Description

Technical Field

[0001] This utility model relates to the field of gastric tube fixation technology, and in particular to an adjustable gastric tube fixation device for preventing pressure sores. Background Technology

[0002] A nasogastric tube is used in special circumstances to deliver essential fluids and food to patients who cannot swallow. In medical care, the secure fixation of the nasogastric tube is crucial for ensuring adequate nutrition and treatment effectiveness. Traditional methods of fixing nasogastric tubes often have several drawbacks. For example, adhesive tape fixation is prone to displacement or even dislodgement due to decreased adhesiveness caused by sweating and sebum secretion. Furthermore, prolonged tape application can irritate the skin on areas such as the nose and cheeks, leading to pressure sores and causing additional pain and infection risks. A published patent document (CN221618308 U) discloses a nasogastric tube fixator with pressure sore prevention features. This design uses a clamping component to secure the nasogastric tube, and a silicone pad prevents the connecting plate from directly contacting the patient's skin, thus reducing the risk of pressure sores. The above devices have a fixed strap connected to the connecting plate via an installation component during use, and need to be disassembled when not in use. Therefore, the structure is too cumbersome and inconvenient for quick and easy use of the fixed strap. Therefore, this application proposes an adjustable gastric tube fixator that is easy to use and has a simple structure. Summary of the Invention

[0003] The purpose of this invention is to address the problems existing in the background technology by proposing an adjustable gastric tube fixator that is easy to use and has a simple structure to prevent pressure sores.

[0004] The technical solution of this utility model is: an adjustable pressure ulcer prevention gastric tube fixator, including a fitting panel and a clamping clip, wherein a connecting piece for rotatable connection between the fitting panel and the clamping clip is provided;

[0005] The inner wall of the bonding panel is provided with a winding cavity, and a winding rod is rotatably installed in the winding cavity. Both ends of the winding rod are respectively provided with a coil spring on both sides of the inner wall of the winding cavity. The outer ring of the winding rod is also wrapped with a binding strap, and the other end of the binding strap is connected to a limiting plate larger than the inner diameter of the winding cavity.

[0006] The clamping device also includes a clamping plate rotatably mounted on the top of one end of the two mating panels, and a rubber airbag is provided on the side of the two sets of clamping plates that are close to each other.

[0007] Optionally, the card plate has an installation cavity, in which a miniature air pump is installed. The output end of the miniature air pump is connected to a delivery air pipe, and the other end of the delivery air pipe is connected to a rubber airbag.

[0008] Optionally, the outer arc surface of the rubber airbag is bonded to the arc surface of the card plate;

[0009] The miniature air pump is detachably connected to the interior of the mounting cavity, and the miniature air pump is controlled by a controller. An exhaust hole is also provided at the bottom of the card plate.

[0010] Optionally, a toggle plate is fixedly connected to one side of the top of each of the two sets of card plates.

[0011] Optionally, the surfaces of the two sets of straps are respectively connected with Velcro, and the two sets of Velcro are compatible with each other.

[0012] Optionally, the bonding panel has multiple sets of through holes extending through it.

[0013] Optionally, the bottom surface of the bonding panel is provided with an adhesive that adheres to the skin.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] This utility model, through the setting of the retractable cavity, allows for the storage of the straps when not in use, making the overall structure of the fixator more streamlined and convenient for medical staff to store and retrieve. The opening of the through hole allows the bonding panel to breathe, and the adhesive reduces the contact area between the bonding panel and the skin, thereby reducing pressure on the skin and avoiding pressure sores caused by long-term pressure.

[0016] Furthermore, the connector allows the clamp to be rotated open in the opposite direction, thus automatically springing back to hold the gastric tube after placement, achieving rapid fixation of the gastric tube. At the same time, the inflation of the rubber air bladder increases its size, making it suitable for gastric tubes of different diameters. Therefore, it is adaptable to a wide range of tubes, and the clamping size is adjustable. The inflatable rubber air bladder also prevents deformation caused by excessive pressure on the gastric tube due to hard compression, ensuring unobstructed use of the gastric tube.

[0017] In summary, this utility model has a novel and compact structure, adjustable clamping distance, wide applicability, and a simplified overall structure of the fixator, avoiding pressure sores on the patient's skin and improving patient comfort and quality of care. Attached Figure Description

A connecting member 3 is provided between the fitting panel 1 and the clamping clip 2 for rotational connection between the two. A torsion spring is provided in the connecting member 3 to spring back and close the clip 21 after it has been opened and flipped. Figure 1 The state shown;

[0034] The clamping device 2 also includes a clamping plate 21 rotatably mounted on the top of one end of the two mating panels 1. A toggle plate 22 is fixedly connected to one side of the top of each of the two clamping plates 21. An installation cavity 23 is provided in the clamping plate 21. A micro air pump 24 is installed in the installation cavity 23. The micro air pump 24 is detachably connected to the interior of the installation cavity 23 and is controlled by a controller. An exhaust hole is also provided at the bottom of the clamping plate 21. The output end of the micro air pump 24 is connected to a delivery air pipe 25.

At the same time, the soft design of the rubber air bladder 26 prevents the gastric tube from being squeezed or deformed, ensuring the normal use of the gastric tube.

[0036] Example 2

[0037] like Figures 1-4As shown, based on Embodiment 1, the bonding panel 1 has multiple through holes 12. The through holes 12 allow ventilation of the contact surface between the bonding panel 1 and the skin, reducing pressure on the skin. The bottom surface of the bonding panel 1 is provided with adhesive 11 for contact with the skin. The adhesive 11 reduces the area of ​​the adhesive part and further cushions the pressure of the bonding panel 1 on the face. The inner wall of the bonding panel 1 has a winding cavity 13. A winding rod 14 is rotatably installed in the winding cavity 13. Both ends of the winding rod 14 are connected to a coil spring 16 on each of the two inner walls of the winding cavity 13. The outer ring of the winding rod 14 is also wrapped with straps 15. The surfaces of the two sets of straps 15 are respectively connected with Velcro, and the two sets of Velcro are mutually compatible. The other end of the straps 15 is connected to a limiting plate 17 that is larger than the inner diameter of the winding cavity 13.

[0038] In this embodiment, the adhesive 11 is used to attach the bonding panel 1 to the skin. When it is necessary to fix the strap of the clamping clip 2, the limiting plate 17 is pulled to unwind the strap 15. The two sets of limiting plates 17 can be tied together or glued together with Velcro. At the same time, when not in use, the limiting plate 17 is loosened so that the strap 15 is wound up inside the winding cavity 13 by the coil spring 16.

[0039] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
