Description

TECHNICAL FIELD

[0001] The utility model relates to technical field, specifically is a kind of adjustable lifting pillow of promoting blood return of limbs. BACKGROUND

[0002] Transradial cerebral arteriovenous angiography has become a common and effective diagnostic method. In such operations, patients undergo angiographic procedures through the radial artery, which can clearly show the blood flow state of the brain and related blood vessels, helping doctors make more accurate diagnosis and treatment decisions. However, despite the high success rate of this technique, patients often experience a series of postoperative discomfort symptoms, mainly manifested as pain, swelling of the operative limb, numbness, soreness, etc., especially when the arm or operative limb needs to be suspended for a period of time after surgery, these problems are more prominent.

[0003] Postoperative discomfort symptoms, especially pain and swelling at the surgical site, are usually due to blocked venous return of the operative limb, leading to poor blood circulation. According to medical research, sluggish blood circulation can cause local blood stasis, thereby exacerbating swelling and pain. Especially when performing transradial angiography, the patient's arm or fingers need to be kept at an angle, which can easily lead to poor venous return, and in turn cause finger numbness, arm soreness, swelling, and other discomfort symptoms.

[0004] Currently, the treatment of such postoperative symptoms in clinical practice relies mainly on simple pillows or supports, but most existing designs cannot effectively address the blood return problems caused by the suspension of the operative limb. Traditional pillows are mostly fixed structures and cannot be individually adjusted according to the shape of the patient's operative limb, and cannot effectively reduce the swelling and pain of the operative limb. Especially for patients who need to elevate their arms to a specific height, existing pillows cannot provide sufficient support and adjustability, often causing patients to feel uncomfortable during the postoperative recovery period. INNOVATION CONTENT

[0005] To address the insufficient handling of postoperative pain and swelling in the prior art, an innovative pillow that can support the operative limb and adjust the height to promote blood return is provided. The utility model provides a adjustable lifting pillow for promoting blood return of limbs, comprising:

[0006] The pillow body is a trapezoidal block with a slope on the top surface, and the top surface of the pillow body is provided with a recess for fitting the human arm;

[0007] The front end surface of the pillow body is provided with a palm supporting part that fits the highest point of the recess, and the palm supporting part can be rotated and stored on the front end surface.

[0008] The palm supporting part comprises a first rotating shaft, a supporting plate, a toothed plate, a second rotating shaft and a supporting rod.

[0009] Preferably, the supporting plate is fixedly installed with a top air cushion, which can change the height relative to the supporting plate by changing the internal air pressure.

[0010] Preferably, the lower part of the supporting plate is provided with an avoidance groove matched with the second rotating shaft, the supporting rod enters the avoidance groove when being rotated to fit the bottom surface of the supporting plate, and the avoidance groove is installed with a first magnetic block magnetically matched with the supporting rod.

[0011] Preferably, the groove is provided with a wrist supporting part parallel to the bottom surface on one side of the top surface of the pillow body close to the supporting plate.

[0012] Preferably, the front end surface of the pillow body is provided with a mounting groove, the supporting plate can be downwardly rotated to be completely located in the mounting groove, and the mounting groove is provided with a second magnetic block magnetically attracted to the first magnetic block.

[0013] Preferably, the lower end surface of the supporting plate away from the first rotating shaft is provided with an inner concave chamfer facilitating the rotation of the supporting plate by inserting fingers.

[0014] Preferably, both side surfaces of the pillow body are provided with elastic clamps for clamping a one-time mat.

[0015] Compared with the prior art, the adjustable lifting pillow for promoting blood return of limbs has the following beneficial effects:

[0016] 1. The problem of lack of flexible adjustment of arm position and supporting structure in the prior art is solved, in particular, the blood return is not smooth due to the suspended state of the arm of the patient after operation. By designing a pillow body in the form of a bevel trapezoidal block and setting a recess groove suitable for the shape of the arm on the top surface of the pillow body, the arm of the patient can be properly supported, and the situation of blocked venous return of the operated limb is relieved. The adjustable function of the palm supporting part enables the patient to adjust the supporting position of the hand according to the own needs, ensures the stability and comfort of the arm, and thus reduces swelling and pain, and optimizes the postoperative recovery process.

