Problems solved by technology

However, how to build a biphasic working structure with sufficient high / low, positive / negative pressure, and capacity is a design challenge. The biphasic working structure needs to meet clinical high pressure, high flow rate, high viscosity, rapid suction, and high discharge volume flushing Debridement, low negative pressure gastrointestinal decompression gastric lavage, low negative pressure thoracic blood recovery, autologous blood transfusion and other functions, the design is complex and difficult
It involves a series of structural elements and element combinations to build an effective rescue system, and there has been no relevant report so far

Embodiment 1

[0032] The accident happened outside the hospital, and the patient was seriously injured in many places, craniocerebral injury, mental coma, upper respiratory tract was blocked by blood and mucus, and it was extremely difficult to breathe. The inflow channel 10 of the body is connected to the standard sputum suction tube, the outflow channel 11 is connected to the collection bag, the mouth is pried open with the air circuit board, and the stretch and contraction movement function section 3 is pinched to the maximum deformation with one hand to form the maximum negative pressure per stroke, and then inserted The suction tube quickly sucks bloody sputum, and the collection bag collects vomit, purulent sputum, blood clots, soil, etc. that are blocked in the mouth. Stop after the casualty's breathing tends to be stable, and the overall operation process is completed within one minute.

Embodiment 2

[0034] The accident occurred in the operating room of a township hospital. A wounded patient with ruptured spleen and hemorrhagic shock was being rescued in the operating room. His blood pressure dropped to 40 mm Hg, and no matching blood source could be found. He was already in a state of frequent cardiac arrest. The inflow pipeline 10 is connected with the autologous blood recovery tube, and the outflow pipeline 11 is connected with the survival bag, and all connections are completed within 30 seconds. The autologous blood recovery tube is aimed at the bleeding and hemorrhage site, such as the abdominal cavity and thorax. After confirming that there is no pollution, the pump body is squeezed with a low negative pressure method to suck the blood into the lifesaving bag, and physiological saline or anticoagulant is added to the bag. That is, squeeze the pump body several times with light force, continuously suck out the blood, and then return it to the wounded person through th...

Embodiment 3

[0036] Swallowing / mistaking highly poisonous, firearm injuries, burn injuries and other wounded can easily lead to upper gastrointestinal burns and other diseases. According to the injury, you can quickly take out the gastrointestinal decompression bag containing the pump body, and put the stomach first. The intestinal decompression tube is placed into the stomach through the mouth / nasal passage, and the other end is connected to the pump body inflow channel 10, and the pump body is squeezed several times with low negative pressure to perform gastrointestinal decompression. If intermittent gastric lavage is required, connect one of the gastric tube tees to the pump body outflow channel 11, and the pump body inflow channel pipeline 10 to the flushing fluid bag; the other of the gastric tube tees is connected to the fluid storage bag for flushing. An internal circulation that flushes the stomach is formed. The flushing liquid used is neutralized by neutral / weak acidic / weak alkal...

Abstract

The invention relates to medical rescue equipment, in particular to a shuttle-shaped scale-shaped positive and negative pressure dual-phase hand pump, which is suitable for rapid suction with high negative pressure, has the function of rapid suction with high viscosity, gastrointestinal decompression function with low negative pressure, low Negative pressure chest blood recovery function and high pressure debridement and flushing function. The applicant has carried out a large number of experiments and obtained the size of the present invention, which can meet the hand shape of most medical personnel, the coordination and unity of the tension of the pump body wall and the compliance of the pump body wall, the coordination and unity of the power of the pump body and the speed per hour, and the coordination and unity of the pressure capacity and the pump body wall. The coordination and unification of the suction and discharge volume adapts to the scope of application more, improves the practicality and operability, and realizes a strong freehand operation, which can be fast or slow, the pressure can be high or low, and the flow can be more It can be less, according to the needs of the injury, the energy release can be implemented to meet the functions of high-flow, high-viscosity negative pressure sputum suction, low negative pressure gastrointestinal decompression, and autologous blood recovery; high output spray flushing and debridement functions, etc.

Description

technical field [0001] The invention relates to medical rescue equipment, in particular to a shuttle-shaped scale-shaped positive and negative pressure dual-phase hand pump, which is suitable for rapid suction with high negative pressure, has the function of rapid suction with high viscosity, gastrointestinal decompression function with low negative pressure, low Negative pressure thoracic blood recovery function and high pressure debridement and flushing function are especially suitable for clinical multi-specialty disciplines, especially for front-line first-line rescue in the hospital. Background technique [0002] Since 1990, a hand pump system invented by the author for autologous blood recovery, pressurized blood transfusion, negative pressure suction, and closed drainage was disclosed for the first time in China, and the patent number is ZL902050877. So far, no disposable plastic "pump body" device of similar form has been found in the market. However, how to build a...
