Description

Upper limb support device

Technical Field

The utility model belongs to the technical field of medical auxiliary equipment, and particularly relates to an upper limb supporting device.

Background technique

For some examinations or treatments, the patient needs to lie on his back on the bed with both upper arms raised and placed above the forehead, and maintain this position to complete the examination or treatment, such as abdominal examination with a magnetic resonance imaging machine and radiotherapy for patients with chest and abdominal tumors.

Taking abdominal MRI examination as an example, the upper limb lifting position can enhance the image quality, especially the coronal image, fat suppression and coronal enhanced image after medication. However, for patients, because upper limb lifting is not a natural movement, some patients may not be able to maintain the lifting position due to weak constitution, limb deformity and numbness from long-term lifting, which affects the imaging effect of MRI examination.

Some patients with frozen shoulder and difficulty in abduction and extension of the shoulder have limited upper limb lifting angles during examination or treatment. General cushions cannot effectively support the upper limbs of these patients. Also, due to the disease in the shoulder, they are unable to actively complete the upper limb lifting movement, making examination or treatment impossible.

Utility Model Content

The utility model aims to provide an upper limb support device to solve the problem that patients cannot keep their upper limbs lifted stably during examination or treatment, and patients with periarthritis of the shoulder or shoulder difficulties cannot complete upper limb lifting, resulting in poor examination or treatment results.

The technical solutions adopted to solve the above technical problems are:

The utility model discloses an upper limb supporting device, comprising:

A head pad, the head pad being provided with a head and neck cavity for supporting the head and neck;

A limb support pad, the limb support pad is laid around the head pad, the limb support pad comprises a first support member for supporting a patient's forearm and a second support member for supporting a patient's upper arm, the first support member and the second support member are connected;

The head pad is connected to the base, the limb support pad is movably connected to the base, and an angle adjustment mechanism is provided between the limb support pad and the base.

The utility model has at least the following beneficial effects: during examination or treatment, the patient's head and neck and the raised upper limbs are supported by the upper limb support device. The patient's head and neck are placed in the head and neck cavity of the head pad, and the patient's upper limbs are against the limb support pad after being raised. The patient does not need to actively maintain the upper limb raised posture, avoiding the situation where the patient's upper limbs shake or cannot be raised due to weak constitution, limb deformity or numbness after long-term lifting, resulting in unclear examination or poor treatment effect.

In addition, the limb support pad can move relative to the base, and an angle adjustment mechanism is provided between the base and the limb support pad. The angle adjustment mechanism is used to adjust the angle between the base and the limb support pad, so that the limb support pad can provide effective support for patients with periarthritis of the shoulder and difficulty in abduction and lifting of the shoulder, so that the angle between the limb support pad and the base can fit the angle between the patient's upper arm and the base, thereby effectively supporting the patient's upper limb.

As a further improvement of the above technical solution, the first support member and the second support member are fixedly connected, and the first support member and the second support member are arranged at an angle.

Through the above arrangement, since the first support member and the second support member are fixedly connected, the angle between the first support member and the second support member is fixed. The angle between the first support member and the second support member can be set according to the elbow joint angle of most patients when lifting their upper limbs, so that the limb support pad can firmly support the patient's upper arm and forearm.

As a further improvement of the above technical solution, one end of the second support member away from the first support member is hinged to the base, one end of the angle adjustment mechanism is connected to the base, and the other end is connected to the limb support pad to adjust and fix the angle between the second support member and the base.

Through the above arrangement, since the second support member is used to support the patient's upper arm, the angle between the second support member and the base can be adjusted through the angle adjustment mechanism to the angle between the patient's upper arm and the base when the patient is lifted, so that the second support pad can effectively and comfortably support the patient's upper arm.

As a further improvement of the above technical solution, the angle adjustment mechanism includes an adjusting rod, an adjusting bolt and a mounting seat. The two ends of the adjusting rod are respectively hinged to the limb support pad and the mounting seat. An adjusting bolt is fixed to the mounting seat. Adjustment grooves are opened on opposite sides of the base. The adjusting bolt passes through and slides in the adjusting groove. The other side of the adjusting bolt passing through the adjusting groove is threadedly connected with an adjusting nut.

Through the above arrangement, the adjusting rod, the limb support pad and the base form a triangular structure, and the angle adjustment mechanism can firmly support the limb support pad. Since the adjusting bolt can slide in the adjusting groove, the length from the mounting seat to the hinged end of the base and the second support member can be changed, so that the angle between the limb support pad and the base can be changed, thereby realizing the angle adjustment function between the limb support pad and the base, so that the limb support pad can firmly support the patient's upper limb.

