Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical assistive device technology, and in particular to a pressure injury prevention device for high-flow oxygen delivery tubes. Background Technology
[0002] In the medical field, high-flow oxygen therapy and high-flow respiratory support are widely used treatments. However, during the use of high-flow tubing, due to its large diameter, heavy weight, and prolonged contact with the patient's skin, the patient's nose, face, ears, and other areas are frequently subjected to pressure from the tubing, resulting in a high incidence of pressure injuries.
[0003] Existing measures to prevent pressure injuries have many shortcomings. Some simple protective pads, such as ordinary sponge pads or silicone pads, like napkins or gauze placed on the patient's nose, face, or ears, are prone to falling off due to changes in the patient's position, also affecting aesthetics. They cannot be flexibly adjusted according to the patient's body contours and the direction of the tubing, cannot effectively distribute pressure, and have poor pressure-prevention effects. Some fixation devices, when fixing tubing, can easily create new pressure points on the patient's skin, not only failing to solve the pressure injury problem but potentially aggravating skin damage. Utility Model Content
[0004] This invention provides a pressure-resistant device for high-flow oxygen delivery tubing to address the problem in existing technologies where fixing the tubing can easily create new pressure points on the patient's skin, which not only fails to solve the pressure injury problem but may also worsen skin damage.
[0005] The technical problem solved by this utility model is achieved by the following technical solution:

[0043] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0044] Reference Figure 1-5 The high-flow oxygen supply line anti-pressure injury device shown includes:
[0045] There are two fitting pads 100. They are made of soft, breathable and elastic silicone material. The shape is designed according to the contour of the nose, face and ears. They can fit closely to the patient's nose, face and ears. The two fitting pads 100 are connected by a receiving pipe 200. The receiving pipe 200 has good flexibility and will not significantly hinder the patient's head movement while connecting the two fitting pads.
[0046] The mounting groove 300 is formed on the fitting pad 100 to accommodate the components to be installed later;
[0047] Two sets of elastic airbags 400 are provided and are respectively bonded inside the two mounting grooves 300. The elastic airbags are interconnected. The elastic airbags 400 are made of soft and highly elastic silicone material. This silicone has excellent flexibility, which can not only effectively buffer external pressure, but also sensitively sense and adapt to the subtle differences in the facial contours of different patients, providing a personalized and comfortable fit.
[0048] The intake and exhaust pipe 500 is installed on one of the elastic air bags 400 and connected to an external small air pump to ensure that the gas can flow into the elastic air bag 400 efficiently and evenly, providing a stable gas source for subsequent oxygen supply operations.
[0049] The airflow regulating device 600 is installed on the inlet and outlet pipes 500 to regulate the exhaust and inlet speeds of the elastic airbag 400. It effectively controls the gas flow rate into the elastic airbag 400 and the gas speed out of the airbag in all directions, ensuring that the air pressure inside the elastic airbag 400 is always maintained within a suitable range to meet the strict requirements for gas flow rate and pressure in different usage scenarios.
[0050] The fixation strap 700 has two parts. The fitting pad 100 is worn on the patient's face. The fixation strap 700 is made of elastic non-woven fabric and its length can be adjusted by Velcro, so as to easily fix the fitting pad to the patient's head and minimize friction and pressure on the skin.
[0051] The working principle of this embodiment is as follows:
[0052] The high-flow oxygen delivery line is passed through the fitting pad 100, and then the fitting pad 100 is worn on the patient's face by the fixing strap 700. Then the inlet and outlet pipe 500 is connected to the small air pump and the small air pump is started. The small air pump will inflate the elastic air bag 400 with gas through the inlet and outlet pipe 500, causing the elastic air bag 400 to expand.
[0053] The 700 fixing strap can be adjusted in length via Velcro or buckles, making it simple and convenient to operate. This allows medical staff to easily put on and adjust the device for patients, ensuring good compatibility between the device and the patient's body and tubing, and guaranteeing the effectiveness of the device.
[0054] The elastic airbag 400 can automatically adjust the pressure according to the weight and shape of the tubing, evenly distributing the pressure of the tubing on the skin, greatly reducing the risk of pressure injury. For patients with sensitive skin, the pressure of the elastic airbag can be appropriately reduced to more gently distribute the pressure of the tubing; for heavier tubing, the pressure of the elastic airbag can be increased to better support the tubing.
[0055] The airflow regulating device 600 allows for adjustment of the air intake and exhaust speeds of the elastic airbag 400, making it easier to control changes in the internal air pressure of the elastic airbag 400.
[0056] In some embodiments of this utility model, reference is made to Figure 2 As shown, the lower surface of the pad 100 is bonded with a breathable and sweat-absorbing layer 110 that comes into contact with the patient's face. On the side of the pad that comes into contact with the skin, there is a breathable and sweat-absorbing layer made of skin-friendly cotton material. The middle of the pad 100 has a channel 120 for a high-flow oxygen delivery line to pass through.
[0057] Among them, the breathable and sweat-absorbing layer 110 can absorb sweat from the skin surface in time during the period when the patient wears the device, keep the skin dry, and reduce discomfort and damage caused by sweat irritating the skin.
