Abstract
The utility model discloses an infusion apparatus, which comprises a Murphy,s dropper communicating with a puncture needle via an upper infusion pipe, a syringe needle communicating with the lower end of the Murphy,s dropper via a lower infusion pipe, a lower speed regulator arranged on the lower infusion pipe, two droplet infusion pipes connected in parallel with the two ends of the upper infusion pipe, a droplet infusion dripper which is arranged at the lower ends of the droplet infusion pipes and protrudes inside the Murphy's dropper, and an upper speed regulator arranged on the upper infusion pipe. In order to more stably connecting the upper infusion pipe and the droplet infusion pipe, the upper end of the upper infusion communicates with the upper end of the droplet infusion pipe via a tee joint. The infusion apparatus adopts dual infusion pipes, is suitable for both common infusion and special medicinal liquid infusion with strict requirement for droplet infusion speed, and is especially suitable for intravenous infusion of nitroglycerine, pituitrin and other medicines requiring droplet accurate infusion, or infusion to infants.
Description
Technical field
This utility model relates to medical instruments field, is specifically related to a kind of transfusion device.
Background technology
The present transfusion device that uses clinically, comprise Murphy's burette, the upper end of Murphy's burette is communicated with an end of upper tubing, the other end of upper tubing with go into a bottle puncture needle and be communicated with, going into bottle puncture needle inserts in the medicine bottle of eminence, medicinal liquid just flows in the Murphy's burette by upper tubing, the upper tubing middle part is provided with the speed regulator of control tube for transfusion flow velocity, adjusting the speed regulator knob just can control roughly the transfusion device flow velocity, the lower end of Murphy's burette is communicated with transfusion needle, and medicinal liquid finally enters human body by transfusion needle.This transfusion device Murphy's burette water dropper is thick, dropping liquid is big, flow velocity is fast, about 20/ml, can not satisfy the accurately requirement of transfusion of trace, especially to medicine such as quiet nitroglycerin, pituitrin clinically or give infant transfusion,, will cause beyond thought consequence if dose is excessive or inaccuracy.
The utility model content
The technical problems to be solved in the utility model be at above-mentioned deficiency provide a kind of simple in structure, easy to use, both satisfied the common transfusion requirement, again can trace the accurate transfusion device of transfusion.
For solving the problems of the technologies described above, this transfusion device, comprise Murphy's burette, Murphy's burette through upper tubing with go into a bottle puncture needle and be communicated with, the lower end warp of Murphy's burette tube for transfusion down is communicated with entry needle, and following tube for transfusion is provided with down speed regulator, and its construction features is: be parallel with the microdroplet tube for transfusion at the two ends of upper tubing, the lower end of microdroplet tube for transfusion is provided with the microdroplet transfusion water dropper that extend in the Murphy's burette, and upper tubing is provided with speed regulator.
This transfusion device adopts the design in parallel of two tube for transfusions, both having can be used as general infusion set uses, can be used as accurately transfusion use of trace again, when using as general infusion set, last speed regulator is all opened, medicinal liquid will be infused by upper tubing, the switch size of speed regulator is the may command transfusion speed under regulating, and certainly, also has the sub-fraction medicinal liquid to flow in the Murphy's burette by the microdroplet tube for transfusion, as common transfusion, its influence can be ignored; When accurately transfusion is used as trace, the last speed regulator at upper tubing middle part cuts out, then medicinal liquid will flow in the Murphy's burette by the microdroplet tube for transfusion and accurately infuse, accurately the amount of infusion of transfusion is mainly decided by the microdroplet transfusion head of microdroplet tube for transfusion lower end, when needs reduce transfusion drip speed, the following switch of speed regulator suitably turned down get final product.
As improvement, more firm for the upper tubing upper end is connected with microdroplet tube for transfusion upper end, the upper end of the upper end of upper tubing and microdroplet tube for transfusion is communicated with by threeway.
In sum, this transfusion device is simple in structure, easy to use, both satisfied the common transfusion requirement, again can accurately transfusion of trace, and be particularly suitable for clinical quiet nitroglycerin, pituitrin etc. and need the accurately medicine of transfusion of trace, perhaps give infant transfusion.
Description of drawings
In conjunction with the accompanying drawings this utility model is described in further detail:
Accompanying drawing is the structural representation of transfusion device.
Among the figure: 1 for going into a bottle puncture needle, and 2 are threeway, 3 upper tubings, and 4 is the microdroplet tube for transfusion, 5 is last speed regulator, 6 is the common transfusion water dropper, and 7 is microdroplet transfusion water dropper, and 8 is Murphy's burette, and 9 are following tube for transfusion, 10 is microfilter, and 11 is air inlet pipe, and 12 is air filter, and 13 are following speed regulator.
The specific embodiment
As shown in the figure, this transfusion device comprises Murphy's burette 8, the upper end of Murphy's burette 8 is communicated with the lower end of upper tubing 3, the lower end of upper tubing 3 is provided with common transfusion water dropper 6, the specification of common transfusion water dropper 6 is 20/ml, upper tubing 3 middle parts are provided with the last speed regulator 5 of control tube for transfusion flow velocity, the upper end of upper tubing 3 is communicated with the medicine liquid channel of going into bottle puncture needle 1, the air intake duct of going into bottle puncture needle 1 is communicated with an end of air inlet pipe 11, the other end of air inlet pipe 11 is communicated with air filter 12, like this, the medicinal liquid in the medicine bottle just enters in the Murphy's burette 8 through upper tubing 3 under self gravitation and the atmospheric effect of air.The lower end of Murphy's burette 8 is communicated with the upper end of following tube for transfusion 9, and the lower end of following tube for transfusion 9 is communicated with the medicine-injecting end of entry needle through microfilter 10, and following tube for transfusion 9 is provided with down speed regulator 13.Be parallel with microdroplet tube for transfusion 4 at the two ends of upper tubing 3, specifically, the upper end of upper tubing 3 is communicated with the upper end of microdroplet tube for transfusion 4, both connections realize by threeway 2 in the present embodiment, the lower end of upper tubing 3 is communicated with Murphy's burette 8 side by side with the lower end of microdroplet tube for transfusion 4, the lower end of microdroplet tube for transfusion 4 is provided with microdroplet transfusion water dropper 7, in the present embodiment, the specification of microdroplet transfusion water dropper 7 adopts 100/ml, when the needs trace is accurately infused, adjusted device 5 cuts out fully, then medicinal liquid is only infused by microdroplet transfusion drip tube 4, the microdroplet accurately flow velocity of transfusion is the flow velocity that microdroplet transfusion water dropper 7 is limited, and also is 100/ml, when needs reduce infusion flow rate, the aperture that only need turn down down speed regulator 13 gets final product, when needs stop to infuse, will descend speed regulator 13 to close fully and get final product, very convenient.
