Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a gastric tube. Background Technology

[0002] A gastric tube is a flexible medical catheter inserted into the stomach or duodenum through the nose or mouth for diagnostic or therapeutic purposes. Its main functions include gastrointestinal decompression, enteral nutritional support, drug delivery, gastric lavage, and gastric fluid sampling and analysis; it is a commonly used basic medical tool in clinical practice.

[0003] However, in actual use, the existing gastric tubes use double connectors with interlocking ends. When feeding through a nasogastric tube, the repeated connection of one connector to the syringe can easily cause the other connector to loosen, leading to gastric reflux and other sealing problems. Therefore, this utility model proposes a gastric tube as a further improvement. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a gastric tube to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a gastric tube, comprising: a balanced pressure connector for nasogastric feeding, a gastric tube body, and a drain clamp;

[0006] The main body of the gastric tube includes: a T-shaped three-way tube, an external indwelling tube, and an internal indwelling tube. The internal indwelling tube is fixedly connected to the external indwelling tube through the T-shaped three-way tube. The T-shaped three-way tube is provided with a negative pressure interface for gastrointestinal decompression.

[0007] The pressure-balancing connector is fixedly installed at the end of the external indwelling pipe away from the T-shaped tee pipe;

[0008] The flow stop clamp is movably sleeved on the external indwelling tube.

[0009] Furthermore, the two openings of the T-shaped tee that do not change the flow direction are respectively configured as a first straight opening and a second straight opening, and the opening of the T-shaped tee that changes the flow direction is configured as a side opening.

[0010] The first straight opening and the second straight opening are fixedly connected to one end of the internal indwelling tube and one end of the external indwelling tube, respectively, and the negative pressure interface is installed on the side opening.

[0011] Furthermore, the length of the internal indwelling tube is set in the range of 65-100cm.

[0012] Furthermore, the length of the external indwelling tube is set to be no less than 15cm.

[0013] Furthermore, the length of the main body of the gastric tube is set to be no less than 115cm.

[0014] Furthermore, a scale is provided on the main body of the gastric tube.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] Compared with existing technologies, the use of a flow-stop clamp effectively ensures the airtightness of the gastric tube body, preventing breakage and cracks caused by frequent folding of the gastric tube body. The T-shaped three-way connector allows for separate placement of the negative pressure interface for gastrointestinal decompression and the balanced pressure connector for nasogastric feeding. This allows for direct opening of the flow-stop clamp to aspirate gastric contents from the balanced pressure connector without disconnecting the negative pressure interface. Therefore, this separate placement, compared to a simple Y-shaped gastric tube, avoids food residue retention and eliminates the need to rinse the interface with warm water after nasogastric feeding. The use of a graduated scale allows for control of the inserted length of the gastric tube body, achieving the desired effect and eliminating the need to check whether the gastric tube body is in the stomach before nasogastric feeding.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] As attached Figure 1 and attached Figure 2 The gastric tube shown includes: a balanced pressure connector 1 for nasogastric feeding, a gastric tube body 2, and a drain clamp 3;

[0028] The main body 2 of the gastric tube includes: a T-shaped three-way tube 21, an external indwelling tube 22 and an internal indwelling tube 23. The internal indwelling tube 23 is fixedly connected to the external indwelling tube 22 through the T-shaped three-way tube 21. The T-shaped three-way tube 21 is provided with a negative pressure port 4 for gastrointestinal decompression.

[0029] The pressure-balancing connector 1 is fixedly installed at the end of the external indwelling pipe 22 away from the T-shaped tee pipe 21;

[0030] The flow stop clamp 3 is movably connected to the external indwelling tube 22.

[0031] The balanced pressure connector 1 is connected to the syringe to enable nasogastric feeding; the balanced pressure connector 1 can be 4cm in length, and if the balanced pressure connector 1 is connected to the syringe nipple, the inner diameter is set to 0.2cm and the outer diameter is set to 0.5cm.

