Description

The present invention relates to medical elastic stockings used for the purpose of promoting venous return, such as reducing or preventing venous blood and lymphatic stasis in the extremities.

Medical elastic stockings, whose middle category belongs to physical therapy machinery and equipment and whose general name is elastic stockings, are used for the purpose of promoting venous return, such as reducing or preventing venous blood and lymphatic stasis in the extremities. , It is stipulated that it has the function of gradually applying compression from the periphery to the center. This compression stockings is indispensable for the treatment of venous return disorders such as varicose veins and sequelae of venous thrombosis, and is also used for the treatment of lymphedema. It is also useful for preventing venous thrombosis and varicose veins, and is also useful for preventing swelling of the lower limbs for people who work for a long time, the elderly, and females.

Various proposals have been made to enhance the function and performance of such elastic stockings. For example, in Patent Document 1, a sock-type orthopedic tool used for treating a cardiovascular disease of the lower limbs, suitable for pressing and supporting all or part of the leg, and having a function of gradually reducing the compressive force from the ankle. It has a compressible continuous cylindrical knitted part that covers the leg excluding the foot or heel, and a non-compressible tubular part that is connected to this and can cover at least the foot part without pressure. A plastic surgery tool has been proposed. This orthopedic tool does not apply compressive force to the foot and has a terminal opening in the sock, so the wound can be examined without removing the sock, and the doctor can easily compress it. It is said that it is possible to readjust the mounting condition by lifting a certain part.

Patent Document 2 describes a medical stocking in which a stretchable knitted fabric knitted using a ground thread and an insertion thread having a stronger compressive force than the ground thread, forming at least a leg portion, from the ankle to the calf. The compression force is gradually weakened in the order of the ankle region to the lower end, the lower leg region from the lower end of the calf to the knee, and the thigh region from the knee to the base of the leg. The ratio is (thread length of the ground thread): (thread length of the inserted thread) = 4.3 to 6.0: 1 in the lower leg region, and (thread length of the ground thread): (thread length of the inserted thread) in the thigh region. Medical stockings with a value of 3.3 to 5.0: 1 have been proposed. This medical stocking consists of a toe area, a foot area, an ankle area, a lower leg area, and a thigh area, and is knitted by inserting an insertion thread having a stronger compressive force than the ground thread into the plain knitting structure (flat knitting structure) of the ground thread. Since it is made of elastic knitted fabric, it is said that it is highly breathable and breathable and can prevent stuffiness while maintaining the pressure required for stockings for treatment of lymphoedema and the like.

On the other hand, since a fall accident of a patient wearing elastic stockings has become a problem, elastic stockings that can prevent the fall have been proposed. For example, Patent Document 3 describes a medical elastic stockings for preventing the onset of venous thromboembolism, which has a compressible covering portion formed so as to press and cover a leg portion below the knee portion. Medical elastic stockings have been proposed in which the heel and toe of the covering are cut and exposed. It is said that this medical elastic stockings can solve the problem of falling due to slipping when wearing the conventional medical elastic stockings, and does not lose the original effect of preventing the onset of venous thromboembolism. The blood flow velocity in the lower limbs of the conventional medical elastic stockings with the heel and toe covered and the medical elastic stockings according to the present invention are statistically significant after 20 minutes and 40 minutes. It is said that no difference was found.

For medical elastic stockings, it is necessary to check the skin and nails of the toes for discoloration and confirm whether they are used properly. Therefore, as shown in Patent Documents 1 to 3, many medical elastic stockings have exposed toes. However, since the plastic surgery tool described in Patent Document 1 does not apply a compressive force to the foot, the terminal opening is likely to be turned over and may cause a trip or a fall. The medical elastic stockings described in Patent Documents 2 or 3 have problems such as cold toes because the compressive force also acts on the feet, and there is a risk that the terminal opening may be turned over.

