Description

Technical Field

[0001] The utility model belongs to the technical field of medical auxiliary facilities, in particular to a nasogastric feeding device for postoperative rehabilitation. Background Art

[0002] After surgery, patients with cavity diseases are unable to chew and swallow food orally, and usually need to use nasogastric feeding to assist in eating. Nasogastric feeding is to use a nasogastric tube to pass through the nasal cavity into the patient's stomach, and inject food, water and medicine into the nasogastric tube to ensure that the patient obtains the necessary nutrients.

[0003] During nasogastric feeding, the nasogastric tube usually needs to be left in the patient's nasal cavity and esophagus for a period of time. The tube is left in place for a long time, and flocs are easily attached to the tube wall, causing the tube to be blocked. In addition, the lumen of the nasogastric tube is relatively thin, and the incidence of tube blockage is high when infusing high-concentration nutrient solution. Therefore, the tube needs to be flushed before, during, and after the nasogastric feeding operation, which is time-consuming and laborious.

[0004] At present, the nasogastric feeding syringe is often used to extract the flushing fluid to flush the nasogastric feeding tube. If the tube is blocked, it is necessary to connect a needle to suck cola or sodium bicarbonate or urokinase to flush the tube, which causes a large clinical workload. In addition, improper operation during the flushing process can easily cause contamination. Replacing a new nasogastric feeding tube or connecting a new flushing needle will increase the patient's pain. Utility Model Content

[0005] The utility model aims to provide a nasogastric feeding device for postoperative rehabilitation. A cleaning liquid syringe is provided. The cleaning liquid syringe comprises a liquid suction port and a liquid discharge port. The liquid suction port is connected to a liquid storage barrel for storing the cleaning liquid, and the liquid discharge port is connected to a nasogastric feeding tube. Thus, the nasogastric feeding tube can be flushed at various time points, thereby solving the problem that the flushing operation in the existing nasogastric feeding process is troublesome and laborious, and will increase the pain of the patient.

[0008] As a preferred technical solution of the utility model, a one-way valve is provided at both the suction port and the liquid outlet. The one-way valve at the suction port and the one-way valve at the liquid outlet have opposite flow directions. When the cleaning liquid syringe rod is pulled and pushed, the cleaning liquid can be sucked in from the suction port. When the cleaning liquid syringe push rod is pushed, the cleaning liquid is pushed out from the liquid outlet to flush the nasogastric tube.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In the description of the present invention, it should be understood that terms such as "at", "upper", "lower", "opposite", "top", "bottom", "peripheral", "inside", and "surface" indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0024] During nasogastric feeding, the nasogastric tube usually needs to be left in the patient's nasal cavity and esophagus for a period of time. The indwelling feeding catheter is long, and floccules are easily attached to the tube wall, causing the catheter to be blocked. In addition, the lumen of the nasogastric tube is thin, and the incidence of tube blockage is high when infusing high-concentration nutrient solution. Therefore, it is necessary to flush the tube before, during, and after the nasogastric feeding operation, which is troublesome and laborious. At present, a nasogastric feeding syringe is commonly used in clinical practice to extract flushing fluid to flush the nasogastric feeding tube. If the tube is blocked, it is necessary to connect a needle to suck cola or sodium bicarbonate, urokinase drugs to flush the tube, which causes a large clinical workload. Moreover, contamination is easily caused by improper personal operation during the flushing process, and replacing a new nasogastric feeding tube or connecting a new flushing needle will increase the patient's pain. Based on this, the present embodiment provides a nasogastric feeding device for postoperative rehabilitation. The nasogastric feeding device has the advantages of simple and convenient operation.

[0025] See also Figure 1 and Figure 2 As shown, the nasogastric feeding device for postoperative rehabilitation provided in this embodiment includes a nutrient solution syringe 1, a cleaning solution syringe 2 and a nasogastric feeding tube 4.

[0026] See also Figure 3 As shown, one end of the cleaning liquid injector 2 is provided with two through ports, including a liquid suction port 201 and a liquid outlet port 202. The nutrient solution injector 1 is a common injector having one through port.

