Description

Technical Field

[0001] This invention relates to the field of critical care equipment technology, specifically to a nursing device for critically ill bedridden patients. Background Technology

[0002] Critically ill bedridden patients, especially those who have undergone cardiac surgery, bedside hemofiltration, or whose vital signs are unstable, require prolonged bed rest and should not be frequently moved or repositioned. During the care of these patients, to prevent pressure sores, promptly clean secretions, change bed linens, and perform local cleaning, it is necessary to moderately elevate the patient's body to facilitate these procedures, while simultaneously ensuring stable vital signs and minimizing nursing risks.

[0003] Currently, the lifting and care of critically ill bedridden patients in clinical practice mostly relies on manual handling or simple support tools. Manual handling requires the cooperation of multiple medical staff, and the operation is prone to causing fluctuations in the patient's position, affecting the stability of the patient's vital signs. Simple support tools are mostly fixed structures and cannot be flexibly adjusted according to the height of the bed, the patient's body shape, and the nursing scenario.

[0004] Therefore, there is an urgent need for a nursing device for critically ill bedridden patients to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a nursing device for critically ill bedridden patients, which effectively solves the problems of high risk of manual handling and poor adjustability of traditional support tools.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a nursing device for critically ill bedridden patients, comprising a lifting and adjusting base, a riser, a support rod, and a horizontal support mechanism. The riser is vertically mounted on the lifting and adjusting base, which drives the riser to rise and fall. The support rod is movably connected to the riser. An inclined support frame is installed on the riser, which supports the support rod and the riser and limits the movement of the support rod. The horizontal support mechanism is inserted into the support rod and includes a deployable and retractable scissor lift assembly.

[0007] Preferably, the lifting and adjusting base includes a chassis, an electric telescopic rod, and casters with brakes. The electric telescopic rod is embedded inside the chassis, and its output end is fixedly connected to the bottom of the riser. The casters are evenly distributed around the bottom of the chassis and fixedly connected to the chassis, used to drive the riser to lift and move and position the equipment.

[0008] When the above technical solution is adopted, the stable driving of the riser and the flexible movement and positioning of the equipment can be achieved by adjusting the lifting base.

[0009] Preferably, the riser is a cylindrical hollow structure, and a reserved groove is radially provided on the outer side wall of the top of the riser. The reserved groove penetrates the outer side wall of the top of the riser, and the connecting shaft is horizontally inserted into the reserved groove. The two ends of the connecting shaft are fixedly connected to the inner walls of the two sides of the reserved groove, respectively, for forming a movable connection with the support rod.

[0010] When the above technical solution is adopted, a stable movable connection between the support rod and the riser can be achieved by the cooperation of the connecting shaft and the reserved groove.

[0011] Preferably, a clamping frame is detachably installed on the outer side of the riser near the top by bolts. One end of the clamping frame is fixed to the outer wall of the riser, and the other end of the clamping frame is rotatably connected to one end of the inclined support frame. The other end of the inclined support frame has a through connecting screw hole.

[0012] When the above technical solution is adopted, the clamping frame enables a reliable connection between the inclined support frame and the vertical pipe, which facilitates the rotation and coordination of the inclined support frame.

[0013] Preferably, the support rod is a long, rigid structure. A through groove is provided on the side wall of the support rod along its length. The connecting shaft passes through the through groove and slides with it, thereby realizing the rotational and sliding connection between the support rod and the riser. One end of the support rod has a notch that matches the end of the inclined support frame. A threaded hole is provided on the side wall of the notch. A union bolt is threaded into the threaded hole. The union bolt is threaded with the connecting bolt hole to fix the inclined support frame and the support rod.

[0014] When the above technical solution is adopted, the inclined support frame and the support rod can be firmly fixed by the cooperation of the live bolt and the connecting screw hole.

[0015] Preferably, two spring plungers are symmetrically installed at the bottom of the through groove of the support rod, with the telescopic ends of the spring plungers set vertically upwards for positioning the horizontal support mechanism.

