Description

Technical Field

[0001] This utility model relates to the technical field of tracheal intubation tubes, specifically a pressure ulcer prevention and fixation device for a tracheostomy cannula. Background Technology

[0002] A tracheostomy is a common surgical procedure in which the cervical trachea is cut open and a tracheostomy tube is inserted to relieve respiratory distress caused by laryngeal origin, respiratory dysfunction, or lower respiratory tract secretion retention. The tracheostomy tube is fixed to a cannula holder, which is then secured to the patient's cervical incision with a strap. During use, a tracheal pad, typically made of gauze, is placed between the cannula holder and the cervical incision; details can be found in Chinese patent document CN105498060A. Secretions such as sputum will seep from the cervical incision. When the amount of secretions is small, the tracheal pad will harden. When the amount of secretions is large, the tracheal pad becomes damp, causing the strap in contact with it to also become wet. This damp strap directly presses against the patient's neck skin, increasing the probability of pressure sores. Therefore, in the care of tracheostomized patients, the tracheal pad and strap need to be changed frequently.

[0003] Chinese patent document CN222341757U proposes a method to prevent the fixation strap from being penetrated by liquids such as sputum and sweat. The material is changed to polyester fiber, and a silicone coating is applied to its surface, giving the strap better waterproof performance. This helps keep the strap dry, avoids pressure sores caused by chafing the neck skin, reduces the frequency of strap changes, and lowers the workload of clinical nursing. Its drawbacks are: compared to cotton fixation straps, it is relatively less comfortable, and the manufacturing process is relatively more complex.

[0004] In existing technologies, common fixing straps such as Figure 1 As shown, it includes a belt body 10 and connecting belts 11 located at both ends of the belt body 10 and extending outward coaxially. The connecting belts 11 are provided with connecting components 12 for temporary fixation after the connecting belts 11 pass through the connecting holes on both sides of the sleeve seat. For details, please refer to the technical solutions described in Chinese patent documents CN219375775U and CN109966613A.

[0005] The tracheostomy cannula pressure ulcer fixation device, as described in Chinese patent document CN220757787U, consists of a cannula seat, a fixation strap, and a tracheostomy tube pad used in conjunction. Utility Model Content

[0006] The primary objective of this invention is to overcome the shortcomings of the prior art and provide a pressure ulcer fixation belt for tracheostomy cannulas that can reduce the probability of being soaked in secretions such as sputum, thereby reducing the occurrence of pressure ulcers.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] Tracheostomy cannula pressure ulcer fixation strap, including

[0009] The strap is used to secure the cannula seat to the patient's neck;

[0010] Connecting straps are located at both ends of the strap body and are used to connect the strap body to the sleeve seat; connecting components are provided on them for temporary fixation of the connecting straps after they pass through the seat fixing rings on both sides of the sleeve seat;

[0011] Also includes

[0012] An isolation sleeve is provided for each connecting strap; the isolation sleeve has a pressure surface for contacting the tracheal pad inside the cannula seat, the width of the pressure surface being greater than the width of the connecting strap; a sleeve fixing ring is provided on the opposite side of the pressure surface for the connecting strap to pass through.

[0013] The inventive concept of this invention lies in adding an isolation sleeve to each connecting strap. The pressure surface of the isolation sleeve directly contacts the tracheal cushion. Due to the compression of the tracheal cushion by the pressure surface, secretions such as sputum generally diffuse along the non-compression area. Moreover, since the connecting strap is located on the opposite side of the pressure surface, when the tracheal cushion is soaked with secretions such as sputum, the secretions are less likely to be quickly conducted to the connecting strap. Secondly, the width of the pressure surface is greater than the width of the connecting strap, increasing the contact area. Under the same clamping force, the pressure on the corresponding skin area is lower. Furthermore, due to the support of the isolation sleeve, part of the connecting strap is in a suspended state, reducing the probability of direct contact with the skin. All of the above technical effects contribute to reducing the occurrence of pressure sores.

[0014] Since the connecting belt needs to pass through the seat fixing rings on both sides of the sleeve seat and be fixed by the connecting assembly, in order to reduce the impact on the connecting assembly, the isolation sleeve is connected to the connecting belt in the form of a sleeve fixing ring.

[0015] As an improvement, the sleeve retaining ring is located on one side of the isolation sleeve to reduce its impact on the connecting components. Specifically, when the connecting components are connected using a snap-fit ​​method, the sleeve retaining ring will not be located at the connection hole.

[0016] As an improvement, the isolation sleeve has a limiting groove on the side opposite to the compression surface for limiting the position of the connecting belt. When the connecting belt is located in the limiting groove, the isolation sleeve is less likely to misalign with the connecting belt, ensuring the effectiveness of the isolation sleeve.

[0017] As a further improvement, the isolation sleeve has a protrusion on the side opposite to the compression surface. The protrusion can lift the connecting strap, reducing the probability of the connecting strap contacting the tracheal pad or the skin.

[0018] Another objective of this application is to provide a pressure ulcer fixation device for a tracheostomy cannula, comprising:

[0019] The strap is used to secure the cannula seat to the patient's neck;

[0020] Connecting straps are located at both ends of the strap body and are used to connect the strap body to the sleeve seat; connecting components are provided on them for temporary fixation of the connecting straps after they pass through the seat fixing rings on both sides of the sleeve seat;

[0021] A sleeve holder is used to fix the blast cutter tube, and a seat fixing ring is provided on both sides;

[0022] A tracheal cushion, placed inside the tracheal cannula seat, is used to absorb secretions seeping from the neck incision; it also includes...

