Description
Technical field
This utility model belongs to technical field of medical treatment mechanical, particularly relates to the needleless injector that a kind of motor compresses.
Background technology
Needleless injector be a kind of by pressure liquid infusion to the syringe in human body.Its concrete grammar: first, tightens the spring of needleless injector; Then, the syringe needle of needleless injector is put into injecting fluid, rotate needleless injector and complete suction medicine; Finally, needleless injector syringe needle is aimed at the position oneself will injected, press release-push and complete injection.
As can be seen here, the shortcoming of common needleless injector has:
(1) holddown spring is painstaking: the power that the spring of needleless injector is required when compressing is very large, and weak patient uses more difficult;
(2) complex operation: inject a required time long.
Summary of the invention
The purpose of this utility model is the deficiency for existing conventional injection system, proposes the needleless injector that a kind of motor compresses.
The needleless injector that motor compresses, comprises motor hold down gag, needleless injector and interface of getting it filled;
Described motor hold down gag comprises motor, ball-screw, feed screw nut, sliding platform; Motor shaft in motor is fixedly connected with ball-screw by shaft coupling, and ball-screw is connected by lead screw pair and feed screw nut, and feed screw nut and sliding platform are fixed;
Needleless injector comprises shell the latter half, main spring, mobile jib, back-moving spring, shell the first half, piston rod and piston bush; Described shell the latter half and shell the first half are all cylindrical structural, shell the latter half open-top, open bottom shell the first half; Shell the first half is connected with shell the latter half by moving sets; Shell the latter half is fixed on sliding platform;
Described piston bush and shell the first half are coaxially arranged, and described mobile jib is arranged in the enclosed space that shell the first half and shell the latter half form, and mobile jib is provided with spacing preiection, and piston rod is arranged on mobile jib top; One end of main spring is fixedly connected with spacing preiection, and the other end is fixedly connected with bottom shell the latter half; One end of back-moving spring is fixedly connected with spacing preiection, and the other end is fixedly connected with shell the first half top, and described shell the latter half is provided with retaining mechanism, is used for locking mobile jib, and the top of described piston bush arranges interface of getting it filled.
The beneficial effects of the utility model: without the need to artificial energizing spring, are convenient to weak patient and use; Simple to operate; Energizing spring, injected dose has realized automatic control all.

Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail:
As shown in Figure 1, the needleless injector that a kind of motor compresses, comprises motor hold down gag, needleless injector and interface of getting it filled;
As shown in Figure 2, described motor hold down gag comprises motor 1, ball-screw 2, feed screw nut 3, sliding platform 4; Motor shaft in motor 2 is fixedly connected with ball-screw 2 by shaft coupling, and ball-screw 2 is connected by lead screw pair and feed screw nut 3, and feed screw nut 3 is fixed with sliding platform 4;
As shown in Figure 3, needleless injector comprises shell the latter half 5, main spring 6, mobile jib 7, back-moving spring 8, shell the first half 9, piston rod 12 and piston bush 13; Described shell the latter half 5 and shell the first half 9 are all cylindrical structural, shell the latter half 5 open-top, open bottom shell the first half 9; Shell the first half 9 is connected with shell the latter half 5 by moving sets; Shell the latter half is fixed on sliding platform;
Described piston bush and shell the first half are coaxially arranged, and described mobile jib 7 is arranged in the enclosed space that shell the first half and shell the latter half form, and mobile jib 7 is provided with spacing preiection 14, and piston rod is arranged on mobile jib 7 top; One end of main spring 6 is fixedly connected with spacing preiection, and the other end is fixedly connected with bottom shell the latter half 5; One end of back-moving spring 8 is fixedly connected with spacing preiection, and the other end is fixedly connected with shell the first half 9 top, and described shell the latter half is provided with retaining mechanism, is used for locking mobile jib 7, and the top of described piston bush arranges interface 10 of getting it filled.
Referring to Fig. 4, Fig. 5, Fig. 6, Fig. 7, the step that this machine will carry out within a working cycle has:
1, motor 1 rotates forward, and makes sliding platform 4 increase, and waits and rises to shell the latter half 5 when pinning with mobile jib 7, motor 1 stall;
2. medicine bottle 11 is aimed at interface 10 of getting it filled, motor 1 reverses, when waiting drug injection dosage to reach the dosage set, and motor 1 stall;
3. take off medicine bottle 11 and interface of getting it filled, take out needleless injector, needleless injector is aimed at the position of needs of patients injection, press unlock button, medicinal liquid has just been expelled in human body.
Above-mentioned detailed description of the invention is used for explaining and this utility model is described; instead of this utility model is limited; in the protection domain of this utility model claim, any amendment make this utility model and change, all fall into protection domain of the present utility model.
