Background technique

The compression stockings, that is, the medical compression stockings, are often referred to as elastic stockings in the country, and are products having the functions of preventing and treating venous diseases of the lower extremities and promoting venous blood return to the heart. The compression stockings establish the highest support pressure in the ankle, and the pressure gradually decreases upwards along the legs. For example, the calf is reduced to 50%-80% of the maximum pressure value, and the thigh is reduced to 20%-60% of the maximum pressure value. . This diminishing change in pressure can cause venous return of the lower extremities, effectively alleviating or improving the pressure on the venous and venous valves of the lower extremities.

Among them, the pressure is the dose index of the compression stockings. At present, during the use of the compression stockings, the weft knitted fabric for providing the interface pressure will cause structural slippage due to the multi-directional stretch, thereby affecting the tightening degree, causing the pressure stockings to have excessive or insufficient pressure to varying degrees. And the problem of non-standard pressure distribution directly affects the wearing effect of the compression stockings.

The compression stocking generally comprises a sock 1, a sock 2 and a sock 3, in a first embodiment provided by the invention, the sock 2 of the compression stocking comprises a stabilization zone 11 and a plurality of pressure gradient zones, and at least one pressure difference Area.

Wherein, the stable zone 11 is connected to the stocking foot 3, and the stability zone length parameter La of the stable zone 11 is correspondingly set according to the length parameter LA of the human ankle part, and the circumferential parameter B in the middle of the stable zone 11 is according to the circumference parameter of the thinnest part of the ankle cB corresponds to the setting, the circumference parameter B02 of the upper end of the stabilization zone 11 is correspondingly set according to the circumference parameter cB02 of the upper part of the human ankle (such as the junction of the Achilles tendon and the posterior leg of the calf), and the circumference parameter B01 of the lower end of the stability zone 11 is according to the lower part of the human ankle ( For example, the circumference parameter cB01 of the humeral trochanter is correspondingly set, and the interface pressure in the stabilization zone 11 is kept consistent; the plurality of pressure gradation zones are located between the stabilization zone 11 and the sock 1, and are connected in order from bottom to top, each The interface pressure in the pressure gradient zone gradually decreases from bottom to top, the interface pressure at the junction of adjacent pressure gradient zones remains continuous, and each pressure gradient zone has a preset pressure gradient; and the pressure difference The area is located in a partial area of the sock body, and the interface pressure in the pressure difference zone can be uniformly distributed evenly, or can be distributed in a gradient, and the interface pressure can be greater than that of the sock body connected thereto. Surface pressure may be less than the interfacial pressure stockings body in contact therewith.

In the actual production and manufacturing, the pressure difference zone has a special function corresponding to the location of the patient site or at a specific location, and the location may be located inside the stabilization zone 11 surrounded by the stabilization zone 11, or surrounded by the pressure gradient zone, or located At the junction of the stable zone 11 and the pressure gradient zone, it can be seen that the position of the pressure difference zone and the interface pressure can be selected according to specific functional requirements for specific design. When the pressure difference zone is located between the two pressure gradient zones and the interface pressure is evenly distributed, its function is similar to that of the stabilization zone 11 described above, and can be regarded as another stable zone located at the site.

For example, for a compression stocking with a high pressure level, such as ankle pressure of 34-46 mmHg, the knee pressure has a chance to reach a high pressure of 36.8 mmHg, and the fabric is thicker than the low pressure fabric. When the wearer bends the knee, the tibia high point will Understand greater stress, long-term wear will affect local tissue health and Causes pressure ulcers. In order to avoid this problem, as shown in Fig. 9, in the position corresponding to the knee head in the compression stocking, the first pressure difference area 501 is set by using the plain weave structure, resulting in a relatively small pressure value of the main body area 502 of the compression stocking, which is reduced here. High pressure state.

However, it is not limited thereto, and the pressure difference zone may be disposed at other positions of the compression stocking according to the use. For example, as shown in FIG. 10, in order to reduce the pressure of the axillary portion and increase the local gas permeability, a second pressure difference zone 503 is provided in a portion of the compression stocking that corresponds to the position of the armpit, and the pressure difference zone is applied to the plain weave and the tuck tissue. The mesh hollow structure is formed to form a breathable functional area which is more breathable than the main body region 502 of the compression sock, improves the wearing comfort of the compression stocking, and ensures local tissue health. Therefore, the specific setting position of the pressure difference zone is not specifically limited in the embodiment of the present invention.

