Description

Six cavities conduit pipes

Technical field

The utility model relates to a kind of medical catheter, more particularly, it relate to a kind of be not easily crushed or damage six cavities conduit pipes.

Background technology

At present, there is a variety of medical catheter in market, medical catheter is the tubular rubber goods for medical treatment, can be divided into use in external application and body, and the former is for the conveying of various gas, liquid; The latter is referred to as medical gum-elastic catheter, can be divided into single lumen catheter and multi-lumen tube again by structure.

Single lumen catheter only has an inner chamber, multi-lumen tube is performed the operation for medical surgery, multi-lumen tube is due to the purposes difference in each chamber, and the sectional area in its chamber is also different, some multi-lumen tube structural instability, the outer wall of some chamber major parts is thinner, be crushed after being easily squeezed, make the fluid flow in chamber reduce even to stop, have serious consequences to patient, and the thinner intensity that will make of large-area outer wall is less, outer wall easily damages.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of six cavities conduit pipes being not easily crushed or damaging.

For achieving the above object, the utility model adopts following technical scheme, comprise main chamber, the described main chamber left and right sides is symmetrically arranged with secondary cavity, I-shaped chamber is provided with directly over described main chamber, described I-shaped the chamber left and right sides is provided with circular time chamber, and the inner side of described secondary cavity outer wall is one-body molded reinforced wall, and described reinforced wall is thickening gradually from upper and lower two ends to middle part.

Preferably, the equal rounding in junction inside I-shaped chamber.

Preferably, the equal rounding in the junction inside secondary cavity.

Preferably, the inner wall thickness of main chamber, secondary cavity, I-shaped chamber and circle time chamber is 0.5mm, and outer wall thickness is also 0.5mm.

The utility model hinge structure is compared to be had: secondary cavity outer wall is larger with extraneous contact area, one-body molded within it have reinforced wall, reinforced wall is thickening gradually from upper and lower two ends to middle part, thicken the thickness of outer wall herein like this, six cavities conduit pipes are made to be not easy to be crushed, ensure fluid flow, not easily make outer wall herein damage.

Accompanying drawing explanation

Fig. 1 is six cavities conduit pipe structural representations;

Fig. 2 is six cavities conduit pipe sectional views.

Reference numeral: 1, six cavities conduit pipes, 11, main chamber, 12, secondary cavity, 13, I-shaped chamber, 14, circular time chamber, 2, outer wall, 3, inwall, 4, reinforced wall.

Detailed description of the invention

With reference to accompanying drawing, the utility model six cavities conduit pipe embodiment is described further.

A kind of six cavities conduit pipes, comprise main chamber 11, main chamber 11 left and right sides is symmetrically arranged with secondary cavity 12, I-shaped chamber 13 is provided with directly over main chamber 11, I-shaped time chamber 13 left and right sides is provided with circular time chamber 14, such set-up mode structure is relatively stable, secondary cavity 12 outer wall 2 is larger with extraneous contact area, one-body molded within it have reinforced wall 4, reinforced wall 4 is thickening gradually from upper and lower two ends to middle part, as shown in Figure 2, dotted line place is the position at the place, inner side of original outer wall 2, after having added reinforced wall 4, inner side arrives the solid line place inside dotted line, the total outer wall 2 of secondary cavity 12 obviously thickeies, when depressed, support force and the elastic force of thicker outer wall 2 are larger, not easily make outer wall 2 relatively close, thicken the thickness of outer wall 2 herein like this, six cavities conduit pipes 1 are made to be not easy to be crushed, ensure fluid flow, and not easily make outer wall 2 herein damage.

The equal rounding in junction inside I-shaped chamber 13, radius of corner is 0.4mm to 0.5mm herein, is preferably 0.4mm, facilitates the circulation of liquid in I-shaped chamber 13 like this, not easily make the junction of liquid residue inside I-shaped chamber 13.The equal rounding in junction inside secondary cavity 12, radius of corner is 0.3mm to 0.4mm herein, be preferably 0.3mm, facilitate the circulation of liquid in secondary cavity 12 like this, not easily make the junction of liquid residue inside I-shaped chamber 13, less fillet also can ensure that secondary cavity 12 has certain space.

Inwall 3 thickness of main chamber 11, secondary cavity 12, I-shaped chamber 13 and circle time chamber 14 4 is 0.5mm, outer wall 2 thickness is also 0.5mm, the maximum outside diameter of six cavities conduit pipes 1 is 16.22mm, positive negative error is 0.05mm, such inwall 3 and the thickness of outer wall 2, effectively isolated each adjacent chamber, liquid can not be mixed, and six cavities conduit pipe 1 structures also made are relatively stable.

The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to the above embodiments, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
