Description

Medical treatment detection device

Technical field

The present invention relates to the field of structural design of Medical Devices, and in particular to a kind of medical treatment detection device.

Background technique

When in use, the needs based on operation, Clinics and Practices generally require operating platform or control panel to Medical Devices Height (control panel of such as ultrasonic device) can be adjusted in a certain range, i.e. realization elevating function.When realizing lifting, need Easy to operate, operating force is light, and can stablize the height for resting on needs, and here it is the basic need proposed to elevating function It asks.

The control panel of desk-top ultrasonic device currently on the market can be gone up and down in a certain range mostly, implementation master There are vertical lift and two kinds of inclined lift, it is especially most commonly seen to be vertically moved up or down.Regardless of being that vertical lift or inclination rise Drop, what jacking system mostly used greatly the gas spring with self-locking to realize, i.e., gas spring is pulled near the handle of control panel Control zipper, come control gas spring valve folding so that drive control panel lifting and locking, when pull zipper, gas bullet Spring valve is opened, and control panel can easily go up and down, and when unclamping zipper, gas spring valve-closing simultaneously locks motionless, at this moment can be held By biggish load, the initial force value of general gas spring and the gravity of support member are close, and such staff's operating force will not It is too big.

Due to above-mentioned up-down mode mainly or based on manual operation, although elevating mechanism can balance most hold Weight, but manpower auxiliary is still needed to lift and push when lifting, especially when leakage or equilibrant force design deviation occur for gas spring When larger.So allowing doctor more energy can be concentrated on diagnosis and treatment and and patient to realize that descending operation is more easily easy Communication on, and also to bring the high-grade sense of better operating experience and equipment, also there is a small number of desk-top ultrasonic devices at present Jacking system realize Electronic control lifting, i.e., need to only press ascending, descending button can realize the lifting of control panel, unclamp Button, control panel are locked at the height of needs.The implementation of electric up-down can also be divided into from hand-operated lifting derivation Two kinds of electric up-down of vertical electric lifting and inclination.Wherein vertical electric lifting adds guiding to slide generally by Linear motor-driven push rod Rail realizes, i.e., drives control panel to go up and down along directive slide track by the flexible of motor control screw rod in Linear motor-driven push rod And locking；The inclination electric up-down occurred at present is then by groups such as motor, gear drive, inclined lift arm, gas springs At a set of more complicated mechanism realize, drive inclined lift arm angle to put by the rotation of motor control gear pair It moves to realize lifting, gas spring plays equilibrant force, since gear pair does not have self-locking function, in order to support the jacking system Control panel can stablize rest on need height, then a clutch mechanism is increased between motor and gear pair, go up and down When clutch is unlocked, by clutch locks when lifting stops.

For the elevating mechanism realized by the gas spring with self-locking, although gas spring can balance whithin a period of time The overwhelming majority, which is held, cuts weight, but all there is gas leakage and the risks of force degradation for most of gas springs, after a period of use The human assistance operating force needed will increase, and it is difficult and laborious to will cause lifting；Sometimes even will appear because of gas spring force value Decay it is excessive cause self-lock force also obviously to weaken, lead to situation that cannot be self-locking, thus need replacing gas spring, greatly increase Maintenance and after service cost.

The vertical electric for adding directive slide track to realize by Linear motor-driven push rod is gone up and down, bending resistance square ability is limited (to exist The lower pressure born on control panel handle is limited), the noise of the generation of line handspike is larger when lifting, lifting speed also compared with Slowly, and the Linear motor-driven push rod mechanism that adds directive slide track to form need to extend vertically through most of region of desk-top ultrasonic device, meeting Hosting space is occupied, while increases maintenance difficulties；Furthermore when non-transformer or machine are in off-mode, which is difficult to reality Now manually adjust the function of control panel height.

It is electronic for the inclination realized by a set of mechanism such as motor, gear drive, inclined lift arm aerating spring Lifting, since this set mechanism structure is complicated, cost is also corresponding higher, while maintenance difficulties are also larger.When non-transformer or machine close When machine state need to manually adjust control panel height, unclamped though clutch can be triggered by external driving lever, which can make Elevating mechanism held by it gravity cut it is instantaneous suddenly under fall on extreme lower position, since falling speed is larger, there are certain peaces Full blast danger, also makes the operating experience of operator not good enough.

Based on this problems of the prior art, need to be further improved.
