Description

Safe and reliable stomach tube

Technical Field

The utility model relates to the technical field of stomach tube structures, especially a safe and reliable stomach tube.

Background

Gastric tubes, also known as nasogastric tubes, are used primarily for draining gastric juices and for infusing absorbable water and nutritional fluids into the stomach of a patient. The structure of current stomach tube is shown in figure 1, and it includes stomach tube main part 1 and sets firmly sleeve pipe 2 at stomach tube main part 1 top, sleeve pipe 2 and stomach tube main part 1 intercommunication have set firmly flexonics area 5 on the sleeve pipe 2, and the other end of flexonics area 5 has set firmly apron 6, and the bottom of apron 6 has set firmly port stopper 7, and port stopper 7 cartridge is in the top port of sleeve pipe 2. During the use, medical staff passes nasal cavity, esophagus in order with the lower port of stomach tube main part 1 and stretches into in patient's stomach, upwards pulls apron 6 afterwards so that port stopper 7 extracts from the sleeve pipe 2 in, then medical staff injects a certain amount of nutrient solution into sleeve pipe 2, fills in port stopper 7 in the top of sleeve pipe 2 again at last in to the patient input nutrient solution has been realized. However, although such a gastric tube enables the infusion of a patient with a nutrient solution, the following drawbacks still exist: 1. if the injected nutrient solution has a certain temperature, the pressure in the stomach of the patient is increased, and then the port plug 7 is bounced off, and the injected nutrient solution is finally sprayed out from the top port of the sleeve 2 along the stomach tube main body 1 and the sleeve 2, so that the defect of poor feeding effect exists. 2. When a patient coughs, the intra-abdominal pressure is increased, so that the port plug 7 is bounced, and the defect of poor feeding effect and potential safety hazard exist. Therefore, a safe and reliable gastric tube preventing the port plug from springing open is needed.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provide a safe and reliable stomach tube which has compact structure, prevents the port plug from bouncing off, is safe and reliable, can relieve the pain of a patient during gastric lavage and has simple operation.

The purpose of the utility model is realized through the following technical scheme: the utility model provides a safe and reliable's stomach tube, it includes stomach tube main part and sleeve pipe, be provided with the external screw thread on the cylinder of stomach tube main part upper end, be provided with the internal thread on the sheathed tube inner wall, the external screw thread threaded connection of sheathed tube internal thread and stomach tube main part, sleeve pipe and stomach tube main part intercommunication, the flexonics area has set firmly on the sheathed tube right side outer wall, and the other end of flexonics area has set firmly the apron, and the bottom of apron has set firmly the port stopper, and port stopper cartridge is in sheathed tube top, and the welding has the fixing base on the sheathed tube left side outer wall, has seted up the blind hole on the left end face of fixing base, the left end part of apron is buckled downwards, and the welding has the bolt with blind hole matched with on the right-hand member.

The bolt, the pulling plate and the fixing seat are plastic parts.

The flexible connecting belt is a soft plastic part.

The blind hole is in interference fit with the plug pin.

The pulling plate is horizontally arranged.

The utility model has the advantages of it is following: the utility model discloses compact structure, prevent that the port stopper from popping open, safe and reliable, easy operation.

Detailed Description

The invention will be further described with reference to the accompanying drawings, without limiting the scope of the invention to the following:

as shown in fig. 2 to 5, a safe and reliable stomach tube comprises a stomach tube main body 1 and a sleeve 2, wherein an external thread 3 is arranged on the cylindrical surface of the upper end portion of the stomach tube main body 1, an internal thread 4 is arranged on the inner wall of the sleeve 2, the internal thread 4 of the sleeve 2 is in threaded connection with the external thread 3 of the stomach tube main body 1, the sleeve 2 is communicated with the stomach tube main body 1, a flexible connecting belt 5 is fixedly arranged on the outer wall of the right side of the sleeve 2, the flexible connecting belt 5 is a soft plastic part, a cover plate 6 is fixedly arranged at the other end of the flexible connecting belt 5, a port plug 7 is fixedly arranged at the bottom of the cover plate 6, the port plug 7 is inserted into the port of the sleeve 2, a fixed seat 8 is welded on the outer wall of the left side of the sleeve 2, a blind hole 9 is arranged on the left end face of the fixed, the bolt 10 cartridge is in blind hole 9, and blind hole 9 and bolt 10 interference fit, the left end welding of kink has arm-tie 11, and arm-tie 11 level sets up. The bolt 10, the pulling plate 11 and the fixed seat 8 are all plastic parts.

The working process of the utility model is as follows:

during the use, medical staff passes the nasal cavity in order with the lower port of stomach tube main part 1, the esophagus and stretches into in patient's stomach, afterwards to pulling arm-tie 11 so that bolt 10 extracts from blind hole 9, medical staff upwards pulls up arm-tie 11 after extracting, so that port stopper 7 extracts from the top of sleeve pipe 2 intraorally, then medical staff injects a certain amount of nutrient solution into the top of sleeve pipe 2 intraorally, the back of finishing injecting, medical staff fills in port stopper 7 again in the top of sleeve pipe 2 intraorally, later with bolt 10 cartridge in the blind hole 9 of fixing base 8, thereby realized for patient's input nutrient solution. Due to the interference fit of the bolt 10 and the blind hole 9, the pressure in the stomach is prevented from rising due to the temperature of the nutrient solution, so that the port plug is effectively prevented from being bounced off, the nutrient solution is prevented from flowing back and being discharged, and the safety and reliability are realized. In addition, because the interference fit of the plug pin 10 and the blind hole 9 also avoids the increase of the intra-abdominal pressure when the patient coughs, the port plug 7 is bounced open, and the feeding safety is further ensured.

When the whole gastric tube needs to be cleaned, the sleeve 2 only needs to be screwed off from the gastric tube main body 1, and the sleeve 2 and the gastric tube main body 1 are cleaned independently. In addition, only need to change alone when sleeve pipe 2 or stomach tube main part 1 damage the part that has damaged, need not to change whole stomach tube to use cost has been saved.

The foregoing is illustrative of the preferred embodiments of the present invention, and it is to be understood that the invention is not limited to the precise forms disclosed herein, and that various other combinations, modifications, and environments may be resorted to, falling within the scope of the invention as defined by the appended claims. But that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention, which is to be limited only by the claims appended hereto.
