Description

Technical Field

[0001] This utility model relates to daily necessities, and more particularly to medical devices, especially a gastrointestinal decompression device specifically for infants and young children. Background Technology

[0002] Gastrointestinal decompression involves inserting a gastric tube through the mouth or nose using negative pressure suction or siphon principles to remove gas and fluid accumulated in the gastrointestinal tract. Generally, continuous gastrointestinal decompression after surgery, with timely removal of gas and stomach contents, reduces pressure, alleviates abdominal distension, and promotes the recovery of digestive function. However, some studies have shown that continuous gastrointestinal decompression has several limitations, and its use does not necessarily reduce the incidence of postoperative complications.

[0003] Natural drainage without negative pressure can promote the natural recovery of gastrointestinal function. However, if adult non-negative pressure drainage devices, such as disposable drainage bags, are used, the airtightness of the drainage bag can easily affect the expulsion of gas from the infant's stomach, hindering breathing and increasing the risk of aspiration. Infants' indwelling gastric tubes are smaller in diameter and shallower in insertion than adults'. If adult continuous gastrointestinal decompression devices, such as disposable negative pressure drainage devices or negative pressure bulbs, are used, the gastric tube is prone to dislodgement due to improper placement or difficulty in securing the suction device. Currently, disposable PE gloves are often used clinically to collect gastric fluid by tying a knot at the end of the infant's gastric tube. However, the knot cannot be tightly connected to the end of the tube, resulting in frequent leakage of gastric fluid onto the child's sheets or clothing. This is detrimental to maintaining cleanliness and accurate measurement of the child's clothing and sheets, significantly impacting hospital infection control and clinical observation. Infant gastric fluid drainage sometimes requires natural drainage and sometimes negative pressure drainage; currently, there is a lack of gastric fluid drainage devices that can switch between natural and negative pressure drainage methods. Summary of the Invention

[0004] The purpose of this utility model is to provide a gastrointestinal decompression device specifically for infants and young children. This gastrointestinal decompression device specifically for infants and young children aims to solve the technical problem of the lack of gastrointestinal decompression devices in the prior art that can switch between natural drainage and negative pressure drainage modes.

[0005] This utility model discloses a gastrointestinal decompression device specifically for infants and young children, comprising a housing, a gastric tube interface at one end of the housing with a flow stop clamp, a drain port, a one-way vent valve, and a negative pressure suction port at the other end of the housing, a drain port cover, a one-way vent valve with a vent cover, a suction port cover, and graduation lines on the side wall of the housing.

[0006] Furthermore, a weight-adding silicone layer is provided at the bottom of the housing.

[0007] Furthermore, the shell is cylindrical and made of PVC material.

[0008] Furthermore, the liquid outlet is located at the bottom of the housing, while the one-way exhaust valve and the negative pressure suction port are located at the top of the housing.

[0009] Compared with existing technologies, this invention offers positive and significant advantages. It supports both natural drainage and negative pressure drainage for gastrointestinal decompression, allowing for quick switching between the two methods without the need for additional replacement of the gastric fluid collection device. For natural drainage, open the vent valve cover, close the suction port cover and the drain cover, and connect the infant-specific gastric tube to the gastric tube interface. The gastric tube interface matches the inner diameter of the infant-specific gastric tube for a tight connection. The gastric tube introduces gastric contents and gas into the container, and the gas is discharged through the one-way vent valve, preventing aspiration, nosocomial infections, or other adverse consequences due to poor drainage or leakage. If the child's condition changes and negative pressure drainage is required, close the drain cover and vent valve cover, open the suction port cover, and connect the negative pressure suction port to the suction tube of the negative pressure aspirator to achieve negative pressure drainage. The weight-adding silicone layer lowers the center of gravity (similar to the principle of a roly-poly toy), increasing friction with the bed surface, making it easier to place the shell on the child's bed and preventing displacement. Closing the stop clip allows the cylindrical casing to stand upright, and the graduations facilitate accurate measurement. The gastric tube connector is compatible with the inner diameter of infant-specific gastric tubes, ensuring a tight connection and preventing loosening. Attached Figure Description

[0011] The present invention will be further described below with reference to embodiments, but the present invention is not limited to these embodiments. Any similar structures and similar variations of the present invention should be included in the protection scope of the present invention.

[0012] like Figure 1 As shown, this utility model discloses a gastrointestinal decompression device for infants and young children, comprising a housing 1. One end of the housing 1 is provided with a gastric tube interface 2, and the gastric tube interface 2 is provided with a flow stop clamp 3. The other end of the housing 1 is provided with a liquid outlet 4, a one-way exhaust valve 5, and a negative pressure suction port 6. The liquid outlet 4 is provided with a liquid outlet cover 7. The one-way exhaust valve 5 has a one-way flow direction from inside the housing 1 to outside the housing 1, and the one-way exhaust valve 5 is provided with an exhaust valve cover 8. The negative pressure suction port 6 is provided with a suction port cover 9. The side wall of the housing 1 is provided with scale lines 10.

[0013] Furthermore, a weight-adding silicone layer 11 is provided at the bottom of the housing 1.

[0014] Furthermore, the housing 1 is cylindrical and made of PVC material.

[0015] Furthermore, the liquid outlet 4 is located at the bottom of the housing 1, and the one-way exhaust valve 5 and the negative pressure suction port 6 are located at the top of the housing 1.

[0016] Specifically, the flow stop clamp 3, one-way exhaust valve 5, weight-adding silicone layer 11, PVC material, etc. in this embodiment all adopt well-known solutions in the prior art, which are already known to those skilled in the art, and will not be described in detail here.

[0017] The working principle of this embodiment:

[0018] 1. This utility model supports two gastrointestinal decompression methods: natural drainage and negative pressure drainage. The two methods can be quickly switched without the need to replace the gastric fluid collection device. For natural drainage, open the vent valve cover 8, close the suction port cover 9 and the drain cover 7, and connect the infant-specific gastric tube to the gastric tube interface 2. The gastric tube interface 2 matches the inner diameter of the infant-specific gastric tube for a tight connection. The gastric tube introduces gastric contents and gas into the container, and the gas is discharged through the one-way vent valve 5 to prevent aspiration, nosocomial infection, or other adverse consequences due to poor drainage or leakage. If the child's condition changes and negative pressure drainage is required, close the drain cover 7 and the vent valve cover 8, open the suction port cover 9, and connect the negative pressure suction port 6 to the suction tube of the negative pressure aspirator to achieve negative pressure drainage.

[0019] 2. The weight-adding silicone layer 11 can lower the center of gravity (similar to the principle of a roly-poly toy), increase the friction between the shell and the bed surface, making it easier for the shell 1 to be placed on the child's bed and less likely to shift.

[0020] 3. Closing the flow stop clamp 3 allows the cylindrical shell 1 to stand upright, making it easy to accurately measure the scale line 10.

[0021] 4. Gastric tube interface 2 is compatible with the inner diameter of infant-specific gastric tubes, ensuring a tight connection and preventing loosening.

[0022] 5. When it is necessary to collect a gastric fluid sample or gastric fluid collected in the pouring device, open the pouring port cover 7 and pour the gastric fluid out from the pouring port 4.
