Self-enclosed peripheral blood collection pipe

Abstract

The invention discloses a self-enclosed peripheral blood collection pipe which comprises a collection pipe and a gathering pipe, wherein the collection pipe is made of polypropylene, and the inner wall of the collection pipe is siliconized; a pipe cap sleeved with a pipe mouth at the top of the gathering pipe is arranged, the pipe cap is made of elastic materials and composed of a cap cover and a cap body; the cap body is a cylindrical component with an H-shaped axial cross section, and the cap cover is a valgus flange edge connected to the top of the cap body; the outer wall of the lower end of the cap body is provided with 3-5 raised arc rings so as to form an elastic tension structure; and the lower-middle part of the inner wall of the cap body is connected with a sealing cover, and the sealing cover is a thin-wall component with a V-shaped axial cross section and provided with 3-6 straight slits passing through the center of the sealing cover so as to form a self-enclosed structure. The self-enclosed peripheral blood collection pipe disclosed by the invention is simple in structure and easy to operate; the acquisition process is continuously performed in an enclosed mode; the acquisition time and collection time are short, and the acquisition and collection efficiencies are high; and the biochemical pollution caused by shifting in the acquisition process can be avoided.

Description

technical field [0001] The invention relates to a medical device, in particular to a collection device for collecting peripheral blood of a human body. Background technique [0002] Medical institutions often need to collect peripheral blood from the human body for testing. At present, it is basically used to collect the peripheral blood of the human body with a slender collection tube with a suction ball, and then extend the mouth of the collection tube into the collection tube to put the peripheral blood pressure into In the collection tube, the collection tube is placed in the laboratory for detection and chemical analysis. This method is simple and easy to operate, but there are some problems in this method: First, when collecting peripheral blood, it needs to be collected with the collection tube first, and then Pressed into the collection tube, the collection and collection process needs to be shifted to complete, and it is easy to cause biochemical pollution during th...

[0002] Medical institutions often need to collect peripheral blood from the human body for testing. At present, it is basically used to collect the peripheral blood of the human body with a slender collection tube with a suction ball, and then extend the mouth of the collection tube into the collection tube to put the peripheral blood pressure into In the collection tube, the collection tube is placed in the laboratory for detection and chemical analysis. This method is simple and easy to operate, but there are some problems in this method: First, when collecting peripheral blood, it needs to be collected with the collection tube first, and then Pressed into the collection tube, the collection and collection process needs to be shifted to complete, and it is easy to cause biochemical pollution during the moving process; second, sometimes it needs to collect multiple times to collect the specified volume of peripheral blood, and the collection and collection time is longer; The second is that at present, the domestic slender collection tube is generally made of glass. When using this collection tube to collect peripheral blood from children, if the child's hand moves agitatedly, the slender collection tube made of glass is more likely to cut the child's blood. hand
