Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a bedpan. Background Technology

[0002] In the field of clinical medicine, urine output, as a basic and crucial physiological indicator, acts like a precise mirror, clearly reflecting the internal state of renal tissue perfusion and fluid balance, playing a vital role in patient condition assessment and treatment decisions.

[0003] As vital excretory organs, the kidneys play a crucial role in filtering blood, producing urine, and excreting metabolic waste and excess water. The process of urine production and excretion directly reflects the normal functioning of the kidneys' filtration, reabsorption, and endocrine regulation. When kidney tissue perfusion is adequate, the kidneys receive sufficient blood supply, their filtration function operates normally, and urine output remains at a relatively stable level. Conversely, if kidney tissue perfusion is insufficient, such as in cases of shock or severe dehydration, reduced blood perfusion impairs filtration, leading to decreased urine output or even anuria. Fluid balance is also a key factor in maintaining normal physiological functions, and changes in urine output can keenly reflect the body's water and electrolyte balance. For example, when there is excess water in the body, the kidneys increase urine output to excrete the excess water, maintaining stable osmotic pressure and volume; conversely, when there is insufficient water in the body, the kidneys reduce urine output to retain water and prevent dehydration.

[0004] In their daily work, medical staff must meticulously observe and analyze urine. Urine output is a key metric for assessing a patient's condition. Normally, an adult's 24-hour urine output is approximately 1000-2000 ml. If the 24-hour urine output is less than 400 ml, it is called oliguria; less than 100 ml is called anuria. Oliguria or anuria may indicate prerenal factors, such as insufficient blood volume or reduced cardiac output due to heart failure, leading to inadequate renal perfusion; it may also be due to renal factors, such as acute glomerulonephritis or acute tubular necrosis; or postrenal factors, such as bilateral ureteral stones or tumor compression causing urinary tract obstruction. A 24-hour urine output exceeding 2500 ml is called polyuria. Polyuria can be seen in diseases such as diabetes and diabetes insipidus, and may also be caused by the use of diuretics.

[0005] The color of urine also contains a wealth of health information. Normal urine is pale yellow to dark yellow, and its color intensity is mainly affected by factors such as urobilinogen, urobilin, food, and medications. When urine becomes lighter in color, or even colorless and transparent, it may indicate that the patient is drinking too much water, or that diseases such as diabetes insipidus are causing excessive dilution of the urine. If the urine color deepens, becoming dark yellow or amber, it may be due to insufficient water intake, excessive sweating leading to urine concentration, or it may be due to abnormal bilirubin metabolism caused by liver disease, resulting in elevated levels of urobilinogen and urobilin. If the urine is red, it may be hematuria, commonly seen in urinary tract infections, stones, tumors, or it may be caused by taking certain medications or eating foods containing pigments. If the urine is soy sauce-colored, it may be hemoglobinuria, often seen in hemolytic diseases. If the urine is milky white, it may be chyluria, usually associated with diseases such as filariasis and abdominal tumors.

[0006] Urine specific gravity is also an important indicator of kidney function and fluid balance. Normal urine specific gravity ranges from 1.010 to 1.025, and its fluctuation is affected by various factors such as urine volume, diet, and medication. Under normal kidney function, urine specific gravity increases when the body is dehydrated and decreases when the body is dehydrated. If urine specific gravity remains consistently around 1.010, it suggests severe impairment of the kidneys' concentrating and diluting functions, potentially indicating chronic kidney failure or other diseases.

[0007] By comprehensively observing and analyzing urine output, color, and specific gravity, medical staff can gain a more complete understanding of a patient's renal function, cardiac function, and blood volume. For example, when a patient's urine output decreases, urine color darkens, and specific gravity increases, combined with possible symptoms of dehydration such as thirst and dry skin, it can be preliminarily determined that the patient has insufficient blood volume. This can then lead to consideration of whether there is reduced cardiac output due to heart failure, or excessive fluid loss due to gastrointestinal bleeding or excessive sweating. Based on these assessments, medical staff can more accurately plan treatment, such as administering fluid resuscitation to correct insufficient blood volume, using cardiotonics to improve cardiac function, and adjusting the fluid resuscitation volume promptly according to changes in urine output to avoid serious complications such as heart failure due to excessive fluid resuscitation or shock due to insufficient fluid resuscitation.