[0058] The fitting pad 100 is made of soft, breathable and elastic material, and a breathable and sweat-absorbing layer 110 is set up so that it can fit the skin and keep the skin dry, improving the comfort of patients wearing it for a long time.
[0059] The shape of the fitting pad 100 is designed according to the common pressure points of the human body, and the channel 120 can accommodate high-flow pipelines of different diameters.
[0060] In some embodiments of this utility model, reference is made to Figure 3 and Figure 5 As shown, an air guide pipe 210 is fixedly installed inside the receiving pipe 200, and both ends of the air guide pipe 210 are connected to two sets of elastic airbags 400 respectively, to ensure that the gas can flow evenly between the two sets of elastic airbags and maintain the consistency of pressure.
[0061] In some embodiments of this utility model, reference is made to Figure 3 and Figure 4 As shown, the airflow regulating device 600 includes:
[0062] Casing 610;
[0063] There are two sealing plates 620, which are installed inside the housing 610 and can rotate relative to each other, with the two sealing plates 620 in sealing contact with each other;
[0064] The sealing gasket 630 is bonded to the side of the sealing plate 620 that is close to it. The sealing gasket 630 is made of a soft material with good sealing performance. It can fit tightly when the sealing plate 620 is rotated and closed, effectively preventing gas leakage and ensuring stable gas pressure inside the device.
[0065] Two sets of airflow holes 640 are provided, which are respectively opened on two sealing plates 620. When the two sealing plates 620 rotate relative to each other, the overlapping range of the airflow holes 640 is adjusted. As the two sealing plates 620 rotate relative to each other, the overlapping range of the airflow holes 640 changes, thereby changing the cross-sectional area of the gas flow and realizing the regulation of the airflow speed.
[0066] The intake and exhaust speeds of the intake and exhaust pipes 500 are adjusted by varying the overlap size of the air passages 640, so as to facilitate precise control of the internal air pressure of the elastic airbag 400.
[0067] In some embodiments of this utility model, reference is made to Figure 3 and Figure 4 As shown, the housing 610 includes:
[0068] The housing 611 is connected to the inlet and outlet pipes 500 and is fixed to the outer side of one of the sealing plates 620;
[0069] The rotating housing 612 is connected to the inlet and outlet pipes 500 and the outer side of another sealing plate 620 is fixed. It can also rotate relative to the fixed housing 611 to meet different working requirements.
[0070] The sealing sleeve 613 is fitted onto the connection between the fixed housing 611 and the rotating housing 612. The sealing sleeve 613 is made of high-quality sealing material, which can effectively prevent gas from leaking from the connection and ensure the airtightness and stability of the entire device.
[0071] The working principle of this embodiment is as follows:
[0072] Rotating the housing 612 will cause one of the sealing plates 620 to rotate, which will change the position of the corresponding air passage 640 and change the size of the overlapping area with the air passage 640 on the other sealing plate 620.
[0073] In some embodiments of this utility model, reference is made to Figure 3 and Figure 4 As shown, the outer side of the sealing sleeve 613 is provided with a numerical scale 614, and the outer side of the rotating housing 612 is provided with a pointer 615 pointing to the numerical scale 614.
[0074] Medical staff can precisely adjust the overlap range of the air passage 640 by rotating the housing 612, which in turn causes the sealing plate 620 to rotate relative to it. At the same time, they can observe the pointer and numerical scale to achieve precise control over the air release and intake speed of the elastic airbag.
[0075] In some embodiments of this utility model, reference is made to Figure 2 As shown, both ends of the channel 120 are fitted with positioning rings 130 that are fixed to the outside of the high-flow oxygen supply line. Positioning rings 130 with different central diameters are selected according to the diameter of the high-flow oxygen supply line.
[0076] The positioning ring 130 ensures the stable position of the high-flow oxygen delivery line within the channel 120, preventing the line from shifting due to patient movement or other factors. It also prevents the line from being subjected to hard compression, which would affect gas delivery. While ensuring the stability of the line, it also fully maintains the smoothness of gas delivery.
[0077] The working method of this utility model:
[0078] Based on the size of the patient's head, adjust the length of the fixing strap 700 using Velcro, attach the fitting pad 100 to both sides of the patient's face, ensuring that the high-flow oxygen delivery line is located within the channel 120 and in the correct position. Then, wrap the fixing strap 700 around the patient's head and secure it with Velcro to ensure the device is worn stably. Turn on the air pump, and the gas enters the elastic air bag 400 through the inlet and outlet pipes 500, causing the elastic air bag to inflate and fit against the patient's face.
[0079] Medical staff observe the patient's reaction. If the patient feels uncomfortable due to pressure, and it is necessary to slightly change the internal air pressure setting of the elastic airbag 400, the overlapping range of the air passage 640 can be precisely adjusted by rotating the rotating housing 612 according to the numerical scale 614 on the sealing sleeve 613 and the pointer 615 on the rotating housing 612. This adjusts the exhaust and intake speed of the elastic airbag 400, changes the pressure inside the elastic airbag, until the patient feels comfortable.
[0080] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
