Description

Limb treatment machine

Technical field

The invention relates to the technical field of medical treatment equipment, in particular to the treatment of arthritis and tenosynovitis and sprained parts of small joints such as knees, fingers, toes, wrists, elbows and ankles, and at the same time, because of blood, tissue fluid, lymph Diseases caused by fluid circulation disorders such as diabetic foot, gangrene of the extremities, vasculitis, edema and other diseases have unique therapeutic or health effects.

Background technique

Diabetic gangrene is usually caused by vascular damage caused by diabetes, mainly caused by atherosclerosis of the large and middle arteries. In peripheral blood vessels, often lower extremity arterial lesions. Due to the persistence of diabetes, it can stimulate and accelerate the formation of atherosclerotic plaque, leading to stenosis or occlusion of limb arteries, resulting in severely insufficient blood supply to the extremities and gangrene, and due to the decreased utilization of sugar in diabetic patients, severe limb supply Insufficient oxygen supply, and the occurrence of blood circulation disorders further aggravate the degree of extremity. Because the skin and soft tissues of the ulcer are easily infected by bacteria, and most of them are resistant, common treatments require the use of multiple antibiotics, which are difficult to heal and cause great pain to the patient, which not only reduces the patient's quality of life but also increases the weight. The economic burden.

Diabetic gangrene is mostly found in middle-aged and elderly people; male to female, the ratio of male to female is 3:2; the average duration of diabetes is about 10 years, the lower extremities of gangrene are more common, accounting for 92.5%, the upper limbs are rare, accounting for 7.5%; Side incidence accounts for about 80%, bilateral onset is about 20%; toe and sole are common at the same time, accounting for 77.5%; toe and calf at the same time gangrene accounted for 5%, only calf gangrene accounted for 5%; toe Or finger disease accounted for 12.5%.

Patients with impaired limb blood circulation, such as diabetic patients, are treated with positive and negative pneumatic limb treatment equipment. At present, because there are already patent applications for positive and negative pneumatic limb treatment equipment, equipment and limb sealing are the key technologies for the success of this product, especially for medical or health care applications, which are generally under positive and negative pressure of 20KPa. Large, dense The sealing requirements are very strict. A little leak will make it difficult to reach normal working pressure. It is also because of difficulties, so there is no successful solution to the sealing scheme. Therefore, the equipment has not appeared to benefit the patients and the general public.

The airbag seal is a relatively easy way to seal the human limb and the negative pressure or positive pressure generating device. However, the inventors have found that the airbag seal is difficult to implement on the limb seal, and the control method is complicated and costly. Although the sealing method of the sealing sleeve is feasible and effective, it is not easy to disinfect, and it is easy to form cross infection, which is not suitable for use in hospitals and other places. At present, there is no disposable sealing method suitable for pushing to the medical market.

In addition, in use, because some patients' legs or arms are long and short, patients with short limbs may not be able to reach the bottom of the treatment cavity during treatment, assuming that the cavity opening forms a seal with the thigh or upper limb, at the negative Under pressure, assuming that the cavity is fixed, the limb at the seal will have an inward sliding thrust due to the negative pressure. If the human body controls the leg or arm without sliding it into the cavity, then at the leg or arm. Subject to friction (friction between the sealing material). In the negative pressure state, if the human leg or arm remains stationary, then when the weight is not heavy enough, because the friction between the support surface and the support surface will be limited, the cavity has the upper end of the thigh or the arm (near heart) End) The tendency to slide. The negative pressure in the treatment cavity causes the treatment cavity to move relative to the limb in opposite directions. When the cavity contacts the limb, a large pressing force is formed on the limb, and the blood vessel narrows the blood vessel due to the pressing force. Poor circulation, contrary to the principle of treatment of this type of equipment, runs counter to the other, seriously affecting the treatment effect.

Summary of the invention

In view of the above defects of the prior art and equipment, the present invention provides a limb treatment machine capable of reducing the pain of a patient, improving the curative effect, and reducing the cost of treatment.

