Description
Technical field
The invention belongs to medical auxiliary apparatus technical field, more particularly to a kind of back belt type multifunctional transfusion rack.
Background technology
During clinical transfusion, due to existing infusion support is typically secured on bed, on transfusion chair or suspension is in orbit, infusion
When patient activity can be significantly restrained, many patient's out-of-bed activities and rehabilitation can be impacted.Infant or child infusion
When, due to the hyperactivity of child, often occur being difficult to sit silent or recumbency has carried out infusion.Then occur defeated
During liquid, when child cries and screams, two parents assist, and a people lifts one people of infusion support and has child in arms to slip in lesion or corridor
Reach；There is arm and aches quickly in the parent for lifting infusion support, it is impossible to it is permanent to adhere to, the parent to hold a baby in one's arms can also move it is very tired and by
Easily leading to child's activity in infusion length of tube institute limited capacity causes transfusion needle to come off equivalent risk, or highly indefinite, causes infusion pressure
Change and cause transfusion speed indefinite.
With the raising of social modernization's level, the requirement that people live for entertainment is also higher and higher, with it is three-dimensional,
The output true to nature of feeling of immersion is also gradually applied to these fields for the virtual reality technology of mark.By to the objective reality world
Simulation create a virtual world, and children are based on their experience of lifes and habit accumulated in real world
The behavior pattern of inertia is interacted with virtual world.So feeling of immersion is stronger, i.e., the row that children occur in virtual world
For or the experience and perception closer to them in real world of the image watched, more can obtain popular favor.And 3 is aobvious
The stereo perception that the technology of showing is brought is even more to have arrived the presentation of virtual world is spatially extended outside screen.
In most of stereoscopic display devices at present on the market, when multiple children watch same screen display, he
The picture seen be often consistent.I.e. when having object of which movement on the picture of display, the fortune for the object that they are seen
Dynamic direction is also consistent.But in real world, when there is object " winged " next towards us, the people of different visual angles position sees
The movement locus of object be different in fact.This illustrates limitation of the current 3D display equipment in terms of children's feeling of immersion is improved
Property.Therefore, the present invention devises a kind of filter antagonism project dummy emulation system for drawing display more based on solid, and specifically
Understand that the virtual tennis carried out based on the system resists event, the 3D game pictures of different visual angles can be respectively outputted to
In the eye of respective player, and during player can be played as carrying out tennis tournament in real world by corresponding action control
Correspondence role run, swing the bat so that game have more preferable interactivity and feeling of immersion.
And the prior art does not utilize this point, applied in the infusion process of children, make the infusion feared state of mind of children into
Row transfer；It is easy to work so as to reach nurse.
In conclusion problem existing in the prior art is：Existing infusion support cannot be carried with, and usually limit patient
Receive infusion treatment in bed or on seat；Activity under the bed of existing infusion device limitation patient, is unfavorable for rehabilitation, especially
It is the patient that early ambulation is needed after performing the operation；Scope of activities is limited when patient fluid infusion treats；Even infusion support bottom
Belt wheel be can move patient can out-of-bed activity, but take action still need on the other hand push or other people push infusion support movement；
Existing infusion support flexibility ratio is poor, and when infant transfusion easily makes a noise, and parent, which is frequently necessary to have child in arms, to walk about, and allows child's peace and quiet to control
Treat, existing infusion device can only two adults cooperate (1 people holds a baby in one's arms, 1 people lifts transfusion pole)；Present infusion device is considered not
Enough hommizations.
