Description

Hemodialysis auxiliary nursing device

Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a hemodialysis auxiliary nursing device.

Background

Hemodialysis (HD) is one of the alternative treatments for the kidney of patients with acute and chronic renal failure. The method comprises the steps of draining blood in vivo to the outside of the body, enabling the blood and electrolyte solution (dialysate) with similar body concentration to be inside and outside one hollow fiber through a dialyzer consisting of a plurality of hollow fibers, and carrying out substance exchange through dispersion, ultrafiltration, adsorption and convection principles, so as to remove metabolic waste in the body and maintain the balance of electrolyte and acid and alkali; at the same time, the excess water in the body is removed, and the whole process of purified blood reinfusion is called hemodialysis.

In the hemodialysis process, a patient needs to lie on a simple bed for hemodialysis, and in the hemodialysis process, the patient cannot be effectively massaged and decompressed, so that the circulation of blood is promoted, and the efficiency of dialysis is reduced; and after patient's dialysis, often be the bedridden, need medical personnel to massage patient's shank to promote patient's blood circulation, prevent that shank limbs are stiff, walk after the influence, but nursing doctor operation process is wasted time and energy, and efficiency is slow, and working strength is high.

Disclosure of Invention

Aiming at the situation, in order to overcome the defects of the prior art, the invention provides the hemodialysis auxiliary nursing device, which effectively solves the problem of poor use effect of the conventional hemodialysis auxiliary nursing device.

In order to achieve the purpose, the invention adopts the following technical scheme: the hemodialysis auxiliary nursing device comprises a bed body, wherein a support plate is arranged on the bed body, a turnover plate is rotatably connected onto the support plate, and a turnover structure for driving the turnover plate to turn over along the support plate is arranged on the bed body; the bed body is also provided with massage devices corresponding to the supporting plate, each massage device comprises two lines of first massage structures for performing vibration massage on the legs, and the first massage structures are fixedly connected with the supporting plate; a massage cavity is fixedly connected to the bed body, a driving structure is connected in the massage cavity in a sliding manner, and the driving structure drives the first massage structure to carry out vibration massage on the legs in the sliding process; the two sides of the driving structure are both connected with a pair of second massage structures, the second massage structures are arranged on the two sides of the two rows of first massage structures, and each second massage structure comprises a massage rod which rotates along with the sliding process of the driving structure and moves up and down to massage the legs.

Compared with the prior art, the invention has the following beneficial effects:

1. when the patient lying bed is used, a patient lies on the supporting plate and the turnover plate, and the turnover plate is driven to turn over along the supporting plate through the turnover structure according to the condition of the patient, so that the patient is driven to be in a semi-lying position; the semi-supine position facilitates blood circulation, increases lung tidal volume and also relieves abdominal strain, making the patient comfortable.
