Description

Negative pressure backflow urine bag

The present invention relates to a backflow prevention urine bag, and more particularly to a negative pressure backflow urine bag.

Patients who are generally unable to urinate on their own (eg, during or after surgery) or people with disabilities usually use a urine bag. Conventional urine bags are mainly composed of a catheter having opposite ends and a urine bag body communicating with the catheter. One end of the catheter is connected to the urethra of the patient, and the other end is connected to the body of the urine bag.

Although the urinary catheter of the existing urine bag is mainly used for draining urine accumulated in the bladder of the patient. However, the above-mentioned drainage is not only simple urine, but it is often accompanied by hematuria, postoperative small stones, various pus or sediments that easily cause urinary tract infections. Once the horizontal position of the bag body is too high (eg, higher than the patient's bladder position) or is not squeezed, the urine, hematuria, postoperative small stones stored in the bag body, Various pus or sediments that easily cause urinary tract infections can easily flow back into the urethra of the patient along the urinary catheter, which can lead to obstruction of the urinary catheter, which in turn causes the patient's urethra to be invaded by bacteria, mold or other microorganisms. Cause urinary tract infection (hereinafter referred to as UTI). The most common are those such as cystitis or urethritis. More seriously, once the infected area spreads upward, it will invade the kidney's own tissue to cause pyelonephritis. Therefore, the existing urine bag is the most disadvantaged of the medical profession, mainly because the catheter is an open tube, which not only makes the patient have a tube blockage problem due to urine reflux, but also easily causes the patient to cause UTI problems. .

In order to solve the above problems, those skilled in the art dispose of components such as valves or one-way valves in the catheter to force the urine drained from the patient's urethra to flow through the aforementioned valve or one-way valve. After that, it can no longer flow back to the urethra. The aforementioned technical means of backflow prevention can be found in the one-way drainage continuous urine bag disclosed in the new patent case of the Republic of China No. TWM440105 certificate number, or the improved urine bag disclosed in the new patent case of the Republic of China No. TWM498005 certificate number.

According to the above description, improving the anti-reverse bag to reduce the clogging of the catheter and reducing the UTI risk of the patient is a subject to be solved by those skilled in the art.

Accordingly, it is an object of the present invention to provide a negative pressure backflow urine bag that avoids clogging of the tubing to reduce the risk of UTI in the patient.

Therefore, the novel negative pressure anti-backflow urine bag comprises a bag body, a drainage tube, a negative pressure unit, and a backflow prevention valve unit.

The negative pressure unit is disposed on the drainage tube and includes a negative pressure ball and a switch defining a filling space. The filling space of the negative pressure ball communicates with the drainage channel of the drainage tube, and the negative pressure ball has a pressure relief joint connecting the drainage channel of the drainage tube and the filling space. The switch is disposed on the negative pressure ball and can close the pressure relief joint. The anti-backflow valve unit is disposed in the drainage channel of the drainage tube and located between the negative pressure unit and the input port of the bag body.

The utility model has the advantages that the negative pressure ball and the switch of the negative pressure unit can prevent the urine to be discharged from flowing back into the drainage tube, and reduce the clogging problem of the drainage tube to reduce the UTI risk of the patient.

Referring to Figures 1, 2 and 3, an embodiment of the novel negative pressure backflow urine bag is adapted to drain urine from a urethra of a patient and store it. The embodiment of the present invention comprises a bag body 2, a drainage tube 3, a negative pressure unit 4, a backflow prevention valve unit 5, an output tube 6, and a clamping unit 7.

The bag body 2 defines an accommodating space 20 and includes an input port 21 and an output port 22 that communicate with the accommodating space 20 .

The drainage tube 3 is connected to the input port 21 of the bag body 2 and defines a drainage channel 30. Specifically, the draft tube 3 of the present embodiment includes an upstream end 31 having a receiving end 311 and a discharge end 312 disposed oppositely, and a receiving end 321 having an opposite arrangement and a downstream end of a discharging end 322. Segment 32. In more detail, the receiving end 311 of the upstream section 31 of the draft tube 3 is for insertion in the urethra of the patient (not shown).

