Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a hard skeleton limb sleeve. Background Art

[0002] Clinically, applying periodic pressure to the limbs can promote blood circulation and accelerate the return of tissue fluid, thereby relieving symptoms such as edema, pain, soreness, heaviness of the limbs, and intermittent claudication caused by venous edema of the limbs and ischemia of the lower limb arteries. The overall structure of the existing pressure limb sleeve is soft. The outer layer material is generally made of nylon or non-woven TPU (thermoplastic polyurethane elastomer rubber) material through high-frequency heat bonding, and then processed into a double-layer structure that conforms to the shape of the limb, and the interior is divided into several chambers. The air pressure therapy device connected to the sleeve can output air with a certain pressure. After the air enters the separated chamber through the air nozzle on the sleeve, the outer shape of the chamber expands, thereby exerting a certain uniform pressure on the patient's limbs.

[0003] However, the volume of the limb sleeve made of soft materials will expand a lot during the inflation process, which requires enough gas to form a sufficiently stable pressure. In order to fill enough gas in the shortest possible time, the flow output of the air pump in the air pressure therapy device needs to be very large; and the limb sleeve made of soft materials is generally fastened to form a tube-shaped sleeve wrapped around the outside of the limb through zippers, nylon hooks, etc., and some sleeves are directly processed into a fixed-size tube, which brings the problem of inconvenience in putting on and taking off. Summary of the invention

[0004] The purpose of the present invention is to provide a hard skeleton limb sleeve, which can limit the expansion space of the limb sleeve, so that the amount of gas required for the sleeve to reach the expected pressure is reduced, so that the host of the air pressure therapy device can use an air pump with a smaller flow rate, thereby reducing the volume of the product and reducing costs.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0011] Optionally, the first frame includes a third frame and a fourth frame connected by a second hinge;

[0012] Two opposite stop protrusions are provided on both sides of the connection between the third frame and the fourth frame.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The purpose of the present invention is to provide a hard skeleton limb sleeve, which can limit the expansion space of the limb sleeve, so that the amount of gas required for the sleeve to reach the expected pressure is reduced, so that the host of the air pressure therapy device can use an air pump with a smaller flow rate, thereby reducing the volume of the product and reducing costs.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Figure 1 FIG. 1 is a schematic diagram of a rigid skeleton limb sleeve structure according to an embodiment of the present invention; Figure 1 As shown, a hard skeleton limb sleeve includes a first skeleton, a second skeleton, an airbag 5, an electric screw 7, an airbag vent 8 and a first hinge 9;

[0032] Among them, the first frame and the second frame are hard materials such as engineering plastics and aluminum alloys; one side of the first frame and one side of the second frame are connected by a first hinge 9 to form a cylindrical structure; a locking device is provided at the connection between the first frame and the second frame, which is used to fix the open or closed state of the first frame and the second frame, and the locking device can be manual or electric locking; preferably, the locking device is an electric screw 7, and a first protrusion and a second protrusion are respectively arranged on both sides of the connection between the first frame and the second frame, and there are threaded holes on the first protrusion and the second protrusion, and the motor of the electric screw 7 is fixed on the first protrusion, and the electric screw 7 is fixed to the first frame and the second frame through the threaded holes of the first protrusion and the second protrusion, and the cylindrical structure can be closed or opened by controlling the electric screw to move forward or backward.

[0033] There are multiple airbag vents 8, which are connected to the airbag 5 made of elastic material and are used to inflate or deflate the airbag 5; the airbag 5 is attached to the inner side of the tubular structure by nylon hook and loop or adhesive to apply pressure to the limb.

[0034] Specifically, the first frame includes a third frame 1 and a fourth frame 2 connected by a second hinge, and opposite stop protrusions 6 are provided on both sides of the connection between the third frame 1 and the fourth frame 2. The stop protrusions have a plane 6. When the third frame 1 and the fourth frame 2 are opened, the planes of the two opposite stop protrusions 6 are in contact, which is used to limit the excessive opening of the third frame 1 and the fourth frame 2.

[0035] The second frame includes a fifth frame 3 and a sixth frame 4 connected by a third hinge;

[0036] Two opposite stop protrusions are provided on both sides of the connection between the fifth frame 3 and the sixth frame 4. The protrusions have a plane. When the fifth frame 3 and the sixth frame 4 are opened, the planes of the two opposite protrusions are in contact, which is used to limit the excessive opening of the fifth frame and the sixth frame.

[0037] When the hard skeleton limb sleeve is in use, the electric screw 7 is used to open the fourth skeleton 2 and the sixth skeleton 4, and the limb sleeve can be easily worn on the user's limb, and then the electric screw 7 is used to close the fourth skeleton 2 and the sixth skeleton 4. At this time, the third skeleton 1 and the fifth skeleton 3 will not be excessively opened due to the limiting effect of the stop protrusion. At this time, the airbag 5 is wrapped outside the user's limb, and the air pressure therapy device can inflate or deflate the internal airbag 5 through the airbag vent 8 to achieve a predetermined therapeutic effect. The opening and closing states of the hard skeleton limb sleeve are shown in FIG. Figure 2 and Figure 3 shown.

[0038] After the use of the hard skeleton limb sleeve, the entire hard skeleton limb sleeve can be folded and stored to reduce the storage space of the sleeve. The storage form diagram is shown in FIG. Figure 4 shown.

[0039] The present invention also discloses the following technical effects:

[0040] 1. The present invention uses hard engineering plastics, aluminum alloy and other materials to make the external frame of the limb sleeve, which limits the expansion space of the limb sleeve, greatly reducing the amount of gas required for the sleeve to reach the expected pressure, so that the host of the air pressure therapy device can use an air pump with a smaller flow rate, reducing the volume of the product, energy consumption, and cost.

[0041] 2. The present invention adopts a hard frame as the outer frame of the sleeve, which limits the expansion space of the limb sleeve, which is equivalent to reducing the internal force of the sleeve and reducing the requirements of the sleeve itself on materials and heat-sealing process.

[0042] 3. The present invention adopts a hard frame to directly fix the shape of the sleeve, so that the sleeve no longer needs to be closed by using zippers, nylon hooks, etc., thus saving the process flow.

[0043] 4. The present invention can be opened and closed. When opened, the patient's limbs can be easily inserted, and when closed, the required state of wrapping the patient's limbs can be achieved. The locking device of the electric screw provides additional effective support to prevent the opening and closing structure from opening under stress.
