Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cardiovascular intervention trays, in particular to a device for preventing nasal intestinal tube blockage. BACKGROUND

[0002] The nasal intestinal tube is inserted through the nasal cavity, passes through the pharynx, esophagus and stomach, and finally reaches the duodenum or jejunum to assist medical feeding. It is mainly used for nutritional support or drug delivery for patients who cannot eat orally or have gastric emptying disorders. It provides necessary nutrients, including water, electrolytes, proteins, fats, vitamins and minerals, etc. for patients, helps patients recover physical strength and promotes recovery. Preventing nasal intestinal tube blockage is an important part of clinical nursing, especially in critically ill and postoperative patients. The patency of the nasal intestinal tube directly affects the nutritional supply and treatment effect of the patient.

[0003] As disclosed in CN215133656U, a simple device for preventing nasal intestinal tube blockage is disclosed, which comprises a syringe connecting pipe, which comprises a pipe body part and a connecting part. The pipe body part is connected with the connecting part. A plurality of first water outlets are provided on the pipe wall of the pipe body part. A funnel-shaped transition part is formed between the connecting part and the pipe body part. A brush head comprises bristles and a connecting pipe. The bristles are connected with the connecting pipe. The connecting pipe is connected with the pipe body part. A plurality of second water outlets are provided on the pipe wall of the connecting pipe. Since the connecting pipe of the pipe body part and the brush head are respectively inclined and provided with a plurality of first water outlets and second water outlets, by rotating the brush head, the impurities adhering to the wall of the nasal intestinal tube are brushed off. At the same time, normal saline is injected. The normal saline can be ejected outward from the first water outlets and the second water outlets to flush the nasal intestinal tube, thereby preventing pipe blockage. The production cost is low and mass production is facilitated.

[0004] As disclosed in CN209751703U, a nasal intestinal tube blockage dredging device is disclosed, which comprises a support frame, a pressurizing assembly, a hollow needle, a connecting pipe and a nasal intestinal tube. The support frame comprises a first support plate, a support and a second support plate. The first support plate and the second support plate are connected at the two ends of the support. The pressurizing assembly is arranged on the first support plate. One end of the pressurizing assembly is located outside the first support plate. The other end of the pressurizing assembly is located between the first support plate and the second support plate. The hollow needle is inserted into the connecting pipe and tightly matches with the connecting pipe. The nasal intestinal tube is inserted into the connecting pipe away from the hollow needle. A hole is formed in the second support plate. The hollow needle is inserted into the hole. The pressurizing assembly can push the piston of the hollow needle to advance. This nasal intestinal tube blockage dredging device can increase the pressure of the piston of the hollow needle. It can not only assist the piston of the hollow needle to advance, but also prevent the intestinal tube from falling off or liquid from leaking from the connection between the nasal intestinal tube and the hollow needle.

[0005] A nasal-gastric tube and nasal-intestinal tube blockage treatment combined kit is disclosed in publication CN215274620U, which comprises a main injection syringe, a side injection syringe, and a three-way tube. The three-way tube is an axially compressible three-way tube, with a main port and an injection port at its two axial ends, and a side port on the side. The main injection syringe and the side injection syringe are connected to the main port and the side port through treatment tubes, and the injection port is used to connect the nasal-gastric tube or the nasal-intestinal tube. The three-way tube adopts an axially compressible three-way tube, and the three outlets can be opened and closed, which facilitates the disassembly of the three-way tube and makes the cleaning more effective through extrusion. The treatment tube adopts a PU hose with curved ridges on the inner wall, which has excellent anti-clogging effect and improves the use effect.

[0006] Nasal-intestinal tubes are usually long and have a small inner diameter. Although this structure facilitates insertion and reduces irritation to the nasal cavity, it increases the risk of nutrient solution or drugs adhering to the inner wall of the tube cavity, thereby causing the tube cavity to narrow and increasing the likelihood of blockage. Thick nutrient solution is prone to adhere to the tube wall during infusion, especially during long-term continuous infusion, which is more likely to form a coagulation state, leading to blockage. Some drugs (such as acidic drugs) may react with nutrient solution after mixing, forming clots or precipitates and increasing the risk of blockage. Some existing devices for preventing nasal-intestinal tube blockage are not convenient for treating the medium input into the nasal-intestinal tube, and are not convenient for dredging the medium transported in the nasal-intestinal tube to prevent sedimentation. The effect of preventing nasal-intestinal tube blockage is limited.

[0007] In view of the above, it is particularly important to design a device for preventing nasal-intestinal tube blockage. SUMMARY
