Description

Technical Field

[0001] This invention belongs to the field of medical and nursing technology, and specifically relates to a nursing device for patients with severe delirium. Background Technology

[0002] Common clinical manifestations of delirium include: altered consciousness, confusion, decreased memory, orientation, and attention, irregular sleep-wake cycles, and sensory disturbances. Symptoms fluctuate, being more severe during the day and milder at night. Current medical care for delirium primarily includes: establishing regular lifestyle habits, reducing daytime sleep, and limiting water intake and avoiding strong tea and coffee before bedtime.

[0003] To provide more effective care for patients with severe delirium, medical staff can use the following methods: 1. Family members can record messages (in their local dialect) and tell the patient the exact time, date, location, and even the reason four times a day. 2. A simulated sky and sunlight screen can be installed above the patient's bed to simulate the sky and sunlight conditions according to the daily diurnal rhythm, allowing the patient to see it.

[0004] However, traditional nursing care generally focuses more on symptom relief. When a patient experiences a seizure, restraints are used to control the patient and prevent agitation leading to self-harm or harm to medical staff. Effectively preventing patients from falling out of bed during agitation remains a technical challenge for healthcare professionals. Furthermore, the presence of bed rails or curtains can exacerbate fear in some patients, potentially triggering a seizure. Therefore, it is essential to design an assistive nursing device to address the aforementioned problems encountered in caring for patients with delirium. Summary of the Invention

Correspondingly, the second slide rail rod is provided with a through hole adapted to allow the first transmission rod to pass through.

[0010] Preferably, the side end of the slide rod is provided with a limiting groove, and correspondingly, the side end of the slide groove is provided with a limiting protrusion that matches the limiting groove.

[0011] Preferably, the first driving mechanism further includes a second elastic element, a positioning rod, and an extension plate. The upper end of the fixed column is provided with a receiving groove, and the extension plate is fixedly disposed at the opening of the receiving groove. The lower end of the positioning rod is fixed to the bottom of the receiving groove.

[0027] 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.

[0028] like Figures 1-6As shown, a nursing device for a patient with severe delirium includes a support plate 1 for the patient to lie on, a railing 11, a fixing post 12, a telescopic rod 13, a first drive mechanism for tilting the railing 11 upwards away from the patient, and a second drive mechanism for driving the support plate 1 to move downwards synchronously when the railing 11 moves; the side ends of the railing 11 and the side ends of the support plate 1 are slidably connected in the vertical direction; the telescopic rod 13 is hollow inside and fixed at one end to the fixing post 12, and the other end is fixed to the lower end of the support plate 1; the first drive mechanism includes a first transmission rod 19, a fixing seat 21, a first connecting rod 240, a buffer, a second connecting rod 25, a transmission plate 26, a first transmission wheel 281, a first slide rail 29, and a slide rod 28; one end of the first transmission rod 19 is rotatably connected to the lower end of the railing 11, and the other end is rotatably connected to the fixing seat 21; the first connecting rod 25 is slidably connected to the support plate 11, the second connecting rod 26, the second connecting rod 27, the third connecting rod 28, the fourth connecting rod 29, the fifth connecting rod 28, the sixth connecting rod 29, the seventh connecting rod 29, the eleventh ... One end of the connecting rod 240 is fixed to the fixed column 12, and the other end is buffered and connected to the fixed seat 21 through a buffer member; one end of the second connecting rod 25 is fixed to the fixed seat 21, and the other end is fixed to the transmission plate 26. The end of the transmission plate 26 facing away from the second connecting rod 25 is provided with a first transmission tooth 270; the first transmission wheel 281 is rotatably disposed on one side of the first slide rail 29, and the slide rod 28 is slidably disposed on the first slide rail 29, and the slide rod 28 is provided with a second transmission tooth. The two sides of the first transmission wheel 281 are respectively engaged with the first transmission tooth 270 and the second transmission tooth for transmission. Correspondingly, the first slide rail 29 is provided with a sliding groove for the slide rod 28 to slide. The side of the sliding groove near the first transmission wheel 281 is provided with a through groove for the second transmission tooth to be exposed and engaged with the first transmission wheel 281. The end of the slide rod 28 facing away from the first slide rail 29 is rotatably connected to the side of the guardrail 11 away from the support plate 1.

