Description

Technical Field

[0001] The utility model relates to the technical field of conventional specimen collectors, in particular to a conventional urine specimen collector for preventing false positives in women. Background Art

[0002] Urinalysis is the most commonly used clinical test method. The results of urinalysis can be used to evaluate the functions of the patient's kidneys, ureters, bladder, etc.; it can also provide a reference for the clinical diagnosis of urinary system diseases. However, the accuracy of urine examination is restricted by many factors. Currently, plastic urine cups are used to collect urine in clinical practice. Plastic urine cups are usually placed in the open and are easily contaminated by the environment. When collecting urine, the patient holds the plastic cup in his hand to collect the urine and then pours it into the urine specimen tube. During this process, the urine specimen is easily spilled and contaminated, and it is also easy to dirty the hands. Therefore, we have developed a urinalysis specimen collector to improve this problem. Utility Model Content

DETAILED DESCRIPTION

[0022] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] refer to Figures 1 to 5 :

[0024] Example 1: The utility model discloses a urine specimen collector for preventing false positives in women, comprising a wide-mouthed liquid receiver 1 and a urine receiver 2, wherein the wide-mouthed liquid receiver 1 has an opening 101 that fits the shape of the female perineum. Specifically, the opening 101 has a curved shape with a concave middle portion, and further comprises a flusher 3 and a waste liquid bag 4. The flusher 3 is connected to the wide-mouthed liquid receiver 1 through a liquid inlet pipe 5 extending from one side of the wide-mouthed liquid receiver 1, and a main liquid outlet pipe 6 is extended from the lower end of the wide-mouthed liquid receiver 1, and the lower ends of the main liquid outlet pipe 6 are respectively connected to the urine distribution pipe 7 and the liquid distribution pipe 8, and the lower ends of the liquid distribution pipe 8 are connected to the waste liquid bag 4. The liquid bag 4 is connected, and the end of the urine distribution tube 7 is detachably connected to the urine receiver 2. Specifically, the urine receiver 2 and the urine distribution tube 7 are connected by threaded connection, plug-in connection or abutment. As a preferred embodiment, when a person operates, he directly uses one hand to hold the urine cup to collect urine, but considering that holding the wide-mouthed liquid receiver 1 with one hand may be unstable, a threaded connection can also be used. After the urine receiver 2 reaches a certain scale line, the device can be removed. The main liquid outlet pipe 6 and the liquid distribution tube 8 are controlled by a first control clamp 11. The main liquid outlet pipe 6 and the urine distribution tube 8 are controlled by a second control clamp 12.

[0025] Specifically, the liquid inlet pipe 5 has a bent portion 501, and the end of the liquid inlet pipe 5 passes through the upper end of the wide-mouth liquid receiver 1 and faces the perineum urethra opening, so that during the cleaning operation, a person holds the irrigator 3 with one hand and directly presses the cleaning liquid to spray the cleaning liquid toward the perineum for flushing. Preferably, the flushing liquid can be preferably physiological saline as the flushing liquid. Preferably, the irrigator 3 is a gourd-shaped soft-pack irrigator 3, which has two liquid storage chambers. The irrigator 3 and the liquid inlet pipe 5 are screwed or plugged in. The connection is detachable. Specifically, the liquid distribution tube 8 is located in the same vertical axis direction as the main liquid outlet pipe 6, so that the waste liquid after flushing can fall freely to the waste liquid bag 4. When in use, the flusher 3 filled with flushing liquid can be screwed to the pipe mouth of the liquid inlet pipe 5 through its opening 101 or connected with a hose. Then, the first control clamp 11 at the bottom is opened, and the second control clamp 12 is closed. Press and flush, and then let the waste liquid flow directly vertically to the waste liquid bag 4. After flushing, directly pull out the flusher 3 and proceed to the next step of urination.

