Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a medical ventilator tubing support device. Background Technology

[0002] A ventilator is a crucial medical device used to prevent and treat respiratory failure, reduce complications, and save and prolong patients' lives. During use, the medical ventilator tubing has a certain weight; if it presses directly on the patient, it can easily cause pressure sores and discomfort.

[0003] To reduce the pressure of medical ventilator tubing on patients, in existing technologies, medical staff typically inflate medical rubber gloves with their mouths, causing the gloves to expand into an air bladder, which acts as a support device for the medical ventilator tubing. The ventilator tubing is then placed on top of the inflated glove to provide support and cushioning, thereby reducing the occurrence of pressure sores.

[0004] However, the existing medical ventilator tubing support structure has an uncontrollable shape of inflatable gloves and a limited expansion height, making it impossible to adjust the distance between the medical ventilator tubing and the patient's skin as needed. This results in the medical ventilator tubing coming into contact with the patient's skin, thus causing pressure sores.

[0005] Therefore, existing technologies have defects and shortcomings, and need further improvement and development. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of this application is to provide a medical ventilator tubing support device, which aims to solve the problem that the existing medical ventilator tubing support devices cannot adjust the distance between the medical ventilator tubing and the patient's skin as needed.

[0039] Please refer to the following: Figures 1 to 6 , Figures 1 to 6The medical ventilator tubing support device 10 shown is in an inflated state. This application provides a medical ventilator tubing support device 10 for supporting medical ventilator tubing. The medical ventilator tubing support device 10 includes a support layer 13, a height adjustment layer 11, and a bottom balloon 12. The support layer 13 is disposed above the height adjustment layer 11, and the bottom balloon 12 is disposed below the height adjustment layer 11. The three layers are stacked to form a stable support structure. A retractable air tube 111 is disposed inside the height adjustment layer 11. Figure 5 As shown, the retractable air tube 111 has several air holes 1111, which are respectively connected to the inflation / deflation cavities 1121 of multiple inflation adjustment rings 112. The inflation adjustment rings 112 are sequentially arranged around the retractable air tube 111, and the retractable air tube 111 is embedded in the multiple inflation adjustment rings 112. The inflation adjustment rings 112 are used to realize the height adjustment function. Each inflation adjustment ring 112 is composed of a first frustum layer 1122, a telescopic ring 1123, and a second frustum layer 1124 from top to bottom. A weight-reducing gap 1125 is provided between the first frustum layer 1122 and the second frustum layer 1124 to reduce the overall weight of the device. The bottom balloon 12 is the support structure located at the bottom of the device, which is used to contact the patient's body and provide basic support and cushioning. The support layer 13 is used to fix the ventilator tubing. The support layer 13 is provided with a cross sliding groove 1321 and a fixing member 1333. The fixing member 1333 is used to clamp the ventilator tubing. The cross sliding groove 1321 allows medical staff to adjust the position of the fixing member 1333 according to clinical needs, so as to match different lengths, positions and directions of the ventilator tubing.

[0040] like Figure 6 As shown, during operation, the medical ventilator tubing is first connected to the fixing component 1333. Medical personnel inflate the retractable tubing 111 through the externally connected inflation / deflation component 14. Specifically, the inflation / deflation component 14 can be an inflatable balloon, an air pump, or an electric air pump. Gas enters the inflation / deflation cavity 1121 of the inflation adjustment ring 112 sequentially through the air holes 1111, causing each inflation adjustment ring 112 to expand sequentially. The expanded retractable ring 1123 connects the upper and lower frustum layers, forming a layered structure with supporting rigidity. This gradually increases the overall height of the height adjustment layer 11 and pushes the support layer 13 upward. Because the air holes 1111 are arranged in an upper-lower order and the diameter can gradually increase, the gas inflation speed and pressure can be controlled layer by layer, forming a balanced inflation effect from bottom to top and avoiding uneven local expansion.

