Description

A kind of nose bile drainage tube with a scale

Technical field

The utility model belongs to the field of medical instrument technology, more particularly to a kind of nose bile drainage tube with a scale.

Background technique

Nasobiliary drainage (ENBD) is set up on the basis of endoscopic retrograde cholangiopancreatography (ERCP) A kind of method through scope external biliary drainage.ENBD is fast etc. excellent because of easy to operate, the less, few intercurrent disease of pain, glucose recovery Point, is widely used in clinic.Operator is inserted into bile duct under scope through duodenofiberscope using an elongated plastic tube, The other end through duodenum, stomach, oesophagus, pharynx etc. outside the lead body of nostril, to set up the external drainage approach of bile.According to The difference of conditions of patients, most of nose bile ducts be required to indwelling in patient body for a period of time, after patient symptom improvement after again into Row takes out.It is found in clinical care, the patient for placing nose bile drainage tube is because of the movement of position, different constitution difference and drainage The many factors such as the pipe stimulation pharyngeal to patient are often occurred drainage tube and are slipped out of patient bile duct or production the phenomenon that dystopy It is raw, and whether nose bile drainage tube on the market can not observe drainage tube and deviate from or dystopy at present, be unfavorable for clinical care.Nose gallbladder draws Often by medical worker's manual markings and fixed drainage tube after flow tube placement, the mode of this manual markings is very troublesome, The workload of medical personnel is increased, and does not have stability, often patient has shown undesirable condition Shi Zaihang X-ray The methods of check related causes, not only increase the pain of patient, also increase the workload of doctor and nurse.

Meanwhile during current nasobiliary drainage, according to the different illness situation of patient, doctor, which can take, to place Nose bile drainage tube after a period of time cuts the therapeutic modality at inner drainage tube from duodenum；But at duodenum Space is narrow, and doctor is relatively difficult at the position of judgement shearing drainage tube, if too short be easy to cause of clipped position is drawn Flow tube is slipped in biliary tract, damage that is too long and be easy to causeing duodenal wall mucosal tissue, so patient is caused it is unnecessary Injury.

In view of the above deficiencies, a kind of nose bile drainage tube need to be explored, medical worker is enabled clearly to judge patient's body Then the position of nose bile drainage tube carries out accurately operating in next step.

Utility model content

For this purpose, the technical problem to be solved by the utility model is to provide a kind of nose bile drainage tubes with a scale, to cure Business personnel can clearly judge the position of patient's body nose bile drainage tube.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

The nose bile drainage tube with a scale of the present embodiment, as shown in Figs. 1-3, comprising: female Luer 1, nut 2, drainage tube 3。

One end of the female Luer 1 is equipped with screw thread, and the other end is suitable for connecting with drainage bag (not shown).As this The specific implementation of embodiment, the female Luer are public female Luer, suitable for the female Luer connector on the drainage bag Cooperation.For realizing the purpose of this utility model, the material of the female Luer 1 is not unique, provides in the present embodiment A kind of specific design method, the female Luer 1 are made of polycarbonate.It alternative implementation as the present embodiment, The female Luer 1 also can be used ABS plastic and be made.Wherein, ABS plastic refers to acrylonitrile-butadiene-styrene (ABS) plastics.

The nut 2 cooperates with the female Luer 1；For the internal and external threads for ensureing the female Luer 1 and the nut 2 It is fitted close, prevents the two from mutually sliding, sealing ring is equipped between the female Luer 1 and the nut 2.

The pipe shaft of the drainage tube 3 is equipped with scale 32；The drainage tube 3 includes first end and second end.It needs to illustrate , the scale 32 on the drainage tube 3 can be respectively provided on entire pipe shaft, can also the drainage tube 3 first end, The scale 32 of two ends both ends setting certain length；The scale 32 is arranged on the pipe shaft of the drainage tube 3 by printing.

The first end is equipped with conduction hole 31, and the second end is connect by the nut 2 with the female Luer 1, fits The drainage bag is flowed by the drainage tube 3 in the liquid for drawing the conduction hole 31.Specific reality as the present embodiment Existing mode, the drainage tube 3 are made up of PE modified plastics of extrusion molding.It is described PE modified in the present embodiment Plastics are that polyethylene adds the modified plastics that developer obtains, and the drainage tube 3 made of the material has roentgenopaque spy Property, the drainage tube 3 can be positioned under X-ray.

To smoothly enter human biliary duct position convenient for the drainage tube 3, the first end of the drainage tube 3 is in coniform. It alternative implementation as the present embodiment, the first end of the drainage tube 3 can be in a circular table shape.

For convenient for more swimmingly draining to bile, the conduction hole 31 of the drainage tube 3 is multiple, and along the drainage It is spirally distributed on the tube wall of the first end of pipe 3.Helical form refers in the circumferential direction of the drainage tube 3, the conduction hole 31 It is placed equidistant with, the helically curve of the line between the adjacent conduction hole 31.

For convenient for being aligned to the drainage tube 3, as shown in figure 4, the nose bile drainage tube with a scale further includes rectifying The caliber of straight tube 4, the aligning pipe 4 is greater than the caliber of the drainage tube 3, suitable for being sheathed on the outside of the drainage tube 3.This reality It applies in example, the aligning pipe 4 is vinyl tube.

The course of work of nose bile drainage tube with a scale described in the present embodiment is as follows:

Operator first penetrates the aligning pipe 4 in the drainage tube 3, and the aligning pipe 4 of being formed is in the drainage The drainage tube 3 is aligned in position on pipe 3；

The first end of the drainage tube 3 after aligning is led into human body by seal wire, reaches designated position, then will lead Silk is withdrawn from, and the release of the drainage tube 3 is completed；

The female Luer 1 and the nut 2 are tightened, second end and the institute of the drainage tube 3 outside human body are made The connection of female Luer 1 is stated, then the drainage bag is connect with the female Luer 1；

After the drainage tube 3 is fixed out of the human body, record the drainage tube 3 and expose scale at nostril, convenient for pair Drainage tube carries out the monitoring in later period in the intracorporal position of people.

Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or It changes among the protection scope created still in the utility model.