[0032] Among them, the balanced pressure connector 1 can also solve the problem of back bending during nasogastric feeding. The balanced pressure connector 1 is installed in a spiral manner at one end of the external indwelling tube 22 away from the T-shaped three-way tube 21; the other end of the balanced pressure connector 1 can correspond to the gastrointestinal nutrition infusion tube connector.

[0033] The use of the anti-flow clip 3 eliminates the need to fold the main body 2 of the gastric tube back, thus eliminating the need for gauze wrapping; effectively ensuring the airtightness of the main body 2 of the gastric tube; and preventing breakage and cracks caused by frequent folding of the main body 2 of the gastric tube.

[0034] Among them, the inner diameter of the negative pressure interface 4 corresponding to the gastrointestinal decompression negative pressure suction plate interface is 0.5cm; and the negative pressure interface 4 is preferably a heparin cap interface.

[0035] In a preferred embodiment, as shown in the appendix Figure 1 and attached Figure 2 As shown, the two openings of the T-shaped tee pipe 21 that do not change the flow direction are respectively set as a first straight opening A and a second straight opening B, and the opening of the T-shaped tee pipe 21 that changes the flow direction is set as a side opening C.

[0036] The first straight opening A and the second straight opening B are fixedly connected to one end of the internal indwelling tube 23 and one end of the external indwelling tube 22, respectively, and the negative pressure interface 4 is installed on the side opening C.

[0037] Since the negative pressure interface 4 and the balanced pressure connector 1 used for nasogastric feeding are placed separately, if it is necessary to quickly aspirate the contents of the stomach, the first straight opening A and the second straight opening B of the T-shaped three-way tube 21 can be used without changing the flow direction, and the stop clamp 3 can be opened directly to extract from the end of the balanced pressure connector 1 without disconnecting the negative pressure interface 4. Therefore, placing them separately can avoid food residue from being left behind compared to a simple Y-shaped gastric tube, and saves the need to rinse the other end of the interface with warm water after nasogastric feeding.

[0038] In a preferred embodiment, as shown in the appendix Figure 1 and attached Figure 2 As shown, the length of the internal indwelling tube 23 is set in the range of 65-100cm.

[0039] The length of the internal indwelling tube 23 is set to 100cm;

[0040] In a preferred embodiment, as shown in the appendix Figure 1 and attached Figure 2 As shown, the length of the external indwelling tube 22 is set to be no less than 15cm.

[0041] The length of the external indwelling tube 22 is set at 15cm;

[0042] In a preferred embodiment, as shown in the appendix Figure 1 and attached Figure 2 As shown, the length of the main body 2 of the gastric tube is set to be no less than 115cm.

[0043] In a preferred embodiment, as shown in the appendix Figure 1 and attached Figure 2 As shown, a scale is provided on the main body 2 of the gastric tube.

[0044] Since the distance inside the stomach varies from patient to patient, i.e. the length of the gastric tube inserted varies, the distance from the hairline to the xiphoid process of the sternum is often used as a reference in clinical practice. If the hairline is not obvious, the distance from the tip of the nose through the earlobe to the xiphoid process can be used for measurement. If gastrointestinal decompression is being performed, the distance from the center of the eyebrows to the navel can be used to determine the length of the gastric tube inserted.

[0045] Therefore, this invention uses a ruler as an aid to control the length of the inserted gastric tube;

[0046] Depending on the use of the gastric tube, if nasogastric feeding is performed, the insertion length for adults is generally 45-55cm; if gastrointestinal decompression is performed, the insertion length for adults is generally around 55-65cm.

[0047] Therefore, this utility model has a scale on the main body 2 of the gastric tube, which can be used to control the length of the inserted gastric tube body 2, thereby achieving the expected effect and avoiding the need to check whether the main body 2 of the gastric tube is in the stomach before nasogastric feeding.
