The utility model relates to a five chamber medical catheter comes to transmit respectively hot fluid through setting up the vice cavity of first pair of cavity and second to liquid medicine to in the main cavity room heats, can make heat transfer even, and is effectual to the heating of liquid medicine.
Description
Technical field
The utility model is related to medical instruments field and in particular to a kind of five chamber medical catheters.
Background technology
At present, market there are a variety of medical catheters, medical catheter is for medical tubular rubber product, can be divided into
External application and internal use, the former is used for various gases, the conveying of liquid；The latter is referred to as medical gum-elastic catheter, can be divided into by structure again
Single lumen catheter and multi-lumen tube.
In Clinical practice, in order to mitigate the misery that patient is subject to, many conduits needs when being infused in operation
Defeated liquid is preheated, makes the liquid being input in patient body as close with the body temperature of human body as possible；But, existing
In technology because conduit be all single lumen catheter so as to infusion heating need separately fill the conduit of hot liquid or equipped with heat
The water bottle of liquid and transfusion catheter fit, and the heat transmission of hydrothermal solution in the hydrothermal solution in heating duct or water bottle is led to transfusion
Pipe, so that the fluid temperature in transfusion catheter raises；But so heat transfer is inefficient, and because transfusion catheter tool
Even having certain length so that liquid after heating, being input to during in patient body that heat scatters and disappears also can be than very fast it is impossible to enough
Liquid is made to reach the effect of obvious heating it is therefore desirable to a kind of new technical scheme is solving this problem.
Utility model content
The purpose of this utility model is：A kind of five chamber medical catheters are provided, solve during transfusion, the heating of transfusion catheter to be asked
Topic.
To achieve these goals, the utility model provides following technical scheme：
A kind of five chamber medical catheters, including the secondary chamber of catheter body, inwall, outer wall, main chamber, the first secondary cavity and second
Room；Main chamber room is located inside catheter body, and described first secondary cavity and the second secondary cavity are respectively positioned on inner wall surface, and described the
Symmetrically shape is arranged at the left and right two ends of main chamber to one secondary cavity, and symmetrically shape is arranged at the upper of main chamber to described second secondary cavity
Lower two ends, described first secondary cavity and the second secondary cavity are provided with circular arc chamfering with the junction of inwall, the described first secondary chamber
The area of section of room is more than the area of section of the second secondary cavity.
Further, all relative to main chamber center between described first secondary cavity and each adjacent secondary cavity of the second secondary cavity
Arrange in 90 degree.
Further, the wall thickness of described first secondary cavity and the second secondary cavity is 0.5 millimeter.
Further, the material of described catheter body is soft rubber.
The beneficial effects of the utility model are：Catheter interior is passed respectively by arranging the first secondary cavity and the second secondary cavity
Defeated hot liquid, thus heating to the liquid in main chamber, can make heat transfer uniformly, good to the heating effect of liquid.
Brief description
Fig. 1 is a kind of axonometric drawing of five chamber medical catheters of the utility model.
Fig. 2 is a kind of cross-sectional view of five chamber medical catheters of the utility model.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, the utility model is described in further detail.It should be appreciated that specific embodiment described herein is only in order to explain this
Utility model, is not used to limit the utility model.
With reference to Fig. 1 and Fig. 2, a kind of five chamber medical catheters, including catheter body 1, inwall 2, outer wall 3, main chamber 4, first
Secondary cavity 5 and the second secondary cavity 6；Main chamber room 4 is located inside catheter body 1, and main chamber room 4 is used for conveying liquid, institute
State the first secondary cavity 5 and the second secondary cavity 6 is respectively positioned on inwall 2 surface, symmetrically shape is arranged at main chamber to described first secondary cavity 5
4 left and right two ends, symmetrically shape is arranged at the upper and lower ends of main chamber 4, described first secondary cavity 5 He to described second secondary cavity 6
Second secondary cavity 6 is used to the hot liquid that circulates, and described first secondary cavity 5 and the second secondary cavity 6 are respectively provided with the junction of inwall 2
There is circular arc chamfering 7, described circular arc chamfering 7 is used for strengthening the bonding strength of the first secondary cavity 5 and the second secondary cavity 6 and inwall 2, with
When can ensure the circulation of main chamber 4 Chinese medicine liquid, the area of section of described first secondary cavity 5 is more than the section of the second secondary cavity 6
Area.
All it is in 90 degree relative to main chamber 4 center between described first secondary cavity 5 and each adjacent secondary cavity of the second secondary cavity 6
Setting, this layout can make the liquid in main chamber 4 be heated evenly.
The wall thickness of described first secondary cavity 5 and the second secondary cavity 6 is 0.5 millimeter, can ensure the first secondary cavity 5 and second
In secondary cavity 6, the heat of hydrothermal solution is sufficiently transmitted to the liquid in main chamber 4.
The material of described catheter body 1 is soft rubber.
Above-described embodiment is used for the utility model is further described, but the utility model is not confined to these
Specific embodiment.All any modification, equivalent and improvement made within spirit of the present utility model and principle etc., all
It is interpreted as within protection domain of the present utility model.
