Inflatable toe ring

Abstract

This utility model provides an inflatable foot ring, including a foot ring with an air chamber. An air tube is provided on the outer wall of the foot ring, capable of inflating and deflating the air chamber. A plug is detachably installed at the end of the air tube away from the air chamber, capable of sealing the air tube. A groove is formed around the outer periphery of the plug. A groove corresponding to the groove is formed around the inner periphery of the air tube, and a rubber layer completely covering the groove opening is provided. Two opposing plug grooves are radially formed on the outer periphery of the air tube, with their concentric ends connecting to the two sides of the groove. A piston is installed in the plug groove. By driving the piston to move from the plug groove towards the groove, the pressure medium in the groove is compressed, forcing the rubber layer to expand and deform, sealing and locking into the groove. Simply driving the piston to move relative to the plug groove automatically performs a secondary sealing and fixation of the air tube with the plug inserted, preventing air leakage from the foot ring when the plug falls off due to damage, fatigue, or incomplete sealing of the air tube.

Description

Technical Field

[0001] This utility model relates to the field of inflatable protective gear technology, specifically to inflatable foot rings. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] For comatose, bedridden, and paralyzed patients, the skin on their heels when lying supine and the skin on their ankles when lying on their sides are prone to pressure sores due to prolonged pressure, causing significant pain and greatly increasing the difficulty of nursing care. Foot bands are typically placed around the patient's heels or ankles to suspend them in the air, preventing pressure on the skin and reducing the risk of pressure sores, thus alleviating the patient's suffering.

[0004] Traditional inflatable foot rings use a plug to seal the inflation tube after inflation. However, when the plug is damaged, fatigued, or not completely sealed at the inflation tube opening, the foot ring leaks air and cannot meet the normal use requirements of patients. Utility Model Content

[0005] The main purpose of this invention is to provide an inflatable foot ring.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: an inflatable foot ring, characterized in that it includes a foot ring with an air cavity, an air tube that can inflate and deflate the air cavity is provided on the outer wall of the foot ring, and a tube plug that can be plugged into and out of the air tube is provided at the end of the air tube away from the air cavity; a groove is formed on the outer periphery of the tube plug.

[0007] A groove corresponding to the position of the slot is formed around the inner circumference of the trachea. A rubber layer is provided at the opening of the groove to completely cover the opening of the groove, and a pressurized area is formed between the groove and the rubber layer.

[0008] Two opposing plug grooves are radially formed on the outer peripheral sidewall of the trachea, with the centripetal ends of the two plug grooves respectively connecting to the two sides of the groove; a piston is installed in the plug groove, and both the pressurization area and the plug groove contain a pressure medium;

[0009] By driving the piston to move from the groove to the recess, the pressure medium in the recess is squeezed, forcing the rubber layer to expand and deform to seal and snap into the groove.

[0010] Furthermore, each of the two plug grooves is fixed with a fixed plate, and a plug rod parallel to the extension direction of the plug groove body is slidably inserted into each fixed plate, with the centripetal end of the plug rod fixed to the outer wall of the corresponding piston.

[0011] Furthermore, a fixed ring is fitted and fixed to the outside of the trachea. Two opposing insertion holes are radially opened on the inner circumference of the fixed ring. The centrifugal ends of the two insertion holes are respectively connected to the centrifugal ends of the two plug grooves so that the centrifugal ends of the two plug rods can be inserted respectively.

[0012] Two opposing push rods are axially and elastically inserted into the ring surface on the side of the fixed ring away from the air chamber;

[0013] One end of the push rod extends into the insertion hole and presses against the centrifugal end of the plug rod.

[0014] A movable ring is axially movably fitted on the outside of the trachea, located on the side of the fixed ring away from the air chamber. The ring surface of the movable ring facing the fixed ring is fixedly connected to the other end of the push rod.

[0015] A first spring is fitted on the outer side of the push rod, and a second spring is fitted on the outer side of the plug rod, located between the fixed plate and the piston.

