2. Description of the Related Art Conventionally, blood collection using a reduced-pressure blood collection tube is performed by piercing a vein with a blood collection needle using a device as disclosed in Japanese Utility Model Publication No. 50-35584 and suctioning by negative pressure of the reduced-pressure blood collection tube. It is being appreciated.

However, when the venous pressure is low as in the case of old people or children and the blood volume of the patient is small, the blood vessel wall of the vein is sucked by the negative pressure of the blood collecting needle due to the negative pressure during the blood collection. , Sometimes the hole of the blood collection needle was blocked and it was not possible to collect blood. Also, for the same reason, the blood vessel wall of the vein may be damaged, causing internal bleeding.

Embodiments of the present invention will be described below. FIG. 1 is a configuration diagram showing an example of a medical device for blood collection of the present invention. In FIG. 1, a holder 7 into which a reduced pressure blood collection tube 9 made of a tube tightly fitted with a rubber stopper 8 can be slidably fitted, and a catheter 3 made of a soft tube having a blood collection needle 1 are attached to one end of the holder 7. Needle base 4 and needle base 4
A communication needle 5 which is provided on the holder and is capable of communicating the reduced pressure blood collection tube 9 and the catheter 3 after the reduced pressure blood collection tube 9 is attached to the holder 7.
And a sealing rubber tube 6 fitted to the communication needle 5, which is a medical instrument for blood collection in which a roller clamp 2 is provided as a pressure loss adjusting mechanism in the blood flow path of the catheter.

【0007】本発明の操作は次の手順とする。 (1)連通針5をホルダー7にセットする。 (2)クランプ2を全閉にする。 (3)採血針1で血管に穿刺する。 (4)減圧採血管9をホルダー7に嵌合させる。 (5)クランプ2を徐々に開放し、採血を行う。The operation of the present invention is as follows. (1) Set the communication needle 5 in the holder 7. (2) Fully close the clamp 2. (3) Puncture the blood vessel with the blood collection needle 1. (4) The reduced pressure blood collection tube 9 is fitted into the holder 7. (5) Gradually open the clamp 2 and collect blood.

EFFECTS OF THE INVENTION Since the present invention is constructed as described above, it is possible to perform safe and reliable blood collection for a person having a low venous pressure such as an elderly person or a child and a patient having a small blood flow rate.
Since the negative pressure is not applied to the blade when the blood collection needle is connected to the blood collection needle, the blood vessel wall is not sucked to the blade. Since the blood collection volume can be adjusted, the blood vessel wall is not sucked to the blade edge during blood collection.
