Description
Technical field
The present invention relates to the field of medical instrument technology, more particularly to a kind of medical bed easy to fluid infusion.
Background technology
Patient's bed used when accomplishing may be collectively referred to as medical bed, and medical bed is referred to as sick bed, care bed etc., is
What patient used in mastery, there are various big hospital, health clinics in towns and townships, sanatorium, community medical service center in main field of employment
Deng.Patient, which can be lain in medical bed, to rest, recuperates, fluid infusion, having a meal, and many patients need hanging point for a long time
Drop, needs when usual fluid infusion to lie on a bed, however many patients all run into that Nature calls when fluid infusion it is tired
Disturb, this usually require family members dropping bottle is removed, elevate after and patient's synchronizing moving, toilet in ability, patient oneself be difficult
Lift toilet on dropping bottle, especially family members not when, it is very inconvenient that patient is turned on toilet on drop.
The content of the invention
The present invention is in order to solve the above problem of the prior art, there is provided a kind of medical bed easy to have an intravenous drip, patient
Oneself can go to go to toilet with drop medical bed away from keyboard during having an intravenous drip, more convenient to use.
To achieve these goals, the present invention adopts the following technical scheme that：
A kind of medical bed easy to fluid infusion, including bedstead, the support feet for being located at both ends on the downside of bedstead, the both ends of the bedstead are set
There is upright bar, slide is equipped between the upper end of two upright bars, the slide is equipped with sliding seat, and the lower end of the sliding seat is equipped with
Hanging ring, hook base is connected with the hanging ring, and the upper end of the hook base is connected by linking up with hanging ring, the hook base
Both sides are equipped with drop suspension holdfast, and the lower end of the hook base is fixed with self-positioning telescopic rod, and the lower end of the telescopic rod is set
There is a base, the outside of the base is rotatablely connected between the inner of the supporting rod and base circumferentially arranged with three supporting rods,
Support foot pad is equipped with the outside of the outer end of the supporting rod, the outer end of the self-positioning telescopic rod is arranged with stop collar, the limit
It is slidably connected between position set and self-positioning telescopic rod, the outside of the stop collar is equipped with locking handwheel.Hook base by hook with
Sliding seat connects, and sliding seat can be moved along slide, and when patient lies in fluid infusion in medical bed, dropping bottle is suspended on drop suspension
Stent；When needs go to toilet, is outgoing when patient hangs drop, self-positioning telescopic rod is pulled downward on, then by three branch
Strut is deployed into horizontality, opens the bottom that stop collar is slided into self-positioning telescopic rod by locking handwheel, under stop collar
End face is spacing to the inner compression of support feet, so that three support feets keep horizontal open configurations, then will link up with hanging
Ring departs from, and hand holds self-positioning telescopic rod with regard to that can leave medical bed, while can also stand self-positioning telescopic rod on the ground, can be with
Both hands are liberated, is not interfered with when having an intravenous drip and has a meal, goes to toilet, use very maneuverability；, will after returning in medical bed
Supporting rod folds, and self-positioning telescopic rod is shortened, and is then connected hook with hanging ring.
Preferably, the lower face of the stop collar is equipped with annular positioning groove, the outside end of the supporting rod is fixed with
Positioning pin.After the outer end of supporting rod is folded up, positioning pin straight up, then moves down stop collar a bit so that positioning pin
Into in annular positioning groove, locking handwheel is then tightened, realizes the folding positioning of support feet.
Preferably, the bedstead is equipped with fixed bed plate and dynamic bed board, the inner of the dynamic bed board is hinged with bedstead, institute
State fixed bed plate, the top surface of dynamic bed board is equipped with mattress, be equipped with side plate on the downside of the both sides of the bedstead, be equipped between two blocks of side plates
Screw rod, the screw rod are rotatablely connected with side plate, and two sections of oppositely oriented screw threads, every section of screw thread are arranged with the screw rod
On be equipped with a swivel nut, the side of the swivel nut is equipped with rotation seat, and the bottom middle part of the dynamic bed board is equipped with two balls
Cut with scissors, connected one to one between the rotation seat and two flexural pivots on two swivel nuts by two mandrils, outside one end of the screw rod
Side is equipped with the unidirectional driving device for being used for driving screw rod positive and negative rotation, and the outside of the unidirectional driving device is equipped with handle.Patient lies in
In medical bed, it is desirable to when tilting recumbency above the waist, need to adjust dynamic bedplate angle at this time, patient oneself adjusts unidirectional driving
Device, a hand gripping handle, front-rear reciprocation movement, so that screw rod rotates forward, two swivel nuts are close to each other, two mandrils
Dynamic bed board is jacked up, since the inner for moving bed board is hinged with bedstead, dynamic bed board can rotate, and dynamic bed board turns to properly
Release handle behind position, swivel nut can be with the screw thread self-locking on screw rod and so that dynamic bed board keep subtended angle to stablize；Need to be laid flat dynamic bed
During plate, unidirectional driving device is adjusted, when driving handle moves back and forth, screw rod rotates backward, so as to bed board will adjust altogether to horizontal
State；This kind of medical bed, the angle of the separately adjustable dynamic bed board of patient's energy to lie on a bed, adjusting is very convenient, without bothering others
Help, overall stability are good.
Preferably, the outer end of two sections of screw threads is equipped with position limiting convex ring on screw rod, between position limiting convex ring and the end of screw rod
For polished rod portion, the polished rod portion of screw rod is equipped with sliding sleeve, pull rod is equipped between the side of the sliding sleeve and bedstead.Undertaken by pull rod
Screw rod is supported the active force of bar, prevents screw rod overstress and deforms, and improves overall stability.
Preferably, unidirectional driving device include housing, end cap, the lower end of the handle with being fixedly connected on the outside of housing,
The outside of the housing is equipped with baffle ring, is equipped with inner bearing in the baffle ring, and outer retainer is equipped with outer bearing, the side plate outside
Side is equipped with shrinkage pool, and the outer bearing is caught in shrinkage pool；The center of housing is equipped with through hole, and one end of the screw rod, which passes through, to be led to
Hole is stretched into housing, interior positive ratchet, the anti-ratchet being equipped with screw rod fixation of the housing, the ratchet on positive ratchet, anti-ratchet
Direction is opposite；The inner wall of the housing is equipped with connecting seat, and the connecting seat is equipped with rotational pin, and the both ends of rotational pin are set respectively
There are positive pawl, anti-pawl, the positive pawl coordinates with positive ratchet, and the anti-pawl coordinates with anti-ratchet, positive pawl, anti-spine
