TECHNICAL FIELD

[0001] The utility model relates to handle test tube technical field, concretely relates to a double -ear formula specimen pretreatment test tube. BACKGROUND

[0002] In the patent application number as 202211302048.9 proposed a kind of based on specific structure test tube's leucorrhea specimen pretreatment device, it discloses including: test tube, test tube includes: test tube cover, test tube body and cotton swab, test tube cover is connected at the top of test tube body, cotton swab is through test tube cover and is inserted into test tube body, test tube cover is provided with cotton swab stirring mouth and gun head sampling mouth, cotton swab stirring mouth is provided with guide inner edge between gun head sampling mouth, the end of cotton swab stirring mouth away from gun head sampling mouth is provided with limit edge, test tube body is provided with cotton swab mixing cavity, sample liquid straight-through cavity and sample liquid sampling cavity, cotton swab mixing cavity, sample liquid straight-through cavity and sample liquid sampling cavity are interconnected.The test tube of the application separates the mixing position and sampling position of sample liquid, so that mixing process and sampling process do not interfere with each other;

[0003] But there are certain problems in actual use, because the top height of cotton swab stirring mouth and the top height of gun head sampling mouth are designed to be the same or similar, which increases the misjudgment risk when operating to some extent. Especially in fast or nervous experimental environment, the operator is easy to insert the cotton swab into the gun head sampling mouth due to visual confusion or careless operation, at this time, the sample gun cannot sample through the gun head sampling mouth, resulting in sample processing failure.

[0004] Therefore, a double-ear specimen pretreatment test tube is needed to overcome the occurrence of the above problems. UTILITY MODEL CONTENT

[0005] In order to solve the above problems, the utility model embodiment provides a double-ear specimen pretreatment test tube, which realizes the purpose of solving the problems in the background art.

[0006] In order to realize the above-mentioned purpose, the utility model embodiment specifically adopts the following technical scheme: a double-ear specimen pretreatment test tube, comprising a test tube main body, the test tube main body includes a sample tube and a treatment tube fixedly connected and communicated on one side of the sample tube, the top of the sample tube is protruded from the top of the treatment tube, and the sample tube is inclinedly arranged on one side of the treatment tube.

[0007] As a further improvement of the above technical scheme:

[0008] The horizontal height of the bottom of the sample tube is higher than that of the bottom of the treatment tube, and the bottom of the sample tube is communicated with the treatment tube.

[0009] The sample tube and the treatment tube are both inverted conical.

[0010] The annular scale line is arranged on the test tube body.

[0011] The limiting ring is arranged on the test tube body.

[0012] The grabbing ring is arranged on the top of the test tube body.

[0013] The beneficial effects of the embodiment of the utility model are as follows:

[0014] The horizontal height of the top of the sample tube is higher than the horizontal height of the top of the processing tube, that is, the top of the sample tube is higher than the top of the processing tube, so that the sample tube and the processing tube are distinguished, thereby preventing the case that the insertion position of the cotton swab is wrong; meanwhile, the sample tube is arranged obliquely, and the processing tube is arranged vertically, thereby further facilitating the distinction between the sample tube and the processing tube.

[0020] The preferred embodiments of the utility model are described below with reference to the drawings. Those skilled in the art should understand that these embodiments are only used for explaining the technical principles of the utility model, and are not intended to limit the protection scope of the utility model.

[0021] Referring to Figs. 1 to 3 , the utility model embodiment discloses a double-ear type specimen pre-treatment test tube, including test tube body 1, test tube body 1 includes sample tube 11 and fixedly connected and communicated processing tube 12 on one side of sample tube 11, the top of sample tube 11 is arranged to protrude from the top of processing tube 12, and sample tube 11 is arranged obliquely on one side of processing tube 12.

[0022] During the sample pretreatment, the sampled cotton swab is inserted into the sample tube 11, then the sample gun injects the diluent into the sample tube 11, and then the diluent is extracted from the bottom of the treatment tube 12 for a certain number of times. The diluent is continuously extracted and injected by the sample gun, the liquid level of the diluent in the test tube body 1 is quickly changed, the sample on the cotton swab is eluted by the continuous rising and falling of the liquid level, so that the sample is separated from the cotton swab and dissolved in the diluent, thereby completing the sample pretreatment.

[0023] The horizontal height of the top of the sample tube 11 is higher than the horizontal height of the top of the treatment tube 12, that is, the top of the sample tube 11 is higher than the top of the treatment tube 12, so as to distinguish the sample tube 11 from the treatment tube 12, thereby preventing the error of the insertion position of the cotton swab. At the same time, the sample tube 11 is inclined, and the treatment tube 12 is vertical, thereby further distinguishing the sample tube 11 from the treatment tube 12.

[0024] As a further description of the present application:

[0025] The horizontal height of the bottom of the sample tube 11 is higher than the horizontal height of the bottom of the treatment tube 12, and the bottom of the sample tube 11 is communicated with the treatment tube 12.

[0026] Since the horizontal height of the bottom of the treatment tube 12 is lower than the horizontal height of the bottom of the sample tube 11, and the bottom of the sample tube 11 is communicated with the treatment tube 12, when the diluent is injected into the sample tube 11, the diluent will flow from the sample tube 11 into the treatment tube 12, that is, the cotton swab can be washed by the flowing diluent, so as to elute the sample into the diluent.

[0027] As a further description of the present application:

[0028] The sample tube 11 and the treatment tube 12 are both inverted conical, so that the diameters of the bottoms of the sample tube 11 and the treatment tube 12 are small, that is, after the diluent is added, the liquid level of the diluent is high, and the head of the cotton swab can be completely soaked in the diluent.

[0029] As a further description of the present application:

[0030] The annular scale line 2 is arranged on the test tube body 1, so as to display the added amount of the diluent.

[0031] As a further description of the present application:

[0032] The limiting ring 3 is arranged on the test tube body 1. During the treatment, the test tube body 1 is placed on the sample rack, and the limiting ring 3 is used to clamp the test tube body 1 into the sample rack, so as to prevent the test tube body 1 from being lifted during the extraction and injection of the diluent by the sample gun.

[0033] As a further description of the present application:

[0034] The top of the test tube body 1 is provided with a gripping ring 4, which makes it easy for the user to grip the test tube body 1. At the same time, the gripping ring 4 and the limiting ring 3 can increase the thickness of this part of the test tube body 1, thereby improving the strength of the test tube body 1.
