Technical Field
[0001] The utility model provides a nasogastric feeding tube pressure detection device, which relates to the technical field of nasogastric feeding. Background Art
[0002] Nasogastric feeding is a method in which a gastric tube is artificially placed into the esophagus through the nasal cavity under special circumstances. The food is first ground into a paste using a grinder, and a large syringe is used to connect the large feeding port under the gastric tube connector. After the connection is secure, the push rod piston is manually pressurized to pump water and food into the patient's stomach, helping patients who cannot swallow independently to provide water and food and maintain their body metabolism, weight and nutrition.
[0003] When performing nasogastric feeding, it is necessary to assess the gastrointestinal and esophageal pressure conditions to predict the risk of gastrointestinal reflux, provide early clinical intervention, and reduce reflux aspiration. When using a nasogastric tube for feeding, it is necessary to perform pressure testing on the esophagus and gastrointestinal tract in advance, and use X-rays to identify abnormal pressure points so that treatment can be targeted at the abnormal pressure areas. Existing nasogastric tubes generally do not have pressure detection and positioning functions, and cannot reflect changes and abnormalities in gastrointestinal pressure during feeding.
[0004] Therefore, it is necessary to provide a nasogastric tube pressure detection device that can detect and locate gastrointestinal pressure. Utility Model Content

DETAILED DESCRIPTION
[0027] The present invention will be further described below with reference to specific embodiments. It should be noted that, unless otherwise specified or limited, terms such as "dispose," "install," "connect," and "connect" should be understood in a broad sense. For example, "connect" may refer to a fixed connection, a detachable connection, or an integral connection; it may refer to a mechanical connection or an electrical connection; it may refer to a direct connection or an indirect connection through an intermediate medium; or it may refer to internal communication between two components. A person skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on the specific circumstances.
[0028] Example 1: A nasogastric tube pressure detection device, see Figure 1-Figure 3 As shown, it includes a first flip cover 1, a first hose 2, a branch pipe 3, a second flip cover 4 and a second hose 5. The first hose 2 is connected to the branch pipe 3. The side of the first hose 2 is fixedly connected to the first flip cover 1. The first flip cover 1 is embedded in the opening of the first hose 2. The side of the branch pipe 3 is fixedly connected to the second flip cover 4. The second flip cover 4 is embedded in the opening of the branch pipe 3. The end of the first hose 2 away from the branch pipe 3 is connected to the second hose 5. The second hose 5 can be detached from the first hose 2. The second hose 5 is a food-grade silicone tube and will not cause harm to the human body after entering the human body. It also includes an insulating tube 6, a first electrode 7, a second electrode 701, a first sensor chip 8, a second sensor chip 9, and a first electrode 702. The second hose 5 is provided with a mounting shell 10, a positioning chip 11, and four insulating tubes 6 are sleeved on the second hose 5. The first electrode 7 and the second electrode 701 are fixedly connected on both sides of the insulating tube 6. The first sensing chip 8 is installed in the first electrode 7, and the second sensing chip 801 is installed in the second electrode 701. The first sensing chip 8 and the second sensing chip 801 are used to sense gastrointestinal pressure. One end of the second hose 5 is sleeved with a mounting shell 10, and a positioning chip 11 for collecting data is installed in the mounting shell 10. The positioning chip 11 and each first sensing chip 8 and second sensing chip 801 are fixedly connected with a wire 9.
[0029] When nasogastric feeding is required, the second hose 5 is passed from the patient's nasal cavity into the esophagus and into the stomach. The first flap 1 is then pulled out from the first hose 2. Water and food are injected into the first hose 2 through a syringe. The food and water pass through the first hose 2 into the second hose 5 and finally into the patient's stomach. When injecting food into the first hose 2, if the injection is too fast and causes blockage, there is no need to pull out the syringe. The second flap 4 is pulled out from the branch pipe 3 and a tool is inserted from the branch pipe 3 to clear the blockage of the first hose 2. When the second hose 5 is placed in the patient's gastrointestinal tract, When the gastrointestinal tract generates a certain pressure on the first electrode plate 7 and the second electrode plate 701, the first sensing chip 8 and the second sensing chip 801 will detect the corresponding pressure data and transmit the pressure data to the positioning chip 11 through the wire 9. The positioning chip 11 sends the pressure data and the pressure abnormality point feedback to the monitor outside the patient's body. According to the pressure abnormality point, the pressure abnormality point is accurately located in combination with X-ray visualization detection, and the cause of the abnormality is found to facilitate subsequent treatment. In this way, the abnormal pressure points in the patient's gastrointestinal tract and esophagus are located and the pressure situation is evaluated.
