Description

Technical Field

[0001] This application relates to the field of medical assistive device technology, and in particular to an upper limb suspension device for fracture patients. Background Technology

[0002] Upper limb fractures are often accompanied by tissue damage, manifesting as local pain, swelling, and limited mobility. Clinically, forearm sling is necessary to elevate and immobilize the upper limb in a therapeutic position and maintain it in a functional position. Clinical studies have shown that immobilizing the affected limb at or above the level of the heart can promote venous return and arterial blood supply to the limb, and can significantly promote the reduction of limb swelling.

[0003] Currently, for bedridden patients with upper limb fractures, a pillowcase is typically attached to the IV stand. One corner of the pillowcase is used to create a funnel-shaped opening to support the upper and lower arm, allowing the upper limb to be elevated and reducing swelling. However, the upper limb often slips out of the opening during use. This is because when a bedridden patient's upper limb is raised, the upper arm is at an angle, and the bottom of the opening may be angled to contact the back of the upper arm. Over time, the arm can easily slip out of the opening. Secondly, with the arm pressed into the opening, the pillowcase is taut. If the patient moves, the pillowcase may loosen, allowing the upper limb to slip out of the opening, potentially preventing effective swelling reduction. Utility Model Content

[0004] The technical problem to be solved by this application is to provide an upper limb suspension device for fracture patients, which can stably fix the upper limb of fracture patients in an elevated position.

[0005] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0006] The upper limb suspension device for fracture patients includes a suspension pocket with an inlet at the front end. A restraint assembly is provided inside the lower part of the suspension pocket. The restraint assembly includes two upper arm restraint straps that are respectively connected to the left and right side walls inside the suspension pocket. A closing component is provided between the two upper arm restraint straps.

[0007] The top of the suspension bag is equipped with a traction rope;

[0008] The suspension bag has a fixed frame at the rear, and the traction rope is installed on the fixed frame.

[0009] Place the patient's forearm in the suspension bag, with the back of the upper arm in contact with the bottom of the suspension bag. Then, place two upper arm restraint straps on the front of the upper arm and connect the two upper arm restraint straps together through a closure assembly. Finally, suspend the suspension bag with a traction rope. The patient's upper limb is suspended and fixed by the upper arm restraint straps, and the upper limb will not slip out of the suspension bag.

[0010] To improve the breathability inside the suspension bag, in some embodiments, the rear end of the suspension bag is provided with several breathable mesh holes.

[0011] In order to enable the upper arm restraint strap to have the function of connecting and separating, in some embodiments, the closing component is preferably a zipper.

[0012] To improve the comfort of the upper limbs within the suspension pocket, in some embodiments, a padding layer is provided at the bottom of the suspension pocket.

[0013] To accommodate patients of different body types, in some embodiments, the bottom of the suspension bag is provided with an adjustment component, which includes a buckle. The left and right ends of the buckle are respectively connected to a first strap and a second strap, and the first strap and the second strap are respectively connected to the left and right sides of the bottom of the suspension bag.

[0014] Compared with the prior art, this application achieves at least the following beneficial effects: the suspension device is equipped with an upper arm restraint strap in the suspension pocket, which can restrain the upper arm during use and prevent the upper limb from slipping out of the suspension pocket due to the sloping surface of the suspension pocket; even if the patient turns over and moves the upper limb, the upper limb will not fall out of the suspension pocket due to the fixed restraint of the upper arm restraint strap, so that the upper limb is stably placed in the suspension pocket to reduce swelling.

[0023] The present application will now be described in detail with reference to exemplary embodiments shown in the accompanying drawings. However, it should be understood that the present application may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided herein to make the disclosure of the present application more complete and to fully convey the concept of the present application to those skilled in the art.

[0024] In the description of this application, it should be understood that the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limiting the scope of protection of this application.