The object of the present invention is achieved by a limb treatment machine comprising one or two treatment chambers, connected to a side wall of the treatment chamber for an air pressure generating system for pumping or inflating the chamber; The treatment chambers are composed of two shells which are matched with each other, one side of the two shells is connected by a hinge, the other side is connected by a fastener, and the sealing strips are respectively arranged on the joint side seams of the two shells; A limb outlet is provided on the treatment cavity, and a sealing assembly is arranged at the limb entrance and exit.

The invention has the following distinct advantages:

1. The invention proposes a design scheme for a therapeutic machine capable of reducing the pain of a user, improving the curative effect, reducing the cost of treatment, and being portable and capable of rehabilitating the physical rehabilitation and physical recovery of the family.

2. Since the treatment cavity of the present invention is of a split design, the limb entrance and exit can be opened, and the limb (such as the leg or the arm) can be simply placed into the treatment cavity instead of extending into the treatment cavity as before, and the user's limb is removed. The pain of unsuitable activities also reduces the difficulty of disinfection in medical facilities.

The sealing assembly of the present invention comprises a flexible sealing material having a suitable sealing material wound around the limb opening and exiting body and the limb. The flexible sealing material has one end wound around the limb entrance and exit, and the other end is wound around the limb, and the gap between the limb entrance and exit and the limb is covered. The flexible sealing material is sealed such that the cavity opening of the limb treatment device is isolated from the atmosphere. After repeated practice and exploration, the winding flexible sealing material (band shape) is used to seal the gap between the cavity and the limb. The experiment proves that the sealing effect is good and the operation is convenient, which provides a simple way for the positive pressure or negative pressure limb treatment equipment to enter the market. Reliable technical guarantee. For a certain negative pressure (-20KPa), if the limb extends into the cavity, if the gap between the limb and the cavity opening is small or the area is small, the flexible material covering the area between the gaps will have a certain elastic sealing material. With relatively small pressure, the pressure on the sealing material of the gap portion is small, and the pressure is ultimately shared by the sealing material of the cavity flange mouth and the surface of the limb, so if the pressure is small, then the direct contact with the human limb If the tension of the sealing material of the leg is relatively small, if the pulling force is less than the maximum static friction that the sealing material can withstand in contact with the human body, due to negative When the pressure occurs, the sealing material will be tightly attached to the limbs, and it will not need to be affixed to the sealing material to increase the friction, which makes the use relatively simple, convenient and reliable, so the extensive use of the limb treatment equipment will There are no more obstacles. On the contrary, for a certain negative pressure, if the gap between the limb and the cavity opening is large, that is, if the gap is large, the pressure of the sealing material of the gap portion is large, and the pressure is large, and the pressure is large. The sealing material pulling force of the leg-contacting contact portion may exceed the maximum static friction between the limb and the sealing material, and a strap or the like is required to increase the pressure to increase the friction without disengaging the sealing material from the limb.

The flexible sealing material of the present invention has a buckle or a strap for tightening, the flexible sealing material is in the form of a belt, and the flexible sealing material is PE, PVDC, latex, nitrile rubber, butyl rubber, and chloroprene. Rubber, one of the PVC.

The sealing assembly of the present invention comprises a cone-shaped flexible sealing sleeve made of a gas-impermeable flexible polymer material and sleeved on a limb, the large end of the flexible sealing sleeve being connected with the limb inlet and outlet, in the flexible sealing sleeve At least one first opening is disposed on the side, the first opening is disposed along the axial direction of the flexible sealing sleeve, one end of the first opening extends to the small end of the flexible sealing sleeve, and the flexible sealing sleeve on both sides of the first opening is sealed by a moisture sealing zipper In order to facilitate the moisture-sealed zipper pull-down opening to expand the limbs in and out. Due to the use of the airtight zipper, it is possible to select a gas-tight sealing material with a good elastic force to form a sealing sleeve, and reduce the diameter of the opening of one end which is in contact with the limb, which is smaller than the diameter of the limb, and can be utilized after pulling the zipper. The elastic force of the sealing sleeve itself directly adheres to the limb to form a good seal, which greatly reduces the operation difficulty. This sealing technology will enable the limb treatment machine to go to the market for the benefit of the people. The treatment cavity can be designed as a vertical type to facilitate the patient to sit on the treatment; the treatment cavity can also be designed as a horizontal type to facilitate the treatment of the affected limb, so that the patient can lie down to increase comfort.

