Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically a tensioning device for an air pressure therapy device. Background Technology

[0002] Venous thrombosis is a common peripheral vascular disease that easily leads to venous valve insufficiency and pulmonary embolism, a condition that has always been a major concern in clinical practice. The air wave pressure circulation therapy device primarily works by sequentially and repeatedly inflating and deflating a multi-chambered airbag, creating circulatory pressure on the limbs and tissues. During pressurization, the hydrostatic pressure of the tissue fluid significantly increases through interstitial pressure transmission, thereby overcoming capillary pressure and interstitial colloid osmotic pressure, promoting the return of tissue fluid into the veins and lymphatic vessels. The uniform and orderly compression from the distal to the proximal end of the limb promotes blood and lymph flow and improves microcirculation, accelerating the return of limb tissue fluid and helping to prevent venous thrombosis and limb edema.

[0003] In related technologies, air circulation pressure therapy devices involve placing an airbag (bag) on ​​the patient's limb before use. An air pump then drives the airbag to expand repeatedly to achieve the treatment. Currently, the airbag is mainly formed using Velcro (rolling the airbag into a tube and securing it with Velcro). However, medical professionals have found that after prolonged use, dirt easily accumulates on the Velcro surface, hindering its adhesion and causing problems with the airbag unfolding during subsequent rolling. Furthermore, for patients of different body types, the Velcro may not fasten properly (e.g., obese patients) or may not fit snugly (e.g., thin patients), indicating limitations in the technology. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a tensioning device for an air pressure therapy device.

[0005] The technical solution adopted by this utility model is as follows: a tightening and loosening device for an air pressure therapy device, comprising a wrapping air bag, an inflation connector, and a tightening and loosening mechanism, wherein there are several tightening and loosening mechanisms, which are distributed at intervals along the length of the wrapping air bag. Each tightening and loosening mechanism includes a strap and male and female buckles that can be inserted and mated. The strap is disposed on the outer circumference of the wrapping air bag, and the two ends of the strap can be retracted and wrapped around the male and female buckles respectively, so as to realize the adjustment of the tightness of the tightening and loosening mechanism on the wrapping air bag. Multiple sets of adhesive components are also arranged at intervals along the length of the wrapping air bag.

[0006] In a preferred embodiment, the opposite ends of the male and female buckles are respectively provided with a shaped buckle head adapted to the wrapping of the strap.

[0007] In a preferred embodiment, the adhesive component includes a hook and loop fastener and a loop fastener that can be adhesively mated. The hook and loop fastener is disposed on one end face of the air bag along the length direction, and the loop fastener is disposed on the other end face of the air bag along the length direction and is collinear with the hook and loop fastener.

[0008] In a preferred embodiment, the air bag is divided into multiple air chambers, one end of the inflation connector is provided with an air pipe that is connected to each of the multiple air chambers, and the other end of the inflation connector is connected to an external air pump.

[0009] In a preferred embodiment, the airbag includes, from the outside to the inside, an outer fabric layer, an airbag layer, an electric heating element, and an inner fabric layer. The airbag layer is made of TPU material and has multiple chambers formed by a segmented hot pressing process.

[0010] In a preferred embodiment, the inner fabric layer is made of memory fabric material, and the outer fabric layer is made of 210D composite material.

