Description

Technical Field

[0001] The utility model relates to the technical field of nursing chairs, in particular to a lower limb nursing chair. Background Art

[0002] In clinical practice, orthopedic patients need to change dressings frequently to accelerate healing. Medical staff check and change dressings on patients' wounds, which plays a vital role in promoting wound healing and preventing complications. When changing dressings, medical staff usually lift the patient's limbs or place them on temporary objects to fully expose the affected area. In this way, patients are usually required to take a comfortable position when changing dressings, and then multiple medical staff help to hold the affected limb to facilitate the doctor's dressing change. This method increases the burden on medical staff and increases labor intensity.

[0003] Most of the existing nursing chairs can support the patient's legs, making it easier for doctors to check wounds and apply medicine, but the supporting mechanisms mostly support both legs, and very few can support a single leg, which has low practicality. Therefore, we proposed a new nursing chair. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0026] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0027] In the related art, most of the supporting mechanisms support both legs, and very few can support a single leg, which has low practicality.

[0028] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a lower limb care chair. When it needs to be used, the amount of the plate body 14 to be lifted can be selected by simply rotating the lead screw 23 to adjust the position of the electric push rod 22.

[0029] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0030] Combination Figure 1-Figure 3 The embodiment of the present application provides a lower limb care chair, including a seat device 1; the seat device 1 includes: a backrest 12 is arranged on the top of a seat plate 11; a support mechanism 13 is arranged on the outer wall of the seat plate 11; a plate body 14 is arranged at the bottom of the seat plate 11 and is rotatably connected to the seat plate 11; an auxiliary component 2 is arranged at the bottom of the seat plate 11, and the auxiliary component 2 includes: a fixed seat 21 is arranged at the bottom of the seat plate 11; an electric push rod 22 is arranged on the outer wall of the fixed seat 21; a support block 231 is arranged at the bottom of the seat plate 11; a lead screw 23 passes through the fixed seat 21, the lead screw 23 is rotatably connected to the support block 231, and is threadedly connected to the fixed seat 21; a slide rail 25 is arranged at the bottom of the seat plate 11.

[0031] When in use, the plate body 14 for supporting the legs is set into two, and the lead screw 23 is rotated so that the fixing seat 21 threadedly connected to the lead screw 23 drives the electric push rod 22 to move on the slide rail 25, and the protruding end of the electric push rod 22 is aligned with the plate body 14 to be lifted, and then the top of the electric push rod 22 is used to lift the plate body 14, thereby lifting the patient's legs. The operation is simple and the patient can adjust it by himself.

[0032] Specifically, the electric push rod 22 is powered by an electric motor, and the rotational motion of the electric motor is converted into the linear motion of the push rod along the guide rail by means of gear reduction or a worm gear driving a lead screw nut, and the forward and reverse rotation of the electric motor is used to realize the reciprocating forward and backward motion of the push rod. The corresponding principle structure is not drawn in the attached drawings.

[0033] In some embodiments, the outer side wall of the plate body 14 is provided with a fixing groove 15. The setting of the fixing groove 15 can better facilitate the placement of the legs.

[0034] In some embodiments, a push rod 26 is disposed at the protruding end of the electric push rod 22. The arrangement of the push rod 26 can better push the two plates 14.

[0035] In some embodiments, a hand wheel 24 is provided at one end of the lead screw 23. The provision of the hand wheel 24 can better rotate the lead screw 23.

[0036] In some embodiments, a handle 241 is provided on the outer side wall of the hand wheel 24, and a fixed point mark is provided on the outer side wall of the hand wheel 24. The handle 241 can further increase the rotation mode of the hand wheel, and the fixed point mark on the hand wheel 24 can facilitate the patient to know the position to which the electric push rod 22 moves.

[0037] In some embodiments, a protective cover 27 is provided at the bottom of the seat plate 11, and the protective cover 27 contains the lead screw 23. The provision of the protective cover 27 can better protect the lead screw 23 from interference from other objects.

[0038] In some embodiments, the outer side wall of the seat plate 11 is provided with a protective cloth 17. The protective cloth 17 is used to cover the connection part between the seat plate 11 and the plate body 14.

[0039] In some embodiments, the bottom of the seat plate 11 is provided with a stopper 16 that matches the plate body 14. The stopper 16 is provided to prevent the plate body 14 from being too far back, causing the plate body 14 to be misaligned.

[0040] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification.

[0041] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.
