 Urine collection device

The invention relates to the field of medical instruments, in particular to a urine collecting device. The present invention is based on the Chinese Patent Application No. 201210199826.6, filed on Jun. 15, 2012, the content of which is hereby incorporated by reference.

The urine collecting device is clinically one of the medical consumables with a large amount of use. The use of catheterization devices is often used in patients who are unable to urinate normally due to illness, and the use of catheterization devices can greatly reduce the work intensity of caregivers for patients who are bedridden or patients with lumbar vertebrae fractures who require prolonged bed rest. It can also reduce complications. A general catheterization device includes a catheter for indwelling a patient and a urine collection bag for collecting urine. Usually, the nursing staff needs to record the patient's urine output and collect urine samples to determine the current physical condition of the patient.

The existing urine collection bag is generally made of a flexible material, and the urine collection bag made of a flexible material cannot accurately measure the stored urine due to its own material, and may generate actual urine volume and measured urine volume. The problem of large error can not objectively and truly reflect the amount of urine, which in turn will affect the diagnosis and treatment of the disease. When the urine sample is collected, since the urine collection bag cannot be accurately metered, it can only be measured by the collection container, and the urine flow rate is faster during the collection process, the liquid surface is fluctuating greatly, and it is difficult to collect a precise amount of the urine sample. In addition, when the urine collection bag is used for a period of time, when the urine sample is collected, the urine is stored in the urine collection bag, and the fresh urine sample cannot be collected, so that the immediate physical condition of the patient cannot be understood.

The main object of the present invention is to provide a metering and accurate urine collecting device;

Another object of the present invention is to provide a urine collection device that enables instant collection of fresh urine samples.

In order to achieve the above main object, the urine collecting device provided by the present invention comprises a ureter and a urine containing portion, the urine receiving portion is provided with an air outlet hole and includes a main receiving portion and a metering portion that communicate with each other through the first inverted U-shaped tube. The main accommodating portion is disposed below the metering portion; the metering portion is a constant volume container made of transparent hard plastic and is in communication with the ureter.

A more specific solution is provided with a first opening and closing valve for the main accommodating portion for discharging the urine in the main accommodating portion.

Another more specific solution is that the metering portion includes a connecting member connected to the main receiving portion, the first inverted U-shaped tube is mounted on the connecting member, and the connecting member is provided with a hole for discharging urine in the measuring portion to the outside, and A second opening and closing valve is mounted on the hole.

When the urine in the measuring unit reaches the required amount of fresh urine sample collection, the second opening and closing valve is opened to perform the collection. In addition, since the urine in the measuring unit is completely introduced into the main accommodating portion once it reaches its rated capacity, the measuring unit does not store the old urine, and therefore, each time it is taken out from the measuring unit, it is a fresh urine sample. This solution can achieve another object of the present invention.

A more specific solution is that the urine collection device includes a current collecting box disposed between the ureter and the metering portion, and the current collecting box is in communication with the metering portion through the second inverted U-shaped tube. When the urine accumulated in the accumulating box reaches its rated capacity, it is once introduced into the metering unit. When the urine sample is collected from the metering unit, the urine does not continuously flow into the metering portion but accumulates in the pool box, so that the amount of urine collected from the metering portion is more accurate.

A more specific solution is to provide an overflow pipe on the current collecting box, the upper end of the overflow pipe is located in the current collecting box, and the lower end is located in the measuring portion. In order to prevent the patient's short-term urine volume from being too large, the second inverted U-shaped tube is limited by its inner diameter and cannot be discharged in time, so that the amount of urine in the pool box exceeds its rated capacity, and can flow from the overflow tube into the metering portion.

A more specific solution is that an air guiding tube is disposed in the current collecting box, and an upper end of the air guiding tube is located in the current collecting box and has a height higher than an upper end of the overflow tube, and a lower tube of the air guiding tube is located in the measuring portion. The air in the metering section is led out by the air duct and flows out from the air outlet.

Yet another more specific solution is that the main receptacle is made of a flexible membrane.

More specifically, the support member is fixedly connected to the metering portion, and the upper portion of the main housing portion is supported on the support member.

Supporting the flexible membrane with the support member can serve to protect the main receptacle.

More specifically, the support member is provided as two detachable beads, and the upper edge of the main accommodating portion is sandwiched between the two embossing strips.

