Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary instruments, in particular to a tracheotomy cannula fixing device. Background Art

[0002] In clinical practice, tracheotomy cannulas are generally fixed to the patient's neck with gauze bands or cotton ropes. The two ends of the gauze bands or cotton ropes need to be tied in knots, which has problems of incomplete disinfection and inconvenient disinfection operations. At the same time, the gauze bands or cotton ropes have no elasticity and cannot stretch. After being used for a period of time, they are prone to hardening after being soaked by sweat and become a hard rope. Acting on the neck skin for a long time, it is inconvenient to loosen, so that the neck skin is in a compressed state for a long time, increasing the probability of skin pressure injury.

[0003] The gauze band or cotton rope generally needs to be replaced once every two or three days. Whether the connection between the gauze band or cotton rope and the tracheotomy cannula is contaminated by sputum, blood, etc., or the neck is soaked by sweat, the whole piece needs to be replaced. The connection between the gauze band or cotton rope and the tracheotomy cannula is inconvenient to disassemble, and pulling hard easily causes the plastic tracheotomy cannula to break at the drilled hole, and the tracheotomy cannula needs to be replaced again, which not only increases the workload of medical staff, but also increases the medical cost and the economic pressure on patients. Summary of the Utility Model

[0004] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the utility model is to provide a tracheotomy cannula fixing device, which effectively solves the problems of inconvenient disassembly of the existing tracheotomy cannula fixing device, affecting disinfection operations, and easily causing pressure injury to the neck.

[0005] The technical solution it adopts is that the utility model includes two fixing bands opposite to each other front and back. Two fixing buckles opposite to each other left and right are respectively fixed on the right sides of the opposite ends of the two fixing bands. The two fixing buckles opposite to each other front and back are symmetrically arranged. The fixing buckle is in the shape of "↑" and its top is a plane. A fixing hole penetrating through the front and back is opened at the free end on the left side of the fixing band, and the fixing hole can produce a slight deformation. A neck band is detachably connected to the right ends of the two fixing bands, and the width of the middle part of the neck band is greater than that of the rest part.

[0006] Compared with the prior art, the utility model has the following beneficial effects:

[0007] The utility model has a clever structure and is easy to use. By setting two fixing bands and a neck band, and setting fixing buckles, fixing holes and silicone sleeves, the two fixing bands can be first fixed on the tracheotomy cannula, and then the neck band can be fixed on the two fixing bands. The disassembly is very convenient, and the fixing band and the neck band can be disassembled separately, which is beneficial for medical staff to disinfect the tracheotomy cannula and is convenient for separately replacing the neck band, saving medical costs, having a simple structure, and being easy to popularize and use;

[0008] The fixed band is made of PVC material, and the neck band is made of breathable non-woven fabric and breathable layer. The softness of the material will not rub the patient's neck skin, and the breathable non-woven fabric can absorb sweat well, reducing the probability of neck pressure injury.

[0014] The following further describes in detail the specific embodiments of the present utility model with reference to the drawings.

[0015] It is given by Figures 1 to 5 , including two fixed bands 1 facing each other front and back. Two fixing buckles 2 facing each other left and right are respectively fixed on the right sides of the opposite ends of the two fixing bands 1. The two fixing buckles 2 facing each other front and back are symmetrically arranged. The fixing buckle 2 is in the shape of "↑" and its top is a plane. A fixing hole 3 penetrating through front and back is formed at the free end on the left side of the fixing band 1. The fixing hole 3 can produce micro-deformation. The right ends of the two fixing bands 1 are detachably connected with a neck band 4. The width of the middle part of the neck band 4 is greater than the width of the rest part.

[0016] In order to make the fixing hole 3 produce micro-deformation, the fixing band 1 is made of medical PVC material. The diameter of the fixing hole 3 is larger than the diameter of the top of the fixing buckle 2 and smaller than the diameter of the large end at the stepped surface of the fixing buckle 2.

