Without further limitation, an element defined by the phrase "comprising a … …" does not exclude the presence of another identical element in a process, method, article, or apparatus that comprises the element.

The features and properties of the present invention are described in further detail below with reference to examples.

The utility model discloses a medical treatment is with intestinal cannula's embodiment one:

the structure of the medical intestinal canal cannula of the present embodiment is shown in fig. 1, and includes a main tube body 1, the main tube body 1 is a plastic tube body with a certain softness, and a lubricating liquid is sprayed on the outer surface thereof. The front end (i.e. the right end in the figure) of the main pipe body 1 is embedded and connected with a front end head 2, the front end head 2 plugs the front end port of the main pipe body 1, and a filling hole 10 which radially penetrates through the pipe wall is arranged at the position close to the front end of the main pipe body 1. The front end head 2 is of a hemispherical structure, and the hemispherical front end head 2 is connected with the main pipe body 1 in an embedded mode through a circular plane of the hemispherical front end head so that the ball head faces forwards. The concrete scarf joint is that the front end ring face of the main pipe body 1 is provided with a ring groove, the circular plane of the hemispherical front end head 2 is provided with a convex ring, and the convex ring is embedded in the ring groove and is fixedly connected with the convex ring and the ring groove through adhesive liquid.

The diameter of the hemisphere front end 2 is equal to the diameter of the main pipe 1, so after the front end 2 is connected to the front end of the main pipe 1, its peripheral surface is in smooth butt joint with the peripheral surface of the main pipe 1, there is no protruding edge and tip. And such front end 2 can make the diameter of hemisphere face as big as possible, and the camber of hemisphere face is less, when intestinal cannula front end inserts in patient's intestinal, is difficult for causing the fish tail to the intestinal mucosa.

The rear end (that is, the left end shown in the figure) of the main pipe body 1 is fixedly connected with a connecting pipe section 11, the inner cavity of the connecting pipe section 11 is communicated with the inner cavity of the main pipe body 1, the connecting pipe section 11 is used for externally connecting a filling container, so that hydraulic pressure in the filling container can enter the main pipe body 1 through the connecting pipe section 11 and can be filled into a patient body through a filling hole 10. The connecting tube section 11 is preferably a flexible rubber tube section to facilitate a sealed connection with the filling container. Of course, in other embodiments, the connecting pipe section 11 may also be a rigid pipe section, on which a threaded connecting section is provided, by which it is sealingly connected to the filling container.

Be responsible for filling hole 10 on the body 1 and have two, and two filling holes 10 set up respectively in the looks of being responsible for the body 1 side of the back of the body, and two filling holes 10 stagger in the axial, can comparatively evenly fill the liquid medicine in to patient's intestinal through filling hole 10 like this.

In addition, the intestinal canal cannula also comprises a bag-shaped protective film 3, and the protective film 3 is a plastic film. Protection film 3 from preceding suit backward is in the outside of being responsible for body 1 and with preceding end 2 and be responsible for including body 1 parcel, protection film 3 plays on the one hand and is responsible for the effect that 1 surface of body was by fish tail, pollution in the packing transportation, plays the lubricated liquid of parcel in addition, avoids the effect of lubricated liquid loss before intestinal intubate uses. Preferably, the opening of the bag-shaped protective film 3 is wrapped with a rubber band which can be contracted and tightly held on the outer peripheral surface of the main pipe body 1 to seal the lubricating liquid therein.

The intestinal cannula is used in the medical treatment of this embodiment, connects the filling container on connecting tube section 11, then takes off protection film 3, inserts patient's intestinal forward with preceding end 2 in, then exerts pressure through gravity or to the filling container and makes the liquid medicine pass through filling hole 10 and get into patient's intestinal in, and whole use is difficult for causing the damage to patient's intestinal mucosa.

The utility model discloses still provide medical treatment with embodiment two of intestinal cannula, embodiment two compare the embodiment one that introduces above and have new structure and new function. As shown in fig. 2, in the present embodiment, different from the above-described embodiment, the connection pipe section 11 is further connected with a pressing structure. The pressurizing structure is used for inflating and pressurizing the main pipe body 1 so as to completely extrude residual liquid medicine in the main pipe body 1 into the patient body, and waste of the liquid medicine can be avoided. Specifically, as can be seen clearly from the figure, the pressurizing structure comprises an air guide hose 40, one end of the air guide hose 40 is detachably connected to the connecting pipe section 11, the other end of the air guide hose is connected with a manual inflation balloon 41, so that one side of the connecting pipe section 11, which faces away from the front end 2, is plugged, when the manual inflation balloon 41 is continuously held, the main pipe body 1 can be inflated and pressurized, and then the main pipe body 1 is extruded with the residual liquid medicine in the main pipe body 1. The manual inflatable balloon 41 is a mature product, and is commonly used in mercury column type blood pressure meters, and the structure thereof will not be described in detail. The air guide hose 40 is preferably connected to the front end of the connecting pipe section 11, so that when the air guide hose is pressurized, the air pressure can more rapidly act on and squeeze out the residual liquid medicine in the main pipe body 1, and the effect is better. And a pouring hole 10 is provided at a front end position of the main tube 1 in order to completely extrude the remaining liquid medicine.

Of course, the medical intestinal cannula of the present invention is not limited to the two embodiments described above, and in other embodiments, unlike the first embodiment described above, the front end is a half of an ellipsoid head, and is another plastic head, such as a PP head or a PC head or a PE head; or, in other embodiments, the pressurizing structure may include a micro air pump, and the micro air pump is detachably connected to the connecting pipe section through an air guide hose; or the pressurizing structure comprises a syringe which is connected to the connecting pipe section through an air guide hose.

The above description is only for the preferred embodiment of the present invention, and the present invention is not limited thereto, the protection scope of the present invention is defined by the claims, and all structural changes equivalent to the contents of the description and drawings of the present invention should be included in the protection scope of the present invention.
