Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, in particular to a cardiopulmonary resuscitation and artificial respiration first aid device. Background Art

[0002] The simple respirator is a simple and effective tool for artificial ventilation. It is suitable for cardiopulmonary resuscitation or emergency situations requiring artificial ventilation, such as suffocation, severe dyspnea, or urgent need to increase oxygen supply, especially when the condition is critical and there is no time for tracheal intubation, or when the ventilator fails, the simple respirator can be used to directly supply oxygen, improve tissue hypoxia, reduce related complications caused by hypoxia, buy time for clinical rescue, and improve the patient's quality of life. Compared with mouth-to-mouth breathing, the simple respirator is easy to use, reduces patient pain, has fewer complications, provides appropriate oxygen concentration, and ensures safety.

[0003] In the prior art, the breathing mask of a simple respirator is buckled on the patient's mouth and nose, and the patient is ventilated through a pressurized ball connected to an oxygen source or a medical air source. The specific operation requirements are: the doctor is located behind the patient's head, tilts the patient's head back, and holds the lower jaw to face upward, so that the mandibular angle and the earlobe are in a straight line and perpendicular to the long axis of the patient's body, so as to effectively open the patient's airway and keep breathing unobstructed. At this time, the doctor must use the "EC" technique. The E technique refers to the rescuer's middle finger, ring finger and little finger placed at the patient's mandibular angle, lifting the patient's lower jaw upward to keep the airway unobstructed; the C technique refers to using the thumb and index finger of the same hand to buckle the mask tightly to the patient's mouth and nose to ensure that the mask is airtight and leak-free. This technique combines the action of sealing the mask and keeping the airway unobstructed, and is an important skill when using a simple respirator for ventilation operations. Although this method can deliver oxygen to patients, it is difficult to operate and has high requirements for rescuers. It requires professionally trained personnel to perform effective operations. In addition, the operation process is relatively cumbersome, time-consuming and labor-intensive, and consumes the rescuer's physical strength and energy. It may even waste precious rescue time and is not conducive to the promotion of artificial respiration first aid in scenarios such as cardiopulmonary resuscitation. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a first aid device for cardiopulmonary resuscitation and artificial respiration, which has the characteristics of simple structure, convenient operation, reduced operating difficulty for rescuers and guaranteed rescue effect.

The tension ring is sleeved on the edge of the breathing mask, and a tension belt is provided between the helmet and the tension ring for quick connection and pressing the breathing mask.

[0012] The beneficial technical effects of the present invention are as follows: First, the helmet is quickly connected to the tension belt, and the tension ring makes the breathing mask tightly buckled on the patient's mouth and nose to maintain a seal, thereby avoiding air leakage during ventilation. The sponge lining layer inside the helmet is convenient for sealing and can improve the patient's comfort level. Second, a recessed area is provided at the left end of the cushion, and the patient lies flat and naturally makes the top of the head droop and the lower jaw lift upward, which is conducive to opening the airway and ensuring rapid and smooth ventilation. Third, due to the different body shapes of patients, in order to prevent some patients from sagging their heads and not meeting the standards, ventilation is performed through a medical air compressor, so that the airbag is inflated to facilitate adjustment of the patient's cervical spine height, so that the mandibular angle and the earlobe are in a straight line and perpendicular to the long axis of the patient's body, while ensuring the patient's comfort, it is conducive to opening the patient's airway and saving the rescuer's physical strength. Fourth, when ventilating the patient, the flow control valve can deliver different ventilation volumes according to the patient's weight difference.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figures 1 to 3As shown, the present invention provides a cardiopulmonary resuscitation and artificial respiration first aid device. The daily preparation work must be pre-checked and tested on the device to check whether the air bag 3 and the inflated ball 10 are leaking, whether the exhalation one-way valve 13 and the entire device are assembled correctly, and ensure that the rescued patient can be operated with normal gas supply. The steps of use are as follows: First, connect the simple respirator to oxygen to ensure that the oxygen flow rate is 8-10 liters / minute, which is crucial for providing sufficient oxygen. Second, the patient 17 lies flat on the mat 18, and the recessed area at the left end of the mat 18 allows the patient's 17 head to naturally drop the upper jaw vertically, so that the airway is directly opened. Third, remove foreign objects and dentures in the patient's 17 mouth to avoid aspiration. Fourth, a nylon buckle can be set on the tension belt for convenient and quick connection to ensure the sealing degree of the breathing mask 14. Fourth, during ventilation, the frequency of an adult squeezing the inflated ball 10 is 10-12 times / minute, and the air supply volume is 2 / 3 of the inflated ball 10. For children, the squeezing frequency should be appropriately increased to about 20 times / minute, and the air delivery volume of each squeezing of the inflated ball 10 (children have special balls) should be 2 / 3 of the inflated ball 10. Fifth, when the patient 17 has spontaneous breathing, the inflated ball 10 should be squeezed synchronously, that is, squeeze along with the patient when inhaling to ensure the appropriate amount of air. Closely observe the patient's 17 reactions, such as chest rise and fall, facial color changes, etc., to ensure effective ventilation. At the same time, pay attention to avoid overventilation. If the patient 17 does not open the airway, chest compressions should be suspended during ventilation; if the artificial airway is opened, continue to compress the chest. Sixth, the device should be properly cleaned and disinfected after use, including steps such as disassembly of accessories, soaking and disinfection, rinsing and drying.

[0019] According to the disclosure and teaching of the above description, those skilled in the art to which the present invention belongs may also make appropriate changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the present invention.
