Abstract

The invention relates to a multi-orifice nasogastric tube with a fixing device and a guide wire. The multi-orifice nasogastric tube comprises a catheter body, the guide wire, and a support device. Thefront end of the catheter body is provided with a sealed end; the guide wire is arranged in the catheter body; the front end of the guide wire is evenly provided with a plurality of brush rods; the end of each brush rod is provided with a brush head; the catheter body is sleeved with a fixing sleeve; the fixing sleeve is symmetrically provided with two V-shaped gaps; the support device includes asupport sleeve, a plurality of support ribs and a support wire frame; the fixing sleeve is sleeved with a support sleeve; the support ribs are arranged evenly on the outer side of the support sleeve;the support wire frame is fixed outside the support ribs. The front end of the catheter body is provided with a limiting guide ball shell; the front end of the guide wire is also provided with a guide ball; puncture to the nose, esophagus and intestinal mucosa can be avoided; the catheter body can be fixed effectively; the fixing device helps conveniently maintain the nasal cavity in the tube placement position; the front end of the guide wire is provided with the brush heads, side holes of the catheter body and the inside of the catheter body can be effectively dredged.

Description

technical field [0001] The invention relates to the technical field of oncology, in particular to a porous nasogastric tube with a fixing device and a guide wire. Background technique [0002] At present, in the clinical application of hospitals, gastric tubes are mainly used for gastrointestinal decompression in thoracic and abdominal patients during surgery, enteral nutrition supply and gastric lavage for critically ill patients. Currently, there are single-lumen gastric tube, double-lumen gastric tube, and triple-lumen gastric When performing gastrointestinal decompression, it lasts for a long time, up to 42 days. In order to prevent the gastric tube from prolapse, the gastric tube is usually fixed on the patient's face with adhesive tape, but the nasal cavity on the side where the gastric tube is inserted is blocked, which affects breathing. , when maintaining the nasal cavity for the patient, the adhesive tape needs to be removed, and then fixed after the nursing is com...

[0002] At present, in the clinical application of hospitals, gastric tubes are mainly used for gastrointestinal decompression in thoracic and abdominal patients during surgery, enteral nutrition supply and gastric lavage for critically ill patients. Currently, there are single-lumen gastric tube, double-lumen gastric tube, and triple-lumen gastric When performing gastrointestinal decompression, it lasts for a long time, up to 42 days. In order to prevent the gastric tube from prolapse, the gastric tube is usually fixed on the patient's face with adhesive tape, but the nasal cavity on the side where the gastric tube is inserted is blocked, which affects breathing. , when maintaining the nasal cavity for the patient, the adhesive tape needs to be removed, and then fixed after the nursing is completed, which is inconvenient to operate; the current single-lumen or double-lumen gastric tube is made of rubber, silicone and other materials, and the tube body is too soft to be used Inserting the tube under direct vision will easily cause damage to the nose, esophagus and intestinal mucosa, causing some complications such as inflammatory edema, bleeding, ulcers, etc., causing pain and discomfort to the patient, and aggravating the patient's condition; the existing gastrointestinal tube is easy to Blockage occurs. Once blocked, it must be replaced, increasing the economic burden of the patient. Repeated extubation and intubation will also cause harm to the patient.
