[0028] Please refer to Figure 1-2, a multi-functional connecting pipe provided in this embodiment includes a connecting pipe 1. Side holes are provided on the side of the connecting pipe 1. A one-way valve 11 is installed on the connecting pipe 1, and the one-way valve 11 is located on a section from the side hole to one end of the connecting pipe; a valve assembly 2, the valve assembly 2 includes a side pipe 21 and a three-way valve 22. The side pipe 21 is installed on the side hole, and the three-way valve 22 is installed at the side hole of the connecting pipe 1. The three-way valve 22 connects the connecting pipe 1 and the side pipe 21. A rubber cover 23 is installed on the side pipe 21; a joint 3 includes a plug joint 31, a rubber sleeve 32 and a clamp 33. The plug joint 31 is connected to the other end of the connecting pipe 1, and the rubber sleeve 32 is sleeved at the connection between the connecting pipe 1 and the plug joint 31.

[0029] Specifically, the two ends of the connecting pipe 1 are respectively connected to a drainage bag and a gastric or intestinal tube. The side pipe 21 installed on the side hole opened on the side of the connecting pipe 1 is used for injecting drugs or other treatments. The drainage bag is used to suck out body fluids in the patient's stomach or intestine. The three-way valve 22 controls the two pipes of the side pipe 21 and the connecting pipe 1. When drug injection is not required, turn the three-way valve 22, and the two sides of the connecting pipe 1 are connected, and the drainage bag and the gastric and intestinal tubes are connected for drainage. When drug injection is required, turn the three-way valve 22 again to connect the side pipe 21 and the pipe of the connecting pipe 1 leading to the gastric and intestinal tubes, and the pipe of the connecting pipe 1 leading to the drainage bag is closed to prevent the drug from flowing into the drainage tube. In the actual use process, medical staff usually use a syringe to inject drugs into the gastric and intestinal tubes. A rubber cover 23 is installed on the side pipe 21, and medical staff can directly insert the syringe on the rubber cover 23 for drug injection. After the injection is completed, turn the three-way valve 22 back again to continue the original treatment. Installing a one-way valve 11 in the middle part of the connecting pipe 1 connecting the drainage bag and the side hole can avoid body fluid backflow and prevent the medicinal liquid injected from the side pipe 21 from flowing into the drainage bag. The joint 3 is used for the connection between the connecting pipe 1 and the gastric and intestinal tubes. The gastric and intestinal tubes have different sizes. When in use, insert the plug joint 31 into the gastric and intestinal tube, then put the rubber sleeve 32 on the gastric and intestinal tube, and tighten the clamp 33 to complete the connection. This device makes it more convenient for medical staff to perform drug injection operations. The device has a simple structure and can prevent the backflow of drainage fluid. At the same time, it is more tightly connected to the gastric and intestinal tubes. The injection method of inserting the syringe into the rubber cover 23 is more scientific and hygienic, providing support for other treatments that need to be carried out during the drainage treatment process by medical staff and reducing the work burden of medical staff.

[0030] In some possible implementation manners, a collar 24 is installed on the side pipe 21, and the rubber cover 23 is detachably installed on the side pipe 21 through the collar 24.

[0031] Specifically, during actual use, medical staff may need to inject drugs from time to time and multiple times. When the number of drug injections is excessive, the injection hole of the rubber cap will be difficult to close due to too many holes caused by excessive injection times. Medical staff can disassemble and replace the rubber cap 23 to increase the number of times the device can be used.

[0032] In some possible embodiments, the side tube 21 is a flexible tube, and the length of the side tube 21 is not less than 3 cm.

[0033] Specifically, the syringe needle has a certain length. With a side tube 21 length of 3 cm, the injection head of the syringe can be inserted as much as possible, and when medical staff inject drugs, the drugs are not likely to leak.

[0034] In some possible embodiments, the rubber cap 23 is screwed onto the collar 24; the length of the connecting pipe 1 is not less than 20 cm; the connecting pipe 1 is made of medical polyvinyl chloride material.

[0035] Specifically, the screw connection is tighter, and the disassembly and installation are convenient, and the rubber cap 23 will not accidentally slip off; the connecting pipe 1 has a certain length to better connect the drainage bag and the stomach and intestinal tubes. The lengths of the stomach and intestinal tubes are limited. A connecting pipe 1 not less than 20 cm increases the prevention range of the drainage bag and is more convenient to use. The connecting pipe 1 needs to drain gastric drainage fluid or inject liquid medicine. The medical polyvinyl chloride material has certain corrosion resistance and will not be eroded due to long-term use. At the same time, it has a certain transparency, which is convenient for medical staff to observe the flow direction of the drainage fluid or liquid medicine.

[0036] In some possible embodiments, a vial puncture device 12 is connected to one end of the connecting pipe 1. A protective cover 13 is sleeved on the vial puncture device 12.

[0037] Specifically, the connecting pipe 1 needs to be connected to the drainage bag. The drainage treatment time of the patient is relatively long, and the drainage bag needs to be replaced multiple times. The connecting pipe 1 also needs to be connected to the drainage bag multiple times. Setting a vial puncture device 12 at one end of the connecting pipe 1 makes it more convenient to connect to the drainage bag through the vial puncture device 12. The protective cover 13 on the vial puncture device 12 is used to protect the vial puncture device 12 when it is not in use.

[0038] In some possible embodiments, the switch of the three-way valve 22 is a rotating handle; the rotating handle is made of plastic material.

[0039] Specifically, the switch of the three-way valve 22 being a rotating handle is easier to control. Medical staff can just turn the rotating handle. The rotating handle being made of plastic material makes the overall weight of the device lighter and will not cause a large burden on the patient, resulting in patient discomfort.