[0029] In this embodiment, the patient can lie on the support plate 1, which is supported by the telescopic rod 13. In practical applications, the telescopic rod 13 can be a high-friction rod to support the patient's weight and prevent them from falling off, or it can be a nut-fastening rod installed on the side of the fixed column 12, which is further tightened by rotation to achieve fixation. However, the fixation of the telescopic rod 13 is not rigid; it can be driven to sink by applying force to the support plate 1 through the second drive mechanism. In practical applications, medical staff can adjust the mechanism according to each patient's weight. When the patient's condition worsens and they roll towards the railing 11, the first transmission rod 19 moves downward under force, causing the fixed seat 21 to move downward. Simultaneously, as the transmission plate moves downward, it drives the first transmission wheel 281 to rotate, and the first transmission wheel 281 drives the sliding rod 28 meshing with it to move upward, thus lifting the upper end of the railing side upward. Therefore, when the patient rolls to the side of the railing, it acts as a barrier, preventing the patient from falling out of bed. Although the above-mentioned limit specifies that the guardrail 11 and the support plate 1 are slidably connected in the vertical direction, when the guardrail 11 is subjected to force, it will inevitably flip to one side towards the support plate 1. This is possible because the horizontal direction of the guardrail 11 and the support plate 1 is not restricted.

[0030] The first slide rail rod 29 is not shown in the figure in terms of how its end is fixed. In actual application, its end can be directly fixed to the fixed column 12 or the ground, as long as the first transmission wheel 281 and the transmission plate can be pressed together to achieve meshing transmission.

[0031] like Figure 2 As shown, the buffer includes a sliding ring 24, a first elastic element 22, and a sliding column 23. The sliding ring 24 is fixedly disposed on the side of the first connecting rod 240 facing away from the fixed column 12. The sliding column 23 is fixedly disposed below the fixed seat 21. The first elastic element 22 is sleeved on the outside of the sliding column 23 and located between the sliding ring 24 and the fixed seat 21. The sliding column 23 is slidably disposed in the hollow part of the sliding ring 24. When the fixed seat 21 moves downward, the sliding column 23 can slide within the sliding ring 24, while the first elastic element 22 provides a restoring force when the fixed seat 21 is not under force, causing it to return to its original position.

[0032] In this embodiment, the first driving mechanism further includes a second slide rail 18. One end of the second slide rail 18 is elastically rotatably connected to the fixed column 12, and the other end is slidably connected to the first transmission rod 19. Correspondingly, the second slide rail 18 is provided with a through hole adapted to allow the first transmission rod 19 to pass through.

[0033] To make the connection of the slide rod 28 in the slide groove more secure, the side end of the slide rod 28 is provided with a limiting groove 280, and correspondingly, the side end of the slide groove is provided with a limiting protrusion that matches the limiting groove 280.

[0034] like Figure 6 As shown, the first driving mechanism also includes a second elastic element 30, a positioning rod 15, and an extension plate 14. The upper end of the fixed column 12 is provided with a receiving groove, and the extension plate 14 is fixedly installed at the opening of the receiving groove. The lower end of the positioning rod 15 is fixed to the bottom of the receiving groove. The first slide rail rod 18 is provided with a through hole, and the positioning rod 15 is slidably inserted through the hollow part of the through hole. The second elastic element 30 is sleeved on the positioning rod 15, and one end of the second elastic element 30 abuts against the lower end of the first slide rail rod 18, and the other end abuts against the bottom of the receiving groove.

[0035] In this embodiment, the second driving mechanism includes a traction rope 20, a guide wheel 17, and a guide wheel rotating seat 16. The upper end of the telescopic rod 13 has a first through hole, and the lower end of the fixed column 12 has a second through hole. One end of the traction rope 20 is fixed to the lower end of the support plate 1 and wrapped around the guide wheel 17. The other end passes through the first through hole and the second through hole in sequence and is fixed to the fixed seat 21. The guide wheel 17 is rotatably mounted on the guide wheel rotating seat 16. When the fixed seat 21 moves downward, it pulls the traction rope, causing it to pull the support plate 1 downward, thereby creating a depression in the support plate 1 in the middle of the patient's lying position, which can further prevent the patient from falling out of bed.

[0036] In this embodiment, the second drive mechanism further includes a torsion spring, one end of which is fixed to the guide wheel 17, and the other end is fixed to the guide wheel rotating seat 16. The torsion spring serves to hold the rope in place and keep it taut at all times.

[0037] like Figure 3 As shown, the first transmission rod 19 is set at an angle, and correspondingly, the through hole is also set at an angle.

[0038] To improve patient comfort and avoid unevenness at the connection between the support plate 1 and the railing 11, the support plate 1 is provided with an arc-shaped contact part on the side near the railing 11.

[0039] To simulate the sky and sunlight conditions according to the daily diurnal rhythm, a sunlight simulation screen is installed above the patient's bed so that the patient can see it.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