In the actual production and manufacturing, the pressure difference zone in the compression stocking can not only realize the pressure change and special function through the structure, but also can be realized by other auxiliary materials, such as using silica gel, hydrogel or other auxiliary materials in a certain form and The thickness is set at the target portion of the compression stocking, and the local pressure size distribution is strengthened or reduced. The pressure difference zone obtained in this way not only realizes the pressure change of the local position, but also improves the characteristics and comfort of the pressure contact surface.

The circumference parameter c B03 is correspondingly set, wherein the circumference parameter B1 at the lower third of the first gradation area 12 is corresponding to the circumference parameter cB1 at the intersection of the human Achilles tendon and the posterior leg muscle;

The middle position of the second pressure grading zone 13 is the corresponding position of the thickest part of the lower leg, and the circumference parameter C of the middle of the second pressure grading zone 13 is correspondingly set according to the circumference parameter cC of the thickest part of the lower leg;

The lower end of the third pressure grading zone 14 (ie, the upper end of the second pressure grading zone 13) is adjacent to the uppermost position of the lower leg and located at the upper portion thereof, and the upper end of the third pressure gradual zone 14 and the lower part of the lower jaw humerus Corresponding to the position, the circumference parameter C01 at the lower end of the third pressure gradation zone 14 is correspondingly set according to the circumference parameter cC01 of the uppermost part of the calf, and the circumference parameter D of the upper end of the third pressure gradation zone 14 is according to the lower part of the tibia of the human knee. The circumference parameter cD is correspondingly set, and at the same time, it is easy to know that the upper end of the third pressure gradation zone 14 is close to the sock 1 and is located at the lower part of the sock 1 , and the circumference parameter D01 of the lower end of the sock 1 is according to the vicinity of the knee under the humerus. The circumference parameter c D01 corresponds to the setting.

In summary, the four main circumference parameters (B, B1, C, and D) of the body 2 are correspondingly set according to the corresponding four main circumference parameters (cB, cB1, cC, and cD) on the human calf.

In addition, it is easy to know that the distance IIb of the center of the heel 32 to the center of the stable zone 11 (the circumference parameter is B) is corresponding to the height Ib between the heel of the foot and the thinnest part of the ankle (the circumference parameter is cB). The distance between the socks 32 and the lower third of the first pressure grading zone 12 (the circumference parameter is B1) is 11b1, and the heel of the human body is in the position of the heel of the lower leg and the lower leg of the lower leg. The circumference parameter is set correspondingly to the height Ib1 between CB1); the distance 11c from the center of the sock 32 to the center of the second pressure gradation zone 13 (the circumference parameter is C), and the thickest part of the heel and the human calf in the standing state of the human body (its The height parameter Ic is set between the circumference parameter cC); the distance 11d from the upper end of the sock 32 to the third pressure gradient zone 14 (the circumference parameter is D), and the heel of the human body under the knee and the lower part of the lower jaw of the human body. The height Id is set between (the circumference parameter is cD).

At the same time, it is easy to know that the length parameter Lb of the first pressure grading zone 12 is correspondingly set according to the length parameter LB of the upper part of the human ankle (the circumference parameter is cB02) to the lowermost part of the human leg (the circumference parameter is cB03), first The interface pressure of the pressure gradient zone 12 is smaller than the interface pressure of the stabilization zone 11; the length parameter Lc of the second pressure gradient zone 13 is based on the lowermost part of the human calf (the circumference parameter is cB03) to the uppermost part of the human calf (the circumference thereof) The length parameter LC is corresponding to the length parameter LC; the length parameter Ld of the third pressure gradient zone 14 is based on the uppermost part of the human calf (the circumference parameter is cC01) to the lower part of the knee under the humerus (the circumference parameter is The length parameter LD of cD) is set correspondingly.

In addition, the length parameter of the pressure gradient zone can also be correspondingly set according to the pressure gradient of the compression stocking from the ankle to the knee, and the height Le of the pressure stocking 1 can also be adjusted according to requirements. Therefore, the specific embodiments of the present invention are not specifically limited.

In the production process, the LONATI LA-40ME computerized seamless sock machine (the diameter of the circular machine is 4 inches, the machine number is E28, with 4 looping systems, a total of 352 needles), and the elastic package with different linear density is used.

