Description
Technical Field
The utility model relates to a urine collection system especially discloses a middle section urine sample collection device who stays catheter.
Background
The midstream urine collection device that present clinical adoption was aimed at not keeping somewhere the patient of ureter more. And the number of devices for taking mid-stream urine is less for patients who keep catheters. Only two are commonly used clinically: one is to use a 20ml syringe to puncture the end of the catheter, and inject the specimen into the specimen box after the specimen is extracted. And the other way is to disconnect the connection part of the tail end of the catheter and the urine collection bag and then to reserve a urine sample. The disadvantages of these two approaches are: 1. the operation is complex, the steps are more, the exposure time of the urine specimen in the air is long, and the culture result is easy to be inaccurate; 2. the collection amount of the sample cannot be controlled, so that the collection fails; 3. repeated operation increases the workload of medical personnel and wastes resources.
Disclosure of Invention
An object of the utility model is to overcome the defect that exists among the prior art, provide an easy operation, gather the success rate height, prevent that the sample from by other pollutant such as air pollution keep somewhere middle section urine sample collection device of catheter.
The utility model discloses a realize like this: a middle section urine sample collecting device of an indwelling catheter comprises an extrusion kettle, a flow guide pipe, a needle head and a urine collecting cup, wherein the flow guide pipe comprises a transverse guide pipe and a vertical guide pipe, the vertical guide pipe is vertically connected to the middle part of the transverse guide pipe, one end of the transverse guide pipe is connected with the extrusion kettle, a first one-way valve is arranged between the extrusion kettle and the transverse guide pipe, and the other end of the transverse guide pipe is connected with the needle head through a connecting joint; the urine collecting cup is characterized in that a cup cover is arranged at the top of the urine collecting cup, a threaded connector is arranged on the cup cover, the lower end of the vertical guide pipe is connected with the urine collecting cup through the threaded connector, and a switch control valve is arranged on the vertical guide pipe.
And a second one-way valve is arranged at the lower end of the threaded connector.
The urine collecting cup is a negative pressure urine collecting cup.
The urine collecting cup is provided with scales.
The urine collecting cup is characterized in that a groove is formed in the cup cover of the urine collecting cup, a sealing cover matched with the threaded connector is embedded in the groove, the sealing cover is connected with the groove in a pluggable mode, and a handle is arranged at one end of the top of the sealing cover.
The pluggable connection is as follows: the side wall of the sealing cover is provided with an elastic raised line, and the inner wall of the groove is provided with an annular groove clamped with the elastic raised line.
The outside cover of syringe needle is equipped with the needle cap.
The utility model has the advantages that: through extrusion kettle, honeycomb duct and syringe needle utilize the negative pressure to collect the urine sample, easy operation, and the success rate is high. Prevent the urine specimen from being polluted by air and the like. The negative pressure of the extrusion kettle is in direct proportion to the volume of the urine collecting cup, so that the amount of the samples can be well controlled, and the culture result is prevented from being influenced by too many and too few samples. Through first check valve, second check valve, can effectively prevent urine adverse current, reduce the risk of patient's infection. The utility model discloses simple structure, part are few, and waste classification is simple, has reduced clinical medical personnel occupation exposure. The urine collecting cup is provided with scales, so that the accuracy of the sample measurement is ensured.
