Description

Technical Field

[0001] This utility model belongs to the field of tracheostomy tube fixation technology, specifically, it relates to an adjustable fixation device for tracheostomy. Background Technology

[0002] A tracheotomy, also known as a tracheotomy, is a procedure in which a small incision is made in the trachea to improve breathing. When a patient with respiratory failure cannot be weaned off the ventilator in a short period of time, the doctor will recommend that he undergo a tracheotomy. Although the procedure is simple, the risk of the surgery is increased due to the patient's original physical condition and the possibility of complications during or after the surgery.

[0003] In the prior art, patent announcement number CN207041716U, patent announcement date: 2018-02-27, entitled "An Adjustable Fixation Device for Tracheostomy," discloses an adjustable fixation device for tracheostomy, including a pressure plate. A frame is embedded in the middle of the pressure plate through a groove. A locking device is elastically connected inside the frame. The two sides of the frame are respectively fixedly installed to one end of a first fixing strap and a second fixing strap. The other end of the first fixing strap is locked to the other end of the second fixing strap through a fixedly installed locking device. This utility model has the advantages of being adjustable within a certain range to adapt to wounds of different sizes, preventing incorrect size selection, avoiding wasted time, reducing costs, and eliminating the need for manufacturers to produce different sizes of fixation sleeves (only one size is needed). It is highly practical, easy to produce, and can be mass-produced. It can be adjusted according to the patient's neck to accommodate different neck diameters, providing both secure fixation and comfort.

[0004] While the aforementioned patents can fix different types of tracheostomy cannulas, their fixation mainly relies on the elastic deformation of the spring. During violent coughing, rebound or fatigue may occur, leading to loosening of the fixation. Furthermore, the spring fixation lacks active adjustment capability, and when the spring experiences metal fatigue, uneven force can easily cause the cannulas to deviate. Therefore, the aforementioned devices are prone to causing secondary injury to patients during use. In view of this, an adjustable airway tracheostomy fixation device is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an adjustable tracheostomy fixation device that can overcome or at least partially solve the above problems.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] An adjustable tracheostomy fixation device includes a housing and further includes: a drive disc rotatably installed inside the housing; multiple sets of fixing blocks arranged around the drive disc; a soft pad detachably connected to the housing, wherein the soft pad, drive disc, and housing are all provided with perforations, and the three sets of perforations are coaxial; a connecting frame is provided on the housing, and a strap is attached to the connecting frame.

[0008] As a preferred embodiment of the present invention: the outer shell includes a first shell and a second shell, the first shell is provided with an integrally formed limiting ring, and the second shell is provided with an integrally formed limiting strip.

[0009] In a preferred embodiment of the present invention, the connecting frame includes a first mounting frame fixedly mounted on the first housing and a second mounting frame fixedly mounted on the second housing, wherein the first mounting frame and the second mounting frame are fixed together by bolts.

[0011] In a preferred embodiment of this utility model, the fixing block includes a sliding block that is attached to the worm gear disk, and the two sides of the sliding block are in contact with the limiting strip.

[0012] As a preferred embodiment of the present invention: buffer blocks are fixedly installed on each of the multiple sets of sliding blocks, and the end of the buffer block facing the through hole axis is set to be arc-shaped.

[0013] In a preferred embodiment of this utility model, the soft pad is fixed to the outer shell by Velcro, and the soft pad is provided with a first vent hole and a second vent hole, the axes of the first vent hole and the second vent hole being perpendicular to each other.

[0014] In a preferred embodiment of this utility model, the soft pad is one of sponge, silicone, or rubber.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0027] Example: Refer to Figures 1-6An adjustable tracheostomy fixation device includes a housing 1, and further includes: a drive disc 2 rotatably installed inside the housing 1; multiple sets of fixing blocks 3 arranged around the drive disc 2; a soft pad 6 detachably connected to the housing 1 (the soft pad 6 is made of one of three materials: sponge, silicone, and rubber), the soft pad 6, the drive disc 2, and the housing 1 are all provided with perforations, and the three sets of perforations are coaxial; a connecting frame 4 is provided on the housing 1, and a strap 5 (preferably Velcro) is tied to the connecting frame 4.