In practical applications, the ribbed tissue is used to weave the sock 1, and the plain weave is used to weave the toe 31 and the toe 32. At the same time, in order to reduce the feeling of imprisonment when the toe is worn, the pressure stockings 1 changes the design of the traditional double Luokou, and adopts a single-nozzle structure, so that the stocking 1 becomes light and thin and the elastic force is reduced, thereby avoiding the socks in the prior art. The phenomenon of the tourniquet effect on the mouth makes the compression stockings comfortable to wear without slipping off.

Specifically, the tension feeders 43 are used to control and adjust the tension state of the elastic pad yarns 42; the PYF active yarn feeding controller 44 controls the amount of yarn fed to the yarn feeders 45 by adjusting the gear rotation speed, that is, participating in the weaving. The amount of elastic upholstery yarn 42, the slower the rotational speed of the PYF active feed controller 44, the less elastic liner yarn 42 is woven into the fabric, and the fabric has a greater tension than the fabric with more liner yarn entry. The resulting interface pressure is correspondingly larger and more difficult to stretch; the needle 47 is provided with a knitting needle 46; the stepping motor controls the size of the knitting coil and the fabric density by adjusting the height of the needle 47, the larger the value, correspondingly The larger the size of the coil, the smaller the density of the fabric; the movement path of the knitting needle 46 on the cylinder 47 is controlled by the needle selector and the cam device, wherein the position of the looping triangle can also control the coil size and the density of the fabric.

When the above-mentioned compression stocking weaving process is carried out using the seamless hosiery machine, the elastic lining yarn 42 penetrates the first yarn supplying system and the third yarn supplying system to provide the necessary elastic force and pressure for the body woven fabric for knitting the hosiery head 31. And the yarn of the heel 32 is threaded into the fourth yarn supplying system for knitting, and the knitting yarn penetrates into the first yarn supplying system, the second yarn supplying system, the third yarn supplying system, and the fourth yarn supplying system to provide the pressure socks. The body layer of the sock is woven with the layer of socks and socks.

In the actual actual production process, when the above-mentioned compression stocking weaving process is implemented, in order to generate the gradient pressure which gradually decreases from the stable area 11 to the corresponding part of the stocking, the number of knitting lines and the machine parameters are respectively performed in different functional sections of the sock body. Set to achieve the required dimensional requirements in the longitudinal length and the circumference parameter requirements in the circumferential direction, as well as the pressure requirements:

Stabilization zone 11, the size (length parameter and circumference parameter) is set according to the size of the human ankle part, the machine knitting number is 50, the stepping motor is set to 550, and is in the first yarn supplying system and the third yarn supplying system. The PYF active feeding controller speed is 850;

The first pressure gradation zone 12, the size (length parameter and circumference parameter) is set according to the size of the upper part of the human ankle to the lowermost part of the human calf, the number of machine knitting is 60, and the stepping motor setting is gradually increased from 550 to 650, the PYF active feeding controller speed setting of the first yarn supplying system and the third yarn supplying system is gradually increased from 850 to 1000;

The second pressure gradient zone 13, the size (length parameter and circumference parameter) is set according to the size of the thickest part of the human calf to the uppermost part of the human calf, the number of machine knitting is 40, and the stepping motor setting is gradually from 650. Increase to 800, further increase the coil size, while increasing the PYF active yarn feeder speed setting in the first yarn supply system and the third yarn supply system from 1000 to 1400, further reducing the compressive force of the fabric;

The third pressure gradual zone 14, the size (length parameter and circumference parameter) is set according to the size of the upper part of the human calf from the uppermost part of the lower leg to the lower part of the lower part of the knee, and the number of machine knitting is 70, and the stepping motor is set to maintain 1400. At the same time, the PYF active feeding controller speed setting of the first yarn supplying system and the third yarn supplying system is maintained at 1400, and the fabric elastic force and compression force are controlled.

Sock 1, the width Ld of the sock 1 can be adjusted according to the style (usually 2-3cm), the machine knitting number is 28, the stepping motor setting is kept at 720, in the first yarn supply system and the third supply The PYF active feed controller speed setting of the yarn system is maintained at 1300.