[0008] However, in clinical practice, urine volume measurement, a seemingly basic procedure, faces numerous inconveniences and challenges. Currently, patients typically urinate into a bedpan during daily urination. Conventional bedpans are simply designed to collect waste and do not have urine volume measurement capabilities. When healthcare professionals need to obtain urine volume data, they must resort to a cumbersome method: carefully pouring the urine from the bedpan into a specialized measuring device. This process not only increases the workload and reduces efficiency for healthcare professionals but also easily leads to spillage and inaccurate measurements. For example, when pouring urine from the bedpan into the measuring device, the shape and opening size of the bedpan may cause urine to splash out, resulting in a lower measured volume than the patient's actual urine output; or the scale of the measuring device may be obscured by urine, affecting the accuracy of the urine volume reading. Furthermore, frequent urine transfer increases the risk of cross-infection, which is detrimental to patient health and medical safety.

[0009] This section provides background information related to this application, which is not necessarily prior art. Utility Model Content

[0011] To achieve the above objectives, the following technical solution is provided:

[0012] A bedpan, including a collection unit, the collection unit comprising:

[0013] The basin has a collection groove for collecting discharged liquid. A first outward flange is provided circumferentially at the opening of the collection groove. The upper surface of the first outward flange is flat and can withstand pressure from external objects.

[0014] The tube body is made of transparent material and is disposed on the side wall of the basin. The first end of the tube body is connected to the collection groove. The height of point A at the first end of the tube body is lower than the height of the bottom of the collection groove. The second end of the tube body extends upward at an angle. The height of point B at the second end of the tube body is greater than the height of the opening of the collection groove. The tube body is configured to not only measure the volume of the discharged liquid, but also be handheld.

[0015] A cover body is connected to the second end of the tube body, and the cover body is used to seal the second end of the tube body.

[0016] As an alternative to the bedpan, the outer wall of the tube is marked with graduations along its length; or the tube is equipped with a liquid level sensor.

[0017] As an optional solution for the bedpan, the outer wall surface of the cover is provided with an anti-slip structure, which includes anti-slip patterns, anti-slip protrusions, or anti-slip grooves.

[0018] As an optional feature of the bedpan, the bedpan also includes:

[0019] A water flow sound device is disposed on the lower surface of the first outward flange.

[0020] As an alternative to the toilet bowl, a second outward-facing edge is provided at the edge of the first outward-facing edge, which can block the water flow sound device.

[0021] As an optional solution for the chamber pot, the space enclosed between the pot body, the lower surface of the first outward-facing edge, and the second outward-facing edge is provided with a number of reinforcing ribs.

[0022] As an optional feature of the bedpan, the bedpan also includes:

[0023] The padding is made of sponge, silicone or rubber, and its shape is adapted to the shape of the first outward flange. The lower surface of the padding is detachably connected to the upper surface of the first outward flange.

[0024] As an optional solution for the toilet bowl, the lower surface of the liner is provided with a plurality of first limiting protrusions spaced apart circumferentially, and the upper surface of the first outward flange is provided with a plurality of first limiting grooves spaced apart circumferentially, wherein the first limiting protrusions are inserted into the first limiting grooves.

[0025] As an optional solution for the toilet bowl, the lower surface of the liner is provided with a plurality of second limiting grooves spaced apart circumferentially, and the upper surface of the first outwardly turned edge is provided with a plurality of second limiting protrusions spaced apart circumferentially, with the second limiting protrusions being inserted into the second limiting grooves.

[0026] As an alternative to the toilet bowl, the lower surface of the liner is bonded to the upper surface of the first outwardly turned edge.

[0027] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0028] The bedpan provided by this utility model allows the patient to squat on the first outward-curving edge of the basin. Urine is collected through a collection groove in the basin. A tube connects to the collection groove and extends upwards at an angle. The height of point A at the first end of the tube is less than the height of the bottom of the collection groove. When urine volume measurement is required, this facilitates the collection of all urine from the collection groove into the tube, improving measurement accuracy. It eliminates the need to pour the urine from the bedpan into a special measuring device, reducing the workload of medical staff and improving work efficiency. When the bedpan is laid flat, the second end of the tube extends upwards at an angle. The height of point B at the second end of the tube is greater than the height of the opening of the collection groove. This prevents urine from overflowing from the second end of the tube and makes it easier for the patient to hold the bedpan, facilitating adjustment of its position and urination.

