Abstract
The utility model discloses a kind of needle tubing, its structure comprises body, suction syringe needle and injecting mechanism, has material hole in the front end of body; In described body front end, rotary suction switch is also installed, is furnished with several suction syringe needles at described rotary suction switching rule; When described body and rotary suction switch relatively rotate, syringe needle rear end involutory or mistake can be closed with described material hole.This utility model structure is simple, convenient for control, and dosing efficiency is effectively improved.
Description
Technical field
This utility model relates to the technical field of medical instruments used in hospital, specifically a kind of pneumatic liquid dispenser.
Background technology
Before patient is infused, need first to carry out drug solution preparing, for many years, drug solution preparing adopts traditional needle tubing manual operations to complete by nurse always, frequent mobile whole needle tubing is needed to adjust needle position to carry out suction operation to the material bottle of diverse location, process is loaded down with trivial details, and holding time is long wastes time and energy, inefficiency.
Utility model content
The purpose of this utility model is just to provide a kind of Multifunctional needle tube, to solve the technical problem that current needle tubing can not meet dosing demand in hospital.
This utility model is achieved in that
A kind of needle tubing, comprises body, suction syringe needle and injecting mechanism, has material hole in the front end of body; In described body front end, rotary suction switch is also installed, is furnished with several suction syringe needles at described rotary suction switching rule; When described body and rotary suction switch relatively rotate, syringe needle rear end involutory or mistake can be closed with described material hole.
Under technique scheme, this utility model can realize like this:
Described suction syringe needle is multiple, and described material hole is one or more.
Described suction syringe needle is two, described material Kong Weiyi.
The pin stalk of described suction syringe needle has several suction mouths successively from root to end direction.
Described suction mouth is three.
This utility model has material hole in the front end of body; Several suction syringe needles that rule is arranged on the rotary suction switch of body front end, when body and rotary suction switch relatively rotate, syringe needle rear end involutory or mistake can be closed with described material hole.This utility model designs structure like this, when needing to carry out suction operation to different material bottles, only body and rotary suction switch need be made to relatively rotate, the material hole of the syringe needle rear end relative with this material bottle and body front end is involutory, can carry out inhaling, noting operation, thus, the suction task to difference material bottle feed liquid is realized expediently.This needle tubing structure is simple, convenient for control, and dosing efficiency is effectively improved.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
Shown in Fig. 1, this needle tubing comprises body 2, is provided with injecting mechanism 3 in body, and the front end of body has material hole 4.Also be provided with rotary suction switch 5 in described body front end, on described rotary suction switch 5, rule is furnished with several suction syringe needles 1.When described body and rotary suction switch relatively rotate, suction syringe needle 1 rear end involutory or mistake can be closed with described material hole 4.
The number of suction syringe needle 1 is determined as required, can be two or more.As required, between suction syringe needle number and material hole number, there is corresponding relation.Under normal circumstances, suction syringe needle number is the twice of material hole number, and two syringe needles are one group, wherein any syringe needle can be selected relative with material hole, to be embodied as right suction, note work by rotating.The most frequently used, suction syringe needle is two, Kong Weiyi, material.As required, also the corresponding material hole of multiple syringe needle or the corresponding multiple material hole of multiple syringe needle can be arranged to, as long as when rotary suction switch and body relatively rotate, a certain or realize involutory or mistake between certain several suction syringe needle and one or several material hole separately and close.
In this utility model, on the pin stalk of suction syringe needle, several suction mouths can be offered successively from root to end direction.By offering the different serial suction mouth in position, the suction under any material level can be realized.So, no matter treat that suction bottle is just being put or is being inverted, all eliminate the trouble that need could complete suction according to material level change adjustment needle position smoothly.Under normal circumstances, described suction mouth is three.
For the needle tubing in two syringe needles, a material hole, work process of the present utility model is described below: rotary suction switch 5 is relatively rotated with body 2, in two suction syringe needles 1 one is involutory with material mouth 4, and the insertion of its front end is treated that suction bottle A(is generally distilled water bottle), make injecting mechanism 3 pumpback again, the material in material bottle A sucks in needle tubing body by suction syringe needle.Rotary suction switch 5 is made to relatively rotate with body 2 again, make another syringe needle involutory with material mouth, and its front end is inserted material bottle B to be mixed, now, control injecting mechanism 3, make piston valve core be pushed forward, the material in needle tubing is pushed in material bottle B to be mixed by suction syringe needle, realize medicament mixed, complete dosing work.
Claims (5)