The resulting sock of the compression stockings forms a gradient distribution where the interfacial pressure between the stabilizing zone 11 and the limb is greatest, and then gradually decreases along the leg up to the knee pressure. Through the professional leg mold pressure test, the body part is at the thinnest part of the human ankle (corresponding to the circumference parameter B), the upper part of the upper part of the human ankle and the posterior leg of the calf (corresponding to the circumference parameter B1), the thickest part of the human calf ( The interface pressures corresponding to the circumference parameter C) and the lower part of the human knee (the lower part of the tibial tuber) (corresponding to the circumference parameter D) are “20.9±1.47mmHg”, “17.8±1.3mmHg”, “13.4±1.5” respectively. mmHg" and "12.2 ± 1.2 mmHg". Among them, 1mmHg=133.33 Pascal, which is the unit of pressure or pressure value expressed in millimeters of the height of the mercury column, which is often used to indicate the pressure dose of the compression stocking product. The above-mentioned compression stockings pass through four main circumferences (B, B1, C and D) from the ankle to the knee, and the pressure gradient is decremented. The ratio is approximately 100%, 85%, 64%, 58%, in accordance with RAL-GZ387/1.

Apply the above preparation method, adjust the linear density of the elastic yarn, and match the parameter setting of the seamless sock machine (caliber size, machine number, PYF active feeding controller, stepping motor, looping triangle, weaving Number, etc., adjust the elasticity, tension, yarn feeding amount, braiding length, coil size and fabric density of the liner yarn to meet the needs of the human body for the size, pressure distribution and pressure of the compression stockings with different body types and symptoms. .

At the same time, by changing the length and shape of the body, the same compression stocking structure and compression stocking weaving process can also be used for the weaving of pressure fabrics such as stockings and tights. The elastic covered yarn used can also be woven by using other elastic wrapping yarns or functional materials, such as silver ion polyamide coated yarn with antibacterial function, polyester wrapping yarn, etc. Therefore, the present invention is specific to the type of compression stockings. No specific restrictions.

The pressure is an important dose indicator for compression stockings. How to achieve the required pressure dose by adjusting the material elasticity, knitting parameters and machine settings is essential for achieving its medical function. It can be seen from the above technical solution that the compression stocking provided by the first embodiment of the present invention is made by weaving a seamless round sock machine, and the interface pressure of the compression stocking is distributed from the ankle to the sock in a stepwise manner. The local target site increases the pressure differential zone (enhanced or weakened interface pressure) for the patient. It can be seen that the present invention achieves an accurate pressure gradient, and particularly sets a differentiated pressure region for the localized patient position and meets the gradient requirement, and at the same time, sets a weak pressure zone and a ventilated zone at a specific location to improve wearing safety and comfort.

In addition, in the weaving process of the compression stocking provided by the present invention, different linear density elastic yarns are used according to the shape and symptom stage of the lower limbs of the human body, and the setting of the stepping motor, the tension controller, the number of knitting rows, and the knitting structure parameters are The sock body is adjusted in form and pressure and the application area, so that the pressure sock achieves the required pressure distribution, pressure and desired function, and improves the current pressure sock pressure dose instability, single function and wearing discomfort. The above-mentioned compression stocking weaving process can be used for the development and weaving of related medical compression pressure textiles.

However, in actual use, the pressure of the compression stockings in different directions in the same circumference of the leg is different, which is related to the structure and surface curvature of the human lower limb cross section. The pressure of the compression stocking along the saphenous vein is smaller than that of the other front legs, the outer part and the rear part of the same circumference, which causes a problem of insufficient effective pressure dose to some extent.

Therefore, in order to further optimize the technical solution in the first embodiment, the present invention also provides In the second embodiment, the pressure shoe in the second embodiment has the following design structure in addition to the design structure in the first embodiment: the stability zone 11 includes a stable zone main body and a stable zone longitudinal pressure belt, and the stability zone is longitudinally increased. The interface pressure of the pressure belt is greater than the interface pressure of the main body of the stability zone; the first pressure gradient zone 12 includes a first pressure zone body and a first longitudinal pressure zone. On the same circumference, the interface pressure of the first longitudinal pressure zone is greater than the first The interface pressure of the main body of the pressure zone; the second pressure grading zone 13 includes a second pressure zone body and a second longitudinal pressure zone. On the same circumference, the interface pressure of the second longitudinal pressure zone is greater than the interface pressure of the body of the second pressure zone The third pressure grading zone 14 includes a third pressure zone body and a third longitudinal pressure zone. On the same circumference, the interface pressure of the third longitudinal pressure zone is greater than the interface pressure of the body of the third pressure zone. Moreover, the stable zone longitudinal pressure belt, the first longitudinal pressure belt, the second longitudinal pressure belt and the third longitudinal pressure belt are located at positions corresponding to the inside of the body of the human body, and the interface pressure is sequentially decreased. It can be seen that the sock body of the compression stocking in the second embodiment comprises two parts, one part is the body body 401, and the other part is a longitudinal pressure belt of the stable zone, a first longitudinal pressure belt, a second longitudinal pressure belt and The longitudinal belt 402 formed by the third longitudinal pressure belt has the interface pressure of the longitudinal belt 402 being greater than the interface pressure of the sock body 401 of the same circumference. Please refer to the structural diagram of the compression stockings shown in FIG. 6 and the sectional section of the human calf wearing the compression stockings shown in FIG. 7, wherein the shaded portion is the longitudinal belt 402 and the rest is the body body 401. However, it will be readily apparent to those skilled in the art that the longitudinal strip 402 can also be located in other directions, such as the outside of the calf. Therefore, the present invention is not specifically limited.