[0016] The elastic force of the first spring is greater than that of the second spring.

[0017] When the push rod presses against the stopper rod, causing the piston to move toward the groove and the rubber layer to expand and deform, the second spring gradually stretches and deforms.

[0018] When the push rod is driven by the moving ring to move away from the fixed ring, the push rod disengages from the stop rod, the first spring gradually stretches and deforms, and the second spring gradually returns to its non-deformed state.

[0019] Furthermore, the pressure medium is hydraulic oil.

[0020] Furthermore, a locking rod is concentrically fixed at the end of the tube plug away from the air chamber, and a locking hole is provided on the outer wall of the fixed ring for locking the locking rod.

[0021] Furthermore, several flexible protrusions are equidistantly arranged on the inner circumference of the foot ring.

[0022] The beneficial effects of this utility model are reflected in:

[0023] The inflatable foot ring of this invention can automatically seal and fix the trachea with the tube plug by simply driving the piston to move relative to the plug groove. This avoids the situation where the foot ring leaks air and cannot be used normally by the patient if the tube plug falls off due to damage, fatigue, aging, or incomplete sealing on the trachea.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, and not all of them. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of the utility model without creative effort are within the scope of protection of the utility model.

[0035] Please combine Figures 1 to 7 .

[0036] The pneumatic foot ring includes a foot ring 1 with an air chamber. An air tube 2 is provided on the outer wall of the foot ring 1 to inflate and deflate the air chamber. A plug 3 is detachably provided at the end of the air tube 2 away from the air chamber to block the air tube 2. A groove 12 is formed on the outer periphery of the plug 3.

[0037] A groove 10 corresponding to the position of the slot 12 is formed around the inner circumferential side wall of the trachea 2. A rubber layer 11 is provided at the opening of the groove 10 to completely cover the opening, and a pressurized area is formed between the groove 10 and the rubber layer 11.

[0038] Two opposing plug grooves 6 are radially formed on the outer peripheral sidewall of the trachea 2, with the centripetal ends of the two plug grooves 6 respectively connecting to both sides of the groove 10. A piston 9 is installed in the plug groove 6, and both the pressurization area and the plug groove 6 contain pressure medium.

[0039] By driving the piston 9 to move from the plug groove 6 to the groove 10, the pressure medium in the groove 10 is squeezed, forcing the rubber layer 11 to expand and deform to seal and snap into the groove 12.

[0040] In practice, before use, when inflating, the tube plug 3 is pulled out, and air is inflated into the air chamber of the foot ring 1 through the air tube 2, causing the foot ring 1 to expand into a ring shape. After inflation, the tube plug 3 is used to seal the air tube 2, driving the piston 9 to move from the plug groove 6 to the groove 10, applying pressure to the pressure medium in the plug groove 6 and the groove 10, increasing the pressure in the inflation area, forcing the rubber layer 11 to expand and deform, sealing and locking into the groove 12, thus providing a secondary seal for the tube plug 3. During use, the inflated foot ring 1 is placed near the patient's ankle or heel, leaving the patient's heel or ankle suspended in the air. This prevents pressure on the skin of the heel and ankle of comatose, long-term bedridden, and paralyzed patients, reducing the chance of developing bedsores and alleviating the patient's pain.

[0041] The advantage of this design is that by simply driving the piston 9 to move relative to the plug groove 6, a secondary sealing and fixation of the trachea 2 with the plug 3 inserted can be achieved conveniently and efficiently. This avoids the situation where the foot ring 1 leaks air due to the plug 3 being fatigued, damaged, or accidentally falling off because the plug 3 is not completely sealed on the trachea 2, thus preventing the trachea 2 from being used normally by the patient.

[0042] In one embodiment, a fixed plate 7 is fixed in each of the two plug grooves 6, and a plug rod 8 parallel to the extension direction of the plug groove 6 is slidably inserted on each fixed plate 7. The centripetal end of the plug rod 8 is fixed on the outer wall of the corresponding piston 9.

