A kind of cut-off diversion mechanism for infusion apparatus woven hose
Technical field:
The present invention relates to the technical fields of medical instrument, are specifically related to a kind of cut-off shunting for infusion apparatus woven hose
Mechanism.
Background technology:
Infusion apparatus is a kind of common medical equipment, and infusion apparatus passes through aseptic process, is established logical between vein and liquid
Road is used for venous transfusion.Infusion apparatus is generally by intravenous needle or injection needle, needle-covering cap, infusion tube, liquid medicine filter, flow velocity
Several part connection compositions such as adjuster, drop pot, bottle plug puncture unit, air filter.Current infusion apparatus is generally only arranged one
A bottle plug puncture unit, and, often there are multiple hanging bags in while being infused, needs to extract bottle plug puncture unit into empty hanging bag when replacing hanging bag, then
It is plugged into new hanging bag, but its bottle plug puncture unit is easily contaminated during extraction, to propose whether can be arranged
Multiple bottle plug puncture units are matched with corresponding hanging bag, to just need to design corresponding cut-off part flow arrangement.
In view of the above shortcomings, the designer, is actively subject to research and innovation, to found, one kind is new structural to be used for
The cut-off diversion mechanism of infusion apparatus woven hose makes it with more the utility value in industry.
Invention content:
The purpose of the present invention aims to solve the problem that problem of the existing technology, provides one kind and can avoid wearing bottle stopper in infusion
It pierces device and extracts hanging bag, realize the cut-off diversion mechanism for infusion apparatus woven hose for switching single hanging bag infusion.
The present invention relates to a kind of cut-off diversion mechanisms for infusion apparatus woven hose, including by disk, be molded over the circle
The distributary base of several spokes and the lasso composition for being molded over the spoke outer end on disk outer wall, the inner end molding of the lasso
There is the first slot, the second slot being connected to first slot is formed in spoke, is formed on the lateral wall of disk and institute
The third slot for stating the connection of the second slot, is plugged with stopper rod in the third slot and the second slot, and the one of the stopper rod
End forms circular cut-off block, and the cut-off block is plugged on that lasso is interior and matched with the inner wall of lasso, stopper rod it is another
End is plugged in third slot and forms boss, the cut-off boom end of the boss surrounding against there is compression spring, the compression spring
Both ends are born against on the inner wall of stopper rod and third slot;
The guide groove of bar shaped is formed on the upper surface of the spoke, the guide groove is connected to the second slot, stopper rod
On form the guide rod being plugged in guide groove, the front end of the guide rod forms the first positioning ball, first positioning
The first notch is formed on ball, the upper surface center of disk is plugged with column spinner, the second positioning ball is formed on the column spinner,
The second notch corresponding with first notch is formed on the second positioning ball, second notch is equipped with magnet
Piece, the first notch can be adsorbed on the flat thin magnet.
By above-mentioned technical proposal, in the use of the present invention, each woven hose with bottle plug puncture unit and hanging bag is inserted
It is connected in each lasso, cut-off block presses woven hose under the action of compression spring, realizes that woven hose is closed.And it is oriented to by stirring
Bar makes the first positioning ball be moved to disk, while rotating column spinner and making the second positioning ball is gone to position ball pair with target first
The position answered, then moves on guide rod, until the first notch of the first positioning ball is adsorbed on the second of the second positioning ball and cuts
On mouth, to realize that the limit to stopper rod, stopper rod have one end of boss to compress compression spring, cut-off block is released to woven hose
The release shunting of woven hose is realized in pressure holding.
Through the above scheme, the cut-off diversion mechanism for infusion apparatus woven hose of the invention can avoid bottle plug puncture unit
Hanging bag is extracted, realizes and switches single hanging bag infusion.
As a preference of the above scheme, the support slot of annular, the second positioning are formed on the upper surface of the disk
The bottom surface of ball forms supporting rod, and the lower end of the supporting rod is plugged in the support slot.
As a preference of the above scheme, it forms on the inner wall of the third slot and to coordinate with the boss of stopper rod
One end of groove, compression spring is resisted against on the third slot inner wall of the groove surrounding.
As a preference of the above scheme, first slot is arc-shaped, and the circular arc radian of the first slot is more than half
Round circular arc radian.
As a preference of the above scheme, second slot runs through the left and right sidewall of spoke.
As a preference of the above scheme, the guide groove on the spoke is parallel with stopper rod.
Above description is only the general introduction of technical solution of the present invention, in order to better understand the technical means of the present invention,
And can be implemented in accordance with the contents of the specification, below with presently preferred embodiments of the present invention and after coordinating attached drawing to be described in detail such as.
