Description
Technical field
The utility model relates to a kind of medical auxiliary bed, in particular to a kind of medical auxiliary bed that can vertically turn on one's side.
Background technique
During many ultrasonic examinations, physician guidance patient carries out specified posture transformation, some of them larger amplitude
The transformation of degree includes left and right vertical sides are turned over, 45 degree of left and right is turned on one's side etc..For those can not paleocinetic group, they often need
Above-mentioned movement is completed by medical care family members et al. auxiliary, in busy ultrasound room, above situation will affect ultrasonic examination
Efficiency, it is quickly tired to will also result in medical staff.In most circumstances, left-right rollover necessarily results in that patient is separate or mistake
Spend close to inspecting doctor, inspecting doctor in order to as far as possible accurately to patient checked often sideway bend over to touch from
Place except own normal motional course will lead to inspecting doctor's backbone substantially lateral bending in the past for a long time;When patient is in inspecting doctor
That leans on is excessively close, inspecting doctor's shoulder can not conscious towering-up to adapt to narrow space, for a long time in the past can with the diseases such as scapulohumeral periarthritis,
Above situation will endanger the health of inspecting doctor.
During Rehabilitation, patient's maximum probability of long-term bed can with diseases such as pressure sores, the generation of pressure sore with
The factors such as pressure, humidity, nutrition, age are related, and wherein pressure at right angle is the most important reason that pressure sore is formed, frequent rollover
Such situation can effectively be avoided;Medical staff needs to make patient completely vertical when paralysed patient on to bed carries out daily nursing
Rollover to be wiped, the work such as dressing, human assistance rollover is time-consuming and laborious.
The existing hospital bed rollover amplitude with rollover function is smaller, and generally less than 30 °, hospital bed realizes the mode of rollover function
It is to force patient to turn on one's side to squeeze patient side body by combining the fold of bed board mostly, that patient experiences in bed is poor,
Comfort level is low, and turn amplitude is too small, cannot play the role of having ignored the actual application effect of rollover with practical significance;Bed
The amplitude that plate is integrally overturn is small, and main cause is because the realization of its rollover function is to drive bed board by push rod or hydraulic cylinder
, push rod stroke is limited and easily collides with rod piece around, limits its movement travel, has bed board entirety turn over function
Product mostly without side shield, so only 20 ° or so of practical rollover, patient safety sense is low on bed.
Summary of the invention