[0027] The liquid suction port 201 is connected to a liquid storage barrel 6 via a liquid suction tube 5. The liquid storage barrel 6 stores a cleaning liquid for flushing the nasogastric tube. The cleaning liquid can be pure water.

[0028] The length of the pipette 5 should not be too long, so as to avoid the cleaning liquid injector 2 having to suck out a large amount of air in the pipe before extracting the cleaning liquid.

[0029] The liquid outlets 202 of the nutrient solution syringe 1 and the cleaning solution syringe 2 are connected to the nasogastric tube 4 through the three-way connector 3. Specifically, the three-way connector 3 includes a first feed interface 301, a second feed interface 302 and a discharge port, the nutrient solution syringe 1 is connected to the first feed interface 301, the liquid outlet of the cleaning solution syringe 2 is connected to the second feed interface 302, and one end of the nasogastric tube 4 is connected to the discharge port of the three-way connector 3.

[0030] In a preferred implementation of this embodiment, both the liquid suction port 201 and the liquid outlet 202 are provided with a one-way valve, wherein the one-way valve at the liquid suction port 201 and the one-way valve at the liquid outlet 202 have opposite flow directions. The one-way valve at the liquid suction port 201 can only allow the cleaning liquid to flow into the cleaning liquid injector 2, while the one-way valve at the liquid outlet 202 can only allow the cleaning liquid to flow out of the cleaning liquid injector 2.

[0031] When in use, first insert the nasogastric tube 4 into the patient's body, and then connect its exposed end to the discharge port of the three-way connector 3. Next, use the pipette 5 to connect the liquid storage barrel 6 to the suction port 201 of the cleaning liquid syringe 2. Subsequently, push and pull the push rod of the cleaning liquid syringe 2 several times to extract the air in the pipette 5, and extract a small amount of cleaning liquid to flush the cleaning liquid syringe 2. When the air in the pipette 5 is exhausted, connect the liquid outlet 202 of the cleaning liquid syringe 2 to the second feed interface 302 of the three-way connector 3.

[0032] Before the nasogastric feeding operation, push and pull the push rod of the cleaning liquid syringe 2, extract cleaning liquid to pre-rinse the nasogastric feeding tube 4. When performing the nasogastric feeding operation, the nutrient solution syringe 1 extracts a certain amount of nutrient solution, and then connects the nutrient solution syringe 1 to the first feed interface 301 of the three-way connector 3, and pushes the push rod of the nutrient solution syringe 1, and the nutrient solution can be injected into the patient's body through the nasogastric feeding tube 4. In this process, due to the restriction of the one-way valve at the liquid outlet 202, the nutrient solution will not flow into the cleaning liquid syringe 2. After the nasogastric feeding is completed, the cleaning liquid syringe 2 can be used to extract cleaning liquid to rinse the nasogastric feeding tube 4, which is easy to operate. And the cleaning liquid syringe 2 does not need to be disassembled during the retention process of the entire nasogastric feeding tube 4, reducing the pain of the patient.

[0033] In a preferred implementation of this embodiment, a port plug is provided at the first feed interface 301. When the nasogastric feeding operation is completed, the port plug is inserted to prevent the tube mouth from being contaminated. At the same time, the port plug can prevent the cleaning liquid from leaking from the first feed interface 301 during the flushing of the nasogastric feeding tube by the cleaning liquid syringe 2. Of course, a port plug can also be provided at the second feed interface 302. When the cleaning liquid syringe 2 needs to be disassembled, the second feed interface 302 can be blocked to prevent contamination.

[0034] In a preferred implementation of this embodiment, scales are provided on the circumference of the nutrient solution syringe 1 and the cleaning solution syringe 2. The scale of the nutrient solution syringe 1 can ensure quantitative feeding of the nutrient solution. The scale of the cleaning solution syringe 2 can control the amount of cleaning solution used each time, which can ensure the flushing effect and achieve the purpose of saving cleaning solution at the same time, and is easy to use.
