Description

Naso-intestinal tube guiding assembly

Technical Field

The utility model belongs to the field of medical equipment, a nose intestines tube guide assembly specifically says so.

Background

ICU critically ill patients use stomach tubes to provide nutrients, while some gastroparesis patients require the aid of naso-intestinal tubes because the peristalsis of the stomach disappears and food is retained in the stomach. However, since gastric motility disappears, it is difficult for a nurse to insert the nasointestinal tube into the intestinal tract, and even with the aid of a guide wire, the nasointestinal tube often wanders in the stomach, and the gastrointestinal tract cannot be accessed through the pylorus.

Therefore, the invention patent of China with the patent number CN109011105A discloses a laparoscopic nasointestinal tube implanting device in 2018, 12 and 18, which comprises a nasointestinal tube, a disposable sterile sleeve, a guide core and a magnetic guider. Wherein the guide core is composed of a guide core head, a guide wire and a power supply device. The guide core head is provided with an LED light source, and the position of the tip of the nasointestinal tube can be determined under the laparoscope after the LED light source is turned on. The core guiding head is made of nickel-iron alloy, and can lead the nasointestinal tube to enter the intestinal tract through pylorus by magnetic force.

In the actual use process, the attractive force between the magnetic guider and the core guiding head is influenced by various factors, particularly the distance, so that the effect is different for patients with different body types, and the overall guiding effect is poor.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a nose intestines tube guide assembly, guide nose intestines tube smoothly to get into the intestinal through the pylorus portion, overcome the defect among the prior art.

The utility model adopts the following technical scheme:

the utility model provides a nose intestines tube guide assembly, is including acting on the seal wire of nose intestines tube and guide the seal wire drives the directional guide piece that removes of nose intestines tube, the front end of seal wire is provided with the magnetic force spare that has magnetic force, the guide piece is for magnet or the metal article with magnetic force spare inter attraction, magnetic force spare can dismantle connect in the seal wire front end.

In the technical scheme, the magnetic part on the guide wire has magnetic force, the external guide part can be a magnet or any metal object attracted with the magnetic part, so that a nursing worker can use any metal object on hand to conduct guiding operation during operation, and particularly, the guide wire is more convenient to use under the condition that the magnet is lost.

Among the above-mentioned technical scheme, magnetic force spare can dismantle the setting, can change the magnetic force spare that has without magnetic force according to the different fat degree of different sizes to under the condition that the distance changes between magnetic force spare and guiding piece, keep suitable appeal, avoid leading to the too big and slow that advances between nasointestinal tube and the stomach wall because of the appeal is too big, perhaps lead to playing high-efficient guide effect because of the appeal undersize.

Above-mentioned technical scheme, along the physiology structure direction between human stomach and the intestines pipe, remove the guide, the guide nose intestines pipe gets into the intestinal through pylorus portion.

Preferably, the front end of the guide wire is provided with a guide wire hook and a workpiece placing box detachably connected with the guide wire hook, and the magnetic part is placed in the workpiece placing box.

Preferably, the piece placing box is divided into two parts, one side of each part is hinged, the other side of each part is connected in a buckling mode, and a hook hole matched with the wire guide hook is formed in the piece placing box.

Preferably, the guide wire hook is provided with a barb.

Preferably, the workpiece placing box is a spherical workpiece placing box.

Preferably, the magnetic member comprises a plurality of magnetic beads.

Preferably, the guide is a U-shaped magnet.

Through implementing above-mentioned technical scheme, the utility model has the advantages of as follows: 1. the nasal and intestinal canal is guided to smoothly enter the intestinal canal through the pylorus by the attraction between the magnetic force piece and the guiding piece; 2. the external guide piece can be a magnet or any metal object attracted with the magnetic piece, so that the use is convenient; 3. the magnetic member without magnetic force is replaced according to patients with different body types and different obesity degrees, and the guiding is efficient.

Detailed Description

The present invention will be described in further detail with reference to the following specific examples.

Example 1:

a nasointestinal tube guiding assembly is matched with an existing nasointestinal tube for use, and comprises a guide wire 10 acting on the nasointestinal tube and a guide piece 20 for guiding the guide wire 10 to drive the nasointestinal tube to move directionally, as shown in figure 1. The distal end of the guide wire 10 is provided with a magnetic member 30 having a magnetic force, and a permanent magnet is used. The guide 20 acts outside the body and is a magnet that attracts the magnetic member 30, preferably in the present embodiment, the magnet is U-shaped. The guide 20 may be a metal object that can be easily taken by a caregiver as long as it can attract the magnetic member 30. Magnetic force piece can dismantle connect in the seal wire front end, specific structure, this embodiment is as follows: the front end of the guide wire is provided with an annular ring 101, the upper edge and the lower edge of the annular ring 101 are provided with edges, a cavity for placing the magnetic member 30 is formed in the middle, as shown in figure 2, the annular ring 101 is provided with a longitudinal crack, the strength is increased, the magnetic member can be detached from the annular ring 101, and the magnetic member with larger or smaller magnetic force can be replaced.

Example 2:

a nasointestinal tube guiding assembly is matched with an existing nasointestinal tube for use, as shown in the attached figure 2, and is different from the embodiment 1 in that:

the seal wire 10 front end is provided with seal wire hook and spherical putting a box 40, as shown in figure 3, puts a box and divide into one side articulated, two parts that opposite side buckle formula is connected, put be provided with on the box with seal wire hook complex hook hole, be provided with the barb on the seal wire hook, prevent to put a box and drop. The magnetic piece is arranged in the piece placing box. The magnetic member comprises a plurality of magnetic beads, and the number of particles in the workpiece placing box is increased or decreased according to needs so as to increase or decrease the attraction force between the magnetic member and the guide member.
