Abstract
The utility model provides a transfusion system is with connecting, includes the connector, the connector cup joints the hose outward, connector and hose coupling part's connector wall is along with to extending in the hose, and its internal diameter is the grow gradually, and the internal diameter in its bosom equals soft bore of pipe basically. Compare with prior art, adopt above -mentioned technical scheme, the utility model discloses can solve outside the bonding firmness problem of product itself, the utility model discloses compare with the disposable infusion utensil of conventional use clinically, it is connected the back with precision filter or dropping funnel, the infusion utensil inserts behind the medicine bottle, the liquid medicine flows in in filter or the dropping funnel, because in the same direction as smooth no step between connector lower extreme inner wall and hose, liquid is suitable and lower, can not produce the torrent phenomenon, it remains just also not have the air between hose and connector, and then solved it and be connected position bubble problem, patient and medical personnel need not the anxious intraductal problem that persists the bubble again, make things convenient for medical personnel convenient operation, increase its work efficiency.
Description
Technical field
The utility model belongs to single use medicine equipment, relates in particular to a kind of transfusion device joint.
Background technology
At present in domestic production disposable infusion set product, mainly by protective sleeve for bottle stopper puncture outfit, bottle plug puncture unit,
Air cleaner, infusion tube, dropper, dropping funnel, accurate filter, flow regulator, bottom hose, band Rule connector two lead to and
Intravenous infusion needle forms, and the connected mode between each accessory has using outer bonding conduit and two kinds of interior bonding conduit, such as Fig. 2, adopts
Interior bonding conduit mode, it is connected on inside connector 3 in flexible pipe 2, this product flexible pipe 2 and the degree of being connected firmly of connector 3 reach not
To product requirement, such as tpe transfusion device；As Fig. 1, using outer bonding way, flexible pipe 2 is socketed in outside connector 3, connector 3
It is step-like with inside flexible pipe 2 junction 38, easily form one section of bubble in interface, particularly under dropping funnel lower end and filter
End, is more easy to retain the lower section in its interface for section air, until when inserting second bottle, that section of air can move down with liquid, very again
To flowing in human vein, bring panic at heart to patient；These are all the problems that current transfusion device exists.
Utility model content
The purpose of this utility model is to provide one kind can automatically exclude remaining between pipeline upper binding head after infusion
The infusion connector of gas, solves existing transfusion device pipe internal memory and leaves a blank the technical problem of gas column.
For achieving the above object, the utility model adopts the following technical scheme that
A kind of transfusion device joint, including connector 3, the outer socket flexible pipe 2 of connector 3, described connector 3 is with flexible pipe 2 even
The connector wall 37 that socket part is divided extends with into flexible pipe 2, and its internal diameter becomes larger, and its innermost internal diameter is substantially equal to soft
The internal diameter of pipe 2.
Described connector 3 is extended along the conical surface with the internal diameter of the connector wall 37 of flexible pipe 2 coupling part.
The internal diameter of the connector wall 37 of described connector 3 and flexible pipe 2 coupling part is along surface extending.
Described connector 3 and accurate filter 1 are integrally formed.
The material of described flexible pipe 2 is tpu or pvc.
Compared to the prior art, using technique scheme, the utility model can solve the bonding firmness of product itself
Outside problem, the utility model compared with clinically conventional use of disposable infusion set tool, its with accurate filter or
Dropping funnel connect after, infusion set insertion medicine bottle after, in liquid inflow filter or dropping funnel, due to connector lower end inner wall with soft
Smooth no step between pipe, liquid along and under, will not turbulization phenomenon, between flexible pipe and connector also just no air residual, and then
Solve its position air bubble problem that is connected, patient and medical personnel need not worry to retain the problem of bubble again in pipe, convenient doctor
Shield human users are convenient, increase its operating efficiency.

Specific embodiment
As Fig. 3, a kind of transfusion device joint, including connector 3, the outer socket flexible pipe 2 of connector 3, connector 3 and flexible pipe 2
The connector wall 37 of coupling part extends with into flexible pipe 2, and its internal diameter becomes larger, and its innermost internal diameter is substantially equal to
The internal diameter of flexible pipe 2.
So design, seamlessly transit from connector to flexible pipe, eliminate the step-like transition in gluing outside prior art, solve
The hidden danger of bubble may be produced.
Connector 3 is extended along the conical surface with the internal diameter of the connector wall 37 of flexible pipe 2 coupling part, now inside its axial cross section
For straight line.
As Figure 10, the internal diameter of the connector wall 37 of connector 3 and flexible pipe 2 coupling part is along surface extending, now its axial direction
It is camber line inside section.
The material of flexible pipe 2 is tpu(thermoplastic polyurethanes, and Chinese is thermoplastic polyurethane bullet
Gonosome rubber) or pvc(pvcpolyvinyl chloride, Chinese is polyvinyl chloride).
This connector can apply to accurate filter, as shown in Figure 4 and Figure 5, the top of connector 3 and accurate filter
The interpolation type connector 1-3 strong bond of 1 lower end, the bottom of connector 3 and flexible pipe 2 strong bond, connector 3 and with flexible pipe 2
During junction not wall built-up and form air column and remain in interface, thus solving the problems, such as gas column, further, since flexible pipe is with transfusion even
The outer connection of joint, also can solve the problems, such as product degree of being connected firmly simultaneously.
As shown in Figure 8 and Figure 9, connector 3 and accurate filter 1 are integrally formed, and are then connected with flexible pipe 2, equally above-mentioned
Problem.So can reduce by a part, an operation of assembling can be reduced.
This connector can apply to dropping funnel, as shown in Figure 6 and Figure 7, inserts firmly in the top of connector 3 and dropping funnel 4 lower end
Adhere and connect, bottom and flexible pipe 2 strong bond of transfusion connector 3, the endoporus of transfusion connector lower port 3-1 endoporus and flexible pipe 2
Smooth, make the liquid flowing out from dropping funnel liquid outlet flow through transfusion connector 3 and during with flexible pipe junction not wall built-up and form air
Post remains in interface, thus solving the problems, such as gas column, further, since flexible pipe and the outer connection of transfusion connector, also can solve simultaneously
Determine the problem of product degree of being connected firmly, the particularly problem of tpe transfusion device degree of being connected firmly.
Embodiment described above is only the preferred embodiments that the utility model connects in infusion set product.Should refer to
Go out, for those skilled in the art, on the premise of without departing from the utility model principle, also can make some modifications and improvement,
This is also regarded as belonging to protection domain of the present utility model.
