Description

Technical Field

[0001] The utility model relates to a gastric effusion extraction device, in particular to a gastric effusion extraction device capable of reducing gastric fluid reflux. Background Art

[0002] Gastric tumor is a common disease of the digestive system, which can be divided into malignant and benign. In clinical practice, gastric tumor needs to be removed, and gastric juice needs to be extracted during the removal. The doctor inserts a steamed and sterilized gastric tube into the stomach through the nose or mouth. A depth of 50-55 cm can reach the greater curvature mucus pool of the stomach. Then a 50 ml syringe is connected to the outer end of the gastric tube to suck out the gastric juice, or a negative pressure pump is used for continuous suction. After it is full, it is injected into the container, and then the pipe is connected to continue suction. During the collection process, the patient needs to change body position, that is, change between supine, side, prone and sitting positions, and try to suck out the gastric fluid as much as possible. After the tube is removed, the amount of gastric fluid extracted is recorded. Because the effusion needs to be transferred through syringes and containers many times, it is impossible to continuously aspirate the effusion, and contamination problems are inevitable during the transfer of the effusion.

[0003] The utility model patent with the publication number of CN217908460U discloses a novel gastric juice recovery and storage device, including a reversing valve and a gastric juice container, wherein the first interface of the reversing valve is connected to a gastric tube, the second interface of the reversing valve is connected to a syringe, the third interface of the reversing valve is connected to a first end of a straw, and the second end of the straw reaches the bottom of the container, and the syringe is used to extract gastric juice from the gastric juice container through the reversing valve, and then inject it back into the gastric tube. The problem of inconvenience and easy contamination of gastric juice extraction and reinjection is solved. However, in the actual use of the gastric tube intubation process, it is necessary to perform a tube closing operation, which is generally performed by pinching the tube with fingers. In order to achieve a good tube closing effect, the fingers pinch the tube more forcefully, and obvious folds will be formed at the pinching place, which is easy to cause hard damage at the pinching place and cannot be completely restored; and when winding the gastric tube, the gastric tube is usually directly wrapped around the hand, and the bending operation at an extreme distance is prone to tube wall closure, resulting in failure of gastric juice extraction, causing certain troubles to the nursing staff. Summary of the invention

[0004] The purpose of the utility model is to overcome the defects in the prior art and provide a fluid extraction device for reducing gastric fluid reflux, which is easy to use, avoids damage to the gastric tube when closing the gastric tube, reduces the occurrence of unnecessary tube inner wall closure due to natural tube bending, is simple to operate and can be reused multiple times.

[0006] The limiting cover is provided with a pipeline clamping mechanism capable of closing the gastric tube; the pipeline clamping mechanism includes a spring, a limiting channel and a pressure rod, and the limiting channel is connected with the pipeline channel; a spring installation cavity for placing a spring is provided in the limiting channel, the upper end of the pressure rod is located outside the limiting channel, the pressure rod passes through the limiting channel and the spring, and a pressure block is provided at the lower end of the pressure rod, the pressure block is located below the spring installation cavity, and a pressure ring for resisting the spring is fixed on the pressure rod, the pressure ring is limited in the spring installation cavity and is located at the upper end of the spring; when the pressure rod is pressed down, the gastric tube is pressed and closed by the pressure block.

[0007] The inner slide is a semicircular tube-shaped slide with an open top.

[0008] The bottom surface of the pressing block is an arc surface matched with the inner slideway, and when the pressing rod is pressed down, the bottom surface of the pressing block contacts the stomach tube.

[0009] The axis of the limiting channel is perpendicular to the axis of the pipeline channel.

[0010] A contact head is provided at the front end of the stomach tube. The cross section of the contact head is in an arc shape. A silicone film is provided on the surface of the contact head.

[0011] The tail end of the stomach tube is provided with a connector for connecting an electric suction device.

[0012] A hanging hole is provided on the handle.

[0013] A hand-holding ring is provided on one side of the handle.

[0014] A pressing block is arranged at the upper end of the pressing rod.

[0015] The beneficial effects of the utility model are: simple operation and repeated use. The front half of the inner slide is arc-shaped and the rear half is straight-line, which can facilitate users to bend the tube according to needs and prevent the possibility of closure of the inner wall of the gastric tube and failure of guiding the effusion due to natural bending and folding of the tube.

[0016] The gastric tube is closed by the tube clamping mechanism, and the tube clamping mechanism and the inner slideway are only involved in the operation of sealing and bending the gastric tube, and are not involved in the operation of guiding the effusion. Therefore, the utility model can meet the needs of multiple repeated uses, reduce the need for nursing staff to manually pinch the tube for closing operations, and is convenient for users to use.

[0017] The cross section of the contact head is in an arc shape to form a semi-open shape, which can increase the adsorption area of ​​the gastric tube to gastric juice. At the same time, a silicone film is provided on the surface of the contact head. Through the biocompatibility characteristics of the silicone film, the human stomach can adapt well to the insertion of the gastric tube into the stomach, reduce the physiological phenomenon of nausea caused by tingling or foreign objects inserted into the stomach, reduce the reflux of gastric juice caused by nausea, and effectively facilitate nursing staff to guide gastric juice. The hanging hole provided on the handle satisfies the need for placement in a hanging form, which is convenient for nursing staff to use. BRIEF DESCRIPTION OF THE DRAWINGS