[0016] When the above technical solution is adopted, the horizontal support mechanism can be quickly engaged and positioned by means of a spring plunger.

[0017] Preferably, the horizontal support mechanism further includes a first crossbeam and a second crossbeam arranged in parallel. Both the first crossbeam and the second crossbeam are long, rigid structures. Limiting holes are provided on the side of the first crossbeam and the second crossbeam away from the scissor lift assembly, and the telescopic end of the spring plunger engages with the limiting hole.

[0018] When the above technical solution is adopted, the installation stability of the horizontal support mechanism is improved by the cooperation between the limiting hole and the spring plunger.

[0019] Preferably, the first crossbeam has a first groove along its length on the side near the scissor assembly, and the second crossbeam has a second groove along its length on the side near the scissor assembly. The scissor assembly consists of two cross-hinged connecting rods, and each connecting rod has a sliding shaft rotatably mounted at both ends. The sliding shafts are slidably connected to the first groove and the second groove, respectively, to realize the expansion and contraction of the horizontal support mechanism.

[0020] When the above technical solution is adopted, the horizontal support mechanism can be smoothly deployed and retracted through the cooperation of the sliding shaft and the sliding groove.

[0021] Preferably, both the first and second slides are T-shaped slides, and the two ends of the sliding shaft are provided with T-shaped sliders adapted to the T-shaped slides, and the T-shaped sliders slide in cooperation with the T-shaped slides; both ends of the first and second slides are provided with limiting protrusions to limit the movement stroke of the sliding shaft.

[0022] When the above technical solution is adopted, the T-shaped groove and the limiting protrusion can prevent the sliding shaft from coming out and limit its sliding stroke.

[0023] Preferably, both ends of the first and second crossbeams are provided with stepped grooves. The left end of the first crossbeam of one device is connected to the right end of the first crossbeam of another device through the stepped groove, and the left end of the second crossbeam of one device is connected to the right end of the second crossbeam of another device through the stepped groove, in order to expand the support area.

[0024] When the above technical solution is adopted, the first and second crossbeams of multiple devices can be spliced ​​together through the stepped groove, thereby expanding the overall support area.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention effectively solves the technical problems of high risks associated with manual handling and poor adaptability of traditional support tools in the care of critically ill bedridden patients by incorporating a lifting and adjusting base, upright tube, support rod, horizontal support mechanism, and inclined support frame. The invention utilizes a horizontal support mechanism that extends beneath the patient to provide lifting support, eliminating the need for multiple medical staff to manually move the patient. This avoids the problems of patient position fluctuations and instability of vital signs that can easily occur during manual handling, significantly reducing the risks of nursing operations. The lifting and adjusting base drives the upright tube to a certain height, and the movable connection structure between the support rod and the upright tube allows for flexible adjustment according to different bed heights and different nursing operation needs, overcoming the shortcomings of traditional support tools with fixed structures that cannot adapt to various usage scenarios. The inclined support frame provides support and limits to the support rod and upright tube, ensuring the stability and reliability of the overall support structure when lifting the patient. This allows the equipment to smoothly complete nursing operations such as bed unit replacement, secretion cleaning, local cleaning, and pressure ulcer prevention without frequent patient movement, significantly improving the adaptability and safety of the nursing equipment.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figures 1 to 10 As shown, the present invention provides a nursing device for critically ill bedridden patients, including a lifting and adjusting base 1, a vertical tube 2 installed on the top of the lifting and adjusting base 1, a support rod 3 movably inserted into the top of the vertical tube 2, and a horizontal support mechanism 4 horizontally inserted into the support rod 3.

[0030] The height adjustment base 1 is used to adjust the overall height of the riser 2 to accommodate beds of different heights; the support rod 3 can be unfolded on the riser 2 to form a stable support structure, which is used to extend under the patient's body and lift and move the patient smoothly off the bed; the horizontal support mechanism 4 is used to expand the support range, improve the safety and comfort of the support process, and facilitate medical staff to complete nursing operations such as bed unit replacement, local cleaning, and pressure ulcer prevention, avoiding fluctuations in the patient's position caused by manual movement.

