[0026] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0027] Reference Figure 1-4The embodiment of the present invention is a sampler for gastroenterology nursing, which includes a first tube body 1, a second tube body 2 and an inflatable bag 14. A piston 3 is provided inside the first tube body 1, and a pull rod 4 is fixedly connected to the upper end of the piston 3. A hand-held block 5 is fixedly connected to the upper end of the pull rod 4, which is used to pull the hand-held block 5 to drive the pull rod 4 to pull the piston 3, so that negative pressure is generated inside to pump. A limiting block 6 is fixedly connected to the upper inner wall of the first tube body 1 to prevent the piston 3 from being pulled too much and falling off the first tube body 1. The number of limiting blocks 6 There are two, and a first one-way valve 7 is provided on the inner bottom wall of the first tube body 1 for controlling the inflow of exfoliated cells. The lower end of the first tube body 1 is fixedly connected to a first conduit 8, and a second one-way valve 9 is provided on the side of the first tube body 1 for controlling the detached cells to flow into the collection cup 11. The right side of the second one-way valve 9 is fixedly connected to a second conduit 10, and the head of the second conduit 10 is fixedly connected to the collection cup 11. The outer surface of the first tube body 1 is fixedly connected to a first fixing ring 12 for fixing the first tube body 1 and the third conduit 13.

[0028] The lower end of the inflatable bag 14 is fixedly connected to the third conduit 13. The surface of the third conduit 13 is provided with an air valve 15 for controlling the discharge of the gas inside the rubber airbag 20. The inside of the air valve 15 is provided with a valve plate 16. The side of the valve plate 16 is fixedly connected to a valve stem 17. The head of the valve stem 17 is fixedly connected to a rotating head 18. The head of the third conduit 13 is fixedly connected to a vent pipe 19. The head of the vent pipe 19 is fixedly connected to the rubber airbag 20. Pressing the inflatable bag 14 allows the generated gas to be discharged into the vent pipe 19 through the third conduit 13 to inflate the rubber airbag 20. Expansion, the head of the first catheter 8 is fixedly connected with a guide hose 21 for guiding the flow of exfoliated cells, the ventilation tube 19 and the guide hose 21 are both made of PVC plastic soft material, the filter plate 23 is fixed to the inside of the second tube body 2 through the fixing seat 22, and the inside of the second tube body 2 is provided with a filter plate 23 for filtering out food residues on the esophageal wall, the lower end of the second tube body 2 is fixedly connected with a fourth catheter 24, and the outer surfaces of the second tube body 2 and the ventilation tube 19 are fixedly connected with a second fixing ring 25 for fixing the second tube body 2 to the ventilation tube 19.

[0029] Working principle: When in use, the second tube body 2 is placed in the patient's esophagus, and the inflatable bag 14 is pressed so that the generated gas is discharged into the ventilation tube 19 through the third catheter 13 to inflate the rubber airbag 20, so that the rubber airbag 20 expands and blocks the esophagus, and the exfoliated cells and gastric juice are retained on the rubber airbag 20. The hand-held block 5 is pulled to drive the pulling rod 4 to pull the piston 3 upward, so that negative pressure is generated inside the first tube body 1, thereby sucking the exfoliated cells and gastric juice through the fourth catheter 24. The limit block 6 prevents the piston 3 from being pulled too much and falling off the first tube body 1. The filter plate 23 filters the esophageal wall residue. When it is pulled upward, the first one-way valve 7 opens and the second one-way valve 9 closes, and the mixture of exfoliated cells and gastric juice flows into the first tube body 1 through the diversion hose 21 and the first conduit 9. When it is pressed downward, the first one-way valve 7 closes and the second one-way valve 9 opens, and the mixture of exfoliated cells and gastric juice flows into the collection cup 11 through the second conduit 10. After the sampling is completed, the rotating head 18 is rotated to drive the valve stem 17 to open the valve plate 16, so that the gas in the rubber airbag 20 is discharged through the air valve 15, thereby removing the second tube body 2.

[0030] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
