Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a 24-hour urine protein constant temperature device. Background Art

[0002] The test results of 24-hour urine specimens are commonly used indicators for the clinical diagnosis of diseases such as kidney disease and diabetes. It is usually necessary to collect a 24-hour urine specimen from the patient. The tests include urine sugar quantification, urine protein quantification, urine ion quantification, etc. To test the 24-hour urine specimen, you first need a suitable collection container to accurately collect the patient's 24-hour urine.

[0003] At present, in clinical practice, a clean plastic bucket with appropriate capacity is usually used to collect the patient's urine from 7 am to 7 am the next morning, and the plastic bucket is shaken or the urine is stirred with a stirring rod at 7 am the next morning. Then the bucket lid is opened and a small amount of the shaken urine is extracted with a syringe for inspection. This operation has the following defects: 1. Urine protein is easy to precipitate on the bottom of the measuring cup. During the external shaking or internal stirring of the urine sample, improper shaking or insufficient shaking by medical staff will affect the test results; 2. When stirring the urine sample, if the stirring rod is not fully sterilized, it may cause contamination to the urine sample and affect the test results; 3. When observing the total amount of urine in the plastic bucket or stirring and sampling the urine, the liquid surface of the urine is in an open state, which will cause pollution to the surrounding environment and staff.

[0004] In order to solve the above technical problems, the technical solution of the Chinese utility model patent announcement with patent application number CN202022775903.0 is a 24-hour urine protein quantitative retention and collection device, including a measuring cup, a cup cover, a fixed cylinder, a sampling tube, a stirring rod and a reset piece; the cup cover is arranged at the top of the measuring cup; the fixed cylinder passes through the through hole of the cup cover and extends into the measuring cup, and the end of the fixed cylinder is embedded in the cup cover groove; the sampling tube passes through the fixed cylinder; the stirring rod is circumferentially arranged on the outer wall surface of the bottom end of the sampling tube; the reset piece is arranged in the corresponding bottom groove of the sampling tube, and the two ends of each reset piece are fixed by a clamping block, and one side of the reset piece is in contact with the stirring rod clamping groove. The utility model has the functions of storing urine, uniformly stirring urine before sampling and sampling urine, and the device has strong functionality and high usability.

[0005] However, the above-mentioned prior art has the following technical problems: the above-mentioned 24-hour urine protein quantitative retention and collection device cannot adjust the temperature of the urine sample stored in the measuring cup, and the urine protein needs to be refrigerated at a temperature of 2 to 8°C, otherwise the urine protein will denature when exposed to heat, and medical staff will not be able to obtain accurate test results for the patient. In order to ensure that the urine protein will not denature when exposed to heat, the urine sample is usually refrigerated in a refrigerator or locker at 8°C. However, when collecting the patient's 24-hour urine sample, the patient needs to take the container storing the urine sample out of the refrigerator or locker after each urination, and pour the new urine sample into the container storing the urine sample, and then put the container storing the urine sample into the refrigerator or locker. This process will be repeated many times, which is very inconvenient. In addition, when the weather is hot, if the urine sample is not refrigerated in the refrigerator or locker in time, the urine protein in the urine sample will denature when exposed to heat, resulting in inaccurate test results for the patient's urine sample.

The control terminal 43 is electrically connected to the temperature sensor and the temperature control component 41 respectively. The temperature sensor is used to transmit the detected temperature data to the control terminal 43. The control terminal 43 is used to control the temperature control component 41 to cool down and reduce the temperature of the insulation barrel 20 when the temperature data is higher than the preset temperature. The control terminal 43 is also used to control the temperature control component 41 to heat up and increase the temperature of the insulation barrel 20 when the temperature data is lower than the preset temperature. In this way, the temperature in the insulation barrel 20 can be maintained at 2 to 8°C, ensuring that the urine sample contained in the measuring cylinder 30 will not be denatured by heat, so that the urine sample does not need to be refrigerated in a refrigerator or locker.
