Tension-type nasogastric tube plug component

Abstract

The invention discloses a tension-type nasogastric tube plug component, which is characterized in that: a rubber orifice element is welded on the inlet end of a nasogastric tube, small end of an inner taper hole of the rubber orifice element is opened, the rubber orifice element extends out to form a soft connection rubber sheet, the soft connection rubber sheet forms a movable connection with a nut bushing at an assembling place between a hole and a shaft, an outer thread of a cone positioning screw and an inner thread of the nut bushing form a thread pair, the end part of the nut bushing is provided with a back-off button, a tension sealing ring is sleeved on the middle part of a shaft of the cone positioning screw, the right part of the cone positioning screw is of a manual screw-closure part, and an inner taper hole of the tension sealing ring is sealed with the outer cone body of the cone positioning screw in a dislocation way. Through the movement of the thread pair, the outer cone body which is matched with the inner cone body of the tension sealing ring in a sealing way moves in the axial direction so as to realize the sealing and the positioning between the outer circular surface of the tension sealing ring and the inner taper hole of the rubber orifice element, so the duration of the tube plug and the safety reliability of the nasogastric tube during the application can be improved.

Description

technical field [0001] The invention relates to a medical nursing appliance, in particular to a medical gastric tube stopper assembly for supporting various types of gastric tubes. Background technique [0002] Gastric tubes are widely used in medical clinics. From the perspective of various gastric tubes currently used in hospitals or home care patients, especially nasal feeding gastric tubes, the tube plugs for the gastric tube nozzles are usually node-shaped and tapered, and it is consistent with the inner diameter of the gastric tube nozzle. After the conical nodular fit, the inside of the pipeline can be isolated from the outside world, so as to prevent bacterial infection and the outflow of food in the stomach. Yet this gastric tube stopper is due to having 6 to 8 times of every day dialing out and stuffing in nursing patient, and the frequency of use is higher, often is about ten days to the use of gastric tube, and this tube stopper will be with the mouth of the tub...

Problems solved by technology

Yet this gastric tube stopper is due to having 6 to 8 times of every day dialing out and stuffing in nursing patient, and the frequency of use is higher, often is about ten days to the use of gastric tube, and this tube stopper will be with the mouth of the tube. Connector splits and becomes lost or unusable, resulting in scrapping of gastric tube
