[0004] 1. Gastric tube connectors: During drainage, flushing, medication administration, or nasogastric feeding, it is necessary to repeatedly insert or connect negative pressure drainage tubes, flushing tubes, syringes, etc. Repeated connection can easily cause the inner diameter of the gastric tube end to increase, and loose connection can lead to detachment and leakage.

[0005] 2. During the nursing process, patients often pull out their gastric tubes. After the gastric tubes are pulled out, they need to be reinserted, which increases the patient's pain and the workload of the nursing staff. Utility Model Content

[0006] To address the problems mentioned in the background section, this invention provides a Y-type threaded gastric tube. The tube clamping component uses a rotating threaded clamping rod to drive a clamping block to hold the gastric tube, which is then fixed in place by a limiting rod, facilitating adjustment and preventing displacement and unnecessary damage during use. A three-way valve allows for connection between the gastric tube's tip and either the inlet or outlet connector. The inlet and outlet connectors are detachably connected to a syringe and a negative pressure drainage tube via external threads. This threaded connection prevents repeated connection and connection from causing the gastric tube's inner diameter to increase and leak.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a Y-type threaded connector gastric tube, comprising a protective device and a gastric tube. The protective device has an arc-shaped structure, and a groove is provided on the inner side of the protective device.

An inlet connector and an outlet connector are connected to the end of the gastric tube. A three-way valve for connecting the inlet connector and the outlet connector is provided inside the end of the gastric tube. The outer ends of the inlet connector and the outlet connector are provided with external threads, and protective caps are connected to the ends of the inlet connector and the outlet connector.

[0008] As a preferred embodiment of the Y-type threaded connector gastric tube of this utility model, the top and bottom of the tube clamping component are slidably disposed in the groove of the protective device by a slider; threaded clamping rods are connected to both sides of the tube clamping component by a rotating threaded part, one end of the threaded clamping rod is inserted into the tube clamping component and connected to a clamping block, and the tube clamping component clamps the gastric tube by the clamping block.

[0009] As a preferred embodiment of the Y-type threaded gastric tube of this utility model, the top of the protective device is provided with several limiting holes, and a limiting rod is inserted into the limiting holes to limit the connection with the top of the tube clamping component.

[0010] As a preferred embodiment of the Y-type threaded gastric tube of this utility model, the outer ends of the inlet and outlet connectors are detachably connected to the syringe and the negative pressure drainage tube via external threads.

[0011] As a preferred embodiment of the Y-type threaded gastric tube of this utility model, the negative pressure drainage tube is equipped with a switch valve.

[0012] As a preferred embodiment of the Y-type threaded gastric tube of this utility model, the three-way valve is provided with a switch knob for controlling the connection between the gastric tube and one of the inlet and outlet connectors.

[0013] As a preferred embodiment of the Y-type threaded gastric tube of this utility model, the protective device is provided with a tightening strap.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model's tube clamping component allows the gastric tube to slide left and right within the groove of the protective device via a slider. The tube clamping component uses a rotating threaded clamping rod to drive the clamping block to hold the gastric tube, facilitating angle adjustment by nursing staff. Furthermore, a limiting rod through a limiting hole limits and fixes the tube clamping component, preventing displacement and unnecessary damage during use. This further prevents patients from pulling out the gastric tube, reducing patient pain and workload for nursing staff.

[0016] The gastric tube is equipped with a three-way valve at its end for connecting the inlet and outlet connectors. The switch knob on the three-way valve controls whether the front end of the gastric tube is connected to the inlet or outlet connector.

Then, the protective garment 1 is secured to the patient's head with a tightening strap. The tube clamping component 3 can drive the gastric tube 2 to slide left and right in the groove 11 of the protective garment 1 through a slider. The tube clamping component 3 clamps the gastric tube 2 by rotating the threaded clamping rod 32, which drives the clamping block 31. This facilitates the angle adjustment operation by the nursing staff. Then, the tube clamping component 3 is fixed by the limiting rod 13 through the limiting hole 12 to prevent displacement and unnecessary damage during use. This further prevents the patient from pulling out the gastric tube, reduces the patient's pain, and also reduces the workload of the nursing staff.

[0036] The end of the gastric tube 2 is equipped with a three-way valve 23 for connecting the inlet connector 21 and the outlet connector 22.
