Description

Technical Field

[0001] This utility model relates to the field of nursing pad technology, and in particular to a nursing pad that prevents pressure sores and is breathable for postoperative patients with heart disease. Background Technology

[0002] Cardiac surgery is a crucial treatment for various heart diseases, requiring patients to remain in bed for extended periods afterward. During this time, nursing pads are essential. These pads not only provide comfortable support but also play a vital role in preventing pressure sores. Pressure sores not only cause additional pain and prolong recovery time but can also lead to complications such as infection, threatening the patient's life and health.

[0003] However, current nursing pads on the market generally lack sufficient breathability. For post-cardiac surgery patients, prolonged bed rest leads to excessive heat and sweat buildup at the point of contact with the pad. Because existing nursing pads are not breathable enough, this heat and sweat cannot dissipate quickly, leaving the patient's skin in a warm and moist environment for extended periods. This environment is highly conducive to bacterial growth, significantly increasing the risk of pressure sores. Furthermore, non-breathable pads can cause patients to feel stuffy and uncomfortable, affecting their rest quality and negatively impacting their overall recovery process.

[0004] To improve postoperative care for heart disease patients, reduce the incidence of pressure ulcers, and enhance patient comfort, it is crucial to develop a nursing pad with excellent breathability. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the above-mentioned problem of a breathable nursing pad for preventing pressure sores after heart disease surgery, this utility model is proposed.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a breathable nursing pad for preventing pressure sores after heart disease surgery, including a base;

[0008] Several airbags are closely arranged on the base, and they have the following characteristics:

[0009] The inflation chamber is opened along the axial direction of the airbag, and its cross-section is "U" shaped. An air intake pipe for air intake is provided on one side.

[0010] The two air-dissipating chambers are symmetrically opened along the axis of the airbag and are located between the two wings of the inflation chamber. Several air vents are opened on the top wall of the chamber.

[0011] At least two T-shaped holes, each consisting of a vertical hole connecting to the inflation chamber and a horizontal hole connecting the deflation chamber and the outside of the airbag, wherein the vertical hole and the horizontal hole are interconnected.

[0012] A threaded sleeve is vertically positioned at the transverse hole location on the outside of the airbag; and

[0013] The screw is threaded into a threaded sleeve and can move axially along the threaded sleeve.

[0014] A plug is fixed to the end of the screw and extends into the horizontal hole to seal the top opening of the vertical hole;

[0015] The airbag has an inflated state and a deflated state:

[0016] When inflated, the airbag expands and comes into contact with the patient's skin by taking in air from the inflation chamber.

[0017] In the deflated state, the block is controlled by the screw to move away from the vertical hole, and the inflation chamber and the deflation chamber are connected. The gas in the inflation chamber enters the deflation chamber and is discharged from the vent to form a permeable airflow.

[0018] As a preferred embodiment of the postoperative pressure ulcer prevention and breathable nursing pad for heart disease patients described in this utility model, the ventilation holes are inclined and the opening direction is towards the middle of the air bladder.

[0019] As a preferred embodiment of the postoperative pressure ulcer prevention and breathable nursing pad for heart disease patients described in this utility model, the plurality of ventilation holes are arranged along the axial direction of the air bladder, and the arrangement density of the ventilation holes gradually increases from the edge to the center of the air bladder.

[0020] As a preferred embodiment of the postoperative pressure ulcer prevention and breathable nursing pad for heart disease patients described in this utility model, the bottom surface of the air-diffusing cavity is an inclined surface, and the gap between the inclined surface and the top surface of the air-diffusing cavity gradually decreases from the edge to the middle of the airbag.

[0021] As a preferred embodiment of the postoperative pressure ulcer prevention and breathable nursing pad for heart disease patients described in this utility model, the bottom wall of the air-diffusing cavity is provided with a plurality of guide pads, each guide pad being located below a corresponding air-permeable hole and having a slanted edge.

[0022] As a preferred embodiment of the postoperative pressure ulcer prevention and breathable nursing pad for heart disease patients described in this utility model, the base is provided with two air injection pipes on one side for connecting to an external air pump, and the air injection pipes are connected to a plurality of corresponding air inlet pipes.

