Description

Technical Field

[0001] This application belongs to the field of medical device technology, specifically relating to a fixation structure for a tracheal cannula. Background Technology

[0002] The tracheostomy tube is mainly installed in the larynx of patients undergoing tracheostomy. It is used to fix the endotracheal tube, seal the tracheal gap, prevent tracheal displacement, and create a relatively closed space to ensure unobstructed airflow and maintain normal respiratory function. After the tracheostomy tube is installed in the patient's larynx, it needs to be fixed to ensure its effective fixation of the trachea.

[0003] In related technologies, the tracheostomy tube fixation strap includes a fixation strap body and straps connected to both ends of the fixation strap body. The fixation strap body is used to wrap around the back of the patient's neck, and the straps are used to connect to the tracheostomy tube inserted into the patient's larynx. However, the connection strength between the straps and the fixation strap body is relatively low. After the straps are connected to the tracheostomy tube, when the tracheostomy tube or the fixation strap is subjected to force, the straps are prone to detaching from the fixation strap body, affecting the fixation effect on the tracheostomy tube. Utility Model Content

[0004] This application aims to provide a fixing structure for tracheostomy tubes to solve the problem of low connection strength between the existing fixing strap body and the strap.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] This application discloses a fixing structure for a tracheostomy tube, comprising: a main body and two straps, wherein the main body includes two opposite ends, and the two straps are respectively connected to the two ends of the main body; wherein,

[0007] A fixing piece is embedded at the end of the main body, and the strap extends into the main body and is connected to the fixing piece. The end of the strap away from the main body is used to connect to the tracheostomy tube.

[0008] Optionally, the end of the main body is provided with a mounting cavity and a connecting hole. The mounting cavity is connected to the outside of the main body through the connecting hole. The fixing piece is connected in the mounting cavity, and the strap passes through the connecting hole and is connected to the fixing piece.

[0009] Optionally, along the width direction of the body, the size of the connecting hole is smaller than the size of the fixing piece.

[0010] Optionally, the fixing piece is provided with a strap hole, and the strap is connected to the strap hole.

[0011] Optionally, the number of strap holes is multiple, and the multiple strap holes are spaced apart along the width direction of the body.

[0012] Optionally, the strap includes a main fixing strap and a support fixing strap. The main fixing strap is connected to the tracheostomy tube, and the support fixing strap is connected to the fixing plate. There are multiple support fixing straps, with one end of each strap spaced apart along the width of the main body and the other end connected to the main fixing strap.

[0013] Optionally, the main fixing strap is provided with a first connecting portion, the supporting fixing strap is provided with a second connecting portion, and the strap includes a first side and a second side that are opposite to each other, with the first connecting portion and the second connecting portion located on the same side of the strap.

[0014] Optionally, the first connecting part is one of a male Velcro strap and a female Velcro strap, and the second connecting part is the other of a male Velcro strap and a female Velcro strap.

[0015] Optionally, the main body is a rubber belt.

[0016] Optionally, the cross-section of the main body along the width direction is elliptical.

[0017] In this embodiment, a fixing piece is provided at the end of the main body, which can provide a connection point for the connection between the strap and the main body. Since the fixing piece is embedded in the main body, the connection between the fixing piece and the main body is more reliable. Thus, when the strap is connected to the fixing piece, the connection strength between the strap and the main body can be enhanced, effectively preventing the strap from falling off the main body during use and ensuring the fixation effect of the tracheostomy tube.

[0030] This application provides a fixation structure for a tracheostomy tube. Specifically, this fixation structure can be used to fix a tracheostomy tube inserted into the larynx of a tracheostomy patient. According to the fixation structure for a tracheostomy tube provided in this application, the connection strength between the strap and the main body is relatively good, which can ensure the fixation effect of the fixation structure on the tracheostomy tube.

[0031] The following description, in conjunction with the accompanying drawings and specific embodiments, provides a more detailed explanation of the fixing structure for the tracheal cannula provided in the embodiments of this application.

[0032] It should be noted that, in the embodiments of this application, as Figures 1 to 4 As shown, the width of the main body is in the direction indicated by arrow x, the length of the main body is in the direction indicated by arrow y, and the length of the main body is in the direction indicated by arrow z.

[0033] like Figures 1 to 3 As shown, the fixing structure for the tracheostomy tube includes: a main body 10 and two straps 20. The main body 10 includes two opposite ends, and the two straps 20 are respectively connected to the two ends of the main body 10. A fixing piece 11 is embedded in the end of the main body 10, and the straps 20 extend into the main body 10 and are connected to the fixing piece 11. The end of the straps 20 away from the main body 10 is used to connect the tracheostomy tube.

[0034] Specifically, the main body 10 can serve as a support part of the fixation structure for the tracheostomy tube and is wrapped around the patient's neck. One end of the strap 20 is connected to the end of the main body 10 along its length, and the other end is connected to the tracheostomy tube. The fixation piece 11 can be made of a material with a certain degree of hardness, such as a stainless steel fixation piece 11 or a plastic fixation piece 11. The fixation piece 11 can be formed by hot-pressing injection molding with the main body 10, or the fixation piece 11 can be installed into the main body 10 afterward. This application does not make specific limitations in this regard.