[0050] By comprehensively observing and analyzing urine output, color, and specific gravity, medical staff can gain a more complete understanding of a patient's renal function, cardiac function, and blood volume. For example, when a patient's urine output decreases, urine color darkens, and specific gravity increases, combined with possible symptoms of dehydration such as thirst and dry skin, it can be preliminarily determined that the patient has insufficient blood volume. This can then lead to consideration of whether there is reduced cardiac output due to heart failure, or excessive fluid loss due to gastrointestinal bleeding or excessive sweating. Based on these assessments, medical staff can more accurately plan treatment, such as administering fluid resuscitation to correct insufficient blood volume, using cardiotonics to improve cardiac function, and adjusting the fluid resuscitation volume promptly according to changes in urine output to avoid serious complications such as heart failure due to excessive fluid resuscitation or shock due to insufficient fluid resuscitation.

[0051] However, in clinical practice, urine volume measurement, a seemingly basic procedure, faces numerous inconveniences and challenges. Currently, patients typically urinate into a bedpan during daily urination. Conventional bedpans are simply designed to collect waste and do not have urine volume measurement capabilities. When healthcare professionals need to obtain urine volume data, they must resort to a cumbersome method: carefully pouring the urine from the bedpan into a specialized measuring device. This process not only increases the workload and reduces efficiency for healthcare professionals but also easily leads to spillage and inaccurate measurements. For example, when pouring urine from the bedpan into the measuring device, the shape and opening size of the bedpan may cause urine to splash out, resulting in a lower measured volume than the patient's actual urine output; or the scale of the measuring device may be obscured by urine, affecting the accuracy of the urine volume reading. Furthermore, frequent urine transfer increases the risk of cross-infection, which is detrimental to patient health and medical safety.

[0052] To eliminate the need to pour urine from the bedpan into a dedicated measuring device for urine volume measurement, thereby reducing the workload of medical staff, improving work efficiency, ensuring measurement accuracy, and ensuring the bedpan is easy to handle, this embodiment provides a bedpan, which is described below in conjunction with... Figures 1 to 10 The specific content of this embodiment will be described in detail. It should be noted that the vertical direction and height direction mentioned in this embodiment refer to... Figure 1 The Z direction in the equation. Figure 5The height difference H1 and height difference H2 can be designed according to actual usage requirements, and no further restrictions are imposed here.

[0053] like Figures 1 to 5 As shown, in this embodiment, the toilet bowl includes a collection unit, which includes a basin body 1, a tube body 2, and a cover body 3. The basin body 1 has a collection groove 11 for collecting discharged liquid. A first outward flange 12 is circumferentially provided at the opening of the collection groove 11. The upper surface of the first outward flange 12 is flat and can withstand pressure from external objects. The tube body 2 is made of transparent material and is disposed on the side wall of the basin body 1. The first end of the tube body 2 is connected to the collection groove 11. The height of point A at the first end of the tube body 2 is lower than the height of the bottom of the collection groove 11. The second end of the tube body 2 extends upward at an angle. The height of point B at the second end of the tube body 2 is greater than the height of the opening of the collection groove 11. The tube body 2 is configured to not only measure the volume of discharged liquid but also be handheld. In this embodiment, the basin body 1 and the tube body 2 are integrally formed. The cover body 3 is connected to the second end of the tube body 2 and is used to seal the second end of the tube body 2. For example, the cover 3 is threaded to the second end of the tube 2.

[0054] Understandably, the basin 1, as the core component of the bedpan for collecting urine, is designed with practical usage needs and ergonomic principles in mind. The collection groove 11 on the basin 1 acts as a precise container specifically for collecting the patient's urine. The shape and size of this collection groove 11 are carefully designed to ensure that urine flows smoothly without splashing during excretion, laying a solid foundation for accurate measurement. In this embodiment, the cross-sectional shape of the collection groove 11 is a combination of a triangle and a semi-circle. A first outward-facing flange 12 is circumferentially arranged at the opening of the collection groove 11, with a flat upper surface. When the patient squats on the first outward-facing flange 12 of the basin 1, this flange can evenly and stably bear the pressure from external objects, ensuring the patient is in a safe and comfortable urination posture. Simultaneously, the flat upper surface makes the patient more stable during squatting, reducing the risk of urine spillage due to bedpan shaking or tilting, further ensuring the integrity and accuracy of urine collection.

