Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an arm abduction device. Background Art

[0002] Rotator cuff fracture is a common injury in trauma orthopedics. For such patients, preoperative and postoperative care and recovery are particularly important. At present, in order to ensure that the fracture site remains in a functional position and relieve the patient's pain, doctors usually recommend that patients wear an abduction bag. The main function of this abduction bag is to wrap the patient's forearm to keep the arm in a specific position, while ensuring that the joint is relaxed and reducing unnecessary movement and pressure.

[0003] However, existing abduction bag designs often have some shortcomings. First, due to the material and design, many abduction bags have poor breathability. Long-term wearing can cause the patient's skin to feel stuffy and may even cause skin problems such as eczema or dermatitis, causing additional pain to the patient.

[0004] Secondly, in order to ensure that the arm has a certain abduction angle, a fixed pillow is usually set between the patient's forearm and body. However, most of the fixed pillows on the market are fixed in size and cannot be flexibly adjusted according to individual differences such as the patient's height and weight. This means that for patients of different body shapes, the fixed pillow may not provide the best support angle, thus affecting the patient's treatment effect and recovery speed. Utility Model Content

[0005] In view of this, the purpose of the present invention is to overcome the deficiencies in the related art. The present invention provides an arm abduction device.

[0006] The utility model provides the following technical solutions:

[0037] Example 1

[0038] like Figure 1 As shown, this embodiment provides an arm abduction device for keeping the patient's shoulder joint in an abducted position, including an abduction bag 100, a hanging assembly 200, a fixing pillow 300, and a ventilation assembly 400.

[0039] The abduction bag 100 is used to wrap the patient's forearm; the hanging assembly 200 is arranged on the abduction bag 100, and the hanging assembly 200 is used to hang the abduction bag 100 on the patient; the fixing pillow 300 is arranged on the end surface of the abduction bag 100 close to the patient's body; the ventilation assembly 400 is arranged on the abduction bag 100, and is used to ventilate the patient's forearm in the abduction bag 100.

[0040] The arm abduction device provided in this embodiment is intended to help patients maintain an arm abduction position more easily and comfortably. During use, first, we will gently wrap the abduction bag 100 around the patient's forearm to ensure that it fits the patient's skin tightly and comfortably. Then, through the hanging assembly 200, we will hang the abduction bag 100 on the front side of the patient's body, so that the patient's forearm can be suspended, thereby releasing the load-bearing pressure on the patient's shoulder and arm.

[0041] At this time, we further install a fixing pillow 300 between the abduction bag 100 and the patient's body. This fixing pillow 300 not only provides stable support for the patient's forearm, but also ensures that the patient's forearm and body can maintain a suitable angle. This design allows the patient to maintain the arm abduction position for a long time and stably, greatly reducing the patient's pain and avoiding secondary injury.

[0042] Furthermore, by providing the ventilation component 400, when the patient uses the device, he only needs to activate the ventilation component 400 to achieve continuous ventilation between the abduction bag 100 and the patient's forearm. This design not only effectively avoids the feeling of suffocation of the patient's skin, but also reduces the probability of related complications caused by long-term airtightness, thereby alleviating the patient's pain and improving the overall treatment effect.

[0043] In general, the arm abduction device provided in this embodiment brings great convenience and comfort to patients through its unique design and humanized functions.

[0044] In some embodiments, the side of the abduction bag 100 is provided with an opening, and the two side edges of the opening of the abduction bag 100 are connected by a connector 110, and the connector 110 can adjust the distance between the two side edges of the opening of the abduction bag 100; when patients of different body sizes use this embodiment, by using the connector 110 to adjust the distance between the two side edges of the opening of the abduction bag 100, the abduction bag 100 can always provide the patient's forearm with a wrapping experience of appropriate tightness and better fit, thereby improving the patient's usage experience; specifically, the connector 110 can be made of Velcro, which is convenient and efficient to adjust.

[0045] In some embodiments, an elbow stopper 120 is provided at one end of the abduction bag 100, so that when the abduction bag 100 is wrapped around the outside of the patient's forearm, the elbow stopper 120 surrounds the joint between the patient's forearm and upper arm, which can effectively prevent the patient's forearm from falling out of the abduction bag 100, thereby ensuring the reliability of use of this embodiment.

[0046] In some embodiments, the sling assembly 200 includes a front sling 210 and a rear sling 220, wherein the front sling 210 is connected to the end of the abduction bag 100 away from the elbow stop 120, and the rear sling 220 is connected to the end of the abduction bag 100 close to the elbow stop 120, and the front sling 210 and the rear sling 220 are connected by an upper sling 230; the upper sling 230 is hung obliquely on the shoulder of the patient and the opposite side of the forearm that needs to be abducted, so that the shoulder bears the weight of the patient's forearm , making the suspension of the patient's forearm more stable and reliable; further, by connecting the front sling 210 to the end of the abduction bag 100 away from the elbow stop 120, when the abduction bag 100 is hoisted, the end of the patient's forearm away from the elbow stop 120 is tilted upward, and the elbow stop 120 supports the patient's elbow joint and the front sling 210 pulls the patient's forearm upward, thereby further reducing the probability of the patient's forearm detaching from the abduction bag 100, thereby ensuring the reliability of use of this embodiment.

