Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical consumables technology, and in particular relates to a leak-proof medical pad. Background Technology
[0002] The primary purpose of medical drapes is to prevent bodily fluid leakage during various surgeries, effectively isolate and prevent cross-infection, protect the operating table surface from contamination, and reduce the spread of pathogens such as bacteria and viruses. Medical drapes are commonly used medical supplies in hospitals. They are typically laid on top of the bed sheets to prevent patients from soiling them. During surgery, bodily fluids from the patient will flow onto the medical drape. However, existing medical drapes rely solely on cotton wicks, which have limited absorbency, and the fluid within the wicks is prone to leakage. When excessive bodily fluid leakage occurs, it will flow down the medical drape onto the operating table or bed. Medical staff will then need to change the drape during the surgery, increasing their workload, providing a poor experience for the patient, and potentially increasing surgical risks. Therefore, existing medical drapes, due to their poor absorbency, require frequent changes, resulting in a heavy workload for staff and potentially affecting the quality of the patient's surgery. Utility Model Content
[0003] To address the problem of poor water retention in existing medical drapes, requiring frequent replacements during surgery, this invention provides a leak-proof medical drape. The drape includes a drape body, which comprises a horizontally positioned pad made of breathable medical gauze. The top of the pad has a non-woven fabric layer. Non-woven fabric, also known as nonwoven cloth, is made from oriented or randomly arranged fibers through friction, bonding, adhesion, or a combination of these methods, and serves to isolate pathogens. The top of the non-woven fabric layer is equipped with a leak-proof mechanism, which includes a liquid storage layer and a flow guiding layer at the top of the liquid storage layer. The liquid storage layer has several liquid storage slots, and the flow guiding layer has several leakage through-holes corresponding to the liquid storage slots. These leakage through-holes are inverted frustum shapes, with a larger diameter at the top and a smaller diameter at the bottom, facilitating the flow of bodily fluids from top to bottom into the liquid storage slots. The surface tension of the bodily fluids reduces upward backflow. The lower end of each liquid storage slot is inverted frustum shape, while the upper end is upright frustum shape. Absorbent cotton is placed inside each liquid storage slot to effectively absorb the bodily fluids and reduce leakage.
[0004] Preferably, a cotton cloth layer is provided at the top of the flow guiding layer.
[0005] Preferably, the back of the gasket is provided with a plurality of double-sided adhesive tapes.
[0006] The above scheme has the following advantages:
[0007] The drainage holes within the drainage layer are shaped like inverted frustums, with a larger diameter at the top and a smaller diameter at the bottom. This facilitates the flow of bodily fluids from top to bottom into the reservoir holes, reducing backflow due to surface tension. The reservoir holes are also shaped like upright frustums, and contain absorbent cotton that effectively absorbs the fluids, minimizing leakage. Double-sided adhesive tape allows for easy attachment of the pads to the nursing bed, reducing the likelihood of the medical pads lifting. Attached Figure Description

[0012] like Figure 1-2 As shown, a leak-proof medical diaper includes a diaper body 1, which includes a horizontally positioned pad 2 made of breathable medical gauze. The top of the pad 2 has a non-woven fabric layer 3. Non-woven fabric, also known as nonwoven cloth, is made of oriented or randomly arranged fibers through friction, bonding, adhesion, or a combination of these methods, and serves to isolate pathogens. The top of the nonwoven fabric layer 3 is equipped with a leak-proof mechanism 4, which includes a liquid storage layer 5 and a flow guiding layer 6. The liquid storage layer 5 has several liquid storage slots 51, and the flow guiding layer 6 has several leakage through-holes 61 corresponding to the liquid storage slots 51. The leakage through-holes 61 are inverted frustum shapes, with a larger diameter at the top and a smaller diameter at the bottom, facilitating the flow of bodily fluids from top to bottom into the liquid storage slots 51. The surface tension of the bodily fluids reduces upward backflow. The lower end of the liquid storage slot 51 is inverted frustum shape, and the upper end is upright frustum shape. Absorbent cotton 52 is installed inside the liquid storage slot 51 to effectively absorb the bodily fluids within, reducing the outflow of bodily fluids from the liquid storage slot 51.
[0013] Preferably, the top of the flow guiding layer 6 is provided with a cotton cloth layer 7.
[0014] Preferably, the back of the gasket 2 is provided with a plurality of double-sided adhesive tapes 21.
[0015] Usage process:
[0016] In use, this utility model involves taking a medical nursing pad, opening the pad body 1, placing the side with double-sided adhesive tape 21 facing down, peeling off the protective paper of the double-sided adhesive tape 21, and then sticking it to the operating table or nursing bed with the cotton cloth layer 7 facing up. The patient lies on the cotton cloth layer 7. When medical staff perform surgery on the patient, the patient's bodily fluids flow down, then move through the cotton cloth layer 7 to the drainage layer 6, and fall through the leakage holes 61 on the drainage layer 6 into the storage tank holes 51 on the storage layer 5. The fluids are then absorbed by the absorbent cotton 52 in the storage tank holes 51. After the surgery is completed, the medical nursing pad can be removed.
[0017] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "top", "bottom", "horizontal", "vertical", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.
