Description

Technical Field

[0001] This invention belongs to the field of nursing air cushion technology, and particularly relates to a clinical nursing air cushion that facilitates the transfer of patients. Background Technology

[0002] Pressure ulcers are a common complication of long-term bedridden patients and a top priority in basic nursing care. The use of air mattresses is an effective means and important equipment for the prevention and treatment of pressure ulcers. It can effectively reduce local tissue pressure, promote blood circulation in the pressure area, and effectively prevent pressure ulcers by reducing the number of times patients need to turn over or even not turning over. It can also alleviate the pain caused by complications from long-term bed rest and greatly reduce the intensity of clinical nursing work. Therefore, it is widely used in clinical nursing.

[0003] To ensure the softness and ease of roll-up storage, traditional clinical nursing air mattresses use soft materials for both the base and the air bladder. While these mattresses are soft enough, they cannot harden. Therefore, they cannot be used directly when transferring patients. When a patient lies on the mattress, lifting it deforms the mattress, enveloping the patient and potentially causing injury. This also hinders the movement of the patient by nursing staff. Alternatively, the mattress must be installed on the bed and the bed pushed to transfer the patient, or the patient must be moved to the bed or stretcher first. These methods prevent the direct transfer of patients using the air mattress, limiting its application and making patient transfer difficult, thus hindering its widespread use.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide a clinical nursing air cushion that facilitates patient transfer, in order to achieve a more practical value. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides an air cushion for clinical care that facilitates patient transfer, thus solving the issues of direct patient transfer and ease of operation.

[0006] The purpose and efficacy of this invention, a clinical nursing air cushion for facilitating patient transfer, are achieved through the following specific technical means: A clinical nursing air cushion for facilitating patient transfer includes a base plate. The top of the base plate has evenly spaced airbags. A connecting seat is fixedly connected to the inner bottom wall of the base plate, below each airbag. A connecting plate is movably inserted into the connecting seat, and a pushing component is mounted on the connecting plate. A rotating plate is movably mounted inside the connecting seat, to the left of the connecting plate. A limiting plate, inserted into the connecting plate, is fixedly connected to the rotating plate. A support column is fixedly connected to the limiting plate, and an impact ring is movably sleeved on the outer side of the support column. The connecting seat has a positioning groove and a sliding groove corresponding to the impact ring inside. Switch seats are fixedly mounted on the left and right sides of the base plate. An impact rod corresponding to the rotating plate is movably inserted into the switch seat, and a tension spring is mounted on the impact rod.

[0007] Furthermore, an inflation device is installed on the base plate to inflate and deflate the airbag cushion.

[0008] Furthermore, the connecting seat has a through groove inside that corresponds to the connecting plate, and the connecting seats can be fixedly connected to each other as a whole plate through the connecting plate.

[0009] Furthermore, both the connecting seat and the connecting plate are made of rigid materials. When the connecting plate is inserted into the interior of the adjacent connecting seat, the entire base plate can become a solid and rigid plate that will not deform.

[0010] Furthermore, the pushing component includes a telescopic rod, which is connected to the connecting plate and the connecting seat by a movable hinge. A compression spring is provided on the telescopic rod. When the connecting plate moves, the telescopic rod will first be compressed and shortened, and then lengthened under the action of the compression spring. When the telescopic rod lengthens, it will give the connecting plate an impact force.

[0011] Furthermore, the limiting plate includes two plates symmetrical about the rotating plate, and the connecting plate has a limiting groove corresponding to the limiting plate. When the limiting plate is inserted into the connecting plate, it can fix the position of the connecting plate.

[0012] Furthermore, the impact ring is provided with a magnetic sheet, and the end of the rotating plate is provided with a magnetic sheet corresponding to the impact ring. The impact ring is fixed in the positioning groove under the attraction between the two magnetic sheets.

[0013] Furthermore, the end of the support column is provided with a baffle corresponding to the impact ring.

[0014] Furthermore, the width of the positioning groove is greater than the outer diameter of the impact ring, so that when the rotating plate is subjected to force, it can rotate slightly within the positioning groove. When the rotating plate is subjected to rapid impact and rapid rotation, the impact ring will slide into the groove under the action of a larger impact force.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. When a patient needs to be transferred, simply pull the impact lever on the left switch seat and release it. The impact lever, under the action of the tension spring, rapidly impacts the leftmost rotating plate, causing the connecting plate to move to the right. The compression spring exerts a rightward pushing force on the connecting plate, causing it to impact the rotating plate inside the right connecting seat. This causes the right connecting plate to extend to the right as well. In this way, all the connecting plates extend to the right in sequence, connecting the connecting seats together. Therefore, the base plate will not deform. At this time, even if the patient is lying on the airbag cushion, the base plate can be lifted directly to transfer the patient smoothly. This solves the problem that traditional nursing airbags are only soft and cannot harden, making it impossible to lift and transfer patients smoothly.

