Abstract
The invention relates to a transfusion chair with a backrest angle adjusted by a ratchet, which comprises a chair frame and a seat cushion fixed on the chair frame; one end of the seat cushion is movably connected with the backrest and ratchet bars are arranged at the back of the backrest and provided with at least two tooth spaces from top to bottom; and supporting bars are movably arranged on the chair frame and selectively inserted in the tooth spaces of the ratchet bars. The transfusion chair is suitable for being used by hospital patients during transfusion, resting and nursing.
Description
Technical field
The present invention relates to technical field of medical, relate in particular to a kind of transfusion chair.
Background technology
Transfusion chair for hospital patient transfusion, have a rest and use during nursing.The structure of existing transfusion chair is: comprise the chair frame, be fixed with seat cushion on the chair frame, one end of seat cushion is fixed with backrest, fixedly connected (seat cushion that has and backrest are integral structure) by fixed angle between described backrest and the seat cushion, the transfusion chair that has in addition also comprises drip stand and the arm-rest frame that is fixed on the chair frame, is fixed on the compositions such as headrest on the backrest.The shortcoming of existing transfusion chair is: because the angle between seat cushion and the backrest is changeless, patient can only keep same sitting posture in long-time infusion process, can feel exhausted thus with uncomfortable.
Summary of the invention
Technical problem to be solved by this invention is: the transfusion chair that the backrest of angle adjustable between a kind of seat cushion and the backrest can be by the ratchet angle modulation is provided.
For addressing the above problem, the technical solution used in the present invention is: backrest can be by the transfusion chair of ratchet angle modulation, comprise the chair frame, be fixed with seat cushion on the chair frame, one end of seat cushion and backrest flexibly connect, and the back side of backrest is provided with ratchet bar, is provided with at least two teeth groove on the described ratchet bar from top to bottom, be movably set with support bar on the chair frame, described support bar optionally embeds in each teeth groove of ratchet bar.
Evenly be provided with nine teeth groove on the described ratchet bar from top to bottom.
Described backrest flexibly connects by an end of hinge and seat cushion.
Described support bar is the inverted U structure, and the two ends of support bar penetrate respectively and are arranged in the chair frame, also are provided with torsion spring in the junction of support bar and chair frame, and the middle part of support bar optionally embeds in each teeth groove of ratchet bar.
Also be fixed with drip stand and arm-rest frame on the described chair frame, also be fixed with headrest on the described backrest.
The invention has the beneficial effects as follows: above-mentioned backrest can be regulated backrest angle according to patient's clinical requirement by the transfusion chair of ratchet angle modulation, backrest is 100 °～180 ° with respect to the angle of regulation range of seat cushion, can be adjusted to flat prone position from general sitting posture, thereby efficiently solve patient in long-time infusion treatment process, the tired out and uncomfortable problem that causes because of sitting posture is unalterable.This transfusion chair backrest angle governor motion is simple in structure, cost performance is high, and is easy to adjust, quick, safe in utilization, reliable, inexpensive.

Fig. 3 is the structure for amplifying sketch map of A portion among Fig. 1;
Among the figure: 1, chair frame, 2, seat cushion, 3, swing hinge, 4, backrest, 5, ratchet bar, 6, support bar, 7, torsion spring, 8, drip stand, 9, arm-rest frame, 10, headrest.
The specific embodiment
Below by specific embodiment backrest of the present invention can be described in further detail by the transfusion chair of ratchet angle modulation.
As Fig. 1, shown in Figure 2, backrest can be by the transfusion chair of ratchet angle modulation, comprise chair frame 1, be fixed with seat cushion 2 on the chair frame 1, one end of seat cushion 2 flexibly connects by two swing hinges 3 and backrest 4, as shown in Figure 3, the back side of backrest 4 is provided with ratchet bar 5, evenly be provided with nine teeth groove on the described ratchet bar 5 from top to bottom, be movably set with support bar 6 on the chair frame 1, described support bar 6 is the inverted U structure, the two ends of support bar 6 penetrate respectively and are arranged in the chair frame 1, junction at support bar 6 and chair frame 1 also is provided with torsion spring 7, by the elastic force effect of this torsion spring 7, guarantee that support bar 6 can not break away from from the teeth groove of ratchet bar 5 under the situation of no external force effect, the middle part of support bar 6 optionally embeds in each teeth groove of ratchet bar 5, also be fixed with drip stand 8 and arm-rest frame 9 on the described chair frame 1, also be fixed with headrest 10 on the described backrest 4.
Operation principle of the present invention is: in support bar 6 embedding ratchet bars 5 teeth groove bottom, this moment, backrest 4 was (sitting posture) about 100 ° with respect to the angle of seat cushion 2; In support bar 6 embedded ratchet bar 5 teeth groove topmost, this moment, backrest 4 was (horizontal position) about 180 ° with respect to the angle of seat cushion 2; In like manner, support bar 6 embeds respectively in any one teeth groove in other seven teeth groove of ratchet bar 5, and then backrest 4 promptly is adjusted to a corresponding angle.The backrest 4 of this transfusion chair is 100 °～180 ° with respect to the angle of regulation range of seat cushion 2.
Operational approach of the present invention is:
A), a hands (A hands) catches the upper end of backrest 4, simultaneously, another hands (B hands) catches the upper end of support bar 6 to be pulled outwardly, thereby support bar 6 is broken away from from the teeth groove of ratchet bar 5, at this moment, the A hands should guarantee that backrest 4 does not descend automatically;
B), the A hands pulls backrest 4 up or down, making backrest 4 is after the center rotates to required angle, to unclamp the B hands with swing hinge 3, at this moment, support bar 6 can embed in the corresponding teeth groove of ratchet bar 5 under the elastic force effect of torsion spring 7 automatically, unclamps the A hands again and gets final product.