As a further improvement of the above technical solution, the first support member and the second support member are rotatably connected.

Through the above arrangement, the rotatably connected first support member and the second support member can adjust the angle between the two so that the angle can fit the elbow joint angle between the patient's forearm and upper arm, thereby improving the comfort of the patient's upper limb placement.

As a further improvement of the above technical solution, the first support member and the second support member are hinged to each other, and the hinge axis extends in the horizontal direction, the output end of the angle adjustment mechanism can move horizontally in a direction perpendicular to the hinge axis, and the ends of the first support member and the second support member that are away from each other are hinged to the output end of the angle adjustment mechanism and the base respectively.

Through the above arrangement, since one end of the first support member is hinged to one end of the second support member, the other end of the first support member is hinged to the output end of the angle adjustment mechanism, and the other end of the second support member is hinged to the base, the first support member, the second support member and the output end of the angle adjustment mechanism form a triangular structure, and the angle between the first support member and the second support member or the angle between the second support member and the base can be adjusted by the angle adjustment mechanism, so that the first support member and the second support member can firmly support the patient's forearm and upper arm.

As a further improvement of the above technical solution, the angle adjustment mechanism is a screw mechanism.

The output end of the screw mechanism can accurately drive one end of the first support member to move in a straight line, ensuring that the angle between the first support member and the second support member can accurately fit the patient's elbow joint angle, or the angle between the second support member and the base can accurately fit the patient's shoulder joint angle, providing comfortable support for the patient, with a simple structure and reliable transmission.

As a further improvement of the above technical solution, the limb support pad is a U-shaped structure, and the two first support members extend toward one end close to each other and are connected.

The U-shaped structure of the limb support pad can connect the first support parts supporting the patient's left forearm and right forearm together, making it convenient for medical staff to operate the angle adjustment mechanism to uniformly adjust the limb support pads, saving adjustment time and operating steps, reducing the number of angle adjustment mechanisms to be installed, and reducing the cost of the upper limb support device.

As a further improvement of the above technical solution, two limb support pads are provided, and the two limb support pads are respectively located on opposite sides of the head pad.

Through the above settings, medical staff can adjust the angle according to the lifting angle of the patient's left upper limb, the lifting angle of the right upper limb or the elbow joint angles on both sides, so that each limb support pad can better support the patient's left upper limb and right upper limb, providing comfortable support for the patient.

As a further improvement of the above technical solution, fasteners are provided at opposite ends of the base for detachable connection with the hospital bed.

Through the above arrangement, the upper limb support device can be detachably connected to the hospital bed. When the patient needs to lift his upper limbs during examination or treatment, the base can be connected to the bed through fasteners so that the patient can obtain support for his upper limbs through the limb support pad.

1 to 6 , several embodiments of the upper limb support device of the present invention are given below.

As shown in FIGS. 1 to 6 , the upper limb support device according to the embodiment of the present invention includes a head pad 100 , a limb support pad 200 and a base 300 .

In this embodiment, a head and neck cavity 110 is provided on the upper end surface of the head pad 100. The head and neck cavity 110 is used to provide support for the patient's head and neck so that the patient can lie on his back comfortably on the bed.

In this embodiment, the limb support pad 200 is used to provide support for the patient's upper limbs. When the patient needs to lift his upper limbs in a supine position, the patient can directly place his upper limbs on the limb support pad 200, and the limb support pad 200 provides effective support for the patient's upper limbs without the need for the patient to actively lift them. The limb support pad 200 can also enable the patient to keep the upper limbs in the lifted position, thereby improving the examination and treatment effects and avoiding the patient's inability to keep the upper limbs in the lifted position due to weak constitution, limb deformities, and numbness and soreness from long-term lifting.

It can be understood that when the patient is in a supine position and raises his upper limbs, the patient's upper limbs are close to the patient's head, so the limb support pad 200 is laid around the head pad 100 .

In this embodiment, the limb support pad 200 includes a first support member 210 and a second support member 220, which are laid along the front-to-back direction so that the first support member 210 and the second support member 220 can effectively support the patient's forearm and upper arm respectively, as shown in Figures 1 to 6.

In this embodiment, the head pad 100 is connected to the base 300, and the limb support pad 200 is movably connected to the base 300. The base 300 is used to fix the head pad 100 and support the limb support pad 200. The base 300 is connected to the hospital bed to facilitate the installation of the upper limb support device on the bed.