[0031] The lifting and adjusting base 1 includes a chassis with universal wheels with brakes evenly distributed around the bottom of the chassis to facilitate flexible movement and precise positioning of the equipment; an electric telescopic rod is embedded inside the chassis, and the output end of the electric telescopic rod is fixedly connected to the riser 2. The telescopic rod is driven by an external power source to extend and retract, thereby enabling continuous height adjustment of the riser 2.

[0032] The riser 2 is a cylindrical hollow structure with a reserved groove 23 on the outer side of the top. A connecting shaft 24 is inserted into the reserved groove 23, and both ends of the connecting shaft 24 are fixed to the inner wall of the reserved groove 23. The inner diameter of the riser 2 matches the outer diameter of the support rod 3, and the support rod 3 can be vertically inserted into the inner cavity of the riser 2 to form a storage state.

[0033] A clamping frame 21 is detachably installed on the outside of the riser 2 by bolts. The end of the clamping frame 21 away from the riser 2 is rotatably connected to the inclined support frame 22. The end of the inclined support frame 22 away from the clamping frame 21 can fit into the notch 34 of the support rod 3 and is provided with a connecting screw hole 221 for cooperating with the support rod 3 to form a stable support.

[0034] The support rod 3 is a long, rigid structure with a long, through groove 33 on its side wall. The connecting shaft 24 passes through the through groove 33 to achieve a rotating and sliding connection between the support rod 3 and the riser 2. One end of the support rod 3 has a notch 34 that matches the inclined support frame 22. A live bolt 32 is threaded into the notch 34. The live bolt 32 can be threaded into the connecting screw hole 221 to lock and fix the inclined support frame 22 and the support rod 3, so that the support rod 3 and the riser 2 maintain a stable support state.

[0035] Two spring plungers 31 are installed at the bottom of the through groove 33 of the support rod 3 for quick positioning after the horizontal support mechanism 4 is inserted.

[0036] The horizontal support mechanism 4 includes a first crossbeam 41 and a second crossbeam 42 arranged in parallel. The first crossbeam 41 and the second crossbeam 42 are connected by a scissor assembly 43. The scissor assembly 43 consists of two cross-hinged connecting rods. Each connecting rod has a sliding shaft 431 rotatably mounted at both ends. The sliding shafts 431 at both ends of the same connecting rod are slidably connected to the first sliding groove 411 and the second sliding groove 421, respectively. The horizontal support mechanism 4 can be expanded and contracted by sliding the sliding shafts 431.

[0037] Both the first crossbar 41 and the second crossbar 42 have limiting holes 44 on the side away from the scissor lift assembly 43, which engage with the spring plunger 31 to achieve positioning.

[0038] In this embodiment, the device operates as follows: Pull out the support rod 3 from the riser 2, rotate it 90 degrees clockwise along the connecting shaft 24 so that the support rod 3 and the riser 2 are in a right-angle support state. Push the support rod 3 to the appropriate position along the connecting shaft 24 through the through groove 33. Flip up the inclined support frame 22 and make its end fit into the notch 34 of the support rod 3. Tighten the swivel bolt 32 so that the swivel bolt 32 and the connecting screw hole 221 are engaged to complete the fixation. Activate the lifting and adjusting base 1, and adjust the riser 2 to a height that matches the hospital bed; Pull the first crossbar 41 and the second crossbar 42 to unfold the scissor lift assembly 43, insert the horizontal support mechanism 4 into the through groove 33 of the support rod 3, and make the spring plunger 31 engage with the limiting hole 44 to complete the positioning. Push the equipment to the bedside, lock the casters, and allow the horizontal support mechanism 4 to smoothly extend under the patient's body; Activate the lifting and adjusting base 1 to raise the upright tube 2, which will help to lift the patient smoothly off the bed, allowing medical staff to carry out nursing procedures; After the nursing care is completed, the patient is gently placed back on the bed, the equipment is removed, the horizontal support mechanism 4 is retracted, the union bolt 32 is loosened, the support rod 3 is pulled along the connecting shaft 24 through the through groove 33, and then rotated counterclockwise by ninety degrees to make the support rod 3 coaxial with the riser 2, and pushed into the inner cavity of the riser 2 to complete the storage.

