Description

A kind of nutritive canal of ultrasound guidance

Technical field

This utility model relates to a kind of nutritive canal, particularly a kind of nutritive canal of ultrasound guidance.

Background technology

The laying method that current gastrointestinal nutrition tube is conventional has 1, place in art, 2, place under X-ray examination, this modes of emplacement cannot be implemented by straightforward manipulation on one's sick bed, and X-ray can cause additional injury to patient, 3, percutaneous gastrointestinal implements fistulation, and the method can cause larger wound to patient, the postoperative danger occurring the complication such as infection, and patient's acceptance is low and be not suitable for ascites or have the situation of upper abdominal surgery history, 4, doctor's Bedside Blind inserts to be put, insert from nose, through harmonization of the stomach duodenum, then Qu Shi ligament place is arrived, the path of process very long, and containing multiple narrow and tortuous position, the doctor that this mode needs higher experience implements, but still can cause usually being difficult to gastrointestinal nutrition tube to guide to required optimum position clinically, greatly can reduce clinical therapeutic efficacy, screw type nose bile duct or head end is often selected to have the jejunum pipe of multiple little steel ball, gastric peristalsis is relied on to make nutritive canal arrive jejunum, required time is about 8-12 hour, need repeatedly X-ray location, length consuming time, success rate is not high yet, poorer in patient's effect of enterokinesia difference, 5, through endoprosthesis, the time is short, although success rate is high, some patient is not suitable for moving, and bedside's operation needs machine to carry, and in addition, under single scope, operation needs operator experienced.

Utility model content

Utility model object: technical problem to be solved in the utility model is for the deficiencies in the prior art, provides a kind of nutritive canal of ultrasound guidance.

In order to solve the problems of the technologies described above, the utility model discloses a kind of nutritive canal of ultrasound guidance, comprise outer tube and the interior pipe being arranged on outer tube, described interior pipe two ends are provided with opening, described proximal outer tube is provided with opening, far-end closes, and described distal outer tube port outer side covers metal epidermis, described outer tube is provided with water pocket near metal epidermis place.

In this utility model, described metal material meets biocompatibility.

In this utility model, described metal material surface is arranged to knurling, is convenient to ultrasonic locating.

In this utility model, described metal material surface is arranged to pit shape, is convenient to ultrasonic locating.

In this utility model, described pit is rhombus pit.

In this utility model, described pit is semicircular recess.

In this utility model, described outer tube and interior pipe not connected.

Beneficial effect: 1, this utility model breaches the restriction that nutritive canal usually directly cannot be placed before sick bed, makes doctor rapidly and efficiently to treat patient.

2, the irradiation of this utility model by ultrasound feedback thus without the need to carrying out X-ray, improves therapeutic efficiency, it also avoid the injury of X-ray.

3, this utility model carries out nutritive canal location by ultrasound feedback, allows doctor grasp treatment process in real time, effectively improves therapeutic efficiency.

4, this utility model uses the metal material meeting biocompatibility as the main source of position feedback, effectively raises positioning precision, thus makes nutritive canal can be delivered to optimal treatment position, effectively promote therapeutic effect than single water pocket location.

Accompanying drawing explanation

To do this utility model below in conjunction with the drawings and specific embodiments and further illustrate, above-mentioned or otherwise advantage of the present utility model will become apparent.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is distal outer tube knurling metal material schematic diagram;

Fig. 3 is distal outer tube pit shape metal material schematic diagram.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is elaborated.

As Fig. 1, the utility model discloses the nutritive canal of ultrasound guidance, comprise metal epidermis 1, water pocket 2, outer tube 3 and interior pipe 4, described interior pipe 4 is arranged on the inside of outer tube 3, all there is opening at interior pipe 4 two ends, outer tube and interior pipe not connected, the part of the outer tube 3 of the nutritive canal far-end 5 of ultrasound guidance and interior pipe 4 centre closes, the part of the outer tube 3 of the nutritive canal near-end 6 of ultrasound guidance and interior pipe 4 centre is provided with opening, the outer surface of outer tube 3 far-end 5 is provided with metal epidermis 1, outer tube is provided with water pocket 2 near metal epidermis 1 place, metal epidermis 1 is for meeting the metal material of bio-diversity.

As Fig. 2 and Fig. 3, metal epidermis 1 of the present utility model can be arranged to annular knurl type and pit type, makes its surface have certain unevenness, feeds back for echo.

This utility model in use, far-end and water pocket end are inserted in patient body, proximal end, toward between interior pipe and outer tube not the part of closing any opening import required liquid, doctor is by the position of the ultrasonic locating Real-Time Monitoring nutritive canal of water pocket and metal epidermis, the use of metal epidermis uses more merely the nutritive canal of water pocket to improve ultrasonic effect, thus make placement effect reach best, meanwhile, ultrasonic locating reduces the injury that patient is subject to, allow doctor grasp treatment process in real time, improve therapeutic efficiency.

This utility model provides a kind of nutritive canal of ultrasound guidance; the method and access of this technical scheme of specific implementation is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from this utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.The all available prior art of each ingredient not clear and definite in the present embodiment is realized.