[0041] When medical staff determine that the medical ventilator tubing support device 10 has separated the ventilator tubing or the humidifier tank on the ventilator tubing from the patient's skin, inflation is stopped. If over-inflation occurs, gas can be released through the deflation port of the inflation / deflation device 14. The bottom balloon 12 provides flexible support throughout the inflation process. When uneven bed surfaces or different patient body shapes cause support gaps, the bottom balloon 12 can automatically conform to its shape, ensuring a stable fit and enhancing support reliability and patient comfort. Finally, the ventilator tubing is held in place by the fasteners 1333 on the support layer 13, transferring the weight of the tubing to the entire support structure. This achieves stable support and adjustment of the ventilator tubing, preventing direct pressure on the patient's body and the formation of pressure sores.

[0042] Please refer to the following: Figures 1 to 2In some embodiments, the medical ventilator tubing support device 10 includes a height adjustment layer 11, a bottom balloon 12, a support layer 13, and an inflation / deflation component 14. The height adjustment layer 11 is used to achieve height adjustment through gas inflation. The bottom balloon 12 is fixedly connected to the lower end of the height adjustment layer 11. The support layer 13 is fixedly connected to the upper end of the height adjustment layer 11. The upper part of the support layer 13 is provided with an inflation nozzle 131 for inflating the height adjustment layer 11 and a fastening connector 133 for connecting the medical ventilator tubing. The inflation / deflation component 14 is detachably connected to the inflation nozzle 131. The inflation / deflation component 14 is used to inflate or deflate the height adjustment layer 11. The height adjustment layer 11 is provided with a retractable gas... The system comprises a tube 111 and several inflation adjustment rings 112. The retractable air tube 111 is embedded in several inflation adjustment rings 112, and the retractable air tube 111 is used to connect several inflation adjustment rings 112 and inflation nozzles 131. Specifically, the outer wall of the retractable air tube 111 is tightly fitted with the inner wall of each inflation adjustment ring 112 to form an airtight connection, ensuring that gas can be transferred layer by layer to the inflation / deflation cavities 1121 of each inflation adjustment ring 112. The retractable air tube 111 is embedded in several inflation adjustment rings 112 and passes through multiple inflation adjustment rings 112, and is longitudinally arranged in the height adjustment layer 11, forming a gas inflation / deflation channel. The height adjustment layer 11 is used to expand after inflation and adjust the distance between the support layer 13 and the bottom balloon 12. Furthermore, by setting up a height adjustment layer 11, a bottom balloon 12, and a support layer 13, and integrating a retractable trachea 111 and several inflation adjustment rings 112 in the height adjustment layer 11, the medical ventilator tubing support device 10 can be flexibly adjusted according to the patient's body shape, positional changes, or clinical operation needs; the inflation volume is adjusted by the inflation / deflation component 14 to achieve height controllability, solving the problem of non-adjustable support device height in the prior art. The medical ventilator tubing support device 10 can maintain the distance between the medical tubing and the patient's body, avoiding pressure sores caused by single-point contact of the tubing weight with the skin surface, thus improving patient comfort and safety.

[0043] Please refer to the following: Figures 4 to 6In some embodiments, the retractable air tube 111 is provided with a plurality of air holes 1111, which are correspondingly arranged with the inflation / deflation cavities 1121 in the inflation / deflation adjustment rings 112. The air holes 1111 are used to connect the inflation / deflation cavities 1121 with the gas inflation / deflation channel. Furthermore, by providing multiple air holes 1111 on the retractable air tube 111 and connecting each air hole 1111 to the inflation / deflation cavities 1121 of the multiple inflation / deflation adjustment rings 112, a multi-node gas supply structure is formed. During inflation, multi-point gas distribution can be achieved, thus ensuring that each adjustment ring is evenly pressurized. This further avoids problems such as local bulging or unstable support caused by gas concentration in one place. The height adjustment layer 11 also has a certain strength even when not inflated, ensuring that the entire medical ventilator tubing support device 10 has a regular shape and good load-bearing capacity after inflation.