[0039] like Figure 5 , Figure 6 and Figure 10 As shown, in other embodiments, the sliding structure and extension structure of the horizontal support mechanism 4 are optimized.

[0040] Both the first slide groove 411 and the second slide groove 421 are T-shaped slide groove structures. The upper and lower ends of the sliding shaft 431 are provided with T-shaped sliders that match the T-shaped slide grooves. The T-shaped sliders slide in conjunction with the T-shaped slide grooves to prevent the sliding shaft 431 from disengaging from the slide grooves.

[0041] Both ends of the first slide groove 411 and the second slide groove 421 are provided with limiting protrusions to limit the maximum displacement of the sliding shaft 431 and prevent the scissor assembly 43 from being over-extended.

[0042] In this embodiment, the unfolding and retraction operation process of the horizontal support mechanism 4 is as follows: Pulling the first crossbar 41 and the second crossbar 42 in the opposite direction causes the T-shaped slider of the sliding shaft 431 to slide smoothly along the T-shaped groove, and the scissor assembly 43 to slowly unfold until the sliding shaft 431 abuts against the limiting protrusion, reaching the maximum safe unfolding width. Insert the horizontal support mechanism 4 into the through groove 33 of the support rod 3, and the spring plunger 31 is engaged in the limiting hole 44 to complete the positioning. When retracted, the first crossbar 41 and the second crossbar 42 are squeezed in the opposite direction, the scissor assembly 43 retracts, the limiting hole 44 disengages from the spring plunger 31, and the sliding shaft 431 drives the T-shaped slider back to the initial position, achieving stable retraction.

[0043] Both ends of the first crossbeam 41 and the second crossbeam 42 are provided with step grooves 45. The left end of the first crossbeam 41 of one device can be spliced ​​with the right end of the first crossbeam 41 of another device through the step grooves 45. The same applies to the second crossbeam 42. Splicing multiple devices can expand the overall support area, which is suitable for patients with larger body sizes.

[0044] like Figure 3 , Figure 7 and Figure 8 As shown, in other embodiments, the positioning structure of the support rod 3 and the inclined support frame 22 is optimized.

[0045] The support rod 3 has a limiting step inside the notch 34. The limiting step fits snugly with the end of the inclined support frame 22 away from the clamping frame 21. The head of the live bolt 32 has a through hole, which can be rotated with a simple rod-shaped tool, reducing the difficulty of operation for medical staff.

[0046] In this embodiment, the unfolding and retracting operation process of the support rod 3 is as follows: When unfolding, the support rod 3 is vertically pulled out from the riser 2 and rotated 90 degrees clockwise along the connecting shaft 24. The support rod 3 is pushed laterally to the appropriate position along the connecting shaft 24 through the through groove 33. The end of the inclined support frame 22 is aligned with the limiting step of the notch 34. A simple rod-shaped tool is used to pass through the through hole of the head of the live bolt 32 and tighten the live bolt 32 with the connecting screw hole 221. Under the limiting step, the support rod 3 and the riser 2 are kept in a precise vertical support state. When storing, use a simple rod-shaped tool to loosen the slip bolt 32, disconnect the inclined support frame 22 from the support rod 3, pull the support rod 3 horizontally along the connecting shaft 24 through the through groove 33, then rotate the support rod 3 counterclockwise 90 degrees along the connecting shaft 24 to make the support rod 3 coaxial with the riser 2, and finally push the support rod 3 into the inner cavity of the riser 2 to complete the storage. At this time, the end of the support rod 3 with the notch 34 is exposed on the outside of the riser 2 for easy operation next time.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