[0028] When in use, the outer shell 1 is fixed to the human body by the strap 5. At this time, the soft pad 6 is in contact with the human body. Then, the drive plate 2 is rotated to make multiple sets of fixing blocks 3 move synchronously to the outer ring of the drive plate 2. Then, the tracheostomy tube passes through the perforation and multiple sets of fixing blocks 3 to connect the tracheostomy tube with the human trachea. Then, the drive plate 2 is rotated in the opposite direction to make multiple sets of fixing blocks 3 move synchronously to the perforation, thereby clamping and fixing the tracheostomy tube.

[0029] Reference Figure 4 and Figure 7 The outer shell 1 includes a first shell 11 and a second shell 12. The first shell 11 is provided with an integrally formed limiting ring 14, and the second shell 12 is provided with an integrally formed limiting strip 13. The connecting frame 4 includes a first mounting frame 41 fixedly installed on the first shell 11 and a second mounting frame 42 fixedly installed on the second shell 12. The first mounting frame 41 and the second mounting frame 42 are fixed by bolts 43. The first shell 11 and the second shell 12 can be opened, so as to facilitate the replacement of the fixing block 3 and the drive disk 2.

[0030] Reference Figures 2-7 The drive disk 2 includes a worm gear disk 21, which has a limiting groove that fits with the limiting ring 14. The side wall of the worm gear disk 21 has a drive protrusion 22 for moving the worm gear disk 21. The fixing block 3 includes a sliding block 31 that fits with the worm gear disk 21. The two sides of the sliding block 31 fit with the limiting strip 13.

[0031] By placing a finger against the drive protrusion 22, the worm gear disk 21 is rotated, which in turn drives the sliding block 31 to move along the limiting strip 13. The limiting ring 14 and the limiting strip 13 respectively limit the worm gear disk 21 and the sliding block 31, thereby preventing the worm gear disk 21 and the sliding block 31 from shifting during movement.

[0032] Reference Figure 3 Each set of sliding blocks 31 is fixedly equipped with a buffer block 32 (rubber or silicone). The end of the buffer block 32 facing the perforation axis is set to be arc-shaped. When the arc-shaped end face of the buffer block 32 contacts the tracheostomy tube, it can disperse pressure, reduce local friction, and avoid scratching the surface of the tube.

[0033] Reference Figure 6The soft pad 6 is fixed to the outer shell 1 by Velcro. The soft pad 6 can be replaced as needed. The soft pad 6 is provided with a first ventilation hole 61 and a second ventilation hole 62. The axes of the first ventilation hole 61 and the second ventilation hole 62 are perpendicular to each other. The perpendicular design of the axes of the first ventilation hole 61 and the second ventilation hole 62 can form a cross airflow channel, which enhances the air circulation in the area where the soft pad 6 contacts the skin, reduces local moisture and sweat accumulation, and reduces the risk of skin maceration and pressure sores.

[0034] In summary, this device has the following advantages:

[0035] The mechanical structure adopts a worm gear disk 21 to drive multiple sets of sliding blocks 31 to move synchronously. The rotation of the drive disk 2 achieves uniform force application, avoiding the problems of fatigue and uneven force distribution of traditional spring fixing. The clamping force is evenly distributed, effectively preventing the sleeve from deflecting or slipping.

[0036] The limiting ring 14 and the limiting strip 13 respectively constrain the movement trajectory of the worm gear disk 21 and the sliding block 31, ensuring no deviation during clamping and improving fixation stability (especially suitable for dynamic scenarios when coughing or changing body position).

[0037] The arc-shaped buffer block 32 (made of silicone / rubber) at the end of the sliding block 31 can disperse the pressure on the tracheostomy tube. The arc-shaped surface is adapted to different tube diameters to avoid hard contact that could damage the surface of the tracheostomy tube.

[0038] The bidirectional vertical ventilation design creates cross airflow channels, significantly improving skin breathability, reducing sweat buildup and bacterial growth. The Velcro-fixed pads can be quickly replaced for easy cleaning or to suit different patient needs.

[0039] The first housing 11 and the second housing 12 are connected by bolts 43, which allows for quick disassembly and replacement of internal components (such as the fixing block 3 and the drive disk 2), extending the service life of the device and reducing maintenance costs.

[0040] The drive bump 22 makes it easy for medical staff to operate while wearing gloves, and can complete the fixation or release of the cannula without tools, making it suitable for rapid handling in emergency situations.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model.
