Description
Technical field
The present invention relates to medical assistant product field, more particularly to a kind of hydraulic pressure spring-grip, it is mainly used in auxiliary blood drawing.
Background technology
In order to accelerate the blood flow during blood drawing when donating blood, prevent vasopasm, staff would generally provide one and hold
Power ball is to blood donor.Existing pressure relief ball is mainly with circular or egg type ball made of the highly elastic materials such as PU.Blood donor grabs
After holding pressure relief ball, because its elastomer material acts on, pressure relief ball will quick rebound, and blood donor can feel that pressure relief ball brings finger
Pressure.It is general lasting to grasp for several times, with regard to the numb heating in the centre of the palm can be felt, this be due to palm in lasting grasping pressure relief ball,
Pressure relief ball can effectively stimulate major acupuncture point of palm, so as to stimulate circulation, reach and accelerate blood flow and prevention blood vessel
The effect of spasm.However, there is following defect in traditional pressure relief ball in use：(1), blood donor is difficult to control grip
Degree；(2), blood donor does not know the optimum frequency for grasping pressure relief ball.
The content of the invention
The task of the present invention is to provide a kind of liquid that user can be prompted to control palm grip dynamics and frequency in blood drawing
Spring-grip is pressed to solve the deficiencies in the prior art.
The present invention is achieved through the following technical solutions goal of the invention：

Part and the hydraulic pressure force application mechanism for opening or closing the signal control assembly, the signal control assembly control prompting
The switch of signal.
In some embodiments of the invention, the force application structure includes hydraulic bjuffer and stress support, stress branch
The four edges of frame are connected with each other by jointed shaft, and catercorner first jointed shaft and the 3rd jointed shaft are separately fixed at the bullet
The both ends of property cavity, the second relative jointed shaft and the 4th jointed shaft are connected to the both ends of the hydraulic bjuffer, and first
Jointed shaft and the 3rd jointed shaft drive the second jointed shaft and/or the 4th jointed shaft to be set respectively towards corresponding after by the extruding of flexible cavity
The lateral movement of flexible cavity two of the signal control assembly is put, when flexible cavity is squeezed, liquid is fixed on stress support
The jointed shaft at compression buffer both ends is moved towards signal control assembly, and when stress reaches preset value, signal control assembly is cut with scissors
The impact force of spindle connects circuit and sends cue.
Further, in addition to support block, support block are fixed in flexible cavity close to one end of the flexible cavity, phase
To the other end be fixedly connected by inline mode with first jointed shaft or the 3rd jointed shaft, set support block make to be applied to
Power on stress support is evenly.
Further, the hydraulic bjuffer includes working chamber and buffer bar, and back-moving spring is arranged with outside working chamber, by
This, back-moving spring can help buffer bar to reset, and the time required for resetting can be by selecting different spring constants to be adjusted
It is whole so as to prompt bleeder grasp spring-grip frequency.
Further, one end of the back-moving spring is fixedly connected with the bottom of working chamber, the end of the other end and buffer bar
Portion is fixedly connected, and thus, spring can hinder the second jointed shaft and the 4th be hinged axial both sides motion after pulling open, only work as bleeder
Holding dynamics when being more than setting value, could collision alarm control assembly open cue.
Further, the signal control assembly includes circuit board, and light emitting diode, metal on circuit board
Piece and the little spring for being used as shock sensor, little spring and sheet metal selective exposure, when the vibrations of little spring stress and sheet metal
When being in contact, circuit turn-on, lumination of light emitting diode provides cue.
Further, the signal control assembly is arranged in a small cavity of elasticity, the center of the small cavity of elasticity and
Second jointed shaft and/or the 4th jointed shaft are relative, and thus, whole signal control assembly is in the small cavity of elasticity, not only
With protection circuit plate and component therein the making of spring-grip can also be made more convenient.
In some embodiments of the invention, the support block is bonded in institute close to one end of flexible cavity by seccotine
State in flexible cavity, the small cavity of elasticity is bonded in backwards to the side of the second jointed shaft or the 4th jointed shaft by seccotine
In the flexible cavity.
Further, the flexible cavity material is silica gel or rubber, and the outer shape of flexible cavity is toy capitiform,
The capitiform of the pretty animals such as blue or green baby, dog or cat is arranged to, can be shifted tight when the notice of bleeder especially child draws blood
Opening mood prevents vasopasm.
Further, outside of the flexible cavity at support block is provided with finger pressure area, and finger pressure area corresponds to the petty action
Two eyes of thing or the intermediate region of ear, finger pressure area is set bleeder is correctly grasped spring-grip.
Hydraulic pressure spring-grip provided by the invention has advantages below：
1st, cue is used as using vibrations the luminous of light emitting diode, whether suitable the dynamics that bleeder is grasped is visual
Change, bleeder is adjusted dynamics size in good time, improve hospital's blood drawing efficiency.
2nd, after flexible cavity is grasped extruding until restoring to the original state, bleeder can grasp again, be driven using back-moving spring
The interval that the buffer bar of hydraulic bjuffer is slowly retracted grasps the frequency of spring-grip as bleeder, bleeder is accurately sent out
Power.
3rd, the shape of flexible cavity using the head dummy that can be had a tenderness for small animals and is grasped when dynamics reaches setting value and can lighted, and is increased
The interest of spring-grip, nervous psychology when transferable bleeder especially child draws blood prevent vasopasm, carried
The high operating efficiency of medical personnel.
