Description

Technical Field

[0001] The invention belongs to the technical field of medical examination, and in particular relates to a urine collecting device for medical examination. Background Art

[0002] Urine testing is one of the three routine medical tests. Urine testing has important reference value for the early diagnosis of kidney lesions. In medicine, normal urine is divided into three sections, namely initial urine, mid-section urine and final urine. Because mid-section urine is a normal urine with the least pollution in the human body, most urine tests require mid-section urine. When the urine is retained for 24 hours, formaldehyde needs to be added to the urine for preservation. However, if the formaldehyde is not mixed in time after being added to the urine, it is easy to cause the formaldehyde to react with the urea in the urine to produce precipitates, which interferes with the inspection effect of the urine under a microscope. However, most existing urine collection devices are ordinary urine cups, which do not have the function of automatically collecting mid-section urine and automatically mixing formaldehyde after adding it to the urine. Summary of the invention

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a urine collection device for medical examination, which can automatically collect midstream urine and automatically mix urine with formaldehyde added.

The funnel 204 is arranged on the top of the annular plate 203. The inner diameter of the bottom of the funnel 204 is adapted to the outer diameter of the end face of the sampling tube 301.

[0026] When in use, the patient discharges urine into the funnel 204, and the urine flows along the funnel 204 into the sampling tube 301 and is stored above the lifting plate 306. As the urine increases, the lifting plate 306 moves downward under the gravity of the urine, and the lifting plate 306 drives the moving column 305 to move downward. The spring 304 is stretched. After the lifting plate 306 moves downward, the sampling tube 301 is connected to the liquid inlet pipe 602 of the first layer and the rectangular box 601, and the urine enters the rectangular box 601 from the liquid inlet pipe 602 of the first layer. 1 and stored above the rectangular plate 708. With the increase of urine, the rectangular plate 708 moves downward under the gravity of the urine, and the rectangular plate 708 drives the movable column 702 and the fixed rack 703 to move downward together. The spring 1 701 is stretched, and the fixed rack 703 drives the column gear 706 to rotate, and the column gear 706 drives the movable rack 704 to move upward until the movable rack 704 rises to the top of the rectangular box 601, so that the connection between the sampling tube 301 and the rectangular tube can be disconnected, that is, The initial urine can be collected into these two rectangular boxes 601; because the sampling cylinder 301 is disconnected from the first rectangular box 601, as the urine continues to increase, the lifting plate 306 continues to move downward, and when the sampling cylinder 301 is connected to the second-layer liquid inlet pipe 602 and the rectangular box 601, the urine enters the rectangular box 601 from the second-layer liquid inlet pipe 602 and is stored above the rectangular plate 708. As the urine increases, the rectangular plate 708 moves downward under the action of the gravity of the urine, and the rectangular plate 708 drives the movable The column 702 and the fixed rack 703 move downward together, the spring 1 701 is stretched by force, the fixed rack 703 drives the columnar gear 706 to rotate, and the columnar gear 706 drives the movable rack 704 to move upward until the movable rack 704 rises to the top of the rectangular box 601, and the connection between the sampling cylinder 301 and the rectangular tube can be disconnected, and the middle urine can be collected into the two rectangular boxes 601; the subsequent urine will be stored above the lifting plate 306, and the last urine can be stored in the sampling cylinder 301.

[0027] When formaldehyde needs to be added to the urine and shaken for preservation, for the last stage of urine, formaldehyde only needs to be added directly into the sampling tube 301. For the first and middle stages of urine, the rubber stopper 604 needs to be pulled out from the rectangular tube 603, and then formaldehyde needs to be added into the rectangular tube 603. The formaldehyde will enter the T-slot 707 of the movable column 702 and flow out from the T-slot 707 into the urine. Then, the motor 102 is started, and the motor 102 drives the circular plate 103 to rotate. The circular plate 103 drives the upper structure to rotate together, so that the urine in the rectangular box 601 and the sampling tube 301 can be mixed and shaken.

[0028] When it is necessary to sample the midstream urine, the injection head of the disposable syringe only needs to be inserted into the liquid collection port on the fixed cylinder 501. The injection head of the disposable syringe pushes the convex column 502 to move forward, so that the L-shaped groove 504 in the convex column 502 is connected with the inside of the rectangular box 601, so that the midstream urine flows into the L-shaped groove 504, and then the piston of the disposable syringe is pulled backward to extract the midstream urine into the disposable syringe, thereby completing the sampling of the midstream urine.

[0029] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