[0017] In order to reduce the probability of neck pressure injury and increase the breathability of the neck, the neck band 4 includes two layers of breathable non-woven fabrics 5 facing each other front and back, and the two layers of breathable non-woven fabrics 5 are connected by a breathable layer 6.

[0018] In order to detachably connect the neck band 4 with the two fixing bands 1, a plurality of round holes 7 penetrating through front and back and distributed in the left-right direction are respectively formed on the two free sides of the neck band 4. A silica gel sleeve 8 is fixed in the round hole 7. The inner diameter of the silica gel sleeve 8 is larger than the diameter of the top of the fixing buckle 2 and smaller than the diameter of the large end at the stepped surface of the fixing buckle 2.

[0019] To facilitate the disassembly of the fixing strap 1 or the neck strap 4, the distance between the large end of the fixing buckle 2 and the fixing strap 1 is greater than the thickness of the fixing strap 1 or the silicone sleeve 8.

[0020] To increase the comfort of the patient during wearing, the width of the widest part of the neck strap 4 is 30 - 35 mm, and the width of the narrowest part is 10 mm.

[0021] When the present utility model is in use, an initial state is set where the neck strap 4 is not connected to the fixing strap 1, and the left free end of the fixing strap 1 is not connected to the fixing buckle 2; when it is necessary to fix the tracheotomy cannula of the patient, the left free ends of the two fixing straps 1 are respectively passed through the through holes on both sides of the tracheotomy cannula, and the fixing hole 3 is pressed on the left fixing buckle 2. During this process, the fixing hole 3 deforms and becomes larger. When the fixing hole 3 passes through the largest end of the fixing buckle 2, the fixing hole 3 is located between the stepped surface of the fixing buckle 2 and the fixing strap 1 and returns to its original state, and the two fixing straps 1 are fixed on the tracheotomy cannula.

[0022] Then, the neck strap 4 is passed around from the back of the patient's neck, so that the widest part of the neck strap 4 is located at the back of the neck. Tighten the two free ends of the two fixing straps 1 and the neck strap 4, and after adjusting the tightness (one finger can be inserted), press the two silicone sleeves 8 on the right side of the neck strap 4 on the corresponding fixing buckles 2. During this process, similar to the fixing hole 3, the silicone sleeve ring will first deform and then return to its original state, thus fixing the neck strap 4 on the two fixing straps 1, thereby realizing the fixation of the tracheotomy cannula on the patient's neck.

[0023] When it is necessary to disinfect the tracheotomy cannula, the medical staff pinches the left end of the fixing strap 1 with the index finger and thumb, bends the fixing hole 3 on the fixing strap 1 outwards, and the fixing hole 3 deforms and detaches from the fixing buckle 2. Without removing the left end of the fixing strap 1 from the tracheotomy cannula, the tracheotomy cannula and the connection between the tracheotomy cannula and the fixing strap 1 can be disinfected. Since the fixing strap 1 is made of PVC material, it has good flexibility, waterproofness, and corrosion resistance. Therefore, after disinfection, the fixing hole 3 is pressed on the corresponding fixing buckle 2, and the fixing strap 1 can be replaced together with the tracheotomy cannula.

[0024] In the present utility model, the neck strap 4 is made of non-woven fabric, which has soft comfort and good air permeability and sweat absorption functions, can increase the air permeability function of the patient's neck skin, effectively reduce the probability of pressure injury on the patient's neck, and increase the comfort of the patient. When it is necessary to replace the neck strap 4 after two or three days, the two free ends of the neck strap 4 can be simply pulled off from the fixing buckle 2. During this process, the silicone sleeve 8 will deform, and the disassembly is very convenient. Only the new neck strap 4 needs to be replaced. Since the fixing strap 1 does not need to be disassembled, it also avoids pulling the tracheotomy cannula and reduces the pain of the patient.
