Description

urine collection device

technical field

The invention relates to the field of medical equipment, in particular to a urine collection device.

Background technique

The urine collection device is one of the most used medical consumables clinically. Patients who are unable to urinate normally due to illness often use catheterization devices. For patients who need long-term bed rest, such as bedridden paralyzed patients or patients with lumbar spine fractures, using catheterization devices can greatly reduce the workload of nursing staff. Complications are also reduced. A general catheterization device includes a catheter for the patient and a urine collection bag for collecting urine. Usually, the nursing staff needs to record the urine output of the patient and collect urine samples to determine the current physical condition of the patient.

Existing urine collection bags are generally made of flexible materials, and the urine collection bags made of flexible materials cannot accurately measure the stored urine due to their own materials, which may cause a difference between the actual urine volume and the measured urine volume. The problem of large interval errors cannot objectively and truly reflect the urine volume, which in turn will affect the diagnosis and treatment of the disease. When collecting urine samples, since the urine collection bag cannot be accurately measured, it can only be measured by the collection container, and the urine flow rate is fast during the collection process, and the liquid level fluctuates greatly, making it difficult to collect accurate urine samples. In addition, when the urine collection bag is used for a period of time to collect a urine sample, since the instant urine is mixed with the urine stored in the urine collection bag, a fresh urine sample cannot be collected, thereby making it impossible to understand the patient's immediate physical condition.

Contents of the invention

The main purpose of the present invention is to provide a urine collection device with accurate measurement;

Another object of the present invention is to provide a urine collection device capable of real-time collection of fresh urine samples.

In order to achieve the above main purpose, the urine collection device provided by the present invention includes a ureter and a urine storage part. The urine storage part is provided with an air outlet and includes a main storage part and a metering part communicated with each other through a first inverted U-shaped tube. The main accommodating part is arranged under the measuring part; the measuring part is a volume-constant container made of transparent hard plastic and communicated with the ureter.

It can be seen from the above solutions that the metering part is a volume-constant container made of transparent hard plastic, so that the urine contained therein can be accurately metered. The metering part communicates with the main container through the inverted U-shaped tube. When the amount of urine in the metering part reaches its rated capacity, the urine in the metering part is introduced into the main container at one time through the inverted U-shaped tube. Therefore, each metering The amount of urine flowing from all parts to the main containing part is its rated capacity, and the urine stored in the urine collecting device can be accurately measured. The working principle of the inverted U-shaped tube will be further described in the example part.

In a more specific solution, the main accommodating part is provided with a first opening and closing valve for discharging the urine contained in the main accommodating part.

Another more specific solution is that the metering part includes a connecting piece connected to the main accommodating part, the first inverted U-shaped tube is installed on the connecting piece, and the connecting piece is provided with a hole for discharging the urine in the metering part to the outside. The second on-off valve is installed on the hole.

When the urine in the metering part reaches the required amount for fresh urine sample collection, the second on-off valve is opened to start the collection. In addition, since the urine in the metering unit reaches its rated capacity, it will all be introduced into the main container at one time, and the metering unit will not store stale urine. Therefore, fresh urine samples are taken out from the metering unit each time. This solution can achieve another object of the present invention.

A more specific solution is that the urine collection device includes a backflow box, the backflow box is arranged between the ureter and the metering part, and the backflow box communicates with the metering part through the second inverted U-shaped tube. When the urine accumulated in the accumulation box reaches its rated capacity, it is introduced into the metering part at one time. When the urine sample is collected from the metering part, the urine does not continuously flow into the metering part but accumulates in the accumulation box, so that the amount of urine collected from the metering part is more accurate.

A more specific solution is that an overflow pipe is provided on the accumulation box, the upper end of the overflow pipe is located in the accumulation box, and the lower end is located in the metering part. In order to prevent the patient from excessive urine volume in a short time, the second inverted U-shaped tube is limited by its inner diameter and cannot be discharged in time, so that when the urine volume in the accumulation box exceeds its rated capacity, it can flow into the metering part from the overflow tube.

A more specific solution is that an air duct is provided in the accumulation box, the upper end of the air duct is located in the accumulation box and is higher than the upper end of the overflow pipe, and the lower tube of the air duct is located in the metering part. Use the air guide tube to lead out the air in the metering part, and flow out from the air outlet.

Yet another more specific solution is that the main receiving part is made of a flexible film.

A more specific solution is a support, the support is fixedly connected to the metering part, and the upper part of the main accommodating part is supported on the support.

The support member is used to support the flexible membrane, which can protect the main accommodating part.

A more specific solution is that the supporting member is configured as two buckle-engaged pressure strips, and the upper edge of the main accommodating part is clamped between the two pressure strips.

The main accommodating part 3 is in sealing connection with the outer wall of the hole 231 and the outer wall of the valve 32. The valve core of the valve 32 is provided with a hole. When the hole overlaps with the hole 322 of the valve 32, the valve 32 is in an open state, and when the valve core moves When the hole does not coincide with the hole 322 completely, the valve 32 is in a closed state.

