Description
Technical field
The present invention relates to medicine and technical field of medical instruments, is a kind of needleless injector with electric functions.
Background technology
Needleless injector is a kind ofly by external power supply, to liquid drug, to pressurize, and make liquid drug with the form of high-voltage high-speed by very thin micropore, transdermal, enters into a kind of equipment in body.Liquid drug can directly not penetrate human or animal's skin by syringe needle and enter in body.
Along with the development of pharmaceuticals industry, produced many biological preparation quasi drugss, the feature of these medicines is that injection volume is little, often injection.There is the syringe of pin to bring the pain to the fear of pin and acupuncture to user.Needleless injector can have been avoided these problems effectively.Needleless injector can also make injectable drug more be tending towards disperseing simultaneously, is conducive to the absorption of medicine and reduces hypodermic infringement, avoids forming scleroma.
Existing needleless injector mainly contains many weak points.
1, the basic armrest of civilian needleless injector moves to needleless injector pressurization, and user uses inconvenience.
2, the length of existing electric needleless injectors is long, uses inconvenience.
Along with the development needleless injector of technology should be able to reach electronic getting it filled, electronic injection, display screen dose indicating and carry out communication with the external world, so that injected dose and tabulate statistics inject time and send to the function of formulating position.
Summary of the invention
The object of this invention is to provide a kind of needleless injector with electric functions, the power resources that it can be got it filled and inject to needleless injector by the electronic mode of built-in motor, reliable operation, easy to use, volume is little.
For achieving 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), compression spring (15), it is characterized in that: this compression body is tubular structure, in the lateral wall of compression body (9), be vertically extended with a screw (16), on this screw, be socketed with screw mandrel (8), one end of this screw mandrel is connected with motor shaft (6); The other end of this screw mandrel is connected with the one end of shell (3); The axis of push rod (14) is parallel with the axis of motor shaft (6).
The rotating shaft of the screw mandrel other end (4) is rotationally connected by bearing (7) with shell (3).
This needleless injector built-in motor, motor is connected with screw mandrel.Electric machine rotation will drive screw mandrel to rotate, and the rotation of screw mandrel can drive the female thread screw that has being enclosed within on screw mandrel to move.The movement of compression body will Compress Spring.When spring-compressed arrives certain position, the steel ball on the compressed body of the push rod of spring inner meeting is locked.Push rod is by after locked, and motor reverse rotation will drive push rod and piston to reverse movement, reaches the object of drawing medicine and adjusting injected dose.
The position of moving according to the different compression body of the dosage of setting is different.After compression body stops, with hands, just press the button and can inject.
The axis of push rod of the present invention is parallel with the axis of motor, compares the length that can shorten needleless injector with coaxial structure.Its inner motor arranging, can accurately control the startup of motor and stop and rotating and reverse.
The invention has the beneficial effects as follows: the power resources that it can be got it filled and inject to needleless injector by the electronic mode of built-in motor, reliable operation, easy to use, volume is little.

The specific embodiment
Shown in accompanying drawing: 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, compression spring 15, this compression body is tubular structure, in the lateral wall of compression body 9, be vertically extended with a screw 16, on this screw, be socketed with screw mandrel 8, one end of this screw mandrel is connected with motor shaft 6; The other end of this screw mandrel is connected with one end of shell 3; The axis of push rod 14 is parallel with the axis of motor shaft 6.
Rotating shaft 4 and the shell 3 of the screw mandrel other end are rotationally connected by bearing 7.
Accompanying drawing 1 is earth pressure release state, and piston 1 is positioned at pencil wall 2 and plays the effect that seals medicine when getting it filled and injecting.What be connected with piston 1 is push rod 14, and the outer surface cover of push rod 14 has compression spring 15, and the rear end sidewall of push rod 14 is provided with groove 17, and steel ball 10 can embed in this groove 17.The front end of compression spring 15 contacts with the push rod boss 18 of push rod 14, and the rear end of compression spring 15 contacts with interior of compression body 9.Compression body 9 can move axially and compression and movement pressure spring 15.The screw 16 that compression body 9 connects has female thread, and female thread and screw mandrel 8 screw.The rotation of screw mandrel 8 can drive screw 16 to move axially.Screw mandrel 8 is connected with motor 5, and when motor 5 rotates, screw mandrel 8 can together rotate.
Accompanying drawing 2 is pressurized state.When syringe need to be worked, touch switch button 19, motor 5 can rotate, and drives screw mandrel 8 to rotate, and the rotation of screw mandrel 8 can drive compression body 9 to be moved to the left by screw thread.Push rod 14 right-hand members are near lock 13, and promote lock 13 compression button springs 12, when moving to certain position steel ball 10, can enter in the groove 17 of push rod 14 right-hand members, and button 11 outwards ejects under the effect of button spring 12.The platform of button 11 ends has been pressed in steel ball 10 in the groove of push rod 14 right-hand members.Thereby push rod 14 and compression body 9 are locked together.
Accompanying drawing 3 is for getting it filled and dosage adjustment state.When motor 5 reversions, compression body 9 will move to the right and drive push rod 14, piston 1, Compress Spring 15, pinning 13 etc. to move to the right in the lump.Motor process Chinese medicine tube wall 2 is interior can form negative pressure, and medicine will enter in pencil wall 2 by the aperture at pencil wall 2 front ends.Step and the shell 3 on push rod 14 left sides have formed a gap simultaneously.The dosage that the size in gap is injected by needs determines.
If need drug for injection, need to press the button 11, button 11 is moved to the left, and steel ball enters in the groove of button 11 under the thrust that comes from push rod 14.Push rod 14 is no longer subject to the constraint of steel ball 10, under the effect of compression spring 15, is moved to the left rapidly.The elastic force of compression spring 15 acts on the medicine in pencil wall 2 by push rod 14 and piston 2, and medicine is ejected rapidly, is expelled in body.A work process completes, the state of getting back to accompanying drawing 1 of needleless injector.
The above is preferred embodiment of the present invention and the know-why used thereof; for a person skilled in the art; in the situation that not deviating from the spirit and scope of the present invention; the apparent changes such as any equivalent transformation based on technical solution of the present invention basis, simple replacement, within all belonging to protection domain of the present invention.
