Description

A kind of medical multi-chamber room conduit

Technical field

The utility model is related to a kind of conduit and in particular to a kind of medical multi-chamber room conduit.

Background technology

At present, market there are a variety of medical catheters, medical catheter is for medical tubular rubber product, can be divided into outer With using with internal, 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 list by structure again Lumen 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.

In the prior art, most of conduits are all single lumen catheters, therefore, when being heated to the liquid in conduit, need In addition to fill the conduit of hot liquid or the water bottle equipped with hot liquid is fitted with transfusion catheter, by the hydrothermal solution in heating duct Or in water bottle hydrothermal solution heat transmission to transfusion catheter so that the fluid temperature in transfusion catheter raises.

But, because transfusion catheter has certain length, even making the liquid after heating, when being input in patient body Heat scatters and disappears also can be than very fast it is impossible to enough make liquid reach preferable heating effect, and said method also results in conduit simultaneously The uneven problem of interior medicine liquid heating is 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 medical multi-chamber room conduit is provided, liquid can be carried out sufficiently and uniformly add Heat.

To achieve these goals, the utility model provides following technical scheme：

A kind of medical multi-chamber room conduit, including catheter body, main chamber, secondary chamber and heating chamber；Main chamber room Section is diamond, and is located at catheter body bottom, and the section of described secondary chamber is ellipse, and is located above main chamber, institute The section stating heating chamber is circle, and symmetrically shape is arranged in the left and right two ends at position between main chamber and secondary chamber, described Tube wall between main chamber and secondary chamber is the first tube wall, and the tube wall between main chamber room and heating chamber is the second tube wall, Tube wall between described secondary chamber and heating chamber is the 3rd tube wall, and the thickness of described first tube wall is more than the thickness of the second tube wall Degree.

Further, it is provided with arc transition angle at the internal wall transitions of main chamber room.

Further, the thickness of described first tube wall is 0.4 millimeter to 0.6 millimeter.

Further, the thickness of described second tube wall is 0.2 millimeter to 0.35 millimeter.

Further, the thickness of described 3rd tube wall is 0.3 millimeter to 0.5 millimeter.

Further, described catheter body is soft rubber material.

The beneficial effects of the utility model are：1st, it is provided by heating chamber, can be to main chamber in conduit and secondary chamber Interior liquid is heated, and homogeneous heating, and heat transference efficiency is high；2nd, conduit terminal with compact integral structure, practical.

Brief description

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 medical multi-chamber room conduit, including catheter body 1, main chamber 2, secondary chamber 3 and heating chamber Room 4；The section of main chamber room 2 is diamond, and is located at catheter body 1 bottom, and main chamber room 2 is used for transmitting liquid, institute The section stating secondary chamber 3 is ellipse, and is located above main chamber 2, and described secondary chamber 3 is used for transmitting another kind of liquid, described The section of heating chamber 4 is circle, and symmetrically shape is arranged in the left and right two ends at position between main chamber 2 and secondary chamber 3, described Heating chamber 4 is used for transmitting hot liquid, thus heating to the liquid in main chamber 2 and secondary chamber 3, main chamber room 2 with Tube wall between secondary chamber 3 is the first tube wall 5, and the tube wall between main chamber room 2 and heating chamber 4 is the second tube wall 6, described Tube wall between secondary chamber 3 and heating chamber 4 is the 3rd tube wall 7, and the thickness of described first tube wall 5 is more than the thickness of the second tube wall 6 Degree, for ensureing the transmission efficiency of heat.

It is provided with arc transition angle 8, described arc transition angle 8 can ensure main chamber at the internal wall transitions of main chamber room 2 The circulation of room 2 Chinese medicine liquid, and the convenient processing of conduit can be made.

The thickness of described first tube wall 5 is 0.4 millimeter to 0.6 millimeter.

The thickness of described second tube wall 6 is 0.2 millimeter to 0.35 millimeter.

The thickness of described 3rd tube wall 7 is 0.3 millimeter to 0.5 millimeter.

Described catheter body 1 is soft rubber material.

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.
