Description

Disposable pump milk extension pipe

Technical Field

The utility model relates to the field of medical supplies, specifically speaking relates to a disposable pump milk extension pipe.

Background

The nasojejunal tube is a medical device widely used in the medical community, and is suitable for: patients who need to enter duodenum or jejunum directly through nasal feeding and patients who have gastrointestinal emptying disorder due to basically normal intestinal function so as to directly inject nutritional food into the intestinal tract of the patients for absorption; at present, the nasojejunal tube micropump is not connected with a special large-diameter connecting tube of an injector when pumping milk, so that the nasojejunal tube micropump is not favorable for milk injection, and uses an extension tube for vein, and the extension tube is too thin and is easy to cause milk blockage due to a filter, and meanwhile, a nurse self-modifies a pipeline and also has the risk of causing infection.

SUMMERY OF THE UTILITY MODEL

In order to solve the defects of the prior art, the utility model aims to provide a disposable milk pumping extension tube to overcome the defects in the prior art.

In order to realize the above-mentioned purpose, the utility model provides a disposable pump milk extension pipe, including pipeline, syringe, flow rate ware and sharp mouth ware, the syringe is pegged graft in pipeline one end, and sharp mouth ware is pegged graft at the pipeline other end, and the flow rate ware cup joints outside the pipeline middle part, and wherein, sharp mouth ware includes sharp pipe, sleeve pipe and inner tube, and sharp pipe links firmly in sleeve pipe one side, and the inner tube links firmly in the sleeve pipe, and the inner tube is pegged graft in the pipeline, and the sleeve pipe cup joints outside the pipeline, and sharp pipe one end is three horn shapes, and sharp pipe inserts the empty intestines of nose intraductally.

As a further explanation of the present invention, it is preferable that the distance between the sleeve and the inner tube is smaller than the wall thickness of the pipeline.

As a further explanation of the present invention, it is preferable that the inner tube outside port is a sharp-end port.

As a further explanation of the present invention, it is preferred that the inner tube length is less than the sleeve length.

As a further explanation of the present invention, preferably, the casing is fixedly connected with an annular outer edge, and the outer diameter of the outer edge is larger than the outer diameter of the casing.

As a further explanation of the present invention, preferably, the inner side of the pointed tube is provided with an inner wall, and the inner wall is connected to the inner wall of the inner tube.

The utility model discloses following beneficial effect has:

the utility model discloses a combine present articles for use in clinical, make the new disposable connecting pipe that more is fit for the micro-pump milk usefulness, avoided reforming transform by oneself and just use with patient not passing through strict disinfection, reduce the chance of infecting and saved nurse's work.

1. a pipeline; 2. an injector; 3. a flow speed device; 4. a sharp mouth device; 41. a sharp tube; 42. a sleeve; 43. an inner tube; 44. an outer edge; 45. the inner groove wall.

Detailed Description

In order to further understand the structure, characteristics and other objects of the present invention, the following detailed description is given with reference to the accompanying preferred embodiments, which are only used to illustrate the technical solution of the present invention and are not intended to limit the present invention.

A disposable pump milk extension tube combines with a figure 1 and a figure 2, and comprises a pipeline 1, an injector 2, a flow rate device 3 and a sharp mouth device 4, wherein the pipeline 1 is a hose made of medical rubber, the injector 2 with milk is inserted into one end of the pipeline 1, the sharp mouth device 4 is inserted into the other end of the pipeline 1, the flow rate device 3 is sleeved outside the middle part of the pipeline 1, and the flow rate device 3 is a conventional infusion tube flow rate device, so that the flow rate of the pump milk is controlled.

Referring to fig. 1 and 2, the sharp mouth device 4 comprises a sharp tube 41, a sleeve 42 and an inner tube 43, one end of the sharp tube 41 is triangular, the sharp tube 41 is inserted into the nasal jejunum tube, the sharp tube 41 is fixedly connected to one side of the sleeve 42, and the outer diameter of the sharp tube 1 can be different according to the inner diameter of the nasal jejunum tube; the inner pipe 43 is fixedly connected in the sleeve 42, the inner pipe 43 is inserted in the pipeline 1, the sleeve 42 is sleeved outside the pipeline 1, and the distance between the sleeve 42 and the inner pipe 43 is smaller than the wall thickness of the pipeline 1, so that the pipeline 1 can be in interference fit with the sharp-mouth device 4 to realize tight fixation; with sharp mouth ware 4 and pipeline 1 separation, need not to make the nurse cut pipeline 1 again, avoid causing the pollution, the accessible installs different sharp mouth ware 4 additional simultaneously to the different nose jejunum pipes of adaptation.

Referring to fig. 1 and 2, the outer port of the inner tube 43 is a tip nozzle, and the length of the inner tube 43 is smaller than that of the sleeve 42, so that the sharp-mouth device 4 can be inserted into the pipeline 1; the outer edge 44 of the annular sleeve 42 is fixedly connected with the outer diameter of the outer edge 44 which is larger than the outer diameter of the sleeve 42, so that the medical staff can take the sharp mouth device 4 and insert the sharp mouth device into the pipeline 1 more conveniently; the inner side of the sharp tube 41 is provided with an inner groove wall 45, and the inner groove wall 45 is connected with the inner wall of the inner tube 43, so that the sharp tube 41 can smoothly transit with the inner wall of the inner tube 43, and the phenomenon that the flowing of milk is influenced by bubbles when the milk flows due to the interval of the transition ends is avoided.
