Description
Technical field
The present invention relates to the field of medical instrument technology, more particularly, to a kind of accurate syringe of pen-holding type rack gear.
Background technique
Currently, the injection volume of some medical fluids has strict requirements, injection may excessively generate side effect, and injection is very few,
Expected effect may be not achieved.Existing syringe is made of needle tubing and piston rod, and the piston rod is embedded in the needle tubing,
And it is slid in the needle tubing.The piston rod is pushed, piston rod slides in the needle tubing, by the liquid medicine injection in the needle tubing
Enter patient's body.
It is injected using syringe to patient in medical staff, when having the medical fluid of strict demand to injection volume, medical staff exists
During pushing piston rod, conventional syringe is by the artificial dosage for pushing injector push-rod and naked eyes that judgement is gone to inject, no
It can complete to inject in the accurate dosage of 0.005~0.01ml level, injection volume is very likely more than defined dosage, or up to not
To defined dosage.Meanwhile in some injection process, the level reached to depth, that is, medical fluid that syringe needle is pierced into skin has very
High requirement needs more accurate and stablizes, such as the injection of creotoxin, sodium hyaluronate.Conventional syringe is unable to control less than 1mm
Accurate depth of needle control.Using the conventional syringe of dimension, especially when the medical fluid of absorption is more, syringe is whole
Body length is too long, and injector push-rod is far apart from syringe needle, and the grip and the control of accurate injection operation to medical worker cause pole
It is big inconvenient.
Current existing motoring syringe, generally pistol pattern, bulky (10~20cm), weight is big, mostly golden
Belonging to gun body, the grip position of hand farther out from syringe needle, and is in gripping with one hand posture, and hand motion is excessive when pulling injection spanner,
It cannot accomplish the precise and stable control of syringe.Meanwhile injection portion used in existing motoring syringe institute need to be using spy
The syringe or non-dismountable very customized, use cost is excessively high.
Therefore, the invention proposes a kind of accurate syringes of pen-holding type rack gear, change conventional injection mode, realize injection
The accuracy controlling of dosage and injection depth.
Summary of the invention
The present invention provides a kind of accurate syringe of pen-holding type rack gear, can not be accurate to solve injection dosage in the prior art
Control and syringe needle are pierced into the problem that the depth of skin can not fix, and improve injection precision, to reduce dose error bring danger
Evil.
Technical problem solved by the invention is realized using following technical scheme:
A kind of accurate syringe of pen-holding type rack gear, comprising: bracket and equipped with the position-limit mechanism in the bracket front end,
Syringe is fixed on the bracket, the tail portion of the syringe is connected with rack gear arrangement, and the rack gear arrangement passes through a processing
The dosage injected in the syringe is precisely pushed under the control action of terminal
The syringe includes syringe body, syringe needle, push rod, and the syringe body is fixed on described by fastener
On bracket, the fastener includes the first fastener and the second fastener, and first fastener and the second fastener are solid respectively
It is scheduled on the front and rear of the syringe body；
The rack gear arrangement includes power motor, power gear and rack gear, the push rod of the rack gear and the syringe
It is connected；
The position-limit mechanism is mainly too deep to prevent the syringe needle to be pierced into.
The position-limit mechanism is syringe needle positive stop hook as a preferred technical solution, and the syringe needle positive stop hook is two, described
Syringe needle is arranged between two syringe needle positive stop hooks.
The end of the syringe needle positive stop hook has arc fold bending portion as a preferred technical solution, to prevent stimulation skin.
The end of the syringe needle positive stop hook is fixed on the bracket by telescopic rod as a preferred technical solution, with
Realize the telescopic adjustment of syringe needle.
The position-limit mechanism is protective sleeve of syringe needle as a preferred technical solution, and the front of the protective sleeve of syringe needle has
The opening that syringe needle passes through can be accommodated, end has the helicitic texture with the support assorted.
The surface of the helicitic texture has instruction protrusion as a preferred technical solution, is revolved according to the helicitic texture
The angle turned can feed back the length that the syringe needle exposes.
First fastener and the second fastener are adjustable fastener as a preferred technical solution, are such as blocked
The fasteners such as hoop, anchor ear.
The push rod of the piston rod and the syringe is realized by third fastener and is fixed as a preferred technical solution,
Connection, the third fastener can be chosen for such as clip, anchor ear fastener.
The bracket is equipped with sliding rail as a preferred technical solution, has walking block on the rack gear, and the walking block is embedding
In in the sliding rail；The walking block is integrated with rack gear, has one when the walking block slides in the sliding rail
Fixed resistance will not occur sliding and be shaken with gravity, to prevent the error of injection precision.
There is on the syringe body metering scale as a preferred technical solution,.
The power gear is made of intermeshing gear wheel and pinion gear as a preferred technical solution, described small
Gear is connected with power motor, and the canine tooth wheel and rack is meshed connection, drives gear wheel rotation by pinion gear, to prevent
Only because power motor revolving speed is too fast, cause liquid outlet quantity not accurate.
The gear wheel and the diameter of pinion gear ratio are 2:1 as a preferred technical solution, and the diameter ratio of the two is bigger,
Precision is higher
In use, the position-limit mechanism on the end for passing through the adjusting syringe body, to prevent in use
The syringe needle be pierced into it is too deep, since the power teeth wheel and rack of rack gear arrangement is meshed connection, the processing terminal control power
The revolving speed and distance of motor push rack gear to move in sliding rail, and then push the push rod of the syringe in syringe body
It is mobile, to complete injection dosage accurate injection or absorption.
The invention has the advantages that: (1) work of pneumatic device by processing terminal is controlled, can be realized injection
Dosage is accurately injected or is drawn, and control is simple, easy to operate, is more suitable for medical and beauty treatment drug creotoxin, sodium hyaluronate
Injection can guarantee to inject in the accurate dosage of 0.005~0.01ml level, to reduce the harm of dose error bring.
(2) by the application of position-limit mechanism, can effectively prevent syringe needle to be pierced into too deep, meanwhile, can within 1mm water
Flat accurate depth of needle control.
(3) using the matching design of rack gear and sliding rail, so that the push rod of rack gear and syringe will not be slided with gravity
Dynamic and shaking, to prevent the error of injection precision.
