Description

Technical Field

[0001] This utility model relates to the field of drainage equipment technology, specifically to a separate collection device for feces and urine. Background Technology

[0002] For patients with urinary incontinence, especially those with severe cases, the main challenge lies in the timely and appropriate management of excrement. Generally, disposable diapers are worn, and family members or medical staff check and change them regularly. This leads to fecal contamination of the patient's buttocks, and urine soaking the skin can cause irritation. Furthermore, the long-term, repetitive procedures are not only time-consuming and laborious for family members and medical staff, but also cause significant discomfort to the patient. If urinary incontinence occurs, catheters of various structures are used for catheterization. However, when an indwelling catheter is inserted, there is a risk of it entering the patient's body from the outside, causing infection, inflammation, and other discomfort. Utility Model Content

[0037] Therefore, in view of the aforementioned technical problems, this utility model proposes a separate collection device for feces and urine, such as... Figure 1-2 As shown. Figure 1 A schematic structural diagram of a separate fecal and urine collection device according to an embodiment of this application is shown; Figure 2 A schematic cross-sectional view of the separate collector of the feces and urine separate collection device according to an embodiment of this application is shown. The feces and urine separate collection device includes a feces receiver 1, a urine receiver 2, a feces drainage pipe 3, a urine drainage pipe 4, a feces collection bottle 5, a urine collection bottle 6, a first negative pressure conduit 7, a second negative pressure conduit 8, and a negative pressure device 9.

[0038] The fecal receiver 1 includes a fecal receiving port 11 and a fecal collection chamber 12. The fecal receiving port 11 is disposed on the surface of the fecal receiver 1, and the fecal collection chamber 12 is disposed inside the fecal receiver 1, with the fecal collection chamber 12 connected to the fecal receiving port 11. The fecal receiver 1 is used to receive patient feces, and the fecal receiving port 11 is located at the patient's defecation position to receive the patient's feces. Feces enter the fecal receiver 1 through the fecal receiving port 11 and are stored in the fecal collection chamber 12.

[0039] The urine receiver 2 includes a urine receiving port 21, a urine guiding cavity 22, a urine absorbent cotton 23, and a urine collection cavity 24. The urine receiving port 21 is provided on the surface of the urine receiver 2, and the urine guiding cavity 22 is provided inside the urine receiver 2. The urine guiding cavity 22 is connected to the urine receiving port 21. The urine absorbent cotton 23 is provided inside the urine guiding cavity 22, and one end of the urine absorbent cotton 23 is connected to the urine collection cavity 24.

[0040] The urine receiver 2 is used to receive the patient's urine. The urine receiving port 21 is located at the patient's urination position and is used to receive the patient's urine. Urine enters the urine guiding cavity 22 from the urine receiving port 21 and is absorbed by the urine-absorbing cotton 23. The urine-absorbing cotton 23 is close to the patient's urination position through the urine receiving port 21, increasing the contact area while absorbing urine. After the negative pressure device 9 starts, the unit pressure value brought by the negative pressure is reduced to reduce the discomfort of the human body and improve the absorption effect. It can be made of sponge or various cotton materials (medical nylon cotton is preferred). The urine-absorbing cotton 23 can be a hydrophilic filler, which has both the function of quickly absorbing urine and the hydrophobic effect. After the negative pressure starts, the urine is carried away from the urine-absorbing cotton 23. The sponge has a spatial structure, forming multiple cavities with pores to allow liquid to flow in and out. The urine-absorbing cotton 23 is connected to the urine collection chamber 24 at one end near the feces receiver 1.

The fecal collection bottle 5 is connected to the negative pressure device 9 through the first negative pressure conduit 7. The negative pressure device 9 provides negative pressure to the fecal drainage pipe 3 and the first negative pressure conduit 7. Under the action of negative pressure, the feces in the fecal collection chamber 12 enter the fecal collection bottle 5 through the fecal drainage pipe 3. The negative pressure device 9 provides negative pressure to the fecal drainage pipe 3 through the first negative pressure conduit 7, and the end of the fecal collection bottle 5 closest to the fecal drainage pipe 3 is connected to the first negative pressure conduit 7.

[0042] The first end of the urine drainage tube 4 is connected to the urine collection chamber 24, and the second end of the urine drainage tube 4 is connected to the urine collection bottle 6. The urine collection bottle 6 is connected to the negative pressure device 9 via the second negative pressure conduit 8. The negative pressure device 9 provides negative pressure to the urine drainage tube 4 and the second negative pressure conduit 8. Under the action of negative pressure, the urine in the urine collection chamber 24 flows through the urine drainage tube 4 into the urine collection bottle 6. The negative pressure device 9 provides negative pressure to the urine drainage tube 4 via the second negative pressure conduit 8, and the end of the urine collection bottle 6 closest to the urine drainage tube 4 is connected to the second negative pressure conduit 8. The first negative pressure conduit 7 can be connected to the second negative pressure conduit 8 and then to the negative pressure device 9.