It can be seen from the above scheme that the metering part is a constant volume container made of transparent hard plastic, so that the urine contained therein can be accurately metered. The measuring unit communicates with the main accommodating portion through the inverted U-shaped tube. When the amount of urine in the measuring portion reaches its rated capacity, the urine in the measuring portion is introduced into the main accommodating portion at one time through the inverted U-shaped tube, so each measurement is performed. The amount of urine flowing to the main accommodating portion is its rated capacity, and the urine stored in the urine collecting device can be accurately measured. The working principle of the inverted U-tube is further explained in the section of the embodiment.

When the urine collecting device is used, the first inspection is performed, and the valves 233 and 32 should be in a closed state, and the pipe locking device on the ureter 1 should also be in a state in which the ureter is not electrically connected. Select the appropriate hanging position, and hang the urine collecting device at a position not higher than the patient's bed surface through the hook 221, which is better than the height of the bed surface, and the beam can be hooked on the beam, and the beam can be hung on the beam without the beam. Any column that is closer to the patient. After the urine collecting device is hung, the connecting plug 11 is connected to the patient's catheter, and it is checked whether the air outlet 212 is opened, and if it is closed by the sealing plug, the sealing plug is opened. Then, the pipe locking device is opened to allow urine to enter the pool box 25 from the ureter 1 through the hole 211, and the urine collecting device starts to enter the working state. When the urine in the header 25 reaches its rated capacity, that is, 6 ml, the tube 251 is turned on and the urine in the pool 25 is introduced into the metering unit 2 at a time, and the air in the metering unit 2 is guided. The air tube 252 is discharged above the accumulation box 25 and then discharged through the air outlet 212. When the urine volume of the patient is too large and the discharge speed of the tube 251 is too slow to cause the urine in the accumulation box 25 to exceed its rated capacity, the urine can flow from the overflow tube 253 to the metering portion 2. When the urine in the current collecting box 25 is completely introduced into the measuring unit 2, the next flow cycle of the integrated flow box 25 is started as the patient's urine is continuously introduced from the ureter 1.

When the stored urine of the metering section 2 reaches its rated capacity, i.e., 500 ml, the tube 26 is turned on, and 500 ml of urine is introduced into the main housing at one time. Although the main accommodating portion 3 is made of a flexible material, the capacity measurement thereof may have a large error, but the amount of urine introduced from the measuring portion 2 is accurate 500 ml at a time, and the urine in the main accommodating portion 3 is still Can be accurately measured. Such an uninterrupted cycle until the urinary device has reached the set time, such as 24 hours, the pipe locking device is closed, and the amount of urine in the metering portion 2 is added to the amount of urine in the main accommodating portion 3, that is, It is the patient's 24-hour urine output.

When it is necessary to collect a fresh urine sample, the valve 233 is opened and extracted from the measuring unit 2. Since the urine in the measuring unit is introduced into the main accommodating portion at one time, and no urine remains, the fresh urine sample is collected from the measuring unit 2. The metering section 2 is made of transparent hard plastic, and its capacity error is very small, and can be accurately read out from the scale marked on the metering section 2, and the amount of the urine sample collected can also be accurately calculated without using the collecting container for metering. In addition, when the urine sample is collected from the metering unit, the urine does not continuously flow from the ureter 1 into the metering unit 2 but accumulates in the pool box 25. The amount of urine in the metering unit generally does not change during the collection process. Therefore, the amount of collected urine samples is further made more precise. The best time to collect fresh urine samples is when the urine collection device is just used, or the sample after the metering unit 2 is emptyed at one time. After the end of the collection work, the valve 233 is closed and the amount of urine sample is recorded.

The above is a preferred embodiment of the present invention. The present invention includes but is not limited thereto. For example, there is a gap between the current collecting box and the neck of the metering portion without providing an air guiding tube, and the upper portion of the main receiving portion may be not clamped but clamped by two pressure strips. The main receiving portion can also be made of a transparent hard material, etc., and any technical solution using an equivalent conversion method falls within the protection scope of the present invention.

The measuring unit communicates with the main accommodating portion through the inverted U-shaped tube. When the amount of urine in the measuring portion reaches its rated capacity, the urine in the measuring portion is introduced into the main accommodating portion at one time through the inverted U-shaped tube, so each measurement is performed. The amount of urine flowing to the main accommodating portion is its rated capacity, and the urine stored in the urine collecting device can be accurately measured.