[0023] The beneficial effects of this invention are as follows: Multiple closely spaced airbags provide stable support for heart disease patients. The alternating inflation of adjacent airbags dynamically adjusts the support position, effectively distributing pressure on the patient's body and significantly reducing the risk of pressure sores. Furthermore, the combination of air-draining chambers and ventilation holes guides airflow upwards when the airbags deflate, directly blowing on the patient's skin to create a breathable effect, keeping the patient's skin dry and significantly improving bed comfort, thus creating favorable conditions for the patient's overall recovery.

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0035] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale.

[0036] Reference Figures 1-6 As one embodiment of the present invention, a breathable nursing pad for preventing pressure sores after heart disease surgery is provided, which includes a base 1.

[0037] like Figures 2-5 As shown, several airbags 2 are closely arranged on the base 1. Each airbag has an inflation chamber 21, which is opened along the axial direction of the airbag 2. Its cross-section is "U" shaped. One side of the airbag 2 is provided with an air inlet pipe 51 for air intake. The base 1 is provided with two air injection pipes 5 for connecting to an external air pump. The air injection pipes 5 are connected to the corresponding multiple air inlet pipes 51. Under normal circumstances, each air injection pipe 5 is used to inflate multiple non-adjacent inflation chambers 21, so that adjacent airbags 2 can be inflated alternately, dynamically adjusting the support position, effectively dispersing the pressure on the patient's body, and greatly reducing the risk of pressure ulcer formation.

[0038] Two air-diffusing chambers 22 are symmetrically opened along the axis of the airbag 2 and located between the two wings of the inflation chamber 21. Several air vents 23 are opened on the top wall of the chambers. The air vents 23 are inclined and open towards the middle of the airbag 2. The inclined air vents 23 can direct the airflow to the patient and act directly on the patient's skin, so that the skin compressed by the airbag 2 can be fully ventilated when the airbag 2 deflates. The multiple air vents 23 are arranged along the axis of the airbag 2, and the density of the air vents 23 gradually increases from the edge to the middle of the airbag 2, which makes the airflow more concentrated and allows the patient lying in the center of the nursing pad to fully contact the airflow, further improving the ventilation effect.

[0039] The bottom surface of the air diffuser 22 is a slope, and the gap between the slope and the top surface of the air diffuser 22 gradually decreases from the edge to the middle of the airbag 2. Several guide pads 24 are provided on the bottom wall of the air diffuser 22. Each guide pad 24 is located below the corresponding air vent 23 and has a slope. The slope is aligned with the air vent 23 to guide the airflow toward the air vent 23. This, together with the slope of the air diffuser 22, guides the airflow direction and improves the ventilation effect.

[0040] At least two T-shaped holes 3, each consisting of a vertical hole connecting the inflation chamber 21 and a horizontal hole connecting the deflation chamber 22 and the outside of the airbag 2, with the vertical hole and the horizontal hole being interconnected; a threaded sleeve 4, vertically positioned at the horizontal hole position outside the airbag 2; and a screw 41, threadedly connected inside the threaded sleeve 4, which can move axially along the threaded sleeve 4; and a plug 42, fixed to the end of the screw 41, with one end extending into the horizontal hole and sealing the top opening of the vertical hole. By manually turning the screw 41, the plug 42 can be moved, thereby controlling the opening and closing state of the T-shaped holes 3 and thus controlling the deflation of the airbag 2.

[0041] Among them, airbag 2 has an inflated state and a deflated state:

[0042] When inflated, the airbag 2 is inflated by air intake through the inflation chamber 21 to expand and contact the patient's skin;

[0043] In the deflated state, the block 42 is controlled by the screw 41 to move away from the vertical hole. The inflation chamber 21 and the deflation chamber 22 are connected. The gas in the inflation chamber 21 enters the deflation chamber 22 and is discharged from the vent 23 to form a breathable airflow. The airflow blows directly on the patient's skin, creating a breathable effect, keeping the patient's skin dry, significantly improving the comfort of lying in bed, and creating favorable conditions for the patient's overall recovery.

[0044] Please see Figure 2 It should be noted that the sides of airbag 2 expand outward when inflated, creating a squeezing effect on the adjacent airbag 2, which makes the adjacent airbag 2 deflate faster and further improves the ventilation effect for the patient.

[0045] In addition, when this application is used in a cold environment, a gas at a suitable temperature (e.g., 36.5-37.5°C) should be introduced into the airbag 2 through a heated air pump so that when the airbag 2 deflates, the airflow will not irritate the patient's skin, thereby further improving the breathability and comfort.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
