Description

Stomach tube replacement device without pulling out repeated insertion

Technical Field

The utility model relates to the technical field of medical supplies, concretely relates to need not to pull out device is changed to repeated male stomach tube.

Background

Patients suffering from chronic neurological disease, advanced tumors, respiratory failure, coma or vegetative states need to have a long-term indwelling gastric tube, which is given enteral nutritional support therapy to meet the energy needs of the patient and maintain life. For the people who keep the stomach tube for a long time, the stomach tube needs to be replaced regularly (generally, the stomach tube needs to be replaced once in 1-2 months), the original stomach tube needs to be pulled out, and a new stomach tube needs to be inserted again.

The gastric tube replacement method has the following disadvantages: (1) repeated insertions increase patient pain; (2) increasing clinical risk (stomach tube mistaken entering trachea, oral epiglottis secretion mistaken inhalation into airway, increasing infection chance, stimulating vagus nerve to cause bradycardia even sudden cardiac arrest, dyspnea even oxygen saturation reduction, etc.); (3) there is a certain failure rate.

Based on the defects of the existing gastric tube replacement mode, medical staff in the field urgently need a gastric tube replacement mode which can reduce pain, avoid clinical risks and ensure 100 percent success rate in the operation process.

Detailed Description

The features of the present invention and other related features are described in further detail below by way of example with reference to the accompanying drawings, for the understanding of those skilled in the art:

referring to fig. 1-5, the labels 1-7 in the figures are: the novel stomach tube comprises a steel wire track 1, a steel wire core 2, an aseptic suture 3, a new stomach tube 4, an original stomach tube 5, surgical scissors 6 and a nasal cavity 7.

Example (b): as shown in fig. 1-5, the present embodiment specifically relates to a gastric tube replacing device without pulling out and repeatedly inserting, the main body of the gastric tube replacing device comprises a steel wire track 1, in a preparation operation state, the front part of the steel wire track 1 is inserted into an original gastric tube 5, and the rear part of the steel wire track 1 is sleeved with a new gastric tube 4.

As shown in fig. 1 and 2, the steel wire track 1 in this embodiment is specifically formed by connecting two steel wire cores 2, wherein one steel wire core 2 is a guide steel wire core of an original stomach tube 5, and the other steel wire core 2 is a guide steel wire core of a new stomach tube 4; the length of each steel wire core 2 is 110cm, so that the total length of the steel wire track 1 is 220 cm; wherein, the preceding tip of steel wire core 2 is smooth globular, the end portion has spacing stopper, is the injury that smooth globular preceding tip can avoid steel wire core 2 to the esophagus, when connecting two steel wire cores 2, at first cuts out the spacing stopper of 2 end portions of steel wire core, later aligns the end portion of two steel wire cores 2 and ligates fixed connection through aseptic suture 3 to form the steel wire track 1 who is long in new stomach tube 4 and former stomach tube 5.

As shown in fig. 3-5, the length of a general stomach tube is 120cm, in this embodiment, the length of a new stomach tube 4 is 120cm, while the length of an original stomach tube 5 is cut to about 60cm in a preparation operation state, the front part of a steel wire track 1 is inserted into the original stomach tube 5, the rear part of the steel wire track 1 is sleeved with the new stomach tube 4, in order to reduce friction force, paraffin oil is coated on the steel wire track 1 for lubrication, and paraffin oil is coated on the inner wall of the new stomach tube 4 and the inner wall of the original stomach tube 5 for lubrication. It should be noted that the gastric tube replacing device further comprises a cutting device, in this embodiment, a pair of conventional surgical scissors 6 is adopted, and the original gastric tube 5 can be cut and withdrawn by the surgical scissors 6.

As shown in fig. 1 to 5, the operation method of the gastric tube replacement device without removing the repeatedly inserted gastric tube specifically comprises the following steps:

(1) cutting off the limiting plugs at the tail end parts of two steel wire cores 2 with the length of 110cm, and then ligating, fixing and connecting the tail end parts of the two steel wire cores 2 by using an aseptic suture 3 to form a whole steel wire track 1, wherein the length of the steel wire track 1 is 220 cm; paraffin oil is coated on the steel wire track 1 so that the steel wire track can lubricate a new stomach tube 4 and an original stomach tube 5 which are involved subsequently, and friction force in the insertion process is reduced;

(2) observing the feeding depth of the original stomach tube 5, wherein the feeding depth of the front part of the original stomach tube 5 from the nasal cavity 7 to the inside is about 60 cm; sleeving a new stomach tube 4 at the rear part of the steel wire track 1, wherein the reserved length of the front part of the steel wire track 1 is smaller than the feeding depth of the original stomach tube 5, and the front part of the steel wire track 1 can cross the epiglottis to reach the middle and lower esophagus section optimally after being inserted into the original stomach tube 5, so that the length of the front part of the steel wire track 1 is reserved by about 50cm under the condition that the feeding depth of the original stomach tube 5 is 60 cm;

(3) then, the reserved part (50 cm) at the front part of the steel wire track 1 is sent into the original stomach tube 5, and after the sending length reaches the specified 50cm, a helper beside fixes the steel wire track 1 to prevent slippage; then, cutting the original stomach tube 5 along the rear end part of the original stomach tube by using the surgical scissors 6 while pulling the original stomach tube 5 away until the original stomach tube 5 is completely pulled away and withdrawn, and at the moment, leaving the front part of the steel wire track 1 from the nasal cavity to the middle-lower section of the esophagus;

(4) after the original stomach tube 5 is drawn away, a new stomach tube 4 is fed into the nasal cavity 7 along the steel wire track 1 by 60cm, so that the new stomach tube 4 can cross the epiglottis and the middle and lower esophagus to reach the stomach cavity under the guidance of the steel wire track 1, and at the moment, the new stomach tube 4 is larger than the feeding depth of the steel wire track 1;

(5) after the feeding of the new gastric tube 4 is completed, the steel wire track 1 is withdrawn from the new gastric tube 4, and the new gastric tube 4 is fixed on the skin at the nasal tip through medical adhesive plaster;

(6) a small amount of air or normal saline is injected into the new stomach tube 4, the upper abdomen is auscultated, and the air blowing water sound can be heard, so that the front end part of the new stomach tube 4 is confirmed to be positioned in the stomach cavity.

The advantages of this embodiment are: (1) the structure is simple, the steel wire track supporting principle is applied, the steel wire track for guiding is sent into the original stomach tube, the original stomach tube exits along the steel wire track, and then the new stomach tube is sent along the steel wire track, so that the operation process is painless, the success rate is 100 percent, and the clinical risk is avoided; (2) the existing stomach tube original steel wire core is fully utilized for ligation and lengthening, the supporting force is good, and the stomach tube is not easy to slide; (3) the steel wire track is fed into the stomach tube, and the front end part of the steel wire track is positioned at the middle lower section of the esophagus (the key point is to cross the epiglottis), so that the stomach tube is not too deep and can prop against or stimulate the stomach mucosa to be damaged, and the discomfort of a patient is caused.