[0025] To address the shortcomings of existing technologies that may not stably immobilize the upper limb of fracture patients in an elevated position, the inventors, after careful analysis, discovered that the main reason for this problem lies in the fact that current techniques for elevating the upper limb of patients with forearm fractures are primarily designed to prevent swelling, as the forearm is essentially perpendicular to the bed and the patient is lying down. Figure 1 As shown, a pillowcase was used locally. Figure 1 The white, vertically slanted section is a pillowcase; the area to the lower left of the needle corresponds to the patient's fractured upper limb. Tuck one corner of the pillowcase into the opposite corner to form a pocket-shaped opening for holding the upper and lower arm. The top of the pillowcase is then attached to the IV stand. When the bedridden patient raises their upper limb, the upper arm is at an angle, and the bottom of the pocket opening is pressed against the back of the upper arm, creating a sensation similar to... Figure 1 As shown in the diagram, the slope is such that the patient may move their body or upper limbs while lying in bed. Over time, the arm can easily slip out of the bag opening. Secondly, when the arm is pressed into the bag opening, the entire pillowcase is in a taut state. At this time, due to the displacement of the patient's upper torso, the entire pillowcase will... Figure 1Because of its tilted shape, if the patient moves their body or upper limbs, the pillowcase may loosen and easily swing back, allowing the upper limb to easily slip out of the pillowcase's opening, potentially hindering swelling reduction. Based on this analysis, the inventors improved the pillowcase's structure.

[0026] like Figure 2-6 As shown, in at least one embodiment of the upper limb suspension device for fracture patients in this application, a suspension bag 1 for placing the patient's upper limb is included. The suspension bag 1 can be made by using a pillowcase, which is vertically arranged and cut into two parts in the middle. One part of the pillowcase is inserted into the other part and connected by sewing to form a suspension bag 1 with a vertical insertion entrance at the front end. The lower part of the suspension bag 1 is provided with a restraint component to prevent the upper arm from slipping out. The restraint component includes two upper arm restraint straps 8 that are respectively sewn to the left and right side walls inside the suspension bag 1. The upper arm restraint straps 8 have a certain width and can be made of materials such as canvas or elastic Lycra. A closing member 9 is provided between the two upper arm restraint straps 8. The two upper arm restraint straps 8 are connected through the closing member 9. After connection, they form a cylindrical arm sleeve structure with the bottom of the suspension bag 1.

[0027] The top of the suspension bag 1 has a horizontal through hole, and a traction rope 5 is installed in the through hole. The traction rope 5 is tied to the suspension bag 1 by a slip knot or a knot. A fixing frame is provided on the rear side of the suspension bag 1, and the traction rope 5 is installed on the fixing frame. Specifically, the fixing frame includes a vertical metal main rod 4. A fixing seat is installed at the bottom of the main rod 4, and the top is bent forward to form a support rod 3. A first reel seat 2 is welded to the right side of the support rod 3, and a second reel seat 15 is welded to the right side of the upper middle part of the main rod. After the traction rope 5 passes through the groove of the first reel seat 2, it is fixed and wound around the groove of the second reel seat 15. By rotating the second reel seat 15, the suspension bag 1 can be raised and lowered by extending and retracting the traction rope 5.

[0028] Considering that the suspension pocket 1, made of a pillowcase, has a double-layer structure, the breathability is poor when the upper limbs are placed inside the suspension pocket 1. Therefore, several breathable mesh holes are opened at the rear end of the suspension pocket 1 to improve breathability.

[0029] The closure component 9 should preferably use a zipper structure. The patient's upper limb is placed inside the suspension bag 1, and the two upper arm restraint straps 8 are laid on the front of the upper arm. By closing the zipper, the upper arm restraint straps 8 and the bottom of the suspension bag 1 form a cylindrical arm sleeve structure. The patient's upper arm is fixedly fitted between the suspension bag 1 and the upper arm restraint straps 8. After the swelling subsides, the upper arm restraint straps 8 can be untied simply by pulling open the zipper. Therefore, using a zipper as the closure component 9 allows the upper arm restraint straps 8 to be quickly connected or separated.

[0030] The bottom of the suspension pocket 1 has a padding layer 7. The padding layer 7 and the bottom of the suspension pocket 1 can be connected by Velcro. That is, the female Velcro patch is sewn to the bottom of the suspension pocket 1, and the female Velcro patch is glued to the bottom of the padding layer 7. When the padding layer 7 is soiled or worn, it can be quickly replaced. The padding layer 7 has a rectangular plate structure and can be made of materials such as sponge, fabric, or silicone.

