Description

Technical Field

[0001] The invention belongs to the technical field of medical auxiliary appliances, and in particular relates to a body position pad capable of automatically adjusting limb pressure. Background Art

[0002] Positioning pads are widely used in various clinical departments. The most common ones are limb positioning pads. By placing limb positioning pads under the limbs, they can assist in supporting the limbs, reduce limb pressure, help the limbs maintain functional positions, promote blood return, etc., and have positive effects on long-term bedridden patients and patients in the rehabilitation stage.

[0003] The positioning pad in the prior art has a simple structure, and is generally provided with a sponge pad or memory foam pad that fits the shape of the limbs to support the limbs. However, the limbs need to be turned over at all times during the support process to avoid long-term pressure on local tissues and pressure sores. It cannot automatically adjust the pressure on the limbs, and the use effect is limited and inconvenient. Therefore, in response to the above problems, we propose a positioning pad that automatically adjusts the pressure on the limbs. Summary of the invention

[0004] In view of the above problems, the purpose of the present invention is to provide a body positioning pad that automatically adjusts the pressure on the limbs, which can automatically adjust the pressure on the limbs, avoid pressure sores caused by long-term pressure on local tissues, and increase the convenience of use.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: a body positioning pad that automatically adjusts limb pressure, comprising a box body, an adjustment component and a control module, a support portion is provided on the top of the box body, the top surface of the support portion is made of a flexible material and fits the limb, the adjustment component is divided into multiple groups, and the multiple groups of the adjustment components are all arranged between the box body and the support portion, each group of the adjustment components includes multiple electric telescopic rods and pressure plates arranged above the multiple electric telescopic rods, the multiple pressure plates are tightly fitted to each other and adapted to the inner top surface of the support portion, and the control module is arranged on the box body for adjusting the pressure of each group of adjustment components on the limb.

[0006] The beneficial effects of the present invention are: by automatically and intermittently controlling the timed extension and retraction of multiple electric telescopic rods in different groups in the control module, the corresponding pressure plates are raised and lowered, reducing or restoring the pressure of the pressure plates on the limbs, avoiding local continuous pressure on the limbs, and being more convenient to use.

[0007] To facilitate disassembly and maintenance;

[0008] As a further improvement of the above technical solution: the box body and the support part are detachably connected, the bottom of the pressure plate is rotatably connected with a rotating sleeve, and the upper end of the electric telescopic rod is threadedly connected to the inner wall of the rotating sleeve.

[0009] The beneficial effect of this improvement is that when the interior of the box body needs to be inspected, the box body and the support part are disassembled, and then the rotating sleeve is rotated so that the rotating sleeve can be separated from the electric telescopic rod, thereby disassembling each component to facilitate targeted inspection and replacement.

[0010] To facilitate automatic adjustment;

[0011] As a further improvement of the above technical solution: the control module includes a timer, a microprocessor electrically connected to the timer, and a controller electrically connected to the microprocessor, and the controller is electrically connected to the electric telescopic rod.

[0012] The beneficial effect of this improvement is that a certain replacement time is set through a timer during use. After the pressure relaxation of each group of adjustment components is completed, the timer transmits a signal to the microprocessor, which then analyzes and judges the signal and transmits the signal to the controller. The controller controls the next group of electric telescopic rods to drive the pressure plate to descend and relax the corresponding limb position.

[0013] For proper buffering;

[0014] As a further improvement of the above technical solution: a plurality of elastic balls are evenly arranged on the pressure plate.

[0015] The beneficial effect of this improvement is that when the limbs are placed on the support part, the elastic balls are compressed, which can provide appropriate buffering for the pressure on the limbs, can better adapt to the changes in the pressure on the limbs, and provide more uniform support.

[0016] To avoid cross infection;

[0017] As a further improvement of the above technical solution: the upper end of the support part is detachably connected with a protective pad.

[0018] The beneficial effect of this improvement is that each patient can have a protective pad individually, and then install the protective pad when in use, and remove the protective pad when not in use, thereby avoiding contamination and reducing cross infection between patients.

[0019] In order to use this device stably;

[0020] As a further improvement of the above technical solution: an anti-slip pad is provided at the bottom of the box body.

[0021] The beneficial effect of this improvement is that the provision of the anti-slip pad can increase the friction between the box body and the bed body after the box body is placed on the bed, reduce the random movement of the box body, and increase stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.

