Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a leg pressure sleeve device. Background Art

[0002] Intermittent compression devices are a type of equipment used for medical treatment. Their research background involves multiple fields such as circulatory system diseases, postoperative rehabilitation, elderly care, and athlete rehabilitation. This technology is based on a deep understanding of blood circulation. Through intermittent inflation and deflation of air bags, gradually increasing and decreasing air pressure is applied to the patient's limbs to simulate the natural blood flow process of the human body, promote blood circulation, reduce edema, etc. The commonly used intermittent pneumatic compression device is a leg sleeve made of non-woven adhesive bandage. The existing leg sleeve has a fixed length problem. This length is usually set to the average leg circumference. However, due to individual differences among patients, for patients with smaller leg circumferences, they need to wrap the leg sleeve multiple times to ensure fixation, which increases the wrapping area of ​​the leg sleeve and affects the breathability. On the contrary, patients with larger leg circumferences need to use force to fix the leg sleeve, and this process may cause compression to the patient's leg muscles. This fixed length design cannot meet the needs of different patients, especially when the individual differences between the calf circumference and the thigh circumference are more obvious. Utility Model Content

[0003] In order to solve the above technical problems, the utility model proposes a leg pressure sleeve device, in which folding parts with adjustable length are arranged on both sides of the airbag, so that the leg sleeve has a wider adaptability and can be flexibly adjusted according to the size of the patient's leg circumference, which not only ensures the fixing strength but also reduces the impact of winding on breathability, providing patients with a more comfortable treatment experience.

[0004] The technical solution of the utility model to solve the above problems is: a leg pressure sleeve device, which is special in that:

[0005] Including thigh and calf sleeves;

[0006] The thigh leg sleeve and the calf leg sleeve have the same structure;

[0007] An air bag is arranged in the middle of the thigh cuff, Velcro is arranged at both ends of the thigh cuff, and air hole arrays are arranged between the Velcro and the air bag on both sides, which are respectively a first air hole array and a second air hole array. The two ends of the thigh cuff are connected by Velcro to achieve adjustable length.

[0008] Furthermore, the thigh leg cover and the calf leg cover are connected by a connecting belt.

[0009] Furthermore, the two ends of the connecting belt are detachably connected to the thigh leg cover and the calf leg cover through Velcro respectively.

[0010] Furthermore, the connecting belt is an elastic belt. During the simultaneous pressurization of the thigh and calf, the connecting belt buffers the limb movements such as the bending of the knee, which avoids the problem that the integrated airbag cannot fit the shape of the leg. When only one part of the thigh or calf needs to be pressurized, it is only necessary to untie the connecting belt and leave the airbag in the required part, so that pressurization can be achieved separately as needed, which is more suitable for different treatment needs of patients.

[0011] Furthermore, the airbag is a capsule cavity formed by high-frequency welding of two layers of TPU films, and the airbag is divided into multiple connected uniform areas by indentation lines, thereby achieving a more uniform pressurization effect.

[0012] Furthermore, the TPU film of the outer layer is thicker, and the TPU film of the inner layer is thinner, so that unilateral expansion can be achieved after pressurization, and multiple sealing lines are set in the inflation air path and around the airbag. The airbag film thickness design of thick outer side and thin inner side is adopted to achieve unilateral pressurization, better fit the leg shape, and improve pressurization efficiency.

[0013] Furthermore, ventilation holes are cut in the uniform area of ​​the airbag segmentation by a high-frequency synchronous fusing process to improve the air permeability of the leg cover.

[0014] Furthermore, the first pore array and the second pore array on the thigh leg sleeve are symmetrically arranged about the bladder cavity; the first pore array includes a plurality of strip pores in the array. When the patient wears the leg sleeve, the strip pore arrays on both sides can overlap each other, and the overlapping strip arrays can adjust the horizontal length according to the patient's leg circumference to ensure breathability and adaptability.

