The elongated body position pad for pressure injury preventive care according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1 to 6, an elongated body position cushion for pressure injury prevention and nursing according to an embodiment of the present invention includes a plurality of air bag units 10 and a fabric layer 20.

Specifically, a plurality of the airbag units 10 are sequentially arranged in the longitudinal direction, and each of the airbag units 10 extends in the lateral direction to form a strip shape and is inflatable. The fabric layer 20 covers the plurality of airbag units 10, and the fabric layer 20 may be made of cloth, leather, or other soft fabrics.

Each of the airbag units 10 includes an inner airbag 101 and an outer airbag 102, the inner airbag 101 has a first inflation interface 1011, and the outer airbag 102 has a second inflation interface 1021, that is, the airbag unit 10 is designed as a double-layer airbag structure formed by the inner airbag 101 and the outer airbag 102, and the inner airbag 101 and the outer airbag 102 are inflated independently, that is, the inner airbag 101 is inflated through the first interface, and the outer airbag 102 is inflated through the second interface, so that the hardness of the inner airbag 101 and the hardness of the outer airbag 102 can be adjusted independently.

According to the embodiment of the utility model provides an elongated position pad for pressure nature damage prevention nursing has a plurality of gasbag units 10 of arranging in proper order along vertically to and the precoat 20 of parcel in gasbag unit 10 outside, on the one hand, utilize a plurality of gasbag units 10 to aerify and can provide hardness adjustable support, on the other hand, conveniently fold and form different forms in order to adapt to different positions, in addition, every gasbag unit 10 adopts the bilayer structure of inlayer gasbag 101 and outer gasbag 102, and inlayer gasbag 101 has first inflation interface 1011, outer gasbag 102 has second inflation interface 1021, so, can aerify respectively, so to the different regulation to the hardness of gasbag unit 10 inside and outside, for example inlayer gasbag 101 hardness is big, and outer gasbag 102 hardness is little, when guaranteeing the support nature, is difficult to shift.

In an embodiment of the present invention, a plurality of the airbag units 10 have a predetermined gap therebetween, the surface of the fabric layer 20 is provided with a first magic tape 21 and a second magic tape 22, the first magic tape 21 is located at one end of the fabric layer 20, and the second magic tape 22 is located at the other end of the fabric layer 20 and extends toward the first magic tape 21. When the elongated body position pad is folded along the longitudinal direction, the first magic tape 21 can be selectively adhered to different positions of the second magic tape 22.

Because the gaps are formed among the air bag units 10, and the fabric layer 20 wraps the outer portions of the air bag units 10, the formed body position cushion can be turned over along the longitudinal direction, and the gap between any two adjacent air bag units 10 is a folding position, so that the body position cushion can be turned over as required, body position cushions with different thicknesses and different forms are formed, different body position requirements are met, and the turning over is convenient. In addition, after the folding, the first hook and loop fastener 21 and the second hook and loop fastener 22 can be used for bonding, so that the folded posture pad is kept in a folded state for convenient use.

In some embodiments of the present invention, at least one exhalation valve 103 is disposed on the inner airbag 101, and the exhalation valve 103 is configured to open when the pressure in the inner airbag 101 is greater than a predetermined pressure, so that the gas in the inner airbag 101 is discharged to the outer airbag 102 through the exhalation valve 103.

When the body position cushion is inflated, when the pressure of gas filled in the inner layer air bag 101 reaches a preset pressure, the expiratory valve 103 is opened, and the gas in the inner layer air bag 101 flows into the outer layer air bag 102, so that the maximum hardness of the inner layer air bag 101 can be limited, and the excessive hardness of the inner layer air bag 101 is avoided. In addition, in the use of the body position cushion, if the hardness of the outer layer air bag 102 is too low, so that a patient can extrude the inner layer air bag 101 when using the body position cushion, the expiratory valve 103 is opened, the gas in the inner layer air bag 101 is discharged to the outer layer air bag 102, so that the gas in the outer layer air bag 102 is relatively increased, the hardness of the outer layer air bag 102 is improved to a certain extent, the hardness of the inner layer air bag 101 is reduced, and the hardness is relatively balanced.

In one embodiment of the present invention, the exhalation valve includes a valve housing, a valve element 1033, and an elastic member 1034, wherein the valve housing is embedded in the inner airbag, and the valve housing has an exhalation vent H103b communicating the inner airbag 101 and the outer airbag 102. A valve element 1033 is slidably disposed on the valve housing and is switchable between the closed state and the open state.

A resilient member 1034 is disposed between the valve element 1033 and the valve housing to provide a resilient force to force the valve element 1033 to be in the closed state, in which the valve element 1033 closes the exhalation port H103 b; when the pressure in the inner bag 101 is higher than a predetermined pressure, the valve element 1033 is slidably switched to the open state against the elastic force, and in the open state, the valve element 1033 opens the exhalation vent H103 b.

That is, valve element 1033 is slidable on the valve housing, and elastic member 1034 is disposed between valve element 1033 and the valve housing to provide an elastic function to valve element 1033, so that valve element 1033 is kept closed by the elastic function of elastic member 1034 to allow exhalation vent H103b to be connected when no other external force is introduced, and inner bladder 101 and outer bladder 102 are independent of each other and keep different hardness. When the pressure of the inner airbag 101 is greater than a predetermined pressure, for example, over-inflated or squeezed, the valve element 1033 slides under the pressure of the gas in the inner airbag 101, and is switched to an open state, so that the exhalation vent H103b is opened, and the gas in the inner airbag 101 can be discharged into the outer airbag 102, thereby balancing the internal pressure and the external pressure.
