A kind of Medical stand for transfusion
Technical field
The present invention relates to technical field of medical equipment more particularly to a kind of Medical stand for transfusion.
Background technology
Be infused also known as have an intravenous drip or hang water, be by intravenous drip input internal large dosage (single administration 100ml with
On) injection, it is packaged in glass or plastic infusion bottle or bag, is free of preservative or bacteriostatic agent, by defeated when use
Liquid device adjustment drop speed, continues and steadily enters vein, to supplement body fluid, electrolyte or provide nutriment, venous transfusion skill
The nearly 500 years setback of the development experience of art, the system of complete set is gradually formed in 20th century, becomes the most frequently used, most directly
One of effective clinical treatment means.Current therapeutic medical infusion device is all very simple, just an only infusion support, infusion when
Waiting patient also wants the moment to observe the liquid medicine amount in infusion bottle, reminds nurse to replace infusion bottle to press alarm switch in time
Or needle is pulled out, but for going for the patient of hospital transfusion alone, when inevitably having sleeping, and nurse is also impossible to one
Quarter ceaselessly patrols back and forth, this is easy for occurring the case where there is blood backflow after liquid medicine is totally lost, for this purpose, it is proposed that a kind of doctor
Treatment is solved the above problems with infusion support.

First rotating shaft 18 is located at the lower section of first connecting rod 13, and sidewall sheath of the first rotating shaft 18 far from the first rotating member 17 is equipped with and third tooth
The side wall of 16 matched second gear 19 of item, first rotating shaft 18 is also arranged with the first helical gear 20, and the lower end inner wall of shell 3 passes through
Second rotating member 21 is rotatably connected to the second shaft 22 being vertically arranged, and the upper end of the second shaft 22 is fixed with and the first helical teeth
20 matched second helical gears 23 are taken turns, the bottom side of the wall of the second shaft 22 is also arranged with third helical gear 24, and the inner wall of shell 3 is logical
It crosses third rotating member 25 and is rotatably connected to the threaded rod 26 being laterally arranged, the one end of threaded rod 26 far from third rotating member 25 is fixed
There is block, and the diameter of block is more than the diameter of nut 28, block can prevent nut 28 from removing threaded rod 26, and threaded rod 26
Sidewall sheath be equipped with and 24 matched 4th helical gear 27 of third helical gear, sidewall sheath of the threaded rod 26 far from the 4th helical gear 27
Equipped with matched nut 28, and the bottom side of the wall of nut 28 is equipped with second connecting rod 29 vertically.
Shell 3 is equipped with second sliding slot 30 close to the lower end inner wall of nut 28, and second connecting rod 29 by the second sliding block 31 with
Second sliding slot 30 is slidably connected, and second connecting rod 29 is transversely provided with third connecting rod 32, and third connecting rod 32 close to the side wall of woven hose 6
One end far from nut 28 is equipped with the first fixed block 33, and the first fixed block 33 is equipped with third sliding slot 34 close to the side wall of woven hose 6,
And third sliding slot 34 slidably connects the first fixed ring 36, inner wall of the shell 3 far from the first fixed ring 36 by third sliding block 35
Equipped with the second fixed block 37, the second fixed block 37 is equipped with the 4th sliding slot 38 close to the side wall of woven hose 6, and the 4th sliding slot 38 passes through
Four-slider 39 slidably connects and 36 matched second fixed ring 40 of the first fixed ring.
When the present invention works, infusion bottle 5 is inverted into hanging block 41, woven hose 6 is inserted into infusion bottle 5, woven hose 6
Between the first fixed ring 36 and the second fixed ring 40, then the second telescopic rod 45 is taken in the first telescopic rod 44, when defeated
After liquid bottle 5 is put into hanging block 41, the first spring 4 is stretched.
With the reduction of 5 Chinese medicine dose of infusion bottle, the elastic force of the first spring 4 is gradually by hanging block 41 toward pull-up, and mandril 7 is to moving up
Dynamic, when the liquid in infusion bottle 5 is totally lost soon, the first rack 10 is engaged with first gear 11, and first gear 11 rotates counterclockwise,
First gear 11 is engaged with the second rack 12, and the second rack 12 moves down, and third rack 16 is engaged with second gear 19, and second
Gear 19 drives first rotating shaft 18 to rotate, and first rotating shaft 18 drives the rotation of the first helical gear 20, the first helical gear 20 and second oblique
Gear 23 engages, and the second helical gear 23 drives the rotation of the second shaft 22, the second shaft 22 that third helical gear 24 is driven to rotate, third
Helical gear 24 is engaged with the 4th helical gear 27, and the 4th helical gear 27 drives threaded rod 26 to rotate, since nut 28 connects by second
Bar 29 is connect with the second sliding block 31, and the second sliding block 31 can only slide in second sliding slot 30, therefore second connecting rod 29 limits
The axial rotation of nut 28, nut 28 can move on it when threaded rod 26 rotates, when the first rack 10 and first
When gear 11 engages, nut 28 starts to drive the first fixed ring 36 close to woven hose 6, when the first rack 10 continues and the
When one gear 11 engages, the first fixed ring 36 gradually withstands on woven hose 6 in second fixed ring 40.
Since hanging block 41 constantly moves up, woven hose 6 is also by with moving up, when the first fixed ring 36
When woven hose 6 is withstood in the second fixed ring 40, the frictional force between woven hose 6 and the first fixed ring 36 and the second fixed ring 40
The two is driven and then to move up, the first fixed ring 36 upward sliding in third sliding slot 34, the second fixed ring 40 is slided the 4th
Upward sliding in slot 38,36 and second fixed ring 40 of such first fixed ring would not hinder the movement of woven hose 6, when mandril 7
Touch alarm by compress switch 9 when, alarm 8 sends out warning reminding nurse to replace infusion bottle, first fixes at this time
Ring 36 and the second fixed ring 40 clamp woven hose 6, and the liquid in woven hose 6 does not circulate still further below, can prevent in woven hose 6
There is vacancy in liquid, and the case where causing blood backflow occurs.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
