Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a tracheotomy strap for preventing pressure injuries. Background Art

[0002] At present, when tracheostomy patients install tracheostomy tubes, they are mostly tied around the neck with a lace. Since most of the laces are relatively thin and tied tightly, the skin in contact with the laces is prone to pressure sores or even damage over time, which not only makes people feel uncomfortable, but also easily causes infection, which is not conducive to the patient's recovery. Therefore, it is necessary to design a tracheostomy tube fixing device that can avoid the occurrence of pressure sores, among which a tracheostomy tube lace with application number "CN201520923192.3" includes a main body, which is in the shape of a belt, connected to the tracheostomy tube in the middle, and provided with a plurality of soft pads on both sides to prevent skin compression. The utility model has a reasonable design, a simple structure, and is easy to use. It can effectively avoid the problem of pressure sores or damage to the skin when fixing the tracheostomy tube, improve the patient's comfort, and enhance the quality of medical care. However, the laces still have certain deficiencies in use: since the pads provided on the surface of the main body only have the effect of preventing pressure sores on the skin contact parts, other parts of the main body will still cause pressure injuries to the skin contact parts, and the diameters of tracheostomy tubes are different, the laces cannot fix tracheostomy tubes of different diameters. Utility Model Content

[0003] The utility model aims to provide a tracheostomy strap for preventing pressure injuries, so as to solve the problem raised in the above-mentioned background technology that the pads provided on the surface of the body only have the effect of preventing pressure sores on the skin contact part, so that other parts of the body will still cause pressure injuries to the skin contact part, and the diameters of tracheostomy tubes are different, and the strap cannot fix tracheostomy tubes of different diameters.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tracheotomy strap for preventing pressure injuries, comprising a fixing block, an inflation component and a clamping component;

[0005] Wherein: the two sides of the fixing block are connected with connecting buckles, the interiors of the connecting buckles on both sides are connected with strip air bags, an exhaust valve is installed on one end of the surface of the strip air bag, and the surface of the fixing block is connected with a mounting block;

[0006] The inflation assembly includes an air inlet pipe connected to the top of the strip airbags on both sides, a three-way valve is installed on the top of the mounting block, one end of the two air inlet pipes is connected to the three-way valve, the top of the three-way valve is connected to an inflation pipe, and one end of the inflation pipe is connected to the inflation balloon;

[0007] The clamping assembly includes mounting cavities on both sides of the mounting block, through holes are formed in the middle of the fixing block and the mounting block, a mounting hole is formed inside the mounting cavity, the mounting hole is connected to the through hole in the middle of the mounting block, a sliding rod is slidably installed inside the mounting hole, one end of the sliding rod is inserted into the through hole and is connected to a clamping ring, and an adjustment handle is installed on the surface of the sliding rod.

[0008] As a preferred solution of the utility model: travel grooves communicating with the installation cavity are provided on both sides of the surface of the installation block, and the adjustment handle is slidably inserted into the travel grooves.

[0009] As a preferred solution of the utility model: a retaining ring is installed in the middle of the slide rod, a spring is installed inside the installation cavity, and the spring is sleeved on the surface of the slide rod and is in contact with the retaining ring.

[0012] As a preferred solution of the utility model: the inner wall of the strip-shaped airbag is connected with a breathable foam pad.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) Strip airbags are connected to both sides of the fixing block, and the strip airbags replace the ordinary lacing structure. When the strip airbag is fixed at the neck position, the inflated airbag is manually squeezed to allow external gas to be filled into the strip airbag through the air inlet pipe. After the strip airbag is inflated, it begins to expand, making it fit tightly to the neck. When the patient feels that the pressure of the strip airbag is high, the air in the strip airbag is discharged to the outside through the exhaust valve, so that the tightness of the strip airbag fixation can be adapted to the patient. The breathable foam pad connected to the inner wall of the strip airbag can allow the neck to be ventilated. The coordinated use of the strip airbag and the breathable foam pad can effectively prevent pressure injuries on the patient's neck and neck.

[0015] (2) Through the provided clamping assembly, the opening and closing size of the clamping ring is adjusted according to the diameter of the tracheostomy tube. The adjustment handle is manually turned to move inside the travel groove. The movement of the adjustment handle drives the slide bar to move inside the mounting hole, so that the slide bar drives the two clamping rings to move away from each other. When the tracheostomy tube is placed in the middle of the two clamping rings, the adjustment handle is released, and the spring reset pushes the slide bar to reset. At this time, the slide bar drives the clamping ring to clamp and fix the tracheostomy tube, thereby realizing the installation and fixation of tracheostomy tubes of different sizes, thereby improving the scope of application.

The two strip air bags 3 are inflated with gas through the air inlet pipes 51 and expanded. After the strip air bags 3 are expanded, they fit the patient's neck, so that the fixing block 1 is fixed at the patient's throat position. When the pressure of the patient's strip air bags 3 is high, the air in the strip air bags 3 is discharged outwardly through the exhaust valve 31, so that the tightness of the strip air bags 3 can be adapted to the patient. The adjustment knob 55 on the surface of the three-way valve 52 can control different air intake amounts between the two strip air bags 3, so as to adjust the expansion of one side of the strip air bags 3 according to the deviation of the patient's neck.
