Abstract
The invention discloses a kind of novel pressure to control syringe, including syringe（1）, syringe（1）Include piston（2）, piston（2）Upper connection piston shaft（3）, piston shaft（3）Upper setting piston handle（4）, in syringe（1）Bottom sets nipple（5）, nipple（5）On cover needle point（6）, in piston shaft（3）Interior setting press rods（7）, in piston handle（4）Upper setting pressure contact（8）.The beneficial effects of the invention are as follows：The present invention is reasonable in design, simple in construction.Novel pressure control syringe at work, is up to Expected Results, and piston will preferably be bonded syringe during injection, and make its propulsion more smooth, will be very efficient and convenient during injection.
Description
Technical field
The present invention relates to medical field, and syringe is controlled more particularly, to a kind of novel pressure.
Background technology
Syringe is a kind of common medical instruments, and early in the 15th century, Italian's Ka Di Nellies just propose syringe
Principle.The scientific instrument that syringe can be used in Medical Devices, container, such as some chromatographies are injected through diaphragm of rubber.
Air embolism will be caused by directing injection of the gas into blood vessel.It is to inject that air is removed from syringe to avoid the method for embolism
Device is inverted, gently beats and then a little liquid is extruded before blood flow is expelled to.
In some precision rather than the occasion of germ overriding concern problem, in quantitative chemical analysis, due to Glass syringe
The error of device is smaller, push rod gliding smoothing is so still using.
Can also when cooking carnivorous with syringe toward injecting some juice to improve taste and quality in meat, or
It is injected into when bakeing in cake.Ink can also be filled into print cartridge by syringe.May also occur injection when medical to push away
Enter slowly, resistance is big, and piston seal degree not enough causes a series of problems etc..
The content of the invention
The present invention provides a kind of novel pressure control syringe, including syringe, syringe for this to solve present problems
Piston is included, piston shaft is connected on piston, piston handle is set on piston shaft, nipple is set in syringe bottom, covers pin on nipple
Point, press rods are set in piston shaft, pressure contact is set on piston handle.Preferably, the piston is to onlap condensation material,
With the high stickiness of high sealing.
The beneficial effects of the invention are as follows：
The present invention is reasonable in design, simple in construction.Novel pressure control syringe at work, is up to Expected Results, injected
When piston will preferably be bonded syringe, and make its propulsion more smooth, will be very efficient and convenient during injection, press rods and pressure are touched
The setting of point will be used cooperatively, and when press rods reach certain pressure, pressure contact stretches out therewith, will be safer when promoting
Smoothly, user is reminded accurately to control propulsion dynamics.
Brief description of the drawings
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein：
Fig. 1 is the front view of the present invention.
Embodiment
All features disclosed in this specification, or disclosed all methods or during the step of, except mutually exclusive
Feature and/or step beyond, can combine in any way.
Any feature disclosed in this specification, unless specifically stated otherwise, can be equivalent by other or with similar purpose
Alternative features are replaced.I.e., unless specifically stated otherwise, each feature is an example in a series of equivalent or similar characteristics
.
As shown in Fig. 1 a kind of novel pressure control syringe, including syringe, syringe include piston, connected on piston
Piston shaft, piston handle is set on piston shaft, nipple is set in syringe bottom, covers needle point on nipple, pressure is set in piston shaft
Power bar, sets pressure contact on piston handle.Preferably, the piston has the high stickiness of high sealing to onlap condensation material.
The beneficial effects of the invention are as follows：
The present invention is reasonable in design, simple in construction.Novel pressure control syringe at work, is up to Expected Results, injected
When piston will preferably be bonded syringe, and make its propulsion more smooth, will be very efficient and convenient during injection, press rods and pressure are touched
The setting of point will be used cooperatively, and when press rods reach certain pressure, pressure contact stretches out therewith, will be safer when promoting
Smoothly, user is reminded accurately to control propulsion dynamics.
The invention is not limited in foregoing embodiment.The present invention, which expands to, any in this manual to be disclosed
New feature or any new combination, and disclose any new method or process the step of or any new combination.