[0017] 2. The introduction of the air cushion design makes the supporting system of the pillow have higher adaptability and comfort. Through the air pressure adjustment of the air cushion, the patient can conveniently adjust the height of the supporting plate according to personal feelings and needs, so as to more accurately control the supporting position of the arm and palm. Such flexibility helps to more effectively promote the blood return of the operated limb and reduce the swelling and numbness of the arm. At the same time, the air cushion can also provide a softer contact surface to reduce the discomfort caused by hard support. Attached Figure Description

[0022] Example

[0023] The following is combined with Figure 1 and Figure 2 This application introduces an adjustable elevating pillow that promotes blood return in the limbs, including a pillow body, wherein the pillow body is a trapezoidal block 1 with an inclined surface on the top surface, and the top surface of the pillow body has a groove 2 for conforming to the human arm;

[0024] The front end of the pillow body is provided with a palm support portion that fits against the highest point of the groove 2. This palm support portion can be rotated and retracted to fit against the front end. The pillow body is shaped like a sloping trapezoidal block 1, with a groove 2 on its top surface designed to fit the shape of the arm, providing appropriate support for the patient's arm and alleviating venous return obstruction in the operated limb. The adjustable palm support portion allows the patient to adjust the support position of their hand according to their needs, ensuring arm stability and comfort, thereby reducing swelling and pain and optimizing the postoperative recovery process.

[0025] The palm supporting part includes a first rotating shaft 5, a support plate 6, a toothed plate 7, a second rotating shaft 8, and a support rod 13. The support plate 6 is installed on the front end surface of the pillow body through the horizontally arranged first rotating shaft 5. The support rod 13 is rotatably installed on the lower part of the support plate 6 through the second rotating shaft 8. The support rod 13 can be rotated to fit the bottom surface of the support plate 6. The front end surface of the pillow body is provided with the toothed plate 7 which cooperates with the support rod 13. Further, the structure design of the palm supporting part is proposed to make it more flexible and adjustable. By combining the rotating shaft and the toothed plate 7 on the support plate 6, the palm supporting part can be adjusted according to the needs of patients, thereby providing personalized support angle and height for different patients. This design not only ensures effective support of the arm, but also avoids uncomfortable contact between the pillow body and the patient's arm, reducing the compression of the limb after the operation.

[0026] The support plate 6 is fixedly installed with a top air cushion 12. The height of the top air cushion 12 relative to the support plate 6 can be changed by changing the internal air pressure. The introduction of the air cushion design makes the support system of the pillow more adaptable and comfortable. Through the air pressure adjustment of the air cushion, the patient can conveniently adjust the height of the support plate 6 according to personal feelings and needs, thereby more accurately controlling the support position of the arm and palm. This flexibility helps to more effectively promote blood flow of the operated limb and reduce arm swelling and numbness. At the same time, the air cushion can also provide a softer contact surface to reduce discomfort caused by hard support.

[0027] The lower part of the support plate 6 is provided with an avoidance groove 9 which is adapted to the second rotating shaft 8. When the support rod 13 is rotated to fit the bottom surface of the support plate 6, it enters the avoidance groove 9. A first magnetic block 10 which magnetically cooperates with the support rod 13 is installed in the avoidance groove 9. The design of the avoidance groove 9 and the magnetic block makes the support rod 13 more stable and accurate when rotating, and can effectively fix the posture of the support rod 13. The magnetic adsorption can reduce the wear between the support rod 13 and the support plate 6,

[0028] The groove 2 is provided with a wrist supporting part 3 which is parallel to the bottom surface on one side of the top surface of the pillow body near the support plate 6. The design of the wrist supporting part 3 takes into account the support needs of the natural curve of the arm. The wrist supporting part 3 in combination with the groove 2 can provide additional wrist support for the patient to prevent uncomfortable pressure or fatigue at the wrist. Through this design, the pillow body can better distribute the weight of the arm, reduce the problem of blocked venous return, and relieve the compression and fatigue of the wrist, ensuring the comfort and effectiveness of the patient during postoperative recovery

[0029] The front end surface of the pillow body is provided with a mounting groove 4, and the support plate 6 can be rotated downward to be completely located in the mounting groove 4. The mounting groove 4 is provided with a first magnetic block 10 and a second magnetic block 14 which are magnetically attracted to each other. The design of the mounting groove 4 and the magnetic block enables the support plate 6 to be conveniently stored in the pillow body when not in use, saving space and improving portability. In addition, the design of magnetic attraction can ensure the stability of the support plate 6, prevent it from moving or loosening accidentally during use, and enhance the reliability and safety of the equipment.

[0030] The lower end surface of the support plate 6 away from the first rotating shaft 5 is provided with an inner recessed chamfer 11 for inserting fingers to rotate the support plate 6. The design of the inner recessed chamfer 11 allows patients or medical staff to operate the support plate 6 more easily, especially when adjusting the angle or height, the inner recessed chamfer 11 provides a better holding position, enhancing the convenience and comfort of operation.

[0031] Both sides of the pillow body are provided with elastic clamps 15 for clamping disposable pads. A simple and effective method is provided for fixing disposable pads. Patients need to keep the surgical limb clean and hygienic after surgery, and the clamping function of the pad can avoid the pad from sliding or shifting, keeping the clean area stable. This design not only increases the hygiene of the product, but also reduces the complexity of postoperative care.
