CN-224207142-U - Negative pressure saccule and gastrointestinal decompression drainage bag

Abstract

The utility model discloses a negative pressure balloon, which comprises a balloon body and an elastic gasket, wherein the balloon body is of a hollow structure, joints capable of communicating a liquid inlet pipe and a liquid outlet pipe are respectively arranged at two ends of the balloon body, the elastic gasket is arranged in the balloon body, and a pressing area of the balloon body is correspondingly arranged with a covering area of the elastic gasket. According to the negative pressure balloon disclosed by the utility model, the elastic gasket is arranged in the balloon body, so that the phenomenon that the balloon body is completely collapsed and cannot rebound normally due to overlarge force application of an operator can be reduced by utilizing good rebound resilience of the elastic gasket, and the normal use of the negative pressure balloon can be ensured. The utility model also discloses a gastrointestinal decompression drainage bag.

Description

Negative pressure saccule and gastrointestinal decompression drainage bag Technical Field The utility model relates to the technical field of gastrointestinal decompression drainage bags, in particular to a negative pressure balloon and a gastrointestinal decompression drainage bag. Background The gastrointestinal decompression is inserted from the oral cavity or the nasal cavity through the gastric tube, is connected with the gastrointestinal decompression device, and sucks out gas and liquid in the gastrointestinal tract by utilizing the negative pressure and siphon principle, thereby reducing the pressure in the gastrointestinal tract. Gastrointestinal decompression is one of the most basic nursing techniques used in general surgery, and is a method for leading gastric contents and qi accumulation in the gastrointestinal tract out of the body of a patient. Especially for the people with digestive tract anastomosis, the utility model can relieve the tension of the gastrointestinal tract, prevent the stomach from being excessively expanded, relieve the tension of the anastomosis, promote the healing of the anastomosis, effectively improve the gastrointestinal function of the patient, relieve the abdominal distension, improve the blood circulation of the gastrointestinal wall, promote the limit of inflammation, be beneficial to the extraction of gastric contents, accelerate the recovery progress of the gastric contents and be widely applied. The current widely used gastrointestinal decompression bag achieves the purpose of negative pressure drainage by manually extruding the negative pressure saccule, but if the extrusion force of the negative pressure saccule is too large, the negative pressure saccule can be completely collapsed and cannot rebound normally, so that the negative pressure suction cannot be normal, and gastric mucosa can be damaged to cause intragastric hemorrhage in serious cases. Therefore, how to improve the situation that the negative pressure balloon completely collapses and cannot rebound normally is a technical problem to be solved urgently by the person skilled in the art. Disclosure of utility model Accordingly, the present utility model is directed to a negative pressure balloon to improve the situation that the negative pressure balloon is completely collapsed and cannot rebound normally. Another core of the utility model is to disclose a gastrointestinal decompression drainage bag comprising the negative pressure balloon. In order to achieve the above purpose, the present utility model provides the following technical solutions: A negative pressure balloon, comprising: the balloon body is of a hollow structure, and joints capable of communicating the liquid inlet pipe and the liquid outlet pipe are respectively arranged at two ends of the balloon body; The elastic gasket is arranged in the sacculus body, and the pressing area of the sacculus body is correspondingly arranged with the covering area of the elastic gasket. Optionally, in the negative pressure balloon, the elastic gaskets are arc-shaped, and the number of the elastic gaskets at least comprises two opposite arranged elastic gaskets. Optionally, in the negative pressure balloon, the elastic pad is connected with the balloon body in a clamping manner. Optionally, in the negative pressure balloon, the elastic pad is adhesively connected with the balloon body. Optionally, in the negative pressure balloon, the elastic gasket is annular, and two ends of the elastic gasket corresponding to the liquid inlet pipe and the liquid outlet pipe are of opening structures. Optionally, in the above-described negative pressure balloon, the pressing area of the balloon body is different in color from the balloon body, and/or, The pressing area of the balloon body is provided with a preset shape or pattern. Optionally, in the negative pressure balloon, the elastic pad is a metal pad or an alloy pad or a non-metal pad. Optionally, in the negative pressure balloon, a one-way valve is arranged on at least a joint communicated with the liquid inlet pipe. Optionally, in the negative pressure balloon, the balloon body is made of a silica gel material, a rubber material or a polyurethane material. A gastrointestinal decompression drainage bag, which comprises the negative pressure saccule. According to the negative pressure balloon disclosed by the utility model, the elastic gasket is arranged in the balloon body, so that the phenomenon that the balloon body is completely collapsed and cannot rebound normally due to overlarge force application of an operator can be reduced by utilizing good rebound resilience of the elastic gasket, and the normal use of the negative pressure balloon can be ensured. The gastrointestinal decompression drainage bag disclosed by the utility model has the same technical effect as a negative pressure saccule, and is not repeated.
