Description

A kind of clinical laboratory sampling bed

Technical field

The present invention relates to medical care equipment field, more particularly to a kind of clinical laboratory sampling bed.

Background technology

Sick bed can be divided into ABS sick beds, all steel sick bed, semi-stainless steel sick bed, all-steel plastic-spraying sick bed by material point Deng.Sick bed can be divided into medical hospital bed, family expenses sick bed by purposes point.Sick bed can be divided into electric hospital bed and manual disease by function point Bed, wherein electric hospital bed and can be divided into that five-function is electric hospital bed and three functional electric sick beds etc., manual sick bed can be divided into again pair to be shaken Sick bed, singly shake sick bed, flat board sick bed.

For to be treated in hospital department etc. or receive the patient for the treatment of, sick bed is their main activities field Institute, hospital management side and families of patients wish that patient can restfully couch and rest or receive treatment on one's sick bed, ensure patient Treatment phase and convalescence can normally be tided on one's sick bed, with wait terminate treatment date to facing.

However, if patient falls from sick bed accidentally, can not estimate to the injury that patient brings, because The state of an illness of some patients in itself is easy to because fall and bring secondary injury, such as some patients, itself be subject to be muscle or The damage of muscles and bones, if fallen under sick bed again, exacerbate the state of an illness of itself, it is also possible to which some patients are during treatment Fall under sick bed, also carry medical care device on body when falling, such as breathing mask etc., if fallen, be likely to Patient is caused to be in the boundary being in extreme danger because medical care device comes off.

Generally, patient is safely can to rest or receive on one's sick bed treatment, is on the one hand because uninterrupted Ground has medical personnel and carries out medical and nursing work, or has families of patients and look after for a long time, even in night, it is also possible to arranges special The nursing staff of door retains one's original salary patient is nursed, and shortens the unmanned nurse time of patient, on the other hand also in that some Patient still has certain ability to act, to oneself having carried out self specification, reduces the probability to fall from the bed.But medical care Personnel, families of patients or even the nursing staff that retains one's original salary are manually to nurse after all, and oneself also has the time had a meal, rested, can not be right Patient carries out the uninterrupted, nurse of 24 hours, and therefore, patient still has certain unmanned nurse time, meanwhile, also have Patient is to completely lose ability to act, for these patients, it is likely to once unintentionally turns over the hair for resulting in falling from bed event It is raw.

In order to avoid the generation of patient's falling from bed event, in the prior art, hospital management side also takes much positive arrange Apply, for example, transforming sick bed bed body, increase the height of guardrail, and set some geofences to set in sick bed bed body Standby and emergence call equipment, to reduce the possibility of patient's falling from bed, the trigger device of falling from bed alarm is provided for patient, these transformations Sick bed equipment afterwards reduces the generation of patient's falling from bed event to a certain extent.Meanwhile hospital management side also takes Measure, such as increase and the interaction and communication of families of patients, to reduce the time of the unmanned nurse of patient.

But to make mechanism excessively simple for these existing hospital bed structural reforms, because patient's falling from bed duration intervals are very of short duration, on The detection and warning device accuracy of detection stated be not high, detection efficiency is low, the increase of guardrail height and nurses the increase of time only The probability of patient's falling from bed can be reduced, without being avoided that the event of falling from bed occurs, most importantly, is lacked in the prior art to patient The fast reaction measure of falling from bed event and fast reaction equipment, fast reaction can not be carried out to patient's falling from bed event, can not be timely Patient body is quickly supported, leads to not the ill effect for avoiding patient's falling from bed.

Therefore, it is necessary to a kind of technical scheme of new sick bed fall arrest, the falling from bed of patient can accurately and efficiently be detected Event, can quickly it be alarmed, additionally it is possible to patient is given first aid to using some emergency reaction equipment, so as to effectively avoid disease People is improved the automation level of sick bed by injury is hit.

The content of the invention

In order to solve the above problems, the invention provides a kind of clinical laboratory sampling bed, by transforming existing hospital's disease Bed bed body, weight detection equipment, image detecting apparatus and ray detector pair are introduced in existing hospital bed bed body Patient's falling from bed event carries out accurate judgement, introduces some sources of early warning and is alarmed accordingly, it is often more important that, also introduce Targetedly urgent rescue equipment is effectively supported to the patient body to fall.

Compact Flash, for having prestored preset strength, presetted pixel point quantity, default rate of change and default picking-up height；

Wherein, module, which selects sub- equipment to carry out the filtration module of medium filtering based on maximum distribution radius selection, includes：Maximum point Cloth radius is bigger, and the filtration module of the progress medium filtering of selection is bigger, and maximum distribution radius is smaller, the carry out intermediate value filter of selection The filtration module of ripple is smaller；

Wherein, module selects filtration module selective in sub- equipment to include 3 × 3,5 × 5,7 × 7 and 9 × 9.