In this embodiment, an angle adjustment mechanism 400 is provided between the limb support pad 200 and the base 300, and the angle adjustment mechanism 400 can be used to adjust the angle between the second support member 220 and the base 300, with the angle between the second support member 220 and the base 300 being the first angle.

It is understandable that, due to the illness of patients with periarthritis of the shoulder, kyphosis, etc., when performing upper limb lifting positioning movements, the lifting angle of the upper limbs is limited, and the angle formed between the upper arm and the base 300 is not uniform for each patient when lifting the upper limb. If the angle of the first angle is set according to the angle that a normal person can lift, then for patients with hunchbacks, etc., the upper limb support device cannot effectively support the patient's upper arm; if the angle of the first angle is set according to the angle that a patient with hunchbacks, etc. can lift, then for ordinary patients, the angle between the upper arm and the base 300 is too large, and the patient's upper arm cannot obtain comfortable and labor-saving support from the second support member 220.

Therefore, medical staff can adjust the first angle through the angle adjustment mechanism 400 according to the needs of the patient, so that patients with periarthritis of the shoulder, kyphosis, or patients with difficulty in shoulder abduction and lifting can complete the upper limb lifting positioning movement comfortably and effectively.

It can be understood that the head and neck cavity 110 bends and extends downward along the upper end surface of the head pad 100 to provide a comfortable placement arc for the back of the patient's head. The head and neck cavity 110 is connected to the rear end of the head pad 100 to provide a placement space for the patient's neck.

In some embodiments, the first support member 210 and the second support member 220 are fixedly connected, as shown in Figures 1 to 3. That is, the first support member 210 and the second support member 220 can be fixed by integral molding, welding, gluing, etc., so that the angle of the second angle is fixed, and the limb support pad 200 can stably support the patient's upper limb.

It is understandable that the first support member 210 and the second support member 220 are arranged at an angle. Since the forearm and the upper arm of the patient are not necessarily placed in a straight state on the limb support pad 200 when the patient's upper limb is lifted, the first support member 210 and the second support member 220 arranged at an angle can fit the elbow angle between the forearm and the upper arm of the patient, so that the first support member 210 and the second support member 220 can better support the forearm and the upper arm of the patient, and the angle between the first support member 210 and the second support member 220 is the second angle.

It can be understood that the limb support pad 200 can be an integrally formed triangular prism pad, that is, when viewed from the left and right directions, the limb support pad 200 is triangular. At this time, the first support member 210 and the second support member 220 are respectively the two end faces above the triangular prism pad, and the bottom of the triangular prism pad abuts the base 300, as shown in Figures 1 to 3.

It can be understood that the second angle should be selected as the elbow angle that most patients can achieve when lifting their upper limbs.

It can be understood that when the first support member 210 and the second support member 220 are fixedly connected, the base 300 and the second support member 220 are hinged at one end away from the first support member 210, that is, the base 300 is hinged to the rear end of the second support member 200, and the two ends of the angle adjustment mechanism 400 are respectively connected to the base 300 and the limb support pad 200 to adjust and fix the angle between the second support member 220 and the base 300, so that the angle of the first angle fits the angle between the base 300 and the raised upper arm when the patient is lifted, ensuring that the second support member 220 can firmly support the patient's upper arm.

In this regard, as shown in Figures 1 to 3, the angle adjustment mechanism 400 includes an adjustment rod 520, an adjustment bolt 540 and a mounting seat 510. The two ends of the adjustment rod 520 are respectively hinged to the lower end of the limb support pad 200 and the mounting seat 510. The mounting seat 510 is fixed with an adjustment bolt 540 whose axis extends left and right. Adjustment grooves 530 are opened on the left and right sides of the base 300. The adjustment grooves 530 extend in the front-to-back direction. The adjustment bolt 540 passes through the adjustment groove 530, and an adjustment nut 550 is threadedly connected to the other side of the adjustment groove 530.

It can be understood that since the adjustment rod 520, the hinged end of the self-adjusting rod 520 and the limb support pad 200 to the hinged end of the second support member 220 and the base 300, and the hinged end of the second support member 220 and the base 300 to the hinged end of the adjustment rod 520 and the mounting seat 510 form a triangular stable structure, and the length of the adjustment rod 520 and the length between the hinged end of the self-adjusting rod 520 and the second support member 220 to the hinged end of the second support member 220 and the base 300 are fixed, medical staff can slide back and forth along the adjustment slot 530 by adjusting the bolt 540 to change the length between the mounting seat 510 and the hinged end of the base 300 and the second support member 220, thereby achieving the angle adjustment of the first angle, and the adjusting bolt 540 and the adjusting nut 550 can enable the second support member 220 to firmly support the patient's upper arm, providing a comfortable support effect for the patient.

