Abstract

In the clinical nursing activity, the most common complication is 'bedsore'. Especially, the patient who stupefies, lies in bed for a long term or is forced to lie in bed and can not or is prohibited to turn over is easy to cause the inflammation and live the sore because the human body contacts with the bed during a long time and the ventilation property is poor. Simultaneously the sore brings very large difficulty in the nursing service. The 'bedsore' not only brings bitter and pain for the patient, but also brings direct cause of death. The utility model provides a bedsore-proof bed which adopts machinery (or electric control) structure to drive the honeycomb slat and constitute the bed surface. The bed surface can make alternating motion upwards and downwards, and causes the human body to generate void with the bed contact face. The utility model enhances the blood circulation of the human body and achieves the aim of bedsore preventing.

Description

Bedsore-proof bed

This utility model belongs to a kind of attached field of medical that helps that anti-decubital ulcer is given in the unknown: relate to a kind of mechanical activity bed that a kind of patient that can help long-term bed prevents to produce decubital ulcer more specifically.

In family or hospital, often some patient since certain cause of disease to long-term bed is not risen, also some patient is because treatment need force clinostatism to stand up, human body is long with the time of bed contact surface, breathability is poor, easily causes the living skin ulcer of inflammation.So in clinical nursing activity, bring greatest difficulty to the nurse, modal nursing complication is exactly " decubital ulcer ".Heavy physical work of nurse is not only in the nursing of decubital ulcer, and the lighter to patient bring add on the hardship pain, weight person be cause death immediate cause.

The purpose of this utility model provides a kind of nurse's of alleviating labor intensity, prevents a kind of device bed of decubital ulcer.

According to the pathogenic factor of decubital ulcer, this utility model adopts the pectination batten and the bed surface that constitutes.Its bed surface can move up and down, and alternately contacts patient's pressurized position, make it ventilated, thereby blood circulation promoting prevents the generation of decubital ulcer.

This utility model mainly adopts frame for movement or the electrical equipment structure that combines with machinery.12 groups of (or eight groups or ten groups or 14 groups) pectination batten bed surface and connecting rod links are installed on its long axis component, and as shown in Figure 1, under the effect of swing arm, connecting rod drives the bed surface that the pectination batten constitutes, and does up-down alternative motion.When swing arm was in a left side or right about 46 ° of positions, the clamp in the swing arm was located automatically, its six (or four or five or seven) pectination batten displacements is raise support patient bodies; And other six (or four or five or seven) pectination batten displacements descend, and produce the space, and when swing arm was in the centre position, then 12 blocks (or eight or ten or 14) pectination battens became a recessed slightly plane.Make patient body all contact bed surface, lift for making patient's upper body, internal crucible is provided with the movable bed frame that lifts about 30 °.

With rocking handle rotation crank axle, screw promotes leading screw and four groups of universal joints, and movable bed frame is lifted, and move as needing the rotation swing arm should make the pectination bed surface do alternatively up and down this moment.In the position that is positioned at the human buttock, be provided with an activity pectination batten, it is fallen down form about 385 square centimeters space, be convenient to patient-sized usefulness just.Be laid with cushion above the pectination batten, make patient feel soft comfortable.

Its project organization of this utility model is reasonable, operation, easy to use; Can satisfy patient and equal multiple postures such as crouching and rise and retire, and make things convenient for patient-sized just to wait characteristics.

Accompanying drawing:

Fig. 1 is the antidecubitus beds general assembly drawing.

Fig. 2 is the profile of major axis (5).

Fig. 3 is the profile of pectination batten (4).

Fig. 4 is the electric control block diagram.

Provide embodiment below in conjunction with accompanying drawing 1, accompanying drawing 2, accompanying drawing 3:

Accompanying drawing 1 is a general assembly drawing: by head of a bed assembly (1), and fixed bedstead assembly (2), movable bed frame assembly (3), pectination bar board component (4), major axis link assembly (5), swing arm assembly (6), spacing ring (003), and folding (001), the binding of standard components such as screw combines.When removing pressure swing arm handle with hands, lift by steel wire and lever clamp the swing arm lower end, swing arm and spacing ring (003) are thrown off, can move swing arm to the left or to the right, drive major axis link assembly (5) by swing arm and rotate, make the connecting rod (510) that bends and stretches that is connected with pectination bar board component (4) do flexion and extension, make six six volts of 12 groups of (or other group numbers) pectination battens, the pectination batten of projection supports patient body, and recessed generation space can be ventilated.

Totally ten two (or eight or ten or 14) right-hand members of pectination bar board component (4) and middle with folding (001) binding; Left end is with a guide groove and bedside location-plate (002) slippage.Foam plastics or sponge are laid in pectination bar board component top, or other soft pads (401) are with cloth or use plastics, and perhaps other material packages rise, and it is soft comfortable that contact patients is felt.

Fig. 2 is the major axis profile.It is by crank shaft (501), hold-down nut (502), and screw mandrel (503), screw (504), four groups of universal joints (505), directed axle sleeve (506), long sleeve pipe (507), (parts such as 509 are formed for bearing block (508) and long pin.Swing arm (6) links to each other with long sleeve pipe (507) with nut (502), and universal joint (505) first three groups links with dump bolt, and the back uses long pin (509) to link for one group.Long pin (509) can be slided in two guide grooves in directed axle sleeve (506), when swing arm is rotated, drives whole major axis like this, promptly drives 12 groups and bends and stretches connecting rod and do flexion and extension.Lifting of movable bed frame is to rotate by crank shaft (501).Drive screw mandrel (503) by screw (504) and pass forward, promote movable bed frame by universal joint and lift.

Be provided with a pectination batten in the position that is positioned at patient posterior, when rotating lever unclamps pressing plate, can fall down automatically, about 385 square centimeters space appears in the buttocks below, is convenient to the usefulness of patient's defecation.

Head of a bed assembly (1) is to bend with metal material to be welded, and is similar to common bed.Two bedside of fixed bedstead (2) are to be bent into metal material

Shape, movable bed frame (3) is connected with fixed bedstead (2) by rotating shaft, and can lift the angle about 30 °.

Fig. 4 is the electric control block diagram.(I) is timing system among the figure, and (II) is automatic control system, and (III) is motor drive mechanism, and (IV) is electronic and the mechanical hinge system.

The utility model can also be used except adopting whole frame for movements, by timing system control or auto-controlled motor and mechanical hinge, carries out automatically or semiautomatic control, makes 12 groups of pectination batten up-down alternative motions.
