Description

Technical Field

[0001] The utility model relates to the field of urine retention sampling, in particular to a 24-hour urine retention sampling chair. Background Art

[0002] Quantitative detection of 24-hour urine protein is to collect all urine for 24 hours to determine the protein content in it, and then calculate the total amount of protein in 24 hours. It is one of the indispensable examinations for patients with kidney disease and is crucial for the diagnosis of diabetic nephropathy, nephrotic syndrome, etc. The method of collection is to urinate once at a fixed time (such as 8 o'clock) on the first morning, regardless of whether you feel like urinating or not, and discard the urine. After that, each urination is discharged into a fixed container until the next day at this fixed time. Regardless of whether you feel like urinating or not, you urinate once and the urine remains in the container. The container for retaining urine needs to be clean, but it does not necessarily have to be sterilized. Count the total number of milliliters of urine in the container, then mix the urine, and take 20 to 30 milliliters of urine for examination. No preservatives are needed in the urine. For patients, the disadvantages of collecting 24-hour urine are troublesome, time-consuming, inconvenient, and poor accuracy of specimen collection, especially for women, children, and outpatients. It is more difficult to accurately collect 24-hour urine from patients who are critically ill, have oliguria, are in shock, are in coma, or are elderly and frail. Failure to fully shake the urine sample after collecting it, urine concentration or dilution, and excessive activity can all affect the urine protein content, which in turn affects the judgment of clinical physicians.

[0003] After searching, the existing patent CN202221758293.6 discloses a 24-hour urine sample retention chair, including a seat and a sample retention tank, the rear end of the seat is fixedly connected to a backrest, the outer side of the backrest is fixedly connected to an armrest, and the armrest is fixedly connected to the seat through a support foot, a baffle is fitted inside the top groove of the seat, the rear end of the baffle is fixedly connected to a handle, the bottom end of the baffle is fixedly connected to a sealing gasket, the bottom end of the seat is slidably connected to a portable toilet through a slide rail, and the embedded baffle setting facilitates the movement of the seat through the baffle, slider, spring and magnetic sheet, and will not move or deviate at will.

DETAILED DESCRIPTION

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0024] Embodiment 1, as Figures 1 to 3 As shown, the 24-hour urine retention sampling chair includes a seat and a retention device for collecting urine. The seat is composed of a seat cushion 1 and a support leg 3. A backrest 2 is fixedly provided at the rear end of the seat cushion 1. Armrests 4 are symmetrically provided on both sides above the seat cushion 1. The armrests 4 are connected to the seat cushion 1 through the support leg 3. A through hole groove for clamping a portable toilet is provided in the middle of the seat cushion 1. The outer contour of the through hole groove is slightly smaller than the size of the portable toilet. The portable toilet is clamped on the seat cushion 1 through the through hole groove, which is convenient for disassembly and cleaning of the portable toilet. A retention device is provided directly below the seat cushion 1. The retention device is connected to the portable toilet through a funnel 9. In order to facilitate observation of urine in the retention device, the retention device is made of a transparent material, and a scale indicating the volume of the liquid is provided on the outer wall of the retention device.

[0025] like Figure 1As shown, the retention device includes a retention bucket 6 for containing urine and a sealing cover 7 for sealing the retention bucket. The retention bucket 6 is hollow and has an opening at the top. The sealing cover 7 is connected to the upper end of the retention bucket 6 through a connecting piece and can be flipped 180 degrees along the connecting piece. A collecting hole for connecting a funnel 9 is provided in the middle of the sealing cover. A through hole is provided on the outer side of the retention bucket 6, and the stirring sampling device 8 passes through the through hole to enter the interior of the retention bucket 6.