In other embodiments, the first support member 210 and the second support member 220 are rotatably connected, as shown in Figures 4 to 6. The first support member 210 and the second support member 220 can rotate relative to each other, so that the angle of the second angle can be adjusted, so that the second angle can better fit the elbow angle between the patient's forearm and upper arm, thereby improving the comfort of the patient's upper limb placement.

It can be understood that the first support member 210 and the second support member 220 are hinged at one end close to each other, and the hinge axis 650 extends in the horizontal direction. Since the first support member 210 and the second support member 220 are laid in the front-to-back direction, in this embodiment, the hinge axis 650 extends in the left-right direction, and the first support member 210 and the second support member 220 can rotate around the hinge axis 650 extending to the left and right to change the angle of the second angle.

It can be understood that the angle adjustment mechanism 400 is fixedly connected to the base 300 so that the two are relatively fixed; the output end of the angle adjustment mechanism 400 moves horizontally in a straight line direction, and the moving direction is perpendicular to the hinge shaft 650. Since the hinge shaft 650 extends in the left and right direction, the output end of the angle adjustment mechanism 400 moves in the front and back direction, and the end of the first support member 210 away from the second support member 220 is hinged to the output end of the angle adjustment mechanism 400, and the end of the second support member 220 away from the first support member 210 is hinged to the base 300, as shown in Figures 4 to 6.

Since the rear end of the first support member 210 is hinged to the front end of the second support member 220, the front end of the first support member 210 is hinged to the output end of the angle adjustment mechanism 400, and the rear end of the second support member 220 is hinged to the base 300, and since the angle adjustment mechanism 400 and the base 300 are fixedly connected, a triangular stable structure can be formed between the first support member 210, the second support member 220 and the output end of the angle adjustment mechanism 400, and the first angle, the second angle and the angle between the first support member 210 and the sliding seat 630 are added to form the sum of the internal angles of the triangle, and since the length of the first support member 210 and the length of the second support member 220 are fixed, the size of the first angle can be adjusted with the size of the second angle.

It can be understood that when the output end of the angle adjustment mechanism 400 drives the first support member 210 to move forward, the length between the front end of the first support member 210 and the rear end of the second support member 220 increases, the height of the hinged end of the first support member 210 and the second support member 220 decreases, the angle of the second angle becomes larger, and the angle of the first angle becomes smaller; when the output end of the angle adjustment mechanism 400 drives the first support member 210 to move backward, the length between the front end of the first support member 210 and the rear end of the second support member 220 decreases, the height of the hinged end of the first support member 210 and the second support member 220 increases, the angle of the second angle becomes smaller, and the angle of the first angle becomes larger.

It is understandable that medical staff can change the length between the ends of the first support member 210 and the second support member 220 that are away from each other through the angle adjustment mechanism 400, thereby achieving an angle change of the first angle or the second angle, so that the first angle or the second angle can be adjusted according to the shoulder joint angle or elbow joint angle of different patients when lifting their upper limbs, so that the first support member 210 or the second support member 220 can more effectively support the patient's upper limbs.

In this embodiment, the angle adjustment mechanism 400 is a screw mechanism, as shown in FIGS. 4 to 6 . Specifically, the screw mechanism includes a driving source 610, a transmission screw 620, a sliding seat 630 and a guide rod 640. The driving source 610 is connected to the base 300, and the output end of the driving source 610 is transmission-connected to the transmission screw 620; the transmission screw 620 extends forward and backward and is rotatably mounted on the base 300 so that the transmission screw 620 can rotate relative to the base 300; the sliding seat 630 is sleeved and meshed with the transmission screw 620, and the end of the first support member 210 away from the second support member 220 is hinged to the sliding seat 630, that is, the front end of the first support member 210 is hinged to the sliding seat 630, and the hinge shaft 650 therebetween extends in the left and right direction, and the guide rod 640 is mounted on the base 300, and the guide rod 640 and the transmission screw 620 are parallel to each other, and the guide rod 640 is penetrated in the sliding seat 630 to guide the forward and backward movement of the sliding seat 630.