As shown in Figure 3, two holes 211 and 212 are provided on the connecting cover 21, wherein the hole 211 is connected with the ureter 1, and the hole 212 is an air outlet, and a sealing plug (not shown) is provided on the connecting cover 21 to open and close Vent 212. The bottom of the accumulating box 25 is provided with a card slot that is engaged with the clip 261, so that the accumulating box 25 is fixed in the neck 24 of the metering part 2, and the nozzle 254 of the tube 251 is higher than the inner bottom surface of the accumulating box 25 , the other nozzle 255 extends into the metering portion 2 through the bottom wall of the accumulation box 25 .

When the liquid level of urine stored in the accumulation flow box 25 was higher than the turning point of the inner cavity of the pipe 251, the urine flowed from the nozzle 254 to the metering part 2 through the nozzle 255, and due to the siphon effect, the liquid in the accumulation flow box 25 The urine flows out through the pipe 251 continuously until the urine in the accumulation flow box 25 runs out. In the present embodiment, the rated capacity of the accumulation box 25 is set to 6 milliliters, that is, when the amount of urine contained in the accumulation box 25 exceeds 6 milliliters, its liquid level will cross the top of the inner cavity of the tube 251, thereby making the urine accumulation volume more than 6 milliliters. The urine in the flow box 25 flows to the metering unit 2 . It can be understood that the rated capacity of the accumulating flow box 25 can be reasonably designed according to medical needs, its shape and the height of the turning point of the tube 251, and is not limited to 6 milliliters.

As shown in Figure 4, the support member is made of a fixed bead 311 and two movable bead 312, wherein the movable bead can rotate around the plastic hinge 315, the fixed bead 311 is provided with a protrusion 313, and the movable bead is provided with a hole 314. The upper part of the main accommodating part is provided with a hole, when the support member is connected with the main accommodating part, the movable bead 312 is opened first, the protrusion 313 on the fixed bead 311 passes through the hole of the main accommodating part, and then the movable bead 312 is closed to make the protrusion 313 passes through the hole 314 and snaps together to connect and fix the main accommodating part with the supporting member.

When the urine collection device is in use, first check that the valves 233 and 32 should all be in the closed state, and the pipeline locking device on the ureter 1 should also be in the state that makes the ureter non-conductive. Select an appropriate hanging position, and hang the urine collection device at a position not higher than the patient's bed surface through the hook 221. It is better to be lower than the bed surface height. If there is a beam, it can be hung on the beam. Any of the various uprights that are closer to the patient. After the urine collection device is hung up, the connecting plug 11 is connected with the patient's urinary catheter, checks whether the air outlet 212 is opened, and then opens the sealing plug if it is closed by the sealing plug. Then, the pipe locking device is opened to allow urine to enter the accumulation flow box 25 from the ureter 1 through the hole 211, and the urine collection device starts to work. When the urine in the accumulation flow box 25 reaches its rated capacity, that is, 6 milliliters, the tube 251 is turned on and the urine in the accumulation flow box 25 is introduced into the metering part 2 at one time, and the air in the metering part 2 passes through the guide. The air pipe 252 is discharged to the top of the flow box 25 and then discharged through the air outlet 212 . When the patient's urine volume is too large and the discharge speed of the pipe 251 is too slow so that the urine in the accumulation box 25 exceeds its rated capacity, the urine can flow from the overflow pipe 253 to the metering portion 2 . After the urine in the accumulation box 25 is completely introduced into the metering part 2, as the patient's urine is continuously introduced from the ureter 1, the next flow cycle of the accumulation box 25 begins.

When the stored urine of the metering part 2 reaches its rated capacity of 500 milliliters, the tube 26 is turned on, and 500 milliliters of urine is led to the main containing part at one time. Although the flexible material that main accommodation part 3 adopts is made, its capacity measurement may have larger error, but the amount of urine that imports from metering part 2 every time is all accurate 500 milliliters, and the urine in main accommodation part 3 is still Can be accurately measured. Such an uninterrupted cycle until the use time of the urine collection device reaches the set time, such as 24 hours, close the pipeline locking device, at this time, the urine volume in the metering part 2 is added to the urine volume in the main container part 3, i.e. is the patient's 24-hour urine output.

When it is necessary to collect a fresh urine sample, open the valve 233 to extract it from the metering part 2 . Since the urine in the metering part is introduced into the main storage part at one time, and no urine remains, what is collected from the metering part 2 is a fresh urine sample. The metering part 2 is made of transparent hard plastic, and its capacity error is very small, and can be accurately read from the scale marked on the metering part 2, and then the amount of urine sample collected can also be accurately calculated without using a collection container for metering. In addition, when collecting a urine sample from the metering part, the urine does not flow continuously from the ureter 1 into the metering part 2 but accumulates in the accumulation box 25, and the amount of urine in the metering part generally does not change during the collection process. Therefore, the amount of urine sample collection is further made more accurate. The best time to collect a fresh urine sample is when the urine collecting device is just used, or the sample after the metering part 2 has been emptied for one time. After the collection work is finished, the valve 233 is closed, and the urine sample volume is recorded.

The above is the preferred embodiment of the present invention, and the present invention includes but is not limited thereto. If there is a gap between the accumulating flow box and the neck of the metering part and no air duct is provided, the upper part of the main accommodating part may not be provided with a hole but clamped by two pressure bars Fixed, the main accommodating part can also be made of transparent hard materials, etc., and all technical solutions that adopt equivalent transformation methods all fall within the protection scope of the present invention.