[0016] 2. By setting a rotating plate and a limiting plate, the connecting plate can be positioned, so that the connecting plate is firmly fixed between the two connecting seats, which increases the stability of the overall structure; by setting an impact ring and a positioning groove to limit the rotating plate, the position of the connecting plate is fixed, which improves the stability of the overall structure after assembly.

[0017] 3. By setting up a switch base, the tension spring provides initial power to the connecting plate. By setting up a push rod assembly, the compression spring in the push rod assembly provides power for the movement of the middle connecting plate. This ensures that the entire process of the base plate hardening can be carried out automatically, and the switching between the soft and firm states of the overall structure is quick and easy, making operation simple and convenient.

[0018] 4. By setting an impact ring and a positioning groove, the impact force generated by the impact of the compression spring can move the impact ring into the groove. This avoids the phenomenon that the connecting plate will loosen due to the downward pressure of the patient when the base plate moves in a hardened state, thus improving the safety and reliability of the patient transfer process.

[0019] 5. By setting up connecting seats and connecting plates, the connecting plates are retracted inside the connecting seats when not in use. There are gaps between the connecting seats, which will not affect the rolling up of the base plate. The base plate can be rolled up for storage, saving space and making it convenient to use.

[0022] The present invention will be further described below with reference to the accompanying drawings: Example: As attached Figure 1 To be continued Figure 8 As shown: This invention provides an air cushion for clinical care that facilitates patient transfer, comprising a base plate 1, with airbags 2 arranged at equal intervals on the top of the base plate 1, a connecting seat 3 fixedly connected to the inner bottom wall of the base plate 1 below each airbag 2, a connecting plate 4 movably inserted into the connecting seat 3, a pushing component 5 installed on the connecting plate 4, a rotating plate 6 movably installed inside the connecting seat 3 on the left side of the connecting plate 4, a limiting plate 7 fixedly connected to the rotating plate 6 and inserted into the connecting plate 4, a support column 8 fixedly connected to the limiting plate 7, an impact ring 9 movably sleeved on the outer side of the support column 8, a positioning groove 10 and a sliding groove 11 corresponding to the impact ring 9 being formed inside the connecting seat 3, a switch seat 12 fixedly installed on the left and right sides of the base plate 1, an impact rod 13 corresponding to the rotating plate 6 being movably inserted into the switch seat 12, and a tension spring 14 installed on the impact rod 13.

[0023] The base plate 1 is equipped with an inflation device for inflating and deflating the airbag cushion 2.

[0024] The connecting seat 3 has a through groove inside that corresponds to the connecting plate 4, and the connecting seats 3 can be fixedly connected to each other as a whole plate through the connecting plate 4.

[0025] Both the connecting seat 3 and the connecting plate 4 are made of rigid materials. When the connecting plate 3 is inserted into the interior of the adjacent connecting seat 4, the entire base plate 1 can become a solid and rigid plate that will not deform.

[0026] The pushing component 5 includes a telescopic rod 501. The telescopic rod 501 is connected to the connecting plate 4 and the connecting seat 3 by a movable hinge. A compression spring 502 is provided on the telescopic rod 501. When the connecting plate 4 moves, the telescopic rod 501 will first be compressed and shortened, and then lengthened under the action of the compression spring 502. When the telescopic rod 501 lengthens, it will give the connecting plate 4 an impact force.

[0027] The limiting plate 7 includes two plates symmetrical about the rotating plate 6. The connecting plate 4 has a limiting groove corresponding to the limiting plate 7. When the limiting plate 7 is inserted into the connecting plate 4, the position of the connecting plate 4 can be fixed.

[0028] The impact ring 9 is provided with a magnetic sheet, and the end of the rotating plate 6 is provided with a magnetic sheet corresponding to the impact ring 9. The impact ring 9 is fixed in the positioning groove 10 under the attraction between the two magnetic sheets.

[0029] The end of the support column 8 is provided with a baffle corresponding to the impact ring 9.

