Description

Hydrophilic superslide gastric tube

Technical field

The utility model is related to a kind of conduit medicine equipment applied to enteral nutrition, more particularly to a kind of hydrophilic super profit stomach Intestinal tube.

Background technology

Enteral nutrition (enteralnutrition, EN) is to provide the nutriment and other are each that metabolism needs through intestines and stomach Plant the nutritional support mode of nutrient.The approach of enteral nutrition has oral and inputs two kinds through conduit, wherein being inputted through conduit many Using nose catheter, nose duodenal tube, Nasal cavity intestinal tube and stomach jejunum stoma pipe.Enteral nutrition has, energy more balanced than parenteral nutrition Improve gastrointestinal function, improve every physiological function, operate the advantage such as relatively easy, therefore receive clinical attention more and more And be widely adopted.Gastric tube is to be inserted into enteral by stomach by nasal cavity or oral intubation to carry out enteral nutrition.But, pass The gastrointestinal nutrition tube of system is due to itself material, reasons in structure, and stomach and intestine inwall intubation resistance is big, by resistance during pylorus turning just It is bigger, it is intubated under x-ray fluoroscopy, can not also guarantees to put pipe completely in place, simultaneously as difficult intubation, so doctor The raw operating time is longer, and inefficiency, patient is extremely uncomfortable.

Utility model content

The technical problems to be solved in the utility model be to provide one kind put pipe simple and fast, easily in place, improve doctor Patient's uncomfortable hydrophilic superslide gastric tube can be mitigated while operating efficiency significantly again.

The hydrophilic superslide gastric tube of the utility model, including Straight body, body one end connection dual-chamber multifunctional connect Head and female Luer, the other end form bent angle after being bent upwards, the end of the other end is provided with opening, the body it is interior PVP coatings are coated with wall, outer wall.

The hydrophilic superslide gastric tube of the utility model, wherein the bent angle is 5~90 relative to the angle of bend β of body axial direction Degree.

The hydrophilic superslide gastric tube of the utility model, wherein the inner chamber caliber of the body is 1.0~3.8mm.

The hydrophilic superslide gastric tube of the utility model, wherein the body is by appointing in polyurethane, polyvinyl chloride or silicon rubber One kind is made.

The hydrophilic superslide gastric tube of the utility model can relatively be easily passed under x-ray fluoroscopy pylorus reach enteral to Support, put pipe success rate and greatly improve and simple and quick, not only improved working doctor efficiency but also alleviated to a greater extent The discomfort of patient.

Hydrophilic superslide gastric tube of the present utility model is described further below in conjunction with the accompanying drawings.

Embodiment

As shown in Figures 1 to 5, the hydrophilic superslide gastric tube of the utility model includes Straight body 3, the connection of the left end of body 3 Dual-chamber multifunctional joint 1 and female Luer 2, the main chamber of dual-chamber multifunctional joint 1 can connect syringe or nutrition joint and be noted toward enteral Enter nutrient solution, female Luer 2 can connect syringe or other female Luers are rinsed, inject and aspirated.The right-hand member end of body 3 Head forms bent angle 6 after being bent upwards.The number of degrees of bent angle 6 are the angle of bend of 5~90 degree, the i.e. bent angle 6 relative to the axial direction of body 3 β is 5~90 degree, and the right-hand member of body 3 can relatively easily pass through pylorus turning when conveniently putting pipe.The inner chamber caliber of body 3 be 1.0~ 3.8mm, can preferably meet nutrient solution has enough flow cavities, it is to avoid body 3 is blocked.Body 3 is by polyurethane, polyvinyl chloride Or any of silicon rubber is made, therefore body 3 can develop under x-ray fluoroscopy.PVP coatings 4 are coated with the inwall of body 3. PVP is the abbreviation of polyvinylpyrrolidone (Polyvinylpyrrolidone), is that NVP polymerize The high-molecular compound of generation.Polyvinylpyrrolidone is that white has hygroscopic powder, odorless or micro- smelly, water-soluble, second Alcohol, chloroform and most organic solvents, insoluble in ether, toxicity is smaller.In use, need to only be injected by dual-chamber multifunctional joint 1 A small amount of sterilized water or physiological saline soak tens seconds, and PVP coatings 4 have the performance for being swelled superslide, effectively prevent Larger frictional resistance is produced between body 3 and seal wire 9, it is to avoid put when pipe plugs seal wire 9 afterwards in place body 3 because of above-mentioned friction Resistance and be carried over, the plug of seal wire 9 is very easy to, while the PVP coatings 4 of superslide also efficiently avoid nutriment Resulted in blockage on the adhesion inwall of body 3.Similarly, PVP coatings 4 are also coated with the outer wall of body 3, coat the hydrophily superslide coating Afterwards, it only need to soak body 3 tens seconds with sterilized water or physiological saline before being intubated, the property of superslide is swelled using PVP coatings 4 Can, substantially reduce and entirely put the frictional resistance produced between pipe process body 3 and gastrointestinal mucosa, it is ensured that intubation it is light soon It is prompt.The right-hand member end of body 3 is provided with opening 7, such design so that be difficult residue adhesion in tube wall after nutriment injection On, it efficiently avoid plugging.On above-mentioned seal wire 9 carry seal wire handle 8, can Auxiliary support intubation use.

Hydrophilic superslide gastric tube of the present utility model coats hydrophily superslide coating on the inwall and front end outer wall of body 3 PVP coatings 4, and the right-hand member of body 3 has been done into curved design, while devising the rational internal diameter cavity diameter of body 3, use process Water profit immersion body 3 is only needed, due to the excellent greasy property of PVP coatings 4, body 3 easily can put pipe under X-ray by pylorus To enteral, so as to carry out enteral nutrition.

In summary, it can be greatly reduced after hydrophilic superslide gastric tube of the present utility model, the immersion lubrication of body 3 and entirely put pipe Resistance between process middle tube body 3 and gastrointestinal mucosa so that intubation is easily quick.Meanwhile, the right-hand member of body 3 is curved design, more Pylorus is easily passed through, and after the immersion of the superslide coating of the inwall of body 3, outer wall, has greatly facilitated the plug of seal wire 9, it is ensured that put Pipe success, substantially increases working doctor efficiency, reduces doctor's labor intensity, the discomfort of patient is alleviated to a greater degree.

Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality New scope is defined, on the premise of the utility model design spirit is not departed from, and those of ordinary skill in the art are to this Various modifications and improvement that the technical scheme of utility model is made, all should fall into the protection of the utility model claims determination In the range of.
