Description
Technical field
It is a kind of needleless injector with electric functions the present invention relates to medicine and technical field of medical instruments.
Background technology
Needleless injector is a kind of by the pressurization of external power supply liquid medicine, and makes liquid drug with high-voltage high-speed
Form by very thin micropore, penetrate skin, enter into a kind of internal equipment.Liquid drug can not be direct by syringe needle
Human or animal's skin is penetrated to enter into vivo.
It is small injection volume the characteristics of generate many biological agent similar drugs, these medicines with the development of pharmaceuticals industry,
Often injection.The syringe for having pin can bring the fear and the pain of acupuncture to pin to user.Needleless injector can be effective
Avoid these problems.Simultaneously needleless injector can also make injection medicine more they tend to dispersion, be conducive to medicine absorption and
Reduce the infringement to hypodermis, it is to avoid form scleroma.
Existing needleless injector mainly has many weak points.
1st, the basic armrest of civilian needleless injector is moved and gives needleless injector pressurization, and user uses inconvenience.
2nd, the length of existing electric needleless injectors is long, uses inconvenience.
With the development needleless injector of technology should be able to reach it is electronic get it filled, electric injection, display screen dose indicating with
And communicated with the external world, injection dosage and injection time collect statistics and to be sent to the function of formulating position.
The content of the invention
It is an object of the invention to provide a kind of needleless injector with electric functions, it can be by built-in motor
The power resources that electronic mode is got it filled and injected to needleless injector, reliable operation, easy to use, small volume.
To achieve the above object, the present invention takes following technical scheme：
A kind of needleless injector with electric functions, it includes piston (1), pencil wall (2), shell (3), motor
(5), screw mandrel (8), compression body (9), steel ball (10), button (11), button spring (12), lock (13), push rod (14), pressure bullet
Spring (15), it is characterised in that：The compression body is tubular structure, and a screw has been extended perpendicularly out in the lateral wall of compression body (9)
(16) screw mandrel (8), is socketed with the screw, one end of the screw mandrel is connected with motor shaft (6)；The other end and shell of the screw mandrel
(3) one end connection；The axis of push rod (14) and the diameter parallel of motor shaft (6).
The rotating shaft (4) of the screw mandrel other end carries out rotation and is connected with shell (3) by bearing (7).
This needleless injector built-in motor, motor is connected with screw mandrel.Motor is rotated will drive screw mandrel to rotate, screw mandrel
Rotation can drive the internal thread screw that has being enclosed within screw mandrel to move.The movement of compression body will compression spring.When spring-compressed is arrived
During certain position, the push rod of spring inner can be locked by the steel ball in compression body.By after locked, motor is reversely rotated just push rod
Push rod and piston can be driven to reverse movement, the purpose for drawing medicine and adjustment injection dosage is reached.
The position that dosage difference compression body according to setting is moved is different.After compression body stops, button is pressed just with hand
Can carry out injecting.
The axis of push rod of the invention is parallel with the axis of motor, and being compared with coaxial structure can shorten needleless
The length of syringe.Its internal motor for setting, with the startup of precise control motor and stopping and can rotate and reverse.
The beneficial effects of the invention are as follows：It can be got it filled and noted by the electronic mode of built-in motor to needleless injector
The power resources penetrated, reliable operation, easy to use, small volume.

Specific embodiment
Referring to shown in accompanying drawing：A kind of needleless injector with electric functions, it includes piston 1, pencil wall 2, shell
3rd, motor 5, screw mandrel 8, compression body 9, steel ball 10, button 11, button spring 12, lock 13, push rod 14, compression spring 15, the pressure
Contracting body is tubular structure, and a screw 16 has been extended perpendicularly out in the lateral wall of compression body 9, and screw mandrel 8 is socketed with the screw, should
One end of screw mandrel is connected with motor shaft 6；The other end of the screw mandrel is connected with one end of shell 3；The axis of push rod 14 and motor shaft 6
Diameter parallel.
The rotating shaft 4 of the screw mandrel other end carries out rotation and is connected with shell 3 by bearing 7.
Accompanying drawing 1 is stress-released condition, and piston 1 is located at and medicine is sealed when playing a part of to get it filled and inject in pencil wall 2.
What is be connected with piston 1 is push rod 14, and the outside of push rod 14 is cased with compression spring 15, and the rear end side wall of push rod 14 is provided with groove 17, steel
Pearl 10 can be embedded in the groove 17.The front end of compression spring 15 contacts with the push rod boss 18 of push rod 14, compression spring 15
Rear end contacts with platform in compression body 9.Compression body 9 can move axially and compress and move compression spring 15.The connection of compression body 9
Screw 16 has internal thread, and internal thread is screwed with screw mandrel 8.The rotation of screw mandrel 8 can drive screw 16 to move axially.Screw mandrel 8 and motor 5
Connection, when motor 5 is rotated, screw mandrel 8 can be rotated together.
Accompanying drawing 2 is pressurized state.When syringe needs work, touch switch button 19, motor 5 can rotate, and drive silk
Bar 8 is rotated, and the rotation of screw mandrel 8 can drive compression body 9 to be moved to the left by screw thread.The right-hand member of push rod 14 is promoted near lock 13
The compression button spring 12 of lock 13, when in the groove 17 for moving to certain position steel ball 10 and can entering into the right-hand member of push rod 14, presses
Button 11 is outwards ejected in the presence of button spring 12.Steel ball 10 has been pressed in the recessed of the right-hand member of push rod 14 by the platform of the end of button 11
In groove.So as to push rod 14 is locked together with compression body 9.
Accompanying drawing 3 is to get it filled and dosage adjustment state.When motor 5 is inverted, compression body 9 will to the right move drive push rod
14th, piston 1, compression spring 15, pin the side shiftings to the right in the lump such as 13.Negative pressure, medicine can be formed in motion process Chinese medicine tube wall 2
Will be entered into pencil wall 2 by the aperture in the front end of pencil wall 2.The step on the left side of push rod 14 is formd with shell 3 simultaneously
One gap.The size in gap is determined by the dosage for needing injection.
If necessary to drug for injection, it is necessary to press button 11, button 11 is moved to the left, steel ball is coming from pushing away for push rod 14
Entered under power effect in the groove of button 11.Push rod 14 is no longer fettered by steel ball 10, fast in the presence of compression spring 15
Speed is moved to the left.The elastic force of compression spring 15 is acted on the medicine in pencil wall 2 by push rod 14 and piston 2, makes medicine fast
Speed is ejected, and is expelled in vivo.One course of work is completed, the state for returning to accompanying drawing 1 of needleless injector.
