Description

Hand-pressed first-aid appliance for automatic insufflation to lung

The present invention relates to a kind of hand first aid device of reviving of automatically blowing, belong to medical apparatus, the patient who is particularly suitable for suffering from cardiovascular and respiratory system disease take place suddenly heart beating stop, breathing completely without the time first aid use.

Add up according to World Health Organization (WHO), the whole world has 1,002 million peoples to die from cardiovascular and cerebrovascular disease every year approximately, the No.1 killer of the human health of being known as, moreover, also has the sickness rate height, and, stop when heart beating appears suddenly in the patient to the trend development of rejuvenation, breathe completely without situation the time should in time carry out the artificial heart-lung art of reviving.Common way is earlier the patient to be lain low on harder flat board, unbutton one's jacket make chest exposed after, be stacked in both hands and be commonly called as the pit of the stomach position, after firmly pushing five times continuously, another person then clutches the patient nostril and gives a puff to the patient in mouth-to-mouth mode, decontrol the nostril then, it is unblocked that patient nostril and mouth can freely be breathed, so, that goes round and begins again and do not stop sues and labours till the patient revives, traditional so loaded down with trivial details backwardness of first aid mode, it is big to consume one's strength, even the professional is difficult to also guarantee that its action links up, therefore matching coordinative often causes the patient to revive slowly, even happy mistake first aid opportunity, survival rate is low; Also cause taking place after contagion and the first aid easily such as sequela such as hemiplegia and class plant man.Thereby visible traditional emergency and current era forms great contrast, and necessity of further improvement is arranged.

The object of the present invention is to provide a kind of easy rational in infrastructure, simple to operate, first aid action to cooperate the harmony that closely links up, to impel the sequela after the patient can revive, eliminate contagion and first aid in the past fast.And can improve first aid success rate, the little hand-pressed first-aid appliance for automatic insufflation to lung of physical demands.

The objective of the invention is to realize by the following technical solutions, it comprises a height-adjustable frame, the device of calming the anger that links with the hand bar, the bottom links to each other with air storing duct by check valve, sucker is located at the below of the bracing frame on the device of calming the anger, air storing duct is chewed with air shut-off valve by connecing of a side and is joined, and air shut-off valve links to each other with the inlet end of mouth and nose respiratory organ on placing patient's mouth and nose respectively by flexible pipe.

The described device of calming the anger comprises a flexible air bag, has upper cover plate and base plate on it, connects a bracing frame under the upper cover plate, which is provided with the check valve that only allows the air admission extension airbag, links to each other with hand bar lower end with screw rod, is loaded on the framework by base plate.

Described air shut-off valve comprises a ratchet, tail end with its in have an air duct cylindrical spool be connected mutually, cylindrical spool is packed in the valve body, ratchet is located at the outside of ratchet, latch is relative with it to be located on the bracing frame of ratchet inboard.

Described mouth and nose respiratory organ, comprise the air diverts blower inlet casing that an end links to each other with joint sleeve, its center has passage, have on the sidewall and turn to mouth, link to each other by the inlet end of joint with mouth breathing device housing, the double action opening and closing plug is packed in the air diverts blower inlet casing, end face closed vent hole, platform cone on the side is corresponding with the passage at the nasal inhaler housing center that is loaded on an end in addition, has the nasal respiration hole on the nasal inhaler housing end wall, and the other end links to each other with the nostril tee T, have spiracle on the mouth breathing device housing wall, mouth rank device is located at an end of mouth breathing device housing, and an end of flexible pipe puts in mouthful rank device, and links to each other with joint.

The body of rod of described hand bar is to be combined by more piece.

Described ratchet is to be made of five ratchets that are uniformly distributed along the circumference.

Also be provided with the check valve that links to each other with source of oxygen on the described upper cover plate.

Described sucker inner chamber is provided with display lamp, is by battery case, and battery, bulb and switch are formed.

The present invention compared with prior art, link to each other with air storing duct by check valve owing to adopted with the device of calming the anger of hand bar interlock, air storing duct links to each other with the mouth and nose respiratory organ by air shut-off valve, the mouth and nose respiratory organ places patient's mouth respectively, on the nose, the recessed position in sucker and patient chest a series of technical measures such as contact, and put into practice the clinical proof of first aid through several examples easy simple to operate is arranged, family numbers of patients is trained a little can both be on top of, every pushing patient cardiopulmonary are promptly blown once for five times automatically, between the two can matching coordinative, closely link up, impel the patient to revive as early as possible, win rescue time and improve the first aid success rate, eliminate the sequela of contagion and first aid in the past simultaneously, first-aid personnel's physical demands is little.
