Description

Technical Field

[0001] This utility model relates to the field of medical and nursing technology, and in particular to a protective fixation device for a tracheostomy cannula for children. Background Technology

[0002] Tracheostomy is a common procedure in the treatment of critically ill children. It is an invasive procedure that involves percutaneously cutting open the cervical trachea and inserting a tracheostomy tube to establish an artificial airway. Compared with prolonged tracheal intubation and mechanical ventilation, the advantages of tracheostomy include reduced sedation requirements, ease of fixation and safety, smaller anatomical dead space, lower airway resistance, easier suctioning and drainage of secretions and oropharyngeal care, increased patient comfort, easier weaning from mechanical ventilation, and preservation of swallowing function, which can lead to early resumption of oral feeding.

[0003] Currently, the clinical care of tracheostomy tubes is quite cumbersome. Gauze ties or cotton ropes are used to secure the tubes around the neck, often tied manually in a knot. This can lead to loosening or excessive tightness of the knots, causing the tracheostomy tube to shift or dislodge, or damaging the surrounding skin. This is especially problematic for children who require long-term breathing exercises with the tracheostomy tube in place. Wearing thin gauze ties for extended periods can cause significant friction on the child's neck. Children's skin is delicate, and they are less cooperative when crying, making them more susceptible to pressure sores, rashes, and other skin problems. The gauze pad placed between the wound and the tube is inconvenient to change when contaminated with sputum, sweat, or saliva, requiring two people to operate. Carelessness can also lead to tube dislodgement. Furthermore, the securing straps are prone to curling and narrowing. Patient sweating and tracheostomy site seepage can cause the straps to become damp, leading to pressure sores, eczema, or even skin breakdown in children. These issues result in inconvenient operation, difficulty in adjusting the securing length, and poor comfort after tracheostomy. Therefore, optimizing and improving the postoperative care of these children after tracheostomy is particularly important. Utility Model Content

[0004] This utility model provides a child tracheostomy sleeve protection and fixation device. The fixation device is easy to install and adjust, has strong stability and good comfort, and can be adjusted according to the different neck sizes of children.

Detailed Implementation

[0026] The following is in conjunction with the appendix Figure 1-7 The present invention will be described in further detail below.

[0027] like Figure 1As shown, a child tracheostomy tube protective fixation device includes a fixation strap 1. The fixation strap 1 includes a fixation strap body 2 that fits against the neck of the human body and guide straps 3 that are fixed to both ends of the fixation strap body 2. The end of the guide strap 3 is provided with a connecting part 4 that can be detachably connected to the tracheostomy tube 6. The fixation strap body 2 is provided with a plurality of flexible support pieces 5 that fit against the neck of the human body.

[0028] like Figure 1 , 2 As shown, the flexible support piece 5 is rectangular, and a through groove 51 is provided in the middle of the flexible support piece 5. A dividing strip 52 is provided in the center of the through groove 51, dividing the through groove 51 into a left through groove 511 and a right through groove 512. The height of the through groove 51 is adapted to the width of the fixing strap body 2. The fixing strap body 2 passes through the left through groove 511 and the right through groove 512 of the flexible support piece 5. In this embodiment, the fixing strap body 2 passes through the left through groove 511 and the right through groove 512 of the flexible support piece 5, and the dividing strip 52 is located on the outer surface of the fixing strap body 2.

[0029] By setting several flexible support pieces 5 on the fixing strap body 2, the fixing strap body 2 can be prevented from curling and narrowing during use, ensuring that the inner side of the fixing strap body 2 always faces the human neck, avoiding ligature marks on the neck, improving the comfort of children, and enhancing the stability of the tracheostomy tube on the tracheostomy sleeve 6.

[0030] In order to avoid the hard compression of the neck caused by the upper and lower ends of the flexible support plate 5 and improve the comfort of the neck, the upper and lower ends of the flexible support plate 5 are provided with buffer parts 53 extending obliquely outward and upward and obliquely outward and downward, respectively. The buffer parts 53 and the flexible support plate 5 are smoothly transitioned and integrally formed.

[0031] like Figure 5 As shown, the fixing strap 1 in this embodiment includes a polyurethane layer 11, a spunlace nonwoven fabric layer 12 and a backing base 13 connected in sequence. The polyurethane layer 11 is located on the inner side of the fixing strap 1 and faces the skin of the human neck. The fixing strap 1 is provided with a plurality of ventilation holes 14.

