DETAILED DESCRIPTION

[0020] The specific embodiments of the present application will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present application, but does not constitute a limitation on the present application. In addition, the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0021] As Figures 1-5 shown:

[0022] The device is composed of a cheek fixing base 1, a nasogastric tube locking clamp 3 and an elastic connecting belt 2. The cheek fixing base 1 serves as the force bearing basis of the entire device, dispersing the pulling force of the nasogastric tube to a larger area of the face. The elastic connecting belt 2 is used to connect the cheek fixing base 1 and the nasogastric tube locking clamp 3, which is the essence of the design. When the nasogastric tube is accidentally pulled, the system can absorb energy and provide a buffer to avoid the pulling force acting directly on the nostrils or causing the device to fall off. The nasogastric tube locking clamp 3 is used to firmly hold the nasogastric tube to prevent it from moving up and down and left and right, but at the same time cannot be flattened or damaged.

[0023] The cheek fixing base 1 is made of medical grade PU foam or hydrocolloid dressing, which has the characteristics of extremely soft, breathable and waterproof, and can improve the comfort of the patient. The shape is a projection of an ellipse and a lateral projection of a circular arc, which is more suitable for the curvature of the face, and is beneficial to fit and disperse stress.

[0024] A buckle interface is fixed in the middle of the outside of the cheek fixing base 1, and the inside is a bonding layer 133. The elastic connecting belt 2 is connected to the buckle joint 11 and the nasogastric tube locking clamp 3 at both ends, respectively. Multiple positioning holes 21 are provided on the elastic connecting belt 2 near the cheek fixing base 1, which are fixed through the positioning holes 21 and the buckle interface, so as to adjust the length of the elastic connecting belt 2, allowing nurses to accurately adjust the length according to the patient's face shape, ensuring that the buffer system is in the best working condition. The elastic connecting belt 2 can be made of medical silicone or special elastic fabric.

[0025] The bonding layer 133 can be made of medical pressure-sensitive adhesive + non-woven paper, which is the most mainstream way. The glue needs to be waterproof, breathable, low sensitivity, or use low sensitivity medical acrylic adhesive with release paper. The cheek fixing base 1 is reusable, while the adhesive part is disposable, reducing costs.

[0026] As an optimization design, the buckle joint 11 is composed of a clamping head and a cover plate 12, the clamping head is provided with a clamping groove A111 on the top surface, the clamping groove A111 is provided with a clamping groove B112 at the bottom, the width and depth of the clamping groove A111 are consistent with the cover plate 12 and are greater than the clamping groove B112, the width and depth of the clamping groove B112 are consistent with the elastic connecting band 2, at least one protruding positioning post 113 corresponding to the spacing of the positioning holes 21 is arranged at the bottom of the clamping groove B112 and protrudes to the top surface of the clamping groove A111, the cover plate 12 is provided with clamping holes 121 corresponding to the positions of the positioning posts 113, the elastic connecting band 2 is pressed into the clamping groove A111 according to the adjustment length, the corresponding positioning holes 21 are pressed into the positioning posts 113 in the clamping groove A111, then the clamping holes 121 of the cover plate 12 are aligned with the positioning posts 113 and are pressed into the cover plate 12, and the arc-shaped pulling piece 122 of the cover plate 12 protrudes from the clamping head, so that the cover plate 12 can be disassembled and the elastic connecting band 2 can be taken out by pinching the arc-shaped pulling piece 122 when disassembled.

[0027] The nasogastric tube locking clamp 3 can adopt the following structure

[0028] (1) Flexible clamping buckle / clamping groove, made of silica gel or soft plastic, the clamping groove with protrusions is used to "hug" the nasogastric tube by the elasticity of the material.

[0029] (2) Knob locking mechanism: by rotating a knob, the internal soft pad is tightened, suitable for different pipe diameters.

[0030] (3) Magic tape: a soft tape is used to fix the pipeline on the base.

[0031] The present application provides a specific design scheme, the nasogastric tube locking clamp 3 is composed of a semicircular outer tube clamp 32 and an inner tube clamp 31, a deformation seam 33 is reserved in the middle, the deformation seam 33 can cause a certain extrusion to the nasogastric tube when the outer tube clamp 32 and the inner tube clamp 31 are folded, in order to reduce the operation difficulty, the combination part 33 is outwardly protruding on both sides of the outer tube clamp 32 and the inner tube clamp 31, a plurality of clamping strips 35 are protruding on the surface of the combination part 33 of the inner tube clamp 31, a plurality of clamping holes 36 are arranged at the positions corresponding to the clamping strips 35 of the combination part 33 of the outer tube clamp 32, the outer tube clamp 32 and the inner tube clamp 31 can be quickly buckled together by pressing.

[0032] At the same time, silica gel pads 37 are bonded on the inner walls of the outer tube clamp 32 and the inner tube clamp 31, and anti-skid lines 38 are arranged on the surface of the silica gel pads 37, so that the clamping force can be effectively improved, and damage or large deformation of the nasogastric tube can be avoided, the anti-skid lines 38 can be a plurality of parallel triangular notches or trapezoidal notches, since the outer tube clamp 32 and the inner tube clamp 31 are separated, the elastic connecting band 2 and the inner tube clamp 31 are integrated.

[0033] Use process:

[0034] (1) Clean and dry the skin of the patient's cheek fixation area.

[0035] (2) Tear off the release paper or non-woven base paper of the cheek fixation base 1 and attach it flat to the cheekbone.

[0036] (3) Pre-fix the nasogastric tube with tape for the first time, then place the nasogastric tube 5-8 cm below into the "nasogastric tube locking clamp 3" for fixation.

[0037] Adjust the length of the "elastic connecting belt 2" so that the nasogastric tube is tension-free in a natural state and has a slight curvature. Then the elastic connecting belt 2 is connected with the buckle interface, so that when pulled, the elastic connecting belt 2 will still not be pulled to the first fixed position under the condition of being stretched under force.

[0038] The embodiments of the present application are described in detail above in combination with the drawings, but the present application is not limited to the described embodiments. For those skilled in the art, various changes, modifications, replacements and variations of these embodiments can be made without departing from the principles and spirits of the present application, and still fall within the protection scope of the present application.