[0031] The bottom of the suspension pouch 1 is equipped with an adjustment component. The function of the adjustment component is to reduce the diameter of the arm sleeve structure when the upper arm size of the patient using this device is smaller than the diameter of the arm sleeve structure formed by the upper arm restraint strap 8 and the bottom of the suspension pouch 1. The adjustment component includes a quick-release buckle, which is divided into a female buckle 10 and a male buckle 11. The left end of the female buckle 10 is connected to a first strap 18, and the right end of the male buckle 11 is connected to a second strap 12. (The connection method between the female buckle 10, the male buckle 11, the first strap 18, and the second strap 12 can adjust the length of the first strap 18 and the second strap 12. It is roughly as follows: the strap is passed through the fixing ring on the buckle, folded back and sewn or fixed with a rivet. When moving the strap, the free end of the strap is pulled to adjust to the required length. This connection method is existing technology and is only explained here without further elaboration.) The first strap 18 is sewn to the left side of the bottom of the suspension pouch 1, and the second strap 12 is sewn to the right side of the bottom of the suspension pouch 1. If the patient's upper arm is small, the length of the first strap 18 and the second strap 12 on the female buckle 10 and the male buckle 11 can be shortened. Then, the female buckle 10 and the male buckle 11 can be inserted together, and the bottom of the suspension pocket 1 will be narrowed, thereby reducing the diameter of the arm sleeve structure.

[0032] On the side wall at the front end of the suspension bag 1, there are coaxially distributed through holes, and a tension rope 13 is installed inside the coaxial through holes, such as... Figure 2 and Figure 6 As shown, a spherical spring buckle 14 is fitted on the right side of the suspension pocket 1 on the elastic cord 13. A circular limiting piece 131 made of plastic is heat-fused to the left end of the elastic cord 13 (to prevent the elastic cord 13 from coming out of the through hole; a knot can also be tied at the left end of the elastic cord 13). The function of the elastic cord 13 is to narrow the entrance of the suspension pocket 1 and restrain the forearm from excessively bending away from the suspension pocket 1. Specifically, after pressing the spring buckle 14, the spring buckle 14 moves to the left and pulls the elastic cord 13 to the right, causing the left and right sides of the front end of the suspension pocket 1 to close towards the center, narrowing the entrance. When the spring buckle 14 is released, it locks onto the elastic cord 13, restricting the entrance from opening.

[0033] In addition, an angle iron 16 is welded to the right side of the main rod 4, below the second reel seat 15. The right end of the angle iron 16 is bent upwards, and a screw hole is opened on the right end face of the bent angle iron 16. A wing bolt 17 is screwed into the screw hole. A square groove 151 is opened on the right end of the second reel seat 15. This device can be equipped with a Z-shaped adjustment handle 6. The left end of the adjustment handle 6 is connected to a protrusion that matches the square groove 151. By inserting the protrusion of the adjustment handle 6 into the square groove 151, the rotation of the second reel seat 15 can be controlled, thereby extending and retracting the traction rope 5 and adjusting the height of the suspension bag 1. After adjusting the height of the suspension bag 1, tighten the wing bolt 17 so that its threaded section presses tightly against the right side of the second reel seat 15, restricting the rotation of the second reel seat 15 and preventing the suspension bag 1 from falling.

[0034] When using the device, first move the fixation frame to the side of the bed, then extend the traction rope 5 through the second thread wheel seat 15, lower the suspension bag 1, and then place the patient's fractured upper limb into the suspension bag 1 through the insertion port. Connect the two upper arm fixation straps together through the closing component 9. At this time, the patient's upper arm is fixed. Then, by rotating the second thread wheel seat 15, shorten the traction rope 5 and raise the suspension bag 1 to a suitable height. Use the butterfly bolt 17 to lock the second thread wheel seat 15 to restrict its rotation. Finally, narrow the insertion port through the tension rope 13. At this time, the patient's fractured upper limb is stably fixed in a high position to reduce swelling.

[0035] It should be understood that all the above embodiments are exemplary and not restrictive. Various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of this application should be within the protection scope of this application.