[0032] The polyurethane layer 11 is soft and skin-friendly, reducing discomfort for patients during use. The spunlace nonwoven fabric layer 12 has super water absorption capacity. The backing 13 can be made of cotton cloth, PE film, PU film, nonwoven fabric, elastic fabric, etc.

[0033] Children are prone to sweating when wearing the support strap 1 for extended periods. Sweat can enter the spunlace nonwoven fabric layer 12 through the ventilation holes 14 and be absorbed. The ventilation holes 14 can also accelerate the evaporation of sweat in the spunlace nonwoven fabric layer 12 and the sweat on the neck.

[0034] The width of the fixing belt body 2 is greater than the width of the guide belt 3, and there is a smooth transition between the fixing belt body 2 and the guide belt 3.

[0035] The wider fixing strap 1, used in conjunction with the flexible support plate 5, can prevent the fixing strap body 2 from curling and narrowing during use, thus preventing the narrowed fixing strap body 2 from causing marks on the neck. The fixing strap body 2 and the guide strap 3 have a smooth transition, which can avoid the sharp edges of the fixing strap body 2 and the guide strap 3 from causing scratches or discomfort to the skin.

[0036] like Figure 3 As shown in Embodiment 1, the connecting part 4 includes a male Velcro 41 provided at the outer end of the guide band 3, and a female Velcro 42 provided along the length direction of the outer side of the guide band 3, which is separated from the male Velcro 41.

[0037] like Figure 1 As shown, the inner surface of the guide strap 3 faces the human neck and passes outward from the inside of the fixing groove on the side of the tracheostomy sleeve 6. Then, the male hook and loop fastener 41 is attached to the female hook and loop fastener 42 at the appropriate position according to the thickness of the neck, so that the circumference of the fixing strap 1 can be adjusted to meet the needs of children with different neck sizes.

[0038] like Figure 4 , 6 As shown in Embodiment 2, the connecting part 4 includes an adhesive layer 43 disposed on the outer surface of the guide strip 3. The adhesive layer 43 includes an outer adhesive layer 431 and an inner adhesive layer 432. The outer adhesive layer 431 and the inner adhesive layer 432 are separated by a non-adhesive area 433. The outer adhesive layer 431 is close to the end of the guide strip 3. Both the outer adhesive layer 431 and the inner adhesive layer 432 are covered with release paper 44.

[0039] like Figure 7 As shown, the inner surface of the guide strap 3 faces the neck of the human body and passes outward from the inside of the fixing groove on the side of the tracheostomy sleeve 6. Then, determine the appropriate position of the outer adhesive layer 431 to the inner adhesive layer 432 according to the thickness of the neck. Remove the release paper 44 on the outer adhesive layer 431 and the inner adhesive layer 432, and stick the outer adhesive layer 431 on the inner adhesive layer 432. This makes the circumference of the fixing strap 1 adjustable to meet the needs of children with different neck sizes.

[0040] like Figure 6 , 7 As shown, to facilitate adjustment of the circumference of the fixing band 1 or replacement of the fixing band 1, the end of the guide band 3 is provided with an outwardly extending peeling head 31. The outer surface of the peeling head 31 does not have an adhesive layer 43. When it is necessary to adjust the circumference of the fixing band 1 or replace the fixing band 1, pull the peeling head 31 to separate the outer adhesive layer 431 and the inner adhesive layer 432. After re-determining the relative position between the outer adhesive layer 431 and the inner adhesive layer 432, they can be re-adheded.

[0041] To facilitate adjustment of the relative position between the outer adhesive layer 431 and the inner adhesive layer 432, the outer adhesive layer 431 includes multiple strip-shaped adhesive layers 43 extending along the length direction of the guide strip 3, and the multiple strip-shaped adhesive layers 43 are parallel to each other.

[0042] The outer adhesive layer 431 is configured as multiple parallel strip adhesive layers 43, which ensures sufficient adhesive force when it is adhered to the inner adhesive layer 432, and also facilitates separation from the inner adhesive layer 432, making it convenient to adjust the circumference of the fixing band.

[0043] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
