Novel observation tube for pediatric gastrointestinal decompression device

Abstract

The invention relates to a novel observation tube for a pediatric gastrointestinal decompression device, which comprises a body, the surface of the body is provided with scales, the top of the body isprovided with a first bayonet and a second bayonet, the first bayonet is connected with a negative pressure device through a pipeline, and the second bayonet is connected with a stomach tube throughthe pipeline; wherein a first insertion hole and a second insertion hole are formed in the body, a filter screen is arranged in the body, one end of the filter screen is fixedly connected to the innerwall of the body, the other end of the filter screen extends out of the first insertion hole, a sampling part is further arranged in the body, one end of the sampling part is fixedly connected to theinner wall of the body, and the other end of the sampling part extends out of the second insertion hole; a sealing layer is arranged at the bottom of the body, and the sealing layer can be separatedfrom the body and can also seal the bottom of the body. The novel observation tube is reasonable in structure and high in use reliability, and the scales arranged on the body facilitate observation ofthe color, quality and quantity of flow guide liquid.

Description

technical field [0001] The invention relates to medical equipment, in particular to a novel observation tube for children's gastrointestinal decompressor. Background technique [0002] Children's digestive system is immature, and the stomach capacity is small. The gastrointestinal decompressor currently used clinically is the gastrointestinal decompressor used by adults, with a large capacity; in addition, there is no clear negative pressure value on the traditional disposable negative pressure drainage device The operator cannot grasp the value of the negative pressure well during the operation. If the negative pressure is too small, the gastric contents cannot be fully drained, and the purpose of gastrointestinal decompression cannot be achieved. As the intra-abdominal pressure increases, it may cause vomiting If the negative pressure is too large, it is easy for the gastric tube to attract the gastric wall or the reduction of the tension of the gastric tube will make the ...

Problems solved by technology

[0002] Children's digestive system is immature, and the stomach capacity is small. The gastrointestinal decompressor currently used clinically is the gastrointestinal decompressor used by adults, with a large capacity; in addition, there is no clear negative pressure value on the traditional disposable negative pressure drainage device The operator cannot grasp the value of the negative pressure well during the operation. If the negative pressure is too small, the gastric contents cannot be fully drained, and the purpose of gastrointestinal decompression cannot be achieved. As the intra-abdominal pressure increases, it may cause vomiting If the negative pressure is too large, it is easy for the gastric tube to attract the gastric wall or the reduction of the tension of the gastric tube will make the gastric lumen become smaller and adhered, causing gastric mucosal damage, drainage blockage, and poor drainage. The existing gastrointestinal decompressor still exists Problems such as inconvenient placement and easy leakage, the leakage of the diversion liquid is likely to bring secondary pollution to the patient
