Abstract
Description
Technical Field
[0001] This utility model relates to the field of assistive care equipment, and in particular to disposable airbag bedpans. Background Technology
[0002] Currently, most bedpans used in clinical settings are pre-made plastic bedpans. When using them, medical staff need to lift the patient's buttocks a certain distance off the bed to place the bedpan under them. This process is not only laborious but can also cause additional pain and risks for weak or immobile patients. Furthermore, the hard edges and surface of the pre-made plastic bedpan can cause discomfort and significantly impact the patient's experience.
[0003] In existing technologies, medical staff have to lift the patient's buttocks high to place the bedpan, which is laborious and may cause pain and secondary injury to the patient. The material is hard and cannot conform to the curve of the buttocks, with the edges and surface directly pressing on the patient's buttocks, resulting in low comfort. There is a lack of lumbar support, causing lumbar fatigue during defecation. The surface has poor anti-slip properties, making the bedpan prone to sliding during use, increasing risks and nursing difficulty. The leak-proof effect is poor, easily leading to excrement leakage, soiling clothes and bedding, causing infections, and affecting patient recovery, resulting in poor practicality. Therefore, this utility model discloses a disposable air-filled bedpan to solve the problems of existing fixed plastic bedpans, such as inconvenient placement, low patient comfort, lack of lumbar support, poor anti-slip properties, and poor leak-proof effect. Utility Model Content
[0004] In view of this, the purpose of this utility model is to propose a disposable airbag bedpan to solve the problems of existing fixed plastic bedpans, such as inconvenience in placement, low patient comfort, lack of lumbar support, poor anti-slip performance, and poor leak prevention.
[0005] To achieve the above objectives, this utility model provides a disposable airbag commode, comprising: a rubber base, with armrest blocks installed on both sides of one end of the rubber base, and finger grip grooves provided on the armrest blocks; a rubber base installed on one side wall of the rubber base; a lumbar support base installed on the upper part of the rubber base; a one-way inflation valve port installed on one side wall of the rubber base; a U-shaped airbag installed on one side wall of the other end of the rubber base; an exhaust valve port installed on the other side wall of the U-shaped airbag; and a bottom pad installed at the bottom of the inner wall of the U-shaped airbag.
[0006] Preferably, the U-shaped airbag is composed of a hydrophilic PU membrane, a TPU composite membrane, and platinum silicone, wherein the hydrophilic PU membrane is the outer surface of the U-shaped airbag, the TPU composite membrane is installed at the other end of the hydrophilic PU membrane, and the platinum silicone is installed at the other end of the TPU composite membrane.
[0007] Preferably, the upper surface of the waist support base is evenly arrayed with multiple soft, non-slip protrusions.
[0008] Preferably, the upper surface of the lumbar support base slopes from one end of the armrest block to one end of the U-shaped airbag.
[0009] Preferably, the hydrophilic PU film on the outer surface of the U-shaped airbag has a plurality of soft, anti-slip protrusions evenly arranged in an array.
[0010] Preferably, the end of the U-shaped airbag away from the rubber base is inclined, and the upper end of the U-shaped airbag, which is inclined, is symmetrically provided with leg adaptation grooves.
[0011] Preferably, a leak-proof strip is installed on the lower side wall of the inner wall of the U-shaped airbag.
