Description

Be used for serum to detect quantity and get device

Technical Field

The utility model relates to a serum detection area, concretely relates to be used for serum to detect quantity and get device.

Background

The immunological examination is a kind of physiological function test that the organism recognizes self and non-self antigens, forms natural immune tolerance to autoantibodies and produces rejection to non-self antigens. Under normal conditions, the physiological function is beneficial to the organism and can generate the immune protection effects of resisting infection, resisting tumor and the like, maintaining the physiological balance of the organism and stabilizing the organism. Under certain conditions, when immune function is disturbed, harmful reactions and consequences can also occur to the body, such as induction of hypersensitivity, autoimmune diseases and tumors. The immunological detection of serum is the main immunological examination. The inspection contents are mainly as follows: immunoglobulin g (igg), immunoglobulin a (iga), immunoglobulin m (igm), immunoglobulin d (igd), immunoglobulin e (ige), cardiac troponin t (ctnt), myoglobin (Mb), Rheumatoid Factor (RF).

In the serum detection process, a dropper is generally used for extracting sample serum, and then the dropper has the defect that quantitative sampling cannot be carried out, so that a certain error exists in the detection result.

An object of the utility model is to overcome prior art's not enough, provide one kind and be used for serum to detect quantity and get device, through improving traditional glass burette, make it realize the ration sample.

The purpose of the utility model is realized through the following technical scheme:

the utility model provides a be used for serum to detect quantity and get device, the device includes straw body and nipple, the nipple is installed straw body top, the straw body comprises sharp mouth section and straight tube section, the mouth is drawn to sharp mouth section bottom offering, the built-in one section inner tube of straight tube section, the overflow mouth is seted up at the inner tube top, inner tube bottom opening with sharp mouth section switches on, and the outside is extended outward in inner tube bottom with straight tube section inner wall integrated into one piece forms sealedly, the inner tube outer wall with form the slowly-releasing appearance chamber between the inner wall of straight tube section.

This scheme is in order to realize the quantitative sample of serum, improve traditional burette, with one section inner tube of the intraductal increase of sharp mouth glass, make inner tube bottom and sharp mouth section switch on, the inner tube top sets up the overflow mouth, make inner tube and sharp mouth section form one section capacity fixed appearance chamber, when the sample, after inner tube and sharp mouth section wash full sample, unnecessary serum sample then enters into the slowly-releasing through the overflow mouth and holds the intracavity, the sample of slowly-releasing appearance intracavity can't the backward flow again during extrusion rubber nipple, thereby realize quantitative sample.

Furthermore, a liquid outlet flush with the bottom of the slow release cavity is formed in the side face of the bottom of the straight pipe section, the liquid outlet is sealed through a piston, and the liquid outlet and the piston are arranged to facilitate cleaning of the dropper so as to be convenient for disinfection and secondary use.

Furthermore, the bottom of the slow release cavity and the outer wall of the inner tube are designed to be chamfers, and the chamfers are designed to facilitate the discharge and cleaning of samples.

Furthermore, the overflow port is an upward convex sharp nozzle, the outer wall of the overflow port is designed into an inclined curved part, and the overflow port is designed into the convex sharp nozzle, so that the overflow of redundant liquid can be facilitated, and the backflow phenomenon is avoided.

Furthermore, the caliber size of the overflow port is larger than that of the suction port, and the design aims to ensure that the overflow speed is larger than the suction speed so as to ensure a good overflow effect.

Further, the slow release cavity is a cavity between the outer wall of the inner pipe and the interior of the straight pipe section, and the height of the slow release cavity is corresponding to the height from the bottom of the inner pipe to the overflow port;

the capacity of the slow release cavity meets the following requirements: the capacity of the slow release containing cavity, the capacity of the inner tube and the capacity of the sharp mouth section are more than or equal to the maximum suction quantity of the nipple.

The purpose of this design is to guarantee no matter how to squeeze the nipple, the overflow sample after absorbing the sample can not overflow the overflow mouth and cause the phenomenon that unnecessary sample flows back to the inner tube.

The utility model has the advantages that: compared with the traditional dropper, the novel dropper is provided with the inner tube communicated with the tip nozzle in the dropper, the overflow port is formed in the top of the inner tube, and the straight tube section side wall is sealed at the bottom of the inner tube, so that a slow release cavity is formed, a sample exceeding the tip nozzle section of the dropper and the inner tube enters the slow release cavity, and the purpose of quantitative sampling is achieved.

Detailed Description

The technical solution of the present invention is described in further detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the following description.

As shown in figure 1, the device for measuring and taking serum comprises a straw body 100 and a rubber nipple 200, wherein the straw body 100 is a sharp-mouth glass tube, the rubber nipple 200 is arranged at the top of the sharp-mouth glass tube, the sharp-mouth glass tube consists of a sharp-mouth section 101 and a straight tube section 102, and the bottom of the sharp-mouth section 101 is provided with a suction port 103.

As a further improvement of this embodiment, a section of inner tube 300 is disposed inside the straight tube section 102, an overflow port 301 is formed at the top of the inner tube 300, an opening at the bottom of the inner tube 300 is communicated with the tip section 101, the outer side of the bottom of the inner tube 300 extends outward to form a seal with the inner wall of the straight tube section 102 by integral molding, which is equivalent to that the bottom of the inner tube 300 separates the tip section 101 from the straight tube section 102, so that the inner tube 300 serves as a communication channel between the tip section 101 and the straight tube section 102, and liquid entering the straight tube section 102 from the tip section 101 must pass through the. A slow release cavity is formed between the outer wall of the inner tube 300 and the inner wall of the straight tube section 102, so that liquid passing through the inner tube 300 enters the slow release cavity and cannot flow back. The side surface of the bottom of the straight pipe section 102 is provided with a liquid outlet 104 which is flush with the bottom of the slow release cavity, and the liquid outlet 104 is sealed by a piston 400.

As a preferred embodiment, as shown in FIG. 2, the bottom of the slow release cavity and the outer wall of the inner tube 300 are designed to be a chamfer 302, the overflow port 301 is a tip protruding upwards, the outer wall of the overflow port 301 is designed to be an inclined curved part 303, and the caliber size of the overflow port 301 is larger than that of the suction port 103.

As a preferred embodiment, the slow release cavity is a cavity between the outer wall of the inner tube 300 and the inside of the straight tube section 102, and the height of the cavity is corresponding to the height from the bottom of the inner tube 300 to the overflow port 301; the capacity of the slow release cavity meets the following requirements: the capacity of the slow release cavity, the capacity of the inner tube 300 and the capacity of the sharp mouth section 101 are more than or equal to the maximum suction quantity of the nipple 200.
