Description

Helimrick first aid machine

Technical Field

The invention relates to a first-aid device, in particular to a Helimek first-aid machine.

Background

In the process of swallowing and eating by mistake, the breathing difficulty of blocked airways of people (especially old people and children) is easily caused, so that suffocation is caused, especially some people diagnosed with Alzheimer disease, organic mental disorder of brain and Parkinson disease or patients with various body diseases mainly lie in bed, the patients can suffer from swallowing function reduction, eating or drinking choking cough due to old age, physical weakness or cerebrovascular accident and the like, the clinical dysphagia phenomenon often occurs, the life of the patients is threatened, and if the patients cannot be rescued in the first time, the death rate is very high.

When dysphagia occurs, breathing difficulty, severe cough and breathing frequency change are usually shown, the face is pale or purplish, the existing airway foreign matters mostly adopt a suction apparatus to suck oral food, the respiratory tract is unblocked, the time is long, and the rescue success rate is low.

The Helimrick first aid method is one effective first aid method, and includes applying pressure to the upper abdomen of the patient to force the upper abdomen to sink and to make the diaphragm rise suddenly and the chest pressure of the patient increase suddenly, so that the gas inside the chest cavity will be exhausted from the air passage, and the food or foreign matter in the air passage will be exhausted along the air flow to restore the smoothness of the air passage.

When a patient suffers from dysphagia, the patient needs to be rescued at the first time. However, when many patients feel dysphagia at present, the patients often cannot get the first time rescue for various reasons, and finally serious consequences are caused.

Disclosure of Invention

The invention aims to solve the problem that the patient cannot be rescued in time when the patient suffers from dysphagia, and provides a Helminek first-aid machine which can rescue the patient in the first time when the patient suffers from dysphagia and can save the life of the patient in time.

The purpose of the invention is realized by the following technical scheme: a Helmhick first aid machine comprises a pressing device, an air bag device, a respiration monitoring device and a control module, wherein two ends of the pressing device are connected with two ends of the air bag device through binding bands respectively; the pressing device comprises a motor, a cam and a push rod, wherein the cam is connected to the motor, one end of the push rod is abutted against the profile surface of the cam, the cam drives the push rod to reciprocate along the axial direction when rotating, and the other end of the push rod is provided with a pressing plate; the air bag device comprises a back air bag and an air pump, the back air bag is connected with the air pump through an air guide pipe, and a safety control valve is arranged on the air guide pipe; the respiration monitoring device, the motor and the air pump are respectively and electrically connected with the control module.

Before a patient eats, the invention is firstly sleeved on the patient, the pressing plate is aligned to the upper abdomen of the patient, the air bag on the back is attached to the back of the patient, and the respiration monitoring device is attached to the heart of the patient. When the patient eats, the respiration monitoring device can monitor the respiration of the patient in real time. When the patient takes place to choke when eating, patient's breathing can change, breathe monitoring devices and carry out the analysis to respiratory frequency, give control module with signal transmission when discovering respiratory frequency anomaly, control module control motor and air pump function, the air pump is aerifyd the back gasbag and is made the bandage be in the state of tightening, then press device reciprocates to the upper abdomen portion of patient and presses, when pressing, motor drive cam is rotatory, the cam drives the push rod and carries out reciprocating motion, the push rod drives and presses the pressing plate and reciprocate to the patient, in the pressing process, force patient's upper abdomen portion to sink, cause the diaphragm muscle to rise suddenly, patient's thorax pressure increases suddenly, the gas in the thorax just can be followed the air flue and discharged, the food or the foreign matter of card in the air flue just can be along the air current discharge like this, resume the smooth and easy of air flue. When a patient suffers from dysphagia, the patient can be rescued at the first time, precious time is won for the patient, the injury to the patient is reduced, and the success rate of rescue is improved. The back gasbag can be on the one hand to supporting patient's back, plays the guard action to the skeleton on patient's back, and on the other hand gasbag can make the bandage tighten after aerifing, makes to press the upper abdomen portion that the pressure board hug closely the patient, makes the pressing of pressing the pressure board more effective.