[0015] Furthermore, a folding hole is provided in the middle of the thigh leg cover, and the folding hole is a strip-shaped hole and is located between the first air hole array and the second air hole array.

[0016] Furthermore, the first air hole array and the second air hole array are respectively provided with Velcro on both sides in the width direction.

[0017] Advantages of the utility model:

[0018] The utility model provides a leg pressure sleeve device, which solves the problem of the fixed length of the existing leg sleeve by introducing a folding part design with adjustable length, improves the adaptability of the leg sleeve, and enables it to be flexibly adjusted to meet the leg circumference requirements of different patients; through the design of the connecting belt, the thigh sleeve and the calf sleeve can be connected as a whole or pressurized separately, effectively solving the problem that the entire leg sleeve is scrapped after a single airbag is damaged in the existing one-piece leg sleeve, reducing the cost of replacing the entire leg sleeve, and providing patients with more flexible treatment options; adopting the airbag indentation line segmentation design, reducing the amount of air required for airbag inflation, improving the inflation speed, ensuring that the airbag better fits the leg shape, achieving a uniform pressurization effect, and improving the pressure resistance of the airbag; by setting a breathable hole array and a strip air hole array, the air permeability of the entire leg sleeve is improved, leg sweat is discharged in time, and the patient's discomfort is reduced. The airbag membrane thickness design is thick on the outside and thin on the inside, achieving unilateral pressurization, better fitting the leg shape, and improving the pressurization efficiency.

[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents the selected embodiments of the utility model.

[0023] Example

[0024] See also Figure 1 and Figure 2The utility model provides a leg pressure sleeve device, comprising a thigh sleeve and a calf sleeve; the thigh sleeve and the calf sleeve have the same structure, and the size can be adjusted according to actual needs.

[0025] The structure of the thigh cuff is explained below.

[0026] See also Figure 1 The middle part of the thigh cuff is the airbag area, Velcro is provided at both ends of the thigh cuff, and air hole arrays are provided between the Velcro on both sides and the airbag, which are respectively the first air hole array and the second air hole array. The two ends of the thigh cuff are connected by Velcro and the length is adjustable. The Velcro at both ends of the thigh cuff includes Velcro 2 hook surface 7 arranged on the inner surface, and Velcro 2 fur surface 10 arranged on the outer surface. After the two are bonded, the thigh cuff is fixed on the thigh. The folding part with adjustable length makes the cuff more adaptable and can be flexibly adjusted according to the size of the patient's leg circumference, which not only ensures the fixing strength, but also reduces the influence of winding on air permeability, providing patients with a more comfortable treatment experience.

[0027] As a preferred embodiment of the present invention, see Figure 1 and Figure 2 The thigh sleeve and the calf sleeve are detachably connected via a connection 8. The utility model connects the thigh sleeve and the calf sleeve as a whole by means of a connection belt 8 arranged at the lower end of the thigh sleeve, plays a buffering role and can be pressurized separately as needed. When any of the airbags is damaged and leaks, there is no need to replace the entire pressure sleeve device, only a single damaged sleeve needs to be replaced, thus saving costs.

[0028] As a preferred embodiment of the present invention, see Figure 2 The two ends of the connecting belt 8 are detachably connected to the thigh leg sleeve and the calf leg sleeve through the connecting belt Velcro 11. The lower part of the thigh leg sleeve is connected to the calf leg sleeve as a whole through the connecting belt Velcro. The connecting belt can be an elastic belt. During the simultaneous pressurization of the thigh and calf, the connecting belt buffers the limb movements such as the bending of the knee, which avoids the problem that the integrated airbag cannot fit the shape of the leg. When only one part of the thigh or calf needs to be pressurized, it is only necessary to untie the connecting belt and leave the airbag in the required part. Therefore, it can achieve pressurization on demand, which is more suitable for different treatment needs of patients.