[0030] The width of the positioning groove 10 is greater than the outer diameter of the impact ring 9, so that when the rotating plate 6 is subjected to force, it can rotate slightly within the positioning groove 10. When the rotating plate 6 is subjected to a rapid impact, the impact ring 9 slides into the sliding groove 11 after being subjected to the impact force transmitted from the rotating plate 6.

[0031] The specific usage and function of this embodiment are as follows: In this invention, under normal use, the base plate 1 and the air cushion 2 are filled with gas, and the air cushion 2 supports the patient; in the initial state, such as Figure 2 As shown, the connecting plate 4 in each connecting seat 3 is retracted inside, pushing the component 5 to tilt to the left, which can prevent the connecting plate 4 from extending to the right; the limiting plate 7 on the rotating plate 6 is also stuck inside the connecting plate 4, further enhancing the positional stability of the connecting plate 4; the impact ring 9 is fixed inside the positioning groove 10 under the attraction between the magnetic sheets, thereby preventing the support column 8 and the rotating plate 6 from rotating, which further enhances the stability.

[0032] When a patient needs to be transferred, simply pull the impact rod 13 on the left switch base 12 and release it. The impact rod 13 moves rapidly to the right under the action of the tension spring 14, impacting the leftmost rotating plate 6. The rotating plate 6 transmits the component of the impact force to the impact ring 9. Under the action of the impact force, the impact ring 9 slides into the groove 11 (the impact force brought by the impact rod 13 is greater than the magnetic attraction between the magnetic plates on the impact ring 9), thus avoiding affecting the rotation of the rotating plate 6. Subsequently, the impact rod 13 strikes the connecting plate 4 through the rotating plate 6, and the connecting plate 4 moves to the right, simultaneously pushing the assembly 5 to change as follows. Figure 8In the state shown, the compression spring 502 exerts a rightward pushing force on the connecting plate 4, causing the connecting plate 4 to impact the rotating plate 6 inside the right connecting seat 3. This causes the right connecting plate 4 to extend to the right as well. Furthermore, the rotating plate 6 inside the right connecting seat 3 rotates counterclockwise, and the limiting plate 7 on the right rotating plate 7 locks onto the left connecting plate 4, thus fixing the left connecting plate 4 and preventing it from moving. In this way, all the connecting plates 4 extend to the right, and all the connecting seats 3 are fixedly connected together through the connecting plates 4. Therefore, the entire base plate 1 becomes a rigid plate that will not deform. At this time, even if the patient is lying on the airbag cushion 2, the base plate 1 can be lifted directly upward to transfer the patient smoothly. This solves the problem that traditional nursing airbags can only be soft and cannot harden, making it impossible to lift and transfer the patient smoothly. When the base plate needs to return to its soft state, simply operate the impact rod 13 on the right. The impact force on the rotating plate 6 changes from the impact rod 13 to the connecting plate 4. Its working principle is the same as described above. All the connecting plates 4 will be impacted and retracted in sequence, thus returning to their initial state.

[0033] By setting the rotating plate 6 and the limiting plate 7, the connecting plate 4 can be positioned, so that the connecting plate 4 is firmly fixed between the two connecting seats 3, which increases the stability of the overall structure; by setting the impact ring 9 and the positioning groove 10 to limit the rotating plate 6, the position of the connecting plate 4 is fixed, which improves the stability of the overall structure after assembly.

[0034] By setting the switch base 12, the tension spring 14 provides initial power to the connecting plate 4. By setting the push rod assembly 5, the compression spring 502 in the push rod assembly 5 provides power for the movement of the intermediate connecting plate 4. This ensures that the entire process of the base plate 1 hardening can be carried out automatically, and the switching between the soft and firm states of the overall structure is quick and easy, making operation simple and convenient.

[0035] By setting the impact ring 9 and the positioning groove 10, the impact force brought by the impact of the compression spring 502 can move the impact ring 9 into the sliding groove 22 only after the connecting plate 4 is impacted by the compression spring 502. This avoids the phenomenon that the connecting plate 4 will loosen due to the downward pressure of the patient when the base plate 1 moves in a hardened state, thus improving the safety and reliability of the patient transfer process.

[0036] By setting up connecting base 3 and connecting plate 4, when not in use, connecting plate 3 is retracted inside connecting base 3. There is a gap between connecting base 3, which will not affect the rolling up of base plate 1. Base plate 1 can be rolled up for storage, which does not take up space and is convenient to use.

[0037] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solutions described in this invention, or by designing similar technical solutions by those skilled in the art under the inspiration of the technical solutions described in this invention, falls within the protection scope of this invention.