[0055] The tube 2 serves as a channel connecting the collection groove 11 of the basin 1 to the outside. Made of transparent material, the tube 2 acts as a "window" for medical staff to observe urine. During urine collection and measurement, medical staff can clearly observe the color, transparency, and presence of impurities through the transparent tube 2, providing a direct basis for preliminary assessment of the patient's condition. For example, abnormally dark urine may indicate dehydration or kidney disease; cloudy urine or sediment may suggest urinary tract infections. The tube 2 is located on the side wall of the basin 1, with its first end tightly connected to the collection groove 11, and the height of point A at the first end is lower than the bottom of the collection groove 11. This design fully utilizes the physical principles of liquid flow. When urine volume needs to be measured, by gradually tilting the bedpan, the urine in the collection groove 11 flows smoothly into the tube 2 under its own gravity, ensuring that all urine is collected in the tube 2, greatly improving the accuracy of the measurement. Compared to the traditional method of pouring urine from the bedpan into a special measuring device, this method avoids potential problems such as urine spillage and measurement errors during transfer, reducing the workload of medical staff and improving work efficiency. The second end of the tube 2 extends upwards at an angle, and the height of point B at the second end is greater than the height of the opening of the collection groove 11. This design has a dual advantage. Firstly, when the bedpan is laid flat, the upwardly extending second end of the tube 2 forms a natural "barrier," effectively preventing urine from overflowing from the second end of the tube 2, avoiding urine contamination of the surrounding environment, and ensuring the cleanliness and hygiene of the ward. Secondly, this upwardly angled design greatly facilitates the patient's handling of the bedpan. Patients can easily hold the bedpan according to their needs, adjusting its position and angle to ensure that the bedpan remains in a stable and suitable position during urination, further improving the comfort and accuracy of urination.

[0056] The cap 3 is tightly connected to the second end of the tube 2, and its main function is to seal the second end of the tube 2. In this embodiment, the cap 3 is exemplarily connected to the second end of the tube 2 by a threaded connection. This connection method has many advantages. It not only provides a secure connection and effectively prevents urine leakage from the second end of the tube 2 when not being measured, but also facilitates operation by medical personnel. When urine volume needs to be measured, medical personnel can easily rotate the cap 3 to open it and measure the urine in the tube 2; after the measurement is completed, the cap 3 is rotated again to seal it. The operation is simple and quick, greatly saving time and effort.

[0057] In addition, the basin 1 and the tube 2 in this embodiment adopt an integrated molding structure. This structure not only enhances the overall strength and stability of the toilet and reduces problems such as urine leakage caused by loose parts or loose connections, but also simplifies the manufacturing process, reduces production costs, and improves the reliability and durability of the product.

[0058] Furthermore, in some application scenarios, the outer wall of the tube 2 is marked with graduations 21 along its length. Based on the correspondence between liquid volume and liquid level, when urine enters the tube 2, the liquid level will rise as the amount of urine increases. Medical staff only need to observe the graduation value corresponding to the liquid level to quickly and accurately obtain urine volume information. The graduations 21 are clearly visible, and medical staff can complete urine volume measurement by visual observation alone without the need for additional tools or equipment, greatly saving time and effort.

[0059] Furthermore, in some application scenarios, the tube 2 is equipped with a liquid level sensor. The liquid level sensor is typically installed at a specific location on the tube 2, capable of sensing the real-time liquid level within the tube 2 and converting the liquid level information into an electrical signal for transmission. These electrical signals, after processing, can be displayed digitally or graphically on a matching display screen, allowing medical personnel to obtain urine volume information simply by viewing the screen. The liquid level sensor features high precision and high sensitivity, enabling real-time and accurate monitoring of changes in urine level. The liquid level sensor solution is unaffected by factors such as light and angle, resulting in more accurate and reliable measurement results. In addition, the liquid level sensor can automatically record and transmit data. Medical personnel can connect to a medical information system to upload urine volume data to the patient's electronic medical record in real time, facilitating data management and analysis. This embodiment provides two measurement solutions for the bedpan tube 2: the scale marking 21 and the liquid level sensor, offering diverse options for clinical urine volume measurement from the perspectives of traditional intuitiveness and intelligent precision, respectively.