[0035] Furthermore, since the main body 10 and the strap 20 are connected by the fixing piece 11, the main body 10 and the strap 20 can be made of different materials to meet different usage needs. For example, the main body 10 can be made of elastic materials such as rubber or silicone, which can reduce the pressure of the main body 10 on the patient's neck and prevent the patient from feeling uncomfortable during use. The strap 20 can be made of nylon or polyester webbing. It should be noted that this non-elastic strap 20 structure can provide a more stable connection strength, which helps to improve the fixation effect of the tracheostomy tube.

[0036] In practical applications, a tracheostomy tube includes a cannula and a chuck connected to the end of the cannula. The cannula can be inserted into the patient's larynx. After the cannula is inserted into the patient's larynx, the chuck is locked outside the patient's larynx. The left and right sides of the chuck are usually provided with through holes for connecting to a fixing strap. The fixing strap can pass through the through holes and connect to the tracheostomy tube.

[0037] According to the tracheostomy tube fixing structure provided in the embodiments of this application, the main body 10 can be wrapped around the back of the patient's neck so that the two ends of the main body 10 are located on the left and right sides of the patient's neck, and then the straps 20 at both ends of the main body 10 are passed through the through holes on both sides of the tracheostomy tube clamp, and then wrapped back to one side of the fixing structure and the straps 20 are fixed.

[0038] In one embodiment of this application, the end of the main body 10 is provided with a mounting cavity 12 and a connecting hole 13. The mounting cavity 12 is connected to the outside of the main body 10 through the connecting hole 13. The fixing piece 11 is connected in the mounting cavity 12, and the strap 20 passes through the connecting hole 13 and is connected to the fixing piece 11.

[0039] Specifically, such as Figure 4 , Figure 5 As shown, the fixing piece 11 has a roughly rectangular structure and a certain thickness. The mounting cavity 12 has the same shape and structure as the fixing piece 11. Since the fixing piece 11 is a rigid structure, the size of the mounting cavity 12 can be designed to be slightly smaller than that of the fixing piece 11. This allows the fixing piece 11 to be interference-fitted into the mounting cavity 12, resulting in a tighter connection between the fixing piece 11 and the main body 10, preventing the fixing piece 11 from falling out of the mounting cavity 12. Furthermore, after the fixing piece 11 is assembled into the mounting cavity 12, adhesive can be injected to ensure the connection strength between the fixing piece 11 and the mounting cavity 12. When the size of the mounting cavity 12 is designed to be slightly larger than that of the fixing piece 11, adhesive can also be injected directly into the mounting cavity 12. In this case, a larger amount of adhesive can be injected, and after the adhesive cures, it can tightly connect the fixing piece 11 to the inner wall of the mounting cavity 12. For example, the adhesive can be a light-curing adhesive such as UV adhesive; this application does not specifically limit the type of adhesive used.

[0040] The number of connecting holes 13 can be one or more. When there is only one connecting hole 13, the size of the connecting hole 13 along the width direction of the main body 10 can be designed to be larger to ensure that the force on both sides of the strap 20 can be more even. When there are multiple connecting holes 13, the strap 20 can have multiple ends and pass through multiple connecting holes 13 respectively.

[0041] The strap 20 can be bonded to the fixing piece 11 after passing through the connecting hole 13, or the fixing piece 11 can be provided with mounting holes for the strap 20 to be threaded through.

[0042] In one embodiment of this application, the size of the connecting hole 13 is smaller than the size of the fixing piece 11 along the width direction of the main body 10.

[0043] It should be noted that the fixing piece 11 is connected inside the mounting cavity 12. The mounting cavity 12 is connected to the outside of the main body 10 through the connecting hole 13. When the dimension of the connecting hole 13 along the width direction of the main body 10 is smaller than the dimension of the fixing piece 11, it can limit the fixing piece 11, thereby effectively preventing the fixing piece 11 from falling out of the mounting cavity 12.

[0044] In one embodiment of this application, the fixing piece 11 is provided with a strap hole 111, and the strap 20 is connected to the strap hole 111.

[0045] Specifically, the strap hole 111 is a strip-shaped hole, with its length direction along the width direction of the main body 10, and its size is adapted to the size of the strap 20. The strap hole 111 allows the strap 20 to pass through. The end of the strap 20 can pass through the strap hole 111 from one side of the fixing piece 11 and be pulled back from the other side to be sewn to the middle of the strap 20. It can be understood that this method of the end of the strap 20 passing through the strap hole 111 and being pulled back to be sewn to the middle of the strap 20 can improve the connection strength between the strap 20 and the fixing piece 11.

[0046] Optionally, there may be multiple strap holes 111, which are spaced apart along the width direction of the main body 10.