[0043] According to the embodiment of this utility model, the separate collection device for feces and urine receives feces and urine respectively through feces receiver 1 and urine receiver 2. The negative pressure device 9 provides negative pressure to the feces drainage pipe 3 and urine drainage pipe 4 respectively through the first negative pressure conduit 7 and the second negative pressure conduit 8. Under the action of the negative pressure device 9, the feces and urine from the feces receiver 1 and urine receiver 2 are drained into the feces collection bottle 5 and urine collection bottle 6 respectively through the feces drainage pipe 3 and urine drainage pipe 4, so as to discharge urine and feces in a timely manner and improve patient comfort.

[0044] In one embodiment, the negative pressure device 9 includes a negative pressure switch 91, a negative pressure intensity regulator 92, and a negative pressure data display 93. The negative pressure switch 91 is used to turn the negative pressure device 9 on and off; the negative pressure intensity regulator 92 is used to adjust the negative pressure of the fecal drainage tube 3, the urine drainage tube 4, the first negative pressure conduit 7, and the second negative pressure conduit 8; and the negative pressure data display 93 is used to display the negative pressure of the fecal drainage tube 3, the urine drainage tube 4, the first negative pressure conduit 7, and the second negative pressure conduit 8.

[0045] In one embodiment, a weight sensor 51 is installed at the end of the feces collection bottle 5 furthest from the feces drainage pipe 3. The weight sensor 51 is used to convert the weight of the feces in the feces collection bottle 5 into an electrical signal. The weight sensor 51 is a device that converts the force or load applied by an object into an electrical signal. Its working principle is mainly based on technologies such as strain gauges, electromagnetic induction, and elastic elements. When the weight of an object is applied to the sensor, the elastic body inside the sensor deforms, causing the strain gauge bridge to lose balance, thereby outputting an electrical signal proportional to the weight.

[0046] In one embodiment, a weight signal processor 52 is installed at the end of the feces collection bottle 5 furthest from the feces drainage pipe 3. The weight signal processor 52 is used to receive, process, and output the electrical signals from the weight sensor 51. The weight signal processor 52 is a device for processing and converting weight signals, typically used in industrial weighing systems. Its main function is to convert the electrical signals generated by the weight sensor 51 into stable weight data and transmit it to a PLC or other control system via various communication protocols. When the feces in the feces collection bottle 5 exceed a specified weight, medical personnel replace the feces collection bottle 5.

[0047] In one embodiment, a liquid sensor 61 is installed at one end of the urine collection bottle 6 near the urine drainage tube 4. The liquid sensor 61 is used to detect the liquid level of the urine in the urine collection bottle 6. The working principle of the liquid sensor 61 is mainly based on the mutual conversion between physical quantities and electrical signals. It measures and controls parameters such as liquid level, flow rate, and pressure by detecting the physical or chemical properties of the liquid.

[0048] In one embodiment, a liquid weighing device 62 is installed at the end of the urine collection bottle 6 furthest from the urine drainage tube 4. The liquid weighing device 62, in conjunction with a liquid sensor 61, detects the weight of the urine in the urine collection bottle 6. The process of the liquid weighing device 62 detecting the weight via the liquid sensor 61 primarily relies on the weighing sensor converting the applied gravity of the liquid into an electrical signal, and then determining the weight of the liquid through calculation and correction. If the weight of the urine in the urine collection bottle 6 exceeds a specified weight or the urine level exceeds a specified level, medical personnel replace the urine collection bottle 6.

[0049] In one embodiment, a hydrogel patch 25 is provided on one end of the urine receiver 2 near the urine receiving port 21 for adhering to the patient's skin. This improves patient comfort and facilitates wound healing.

[0050] In one embodiment, the diameter of the urine drainage tube 4 is smaller than the diameter of the fecal drainage tube 3. This ensures that feces can be drained into the fecal collection bottle 5 and prevents blockage.

[0051] In one embodiment, the end of the urine receiver 2 near the urine collection chamber 24 is connected to the feces receiver 1. The urine receiver 2 and the feces receiver 1 are placed in appropriate positions, with the urine receiving port 21 aligned with the patient's urination position to receive the patient's urine, and the feces receiving port 11 aligned with the patient's defecation position to receive the patient's feces, so that both the patient's urine and feces can be collected simultaneously.

[0052] In one embodiment, the urine receiving port 21 is spindle-shaped, and the feces receiving port 11 is circular.

[0053] According to an embodiment of this utility model, the separate collection device for feces and urine receives feces and urine respectively through a feces receiver and a urine receiver. The negative pressure device provides negative pressure to the feces drainage pipeline and the urine drainage pipeline respectively through a first negative pressure conduit and a second negative pressure conduit. Under the action of the negative pressure device, the feces and urine from the feces receiver and the urine receiver are respectively drained into the feces collection bottle and the urine collection bottle through the feces drainage pipeline and the urine drainage pipeline, so as to discharge urine and feces in a timely manner and improve patient comfort.
