Description

Urine culture specimen collector

Technical Field

The utility model relates to a sample collection technical field is cultivateed to urine, especially relates to a sample collector is cultivateed to urine.

Background

Urine culture refers to an artificial culture method in which a urine specimen is collected, inoculated onto a culture medium, cultured for a certain period of time at a certain temperature, humidity, gas environment, etc., to grow bacteria, and identified, thereby determining pathogenic bacteria.

The urine culture specimen is generally collected in a specimen tube shown in fig. 4, the specimen tube includes a specimen tube body and a specimen tube cover, and the specimen tube cover is connected with the specimen tube body by screw threads. The sample tube is thin and small in volume, so that urine cannot be directly urinated into the sample tube, otherwise, the urine cannot be spilled freely. Although a container such as a urine cup can be used for receiving urine and then the urine is poured into the sample tube, the urine pollution is easily caused in the process.

To collect urine culture samples just for the first time, some patents disclose urine culture sample collectors.

ZL201720638113.3 discloses a urine culture collector for male infants, which comprises a urine receiving cylinder body, a first catheter, a second catheter, a urine culture pipe, a urine storage device and a three-way pipe, wherein the urine receiving cylinder body is used for being fixed at the vulva of a patient to collect urine, the urine receiving cylinder body, the first catheter and the second catheter are in sealing connection through the three-way pipe, the three-way pipe comprises a switch, the switch is used for switching the flow direction of the urine to the first catheter or the second catheter, the first catheter is in sealing connection with the urine storage device, the urine storage device is used for collecting waste urine, the second catheter is in sealing connection with the urine culture pipe, and the urine culture pipe is used for collecting middle-section urine.

This sample collector is cultivateed to urine switches the urine flow direction through operating the three-way valve, and control urine flows in and stores up urine ware or sample pipe to gather the middle section urine. The culture specimen collector also has its drawbacks. One, because the sample pipe volume is little, the sample pipe is just filled soon to the urine to can persist in the pipeline of connecting the sample pipe, the back is pulled down to the sample pipe, persists the urine outflow in the pipeline, causes the pollution easily. Secondly, a three-way valve is adopted to control the urine trend, the three-way valve main body needs to be held by one hand, and the valve knob needs to be operated by the other hand; therefore, the urine receiving barrel body cannot be held by hands when both hands are occupied, and therefore, the collection of urine samples is difficult to finish by a single person; and the operation speed is slow, and the opportunity for collecting the midstream urine is easy to miss.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1 and 2, the urine culture sample collector comprises a urine receiving funnel 1, a main catheter 2, a connector 3, a sample tube 81 and a lateral catheter 4, wherein the urine receiving funnel 1 is connected with the upper end of the main catheter 2, the connector 3 is connected with the lower end of the main catheter 2, the connector 3 is provided with a bypass hole 31, the sample tube 81 is in threaded connection with the connector 3, the upper end of the sample tube 81 corresponds to the bypass hole 31, and the lateral catheter 4 is connected with the connector 3 and is communicated with the bypass hole 31.

When the urine culture specimen is collected, a urine culture specimen collector is taken. The sample tube 81 of the urine culture sample collecting device is obtained by removing the sample tube cover 82 of the conventional sample tube 8 shown in fig. 4. The urethral orifice of the patient is disinfected, and then the urine receiving funnel 1 is directed to the urethral orifice. Urine excreted by the patient enters the specimen tube body 81 along the urethral catheter main tube 2 for collection. After the sample tube 81 is filled with the urine, since the connection head 3 has the bypass hole 31, the upper end of the sample tube 81 corresponds to the position of the bypass hole 31, and the urine of the sample tube 81 directly flows out from the bypass hole 31 and the urine guiding side tube 4 after overflowing. After the collection of urine sample is accomplished, no urine is remained in the pipeline, directly pull down the sample body 81, with sample tube lid 82 cover on sample body 81 can, can avoid remaining urine in the urine cultivation sample collector to flow out and cause the pollution.

The upper end of the specimen tube body 81 corresponds to the position of the bypass hole 31, and it is particularly preferable that the upper end of the specimen tube body 81 is located between the center of the bypass hole 31 and the lower edge of the bypass hole 31. So that the urine in the sample tube 81 can directly flow out from the bypass hole 31 and the catheter 4 after overflowing.

The urine flowing out of the urethral catheterization side tube 4 can be directly discharged, and can also be collected by a urine bag. In order to be able to collect the urine flowing out of the catheter 4 with a urine bag, the urine culture specimen collector comprises a urine bag connector 5, and the urine bag connector 5 is connected with the catheter 4.

The urine culture sample generally requires midstream urine, and for a patient with urine suffocating convenience, a part of urine can be firstly output by the urine, and then the midstream urine is collected by using the urine culture sample collector. For people with difficulty in holding urine, such as infants, this is difficult to achieve. Therefore, the utility model discloses an it cultivates sample collector to prefer urine includes catheterization branch pipe 6, and catheterization branch pipe 6 is connected with catheterization person in charge 2 and catheterization side pipe 4.

Thus, the main catheter 2 under the catheter branch tube 6 can be pinched closed, and the urine excreted by the patient enters the side catheter tube 4 from the catheter branch tube 6 and flows out. Then, if the hand is released, the midstream urine flows into the specimen tube 81. The operation can be carried out by one hand, and the operation is convenient; and the operation is quick, and the time for collecting the midstream urine can be avoided from being missed.

For further facilitation, the main catheter tube 2 below the catheter branch tube 6 is closed. Preferably, the urine culture specimen collector includes a pincher 7, and the pincher 7 is provided on the main catheter 2 below the catheter branch 6 and near the catheter branch 6. The clamp 7 is thus operable to clamp the catheter main tube 2.

The clipping device 7 should be easy to operate with one hand, for which reason it is preferred that the clipping device 7 comprises a connecting sleeve 71 and two elastic strips 72, the connecting sleeve 71 being fitted over the catheter main tube 2, the two elastic strips 72 being located on either side of the catheter main tube 2 and being connected to the connecting sleeve 71. The two elastic pieces 72 are pinched, and the main catheter 2 can be clamped and closed by the inward swing of the elastic pieces 72. After the hand is released, the elastic sheet 72 rebounds to the catheter main tube 2 to open.

In order to adapt to different physiological structures of men and women, the urine receiving funnel 1 is preferably in threaded connection with the main catheter 2, the urine receiving funnel 1 is one of the male urine receiving funnel 11 and the female urine receiving funnel 12, the mouth of the male urine receiving funnel 11 is circular, and the mouth of the female urine receiving funnel 12 is elliptical. The form of the urine receiving funnel 1 can thus be selected according to the sex of the patient.