[0012] The beneficial effects of this utility model are:
[0013] This novel disposable airbag bedpan features a U-shaped airbag that is soft and flat when uninflated. Medical staff can easily place the bedpan in the correct position without excessively raising the patient's buttocks, significantly saving effort and reducing the risk of discomfort caused by buttock elevation. This makes bedpan placement safer and more efficient. Regarding patient comfort, the U-shaped airbag is constructed from a hydrophilic PU membrane, a TPU composite membrane, and platinum silicone. These materials are soft and skin-friendly, perfectly conforming to the curve of the patient's buttocks, effectively reducing pressure and avoiding the stiffness and discomfort of traditional hard plastic bedpans. A key highlight is the lumbar support base, which provides solid lumbar support, effectively supporting the lower back during defecation and greatly reducing lumbar fatigue. Furthermore, the evenly distributed soft, non-slip protrusions on the hydrophilic PU membrane of the lumbar support base and the outer surface of the U-shaped airbag not only increase friction between the bedpan and the patient's body, preventing slippage, but also further enhance stability and comfort, allowing patients to complete the defecation process more relaxedly. In terms of slip resistance, the design of soft, non-slip protrusions effectively enhances the friction between the bedpan and the patient's body, ensuring the bedpan remains stable during use and preventing the danger and inconvenience caused by the bedpan sliding. It also facilitates the nursing work of medical staff. Regarding leak prevention, the leak-proof strip installed on the lower side of the middle of the inner wall of the U-shaped airbag plays a crucial role. It tightly blocks the leakage of excrement, preventing excrement from contaminating the patient's clothing and bed, reducing nursing workload, lowering the risk of infection, and creating a more hygienic and safe environment for the patient, thus significantly promoting their recovery.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0022] This utility model provides, for example Figures 1 to 3The disposable airbag bedpan shown includes: a rubber base 1, with handrail blocks 2 installed on both sides of one end of the rubber base 1, and finger grip grooves 3 on the handrail blocks 2; a rubber base 1 installed on one side wall of the rubber base 1; a lumbar support base 4 installed on the upper part of the rubber base 1; a one-way inflation valve port 6 installed on one side wall of the rubber base 1; and a U-shaped airbag 8 installed on one side wall of the other end of the rubber base 1, with an exhaust valve port 7 installed on the other side wall of the U-shaped airbag 8; and a bottom pad 10 installed at the bottom of the inner wall of the U-shaped airbag 8. The U-shaped airbag 8 of this disposable airbag bedpan is soft and flat when not inflated, allowing medical staff to easily place the patient in a suitable position without excessively raising the patient's buttocks, significantly saving operational energy, reducing the risk of discomfort caused by raising the buttocks, and making the bedpan placement process safer and more efficient. In terms of enhancing patient comfort, the U-shaped airbag 8 is constructed from a hydrophilic PU film (hydrophilic polyurethane film) 12, a TPU composite film (thermoplastic polyurethane elastomer composite film) 13, and platinum silicone (platinum vulcanized silicone) 14. These materials are soft and skin-friendly, perfectly conforming to the curves of the patient's buttocks, effectively reducing pressure on the buttocks and avoiding the stiffness and discomfort associated with traditional hard plastic bedpans. Meanwhile, the lumbar support base 4 is a major highlight, providing solid lumbar support for the patient, effectively supporting the lower back during defecation and greatly reducing lumbar fatigue. Furthermore, the evenly distributed soft, non-slip protrusions 5 on the hydrophilic PU film 12 of the lumbar support base 4 and the outer surface of the U-shaped airbag 8 not only increase the friction between the bedpan and the patient's body, preventing slippage, but also further enhance the stability and comfort of the patient during use, allowing them to complete the defecation process more relaxedly. In terms of slip prevention, the design of soft anti-slip protrusions 5 effectively enhances the friction between the bedpan and the patient's body, ensuring the bedpan remains stable during use and avoiding the danger and inconvenience caused by the bedpan sliding. It also facilitates the nursing work of medical staff. Regarding leakage prevention, the leak-proof strip 9 installed on the lower side of the inner wall of the U-shaped airbag 8 plays a crucial role. It tightly blocks the leakage of excrement, preventing excrement from contaminating the patient's clothing and bed, reducing nursing workload, lowering the risk of infection, and creating a more hygienic and safe environment for the patient, thus effectively promoting the patient's recovery.
[0023] Furthermore, in this example, such as Figure 3As shown, the U-shaped airbag 8 is composed of a hydrophilic PU membrane 12, a TPU composite membrane 13, and platinum silicone 14. The hydrophilic PU membrane 12 forms the outer surface of the U-shaped airbag 8, and the TPU composite membrane 13 is installed at the other end of the hydrophilic PU membrane 12. The platinum silicone 14 is installed at the other end of the TPU composite membrane 13. When using this disposable airbag bedpan, air is first injected into the U-shaped airbag 8 through the one-way inflation valve 6 installed on one side wall of the rubber base 1. In specific operation, a medical inflation device can be connected to the one-way inflation valve 6 to slowly inject gas into the U-shaped airbag 8. The gas enters the U-shaped airbag 8, which is composed of the hydrophilic PU membrane (hydrophilic polyurethane film) 12, the TPU composite membrane (thermoplastic polyurethane elastomer composite membrane) 13, and the platinum silicone (platinum vulcanized silicone) 14, in sequence. As gas is continuously injected, the U-shaped airbag 8 gradually expands and unfolds. Because the hydrophilic PU membrane 12 has good hydrophilicity and softness, the TPU composite membrane 13 has excellent elasticity and abrasion resistance, and the platinum silicone 14 provides good sealing and comfort, the U-shaped airbag 8 can conform well to the curve of the patient's buttocks, forming a stable support structure. This conforming design not only improves the patient's comfort during use but also effectively prevents excrement leakage. After the U-shaped airbag 8 is inflated to the appropriate size and shape, inflation is stopped and the one-way inflation valve 6 is closed to ensure that no gas leakage occurs. At this time, the patient can use the bedpan normally for defecation and other operations. The soft material and conforming design of the U-shaped airbag 8 can reduce the pressure on the patient's buttocks, while the lumbar support base 4 provides support for the patient's waist, further improving the comfort of use. After use, open the exhaust valve 7 installed on the other side wall of the U-shaped airbag 8 and gently squeeze the U-shaped airbag 8 to expel the gas inside. As the gas is expelled, the U-shaped airbag 8 gradually contracts and becomes smaller, making it easy to remove from under the patient's buttocks. The bedpan can then be discarded for single use, avoiding the risk of cross-infection and ensuring hygiene and safety.