[0029] As a preferred embodiment of the present invention, see Figure 1The airbag is a bag cavity formed by high-frequency welding of two layers of TPU film. The air nozzle 1 of the airbag is arranged on the outer surface of the leg cover. The airbag is divided into a plurality of connected uniform areas by the high-frequency indentation line 3, so that the airbag can better fit the shape of the leg, improve the comfort of pressurization, and achieve a uniform pressurization effect. By dividing the airbag area, the amount of air required for inflation is reduced, and the inflation speed is increased.

[0030] Specifically, during the preparation of the airbag, two layers of TPU film with a thicker outer layer and a thinner inner layer are high-frequency welded. After pressurization, the thinner side is expanded, and multiple high-frequency indentation lines 3 are set in the inflation air path and around the airbag for sealing, dividing the leakage-prone position into multiple independent welding areas, so that even if part of it is detached, it will not affect the overall sealing effect.

[0031] As a preferred embodiment of the present invention, see Figure 1 During the preparation of the airbag, a high-frequency synchronous fusing process is used to weld the two layers of TPU film to form a bag cavity while cutting a ventilation hole array 4 at a specific position in the airbag to improve the breathability of the leg cover. The leg cover is made of polyester mesh cloth, which greatly improves the breathability of the entire leg cover.

[0032] As a preferred embodiment of the present invention, see Figure 1 and Figure 2 The first pore array and the second pore array on the thigh leg sleeve are symmetrically arranged about the bladder cavity; the first pore array includes a plurality of strip pores in the array. When the patient wears the leg sleeve, the strip pore arrays on both sides can overlap each other, and the overlapping strip arrays can adjust the horizontal length according to the patient's leg circumference to ensure breathability and adaptability.

[0033] The leg sleeve adopts a breathable hole array 4 and a strip-shaped air hole array 2 to improve the overall breathability of the leg sleeve, discharge leg sweat in time, and reduce patient discomfort. The combined application of these designs improves the overall performance of the intermittent compression therapy device in terms of adaptability, flexibility, treatment effect and patient experience.

[0034] See also Figure 1 and Figure 2In the leg sleeve design, the utility model does not set a pressurized airbag on the front part of the leg, especially in the calf. The airbag is set to pressurize the gastrocnemius muscle on the back of the calf. A strip air hole array 2 is set on the front side of the leg. The strip air hole array 2 is symmetrical about the airbag. When the folding part is adjusted to adapt to patients with different leg circumferences, the length of the strip air holes can also be adjusted to achieve the adjustability of the breathable area along the leg circumference. In addition, the existing pressurization device uses two layers of equal thickness membranes to weld to obtain an airbag, which will inflate to both sides when inflated, but only the side close to the patient's limbs is effectively pressurized. Therefore, the utility model designs the thickness of the airbag membrane, using a thick TPU membrane on the outside and a thin TPU membrane on the inside, and performs unilateral pressurization, which can better fit the shape of the leg. This design also reduces the overall thickness of the airbag, improves the comfort of treatment, reduces the amount of inflation, and improves the speed and efficiency of pressurization.

[0035] As a preferred embodiment of the present invention, see Figure 1 The middle part of the thigh leg cover is provided with a folding hole 9, which is a strip hole and is located between the first air hole array and the second air hole array. Considering the sensitivity of the position of the numbness of the posterior thigh, the folding hole 9 helps to reduce the pressure on the numbness and improve comfort. This is particularly important for long-term wear, and the design of the air holes can achieve a ventilation effect. The first air hole array and the second air hole array on the right side of the leg cover are respectively provided with Velcro 1 fur surface 6 on both sides in the width direction, and Velcro 1 fur surface 6 is provided in the middle of Velcro 1 hook surface 5. Velcro 1 fur surface 6 and Velcro 1 hook surface 5 can be bonded with Velcro 2 fur surface 10 on the outer side of the leg cover, which is convenient for adjusting the length of the leg cover.

[0036] The above description is only an embodiment of the present invention, and is not intended to limit the protection scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly used in other related system fields, are also included in the protection scope of the present invention.