In addition, medical elastic stockings are formed so that the highest compression force acts on the ankle and a gradual compression force acts toward the knee or upper leg, and the strength of the compression force is high. The degree is indicated by the compression force of the ankle. In the treatment of varicose veins and venous thrombosis sequelae, it is said that elastic stockings with a compression force of 30 to 40 mmHg are required, and if the skin is prone to hardening, pigmentation or ulceration, a compression force of 40 to 50 mmHg is required. Elastic stockings to have are needed. However, it is not easy and painful for elderly people and patients with joint disorders to wear compression stockings with a compression force of 30 to 50 mmHg.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. The elastic stockings according to the present invention can be used as elastic stockings that cover the legs from the hallux to the knees or the upper legs. As shown in FIG. 1, the elastic stockings 10 have a compression knitted fabric portion 11 that covers the legs with a knitted fabric that exerts a gradual compression force from the ankle portion toward the knee, and a low elasticity knitted fabric. The shape-retaining knitted fabric 12 that covers the instep, the heel knitted fabric 13 that covers the heel, the sole knitted fabric 15 that covers the sole with the highly elastic knitted fabric, and the toes. It is an elastic stocking having a toe knitted fabric portion 17 to be covered. The toe knitted fabric portion 17 has a toe bag portion 170 that covers the toe and a base band portion 171 that covers the base of the toe, and is open from the second toe to the fifth toe. ..

The compression knitted fabric portion 11 is knitted so that the highest compression force acts on the ankle portion and a gradual compression force acts from the ankle portion toward the knee or upper leg portion. Therefore, in general, the specifications or performance of compression stockings are displayed with the compressive force acting on the ankle, so once the compressive force acting on the ankle is determined, the leg is the technique used in the manufacture of normal stockings. It is organized in a similar way. The shape-retaining knitted fabric portion 12 is knitted with a low-stretch knitted fabric that covers the instep portion, and its shape and size are almost unchanged. The shape-retaining knitted fabric portion 12 can be knitted by tuck knitting.

The heel knitted fabric portion 13 is preferably one that is not slippery on both the foot and the floor, and it is preferable to use, for example, a thread made of polyester nanofibers. Here, the polyester nanofibers are such that the polymer forming the polymer is polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polylactic acid, polyester obtained by copolymerizing the third component, and the like, and has a single fiber diameter (of a single fiber). The diameter) is preferably 250 to 800 nm. The yarn made of the polyester nanofibers preferably has 2000 to 60,000 filaments of the polyester nanofibers and a total fineness (product of single fiber fineness and number of filaments) of 35 to 500 dtex. The knitted fabric made of such threads has a high grip force, and the elastic stockings 10 are in close contact with the heel portion and are not slippery, and are in close contact with the floor surface and are not slippery. Therefore, it is possible to prevent the person wearing the elastic stockings 10 from falling.

The heel knitted fabric portion 13 is knitted by half-turn reciprocating knitting with respect to the sole knitted fabric portion 15, which is considered to be a full rotation knitting. Then, as shown in FIG. 2, the heel knitted fabric portion 13 is provided with a heel bag portion 130 having an increased number of courses and an additional portion 131 extending from the heel bag portion 130 and having about half the number of courses of the heel bag portion 130. And leads to the sole knitted fabric part 15. Since the heel knitted fabric portion 13 has a gore line 21 in the direction of the top of the heel, which is generally provided in the heel bag portion 130 having an increased number of courses, the heel can be reliably wrapped. Then, an additional portion is provided across the gore line 22. As a result, regardless of the individual difference in wearing the elastic stockings, and regardless of the wearing state, the additional portion 131 surely adheres to the floor surface to prevent slipping, and it is possible to prevent the person wearing the elastic stockings 10 from tipping over. .. Further, as shown in FIG. 2, the heel knitted fabric portion 13 is preferably provided with a heel wire 135 in which a colored thread is woven into the outer peripheral edge thereof. As a result, the caregiver or the like can make the elderly or the like properly wear the elastic stockings, and can confirm the wearing state.

