Description

Urine protein automatic detection equipment

technical field

The invention relates to the field of medical auxiliary equipment, in particular to an automatic urine protein detection device.

Background technique

There are often various proteins in the blood, and some of the proteins will be filtered into the urine in the kidney spheroids, but will be absorbed in the renal tubules and returned to the blood. Therefore, when the kidneys are functioning normally, urine The amount of protein in the urine is small, but when the kidney and the urinary catheter are obstructed, the function of the renal tubules to absorb protein will become poor, so that more protein will enter the urine, so clinically, it is usually detected by detecting the protein in the urine. Protein content to judge kidney and urinary tract diseases.

At present, the detection of urine protein includes three methods: urine protein qualitative test, urine protein quantitative measurement, and urine protein electrophoresis analysis. Among them, the urine protein qualitative test is usually detected with special test paper for urine protein detection, but this can only show the urine protein during detection. The protein content is easily affected by various factors such as the food eaten by the patient at that time, the physical condition, etc., so the test strip can only make a preliminary judgment. The patient's 24-hour urine volume was collected, and the 24-hour urine was mixed, and then the urine protein content in the mixed urine was detected.

Since the quantitative measurement is performed on 24h mixed urine, in order to improve the accuracy, it is necessary to ensure that the amount of urine collected each time is the same. As a result, the amount of urine collected in a certain time is too much or too little, thereby causing deviations in the test results.

Contents of the invention

The present invention intends to provide an automatic detection device for urine protein, which can automatically quantitatively absorb and store urine, so as to avoid the inability to accurately judge the amount of urine manually and cause deviations in detection results.

In order to achieve the above object, the present invention adopts the following technical scheme: urine protein automatic detection equipment, including a collection unit and a sample retention unit, the collection unit includes a collection bucket and a sealing cover, the bottom of the collection bucket is provided with a drain port, and the sealing cover slides with the collection bucket Connected and used to close the liquid discharge port, the sealing cover is provided with a sampling channel; the sample retention unit includes a driving part, a rotating part, a pushing part and several sampling tubes, the driving part drives the rotating part to rotate, and several sampling tubes are arranged on the rotating part along the circumference and the sampling tube is detachably connected to the rotating part. There is a sampling rod in the sliding seal of the sampling tube. One end of the sampling rod penetrates the sampling tube and is slidably connected with the sampling tube. The cavity is connected with the inner cavity of the sampling tube. The sampling tube is provided with a sampling spring. The two ends of the sampling spring are respectively fixed on the sampling tube and the sampling rod. The rotating part is located under the sampling channel and is used to push the sampling rod upward.

The beneficial effects of this program are:

1. When the pusher is working, the sampling rod can be pushed upwards, so that the sampling rod extends upward into the collection barrel, and while the sampling channel is closed, the inner cavity of the collection barrel is connected with the inner cavity of the sampling tube. When the pusher gradually loosens the sampling rod At the same time, the sampling rod slides into the sampling tube under the action of the sampling spring, thereby sucking the urine in the collection barrel into the sampling tube. Since the inner diameters of the sampling tubes are the same, each sampling tube can inhale the same amount of urine. When mixing urine, there is no need to manually judge the amount of urine, thereby avoiding errors in manual judgment and resulting in deviations in test results.

2. Since the sampling channel is located in the sampling rod, when the urine in the sampling tube is discharged, there will still be a small amount of urine in the sampling tube, which can be stored as a specimen for later verification of the test results or a certain stage. It is used when the urine is tested again to improve the accuracy of the test.

3. At the beginning, the upper end of the sampling rod is located on the upper part of the collection bucket. As the urine is continuously sucked into the sampling tube, the urine in the collection bucket is continuously reduced. reduce, so as to be able to absorb less urine in the collection bucket, and avoid being unable to absorb due to the reduction of urine in the collection bucket.

Further, the sampling tube includes a detection tube at an end away from the pusher, the sampling rod is coaxial with the detection tube and is slidably connected with the detection tube, and the inner wall of the detection tube is fixed with a test paper attached to the side wall of the sampling rod.

