Abstract

The utility model relates to an anti-bedsore mattress, which is suitable for long-term bed patients. The utility model is composed of plenum chambers, a mattress sleeve, a vent pipe, micro-air compressors, vent holes and a control circuit. The plenum chambers are two groups of hollow comb-shaped bodies which are arranged in parallel, the comb-shaped bodies are fixed in the mattress sleeve which is seamed by a piece of cloth, the comb-shaped bodies are respectively provided with a vent, the control circuit controls two micro-air compressors according to certain time to inflate or deflate two groups of plenum chambers in turn in order to make the plenum chambers expanded or contracted, and the contact zone of a mattress face and the patient body is changed in turn, which reaches the goal of preventing bedsore. The utility model is characterized in that the control circuit does not use electromagnetic valves, and therefore, the work noise is reduced.

Description

Anti-bedsore cotton-padded mattress

This utility model relates to a kind of Anti-bedsore cotton-padded mattress, is applicable to that the patient of long-term bed uses, and prevents to give birth to decubital ulcer, alleviates nursing staff's labor intensity.

Before this similarly comparatively complicated and some problem of the electrical control part in the inflated type Anti-bedsore cotton-padded mattress patent be in practice infeasible as: the electromagnetic valve that the control source of the gas is used.(noise during electromagnetic valve work and the heat radiation of electromagnetic valve coil are exactly a pair of contradiction, and reduce noise will influence heat radiation, because the noise of electromagnetic valve is sudden, therefore are difficult to allow the people accept in the ward of peacefulness, and the control circuit complexity).The interface in the plenum chamber too many (tens interfaces, so many interfaces air tight is not a thing easily, so poor reliability and cost are higher, present sick bed major part is that therefore the problem of these interfaces is just more for soft bed) and for example.

Feature of the present utility model is to overcome above-mentioned weak point of the prior art, provides a kind of: without electromagnetic valve, interface is few, control circuit is very simple, and automatic electronic Anti-bedsore cotton-padded mattress fully.

The purpose of this utility model be achieved in that it by: two groups of plenum chambers (A, B), bedding sack, breather, air vent, two micro-air compressors, control circuits are formed.The massage cotton-padded mattress is by bedding sack, and two groups of pectination plenum chamber (A that use the non-poromeric material of lamellar to make, B) form, two groups of pectination plenum chamber (A, B) increment direction is opposite, alternate, be arranged in parallel and insert in the bedding sack, they respectively have a blow vent, be connected with two micro-air compressors and two air vents respectively by breather, control circuit is according to alternative control micro-air compressor work of regular hour, just make two plenum chamber (A, B) alternately inflation or venting, promptly expand or stay, and then cause patient body heavy burden district alternately to change, reach ventilation, massage prevents to give birth to the purpose of decubital ulcer, alleviates nursery work intensity, and patient's misery.

This utility model advantage compared with prior art is: do not use electromagnetic valve, therefore just avoided the difficult problem of noise and heat radiation.Control circuit obtains simplifying simultaneously, and manufacturing cost is reduced greatly.The plenum chamber good integrity has reduced by tens interfaces and has also reduced manufacturing cost and improved reliability.

The drawing explanation of accompanying drawing:

Accompanying drawing 1 is a principle schematic of the present utility model, and Fig. 2 is the structural representation of bedding sack

Below in conjunction with accompanying drawing in detail this utility model is described in detail.

This utility model: Fig. 1 is its work principle figure, for convenience of explanation, and in the bedding sack among two groups of pectination plenum chambers (A, the B) Fig. 2 that do not pack among Fig. 1.Among Fig. 1: pectination plenum chamber (A, B) is hot-forming with double-deck " high-pressure polyethylene film ", (shape when among Fig. 1 being their unaerateds), Fig. 2 is a bedding sack, sew up with cloth, it by: (6), the cotton-padded mattress heart (7), cotton-padded mattress face (8), plastics thread gluing (9) are formed at the bottom of the cotton-padded mattress, its effect be the increment direction with two groups of pectination plenum chambers (A, B) opposite, alternate, be arranged in parallel and insert in the cotton-padded mattress heart (7), then the plastics thread gluing (9) of (6) at the bottom of cotton-padded mattress face (8) cotton-padded mattress is pasted mutually, it is sewed up in both sides, and (A, B) is fixed in the bedding sack with two groups of pectination plenum chambers.

Among Fig. 1: pectination plenum chamber (A, B) they respectively have a blow vent (1), breather (2) by separately links with two micro-air compressors (4) and two air vents (3), control circuit (5) is worked according to alternative two micro-air compressors (4) of controlling periodically respectively of regular hour, plenum chamber joining with it (A) or plenum chamber (B) are inflated, when plenum chamber (A) is inflated, air vent (3) venting of plenum chamber (B) by joining with it, air vent (3) venting of plenum chamber (A) when plenum chamber (B) is inflated by joining with it, just make pectination plenum chamber (A, B) alternative periodic expansion or contraction are worked so repeatedly, and then cause patient body heavy burden district alternately to change, can play massage to patient, ventilate, reach the purpose that prevents to give birth to decubital ulcer.

Air vent (3) is an air vent of never closing, and it is an aperture, and the area of section in hole should be less than 1 square millimeter.Hole big or small extremely important, it is the key that can cancel electromagnetic valve in the control circuit.The principle of this air vent is: the tolerance owing to output when micro-air compressor is worked is bigger, air vent has only very a spot of gas discharging, therefore can not influence inflation to plenum chamber, but after micro-air compressor quits work, because the gas of being deposited in the plenum chamber is very limited, though therefore but very little in minutes these gases being bled off of air vent is out of question, and the working cycle of massage cotton-padded mattress is very long again, approximately need 30 minutes, so the deflation time of a few minutes just can have been ignored.

Claims

A kind of Anti-bedsore cotton-padded mattress: it uses two groups of plenum chambers, bedding sack, breather, 2 micro-air compressors, control circuit,

It is characterized in that: it must use 2 micro-air compressors, do not use in control circuit that electromagnetic valve replaces it be: at the gas delivery port of two micro-air compressors to any part between the plenum chamber separately, each beats one or more apertures of never closing, the total area of section of these one or more apertures should be less than 1 square millimeter, these one or more apertures of never closing are exactly air vent illustrated in this utility model.