The sole knitted fabric portion 15 is knitted with a highly elastic knitted fabric as described above. In the highly elastic knitted fabric portion, the degree of expansion and contraction of the low elasticity knitted fabric is 30 to 100% in terms of elongation rate, whereas the elongation rate can be 80 to 200%. The elongation rate of the highly elastic knitted fabric can be 1.0 to 3.0 times the elongation rate of the low elasticity knitted fabric, preferably 1.5 to 2.5 times.

As described above, the toe knitted fabric portion 17 has a toe bag portion 170 that covers the mother toe and a base band portion 171 that covers the base of the toe, and is open from the second toe to the fifth toe. It will be. That is, although it is open from the second toe to the fifth toe, the mother toe is covered with the mother toe bag portion 170. As shown in FIG. 1, the basal band portion 171 includes an opening portion 175 and a foot extension portion 173 connected to the sole knitted fabric portion 15. Both the leg extension 173 and the opening 175 are knitted with a highly elastic knitted fabric. The leg extension section 173 is preferably composed of a first leg extension section 173a and a second leg extension section 173b, which have the same number of courses and are knitted by half-turn reciprocating knitting, respectively. The foot extension portion 173 covers the portion corresponding to the MP joint. Gore line 25 is included at the boundary between the first leg extension section 173a and the second leg extension section 173b.

Since this elastic stocking 10 is open from the 2nd toe to the 5th toe, it is easy to check whether the skin and nails of the toes are discolored and whether the elastic stocking 10 is used properly. You can check. Further, since the toe knitted fabric portion 17 is designed so that the mother toe is inserted into the mother toe bag portion 170, the toe knitted fabric portion 17 is knitted with a highly elastic knitted fabric and opens from the second toe to the fifth toe. Despite this, it is possible to prevent the opening 175 from turning over and the wearing position from shifting, and it is possible to maintain the proper wearing state of the elastic stocking 10. Further, in the elastic stockings 10, the foot extension portion 173 consists of two parts, the first foot extension portion 173a and the second foot extension portion 173b, so that the toe knitted fabric portion 17 is good for dorsiflexion of the sole of the foot. It has come to follow.

The opening 175 is knitted with a highly elastic knitted fabric and can cover the fifth toe (FIG. 3 (a)) or the second foot, as shown in FIG. The compression stockings 10 can be worn so that they are open from the toes to the fifth toe. Further, the present elastic stockings 10 can suppress coldness of the toes like elastic stockings having a known tubular shape and an opening at the tip portion.

Further, as described above, in the elastic stocking 10, the foot portion covers the instep portion with the shape-retaining knitted fabric portion 12, the heel knitted fabric portion 13 covers the heel portion, and the sole knitted fabric portion 15 and the foot. It is covered with the finger knitted fabric part 17. The shape-retaining knitted fabric portion 12 has low elasticity and the shape and size are almost the same, whereas the sole knitted fabric portion 15 and the toe knitted fabric portion 17 have high elasticity and are larger than the shape-retaining knitted fabric portion 12. It has a growth rate of 1.0 to 3.0 times. For this reason, the force that lifts the toes upwards acts. The toe knitted fabric portion 17 is provided with a foot extension portion 173, and the foot extension portion 173 is also provided with two portions, a first foot extension portion 173a and a second foot extension portion 173b. Therefore, the present elastic stockings 10 have an extension function of bending the legs dorsiflexion, and the muscle pump function can be enhanced by this extension function. Further, since the elastic stockings 10 have a shape-retaining knitted fabric portion 12 whose shape and size are almost the same, first, the shape-retaining knitted fabric portion 12 is put on the foot so as to match the instep portion. After that, it can be easily attached by covering the leg portion with the compressed knitted fabric portion 11 so as to pull it up. In addition, the pain of wearing elastic stockings can be suppressed. Therefore, elderly people and patients with joint disorders can wear it easily and with peace of mind.