[0047] Specifically, the number and position of the strap holes 111 are adapted to the number and position of the connecting holes 13 of the main body 10. The strap 20 can have multiple ends on the side near the main body 10. One end of the strap 20 passes through a connecting hole 13 and through the strap hole 111 on the fixing plate 11 from one side, and then passes out of the connecting hole 13 from the other side to the outside of the main body 10, and is fixed to the part of the strap 20 away from the main body 10. In practical applications, when multiple strap holes 111 are provided, the size of each strap hole 111 along the width direction of the main body 10 can be designed to be smaller, and the end of the strap 20 can also be designed to be narrower. This can effectively prevent the strap 20 from wrinkling and piling up in the strap hole 111, ensuring the flatness of the strap 20. Moreover, since each strap hole 111 can pass through one end of the strap 20, the force on the main body 10 along the width direction is more even.

[0048] In one embodiment of this application, the strap 20 includes a main strap 21 and a support strap 22. The main strap 21 is connected to the tracheostomy tube, and the support strap 22 is connected to the fixing piece 11. There are multiple support straps 22, with one end of each support strap 22 spaced apart along the width direction of the main body 10, and the other end connected to the main strap 21.

[0049] Specifically, the width of the main fixed strap 21 is greater than the width of the fixed support strap 22. The multiple fixed support straps 22 pass through the multiple strap holes 111 of the fixed piece 11 respectively. The ends of the multiple fixed support straps 22 that are away from the main body 10 converge to the main fixed strap 21 and are connected to the main fixed strap 21 at the same time.

[0050] Furthermore, the main fixing strap 21 is provided with a first connecting portion 23, the supporting strap 22 is provided with a second connecting portion 24, and the strap 20 includes a first side and a second side that are opposite to each other. The first connecting portion 23 and the second connecting portion 24 are located on the same side of the strap 20. In practical applications, the main fixing strap 21 can pass through the through hole on the tracheostomy tube clamp and be pulled back until the first connecting portion 23 on the main fixing strap 21 and the second connecting portion 24 on the supporting strap 22 are at least partially opposite, connecting the first connecting portion 23 to the second connecting portion 24, thereby achieving the fixation between the strap 20 and the tracheostomy tube.

[0051] For example, the first connecting part 23 can be one of the male or female buckles in a double snap fastener, and the second connecting part 24 can be the other of the male or female buckles in a double snap fastener, so that the fixing main strap 21 and the fixing support strap 22 can be fastened together. Alternatively, the first connecting part 23 can be one of the male and female Velcro fasteners, and the second connecting part 24 can be the other of the male and female Velcro fasteners, so that the fixing main strap 21 and the fixing support strap 22 can be bonded together.

[0052] In one embodiment of this application, the first connecting part 23 is one of a male Velcro strap and a female Velcro strap, and the second connecting part 24 is the other of a male Velcro strap and a female Velcro strap. For example, a female Velcro strap is provided on the main fixing strap 21, and a male Velcro strap is provided on the support strap 22. The main fixing strap 21 can pass through the through hole on the tracheostomy tube clamp and be pulled back until the female Velcro strap on the main fixing strap 21 attaches to the male Velcro strap on the support strap 22, thereby fixing the tracheostomy tube.

[0053] Specifically, the fixing plate 11 has two strap holes 111, the main body 10 has two connecting holes 13 at its end, and the fixing straps 22 are two in total. One end of each fixing strap 22 is sewn to the main fixing strap 21, and the other end passes through the two connecting holes 13 and the two strap holes 111 respectively, and is pulled back to the outside of the main body 10 to be sewn to the fixing strap 22. The two fixing straps 22 form a V-shaped structure on one side of the main fixing strap 21. The end of the main fixing strap 21 away from the fixing strap 22 is used to pass through the chuck on the tracheostomy tube and is pulled back to connect with the fixing strap 22. The main fixing strap 21 and the fixing strap 22 are connected by Velcro.

[0054] In one embodiment of this application, the main body 10 is a rubber band. In practical applications, the rubber band can deform under stress, thereby offsetting part of the external force when the fixed structure is subjected to external force. Furthermore, because the rubber band has a certain degree of elasticity, it can avoid putting pressure on the patient's neck and reduce patient discomfort.

[0055] Furthermore, a cushioning pad can be provided on the surface of the main body 10. The cushioning pad can be made of a soft, sweat-absorbing flexible material, such as non-woven fabric, gauze, or cotton cloth, to absorb sweat and prevent the main body 10 from adhering to the patient's neck skin.

[0056] Optionally, the cross-section of the main body 10 along the width direction is elliptical. When the tracheostomy patient is supine, the main body 10 contacts the skin of the back of the patient's neck. When the cross-section of the main body 10 is designed to be elliptical, the two sides of the main body 10 along the width direction have rounded corners, which can avoid the sharp edges of the main body 10 along the width direction from pressing on the patient's neck skin and causing ligature marks on the patient's neck, thus improving comfort.

[0057] In summary, the fixing structure for the tracheostomy tube according to the embodiments of this application can include at least the following advantages:

[0058] In this embodiment, a fixing piece is provided at the end of the main body, which can provide a connection point for the connection between the strap and the main body. Since the fixing piece is embedded in the main body, the connection between the fixing piece and the main body is more reliable. Thus, when the strap is connected to the fixing piece, the connection strength between the strap and the main body can be enhanced, effectively preventing the strap from falling off the main body during use and ensuring the fixation effect of the tracheostomy tube.
