Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described。
The automatic subcutaneous injection holder of hand held provided by the invention, as shown in Figure 1, Figure 2, Figure 3 shows, including: outer sleeve 1, inner sleeve 2, propeller 3；
The hypomere side of described outer sleeve 1 is provided with open ports, is used for putting into syringe 4；The open ports place of outer sleeve 1 is provided with openable protective cover 101；It is provided with adjustment fixed mechanism 102, for the fixing syringe 4 putting into outer sleeve 1 at outer sleeve 1 hypomere；Regulating fixed mechanism 102 in this example and adopt set screw 1021, the outer end of set screw 1021 connects adjusting knob, inner connection one elastic end 1022；Adjustable screw 1021 is provided with two, is symmetrical set at outer sleeve 1 hypomere；When left and right adjusting screw 102 inwardly regulates, the syringe of syringe 4 can be clamped；Elastic end 1022 adopts Rubber end or other soft material matter to make, and can avoid crushing glass or plastic needle cylinder；In other embodiments, regulate fixed mechanism 102 and may be used without being arranged on the pressure ring etc. of outer sleeve 1 hypomere inwall, as long as the syringe of syringe 4 can be fixed；
Outer sleeve 1 hypomere is provided with scale 103；Outer sleeve 1 hypomere and/or protective cover 101 are transparent；Outer sleeve 1 hypomere top is additionally provided with syringe needle hole 104；It it is no matter the syringe (this type of disposable syringe often self with scale) manually sucking medicinal liquid, or (this type of syringe is a lot of does not have scale above self for the syringe of preset medicinal liquid, what what preset amount of liquid medicine had had more lacks, depending on variety classes medicinal liquid), put into outer sleeve 1 hypomere when syringe 4 to fix, and after syringe needle is completely exposed syringe needle hole 104, by observing the scale 103 on outer sleeve 1, it is known that the length of the syringe herb liquid of syringe 4, and then the haul distance (this haul distance also corresponding propeller 3 needs the haul distance advanced) that the injection handle of syringe 4 needs to advance can be known；
The epimere of outer sleeve 1 is provided with female thread, and inner sleeve 2 is provided with external screw thread, is coordinated by internal and external threads, and by rotating the top of inner sleeve 2, inner sleeve 2 can up-down adjustment walking in outer sleeve 1 after rotating；
Propeller 3 is located in inner sleeve 2；Being provided with guided way 301 along inner sleeve 2 length direction on propeller 3, guided way 301 embeds in the gathering sill 201 arranged on inner sleeve 2 sidewall；So, propeller 3 is under the effect of motor, it is possible to move up and down relative to inner sleeve 2；The lower end of inner sleeve 2 is completely open；Under original state, the lower surface of propeller 3 just flushes with the lower ending opening of inner sleeve 2；After syringe 4 is fixed on outer sleeve 1 hypomere, be rotated down inner sleeve 2, then inner sleeve 2 moves downwardly together with propeller 3, until the lower top of propeller 3 just contacts with the injection handle of syringe 4；
The structure of propeller 3 may be such that and includes a propulsion tube, and propulsion tube both sides set guided way 301；The lower surface of propulsion tube can prop up the injection handle of syringe 4；
Propeller 3 is driven by an automatically controlled driving mechanism that can regulate angle of rake propelling stroke length and adjustment angle of rake promotion time；Before the injection, first automatically controlled driving mechanism is configured, required propelling stroke length (knowing when observing syringe medicinal liquid relative to outer sleeve high scale) and angle of rake promotion time are set；So, propelling stroke length and injection time are just fully controllable；
Automatically controlled driving mechanism is described below:
Battery, MCU, motor-drive circuit, motor 202, screw mandrel 203, feed screw nut 204 it is provided with in inner sleeve 2；The top of inner sleeve 2 is provided with start key 205, haul distance adjusting key 206 and Timing key 207；Inner sleeve 2 epimere side is additionally provided with display screen 208；
Feed screw nut 204 is fixed on propeller 3 upper end；Motor 202 is fixed in inner sleeve 2 above feed screw nut 204；The rotating shaft of motor 202 is connected with screw mandrel 203；Screw mandrel 203 matches with feed screw nut 204；When motor 202 rotates, screw mandrel 203 rotates and propeller about 3 can be driven to move according to setpoint distance and setting time；Guided way 301 on propeller 3 is mutually embedding with the gathering sill 201 on inner sleeve 2 is also prevented from propeller 3 transfer；
As shown in Figure 4, MCU electrically connects start key 205, haul distance adjusting key 206 and Timing key 207 and display screen 208；And connect motor 202 by a motor-drive circuit；Battery is the power supplies such as MCU, motor-drive circuit, display screen 208；
When this injection holder uses,
1), first open protective cover 101, syringe 4 is fixed on hypomere in outer sleeve 1；As shown in Figure 1；
2), close protective cover 101, and then manually twisting rotates inner sleeve 2 so that the related propeller 3 of inner sleeve 2 moves down；The injection handle on the lower top and syringe 4 that are displaced downwardly to propeller 3 just contacts；As shown in Figure 2；Due to protective cover 101 and outer sleeve 1 hypomere, at least one is transparent, and whether the lower top that therefore can carry out observing propeller 3 contacts with the injection handle of syringe；In original state, propeller 3, relative to the position of inner sleeve 2, is positioned at the top, and namely the lower surface of propeller 3 just flushes with the lower ending opening of inner sleeve 2；
3) by the scale of outer sleeve 1 hypomere, observe the length of the syringe herb liquid of syringe 4, the haul distance that propeller 3 needs to advance can be obtained；
4) being arranged the haul distance of propeller 2 by haul distance adjusting key 206, and press doctor's advice and arrange injection time (i.e. the promotion time of propeller 3) by Timing key 207, some medicinal liquid needs slowly injection, and the such as 12 second time injects complete；On display screen 208, observable arranges numerical value；Motor 202 can be driven by MCU according to the numerical value arranged；
5) have an acupuncture treatment；Then press start key 205, injecting liquid drug can be automatically performed。