In the study of how to solve the problem of insufficient effective pressure dose of pressure stockings, we carried out a series of test evaluation work. In the standard test environment (temperature 21 ± 1 ° C, relative humidity: 65 ± 2%), apply the elastic tensile tester (MY-9000-S) at a maximum load of 44 Newtons (about 4500 grams of force) and 100mm / Constant speed of min The tensile recovery test was carried out along the latitude and warp direction of the five kinds of pad elastic fabrics of the standard specifications. The test results show that the warp and weft stretch and recovery performance of different fabrics due to the difference of the gasket structure There are significant differences.

Therefore, in the second embodiment, the first swatch 201 and the second swatch 202 having different lining structures are selected according to the mechanical performance of the woven fabric and the specific requirements for the wearing of the pressure hosiery and the position of the patient to generate the circumference. The pressure recovery socks with different pressure effects in directions, the tensile recovery test results of the first swatch 201 and the second swatch 202 are shown in FIGS. 5-1 and 5-2, wherein the abscissa S is a tensile displacement (unit) In millimeters), the ordinate F is the tensile force (in Newtons). Figure 5-1 shows the first swatch under the tension of 44 cattle. The mechanical properties of the first latitudinal stretching a1 of 201 and the first latitudinal tensile recovery a2, and the mechanical properties of the second latitudinal stretching b1 and the second latitudinal tensile recovery b2 of the second swatch 202; 5-2 shows the mechanical properties of the first warp stretch a3 of the first swatch 201 and the first warp stretch recovery a4, and the second warp stretch b3 and the second warp direction of the second swatch 202. Stretching restores the mechanical properties of b4. It can be seen that the second swatch 202 has a smaller degree of stretch in the warp and weft directions than the first swatch 201, that is, under the same force, a smaller tensile displacement is produced.

8-1 and 8-2 are respectively arranged on the structure of the longitudinal belt 402 and the body body 401, wherein

In a second embodiment, different pad structures are used in combination for weaving the body sock, and a longitudinal band 402 of 5-6 cm is provided along the inner side of the body so that a pressure increase with a gradient decreasing effect from the stabilizing zone 11 to the underside of the sock is obtained. Area. According to the leg model test, from the thinnest part of the human ankle (corresponding to the circumference parameter B) to the lower part of the lower part of the human body (corresponding to the circumference parameter D), the pressure of the longitudinal belt 402 is lower than that of the same circumference. The pressure of the main body 401 is 26% - 36% higher. It can be seen that the setting of the longitudinal belt 402 not only satisfies the gradient decrement requirement from large to small, but also enables the compression stocking to achieve the performance requirement of the same circumferential pressure difference.

Specifically, referring to FIG. 7, the gradient decreasing pressure of the longitudinal belt 402 from the lower part of the human ankle to the lower part of the human body is: 26.1 mmHg (the thinnest part of the human ankle, the corresponding circumference parameter is B), 24.4 mmHg (the upper part of the human ankle) At the junction of the iliac crest and the posterior leg of the calf, the corresponding circumference parameter is B1), 20.6mmHg (the thickest part of the human calf, the corresponding circumference parameter is C) and 10.1mmHg (the lower part of the lower part of the humerus in the lower part of the human knee, the corresponding circumference parameter is D). Correspondingly, the pressure in the same dimension on the body body 401 is 20.1 mmHg, 18.0 mmHg, 16.3 mmHg, and 10.9 mmHg, respectively.

The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments are obvious to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the present invention will not be limited to the embodiments shown herein, but It is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
