Description

Mattress formula Multifunctional defecating bed chair

Technical field

This utility model relates to a kind of mattress formula Multifunctional defecating bed chair, belongs to nursing bed accessory class.

Background technology

The patient that long-term bed etc. can not stand up to take care of oneself needs to carry out special nurse, because patient can not always lay flat on one's back, need to prop up every now and then health and change posture rest, or prop up defecation etc., and these all will expend a large amount of muscle power of nurse personnel.To this, have in the market nursing bed, the nursing wheelchair etc. of a lot of various structures, but they all have defect.For example: wheelchair (comprise with toilet seat structure) is only suitable for the patient that the state of an illness is light, can adapt to long-time sitting posture, and patient body is gently important, if patient is because of long-term bed overweight, may be from bed → wheelchair → bed → wheelchair ... move continually, therefore the use of wheelchair has a lot of limitation.Existing conventional nursing bed roughly divides two kinds, and one is the formula of partly standing up, and as hospital bed, its half lathe bed can arbitrarily rise and put, and the shortcoming of this kind of bed is to supply that half health (or above the waist or lower part of the body) is L-shaped changes posture activity, another kind is referred to as collapsible, it has bedstead and lathe bed, lathe bed comprises three parts, mid portion maintains static, two head part can be distinguished upwards folding and downwards folding, finally be deformed into chair shape for patient, the advantage of this kind of bed is that patient can change into normal person's sitting posture (shank is downward) by lying posture, realize whole body activity, and patient's defecation (setting up just hole separately at pars intermedia) that can be seated, feel pleasant, shortcoming is to need special bed special, take larger space, due to bed structure complexity, especially one end needs the deformation space of folding downwards, therefore bedstead and lathe bed must together be installed and used, and need to reserve separately and lay space, the above-mentioned formula of partly standing up nursing bed also exists needs whole bed to buy, the shortcoming that private space is placed.

Summary of the invention

The purpose of this utility model is to improve the weak point that prior art exists, provide a kind of simple in structure, easy to use, take up room mattress formula Multifunctional defecating bed chair little.

The technical solution of the utility model is: a kind of mattress formula Multifunctional defecating bed chair, feature is, having flat bed encloses, place and be provided with leading screw at bed, the two ends that enclose with bed respectively on two tops of leading screw are flexibly connected, screw thread on leading screw is the bidirectional helical that two ends subtend arranges, on leading screw, be provided with lead-screw driving device, this driving device can be manual (as crank), also it can be electronic (as driven with worm gear speed-reducing motor), place surface at bed and be provided with mobile bed plate, mobile bed plate comprises backboard, seat, lower limb plate and base plate, backboard, seat, between lower limb plate and base plate, be flexibly connected successively, on backboard, be provided with push rod, one end of push rod is flexibly connected with backboard, the other end of push rod is connected with screw, push rod is flexibly connected with leading screw one end by screw, below base plate, be also fixedly connected with screw, base plate is flexibly connected with the other end of leading screw by screw, on seat, be provided with just hole, bed below seat is placed and is provided with baffle plate, baffle plate is with just hole is corresponding, folding spacing angle between backboard and seat is not less than 90 degree.

Four ingredients of mobile bed plate are all movable, the backboard at two is connected with leading screw by structures such as screws respectively with base plate, owing to being set to bidirectional helical on leading screw, so in the time that leading screw rotates, always subtend of the movement locus that drives backboard and base plate, mutually close, otherwise mutually away from.When backboard and base plate mutually near time, can make the junction between these four mobile bed plates of backboard, seat, lower limb plate and base plate occur folding, because backboard is not directly connected with leading screw, base plate is directly connected with leading screw by screw, seat is not connected with leading screw with lower limb plate, therefore being equivalent to only have base plate is to be relatively fixed on leading screw, when motion, can not leave bed encloses, other three mobile bed plates enclose mutually all can erecting to leave bed when folding into a certain degree, and form the folded state of chair-like shape.Otherwise, when backboard and base plate mutually away from time, between four mobile bed plates, be opened, until " evening up " forms with bed and enclose the tabular bed board being abutted against.

In above-mentioned folded deformation process, making backboard, seat and lower limb plate erect to leave bed encloses and can realize in the following manner: the one, utilize the folding spacing angle (referring to inside knuckle between the two) between backboard and seat, folding spacing angle between backboard and seat reaches in limited time, can head on backboard and take advantage of a situation and erect by being connected to push rod on backboard, then drive seat and lower limb plate to erect; Another kind is that auxiliary firm pull bar can be set, one end of auxiliary firm pull bar is flexibly connected with backboard side, the other end of auxiliary firm pull bar encloses and is flexibly connected with bed, in the time that leading screw rotation starts deformable folding with mobile bed plate, auxiliary firm pull bar can instant pull-up backboard, then drive seat and lower limb plate to erect, assisted the distortion process of mobile bed plate.Certainly, can also realize by structures such as supporting cylinder, but because those structures are all too complicated, and cost is higher, does not meet the goal of the invention of the technical program, therefore repeats no more.

In order to realize better goal of the invention, on described leading screw, the two ends pitch of bidirectional helical can be inconsistent, is greater than the thread pitch corresponding to base plate below corresponding to the thread pitch of backboard below.

In order to realize better goal of the invention, enclose two bottom sides at bed and can also be provided with slideway, described push rod is flexibly connected with slideway.

This utility model advantage is compared with the prior art as follows:

1, this utility model does not have the supporting structures such as bedstead, before distortion, entirety is mattress formula shape, seat shape for placing at flat bed after distortion, therefore, this utility model is equivalent to directly to buy and to install with mattress form, especially it is very convenient to install, and can place on the ground, existing bed is upper, the first-class optional position of (rural area) a heatable brick bed, need not reserve separately installation site or buy supporting bed accessory, support etc. and take limited living space;

2, this utility model structural design is novel simple, utilize the bidirectional helical structure on leading screw to make mobile bed plate subtend be subjected to displacement distortion, not bi-directional drive still, and the strong point of supporting deformation is 2 common support (backboard and base plates), share the load-bearing of parts, not only Portable power saving, and greatly reduce the wear rate between each parts, patient's sensation also can be as snug as a bug in a rug;

3,, owing to adopting bidirectional helical structure, the screw that two subtends move has auto-lock function, though the mobile bed plate in distortion in which kind of state, patient's body weight is how, and screw slip phenomenon can not occur, safe.

Below in conjunction with drawings and Examples, this utility model is explained.
