicone plug 3 arranged at the end of the blood collection tube 2, and the silicone plug 3 is provided with a vent 4 communicating with the blood collection tube 2. The air-permeable hole 4 is provided with a gas-permeable and liquid-tight sealing film 5. This structure is the basic structure of a self-filling arterial blood sampling device. When blood is collected, the blood sample is injected into the blood collection tube 2 under the action of the pressure of the arterial blood vessel. Since the tail end of the blood collection tube 2 is provided with a vent 4, it can ensure that the blood sample is injected into the blood collection tube 2 The venting of the blood sample can be smoothly injected. At the same time, the air-permeable and liquid-impermeable sealing film 5 is arranged in the vent 4 to ensure that the blood sample will not overflow from ...

Abstract

The invention discloses a mixing device for a blood collector. The mixing device for the blood collector is used for mixing blood samples and anticoagulants and comprises a columnar mixing body with two ends open, a blood taking needle connection seat is arranged at one open end of the columnar mixing body while a blood taking tube connection seat is arranged at the other open end of the columnar mixing body, heparin anticoagulant pieces are arranged on the inner wall of the columnar mixing body, and a metal mixing ball is arranged in the columnar mixing body. The invention further discloses a self-filling arterial blood collector with the mixing device for the blood collector. The mixing device for the blood collector and the self-filling arterial blood collector have the advantages that anticoagulation effects in arterial blood collection and accuracy of blood gas analysis results can be improved, and blood samples can be taken out conveniently owing to automatic air feeding and discharging functions.

Description

Technical field [0001] The invention belongs to the field of medical equipment, and specifically relates to a blood sampling device mixing device for mixing blood samples and anticoagulants. The invention also relates to a self-filling arterial blood sampling device. Background technique [0002] Clinically, it is often necessary to collect blood from the radial artery, forearm artery, femoral artery and other parts of the patient for blood gas analysis. At present, the arterial blood collection devices used clinically are mostly piston injection type, such as CN200920030045, CN201020554216, etc. Such blood collection devices need to be operated by both hands, and the blood collection dose is difficult to accurately control, and it is impossible to achieve micro blood collection. In addition, because the anticoagulant of the plunger injection blood collection device is usually directly applied to the inner wall, the dosage and concentration of the anticoagulant are difficult to a...