[0043] Thus, the piston 9 can be driven to move relative to the piston groove 6 by the piston rod 8.

[0044] In one embodiment, a fixed ring 4 is sleeved and fixed on the outside of the trachea 2. Two opposing insertion holes 13 are radially opened on the inner circumference of the fixed ring 4. The centrifugal ends of the two insertion holes 13 are respectively connected to the centrifugal ends of the two plug grooves 6 so as to allow the centrifugal ends of the two plug rods 8 to be inserted respectively.

[0045] Two opposing push rods 14 are axially elastically inserted on the annular surface of the fixed ring 4 on the side away from the air chamber.

[0046] One end of the push rod 14 extends into the insertion hole 13 and presses against the centrifugal end of the plug rod 8.

[0047] A movable ring 5 is axially movably fitted on the outside of the trachea 2, located on the side of the fixed ring 4 away from the air chamber. The side of the movable ring 5 facing the fixed ring 4 is fixedly connected to the other end of the push rod 14.

[0048] A first spring (not marked) is fitted on the outer side of the push rod 14, and a second spring (not marked) is fitted on the outer side of the plug rod 8, located between the fixed plate 7 and the piston 9.

[0049] The elastic force of the first spring is greater than that of the second spring.

[0050] When the push rod 14 presses against the stopper rod 8, causing the piston 9 to move toward the groove 10 and causing the rubber layer 11 to expand and deform, the second spring gradually stretches and deforms.

[0051] When the push rod 14 is driven to move away from the fixed ring 4 by the moving ring 5, the push rod 14 is disengaged from the stop rod 8, the first spring is gradually stretched and deformed, and the second spring gradually returns to the non-deformed state.

[0052] Thus, before inserting the plug 3 into the trachea 2, since the spring force of the first spring is greater than that of the second spring, the push rod 14 always presses against the plug rod 8, and the plug rod 8 always squeezes the pressure medium through the piston 9 (the second spring is always in a state of tension deformation). This keeps the rubber layer 11 in a state of expansion deformation. Therefore, it is necessary to first move the moving ring 5 away from the fixed ring 4 in the axial direction of the trachea 2 (the first spring is stretched and deformed) to drive the push rod 14 away from the plug rod 8. Then the spring force of the second spring is released, pushing the plug rod 8 and the piston 9 to move away from the groove 10, relieving the squeezing force on the pressure medium in the groove 10. Then the rubber layer 11 contracts, avoiding interference with the insertion of the plug 3 into the trachea 2.

[0053] Then, the tube plug 3 can be inserted into the air tube 2, the moving ring 5 is released, the first spring force is released and pushes the moving ring 5 and the push rod 14 close to the fixed ring 4, so that the push rod 14 returns to the state of contact with the plug rod 8, which indirectly causes the rubber layer 11 to expand and deform and get into the slot 12 of the tube plug 3 at this time, so as to perform secondary sealing and fixing of the air tube 2 with the tube plug 3 inserted.

[0054] Preferably, the pressure medium can be hydraulic oil.

[0055] In one embodiment, a locking rod 15 is concentrically fixed at the end of the tube plug 3 away from the air chamber, and a locking hole 16 is provided on the outer wall of the fixed ring 4 for locking the locking rod 15.

[0056] Thus, after the tube plug 3 is removed from the trachea 2, the tube plug 3 can be fixed to the outer periphery of the fixed ring 4 by the locking rod 15 and the locking hole 16, thus completing the storage of the tube plug 3 and preventing it from being lost.

[0057] In one embodiment, a plurality of flexible protrusions 17 are provided at equal intervals along the inner circumference of the foot ring 1.

[0058] This improves the comfort of the inflated foot ring 1 on the patient's ankle or heel.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0060] It should be noted that if the utility model embodiment involves directional indicators (such as up and down), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0061] Furthermore, the meaning of "and / or" throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, if the utility model embodiments involve descriptions of "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. Furthermore, "multiple" refers to two or more. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the utility model.
