Multifunctional stomach irrigator

Abstract

The invention relates to a multifunctional stomach irrigator, which is characterized in that a design of a Y-shaped joint and a liquid pouring funnel is adopted, and a suction function and a gastric lavage function are combined. One-way valves different in directions are respectively arranged at the front end and the rear end of an air bag, and thus, persistent pressurization can be realized, and backflow can be avoided; through three specially arranged regulating tubes, a proper pressure range can be reached; by adopting a drainage bag with a drawing-type outlet, liquid can conveniently outflows. The multifunctional stomach irrigator has the effects that the liquid backflow cannot be easily caused during operation, and negative pressure in a negative-pressure system can be continuously increased to enhance suction; through a special pressure control device, the negative pressure can be controlled to be within a proper range; meanwhile, the multifunctional stomach irrigator is simple in operation and low in manufacturing cost, has good economic benefit, and is energy-saving and free of noise, not limited by environmental conditions, used in a one-to-one manner, capable of avoiding cross infection, and is safe and reliable.

Description

Technical field [0001] The invention involves the field of medical devices, especially a multifunctional gastric lavage. Background technique [0002] At present, the attractors or gastroders equipped by major hospitals require external equipment such as power supply. It is inconvenient to carry, high costs, and complex operations and not suitable for out -of -hospital use.And the existing simple attraction or gastrochemicals involved in the gastric lavage mainly uses the simple squeezing of ear -washing or leather pins to achieve the purpose of negative pressure attraction, but often the following problems are easy to exist: (1)) Residual liquids are easily squeezed back to the patient's similar products when they are attracted to the positive pressure caused by squeezing the ear washing or the leather sac when they are attracted.Inside the body.(2) Proper negative pressure causes poor attractive effects Clinically attractors during sputum-absorbing and other negative pressure r...

Problems solved by technology

[0002]At present, the aspirators or gastric lavage devices equipped in major hospitals all need external equipment such as power supplies, which are inconvenient to carry, high in cost, complicated in operation and not suitable for out-of-hospital use. use

However, the negative pressure system involved in the existing simple suction device or gastric lavage device used outside the hospital mainly uses simple extrusion of the ear wash ball or skin bag to achieve the purpose of negative pressure suction, but it is often easy to have the following problems: (1) ) Residual liquid is easy to be squeezed back into the patient's body. Similar products often squeeze the residual liquid in the suction tube and other parts back to the patient due to the positive pressure generated by squeezing the ear wash ball or skin bag during continuous suction. in the body

(2) Insufficient negative pressure is prone to lead to poor suction effect. The negative pressure of clinical aspirator requires adults to be controlled at about 0.04-0.05 Mpa during sputum suction and other operations, and the negative pressure of gastric lavage device for adults is required to be controlled at 0.03-0.04 during gastric lavage. About Mpa

Due to squeezing the elastic bladder, just extruding the air in the elastic bladder cannot completely squeeze out the air in the entire negative pressure system, so the negative pressure formed is often less than a standard atmospheric pressure. As the liquid enters the negative pressure system, the negative pressure drops, and when the patient's sputum, vomit or gastric lavage fluid is viscous, it is more likely to cause poor suction effect due to insufficient negative pressure

(3) Some patients may experience unnecessary injuries due to excessive negative pressure At present, the existing simple suction devices or gastric lavage devices used outside the hospital are often not equipped with pressure control equipment, especially when the volume of the elastic skin bag is too large , the negative pressure caused by squeezing the elastic skin bag may be too strong, and it is easy to cause unnecessary damage to the patient due to too strong negative pressure

(4) Suction or gastric lavage effect with single function The existing simple suction device or gastric lavage device used outside the hospital only has a single function of suction or gastric lavage, but does not combine the functions of the two

The present invention overcomes the defects of the existing simple suction device or gastric lavage device in the market: (1) During the suction process of the existing invention, part of the air may enter the negative pressure system with the liquid or the negative pressure may be caused by the viscous sputum Insufficient, and the present invention can achieve continuous pressurization through a continuous negative pressure mechanism; (2) The existing invention is prone to residual fluid reflux during multiple consecutive suctions, but the present invention can avoid this by being provided with a one-way valve Reflux; (3) Existing inventions cannot safely and effectively control negative pressure
