Description
Technical field
The utility model belongs to medical instruments field, in particular to a kind of new intravenous transfusion device.
Background technology
Transfusion device is a kind of conventional medicine equipment, and it is that liquid instilled into dropper that it, which is acted on, then flow to human body by dropper, one
As for, be liquid in dropper bottom, the top of dropper is air, by observe drop in dropper drop speed can determine whether liquid
The speed of human body is flowed into, but existing transfusion device has following defect：When liquid has soon flowed, medical worker or patient need
Give special heed to, it is extremely inconvenient, dangerous during use in order to avoid air intravasation or make the backflow of blood of human body.
Utility model content
The purpose of this utility model is to provide a kind of new intravenous transfusion device, to solve the above problems.
To realize the utility model purpose, the technical scheme used for：A kind of new intravenous transfusion device, including dropping funnel and
Closure puts the bottom on dropping funnel lower ending opening；Drain pipe is connected with the bottom, the upper end connection of dropping funnel is set
There is feed tube；Plug is installed with the dropping funnel, and conical through-hole is offered in the middle part of plug；The conical through-hole it is straight
Footpath tapers into along the flow direction of decoction；Suspension ball is additionally provided with the dropping funnel, and suspension ball is positioned at the top of plug；
Catch is additionally provided with the suspension ball, and tangential direction of the catch along suspension ball is set；It is further fixedly arranged in the dropping funnel
Filter membrane.
Further, the diameter of the suspension ball is more than the minimum diameter of conical through-hole.
Further, the upper end of the dropping funnel is additionally provided with air bleeding valve.
Further, the catch is sheet rubber, and catch is circle, and the diameter of catch is more than the diameter of suspension ball, gear
The diameter of piece is less than the internal diameter of dropping funnel.
Further, the inner surface of the bottom is inner concave.
The beneficial effects of the utility model are,
1st, after the liquid in dropper drips off, suspension ball is pressed in taper under gravity due to no buoyancy, suspension ball
In through hole, make suspension ball that conical through-hole to be fully sealed, avoid the remaining liquid flow of transfusion device complete, also avoid falling for blood of human body
Stream, the transfusion device use more convenient, safety；
2nd, by setting filter membrane in dropping funnel, it can prevent impurity from entering human body, further improve security；
3rd, by being provided with catch on suspension ball, when the medicine company in dropping funnel is excessive, suspension ball is suspended in the table of medicine company
Face, now catch can prevent that the decoction in dropping funnel is excessive effectively by feed liquor blockage.
Brief description of the drawings
Fig. 1 is the structure chart of new intravenous transfusion device provided by the utility model；
Mark and corresponding parts title in accompanying drawing：
1st, dropping funnel, 2, bottom, 3, drain pipe, 4, feed tube, 5, plug, 6, conical through-hole, 7, suspension ball, 8, catch,
9th, filter membrane, 10, air bleeding valve.
Embodiment
The utility model is described in further detail below by specific examples of the implementation and with reference to accompanying drawing.
A kind of shown new intravenous transfusion devices provided by the utility model of Fig. 1, including dropping funnel 1 and closure are put
Bottom 2 on the lower ending opening of dropping funnel 1, bottom 2 are demountable structure with dropping funnel 1, and the openend of bottom 2 is two layers, the lower end of dropping funnel 1
Opening sealing be plugged on bottom 2；Drain pipe 3, entrance point and the bottom 2 of drain pipe 3 are connected with the bottom 2
Endosexine is concordant, and the upper end of dropping funnel 1 is connected with feed tube 4, and the port of export of feed tube 4 is higher than the inner top surface of dropping funnel 1；It is described
Plug 5 is installed with dropping funnel 1, plug 5 is rubber plug, and the middle part of plug 5 offers conical through-hole 6；The taper
The diameter of through hole 6 tapers into along the flow direction of decoction, and the central axis of conical through-hole 6 overlaps with the central axis of dropping funnel 1；
Suspension ball 7 is additionally provided with the dropping funnel 1, and suspension ball 7 is positioned at the top of plug 5；Gear is additionally provided with the suspension ball 7
Piece 8, and tangential direction of the catch 8 along suspension ball 7 is set, center and the suspension ball 7 of catch 8 are fixed；It is also fixed in the dropping funnel 1
Filter membrane 9 is provided with, the bubble and impurity that filter membrane 9 is used in filtering liquid medicine, makes the utility model use safer.
The diameter of the suspension ball 7 is more than the minimum diameter of conical through-hole 6, when the suspension ball 7 is dropped in conical through-hole 6
Effectively conical through-hole 6 can be sealed, avoid air from passing through out of conical through-hole 6.The upper end of the dropping funnel 1 is additionally provided with air bleeding valve
10, air bleeding valve 10 effectively can discharge air unnecessary in dropping funnel 1.The catch 8 is sheet rubber, and catch 8 is circular, catch
8 diameter is more than the diameter of suspension ball 7, and the diameter of catch 8 is less than the internal diameter of dropping funnel 1, the diameter of catch 8 is more than feed tube 4
Diameter, while catch 8 makes the flexibility of catch 8 more preferable using sheet rubber, catch 8 and feed liquor when feed tube 4 needs sealing
The entrance point sealing of pipe 4 coordinates.The inner surface of the bottom 2 is inner concave.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, for this
For the technical staff in field, the utility model can have various modifications and variations.It is all in the spirit and principles of the utility model
Within, any modification, equivalent substitution and improvements made etc., it should be included within the scope of protection of the utility model.
