Embodiment

The embodiment to the blood sampling sick bed of the present invention is described in detail below with reference to accompanying drawings.

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 Institute, hospital management side and families of patients wish that patient can restfully couch and rest or receive treatment on one's sick bed, it is ensured that patient Treatment phase and convalescence can normally be tided on one's sick bed, with wait terminate treatment date to facing.

If however, 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 falling and bringing 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, exacerbates the state of an illness of itself, it is also possible to which some patients are during treating Fall under sick bed, also carry medical care device on body when falling, such as breathing mask, if fallen, be likely to Because medical care device comes off and causes patient to be in the boundary being in extreme danger.

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 arrange special The nursing staff of door retains one's original salary patient is nursed, shorten the unmanned nurse time of patient, another aspect also in that some Patient still has certain ability to act, to oneself having carried out self specification, reduces the probability fallen from the bed.But, medical care Personnel, families of patients or even the nursing staff retained one's original salary are artificial nurse after all, oneself also have the time had a meal, rested, it is impossible to right Patient carries out the uninterrupted, nurse of 24 hours, therefore, and 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 stand up the hair for resulting in pendant bed event It is raw.

In order to avoid patient falls the generation of 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 that patient falls bed, the triggering device of pendant bed alarm is provided for patient, these transformations Sick bed equipment afterwards reduces the generation that patient falls 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, it is excessively simple that these existing hospital bed structural reforms make mechanism, because patient's pendant 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 that patient falls bed can be reduced, without being avoided that the event of pendant bed occurs, most importantly, is lacked in the prior art to patient Fall fast reaction measure and the fast reaction equipment of bed event, it is impossible to bed event is fallen to patient and carries out fast reaction, it is impossible in time Patient body is quickly supported, leads to not the ill effect for avoiding patient from falling bed.

In order to overcome above-mentioned deficiency, the present invention has built a kind of blood sampling sick bed, can accurately and efficiently detect patient's Bed event is fallen, can quickly be alarmed, additionally it is possible to patient is given first aid to using some emergency reaction equipment, so as to effectively keep away Exempt from patient by injury is hit, improve the automation level of sick bed.
