Abstract
The tailorable stomach tube comprises a stomach tube, the stomach tube is inserted and sealed, a liquid outlet hole is formed in the side surface of the stomach tube, a horn mouth plug is sleeved on the stomach tube, one end of the horn mouth plug is connected with a plug, the other end of the horn mouth plug is conical, and external threads are arranged at the conical position; the screw cap with the conical inner surface passes through the stomach tube and is in threaded connection with the plug head. The utility model discloses make the current horn mouth stopper of fixing at the stomach tube end movable, fix through the screw thread to use the screw thread to establish on conical surface, can carry out appropriate tailorring with exposed stomach tube according to patient's male stomach tube's length like this, remove the stopper to suitable position, fix the stopper on the stomach tube through the screw thread. Effectively reduce the exposed length of stomach tube, prevent the danger of extubation, make things convenient for the patient action.
Description
Technical Field
The invention relates to a medical instrument, in particular to a cuttable stomach tube.
Background
The stomach tube is inserted from the nostril, passes through the pharynx, reaches the stomach through the esophagus, is mostly used for drawing gastric juice, also can be used for infusing liquid into the stomach and provide necessary food and nutrition for patients, and care should be taken to avoid stomach tube pollution and stomach tube pull-out, which causes aspiration.
The insertion end of the existing stomach tube is closed and the side surface is provided with a liquid outlet hole; the other end of the stomach tube is fixed with a plug, the plug comprises a horn mouth fixed at the tail end of the stomach tube and a plug matched with the horn mouth, the stomach tube is sealed by the plug when the stomach tube is not used for nasal feeding, and the plug is opened and connected with the drip tube when the stomach tube is used for nasal feeding.
The currently clinically used nasogastric tubes are all integrated catheters with the length of 100-130cm, while the built-in length of a general adult is generally between 50-70cm, and about 1/3 catheters are usually exposed. Therefore, the exposed stomach tube is too long, so that encumbrance is caused to the patient, the appearance beauty of the patient is influenced, and the danger of accidental tube drawing is increased.
Disclosure of Invention
In order to solve the defects of the prior art, the utility model provides a gastric tube which can be cut, has reasonable structure and convenient use, and can effectively reduce the exposed length of the catheter.
In order to achieve the purpose, the invention adopts the following technical scheme:
the tailorable stomach tube comprises a stomach tube, the stomach tube is inserted and sealed, a liquid outlet hole is formed in the side surface of the stomach tube, a horn mouth plug is sleeved on the stomach tube, one end of the horn mouth plug is connected with a plug, the other end of the horn mouth plug is conical, and external threads are arranged at the conical position; the screw cap with the conical inner surface passes through the stomach tube and is in threaded connection with the plug head.
The stomach tube can be cut, and a sealing ring is arranged between the horn mouth plugging head and the stomach tube.
The stomach tube of can tailorring of foretell is equipped with L shape backstop in nut upper end cover, and the internal surface shape of backstop is unanimous with the surface shape of alar nose, and the internal diameter of backstop is less than the external diameter of nut.
The invention makes the prior bell-mouth plug fixed at the tail end of the stomach tube movable, fixes the plug through the screw thread, and uses the screw thread to be arranged on the conical surface, thus the exposed stomach tube can be cut properly according to the length of the stomach tube inserted by a patient, the plug is moved to a proper position, and the plug is fixed on the stomach tube through the screw thread.
The non-return device is used for being clamped at the outer side of the nasal alar, and can effectively prevent the stomach tube from retracting into the body.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
FIG. 2 is a schematic cross-sectional view of the present invention.
Labeled as: 1 infusion hole at the closed end of the stomach tube, 2 stomach tubes, 3 screw caps, 31 sealing rings, 4 external threads, a groove opening at the conical part of a 41 plug head, a conical surface of a 5 plug head, a 6 horn-mouth plug head, a 7 plug head and an 8 backstop.
Detailed Description
Referring to the attached drawing, can tailor the stomach tube, including stomach tube 2, the stomach tube inserts and seals and has seted up out liquid hole 1 in the side, and the cover is equipped with horn mouth chock plug 6 on the stomach tube, and horn mouth chock plug one end is connected with end cap 7, and the horn mouth chock plug other end is conical 6, is equipped with external screw thread 4 in conical department, and the internal surface passes stomach tube and chock plug threaded connection for conical nut 3, is equipped with between horn mouth chock plug and stomach tube and encloses 31.
The upper end of the screw cap is sleeved with an L-shaped backstop, the shape of the inner surface of the backstop is consistent with that of the outer surface of the nose wing, and the inner diameter of the backstop is smaller than the outer diameter of the screw cap.
After the stomach tube is inserted into the pharynx of a patient, the exposed part is cut as required, the plug head is fixed to the proper position of the stomach tube by loosening the screw cap, then the plug head is screwed with the screw cap, and the plug head is fixed on the stomach tube. Thereby effectively reducing the exposed length of the stomach tube, bringing convenience to the life of a patient, and avoiding the danger of unattractive appearance and tube pull-out caused by winding.
Before the plug is fixed, the backstop is required to be clamped at the outer side of the nasal alar, so that the stomach tube can be effectively prevented from retracting into the body to cause danger.
The thread fit of the conical surface, when the nut moves to one side of the fixed column, the conical part of the plug head extrudes towards the stomach tube, so that the plug head is pressed on the stomach tube, and the fixation with the stomach tube is realized. In this embodiment, the conical portion of the plug has two slots 41 along the axial direction of the plug, so that the conical portion can be properly displaced to press against the gastric tube when pressed.
The use of the plug is the same as that of the prior art, when the plug is not used, the plug is closed by the plug, and when the plug is used, the plug is opened to connect the gastric tube with other drip tubes.
In the invention, the plug head can move along the gastric tube, and a sealing ring is arranged between the plug head and the gastric tube in order to prevent liquid leakage when a transfusion tube is connected.