[0044] Please refer to the following: Figures 4 to 6 In some embodiments, the diameter of the plurality of air holes 1111 gradually increases from the support layer 13 to the bottom balloon 12. By designing the diameter of the air holes 1111 to gradually increase from the support layer 13 to the bottom balloon 12, the inflation flow rate can be gradually increased from bottom to top during use, allowing the inflation adjustment ring 112 to inflate sequentially from bottom to top. This helps to control the inflation sequence and speed, preventing gas from rushing into the upper part and causing the bottom of the device to collapse or become unstable, thus enhancing the stability and safety of the device during adjustment and improving the user adjustment experience.

[0045] Please refer to the following: Figure 2In some embodiments, each of the inflatable adjusting rings 112 includes a first frustum layer 1122, a telescopic ring 1123, and a second frustum layer 1124 arranged sequentially from top to bottom. The telescopic ring 1123 is used to constrain the first frustum layer 1122 and the second frustum layer 1124. Specifically, each inflatable adjusting ring 112 is an integral hollow ring structure, with the first frustum layer 1122 and the second frustum layer 1124 located at the upper and lower ends, respectively, and connected by the telescopic ring 1123. The telescopic ring 1123 can expand radially or axially in the inflated state, restricting the relative displacement between the first frustum layer 1122 and the second frustum layer 1124, so that the inflatable adjusting ring 112 as a whole has an elastic adjustment function. The inflatable adjusting ring 112 adopts a three-segment combination structure of "first frustum layer 1122 - telescopic ring 1123 - second frustum layer 1124", forming a gradually changing support configuration during inflation. The first frustum layer 1122 and the second frustum layer 1124 have good deformation adaptability and stability. Together with the telescopic ring 1123 structure set in the middle of the inflation adjustment ring 112, they can actively constrain the expansion range of the adjustment ring, thereby effectively avoiding the problem of excessive expansion or uncontrolled deformation, making the overall height adjustment process more controllable, and ensuring the structural stability of the support device during long-term use.

[0046] Please refer to the following: Figure 2 In some embodiments, a weight-reduction gap 1125 is provided between the first frustum layer 1122 and the second frustum layer 1124. This weight-reduction gap 1125 is used to reduce the weight of the inflation adjustment ring 112. Providing a weight-reduction gap 1125 between the first frustum layer 1122 and the second frustum layer 1124 reduces the amount of unnecessary materials used without affecting the overall structural strength and morphological stability, thereby reducing the overall weight of the device. This reduces material costs and alleviates pressure on the patient's skin, contributing to improved comfort and safety during prolonged use.

[0047] Please refer to the following: Figure 2 In some embodiments, the support layer 13 is provided with a support body 132 and a fastening connector 133; one end of the support body 132 is fixedly connected to the other end of the height adjustment layer 11; the fastening connector 133 is disposed on the other end of the support body 132, and the fastening connector 133 is slidably connected to the support body 132, and the fastening connector 133 is used to support the medical ventilator tubing. This enables adjustment of the horizontal position of the ventilator tubing. In actual use, different patient positions, bed postures, or ventilator wiring methods vary. The sliding adjustment structure allows for quick adjustment of the position of the fastening connector 133 on the support layer 13 according to the actual situation, thereby optimizing the medical tubing guidance path, avoiding the risks of blockage or detachment caused by tubing being suspended or bent, and improving the versatility of the device.

[0048] Please refer to the following: Figures 2 to 4 In some embodiments, a cross-shaped sliding groove 1321 is provided at the other end of the support body 132, which is used for the sliding of the fastening connector 133. Furthermore, through the cross-shaped sliding groove 1321 provided in the support body 132, the fastening connector 133 can be adjusted in two dimensions: the front-back horizontal direction and the left-right horizontal direction, further enhancing the adjustment freedom of the ventilator tubing support device.

