Abstract

The invention provides an extracting device for urine specimens. The extracting device comprises a support assembly and a vacuum test tube. The support assembly comprises a body and a drainage pipeline. The body is provided with a drainage cavity. The drainage pipeline is arranged on the body and connected with the interior and the exterior of the drainage cavity. The two ends of the drainage pipeline are opened to ensure that liquid can pass. An edge part is formed at the top of the drainage pipeline. The head of the vacuum test tube is provided with a soft plug, and negative pressure vacuum is formed in the vacuum test tube. The vacuum test tube is buckled into the drainage cavity of the body downwards in an inverted mode. The vacuum test tube is pressed down to ensure that the edge part at the top of the drainage pipeline punctures the soft plug on a test tube opening to extend into the test tube. The extracting device is simple in structure, easy to operate, capable of extracting liquid quantitatively, safe and sanitary.

Description

A kind of extraction element of urine specimen

Technical field:

The present invention relates to medical science sample processing apparatus, the concrete extraction element with a kind of urine specimen is relevant.

Background technology:

In biomedical detection, during such as the detection of urine, it is necessary to urine specimen is loaded test tube, then test tube is put into and urinalysis instrument carries out Aulomatizeted Detect. The method that urine specimen loads test tube at present, adopts the mode toppled over. It is embodied as follows: first left and taken urine in cup by patient, then pours into manual for the urine in cup in test tube. Advantage of this is that with low cost, not enough place is, urine from big container pour test tube into time inconvenient operation, urine is easily trickled down outside test tube, trickles down at environment, is trickled down at operator's equivalent risk on hand, and then pollute the hands of test tube, contaminated environment, the operator that make dirty, there is also the phenomenons such as sampling amount is lack of standardization simultaneously.

Summary of the invention:

For the defect existed in prior art, the present invention provides the extraction element of a kind of urine specimen, and simple in construction is easy to operate, can quantify to extract urine, safety and sanitation.

For achieving the above object, technical solution of the present invention is:

A kind of extraction element of urine specimen, including: carriage assembly and vacuum test tube; Carriage assembly includes: body and drainage pipe, body has drainage lumens, drainage pipe is arranged on body and connects drainage lumens inside and out, drainage pipe both ends open ensures that liquid passes through, and sharp-pointed portion is formed on drainage pipe top, vacuum test tube head is with cork and is internally formed negative-pressure vacuum, and the downward back-off of vacuum test tube enters in the drainage lumens of body, and the sharp-pointed portion at lower pressure vacuum test tube guarantee drainage pipe top punctures the cork of test tube mouth and extend in test tube.

Further, described carriage assembly also includes a top guard protection vacuum test tube.

Further, described top guard includes a pole and is fixed on body upper part, and a rotating top plate is rotatable is hinged on pole top, steps down with vacuum test tube top and be easy to vacuum test tube of taking when rotating top plate rotates.

Further, described body is divided into upper and lower two chambers, respectively upper chamber and lower chambers by demarcation strip, and drainage pipe is fixed on demarcation strip and connects upper chamber and lower chambers.

Further, described body is a chamber, is described drainage lumens, and drainage pipe is fixed on drainage lumens base plate bottom and stretches out the inside and out connecting drainage lumens outside drainage lumens.

Adopt technique scheme; present configuration is simple; easy and simple to handle; during use; being outwarded winding by the rotating top plate of top guard and expose vacuum test tube, with hands downwardly against vacuum test tube, the cork of vacuum test tube supplements the sharp end of drainage tube and thrusts; under the effect of negative pressure, liquid can enter vacuum test tube by drainage needle.

Detailed description of the invention:

Below in conjunction with drawings and Examples, the present invention/invention is further illustrated.

It is the embodiment of the present invention one as Figure 1-4, the extraction element of a kind of urine specimen, including: carriage assembly 1 and vacuum test tube 2; Carriage assembly 1 includes: body 11 and drainage pipe 12, and body 11 is divided into upper and lower two chambers by demarcation strip 112, respectively upper chamber 113 and lower chambers 114, and drainage pipe 12 is fixed on demarcation strip 112 and connects upper chamber 113 and lower chambers 114; Drainage pipe 12 is arranged on body 11 and connects drainage lumens 111 inside and out; drainage pipe 12 both ends open ensures that liquid passes through; and sharp-pointed portion 121 is formed on drainage pipe 12 top; vacuum test tube 2 head with cork 21 and is internally formed negative-pressure vacuum; the downward back-off of vacuum test tube 2 enters in the upper chamber 113 of body 11; lower pressure vacuum test tube 2 ensures that the sharp-pointed portion 121 at drainage pipe 12 top punctures the cork 21 of test tube mouth and extend in test tube, and described carriage assembly 1 also includes a top guard 3 and protects vacuum test tube 2. In the particular embodiment, described top guard 3 includes a pole 31 and is fixed on body 11 top, and a rotating top plate 32 is rotatable is hinged on pole 31 top.

If Fig. 5 is embodiments of the invention two, described body 11 is a chamber, is described drainage lumens 111, and drainage pipe 12 is fixed on drainage lumens 111 base plate 115 bottom and stretches out the outer inside and out connecting drainage lumens 111 of drainage lumens 111.

Carriage assembly of the present invention includes body, drainage pipe and top guard, and the top of drainage pipe is tip-like, it is possible to thrust vacuum test tube; Top guard can rotate, and can take out vacuum test tube after turning on from body; The bottom cavity of body can protect drainage pipe, vacuum test tube head to be rubber stopper, it is possible to penetrating with needle point, the inside is negative-pressure vacuum, is used for sucking liquid.

During use, protecting device to expose vacuum test tube screw off top, with hands downwardly against vacuum test tube, the stopper of vacuum test tube thrusts the drainage needle at drainage pipe top, and under the effect of negative pressure, liquid can enter vacuum test tube by drainage needle. Present configuration is simple, easy to operate, can dose, safety and sanitation. It is not only used in the extraction of urine, it is also possible in extraction and the transfer of other liquid sample.
