Description

Technical Field

[0001] The utility model relates to the technical field of armrests, in particular to an infusion armrest. Background Art

[0002] Infusion refers to a large-dose injection solution infused into the body through intravenous drip. It is a branch of injections, usually packaged in glass or plastic infusion bottles or bags. When in use, the drip rate is adjusted through an infusion set, and the drug is continuously and stably infused into the body. Currently, in order to prevent the patient's arm from moving randomly or to improve comfort, an armrest is used to assist in supporting the patient's arm.

[0003] When the existing infusion armrest is in use, the armrest is generally of an integral design, resulting in a fixed length of the armrest, so that armrests of the same size cannot fit arms of different lengths, leading to a reduction in wearing comfort. For this reason, we propose an infusion armrest to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose an infusion armrest.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An infusion armrest includes an armrest main body. An adjusting mechanism is inserted into the armrest main body, and a support pad is fixedly connected to the surface of the adjusting mechanism. Binding mechanisms are fixed above the armrest main body and the adjusting mechanism, and limiting mechanisms are fixed on both sides of the armrest main body.

[0007] Preferably, the adjusting mechanism includes a telescopic support plate. The telescopic support plate is inserted into the armrest main body, and a fixed support plate is fixedly connected to the outer end of the telescopic support plate. By telescopic movement of the telescopic support plate in the armrest main body, the length between the armrest main body and the fixed support plate can be conveniently adjusted.

[0008] Preferably, a groove adapted to the telescopic support plate is opened inside the armrest main body, and the surface size of the fixed support plate is the same as the surface size of the armrest main body. By having the same surface size of the fixed support plate and the armrest main body, the function of limiting the telescopic support plate can be facilitated.

[0009] Preferably, the cross sections of the armrest main body, the telescopic support plate, and the fixed support plate are all arc-shaped. Connecting sliders are fixedly connected to both sides of one end of the telescopic support plate inserted into the groove, and through grooves adapted to the connecting sliders are opened on the inner wall of the groove. By setting the cross sections of the armrest main body, the telescopic support plate, and the fixed support plate to be arc-shaped, the degree of fit with the arm can be increased.

[0010] Preferably, the bundling mechanism includes a fixed block. Fixed blocks are fixedly connected to both upper sides of the armrest main body and the fixed support plate, and a bundling strap is connected above the fixed block. A magic tape is sewn on the surface of the bundling strap. By driving the magic tapes to adhere to each other with the bundling strap, the position between the armrest main body and the arm can be limited.

[0011] Preferably, the limiting mechanism includes a fixed frame. Fixed frames are fixedly connected to both sides of the armrest main body, and one end of a reset spring is welded to the inner wall of the fixed frame. The other end of the reset spring is welded to one side of a limiting disc, and the other side of the limiting disc is fixedly connected to a plugging column. A driving pull rod is inserted outside the fixed frame, and one end of the driving pull rod inserted into the fixed frame is fixedly connected to the limiting disc. By pulling the driving pull rod, the limiting disc and the plugging column can be telescopically moved in the fixed frame.

[0012] Preferably, the plugging column is arranged in a cylindrical shape. Through holes adapted to the plugging column are formed on the outside of the armrest main body, and a plurality of groups of grooves adapted to the plugging column are equidistantly formed on the side surface of the telescopic support plate. By arranging the plugging column in a cylindrical shape, the abrasion between the armrest main body and the telescopic support plate can be reduced.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The device can conveniently support the arm of an infusion patient through the armrest main body and the adjusting mechanism as a whole, and can lift the palm through the support pad, improving the infusion comfort. At the same time, by pulling the armrest main body, the armrest main body can slide along the surface of the telescopic support plate, so that the length between the armrest main body and the fixed support plate can be effectively and conveniently adjusted to adapt to arms of different lengths.

[0015] 2. The device can conveniently limit and connect the patient's arm and the armrest main body as a whole through the bundling mechanism fixed above the armrest main body and the fixed support plate. At the same time, through the elastic force of the reset spring itself, the limiting disc and the plugging column can be pushed to move, so that the plugging column can conveniently pass through the armrest main body and be inserted into the side surface of the telescopic support plate, effectively facilitating the limiting effect of the armrest main body and the telescopic support plate.
