Description

Novel exchange catheter, intestinal obstruction catheter kit and using method thereof

Technical Field

The invention discloses a novel exchange catheter, a catheter kit for intestinal obstruction and a using method thereof, and belongs to the technical field of medical equipment.

Background

Intestinal contents caused by any reason can not normally run and smoothly pass through the intestinal tract, which is called intestinal obstruction, and is a common surgical acute abdomen disease. It is manifested as abdominal pain, abdominal distention, vomiting, defecation and cessation of ventilation. Ileus catheters have now become indispensable for the active improvement and resolution of ileus with conservative therapy, without surgical treatment for adhesive ileus.

There are two types of ileus catheters clinically: nasal type and anal type; the placement of the ileus catheter usually adopts two methods of direct placement under an X-ray and auxiliary placement under a digestive endoscope, but certain failure rate exists, particularly about 50% of patients are intubated under the X-ray, the time consumption is too long in two links of the catheter entering the stomach body through the fundus and entering the duodenum through the antrum of the stomach, and some patients cannot be successfully placed.

The nasal ileus catheter is generally used by a nasal ileus catheter kit formed by matching a catheter with a guide wire, the kit is put into a nasal cavity when in use, but the combined outer diameter of the catheter and the guide wire is large, so that the putting is difficult and even fails, the patient can be suffered from considerable pain when the kit is directly put into the nasal ileus catheter kit, certain psychological pressure and burden are caused to a treatment putting process of medical workers, and the difficulty of the treatment process is increased; in addition, the front end of the guide wire has no developing function, so that the specific position of the end part of the guide wire is difficult to determine in the operation process and can be judged only according to the experience of medical workers.

Disclosure of Invention

Technical problem to be solved

The invention aims to solve the technical problems that the existing transnasal ileus catheter is difficult to put in the putting process, the putting process causes discomfort and even pain to patients, the putting process is long in time consumption, and meanwhile, the front end of a guide wire used in cooperation with the catheter has no developing function, so that medical workers cannot well judge the specific position reached by the guide wire.

(II) technical scheme

In order to solve the technical problems, the invention provides a novel exchange catheter, an ileus catheter kit and a using method thereof.

Furthermore, the use method of the novel exchange catheter and ileus catheter kit comprises the following steps:

the method comprises the following steps: inserting a second guide wire into the monoxius catheter, and then enabling the monoxius catheter and the second guide wire to enter the gastric cavity through the nasal cavity, the lower section of the alimentary tract and the cardia; shooting a projector to observe the intestinal mucosa, distinguishing the front direction, and finally entering the intestinal tract;

step two: taking out the second guide wire, keeping the single-bend catheter, inserting the exchange guide wire along the single-bend catheter, and further deepening the exchange guide wire in the intestinal tract;

step three: withdrawing the single-bend catheter, inserting the novel exchange catheter along the exchange guide wire, and developing the catheter to a desired position through the catheter;

step four: removing the exchange guide wire and inserting the first guide wire along the novel exchange catheter;

step five: taking out the novel exchange catheter, and inserting the intestinal obstruction catheter along the first guide wire;

step six: the first guidewire is removed.

More specifically, the above-mentioned first end head, front sub-tube, splicing sleeve, catheter body and single-bend catheter are all made of silica gel.

(III) advantageous effects

The technical scheme of the invention has the following advantages:

1. the novel exchange catheter adopts a structure that the silica gel catheter body is combined with the front catheter, so that materials are easy to draw, the production and manufacturing difficulty is not high, the comfort is good, and the novel exchange catheter is simple and practical.

2. The ileus catheter kit is placed into an ileus catheter by adopting a method of multiple replacement, seems to be complicated in process, and actually decomposes a complex operation into simple small operations which can be smoothly completed by a plurality of ordinary interventional doctors; and the novel exchange catheter, the intestinal obstruction catheter kit and the operation method have stronger adaptability to different internal structures of different bodies of different patients, ensure 100 percent of success rate of catheterization, obviously shorten the operation time (from about 30 minutes to within 10 minutes on average), and greatly reduce the X-ray acceptance of doctors and patients (only requiring 2-3min of fluoroscopy time).

3. The common catheter can not provide an inner cavity for exchanging the guide wire of 0.049 ', so that the novel exchange catheter is invented, the novel exchange catheter meets the requirement, is soft, has the lowest discomfort of a patient, can accurately hold the position reached by the end part of the novel exchange catheter due to the front substructure arranged at the front end, and is convenient for the accurate placement of the guide wire of 0.049'.

4. In the operation process, at first use cooperation such as less thin single-bending pipe, second seal wire, exchange seal wire, cross bend and stenosis, final gradual replacement is for ileus pipe for have better trafficability characteristic when placing ileus pipe, make the patient have a process of constantly adapting to whole process, avoid directly putting into difficulty, patient's misery, medical staff psychological pressure big scheduling problem with ileus pipe and seal wire.