The negative pressure unit 4 is disposed between the upstream section 31 and the downstream section 32 and includes a negative pressure ball 41 and a switch 42 defining a filling space 410. The filling space 410 of the negative pressure ball 41 communicates with the drainage channel 30 of the drainage tube 3, and the negative pressure ball 41 has a first joint 411 and a second connecting the drainage channel 30 of the drainage tube 3 and the filling space 410. A joint 412, a pressure relief joint 413, and a one-way valve 414 surrounding the first joint 411 and located in the filling space 410. The first joint 411 of the negative pressure ball 41 is located in the discharge end 312 of the upstream section 31 of the draft tube 3, and the second joint 412 of the negative pressure ball 41 is located in the receiving end 321 of the downstream section 32 of the draft tube 3. The switch 42 of the negative pressure unit 4 is disposed on the negative pressure ball 41 and can close the pressure relief joint 413. In this embodiment of the present invention, the switch 42 of the negative pressure unit 4 is a resilient plug that is filled in the pressure relief joint 413. The negative pressure unit 4 of this embodiment of the present invention may be constructed of an integrally formed (e.g., injection molded) elastic material (e.g., silicone).

The anti-backflow valve unit 5 is disposed in the drainage channel 30 of the drainage tube 3 and located in the downstream section 32 of the drainage tube 3 between the negative pressure unit 4 and the input port 21 of the bag body 2.

The output tube 6 includes a receiving end 61 and a discharge end (not shown). The receiving end 61 of the output tube 6 is connected to the output port 22 of the bag body 2 to accommodate the space of the bag body 2. 20 communicates.

In actual use, the present invention inserts the receiving end 311 of the upstream section 31 of the drainage tube 3 into the urethra (not shown) of the patient. When a urine 81 to be discharged is accumulated in the drainage channel 30 of the upstream section 31, the medical staff can first open the switch 42 of the negative pressure unit 4 to release the switch 42 (ie, the elastic plug) from the pressure relief. The joint 413 is reduced in the filling space 410 in the negative pressure ball 41 to make the negative pressure ball 41 in a decompressed state (see FIG. 1), and the switch 42 (ie, the elastic plug) is filled in the pressure relief joint 413. . At this time, the urine 81 to be discharged accumulated in the upstream section 31 of the draft tube 3 can be drained from the first joint 411 of the negative pressure ball 41 by the negative pressure ball 41 in a reduced pressure state. A single check valve 414 enters the fill space 410 (shown in Figure 2). Once the urine 81 to be discharged is filled in the filling space 410 of the negative pressure ball 41, the one-way valve 414 located in the filling space 410 can prevent the urine 81 to be discharged from flowing back to the drainage tube 3. The upstream section 31 reduces the clogging problem of the upstream section 31 of the draft tube 3 to reduce the UTI risk of the patient.

It should be additionally noted that the medical staff can remove the switch 42 to disengage the elastic plug from the pressure relief joint 413 and accumulate from the pressure relief joint 413 in the filling space 410 through a syringe (not shown). The urine 81 to be discharged is withdrawn from the filling space 410 to cause the negative pressure ball 41 to reappear the decompressed state.

Further, when the patient needs to exclude a accumulated urine 82 in the bag body 2, the medical staff can remove the body 71 of the clamping unit 7 clamped on the output tube 6, so that the accumulation is made. The urine 82 is discharged from the discharge end (not shown) of the output tube 6 to thereby clear the accommodating space 20 of the bag body 2, and then reset the body 71 of the clamping unit 7 to the output tube 6. It is prevented that a continuous accumulated urine (not shown) is discharged from the discharge end (not shown) of the output pipe 6. Moreover, the body 71 of the clamping unit 7 can hold the output tube 6 to prevent the accumulated urine from being discharged from the discharge end (not shown) of the output tube 6, and the test piece capacity in the body 71. The groove 711 is further configured to insert a test paper 83, and the medical staff can drop the accumulated urine 82 from the through hole 712 of the body 71 to the test paper 83 to display whether the urine of the patient is in the urine through the test paper 83.