It can be understood that when the driving source 610 is started, the output end of the driving source 610 drives the transmission screw 620 to rotate. Since the sliding seat 630 is meshed with the transmission screw 620, the rotating transmission screw 620 drives the sliding seat 630 to move forward and backward to change the relative position of the sliding seat 630 and the base 300, thereby changing the length between the front end of the first support member 210 and the rear end of the second support member 220 to achieve the angle adjustment of the first angle or the second angle, and when the driving source 610 is not started, the relative position of the sliding seat 630 and the base 300 is fixed to fix the first angle and the second angle, and there is no need to set up an additional fixing structure. The structure is simple and convenient.

In this embodiment, the driving source 610 is a motor, so that the angle adjustment of the first angle or the second angle is automatically adjusted, so that medical staff can save time and effort during the adjustment process and improve work efficiency.

In another embodiment, the driving source 610 can be a handle that is rotatably mounted on the base 300. Medical personnel can more accurately adjust the first angle or the second angle by rotating the handle. Moreover, when the upper limb support device is used for magnetic resonance imaging, non-motor drive can avoid the use of metal parts in the screw mechanism.

It is understandable that the angle adjustment mechanism 400 can also be a linear drive mechanism such as a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.

It can be understood that when the first support member 210 and the second support member 220 are hinged to each other, if the length of the first support member 210 is equal to the length of the second support member 220, and the hinge positions of the two and the sliding seat 630 and the base 300 are symmetrical, then at this time, the angle between the first support member 210 and the sliding seat 630 is also the first angle. Since the sum of the angles of the two first angles and one second angle is the sum of the internal angles of the triangle, the angle of the first angle is directly affected by the angle of the second angle.

It can be understood that no matter whether the first support member 210 and the second support member 220 are fixedly connected or rotatably connected, the rear end of the second support member 220 and the base 300 are hinged to each other, and the hinge axis 650 extends in the left and right directions to prevent the second support member 220 from moving relative to the base 300, resulting in the second support member 220 being unable to stably support the patient's upper arm.

In some embodiments, the limb support pad 200 is a U-shaped structure, and the two first support members 210 extend toward one end close to each other and are connected to the front of the head pad 100 .

It can be understood that the U-shaped limb support pad 200 can uniformly adjust the limb support pad 200. When the first support member 210 and the second support member 220 are fixedly connected, the angle adjustment mechanism 400 can uniformly adjust the first angle on the left and right sides; when the first support member 210 and the second support member 220 are rotatably connected, the angle adjustment mechanism 400 can uniformly adjust the first angle on the left and right sides, and can also uniformly adjust the second angle, saving adjustment time and operating steps, and reducing the number of angle adjustment mechanisms 400 to be laid.

It is understandable that when the limb support pad 200 is a U-shaped structure, the patient can overlap his hands and place them at the connection between the two first support members 210 when lifting the upper limbs, so that the patient can maintain the lifting action.

It is understandable that when patients lift their upper limbs, the lifting angles of the left and right upper limbs may be different. For example, some patients with periarthritis of the shoulder may only suffer from periarthritis of the shoulder on one side. Therefore, the U-shaped limb support pad 200 may cause only one side of the patient's upper limb to be comfortably supported.

In this embodiment, two limb support pads 200 are provided and both are in a straight line structure, and the two limb support pads 200 are respectively located on the left and right sides of the head pad 100, as shown in Figures 1 to 6. The two limb support pads 200 are independently provided and are respectively connected to an angle adjustment mechanism 400, so that medical staff can make corresponding adjustments according to the lifting angle of the patient's left upper limb, the lifting angle of the right upper limb, or the left and right elbow joint angles, so that the limb support pads 200 can better support the patient's upper limbs.

It is understandable that fasteners 310 are provided at opposite ends of the base 300, and the fasteners 310 are used to detachably connect the upper limb support device to the bed, as shown in Figures 1 to 6. For example, when a patient undergoes an MRI abdominal examination, the upper limb support device can be installed on the bed. When the patient only needs to undergo an ordinary MRI examination and does not need to lift the upper limbs, the patient can lie on his back directly on the bed and rest his head on the head and neck cavity 110. The upper limb support device can also be removed so that the patient can lie directly on the bed.

In this embodiment, connecting parts 320 may extend downward on the left and right sides of the base 300. During installation, the bed can be clamped between the two connecting parts 320. Through holes are provided on the connecting parts 320 and the left and right frames of the bed, and the fasteners 310 can pass through and fix the upper limb support device to the bed.

It is understandable that the fastener 310 may be a connecting structure such as a screw or a bolt.

The preferred implementation methods of the utility model are described in detail above, but the invention of the utility model is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the utility model. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