[0023] An isolation sleeve is provided for each connecting strap; the isolation sleeve has a pressure surface that contacts the tracheal pad, and the width of the pressure surface is greater than the width of the connecting strap; a sleeve fixing ring is provided on the opposite side of the pressure surface for the connecting strap to pass through.

[0024] As an improvement, the seat fixing ring is located on the outer surface of the cannula seat. In the prior art, the seat fixing ring is located on the side of the cannula seat, and when the connecting strap passes through the seat fixing ring, a portion of the connecting strap directly contacts the tracheal cushion at the connection point with the seat fixing ring. When the seat fixing ring is located on the outer surface of the cannula seat, the connecting strap no longer directly contacts the tracheal cushion at the connection point, which helps reduce the conduction of secretions such as sputum to the connecting strap. Secondly, when adjusting the looseness of the connecting strap, since the connecting strap no longer contacts the tracheal cushion, the movement of the connecting strap on the seat fixing ring is less likely to affect the tracheal cushion, thus maintaining the flatness of the tracheal cushion.

[0025] As a further improvement, the width of the tracheal pad is less than the distance between the outer sides of the two isolation sleeves, so that there is always an isolation sleeve between the connecting strap and the tracheal pad, and the probability of the connecting strap being soaked by sputum and other secretions is further reduced.

[0026] In summary, this invention, by adding an isolation sleeve, reduces the area of ​​direct contact between the connecting strap and the tracheal cushion, which helps prevent the conduction of secretions such as sputum to the connecting strap. The isolation sleeve also keeps part of the connecting strap suspended, reducing its direct contact area with the skin and significantly lowering the probability of pressure sores. Furthermore, the fixation strap and isolation sleeve are reusable, which helps save on medical consumables. Attached Figure Description

[0034] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0035] Example 1

[0036] Commonly used tracheostomy cannula pressure ulcer fixation straps in existing technologies include Figure 1 As shown, the main body is a strap 10, made of skin-friendly fabric, with a width of 3.5cm, used to fix the cannula seat 20 to the patient's neck. Connecting straps 11 at both ends of the strap 10 are used to connect the strap 10 to the cannula seat 20, and are 1.0cm wide. The connecting component 12 uses Velcro, with hooks at the ends, each hook being 6.0cm long. After the connecting strap 11 passes through the seat fixing rings 21 on both sides of the cannula seat 20, the hooks are glued to the surface of the connecting strap 11 for temporary fixation.

[0037] This application only provides two isolation sleeves 30 on the fixing strap, such as Figure 2 As shown, each connecting band 11 corresponds to one isolation sleeve 30. The structure of the isolation sleeve 30 is as follows: Figure 3As shown, it is a long, rectangular block made of plastic. One side is a pressure surface 31 for contacting the tracheal pad 40 inside the sleeve seat 20. Several raised stripes can be provided on the pressure surface 31. The width of the pressure surface 31 is greater than the width of the connecting strap 11, which can shield the connecting strap 11 and reduce the probability of contact between the connecting strap 11 and the tracheal pad 40. A sleeve fixing ring 32 is provided on the opposite side of the pressure surface 31. The sleeve fixing ring 32 is a narrow opening for the connecting strap 11 to pass through. The sleeve fixing ring 32 is located on one side of the isolation sleeve 30.

[0038] This fixing strap is a component of the tracheostomy cannula pressure ulcer prevention and fixation device, which consists of the fixing strap, cannula seat 20, and tracheal cushion 40. The assembled state of the fixation device is as follows: Figure 4 As shown, a tracheal pad 40 for absorbing secretions seeping from the neck incision is placed inside the cannula seat 20.

[0039] The cannula seat 20 has seat retaining rings 21 on both sides for connecting the retaining strap. The tracheostomy tube 22 is located in the middle of the cannula seat 20. Unlike existing technologies, the seat retaining rings 21 of the cannula seat 20 are located on the outer surface of the cannula seat 20. When the connecting strap 11 of the retaining strap passes through the seat retaining ring 21, the portion of the connecting strap 11 that contacts the cannula seat 20 does not directly contact the tracheostomy pad 40. The movement of the connecting strap 11 within the seat retaining ring 21 does not easily affect the flatness of the tracheostomy pad 40. To completely avoid direct contact between the connecting strap 11 and the tracheostomy pad 40, the width of the tracheostomy pad 40 is less than the distance between the outer sides of the two isolation sleeves 30.

[0040] Example 2

[0041] like Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the isolation sleeve 30 has a limiting groove 33 on the side opposite to the compression surface 31 for limiting the connecting strap 11. A columnar body is provided at one end of the limiting groove 33 to form a sleeve fixing ring 32. With this design, the connecting strap 11 is embedded inside the limiting groove 33 in the use state, which not only makes it less likely to shift, but also reduces the probability of the connecting strap 11 contacting the airway pad 40.

[0042] Example 3

[0043] like Figure 6 As shown, the difference between this embodiment and Embodiment 1 is that the isolation sleeve 30 has a protrusion 34 on the side opposite to the compression surface 31, making the isolation sleeve 30 generally L-shaped. A limiting groove 33 is formed on the top of the protrusion 34. The protrusion 34 can further elevate the connecting strap 11, reducing the probability of contact between the connecting strap 11 and the tracheal pad 40 and the neck skin.
