Description

Ventilation, decompression and drainage device in anus and intestine

Technical Field

The utility model relates to the technical field of medical treatment, in particular to a transanal and intestinal ventilation and pressure reduction drainage device.

Background

In ICU, up to 62% of patients present with at least one gastrointestinal symptom for more than 1 day. There is also increasing evidence that gastrointestinal function is associated with a prognosis, with patients with more severe symptoms having a worse prognosis the longer the duration of gastrointestinal dysfunction. Also, it is common for different gastrointestinal symptoms to occur simultaneously, and it has been reported that up to 60% of mechanically ventilated patients can observe different gastrointestinal signs: up to 62% of patients exhibit at least one gastrointestinal symptom for more than 1 day, and about 20% of patients exhibit three or more gastrointestinal symptoms during the ICU, and 6% of patients may exhibit three or more gastrointestinal symptoms if considered to occur simultaneously within one day. Gastrointestinal dysfunction greatly increases the nursing burden of patients and reduces the quality of life. How to keep the intestinal tract unobstructed and recover the function of the gastrointestinal tract is a difficult problem. Thirdly, there are more severe patients who have gastrointestinal dysfunction conditions such as diarrhea, constipation after using enteral nutrition, and most doctors clinically use repeated enema of the anal canal intubation tube and the mode of placing the tracheal intubation tube into the anus for drainage, which brings the patients to feel sensitive and uncomfortable. And as with the anal canal, an extended dwell time can cause irreversible damage to the anal sphincter. And the existing anorectal decompression drainage tube for severe patients is usually made of harder materials, so that the risk of iatrogenic intestinal tube injury exists. For example, patent No. CN204932553U discloses a colon decompression tube which can only perform the functions of exhausting air and reducing pressure, and for example, patent No. CN106730092A discloses an intestinal tract cleaning tube, but because the actual length of the intestinal tract is less than 1 meter, the feces cannot be effectively drained before absorbing water through the colon, so repeated enema is still needed, and the design is suitable for patients with megacolon rather than most patients with intestinal tract dysfunction; furthermore, the drainage device such as the health body dredging device is a flexible tube, but due to the contraction effect of the anal sphincter (especially, the contraction of the anal sphincter is caused when the wound of some operation patients is painful), the flexible tube can be clamped by the anus, and even the patient is required to cooperate to open the anal sphincter forcibly when defecating; the utility model can not assist the patient with abdominal distension to exhaust and relax bowels.

Disclosure of Invention

In order to solve the problems that the existing medical equipment can not effectively improve the gastrointestinal tract function of a patient, the drainage and flushing are insufficient and the like, the utility model provides a transanal and intestinal ventilation and decompression drainage device.

The technical scheme adopted by the utility model is as follows: the tube is sent into the intestinal tract by the anus under the colonoscope or directly beside the bed, specifically a tube body of 150 plus 250cm, one end of the outer side of the tube body anus is provided with a liquid inlet tube, a liquid outlet tube and an air bag tube, the air bag is positioned near the tail end of the tube body in the intestinal tract, the air bag is fixed at the ileocecal part or the colon ascending part (the water injection amount in the air bag is adjusted according to the intestinal tract condition of a patient and is generally about 10-20ml), so that the anus combining part (the position of the tube body material is called as the anus combining part in the description) is fixed near the anus of the patient, and the main tube body is provided with side holes.

The optimized pipeline from the anus joint part to the tail end of the intestinal cavity is made of harder materials, and the pipeline from the anus joint part to the liquid inlet pipe, the liquid outlet pipe and the air bag pipe is made of softer materials.

And optimally, the side holes distributed on the main pipe body are distributed in a staggered manner.

Preferably, the air inlet pipe can be connected with an oxygen pipe for colon ventilation.

The application of the transanal and intestinal ventilation and decompression drainage tube is applied to severe patients with gastrointestinal dysfunction.

The utility model has the beneficial effects that: the intestinal contents and intestinal gas can be flushed and drained before the feces are not dried, so that obstruction at the colon part is avoided. The design of the anus joint part, the pipeline from the anus joint part to the tail end of the intestinal cavity is made of hard materials, and the pipeline from the anus joint part to the liquid inlet pipe, the liquid outlet pipe and the air bag pipe is made of soft materials. During drainage and flushing, the pipeline is slightly pulled out, so that the hard pipe expands the anus part and the pipeline is smooth; when the catheter is kept in place, the catheter is pushed in lightly, the anus is contracted by means of the soft material, the anal sphincter is prevented from being influenced for a long time and is loosened, the anal sphincter can be effectively protected, and the catheter can be kept in place for a long time. And can carry out a plurality of other medical operations such as colon administration, fecal bacteria transplantation, colon dialysis and even colon ventilation and the like through the pipeline, thereby reducing the pain of patients caused by repeated intubation and clystering and other iatrogenic risks such as intestinal perforation and the like.

Detailed Description

In the embodiment shown in fig. 2, when a critically ill patient with gastrointestinal dysfunction is operated, an appropriate type of the intestinal tract cleaning tube can be selected according to the physical constitution of the patient, the width and the length of the intestinal tract. The utility model can be inserted blindly at the bedside or placed under the guidance of the colonoscope more accurately. The balloon is not inflated during intubation, and the intubation is not affected at this time. When the air bag at the front end of the pipeline reaches the vicinity of the ascending colon and the ileocecal part and the anus combining part reaches the anus, the air bag is inflated and fixed to prevent the pipeline from slipping. The effects of enema, administration, ventilation and the like are achieved for the patient through the liquid inlet pipe. Negative pressure drainage is carried out from the liquid outlet pipe when intestinal flatulence and intestinal contents are drained. The tail end of the pipeline is deep into the ascending colon and the ileocecal part, so the flushing drainage effect is better, and the pipeline is not easy to block.

In fig. 4, at the position of the anus joint portion, the pipeline from the anus joint portion to the tail end of the intestinal cavity is made of a harder material, and the pipeline from the anus joint portion to the liquid inlet pipe, the liquid outlet pipe and the air bag pipe is made of a softer material. When in drainage and flushing, the pipeline is slightly pulled out, so that the hard pipe expands the anus part and the pipeline is smooth; when the anal sphincter is kept in place, the anal sphincter is slightly pushed in, and the anal sphincter is shrunk by the soft material, so that the anal sphincter is prevented from being influenced for a long time and is prevented from being loosened.

The above-mentioned embodiments only express the embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