[0024] Furthermore, in this example, such as Figure 1 and Figure 2As shown, the upper surface of the lumbar support base 4 has a uniform array of soft, non-slip protrusions 5. The upper surface of the lumbar support base 4 slopes from one end of the armrest block 2 to one end of the U-shaped airbag 8. The hydrophilic PU film 12 on the outer surface of the U-shaped airbag 8 has a uniform array of soft, non-slip protrusions 5. The end of the U-shaped airbag 8 furthest from the rubber base 1 is inclined, and the upper surface of the inclined U-shaped airbag 8 has symmetrically provided leg adaptation grooves 11. A leak-proof strip 9 is installed on the lower side of the inner wall of the U-shaped airbag 8. These soft, non-slip protrusions 5 are typically made of soft rubber or silicone. When the patient lies on the bedpan, the soft, non-slip protrusions 5 increase the friction between the lumbar support base 4 and the patient's lower back skin. On the one hand, this friction prevents the lumbar support base 4 from slipping due to body movement during defecation, ensuring that the lumbar support base 4 always stably supports the patient's lower back. On the other hand, the soft material of the protrusions does not put excessive pressure on the patient's lower back, ensuring both anti-slip effect and patient comfort. The upper surface of the lumbar support base 4 is designed from one end of the armrest block 2 to one end of the U-shaped airbag 8, sloping downwards. This inclined design conforms to ergonomic principles and can better fit the natural curve of the patient's lower back. The lumbar support base 4 can provide just the right amount of support according to the shape of the patient's lower back, allowing the patient's lower back muscles to relax, reducing fatigue caused by maintaining a sitting posture for a long time, and improving the overall comfort of the patient when using the bedpan. Multiple soft anti-slip protrusions 5 are evenly arranged on the hydrophilic PU film 12 on the outer surface of the U-shaped airbag 8. The hydrophilic PU film 12 itself has good hydrophilicity and softness, and can closely fit the patient's buttocks skin. The soft, non-slip protrusions 5 further increase friction with the skin, effectively preventing the U-shaped airbag 8 from slipping during use. When the patient moves slightly, the soft, non-slip protrusions 5 provide sufficient resistance to ensure the U-shaped airbag 8 remains in the correct position, providing stable support and preventing discomfort caused by slippage. The end of the U-shaped airbag 8 furthest from the rubber base 1 is angled, a design that better adapts to the natural posture of the patient's legs. When the patient lies on the bedpan, the angled end of the U-shaped airbag 8 provides a more suitable support angle for the legs, allowing them to relax naturally and reducing muscle tension. Symmetrical leg adaptation grooves 11 are provided on the upper, angled surface of the U-shaped airbag 8. These grooves accommodate the patient's legs, preventing direct contact and pressure between the legs and the surface of the U-shaped airbag 8. They also guide the patient to position their legs appropriately, further improving comfort and stability when using the bedpan. A leak-proof strip 9 is installed on the lower side wall of the middle part of the inner wall of the U-shaped airbag 8. The leak-proof strip 9 is usually made of a soft material with good sealing properties, such as rubber or silicone.When a patient defecates, the excrement falls into the U-shaped airbag 8. The leak-proof strip 9 fits tightly against the excrement, preventing leakage from the bottom or side walls of the airbag. The presence of the leak-proof strip 9 forms an effective sealing barrier, ensuring that the excrement is safely collected within the U-shaped airbag 8. This prevents excrement from contaminating the patient's clothing and bedding, reduces nursing workload, lowers the risk of infection, and provides a more hygienic and safer environment for the patient.
