Description

Technical Field

[0001] The invention belongs to the technical field of postoperative rehabilitation facilities, and in particular relates to a cardiac surgery rehabilitation nursing bed. Background Art

[0002] Cardiac surgery nursing beds play a vital role in the medical field. They can not only provide better medical care for patients in the early stages of recovery and reduce the pressure on patients' families, but also lay the foundation for the patient's later recovery. The design of this nursing bed takes into account the various needs of patients, among which angle adjustment is crucial. The angle adjustment mechanism can enable patients to maintain a suitable position to promote recovery. It helps to improve the quality of life and satisfaction of patients by providing professional nursing support, while also improving the efficiency and effectiveness of medical care.

[0003] The existing nursing beds only allow the patient to change from a lying position to a sitting position by bending the bed board. When the bed board is bent, the patient's feet and buttocks are not properly supported, and the patient will slide when sitting up with the bed board bending. At this time, the patient will use his own force to overcome the sliding. In this case, the patient's wound will split, which is not conducive to the patient's recovery. In addition, due to the curved nursing bed structure, when the patient sits up, the patient's legs are still flat, which will make the patient's legs uncomfortable and in a straight state, and it is not convenient for the patient to walk directly from a sitting position.

DETAILED DESCRIPTION

[0029] The present invention discloses a cardiac surgery rehabilitation nursing bed, such as Figure 1 and Figure 2 As shown, it includes a bed board 1, and two pairs of rotating supports 2 are provided at the bottom of the bed board 1. The rotating supports 2 include a bottom shaft 21 fixed to the bottom of the bed board 1 and supporting feet 22 rotatably arranged on the bottom shaft 21, one of which is located at the head end of the bed board 1, and the bottom end of the supporting feet 22 of the other rotating support 2 is fixed to the ground, and a telescopic cylinder 3 is also obliquely fixed on the ground, and a wheel 31 is provided at the end of the telescopic cylinder 3, and the wheel 31 is rotatably arranged at the bottom of the bed board 1; as shown Figure 5 and Figure 7 As shown, the telescopic cylinder 3 is extended to rotate the bed board 1 around the rotating support 2 fixed to the ground by the supporting foot 22. A transverse telescopic rod 4 is fixedly provided on one side of the head end of the bed board 1. A seat board 5 is provided at the end of the transverse telescopic rod 4. When the transverse telescopic rod 4 extends the seat board 5, the seat board 5 is located at the tail end of the bed board 1. When the transverse telescopic rod 4 retracts the seat board 5, the seat board 5 moves to the middle of the bed board 1. As the bed board 1 rotates, the buttocks position of the patient lying horizontally on the bed board 1 is supported.

[0030] When the telescopic cylinder 3 is retracted, the nursing bed is supported by the supporting feet 22 of the two pairs of rotating supports 2 to maintain a horizontal state, and is used for patients to lie down and rest. A soft cushion can be laid flat on the bed board 1 to ensure the comfort of the patient. When the patient needs to change from a lying position to a sitting position, the seat board 5 moves slowly from the patient's foot end through the retraction of the telescopic cylinder 3. As the patient's legs are lifted, the seat board 5 is supported and blocked at the patient's hip position. At this time, the telescopic cylinder 3 is extended to rotate the bed board 1 to Figure 7 During the rotation of the bed board 1, the seat board 5 always supports the patient's buttocks, and the bed board 1 always supports the patient's back, so that the patient can change from a lying position to a sitting position in a relatively comfortable state. During the rotation of the bed board 1, the patient's calves naturally droop and finally touch the ground. When the nursing bed is in a sitting state, the patient can keep his calves drooping, and the buttocks and back are supported. Compared with an ordinary curved nursing bed, the patient can only lift his upper body as the bed board 1 bends, and the legs still remain flat. The sitting state of this nursing bed is more comfortable, which is convenient for the patient to exert force to stand up or perform other self-actions in a sitting state.

[0031] In a further solution, Figure 3 and Fig. 9 As shown, the transverse telescopic rod 4 includes a fixed cylinder 41, which is fixed above the side edge of the bed board 1. The fixed cylinder 41 can be used as a protective structure for the edge of the bed board 1. An extension rod 42 with a square cross-section is slidably provided inside the fixed cylinder 41. A strip groove 421 and a rack 422 are respectively extended in the same direction on the extension rod 42. A sliding pin 411 and a motor 412 are provided inside the end of the fixed cylinder 41. A gear 413 meshing with the rack 422 is provided at the end of the motor 412. The sliding pin 411 is slidably set in the strip groove 421. A positioning rod 11 is also provided at the side edge of the bed board 1. A sliding hole is provided on the positioning rod 11. The extension rod 42 slides through the sliding hole. An elastic fixing pin 12 is provided on the inner side of the sliding hole. The telescopic rod extends into the side of the end of the extension rod 42 and is provided with a pin hole 423. When the extension rod 42 is recovered, the elastic fixing pin 12 is stuck in the pin hole 423.

[0032] In this structure, the gear 413 is driven to rotate by the motor 412, and the gear 413 drives the rack 422 to move, so that the entire extension rod 42 moves, and under the limitation of the sliding pin 411 and the bar groove 421, the extension rod 42 can ensure smooth and horizontal movement. The transverse telescopic rod 4 of this structure has a simple structure, a long extension and recovery distance, and a smooth and stable extension and retraction, which avoids bumps and injuries to the patient. Furthermore, by setting a positioning rod 11, the elastic fixing pin 12 in the positioning rod 11 is inserted into the pin hole 423 when the extension rod 42 is recovered to the supporting state of the seat board 5, so as to support and limit the movement of the extension rod 42. When the seat board 5 supports the patient, the seat board 5 is supported by the positioning rod 11 to avoid sliding of the extension rod 42 and ensure the support stability of the seat board 5.