[0060] Furthermore, the outer wall surface of the cover 3 is provided with an anti-slip structure 31, which includes anti-slip patterns, anti-slip protrusions, or anti-slip grooves. In medical care, the use of bedpans involves the safety of patients and medical staff. As an important component of the bedpan, the anti-slip performance of the cover 3 is directly related to the safety during operation. If the cover 3 lacks an effective anti-slip structure 31, it is easy to slip off during opening and closing due to hand slippage, causing urine to spill out. This not only pollutes the surrounding environment and increases cleaning workload, but may also expose patients and medical staff to urine, leading to infection risks. In addition, the slippage of the cover 3 may also damage the bedpan itself, affecting its normal use. In this embodiment, the anti-slip structure 31 provided on the outer wall surface of the cover 3, whether it is an anti-slip pattern, anti-slip protrusion, or anti-slip groove, can significantly increase the friction between the hand and the cover 3, effectively preventing the cover 3 from slipping off. When medical staff measure urine output for patients, they can hold the lid 3 more steadily and operate accurately. Patients using bedpans can also open and close the lid 3 with greater peace of mind, avoiding embarrassment and safety hazards caused by accidental slippage. When medical staff need to frequently open and close the lid 3 for tasks such as urine output recording and bedpan cleaning, the anti-slip structure 31 allows them to complete the operation more easily and quickly. For example, when recording urine output, medical staff do not need to spend extra time and effort adjusting their hand posture to prevent the lid 3 from slipping; they can simply hold the lid 3 with the anti-slip structure 31 naturally to quickly open or close the lid 3.

[0061] Furthermore, the bedpan also includes a water flow sound device 4, which is located on the lower surface of the first outward-flared edge 12. Postoperative urinary retention is a common problem faced by patients due to the effects of anesthesia during surgery, often requiring re-insertion of a urinary catheter. The addition of the water flow sound device 4 can address this issue, integrating the sound of running water into the new bedpan technology. With the aging population, this new bedpan can provide convenience for disabled elderly individuals and reduce the incidence of sacrococcygeal pressure sores. From a concealment perspective, the lower surface of the first outward-flared edge 12, as an extension of the bedpan's edge, is relatively concealed and will not affect the overall appearance or ease of use of the bedpan. Patients using the bedpan do not need to worry about visual or operational interference from the device, maintaining a natural and comfortable experience. From a functional perspective, this location facilitates the propagation and diffusion of sound. The lower surface of the first outward-facing edge 12 is relatively close to the internal space of the bedpan. When the water flow sound device 4 emits a simulated water flow sound, the sound can be transmitted more directly and clearly into the bedpan, thus better affecting the patient's auditory experience and enhancing the simulation effect. At the same time, this positioning also helps protect the device from external impacts and damage, extending its service life and reducing maintenance costs.

[0062] Furthermore, a second outward-facing edge 13 is provided at the edge of the first outward-facing edge 12. The second outward-facing edge 13 extends downward vertically and can block the water flow sound device 4. The first outward-facing edge 12, as the basic structure of the toilet bowl edge, provides stable support and a certain degree of protection for the entire toilet bowl. The second outward-facing edge 13, located at the edge of the first outward-facing edge 12, is a further optimized design based on this. The second outward-facing edge 13 extends downward vertically, forming an L-shaped structure with the first outward-facing edge 12. This unique positional relationship allows the second outward-facing edge 13 to naturally cover the water flow sound device 4, constructing a sturdy protective barrier. From a spatial layout perspective, the extension length of the second outward-facing edge 13 has been carefully calculated to completely block the water flow sound device 4 without interfering with other functional areas of the toilet bowl. It fits tightly against the edge of the first outward-facing edge 12, forming an organic whole with the main body of the toilet bowl, ensuring the overall structural compactness of the toilet bowl while effectively protecting the water flow sound device 4.