The beneficial effect of this solution is: after the sampling rod slides out of the sampling channel, there will still be a small amount of urine remaining on the surface of the sampling rod, which will flow downwards along the sampling rod under gravity, and will continue to gather during the downstream process. The test paper in this solution can absorb urine, avoid the dripping of the pooled urine, and at the same time detect the urine protein in the urine, so as to reflect the urine protein content in each time period. The test paper on multiple sampling tubes can Show changes in urine protein content, thereby assisting doctors in the diagnosis of diseases.

Further, the detection tube is a transparent tube.

The beneficial effect of the solution is that the transparent detection tube will not block the test paper, and the detection result of the test paper can be understood without taking out the test paper.

Further, the sampling channel includes a flared section at the lower end and a constricted section at the upper end, the diameter of the flared section is larger than that of the constricted section, the detection tube is slidably connected to the flared section, and the upper end of the sampling rod is located in the detection tube.

The beneficial effect of this solution is: after the sampling rod slides downward under the action of the sampling spring, the upper end of the sampling rod is located in the detection tube, so as to prevent accidental pressing of the sampling rod and make the urine in the sampling rod leak.

Further, the end of the connecting channel away from the conveyor belt is L-shaped.

The beneficial effect of this solution is: in this solution, when the sampling rod slides into the sampling tube, the connecting passage can be closed by the side wall of the sampling tube, thereby preventing the urine in the sampling tube from splashing out when vibration occurs.

Further, the collection barrel is covered with a cover.

The beneficial effect of this solution is that the cover body can block the urine in the collection barrel, and avoid the urine in the collection barrel from splashing out when the patient accidentally bumps into the device and causes the device to vibrate.

Further, a cleaning pipe is connected to the cover.

The beneficial effect of this scheme is: by connecting the cleaning pipe with the external water pipe, clear water can be passed into the collection bucket, thereby cleaning the collection bucket, avoiding the peculiar smell of urine remaining in the collection bucket for a long time, and also avoiding the urine remaining in the collection bucket. The urine is collected in the bucket and mixed into the urine poured next time, so that the two urines are mixed, resulting in deviations in the detection results.

Further, a heating unit is fixed on the cover or the collection bucket.

The beneficial effect of this scheme is: after the collection bucket is cleaned, water droplets will be attached to the side wall of the collection bucket, and the heating unit can quickly evaporate the water droplets, thereby preventing the clean water from mixing into the urine to be poured next time to dilute the urine, further avoiding detection The results are biased.

Further, the collection barrel is provided with scale marks.

The beneficial effect of this solution is: the patient can judge the amount of urine poured into the collection bucket through the scale line on the collection bucket, so as to avoid too little urine, which will lead to the inability to fill the sampling tube, resulting in mixed urine. The amount of urine in the segment is different, which makes the test results biased.

Further, the sampling tube is slidably connected to the rotating part. A cleaning cylinder and a positioning cylinder are arranged above the rotating part. A cleaning piston and a positioning piston are respectively slid and sealed in the cleaning cylinder and the positioning cylinder. The end of the positioning piston runs through the side wall of the positioning cylinder and connects with the positioning cylinder. The side wall and the sampling channel are slidingly connected; the cleaning piston can be pushed by the sealing cover and the inner cavity of the cleaning cylinder is divided into a cleaning chamber and a pressurization chamber. The side wall of the cleaning chamber is provided with a water inlet and communicated with the cleaning pipe. The rodless cavity of the cylinder is connected; the positioning cylinder or the cleaning cylinder is provided with a return spring to reset the positioning piston.

The beneficial effect of this scheme is: when the pusher pushes the sampling rod upward, the sampling tube can be pushed upward, so after the sampling rod is reset, the upper end of the sampling tube will still remain in the sampling channel, and the sampling channel will be closed. At the same time, When the sampling tube moves laterally with the rotating part, it drives the sealing plate to slide laterally, so that the liquid discharge port is opened, and the residual urine in the collection bucket is quickly discharged.

When the sealing cover slides horizontally, the cleaning piston is pushed to slide, so that the clean water in the cleaning chamber is discharged from the cleaning pipe to clean the collection bucket, and the gas in the booster chamber enters the positioning cylinder, so that the positioning rod of the positioning cylinder extends to the sampling channel Inside, push the sampling rod downwards, so that the sampling tube slides downwards, and at the same time, the sealing cover cannot be reset, prolonging the opening time of the drain port, so as to ensure the discharge of the residual clear water in the collection bucket.
