Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of medical consumables, and particularly relates to a rapid quantitative collection and storage device for indwelling urine specimen. BACKGROUND

[0002] In clinical practice, 24-hour urine can be used to determine the total amount of various substances excreted by the patient's kidney in 24 hours, such as quantitative detection of urine protein, uric acid, electrolytes, etc. Generally, the urine is discharged at 7 o'clock in the morning, and all the urine in the next 24 hours is collected, and the patient must urinate and collect at 7 o'clock in the morning on the second day.

[0003] For example, rheumatic diseases, especially systemic lupus erythematosus and systemic vasculitis, often involve the kidneys and cause hematuria and proteinuria, which are important markers of kidney involvement. Generally, urine protein is detected and treated effectively, and specialist doctors often judge the efficacy and adjust the medication according to the increase and decrease of urine protein.

[0004] It is particularly important to collect urine samples correctly.

[0005] 1. Collection time of urine: Any time of urine discharge can be used for routine laboratory examination. Generally, kidney patients are required to send the first morning urine for examination to observe the results before and after.

[0006] 2. The amount of urine sent for examination: Generally 5-10ml, if specific gravity is to be measured, it should not be less than 50ml.

[0007] 3. The urine specimen should be taken from the middle segment: first, a part of the urine is discharged and discarded to flush away the bacteria in the urethral orifice and the anterior urethra, and then the middle segment urine is collected and sent for examination. Attention should be paid to not mixing non-urine components into the urine: such as female patients should not mix leucorrhea and menstrual blood (menstrual period does not advocate routine urine test), and male patients should not mix prostatic fluid, etc.

[0008] Among them, the quantitative urine specimen is more troublesome. In clinical practice, the required urine volume is measured by a measuring cup, mixed, and about 10ml is taken for examination. During the process of taking urine with the measuring cup, on the one hand, the collected amount is not accurate, and on the other hand, the urine is easy to splash on the operator's hand during the process of determining the collected amount, causing contamination and discomfort to the operator. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0029] The application provides a fast quantitative collection and storage device for indwelling urine specimen, which comprises a negative pressure suction 1, a storage cylinder 2 and a bottom storage 3. The negative pressure suction 1 is detachably buckled at the top end of the storage cylinder 2, and the bottom storage 3 is detachably buckled at the bottom of the storage cylinder 2, so as to form a device integrated with collection and storage. The negative pressure suction 1 provides a negative pressure environment, and urine is extracted through the storage cylinder 2 to complete specimen collection. Meanwhile, the outer surface of the storage cylinder 2 is provided with a scale 4, so that quantitative extraction can be realized in the sampling process, direct extraction amount determination can be completed, and the method is accurate, fast and less likely to emit peculiar smell.

[0030] Example 1

[0031] Based on the above, the application provides a preferred negative pressure suction 1 structure, so as to cooperate with the storage and the bottom storage 3 and complete stable and effective suction of urine specimen.

[0032] Specifically, in this embodiment, the negative pressure suction cap 1 includes a balloon 12 and a snap-fit ​​cap. The top of the balloon 12 is provided with a normally open outward one-way valve 11. When the balloon 12 is repeatedly squeezed, the gas inside the balloon 12 overflows from the one-way valve 11 without excessively squeezing the urine sample at the bottom, causing the urine sample to overflow from the bottom of the storage cylinder 2. The snap-fit ​​cap includes a protruding inner cylinder 14, and an annular groove 15 is provided between the inner cylinder 14 and the snap-fit ​​cap body. The annular groove 15 is used to snap the storage cylinder 2, and the inner cylinder 14 is used to snap the bottom storage 3, thus constructing two different forms of urine storage in this utility model.

[0033] To enhance the negative pressure suction of the balloon 12, a metal spring 13 is provided on the inner side of the balloon 12 in this embodiment. The metal spring 13 is closely attached to the inner side of the balloon 12 to provide support for the shape recovery of the balloon 12, so as to ensure stable suction during urine collection.

[0034] Example 2

[0035] Based on the above embodiment 1, in order to avoid urine sample flowing down during repeated squeezing of the balloon 12, this embodiment provides a preferred structure for the storage cylinder 2 to cooperate with the balloon 12 to complete repeated squeezing and suction.

[0036] Specifically, in this embodiment, the negative pressure suction cap 1 and the storage cylinder 2, when fastened together, form the urine suction body. The bottom of the storage cylinder 2 is a slender suction section 21, and above the suction section 21 is a straight cylinder 25. The suction section 21 and the straight cylinder 25 are connected by a funnel-shaped transition section 24. The slender suction section 21 has a small cross-section, resulting in a relatively high surface tension of the urine fluid as it flows downward through this channel, increasing the resistance to the downward flow of urine. Based on this, a filter screen 22 is provided inside the suction section 21 to prevent the intake of impurities. The transition section 24 and the straight cylinder 25 are provided with a partition 23, which is sealed on one side and has a gap on the other side, forming a meandering flow path. During normal suction, urine needs to be injected upward into the storage cylinder 2 along the meandering channel. Under the action of the metal spring 13, there is sufficient attraction to draw the urine into the storage cylinder 2. When the urine is left to stand, it is difficult for it to break through the meandering path and the slender suction section 21 and flow downward under its own gravity. In conjunction with the one-way valve 11 on the upper part of the balloon 12, urine will not flow out excessively when the balloon 12 is squeezed again, thus achieving repeated suction.

[0037] Example 3

[0038] Based on the above embodiment 1, this embodiment provides two forms of urine storage.

[0039] In this embodiment, the inner cylinder 14 of the negative pressure suction cap 1 is a flexible structure that can be directly inserted into the top temporal part of the storage cylinder 2 or into the top of the bottom storage 3.

[0040] Storage mode 1: negative pressure suction nozzle 1 is buckled on the top of storage cylinder 2, bottom storage 3 is buckled on the bottom of storage cylinder 2, and the storage main body is formed, and the amount of stored urine sample can be observed in real time through scale 4.

[0041] Storage mode 2: negative pressure suction nozzle 1 is buckled on the top of bottom storage 3, and urine sample is stored in bottom storage 3, and the structure is small in size, and it is convenient to detect the collected urine again.

[0042] In order to avoid the urine from storage cylinder 2 from overflowing under the action of external force in storage mode 1, and to avoid the urine from overflowing excessively to balloon 12 in storage mode 2, in the embodiment, elastic film 32 is arranged on the top of bottom storage 3 and used for sealing bottom storage 3, a circular through hole is arranged in the middle of elastic film 32 and used for facilitating suction part 21 to pass through, and rubber pad 31 is arranged on the bottom of bottom storage 3, suction part 21 is abutted against rubber pad 31 when storage cylinder 2 is buckled on bottom storage 3, and sealing is completed.

[0043] In conclusion, the sampling device can quickly and accurately collect the indwelling urine quantitatively, meanwhile, the situation of causing discomfort to operators caused by ectopic return odor and the like is avoided. Meanwhile, the device can extract samples and store urine, simplifies urine collection tools, improves efficiency, and avoids secondary transportation of samples.
