Description

Technical Field

[0001] The utility model belongs to the field of medical auxiliary equipment, in particular to a multifunctional limb placement pillow for hemiplegic patients. Background Art

[0002] Hemiplegic patients suffer from motor dysfunction in one limb. Maintaining the same posture for a long time can easily lead to complications such as pressure injuries and joint contractures, which affect the recovery process and quality of life. Currently, pillows, sponge pads or fixed limb supports are commonly used in clinical practice to support patients' limbs in different postures. Fixed or simply adjustable support tools are difficult to adapt to the physical differences of different patients, resulting in unsatisfactory support effects. When using pillows or sponge pads, the mobility of the pillow body or sponge itself often causes displacement, causing the originally placed pillow or sponge to lose its proper support effect. Therefore, caregivers need to frequently adjust and rearrange them to adapt to changes in the patient's body position, increasing their workload. In addition, in traditional limb support methods, patients can verbally tell caregivers about the discomfort caused by limb compression when they are awake. However, it is difficult to monitor limb compression when the patient is asleep. If high-force compression is applied for a long time, permanent damage may occur, which needs to be improved.

DETAILED DESCRIPTION

[0028] The present invention is further described below through specific implementation methods.

[0029] Reference Figures 1 to 4 As shown, a multifunctional limb placement pillow for hemiplegic patients includes a base pad 1, a headrest 2, a first limb pillow 3, a second limb pillow 4, a pressure monitoring system 5, and a power supply module 6. The headrest 2, multiple first limb pillows 3, and multiple second limb pillows 4 can be combined and placed on the base pad 1 to adapt to the body position and posture of the hemiplegic patient.

[0030] The base pad 1 is provided with a plurality of female button heads 7. The bottom surface of the first limb pillow 3 is provided with two male button heads 8, and the top surface is provided with two female button heads 7 located opposite the male button heads 8. The bottom surface of the second limb pillow 4 is provided with two male button heads 8. The male button heads 8 cooperate with the female button heads 7 to complete the combined installation of the first limb pillow 3 and the second limb pillow 4 on the base pad 1. The first limb pillow 3 and the second limb pillow 4 are internally divided into two pillow bodies 9 facing each other. The pillow bodies 9 are provided with an inflatable airbag 91 connected to the outside. The airbag 91 is provided with an air nozzle 92 that can be opened or closed for deflation or inflation, which facilitates inflation and deflation to further adjust the pillow height to meet the different needs of different patients.

[0031] Specifically, the top surface of the female button 7 is recessed downward to form a groove 71, and the male button 8 is formed with an ellipsoidal protrusion 81 that can extend into the groove 71. There are symmetrical retaining springs 72 on both sides of the groove 71 to prevent the protrusion 81 from falling out. This structure is a common push-button structure in the prior art, and this application only briefly describes its structure.

[0032] The pressure monitoring system 5 includes a pressure sensor 51, a controller, and a display screen 52. The pressure sensor 51 is laid flat between the two, which can effectively improve the accuracy of the measurement results of the pressure sensor 51. The controller receives the signal fed back by the pressure sensor 51 to monitor the pressure and ensure that the pressure is evenly distributed after the patient's limbs are placed. The display screen 52 is set on the base pad 1, and the controller is integrated into the display screen 52 to display the values monitored by the pressure sensor 51, so that the nursing staff can adjust the patient's posture in time according to the pressure changes to avoid long-term compression of the limbs. Specifically, the pressure sensor 51 is a wireless thin film pressure sensor 51. The controller receives the wireless signal fed back by the pressure sensor 51 and displays it on the display screen 52. Since multiple limb pillows are arranged in series and parallel, it is difficult to arrange the signal transmission circuit to accurately transmit the signal monitored by each pressure sensor 51, so wireless signal transmission is adopted.

[0033] The power supply module 6 includes a first wire 61, a second wire 62, and a contact connector mechanism 63. Two first wires 61 are provided, one end of which is connected to an external power source, and the other end extends around the outer edge 635 of the base pad 1. The button female connector 7 on the base pad 1 is connected in series to the first wire 61. Two second wires 62 are provided, each connected between the button male connector 8 and the button female connector 7 in the first limb pillow 3. The pressure sensor 51 is connected between the two second wires 62 or between the two button male connectors 8 of the second limb pillow 4 to form a power supply circuit. The contact connector mechanism 63 is provided between the button male connector 8 and the button female connector 7 to achieve electrical connection between the two. Power is supplied from the base pad 1 to the pressure sensor 51 through the special power supply module 6, eliminating the need for a built-in battery in the pillow, improving safety and reducing maintenance frequency, making it highly practical.

[0034] Specifically, the power supply module 6 further includes a voltage regulator 64 and a fuse 65. One end of the voltage regulator 64 is connected to the first wire 61, and the other end is connected to the external power supply; the fuse 65 is arranged in the first wire 61 to prevent circuit overload.

[0035] Furthermore, the contact joint mechanism 63 includes a sleeve 631, a slider 632, a contact block 633 and a spring 634. The sleeve 631 is arranged at the bottom of the groove 71 and is connected to the first wire 61 or the second wire 62; the slider 632 can be moved up and down in the sleeve 631; the contact block 633 is arranged on the top surface of the slider 632, and can move up and down with the sleeve 631 to move away from the sleeve 631 or penetrate into the sleeve 631 and contact the inner wall of the sleeve 631. The top surface of the contact block 633 is protruded with outer edges 635 on both sides; the spring 634 is connected between the bottom of the outer edge 635 and the bottom of the groove 71, and the top of the protrusion 81 is connected to the second wire 62 or the pressure sensor 51 above. After the protrusion 81 penetrates into the groove 71, it contacts the contact block 633 and causes the contact block 633 to move downward and contact the inner wall of the sleeve 631. After the protrusion 81 of the button male head 8 is extended into the groove 71 of the button female head 7, the protrusion 81 is difficult to fall out of the protrusion 81 due to the influence of the retaining spring 72. The protrusion 81 contacts the top surface of the contact block 633 and pushes the contact block 633 to move downward and enter the sleeve 631. The upper and lower parts are connected to form an electrical connection. The spring 634 can ensure that the contact block 633 has a tendency to always move upward to contact the protrusion 81, ensuring that the electrical connection will not be disconnected due to the patient's movement on the limb pillow.

[0036] Preferably, the protrusion 81, the contact block 633, and the sleeve 631 are all made of conductive materials, and the button male head 8, the button female head 7, the slider 632 and the spring 634 are all made of insulating materials.

[0037] When in use, according to the patient's affected side and limb placement posture, take different numbers of first limb pillows 3 and second limb pillows 4, and complete the assembly by matching the male button 8 with the female button 7. After the patient lies on the limb placement pillow and completes the corresponding posture, the nursing staff adjusts the patient's posture or deflates or inflates the airbag 91 to achieve the optimal state based on the signal fed back by the pressure sensor 51 on the display screen 52. The patient can then be arranged to rest, and the nursing staff can regularly patrol and observe the values on the display screen 52 on the base pad 1. If abnormal data is found, timely adjustments can be made to avoid long-term compression of the patient's limbs. This application meets the support needs of different patients with different postures to a great extent, and can also perform real-time pressure monitoring to improve the safety of the patient's limbs after placement, and has high practicality.

[0038] The above description is merely a preferred embodiment of the present invention and therefore cannot be used to limit the scope of implementation of the present invention. In other words, equivalent changes and modifications made according to the scope of the patent application and the contents of the specification of the present invention should still fall within the scope of the present patent.
