technical field

The utility model relates to a medical inspection auxiliary appliance, in particular to a urine collection device for automatically intercepting middle-section urine.

Background technique

Most of the medical urine sampling devices currently used in hospital inspections are disposable cups, or a disposable cup plus a test tube, which has the following defects in actual use: the existing urine sampler directly imports urine into the test tube through a catheter, But in fact, part of the urine at the beginning of urination is front-end urine, which is not suitable for urine sample testing, that is, part of the front-end urine is also introduced into the test tube for testing, resulting in an inaccurate test structure.

Contents of the invention

Aiming at the above-mentioned shortcomings of the prior art, the utility model provides a urine collection device that automatically intercepts the middle urine, which can remove the urine at the front end in the initial stage to ensure the accuracy of the test results.

A urine collection device for automatically intercepting mid-section urine, comprising a urine cup, a catheter, and a test tube, the urine cup includes a urine cup body with an open upper end, a partition is provided in the middle of the urine cup body, and the partition divides the urine cup body It is two connected cavities up and down, the cavity at the lower part is the front-end urine cavity, the overflow port connecting the upper and lower cavities is set on the partition, the side wall of the urine cup body is provided with a middle urine cavity, and the urine cup body The side wall is provided with a liquid inlet that connects the urine cup body with the middle urine chamber, the liquid inlet is located above the overflow port, the middle urine chamber is equipped with a piston, the middle urine chamber is connected to the test tube through a catheter, and is pushed by the piston The method realizes that the urine is pressed into the catheter from the urine cavity in the middle, and then enters the test tube.

Further, the piston is a liquid pushing plate with a push rod, and the shape of the liquid pushing plate matches the cavity shape of the middle urine cavity.

Further, the urine cup body is a bucket-shaped structure with a wide top and a narrow bottom.

Further, the volume of the urine cavity at the front end is 40-100ml.

Further, it also includes a test tube cover that can seal the test tube mouth. The test tube cover includes an inner plug that can be inserted into the test tube opening and a lid hinged with the inner plug. The inner plug is a hollow structure, and the cover extends into the hollow part of the inner plug. A seal is formed, and air holes are provided on the cover.

Further, the cover body protrudes inwardly with a fixing column that can be sleeved with the catheter, and the front end of the fixing column is provided with a reboundable rebound cover.

The utility model can collect the waste urine in the early stage of urination by setting the front end urine cavity at the bottom formed by the interval of the baffle in the urine cup, and the urine that really needs to be collected flows into the catheter through the overflow port, and finally enters the test tube , so as to remove the front-end urine in the initial stage to ensure the accuracy of the test results.

detailed description

The technical solution in the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the utility model.

Please refer to Fig. 1, the embodiment of the urine collection device for automatically intercepting the middle urine of the present invention includes a urine cup 1, a catheter 2, and a test tube 3, and the urine cup 1 includes a urine cup body 11 with an open upper end, and the urine cup body 11 is A bucket-shaped structure with a wide top and a narrow bottom. The middle part of the urine cup body 11 is provided with a partition 12, which divides the urine cup body 11 into two connected cavities up and down. Body connected overflow port 13.

The upper part of the side wall of the urine cup body 11 is provided with a middle section urine cavity 14, and the side wall of the urine cup body 11 is provided with a liquid inlet 15 that the urine cup body 11 is communicated with the middle section urine cavity 14, and the middle section urine cavity 14 can be Barrel-shaped structure, the middle urine chamber 14 is provided with a liquid pushing plate 16 with a push rod 17 , the shape of the liquid pushing plate 16 matches the cavity shape of the middle urine chamber 14 . The liquid inlet 15 is located above the overflow port 13, and the middle urine chamber 14 is connected to the test tube 3 through the catheter 2. Specifically, one end of the catheter 2 communicates with the middle urine chamber 14, and the other end is detachably connected to the test tube 3.

When in use, the urine flows into the urine cup body 11, and the urine at the initial stage will flow into the front-end urine chamber 18 through the overflow port 13 of the partition 12 for temporary collection. The volume of the front-end urine chamber 18 can be set according to the actual situation , the present embodiment is set to 40-100ml, so about 40-100ml of front-end urine is collected in the front-end urine cavity 18, and subsequent urine will accumulate in the urine cavity after the front-end urine cavity 18 is filled with front-end urine. The cup body 11 flows into the middle urine chamber 14 through the liquid inlet 15, and finally enters the test tube 3 through the catheter 2. Compared with the prior art, the urine at the front end in the initial stage can be removed to ensure the accuracy of the test results.

The utility model also includes a test tube cover 4 that can seal the mouth of the test tube 3. The test tube cover 4 includes an inner plug 41 that can be inserted into the mouth of the test tube 3 and a cover body 42 that is hinged with the inner plug 41 through a hinge 47. The inner plug 41 is Hollow structure, the cover body 42 extends into the hollow part of the inner plug 41 to form a seal. The cover body 42 protrudes inwardly with a fixing column 45 that can be socketed with the catheter 2 , and a resilient rebound cover 43 is provided at the front end of the fixing column 45 . It is in a closed state under normal conditions, and it is held open by the front end of the catheter 2 when collecting the middle urine. There are many ways to realize the stability of the inner urine sample. As shown in FIG. 2 , a revolving spring 44 is provided at the connection between the resilient cover 43 and the inner plug 41 . The cover 42 is provided with an air hole 46 to facilitate the smooth flow of urine from the catheter 2 into the test tube 3 . The outer wall of the test tube 3 is provided with a scale, which can facilitate and accurately collect the amount of urine.

The working principle of this embodiment: as shown in Figure 2, firstly, the urine cup 1 is inserted into the test tube cover 4 through the catheter 2, so that the outlet end of the catheter 2 extends into the test tube 3, and after the urine cup 1 catches the urine, the front end of the urine cup 1 The liquid flows into the front end urine cavity 18 of the bottom of the urine cup 1, and the effective urine overflows from the overflow port 13 of the dividing plate 12 and then enters the middle urine cavity 14 through the liquid inlet 15, and then automatically flows into the test tube 3 through the catheter 2, if If the urine volume in the middle urine cavity 14 is insufficient (for example, middle-aged and elderly patients or children), push the liquid pushing plate 16 downwards through the push rod 17, so that the urine pressure in the middle urine cavity 14 enters the catheter 2, and then enters the test tube 3 Inside. After collecting, the catheter 2 is extracted from the test tube 3 (ie, pulled out from the fixed post 45 of the cover body 42), and after the catheter 2 is pulled out, the rebound cover 43 automatically rebounds and seals, and can be sent for inspection.
