Problems solved by technology

However, it has been found in clinical practice that sometimes it is still difficult to enter the esophagus with this method for patients who have been mechanically ventilated by endotracheal intubation.
The other main method is to use a laryngoscope to clamp the stomach tube head into the esophagus under clear vision, but because the endotracheal tube already occupies a part of the oral cavity, the operation is difficult and complicated, and it may cause damage to the oral cavity and other mucosal tissues while bleeding

Embodiment Construction

[0015] For gastric tubes of different diameters, the inner diameter of the catheter of the present invention can be made into corresponding sizes, generally 5.5-6.5mm, and the length is 25-40mm, and the material is transparent polyvinyl chloride.

[0016] In order to facilitate the observation of the depth of the catheter, a length scale can be engraved on the catheter.

[0017] The groove marks on both sides of the conduit of the present invention, the top of its cross-section is generally designed as a pointed shape, such as figure 2 As shown, it is convenient to tear the catheter tube lengthwise. The grooves on both sides of the catheter of the present invention are generally arranged symmetrically. The groove can be arranged on the outside of the tube body, or on the inside of the tube body.

[0018] The specific usage method is as follows:

[0019] 1 Inserted through the nose.

[0020] The patient fully instilled furama nasal drops into the nostril to prevent nasal m...

Abstract

The invention discloses an imbedding duct of clinical stomach tube in the medical apparatus technique domain, which is characterized by the following: the appearance of duct possesses nasopharynx oral anatomical physiological radian; the bore diameter is fit for stomach tube; there are two groove barmarks on bilateral pipe shaft to rip pipe shaft, wherein the front end is blunt rounded-entrance; the rear end possesses finger pinching-handle; the duct uses clarity polychloroethylene material to produce, which possesses scale mark; the duct puts in esophagus through nose or oral to form an artificial channel between nasal and esophagus; the soft stomach tube passes from duct to the stomach to rip stomach tube bobbin lead for making stomach tube separate form duct. The invention doesn't need patient to fit, which improves the success rate of imbedding stomach tube.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a catheter for placing a gastric tube in clinic. Background technique [0002] At present, medical workers place gastric tubes for patients mainly by passing the soft gastric tubes through the nasal cavity into the oral cavity, then through the esophagus and finally into the gastric cavity. The section from the mouth to the mouth of the esophagus is a difficult point for gastric tube placement. Due to the complex anatomical structure in the oral cavity, it is not a tubular structure, and the gastric tube is soft, so it is difficult to enter the esophagus in the predetermined direction. [0003] Clinically, for awake cooperative patients, the gastric tube can be swallowed into the esophagus and finally into the gastric cavity through the patient's active cooperation in swallowing. [0004] However, for uncooperative patients, such as comatose or sedated uncon...
