Abstract
The utility model discloses a flat-straight tracting device of a tracting bed for treating lumbar vertebra used in the field of medical care, which comprises a bed frame. A sliding bed cushion is arranged on the bed frame. One end of the bed frame is also provided with another bed cushion. Supporting arms are fixed to lower side faces of the sliding bed cushion. A supporting frame is fixed in the bed frame. A flat-straight actuating mechanism composed of a telescopic motor and a pulling pressure transducer arranged on any end of the telescopic motor is arranged between the supporting arms and the supporting frame. The utility model has the advantages of simple structure, convenient installation, precise traction force control, low cost, low malfunction rate, and low rework rate and reduces operation noise.
Description
This utility model relates to the straight traction apparatus in the lumbar treatment extension table that uses in the medical field.
At medical instruments field, the lumbar treatment extension table is widely used in the lumbar disc disease of treatment human body, and the lumbar vertebra of human body is carried out straight stretching and drawing to reach therapeutic purposes.At present, the straight traction apparatus of disposing in the lumbar treatment extension table comprises bedstead, and bedstead is provided with the slip mattress, and the slip mattress can slide on bedstead, also is provided with auxiliary mattress at an end of bedstead; Downside at the slip mattress is fixed with support arm, is fixed with support in bedstead, and the straight actuating mechanism of installing between support arm and support is an oil cylinder, by the action back and forth of oil cylinder push rod, drives the slip mattress through support arm and do straight moving on bedstead; For guaranteeing the operate as normal of oil cylinder, also must dispose parts such as motor, gear pump, integrated oil path block, electromagnetic valve, hydraulic control one-way valve, choke valve, overflow valve simultaneously; Be the size of control pull strength, pull pressure sensor also be installed at an end or the other end of oil cylinder; Because this mechanism components is more, install cumbersomely, to waste time and energy, cost is higher; And oil circuit leaks easily, pollutes, and fault rate is higher; The control accuracy of pull strength is also lower, and the error about 2 kilograms is arranged usually.
The purpose of this utility model is to provide a kind of simple in structure, easy for installation, pull strength to control the straight traction apparatus in the more accurate lumbar treatment extension table.
For achieving the above object, the technical solution adopted in the utility model is: the straight traction apparatus in the described lumbar treatment extension table, comprise bedstead, and bedstead is provided with the slip mattress, the slip mattress can slide on bedstead, also is provided with another mattress at an end of bedstead; Downside at the slip mattress is fixed with support arm, is fixed with support in bedstead, and straight actuating mechanism is installed between support arm and support, and described straight actuating mechanism is flexible motor, at an end or the other end of flexible motor pull pressure sensor is installed.
The utility model has the advantages that: one, simple in structure, easy for installation, improved work efficiency greatly, reduced cost; Two, pull strength is controlled easily, and degree of accuracy is higher, generally has only 0.2 kilogram error; Three, owing to do not re-use parts such as gear pump, greatly reduce running noises, alleviated sound pollution and possible oily leakage pollution; Four, prolonged the service life of complete machine, fault rate, repair rate are low.
Below in conjunction with the drawings and specific embodiments this utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
As shown in Figure 1, the straight traction apparatus in the lumbar treatment extension table described in the utility model comprises bedstead 7, and bedstead 7 is provided with slip mattress 2, and slip mattress 2 can slide on bedstead 7, also is provided with mattress 1 at an end of bedstead 7; Downside at slip mattress 2 is fixed with support arm 6, in bedstead 7, be fixed with support 3, between support arm 6 and support 3, straight actuating mechanism is installed, this straight actuating mechanism is flexible motor 4, an end 10 or the other end 9 at flexible motor 4 are equipped with pull pressure sensor 5, and promptly pull pressure sensor 5 can be installed in the right-hand member 10 of flexible motor 4 or the position of left end 9 arbitrarily.
During work, the lumbar vertebra of human body is distinguished tighten with bandage on mattress 1 and slip mattress 2 with the upper and lower part of patient's waist between slip mattress 2 and mattress 1, is set the size of pulling force by control chamber 8 according to the state of an illness; Described straight traction apparatus has two kinds of basic acts processes, the one: control chamber 8 sends instruction and makes flexible motor 4 actions, promoting slip mattress 2 by support arm 6 moves to the right, promptly increased the distance between slip mattress 2 and the mattress 1, the pressure that this moment, pull pressure sensor 5 was subjected to increases, when its pressure increased to setting value, control chamber 8 sends instruction immediately made flexible motor 4 stop action; The 2nd: if control chamber 8 has been set off time, control chamber 8 sends instruction when arriving setting value, make flexible motor 4 actions to remove the pressure that pull pressure sensor 5 is subjected to, flexible motor 4 drives slip mattress 2 by support arm 6 and draws close to mattress 1, the pressure that this moment, pull pressure sensor 5 was subjected to is decreased to minimum thereupon, and control chamber 8 sends instruction makes flexible motor 4 stop action; So perseveration reaches therapeutic effect.
