Detailed description of the invention
Embodiment: as shown in figs. 1-7, this utility model provides a kind of specific embodiment with the infusion pump of rotation lock, it comprises: the medicine box 10 of collecting medicinal fluid bag, be fixedly connected on medicine box 10 upper end and be convexly equipped with the cover plate 11 of latch part 110, to be arranged on above cover plate 11 and to allow the frame 12 that latch part 110 is passed, be fixedly installed on frame 12 both sides and the front Rear housing half 13 mutually fastened, accommodated by front Rear housing half 13 and can with the rotating shaft 21 of latch part 110 snap fit, allow the fixed mount 22 that rotating shaft 21 partially passes through, the frame 22 that is fixed accommodate and can the lock hook part 23 that promotes by rotating shaft 21, drive the key that rotating shaft 21 rotates, the steady pin 24 that rotating shaft 21 stops the rotation can be made, and make lock hook part 23 adverse movement and be set in the elastic component 25 of rotating shaft 21 one end.Its Chinese medicine box 10 and cover plate 11 are connected for ultrasonic bonding and form kit of parts, and front Rear housing half 13 is provided with the locating slot 130 of collecting fixed mount 22; Frame 12 is wriggling metal machine frame, and is fixedly connected with pump head component (not shown), and is provided with the perforation 120 allowing latch part 110 to pass.Cover plate 11 comprises the latch part 110 protruded and arrange, and latch part 110 center is provided with perforate, and perforate is provided with an inclined-plane 112, and the incline direction on inclined-plane 112 is obliquely.Elastic component 25 is preferably spring.
The axis hole 210 that rotating shaft 21 comprises spindle nose 212, is arranged on spindle nose 212 and allows steady pin 24 to insert, and the eccentric 214 that with spindle nose 212 be axially connected adjacent with axis hole 210, one end is connected with eccentric 214 axis and diameter is greater than the link of eccentric 214 and is positioned at the axially outer end of the link other end, and wherein axially outer end is provided with the keyhole coordinated with key.
Fixed mount 22 comprise allow rotating shaft 21 to partially pass through through hole 220, the inner chamber 222 be connected with through hole 220, to be connected with inner chamber 222 also can with the first groove 224 of steady pin 24 snap fit and be connected with inner chamber 222 also can with the second groove 226 of steady pin 24 snap fit, wherein there is angle at circumferencial direction in the first groove 224 and the second groove 226, and this angle is preferably right angle.
Lock hook part 23 is L-type and comprises snap fit 230, to be positioned at above snap fit 230 and the perforation 232 allowing rotating shaft 21 to partially pass through, snap fit 230 has the skewed surface coordinated with inclined-plane 112 at least, perforation 232 allows spindle nose 212 and eccentric 214 to pass, and do not allow link to pass, through hole 220 then allows link pass and stop axially outer end to pass, namely the diameter of perforation 232 is greater than the long end diameter of eccentric 214, and being less than the diameter of link, the diameter of through hole 220 is then greater than the diameter of link and is less than the diameter of axially outer end.
As illustrated in figures 4-5, during locking, insert in rotating shaft 21 with key, Level Promoting rotating shaft 21 axially-movable, namely move to locking direction, and oppress elastic component 25 and shrink, and steady pin 24 is deviate from after the coordinating of the second groove 226, now snap fit 230 press-in of lock hook part 23 enters inside the inclined-plane 112 of cover plate 11, rotate 90 degree to locked position, now steady pin 24 is pressed in the first groove 224 of fixed mount 22 by elastic component 25, rotating shaft 21 is in self-locking state thus, because rotating shaft 21 contacts part for the long end of eccentric 214 with perforation 232, therefore complete fastening locking medicine box can be realized, even if perforation 232 sizes exceed its margin of tolerance, only be less than the offset of eccentric 214, the reliable locking of medicine box can both be ensured.
As shown in fig. 6-7, during unblock, with key turns rotating shaft 21 to unlocked position, elastic component 25 is in compressive state always, is then pressed in the second groove 226 of fixed mount 22 by steady pin 24, makes rotating shaft 21 be in self-locking state, and rotating shaft 21 contacts part for the short end of eccentric 214 with perforation 232, rotating shaft 21 drives lock hook part 23 thus, and snap fit 230 is departed from and the coordinating of inclined-plane 112, now can more box for changing fresh dressing for wound.
This utility model is infused under effectively preventing producing unadjusted gravity because the maloperation of Non-medical-staff causes infusion pump kit of parts accidentally to get loose in infusion process, avoids patient's grievous injury or death.Manufacture and maintenance cost can be reduced simultaneously, improve product economy.
Certain above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations of doing according to the spirit of this utility model main technical schemes or modification, all should be encompassed within protection domain of the present utility model.