[0026] like Figure 3 As shown, the stirring sampling device 8 includes a rod body 811 and a stirring portion 812. The rod body 811 passes through the through hole on the outside of the retaining bucket 6 and is detachably connected to the stirring portion 812. In order to prevent the stirring device 8 from sliding into the retaining bucket 6 during stirring, the rod body 811 is slightly longer than the height of the retaining bucket 6. The rod body 811 is hollow, and the sampling tube 100 passes through the rod body 811 and enters the interior of the retaining bucket 6. In order to facilitate the measurement of a certain volume, the sampling tube 100 is made of a transparent material, and a scale is set on the outer wall of the sampling tube 100. The sampling tube 100 includes a hose 110 and a suction head 120. One side of the suction head 120 has a thinner tip for accurately controlling the dripping of liquid. The other end of the suction head 120 is connected to the hose 110. A negative pressure suction ball 130 for controlling the flow of liquid is provided on the top of the hose 110. The negative pressure suction ball 130 is slightly larger than the caliber of the hollow rod body 811 to prevent the sampling tube 100 from sliding into the hollow chamber of the rod body 811 when the negative pressure suction ball 130 is squeezed. By squeezing the negative pressure suction ball 130, urine enters the hose 110 through the suction head 120. In order to prevent liquid leakage, the suction head 120 and the hose 110 are integrally formed.

[0027] During use, the user places the retention device directly under the portable toilet, inserts the funnel 9 on the portable toilet into the collection hole of the retention device, and the user sits on the seat cushion 1 and leans on the backrest 2. The urine enters the retention bucket 6 through the funnel 9 of the portable toilet. When sampling is needed, shake the rod body 811, and the rod body 811 drives the stirring part 812 to stir the urine sample in the retention bucket 6 to make the mixed urine more uniform. The sampling tube 100 passes through the rod body 811 and enters the interior of the retention bucket 6. The negative pressure suction ball 130 of the sampling tube 100 is squeezed, and the urine enters the hose 110 through the suction head 120. After multiple squeezing of the negative pressure suction ball 130 to extract urine until the test requirements are met, the sampling tube 100 is pulled out to complete.

[0028] Embodiment 2: This embodiment differs from Embodiment 1 in that it further includes a baffle 912 and a drainage portion 913. Figure 2As shown, in order to prevent urine from being stored in the retention bucket 6 for a long time and causing odor to spread, a drainage portion 913 for guiding urine to flow out is provided at the bottom of the funnel 9. The retained urine is drained through the drainage portion 913 and discharged into the retention bucket 6 from the outlet. The drainage portion 913 is provided in an oblique section shape and is integrally formed with the funnel 9. A baffle 912 is provided at the outlet of the bottom of the funnel 9 to prevent odor from spreading through the funnel. The baffle 912 is rotatably installed at the outlet of the bottom of the funnel 9 through a hinge shaft 911. The baffle 912 is slightly The outlet at the bottom of the funnel 9 is larger than that of the funnel 9. When no urine passes through the funnel 9, the baffle 912 covers the outlet under the action of its own weight. When in use, urine is collected at the outlet of the funnel 9 through the drainage portion 913. The baffle 912 is opened by the weight of the urine and the action of gravity. After the urine is automatically discharged into the retention bucket 6, the baffle 912 covers the outlet under the action of its own weight, thereby blocking the bottom of the funnel 9. Furthermore, a seat cover 5 is provided above the seat cushion 1, and the seat cover 5 is connected to the rear of the seat cushion 1 through a hinge shaft.

[0029] Embodiment 3, this embodiment is different from the previous two embodiments in that a guide collecting plate 200 is provided at the bottom of the retention bucket 6, such as Figure 4 As shown, since the oliguric patient retains less urine for 24 hours, the stirring sampling device does not stir the small amount of urine evenly enough, and since the stirring sampling device passes through the upper side of the outer wall of the retention bucket 6 to enter the interior, the retention sampling device has a certain blind spot when performing stirring sampling. Furthermore, a guide collection plate 200 is provided at the bottom of the retention bucket 6, and the guide collection plate 200 is provided on the same side as the stirring sampling device and at a 45° angle to the bottom of the retention bucket 6. Urine is guided and gathered into a small amount of urine collection area through the guide collection plate 200, and the stirring sampling device passes through the upper side of the outer wall of the retention bucket 6 to enter the small amount of urine collection area, which can better perform stirring sampling.

[0030] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