[0029] like Figure 1-5 As shown, a body position pad for automatically adjusting limb pressure includes a box body 1, a support part 2 is arranged on the top of the box body 1, the top surface of the support part 2 is made of a flexible material and fits the limb, the top surface of the support part 2 can be made of a cotton pad, a sponge pad or the like, and also includes an adjustment component and a control module, the adjustment component is a plurality of groups, the plurality of groups of adjustment components are arranged between the box body 1 and the support part 2, each group of adjustment components includes a plurality of electric telescopic rods 301 and pressure plates 302 arranged above the plurality of electric telescopic rods 301, the plurality of pressure plates 302 are tightly fitted to each other and matched with the inner top surface of the support part 2, the control module is arranged on the box body 1 for adjusting each group of adjustment components The pressure of the component on the limbs is exerted by setting the time for each group of electric telescopic rods 301 to drive the pressure plates 302 to descend through the control module during use. When one group of pressure plates 302 descends, the remaining pressure plates 302 support the limbs, and the pressure on the limbs at the descending pressure plates 302 is relatively small. After a period of time, the control module controls this group of electric telescopic rods 301 to drive the pressure plates 302 to rise and return to their original positions, and then controls another group of electric telescopic rods 301 to drive the corresponding pressure plates 302 to descend, thereby reducing the pressure at another limb position. This is repeated, thereby avoiding long-term pressure on local tissues, and automatic adjustment also increases the convenience of use.

[0030] Furthermore, the box body 1 and the support part 2 are detachably connected, the bottom of the pressure plate 302 is rotatably connected with a rotating sleeve 5, and the upper end of the electric telescopic rod 301 is threadedly connected to the inner wall of the rotating sleeve 5, wherein the box body 1 and the support part 2 can be detachably connected by means of magnetic attraction, snap-on connection, etc. During use, the inside of the box body 1 may need to be inspected due to a long period of use. At this time, the support part 2 is removed from the box body 1, and then the rotating sleeve 5 at the bottom of the pressure plate 302 is rotated to separate the rotating sleeve 5 from the electric telescopic rod 301, thereby separating the pressure plate 302 from the electric telescopic rod 301, thereby facilitating targeted inspection of each component.

[0031] Furthermore, the control module includes a timer 401 arranged on the box body 1, a microprocessor 402 electrically connected to the timer 401, and a controller 403 electrically connected to the microprocessor 402. The controller 403 is electrically connected to the electric telescopic rod 301. When in use, a certain time is set through the timer 401. When the time is up, the timer 401 transmits a signal to the microprocessor, and the microprocessor 402 transmits a signal to the controller 403. The controller 403 controls one group of pressure plates 302 to descend and the other group of pressure plates 302 to return to their original positions, thereby intermittently relaxing the pressure on different parts of the limbs.

[0032] Furthermore, a plurality of elastic balls 6 are evenly arranged on the pressure plate 302, wherein the elastic balls 6 can be made of rubber, silicone or other materials. By arranging a plurality of elastic balls 6, when the patient's legs are placed on the support part 2, the elastic balls 6 are squeezed and deformed, and provide appropriate buffering for the pressure of the limbs, which can better adapt to the changes in limb pressure and provide more uniform support.

[0033] Furthermore, the upper end of the support part 2 is detachably connected with a protective pad 7, wherein the protective pad 7 may be made of non-woven fabric, a mid-sheet, etc., which is skin-friendly and comfortable while preventing the support part 2 from being contaminated, and may be detachably connected to the support part 2 by Velcro, adhesive, etc., which avoids contamination while reducing cross infection between patients.

[0034] Furthermore, an anti-skid pad 8 is provided at the bottom of the box body 1, wherein the anti-skid pad 8 may be made of rubber, silicone or other materials. The setting of the anti-skid pad 8 can increase the friction between the box body 1 and the bed after the box body 1 is placed on the bed during use, thereby reducing the random movement of the box body 1 and increasing stability.

[0035] The working principle and use process of the present invention are as follows: when using the device, first replace the clean protective pad 7, then place the box body 1 on the bed, fix it with the anti-slip pad 8, then place the limbs on the protective pad 7, and at the same time, the squeezed elastic ball 6 is deformed to appropriately buffer the pressure, and then the time for intermittent replacement of multiple groups of adjustment components is set by the timer 401. When the time is up, the timer 401 transmits a signal to the microprocessor 402, and the microprocessor 402 transmits a signal to the controller 403. The controller 403 controls one group of electric telescopic rods 301 to drive the pressure plate 302 to descend, and another group of electric telescopic rods 301 drives the pressure plate 302 to return to its original position, and so on and so forth, so that different positions of the limbs can be evenly and appropriately relaxed, reducing pressure sores caused by long-term pressure on local tissues, and the setting of the control module increases the convenience of use.