[0030] Example 2: Based on Example 1, refer to Figure 4 and Figure 5 As shown, it also includes a mounting tube 12 sleeved and installed on the end of the first hose 2 away from the branch pipe 3, and a connecting tube 13 sleeved and installed on one end of the second hose 5, and the connecting tube 13 is threadedly connected to the mounting tube 12.
[0031] When the second hose 5 needs to be replaced, the first hose 2 and the second hose 5 are rotated to disconnect the mounting tube 12 from the connecting tube 13, and the second hose 5 can be replaced. The first hose 2 and the second hose 5 are connected by docking the mounting tube 12 with the connecting tube 13 and rotating the first hose 2 and the second hose 5 in the opposite direction to connect the mounting tube 12 with the connecting tube 13.
[0032] See Figure 6 and Figure 7 As shown, it also includes a mounting sleeve 14 mounted on the first hose 2 by bonding, and an elastic rope 15 is fixedly connected to the mounting sleeve 14 by a knotted tether. The elastic rope 15 is penetrated by an adjusting block 16 for adjusting the tightness, and a clamping plate 17 for clamping the elastic rope 15 is slidably provided in the adjusting block 16. A first elastic member 18 is fixedly connected between the adjusting block 16 and the clamping plate 17 by welding, and the first elastic member 18 pushes the clamping plate 17 to slide toward the outside of the adjusting block 16.
[0033] When the patient uses a nasogastric tube, the elastic rope 15 can be put on the neck to prevent the first hose 2 and the second hose 5 from shifting in position when the patient moves slightly. When the tightness of the elastic rope 15 needs to be adjusted, the clamping plate 17 is first slid and pressed into the adjusting block 16. At this time, the first elastic member 18 is compressed and deformed by the force. Then, the elastic rope 15 can be pulled through the adjusting block 16 to adjust the tightness of the elastic rope 15. After the adjustment is completed, the clamping plate 17 is released. At this time, the first elastic member 18 pushes the clamping plate 17 to slide back to its original position, so that the clamping plate 17 and the adjusting block 16 can clamp the elastic rope 15 together.
[0034] See Figure 8 and Figure 9 As shown, it also includes a guide plate 19 slidably arranged on the first hose 2. The length of the guide plate 19 is greater than the length of the slide groove on the first hose 2, so that the first hose 2 can remain sealed and food and water will not leak. A second elastic member 20 is fixedly connected between the guide plate 19 and the first hose 2. The second elastic member 20 pushes the guide plate 19 to slide toward the side close to the first flip cover 1. A first sealing ring 21 is slidably provided in the first hose 2. The first sealing ring 21 is fixedly connected to the guide plate 19 by bonding.
[0035] When food and water need to be injected into the first hose 2, the first flip cover 1 is pulled out. At this time, the second elastic member 20 pushes the guide plate 19 to slide toward the opening of the first hose 2, so that the syringe needle can pierce the first sealing ring 21 to inject food and water into the first hose 2. After the injection is completed, the guide plate 19 drives the first sealing ring 21 to slide into the inside of the first hose 2. At this time, the second elastic member 20 is compressed and deformed by the force, and then the first flip cover 1 is inserted into the first hose 2, so that the first flip cover 1 limits and protects the first sealing ring 21.
[0036] See Figure 8 As shown, the first flip cover 1 and the second flip cover 4 are both sleeved with a second sealing ring 22. The second sealing ring 22 increases the tightness of the fit between the first flip cover 1 and the first hose 2, and the second flip cover 4 and the second hose 5, to prevent food and water from overflowing and leaking out.
[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
