Description

Improved stomach tube fixing device

Technical Field

The utility model belongs to the field of medical equipment, in particular to a fixing device for indwelling stomach tubes of patients in intensive care units of hospitals.

Background

In an intensive care unit of a hospital, a stomach tube needs to be indwelling for a critical patient who cannot take food through the mouth and perform gastrointestinal decompression, so that the indwelling stomach tube is a common nursing operation in the intensive care unit. According to the state of an illness needs of patients, the time of indwelling stomach tubes is different, patients are prone to discomfort, the diameter of the stomach tube is thick, the exposed part is long, most of existing fixing methods use adhesive tapes to fix the stomach tube on two sides of a nasal wing and a cheek part, the adhesive tapes are prone to being reduced in adhesion when the skin of the patients produces oil, the stomach tube is prone to falling off, accidental tube drawing rates are increased due to the reasons, according to statistics, the occurrence rate of accidental tube drawing due to the fact that the stomach tube is not fixed is 9.8% -45.2%, stimulation and damage can be caused to nasal cavities, esophagus and gastric mucosa of the patients by repeatedly inserting the stomach tube, and workload of nursing staff is increased.

Therefore, it is necessary to find an auxiliary device which can conveniently fix the gastric tube, and simultaneously can make the patient feel comfortable and reduce the tube drawing rate.

SUMMERY OF THE UTILITY MODEL

Solves the technical problem

The fixing device solves the common problems that the serious patients are uncomfortable and easy to fall off in the fixing mode of the existing indwelling stomach tube.

Adopts the technical proposal

The utility model provides a modified stomach tube fixing device, comprises fixed cover, support gas post, intake pipe, fixed cover is the little loudspeaker appearance structure of cavity, the big near-end of distal end, and the centre is for supplying the stomach tube freely male poroid passageway, the periphery evenly distributed of fixed cover has two sets of support gas posts, the gas post is the big near-end of distal end little after aerifing, and the quantity of every group gas post has threely, all have an gasbag on every gas post, the three gasbag of every group gas post all links to each other through intake pipe and a corresponding valve group that admits air, through the valve group that admits air can be with gas injection gasbag, fixed cover is fixed connection with the gasbag.

Furthermore, the fixed connection between the fixed sleeve and the air bag is glued.

Advantageous effects

Because use the gasbag to aerify the back and to the fixed stomach tube of side pressure that the alar produced of nose, area of contact is big to pressure is little, and patient feels comfortable, and is fixed firm, moreover the utility model discloses can also work with two sets of gas columns in turn, changed with the contact position of alar nose, the messenger patient that can be better produces the comfort, the perfect fixed problem of current stomach tube of having solved.

Detailed Description

As shown in fig. 1, 2, 3, 4 and 5, 1 is a support air column a, 2 is a support air column B, 3 is a fixing sleeve, 4 is an air inlet valve group a, 5 is an air inlet valve group B, 6 is an air inlet pipe a, 7 is an air inlet pipe B, and 8 is a gastric tube.

The fixing sleeve 3 is a hollow horn-shaped structure with a large far end far away from the nasal cavity and a small near end close to the nasal cavity, the middle part of the fixing sleeve is a hole-shaped channel for freely inserting the stomach tube 8, the hole-shaped channel is a regular cylinder, the diameter of the hole-shaped channel is equal to that of the stomach tube, and the stomach tube can be freely inserted into or pulled out of the hole-shaped channel. At ordinary times, 6 air bags are in an airless state. The periphery of fixed cover 3 evenly distributed has two sets of support gas columns A and B, the gas column is after aerifing to be far away from the big three-dimensional shape of the distal end of nose greatly and the near-end little that is close to the nose, and the quantity of every group gas column has three, all have an inflatable gasbag on every gas column, and three gasbags of every group gas column all link to each other with a corresponding inlet valve group through the intake pipe, through the inlet valve group can be with gas injection gasbag, fixed cover is fixed connection through gluing with the gasbag when producing. The air bag is made of high-quality silica gel material, and the fixing sleeve is made of medical high polymer material with certain hardness.

The use method is explained by combining the structure of the device of the utility model as follows:

when the gasbag that supports gas column 1 or 2 all is airless state, hold between the fingers gently with the hand will the utility model discloses a nostril is put into with the device to the distal end of device, then paints suitable emollient such as paraffin oil with stomach tube 8, inserts poroid passageway, inserts suitable degree of depth with the stomach tube according to the scale. Use the syringe to pass through 4 intake valves A, inject 1 support air column A with the air through 6 intake pipe A, because the gasbag that supports air column A also is the structure that the distal end is big, the near-end is little, and the pressure to the lateral wall nose wing through the three gasbag that is full of gas firmly will the utility model discloses a fixing device fixes in the nose wing, because the gasbag adopts gas filled structure, therefore the area of contact of gasbag and nose wing is enough big, and the physics principle tells us under the condition that pressure is a fixed value, and area of contact is big more, and pressure just is little to the human sensation is more comfortable. The air in the gasbag also produces certain pressure to the outer wall of 3 fixed cover empty form passageways, can increase the outer wall of 3 fixed cover inside walls and act on the pressure of 8 stomach tubes to make the stomach tube be difficult to remove, see figure 2.

Similarly, also can insert suitable degree of depth at the stomach tube after, use the syringe to pass through 5 valves B that admit air, inject 2 support gas column B with the air through 7 intake pipe B, because the gasbag that supports gas column B also is the big, the little structure of near-end of distal end, through being full of the pressure of the three gasbag air-to-side wall alar firmly will the utility model discloses a fixing device fixes in the alar. Meanwhile, air in the air bag also generates certain pressure on the outer side wall of the 3-way hollow channel of the fixing sleeve, and the pressure of the outer wall of the inner side wall of the 3-way hollow channel acting on the 8 stomach tubes can be increased, so that the stomach tubes are not easy to move, and the stomach tube is shown in figure 3.

When the nasal cavity air bag is used at ordinary times, in order to not press the nasal wings for a long time, the air bags of the group A and the group B can be inflated and deflated alternately at intervals, so that a patient feels more comfortable.

The utility model discloses a modified stomach tube fixing device, simple structure, it is with low costs, processing is easy, can make into disposable aseptic product, directly takes out from aseptic package during the use, can use, is worth wideling popularize in clinic.