[0026] Example 2: On the basis of Example 1, specifically, the technical solution in Example 1, normally most urine collection is to take the middle section, then in the present device of Example 1, if you want to collect the middle section of urine, you need to open the first control clamp 11 first, first discharge a part of the urine into the waste liquid bag 4, then close the first control clamp 11 and open the first control clamp 11 at the same time, and then collect the middle section of urine. Such operation will be a little troublesome. Here, a solution is proposed that can collect the middle section of urine without changing the control clamp back and forth to open and close it. Specifically, a plurality of middle section urine clamping places 801 are provided at the lower part of the liquid separation tube 8 near the waste liquid bag 4. Specifically, a plurality of middle section urine clamping places 801 are distributed in an array on the liquid separation tube 8. The specific clamping position can be determined according to the user's assessment of his or her own urgency of urination, such as the urine itself. If there is less urine, it can be clamped at a position close to the main liquid outlet pipe 6. If there is more urine, it can be clamped at a position close to the waste liquid bag 4. Here, it should be noted that the first control clamp 11 and the second control clamp 12 adopt clip-type control clamps. Because the above-mentioned main liquid outlet pipe 6, liquid inlet pipe 5, liquid distribution pipe 8 and urine distribution pipe 7 are all made of hose materials, they can also be clamped with ordinary clamps. After the first control clamp 11 is clamped in place, the second control clamp 12 is opened. Because the liquid distribution pipe 8 is vertically connected to the main liquid outlet pipe 6, the initial urine will fall into the liquid distribution pipe 8 first. When the liquid distribution pipe 8 is full of the initial urine, the middle urine will be directly discharged into the urine receiver 2 through the urine distribution pipe 7. When it is observed that the urine receiver 2 is about to be full, the device can be removed. With this setting, there is no need to perform unnecessary opening and closing actions on the two control clamps. It can be directly set up in one step.

[0027] Specifically, because the user looks down at the urine collector 2 when using the device, and for ordinary test tubes, the scale is written in the forward direction, that is, upward, which is not conducive to reading the scale in an inverted manner, here, the urine collector 2 is also provided with a scale 201, and the scale 201 is written in an inverted manner from top to bottom, so that the user can confirm the volume scale when lowering his head.

[0028] Specifically, the opening 101 of the wide-mouth liquid receiver 1 is further provided with a soft silicone ring edge 102, which can be easily attached to the perineum to prevent the flushing liquid from spraying out and also prevent damage to the perineal edge tissue.

[0029] Example 3: Reference Figure 5 Specifically, in some cases, during the cleaning stage and the stage where the first-pass urine falls, in some usage situations, such as when the main liquid outlet pipe is bent or has some raised particles inside, it will cause the cleaning liquid or the first-pass urine to splash into the tube opening of the diverter tube, causing a false positive. Here, a solution is proposed, in which a bevel valve 601 is provided between the main liquid outlet pipe and the diverter tube. The bevel valve 601 extends obliquely downward from one side of the right main liquid outlet pipe to the side away from the tube opening of the diverter tube (as seen in the figure, it extends obliquely downward from the upper left to the lower right). In this way, the splashed individual cleaning liquid or first-pass urine can be blocked to prevent false positives. The bevel valve 601 can be produced by injection molding in an integrated manner.

[0030] Continue to refer Figure 5 Specifically, in the method of collecting mid-stream urine in Example 2, when the user's urine falls too fast, when the initial urine falls into the separation tube (blocked by the first control clamp below) and fills the separation tube, some larger urine drops from the middle urine fall into the initial urine, which easily causes mixing. Here, a solution is proposed, in which an anti-backflow valve 801 is provided on one side of the separation tube. The opening direction of the anti-backflow valve 801 is downward and the anti-backflow direction is upward. In this way, since the valve is downwardly opened, it is a one-way opening valve. When in the flushing stage, the flushing liquid can flow downward into the waste liquid bag. When it comes to the urine collection stage, the initial urine will flow downward through the valve and flow into the cavity between the valve and the first control clamp. When the cavity is full, the valve opening will be blocked upward by its buoyancy, preventing the initial urine from flowing upward, so that the falling mid-stream urine can overflow into the separation tube.

[0031] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