In order to further improve the sealing effect, the sealing assembly further includes a curved sealing block disposed at a gap between the limb entrance and the limb, and the arc sealing block is movable Cover or curved filler block. By increasing the movable cover or the filling block to reduce the gap area, thereby reducing the pressure of the sealing material at the gap formed by the external atmosphere and the internal pressure difference, since the pressure is proportional to the area, by reducing the gap area The pressure on the sealing material at the gap can be reduced, so that the sealing can be sealed with a common strength, the room for selection is greatly increased, and since the cover or the filling block is movable, it is very convenient to operate.

Each of the treatment chambers of the present invention has a circular cross section, and both of the housings are semi-circular, and the two housings cooperate to form a circular shape; the limb opening and closing openings are composed of two semicircular openings, two halves. The circular openings cooperate to form a circle. The treatment cavity is circular, including upper and lower parts and cooperate with each other to facilitate the insertion of the limbs. After the limbs are placed, the upper and lower covers are closed, and the gap between the limbs and the openings is better controlled to facilitate the sealing and sealing of the sealing members, thereby ensuring the sealing effect. Thereby ensuring the therapeutic effect.

The air pressure generating system of the present invention has a set of two treatment chambers, and the air pressure generating system is in communication with one of the treatment chambers, and the two treatment chambers are connected by a push-in hose. When the legs are treated, the control system only needs one set. The structure of the two treatment chambers is the same. The split type is the upper and lower parts. After opening the upper cover, they are placed in two separate treatment chambers. The plug-in hose connects the gas. Because there is a hose connection between the two treatment chambers, the air pressure on both sides changes exactly the same, which makes it easier to treat the legs at the same time, and because it is a split type upper and lower structure, operation Convenience. If you are treating a single leg, you only need to use one treatment cavity.

The air pressure generating system of the present invention includes a controller and a vacuum pump coupled to the controller, the other end of the vacuum pump being coupled to the treatment chamber via a conduit. The other end of the vacuum pump can be directly connected to the treatment cavity, or can be connected to the treatment cavity through a pipe to facilitate production and use.

The limb access opening on each of the treatment chambers of the present invention is a pair of second openings, the pair of second openings being comprised of an opening into which the limb extends and an opening through which the limb extends. when using it A limb (such as a leg or an arm) may extend from one end to the other and form a seal between the opening at both ends and the limb.

Further, a plurality of radial bosses are respectively fixedly connected to the inner side of the single-opening treatment cavity, and a plurality of radial bosses are disposed in the longitudinal direction of the casing, and a gap forming limit is formed between the adjacent two radial bosses. The positioning slot is arranged symmetrically with the limiting slot in the other housing; the same adjusting plate is arranged in the two housings, and the adjusting plate is inserted in a pair of limiting slots arranged symmetrically. After the radial bosses on the two mating housings are assembled to form a unitary body, the radial bosses serve to limit the adjustment plates. The adjustment plate can be determined according to the length of the patient's limb (such as the leg). In the pair of limit slots, if the patient's leg is long, the adjustment plate is located at the end away from the limb entrance and exit. If the patient's leg is short, the adjustment plate is to the limb entrance and exit. The direction is adjusted so that the foot of the patient, whether the leg is long or the leg is short, always abuts the adjustment plate. When there is negative pressure in the treatment cavity, since the treatment cavity moves to the thigh without the adjustment plate, the improved hind foot always abuts against the adjustment plate to prevent the treatment cavity from moving to the thigh. The treatment cavity and the limb will not cause relative displacement due to the restriction of the adjustment plate, and the sealing effect is ensured to ensure the therapeutic effect.
