Embodiment 1

[0017] like figure 1 As shown, the blood synchronous separation test device of the present invention uses a cylindrical housing 1 as the main body of the device, and its front and rear ends are sealed by the front sealing plug 2 and the rear sealing plug 3; one end of the separation sensing film 4 passes through the front sealing plug 2 into the housing, and the other end is outside the housing; the reference electrode 5 and the counter electrode 6 go deep into the housing from the housing wall and are placed on both sides of the separation sensing membrane 4; the blood feeding tube 7 is connected to the rear sealing plug 3 And connected to the housing; the serum discharge pipe 8 is wrapped around the outer end of the separation sensing membrane 4; the inner cavity of the outer end of the separation sensing membrane 4 by the working wire 9 goes deep into the other end.

[0018] The separation sensing membrane is fixed in the middle of the front sealing plug and does not touch ...

Embodiment 2

[0029] Refer to attached figure 1 , the preferred dimensions of the blood synchronous separation test device of the present invention are described in detail.

[0030] The airtight cylindrical housing 1 has a bottom diameter of 1.2 cm and a height of 7 cm.

[0031] The diameters of the front end sealing plug 2 and the rear end sealing plug 3 match the housing diameter, and the height is 1 cm.

[0032] The separation sensing membrane 4 is a hollow tube structure with an outer diameter of 1.2mm, an inner diameter of 0.9mm, a tube length of 7cm, a pore diameter of 20nm, and a height of 1.5cm protruding from the sealing plug 2 at the front end.

[0033] The reference electrode 5 and the counter electrode 6 are L-shaped metal wires with a total length of 5 cm, a horizontal end of 1 cm, and a vertical section 0.4 cm away from the shell wall.

[0034] The length of the blood feed pipe 7, the serum discharge pipe 8 and the working wire 9 can be adjusted according to actual needs.

Abstract

The invention relates to a blood synchronously separating and detecting device which is composed of: an airtight column shell body (1), a front end sealing plug (2), a rear end sealing plug (3), a separation sensing membrane (4), a reference electrode (5), a counter electrode (6), a blood inlet pipe (7), a serum outlet pipe (8) and a work wire (9). The front end sealing plug (2) and the rear end sealing plug (3) seal the front and the rear ends of the shell body (1). The separation sensing membrane (4) enters the shell body through the front end sealing plug (2). The reference electrode (5) and the counter electrode (6) deeply enter the shell body through the wall of the airtight column shell body and are arranged separately at the two sides of the separation sensing membrane (4). The blood inlet pipe (7) is connected to the rear end sealing plug (3) and is communicated with the shell body. The serum outlet pipe (8) tightly coats the separation sensing membrane (4). The work wire (9) deeply enters from an inner chamber in an outer end of the separation sensing membrane (4) to the other end. The device has simple structure, has both separation and sensing functions, can quickly complete blood test operation in situ, and greatly improves diagnosis efficiency in a hospital.

Description

technical field [0001] The invention relates to a device for synchronous separation and testing of blood. The prepared device can be used in the rapid extraction of serum in medical diagnosis and the detection of the concentration of important components such as blood sugar, blood lactic acid, blood glutamic acid, transaminase and protein in blood. Background technique [0002] The diagnosis of most diseases in modern hospitals relies on blood test technology, through the specific chemical reaction of the target components in the blood, the content of the components is calibrated to determine the cause of the disease. Because the blood is easy to coagulate and solidify, and the large-sized blood cells will increase the viscosity of the blood, which will have a certain impact on the analysis results. Therefore, most of the blood biochemical indicators are based on serum tests. Usually, serum extraction in hospitals mainly relies on centrifugation: a coagulant is added to fre...