[0047] In some embodiments, the upper sling 230 includes a first shoulder strap 231 and a second shoulder strap 232. By placing the first shoulder strap 231 on the patient's shoulder and passing the second shoulder strap 232 through the patient's armpit, the upper sling 230 can be effectively prevented from slipping off the patient's shoulder, thereby ensuring the reliability of the sling assembly 200 for slinging the abduction bag 100. Of course, in other embodiments of the present invention, the upper sling 230 can also be configured as a double shoulder strap structure arranged in parallel to reduce the probability of the upper sling 230 slipping off the patient's shoulder during use.

[0048] In some embodiments, the fixed pillow 300 is a support airbag, and an inflation port 310 is provided on the support airbag. The inflation port 310 is used for external inflation equipment, and the fixed pillow 300 is connected to the side of the abduction bag 100 through Velcro; by setting the fixed pillow 300 as a support airbag, it is convenient for medical staff to connect the inflation port 310 to the inflation equipment to inflate the fixed pillow 300 according to the patient's arm abduction angle requirements, and inflate the fixed pillow 300 to the required volume, and then provide support for the patient's forearm. The adjustment is convenient, efficient and accurate, which is convenient to improve the treatment efficiency of the patient, and When the patient's forearm abduction angle needs to be adjusted, there is no need to replace the fixing pillow 300, and it can be completed without the patient's forearm making large movements, which effectively reduces the patient's pain; and the fixing pillow 300 is connected to the side of the abduction bag 100 by Velcro, which is convenient for medical staff to make relatively fine adjustments to the relative positions of the fixing pillow 300 and the abduction bag 100 when treating patients of different body shapes, so as to ensure the best treatment effect for the patients; of course, in other embodiments of the utility model, the fixing pillow 300 can also be connected to the abduction bag 100 by setting other structures.

[0049] In some embodiments, the end surface of the fixing pillow 300 close to the outreach bag 100 is provided with a groove 320 corresponding to the shape of the outreach bag 100, so as to increase the bonding area between the fixing pillow 300 and the outreach bag 100 and ensure the connection reliability between the fixing pillow 300 and the outreach bag 100.

[0050] In some embodiments, a waist belt 330 is provided at the end face of the fixing pillow 300 away from the abduction bag 100 to further limit the position of the fixing pillow 300, thereby preventing the fixing pillow 300 from shifting or falling off during the patient's activities, and ensuring the normal use of the fixing pillow 300.

[0051] In some embodiments, the waist belt 330 is connected to the fixed pillow 300 via Velcro, which facilitates quick and correct installation of the waist belt 330 and the fixed pillow 300; of course, in other embodiments of the utility model, the waist belt 330 can also be connected and installed with the fixed pillow 300 via other structures.

[0052] In some embodiments, the front sling 210, the rear sling 220, the upper sling 230 and the waist belt 330 of the sling assembly 200 are all made of nylon material. Nylon material has the advantages of high strength, wear resistance, tear resistance, durability, and lightness and portability. Of course, in other embodiments of the present invention, the above-mentioned structures can also be made of other materials.

[0053] In some embodiments, the front strap 210, the rear strap 220, the upper strap 230 and the waist belt 330 of the lifting assembly 200 are provided with sponge pads on the end surfaces close to the patient's body. By providing the sponge pads, it is possible to effectively avoid friction between the above-mentioned components and the patient's body when they come into contact with the patient's body, thereby preventing damage to the patient's body, while also ensuring the patient's comfort.

[0054] like Figure 2 As shown, in some embodiments, the ventilation component 400 includes a ventilation interlayer 410 and an air supply device 420. The ventilation interlayer 410 is arranged on the inner side wall of the outreach bag 100. The ventilation interlayer 410 is evenly distributed with air ducts 411. The air supply device 420 is connected to one end of each of the air ducts 411 through an air supply pipe 421. The side wall of the air duct 411 is provided with air holes that are connected to the inner side of the outreach bag 100. The air holes are provided in multiple and evenly distributed on the air ducts. By starting the air supply device 420, the air supply device 420 can generate airflow, and the airflow can pass through the air supply pipe 421 and enter the air duct 411. When the airflow passes through the air duct 411, it can exchange airflow with the air in the abduction bag 100 through the air vents, thereby exchanging air between the abduction bag 100 and the patient's forearm, thereby avoiding the problem of stuffiness on the skin of the patient's forearm and improving the safety and comfort of the patient's use of this embodiment. Specifically, the air supply device 420 uses a small air pump, a small fan, etc. to avoid burdening the patient's body.

[0055] In some embodiments, the ventilation assembly 400 also includes a diverter seat 430, and the diverter seat 430 is arranged at one end of the outreach bag 100. A diverter cavity is provided in the diverter seat 430, and the diverter cavity is simultaneously connected to one end of each of the air ducts 411. The air supply device 420 is connected to the diverter cavity through the air supply pipe 421. After the airflow delivered by the air supply device 420 enters the diverter cavity through the air supply pipe 421, the airflow will evenly enter each of the air ducts 411 through the diverter cavity, so as to ensure the uniformity of the airflow delivered by the air supply device 420 to each of the air ducts 411, thereby further improving the ventilation effect of the outreach bag 100.

[0056] Specifically, a plurality of guide channels corresponding to and connected to each of the air ducts 411 may be provided inside the diversion cavity, and each of the guide channels may be connected and merged to form a main guide channel, and the air supply pipe 421 is connected to the main guide channel.
