Description

Gastrointestinal decompression device

Technical Field

The utility model relates to a medical instrument, in particular to a gastrointestinal decompression device.

Background

Gastrointestinal decompression is a method of inserting a nasogastric tube from oral cavity or nasal cavity, connecting a negative pressure generating device, and leading the gastric contents out of the body of a patient under the action of the negative pressure principle. The method can suck gas or liquid from gastrointestinal tract, reduce pressure in gastrointestinal tract, reduce gastrointestinal swelling degree, improve gastrointestinal wall blood circulation, and promote healing of stomach wound and recovery of function. However, when a general patient uses the nasogastric tube, the nasogastric tube is usually required to be treated for a period of time, and the nasogastric tube can be pulled out by medical staff after the condition of the patient is stable. However, when the nasogastric tube is inserted into the patient from the nasal cavity, the patient is usually difficult to adapt to the feeling that "foreign body" is stored in the esophagus and the throat, and particularly, in the early stage of intubation, the patient may not endure discomfort, intentionally or unintentionally pulls out the nasogastric tube by himself, which causes the whole group of medical staff to have to put down the hands to perform the work, and puts the nasogastric tube on the patient again, which not only causes the work of the medical staff to be aggravated, but also may cause the organ to be injured due to the patient pulling out the nasogastric tube by himself. Currently, to avoid this problem, it is common practice to apply tape over the patient's nasal wings for fixation. However, if the nasal mask is used for a long time, the patient may not feel comfortable and may also cause the pressure of the nasal wings to be dark and bruise. It can be seen that there is a need for improvements in current gastrointestinal decompression devices.

To maintain the following description of the embodiments of the present disclosure clear and concise, a detailed description of known functions and known components have been omitted from the present disclosure.

The embodiment of the utility model provides a gastrointestinal decompression device, including negative pressure generating device (the attached drawing is not shown) and nasogastric tube, wherein, negative pressure generating device generally can select equipment such as vacuum pump, and the structure of nasogastric tube is as shown in fig. 1 to 4, and gastrointestinal decompression device's nasogastric tube 100 contains an elasticity body 1, a first passageway 2, a second passageway 3, a third passageway 4, a fourth passageway 5.

The flexible tube 1 includes an inlet end 11, an outlet end 12, an inflation portion 13, a drainage portion 14 and a spraying portion 15. The inlet end 11 has a first opening 111, a second opening 112, a third opening 113 and a fourth opening 114. The outlet end 12 is disposed opposite the inlet end 11, and the outlet end 12 is provided with three openings 121 (only one is indicated in the drawing).

The inflatable portion 13 is disposed between the inlet end 11 and the outlet end 12, and in the present embodiment, the inflatable portion 13 is adjacent to the outlet end 12. The drainage portion 14 is disposed between the inflation portion 13 and the inlet end 11, and in the present embodiment, the drainage portion 14 is adjacent to the inflation portion 13. The spraying portion 15 is disposed between the inlet end 11 and the drainage portion 14.

The first channel 2 is disposed in the elastic tube 1 and is communicated with the first opening 111 and the opening 121, and when the opening 121 is placed in the stomach, the first channel 2 can be used to draw liquid or gas in the stomach, thereby achieving the purpose of pressure reduction.

The second channel 3 is arranged in the elastic tube body 1 and is communicated with the second opening 112 and the inflating part 13; wherein, the portion of aerifing 13 is for example the air chamber of seting up in elastic tube body 1, and the pipe wall of the portion of aerifing 13 is thinner than the pipe wall of second passageway 3, consequently when the portion of aerifing 13 is inserted to the stomach by patient's nasal cavity, can supply the user to utilize second opening 112 to aerify portion 13 and inflate to the inflation, the portion of aerifing 13 of inflation and then can block and locate in the stomach, avoid the patient to pull out stomach tube 100 of stomach intestine pressure relief device by oneself, the security in the effectual promotion use, and can reduce medical staff's burden.

The third channel 4 is disposed in the elastic tube 1 and is communicated with the third opening 113 and the drainage portion 14, and the inflated portion 13 can be clamped at the junction (cardia) of the stomach and the esophagus to draw out the liquid in the esophagus.

The fourth channel 5 is disposed in the elastic tube 1 and is connected to the fourth opening 114 and the spraying portion 15 for spraying the medicament onto the inner wall of the esophagus, so as to further clean or treat the esophagus.

The first channel 2, the second channel 3, the third channel 4 and the fourth channel 5 are not communicated with each other and are arranged in parallel.

As shown in fig. 1 and 4 to 6, the spraying portion 15 has four uniformly distributed spraying holes 151a, 151b, 151c, and 151d, and the spraying holes 151a, 151b, 151c, and 151d are all connected to the fourth channel 5, so that the spraying portion 15 can spray the esophagus in a large area, thereby improving the cleaning efficiency. In other embodiments, when the number of the spraying holes is more than two, the fourth channel 5 can also be communicated with the channel between the two spraying holes, so that the liquid injected into the fourth channel 5 can be uniformly dispersed to the two spraying holes, and the over-high spraying pressure caused by the direct communication of the spraying holes to the fourth channel is avoided.

As shown in fig. 7, the inflation portion 13 enters a stomach 300 (only a part of the stomach is shown in the figure) through an esophagus 200, when the inflation portion 13 is expanded, the user can pull the nasogastric tube 100 of the gastrointestinal decompression device outwards to make the expanded inflation portion 13 abut between the stomach 300 and the esophagus 200, and then inject the medicament into the fourth opening 114, so that the medicament flows to the spraying portion 15 through the fourth channel 5 and is sprayed to the esophagus 200 of the patient by the spraying portion 15; then, since the opening between the esophagus 200 and the stomach 300 is closed by the inflation portion 13, the medicine is accumulated in the esophagus 200, and the user can draw the medicine out of the drainage portion 14 through the third channel 4 by using the third opening 113.

In another embodiment, illustrated in figures 1 and 8, nasogastric tube 100 'of gastrointestinal pressure reduction device differs from nasogastric tube 100 of gastrointestinal pressure reduction device illustrated in figure 1 in that nasogastric tube 100' of gastrointestinal pressure reduction device includes a second opening 112 'and a fourth opening 114' provided with a valve 6 and a valve 7, respectively, for preventing gas or liquid from flowing back out.

The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the scope of the present invention is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present invention, and such modifications and equivalents should also be considered as falling within the scope of the present invention.
