Description

an emergency respirator

Technical field:

The utility model relates to a medical device, in particular to a respirator used in first aid.

Background technique:

In medical emergencies, assisted ventilation is often required for some critical patients with dyspnea or apnea. However, mouth-to-mouth ventilation in artificial respiration has many factors affecting the operation, and the ventilation effect is difficult to control, and there is a hidden danger of pathogen infection between doctors and patients in artificial respiration. In the future, some simple respiratory first-aid equipment will appear, generally consisting of airbags and masks. However, the ventilation devices in these simple equipment are unreasonable and inconvenient. It brings a lot of inconvenience in first aid, and sometimes the mask needs to be moved. away from the patient's mouth and nose so that the patient can breathe spontaneously. Some simple respirators that use one-way valve ventilation devices are generally designed as face shields, air intake pipes, outlet pipes and one-way valves. This structure causes inconvenience for simple respirators with closed disinfection. Therefore, there is an urgent need for a simple in structure, easy to use, easy to sterilize, and an emergency respirator that is easy for patients to take a breath.

Invention content:

The purpose of this utility model is to overcome the shortcoming existing in the prior art, provide a kind of emergency respirator that is simple in structure, easy to use, easy to sterilize, easy patient's ventilation.

In order to achieve the above object, the utility model provides an emergency respirator, including an airbag, a mask and a mask holder, wherein one end of the airbag is provided with an airbag tailpipe and a connecting pipe, and the other end of the airbag is provided with a turnbuckle , the connecting pipe is pluggably connected to the airbag tail pipe, and the mask is screwed to the mask frame.

An air inlet pipe is arranged between the turnbuckle and the mask frame, and the air inlet pipe is threadedly connected with the turnbuckle and the mask frame.

A sub-bracket is arranged on the mask frame, an outlet pipe is arranged on the sub-bracket, and the outlet pipe is threadedly connected with the sub-bracket.

A valve is further arranged inside the mask frame, and the valve is used to control the gas flow in the mask frame.

The mask is any one of transparent PP material, PE material, or PVC material, and the air bag is circular or oval.

The outstanding advantages of the utility model are: simple structure, convenient use, easy disinfection, and easier ventilation for patients until spontaneous breathing occurs. details as follows:

1. The utility model has a transparent structure as a whole. When rescuing a patient, the color of the patient's lips and face can be observed through the mask, and whether the patient is breathing spontaneously or not.

2. The two ends of the interface of each part of the utility model can be disassembled and assembled quickly and conveniently, and it is also convenient for disinfection after first aid, so that the disinfection is more thorough.

3. The tail pipe of the airbag of the utility model can be connected to an oxygen bottle or a ventilator through a connecting tube, so that it is convenient to establish an artificial airway for the patient in time and connect to the ventilator.

Detailed ways:

Below in conjunction with accompanying drawing, the utility model is described.

As shown in Figures 1 to 2, they are the overall structure diagram of the utility model and the top view of the mask frame part of the utility model respectively. It includes an airbag, a mask and a mask frame, wherein one end of the airbag 2 is provided with an airbag tail pipe 9 and a connecting pipe 1, and the other end of the airbag 2 is provided with a turnbuckle 3, and the connecting pipe 1 is connected with the airbag tail pipe 9 in a plug-and-pull manner. 8 is threadedly connected with the mask frame 5; an air intake pipe 4 is arranged between the turnbuckle 3 and the mask frame 5, and the air intake pipe 4 is threadedly connected with the turnbuckle 3 and the mask frame 5; the mask frame 5 is provided with a sub-support 6 , the sub-support 6 is provided with an air outlet pipe 7, and the air outlet pipe 7 is threadedly connected with the sub-support 6; the inside of the mask frame 5 is further provided with a valve 10, and the valve is used to control the gas flow in the mask frame; the mask 8 It is any one of transparent PP material, PE material, or PVC material, and the airbag 2 is circular or oval.

Before the utility model is used, the patient's vital signs will be observed to check whether the patient's respiratory tract is unimpeded. When in use, the patient takes a supine position, the rescuer is positioned above the patient's head, tilts the patient's head back, supports the patient's lower jaw, so that the patient's airway remains unobstructed, and then fastens the mask 8 to the patient's mouth and nose, and at the same time Extrude the airbag 2, the gas in the airbag 2 flows through the turnbuckle 3, the air intake pipe 4, and enters the mask frame 5. Due to the effect of air pressure, the valve 10 turns to the air outlet pipe 7, and the air outlet pipe 7 is blocked. At this time, the air bag 2. The air intake pipe 3, the mask frame 5, and the mask 8 form a channel, and the gas enters the patient's lungs smoothly. After the patient breathes spontaneously, the extrusion frequency of the air bag 2 should be consistent with the patient's respiratory rate. When the patient exhales, the valve 10 will turn to the air intake pipe 4 due to the effect of air pressure, and the air intake pipe 4 will be blocked. At this time, the mask 8, The mask frame 5 and the air outlet pipe 7 form a channel, and the patient's breath is discharged along the air outlet pipe 7 . The frequency of squeezing the air bag 2 is 12-15 times/min for adults and 14-20 times/min for children. When squeezing the airbag, watch the patient's chest to check whether the ups and downs of the patient's chest are consistent with the ups and downs of the squeezed airbag, and check the color of the patient's face and lips through the mask, whether there is cyanosis, and whether there is fog in the mask. And pay attention to whether the detection valve 10 works normally. If the patient's condition does not improve, an artificial airway should be established in time, and the connecting tube 1 should be connected to an oxygen cylinder or a ventilator. After the utility model is used, each part can be disassembled, which is convenient for disinfection and is ready for the next use.