[0049] Please refer to the following: Figure 2 In some embodiments, the fastening connector 133 includes a support arm body 1331, a cross sliding base 1332, and a fixing member 1333. The cross sliding base 1332 is fixedly disposed at one end of the support arm body 1331. The cross sliding base 1332 is used for sliding connection with the cross sliding groove 1321. Specifically, the cross sliding base 1332 is embedded in the cross sliding groove 1321 and slides along the horizontal and vertical directions of the cross groove. A limit structure is provided between the sliding base and the sliding groove to prevent the fastening connector 133 from falling off. The fixing member 1333 is disposed at the other end of the support arm body 1331 and is used to fix the medical ventilator tubing. The fastening connector 133, composed of the support arm body 1331, the cross sliding base 1332, and the fixing member 1333, adopts a modular design and can rotate relative to each other, which not only facilitates assembly, disassembly, and transportation but also facilitates expansion or replacement in the future according to different usage scenarios. The cross-shaped sliding base 1332 is embedded in the cross-shaped sliding groove 1321, which can stably achieve the positioning of the fastening connector 133, while the fixing part 1333 is used to firmly connect the ventilator tubing, further improving the overall stability and load-bearing capacity of the support device.

[0050] Please refer to the following: Figure 2In some embodiments, the fastener 1333 is configured as a U-shaped groove, with Velcro loops 1334 and Velcro hooks 1335 respectively provided on both sides of the top end. Specifically, the U-shaped groove is used to accommodate medical ventilator tubing. After the tubing is inserted, the Velcro loops 1334 and Velcro hooks 1335 on both sides of the top end fit together to secure it. The Velcro has a certain length adjustment margin, suitable for tubing of different diameters. Using a U-shaped groove structure as the fastener 1333 can firmly hold cylindrical or near-circular medical ventilator tubing, and the Velcro loops 1334 and Velcro hooks 1335 enable quick installation and removal. This provides advantages such as convenient operation, strong compatibility, and high reusability, allowing for rapid adaptation to various ventilator tubing specifications, improving overall operational efficiency and safety, and reducing the workload of medical personnel.

This provides users with multiple inflation options, improving the device's adaptability and ease of use. Especially in clinical use, appropriate inflation / deflation tools can be selected based on actual needs such as availability of power and required inflation speed, enhancing the versatility and reliability of the medical ventilator tubing support device 10 in various environments, including bedside use, emergency scenarios, and home healthcare.

[0052] Please refer to the following: Figure 6 In some embodiments, after the air outlet tube of the inflatable balloon is inserted into the air inlet 131, rotating the adjustment knob of the inflatable balloon clockwise inflates the height adjustment layer 11, and rotating the adjustment knob of the inflatable balloon counterclockwise deflates the height adjustment layer 11.

[0053] Please refer to the following: Figure 2 In some embodiments, the bottom balloon 12 is not connected to the height adjustment layer 11, the bottom balloon 12 is configured as a hollow hemispherical structure, and the bottom balloon 12 has an independent air chamber inside, which can be inflated separately by an external inflation / deflation device 14.

[0054] In some implementations, medical personnel may use physical disinfection, chemical disinfection, biological disinfection, radiation disinfection, or a combination of disinfection methods to disinfect the medical ventilator tubing support device 10.

[0055] In some embodiments, the retractable air tube 111 may be arranged in an S-shape around the height adjustment layer 11.

[0056] In some embodiments, the support layer 13, the height adjustment layer 11, and the bottom balloon 12 can be flexibly selected from lightweight materials with good biocompatibility and a certain degree of elasticity, such as natural latex, polycaprolactone plastic, polylactic acid plastic, or polyhydroxyalkanoate plastic, which can greatly reduce the weight of the medical ventilator tubing support device 10 and improve the biocompatibility of the medical ventilator tubing support device 10.