[0033] In a further solution, Figure 8 As shown, an electric cylinder 13 is fixedly provided on the positioning rod 11, and a connecting column 14 is provided at the end of the electric cylinder 13. The connecting column 14 is fixedly connected to the elastic fixing pin 12 inside the positioning rod 11. When the electric cylinder 13 is recovered, it drives the elastic fixing pin 12 to move out of the pin hole 423.

[0034] This structure can quickly move the elastic fixing pin 12 by setting a connecting column 14 structure driven by an electric cylinder 13. This structure is used to uniformly move a plurality of elastic fixing pins 12 so that the elastic fixing pins 12 move out of the pin holes 423 of the extension rod 42. At this time, the extension rod 42 can be moved again under the drive of the motor 412 to ensure the return of the seat plate 5.

[0035] In a further solution, Figure 2 and Fig.10 As shown, there are two transverse telescopic rods 4 and they are arranged in parallel up and down, wherein a support shaft 51 is provided at the end of the lower extension rod 42, and the support shaft 51 is rotatably set on the bottom side of the end of the seat plate 5, and a support roller 52 is provided at the end of the upper extension rod 42, and the support roller 52 is rollingly supported and set on the bottom side of the seat plate 5. When the seat plate 5 is used for recovery support, the upper and lower extension rods 42 are staggered to make the seat plate 5 inclined.

[0036] In this structure, two transverse telescopic rods 4 are set, and two transverse telescopic cylinders 3 provide support shafts 51 and support rollers 52. Under the support of the support shafts 51 and support rollers 52, the supporting capacity of the seat 5 is ensured, and the transverse telescopic rods 4 with different extension lengths are provided to change the inclination angle of the seat 5. In the process of the seat 5 being retracted and supported on the patient's buttocks, the seat 5 selects a larger inclination angle, and the seat 5 can slowly and comfortably lift the patient's legs at an acute angle to ensure the patient's comfort. When the seat 5 reaches and supports the patient's buttocks, the seat 5 rotates to a sitting angle.

[0037] In a further solution, Fig.10 As shown, the outer edge of the seat board 5 is also slidably provided with a plurality of sliding rods 53, and an elastic pin structure can be arranged inside the sliding rods 53 and the seat board 5, and a round stick 54 is fixedly arranged at the ends of the plurality of sliding rods 53. By arranging the retractable round stick 54, it can adapt to patients with different thigh lengths and further improve the sitting comfort of the patients.

[0038] In a further solution, Figure 1 , Figure 4 and Figure 5As shown, the bed board 1 is also hinged with a foot end board 6 at the tail end, and also includes a double-ended pin 61. Fixing holes are respectively provided on the side of the foot end board 6 and the side of the hinge shaft. The double-ended pin 61 is inserted into the two fixing holes. Before the bed board 1 is tilted and rotated, the double-ended pin 61 slides out of the fixing hole. When the bed board 1 is rotated to a sitting position, the foot end board 6 is supported on the ground.

[0039] In this structure, by setting the foot end plate 6, the lying length of the bed board 1 can be extended, and the patient's lying comfort can be improved. The bed board 1 and the foot end plate 6 are supported and fixed by the double-headed pin 61; and in the sitting state, the foot end plate 6 is rotated and supported on the ground to support the patient's feet. When the patient is not wearing shoes, the patient's feet will not directly touch the ground, thereby ensuring the patient's hygienic state and further improving the patient's comfort.

[0040] In a further solution, Figure 5 and Figure 6 As shown, it also includes a foot end support column 7, the foot end support column 7 is fixed to the ground, the upper end of the foot end support column 7 is rotatably provided with a baffle 71, the rotation axis of the baffle 71 is parallel to the ground, the upper end of the foot end support column 7 is provided with a baffle 72, the baffle 72 is blocked at the lower side of the baffle 71, so that the baffle 71 is parallel to the ground, and the baffle 71 supports the bottom side of the end of the foot end plate 6 when it is in a horizontal state.

[0041] By setting the foot end support column 7, when the bed board 1 rotates from a lying state to a sitting state, the foot end plate 6 rotates upward under the blocking of the stop bar 71 and moves out of the supporting position of the foot end support column 7, and finally moves to the foot support state of the sitting state. When the bed board 1 rotates from a sitting state to a lying state, the foot end plate 6 rotates downward under the action of gravity and rotates to the stop bar 71. The stop bar 71 is forced to rotate upward. When the bed board 1 is horizontal, the foot end plate 6 is manually rotated upward again and put down, and the foot end plate 6 is supported by the stop bar 71.

[0042] In a further solution, Figure 1 As shown, a side of the bed board 1 where the transverse telescopic rod 4 is not provided is provided with a guardrail 8, and the guardrail 8 is rotatably provided at the side edge of the bed board 1. The provision of the guardrail 8 can ensure the safety of the patient, and after the rotatable guardrail 8 is opened, it can also ensure that the patient can directly sit up and get out of the bed from the lying state on the bed board 1.

[0043] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