[0011] In a preferred embodiment, the electric heating element is a flexible electric heating sheet.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: multiple sets of tightening mechanisms are designed in the outer circumference of the air bag. After winding, Velcro is used to achieve initial adhesion and fixation, and then the straps in the tightening mechanism are used for secondary binding. With the double fixing method, the air bag will not unfold during use. At the same time, the tightening mechanism can also adjust the tightness for patients of different body types to ensure that the patient's limbs can fit the air bag, thereby achieving the best therapeutic effect.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0024] A tensioning device for an air pressure therapy device, as shown in the reference. Figure 1-4 The system includes an air bag 100, an inflation connector 200, and a tightening mechanism 300. Several tightening mechanisms 300 are distributed at intervals along the length of the air bag 100. Each tightening mechanism 300 includes a strap 320 and interlocking male and female buckles 330 and 310. The strap 320 is located on the outer periphery of the air bag 100, and both ends of the strap 320 can be wound around the male and female buckles 330 and 310 respectively to adjust the tightness of the tightening mechanism 300 on the air bag 100. Multiple sets of adhesive components are spaced along the length of the air bag 100. Multiple sets of tightening mechanisms 300 are designed around the outer periphery of the air bag 100. After winding, the adhesive components achieve initial bonding and fixation, and the straps 320 in the tightening mechanisms 300 provide secondary securing. This dual-fixation design prevents the air bag from unfolding during use. Furthermore, the tightening mechanisms 300 can adjust the tightness for patients of different body types to ensure the patient's limb fits snugly against the air bag, achieving optimal therapeutic effect. The male buckle 330 and female buckle 310 can adopt the buckle structure found in current backpack straps; specific models are not limited here.

[0025] Specifically, the number of tensioning mechanisms 300 can be adjusted according to the size of the air bag 100, but there must be at least one.

[0026] Furthermore, the opposite ends of the male buckle 330 and the female buckle 310 are respectively provided with a shaped buckle head 340 adapted to wrap around the strap 320. The shaped buckle head 340 can connect the strap 320 together, and the tightness of the tensioning mechanism 300 can be adjusted by adjusting the length of the strap 320. The combination of the shaped buckle head 340 and the strap 320 is a commonly used and well-known technology. How to achieve adjustment and fixation will not be described in detail here.

[0027] Furthermore, the adhesive component includes a hook-and-loop fastener 110 and a rough hook-and-loop fastener 120 that can be adhesively mated. The hook-and-loop fastener 110 is located on one end face of the air bag 100 along its length, and the rough hook-and-loop fastener 120 is located on the other end face of the air bag 100 along its length and is collinear with the hook-and-loop fastener 110. After the air bag 100 is wound into a sleeve shape, the hook-and-loop fastener 110 and the rough hook-and-loop fastener 120 can be used to achieve initial adhesive fixation of the air bag 100. Of course, it is understandable that if the adhesive component still meets the usage requirements and the patient's body shape can also fit the air bag 100, then the adhesive component can be used alone for fixation. Specifically, the number of adhesive components can be adjusted according to the size of the air bag 100, but at least two.

[0028] Furthermore, the air bag 100 is divided into multiple air chambers, and one end of the inflation connector 200 is provided with an air pipe that is connected to the multiple air chambers respectively. The other end of the inflation connector 200 is connected to an external air pump (not shown in the figure).

[0029] Furthermore, the airbag 100 comprises, from the outside to the inside, an outer fabric layer 101, an airbag layer 102, an electric heating element 103, and an inner fabric layer 104. The airbag layer 102 is made of TPU material and has multiple chambers formed by a segmented hot pressing process. The use of TPU material instead of traditional 210D material in the airbag layer 102 results in lower costs and a simpler processing technology. At the same time, TPU material has good anti-aging properties and can maintain stable performance during long-term use (expansion), which can extend the service life of the airbag 100.

[0030] Furthermore, the inner fabric layer 104 is made of memory fabric material, and the outer fabric layer 101 is made of 210D composite material. The memory fabric material can deform according to its initial shape and recover its original shape under specific conditions, so as to meet the deformation requirements as the air bag 100 expands. At the same time, due to the soft and comfortable characteristics of the memory fabric itself, it can be more comfortable to use.

[0031] Furthermore, the electric heating element 103 is a flexible electric heating pad. Using the electric heating element 103, heat therapy can be performed on the patient simultaneously, improving the patient's comfort. The encasing air bag 100 also contains a built-in thermistor (not shown in the figure) for temperature monitoring. The thermistor, electric heating element 103, and air pump are electrically connected to the external therapeutic device main unit (not shown in the figure). Since flexible electric heating pads are already known technology, specific models and structures will not be described further.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