[0063] Furthermore, a plurality of reinforcing ribs 14 are provided in the space enclosed between the basin body 1, the lower surface of the first outward flange 12, and the second outward flange 13. The reinforcing ribs 14 can be triangular, trapezoidal, rectangular, etc., and different shapes of reinforcing ribs 14 have different mechanical properties. In this embodiment, a combination of various shapes of reinforcing ribs 14 may be used to fully utilize the advantages of each shape. In a medical care environment, the bedpan may be subjected to various complex external forces. For example, when moving the bedpan in a ward, it may accidentally collide with walls or other medical equipment; during patient use, due to body movement or improper force, significant pressure may be applied to the bedpan. The setting of reinforcing ribs 14 can significantly enhance the structural strength of the bedpan, enabling it to better resist these external impacts. The reinforcing ribs 14 improve the overall rigidity of the bedpan by increasing the cross-sectional area of ​​the structure and changing the stress distribution. When subjected to external forces, the reinforcing ribs 14 can limit the deformation of the basin body 1, the first outward flange 12, and the second outward flange 13, preventing structural damage such as cracks and fractures. Even if the toilet bowl is subjected to a large external impact, the reinforcing rib 14 can absorb and disperse some of the energy, protecting critical internal components (such as the water flow sound device 4) from damage and ensuring the normal use of the toilet bowl. For example, when the edge of the toilet bowl is subjected to a lateral impact, the second outward flange 13 first bears the impact force, and the reinforcing rib 14 will immediately play its role, transmitting the impact force along the rib direction of the reinforcing rib 14 to the bowl body 1 and the first outward flange 12, so that the entire structure shares the external force, thereby effectively protecting the integrity of the toilet bowl.

[0064] Furthermore, the bedpan also includes a liner 5, made of sponge, silicone, or rubber. The shape of the liner 5 is adapted to the shape of the first outward-facing edge 12, and the lower surface of the liner 5 is detachably connected to the upper surface of the first outward-facing edge 12. Sponge is known for its soft texture and good elasticity. When the patient sits on the bedpan, the sponge liner 5 can deform according to the shape and pressure distribution of the patient's buttocks, providing even and comfortable support, effectively reducing the pressure on the area where the patient's buttocks contact the edge of the bedpan, and avoiding discomfort or pressure sores caused by prolonged use. At the same time, sponge has a certain degree of water absorption, which can absorb a small amount of liquid splashed from the patient's excrement to a certain extent, keeping the area around the patient's buttocks relatively dry and improving the comfort of use. However, sponge material also needs to be cleaned and replaced regularly to prevent bacterial growth. Silicone has excellent flexibility and a smooth surface. Its soft texture can conform well to the patient's body curves, giving the patient a skin-friendly touch and reducing discomfort caused by friction. The smooth surface makes it difficult for excrement to adhere, facilitating cleaning and disinfection, and effectively reducing the risk of cross-infection. Furthermore, silicone material possesses excellent chemical stability, resisting corrosion from various cleaning agents and disinfectants, resulting in a long service life suitable for long-term use in medical environments. Rubber material exhibits high strength and wear resistance, capable of withstanding significant pressure and friction without easily being damaged. It also possesses good resilience, quickly returning to its original shape during use, providing stable support for patients. The rubber pad 5 also offers some anti-slip properties, preventing patients from slipping due to body movement during use, thus increasing safety. Simultaneously, rubber material is relatively easy to clean, meeting the high hygiene requirements of medical environments. The lower surface of the pad 5 is detachably connected to the upper surface of the first outward-facing edge 12. This design fully considers the practical needs of medical care work, offering significant advantages in terms of hygiene maintenance and usage flexibility.

[0065] The detachable connection allows the bedpan liner 5 to be easily removed from the bedpan for cleaning and disinfection. During daily use, bedpans easily accumulate various bacteria and dirt, especially the bedpan liner 5, which comes into direct contact with the patient's body, requiring regular and thorough cleaning and disinfection. The detachable connection allows healthcare professionals to easily separate the bedpan liner 5 from the bedpan and thoroughly clean it using specialized cleaning agents and disinfection equipment, ensuring that the liner liner 5 meets medical standards. This not only helps prevent cross-infection and protects the patient's health and safety but also extends the lifespan of the bedpan liner 5. Furthermore, the detachable design facilitates the replacement of the bedpan liner 5. When the bedpan liner 5 becomes worn, deformed, or damaged, healthcare professionals can promptly replace it with a new one without replacing the entire bedpan, reducing operating costs. Additionally, for patients with different conditions and needs, different materials and properties of the bedpan liner 5 can be selected for replacement, increasing the flexibility and personalization of bedpan use.
