Abstract

A kind of screw type jejunal nutrient canal, comprise body (1), fill with liquid mouth (2) and head (3), filling with liquid mouth is connected with the rear end of body, head is fixed on the front end of body, the forward end seal of head, on the sidewall of head, have liquid outlet (4), on the wall of body (1), approaching head place has first handle hole (5), on the wall of body (1), from head (3) 90～100cm places, has second handle hole (6).During the screw type jejunal nutrition cannula of this structure, can first utilize the stomach tube being retained in patient body that guide wire is inserted to gastric, rely on again two handle holes on screw type jejunal nutrient canal that screw type jejunal nutrient canal is enclosed within on guide wire, screw type jejunal nutrient canal inserts in patient body along guide wire, thereby guarantees intubate success.

Description

Screw type jejunal nutrient canal

Technical field

This utility model relates to a kind of medical apparatus and instruments, a kind of structure of screw type jejunal nutrient canal.

Background technology

Screw type jejunal nutrient canal comprises a soft body, fills with liquid mouth and head, and the forward end seal of head, has liquid outlet on the sidewall of head.Screw type jejunal nutrient canal is for stomach tube nasal feeding difficulty and patient that the function of small intestinal also exists, and the anterior spirality of screw type jejunal nutrient canal, can enter through the wriggling of gastrointestinal small intestinal, and nutritional solution is directly sent into small intestinal.The material of screw type jejunal nutrient canal body is softer, during insertion, need in body, insert guide wire helps, even if but used guide wire, the front portion of screw type jejunal nutrient canal is embayment hook-type still, because the pharyngeal shape of human body is more complicated, screw type jejunal nutrient canal easily enters pharyngeal other positions and is difficult for entering esophagus, and particularly the patient of stupor, easily causes intubation defeat.

Summary of the invention

This utility model is intended to propose a kind of screw type jejunal nutrient canal that improves structure, is applied to keep somewhere the patient of stomach tube, can improve the success rate of intubate.

This screw type jejunal nutrient canal comprises body, fills with liquid mouth and head, filling with liquid mouth is connected with the rear end of body, head is fixed on the front end of body, the forward end seal of head, on the sidewall of head, there is liquid outlet, on the wall of body, approaching head place has first handle hole, on the wall of body, from head 90～100cm place, has second handle hole.

During the screw type jejunal nutrition cannula of this structure, can first utilize the stomach tube being retained in patient body that guide wire is inserted to gastric, rely on again two handle holes on screw type jejunal nutrient canal that screw type jejunal nutrient canal is enclosed within on guide wire, make screw type jejunal nutrient canal insert in patient body along guide wire, thereby guarantee intubate success.

Accompanying drawing explanation

Accompanying drawing is the structural representation of screw type jejunal nutrient canal of the present utility model.

The specific embodiment

As shown in the figure, this screw type jejunal nutrient canal comprises body 1, fills with liquid mouth 2 and head 3, fills with liquid mouth and is connected with the rear end of body, and head is fixed on the front end of body, and the forward end seal of head has liquid outlet 4 on the sidewall of head.On the wall of body 1, approaching head place has first handle hole 5, on the wall of body, from head 90～100cm place, has second handle hole 6.

The screw type jejunal nutrient canal of this structure, concrete operation step during intubate is as follows:

1, at patient's wing of nose position, cut off stomach tube;

2, take off the seal wire cap of guide wire tail end, the front end of guide wire is inserted in the stomach tube in patient body, until that guide wire enters the length of stomach tube in Length Ratio body in body is slightly short, the front end of guide wire enters gastric, and now the length of guide wire in patient body is about 50cm;

3, along guide wire, remaining stomach tube is extracted in body, and removed from the tail end of guide wire;

4, the tail end of guide wire is inserted in first handle hole 5 of screw type jejunal nutrient canal, screw type jejunal nutrient canal cover is incorporated on guide wire, until when the tail end of guide wire arrives second handle hole 6 place on screw type jejunal nutrient canal, in second handle hole 6 of the tail end that makes guide wire from screw type jejunal nutrient canal, stretch out;

5, continue screw type jejunal nutrient canal to insert in patient body along guide wire, until enough length (90cm left and right), then guide wire is extracted in screw type jejunal nutrient canal;

6, with adhesive plaster, second handle hole on screw type jejunal nutrient canal 6 sealed, make second handle hole ne-leakage after sealing, screw type jejunal nutrient canal is fixed, operation has accused.

Because the front end of stomach tube is straight type, and there is certain hardness, more easily insert, the stomach tube that utilization is retained in patient body inserts gastric by guide wire, rely on again two handle holes on screw type jejunal nutrient canal of the present utility model that screw type jejunal nutrient canal is enclosed within on guide wire, along guide wire, insert in patient body, thereby guarantee intubate success, insert success rate and can reach 100%, and can reduce the complication of putting in pipe process.

Screw type jejunal nutrition length of tube is generally 145cm, diameter 3.3mm, and guidewire length is also 145cm, diameter 1mm.The diameter of first handle hole 5 and second handle hole 6 can be 1.2～1.5mm.The length of screw type jejunal nutrition tube head is about 12mm, and first handle hole 5 can be 5mm left and right apart with head.

Claims

1. a screw type jejunal nutrient canal, comprise body (1), fill with liquid mouth (2) and head (3), filling with liquid mouth is connected with the rear end of body, head is fixed on the front end of body, the forward end seal of head, has liquid outlet (4) on the sidewall of head, it is characterized in that, on the wall of described body (1), approaching head place has first handle hole (5), on the wall of body (1), from head (3) 90～100cm places, has second handle hole (6).
